Using Current Issues of Interest in Teaching Grammar
This study investigated the effect of the integrating currents issues of interest into class materials on the students’ achievement in learning grammar. The following question was proposed. Is relating current issues of interest to class materials useful on students grammar learning? It was hypothesized that integrating current issues of interest with class materials in teaching grammar has a positive effect on learning grammar. The study was performed at Islamic Azad University in Hidaj with 60 participants--male and female-- who were majoring in ‘mechanical’ and ‘electrical’ engineering. Since the researcher did not have the possibility of randomizing the subjects, 60 students of two classes who were taking their first semester at university were used for this study; one of the classes as the control group and the other as the experimental group. As Farhady (1995, p. 146) contends: “In classroom research it is unreasonable to expect the director of the courses to randomly assign students to classes for the sake of experimentation.” The subjects were taught for five weeks and finally took an achievement test. After analyzing the results of the test, and by comparing the means of the scores using t-test, it was found that integrating current issues of interest with class materials in teaching grammar lessons did not significantly improve students achievement in learning grammar.

Shortened Telomere Length in White Blood Cells of Patients with Non-Insulin Dependent Diabetes Mellitus (NIDDM)
Type 2 diabetes(TIIDM) aging-related disorder, is caused by a combination of peripheral insulin resistance and ?-cell dysfunction .Recent evidence, however, suggests that TIIDM is additionally characterized by impaired ?-cell regeneration and reduced ?-cell mass .Shortened telomeres have been previously associated with diabetes in several small-scale studies(Zhu et al.,2011). Measurement of telomere length in diabetic patients in different age and different duration of disease and compared with control. Also included the comparison telomere length between male and female for both control and diabetic groups and between patients from genetic origin (mother origin or father origin) and patients from non genetic origin. Genomic DNA was prepared from whole blood extraction using genaid kit and was quantified by Nanodrop .Terminal restriction fragment (TRF) lengths were measured using the Southern-blotting technique .This study was conducted between November 2010- November 2012 and, it was carried out at the diabetic Centre / Merjan Teaching Hospital in Babel Province by taking 54 diabetic patients(Type II DM) with disease duration (0-5),(>5-10 )and (>10 )years ,with age average (35-65 year)and most of them were on oral hypoglycemic drugs. While the study included 18 people apparently healthy that included 9 male and 9 female with age average (35-65 year). The study revealed that telomere length(TL) were differences between males and females of control group. Age- adjusted telomere length were shorter in males than in females of control subjects (13,200 bp ) vs. (11,600 bp), (14,200 bp) vs. (13,000 bp) and (15,100 bp) vs. (13,800 bp),and this differences in TL between males and females decreased as aging increased, while this gender differences in TL was not observed among the diabetic patients .In both the controls group and diabetic subjects, the telomere length were shorter in older subjects than younger for both males and females.

Study the levels of adiponectin, FSH, LH and Sex hormones in Type 2 diabetes (NIDDM)
Background: The hypothalamic/pituitary/gonadal (HPG)axis is central to the mammalian reproductive system. Pulsatile release of GnRH from neurons in the hypothalamus stimulates the secretion of LH and FSH from gonadotropes in the anterior pituitary. It has long been recognized that reproductive function is closely associated with energy balance, and metabolic dysregulation is linked with reproductive abnormalities (Lu et al.,2008). Compare the differences in levels of adiponectin, FSH, LH, testosterone and estradiol between the diabetic patients and control group and in diabetic patients according to the durations of disease for both males and females groups .Also study the relationship between adiponectin and hormones for both gender and for both diabetic groups and control also in diabetic patients according to the durations of disease. The statistical analysis of this study showed that patients with Type 2 diabetes of both males and females had significantly lower in adiponectin levels than control group (P<0.05),but this level of adiponectin significantly higher in females than males for both diabetic groups and control (p<0.05) ,while the levels of FSH and LH had significantly higher in diabetes group than control (p<0.05) ,also significantly higher in females than males for both diabetic groups and control (P< 0.05). The result of hormonal analysis show there were no significant differences in estradiol and testosterone between diabetic groups and control (p > 0.05). According to the durations of disease, the results show significant elevation in adiponectin level in third duration of disease for both males and females groups as compared with first and second duration (P <0.004), while the levels of FSH, LH ,estradiol and testosterone show no significant differences among duration(P>0.05).

Implications of Excess Iron in the groundwater of Igbokoda Areas, SW Nigeria
The groundwater of Igbokoda Coastal Area of Nigeria is characterized by high iron concentrations. Excess iron (Fe) at concentrations above 0.3mg/L in water can give an unpleasant metallic taste and its health effects may include warding off fatigue and anemia. This study therefore assessed the implications of excess Fe in Igbokoda coastal groundwater. The research was carried out using the WHO recommended guideline values, the Langelier Saturation Index (LSI) and Larson Index (LI). Hydrochemical results revealed that the pH ranged from 6.8 – 9.8, EC from 67 – 2440(µS/cm), TDS from 43.55 – 1586 (mg/L) and TH from 66.36 – 369.22mg/L. In addition, the selected anions (mg/L) including HCO3, SO4 and Cl ranged from 15.25 – 152.50, 0.00 – 5.32 and 72.00 – 2592.00 respectively. Calcium varied from19.21 – 104.32mg/L and Mg from 3.36 – 75.01mg/L. Iron ranged between 0.01 and 13.74(mg/L) with Mn from 0.00 – 1.00(mg/L). The hydrochemical contents are within approved WHO standard values for potable water except for EC, TH, Cl, Fe and Mn concentrations that exceeded the standard values in some locations. About 97% of the groundwater samples for this research have TH>80mg/L and may not be suitable for domestic purposes as it coagulates soap lather. The chloride values were higher than approved WHO standard of 250mg/L in twenty one locations representing 54% of the groundwater samples. The high chloride values were attributed to saltwater intrusion in the area and could accelerate corrosion of stainless steel even at values as low as 50mg/L. In this research, all LI values in all groundwater samples were greater than 0.5 while 78% have negative LSI values indicating corrosive water. Both LI and LSI revealed significantly that the groundwater of Igbokoda coastal area is corrosive. High levels of Fe and Mn in the groundwater of the study area can result in discoloured water, stain plumbing fixtures and inflict unpleasant metallic taste on the water. In addition, it could result into diseases of aging (Alzheimer’s disease, other neurodegenerative diseases, arteriosclerosis, diabetes mellitus). The groundwater in the coastal area of Igbokoda must be treated by aeration or chlorination which should be followed by physical filtration to allay the health risks of excess iron in the groundwater of the study area.

Adequacy of financial statement and information for investors decision on the Nigerian stock exchange
This study focuses on the efficiency of financial indicators to influence the decisions of investors. It investigates the effect of information content of financial statements on shareholders’ investment decisions. The study is vital as it portrays the extent to which shareholders of firms listed on the Nigerian Stock Exchanged (NSE) are influenced by the contents of published accounts in their investment decisions. The annual financial reports provided by the accounting system, is considered the main source for information for decision-makers especially the investors. Therefore, the validity and accuracy of the decisions depend on the understanding, reliability and proper analysis of financial statements. In order to determine the relationship between information contents of financial statements and shareholders’ investment decisions, some of the key contents of financial statement were used to derive the proxy variables used in the study, namely profitability, dividend per share, earnings per share, leverage, and liquidity; while shareholders’ investment decisions is represented by change in number of shares. Data for the study were obtained from the published annual financial report of the selected firms. Regression model was employed to establish the relationship between the variables. The findings generally indicate that though shareholders in the Nigerian capital market do not rely much on financial statements as a major determining factor for their investment decisions, still the financial analysis factors constitute the main tool in attracting investment. It was observed that other factors or variables outside firms’ annual reports such as regularity and amount of dividend payment and what is in-vogue or everybody is doing (herding) affect market price of shares and are vital to shareholders’ investment decisions. The study recommends proper awareness creation by the appropriate agencies to enhance shareholders’ understanding of the relevance of published accounts to enable them to know the financial states of the companies (banks) of their interest before making investment decisions. Besides, shareholders should seek the advice of financial analysts so as to be properly guided in their investment decisions.

Electronic structure investigations of 3 and 5- diamino-1,2,4-triazole by UV–Visible , NMR spectral studies and HOMO-LUMO analysis by AB initio and DFT calculations
Quantum chemical calculations of energies, geometrical structures and electronic absorption spectra of 3,5-diamino-1,2,4-triazole (DAT) were carried out by ab initio HF/6-311+G(d,p), DFT (B3LYP/6-311+G(d,p)). The optimized geometric bond lengths and bond angles obtained by HF method show best agreement with the experimental values. Comparison of the observed fundamental vibrational frequencies of DAT with calculated results by HF and density functional methods indicates that B3LYP is superior to the scaled Hartree-Fock approach for molecular vibrational problems. The difference between the observed and scaled wave number values of most of the fundamentals is very small. A detailed interpretation of the FT-IR and FT- Raman, NMR spectra of DAT was also reported. Thermodynamic properties were also calculated and discussed. UV–vis spectrum of the compound was recorded and the electronic properties, such as HOMO and LUMO energies, were performed by time dependent density functional theory (TD-DFT) approach. Finally the calculations results were applied to simulated infrared and Raman spectra of the title compound which show good agreement with observed spectra. The Mulliken charge analysis indicates that the nitrogen atoms of the triazole ring and the amino group attached to the ring are the main reactive centers of 3,5-diamino-1,2,4-triazole. And the temperature dependence of the thermodynamic properties of constant pressure (Cp), entropy (S) and enthalpy change (?H0?T) for DAT were also determined.

Combined effect of surface roughness and deformation on the performance of a Ferrofluid based squeeze film in rough porous circular plates with porous matrix of variable thickness
An attempt has been made to evaluate the effect of surface roughness and deformation on the performance of a magnetic fluid based squeeze film in rough porous circular plates considering porous matrix of variable thickness. The stochastic model of Christensen and Tonder has been adopted to characterize the roughness of the bearing system. With appropriate boundary conditions, the associated Reynolds’ type equation has been solved by invoking the dilog function, to derive the expression for pressure distribution resulting in the calculation of load carrying capacity. It is observed that the adverse effect of transverseroughness gets aggravated due to the bearing deformation. But the situation remains fairly improved in the case of negatively skewed roughness for a large range of bearing deformation with a suitable strength of the magnetic field. Further, it is appealing to note that this positive effect gets augmented with a proper selection of thickness ratio parameter associated withvariable film thickness.

Meaning in life as constructed by male adolescents of alcoholic parents
We do not choose our parents, and when one parent is impaired by alcohol most of the time, this brings developmental challenges for the young adolescent. Alcoholism occurs in India as in other nations, but here there is a greater sense of shame attached to it. This present study looks at the experience of adolescent sons living with an alcoholic parent by means of a qualitative phenomenological design. The sample were selected using purposive sampling. Thematic network analysis is used to analyse data. This involved organizing the data to three levels reflecting salient themes i.e. basic, organizing and global themes. Semi structured interview with five adolescent aged seventeen to twenty were recruited from Bangalore city. Five global themes emerged form the analysis – need for praise, building self esteem, support, religious faith and belief, being misunderstood by others. What stood out was the boys accepted that alcoholism was a disease and that it was not their father’s fault, and remained loyal to their parents.

A Relational Thinking Process of Field Dependent-Independent Students in Solving Mathematical Problems
The objective of this present paper is to analyze the relational thinking process of the Junior High School Students with field-dependent and –independent cognitive styles in solving mathematical problems. Two students were chosen as the research subject, one with dependent- cognitive style, the other, independent cognitive style. The data were collected through in-depth interviews after the subjects solved mathematical problems. All data were video-recorded. The credibility of the data was obtained through meticulous or continuous/consistent observations and time triangulation and analyzed using a flow model consisting of three-path activities occurring simultaneously: data reduction, data presentation and conclusion drawing. The results of the analysis showed that the relational thinking process of the field dependent student in solving mathematical problems is done by making relation among and in the three core elements: understanding the problem, answering the questions and reviewing, meanwhile, the field independent student, besides building relation among and in the three core elements like the field dependent students, chose some strategies.

Investigation of 8 Channel WDM and ODTM PON for different Modulation Formats
Abstract —to support higher data rate optical networks play a vital role. The high bandwidth potential of optical fiber can be explored by exploiting multiplexing techniques like wavelength division multiplexing (WDM) and Optical time division multiplexing techniques (OTDM).This paper evaluates the performance of 8 channel WDM and OTDM passive optical network (PON) for 150 km using PIN and APD(avalanche photodiode) receivers. It is found that WDM passive optical network (PON) yields better performance. Hence, it is further investigated for different data rates and modulation formats. It is found that RZ modulation format provides better Max quality factor (Q) than NRZ modulation format up to a distance of 100km.Beyond 100km the Max quality(Q) factor decreases due to dispersion and nonlinearities. The current access networks and next generation passive optical networks (NG PON) has also been reviewed.

Prevalence of Group A beta-haemolytic Streptococcus pharyngitis and drug resistance in community-acquired pharyngitis in Pakistan
Streptococcus pyogenes infections have increased significantly in the last few decades. This increase in the infection rate is primarily due to development of resistance against macrolides and tetracyclines. A total of 250 pharyngeal swab samples were collected during four months time period. Samples were divided in to four groups; age group 1-4 years, 5-12years, 13-18 years and ?18 years. Isolates obtained were run for the evaluation of antibiotic resistance against ten antibiotics by using Kirby-Bauer's method/disc diffusion method. Out of 250 samples, 71 were confirmed as S. pyogenes. The prevalence of GAS pharyngitis in different age groups was; 16.0% in age group 1-4 years, 48.8% in age group 5-12 years, 14.8% in age group 13-18 years and 20.4% in age group ?18 years. All the isolates were completely sensitive to penicillin, amoxicillin-clavulanic acid, ceftriaxone and vancomycin whereas erythromycin, azithromycin, tetracycline, clindamycin, cholarmphenicol and levofloxacin resistance was recorded as 42.42%, 39.43%, 54.92%, 4.22%, 14.08% and 1.40% respectively. Data suggested that GAS pharyngitis was most prevalent in the age group 5-12 years and S. pyogenes was completely sensitive to penicillins and other cell wall synthesis inhibitors. However, higher resistance rates against macrolides (erythromycin and azithromycin) present an alarming situation in Pakistani population.

Effect of Steel Strength on Sectional Ductility and Moment Capacity of Reinforced Concrete Section
Frequent occurrence of recent earthquakes in South Asian region has inspired the civil engineers to become more concern about earthquake resistant building design. In order to construct a building in a high seismic zone, the flexural members like beams, must have adequate ductility along with enough strength. Ductility is a solid material's ability to deform under tensile stress. To evaluate the flexural ductility, it is necessary to conduct non-linear moment-curvature experiment or numerical analysis. Moment curvature is a method to determine the load-deflection behavior of a concrete section using nonlinear material stress-strain relationship. As experimental analysis is time consuming and costly, a quicker and cheaper approach numerical analysis can be performed. In this paper, results of a numerical program conducted on sectional ductility behavior of a rectangular concrete beam are presented. Eighteen cross sections, with three different reinforcement ratio (0.007, 0.010 and 0.013), two different yield strength of reinforcement (400MPa-nominal strength steel and 500MPa-high strength steel) and three different concrete compressive strengths (25MPa, 30MPa and 35MPa) have been built and analyzed. An effort is made to order the performance of the samples according to moment capacity and ductility. From the program it has been observed that, moment capacity is higher in highly reinforced section. But more ductility is obtained from a lower reinforced high strength steel beam. The use of higher strength steel helps to maintain minimum level of flexural ductility along with higher flexural strength. It also leads to reduce construction cost by reducing dimension of a concrete section and by reducing steel requirement.

Effects of Vehicular Traffic on Employee: A Case of Scacom Ghana Limited
Commuters in Accra, Tema and major cities of Ghana continue to suffer heavy vehicular traffic jams each working day, particularly during the peak hours, when most people travel to their work places or to school and back. Formal sector employees, including those from Scancom Ghana, are spared of the negative effects of this phenomenon which include loss of working time, lateness, commuting stress and fatigue among others. However, in order to avoid these negative effects of traffic jams mentioned earlier, some workers cut down on their sleep and get up very early to be able avoid the enormous traffic congestions. This also comes with loss of sleep and associated stress and fatigue. Similarly, some workers leave the office earlier than required to be able to “beat” the huge traffic congestion and reach home early. Through a survey, this study sought to find out how the traffic congestion in Accra and Tema affect employee productivity, particularly among workers who use the major streets to the Central Business Districts and Tema. Using employees of SCANCOM Ghana Ltd, the study also sought to evaluate workers’ views on the extent to which traffic congestions affect employee productivity. The study findings revealed that while majority of the respondents agreed that vehicular traffic congestions moderately or seriously affected employee productivity, they were still able to meet their daily work targets, their productivity was not affected by the traffic jams they encountered.

The Relationship between Personality Traits and Employee Performance: The Case Of Barry Callebaut Ghana Limited
It is important for one to understand that every employee comes into the organization with a set of unique and distinct personality traits or characteristics. The study tries to investigate the relationship between the personality traits of 60 employee in Barry Callebaut Ghana Limited and their performance on the job. Personality trait was measured using the Eysenck Personality Inventory. Work performance on the other hand was measured using a structured appraisal questionnaire. The personality traits of the employees were then analyzed by mapping the links between the two major traits; Extraversion and Neuroticism. The study showed a weak inverse correlation between the two personality traits and performance. The correlation between Extraversion, Neuroticism and Performance is r =0.1 and r =0.2 respectively. This showed that Extraversion and Neuroticism have a weak negative relationship with performance but Extraversion has a good negative relationship with performance compared to Neuroticism or Neuroticism exhibited a stronger inverse relationship with performance compared to Extraversion. It is therefore recommended from this study to management of Barry Callebaut that they should employ more of extroverts than neurotics. Employers must factor personality assessment into their recruitment and selection criterion so as to examine how well potential employees will fit into a particular job vacancy.

The relationships between cultural intelligence, reading proficiency and vocabulary knowledge of Iranian EFL students
: Now days Culture has become one of the factors that create effects on the performance of the students through four skills and discussing its relationship with one of these skills is a controversial issue. The aim of the present study is to investigate whether there is any significant relationship between intercultural intelligence (known as CQ) awareness and reading proficiency (RP). The participants were 250 Azad University students of English translation with the same level of proficiency but different genders. To this end, the participants first were provided with CQ questionnaire by (Ang et al., 2007) and vocabulary tests which was developed by Paul Nation taken from his website as well as a reading proficiency test developed by Sadeghi and Everatt (submitted). The results of the present paper indicates that there is no significant relationships between cultural intelligence band score and reading proficiency, however a significant relationship among metacognitive factors as one of the four important sub-categories of cultural intelligence was evident. When looking into vocabulary, while a positive significant correlation with CQ band score was found, again similar to the reading proficiency skills a significant relationship between vocabulary knowledge and metacognitive factors was evident. The fact that the results show no correlation between either reading proficiency skills or vocabulary knowledge with cognitive factor represented in the questionnaire needs further research. Key terms: cultural intelligence, culture, reading, proficiency, vocabulary

Reduction of Electromagnetic Interference Cuk Converter for Aircraft Application
A significant increase of the electrical equipment in modern aircrafts is leading to an increase in the demand for electrical power. The usual electrical power distribution in aircraft applications is done via a three-phase 415 Vac grid. A new trend of DC distribution is emerging employing a 270 Vdc grid. With the advancement in the power semiconductor devices and power transformers, DC-DC converters are designed with frequency ranging up to MHZ range. Increase in the switching frequency along with the sudden change in the current di/dt or voltage dv/dt generates higher order harmonics which leads to Electro Magnetic Interference (EMI). EMI noise creates malfunctioning of the circuit and also leads to miscommunication within the system and sometimes leads to device failure. Which is an undesirable condition as far as airline is considered. Hence the reduction of EMI noise is of uttermost important. This paper focus on the reduction of EMI using passive filter along with modified PWM carrier modulation technique. A circuit model for the prediction of conducted emissions due to DC/DC converters in an aircraft black box system is proposed and corresponding attenuation method is been analyzed.

A Wavelet Transform based SVM Analysis of ECG Signals - Detection of Cardiac Abnormality
This paper presents a new approach to the Automatic detection and classification of electrocardiogram (ECG) signals is of huge importance for diagnosis of cardiac abnormalities. A method is proposed here to classify different cardiac abnormalities like Ventricular Arrythmias, Myocardial infarction,Myocardial hypertrophy and Valvular heart disease. Support Vector Machine (SVM) has been used to classify the patterns inherent in the features extracted through Continuous Wavelet Transform (CWT) of different ECG signals. CWT allows a time domain signal to be transformed into time-frequency domain such that frequency characteristics and the location of particular features in a time series may be highlighted simultaneously. Thus it allows accurate extraction of feature from non-stationary signals like ECG. Then the support vector machine (SVM) with Gaussian kernel is used to classify different ECG heart rhythm. In the present work, SVM in regression mode has been successfully applied for the classification of cardiac abnormalities with good diagnostic accuracy.

Changing Trends in Root Coverage Procedures using Choukroun’s Magic Wand (Platelet Rich Fibrin): A Review
Esthetics is the science of beauty and encompasses almost every field of dentistry. Gingival recession is defined as the oral exposure of the root surface due to displacement of the gingival margin apical to the cement-enamel junction and it is regularly linked to the deterioration of dental aesthetics. It has been associated with many factors such as inflammatory periodontal disease, developmental anatomic abnormalities (aberrant frenal attachment, thin bony plate), toothbrush injury, tooth malposition and iatrogenic factors. Among the various treatment modalities for root coverage, Coronally Advanced Flap (CAF) procedure demonstrates a high percentage of root coverage with a high predictability and without significant post-surgical complications. Management of gingival recession using Choukroun’s Magic Wand i.e. Platelet Rich Fibrin along with CAF, undoubtedly is a promising treatment modality for root coverage in vogue and should definitely be explored in future.

A one-step conversion of propane and butane gas-fraction into methanol
The present study investigates the oxidative-conversion of propane-butane (C3–C4) fraction to methanol via a proposed vapor–gas system: C3–C4 + O2 + h?/HN?3 ? 2??3?? + C2H4 + C3H6. Experiments were performed by feeding propane-butane fraction, oxygen, and nitric-acid into a photo-chemical reactor under mild conditions at a temperature of 100oC, an atmospheric pressure (P = 1 atm.), and under the influence of electromagnetic radiation using visible-light excitation at a wavelength ? = 420 nm, and at reaction-times (tr) between 2 – 120 minutes. The major oxidation-products are methanol, ethylene, and propylene. From this approach, methanol with 90 % selectivity can be achieved at a single-pass C3–C4 conversion level of 10 %. Quantum-chemical calculations for the oxidation reaction of C3–C4 by hydroxyl radical (via HN?3 photo-dissociation) were performed using the density functional theory (DFT) method at the B3LYP/6-311++G(3df,3pd) level, and the calculation-results are broadly consistent with the experimental data. In a strict sense, the applied technique herein for the oxidation of C3–C4 to methanol, and the valuable semi-products (alkene), as well as to enhances the regeneration of nitric-acid, apparently finds physico-chemical justification.

The Influence of Gender and Age on Computation of Fractions at the Primary School Level; Kenyan Case
It is probable that performance in mathematics at the standard eight classes in Kenya is a reflection of the pupil’s mathematical ability carried forward from standards seven, six and other classes of the primary tier. Gender disparities have persisted in the general performance of this subject, with notable differences in topics like geometry and algebraic fractions at secondary level. This study set out to investigate the influence of gender and age on computation of fractions by the primary pupils in Kenya and its findings were hoped to make a difference in performance of similar topics at secondary school level. The research was carried out in Bungoma County, Kenya. It involved 320 pupils and 8 teachers of mathematics from 8 primary schools. Data were collected by means of a diagnostic test for pupils and a questionnaire for teachers of mathematics. Inferential statistics, namely the t-test and the Pearson r, and frequency distributions were used in data analysis. The study revealed that the pupils had some knowledge of fractions but they encountered a lot of difficulties in computing work on fractions, which limited their level of understanding the topic and that gender had little or no influence on the pupils’ ability to compute fractions at the primary level; while age did. On the basis of the findings, the researcher recommends that teachers be sensitized on age differences in the learning of fractions.

Factors Affecting Retention and Participation of Students in Basic Education in Sub-Saharan Africa: A Case of Kenya
The Government of Kenya started the implementation of Free Primary Education programme in January 2003 and Free Day Secondary Education in 2008. Basic education is critical as it lays a foundation for the subsequent levels of education. To implement the Free Primary Education, the Kenya Government progressively increased budgetary allocations to primary education from an expenditure of Kshs 745.08 million in 2001/2002 financial year to Kshs 18.30745 billion in 2007/2008 financial year. While there has been improvement in pupils’ enrolment in primary and secondary schools, its effect on retention and participation of pupils/students in basic education has not been determined. This paper, therefore, looks at factors that affect retention and participation of pupils/students in basic education. Changes in enrolment should be accompanied by improvement in quality of instruction and retention if the set goals of basic education are to be achieved.

Investigation of the relationship between the p wave and s waves within the basement complex of Northern Nigeria
The relationship between p wave and s wave is dynamic, and it is majorly a function of terrain. Knowing the relationship between p wave and s waves for any particular terrain is of vital important for both seismic exploration and geotechnical analysis. The aim of this research work is to establish an absolute relationship between the p waves and s wave seismic velocities within the basement complex. This factor (ratio) will be a guide to a better estimate of shear wave velocity during data analysis that will enhance exploration and site characterization in areas where vertical geophones will be exclusively used for data acquisition. With a bid to achieving this aim, seismic survey was carried out within some locations in the basement complex. The data was processed to generate the p wave velocity models and s wave velocity models independently. The result revealed that both the p waves and s waves from the tomographic model generally increase with depth. The ratio of these p waves and s waves velocities ranges between 1.767981 to 1.999435347. The average representative value for these p waves and s waves velocities ratio was determined to be 1.794860218. The result also revealed that the ratio of p waves and s waves does not genially increase with depth. Therefore, a value of 1.8 approximated to one decimal place, can be taken as a representative value for the ratio between p waves and s waves down to a depth of 40 m within the basement complex. However a value of 1.9 to 2.0 can be adopted as a ratio between p and s wave velocity within the basement complex beyond the depth of 40 m.

Study on the effect of number of Sprouts per stand on yield and yield components of Cassava in Ado Ekiti, Nigeria
Field trials were carried out at the farm of Livestock development unit of Ekiti state Ministry of agriculture, Erinfun, Ado Ekiti (7°40? N, 5°15? E) in 2010/2011 and 2011/2012 cropping sessions to assess the effects of sprout number per cassava stand on the performance of cassava Manihot esculenta. The treatments which represented the number of shoots allowed to survive from sprouted shoots per stand were single shoot; double shoots; triple shoots and multiple shoots. At four weeks after planting (4WAP), sprouted shoots were detached to the required number per stand in each treatment. Multiple shoots produced the tallest plants while single and double shoots per stand gave the shortest plants. Single shoot per stand produced the highest stem girth figure, number of initial and final branches, fresh shoot biomass, number of tubers per plant as well as tuber yield per hectare. While the percent peel per tuber was lowest in the single and double shoots per stand, the highest percentage of peel per tuber was recorded in the multiple shoots cassava plants. It is concluded that sprouted cassava should not be allowed to be more than two shoots per stand for optimum cassava tuber yield.

A Review on Heat Transfer of Fluids in Curved and Coiled Geometries
The objective of the present study is to give a review on heat transfer characteristics of fluids in curved and straight tubes for various parameters and under different experimental conditions. The heat transfer can be increased by two techniques mainly like application of external forces or by modification in surface geometry of the fluid passages. Surface geometry modifications like bending of straight tubes into curved coils are effective and efficient method of heat transfer enhancement. In this paper, various correlations proposed based on experimental heat transfer data by earlier investigators are presented to support the enhancement in overall heat transfer coefficient in curved tube and in straight tube heat exchangers. However, comparison of experimental overall heat transfer coefficient in helical coil and straight tube heat exchangers are found to be limited in the present literature.

Effect of Supplementing Grazing N’dama Calves with Urea Treated Maize Stover and Centrosema pubescens
Maize stover consists of the leaves and stalks of maize plants left in a field after harvest and it makes up about half of the yield and is similar to straw. Ensiling maize stover with urea makes it a urea treated maize stover. Centrosema pubescens is a legume in the family Fabaceae, subfamily Faboideae and tribe Phaseolae. It is native to Central and South America and cultivated in other tropical areas as forage for livestock. An experiment was conducted to investigate the effects of urea treatment on chemical composition; feed intake, blood urea and ammonia of maize stover. The potential of such a stover for growth performance of calves were investigated using 8 N’dama calves of 5 to 8 months of age and an average initial live weight of 92.5 kg. The animals were divided into two groups each of which were individually fed to appetite on basal diets of either untreated maize stover and Centrosema pubescens (Diet T1) or 5 % urea treated maize stover and Centrosema pubescens (Diet T2) for 90 days. In addition all the calves were allowed free access to mineral/vitamin blocks and ample drinking water ad libitum. Urea treatment increased the crude protein (CP) content of maize stover in Diet T2 by 22.12% and also a highly significant difference (p<0.01) in the crude fibre (CF) content over the untreated stover in Diet T1. Besides, compared with the untreated stover, urea treatment brought an improvement of 28% in daily feed intake. These improvements in terms of chemical composition, daily feed intake and dry matter intake led to a highly significant (p<0.01) live weight gain of animals fed on the urea treated stover diet compared with those fed on the untreated stover diet. However, there was no significant difference (p>0.05) in blood urea levels but significant existed in feed cost/kg gain and linear body measurements between the animals fed on Diet T1 and those fed on Diet T2. Generally, with the added advantage of Diet T2 being more cost effective than Diet T1, feeding urea treated maize stover may be considered as one of the strategies that bring about an efficient utilization of crop residues for livestock feeding in Eastern part of Nigeria. However, its economic advantage over other alternatives must carefully be examined under the prevailing price conditions before it is implemented in an area.

The Philosophy of Phenomenalism with Special References to Sri Narayana Guru and George Berkeley: A Comparative Study
Philosophy begins with, an enquiry into the essence of the external world. Indian and Western Philosophers, were agitated the philosophical question that, how many ultimate realities are there in the world? To answer this question, the foremost, Ancient Greek philosopher, by Thales (624 B.C) declares that ‘Water’ is the only ultimate reality. Anaxamines (588 BC) says 'Air', Heraclites (535 BC), added 'Earth', Empedocles (495 BC) says, 'Fire', Democritus (460 BC) opines 'Ether' as the fifth element. Similarly, Socrates, Plato (427BC) and Aristotle (384 BC) observe that, though these five elements are permanent and eternal but the percipient is not observe these elements as it is. It is something other than what it is. It is called as 'Appearance' or 'illusion' or ‘M?ya’. From the dawn of philosophical enquiry, philosophers were puzzled at this problem which never agitated the minds of common man. The modern western Philosophers like Berkeley, Kant, Russell and Ayer were also discussed the problem of appearance.

Intelligent driver model automation system in vanet
In this paper an algorithm for alternate path is implemented. The evaluation matrices for the shortest available path are velocity of the leading vehicles, distance from source to destination and time delay to reach to destination. Simulation shows, if there is congestion on the current path then the node will find for an alternate shortest path in digital map to the destination. This will avoid the congestion on a single road at intersection points. But the system has to make search every time the vehicle found congestion on the way for destination. The graph given below shows, the traffic moving according to the pause time on the roads due to any reason like traffic light, accident or any other obstacle. X axis is labeled as time delay and Y axis contained no. of nodes/packets moving towards an intersection point to destination. Whenever the no of nodes becomes more, the pause time will be increased. Upper and lower points in the graph show congestion. At these points, where the graph goes upwards, the congestion is increased at a single intersection point. But where the graph goes downwards, the congestion is reduced to a lower value; because some nodes used alternate route/path to reach to the destination.

Succession planning - a key for organizatinal success in twenty-first century
Henri Fayol (1841-1925), French pioneer of management history, was among the first to recognize and document the universal organizational need for succession planning. However, effective leaders down through the centuries have developed and implemented succession plans for their organizations. There are many leaders today who give little or no “thought to the conclusion of their leadership and so they do little to prepare for it. However, when suddenly faced with leaving their office, they realize that much of their work will have been in vain unless there is a capable successor”.

Translation quality and grammatical proficiency: indirect speech translation from English to Persian
By adopting a language-oriented, problem-solving perspective, the present paper investigated the effect of grammatical proficiency on translation quality when translating English indirect speeches into Persian and the methods Iranian translators use to translate such a structure. A null hypothesis was formulated and 30 MA translation studies students were randomly chosen to take part in two tests: advanced grammar and translation test. A correlation test was used to determine the degree of go-togetherness between the two sets of scores. The result (rXY=0.824) rejected the null hypothesis, indicating a strong positive relationship between the two variables. Also, by analyzing translations, translated indirect speeches were categorized into five classes: Censorship, Lexical Translation, Free Translation, Direct Translation and Correct Translation. Finally, a simple model for translating English indirect speeches was proposed. The result indicates a gap in participants’ English knowledge which requires further studies to investigate the reason behind this shortcoming in Iranian context. The proposed model can be used in forming problem-solving curriculums for translation courses and further research is needed to cover other aspects in this respect.

DC-DC Converter Fed Maximum Power Modeling and Simulation of Distributed Generation for Photovoltaic Applications
This paper proposes Artificial Neural Network (ANN) model for the required DC-DC Converter Duty Cycle feeding Maximum Power to resistive load to be used for distributed generation (DG) applications. It proposes a PV module when coupled to a load through DC-DC Converter to supply this resistive load with the maximum power from the PV module. Some of DC-DC converters topologies are discussed in brief with concentration on Cúk and SEPIC Converters operations. The mechanism of load matching is described to give the required converter duty cycle at maximum power point (MPP). Relations in 3D figures are introduced for the most probable situations for irradiance and temperature with the corresponding PV voltage and current. Also, 3D figures for the desired duty cycle, output voltage and current of DC-DC converter to gain the maximum power to the resistive load at various irradiance and temperature values.

Challenges of increasing student intake in engineering disciplines - the case of university of mines and technology, Tarkwa
Engineering has played a critical role in increasing the health, technology and quality of life of humans in the last 50 years. For efficient and effective practice of engineering, people who aspire to be engineers should be groomed in an environment where quality is assured. In Ghana, the need to train more engineers and governments policy of increasing student’s intake by about 10% each year has raised the number of student’s enrolment in all the engineering disciplines to higher levels. Over the past twenty five years, the University of Mines and Technology (UMaT), with its strategic location, industrial environment, good academic facilities and capable staff has been an excellent place for training graduates of proven ability in the engineering disciplines. UMaT has produced a high caliber of engineering graduate in the mining and its allied disciplines. Student enrolment in the University has seen a gradual increase from the early 1990’s to date. With increasing students’ intake and the slow level of infrastructural development, lecture theatres cannot cater for combined classes for courses being undertaken by students. This has resulted in pressure on academic facilities such as lecture rooms, laboratories, libraries and computers. This also implies an additional work for technicians, laboratory assistant and lecturers handling such students. It is important that government and stake holders in the tertiary education restructure and provide more funding for engineering education. The study looks at the challenges of increasing student intake in the engineering discipline and effort to be made in solving these problems. To provide an in-depth analysis to the issue at stake, available literatures were examined, available facilities were assessed and a general interaction with stakeholders including students, laboratory technicians, lecturers and administrators were employed.

Nutritional enhancement of whole cassava starch residue by biodegradation with fungi SPP
Treatment of crop residues with some species of fungi can enhance their digestibility. This study investigated changes in the nutrient composition of Cassava Starch Residue (CSR) biodegraded with two selected fungi: Aspergillus niger and Trichoderma viride. The experimental designed was a 3x4 factorial arrangement. Biodegradation of CSR for 21days at 300C recorded a significant biomass loss of 33.11% (A. niger), followed by 30.01% (combination of A. niger x T. viride) compared to 27.44% (T. viride). The crude protein increased significantly (P>0.05) from 4.05% to 7.16%, 6.84% and 6.88% within 14days for A. niger, T. viride and combination of A. niger x T. viride respectively. Similarly, the fibre in Cassava Starch Residue decreased from 17.07% to 10.31%, 12.83% and 11.89% for the A. niger, T. viride and combination A. niger x T. viride treatments respectively with a corresponding effect of 2897.1%kcal/kgDM, 2719.2kcal/kgDM and 2739.1kcal/kgDM in the level of metabolisable energy. Cellulose was extensively degraded in all the treatments (P>0.05) than the hemicellulose. Results of this study suggests that fungal biodegradation of whole cassava starch residue is regulated by a complex combination of various factors and consequently enhanced its nutritional profile.

Comparison of the effects of CO2 laser therapy and topical corticosteroids for treatment of oral lichen planus lesions
Oral lichen planus (OLP) is a T-cell-mediated chronic inflammatory oral mucosal disease of unknown etiology and patients with symptomatic lesions usually require treatment. Topical corticosteroids are widely used as the first choice of treatment. Laser therapy is a new method of treatment for symptomatic, resistant oral lesions. CO2 lasers have been used to treat multi-centric lesions and lesions in difficult areas. The aim of this study was to assess the effects of CO2 laser therapy and compare them with topical corticosteroids in the treatment of symptomatic OLP. In this interventional clinical trial ,thirty-six patients with symptomatic OLP were randomly allocated into two groups. The experimental group consisted of patients treated with a CO2 laser and the control group consisted of patients who used a topical steroid, namely0.1% dexamethasone mouthwash. The laser group was treated withCO2 laser ablative therapy in2 consecutive sessions during one week, in which2-3mm of normal tissue bordering the lesion was ablated. The control group used the steroid mouthwash 3 times daily in affected sites for 4 weeks. The visual analogue scale (VAS) used for pain and discomfort evaluation. Clinical data and treatment responses were graded according to Thongprasom criteria. Patients underwent a follow-up 2 months after the last treatment session to assess for recurrence of lesions. Collected data were analyzed using SPSS software version 15.Chi square tests and repeated measurement tests were used for analysis of appearance score, pain score, and lesion severity modification in this study. The laser group included 4 male and 14 female patients with a mean age of 45.89 years and the corticosteroid group consisted of 6 male and 12 female patients with a mean age of 47.68 years. Total of 112 oral lesion sites in both groups existed. The mean duration of lesion presence in the oral cavity was 5.67 months in the laser group and 5.53 months in the corticosteroid group. At the end of treatment, The mean VAS in the laser group was 4.83 ± 1.098 and in the corticosteroid group was 4.72 ± 1.32. The most common type of lesion according to the Thongprasom criteria had a score of 3 (white steria with atrophic area > 1cm2) in both groups. Chi square tests did not identify any difference between the two groups with respect to mean age and sex distribution (P value >0.05). Appearance scores, pain scores, and lesion severity were reduced in both groups after treatment according to repeated measurement tests, but no significant differences were found between the two groups .However , more accelerated pain reduction was found in the laser group, as indicated by the slope of the repeated measurement graph. No significant differences were observed across groups in terms of the response and relapse rates, according to the Mann-Whitney U test. (P value >.05). This study demonstrated that CO2 laser was as effective as topical corticosteroid therapy and it may be considered as an alternative treatment for symptomatic OLP in the future. Key words: oral lichen planus, CO2 laser, topical corticosteroid

Modelling the stochastic boosted regression trees (brt)’salgorithm on ground level ozone (o3) concentration
This paper aim to discuss the preliminary study of modelling algorithm setting of Stochastic Boosted Regression Trees (BRT) using R statistical software. The ground level ozone (O3) concentrations from a Malaysia’s air quality monitoring station was used as a case study. The new approach; BRT developed by Friedman (2001), Friedman (2002) and adopted by Yahaya (2013) in air pollution studies. BRT is differ substantially from traditional regression-based approaches. BRT are constructed of multiple regressions models which finally produce a single ‘best iteration’ model to optimize prediction performance. Sensitivity testing of model been carried out to determine the best parameters’ setting which are number of trees (nt) (1000-10000), learning rates (lr) (0.005-0.5), and interaction depth (tc) (1-10) to suits the ozone data. Results indicated that the BRT analysis algorithm best modeled with the best combination of parameters lr=0.001, tc=5 and nt=5301 that achieves minimum predictive error (minimum error for predictions). The algorithm model would crucially best provided clear benefit for air pollution study and their ability to model complex variable interactions and non-linear effects.

Purification and performance of emission characteristics on two stroke petrol engine using bio-gas as an alternate fuel
This project provides information about energy system by the use of bio gas... Biogas contains primarily CH4 with the balance being mostly CO2 and a small amount of trace components. Now a day’s alternate fuel appears during possessions, by better understanding its components, biogas can be processed and utilized in a more efficient, cost-effective way because of reducing fuel cost, demand of fuel, and emission influence in global warming. The most important of this work is, to produce bio gas from organic waste and reduce the usage of petrol fuel. The increase in population leads to depletion of diesel fuel. Another reason is instead of disposing the organic waste in landfill, this can be converted into a useful product (bio-gas). The bio gas can be stored in a cylinder and be placed in a luggage side box of a vehicle. A regulator is fixed on the top of the cylinder. A hose tube from a vacuum kit which is placed beneath the seat is fixed to the cylinder, so that the gas can be passed to the carburetor. The needle of the carburetor is taken out and the gas would pass on the engine directly. The air filter is partially closed in the vehicle. On kicking the bio gas from the cylinder easily pass on from vacuum gas kit to engine. A spark plug which is above the engine is used to burn the biogas. In this manner, bio gas can be used run the vehicle. The pickup and efficiency is more comparing the existing system of the vehicle has not been reduced by using bio gas. A two Stroke Petrol engine is used for this project, 2 Kg Cylinder is used. It gives 110 kilo meter for one liter of bio gas. So that it can be used in the presented vehicle without any modification. So, the compression ratio of the engine is also high 15:1 Due to high compression ratio power developed by the engine is also high. By less consumption of the fuel, the power produced is more. Petrol produces more toxic gases like HC, CO etc...But we find that methane is less toxic, and emission is very less eco-friendly compare to petrol. It makes “GREEN EVOLUTION”.

Bacteriological Status of Water Melon (Citrullus Lanatus) Sold in Mile III Market, Port Harcourt
The study was carried out to investigate the bacteriological status of freshly sliced water melon in mile III market Port Harcourt. A total of 20 sliced water melons was collected while one whole water melon collected was used as control in this study. The control sample was properly washed with sterile water and sliced aseptically. A sterile knife was used to cut 1.0g from each water melon sample and homogenized on a sterile mortar and pestle. The resultant homogenate was pipette (1.0ml) into 9.0ml of distilled water and serially diluted. The 104 dilution was plated out on Nutrient and MacConkey agar plates respectively using spread plate technique. The plates were incubated at 370c for 24 hours. The cultured plates were examined for colony growth and identification of isolates. The result showed that bacteria isolated from the sliced water melon were Staphylococcus aureus, Escherichia coli , Bacillus spp and Proteus with percentage bacterial count of 414 (45.8%). 324 (35.5%), 144 (15.8%), and 30 (3.3%.) respectively. The control sample showed a scanty growth of staphylococcus aurus. In conclusion, since the control had only a colony of staphylococcus on culture plate after it has been hygienically processed, contamination of the sliced water melon maybe due to poor sanitary condition employed by the vendors during processing and packaging. This is of public health concern as these organisms are known causes of food born diseases and food poisoning.

Experimental Investigation Of The Performance Of A Ground-Source Heat Pump System For Buildings Heating And Cooling
Geothermal heat pumps (GSHPs), or direct expansion (DX) ground source heat pumps, are a highly efficient renewable energy technology, which uses the earth, groundwater or surface water as a heat source when operating in heating mode or as a heat sink when operating in a cooling mode. It is receiving increasing interest because of its potential to reduce primary energy consumption and thus reduce emissions of the greenhouse gases (GHGs). The main concept of this technology is that it utilises the lower temperature of the ground (approximately <32°C), which remains relatively stable throughout the year, to provide space heating, cooling and domestic hot water inside the building area. The main goal of this study is to stimulate the uptake of the GSHPs. Recent attempts to stimulate alternative energy sources for heating and cooling of buildings has emphasised the utilisation of the ambient energy from ground source and other renewable energy sources. The purpose of this study, however, is to examine the means of reduction of energy consumption in buildings, identify GSHPs as an environmental friendly technology able to provide efficient utilisation of energy in the buildings sector, promote using GSHPs applications as an optimum means of heating and cooling, and to present typical applications and recent advances of the DX GSHPs. The study highlighted the potential energy saving that could be achieved through the use of ground energy sources. It also focuses on the optimisation and improvement of the operation conditions of the heat cycle and performance of the DX GSHP. It is concluded that the direct expansion of the GSHP, combined with the ground heat exchanger in foundation piles and the seasonal thermal energy storage from solar thermal collectors, is extendable to more comprehensive applications.
