The timing and reproductive output of the commercial sea cucumber Holothuria scabra on the Kenyan coast  

NASA Astrophysics Data System (ADS)

The sea cucumber Holothuria scabra is a widely distributed and economically important species that has been harvested in Kenya for decades. No previous studies have been carried out on the reproduction of this species in Kenya. Standard gonad index methods were used to analyze reproductive patterns of individuals collected monthly in 1998-1999, 2000-2001 and 2006-2007. Morphological characteristics, gonad tubule lengths and fecundity were also measured. Mean monthly gonad indices were significantly correlated between males and females indicating synchronous gonad development between the sexes. Gonad indices showed a biannual pattern that was consistent in all three years with a minor spawning event occurring between August and September and a major spawning event between November and December. The pattern of gonad growth showed significant variability between years and between months. Temporal changes in gonad growth correlated significantly with gonad tubule length and absolute fecundity. Monthly gonad indices also correlated significantly with monthly measurements of air temperature and light suggesting a possible role for both factors in timing gametogenesis and spawning. There was a shift in sex ratio from unity in the 1998-1999 and 2000-2001 samples to significantly more males in the 2006-2007 samples, as well as a significant reduction in mean sizes (body wall weight) and reproductive output (gonad index) which suggests that the reproductive success of this species is potentially negatively affected by fishing.

Evaluation of antibacterial, antifungal and cytotoxic effects of Holothuria scabra from the North Coast of the Persian Gulf.  


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).

Acid-base physiology response to ocean acidification of two ecologically and economically important holothuroids from contrasting habitats, Holothuria scabra and Holothuria parva.  


Sea cucumbers are dominant invertebrates in several ecosystems such as coral reefs, seagrass meadows and mangroves. As bioturbators, they have an important ecological role in making available calcium carbonate and nutrients to the rest of the community. However, due to their commercial value, they face overexploitation in the natural environment. On top of that, occurring ocean acidification could impact these organisms, considered sensitive as echinoderms are osmoconformers, high-magnesium calcite producers and have a low metabolism. As a first investigation of the impact of ocean acidification on sea cucumbers, we tested the impact of short-term (6 to 12 days) exposure to ocean acidification (seawater pH 7.7 and 7.4) on two sea cucumbers collected in SW Madagascar, Holothuria scabra, a high commercial value species living in the seagrass meadows, and H. parva, inhabiting the mangroves. The former lives in a habitat with moderate fluctuations of seawater chemistry (driven by day-night differences) while the second lives in a highly variable intertidal environment. In both species, pH of the coelomic fluid was significantly negatively affected by reduced seawater pH, with a pronounced extracellular acidosis in individuals maintained at pH 7.7 and 7.4. This acidosis was due to an increased dissolved inorganic carbon content and pCO2 of the coelomic fluid, indicating a limited diffusion of the CO2 towards the external medium. However, respiration and ammonium excretion rates were not affected. No evidence of accumulation of bicarbonate was observed to buffer the coelomic fluid pH. If this acidosis stays uncompensated for when facing long-term exposure, other processes could be affected in both species, eventually leading to impacts on their ecological role. PMID:25028324

Cytotoxic and Apoptosis-Inducing Activity of Triterpene Glycosides from Holothuria scabra and Cucumaria frondosa against HepG2 Cells  

PubMed Central

The cytotoxic effects of thirteen triterpene glycosides from Holothuria scabra Jaeger and Cucumaria frondosa Gunnerus (Holothuroidea) against four human cell lines were detected and their cytotoxicity-structure relationships were established. The apoptosis-inducing activity of a more potent glycoside echinoside A (1) in HepG2 cells was further investigated by determining its effect on the morphology, mitochondrial transmembrane potential (??m) and mRNA expression levels of the apoptosis-related genes. The results showed that the number of glycosyl residues in sugar chains and the side chain of aglycone could affect their cytotoxicity towards tumor cells and selective cytotoxicity. 1 significantly inhibited cell viability and induced apoptosis in HepG2 cells. 1 also markedly decreased the ??m and Bcl-2/Bax mRNA express ratio, and up-regulated the mRNA expression levels of Caspase-3, Caspase-8 and Caspase-9 in HepG2 cells. Therefore, 1 induced apoptosis in HepG2 cells through both intrinsic and extrinsic pathway. These findings could potentially promote the usage of these glycosides as leading compounds for developing new antitumor drugs. PMID:25062508

Molecular and morphological discrimination between an invasive ascidian, Ascidiella aspersa, and its congener A. scabra (Urochordata: Ascidiacea).  


The solitary ascidian Ascidiella aspersa (Müller, 1776) has sometimes been regarded as conspecific with A. scabra (Müller, 1776), although previous detailed morphological comparisons have indicated that the two are distinguishable by internal structures. Resolution of this taxonomic issue is important because A. aspersa has been known as a notoriously invasive ascidian, doing much damage to aquaculture e.g. in Hokkaido, Japan. We collected many specimens from European waters (including the Swedish coast, near the type localities of these two species) and Hokkaido, Japan (as an alien population) and made molecular phylogenetic analyses using the mitochondrial cytochrome c oxidase subunit I (COI) gene, and found that in terms of COI sequences all the analyzed specimens were clustered into two distinct groups, one of which is morphologically referable to A. aspersa and the other to A. scabra. Thus, these two species should be regarded as distinct from each other. PMID:24601780

Polyhydroxy cyclohexanols from a Dendrodochium sp. fungus associated with the sea cucumber Holothuria nobilis Selenka.  


Four cyclohexanol analogues, dendrodochols A-D (1-4), were isolated from a Dendrodochium sp. fungus associated with the sea cucumber Holothuria nobilis Selenka collected from the South China Sea. The structures were elucidated by means of detailed spectroscopic analysis. The absolute configurations were assigned using a solution TDDFT/ECD calculation approach and the modified Mosher's method. In an in vitro bioassay, these compounds exhibited no growth inhibition activity against the A549 and MG63 cell lines. Dendrodochols 1 and 3 exhibited modest antifungal activity against Candida strains, Cryptococcus neoformans, and Trichophyton rubrum, whereas 2 and 4 showed no activity against the tested strains.

Effects of seven diets on the population dynamics of laboratory cultured Tisbe holothuriae Humes (Copepoda, Harpacticoida)  

NASA Astrophysics Data System (ADS)

The harpacticoid copepod Tisbe holothuriae was collected from Saronicos Gulf (Greece) and reared under constant laboratory conditions. In order to study the effects of food on the population dynamics, seven diets were tested: the seaweed Ulva; five artificial compound feeds: the liquid Fryfood® (Waterlife), a powder of Mytilus, yeast, soya and Spirulina, respectively; and a mixed diet consisting of Ulva and Fryfood. The life cycle parameters (mortality, sex ratio, generation time, offspring production) were measured, and the demographic variables [mean generation time (T), net reproductive rate (Ro), and intrinsic rate of natural increase (rm)] were determined. As to their efficiency regarding population dynamics, the diets ranked as follows: (1) Ulva+Fryfood, (2), Ulva, (3) Fryfood, (4) Mytilus, (5) soya, (6) yeast, and (7) Spirulina. In this order they cause a progressive increase of both larval mortality and generation time, a progressive decrease of sex ratio, number of offspring per egg sac, number of egg sacs per female and, consequently, of Ro and rm. The observed differences between diets were most pronounced with respect to offspring production. Of the compound diets, those containing animal extracts were more efficient than those containing vegetable materials. Ulva plays an important role in the nutrition of T. holothuriae, favouring offspring production as well as larval survival, development and pigmentation. Ulva in combination with Fryfood led to a greater copepodid survival and offspring production. This mixed diet proved to be the most favourable for rearing the Greek population of t. holothuriae, resulting in an efficient intrinsic rate of natural increase (rm=0.304) of the population.

Differential proteomic response to heat stress in thermal Agrostis scabra and heat-sensitive Agrostis stolonifera.  


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].

AChE and EROD activities in two echinoderms, Holothuria leucospilota and Holoturia atra (Holothuroidea), in a coral reef (Reunion Island, South-western Indian Ocean).  


AChE and EROD activities were investigated in two holothurian species, Holothuria leucospilota and Holoturia atra, from a tropical coral reef. These organisms were collected from 3 back-reef stations, where temperature and salinity were homogeneous. The activity levels of both AChE and EROD varied significantly between the two species, but were in the range of values determined in other echinoderm species. AChE activity levels were higher in the longitudinal muscle than in the tentacle tegument. Among the several tissues tested, the digestive tract wall exhibited higher EROD activity levels. Sex did not influence AChE and EROD activity levels in both species. Animal biomass and EROD activity levels were only correlated in the tegument tissue of H. atra, and we hypothesize a possible influence of age. EROD activity did not show intraspecific variability. A significant relationship was found between AChE activity and Cuvierian tubules time of expulsion in Holothuria leucospilota. Individuals collected at the southern site presented both lower AChE activity levels and Cuvierian tubules time of expulsion, indicating possible neural disturbance. More information on holothurians biology and physiology is needed to further assess biomarkers in these key species. This study is the first of its kind performed in the coastal waters of Reunion Island and data obtained represent reference values. PMID:20390918

Antibacterial and Antifungal Activity of Holothuria leucospilota Isolated From Persian Gulf and Oman Sea  

PubMed Central

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

Development and characterization of polymorphic microsatellite loci in the sea cucumber Holothuria leucospilota.  


Holothuria leucospilota is a tropical holothurian species that is widely distributed in the tropical and sub-tropical India-Western Pacific Region. Eight polymorphic microsatellite loci were developed from H. leucospilota by using the protocol fast isolation by amplified fragment length polymorphism of sequences containing repeats and tested in 30 individuals from Hainan Island in China. The number of alleles was 2-6 and polymorphism information content ranged from 0.371-0.694. The levels of expected and observed heterozygosities varied from 0.3913-0.6701 and from 0.1154-0.7000, respectively. No significant linkage disequilibrium was detected for any pairwise combination of loci. Only loci YZHS1-42 deviated from Hardy-Weinberg equilibrium. These polymorphic microsatellite loci may be useful for germplasm conservation of H. leucospilota. PMID:25729989

Population dynamics of Tisbe holothuriae (Copepoda; Harpacticoida) in exploited mass cultures  

NASA Astrophysics Data System (ADS)

Three cultures of Tisbe holothuriae in 101 tanks were harvested each 7 or 10 to 12 days at a rate of 50%. The most frequently harvested culture showed the highest yield. At lower exploitation rates a higher rate of sea water renewal resulted in a higher production. In the cultures, variations in sex ratio, ovigerous rate, and number of eggs per sac contributed to a stabilization of the egg production. More frequent harvesting favoured the ovigerous rate and a higher renewal rate of the medium resulted in more eggs per sac. The growth rate of the population was estimated from calculated values for birth rate and death rate, and this estimate was compared with the observed growth rate. The quality of the sea water medium in mass cultures was investigated and discussed in its effects on population dynamics.

Identification of heat stress-responsive genes in heat-adapted thermal Agrostis scabra by suppression subtractive hybridization.  


To gain insights into molecular mechanisms of grass tolerance to heat stress, we constructed a suppression subtractive cDNA library to identify heat-responsive genes for a C(3) grass species, thermal Agrostis scabra adapted to heat stress in geothermal areas in Yellowstone National Park. Plants were exposed to 20 degrees C (control) or 35 degrees C for 12d. The SSH analysis was performed with control samples as the driver and heat-stressed samples as the tester. Differentially expressed cDNA fragments were cloned to screen the heat up-regulated library. The SSH analysis identified 120 non-redundant putative heat-responsive cDNAs out of 1180 clones. Genes with homology to known proteins were categorized into six functional groups, with the largest group of genes involved in stress/defense, followed by the group of genes related to protein metabolism. Immunoblot analysis confirmed increases in transcripts of selected genes under heat stress. Transcripts of seven and eight genes were strongly enhanced or induced in shoots and roots, respectively, while two genes were only induced in roots under heat stress. The heat up-regulated genes in thermal A. scabra adapted to long-term heat stress are potential candidate genes for engineering stress-tolerant grasses and for revealing molecular mechanisms of grass adaptation to heat stress.

Neuroanatomy of the tube feet and tentacles in Holothuria glaberrima (Holothuroidea, Echinodermata)  

PubMed Central

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

Discovery of Novel Saponins from the Viscera of the Sea Cucumber Holothuria lessoni  

PubMed Central

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.

Antioxidant and cytotoxic properties of two sea cucumbers, Holothuria edulis lesson and Stichopus horrens Selenka.  


Sea cucumbers are marine invertebrates of the phylum of Echinodermata that have been used in Asian traditional medicine since ancient times. This study was conducted to investigate the antioxidant and cytotoxic properties of aqueous and organic extracts from two sea cucumber species, Holothuria edulis Lesson (Holothuriidae) and Stichopus horrens Selenka (Stichopodidae). Antioxidant activities of the extracts were evaluated by DPPH· and ?-carotene bleaching assays, while MTT and trypan blue exclusion assays were used to demonstrate the cytotoxic effects of the extracts against two human cancer cell lines, non-small cell lung cancer cells (A549) and esophageal cancer cells (TE1). The results showed that both aqueous and organic extracts of H. edulis were able to scavenge DPH radical (IC50 at 2.04 mg/ml and 8.73 mg/ml, respectively). Aqueous and organic extracts of S. horrens inhibited 79.62% and 46.66% of ?-carotene oxidation by linoleate free radical. On the other hand, the organic extract of S. horrens exhibited the highest cytotoxic effects against A549 and TE1 cancer cells giving IC50 at 15.5 and 4.0 ?g/ml, respectively. In conclusion, the present study revealed that H. edulis and S. horrens contain promising levels of antioxidant and cytotoxic natural products that might be used for cancer prevention and treatment.

Isolation and Characterization of Adhesive Secretion from Cuvierian Tubules of Sea Cucumber Holothuria forskĺli (Echinodermata: Holothuroidea)  

PubMed Central

The sea cucumber Holothuria forskĺli 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. forskĺli. 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

Diet of Littoraria scabra, while vertically migrating on mangrove trees: Gut content, fatty acid, and stable isotope analyses  

NASA Astrophysics Data System (ADS)

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.

LPS-Induced Genes in Intestinal Tissue of the Sea Cucumber Holothuria glaberrima  

PubMed Central

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 Sulfates from the Body Wall of the Sea Cucumber Holothuria forskali  

PubMed Central

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

Influence of three bacteria strains on the population dynamics of Tisbe holothuriae (Copepoda, Harpacticoida)  

NASA Astrophysics Data System (ADS)

The influence of three bacteria strains (Helgo 21, NCMB 308 and NCMB 13) on the life cycle of Tisbe holothuriae Humes 1957 was investigated under constant experimental conditions (19 20°C and 38‰ S). For each of the first six experiments, females (F1), whose life history was followed, were obtained from a common mother (F0). Experiment no 7 was carried out with adult females (F2) obtained during exp. 4. Females were bred in 50-ml dishes and transferred to a fresh container as soon as they produced a new egg-sac. Offspring (F2: exp. 1 6; F3: exp. 7) from successive egg-layings were counted as soon as they moulted into adults. Larval mortality was estimated by enumeration of the adults issuing from a known number of nauplii that had been fed different bacteria strains. Some difficulties arose in obtaining adults with NCMB 13: it appeared to be necessary to provide this first generation with a small quantity of TetraMin (commercial fish food) in order to initiate reproduction and obtain a second generation. However, in exp. 4, F2 adult females fed NCMB 13 became ovigerous and fertile without needing TetraMin. This result is interpreted as denoting an indispensable period of adaptation to the diet, which probably requires important changes at the enzymatic level. One experiment was carried out with Helgo 21; another one with NCMB 308; two with NCMB 13 (with a unique additional meal of TetraMin to allow reproduction), two with NCMB 13 during larval development, then only tetraMin during adult stage, and one with NCMB 13 alone (with females issued from exp. 4). Data obtained regarding longevity, duration of reproduction period, number of egg-sacs and number of adult descendants show an important variability between bacteria strains. Lower results were almost always obtained with Helgo 21 and NCMB 308. An interesting result lies in the maximum number of egg-sacs: low with Helgo 21 and NCMB 308 (5), but very ample with NCMB 13 (11 in one experiment). In experiment 7, carried out with animals bearing a large coefficient of inbreeding (0.375), the results concerning the maximum number of egg-sacs are good (10) as are the mean number of descendants per female (294: the highest number of the seven experiments). These results indicate that genetic factors involved in the reduction of descendants in ageing laboratory cultures can be suppressed to a certain extent by nutritional factors. The poor results obtained with Helgo 21 and NCMB 308 alone must be considered with caution: after a period of adaptation with an alimentary complement, these strains could perhaps permit an interesting production of copepods.

Antitumor and antifungal activities of organic extracts of seacucumber Holothuria atra from the southeast coast of India  

NASA Astrophysics Data System (ADS)

In phylum Echinodermata, the family Holothuridae is distinguished by its capacity of bioactive compounds. Sea cucumber Holothuria atra is commonly known as the lollyfish. The antifungal activity was detected using agar well diffusion method against the various fungal strains such as Trichoderma viride, Aspergillus niger, Aspergillus flavis, Candida albicans and Penicillium chrysogenum. Relatively high antifungal activity was seen against Candida albicans at 100 ?L-1 concentration of extracts. Zone of inhibition was measured at 18 mm of diameter. The anti-tumor activities were detected against the Vero and Hep2 cell lines using MTT assay. The cells were treated with H. atra extract at concentrations 0.078-10mg mL-1. The extract showed high proliferative activity against the Hep2 cells. The body wall extracts of sea cucumber ( H. atra) showed effective antifungal and antitumor activities. All these findings suggest that the extracts could be used for the development of drugs.

Structure elucidation, protein profile and the antitumor effect of the biological active substance extracted from sea cucumber Holothuria polii.  


Holothuria polii (Delle Chiaje, 1823) (Holothuriidae) is a sea cucumber inhabiting Mediterranean Sea coast of Egypt. The bioactive compound of its tegument has antifungal, antibacterial and antiparasitic effects. The present study aims to elucidate the structure of the bioactive material of H. polii for pharmacological and chemotaxonomic purposes. Furthermore, the study demonstrates its efficacy as a cytotoxic agents against two tumor cell lines HCT116 (colon adenocarcinoma cell line) and MCF7 (breast adenocarcinoma cell line). The biological active compound of the ethanol extract has been characterized by means of infrared (IR), proton-nuclear magnetic resonance ((1)H NMR), ultraviolet-visible (UV-Vis) and mass spectra. Protein profile was carried out using sodium dodecyl sulfate polyacrylamide gel electrophoresis. Cytotoxic activity was carried out according to sulforhodamine-B assay. IR, (1)H NMR, UV-Vis and mass spectra showed that the extracted bioactive material is a nonsulfated hexaosides called bivittoside. This glycoside is composed of aglycone and a glycosidic chain (carbohydrate chain) enclosed with six sugar units, including xylose, glucose, 3-O-methylglucose and quinovose. There were no traces of dissolved proteins. The preliminary cytotoxic assay of bivittoside exhibited significant cytotoxic activity against two types of cultured tumor cell lines of HCT116 and MCF7. The half-maximal inhibitory concentration was 17.4 µg/ml and 18 µg/ml for MCF7 and HCT116, respectively. Although H. polii belongs to the genus Holothuria, the lacking of sulfate group and the fact that it contains up to six monosaccharides make it different from this genus. The present study suggests separation of H. polii from its genus to a new one. On the other hand, results support the hypothesis that H. polii bioactive compound has an antitumor effect.

Identification of endocannabinoid system-modulating N-alkylamides from Heliopsis helianthoides var. scabra and Lepidium meyenii.  


The discovery of the interaction of plant-derived N-alkylamides (NAAs) and the mammalian endocannabinoid system (ECS) and the existence of a plant endogenous N-acylethanolamine signaling system have led to the re-evaluation of this group of compounds. Herein, the isolation of seven NAAs and the assessment of their effects on major protein targets in the ECS network are reported. Four NAAs, octadeca-2E,4E,8E,10Z,14Z-pentaene-12-ynoic acid isobutylamide (1), octadeca-2E,4E,8E,10Z,14Z-pentaene-12-ynoic acid 2'-methylbutylamide (2), hexadeca-2E,4E,9Z-triene-12,14-diynoic acid isobutylamide (3), and hexadeca-2E,4E,9,12-tetraenoic acid 2'-methylbutylamide (4), were identified from Heliopsis helianthoides var. scabra. Compounds 2-4 are new natural products, while 1 was isolated for the first time from this species. The previously described macamides, N-(3-methoxybenzyl)-(9Z,12Z,15Z)-octadecatrienamide (5), N-benzyl-(9Z,12Z,15Z)-octadecatrienamide (6), and N-benzyl-(9Z,12Z)-octadecadienamide (7), were isolated from Lepidium meyenii (Maca). N-Methylbutylamide 4 and N-benzylamide 7 showed submicromolar and selective binding affinities for the cannabinoid CB1 receptor (Ki values of 0.31 and 0.48 ?M, respectively). Notably, compound 7 also exhibited weak fatty acid amide hydrolase (FAAH) inhibition (IC50 = 4 ?M) and a potent inhibition of anandamide cellular uptake (IC50 = 0.67 ?M) that was stronger than the inhibition obtained with the controls OMDM-2 and UCM707. The pronounced ECS polypharmacology of compound 7 highlights the potential involvement of the arachidonoyl-mimicking 9Z,12Z double-bond system in the linoleoyl group for the overall cannabimimetic action of NAAs. This study provides additional strong evidence of the endocannabinoid substrate mimicking of plant-derived NAAs and uncovers a direct and indirect cannabimimetic action of the Peruvian Maca root.

Immune mediators of sea-cucumber Holothuria tubulosa (Echinodermata) as source of novel antimicrobial and anti-staphylococcal biofilm agents  

PubMed Central

The present study aims to investigate coelomocytes, immune mediators cells in the echinoderm Holothuria tubulosa, as an unusual source of antimicrobial and antibiofilm agents. The activity of the 5kDa peptide fraction of the cytosol from H. tubulosa coelomocytes (5-HCC) was tested against a reference group of Gram-negative and Gram-positive human pathogens. Minimal inhibitory concentrations (MICs) ranging from 125 to 500 mg/ml were determined against tested strains. The observed biological activity of 5-HCC could be due to two novel peptides, identified by capillary RP-HPLC/nESI-MS/MS, which present the common chemical-physical characteristics of antimicrobial peptides. Such peptides were chemically synthesized and their antimicrobial activity was tested. The synthetic peptides showed broad-spectrum activity at 12.5 mg/ml against the majority of the tested Gram-positive and Gram-negative strains, and they were also able to inhibit biofilm formation in a significant percentage at a concentration of 3.1 mg/ml against staphylococcal and Pseudomonas aeruginosa strains. The immune mediators in H. tubulosa are a source of novel antimicrobial peptides for the development of new agents against biofilm bacterial communities that are often intrinsically resistant to conventional antibiotics.

Effect of density on larval development and female productivity of Tisbe holothuriae (Copepoda, Harpacticoida) under laboratory conditions  

NASA Astrophysics Data System (ADS)

The harpacticoid copepod Tisbe holothuriae has been cultivated in the Helgoland laboratory for more than 20 years. The effects of density on the larval development and the female productivity were studied by comparing two culture systems: (1) enclosed system, and (2) running-water system. In both systems, a nutritious mixed diet of Dunaliella tertiolecta, Skeletonema costatum, and granulated Mytilus edulis was offered. Larval mortality, larval development and female productivity are found to be significantly dependent on both the population density and specificity of the culture system. Increasing density causes higher larval mortality, longer larval development time, and a reduction in female productivity. In comparison with the enclosed system, the running-water system shows decisive advantages: larval mortality is about 20% lower, the rate of larval development is about two days shorter, and there is a very high rate of nauplii production. The sex ratio exhibits high variations, but in general, there is no clear relationship between sex ratio and population density. Nevertheless, when reared in the running-water system, a relatively high percentage of females (>45%) was found at lower densities.

Protective and Curative Effects of the Sea Cucumber Holothuria atra Extract against DMBA-Induced Hepatorenal Diseases in Rats  

PubMed Central

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.

Acidic mucopolysaccharide from Holothuria leucospilota has antitumor effect by inhibiting angiogenesis and tumor cell invasion in vivo and in vitro.  


Acidic mucopolysaccharide from Holothuria Leucospilota (HS) may affect some steps in metastasis cascade. In vitro, HS inhibited the growth of B16F10 cells and proliferation of VEGF-induced HUVEC dose-dependently compared to the control, VEGF-induced capillary-like tube networks and the numbers of migratory and invasive cells were significantly inhibited by HS in a dose-dependent manner under the cytotoxic doses. Additionally, VEGF-induced vessel sprouting of rat aortic ring was also inhibited by HS. It also has been demonstrated that the invasive ability of B16F10 melanoma cells through the Matrigel-embedded Boyden chamber was suppressed by 0.5 muM HS. The protein level secreted by B16F10 cells of MMP-2,-9 and VEGF were decreased by HS treatment. In vivo, a tumor growth inhibition study was carried out using mice bearing B16F10 cells model of metastasis, no matter experimental or spontaneous, showed that HS at 5.2, 11.6 and 26 mg/kg (weight of mice) could markedly decreased the metastatic tumors in mouse lung in a dose-dependent manner. In CAM assay and Matrigel plug assay in vivo, HS (50 microg/egg and 100 microg/egg) inhibited new blood vessel formation on the growing chick chorioallantoic membrane, and HS (5.2 and 26 mg/kg body weight) reduced the vessel density in Matrigel plugs implanted in mice. Taken together, these results demonstrate that HS has antimetastasic properties possibly via its antiangiogenesis induced by downregulation of VEGF and suppression of invasive ability of cancer cells mediated by downregulation of MMP-2, -9 and their activities.

Putative mechanism for apoptosis-inducing properties of crude saponin isolated from sea cucumber (Holothuria leucospilota) as an antioxidant compound  

PubMed Central

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

Calbindin-D32k is localized to a subpopulation of neurons in the nervous system of the sea cucumber Holothuria glaberrima (Echinodermata).  


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.

Collective Enumeration  

PubMed Central

Many joint decisions in everyday life (e.g., Which bar is less crowded?) depend on approximate enumeration, but very little is known about the psychological characteristics of counting together. Here we systematically investigated collective approximate enumeration. Pairs of participants made individual and collective enumeration judgments in a 2-alternative forced-choice task and when in disagreement, they negotiated joint decisions via verbal communication and received feedback about accuracy at the end of each trial. The results showed that two people could collectively count better than either one alone, but not as well as expected by previous models of collective sensory decision making in more basic perceptual domains (e.g., luminance contrast). Moreover, such collective enumeration benefited from prior, noninteractive practice showing that social learning of how to combine shared information about enumeration required substantial individual experience. Finally, the collective context had a positive but transient impact on an individual's enumeration sensitivity. This transient social influence may be explained as a motivational factor arising from the fact that members of a collective must take responsibility for their individual decisions and face the consequences of their judgments.

Blood Collection  

NASA Technical Reports Server (NTRS)

The method that is used for the collection, storage and real-time analysis of blood and other bodily fluids has been licensed to DBCD, Inc. by NASA. The result of this patent licensing agreement has been the development of a commercial product that can provide serum or plasma from whole blood volumes of 20 microliters to 4 milliliters. The device has a fibrous filter with a pore size of less than about 3 microns, and is coated with a mixture of mannitol and plasma fraction protein. The coating causes the cellular fraction to be trapped by the small pores, leaving the cellular fraction intact on the fibrous filter while the acellular fraction passes through the filter for collection in unaltered form from the serum sample collection chamber. The method used by this product is useful to NASA for blood analysis on manned space missions.

Collective Electrodynamics  

NASA Astrophysics Data System (ADS)

In this book Carver Mead offers a radically new approach to the standard problems of electromagnetic theory. Motivated by the belief that the goal of scientific research should be the simplification and unification of knowledge, he describes a new way of doing electrodynamics--collective electrodynamics--that does not rely on Maxwell's equations, but rather uses the quantum nature of matter as its sole basis. Collective electrodynamics is a way of looking at how electrons interact, based on experiments that tell us about the electrons directly. (As Mead points out, Maxwell had no access to these experiments.) The results Mead derives for standard electromagnetic problems are identical to those found in any text. Collective electrodynamics reveals, however, that quantities that we usually think of as being very different are, in fact, the same--that electromagnetic phenomena are simple and direct manifestations of quantum phenomena. Mead views his approach as a first step toward reformulating quantum concepts in a clear and comprehensible manner. The book is divided into five sections: magnetic interaction of steady currents, propagating waves, electromagnetic energy, radiation in free space, and electromagnetic interaction of atoms. In an engaging preface, Mead tells how his approach to electromagnetic theory was inspired by his interaction with Richard Feynman. Carver A. Mead is the Gordon and Betty Moore Professor of Engineering and Applied Science, Emeritus, at the California Institute of Technology. He won the 1999 Lemelson-MIT Prize for Invention and Innovation.

Pamphlet Collection  

NSDL National Science Digital Library

In a welcome move to researchers and historians, the British Library of Political and Economic Science (BLPES) has created an online guide to its large pamphlet collection, containing some 90,000 pamphlets, many from the 19th and early 20th centuries. While covering a number of important public and political issues in British history, the collection also contains a fair amount of European and International materials, including a large number of German-language pamphlets, as well as materials on Latin American trade unions, the League of Nations, pacifism, the two World Wars, and conflict in the Middle East. Users can browse the guide by fifteen topics (e.g., Issues in British history, political parties, social policy, poor laws, transport, etc.) or search the online catalog by subject keyword, author, title, or issuing body. The guide lists pamphlet author, title, and classmark, while the online catalog also includes publisher, pages, location, and other notes. As an added bonus, the majority of pamphlets listed in the social policy and transport guides have been digitized and are available in .pdf format.


Hemingway Collection  

NSDL National Science Digital Library

Ernest Hemingway was a red-blooded man of letters, and one of the 20th century's most celebrated and demonized writers. In 1968, Mary Hemingway arranged to have his papers donated to the Kennedy Library. Over the past several decades, materials related to Hemingway's long career have continued to become part of this very extensive collection. The Kennedy Library has created this specific page to provide both researchers and members of the general public with some basic information about their holdings, along with offering access to a selection of these papers. The photograph galleries are a real treat, as they cover everything from Hemingway's youth in Oak Park all the way up to his last days in Idaho.


Active Operations on Collections  

Microsoft Academic Search

Collections are omnipresent within models: collections of ref- erences can represent relations between objects, and collections of values can represent object attributes. Consequently, manipulating models often consists of performing operations on collections. For example, transfor- mations create target collections from given source collections. Similarly, constraint evaluations perform computation on collections. Recent re- search works focus on making such transformations or

Value, Market Preferences and Trade of Beche-De-Mer from Pacific Island Sea Cucumbers  

PubMed Central

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.

Seawater sampling and collection.  


This video documents methods for collecting coastal marine water samples and processing them for various downstream applications including biomass concentration. nucleic acid purification, cell abundance, nutrient and trace gas analyses. For today's demonstration samples were collected from the deck of the HMS John Strickland operating in Saanich Inlet. An A-frame derrick, with a multi-purpose winch and cable system, is used in combination with Niskin or Go-Flo water sampling bottles. A Conductivity, Temperature, and Depth (CTD) sensor is also be used to sample the underlying water mass. To minimize outgassing, trace gas samples are collected first. Then, nutrients, chemistry, and cell counts are determined. Finally, waters are collected for biomass filtration. The set-up and collection time for a single cast is approximately 1.5 hours at a maximum depth of 215 meters. Therefore, a total of 6 hours is generally needed to complete the four-part collection series described here. PMID:19536065

Collective Phase Sensitivity  

E-print Network

The collective phase response to a macroscopic external perturbation of a population of interacting nonlinear elements exhibiting collective oscillations is formulated for the case of globally-coupled oscillators. The macroscopic phase sensitivity is derived from the microscopic phase sensitivity of the constituent oscillators by a two-step phase reduction. We apply this result to quantify the stability of the macroscopic common-noise induced synchronization of two uncoupled populations of oscillators undergoing coherent collective oscillations.

Fashion Plate Collection  

NSDL National Science Digital Library

There are fashion plates, and then there are the exquisite fashion plates that constitute the University of Washington Libraries digitized collection. The plates were first collected by long-time home economics professor Blanche Payne, who taught at the University from 1927 to 1966. The plates come from leading French, American, and British fashion journals of the 19th and early 20th century and they document many stylistic periods, such as the Empire, Romantic, Victorian, and Edwardian. Visitors will want to start by reading an essay on the collection, and then they should feel welcome to browse the collection of over 400 plates at their leisure, or to browse the collection by subject. One fascinating aspect of the site is an extended excerpt from the 1913 book "Dame fashion" which comments on the history and transformation of various fashions during the 19th century.

Debt collection project report  

SciTech Connect

In October 1979 the Office of Management and Budget initiated a review of debt collection within the Federal Government. A DOE Debt Collection Project Team was established, and seven activites were selected for review. These were Albuquerque Operations Office; Bonneville Power Administration; Chicago Operations and Regional Office; Naval Petroleum Reserves, California; Oak Ridge Operations Office; Washington Financial Services Division; and Western Area Power Administration. The team visited each of these activities to collect data on the size, age, and types of receivables managed and procedures for billing, aging, and handling overdue accounts. Various deficiencies were found to exist at several of the DOE entities that are not consistent with good management practices in the performance of their debt collection functions. Also, the Debt Collection Project Team identified a wide variation in the procedures followed by DOE activities in the management of accounts receivable, and a wide variation in the effectiveness of the debt management functions. 1 figure, 17 tables.

UWM Book Arts Collection  

NSDL National Science Digital Library

Here's a chance to get a look at 31 artists' books, in digital form, without having to make a trip to the Special Collections Department at University of Wisconsin-Milwaukee. Included in the collection are exampled of many different book and paper arts techniques, such as papermaking, different styles of hand-binding, and page design. 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."

A Survey of Collectives  

NASA Technical Reports Server (NTRS)

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.

Theory of Collective Intelligence  

NASA Technical Reports Server (NTRS)

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.

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


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

The Arts Collection  

NSDL National Science Digital Library

A growing collection currently developing at the University of Wisconsin-Madison, the Arts Collection intends to bring together "in digital form, primary and secondary materials relating to the creative arts as broadly defined: visual, literary, musical, and performing." The first components of the collection are a journal Arts in Society, published at University of Wisconsin from 1958 to 1976, and the exhibition catalog from a show of photographs by Lewis Koch, "Notes from the Stone-paved Path: Meditations on North India", exhibited at UW-Madison in 2003. The catalog was a little cantankerous viewed with Safari on MAC OSX, but includes over a dozen high quality black-and-white photographs by Koch, paired with books and poetry from the UW-Madison Libraries Special Collections. The full text of 41 issues of Arts in Society is available; the journal primarily published themed issues, such as Volume 5, Issue 1 (1968) happenings and intermedia, which kicks off with an introduction by editor Edward L. Kamarck entitled "Intermedia is a better name than happenings: what we had in mind in putting together this issue".

Those with interest in conducting further research may find the Guide to Maryland Maps link useful, as it provides an overview of the non-digitized portion of the collection.



Lincoln Park Neighborhood Collection  

NSDL National Science Digital Library

Today, the Lincoln Park neighborhood on Chicago's North Side is a relatively affluent area, complete with Victorian mansions and rather tony elevator apartment buildings. By the late 1940s, the area was experiencing the same type of urban disinvestment as other inner-city neighborhoods throughout the United States. In the early 1960s, the city of Chicago, working with funds from the federal government, began an ambitious urban renewal program designed to reduce the density of the built environment in the community and to remove "blighted" properties. This excellent collection from the DePaul University Libraries Digital Collections contains over 400 documents related to this ambitious project, including maps, zoning documents, policy statements, neighborhood organization planning documents, and photographs. First-time visitors may wish to start with the first document here, "A Brief Explanation of the Urban Community Conservation Act." Moving on, visitors can view the rest of the documents by title, thumbnail, subject, and brief description.


Daphne Dare Collection  

NSDL National Science Digital Library

Daphne Dare worked behind the scenes, but her work was always on stage. Dare was a British costume designer for plays, movies, and TV and was involved in more than 60 productions. She even designed costumes and monsters for the first two years of Dr. Who. The Ohio Digital Resource Commons hosts the digitized collection of over 1100 images of Dare's costumes and set designs. Visitors should read the introduction about Dare on the homepage to see the depth and breadth of her work, which spanned from the late 1950s to the mid 1990s. At the bottom of the homepage, visitors should click on "See all records" to browse the collection. The browsing feature at the top of the page allows for visitors to view the entries by "Titles" "Issue Date" or "Series". Visitors should not miss the drawing "Costume and Set Design for Zorba: 'Men'" which looks like an artwork in itself.


Temple Sheet Music Collections  

NSDL National Science Digital Library

Over the past few years, more and more university libraries have worked diligently to digitize some of their vast sheet music holdings. Old chestnuts are being revived by vocal groups on campus and farther afield, which is certainly a good thing. This sheet music collection from the Temple University Libraries brings together 850 pieces of music for consideration by the general public. Visitors can search the collection as they see fit. They will find that most of the music here is from the Gilded Age and earlier. There are a number of melodic tunes in here; visitors might do well to consider "Drifting Leaves" from 1905 or 1852's "Dreams of Home" as a way to get started on their journey. The site will be of great interest to musicologists and to anyone with an interest in the history of American popular song and musical heritage.



Cornell Modern Indonesia Collection  

NSDL National Science Digital Library

In 1956, the Cornell Modern Indonesia Project (CMIP) published its first title. Since then, the modern nation of Indonesia has seen numerous transformations and this digital collection houses works published by the CMIP, which document these changes. Early on, the first documents created were called "Interim Reports", and they dealt with the 1965 coup, foreign policy, and the state of Chinese citizens in Indonesia. The monographs in the collection focus primarily on Indonesian politics, but they also include anthropological and social analyses as well. Currently, there are over four dozens titles here, and visitors can browse them by title or author. One item that should not be missed is the 1965 update of the 1936 study "Mythology and the tolerance of the Javanese". Southeast Asian scholars and those with an interest in the history of this region will not be disappointed.


Beloit College: Bartlett Collection  

NSDL National Science Digital Library

Professor Harley Harris Bartlett taught botany at the University of Michigan for many decades and he also served as the director of the university's botanical gardens. During his botanical research trips to Asia he brought back diverse collections of ethnographic material. After he passed away in 1960, his sister donated over 300 objects from Indonesia, Taiwan, and the Philippines to the Logan Museum at Beloit College. The items here include carved figures, manuscripts, textiles, and other cultural artifacts. Visitors can browse within the collection as they see fit and they may wish to start by looking at the remarkable animal figurines and armbands. It's a wonderful resource for people with a penchant for the world of material culture in Southeast Asia.


Cornell Modern Indonesia Collection  

NSDL National Science Digital Library

In the 1950s, a group of scholars in Cornell University's Southeast Asia Program initiated the Cornell Modern Indonesia Project (CMIP). The intent of the program was to make contemporary analyses of Indonesia available to scholars and students. The titles were digitized by the Cornell University Library, and this marvelous collection represents the fruits of their endeavors and captures "the drama of Indonesia's political and social evolution through the twentieth century." Some of the topics covered include the development of Indonesian civil government, their civil insurgencies, and the Japanese Occupation. Visitors can search the collection, or they can also browse through the offerings here, which are arranged by author name and title. Visitors who are finding themselves a bit lost should also feel free to click on the "Help" section for hints on searching through the site and viewing and navigating these documents.


Pennell Photography Collection  

NSDL National Science Digital Library

Joseph J. Pennell was a successful commercial studio photographer who worked in Junction City, Kansas from the early 1890s to the early 1920s. During his long tenure in this quaint burg he managed to document all facets of town life. Through portraits of local celebrities, prominent families, soldiers, and photos of local businesses the culture of this town at the turn of the century was preserved. This digital collection from the University of Kansas brings together almost 6000 images culled from his many years in the community. Visitors can browse around at their leisure or they can also use the Browse by Categories area to look around by subject. Interesting topics include architecture, boxing, street scenes, and Thanksgiving. The zoom feature is especially worth noting as it allows for a rather life-like examination of the collection. All in all, it's a remarkable archive and one that will warrant several return visits.


Evanion Collection of Ephemera  

NSDL National Science Digital Library

Illusionist and conjurer Henry Evans, or "Evanion" (his stage name), was quite a force to be reckoned with in the second half of the 19th century. During his long career, he used his theatrical experience to collect a vast amount of printed ephemera related to entertainment and everyday life in Victorian England. Evan's collection was purchased by the British Museum in 1895, and recently the Museum has created this online trove of over 2000 items from the original 5000 or so pieces. The items include trade cards, shop catalogues, restaurant menus, and handbills. First-time visitors can check out the "Curator's Choice" area, which contains favorite items as selected by Museum curator Helen Peden. Her favorites include a trade card created to promote the work of pyrotechnist James Pain and an advertisement for cocoa products. Finally, visitors are encouraged to use the search engine to look for items of particular interest.


Collective network routing  


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.

Leslie Jones Collection  

NSDL National Science Digital Library

During a long career, Leslie Jones (a self-described "camera-man") took well over 40,000 photographs documenting the city of Boston and environs. Jones was a staff photographer for the Boston Herald-Traveler from 1917 to 1956, and he covered everything from a fox stuck in a tree on the Boston Common to Charles Lindbergh's U.S. tour after his historic crossing of the Atlantic. This remarkable online collection of photos was created by the Boston Public Library from the images generously donated by Jones' family. The photos are divided into over five dozen topical collections, including "Animals: Birds," "Boston: Neighborhoods," "Boston: Waterfront," and "Maritime: USS Constitution." Also of note are several particularly unique groupings dedicated to fires and fire departments around the city and the state of Massachusetts.

Jones, Leslie, 1886-1967

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.

Transportation Library Menu Collection  

NSDL National Science Digital Library

To fly the friendly skies in the 1950s and 1960s across the continent (or the Atlantic) was quite an experience. To say nothing of the possible turbulence, the culinary offerings in flight could be quite outstanding. The late George M. Foster (an anthropologist and consultant) was there at the beginning of such pioneering commercial air travel. He collected hundreds of menus from his time on trains, planes, and cruise ships, and he gave them to Northwestern University in 1997. This digital collection from the Northwestern University Library allows users to look at these items in all of their glorious detail. After clicking on "View the Contents" visitors can make their way through menus from Air Canada, Cathay Pacific, United Airlines, and so on. First-time visitors should not miss the menu from a Chicago to Amsterdam flight on KLM that Mr. Foster took on June 21, 1979. Finally, visitors should also read the letter that Mr. Foster wrote about the collection shortly before he passed away in 2006.



Polish Declarations Collection  

NSDL National Science Digital Library

The relationship between Poland and the United States has existed for several centuries, as early as the Revolutionary War some of the key figures were great Polish military heroes, such as Casimir Pulaski and Tadeusz Kosciuszko. Continuing and strengthening the relationship between these two countries over the years are the many Poles who have immigrated to the United States. Recently, the Library of Congress digitized one of the most interesting (and little-known) documents in their collection, the Polish Declarations of Admiration and Friendship for the United States. The 111-volume collection was given to President Calvin Coolidge in 1926 to commemorate the 150th anniversary of US independence. These ornately decorated volumes were signed over an eight-month period by nearly one-sixth of Poland's population in 1926, totaling close to 5.5 million signatures. The Library of Congress has digitized the first eleven volumes, and placed them online here for consideration by genealogists, historians, and other interested parties. The first several volumes contain the signatures of government officials, artists (including full-size works of art), and signatures from three institutions of higher learning. Visitors can search the contents by keyword, geographic locations, and by title. Overall, this is a rather remarkable collection, and one that will merit several visits.



Mary Louise Reynolds Collection  

NSDL National Science Digital Library

Mary Louise Reynolds (1891-1950) led a fascinating life at the center of the Surrealist circle of artists, numbering as her friends Max Ernst, Man Ray, Paul �luard, André Breton, Jean Cocteau, and Salvador Dalí. Reynolds and Surrealist Marcel Duchamp were partners in a long term relationship thought by their friends to be far happier than most marriages. She was a book artist and served in the French resistance during World War II. The materials in the Mary Louise Reynolds Archive and her collection of rare books and bindings at the Art Institute of Chicago have inspired at least two books and several exhibitions, as well as this Web site. The site features four essays reprinted from the Art Institute's Museum Studies journal, illustrated with digital images of Surrealist works, and available in both HTML and Adobe Acrobat (.pdf) formats. There is also an online finding aid to the collection, and it is possible to search the Ryerson and Burnham Library's catalog for Reynolds collection items. One portion of the site (View Works of Art) brings together all the digitized works of art: Reynolds' book bindings, Surrealist documents, prints, and a few photographs.


The Leonard Bernstein Collection  

NSDL National Science Digital Library

The online Leonard Bernstein Collection that is part of the Library of Congress American Memory project is rich with a variety of media, including: "Professor Lenny", an essay about Bernstein from the New York Review of Books; many endearing photographs; over 1,100 pieces of correspondence to and from family, friends, and colleagues; 177 scripts from his "Young People's Concerts"; and a timeline of his life from 1918-1990 which records his musical career, as well as his personal life. In order to assist visitors with all of this wonderful material, a helpful finding aid for the collection is also provided. Click on the "About This Collection" section on the left side of the page, to quickly find the links to the above-mentioned sections. The visitor should not miss looking at some of the photos from the "Gallery" area. Many of the photos are divided up into one to three year sections, and some are divided up by decade, making it a very manageable gallery. Under the "1955-1957" tab you will find some wonderful photos of Bernstein's wife and young children, Jamie and Alexander. The gallery is filled with images of him with his family, many of which had been made into holiday cards.


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.


Collective Intelligence. Chapter 17  

NASA Technical Reports Server (NTRS)

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.

Portable liquid collection electrostatic precipitator  


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.

Kraith Collected Issue 5  

E-print Network

", the first of the Kraith Spinoff stories to be published in Kraith Collected since the Doris Beetam vignettes in volume one. I enjoyed "Servant of the People" very much, and I feel it is very close to Kraith. However, the portrayal of the UFP bureaucracy... is such that the story feels to me more like a parody of bureaucracy than an attempt to portray the UFP of the Kraith universe in all seriousness. "Servant of the People" is a good story, and it wouldn't be right to leave it out. But we can't lock all the Kraith...

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.


Bowen Country Club Collection  

NSDL National Science Digital Library

One of the ambitions of service groups like Chicago's Hull House was to provide urban youth with an opportunity to get out and experience some clean fresh air. The Hull House on Chicago's Near West Side took children from the surrounding neighborhood out to the Joseph T. Bowen Country Club every year from 1912 until 1963. The Club was financed by social activist and philanthropist Louise deKoven Bowen, and was located on 72 hilly and forested acres near Waukegan, Illinois. Young people from the city would come out to the grounds in two-week shifts and take part in team sports contests, learn how to dance, and also take art lessons. This wonderful photo collection from the Special Collections Department of the University of Illinois at Chicago's library presents over 480 images of life at the club. Visitors to the site will find images of camp activities, the grounds, social life, and the broader milieu of the place. It's quite a find and one that will be of interest to persons with an interest in Chicago history and the history of outdoor recreation.

Lauren R. Donaldson Collection  

NSDL National Science Digital Library

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.

As a secular saint of Tin Pan Alley, Hoagy Carmichael looms large in the world of American popular song. As a native Hoosier, Carmichael graduated from the Indiana University School of Law and went on to write hundreds of standards, including "Star Dust" and "Two Sleepy People". This digital tribute and archive to his work was created by staff members at the Indiana University Library. On the site's homepage, visitors can read a brief introduction about Carmichael and the digitization project. Next, the "Browse" section will give visitors access to photographs, correspondence, typescripts, publicity, and personal effects from the collection. The "Lyric Sheets" area shouldn't be missed as visitors can look at the music for "Always", "Air pollution blues", and several hundred other ditties. The "Photographs" area includes portraits of Carmichael as a young man and during his time on the Movie Time USA tour in the 1940s. Additionally, visitors can get help with research about Carmichael and also perform a more detailed search across the entire collection.

Solar energy collection system  

NASA Technical Reports Server (NTRS)

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.

The Bentley Collection  

NSDL National Science Digital Library

Wilson Alwyn Bentley (1865-1931), famous for his photomicrographs of snow crystals, prepared sets of glass lantern slides of dew, frost and ice crystals. He obtained thousands of photomicrographs of individual ice crystals over the course of his lifetime. Images in this collection are scanned from glass lantern slides. Most snow crystals found in nature will fit into one of these seven main categories: plates, stellar crystals, columns, needles, spatial dendrites, capped columns, and irregular forms. Because there are many variations within these categories which are not separately identified by the International Snow Classification the Bentley project uses the Magono and Lee (1966) snow crystal classification scheme. Each crystal is classified and searchable according to this scheme.



Terrorism and Security Collection  

NSDL National Science Digital Library

The National Academies Press (NAP) offers the full text of several publications related to bioterrorism, laboratory safety, and cryptography, among other topics, for browsing online.

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.


Tech News Collection  

NSDL National Science Digital Library

The Illinois Institute of Technology (IIT) started life in 1893 as the Armour Institute, courtesy of funding from Philip Danforth, Sr. who gave $1 million to start a school that would offer courses in engineering, chemistry, architecture, and library science. In 1940, the school merged with the Lewis Institute and received its current name. This intriguing digital collection offers a look into the school's history via the Technology News, which has been the student newspaper since 1928. Visitors can browse past issues from that year up to the current day. The Features area is quite interesting, as it includes direct links to April Fools issues and topical coverage of swine flu outbreaks in 1976 and 2009. The April Fools issue from 1942 is quite a pip, as it includes articles titled "Surrealist Ginks Gab" and "Tennis Toddlers Tersely Terrorize Tirty-Tird Toughs."



Century 21 Digital Collection  

NSDL National Science Digital Library

From April 21 to October 21, 1962, Seattle played host to millions of people who sought out a glimpse into the future through the Century 21 Exposition. This world's fair presented an optimistic vision of "a future improved through science and technology" and this online collection from the Seattle Public Library presents over 1,200 photographs of the fair, along with books, brochures, reports, and more. The photos were taken by Werner Lenggenhager, a Swiss immigrant who donated his works to the Seattle Public Library after his death. Visitors can browse the suggested topics, which include Aerial Views, Space Needle, and Seattle Center Before Century 21. Visitors should also be sure to catch the six photos of Elvis Presley as he sang and danced his way across the grounds while filming, "It Happened at the World's Fair."


Herman Miller Consortium Collection  

NSDL National Science Digital Library

The well-known firm of Herman Miller began manufacturing residential furniture in 1923. Based in Zeeland, Michigan, the company has created everything from the marshmallow sofa to the molded plywood chair. Also, it has played host to designers like Charles and Ray Eames and George Nelson. This rather nice digital collection from The Henry Ford Museum brings together over 366 images of various works created over the past eight decades. The materials are drawn from the Herman Miller Consortium, which was established in 1988 to bring together significant items from the company's corporate archives. Visitors can use the Browse all media link to look around at their leisure. It's a great way to learn about many key innovators in American furniture design throughout much of the 20th century.

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.


Douglas Menuez Photography Collection  

NSDL National Science Digital Library

Douglas Menuez began his careers as an intern with the Washington Post, and over the past several decades he has covered the AIDS crisis, the destruction of the Amazonian rainforest, and a host of other topics. One of his projects included documenting the rise of Silicon Valley, and along the way he took some 250,000 photographs that together constitute an insider's look at the world of venture capital, the semiconductor industry, and of course, the heady early days of the Internet's exponential growth. Recently, Stanford University acquired this prodigious collection. Visitors to this site can browse through approximately 2900 of these photographs, and given the number of images, this site certainly warrants several visits.


Tupper Scrapbook Collection  

NSDL National Science Digital Library

William Vaughn Tupper was quite the traveler, wandering around Europe, Great Britain, and North Africa from 1891-1894 with his family. 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.


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.


Indianapolis Postcard Collection  

NSDL National Science Digital Library

Since the copyright for the postcard was first issued in 1861, people have found that the "small, thin postcard is a quick and inexpensive way to keep in touch with others." Hoosiers love postcards just as much as anyone, and this delightful collection from the Indianapolis Public Library brings the magic of the postcard alive. Here, visitors can look over 500 postcards depicting scenes from around the Circle City and elsewhere. The curious guest can look over cards featuring poetry from James Whitcomb Riley, the Emrichsville Bridge over the White River, and much more. Visitors shouldn't miss the wonderful images of the World War Memorial, Riverside Boulevard, and a host of images related to various cultural institutions downtown.


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.


Old Boston Photograph Collection  

NSDL National Science Digital Library

In 2007, the Boston Public Library rediscovered a rather intriguing cache of photographs from the late 19th century in their archives. While there is still some debate about the provenance of these photos, they believe that the prints were taken by photographers affiliated with the Boston Camera Club, and that this organization was responsible for coordinating this specific project. Recently, the Library decided to digitize 113 of these images, and they are available here. Visitors can search the collection by keyword, and they will also find that the Flickr format will all allow them to send images to friends and also zoom in for a closer look. There are some great items here, including a print of Benjamin Franklin's house on Milk Street and a photograph of the Old State House from 1898.

Some of the titles of the activities include The Discovery Of Radioactivity: The Dawn of the Nuclear Age; Radioactivity: Historical Figures; How We See: The First Steps of Human Vision; Discovery, Chance, and the Scientific Method; DNA Structure; and Development of Polio Vaccines. The pages and activities are well designed and offer educators some interesting and unique lessons for their students.


Clement Moran Photography Collection  

NSDL National Science Digital Library

Clement Moran became fascinated with photographs as a young man, though he came to New Hampshire College (now the University of New Hampshire) in 1914 to teach physics. Over a period of 70 years, he documented the changes around the campus in Durham, and also served as the institution's first official university photographer. His massive archive is housed at the university's library and this digital collection affords interested parties access to over 900 of these remarkable images. Visitors can browse through the images by date or category, but the images of the campus are the real highlights here. The archive contains wonderful photos of the 1917 football team, the university wood shop as it appeared in 1916, and the Delta Sigma Chi "Ski Jumper" snow sculpture from 1931. It's a nice slice of New England history and a wonderful way to learn about the school's history.

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.


WTO Seattle Collection  

NSDL National Science Digital Library

Few were prepared for the events of November 30th, 1999 in the usually peaceable town of Seattle. As the World Trade Organization (WTO) began its opening conference ceremonies, protestors began to coalesce around the doors of the Washington State Convention Center. The protestors were there to protest many of the actions of the WTO, and by the end of the day this situation was quite chaotic as the Seattle Police Department ran low on tear gas and Seattle Mayor Paul Schell declared a state of emergency. The protest received wide national and international coverage, and this digital collection from the University of Washington brings together some of the ephemeral printed material that was generated around the time of the demonstrations. Users can perform a keyword search on the database, or they can search the materials by category headings, which include "photographs", "planning documents", and "environment". For students of international protest movements, social action, and other related matters, this site will be quite interesting.


Gesammelte Werke / Collected Works  

NASA Astrophysics Data System (ADS)

Der bekannte Astronom Karl Schwarzschild (1873-1916) gilt als der Begründer der Astrophysik und als hervorragender Forscher mit einer erstaunlichen Bandbreite seiner Interessen. Arbeiten zur Himmelsmechanik, Elektrodynamik und Relativitätstheorie weisen ihn als vorzüglichen Mathematiker und Physiker auf der Höhe seiner Zeit aus. Untersuchungen zur Photographischen Photometrie, Optik und Spektroskopie zeigen den versierten Beobachter, der sein Meßinstrumentarium beherrscht, und schließlich arbeitete Schwarzschild als Astrophysiker an Sternatmosphären, Kometen, Struktur und Dynamik von Sternsystemen. Die in seinem kurzen Leben entstandene Fülle an wissenschaftlichen Arbeiten ist in drei Bänden der Gesamtausgabe gesammelt, ergänzt durch biographisches Material, Annotationen von Fachleuten und einen Essay des Nobelpreisträgers S. Chandrasekhar. The well-known astronomer Karl Schwarzschild (1873-1916) is regarded as the founder of astrophysics and as an exceptionally talented researcher whose interests spanned a remarkably broad spectrum. His work on celestial mechanics, electrodynamics, and relativity theory demonstrates his great abilities as a mathematician and physicist who significantly influenced the science of his times. His investigations of photographic photometry, optics, and spectroscopy display his strengths as an observer who knew his instruments. But above all Schwarzschild pursued questions of astrophysics, addressing in particular stellar atmospheres, comets, and the structure and dynamics of stellar systems. The host of scientific works that he authored in his short life is now collected in the form of this three-volume complete works; it is supplemented by biographical material, notes from some of todays experts, and an essay by the Nobel Laureate S. Chandrasekhar.

Lewis Hine Collection  

NSDL National Science Digital Library

Born in Oshkosh, Wisconsin in 1874, Lewis Hine studied at the University of Chicago and went on to teach at the Ethical Culture School in New York City. While in New York Hine took up photography and documented school activities and immigrants arriving at Ellis Island. He also became interested in taking photographs that would document child labor, and his photographs were published in the social welfare magazine "Charities and the Commons". As part of this work, he travelled from Texas to Maine to take photos of children working on the street, mills, and farms. These documents were instrumental in providing reform groups with the visual evidence of the negative impact that work had on children. The University of Maryland, Baltimore County has digitized 4,735 of these photographs and placed them here for the general public. Visitors can browse around the images by state, or they can also perform their own detailed search. It is a moving and compelling collection, and one that warrants several return visits.


Iowa Maps Digital Collection  

NSDL National Science Digital Library

Lovers of all things historical, a number of us at the Scout Report could not get enough of the Iowa Maps Digital Collection. As the second-most shared resource this past year, itâ??s clear that our readers enjoyed it too! The Iowa Digital Library allows interested parties to whiz through years of Iowa history, even providing a clickable map of specific counties. The site impressed us with its varied archive of cartography and clear browsing parameters, as well as the option allowing users to download or print the maps at home.The Iowa Digital Library has done the cartographically inclined a great service by digitizing hundreds of maps from the Hawkeye State's grand and glorious past. On the homepage, visitors will be treated to a moveable feast of maps, including one of Scott County from 1875, a stylized map of the University of Iowa campus from 1943, and an official railroad commissioners map of the state from 1915. Visitors can browse the maps by state, county, township, town, or country via a series of drop-down menus. Additionally, visitors can browse all of the maps by time period, advertisements, publisher, or contributing institution. Persons with an interest in the history of cartography, United States history, or other related subjects will want to make multiple visits to this site.



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.


Waste collection subsystem study  

NASA Technical Reports Server (NTRS)

Practical ways were explored of improving waste compaction and of providing rapid turnaround between flights at essentially no cost for the space shuttle waste collection subsystem commode. Because of the possible application of a fully developed shuttle commode to the space station, means of providing waste treatment without overboard venting were also considered. Three basic schemes for compaction and rapid turnaround, each fully capable of meeting the objectives, were explored in sufficient depth to bring out the characteristic advantages and disadvantages of each. Tradeoff comparisons were very close between leading contenders and efforts were made to refine the design concepts sufficiently to justify a selection. The concept selected makes use of a sealed canister containing wastes that have been forcibly compacted, which is removable in flight. No selection was made between three superior non-venting treatment methods owing to the need for experimental evaluations of the processes involved. A system requirements definition document has been prepared to define the task for a test embodiment of the selected concept.



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).


Physician collective bargaining.  


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.

Symmetries in collective neutrino oscillations  

E-print Network

We discuss the relationship between a symmetry in the neutrino flavour evolution equations and neutrino flavour oscillations in the collective precession mode. This collective precession mode can give rise to spectral swaps (splits) when conditions can be approximated as homogeneous and isotropic. Multi-angle numerical simulations of supernova neutrino flavour transformation show that when this approximation breaks down, non-collective neutrino oscillation modes decohere kinematically, but the collective precession mode still is expected to stand out. We provide a criterion for significant flavour transformation to occur if neutrinos participate in a collective precession mode. This criterion can be used to understand the suppression of collective neutrino oscillations in anisotropic environments in the presence of a high matter density. This criterion is also useful in understanding the breakdown of the collective precession mode when neutrino densities are small.

Tritium monitor and collection system  


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.

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.

Modelling fuel consumption in kerbside source segregated food waste collection: separate collection and co-collection.  


Source separated food waste is a valuable feedstock for renewable energy production through anaerobic digestion, and a variety of collection schemes for this material have recently been introduced. The aim of this study was to identify options that maximize collection efficiency and reduce fuel consumption as part of the overall energy balance. A mechanistic model was developed to calculate the fuel consumption of kerbside collection of source segregated food waste, co-mingled dry recyclables and residual waste. A hypothetical city of 20,000 households was considered and nine scenarios were tested with different combinations of collection frequencies, vehicle types and waste types. The results showed that the potential fuel savings from weekly and fortnightly co-collection of household waste range from 7.4% to 22.4% and 1.8% to 26.6%, respectively, when compared to separate collection. A compartmentalized vehicle split 30:70 always performed better than one with two compartments of equal size. Weekly food waste collection with alternate weekly collection of the recyclables and residual waste by two-compartment collection vehicles was the best option to reduce the overall fuel consumption.

Die Physikalische Sammlung (Physical Collection)  

E-print Network

At the end of the 17th century, the collection was established through the acquisition of Leiden instrumentmaker Musschenbroek's collection. Its aim was to demonstrate physical phenomena. Until the end of the 18th century, the collection was used and extended by a number of professors from various university departments in teaching mechanics, hydrostatics, optics and electrostatics. The foundation of the Institute for Mathematics and Physics in 1817 and the appointment of Christian Ludwig Gerling to the position of Professor for Mathematics, Physics and Astronomy strengthened the subject considerably. Gerling extended the collection mainly with devices for geodesy and astronomy, with more instruments being added in the time up to the middle of the 20th century. Today, the collection allows an insight into the history of scientific instruments as witnesses of the past.

Leadership, collective personality, and performance.  


By viewing behavior regularities at the individual and collective level as functionally isomorphic, a referent-shift compositional model for the Big 5 personality dimensions is developed. On the basis of this compositional model, a common measure of Big 5 personality at the individual level is applied to the collective as a whole. Within this framework, it is also hypothesized that leadership (i.e., transformational, transactional, and passive) would predict collective personality and that collective personality would be significantly related to collective performance. The results supported these hypotheses using a sample of franchised units. On the basis of recent research at the individual level, several interactions among the various personality dimensions were hypothesized and supported. Implications are discussed. PMID:15910146

The Ecology of Collective Behavior  

PubMed Central

Similar patterns of interaction, such as network motifs and feedback loops, are used in many natural collective processes, probably because they have evolved independently under similar pressures. Here I consider how three environmental constraints may shape the evolution of collective behavior: the patchiness of resources, the operating costs of maintaining the interaction network that produces collective behavior, and the threat of rupture of the network. The ants are a large and successful taxon that have evolved in very diverse environments. Examples from ants provide a starting point for examining more generally the fit between the particular pattern of interaction that regulates activity, and the environment in which it functions.

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.

Collective states and symmetry rearrangement  

SciTech Connect

Collective states provide an important feature of the low-lying excitations in nuclei. Very often these states are inter-mingled with single particle excitations and surface vibrations of the finite nuclei. Here the authors wish to explore the collective states from the general viewpoint of symmetry rearrangement which has been studied extensively by Prof. Umezawa and his collaborators who showed, in a brilliant way, how the Goldstone bosons emerge and how they play the role in restoring the original symmetry operations. The authors have shown here an important relationship between the isovector collective states and symmetry rearrangement in nuclei. The interplay of strong and electromagnetic interactions leads to a finite energy gap for the isomagnons. The role of isomagnons in the low energy excitations has important consequences for {beta}-decay and it is anticipated in the excitation and decay of the matter in a heavy-ion collision. They have calculated the full response function of the Isobaric Analog State (IAS) at zero temperature and the finite temperature response function is analyzed at small T and long wavelength. The present approach of symmetry rearrangement and collective states has established a unified approach to the isovector collective states in nuclei and to collective states in all many-particle systems. This was the conjecture of Hiroomi Umezawa when a study was initially started of symmetry rearrangement in nuclear systems in analogy to his previous studies in condensed matter systems. The authors believe that they have established, at least partially, the vision of Hiroomi Umezawa.

Collective Motion of Spherical Bacteria  

PubMed Central

A large variety of motile bacterial species exhibit collective motions while inhabiting liquids or colonizing surfaces. These collective motions are often characterized by coherent dynamic clusters, where hundreds of cells move in correlated whirls and jets. Previously, all species that were known to form such motion had a rod-shaped structure, which enhances the order through steric and hydrodynamic interactions. Here we show that the spherical motile bacteria Serratia marcescens exhibit robust collective dynamics and correlated coherent motion while grown in suspensions. As cells migrate to the upper surface of a drop, they form a monolayer, and move collectively in whirls and jets. At all concentrations, the distribution of the bacterial speed was approximately Rayleigh with an average that depends on concentration in a non-monotonic way. Other dynamical parameters such as vorticity and correlation functions are also analyzed and compared to rod-shaped bacteria from the same strain. Our results demonstrate that self-propelled spherical objects do form complex ordered collective motion. This opens a door for a new perspective on the role of cell aspect ratio and alignment of cells with regards to collective motion in nature. PMID:24376741

Collective Behaviour without Collective Order in Wild Swarms of Midges  

PubMed Central

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

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.


University of Florida Digital Collections: Florida Photograph Collections  

NSDL National Science Digital Library

Florida is much, much more than a certain rather large theme park and the bustling nightlife of South Beach. Anyone with a cursory interest in the history of the Sunshine State should make a beeline for this engaging site. Created by the University of Florida Digital Collections, the Florida Photograph collection contains thousands of images related to the history and culture of the state. The collection features a number of subcollections, including Florida Ephemera and Concrete Blog: Messages on the Wall. The Concrete Blog section offers a fascinating portrait of Gainesville's 34th Street Wall, which has served as a community sounding board and place of artistic reflection for over 30 years. Neophytes can also type a few keywords into the search engine to get started; they might do well to begin with Tampa, Apalachicola, or hotels.

Bohunice Simulator Data Collection Project  

SciTech Connect

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 Middle East Water Collection  

NSDL National Science Digital Library

The subject of water is of increasing global importance, and access to water will continue to be a divisive issue in the coming years. This fascinating collection from the Oregon State University Libraries brings together approximately 9,000 items on political, socio-economic, demographic, and legal issues of water in the Middle East. The collection was started by Thomas Naff, professor emeritus of Asian and Middle Eastern Studies. The primary goal of this online collection is "to gain a better perspective on how water issues thread through and across many disciplines of thought - irrespective of borders or boundaries, cultures or historical differences." On the site, visitors will find they can search the materials by region or country, basins, or a drop-down menu of subject headings, which include finance, industry, and hydrology. Interested parties who plan on returning to the site can create a collection of their favorite items, and they can also use the Help area to get assistance on using the collection.


In search of exceptional collections  

NASA Astrophysics Data System (ADS)

The following thesis deals mainly with two different problems, both of which are related to the study of exceptional collections of sheaves. 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).

Max Hunter Folk Song Collection  

NSDL National Science Digital Library

Edited by Michael F. Murray, Assistant Professor of Music at Southwest Missouri State University, this site is a terrific resource for students and fans of traditional American music. The site offers numerous selections from the Max Hunter Collection, an archive of almost 1,600 Ozark Mountain folk songs, recorded between 1956 and 1976. Hunter was a travelling salesman from Springfield, Missouri who took his reel-to-reel tape recorder with him into the rural Ozarks, recording the songs and stories of people he met. The collection may be keyword searched or browsed by song title, singer, or catalog number. Featured songs list the singer, location, and date and include a transcription of the verses, in some cases a musical score, and links to an audio recording in RealPlayer, high-quality AIFF, and for some selections, MIDI formats. This site is yet another example of how the Internet offers free worldwide access to unique and priceless collections.


Fossil Collection and Museum Curation  

NSDL National Science Digital Library

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.

Collective modes in Ising lattices  

SciTech Connect

The effect of collective modes on the otherwise local structure of Ising lattices is investigated by studying a number of exactly solvable models. First, the open one-dimensional Ising model serves to define sharp locality. This feature then remains upon extension to a Bethe lattice, despite the existence of a phase transition. But insertion of periodic boundary conditions creates a collective mode which breaks locality in a very specific fashion. A model interface is analyzed to show that even when locality is not broken, local uniformity can become untenable.

Distributed Control with Collective Intelligence  

NASA Technical Reports Server (NTRS)

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.

The power of collective ambition.  


In the past few years, some companies have not just weathered the economic storm: They've emerged stronger than ever. How did such players as Four Seasons, Sephora, and Standard Chartered Bank defy conventional logic? Instead of pursuing a single ambition, such as profits, employees defined a collective ambition. As a result, those organizations deepened their engagement with employees and other stakeholders and became sustainably profitable. Purpose, a company's reason for existence, is the central element of collective ambition. The other elements--vision, targets and milestones, strategic and operational priorities, brand promise, core values, and leader behaviors--must be aligned to serve the company's purpose. Articulating the elements of collective ambition can give everyone in the organization a better sense of the company's purpose and how they can contribute to it. Purpose does not have to be about saving the world; providing excellent entertainment or banking services is just as meaningful a purpose as improving health care in emerging economies--as long as it is an authentic representation of why the company exists. To shape and then achieve a collective ambition, companies must strengthen their organizational glue (the collaborative engagement that creates a unified culture) and grease (the disciplined execution that enterprisewide change initiatives require).

Sheldon Harris Sheet Music Collection  

NSDL National Science Digital Library

Sheldon Harris was an avid record collector, and he began his collection as a young man growing up in Brooklyn. During his life, he also served as the blues editor of "Jazz & Pop Magazine", and also found time to publish an important biographical dictionary of blues singers and an oral history of jazz as told by jazz trombonist and blues singer, Clyde E.B. Bernhardt. This particular digital sheet music collection pays tribute to his work, and it was created by The University of Mississippi Department of Archives and Special Collections. Visitors can browse the sheet music at their leisure, and the holdings are particularly strong in the blues and early minstrel numbers. There are a number of ways to complete searches, as users can browse the selections by creator, decade, publisher, or geographic region. Items of note in the collection include "Jazzin' the Blues Away", "I'm Saving Up The Means To Get To New Orleans" and the W.C. Handy-penned classic "Memphis Blues".



Powder collection apparatus/method  


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. 4 figures.

Mapping collective emotions to make sense of collective behavior.  


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

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.


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".

Telling the story of Louisville's African American community is an ambitious goal and the University of Louisville's Oral History Center has done a fine job with this website. The process began in the 1970s with funding from the Kentucky Oral History Commission, which supported the collection's first batch of interviews. A wide range of people was interviewed for the project, including politicians, doctors, musicians, and educators as well as "regular folks." Currently, there are 27 interviews, and visitors can browse through them to get a sense of the offerings. One particularly fascinating interviewee is Dr. Jesse Bell, a longtime physician in Louisville. The collection will intrigue historians, urbanologists, and others with a passion for the American experience.



Overcoming Communication Restrictions in Collectives  

NASA Technical Reports Server (NTRS)

Many large distributed system are characterized by having a large number of components (eg., agents, neurons) whose actions and interactions determine a %orld utility which rates the performance of the overall system. Such collectives are often subject to communication restrictions, making it difficult for components which try to optimize their own private utilities, to take actions that also help optimize the world utility. In this article we address that coordination problem and derive four utility functions which present different compromises between how aligned a component s private utility is with the world utility and how readily that component can determine the actions that optimize its utility. The results show that the utility functions specifically derived to operate under communication restrictions outperform both traditional methods and previous collective-based methods by up to 75%.

Collective behavior in financial markets  

NASA Astrophysics Data System (ADS)

The financial market is an example of a complex system characterized by a highly intricate organization and the emergence of collective behavior. In this paper, this emergent dynamics in the financial market is quantified by using concepts of network synchronization. We consider networks constructed by the correlation matrix of asset returns and study the time evolution of the phase coherence among stock prices. It is verified that during a financial crisis a synchronous state emerges in the system, defining the market's direction. Furthermore, the paper proposes a statistical regression model able to identify the topological features that mostly influence such an emergence. The coefficients of the proposed model indicate that the average shortest path length is the measurement most related to network synchronization. Therefore, during an economic crisis, the stock prices present a similar evolution, which tends to shorten the distances between stocks indicating a collective dynamics.

This collection is a great way to explore the world and perhaps will inspire a new passion.


Current collection in a magnetoplasma  

NASA Technical Reports Server (NTRS)

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.

Collective communication routines in PVM  

SciTech Connect

The collective communication routines of scatter, gather, and reduce are frequently implemented as part of the native library for parallel architectures. These operations have been implemented in PVM for use among a heterogeneous system of workstations and parallel computers forming a virtual parallel machine. In the case of the Intel Paragon machines, the PVM implementation of the reduce operation utilizes the corresponding native mode library routines whenever possible. This paper describes the implementation of these collective communication routines in PVM including the utilization of the Intel Paragon native mode operations. Performance data is also given comparing the use of the native Intel Paragon collective routines and the PVM implementation on top of these routines on a dedicated Intel Paragon. For our timing results an average latency of 109 {mu}s is incurred using PVM as compared to the native Intel global sum routine. This extra startup is independent of the size of the message being sent and the number of nodes in the group. It is demonstrated that the use of static groups is preferable in time efficiency over the use of dynamic groups.

Walter Gordon Collection of Photographs  

NSDL National Science Digital Library

In the first half of the 20th century, the well-known African American attorney Walter L. Gordon had his office next to the African American newspaper, the California Eagle. The photographers for the paper often shot pictures of Black social life in Los Angeles, and once printed these photos were often discarded. Gordon saved many of these photos and began collecting the images, which often depicted leading members of the Black community in Los Angeles. His collection made its way to UCLA, and their digital collections group digitized over 800 of his photographs. Here visitors will find images of black resorts such as Val Verde, local political figures, and a range of jazz legends, such as Count Basie and Billie Holliday. Currently, visitors can view almost 300 of these items, and they can browse the photos by language, name, subject, or type. There are some real gems in here, including a great photo of Lionel Hampton on the stage and a cast photo of the members of "Carmen Jones" at an informal gathering. The image viewer here is quite impressive, as visitors can add a grid of select photos for comparative viewing and also manipulate each image as they see fit.


Oregon Multicultural Archives Digital Collection  

NSDL National Science Digital Library

Ethnic minorities in Oregon are the subject of this Oregon State University Library website and the collection "consists of images that document the lives and activities of ethnic minorities in Oregon." With its streamlined homepage, visitors can focus on the collection and how to search or browse through it. Visitors are also welcome to contribute information on any unidentified photographs, by clicking on "Contact Us", near the bottom of the homepage. In addition, visitors can also click on the "Browse" link to see every one of the 239 items in the collection. Those users with something more specific in mind should use the "Quick Links" drop down box in the top right hand corner of the homepage. Some of the subject areas that can be searched for are "African Americans", "Indians of North America", "Mexican Americans", "Political Parades and Rallies", and "Powwows". The "Indexes" available to search are organized into headings like "Photographer", "Subject" and "Geographic", and they can be found below the "Quick Links" drop down box.


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".


Electrospray Collection of Lunar Dust  

NASA Technical Reports Server (NTRS)

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.

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.

Collection Metadata Solutions for Digital Library Applications  

NASA Technical Reports Server (NTRS)

Within a digital library, collections may range from an ad hoc set of objects that serve a temporary purpose to established library collections intended to persist through time. The objects in these collections vary widely, from library and data center holdings to pointers to real-world objects, such as geographic places, and the various metadata schemas that describe them. The key to integrated use of such a variety of collections in a digital library is collection metadata that represents the inherent and contextual characteristics of a collection. The Alexandria Digital Library (ADL) Project has designed and implemented collection metadata for several purposes: in XML form, the collection metadata "registers" the collection with the user interface client; in HTML form, it is used for user documentation; eventually, it will be used to describe the collection to network search agents; and it is used for internal collection management, including mapping the object metadata attributes to the common search parameters of the system.

Collective sensing and collective responses in quorum-sensing bacteria  

PubMed Central

Bacteria often face fluctuating environments, and in response many species have evolved complex decision-making mechanisms to match their behaviour to the prevailing conditions. Some environmental cues provide direct and reliable information (such as nutrient concentrations) and can be responded to individually. Other environmental parameters are harder to infer and require a collective mechanism of sensing. In addition, some environmental challenges are best faced by a group of cells rather than an individual. In this review, we discuss how bacteria sense and overcome environmental challenges as a group using collective mechanisms of sensing, known as ‘quorum sensing’ (QS). QS is characterized by the release and detection of small molecules, potentially allowing individuals to infer environmental parameters such as density and mass transfer. While a great deal of the molecular mechanisms of QS have been described, there is still controversy over its functional role. We discuss what QS senses and how, what it controls and why, and how social dilemmas shape its evolution. Finally, there is a growing focus on the use of QS inhibitors as antibacterial chemotherapy. We discuss the claim that such a strategy could overcome the evolution of resistance. By linking existing theoretical approaches to data, we hope this review will spur greater collaboration between experimental and theoretical researchers. PMID:25505130

Towards a psychology of collective memory  

Microsoft Academic Search

This article discusses the place of psychology within the now voluminous social scientific literature on collective memory. Many social scientists locate collective memories in the social resources that shape them. For scholars adopting this perspective, collective memories are viewed as transcending individuals; that is, as being “in the world”. Others recognise that, in the final analysis, individuals must remember collective

The Sheffield data collection system.  


Because of the intrinsically low sensitivity of any surface potential measurement to resistivity changes within a volume conductor, any data collection system for impedance imaging must be sensitive to changes in the peripheral potential profile of the order of 0.1%. For example, whilst the resistivity changes associated with lung ventilation and the movement of blood during the cardiac cycle range from 3 to 100% the changes recorded at the surface are very much less than this. The Sheffield data collection system uses 16 electrodes which are addressed through 4 multiplexers. Overall system accuracy is largely determined by the front-end equivalent circuit which is considered in some detail. This equivalent circuit must take into account wiring and multiplexer capacitances. A current drive of 5 mA p-p at 5 kHz is multiplexed to adjacent pairs of electrodes and peripheral potential profiles are recorded by serially stepping around adjacent electrode pairs. The existing Sheffield system collects the 208 data points for one image in 79 ms and offers 10 image data sets per second to the microprocessor. For a homogeneous circular conductor the ratio of the maximum to minimum signals within each peripheral potential profile is 45:1. The temptation to increase the number of electrodes in order to improve resolution is great and an achievable performance for 128 electrodes is given. However, any improvement in spatial resolution can only be made at the expense of speed and sensitivity which may well be the more important factors in determining the clinical utility of APT.

Invariants of collective neutrino oscillations  

NASA Astrophysics Data System (ADS)

We consider the flavor evolution of a dense neutrino gas by taking into account both vacuum oscillations and self-interactions of neutrinos. We examine the system from a many-body perspective as well as from the point of view of an effective one-body description formulated in terms of the neutrino polarization vectors. We show that, in the single angle approximation, both the many-body picture and the effective one-particle picture possess several constants of motion. We write down these constants of motion explicitly in terms of the neutrino isospin operators for the many-body case and in terms of the polarization vectors for the effective one-body case. The existence of these constants of motion is a direct consequence of the fact that the collective neutrino oscillation Hamiltonian belongs to the class of Gaudin Hamiltonians. This class of Hamiltonians also includes the (reduced) BCS pairing Hamiltonian describing superconductivity. We point out the similarity between the collective neutrino oscillation Hamiltonian and the BCS pairing Hamiltonian. The constants of motion manifest the exact solvability of the system. Borrowing the well established techniques of calculating the exact BCS spectrum, we present exact eigenstates and eigenvalues of both the many-body and the effective one-particle Hamiltonians describing the collective neutrino oscillations. For the effective one-body case, we show that spectral splits of neutrinos can be understood in terms of the adiabatic evolution of some quasiparticle degrees of freedom from a high-density region where they coincide with flavor eigenstates to the vacuum where they coincide with mass eigenstates. We write down the most general consistency equations which should be satisfied by the effective one-body eigenstates and show that they reduce to the spectral split consistency equations for the appropriate initial conditions.

Statistical analysis in MSW collection performance assessment.  


The increase of Municipal Solid Waste (MSW) generated over the last years forces waste managers pursuing more effective collection schemes, technically viable, environmentally effective and economically sustainable. The assessment of MSW services using performance indicators plays a crucial role for improving service quality. In this work, we focus on the relevance of regular system monitoring as a service assessment tool. In particular, we select and test a core-set of MSW collection performance indicators (effective collection distance, effective collection time and effective fuel consumption) that highlights collection system strengths and weaknesses and supports pro-active management decision-making and strategic planning. A statistical analysis was conducted with data collected in mixed collection system of Oporto Municipality, Portugal, during one year, a week per month. This analysis provides collection circuits' operational assessment and supports effective short-term municipality collection strategies at the level of, e.g., collection frequency and timetables, and type of containers.

New Type of Collective Accelerator  

NASA Astrophysics Data System (ADS)

Described here is a collective accelerator based on magnetically confined plasma rings. Typical rings which have been produced and which have 10-kJ magnetic energy and 0.1 to 10 C of nuclei are predicted to be accelerated magnetically to 10 MJ or higher in acceleration lengths of 100 m. Applications are discussed of current drive in tokamak fusion reactors, fueling and heating magnetic fusion reactors, transuranic element synthesis, and, for focused rings, a high-energy density driver for inertial confinement fusion.

The neurobiology of collective action  

PubMed Central

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

Moving on, the theatre arts area contains images, programs and other bits of ephemera from shows like Cabaret, Cinderella, and much more.


Entanglement and Collective Quantum Operations  

E-print Network

We show how shared entanglement, together with classical communication and local quantum operations, can be used to perform an arbitrary collective quantum operation upon N spatially-separated qubits. A simple teleportation-based protocol for achieving this, which requires 2(N-1) ebits of shared, bipartite entanglement and 4(N-1) classical bits, is proposed. In terms of the total required entanglement, this protocol is shown to be optimal for even N in both the asymptotic limit and for `one-shot' applications.

University of Mississippi Visual Collections: John Elon Phay Collection  

NSDL National Science Digital Library

In 1953 the Mississippi State Legislature called an extraordinary session in order to rewrite the laws governing the public school systems throughout the state. As a result of this session, the legislature created the State Educational Finance Commission. One of their mandates was to make sure that each county submitted a plan for the reorganization of its school system. Part of the documentation created as part of this process included photographs of every school across the state. This digital collection offers selected Kodachrome images taken during the mid-1950s in Benton, Clay, Grenada, and Jones Counties. Interested parties can view the slides via the "School Index" or the "Slide Index" area. The images feature students at play, in science labs, home economics classes, and other settings. Overall, it's a fascinating and troubling document that looks at the phenomenon of segregated educational facilities during this historical period.


University of Washington Digital Collections: Panorama Photographs Collection  

NSDL National Science Digital Library

Washington is a state chock-full of fine vistas and panoramic views, so it stands to reason that they would have some great panoramic photographs. The University of Washington Libraries has created this collection to pay tribute to such items, and they have included sweeping city views of Seattle, University of Washington campus scenes, and Japanese American organizations. First-time visitors should read the highly informative essay, "History of Panoramic Photography" to become familiar with the nuances of this artistic and documentary tradition. After this, they can look at over 100 panoramic photographs that include a dramatic shot of battleships docked at the Puget Sound Naval Shipyard in 1910 and an early image of the town of Kent, Washington. The site is rounded out by links to two additional essays from the Library of Congress Prints and Photographs Divisions.


Collective credit allocation in science  

PubMed Central

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.

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.



Collectivity of exotic silicon isotopes  

NASA Astrophysics Data System (ADS)

The determination of the strength of the electric quadrupole transition between the ground state and first excited state with spin-party Jpi = 2+ (the B (E2; 0+ ? 2+) value) in an even-even nucleus provides a measurement of the low-lying quadrupole collectivity. The B(E2) values for the Z=14 nuclei 34,36,38,40,42Si were measured via intermediate-energy Coulomb excitation at the National Superconducting Cyclotron Laboratory in East Lansing, Michigan. The secondary beams were produced by the fragmentation of a 48 Ca primary beam guided onto a high-Z secondary target. De-excitation gamma-rays, indicative of the inelastic process, were detected with the high-efficiency scintillator array CAESAR, located around the secondary target position of the S800 Spectrograph, in coincidence with scattered particles tracked on an event-by-event basis in the Spectrograph. The results comprise the first measurements of the quadrupole collectivity of 40,42Si. The measured B(E2) values are compared to large-scale shell model calculations and provide insight into the evolution of shell structure and deformation in this region.

The determination of the electric quadrupole transition strength between the ground state and first excited state with spin-party of J^?=2^+ (the B(E2; 0^+-> 2^+) value) in an even-even nucleus provides a measurement of the low-lying quadrupole collectivity. The B(E2) values for ^34,36,38,40,42Si were measured via intermediate-energy Coulomb excitation at NSCL. The secondary beams were produced by fragmentation of ^48Ca primary beam and guided onto a high-Z target. De-excitation gamma rays indicating the inelastic process were detected around the target position with the high efficiency scintillator array CAESAR in coincidence with scattered projectiles tracked on an event-by-event basis in the S800 spectrograph. The results comprise the first measurements of the quadrupole collectivity of ^40Si and ^42Si and probe the persistence of the N=28 magic number. The measured B(E2) values are compared to large-scale shell model calculations and provide insight into the evolution of shell structure and deformation in this region.

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.


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.


Selective altruism in collective games  

NASA Astrophysics Data System (ADS)

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.

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.

GeoAstro Applet Collection  

NSDL National Science Digital Library

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.

Barnard-Stockbridge Photograph Collection  

NSDL National Science Digital Library

In 1964, the University of Idaho Library received a collection of over 200,000 nitrocellulose and glass plate negatives taken by Nellie Stockbridge and one T.N. Barnard. Barnard was the founder of a prominent photo studio in Wallace, Idaho, and he ran the establishment for ten years until 1898, when he sold it to Nellie Stockbridge. Both individuals had a keen interest in the environment around them, and as such, they documented floods, tree lines, fires, and shots of town life. The University of Idaho Library has placed over 700 of these images online here, and visitors can browse around at their leisure, or perform a keyword search across the items. The photos provide an excellent visual record of this late 19th century environment, and also serve as a record of environment degradation and land use patterns.


Enhanced collectivity in 74Ni  

NASA Astrophysics Data System (ADS)

The neutron-rich nucleus 74Ni was studied with inverse-kinematics inelastic proton scattering using a 74Ni radioactive beam incident on a liquid hydrogen target at a center-of-mass energy of 80 MeV. From the measured de-excitation ? rays, the population of the first 2+ state was quantified. The angle-integrated excitation cross section was determined to be 14(4) mb. A deformation length of ?=1.04(16) fm was extracted in comparison with distorted wave theory, which suggests that the enhancement of collectivity established for 70Ni continues up to 74Ni. A comparison with results of shell model and quasi-particle random phase approximation calculations indicates that the magic character of Z=28 or N=50 is weakened in 74Ni.

Devices for collecting chemical compounds  


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.

George Washington Carver Digital Collection  

NSDL National Science Digital Library

George Washington Carver was many things to many people: at various points in his life he was a scholar, teacher, inventor, and student. From humble roots in southwestern Missouri, Carver went on to wear many hats. This fine digital collection from the Iowa State University brings together over 200 photographs, letters, and other items held in the ISU archives. The majority of the correspondence here is between Carver and his mentor, Dr. Louis Pammel, and their words cover a wide variety of topics, including peanuts, scientific experimentation, and so on. There are many wonderful photos of Carver, including his graduation photo from 1893, taken the year before he formally graduated from the Iowa Agricultural College. Visitors who might be less familiar with the contours of Carver life may also wish to read the narrative essay on his life by Toby Fishbein.



Enhanced collectivity in 74Ni  

E-print Network

The neutron-rich nucleus 74Ni was studied with inverse-kinematics inelastic proton scattering using a 74Ni radioactive beam incident on a liquid hydrogen targetat a center-of-mass energy of 80 MeV. From the measured de-excitation gamma-rays, the population of the first 2+ state was quantified. The angle-integrated excitation cross section was determined to be 14(4) mb. A deformation length of delta = 1.04(16) fm was extracted in comparison with distorted wave theory, which suggests that the enhancement of collectivity established for 70Ni continues up to 74Ni. A comparison with results of shell model and quasi-particle random phase approximation calculations indicates that the magic character of Z = 28 or N = 50 is weakened in 74Ni.

Fleet Assignment Using Collective Intelligence  

NASA Technical Reports Server (NTRS)

Product distribution theory is a new collective intelligence-based framework for analyzing and controlling distributed systems. Its usefulness in distributed stochastic optimization is illustrated here through an airline fleet assignment problem. This problem involves the allocation of aircraft to a set of flights legs in order to meet passenger demand, while satisfying a variety of linear and non-linear constraints. Over the course of the day, the routing of each aircraft is determined in order to minimize the number of required flights for a given fleet. The associated flow continuity and aircraft count constraints have led researchers to focus on obtaining quasi-optimal solutions, especially at larger scales. In this paper, the authors propose the application of this new stochastic optimization algorithm to a non-linear objective cold start fleet assignment problem. Results show that the optimizer can successfully solve such highly-constrained problems (130 variables, 184 constraints).

Real time psychrometric data collection  

SciTech Connect

Eight Mine Weather Stations (MWS) installed at the Waste Isolation Pilot Plant (WIPP) to monitor the underground ventilation system are helping to simulate real-time ventilation scenarios. Seasonal weather extremes can result in variations of Natural Ventilation Pressure (NVP) which can significantly effect the ventilation system. The eight MWS(s) (which previously collected and stored temperature, barometric pressure and relative humidity data for subsequent NVP calculations) were upgraded to provide continuous real-time data to the site wide Central monitoring System. This data can now be utilized by the ventilation engineer to create realtime ventilation simulations and trends which assist in the prediction and mitigation of NVP and psychrometric related events.

The University of Wisconsin Collection  

NSDL National Science Digital Library

As this digital archive of documents related to the history of the University of Wisconsin suggests, "...the history of the University of Wisconsin is far too colorful and texture-rich to be told in a single document." Fortunately for those with an interest in the University's long history, this special collection of historical documents developed by the University's Digital Content Group provides access to a number of helpful resources. A number of titles may be searched or browsed, including the landmark 4-volume history of the University of Wisconsin and a number of printed materials related to the Wisconsin Union, the University's primary gathering place. Visitors can also browse through two early versions of the University's yearbook, titled the Trochos.


Waterford Area Local History Collection  

NSDL National Science Digital Library

Located west of Racine and southwest of Milwaukee, the town of Waterford, Wisconsin sits along the Fox River. In addition to its scenic location, Waterford also happens to have a vibrant public library that has worked with other local organizations to create this elaborate digital local history archive. Working in partnership with the University of Wisconsin Digital Collections, they have created this digital home for an array of maps, photographs, books, manuscripts, and other printed ephemera. The thematic headings include "community", "maps", and "people and portraits" As the town served as a popular resort for decades, visitors will be delighted to learn that the archive has several dozen photographs of the various leisure pursuits that were popular throughout the town and its outlying areas.


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.


Scavenger Hunt: A Group Collection  

NSDL National Science Digital Library

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.
