In this complex society of today where experiences are innumerable and varied it is not at all possible to present every situation in its original colors hence the opportunities for learning by actual experiences always are not at all possible. It is only through the use of proper audio visual aids that the life situation can be trough in the class room by an enlightened teacher in their simplest form and representing the original to the highest point of similarity which is totally absent in the verbal or lecture method. In the presence of audio aids the attention is attracted interest roused and suitable atmosphere for proper understanding is automatically created, but in the existing traditional method greater efforts are to be made in order to achieve the aforesaid essential requisite. Inspire of the best and sincere efforts on the side of the teacher the net effect as regards under standing or learning in general is quite negligible.

Transition behavior from monolayer on the water surface to single particle layer of ternary comb copolymer containing carbazole ring have investigated by surface pressure-area isotherm, atomic force microscopy, X-ray diffraction. This polymer monolayer is able to form the “polymer nanosheet” with amorphous layers and strong interaction between main-chains fabricated by a Langmuir-Blodgett (LB) technique. Further, single particle layer is able to form the multi-particle layered organization of “polymer nanosphere” by LB method. This ternary comb copolymer synthesized by radical copolymerization with hydrogenated and fluorinated long-chain vinyl compounds. Poly(N-vinylcarbazole) homopolymer formed single particle layer on the water surface after spreading, immediately. Spontaneous “particulation” behavior is accelerated by incorporation of carbazole units in ternary copolymer films.Monolayer of these copolymers on the water surface formed below 10 mN m–1, and this monolayer transited to single particle layer above 15 mN m–1.

Bangladesh is the eighth populous country in the world with the highest population density and a vast majority of its population, who are living in villages and small towns, are deprived of power. Recently some steps are being taken by the Government of Bangladesh (GoB) to bring those people under electrification who are in remote inaccessible unelectrified area where grid expansion is expensive and it is being done by encouraging them to use renewable energy such as: Solar photovoltaic, Solar thermal power, Wind power, Biogas, Mini- Hydro etc for electricity generation in stand-alone system. But the high installation and maintenance cost of these renewable energy based power generation in standalone system are becoming the main hindrances to the village people to afford it. Though some financial helps are provided from government and some NGOs, but those are not enough and only a few people get these privileges. That’s why the potentiality of renewable energy couldn’t be used in an effective way. The objective of this paper is to present an alternative and - from our point of view – more realistic aspect of using renewable energy effectively in the reliable energy supply. This paper will discuss about an idea of cost effective community based micro off-grid power system which will emphasize on using Renewable Energy Technologies (RETs) like utilizing Biogas for power generation. Furthermore, this paper will also visualize as to how this micro off-grid system can be implemented in those villages and small towns which are currently detached from electricity and it can be done by dividing each village or town into small communities and bringing them under electrification. Many factors, such as technology costs and investment analysis, benefit-cost ratio, payback period and available potentials have been incorporated in order to fulfill this task.

Forage crops play an important role in removing P and N from poultry litter-amended soils there byminimizing environmental pollution. A three year study was conducted at Crossville, AL to compare dry matter yield and total P and N removal efficiencies by forage crops from a poultry litter-amended soil. Forage crops including alfalfa (Medicago sativa, L.), rye (Secalecereale, L.), corn (Zea mays, L.), sorghum-sudangrass (Sorghum bicolor, L.) cv. Unigraze II, tall fescue (Festucaarundinacea, L.) cv. KY31, and Russell bermudagrass (Cynodondactylon, L.) were investigated. The soil type at the site was a Hartsells fine sandy loam (fine-loamy, siliceous, thermic TypicHapludults).The highest dry matter yield in 2001 was observed with sorghum-sudangrass and in 2002 and 2003 it was observed with Russell bermudagrass, respectively. In 2001, the lowest dry matter yield was observed with alfalfa, in 2002 it was observed with corn, and in 2003 it was observed with sorghum-sudangrass, alfalfa, and Russell bermudagrass, respectively. Sorghum-sudangrass showed the highest N uptake in 2001, alfalfa and Russell bermudagrass showed the highest N uptake in 2002 and 2003, respectively. Tall fescue showed the highest P uptake in the three-year study. Russell bermudagrass appears to be the most effective forage crop for removal of N and tall fescue for the removal of P from soils amended with poultry litter.

This paper offers an alternative oppositional reading against the obvious, dominant taken-for-granted codes of scopophilia by which Aaron Siskind’s “Harlem” photograph is interpreted. The paper draws primarily on the works of French thinkers Roland Barthes and Jean Baudrillard to make the case that the nudity of the Black woman evokes a false sexual pathos and heigthens the fetishization of her body.

The paper will discuss the impact that education technology has on the teacher-student experience. Does learning really take place or has the educator been removed from the teaching experience and environment and does this impact on the learning environment. The study will conclude that technology can enhance the teacher-student experience; although the educator-student learning experience cannot be replaced by technology, due to human and social elements which technology lacks. Education technology does not have interpersonal interaction and an increase in technology can lead to less interest within teacher-student relations. Communication constitutes of 80% of verbal communication through language, while 20 percent is nonverbal such as writing. The various types of education technology used in the teaching process falls into the 20 percent category which is nonverbal and can be ineffective and based on research if used alone is not the most effective tool for teaching and learning.

Emotional intelligence currently growing attention and earn a spot in the form of psychological studies. Emotional intelligence detected can influence employee commitment in an organization. The theoretical solutions are simply not able to unlock the psychological issues in organizations because it is closely linked to affective, cognitive and human behavior in public sector. In this study, the issues in the workplace are referring to emotional intelligence, self-esteem and commitment of employees. The specific purpose of this study was to test the impact of emotional intelligence among employees whether it able or unable to influence a commitment to the organization through employee self-esteem factor. A total of 196 civil servants in the Local Authority (LA) have been selected as respondents. Measurement tools that are used in the data lump is Emotion Intelligence Self-Description Inventory (EISDI), Rosenberg Self-Esteem Scale (RSES) and the Employee Commitment Survey Revised Version (ECS).The data was then analyzed using hierarchical regression analysis. The findings show that emotional intelligence and four dimensions of emotional intelligence have a direct impact on organizational commitment. In fact, the emotional intelligence and dimensions also has an indirect effect on organizational commitment when self-esteem as mediator factor is controlled. Employee self-esteem later found to function as a partly mediator that affecting the relationship between overall emotional intelligence and four dimensions of emotional intelligence with organizational commitment. The most important findings are found emotional intelligence dimension among employees are able to become more relevant with the increasing availability of commitment of employee when there was the element of self-esteem as a mediator factor.

Introduction: In preliminary studies, we have determined that there is a high adhesion and usefulnesswith the use of virtual spaces (TLVE) in Anatomy students as a teaching resource which is supplemental to practical assignments (PA) of the subject. The population on which studies have been conducted showed an important heterogeneity regarding the social-economic characteristics of participants.Purpose: To assess the impact of the social-economic factor of students in the parameters of use, adhesion and performance in the virtual space, with specification of the teaching techniques used. Materials and Methods: Observational, retrospective and transversal study on parameters of use and performance with a TLVE in a cohort of 309 students. Results have been divided by areas of the subject, statistical parameters have been applied (descriptive and inferential)and they were correlated with the above- referenced data of social-economic characteristics. The work complies with applicable ethical-legal regulations. Results: The working hours of students were correlated with the use of the TLVE (number of inclusions/dayr2=0.75and weekr2=0.78)and performance in clinical-surgical cases was proportional to the loggingtime(r2=0.75). Conclusions: Working activity together with university studies and, specially, the time of weekly working activity, were determining factors in the performance obtained in the virtual space and in the parameters of use of the technological resource. Key terms: Anatomy. Teaching. Social-economic factor. Teaching and learning virtual space.

The article gives an account of the results of construction of mathematical modeling of the wagon rolling down the hump under the impact of gravity and head wind aerodynamic drag forces that made it possible to derive analytical formulas for determining wagon speed and traversed distance during rolling down the first profile hump section. The results of the analytical research of dynamics of wagon rolling down the first high-speed hump section can be used for all the rest hump sections taking into account the specifics of braking forces on these sections. The novelty of the derived formulas of wagon speed rolling down high-speed hump section is in presenting head wind aerodynamic drag force as depending on the wagon speed rolling down hump profile and speed and direction of air flow with proper allowance for resistance forces arising during wagon movement.

This study though limited due to poor attitude on the part of the respondents as regards to releasing some data that would have been helpful, was still able to investigate the effect of maritime tanker accidents on coastal areas in Nigeria, with a case study of Bayelsa and Rivers State. Five hypothesis were designed for this study, the study focused on the affect of oil tanker accidents around the Nigeria coastal environment (Bayelsa and Rivers State). With emphasis on the scope of work essentially, data were collected through the administration of questionnaires to the selected people connected with tanker and environmental industry in Nigeria. The analysis of the collected data was carried out with a descriptive statistical tool like the simple percentage and pie charts which hypothesis specified were tested using chisquares test statistical tool. Result obtained shows that the major cause of marine tankers accident in Nigeria is as a result of human factor errors and this human error has greatly led to the negative effects, the tanker accidents have posed in the coastal environment (Bayelsa and Rivers State) in Nigeria. The safety practical level of the tanker industry in Nigeria had lowered drastically which for the need for proper training and certification of Nigeria oil tanker operators the level of emergence response is relatively poor as compared to other nations with massive oil maritime transport activities. Finally, the Nigerian government should fully empower and support the maritime agencies in checkmating cases of maritime pollution and environment depredation and not boycott corners process thereby sacrificing the standards for effective and efficient maritime operations in Nigeria. Recommendation were made towards the elimination of tanker accidents and the enhancement of the Nigerian coastal environment, which needed government to formulate and promulgate laws which have stringent penalties for violators of the Pollution Act. Also national authorit
