An in situ study of photosynthetic oxygen exchange and electron transport rate in the marine macroalga Ulva lactuca (Chlorophyta).  

Science.gov (United States)

Direct comparisons between photosynthetic O(2) evolution rate and electron transport rate (ETR) were made in situ over 24 h using the benthic macroalga Ulva lactuca (Chlorophyta), growing and measured at a depth of 1.8 m, where the midday irradiance rose to 400-600 mumol photons m(-2) s(-1). O(2) exchange was measured with a 5-chamber data-logging apparatus and ETR with a submersible pulse amplitude modulated (PAM) fluorometer (Diving-PAM). Steady-state quantum yield ((F(m)'-F(t))/F(m)') decreased from 0.7 during the morning to 0.45 at midday, followed by some recovery in the late afternoon. At low to medium irradiances (0-300 mumol photons m(-2) s(-1)), there was a significant correlation between O(2) evolution and ETR, but at higher irradiances, ETR continued to increase steadily, while O(2) evolution tended towards an asymptote. However at high irradiance levels (600-1200 mumol photons m(-2) s(-1)) ETR was significantly lowered. Two methods of measuring ETR, based on either diel ambient light levels and fluorescence yields or rapid light curves, gave similar results at low to moderate irradiance levels. Nutrient enrichment (increases in [NO(3) (-)], [NH(4) (+)] and [HPO(4) (2-)] of 5- to 15-fold over ambient concentrations) resulted in an increase, within hours, in photosynthetic rates measured by both ETR and O(2) evolution techniques. At low irradiances, approximately 6.5 to 8.2 electrons passed through PS II during the evolution of one molecule of O(2), i.e., up to twice the theoretical minimum number of four. However, in nutrient-enriched treatments this ratio dropped to 5.1. The results indicate that PAM fluorescence can be used as a good indication of the photosynthetic rate only at low to medium irradiances. PMID:16245139

Electronic Resource Management Systems  

Directory of Open Access Journals (Sweden)

Full Text Available Computer applications which deal with electronic resource management (ERM are quite a recent development. They have grown out of the need to manage the burgeoning number of electronic resources particularly electronic journals. Typically, in the early years of e-journal acquisition, library staff provided an easy means of accessing these journals by providing an alphabetical list on a web page. Some went as far as categorising the e-journals by subject and then grouping the journals either on a single web page or by using multiple pages. It didn't take long before it was recognised that it would be more efficient to dynamically generate the pages from a database rather than to continually edit the pages manually. Of course, once the descriptive metadata for an electronic journal was held within a database the next logical step was to provide administrative forms whereby that metadata could be manipulated. This in turn led to demands for incorporating more information and more functionality into the developing application.

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.

Simple Sequence Repeats (SSRs) or microsatellites constitute a significant portion of genomes however; their significance in organellar genomes has not been completely understood. The availability of organelle genome sequences allows us to understand the organization of SSRs in their genic and intergenic regions. In the present work, SSRs were identified and categorized in 14 mitochondrial and 22 chloroplast genomes of algal species belonging to Chlorophyta. Based on the study, it was observed that number of SSRs in non-coding region were more as compared to coding region and frequency of mononucleotides repeats were highest followed by dinucleotides in both mitochondrial and chloroplast genomes. It was also observed that maximum number of SSRs was found in genes encoding for beta subunit of RNA polymerase in chloroplast genomes and NADH dehydrogenase in mitochondrial genomes. This is the first and original report on whole genomes sequence analysis of organellar genomes of green algae. PMID:22493532

Developing an Electronic Resource Management System: Verde from Ex Libris  

Directory of Open Access Journals (Sweden)

Full Text Available Rapid growth in the number of electronic resources and the complexity of managing e-collections has posed new challenges for libraries and hence requires the development of new tools. To meet this need, Ex Libris is developing a new product, an electronic resource management (ERM system. The development process began in 2002 and has benefited from the company's 25 years of experience in providing libraries with various products - an integrated library system, digital asset management system, library portal, and link server. Working with an international focus group and development partners and interacting with the Digital Library Federation's Electronic Resource Management Initiative (DLF ERMI committee, Ex Libris explored the various aspects of the e-resource life cycle. As a result, the Ex Libris ERM system was designed to address the issues raised through this collaboration and the DLF requirements. The interface of the system represents all of its components; it includes navigation options and facilitates workflows that support the various activities that librarians perform when dealing with electronic resources. This paper describes the development process of the Ex Libris ERM system. The emphasis is on the particular functionality required for managing e-resources and the ways in which existing systems in the library arena can handle specific tasks.

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.

Desiccation Induces Accumulations of Antheraxanthin and Zeaxanthin in Intertidal Macro-Alga Ulva pertusa (Chlorophyta)  

Science.gov (United States)

For plants and algae, exposure to high light levels is deleterious to their photosynthetic machineries. It also can accelerate water evaporation and thus potentially lead to drought stress. Most photosynthetic organisms protect themselves against high light caused photodamages by xanthophyll cycle-dependent thermal energy dissipation. It is generally accepted that high light activates xanthophyll cycle. However, the relationship between xanthophyll cycle and drought stress remains ambiguous. Herein, Ulva pertusa (Chlorophyta), a representative perennial intertidal macro-algae species with high drought-tolerant capabilities and simple structures, was used to investigate the operation of xanthophyll cycle during desiccation in air. The results indicate that desiccation under dim light induced accumulation of antheraxanthin (Ax) and zeaxanthin (Zx) at the expense of violaxanthin (Vx). This accumulation could be arrested by dithiothreitol completely and by uncoupler (carbonyl cyanide p-trifluoromethoxyphenylhydrazone) partially, implying the participation of Vx de-epoxidase in conversion of Vx to Ax and Zx. Treatment with inhibitors of electron transport along thylakoid membrane, e.g. DCMU, PG and DBMIB, did not significantly arrest desiccation-induced accumulation of Ax and Zx. We propose that for U. pertusa, besides excess light, desiccation itself could also induce accumulation of Ax and Zx. This accumulation could proceed without electron transport along thylakoid membrane, and is possibly resulting from the reduction of thylakoid lumen volume during desiccation. Considering the pleiotropic effects of Ax and Zx, accumulated Ax and Zx may function in protecting thylakoid membrane and enhancing thermal quenching during emersion in air.

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.

Phylogenetic analysis identifies the invertebrate pathogen Helicosporidium sp. as a green alga (Chlorophyta).  

Science.gov (United States)

Historically, the invertebrate pathogens of the genus Helicosporidium were considered to be either protozoa or fungi, but the taxonomic position of this group has not been considered since 1931. Recently, a Helicosporidium sp., isolated from the blackfly Simulium jonesi Stone & Snoddy (Diptera: Simuliidae), has been amplified in the heterologous host Helicoverpa zea. Genomic DNA has been extracted from gradient-purified cysts. The 185, 28S and 5.8S regions of the Helicosporidium rDNA, as well as partial sequences of the actin and beta-tubulin genes, were amplified by PCR and sequenced. Comparative analysis of these nucleotide sequences was performed using neighbour-joining and maximum-parsimony methods. All inferred phylogenetic trees placed Helicosporidium sp. among the green algae (Chlorophyta), and this association was supported by bootstrap and parsimony jackknife values. Phylogenetic analysis focused on the green algae depicted Helicosporidium sp. as a close relative of Prototheca wickerhamii and Prototheca zopfii (Chlorophyta, Trebouxiophyceae), two achlorophylous, pathogenic green algae. On the basis of this phylogenetic analysis, Helicosporidium sp. is clearly neither a protist nor a fungus, but appears to be the first described algal invertebrate pathogen. These conclusions lead us to propose the transfer of the genus Helicosporidium to Chlorophyta, Trebouxiophyceae. PMID:11837312

Utilization of bio-resources by low energy electron beam  

International Nuclear Information System (INIS)

Utilization of bio-resources by radiation has been investigated for recycling the natural resources and reducing the environmental pollution. Polysaccharides such as chitosan and sodium alginate were easily degraded by irradiation and induced various kinds of biological activities, i.g. anti-microbial activity, promotion of plant growth, suppression of heavy metal stress, phytoalexins induction. Radiation degraded chitosan was effective to enhance the growth of plants in tissue culture. It was demonstrated that the liquid sample irradiation system using low energy EB was effective for the preparation of degraded polysaccharides. Methylcellulose (MC) can be crosslinked under certain radiation condition as same as carboxymethylcellulose (CMC) and produced the biodegradable hydrogel for medical and agricultural use. Treatment of soybean seeds by low energy EB enhanced the growth and the number of rhizobia on the root. (author)

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 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.

MULER: Building an Electronic Resource Management (ERM Solution at York University  

Directory of Open Access Journals (Sweden)

Full Text Available Many university libraries now utilize an Electronic Resource Management (ERM system to assist with operations related to electronic resources. An ERM is a relational database containing information such as suppliers, costs, holdings, and renewal dates for electronic resources, both at the database and title levels. While commercial ERM products are widely available, some institutions are custom building their own ERM in- house. This article describes how York University in Toronto, Canada, did just that by building a system called Managing University Library Electronic Resources (MULER. The article details the background and history of how electronic resources were managed pre-MULER; why a new ERM was needed; the planning process; the current and innovative functions of MULER, including integration of MULER data into York University Libraries search and discovery layer, Vufind; subject tagging in MULER; new functions to be added; and lessons learned from the project. Positive and negative implications of choosing an in-house project over paying for a commercial product are also discussed.

Connecting knowledge resources to the veterinary electronic health record: opportunities for learning at point of care.  

Science.gov (United States)

Electronic health records (EHRs) provide clinical learning opportunities through quick and contextual linkage of patient signalment, symptom, and diagnosis data with knowledge resources covering tests, drugs, conditions, procedures, and client instructions. This paper introduces the EHR standards for linkage and the partners-practitioners, content publishers, and software developers-necessary to leverage this possibility in veterinary medicine. The efforts of the American Animal Hospital Association (AAHA) Electronic Health Records Task Force to partner with veterinary practice management systems to improve the use of controlled vocabulary is a first step in the development of standards for sharing knowledge at the point of care. The Veterinary Medical Libraries Section (VMLS) of the Medical Library Association's Task Force on Connecting the Veterinary Health Record to Information Resources compiled a list of resources of potential use at point of care. Resource details were drawn from product Web sites and organized by a metric used to evaluate medical point-of-care resources. Additional information was gathered from questions sent by e-mail and follow-up interviews with two practitioners, a hospital network, two software developers, and three publishers. Veterinarians with electronic records use a variety of information resources that are not linked to their software. Systems lack the infrastructure to use the Infobutton standard that has been gaining popularity in human EHRs. While some veterinary knowledge resources are digital, publisher sites and responses do not indicate a Web-based linkage of veterinary resources with EHRs. In order to facilitate lifelong learning and evidence-based practice, veterinarians and educators of future practitioners must demonstrate to veterinary practice software developers and publishers a clinically-based need to connect knowledge resources to veterinary EHRs.

Disseminating context-specific access to online knowledge resources within electronic health record systems.  

Science.gov (United States)

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. PMID:23920641

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.

The National Site Licensing of Electronic Resources: An Institutional Perspective  

Directory of Open Access Journals (Sweden)

Full Text Available While academic libraries in most countries are struggling to negotiate with publishers and vendors individually or collaboratively via consortia, a few countries have experimented with a different model, national site licensing (NSL. Because NSL often involves government and large-scale collaboration, it has the potential to solve many problems in the complex licensing world. However, not many nations have adopted it. This study uses historical research approach and the comparative case study research method to explore the seemingly low level of adoption. The cases include the Canadian National Site Licensing Project (CNSLP, the United Kingdom’s National Electronic Site Licensing Initiative (NESLI, and the United States, which has not adopted NSL. The theoretical framework guiding the research design and data collection is W. Richard Scott’s institutional theory, which utilizes three supporting pillars—regulative, normative, and cultural-cognitive—to analyze institutional processes. In this study, the regulative pillar and the normative pillar of NSL adoption— an institutional construction and change—are examined. Data were collected from monographs, research articles, government documents, and relevant websites. Based on the analysis of these cases, a preliminary model is proposed for the adoption of NSL. The factors that support a country’s adoption of NSL include the need for new institutions, a centralized educational policy-making system and funding system, supportive political trends, and the tradition of cooperation. The factors that may prevent a country from adopting NSL include decentralized educational policy and funding, diversity and the large number of institutions, the concern for the “Big Deal,” and the concern for monopoly.

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.

Power resource management and low-power remote wireless RF electronics  

Science.gov (United States)

Battery power resource management becomes a critical issue in the case of self-powered remote wireless RF electronics, where the basic parameter is time of system operation before battery recharging or battery replacement. In such cases, very often related to physical protection against antitampering (AT), proper theoretical modeling of a battery driven power supply in the context of a given digital electronic system is of utmost importance. Such modeling should include various types of batteries (primary and secondary), various self-discharge processes in different temperatures, and even energy harvesting, the latter to supply power for long-term content, low-power electronic subsystems. In this paper we analyze simple modeling of resource power management, including variations of all of these parameters and energy harvesting.

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

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

International Nuclear Information System (INIS)

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  

Science.gov (United States)

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.

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.

Copper-induced synthesis of ascorbate, glutathione and phytochelatins in the marine alga Ulva compressa (Chlorophyta).  

Science.gov (United States)

In order to analyze the synthesis of antioxidant and heavy metal-chelating compounds in response to copper stress, the marine alga Ulva compressa (Chlorophyta) was exposed to 10 ?M copper for 7 days and treated with inhibitors of ASC synthesis, lycorine, and GSH synthesis, buthionine sulfoximine (BSO). The levels of ascorbate, in its reduced (ASC) and oxidized (DHA) forms, glutathione, in its reduced (GSH) and oxidized (GSSG) forms, and phytochelatins (PCs) were determined as well as activities of enzymes involved in ASC synthesis, L-galactose dehydrogenase (GDH) and L-galactono 1,4 lactone dehydrogenase (GLDH), and in GSH synthesis, ?-glutamylcysteine synthase (?-GCS) and glutathione synthase (GS). The level of ASC rapidly decreased to reach a minimum at day 1 that remained low until day 7, DHA decreased until day 1 but slowly increased up to day 7 and its accumulation was inhibited by lycorine. In addition, GSH level increased to reach a maximal level at day 5 and GSSG increased up to day 7 and their accumulation was inhibited by BSO. Activities of GDH and GLDH increased until day 7 and GLDH was inhibited by lycorine. Moreover, activities of ?-GCS and GS increased until day 7 and ?-GCS was inhibited by BSO. Furthermore, PC2, PC3 and PC4, increased until day 7 and their accumulation was inhibited by BSO. Thus, copper induced the synthesis of ascorbate, glutathione and PCs in U. compressa suggesting that these compounds are involved in copper tolerance. Interestingly, U. compressa is, until now, the only ulvophyte showing ASC, GSH and PCs synthesis in response to copper excess. PMID:22153245

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

Science.gov (United States)

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. PMID:22993131

SAGES: A Suite of Freely-Available Software Tools for Electronic Disease Surveillance in Resource-Limited Settings  

Science.gov (United States)

Public health surveillance is undergoing a revolution driven by advances in the field of information technology. Many countries have experienced vast improvements in the collection, ingestion, analysis, visualization, and dissemination of public health data. Resource-limited countries have lagged behind due to challenges in information technology infrastructure, public health resources, and the costs of proprietary software. The Suite for Automated Global Electronic bioSurveillance (SAGES) is a collection of modular, flexible, freely-available software tools for electronic disease surveillance in resource-limited settings. One or more SAGES tools may be used in concert with existing surveillance applications or the SAGES tools may be used en masse for an end-to-end biosurveillance capability. This flexibility allows for the development of an inexpensive, customized, and sustainable disease surveillance system. The ability to rapidly assess anomalous disease activity may lead to more efficient use of limited resources and better compliance with World Health Organization International Health Regulations.

Isolation and characterization of a single-copy actin gene from a sterile mutant of Ulva pertusa (Ulvales, Chlorophyta).  

Science.gov (United States)

We constructed a cDNA library from sterile Ulva pertusa (Ulvales, Chlorophyta), and isolated and characterized a full-length cDNA clone encoding actin. The actin (ACT) cDNA consisted of 1487 nucleotides (nt) and had an open reading frame (ORF) encoding a polypeptide of 377 amino acid (AA) residues. The ACT gene had one intron in the 5'-untranslated region and three introns in the coding region. Transcription started 26 nt downstream of the putative TATA box. A potential polyadenylation signal, TGTAG, was located 100 nt downstream of the terminator codon, TAG. Amino acid alignment with actins from various algae and land plants showed that sterile U. pertusa actin was more similar to actins from Chlorophyta, Phaeophyta, Euglenophyta, and higher plants (over 76.9%) than to actins from Rhodophyta. Southern blot analysis indicated that the sterile U. pertusa genome has only a single actin-encoding gene. Thalli grown on a 12D/12L photoperiod increased in surface area some two-fold over 24 h regardless of the nutritional conditions. The growth rate of thalli during the light period was significantly higher than that during the dark period. Northern hybridization indicated that the expression of actin mRNA was induced and repressed by the light and dark treatments, respectively. These results suggest that the U. pertusa cell division cycle has a periodicity of 24 h and that the ACT gene is highly transcribed during cell growth and development in the light period.

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.

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

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in portuguese 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 fl [...] uorescência (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. Abstract in english 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 probab

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.

Internet and electronic resources for inflammatory bowel disease: a primer for providers and patients.  

Science.gov (United States)

Patients with inflammatory bowel disease (IBD) are increasingly turning to the Internet to research their condition and engage in discourse on their experiences. This has resulted in new dynamics in the relationship between providers and their patients, with misinformation and advertising potentially presenting barriers to the cooperative patient-provider partnership. This article addresses important issues of online IBD-related health information and social media activity, such as quality, reliability, objectivity, and privacy. We reviewed the medical literature on the quality of online information provided to IBD patients, and summarized the most commonly accessed Websites related to IBD. We also assessed the activity on popular social media sites (such as Facebook, Twitter, and YouTube), and evaluated currently available applications for use by IBD patients and providers on mobile phones and tablets. Through our review of the literature and currently available resources, we developed a list of recommended online resources to strengthen patient participation in their care by providing reliable, comprehensive educational material.

Development and evolution of The Knowledge Hub for Pathology and related electronic resources.  

Science.gov (United States)

The Knowledge Hub for Pathology was created to provide authenticated and validated knowledge for United States and Canadian Academy of Pathology members and pathologists worldwide with access to the Web. Using the material presented at the annual meeting of the United States and Canadian Academy of Pathology with existing selection and review procedures ensured that these criteria were met without added costly procedures. Further submissions for courses and research papers are provided in electronic format and funded by universities and hospitals for their creation; thus, the principal costs borne by the United States and Canadian Academy of Pathology are Web site-posting costs. Use has escalated rapidly from 2 million hits in 2002 to 51 million in 2009 with use by 35,000 pathologists from now a total of 180 countries. This true "freemium" model is a successful process as are more traditional continuing professional development course structures such as Anatomic Pathology Electronic Case Series, a "premium" model for learning electronically also sponsored by the United States and Canadian Academy of Pathology.

Comparison of plastid 16S rRNA (rrn16) genes from Helicosporidium spp.: evidence supporting the reclassification of Helicosporidia as green algae (Chlorophyta).  

Science.gov (United States)

The Helicosporidia are invertebrate pathogens that have recently been identified as non-photosynthetic green algae (Chlorophyta). In order to confirm the algal nature of the genus Helicosporidium, the presence of a retained chloroplast genome in Helicosporidia cells was investigated. Fragments homologous to plastid 16S rRNA (rrn16) genes were amplified successfully from cellular DNA extracted from two different Helicosporidium isolates. The fragment sequences are 1269 and 1266 bp long, are very AT-rich (60.7 %) and are similar to homologous genes sequenced from non-photosynthetic green algae. Maximum-parsimony, maximum-likelihood and neighbour-joining methods were used to infer phylogenetic trees from an rrn16 sequence alignment. All trees depicted the Helicosporidia as sister taxa to the non-photosynthetic, pathogenic alga Prototheca zopfii. Moreover, the trees identified Helicosporidium spp. as members of a clade that included the heterotrophic species Prototheca spp. and the mesotrophic species Chlorella protothecoides. The clade is always strongly supported by bootstrap values, suggesting that all these organisms share a most recent common ancestor. Phylogenetic analyses inferred from plastid 16S rRNA genes confirmed that the Helicosporidia are non-photosynthetic green algae, close relatives of the genus Prototheca (Chlorophyta, Trebouxiophyceae). Such phylogenetic affinities suggest that Helicosporidium spp. are likely to possess Prototheca-like organelles and organelle genomes. PMID:14657099

"3"1P-NMR differentiation between intracellular phosphate pools in Cosmarium (chlorophyta)  

International Nuclear Information System (INIS)

"3"1P 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 "3"1P-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 "3"1P-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. "3"1P-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

Green Supply Chain Collaboration for Fashionable Consumer Electronics Products under Third-Party Power Intervention—A Resource Dependence Perspective  

Directory of Open Access Journals (Sweden)

Full Text Available Under third-party power intervention (TPPI, which increases uncertainty in task environments, complex channel power interplays and restructuring are indispensable among green supply chain members as they move toward sustainable collaborative relationships for increased viability and competitive advantage. From the resource dependence perspective, this work presents a novel conceptual model to investigate the influence of political and social power on channel power restructuring and induced green supply chain collaboration in brander-retailer bidirectional green supply chains of fashionable consumer electronics products (FCEPs. An FCEP refers to the consumer electronics product (e.g., personal computers, mobile phones, computer notebooks, and game consoles with the features of a well-known brand associated, a short product lifecycle, timely and fashionable design fit for market trends, and quick responsiveness to the variations of market demands. The proposed model is tested empirically using questionnaire data obtained from retailers in the FCEP brander-retailer distribution channels. Analytical results reveal that as an extension of political and social power, TPPI positively affects the reciprocal interdependence of dyadic members and reduces power asymmetry, thereby enhancing the collaborative relationship of dyadic members and leading to improved green supply chain performance. Therein, reciprocal interdependence underlying collaborative relationship is the key to reducing the external environmental uncertainties in the TPPI context.

A close-up view on ITS2 evolution and speciation - a case study in the Ulvophyceae (Chlorophyta, Viridiplantae  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background The second Internal Transcriber Spacer (ITS2 is a fast evolving part of the nuclear-encoded rRNA operon located between the 5.8S and 28S rRNA genes. Based on crossing experiments it has been proposed that even a single Compensatory Base Change (CBC in helices 2 and 3 of the ITS2 indicates sexual incompatibility and thus separates biological species. Taxa without any CBC in these ITS2 regions were designated as a 'CBC clade'. However, in depth comparative analyses of ITS2 secondary structures, ITS2 phylogeny, the origin of CBCs, and their relationship to biological species have rarely been performed. To gain 'close-up' insights into ITS2 evolution, (1 86 sequences of ITS2 including secondary structures have been investigated in the green algal order Ulvales (Chlorophyta, Viridiplantae, (2 after recording all existing substitutions, CBCs and hemi-CBCs (hCBCs were mapped upon the ITS2 phylogeny, rather than merely comparing ITS2 characters among pairs of taxa, and (3 the relation between CBCs, hCBCs, CBC clades, and the taxonomic level of organisms was investigated in detail. Results High sequence and length conservation allowed the generation of an ITS2 consensus secondary structure, and introduction of a novel numbering system of ITS2 nucleotides and base pairs. Alignments and analyses were based on this structural information, leading to the following results: (1 in the Ulvales, the presence of a CBC is not linked to any particular taxonomic level, (2 most CBC 'clades' sensu Coleman are paraphyletic, and should rather be termed CBC grades. (3 the phenetic approach of pairwise comparison of sequences can be misleading, and thus, CBCs/hCBCs must be investigated in their evolutionary context, including homoplasy events (4 CBCs and hCBCs in ITS2 helices evolved independently, and we found no evidence for a CBC that originated via a two-fold hCBC substitution. Conclusions Our case study revealed several discrepancies between ITS2 evolution in the Ulvales and generally accepted assumptions underlying ITS2 evolution as e.g. the CBC clade concept. Therefore, we developed a suite of methods providing a critical 'close-up' view into ITS2 evolution by directly tracing the evolutionary history of individual positions, and we caution against a non-critical use of the ITS2 CBC clade concept for species delimitation.

Patterns of asexual reproduction in Nannochloris bacillaris and Marvania geminata (Chlorophyta, Trebouxiophyceae).  

Science.gov (United States)

Non-flagellated vegetative green algae of the Trebouxiophyceae propagate mainly by autosporulation. In this manner, the mother cell wall is shed following division of the protoplast in each round of cell division. Binary fission type Nannochloris and budding type Marvania are also included in the Trebouxiophyceae. Phylogenetic trees based on the actin sequences of Trebouxiophyceae members revealed that the binary fission type Nannochloris bacillaris and the budding type Marvania geminata are closely related in a distal monophyletic group. Our results suggest that autosporulation is the ancestral mode of cell division in Trebouxiophyceae. To elucidate how non-autosporulative mechanisms such as binary fission and budding evolved, we focused on the cleavage of the mother cell wall. Cell wall development was analyzed using a cell wall-specific fluorescent dye, Fluostain I. Exfoliation of the mother cell wall was not observed in either N. bacillaris or M. geminata. We then compared the two algae by transmission electron microscopy with rapid freeze fixation and freeze substitution; in both algae, the mother cell wall was cleaved at the site of cell division, but remained adhered to the daughter cell wall. In N. bacillaris, the cleaved mother cell wall gradually degenerated and was not observed in the next cell cycle. In contrast, M. geminata daughter cells entered the growth phase of the next cell cycle bearing the mother and grandmother cell walls, causing the uncovered portion of the plane of division to bulge outward. Such a delay in the degeneration and shedding of the mother cell wall probably led to the development of binary fission and budding. PMID:17520279

Identification of copper-induced genes in the marine alga Ulva compressa (Chlorophyta).  

Science.gov (United States)

In order to identify genes/proteins involved in copper tolerance, the marine alga Ulva compressa was cultivated with 10 ?M copper for 3 days. The activities of antioxidant enzymes ascorbate peroxidase (AP), peroxiredoxin (PRX), thioredoxin (TRX), and glutathione-S-transferase (GST) and the level of lipoperoxides were determined in the alga cultivated with and without copper addition. Antioxidant enzyme activities and lipoperoxides level increased in response to copper excess, indicating that the alga was under oxidative stress. A cDNA library was prepared using U. compressa cultivated with 10 ?M copper for 3 days. A total of 3?×?10(4) clones were isolated and 480 clones were sequenced, resulting in 235 non-redundant ESTs, of which 104 encode proteins with known functions. Among them, we identified proteins involved in (1) antioxidant metabolism such as AP, PRX, TRX, GST, and metalothionein (MET), (2) signal transduction, such as calmodulin (CAM), (3) calcium-dependent protein kinase (CDPK) and nucleoside diphosphate kinase (NDK), (4) gene expression, (5) protein synthesis and degradation, and (6) chloroplast and mitochondria electron transport chains. Half of the identified proteins are potentially localized in organelles. The relative level of 18 genes, including those coding for AP, PRX, TRX, GST, MET, CAM, CDPK, and NDK were determined by quantitative RT-PCR in the alga cultivated with 10 ?M copper for 0 to 7 days. Transcript levels increased in response to copper stress and most of them reached a maximum at days 3 and 5. Thus, the selected genes are induced by copper stress and they are probably involved in copper acclimation and tolerance. PMID:20936320

Preliminary study on the responses of three marine algae, Ulva pertusa (Chlorophyta), Gelidium amansii (Rhodophyta) and Sargassum enerve (Phaeophyta), to nitrogen source and its availability  

Science.gov (United States)

An experiment was designed to select economically valuable macroalga species with high nutrient uptake rates. Such species cultured on a large scale could be a potential solution to eutrophication. Three macroalgae species, Ulva pertusa (Chlorophyta), Gelidium amansii (Rhodophyta) and Sargassum enerve (Phaeophyta), were chosen for the experiment because of their economic values and availability. Control and four nitrogen concentrations were achieved by adding NH{4/+} and NO{3/-}. The results indicate that the fresh weights of all species increase faster than that of control after 5 d culture. The fresh weight of Ulva pertusa increases fastest among the 3 species. However, different species show different responses to nitrogen source and its availability. They also show the advantage of using NH{4/+} than using NO{3/-}. U. pertusa grows best and shows higher capability of removing nitrogen at 200µmolL-1, but it has lower economical value. G. amansii has higher economical value but lower capability of removing nitrogen at 200 µmolL-1. The capability of nitrogen assimilation of S. enerve is higher than that of G. amansii at 200µmolL -1, but the former’s increase of fresh weight is lower than those of other two species. Then present preliminary study demonstrates that it is possible to use macroalgae as biofilters and further development of this approach could provide biologically valuable information on the source, fate, and transport of N in marine ecosystems. Caution is needed should we extrapolate these findings to natural environments.

As plantas foram aclimatadas a dois níveis de irrad [...] iância: 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 fotoperíodo 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.

Photosynthesis-irradiance (PI) curves revealed distinct strategies of photoacclimation. 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. Chlorophyll a contents followed the general pattern reported in green algae of higher concentrations under lower irradiance. Dark/light induction curves revealed consistently higher values of potential quantum yield under low irradiance.

Impact of two interventions on timeliness and data quality of an electronic disease surveillance system in a resource limited setting (Peru: a prospective evaluation  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background A timely detection of outbreaks through surveillance is needed in order to prevent future pandemics. However, current surveillance systems may not be prepared to accomplish this goal, especially in resource limited settings. As data quality and timeliness are attributes that improve outbreak detection capacity, we assessed the effect of two interventions on such attributes in Alerta, an electronic disease surveillance system in the Peruvian Navy. Methods 40 Alerta reporting units (18 clinics and 22 ships were included in a 12-week prospective evaluation project. After a short refresher course on the notification process, units were randomly assigned to either a phone, visit or control group. Phone group sites were called three hours before the biweekly reporting deadline if they had not sent their report. Visit group sites received supervision visits on weeks 4 & 8, but no phone calls. The control group sites were not contacted by phone or visited. Timeliness and data quality were assessed by calculating the percentage of reports sent on time and percentage of errors per total number of reports, respectively. Results Timeliness improved in the phone group from 64.6% to 84% in clinics (+19.4 [95% CI, +10.3 to +28.6]; p Conclusion Regular phone reminders significantly improved timeliness of reports in clinics and ships, whereas supervision visits led to improved data quality only among clinics. Further investigations are needed to establish the cost-effectiveness and optimal use of each of these strategies.

Merge of terminological resources  

DEFF Research Database (Denmark)

In our globalized world, the amount of cross-national communication increases rapidly, which also calls for easy access to multi-lingual high quality terminological resources. Sharing of terminology resources is currently becoming common practice, and efficient strategies for integration â?? or merging â?? of terminology resources are strongly needed. This paper discusses prerequisites for successful merging with the focus on identification of candidate duplicates of a subject domain found in the resources to be merged, and it describes automatic merging strategies to be applied to such duplicates in electronic terminology resources. Further, some perspectives of manual, supplementary assessment methods supporting the automatic procedures are sketched. Our considerations are primarily based on experience gained in the IATE and EuroTermBank projects, as merging was a much discussed issue in both projects.

Enzymatic regulation of photosynthetic and light-independent carbon fixation in Laminaria setchellii (Phaeophyta, Ulva lactuca (Chlorophyta and Iridaea cordata (Rhodophyta Regulación enzimática de la fotosíntesis y la fijación de carbono en obscuridad por Laminaria setchellii (Phaeophyta, Ulva lactuca (Chlorophyta e Iridaea cordata (Rhodophyta  

Directory of Open Access Journals (Sweden)

Full Text Available Carbon is acquired through photosynthetic and non-photosynthetic processes in marine algae. However, little is known about the biochemical regulation of these metabolic pathways along the thallus of seaweeds. Consequently, the objective of this study was to assess the distribution of in vivo carboxylation pathways and to relate them to the in vitro activity of ribulose 1,5-bisphosphate carboxylase/oxygenase (RUBISCO, phosphoenolpyruvate carboxykinase (PEPCK, and phosphoenolpyruvate carboxylase (PEPC in the Phaeophyte Laminaria setchellii, the Chlorophyte Ulva lactuca, and the Rhodophyte Iridaea cordata. Chlorophyll-a levels did not vary in U. lactuca and I. cordata. However, pigment levels were significantly lower in the meristematic region of L. setchellii probably as a result of a lack of differentiation of the chloroplasts in this region. Similarly, net photosynthesis did not vary in the thallus of U. lactuca and I. cordata, while it increased from the stipe and meristem towards the lamina of L. setchellii. In contrast to photosynthesis, light-independent carbon fixation rates were significantly greater in the meristematic region of L. setchellii suggesting a compensating mechanism for carbon incorporation in photosynthetically limited tissue. The activity of RUBISCO and PEPCK followed a pattern similar to that of in vivo carboxylation processes indicating that in vivo carbon assimilation is regulated by the activity of the carboxylating enzymes throughout the thallus of L. setchelliiLa incorporación de carbono en algas marinas se lleva a cabo mediante procesos fotosintéticos y no-fotosintéticos. Sin embargo, poco se sabe sobre la regulación bioquímica de estas rutas metabólicas en el tejido de algas marinas. En consecuencia, el objetivo de este estudio fue el de evaluar la distribución de la carboxilación in vivo y relacionarlas a la actividad in vitro de ribulosa 1,5-bisfosfato carboxilasa/oxigenasa (RUBISCO, fosfoenolpiruvato carboxikinasa (PEPCK y fosfoenolpiruvato carboxilasa (PEPC en la Phaeophyta Laminaria setchellii, la Chlorophyta Ulva lactuca y la Rhodophyta Iridaea cordata. Los niveles de clorofila-a no variaron en U. lactuca e I. cordata. Sin embargo, los niveles de pigmentos fueron significativamente menores en la región meristemática de L. setchellii probablemente debido a una falta de diferenciación de los cloroplastos de esta región. De una manera similar, la fotosíntesis neta no varió en el talo de U. lactuca e I. cordata, mientras que se incrementó desde el estipe y el meristemo hacia la lámina de L. setchellii. En contraste con la fotosíntesis, la fijación de carbono en oscuridad fue significantemente mayor en la zona meristemática de L. setchellii sugiriendo un mecanismo para la compensación de la incorporación de carbono en tejido fotosintéticamente limitado. 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

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.

The Biomedical Resource Ontology (BRO) to Enable Resource Discovery in Clinical and Translational Research  

Digital Repository Infrastructure Vision for European Research (DRIVER)

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...

Co-occurring increases of calcium and organellar reactive oxygen species determine differential activation of antioxidant and defense enzymes in Ulva compressa (Chlorophyta) exposed to copper excess.  

Science.gov (United States)

In order to analyse copper-induced calcium release and (reactive oxygen species) ROS accumulation and their role in antioxidant and defense enzymes activation, the marine alga Ulva compressa was exposed to 10 µM copper for 7 d. The level of calcium, extracellular hydrogen peroxide (eHP), intracellular hydrogen peroxide (iHP) and superoxide anions (SA) as well as the activities of ascorbate peroxidase (AP), glutathione reductase (GR), glutathione-S-transferase (GST), phenylalanine ammonia lyase (PAL) and lipoxygenase (LOX) were determined. Calcium release showed a triphasic pattern with peaks at 2, 3 and 12 h. The second peak was coincident with increases in eHP and iHP and the third peak with the second increase of iHP. A delayed wave of SA occurred after day 3 and was not accompanied by calcium release. The accumulation of iHP and SA was mainly inhibited by organellar electron transport chains inhibitors (OETCI), whereas calcium release was inhibited by ryanodine. AP activation ceased almost completely after the use of OETCI. On the other hand, GR and GST activities were partially inhibited, whereas defense enzymes were not inhibited. In contrast, PAL and LOX were inhibited by ryanodine, whereas AP was not inhibited. Thus, copper stress induces calcium release and organellar ROS accumulation that determine the differential activation of antioxidant and defense enzymes. PMID:20444222

Uranium resources  

International Nuclear Information System (INIS)

This is a press release issued by the OECD on 9th March 1976. It is stated that the steep increases in demand for uranium foreseen in and beyond the 1980's, with doubling times of the order of six to seven years, will inevitably create formidable problems for the industry. Further substantial efforts will be needed in prospecting for new uranium reserves. Information is given in tabular or graphical form on the following: reasonably assured resources, country by country; uranium production capacities, country by country; world nuclear power growth; world annual uranium requirements; world annual separative requirements; world annual light water reactor fuel reprocessing requirements; distribution of reactor types (LWR, SGHWR, AGR, HWR, HJR, GG, FBR); and world fuel cycle capital requirements. The information is based on the latest report on Uranium Resources Production and Demand, jointly issued by the OECD's Nuclear Energy Agency (NEA) and the International Atomic Energy Agency. (U.K.)

Water resources  

International Nuclear Information System (INIS)

The report entitled Climate Change Impacts and Adaptation : A Canadian Perspective, presents a summary of research regarding the impacts of climate change on key sectors over the past five years as it relates to Canada. This chapter on water resources describes how climate change will affect the supply of water in Canada. Water is one of Canada's greatest resources, which contributes about $7.5 to 23 billion per year to the Canadian economy. The decisions taken to adapt to climate change within the water resources sector will have profound implications in many other areas such as agriculture, human health, transportation and industry. The water related problems include water quality issues that relate to water shortages from droughts, or excesses from floods. The Intergovernmental Panel on Climate Change forecasts an increase in global average surface air temperatures of 1.4 to 5.8 degrees C by 2100. Such a change would impact the hydrological cycle, affecting runoff, evaporation patterns, and the amount of water stored in glaciers, lakes, wetlands and groundwater. The uncertainty as to the magnitude of these changes is due to the difficulty that climate models have in projecting future changes in regional precipitation patterns and extreme events. This chapter presents potential impacts of climate change on water resources in the Yukon, British Columbia, the Prairies, the Great Lakes basin, the Atlantic provinces, and the Arctic and Subarctic. The associated concerns for each region were highlighted. Adaptation research has focused on the impacts of supply and demand, and on options to adapt to these impacts. 60 refs., 2 tabs., 1 fig

Developable resources  

Energy Technology Data Exchange (ETDEWEB)

In the United States, it has become the conventional wisdom that all developable conventional hydropower resources have been exhausted. Studies by the US Department of Energy (DOE) and other agencies find differently. The root of disagreement may lie in the definition of what is developable. Environmental special interest groups now define developable hydropower sites as those having zero effect on the environment. As a result they conclude there are no additional developable hydropower sites. By contrast, the definition used by DOE and others is broader as it balances economic, technical, and environmental factors in accordance with the Federal Power Act.

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.

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

Alternative Electron Transports Participate in the Maintenance of Violaxanthin De-Epoxidase Activity of Ulva sp. under Low Irradiance  

Science.gov (United States)

The xanthophyll cycle (Xc), which involves violaxanthin de-epoxidase (VDE) and the zeaxanthin epoxidase (ZEP), is one of the most rapid and efficient responses of plant and algae to high irradiance. High light intensity can activate VDE to convert violaxanthin (Vx) to zeaxanthin (Zx) via antheraxanthin (Ax). However, it remains unclear whether VDE remains active under low light or dark conditions when there is no significant accumulation of Ax and Zx, and if so, how the ?pH required for activation of VDE is built. In this study, we used salicylaldoxime (SA) to inhibit ZEP activity in the intertidal macro-algae Ulva sp. (Ulvales, Chlorophyta) and then characterized VDE under low light and dark conditions with various metabolic inhibitors. With inhibition of ZEP by SA, VDE remained active under low light and dark conditions, as indicated by large accumulations of Ax and Zx at the expense of Vx. When PSII-mediated linear electron transport systems were completely inhibited by SA and DCMU, alternative electron transport systems (i.e., cyclic electron transport and chlororespiration) could maintain VDE activity. Furthermore, accumulations of Ax and Zx decreased significantly when SA, DCMU, or DBMIB together with an inhibitor of chlororespiration (i.e., propyl gallate (PG)) were applied to Ulva sp. This result suggests that chlororespiration not only participates in the build-up of the necessary ?pH, but that it also possibly influences VDE activity indirectly by diminishing the oxygen level in the chloroplast.

INTEGRATED WATER RESOURCES MANAGEMENT  

Directory of Open Access Journals (Sweden)

Full Text Available Nowadays, the highest priority issue of water resources management is supply of increasing water demand with limited water resources. Water resources are a basis of sustainable development, so sustainable approach should be based on usage and management of water resources. In the twenty first century, the world is faced with a major water crisis. And the problems are originated from deficiencies and errors in the management of water resources. Thus, sustainable use of water resources is crucial for humanity. The sustainable development is defined as supply objectives and needs of today without jeopardizing objectives and demands of future generations. The long-term objectives instead of short-term ones should be considered in the assessment of water resources. Water resources are handled as a whole in basin management. This approachment constitutes the notion of integrated water resources management.

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.

Hard electronics; Hard electronics  

Energy Technology Data Exchange (ETDEWEB)

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.

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.

Self managing experiment resources  

Science.gov (United States)

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. With a renewed Central Information Schema hosting all resources metadata and a Status System (Resource Status System) delivering real time information, the system controls the resources topology, independently of the resource types. The Resource Status System applies data mining techniques against all possible information sources available and assesses the status changes, that are then propagated to the topology description. Obviously, giving full control to such an automated system is not risk-free. Therefore, in order to minimise the probability of misbehavior, a battery of tests has been developed in order to certify the correctness of its assessments. We will demonstrate the performance and efficiency of such a system in terms of cost reduction and reliability.

Reliability criteria selection for integrated resource planning  

International Nuclear Information System (INIS)

A study was conducted on the selection of a generating system reliability criterion that ensures a reasonable continuity of supply while minimizing the total costs to utility customers. The study was conducted using the Institute for Electronic and Electrical Engineers (IEEE) reliability test system as the study system. The study inputs and results for conditions and load forecast data, new supply resources data, demand-side management resource data, resource planning criterion, criterion value selection, supply side development, integrated resource development, and best criterion values, are tabulated and discussed. Preliminary conclusions are drawn as follows. In the case of integrated resource planning, the selection of the best value for a given type of reliability criterion can be done using methods similar to those used for supply side planning. The reliability criteria values previously used for supply side planning may not be economically justified when integrated resource planning is used. Utilities may have to revise and adopt new, and perhaps lower supply reliability criteria for integrated resource planning. More complex reliability criteria, such as energy related indices, which take into account the magnitude, frequency and duration of the expected interruptions are better adapted than the simpler capacity-based reliability criteria such as loss of load expectation. 7 refs., 5 figs., 10 tabs

Another companion document published under separate cover, the Resource Program Public Comment Summary and BPA's Response, provides a detailed summary of public comments on the Draft 1990 Resource Program and BPA's response to those comments. For a thorough understanding of how BPA arrived at the following conclusions, all three documents should be consulted. The 1990 Resource Program describes the actions Bonneville Power Administration (BPA) will take to develop new resources to meet the power requirements of its customers. The main focus is to determine what BPA should do in Fiscal Years (FY's) 1992 and 1993. This document presents Energy Resource budgets for these years. However, much care has been taken to define near-term actions aimed at meeting BPA's long-term resource needs. consequently, proposed program actions are presented for FY's 1994 through 1997. In addition, the 1990 Resource Program addresses some resource-related policy issues.

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

Virtual resource development in the glycosciences.  

Science.gov (United States)

The development of Internet-based virtual resources is a relatively new area of scientific and technical activity that is currently undergoing rapid expansion. Major factors fuelling recent growth include the emergence of multimedia capabilities through the rapid evolution of the World Wide Web, the reduction in cost of high quality personal computers and graphics workstations and the provision of mass-marketed provider services. Prior to 1995 the presence of Internet resources in the glycosciences was virtually non-existent. Existing scientific knowledge was primarily made available on the Net through the provision of databases from gopher and ftp sites. A particular example in the glycosciences is the Carbbank database of biological carbohydrate sequences. We will describe here our efforts in 1994-95 in establishing The Glycoscience Network (TGN, http:@ bellatrix.pcl.ox.ac.uk/TGN/). These activities included the establishment of a newsgroup, mailing lists, Web resources and the running of the First Electronic Glycoscience Conference (EGC-1, http:@bellatrix.pcl.ox.ac.uk/egc/). EGC-1 included many novel initiatives in the glycosciences including electronic posters and papers, a Virtual Conference Centre, a Web-based hyperglossary, Virtual Trade and Employment Centres, refereed electronic publishing, and the creation of a Virtual Reality Gallery. We would like to look towards the near future and discuss several initiatives in virtual resource creation that we believe will have significant scientific impact on the glycosciences including the development of bioinformatics-based servers, sophisticated interactive databases, and videoconferencing. Furthermore, we cherish the belief that these resources will foster international scientific collaboration and progress of an extent never previously possible. Finally, we indulge in speculation and make some suggestions on the form and long-term impact of Glycoscience Virtual Resources. We predict that their development may completely reconstruct the scientific environment that we work in as scientists and we reflect on the probable benefits and pitfalls to be encountered.

Resource bounds analysis.  

Digital Repository Infrastructure Vision for European Research (DRIVER)

We present a generic analysis that infers both upper and lower bounds on the usage that a program makes of a set of user-definable resources. The inferred bounds will in general be functions of input data sizes. A resource in our approach is a quite general, user-defined notion which associates a basic cost function with elementary operations.

Quantifying global exergy resources  

International Nuclear Information System (INIS)

Exergy is used as a common currency to assess and compare the reservoirs of theoretically extractable work we call energy resources. Resources consist of matter or energy with properties different from the predominant conditions in the environment. These differences can be classified as physical, chemical, or nuclear exergy. This paper identifies the primary exergy reservoirs that supply exergy to the biosphere and quantifies the intensive and extensive exergy of their derivative secondary reservoirs, or resources. The interconnecting accumulations and flows among these reservoirs are illustrated to show the path of exergy through the terrestrial system from input to its eventual natural or anthropogenic destruction. The results are intended to assist in evaluation of current resource utilization, help guide fundamental research to enable promising new energy technologies, and provide a basis for comparing the resource potential of future energy options that is independent of technology and cost

2006 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 both the Federal system and 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 surplus energy could be marketed to increase revenues. Energy deficits occur when resources are less than loads. These energy deficits will 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. This study incorporates information on Pacific Northwest (PNW) regional retail loads, contract obligations, and contract resources. This loads and resources analysis simulates the operation of the power system in the PNW. The simulated hydro operation incorporates plant characteristics, streamflows, and non-power requirements from the current Pacific Northwest Coordination Agreement (PNCA). Additional resource capability estimates were provided by BPA, PNW Federal agency, public agency, cooperative, U.S. Bureau of Reclamation (USBR), and investor-owned utility (IOU) customers furnished through annual PNUCC data submittals for 2005 and/or direct submittals to BPA. The 2006 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 2006 White Book analysis updates the 2004 White Book. This analysis shows projections of the Federal system and region's yearly average annual energy consumption and resource availability for the study period, OY 2007-2016. The study also presents projections of Federal system and region expected 1-hour monthly peak demand, monthly energy demand, monthly 1-hour peak generating capability, and monthly energy generation for OY 2007, 2011, and 2016. BPA is investigating a new approach in capacity planning depicting the monthly Federal system 120-hour peak generating capability and 120-hour peak surplus/deficit for OY 2007, 2011, and 2016. This document analyzes the PNW's projected loads and available generating resources in two parts: (1) the loads and resources of the Federal system, for which BPA is the mar

Interpersonal and economic resources.  

Science.gov (United States)

High population density and increased institutional specialization, which are relatively novel features of human society. have provided conditions for a more efficient exchange of universalistic resources, while decreasing the opportunity for exchanging particularistic ones. The parallel with physical environment is striking: in both cases technology has created new problems in the process of solving old ones. Whether it is natural resources or interpersonal resources, physical ecology or social ecology, recognizing and defining the new problem is the first step toward its solution. The importance of particularistic resources in solving problems of modern society has scarcely been recognized. Welfare institutions, for example, often require clients to lose status for the money they receive. This form of exchange deprives the client of a resource which is already scarce for him, thus further reducing his chances of autonomous performance as a resource exchanger in society. By ignoring the significance of particularistic resources for social functioning, we tend to see the solution of social problems exclusively in terms of a better distribution of economic resources. Improvement of education, for instance, is considered almost equivalent to allocating more money for schools. Truly money is one of the neighbors of information in the order, but the other one is status. Evidence to suggest that higher status improves educational achievement has, indeed, been repeatedly reported (26). The very mention of particularistic resources in social planning causes uneasiness and bafflement. The economist Levitan (27), for example, in reviewing the activities of VISTA (a program of the Office of Economic Opportunity), wonders how to evaluate goals such as dedication, involvement, and good feeling. The reluctance to include particularistic resources in social engineering will hopefully decrease as we improve techniques for their observation and measurement and as we begin to understand their rules of exchange and their relationship to other resources. The work described here may constitute a step in such a direction. The opportunity to progress more decisively toward a comprehensive picture of the state of resources in society is provided by the proposal to institute social indicators (28). Properly constructed they could supply much needed information about resource deficiencies that affect the health of society and could suggest. measures to overcome them. The purpose of this article has been to summarize some of the knowledge we already possess about interpersonal resources and to outline its application to certain problems of modern society. It has been shown that when resources are classified into six categories and plotted on a two-coordinate space a definite structural pattern emerges. The position of each resource class in the structure appears related to certain properties which in turn affect differentially the exchange of resources in an urban environment. The structural charateristics of resources provide a theoretical basis for the understanding and solution of social problems in modern culture. PMID:17808635

Reducing uranium resource uncertainty  

International Nuclear Information System (INIS)

This paper provides a conceptual framework for estimating the value of information to energy policy decisions and applies the methodology to assess the expected economic value of the U.S. Department of Energy's National Uranium Resource Evaluation (NURE) program. Uranium resource information is modelled by a likelihood function imbedded in a decision tree describing possible nuclear power development strategies. The results of the study show that the value of uranium resource information is potentially large compared to the cost of the NURE program. Attaining the large potential benefits will be difficult, however, since the information must be extraordinarily accurate to have a significant impact on the choice of nuclear policy options.

Asymptotic Resource Usage Bounds  

Digital Repository Infrastructure Vision for European Research (DRIVER)

When describing the resource usage of a program, it is usual to talk in asymptotic terms, such as the well-known “big O” notation, whereby we focus on the behaviour of the program for large input data and make a rough approximation by considering as equivalent programs whose resource usage grows at the same rate. Motivated by the existence of non-asymptotic resource usage analyzers, in this paper, we develop a novel transformation from a non-asymptotic cost function (which can be produced...

Electron/electron acoustic instability  

International Nuclear Information System (INIS)

The electron acoustic wave becomes a normal mode of an unmagnetized collisionless plasma in the presence of two electron components with similar densities, but strongly disparate temperatures. The characteristic frequency of this mode is the plasma frequency of the cooler electron component. If these two electron components have a relative drift speed several times the thermal speed of the cooler component, the electron/electron acoustic instability may arise. This paper describes the parametric dependences of the threshold drift speed and maximum growth rate of this instability, and compares these with the same properties of the electron/ion acoustic instability. Under the condition of zero current, the electron/ion acoustic instability typically has the lower threshold drift speed, so that observation of the electron/electron acoustic instability is a strong indication of the presence of an electrical current in the plasma

Uranium resources and requirements  

International Nuclear Information System (INIS)

Australia has about 19% of the reasonably assured resources of uranium in the Western World recoverable at costs of less than $A20 per kilogram, or about 9% of the resources (reasonably assured and estimated additional) recoverable at costs of less than $A30 per kilogram. Australia's potential for further discoveries of uranium is good. Nevertheless, if Australia did not export any of these resources it would probably have only a marginal effect on the development of nuclear power; other resources would be exploited earlier and prices would rise, but not sufficiently to make the costs of nuclear power unattractive. On the other hand, this policy could deny to Australia real benefits in foreign currency earnings, employment and national development. (author)

Unconventional natural gas resources  

Energy Technology Data Exchange (ETDEWEB)

Unconventional natural gas sources are subject to considerable amounts of research and controversy. The most often-mentioned unconventional sources are tight gas formations, coal seams, aquifers, and Devonian shales. However, there are other unconventional sources that also should be pointed out: methane hydrates, ultra-deep formations, and abiogenic gas. The chemical composition of gas from unconventional sources is essentially the same as natural gas from conventional resources which varies with the producing horizons. The major difference between the two is the nature of the reservoir. Gas production from the unconventional resources is technically more difficult, usually more expensive, and less predictable than conventional sources. This report describes in general the different unconventional natural gas resources. The difficulties in terms of production and the degree of success with producing the resources are discussed.

NATURAL RESOURCES ASSESSMENT  

International Nuclear Information System (INIS)

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 andO 2000c)

NASA Water Resources Program  

Science.gov (United States)

With increasing population pressure and water usage coupled with climate variability and change, water issues are being reported by numerous groups as the most critical environmental problems facing us in the 21st century. Competitive uses and the prevalence of river basins and aquifers that extend across boundaries engender political tensions between communities, stakeholders and countries. In addition to the numerous water availability issues, water quality related problems are seriously affecting human health and our environment. The potential crises and conflicts especially arise when water is competed among multiple uses. For example, urban areas, environmental and recreational uses, agriculture, and energy production compete for scarce resources, not only in the Western U.S. but throughout much of the U.S. and also in numerous parts of the world. Mitigating these conflicts and meeting water demands and needs requires using existing water resources more efficiently. The NASA Water Resources Program Element works to use NASA products and technology to address these critical water issues. The primary goal of the Water Resources is to facilitate application of NASA Earth science products as a routine use in integrated water resources management for the sustainable use of water. This also includes the extreme events of drought and floods and the adaptation to the impacts from climate change. NASA satellite and Earth system observations of water and related data provide a huge volume of valuable data in both near-real-time and extended back nearly 50 years about the Earth's land surface conditions such as precipitation, snow, soil moisture, water levels, land cover type, vegetation type, and health. NASA Water Resources Program works closely to use NASA and Earth science data with other U.S. government agencies, universities, and non-profit and private sector organizations both domestically and internationally. The NASA Water Resources Program organizes its projects under five functional themes. I) Streamflow and Flood Forecasting 2) Water Supply and Irrigation (includes evapotranspiration) 3) Drought 4) Water Quality 5) Climate and Water Resources.

Electronic cooling  

International Nuclear Information System (INIS)

The electronic cooling process which was devised aiming at the cooling of high energy antiprotons was never used for the original purpose. However, its excellent features attracted attention, and the cooler rings for the purpose of applying this method have been constructed in succession. So far the cooling of many ions including not only protons but also heavy ions and molecular ions was realized, and the experiments utilizing these have developed rapidly. In particular, by the experiment on atomic physics making cooling electron beam a target, the new region of research is opened. The recent technology of electronic cooling and the experiment on atoms and molecules making electrons the target are explained. The principle of cooling ion beam with electrons is described. To heighten electronic cooling efficiency and to lower ion temperature after cooling, as electron beam conditions, high density, low temperature, the agreement of the velocities of electrons and ions, the larger cross section of electron beam than that of ion beam, and uniform solenoid magnetic field are required. The electronic cooling equipment, the beam storage ring, the electronic cooling experiment and the electron target experiment are reported. (K.I.)

Resource revenues report  

Energy Technology Data Exchange (ETDEWEB)

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.

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.

Electron Tree  

DEFF Research Database (Denmark)

The photo shows a close-up of a Lichtenberg figure â?? popularly called an â??electron treeâ? â?? 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.

Transparent Electronics  

Directory of Open Access Journals (Sweden)

Full Text Available Transparent electronics is an emerging science and technology field concentrates on producing ‘invisible’ electronics circuit and optoelectronics devices. The application contains consumer electronics such as automobile windshield, transparent solar panel, transparent display and real time wearable display. In the conventional Si/III-V based electronics, the structure is based on semiconductor junction & transistor. However, the basic building material for transparent electronic devices which is to be transparent and in visible range is a true challenge! .Therefore to understand and implement such technology there are two scientific goals, to have a material which are optically transparent and electrically conductive and to implement an invisible circuitry. Development of such invisible transparent electronic devices needs expertise together from pure and applied science, material science, chemistry, physics &electronic science.

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.

Resource conservation management  

International Nuclear Information System (INIS)

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

This compilation represents the lectures of the Mannheim Symposium of the Gesellschaft fuer Wirtschafts- und Sozialwissenschaften held at Mannheim from 24th-26th September 1979. The papers of the 13 working groups were based on three complexes of questions, i.e. on analyses of the intertemporal allocation system, the role of markets and of governmental intervention concerning the allocation of resources, and, finally, international aspects of the allocation of resources. The topics of the meeting were provided by the oil crisis of 1973/74 and by the price increase for petroleum in 1979. The problems resulting herefrom were the long-term availability of natural resources, their utilization during the interim period, and the processes of adaptation to possible phenomena of shortage.

Natural resource damage assessment  

International Nuclear Information System (INIS)

The assessment and collection of natural resource damages from petroleum and chemical companies unfortunate enough to have injured publicly owned natural resources is perhaps the most rapidly expanding area of environmental liability. The idea of recovering for injury to publicly owned natural resources is an extension of traditional common law tort concepts under which a person who negligently injures another or his property is called upon to compensate the injured party. Normally, once liability has been established, it is a fairly straightforward matter to calculate the various elements of loss, such as the cost to repair or replace damaged property, or medical expenses, and lost income. More difficult questions, such as the amount to be awarded for pain and suffering or emotional distress, are left to the jury, although courts limit the circumstances in which the jury is permitted to award such damages

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.

Electron accelerator  

International Nuclear Information System (INIS)

The invention concerns an electron accelerator for exclusive production of x-rays, with an evacuated accelerator tube, with a target exposed to the electron beam and with an electron absorber topped downstream the target. With electron accelerators the penetration of the electrons through the electron outlet window of the accelerator tube sealing that window vacuum-tight keeps involving a loss of output. In order to avoid this the invention provides that the target borders immediately on the vacuum of the accelerator tube. In order to avoid local melting through of the target at high radiation outputs the target may be connected to a cooling system. The target may also be soldered on a metal plate with high thermal conductivity, which on its part seals gas-tight the accelerator tube on the radiation outlet side. Alternatively, the target surrounded by the flowing cooling medium may itself immediately seal gas-tight the outlet of the accelerator tube. (orig./RW)

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.

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

Lunar Water Resource Demonstration  

Science.gov (United States)

In cooperation with the Canadian Space Agency, the Northern Centre for Advanced Technology, Inc., the Carnegie-Mellon University, JPL, and NEPTEC, NASA has undertaken the In-Situ Resource Utilization (ISRU) project called RESOLVE. This project is a ground demonstration of a system that would be sent to explore permanently shadowed polar lunar craters, drill into the regolith, determine what volatiles are present, and quantify them in addition to recovering oxygen by hydrogen reduction. The Lunar Prospector has determined these craters contain enhanced hydrogen concentrations averaging about 0.1%. If the hydrogen is in the form of water, the water concentration would be around 1%, which would translate into billions of tons of water on the Moon, a tremendous resource. The Lunar Water Resource Demonstration (LWRD) is a part of RESOLVE designed to capture lunar water and hydrogen and quantify them as a backup to gas chromatography analysis. This presentation will briefly review the design of LWRD and some of the results of testing the subsystem. RESOLVE is to be integrated with the Scarab rover from CMIJ and the whole system demonstrated on Mauna Kea on Hawaii in November 2008. The implications of lunar water for Mars exploration are two-fold: 1) RESOLVE and LWRD could be used in a similar fashion on Mars to locate and quantify water resources, and 2) electrolysis of lunar water could provide large amounts of liquid oxygen in LEO, leading to lower costs for travel to Mars, in addition to being very useful at lunar outposts.

Unconventional natural gas resources  

Energy Technology Data Exchange (ETDEWEB)

The most-often mentioned sources of unconventional natural gas are tight gas formations, coal seams, aquifers, and Devonian shales. However, there are other unconventional sources such as methane hydrates, ultra-deep formations, and abiogenic gas. The chemical composition of gas from unconventional sources is essentially the same as natural gas from conventional resources which varies with the producing horizons. The major difference between the two is the nature of the reservoir. In unconventional sources the reservoir rock also may be the source bed, the permeability and porosity of the reservoir may be significantly less, the reservoir actually may be an aquifer, and/or the reservoir rock may not be the commonly accepted sandstone or carbonate formation. Gas production from the unconventional resources is technically more difficult, usually more expensive, and less predictable than conventional sources. This study describes the different unconventional natural gas resources. The difficulties in terms of production and the degree of success with producing the resources are discussed. 14 references.

Russian Arctic Petroleum Resources  

International Nuclear Information System (INIS)

The Arctic continental shelf is believed to be the area with the highest unexplored potential for oil and gas as well as for unconventional hydrocarbon resources such as gas hydrates. Despite a common view that the Arctic has plentiful of hydrocarbon resources, there are ongoing debates regarding the potential of this region as a future energy supply base. Driving forces for such discussions are geopolitics, environmental concern, assessment and delineation of Arctic resources, technology available for their successful development and the market demand for energy supply. The Russian part is recognized to be the largest among oil and gas resources owned by Arctic nations. However, scarce information and available geological data create uncertainty regarding a future role of the Russian Arctic as main base of energy supply in the second part of the 21. century. A further uncertainty is the pace at which production from northern areas including the Arctic will be brought on stream - either because of national policy, infrastructure development or investment by the state and the oil companies. These areas embrace those where development has already been started (Offshore Sakhalin, northern Timan Pechora) and those awaiting future involvement, like Barents and Pechora seas, East Siberia, Yamal, Kara Sea and Kamchatka. Offshore production levels are likely to be very important to Russia in mid and long terms, especially as most (if not all) production will go for export and, in the process, open doors to new markets. In this way, offshore production will introduce a new and very significant component to Russia's export strategy. However, active involvement of the Russian Arctic resources in the global energy supply process needs a detailed analysis and clear understanding of the market potential for Russian gas and oil (required volumes, time frame, transportations routes) and requires close attention of the government to the most important issues that should be in place, like national standards and guidelines for Arctic resources development, stable, transparent and predictable law as a necessary precondition for massive investments in exploration and production and, not least, active involvement of foreign companies in development of Arctic resources that could bring along with investments an indispensable competence and experience, available technology and Health, Safety and Environment (HSE) principles. Development of oil and gas fields in the arctic seas located few hundreds miles from shore is according to expert opinion the most challenging project in the world. Without international cooperation, coordination of all activities and use of modern and proven technologies for production of hydrocarbons, their transport, efficient safety and environmental protection tools the realization of such a project would be questionable.

Water - an inexhaustible resource?  

Science.gov (United States)

We have chosen to present the topic "Water", by illustrating problems that will give better opportunities for interdisciplinary work between Natural Science (Physics, Chemistry, Biology and Geology) teachers at first, but also English teachers and maybe others. Water is considered in general, in all its shapes and states. The question is not only about drinking water, but we would like to demonstrate that water can both be a fragile and short-lived resource in some ways, and an unlimited energy resource in others. Water exists on Earth in three states. It participates in a large number of chemical and physical processes (dissolution, dilution, biogeochemical cycles, repartition of heat in the oceans and the atmosphere, etc.), helping to maintain the homeostasis of the entire planet. It is linked to living beings, for which water is the major compound. The living beings essentially organized themselves into or around water, and this fact is also valid for human kind (energy, drinking, trade…). Water can also be a destroying agent for living beings (tsunamis, mud flows, collapse of electrical dams, pollution...) and for the solid earth (erosion, dissolution, fusion). I) Water, an essential resource for the human kind After having highlighted the disparities and geopolitical problems, the pupils will study the chemistry of water with its components and their origins (isotopes, water trip). Then the ways to make it drinkable will be presented (filtration, decantation, iceberg carrying…) II) From the origin of water... We could manage an activity where different groups put several hypotheses to the test, with the goal to understand the origin(s?) of water on Earth. Example: Isotopic signature of water showing its extraterrestrial origin.. Once done, we'll try to determine the origin of drinking water, as a fossil resource. Another use of isotopes will allow them to evaluate the drinking water age, to realize how precious it can be. III) Water as a sustainable energy resource Water is used to produce energy under different processes like ancient tamed energy such as water mills, locks or more recently tidal energy, marine current power, generators based on swell or osmotic gradients. The pupils will work in groups to present different techniques to the class. We could try to determine if all these energy resources could replace the actual major energy source in France: nuclear. Conclusion: Liquid water is probably the cradle of life. Since the birth of human kind, its history is closely linked to the presence of water: drinking, fishing, hygiene, and also transport or business is strictly depending on this resource. Described as a fragile and limited resource when it is used for human consumption, we realize that water is also an uneven resource of energy for the next generations. The challenge will then be to reconcile these different aspects: respecting this nourishing resource and preserving it from pollution, overexploitation or wasting, and at the same time, using water as energy for a world that has a growing population.

The electron  

International Nuclear Information System (INIS)

The stupendous successes of the Dirac equation and quantum electro-dynamics have established the electron as the best understood of the fundamental constituents of matter. Nevertheless, physicists agree that the electron still has secrets to reveal. Moreover, powerful new theoretical and experimental tools for probing those secrets have been sharpened during the last decade. This workshop was organized to bring theorists and experimentalists together to discuss their common goal of knowing the electron. Present state and future prospects for progress toward that goal are here described. The theoretical papers encompass a wide range of views on the electron. Several argue that the 'Zitter-bewegung' is more than a mathematical peculiarity of the Dirac equation, that it may well be a real physical phenomenon and worthy of serious study, theoretically and experimentally. Besides generating the electron spin and magnetic moment, the 'Zitterbewegung' may be a vital clue to electron structure and self-interaction. Some of the papers employ a radical new formulation of the Dirac theory which reveals a hidden geo-metric structure in the theory that supports a 'Zitterbewegung' inter-pretation. For the last half century the properties of electrons have been probed primarily by scattering experiments at ever higher energies. Recently, however, two powerful new experimental techniques have emerged capable of giving alternative experimental views of the electron. First, techniques for confining single electrons for long term study have led to the most accurate measurements of the electron magnetic moment. Second, the interaction of high intensity laser fields with atoms and electrons have revealed striking new phenomena such as multiphoton ionization. refs.; figs.; tabs

Efficient Resource Matching in Heterogeneous Grid Using Resource Vector  

CERN Document Server

In this paper, a method for efficient scheduling to obtain optimum job throughput in a distributed campus grid environment is presented; Traditional job schedulers determine job scheduling using user and job resource attributes. User attributes are related to current usage, historical usage, user priority and project access. Job resource attributes mainly comprise of soft requirements (compilers, libraries) and hard requirements like memory, storage and interconnect. A job scheduler dispatches jobs to a resource if a job's hard and soft requirements are met by a resource. In current scenario during execution of a job, if a resource becomes unavailable, schedulers are presented with limited options, namely re-queuing job or migrating job to a different resource. Both options are expensive in terms of data and compute time. These situations can be avoided, if the often ignored factor, availability time of a resource in a grid environment is considered. We propose resource rank approach, in which jobs are dispat...

Resources in NPD: An Investigation of Resource Capabilities  

Directory of Open Access Journals (Sweden)

Full Text Available In this paper we examine the role of resources in improving new product process outcomes. We propose amodel where resource flexibility and augmentation serve as mechanisms to identify and accumulate resourcesthat increase the firm’s ability to respond to opportunities and challenges in the new product developmentprocess. Important to the development of this resource base is the need to also leverage accumulated resources.Thus, the model is further developed to incorporate the role of resource leveraging as a moderator to theresource base and performance link. Using a cross-industry sample, a series of hypotheses are tested to evaluatethe moderating role of resource leveraging on the link between a firm’s resource base and its performance.Results suggest that resource flexibility and augmentation improves new product outcomes, and that resourceleveraging can lead to enhanced performance.

Electronic Structure  

Science.gov (United States)

This chapter is devoted to a discussion of the electronic structure of carbon and other nanotubes. It begins with a very general description of sp electronic states based on the tight-binding or Hückel approximation. This is sufficient to capture many basic electronic properties of single-walled nanotubes. This is followed by a more detailed analysis of the properties of carbon nanotubes, which is necessary when considering curvature effects, multi-walled nanotubes, bundles, etc. Although much less studied, other non-carbon nanotubes deserve also some attention: because of their ionic character boron nitride nanotubes and other mixed nanotubes offer in particular the opportunity of varying the electronic gap. This is described in a following section. The possibility of monitoring the electronic structure of carbon nanotubes as in the case of graphite, by intercalation and charge transfer are also investigated. Finally an extensive review on field emission is presented.

Kicking electrons  

CERN Document Server

The concept of dominant interaction hamiltonians is introduced and applied to classical planar electron-atom scattering. Each trajectory is governed in different time intervals by two variants of a separable approximate hamiltonian. Switching between them results in exchange of energy between the two electrons. A second mechanism condenses the electron-electron interaction to instants in time and leads to an exchange of energy and angular momentum among the two electrons in form of kicks. We calculate the approximate and full classical deflection functions and show that the latter can be interpreted in terms of the switching sequences of the approximate one. Finally, we demonstrate that the quantum results agree better with the approximate classical dynamical results than with the full ones.

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

Water resource development  

Energy Technology Data Exchange (ETDEWEB)

Federal and state governments both have strong constitutional claims and the political resources to influence the development and allocation of water resources. The authors define the roles and influence of each through three distinct periods of federal-state water policy: (1) the federally-dominated period of the 1960s; (2) a period of transition and rising state influence in the 1970s; and (3) an emerging period of state activity in the 1980s and 1990s. The process of sorting out which level has what power involves identifying which interests are actually being served. As water policy development and implementation move into the issues of water scarcity, growing demand, funding for water development, and state control and responsibility, the role of state government will continue to expand. 19 references.

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.

According to the National Oceanic and Atmospheric Adminstration (NOAA), El Nino is "a disruption of the ocean-atmosphere system in the tropical Pacific having important consequences for weather around the globe." It is caused by a change in trade wind patterns in the central and western Pacific ocean, and causes a large volume of ocean to be warmed (typically about 20 degrees of latitude by 90 degrees of longitude). It happens at irregular intervals and has global climatic consequences (regional flooding and droughts, in particular).

LHCb: Self managing experiment resources  

CERN Multimedia

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.

Due to the low funding levels registered in recent years in the NGO sector in Romania, many NGOs have faced a number of difficulties, some of them have ceased to carry on business. Financial position of the governmental sector is poor, especially for large organizations that are strictly dependent on foreign funds. For the good functioning of NGOs activity, it is requiring a constant concern for finacial fundraising. The article aims to present the diversity of financial resources of NGOs.

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)

Geothermal resource exploration  

Energy Technology Data Exchange (ETDEWEB)

Exploration for geothermal resources in the Basin and Range geomorphic province of the western United States is much akin to mineral resource exploration. In this region, potential geothermal resources are located at or near zones of intersection of normal faults, where fracture permeability permits deep circulation of meteoric water into high-temperature areas afforded by high regional heat flow. Exploration encompasses regional surveys, covering several thousand square kilometres, followed by more detailed studies of several hundred square kilometres to identify sites for deep drillholes. The most effective methods for regional exploration are geologic studies based on areal multispectral surveys, heat-flow drilling, chemical geothermometry of warm- and cold-water sources, and age-dating of rock. Detailed heat-flow-hydrologic surveys, gravity and active-seismic surveys, and geologic mapping are most effective in locating targets for deep confirmatory drilling. Geochemical-halo surveys may also be very effective in both regional and areal exploration. Results of geochemical, radiochemical, and geophysical surveys combine to furnish a comparison of long-term flow rates of geothermal systems, thereby permitting preliminary evaluation of the relative viability of the systems.

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.

Stem cells [electronic resource] : an insider's guide / Paul Knoepfler.  

Canada Institute for Scientific and Technical Information (Canada)

Stem Cells: An Insider's Guide is an exciting new book that takes readers inside the world of stem cells guided by international stem cell expert, Dr. Paul Knoepfler. Stem cells are catalyzing a revolution in medicine. The book also tackles the exciting and hotly debated area of stem cell treatments that are capturing the public's imagination. In the future they may also transform how we age and reproduce. However, there are serious risks and ethical challenges, too. The author's goal with this insider's guide is to give readers the information needed to distinguish between the ubiquitous hype and legitimate hope found throughout the stem cell world. The book answers the most common questions that people have about stem cells. Can stem cells help my family with a serious medical problem such as Alzheimer's, multiple sclerosis, or autism? Are such treatments safe? Can stem cells make me look younger or even literally stay physically young? These questions and many more are answered here. A number of ethical issues related to stem cells that spark debates are discussed, including risky treatments, cloning and embryonic stem cells. The author breaks new ground in a number of ways such as by suggesting reforms to the FDA, providing a new theory of aging based on stem cells, and including a revolutionary Stem Cell Patient Bill of Rights. More generally, the book is your guide to where the stem cell field will be in the near future as well as a thoughtful perspective on how stem cell therapies will ultimately change your life and our world.

The cellulose resource matrix.  

Science.gov (United States)

The emerging biobased economy is causing shifts from mineral fossil oil based resources towards renewable resources. Because of market mechanisms, current and new industries utilising renewable commodities, will attempt to secure their supply of resources. Cellulose is among these commodities, where large scale competition can be expected and already is observed for the traditional industries such as the paper industry. Cellulose and lignocellulosic raw materials (like wood and non-wood fibre crops) are being utilised in many industrial sectors. Due to the initiated transition towards biobased economy, these raw materials are intensively investigated also for new applications such as 2nd generation biofuels and 'green' chemicals and materials production (Clark, 2007; Lange, 2007; Petrus & Noordermeer, 2006; Ragauskas et al., 2006; Regalbuto, 2009). As lignocellulosic raw materials are available in variable quantities and qualities, unnecessary competition can be avoided via the choice of suitable raw materials for a target application. For example, utilisation of cellulose as carbohydrate source for ethanol production (Kabir Kazi et al., 2010) avoids the discussed competition with easier digestible carbohydrates (sugars, starch) deprived from the food supply chain. Also for cellulose use as a biopolymer several different competing markets can be distinguished. It is clear that these applications and markets will be influenced by large volume shifts. The world will have to reckon with the increase of competition and feedstock shortage (land use/biodiversity) (van Dam, de Klerk-Engels, Struik, & Rabbinge, 2005). It is of interest - in the context of sustainable development of the bioeconomy - to categorize the already available and emerging lignocellulosic resources in a matrix structure. When composing such "cellulose resource matrix" attention should be given to the quality aspects as well as to the available quantities and practical possibilities of processing the feedstock and the performance in the end-application. The cellulose resource matrix should become a practical tool for stakeholders to make choices regarding raw materials, process or market. Although there is a vast amount of scientific and economic information available on cellulose and lignocellulosic resources, the accessibility for the interested layman or entrepreneur is very difficult and the relevance of the numerous details in the larger context is limited. Translation of science to practical accessible information with modern data management and data integration tools is a challenge. Therefore, a detailed matrix structure was composed in which the different elements or entries of the matrix were identified and a tentative rough set up was made. The inventory includes current commodities and new cellulose containing and raw materials as well as exotic sources and specialties. Important chemical and physical properties of the different raw materials were identified for the use in processes and products. When available, the market data such as price and availability were recorded. Established and innovative cellulose extraction and refining processes were reviewed. The demands on the raw material for suitable processing were collected. Processing parameters known to affect the cellulose properties were listed. Current and expected emerging markets were surveyed as well as their different demands on cellulose raw materials and processes. The setting up of the cellulose matrix as a practical tool requires two steps. Firstly, the reduction of the needed data by clustering of the characteristics of raw materials, processes and markets and secondly, the building of a database that can provide the answers to the questions from stakeholders with an indicative character. This paper describes the steps taken to achieve the defined clusters of most relevant and characteristic properties. These data can be expanded where required. More detailed specification can be obtained from the background literature and handbooks. Where gaps of information are ident

Accumulation of astaxanthin and lutein in Chlorella zofingiensis (Chlorophyta).  

Science.gov (United States)

When grown photoautotrophically, Chlorella zofingiensis strain CCAP 211/14 accumulates a significant amount of valuable carotenoids, namely astaxanthin and lutein, of increasing demand for use as feed additives in fish and poultry farming, as colorants in food, and in health care products. Under standard batch-culture conditions, this microalgal strain exhibits high values of both growth rate (about 0.04 h(-1)) and standing cell population (over 10(11) cells l(-1), or 7 g dry weight l(-1)). Lutein, in a free (unesterified) form, was the prevalent carotenoid during early stages of cultivation (over 0.3 pg cell(-1), equal to 4 mg g(-1) dry weight, or 20 mg l(-1) culture), whereas esterified astaxanthin accumulated progressively, to reach a maximum (over 0.1 pg cell(-1), equal to 1.5 mg g(-1) dry weight, or 15 mg l(-1) culture) in the late stationary phase. A differential response of lutein and astaxanthin accumulation was also recorded with regard to the action of some environmental and nutritional factors. C. zofingiensis CCAP 211/14 represents a unique model system for analyzing the differential regulation of the levels of primary (lutein) and secondary (astaxanthin) carotenoids. Relevant also from the biotechnological viewpoint, this photosynthetic organism, with outstanding attributes for fast photosynthetic growth and carotenoid accumulation, might prove most valuable for its application to the mass production of either or both lutein and astaxanthin.

Full Text Available SciELO Brazil | Language: English Abstract in english In this paper, we summarize the diversity of Polyphysaceae species in Todos os Santos Bay, in the state of Bahia, Brazil. On the basis of ten years of collections and the analysis of herbarium material, six species have been recorded for the area: Acetabularia caliculus J.V.Lamour. in Quoy & Gaimard [...] ; A. crenulata J.V.Lamour.; A. schenckii Möbius; Parvocaulis myriosporus (Joly & Cord.-Mar.) C.W.N.Moura & J.C.De Andrade comb. nov.; P. pusillus (M.Howe) Berger et al.; and P. parvulus (Solms) S. Berger et al. The last has a distribution extending to the southern Atlantic Ocean. Acetabularia myriospora was transferred to Parvocaulis (as P. myriosporus) on the basis of its short corrugated peduncles and lack of a lower corona in the gametangial ray discs, which are diagnostic characters of this genus. In Todos os Santos Bay, Acetabularia species are more widely distributed than are Parvocaulis species, which are currently restricted to Itaparica Island. The most common taxa were A. caliculus and A. schenckii, which were collected from the majority of the study sites. This paper provides detailed descriptions of the morphology, reproductive aspects and geographic distributions of the algae, as well as discussing the taxa studied.

Fermionic Resources for Quantum Teleportation  

Science.gov (United States)

The measurement-based quantum computing (MBQC) model requires the creation of a massively entangled ``resource state,'' on which computation proceeds via single-qubit measurements. Although 2D resource states are believed necessary for universal MBQC, 1D states can serve as resources for certain tasks as well, such as quantum teleportation. One possible route to a resource state is to cool a gapped, two-body system whose ground state encodes the resource. I will discuss our recent work in this area, in which we investigate candidate fermionic systems using the Density Matrix Renormalization Group method and the Matrix Product States description of highly entangled 1D states.

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.

NEWS: TRUMP resources  

Science.gov (United States)

Support for astronomy in A-level physics aslogo Help is at hand for teachers and students choosing astronomy as part of A-level physics. The Teaching Resources Unit for Modern Physics (TRUMP) has produced a resource package covering all the astronomical options in the Edexcel, OCR and AQA (NEAB) syllabuses. The forerunner to TRUMP was the project that produced the highly successful Particle Physics Pack, sponsored by the Institute of Physics, which was instrumental in introducing particle physics into A-level syllabuses. The TRUMP Astrophysics Resource Package fills a gap between the colourful stimulus of popular materials on the one hand, and professional texts on the other. But this is not just another A-level textbook; the six-part resource pack has a similar structure and purpose to the Particle Physics Pack. It provides over 400 pages of comprehensive information for teachers, building on their existing subject knowledge and bringing them up to date as well as giving suggestions for teaching and notes on syllabus coverage. The package includes nearly 40 photocopiable sheets for students. The emphasis is on the physics that underpins the astronomy. There are details of student activities requiring no specialist equipment beyond that normally found in A-level labs, exercises using authentic data, and plenty of questions (all with worked solutions). The development of the TRUMP Astrophysics Package was funded by the Nuffield Foundation, the Particle Physics and Astronomy Research Council, the Institute of Physics and York University. The package is available by mail order, price £48 (inc. UK p&p) from the TRUMP Project, Science Education Group, University of York, Heslington, York YO10 5DD. Some parts may be purchased separately; for details contact the project's director, Elizabeth Swinbank (tel: 01904 434537, fax: 01904 434078, e-mail: es14@york.ac.uk) or consult the web page www.york.ac.uk/org/seg/trump. The BaBar experiment balogo In the spring of 1999, scientists began to collect data from the BaBar experiment - an international collaboration involving the UK, several other European countries and the USA. The experiment is designed to throw light on the puzzling question of why there is so little antimatter in the universe and so much matter. The TRUMP BaBar resource package brings the mystery of antimatter into schools. There are notes and colourful posters on the physics of BaBar, and photocopiable sheets supporting student activities. These include explorations of symmetry, templates for making a scale model of the BaBar detector, and a web-based research project. The pack is designed mainly for A-level physics (particularly those courses that include some particle physics) but parts also relate to GCSE science, Scottish Higher physics and Standard physics. The BaBar resource package is available free from the Particle Physics and Astronomy Research Council, which fully funded its development and production.

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.

Nonconventional natural gas resources  

Energy Technology Data Exchange (ETDEWEB)

It is concluded that it is impossible at this time to forecast the volume of natural gas dissolved in water that can be economically recovered. The investigation to southern Louisiana, both onshore and offshore was confined. Estimates of the dissolved methane content are based upon information on temperatures, pressures, sandstone thicknesses, sandstone porosities, salinity, and the solubility of methane. The salinity of waters encountered in wells was estimated from wireline logs, and in turn used to reduce the estimated content of dissolved gas. The reductions range from 51 to 61 percent of the solubility of methane in fresh water. The assessment does not include gas dissolved in water contained in shale beds. A series of maps display the information used in the computation. Methane solubility values were multiplied by porosity--feet values for each 1000-foot interval. The total dissolved methane in the resource base is estimated to be 6,143 trillion cubic feet (Tcf); assumptions on the effect of salinity reduce this to 3,264 Tcf. This figure does not include methane beneath the Texas coast. Very preliminary estimates of the recoverable proportion of dissolved gas in the highly ''geopressured'' zones range from 1 to over 20 percent. Not all of the resource base estimates of 3,264 Tcf occurs in the highly geopressured zone, and the proportions individually allocatable within the resource base to the highly ''geopressured'' zone, to the intermediate-pressure zone, and to the normal or ''hydropressure'' zone cannotbe estimated readily. The environmental aspects of recovery of dissolved gas are also presented. The review is necessarily generalized, since it could not be based on actual experience. The problems include subsidence of land surface and possibly increased seismic activity. Fluid withdrawal might result in subsidence of the land surface, as well as activation of growth faults, with adjustments extending to the surface.

Digital Repository Infrastructure Vision for European Research (DRIVER)

This paper presents a model of financial resource curse, i.e. episodes of abundant access to foreign capital coupled with weak productivity growth. We study a two-sector, tradable and non-tradable, small open economy. The tradable sector is the engine of growth, and productivity growth is increasing in the amount of labor employed by firms in the tradable sector. A period of large capital inflows, triggered by a fall in the interest rate, is associated with a consumption boom. While the incre...

Taxation of exhaustible resources  

Energy Technology Data Exchange (ETDEWEB)

The efficiency and equity effects of unit, yield, property, and windfall profits taxes upon nonrenewable resources are compared. The yield tax is the most efficient, and unit and property taxes are the least efficient of current taxes. If the base price of the windfall profits tax is set close to extraction cost, the windfall profits tax can be even more efficient than the yield tax. All the tax burdens fall primarily upon owners. In fact, with the property and windfall profits taxes, consumers can even be made better off. 4 references, 7 tables.

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.

Safeguards resource management  

International Nuclear Information System (INIS)

Protecting nuclear materials is a challenging problem for facility managers. To counter the broad spectrum of potential threats, facility managers rely on diverse safeguards measures, including elements of physical protection, material control and accountability, and human reliability programs. Deciding how to upgrade safeguards systems involves difficult tradeoffs between increased protection and the costs and operational impact of protection measures. Effective allocation of safeguards and security resources requires a prioritization of system upgrades based on a relative measure of upgrade benefits to upgrade costs. Analytical tools are needed to help safeguards managers measure the relative benefits and costs and allocate their limited resources to achieve balanced, cost-effective protection against the full spectrum of threats. This paper presents a conceptual approach and quantitative model that have been developed by Lawrence Livermore National Laboratory to aid safeguards managers. The model is in the preliminary stages of implementation, and an effort is ongoing to make the approach and quantitative model available for general use. The model, which is designed to complement existing nuclear safeguards evaluation tools, incorporates a variety of factors and integrates information on the likelihood of potential threats, safeguards capabilities to defeat threats, and the relative consequences if safeguards fail. The model uses this information to provide an overall measure for comparing safeguards upgrade projects at a facility

Most of the site's sections can be reached from the home page, and deal with such topics as assessment in higher education, news, and recent publications that feature research on higher education. Another helpful feature is a collection of links to the syllabi for courses at the college and graduate level that address the topic of higher education. The history of higher education is particularly helpful, as it contains a number of primary documents including the text of the GI Bill, the Morrill Land Grant Acts, some rather trenchant commentaries from John Henry Newman, and Thorstein Veblen's scathing critique of American higher education published in 1918. The site also has a section devoted to job resources in higher education, and is completed with information about the reference work, "Higher Education in the United States: An Encyclopedia," which is co-edited by Mr. Forest and Kevin Kinser of SUNY-Albany.

Sharing resources@CERN  

CERN Multimedia

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...

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.

Electronic cigarette (e-cigarettes) belongs to the "ENDS (Electronic Nicotine Delivery Systems), ie systems that deliver nicotine electronically. Extract of tobacco does not burn, just warm. Vapors may or may not contain nicotine. E-cigarettes are also available with different flavors. They don't produce a classic smoke. There is a large variability of these products. It seems that the initial negative position has to be reconsidered. Although there has been demonstrated trace amounts of several toxic substances in the vapor, the risk compared to traditional smoking is minimal. Moreover, lately it was shown that they can really contribute to smoking quitting. The legislative framework varies considerably, from the prohibition on sales to the recommended assistance in quitting. In the CR they are included according to the Act 379/2005 in 2009 among the tobacco products. PMID:22679688

Uranium resources of Niger  

International Nuclear Information System (INIS)

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, Terzemaz
