Indonesia merupakan negara dengan biodiveristas terbesar kedua di dunia. Berbagai tanaman, hewan dan mikroorganisme dapat tumbuh dan berkembang baik di negara ini. Potensi tersebut sangat mendukung dalam penerapan pola hidup back to nature yang mulai digemari kembali oleh masyarakat. Pemanfaatan bahan alam di segala bidang masih memerlukan kajian yang lebih mendalam. Buku Potensi Senyawa Aktif Bahan Alam ini merupakan salah satu hasil penelitian yang membahas tentang manfaat keanekaragaman hayati yang dimiliki oleh Indonesia. Dari bahasan tentang bagaimana produksi senyawa aktif bahan alam, potensi senyawa bahan alam di bidang kesehatan dan pertanian dan potensi antioksidan dari bahan alam. ...
In our contemporary learning society, expectations about the contribution of education and training continue to rise. Moreover, the potential of information and communication technology (ICT) creates many challenges. These trends affect not only the aims, content and processes of learning, they also have a strong impact on educational design and development approaches in research and professional practices. Prominent researchers from the Netherlands and the USA present their latest findings on these issues in this volume. The major purpose of this book is to discuss current thinking on promising design approaches and to present innovative (computer-based) tools. The book aims to serve as a resource and reference work that will stimulate advancement in the field of education and training. It is intended to be useful in academic settings as well as for professionals in design and development practices.
Reflecting more than a decade's worth of changes, Animal Models in Toxicology, Second Edition is a practical guide to the common statistical problems encountered in toxicology and the methodologies that are available to solve them. The book presents a historical review of the use of animal models and an overview of broad considerations of me
The fungal cell wall is a shield that protects the cells against changes in the extracellular environment, and from the high internal pressure generated during cell growth. These protective attributes are associated with cell wall robustness and strength, but at the same time the wall has to be plastic and dynamic to allow cell growth and communication with the external environment. The main components of the cell wall are sugars, proteins and lipids. Sugars are the most abundant components of the wall, and are mostly present as polysaccharides of glucose (alpha- and beta-glucans), N-acetylglucosamine (chitin), and glucosamine (chitosan). Most of the cell wall proteins are glycoproteins modified by a glycolipid and/or oligosaccharides covalently attached to asparagine (N-linked glycosylation) or serine/threonine residues (O-linked glycosylation). These wall proteins play important roles in cell wall integrity and structure, sensing changes in the extracellular environment, and some of them have adhesive properties and hydrolytic activities.
This accessible and timely book provides a comprehensive overview of how to measure biodiversity. The book highlights new developments, including innovative approaches to measuring taxonomic distinctness and estimating species richness, and evaluates these alongside traditional methods such as species abundance distributions, and diversity and evenness statistics. Helps the reader quantify and interpret patterns of ecological diversity, focusing on the measurement and estimation of species richness and abundance. Explores the concept of ecological diversity, bringing new perspectives to a field beset by contradictory views and advice. Discussion spans issues such as the meaning of community in the context of ecological diversity, scales of diversity and distribution of diversity among taxa Highlights advances in measurement paying particular attention to new techniques such as species richness estimation, application of measures of diversity to conservation and environmental management and addressing sampling issues Includes worked examples of key methods in helping people to understand the techniques and use available computer packages more effectively
This practical text introduces the user to a model process (decide, develop and evaluate) for producing multimedia projects in the classroom.
There is a growing theoretical and practial interest in the topic of metacognition; how we monitor and control our mental processes. Applied Metacognition provides a coherent and up-to-date overview of the relation between theories in metacognition and their application in real-world situations. As well as a theoretical overview, there are substantive chapters covering metacognition in three areas of application: metacognition in education, metacognition in everyday life memory and metacognition in different populations. The book has contributions from many of the leading researchers in metacognition from around the world.
Although diversity is one of the central themes of ecology there is considerable disagreement ab out how it should be measured. I first encountered this problem 10 ycars ago whcn I started my research career and spent a long time pouring ovcr the literature in order to find the most useful techniques. The intervening decade has seen a further increasc in the number ofpapers devoted to the topic of ecological diversity but has led to no consensus on how it should be measured. My aim in writing this book is therefore to provide a practical guide to ecological diversity and its measurement. In a quantitative subject such as the measurement of diversity it is inevitable that some mathematics are...
Metacognition skills have been proven to have a positive relationship with learning. The strength of metacognition relies heavily on self-efficacy where a student understands his/her learning style, and the ability to use information gathered and align it with his/her learning style. In addition, knowing what you know and how you know it as a student plays a huge role in knowing what you do not know and linking it with what is close or relevant to it, that you know. It is about having skills and knowledge that empowers you to be an independent learner. Literature on classroom practices show a number of short-comings in diverse areas such as poor teacher knowledge, overcrowded classrooms, and...
