With the depletion of oil resources as well as the negative environmental impact of fossil fuels, there is much interest in alternative energy sources. Focusing on some of the most important alternate energy sources for the foreseeable future, the Handbook of Plant-Based Biofuels provides state-of-the-art information on the status of the production of biofuels, in particular, bioethanol and biodiesel. After profiling plant-based biofuels, the book gives an overview of the production of biofuels from biomass materials by thermochemical and biochemical methods.

Synthesis has a central role in the development of Science especially in Chemistry. The strategies adopted in synthesis of molecules and materials have undergone considerable changes in recent times and it was felt that it may be necessary to assess and assimilate information on this topic in a single place. Though, no originality is claimed to the contents on this topic, the very fact that the available information on this topic is available in one place itself is considered to be a major step forward.

The third book of four-volume edition of “Solar Cells” is devoted to solar cells based on silicon wafers, i.e., the main material used in today's photovoltaics. Single-crystalline Si (c-Si) modules are among the most efficient but at the same time the most expensive since they require the highest purity silicon and involve a lot of stages of complicated processes in their manufacture. Polycrystalline silicon (mc-Si) cells are less expensive to produce solar cells but are less efficient.

One of the most fundamental question that an Engineer has to ask him/herself is what is how does it deform, and when does it break. Ultimately, it its the answer to those two questions which would provide us with not only a proper safety assesment of a structure, but also how to properly design it. Ironically, botht he ACI and the AISC codes are based on limit state design, yet practically all design analyses are linear and elastic.

The title of this standard should not be taken to imply that all of the materials quoted are necessarily used solely or even principally in building. This schedule was first published in 1935 as an attempt to provide a solution to the problems which had arisen through structural and other calculations being based on different data for the weights of materials concerned. The 1949 revision was undertaken with a view to making the information more complete by the inclusion of certain extra materials, together with such changes in the data as had been found to be necessary....

In order to be suitable for tribological applications, polymeric materials, which can usually exhibit mechanical strength, lightness, ease of processing, versatility and low cost, together with acceptable thermal and environmental resistances, have to show good abrasion and wear resistance. This target is not easy to achieve, since the viscoelasticity of polymeric materials makes the analysis of the tribological features and the processes involved in such phenomena quite complicated.

The new monograph ‘‘Mathematical Modeling in Mechanics of Granular Mate- rials’’ written by Oxana & Vladimir Sadovskii is based on a previous Russian version published in 2008. The Russian version was significantly revised and extended. The References were updated with respect to the readers not being familiar with the Russian language. Instead of eight chapters of the Russian ori- ginal version there are now ten chapters—a new chapter devoted to continua with independent rotational degrees of freedom is added....

Just as human operators must be protected from extreme environments, so must the electronics that operate and control a functional system. When the environment proves too warm, the electronics must be insulated, refrigerated, or simply moved to cooler locations. This last option is sometimes very difficult, or impossible, and the perceived fragility of electronics must then be reconsidered. Vacuum-tube technology provides a historical example of this process.

We live in an era with unparalleled opportunities to practice disease prevention based on knowledge of the earth environment. Although globally distributed early warning systems can monitor physical hazards such as earthquakes and tsunamis, chemical hazards on the other hand—whether actual or potential and natural or anthropogenically induced—remain difficult to accurately identify in time and space. Such hazards often have lengthy asymptomatic latency periods before disability or disease becomes evident....

Similarly, while companies in New York and Ohio filed SARs through multiple entities, a single firm in each state filed the majority of SARs. This was also the case for Wisconsin, ranked fourth among filing locations. For that state, five separate insurance carriers, through one entity, generated 88 percent of filings for the twelve- month period. Unlike in Massachusetts, the Wisconsin-based firm was not affiliated with other companies in and/or from the state during the same time frame.

At present, thickness measurement of materials based on effect of backscattering gamma-ray has been widely used in industry in our country. The report presented research in measuring thickness of some materials such as paper, plastic, aluminum and steel with using the dedicated system of MYO-101, having scintillation detector of YAP(Ce) and gamma-ray of 60 keV of Am-241 source, by Monte-Carlo simulation using the code of MCNP. The simulation was checked by experimental measurements.

This dissertation will outline solution processable materials and fabrication techniques to manufacture flexible electronic devices from them. Conductive ink formulations and inkjet printing of gold and silver on plastic substrates were examined. Line patterning and mask printing methods were also investigated as a means of selective metal deposition on various flexible substrate materials. These solution-based manufacturing methods provided deposition of silver, gold and copper with a controlled spatial resolution and a very high electrical conductivity.
