Abstract: With the continual modernization, researchers and scientists are very conscious about the environmental issues. The E-waste which is relatively recent addition to the waste stream in the form of discarded electronic and electric equipment is getting increasing attention from policy makers as the quantity being generated rising rapidly. The consumption of e-waste has been exponential in the last two decades. The developing countries are facing huge challenges in the management of e-waste which are either internally generated or imported illegally as used goods in an attempt to bridge the so-called "digital divide". E-waste contains hazardous constituents that may negatively impact the environmental and affect human health if not properly managed. On the other hand, e-waste contains up to 60 metals including platinum, gold, silver, copper, aluminium, palladium, iron and other valuable metals. Considering these two facts along with the resource management strategy has been committed to extract precious metals from Printed Circuit Board (PCB) of e-waste. In this study, Printed Circuit Board (PCB) are collected from the motherboards of waste computers and performing several reactions in a chemical lab. Al2(SO)4 has been prepared by using sulfuric acid and potassium hydro-oxide and CuSO4 prepared by using nitric acid and sulfuric acid. In this preparation process the top most priority is placed on the environment friendly issues. This study will very helpful in the proper management of e-waste and reservation of our resources which are limited.

Abstract: Goat rearing had a huge potential to emerge as a very good source of income and employment for the rural people. In spite of having potential of good economic returns, goat farmers do not earn good income from such activities mainly due to lack of training. In order to know the training needs of tribal respondents in areas of goat rearing study was undertaken in Kandhamal district of Odisha. A total no. of 60 respondent was identified from 6 villages for data collection. In goat rearing practices training needs in disease management ranked I, in which training about preventive measures to control disease, information about first aid treatment were top priorities by majority (86% and 82%) of tribal farmers respectively. Followed by housing management where training on different housing parameters (76.7%), floor type and management (70%) were top priorities. "Training Needs Assessment" (TNA) is one such method of determining training needs and identifying what training is required to fill the knowledge gap, so that the present existing situation can be known well and accordingly training need could be identified in concerned areas which will ensure that the training is addressing the actual need of the tribal farmers.

Abstract: Traditional blackboard chalk is still a prevalent teaching medium especially in most of the primary and secondary schools in the developing countries. These chalks not only pollute the classroom environments but also cause a high prevalence of chalk dust problems among teachers and young students. This article aims to identify the effects of traditional chalk dusts and to design and fabricate eco-friendly chalks. To fulfil these objectives, a cross-sectional study was carried out between October 2013 to January 2014 with a sample of 290 teachers, students and guardians in Sylhet division, Bangladesh and analyzed. The fabrication criterion of eco-friendly chalk was designed based on the identified customer requirements. Different health-related problems due to chalk dust are also identified. It is found that these fine particles of chalk dust in the classroom can exert some adverse effects on the human respiratory system, eye, skin, and hair etc. A series of lab tests and field studies were carried out to assess the performance of the fabricated chalk. The fabricated dustless chalk having a tapered cylindrical shape with a specified length and diameter offers many advantages over the traditional chalk in terms of flexibility, color, visibility, price, ease of use, etc.

Abstract: An analytical study was undertaken with the objectives of studying the concept of financial performance analysis, reviewing the current status of hotel companies in India, identifying the parameters/indicators of financial performance of hotel companies, evaluating financial performance of select hotel chains and analyzing financial statements and assessing the financial performance of select chain of hotel companies. Financial statements of five large hotel companies from India were analyzed for a period of six years. Four of the key performance factors showed much lesser than expected growth to be called as a steady growth. For Operating Revenue, Total Revenue, Gross Margin and EBIDTA the actuals are significantly lower than the expected performance at a CAGR of 10%. However, in case of performance factors like PBT, NP, EPS and Dividend the actual average performance is significantly better than the expected performance at a CAGR of 10%. Both the key parameters taken for financial health, namely, fixed assets and net-worth have shown significantly low actual values than the expected reasonable growth of 10% CAGR to lend some steadiness to the financial health of the Hotels. The industry on an overall basis has not shown a steady performance given the weak CAGRS on Revenue, Gross Margin and EBIDTA. After six years the operating revenue in FY 2018/19 stood at Rs.5004.17 crores from Rs.4560.60 crores in the year 2013/14. Even if we apply a CAGR of 5% the expected revenue by the end of 2018/19 was Rs.6111.64 crores. Market is a problem for the Hotel Industry. At the same time profitability has shown a better performance as compared to the top line. In fact, the year 2018/19 has recorded the highest NPs for all the six years. This is an encouraging sign and it can be expected that the industry will do better in the years to come. This article presents the findings and conclusions from the study.

Abstract: With advancement in technology and production of nanosized particles, access and more importantly cost of nanoparticles have come down. This gives an exciting opportunity to tackle the strict regulations for emissons being in place which poses an urgent need to reduce emissons of not only new vehicles but of existing vehicles with as little external modification of the engine as required. Not a lot of extensive work has been conducted in terms of emissons, combustion and performance characteristics of fuels mixed with metallic nanosized powders. Zinc oxide is one such exciting nanoparticle because of its properties such as improvement of heat transfer rate, flash point, fire point, ability to store energy in it crevices and mass diffusivity, when dispersed in any fluid medium. And also it increases catalytic properties and provided higher surface to volume ratio. In the present work the Biodiesel derived from waste cooking oil (WCO) has been employed as fuel along with 80 ppm ZnO and is considered for investigation. A Kirloskar made TV2 diesel engine has been employed to conduct the experiment at varied load. In this experiment Diesel has been considered as baseline reading and two other fuels, that is Biodiesel and Biodiesel+80ppm of ZnO has been considered for comparison purpose. The engine has been run from 0% to 100% load using the 3 fuels and the results have been evaluated, tabulated and plotted on graphs for discussion. From the results it is revealed that the BTE is increased by nearly 4% and BSFC has reduced by 9% thus showing that the performance of the engine is improved .The emissions of CO, NOx and PM has reduced and especially CO has reduced by nearly 30%.There is also improvement of combustion with the HRR increasing by nearly 11% and introduction of ignition delay. Thus by employing this additive the emissons are decreased without penalizing the performance and combustion characteristics

Abstract: The garden cress seeds were subjected to dry roasting process. Changes in chemical and nutritional quality properties after roasting process were investigated. The results showed that cress seeds are good source of nutrients, such as oil, protein, carbohydrates, in addition to β-carotene, lycopene, phenolic and flavonoids compounds. Chemical composition of the studied seeds flour was significantly (P<0.05) affected by the roasting process. The roasting process resulted in a decrease in moisture, protein, vitamin C contents; however, the content of ash, oil, lycopene and total flavonoids was increased. The abundant minerals in the unprocessed seed flour were phosphorus and calcium. Whereas the contents of magnesium increased after roasting, iron content was decreased. Moreover, the flour obtained from seeds after roasting process was used to manufacture water biscuits; and the overall acceptability of these biscuits did not show significant differences between these biscuits and control (100% wheat flour). Indeed, it could be suggested that dry roasting can be used as processing method for production of roasted cress seeds flour with good edible and nutritional quality to be used as dietary supplement.
