Principles of Tissue Engineering Fifth Edition - Original PDF
نویسندگان: خلاصه: Now in its fifth edition, Principles of Tissue Engineering has been the definite resource in the field of tissue engineering for more than a decade. The fifth edition provides an update on this rapidly progressing field, combining the prerequisites for a general understanding of tissue growth and development, the tools and theoretical information needed to design tissues and organs, as well as a presentation by the world’s experts of what is currently known about each specific organ system. As in previous editions, this book creates a comprehensive work that strikes a balance among the diversity of subjects that are related to tissue engineering, including biology, chemistry, material science, and engineering, among others, while also emphasizing those research areas that are likely to be of clinical value in the future. This edition includes greatly expanded focus on stem cells, including induced pluripotent stem (iPS) cells, stem cell niches, and blood components from stem cells. This research has already produced applications in disease modeling, toxicity testing, drug development, and clinical therapies. This up-to-date coverage of stem cell biology and the application of tissue-engineering techniques for food production – is complemented by a series of new and updated chapters on recent clinical experience in applying tissue engineering, as well as a new section on the emerging technologies in the field.
Direct Microscopic Somatic Cell Count - Original PDF
نویسندگان: خلاصه: The direct microscopic somatic cell count (DMSCC) is microscopic count of the actual number of somatic cells in milk. A somatic cell is any biological cell forming the body of an organism. In dairy industry, the somatic cell count (SCC) is an indicator of the safety and quality of milk. Mastitis is an inflammation of the udder typically associated with microbial infection. The number of somatic cells increases in response to presence of pathogenic bacteria like Staphylococcus aureus, a cause of mastitis. Somatic cells (SC) are cells from the cow (predominantly white blood cells, otherwise known as leukocytes) that are normally present in milk. During most mastitis infections, the number of leukocytes present in the udder increases to help the cow, goat, ewe, camel, buffalo etc. to fight the infection. The SCC is quantified as cells per milliliter. General agreement rests on a reference range of less than 100,000 SC in ml for uninfected cows and greater than 250,000 SC in ml for cows infected with significant pathogen levels. There are several indirect and direct laboratory methods used for determination of somatic cells count in milk. Routine instrumental laboratory methods like flow cytometry have to be regularly calibrated using reference materials with a known concentration of somatic cells. The concentration of somatic cell count can be determined by reference microscopic method. The first microscopic procedure for examination of milk films was described in 1910 by Prescott and Breed. Staining of somatic cells was later modified by Newman, Lampert, Levowitz, Weber and other researchers. This microscopic method was processed into a normative form by the International Dairy Federation and later by International Standard Organisation. There are several possibilities to stain somatic cells. Somatic cells can be stained by dipping the dried smear on the slide in the modified Newman-Lampert methylene blue stain solution (cow’s milk and ewe’s milk) or methyl green-pyronin Y stain solution (goat’s milk) or by mixing the milk in reagent tube with ethidium bromide stain solution (milk from all species). Subsequently, the microscopic slide with fixed smear and stained cells is examined using a microscope or epifluorescence microscope with immersion oil objective at magnification 500× to 1000×. Somatic cells are counted in several microscopic fields. Consequently, the somatic cells count is calculated using one of several mathematical formulas listed in international standard. The direct microscopic somatic cell count method is suitable for precise laboratory analysis of somatic cell in raw milk. However, this microscopic method has some limitations that may influence the results of analysis. This book contains the theoretical and practical information about this laboratory method.
Quantum thermodynamics: emergence of thermodynamic behavior within composite quantum systems - Original PDF
نویسندگان: خلاصه: This extended tutorial essay views thermodynamics as an incomplete description of quantum systems with many degrees of freedom. The main goal is to show that the approach to equilibrium - with equilibrium characterized by maximum ignorance about the open system of interest - neither requires that many particles nor is it a precise way of partitioning relevant for the salient features of equilibrium and equilibration. Moreover it is indeed quantum effects that are at work in bringing about universal thermodynamic behaviour of modestly sized open systems. Von Neumann`s concept of entropy thus proves to be much more widely useful than something to be feared, and far beyond truly macroscopic systems in equilibrium.
A Commissioner’s Primer to Economics of Competition Law in India - Original PDF
نویسندگان: خلاصه: Open market functioning has many supporters as detractors biased in favor of regulation and competition rather than regulation and control. These divergent pulls frame the political economy of regulation and competition. Paradigm shifts in economic policies from regulation to competition is a layered process beset with distinguishing the process from regulating a sector to regulating markets for competitiveness. In India at least the processes are not sharply defined. Regulation has always been central to the industrial strategies adopted by the Government of India. Discussions on regulation per se contend with differing perspec- tives of welfare maximization of economic welfare and consumer harm. The underlying debates on industrial strategies preceding the shift to economic liberalization was on the opening of sectors to private invest- ments and the sequencing of reforms at the macro-level of current account versus capital account liberalization and at the micro-level of the sectors that need regulation on account of their economic charac- teristics of natural monopoly such as power sector and telecom (Geeta, 2020, 2017). The debate in these sectors was on the balance of power in the structure of designated regulatory body or sector commissions.1 The paradigm shift to an open economy and a market facilitator was much slower with the Competition Commission established a decade later. The debates were on agreements that result inappreciable effect on competi- tion to entry barriers legally created or market created to abuse of marke
Education, Human Capital Investment, and Innovation in the Contemporary Japanese Economy - Original PDF
نویسندگان: خلاصه: Analyzing the determinants of educational attainment, with class size being one of the most important among them, is crucial in investigating the accu- mulation of human capital and economic growth. However, we have not yet reached a clear conclusion regarding the relationship between class size and educational attainment. Some empirical studies show a positive correlation, while others find the correlation negative. In this chapter, we analyze the direct and indirect impacts of class size on educational attainment through the allocation of teachers’ efforts. We focus on the relationship between class size and teachers’ working hours to construct a formal model that endogenizes the time spent outside of class to prepare teaching materials and the time spent preparing for classes. The empirical results reveal that the relationship between class size and educational attainment can be U-shaped, inverted U-shaped, upward sloping, or downward sloping. This suggests the exis- tence of the optimal class size as well as the most inappropriate class size. In addition, the analysis points out that grade levels and the characteristics of each subject are as important as class size in achieving the maximum educational attainment, given limited educational resources
Product Design A Product-Led perspective about digital product design - Epub + Converted PDF
نویسندگان: خلاصه: The question is quite pertinent. Especially when we are starting a new project or we are faced with a situation that needs further study on a certain topic. Perhaps this discussion is more related to a natural tendency that every human being has. When we are faced with a problem, the brain's immediate reaction is to find a solution that is faster and requires the least amount of energy to solve. Nature works this way. As a professional, it is extremely important to solve any UX problem as comprehensively as possible, without trying to find the easiest solution or putting yourself in the user's shoes in a superficial way. What I have learned from nearly 20 years of professional career is that the greater the knowledge on a given topic, the less research I need. And that's not bad, on the contrary. The greater my knowledge of a task, the greater my empathic ability to provide solutions that are appropriate and that make sense to most users. The greater my knowledge of a subject, the greater my ability to sell that product or sell my idea.آیا کتاب مورد نظر هنوز بر روی سایت قرار نگرفته است؟ جای نگرانی نیست! کافی است بر روی گزینه سفارش کتاب کلیک کرده و درخواست خود را ثبت کنید. در کمتر از چند ساعت کتاب شما را آماده خواهیم کرد.
