In this book, PLA Nanocomposite is discussed from its origin. What is nanocomposite and what is currently being discovered in this field? PLA nanocomposite with varies synthetic methods were also described. Common characterization methods were discussed with few examples. While in last section all the enhancement & applications based various examples of PLA Nanocomposites were discussed with the situation of logical core. This book is upright for the beginners and learners.
Polymer Core-Shell particles, consisting two different polymers each having different property, are widely used as compatibilizer for incompatible blend and impact modifier of plastics. We have shown an environment friendly approach to obtain thermally stable Polystyrene-Poly(methyl methacrylate)/Clay Core-Shell, micron sized nanocomposite particles using exfoliated sodium montmorillonite clay platelets by in-situ seeded suspension polymerization technique. After thorough characterization, it has been found that thermal stability strongly depends on location and loading of clay either in the core/shell phase or both phases of the particles.
Alternative Arrangements for Marine Fisheries; An Overview by Francis T. Christy, Jr.
In search for newer analytical techniques that can meet the growing trend in the world of elemental analysis, the Inductively Coupled Plasma (ICP) system is exploited. A cursory look at the driving forces behind this analytical tool and its use in series with other analytical tools with reference to some literature reports has been critically reviewed. Aspects of maintenance of the ICP system and metal speciation were also highlighted.
Breast cancer is the most common cancer(22% of all new cases) as well as the leading cause of cancer deaths(14% of all cancer deaths)in women worldwide.The incidence of breast cancer is increasing at an alarming rate in India cuttting across urban and rural divide.Country as vast as India poses its own share of peculiar problems with lack of awareness about the disease,advanced stage of disease presentation and lack of proper screening and treatment facilities.We present an Indian prespective of the demographics and problems encountered in treatment of breast cancer.
Biosimilars have been a buzz word in pharmaceutical industry now-a-days due to melting of generic products and growth of biological in terms of market capture and efficiency. Also the biological products are more technology driven than the chemical products. Due to more novelty and technology there is a strong need of biosimilar regulations. Keeping in view to this, most of all the regulatory authorities have formed the biosimilar regulations leaded by US FDA and followed by INDIAN, Canadian, Japanese, Chinese, Korean and Singapore regulatory authorities. The stringent of all are USFDA regulations followed by Health Canada.
Regulations concerning automotive emissions are becoming more stringent in recent times and consequently more research efforts have directed toward lowering the environmental impact of pollutants emitted by vehicles and industries. In this context, the research focus has been aimed at the development of more efficient and highly resistant catalytic materials which could be able to maintain maximum durability while decreasing pollutant emissions to minimum levels. Three-way catalysts (TWCs) constitute the most satisfactory and efficient solution to reduce pollutant emissions from gasoline-engine-powered vehicles. This book which is based on a comprehensive research study gives an insight on the development of novel nanosized cerium oxide based catalysts for TWC and other catalytic applications. It contributes invaluable information on how catalysts composition can be manipulated for better performance. This book will be especially useful to researchers working in the field of catalysts development, catalyst''s structural analysis, environmental catalysis, and more specifically in the area nanocatalysis.
Plants produce chemicals called hormones which are produced in one part of the plant to signal cells in another part of the plant to respond. Many flowering plants bloom at the appropriate time because of light-sensitive compounds that respond to the length of the night, a phenomenon known as photoperiodism. The ripening of fruit and loss of leaves in the winter are controlled in part by the production of the gas ethylene by the plant.
Heterosis is a widely occuring biological phenomenon in both the plants and animal species. The exploitation of heterosis is a common objective in plant breeding. In forest tree breeding this usually takes the form of strategies to avoid inbreeding depression or the exploitation of positive heterosis through deployment of high performing full sibs in either family or clonal forestry. The tailoring of tree in future biomass production by genetic manoeuvring holds a great promise. Depending upon breeding objectives, both positive and negative heterosis is useful for crop improvement. In general, positive heterosis is desired for yield and negative heterosis for early maturity. The manifestation of heterosis has enabled plant and tree breeders to significantly improve the tree performance by exploiting hybrid vigour. The many studies on quantitative genetics in forestry over the past 20 years have helped to advance breeding populations. With the availability of modern molecular tools, scientists can begin to explore the phenomenon of heterosis into its individual genetic components should provide new help to guarantor a plentiful supply of quality products for the future generations.
The notion that fatty acid intake may influence the incidence of tumorigeneis and cancer has been studied intensively in vivo and in vitro for more than thirty years and seems to be widely accepted. Ranging form epidemiological studies to those conducted using cell cuture models, most studies provide evidence that certain long chain polyunsaturated fatty acids are able to inhibit the development of cancer or slow down tumor growth. However, the cellular and molecular mechanisms responsible for these effects have not yet been clarified, although various hypotheses exist. Therefore the aim of this chapter is to discuss: PART I: The epidemiological evidence; PART II: The modulation of signaling pathways and the regulation of cell death by fatty acids; and PART III: To give an overview on clinically relevant fatty acids and rationale for adjuvant fatty acid therapy.
GARP's Fundamentals of Energy Risk Management introduces investors to the basic components and some of the basic terminology used in the energy industry. It covers the commodity cycle, energy use and sources, and various risk types, various energy products and the markets where energy is traded. It also introduces certain risk management fundamentals and real option thinking. The book is GARP's required text used by risk professionals looking to obtain their Certificate in Energy Risk Management.
Over the past few decades there has been great interest in exploring alternatives to conventional separation methods due to their high cost and energy requirements. Membranes offer a potentially attractive alternative as they potentially address both of these points. The overarching theme of this work is to design nanocomposite membranes for processes where existing separation schemes are inadequate. This book focuses on three challenges: 1) designing organic-inorganic hybrid membranes for reverse-selective removal of alkanes from light gases, 2) defect-free inorganic nanocomposite membranes that have uniform pores, and 3) organic-inorganic hybrid membranes and photocatalytic membranes for minimizing protein fouling in microfiltration applications. Also, the author presents the basic membrane theories for the readers who are not familiar with membrane.
In the large field of nanotechnology, polymer matrix based nanocomposites have become a prominent area of current research and development. This book deal with the fabrication of nanocomposite (PANI_CNTs nanofiber) by electrochemical method for NH3, HCl, and H2 sensors with described the mechanism of its interactions. The effect of weight proportion of CNTs to polyaniline to making nanofiber composite on sensitivity and response time and recovery time are described.
