Smart class is an initiative of Educomp, which is rapidly transforming the way teachers teach and students learn in colleges with innovative and meaningful use of technology. Students learn difficult and abstract curriculum concepts watching highly engaging visuals and animations. This makes learning an enjoyable experience of students while improving their overall academic performance in college. Smart class also enables teachers to assess and evaluate the learning achieved by their students in class with an innovative assessment technology smart assessment system designed by Educomp. Quality education is an essential requisite in today’s competitive environment. Technology has affected us in every aspect. This paper discusses the smart classes as a modernized method of education in Indian education scenario which provides quality education to students by helping them in better concept formation, concept elaboration, improvement in reading skills and academic achievement. Technology benefitted us in every aspect of our life right from communication to education. In ancient days students were taught in a Gurukul where they were taught by the gurus. But this system was replaced by modernized culture. New methods of teaching have been introduced which is known as smart class. It uses instructional material, 3D animated modules and videos ,activity based learning. Now the students are thrilled at this concept of innovation and interactive teaching-learning process.Keywords: Smart Class, Chalk &Talk, Attitude, Technology, Multimedia etc.
Food hygiene practices among food handlers has gained noticeable importance in each step of the food chain from the production to preparation and serving of the food in developed and developing countries including Bangladesh. The chances of food contamination largely depend on the knowledge of food handlers and on their food hygiene practices.This study conducted to determine food hygiene knowledge and practice among food handlers. This is a cross sectional descriptive study carried out on 84 food handlers at five selected middle class restaurants Sylhet, Bangladesh. All cleaner, waiter and cooker were included in this study. Demographic data, knowledge and practice of food handlers were analyzed. The total number of food handlers during the study period showed that most of the food handlers (50%) were the age range of 10- 20 years of which majority 81.0% were male and 49% had only primary level of education. Food hygiene practices elaborated significant differences observed by age, gender, education and occupational status. Most of the food handlers had basic knowledge on hand washing m±sd=2.77±.546 and 86.9% had the knowledge on sources of food contamination, m±sd=2.83±.461. Respondents mostly put the never practice on gloves and mean score is 2.26±.1.804. The out of total respondents in this study had average knowledge m±sd=2.15±.668, (71.6%) that was significantly associated with age, marital status, occupation and monthly income. The average Food hygiene practices m±sd=3.88±1.059, (77.6%) also revealed that there were statistically significant relationship with most of socio demographic variables. Knowledge and practice on food hygiene among food handlers in local restaurants was found good and also a positive association among the variables suggests that the knowledge regarding food hygiene practice is increased by training on measures and its importance in the education of food hygiene which increases knowledge and practice.Keywords: Awareness, knowledge, Personal practice, Wholesome food.
Non-target effect of pesticide on soil organisms is an important area of ecotoxicology, due to their roles in ecosystem sustainability. Thus, the effects of an organochlorine (endosulfan) and a synthetic pyrethroid (cypermethrin) pesticide formulation on soils’ culturable microbial population were investigated. The study was carried out on loamy sand soil sample types collected from Ondo State, Forest Reserve, Owena, Nigeria. Pesticide application rates in the range of half of the normal field rate (0.5FR), the normal field rate (FR), two times the normal field rate (2FR), four times the normal field rate (4FR) and eight times the normal field rate (8FR) were applied to the soil microcosm design in the laboratory; while the untreated soil serve as control. The experiment set up was completely randomized in three replicates and soil samples were collected from each of the set up at 5 days interval over 35 days period of exposure for analysis. The pour plate technique was used for the enumeration of bacterial and fungal colonies on nutrient agar and potato dextrose agar respectively. The results indicated that both pesticides had effects on the population of bacterial and fungal counts of the soil samples with significant (p < 0.05) adverse effect observed at the treatment rate above the normal field application rate. At lower application rates (0.5FR, FR and 2FR), temporary inhibitory effect on bacterial and fungal population were observed. The progressive increase in inhibitory effect with corresponding increase in concentration of endosulfan and cypermethrin were noticed.Keywords: Organochlorine pesticide, Synthetic pyrethroid, Endosulfan, Cypermethrin.
The vectoring performance of shock vector control was investigated for a two-dimensional supersonic nozzle designed using the method of characteristics with injector shape being slot-shaped (rectangular). Unlike a conical nozzle, the method of characteristics nozzle has a divergence angle that varies which affects the dynamics of the flow at the exit of the nozzle. The nozzle was designed with NPRD = 9 and the injector was fixed and positioned at 80% of the divergence length with the injection angle being right angles to the nozzle wall. This study is focused on the effects of mass flow ratio on shock vector control. The mass flow ratio was controlled by varying the stagnation pressure ratios. Schlieren imaging with a single mirror coincident system was used to visualize the flow field in the nozzle. Experiments were performed with air as both primary and secondary fluid for a range of primary and secondary pressures. The data obtained were compared with numerical simulations which were run using different turbulence models, with Sparlat-Allmaras one equation and standard k-? model, under the same experimental conditions. The results obtained using the Sparlat-Allmaras one equation model were found to closely match with that of the experiments. On increasing the mass flow ratio, the deflection or vectoring angles were observed to be increasing but up to a certain maximum. The maximum experimental deflection angle achieved was approximately 120 and vectoring coefficient being 2.383. For flow cases where reattachment occurs, downstream of the injector, the nozzle designed using the method of characteristics can, yet, direct the flow parallel to the axis, hence producing a lesser opposing moment than in case of a conical nozzle.Keywords: fluidic thrust vectoring, shock vector control, method of characteristics, secondary transverse injection, transverse gas injection.
In India the most commonly used mode of transport is by roads, annually India losses 3% of its GDP to road accidents which is over $58,000 million in terms of value. So, the safety is considered as the most important aspect in terms of Designing, Construction, Maintenance. Traffic is recognized as the major growing public health problem in India.
This study aims to develop a model for prediction of crash frequency using recent mathematical techniques. Thus, crash data of National Highway 65 from Hyderabad to Vijayawada is been considered from year 2013 to 2018. Model calibration is done in soft computing technique ANNin MATLABusing dependent parameter as crash count per segment per year and independent parameters as geometric characteristics like change in curvature, gradient, degree of curvature, and average traffic volume is considered along with the speed. From which the three network gives the best output results.Keywords: Crash modeling, ANN, Levenberg -Marguardt (LM) and Bayesian Regulation (BR).
