    Two new triterpene glycosides, scabraside A (1) and B (2), and a structurally known compound (3), were isolated from the sea cucumber Holothuria scabra (Holothuriidae) collected from the South China Sea. Structure of these compounds was elucidated by spectroscopic and chemical methods. The glycosides 1 and 2 exhibit the same common structural features, i. e., the presence of 12- and 17-hydroxy groups in the holostane-type triterpene aglycone with a 9(11)-ene bond, but are different in the side chains of the triterpene aglycone. The glycosides 1 and 2 had significant in vitro cytotoxicity against four human tumor cell lines in comparison to 10-hydroxycamptothecin. PMID:19598081

    Bioactive compounds of the gonad, respiration tree, and body wall of the sea cucumber Holothuria scabra collected from the North Coast of the Persian Gulf were extracted using ethyl acetate, methanol and water-methanol mixtures. Extracts were evaluated for their antibacterial and antifungal activities against Aspergillus niger, Candida albicans, Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli. The activity was determined using the disc diffusion test. Cytotoxic activities of the extracts were determined by brine shrimp lethality assay. Results showed the existence of an antifungal activity of all extracts against A. niger with MIC ranging from 3 to 9?g/mL. The highest antifungal activity was found in respiration tree (methanol) with an inhibition zone of about 50mm against A. niger at 18?g/mL extract concentration. Cytotoxic activity was obtained for methanolic extracts only. Methanol extract of the gonads showed the highest cytotoxic effect (LC50=50.5?g/mL) continuing with RT methanol extract (LC50=70?g/mL).

    Populations of Holothuria scabra at Abu Rhamada Island were investigated during 52 months, from July 1999 to October 2003. During the first 23 months (July, 1999-May, 2001) the Island had a robust population with a tri-modal size frequency distribution curve, very high densities (85.7-95.1 ind./100 m2 at the sandy habitat), high abundance (3362-3110 individuals) and biomass (46.7-34.3 kg/100 m2). Also, during this period most individuals were at depths between 4 and 6m and no individuals were recorded deeper than 15m. The population declined after harvesting began (June, 2001) and by March, 2002 the size frequency distribution showed a bimodal pattern with an obvious decrease in abundance of large individuals. There was also a slight reduction in densities (73.2-60.1 ind./100 m2 at the sandy habitat), abundance (2292-1682 individuals) and biomass (21.6-11.3 kg/100 m2), and a marked shift towards deeper waters. Overfishing reached its maximum during the final 19 months of the study, and by October, 2003, density (30.7-0.4 ind./100 m2 at the sandy habitat), abundance (802-10 individuals) and biomass (6.9-0.1 kg/100 m2) were all greatly reduced. The size frequency distribution of the population became unimodal, large animals disappeared and no recruits were seen. During this period, individuals were found at very deep depths (30 to >40 m). The study also showed that sandy substrate was the preferred habitat for H. scabra, accommodating the largest number of individuals. The population of H. scabra at Abu Rhamada Island was found to spawn biannually from 1999 to 2001, then only once during 2002 when high fishing pressure occurred, and ceased completely in 2003. The sex ratio was not significantly different from 1:1 before fishing begun, but shifted to an increasing male bias reaching 93% males by January 2003. None of the small animals remaining after January, 2003 could be sexed. Size at sexual maturity decreased from prefishing (185 mm for females and 160 mm for males) to 155 mm for females and 125 mm for males in January 2003. There was a positive relationship between fecundity and size. And oocyte/female was highest in 1999 (0.73-1.7 million) and 2000 (0.75-1.72 million), decreased during 2001 (0.2-0.85 million) to reach its minimum at 2002 (0.28-0.29 million). PMID:15924996

    Holothuria scabra produces a monomeric lectin (HSL) of 182 kDa. HSL showed strong antibacterial activity and induced bacterial agglutination under in vitro conditions, indicating its role in animals' innate immune responses. Very few lectins have been reported from echinoderms and none of these lectins have been explored in detail for their sugar-binding kinetics. Affinity, kinetics and thermodynamic analysis of glycans and glycoproteins binding to HSL were studied by fluorescence and surface plasmon resonance spectroscopy. Lectin binds with higher affinity to O-linked than N-linked asialo glycans, and the affinities were relatively higher than that for sialated glycans and glycoproteins. T-antigen ?-methyl glycoside was the most potent ligand having the highest affinity (Ka 8.32 ×10(7) M(-1)). Thermodynamic and kinetic analysis indicated that the binding of galactosyl Tn-antigen and asialo glycans is accompanied by an enthalpic contribution in addition to higher association rate coupled by low activation energy for the association process. Presence of sialic acid or protein matrix inhibits binding. Higher affinity of HSL for O-glycans than N-glycans had biological implications; since HSL specifically recognizes bacteria, which have mucin or O-glycan cognate on their cell surfaces and play a major role in animal innate immunity. Since, HSL had higher affinity to T-antigen, makes it a useful tool for cancer diagnostic purpose. PMID:23736907

    A novel lectin was purified from the coelomic fluid of the sea cucumber Holothuria scabra (HSL), subjected to bacterial challenge. HSL is a monomeric glycoprotein of molecular mass 182 kDa. The lectin is highly thermostable as it retains full activity for 1 h at 80 degrees C. Further, the hemagglutination activity of HSL is unaffected by pH in the range 2-11. Unlike other lectins purified from marine invertebrates, the hemagglutination activity of HSL does not require any divalent metal ions. The affinity profile of HSL was studied by a combination of hemagglutination inhibition and fluorescence spectroscopy. HSL binds to desialylated glycoproteins, MealphaGal, T-antigen and T (alpha-ser)-antigen with a distinction between beta1-4 and beta1-3 linkages. Mealpha-T-antigen was a potent ligand having highest affinity (Ka 8.32 x 10(7)M(-1)). Monosaccharide binding is enthalphically driven while disaccharide binding involves both entropic and enthalpic contributions. PMID:18282768

    Gentianae Scabrae Radix is a well-known traditional medicine that is used for the treatment of hepatitis, cholecystitis and inflammatory diseases. It consists mainly of secoiridoid glycosides, with representatives of gentiopicroside, sweroside and swertiamarin. In the present study, a chemical investigation of the CHCl3 extract of Gentianae Scabrae Radix derived from Gentiana scabra Bunge yielded seven new (1-7) and ten known (8-17) secoiridoid glycosides. Their structures were elucidated by extensive spectroscopic analyses and comparison with literature data. All 17 compounds were evaluated for their inhibitory effects against NO, IL-6 and TNF-? productions induced by lipopolysaccharide (LPS) in RAW264 cells. Among them, 8-epi-kingiside derivatives 1-3; kingiside derivatives 4, 5 and 10; and a sweroside derivative 6 showed inhibition activity against IL-6 production with IC50 values of 51.70-61.10 ?M, whereas sweroside derivatives 12 and 15-17 and a swertiamarin derivative 13 showed inhibition effects on both NO and IL-6 productions with IC50 values of 64.74-94.95 and 48.91-75.45 ?M, respectively. All the compounds exhibited weak inhibitory activity (IC50 > 100 ?M) in a TNF-? bioassay. Finally, a primary structure-activity relationship of these secoiridoid glycosides is discussed.

    Knowledge of heat-responsive proteins is critical for further understanding of the molecular mechanisms of heat tolerance. The objective of this study was to compare proteins differentially expressed in two C(3) grass species contrasting in heat tolerance, heat-tolerant thermal Agrostis scabra and heat-sensitive Agrostis stolonifera L., and to identify heat-responsive proteins for short- and long-term responses. Plants were exposed to 20/15 degrees C (day/night, control) or 40/35 degrees C (day/night, heat stress) in growth chambers. Leaves were harvested at 2 and 10 days after temperature treatment. Proteins were extracted and separated by fluorescence difference gel electrophoresis (DIGE). Thermal A. scabra had superior heat tolerance than A. stolonifera, as indicated by the maintenance of higher chlorophyll content and photochemical efficiency under heat stress. The two-dimensional difference electrophoresis detected 68 heat-responsive proteins in the two species. Thermal A. scabra had more protein spots either down- or up-regulated at 2 days of heat stress, but fewer protein spots were altered at 10 days of heat stress compared with A. stolonifera. Many protein spots exhibited transient down-regulation in thermal A. scabra (only at 2 days of heat treatment), whereas down-regulation of many proteins was also found at 10 days of heat treatment in A. stolonifera, which suggested that protein metabolism in thermal A. scabra might acclimate to heat stress more rapidly than those in A. stolonifera. The sequences of 56 differentially expressed protein spots were identified using mass spectrometry. The results suggest that the maintenance or less severe down-regulation of proteins during long-term (10 days) heat stress may contribute to the superior heat tolerance in thermal A. scabra, including those involved in photosynthesis [RuBisCo, RuBisCo activase, chloroplastic glyceraldehydes-3-phosphate dehydrogenase (GAPDH), chloroplastic aldolase, oxygen-evolving complex, photosystem I subunits], dark respiration (cytosolic GAPDH, cytoplasmic aldolase, malate dehydrogenase, hydroxypyruvate reductase, sedoheptulose-1,7-bisphosphatase), photorespiration [(hydroxypyruvate reductase, alanine aminotransferase (AlaAT), hydroxymethyltransferase (SHMT), glycine decarboxylase (GDC)], as well as heat and oxidative stress protection [heat shock cognate (HSC) 70 and FtsH-like protein].

    Background: Emergence of antimicrobial resistance toward a number of conventional antibiotics has triggered the search for antimicrobial agents from a variety of sources including the marine environment. Objectives: The aim of this study was to evaluate the antimicrobial potential of Holothuria leucospilota from Qeshm and Kharg Islands against some selected bacteria and fungi. Materials and Methods: In this investigation, sea cucumbers from two coastal cities of Persian Gulf were collected in March and May 2011 and identified by the scale method according to the food and agriculture organization of the United Nations. Antibacterial activity of hydroalcoholic extracts of the body wall, cuvierian organs and coelomic fluid, methanol, chloroform, and n-hexane extracts of the body wall were evaluated by the spot test. In addition, their antifungal activity was assessed by the broth dilution method. Results: The displayed effect was microbiostatic at concentrations of 1000 and 2000 µg/mL rather than microbicidal. The highest activity of hydroalcoholic extracts was exhibited by body wall, cuvierian organs and coelomic fluid against Escherichia coli, Salmonella typhi, Staphylococcus aureus and Pseudomonas aeruginosa; Aspergillus niger, A. fumigatus, A. flavus and A. brasilensis. However, none of the methanol, chloroform and n-haxane extracts showed appreciable effects against Shigella dysenteriae, Proteus vulgaris, Bacillus cereus, S. epidermidis and Candida albicans. Moreover, cuvierian organs did not possess any antifungal potential. Conclusions: Our data indicated that water-methanol extracts from the body wall of H. leucospilota possess antibacterial and antifungal activity. However, additional and in-depth studies are required to isolate and identify the active component(s). PMID:25147657

    A novel, Gram-positive bacterial strain, F12(T), was isolated from the abdominal epidermis of a sea cucumber, Holothuria edulis, collected from seawater off the coast of Japan. According to 16S rRNA gene sequence analysis, this strain represents a novel, deep-rooting lineage within the class Actinobacteria and clusters with uncultured bacteria and Acidimicrobium ferrooxidans. Compared to species with validly published names, the highest 16S rRNA gene sequence similarity (89.8 %) was to Acidimicrobium ferrooxidans DSM 10331(T). Phylogenetic analyses showed that strain F12(T) represents a distinct phylogenetic lineage related closely to the genus Acidimicrobium. Strain F12(T) contained MK-9(H(6)) as the major menaquinone, whilst 17 : 0, 17 : 1omega8c, 15 : 0 and 16 : 0 were the major cellular fatty acids. The cell-wall peptidoglycan of strain F12(T) was composed of meso-diaminopimelic acid as the diagnostic diamino acid, alanine and glutamic acid (1 : 2 : 1). The cell-wall sugars detected were rhamnose, mannose, arabinose, galactose and xylose. The G+C content of the DNA was 74.4 mol%. From the taxonomic data obtained in this study, the name Iamia majanohamensis gen. nov., sp. nov. is proposed for the isolate, with type strain F12(T) (=NBRC 102561(T)=DSM 19957(T)). The name Iamiaceae fam. nov. is also proposed for the distinct phyletic line represented by the genus Iamia. PMID:19329622

    ABSTRACT This study examines the relative importance of canopy size and induced resistance to Colletotrichum gloeosporioides at 350- and 700-ppm atmospheric CO(2) concentrations on susceptible Stylosanthes scabra 'Fitzroy' from two studies in a controlled environment facility (CEF) and in the field. Plants were grown at the two CO(2) concentrations in a repeated experiment in the CEF and inoculated at 6, 9, or 12 weeks of age. Although the physiological maturity of plants was at a similar stage for all three ages, the number of lesions per plant increased with increasing plant age at both CO(2) concentrations. At 350 ppm, the increase was associated with canopy size and increasing infection efficiency of the pathogen, but at 700 ppm, it was associated only with canopy size, because infection efficiency did not change with increasing age. A level of resistance was induced in plants at 700 ppm CO(2). In a second study, plants were raised for 12 to 14 weeks at the two CO(2) concentrations in the CEF and exposed to C. gloeosporioides inoculum in replicated field plots under ambient CO(2) over three successive years. Fitzroy developed a dense and enlarged canopy, with 28 to 46% more nodes, leaf area, and aboveground biomass at high CO(2) than at low CO(2). Up to twice as many lesions per plant were produced in the high CO(2) plants, because the enlarged canopy trapped many more pathogen spores. The transient induced resistance in high CO(2) plants failed to operate when exposed to pathogen inoculum under ambient CO(2) in the field. These results highlight the need to consider both canopy size and host resistance in assessing the influence of elevated CO(2) on plant disease. PMID:18943969

    Wound repair is a key event in the regeneration mechanisms of echinoderms. We studied, at the behavioural, cellular and molecular levels, the wound healing processes in Holothuria tubulosa after injuries to the body wall. The experiments were performed for periods of up to 72 h, and various coelomocyte counts, as well as the expression of heat shock proteins (HS27, HSP70 and HSP90), were recorded. Dermal wound healing was nearly complete within 72 h. In the early stages, we observed the injured animals twisting their bodies to keep their injuries on the surface of the water for the extrusion of the buccal pedicles. At the cellular level, we found time-dependent variations in the circulating coelomocyte counts. After injury, in particular, we observed a significant increase in spherule cells at 2.5 h post-injury. Using the western blot method, we observed and reported that the wounds produced, compared with controls, a significant increase in HSP27 and HSP70 expression in coelomocytes, whereas HSP70 was increased in scar tissue and HSP90 was increased only in cell-free coelomic fluid. These results highlight that the wounds were responsible for the stress condition with the induction of cellular and biochemical responses. PMID:25463287

    Among higher metazoans, echinoderms exhibit the most impressive capacity for regeneration. Holothurians, or sea cucumbers, respond to adverse stimuli by autotomizing and ejecting their visceral organs, which are then regenerated. Neuronal fibers and cell bodies are present within the viscera, but previous regeneration studies have not accounted for the nervous component. We used light microscopic immunocytochemistry and ultrastructural studies to describe the regeneration of the enteric nervous system in the sea cucumber Holothuria glaberrima. This study provides evidence that the enteric nervous system of this echinoderm regenerates after evisceration and that in 3-5 weeks the regenerated system is virtually identical to that of noneviscerated animals. The regeneration of the enteric nervous system occurs parallel to the regeneration of other organ components. Nerve fibers and cells are observed within the mesenterial thickenings that give rise to the new intestine and within the internal connective tissue prior to lumen formation. We also used bromodeoxyuridine incorporation to show that proliferation of the neuronal population occurs in the regenerating intestine. The regeneration of the nervous system commands high interest because members of the closely related phylum Chordata either lack or have a very limited capacity to regenerate their nervous system. Thus, holothurians provide a model system to study enteric nervous system regeneration in deuterostomes. PMID:10205023

    Echinoderms are a key group in understanding the evolution of the nervous system in the Metazoa. Remarkably, little is known about echinoderm neurobiology. The echinoderm podia, which are unique echinoderm modifications and comprise structures responsible for locomotion and feeding, have been largely neglected in nervous system studies. Here, we have applied immunohistological approaches using different neuronal markers to describe the neuroanatomy of the holothurian podia and its relation to the muscular component. We show, using the sea cucumber Holothuria glaberrima (Selenka, 1867), the direct innervation of the podia by the ectoneural component of the nervous system, as well as the existence of a connection between the nervous system components in the main nerves, the muscle, and the connective tissue. These findings confirm the ectoneural origin of the tube feet's main nervous system and demonstrate its neuroanatomic complexity. We also show the presence of fibers and neurons within the tube feet mesothelium and connective tissue. The study of these simple structures will help us elucidate the echinoderms' neuromuscular circuit and their evolutionary relationships. PMID:20461218

    The sea cucumber Holothuria forskåli possesses a specialized system called Cuvierian tubules. During mechanical stimulation white filaments (tubules) are expelled and become sticky upon contact with any object. We isolated a protein with adhesive properties from protein extracts of Cuvierian tubules from H. forskåli. This protein was identified by antibodies against recombinant precollagen D which is located in the byssal threads of the mussel Mytilus galloprovincialis. To find out the optimal procedure for extraction and purification, the identified protein was isolated by several methods, including electroelution, binding to glass beads, immunoprecipitation, and gel filtration. Antibodies raised against the isolated protein were used for localization of the adhesive protein in Cuvierian tubules. Immunostaining and immunogold electron microscopical studies revealed the strongest immunoreactivity in the mesothelium; this tissue layer is involved in adhesion. Adhesion of Cuvierian tubule extracts was measured on the surface of various materials. The extracted protein showed the strongest adhesion to Teflon surface. Increased adhesion was observed in the presence of potassium and EDTA, while cadmium caused a decrease in adhesion. Addition of antibodies and trypsin abolished the adhesive properties of the extract. PMID:22013488

    The sea cucumber Holothuria leucospilota has high me-dicinal value and rich nutritional edible value, and thus is a commercially important aquatic product in China. Microsatellite loci were developed and screened using a fast isolation protocol and amplified fragment length polymorphism of sequences containing repeats. In this study, 16 novel polymorphic microsatellite markers in H. leucospilota were identified, and the relevant genetic variability index was assessed using 30 individu-als from a wild population. The polymorphic information content ranged from 0.183 to 0.668, and the number of alleles per locus varied from 3 to 5. The observed and expected heterozygosities were 0.0370-0.5000 and 0.0776-0.6250, respectively. With the exception of 3 loci (Y1-15, Y11-1, and Y28), the polymorphic loci were in Hardy-Weinberg equilibrium (P > 0.003125). These polymorphic microsatellite loci will contribute to studies of genetic diversity, the research of population structure, and the design of conservation strategies for H. leucospilota.

    Sea cucumbers, sometimes referred to as marine ginseng, produce numerous compounds with diverse functions and are potential sources of active ingredients for agricultural, nutraceutical, pharmaceutical and cosmeceutical products. We examined the viscera of an Australian sea cucumber Holothuria lessoni Massin et al. 2009, for novel bioactive compounds, with an emphasis on the triterpene glycosides, saponins. The viscera were extracted with 70% ethanol, and this extract was purified by a liquid-liquid partition process and column chromatography, followed by isobutanol extraction. The isobutanol saponin-enriched mixture was further purified by high performance centrifugal partition chromatography (HPCPC) with high purity and recovery. The resultant purified polar samples were analyzed using matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS)/MS and electrospray ionization mass spectrometry (ESI-MS)/MS to identify saponins and characterize their molecular structures. As a result, at least 39 new saponins were identified in the viscera of H. lessoni with a high structural diversity, and another 36 reported triterpene glycosides, containing different aglycones and sugar moieties. Viscera samples have provided a higher diversity and yield of compounds than observed from the body wall. The high structural diversity and novelty of saponins from H. lessoni with potential functional activities presents a great opportunity to exploit their applications for industrial, agricultural and pharmaceutical use.

    Sea cucumbers are prolific producers of a wide range of bioactive compounds. This study aimed to purify and characterize one class of compound, the saponins, from the viscera of the Australian sea cucumber Holothuria lessoni. The saponins were obtained by ethanolic extraction of the viscera and enriched by a liquid-liquid partition process and adsorption column chromatography. A high performance centrifugal partition chromatography (HPCPC) was applied to the saponin-enriched mixture to obtain saponins with high purity. The resultant purified saponins were profiled using MALDI-MS/MS and ESI-MS/MS which revealed the structure of isomeric saponins to contain multiple aglycones and/or sugar residues. We have elucidated the structure of five novel saponins, Holothurins D/E and Holothurinosides X/Y/Z, along with seven reported triterpene glycosides, including sulfated and non-sulfated saponins containing a range of aglycones and sugar moieties, from the viscera of H. lessoni. The abundance of novel compounds from this species holds promise for biotechnological applications. PMID:25110919

    Repair and regeneration are key processes for tissue maintenance, and their disruption may lead to disease states. Little is known about the molecular mechanisms that underline the repair and regeneration of the digestive tract. The sea cucumber Holothuria glaberrima represents an excellent model to dissect and characterize the molecular events during intestinal regeneration. To study the gene expression profile, cDNA libraries were constructed from normal, 3-day, and 7-day regenerating intestines of H. glaberrima. Clones were randomly sequenced and queried against the nonredundant protein database at the National Center for Biotechnology Information. RT-PCR analyses were made of several genes to determine their expression profile during intestinal regeneration. A total of 5,173 sequences from three cDNA libraries were obtained. About 46.2, 35.6, and 26.2% of the sequences for the normal, 3-days, and 7-days cDNA libraries, respectively, shared significant similarity with known sequences in the protein database of GenBank but only present 10% of similarity among them. Analysis of the libraries in terms of functional processes, protein domains, and most common sequences suggests that a differential expression profile is taking place during the regeneration process. Further examination of the expressed sequence tag dataset revealed that 12 putative genes are differentially expressed at significant level (R > 6). Experimental validation by RT-PCR analysis reveals that at least three genes (unknown C-4677-1, melanotransferrin, and centaurin) present a differential expression during regeneration. These findings strongly suggest that the gene expression profile varies among regeneration stages and provide evidence for the existence of differential gene expression. PMID:17579180

    Metazoan immunity is mainly associated with specialized cells that are directly involved with the immune response. Nevertheless, both in vertebrates and invertebrates other organs might respond to immune activation and participate either directly or indirectly in the ongoing immune process. However, most of what is known about invertebrate immunity has been restricted to immune effector cells and little information is available on the immune responses of other tissues or organs. We now focus on the immune reactions of the intestinal tissue of an echinoderm. Our study employs a non-conventional model, the echinoderm Holothuria glaberrima, to identify intestinal molecules expressed after an immune challenge presented by an intra-coelomic injection of lipopolysaccharides (LPS). The expression profiles of intestinal genes expressed differentially between LPS-injected animals and control sea water-injected animals were determined using a custom-made Agilent microarray with 7209 sea cucumber intestinal ESTs. Fifty (50) unique sequences were found to be differentially expressed in the intestine of LPS-treated sea cucumbers. Seven (7) of these sequences represented homologues of known proteins, while the remaining (43) had no significant similarity with any protein, EST or RNA database. The known sequences corresponded to cytoskeletal proteins (Actin and alpha-actinin), metabolic enzymes (GAPDH, Ahcy and Gnmt), metal ion transport/metabolism (major yolk protein) and defense/recognition (fibrinogen-like protein). The expression pattern of 11 genes was validated using semi-quantitative RT-PCR. Nine of these corroborated the microarray results and the remaining two showed a similar trend but without statistical significance. Our results show some of the molecular events by which the holothurian intestine responds to an immune challenge and provide important information to the study of the evolution of the immune response.

    Fucosylated chondroitin sulfate (fCS) extracted from the sea cucumber Holothuria forskali is composed of the following repeating trisaccharide unit: ?3)GalNAc?4,6S(1?4) [Fuc?X(1?3)]GlcA?(1?, where X stands for different sulfation patterns of fucose (X = 3,4S (46%), 2,4S (39%), and 4S (15%)). As revealed by NMR and molecular dynamics simulations, the fCS repeating unit adopts a conformation similar to that of the Lex blood group determinant, bringing several sulfate groups into close proximity and creating large negative patches distributed along the helical skeleton of the CS backbone. This may explain the high affinity of fCS oligosaccharides for L- and P-selectins as determined by microarray binding of fCS oligosaccharides prepared by Cu2+-catalyzed Fenton-type and photochemical depolymerization. No binding to E-selectin was observed. fCS poly- and oligosaccharides display low cytotoxicity in vitro, inhibit human neutrophil elastase activity, and inhibit the migration of neutrophils through an endothelial cell layer in vitro. Although the polysaccharide showed some anti-coagulant activity, small oligosaccharide fCS fragments had much reduced anticoagulant properties, with activity mainly via heparin cofactor II. The fCS polysaccharides showed prekallikrein activation comparable with dextran sulfate, whereas the fCS oligosaccharides caused almost no effect. The H. forskali fCS oligosaccharides were also tested in a mouse peritoneal inflammation model, where they caused a reduction in neutrophil infiltration. Overall, the data presented support the action of fCS as an inhibitor of selectin interactions, which play vital roles in inflammation and metastasis progression. Future studies of fCS-selectin interaction using fCS fragments or their mimetics may open new avenues for therapeutic intervention. PMID:25147180

    This preliminary study aimed to identify a commercial gamat species, Stichopus horrens Selenka, 1867, and a timun laut species, Holothuria (Mertensiothuria) leucospilota (Brandt, 1835), from Pangkor Island, Perak, Malaysia, employing morphological techniques based on the shape of the ossicles and molecular techniques based on the cytochrome c oxidase I (COI) mitochondrial DNA (mtDNA) gene. In Malaysia, a gamat is defined as a sea cucumber species of the family Stichopodidae with medicinal value, and timun laut refers to non-gamat species. S. horrens is very popular on Pangkor Island as a main ingredient in the traditional production of air gamat and minyak gamat, while H. leucospilota is the most abundant species in Malaysia. In contrast to previous studies, internal body parts (the respiratory tree and gastrointestine) were examined in this study to obtain better inferences based on morphology. The results showed that there were no ossicles present in the gastrointestine of H. leucospilota, and this characteristic is suggested as a unique diagnostic marker for the timun laut species. In addition, the presence of Y-shaped rods in the respiratory tree of S. horrens subsequently supported the potential to use internal body parts to identify the gamat species. Phylogenetic analysis of the COI mtDNA gene of the sea cucumber specimens using the neighbour-joining method and maximum likelihood methods further confirmed the species status of H. leucospilota and S. horrens from Pangkor Island, Perak, Malaysia. The COI mtDNA gene sequences were registered with GenBank, National Center for Biotechnology Information (NCBI), US National Library of Medicine (GenBank accession no.: KC405565-KC405568). Although additional specimens from various localities will be required to produce more conclusive results, the current findings provide better insight into the importance of complementary approaches involving morphological and molecular techniques in the identification of the two Malaysian sea cucumber species.

Walp (cowpea), Desmodium uncinatum (silverleaf desmodium), Stylosanthes guianensis (oxley fine stem stylo) and Stylosanthes scabra (fitzroy) and of natural pasture (veld) hay were analysed and ranked according to their proanthocyanidin (PA) and saponin content. Silverleaf desmodium and fitzroy leaf and stem samples of different ages were also separately analysed for the PA contents. All the samples analysed contained some PA but no saponins. High levels of PA were detected in silverleaf desmodium and very low levels in veld hay and cowpea. In all samples, more of the tannins were bound to protein or neutral detergent fibre (NDF) than were extractable, most being bound to proteins. The proportion of the unextractable PA was greater in younger than in mature materials. PMID:11234193

    The snail, Littoraria scabra, is a dominant grazer on tropical mangrove trees, and may play an important role in the food web dynamics of these ecosystems. Its daily vertical migration to avoid tidal submersion results in exposure to varying food types and abundances. A comprehensive diet analysis - gut contents, fatty acid profiles, and stable isotopes ( ?15N and ?13C) - was conducted on snails migrating along mangrove trees and snails maintained in non-tidal mesocosms at Nananu-i-ra, Fiji Islands. In addition, fatty acid profiles and stable isotope signatures were obtained from surface scrapings of mangrove roots, trunks, branches, and leaves. Results from this multi-technique study indicate that L. scabra is mainly a generalist herbivore, which easily shifts diets depending on food availability, and which also has the ability to ingest and assimilate zooplankton. Ingestion of greater quantities of diverse foods (i.e., microalgae, foliose/corticated macrophytes, filamentous algae, mangrove tissues, zooplankton) takes place in the bottom areas of mangrove trees (roots and trunks) during low tides, while top areas (branches and leaves) provide limited food resources for snails feeding during high tides. However, snails preferentially assimilate microalgae and bacteria, regardless of their feeding habitat (different areas within mangrove trees and non-tidal mesocosms). The daily vertical movements of this snail result in variable feeding times, ingestion of different food types and amounts, and different assimilations. These findings also suggest that organic matter derived from mangrove tissues may not be readily transferred to higher trophic levels through this grazing pathway.

    Oxidative stress is a common mechanism contributing to the initiation and progression of hepatic damage. Hence there is a great demand for the development of agents with potent antioxidant effect. The aim of the present study is to evaluate the efficacy of Holothuria atra extract (HaE) as an antioxidant against 7,12-dimethylbenz[a]anthracene- (DMBA-) induced hepatorenal dysfunction. Experimental animals were divided into two main groups: protective and curative. Each group was then divided into five subgroups pre- or posttreated either with distilled water (DMBA subgroups) or with HaE (200?mg/kg body weight) for seven and fourteen days. Single oral administration of DMBA (15?mg/kg body weight) to Wistar rats resulted in a significant increase in the serum liver enzymes and kidney function's parameters. DMBA increased level of liver malondialdehyde (MDA), decreased levels of reduced glutathione (GSH), glutathione-S-transferase (GST), superoxide dismutase (SOD), and catalase (CAT) in the liver tissue, and induced liver histopathological alterations. Pre- or posttreatment with HaE orally for 14 days significantly reversed the hepatorenal alterations induced following DMBA administration. In conclusion, HaE exhibits good hepatoprotective, curative, and antioxidant potential against DMBA-induced hepatorenal dysfunction in rats that might be due to decreased free radical generation.

    Two peptides, Gly-Phe-Ser-Lys-Leu-Tyr-Phe-NH2 (GFSKLYFamide) and Ser-Gly-Tyr-Ser-Val-Leu-Tyr-Phe-NH2 (SGYSVLYFamide), recently isolated from the sea cucumber Holothuria glaberrima [Díaz-Miranda et al. (1992) Biol. Bull. 182:241-247] represent the first neuropeptides isolated from holothurians. Using an antibody against GFSKLYFa, we describe here the localization and distribution pattern of GFSKLYFa-like immunoreactivity in H. glaberrima, where immunoreactive fibers form a prominent and extensive peptidergic nervous system component. Neuron-like cells and nerve fibers expressing GFSKLYFa-like immunoreactivity are found in the ectoneural and hyponeural divisions of the radial nerve cords as well as in the digestive, haemal, respiratory, and reproductive systems; in the tentacles; and in tube feet. Neuroendocrine-like cells are found in the mucosal layer of the intestine. Ultrastructure immunocytochemical analysis revealed that, in nerve cells and fibers in the serosal layer of the intestine, the immunoreactivity is concentrated in vesicles. The immunoreactive nerve fibers are found mainly within a dense nerve plexus overlying and in close contact with smooth muscle cells of the intestine. The exclusive expression of GFSKLYFa-like immunoreactivity in neuronal or neuroendocrine tissue together with the close apposition of some fibers to muscle cells suggests that GFSKLYFa acts as a neuromuscular transmitter or neuromodulator in H. glaberrima. The wide occurrence of GFSKLYFa-like immunoreactivity throughout the nervous system of the sea cucumber suggests that GFSKLYFa plays an important role in the control of multiple action systems, including digestion, respiration, circulation, reproduction, and locomotion.

    Objective(s): Marine organisms are known as a potential source of natural products, which contain bioactive substances with therapeutic properties. Sea cucumbers are prominent among marine organisms because of their dietary and therapeutic applications. In addition, they have capacity of synthesizing saponins molecules and other metabolites with therapeutic properties such as antitumor, antimicrobial, anti-inflammatory and antioxidant activities. The aim of this study was to evaluate the antioxidant and pro-apoptotic effects of sea cucumber saponins (SCS) isolated from Holothuria leucospilota species. Materials and Methods: Evaluation of antioxidant activity of SCS was carried out by DPPH (1, 1-diphenyl-2-picrylhydrazyl), ABTS (azino-bis-3-ethylbenzothiazoline-6-sulfonic acid), power reducing and total antioxidant assays. The anti-proliferative effect was studied by MTT (3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide) assay. Mechanisms leading to apoptosis were also evaluated by fluorescence microscopy, flow cytometry and real time PCR. Results: The results showed that the DPPH and ABTS activities increased in a dose dependent manner. The reducing capacity enhanced with increasing concentration of the saponin extract (0 to 2 mg/ml). The SCS exhibited moderate total antioxidant activity. Evaluation of anti-proliferative effect revealed that SCS with IC50 of about 6 ?g/ml, can display a good cytotoxic activity in a dose dependent manner. Further apoptosis induction was confirmed by fluorescence microscopy and flow cytometry. Sea cucumber saponin was also found to exert a pro-apoptotic effect by increasing the expression of Bax and decreasing the expression of Bcl2. Conclusion: These results indicate that the SCS may act as a natural antioxidant and antitumor agent. PMID:25810893

    The echinoderm nervous system is one of the least studied among invertebrates, partly because the tools available to study the neurobiology of this phylum are limited. We have now produced a monoclonal antibody (RN1) that labels a nervous system component of the sea cucumber Holothuria glaberrima. Western blots show that our antibody recognizes a major band of 66 kDa and a minor band of 53 kDa. Immunohistological experiments show that, in H. glaberrima, the antibody distinctly labels most of the known nervous system structures and some components that were previously unknown or little studied. A surprising finding was the labeling of nervous plexi within the connective tissue compartments of all organs studied. Double labeling with holothurian neuropeptides and an echinoderm synaptotagmin showed that RN1 labeled most, if not all, of the fibers labeled by these neuronal markers, but also a larger component of cells and fibers. The presence of a distinct connective tissue plexus in holothurians is highly significant since these organisms possess mutable connective tissues that change viscosity under the control of the nervous system. Therefore, the cells and fibers recognized by our monoclonal antibodies may be involved in controlling tensility changes in echinoderm connective tissue. PMID:17679718

    Members of the calbindin subfamily serve as markers of subpopulations of neurons within the vertebrate nervous system. Although markers of these proteins are widely available and used, their application to invertebrate nervous systems has been very limited. In this study we investigated the presence and distribution of members of the calbindin subfamily in the sea cucumber Holothuria glaberrima (Selenka, 1867). Immunohistological experiments with antibodies made against rat calbindin 1, parvalbumin, and calbindin 2, showed that these antibodies labeled cells and fibers within the nervous system of H. glaberrima. Most of the cells and fibers were co-labeled with the neural-specific marker RN1, showing their neural specificity. These were distributed throughout all of the nervous structures, including the connective tissue plexi of the body wall and podia. Bioinformatics analyses of the possible antigen recognized by these markers showed that a calbindin 2-like protein present in the sea urchin Strongylocentrotus purpuratus, corresponded to the calbindin-D32k previously identified in other invertebrates. Western blots with anti-calbindin 1 and anti-parvalbumin showed that these markers recognized an antigen of approximately 32 kDa in homogenates of radial nerve cords of H. glaberrima and Lytechinus variegatus. Furthermore, immunoreactivity with anti-calbindin 1 and anti-parvalbumin was obtained to a fragment of calbindin-D32k of H. glaberrima. Our findings suggest that calbindin-D32k is present in invertebrates and its sequence is more similar to the vertebrate calbindin 2 than to calbindin 1. Thus, characterization of calbindin-D32k in echinoderms provides an important view of the evolution of this protein family and represents a valuable marker to study the nervous system of invertebrates.

  13. Gillray Collection

    NSDL National Science Digital Library

    Gillray, James, 1756-1815

    Throughout history, illustrators and others have seen fit to accurately skewer politicians, religious leaders, and countless others through their creative drawings and words. Born in 1756, English illustrator James Gillray was part of this honorable tradition. He reigned supreme during a period that became known as the "golden age of English caricature," and he "chronicled and ridiculed the politicians and ruling class of his day." This collection of his work comes courtesy of Dickson Q. Brown (Princeton class of 1895) who donated 313 prints to the Princeton University Library. Visitors to the site won't want to miss his "A bouquet of the last century" or his highly effective "A peep into the cave of Jacobinism." Overall, it's a delightful set of images, and one that effectively demonstrates the power of such pieces of art and political commentary.

    1995-11-01

    1. Three species of sea cucumbers found in the Sabah coastal areas were screened for the presence of antibacterial activity using three methods of extraction. Tests were conducted in vitro using the agar absorption method. 2. Both the lipid extract and the methanol-solvent extract from Holothuria atra, Holothuria scabra and Bohadshia argus were found to show no antibacterial activity. 3. Phosphate-buffered saline (PBS) from H. atra and B. argus, however, inhibited the growth of all gram-positive and gram-negative bacteria. 4. Comparisons were also made between extracts from the outer layer of H. atra and its inner part, and it was found that the extract from the outer layer showed less bacterial growth inhibition property. 5. The bacterial growth inhibition property of the PBS extract from H. atra, however, is dependent on the extract's concentration. Bacterial growth inhibition was apparent after 48 hr incubation.

  9. Value, market preferences and trade of Beche-de-mer from Pacific Island sea cucumbers.

    PubMed

    Purcell, Steven W

    2014-01-01

    Market preferences of natural resources contribute to shape their exploitation and production. Beche-de-mer, the product after gutting, cooking, salting and drying sea cucumbers, is exported worldwide to Asian dried seafood markets. A better understanding of the trade, value and market preferences of Pacific island beche-de-mer could identify critical postharvest processing techniques and management strategies for fisheries and aquaculture. Data were collected on export prices and trade of beche-de-mer from Kiribati, Fiji, Tonga and New Caledonia, and the selling prices, respective sizes and organoleptic properties of the products in stores in China. Export prices varied considerably within and among the four countries and low-value species were the most exported by volume. Most of the beche-de-mer from the four Pacific islands is exported to Hong Kong, where quality products are sold and others are distributed to mainland China. Prices of the beche-de-mer in Chinese stores varied up to ten-fold and were mostly influenced by species, body size and, to a lesser extent, physical damage to the products. Market prices across species (averaging US$15-385 kg-1) appear to have mostly increased six- to twelve-fold over the past decade. The data allude that fisheries for Holothuria scabra, H. lessoni, H. fuscogilva, H. whitmaei and Thelenota ananas should be most carefully managed because they were the highest-value species and under greatest demand. The relationships between size of beche-de-mer and sale price were species specific and highly varied. This study also highlights the need for better regulations and/or enforcement of minimum size limits in sea cucumber fisheries, which can help to maximise economic benefits of wild stocks.

    Garbage collection can be done in vector mode on supercomputers like the Cray-2 and the Cyber 205. Both copying collection and mark-and-sweep can be expressed as breadth-first searches in which the queue can be processed in parallel. The authors have designed a copying garbage collector whose inner loop works entirely in vector mode. The only significant limitation of the algorithm is that if the size of the records is not constant, the implementation becomes much more complicated. The authors give performance measurements of the algorithm as implemented for Lisp CONS cells on the Cyber 205. Vector-mode garbage collection performs up to 9 times faster than scalar-mode collection.

Browsing the collection works better than searching, because it's a bit difficult to predict what terms will result in a successful search in a collection as varied as this. The books have been scanned carefully, so that it is possible to not only read every page but also to see the style of the covers and binding details. For example, "Book" by Brian Borchardt, consists of a series of short quotes related to books, including the well-known Jorge Luis Borges, "I have always imagined that paradise will be a kind of library."

  20. A Survey of Collectives

    NASA Technical Reports Server (NTRS)

    Tumer, Kagan; Wolpert, David

    2004-01-01

    Due to the increasing sophistication and miniaturization of computational components, complex, distributed systems of interacting agents are becoming ubiquitous. Such systems, where each agent aims to optimize its own performance, but where there is a well-defined set of system-level performance criteria, are called collectives. The fundamental problem in analyzing/designing such systems is in determining how the combined actions of self-interested agents leads to 'coordinated' behavior on a iarge scale. Examples of artificial systems which exhibit such behavior include packet routing across a data network, control of an array of communication satellites, coordination of multiple deployables, and dynamic job scheduling across a distributed computer grid. Examples of natural systems include ecosystems, economies, and the organelles within a living cell. No current scientific discipline provides a thorough understanding of the relation between the structure of collectives and how well they meet their overall performance criteria. Although still very young, research on collectives has resulted in successes both in understanding and designing such systems. It is eqected that as it matures and draws upon other disciplines related to collectives, this field will greatly expand the range of computationally addressable tasks. Moreover, in addition to drawing on them, such a fully developed field of collective intelligence may provide insight into already established scientific fields, such as mechanism design, economics, game theory, and population biology. This chapter provides a survey to the emerging science of collectives.

  1. Spectral imagery collection experiment

    NASA Astrophysics Data System (ADS)

    Romano, Joao M.; Rosario, Dalton; Farley, Vincent; Sohr, Brian

    2010-04-01

    The Spectral and Polarimetric Imagery Collection Experiment (SPICE) is a collaborative effort between the US Army ARDEC and ARL for the collection of mid-wave and long-wave infrared imagery using hyperspectral, polarimetric, and broadband sensors. The objective of the program is to collect a comprehensive database of the different modalities over the course of 1 to 2 years to capture sensor performance over a wide variety of adverse weather conditions, diurnal, and seasonal changes inherent to Picatinny's northern New Jersey location. Using the Precision Armament Laboratory (PAL) tower at Picatinny Arsenal, the sensors will autonomously collect the desired data around the clock at different ranges where surrogate 2S3 Self-Propelled Howitzer targets are positioned at different viewing perspectives at 549 and 1280m from the sensor location. The collected database will allow for: 1) Understand of signature variability under the different weather conditions; 2) Development of robust algorithms; 3) Development of new sensors; 4) Evaluation of hyperspectral and polarimetric technologies; and 5) Evaluation of fusing the different sensor modalities. In this paper, we will present the SPICE data collection objectives, the ongoing effort, the sensors that are currently deployed, and how this work will assist researches on the development and evaluation of sensors, algorithms, and fusion applications.

  2. Theory of Collective Intelligence

    NASA Technical Reports Server (NTRS)

    Wolpert, David H.

    2003-01-01

    In this chapter an analysis of the behavior of an arbitrary (perhaps massive) collective of computational processes in terms of an associated "world" utility function is presented We concentrate on the situation where each process in the collective can be viewed as though it were striving to maximize its own private utility function. For such situations the central design issue is how to initialize/update the collective's structure, and in particular the private utility functions, so as to induce the overall collective to behave in a way that has large values of the world utility. Traditional "team game" approaches to this problem simply set each private utility function equal to the world utility function. The "Collective Intelligence" (COIN) framework is a semi-formal set of heuristics that recently have been used to construct private utility. functions that in many experiments have resulted in world utility values up to orders of magnitude superior to that ensuing from use of the team game utility. In this paper we introduce a formal mathematics for analyzing and designing collectives. We also use this mathematics to suggest new private utilities that should outperform the COIN heuristics in certain kinds of domains. In accompanying work we use that mathematics to explain previous experimental results concerning the superiority of COIN heuristics. In that accompanying work we also use the mathematics to make numerical predictions, some of which we then test. In this way these two papers establish the study of collectives as a proper science, involving theory, explanation of old experiments, prediction concerning new experiments, and engineering insights.

The objective of the program is to collect a comprehensive database of the different modalities over the course of 1 to 2 years to capture sensor performance over a wide variety of weather conditions, diurnal, and seasonal changes inherent to Picatinny's northern New Jersey location. Using the Precision Armament Laboratory (PAL) tower at Picatinny Arsenal, the sensors will autonomously collect the desired data around the clock at different ranges where surrogate 2S3 Self-Propelled Howitzer targets are positioned at different viewing perspectives in an open field. The database will allow for: 1) Understanding of signature variability under adverse weather conditions; 2) Development of robust algorithms; 3) Development of new sensors; 4) Evaluation of polarimetric technology; and 5) Evaluation of fusing the different sensor modalities. In this paper, we will present the SPICE data collection objectives, the ongoing effort, the sensors that are currently deployed, and how this work will assist researches on the development and evaluation of sensors, algorithms, and fusion applications.

  5. Extension Project Collection

    NSDL National Science Digital Library

    The legacy of the Works Progress Administration (WPA) is evident in the thousands of various public projects they completed across the United States during the 1930s and 1940s. Across the country they employed thousands of persons, working on projects such as staging plays and crafting murals in public schools. One of their lesser known projects was the "Museum Extension Project", which was administered at the state level. The project produced hundreds of architectural models, dioramas, figurines, and other objects, designed for use in a host of educational settings. Fortunately enough, the Broward County Library in Fort Lauderdale, Florida has preserved over 700 of these visual aids, and placed them online in this digital collection. Visitors can read a fine introductory essay by librarian Jim Findlay about the WPA and the Museum Extension Project, then proceed to search the collection at their leisure. Overall, this is a rather fine collection and one that is well presented.

    The University of Geneva brain collection was founded at the beginning of the 20th century. Today, it consists of 10,154 formaldehyde- or buffered formaldehyde–fixed brains obtained from the autopsies of the Department of Psychiatry and, since 1971, from the Department of Geriatrics as well. More than 100,000 paraffin-embedded blocks and 200,000 histological slides have also been collected since 1901. From the time of its creation, this collection has served as an important resource for pathological studies and clinicopathological correlations, primarily in the field of dementing illnesses and brain aging research. These materials have permitted a number of original neuropathological observations, such as the classification of Pick’s disease by Constantinidis, or the description of dyshoric angiopathy and laminar sclerosis by Morel. The large number of cases, including some very rare conditions, provides a unique resource and an opportunity for worldwide collaborations. PMID:21599692

  19. Collective network routing

    DOEpatents

    Hoenicke, Dirk

    2014-12-02

    Disclosed are a unified method and apparatus to classify, route, and process injected data packets into a network so as to belong to a plurality of logical networks, each implementing a specific flow of data on top of a common physical network. The method allows to locally identify collectives of packets for local processing, such as the computation of the sum, difference, maximum, minimum, or other logical operations among the identified packet collective. Packets are injected together with a class-attribute and an opcode attribute. Network routers, employing the described method, use the packet attributes to look-up the class-specific route information from a local route table, which contains the local incoming and outgoing directions as part of the specifically implemented global data flow of the particular virtual network.

People can get their word out by posting to a blog, by editing a wiki or a web site, or even by using cost-effective print-on-demand book production services. In other words, collection development librarians now live in a world of hurt. All these methods, as well as a number of…

  6. Calvin Photographic Collection

    NSDL National Science Digital Library

    Provided by the University of Iowa, this site is another fine example of how the Internet allows worldwide access to unique collections that might otherwise go unnoticed. Samuel Calvin, Professor of Natural Sciences at the University of Iowa (1873-1911) and State Geologist, along with his colleagues, produced some 10,000 gelatin dry plates and glass plate negatives between 1880s and the 1920s. These photos documented Iowa's geological landscapes and features, along with mines, quarries, classes in the field, and their families. In addition to his training as a geologist, Calvin was also quite the photographer, as the large number of skillful and attractive images in this collection attest. These photos may be accessed in three ways: a slideshow of selected images, a topically organized scrapbook, or via a database. The database is browseable by Iowa county or state/ province (for those of Calvin's images taken outside of Iowa). The photos are presented as large thumbnails which link to full-sized images. The site also offers general information on the collection and a very brief biographical sketch of Calvin.

  7. Alfred Russel Wallace Collection

    NSDL National Science Digital Library

    One name looms large for the general public when the word "evolution" is mentioned: Charles Darwin. Of course, others are quite aware that Alfred Russel Wallace co-discovered the theory of evolution with Darwin, a fact that the prescient individuals at the Natural History Museum in Britain are well aware of. In 2002, the Museum was able to purchase a rather large collection of Wallace's personal and related family papers, correspondence, photographs, and other items from the Wallace family. With the generous support of the Mellon Foundation, the Museum has digitized approximately 200 items from this collection and placed them online at this site. Visitors may wish to start by looking over a brief biography of Wallace, and then taking a look at the detailed chronology of the main events in his life. The "Online Collection" section is where the heart of the material lies, as visitors can view Wallace's original notes on evolution, read about his encounters with spiritualism, and a number of touching letters that include a note on Wallace's troubles with his cats, Crumpet and Flunkie.

  8. Portable liquid collection electrostatic precipitator

    SciTech Connect

    Carlson, Duane C.; DeGange, John J.; Halverson, Justin E.

    2005-10-18

    A portable liquid collection electrostatic collection precipitator for analyzing air is provided which is a relatively small, self-contained device. The device has a tubular collection electrode, a reservoir for a liquid, and a pump. The pump pumps the liquid into the collection electrode such that the liquid flows down the exterior of the collection electrode and is recirculated to the reservoir. An air intake is provided such that air to be analyzed flows through an ionization section to ionize analytes in the air, and then flows near the collection electrode where ionized analytes are collected. A portable power source is connected to the air intake and the collection electrode. Ionizable constituents in the air are ionized, attracted to the collection electrode, and precipitated in the liquid. The precipitator may also have an analyzer for the liquid and may have a transceiver allowing remote operation and data collection.

  9. Collective Intelligence. Chapter 17

    NASA Technical Reports Server (NTRS)

    Wolpert, David H.

    2003-01-01

    Many systems of self-interested agents have an associated performance criterion that rates the dynamic behavior of the overall system. This chapter presents an introduction to the science of such systems. Formally, collectives are defined as any system having the following two characteristics: First, the system must contain one or more agents each of which we view as trying to maximize an associated private utility; second, the system must have an associated world utility function that rates the possible behaviors of that overall system. In practice, collectives are often very large, distributed, and support little, if any, centralized communication and control, although those characteristics are not part of their formal definition. A naturally occurring example of a collective is a human economy. One can identify the agents and their private utilities as the human individuals in the economy and the associated personal rewards they are each trying to maximize. One could then identify the world utility as the time average of the gross domestic product. ("World utility" per se is not a construction internal to a human economy, but rather something defined from the outside.) To achieve high world utility it is necessary to avoid having the agents work at cross-purposes lest phenomena like liquidity traps or the Tragedy of the Commons (TOC) occur, in which agents' individually pursuing their private utilities lowers world utility. The obvious way to avoid such phenomena is by modifying the agents utility functions to be "aligned" with the world utility. This can be done via punitive legislation. A real-world example of an attempt to do this was the creation of antitrust regulations designed to prevent monopolistic practices.

    In 1946, Lauren R. Donaldson and several of his scientific colleagues were selected as radiation monitors for Operation Crossroads, which was the codename for the first atomic bomb tests at Bikini Atoll. During this operation, two nuclear bombs were detonated above and below the ocean surface, contaminating the organs and tissues of living creatures and plants with large doses of radioactivity. Over the next twelve years, Dr. Donaldson and his colleagues would return a number of times to perform research related to these activities. Recently, the University of Washington Libraries Digital Collections team digitized selected personal logs, photo albums, papers, and ephemera from the surveys undertaken by this team of researchers. Visitors can browse the collection, or they may wish to get started by looking over the sample searches which include "1946 Operation Crossroads" and "1947 Bikini Atoll Radiological Survey". Also, visitors can learn more about Dr. Donaldson and peruse a finding aid for his own personal and academic papers which are also held by the University of Washington.

  17. The George Raper Collection

    NSDL National Science Digital Library

    This new online exhibit highlights the National Library of Australia's latest acquisition, the personal papers of George Raper, who sailed in 1787 at age seventeen from England to Australia as Able Seaman (later Midshipman) on the HMS Sirius, the flagship of the First Fleet. In addition to participating in one of the earliest European settlements of Australia, Raper circumnavigated the globe, narrowly escaped shipwreck twice, spent eleven months on Norfolk Island after the Sirius foundered on a reef in 1790, and finally returned home, where he and the other officers had to face a court-martial for losing the ship (all were exonerated) before being reunited with his family. Held by the Raper family for over 200 years, the National Library has recently acquired Raper's naval observations as well as a collection of maps and coastal drawings he made during this trip. These have been digitized and placed on display at this fine site. Some of these materials are included in the compelling story of the Sirius in the Biography section. They can also be viewed in the Collection section, where the maps, coastal profiles, and Raper's painting of the wreck are offered as thumbnails with commentary. Users with the MrSID Online Viewer plug-in (link to free download provided) can view the images in varying sizes and resolutions. Raper's navigation calculations may be downloaded in MS Word format. An interactive timeline is also provided.

    2012-03-16

    The good folks at the Dartmouth Digital Library Initiatives continue to offer a veritable cornucopia of printed ephemera, and this website will delight anyone with an interest in topics as wide-ranging as comics, Dr. Seuss, Russian placards, or the Arctic. Here visitors can make their way through nine digitized works, including "The Fortunes of Ferdinand Flipper." This particular item was published in the 1850s, and is widely considered to be the first comic book written in the United States. The collection here also includes Theodor Geisel's (Dr. Seuss) reflections on his early career as a young artist up to the publication of his 1937 book "And to Think That I Saw It on Mulberry Street." Further along, visitors will find a collection of Russian placards dating from 1917 to 1922 designed by one V. Lebedev for the state news agency of Soviet Russia. Finally, the site also includes 16 volumes of the magisterial Encyclopedia Arctica, which was sponsored by the U.S. Office of Naval Research. The work was never formally published, and it documents hundreds of scientific, zoological, and geographic topics.

Visitors can look through the materials via the Author List or use the Title heading to look around. Documents on the site include a wealth of treaties regarding fishing practices and limitations along with documents detailing the particulars of different religious ceremonies. The site is rounded out by the inclusion of a comprehensive search engine.

  4. Milman Parry Collection

    NSDL National Science Digital Library

    Part musicologist, part just plain curious, Milman Parry embarked on a quest to document and record the musical traditions of South Slavic song in the 1930s. Along the way, he came up with a provocative thesis: The epic tradition of storytelling and narrative present in the Iliad and Odyssey were not originally literary in nature, but rather part of the tradition of an archaic Greek oral tradition. After he passed away in 1935, his rather impressive collection found its way to Harvard University. Over the past few years, the staff at the Widener Library at Harvard have worked to place many of his field recordings and notes online, and their work has culminated in this fine website. Visitors to the site will want to listen to a few of these songs, and then perhaps also read some of the essays that explain the importance of his work, and that of his colleague, Albert B. Lord.

    1979-01-01

    A fixed, linear, ground-based primary reflector having an extended curved sawtooth-contoured surface covered with a metalized polymeric reflecting material, reflects solar energy to a movably supported collector that is kept at the concentrated line focus reflector primary. The primary reflector may be constructed by a process utilizing well known freeway paving machinery. The solar energy absorber is preferably a fluid transporting pipe. Efficient utilization leading to high temperatures from the reflected solar energy is obtained by cylindrical shaped secondary reflectors that direct off-angle energy to the absorber pipe. A seriatim arrangement of cylindrical secondary reflector stages and spot-forming reflector stages produces a high temperature solar energy collection system of greater efficiency.

This remarkable digital collection from the Boston Public Library contains 46 scrapbooks that document his fascinating journeys. First-time visitors might do well to check out "Volume 31: On the Nile. Cairo to Luxor" as a good starting point. Here they will find photographs of local attractions and curiosities purchased during Tupper's travels. There are shots of markets, local businesspeople, the pyramids, and festivals. There are many other volumes here, of course, and visitors will be delighted to know that each one contains at least 35 photos for their consideration. It's a remarkable find and for persons interested in the history of travel and journeys, it's a site to bookmark and visit again.

  8. Prokudin-Gorskii Collection

    NSDL National Science Digital Library

    Born in the town of Murom, Russia, Sergei Mikhailovich Prokudin-Gorskii was educated as a chemist and dedicated his life to the advancement of photography. He spent many years documenting the Russian Empire, and he was even outfitted with a railroad car-darkroom provided by Tsar Nicholas II. Along with this equipment, the Tsar also gave him access to certain restricted areas. After Prokudin-Gorskii died in 1944, his sons sold his collection of photographs, glass negatives, and sepia-tone prints to the Library of Congress in 1948. This site allows visitors to view these images, which include photographs of prominent religious structures, public works, industrial areas, and people in traditional dress. Visitors can also look over some of the thematic albums, which include his travels to Central Asia in 1911 and his journey along the Oka River south of Moscow in 1912.

  9. Costume History Collection

    NSDL National Science Digital Library

    Four books make up the rather elegant digital Costume History Collection at the Western Michigan University Library, and to pore through their pages is to experience the world of 18th and 19th century fashion. The books include designs from a Parisian women's magazine, color drawings of clothing of people of Persia, and a series of pattern diagrams. The Persian items are taken from the rather intriguing 1843 work, "A Residence of Eight Years in Persia, Among the Nestorian Christians: with Notices of the Muhammedans." The other three books offered here in their entirety include "L'Art de la Lingere" and "Parisian Fashion, 1827-1832". This last volume is also supplemented by a glossary and annotated bibliography. Moving on, the site also includes a section on the digitization particulars of this project.

  10. Internet Archive: Movie Collection

    NSDL National Science Digital Library

    In addition to its Wayback Machine (last mentioned in the November 2, 2001 Scout Report, the Internet Archive offers the Internet Moving Images Archive, an extensive collection of digitized films from the Prelinger Archives. Not Hollywood movies, these films should provide researchers and scholars unique insight into certain aspects of 20th-century culture, industry, and institutions. Being able to select from titles like Care of Hair and Nails (1951), The Kingdom of Plastics (1955), and This is Coffee (1961), other users should easily find something interesting in the 956-film archive. Each film tends to have multiple file formats; RealPlayer, MPEG-2, and MPEG-4 are the most frequently employed. Because many of the files are over 100MB, users with low bandwidth should be wary.

  11. The Margo Duggan Collection

    NSDL National Science Digital Library

    Margo Duggan served in the United States Marine Corps during World War II, and after the war was over she started working as a civilian employee of the United States Trust Territories Administration in 1949. Over the next five years, she worked on a number of the Marshall, Mariana, and Caroline Islands and over at the Trust Territory headquarters in Hawai'i. She took a number of photographs during her time, and they document an important moment in the history of Micronesia. The University of Hawaii at Manoa's Library created this site, and visitors can view over 1,000 of the images she created. Curious visitors can read a brief biography of Duggan here and also look over the "About" page to learn more how the collection came to the university. The majority of the images here document life in Micronesia, and visitors can look through them via title, category, date, location, or reference number.

  18. Sea cucumber aquaculture in the Western Indian ocean: challenges for sustainable livelihood and stock improvement.

    PubMed

    Eriksson, Hampus; Robinson, Georgina; Slater, Matthew J; Troell, Max

    2012-03-01

    The decline in sea cucumber fisheries that serve the Asian dried seafood market has prompted an increase in global sea cucumber aquaculture. The tropical sandfish (Holothuria scabra) has, in this context, been reared and produced with mixed success. In the Western Indian Ocean, villagers often participate in the export fishery for sea cucumbers as a source of income. However, with a growing concern of depleted stocks introduction of hatcheries to farm sandfish as a community livelihood and to replenish wild stocks is being promoted. This review identifies and discusses a number of aspects that constitute constraints or implications with regard to development of sandfish farming in the region. The conclusion is that for sandfish farming to live up to its expectations the possible impacts need to be further studied, and that improved evaluation of ongoing projects is required. In the interim, a precautionary approach toward new enterprise activities is suggested. PMID:22083524

  1. The Florida Folklife Collection

    NSDL National Science Digital Library

    With generous funding from the Institute of Museum and Library Services, the Florida State Archives has recently finished an ambitious two-year project to enhance access to a number of items in the Florida Folklife Collection by creating The Florida Memory Project website. No doubt the site will be of great interest to folklorists and the general public, as it contains an online index with descriptions of 50,000 photographic images and close to 5,000 audio recordings. Additionally, visitors can peruse over 10,000 of these photographic images by performing detailed searches. Visitors can also look through the audio section for a number of real finds, including a WPA recording of a work song performed by Zora Neale Hurston along with other folk song recordings. The site also includes five separate educational units, which may be used in the classroom, or perused at the discretion of each visitor. The units include discussions of the history of net making and net fishing in Florida and the creation of Seminole dolls by noted doll maker Mary B. Billie.

  2. Surmounting collectively oscillating bottlenecks

    E-print Network

    D. Hennig; L. Schimansky-Geier; P. Hänggi

    2008-07-29

    We study the collective escape dynamics of a chain of coupled, weakly damped nonlinear oscillators from a metastable state over a barrier when driven by a thermal heat bath in combination with a weak, globally acting periodic perturbation. Optimal parameter choices are identified that lead to a drastic enhancement of escape rates as compared to a pure noise-assisted situation. We elucidate the speed-up of escape in the driven Langevin dynamics by showing that the time-periodic external field in combination with the thermal fluctuations triggers an instability mechanism of the stationary homogeneous lattice state of the system. Perturbations of the latter provided by incoherent thermal fluctuations grow because of a parametric resonance, leading to the formation of spatially localized modes (LMs). Remarkably, the LMs persist in spite of continuously impacting thermal noise. The average escape time assumes a distinct minimum by either tuning the coupling strength and/or the driving frequency. This weak ac-driven assisted escape in turn implies a giant speed of the activation rate of such thermally driven coupled nonlinear oscillator chains.

  3. Lehman Brothers Collection

    NSDL National Science Digital Library

    In the late 1840s, Henry Lehman made the journey from Germany to Alabama, where he established a dry goods store. Several years later, he was joined by his two brothers and over the coming years the firm of Lehman Brothers would become a commodities broker buying and selling cotton for the planters in the area. They opened a New York office in 1858, and during the next century and a half they would become one of the world's most prominent financial firms. Lehman Brothers collapsed in 2008, but curious persons can still learn about their various dealings via this site. The Lehman Brothers Collection at Harvard University's Baker Library contains digitized records of their deal books from the 1920s to the 1980s. On the homepage, visitors can learn about the history of the firm, and also use the "Using the Deal Books" to learn how to decipher all of their transactions. The deal books can also be browsed by chronology, company, or industry. That's far from all, as the site also has extensive business records, which include executive records, financial documents, and correspondence. Taken as a whole, it's a tremendous resource for persons with an interest in business history and American history more generally.

  4. The Jane Johnson Collection

    NSDL National Science Digital Library

    Back in the middle of the 18th century, what was a young parent to do when it came to providing a meaningful and lasting education for their son or daughter? It would be a few decades before Rousseau's Emilie, and a bit longer for John Dewey to make the scene, so parents had to be a bit more creative. One particularly enterprising soul was Jane Johnson, who decided to create a set of materials designed to instruct her son, George William Johnson, in a variety of subjects. Several hundred years later, the good folks at Indiana University's Lilly Library decided to digitize these rather remarkable teaching aids so that the web-browsing public might be able to look through them at their leisure. All told, there are 438 separate pieces, including six sets of alphabet cards (complete with vowel sounds), two booklets, three sets of lesson cards in verse and anecdotal form, and several card sets of moral instruction. The cards are quite visually appealing, and they contain references to such contemporaries as George Berkeley, and George Wright, a noted Member of Parliament. For those with a penchant for taking a stroll down the memory lane of pedagogy and instruction, this collection is worth several visits.

  5. American Collection: Educator's Site

    NSDL National Science Digital Library

    This unusually rich companion Website has been posted in advance of the broadcast of the series, American Collection, a PBS special event presenting nine films based on the works of major American authors, including Willa Cather, Eudora Welty, Langston Hughes, and Henry James. The heart of the site offers "teaching resources, lesson plans, background information, author profiles, online links, and behind-the-scenes production news on the films that will be seen on the series and the works of American literature on which they are based." The site also features a "gateway" of educator-selected sites on (currently) over 50 prominent writers in American literature; a video-finder for American literature on videotape (including films); and a "literary map" that is under construction, allowing high school students to participate by producing informative essays on writers from their region for posting on-site. A separate section also gives students the opportunity to post projects, games, and puzzles relating to the study and appreciation of American literature. Note: Material on the other five films will be added over the coming months. The series itself will begin broadcasting in 2000 on PBS and is a joint venture of PBS, Masterpiece Theatre, and the National Council of Teachers of English (NCTE).

  8. Physician collective bargaining.

    PubMed

    Schiff, Anthony Hunter

    2009-11-01

    Current antitrust enforcement policy unduly restricts physician collaboration, especially among small physician practices. Among other matters, current enforcement policy has hindered the ability of physicians to implement efficient healthcare delivery innovations, such as the acquisition and implementation of health information technology (HIT). Furthermore, the Federal Trade Commission and Department of Justice have unevenly enforced the antitrust laws, thereby fostering an increasingly severe imbalance in the healthcare market in which dominant health insurers enjoy the benefit of largely unfettered consolidation at the cost of both consumers and providers. This article traces the history of antitrust enforcement in healthcare, describe the current marketplace, and suggest the problems that must be addressed to restore balance to the healthcare market and help to ensure an innovative and efficient healthcare system capable of meeting the demands of the 21st century. Specifically, the writer explains how innovative physician collaborations have been improperly stifled by the policies of the federal antitrust enforcement agencies, and recommend that these policies be relaxed to permit physicians more latitude to bargain collectively with health insurers in conjunction with procompetitive clinical integration efforts. The article also explains how the unbridled consolidation of the health insurance industry has resulted in higher premiums to consumers and lower compensation to physicians, and recommends that further consolidation be prohibited. Finally, the writer discusses how health insurers with market power are improperly undermining the physician-patient relationship, and recommend federal antitrust enforcement agencies take appropriate steps to protect patients and their physicians from this anticompetitive conduct. The article also suggests such steps will require changes in three areas: (1) health insurers must be prohibited from engaging in anticompetitive activity; (2) the continuing improper consolidation of the health insurance industry must be curtailed; and (3) the physician community must be permitted to undertake the collaborative activity necessary for the establishment of a transparent, coordinated, and efficient delivery system.

  9. Collective Hamiltonian for wobbling modes

    E-print Network

    Q. B. Chen; S. Q. Zhang; P. W. Zhao; J. Meng

    2014-07-14

    The simple, longitudinal, and transverse wobblers are systematically studied within the framework of collective Hamiltonian, where the collective potential and mass parameter included are obtained based on the tilted axis cranking approach. Solving the collective Hamiltonian by diagonalization, the energies and the wave functions of the wobbling states are obtained. The obtained results are compared with those by harmonic approximation formula and particle rotor model. The wobbling energies calculated by the collective Hamiltonian are closer to the exact solutions by particle rotor model than harmonic approximation formula. It is confirmed that the wobbling frequency increases with the rotational frequency in simple and longitudinal wobbling motions while decreases in transverse wobbling motion. These variation trends are related to the stiffness of the collective potential in the collective Hamiltonian.

    Environmental restoration and waste management decisions rely on defensible environmental data. The major elements of the environmental data collection process lay out the steps to address what data need to be collected and how data are assessed for usability in decision making. These data collection process elements are planning, sampling, analysis, data verification and validation, and data quality assessment. This paper describes the elements, along with some of the tools currently used to implement them, and how the elements relate to each other.

  13. On the psychodynamics of collecting.

    PubMed

    Subkowski, Peter

    2006-04-01

    The urge to collect is a ubiquitous phenomenon which has anthropological, sociobiological and individual psychodynamic roots, but occurs far more frequently among men than women. The author examines the reasons for this gender difference and defines systematic collecting to distinguish it from addictive, obsessive and messy collecting, and from related phenomena such as perversion. The mode of collecting and choice of object are important indicators as to the unconscious psychodynamics of a collector and offer opportunity to describe his structural level. Collecting ranges across a broad spectrum, from an ego-syntonic integrated mode, i.e. sublimation, to a neurotic defence against pre-oedipal or oedipal traumas and conflicts. Alongside this drive-theoretical approach, object and Kleinian theory are also applied to the understanding of collecting. Collecting represents a specific form of object relating and way of handling primary loss trauma, which is different from addiction, compulsion, or perversion. Under certain circumstances collecting can also result in a successful Gestalt or way of life. The paper concludes with a case study showing how collecting develops from a pre-oedipal to a more integrated oedipal mode during the course of the analysis, which is reflected in changes in the transference.

    This system measures tritium on-line and collects tritium from a flowing inert gas stream. It separates the tritium from other non-hydrogen isotope contaminating gases, whether radioactive or not. The collecting portion of the system is constructed of various zirconium alloys called getters. These alloys adsorb tritium in any of its forms at one temperature and at a higher temperature release it as a gas. The system consists of four on-line getters and heaters, two ion chamber detectors, two collection getters, and two guard getters. When the incoming gas stream is valved through the on-line getters, 99.9% of it is adsorbed and the remainder continues to the guard getter where traces of tritium not collected earlier are adsorbed. The inert gas stream then exits the system to the decay chamber. Once the on-line getter has collected tritium for a predetermined time, it is valved off and the next on-line getter is valved on. Simultaneously, the first getter is heated and a pure helium purge is employed to carry the tritium from the getter. The tritium loaded gas stream is then routed through an ion chamber which measures the tritium activity. The ion chamber effluent passes through a collection getter that readsorbs the tritium and is removable from the system once it is loaded and is then replaced with a clean getter. Prior to removal of the collection getter, the system switches to a parallel collection getter. The effluent from the collection getter passes through a guard getter to remove traces of tritium prior to exiting the system. The tritium loaded collection getter, once removed, is analyzed by liquid scintillation techniques. The entire sequence is under computer control except for the removal and analysis of the collection getter. 7 figs.

  5. Library of Virginia: Photographic Collections

    NSDL National Science Digital Library

    The Library of Virginia's ongoing Digital Library Program in 2001 added eight public library digital photograph collections. Starting from the LVA Digital Library homepage, users select the name of one of the public library collections to go directly to its search page. For a little more information about the type of photographs to expect in each collection, we recommend beginning at the About the Collections page. Following this route, a user can learn that the digitized portion of the Hampton Public Library consists of 1,400 photographs from the Christopher E. Cheyne collection, including many downtown Hampton businesses, representing the seafood industry hotels and seaside resorts, and the amusement park. This collection also includes portraits of a few Civil War veterans, members of prominent Hampton families, and photographer Cheyne's family. In contrast, one would find fewer images of people in the Newport News Public Library collection, since it consists of close to 300 images related to the construction of Hilton Village, a World War I era public housing project, and the Hotel Warwick, a grand nineteenth-century resort. Searching is still a little unpredictable even with the additional information; to browse most of the images in a collection, try searching on a photographer's name, or the proper name of prominent subjects depicted.

  17. Schistosomiasis collection at NHM (SCAN)

    PubMed Central

    2012-01-01

    Background The Natural History Museum (NHM) is developing a repository for schistosomiasis-related material, the Schistosomiasis Collection at NHM (SCAN) as part of its existing Wolfson Wellcome Biomedical Laboratory (WWBL). This is timely because a major research and evaluation effort to understand control and move towards elimination of schistosomiasis in Africa has been initiated by the Schistosomiasis Consortium for Operational Research and Evaluation (SCORE), resulting in the collection of many important biological samples, including larval schistosomes and snails. SCAN will collaborate with a number of research groups and control teams and the repository will acquire samples relevant to both immediate and future research interest. The samples collected through ongoing research and field activities, WWBL’s existing collections, and other acquisitions will be maintained over the long term and made available to the global research community for approved research purposes. Goals include: · Consolidation of the existing NHM schistosome and snail collections and transfer of specimens into suitable long-term storage systems for DNA retrieval, · Long-term and stable storage of specimens collected as part of on going field programmes initially in Africa especially relating to the SCORE research programmes, · Provision of access to snail and schistosome collections for approved research activities.

    The installation of environmental data collection systems at several remotely located sites in islands in the Pacific Ocean is summarized. The effort was designed to enhance the ability to collect hydrological information. The data collection station consists of a data acquisition system for handling data, a transmitter for uplinking information to the GOES-W geostationary satellite, and a variety of environmental sensors for data accumulation. Each system was assembled, tested, and deployed on designated islands. The concept of using microprocessors for handling data at remote sites and relaying it via a satellite link is a cost effective approach. Such systems require high reliability and proven performance in the field.

    Rowe, D.J.; Rosensteel, G.

    1980-04-15

    A general procedure is given for decomposing N-particle configuration space into orbits of a kinematical collective group and a smooth transversal. EValuation of the Laplace-Beltrami operator, in terms of vector fields tangent to the orbit and to the transversal, gives the decomposition of the kinetic energy into collective and intrinsic parts. By such geometric means, the essence of the various transformations of coordinates is revealed in a simple coordinate free way. Specifically considered are the kinematical collective groups SO(3) and GL/sub +/(3,R). It is also shown that, with center-of-mass motion removed, N-particle configuration space can be considered as an orbit of the group GL/sub +/(3,R) x SO(N-1). This decomposition of the configuration space is observed to induce a corresponding decomposition of the N-particle Hilbert space into irreducible subspaces with respect to both interesting spectrum generating algebras for collective motion and of the symmetric group. Thus the connection is established with the algebraic approach to the microscopic realization of collective states, with full respect for the Pauli principle.

    Collective behaviour is a widespread phenomenon in biology, cutting through a huge span of scales, from cell colonies up to bird flocks and fish schools. The most prominent trait of collective behaviour is the emergence of global order: individuals synchronize their states, giving the stunning impression that the group behaves as one. In many biological systems, though, it is unclear whether global order is present. A paradigmatic case is that of insect swarms, whose erratic movements seem to suggest that group formation is a mere epiphenomenon of the independent interaction of each individual with an external landmark. In these cases, whether or not the group behaves truly collectively is debated. Here, we experimentally study swarms of midges in the field and measure how much the change of direction of one midge affects that of other individuals. We discover that, despite the lack of collective order, swarms display very strong correlations, totally incompatible with models of non-interacting particles. We find that correlation increases sharply with the swarm's density, indicating that the interaction between midges is based on a metric perception mechanism. By means of numerical simulations we demonstrate that such growing correlation is typical of a system close to an ordering transition. Our findings suggest that correlation, rather than order, is the true hallmark of collective behaviour in biological systems. PMID:25057853

  9. University of Nebraska Libraries Digital Collections: Government Comics Collection

    NSDL National Science Digital Library

    If titles such as "Adventures of the Garbage Gremlin" and "Adventures on Space Station Freedom" sound like comic book titles, it's because they are. These titles weren't produced by Marvel or DC however, but rather by the federal government. This digital collection of these works is the result of a two-year scanning and research project initiated by Richard Graham, assistant professor and digital media librarian at the University of Nebraska at Lincoln. All told, the collection contains 180 comics, posters, and transcripts from congressional hearings on comics. Visitors can search through the entire collection and they will also quickly get a sense of the pedagogical function of these rather curious documents. There are a few "classics" here, including the legendary "Bert The Turtle Says Duck And Cover", which was intended to provide instruction on what to do in case of a nuclear weapon attack.

  12. Electrostatic particle collection in vacuum

    NASA Astrophysics Data System (ADS)

    Afshar-Mohajer, Nima; Damit, Brian; Wu, Chang-Yu; Sorloaica-Hickman, Nicoleta

    2011-09-01

    Lunar grains accumulate charges due to solar-based ionizing radiations, and the repelling action of like-charged particles causes the levitation of lunar dust. The lunar dust deposit on sensitive and costly surfaces of investigative equipment is a serious concern in lunar explorations. Inspired by electrostatic precipitators (ESPs), the Electrostatic Lunar Dust Collector (ELDC) was proposed for collecting already charged lunar dust particles to prevent the lunar dust threat. As the conditions for terrestrial counterparts are not valid in the lunar environment, equations developed for terrestrial devices yield incorrect predictions in lunar application. Hence, a mathematical model was developed for the ELDC operating in vacuum to determine its collection efficiency. The ratios of electrical energy over potential energy, kinetic energy over potential energy and the ratio of ELDC dimensions were identified to be the key dimensionless parameters. Sensitivity analyses of the relevant parameters showed that depending on ELDC orientation, smaller particles would be collected more easily at vertical orientation, whereas larger particles were easier to collect in a horizontal ELDC configuration. In the worst case scenario, the electrostatic field needed to be 10 times stronger in the vertical mode in order to adequately collect larger particles. The collection efficiency was very sensitive to surface potential of lunar dust and it reached the maximum when surface potential was between 30 and 120 V. Except for regions of the lunar day side with surface potential close to zero, providing 1 kV ( E = 20 kV m -1) with the ELDC was more than enough for collecting all the particles in the most critical orientation. The needed field strength was about 4000 times less than that for repelling 1-?m size particles already settled on the surfaces. The analysis shows that the ELDC offers a viable solution for lunar dust control due to its effectiveness, ease of cleaning and low voltage requirements.

    The paper describes the way and results of human reliability data analysis collected as a part of the Bohunice Simulator Data Collection Project (BSDCP), which was performed by VUJE Trnava, Inc. with funding support from the U.S. DOE, National Nuclear Security Administration. The goal of the project was to create a methodology for simulator data collection and analysis to support activities in probabilistic safety assessment (PSA) and human reliability assessment for Jaslovske Bohunice nuclear power plant consisting of two sets of twin units: two VVER 440/V-230 (V1) and two VVER 440/V-213 (V2) reactors. During the project training of V-2 control room crews was performed at VUJE-Trnava simulator. The simulator training and the data collection were done in parallel. The main goal of BSDCP was to collect suitable data of human errors under simulated conditions requiring the use of symptom-based emergency operating procedures (SBEOPs). The subjects of the data collection were scenario progress time data, operator errors, and real-time technological parameters. The paper contains three main parts. The first part presents preparatory work and semi-automatic computer-based methods used to collect data and to check technological parameters in order to find hidden errors of operators, to be able to retrace the course of each scenario for purposes of further analysis, and to document the whole training process. The first part gives also an overview of collected data scope, human error taxonomy, and state classifications for SBEOP instructions coding. The second part describes analytical work undertaken to describe time distribution necessary for execution of various kinds of instructions performed by operators according to the classification for coding of SBEOP instructions. It also presents the methods used for determination of probability distribution for different operator errors. Results from the data evaluation are presented in the last part of the paper. An overview of observed human error probabilities (HEP) according to the developed taxonomy is given. HEP observed during training process were used as reference input data for HRA (Human Reliability Assesment) within existing PSAs performed by VUJE. Observing two different training seasons offered an opportunity to compare a progress achieved through the training process. This paper shows us how it is possible to make this kind of comparison in order to establish an objective measure of training quality and to determine training weaknesses. Results gained during the project-evoked interest of different NPPs (Nuclear Power Plant) in Slovak Republic to collect and process simulator data for further improvement of human factor safety, operational procedures, training process, etc. (authors)

The first problem was motivated after a result in the study of D3-branes in String Theory established a connection between a Del Pezzo surface of degree 1 and the finite trihedral group Delta27 through a three block exceptional collection. We prove after understanding these collections in depth that this connection can only be extrapolated to two other cases: P2 is connected to Z3 and the smooth cubic surfaces in P3 are connected to Z3? Z3 . The second problem was motivated as well by String Theory, and it consists of finding and describing the exceptional sheaves and collections on the singular reducible variety S=P2?H 3 where P2?H3 =P1 . The surface S became an object of study when a crepant resolution of the singularity of type ?(1, 1, 3) was found. More specifically, S is formed by the exceptional compact surfaces of the resolution. We provide insight in the study of the exceptionality of sheaves on S, finally showing that complete exceptional collections of invertible sheaves on S don't exist. We also show how to use mutations of exceptional pairs on S using the bounded derived category of sheaves Db(S).

  3. William J. Meuer Photoart Collection

    NSDL National Science Digital Library

    In some places, collegiate life and so-called "town-gown" activities and relationships are well-documented. The University of Wisconsin is just such a place, and recently the University of Wisconsin's Digital Collections group placed a cornucopia of photographic material online related to just this subject. The Meuer Photoart Collection draws on the work on local photographer William J. Meuer. Meuer and his brother, Roman, opened their photography business on Madison's State Street in 1916. Over a period that spanned forty years, Meuer took photographs of hundreds of faculty members at the University and documented lectures, social events, intramural and informal sporting events, and dramatic presentations. Currently, visitors can page through the first eight volumes of this twenty-five volume collection or they may also search the text of these albums for items of note.

  5. Fossil Collection and Museum Curation

    NSDL National Science Digital Library

    Diana Boyer

    Before we go into the field, students are exposed to field collection techniques and appropriate information to collect at the outcrop. This assignment is good for field trips because students each collect 1 or few samples, but spend time on the outcrop measuring a section and collecting associated lithologic and other fossil data if available (locality information, exposure, over and underlying sedimentology, details of host rock, sedimentary structures, assocaited fossils, diversity and abundance, taphonomic condition of fossils, etc). The field locality can be anywhere where there are resaonably well preserved fossils (and should give students an appreciation of museum quality specimens). This allows this exercise to be flexible as field trip localities change. All of the information that they collect in the field will be included in their field notebook that is handed in at the end of the field trip for evaluation. In the lab-I used class time-students are asked to make a detailed sketch of their sample that they can take to the library with them, and a discussion is held as to where to look for information to identify specimens with. Students are given a week (variable depending on the availability of resources, for example if monographs need to be aquired through inter-library loan) to idenitfy their specimen and then asked to catalog them for the museum. They fill out a SUNY Oswego Paleontology Museum card, which they have seen all semester for their sample and are given the option to donate it to the collection or keep it.

    We posit a new geometric perspective to define, detect, and classify inherent patterns of collective behaviour across a variety of animal species. We show that machine learning techniques, and specifically the isometric mapping algorithm, allow the identification and interpretation of different types of collective behaviour in five social animal species. These results offer a first glimpse at the transformative potential of machine learning for ethology, similar to its impact on robotics, where it enabled robots to recognize objects and navigate the environment.

    We consider systems of interacting reinforcement learning (RL) algorithms that do not work at cross purposes , in that their collective behavior maximizes a global utility function. We call such systems COllective INtelligences (COINs). We present the theory of designing COINs. Then we present experiments validating that theory in the context of two distributed control problems: We show that COINs perform near-optimally in a difficult variant of Arthur's bar problem [Arthur] (and in particular avoid the tragedy of the commons for that problem), and we also illustrate optimal performance in the master-slave problem.

  9. Gilmer Civil War Maps Collection

    NSDL National Science Digital Library

    During a long career in the United States and Confederate States of American Armies, Jeremy Francis Gilmer served as an engineer. Responsible for constructing fortifications and conducting land surveys, he created dozens of maps and other such documents. Eventually, these materials found their way to the University of North Carolina Library, and most recently a number of these materials were digitized. All told, this collection currently contains 161 maps, plans, and land surveys, spanning the region from Alabama to Virginia. There are some real gems in this collection, including a map of the battlegrounds of Shiloh in 1862 and a map detailing the military defenses along a portion of the coast of Texas.

    Device for separating and collecting ultrafine atomized powder from the gas stream of a gas atomizing apparatus comprises a housing having an interior wall oriented at an angle relative to horizontal so as to form a downwardly converging, conical expansion chamber, an inlet conduit communicated to the expansion chamber proximate an upper region thereof for receiving the gas stream, and an outlet proximate a lower region of the expansion chamber. The inlet conduit is oriented at a compound inclined angle (with respect to horizontal) selected to promote separation and collection of powder from the gas stream in the expansion chamber. The compound angle comprises a first entrance angle that is greater than the angle of repose of the powder on the housing interior wall such that any powder accumulation in the inlet conduit tends to flow down the wall toward the outlet. The second angle is selected generally equal to the angle of the housing interior wall measured from the same horizontal plane so as to direct the gas stream into the expansion chamber generally tangent to the housing interior wall to establish a downward swirling gas stream flow in the expansion chamber. A powder collection container is communicated to the outlet of the expansion chamber to collect the powder for further processing.

  8. Psychological aspects of art collecting.

    PubMed

    Baekeland, F

    1981-02-01

    WHAT impels the art collector to acquire works of art? Art historians have steadfastly turned their backs on this question, and psychiatrists and psychoanalysts have not had much to say on the matter either. Patients, after all, do not seek psychiatric services because they are collectors. Yet to anyone at all familiar with art collectors, it is clear that their reasons for collecting are both diverse and complex. They may range from relatively pure ones like those suggested in the passage from Börne, just as applicable to art as to poetry, all the way to the much crasser ones alluded to by Rush. Here I shall have nothing to say about those who collect for profit pure and simple, who may even buy paintings in wholesale lots only to stash them away in a warehouse until they have risen in value. This breed, which has increased apace with the feverish growth of the art business in recent years, does not collect art for art's sake. It is rather to the collector whose motives for collecting are primarily nonmonetary that I want to turn my attention. PMID:7208717

  19. Mapping collective emotions to make sense of collective behavior.

    PubMed

    Taquet, Maxime; Quoidbach, Jordi; de Montjoye, Yves-Alexandre; Desseilles, Martin

    2014-02-01

    While Bentley et al.'s model is very appealing, in this commentary we argue that researchers interested in big data and collective behavior, including the way humans make decisions, must account for the emotional factor. We investigate how daily choice of activities is influenced by emotions. Results indicate that mood significantly predicts people's decisions about what to do next, stressing the importance of emotional state on decision-making. PMID:24572244

    NSDL National Science Digital Library

    The University of Wisconsin System has created this digital collection of resources documenting Belgian settlers in Northeastern Wisconsin. Most of the original materials were gathered in the 1970s by the University of Wisconsin-Green Bay during a project "to record the undocumented historical, social, and cultural legacy of this unique ethnic group." At the search page, the collection is divided into three main areas: Architecture Survey, over 400 pictures of buildings; Oral History Recordings, approximately 50 interviews recorded between 1975 and 1976; and Immigration Histories, 3 book length documents of 100 - 200 pages, each viewable on the Web in an e-book format that allows text searching and leafing through images of the original pages. Keyword searches can also be performed across across all the materials.

  10. The Americana Sheet Music Collection

    NSDL National Science Digital Library

    Based at the Mills Music Library at the University of Wisconsin, the American Sheet Music Collection contains thousands of pieces of sheet music published in the United States before 1900. Many of these items came to the library as gifts, including a significant group of publications that once belonged to composer/publisher Joseph P. Webster. The musical genres included here are impressive, and include airs, folk songs, gallops, hymns, marches, and nocturnes. Visitors can perform a guided search across all of the items, or just search for specific items of note. It's quite interesting to type city names into the search engine as the results may indicate where songs, both well-known and unknown, were published originally. This is an impressive collection and musicologists and others will find much to enjoy here.

  11. Cornell University Political Americana Collection

    NSDL National Science Digital Library

    2010-01-01

    From Teddy Roosevelt to "We Like Ike," the Cornell University Political Americana Collection offers up a cornucopia of presidential promotional and commemorative items dating from 1789 to 1980. All told, there are approximately 5,500 items here, including cartoons, prints, posters, lapel buttons, and leaflets. The majority of this prodigious collection was donated to Cornell by the private collector Susan H. Douglas between 1957 and 1961. Visitors can use the Categories listing to look around via over 150 sections, including Mourning; Monroe, James; and New York. The When category breaks items into presidential election years and it's a great way to get a sense of the changing political fortunes and key issues surrounding each four year contest. Finally, visitors can zoom in and out on each object and also use a variety of embedded tools to look at the rich details of each item.

  12. The Bronx Park Postcard Collection

    NSDL National Science Digital Library

    Over the years since its origins in the late 1880s, the Bronx Park has been expanded several times. In 1891, the city of New York allotted 250 acres of the park to the New York Botanical Garden, and in 1897 assigned 250 more to the Bronx Zoo. This particular digital collection brings together postcards of the grounds held by the Wildlife Conservation Society Library and the Garden's LuEsther T. Mertz Library. The collection here includes over 450 postcards, which visitors can browse by subject headings, including Zoo animals, Paths and walkways, and Bronx River. The Zoo animals area is well worth a look, as it features a range of animals, including a Noah's Ark exhibit, camels, and Indian elephants. It's an amazing archive of documents related to one of the most famous zoos in the United States, and historians and others will find it quite marvelous.

  13. West Virginia Historical Photographs Collection

    NSDL National Science Digital Library

    Like many states, West Virginia has embarked on an ambitious project to digitize a wide range of photographs for use by the general public, historians, and those just curious about the state's history. Created by staff members at the West Virginia University Library system, this online collection brings together 20,000 photographs. The search engine for the site is easy enough to use, but the site might have benefited from a number of subject guides or thematic collections for more casual users. Overall, the site is a real find, as users will enjoy looking through construction photographs of the Personal Rapid Transit system on the campus of West Virginia University, demonstration farm projects in Hancock County, and African American miners at work.

  14. The Belgian-American Collection

    NSDL National Science Digital Library

    While Wisconsin is well-known for its German-American community, some may be surprised to learn that a significant number of Belgians made their way to the Badger State in the 1850s. Most Belgians who came to Wisconsin made their way to the northeastern section of the state and their descendants continue to celebrate the harvest festival known as Kermis as well as a number of other cultural practices. This particular online collection from the University of Wisconsin's Digital Collection provides a host of materials related to this ethnic community. Visitors will note that the materials are divided into six sections, including "Immigration Histories", "Oral History Recordings", and "Belgian Survey Maps". The maps are well worth a look, as they include detailed renderings of nine different Belgian-American farms. Visitors should also not overlook the oral history excerpts and the substantial immigration histories.

  15. Woodson Research Center: Digital Collection

    NSDL National Science Digital Library

    2012-01-13

    The mission of the Woodson Research Center at Rice University is to "support the institutional, research and public service programs of the University." Their collections include the institutional records of the institution, along with materials on United States Southern history, British history and drama, Houston, and business. As part of their work, they have contributed hundreds of items to Rice University's Digital Scholarship Archive. Visitors to the site may wish to start by looking over the William Ward Watkin architectural records sub-collection. Watkin was the first supervising architect for Rice, and visitors can learn about his life's work and the very interesting tunnel system he designed for the school. Moving on, the "early Houston histories and documents" area contains 21 primary documents including "Pen and sunlight sketches of greater Houston: the most progressive metropolis in the South" from 1913 and a fascinating document from 1880 titled "Texas: the best land for the Emigrant."

  16. Collected Works of Abraham Lincoln

    NSDL National Science Digital Library

    Amidst all of his other responsibilities as a lawyer, politician, and father, Abraham Lincoln found time to write. In fact, he wrote quite a bit, and it took scholars decades to assemble the majority of his various published (and unpublished) writings. After working on bringing together his writings, the Abraham Lincoln Association published "The Collected Works of Abraham Lincoln" in 1953. In total, there were eight volumes, and they included Lincoln's correspondence, speeches, and other writings. Recently, the University of Michigan's Digital Library Production Service digitized all eight volumes and placed them online here for the benefit of historians, rhetoricians, and those who are generally enamored of the 16th President. Visitors can perform simple searches, boolean searches, and proximity searches to their hearts' content. Also, they can look over other documents that were digitized for the collection, including Paul M. Angle's "Here I Have Lived: A History of Lincoln's Springfield".

  17. Cincinnati Art Museum: The Collection

    NSDL National Science Digital Library

This website provides interested parties with access to items from their permanent collection, courtesy of a grant from the Harold C. Schott Foundation and the Institute of Museum and Library Services. The works here are organized into ten different themes, including "Photographs," "Art of Africa," and "American Decorative Arts." The "American Decorative Arts" is worth a look, and it contains items from the Rockwood Pottery Company, which was established in Cincinnati in 1880, and is still in business. In the "European Painting & Sculpture" visitors shouldn't miss works like the portrait of Philip II by Titian. Visitors will also appreciate the easy to use search engine and the accession and provenance details which are provided for each item.

  18. Collective credit allocation in science

    E-print Network

    Shen, Hua-Wei

    2014-01-01

    Collaboration among researchers is an essential component of the modern scientific enterprise, playing a particularly important role in multidisciplinary research. However, we continue to wrestle with allocating credit to the coauthors of publications with multiple authors, since the relative contribution of each author is difficult to determine. At the same time, the scientific community runs an informal field-dependent credit allocation process that assigns credit in a collective fashion to each work. Here we develop a credit allocation algorithm that captures the coauthors' contribution to a publication as perceived by the scientific community, reproducing the informal collective credit allocation of science. We validate the method by identifying the authors of Nobel-winning papers that are credited for the discovery, independent of their positions in the author list. The method can also compare the relative impact of researchers working in the same field, even if they did not publish together. The ability...

  19. Students Collecting Real time Data

    NASA Astrophysics Data System (ADS)

    Miller, P.

    2006-05-01

    Students Collecting Real-Time Data The Hawaiian Islands Humpback Whale National Marine Sanctuary has created opportunities for middle and high school students to become Student Researchers and to be involved in real-time marine data collection. It is important that we expose students to different fields of science and encourage them to enter scientific fields of study. The Humpback Whale Sanctuary has an education visitor center in Kihei, Maui. Located right on the beach, the site has become a living classroom facility. There is a traditional Hawaiian fishpond fronting the property. The fishpond wall is being restored, using traditional methods. The site has the incredible opportunity of incorporating Hawaiian cultural practices with scientific studies. The Sanctuary offers opportunities for students to get involved in monitoring and data collection studies. Invasive Seaweed Study: Students are collecting data on invasive seaweed for the University of Hawaii. They pull a large net through the shallow waters. Seaweed is sorted, identified and weighed. The invasive seaweeds are removed. The data is recorded and sent to UH. Remote controlled monitoring boats: The sanctuary has 6 boogie board sized remote controlled boats used to monitor reefs. Boats have a camera with lights on the underside. The boats have water quality monitoring devices and GPS units. The video from the underwater camera is transmitted via a wireless transmission. Students are able to monitor the fish, limu and invertebrate populations on the reef and collect water quality data via television monitors or computers. The boat can also pull a small plankton tow net. Data is being compiled into data bases. Artificial Reef Modules: The Sanctuary has a scientific permit from the state to build and deploy artificial reef modules. High school students are designing and building modules. These are deployed out in the Fishpond fronting the Sanctuary site and students are monitoring them on a weekly basis. Students are also building traditional Hawaiian modules, these being piles of rocks and attaching seaweeds to the rocks with natural fibers. The purpose of all these is to help restore habitat to the fishpond. Monitoring the Fishpond; The fishpond wall is presently being rebuilt. The new wall stands about eight feet high and twelve feet wide. The rocks to rebuild the wall are all being located underwater where the old wall stood. The state has required different information collected as the wall is reconstructed. Students GPS mapped the rock edges of the fallen wall, and will continue to map the progress of the new wall. Other students are monitoring the erosion of the sand dunes that front the edges of the wall and are also looking at the new deposition of sand in the pond. Students are snorkeling, running transects and collecting data on the changing populations of fish, invertebrates and seaweeds in the pond. The wall is only about a forth built and already we are seeing growth in the populations. Students and teachers work with the sanctuary staff to develop projects. The sanctuary loans the equipment to the students and the students collect the data for the sanctuary. It is a great partnership with the schools. The Sanctuary has been given a Congressional Earmark this year to develop marine curriculum for the Department of Education. Projects listed above are part of this curriculum with hopes of many more to be developed. By 2008, all seniors must participate in some type of research project to graduate. The goal is to offer opportunities for many of these projects to become marine science related projects and thus develop a budding new group of marine scientists.

  20. The Harrison Sayre Circus Collection

    NSDL National Science Digital Library

    Circus lore and culture is fascinating. The Harrison Sayre Circus Collection is made up of a vibrant mix of posters and photos documenting the dynamic nature of this blend of showmanship, animal acumen, and acrobatics. These materials were donated to the State University Libraries of Florida by Harrison Sayre, a circus enthusiast. All told, there are over 210 items here culled from Sayre's personal collection. The posters are vibrant and dramatic, and visitors shouldn't miss those for the Big Apple Circus's appearances at Lincoln Center or the rare Polish circus poster by artist Waldemar Swierzy. The photos section contains images of everything from Allen Gold, celebrated lion tamer, to a rather adorable photo of baby elephants lined up before a performance.

  1. G. William Skinner Map Collection

    NSDL National Science Digital Library

    Professor G. William Skinner of the University of Washington was a major theorist of family systems and of spatial social science. Professor Skinner's maps are products of his "lifelong interest in the spatial distribution of social variables." His maps document subjects such as agrarian China, 19th century France, and Japan. Some of the variables he was most interested in included agricultural wages, fertility rates, and the sex ratio in various regions. This remarkable digital collection from the University of Washington Libraries brings together all 1200 maps from the Skinner Collection. Visitors can browse the maps by country and region, subject, or theme. The site also includes several documents by Professor Skinner on his work dealing with hierarchical regional space and a complete list of all the publications related to this work.

  2. Collective dynamics in optomechanical arrays.

    PubMed

    Heinrich, Georg; Ludwig, Max; Qian, Jiang; Kubala, Björn; Marquardt, Florian

    2011-07-22

    Optomechanical systems couple light stored inside an optical cavity to the motion of a mechanical mode. Recent experiments have demonstrated setups, such as photonic crystal structures, that in principle allow one to confine several optical and vibrational modes on a single chip. Here we start to investigate the collective nonlinear dynamics in arrays of coupled optomechanical cells. We show that such "optomechanical arrays" can display synchronization, and that they can be described by an effective Kuramoto-type model. PMID:21867004

  3. IPL General Reference Collection: Education

    NSDL National Science Digital Library

    Though the Internet Public Library's Education meta-page is not as comprehensive in any of its categories as more specialized meta-pages, it covers all grade level education resources, including adult, alternative, K-12, higher ed., and vocational. The home page contains a brief list of major education information and meta-sites. Resources listed have been annotated and the entire IPL Ready Reference Collection is searchable.

  4. Current collection in a magnetoplasma

    NASA Technical Reports Server (NTRS)

    Laframboise, Jim G.; Sonmor, L. J.

    1990-01-01

    The authors present a survey of a very incomplete subject, current collection in a magnetoplasma. The best-developed and simplest theories for current collection are steady-state collisionless theories, and these must be understood before departures from them can be analyzed usefully. Thus, the authors begin with a review of them. The authors include some recent numerical results which indicate that steady-state collisionless Laplace-limit currents remain substantially below the Parker-Murphy (1967) canonical upper bound out to very large electrode potentials, and approach it as a limit only very slowly if at all. Attempts to correct this theory for space-charge effects lead to potential disturbances which extend to infinite distance along the electrode's magnetic shadow, unless collisional effects are also taken into account. However, even a small amount of relative plasma drift motion, such as that involved in a typical rocket experiment, can change this conclusion fundamentally. It is widely believed that time-averaged current collection may be increased by effects of plasma turbulence, and the authors review the available evidence for and against this contention. Steady-state collisionless particle dynamics predicts the existence of a toroidal region of trapped orbits which surrounds the electrode. Light emissions from this region have been photographed, indicating that collisional ionization may also occur there, and this, and/or scattering by collisions or possibly turbulent fluctuations in this region, may also increase current collection by the electrode. The authors also discuss effects on particle motions near the electrode, associated with breakdown of magnetic insulation in the region of large electric fields near it.

  6. San Francisco Historical Photograph Collection

    NSDL National Science Digital Library

    In the 1936 film, "San Francisco" Jeannette MacDonald sings the film's title song, which of course includes the Gus Kahn-penned lyric "San Francisco, welcome me home again/I'm not at home to go roaming no more." For those who might be pining for Baghdad by the Bay (or for images from the infamous earthquake in 1906), this online collection from the San Francisco Public Library will be most welcome. All told, the San Francisco Historical Photograph Collection contains more than 250,000 photographs of San Francisco and California, although not all of these photographs are available online here. Visitors should begin their voyage through these images by using their search engine, which allows them to search by photographer, subject index, or by date. Perhaps the most novel way to search the images is to look through the photos by using an interactive map of the entire city. Here visitors can find photographs of the historic Moulin Rouge nightclub in the historic Barbary Coast area, or move on over to Sutro Heights over on the Pacific Ocean. For those who might be feeling a bit less adventurous, there are a number of thematic collections, including "Picture This: Family Photographs of Everyday San Francisco".

  7. Electrospray Collection of Lunar Dust

    NASA Technical Reports Server (NTRS)

    Dziekan, Michael

    2012-01-01

    A report describes ElectroSpray Ionization based Electrostatic Precipitation (ESIEP) for collecting lunar dust particles. While some HEPA filtration processes may remove a higher fraction (>99.9 percent) of the particles, the high efficiency may not be appropriate from an overall system standpoint, especially in light of the relatively large power requirement that such systems demand. The new electrospray particle capture technology is described as a variant of electrostatic precipitation that eliminates the current drawbacks of electrostatic precipitation. The new approach replaces corona prone field with a mist of highly charged micro-droplets generated by electrospray ionization (ESI) as the mechanism by which incoming particles are attracted and captured. In electrospray, a miniscule flow rate (microliters/minute) of liquid (typically water and a small amount of salt to enhance conductivity) is fed from the tip of a needle held at a high voltage potential relative to an opposite counter electrode. At sufficient field strength, a sharp liquid meniscus forms , which emits a jet of highly charged droplets that drift through the surrounding gas and are collected on the walls of a conductive tube. Particles in the gas have a high probability of contact with the droplets either by adhering to the droplets or otherwise acquiring a high level of charge, causing them to be captured on the collecting electrode as well. The spray acts as a filtration material that is continuously introduced and removed from the gas flow, and thus can never become clogged.

  8. Collective migration and cell jamming

    PubMed Central

    Sadati, Sanaz Monirosadat; Qazvini, Nader Taheri; Krishnan, Ramaswamy; Park, ChanYoung; Fredberg, Jeffrey J.

    2013-01-01

    Our traditional physical picture holds with the intuitive notion that each individual cell comprising the cellular collective senses signals or gradients and then mobilizes physical forces in response. Those forces, in turn, drive local cellular motions from which collective cellular migrations emerge. Although it does not account for spontaneous noisy fluctuations that can be quite large, the tacit assumption has been one of linear causality in which systematic local motions, on average, are the shadow of local forces, and these local forces are the shadow of the local signals. New lines of evidence now suggest a rather different physical picture in which dominant mechanical events may not be local, the cascade of mechanical causality may be not so linear, and, surprisingly, the fluctuations may not be noise as much as they are an essential feature of mechanism. Here we argue for a novel synthesis in which fluctuations and non-local cooperative events that typify the cellular collective might be illuminated by the unifying concept of cell jamming. Jamming has the potential to pull together diverse factors that are already known to contribute but previously had been considered for the most part as acting separately and independently. These include cellular crowding, intercellular force transmission, cadherin-dependent cell-cell adhesion, integrin-dependent cell-substrate adhesion, myosin-dependent motile force and contractility, actin-dependent deformability, proliferation, compression and stretch.

    This extremely well-researched website offers a unique perspective on the Middle East, by presenting multi- and interdisciplinary documents, books, data, journal and newspaper articles that are devoted solely to water. The Middle East Water Collection website, presented by the Oregon State University libraries, examines the very complex issues that water presents, "to provide a greater understanding of the multi-disciplinary nature of water and its interactions with politics, development, social issues, culture and religion." Additionally, the online collection is just a part of the complete 9000 item collection available at Oregon State University. Visitors can search via "Region/Country", "Basins", "Subjects", or "Full Text" by using the drop down boxes on the left hand side of the homepage. The "My Favorites" tab near the top of the page allows visitors to save any of the items to their own favorites page, simply by clicking "Add to Favorites" at the bottom of the entry they want to save. A pop-up window will display indicating the item has been saved to the visitors' page.

  10. R. Buckminster Fuller Digital Collection

    NSDL National Science Digital Library

    It is hard to classify R. Buckminster Fuller, but at the very least, it is fair to say he was an architect, a planner, an engineer, an inventor, and a Renaissance man in the best sense of the phrase. With support from the Save America's Treasures Program, Stanford University has seen fit to digitally reformat a wide range of very valuable audio and video materials culled from their R. Buckminster Fuller Collection. First-time visitors will need to create a login password before accessing the materials, but never fear, as it only takes a moment. After that, they will have complete access to all the materials within the collection. It's not a bad idea to start by looking through the "Browse" area first, and here they will find interviews with Fuller, along with the "Being with Bucky" seminars. Those who are completely unfamiliar with Fuller's work may wish to start by clicking on the "Exploring Bucky" area. Here they can read over brief answers to "Who was Bucky Fuller?" and "What is a geodesic dome?" For architects, engineers, and many others, this collection will be quite a find.

  16. Collective Dynamics in Sparse Networks

    NASA Astrophysics Data System (ADS)

    Luccioli, Stefano; Olmi, Simona; Politi, Antonio; Torcini, Alessandro

    2012-09-01

    The microscopic and macroscopic dynamics of random networks is investigated in the strong-dilution limit (i.e., for sparse networks). By simulating chaotic maps, Stuart-Landau oscillators, and leaky integrate-and-fire neurons, we show that a finite connectivity (of the order of a few tens) is able to sustain a nontrivial collective dynamics even in the thermodynamic limit. Although the network structure implies a nonadditive dynamics, the microscopic evolution is extensive (i.e., the number of active degrees of freedom is proportional to the number of network elements).

    Appleton, Wisconsinâ??s, Lawrence University continues to work diligently to digitize its library holdings that might be of interest to the general public. These collections include items from the department of theatre arts, along with items from Lux, the online home for the universityâ??s scholarly and creative works. It's a great way to learn about some of its most compelling projects, including wonderful honor projects, such as "Learning from Experience: A Philosophical Perspective." Moving on, the theatre arts area contains images, programs and other bits of ephemera from shows like Cabaret, Cinderella, and much more.

  18. The neurobiology of collective action

    PubMed Central

    Zak, Paul J.; Barraza, Jorge A.

    2013-01-01

    This essay introduces a neurologically-informed mathematical model of collective action (CA) that reveals the role for empathy and distress in motivating costly helping behaviors. We report three direct tests of model with a key focus on the neuropeptide oxytocin as well as a variety of indirect tests. These studies, from our lab and other researchers, show support for the model. Our findings indicate that empathic concern, via the brain's release of oxytocin, is a trigger for CA. We discuss the implications from this model for our understanding why human beings engage in costly CA. PMID:24311995

  19. Sensorized waste collection container for content estimation and collection optimization.

    PubMed

    Vicentini, F; Giusti, A; Rovetta, A; Fan, X; He, Q; Zhu, M; Liu, B

    2009-05-01

    The concurrent effects of a fast national growth rate, of a large and dense residential area and a pressing demand for urban environmental protection create a challenging framework for waste management in Pudong New Area, Shanghai. The complexity of context and procedures is indeed a primary concern of local municipal authorities due to problems related to the collection, transportation and processing of residential solid waste. In order to design and implement a suitable urban solid waste system, the first task is to forecast the quantity and variance of solid waste as it relates to residential population, consumer index, season, etc. The system here discussed addresses exactly these issues, by means of an intelligent, sensorized container. The container has been prepared and tested in the Pudong New Area, Shanghai. PMID:19103480

    2012-02-10

    Senator William Proxmire represented the state of Wisconsin in the U.S. Senate from 1957 to 1989. During his time in office, he championed human rights, consumer rights, and honest government while opposing federal waste and corruption. This collection from the Wisconsin Historical Society presents over 7,500 pages of manuscripts, press releases, newsletters, photographs, articles, interviews, and correspondence selected from his papers, which he donated in 1989. Users may wish to start by clicking on the Biography area to read a profile of Senator Proxmire. Moving along, the Interviews area features 40 interviews with the friends, family, colleagues, and former staff members that knew Proxmire. Visitors should then click Browse to look through the folders of the collection, which include biographical notes, jokes, images, and press releases. One place that should not be overlooked is the Golden Fleece Awards folder, which contains information about those agencies and areas of the federal government that "won" awards from Senator Proxmire for their misuse and waste of taxpayer dollars.

  1. Selective altruism in collective games

    NASA Astrophysics Data System (ADS)

    Zappalà, Dario A.; Pluchino, Alessandro; Rapisarda, Andrea

    2014-09-01

    We study the emergence of altruistic behaviour in collective games. In particular, we take into account Toral's version of collective Parrondo's paradoxical games, in which the redistribution of capital between agents, who can play different strategies, creates a positive trend of increasing capital. In this framework, we insert two categories of players, altruistic and selfish ones, and see how they interact and how their capital evolves. More in detail, we analyse the positive effects of altruistic behaviour, but we also point out how selfish players take advantage of that situation. The general result is that altruistic behaviour is discouraged, because selfish players get richer while altruistic ones get poorer. We also consider a smarter way of being altruistic, based on reputation, called "selective altruism", which prevents selfish players from taking advantage of altruistic ones. In this new situation it is altruism, and not selfishness, to be encouraged and stabilized. Finally, we introduce a mechanism of imitation between players and study how it influences the composition of the population of both altruistic and selfish players as a function of time for different initial conditions and network topologies adopted.

  2. Open Collections Program: Women Working

    NSDL National Science Digital Library

    Established in November 2002 with the generous support of the William and Flora Hewlett Foundation, the Open Collections Program at Harvard University Library is designed "to increase the availability and use of textual and visual historical resources for teaching, learning, and research." The first project within the terms of this impressive remit is the Women Working, 1870-1930 digitized collection. Within this broad topical area, the documents currently available here are largely centered around the experience of working women during this period in Boston. Currently, over 450 documents are available for perusal, although at the completion of the project, over 3000 documents will be publicly available through this site. Visitors may browse through the New Additions area, look through the materials by topic (such as home labor, arts, or business), or perform a full text search. Also, users should make sure and browse through the diary of one H. Greene, a woman who lived on her family farm in Seneca County, Ohio, and who offers her recollections of the year 1887.

  3. Vietnam War Era Ephemera Collection

    NSDL National Science Digital Library

    The traumatic and unsettled backdrop of social and cultural change throughout the United States in the late 1960s and early 1970s will not soon be forgotten by any of those persons who lived through that period. Some groups of people came together under the banner of the women's liberation movement, and still others surrounded themselves in the unifying guise of ethnic solidarity and pride, such as those who participated in the American Indian Movement. No one ongoing event garnered as much attention, however, as the Vietnam War did. That particular event inspired a host of posters, handouts, and other printed ephemera that may have quickly disappeared, as do many pieces of material culture often do. Fortunately, the University of Washington Libraries Digital Collections division has created this online archive which brings many of these documents together in one place. The documents are divided into thematic categories, such as racism, socialism, farm workers, gay rights, and religion. There are some real compelling documents on the site, and those with a penchant for social and cultural history will enjoy this fine collection.

  4. Collective credit allocation in science

    PubMed Central

    Shen, Hua-Wei; Barabási, Albert-László

    2014-01-01

    Collaboration among researchers is an essential component of the modern scientific enterprise, playing a particularly important role in multidisciplinary research. However, we continue to wrestle with allocating credit to the coauthors of publications with multiple authors, because the relative contribution of each author is difficult to determine. At the same time, the scientific community runs an informal field-dependent credit allocation process that assigns credit in a collective fashion to each work. Here we develop a credit allocation algorithm that captures the coauthors’ contribution to a publication as perceived by the scientific community, reproducing the informal collective credit allocation of science. We validate the method by identifying the authors of Nobel-winning papers that are credited for the discovery, independent of their positions in the author list. The method can also compare the relative impact of researchers working in the same field, even if they did not publish together. The ability to accurately measure the relative credit of researchers could affect many aspects of credit allocation in science, potentially impacting hiring, funding, and promotion decisions.

  5. Brooker Collection at Boston College

    NSDL National Science Digital Library

    A number of years back, the Boston College Law Library received a tremendous gift from Robert E. Brooker, III. Over many decades, Brooker had assembled some 2500 documents and manuscripts that tell the story of land use and legal systems in Boston and the New England area from 1716 to 1930. These documents include deeds of lands, contracts for goods and services, wills, letters, and estate inventories. Visitors to this collection can view all of these documents, and legal historians, geographers, and historians of New England will have a field day with the offerings here. One particularly note-worthy item is item #1013, which is a beautiful deed signed in October 1738 by Isaac Harris. It is the oldest deed in the collection, and it includes a transcript for those who don't want to squint while looking at the screen. Of course, visitors can also search through all of the items, and they are encouraged to use the viewing tools as well.

  6. Collective behavior of biological cells

    NASA Astrophysics Data System (ADS)

    Silberzan, Pascal

    2010-03-01

    Interacting biological cells can exhibit collective behaviors that our knowledge at the scale of the single cell cannot fully explain. These highly non-linear systems strongly depend on the boundary conditions on which microfabrication techniques offer a good control. A first example is given by chemotactic Escherichia coli bacteria swimming in liquid medium. These cells communicate by expressing soluble chemoattractants which gives rise to spatial concentration heterogeneities that can be evidenced particularly well in micro-geometries. In particular, when the bacteria are concentrated at the extremity of a microchannel, a concentration wave appears and propagates along the channel. We will discuss new results obtained on this system, in particular by studying closely the details of the trajectories of single bacteria. The situation with eukaryotic epithelial cells, although basically different, presents some formal similarities. By using microfabricated micro-stencils to trigger the collective migration, we observe long-range coordinated displacements well within the monolayer. In parallel, the edges of these migrating monolayers roughen drastically and exhibit a strong directional fingering where a ``leader cell'', that exhibits a clearly non-epithelial phenotype, leads the others. In these fingers, the velocity field, as well as the orientation and polarization of the cells align with the fingers but are described by different order parameters and kinetics. The exact role of the leader can be clarified by mapping the traction forces exerted by the cells using a microfabricated array of force sensors.

  10. Frank M. Hohenberger Photograph Collection

    NSDL National Science Digital Library

    2012-06-22

    For 47 years, photographer and newspaperman Frank Hohenberger roamed around the highways and byways of Brown County, Indiana recording the life and times of this unique corner of the state. From time to time he also made forays into Kentucky, South Carolina, New England, Canada and Mexico. Once, he offered the memorable observation that "pictures speak the only language all mankind can understand." Visitors to this site created by Indiana University's Digital Library Program can browse the photos by date or by series. The series option is quite nice, as visitors can scan through his numerous trips. The "New England, 1950" series, for instance, features images of old bars, the waterfall at Kent House in Quebec, and hand-painted signs. It's a beautiful collection and one that may inspire photographers and others with an eye for capturing landscapes near and far.

  11. MAD data collection - current trends.

    SciTech Connect

    Dementieva, I.; Evans, G.; Joachimiak, A.; Sanishvili, R.; Walsh, M. A.

    1999-09-20

    The multi-wavelength anomalous diffraction, or MAD, method of determining protein structure is becoming routine in protein crystallography. An increase in the number of tuneable synchrotrons beamlines coupled with the widespread availability position-sensitive X-ray detectors based on charged-coupled devices and having fast readout raised MAD structure determination to a new and exciting level. Ultra-fast MAD data collection is now possible. Recognition of the value of selenium for phasing protein structures and improvement of methods for incorporating selenium into proteins in the form of selenomethionine have attracted greater interest in the MAD method. Recent developments in crystallographic software are complimenting the above advances, paving the way for rapid protein structure determination. An overview of a typical MAD experiment is described here, with emphasis on the rates and quality of data acquisition now achievable at beamlines developed at third-generation synchrotrons sources.

    Scott, Jill R; Groenewold, Gary S

    2013-12-24

    A device for sampling chemical compounds from fixed surfaces and related methods are disclosed. The device may include a vacuum source, a chamber and a sorbent material. The device may utilize vacuum extraction to volatilize the chemical compounds from a fixed surface so that they may be sorbed by the sorbent material. The sorbent material may then be analyzed using conventional thermal desorption/gas chromatography/mass spectrometry (TD/GC/MS) instrumentation to determine presence of the chemical compounds. The methods may include detecting release and presence of one or more chemical compounds and determining the efficacy of decontamination. The device may be useful in collection and analysis of a variety of chemical compounds, such as residual chemical warfare agents, chemical attribution signatures and toxic industrial chemicals.

  13. Hyde Park Herald Digital Collections

    NSDL National Science Digital Library

    Hyde Park is a well-known urban neighborhood eight miles south of Chicago's Loop, and residents in and around the neighborhood have a long tradition of independent journalism. The Hyde Park Herald was started in 1882, and it documented the community's earliest history, including the years before the neighborhood was annexed to Chicago. Recently, a group of concerned citizens donated money to digitize the newspaper's back issues, and it was done to celebrate the leadership of Bruce Sagan, who has published the newspaper since 1953. Visitors can view the newspaper from 1882 to the present day, and despite a gap between the years 1889 and 1918, the coverage is quite good. Some good starting points include the WWII years and the late 1950s, which was when the first urban renewal project started in the neighborhood. Also, visitors may wish to perform a detailed search across the entire collection and then can also learn a bit more about the paper's history here.

    Geisen, Jurgen

    Authored by Jurgen Geisen, this site has more than sixty-five Java applets. The interactive resources provide detailed solar and lunar data and the daily and annual path of the sun and moon for any location. More specifically, the collection has fourteen applets concerning the moon, and another twelve which solely describe sundials. Six other resources focus on topics such as: the Venus transit observer, phases of Mercury and Venus, geocentric motion and many more. The author has made an outline for instructors in the order he best feels the applets should be introduced. The plan consists of seven different parts and careful lists of the different topics each section. This is a great resource for effective interactive online learning.

  15. Priest Lake Museum Association Collection

    NSDL National Science Digital Library

    What is this place, this Priest Lake, Idaho? It's a resort, it's a way of life, and it's a special area to many Idahoans. This digital collection from the University Idaho Library was made possible via the holdings of the Priest Lake Museum Association. The 380 photos here depict family, community, and business life in the Priest Lake area from around 1880 to 1950. The images bring this certain time and place to life, highlighting fishing at Two Mouth Creek, horse-drawn sledding, and general outdoor merry-making. Most interesting are the images of Nell Shipman, a silent film star who brought her own production company and zoo to the area. The photos can be viewed using the map, timeline, or interactive word cloud, which is rather fun.

  16. Latin American Pamphlet Digital Collection

    NSDL National Science Digital Library

    Over the centuries, thousands of pamphlets have been published to serve various purposes. Some have been preserved by individuals and prescient institutions, but countless others have disappeared forever. Harvard University's Widener Library has over 5000 pamphlets from 19th and 20th century Latin America, and until recently, they remained uncataloged and mostly inaccessible. Visitors to this site can browse the collection by title, subject, name, and genre. The materials offered here range from documents on accounting practices to those dealing with yellow fever. Additionally, visitors looking for descriptive documents that describe unexplored territories and the relationship between church and state will not be disappointed. The site also contains a nice help feature and visitors can also email questions to staff members at the library.

  17. Finnish National Gallery: Art Collections

For example, browse by themes including Abstract, Non-representational Art; Religion and Magic; Nature; or History; as well as time period, or types of art from Painting to Textile art. In addition, searches can be conducted by artist name or work of art, limited by type of work, and, since the search encompasses several museums, location. There are also a couple of "Routes" through the collection - prearranged paths, one of animal images, fourteen works of art and/or paired works to "give you a brief insight into what artists at different times have thought of ... animals", and another called "To the forest", featuring 19 artworks inspired by the woods.

  18. Collective excitations of supersymmetric plasma

    NASA Astrophysics Data System (ADS)

    Czajka, Alina; Mrówczy?ski, Stanis?aw

    2011-02-01

    Collective excitations of N=1 supersymmetric electromagnetic plasma are studied. Since the Keldysh-Schwinger approach is used, not only equilibrium but also nonequilibrium plasma, which is assumed to be ultrarelativistic, is under consideration. The dispersion equations of photon, photino, electron, and selectron modes are written down and the self-energies, which enter the equations, are computed in the hard loop approximation. The self-energies are discussed in the context of effective action which is also given. The photon modes and electron ones appear to be the same as in the usual ultrarelativistic plasma of electrons, positrons, and photons. The photino modes coincide with the electron ones and the selectron modes are as of a free relativistic massive particle.

  19. The Sir Henry Dryden Collection

    NSDL National Science Digital Library

    2007-01-01

    Like many of his peers who were "to the manor born", Sir Henry Dryden was a 19th century Brit who was fascinated with archaeology and the world of antiquity. Before his death in 1899, he produced thousands of architectural and archaeological drawings based on the things he saw and studied during his travels around Britain and Europe. Recently, a consortium of institutions including the University College Northampton digitized a number of Dryden?s drawings, and subsequently placed them online here. Visitors can browse the materials by date, or by topics that include archaeology, arms and armor, and church architecture. The heraldry area within arms and armor is worth a look, as it contains some highly detailed renderings of various coats of arms and heraldic shields. Overall, the collection provides an interesting look into one man's passion for the built environment and the world of 19th century Britain.

  20. Scavenger Hunt: A Group Collection

    NSDL National Science Digital Library

    Donnell Tinkelenberg

    2009-01-01

    In this activity, learners are divided into teams. Half the team works as "collectors" and the other half works as "curators." Collectors go outside and search for various organisms as well as the evolutionary and ecological relationships between the organisms. Collectors earn points based on the complexity of the organisms they find. Examples include consumer, bryophyte, spores, simple food chains, communities, etc. The list of organisms to find can be tailored to the local environment learners will investigate. The curators identify and display the items in folders (animals, fungi, and protists are drawn, not collected). This activity can be used at the end of biology class and/or to assess learners' knowledge of classification, biology of organisms, evolution, ecological relationships, microscope use, and use of research tools.
