Dye-Sensitized Solar Cells: Emerging Trends and Advanced Applications is highly focused on addressing all aspects of dye sensitized solar cell technology. In this book, the authors present systematic analysis and working principles and detailed studies of individual components, manufacturing methods, software assisted design surrounding the technology market, commercialization potential, and performance evaluations and detailed fabrication methods and parameters. As there is no specific book which could encircle all the aspects of dye sensitized solar cells from its very basic working principles to advanced approached to improve it efficiency, this book fills that gap. Providing a comprehensive study on dye sensitized solar cells, this reference covers basic working principles to advanced approaches in improving efficiency as well as thermodynamic and kinetic studies. It will be ideal for advanced stage researchers and engineers looking to get a grip on DSSC technology.

I passed my bachelor degree in engineering from MME, CEET, Punjab University, Lahore in 16April 2012. The work presented was my final year bachelor project in which I made a rocket capable of delivering 20 kg package upto 40 km range. The intention behind this work was to develop an easy and systematic approach for rocket design. Material selection methods and approach are also discussed in this book with respect to design stages. Materials play a vital role in rocket performance and light weight high strength material is the key to success. war head function and selection criteria is also discussed but to some extent. one can have online introduction from the link below. http: //www.youtube.com/watch?v=g3sF-Msc8x4

Careless and indiscriminate use of pesticides to control different pests has distressed the natural balance between pests and biological control agents, along with the difficulty of environmental pollution. In the present changing situation of the world, role of the biological control agents cannot be ignored. The potential role of biological control agents in IPM has attracted the concentration of scientists to discover and manipulate the natural enemies instead of conventional control methods, which are mainly dependent on chemical pesticides. Between different biological control agents, mites are well-recognized predators among which the genus Agistemus occupies a significant place.Agistemus mites (Stigmaeidae) are successful predators of destructive mites and other soft-bodied insects.They often establish on plants and can prey on different kinds of harmful mites.Stigmaeidae is a potential significant predatory mite group found throughout the world and among this group, same species might have a very important role in biological control of phytophagous mites and scale insects.

Vegetables are of good nutritional value with significant potential as income-generating crop and as supplements to diet consisting mostly carbohydrates. Despite the importance of vegetables there are different production constraints wherever they are grown in the country. The attack by a variety of insect pests is a major factor restraining increased production of vegetables and is the main cause of low quality and yield. Because of high vulnerability of vegetables to insects, farmers lean to apply chemicals for saving these most perishable agri-products. Farmers adopt different plant protection strategies which mainly focus on over and heavy use of pesticides on these crops. As the pesticide applications are repeated at three days interval therefore there is much chance that the application of pesticides will not only damage the environment but will also incurs severe health concerns on the end consumers.
