Investigations of cell morphology and reproduction in Macrochloris radiosa Ettl & Gärtner (Stephano-sphaerinia, Chlorophyta) by light- and WUDQVPLVVLRQ electron microscopy  

Science.gov (United States)

Cell division and reproduction of a cultivated strain of Macrochloris radiosa (Stephanosphaerinia clade) were studied by light- and transmission electron microscopy. Multinucleate cells were frequently observed allowing description of the cell structure and details of the reproduction process. Nuclear staining revealed the position of the multiple polymorphic nuclei between the chloroplast lobes. Ultrastructure of coenocytic cells showed no signs of cleavage of the protoplast in the cytoplasm, although basal bodies were already present within the multinucleate cells. In the further course of the reproduction, biflagellate zoospores were developed that retained their flagella during sporulation. Zoospores were subsequently released from the sporangia.

Electronic neural network for dynamic resource allocation  

Science.gov (United States)

A VLSI implementable neural network architecture for dynamic assignment is presented. The resource allocation problems involve assigning members of one set (e.g. resources) to those of another (e.g. consumers) such that the global 'cost' of the associations is minimized. The network consists of a matrix of sigmoidal processing elements (neurons), where the rows of the matrix represent resources and columns represent consumers. Unlike previous neural implementations, however, association costs are applied directly to the neurons, reducing connectivity of the network to VLSI-compatible 0 (number of neurons). Each row (and column) has an additional neuron associated with it to independently oversee activations of all the neurons in each row (and each column), providing a programmable 'k-winner-take-all' function. This function simultaneously enforces blocking (excitatory/inhibitory) constraints during convergence to control the number of active elements in each row and column within desired boundary conditions. Simulations show that the network, when implemented in fully parallel VLSI hardware, offers optimal (or near-optimal) solutions within only a fraction of a millisecond, for problems up to 128 resources and 128 consumers, orders of magnitude faster than conventional computing or heuristic search methods.

Why and How to Measure the Use of Electronic Resources  

Directory of Open Access Journals (Sweden)

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

The Study of Analytical Model of Library Electronic Resources Usage-A Case of Medical Electronic Resources  

Directory of Open Access Journals (Sweden)

Full Text Available With the advents of internet, the importance of electronic resources is growing. Due to the increasing expensiveness of electronic resources, university libraries normally received budgets from parent institutions annually. They necessarily applied effective and systematic methods for decision making in electronic resources purchase or re-subscription. However, there are some difficulties in practices: First of all, libraries are unable to receive user records; second, the COUNTER statistics does not include details about users and their affiliation. As a result, one cannot conduct advanced user analysis based on the usage of users, institutions, and departments. To overcome the difficulties, this study presents a feasible model to analyze electronic resource usage effectively and flexibly. We set up a proxy server to collect actual usage raw data. By analyzing items in internet browsing records, associated with original library automatic system, this study aims at exploring how to use effective ways to analyze big data of website log data. We also propose the process of how original data to be transformed, cleared, integrated, and demonstrated. This study adopted a medical university library and its subscription of medical electronic resources as a case. Our data analysis includes (1 year of subscription,(2 title of journal, (3 affiliation, (4 subjects, and (5 specific journal requirements, etc. The findings of the study are contributed to obtain further understanding in policy making and user behavior analysis. The integrated data provides multiple applications in informatics research, information behavior, bibliomining, presenting diverse views and extended issues for further discussion.

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.

ASIL Guide to Electronic Resources for International Law  

Science.gov (United States)

The study and practice of international law can be a tough area to get a handle on, and with numerous online resources available for both areas, it can be difficult to separate the wheat from the chaff. Since 1997, The American Society of International Law (ASIL) has been continuously updating and revising their Guide to Electronic Resources for International Law, under the able direction of Marci Hoffman and Jill Watson. Within each of its eight primary sections, users can read about various high-quality online resources for each topical area (such as international organizations and human rights), and then read brief summaries of what each online resource features in terms of its content and scope. As might be expected, the site also contains information on relevant and helpful weblogs that deal with international law.

Journals, Data and Abstracts Make an Integrated Electronic Resource  

Science.gov (United States)

Astronomy now has an integrated, Web-based information resource for research papers, data and bibliographic information. The major scholarly research journals, a comprehensive abstract service and the astronomical data centers are now linked together to provide an information resource which is not available to most other scientific disciplines. As of January, 1997, the Astrophysical Journal joins the ApJ Letters on the Web. Astronomy and Astrophysics Supplements now has a page image version. Elsevier's electronic journal New Astronomy has recently made its appearance. Over forty percent of the new peer-reviewed, astronomical literature is now available electronically. The main Astronomy and Astrophysics journal, the Astronomical Journal and others will be available by 1998, at which point ninety percent of the literature will be available electronically, a figure not approached by any other scientific discipline. With so many different sources, one of the challenges has been to integrate the on-line, peer-reviewed literature into a resource which serves the astronomical community in a unified and coherent manner. Following the lead of the AAS, the major publishers have chosen to rely upon the NASA-supported Astrophysics Data System (ADS) and the astronomical data centers to provide the means by which the various separate journals can interoperate. The data centers and the ADS have developed unique identification codes for journal articles. By adopting the existing standard "bibcodes" and integrating them into their WWW links, each of the major astronomical journals are able to link to the abstracts of most of the referenced articles. Since the ADS also serves as an on-line repository for page images of the past twenty years of the major astronomical journals, the full text of many of the referenced articles are available, too. The articles in the ADS have recently been linked through their references, both forward and backward in time. With the "bibcode" providing the linking framework, papers in the electronic research journals, data and abstracts will be incorporated into the system in a routine manner. The astronomical community now has an ever-growing, operational integrated information system which fulfills today, the dream of the digital library. It remains to be seen how this electronic resource will affect the progress of research.

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.

Electronic Safety Resource Tools – Supporting Hydrogen and Fuel Cell Commercialization  

Energy Technology Data Exchange (ETDEWEB)

The Pacific Northwest National Laboratory (PNNL) Hydrogen Safety Program conducted a planning session in Los Angeles, CA on April 1, 2014 to consider what electronic safety tools would benefit the next phase of hydrogen and fuel cell commercialization. A diverse, 20-person team led by an experienced facilitator considered the question as it applied to the eight most relevant user groups. The results and subsequent evaluation activities revealed several possible resource tools that could greatly benefit users. The tool identified as having the greatest potential for impact is a hydrogen safety portal, which can be the central location for integrating and disseminating safety information (including most of the tools identified in this report). Such a tool can provide credible and reliable information from a trustworthy source. Other impactful tools identified include a codes and standards wizard to guide users through a series of questions relating to application and specific features of the requirements; a scenario-based virtual reality training for first responders; peer networking tools to bring users from focused groups together to discuss and collaborate on hydrogen safety issues; and a focused tool for training inspectors. Table ES.1 provides results of the planning session, including proposed new tools and changes to existing tools.

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.

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)

?????????????????????? A Study of Demands Analysis and Marketing Strategy of Electronic Resources in University Library  

Directory of Open Access Journals (Sweden)

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

Electronic textbooks as a professional resource after dental school.  

Science.gov (United States)

In two previous studies of dental students' attitudes about the VitalSource Bookshelf, a digital library of dental textbooks, students expressed negative opinions about owning and reading electronic textbooks. With the assumption that dentists would find the digital textbooks useful for patient care, the authors surveyed recent graduates to determine if their attitude toward the VitalSource Bookshelf had changed. A brief survey was sent to 119 alumni from the classes of 2009 and 2010 of one U.S. dental school. Forty-seven (39.5 percent) completed the questionnaire. Eighteen respondents (48.3 percent) reported using the e-textbooks often or sometimes. The twenty-nine dentists who said they have not used the collection since graduation reported preferring print books or other online sources or having technical problems when downloading the books to a new computer. Only five respondents selected the VitalSource Bookshelf as a preferred source of professional information. Most of the respondents reported preferring to consult colleagues (37.8 percent), the Internet (20 percent), or hardcopy books (17.8 percent) for information. When asked in an open-ended question to state their opinion of the Bookshelf, nineteen (42.2 percent) responded positively, but almost one-third of these only liked the search feature. Six respondents reported that they never use the program. Twenty-two said they have had technical problems with the Bookshelf, including fifteen who have not been able to install it on a new computer. Many of them said they have not followed up with either the dental school or VitalSource support services to overcome this problem. Our study suggests that dentists, similar to dental students, dislike reading electronic textbooks, even with the advantage of searching a topic across more than sixty dental titles. PMID:22550109

Full Text Available SciELO Brazil | Language: English Abstract in portuguese 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 enzimátic [...] as, 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. Abstract in english 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, a [...] nd 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.

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

Directory of Open Access Journals (Sweden)

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

Molecular identification and culture observation on Acrochaete leptochaete (Chaetophoraceae, Chlorophyta) from China  

Science.gov (United States)

Acrochaete leptochaete (Huber) Nielsen (Chaetophoraceae, Chlorophyta) was isolated from the macroalgae Chaetomorpha collected from intertidal pools in Rongcheng, Shandong, China. 18S rDNA combined with ITS regions were used to ascertain the morphological identification of the isolated material. Based on the unialgal culture, asexual reproduction and growth characteristics of A. leptochaete were investigated over wide ranges of temperature and irradiance. Results revealed that asexual reproduction of A. leptochaete could be realized by biflagellate zoospores. The zoospores germinated directly to give self-replicating generations. Zoospore germination was bipolar. A temperature range from 13-21°C and a lower irradiance of 36 ?mol/(m2·s) were most favorable for the growth of A. leptochaete. Thallus organization, an important taxonomic criterion for the genus Acrochaete, was affected markedly by temperature and irradiance. Our results extend the knowledge about the species' general biology and its morphological plasticity. For classification and identification of a simple microphytic algae like A. leptochaete, which are traditionally placed in the class Chaetophoraceae, we propose that molecular tools associated with culture observations are applied.

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 wpes 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.

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

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

Science.gov (United States)

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.

Caring for children and adolescents with epilepsy: creating an innovative electronic educational resource.  

Science.gov (United States)

The majority of children and adolescents with epilepsy are managed in the community setting by general paediatricians. However, there is a paucity of practical, relevant information and standardised management documents assisting paediatricians. In the era of sub-specialisation, an electronic educational resource developed by specialists in epilepsy and paediatrics enhances the interface between tertiary and secondary/primary care. We aimed to create a website (www.pennsw.com.au) designed to optimise the care of all children and adolescents living with epilepsy and to assess its clinical usefulness. The site provides clinicians and families an aligned resource, including key information on epilepsy syndromes, medication usage and adverse effects, safety (sleep deprivation, water sports), driving, pregnancy, psychosocial impact of epilepsy and coping skills. General paediatricians and carers completed a questionnaire, utilising rating scales and open ended questions, to evaluate design, content and clinical usefulness. Forty-nine general paediatricians with a median 12 years of paediatric practice participated. Thirty-two carers participated. Epilepsy syndrome was focal in 59% of the children and generalised in 41%. The majority of participants (paediatricians: 84-100%, families: 69-100%) rated the website as well designed, practical, informative and clinically useful. General paediatricians considered the "Medication" pages and "Epilepsy Management Documents" as practically useful. Carers recorded the "Family Resources", seizure recording documents, the support information on mental health, and the "Coping with Epilepsy" segment as most informative. General paediatricians and carers highly valued the website, reflected by 120,000 page views in 12 months since its launch. PMID:24906210

Full Text Available Los componentes de la flora béntica, y mediciones de partes vegetativas y reproductivas de Batophora oerstedii y B. occidentalis (Chlorophyta se registraron en cinco sitios de la costa Oeste de la Bahía de Chetumal, donde se ha registrado la existencia de un gradiente de contaminación orgánica. La colecta de flora se realizó en mayo y Octubre de 1999, meses incluidos en las épocas climáticas de secas y lluvias, respectivamente. Se registraron 40 taxa de vegetación béntica, de los cuales 11 representan nuevos registros para la Bahía de Chetumal, y 6 para el Caribe Mexicano. Especies de Enteromorpha estuvieron presentes en ambientes ricos en materia orgánica, tanto de origen urbano, como natural. En los desagües de la Bahía de Chetumal existen especies indicadoras de contaminación, pero la ausencia de Batophora spp., dominante en esta laguna costera. Los caracteres morfológicos de B. occidentalis y B. oerstedii a lo largo de los cinco sitios de muestreo no reflejaron la presencia de contaminantes. Ambas especies presentaron diferencias significativas en su largo y ancho de gametóforos, y en el diámetro de gametangios. Las diferencias en estrategias reproductivas probablemente ayudan a que B. oerstedii y B. occidentalis puedan coexistir cercanamente en la Bahía de Chetumal.Benthic flora and reproduction of Batophora spp. algae (Chlorophyta: Dasycladaceae in a polluted coastal lagoon (Chetumal Bay, Mexico. The benthic flora, and the vegetative and reproductive characters of the algae Batophora oerstedii and B. occidentalis (Chlorophyta were recorded from five sites of Chetumal Bay, Quintana Roo, Mexico. A sewage gradient has been reported along those sites. Plants were sampled in May and October 1999, which corresponded to dry and rainy seasons, respectively. Forty taxa were found, 11 are new records for the Chetumal Bay, and 6 are new records for the Mexican Caribbean. Enteromorpha species were present in sites known as rich in organic matter (both from anthropogenic and natural sources. Batophora spp. is the dominant algae in all Chetumal Bay. However, it was absent next to sewage outfalls. The morphological characters of B. oerstedii and B. occidentalis did not change significantly along the sites reported as polluted. The length and width of gametophores, as well as the diameter of the gametangia were clearly different for both species. Different reproductive strategies may help B. oerstedii and B. ccidentalis to closely coexist in the Chetumal Bay. Rev. Biol. Trop. 54(2: 341-355. Epub 2006 Jun 01.

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.

Use and Cost of Electronic Resources in Central Library of Ferdowsi University Based on E-metrics  

Directory of Open Access Journals (Sweden)

Full Text Available The purpose of this study was to investigate the usage of electronic journals in Ferdowsi University, Iran based on e-metrics. The paper also aimed to emphasize the analysis of cost-benefit and the correlation between the journal impact factors and the usage data. In this study experiences of Ferdowsi University library on licensing and usage of electronic resources was evaluated by providing a cost-benefit analysis based on the cost and usage statistics of electronic resources. Vendor-provided data were also compared with local usage data. The usage data were collected by tracking web-based access locally, and by collecting vender-provided usage data. The data sources were one-year of vendor-supplied e-resource usage data such as Ebsco, Elsevier, Proquest, Emerald, Oxford and Springer and local usage data collected from the Ferdowsi university web server. The study found that actual usage values differ for vendor-provided data and local usage data. Elsevier has got the highest usage degree in searches, sessions and downloads. Statistics also showed that a small number of journals satisfy significant amount of use while the majority of journals were used less frequent and some were never used at all. The users preferred the PDF rather than HTML format. The data in subject profile suggested that the provided e-resources were best suited to certain subjects. There was no correlation between IF and electronic journal use. Monitoring the usage of e-resources gained increasing importance for acquisition policy and budget decisions. The article provided information about local metrics for the six surveyed vendors/publishers, e.g. usage trends, requests per package, cost per use as related to the scientific specialty of the university.

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

Directory of Open Access Journals (Sweden)

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

Understanding intention to use electronic information resources: A theoretical extension of the technology acceptance model (TAM).  

Science.gov (United States)

This study extended the Technology Acceptance Model (TAM) by examining the roles of two aspects of e-resource characteristics, namely, information quality and system quality, in predicting public health students' intention to use e-resources for completing research paper assignments. Both focus groups and a questionnaire were used to collect data. Descriptive analysis, data screening, and Structural Equation Modeling (SEM) techniques were used for data analysis. The study found that perceived usefulness played a major role in determining students' intention to use e-resources. Perceived usefulness and perceived ease of use fully mediated the impact that information quality and system quality had on behavior intention. The research model enriches the existing technology acceptance literature by extending TAM. Representing two aspects of e-resource characteristics provides greater explanatory information for diagnosing problems of system design, development, and implementation. PMID:18999300

Prevalence and mechanism of polyunsaturated aldehydes production in the green tide forming macroalgal genus Ulva (Ulvales, Chlorophyta).  

Science.gov (United States)

Lipoxygenase/hydroperoxide lyase mediated transformations convert polyunsaturated fatty acids into various oxylipins. First, lipoxygenases catalyze fatty acid oxidation to fatty acid hydroperoxides. Subsequently, breakdown reactions result in a wide array of metabolites with multiple physiological and ecological functions. These fatty acid transformations are highly diverse in marine algae and play a crucial rule in e.g., signaling, chemical defense, and stress response often mediated through polyunsaturated aldehydes (PUAs). In this study, green tide-forming macroalgae of the genius Ulva (Chlorophyta) were collected at various sampling sites in the lagoon of the Ria Formosa (Portugal) and were surveyed for PUAs. We demonstrated that sea-lettuce like but not tube-like morphotypes produce elevated amounts of volatile C10-polyunsaturated aldehydes (2,4,7-decatrienal and 2,4-decadienal) upon tissue damage. Moreover, morphogenetic and phylogenetic analyses of the collected Ulva species revealed chemotaxonomic significance of the perspective biosynthetic pathways. The aldehydes are derived from omega-3 and omega-6 polyunsaturated fatty acids (PUFA) with 20 or 18 carbon atoms including eicosapentaenoic acid (C20:5 n-3), arachidonic acid (C20:4 n-6), stearidonic acid (C18:4 n-3), and ?-linolenic acid (C18:3 n-6). We present first evidences that lipoxygenase-mediated (11-LOX and 9-LOX) eicosanoid and octadecanoid pathways catalyze the transformation of C20- and C18-polyunsaturated fatty acids into PUAs and concomitantly into short chain hydroxylated fatty acids.

The appearance of Ulva laetevirens (Ulvophyceae, Chlorophyta) in the northeast coast of the United States of America  

Science.gov (United States)

Introduced species may outcompete or hybridize with native species, resulting in the loss of native biodiversity or even alteration of ecosystem processes. In this study, we reported an alien distromatic Ulva species, which was found in an embayment (Holly Pond) connected with Long Island Sound, USA. The morphological and anatomical observations in combination with molecular data were used for its identification to species. Anatomy of collected specimens showed that the cell shape in rhizoidal and basal regions was round and the marginal teeth along the basal and median region were not found. These characteristics were primarily identical to the diagnostic characteristics of Ulva laetevirens Areschoug (Chlorophyta). The plastid-encoding tufA and nucleusencoding ITS1 were used for its molecular identification. Phylogenetic analysis for the tufA gene placed the specimens from Holly Pond in a well-supported clade along with published sequences of U. laetevirens identified early without any sequence divergence. In ITS tree, the sample also formed well-supported clades with the sequences of U. laetevirens with an estimated sequence divergence among the taxa in these clades as low as 1%. These findings confirmed the morpho-anatomical conclusion. Native to Australia, this species was reported in several countries along the Mediterranean coast after the late of 1990s. This is the first time that U. laetevirens is found in the northeast coast of United States and the second record for Atlantic North America.

Data resource profile: cardiovascular disease research using linked bespoke studies and electronic health records (CALIBER).  

Science.gov (United States)

The goal of cardiovascular disease (CVD) research using linked bespoke studies and electronic health records (CALIBER) is to provide evidence to inform health care and public health policy for CVDs across different stages of translation, from discovery, through evaluation in trials to implementation, where linkages to electronic health records provide new scientific opportunities. The initial approach of the CALIBER programme is characterized as follows: (i) Linkages of multiple electronic heath record sources: examples include linkages between the longitudinal primary care data from the Clinical Practice Research Datalink, the national registry of acute coronary syndromes (Myocardial Ischaemia National Audit Project), hospitalization and procedure data from Hospital Episode Statistics and cause-specific mortality and social deprivation data from the Office of National Statistics. Current cohort analyses involve a million people in initially healthy populations and disease registries with ?10(5) patients. (ii) Linkages of bespoke investigator-led cohort studies (e.g. UK Biobank) to registry data (e.g. Myocardial Ischaemia National Audit Project), providing new means of ascertaining, validating and phenotyping disease. (iii) A common data model in which routine electronic health record data are made research ready, and sharable, by defining and curating with meta-data >300 variables (categorical, continuous, event) on risk factors, CVDs and non-cardiovascular comorbidities. (iv) Transparency: all CALIBER studies have an analytic protocol registered in the public domain, and data are available (safe haven model) for use subject to approvals.

Bleached calcified segments of Halimeda may accumulate in large deposits of economic potential as is the case in the northeastern coast of Brazil. In a survey of the genus in Brazi [...] l based on recent collections and examination of abundant material deposited on Brazilian herbaria we identified seven species: Halimeda cuneata Hering, H. discoidea Decaisne, H. gracilis Harvey ex J. Agardh, H. incrassata (Ellis) Lamouroux, H. opuntia (Linnaeus) Lamouroux, H. simulans Howe and H. tuna (Ellis & Solander) Lamouroux. These species are described in detail, with emphasis on diagnostic characters. Our study has shown that the shape and size of the utricula in surface view, under scanning electron microscopy, can be utilized to discriminate some species. Fertile specimens of Halimeda cuneata and H. discoidea are reported for the first time in the region. Data on vertical and geographical distribution are presented for each species and the southern limit of the genus in the western Atlantic was extended.

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

Directory of Open Access Journals (Sweden)

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

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

Directory of Open Access Journals (Sweden)

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

Lineage-specific fragmentation and nuclear relocation of the mitochondrial cox2 gene in chlorophycean green algae (Chlorophyta).  

Science.gov (United States)

In most eukaryotes the subunit 2 of cytochrome c oxidase (COX2) is encoded in intact mitochondrial genes. Some green algae, however, exhibit split cox2 genes (cox2a and cox2b) encoding two polypeptides (COX2A and COX2B) that form a heterodimeric COX2 subunit. Here, we analyzed the distribution of intact and split cox2 gene sequences in 39 phylogenetically diverse green algae in phylum Chlorophyta obtained from databases (28 sequences from 22 taxa) and from new cox2 data generated in this work (23 sequences from 18 taxa). Our results support previous observations based on a smaller number of taxa, indicating that algae in classes Prasinophyceae, Ulvophyceae, and Trebouxiophyceae contain orthodox, intact mitochondrial cox2 genes. In contrast, all of the algae in Chlorophyceae that we examined exhibited split cox2 genes, and could be separated into two groups: one that has a mitochondrion-localized cox2a gene and a nucleus-localized cox2b gene ("Scenedesmus-like"), and another that has both cox2a and cox2b genes in the nucleus ("Chlamydomonas-like"). The location of the split cox2a and cox2b genes was inferred using five different criteria: differences in amino acid sequences, codon usage (mitochondrial vs. nuclear), codon preference (third position frequencies), presence of nucleotide sequences encoding mitochondrial targeting sequences and presence of spliceosomal introns. Distinct green algae could be grouped according to the form of cox2 gene they contain: intact or fragmented, mitochondrion- or nucleus-localized, and intron-containing or intron-less. We present a model describing the events that led to mitochondrial cox2 gene fragmentation and the independent and sequential migration of cox2a and cox2b genes to the nucleus in chlorophycean green algae. We also suggest that the distribution of the different forms of the cox2 gene provides important insights into the phylogenetic relationships among major groups of Chlorophyceae. PMID:22724135

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

International Nuclear Information System (INIS)

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

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

Science.gov (United States)

Phosphorus and biologically active nitrogen are valuable nutrient resources. Bioremediation with macroalgae is a potential means for recovering nutrients from waste streams. In this study, reject water from anaerobically digested sewage sludge was successfully tested as nutrient source for cultivation of the green macroalgae Ulva lactuca. Maximal growth rates of 54.57±2.16% FW d(-1) were achieved at reject water concentrations equivalent to 50 ?M NH4(+). Based on the results, the growth and nutrient removal was parameterised as function of NH4(+) concentration a tool for optimisation of any similar phycoremediation system. Maximal nutrient removal rates of 22.7 mg N g DW(-1) d(-1) and 2.7 mg P g DW(-1) d(-1) were achieved at reject water concentrations equivalent to 80 and 89 ?M NH4(+), respectively. A combined and integrated use of the produced biomass in a biorefinery is thought to improve the feasibility of using Ulva for bioremediation of reject water. PMID:23954716

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

Development of an Electronic Medical Record Based Alert for Risk of HIV Treatment Failure in a Low-Resource Setting  

Science.gov (United States)

Background The adoption of electronic medical record systems in resource-limited settings can help clinicians monitor patients' adherence to HIV antiretroviral therapy (ART) and identify patients at risk of future ART failure, allowing resources to be targeted to those most at risk. Methods Among adult patients enrolled on ART from 2005–2013 at two large, public-sector hospitals in Haiti, ART failure was assessed after 6–12 months on treatment, based on the World Health Organization's immunologic and clinical criteria. We identified models for predicting ART failure based on ART adherence measures and other patient characteristics. We assessed performance of candidate models using area under the receiver operating curve, and validated results using a randomly-split data sample. The selected prediction model was used to generate a risk score, and its ability to differentiate ART failure risk over a 42-month follow-up period was tested using stratified Kaplan Meier survival curves. Results Among 923 patients with CD4 results available during the period 6–12 months after ART initiation, 196 (21.2%) met ART failure criteria. The pharmacy-based proportion of days covered (PDC) measure performed best among five possible ART adherence measures at predicting ART failure. Average PDC during the first 6 months on ART was 79.0% among cases of ART failure and 88.6% among cases of non-failure (p<0.01). When additional information including sex, baseline CD4, and duration of enrollment in HIV care prior to ART initiation were added to PDC, the risk score differentiated between those who did and did not meet failure criteria over 42 months following ART initiation. Conclusions Pharmacy data are most useful for new ART adherence alerts within iSanté. Such alerts offer potential to help clinicians identify patients at high risk of ART failure so that they can be targeted with adherence support interventions, before ART failure occurs.

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

International Nuclear Information System (INIS)

It is shown that using a novel recycling process of the environmental thermal energy, innovative permanent auto-working direct energy converter systems (PA-DEC systems) from the environmental thermal to electrical and/or chemical potential (TE/CP) energies, abbreviated as PA-TE/CP-DEC systems, can be used for new auto-working electrical power plants and the plants of the compressible and conveyable hydrogen gas resources at various regions in the whole world, with contributions to the world peace and the economical development in the south part of the world. It is shown that the same physical mechanism by free electrons and electrical potential determined by temperature in conductors, which include semiconductors, leads to the Peltier effect and the Seebeck one. It is experimentally clarified that the long distance separation between two ? type elements of the heat absorption (HAS) and the production one (HPS) of the Peltier effect circuit system or between the higher temperature side (HTS) and the lower one (LTS) of the Seebeck effect circuit one does not change in the whole for the both effects. By using present systems, we do not need to use petrified fuels such as coals, oils, and natural gases in order to decrease the greenhouse effect by the CO2 surrounding the earth. Furthermore, we do not need plats of nuclear fissions that left radiating wastes, i.e., with no environmental pollutions. The PA-TE/CP-DEC systems can be applicable for several km scale systems to the micro ones, such as the plants of the electrical power, the compact transportable hydrogen gas resources, a large heat energy container, which can be settled at far place from thermal energy absorbing area, the refrigerators, the air conditioners, home electrical apparatuses, and further the computer elements. It is shown that the simplest PA-TE/CP-DEC system can be established by using only the Seebeck effect components and the resolving water ones. It is clarified that the externally applied electrical energy is used only for the Joule heating in the total resistance of the circuit, and the transportation of heat energy takes place independently from the external electrical source. It is clarified that since we make the innovative PA-TE/CP-DEC systems in thermally open surroundings, the entropy theory established in the closed system is not applicable for the proposed systems.

Use of lanthanides to alleviate the effects of metal ion-deficiency in Desmodesmus quadricauda (Sphaeropleales, Chlorophyta)  

Science.gov (United States)

Lanthanides are biologically non-essential elements with wide applications in technology and industry. Their concentration as environmental contaminants is, therefore, increasing. Although non-essential, lanthanides have been proposed (and even used) to produce beneficial effects in plants, even though their mechanisms of action are unclear. Recently, it was suggested that they may replace essential elements. We tested the effect of low concentrations of lanthanides on the common freshwater microalga Desmodesmus quadricauda, grown under conditions of metal ion-deficiency (lower calcium or manganese concentrations). Our goal was to test if lanthanides can replace essential metals in their functions. Physiological stress was recorded by studying growth and photosynthetic activity using a pulse amplitude modulation (PAM) fluorimeter. We found that nutrient stress reduced parameters of growth and photosynthesis, such as maximal quantum yield, relative electron transport rate, photon capturing efficiency and light saturation irradiance. After adding low concentrations of five lanthanides, we confirmed that they can produce a stimulatory effect on microalgae, depending on the nutrient (metal) deprivation. In the case of a calcium deficit, the addition of lanthanides partly alleviated the adverse effects, probably by a partial substitution of the element. In contrast, with manganese deprivation (and at even lower concentrations), lanthanides enhanced the deleterious effect on cellular growth and photosynthetic competence. These results show that lanthanides can replace essential elements, but their effects on microalgae depend on stress and the nutritional state of the microalgae, raising the possibility of environmental impacts at even low concentrations.

Regulation of gametogenesis and zoosporogenesis in Ulva linza (Chlorophyta): comparison with Ulva mutabilis and potential for laboratory culture.  

Science.gov (United States)

Green Ulvophyte macroalgae represent attractive model systems for understanding growth, development, and evolution. They are untapped resources for food, fuel, and high-value compounds, but can also form nuisance blooms. To fully analyze green seaweed morphogenesis, controlled laboratory-based culture of these organisms is required. To date, only a single Ulvophyte species, Ulva mutabilis Føyn, has been manipulated to complete its whole life cycle in laboratory culture and to grow continuously under axenic conditions. Such cultures are essential to address multiple key questions in Ulva development and in algal-bacterial interactions. Here we show that another Ulva species, U. linza, with a broad geographical distribution, has the potential to be grown in axenic culture similarly to U. mutabilis. U. linza can be reliably induced to sporulate (form gametes and zoospores) in the laboratory, by cutting the relevant thallus tissue into small pieces and removing extracellular inhibitors (sporulation and swarming inhibitors). The germ cells work as an ideal feed stock for standardized algae cultures. The requirement of U. linza for bacterial signals to induce its normal morphology (particularly of the rhizoids) appears to have a species-specific component. The axenic cultures of these two species pave the way for future comparative studies of algal-microbial interactions. PMID:25674100

Full Text Available SciELO Brazil | Language: English Abstract in portuguese A fotoaclimatação da fotossíntese foi investigada numa população tropical de Cladophora glomerata (Estado de São Paulo, sudeste do Brasil, 20º 48’ 24" S e 49º 22’ 24" W) através de parâmetros de fluorescência da clorofila e conteúdo de clorofila a. As plantas foram aclimatadas a dois níveis de 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. Abstract in english Photoacclimation of photosynthesis was investigated in a tropical population of C. glomerata (São Paulo State, southeastern Brazil, 20º 48’ 24" S and 49º 22’ 24" W) by chlorophyll fluorescence parameters and chlorophyll a content. Plants were acclimated to two levels of irradiance: low (65 ± 5 µmol. [...] m-2.s-1) and high (300 ± 10 µmol.m-2.s-1) and exposed short-term (4 days) and long-term (28 days) under a light-dark cycle of 12:12 hours. 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. Initial and final values showed a higher recovery capacity in the short (84.4-90.6%) term exposure than in the long-term case (81.4-81.5%). ETR (electron transport rate) and NPQ (non-photochemical quenching) values were consistently higher under low irradiance. ETR showed a continuous and steady increase along the light exposure period in the short and long-term experiments, whereas NPQ values revealed a rapid increase after 15 se

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

Directory of Open Access Journals (Sweden)

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

Global application of disorders of sex development-related electronic resources: e-learning, e-consultation and e-information sharing.  

Science.gov (United States)

The past 20 years have seen proliferation of electronic (e) resources that promote improved understanding of disorders of sex development (DSD): e-learning for physicians and trainees, e-consultation between clinicians, and e-information for families and affected individuals. Recent e-learning advances have emerged from the European Society for Pediatric Endocrinology's online learning portal for current physicians and trainees. Developed with attention to developing clinical competencies incorporating learning theory, and presenting material that represents international best practice, this e-learning portal offers advances in training, making information more accessible for clinicians and trainees. Multiple levels of instruction, authentic case examples, collaborative forums for physicians and trainees, individualized feedback and user-friendly tools represent advances in trainee and physician learning that can take place in any location. e-consultation is an emerging tool that aims to connect physicians with specialists experienced in DSD care. Although it faces logistical challenges, e-consultation carries the potential to improve DSD care, especially in remote areas with limited access to DSD specialists. e-information for families and patients of all ages is widely accessible online, often with focus on DSD biology, medical care, and psychological and social support. e-information tools aid self-management and support of those affected by DSD. Efforts to improve these resources should aim to map information to individual users, incorporate optimally clear nomenclature, and continue as a 'shared enterprise' of clinicians, affected individuals, families and researchers. Improving the quality of DSD-related e-learning and e-information and developing e-consultation carries the potential to transform DSD care and support for patients, families and physicians worldwide.

Full Text Available SciELO Chile | Language: English Abstract in spanish La 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 dist [...] ribución 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 Abstract in english 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 carboxy [...] lation 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.

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

Cataloging Internet resources.  

Science.gov (United States)

The number of resources available on the Internet continues to expand exponentially, but finding appropriate resources is still a fragmented, hit-or-miss operation. Traditional library expertise in bibliographic description and access should be applied to the management of this emerging body of material. In the process, catalogers will be able to assess the adequacy of current tools (e.g., cataloging codes, machine-readable cataloging formats, integrated library systems) for providing access to Internet resources and will contribute credibly to design or redesign of access tools. This paper outlines the major issues that must be considered in cataloging electronic resources. PMID:7599587

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.

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 – or merging – 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.

Water Resources  

International Nuclear Information System (INIS)

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

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

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 concernstic 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

Energy resources  

International Nuclear Information System (INIS)

On the availability of energy raw materials in the critical transition phase and on the necessity of system analytical availability investigations. An energy policy of consumer countreis with an eye to the future must adapt itself to the fact that the coming decades will be a critical transition phase regarding energy raw material supplies. Supplier and consumer countries will be confronted by a resource crisis in a wide and serious sense of the word during this critical transition phase. The energy policy of a country depending to a large and increasing extent on imports of energy raw materials, such as West Germany, is urgently in need of a realistic estimate of the resources problem. The complex and wide ranging problems of the critical transition phase require crossing of interdisciplinary boundaries and analysis of greater dimensions for their investigation. After available experience in system analysis in the energy field, there is no doubt that a solution of the resources problem is possible using system analytical availability investigations. (orig.)

The Nuclear Receptor Resource Project.  

Science.gov (United States)

We have expanded the original Glucocorticoid Receptor Resource (GRR) database to include several individual resources as part of a larger project called the Nuclear Receptor Resource (NRR). In addition to the GRR, the NRR currently features the Thyroid Hormone Receptor Resource, the Androgen Receptor Resource, the Mineralocorticoid Receptor Resource, the Vitamin D Receptor Resource, and the Steroid Receptor Associated Proteins Resource. The goal of the NRR project is to provide a comprehensive resource for information on the nuclear receptor superfamily, and to provide a forum for the dissemination and discussion of both published and unpublished material on these proteins. Although the individual resources are managed from different servers, all the files are integrated and can be accessed through the project's Home Page, housed at http://nrr. georgetown.edu/nrr.html. In the near future, we hope to expand the project to contain information on other nuclear receptors and to better our electronic publication system. To accomplish this, we encourage the involvement of nuclear receptor investigators in the NRR. PMID:9016529

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.

Science.gov (United States)

A system capable of performing radiography using a beam of electrons. Diffuser means receive a beam of electrons and diffuse the electrons before they enter first matching quadrupoles where the diffused electrons are focused prior to the diffused electrons entering an object. First imaging quadrupoles receive the focused diffused electrons after the focused diffused electrons have been scattered by the object for focusing the scattered electrons. Collimator means receive the scattered electrons and remove scattered electrons that have scattered to large angles. Second imaging quadrupoles receive the collimated scattered electrons and refocus the collimated scattered electrons and map the focused collimated scattered electrons to transverse locations on an image plane representative of the electrons' positions in the object.

Hard material technologies were surveyed to establish the hard electronic technology which offers superior characteristics under hard operational or environmental conditions as compared with conventional Si devices. The following technologies were separately surveyed: (1) The device and integration technologies of wide gap hard semiconductors such as SiC, diamond and nitride, (2) The technology of hard semiconductor devices for vacuum micro- electronics technology, and (3) The technology of hard new material devices for oxides. The formation technology of oxide thin films made remarkable progress after discovery of oxide superconductor materials, resulting in development of an atomic layer growth method and mist deposition method. This leading research is expected to solve such issues difficult to be easily realized by current Si technology as high-power, high-frequency and low-loss devices in power electronics, high temperature-proof and radiation-proof devices in ultimate electronics, and high-speed and dense- integrated devices in information electronics. 432 refs., 136 figs., 15 tabs.

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

Estudos morfométricos e morfológicos foram realizados em populações identificadas como S. leibleinii de acordo com duas abordagens. Na primeira, foram analisadas 11 populações de diferentes localidades e na segunda, duas populações distintas através de coletas mensais durante 11 meses. O diâmetro de filamentos multisseriados, diâmetro e comprimento de células de filamentos multi e unisseriados, presença de constrição, ápice dos filamentos e tipo de sistema basal foram analisados em ambas abordagens. Além disso, estudos cariológicos foram efetuados para complementar as informações taxonômicas. Os resultados revelaram ampla variação morfológica, sendo mais acentuada entre as populações de localidades diferentes que nas mesmas populações ao longo do tempo, mas as características mostraram um gradiente contínuo. Os diferentes tipos de sistemas basais descritos para as espécies do gênero (claviforme, apressório, lobado e rizóides) foram encontrados nas populações estudadas. Esses resultados sugerem que a distinção entre as três espécies é muito frágil e não pode ser apoiada pela diferenciação do sistema basal ou por características métricas. Acredita-se que, por essas razões, o gênero Schizomeris seja composto por uma única espécie. A análise cariológica resultou em n = 12, diferindo de estudos anteriores e algumas possíveis explicações são apresentadas. Abstract in english Schizomeris Kützing is a filamentous alga without ramifications and with differentiated basal attachment system.

The species are di [...] fferentiated mostly by the basal attachment system type. However, the specific taxonomy of the genus is confused. Morphometrical and morphological studies were conducted in populations identified as S. leibleinii according to two approaches. In the first one, 11 populations from different localities were analyzed and in the second, two distinct populations were monthly evaluated during 11 months. Diameter of multiseriate filaments, diameter and length of cells from multi and uniseriate filaments, presence of constriction, form of filament summit, and basal system type were evaluated in both approaches. In addition, karyological studies were conducted to complement taxonomic information. Results revealed a wide morphological variation, being more accentuated among populations from different localities than in the same populations along the time, but the characteristics showed a continuous gradient. The different types of the basal system described for the species of the genus (bluntly rounded, holdfast disc, lobed and rhizoid) were found in the populations studied. These findings suggest that distinction among the three species is very fragile and cannot be supported by differentiation of the basal system or metrical characteristics. Based on present results we consider that Schizomeris is composed by a single species. Karyological analyses resulted in n = 12, differing from previous studies and some possible explanations are discussed.

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

Electron Tree  

DEFF Research Database (Denmark)

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

Uranium resource processing: Secondary resources, India  

International Nuclear Information System (INIS)

While the primary resources of uranium are the main contributors to the industrial uranium production, the secondary resources are becoming important from the viewpoint of eco-friendliness and resource conservation. The secondary resources include uraniferous phosphates processed by the fertiliser industry monazite, which is processed for rare earths elements, uraniferous carbonaceous materials and ultimately seawater. A significant advantage of the secondary resources is that the major cost of mining and processing is borne by the parent valuable content and only the incremental cost of uranium recovery needs to be considered. A second major advantage results from the radiation safety requirements. The primary sources, because of higher uranium content, are associated with higher levels of radioactive daughter products of uranium, which leads to imposition of strict radiological safety norms to mining and processing personnel, industry and environment. Secondary resources, by contrast, require very little additional safety engineering features to be incorporated. (author)

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.

Resolved Electron  

OpenAIRE

Advantages of introducing the electron structure function in electron induced processes are demonstrated. At present energies the same experiment gives more precise description of the electron than photon structure. The momentum scales entering the process are better controlled. At very high momenta probabilistic (partonic) interpretation can be preserved despite strong \\gamma -Z interference. The ``virtual photon'' structure can also be reformulated in terms of more physica...

The electron  

Energy Technology Data Exchange (ETDEWEB)

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.

Bootstrapping Deep Lexical Resources: Resources for Courses  

CERN Document Server

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.

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

Oscillator clustering in a resource distribution chain  

DEFF Research Database (Denmark)

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

International Nuclear Information System (INIS)

To study the present status of the thousand or so electron linacs in the world, and future trends in the field, we have classified these machines according to their use: medical, industrial, and nuclear physics. In the medical category, two types of electron linacs are discussed: the conventional ones which are used for X-ray and electron therapy, and those which may in the future be used for negative pion therapy. The section on industrial machines includes linacs for radiographic and other specialized applications. In the nuclear physics category, the status of conventional low- and medium-energy as well as high duty cycle linacs is reviewed. The question of how one might obtain a C.W., 1 GeV, 100 ?A electron linac is raised and various options using recirculation and stretchers are examined. In this connection, the status of RF superconductivity is summarized. Following, there is a review of linacs for injectors into synchrotrons and e+- storage rings.

Ergonomics in the electronic library.  

Science.gov (United States)

New technologies are changing the face of information services and how those services are delivered. Libraries spend a great deal of time planning the hardware and software implementations of electronic information services, but the human factors are often overlooked. Computers and electronic tools have changed the nature of many librarians' daily work, creating new problems, including stress, fatigue, and cumulative trauma disorders. Ergonomic issues need to be considered when designing or redesigning facilities for electronic resources and services. Libraries can prevent some of the common problems that appear in the digital workplace by paying attention to basic ergonomic issues when designing workstations and work areas. Proper monitor placement, lighting, workstation setup, and seating prevent many of the common occupational problems associated with computers. Staff training will further reduce the likelihood of ergonomic problems in the electronic workplace. PMID:7581189

Electrons most often organize into Fermi-liquid states in which electron-electron interactions play an inessential role. A well known exception is the case of one-dimensional (1D) electron systems (1DES). In 1D the electron Fermi-surface consists of points, and divergences associated with low-energy particle-hole excitations abound when electron-electron interactions are described perturbatively. In higher space dimensions, the corresponding divergences occur only when Fermi...

Electronic Nose and Electronic Tongue  

Science.gov (United States)

Human beings have five senses, namely, vision, hearing, touch, smell and taste. The sensors for vision, hearing and touch have been developed for several years. The need for sensors capable of mimicking the senses of smell and taste have been felt only recently in food industry, environmental monitoring and several industrial applications. In the ever-widening horizon of frontier research in the field of electronics and advanced computing, emergence of electronic nose (E-Nose) and electronic tongue (E-Tongue) have been drawing attention of scientists and technologists for more than a decade. By intelligent integration of multitudes of technologies like chemometrics, microelectronics and advanced soft computing, human olfaction has been successfully mimicked by such new techniques called machine olfaction (Pearce et al. 2002). But the very essence of such research and development efforts has centered on development of customized electronic nose and electronic tongue solutions specific to individual applications. In fact, research trends as of date clearly points to the fact that a machine olfaction system as versatile, universal and broadband as human nose and human tongue may not be feasible in the decades to come. But application specific solutions may definitely be demonstrated and commercialized by modulation in sensor design and fine-tuning the soft computing solutions. This chapter deals with theory, developments of E-Nose and E-Tongue technology and their applications. Also a succinct account of future trends of R&D efforts in this field with an objective of establishing co-relation between machine olfaction and human perception has been included.

The earth's energy resources  

International Nuclear Information System (INIS)

The popular concept that scarce resources must be couserved rather than exploited is challenged. It is pointed out that geological material is not divided into two categories, stone and ore, but contains resources in varying concentrations. Only those concentrations economically recoverable are at any given time regarded as reserves. The illustration of resources in the form of cones where the distance down from the apex represents the work invested and the cross-section area the amount recoverable, is presented. Energy resources have an additional feature, that the energy obtained must exceed appreciably the energy invested. This leads to the cone being modified to a pear-shaped body. The world's reserves of fossil fuels, especially petroleum and uranium and thorium are discussed in this context. (JIW)

Uranium resources and requirements

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)

Space Resource Roundtable Rationale  

Science.gov (United States)

Recent progress in the U.S. Space Program has renewed interest in space resource issues. The Lunar Prospector mission conducted in NASA's Discovery Program has yielded interesting new insights into lunar resource issues, particularly the possibility that water is concentrated in cold traps at the lunar poles. This finding has not yet triggered a new program of lunar exploration or development, however it opens the possibility that new Discovery Missions might be viable. Several asteroid missions are underway or under development and a mission to return samples from the Mars satellite, Phobos, is being developed. These exploration missions are oriented toward scientific analysis, not resource development and utilization, but can provide additional insight into the possibilities for mining asteroids. The Mars Surveyor program now includes experiments on the 2001 lander that are directly applicable to developing propellants from the atmosphere of Mars, and the program has solicited proposals for the 2003/2005 missions in the area of resource utilization. These are aimed at the eventual human exploration of Mars. The beginning of construction of the International Space Station has awakened interest in follow-on programs of human exploration, and NASA is once more studying the human exploration of Moon, Mars and asteroids. Resource utilization will be included as objectives by some of these human exploration programs. At the same time, research and technology development programs in NASA such as the Microgravity Materials Science Program and the Cross-Enterprise Technology Development Program are including resource utilization as a valid area for study. Several major development areas that could utilize space resources, such as space tourism and solar power satellite programs, are actively under study. NASA's interests in space resource development largely are associated with NASA missions rather than the economic development of resources for industrial processes. That is why there is an emphasis in NASA programs on propellant production on Mars - NASA plans missions to Mars, so could make use of those propellants. For other types of applications, however, it will be up to market forces to define the materials and products needed and develop the technologies for extracting them from space resources. Some leading candidates among the potential products from space resources are propellants for other space activities, water from the Moon for use in space, silicon for photovoltaic energy collection in space, and, eventually, He-3 from the Moon for fusion energy production. As the capabilities for manufacturing materials in space are opened up by research aboard the International Space Station, new opportunities for utilization of space resources may emerge. Whereas current research emphasizes increasing knowledge, one program objective should be the development of industrial production techniques for space. These will be based on the development of value-added processing in space, where materials are brought to the space facility, processed there, and returned to Earth. If enough such space processing is developed that the materials transportation requirements are measured in the hundreds of tons a year level, opportunities for substituting lunar materials may develop. The fundamental message is that it is not possible to develop space resources in a vacuum. One must have three things: a recoverable resource, technology to recover it, and a customer. Of these, the customer probably is the most important. All three must be integrated in a space resource program. That is what the Space Resource Roundtable, initiated with this meeting, will bring together.

Uranium resource assessments  

International Nuclear Information System (INIS)

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

Resources and Human Impact  

Science.gov (United States)

Overview: The Resources and Human Impact SciPack explores the role society plays in environmental degradation, and the technological solutions, including resource management, that arises from environmental issues. Human beings modify all components of Earth's ecosystems as they use and consume available resources. The amount and rate of consumption is affected by the population growth and access to technology. This SciPack is focused on Standards and Benchmarks related to interactions in and between ecosystem; population growth and carrying capacity; resource use; and environmental degradation and changes to Earth's systems.In addition to comprehensive inquiry-based learning materials tied to Science Education Standards and Benchmarks, the SciPack includes the following additional components: Pedagogical Implications section addressing common misconceptions, teaching resources and strand maps linking grade band appropriate content to standards. Access to one-on-one support via e-mail to content "Wizards". Final Assessment which can be used to certify mastery of the concepts. Learning Outcomes: Resources and Human Impact: Earth as a System Identify examples of biotic and abiotic interactions within a system. Define carrying capacity. Identify how biotic and abiotic factors limit the carrying capacity of a system. Identify how elements of the environment influence carrying capacity (energy, water, food, minerals). Identify the resources that the human population needs for survival (air, water, food, etc.) Identify which scenario (when given several) is NOT an example of a systematic interaction (feedback loop). Resources and Human Impact: Population Growth, Technology, and the Environment Identify, compare, and contrast principles of population growth in humans and other organisms. Explain the limiting factors on the exponential growth of a population (for example: disease, competition for resources). Analyze how technology (antibiotics, harvesting food) has impacted human population growth in an ecosystem (for example: agriculture, aquaculture). Resources and Human Impact: Environmental Degradation Compare and contrast ways in which different technologies have impacted the environmental system. Differentiate between examples of renewable resources and non-renewable (finite) resources. Analyze how the extraction of each type of energy negatively impacts the environment. Summarize how the burning of fossil fuels is affecting the environment. Assess both local and global environmental impacts when given examples of human resource use. Identify ways in which one human-based environmental change can have a domino-effect on the rest of the ecosystem (when given a scenario). Resources and Human Impact: Using Technology to Address Resource Use Issues Identify the social, political, and economic factors that have affected the development and implementation of technological advances. Identify a technological solution to manage the human impact(s) of a given problem, such as surface mining on the ecosystem. Identify potential risks of implementing a technological solution to manage the human impact(s) upon the ecosystem (for example: unintended outcomes).

NATURAL RESOURCES ASSESSMENT  

Energy Technology Data Exchange (ETDEWEB)

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

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. To maximize this activity NASA Water Resources Program works closely with other government agencies (e.g., the National Oceanic and Atmospheric Administration (NOAA); the U.S. Department of Agriculture (USDA); the U.S. Geological Survey (USGS); the Environmental Protection Agency (EPA), USAID, the Air Force Weather Agency (AFWA)), universities, non-profit national and international organizations, and the private sector. The NASA Water Resources program currently is funding 21 active projects under the functional themes (http://wmp.gsfc.nasa.gov & http://science.nasa.gov/earth-science/applied-sciences/).

Electronic radiology  

International Nuclear Information System (INIS)

Almost all the novel developments achieved since the nineteen seventies in the field of medical imaging techniques rely on the computer. The specialisation in diagnostics that went hand in hand with these developments, together with the increasing pressure for more efficiency, consequentially have led to the necessity of establishing electronic image documentation and data communication systems. The technical basis, such as optical storage media and glass fibre cables, is available. It will depend on the framework conditions with regard to fast implementation and processing whether the advantage of European systems technology will be fully exploited. (orig./HP)

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.

Uranium resources, 1983  

International Nuclear Information System (INIS)

The specific character of uranium as energy resources, the history of development of uranium resources, the production and reserve of uranium in the world, the prospect regarding the demand and supply of uranium, Japanese activity of exploring uranium resources in foreign countries and the state of development of uranium resources in various countries are reported. The formation of uranium deposits, the classification of uranium deposits and the reserve quantity of each type are described. As the geological environment of uranium deposits, there are six types, that is, quartz medium gravel conglomerate deposit, the deposit related to the unconformity in Proterozoic era, the dissemination type magma deposit, pegmatite deposit and contact deposit in igneaus rocks and metamorphic rocks, vein deposit, sandstone type deposit and the other types of deposit. The main features of respective types are explained. The most important uranium resources in Japan are those in the Tertiary formations, and most of the found reserve belongs to this type. The geological features, the state of yield and the scale of the deposits in Ningyotoge, Tono and Kanmon Mesozoic formation are reported. Uranium minerals, the promising districts in the world, and the matters related to the exploration and mining of uranium are described. (Kako, I.)

Evolution and phylogeography of Halimeda section Halimeda (Bryopsidales, Chlorophyta).  

Science.gov (United States)

Nuclear ribosomal and plastid DNA sequences of specimens belonging to section Halimeda of the pantropical green seaweed genus Halimeda show that the group under scrutiny contains many more genetically delineable species than those recognized by classical taxonomy. Discordances between phylograms inferred from nuclear and plastid DNA sequences suggest that reticulate evolution has been involved in speciation within the clade. Nonetheless, our data do not allow ruling out certain alternative explanations for the discordances. Several pseudo-cryptic species are restricted to the margins of the generic distribution range. In a clade of H. cuneata sibling species from widely separated subtropical localities in the Indian Ocean, the South African sibling branches off first, leaving the Arabian and West Australian species as closest relatives. We hypothesize that geographic isolation of the siblings may have taken place following Pleistocene or Pliocene periods of climatic cooling during which subtropical species occupied larger distribution ranges. A more basal separation of Atlantic, Indo-Pacific, and Mediterranean species indicates vicariance. The alternative events that could have caused this vicariance are discussed. PMID:16095924

Chlorophyta and Rhodophyta macroalgae: A source of health promoting phytochemicals.  

Science.gov (United States)

A detailed study of the lipophilic composition of Codium tomentosum, Ulva lactuca, Gracilaria vermiculophylla and Chondrus crispus macroalgae cultivated in the Portuguese coast was carried out by gas chromatography-mass spectrometry before and after alkaline hydrolysis. Their long-chain aliphatic alcohols and monoglycerides compositions are reported for the first time. Additionally, other new compounds were also identified: phytol and neophytadiene in C. tomentosum, U. lactuca and G. vermiculophylla and stigmasterol, ?-tocopherol and 24-methylenecholesterol in C. tomentosum. The lipophilic fraction of the studied macroalgae are mainly constituted by fatty acids (110.1-1030.5mgkg(-1) of dry material) and sterols (14.8-1309.1mgkg(-1) of dry material). C. tomentosum showed to be a valuable source of stigmasterol (1229.0mgkg(-1) of dry material) and ?-tocopherol (21.8mgkg(-1) of dry material). These results are a relevant contribution for the valorisation of these macroalgae species as sources of valuable phytochemicals. PMID:25863619

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.

Electron screening and electron–electron scattering mechanisms  

Energy Technology Data Exchange (ETDEWEB)

Highlights: •The electron–electron scattering accompanied by the diffraction. •The binary or multi-particle mechanism of the electron–electron scattering. •The screening parameter defines the scattering mechanism. •The total scattering field of valence electrons. -- Abstract: The roles of binary and multiple scattering are considered in the context of electron scattering and diffraction on the W(1 1 0) and W(1 1 0) + O(1 × 1) surfaces for energies from 10 to 40 eV. We define a binary scattering mechanism as the incident electron interacting with the field of a valence electron with conservation of the total momentum of the incident and valence electrons. Multi-particle scattering is defined as an interaction of the incoming electron with superposed valence electron fields where determination of the total momentum is not well described. The scattering mechanisms all depend on the electron energy, the density of the scattering electrons and the screening parameter of the Coulomb field in the solid. A model is suggested for the formation of the potential of the scattering field as a superposition of the fields of the screened valence electrons uniformly situated over the first coordination sphere. A quantitative criterion is developed for the binary scattering in which the radial distribution of the scattering potential is normalized to a single charge potential distribution. The model predicts an electron binary scattering mechanism from clean W(1 1 0) and a multi-particle scattering mechanism from W(1 1 0) + O(1 × 1). The results agree with experimental results and imply the validity of the modeled assumptions. The model also shows for electron-pair (e,2e) spectroscopy on metals that the electron–electron interaction occurs predominantly in the vicinity of an atom associated with the diffraction of the incident electron.

Greenland and Natural Resources  

DEFF Research Database (Denmark)

The Greenland development is a story about: Having a hinterland position in relation to the global development. An indigenous people achieving more political influence. How conflicts and discussions on power and ownership of the subsurface resources between a state and an autonomy (Home Rule) can be achieved peacefully through negotiations. How the international society and international organisations (mainly the UN) can facilitate a target oriented process achieving solutions. How a gradual development process can be successful and in a dynamic process lead to economic development. How domestic Greenland policy can delay and maybe change the future of the forecasted development of the use of natural resources. This book is relevant for anyone interested in Greenland in general and the development of Greenland both politically and economically and in relation natural resources.

DSN Resource Scheduling  

Science.gov (United States)

TIGRAS is client-side software, which provides tracking-station equipment planning, allocation, and scheduling services to the DSMS (Deep Space Mission System). TIGRAS provides functions for schedulers to coordinate the DSN (Deep Space Network) antenna usage time and to resolve the resource usage conflicts among tracking passes, antenna calibrations, maintenance, and system testing activities. TIGRAS provides a fully integrated multi-pane graphical user interface for all scheduling operations. This is a great improvement over the legacy VAX VMS command line user interface. TIGRAS has the capability to handle all DSN resource scheduling aspects from long-range to real time. TIGRAS assists NASA mission operations for DSN tracking of station equipment resource request processes from long-range load forecasts (ten years or longer), to midrange, short-range, and real-time (less than one week) emergency tracking plan changes. TIGRAS can be operated by NASA mission operations worldwide to make schedule requests for the DSN station equipment.

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

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.

Regional Resource Planning Study  

International Nuclear Information System (INIS)

Natural gas and electricity commodities are among the most volatile commodities in the world. Spurred on by the recent significant increases in the price of natural gas, the BC Utilities Commission initiated an investigation into factors impacting on natural gas prices, and the validity of the Sumas index (a market trading point, or interchange where multiple pipelines interconnect, allowing the purchase and sale of gas among market participants) as a price setting mechanism. The Commission also sought the opinions and perspectives of the the province's natural gas industry regarding the high volatility of the Sumas gas prices, and as to what could be done to alleviate the wild fluctuations. Following review of the responses from stakeholders, the Commission issued a directive to BC Gas to undertake discussions on regional resource planning with full representation from all stakeholders. This study is the result of the Commission's directive, and is intended to address the issues contained in the directives. Accordingly, the study examined gas demand in the region, demand growth, including power generation, natural gas resource balance in the region, the California impacts on demand and on supply to the region, supply shortfalls on a peak day, and on a seasonal and annual basis, near term remedies, possible resource additions in the longer term, the economic justification for adding major resources and proposed actions to develop needed resource additions. The study clop needed resource additions. The study confirmed the existence of a growing capacity deficit, which limits the supply of natural gas to the region. Near term options to alleviate the regional capacity deficit were found to be limited to discouraging power generation from serving export markets, demand side management efforts, and expansion of the WEI's systems by 105 mmcf/d. Longer term solutions would involve larger scale expansion of WEI's T-South capacity, the BC Gas' Inland Pacific Connector Project and the Washington Lateral proposed by PG and E GTN. 7 tabs., 26 figs

Mining Frequent Closed Patterns using Sample-growth in Resource Effectiveness Data  

Directory of Open Access Journals (Sweden)

Full Text Available As the occurrence of failure of electronic resources is sudden, real-time record analysis on the effectiveness of all resources in the system can discover abnormal resources earlier and start using backup resources or restructure resources in time, thus managing abnormal situations and finally realizing health management of the system. This paper proposed an algorithm: MFPattern, for mining frequent closed resource patterns in resource effectiveness matrix. In order to improve the efficiency, MFPattern algorithm uses sample-growth method and effective pruning strategies to guarantee mining all frequent closed patterns without candidate maintenance. Different from the traditional frequent closed pattern, MFPattern algorithm can mine resource combination patterns with all resources very effective during work, those with simultaneous failure of resources and combination patterns in which some resources are very effective while some other resources have failure. The experimental result shows that our algorithm has more efficiently than existing algorithms.

Alternative energy resources  

International Nuclear Information System (INIS)

Kenya's heavy dependence on petroleum has had an adverse effect on its economy, making it difficult to achieve its development goals. Furthermore, the use of fossil fuels is accompanied by emissions of large quantities of carbon dioxide into the atmosphere - a process that is enhancing the greenhouse effect and subsequent global warming and climate change. This article gives an analysis of the Kenya's current energy scene and discusses its alternative energy resources. Although renewable energies are at present not viable substitutes for oil, the development and exploitation of these energy resources will not only reinforce conservation measures but also promote new trends in technology development

The Prismoid of Resources  

Science.gov (United States)

We define a framework called the prismoid of resources where each vertex refines the ?-calculus by using a different choice to make explicit or implicit (meta-level) the definition of the contraction, weakening, and substitution operations. For all the calculi in the prismoid we show simulation of ?-reduction, confluence, preservation of ?-strong normalisation and strong normalisation for typed terms. Full composition also holds for all the calculi of the prismoid handling explicit substitutions. The whole development of the prismoid is done by making the set of resources a parameter, so that the properties for each vertex are obtained as a particular case of the general abstract proofs.

1999 Pacific Northwest Loads and Resources Study.  

Energy Technology Data Exchange (ETDEWEB)

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

Recycling of electronic scrap  

DEFF Research Database (Denmark)

This Ph.D. thesis deals with the growingly important field of electronics recycling with special attention to the problem of printed circuit board recycling. A literature survey of contemporary electronics recycling and printed circuit board recycling is presented.Further, an analysis of the role of recycling in the modern quest for a sustainable global society is performed, clearly showing that without intensified focus on recycling, the global community cannot hope to reach even the most modest goals for sustainability in resource use. A general method for finding new recycling alternatives in the metals producing industry is presented and tested on two printed circuit board scrap cases. The underlying idea for the method is that complex scrap should be introduced in the matrix of man-made material flows at recipient points where the scrap constitutes the least environmental problem and where resource recovery is largest. It is clearly shown with the two printed circuit board scrap cases that the currently used copper recycling scenario is environmentally inferior to the tin and lead primary production scenarios. The method is a novelty, since no-one has previously put forward a method for the identification of environmentally superior recycling alternatives, which may be used on all kinds of modern scrap, and which can also handle more complex scrap types.The results of the present dissertation can be utilised by e.g. EPAs wishing to advocate environmentally superior recycling alternatives, or by e.g. recycling enterprises wishing to obtain the environmentally best solutions for new recycling systems.

NCBI Viral Genomes Resource  

Science.gov (United States)

Recent technological innovations have ignited an explosion in virus genome sequencing that promises to fundamentally alter our understanding of viral biology and profoundly impact public health policy. Yet, any potential benefits from the billowing cloud of next generation sequence data hinge upon well implemented reference resources that facilitate the identification of sequences, aid in the assembly of sequence reads and provide reference annotation sources. The NCBI Viral Genomes Resource is a reference resource designed to bring order to this sequence shockwave and improve usability of viral sequence data. The resource can be accessed at http://www.ncbi.nlm.nih.gov/genome/viruses/ and catalogs all publicly available virus genome sequences and curates reference genome sequences. As the number of genome sequences has grown, so too have the difficulties in annotating and maintaining reference sequences. The rapid expansion of the viral sequence universe has forced a recalibration of the data model to better provide extant sequence representation and enhanced reference sequence products to serve the needs of the various viral communities. This, in turn, has placed increased emphasis on leveraging the knowledge of individual scientific communities to identify important viral sequences and develop well annotated reference virus genome sets.

Carbon Nanotube Electron Gun  

Science.gov (United States)

An electron gun, an electron source for an electron gun, an extractor for an electron gun, and a respective method for producing the electron gun, the electron source and the extractor are disclosed. Embodiments provide an electron source utilizing a carbon nanotube (CNT) bonded to a substrate for increased stability, reliability, and durability. An extractor with an aperture in a conductive material is used to extract electrons from the electron source, where the aperture may substantially align with the CNT of the electron source when the extractor and electron source are mated to form the electron gun. The electron source and extractor may have alignment features for aligning the electron source and the extractor, thereby bringing the aperture and CNT into substantial alignment when assembled. The alignment features may provide and maintain this alignment during operation to improve the field emission characteristics and overall system stability of the electron gun.

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 andnot 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.

Uranium resources and supply  

International Nuclear Information System (INIS)

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

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.

Geothermal resources of Montana  

Energy Technology Data Exchange (ETDEWEB)

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

Uranium resource assessment activities  

International Nuclear Information System (INIS)

The projected reductions in the growth of nuclear power have reduced the need for information on the long-term supply of uranium (i.e., beyond the year 2000). This change, plus the need to reduce budgets, has led to a modification to the program. As a consequence, the previous plans to carry on a modified National Uranium Resource Evaluation (NURE) Program, focusing on specific geologic areas of World-Class and intermediate-grade deposits, have been abandoned. The program for this fiscal year will focus on the core group of activities that were carried out here in Grand Junction prior to the start of the NURE activity. That core program will involve the collection of basic data from industry and estimation of ore reserves and production capability of the industry, as well as appraisal of potential resources based on company data and data developed in the NURE Program. Collection of other related data, on exploration activity, land holdings, and production, as well as on market activity, will also be continued. This program is expected to provide, as it has in the past, a wide spectrum of reliable information on uranium for use by government and industry explorers, producers, and consumers. The NURE Program has developed an enormous data base on the geochemical and characteristics of much of the country. In the international area, the principal activities will be carried out in cooperation with the OECD Nuclear Energy Agency and the IAEA. These activities will include d the IAEA. These activities will include the publication of biennial reports on world resources, production, and demand; cooperative studies on exploration and production technology; and work with the International Uranium Resource Evaluation Project. This project has completed the study of resources of some ten countries, and has two studies in progress

Electronic Surveillance  

Science.gov (United States)

The FBI maintains a Web site (1) that explains the purposes and ramifications of the Communications Assistance for Law Enforcement Act (CALEA). In addition to discussing the telecommunication industry's role in supporting the act, the site defines electronic surveillance and offers several documents regarding associated legal issues. An excellent source for government surveillance information comes from the Center for Democracy and Technology (2). The material includes an overview of wiretapping and details about government interceptions of Internet communications. Shortly after the terrorist attacks, the Defense Advanced Research Projects Agency began the Total Information Awareness (TIA) Program. This highly controversial project is introduced by the American Civil Liberties Union (3). The site does a good job of describing the objectives of the TIA, and several links to other sources of information are given. In a technical paper published in August 2002 (4), researchers show that optical emanations from telecommunications devices can be monitored remotely. Light emitting diodes, often used as indicators in modems and other data transfer equipment, flash in distinct patterns that could compromise otherwise secure data transmission. Despite being easy to exploit, the authors point out that this vulnerability would generally be simple to fix. A news story from May 16, 2003 (5) highlights a recent US Government report stating that secure telephones can be wiretapped nearly as easily as standard phones. The article is accompanied by links to the original report and an essay on security. Companies often monitor employee computer and email activity. A law professor from Bentley College writes about workplace privacy in an essay from 2003 (6). Citing a number of hypothetical examples, the author weighs the employees' rights versus those of the company. The technical implementation of the aforementioned CALEA is described in a detailed article from May 2003 (7). The needs of law enforcement are compared to what is achieved with the resulting systems and technology, and a few statistics are included to show that electronic surveillance can be effective. Lastly, an article from PC World (8) reports that the US Government is seeking to increase its surveillance of email and Web usage. The article includes a link to the 120-page draft of the Domestic Security Enhancement Act of 2003.

El Nino Resources  

Science.gov (United States)

El Nino Resources, a product of the Coaps Library at Florida State University, provides a comprehensive list of resources on eight different topics dealing with El Nino, such as bibliographies, web pages, online articles, movies, and dissertations. 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).

Review - Water resources development  

International Nuclear Information System (INIS)

For the past 15 years the possibilities of employing nuclear explosives to develop and manage water resources for the benefit of man have been studied, Experimental and theoretical studies of many types have been undertaken. Numerous applications have been considered including site studies for particular projects. Attention has been given to the economics of specific applications, to hazards and safety problems, to legal limitations, to geologic and hydrologic considerations, and to effects on water quality. The net result of this effort has been the development of a large body of knowledge ready to be drawn upon wherever and whenever needed. Nuclear explosives are important tools for water resources development; they must be carefully selected so as to serve their intended purpose at minimum cost with few side effects. (author)

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 systems 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 cost 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

Cockpit resource management training  

Science.gov (United States)

The 6th General Flight Crew Training Meeting held in Montreal in May, 1984 was for most IATA member airlines the first time they had been exposed to what was then a relatively new aspect of flight crew training-resource management training. In reviewing the results of this meeting the IATA Flight Crew Training SubCommittee (FCTSC), which had been responsible for the agenda and the meeting itself, concluded that because very few airlines had implemented a program or even appeared to understand the term resource management, a member airline survey should be conducted and the results analyzed. This presentation shows the results of that survey in a form which can be related to the topics of the workshop.

Ensembl variation resources  

Directory of Open Access Journals (Sweden)

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

Using wastes as resources  

International Nuclear Information System (INIS)

The collection, treatment, and disposal of domestic and industrial wastewater, garbage, and other wastes present considerable problems in urban and semiurban areas of developing countries. Major benefits of using integrated treatment and resource recovery systems include waste stabilization, recovering energy as biogas, producing food from algae and fish, irrigation, improved public health, and aquatic weed control and use. Information and research are needed, however, to assesss the appropriateness, benefits, and limitations of such technology on a large scale. System configuration depends on the types and quantities of wastes available for processing. There must be enough collectable waste for the system to be viable. Information should be gathered to asses whether there is a net public health benefit by implementing a waste treatment and resource recovery system. Benefits such as savings in medical expenses and increased worker productivity due to improved health may be difficult to quantify. The potential health risks created by implementing a resource recovery system should be studied. The most difficult issues to contend with are socioeconomic in nature. Often, the poor performance of a proven technology is attributed to a lack of proper understanding of its principles by the operators, lack of community interest, improper operator training, and poor management. Public education to motivate people to accept technologies that are beneficial to them is importantthat are beneficial to them is important

Resource Balancing Control Allocation  

Science.gov (United States)

Next generation aircraft with a large number of actuators will require advanced control allocation methods to compute the actuator commands needed to follow desired trajectories while respecting system constraints. Previously, algorithms were proposed to minimize the l1 or l2 norms of the tracking error and of the control effort. The paper discusses the alternative choice of using the l1 norm for minimization of the tracking error and a normalized l(infinity) norm, or sup norm, for minimization of the control effort. The algorithm computes the norm of the actuator deflections scaled by the actuator limits. Minimization of the control effort then translates into the minimization of the maximum actuator deflection as a percentage of its range of motion. The paper shows how the problem can be solved effectively by converting it into a linear program and solving it using a simplex algorithm. Properties of the algorithm are investigated through examples. In particular, the min-max criterion results in a type of resource balancing, where the resources are the control surfaces and the algorithm balances these resources to achieve the desired command. A study of the sensitivity of the algorithms to the data is presented, which shows that the normalized l(infinity) algorithm has the lowest sensitivity, although high sensitivities are observed whenever the limits of performance are reached.

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

Research on the rare metal resources, (1)  

International Nuclear Information System (INIS)

The zirconium deposit of the Pocos de Caldas Plateau is north of Sa tilde o Paulo, Brasil, on the boundary between the States of Minas Gerais and Sa tiled o Paulo. The zirconium ore was formed as a mixture of baddeleyite (ZrO2) and zircon (ZrSiO4) which was identified as caldasite from the microscopic, X-ray and electron microprobe studies. This ore also contained a high content of uranium and thorium oxides, enough for nuclear fuel resources from the ?-ray spectrometry. The ore shows stable behavior in the TG-DTA studies but the metamictization by the ? radiation damage from uranium and thorium seems to have occurred. The possible production process of zirconium from the caldasite was discussed mainly in the distillation process. Finally the evaluation of the caldasite as a zirconium resource was conducted from the metallurgical point of view. (author)

EDITORIAL: Synaptic electronics Synaptic electronics  

Science.gov (United States)

Conventional computers excel in logic and accurate scientific calculations but make hard work of open ended problems that human brains handle easily. Even von Neumann—the mathematician and polymath who first developed the programming architecture that forms the basis of today's computers—was already looking to the brain for future developments before his death in 1957 [1]. Neuromorphic computing uses approaches that better mimic the working of the human brain. Recent developments in nanotechnology are now providing structures with very accommodating properties for neuromorphic approaches. This special issue, with guest editors James K Gimzewski and Dominique Vuillaume, is devoted to research at the serendipitous interface between the two disciplines. 'Synaptic electronics', looks at artificial devices with connections that demonstrate behaviour similar to synapses in the nervous system allowing a new and more powerful approach to computing. Synapses and connecting neurons respond differently to incident signals depending on the history of signals previously experienced, ultimately leading to short term and long term memory behaviour. The basic characteristics of a synapse can be replicated with around ten simple transistors. However with the human brain having around 1011 neurons and 1015 synapses, artificial neurons and synapses from basic transistors are unlikely to accommodate the scalability required. The discovery of nanoscale elements that function as 'memristors' has provided a key tool for the implementation of synaptic connections [2]. Leon Chua first developed the concept of the 'The memristor—the missing circuit element' in 1971 [3]. In this special issue he presents a tutorial describing how memristor research has fed into our understanding of synaptic behaviour and how they can be applied in information processing [4]. He also describes, 'The new principle of local activity, which uncovers a minuscule life-enabling "Goldilocks zone", dubbed the edge of chaos, where complex phenomena, including creativity and intelligence, may emerge'. Also in this issue R Stanley Williams and colleagues report results from simulations that demonstrate the potential for using Mott transistors as building blocks for scalable neuristor-based integrated circuits without transistors [5]. The scalability of neural chip designs is also tackled in the design reported by Narayan Srinivasa and colleagues in the US [6]. Meanwhile Carsten Timm and Massimiliano Di Ventra describe simulations of a molecular transistor in which electrons strongly coupled to a vibrational mode lead to a Franck-Condon (FC) blockade that mimics the spiking action potentials in synaptic memory behaviour [7]. The 'atomic switches' used to demonstrate synaptic behaviour by a collaboration of researchers in California and Japan also come under further scrutiny in this issue. James K Gimzewski and colleagues consider the difference between the behaviour of an atomic switch in isolation and in a network [8]. As the authors point out, 'The work presented represents steps in a unified approach of experimentation and theory of complex systems to make atomic switch networks a uniquely scalable platform for neuromorphic computing'. Researchers in Germany [9] and Sweden [10] also report on theoretical approaches to modelling networks of memristive elements and complementary resistive switches for synaptic devices. As Vincent Derycke and colleagues in France point out, 'Actual experimental demonstrations of neural network type circuits based on non-conventional/non-CMOS memory devices and displaying function learning capabilities remain very scarce'. They describe how their work using carbon nanotubes provides a rare demonstration of actual function learning with synapses based on nanoscale building blocks [11]. However, this is far from the only experimental work reported in this issue, others include: short-term memory of TiO2-based electrochemical capacitors [12]; a neuromorphic circuit composed of a nanoscale 1-kbit resistive random-access memory (RRAM

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.

Renewable but expensive resources  

International Nuclear Information System (INIS)

The rapidly growing share of renewable resources in electricity production can also be evident in the wallets of consumers. Renewable resources, compared to traditional production, are many times more expensive. It applies mainly to solar energy, which is generously subsidized by the state via the highest purchasing prices of all the alternatives, and it also contributes for technologies through Euro funds. Countries like Germany or the Czech Republic - where the high purchasing prices of electricity produced by solar energy has led to a monumental boom in the business - are regressing. They want to lower the substantial purchasing prices. Also Slovak Electricity Transmission System wants to reduce solar energy facilities by determining the maximum performance capacity. The Institute of Energy Safety deems the pressure on consumer prices as evident of the renewable resources boom. 'Higher purchasing prices for OZE electricity, especially from photovoltaic power plants, will start influencing the consumer's end price. Households and all other consumers will pay more for electricity,' states the Institute in its analysis. At the current price rate for electricity signifies that just the buying of electricity produced from photovoltaic plants, wind and bio gas would lead to a year-to-year growth of annual electricity expenses by 4 to 8.4% for households with an average consumption of 2333 KWh. An average household with a 2.3 MWh consumption will pay a little bit more thaconsumption will pay a little bit more than 311 euros for electricity this year. If there had already existed 100 MW of installed power in photovoltaic, wind and biogas electricity power stations in Slovakia this year, the annual bill would have gone up by 4.3%. The moderate impact on the price of electricity is confirmed by the experience of East Slovak Distribution. 'In 2008 and 2009, the advance determined purchasing price for electricity appeared in the final result as high as 0.5 to 1%,' said Andrea Danihelova to TREND, spokeperson of the company. (author)

The financial resource curse  

OpenAIRE

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...

We present an overview of the quantitative theory of single-copy entanglement in finite-dimensional quantum systems. In particular we emphasize the point of view that different entanglement measures quantify different types of resources, which leads to a natural interdependence of entanglement classification and quantification. Apart from the theoretical basis, we outline various methods for obtaining quantitative results on arbitrary mixed states. This article is part of a special issue of Journal of Physics A: Mathematical and Theoretical devoted to ‘50 years of Bell’s theorem’.

Action Research Resources  

Science.gov (United States)

Action research can be described as a family of research methodologies which pursue action (or change) and research (or understanding) at the same time. In most of its forms it does this by using a cyclic or spiral process which alternates between action and critical reflection and in the later cycles, continuously refining methods, data and interpretation in the light of the understanding developed in the earlier cycles. There are extensive descriptions of many different ways to conduct an evaluation and links to other resources about action research.

HUMAN RESOURCE MANAGEMENT & TECHNOLOGICAL CRISIS  

Directory of Open Access Journals (Sweden)

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