Free Download Introduction to key principles of aquaculture by Bruno Augusto Amato Borges
English | January 10, 2024 | ISBN: 177469820X | 251 pages | PDF | 122 Mb
According to FAO's (1989) proposal, aquaculture is the cultivation of aquatic organisms, such as fish, crustaceans, mollusks, and aquatic plants. Traditional stocking, feeding, and safety from predators, among other factors, are all aspects of farming widely used to boost production. Additionally, farming implies individual or corporate tenure of the farmed stock. Aquatic organisms that are exploited by people as a shared property resource with or without proper licensing are the fisheries harvest, whereas aquatic organisms that are reaped by personal or corporate bodies that owned them during their rearing duration contribute to aquaculture for statistical purposes. The utilization of living aquatic resources in a continuous system from capture to culture is what this volume on aquaculture is all about. The relationship between aquaculture, agriculture, and fisheries is examined in light of its fundamentals and potential. Aquaculture has always made use of entrenched ideas, methods, and technologies from the cultivation of terrestrial florae and faunae. Agriculture, aquaculture, and fishing all end up producing final products that compete with one another or complement one another, make use of similar technologies for processing, conservation, or marketing, and call for the same type of research. In specific chapters, the volume provides in-depth descriptions of the general principles and originality of aquaculture art.

Free Download Introduction to Special Relativity (Dover Books on Physics) by James H. Smith
English | March 22nd, 2016 | ISBN: 048668895X | 240 pages | True EPUB (Retail Copy) | 27.02 MB
By the year 1900, most of physics seemed to be encompassed in the two great theories of Newtonian mechanics and Maxwell's theory of electromagnetism. Unfortunately, there were inconsistencies between the two theories that seemed irreconcilable. Although many physicists struggled with the problem, it took the genius of Einstein to see that the inconsistencies were concerned not merely with mechanics and electromagnetism, but with our most elementary ideas of space and time. In the special theory of relativity, Einstein resolved these difficulties and profoundly altered our conception of the physical universe.

Free Download Introduction to Propositional Logic and Set Theory (Understanding Calculus Book 1)
English | August 1, 2025 | ASIN: B0FKVTQ312 | 292 pages | Epub | 42.38 MB
This book is especially useful to students who are about to finish high school and want to properly prepare in mathematics to start college or university. The book is also suitable for those students who have already started higher education. Many of them still face barriers in learning more complex mathematical concepts and their adequate application. A flaw in understanding basic concepts is what makes them reluctant to learn more. Since the objective is to help students achieve an appropriate understanding of basic concepts, this book was written in a plain and simple language in order to make the process of acquiring the mathematical knowledge a friendly, enjoyable and accessible one even for those students who dislike mathematics. However, the simplicity of language does not sacrifice the rigor or depth of the study offered in these pages, which guarantees a satisfactory management of concepts. Students are not required to have math skills; the only requirement is to be interested in learning. In the three chapters that make up this text, we address the building blocks of Calculu s or Mathematical Analysis . We start with Propositional Logic , which provides the language, the logical reasoning, and training on how to properly address mathematical proofs. This chapter is followed by an introduction to Set Theory where we develop a body of concepts that are used in the definition of many fundamental concepts of Calculus such as Function . This book ends with the study of the real number system which is addressed from an axiomatic approach. Throughout the study we offer examples to illustrate all the concepts that we discuss. Furthermore, we propose several sets of exercises to be solved by the students. The answers to those exercises are offered at the end of each chapter. The level of difficulty of such exercises varies from the most elementary level to a moderate level, since the main goal of this book is to help students to properly learn these basic concepts and not to test their mathematical skills. Once the students have completed the study of all the concepts discussed in this book, they will be able to approach with a solid base, and with confidence, the study of the concepts of Calculus such as functions, limits, continuity, derivation, and integration, which will be discussed in upcoming books by this same author.

Free Download Introduction to Neutrosophic Logic By Charles Ashbacher
2002 | 145 Pages | ISBN: 1931233608 | PDF | 1 MB
Neutrosophic Logic was created by Florentin Smarandache (1995) and is an extension / combination of the fuzzy logic, intuitionistic logic, paraconsistent logic, and the three-valued logics that use an indeterminate value.Definition of Neutrosophic Logic:Let T, I, F be standard or non-standard real subsets of the non-standard unit interval ]-0, 1+[,with sup T = t_sup, inf T = t_inf,sup I = i_sup, inf I = i_inf,sup F = f_sup, inf F = f_inf,and n_sup = t_sup+i_sup+f_sup,n_inf = t_inf+i_inf+f_inf.Of course, -0 <= n_inf <= n_sup <= 3+.A logic in which each proposition is estimated to have the percentage of truth in a subset T,the percentage of indeterminacy in a subset I, and the percentage of falsity in a subset F,where T, I, F are defined above, is called Neutrosophic Logic.The sets T, I, F are not necessarily intervals, but may be any real sub-unitary subsets: discrete or continuous; single-element, finite, or (countable or uncountable) infinite; union or intersection of various subsets; etc.They may also overlap. The real subsets could represent the relative errors in determining t, i, f (in the case when the subsets T, I, F are reduced to points).Statically T, I, F are subsets. But dynamically, looking therefore from another perspective, the components T, I, F are at each instance dependant on many parameters, and therefore they can be considered set-valued vector functions or even operators.T, I, and F are called neutrosophic components, representing the truth, indeterminacy, and falsehood values respectively referring to neutrosophy, neutrosophic logic, neutrosophic set, neutrosophic probability, neutrosophic statistics.This representation is closer to the reasoning of the human mind. It characterizes / catches the imprecision of knowledge or linguistic inexactitude perceived by various observers (that's why T, I, F are subsets - not necessarily single-elements), uncertainty due to incomplete knowledge or acquisition errors or stochasticity (that's why the subset I exists),and vagueness due to lack of clear contours or limits (that's why T, I, F are subsets and I exists; in particular for the appurtenance to the neutrosophic sets).The advantage of using neutrosophic logic is that this logic distinguishes between relative truth, that is a truth in one or a few worlds only, noted by NL(relative truth)=1, and absolute truth, that is a truth in all possible worlds, noted by NL(absolute truth)=1+. And similarly, neutrosophic logic distinguishes between relative falsehood, noted by 0, and absolute falsehood, noted by -0.In neutrosophic logic the sum of components is not necessarily 1 as in classical and fuzzy logic, but any number between -0 and 3+, and this allows the neutrosophic logic to be able to deal with paradoxes, propositions which are true and false in the same time: thus NL(paradox)=(1, I, 1); fuzzy logic can not do this because in fuzzy logic the sum of components has to be 1.[/center]

Free Download Introduction to N-Adaptive Fuzzy Models to Analyze Public Opinion on Aids By W. B. Vasantha Kandasamy, Florentin Smarandache
2006 | 236 Pages | ISBN: 1931233128 | PDF | 1 MB
People living with HIV/AIDS have always been victims of the most extreme forms of social discrimination. They are stereotyped and stigmatized, and are seen as people outside the 'general population'.In this book The authors use mathematical tools to attempt an understanding of public awareness and attitude towards people living with HIV/AIDS.Here, for the first time, a new model, called n-adaptive fuzzy model, has been introduced. This model has the capacity to analyze the same problem in different ways thereby arriving at various solutions that mirror multiple perspectives.

Free Download Introduction to Indoor fish farming by Dhanaji Patil
English | January 10, 2024 | ISBN: 1774698382 | 255 pages | PDF | 28 Mb
World population is growing exponentially with increasing demand in food security. Aquaculture is one of the fastest-growing, food-producing sectors accounting for nearly 50% of the world's fish production. Aquaculture is culture of aquatic plants and animals in aquatic environment. Last few decades, aquaculture is becoming more reliable, efficient and sustainable source of high quality food production. Though, its major goal is to produce aquatic food for human consumption, but also has other goals, such as ornamental and sport fish cultivation. It also reduces stress on capture fishery which under threat due to over-fishing, habitat loss or other changes due to possible pollutants they have consumed or been exposed. However, aquaculture technology is continuously advancing through technological innovation to maximise yield/ha with less inputs and impact on environment. The farming of aquatic animals in controlled environment such as tanks, ponds or RAS in indoor premises is known as indoor fish farming. Indoor fish farming is one of the source of animal protein production to this day, especially in locations far from the sea. It allows fish to be raised in a controlled and optimised environment with increased control on water quality, feeding and diseases monitoring. Though, it requires significant initial investment, planning and expertise to establish, but has more advantages over open culture. Moreover, it is possible in urban area or area where land and water scarcity. Optimal water quality for the good health and growth of cultured fish species is achieved through proper oxygenation, feeding, filtration and removal of waste products to get control on ammonia, nitrate and nitrite. It too offers potential benefits in terms of water conservation, reduced environmental impact, efficient resource utilization, optimal FCR and risk of fish escapement. This book scientifically focuses on advances, operation, economics, management as well as challenges and safety in indoor aquaculture along with its impact on human beings. This book also touches SSFs, capture fisheries and its subsequent management. This book potentially serves as a manual for interested aquaculturist, policy makers as well as students pursuing graduation, post-graduation and research studies.
