The main objective of the current proposed work is to study the technical, environmental and economical feasibility of the implantation of co firing technology in a Biomass power plant with pulverised low rank coal. Co-firing biomass and coal increases the use of sustainable fuels without large capital investments, and takes advantage of the high efficiencies obtainable in coal-fired power plants. Fuel diversity is another advantage of biomass/coal co-firing. Co-firing reduces the need for a constant supply of biomass required as in a biomass power plant, and is a viable way to decrease the emissions of greenhouse gases and other pollutants from power-generating facilities. As a result, using renewable and sustainable energy resources, such as biomass co-firing, for electricity production exhibits great potential in the near future. The use of dedicated biomass feed stocks for electricity generation could help to reduce the accumulation of greenhouse gases. This work focuses on minimization of overall unit cost of electricity with a maximum performance.

The purpose of this paper is to understand undergraduate students’ perception of the Final Year Project’s supervisory process. A survey was carried out to elicit the students’ views to gain an insight into their experience during the supervision process. The sample consisted of 91 students in a private university in Malaysia. The participants’ responses were analyzed according to the research questions and recurring themes. Only these factors are affected by gender of students: area of expertise of supervisors, timely feedback, duration of the research project and the number of meetings with supervisors. The implications of these findings are discussed. A number of implications were derived for theory, practice, and further research.

In recent years, coincide with population growth and industrial expansion, in many countries in the world, Extract water of underground sources expanded and annual withdrawal of ground water is higher than the annual feeding. This means extracting and using the water in layers that has been saved over thousands of years in the underground. Consequently groundwater levels in the area will be extracted every day and eventually drop where the water will not exist. While proper management and control of these resources will eliminate the problems of drop in water level. One way to managing groundwater resources is artificial recharge of groundwater and determine suitable locations for these purpose. growth and development trend of Mashhad city and excessive Extracting of ground water in recent years, has been essential groundwater resources management strategy in the region more than ever implied. The purpose of this study is Zoning Mashhad watershed for artificial recharge of underground aquifers using TOPSIS Model and GIS technique. TOPSIS algorithm is a Multi Criteria Decision Making, a type of compensatory model and an adaptable subgroup with strong ability to solve multi alternative problems because of having ability to overlap indicators in weak and power points . In this model, if quantitative criteria can change in to qualitative criteria, qualitative criteria can be used besides quantitative criteria. In aforementioned model, it is supposed that each indicator and criterion has steady increasing and decreasing utility in decision making matrix; it means if criteria gain more positive amount, they will be more appropriate, on the contrary the more negative amount, the less appropriate. The result and findings of different studies show that in TOPSIS method, zone 3 with (0/669) point promotes in first rank among 5 studied zones and thus it is the most appropriate zone to establish the proper area for artificial recharge of underground aquifers , in contrast zone 1 with (0/302) point goes down to the last rank and so it isn`t suitable for establishing damp and zones (4,2,5) with (0/650, 0/450, 0/325) points are located in next ranks.

Waste plastics are one of the most promising resources for fuel production because of its high heat of combustion and due to the increasing availability in local communities. Unlike paper and wood, plastics do not absorb much moisture and the water content of plastics is far lower than the water content of biomass such as crops and kitchen wastes. The conversion methods of waste plastics into fuel depend on the types of plastics to be targeted and the properties of other wastes that might be used in the process. Additionally the effective conversion requires appropriate technologies to be selected according to local economic, environmental, social and technical characteristics. In general, the conversion of waste plastic into fuel requires feedstocks which are non-hazardous and combustible. In particular each type of waste plastic conversion method has its own suitable feedstock. The composition of the plastics used as feedstock may be very different and some plastic articles might contain undesirable substances (e.g. additives such as flame-retardants containing bromine and antimony compounds or plastics containing nitrogen, halogens, sulfur or any other hazardous substances) which pose potential risks to humans and to the environment. Pyrolysis is the thermal disintegration of carbonaceous material in oxygen-starved atmosphere. When optimized, the most likely compounds formed are methane, carbon monoxide, hydrogen carbon dioxide and water molecules.the yields of different products depend very much on the process variables. The pyrolytic oil can be blended with the conventional liquid fuels. The pyrolytic waste disposal will also mitigate the problems of environmental pollution.

A study on women’s involvement and their training needs in rice cultivation and in Chatra district of Jharkhand was studied in five selected villages one each from five selected blocks i.e. Kunda, Partappur, Simariya, Tandwa and Hunterganj covering 250 respondents. Results indicated that harvesting was the activity in which farm women were mostly involved followed by transplanting, weeding, seed selection and treatment, sowing and nursery raising and seed grain storage with weighted mean scores of 2.56, 2.57, 2.38, 2.25, 2.18, 1.96 and 1.37 respectively. Plant protection was rated first training need followed by seed and grain storage, land preparation, seed selection and treatment and sowing and nursery raising with weighted mean scores of 2.36, 2.24, 2.20, 2.08, 2.04, 2.01 respectively.

The same responsibility to educate Indonesian young generationlies on both private and public Universities. However, due to the rapid growth of both Universities,tighter and higher competition has been found. The lack of students entering private Universities (PTS) have made many of them collapsed.Therefore, to face the tight competition, PTS need to concern on some particular strategies to improve the number of students who enroll PTS. One of the strategies is by improving the academic performance.This study was to develop an optimalization model to improve academic performance in PTS through Total Quality Management (TQM) Development in many PTS at Central Java. The data were obtained from observation, questionnaire and in-depth formal and informal interviews to the lectures and the head of PTS. The data were gathered purposively using sequenced mixed methods. The study found thatthere was weak correlation between organizational culture, employee motivation, job satisfaction, academic performance and TQM in PTS at Central Java. Academic performance in PTS was stillworst with the index value of 3.94. Meanwhile, TQM indicated the index valueof 3.99 which was in medium to good category. As a matter of fact, it was necessary to build organizational culture, work motivation, job satisfaction to optimize academic performance also there was necessary to be develop TQM in PTS. This condition would be possibly happened along with the high commitment of the leaders, academic staffs, as well as continuous monitoring and evaluation program to achieve stakeholders’ satisfaction.

The photocatalytic activity was studied under UV light using AC-Cd/TiO2 prepared via precipitation method and characterized by powder X-ray diffraction (XRD) , high resolution scanning electron micrographs (HR-SEM) with energy dispersive X-ray analysis (EDX), photoluminescence (PL) and Fourier transform Raman analysis (FT-RAMAN). The enhanced photo catalytic activity of the AC-Cd/TiO2 is demonstrated through photodegradation of methylene blue under UV light radiation at 365 nm. The mechanism of photocatalytic effect of AC-Cd/TiO2 Nano composite material has been discussed Further its antibacterial activity against two gram positive and two gram negative bacterial strain is studied.

Opacity, The most serious mystery and elegant poetic technique, which utilizes the mechanical poets, his poems have Most art, and to make a speech addressing Confidential, and Surprisingly violent and Brainstorming have used. Opacity, which is a trick of language in literature, rhetoric in Arabic and Persian, have been taken into consideration. In this research, based on the method of analysis - descriptive, and utilization of resources in this area to explore the aesthetic, opacity, Arabic Rhetoric deals. Results indicate that, as discussed in Arabic literature, opacity, and various types of attention, and in the lyrics of his rhetorical works, the various statements that have been, and in this context it is interesting to note the range of rhetorical opacity in Arabic literature, the less wide, had Persian literature, and the most important opacity can be single, fit, beverages, expression, and Well suited pointed out.

In this paper we review the security attacks on mobile adhoc networks like black hole, grey hole attacks etc. the study on security attacks and intrusion detection system has led us to illustrate some of the particular security issues.

Retail outlet plays an important role in today’s context. Earlier, only some selected retail outlets were found with an exclusive range of products enjoying monopoly status. Now the trend has been changed and many sophisticated Retail shops and Mall with wide variety of products are seen everywhere. Maintaining Service quality is an inevitable tool for those retail outlets as it acts as a precursor for customer satisfaction and Loyalty. In India there have been a great successful brand both national as well as international brands and again it has been realize that brands are sustaining power to stay in the competitions. If we defined the customer satisfaction we can say “a qualitative measure of performance as defined by customer, which meet their basic requirements and standard.” Customer satisfaction is defined as “measure or determination that a product or services meet a customer’s expectation, considering requirement of both quality and service.” This paper attempts to analyze and compare the perceptions of customers towards service quality of reputed shopping Malls in Visakhapatnam District with a sample of 50 each from three retail outlets namely CMR shopping Mall, Big Bazar and Spencer Shopping Mall and totally of 150 respondents from the population selected randomly. Data from structured questionnaire was analyzed by using Percentage analysis, ANOVA and four point Likert scale.
