Crystallization of polymers. Volume 1, Equilibrium concepts - Original PDF
نویسندگان: خلاصه: Polymers of high molecular weight have now been accepted as respectable members of the molecular community. This situation was not always true.(1) It is now recognized, however, that polymer molecules possess the unique structural feature of being composed of a very large number of chain units that are covalently linked together. This property is common to all macromolecules despite their diverse origin, their widely differing chemical and stereochemical structures and uses and function. It is, therefore, possible to study this class of substances from a unified point of view that encompasses the relatively simpler polymers prepared in the laboratory, as well as the more complex ones of nature. The characteristic thermodynamic, hydrodynamic, physical, and mechanical properties possessed by high polymeric substances can be explained, in the main, by their covalent structure and the attendant large size of the individual molecules.
Synthetic Polymers for Biotechnology and Medicine - Original PDF
نویسندگان: خلاصه: One of the most powerful group of chemicals in the body are organic compounds collectively referred to as hormones. The glands responsible for the production and release of hormones comprise the endocrine system. Endocrine activities have been identified in certain organs, such as the heart, kidneys, duodenum, liver and the islets of Langerhans in the pancreas (which contains the insulin gland), which are normally associated with other system functions. There have been numerous attempts to replace organ function using cell transplantation including direct injections of dissociated cells into organs such as the liver, kidney or spleen.1-5 Subcutaneous and intraperitoneal routes have also been evaluated.6-10 More recent investigations have applied extracellular matrix polymers as structural supports for cell transplantation and immunoprotection.11,12 Potential medical applications of such “artificial cells” or “tissue engineered” organoids include an extracorporeal bioartificial liver for detoxification,2 artificial red blood substitutes,13 the extracorporeal artificial kidney for hemodialysis,14 immunosorbents15 and drug delivery systems.16The transplantation of immunoisolated (microencapsulated) cells represents another emerging area in biotechnology research and commercialization. Under such a scenario, the encapsulated cells, which could be a xenograft, would be hidden from the immune system of the body, but would still be able to respond to extracellular stimuli (e.g., blood glucose), with the required hormone, in the case of diabetes therapy insulin, secreted into the systemic circulation. Other applications of the microencapsulation concept include the encapsulation of genetically modified cells, which represents a novel approach to somatic gene therapy.17 This chapter will review recent advances in cell encapsulation from material science, technological and tissue-related perspectives. Cell coating, microencapsulation devices and bioartificial organs will be discussed with the artificial pancreas and treatment of diabetes used as a case study denominator throughout the review.
Adhesives, Sealants, and Coatings for Space and Harsh Environments - Original PDF
نویسندگان: خلاصه: New technologies constantly generate new demands for exotic materials to be used in severe environments. The rapid developments of aerospace industries during the last two decades have required new materials to survive extreme high and low temperatures and various radiations. The exploration of new energy sources, e.g., solar and geothermal, has led us to develop new solar collectors and geothermal devices. Even the search for new oils has demanded that we study the corrosive environment of oil fields. In the telecommunication industries, optical fibers have been adopted broadly to replace metallic conductors. However, none of the optical fibers can survive abrasion or corrosion without the application of a coating material. For microelectronics, protection in terms of coatings and encapsulants is deemed necessary to prevent corrosion. One of the major causes of corrosion has been shown to be water which appears to be abundant in our earthly environments. Water can attack the bulk adhesive (or sealant), the interface, or the adherend. Water can also cause delamination of coating film, and it is definitely the major ingredient in causing cathodic or anodic corrosion. Thus, water becomes the major obstacle in solving durability problems of various materials in harsh environments.
Microbiology Handbook: Dairy Products - Original PDF
نویسندگان: خلاصه: Milk and dairy products form a central part of the human diet, as they are rich in nutrients. On the other hand, because of their high nutrient value, they favour rapid microbial growth. In some cases, this microbial growth is beneficial, while in others it is undesirable. Dairy products may be contaminated with pathogens or microbial toxins; therefore, the microbiology of these products is of key interest to those in the dairy industry. 'Microbiology Handbook - Dairy Products' provides readers with an easy-to-use reference to microorganisms found in milk and dairy products. The handbook covers: initial microflora; sources of contamination; effects of processing on the survival and growth of microorganisms; spoilage; and hazards identified with the consumption of these products.

Successful Stock Signals for Traders and Portfolio Managers: Integrating Technical Analysis with Fundamentals to Improve Performance + Website - Original PDF
نویسندگان: خلاصه: Relative strength performance versus the Standard & Poors (S&P) 500 Index is the key to analyzing any large-cap (capitalization) stock, and is revealing when viewed in Exhibit 1.3. In this chapter, we will exploit the easiest and most powerful examples of technical analysis signals that tracked the demand that took Apple price up so dramatically. Relative strength is simply the comparison of a stock’s price movement to the price movement of the index. This is a simple, straight forward arithmetic ratio. It is then plotted and shown in Exhibit 1.3 as “AAPL: $SPX.” Notice the uptrend in the line created when the stock price is doing better than the index. As long as this line is in an uptrend, it classifies the stock as one that is outperforming the index. The trend line is calculated as a 20-week EMA. If you want to outperform the index this is the signal to watch.
Urban Planning as a Trading Zone - Original PDF
نویسندگان: خلاصه: 'Trading zone' is a concept introduced by Peter Galison in his social scientific research on how scientists representing different sub-cultures and paradigms have been able to coordinate their interaction locally. In this book, Italian and Finnish planning researchers extend the use of the concept to different contexts of urban planning and management, where there is a need for new ideas and tools in managing the interaction of different stakeholders. The trading zone concept is approached as a tool in organizing local platforms and support systems for planning participation, knowledge production, decision making and local conflict management. In relation to the former theses of communicative planning theory that stress the ideals of consensus, mutual understanding and universal reason, the 'trading zone approach', outlined in this book, offers a different perspective. It focuses on the potentiality to coordinate locally the interaction of different stakeholders without requiring the deeper sharing of understandings, values and motives between them. Galison’s commentary comes in the form of the book’s final chapter.
