A spider fibroin and its synthesis

The tissue-specific fibroin product of the large ampullate glands of the spider Nephila clavipes was isolated and analyzed with respect to homogeneity and size. The solubilized luminar contents of the glands migrate as a homogeneous band in SDS electrophoresis. Its molecular mass has been estimated to be approximately 323,600 daltons. Excised glands have been manintained metabolically active under rather simple culture conditions. Protein synthesis, monitored by incorporation of labeled alanine and glycine, has been elicited through exposure to a cholinergic agent in the culture medium as well as by depleting the animals of their store of silks.
Design and construction of an industrial ship conditioning system

This project is based on the design and construction of an industrial air conditioning system for the improvement of the working thermal comfort of workers that for various reasons there is the trend of the increase in body temperature are these by machines, equipment or the same work activities, which affects the productive performance and possible health risks. During development, the selection of mechanical equipment such as the fan, water pump, ventilation transport ducts is studied with high rates of energy efficiency. In the light of the above, the environmental economic partner alternative is chosen to implement the evaporative conditioning system, conducive to working in open places to lower the temperature by labor and technology installed in the production areas, as well as the extraction of fumes derived from production processes. The importance of the evaporative conditioning system is to derive the appropriate mechanisms to take advantage of the surface heat transfer of a panel and copper and aluminum coil using water, and thus take advantage of its temperature differential reaching 25oC, with an average humidity of 66% and energy consumption of 0.29 KW/h. To obtain results, the experimental field method, random cluster sampling, application of experimental observation sheets for the survey of diagnostic information of the current situation of the medium and equipment was applied.

Urban Sensing Systems with Additive Aggregation

:- Nowadays People-Centric Urban Sensing Systems has been commonly used in social, scientific and commercial applications. People-Centric Urban Sensing Systems refer to using human-carried mobile devices such as smart phones and tablets with ever-growing capabilities in sensing, computation, storage, and communications for urban-scale distributed data collection, analysis, and sharing to facilitate the interaction between humans and their surrounding environments. A main obstacle to the widespread deployment and adoption of PC-USSs are the privacy concerns of participating individuals as well as the concerns about data integrity. To tackle this open challenge, we introduce a new scheme of data aggregation for achieving data integrity and privacy which includes additive data aggregation functions like sum , variance ,count etc., IndexTerms: Privacy, aggregation, security. 1.
Identification of the Microbial Community Structure and Potential Mechanism of Environmental Adaptation in Contaminated Environments

Purpose: To assess the bacterial community structure and the possible mechanism underlying the environmental adaption in contaminated habitats.Methods: The 60-mer oligonucleotide multibacterial microarray (GSE38004) was downloaded from the Gene Expression Omnibus database. The changes in the abundance of bacterial populations and genes in contaminated habitats were assessed based on the gene expression profiles. Then the potential function of the genes and their involved pathways were predicted by a bioinformatics approach.Results: A total of 25 bacterial populations had different abundance between contaminated habitats and uncontaminated area, of which Sphingobium herbicidovorans (S. herbicidovorans) and Pseudomonas pavonaceae (P. pavonaceae) involved in 23 populations were determined to have higher abundance in contaminated areas. Additionally, 184 genes involved in anaerobic respiration and cellular respiration were detected to have potential bioremediation. The genes of MDH (Mannitol-1-phosphate/altronate dehydrogenases) and fadE (acyl-CoA dehydrogenase) may play key roles in the mechanism of metabolic adaption.Conclusions: S. herbicidovorans and P. pavonaceae were the predominant bacterial groups in contaminated sites for the various metabolic potential and antibiotic resistances. The significant genes (MDH, fadE) and pathways (citrate cycle, pyruvate metabolism, fatty acid metabolism) played key roles in the adaptive response of microorganisms in contaminated environment.
Accumulation of a 22‐kDa protein and its mRNA in the leaves of Raphanus sativus in response to salt stress or water deficit

The response of 10-day-old seedlings of Raphanus sativus L. cv. Fakir to salt stress (100 mM to 200 mM NaCl) was investigated. Three weeks after initiation of salt treatment, the fresh weight of the shoots of salt-treated plants was half that of untreated plants. The salt stress resulted in the accumulation of Na+, preferably in the old leaves. The K+ level was reduced by as much as 50% in the old leaves of NaCl-treated plants, whereas this reduction was only 20–25% in the young leaves. Free proline accumulated in all aerial organs, and the highest levels were found in the young leaves. Patterns of total proteins extracted from the leaves of control or salt-treated plants were compared. The most obvious change concerned a 22-kDa, pl 7.5 polypeptide, which accumulated after exposure of the plants to NaCl. The appearance of this polypeptide was also mediated by a rapid drought stress, and sequencing indicated that it is related to the Kunitz protease inhibitor family. A cDNA clone corresponding to the radish 22-kDa polypeptide was obtained and sequenced. Northern blot analysis showed that salt stress induces a large accumulation of this mRNA in the leaves of radish.
Influence of Feed Deprivation on Hematology, Macrophage Chemotaxis, and Resistance to Edwardsiella ictaluri Challenge of Channel Catfish

Abstract Two experiments were conducted to evaluate the effects of four feeding regimens (no feeding, feeding once daily to satiation, feeding every other day to satiation, and no feeding for 3 weeks followed by feeding once daily to satiation during the fourth week) on the growth, feed efficiency, hematology, immune response, and resistance to Edwardsiella ictaluri of channel catfish Ictalurus punctatus. Feed efficiency ratios were a reflection of weight gain and differed significantly (P < 0.05) among treatments in one experiment but not the other. Survival rates did not differ significantly among feeding regimens in either experiment. Fish that were not fed or fed only in the fourth week were anemic. Macrophage chemotaxis in response to an E. ictaluri exoantigen was significantly different among treatments, with the lowest response in the group that was not fed and the highest in the group that was fed daily. Mortality from enteric septicemia of catfish (ESC) was significantly lower for fish that were .
Biomass allocation and growth rates in Pinus sylvestris are interactively modified by nitrogen and phosphorus availabilities and by tree size and age

Biomass allocation and growth of Scots pine, Pinus sylvestris L. , of various sizes (height 0.03-20 m) and ages (1-151 years) were investigated in two infertile sites (raised bog and sand dunes) to determine relative nitrogen and phosphorus limitations on productivity and their interactions and size-dependent controls. Dry mass weighted aver- age nitrogen (NW) and phosphorus (PW) contents were higher in P. sylvestris in sand dunes than in those in the raised bog, but PW/NW ratios overlapped between the sites. Leaf dry mass ratio (FL) and leaf-area ratio (LAR) increased with NW, and FL increased with PW. The relative growth rate (RG) was more strongly associated with PW than with NW. The net assimilation rate per leaf dry mass (NARM) scaled positively with PW but not with NW, demonstrating that the stronger effect of PW on growth was due to modified biomass allocation and physiology (RG =N ARM ×F L), while NW affected growth via biomass allocation. Partitioning and growth characteristics were poorly related to the PW/NW ratio. The overall decrease of growth in larger trees resulted from their lower LAR and FL. Increases in size further led to a lower NW but higher PW. We conclude that optimum productivity at a given NW requires a certain minimum PW, not a specific "non-limiting" PW/NW ratio. While nutrients affect growth by changing biomass allocation and physiological activity, size primarily modifies biomass allocation.
Seasonal use by birds of stream-side riparian habitat in coniferous forest of northcentral British Columbia

To determine use of riparian habitats by birds in the northern coniferous forest of British Columbia, we censused birds and vegetation along 500 m transects placed parallel and perpendicular to three second-order streams. Censuses were conducted during spring, summer, autumn, and winter to investigate how use of riparian habitat changed seasonally. Stream-side riparian zones were characterized by a dense understorey of deciduous vegetation not found in the upslope forest. Nine bird species preferred the riparian understorey for breeding, six preferred it only during migration. Neotropical migrants (16 of 46 species) were more closely associated with stream-sides than year-round residents (11 species). Some breeding birds (five species) were significantly negatively associated with riparian habitats. The density of riparian birds declined with distance upstream but did not decline up to 250 m away from the stream. The more extensive riparian areas downstream supported a greater density of birds in all seasons compared to upstream areas, but more species only in spring and autumn. Species that nested in non-riparian areas in summer used riparian habitat in autumn, making riparian corridors in the northern coniferous forest important during migration. Maintaining both riparian and upslope habitats is necessary to preserve species diversity al the landscape level.
Supply Chain Business Intelligence and the Supply Chain Performance: The Mediating Role of Supply Chain Agility

The study has planned to examine the impact of the supply chain business intelligence on the supply chain performance of the Indonesian firms. Additionally, the study has examined the mediating role of agile capability and supply chain capability. For data gathering, total 450 questionnaires were distributed and obtained only 325 questionnaires. During data screening process 23 questionnaires were excluded, since they were incomplete. Therefore, we obtained 67% response rate for the survey in present study. Partial Least Square-Structural Equation Modeling (PLS-SEM) is an important statistical procedure to carry out multivariate data analysis, Empirical analysis in this study supports the supply chain business intelligence competence with respect to technical, cultural and managerial competence. This indicates that it is necessary to utilize appropriate technologies and tools and have well-defined processes, although these are not sufficient conditions to develop business intelligence product efficiently and effectively, such as, relevant knowledge and information which facilitate in the decision-making functions of the supply chain. Besides, some inter- and intra-organizational culture elements also affect the business intelligence product creation. The prior research further supported the significance of knowledge/information-related competences to enhance agile performance characteristics and competitive performance of the supply chain.
to yield for automated

What will cyclists do in future conﬂict situations with automated cars at intersections when the cyclist has the right of way? Inorder to explore this, short high-quality animation videos of conﬂicts between a car and a cyclist at ﬁve different intersections were developed. These videos were ‘shot’ from the perspective of the cyclist and ended when a collision was imminent should the car or the bicyclist not slow down. After each video participants indicated whether they would slow down or continue cycling, how conﬁdent they were about this decision, what they thought the car would do, and how conﬁdent they were about what the carwould do. The appearance of the approaching car was varied as within-subjects variable with 3 levels (Car type): automated car, automated car displaying its intentions to the cyclists,andtraditionalcar.Inallsituationsthecyclisthadrightofway. Ofeachconﬂict,three versionsweremadethatdifferedinthemomentthatthevideoendedbycuttingofffractions from the longest version, thus creating videos with an early, mid, and late moment for the cyclist to decide to continue cycling or to slow down (Decision moment). Before the video experiment started the participants watched an introductory video about automated vehicles that served as prime. This video was either positive, negative, or neutral about automated vehicles (Prime type). Both Decision moment and Prime type were between subject variables. After the experiment participants completed a short questionnaire about trust in technology and trust in automated vehicles. 1009 participants divided in nine groups (one per Decision moment and Prime) completed the online experiment in which they watched ﬁfteen videos (5 conﬂicts (cid:1) 3 car types). The results show that participants more oftenyieldedwhentheapproachingcarwasanautomatedcarthanwhenitwasatraditional car. However, when the approaching car was an automated car that could communicate its intentions,theyyieldedlessoftenthanforatraditionalcar.TheearliertheDecisionmoment, the more often participants yielded but this increase in yielding did not differ between the three car types. Participants yielded more often for automated cars (both types) after they watched the negative prime video before the experiment than when they watched the positive video. The less participants trusted technology, and the capabilities of automated vehicles in particular, the more they were inclined to slow down in the conﬂict situations with automated cars. The association between trust and yielding was stronger for trust in the capabilities of automated vehicles than for trust in technology in general.
Etrumeus makiawa, a New Species of Round Herring (Clupeidae: Dussumierinae) from the Hawaiian Islands1

Abstract: Etrumeus makiawa is described as a new species of round herring from the Hawaiian Islands. Formerly identified as E. micropus (type locality, Japan), it is distinct from that species in having modally one fewer pectoral ray and 48–51 gill rakers, compared with 44–48 for E. micropus. Japanese and Hawaiian Etrumeus compose reciprocally monophyletic mtDNA lineages (d = 4.60%) with a long period of separation (ca. 2.3 million yr). This new Hawaiian endemic is also differentiated from E. acuminatus in California and Baja California, which instead has a count of 41–45 gill rakers, a larger maximum size (to 280 mm SL, compared with 198 mm for E. makiawa), and a clearly different mtDNA sequence (d = 2.20%). The northwestern Atlantic species, E. sadina (E. teres is a synonym), has 49–54 gill rakers and is genetically differentiated from all the other species considered here (d = 15.95% to 17.58%).
Stereoscopic Studies of Cells and Viruses in the Electron Microscope

The electron microscope has two big advantages over its older cousin, the light microscope. The first of these is its high resolution, 0.002 pL as compared to a resolution of only 0.2 p, for the light microscope. By dint of this resolution the electron microscope has already given a number of indications on an almost molecular scale of how certain cellular constituents and products are arranged. The second advantage, which is less well known, is the great depth of focus of the electron microscope, which, being about ten times that of the light microscope, makes stereoscopic electron microscopy possible. However, until recently the stereoscopic determination of form has been applied only to certain rugged biological elements such as butterfly scales and diatom shells which can withstand drying. To the biologist the principal disadvantage of the electron microscope is this fact. Most of his specimens, containing water as an essential part, must be freed of all volatile material before they can be studied in the high vacuum of the instrument. The electron microscope permits the study of only dry and dead objects. In view of this limitation we should be well content if we could only dry our material in such a way that its form is not distorted. The primary source of distortion during air-drying is the relatively enormous force exerted by surface tension as water evaporates from the specimen. The magnitude of these forces may be appreciated by reference to figures 1 and 2 where the stresses acting on two types of microscopic struc
Optimal Design of a Plenum Fan with Three-Dimensional Blades

We successfully designed an optimized plenum fan with a three-dimensional, smooth, curved blade. The optimized model revealed that the static pressure in the channel had been increased uniformly and stably, and the flow separation at the leading edge was significantly reduced. According to simulations, the three-dimensional blade stabilized the fluid flow, and the flow friction was reduced by suppressing the flow separation as much as possible so that both the static pressure and the static efficiency were clearly improved in comparison with those of the original model. As a result, the static efficiency was improved by 6.3% compared with that of the original model.
Acquisition and retention of Xylella fastidiosa by an efficient vector, Graphocephala atropunctata.

The blue-green sharpshooter (BGSS), Graphocephala atropunctata (Signoret), is an efficient vector of Xylella fastidiosa Wells et al, the causal bacterium of Pierce's disease of grapevine. In experiments to assess changes over time in vector transmission efficiency and populations of bacteria in BGSS, 81 of 120 BGSS that were fed for 12 h on infected grapevine acquired the bacterium. Individual infective BGSS were exposed 4 times (1 h, and 7, 21, and 60 days after acquisition) to uninfected grapevines for 3-h inoculation feeding periods to determine the efficiency of transmission to grapevine. After each inoculation efficiency test, some BGSS were tested by culturing for X. fastidiosa to determine the bacterial population in the vector heads and bodies. Transmission efficiency increased from 56 to 92% between 1 h and 7 days post-acquisition, and remained high thereafter (91% at 21 days and 76% at 60 days). Bacterial population size in the heads of the inoculative vectors also increased between 1 h and 7 days, but did not consistently increase further. Xylella fastidiosa was not recovered by culture from about 40% of the inoculative insects. Populations below the detection limit (100 bacteria) in the BGSS heads were enough for efficient transmission
Orchard: Exploring Multivariate Heterogeneous Networks on Mobile Phones

People are becoming increasingly sophisticated in their ability to navigate information spaces using search, hyperlinks, and visualization. But, mobile phones preclude the use of multiple coordinated views that have proven effective in the desktop environment (e.g., for business intelligence or visual analytics). In this work, we propose to model information as multivariate heterogeneous networks to enable greater analytic expression for a range of sensemaking tasks while suggesting a new, list‐based paradigm with gestural navigation of structured information spaces on mobile phones. We also present a mobile application, called Orchard, which combines ideas from both faceted search and interactive network exploration in a visual query language to allow users to collect facets of interest during exploratory navigation. Our study showed that users could collect and combine these facets with Orchard, specifying network queries and projections that would only have been possible previously using complex data tools or custom data science.
Synthesis and crystal structures of two layered Cu(I) and Ag(I) iodidometalates

Abstract Cu(I) and Ag(I) iodidometalates have been investigated for both their rich structural chemistry, as well as for useful properties like luminescence. Here, we present the synthesis and crystal structure of (BzA)[MI2] · 0.5 H2O (BzA = benzylammonium; M=Cu (1), Ag (2)). The two compounds are isostructural and show a previously unknown layered anion motif that can be described as a 44 net constructed via corner-sharing of M2I6 subunits, built from two edge-sharing MI4 tetrahedra.
A feedback loop links brownification and anoxia in a temperate, shallow lake

This study examines a natural, rapid, fivefold increase in dissolved organic carbon (DOC) concentrations in a temperate shallow lake, describing the processes by which increased DOC resulted in anoxic conditions and altered existing carbon cycling pathways. High precipitation for two consecutive years led to rising water levels and the flooding of adjacent degraded peatlands. Leaching from the flooded soils provided an initial increase in DOC concentrations (from a 2010 mean of 12 ± 1 mg L−1 to a maximum concentration of 53 mg L−1 by June 2012). Increasing water levels, DOC, and phytoplankton concentrations reduced light reaching the sediment surface, eliminating most benthic primary production and promoting anoxia in the hypolimnion. From January to June 2012 there was a sudden increase in total phosphorus (from 57 µg L−1 to 216 µg L−1), DOC (from 24.6 mg L−1 to 53 mg L−1), and iron (from 0.12 mg L−1 to 1.07 mg L−1) concentrations, without any further large fluxes in water levels. We suggest that anoxic conditions at the sediment surface and flooded soils produced a dramatic release of these chemicals that exacerbated brownification and eutrophication, creating anoxic conditions that persisted roughly 6 months below a water depth of 1 m and extended periodically to the water surface. This brownification‐anoxia feedback loop resulted in a near‐complete loss of macroinvertebrate and fish populations, and increased surface carbon dioxide (CO2) emissions by an order of magnitude relative to previous years.
