Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Technical Report from the year 2014 in the subject Veterinary medicine, grade: Phd, , course: Environmental Biology, language: English, abstract: Existing government line department services are mainly focused upon providing veterinary service to hardly 11 to 14% livestock of the province. In order to narrow the existing gape in the provision of animal health care services and to cater farmer's need for improved livestock production technologies there is need to develop community based extension services. Good results with such approach were achieved by Mercy Crop International in Afghanistan and by European Economic Commission (EEC) & Asian Development Bank (ADB) assisted Balochistan livestock department projects in some parts of the province. Since past decade there has been gradual shift in provision of animal health services towards community manage extension services because of UN agencies and other international donors started involving communities in this task. This concept eventually leads to evolution of professionally trained sustainable service providers. With the liberalization of animal health services in Balochistan , community livestock extension workers (CLEWS) have be come an important alternative animal health delivery channel in the Balochistan's marginal areas.Lack of empathy between the extension staff , particularly the urban based veterinary officers and ordinary rural people and a poor understanding by the technically trained extension workers about the real life situation in the rural areas.Center for Advanced Studies in Vaccinology and Biotechnology (CASVAB) University of Balochistan developed a comprehensive training module and gave training to CLEWS of Balochistan Rural Support Program and IUCN. 40% of trained CLEWS have begun earning their livelihood. On average Rs. 2500 to 3000 per month is being earned by each CLEW working in his village.…

Druck auf Anfrage Neuware - Printed after ordering - Research Paper (undergraduate) from the year 2013 in the subject Energy Sciences, grade: Master, , course: Energy Engineering, language: English, abstract: Energy is the important source for the development of the society and it's the basic support of national economy and the base for human living. As the development of economy, abrupt increase of population and continuous improvement of living standards, the demand of energy increases continuously, which caused the impetuous scramble of energy source in the world, and urged the attention of the countries for current status and development trends of energy.…

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Research Paper (postgraduate) from the year 2014 in the subject Energy Sciences, grade: Master, , course: Solar PV, language: English, abstract: In this paper, we examine the solar energy which is the ultimate and free source of energy. Pakistan is situated in the sunny belt that is ideal for the solar energy technologies. This energy is abundantly available in the country as sun shines almost the whole year. The electricity in Pakistan is now facing a serious energy crisis. Despite of strong economic growths during the past decade and consequent rising demand of energy, no valuable steps have been taken to install new capacity for generation of the required energy. In this respect, solar PV is an option for electricity generation. A very large part of the rural population does not have the facility of electricity because they are either too remote or it is found extremely expensive to connect their villages to the national grid station. We can easily utilize the solar PV in some areas of Pakistan; this kind of energy is becoming familiar. Finally, this paper discusses the importance of solar PV technology in rural areas. Geographically, an overview of solar radiation and solar PV option for electricity generation for the country is explored from multiple perspectives comprising technical, economic, social, environmental and political aspects.…

Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Master's Thesis from the year 2014 in the subject Engineering - Power Engineering, , course: Optical Engineering, language: English, abstract: With the increased use of photovoltaic (PV) water pumping system, the photovoltaic (PV) has become one of the most promising technology in solar energy applications. Moreover, PV water pumping system is getting more popular in recent days especially in remote areas to supply water where electricity is economically not available. The present study deals with the simulation of Photovoltaic (PV) based AC motor pumping system and DC motor pumping system equipped with Maximum Power Point Tracker (MPPT) and without MPPT. We performed comparative tests of the two well-known MPPT 'the Perturbation and observation' (P&O) and the 'Incremental Conductance' (IncCond) algorithms using actual irradiance data for different climate conditions, and also explained of various MPPT algorithms and the modeling of PV module is discussed in this thesis.The PV pumping system with DC motor-pump load is simulated and described, whose study is carried out by using SimPowerSystem in MATLAB/SIMULINK and the model is then transfer into MATLAB. The whole system is implemented in MATLAB simulation, and verifies the functionality and benefits of MPPT. Simulations also established comparisons between both systems in terms of performance parameters such as total energy produced and total volume of water pumped a day. The results indicate that the system with MPPT can significantly improve the performance and the efficiency of PV water pumping system as compared to the one without MPPT. The PV pumping system with an inverter fed AC induction motor is studied and simulations are carried out by using MATLAB to verify the functional performance and advantages of MPPT, and the detailed comparison between direct coupled systems and systems with MPPT is also included. The result validates that the pumping system with MPPT has much better performance compared to the system without MPPT.The comparative tests of the two MPPT methods, Perturbation and observation (P&O) and Incremental Conductance (IncCond), are done by MATLAB to the achieve maximum power transfer. The results validate that under cloudy weather conditions, the performance of the IncCond algorithm exhibits slightly higher efficiency than performance of the P&O algorithm. The simulations of the PV system with resistive load with MPPT vs. direct are coupled also carried out. The results show that the system with MPPT can utilize more than (96%) of electric energy produced from PVG (PV generator) and, on the other hand the system wit.…
