ELECTRONIC RESOURCES FOR THE HUMANITIES  

Directory of Open Access Journals (Sweden)

Full Text Available Electronic information resources (EIR) including electronic journals, books, and databases, as well as other different collections of information on the internet either paid or accessed for free withoutany doubt became one of the most important information resources in contemporary research and studies. The point is whether representatives of all fields of sciences use them with equal intensity and effectiveness. There is an opinion, that EIR are more applicable for physical, biomedical and technological sciences and representatives of these sciences are better prepared and use them much more extensively. It is thought that those, who study liberal arts, are technophobial, moreover, representatives of liberal arts themselves maintain that manuscript material is frequently moreimportant than electronic information, that books are primary and not articles.The aim of the article is to overview the peculiarity of representatives of liberal arts and to present an evaluated qualitative and acknowledged register of electronic information resources, which could be useful for representatives of liberal arts, ensure supplying of specific information needs and disseminate information about electronic information resources.To implement this goal the following tasks are solved in the article: problems of typology of electronic information resources are discussed and their original classification scheme presented based on theoretical and practical material; assessment criteria of electronic information resources are analyzed; an annotated list of electronic information resources for representatives of liberal arts is presented.The article may be relevant to the whole community of representatives of liberal arts: researchers, lecturers, students, as well as library specialists and others, interested in electronic information.

Student attitudes towards electronic information resources  

Directory of Open Access Journals (Sweden)

Full Text Available Students are increasingly expected to use electronic resources while at university. Studies were undertaken to determine the level of use of this type of resource, how students feel about various issues surrounding electronic resources and whether attitudes change dependent upon subject studied. 317 students across three universities completed questionnaires to determine level of use of various electronic information resources; ways in which they felt electronic resources had hindered or improved their academic career; if they perceived themselves capable of using the resources; would the standard of their work suffer without the use of these resources; and the various methods employed to acquire the skills necessary to use the sources. 155 students were questioned as part of a larger study IMPEL2, investigating the Impact on People of Electronic Libraries, supplemented by 162 students, questioned as part of an MA Dissertation, using the same methodology.

Use of electronic information resources in goverment libraries  

Directory of Open Access Journals (Sweden)

Full Text Available The article presents the use of electronic information resources in government libraries in Slovenia. It starts with the definition of government libraries and electronic publications. On a selected sample of government libraries, the state of the usage of electronic information resources in government libraries was studied. On the basis of interviews, carried out in five government libraries, it was established that government libraries mostly do not focus on, or even think about, the use of electronic information resources. What they have and use seems self-evident to them.

User Perception of Electronic Resources in the University of Ilorin  

Directory of Open Access Journals (Sweden)

Full Text Available This study examined the user perception of the electronic resources by the academic staff of the University of Ilorin. The sample consists of 250 academic staff selected from eight (8) out of the twelve (12) faculties that made up of the university. Data were collected through an electronic resources user perceptional survey (ERUPS). Responses were received from 225 (90%) academic staff of the eight faculties. Analysis revealed frequency of use of electronic resources was low. Reasons alluded to were lack of time because of the time required to focus on teaching; lack of awareness to electronic resources provided by the library; power outage, ineffective communication channels, slow network and inadequate searching skills. The study recommended adequate Information and Communication Technologies (ICT) training for all categories of academic staff and provision of adequate power supply.

Freshmen's use of library electronic resources and self-efficacy  

Directory of Open Access Journals (Sweden)

Full Text Available To encourage students use of the library, and in particular of its electronic resources, we need to understand what factors encourage students to seek out information in the library setting. Research has shown that self-efficacy influences academic achievement. This paper looks at the role self-efficacy plays in their search for information and use of the library's electronic resources, by surveying a class of freshmen at Baruch College. Their library and computer use were analyzed and correlated with their self-efficacy scores. Through statistical analysis, we found that use of the library correlated to the students' use of the library's electronic resources. We also found out that students who express an interest in learning about the library's electronic resources will be more likely to have higher self-efficacy.

Snow ball earth and the split of Streptophyta and Chlorophyta.  

UK PubMed Central (United Kingdom)

About 700 million years ago (Mya), the ancestor of all green plants evolved into two major groups: the Chlorophyta (many green algae) and the Streptophyta (some green algae and land plants = embryophytes). Both groups are separated by several morphological, physiological, and molecular characteristics, including different photorespiration pathways. The Chloropyhta/Streptophyta split was probably very important for the colonization of the terrestrial habitat because embryophytes, the descendants of streptophyte algae, today completely dominate the macrophyte flora of the terrestrial habitats. By contrast, in aquatic ecosystems macrophytes from brown, red, and green algae compete with embryophytes. In this opinion article, I argue that the Chlorophyta/Streptophyta split is related to glaciation events (snow ball earth states) in the Neoproterozoic and provide an explanation for the different photorespiration pathways.

Why and How to Measure the Use of Electronic Resources  

Directory of Open Access Journals (Sweden)

Full Text Available A complete overview of library activity implies a complete and reliable measurement of the use of both electronic resources and printed materials. This measurement is based on three sets of definitions: document types, use types and user types. There is a common model of definitions for printed materials, but a lot of questions and technical issues remain for electronic resources. In 2006 a French national working group studied these questions. It relied on the COUNTER standard, but found it insufficient and pointed out the need for local tools such as web markers and deep analysis of proxy logs. Within the French national consortium COUPERIN, a new working group is testing ERMS, SUSHI standards, Shibboleth authentication, along with COUNTER standards, to improve the counting of the electronic resources use. At this stage this counting is insufficient and its improvement will be a European challenge for the future.

Discipline, availability of electronic resources and the use of Finnish National Electronic Library - FinELib  

Directory of Open Access Journals (Sweden)

Full Text Available This study elaborated relations between digital library use by university faculty, users' discipline and the availability of key resources in the Finnish National Electronic Library (FinELib), Finnish national digital library, by using nationwide representative survey data. The results show that the perceived availability of key electronic resources by researchers in FinELib was a stronger predictor of the frequency and purpose of use of its services than users' discipline. Regardless of discipline a good perceived provision of central resources led to a more frequent use of FinELib. The satisfaction with the services did not vary with the discipline, but with the perceived availability of resources.

Biocompatible Hydrogel from a Green Tide-Forming Chlorophyta  

Directory of Open Access Journals (Sweden)

Full Text Available The green-tide chlorophyta Ulva contains the functional acidic polysaccharide ulvan in its cell wall. Here, we focused on the development of a novel soft material that can be used as a biocompatible ion exchanger. Combining chitosan and ulvan solutions was found to yield a hydrogel with various functions. This ulvan-chitosan polyion complex gel was more stable than an alginic acid-chitosan gel under both acidic and basic conditions. However, an ulvan-chitosan gel-coated vessel showed only a mild effect of preventing blood clotting, whereas a heparin-chitosan gel-coated vessel prolonged clotting time. In terms of the ion-exchange behavior, the ratio of the CuSO4-concentration in a CuSO4 solution treated with the gel to that in a solution without the gel showed that increasing the initial CuSO4 concentration increased CuSO4 adsorption in the gel. These studies show that this novel hydrogel can be used as an ion exchanger as well as in other applications.

eFG: an electronic resource for Fusarium graminearum.  

Science.gov (United States)

Fusarium graminearum is a plant pathogen, which causes crop diseases and further leads to huge economic damage worldwide in past decades. Recently, the accumulation of different types of molecular data provides insights into the pathogenic mechanism of F. graminearum, and might help develop efficient strategies to combat this destructive fungus. Unfortunately, most available molecular data related to F. graminearum are distributed in various media, where each single source only provides limited information on the complex biological systems of the fungus. In this work, we present a comprehensive database, namely eFG (Electronic resource for Fusarium graminearum), to the community for further understanding this destructive pathogen. In particular, a large amount of functional genomics data generated by our group is deposited in eFG, including protein subcellular localizations, protein-protein interactions and orthologous genes in other model organisms. This valuable knowledge can not only help to disclose the molecular underpinnings of pathogenesis of the destructive fungus F. graminearum but also help the community to develop efficient strategies to combat this pathogen. To our best knowledge, eFG is the most comprehensive functional genomics database for F. graminearum until now. The eFG database is freely accessible at http://csb.shu.edu.cn/efg/ with a user-friendly and interactive interface, and all data can be downloaded freely.

Directory of Open Access Journals (Sweden)

Full Text Available ?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????/??????????????????????????????????????????????????The emergence of electronic resources has made new breakthrough in knowledge carriers because of their ease of use, instant availability, and the characteristic of no time and space constraints. For public libraries to achieve maximum efficiency in its electronic resources, it is necessary to seek the most effective marketing strategies. Therefore, the marketing concept of the electronic resources should be reader oriented, such as respecting and understanding library user’s information needs. Libraries also need to utilize various media and techniques to market the electronic resources, so that more comprehensive services and experiences can be provided to readers. The purpose of this study is to investigate library user’s needs and promotion strategies of electronic resources in order to identify the most effective ways of marketing. This study focuses on the students of the four colleges (College of Business, College of Tourism, College of Information, and College of Humanities and Social Science) in Kainan University as subjects in the survey questionnaire. It uses the Gap Analysis Model as the main analytical tool to examine cases in which readers/ students show real demands to electronic resources. The study concludes with promotion and marketing strategies with regards to service offerings for the university libraries.

Using Electronic Repositories as a Student Resource for MSE Applications  

Science.gov (United States)

In the majority of engineering disciplines, MSE provides resources and applications with many other areas of engineering, e.g., design, structures, mechanics, and manufacturing. For the students to transfer and implement their MSE knowledge, they must have easy access to all their information. The eportfolio is a repository of the students entire academic MSE content and provides a wealth of knowledge applicable to all engineering disciplines. This repository combines not only lecture and textbook material, but also every assignment (in assessed format), all quizzes (with answers) laboratory activities (in audiovisual format), student oral presentations (podcast), and lectures in asynchronous format. This allows all of the data and information accumulated by students throughout their varying MSE course collected in one place, and is able to act as a quick resource and information kit for future use as the eportfolio is quickly accessed. Student and graduate responses have been positive especially for those in the workforce who require immediate and correct information.

Disseminating Context-Specific Access to Online Knowledge Resources within Electronic Health Record Systems.  

UK PubMed Central (United Kingdom)

Clinicians' patient care information needs are frequent and largely unmet. Online knowledge resources are available that can help clinicians meet these information needs. Yet, significant barriers limit the use of these resources within the clinical workflow. Infobuttons are clinical decision support tools that use the clinical context (e.g., institution, user, patient) within electronic health record (EHR) systems to anticipate clinicians' questions and provide automated links to relevant information in knowledge resources. This paper describes OpenInfobutton (www.openinfobutton.org): a standards-based, open source Web service that was designed to disseminate infobutton capabilities in multiple EHR systems and healthcare organizations. OpenInfobutton has been successfully integrated with 38 knowledge resources at 5 large healthcare organizations in the United States. We describe the OpenInfobutton architecture, knowledge resource integration, and experiences at five large healthcare organizations.

Eavesdropping on Electronic Guidebooks Observing Learning Resources in Shared Listening Environments  

CERN Document Server

We describe an electronic guidebook, Sotto Voce, that enables visitors to share audio information by eavesdropping on each other's guidebook activity. We have conducted three studies of visitors using electronic guidebooks in a historic house: one study with open air audio played through speakers and two studies with eavesdropped audio. An analysis of visitor interaction in these studies suggests that eavesdropped audio provides more social and interactive learning resources than open air audio played through speakers.

Se presenta el aislamiento de 11 cepas de microalgas de la división Chlorophyta de dos ambientes distintos caracterizados por ser efluentes de aguas residuales. Se sembraron en me (more) dio selectivos y se purificaron a través de diluciones seriadas, siembras por agotamiento y aplicación de penicilina y gentamicina. Se evaluaron la producción de biomasa y se escogieron dos cepas la CHL1 (Chlorella sp.) y DES1 (Desmodesmus sp.) y se sembraron en aguas residuales y medio PCG (control), midiendo la concentración de biomasa y el contenido lipídico de las mismas. Ambas cepas alcanzaron concentraciones de biomasa similares a sus respectivos controles (CHL1 PCG 1.5 mg/L ± 0.035 mg/L, CHL1 AR 1.68 mg/L ± 0.036, DES1 PCG 1.66 mg/L ± 0.007, DES1 AR 2 mg/L ± 0.03) y en cuanto al contenido de lípidos, este fue ligeramente mayor a los obtenidos en los controles. Los resultados obtenidos mostraron que las cepas aisladas y evaluadas prometen ser promisorias para la producción de lípidos, ya que aún no se han modificado condiciones ambientales y nutricionales que pueden aumentar el contenido de los mismos de estas cepas. Abstract in english ABSTRACT This work is part of a megaproject that seeks to isolate microalgae of the Chlorophyta division native to Norte de Santander and identify their potential applications such as lipid production to be used as biofuel. Here we present the isolation of 11 microalgae strains from the Chlorophyta division found in two different wastewater environments. The collected strains were cultivated in selective media and purified through serial dilutions, depletion culture, and (more) application of penicillin and gentamicin. Biomass production was evaluated and two strains were selected: CHL1 (Chlorella sp.) and DES1 (Desmodesmus sp.). The strains were cultivated on wastewater and PCG media (control), and their biomass concentration and lipid content were measured. Both strains reached similar biomass concentrations compared to their respective controls (CHL1 PCG 1.5 mg/L ± 0.035 mg/L, CHL1 AR 1.68 mg/L ± 0.036, DES1 PCG 1.66 mg/L ± 0.007, DES1 AR 2 mg/L ± 0.03) and their lipid content was slightly higher compared to their controls. The results show that the isolated and evaluated strains may have potential to be lipid producers, since their environmental and nutritional conditions have not been modified yet and adaptation may improve the production yield of lipids.

Culturing Selenastrum capricornutum (Chlorophyta) in a synthetic algal nutrient medium with defined mineral particulates  

Science.gov (United States)

Algal nutrient studies in chemically-defined media typically employ a synthetic chelator to prevent iron hydroxide precipitation. Micronutrient-particulate interactions may, however, significantly affect chemical speciation and hence biovailability of these nutrients in natural waters. A technique is described by which Selenastrum capricornutum Printz (Chlorophyta) may be cultured in a medium where trace metal speciation (except iron) is controlled, not by organic chelation, but by sorption onto titanium dioxide. Application of this culturing protocol in conjunction with results from sorption studies of nutrient ions on mineral particles provides a means of studying biological impacts of sorptive processes in aquatic environments. ?? 1985 Dr W.

Bibliotecas digitales: recursos bibliográficos electrónicos en educación básica Digital Libraries: Electronic Bibliographic Resources on Basic Education  

Directory of Open Access Journals (Sweden)

Full Text Available Estudiar recursos bibliográficos en formato electrónico para la educación básica implica reflexionar sobre mecanismos de búsqueda que atiendan las necesidades de los pequeños usuarios. A través de los trabajos realizados en el proyecto de investigación educativa «Bibliotecas digitales», se puso en evidencia que los acervos explorados, manejan un lenguaje para un nivel de educación superior. Ante esta problemática, se planteó la siguiente pregunta de investigación: ¿Cuáles son los criterios de clasificación de los recursos bibliográficos electrónicos para la educación básica? Se propuso una investigación no experimental, con una muestra de estudio no probabilística de casos tipo, integrada por 250 recursos que ofrecen los diez acervos bibliográficos seleccionados en base a un estudio exploratorio previamente realizado. Para el análisis, se valoraron los siguientes recursos: accesibilidad, eje curricular al que está dirigido, formato y aspectos pedagógicos, funcionales, tecnológicos y estéticos. Los resultados muestran una media de 3.76, la cual indica que los acervos bibliográficos ofrecen recursos de calidad, aunque es necesario trabajar en los aspectos pedagógicos y funcionales. Clasificar recursos electrónicos para educación básica requiere considerar necesidades pedagógicas, entorno gráfico, tecnológico y sobre todo, la forma dinámica y cambiante de cómo se concibe la información. Esto corrobora la necesidad de establecer un conjunto de indicadores que permita a los docentes seleccionar recursos electrónicos en relación a los ejes curriculares de la educación básica.Studying electronic bibliographic resources for basic education involves thinking about search mechanisms that meet the needs of young users. Through the investigation carried out during the educational research project «Digital libraries», it became evident that the collections explored use a language better suited to higher education. Faced with this problem, the following question arose: What are the criteria for classifying electronic bibliographic resources for basic education? The proposed investigation was non-experimental, with a non-probabilistic sample of case studies; the sample comprised 250 resources from 10 bibliographic collections. The analysis assessed resources according to: accessibility, the curricular axis to which it is addressed, and format; pedagogical, functional, technological and aesthetic aspects. The results show a mean of 3.76, which indicates that the bibliographic collections provide quality resources, although it is necessary to improve educational and functional aspects. Classifying electronic resources for basic education requires the consideration of pedagogical needs, graphical and technological qualities and, especially, the dynamic way in which information is conceived nowadays. This confirms the need to establish a set of indicators that enable teachers to select electronic resources based on basic education curricular axes.

Extra and intracelular activities of carbonic anhydrase of the marine microalga Tetraselmis gracilis (Chlorophyta) Atividade extra e intracelular da Anidrase Carbônica na microalga marinha Tetraselmis gracilis (Chlorophyta)  

Directory of Open Access Journals (Sweden)

Full Text Available The activities of extra and intracellular carbonic anhydrases (CA) were studied in the microalgae Tetraselmis gracilis (Kylin) Butcher (Chlorophyta, Prasinophyceae) growing in laboratory cultivation. During ten days of batch cultivation, daily determinations of pH, cell number, enzymatic activity, and total dissolved inorganic carbon (DIC), as well as its main species, CO2 and HCO3-, were performed. Enzymatic activity increased as the growing cell population depleted inorganic carbon from the medium. Carbon dioxide concentration decreased quickly, especially in the third day of cultivation, when a significant increase of the intracellular enzymatic activity was observed. Bicarbonate concentration had its largest decrease in the cultivation medium in the fourth day, when the activity of the extracellular enzyme had its largest increase, suggesting its use by the alga through CA activity. After the fourth cultivation day, half of the cultures were aerated with CO2-free atmospheric air, which caused an increase in the total and external activity of the enzyme, although, in this condition, the stationary growth phase began earlier than in cultures aerated with atmospheric air. The pH of the media was measured daily, increasing from the first to the fourth day, and remaining almost constant until the end of the cultivation. Algal material transferred to the dark lost all enzymatic activity.As atividades da Anidrase Carbônica (AC) extra e intracelular foram estudadas na microalga marinha Tetraselmis gracilis (Kylin) Butcher (Chlorophyta, Prasinophyceae) crescendo em cultivos laboratoriais. Durante dez dias de cultivo, determinações diárias do pH, número de células, atividades enzimáticas, carbono inorgânico total dissolvido (CID) e suas principais espécies CO2 e HCO3- foram feitas. A atividade enzimática aumentou na medida em que a população celular em crescimento retirava carbono inorgânico do meio de cultivo. A concentração de dióxido de carbono decresceu rapidamente, especialmente no terceiro dia do cultivo, quando um significante aumento na atividade enzimática intracelular foi observado. A concentração de bicarbonato teve seu maior decréscimo no meio de cultivo no quarto dia, quando a atividade da enzima extracelular teve seu maior aumento, sugerindo seu uso pela alga através da atividade da AC. Após o quarto dia de cultivo, metade das culturas passou a ser aerada com ar atmosférico sem CO2, o que causou um aumento na atividade total e externa da enzima, fazendo com que esses cultivos entrassem na fase estacionária do crescimento antes que aqueles aerados com ar atmosférico normal. O pH do meio foi medido diariamente, aumentando desde o primeiro até o quarto dia e permanecendo quase constante até o fim do cultivo. Material algal transferido para o escuro perdeu toda a atividade enzimática.

Cell shape in the alga Pediastrum (Hydrodictyaceae; Chlorophyta)  

Energy Technology Data Exchange (ETDEWEB)

Species of Pediastrum, a genus in which the colonies assemble from aggregating zoospores, differ in the number and form of prongs on peripheral cells and the amount of space between cells of the colony; cell shape appears to be genetically based. Peripheral cells of the P. boryanum colony, for example, have two prongs per cell; P. simplex has one prong per cell. Prong extension is suppressed in the interior cells of P. boryanum, but prong sites have been reported in scanning electron micrographs of the cell walls. A mutant unicellular strain in which cells of the colony separate after attaining typical form reveals several prong sites (6 or more) in each cell. Multiple suppressed prong sites are evident in P. simplex cells as well. Polyeders, 4- 5-pronged unicells, occur in the life cycle of P. simplex. Based on these observations and a recent report by Marchant (1979) of a microtubule organizing center associated with the prongs, it is suggested that several microtubule organizing centers are to be found in zoospores of Pediastrum species and may be related to species differences in cell shape.

Review of material recovery from used electric and electronic equipment-alternative options for resource conservation.  

UK PubMed Central (United Kingdom)

For waste from electric and electronic equipment, the WEEE Directive stipulates the separate collection of electric and electronic waste. As to new electric and electronic devices, the Restriction of Hazardous Substances (RoHS) Directive bans the use of certain chemicals dangerous for man and environment. From the implementation of the WEEE directive, many unsolved problems have been documented: poor collection success, emission of dangerous substances during collection and recycling, irretrievable loss of valuable metals among others. As to RoHS, data from the literature show a satisfying success. The problems identified in the process can be reduced to some basic dilemmas at the borders between waste management, product policy and chemical safety. The objectives of the WEEE Directive and the specific targets for use and recycling of appliances are not consistent. There is no focus on scarce resources. Extended producer responsibility is not sufficient to guarantee sustainable waste management. Waste management reaches its limits due to problems of implementation but also due to physical laws. A holistic approach is necessary looking at all branch points and sinks in the stream of used products and waste from electric and electronic equipment. This may be done with respect to the general rules for sustainable management of material streams covering the three dimensions of sustainable policy. The relationships between the players in the field of electric and electronic devices have to be taken into account. Most of the problems identified in the implementation process will not be solved by the current amendment of the WEEE Directive.

A preliminary categorization of end-of-life electrical and electronic equipment as secondary metal resources  

International Nuclear Information System (INIS)

[en] Highlights: ? End-of-life electrical and electronic equipment (EEE) as secondary metal resources. ? The content and the total amount of metals in specific equipment are both important. ? We categorized 21 EEE types from contents and total amounts of various metals. ? Important equipment types as secondary resources were listed for each metal kind. ? Collectability and possible collection systems of various EEE types were discussed. - Abstract: End-of-life electrical and electronic equipment (EEE) has recently received attention as a secondary source of metals. This study examined characteristics of end-of-life EEE as secondary metal resources to consider efficient collection and metal recovery systems according to the specific metals and types of EEE. We constructed an analogy between natural resource development and metal recovery from end-of-life EEE and found that metal content and total annual amount of metal contained in each type of end-of-life EEE should be considered in secondary resource development, as well as the collectability of the end-of-life products. We then categorized 21 EEE types into five groups and discussed their potential as secondary metal resources. Refrigerators, washing machines, air conditioners, and CRT TVs were evaluated as the most important sources of common metals, and personal computers, mobile phones, and video games were evaluated as the most important sources of precious metals. Several types of small digital equipment were also identified as important sources of precious metals; however, mid-size information and communication technology (ICT) equipment (e.g., printers and fax machines) and audio/video equipment were shown to be more important as a source of a variety of less common metals. The physical collectability of each type of EEE was roughly characterized by unit size and number of end-of-life products generated annually. Current collection systems in Japan were examined and potentially appropriate collection methods were suggested for equipment types that currently have no specific collection systems in Japan, particularly for video games, notebook computers, and mid-size ICT and audio/video equipment.

Achieving Resource Conservation in Electronic Waste Management: A Review of Options Available to Developing Countries  

Directory of Open Access Journals (Sweden)

Full Text Available Large quantities of waste electronic devices (e-waste) at their end-of-life, generated internally or imported illegally from developed countries, are currently being managed in the developing countries, through low-end means such as crude backyard recycling and disposal at unlined landfills or open dumps. The extension of the lifespan of electronic devices through reuse options such as repair, reconditioning and remanufacturing should be a priority in the management of electronic waste in developing countries considering the near absence of state-of-the-art recycling facilities in these countries. Life extension through product and component reuse is especially critical to electronic products because in recent years, electronics have increased in technological complexity, with new product innovations and ever shortening product life expectancy. For many products, environmentalists assume that reuse is environmentally beneficial because it replaces the manufacturing and purchase of new goods. However, on the contrary, manufacturers may oppose this type of reuse for the same reason. There is an urgent need to control the trans-boundary movement of electronic scrap especially to countries without established recycling facilities. Importations of secondhand electronics make such devices available to those who cannot afford new products. However, an international method of testing and certification is needed to ensure that exported secondhand devices are functional. Establishment of formal recycling facilities for e-waste in the developing countries will ensure resource reutilization with both economical and ecological gains. This study reviews options available in working towards eco-efficient management of e-waste in developing countries in the light of the present low-end management practices.

Reducing Clinical Trial Monitoring Resource Allocation and Costs Through Remote Access to Electronic Medical Records  

Science.gov (United States)

Purpose: With electronic medical records (eMRs), the option now exists for clinical trial monitors to perform source data verification (SDV) remotely. We report on a feasibility study of remote access to eMRs for SDV and the potential advantages of such a process in terms of resource allocation and cost. Methods: The Clinical Trials Unit at the Peter MacCallum Cancer Centre, in collaboration with Novartis Pharmaceuticals Australia, conducted a 6-month feasibility study of remote SDV. A Novartis monitor was granted dedicated software and restricted remote access to the eMR portal of the cancer center, thereby providing an avenue through which perform SDV. Results: Six monitoring visits were conducted during the study period, four of which were performed remotely. The ability to conduct two thirds of the monitoring visits remotely in this complex phase III study resulted in an overall cost saving to Novartis. Similarly, remote monitoring eased the strain on internal resources, particularly monitoring space and hospital computer terminal access, at the cancer center. Conclusion: Remote access to patient eMRs for SDV is feasible and is potentially an avenue through which resources can be more efficiently used. Although this feasibility study involved limited numbers, there is no limit to scaling these processes to any number of patients enrolled onto large clinical trials.

ELLIPTOCHLORIS MARINA SP. NOV. (TREBOUXIOPHYCEAE, CHLOROPHYTA), SYMBIOTIC GREEN ALGA OF THE TEMPERATE PACIFIC SEA ANEMONES ANTHOPLEURA XANTHOGRAMMICA AND A. ELEGANTISSIMA (ANTHOZOA, CNIDARIA)  

UK PubMed Central (United Kingdom)

Symbiotic green algae from two species of intertidal Pacific sea anemones, Anthopleura elegantissima and Anthopleura xanthogrammica, were collected from the northeastern Pacific coast of North America across the known range of the symbiont. Freshly isolated Anthopleura symbionts were used for both morphological and molecular analyses because Anthopleura symbiont cultures were not available. Light and transmission electron microscopy supported previous morphological studies, showing the symbionts consist of spherical unicells from 5 to 10 ?m in diameter, with numerous vesicles, and a single bilobed chloroplast. Pyrenoids were not seen in LM, but a thylakoid-free area was observed in TEM, consistent with previous findings. Many algal cells extracted from fresh anemone tissue were observed in the process of division, producing two autospores within a maternal cell wall. The morphology of the green symbionts matches that of Elliptochloris Tscherm.-Woess. Molecular phylogenetic analyses of the nuclear SSU rDNA and the plastid encoded gene for the large subunit of RUBISCO (rbcL) support the monophyly of these green algal symbionts, regardless of host species and geographic origin. Phylogenetically, sequences of the Anthopleura symbionts are nested within the genus Elliptochloris and are distinct from sequences of all other Elliptochloris spp. examined. Given the ecological and phylogenetic distinctions among the green algal symbionts in Anthopleura spp. and the named species of Elliptochloris, we designate the green algal symbionts as a new species, Elliptochloris marina (Trebouxiophyceae, Chlorophyta).

Use of Electronic Information Resources and Research Output by Academic Staff in Private Universities in Ogun State, Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available The study examined the use of electronic information resources and research output by academic staff in private universities in Ogun state, Nigeria. Three private universities were selected out of the nine private universities in Ogun state. These universities are Crescent University, Abeokuta, Babcock University, Ilishan-Remo, and Redeemers’ University, Mowe, all in Ogun State, Nigeria. Purposive sampling method was used to investigate respondents. The instrument used for data collection was structured questionnaire. 225 copies of the questionnaire were administered at Babcock University and 144 were retrieved. 88 at Crescent University and 80 were retrieved, while 215 at the Redeemers’ University and 130 were retrieved. The research looked at the extent with which electronic information resources were used in the private universities in Ogun State, using the three universities as sample. A total of 528 copies of the questionnaire were distributed to the respondents at the three universities and a valid number of 354 (66%) questionnaires were retrieved and analyzed. The questionnaire was designed using nominal and likert scales. The study revealed that most of the academic staff from the three private universities knew and used electronic information resources for their research work as shown on Tables 5, 6, 7 and 8. Findings from Tables 8 and 9 indicate that most of respondents from the three private universities have published their articles and presented papers with the use of electronic information resources. The study also revealed on Table 6 that effective use of electronic information resources contribute to the academics’ research output hence 329 (92.9%) of the total respondents supported that view. It is imperative to state here that lack of personal computer and erratic power supply among others are major constraints that inhibit use of electronic information resources in the three private universities which invariably affects their research output. The researchers recommended that private universities in Nigeria expedite action in the area of improving access to electronic information resources through provision of subsidized computers and improved electricity supply in their various universities. Moreso, academic staff are advised to acquire computer skills, learn and relearn to navigate and utilize the vast available electronic information resources on the internet to achieve better research output.Key words: Electronic information resources; Research output; Academics; Information access; Information skill; ICT; Electronic journal; Private university; Ogun state

Inhibition of growth of Ulva expansa (chlorophyta) by ultraviolet-B radiation  

International Nuclear Information System (INIS)

We examined the effect of ultraviolet-B radiation (UV-B, 290-320 nm) on the growth rate of the intertidal marine alga Ulva expansa (Setch.) S ampersand G. (Chlorophyta). Segments of thallus collected from a natural population were grown in outdoor seawater tanks. Combinations of UV-B-opaque screens, UV-B transparent screens, and UV-B lamps were used to investigate the effects of solar UV-B and solar plus supplemental UV-B on the growth of these segments. Growth was measured by changes in segment surface area, damp weight, and dry weight. Growth rates of segments were inhibited under both solar UV-B and solar plus supplemental UV-B treatments. Growth rates were also inhibited by high levels of photosynthetically active radiation, independent of UV-B fluence. These results indicate that increases in UV-B resulting from further ozone depletion will have a negative impact on the growth of this alga. 32 refs., 5 figs., 2 tabs.

The Impact of Electronic Banking on Human Resources Performance in the Nigerian Banking Industry  

Directory of Open Access Journals (Sweden)

Full Text Available The survey examined the impact of electronic banking on Human Resource (HR) performance in the Nigerian banking industry, using First Bank Plc as a case study. The objective was to determine how the introduction of e-Banking has impacted on the efficiency and effectiveness of service delivery by the bank's personnel and on bank-customers relationship and customer satisfaction. Structured questionnaire was used with the aid of personal interview to collect data from thirty five respondents randomly sampled from five purposively selected branches of First Bank Plc. Chi-square test was applied for data analysis. Result showed among other things that introduction of electronic banking has impacted positively on the bank's HR performance, in terms of improved efficiency and effectiveness of service delivery by bank personnel. Bank-customer relationship and customers’ satisfaction was also found to have been greatly enhanced. Hence, Government should lower the tariff on information technology-aided tools and equipment imported and possibly subsidized the cost.

Effects of acid stress on Scenedesmus quadricauda (chlorophyta) and Anabaena sp. (cyanophyta)  

Energy Technology Data Exchange (ETDEWEB)

The effects of pH in conjunction with light and temperature on growth of Scenedesmus quadricauda (Chlorophyta) and Anabaena sp. (Cyanophyta) were examined in culture. Decreasing pH from 7 to 3 inhibited growth, more so in the blue-green alga. Effects were greatly influenced by light and temperature. Above a critical level (pH4 with the blue-green, pH 3 with the green) both algae recovered when acid stress was removed; post-acidification growth rates varied inversely with pH for the green alga and directly for the blue-green. Two sheathed blue-green algae (Lyngbya and Gleocapsa) grew below pH 6, while two unsheathed blue-green algae (Anabaena and Oscillatoria) did not. Cell dimensions of both S. quadricaude and Anabaena sp. generally increased as pH declined; the green alga was the more plastic of the two. Acid stress significantly decreased photosynthetic rate in S. quadricauda but did not for Anabaena sp. Respiratory rates were not significantly related to pH for either alga. Chlorophyll a per cell was higher than controls (pH 7) at pH 5 and 6 in Anabaena sp. and at pH 4 through 6 for S. quadricauda. Both cell division and total culture biomass declined with pH. When grown in mixed culture, the green alga usually predominated at pH 4 and often at pH 5; the blue-green was favored at lower light intensities and higher temperatures. In no instance did one alga stimulate growth of the other, although mutual inhibition occurred in several instances.

ANALYSIS OF A PLASTID MULTIGENE DATA SET AND THE PHYLOGENETIC POSITION OF THE MARINE MACROALGA CAULERPA FILIFORMIS (CHLOROPHYTA)  

UK PubMed Central (United Kingdom)

Molecular phylogenetic relationships within the Chlorophyta have relied heavily on rRNA data. These data have revolutionized our insight in green algal evolution, yet some class relationships have never been well resolved. A commonly used class within the Chlorophyta is the Ulvophyceae, although there is not much support for its monophyly. The relationships among the Ulvophyceae, Trebouxiophyceae, and Chlorophyceae are also contentious. In recent years, chloroplast genome data have shown their utility in resolving relationships between the main green algal clades, but such studies have never included marine macroalgae. We provide partial chloroplast genome data (~30,000 bp, 23 genes) of the ulvophycean macroalga Caulerpa filiformis (Suhr) K. Herig. We show gene order conservation for some gene combinations and rearrangements in other regions compared to closely related taxa. Our data also revealed a pseudogene (ycf62) in Caulerpa species. Our phylogenetic results, based on analyses of a 23-gene alignment, suggest that neither Ulvophyceae nor Trebouxiophyceae are monophyletic, with Caulerpa being more closely related to the trebouxiophyte Chlorella than to Oltmannsiellopsis and Pseudendoclonium.

Systematically assessing the situational relevance of electronic knowledge resources: a mixed methods study.  

UK PubMed Central (United Kingdom)

UNLABELLED: Electronic Knowledge Resources (EKRs) are increasingly used by physicians, but their situational relevance has not been systematically examined. OBJECTIVE: Systematically scrutinize the situational relevance of EKR-derived information items in and outside clinical settings. BACKGROUND: Physicians use EKRs to accomplish four cognitive objectives (C1-4), and three organizational objectives (O1-3): (C1) Answer questions/solve problems/support decision-making in a clinical context; (C2) fulfill educational-research objectives; (C3) search for personal interest or curiosity; (C4) overcome limits of human memory; (O1) share information with patients, families, or caregivers; (O2) exchange information with other health professionals; (O3) plan-manage-monitor tasks with other health professionals. METHODS: Longitudinal mixed methods multiple case study: Cases were 17 residents' critical searches for information, using a commercial EKR, during a 2-month block of family practice. Usage data were automatically recorded. Each "opened" item of information was linked to an impact assessment questionnaire, and 1,981 evaluations of items were documented. Interviews with residents were guided by log files, which tracked use and impact of EKR-derived information items. Thematic analysis identified 156 critical searches linked to 877 information items. For each case, qualitative data were assigned to one of the seven proposed objectives. RESULTS: Residents achieved their search objectives in 85.9% of cases (situational relevance). Additional sources of information were sought in 52.6% of cases. Results support the seven proposed objectives, levels of comparative relevance (less, equally, more), and levels of stimulation of learning and knowledge (individual, organizational). CONCLUSION: Our method of systematic assessment may contribute to user-based evaluation of EKRs.

Human resource requirements for quality-assured electronic data capture of the tuberculosis case register  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background The tuberculosis case register is the data source for the reports submitted by basic management units to the national tuberculosis program. Our objective was to measure the data entry time required to complete and double-enter one record, and to estimate the time for the correction of errors in the captured information from tuberculosis case registers in Cambodia and Viet Nam. This should assist in quantifying the additional requirements in human resources for national programs moving towards electronic recording and reporting. Methods Data from a representative sample of tuberculosis case registers from Cambodia and Viet Nam were double-entered and discordances resolved by rechecking the original case register. Computer-generated data entry time recorded the time elapsed between opening of a new record and saving it to disk. Results The dataset comprised 22,732 double-entered records of 11,366 patients (37.1% from Cambodia and 62.9% from Viet Nam). The mean data entry times per record were 97.5 (95% CI: 96.2-98.8) and 66.2 (95% CI: 59.5-73.0) seconds with medians of 90 and 31 s respectively in Cambodia and in Viet Nam. The percentage of records with an error was 6.0% and 39.0% respectively in Cambodia and Viet Nam. Data entry time was inversely associated with error frequency. We estimate that approximately 118-person-hours were required to produce 1,000 validated records. Conclusions This study quantifies differences between two countries for data entry time for the tuberculosis case register and frequencies of data entry errors and suggests that higher data entry speed is partially offset by requiring revisiting more records for corrections.

Challenges in the implementation of an electronic surveillance system in a resource-limited setting: Alerta, in Peru  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Infectious disease surveillance is a primary public health function in resource-limited settings. In 2003, an electronic disease surveillance system (Alerta) was established in the Peruvian Navy with support from the U.S. Naval Medical Research Center Detachment (NMRCD). Many challenges arose during the implementation process, and a variety of solutions were applied. The purpose of this paper is to identify and discuss these issues. Methods This is a retrospective description of the Alerta implementation. After a thoughtful evaluation according to the Centers for Disease Control and Prevention (CDC) guidelines, the main challenges to implementation were identified and solutions were devised in the context of a resource-limited setting, Peru. Results After four years of operation, we have identified a number of challenges in implementing and operating this electronic disease surveillance system. These can be divided into the following categories: (1) issues with personnel and stakeholders; (2) issues with resources in a developing setting; (3) issues with processes involved in the collection of data and operation of the system; and (4) issues with organization at the central hub. Some of the challenges are unique to resource-limited settings, but many are applicable for any surveillance system. For each of these challenges, we developed feasible solutions that are discussed. Conclusion There are many challenges to overcome when implementing an electronic disease surveillance system, not only related to technology issues. A comprehensive approach is required for success, including: technical support, personnel management, effective training, and cultural sensitivity in order to assure the effective deployment of an electronic disease surveillance system.

First isolation of a Helicosporidium sp. (Chlorophyta: Trebouxiophyceae) from the biological control agent Cyrtobagous salviniae (Coleoptera: Curculionidae)  

UK PubMed Central (United Kingdom)

Cyrtobagous salviniae (Coleoptera: Curculionidae) is a weevil that has been introduced into at least 16 countries as a biological control agent for the floating fern, Salvinia molesta. Screening in Florida of C. salviniae imported from South Africa found a pathogen identified as a previously unknown species of Helicosporidium (Chlorophyta: Trebouxiophyceae). Fresh cysts measured 5.1 x 4.8 ?m and ultrastructural examination demonstrated the presence of three ovoid cells surrounded by a filamentous cell. Cysts of this pathogen were isolated and transmitted to the alternate hosts Helicoverpa zea and Anopheles quadrimaculatus. This is the first report of a pathogen from C. salviniae and demonstrates the need for and value of screening and monitoring biological control agents for pathogens prior to introduction. Releasing healthy C. salviniae not only enhances the chances for successful control of S. molesta but also reduces the risk for the inadvertent introduction of pathogens that may have undesirable and unexpected impacts on native fauna.

Preference and Use of Electronic Information and Resources by Blind/Visually Impaired in NCR Libraries in India  

Directory of Open Access Journals (Sweden)

Full Text Available This paper aims to determine the preference and use of electronic information and resources by blind/visually impaired users in the leading National Capital Region (NCR) libraries of India. Survey methodology has been used as the basic research tool for data collection with the help of questionnaires. The 125 in total users surveyed in all the five libraries were selected randomly on the basis of willingness of the users with experience of working in digital environments to participate in the survey. The survey results were tabulated and analyzed with descriptive statistics methods using Excel software and 'Stata version 11'. The findings reveal that ICT have a positive impact in the lives of people with disabilities as it helps them to work independently and increases the level of confidence among them. The Internet is the most preferred medium of access to information among the majority of blind/visually impaired users. The 'Complexity of content available on the net' is found as the major challenge faced during Internet use by blind users of NCR libraries. 'Audio books on CDs/DVDs and DAISY books' are the most preferred electronic resources among the majority of blind/visually impaired users. This study will help the library professionals and organizations/institutions serving people with disabilities to develop effective library services for blind/visually impaired users in the digital environment on the basis of findings on information usage behavior in the study.

Photosynthetic characteristics of a tropical population of Nitella cernua (Characeae, Chlorophyta) Características fotossintéticas de uma população tropical de Nitella cernua (Characeae, Chlorophyta)  

Directory of Open Access Journals (Sweden)

Full Text Available Photosynthetic characteristics (assessed by chlorophyll fluorescence and O2 evolution) were analysed monthly during one year in a tropical population of Nitella cernua from southeastern Brazil (20º50'32" S, 49º26'15" W). Parameters derived from photosynthesis-irradiance (PI) curves by fluorescence (high values of the photosynthetic parameter, Ik, and lack or low values of photoinhibition, beta) suggested adaptation to high irradiance, whereas those by O2 evolution showed a different pattern (low values of Ik and compensation irradiance, Ic, high values of photosynthetic efficiency, alpha, and photoinhibition). Parameters from PI curves by O2 evolution suggested light acclimation: Ik and maximum photosynthetic rate, Pmax (as rETR, relative electron transfer rate) increased, whereas a became significantly lower under higher irradiance (winter). This pattern is an adjustment of both number and size of photosynthetic units. Photosynthetic performance assessed by fluorescence revealed two seasonal periods: higher values of Pmax (rETR), Ik and non-photochemical quenching from October to March (rainy season), and lower values from April to October (dry season). Temperature responses were observed only in summer, but temperature optima were different between methods: peaks of net photosynthesis occurred at 20ºC, whereas rETR increased towards higher temperatures (up to 30ºC). Dark respiration increased with higher temperatures. Current velocity had a stimulatory effect on photosynthetic rates, as suggested by positive correlations with Pmax (rETR) and alpha. pH experiments revealed highest net photosynthetic rates under pH 4.0, suggesting higher affinity for CO2 than HCO3-. This broad range of responses of photosynthetic characteristics of this N. cernua population to irradiance, temperature, and pH/inorganic carbon reflects a wide tolerance to variations in these environmental variables, which probably contribute to the wide distribution of this species.Foram analisadas mensalmente, durante um ano, as características fotossintéticas (por meio de fluorescência da clorofila e evolução de O2) de uma população tropical de Nitella cernua do sudeste do Brasil (20º50'32" S, 49º26'15" W). Parâmetros derivados das curvas fotossíntese-irradiância (FI) por fluorescência (alto valor do parâmetro de saturação de luz, Ik, e ausência ou baixa fotoinibição, b) sugeriram adaptação a alta irradiância, enquanto aqueles por evolução de oxigênio mostraram adaptações à sombra (baixo valores de Ik e de irradiância de compensação, Ic , altos valores de eficiência fotossintética, alfa, e beta). Parâmetros das curvas FI por oxigênio sugeriram aclimatação à luz: Ik e taxa fotossintética máxima, Fmax (analisada como rETR, taxa relativa de transporte de elétrons) aumentaram e a foi significativamente menor sob irradiância mais alta (inverno). Este padrão é um ajuste pelo número e tamanho das unidades fotossintéticas. O desempenho fotossintético avaliado por fluorescência revelou dois períodos sazonais: maiores valores de Fmax, Ik e extinção não-fotoquímica, de outubro a março, e menores, de abril a outubro. Respostas de temperatura foram observadas apenas no verão, mas ótimos de temperatura foram diferentes: picos de fotossíntese líquida ocorreram a 20ºC, enquanto rETR aumentou com temperaturas mais altas (até 30ºC). A respiração no escuro aumentou com a elevação da temperatura. Velocidade da correnteza teve presumivelmente papel estimulatório sobre as taxas fotossintéticas, como sugerido pelas correlações positivas com Fmax e alfa. Experimentos de pH revelaram taxas fotossintéticas mais altas em pH 4,0, sugerindo maior afinidade por CO2. Essas amplas respostas das características fotossintéticas da população de N. cernua à irradiância, à temperatura e ao pH/carbono inorgânico refletem grande tolerância a variações dessas variáveis ambientes, que, provavelmente, contribuem para a extensa distribuição de N. cernua.

Functional sulfur amino acid production and seawater remediation system by sterile Ulva sp. (Chlorophyta).  

Science.gov (United States)

Sterile Ulva, which is a macroalga, has the potential to grow stably; therefore, this seaweed is expected to be an efficient resource of functional food containing various nutrients such as sulfur amino acids, proteins, carbohydrates, and minerals. Ulva latuca was selected from the "Marine Park" in Tokyo Bay, and its growth rate (g-dry/[m2.d]) was measured using model reactors located on the land or on the surface of the sea at Yokohama. The growth rate of U. lactuca was recorded to be approx 20 g-dry/(m2.d), which is estimated to be 10 times greater than that in a natural field in the Marine Park. In addition, this growth rate was higher than that of conventional crops such as corn and rice on a farm or paddy. These data led us to newly design and propose a floating type of labor-efficient U. lactuca production system. d-Cysteinolic acid, which is included in U. lactuca as a major sulfur amino acid, inhibited the Fenton reaction, resulting in suppression of hydroxyl radical production and singlet oxygen. Addition of the sulfur amino acid (1 microM) to HepG2 cells markedly decreased the intracellular triglyceride level. Hence, this proposed facility also has the potential for industrial production of a valuable resource for the primary prevention of lifestyle-related diseases using enriched or eutrophied seawater.

Innovative direct energy conversion systems using electronic adiabatic processes of electron fluid in solid conductors: new plants of electrical power and hydrogen gas resources without environmental pollutions  

Energy Technology Data Exchange (ETDEWEB)

It is shown that using a novel recycling process of the environmental thermal energy, innovative permanent auto-working direct energy converter systems (PA-DEC systems) from the environmental thermal to electrical and/or chemical potential (TE/CP) energies, abbreviated as PA-TE/CP-DEC systems, can be used for new auto-working electrical power plants and the plants of the compressible and conveyable hydrogen gas resources at various regions in the whole world, with contributions to the world peace and the economical development in the south part of the world. It is shown that the same physical mechanism by free electrons and electrical potential determined by temperature in conductors, which include semiconductors, leads to the Peltier effect and the Seebeck one. It is experimentally clarified that the long distance separation between two {pi} type elements of the heat absorption (HAS) and the production one (HPS) of the Peltier effect circuit system or between the higher temperature side (HTS) and the lower one (LTS) of the Seebeck effect circuit one does not change in the whole for the both effects. By using present systems, we do not need to use petrified fuels such as coals, oils, and natural gases in order to decrease the greenhouse effect by the CO{sub 2} surrounding the earth. Furthermore, we do not need plats of nuclear fissions that left radiating wastes, i.e., with no environmental pollutions. The PA-TE/CP-DEC systems can be applicable for several km scale systems to the micro ones, such as the plants of the electrical power, the compact transportable hydrogen gas resources, a large heat energy container, which can be settled at far place from thermal energy absorbing area, the refrigerators, the air conditioners, home electrical apparatuses, and further the computer elements. It is shown that the simplest PA-TE/CP-DEC system can be established by using only the Seebeck effect components and the resolving water ones. It is clarified that the externally applied electrical energy is used only for the Joule heating in the total resistance of the circuit, and the transportation of heat energy takes place independently from the external electrical source. It is clarified that since we make the innovative PA-TE/CP-DEC systems in thermally open surroundings, the entropy theory established in the closed system is not applicable for the proposed systems.

Bioremediation of reject water from anaerobically digested waste water sludge with macroalgae (Ulva lactuca, Chlorophyta).  

UK PubMed Central (United Kingdom)

Phosphorus and biologically active nitrogen are valuable nutrient resources. Bioremediation with macroalgae is a potential means for recovering nutrients from waste streams. In this study, reject water from anaerobically digested sewage sludge was successfully tested as nutrient source for cultivation of the green macroalgae Ulva lactuca. Maximal growth rates of 54.57±2.16%FWd(-1) were achieved at reject water concentrations equivalent to 50?M NH4(+). Based on the results, the growth and nutrient removal was parameterised as function of NH4(+) concentration a tool for optimisation of any similar phycoremediation system. Maximal nutrient removal rates of 22.7mgNgDW(-1)d(-1) and 2.7mgPgDW(-1)d(-1) were achieved at reject water concentrations equivalent to 80 and 89?M NH4(+), respectively. A combined and integrated use of the produced biomass in a biorefinery is thought to improve the feasibility of using Ulva for bioremediation of reject water.

31P-NMR differentiation between intracellular phosphate pools in Cosmarium (chlorophyta)  

International Nuclear Information System (INIS)

31P nuclear magnetic resonance (NMR) spectroscopy of intact Cosmarium sp. cells is presented as a suitable tool for the differentiation of intracellular accumulation pools of polyphosphates. The cold trichloroacetic acid (TCA) insoluble fraction is shown to contain most of the total cellular phosphate in the phosphate rich Cosmarium cells. Moreover, evidence from a 31P-NMR study and electron microscopic observations of cold TCA treated Cosmarium cells indicate that this fraction consists mostly of polyphosphates which seem to retain the native morphological structure observed in the untreated cells. The determination of orthophosphate in the hot water extract of Cosmarium cells did not measure the polyphosphate pools. Determination of total phosphorus content in the hot water extract rendered a value three times higher than the frequently used orthophosphate determination procedure. However, as revealed by the 31P-NMR spectra and the chemical analyses of the extract and of the treated cells, even total phosphorus in the extract measured only 30% of the total cellular phosphorus. 31P-NMR enabled the unequivocal chemical identification of the major phosphate compounds in the hot water extract (Surplus P) as orthophosphate and polyphosphates of about 10 phosphate units chainlength. More than 70% of the accumulation pool of polyphosphates was still in the cells after extraction. However, the electron microscopy study revealed that the native granular structure of polyphosphates had been destroyed by the hot water extraction procedure

Taxonomic significance of micromorphology and dimensions of oospores in the genus Chara L., Charales, Chlorophyta  

Directory of Open Access Journals (Sweden)

Full Text Available Oospore wall ornamentation patterns as revealed by scanning electron microscopy (SEM) provide important taxonomic characters in the Charales. The present study illustrates inter- and intra-specific variations in the oospore wall ornamentation of five species of Chara, including eight intra-specific taxa. The type variety and form of C. globularis shows pusticular elevations with pores at the base of the elevation. The variety and form aspera of C. globularis shows a porous oospore wall, and the oospore is provided with a ribbon which bears nearly granular ornamentation. The type form of C. setosa has a granular oospore wall. The three forms of C. braunii show a similar type of ornamentation and support their placement under a single species. Chara corallina has a roughened oospore wall. Oospore dimensions studied at the population level are another feature included in the present study. The oospore dimension data (length, width fossa-breadth, number of striae) at the population level were analyzed statistically, and the results show species-specificity of these parameters. The significance of oospore wall ornamentation and dimensions are discussed simultaneously with morphological features.

Cleavage, incomplete inversion, and cytoplasmic bridges in Gonium pectorale (Volvocales, Chlorophyta).  

UK PubMed Central (United Kingdom)

Multicellularity arose several times in evolution of eukaryotes. The volvocine algae have full range of colonial organization from unicellular to colonies, and thus these algae are well-known models for examining the evolution and mechanisms of multicellularity. Gonium pectorale is a multicellular species of Volvocales and is thought to be one of the first small colonial organisms among the volvocine algae. In these algae, a cytoplasmic bridge is one of the key traits that arose during the evolution of multicellularity. Here, we observed the inversion process and the cytoplasmic bridges in G. pectorale using time-lapse, fluorescence, and electron microscopy. The cytoplasmic bridges were located in the middle region of the cell in 2-, 4-, 8-, and 16-celled stages and in inversion stages. However, there were no cytoplasmic bridges in the mature adult stage. Cytoplasmic bridges and cortical microtubules in G. pectorale suggest that a mechanism of kinesin-microtubule machinery similar to that in other volvocine algae is responsible for inversion in this species.

Search engines are typical in this category. Another category is the traditional library cataloging approach. For example, modified MARC formats are used to catalog the Internet resources. Besides these two, there are also some other ways to organize Internet resources, such as classification number schemes, subject heading systems, and other manual subject guides to provide a central access point for value-added topical guides. This paper introduces different approaches to organize Internet resources and focuses mainly on librarians' efforts.[Article content in Chinese

Freshwater Ulva (Chlorophyta) as a bioaccumulator of selected heavy metals (Cd, Ni and Pb) and alkaline earth metals (Ca and Mg).  

UK PubMed Central (United Kingdom)

We analyzed the ability of freshwater taxa of the genus Ulva (Ulvaceae, Chlorophyta) to serve as bioindicators of metal in lakes and rivers. Changes in heavy metal (Ni, Cd and Pb) and alkaline earth metal (Ca and Mg) concentrations in freshwater Ulva thalli were investigated during the period from June to August 2010. The study was conducted in two ecosystems in Western Poland, the Malta lake (10 sites) and the Nielba river (six sites). Three components were collected for each sample, including water, sediment and Ulva thalli. The average concentrations of metals in the water sample and in the macroalgae decreased in the following order: Ca>Mg>Ni>Pb>Cd. The sediment revealed a slightly altered order: Ca>Mg>Pb>Ni>Cd. Ca and Mg were found at the highest concentrations in thalli due to the presence of carbonate on its surface. Among the examined heavy metals in thalli, Ni was in the highest concentration, and Cd found in the lowest concentration. There were statistically significant correlations between the levels of metals in macroalgae, water and sediment. Freshwater populations of Ulva exhibited a greater efficiency to bioaccumulate nickel as compared to species derived from marine ecosystems.

The effect of electronic medical record-based clinical decision support on HIV care in resource-constrained settings: a systematic review.  

UK PubMed Central (United Kingdom)

BACKGROUND: It is estimated that one million people infected with HIV initiate anti-retroviral therapy (ART) in resource-constrained countries annually. This occurs against a background of overburdened health workers with limited skills to handle rapidly changing treatment standards and guidelines hence compromising quality of care. Electronic medical record (EMR)-based clinical decision support systems (CDSS) are considered a solution to improve quality of care. Little evidence, however, exists on the effectiveness of EMR-based CDSS on quality of HIV care and treatment in resource-constrained settings. OBJECTIVE: The aim of this systematic review was to identify original studies on EMR-based CDSS describing process and outcome measures as well as reported barriers to their implementation in resource-constrained settings. We characterized the studies by guideline adherence, data and process, and barriers to CDSS implementation. METHODS: Two reviewers independently assessed original articles from a search of the MEDLINE, EMBASE, CINAHL and Global Health Library databases until January 2012. The included articles were those that evaluated or described the implementation of EMR-based CDSS that were used in HIV care in low-income countries. RESULTS: A total of 12 studies met the inclusion criteria, 10 of which were conducted in sub-Saharan Africa and 2 in the Caribbean. None of the papers described a strong (randomized controlled) evaluation design. Guideline adherence: One study showed that ordering rates for CD4 tests were significantly higher when reminders were used. Data and process: Studies reported reduction in data errors, reduction in missed appointments, reduction in missed CD4 results and reduction in patient waiting time. Two studies showed a significant increase in time spent by clinicians on direct patient care. Barriers to CDSS implementation: Technical infrastructure problems such as unreliable electric power and erratic Internet connectivity, clinicians' limited computer skills and failure by providers to comply with the reminders are key impediments to the implementation and effective use of CDSS. CONCLUSION: The limited number of evaluation studies, the basic and heterogeneous study designs, and varied outcome measures make it difficult to meaningfully conclude on the effectiveness of CDSS on quality of HIV care and treatment in resource-limited settings. High quality evaluation studies are needed. Factors specific to implementation of EMR-based CDSS in resource-limited setting should be addressed before such countries can demonstrate its full benefits. More work needs to be done to overcome the barriers to EMR and CDSS implementation in developing countries such as technical infrastructure and care providers' computer illiteracy. However, simultaneously evaluating and describing CDSS implementation strategies that work can further guide wise investments in their wider rollout.

There is a Relationship between Resource Expenditures and Reference Transactions in Academic Libraries. A Review of: Dubnjakovic, A. (2012). Electronic resource expenditure and the decline in reference transaction statistics in academic libraries. Journal of Academic Librarianship, 38(2), 94-100. doi:10.1016/j.acalib.2012.01.001  

Directory of Open Access Journals (Sweden)

Full Text Available Objective – To provide an analysis of the impact of expenditures on electronic resourcesand gate counts on the increase or decrease in reference transactions.Design – Analysis of results of existing survey data from the National Center for Educational Statistics (NCES) 2006 Academic Library Survey(ALS).Setting – Academic libraries in the United States.Subjects – 3925 academic library respondents.Methods – The author chose to use survey data collected from the 2006 ALS conducted bythe NCES. The survey included data on various topics related to academic libraries, but in the case of this study, the author chose to analyze three of the 193 variables included. The three variables: electronic books expenditure, computer hardware and software, and expenditures on bibliographic utilities, were combined into one variable called electronic resource expenditure. Gate counts were also considered as a variable. Electronic resource expenditure was also split as a variable into three groups: low, medium, and high. Multiple regression analysis and general linear modeling, along with tests of reliability, were employed. Main Results – The author determined that low, medium, and high spenders with regard to electronic resources exhibited differences in gate counts, and gate counts have an effect on reference transactions in any given week. Gate counts tend to not have much of an effect on reference transactions for the higher spenders, and higher spenders tend to have a higher number of reference transactions overall. Low spenders have lower gate counts and also a lower amount of reference transactions.Conclusion – The findings from this study show that academic libraries spending more on electronic resources also tend to have an increase with regard to reference transactions. The author also concludes that library spaces are no longer the determining factor with regard to number of reference transactions. Spending more on electronic resources is also important to increase both in-person and electronic reference transactions.

COORDINATED CAROTENOID AND LIPID SYNTHESES INDUCED IN PARIETOCHLORIS INCISA (CHLOROPHYTA, TREBOUXIOPHYCEAE) MUTANT DEFICIENT IN ?5 DESATURASE BY NITROGEN STARVATION AND HIGH LIGHT  

UK PubMed Central (United Kingdom)

The responses to PAR intensity and nitrogen deficiency have been investigated in the ?5-desaturase-deficient mutant (P127) of the microalga Parietochloris incisa (Reisigl) Shin Watan. (Chlorophyta, Trebouxiophyceae). The mutant accumulates dihomo-?-linolenic acid (DGLA, C20:3 ?6) instead of arachidonic acid (C20:4 ?6) characteristic of the wildtype. The growth, fatty acid and pigment composition, and light absorption by P127 cell suspensions were studied for the first time during cultivation on complete and N-free BG-11 medium at 35, 130, and 270 ?E · m?² · s?¹. On complete medium under high irradiance, an increase in biomass was observed, and total fatty acid (TFA) and DGLA contents were higher than in N-starving cultures. A distinct irradiance-dependent rise in carotenoid-to-chl ratio was recorded in P127 due to an increase in carotenoids (on complete medium) or by a decline in chl (on N-free medium). Cultivation under high and medium irradiances caused a decline in light-harvesting xanthophylls and an increase in ?-carotene, localized predominantly in cytoplasmic oil bodies (OB). The P127 mutant, similar to wildtype, responded to the stresses by coordinated induction of fatty acid and carotenoid syntheses, but displayed the same magnitude of the response as was observed in wildtype under 30% lower irradiance. The changes in optical properties of the P127 cultures tightly correlated with their pigment composition, and hence with fatty acid content, making it possible to develop a nondestructive technique for the assay of TFA and DGLA. The peculiarities of the stress responses in the wildtype and the mutant are discussed.

Full Text Available Abstract in portuguese A fotoaclimatação da fotossíntese foi investigada numa população tropical de Cladophora glomerata (Estado de São Paulo, sudeste do Brasil, 20º 48? 24" S e 49º 22? 24" W) através de parâmetros de fluorescência da clorofila e conteúdo de clorofila a. As plantas foram aclimatadas a dois níveis de irradiância: baixa (65 ± 5 µmol.m-2.s-1) e alta (300 ± 10 :mol.m-2.s-1) e expostas a curto período (4 dias) e longo período (28 dias) em fotoperíod (more) o de 12 horas. Curvas de fotossíntese-irradiância (FI) revelaram estratégias distintas de fotoaclimatação. Plantas expostas a longo período aclimataram pela alteração do número de unidades fotossintéticas (UF) e mantiveram fixo o tamanho das UF. Estas características foram reveladas por menores taxas de fotossíntese máxima (Fmax), menor eficiência fotossintética (alfa) e valores mais altos do parâmetro de saturação (Ik) em alta irradiância. A estratégia de aclimatação em curto período consistiu em mudança no tamanho das UF, com número fixo de UF, conforme revelado por taxas semelhantes de fotossíntese máxima (Fmax), maiores valores de alfa e menores de Ik em baixa irradiância. Os conteúdos de clorofila a seguiram o padrão geral reportado para algas verdes de maiores concentrações em baixa irradiância. Curvas de indução escuro/luz revelaram valores consistentemente mais elevados de rendimento quântico potencial em baixa irradiância. Valores iniciais e finais mostraram capacidade de recuperação mais elevada em curto período (84,4-90,6%) do que em longo período (81,4-81,5%). Os valores da taxa de transporte de elétrons (ETR) e extinção não-fotoquímica (NPQ) foram consistentemente mais elevados em baixa irradiância. Os valores de ETR tiveram aumento contínuo e estável ao longo do período de exposição luminosa em curto e longo períodos, enquanto que os de NPQ revelaram aumento rápido após 15 seconds de exposição à luz, mantiveram leve tendência de aumento e então estabilizaram na maioria dos tratamentos. Performances fotossintéticas inferiores e menor capacidade de recuperação do rendimento quântico potencial foram observadas, sugerindo que esta população sofre inibições pelo típico ambiente de alta irradiância de regiões tropicais.

In long-term exposure, plants acclimated by altering the photosynthetic units (PSU) number and keeping fixed the PSU size, revealed by increased rates of maximum photosynthesis (Pmax), lower photosynthetic efficiency (alpha) and higher values of the saturation parameter (Ik) under high irradiance. The short-term acclimation strategy consisted of changing the PSU size, with a fixed number of PSUs, as revealed by similar Pmax but higher alpha and lower Ik under low irradiance.

Tolerance to cadmium in Chlamydomonas sp. (Chlorophyta) strains isolated from an extreme acidic environment, the Tinto River (SW, Spain)  

International Nuclear Information System (INIS)

[en] The effects of selected concentrations of Cd on the growth and ultrastructure of three strains of Chlamydomonas sp. isolated from a highly acidic river, Rio Tinto (SW Spain) were examined. The river is characterized by its extreme physico-chemical conditions in terms of low pH, mean 2.2 and high concentrations of heavy metals. Growth, Cd accumulation, chlorophyll a, influence of Fe in Cd toxicity and ultrastructural localization were determined. The strains were cultured in both, artificial chemically defined media as well as in natural water from the river. Since iron is the main component of the river water, the effect of different concentrations of this element in relation with Cd toxicity was also analysed. The three strains analysed showed comparable growth and ultrastructural changes. Cd concentration corresponding to 50% growth inhibition (EC5) was 0.2 mM when cells were grown in artificial media. When cells were grown in natural water, no significant differences were found between the controls and the Cd supplemented media even at the highest concentration of 0.8 mM. At an inhibitory level of 0.1 mM of Cd, increasing the concentration of iron up to 90 or 180 mM resulted in a dramatic recovery in algal growth rates in artificial media, reaching normal growth curves. The accumulation of Cd depended on dose and time in the artificial media. The maximal accumulation of Cd was reached after 3 days for all Cd doses, and remained almost unchanged in the subsequent period of time. Chlorophyll a amount depended on dose but not on time in the artificial growth media. At the ultrastructural level, an increase in the periplasmalemmal space was observed due to the presence of a large number of vacuoles, together with a decrease in the relative volume of the nucleus when the cells were incubated in the presence of Cd. Pyrenoid and starch granules were observed and accumulation of spherical electron-dense bodies were also detected. X-ray spectra of these bodies for cells growing in artificial acid media showed intense C, O and Cd signals. In addition to these peaks, a strong Fe signal was also observed when cells were grown in natural acidic water

Positive Perceptions of Access to Online Library Resources Correlates with Quality and Quantity of Scholarly Publications among Finnish Academics. A Review of: Vakkari, Pertti. “Perceived Influence of the Use of Electronic Information Resources on Scholarly Work and Publication Productivity.” Journal of the American Society for Information Science and Technology 59.4 (Feb. 15, 2008): 602-12.  

Directory of Open Access Journals (Sweden)

Full Text Available Objective – To investigate the relationship between academics’ use of library electronic resources and their opinions regarding how these resources have impacted their work, and to investigate the association between this perceived influence and publication productivity during the previous two years.Design – Two specific questions added to an annual online user-survey questionnaire; additional data mined from surveySetting – Twenty-two Finnish Universities served by FinELib, the Finnish Electronic Library.Subjects – Seven hundred and sixty seven academic staff and full-time doctoral students.Methods – A questionnaire was posted in April 2007 on FinELib’s homepage and advertised on each university library’s mainpage, and focused on respondents’ experience in the previous two years. Participants selected answers either from a list of category choices, or, when measuring perceptions, by rating agreement with statements along a four-point scale. Controlled variables measured were the respondents’ academic position, their discipline, membership in a research group, whether their literature use was discipline-specific or interdisciplinary, and their perception of the availability online of the relevant core literature. The independent variable measured was the scholars’ perception of the impact of the use of electronic library resources on their work. The dependent variable measured was the scholars’ self-reported publications in the two years preceding the survey.Main Results – Participants reported a positive impact on the efficiency of their work, most strongly in areas of ease of access, with lesser impacts in the range of materials available to them and the ease with which they can keep up-to-date in their field. To a lesser extent, the scholars perceived a positive impact on the quality of their work. Upon analysis, the study found that access to online library resources improved scholars’ work by the interconnected mechanisms of the ease of access and breadth of resources available positively impacting their ability to keep abreast of new developments and inspiring new ideas. The study found mixed results between perceived improved access and number of publications. Although representation in national publications was not significantly impacted, there was a positive correlation with the number of international publications. There were interesting differences among disciplines and academic status, with a decreased impact among scholars in the humanities, and greater impact among lower-status or novice academics.Conclusion – There are positive perceptions of the accessibility of online information and of its impact on the quality of work, and a correlation between these perceptions and the number of international publications, thus validating the investment in providing access to digital information resources to Finnish academics.

La actividad enzimática de RUBISCO y PEPCK se comportó de una manera similar a los procesos carboxilantes in vivo, indicando que la fotosíntesis y la fijación de carbono en oscuridad son reguladas por la actividad de las enzimas carboxilantes a lo largo del talo de L. setchellii

Water Resources  

International Nuclear Information System (INIS)

Water is essential for life and ecological sustenance; its availability is essential component of national welfare and productivity.The country's socio-economic activities are largely dependent on the natural endowment of water resources. Kenya's water resources comprises of surface waters (rivers, lakes and wetlands) and ground water. Surface water forms 86% of total water resources while the rest is ground water Geological, topographical and climatic factors influence the natural availability and distribution of water with the rainfall distribution having the major influence. Water resources in Kenya are continuously under threat of depletion and quality degradation owing to rising population, industrialization, changing land use and settlement activities as well as natural changes. However, the anticipated climate change is likely to exacerbate the situation resulting in increased conflict over water use rights in particular, and, natural resource utilisation in general. The impacts of climate change on the water resources would lead to other impacts on environmental and socio-economic systems

Resource economics  

Energy Technology Data Exchange (ETDEWEB)

The allocation of scarce resources is becoming crucial to human existence and it is essential to have an understanding of the role of economic factors in this problem. This is the central theme of Resource Economics. The author outlines the key concepts and tools of economics and illustrates their application by reference to problems of renewable resource management, non-renewable resource allocation, pollution and environmental impact analysis. A second theme running throughout the test is the need for economics to integrate with other scientific disciplines if resource allocation problems are to be understood fully and if a framework for their solution is to be found. The emphasis is on graphical means of illustration and everyday examples - rather than on mathematical notation and complex theory - making this a straightforward and immensely readable book.

Rethinking resources  

Energy Technology Data Exchange (ETDEWEB)

With few exceptions, energy and mineral resources have historically been underestimated, chiefly because technology and human ingenuity have been ignored, undervalued, or thought to be irrelevant to finite resources. The changed perceptions of U.S. natural gas resources over the past decade-and-a-half provide an excellent example of the impact of rigorously applied technology. Notably, this impact came during a decade-long period of inordinately low prices, when utility of technology was the only alternative. Natural gas activity was, perhaps for the first time in the extensive U.S. history of exploration and development, a pure technological-ingenuity play. As a result, natural gas supplies, curtailed in the 1970`s, have exceeded demand for a decade. Estimates of remaining gas resources made in the resource-scarce decade of the the 1970`s are now exceeded by at least an order of magnitude. The lesson in natural gas is but a recent reminder of the role of technology and human ingenuity in addressing problems of natural resources and environments. The real limit we have yet to reach is, as Pecora stated in Limitations of the Earth a quarter-century ago, man`s intellectual capacity.

The Biomedical Resource Ontology (BRO) to enable resource discovery in clinical and translational research.  

UK PubMed Central (United Kingdom)

The biomedical research community relies on a diverse set of resources, both within their own institutions and at other research centers. In addition, an increasing number of shared electronic resources have been developed. Without effective means to locate and query these resources, it is challenging, if not impossible, for investigators to be aware of the myriad resources available, or to effectively perform resource discovery when the need arises. In this paper, we describe the development and use of the Biomedical Resource Ontology (BRO) to enable semantic annotation and discovery of biomedical resources. We also describe the Resource Discovery System (RDS) which is a federated, inter-institutional pilot project that uses the BRO to facilitate resource discovery on the Internet. Through the RDS framework and its associated Biositemaps infrastructure, the BRO facilitates semantic search and discovery of biomedical resources, breaking down barriers and streamlining scientific research that will improve human health.

Resource abundance and resource dependence in China  

International Nuclear Information System (INIS)

[en] This paper reconsiders the 'curse of resources' hypothesis for the case of China, and distinguishes between resource abundance, resource rents, and resource dependence. Resource abundance and resource rents are shown to be approximately equivalent, and their association with resource dependence varies with institutional quality. Resource abundance/rents has a positive impact on economic growth, while resource dependence has a negative impact. The impact of the 'West China Development Drive' policy, started in 2000, is substantial, and this is investigated through a comparative analysis based on cross-section samples, and through a panel-data timevarying coefficient approach for West and East provinces. Resource effects do change after the policy shock.

Energy Technology Data Exchange (ETDEWEB)

This section describes the ambient (surrounding) air quality of the TVA region, discusses TVA emission contributions to ambient air quality, and identifies air quality impacts to human health and welfare. Volume 2 Technical Document 2, Environmental Consequences, describes how changes in TVA emissions could affect regional air quality, human health, environmental resources, and materials. The primary region of the affected environment is broadly defined as the state of Tennessee, as well as southern Kentucky, western Virginia, southern West Virginia, western North Carolina, and northern Georgia, Alabama, and Mississippi. This area represents the watershed of the Tennessee River and the 201 counties of the greater TVA service area. Emissions from outside the Tennessee Valley region contribute to air quality in the Valley. Also, TVA emissions are transported outside the Valley and have some impact on air quality beyond the primary study area. Although the study area experiences a number of air quality problems, overall air quality is good.

Mineral resources  

International Nuclear Information System (INIS)

This paper reports that to prevent the concentration of control over federal oil and gas resources in a few companies or individuals, Congress has limited the number of acres of oil and gas leases that one party may control in a single state. An exception to this limitation involves lease acreage within the boundaries of development contracts. These contracts permit oil and gas lease operators and pipeline companies to contract with enough lessees to economically justify large-scale drilling operations for the production and transportation of oil and gas, subject to approval by the Secretary of the Interior, who must find that such contracts are in the public interest. Since 1986 Interior has entered into or approved 10 contracts with 12 lease operators for exploration of largely unleased federal lands-ranging from about 180,000 to 3.5 million acres in four western states-and has designated them as developmental contracts. GAO believes that the 10 contracts do not satisfy the legal requirements for development contracts because they are for oil and gas exploration on largely unleased federal lands, rather than for developing existing leases. By designating the 10 contracts as development contracts, Interior has enabled nine of the 12 contract parties to accumulate lease acreage that vastly exceeds the statutory acreage limitation. All nine of the contract parties were major or large independent oil companies. As a result, other parties who wish to participate in developing federal oil and gas resources within the four states may be adversely affected because the parties to Interior's contracts have been able to compete for and obtain lease acreage beyond the statutory acreage limitation. Although Interior believes that the Secretary has the discretion under law to use development contracts in the current manner, in April 1989 it ceased issuing these contracts pending completion of GAO's review

Photosynthetic carbon metabolism in Enteromorpha compressa (Chlorophyta)  

Energy Technology Data Exchange (ETDEWEB)

The intertidal macroalga Enteromorpha compressa showed the ability to use HCO/sub 3//sup -/, as an exogenous inorganic carbon (Ci) source for photosynthesis. However, although the natural sea water concentration of this carbon form was saturating, additional CO/sub 2/ above ambient Ci levels doubled net photosynthetic rates. Therefore, the productivity of this alga, when submerged, is likely to be limited by Ci. When plants were exposed to air, photosynthetic rates saturated at air-levels of CO/sub 2/ during mild desiccation. Based on carbon fixing enzyme activities and Ci pulse-chase incorporation patterns, it was found that Enteromorpha is a C/sub 3/ plant. However, this alga did not show O/sub 2/ inhibited photosynthetic rates at natural sea water Ci conditions. It is suggested that such a C/sub 4/-like gas exchange response is due to the HCO/sub 3//sup -/ utilization system concentrating CO/sub 2/ intracellularly, thus alleviating apparent photorespiration.

EVOLUTION OF DEVELOPMENTAL PROGRAMS IN VOLVOX (CHLOROPHYTA)  

UK PubMed Central (United Kingdom)

The volvocine green algal genus Volvox includes ~20 species with diverse sizes (in terms of both diameter and cell number), morphologies, and developmental programs. Two suites of characters are shared among distantly related lineages within Volvox. The traits characteristic of all species of Volvox--large (>500) numbers of small somatic cells, much smaller numbers of reproductive cells, and oogamy in sexual reproduction--have three or possibly four separate origins. In addition, some species have evolved a suite of developmental characters that differs from the ancestral developmental program. Most multicellular volvocine algae, including some species of Volvox, share an unusual pattern of cell division known as palintomy or multiple fission. Asexual reproductive cells (gonidia) grow up to many times their initial size and then divide several times in rapid succession, with little or no growth between divisions. Three separate Volvox lineages have evolved a reduced form of palintomy in which reproductive cells are small and grow between cell divisions. In each case, these changes are accompanied by a reduction in the rate of cell division and by a requirement of light for cell division to occur. Thus, two suites of characters--those characteristic of all Volvox species and those related to reduced palintomy--have each evolved convergently or in parallel in lineages that diverged at least 175 million years ago (mya).

The application of dispersed generation, storage, and load control for reduced system costs, (2) Custom power. The application of advanced power electronic equipment for increased reliability for preferred customers. The application of distributed resources may result in lower reliability and power quality for customers on selected feeders because of the lower reliability of generation and storage equipment compared to the reliability of system upgrades. Custom power is a natural complement for distributed resources, providing increased reliability to preferred customers on affected feeders. Custom power technologies include the application of power electronic converters operating at distribution voltages to mitigate disturbances at customer load sites.

In the fields of power conversion devices and broadcasting/communication amplifiers, high power, high frequency and low losses are desirable. Further, for electronic elements in aerospace/aeronautical/geothermal surveys, etc., heat resistance to 500degC is required. Devices which respond to such hard specifications are called hard electronic devices. However, with Si which is at the core of the present electronics, the specifications cannot fully be fulfilled because of the restrictions arising from physical values. Accordingly, taking up new device materials/structures necessary to construct hard electronics, technologies to develop these to a level of IC were examined and studied. They are a technology to make devices/IC of new semiconductors such as SiC, diamond, etc. which can handle higher temperature, higher power and higher frequency than Si and also is possible of reducing losses, a technology to make devices of hard semiconducter materials such as a vacuum microelectronics technology using ultra-micro/high-luminance electronic emitter using negative electron affinity which diamond, etc. have, a technology to make devices of oxides which have various electric properties, etc. 321 refs., 194 figs., 8 tabs.

The Shadow Uniform Resource Locator  

Science.gov (United States)

Citation of scientific materials published on the Internet is often cumbersome because of unwieldy uniform resource locators (URLs). The authors describe a format for URLs that simplifies citation of scholarly materials. Its use depends on a simple HTML device, the “refresh page.” Uniform citation would follow this format: [Author I. Title of article. http://domain/year/month-day(e#).html ]. The HTML code for such a page is: . The code instructs the browser to suppress the content of the refresh page and bring up the title page of the cited article instead. Citations would be succinct and predictable. An electronic journal would not need to alter its existing file hierarchy but would need to establish a distinct domain name and maintain a file of refresh pages. Utilization of the “shadow” URL would bring us one step closer to truly universal resource locators.

Economics of exhaustible resources  

Energy Technology Data Exchange (ETDEWEB)

This dissertation deals with various issues of resource depletion, beginning with a rather comprehensive review of the literature. The resource scarcity is the first issue dealt with, where differentiation is made between Ricardian and Pure scarcities of exhaustible resources. While the Ricardian scarcity is properly acknowledged and modeled in the resource literature, the fact that the resource stocks are always decreasing with extraction (i.e., the pure scarcity) is overlooked. One important conclusion of the scarcity analysis is that the steady-state point defining the equilibrium values for the nonresource output to capital and the resource flow to resource stock ratios, is found to be a moving one, as a result of the increasing scarcity mechanism. Another observation about the literature is that there is a marked bias in favor of long run, developed economies' problems and resource inputs as opposed to the problems of developing economies and resource exports. Thus, a theoretical framework is developed where not only resource inputs and exports are analyzed but resource exports are advanced as a vehicle for development. Within the context of this theoretical framework, it is concluded that optimality dictates that the resource inputs and exports, expressed per unit of the capital stock, be declining over time. Furthermore, the resource exports are proposed as the domestic substitute for foreign aid.

Resource use efficiency  

Energy Technology Data Exchange (ETDEWEB)

In this chapter we concentrate on the efficiency of use in fixing carbon and accumulating biomass of those resources most often of interest to ecophysiologists: light, nutrients, water, and carbon. A plant uses these in a variety of ways to enable it to survive, grow, and reproduce. Resources also have a role in the gathering of other resources. In most natural environments, one or more resources will be in limited supply, at least for a portion of each year or for a part of the plant`s life cycle, or both. This shortage will limit physiological activity and growth. Knowledge of how plants use resources is basic to an understanding of the biology of ecosystems and of competition between species. Efficiency of use of resources has traditionally been determined by calculating ratios of productivity per unit of resource [i.e., resource use efficiencies (RUEs); carbon use is often expressed as relative growth rate (RGR)]. Although RUEs and comparisons of values from different species can often be useful, they are frequently used incautiously. Comparisons have been made at a range of physical and temporal scales, often using the same terminology at each level of scale, frequently incorporating different meanings of productivity or different measures of resource use, sometimes with both different. Species will have evolved a higher RUE in response to a shortage of the resource in their environment. A resource shortage can result from an inherently poor supply of the resource in the environment and from competition for the resource by other plants. Mechanisms that allow plants to grow in an environment that is resource limited can be physiological, anatomical, morphological, ontogenetic, or phenological. RUEs of different resources will evolve separately, presumably in relation to the limitations of the resources in that environment and to other selective pressures.

Oscillator clustering in a resource distribution chain  

Science.gov (United States)

The paper investigates the special clustering phenomena that one can observe in systems of nonlinear oscillators that are coupled via a shared flow of primary resources (or a common power supply). This type of coupling, which appears to be quite frequent in nature, implies that one can no longer separate the inherent dynamics of the individual oscillator from the properties of the coupling network. Illustrated by examples from microbiological population dynamics, renal physiology, and electronic oscillator theory, we show how competition for primary resources in a resource distribution chain leads to a number of new generic phenomena, including partial synchronization, sliding of the synchronization region with the resource supply, and coupling-induced inhomogeneity.

Full Text Available Se aislaron cuatro clones de Pseudoderbesia y se mantuvieron como cultivos unialgales: dos provenientes de la Costa Colombiana del Caribe (P. arbuscula) y dos de las Islas Canarias en el Océano Atlántico (Pseudoderbesia sp.). Aunque se conoce solo la fase gametofítica, hay razones suficientes para el establecimiento de un nuevo género. Se describe y discute el crecimiento, variabilidad, producción bajo condiciones de cultivo. Se sugiere la posibilidad que ciertas especies de Derbesia que poseen ramificación dicotómica y filamentos gradualmente atenuados, como D. fastigiata, D. attenuata y D. padinae, sean realmente miembros de Pseudoderbesia. Pseudoderbesia is described as a new genus within the Bryopsidaceae. Four clones of Pseudoderbesia were isolated and kept as unialgal cultures: two from the Caribbean coast of Colombia (P. arbuscula) and two from the Canary Islands, Atlantic Ocean (Pseudoderbesia sp.). Although only the gametophytic phase is known, it is distinct enough for the establishement of a new genus. Growth, variability and swarmer production, under culture conditions, are described and discussed. It is suggested, that some little known species of Derbesia with dichotomous branching and gradually attenuated filaments, like D. fastigiata, D. attenuata and D. padinae, could actually be members of Pseudoderbesia.

Hospital resource allocation.  

UK PubMed Central (United Kingdom)

Good resource allocation is essential to effective hospital cost management. Yet current allocation methods are weak, and the damage done by bad allocations cannot be undone with utilization fine-tuning. The three traditional methods are resource-allocation-by-momentum (RAM); resource-allocation-by-physician (RAP); and resource-allocation-to-survive (RAS). As hospitals change, a new allocation method is needed: resource-allocation-in-response-to-need (RARN). To determine appropriate allocations, RARN analyzes each activity based upon community need, hospital response, and economics. RARN balances cost management emphasis of doing things right (utilization) with doing the right things (allocation).

Bootstrapping Deep Lexical Resources: Resources for Courses  

CERN Multimedia

We propose a range of deep lexical acquisition methods which make use of morphological, syntactic and ontological language resources to model word similarity and bootstrap from a seed lexicon. The different methods are deployed in learning lexical items for a precision grammar, and shown to each have strengths and weaknesses over different word classes. A particular focus of this paper is the relative accessibility of different language resource types, and predicted ``bang for the buck'' associated with each in deep lexical acquisition applications.

Genetic Resources Action International (GRAIN)  

Science.gov (United States)

Founded in 1990 and based in Spain, Genetic Resources Action International (GRAIN) is an international, non-governmental organization committed to ending the loss of genetic diversity (genetic erosion). GRAIN's mission is based on the premise that "the loss of biological diversity, particularly in the 'gene rich' countries of the Third World, undermines the very sense of sustainable agriculture as it destroys choices for the future and robs people of a key resource base for survival." To that end, the GRAIN homepage (in English, French or Spanish) offers the online quarterly newsletter Seedling, with relevant articles and editorials back to 1995; Books, briefings and other materials; Global Trade and Biodiversity in Conflict (a series of critical reports that examine "points of conflict between the privatization of biodiversity ... and peoples' efforts to empower local communities in biological and cultural diversity management"); and BIO-IPR, a new electronic mailing list from GRAIN. For those interested in global biodiversity issues, this is an interesting and up-to-date resource.

Competition for finite resources  

Science.gov (United States)

The resources in a cell are finite, which implies that the various components of the cell must compete for resources. One such resource is the ribosomes used during translation to create proteins. Motivated by this example, we explore this competition by connecting two totally asymmetric simple exclusion processes (TASEPs) to a finite pool of particles. Expanding on our previous work, we focus on the effects on the density and current of having different entry and exit rates.

Measuring natural resource scarcity  

Energy Technology Data Exchange (ETDEWEB)

Conclusions concerning trends in natural resource scarcity may depend critically on the choice of scarcity index. Unfortunately, the prevalence of vertical integration in natural resource industries has hindered the use of some otherwise desirable scarcity measures. In this paper duality theory is used to derive an econometric procedure for estimating one such measure, the shadow price of the resource in situ. Empirical results for the Canadian metal mining industry indicate that resource scarcity as measured by this shadow price has decreased substantially over time. 23 refernces, 1 table.

2005 resource options report  

International Nuclear Information System (INIS)

This resource options report (ROR) fulfils regulatory requirements in British Columbia's two-year resource planning process. It identifies a wide range of resources and technologies that could be used to meet BC Hydro's future electricity demand. As such, it facilitates a transparent public review of resource options which include both supply-side and demand-side options. The resource options that will be used in the 2005 integrated electricity plan (IEP) were characterized. This ROR also documents where there is a general agreement or disagreement on the resource type characterization, based on the First Nations and Stakeholder engagement. BC Hydro used current information to provide realistic ranges on volume and cost to characterize environmental and social attributes. The BC Hydro system was modelled to assess the benefit and cost of various resource options. The information resulting from this ROR and IEP will help in making decisions on how to structure competitive acquisition calls and to determine the level of transmission services needed to advance certain BC Hydro projects. The IEP forecasts the nature and quantity of domestic resources required over the next 20 years. A strategic direction on how those needs will be met has been created to guide the management of BC Hydro's energy resources. Supply-side options include near-commercial technologies such as energy storage, ocean waves, tidal, fuel cells and integrated coal gasification combined cycle technology. Supply-side options also include natural gas, coal, biomass, geothermal, wind, and hydro. 120 refs., 39 tabs., 21 figs., 6 appendices

Resource Buying Games  

CERN Multimedia

In resource buying games a set of players jointly buys a subset of a finite resource set E (e.g., machines, edges, or nodes in a digraph). The cost of a resource e depends on the number (or load) of players using e, and has to be paid completely by the players before it becomes available. Each player i needs at least one set of a predefined family S_i in 2^E to be available. Thus, resource buying games can be seen as a variant of congestion games in which the load-dependent costs of the resources can be shared arbitrarily among the players. A strategy of player i in resource buying games is a tuple consisting of one of i's desired configurations S_i together with a payment vector p_i in R^E_+ indicating how much i is willing to contribute towards the purchase of the chosen resources. In this paper, we study the existence and computational complexity of pure Nash equilibria (PNE, for short) of resource buying games. In contrast to classical congestion games for which equilibria are guaranteed to exist, the exi...

The Electronic Emissary is "a Web-based telementoring service and resource center" where K-12 teachers and students can locate mentors who are experts in various disciplines in order to assist in "curriculum-based electronic exchanges among the teachers, their students, and the mentors." Interactions take place through electronic mail, web forum, chat, and teleconferencing exchanges and typically range in length from 6 weeks to a full academic year, depending on students' needs and interests. Although classroom teachers serve as the subject matter experts, this practice termed "telementoring" allows additional expertise to be made directly available to students and teachers in cases where "the issues being explored are multi-disciplinary, technically and conceptually sophisticated, or dependent upon current and highly specialized research and theory." Staff of the Electronic Emissary also conduct research by facilitating and investigating "the nature of online communication between adult subject matter expert volunteers and elementary, middle-level, and secondary students and their teachers." The website includes summaries of completed Electronic Emissary learning projects, and additional information on the project and how to get involved either as a mentor, student or teacher. The project is on a volunteer basis and there are no monetary costs associated with it as long as you have Internet access. Some parts of the website were still under construction at the time of this review.

Electron Tree  

DEFF Research Database (Denmark)

The photo shows a close-up of a Lichtenberg figure – popularly called an “electron tree” – produced in a cylinder of polymethyl methacrylate (PMMA). Electron trees are created by irradiating a suitable insulating material, in this case PMMA, with an intense high energy electron beam. Upon discharge, during dielectric breakdown in the material, the electrons generate branching chains of fractures on leaving the PMMA, producing the tree pattern seen. To be able to create electron trees with a clinical linear accelerator, one needs to access the primary electron beam used for photon treatments. We appropriated a linac that was being decommissioned in our department and dismantled the head to circumvent the target and ion chambers. This is one of 24 electron trees produced before we had to stop the fun and allow the rest of the accelerator to be disassembled.

1999 Pacific Northwest Loads and Resources Study.  

Energy Technology Data Exchange (ETDEWEB)

The Pacific Northwest Loads and Resources Study (White Book) is published annually by BPA and establishes the planning basis for supplying electricity to customers. It serves a dual purpose. First, the White Book presents projections of regional and Federal system load and resource capabilities, along with relevant definitions and explanations. Second, the White Book serves as a benchmark for annual BPA determinations made pursuant to its regional power sales contracts. Specifically, BPA uses the information in the White Book for determining the notice required when customers request to increase or decrease the amount of power purchased from BPA. The White Book will not be used in calculations for the 2002 regional power sales contract subscription process. The White Book compiles information obtained from several formalized resource planning reports and data submittals, including those from the Northwest Power Planning Council (Council) and the Pacific Northwest Utilities Conference Committee (PNUCC). The White Book is not an operational planning guide, nor is it used for determining BPA revenues. Operation of the Federal Columbia River Power System (FCRPS) is based on a set of criteria different from that used for resource planning decisions. Operational planning is dependent upon real-time or near-term knowledge of system conditions, including expectations of river flows and runoff, market opportunities, availability of reservoir storage, energy exchanges, and other factors affecting the dynamics of operating a power system. In this loads and resources study, resource availability is compared with a medium forecast of electricity consumption. The forecasted future electricity demands--firm loads--are subtracted from the projected capability of existing and ''contracted for'' resources to determine whether BPA and the region will be surplus or deficit. If Federal system resources are greater than loads in any particular year or month, there is a surplus of energy and/or capacity, which BPA may use or market to increase revenues. Conversely, if Federal system firm loads exceed available resources, there is a deficit of energy and/or capacity and BPA would add conservation or contract purchases as needed to meet its firm loads. The load forecast is derived by using econometric models and analysis to predict the loads that will be placed on electric utilities in the region. This study incorporates information on contract obligations and contract resources, combined with the resource capabilities obtained from public utility and investor-owned utility (IOU) customers through their annual data submittals to the PNUCC, from BPA's Firm Resource Exhibit (FRE Exhibit I) submittals, and through analysis of the Federal hydroelectric power system. The loads and resources analysis in this study simulates the operation of the power system under the Pacific Northwest Coordination Agreement (PNCA) produced by the Pacific Northwest Coordinating Group. The PNCA defines the planning and operation of the regional hydrosystem. The 1999 White Book is presented in two documents: (1) this summary of Federal system and Pacific Northwest region loads and resources; and (2) a technical appendix (available electronically only) detailing the loads and resources for each major Pacific Northwest generating utility. This analysis updates the December 1998 Pacific Northwest Loads and Resources Study. This analysis projects the yearly average energy consumption and resource availability for Operating Years (OY) 2000-01 through 2009-10. The study shows the Federal system's and the region's monthly estimated maximum electricity demand, monthly energy demand, monthly energy generation, and monthly maximum generating capability--capacity--for OY 2000-01, 2004-05, and 2009-10. The Federal system and regional monthly capacity surplus/deficit projections are summarized for 10 operating years. This document analyzes the Pacific Northwest's projected loads and available generating resources in two parts: (1) the loads and

2005 resource options report  

Energy Technology Data Exchange (ETDEWEB)

This resource options report (ROR) fulfils regulatory requirements in British Columbia's two-year resource planning process. It identifies a wide range of resources and technologies that could be used to meet BC Hydro's future electricity demand. As such, it facilitates a transparent public review of resource options which include both supply-side and demand-side options. The resource options that will be used in the 2005 integrated electricity plan (IEP) were characterized. This ROR also documents where there is a general agreement or disagreement on the resource type characterization, based on the First Nations and Stakeholder engagement. BC Hydro used current information to provide realistic ranges on volume and cost to characterize environmental and social attributes. The BC Hydro system was modelled to assess the benefit and cost of various resource options. The information resulting from this ROR and IEP will help in making decisions on how to structure competitive acquisition calls and to determine the level of transmission services needed to advance certain BC Hydro projects. The IEP forecasts the nature and quantity of domestic resources required over the next 20 years. A strategic direction on how those needs will be met has been created to guide the management of BC Hydro's energy resources. Supply-side options include near-commercial technologies such as energy storage, ocean waves, tidal, fuel cells and integrated coal gasification combined cycle technology. Supply-side options also include natural gas, coal, biomass, geothermal, wind, and hydro. 120 refs., 39 tabs., 21 figs., 6 appendices.

Microfluidic electronics.  

UK PubMed Central (United Kingdom)

Microfluidics, a field that has been well-established for several decades, has seen extensive applications in the areas of biology, chemistry, and medicine. However, it might be very hard to imagine how such soft microfluidic devices would be used in other areas, such as electronics, in which stiff, solid metals, insulators, and semiconductors have previously dominated. Very recently, things have radically changed. Taking advantage of native properties of microfluidics, advances in microfluidics-based electronics have shown great potential in numerous new appealing applications, e.g. bio-inspired devices, body-worn healthcare and medical sensing systems, and ergonomic units, in which conventional rigid, bulky electronics are facing insurmountable obstacles to fulfil the demand on comfortable user experience. Not only would the birth of microfluidic electronics contribute to both the microfluidics and electronics fields, but it may also shape the future of our daily life. Nevertheless, microfluidic electronics are still at a very early stage, and significant efforts in research and development are needed to advance this emerging field. The intention of this article is to review recent research outcomes in the field of microfluidic electronics, and address current technical challenges and issues. The outlook of future development in microfluidic electronic devices and systems, as well as new fabrication techniques, is also discussed. Moreover, the authors would like to inspire both the microfluidics and electronics communities to further exploit this newly-established field.

Uranium resource assessments  

International Nuclear Information System (INIS)

The objective of this investigation is to examine what is generally known about uranium resources, what is subject to conjecture, how well do the explorers themselves understand the occurrence of uranium, and who are the various participants in the exploration process. From this we hope to reach a better understanding of the quality of uranium resource estimates as well as the nature of the exploration process. The underlying questions will remain unanswered. But given an inability to estimate precisely our uranium resources, how much do we really need to know. To answer this latter question, the various Department of Energy needs for uranium resource estimates are examined. This allows consideration of whether or not given the absence of more complete long-term supply data and the associated problems of uranium deliverability for the electric utility industry, we are now threatened with nuclear power plants eventually standing idle due to an unanticipated lack of fuel for their reactors. Obviously this is of some consequence to the government and energy consuming public. The report is organized into four parts. Section I evaluates the uranium resource data base and the various methodologies of resource assessment. Part II describes the manner in which a private company goes about exploring for uranium and the nature of its internal need for resource information. Part III examines the structure of the industry for the purpose of determining the character of the industry with respect to resource development. Part IV arrives at conclusions about the emerging pattern of industrial behavior with respect to uranium supply and the implications this has for coping with national energy issues

NATURAL RESOURCES ASSESSMENT  

Energy Technology Data Exchange (ETDEWEB)

The purpose of this report is to summarize the scientific work that was performed to evaluate and assess the occurrence and economic potential of natural resources within the geologic setting of the Yucca Mountain area. The extent of the regional areas of investigation for each commodity differs and those areas are described in more detail in the major subsections of this report. Natural resource assessments have focused on an area defined as the ''conceptual controlled area'' because of the requirements contained in the U.S. Nuclear Regulatory Commission Regulation, 10 CFR Part 60, to define long-term boundaries for potential radionuclide releases. New requirements (proposed 10 CFR Part 63 [Dyer 1999]) have obviated the need for defining such an area. However, for the purposes of this report, the area being discussed, in most cases, is the previously defined ''conceptual controlled area'', now renamed the ''natural resources site study area'' for this report (shown on Figure 1). Resource potential can be difficult to assess because it is dependent upon many factors, including economics (demand, supply, cost), the potential discovery of new uses for resources, or the potential discovery of synthetics to replace natural resource use. The evaluations summarized are based on present-day use and economic potential of the resources. The objective of this report is to summarize the existing reports and information for the Yucca Mountain area on: (1) Metallic mineral and mined energy resources (such as gold, silver, etc., including uranium); (2) Industrial rocks and minerals (such as sand, gravel, building stone, etc.); (3) Hydrocarbons (including oil, natural gas, tar sands, oil shales, and coal); and (4) Geothermal resources. Groundwater is present at the Yucca Mountain site at depths ranging from 500 to 750 m (about 1,600 to 2,500 ft) below the ground surface. Groundwater resources are not discussed in this report, but are planned to be included in the hydrology section of future revisions of the ''Yucca Mountain Site Description'' (CRWMS M&O 2000c).

Information technology resources assessment  

Energy Technology Data Exchange (ETDEWEB)

The emphasis in Information Technology (IT) development has shifted from technology management to information management, and the tools of information management are increasingly at the disposal of end-users, people who deal with information. Moreover, the interactive capabilities of technologies such as hypertext, scientific visualization, virtual reality, video conferencing, and even database management systems have placed in the hands of users a significant amount of discretion over how these resources will be used. The emergence of high-performance networks, as well as network operating systems, improved interoperability, and platform independence of applications will eliminate technical barriers to the use of data, increase the power and range of resources that can be used cooperatively, and open up a wealth of possibilities for new applications. The very scope of these prospects for the immediate future is a problem for the IT planner or administrator. Technology procurement and implementation, integration of new technologies into the existing infrastructure, cost recovery and usage of networks and networked resources, training issues, and security concerns such as data protection and access to experiments are just some of the issues that need to be considered in the emerging IT environment. As managers we must use technology to improve competitiveness. When procuring new systems, we must take advantage of scalable resources. New resources such as distributed file systems can improve access to and efficiency of existing operating systems. In addition, we must assess opportunities to improve information worker productivity and information management through tedmologies such as distributed computational visualization and teleseminar applications.

Resource revenues report  

International Nuclear Information System (INIS)

[en] Preliminary forecasts of resource revenues that may be forthcoming with the lifting of the moratorium on the west coast of British Columbia were presented. The forecasts are based on the development scenarios of one natural gas project in the Hecate Strait, and one oil project in the Queen Charlotte Sound. Both projects were assessed in an effort to demonstrate some of the potential resource revenues and public benefits that may be possible from offshore development in the province. Resource revenues provide the return-on-investments to the resource developer and public benefits in the form of taxes, royalties, lease payments and related fees to all levels of governments. Much of the revenues generated from the British Columbia offshore oil and gas development will accrue as income taxes. A public energy trust offers a way to transform non-renewable resource revenues into a renewable source of wealth for citizens of the province. The report presents estimates of project investment, pipeline capacity limitation, operating costs for offshore platforms, and earnings. It was estimated that about $2.0 billion in public benefits would be generated from combined project revenues of $6.9 billion. Information was obtained from offshore leaseholders as well as pipeline and engineering companies. refs., tabs., figs

Mineral resources of Serbia  

Energy Technology Data Exchange (ETDEWEB)

The mineral resources of Serbia were formed by complex processes of metallogenic development and in various geological epochs (Pre-Baikalian to Alpine). Their overview in this paper is supported by the simplified Metallogenic map of Serbia showing virtually selected mineral deposits, as well as by maps of the most important fossil fuel resources. The most important group of metallic mineral resources of Serbia includes Cu, Pb-Zn, Au, Ag, Sn, Mn, U, Mo, Ti, W, Co, Sb and Fe ores. The important group of industrial mineral resources include: bentonite, boron minerals, refractory clay, gypsum and anhydrite, diatomite, dolomite, zeolite, kaoline, quartz sand, cement marl, ceramic clay, limestone, magnesite, phosphates, chrysotile-asbestos, building industry granulates (natural and crushed) and decorative stone. Serbia also has significant resources of fossil fuels, particularly coal and oil shale. The soft brown coal (lignite) is of great economic importance since it represents the main source for the production of electric energy. The remaining petroleum potential of the Pannonian Basin in Serbia indicates that modern exploration may result in the discovery of significant additional reserves of oil and gas. Production of shale-oil also has great potential, but it depends on future detailed valorization of various factors.

Electronic Cigarette  

UK PubMed Central (United Kingdom)

An electronic cigarette has two tubes that resemble a cigarette: an electronic inhaler and an electronic atomizer. The two tubes are connected through one or more electric connectors to form an electronic cigarette. Inside the inhaler is a rechargeable or non-rechargeable power source such as a battery, which supplies electric power to the electronic inhaler and atomizer and ensures that both work together like a cigarette. In addition to the power source, the inhaler also includes other major components: an electric airflow sensor to detect air movement generated by a user's inhaling or puffing act and a Single Chip Micyoco which controls the atomization process. The sensor's role is to collect an airflow signal that triggers the Single Chip Micyoco, which in turn instructs the electronic cigarette to supply electric power to the inhaler and atomizer connected through an electric connector. Inside the electronic atomizer are an electric connector, electric heating wire, liquid container, and atomizer cap with an air-puffing hole. The user inhales through the air-puffing hole at an end of the electronic cigarette to create an air inflow, which triggers the atomization process. The Single Chip Micyoco driven by a software program controls the electronic cigarette in an on/off manner according to the signal detected by the electric sensor on the airflow and completes a cycle of atomization, which converts a solution of a liquid form inside the liquid container to a gas form. This entire process achieves the emulated smoking process of a user, who is satisfied with scent taste that mimics cigarette smoking.

Electronic ballasts  

Energy Technology Data Exchange (ETDEWEB)

Fluorescent lamps are the most common choice in many industrial and commercial lighting applications. All fluorescent lighting systems require ballasts. The standard core and coil type ballasts consume typically about 10% to 20% of the total input energy. The new line of ballasts available in the market known as electronic ballasts offer substantial cost savings because of reduced electrical consumption. This article explores the theory behind the electronic ballasts. A case study is presented to illustrate economical justification of replacing the existing core and coil ballasts with electronic ballasts in conjunction with the replacement of conventional F40T12 lamps with FO32T8 lamps.

Nanobiotechnology Human Resource Development  

Directory of Open Access Journals (Sweden)

Full Text Available Human resource development is very important component of any development activity of national and international importance. A careful planning and implementation besides mid course corrections and feedbacks are essential for success in this area. In spite of very rapid progress made in several fields of late the human resource crunch is being faced today very seriously. How to overcome the difficulties being faced in preparing ourselves to generate appropriate type of human resources is the subject discussed here with special reference to the typical requirements of Nanobiotechnology. Multidisciplinary and multiinstitutional approach is the key to success as discussed in the present paper. The proposed guidelines are equally valid for any modern discipline emerging in future and therefore the total plan should be prepared by taking into account all the components appropriately and then implementing monitoring and midcourse corrections based on the feedbacks.

Resource conservation management  

Energy Technology Data Exchange (ETDEWEB)

Resource conservation management is a management program similar to financial management in that its success requires commitment by all levels of the organization to the process as well as an accounting procedure and auditing of critical components. Resource conservation management provides a framework for all elements of efficient building operations and maintenance. The savings connected with the program are principally connected with changes in the way buildings are operated and maintained. Given the reduction in rebates for the installation of energy-efficient equipment, this approach has considerable promise. This paper discusses the evolution of the resource conservation management service and the savings associated with a two-year pilot effort with seven school districts, as well as the critical components of a successful program.

Storage resource manager  

Energy Technology Data Exchange (ETDEWEB)

Storage Resource Managers (SRMs) are middleware components whose function is to provide dynamic space allocation and file management on shared storage components on the Grid[1,2]. SRMs support protocol negotiation and reliable replication mechanism. The SRM standard supports independent SRM implementations, allowing for a uniform access to heterogeneous storage elements. SRMs allow site-specific policies at each location. Resource Reservations made through SRMs have limited lifetimes and allow for automatic collection of unused resources thus preventing clogging of storage systems with ''orphan'' files. At Fermilab, data handling systems use the SRM management interface to the dCache Distributed Disk Cache [5,6] and the Enstore Tape Storage System [15] as key components to satisfy current and future user requests [4]. The SAM project offers the SRM interface for its internal caches as well.

2004 Pacific Northwest Loads and Resources Study.  

Energy Technology Data Exchange (ETDEWEB)

The Pacific Northwest Loads and Resources Study (White Book), which is published annually by the Bonneville Power Administration (BPA), establishes one of the planning bases for supplying electricity to customers. The White Book contains projections of regional and Federal system load and resource capabilities, along with relevant definitions and explanations. The White Book also contains information obtained from formalized resource planning reports and data submittals including those from individual utilities, the Northwest Power and Conservation Council (Council), and the Pacific Northwest Utilities Conference Committee (PNUCC). The White Book is not an operational planning guide, nor is it used for determining BPA revenues, although the database that generates the data for the White Book analysis contributes to the development of BPA's inventory and ratemaking processes. Operation of the Federal Columbia River Power System (FCRPS) is based on a set of criteria different from that used for resource planning decisions. Operational planning is dependent upon real-time or near-term knowledge of system conditions that include expectations of river flows and runoff, market opportunities, availability of reservoir storage, energy exchanges, and other factors affecting the dynamics of operating a power system. The load resource balance of BPA and/or the region is determined by comparing resource availability to an expected level of total retail electricity consumption. Resources include projected energy capability plus contract purchases. Loads include a forecast of retail obligations plus contract obligations. Surplus energy is available when resources are greater than loads. This energy could be marketed to increase revenues. Energy deficits occur when resources are less than loads. These deficits could be met by any combination of the following: better-than-critical water conditions, demand-side management and conservation programs, permanent loss of loads due to economic conditions or closures, additional contract purchases, and/or the addition of new generating resources. The loads and resources analysis in this study simulates the operation of the power system under the current Pacific Northwest Coordination Agreement (PNCA). The PNCA defines the planning and operation of seventeen U.S. Pacific Northwest utilities and other parties with generating facilities within the region's hydroelectric (hydro) system. The hydroregulation study used for the 2004 White Book incorporates measures from the National Oceanographic and Atmospheric Administration Fisheries (NOAA Fisheries) Biological Opinion dated December 2000, and the U.S. Fish and Wildlife Service's 2000 Biological Opinion (2000 FCRPS BiOps) for the Snake River and Columbia River projects. These measures include: (1) Increased flow augmentation for juvenile fish migrations in the Snake and Columbia rivers in the spring and summer; (2) Mandatory spill requirements at the Lower Snake and Columbia dams to provide for non-turbine passage routes for juvenile fish migrants; and (3) Additional flows for Kootenai River white sturgeon in the spring; The hydroregulation criteria for this analysis includes the following: (1) Detailed Operation Plan operation for Treaty reservoirs for Operating Year (OY) 2004; (2) PNCA planning criteria for OY 2004; and (3) Juvenile fish bypass spill levels for 2000 FCRPS BiOps implementation. The 2004 White Book is presented in two documents: (1) this summary document of Federal system and PNW region loads and resources, and (2) a technical appendix which presents regional loads, grouped by major PNW utility categories, and detailed contract and resource information. The technical appendix is available only in electronic form. Individual customer information for marketer contracts is not detailed due to confidentiality agreements. The 2004 White Book analysis updates the 2003 White Book. This analysis projects the yearly average energy consumption and resource availability for the study period, OY 2006 through 2015.

Food and energy resources  

Energy Technology Data Exchange (ETDEWEB)

The rapidly expanding human population needs more nutritious food. Our ability to produce more food depends on sufficient arable land, water, and various forms of energy. Supplies of these basic agricultural resources are under pressure from the human population, because, as it grows, more land is required for forests, houses, and roads, as well as for agriculture. At the same time, demands on energy supplies increase for various activities that include production of food crops. To some extent, energy in the form of fertilizers or irrigation water can be substituted for more land, or land can be substituted for energy inputs in crop production. These trade-offs are complex and illustrate not only the close interrelationships among the various factors but also the interdependencies of these relationships. Contributors try here to put in perspective the influence that energy, land, and water resources have a food production. Clearly, future supplies of energy resources will have a major impact on the ability of humans to provide themselves with food. A better understanding of these issues will help society make sound choices and enable government leaders to develop and organize the necessary programs for the effective use of energy and food resources.

Canadian gas resource  

International Nuclear Information System (INIS)

Canadian exports of gas to the United States are a critical component of EMF-9 (North American Gas Supplies). However, it has been noted that there are differences between US expectations for imports and Canadian forecasts of export supply capacity. Recent studies by the National Petroleum Council (NPC) and the US Department of Energy (DOE) indicate that 1.8 to 2.4 Tcf of imports may be required in the mid to late 1990's; A recent study by Canada's National Energy Board (NEB) indicates that the conventional resource base may not be able to provide continued gas exports to the US after the mid 1990's and that frontier sources would need to be developed to meet US expectations. The discrepancies between US expectations and Canadian estimates of capacity are of great concern to US policymakers because they call into question the availability of secure supplies of natural gas and suggest that the cost of imports (if available) will be high. By implication, if shortages are to be averted, massive investment may be required to bring these higher cost sources to market. Since the long-term supply picture will be determined by the underlying resource base, EMF-9 participants have been asked to provide estimates of critical components of the Canadian resource base. This paper provides a summary of ICF-Lewin's recent investigation of both the Conventional and Tight Gas resource in Canada's Western Sedimentary Basin, which includes both quantitative estimates and a brief sketch of the analysis methodology.

Utilitarian resource assignment  

CERN Document Server

This paper studies a resource allocation problem introduced by Koutsoupias and Papadimitriou. The scenario is modelled as a multiple-player game in which each player selects one of a finite number of known resources. The cost to the player is the total weight of all players who choose that resource, multiplied by the ``delay'' of that resource. Recent papers have studied the Nash equilibria and social optima of this game in terms of the $L_\\infty$ cost metric, in which the social cost is taken to be the maximum cost to any player. We study the $L_1$ variant of this game, in which the social cost is taken to be the sum of the costs to the individual players, rather than the maximum of these costs. We give bounds on the size of the coordination ratio, which is the ratio between the social cost incurred by selfish behavior and the optimal social cost; we also study the algorithmic problem of finding optimal (lowest-cost) assignments and Nash Equilibria. Additionally, we obtain bounds on the ratio between alterna...

Full Text Available We consider that the human being is the most important asset of the company. In the context of the socialpolitics of the company and of the objectives of the man agement, along with all the other departments, the managementcontrol contributes to the resources of the entity. In this paper we want to demonstrate the importance of human capitalas one of the key factors of the growth process in all countries and the necessity of the organization of a managementcontrol to be able to provide information about human resources. Which are the axes for the reporting of theinformation concerning the human resources? What kind of reports and indicators should be prepared by companiesfor management? Which are the main concerns of the companies connected to profitableness – efficiency – wages? Theanswer will be found in this paper. In the current conditions in which personnel restructuring processes, combined withthe costs reduction efforts and new requirements arise in the management control of the company, our paper willpresent how we can make a correct assessment of the value created by the human resources component of the company

HUMAN RESOURCE MANAGEMENT & TECHNOLOGICAL CRISIS  

Directory of Open Access Journals (Sweden)

Full Text Available One would tend to think that Human Resource management in one country would be much like it is in another country. There are similarities in the human resource function from one country to another however; due to cultural differences the human resource function can also be quite different. We must first define the Field of Human Resource Management. According to Peter Dowling in International Human Resource Management, “Human resource management is those activities undertaken by an organization to utilize its human resources effectively.” These activities include but are not limited to, human resource planning, staffing, performance management, training and education, compensation and benefits, and labor relations.“People are your most valuable asset”Human resource professionals must stay informed and be involved in the employee and workplace development process with quality training to ensure legal compliance, performance management, and the implementation of effective personnel policies.

Uranium resources and supply  

International Nuclear Information System (INIS)

[en] Over the next decades the supply of uranium will be a vital factor in the fulfilment of the world's nuclear power programmes. Forecasts of nuclear power installation, which have only been marginally modified in the last two years, indicate spectacular increases over the next decades. The consequent demand for uranium will also increase proportionally during this period and the uranium producing industry is faced with considerable problems in discovering and developing sufficient resources to meet long term demand and in finding adequate production capacity in the short term. The IAEA together with the Nuclear Energy Agency of OECD has been concerned with the problems of uranium supply and demand for a number of years and has produced, at roughly two-year intervals, a series of reports on these subjects so as to provide the Governments of Member States and the uranium and nuclear power industry with the best available information on these subjects. The latest report in this series, compiled by the joint NEA/IAEA Working Party and entitled 'Uranium Resources, Production and Demand' was published by NEA(OECD) in December 1975. The report's main findings are summarised in the following paragraphs: The question of adequacy of world uranium resources compared to world uranium demand has received increased attention in the past two years. The fossil fuel price increase has resulted in research into new forms of energy and has confirmed that apart from coal, uranium is likely to be the only energy source available in sufficient quantity to meet the increasing energy demand in the foreseeable future. While it appears that the known uranium resources are adequate to support the planned and projected nuclear reactor programmes for the next ten to fifteen years, severe supply problems may arise in the longer term. It is therefore necessary to monitor continuously the development in nuclear power growth forecasts and to set them into relation to the known uranium resources and the production they can support. This report, like its forerunners, attempts to present a most recent overall picture in this respect. Its emphasis, as in previous reports, lies on the uranium resources side, being in its larger part compiled by a working party of uranium resources experts. However it also covers, in lesser detail, the rest of the nuclear fuel cycle and future uranium demand. (author)

Valuation of ecological resources  

Energy Technology Data Exchange (ETDEWEB)

Ecological resources are resources that have functional value to ecosystems. Frequently, these functions are overlooked in terms of the value they provide to humans. Environmental economics is in search of an appropriate analysis framework for such resources. In such a framework, it is essential to distinguish between two related subsets of information: (1) ecological processes that have intrinsic value to natural ecosystems; and (2) ecological functions that are values by humans. The present study addresses these concerns by identifying a habitat that is being displaced by development, and by measuring the human and ecological values associated with the ecological resources in that habitat. It is also essential to determine which functions are mutually exclusive and which are, in effect, complementary or products of joint production. The authors apply several resource valuation tools, including contingent valuation methodology (CVM), travel cost methodology (TCM), and hedonic damage-pricing (HDP). One way to derive upper-limit values for more difficult-to-value functions is through the use of human analogs, because human-engineered systems are relatively inefficient at supplying the desired services when compared with natural systems. Where data on the relative efficiencies of natural systems and human analogs exist, it is possible to adjust the costs of providing the human analog by the relative efficiency of the natural system to obtain a more realistic value of the function under consideration. The authors demonstrate this approach in an environmental economic case study of the environmental services rendered by shrub-steppe habitats of Benton County, Washington State.

Geothermal resources of Montana  

Energy Technology Data Exchange (ETDEWEB)

The Montana Bureau of Mines and Geology has updated its inventory of low and moderate temperature resources for the state and has assisted the Oregon Institute of Technology - GeoHeat Center and the University of Utah Research Institute in prioritizing and collocating important geothermal resource areas. The database compiled for this assessment contains information on location, flow, water chemistry, and estimated reservoir temperatures for 267 geothermal well and springs in Montana. For this assessment, the minimum temperature for low-temperature resource is defined as 10{degree} C above the mean annual air temperature at the surface. The maximum temperature for a moderate-temperature resource is defined as greater than 50{degree} C. Approximately 12% of the wells and springs in the database have temperatures above 50{degree} C, 17% are between 30{degree} and 50{degree} C, 29% are between 20{degree} and 30{degree}C, and 42% are between 10{degree} and 20{degree} C. Low and moderate temperature wells and springs can be found in nearly all areas of Montana, but most are in the western third of the state. Information sources for the current database include the MBMG Ground Water Information Center, the USGS statewide database, the USGS GEOTHERM database, and new information collected as part of this program. Five areas of Montana were identified for consideration in future investigations of geothermal development. The areas identified are those near Bozeman, Ennis, Butte, Boulder, and Camas Prairie. These areas were chosen based on the potential of the resource and its proximity to population centers.

2003 Pacific Northwest Loads and Resources Study.  

Energy Technology Data Exchange (ETDEWEB)

The Pacific Northwest Loads and Resources Study (White Book), which is published annually by the Bonneville Power Administration (BPA), establishes one of the planning bases for supplying electricity to customers. The White Book contains projections of regional and Federal system load and resource capabilities, along with relevant definitions and explanations. The White Book also contains information obtained from formalized resource planning reports and data submittals including those from individual utilities, the Northwest Power and Conservation Council (Council), and the Pacific Northwest Utilities Conference Committee (PNUCC). The White Book is not an operational planning guide, nor is it used for determining BPA revenues, although the database that generates the data for the White Book analysis contributes to the development of BPA's inventory and ratemaking processes. Operation of the Federal Columbia River Power System (FCRPS) is based on a set of criteria different from that used for resource planning decisions. Operational planning is dependent upon real-time or near-term knowledge of system conditions that include expectations of river flows and runoff, market opportunities, availability of reservoir storage, energy exchanges, and other factors affecting the dynamics of operating a power system. In this loads and resources study, resource availability is compared to an expected level of total retail electricity consumption. The forecasted annual energy electricity retail load plus contract obligations are subtracted from the sum of the projected annual energy capability of existing resources and contract purchases to determine whether BPA and/or the region will be surplus or deficit. Surplus energy is available when resources are greater than loads. This energy could be marketed to increase revenues. Deficits occur when resources are less than loads. Energy deficits could be met by any combination of the following: better-than-critical water conditions, demand-side management and conservation programs, permanent loss of a load (i.e., due to economic conditions or closures), additional contract purchases, and/or new generating resources. The loads and resources analysis in this study simulates the operation of the power system under the Pacific Northwest Coordination Agreement (PNCA). The PNCA defines the planning and operation of seventeen U.S. Pacific Northwest utilities and other parties with generating facilities within the region's hydroelectric (hydro) system. The hydroregulation study used for the 2003 White Book incorporates measures from the National Oceanographic and Atmospheric Administration Fisheries (NOAA Fisheries) Biological Opinion dated December 2000, and the U.S. Fish and Wildlife Service's 2000 Biological Opinion (2000 FCRPS BiOps) for the Snake River and Columbia River projects. These measures include: (1) Increased flow augmentation for juvenile fish migrations in the Snake and Columbia rivers in the spring and summer; (2) Mandatory spill requirements at the Lower Snake and Columbia dams to provide for non-turbine passage routes for juvenile fish migrants; and (3) Additional flows for Kootenai River white sturgeon in the spring. The hydroregulation criteria for this analysis includes: an updated Detailed Operation Plan for Treaty reservoirs for Operating Year (OY) 2004, updated PNCA planning criteria for OY 2003, and revised juvenile fish bypass spill levels for 2000 FCRPS BiOps implementation. The 2003 White Book is presented in two documents: (1) this summary document of Federal system and PNW region loads and resources, and (2) a technical appendix which presents regional loads, grouped by major PNW utility categories, and detailed contract and resource information. The technical appendix is available only in electronic form. Individual customer information regarding marketer contracts is not detailed due to confidentiality agreements. The 2003 White Book analysis updates the December 2002 White Book. This analysis projects the yearly average energy consumption and resour

Resource Overbooking: Using Aggregation Profiling in large scale Resource Discovery  

Directory of Open Access Journals (Sweden)

Full Text Available Resource discovery is an important process for finding suitable nodes that satisfy application requirements in large loosely coupled distributed systems. Besides inter node heterogeneity, many of these systems also show a high degree of intra node dynamism, so that selecting nodes based only on their recently observed resource capacities can lead to poor deployment decisions resulting in application failures or migration overheads. However, most existing resource discovery mechanisms rely mainly on recent observations to achieve scalability in large systems. In this paper, we propose the notion of a resource bundle—a representative resource usage distribution for a group of nodes with similar resource usage patterns—that employs two complementary techniques to overcome the limitations of existing techniques: resource usage histograms to provide statistical guarantees for resource capacities and clustering-based resource aggregation to achieve scalability. Using trace-driven simulations and data analysis of a month-long Planet Lab trace, we show that resource bundles are able to provide high accuracy for statistical resource discovery, while achieving high scalability. We also show that resource bundles are ideally suited for identifying group-level characteristics (e.g., hot spots, total group capacity)

Within this paper we present an autonomic Computing resources management system used by LHCb for assessing the status of their Grid resources. Virtual Organizations Grids include heterogeneous resources. For example, LHC experiments very often use resources not provided by WLCG and Cloud Computing resources will soon provide a non-negligible fraction of their computing power. The lack of standards and procedures across experiments and sites generated the appearance of multiple information systems, monitoring tools, ticket portals, etc... which nowadays coexist and represent a very precious source of information for running HEP experiments Computing systems as well as sites. These two facts lead to many particular solutions for a general problem: managing the experiment resources. In this paper we present how LHCb, via the DIRAC interware addressed such issues.

Coal resources of Alaska  

Energy Technology Data Exchange (ETDEWEB)

In the late 1800s, whaling ships carried Alaskan coal, and it was used to thaw ground for placer gold mining. Unfortunate and costly political maneuvers in the early 1900s delayed coal removal, but the Alaska Railroad and then World War II provided incentives for opening mines. Today, 33 million acres (about 9% of the state) is classified as prospectively valuable for coal, much of it under federal title. Although the state's geology is poorly known, potential for discovery of new fields exists. The US Geological Survey estimates are outdated, although still officially used. The total Alaska onshore coal resource is estimated to be 216 to 4216 billion tons of which 141 billion tons are identified resources; an additional 1430 billion tons are believed to lie beneath Cook Inlet. Transportation over mountain ranges and wetlands is the biggest hurdle for removal. Known coal sources and types are described and mapped. 1 figure.

Taxation of mineral resources  

Energy Technology Data Exchange (ETDEWEB)

There has been a substantial increase in recent years in the level of taxation imposed on mining firms by state and local governments. This increase can be attributed to three factors: (1) a heightened awareness that resources are limited in quantity; (2) environmental damage resulting from mining operations has brought demands for just compensations; and (3) significant price increases for some minerals have often been viewed by states as an opportunity to collect additional tax revenue. The broad aim of this book is to provide a comprehensive economic analysis of the effects of mining taxation on the extraction of mineral resources and to offer a set of recommendations for tax policy. The primary objective of this design is to minimize the distortionary incentives created by the taxation. From a practical standpoint, however, one must also recognize the degrees of difficulty in the administration of the various taxes. 90 references, 1 figure, 14 tables.

Lignocellulosic feedstock resource assessment  

Energy Technology Data Exchange (ETDEWEB)

In 1997, the National Renewable Energy Laboratory (NREL) undertook a national biomass resource assessment to address a lack of basic resource information for scientists, industry, and policy-makers. The objective of this resource assessment was to describe the state-level distribution, quantity and market value of lignocellulosic feedstocks for ethanol production in the United States. Lignocellulosic feedstocks, derived from plant materials, are composed primarily of cellulose, hemicellulose, and lignin. Cellulose and hemicellulose are polymers of simple sugars that can be chemically fermented to produce ethanol. Lignin plays a role in binding cellulose and hemicellulose together in plant cell walls. This study focused on lignocellulosic by-products of agriculture, food processing, forest products industry, and consumers. The United States generates 306 million metric tons (dry weight) of lignocellulosic materials annually that could be used to manufacture ethanol. The bulk of this potential feedstock supply is made up of agricultural residues left following crop harvesting, such as corn stover. Corn stover makes up 70 percent of the total biomass resource. If agricultural residues are used for ethanol production, the price paid for agricultural residues will have to meet or exceed their current soil nutrient and animal fodder values. Food processing residues such as corn gluten feed and meal, distillers' dried grains, and spent brewer's grains are used as animal feed additives, which makes them high in cost in relation to other feedstocks. Forest products residues are mostly used for fuel, pulp, animal bedding, or mulch. The unutilized portion of these residues may be available for ethanol production. Recycled paper, sugarcane bagasse, rice straw, paper sludge, and urban tree residue show potential for use as ethanol feedstocks due to their low cost. (author)

Ensembl variation resources.  

UK PubMed Central (United Kingdom)

BACKGROUND: The maturing field of genomics is rapidly increasing the number of sequenced genomes and producing more information from those previously sequenced. Much of this additional information is variation data derived from sampling multiple individuals of a given species with the goal of discovering new variants and characterising the population frequencies of the variants that are already known. These data have immense value for many studies, including those designed to understand evolution and connect genotype to phenotype. Maximising the utility of the data requires that it be stored in an accessible manner that facilitates the integration of variation data with other genome resources such as gene annotation and comparative genomics. DESCRIPTION: The Ensembl project provides comprehensive and integrated variation resources for a wide variety of chordate genomes. This paper provides a detailed description of the sources of data and the methods for creating the Ensembl variation databases. It also explores the utility of the information by explaining the range of query options available, from using interactive web displays, to online data mining tools and connecting directly to the data servers programmatically. It gives a good overview of the variation resources and future plans for expanding the variation data within Ensembl. CONCLUSIONS: Variation data is an important key to understanding the functional and phenotypic differences between individuals. The development of new sequencing and genotyping technologies is greatly increasing the amount of variation data known for almost all genomes. The Ensembl variation resources are integrated into the Ensembl genome browser and provide a comprehensive way to access this data in the context of a widely used genome bioinformatics system. All Ensembl data is freely available at http://www.ensembl.org and from the public MySQL database server at ensembldb.ensembl.org.

Yukon energy resources: Alternatives  

Energy Technology Data Exchange (ETDEWEB)

Alternative energy resources other than cord wood have remained largely undeveloped to date despite the fact that the Yukon depends greatly on imported petroleum products for heating oil, transportation fuel and diesel for electric power generation. Photovoltaics are considered to be the most competitive renewable energy source for remote, off-grid sites. Proponents of the technology claim that they have reliable energy eight months of the year. Geothermal energy is the most practical to develop in geologically active zones such as the `Pacific Ring of Fire` which is a region that encircles the Pacific Ocean and includes the Yukon. The basic features of developable geothermal reservoirs were presented. Municipal solid waste and used oil are two sources of refuse-derived energy that have been studied for possible application in the Yukon. No comprehensive study has been conducted on the Yukon`s peat resources because of the remoteness of the peat bogs. There are substantial coal resources but more study is needed to determine if coal bed methane is of high enough quality to be used as an energy source. The current state of development, specific characteristics of each alternative energy source and associated economic, environmental and regulatory aspects were briefly described. 1 tab., 9 figs.

Information technology resources assessment  

Energy Technology Data Exchange (ETDEWEB)

This year`s Information Technology Resources Assessment (ITRA) is something of a departure from traditional practice. Past assessments have concentrated on developments in fundamental technology, particularly with respect to hardware. They form an impressive chronicle of decreasing cycle times, increasing densities, decreasing costs (or, equivalently, increasing capacity and capability per dollar spent), and new system architectures, with a leavening of operating systems and languages. Past assessments have aimed -- and succeeded -- at putting information technology squarely in the spotlight; by contrast, in the first part of this assessment, we would like to move it to the background, and encourage the reader to reflect less on the continuing technological miracles of miniaturization in space and time and more on the second- and third-order implications of some possible workplace applications of these miracles. This Information Technology Resources Assessment is intended to provide a sense of technological direction for planners in projecting the hardware, software, and human resources necessary to support the diverse IT requirements of the various components of the DOE community. It is also intended to provide a sense of our new understanding of the place of IT in our organizations.

Harsh environments electronics : downhole applications.  

Energy Technology Data Exchange (ETDEWEB)

The development and operational sustainment of renewable (geothermal) and non-renewable (fossil fuel) energy resources will be accompanied by increasingly higher costs factors: exploration and site preparation, operational maintenance and repair. Increased government oversight in the wake of the Gulf oil spill will only add to the cost burden. It is important to understand that downhole conditions are not just about elevated temperatures. It is often construed that military electronics are exposed to the upper limit in terms of extreme service environments. Probably the harshest of all service conditions for electronics and electrical equipment are those in oil, gas, and geothermal wells. From the technology perspective, advanced materials, sensors, and microelectronics devices are benefificial to the exploration and sustainment of energy resources, especially in terms of lower costs. Besides the need for the science that creates these breakthroughs - there is also a need for sustained engineering development and testing. Downhole oil, gas, and geothermal well applications can have a wide range of environments and reliability requirements: Temperature, Pressure, Vibration, Corrosion, and Service duration. All too frequently, these conditions are not well-defifined because the application is labeled as 'high temperature'. This ambiguity is problematic when the investigation turns to new approaches for electronic packaging solutions. The objective is to develop harsh environment, electronic packaging that meets customer requirements of cost, performance, and reliability. There are a number of challenges: (1) Materials sets - solder alloys, substrate materials; (2) Manufacturing process - low to middle volumes, low defect counts, new equipment technologies; and (3) Reliability testing - requirements documents, test methods and modeling, relevant standards documents. The cost to develop and sustain renewable and non-renewable energy resources will continue to escalate within the industry. Downhole electronics can provide a very cost-effective approach for well exploration and sustainment (data logging). However, the harsh environments are a 'game-changer' in terms defining materials, assembly processes and the long-term reliability of downhole electronic systems. The system-level approach will enable the integration of each of these contributors - materials, processes, and reliability - in order to deliver cost-effective electronics that meet customer requirements.

Knowledge Resources and Competitive Advantage  

Directory of Open Access Journals (Sweden)

Full Text Available The paper discusses some definitions of knowledge as a potential sourceof competitive advantage. It reviews the literature pertaining to the assessmentof knowledge assets. According to the resource-based view,which links the competitive advantage of organizations with resourcesand capabilities that are firm-specific, and difficult to imitate or substitute,a firm’s competitive advantage is built on a set of strategicallyrelevant resources (Barney 1991; Grant 1991; Peteraf 1993). When firmshave access to similar resources, it is those companies that are able tomaximize the utilization of those resources that attain a competitiveadvantage. Among various strategic resources and capabilities that helpdetermine the extent of competitive advantages, a pivotal role is oftenassigned to knowledge – as both a resource in itself and an integratingfactor that makes other resources and capabilities effective – especiallyin complex and dynamic environments.

Modeling renewable energy resources in integrated resource planning  

Energy Technology Data Exchange (ETDEWEB)

Including renewable energy resources in integrated resource planning (IRP) requires that utility planning models properly consider the relevant attributes of the different renewable resources in addition to conventional supply-side and demand-side options. Otherwise, a utility`s resource plan is unlikely to have an appropriate balance of the various resource options. The current trend toward regulatory set-asides for renewable resources is motivated in part by the perception that the capabilities of current utility planning models are inadequate with regard to renewable resources. Adequate modeling capabilities and utility planning practices are a necessary prerequisite to the long-term penetration of renewable resources into the electric utility industry`s resource mix. This report presents a review of utility planning models conducted for the National Renewable Energy Laboratory (NREL). The review examines the capabilities of utility planning models to address key issues in the choice between renewable resources and other options. The purpose of this review is to provide a basis for identifying high priority areas for advancing the state of the art.

Application of radiation to agro-resources  

International Nuclear Information System (INIS)

A huge amount of agricultural resources such as cellulose and starch is discarded or under-utilized. The upgrading of these wastes into useful end products should be considered in order to recycle agro-resources and to reduce pollution. Radiation treatment is utilized for the sterilization of medical products and the preservation of foods. The objectives of the irradiation on biological materials are the disinfection of micro-organisms and the improvement of the physico-chemical properties. The radiation processing on the fermentation of cellulose waste, sewage sludge, starch and the recovery of protein from the waste water of a potato starch factory or a slaughter house has been studied. In this report, the conversion of oil palm waste into animal feed by gamma irradiation and the composting of sewage sludge by lectron beam irradiation are described. The determination of the molecular size of enzymes in situ by radiation inactivation method is also described as the basic study of electron beam irradiation on biological materials. Electron beam is practically useful for the treatment of large amounts of oil palm waste and sewage sludge. (K.I.).

OBJECTIVES: The research sought to determine if first-year medical students consulted and cited resources specifically highlighted during library instructional sessions. METHODS: Students attended a library resources instructional session. Resources that pertained to the students' assignment were demonstrated and discussed. The students created a report including citations from relevant literature. The citations were analyzed and categorized as: a resource discussed at the instructional session, a resource found on the course LibGuide, a library resource, course material, or some other resource. All citations were subcategorized as print or electronic. RESULTS: Three years (2008-2011) of data analyzing 2,983 citations showed that 49.55% of all citations were from resources discussed during library instructional sessions; 21.86% came from resources with links on the course LibGuide; 77.51% were from library resources; and 90.68% came from electronic resources. CONCLUSION: Students cited resources specifically highlighted during library instructional sessions for their assignments. The percentage of all citations coming from resources highlighted during the instructional sessions or found on the course LibGuide indicates that library instruction had an impact on the students' work.

Resource programs: Draft Environmental Impact Statement Resource Programs  

International Nuclear Information System (INIS)

Every two years, Bonneville Power Administration (BPA) prepares a Resource Program which identifies the resource actions BPA will take to meet its obligation to serve the forecasted power requirements of its customers. The Resource Program's Environmental Impact Statement (RPEIS) is a programmatic environmental document which will support decisions made in several future Resource Programs. Environmental documents tiered to the EIS may be prepared on a site-specific basis. The RPEIS includes a description of the environmental effects and mitigation for the various resource types available in order to evaluate the trade-offs among them. It also assesses the environmental impacts of adding thirteen alternative combinations of resources to the existing power system. This report contains the appendices to the RPEIS

Linear electron-electron colliders  

Energy Technology Data Exchange (ETDEWEB)

In the framework of the discussion on what shape the future machine arsenal should take so as to maximize the chances of penetrating beyond the realm where the present astonishingly successful Standard Model of Particle Interactions holds undisputed sway, the present contribution is somewhat unusual: the author is not here to convince the community to build yet another machine. Instead, his task is to convince you that in the established choices that the accelerator community is headed towards, it is of great importance that the Electron Collider of the next generation, i.e., in the 0.5 to 1.5 TeV energy range, should be configured just such, as an Electron collider, NOT dedicated to just one incoming charge state (say, e{sup +}e{sup {minus}}). Now that the energy range that can be reached with circular/recirculating machines has been exceeded, designers are freed from the need to have oppositely charged electrons as projectiles and targets. The colliding linac configuration sets no preferential condition on the chosen net charge; in fact, this is the first time such a machine may well serve to collide a variety of initial states at full energy 2E{sub B} and luminosity (e{sup +}e{sup +}, e{sup +}e{sup {minus}}, e{sup {minus}}e{sup {minus}}), or at slightly reduced center-of-mass energy, but still full luminosity ({gamma}-e, {gamma}-{gamma}).

Internet resources for diabetes  

Directory of Open Access Journals (Sweden)

Full Text Available Internet is transforming lives of many people in the world. Nowadays Internet has become one of the most common media to extract information of interest to researchers. The Internet is composed of a large number of smaller interconnected networks called Intranets. These Intranets connect thousands computers enabling them to share information with each other and to share various resources such as powerful super computers, software and databases of information. It has made it possible for people all over the world to effectively and inexpensively communicate with each other. The Internet has become world?s biggest library where retrieval of scientific resources is only a mouse click away. The geometric growth in Internet usage is mainly due to the great success of "World Wide Web". Various useful databases on diabetes are already on ?the Net? and many more being added regularly. The present article is an attempt to provide a review of several sites that may be of great significance to the diabetes researchers before execution for new assignment/project.

Sharing resources@CERN  

CERN Document Server

The library is launching a 'sharing resources@CERN' campaign, aiming to increase the library's utility by including the thousands of books bought by individual groups at CERN. This will improve sharing of information among CERN staff and users. Until now many people were unaware that copies of the same book (or standard, or journal) are often held not only by the library but by different divisions. (Here Eduardo Aldaz, from the PS division, and Isabel Bejar, from the ST division, read their divisional copies of the same book.) The idea behind the library's new sharing resources@CERN' initiative is not at all to collect the books in individual collections at the CERN library, but simply to register them in the Library database. Those not belonging to the library will in principle be unavailable for loan, but should be able to be consulted by anybody at CERN who is interested. "When you need a book urgently and it is not available in the library,' said PS Division engineer Eduardo Aldaz Carroll, it is a sham...

Resources available in society  

Energy Technology Data Exchange (ETDEWEB)

A decontamination operation will only be successful if cost-efficient methods are used. The cost-effectiveness depends, among many other factors, including the qualifications and training of the personnel and the capability of the equipment. The personnel must be able to handle the equipment in a professional way and should also know how to protect themselves. To fulfil these requirements they need courses in radiation protection. The equipment must be suitable for the selected countermeasure. Societies planning and preparedness for reclamation should meet realistic demands for early actions and outline a cost-effective strategy that implies reasonable use of personnel and equipment resources. Planning for early cleanup actions is different from that of long term planning with respect to the available time and quantity and quality of available information on which to base decisions. Available resources vary, of course, between the Nordic countries, but in all countries there are organisations with both knowledgeable staff and suitable equipment accessible for decontamination operations.

Geothermal resources in Algeria  

Energy Technology Data Exchange (ETDEWEB)

The geothermal resources in Algeria are of low-enthalpy type. Most of these geothermal resources are located in the northeastern of the country. There are more than 240 thermal springs in Algeria. Three geothermal zones have been delineated according to some geological and thermal considerations: (1) The Tlemcenian dolomites in the northwestern part of Algeria, (2) carbonate formations in the northeastern part of Algeria and (3) the sandstone Albian reservoir in the Sahara (south of Algeria). The northeastern part of Algeria is geothermally very interesting. Two conceptual geothermal models are presented, concerning the northern and southern part of Algeria. Application of gas geothermometry to northeastern Algerian gases suggests that the reservoir temperature is around 198 C. The quartz geothermometer when applied to thermal springs gave reservoir temperature estimates of about 120 C. The thermal waters are currently used in balneology and in a few experimental direct uses (greenhouses and space heating). The total heat discharge from the main springs and existing wells is approximately 642 MW. The total installed capacity from producing wells and thermal springs is around 900 MW. (author)

Human resources report  

Energy Technology Data Exchange (ETDEWEB)

The human resources issues associated with offshore oil and gas exploration and development in British Columbia were discussed with particular focus on the nature of direct employment opportunities associated with two development scenarios. The scenarios involved one natural gas project in the Hecate Strait, and one oil project in the Queen Charlotte Sound. One of the promises of offshore oil and gas development in British Columbia's west coast has been the creation of employment opportunities which would in turn, improve the social conditions and standard of living of residents in British Columbia. Some background information was provided on labour requirements by phases of exploration, pre-development planning, construction and production. Information on labour supply and training was also included and a range of human resource planning issues were identified. It was concluded that the oil and gas industry is capital-intensive, requiring highly trained and skilled people. The industry supports above average wage rates. Most of the employment is not generated by the oil and gas industry, but by their many service and supply contractors. The existing oil and gas industry in the province could supply some of the qualified labour, but in most instances, more specific training will be required. Exploration activity will probably be intermittent and carried out by specialized work crews. Local employment will come from servicing and supplying the seismic and support vessels. The occupational requirements will change through the exploration, development and production phases. refs., tabs., figs.

Location constrained resource interconnection  

International Nuclear Information System (INIS)

This presentation discussed issues related to wind integration from the perspective of the California Independent System Operator (ISO). Issues related to transmission, reliability, and forecasting were reviewed. Renewable energy sources currently used by the ISO were listed, and details of a new transmission financing plan designed to address the location constraints of renewable energy sources and provide for new transmission infrastructure was presented. The financing mechanism will be financed by participating transmission owners through revenue requirements. New transmission interconnections will include network facilities and generator tie-lines. Tariff revisions have also been implemented to recover the costs of new facilities and generators. The new transmission project will permit wholesale transmission access to areas where there are significant energy resources that are not transportable. A rate impact cap of 15 per cent will be imposed on transmission owners to mitigate short-term costs to ratepayers. The presentation also outlined energy resource area designation plans, renewable energy forecasts, and new wind technologies. Ramping issues were also discussed. It was concluded that the ISO expects to ensure that 20 per cent of its energy will be derived from renewable energy sources. tabs., figs.

The Quality Resources  

Directory of Open Access Journals (Sweden)

Full Text Available A significant element characterizing a lasting development in Braila Plain region, but also in any other similar area, would be anenvironment factor that is the water, with an increasing importance when considered against the high dryness background. Generally speaking, boththe consumed water and the consumption structure reflect the quality and quantity of water resources and, implicitly, the economic potential of theregion at issue. As for Braila Plain, here there is a paradox to be considered: even if the region is bordered by highly significant rivers (The Danubeand Siret) with huge flows – not to mention here the salty water lakes or underground streams with a more or less drinking water – the need ofdrinking water becomes obvious, mostly in summer and autumn. The climate, morphometric and lithological conditions confer certain peculiaritiesupon the waters resources of the Northern-Eastern Romanian Plain. One can say about the Braila Plain hydrographical network that it is poor and thisis due to the discharge, situated under the value of 1 l/sqkm, but also to the very low relief energy. The allochthonous Rivers: the Danube, Siret,Buzau and Calmatui are affected by the relief climate conditions and also by the size and the geographic position of the hydrographical basins.

UWC geothermal resource exploration  

Energy Technology Data Exchange (ETDEWEB)

A program was developed to explore the strength of the geothermal and hot dry rock (HDR) resource at the Montezuma Hot Springs at the United World College (UWC). The purpose of the UWC {number_sign}1 well is to obtain hydrologic, geologic, and temperature information for ongoing geothermal evaluation of the Montezuma Hot Springs area. If sufficient fluids are encountered, the hole will be cased with a 4 1/2 inch production casing and re-permitted as a geothermal low-temperature well. If no fluid is encountered, the well will be abandoned per Oil Conservation Division regulation. The objectives of the exploration are to evaluate the resource potential to provide space heating for the entire campus of the United World College, determine the effect of a well on the Hot Springs outflow, accurately measure the UWC heating loads versus time, evaluate the potential to support local thermal industry development, assess the feasibility of HDR development, and create an educational program from the collection of data derived from the research effort.

Energy and other resources  

International Nuclear Information System (INIS)

It is pointed out that inorganic mineral raw materials, usually called ores, do not form a separate geological class, with a strictly defined limit in quantity. The raw materials are in fact present in continuously variable concentrations and amounts with differing geographical distribution. It is only the richest occurrences which are regarded as resources and exploited. The cone concept of available material is presented, where the amount of material available increases as the work invested is increased, but the profitable ore is represented only by the apex of the cone. In applying this idea to fossil fuels the concept must be modified to a 'pear', since the energy invested in retrieving the fuel must not exceed the energy content of the fuel. Renewable energy sources are also discussed, and it is pointed out that geothermal energy should not be regarded as renewable. It is pointed out, too, that, unless breeder reactors are introduced, the fossil fuel resources will give more energy than uranium, and probably cheaper. (JIW)?.

Grid Resource Allocation: A Review  

Directory of Open Access Journals (Sweden)

Full Text Available As computing technology improves the accessibility to computing resources increases, the demands put on resources gets higher and higher. A grid is a large-scale, heterogeneous, dynamic collection of independent systems, geographically distributed and interconnected with high speed networks. Furthermore, in grid, the resource allocation is a process of allocating user jobs to the CPUs. These jobs are divided into tasks which are allocated to different computers on grid for execution process. Resource allocation is one of the critical features of grid technology. Thus, we found that resource heterogeneity has a great impact on resource allocation which is quite significant in terms of performance, reliability, robustness and scalability. Indeed, the system robustness increases as the system complexity increases. In other words, resource allocation is also an NP complete problem where there is no final solution. The main objective of this study is to review the various grid resource allocations strategies which will in turn serve as a guide for researchers and our vision for future research directions. Therefore, to facilitate further developments in the area, it is essential to survey and review the existing body of knowledge. Therefore, in this chapter, we have studied and classified various ways to achieve an optimum solution. Operation research management (game theory and transportation method) which have been widely use in grid resource allocation for optimum solution, we will design and evaluate a new algorithm for resource allocation either by using simulation or real grid environment.

1990 Resource Program : Technical Report.  

Energy Technology Data Exchange (ETDEWEB)

This Technical Report is a detailed presentation of the actions Bonneville Power Administration (BPA) will take to develop new resources to meet the power requirements of its customers. The primary focus of this report is on what BPA will do in Fiscal Years (FY's) 1992 and 1993. However, much care has been taken to define near-term actions aimed at meeting BPA's long-term needs. An aggressive, steadily increasing conservation program forms the foundation of the 1990 Resource Program and resource acquisitions for FY's 1992 and 1993. BPA's commitment to a steady ramp-up of the conservation program is key to achieving the least-cost approach to resource development, and to making the conservation resource deliverable in the long run. By itself, conservation can meet much of the likely range of load growth that BPA faces. A diverse mix of generation resources in small increments is the second cornerstone of the 1990 Resource Program. These generation resources can meet the rest of the likely range of BPA resource needs. Finally, a Resource Contingency Plan prepares BPA to reliably meet load in the event that load growth exceeds the likely range. 14 figs., 27 tabs.

Uranium resources of Niger  

International Nuclear Information System (INIS)

[en] Full text: After the discovery of the first uranium shows in Niger in 1958 by the BRGM (Bureau de Recherche Geologique et Miniere) at AZELIK, the French CEA (Commissariat a l'Energie Atomique) has carried out a systematic and detailed exploration program from 1959 to 1980 throughout the Tim Mersoi basin (140 000 km2), leading to the discovery of many other uranium shows and deposits among witch, fifteen are worldwide scale. Two other Paleozoic basins (Djado and Emi Lulu) have also a good uranium potential. In 1971, SOMAIR (Societe des Mines de l'Air) began uranium production, followed in 1978 by the COMINAK (Compagnie Miniere d'Akouta), they have produced 110 000 tU. During the first uranium boom (1973-1980) several mining and oil companies (Cogema, Conoco, Pan Ocean, BP, Esso, OURD, IRSA, and PNC) have obtained licenses for Uranium research in Niger. Many uranium shows have been identified, explored and evaluated. The deposits of economic interest are: Arlette, Ariege, Taza, Tamou, Takriza, Artoi, Tabelle, Imouraren, Irhawenzegirhan, Azelik, Madaouela, Ebene, Akouta, Akola, Ebba. Following a spectacular increase of uranium price and demand, the research that has been interrupted for more than a decade have resumed from 2002: 127 exploration permits have been granted to some fifty mining companies in Niger. All economic mineralizations are located in detritic sedimentary formations (conglomerates, sandstone, and siltstones) rich in organic vegetable matters and sulphides, of Carboniferous to Cretaceous ages. In addition to the sedimentological and stratigraphic control, the redox phenomena and tectonic evolution of the northern Niger region played an important role in the occurrence of various deposits. In the Tim Mersoi Basin uranium is essentially found in its proper mineralogical forms, out of which the main identified are primary minerals of pitchblende - uraninite group and coffinite. Its occurrences in the crystalline network of clay minerals and other products are rarely observed. Meanwhile, at Imouraren and Azelik the secondary minerals (gummites, uranotile, tyuyamunite autunite) predominate. The average grade of the economic deposits varies from 0.08% U and 0.6% U. The depths range from 0 to 265 m. Despite the 110 000 tU extracted during the past 40 years, considerable global resources evaluated approximately at 500 000 tU still remain in Niger, shared out as follows: 300 000 tU of reasonably assured and economically recoverable resources, 200 000 tU of estimated additional resources. The speculative resources could double. The exploitation of Imouraren uranium deposit (230 000 tU recoverable) and Azelik (13 700 tU) is in process. Near the Arlit lineament and its satellite faults, detailed exploration work using new methods with more efficiency would give rise to the discovery of other deposits around many existing uranium shows in the following licenses: Madaouela, Adrar Imola, Afasto, Toulouk, Terzemazour, Tagait, Abelajouad, Asamaka, Agelal, Zelin, Tin Negourane, Teguida, Irhazer and In Gall. Niger is about to become the second worldwide uranium producer both in term of production and resources and could, at the current production rate, maintain its ranking for several decades. (author)

Daylighting simulation: methods, algorithms, and resources  

Energy Technology Data Exchange (ETDEWEB)

This document presents work conducted as part of Subtask C, ''Daylighting Design Tools'', Subgroup C2, ''New Daylight Algorithms'', of the IEA SHC Task 21 and the ECBCS Program Annex 29 ''Daylight in Buildings''. The search for and collection of daylighting analysis methods and algorithms led to two important observations. First, there is a wide range of needs for different types of methods to produce a complete analysis tool. These include: Geometry; Light modeling; Characterization of the natural illumination resource; Materials and components properties, representations; and Usability issues (interfaces, interoperability, representation of analysis results, etc). Second, very advantageously, there have been rapid advances in many basic methods in these areas, due to other forces. They are in part driven by: The commercial computer graphics community (commerce, entertainment); The lighting industry; Architectural rendering and visualization for projects; and Academia: Course materials, research. This has led to a very rich set of information resources that have direct applicability to the small daylighting analysis community. Furthermore, much of this information is in fact available online. Because much of the information about methods and algorithms is now online, an innovative reporting strategy was used: the core formats are electronic, and used to produce a printed form only secondarily. The electronic forms include both online WWW pages and a downloadable .PDF file with the same appearance and content. Both electronic forms include live primary and indirect links to actual information sources on the WWW. In most cases, little additional commentary is provided regarding the information links or citations that are provided. This in turn allows the report to be very concise. The links are expected speak for themselves. The report consists of only about 10+ pages, with about 100+ primary links, but with potentially thousands of indirect links. For purposes of the printed version, a list of the links is explicitly provided. This document exists in HTML form at the URL address: http://eande.lbl.gov/Task21/dlalgorithms.html. An equivalent downloadable PDF version, also with live links, at the URL address: http://eande.lbl.gov/Task21/dlalgorithms.pdf. A printed report can be derived directly from either of the electronic versions by simply printing either of them. In addition to the live links in the electronic forms, all report forms, electronic and paper, also have explicitly listed link addresses so that they can be followed up or referenced manually.

Resonant electron effects on trapped electron instabilities

The necessity of distinguishing between perpendicular and parallel components in electron velocity space, rather than simply considering energy, is pointed out and employed to estimate the effects of finite collisionality. For much of the banana regime the dominant resonant electron contributions are shown to be due to circulating electrons with parallel velocities in the vicinity of and slightly below the electron thermal speed

Electronic tomogram  

Energy Technology Data Exchange (ETDEWEB)

There are many proposals on how to improve image processing in conventional longitudinal tomography. One of these is the method of 'ectomography' by which blurring of pictures can be avoided. The method is based on the so-called synthetic tomographic techniques in which projection pictures are stored, e.g. during rotation of an X-ray tube, and tomograms are made from superimposed pictures. If local frequencies are filtered before superposition, better tomograms are obtained. With this technique, principal problems can be investigated for a longer period of time, and the projection pictures can be stored as digital TV pictures. Digital image processing is possible withhout any loss of quality, and filtering of local frequencies is thus possible also in electronic tomograms. The image quality is high, due to the high-resolution X-ray television system used. Also other digital image processing techniques can be used, e.g. computed angiography for intravenous imaging of arteries. The new methods of tomography eliminates one basic problem of intravenous imaging of arteries, namely superposition of vessels. The new electronic method of tomography is well suited for image processing techniques of this type.

Resource heterogeneity can facilitate cooperation.  

UK PubMed Central (United Kingdom)

Although social structure is known to promote cooperation, by locally exposing selfish agents to their own deeds, studies to date assumed that all agents have access to the same level of resources. This is clearly unrealistic. Here we find that cooperation can be maintained when some agents have access to more resources than others. Cooperation can then emerge even in populations in which the temptation to defect is so strong that players would act fully selfishly if their resources were distributed uniformly. Resource heterogeneity can thus be crucial for the emergence and maintenance of cooperation. We also show that resource heterogeneity can hinder cooperation once the temptation to defect is significantly lowered. In all cases, the level of cooperation can be maximized by managing resource heterogeneity.

Issues in Multiagent Resource Allocation  

Directory of Open Access Journals (Sweden)

Full Text Available The allocation of resources within a system of autonomous agents, that not only have preferences over alternative allocations of resources but also actively participate in computing an allocation, is an exciting area of research at the interface of Computer Science and Economics. This paper is a survey of some of the most salient issues in Multiagent Resource Allocation. In particular, we review various languages to represent the preferences of agents over alternative allocations of resources as well as different measures of social welfare to assess the overall quality of an allocation. We also discuss pertinent issues regarding allocation procedures and present important complexity results. Our presentation of theoretical issues is complemented by a discussion of software packages for the simulation of agent-based market places. We also introduce four major application areas for Multiagent Resource Allocation, namely industrial procurement, sharing of satellite resources, manufacturing control, and grid computing.

Biomass energy resource enhancement  

International Nuclear Information System (INIS)

The demand for energy in developing countries is expected to increase to at least three times its present level within the next 25 years. If this demand is to be met by fossil fuels, an additional 2 billion tonnes of crude oil or 3 billion tonnes of coal would be needed every year. This consumption pattern, if allowed to proceed, would add 10 billion tonnes of CO2, to the global atmosphere each year, with its attendant risk of global warming. Therefore, just for our survival, it is imperative to progressively replace fossil fuels by biomass energy resources and to enhance the efficiency of use of the latter. Biomass is not only environmentally benign but is also abundant. It is being photosynthesised at the rate of 200 billion tonnes of carbon every year, which is equivalent to 10 times the world's present demand for energy. Presently, biomass energy resources are highly under-utilised in developing countries; when they are used it is through combustion, which is inefficient and causes widespread environmental pollution with its associated health hazards. Owing to the low bulk density and high moisture content of biomass, which make it difficult to collect, transport and store, as well as its ash-related thermochemical properties, its biodegradability and seasonal availability, the industrial use of biomass is limited to small and (some) medium-scale industries, most of which are unable to afford efficient but often costly energy conversion systems. Considering these constraints and the need to enhance the use base, biomass energy technologies appropriate to developing countries have been identified. Technologies such as briquetting and densification to upgrade biomass fuels are being adopted as conventional measures in some developing countries. The biomass energy base can be enhanced only once these technologies have been shown to be viable under local conditions and with local raw materials, after which they will multiply on their own, as has been the case with briquetting technology in India. To set up the first units, private industries from both developed and developing countries will have to play a dominant role, with assistance from international funding organizations and their respective Governments. Manufacturing activities should gradually be transferred to developing countries, under licensing agreements, because plants installed by developed countries tend to be more expensive and economically unviable. This approach has been successfully practiced for other technologies and will be addressed in this paper. Used sustainably, biomass resource can help to meet the growing demand for energy. (author)

ANALYSIS OF HUMAN RESOURCES MANAGEMENT  

Directory of Open Access Journals (Sweden)

Full Text Available Along with other material, financial resources, human resource is an indispensable element of each work process. The concept of human resource derives exactly from the fact that it has a limited nature and it is consumed by usage in the workplace. Any work process cannot be developed without the labour factor. Work is essentially a conscious activity specific to humans through which they release certain labour objects and transforms them according to his needs.

The combinatorics of resource sharing  

CERN Multimedia

We discuss general models of resource-sharing computations, with emphasis on the combinatorial structures and concepts that underlie the various deadlock models that have been proposed, the design of algorithms and deadlock-handling policies, and concurrency issues. These structures are mostly graph-theoretic in nature, or partially ordered sets for the establishment of priorities among processes and acquisition orders on resources. We also discuss graph-coloring concepts as they relate to resource sharing.

Australian Biological Resources Study  

Science.gov (United States)

Deceptively simple but rich in scope, the mission of the Australian Biological Resources Study (ABRS) is to document which plants and animals are found in Australia, map their locations, and provide information this information to the general public. Part of their mission is fulfilled quite nicely by the presence of this website, which includes material on their research activities and administration, and most importantly a series of online databases. The first of these databases is ABRS Fauna Online. Using this database, known as Platypus, visitors can learn all about the fauna found on the continent, and even download the database package for taxonomists. Of course, visitors would be remiss not to take a look at the like-minded database of Australian flora, which includes similar material. For taxonomists, biologists, and others who are harboring a secret love of such fields, this website is truly a treat.

California Air Resources Board  

Energy Technology Data Exchange (ETDEWEB)

The proposed budget for the next fiscal year, includes an $11.4 million increase for the Air Resources Board (ARB), primarily for new clean air programs mandated by the Legislature and recently signed into law. Those efforts include expanding the Smog Check program to conduct roadside testing of diesel-powered big rig trucks, continuing acid rain research, and administering the California Clean Air Act which accelerates the state's anti-smog program. The increase brings the ARB budget to $75.9 million, a 17.8 percent increase from the $64.5 million spent on clean air programs last year. The larger funding boost, $5.3 million, is for the California Clean Air Act, Which requires the ARB to develop new programs and accelerate existing efforts to meet health-based air quality standards.

California air resources board  

Energy Technology Data Exchange (ETDEWEB)

The Air Resources Board approved measures to reduce highly-toxic, cancer-causing hexavalent chromium emissions from chrome plating shops by at least 97 percent over the next four years, as its February meeting. The action could prevent an estimated 210 to 2600 cancer cases over the next 70 years. More than 400 chrome plating ships statewide which currently emit chromium into the air are affected by the rules, including those in the San Francisco Bay area, San Diego, Sacramento, Southern California and 13 other metropolitan areas. The cost of complying with the rule is expected to range from $25-$2200 a year for decorative platers. Low volume industrial platers are expected to pay to to $9000 for antipollution equipment and up to $2400 in annual upkeep. Similar costs for medium and large platers are estimated at $50,000 and $450,000 for control equipment, respectively, and annual maintenance costs of $11,000 and $94,000.

Analyzing nonrenewable resource supply  

Energy Technology Data Exchange (ETDEWEB)

Starting with their vision of a useful model of supply behavior as dynamic and market oriented, the authors examine the literature to see what it offers, to fill in some of the missing elements, and to direct attention to the research that is required. Following an introduction, separate chapters deal with the basic theory of supply behavior; joint products, externalities, and technical change; uncertainty, expectations, and supply behavior; aggregate supply and market behavior; and empirical methods and problems. The authors argue that practical understanding of nonrenewable resource supply is hampered by gaps among theory, methodology, and data, and offer a standard designed to achieve consistency among theory, data, and estimation methods. Their recommendations for additional research focus on general specification issues, uncertainty and expectations, market-level analysis, and strategic behavioral issues. 151 references, 9 figures.

Resource materials for faculty development.  

UK PubMed Central (United Kingdom)

BACKGROUND AND METHODS: Practical, well-designed, state-of-the-art resources are needed to help medical faculty enhance their skills as educators, researchers, administrators, and academics. Books, audio and video programs, CD-ROM-based programs, and interactive programs created for use on the Internet are needed for independent study, for peer learning, and for activities that are facilitated by faculty developers. The more pressure there is on faculty time, the more desirable becomes the availability of resources that can be used privately, flexibly, and in multiple locations (including home). In this paper, we 1) describe the strategies we used in identifying resources, 2) briefly describe some recently developed resources, 3) make observations about existing resources, and (4) make recommendations for the kinds of resources that need to be created and some criteria to consider when selecting and creating resources. The task of finding existing resources proved to be quite difficult, so as an outgrowth of the research done for this article, we created a Web site (http:@www.uchsc.edu/CIS) that provides a continually updated, annotated list of resources for faculty in the health professions and links to other sites with relevant information.

Resource Allocation using Virtual Clusters  

CERN Multimedia

In this report we demonstrate the potential utility of resource allocation management systems that use virtual machine technology for sharing parallel computing resources among competing jobs. We formalize the resource allocation problem with a number of underlying assumptions, determine its complexity, propose several heuristic algorithms to find near-optimal solutions, and evaluate these algorithms in simulation. We find that among our algorithms one is very efficient and also leads to the best resource allocations. We then describe how our approach can be made more general by removing several of the underlying assumptions.

Waste Electrical and Electronic Equipment  

DEFF Research Database (Denmark)

Waste electrical and electronic equipment (WEEE) is one of the fastest growing special waste types with an estimated growth of 3–5% per year (Cui and Forssberg, 2003). WEEE is a very heterogeneous waste type that contains many compounds that are considered to be harmful to both humans and the environment, as well as many metals that have the potential of being recycled and reused. This makes the waste fraction (WEEE) very interesting as it is a problematic waste as well as an important secondary resource.

Epidermal electronics.  

UK PubMed Central (United Kingdom)

We report classes of electronic systems that achieve thicknesses, effective elastic moduli, bending stiffnesses, and areal mass densities matched to the epidermis. Unlike traditional wafer-based technologies, laminating such devices onto the skin leads to conformal contact and adequate adhesion based on van der Waals interactions alone, in a manner that is mechanically invisible to the user. We describe systems incorporating electrophysiological, temperature, and strain sensors, as well as transistors, light-emitting diodes, photodetectors, radio frequency inductors, capacitors, oscillators, and rectifying diodes. Solar cells and wireless coils provide options for power supply. We used this type of technology to measure electrical activity produced by the heart, brain, and skeletal muscles and show that the resulting data contain sufficient information for an unusual type of computer game controller.

Electronic databases  

Energy Technology Data Exchange (ETDEWEB)

Electronic databases corresponding to most of the world's currently published literature and many other types of information are publicly available through online systems. Scientific databases that give references for publications are numerous and widely used; scientific numeric databases that are open to the public are far fewer and less used. Online retrieval systems are becoming easier to use as a result of the introduction of artificial intelligence techniques and user-friendly front ends and gateways. Issues related to electronic databases include public-private sector competition, transborder data flow, copyright, downloading, and the changing roles in database generation and processing. Online databases for use by the general public have been available for little more than a decade, but in that short time the volume of items available has grown more than a thousandfold. Although limited in subject coverage initially, there are now databases that appeal to users in virtually all disciplines. The number of services has increased as has the value received per dollar (even though the price per hour for given databases may have doubled in 10 years, the number of records in the databases has far more than doubled). Online systems have become much more sophisticated and at the same time intermediary systems have been developed to make them eas
