This chapter describe how proton pumps function in transport of materials across membranes; define the following terms: osmosis, water potential, flaccid, turgor pressure, turgid; explain how aquaporins affect the rate of water transport across membranes; describe three routes available for short-distance transport in plants;...
As a wetland of international importance located in China, the Poyang Lake Basin's incredible topographical and biological diversity has provided a congregating point for scientists from around the world to engage in cross-disciplinary research. In particular, the International Conference on Poyang Lake Complex Environment System was instrumental in bringing together scholars from China, North America, and Europe to explore the latest innovations in water resource science and watershed management.
The state of aquatic ecosystems reflects the general state of the biosphere. The situation
in the biosphere affected by anthropogenic factors was characterized as “a slow
explosion” (Fedorov 1987). The global change in the biosphere and climatic system
of the Earth is a manifestation of this “slow explosion” (World Resources
1990–1991, Izrael et al. 1992).
The science of vascular biology has emerged and expanded rapidly over the past 25
years. Research in this area has increased understanding of a wide range of clinical
conditions. This book provides a broad overview of the Weld for both specialist
and newcomer to the Weld, and concise resource for the non-specialist. The
multidisciplinary team of contributors covers topics ranging from normal and
pathological aspects of endothelial cell function to the role of the vasculature in
pregnancy, hypertension and atherosclerosis....
Conserving Living Natural Resources provides students, managers, and general readers with an
introduction to the principles of managing biological resources. It presents the historical and
conceptual contexts of three seminal approaches to the management of living natural
resources: utilitarian management for harvest of featured species and control of unwanted
species, protection and restoration of populations and habitats to maintain biodiversity, and
management of complex ecosystems to sustain both productivity and biodiversity.
From microorganisms to whales, from single cells to complex organisms,
from plants to animals to fungi, from body plans to behavior, the diversity
of life is amazing. Living organisms have a profound impact on our
physical world of ocean, landscape, and climate; around us is a multitude
of diverse ecosystems that provide a livable environment and many valuable
resources. The study of life—biology—is a multifaceted endeavor that uses
observation, exploration, and experiments to gather information and test
hypotheses about topics ranging from climate change to stem cells.
Over the years, I have not lost my enthusiasm for ecological economics and
the conservation of nature. Therefore, I was delighted when Edward Elgar
told me that he would be interested in publishing a second edition of
Economics of Environmental Conservation and suggested a practical method
for producing the new manuscript. The first edition of the Economics of
Environmental Conservation was published in 1991 by Elsevier Science
In this paper, we demonstrate three NLP applications of the BioLexicon, which is a lexical resource tailored to the biology domain. The applications consist of a dictionary-based POS tagger, a syntactic parser, and query processing for biomedical information retrieval. Biological terminology is a major barrier to the accurate processing of literature within biology domain. In order to address this problem, we have constructed the BioLexicon using both manual and semiautomatic methods. We demonstrate the utility of the biology-oriented lexicon within three separate NLP applications. ...
Goal It is to provide scientific arguments about the biological characteristics, and reproductive and rearing techniques of Channa lucius. The success of the project will contribute greatly to the development process of Channa lucius hatchery to supply artificial fish for aquaculture systems and renewable fish resources in the wild in the Mekong Delta as well as in the whole country.
Optimal use of genome sequences and gene-expression resources requires powerful phenotyping platforms, including those for systematic analysis of metabolite composition. The most used technologies for metabolite profiling, including mass spectral, nuclear magnetic resonance and enzyme-based approaches, have various advantages and disadvantages, and problems can arise with reliability and the interpretation of the huge datasets produced. These
This strategy provides a tool to support co-ordinated action to improve and expand quality nutrition
programming in Somalia in a phased approach over the next three years. It is based on a logical
framework and is therefore rooted in actions that if conducted produce results that ultimately mean
outcomes are accomplished and the overall development goal is achieved. It is intended as an
advocacy document for UN agencies and partners to donors.
With the overwhelming amount of biological knowledge stored in free text, natural language processing (NLP) has received much attention recently to make the task of managing information recorded in free text more feasible. One requirement for most NLP systems is the ability to accurately recognize biological entity terms in free text and the ability to map these terms to corresponding records in databases.
In this paper, we propose an approach for identifying curatable articles from a large document set. This system considers three parts of an article (title and abstract, MeSH terms, and captions) as its three individual representations and utilizes two domain-specific resources (UMLS and a tumor name list) to reveal the deep knowledge contained in the article. An SVM classifier is trained and cross-validation is employed to find the best combination of representations. The experimental results show overall high performance. ...
Plant cell walls represent the most abundant renewable resource on this planet. They are
rich in mixed complex and simple biopolymers, which has opened the door to the
development of wide applications in different technologic fields.
Chapter 53 - Population ecology. In this chapter, you should now be able to: Define and distinguish between the following sets of terms: density and dispersion; clumped dispersion, uniform dispersion, and random dispersion; life table and reproductive table; Type I, Type II, and Type III survivorship curves; semelparity and iteroparity; r-selected populations and K-selected populations. This chapter also explain how ecologists may estimate the density of a species, explain how limited resources and trade-offs may affect life histories,...

What is Economics? Economics is not a natural science, i.e. it is not concerned with studying the physical world like chemistry, biology. Social sciences are connected with the study of people in society. It is not possible to conduct laboratory experiments, nor is it possible to fully unravel the process of human decisionmaking. “Economics is the study of how we the people engage ourselves in production, distribution and consumption of goods and services in a society.” Normative economics and Positive Economics: Normative economics refers to value judgments, e.g.
