In this work, the experimental and theoretical vibrational spectra of N,N-dimethyl-m-anisidine (NNDMA, C9H13NO) (3-methoxy-N,N-dimethylaniline) were studied FT-IR and FT-Raman spectra of NNDMA in the liquid phase have been recorded in the region 4000–400 cm?1 and 3500–50 cm?1, respectively. The structural and spectroscopic data of the molecule in the ground state have been calculated by using density functional method (B3LYP) with the 6-31G and 6-311++G(d) basis sets. The complete assignments were performed on the basis of the potential energy distribution (PED) of the vibrational modes, calculated with scaled quantum mechanics (SQM) method. The calculated HOMO and LUMO energies show that charge transfer occur in the molecule. Besides, molecular electrostatic potential (MEP) and thermodynamic properties were performed. The other molecular properties like Mulliken population analysis and polarizabilities of NNDMA were reported.

The buildings situated on hill slopes in earthquake prone areas are generally irregular, torsionally coupled & hence, susceptible to serve damage when affected by earthquake ground motion. Such buildings have mass & stiffness varying along the vertical & horizontal planes, resulting the center of mass & center of rigidity do not coincide on various floors, hence they demand torsional analysis, in addition to lateral forces under the action of earthquakes. These unsymmetrical buildings require great attention in the analysis & design. Analysis of hill buildings is somewhat different than the buildings on leveled ground, since the column of hill building rests at different levels on the slope. The shorter column attracts more forces & undergoes damage, when subjected to earthquakes.

India has the highest number of road accident casualties in the world. Out of 0.5 million accidents occurring every year around 0.2 million people lose their precious life. Most of the people die because of lack of proper first aid and immediate back up services. The information about the accident does not reach to ambulance service very soon after occurrence of the accident. To overcome this problem Accident Recovery System is simulated where a sensor is installed in the car which detects an accident and sends a message to the Administrator. Admin can immediately request for backup service and also alert the cars behind the accident location. Various sensors combined together gives us more faster and reliable detection of accidents on highways through autonomous units on the edge of the road (Road Support Units).The sensors in the car tend to detect any accident that has occurred to the car and send a message to the administrator with the help of Road Support Units which helps a car to be connected in the network. The simulation of the model is done with the help of NetLogo.

SOLECKSHAW, a motor assisted pedal driven three wheeled vehicle, was developed by CSIR-CMERI in 2008-09, under the recent CSIR vision, CSIR-800, aimed at empowering 800 million Indians, who belong to the underprivileged class of society in our country, by way of S&T intervention. Rear wheels of SOLECKSHAW are driven by manual power and front wheel is driven by brushless DC (BLDC) electric hub motor, leading to driving comfort of the driver. Once the product was developed and on road trial was successful, the technology was transferred to a few Indian Industries. It is found that the users of SOLECKSHAW are financially handicapped and not exposed to modern science and technology, which is a major hindrance in deploying this technology. Thus this market seeding project was taken up to make these users (rickshaw pullers) empowered through extra effort and financial facilitation. The main objective of this project was deployment of SOLECKSHAW technology on a large scale in a faster mode, to ensure its acceptability in the society. Based on the user’s feedback and ready availability of interested “Operator” in the form of either NGO or a start-up tourism company, Soleckshaws have been successfully implemented on road in different cities of the country.

Now a day, global warming has induced changes in precipitation in different regions of the world. Bangladesh is recently experiencing climate change impact related to hazards like cyclone, flood, draught etc. Climate variable like rainfall is the most important parameter which is linked with agricultural aspects too. Most of the rain occurred during monsoon period in Bangladesh. The study on rainfall trend over the country has done using observed station data of Rainfall (In-situ) collected from Bangladesh Meteorological Department (BMD) .These data have been analyzed based on annual and seasonal variation in Bangladesh for last 6 decades. A set of analysis has been carried out for this study. Linear trend lines show the rainfall trend over Bangladesh which is not very significant. The annual and monsoon rainfall is found in decreasing trend in recent times (1981-2010) whereas in increasing trend during the period of 1951-2011. The time series statistical analysis of this study will provide information about annual and seasonal mean total rainfall and rainfall variation over the country for different decades, as well as the rainfall trend in different divisions of Bangladesh in different times. The result of this study will help the policy makers to take necessary steps and measure in different sectors like disaster management, agricultural production, drought mitigation, flood control etc. and to act against the adverse impact of climate change. In this paper, annual, seasonal and divisional rainfall variability and trend analysis over Bangladesh will be discussed.

The Cu(II) , Co(II), Ni(II), Zn(II), Cd(II), Hg(II), Mn(II) and Fe(III) complexes of Schiff base 6-bromo-N’-(1-(5-chloro-2-hydroxyphenyl)ethylidine)-2-oxo-2H-chromen -3-carbohydrazide has been synthesized and characterized by various spectral techniques. The complexes were prepared by reacting the ligand and metal chloride of Cu(II), Co(II), Ni(II), Zn(II), Cd(II), Hg(II), Mn(II) and Fe(III) in ethanol to get a series of mononuclear complexes. The complexes were characterized by CHN analysis, conductivity measurements, magnetic susceptibility, IR, NMR, ESR, UV-Vis and X-ray Powder diffraction studies. By these spectral studies it is found that Cu(II), Co(II), Ni(II), Mn(II) and Fe(III) complexes have exhibited octahedral geometry where as the other Zn(II), Cd(II), and Hg(II), complexes have exhibited square pyramidal geometry. The ligand and its metal complexes have been screened for their antimicrobial activities. The prepared ligand shows low activity and its metal complexes shows moderate to good activity.

This paper proposes a new Tabu Search Enhanced Artificial Bee Colony (TSEABC) algorithm that integrates the concepts of Tabu Search (TS) and Artificial Bee Colony (ABC) techniques. The proposed algorithm is applied to solve Economic Load Dispatch(ELD) problems considering of prohibited operating zones and ramp rate limits of thermal units, capacity limits and power balance constraints. In the proposed TSEABC algorithm, the best attributes of both TS and ABC are utilized, and it is capable of finding the better optimal solution for the combinatorial optimization problems. For validating the proposed algorithm, it has been tested on the standard three, six and fifteen unit test systems. The comparison of results show that the proposed TSEABC algorithm is well suitable for solving non-linear economic dispatch problems, and it is doing better than the EP, PSO and other modern metaheuristic optimization methods reported in the recent literatures.

The study was conducted to examine secondary school teachers’ perception of personnel management functions and their job performance in Ikom Education Zone of Cross River State, Nigeria. The study utilised two objective, research questions and hypotheses and the ex-post facto research design was adopted for the study. The study population comprised all public secondary school teachers in Ikom Education Zone of Cross River State. Data obtained from the Ministry of Education, Calabar which stood at 15, 972 and a sample of 529 teachers were used and the study with stratified random sampling technique a well validated researcher’s developed instrument titled School Teachers’ Perception of Personnel Management Functions and their Job Performance Questionnaire (STPPMFJPQ) was adopted for data collection. The instrument was scrutinized for correction by expert validation the Department of Educational Foundations and Administration, and two from Measurement and Evaluation, all from the Cross River University of Technology, Calabar. The face validity was also determined using the split half reliability method to determine the internal consistency which ranged from .76 to .84 accordingly and the data was analysed using descriptive (mean and standard deviation), and inferential statistical analysis (One-Way Analysis of Variance). The major findings revealed that there is a significant influence of staff recruitment on secondary school teachers’ job performance. Also, staff development programmes do significantly influence secondary school teachers’ job performance. It was recommended among others that the government should endeavor to recruit competent teachers in schools, so as to promote quality and standard in the teaching profession this will further enhanced teachers’ job performance in Ikom Education Zone.

Teaching is a noble concept, and it is highly respected in the society. It is a social process that is basically derived from philosophy despite the fact that Philosophy is always confused with a farfetched idea or a metaphysical conceit, however, it is very simple to understand. There is no denying the fact that it is not every body’s cup of tea. Yet everyone has a specific philosophy that determines his course of action in life. In other words, every human being has a philosophy which he has and tries to live with. Teachers are supposed to do some noble work in order to bring societal change to deal with the modern need of the fast changing time. It will simply not be possible unless they possess some noble thoughts. These ides or thoughts are nothing but their philosophy. Philosophy of life can further be categorized into sub philosophies. Philosophy of teaching is one of them. In educational system, many educational philosophers are taught, and each future teacher or practicing teacher has a liking for a particular philosopher or educationist. In sum, philosophy of teaching determines every activity or action of a teacher starting from objectives, discipline, teaching style, management, curriculum, evaluation etc. Teaching of English is perhaps more important than any other subject because it plays the role of international communication, global business, medium of instruction, examination and language of science-technology and medicine. Therefore, the teachers of English language must have social values and incorporate philosophical considerations while teaching the target learners.

This paper investigates the efficacy of Newmark’s semantic and communicative translation methods in teaching vocabulary to elementary Iranian EFL learners. To do so, based on the true experimental method, a pretest posttest procedure was administered. Analysis of the results in the posttest revealed significant differences between communicative group and semantic group, on the one hand, and between these groups and the control group, on the other hand. The results showed that though both communicative and semantic translation methods enhanced vocabulary development of the learners, communicative translation method seemed to be more effective than the semantic one. That is, communicative group outperformed the other two groups significantly. Hence, it was concluded that the contribution of communicative translation method in teaching vocabulary items to elementary Iranian EFL students led to a higher level of vocabulary improvement. The study can also be helpful in establishment of Persian equivalents in teaching vocabulary in EFL settings.
