    The responses of the interspecific competition between Skeletonema costatum and Heterosigma akashiwo to UV-B radiation enhancement were studied by the co-culture method. The results showed that Heterosigma akashiwo exhibited inhibition on the growth of Skeletonema costatum, and with the increase of initial inoculation density of Heterosigma akashiwo, heavier inhibition on Skeletonema costatum appeared. Under different inoculation proportions, Heterosigma akashiwo could always be in predominance in competition with Skeletonema costatum. The UV-B radiation treatment could change the competition relationship between Skeletonema costatum and Heterosigma akashiwo, which could increase the competitive dominance of Skeletonema costatum and decrease the competitive dominance of Heterosigma akashiwo. When the inoculation proportions of Heterosigma akashiwo and Skeletonema costatum were H:S=1:4 and H:S=1:1, Skeletonema costatum was in predominance in this competition; however, Heterosigma akashiwo was in predominance when the inoculation proportion was H:S=4:1.

    To rapidly detect the harmful algae H. Akashiwo qualitatively and quantitatively, sequences of the 18S rDNA deduced from H. Akashiwo were used for designing species-specific primers, and a RFQ-PCR (Real-time Fluorescent Quantitative Polymerase Chain Reaction) method was developed for quantitative detection of H.akashiwo. Primer H. Akashiwo and TaqMan probe were designed, and the specificity of primer was checked with PCR. A calibration curve was constructed with cycle threshold value against visual counted cell number. And the value of the curve was tested with other H. Akashiwo samples, which were assayed with both the RFQ-PCR method and visual count under microscope.

  3. The effects of the harmful alga Heterosigma akashiwo on cultures of Schmackeria inopinus (Copepoda, Calanoida) (United States)

    Yu, Juan; Yang, Guipeng; Tian, Jiyuan


    Harmful effects of red tide dinoflagellates on copepods have gained particular attention in recent years. In this study, monocultures and mixed cultures of the harmful alga Heterosigma akashiwo and the non-harmful alga Isochrysis galbana were utilized as diets to investigate the ingestion, reproduction and recruitment of the copepod Schmackeria inopinus. When compared with a monoculture of I. galbana, a sole diet H. akashiwo apparently inhibited ingestion rates, proportions of gravid female (PGFs), egg production rates (EPRs), gross growth efficiencies (GGEs) and recruitment of S. inopinus. We found that the harmful effects of H. akashiwo on the abundance of S. inopinus were concentration- and time-dependent. S. inopinus exhibited significantly reduced ingestion rates, EPRs and GGEs when they were fed on food mixtures of H. akashiwo (0-75% of I. galbana) in comparison with the control diet (100% of I. galbana). The data on ingestion rates and EPRs in the diet mixtures suggest that H. akashiwo is toxic to S. inopinus, which might be attributable to the glycocalyx structures in the H. akashiwo cell surface. The results in this study indicate that a bloom of H. akashiwo could cause significant stress to S. inopinus.

    Higashi, Aiko; Fujitani, Yoshiko; Nakayama, Natsuko; Tani, Akio; Ueki, Shoko


    Algal bloom is typically caused by aberrant propagation of a single species, resulting in its predomination in the local population. While environmental factors including temperature and eutrophication are linked to bloom, the precise mechanism of its formation process is still obscure. Here, we isolated a bacterial strain that promotes growth of Heterosigma akashiwo, a Raphidophyceae that causes harmful algal blooms. Based on 16S rRNA gene sequence, the strain was identified as Altererythrobacter ishigakiensis, a member of the class Alphaproteobacteria. When added to culture, this strain facilitated growth of H. akashiwo and increased its cell culture yield significantly. Importantly, this strain did not affect the growth of other raphidophytes, Chattonella ovate and C. antiqua, indicating that it promotes growth of H. akashiwo in a species-specific manner. We also found that, in co-culture, H. akashiwo suppressed the growth of C. ovate. When A. ishigakiensis was added to the mixed culture, H. akashiwo growth was facilitated while C. ovate propagation was markedly suppressed, indicating that the presence of the bacterium enhances the dominance of H. akashiwo over C. ovate. This is the first example of selective growth promotion of H. akashiwo by a marine bacterium, and may exemplify importance of symbiotic bacterium on algal bloom forming process in general.

  5. Remote sensing of Akashiwo sanguinea in the vertical column (United States)

    Moore, K.; Broughton, J.; Kudela, R. M.


    Harmful algal blooms can be extremely damaging to both humans and marine organisms. Harmful algal blooms have been known to cause deleterious effects due to either toxin production or enhanced biomass; mass mortalities of sea birds, dolphins and other creatures often result. Incidences of harmful algal blooms are increasing, so quantifying their locations is a pressing need for human health and the health of marine ecosystems. Past studies have used remote sensing to image dinoflagellate blooms at the ocean surface, but due to migrations of the dinoflagellates in the water column, surface blooms often correspond to non-optimal solar zenith angles for remote sensing imaging. Here we demonstrate a way to locate the blooms of Akashiwo sanguinea at depth in turbid, coastal water (Case II ocean water). Using Hydrolight to simulate the optical properties of A. sanguinea in Monterey Bay, we develop spectral profiles of dinoflagellate blooms in the vertical column. Spectral mixing analysis is used to process aerial data in ENVI-IDL image analysis software. Application of the model to SAMSON remote sensing imagery reveals strong biological and physical coupling in Monterey Bay, and distinguishes dinoflagellates at the surface from those at greater depth. The model is robust and holds up well under various atmospheric forcings and ocean conditions. This work suggests that harmful algal blooms can be detected far below the ocean surface, with the possibility of tracking dinoflagellate diel migrations in the vertical column from outer space.

    Two species of marine phytoplankton,Platymonas helgolandicavar. tsingtaoensis andHeterosigma akashiwo, were cul-tivated in bi-algal cultures to investigate the effect of anthracene (ANT) on the interaction between them. Without ANT,H. akashiwo out-competedP. helgolandica at low initial biomass ratios (P. helgolandica (P): H. akashiwo (H)=1:4 and 1:1), but not at the highest (P:H=4:1). This observation was consistent with the description in Lotka-Volterra two species competition model. It was found that P. helgolandica was excluded at low initial biomass ratios, while the unstable equilibrium between two species was predicted at the highest. For both species, carrying capacity and maximal specific growth rate decreased in bi-algal cultures compared to those in monocultures.H. akashiwo exhibited a higher sensitivity to ANT thanP. helgolandica. This resulted markedly in a reduced cell den-sity ofH. akashiwo but an increased cell density ofP. helgolandica. Carrying capacity ofP. helgolandica was consistently higher in bi-algal cultures with ANT than those without ANT, suggesting that ANT, through the elimination ofH. akashiwo, generated the dominance ofP. helgolandica independently of initial biomass ratios. This study showed a density-dependent effect of harmful alga (H. akashiwo) on dietary alga (P. helgolandica), and indicated that ocean pollutant ANT could induce the succession of marine phytoplankton.

    Two species of marine phytoplankton, Platymonas helgolandica var. tsingtaoensis and Heterosigma akashiwo, were cultivated in bi-algal cultures to investigate the effect of anthracene (ANT) on the interaction between them. Without ANT, H. akashiwo out-competed P. helgolandica at low initial biomass ratios ( P. helgolandica ( P): H. akashiwo ( H) = 1:4 and 1:1), but not at the highest ( P: H = 4:1). This observation was consistent with the description in Lotka-Volterra two species competition model. It was found that P. helgolandica was excluded at low initial biomass ratios, while the unstable equilibrium between two species was predicted at the highest.

  8. [Effects of Ulva pertusa and Gracilaria lemaneiformis on growth of Heterosigma akashiwo (Raphidophyceae) in co-culture]. (United States)

    Wang, You; Yu, Zhi-ming; Song, Xiu-xian; Zhang, Shan-dong


    We studied the effects of fresh tissue and culture medium filtrate of two species of macroalgae, Ulva pertusa (Chlorophyta) and Gracilaria lemaneiformis (Rhodophyta) on growth of Heterosigma akashiwo (Raphidophyceae) in co-culture. Both U. pertusa and G. lemaneiformis, and especially their fresh tissues, significantly impede the growth of H. akashiwo. Carbonate limitations and the presence of environment bacteria are not necessary for the negative effects of macroalgal on H. akashiwo. The simultaneous nutrient assays show that nitrate and phosphate are almost exhausted in the G. lemaneiformis co-culture system, but remain at acceptable levels in the U. pertusa system, when all cells of H. akashiwo are completely dead. When f/2 medium is supplied daily to G. lemaneiformis culture, the growth of H. akashiwo is greatly inhibited but not completely terminated. Furthermore, different amounts of fresh seaweed tissue, and culture medium filtrate prepared from different macroalgal concentrations are analyzed to determine their effects on the growth of H. akashiwo. The results show a positive correlation between the initial macroalgal concentration and the negative effects they exert on the co-cultured microalgae. Results suggest that the allelopathic effects of U. pertusa may be essential for negative effects on H. akashiwo; however, the combined roles of allelopathy and nutrient competition may be responsible for the negative effect of G. lemaneiformis the release of allelochemicals by U. pertusa.

    Full Text Available In the period of February-May 2012, harmful algal blooms (HABs along with environmental factors were investigated biweekly in the Golden Horn Estuary at the northeast of the Sea of Marmara and a dense bloom of the raphidophyceaen Heterosigma akashiwo (Y.Hada Y.Hada ex Y.Hara & M.Chihara was observed in late May. H. akashiwo abundance increased gradually from the lower estuary to the upper estuary. The dense bloom of H. akashiwo in late May occurred at the temperature of 20.2°C and salinity of 16.4 psu and its abundance reached to 10.4×106 cells L-1. When compared to mid-May, the mean temperature of surface water increased 4.50°C, while salinity decreased 2.30 psu in late May. Secchi depth values decreased rapidly from the lower to the upper estuary (6.00 m to 0.50 m. It is considered that a rapid increase in temperature, a decrease in salinity, and high nutrient concentrations in combination with low water circulation at the upper estuary were the causes of the bloom of H. akashiwo. Fish mortality or other harmful effects in environment were not observed during the H. akashiwo bloom. But, these events may create a potentially toxic risk for the study area in the future.

  10. Feeding by the heterotrophic dinoflagellate Oxyrrhis marina on the red-tide raphidophyte Heterosigma akashiwo: a potential biological method to control red tides using mass-cultured grazers. (United States)

    Jeong, Hae Jin; Kim, Jae Seong; Yoo, Yeong Du; Kim, Seong Taek; Kim, Tae Hoon; Park, Myung Gil; Lee, Chang Hoon; Seong, Kyeong Ah; Kang, Nam Seon; Shim, Jae Hyung


    As part of the development of a method to control the outbreak and persistence of red tides using mass-cultured heterotrophic protist grazers, we measured the growth and ingestion rates of cultured Oxyrrhis marina (a heterotrophic dinoflagellate) on cultured Heterosigma akashiwo (a raphidophyte) in bottles in the laboratory and in mesocosms (ca. 60 liter) in nature, and those of the cultured grazer on natural populations of the red-tide organism in mesocosms set up in nature. In the bottle incubation, specific growth rates of O. marina increased rapidly with increasing concentration of cultured prey up to ca. 950 ng C ml(-1) (equivalent to 9,500 cells ml(-1)), but were saturated at higher concentrations. Maximum specific growth rate (mumax), KGR (prey concentration sustaining 0.5 mumax) and threshold prey concentration of O. marina on H. akashiwo were 1.43 d(-1), 104 ng C ml(-1), and 8.0 ng C ml(-1), respectively. Maximum ingestion and clearance rates of O. marina were 1.27 ng C grazer(-1) d(-1) and 0.3 microl grazer(-1) h(-1), respectively. Cultured O. marina grew well effectively reducing cultured and natural populations of H. akashiwo down to a very low concentration within 3 d in the mesocosms. The growth and ingestion rates of cultured O. marina on natural populations of H. akashiwo in the mesocosms were 39% and 40%, respectively, of those calculated based on the results from the bottle incubation in the laboratory, while growth and ingestion rates of cultured O. marina on cultured H. akashiwo in the mesocosms were 55% and 36%, respectively. Calculated grazing impact by O. marina on natural populations of H. akashiwo suggests that O. marina cultured on a large scale could be used for controlling red tides by H. akashiwo near aquaculture farms that are located in small ponds, lagoons, semi-enclosed bays, and large land-aqua tanks to which fresh seawater should be frequently supplied.

  11. Chloroplast His-to-Asp signal transduction: a potential mechanism for plastid gene regulation in Heterosigma akashiwo (Raphidophyceae

    Directory of Open Access Journals (Sweden)

    Jacobs Michael A


    Full Text Available Abstract Background Maintenance of homeostasis requires that an organism perceive selected physical and chemical signals within an informationally dense environment. Functionally, an organism uses a variety of signal transduction arrays to amplify and convert these perceived signals into appropriate gene transcriptional responses. These changes in gene expression serve to modify selective metabolic processes and thus optimize reproductive success. Here we analyze a chloroplast-encoded His-to-Asp signal transduction circuit in the stramenopile Heterosigma akashiwo (Hada Hada ex Y. Hara et Chihara [syn. H. carterae (Hulburt F.J.R. Taylor]. The presence, structure and putative function of this protein pair are discussed in the context of their evolutionary homologues. Results Bioinformatic analysis of the Heterosigma akashiwo chloroplast genome sequence revealed the presence of a single two-component His-to-Asp (designated Tsg1/Trg1 pair in this stramenopile (golden-brown alga. These data represent the first documentation of a His-to-Asp array in stramenopiles and counter previous reports suggesting that such regulatory proteins are lacking in this taxonomic cluster. Comparison of the 43 kDa H. akashiwo Tsg1 with bacterial sensor kinases showed that the algal protein exhibits a moderately maintained PAS motif in the sensor kinase domain as well as highly conserved H, N, G1 and F motifs within the histidine kinase ATP binding site. Molecular modelling of the 27 kDa H. akashiwo Trg1 regulator protein was consistent with a winged helix-turn-helix identity – a class of proteins that is known to impact gene expression at the level of transcription. The occurrence of Trg1 protein in actively growing H. akashiwo cells was verified by Western analysis. The presence of a PhoB-like RNA polymerase loop in Trg1 and its homologues in the red-algal lineage support the hypothesis that Trg1 and its homologues interact with a sigma 70 (σ70 subunit (encoded by

    Phytoplankton blooms are a worldwide problem and can greatly affect ecological processes in aquatic systems, but its impacts on the functional potential of microbial communities are limited. In this study, a high-throughput microarray-based technology (GeoChip) was used to profile the functional potential of free-living microbes from the Xiamen Sea Area in response to a 2011 Akashiwo sanguinea bloom. The bloom altered the overall community functional structure. Genes that were significantly (p information on the relationship of algae to other microbes in aquatic systems, and provides new insights into our understanding of ecological impacts of phytoplankton blooms.

  13. Evolution and Phylogeny of Large DNA Viruses, Mimiviridae and Phycodnaviridae Including Newly Characterized Heterosigma akashiwo Virus (United States)

    Maruyama, Fumito; Ueki, Shoko


    Nucleocytoplasmic DNA viruses are a large group of viruses that harbor double-stranded DNA genomes with sizes of several 100 kbp, challenging the traditional concept of viruses as small, simple ‘organisms at the edge of life.’ The most intriguing questions about them may be their origin and evolution, which have yielded the variety we see today. Specifically, the phyletic relationship between two giant dsDNA virus families that are presumed to be close, Mimiviridae, which infect Acanthamoeba, and Phycodnaviridae, which infect algae, is still obscure and needs to be clarified by in-depth analysis. Here, we studied Mimiviridae–Phycodnaviridae phylogeny including the newly identified Heterosigma akashiwo virus strain HaV53. Gene-to-gene comparison of HaV53 with other giant dsDNA viruses showed that only a small proportion of HaV53 genes show similarities with the others, revealing its uniqueness among Phycodnaviridae. Phylogenetic/genomic analysis of Phycodnaviridae including HaV53 revealed that the family can be classified into four distinctive subfamilies, namely, Megaviridae (Mimivirus-like), Chlorovirus-type, and Coccolitho/Phaeovirus-type groups, and HaV53 independent of the other three groups. Several orthologs found in specific subfamilies while absent from the others were identified, providing potential family marker genes. Finally, reconstruction of the evolutionary history of Phycodnaviridae and Mimiviridae revealed that these viruses are descended from a common ancestor with a small set of genes and reached their current diversity by differentially acquiring gene sets during the course of evolution. Our study illustrates the phylogeny and evolution of Mimiviridae–Phycodnaviridae and proposes classifications that better represent phyletic relationships among the family members. PMID:27965659

    The accurate measurement of gene expression via quantitative real-time reverse transcription PCR (qRT-PCR) heavily relies on the choice of valid reference gene(s) for data normalization. Resting cyst is the dormant stage in the life cycle of dinoflagellate, which plays crucial roles in HAB-forming dinoflagellate ecology. However, only limited investigations have been conducted on the reference gene selection in dinoflagellates. Gap remained in our knowledge about appropriate HKGs for normalizing gene expression in different life stages, which laid obstacles for the application of qRT-PCR to the HAB-forming group. In this study, six candidate reference genes, 18S ribosomal RNA (18S), glyceraldehyde-3-phosphate dehydrogenase (GAPDH),α-tubulin (TUA),β-tubulin (TUB), actin (ACT) and cytochrome oxidase subunit 1 (COX1), were evaluated for their expression stability with qRT-PCR and three statistical algorithms (GeNorm, NormFinder, and BestKeeper) for the cosmopolitan, harmful algal bloom-forming dinoflagellateAkashiwo sanguinea. Expression patterns were observed across 18 biological samples, including cells at resting stages (resting cysts), different growth stages, in darkness, exposed to abscisic acid (ABA) and exposed to temperature stress. The results indicated thatTUA,18S andGAPDH were relatively stable across all tested scenarios. While the best-recommended reference genes differed across experimental groups, the pairs ofACT andTUA,18S andGAPDH were the most reliable for cells at different growth stages and darkness treatment. The combination ofTUA andTUB was the best choice for normalization in resting cysts and in ABA treatment, respectively. The pair ofACT andCOX1 was suitable for temperature treatments. This study was the first to investigate the stable internal reference genes in dinoflagellates at different stages of life cycle, particularly in resting cysts. Our results provided useful information for selection of reference genes in dinoflagellates

  19. An Improved Quantitative Real-Time PCR Assay for the Enumeration of Heterosigma akashiwo (Raphidophyceae) Cysts Using a DNA Debris Removal Method and a Cyst-Based Standard Curve. (United States)

    Kim, Joo-Hwan; Kim, Jin Ho; Wang, Pengbin; Park, Bum Soo; Han, Myung-Soo


    The identification and quantification of Heterosigma akashiwo cysts in sediments by light microscopy can be difficult due to the small size and morphology of the cysts, which are often indistinguishable from those of other types of algae. Quantitative real-time PCR (qPCR) based assays represent a potentially efficient method for quantifying the abundance of H. akashiwo cysts, although standard curves must be based on cyst DNA rather than on vegetative cell DNA due to differences in gene copy number and DNA extraction yield between these two cell types. Furthermore, qPCR on sediment samples can be complicated by the presence of extracellular DNA debris. To solve these problems, we constructed a cyst-based standard curve and developed a simple method for removing DNA debris from sediment samples. This cyst-based standard curve was compared with a standard curve based on vegetative cells, as vegetative cells may have twice the gene copy number of cysts. To remove DNA debris from the sediment, we developed a simple method involving dilution with distilled water and heating at 75°C. A total of 18 sediment samples were used to evaluate this method. Cyst abundance determined using the qPCR assay without DNA debris removal yielded results up to 51-fold greater than with direct counting. By contrast, a highly significant correlation was observed between cyst abundance determined by direct counting and the qPCR assay in conjunction with DNA debris removal (r2 = 0.72, slope = 1.07, p cysts in sediment samples.

  1. West Africa (United States)


    With its vast expanses of sand, framed by mountain ranges and exposed rock, northwestern Africa makes a pretty picture when viewed from above. This image was acquired by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA's Terra spacecraft. The Canary Islands can be seen on the left side of the image just off Africa's Atlantic shore. The light brown expanse running through the northern two thirds of the image is the Sahara Desert. The desert runs up against the dark brown Haut Atlas mountain range of Morocco in the northwest, the Atlantic Ocean to the west and the semi-arid (light brown pixels) Sahelian region in the South. The Sahara, however, isn't staying put. Since the 1960s, the desert has been expanding into the Sahelian region at a rate of up to 6 kilometers per year. In the 1980s this desert expansion, combined with over cultivation of the Sahel, caused a major famine across west Africa. Over the summer months, strong winds pick up sands from the Sahara and blow them across the Atlantic as far west as North America, causing air pollution in Miami and damaging coral reefs in the Bahamas and the Florida Keys. The white outlines on the map represent country borders. Starting at the top-most portion of the map and working clockwise, the countries shown are Morocco, Western Sahara, Mauritania, Senegal, Mali, Burkina Fasso, Nigeria, Mali (again), and Algeria.

    研究了4个不同营养水平的(N、P营养充足、N限制、P限制和N、P双限制)大型海藻孔石莼(Ulva pertusa)对同样4个不同营养水平的海洋赤潮微藻赤潮异弯藻(Heterosigma akashiwo)的克制效果.不同的N、P营养状况能够显著影响孔石莼克制赤潮异弯藻的效果,N限制或P限制和N、P双限制下的孔石莼对赤潮异弯藻的克制作用减弱,N限制的赤潮异弯藻对孔石莼克生物质的耐受性增强,而P限制和N、P双限制的赤潮异弯藻对孔石莼的克生物质更加敏感.研究结果表明,不同营养状况下大型海藻对海洋微藻不同程度的克生作用可能是自然海洋生态系统中,N、P营养盐动态变化引起大型海藻和微藻种群动态变化的原因之一.%Allelopathic effectiveness of Viva pertusa of four different nutrient levels (N,P sufficient; N limitation; P limitation and N,P double limitation) on Heterosigma akashiwo of the same four different nutrient levels was investigated. Different N,P nutrient levels had significant influence on the effectiveness of allelopathic effect of Viva pertusa on Heterosigma akashiwo. The allelopathic effectiveness was decreased when Viva pertusa was under N or P limitation or N, P double limitation. Cells of Heterosigma akashiwo under N limitation were more tolerant to the macroalga, while mi-croalgal cells under P limitation or N, P double limitation were more sensitive to the macroalga. Different allelopathic effectiveness of macroalgae on microalgae under different nutrient levels may be one of the mechanisms that caused different population dynamics of macroalgae and microalgae during the change of N, P nutrient in coastal areas.

    以我国典型赤潮藻赤潮异弯藻(Heterosigma akashiwo)为研究对象,设置了6个浓度梯度(0 mg·L-1、0.001mg·L-1、0.01 mg·L-1、0.1 mg·L-1、1 mg·L-1和10 mg·L-1)的草甘膦异丙胺盐处理,研究了草甘膦异丙胺盐暴露对赤潮异弯藻的生长、叶绿素a含量和可溶性蛋白含量等指标的影响.结果表明,草甘膦异丙胺盐对赤潮异弯藻具有明显的毒性效应,10 mg·L-1浓度处理下,赤潮异弯藻细胞大量死亡,藻细胞密度以及叶绿素a、可溶性蛋白的含量显著降低(p<0.05);当草甘膦异丙胺盐浓度在0.001~1 mg·L-1范围内,在培养的第3d草甘膦异丙胺盐能够显著促进赤潮异弯藻的细胞密度增加,叶绿素a含量也明显高于对照组(p<0.05),表现出毒物刺激效应;在暴露实验的中后期(第7d、第9d和第11d),赤潮异弯藻的各生长指标均与对照无显著差异,可能是随着培养时间的延长,农药的降解、生物体对农药的适应、进入细胞的农药减少等原因,藻细胞生理状态逐渐恢复到正常水平.

  4. Response of antioxidant enzyme activities in Heterosigma akashiwo and Chattonella marina to lose-balance of N/P ratio%赤潮异弯藻和海洋卡盾藻抗氧化酶活性对氮磷比失衡的响应

    Institute of Scientific and Technical Information of China (English)

    王小冬; 王艳


    The antioxidanl enzymes of phytoplankton include CAT and SOD, which can alleviate the cellular oxidative damage by acmr-enging ROS species. The responses of activities of CAT, SOD in Heterosigma akashiwo and Chattonella marina to the nutrient limitation were investigated. The results showed that N-depletion depressed the growth and stimulated the activities of CAT and SOD in H. akashiwo and C. marina. The variation in the response of activities of SOD and CAT to the nutrition limitation was species-specific. The activities of SOD and CAT in H. akashiwo when exposed to the P-depletion were higher than N-depletion, however, both N-limi-tation and P-limitation insignificant impacted the activities of SOD and CAT in C. marina. The antioxidant enzymes apparently alleviate the potential damage caused by the nutrition limitation, thus the development and maintenance of harmful algae bloom need the help.%超氧化物歧化酶(SOD)和过氧化氢酶(CAT)是浮游植物抗氧化酶系统的重要组成部分,可有效消除因环境胁迫产生的活性氧自由基对细胞的损伤.本文通过研究氮磷比失衡状态下赤潮异弯藻和海洋卡盾藻的生长及其SOD与CAT酶活性的变化,探索了赤潮物种抗氧化酶对氮磷比失衡的响应.研究表明:N和P限制不仅抑制了赤潮异弯藻和海洋卡盾藻的生长,而且显著提高了SOD与CAT酶活性.酶活性对营养盐失衡的响应随营养盐类型和藻类种类不同而有所差异:赤潮异弯藻对P限制最为敏感,其SOD和CAT酶活性在P限制下显著高于N限制;而N限制和P限制对海洋卡盾藻抗氧化酶活性的影响并无差异.抗氧化酶活性的调控能够有效降低氮磷比失衡对藻类细胞的生理损伤,有利于藻华的发生和规模的维持.

    Full Text Available The scientific and technological developments during the 18th and' the 19th centuries ensured material progress of the West, as well as emergence of the West as the dominating power which colonized the rest of the world. During the post-colonial phase, Islam emerged as a revitalized sociopolitical force. This has been mistaken as a threat by the West, and Islam has been portrayed as the "new enemy after the demise of communism. This is partly an effort to establish a Western identity, which is disintegrating due to lack of a challenge; and partly a reflection of the failure of Muslims to realize the social and ethical ideals of Islam.

  20. West Candor Chasma (United States)


    During its examination of Mars, the Viking 1 spacecraft returned images of Valles Marineris, a huge canyon system 5,000 km long, up to 240 km wide, and 6.5 km deep, whose connected chasma or valleys may have formed from a combination of erosional collapse and structural activity. The view shows west Candor Chasma, one of the connected valleys of Valles Marineris; north toward top of frame. The image is a composite of Viking high-resolution (about 80 m/pixel or picture element) images in black and white and low resolution (about 250 m/pixel) images in color. The Viking 1 craft landed on Mars in July of 1976. West Candor Chasma occupies the westernmost part of the large west-northwest-trending trough of Candor Chasma. This section is about 150 km wide. West Candor Chasma is bordered on the north and south by straight-walled cliffs, most likely faults, and on its west by two segments of north-northeast-trending cliffs. The north wall is dissected by landslide scars forming reentrants filled with landslide debris. The south wall shows spur-and-gully morphology and smooth sections. The high-standing central mesa, informally dubbed Red Mesa has several curvilinear reentrants carved into the caprock, whose anomalously colored layers were interpreted to be caused by young hydrothermal alteration products (Geissler et al., 1993, Icarus, v. 106, p. 380-391). Light-colored lobes flow away from the top of the interior stack and then flow around and embay the same layered stack from which they originated. One of these apparent flow features is composed of at least two or perhaps even three huge, superposed, vaguely layered, very rugged, light-colored lobes as much as 100 km long, 20 km wide, and over 2 km thick. The layered deposits below the caprock also merge with a chaotic material that has local lobate fronts and overlaps landslide deposits. Hummocky material, similar in hue to wall rock, fills the southwestern-most region of west Candor Chasma and is perhaps as much as 3

  3. Drought in West Africa (United States)


    Drought settled over West Africa's Ivory Coast region when wet season rains came late in 2007. Instead of beginning in February, the rainy season didn't start until March, and steady rains didn't start until late March, said the Famine Early Warning System Network. Though the rain had started to alleviate the drought, vegetation was still depressed in parts of Cote d'Ivoire (Ivory Coast) between March 22 and April 6, 2007, when the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite captured the data used to make this image. The image shows current vegetation conditions compared to average conditions recorded since 2000. Areas where plants are growing more slowly or more sparsely than average are brown, while areas where vegetation is denser than average are green. The brown tint that dominates the image indicates that plants through most of the country are more sparse than normal. Among the crops affected by the lack of rain was West Africa's cocoa crop. About 70 percent of the world's cocoa comes from West Africa, and Cote d'Ivoire is a top grower, said Reuters. Cocoa prices climbed as the crop fell short. Farmers called the drought the worst in living memory, Reuters said. The delay in rainfall also led to water shortages in parts of Cote d'Ivoire, according to the United Nations Office for the Coordination of Humanitarian Affairs.

  4. West and Central Africa. (United States)

    Lydie, N; Robinson, N J


    This article reviews scientific and other literature during the 1990s that links migration and mobility with the spread of sexually transmitted diseases (STDs), including HIV/AIDS. The focus is on key population groups linked to the spread of HIV and STDs in West and Central Africa: migrant laborers, truck drivers, itinerant traders, commercial sex workers (CSWs), and refugees. Countries with high emigration and immigration tend to have high levels of HIV infection, with the exception of Senegal. The main destination of immigrants are Senegal, Nigeria, and Cote d'Ivoire in West Africa and Cameroon, Congo, Gabon, and Congo in Central Africa. The risk of infection and the spread of HIV is variable among migrants. There is little in the literature that substantiates hypotheses about the strong association between migration and HIV-positive status. Information is needed on the duration, frequency of return visits, living conditions, sexual activities with multiple partners, and information before departure, along the routes, at final destination, and at the time of returns. Action-based research in five West African countries (Burkina Faso, Cote d'Ivoire, Mali, Niger, and Senegal) should produce results in late 1998. Comparable studies in Central Africa are unknown. Regional studies should be complemented by local studies. Prevention would benefit from studies on the relative size of these five population groups by geographic location.

  8. [West Nile virus infection]. (United States)

    Pérez Ruiz, Mercedes; Gámez, Sara Sanbonmatsu; Clavero, Miguel Angel Jiménez


    West Nile virus (WNV) is an arbovirus usually transmitted by mosquitoes. The main reservoirs are birds, although the virus may infect several vertebrate species, such as horses and humans. Up to 80% of human infections are asymptomatic. The most frequent clinical presentation is febrile illness, and neuroinvasive disease can occur in less than 1% of cases. Spain is considered a high-risk area for the emergence of WNV due to its climate and the passage of migratory birds from Africa (where the virus is endemic). These birds nest surrounding wetlands where populations of possible vectors for the virus are abundant. Diagnosis of human neurological infections can be made by detection of IgM in serum and/or cerebrospinal fluid samples, demonstration of a four-fold increase in IgG antibodies between acute-phase and convalescent-phase serum samples, or by detection of viral genome by reverse transcription-polymerase chain reaction (especially useful in transplant recipients). Since WNV is a biosafety level 3 agent, techniques that involve cell culture are restricted to laboratories with this level of biosafety, such as reference laboratories. The National Program for the Surveillance of WNV Encephalitis allows the detection of virus circulation among birds and vectors in areas especially favorable for the virus, such as wetlands, and provides information for evaluation of the risk of disease in horses and humans.

  11. Landscape evolution of West Kunlun (United States)

    Wang, Bin; Chang, Hong


    Constituting the northwestern margin of the Tibetan Plateau, the present-day Western Kunlun is a spectacular mountain range, extending from the Pamir Plateau in the west to the Altyn Tagh fault and the Eastern Kunlun Range in the east. Dramatic climate variations have a significant control on the fluvial dissection, glacial erosion and wind transport. The West Kunlun Mountains is one of the key regions for understanding the uplift history of the Plateau and the climate change of Central Asia. The activities of tectonic and erosion make the topography of West Kunlun Mountains complex and varied. However, due to its remote location, there is still limited knowledge about the geomorphologic and geological features in West Kunlun Mountains .This paper tries to figure out the geomorphologic and geological features of this region qualitatively through studying the data of Shuttle Reader Topography Mission (SRTM) and topographic maps by digital elevation models (DEMs) and constructing profiles, aiming to make clear what functions the tectonics and climate exert on the topography of the West Kunlun Mountains. The West Kunlun Mountains, the northwestern margin of the Qinghai-Tibet Plateau, have strong tectonic activities. From south to north,West Kunlun Mountains developed three major faults: Kangxiwar fracture, North West Kunlun fault and Iron Creek fault. At about 25 Ma B.P., the West Kunlun began to uplift, and from about 5 Ma B.P., the West Kunlun began to grow rapidly. By using topographic analyzing software to make more than 10 vertical profiles across the main faults from south to north, it is obvious that there is a height difference between the upper and lower plate fracture, and the elevation of terrain profiles generally decreases from south to north. There is ~4,500m elevation difference between the main ridge of the West Kunlun Mountains out of Kangxiwar (5500-6000m) and the northern foot of the Tarim Basin (1200-1300m). The same progressively decreasing

  2. West Nile virus and "poliomyelitis". (United States)

    Sejvar, James J


    West Nile virus (WNV) has recently been associated with a syndrome of acute flaccid paralysis. Most cases of WNV-associated weakness have clinical, histopathologic, and electrophysiologic characteristics indistinguishable from those of poliomyelitis caused by infection with poliovirus. There is debate about the nomenclature of this manifestation of WNV infection. An historical perspective of the term "poliomyelitis" suggests that the term "WNV poliomyelitis" seems appropriate, but members of the neurologic and infectious disease communities should engage in discussion regarding the terminology of this syndrome.

  3. Surface winds over West Antarctica (United States)

    Bromwich, David


    Five winter months (April-August 1988) of thermal infrared satellite images were examined to investigate the occurrence of dark (warm) signatures across the Ross Ice Shelf in the Antarctic continent. These features are inferred to be generated by katabatic winds that descend from southern Marie Byrd Land and then blow horizontally across the ice shelf. Significant mass is added to this airstream by katabatic winds blowing from the major glaciers that flow through the Transantarctic Mountains from East Antarctica. These negatively buoyant katabatic winds can reach the northwestern edge of the shelf - a horizontal propagation distance of up to 1,000 km - 14 percent of the time. Where the airstream crosses from the ice shelf to the ice-covered Ross Sea, a prominent coastal polynya is formed. Because the downslope buoyancy force is near zero over the Ross Ice Shelf, the northwestward propagation of the katabatic air mass requires pressure gradient support. The study shows that the extended horizontal propagation of this atmospheric density current occurred in conjunction with the passage of synoptic cyclones over the southern Amundsen Sea. These cyclones can strengthen the pressure gradient in the interior of West Antarctica and make the pressure field favorable for northwestward movement of the katabatic winds from West Antarctica across the ice shelf in a geostrophic direction. The glacier winds from East Antarctica are further accelerated by the synoptic pressure gradient, usually undergo abrupt adjustment beyond the exit to the glacier valley, and merge into the mountain-parallel katabatic air mass.

  4. West Nile Virus and wildlife (United States)

    Marra, P.P.; Griffing, S.; Caffrey, C.; Kilpatrick, A.M.; McLean, R.; Brand, C.; Saito, E.; Dupuis, A.P.; Kramer, Laura; Novak, R.


    West Nile virus (WNV) has spread rapidly across North America, resulting in human deaths and in the deaths of untold numbers of birds, mammals, and reptiles. The virus has reached Central America and the Caribbean and may spread to Hawaii and South America. Although tens of thousands of birds have died, and studies of some bird species show local declines, few regionwide declines can be attributed to WNV. Predicting future impacts of WNV on wildlife, and pinpointing what drives epidemics, will require substantial additional research into host susceptibility, reservoir competency, and linkages between climate, mosquitoes, and disease. Such work will entail a collaborative effort between scientists in governmental research groups, in surveillance and control programs, and in nongovernmental organizations. West Nile virus was not the first, and it will not be the last, exotic disease to be introduced to the New World. Its spread in North America highlights the need to strengthen animal monitoring programs and to integrate them with research on disease ecology.

  10. West Nile virus and the climate. (United States)

    Epstein, P R


    West Nile virus is transmitted by urban-dwelling mosquitoes to birds and other animals, with occasional "spillover" to humans. While the means by which West Nile virus was introduced into the Americas in 1999 remain unknown, the climatic conditions that amplify diseases that cycle among urban mosquitoes, birds, and humans are warm winters and spring droughts. This information can be useful in generating early warning systems and mobilizing timely and the most environmentally friendly public health interventions. The extreme weather conditions accompanying long-term climate change may also be contributing to the spread of West Nile virus in the United States and Europe.

    Armenia is hosting the IAU South West Asian (SWA) Regional Office of Astronomy for Development (ROAD). It is a county of ancient astronomy and is also rich in modern astronomical facilities and infrastructures, hence may successfully serve as a regional center for various activities. Byurakan Astrophysical Observatory (BAO) has 2.6m and 1m Schmidt, as well as a number of smaller telescopes that are an observational basis for joint projects and collaborations. Armenian Virtual Observatory (ArVO) is hosting astronomical databases, such as the Digitized First Byurakan Survey (DFBS) and may also serve as a basis for development of VO structures in this region. Recently we have conducted a number of new activities; a meeting on ``Relation of Astronomy to other Sciences, Culture and Society" (RASCS) was organized by BAO and Armenian Astronomical Society (ArAS) in Oct 2014 in Byurakan. Activities related to Archaeoastronomy and Astronomy in Culture (AAC) were initiated as well. Discussions on future Armenian-Iranian collaboration in astronomy were carried out, including an Armenian-Iranian Astronomical Workshop held in Oct 2015 in Byurakan. Similar workshops have been carried out between BAO and Abastumani Astronomical Observatory (AbAO, Georgia) since 1974.

    Coal, the principal mineral resource of the Dolly Sods Wilderness, West Virginia is in at least seven beds of low- to medium-volatile bituminous rank. Of these beds, four are of sufficient thickness, quality, and extent to contain demonstrated coal resources which are estimated to total about 15. 5 million short tons in areas of substantiated coal resource potential. A Small-scale development of the coal resources of the Dolly Sods Wilderness has been by several shallow adits which provided fuel for locomotives during early logging operations and by a one truck mine. All mine entries are now abandoned. Peat, shale, clay, and sandstone, occur in the area but because of remoteness of markets and inaccessability they are not classified as resources in this report. Natural gas may occur in rocks underlying the area, but because of a lack of subsurface information an estimate of resource potential has not been made. No evidence of metallic-mineral resources was found during this investigation.

  13. West Nile Virus Drug Discovery

    Directory of Open Access Journals (Sweden)

    Siew Pheng Lim


    Full Text Available The outbreak of West Nile virus (WNV in 1999 in the USA, and its continued spread throughout the Americas, parts of Europe, the Middle East and Africa, underscored the need for WNV antiviral development. Here, we review the current status of WNV drug discovery. A number of approaches have been used to search for inhibitors of WNV, including viral infection-based screening, enzyme-based screening, structure-based virtual screening, structure-based rationale design, and antibody-based therapy. These efforts have yielded inhibitors of viral or cellular factors that are critical for viral replication. For small molecule inhibitors, no promising preclinical candidate has been developed; most of the inhibitors could not even be advanced to the stage of hit-to-lead optimization due to their poor drug-like properties. However, several inhibitors developed for related members of the family Flaviviridae, such as dengue virus and hepatitis C virus, exhibited cross-inhibition of WNV, suggesting the possibility to re-purpose these antivirals for WNV treatment. Most promisingly, therapeutic antibodies have shown excellent efficacy in mouse model; one of such antibodies has been advanced into clinical trial. The knowledge accumulated during the past fifteen years has provided better rationale for the ongoing WNV and other flavivirus antiviral development.

  4. Potential seaways across West Antarctica (United States)

    Vaughan, David G.; Barnes, David K. A.; Fretwell, Peter T.; Bingham, Robert G.


    The West Antarctic ice sheet (WAIS) has long been considered vulnerable to rapid retreat and today parts are rapidly losing ice. Projection of future change in WAIS is, however, hampered by our poor understanding of past changes, especially during interglacial periods that could be analogs for the future, but which undoubtedly provide an opportunity for testing predictive models. We consider how ice-loss would open seaways across WAIS; these would likely alter Southern Ocean circulation and climate, and would broadly define the de-glacial state, but they may also have left evidence of their existence in the coastal seas they once connected. We show the most likely routes for such seaways, and that a direct seaway between Weddell and Ross seas, which did not pass through the Amundsen Sea sector, is unlikely. Continued ice-loss at present rates would open seaways between Amundsen and Weddell seas (A-W), and Amundsen and Bellingshausen seas (A-B), in around one thousand years. This timescale indicates potential future vulnerability, but also suggests seaways may have opened in recent interglacial periods. We attempt to test this hypothesis using contemporary bryozoan species assemblages around Antarctica, concluding that anomalously high similarity in assemblages in the Weddell and Amundsen seas supports recent migration through A-W. Other authors have suggested opening of seaways last occurred during Marine Isotope Stage 7a (209 ka BP), but we conclude that opening could have occurred in MIS 5e (100 ka BP) when Antarctica was warmer than present and likely contributed to global sea levels higher than today.

  6. Evolution of the West Siberian Basin

    Energy Technology Data Exchange (ETDEWEB)

    The West Siberian Basin is one of the largest intra-cratonic basins of the world and an important hydrocarbon province of Russia. Perhaps the most important geologic event in Siberia was the emplacement of basalts around {approx} 250Ma (i.e. Permo-Triassic boundary) covering an area of about 5x10{sup 6} km{sup 2}. This volcanism may be responsible for a mass extinction that occurred around Permian-Triassic time. The pre-basaltic rifting event was limited to the north-northeastern sector of the basin. Initial basin wide subsidence took place in the Jurassic as a result of which the western part of Siberia became the West Siberian Basin bounded by uplifts to the east and to the west. One of the surprising aspects of the West Siberian Basin is the abundance of sub-vertical faults believed to be result of strike-slip movement. While intra-plate inversions and fault reactivation structures have been observed in many cratons, sub-vertical faults observed in the West Siberian Basin are unique because of their geometries and abundance. The differentiation between the effects of tectonics and eustasy in cratonic basins is simple-the global eustatic signal is basin-wide with regional and local tectonics playing an overprinting role. Thus, the Middle Jurassic-Turonian 1st, 2nd, and 3rd order cycles in the West Siberian Basin were primarily driven by eustasy. The Middle Jurassic-Turonian series can be subdivided into two second-order and 16 third-order transgressive-regressive cycles (within dataset extent). Fourth-order cycles appear to be controlled by delta shifting. Although extensively studied, a number of fundamental questions regarding the origin and evolution of the West Siberian Basin remain unresolved or poorly documented in the literature. [Author].

  10. Blooming Seas West of Ireland (United States)


    For several weeks in May and early June, daily satellite images of the North Atlantic Ocean west of Ireland have captured partial glimpses of luxuriant blooms of microscopic marine plants between patches of clouds. On June 4, 2007, the skies over the ocean cleared, displaying the sea's spring bloom in brilliant color. A bright blue bloom stretches north from the Mouth of the River Shannon and tapers off like a plume of blue smoke north of Clare Island. (In the large image, a second bloom is visible to the north, wrapping around County Donegal, on the island's northwestern tip.) The image was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite. Cold, nutrient-stocked water often wells up to the surface from the deeper ocean along coastal shelves and at the edges of ocean currents. When it does, it delivers a boost of nutrients that fuel large blooms of single-celled plants collectively known as phytoplankton. The plants are the foundation of the marine food web, and their proliferation in this area of the North Atlantic explains why the waters of western Ireland support myriad fisheries and populations of large mammals like seals, whales, and dolphins. Like plants on land, phytoplankton make their food through photosynthesis, harnessing sunlight for energy using chlorophyll and other light-capturing pigments. The pigments change the way light reflects off the surface water, appearing as colorful swirls of turquoise and green against the darker blue of the ocean. Though individually tiny, collectively these plants play a big role in Earth's carbon and climate cycles; worldwide, they remove about as much carbon dioxide from the atmosphere during photosynthesis as land plants do. Satellites are the only way to map the occurrence of phytoplankton blooms across the global oceans on a regular basis. That kind of information is important not only to scientists who model carbon and climate, but also to biologists and fisheries

We discovered cricket's importance in the English-speaking Caribbean nearly thirty years ago when we took up our first post in the West Indies. Exploring the Mona campus of the University of the West Indies, we were alarmed to observe so many people who appeared to be hearing-disabled. Wherever we went we found people with ear-pieces who were slightly distracted and at the same time prone to violent mood swings, ranging from the depths of despair to enormous elation. Uncertain about the meaning of what we observed, but reluctant, as newcomers, to reveal our ignorance of public health problems in the region, we delayed inquiring about hearing disabilities until we could confide our concerns to a trusted friend. At first convulsed with laughter, she finally recovered sufficiently to assure us that the people of the West Indies did not suffer disproportionately from hearing loss. Rather, the large numbers of people with ear-pieces were listening to a cricket test match!

In Inuktitut the tense......, and it is used when none of the others can be used. It seems that some of the tense suffixes i.e. past (-sima, perfective, perfect, preterite) and future (-ler, begin, be about to, near future) originally had a more or less concrete aspectual meanings and have developed into more abstract tense meanings...... suffixes have developed a complicated remoteness system. In West Greenlandic the future tense suffixes have a distinction between vague and inevitable future, and the past time suffixes have developed different perfect meanings. In Iñupiaq (Alaska), the temporal system is based on an opposition between...

  19. Vaccines in Development against West Nile Virus

    Directory of Open Access Journals (Sweden)

    Frederic Tangy


    Full Text Available West Nile encephalitis emerged in 1999 in the United States, then rapidly spread through the North American continent causing severe disease in human and horses. Since then, outbreaks appeared in Europe, and in 2012, the United States experienced a new severe outbreak reporting a total of 5,387 cases of West Nile virus (WNV disease in humans, including 243 deaths. So far, no human vaccine is available to control new WNV outbreaks and to avoid worldwide spreading. In this review, we discuss the state-of-the-art of West Nile vaccine development and the potential of a novel safe and effective approach based on recombinant live attenuated measles virus (MV vaccine. MV vaccine is a live attenuated negative-stranded RNA virus proven as one of the safest, most stable and effective human vaccines. We previously described a vector derived from the Schwarz MV vaccine strain that stably expresses antigens from emerging arboviruses, such as dengue, West Nile or chikungunya viruses, and is strongly immunogenic in animal models, even in the presence of MV pre-existing immunity. A single administration of a recombinant MV vaccine expressing the secreted form of WNV envelope glycoprotein elicited protective immunity in mice and non-human primates as early as two weeks after immunization, indicating its potential as a human vaccine.

  7. West Florida shelf upwelling: Origins and pathways (United States)

    Weisberg, Robert H.; Zheng, Lianyuan; Liu, Yonggang


    Often described as oligotrophic, the west Florida continental shelf supports abundant fisheries, experiences blooms of the harmful alga, Karenia brevis, and exhibits subsurface chlorophyll maxima evident in shipboard and glider surveys. Renewal of inorganic nutrients by the upwelling of deeper ocean water onto the shelf may account for this, but what are the origins and pathways by which such new water may broach the shelf break and advance toward the shoreline? We address these questions via numerical model simulations of pseudo-Lagrangian, isopycnic water parcel trajectories. Focus is on 2010, when the west Florida shelf was subjected to an anomalously protracted period of upwelling caused by Gulf of Mexico Loop Current interactions with the shelf slope. Origins and pathways are determined by integrating trajectories over successive 45 day intervals, beginning from different locations along the shelf break and at various locations and depths along the shelf slope. Waters upwelling across the shelf break are found to originate from relatively shallow depths along the shelf slope. Even for the anomalous 2010 year, much of this upwelling occurs from about 150 m and above, although waters may broach the shelf break from 300 m depth, particularly in the Florida Panhandle. Such interannual renewal of west Florida shelf waters appears to have profound effects on west Florida shelf ecology.

    Cotillon, Suzanne E.


    Started in 1999, the West Africa Land Use Dynamics project represents an effort to map land use and land cover, characterize the trends in time and space, and understand their effects on the environment across West Africa. The outcome of the West Africa Land Use Dynamics project is the production of a three-time period (1975, 2000, and 2013) land use and land cover dataset for the Sub-Saharan region of West Africa, including the Cabo Verde archipelago. The West Africa Land Use Land Cover Time Series dataset offers a unique basis for characterizing and analyzing land changes across the region, systematically and at an unprecedented level of detail.

  8. The Influence of the West in American Civil War

    Institute of Scientific and Technical Information of China (English)



    After the 19th century, the West was no longer an appendage of the South and the North. During the Civil War, the North had superiority in both economy and politics. This owed much to the West. The share of the same labour system laid the foundation of the union between the North and the West. The victory of the North linked closely to the support of the West. The essay analyzed the contribution made by the West from the perspectives of economy and politics.

  9. Tectonics in the Northwestern West Philippine Basin

    Institute of Scientific and Technical Information of China (English)

    Ni Xianglong; Wu Shiguo; Shinjo Ryuichi


    The West Philippine basin (WPB) is a currently inactive marginal basin belonging to Philippine Sea plate, which has a complex formation history and various crust structures. Based on gravity, magnetic and seismic data, the tectonics in West Philippine basin is characterized by amagnma spreading stage and strike slip fractures. NNE trending Okinawa-Luzon fracture zone is a large fracture zone with apparent geomorphology and shows a right-handed movement. The results of joint gravity-magnetic-seismic inversion suggest that the Okinawa-Luzon fracture zone has intensive deformation and is a transform fault. Western existence of the NW trending fractures under Ryukyu Islands Arc is the main cause of the differences between south and north Okinawa Trough. The Urdaneta plateau is not a remained arc, but remnant of mantle plume although its lava chemistry is similar to oceanic island basalt (OIB).

    Highlights: • The WEST project requires a set of three infrared diagnostics. • The tungsten divertor will be monitored by the existing diagnostic renewed. • The antennas monitoring require the development of an innovative diagnostic. • A fiber bundle will be used as image transport for the antennas monitoring. • A wide angle tangential view of the upper divertor and the first wall is studied. - Abstract: To operate long plasma discharge in tokamak equipped with actively cooled plasma facing components (PFC), infrared (IR) thermography is a key diagnostic. Indeed IR data are used for both PFC safety monitoring, to avoid material degradation and water leak, and various physics studies on plasma-wall interaction. The IR monitoring is becoming even more crucial with today metallic PFCs. This is the case for the WEST project (Tungsten (W) Environment for Steady State Tokamak), which aims at installing a W divertor in Tore Supra (TS), in order to operate the 1st tokamak with a full W actively cooled divertor in long plasma discharges. The IR thermography system for the WEST project described in this paper will consist of a set of 3 different diagnostics: (1) Six cameras located in upper ports viewing the full W divertor, which reuse a part of the existing diagnostic of TS. (2) Five novel views located behind the inner protection panels for the antennas monitoring, based on an innovative imaging fibers bundle technology. (3) A tangential wide angle view located in a median port, for the upper divertor and first wall monitoring.

  20. Cause of East-West Earth Asymmetry

    CERN Document Server

    Scalera, Giancarlo


    The different slope of the Wadati-Benioff zones oriented towards east and west is considered a main asymmetry of the Earth's globe. Under the Americas they have angles of about 30o, while under the Pacific east coasts (Asia, Japan) the angles are steeper. In the framework of plate tectonics geodynamics the cause of this difference can be identified in the tidal drag that would cause a global shift of the lithosphere towards west. But this solution has been many times criticized on the basis of the irrelevance of the tidal forces with respect to viscous friction. Instead, it is possible to show that in a different framework, in which sudden extrusions of mantle materials occur by local phase change toward a more unpacked lattice, the value of the Coriolis fictitious force can rise of several magnitude orders, becoming the main cause of the east-west asymmetry of the Wadati-Benioff zones, which might be ascribed entirely to internal causes of the planet (its rotation and geodynamics) and not to external causes ...

  2. Poverty and health in West Germany. (United States)

    Helmert, U; Mielck, A; Shea, S


    The relationship between poverty and several health-related characteristics in West Germany was investigated. Data were derived from the National and Regional Health Surveys conducted in West Germany from 1984 to 1992. 25,544 males and 25,719 females with German nationality aged 25-69 years were examined. Poverty was defined as a household income of 50% less than the mean for West Germany. Multiple logistic regression analysis was used to analyze the relationship between poverty and four health variables: individual health behavior, subjective assessment of health status, cardiovascular disease risk factors, and self-reported prevalence of lifetime chronic diseases. 10.2% of males and 12.8% of females were classified as being below the poverty line. For most but not all health parameters, less favourable results were found for the segment of the population with a household income below the poverty line. The most striking poverty-related differences were observed for lack of regular sport activities, subjective health satisfaction, obesity and myocardial infarction/stroke. Significantly lower prevalence rates for study subjects below the poverty line were observed for hypercholesterolemia in females only. Allergic disorders were the only chronic diseases reported significantly less often in males and females below the poverty line. Poverty has strong effects on individual health status and the prevalence of chronic diseases. Due to the rising unemployment rates in Germany in the last years it is very likely that the strong negative consequences of poverty for health are increasing.

    Highlights: • On Tokamaks, analogue integrators are key instruments. • Our analogue integrators is reliable and fast, thus relevant for fusion facilities. • Our integrator fulfils requirements for long time pulses of WEST Tokamak. • The performances are amongst the best never obtained for analogue integrators. - Abstract: The WEST project consists of implementing a divertor configuration in the Tore Supra Tokamak. This modification requires to renew the magnetic diagnostics and especially adding new magnetic sensors in the divertor region. This has provided an opportunity to consider some enhancements to the existing integrator modules of the magnetic diagnostics. Two prototypes have been produced using different combinations of technical solutions, aiming to achieve lower drift and higher common mode rejection ratio (CMRR). This paper presents the explored and tested ways we followed in order to create enhanced analogue integrators for long pulses. The results of extensive and comprehensive tests are summarized. The achieved performances are analyzed regarding the WEST project specifications and furthermore, the latest ITER requirements for magnetic diagnostics integrators are also considered.

  4. The ARM West Antarctic Radiation Experiment (AWARE) (United States)

    Lubin, Dan; Bromwich, David; Vogelmann, Andrew; Verlinde, Johannes; Russell, Lynn


    West Antarctica is one of the most rapidly warming regions on Earth, and its changing climate in both atmosphere and ocean is linked to loss of Antarctic ice mass and global sea level rise. The specific mechanisms for West Antarctic Ice Sheet (WAIS) warming are not fully understood, but are hypothesized to involve linkage between moisture from Southern Ocean storm tracks and the surface energy balance over the WAIS, and related teleconnections with subtropical and tropical meteorology. This present lack of understanding has motivated a climate science and cloud physics campaign jointly supported by the US National Science Foundation (NSF) and Department of Energy (DOE), called the Atmospheric Radiation Measurement Program (ARM) West Antarctic Radiation Experiment (AWARE). The DOE's second ARM Mobile Facility (AMF2) was deployed to McMurdo Station on Ross Island in November 2015 and will operate through December 2016. The AMF2 includes (1) cloud research radars, both scanning and zenith, operating in the Ka- and X-bands, (2) high spectral resolution and polarized micropulse lidars, and (3) a suite of shortwave and longwave broadband and spectral radiometers. A second suite of instruments is deployed at the WAIS Divide Ice Camp on the West Antarctic plateau during December 2015 and January 2016. The WAIS instrument suite provides (1) measurement of all surface energy balance components, (2) a polarized micropulse lidar and shortwave spectroradiometer, (3) microwave total water column measurement, and (4) four times daily rawinsonde launches which are the first from West Antarctica since 1967. There is a direct linkage between the WAIS instrument suite and the AMF2 at McMurdo, in that air masses originating in Southern Ocean storm tracks that are driven up over the WAIS often subsequently descend over the Ross Ice Shelf and arrive at Ross Island. Preliminary data are already illustrating the prevalence of mixed-phase clouds and their role in the surface energy balance

  7. Raw material studies of West Central Serbia

    Directory of Open Access Journals (Sweden)

    Vera Bogosavljević Petrović


    Full Text Available This paper deals with raw material problems in the territory of West Central Serbia geologically determined as the Čačak-Kraljevo (or West Morava basin. Our research is presented through the most striking case studies, Lojanik, Vlaška Glava and Lazac.  The Lojanik hill is a silicified forest by origin. It has occasionally been in use from the earliest periods of prehistory until today as a source of black and ochre-coloured flint, opal and silicified wood. A detailed prospection, including the mapping of surface finds using square nets, was conducted during two research campaigns.The Vlaška Glava is an open-air Palaeolithic site at which artefacts made of white, ochre, red, brown and black chert, silicified magnesite, volcanic and metamorphic rocks were found. Our research of primary and secondary geological deposits in the vicinity of the site showed equivalent raw material. We also found an interesting primary deposit of high quality bluish grey flint with outcrop activities (Workshop 1.The Lazac shaft is a contemporary magnesite mine, recently abandoned because of the high percentage of silicon-dioxide. We determined the same raw material in collections found at nearby Neolithic sites. Certain similarities between the wooden support systems of ore exploration in the Middle Ages and modern times were established at the entrance of the shaft.Our research in the territory of the West Morava basin resulted in reconstruction of some links between geological deposits and settlements and also creation of a relevant base for future raw material studies.

  8. West Edmonton Mall : buying into energy efficiency

    Energy Technology Data Exchange (ETDEWEB)

    Hanson, K. [West Edmonton Mall, AB (Canada)


    The West Edmonton Mall consists of 600 stores and services, as well as attractions including a marine life lagoon, a skating rink, the largest indoor wave pool in the world, and an amusement park. Lighting retrofits, power-factor correction equipment, and tenant energy-saving criteria all combine to make the West Edmonton Mall a model of energy efficiency. An energy consultant was hired in 2001 to develop an energy management plan in an attempt to find ways to save energy while providing a return on investment. Reduction in greenhouse gas emissions are a consequence of reduced energy consumption. Variable frequency drives (VFDs) were recently installed on heating ventilation and air conditioning (HVAC) fans, with assistance from the Energy Innovators Initiative (EII) of Natural Resources Canada. In addition, the West Edmonton Mall is now signed up with Canada's Climate Change Voluntary Challenge and Registry Inc. The retrofit involved the conversion of 42 constant speed, variable-pitch supply and return fans to a fixed pitch. The total cost of the retrofit was $970,000, and the energy savings are expected to reach $524,295 annually. A brief overview of energy savings measures implemented since 1985 was provided. Separate metering and billing for new tenants is a strategy to make sure that they are aware of their energy costs. This strategy makes them more active in reducing their energy consumption. An awareness and accountability system was put in place, and a variety of potential projects are being evaluated, such as a cogeneration system, updating fluid pumps, and adding new controls to hot water heaters. 1 tab.

    To operate advanced plasma scenario (long pulse with high stored energy) in present and future tokamak devices under safe operation conditions, the control requirements of the plasma control system (PCS) leads to the development of advanced feedback control and real time handling exceptions. To develop these controllers and these exceptions handling strategies, a project aiming at setting up a flight simulator has started at CEA in 2009. Now, the new WEST (W Environment in Steady-state Tokamak) project deals with modifying Tore Supra into an ITER-like divertor tokamak. This upgrade impacts a lot of systems including Tore Supra PCS and is the opportunity to improve the current PCS architecture to implement the previous works and to fulfill the needs of modern tokamak operation. This paper is dealing with the description of the architecture of WEST PCS. Firstly, the requirements will be presented including the needs of new concepts (segments configuration, alternative (or backup) scenario, …). Then, the conceptual design of the PCS will be described including the main components and their functions. The third part will be dedicated to the proposal RT framework and to the technologies that we have to implement to reach the requirements.

  9. [Epidemics and colonial medicine in West Africa]. (United States)

    Becker, C; Collignon, R


    We studied colonial medical practices and health policies in West Africa, which has faced endemics and epidemics that have affected entire societies. We found that attempts to centralize the organization of colonial medicine, which began in the late 19th Century, were limited until the end of World War I. Research and control programs expanded after 1920, concentrating on epidemics, but largely ignoring many major health problems, such as measles, whooping cough and malnutrition, the importance of which were not recognized until after World War II. This appraisal of colonial medicine highlights the difficulties of introducing modern medicine and its ideas into African societies. There have been various social reactions, resulting in the current duality in which traditional and modern medicine coexist.

    Subsidence monitoring is a critical component to understanding the cavern integrity of salt storage caverns. This report looks at historical and recent data from two of the three West Hackberry dome cavern operators. DOE SPR and LA Storage are coordinating subsidence surveys to create a comprehensive understanding of ground movement above the dome. Data from annual level and rod surveys, GPS, and tiltmeter data show the sites are experiencing typical ground movement. The highest subsidence rate is seen in the middle of the DOE SPR site at just under one inch per year with less ground movement around the edge of the site. A GPS and tiltmeter instrument in the northeast areas of the DOE SPR site has not seen any trend change since the devices were installed in 2013. Comparison between recent ground movement data and historical trends suggest that there is no reason to believe that any DOE SPR or LA Storage caverns have been structurally compromised.

    China is under increasingly severe criticism from the West for its environ- menial problems,but recently there are varying voices in the international community about the reasons surrounding this issue.According to Britain’s New Economics Foundation,Western countries rely heavily on Chinese commodities,meaning in the process of manufacturing they are transferring pollution to China.This London-based think tank also puts forward that the discussion should shift its focus from commodity producers to consumers. Writing in the Economic Observer,Professor Hou Dongmin from the Center for Population and Development Studies under the Renmin University of China says that the international community has to face up to the truth.He believes one of the reasons for environmental pollution in China is the country is undertaking a high proportion of global manufacturing activities,which naturally brings environmental pressure to China.Excerpts of Hou’s thoughts follow:

    Human activities have greatly increased nitrogen emissions and deposition across large areas of Earth. Although nitrogen is an essential nutrient for plant growth, too much nitrogen in excess of critical loads leads to losses of biodiversity, soil and stream acidification, nutrient imbalances, and other deleterious effects. In a new report quantifying critical loads of nitrogen deposition across the United States, USGS scientist Steve Perakis and co-authors provided a chapter about responses of marine west coast forests. Much of this region is understudied with respect to nitrogen deposition, and in this chapter the authors identify known adverse effects and estimate critical loads of nitrogen deposition for western Oregon and Washington and southeast Alaska forests. Perakis also contributed to the synthesis chapter, which includes background, objectives, advantages and uncertainties of critical loads, an overview of critical loads across U.S. ecoregions, and other topics.

  18. West Nile Disease Epidemiology in North-West Africa: Bibliographical Review. (United States)

    Benjelloun, A; El Harrak, M; Belkadi, B


    West Nile fever (WNF) or West Nile disease (WND) is a mosquito-borne viral disease that can affect birds, humans and horses. West Nile virus (WNV) is a member of the genus Flavivirus in the family Flaviviridae. WNV is maintained in a mosquito-bird-mosquito transmission cycle, whereas humans and horses are considered dead-end hosts. In human and horses, symptoms range from unapparent infection to mild febrile illness, meningitis, encephalitis or death. WNV has a wide geographical range that includes portions of Europe, Asia, Africa, Australia (Kunjin virus), and in North, Central and South America. Migratory birds are thought to be primarily responsible for virus dispersal, including reintroduction of WNV from endemic areas into regions that experience sporadic outbreaks (Fields Virology, 2001, Lippincott Williams and Wilkins, Philadelphia, Pennsylvania, USA, 1043-1125). The occurrence of disease in humans and animals along with birds and mosquitoes surveillance for WNV activity demonstrates that the virus range has dramatically expanded including North, Central and South America as well as Europe and countries facing the Mediterranean Basin. WND infection in humans has been reported in Morocco in 1996 (Virologie, 1, 1997, 248), in Tunisia in 2007 (Ann. N. Y. Acad., 951, 2001, 117) (Med. Trop., 61, 2001, 487) and 2003 (Epidémiologie de la fièvre West Nile, 2012, Thèse de doctorat, Université Montpellier II, Sciences et techniques du Langueduc, Montpellier, France), and in Algeria in 1994 (Rev. Sci. Tech., 31, 2012, 829). Outbreaks of equine encephalitis have been also reported in Morocco in 1996 (Bull. OIE, 11, 1996, 867), in 2003 (Emerg. Infect. Dis., 11, 2005, 306) and in 2010 (World Animal Health Information Database. WAHID, 2010). Serological evidence of WNV has been demonstrated in the three countries in many species. The aim of this review was to assess the epidemiological situation of WND in north-west Africa comprising Morocco, Algeria and Tunisia, with

  19. Rural poverty and development in West Malaysia. (United States)

    Peacock, F


    Rural poverty in West Malaysia during the 1957-1970 period is examined. The period covered was 1 of a high rate of growth combined with an increasing inequality of income and worsening poverty. During the 1955-1970 period, a large amount of development funds, manpower, and expertise was directed towards a reduction of West Malaysia's rural poverty. Despite these efforts, rural poverty increased. Over the period under review, the share of income going to the richest 20% of the population increased from 50% to 56%; the share going to the middle 20% of the population remained constant at 20%; the poorest 60% of the population saw their share of income decline from 30% to 24%. The poorest 40% of the population received only 11.6% of income in 1970. They were predominantly rural, with this sector accounting for 87% of all poverty. The 3 development plans of this period set high aggregate growth rates as the primary targets and emphasized productivity and income in the rural sector. Rural development has not been sold short; the total funding figure of $2,209.46 million represents 40% of all development spending between 1956 and 1970. The money funded 3 broad areas of rural development: replanting of smallholder rubber with high-yielding clones; increasing rice production; and opening new land. The strategy has been to concentrate upon raising the yields from existing farmland and expanding into new areas of settlement. The problem of dealing with poverty in West Malaysia was made worse by the rapid rate of population increase. The population increase of 1,657,000 was absorbed into the traditional smallholder sector, very largely in exisitng areas of settlement. Over the same period, the modern sector of agriculture, the rubber estates, reduced their labor force by 30,000 as they moved into the cultivation of oil palm, a crop requiring less labor. Some of the additional agricultural workers were placed on new land under government land-development and resettlement

  20. Passive solar systems performance in West Germany

    Energy Technology Data Exchange (ETDEWEB)

    Habenicht, G.


    This paper discusses the influence of the two main climatic features (solar radiation and temperature) on the performance of passive solar systems in West Germany. Evaluations were made for the four climatic zones - German Lowlands, German Highlands, Alp Foreland, Alps. These zones differ in solar radiation, temperature and diurnal temperature swings. To evaluate different passive solar systems (direct gain, Trombe wall, water wall) a prototypical dwelling was designed which responded to the environmental conditions. The calculations of the ''Solar Savings Fraction'' (SSF) of each systems were made with a program based on the 'LCR-method'. The paper concludes that although the heating requirements decrease with decreasing latitude and altitude, the SSF is nearly the same for all parts of Germany. They are in a range of +- 5%. This is due to the fact that two main climatic features solar radiation and temperature balance each other. In northern Germany the man solar radiation level is low and so is the number of heating degree days. The conditions in southern Germany are reverse.

    Full Text Available Rendell stated that gender representation underlined the production of space in architecture both symbolically and functionally in certain cultures (Rendell et al. 2000. Thus, an exploration on the spatial functionality of traditional houses could show how cultural gender rules and roles generate the spatial arrangements. This empirical research explored the traditional houses in two kampongs: Tarung and Ratenggaro of West Sumba, Indonesia, which spaces are divided into two distinct spaces: male’s space and female’s space, each with its own entrance. This firm division leads to the questions on its relation with the traditional gender roles are represented inside the house. Interestingly, the spatial arrangement is not intended to create separation between men and women inside the house or to pose that the status and roles of men are higher than those of women. The research found that the space separation actually is a manifestation of the dynamic roles of male and female members of the house and the circular arrangement of the space around the fireplace at the centre of the house follows the dynamic of gender duality in Sumba culture.

  2. West Royalty substation fire post mortem

    Energy Technology Data Exchange (ETDEWEB)



    This post mortem discussed a fire that occurred as a result of three 13.8 kV circuit breakers tripping at a substation control building in Prince Edward Island (PEI). Employees of the electric utility were immediately dispatched to the substation. Between 25,000 and 55,000 customers were without power as a result of firefighters tripping the 138 kV supply to the substation in order to disconnect electricity from the building. A 55 MW combustion turbine was black-started by the operator in order to pick up the electrical load from the Charlottetown substation. Power was gradually restored to utility customers in the region over the next day. An additional generator was used to supply electricity to a final few customers in outlying areas. A subsequent investigation determined that a squirrel caused the breaker to trip. However, a fault in the breaker caused the outage to become more widespread. The utility will continue to investigate methods of improving pest control for substation buildings. A new 13.8 kV circuit will be built to interconnect the Charlottetown and West Royalty substations. 1 fig.

  3. William Wilde in the West of Ireland. (United States)

    Coakley, D


    It is widely believed that Sir William Wilde's forebears were in Ireland for just two or three generations. This belief stems from a number of short biographies of Wilde which were published during his lifetime. These biographies gave different versions of the origin of the Wilde family and appear to have been generated by the creative imagination of Lady Jane Wilde or, as she was better known by her nom de plume, Speranza. She was equally imaginative in creating narratives about her own family background and in one she claimed descent from the Italian poet Dante Alighieri. So it was not a great challenge for her to invent biographies of her husband which she deemed suitable for a knight living at the prestigious address of 1 Merrion Square, leading many to believe that William and his son Oscar were more English than Irish. It was also important for Speranza to distance Sir William from any connection which the Wilde family might have had with trade. In this paper published and unpublished material are used, together with a careful examination of family deeds in the Registry of Deeds office, to elucidate the real roots of the Wilde family in Dublin and in the West of Ireland.

  4. Deglacial temperature history of West Antarctica (United States)

    Cuffey, Kurt M.; Clow, Gary D.; Steig, Eric J.; Buizert, Christo; Fudge, T. J.; Koutnik, Michelle; Waddington, Edwin D.; Alley, Richard B.; Severinghaus, Jeffrey P.


    The most recent glacial to interglacial transition constitutes a remarkable natural experiment for learning how Earth’s climate responds to various forcings, including a rise in atmospheric CO2. This transition has left a direct thermal remnant in the polar ice sheets, where the exceptional purity and continual accumulation of ice permit analyses not possible in other settings. For Antarctica, the deglacial warming has previously been constrained only by the water isotopic composition in ice cores, without an absolute thermometric assessment of the isotopes’ sensitivity to temperature. To overcome this limitation, we measured temperatures in a deep borehole and analyzed them together with ice-core data to reconstruct the surface temperature history of West Antarctica. The deglacial warming was 11.3±1.8∘11.3±1.8∘C, approximately two to three times the global average, in agreement with theoretical expectations for Antarctic amplification of planetary temperature changes. Consistent with evidence from glacier retreat in Southern Hemisphere mountain ranges, the Antarctic warming was mostly completed by 15 kyBP, several millennia earlier than in the Northern Hemisphere. These results constrain the role of variable oceanic heat transport between hemispheres during deglaciation and quantitatively bound the direct influence of global climate forcings on Antarctic temperature. Although climate models perform well on average in this context, some recent syntheses of deglacial climate history have underestimated Antarctic warming and the models with lowest sensitivity can be discounted.

  5. Attenuation tomography in West Bohemia/Vogtland (United States)

    Mousavi, Sima; Haberland, Christian; Bauer, Klaus; Hejrani, Babak; Korn, Michael


    We present a three-dimensional (3-D) P-wave attenuation (Qp) model for the geodynamically active swarm earthquake area of West Bohemia/Vogtland in the Czech/German border region. Path-averaged attenuation t* is calculated from amplitude spectra of time windows around the P-wave arrivals of local earthquakes. Average t/t* value or Qp for stations close to Nový Kostel are very low (focal zone (increases up to 500 within 80 km distance). The SIMUL2000 tomography scheme is used to invert the t* for P-wave attenuation perturbation. Analysis of resolution shows that our model is well-resolved in the vicinity of earthquake swarm hypocenters. The prominent features of the model are located around Nový Kostel focal zone and its northern vicinity. Beneath Nový Kostel a vertically stretched (down to depth of 11 km) and a highly attenuating body is observed. We believe that this is due to fracturing and high density of cracks inside the weak earthquake swarm zone in conjunction with presence of free gas/fluid. Further north of Nový Kostel two highly attenuating bodies are imaged which could represent fluid channels toward the surface. The eastern anomaly shows a good correlation with the fluid accumulation area which was suggested in 9HR seismic profile.

  6. [West Nile virus: a reality in Mexico]. (United States)

    Téllez, Ildefonso; Calderón, Oscar; Franco-Paredes, Carlos; del Río, Carlos


    West Nile virus (WNV) is a RNA virus of the Flaviridae, genus flavivirus family. It is a neuropathogenic virus causing disease in birds, horses and humans. WNVis transmitted by the vector mosquito Culex sp. The virus life 's cycle includes mosquitoes as vectors and birds as natural hosts. Humans are accidental hosts. Since the introduction of the Epidemiological Surveillance Program at the Ministry ofHealth. we have documented 90 positive test results among birds out of 1,223 cases studied in Mexico as of September IS. 2005. The incubation period in humans after a mosquito bite ranges from 3 to 14 days. Disease is characterized by early onset fever, general malaise, decreased appetite, nausea, vomiting, headaches, myalgias, enlarged lymph nodes andrash. Neurological manifestations include encephalitis andflaccid paralysis, which are present in less than 1% of subjects infected with WNV. Older patients display more adverse outcomes including death. The diagnosis is made by the determination of specific IgM and JgG antibodies in serum and/or cerebrospinal fluid. There is no antiviral treatment to date against WNV but interferon ?2b, and WNVspec4ic-immunoglobulin have been used Prevention is therefore the key to control the infection.

  7. Happy Environments: Bhutan, Interdependence and the West

    Directory of Open Access Journals (Sweden)

    Randy Schroeder


    Full Text Available There is a growing trend to understand economic and environmental policies in terms of multiple dimensions and “interdependence.” Bhutan is increasingly seen as an operational model with its Gross National Happiness (GNH strategy. GNH, which is rooted in Mahayana Buddhism, is a framework and set of policy tools that conceptualizes sustainability as interdependent ecological, economic, social, cultural and good governance concerns. Bhutan’s practical GNH experience illustrates a significant ability to positively couple economic growth with a healthy environment. Can the “West”—with its legacy of either/or economics—learn anything from Bhutan’s multidimensional policy experiment? At first, it would seem not. It is questionable whether the West can replicate Bhutan’s unorthodox policy tools as we do not have a balancing set of Buddhist values rooted in mainstream culture. We are not equipped to respond to the many unintended consequences of interdependent policy because we do not yet understand what “interdependence” actually entails. There is hope, but much of it exists in the grey literature of ecological economics. This literature is in urgent need of greater exposure if we are to imagine and enact sustainability policy tools that are truly sensitive to interdependence, and thus follow Bhutan on its perilous but necessary journey.

    Full Text Available For the purpose of this article, the analysis of the development of ethnoseparatism in West Europe has been undertaken. Under current conditions, the ethnical separatism threatens national security of series of European countries and territorial integrity. Special attention has been paid to social and political beginnings and causes of terrorism in Spain and Great Britain. The activity of such terrorist organizations as IRA and ETA has been researched. Ideological basis of violence, purposes and objectives, as well as the main stages of formation and development of these organizations have been disclosed. The author states that the use of the terrorism as a method of political struggle is destructive and does not facilitate a solution to the national problems. We have also considered approaches of the governments to solve the problems of separatism and terrorism on the territory of these countries. In their counter-terrorism efforts political leaders of Spain and Great Britain have used both methods of force and political and legal methods, namely, granting to the regions of wide economical and political independence, preservation of authentic cultural values and language of indigenous people. The formation of violence intolerance in public conscience as control method has become the main direction of the antiterrorist policy in the countries under consideration. Anti-terrorist model which has been developed by the European countries can be effective and useful for the regions being in ethnopolitical conflicts

To answer these questions, the U.S. Geological Survey West Africa Land Use Dynamics project partnered with the Permanent Interstate Committee for Drought Control in the Sahel and the U.S. Agency for International Development/West Africa to map land use and land cover across the region for  three time periods (years): 1975, 2000, and 2013. This cooperative effort has resulted in the publication of a 219-page atlas, “Landscapes of West Africa: A Window on a Changing World.” The atlas uses satellite imagery, maps, and pictures to tell a complex story of landscape change at regional and national scales. It includes a collection of focused studies, some of which raise cause for concern, and others that provide considerable hope.

  8. Markets, Climate Change and Food Security in West Africa (United States)

    Brown, Molly E.; Hintermann, Beat; Higgins, Nathaniel


    West Africa is one of the most food insecure regions of the world. Sharply increased food and energy prices in 2008 brought the role of markets in food access and availability around the world into the spotlight, particularly in urban areas. The period of high prices had the immediate consequence of sharply increasing the number of hungry people in the region without boosting farmer incomes significantly. In this article, the interaction between markets, food prices, agricultural technology and development is explored in the context of West Africa. To improve food security in West Africa, sustained commitment to investment in the agriculture sector will be needed to provide some protection against global swings in both production and world markets. Climate change mitigation programs are likely to force global energy and commodity price increases in the coming decades, putting pressure on regions like West Africa to produce more food locally to ensure stability in food security for the most vulnerable.

    West Nile virus is an arbovirus that has caused large outbreaks of febrile illness, meningitis and encephalitis in Europe, North America and the Middle East. We describe the first laboratory-confirmed human case of West Nile virus infection in Australia, in a 58-year-old tourist who was almost certainly infected in Israel. The case is a reminder of the need to consider exotic pathogens in travellers and of the risk of introducing new pathogens into Australia.

  16. A Regional Approach to Market Monitoring in the West

    Energy Technology Data Exchange (ETDEWEB)

    Barmack, Matthew; Kahn, Edward; Tierney, Susan; Goldman, Charles


    Market monitoring involves the systematic analysis of pricesand behavior in wholesale power markets to determine when and whetherpotentially anti-competitive behavior is occurring. Regional TransmissionOrganizations (RTOs) typically have a market monitoring function. Becausethe West does not have active RTOs outside of California, it does nothave the market monitoring that RTOs have. In addition, because the Westoutside of California does not have RTOs that perform centralized unitcommitment and dispatch, the rich data that are typically available tomarket monitors in RTO markets are not available in the West outside ofCalifornia. This paper examines the feasibility of market monitoring inthe West outside of California given readily available data. We developsimple econometric models of wholesale power prices in the West thatmight be used for market monitoring. In addition, we examine whetherproduction cost simulations that have been developed for long-runplanning might be useful for market monitoring. We find that simpleeconometric models go a long ways towards explaining wholesale powerprices in the West and might be used to identify potentially anomalousprices. In contrast, we find that the simulated prices from a specificset of production cost simulations exhibit characteristics that aresufficiently different from observed prices that we question theirusefulness for explaining price formation in the West and hence theirusefulness as a market monitoring tool.

  17. The 1983 drought in the West Sahel: a case study

    Bader, Juergen [Bjerknes Centre for Climate Research, Bergen (Norway); University of Bergen, Geophysical Institute, Bergen (Norway); Latif, Mojib [Leibniz-Institute for Marine Sciences at the University of Kiel, Kiel (Germany)


    Some drought years over sub-Saharan west Africa (1972, 1977, 1984) have been previously related to a cross-equatorial Atlantic gradient pattern with anomalously warm sea surface temperatures (SSTs) south of 10 N and anomalously cold SSTs north of 10 N. This SST dipole-like pattern was not characteristic of 1983, the third driest summer of the twentieth century in the Sahel. This study presents evidence that the dry conditions that persisted over the west Sahel in 1983 were mainly forced by high Indian Ocean SSTs that were probably remanent from the strong 1982/1983 El Nino event. The synchronous Pacific impact of the 1982/1983 El Nino event on west African rainfall was however, quite weak. Prior studies have mainly suggested that the Indian Ocean SSTs impact the decadal-scale rainfall variability over the west Sahel. This study demonstrates that the Indian Ocean also significantly affects inter-annual rainfall variability over the west Sahel and that it was the main forcing for the drought over the west Sahel in 1983.

  18. Sequestration Options for the West Coast States

    Energy Technology Data Exchange (ETDEWEB)

    Myer, Larry


    The West Coast Regional Carbon Sequestration Partnership (WESTCARB) is one of seven partnerships that have been established by the U.S. Department of Energy (DOE) to evaluate carbon capture and sequestration (CCS) technologies best suited for different regions of the country. The West Coast Region comprises Arizona, California, Nevada, Oregon, Washington, Alaska, and British Columbia. Led by the California Energy Commission, WESTCARB is a consortium of about 70 organizations, including state natural resource and environmental protection agencies; national laboratories and universities; private companies working on carbon dioxide (CO{sub 2}) capture, transportation, and storage technologies; utilities; oil and gas companies; nonprofit organizations; and policy/governance coordinating organizations. Both terrestrial and geologic sequestration options were evaluated in the Region during the 18-month Phase I project. A centralized Geographic Information System (GIS) database of stationary source, geologic and terrestrial sink data was developed. The GIS layer of source locations was attributed with CO{sub 2} emissions and other data and a spreadsheet was developed to estimate capture costs for the sources in the region. Phase I characterization of regional geological sinks shows that geologic storage opportunities exist in the WESTCARB region in each of the major technology areas: saline formations, oil and gas reservoirs, and coal beds. California offers outstanding sequestration opportunities because of its large capacity and the potential of value-added benefits from enhanced oil recovery (EOR) and enhanced gas recovery. The estimate for storage capacity of saline formations in the ten largest basins in California ranges from about 150 to about 500 Gt of CO{sub 2}, the potential CO{sub 2}-EOR storage was estimated to be 3.4 Gt, and the cumulative production from gas reservoirs suggests a CO{sub 2} storage capacity of 1.7 Gt.

  20. Neuromuscular Manifestations of West Nile Virus Infection

    Directory of Open Access Journals (Sweden)

    A. Arturo eLeis


    Full Text Available The most common neuromuscular manifestation of West Nile virus (WNV infection is a poliomyelitis syndrome with asymmetric paralysis variably involving one (monoparesis to four limbs (quadriparesis, with or without brainstem involvement and respiratory failure. This syndrome of acute flaccid paralysis may occur without overt fever or meningoencephalitis. Although involvement of anterior horn cells in the spinal cord and motor neurons in the brainstem are the major sites of pathology responsible for neuromuscular signs, inflammation also may involve skeletal or cardiac muscle (myositis, myocarditis, motor axons (polyradiculitis, peripheral nerve (Guillain-Barré syndrome, brachial plexopathy. In addition, involvement of spinal sympathetic neurons and ganglia provides a plausible explanation for autonomic instability seen in some patients. Many patients also experience prolonged subjective generalized weakness and disabling fatigue. Despite recent evidence that WNV may persist long term in the central nervous system or periphery in animals, the evidence in humans is controversial. WNV persistence would be of great concern in immunosuppressed patients or in those with prolonged or recurrent symptoms. Support for the contention that WNV can lead to autoimmune disease arises from reports of patients presenting with various neuromuscular diseases that presumably involve autoimmune mechanisms (GBS, other demyelinating neu¬ropathies, myasthenia gravis, brachial plexopathies, stiff-person syndrome, and delayed or recurrent symptoms. Although there is no specific treatment or vaccine currently approved in humans, and the standard remains supportive care, drugs that can alter the cascade of immunobiochemical events leading to neuronal death may be potentially useful (high-dose corticosteroids, interferon preparations, and intravenous immune globulin containing WNV-specific antibodies. Human experience with these agents seems promising based on anecdotal

  1. Contaminants in two West Greenland caribou populations

    Energy Technology Data Exchange (ETDEWEB)

    Gamberg, Mary, E-mail: [Gamberg Consulting, 708 Jarvis St., Whitehorse, Yukon Y1A 2J2 (Canada); Cuyler, Christine [Greenland Institute of Natural Resources, PO Box 570, 3900 Nuuk, Greenland (Denmark); Wang, Xiaowa [Environment Canada, 867 Lakeshore Rd., Burlington, ON L7S 1A1 (Canada)


    Two caribou populations in West Greenland were sampled and the kidneys, liver and muscle analyzed for contaminants, including aluminum, arsenic, cadmium, copper, lead, mercury, selenium and zinc. Although close in proximity, the two populations are topographically separated by an ice cap, which creates different climates and vegetation types in each region. Contaminant levels reflected the differing diets of the two caribou populations. To the south in the wetter lichen-rich region, caribou had significantly more aluminum, arsenic, cadmium, lead, mercury, selenium and zinc, likely due to atmospheric deposition on lichens. To the north in the dry desert steppe where grasses predominate, caribou had higher levels of copper. Cows collected in late winter had significantly less hepatic copper, lead and mercury if pregnant, indicating placental transfer of these elements. Our results suggest that hepatic copper levels < 200 μg g{sup −1} dry weight may result in copper depletion in pregnant cows and hepatic mercury concentrations above 0.5 μg g{sup −1} dry weight may negatively affect fertility in caribou cows. Hepatic mercury levels were negatively correlated with cow body weight, suggesting an adverse effect on body condition. Element concentrations found in tissues from these caribou are not considered to be of a health concern for those consuming this traditional food. - Highlights: • Caribou tissue contaminant profiles may reflect different diets. • Low hepatic copper may result in copper depletion in pregnant caribou. • High hepatic mercury may negatively affect fertility in caribou cows. • Hepatic mercury is negatively correlated with body condition in caribou cows. • Metal levels in tissues are not a health concern to people consuming caribou.

  2. Analysis of K west basin canister gas

    Energy Technology Data Exchange (ETDEWEB)

    Trimble, D.J., Fluor Daniel Hanford


    Gas and Liquid samples have been collected from a selection of the approximately 3,820 spent fuel storage canisters in the K West Basin. The samples were taken to characterize the contents of the gas and water in the canisters providing source term information for two subprojects of the Spent Nuclear Fuel Project (SNFP) (Fulton 1994): the K Basins Integrated Water Treatment System Subproject (Ball 1996) and the K Basins Fuel Retrieval System Subproject (Waymire 1996). The barrels of ten canisters were sampled for gas and liquid in 1995, and 50 canisters were sampled in a second campaign in 1996. The analysis results from the first campaign have been reported (Trimble 1995a, 1995b, 1996a, 1996b). The analysis results from the second campaign liquid samples have been documented (Trimble and Welsh 1997; Trimble 1997). This report documents the results for the gas samples from the second campaign and evaluates all gas data in terms of expected releases when opening the canisters for SNFP activities. The fuel storage canisters consist of two closed and sealed barrels, each with a gas trap. The barrels are attached at a trunion to make a canister, but are otherwise independent (Figure 1). Each barrel contains up to seven N Reactor fuel element assemblies. A gas space of nitrogen was established in the top 2.2 to 2.5 inches (5.6 to 6.4 cm) of each barrel. Many of the fuel elements were damaged allowing the metallic uranium fuel to be corroded by the canister water. The corrosion releases fission products and generates hydrogen gas. The released gas mixes with the gas-space gas and excess gas passes through the gas trap into the basin water. The canister design does not allow canister water to be exchanged with basin water.

  4. Islam, Islamophobia and the West: Opposing Views and Social Reality

    Directory of Open Access Journals (Sweden)

    Adila Pavelić


    Full Text Available Through reviewing different and often opposing views on the relationship between Islam and the West, the paper aims to offer a better understanding of this relationship, and of Islamophobia as an old, yet increasingly actual and in many respects relevant social problem. A short historical overview of the understanding of the relationship between Islam and the West, and various definitions of Islamophobia, are followed by examination of some recent works that from different perspectives deal with the issue. Firstly, is given insight into the works written by Western theorists who describe the relationship between Islam and the West within the framework of the idea of the clash of civilizations while, at the same time, labeling Islam often as a non-modern religion and culture whose members reject Western values such as democracy, freedom and gender equality. In contrast to them are introduced the authors whose argumentation opposes stereotypical views of Islam; among them are also those that critically address Islamophobia in today’s Western society, either by presenting results of their research on Islamophobia or by documenting the dominant media image of Islam, which has been perpetuating stereotypes, especially in the aftermath of the terrorist attacks on New York in 2001. Lastly, it is concluded that, regardless of the origin of works dealing with the relationship between Islam and the West or of the type of their arguments, they more often than not interpret Islam and the West primarily as two separate, self-contained and in itself incompatible worlds. In doing so, the authors here argue, they employ an essentialist and reductionist approach not only to Islam – as it might be assumed – but also to the West, while the relationship between Islam and the West is simplified and schematized.

  5. Up-to-date knowledge of West Nile virus infection

    Directory of Open Access Journals (Sweden)

    Hrnjaković-Cvjetković Ivana


    Full Text Available Virus West Nile virus is a single-stranded RNA virus of the family Flaviviridae, genus Flavivirus. Epidemiology West Nile virus is maintained in the cycle involving culicine mosquitoes and birds .Humans typically acquire West Nile infection through a bite from infected adult mosquito. Person to person transmission can occur through organ transplantation, blood and blood product transfusions, transplacentally and via brest milk. Human cases of West Nile infections were recorded in Africa, Israel, Russia, India, Pakistan. In Romania in 1996 West Nile fever occurred with hundreds of neurologic cases and 17 fatalities. First human cases in the United States were in New York City where 59 persons were infected and had fever, meningitis, encephalitis and flaccid paralysis. Clinical manifestation Most human cases are asymptomatic. The majority of symptomatic patients have a self limited febrile illness. Fatigue, nausea, vomiting, eye pain, headache, myalgias, artralgias, lymphadenopathy and rash are common complaints. Less than 1% of all infected persons develop more severe neurologic illness including meningitis, encefalitis and flaccid paralysis. Laboratory diagnosis Diagnosis of West Nile virus infection is based on serologic testing, isolation of virus from patient samples and detection of viral antigen or viral genom. ELISA test and indirect immunofluorescenceassay are used for detecting IgM and IgG antibodies in serum and cerebrospinal fluid. Treatment In vitro studies have suggested that ribavirin and interferon alfa -2b may be useful in the treatment of West Nile virus disease. Prevention The most important measures are mosquito control program and personal protective measures. .

  6. The lion in West Africa is critically endangered. (United States)

    Henschel, Philipp; Coad, Lauren; Burton, Cole; Chataigner, Beatrice; Dunn, Andrew; MacDonald, David; Saidu, Yohanna; Hunter, Luke T B


    The African lion has declined to lions from other extant African populations. Interventions to save West African lions are urgently required. However formulating effective conservation strategies has been hampered by a lack of data on the species' current distribution, status, and potential management deficiencies of protected areas (PAs) harboring lions. Our study synthesized available expert opinion and field data to close this knowledge gap, and formulate recommendations for the conservation of West African lions. We undertook lion surveys in 13 large (>500 km²) PAs and compiled evidence of lion presence/absence for a further eight PAs. All PAs were situated within Lion Conservation Units, geographical units designated as priority lion areas by wildlife experts at a regional lion conservation workshop in 2005. Lions were confirmed in only 4 PAs, and our results suggest that only 406 (273-605) lions remain in West Africa, representing lion range is estimated at 49,000 km², or 1.1% of historical range in West Africa. PAs retaining lions were larger than PAs without lions and had significantly higher management budgets. We encourage revision of lion taxonomy, to recognize the genetic distinctiveness of West African lions and highlight their potentially unique conservation value. Further, we call for listing of the lion as critically endangered in West Africa, under criterion C2a(ii) for populations with lion range states in West Africa, we call for urgent mobilization of investment from the international community to assist range states to increase management effectiveness of PAs retaining lions.

    Hinzen, A. [DB Netz AG, Frankfurt am Main (Germany). Internationale Infrastrukturangelegenheiten


    The railway line between Aachen West and Montzen (and from there on to Antwerp) is one of the most important long-distance freight lines in Europe and today carries all the rail freight moved directly between Germany and Belgium. Despite that, a part of it has still not been electrified. The line was built during the First World War, when the territory was under German occupation. The two railway infrastructure managers concerned, Infrabel (Belgium) and DB Netz (Germany), are working on plans to plug this gap in the electrification of the European freight network ready for the timetable change in December 2008. This article, penned by a specialist, describes the vicissitudes of the line's history as well as the studies and project planning for its electrification. (orig.)

    Since the emergence of West Nile virus (WNV) in North America in 1999, there have been several reports of WNV activity in Central and South American countries. To detect WNV in Brazil, we performed a serological survey of horses from different regions of Brazil using recombinant peptides from domain III of WNV. Positive samples were validated with the neutralisation test. Our results showed that of 79 ELISA-positive horses, nine expressed WNV-specific neutralising antibodies. Eight of the infected horses were from the state of Mato Grosso do Sul and one was from the state of Paraíba. Our results provide additional evidence for the emergence of WNV in Brazil and for its circulation in multiple regions of the country. PMID:24037110

  10. Safety of West Nile Virus vaccines in sandhill crane chicks (United States)

    Olsen, G.H.; Miller, K.J.; Docherty, D.E.; Bochsler, V.S.; Folk, Martin J.; Nesbitt, Stephen A.


    West Nile virus arrived in North America in 1999 and has spread across the continent in the ensuing years. The virus has proven deadly to a variety of native avian species including sandhill cranes (Grus canadensis). In order to provide safe and efficacious protection for captive and released populations of whooping cranes (G. americana), we have conducted a series of four research projects. The last of these was a study of the effects of two different West Nile virus vaccines on young Florida sandhill crane (G. c. pratensis) chicks and subsequent challenge with the virus. We found that vaccinating crane chicks as early as day 7 post-hatch caused no adverse reactions or noticeable morbidity. We tested both a commercial equine vaccine West Nile - Innovator (Fort Dodge Laboratories, Fort Dodge, Iowa) and a new recombinant DNA vaccine (Centers for Disease Control). We had a 33% mortality in control chicks (n =6) from West Nile virus infection, versus 0% mortality in two groups of vaccinated chicks (n = 12), indicating the two vaccines tested were not only safe but effective in preventing West Nile virus.

  11. East-West Couples: Distribution, Characteristics and Stability

    Directory of Open Access Journals (Sweden)

    Daniel Lois


    Full Text Available Der Originalbeitrag in deutscher Sprache ist verfügbar unter: Bd. 40 (2015: Ausgewählte deutsche Beiträge.SOEP data were used to examine relationships consisting of one partner socialised in West Germany and one in East Germany and who presently reside in the “old” (former West German or “new” (newly formed East German federal states. The estimated share of east-west couples among all marriages or cohabiting couples rises continuously within the observed period reaching approximately two and eleven percent respectively by 2009. The specific characteristics of east-west couples are that their employment-related division of labour is relatively egalitarian, above-average the partners are of different confessions and practice different religions, at least one of the partners is frequently divorced and there is also a strong tendency towards unmarried cohabitation. Besides the place of socialisation, the present place of residence has an independent impact on the economic situation, division of labour and marriage propensity. Analyses of relationship stability reveal that east-west couples exhibit a relatively high risk of separation. This is partly due to religious differences between the partners, but primarily to the low marriage propensity and the overrepresentation of divorced persons within this type of relationship.

  12. Geographic signatures of North American West Coast estuaries (United States)

    Emmett, Robert; Llansó, Roberto; Newton, Jan; Thom, Ron; Hornberger, Michelle; Morgan, Cheryl; Levings, Colin; Copping, Andrea; Fishman, Paul


    West Coast estuaries are geologically young and composed of a variety of geomorphological types. These estuaries range from large fjords to shallow lagoons; from large to low freshwater flows. Natural hazards include E1 Niños, strong Pacific storms, and active tectonic activity. West Coast estuaries support a wide range of living resources: five salmon species, harvestable shellfish, waterfowl and marine birds, marine mammals, and a variety of algae and plants. Although populations of many of these living resources have declined (salmonids), others have increased (marine mammals). West Coast estuaries are also centers of commerce and increasingly large shipping traffic. The West Coast human population is rising faster than most other areas of the U.S. and Canada, and is distributed heavily in southern California, the San Francisco Bay area, around Puget Sound, and the Fraser River estuary. While water pollution is a problem in many of the urbanized estuaries, most estuaries do not suffer from poor water quality. Primary estuarine problems include habitat alterations, degradation, and loss; diverted freshwater flows; marine sediment contamination; and exotic species introductions. The growing West Coast economy and population are in part related to the quality of life, which is dependent on the use and enjoyment of abundant coastal natural resources.

Further, we call for listing of the lion as critically endangered in West Africa, under criterion C2a(ii for populations with <250 mature individuals. Finally, considering the relative poverty of lion range states in West Africa, we call for urgent mobilization of investment from the international community to assist range states to increase management effectiveness of PAs retaining lions.

  14. Soil investigation in cities of West Hungary (United States)

    Bidló, A.; Szżcs, P.; Horváth, A.; Kámán, O.; Németh, E.


    The antropogene effects have an influence on the environment since the flow of materials and energy is continuous and mutual. In order to investigate the soil properly we have collected samples from sample spots in three West Hungarian cities (Sopron, Szombathely and Székesfehévár). The soil samples were taken from 0-10 and 10-20 cms depth in each city within a standard network and also at industrial territories. The number of the sampling spots were between 104 and 144, depending on the size of the city and the problematic places in town. We have noted the GPS-coordinates of the point, the elevation over sea level, the date of collecting, the type of the urban area, the information about land usage, vegetation, grass covering, the type of cover and the origin of soil. We described the following characters of soil: the borderline between two layers, the amount of humus, the structure, the compactness, the root system, the skeletal percent, the color, the physical assortment, the separated element and the soil defect. We measured the soil samples in laboratory according to the following parameters: acidity (pHH2O, pHKCl), lime content, hidrolitical and exchange acidity, amount of exchangeable cation, the humus content, the total nitrogen content, the ammonium-lactat-acetous acid (AL) solvent potassium and phosphorus content, the KCl solvent magnesium and calcium content, the strength of ethylene-diamin-tetra-acetous (EDTA) and diethylene-triamin-penta-acetous (DTPA) measurements of manganese, copper, zinc and iron element, as well as the particle size distribution. The results of field and laboratory investigation are represented in a GIS system. We attempted to draw a conclusion in connection with the condition, contamination and history of contamination of soil. The results showed that there is close connection between the soil parameters and geological conditions. However, this connection shows a decrease in the centre of the city.

  15. Reconfiguring the West in Neil Jordan's short story "Love"

    Directory of Open Access Journals (Sweden)

    Stipe Grgas


    Full Text Available In introducing his article,  the author draws attention to the enormous importance space, especially the west of Ireland, has in the Irish culture and in the legitimization of Irish identity. The central part of the article is devoted to an analysis of Neil Jordan's  "A Love" in which the author describes the way Jordan uses the West as the privileged place of Irish self-representation. A close reading of the text shows the writer's strategies which subvert the conventional image of the West of Ireland  and the author voices the opinion that Jordan's text refers to the end of one conceptualization of Irish identity. Offering the concept of heterotopia (Foucault in his conclusion the author opens up the possibility of reading the representation of space in Jordan's story as his inscription of those places which were elided from the utopian Irish national saga.

  16. A Postmodernist Reading of Sam Shepard’s True West

    Directory of Open Access Journals (Sweden)

    Abdol Hossein Joodaki


    Full Text Available This paper attempts to render some vivid postmodernist features in Shepard’s True West (1980, which is inspired by myths of American life and popular culture. Shepard’s True West suggests so many interesting postmodern elements. With a departure from conventional norms of character, dialogue and narrative; the elements of pastiche, subjective irony, and savage humor have become hallmarks of most of his works. These features and some of the basic traces of postmodern literature, including Lyotard’s theory of the end of meta-narratives and language game, Derrida’s deconstruction and Baudrillard’s simulation, as well as language fragmentation, uncertainty and duality,  altogether, have given Shepard’s True West a postmodern atmosphere.

  18. Cold war, quantum foundations, and East-West collaboration

    Energy Technology Data Exchange (ETDEWEB)

    Skaar-Jacobsen, Anja [Niels Bohr Archive, Copenhagen (Germany)


    It is well-known that the cultural cold war changed the ideological line in the Soviet Union from the late 1940s and that this had serious implications for the autonomy of research in genetics and quantum foundations in the East bloc. However, besides the more narrow concern from the point of view of research in quantum foundations, I suggest that the ideological impact on quantum foundations also constituted an obstacle for attempts by Western physicists to bring about a rapprochement between physics in the east and west in general. In connection with re-establishing East-West co-operation between physicists after Stalin's death in 1953 this obstacle needed to be cleared away. In my talk I discuss these issues and how the Institute for Theoretical Physics in Copenhagen came to be an important meeting place for physicists from the East and West from the mid-1950s.

    The lion has historically probably been widespread at low densities in West and Central Africa, nowadays they are largely restricted to small isolated populations inside protected areas. The total number is probably between 1200 and 2700, the best possible guesstimate would be 1700. Mankind is the main cause for the suspected decline of lion populations, both inside and outside protected areas. Very little research has been done on West and Central African lions a few examples are summarized here. The international community is slowly becoming aware of threats to lions in the region and some initiatives for lion conservation have started.

  16. Future of West African Monsoon in A Warming Climate (United States)

    Raj, Jerry; Kunhu Bangalath, Hamza; Stenchikov, Georgiy


    West Africa is the home of more than 300 million people whose agriculture based economy highly relies on West African Monsoon (WAM), which produces a mean annual rainfall of 150 - 2,500 mm and variability and change of which have devastating impact on the local population. The observed widespread drought in West Africa during the 1970s and 1980s was the most significant drought at regional scale during the twentieth century. In this study, a high resolution AGCM, High Resolution Atmospheric Model (HiRAM), is used to study the effects of anthropogenic greenhouse warming on WAM. HiRAM is developed at GFDL based on AM2 and employs a cubed-sphere finite volume dynamical core and uses shallow convective scheme (for moist convection and stratiform cloudiness) instead of deep convective parameterization. Future projections are done using two representative concentration pathways, RCP 4.5 and RCP 8.5 from 2007 to 2050 at C360 (~25 km) resolution. Both RCP 4.5 and RCP 8.5 scenarios predict warming over West Africa during boreal summer, especially over Western Sahara. Also, both scenarios predict southward shift in WAM rainfall pattern and drying over Southern Sahara, while RCP 8.5 predicts enhanced rainfall over Gulf of Guinea. The intensification of rainfall over tropical latitudes is caused by increased low level winds due to warm SST over Gulf of Guinea.

  18. West German producers step up enhanced recovery techniques

    Energy Technology Data Exchange (ETDEWEB)


    With the lure of more than $12 for every barrel of oil they find, West German oil companies are leaving few rocks unturned in a scramble for additional crude reserves. Most are convinced that in onshore West Germany, at least, the biggest new finds may well be in reservoirs discovered some years back. Reservoir engineers and economists are convinced that the recent large increases in crude prices will make it economical to recover far more oil from wells than ever before. Using only the advanced recovery techniques now available, West German reserves, it is estimated, could more than double. Total original oil in place discovered in West Germany is put at more than 300 million tons, with at least 200 million tons of highly viscous crude located in the Ems area in the northwest corner of the country. Cumulative production to date totals just over 65 million tons; proven recoverable reserves total 81 million tons. This leaves some part to unfavorable economics. However, there are some 45 million breakthrough tons considered by experts to be potentially recoverable subject only to refinement of known recovery technology.

  10. Energy in the Mountain West: Colonialism and Independence

    Energy Technology Data Exchange (ETDEWEB)

    Steven Piet; Lloyd Brown; Robert Cherry; Craig Cooper; Harold Heydt; Richard Holman; Travis McLing


    In many ways, the mountain west (Alaska, Arizona, Colorado, Idaho, Montana, New Mexico, Nevada, Utah, Wyoming) is an energy colony for the rest of the United States: it is rich in energy resources that are extracted to fuel economic growth in the wealthier and more populous coastal regions. Federal agencies and global corporations often behave as if the mountain west is a place to be exploited or managed for the benefit of customers and consumers elsewhere. Yet, the area. is not vast empty space with a limitless supply of natural resources, but rather a fast-growing region with a diverse economic base dependent on a limited supply of water. New decision processes and collaborations are slowly changing this situation, but in a piecemeal fashion that places local communities at odds with powerful external interests. Proper planning of major development is needed to insure that the west has a strong economic and cultural future after the fossil energy resources decline, even if that might be a century from now. To encourage the necessary public discussions, this paper identifies key differences between the mountain west and the rest of the United States and suggests some holistic approaches that could improve our future. This paper is designed to provoke thought and discussion; it does not report new analyses on energy resources or usage. It is a summary of a large group effort.

  11. A century of glacier change in the American West (United States)

    Fountain, A. G.


    Over the past 100 years glaciers in the American West (exclusive of Alaska) have largely receded. The magnitude of the recession varies across the west, with the greatest loss in Montana and California (>50% area loss) and the least loss on the stratovolcanoes (>35%) of the Pacific Northwest. The variations can be broadly characterized by elevation. Our results suggest that increased mass loss caused by increased summer temperatures affect all glaciers, whereas increasing winter temperatures, that change the phase of precipitation from snow to rain adversely affect those glaciers less than 3000m in elevation. The high glaciers (>3000m) of California and Colorado appear to be immune to variations in snowfall making them sensitive to variations in temperature alone. We infer that these very small, steep glaciers can only hold a given amount of snow beyond which extra snow avalanches or is blown off. Conversely, during winters of little direct snowfall, additional snow may be added through win drift from the surrounding terrain. The relatively little glacier shrinkage on the stratovolcanoes is due to the high altitude of the glacier accumulation zones. An east to west decrease in glacier shrinkage from Montana through Washington is due to enhanced winter precipitation along the west coast that somewhat buffers ice loss due to summer temperatures and winter precipitation phase changes.

    Lassa fever is an acute viral zoonotic illness caused by Lassa virus, an arenavirus known to be responsible for a severe haemorrhagic fever characterised by fever, muscle aches, sore throat, nausea, vomiting and, chest and abdominal pain. The virus exhibits persistent, asymptomatic infection with profuse urinary virus excretion in the ubiquitous rodent vector, Mastomys natalensis. Lassa fever is endemic in West Africa and has been reported from Sierra Leone, Guinea, Liberia, and Nigeria. Some studies indicate that 300,000 to 500,000 cases of Lassa fever and 5000 deaths occur yearly across West Africa. Studies reported in English, that investigated Lassa fever with reference to West Africa were identified using the Medline Entrez-PubMed search and were used for this review. The scarcity of resources available for health care delivery system and the political instability that characterise the West African countries would continue to impede efforts for the control of Lassa fever in the sub-region. There is need for adequate training of health care workers regarding diagnostics, intensive care of patients under isolation, contact tracing, adequate precautionary measures in handling infectious laboratory specimens, control of the vector as well as care and disposal of infectious waste.

  4. Purpura fulminans associated with acute West Nile virus encephalitis. (United States)

    Shah, Sheevam; Fite, Laura Paul; Lane, Natalie; Parekh, Palak


    Purpura fulminans is a progressive thrombotic disorder that presents with widespread purpura due to deficiency or dysfunction of protein C or protein S. Lesions present as well-demarcated erythematous macules that progress to irregular areas of hemorrhagic necrosis.West Nile virus is a member of the Flaviviridae family transmitted to humans through the bite of various mosquito species. It manifests as West Nile fever in 25% of those infected and less commonly as neuroinvasive disease. An African American man in his fortiespresented with altered mental status and was noted to have evidence of disseminated intravascular coagulation according to his lab data. He then developed dusky skin discoloration and systemic flaccid bullae with desquamation. Biopsy was consistent with purpura fulminans and the patient eventually developed symmetric peripheral gangrene, requiring amputations of all four extremities. Infectious work up revealed positive testing for IgM and IgG antibodies in serum and cerebrospinal fluid leading to the diagnosis of acute West Nile Virus encephalitis. We present this case to describe the rarely reported association of purpura fulminans with West Nile Virus infection.

  16. Potential Climate Effects of Dust Aerosols' over West Africa (United States)

    JI, Z.; Wang, G.; Pal, J. S.; Yu, M.


    Climate in West Africa is under the influence of the West African monsoon circulation and mineral dust emitted from the Sahara desert (which is the world's largest source of mineral dust emission). Dust aerosols alter the atmospheric radiative fluxes and act as cloud condensation nuclei in the process of emission, transportation and deposition. However, our understanding regarding how dust aerosols influence the present-day and future climate of West Africa is very limited. In this study, a regional climate model RegCM4.3.4-CLM4.5 is used to investigate the potential climatic effects of dust aerosols both in present (1981-2000) and future (2081-2100) periods over WA. First, the model performance and dust climatic effects are evaluated. The contribution of dust climatic effects under RCP8.5 scenario and their confounding effects with land use change are assessed. Our results indicate that the model can reproduce with reasonable accuracy the spatial and temporal distribution of climatology, aerosol optical depth and surface concentration over WA. The shortwave radiative forcing of dust is negative in the surface and positive in the atmosphere, with greater changes in JJA and MAM compared to those in SON and DJF. Over most of West Africa, cooling is the dominant effect on temperature. Their impact on precipitation features a dipole pattern, with decrease in the north and increase in the south of West Africa. Despite the dust-induced decrease of precipitation amount, dusts cause extreme precipitation to increase. To evaluate the uncertainties surrounding our modeling results, sensitivity experiments driven by ICBC from MIROC-ESM and CESM and their dynamic downscaling results are used for comparisons. Results from these sensitivity experiments indicate that the impact of dust aerosols on present and future climate is robust.

  17. West Africa land use land cover time series (United States)

    Tappan, G. Gray; Cushing, W. Matthew; Cotillon, Suzanne E.; Mathis, Melissa L.; Hutchinson, John A.; Dalsted, K. J.


    The West Africa Land Use Dynamics Project provides AGRHYMET and its 17 participating countries a comprehensive two-kilometer (2-km) resolution land use land cover (LULC) dataset of the region for three time periods; 1975, 2000, and 2013. Hundreds of Landsat images were visually interpreted to develop a 2-km LULC dataset for each of the three time periods. To assist in validating the interpretations, thousands of aerial photographs and high-resolution satellite images were used. From the initial datasets produced by national teams, the U.S. Geological Survey (USGS) conducted an independent, detailed review of the interpretations. In concurrence with the respective country teams, the data have been revised to produce an accurate and consistent LULC assessment from within the countries and respective transboundary areas. This West Africa Land Use Dynamics Project represents an effort to document and quantify the impacts of change in both time and space, of the environmental and land resource trends across West Africa. The project was carried out through the AGRHYMET Regional Center in Niamey, Niger, in partners from 17 participating countries, the Sahel Institute (INSAH), the USGS Earth Resources Observation and Science (EROS), and with major support from the U.S. Agency for International Development (USAID) West Africa Regional Program. The overarching goal of the West Africa Land Use Dynamics Project is to promote the awareness of the trends and use of spatial information about natural resource trends among national and regional decision-makers.

  18. Diversity of Indo-West Pacific Siphonaria (Mollusca: Gastropoda: Euthyneura). (United States)

    Dayrat, Benoît; Goulding, Tricia C; White, Tracy R


    Species of the limpet genus Siphonaria (Gastropoda: Euthyneura) are commonly found in the rocky intertidal, worldwide, except in the Arctic. In total, 205 species-group names are available and not permanently invalid. However, estimating the actual species diversity of Siphonaria has remained challenging, mainly because past authors have interpreted differently the variation of shell characters, resulting in different taxonomic accounts. Species diversity of Siphonaria is evaluated for the first time here based on DNA sequence data (three mitochondrial gene fragments: COI, 12S, and 16S) and a large sampling focusing on the tropical and subtropical Indo-West Pacific (from eastern Africa to Hawaii): new sequences are provided for 153 individuals, 123 of which were collected from 93 locations throughout the Indo-West Pacific. In total, 41 species (molecular units) are recognized worldwide (31 from the Indo-West Pacific), all of which are strongly supported. Potential names are discussed for those 41 species, based on traditional taxonomy. The shells of 66 of the individuals from which DNA was extracted are illustrated: intra- and inter-specific variation is documented in detail and discussed in the light of new molecular results. It is shown that many species could hardly be identified based on the shell only, because the variation of shell characters is too high and overlaps between species. Geographically, no species is found across the entire Indo-West Pacific, where quite a few species seem to be endemic to restricted areas. The biogeography of Siphonaria in the Indo-West Pacific is compared to other groups.

  13. Investigative Journalism and Human Trafficking in West Africa

    Directory of Open Access Journals (Sweden)

    Veronika Gyuracz


    Full Text Available Investigative journalism that aims to prise out information that the state or certain businesses want to keep undisclosed has been unthinkable under many postcolonial African regimes. However, since the promulgation of democratic constitutions, a generation of ambitious investigative journalists has grown up in Africa. In order to show how journalism has changed, the paper brings Anas Aremeyaw Anas’s activities into focus. Anas’s single-minded mission to bring justice has targeted organisations involved in human trafficking, smuggling, and forced labour in West African countries since 2010. Although his team’s way of gathering information raises moral concerns about undercover journalism, their efforts illustrate that human trafficking is widespread among the countries of West and Central Africa. Therefore, the author suggests that both the AU and ECOWAS must create a more stable legal environment for investigative journalists, as their reports can help these institutions and national governments protect human rights.

  14. Case histories of West Valley spent fuel shipments: Final report

    Energy Technology Data Exchange (ETDEWEB)


    In 1983, NRC/FC initiated a study on institutional issues related to spent fuel shipments originating at the former spent fuel processing facility in West Valley, New York. FC staff viewed the shipment campaigns as a one-time opportunity to document the institutional issues that may arise with a substantial increase in spent fuel shipping activity. NRC subsequently contracted with the Aerospace Corporation for the West Valley Study. This report contains a detailed description of the events which took place prior to and during the spent fuel shipments. The report also contains a discussion of the shipment issues that arose, and presents general findings. Most of the institutional issues discussed in the report do not fall under NRC's transportation authority. The case histories provide a reference to agencies and other institutions that may be involved in future spent fuel shipping campaigns. 130 refs., 7 figs., 19 tabs.

    This paper described the work of welding process design for the "West-East" pipeline project, which is high pressure, large diameter and heavy wall thickness. According to the different geographical situation, climate, culture and the flexibility of the welding methods, this work recommended the semi-automatic process at the east and middle sections and automatic process at the west section of the pipeline project. The manual process is recommended on the tie-in joints and repairs. The double joint pipe and the 3 joint pipe are recommended at the water net place and some in-ditch welding place to reduce the welding volume. Also the special redesigned bevels are recommended for the automatic process and the semiautomatic process. Through all destructive tests, the results shows the welds are meet the requirements of related standards,specifications and design documents.

    Stratigraphic evidence is found for two coseismic subsidence events that underlie a floodplain 20 km south of Padang, West Sumatra along the Mentawai segment (0.5°S-0.3°S) of the Sunda subduction zone. Each earthquake is marked by a sharp soil-mud contact that represents a sudden change from mangrove to tidal flat. The earthquakes occurred about 4000 and 3000 cal years B.P. based on radiocarbon ages of detrital plant fragments and seeds. The absence of younger paleoseismic evidence suggests that late Holocene relative sea level fall left the floodplain too high for an earthquake to lower it into the intertidal zone. Our results point to a brief, few thousand year window of preservation of subsidence events in tidal-wetland stratigraphic sequences, a result that is generally applicable to other emergent coastlines of West Sumatra.

    Full Text Available Since the emergence of West Nile virus (WNV in North America in 1999, understanding of the clinical features, spectrum of illness and eventual functional outcomes of human illness has increased tremendously. Most human infections with WNV remain clinically silent. Among those persons developing symptomatic illness, most develop a self-limited febrile illness. More severe illness with WNV (West Nile neuroinvasive disease, WNND is manifested as meningitis, encephalitis or an acute anterior (polio myelitis. These manifestations are generally more prevalent in older persons or those with immunosuppression. In the future, a more thorough understanding of the long-term physical, cognitive and functional outcomes of persons recovering from WNV illness will be important in understanding the overall illness burden.

    Full Text Available In June 2009 we surveyed the terrestrial Tardigrada of Dominica, the most northerly of the Windward islands of the Lesser Antilles in the Caribbean sea. Out of 112 moss, lichen, liverwort and leaf litter samples, 35 had tardigrades, representing 10 genera and 25 species or species groups. This survey increases the number of species reported from Dominica from 3 to 25, more than the total recorded from any other West Indian island. Twelve species found in Dominica are cosmopolitan or belong to cosmopolitan species groups. Eight species are new to the fauna of the West Indies, one is new to the fauna of the Americas, and at least one is endemic to Dominica.

  1. Physicians' perceptions of doctor shopping in West Virginia. (United States)

    Shaffer, E Gail; Moss, Alvin H


    Prescription drug abuse and diversion continue to be serious problems in West Virginia and nationwide. Doctor shopping (visiting multiple doctors in a short time frame with the intent to deceive them to obtain controlled substances) is illegal and one way that patients gain access to prescription drugs. We surveyed West Virginia physicians in emergency medicine, family medicine, and internal medicine to determine their experience with and attitudes toward doctor shopping, and to assess attitudes toward proposed legislation to protect physicians who report doctor shoppers to law enforcement officials. Of 452 physicians surveyed, 258 responded (57%). Emergency medicine physicians had the highest response rate (61%) and most frequent encounters (once a week or more often) with doctor shoppers compared to family medicine and internal medicine physicians (88% vs 25% vs 14%, P doctor shoppers. If the law protected them, 85 percent of all physicians reported they would be likely to report doctor shoppers.

  2. Regional flood-frequency relations for west-central Florida (United States)

    Seijo, M.A.; Giovannelli, R.F.; Turner, J.F.


    This report presents regional relations for estimating the magnitude and frequency of floods on streams in west-central Florida. Flood prediction equations derived cover 20, 5-, 25-, 100-, 200-, and 500-year recurrence intervals. Annual floods for three geographic areas of west-central Florida were found to relate significantly to basin characteristics. Basin characteristics include drainage area, soils index, slope, and lake area. The average standard error of estimate for regional flood relations ranged from 38.4 to 52.1 percent with a mean of 43.5 percent. The average multiple correlation coefficient if 0.94. Regional relations apply to gaged and ungaged sites whose drainage areas are greater than 10 but less than 2,500 square miles. Tables of maximum known floods for 64 streamflow stations used in the analysis are included. Tables comparing station, weighted, and regional flood-peak discharges are also included. (Kosco-USGS)

    Odgaard, Bent Vad


    Holocene sediments of three closed Danish lake basins (Solso, Skånso, Kragso) were used for the inference of post-glacial vegetational dynamics in former heathland areas in northern West Jutland, Denmark. The sites were selected to represent the major geomorphological units of West Jutland....... The Holocene history of each lake basin was investigated by mapping of sediment distribution, analysis of loss-on-ignition, coarse inorganic matter, humus content, mineral magnetics, 6°C. pollen and selected other microfossils. These techniques were supplemented by plant macrofossil analysis at one site......, the synchronous timing of relatively rapid inferred change in lake and terrestrial vegetation around AD 600 may reflect changes in climate as well as in land-use. Redundancy analysis was used to develop a model between fire intensity (inferred from microscopical charred particles) and vegetational response...

  5. Testing Modeling Assumptions in the West Africa Ebola Outbreak (United States)

    Burghardt, Keith; Verzijl, Christopher; Huang, Junming; Ingram, Matthew; Song, Binyang; Hasne, Marie-Pierre


    The Ebola virus in West Africa has infected almost 30,000 and killed over 11,000 people. Recent models of Ebola Virus Disease (EVD) have often made assumptions about how the disease spreads, such as uniform transmissibility and homogeneous mixing within a population. In this paper, we test whether these assumptions are necessarily correct, and offer simple solutions that may improve disease model accuracy. First, we use data and models of West African migration to show that EVD does not homogeneously mix, but spreads in a predictable manner. Next, we estimate the initial growth rate of EVD within country administrative divisions and find that it significantly decreases with population density. Finally, we test whether EVD strains have uniform transmissibility through a novel statistical test, and find that certain strains appear more often than expected by chance. PMID:27721505

  6. Overview of West Nile Virus Transmission and Epidemiology. (United States)

    Troupin, Andrea; Colpitts, Tonya M


    West Nile virus (WNV) is a mosquito-borne flavivirus that can cause mild-to-severe disease in humans and horses. WNV was first documented in Uganda in 1937 and passed through the majority of Africa, West Asia, and Europe before arriving in the USA (with infections in New York City in 1999). After the spread of the virus on the US east coast, it traveled westward, northward, and southward through the USA and into Central and South America. WNV can cause fever, rashes, nausea, vomiting, and potentially neuroinvasive disease or death. The virus is sustained through a mosquito-bird-mosquito cycle and there are many species that are competent vectors. Unfortunately, there are no vaccines and the only treatment is supportive care. This chapter highlights the epidemiology and transmission of WNV and provides insight into some of the challenges of controlling WNV disease.

  9. Ukraine gas crisis rumbles on as west again affected

    Energy Technology Data Exchange (ETDEWEB)



    Russian disagreements with Ukraine have continued despite the earlier settlement of a dispute over gas pricing (see 'Focus', January 2006). Deliveries of Russian gas to the west have again been disrupted amid accusations from Moscow that Ukraine has been abstracting more gas from Russia's export pipeline than it is contractually entitled to. The problem, however, appears to originate in Russia, where cold weather has caused domestic demand for gas to soar, leaving less available for export. (author)

  13. Will elephants soon disappear from West African savannahs? (United States)

    Bouché, Philippe; Douglas-Hamilton, Iain; Wittemyer, George; Nianogo, Aimé J; Doucet, Jean-Louis; Lejeune, Philippe; Vermeulen, Cédric


    Precipitous declines in Africa's native fauna and flora are recognized, but few comprehensive records of these changes have been compiled. Here, we present population trends for African elephants in the 6,213,000 km² Sudano-Sahelian range of West and Central Africa assessed through the analysis of aerial and ground surveys conducted over the past 4 decades. These surveys are focused on the best protected areas in the region, and therefore represent the best case scenario for the northern savanna elephants. A minimum of 7,745 elephants currently inhabit the entire region, representing a minimum decline of 50% from estimates four decades ago for these protected areas. Most of the historic range is now devoid of elephants and, therefore, was not surveyed. Of the 23 surveyed elephant populations, half are estimated to number less than 200 individuals. Historically, most populations numbering less than 200 individuals in the region were extirpated within a few decades. Declines differed by region, with Central African populations experiencing much higher declines (-76%) than those in West Africa (-33%). As a result, elephants in West Africa now account for 86% of the total surveyed. Range wide, two refuge zones retain elephants, one in West and the other in Central Africa. These zones are separated by a large distance (∼900 km) of high density human land use, suggesting connectivity between the regions is permanently cut. Within each zone, however, sporadic contacts between populations remain. Retaining such connectivity should be a high priority for conservation of elephants in this region. Specific corridors designed to reduce the isolation of the surveyed populations are proposed. The strong commitment of governments, effective law enforcement to control the illegal ivory trade and the involvement of local communities and private partners are all critical to securing the future of elephants inhabiting Africa's northern savannas.

    The magnetic resonance imaging (MRI) findings of 19 low-birth-weight infants with periventricular leukomalacia (PVL) and cerebral palsy, 6 with West syndrome as a complication (group III) and 13 without it (group II), were compared with those of normal 13 low-birth-weight infants without PVL or cerebral palsy (group I) to investigate the pathogenetic mechanism of West syndrome. All of the subjects were born between 1989 and 1997, and there were no significant differences between the three groups in birth weight or age at the time of the examination. Although the gestation period was significantly longer in the group III (infants with West syndrome) than in group I (control infants), there was no significant difference was seen between group I and group II (infants with PVL and cerebral palsy). PVL was diagnosed by MRI, and the diagnostic standards included periventricular high signal intensity on T2-weighted images, decreased cerebral white matter, and deformity or enlargement of the lateral ventricles. The area of periventricular high signal intensity was significantly larger in group II and group III than in group I, and the occipital lobe white matter was significantly thinner in the former than the latter. The lateral ventricles were significantly larger in group II than in the other two groups. The area of the corpus callosum and the thickness of the splenium and trunk of the corpus callosum were significantly smaller in group II and group III than in group I, but the corpus callosum was significantly shorter in group III than in the other two groups. Findings in the brain stem showed a significantly smaller pons and medulla oblongata in group III than in group I, but there were no significant differences between group II and group I. The results of this study indicate that lower brainstem lesions as well as cerebral lesions are associated with the development of West syndrome. (K.H.)

  19. Product consistency testing of West Valley Compositional Variation Glasses

    Energy Technology Data Exchange (ETDEWEB)

    Olson, K.M.; Marschman, S.C.; Piepel, G.F.; Whiting, G.K.


    Nuclear waste glass produced by the West Valley Demonstration Project (WVDP) must meet the requirements of the Waste Acceptance Preliminary Specification (WAPS) as developed by the US Department of Energy (DOE). To assist WVDP in complying with WAPS, the Materials Characterization Center (MCC) at Pacific Northwest Laboratory (PNL) used the Product Consistency Test (PCT) to evaluate 44 West Valley glasses that had previously been tested in FY 1987 and FY 1988. This report summarizes the results of the PCTs. The glasses tested, which were fabricated as sets of Compositional Variation Glasses for studies performed by the West Valley Support Task (WVST) at PNL during FY 1987 and FY 1988, were doped with Th and U and were variations of West Valley reference glasses. In addition, Approved Reference Material-1 (ARM-1) was used as a test standard (ARM-1 is supplied by the MCC). The PCT was originated at Westinghouse Savannah River Company (WSRC) by C. M. Jantzen and N. R. Bibler (Jantzen and Bibler 1989). The test is a seven-day modified MCC-3 test that uses crushed glass in the size range -100 +200 mesh with deionized water in a Teflon container. There is no agitation during the PCT, and no attempt to include CO{sub 2} from the test environment. Based on B and Li release, the glasses performed about the same as in previous modified MCC-3 testing performed in FY 1987 and FY 1988 (Reimus et al. 1988). The modified MCC-3 tests performed by Reimus et al. were similar to the PCT containers and the exclusion of CO{sub 2} from the tests.

  2. Vertical plate motions in the West Siberian Basin (United States)

    Vibe, Yulia


    The West Siberian Basin is a sedimentary basin situated between the Ural Mountains and the Siberian Craton. The Basin has experienced several periods of subsidence and uplift since the arrival of the Siberian Traps c. 250 Ma. Although the Basin is extensively explored and hosts large reserves of Oil and Gas, the forces driving the vertical motions are poorly understood. In this work we attempt to analyse the amount, timing and location of subsidence and uplift in the Basin to shed light on the possible causes of these motions. A detailed description of sedimentary layers is published in a number of Soviet-era books and articles and serves as a basis for our research. This data is first converted into sediment grids through time. Subsequently, the sediments, the sediment load and the compaction are taken into account ('backstripping') to produce the depth of the Basin at respective time steps. With this technique we calculate the tectonic component of subsidence. Uncertainties related to uplift events are estimated by the unconformities in the stratigraphic charts. One of the possible driving forces of vertical motions is a change of force balance arising at plate boundaries. Since active plate tectonics have been absent from West Siberia since the formation of the Urengoy and Khodosey Rifts, c. 250Ma, we study the far-field tectonic effects as a potential driving mechanism. Indeed, some of the significant vertical events in the West Siberian Basin coincide with the major tectonic events around Siberia. An example is the spreading in the Arctic (Eurasian Basin) in the Eocene (56 Ma) which was synchronous with initiation of uplift events in the northern part of West Siberia. In the middle Oligocene (33 Ma), the northern and eastern parts of the basin were subjected to uplift as subsidence migrated southwards and the Basin rose above the sea level. This was coincident with the changes of plate motions in the northern North Atlantic and Indo-European collision.

  4. Intense convection over West Africa during AMMA SOP3 experiment (United States)

    Lenouo, André; Sall, Saïdou Moustapha; Badiane, Daouda; Gaye, Amadou Thierno; Kamga Mkankam, F.


    ERA-Interim product from the European Center for Medium-Range Weather Forecast (ECMWF) assimilation of African Monsoon Multidisciplinary Analysis (AMMA) resources, Meteosat satellite images, and synoptic observations were used to study local- and regional-scale environments associated with intense convective systems during the AMMA-SOP3 experiment over West Africa in the Northern Hemisphere of summer 2006. The convective system, from the 21st to 23rd of August 2006, was more active at 0000 and 1800 UTC showing diurnal cycle of deep convection over West Africa where the African easterly waves (AEWs) are developed downstream. Downstream barotropic and baroclinic energy conversions associated with strong AEWs are important for the maintenance of AEW activity in West Africa. Barotropic energy conversions dominate south of the African easterly jet (AEJ), while baroclinic energy conversions are most important north of the AEJ. From a dynamical viewpoint, the low-level vorticity presents strong positive values over the sea and Sahara zone, indicating that exists on the cyclonic shear side of the African easterly jet, which is consistent with baroclinic growth. The 925-hPa equivalent potential temperature structure show a maximum over the Sahara which corresponds to the depression observed in this region. A mosaic of three hourly infrared (IR) satellite images, depicts a very distinct signal from an initial region of convection, developing through several stages and moving off the African coast. These observations, along with those available from the World Weather Watch, provide an opportunity to carry out numerical weather prediction (NWP) studies over West Africa utilizing high resolution limited area models.

  9. Tributyltin accumulation and effects in marine molluscs from West Greenland

    Energy Technology Data Exchange (ETDEWEB)

    Strand, J.; Asmund, G


    Tributyltin is accumulated in marine molluscs living in Greenland, with the highest levels found in harbour areas. - The levels of the antifouling agent tributyltin (TBT) and its breakdown products in bivalves were investigated in 1999-2000 at six areas along the west coast of Greenland with focus on locations inside and outside harbours. In addition female gastropods were examined for the development of TBT-induced masculine characteristics in form of imposex or intersex. The highest TBT concentration, 254 ng g{sup -1} ww, was found in the bivalve Mytilus edulis sampled inside Nuuk harbour, but significant TBT concentrations were also present in bivalves from the other harbour areas. Only low levels of TBT were detected in bivalves sampled outside the harbours and in several of the samples the TBT level was below the detection limit. The examination of neogastropods like Buccinum revealed that imposex development occurred in all the harbours. In contrast, imposex was not found in any neogastropods sampled outside the harbour areas. However, the value of marine neogastropods as indicators of TBT contamination in West Greenland seems limited, because of large species diversity and the difficulties in sampling enough specimens at least with the current sampling strategy. No effects, which could be related to TBT contamination, were found in the most abundant tidal gastropod in West Greenland, Littorina saxatilis.

    W. Walczowski


    Full Text Available The structures of the hydrographic fronts separating the Atlantic origin waters from ambient waters in the northern Nordic Seas are discussed. Flows of the western and eastern branches of the West Spitsbergen Current create the Atlantic domain borders and maintain these fronts. The work is based on previous research and on investigations in the project DAMOCLES (Developing Arctic Modeling and Observational Capabilities for Long-term Environmental Studies. Most of the observational data were collected during the R/V Oceania cruises. The main focus of the paper is put on the western border of the Atlantic domain – the Arctic Front, along- and transfrontal transports, the front instability and variability. The baroclinic instability and advection of baroclinic eddies which occurs due to this instability were found as the main transfrontal transport processes. Most of the Atlantic Water transported by the western branch recirculates west and southward. The eastern branch of the West Spitsbergen Current provides most of the Atlantic Water entering the Arctic Ocean. Both processes are very important for the Arctic and global Thermohaline Circulation.

  13. West syndrome due to vitamin B12 deficiency. (United States)

    Serin, Hepsen Mine; Kara, Aslıhan Oruçoğlu; Oğuz, Baran


    Vitamin B12 is one of the essential vitamins affecting various systems of the body. Vitamin B12 deficiency in infants often produces haematological and neurological deficits including macrocyticanaemia, neurodevelopmental delay or regression, irritability, weakness, hypotonia, ataxia, apathy, tremor andseizures. In this article, we report the case of a six-month-old male patient diagnosed with West syndrome associated with vitamin B12 deficiency. Although the patient had no evidence of macrocytic anemia in complete blood count, we measured the level of vitamin B12 because the patient had hypotonicity and found it to be low. No other problem was found in the other investigations directed to the etiology of West syndrome. He was being exclusively breast-fed and vitamin B12 deficiency was related with nutritional inadequacy of his mother. Vitamin B12 deficiency should be considered in the differential diagnosis of patients presenting with different neurological findings. In addition, vitamin B12 deficiency should be considered as a rare cause in West syndrome which has a heterogeneous etiology.

    Hershko, C; Abrahamov, A; Moreb, J; Hersh, M; Shiffman, R; Shahin, A; Richter, E D; Konijn, A M; Weissenberg, E; Graver, F


    Eleven patients from the West Bank village of Es-Sawiyeh were admitted with lead poisoning to two Jerusalem hospitals between November 1982 and January 1983. They all belonged to several households of a single large family. Colicky abdominal pains were present in five patients, weakness in four, behavioral changes ranging from irritability to frank psychosis in four, and paralysis in one. Anemia of various degrees was seen in all patients. Basophilic stippling and reticulocytosis were encountered in all patients with moderate to severe anemia. Therapy with edetate disodium calcium and penicillamine resulted in clinical improvement in all patients. A preliminary survey of 270 subjects in the same village disclosed 84 subjects with abnormally elevated blood lead levels, 17 of whom had grade IV lead burden according to the Centers for Disease Control risk classification. Contamination of homemade flour by lead used for stabilizing the metal parts of stone mills was the source of poisoning. As the method of milling in many West Bank villages is similar, these findings may have important implications to the well being of a large section of the rural West Bank population.

  15. Incorporating vegetation feedbacks in regional climate modeling over West Africa (United States)

    Erfanian, A.; Wang, G.; Yu, M.; Ahmed, K. F.; Anyah, R. O.


    Despite major advancements in modeling of the climate system, incorporating vegetation dynamics into climate models is still at the initial stages making it an ongoing research topic. Only few of GCMs participating in CMIP5 simulations included the vegetation dynamics component. Consideration for vegetation dynamics is even less common in RCMs. In this study, RegCM4.3.4-CLM4-CN-DV, a regional climate model synchronously coupled with a land surface component that includes both Carbon-Nitrogen (CN) and Dynamic-Vegetation (DV) processes is used to simulate and project regional climate over West Africa. Due to its unique regional features, West Africa climate is known for being susceptible to land-atmosphere interactions, enhancing the importance of including vegetation dynamics in modeling climate over this region. In this study the model is integrated for two scenarios (present-day and future) using outputs from four GCMs participating in CMIP5 (MIROC, CESM, GFDL and CCSM4) as lateral boundary conditions, which form the basis of a multi-model ensemble. Results of model validation indicates that ensemble of all models outperforms each of individual models in simulating present-day temperature and precipitation. Therefore, the ensemble set is used to analyze the impact of including vegetation dynamics in the RCM on future projection of West Africa's climate. Results from the ensemble analysis will be presented, together with comparison among individual models.

    West Antarctica is one of the most rapidly warming regions on Earth, and this warming is closely connected with global sea level rise. The discovery of rapid climate change on the West Antarctic Ice Sheet (WAIS) has challenged previous explanations of Antarctic climate change that focused on strengthening of circumpolar westerlies in response to the positive polarity trend in the Southern Annular Mode. West Antarctic warming does not yet have a comprehensive explanation: dynamical mechanisms may vary from one season to the next, and these mechanisms very likely involve complex teleconnections with subtropical and tropical latitudes. The prime motivation for this proposal is that there has been no substantial atmospheric science or climatological field work on West Antarctica since the 1957 International Geophysical Year and that research continued for only a few years. Direct meteorological information on the WAIS has been limited to a few automatic weather stations for several decades, yet satellite imagery and meteorological reanalyses indicate that West Antarctica is highly susceptible to advection of warm and moist maritime air with related cloud cover, depending on the location and strength of low pressure cells in the Amundsen, Ross, and Bellingshausen Seas. There is a need to quantify the role of these changing air masses on the surface energy balance, including all surface energy components and cloud-radiative forcing. More generally, global climate model simulations are known to perform poorly over the Antarctic and Southern Oceans, and the marked scarcity of cloud information at southern high latitudes has so far inhibited significant progress. Fortunately, McMurdo Station, where the Atmospheric Radiation Measurement Facility’s (ARM’s) most advanced cloud and aerosol instrumentation is situated, has a meteorological relationship with the WAIS via circulation patterns in the Ross and Amundsen Seas. We can therefore gather sophisticated data with cloud

  18. The West Indies as a laboratory of biogeography and evolution. (United States)

    Ricklefs, Robert; Bermingham, Eldredge


    Islands have long provided material and inspiration for the study of evolution and ecology. The West Indies are complex historically and geographically, providing a rich backdrop for the analysis of colonization, diversification and extinction of species. They are sufficiently isolated to sustain endemic forms and close enough to sources of colonists to develop a dynamic interaction with surrounding continental regions. The Greater Antilles comprise old fragments of continental crust, some very large; the Lesser Antilles are a more recent volcanic island arc, and the low-lying Bahama Islands are scattered on a shallow oceanic platform. Dating of island lineages using molecular methods indicates over-water dispersal of most inhabitants of the West Indies, although direct connections with what is now southern Mexico in the Early Tertiary, and subsequent land bridges or stepping stone islands linking to Central and South America might also have facilitated colonization. Species-area relationships within the West Indies suggest a strong role for endemic radiations and extinction in shaping patterns of diversity. Diversification is promoted by opportunities for allopatric divergence between islands, or within the large islands of the Greater Antilles, with a classic example provided by the Anolis lizards. The timing of colonization events using molecular clocks permits analysis of colonization-extinction dynamics by means of species accumulation curves. These indicate low rates of colonization and extinction for reptiles and amphibians in the Greater Antilles, with estimated average persistence times of lineages in the West Indies exceeding 30Myr. Even though individual island populations of birds might persist an average of 2Myr on larger islands in the Lesser Antilles, recolonization from within the archipelago appears to maintain avian lineages within the island chain indefinitely. Birds of the Lesser Antilles also provide evidence of a mass extinction event within

  19. Ice stream retreat following the LGM and onset of the west Greenland current in Uummannaq Trough, west Greenland (United States)

    Sheldon, Christina; Jennings, Anne; Andrews, John T.; Ó Cofaigh, Colm; Hogan, Kelly; Dowdeswell, Julian A.; Seidenkrantz, Marit-Solveig


    The deglacial history and oceanography of Uummannaq Trough, central West Greenland continental shelf, was investigated using foraminiferal, sedimentological, and bathymetric records together with a radiocarbon chronology, providing a timeline for the retreat of glacial ice after the Last Glacial Maximum (LGM). To map ice stream retreat, data were collected from cores from the outer (JR175-VC45 and JR175-VC43) and inner (JR175-VC42) Uummannaq Trough. A large ice stream, fed by confluent glaciers draining the interior of the Greenland Ice Sheet, extended across the outer shelf during the LGM and was in retreat by 15.0 cal kyr BP. Foraminiferal data indicate that the 'warm' West Greenland Current (WGC) was established prior to 14.0 cal kyr BP, which is the hitherto earliest record of Atlantic Water found on the West Greenland shelf. For each of the cores, foraminifera indicate that ice sheet retreat was followed quickly by incursion of the WGC, suggesting that the warm water may have enhanced ice retreat. Prior to the Younger Dryas cold event, the radiocarbon chronology indicates that the ice sheet retreated to the mid-shelf, where it subsequently stabilised and formed a large grounding-zone wedge (GZW). After the Younger Dryas, around 11.5 cal kyr BP, the ice retreated rapidly from the GZW and into the fjords.

  20. Groundwater quality in West Virginia, 1993-2008 (United States)

    Chambers, Douglas B.; Kozar, Mark D.; White, Jeremy S.; Paybins, Katherine S.


    Approximately 42 percent of all West Virginians rely on groundwater for their domestic water supply. However, prior to 2008, the quality of the West Virginia’s groundwater resource was largely unknown. The need for a statewide assessment of groundwater quality prompted the U.S. Geological Survey (USGS), in cooperation with West Virginia Department of Environmental Protection (WVDEP), Division of Water and Waste Management, to develop an ambient groundwater-quality monitoring program. The USGS West Virginia Water Science Center sampled 300 wells, of which 80 percent were public-supply wells, over a 10-year period, 1999–2008. Sites for this statewide ambient groundwater-quality monitoring program were selected to provide wide areal coverage and to represent a variety of environmental settings. The resulting 300 samples were supplemented with data from a related monitoring network of 24 wells and springs. All samples were analyzed for field measurements (water temperature, pH, specific conductance, and dissolved oxygen), major ions, trace elements, nutrients, volatile organic compounds, fecal indicator bacteria, and radon-222. Sub-sets of samples were analyzed for pesticides or semi-volatile organic compounds; site selection was based on local land use. Samples were grouped for comparison by geologic age of the aquifer, Groups included Cambrian, Ordovician, Silurian, Devonian, Pennsylvanian, Permian, and Quaternary aquifers. A comparison of samples indicated that geologic age of the aquifer was the largest contributor to variability in groundwater quality. This study did not attempt to characterize drinking water provided through public water systems. All samples were of raw, untreated groundwater. Drinking-water criteria apply to water that is served to the public, not to raw water. However, drinking water criteria, including U.S. Environmental Protection Agency (USEPA) maximum contaminant level (MCL), non-enforceable secondary maximum contaminant level (SMCL

  1. Microbial Community Structure of Subglacial Lake Whillans, West Antarctica (United States)

    Achberger, Amanda M.; Christner, Brent C.; Michaud, Alexander B.; Priscu, John C.; Skidmore, Mark L.; Vick-Majors, Trista J.; Adkins, W.


    Subglacial Lake Whillans (SLW) is located beneath ∼800 m of ice on the Whillans Ice Stream in West Antarctica and was sampled in January of 2013, providing the first opportunity to directly examine water and sediments from an Antarctic subglacial lake. To minimize the introduction of surface contaminants to SLW during its exploration, an access borehole was created using a microbiologically clean hot water drill designed to reduce the number and viability of microorganisms in the drilling water. Analysis of 16S rRNA genes (rDNA) amplified from samples of the drilling and borehole water allowed an evaluation of the efficacy of this approach and enabled a confident assessment of the SLW ecosystem inhabitants. Based on an analysis of 16S rDNA and rRNA (i.e., reverse-transcribed rRNA molecules) data, the SLW community was found to be bacterially dominated and compositionally distinct from the assemblages identified in the drill system. The abundance of bacteria (e.g., Candidatus Nitrotoga, Sideroxydans, Thiobacillus, and Albidiferax) and archaea (Candidatus Nitrosoarchaeum) related to chemolithoautotrophs was consistent with the oxidation of reduced iron, sulfur, and nitrogen compounds having important roles as pathways for primary production in this permanently dark ecosystem. Further, the prevalence of Methylobacter in surficial lake sediments combined with the detection of methanogenic taxa in the deepest sediment horizons analyzed (34–36 cm) supported the hypothesis that methane cycling occurs beneath the West Antarctic Ice Sheet. Large ratios of rRNA to rDNA were observed for several operational taxonomic units abundant in the water column and sediments (e.g., Albidiferax, Methylobacter, Candidatus Nitrotoga, Sideroxydans, and Smithella), suggesting a potentially active role for these taxa in the SLW ecosystem. Our findings are consistent with chemosynthetic microorganisms serving as the ecological foundation in this dark subsurface environment, providing new

    Access to electricity is a major issue in West Africa. Governments have a difficult equation to solve. They naturally seek to offer their people a cheap kWh. But they are constrained by a production based largely on oil and therefore highly volatile production costs. How to fix an acceptable tariff, taking into account the investment needs required to expand the network and increase production? This analysis should provide some answers. The study presented in this paper provides a financial analysis of electricity utilities in West Africa. It allows a comparison of performances on a number of key financial ratios related to operations (Earning Before Interest Taxes Debt and Amortization/sales, working capital requirement/sales, days of receivables or payables), investment (net fixed assets/gross fixed assets), bank financing (financial structure, debt/EBITDA, interest expense/EBITDA) and economic and financial returns (Return On Capital Employed, Return On Equity). The conclusion focuses on the growth opportunity that the electricity sector could represent for each country. But this opportunity may only materialize if the EBITDA margins are restored. The available options appear limited and must be assessed taking into account the context of each country: tariff increase, improvement of technical losses or diversification into means of production no longer based primarily on oil or gas. - Highlights: > The study provides a financial analysis of electricity distribution companies in West Africa. > The study highlights generally insufficient EBITDA margins. > The study raises the question of tariffs and contribution to Gross Domestic Product of the electricity sector. > The conclusion focuses on the growth opportunity that the electricity sector could represent for each country.

    Claire van Deventer


    Full Text Available Background: Chronic illnesses are a significant burden to the health services in South Africa. There is a specific national health plan whereby chronically ill patients who are acceptably controlled should be managed at clinic level. The perception has emerged that the management of primary care has not been optimal in the Southern District of the North West Province. This provided the motivation to initiate this research, namely consideration of chronic patient care at clinics in the North West Province of South Africa.Method: A cross-sectional descriptive study was carried out at four randomly selected clinics covering four sub-districts in the Southern District (North West Province. This was done using charts and registers at the clinics. Inclusion criteria were patients older than 18, and presenting with the following chronic illnesses: asthma/chronic obstructive airways disease (COAD, hypertension, diabetes and epilepsy. The major focus areas were the regular assessment of the patients, the level of control of the illness and the use of the Essential Drugs List and Standard Treatment Guidelines (EDL/STG.Results: In the cases of all the chronic illnesses it was found that regular assessments were poorly done, with asthma (peak flow measurements being the most poorly done. Control was generally less than 50% for all the illnesses, although the EDL was followed fairly well by the personnel at the clinics.Conclusion: In the light of the burden of chronic illness the results give cause for great concern about the quality of care for chronically ill patients, and reasons were sought for some of the poor results. A subsequent decision was taken to carry out comprehensive quality improvement projects on each of the illnesses over the following five years.

  4. Cultural and landscape zoning in the North- West Russia

    Directory of Open Access Journals (Sweden)

    Manakov A. G.


    Full Text Available This research was conducted in the framework of cultural geography — a relatively recent field of geography. This article considers the problems of geographical study of cultural landscapes of the North-West Russia, which includes Saint Petersburg, the Leningrad, Novgorod, Pskov, and Kaliningrad regions. This article sets out to develop and test the methodology for historical and cultural zoning at the mesogeographical level. The research and practical significance of the work lies in the identification of the features of formation of cultural landscapes in the North-West Russia, which can be used for the development of schemes of protection and rational management of territorial cultural and historical heritage. The authors rely on historical and cultural zoning as the basic geographical method of research on cultural landscapes. To this effect, the article offers a hierarchy of historical and cultural zones comparable to the zoning systems applied in physical, historical, and cultural geography. The major results of the research are the authors' taxonomy of historical and cultural complexes and the corresponding system of historical and cultural zoning of the North-West Russia presented on a sketch map. The article offers an exemplary description of historical and cultural provinces of the region. The contribution of the research to the Russian geography of culture is the authors' variant of taxonomy of historical and cultural complexes and the formulation of basic principles of historical and cultural zoning at different hierarchical levels. The research results can be applied, first of all, in the development of projects aimed at the protection and use of territorial cultural heritage in the framework of comprehensive schemes of territorial planning of the country's regions.

  5. Climate drives the meningitis epidemics onset in west Africa.

    Benjamin Sultan


    Full Text Available BACKGROUND: Every year West African countries within the Sahelo-Sudanian band are afflicted with major meningococcal meningitis (MCM disease outbreaks, which affect up to 200,000 people, mainly young children, in one of the world's poorest regions. The timing of the epidemic year, which starts in February and ends in late May, and the spatial distribution of disease cases throughout the "Meningitis Belt" strongly indicate a close linkage between the life cycle of the causative agent of MCM and climate variability. However, mechanisms responsible for the observed patterns are still not clearly identified. METHODS AND FINDINGS: By comparing the information on cases and deaths of MCM from World Health Organization weekly reports with atmospheric datasets, we quantified the relationship between the seasonal occurrence of MCM in Mali, a West African country, and large-scale atmospheric circulation. Regional atmospheric indexes based on surface wind speed show a clear link between population dynamics of the disease and climate: the onset of epidemics and the winter maximum defined by the atmospheric index share the same mean week (sixth week of the year; standard deviation, 2 wk and are highly correlated. CONCLUSIONS: This study is the first that provides a clear, quantitative demonstration of the connections that exist between MCM epidemics and regional climate variability in Africa. Moreover, this statistically robust explanation of the MCM dynamics enables the development of an Early Warning Index for meningitis epidemic onset in West Africa. The development of such an index will undoubtedly help nationwide and international public health institutions and policy makers to better control MCM disease within the so-called westward-eastward pan-African Meningitis Belt.

  6. Monogeneans of West African cichlid fish: evolution and cophylogenetic interactions.

    Monika Mendlová

    Full Text Available The goals of this paper were to investigate phylogenetic and evolutionary patterns of cichlid fish from West Africa and their Cichlidogyrus and Scutogyrus monogenean parasites, to uncover the presence of host-parasite cospeciation and to assess the level of morphological adaptation in parasites. This required the following steps, each one representing specific objectives of this paper: (1 to build phylogenetic trees for Cichlidogyrus and Scutogyrus species based on ribosomal DNA sequences, (2 to investigate phylogenetic relationships within West African cichlid fish based on the analysis of mitochondrial cytochrome b DNA sequences, (3 to investigate host-parasite cophylogenetic history to gain clues on parasite speciation process, and (4 to investigate the link between the morphology of the attachment apparatus and parasite phylogeny. Phylogenetic analyses supported the monophyletic origin of the Cichlidogyrus/Scutogyrus group, and suggested that Cichlidogyrus is polyphyletic and that Scutogyrus is monophyletic. The phylogeny of Cichlidae supported the separation of mouthbrooders and substrate-brooders and is consistent with the hypothesis that the mouthbrooding behavior of Oreochromis and Sarotherodon evolved from substrate-brooding behavior. The mapping of morphological characters of the haptor onto the parasite phylogenetic tree suggests that the attachment organ has evolved from a very simple form to a more complex one. The cophylogenetic analyses indicated a significant fit between trees using distance-based tests, but no significant cospeciation signal using tree-based tests, suggesting the presence of parasite duplications and host switches on related host species. This shed some light on the diversification process of Cichlidogyrus species parasitizing West African cichlids.

    Patrick Mann; Christine Risch


    Final Report for '20% Wind by 2030: Overcoming the Challenges in West Virginia'. The objective of this project was to examine the obstacles and constraints to the development of wind energy in West Virginia as well as the obstacles and constraints to the achievement of the national goal of 20% wind by 2030. For the portion contracted with WVU, there were four tasks in this examination of obstacles and constraints. Task 1 involved the establishment of a Wind Resource Council. Task 2 involved conducting limited research activities. These activities involved an ongoing review of wind energy documents including documents regarding the potential for wind farms being located on reclaimed surface mining sites as well as other brownfield sites. The Principal Investigator also examined the results of the Marshall University SODAR assessment of the potential for placing wind farms on reclaimed surface mining sites. Task 3 involved the conducting of outreach activities. These activities involved working with the members of the Wind Resource Council, the staff of the Regional Wind Energy Institute, and the staff of Penn Future. This task also involved the examination of the importance of transmission for wind energy development. The Principal Investigator kept informed as to transmission developments in the Eastern United States. The Principal Investigator coordinated outreach activities with the activities at the Center for Business and Economic Research at Marshall University. Task 4 involved providing technical assistance. This task involved the provision of information to various parties interested in wind energy development. The Principal Investigator was available to answer requests from interested parties regarding in formation regarding both utility scale as well as small wind development in West Virginia. Most of the information requested regarded either the permitting process for wind facilities of various sizes in the state or information regarding the

    Recent aircraft and satellite laser altimeter surveys of the Amundsen Sea sector of West Antarctica show that local glaciers are discharging about 250 cubic kilometers of ice per year to the ocean, almost 60% more than is accumulated within their catchment basins. This discharge is sufficient to raise sea level by more than 0.2 millimeters per year. Glacier thinning rates near the coast during 2002-2003 are much larger than those observed during the 1990s. Most of these glaciers flow into flo...

  1. Chronic West Nile virus infection in kea (Nestor notabilis). (United States)

    Bakonyi, Tamás; Gajdon, Gyula K; Schwing, Raoul; Vogl, Wolfgang; Häbich, Annett-Carolin; Thaller, Denise; Weissenböck, Herbert; Rudolf, Ivo; Hubálek, Zdenek; Nowotny, Norbert


    Six kea (Nestor notabilis) in human care, naturally infected with West Nile virus (WNV) lineage 2 in Vienna, Austria, in 2008, developed mild to fatal neurological signs. WNV RNA persisted and the virus evolved in the birds' brains, as demonstrated by (phylo)genetic analyses of the complete viral genomes detected in kea euthanized between 2009 and 2014. WNV antibodies persisted in the birds, too. Chronic WNV infection in the brain might contribute to the circulation of the virus through oral transmission to predatory birds.

  10. Research on Impact Mechanism and Power System of Urbanization in West China

    Institute of Scientific and Technical Information of China (English)


    Based on the current situation of urbanization development in West China, this paper analyses main factors responsible for sluggish urbanization in West China as follows: impact of environment factor, impact of population quality and quantity, lagging of public product service, stagnancy of technological development, backwardness of slow growth, and rigidity of system building. And then this paper analyses the restriction mechanism of urbanization in West China: at the superficial level, the constraints of urbanization in West China arise from the shortage of capital; at the profound level, the backward culture contributes to the constraints of urbanization in West China. The thread of resolving restriction mechanism of urbanization in West China is put forward from system, economy and culture. On the basis of this thread, we construct the power system for the development of urbanization in West China. The power system for urbanization in West China should be propelled by "four forces", namely, pull of external forces, cohesive strength of regional market environment, expansion power inside countryside, traction of industrial structure adjustment. Innovation is the engine of impetus for urbanization in West China; spatial clustering and modernization of industry is the major driving force for urbanization; the government behaviour, driving of foreign investment, great projects and other forces are supplementary power. Via the main power, we should take the market as medium to achieve the role of power in promoting urbanization.

    Full Text Available Studies undertaken during the last 5 years in the Babol Research Station of the Institute of Public Health Research, Teheran University, with the collaboration of the International Agency for Research on Cancer in the Caspian Littoral and Ardabil area in the north of Iran has indicated the presence of cancer in 48 different sites. The five more prevalent types of cancer found in that area in order of their incidence are esophageal, stomach, skin, lung and liver cancers. Except for cancer of esophagus which occurs with a very high variation in incidence in the area, the incidence of other 4 does not significantly differ in various parts of the region. The incidence of esophageal cancer is maximum in the east and southeast of the area and it gradually decreases towards the reaching its minimum level in Gilan and increasing again to the west in Ardabil area. The incidence is higher among males in the low incidence, almost equal in the high incidence area except in Gombad area where is much higher among females than in males. The total number of cancer of soesophagus registered during the 5 years period is 1420 which constitute 1/10 of all cases reported. Of other types of cancer registered, cancers of skin, cervix uteri and lymphoma, mostly lymphosarcoma are more prevalent. Of the cancers of digestive tube, oesophageal is more prevalent in the east and stomach cancer in the west of the area.

  12. Desertification, refugees and regional conflict in west Africa. (United States)

    Nnoli, O


    This article documents the potential for inter-state conflict in the migration of hundreds of thousands of famine refugees across international borders in West Africa. Nigeria and Ghana, for example, have to deal not only with the effects of land degradation in their northern territories but also with the influx of famine victims from Mali, Niger, Chad and Burkino Faso. These migrations put an enormous extra burden on the fragile and already overstretched social and economic infrastructures of the host countries. The construction of dams for irrigation and electricity generation in international river basins, is another cause of inter-state conflict related to land degradation. The capacity of West African states to find peaceful solutions to these problems is being undermined by the increasing impoverishment and marginalisation of their populations. A self-serving neo-colonialist governing elite is caught in the economic stranglehold of the advanced capitalist nations. While there is thus no short term solution to the problem of land degradation, immediate steps should at least be taken to give legal protection to those who are forced to cross international borders because of drought and famine.

    Full Text Available The purpose of this study was to determine the feasibility of the coffee industry folk as a commercial producer in West Kalimantan. Research conducted descriptive and observation to determine the potential of raw materials, market potential and marketing, availability of technology, and financial feasibility analyzes plant establishment. The results of the study showed that the availability of raw materials such as coffee yields declined every year and its availability on every small community, and not attractive to farmers for commercial cultivation, where plants cannot compete with rubber, palm oil, or other horticultural crops or plantation, so people are reluctant to plant coffee again. Although, the marketing of coffee available on the domestic market, national market and abroad, but the quality of the coffee that is associated with superior taste, aroma, and geography indications is its own advantages, which have not seemed to result from West Kalimantan coffee. Coffee processing technology indicates the readiness of technology for applications, such as the technology to produce coffee of primary and secondary copy. Advice can be given is the cultivation of coffee and wild civet coffee products (Paradoxurus hermaphrodites from Sambas district and fostered intensive note by the local government, in order to have a competitive commercialization opportunities. Local Government should re-establish cultivation techniques and management of coffee farming.


    Energy Technology Data Exchange (ETDEWEB)



    In 2010, an innovative, remotely operated retrieval system was deployed to successfully retrieve over 99.7% of the radioactive sludge from ten submerged tanks in Hanford's K-West Basin. As part of K-West Basin cleanup, the accumulated sludge needed to be removed from the 0.5 meter diameter by 5 meter long settler tanks and transferred approximately 45 meters to an underwater container for sampling and waste treatment. The abrasive, dense, non-homogeneous sludge was the product of the washing process of corroded nuclear fuel. It consists of small (less than 600 micron) particles of uranium metal, uranium oxide, and various other constituents, potentially agglomerated or cohesive after 10 years of storage. The Settler Tank Retrieval System (STRS) was developed to access, mobilize and pump out the sludge from each tank using a standardized process of retrieval head insertion, periodic high pressure water spray, retraction, and continuous pumping of the sludge. Blind operations were guided by monitoring flow rate, radiation levels in the sludge stream, and solids concentration. The technology developed and employed in the STRS can potentially be adapted to similar problematic waste tanks or pipes that must be remotely accessed to achieve mobilization and retrieval of the sludge within.

  16. Tsunami Preparedness Along the U.S. West Coast (video) (United States)

    Filmed and edited by: Loeffler, Kurt; Gesell, Justine


    Tsunamis are a constant threat to the coasts of our world. Although tsunamis are infrequent along the West coast of the United States, it is possible and necessary to prepare for potential tsunami hazards to minimize loss of life and property. Community awareness programs are important, as they strive to create an informed society by providing education and training. This video about tsunami preparedness along the West coast distinguishes between a local tsunami and a distant event and focuses on the specific needs of each region. It offers guidelines for correct tsunami response and community preparedness from local emergency managers, first-responders, and leading experts on tsunami hazards and warnings, who have been working on ways of making the tsunami affected regions safer for the people and communities on a long-term basis. This video was produced by the US Geological Survey (USGS) in cooperation with the California Emergency Management Agency (CalEMA), Oregon Department of Geology and Mineral Industries (DOGAMI), Washington Emergency Management Division (EMD), Marin Office of Emergency Services, and Pacific Gas and Electric (PG&E).

    Makenas, B.J., Westinghouse Hanford


    Data Quality Objectives have been developed for a limited campaign of sampling K Basin canister sludge. Specifically, samples will be taken from the sealed K West Basin fuel canisters. Characterization of the sludge in these canisters will address the needs of fuel retrieval which are to collect and transport sludge which is currently in the canisters. Data will be gathered on physical properties (such as viscosity, particle size, density, etc.) as well as on chemical and radionuclide constituents and radiation levels of sludge. The primary emphasis will be on determining radionuclide concentrations to be deposited on Ion Exchange Modules (IXMS) during canister opening and fuel retrieval. The data will also be useful in determining whether K West Basin sludge meets the waste acceptance criteria for Hanford waste tanks as a backup disposal concept and these data will also supply information on the properties of sludge material which will1403 accompany fuel elements in the Multi-Canister Overpacks (MCOS) as envisioned in the Integrated Process Strategy (IPS).

    Recent developments, with new exploration both on-and offshore West Greenland in the 1990s, have been strongly driven by encouraging research results. Some of the most important break-through were made in the offshore area where new seismic data revealed large structures, either tilted fault blocks or compressional features, on seismic lines and direct hydrocarbon indicators in the form of flat spots. The discovery of extensive seepage of different oil types in the Disko - Nuussuaq - Svartenhuk Halvoe area, providing evidence of multiple oil-prone source rocks in this area has also been very important in attracting industry to the region. Based on previous successes several new research project were initiated in 1998, and more will follow in 1999 and the years to come. The project cover most aspects of petroleum geology and geophysics both on and offshore West Greenland. Some of these are highlighted at the end of the present article, which also provides a brief account of the field work carried out in 1998; reviews of recent summaries of results from groenArctic's GRO-3 well from which data have been released, and of recent GEUS and industry activities offshore, are also given.

  19. An interventional model to develop health professionals in West Africa. (United States)

    Sanou, Anselme Simeon; Awoyale, Florence Adeola; Diallo, Abdoulaye


    The health sector is characterized by a human resource base lacking in numbers, specialized skills, and management skills. West African Health Organization (WAHO) recognizes the need within the West Africa sub-region for bilingual professionals who are skilled in public health, management, leadership, and information technology to build human capacity in public health and developed the Young Professionals Internship Program (YPIP). Our study explores the evolution of the programme. YPIP program has successfully carried out its original aims and objectives to equip young professionals with basic principles of public health, management, and leadership, acquire competence in a second official language (French, English, and Portuguese), information and communication technology. Contributing factors towards this successful evaluation included positive ratings and commentary from previous interns about the relevance, usefulness, and quality of the programme, encouraging feedback from WAHO management, trainers, administrators, and intern employers on the impact of the YPIP program on young professionals, supporting evidence that demonstrates increased knowledge in professional skills and language competency.

  20. Prospects and constraints of desert agriculture: lessons from West Omdurman. (United States)

    El Gamri, Tarig


    Sudan is the largest country in Africa with an area of about 2.5 million km2; the country hosts a population of about 31 million people. About two-thirds of the country area is located within arid and semi-arid regions. Recently, especially during the last half of the previous century, these regions were subject to various forms of land degradation. This paper discusses the general prospects and constraints of desert agriculture. It also presents a detailed case study of West Omdurman, which is located in a semi-desert climatic zone. The ambitious plans to utilise the area for agricultural production were initiated because of the relatively fertile soil, availability of water and the proximity of the area to marketing and export centres. The paper discusses the different land use systems experienced in the area, reasons for failure are identified and possible remedies discussed. In addition, constraints facing the proposed West Omdurman Canal Project are also discussed. Finally, the paper reviews the major research findings of Rawakeeb Dryland Research Center with regard to promoting agricultural productivity.

  1. The Younger Dryas in the West Pacific marginal seas

    Institute of Scientific and Technical Information of China (English)

    汪品先; 卞云华; 李保华; 黄奇瑜


    The occurrence and nature of the Younger Dryas (YD) abrupt climatic event in the West Pacific marginal seas are discussed on the basis of 15 sediment cores. This event has been found in all these cores studied with a high-resolution stratigraphy and proved to be common to the West Pacific region. As shown by the isotopic and micropaleontologic analyses, the YD, dated by C-14 at about 11000 to 10000 a B.P., is a brief event of sea surface cooling in winter season following a fresh-water pulse about 12000 a B.P. The "apparent regression" of the YD recorded in the Changjiang River delta and the Sea of Japan agrees with the interpretation that the YD is a period of slowed sea level rising between two phases of rapid rising. Both the winter surface water cooling and the increasing salinity in the YD imply a strengthening of the winter, but not summer monsoon circulation. This major climatic event in the marginal seas must have had profound impact on the adjacent continent.

  2. Noma: experiences with a microvascular approach under West African conditions. (United States)

    Giessler, Goetz A; Schmidt, Andreas B


    Noma (cancrum oris) is a serious ulcerating disease that generally begins in the gingival sulcus of children. One of the main areas of prevalence today is West Africa. If noma is survived, it results in disfiguring midfacial defects and intense scarring. Oral incompetence is often combined with trismus resulting from scar formation or bony fusion between the maxilla and the mandible. Reconstructive approaches with pedicled flaps from the head or shoulder area for closure of the outer defects have been prone to donor-site complications or have not properly addressed the trismus, leading to high recurrence rates. During three West African Interplast missions, a single-stage procedure was developed for reconstruction of the inner and outer linings of the oral, nasal, and paranasal cavities, with restoration of jaw function. The procedure consists of radical scar excision, placement of an external distractor for mouth opening, and primary closure of the defect with a folded free parascapular flap for full-thickness coverage. Twenty-three patients with various noma-related defects were treated with this procedure; two cases are described in detail. This combined treatment can be a safe successful procedure for patients with noma, especially those with severe soft-tissue destruction and profound trismus, even under demanding surgical conditions.

  3. Black hole in the West Nucleus of Arp 220

    CERN Document Server

    Downes, D


    We present new observations with the IRAM Interferometer, in its longest-baseline configuration, of the CO(2-1) line and the 1.3mm dust radiation from the Arp 220 nuclear region. The dust source in the West nucleus has a size of 0.19 x 0.13 arcsec and a 1.3mm brightness temperature of 90K. This implies that the dust ring in the West nucleus has a high opacity, with tau = 1 at 1.1mm. Not only is the dust ring itself optically thick in the submm and far-IR, but it is surrounded by the previously-known, rapidly rotating molecular disk of size 0.5 arcsec that is also optically thick in the mid-IR. The molecular ring is cooler than the hot dust disk because the CO(2-1) line is seen in absorption against the dust disk. The dust ring is massive (1E9 solar masses), compact (radius 35pc), and hot (true dust temperature 170K). It resembles rather strikingly the dust ring detected around the quasar APM 08279+52, and is most unlike the warm, extended dust sources in starburst galaxies. Because there is a strong temperatu...

  4. Unconformity structures controlling stratigraphic reservoirs in the north-west margin of Junggar basin, North-west China (United States)

    Wu, Kongyou; Paton, Douglas; Zha, Ming


    Tectonic movements formed several unconformities in the north-west margin of the Junggar basin. Based on data of outcrop, core, and samples, the unconformity is a structural body whose formation associates with weathering, leaching, and onlap. At the same time, the structural body may be divided into three layers, including upper layer, mid layer, and lower layer. The upper layer with good primary porosity serves as the hydrocarbon migration system, and also accumulates the hydrocarbon. The mid layer with compactness and ductility can play a role as cap rock, the strength of which increases with depth. The lower layer with good secondary porosity due to weathering and leaching can form the stratigraphic truncation traps. A typical stratigraphic reservoir lying in the unconformity between the Jurassic and Triassic in the north-west margin of the Junggar basin was meticulously analyzed in order to reveal the key controlling factors. The results showed that the hydrocarbon distribution in the stratigraphic onlap reservoirs was controlled by the onlap line, the hydrocarbon distribution in the stratigraphic truncation reservoirs was confined by the truncation line, and the mid layer acted as the key sealing rock. So a conclusion was drawn that "two lines (onlap line and truncation line) and a body (unconformity structural body)" control the formation and distribution of stratigraphic reservoirs.

  6. Reserve Growth in Oil Fields of West Siberian Basin, Russia (United States)

    Verma, Mahendra K.; Ulmishek, Gregory F.


    Although reserve (or field) growth has proven to be an important factor contributing to new reserves in mature petroleum basins, it is still a poorly understood phenomenon. Limited studies show that the magnitude of reserve growth is controlled by several major factors, including (1) the reserve booking and reporting requirements in each country, (2) improvements in reservoir characterization and simulation, (3) application of enhanced oil recovery techniques, and (4) the discovery of new and extensions of known pools in discovered fields. Various combinations of these factors can affect the estimates of proven reserves in particular fields and may dictate repeated estimations of reserves during a field's life. This study explores the reserve growth in the 42 largest oil fields in the West Siberian Basin, which contain about 55 percent of the basin's total oil reserves. The West Siberian Basin occupies a vast swampy plain between the Ural Mountains and the Yenisey River, and extends offshore into the Kara Sea; it is the richest petroleum province in Russia. About 600 oil and gas fields with original reserves of 144 billion barrels of oil (BBO) and more than 1,200 trillion cubic feet of gas (TCFG) have been discovered. The principal oil reserves and most of the oil fields are in the southern half of the basin, whereas the northern half contains mainly gas reserves. Sedimentary strata in the basin consist of Upper Triassic through Tertiary clastic rocks. Most oil is produced from Neocomian (Lower Cretaceous) marine to deltaic sandstone reservoirs, although substantial oil reserves are also in the marine Upper Jurassic and continental to paralic Lower to Middle Jurassic sequences. The majority of oil fields are in structural traps, which are gentle, platform-type anticlines with closures ranging from several tens of meters to as much as 150 meters (490 feet). Fields producing from stratigraphic traps are generally smaller except for the giant Talin field which

    Smith Valerie


    Full Text Available Abstract Background Two thirds of all falciparum malaria cases reported in the United Kingdom (UK are acquired in West Africa (WA. To ensure recommendations and guidelines for malaria prophylaxis in travellers to West Africa correlate to the risk of infection, a study was undertaken to examine recent trends and predict future patterns of imported malaria acquired by UK residents visiting West Africa and West African visitors to the UK between 1993 and 2006. Methods and Results Using passenger numbers and malaria surveillance reports, the data revealed a 2.3-fold increase in travel to West Africa with a five-fold increase in travelers visiting friends and relatives (VFR. Malaria incidence fell through the study period, the greatest decline noted in VFR with a fall from 196 cases/1,000 person-years to 52 cases/1,000 person-years, 9.8% per year p Discussion The reduction in incidence among all three groups of travellers may be explained by several factors; changing chemoprophylaxis usage and/or increased travel in urban areas where malaria risk has declined over the past decade, or widespread reduction in malaria transmission in West Africa. Conclusion With the reduction in malaria incidence seen in both visitors to and from West Africa, the most rational explanation for these findings is a fall in malaria transmission in West Africa, which may require a change in chemoprophylaxis policy for UK travelers over the next 5–10 years.

    Full Text Available Based on the research results, the scientific work indicates economic trends and issues in the territorial organization of the economy and population of West Kazakhstan region. Analysis of the spatial development in the economic sphere has shown that there is a territorial localization of the productive forces in the north of West Kazakhstan region. The typology of the West Kazakhstan administrative districts was formed according to their level and pace of socioeconomic and environmental development, from 1997 to 2011, on the basis of rank-scoring methodology. The results of this work demonstrate that the Northern administrative districts of West Kazakhstan region have a relatively high or an average level of social and economic development.  A low level of social and economic development characterizes the administrative districts located to the south, west, southwest and southeast of West Kazakhstan region. These spatial differences reveal the current asymmetry in the level of social and economic development of the administrative districts, which determined the need for detecting major priorities in regulation of spatial social and economic development of the region.  Thus, we propose the basic priorities for the spatial regulation of social and economic development of West Kazakhstan region within the framework of an effective intra-regional policy.  The research results can be used by local government agencies to develop a regional management program for spatial social and economic development of West Kazakhstan region.

  3. Willingness to Pay for Mosquito Control in Key West, Florida and Tucson, Arizona. (United States)

    Dickinson, Katherine L; Hayden, Mary H; Haenchen, Steven; Monaghan, Andrew J; Walker, Kathleen R; Ernst, Kacey C


    Mosquito-borne illnesses like West Nile virus (WNV) and dengue are growing threats to the United States. Proactive mosquito control is one strategy to reduce the risk of disease transmission. In 2012, we measured the public's willingness to pay (WTP) for increased mosquito control in two cities: Key West, FL, where there have been recent dengue outbreaks, and Tucson, AZ, where dengue vectors are established and WNV has been circulating for over a decade. Nearly three quarters of respondents in both cities (74% in Tucson and 73% in Key West) would be willing to pay $25 or more annually toward an increase in publicly funded mosquito control efforts. WTP was positively associated with income (both cities), education (Key West), and perceived mosquito abundance (Tucson). Concerns about environmental impacts of mosquito control were associated with lower WTP in Key West. Expanded mosquito control efforts should incorporate public opinion as they respond to evolving disease risks.

  6. Demand Response in the West: Lessons for States and Provinces

    OAK-B135 This paper is submitted in fulfillment of DOE Grant No. DE-FG03-015F22369 on the experience of western states/provinces with demand response (DR) in the electricity sector. Demand-side resources are often overlooked as a viable option for meeting load growth and addressing the challenges posed by the region's aging transmission system. Western states should work together with utilities and grid operators to facilitate the further deployment of DR programs which can provide benefits in the form of decreased grid congestion, improved system reliability, market efficiency, price stabilization, hedging against volatile fuel prices and reduced environmental impacts of energy production. This report describes the various types of DR programs; provides a survey of DR programs currently in place in the West; considers the benefits, drawbacks and barriers to DR; and presents lessons learned and recommendations for states/provinces.

  7. East-west faults due to planetary contraction

    CERN Document Server

    Beuthe, Mikael


    Contraction, expansion and despinning have been common in the past evolution of Solar System bodies. These processes deform the lithosphere until it breaks along faults. The type and orientation of faults are usually determined under the assumption of a constant lithospheric thickness, but lithospheric thinning can occur at the equator or at the poles due either to latitudinal variation in solar insolation or to localized tidal dissipation. Using thin elastic shells with variable thickness, I show that the equatorial thinning of the lithosphere transforms the homogeneous and isotropic fault pattern caused by contraction/expansion into a pattern of faults striking east-west, preferably formed in the equatorial region. By contrast, lithospheric thickness variations only weakly affect the despinning faulting pattern consisting of equatorial strike-slip faults and polar normal faults. If contraction is added to despinning, the despinning pattern first shifts to thrust faults striking north-south and then to thrus...

  8. A Mouse Model of Chronic West Nile Virus Disease (United States)

    Graham, Jessica B.; Swarts, Jessica L.; Wilkins, Courtney; Thomas, Sunil; Green, Richard; Sekine, Aimee; Voss, Kathleen M.; Mooney, Michael; Choonoo, Gabrielle; Miller, Darla R.; Pardo Manuel de Villena, Fernando; Gale, Michael


    Infection with West Nile virus (WNV) leads to a range of disease outcomes, including chronic infection, though lack of a robust mouse model of chronic WNV infection has precluded identification of the immune events contributing to persistent infection. Using the Collaborative Cross, a population of recombinant inbred mouse strains with high levels of standing genetic variation, we have identified a mouse model of persistent WNV disease, with persistence of viral loads within the brain. Compared to lines exhibiting no disease or marked disease, the F1 cross CC(032x013)F1 displays a strong immunoregulatory signature upon infection that correlates with restraint of the WNV-directed cytolytic response. We hypothesize that this regulatory T cell response sufficiently restrains the immune response such that a chronic infection can be maintained in the CNS. Use of this new mouse model of chronic neuroinvasive virus will be critical in developing improved strategies to prevent prolonged disease in humans. PMID:27806117

    Vassilellis, George D.; Li, Charles; Bust, Vivian K. [Gaffney, Cline and Associates (United States); Moos, Daniel; Cade, Randal [Baker Hughes Inc (United States)


    With the depletion of conventional fossil fuels and the rising energy demand, oil shale and shale gas are becoming an important component of the oil and gas markets in North America. The aim of this paper is to present a novel methodology for predicting production in shale and tight formations. This method, known as the shale engineering approach and modeling, provides reservoir simulations based on modeling the propagation of the simulated rock volume. This technique was applied to an Upper Devonian shale formation in West Virginia, United States, and was compared to available data such as production logs and downhole microseismic data. Results showed a good match between the shale engineering approach data and early well performance. This paper presented a new reservoir simulation methodology which is successful in forecasting production and which can also be used for field development design and optimization.

  10. West syndrome in a patient with Schinzel-Giedion syndrome. (United States)

    Miyake, Fuyu; Kuroda, Yukiko; Naruto, Takuya; Ohashi, Ikuko; Takano, Kyoko; Kurosawa, Kenji


    Schinzel-Giedion syndrome is a rare recognizable malformation syndrome defined by characteristic facial features, profound developmental delay, severe growth failure, and multiple congenital anomalies. The causative gene of Schinzel-Giedion syndrome, SETBP1, has been identified, but limited cases have been confirmed by molecular analysis. We present a 9-month-old girl affected by West syndrome with Schinzel-Giedion syndrome. Congenital severe hydronephrosis, typical facial features, and multiple anomalies suggested a clinical diagnosis of Schinzel-Giedion syndrome. Hypsarrhythmia occurred at 7 months of age and was temporarily controlled by adrenocorticotropic hormone (ACTH) therapy during 5 weeks. SETBP1 mutational analysis showed the presence of a recurrent mutation, p.Ile871Thr. The implications in management of Schinzel-Giedion syndrome are discussed.

  11. The innate immune playbook for restricting West Nile virus infection. (United States)

    Quicke, Kendra M; Suthar, Mehul S


    West Nile virus (WNV) is an emerging mosquito-borne flavivirus that causes annual epidemics of encephalitic disease throughout the world. Despite the ongoing risk to public health, no approved vaccines or therapies exist for use in humans to prevent or combat WNV infection. The innate immune response is critical for controlling WNV replication, limiting virus-induced pathology, and programming protective humoral and cell-mediated immunity to WNV infection. The RIG-I like receptors, Toll-like receptors, and Nod-like receptors detect and respond to WNV by inducing a potent antiviral defense program, characterized by production of type I IFN, IL-1β and expression of antiviral effector genes. Recent research efforts have focused on uncovering the mechanisms of innate immune sensing, antiviral effector genes that inhibit WNV, and countermeasures employed by WNV to antagonize innate immune cellular defenses. In this review, we highlight the major research findings pertaining to innate immune regulation of WNV infection.

    We investigated mosquito and bird involvement in West Nile virus (WNV) transmission in July 2001 in Jefferson County, FL, and Lowndes County, GA. We detected 16 WNV-infected pools from Culex quinquefasciatus, Cx. salinarius, Cx. nigripalpus, and Culiseta melanura. In Florida, 11% of 353 bird sera neutralized WNV. Antibody prevalence was greatest in northern cardinal (Cardinalis cardinalis, 75%), northern mockingbird (Mimus polyglottus, 50%), common ground-dove (Columbina passerina, 25%), common grackle (Quiscalus quiscula, 15%), domestic chicken (Gallus gallus, 16%), and house sparrow (Passer domesticus, 11%). Antibody-positive birds were detected in nine of 11 locations, among which prevalence in chickens ranged from 0% to 100%. Seropositive chickens were detected in Georgia as well. The primary transmission cycle of WNV in the southeastern United States apparently involves Culex mosquitoes and passerine birds. Chickens are frequently infected and may serve as effective sentinels in this region.

  16. Potential for New York mosquitoes to transmit West Nile virus. (United States)

    Turell, M J; O'Guinn, M; Oliver, J


    We evaluated the potential for several North American mosquito species to transmit the newly introduced West Nile (WN) virus. Mosquitoes collected in the New York City Metropolitan Area during the recent (1999) WN outbreak were allowed to feed on chickens infected with WN virus isolated from a crow that had died during this outbreak. These mosquitoes were tested approximately 2 weeks later to determine infection, dissemination, and transmission rates. Culex pipiens mosquitoes were highly susceptible to infection, and nearly all individuals with a disseminated infection did transmit WN virus by bite. In contrast, Aedes vexans were only moderately susceptible to oral infection; however, those individuals inoculated with WN virus did transmit virus by bite.

Health workers are at high risk. The governments and WHO are responsible to provide necessary protective equipment to health workers dealing with Ebola. There is a strong need to identify the invisible chains of virus transmission. World Bank pledges$200 million to fight against Ebola, while WHO said$430 million are needed to control the Ebola outbreak. Ebola can be contained by early detection and isolation of case, contact tracing, monitoring of contacts and adaptation of rigorous procedures for virus control.

  18. Meat products and consumption culture in the West. (United States)

    Swatland, H J


    Meat products and consumption culture in the West may be traced back for at least 2,500 years. The dominant cultural source was Greco-Roman, with evidence from archeology, surviving documents and the names of meat cuts. The initial uniformity of meat technology and language in the Roman Empire was lost as national boundaries and languages fragmented. More recently, however, there has been a strong trend back to uniformity in meat cutting and grading. This started in the USA to solve logistical problems associated with long-distance commerce and similar changes occurred with the formation of the EU. Issues such as meat inspection and animal transport have been strongly influenced by the effect of literature on public opinion, which then led to legislated improvements. Innovations in other areas such as meat distribution and preservation had military origins. Meat consumption culture was involved in the early development of language, social grouping and religions.

    Talal Suleiman Mahmoud


    Full Text Available Cytotoxic activity of eight plant extracts, native from the Mid-West of Brazil comprising Cerrado, Pantanal and semideciduous forest, was evaluated for MDA-MB-435, SF-295, and HCT-8 cancer cell strains. A single 100 µg.mL-1 dose of each extract was employed with 72 h of incubation for all tests. Doxorubicin (1 µg.mL-1 was used as the positive control and the MTT method was used to detect the activity. Cytotoxicity of distinct polarities was observed in thirty extracts (46%, from different parts of the following species: Tabebuia heptaphylla (Vell. Toledo, Bignoniaceae, Tapirira guianensis Aubl., Anacardiaceae, Myracrodruon urundeuva Allemão, Anacardiaceae, Schinus terebinthifolius Raddi, Anacardiaceae, Gomphrena elegans Mart., Amaranthaceae, Attalea phalerata Mart. ex Spreng., Arecaceae, Eugenia uniflora L., Myrtaceae, and Annona dioica A. St.-Hil., Annonaceae. Extracts of at least two tested cell strains were considered to be highly active since their inhibition rate was over 75%.

    The severe Ebola virus disease epidemic occurring in West Africa stems from a single zoonotic transmission event to a 2-year-old boy in Meliandou, Guinea. We investigated the zoonotic origins of the epidemic using wildlife surveys, interviews, and molecular analyses of bat and environmental samples. We found no evidence for a concurrent outbreak in larger wildlife. Exposure to fruit bats is common in the region, but the index case may have been infected by playing in a hollow tree housing a colony of insectivorous free-tailed bats (Mops condylurus). Bats in this family have previously been discussed as potential sources for Ebola virus outbreaks, and experimental data have shown that this species can survive experimental infection. These analyses expand the range of possible Ebola virus sources to include insectivorous bats and reiterate the importance of broader sampling efforts for understanding Ebola virus ecology.

  1. The Different View of Privacy between China and the West

    Institute of Scientific and Technical Information of China (English)



    As a kind of cultural phenomena, privacy has different meaning in different culture. In the intercultural communica⁃tion, it is very important to have a correct view of privacy. This thesis compares and analyzes the privacy between China and the west in diverse angles. Based on the western scholar, privacy is a selective control of access to self or to one ’s group. Knowing the concept of privacy and the way to face the culture shock which followed by different view of privacy, we find some important things. That is, with the globalization of modern society, the common understanding on privacy will be more and the problems in the intercultural communication will be fewer if we understand and respect the other culture.

  3. Mitigation of floor heave in West Kentucky Coal Mine

    Institute of Scientific and Technical Information of China (English)

    Perry Kyle; Bradley Joel; Unrug Kot; Klimek Mark


    A West Kentucky mine operation in No. 11 seam encountered floor heave, due to the localized increase in the thickness of the fireclay mine floor. Floor heave has overridden seals installed in two mined out pan-els. The third seal’s location was planned for isolating that area from the Mains. A plan of support has been developed to prevent repetition of the floor heave and related problems outby the seals. The applied ground control measures were successful. An attempt of a 3D numerical modeling was made; thus, it would match the observed behavior of the mine floor and could be used as a design tool in similar con-ditions. The paper describes sequence of events, an applied mitigation ground control system, and the first stage of numerical modeling.

    Wind wave spectra were recorded simultaneously at three shallow (water depth 7–9 m) locations (Malpe, Honnavar and Karwar) along the 200 km stretch of the state of Karnataka in 2009 during 27 April–24 May (representing conditions prior to onset of the Indian summer monsoon), 12 June–8 July (monsoon), and 1–31 October (post-monsoon). Each spectrum was based on data recorded for half an hour using a waverider buoy. The paper describes characteristics of the spectra and the wave parameters derived from the spectra. Both reveal the dramatic changes that occur in the wave field due to the summer monsoon. The changes were virtually identical at all the three locations suggesting that the wave characteristics described here are representative of the conditions that exist along the coast of Karnataka State, west coast of India.

  6. Topographic data generated from Radarsat Images Over West Kalimantan, Indonesia

    Directory of Open Access Journals (Sweden)

    Ishak Hanafiah Ismullah


    Full Text Available Indonesia is a tropical country which has dominant cloud coverage, and some of the area has cloud cover almost all year long. Mapping by optical sensors, especially with Photogrammetric method shows a very good result, but the main constraint is cloud cover conditions, and this was the weakness point of this method.This study describe the technique for deriving Topographic data from Radarsat Synthetic Aperture Radar stereo image pair and apply it to an image pair over West Kalimantan, Indonesia. This paper contains also brief discussion of the use of stereo SAR to derive Digital Elevation Model, the site condition and the source of validation data. The result shows that Radarsat data recommended only for 1 : 100.000 or smaller.

  8. Use of Testing for West Nile Virus and Other Arboviruses (United States)

    Vanichanan, Jakapat; Salazar, Lucrecia; Wootton, Susan H.; Aguilera, Elizabeth; Garcia, Melissa N.; Murray, Kristy O.


    In the United States, the most commonly diagnosed arboviral disease is West Nile virus (WNV) infection. Diagnosis is made by detecting WNV IgG or viral genomic sequences in serum or cerebrospinal fluid. To determine frequency of this testing in WNV-endemic areas, we examined the proportion of tests ordered for patients with meningitis and encephalitis at 9 hospitals in Houston, Texas, USA. We identified 751 patients (567 adults, 184 children), among whom 390 (52%) experienced illness onset during WNV season (June–October). WNV testing was ordered for 281 (37%) of the 751; results indicated acute infection for 32 (11%). Characteristics associated with WNV testing were acute focal neurologic deficits; older age; magnetic resonance imaging; empirically prescribed antiviral therapy; worse clinical outcomes: and concomitant testing for mycobacterial, fungal, or other viral infections. Testing for WNV is underutilized, and testing of patients with more severe disease raises the possibility of diagnostic bias in epidemiologic studies. PMID:27537988

  9. Climate change unlikely to increase malaria burden in West Africa (United States)

    Yamana, Teresa K.; Bomblies, Arne; Eltahir, Elfatih A. B.


    The impact of climate change on malaria transmission has been hotly debated. Recent conclusions have been drawn using relatively simple biological models and statistical approaches, with inconsistent predictions. Consequently, the Intergovernmental Panel on Climate Change Fifth Assessment Report (IPCC AR5) echoes this uncertainty, with no clear guidance for the impacts of climate change on malaria transmission, yet recognizing a strong association between local climate and malaria. Here, we present results from a decade-long study involving field observations and a sophisticated model simulating village-scale transmission. We drive the malaria model using select climate models that correctly reproduce historical West African climate, and project reduced malaria burden in a western sub-region and insignificant impact in an eastern sub-region. Projected impacts of climate change on malaria transmission in this region are not of serious concern.

  10. Experimental Infections of Wild Birds with West Nile Virus

    Directory of Open Access Journals (Sweden)

    Elisa Pérez-Ramírez


    Full Text Available Avian models of West Nile virus (WNV disease have become pivotal in the study of infection pathogenesis and transmission, despite the intrinsic constraints that represents this type of experimental research that needs to be conducted in biosecurity level 3 (BSL3 facilities. This review summarizes the main achievements of WNV experimental research carried out in wild birds, highlighting advantages and limitations of this model. Viral and host factors that determine the infection outcome are analyzed in detail, as well as recent discoveries about avian immunity, viral transmission, and persistence achieved through experimental research. Studies of laboratory infections in the natural host will help to understand variations in susceptibility and reservoir competence among bird species, as well as in the epidemiological patterns found in different affected areas.

  12. Port Development and Town Planning in North West England (United States)

    Newman, Richard


    This paper examines the links between the development of harbour facilities and planned towns, especially in the head port area of Carlisle in North West England. Largely based on documentary research and field observation it examines the development of Whitehaven and other Atlantic ports it influenced in Cumberland, Westmorland and north Lancashire. It examines these developments in their international context and shows how they were initiated by local landowners to maximise the output of their estates and to enhance their personal prestige. Beginning in the seventeenth century the paper demonstrates how this tradition of town and harbour foundation continued on into the nineteenth century when it was adopted by corporate concerns, especially railway companies. The paper concludes by highlighting how harbour developments associated with town planning helped to urbanise and stimulate the economy of a previously under-developed area. Two maps identify the locations of the places discussed.

  13. The 17 July 2006 Tsunami earthquake in West Java, Indonesia (United States)

    Mori, J.; Mooney, W.D.; Afnimar,; Kurniawan, S.; Anaya, A.I.; Widiyantoro, S.


    A tsunami earthquake (Mw = 7.7) occurred south of Java on 17 July 2006. The event produced relatively low levels of high-frequency radiation, and local felt reports indicated only weak shaking in Java. There was no ground motion damage from the earthquake, but there was extensive damage and loss of life from the tsunami along 250 km of the southern coasts of West Java and Central Java. An inspection of the area a few days after the earthquake showed extensive damage to wooden and unreinforced masonry buildings that were located within several hundred meters of the coast. Since there was no tsunami warning system in place, efforts to escape the large waves depended on how people reacted to the earthquake shaking, which was only weakly felt in the coastal areas. This experience emphasizes the need for adequate tsunami warning systems for the Indian Ocean region.

  14. The epidemiology of inflammatory bowel diseases from West to East. (United States)

    Vegh, Zsuzsanna; Kurti, Zsuzsanna; Lakatos, Peter


    The incidence and prevalence of inflammatory bowel disease (IBD) show considerable variation over time and across geographic regions. The first studies on the epidemiology of IBD were available mainly from traditionally high-incidence areas, as North America and Northern and Western Europe. In the last two decades, more and more data have been reported from Eastern European and Asian counties with increasing incidence rates from some regions. According to recent studies, the high incidence and prevalence of IBD in some Western countries is plateauing and in some Eastern countries increasing incidence rates have been reported. In the era of "new", multicenter epidemiological studies with common methodology the direct comparison of incidence and prevalence rates became possible. In the present review we would like to summarize the currently available literature on the West-East differences in the incidence and prevalence rates of IBD.

  15. Remote sensing needs and capabilities in West Africa

    Institute of Scientific and Technical Information of China (English)

    Edward M.Osei,Jr.


    The greatest advantage of remote sensing over conventional measurements lies in the opportunity to carry out detailed spatio-temporal analysis of land and ocean features on a very frequent basis. This paper analyses the contribution of satellite imagery to atmospheric, geophysical and ocean studies and management in West Africa since the early 1980s.The detailed application of data from optical sensors (e.g. Meteosat,NOAA/AVHRR, SPOT,L andsat TM, etc.) for weather prediction, hydrogeological, landuse/cover and cartographic studies has been acknowledged. However, the use of microwave (e.g. SAR) and optical data for ocean monitoring and studies in the sub-region is still very limited. Even though sufficient remote sensing expertise and infrastructure is perceived in the region, no clearly defined networking or database exists.

  16. Putting farmers first: reshaping agricultural research in West Africa

    Energy Technology Data Exchange (ETDEWEB)

    Pimbert, Michel


    How agricultural research is funded, organised, controlled and practised can have a huge impact on small-scale producers in the global South. In many countries, such research is driven by external funds, priorities and technological fixes, such as hybrid seeds, which can erode crop diversity. But food producers across the world are beginning to raise their voices to ensure that agricultural research better meets their needs and priorities. A series of farmer assessments and citizens' juries in West Africa has helped farmers assess existing approaches and articulate recommendations for policy and practice to achieve their own vision of agricultural research. In 2012, a high-level policy dialogue between farmers and the Alliance for a Green Revolution in Africa hopes to take this discussion to the next level and develop a shared agenda that can serve development and the public good.

  17. [A brief history of hospital development in the West]. (United States)

    Fang, Chongliang; Liu, Piyan; Jiang, Guiying


    Origin and development of hospital in the West was related closely with religions and wars. Before the Medieval Ages, priests or physicians treated their patients mainly in temples, which may be regarded as the earliest type of hospital. The military hospital first appeared in the ancient Rome due to war. During the Medieval Ages, most hospitals were attached to monasteries. The Crusades prompted the development of hospitals and hospices along the route taken by the Crusaders. After the Medieval Ages, as the Protestantism rose, the monastic hospitals suffered a major setback and secular hospitals developed. From the 16th century, hospitals of Europe were spread gradually into North America. During the 18th and 19th centuries, function of hospital in medical treatment, education and research was strengthened gradually. In the 20th century, hospital facilities were matured technically and management of hospital became an important problem to which people devoted themselves to resolve it.

  18. Atlantic forcing of persistent drought in West Africa. (United States)

    Shanahan, T M; Overpeck, J T; Anchukaitis, K J; Beck, J W; Cole, J E; Dettman, D L; Peck, J A; Scholz, C A; King, J W


    Although persistent drought in West Africa is well documented from the instrumental record and has been primarily attributed to changing Atlantic sea surface temperatures, little is known about the length, severity, and origin of drought before the 20th century. We combined geomorphic, isotopic, and geochemical evidence from the sediments of Lake Bosumtwi, Ghana, to reconstruct natural variability in the African monsoon over the past three millennia. We find that intervals of severe drought lasting for periods ranging from decades to centuries are characteristic of the monsoon and are linked to natural variations in Atlantic temperatures. Thus the severe drought of recent decades is not anomalous in the context of the past three millennia, indicating that the monsoon is capable of longer and more severe future droughts.

  19. Preliminary disease surveillance in west Texas quail (galliformes: odontophoridae) populations. (United States)

    Urban, Kristyn N; Gibson, Anna G; Dabbert, C Brad; Presley, Steven M


    Northern Bobwhite (Colinus virginianus) and Scaled Quail (Callipepla squamata) occur throughout northwestern Texas and overall population numbers have been declining for the past 30 yr. This decline has been attributed to habitat loss associated with intensive agricultural practices. We propose that disease may be a contributing factor to decline. Our findings suggest that West Nile virus (WNV) infection may be common in wild quail populations on the Rolling Plains of northwestern Texas. Serum samples (n=301) from wild-caught Northern Bobwhite and Scaled Quail were collected during 2008-10 from seven private properties across the Rolling Plains Region; 5.3% had detectable antibodies against WNV using an enzyme-linked immunosorbent assay. To our knowledge, this is the first report of antibodies to WNV in Scaled Quail and wild-caught Northern Bobwhite from the Rolling Plains of Texas.

  20. Ebola outbreak in West Africa: a neglected tropical disease

    Institute of Scientific and Technical Information of China (English)

    Alcides; Troncoso


    Neglected tropical diseases(NTDs) are remediable injustices of our times. Poverty is the starting point, and the ultimate outcome, of NTD. Ebola is just one of many NTDs that badly need attention. Ebola exacerbates West Africa’s poverty crisis. The virus spreading in Guinea,Liberia and Sierra Leone has led to food shortages and neglect of other devastating tropical illnesses. A health crisis that was ignored for months until it was out of control is now beginning to get the attention required, if not the resources. So far, the world′s nations have contributed far less than the $ 1 billion. The U.N. estimates would need to control the epidemic before it becomes endemic. Past outbreaks of Ebola have flared up in remote, forested communities, disconnected from much of the outside world. But the outbreak in West Africa has not slowed yet, and it worsens there the chances of it spreading to other countries. Ebola draws attention to NTD. Ebola is not only a health emergency, but also it′s a poverty crisis.The current Global Ebola crisis presents a multitude of challenges in terms of our capacity to respond; the future is even less predictable. Ebola outbreak represents inequity in health as the occurrence of health differences considered unnecessary, avoidable, unfair, and unjust, thus adding a moral and ethical dimension to health inequalities. Health equity does not refer only to the fairness in the distribution of health or the provision of health care; rather, it is linked with the larger issues of fairness and justice in social arrangements.
