Titanium (Ti) is a major impurity in the economic Carboniferous and Cretaceous sedimentary kaolin deposits in Egypt. It is found that Ti is present as an independent mineral phase rather than in the crystal structure of kaolinite. Ti occurs mainly as uniform very fine-grained and rounded anatase crystals in pockets within the kaolin mass of all deposits. The optical properties of kaolin (brightness, Lab color, whiteness and yellowness) are improved only when the coloring impurities are removed. In this paper, the role of micro-organisms on the surface properties of titanium dioxide (anatase mineral) has been studied through zeta potential and adhesion measurements as well as the adsorption experiments. Complete characterization of both single mineral and bacteria isolated from its surface has been done using XRD, SEM, and FTIR as well as morphological and biochemical identification of bacterial isolates.

The effect of rice bran in reducing the weight of the overweight / obese individuals was carried out with the following objectives: to conduct the feeding trial for overweight / obese adults for a period of three months and assess the impact of feeding on the body composition, anthropometry and biochemical profile of the adults. Forty overweight / obese women (each 20) in the age group of 30 to 60 years with no other complications formed the basis for inclusion in the study. Assessment of body composition for the selected women was carried out using Biospace Inbody 720. Each adult was fed with 75 grams (uncooked) of rice bran pasta in the form of recipes during the lunch. Biochemical parameters among the overweight and obese adults before and after the feeding trial was analysed. Statistical analysis revealed that there was no significant change after the feeding trial. The body protein increased from 7.04 to 7.09 kg among the overweight and from 7.41 to 7.48 kg among the obese adults. Soft lean mass had increased from 33.9 to 34.05 kg in overweight adults and from 35.74 to 36.04 kg in obese adults. Body fat mass among the overweight adults reduced to 29.09 kg after the feeding trial. A high degree of positive correlation (P<0.01) was observed between fat free mass and protein, total body water, soft muscle mass and mineral among overweight and obese adults. In conclusion, the results indicate that the feeding trials with rice bran incorporated pasta at 15 per cent level for overweight and obese adults did not significantly contribute to the reduction of overweight and obesity.

In this paper experimental investigation has been carried out on kevlar/glass angle ply hybrid composites to characterize interlaminar shear strength. With the aim of determining the influence that the structure, a reinforcement type and a sort of resin exert upon the interlaminar strength. Hybrid composites are considered materials of great potential for engineering applications. One advantage of hybrid composite materials for the designer is that the properties of a composite can be controlled to a considerable extent by the choice of fibers and matrix and by adjusting the orientation of the fiber. The scope for this tailoring of the properties of the material is much greater, however, when different kinds of fiber orientations are incorporated in the same resin matrix. Three orientations viz 0?/90?, ±45?and 60?/30? were considered for studies. Mechanical properties such as interlaminar strength, interlaminar stiffness, & peak load of the hybrid composites were determined as per ASTM standards. Vacuum bagging technique was adopted for the fabrication of hybrid specimens. It was observed that orientation at 0?/90?showed significant increase in ILSS properties as compared to other orientation.

The purpose of this study was to compare various teaching methods used by university level teachers in public sector universities in Pakistan, study the common influences on choice of teaching method, and use this knowledge to enhance the quality of Instruction and therefore education in general. To encourage the student participation in the teaching learning process, their preferences of the teaching methods were also studied. The researcher used descriptive research to fulfill the requirements of the objective of the study. Major objective of the study was to compare the teaching methods favored by the teachers of various disciplines Social Sciences, Management Sciences, International Relations and Information Technology. Another objective was to study the student awareness of the methodologies used by their teachers. The sample of the study comprised of 38 teachers and 97 students from the above-mentioned departments. The instruments used by the researcher in the study were self-developed questionnaires. The questionnaires consisted of 26 items using five-point scale. The collected data was tabulated, analyzed, and interpreted in the light of the objectives of the study. From the finding of the study it was revealed that the most commonly practiced method of teaching is Lecture followed by project method. The least used method was Reflective Inquiry. There were some discrepancies among the teachers and student opinions of what teaching methods are most commonly used in the classrooms. When the teachers were asked to rank teaching methods according to the effectiveness of the method, the variables like ‘gender’ and ‘department’ did not have significant differences whereas ‘qualification’ of the teachers did. The teachers with PhD ranked Reflective Inquiry as the most effective and preferred method. The teachers with M. Phil and M.A degrees ranked Lecture method at the top.

Pectin was extracted from fruits such as orange, apple, guava and grapes using different acids. Hydrochloric acid, sulphuric acid and nitric acid were used for extraction of pectin from dried fruit pieces. The level of pectin differed in the fruits depending on the acids added during the process of extraction. Generally fruits are dried to determine the yield of pectin. Various drying methods were adopted in this study to extract pectin from above mentioned fruits. The resulting pectin content of fruits was compared with drying methods adopted.

This study compared self-regulation in 80 middle school athlete and non- athlete boys students (seventh and eighth grade). An ex post facto design was used. Statistical population comprised of all students in middle schools in, harsin, Iran, during the 2012-2013 academic year. Students selected by randomly multi-cluster sampling. The student completed the Self-Regulation Scale (SRS). Data were analyzed using analysis of variance. Differences were found between the groups on the self-regulation.

Agriculture is the major economic activity in Kenya contributing up to 24 percent of the Gross Domestic Product (GDP) (GoK, 2014). According to Odhiambo et al. (2004), agriculture is the most important sector in the Kenyan economy. This is because it provides employment opportunities, source of foreign exchange earner, and food provision besides offering linkages with the other sectors of the economy. Moreover, agriculture is among the six key sectors identified to deliver a 10 percent economic growth per annum as envisaged under the economic pillar of the Kenya Vision 2030. The country aims at promoting an innovative, commercially oriented, and modern agricultural sector (Kenya Vision 2030). Animal genetic resources are used to accommodate both short and long term benefits for improved livelihoods. Structured breeding programmes provide a key to increase production levels and product quality, increase productivity and cost efficiency, maintain genetic diversity and support the conservation and sustainable utilization of specific breeds. For sustainable breeding strategies to take place there is a need for long term planning and commitment. For conservation or improvement of a breed or population for a given purpose the choice of breeding strategy is determined by a number of factors and is giving the framework for design of more detailed breeding programmes for specific populations.

Environment monitoring system is developed to ensure the safety and convenience of an environment which needs high security. It makes use of a temperature sensor, door sensor, hall effect sensor, RFID and accelerometer. This paper aims to develop such an embedded system that monitors parameters like temperature and door status through an android app along with providing security and high temperature alerts. Over current sensing is also employed to protect the circuit by relay switching. The real time values from the sensors are monitored by LPC1754 and SMS is sent to required mobile numbers having the EMS app with the help of a GSM module. The system uses a compact circuitry built around ARM Cortex M3 LPC1754 microcontroller Programs are developed in Embedded C using the IDE Keiluvision4. JTAG is used for loading programs into Microcontroller.

Behavioral problems have remained a critical problem among girls incarcerated in rehabilitation schools. The study adopted a quasi-experimental research design with the two rehabilitation schools being randomly assigned into either treatment or control group. Quantitative method was used to collect the data through the use of questionnaire and Achenbach youth self-report (YSR) (11-18 years). Baseline data was first collected in the two sites. The data was analyzed using SPSS version 21. T-test, Chi square, Anova as well as Ancova tests were carried. The prevalence rates for depression, anxiety disorder and conduct disorder were 66.7%, 70.5% and 55% respectively. In the experimental group the study shows statistically significance difference in mean differences scores at both post-treatment one and two (p<0.001). Therefore this is an indication that MST had an impact on post treatment one and two among juvenile delinquents in experimental as opposed to control groups. The results provide significant insights into effectiveness of MST on selected behavioral problems among Juvenile girls incarcerated in rehabilitation schools.

The objective of the investigation is to mathematically simulate dynamics and vibrations of a small structure. This structure is simulating a short length bridge with 3 spans, two end fixed supports and 2 intermediate supports. The top bridge portion of the structure is subjected to a concentrated moving load simulating a vehicle moving on the bridge. Structural Analysis as regards determination of support moments and reactions is done by Matrix Method of Structural Analysis. All supports are subjected to time varying reactions. Considering intermediate supports as a single DOF system, the transient vibration response is ascertained.
