    Full Text Available Due to their complex composition, Merlot cultivar red grapes were subjected to maceration-fermentation as an important stage for the natural pigments and aroma compounds extraction. The purpose of this paper was the assessment of three pre-fermentation maceration techniques in order to improve wine's characteristics. For the experiment were used Merlot cultivar red grapes. The grapes were removed from their clusters, crushed and than transferred to three maceration techniques: microwave maceration at 650 W for 15 minutes, thermal maceration by heating the grape grains at 70 ⁰C for 20 minutes and classical maceration for 7 days at 20 ⁰C. During the process of maceration and fermentation all the samples were monitored considering the yeast cell count and alcohol content. The wine samples were evaluated in terms of colour, by spectrophotometric method. The evaluation of technological index, the evolution of the yeast cells and the fermentation parameters from the three samples indicate that the most advantageous fermentation procedure was classical maceration-fermentation.

    A chemometric treatment of the data obtained by gas chromatography (GC) with flame ionization detector (FID) has been proposed to study the maceration time involved in perfumes manufacture with the final purpose of reducing this time but preserving the organoleptic characteristics of the perfume that is being elaborated. In this sense, GC-FID chromatograms were used as a fingerprint of perfume samples subjected to different maceration times, and data were treated by linear discriminant analysis (LDA), by comparing to a set of samples known to be macerated or not, which were used as calibration objects. The GC-FID methodology combined with the treatment of data by LDA has been applied successfully to seven different perfumes. The constructed LDA models exhibited excellent Wilks' lambdas (0.013-0.118, depending on the perfume), and up to a reduction of 57% has been achieved with respect to the maceration time initially established. 2010 Elsevier B.V.

    Forensic anthropologists routinely macerate human bone for the purposes of identity and trauma analysis, but the heat and chemical treatments used can destroy genetic evidence. As a follow-up to a previous study on nuclear DNA recovery that used pig ribs, this study utilizes human skeletal remains treated with various bone maceration techniques for nuclear DNA amplification using the standard Combined DNA Index System (CODIS) markers. DNA was extracted from 18 samples of human lower leg bones subjected to nine chemical and heat maceration techniques. Genotyping was carried out using the AmpFlSTR COfiler and AmpFlSTR Profiler Plus ID kits. Results showed that heat treatments via microwave or Biz/Na(2)CO(3) in sub-boiling water efficiently macerate bone and produce amplifiable nuclear DNA for genetic analysis. Long-term use of chemicals such as hydrogen peroxide is discouraged as it results in poor bone quality and has deleterious effects on DNA amplification.

    In order to research how lignite is utilized, two coal samples of seams 2 and 4were taken from the Huangxian Basin, China. The samples were separated into vitrinite,sporinite, and resinite. Geo-chemical and pyrolysis methods were used to analyse three maceral groups and two seam samples. The results indicate that the resinite and sporinite groups have higher extract yields, S1, S2, HI values, and pyrolysis compounds.These differences may shed light on the usage of the Huangxian lignite. Seam 2 produces more gas and oil than seam 4 does because seam 2 contains more resinite and sporinite macerals.

    Arthropod-borne diseases remain a pressing international public health concern. While progress has been made in the rapid detection of arthropod-borne pathogens via quantitative real-time (qPCR), or even hand-held detection devices, a simple and robust maceration and nucleic acid extraction method is necessary to implement biosurveillance capabilities. In this study, a comparison of maceration techniques using five types of beads followed by nucleic acid extraction and detection were tested using two morphologically disparate arthropods, the Aedes aegypti mosquito and Xenopsylla spp. flea, to detect the zoonotic diseases dengue virus serotype-1 and Yersinia pestis. Post-maceration nucleic acid extraction was carried out using the 1-2-3 Platinum-Path-Sample-Purification (PPSP) kit followed by qPCR detection using the Joint Biological Agent Identification and Diagnostic System (JBAIDS). We found that the 5mm stainless steel beads added to the beads provided in the PPSP kit were successful in macerating the exoskeleton for both Ae. aegypti and Xenopsylla spp. Replicates in the maceration/extraction/detection protocol were increased in a stepwise fashion until a final 128 replicates were obtained. For dengue virus detection there was a 99% positivity rate and for Y. pestis detection there was a 95% positive detection rate. In the examination of both pathogens, there were no significant differences between qPCR instruments, days ran, time of day ran, or operators. © 2015 The Society for Vector Ecology.

    The aim of the present work was to investigate the microbiological, chemical, and sensory characteristics of red wine subjected to post-fermentation maceration that was extended to 90 days. For this purpose, the 'Aglianico di Taurasi' grape was used as a case study. The total yeast concentration increased until day 40 of maceration and decreased thereafter, whereas the concentration of lactic acid bacteria slightly increased. Dekkera/Brettanomyces spp. and acetic acid bacteria were not detected. The yeast community was composed of Saccharomyces cerevisiae, Zygosaccharomyces bisporus, Metschnikowia pulcherrima, Hanseniaspora guilliermondii, Hanseniaspora uvarum, Pichia guilliermondii, Aureobasidium pullulans and Debaryomyces carsonii. Nine S. cerevisiae strains were detected at high levels at different times of maceration. The results of all the conventional chemical analyses of the wines were in agreement with the regulations of commercial production and, interestingly, the changes in terms of concentration demonstrated the presence of yeast and LAB populations that were not only alive but also in a metabolically active state until day 90 of maceration. The alcohol and glycerol contents slightly increased until day 90. The concentrations of malic acid decreased, whereas those of lactic acid slightly increased throughout the maceration process. Furthermore, different durations of maceration resulted in significant differences in the total polyphenol content, which was higher at 40-50 days. The main phenolic compounds were benzoic and cinnamic acids and catechins. Interestingly, the highest ratio between (+)-catechin and (-)-epicatechin was found on day 40. In addition, the highest antioxidant activity was observed between days 40 and 50. The concentration of volatile organic compounds, which were mainly represented by alcohols, increased until the end of the maceration process. Sensory analysis revealed that samples that were subjected to maceration for a long

    The combustion behaviour of coal is significantly influenced by its rank and maceral and microlithotype compositions. Different macerals, due to their distinct and unique physical properties and chemical makeup, have different burning characteristics. This paper deals with the burning behaviour of coals of Indian origin by thermo gravimetric analysis (TGA) and in drop tube furnace (DTF) with particular emphasis on the role of macerals and their associations. Four coals of different rank and petrographic makeup, along with their two density fractions, with enriched vitrinite and inertinites, respectively,were studied in both TGA and DTF. The burnout behaviour was estimated from the chemical analyses of the char samples collected from the DTF. The burning characteristics of one of the coals deviate from the trend expected with the variations of rank. The behaviour of the density fractions in DTF was found to be different from that observed in TGA analyses. An attempt has been made to correlate the burnout with the petrographic macerals and microlithotypes present in the coals. The morphology of the residual chars indicates the contributions of the inertinites towards the formation of cenospheres and network types of reactive chars. The superior burning behaviour of the higher density inertinite-rich fractions over the raw coals and also some vitrinite-rich fractions indicate the better reactivity of the inertinites towards combustion.

    Reflectance FTIR microspectroscopy was used to investigate the chemical structure of the liptinite macerals, alginate, bituminite, sporinite, cutinite and resinite in bituminous coals of Carboniferous To Tertiary age. In comparison with the spectra of vitrinite in the same coals, the micro-FTIR spectra of liptinite macerals are characterized by stronger aliphatic CH{sub x} absorptions at 3000-2800 and 1460-1450 cm{sup -1}, less intense aromatic C=C ring stretching vibration and aromatic CH out of plane deformation at 1610-1560 and 900-700 cm{sup -1} respectively and various intense acid C=O group absorptions at 1740-1700 cm{sup -1}. The peaks at 1000-900 cm{sup -1} due to aliphatic CH{sub 2} wagging vibrations in olefins and at 730-720 cm{sup -1} due to CH{sub 2} rocking vibration in long chain aliphatic substances (CH{sub 2n}, n{ge}4), are characteristic of liptinite macerals. Collectively the micro-FTIR spectral characteristics indicate that liptinite is composed of greater numbers of long chain aliphatic, fewer aromatics and a broader range of oxygen-containing groups than other macerals. Marked differences exist in micro-FTIR spectra within the liptinite maceral group. Alginate has the strongest aliphatic and least aromatic absorptions followed by bituminite, resinite, cutinite and sporinite. Notable differences in micro-FTIR spectra of individual liptinite macerals, such as intensities and peak locations of aromatic C=C in alginate, C=O groups in bituminite and resinite and substituted aromatic CH and C-O-C groups in cutinite and sporinite, also exist, which are attributed to differences in depositional environments or biotaxonomy. 41 refs., 11 figs., 2 tabs.

    The role of fungus in the formation of coal macerals, both as a primary contributor in the form of a fungus fossil/maceral funginite, and in their role in degrading wood, thus producing degraded maceral forms, has been established. Fungus, in the course of breaking down the lignin and cellulose in wood, make the wood more digestible for grazers, such as arthropods. In turn, the remnants of the digested wood and anything else eaten but not completely digested are excreted and can be preserved intact; eaten by other fauna with a repeat of the cycle; or colonized by bacteria and/or coprophilous fungi with or without subsequent preservation. Ultimately, the coprolites can be preserved as a form of macrinite. ?? 2011 Elsevier B.V.

    A new system has been developed to perform automatically macerals and reflectance analysis of single-seam bituminous coals, improving the interlaboratory accuracy of these types of analyses. The system follows the same steps as the manual method, requiring a human operator for preparation of coal samples and system startup; then, sample scanning, microscope focusing and field centre analysis are fully automatic. The main and most innovative idea of this approach is to coordinate an expert system with an image processing system, using both reflectance and morphological information. In this way, the system tries to reproduce the analysis procedure followed by a human expert in petrography. (Author)

    Workforce planning is a resource to measure and compare current versus future workforce. Organised dentistry needs to focus on the benefits and the determinants and various systems of workforce planning together with the challenges, new trends and threats. The aim of the study was to identify data sources from countries relating to a selection of oral health indicators in a sample of FDI member countries. The potential for differences between developed and developing countries was also examined. A cross-sectional survey study was carried out among FDI member countries classified in developed and developing countries between October 2011 and January/February 2012. A questionnaire was developed addressing the availability of 40 selected indicators distributed in four domains. Mann-Whitney U-tests to identify differences between developed and developing countries and chi-square tests for the degree of information regularly available were carried out. There is an important lack of information about indicators relevant to oral health between FDI participating countries regardless of their level of economic development. Although not significant, the availability of indicators for developing countries showed higher variability and minimum values of zero for all domains. Surveys were the source of information more frequently reported. Standardised and reliable methodologies are needed to gather information for successful workforce planning. It is of utmost importance to increase the awareness and understanding of the member National Dental Associations regarding the role, basic elements, benefits, challenges, models and critical elements of an ideal workforce planning system.

    Full Text Available White grapes of Muscat Ottonel variety were treated enzymatically with maceration enzyme preparation and then fermented with selected yeast. These treatments resulted in an increase of the extraction of the compounds involved in wine aroma and of the must yield. Also an improvement of filterability and a decreasing of the sedimentation and clarification time were noticed. The enzymatic treatment presented a benefic effect on the dynamics of the alcoholic fermentation and the final wine composition. By using maceration enzymes, the wine aromatic intensity is emphasized, because the enzymatic preparation contains high concentrations of both glycosidase acting on the first stage of the enzymatic mechanism and the β-glucosidase acting on the second phase of enzyme mechanism able to release the aromatic constituents. These results are also closely related to the sensory analysis, which indicated that the glycosidase enzymatic treatment seemed to be effective for the improvement of the aroma of Muscat Ottonel wines.

    Full Text Available To investigate the phenolic and aroma composition of Malvazija istarska (Vitis vinifera L. white wines produced by an unconventional technology comprising prolonged maceration followed by maturation in wooden barrels, representative samples were subjected to analysis by UV/Vis spectrometry, high-performance liquid chromatography, and gas chromatography-mass spectrometry. When compared to standard wines, the investigated samples contained higher levels of dry extract, volatile acidity, lactic acid, phenols, colour intensity, antioxidant activity, majority of monoterpenes, C13-norisoprenoids, methanol, higher alcohols, ethyl acetate, branched-chain esters and esters of hydroxy and dicarboxylic acids, ethylphenols, furans, and acetals, as well as lower levels of malic acid, β-damascenone, straight-chain fatty acids, ethyl and acetate esters. It was estimated that maceration had a stronger influence on phenols, and maturation on volatile aromas. Despite different vintages and technological details, the investigated wines showed a relative homogeneity in the composition, representing a clear and distinctive type.

    In this study, investigations were made as to the effect of the maceral compositions and mineral matter content of Azdavay and Kurucasile coals on the coking property. Chemical and maceral analyses and coking properties were determined for the products of the float-sink procedure. The coking properties were established on the basis of free swelling index and Ruhr dilatometer tests. Maceral analyses showed that as the ash content of a coal containing both high and medium volatile matter increases, its effective maceral proportion decreases, and the coking property is affected in an unfavorable way.

    In our previous studies, injectable chitosan-based hydrogel (CH) was prepared and its application in surgery removal of tumor was studied. In this study, the antitumor and antimetastasis effects of the macerating solutions from CH were investigated. Our in vitro results showed that macerating solutions from CH significantly increased the proliferation of human normal liver L02 cells. In contrast, macerating solutions from CH showed significant inhibitory effects on the growth of human hepatoma Bel-7402 cells. In a mouse H22 tumor model, intraperitoneal injection of macerating solutions from CH decreased tumor growth and prevented tumor diffusion. Tumor weight was decreased dramatically in mice treated with macerating solutions from CH. The thymus index and spleen index were significantly increased by treatment with macerating solutions from CH. Administration of macerating solutions from CH also remarkably increased serum levels of TNF-α, IL-2, IFN-γ, and decreased serum VEGF content as compared with the control group treated with saline. The antimetastasis studies showed that the number of pulmonary nodules, pulmonary metastases index, and lymph nodes index were significantly decreased in experimental groups treated with macerating solutions from CH. This study provided more supporting data for the potential clinical application of CH after surgical removal of tumor.

    Full Text Available A low temperature enzyme maceration treatment was conducted during fermentation process of semi-dry cv. Premier blueberry wine. The aim of this study was to investigate the influence of maceration conditions on the wine aroma. As a pre-treatment, blueberry must was divided into 6 samples which were respectively treated by pectinase with 6 different maceration conditions at 6°C 1day, 6°C 2 days, 6°C 3 days, 16°C 1 day, 16°C 2 days and 16°C 3 days. After that wines were obtained by fermentation with Saccharomyces cerevisiae. Volatile compounds of wines were analyzed by GC-MS. Overall, the typical aroma compounds of semi-dry cv. Premier wines were constituted by three groups of organic compounds including esters, alcohols and fatty acids. Isoamyl acetate, ethyl caprylate, ethyl decanoate, 2-phenethanol and 3-methylbutanoic acid, which occupied 60% of the typical volatile aromatic compounds, all had higher Odor Activity Values (OAVs in 6°C 3 days than other conditions. Maceration temperature and time had a significant effect on concentration and varieties of wines aroma substances.

    More than one hundred and thirty coal seams and coaly layers occur in the Donets Basin (Donbas). Twenty-eight (52 samples) of them, ranging in age from Serpukhovian (Late Mississipian) to Gzhelian (Late Pennsylvanian), 33 clastics and three limestones were studied in terms of maceral composition, sulphur contents, and biomarker distribution. Diterpanes are used to estimate the contribution of different groups of plants and the height of the water table in the swamp; hopanes are a measure of bacterial activity in the peat; and steranes indicate the relative input of wood and algae. Stratigraphic trends in these parameters are discussed in relation to paleoenvironment, climatic changes, and eustacy. A tropical climate prevailed in the Donbas from Serpukhovian to Kasimovian times. Nevertheless, periods with drier and wetter conditions can be distinguished based on maceral and biomarker data. Relatively dry conditions are observed during Serpukhovian and Vereian times, whereas wetter climates with a maximum of coal deposition occurred during the (late) Bashkirian, most of the Moscovian, and the earliest Kasimovian. No economic coal seams are hosted in upper Kasimovian and Gzhelian deposits, a result of a change to an arid climate. Our data also suggest climatic changes during sequences of different order. For the second-order, third-order, and fourth-order sequences, relatively dry or wet conditions occurred during coal deposition in the lowstand systems tract, an intermediate climate during the transgressive systems tract and the maximum flooding, and a wet climate during the highstand systems tract. The results for high frequency sequences support the Cecil's paleoclimatic model: an intermediate paleoclimate during LST (sandstone and levee siltstone), a wet climate during early TST (coal), and a dry climate during late TST (limestone), MFS (claystone), and HST (deltaic siltstone). Coals deposited during maximum flooding periods are more enriched in C{sub 27

    The pyrolysis characteristics of Shendong Shangwan coal and its macerals concentrate were investigated using thermogravimetry (TG) coupled with mass spectrometry (MS).The evolved gases were analyzed online by MS spectroscopy.The results of TG/DTG (derivative thermogravimetry) show ths vitrinite concentrate has greater weight loss rate and higher volatile yield than the other two samples.More light hydrocarbons C1-C5 are released from the vitrinite concentrate than from the Shendong Shangwan coal and inertinite concentrated in the process of pyrolysis.Three samples have similar shape curves of evolved gases of C2-C5 with different intensities.When the pyrolysis temperature was lower than 418 ℃,the amount of C6H6 evolved in the process of pyrolysis of inertinite concentrated was higher than that of raw coal and vitrinite concentrate.As the temperature rising,the production rate of C6H6 increased.Below 672 ℃,C6H6 evolution rate of vitrinite concentrate was far greater than the other two samples; the main evolution temperature range of C7H8 was 400 ℃ to 700 ℃ for the three samples.The amount of H2 and H2O released first increased and then decreased with the temperature increase while more H2 released for pyrolysis of inertinite concentrated and more H2O released for the pyrolysis of vitrinite concentrate.

    Naturally macerated cuticles (NMC) and one synangium, representing medullosalean and marattialean tree-fern species, from two Carboniferous coalfields in Nova Scotia, Canada, are investigated. The samples were analyzed by infrared spectroscopy (FTIR), and by pyrolysis-gas chromatograph/mass spectrometry (py-Gc/Ms) techniques in search for chemical signatures that would help in developing a chemotaxonomic classification of Carboniferous fern species, assuming genetically dependent make-up of cuticles. FTIR-derived CH2/CH3 ratios, in conjunction with contributions from carboxyl groups, demonstrated a better potential for discriminating between medullosalean genera and species than molecular signatures obtained by py-Gc/Ms. However, the latter provided better data for differentiating medullosalean from marattialean tree ferns as a group. Changes in the chemical make-up of naturally macerated cuticles due to sample preparation are discussed. ?? 2001 Elsevier Science B.V. All rights reserved.

    Full Text Available The processing of boiled Prosopis africana endosperm for better utilization using ethanol-water mixtures was explored. Prosopis africana seeds were boiled for 5 h to softness and the endosperm fraction separated from the kernel (cotyledon and the hull. The endosperm was divided into five equal parts which were individually macerated in absolute (Abs ethanol, 80, 60 and 40% ethanol in water prior to sun-drying (32±2°C, 3 days. The fifth sample, which served as control, was left untreated with ethanol. The samples were ground using a hand milling machine and analyzed for the proximate composition, water and oil absorption capacities, foaming capacity and foam stability, bulk density, emulsion activity and stability, colour preference, texture preference and overall acceptability. The results revealed that treatment of the endosperm significantly affected the moisture, protein, fat, ash and carbohydrate contents; water and oil absorption capacities, foaming capacity and foam stability; and the sensory properties. The moisture and protein contents, oil absorption capacity, foam stability, appearance, texture and overall acceptability of endosperm treated with 40% ethanol in water differed significantly (p<0.05 from that treated with absolute ethanol. There was also significant (p<0.05 differences in moisture, protein and carbohydrate contents, oil absorption capacity and foam stability of the 40% ethanol in water treated endosperm and the control. Slightly above 40% ethanol in water (50-60% should be used to macerate Prosopis africana endosperm to reduce the cost of using absolute ethanol.

    A novel isolate, designated 6408J-67(T), was isolated from an air sample collected from Jeju Island, Republic of Korea. Its phenotypic, genotypic, and chemotaxonomic properties were compared with those of members of the family Microbacteriaceae. The Gram-positive, aerobic, motile rod formed light yellow, smooth, circular and convex colonies. Optimal growth occurred at 30°C and pH 7.0. 16S rRNA gene sequence data showed that the isolate was a novel member of the family Microbacteriaceae, with the highest sequence similarity (97.4%) to Labedella gwakjiensis KSW2-17(T) and less (10% of the total) were anteiso-C(15:0), iso-C(14:0), and iso-C(16:0). The strain also contained MK-13, MK-12, and MK-14 as the major menaquinones, as well as diphosphatidylglycerol, phosphatidylglycerol, and two unknown glycolipids. Its peptidoglycan structure was B1β with 2,4-diaminobutyric acid as a diamino acid. Mycolic acids were absent. The DNA G+C content was 68.3 mol%. Based on these phenotypic and genotypic findings, strain 6408J-67(T) represents a novel species of a new genus within the family Microbacteriaceae, for which the name Diaminobutyricimonas aerilata gen. nov., sp. nov. is proposed. The type strain is 6408J-67(T) (=KACC 15518(T) =NBRC 108726(T)).

  1. Study of Dynamics of Polyphenol Extraction During Traditional and Advanced Maceration Processes of the Babić Grape Variety

    Irena Budić-Leto

    2005-01-01

    Full Text Available The influence of different maceration techniques on the dynamics of polyphenol extraction during the maceration of the autochthonous Croatian grape Babić has been investigated. The process of wine production by maceration in traditional procedure and by maceration with advanced technique has been compared. During maceration, the dynamics of extraction of total anthocyanins, total phenols, low-molecular proanthocyanidins and high-molecular proanthocyanidins was determined. Mathematical models are proposed for each above mentioned and determined parameter. The models present the values under observation depending on treatment – traditional or modern. Time expressed in days is the input variable for both monitored models. Presented models indicate a significant positive correlation and strongly sustain the concept that the duration and procedure of maceration have considerable influence on the measured variables (R=0.83–0.98.

    Full Text Available The macerals, including fusinitic coal containing 72.20% inertinite and xyloid coal containing 91.43% huminite, were separated from Shengli lignite using an optical microscope, and their combustion reactivity was examined by thermogravimetric analysis. Several combustion parameters, including ignition and burnout indices, were analyzed, and the combustion kinetics of the samples were calculated by regression. Fusinitic coal presented a porous structure, while xyloid coal presented a compact structure. The specific surface area of fusinitic coal was 2.5 times larger than that of xyloid coal, and the light-off temperature of the former was higher than that of the latter. However, the overall combustion reactivity of fusinitic coal was better than that of xyloid coal. The combustion processes of fusinitic and xyloid coals can be accurately described by both the homogeneous model and the shrinking core model. The features of xyloid coal agree with the shrinking core model when its conversion rate is 10%–90%. The activation energy of fusinitic coal during combustion can be divided into three phases, with the middle phase featuring the highest energy. The activation energy of xyloid coal is lower than that of fusinitic coal in the light-off phase, which may explain the low light-off temperature of this coal.

The aim of this work was to investigate the changes in basic composition, anthocyanin profile and sensory properties of Blatina wines obtained with skin contact time from 4, 8, 12 to 16 days. Results indicate that longer period of maceration positively influenced the quality of Blatina wines. Blatina wines obtained by 12 or 16 days of maceration presented a significant increase of the dry extract, ash, total phenol and pH value. It was observed that the concentration of total and individual anthocyanins significantly increased reaching a maximum value within 12 days of the skin maceration. In all wines, the dominant anthocyanin was malvidin 3-glucoside. Best organoleptic properties were observed in the wines macerated for 16 days.

    This study demonstrates the significant lithologic variations that occur within the two shale samples from the Chittenango member of the Marcellus shale formation from western New York State in terms of mineralogical composition, type of lamination, pyrite occurrences and fossil content using thin section detailed description and field emission Scanning electron microscope (FESEM) with energy dispersive X-Ray Spectrum (EDX). This study is classified samples as laminated clayshale and fossiliferous carbonaceous shale. The most important detrital constituents of these shales are the clay mineral illite and chlorite, quartz, organic matter, carbonate mineral, and pyrite. The laminated clayshale has a lower amount of quartz and carbonate minerals than fossiliferous carbonaceous shale while it has a higher amount of clay minerals (chlorite and illite) and organic matter. FESEM analysis confirms the presence of chlorite and illite. The fossil content in the laminated clayshale is much lower than the fossiliferous carbonaceous shale. This can provide greater insights about variations in the depositional and environmental factors that influenced its deposition. This result can be compiled with the sufficient data to be helpful for designing the horizontal wells and placement of hydraulic fracturing in shale gas exploration and production.

    A range of factors needs to be taken into account for an ideal oral health workforce plan. The figures related to dentists, specialists, auxiliaries, practice patterns, undergraduate and continuing dental education, laws/regulations, the attitudes of oral health-care providers and the general trends affecting the practice patterns, work conditions and preferences of oral health-care providers are among such determinants. Thus, the aim of the present study was to gather such information from a sample of World Dental Federation (FDI) member countries with different characteristics. A cross-sectional survey study was carried out among a sample of FDI member countries between March 2, 2012 and March 27, 2012. A questionnaire was developed addressing some main determinants of oral health workforce, such as its structure, involvement of the public/private sector to provide oral health-care services, specialty services, dental schools, trends in workforce and compliance with oral health needs, and a descriptive analysis was performed. The countries were classified as developed and developing countries and Mann-Whitney U-tests and chi-square tests were used to identify potential significant differences (P > 0.05) between developed and developing countries. All data were processed in SPSS v.19. In the18 questionnaires processed, the median number of dentists (P = 0.005), dental practices (P = 0.002), hygienists (P = 0.005), technicians (P = 0.013) and graduates per year (P = 0.037) was higher in developed countries. Only 12.5% of developed and 22.2% of developing countries reported having optimal number of graduates per year. It was noted that 66.7% of developing countries had more regions lacking enough dentists to meet the demand (P = 0.050) and 77.8% lacked the necessary specialist care (P = 0.015). Although developing countries reported mostly an oversupply of dentists, regardless of the level of development most countries did not report an oversupply of specialists

    The mid Cretaceous represents one of the most prominent episodes of greenhouse climate with high atmospheric CO2 levels and much higher global temperatures than today. During this super-greenhouse, massive and widespread deposition of organic carbon occurred during several Oceanic Anoxic Events (OAEs). The OAEs are associated with prominent shifts in carbon isotopes and thus represent major disturbances of the ocean system and the global carbon cycle. As such, OAEs played a fundamental role in the evolution of Earth's climatic and biotic history. In the past, research on the dynamics of the mid Cretaceous greenhouse world was almost exclusively based on marine proxy data, while up to now, only few information is available on environmental dynamics and atmosphere/biosphere interactions in terrestrial settings. We investigate two sites (1258 and 1260), drilled approx. 350 km off Suriname at the Demerara Rise during ODP Leg 207, recovering late Albian to Santonian sediments. These black shales were deposited in a proximal position relative to the tropical South American mainland and provide the unique opportunity to link terrestrial environmental information with a wide range of marine paleoclimatic and paleoceanographic proxy data, thus allowing a direct land/sea correlation. Here, we show first results from our multi-parameter study along a stratigraphic splice from the mid Cenomanian to early Turonian, covering two exceptional paleoceanographic events, the OAE2 and the Mid Cenomanian Event (MCE). Our working strategy combines XRF-core scanning with microscopic investigation (maceral analysis), biomarker analysis and subsequently determination of isotopic composition of specific terrestrial organic compounds. Samples from the investigated interval cover a large range of total organic carbon (TOC) concentration, the organic material proves to be thermally immature. For the OAE2, values vary between 1.4 % TOC after the maximum isotope excursion and 23.3 % TOC within

    Full Text Available Effects of maceration duration on the phenolic composition and antioxidant capacity in red grapevine variety ‘Teran’ (Vitis vinifera L. was investigated in this study. Total phenolics, flavonoids, nonflavonoids, individual and total anthocyanins, vanillin index and antioxidant capacity measured by DPPH, ABST and FRAP methods were determined in ‘Teran’ wines during five different skin maceration periods (3, 7, 12, 17 and 21 days. Th e highest increase in the concentration of the most phenolic compounds and antioxidant capacity was obtained between the 3rd and 7th day of maceration. Prolonging the maceration from 7 to 21 days did not lead to significantly higher concentrations of total phenolics, flavonoids, nonflavonoids, total anthocyanins and antioxidant capacity measured with ABTS and FRAP methods. It is concluded that maceration duration of seven days is the most appropriate in order to obtain high concentrations of total phenolics and anthocyanins and high antioxidant capacity of ‘Teran’ wines.

    Hypericum perforatum L. (Hypericaceae), or St. John's Wort, is a well-known medicinal herb often associated with the treatment of anxiety and depression. Additionally, an oil macerate (Oleum Hyperici) of its flowering aerial parts is widely used in traditional medicine across the Balkans as a topical wound and ulcer salve. Other studies have shown that Oleum Hyperici reduces both wound size and healing time. Of its active constituents, the naphthodianthrone hypericin and phloroglucinol hyperforin are effective antibacterial compounds against various Gram-positive bacteria. However, hyperforin is unstable with light and heat, and thus should not be present in the light-aged oil macerate. Additionally, hypericin can cause phototoxic skin reactions if ingested or absorbed into the skin. Therefore, the established chemistry presents a paradox for this H. perforatum oil macerate: the hyperforin responsible for the antibacterial bioactivity should degrade in the sunlight as the traditional oil is prepared; alternately, if hypericin is present in established bioactive levels, then the oil macerate should cause photosensitivity, yet none is reported. In this research, various extracts of H. perforatum were compared to traditional oil macerates with regards to chemical composition and antibacterial activity (inhibition of growth, biofilm formation, and quorum sensing) vs. several strains of Staphylococcus aureus in order to better understand this traditional medicine. It was found that four Kosovar-crafted oil macerates were effective at inhibiting biofilm formation (MBIC50 active range of 0.004-0.016% v/v), exhibited moderate inhibition of quorum sensing (QSIC50 active range of 0.064-0.512% v/v), and contained detectable amounts of hyperforin, but not hypericin. Overall, levels of hypericin were much higher in the organic extracts, and these also exhibited more potent growth inhibitory activity. In conclusion, these data confirm that oil macerates employed in traditional

    Coal blends are increasingly utilised at power plants with significant savings and without breaking environment regulations. However, evidence of interaction among the coals requires the study of some parameters that affect combustion efficiency and related opacity of emissions. Actual plant data was available for the combustion of five families of binary blends (single coals and approximately 25%/75%, 50%/50% and 75%/25% blends) with variable contents of ash, volatiles and maceral composition. Size distribution of particles was determined for the coals fed to the plant boilers and the fly ashes, as well as for unburnt carbon in the latter. The almost homogeneously sized feed from different coals generates a size distribution in the fly ash where 250-{mu}m particles vary up to 1.29%, while particles smaller than 38 {mu}m vary between 21.74% and 62.41%. Unburnt carbon increases with size of ash particles from a maximum of 12.2% for fractions smaller than 38 {mu}m up to 73.9% for the fraction bigger than 150 {mu}m. Total content of unburnt carbon in the fly ash from combustion of coal blends show deviations from the expected weighted average of the constituent coals (K, L, T, P, F, S and N). These deviations are related to maceral composition and rank based on reflectance values. The smallest deviation is shown by the blend (T/P) with coals having low values of reflectance and homogeneity of maceral contents. Larger deviations were found for blends K/L, P/F and S/N with higher difference of rank and greater heterogeneity of maceral composition. The K/L, R/N and S/N blends show positive deviations with respect to the expected weighted average, that is, blending was detrimental to the combustion efficiency, while blend P-F showed an enhance of the combustion efficiency as measured by unburnt carbon in the fly ash. A 'reactive maceral index' introduced in this work plays a useful role. If a ratio of reactive maceral index is established for a binary blend as

    The effect of three enological techniques (low temperature prefermentative maceration, must freezing with dry ice, and the use of a maceration enzyme) on the extraction of anthocyanins and proanthocyanidins from must to wine during fermentative maceration was studied to determine the extent to which these compounds are extracted and to assess the changes on their qualitative composition due to enological technique applied. The results showed that the dry ice treatment led to wines with high color intensity and high anthocyanin content, the maximum rate of extraction being observed the first 6 days of fermentative maceration. Regarding the effect of the different techniques on the quantitative and qualitative composition of proanthocyanidins, only the dry ice treatment seemed to favor the extraction of high molecular weight skin proanthocyanidins. The low temperature prefermentative maceration treatment led to the highest concentration of proanthocyanidins at the moment of pressing; however, this treatment, contrary to expectations, led to wines with the highest content of seed-derived proanthocyanidins. The use of the maceration enzyme also increased the concentration of proanthocyanidins during all of the fermentative process, as compared to a control wine, although the increase was not only due to skin proanthocyanidins but also seed proanthocyanidins. We have demonstrated in this study that maceration enzymes also facilitate seed phenolic extraction.

    Humanist author J. G. Macer Szepsius (1530-after 1579) born in Szepsi, Upper Hungary (today Slovakia, Moldava and Bodvou) lived in Krakow and was a typical author of Latin occasional poetry. In a part of his work De vera gloria libellus (Booklet on the true glory) published in 1562 he deals with certain professions and criticizes them. Physicians are described as being garrulus (loquacious), mendicus (beggar), and having a big belly due to a luxury. The Physician doesn´t read books, is lazy and not characterized by his knowledge, but rather by ignorance, arrogance and pride. Physicians prescribe medications without knowing their effects. Such a criticism is surprising, because Macer Szepsius was probably closely related to medicine.

    Traditional maceration method was used for the extraction of polyphenols from chokeberry (Aronia melanocarpa) dried fruit, and the effects of several extraction parameters on the total phenolics and anthocyanins contents were studied. Various solvents, particle size, solid-solvent ratio and extraction time have been investigated as independent variables in two level factorial design. Among examined variables, time was not statistically important factor for the extraction of polyphenols. The optimal extraction conditions were maceration of 0.75mm size berries by 50% ethanol, with solid-solvent ratio of 1:20, and predicted values were 27.7mgGAE/g for total phenolics and 0.27% for total anthocyanins. Under selected conditions, the experimental total phenolics were 27.8mgGAE/g, and total anthocyanins were 0.27%, which is in agreement with the predicted values. In addition, a complementary quantitative analysis of individual phenolic compounds was performed using HPLC method. The study indicated that maceration was effective and simple technique for the extraction of bioactive compounds from chokeberry fruit.

    The low luminosity QSO (LLQSO) sample consists of type 1 active galactic nuclei (AGN) up to a redshift of z=0.06 in the Hamburg/ESO QSO survey. Its purpose is to study how the brightest AGN in the nearby universe evolve with respect to AGN activity and host properties as a function of redshift. We show that our sample lies well between the NUclei of GAlaxies (NUGA) sample and the Palomar Green (PG) QSO sample in terms of redshift, gas masses and luminosities and seems to connect them. The continuous growth in mass, luminosity and, linked to this, the AGN activity over the samples has either a statistical reason or is indicative of an evolutionary link between the different populations and might be related to cosmic downsizing. In addition, we present first results of our observations of three galaxies from our sample with the Submillimeter Array (SMA).

  17. Variations in coal maceral chemistry with rank advance in the German Creek and Moranbah Coal Measures of the Bowen Basin, Australia, using electron microprobe techniques

    Variations in the elemental composition of individual macerals in seams from the Permian German Creek and Moranbah Coal Measures in the Bowen Basin of Queensland have been studied over a wide range of coal ranks, using light-element electron microprobe techniques, to establish the coalification tracks of key macerals in a single coal-bearing interval from subbituminous through bituminous coal to anthracite. Vitrinite reflectance (Rv{sub max}) in the seams studied increases from 0.39% in the western part of the basin to over 3.5% in the east, apparently due to increases in burial depth. The study extends significantly the rank range covered by previous work on elemental analysis of individual macerals in the Gunnedah Basin, and provides a more useful basis than whole-coal analysis to evaluate the performance of coals in different utilisation processes. The microprobe results show that the carbon content of the telocollinite increases dramatically from 66% to 90% as the vitrinite reflectance of the coals (Rv{sub max}) increases from 0.39% to around 1.75%, but increases only slightly, from 90% to 91%, as Rv{sub max} increases from 1.75% to 3.52%. Oxygen decreases from around 26% to approximately 5% as Rv{sub max} increases from 0.39% to around 1.75%, and then decreases only very slightly into the anthracite range. The nitrogen content of the telocollinite in these coals also appears to decrease slightly with rank advance, and appears moreover to display a relatively abrupt drop at around 2% Rv{sub max}. This may be associated with the development of ammonium illite in the mineral matter. Organic sulphur in the telocollinite, on the other hand, seems to remain essentially constant with rank advance, at least in this particular succession. In contrast to vitrinite, fusinite and inertodetrinite have significantly higher but somewhat more constant carbon contents, varying only from around 81% to 93% C over the rank range studied. Oxygen in these macerals decreases from

    Recently, the prebiotic amino acid glycine has been found associated with natural jarosite samples from various locations around the world. Since the discovery of jarosite on Mars, extensive research focuses on linking this mineral group with possible detection of biosignatures in the geologic record on Earth and Mars. Multiple analytical methods, including extraction and mass spectrometry techniques have identified glycine and other biomolecules in jarosite samples. The jarosite end members jarosite (sensu stricto-potassium jarosite), natrojarosite (sodium jarosite), and ammoniojarosite (ammonium jarosite) have different thermodynamic stabilities, decompose at different rates, and have potentially different susceptibilities to substitution. Planetary protection issues have led to the suggestion that samples returned from Mars would need to be heat-treated before they could be analyzed on Earth. Although heat treatment of the samples would in theory destroy any potential biosignatures, valuable information can be obtained during thermal treatment by employing gravimetric techniques. The relationship between the thermodynamic stability of the jarosite end members and the effect that glycine has on the thermal decomposition behavior of each end member was investigated using thermal gravimetric analysis. Thermal gravimetric analysis has been suggested as a method capable of providing the heat treatment necessary to provide planetary protection while still providing useful information about the original state and composition of the potentially returned materials. Introducing glycine into the synthesis procedure of the potassium, sodium and ammonium jarosite end-member has elucidated the effects that glycine has on the thermal stability of the mineral group. Potassium jarosite appears to be the least susceptible to the effects of glycine, with the sodium and ammonium end members showing marked changes in thermal decomposition behavior and decomposition rates.

    The applicability of the reflectance micro-Fourier Transform infra-red spectroscopy (FTIR) technique for analyzing the distribution of functional groups in coal macerals is discussed. High quality of spectra, comparable to those obtained using other FTIR techniques (KBr pellet and transmission micro-FTIR), indicate this technique can be applied to characterizing functional groups under most conditions. The ease of sample preparation, the potential to analyze large intact samples, and ability to characterize organic matter in areas as small as 20 ??m are the main advantages of reflectance micro-FTIR. The quantitative aspects of reflectance micro-FTIR require further study. The examples from the coal seams of the Mist Mountain Formation, British Columbia show that at high volatile bituminous rank, reflectance micro-FTIR provides valuable information on the character of aliphatic chains of vitrinite and liptinite macerals. Because the character of aliphatic chains influences bond disassociation energies, such information is useful from a hydrocarbon generation viewpoint. In medium volatile bituminous coal liptinite macerals are usually not detectable but this technique can be used to study the degree of oxidation and reactivity of vitrinite and semifusinite.

    The use of oak products as a cheaper alternative to expensive wood barrels was recently permitted in Europe, which led to a continuous increase in the use of oak chips and staves in winemaking. The feasibility of the potentiometric electronic tongue as a tool for monitoring the effects of wine maceration with oak chips was evaluated. Four types of commercially available oak chips subjected to different thermal treatments and washing procedures and their mixture were studied. Ethanolic extracts of the chips were analysed using electrospray mass spectrometry and 28 phenolic and furanic compounds were identified. The electronic tongue comprising 22 potentiometric chemical sensors could distinguish artificial wine solutions and Cabernet Sauvignon wine macerated with different types of oak chips, quantify total and non-flavonoid phenolic content, as well as the concentrations of added oak chips. Using measurements at two pH levels, 3.2 and 6.5, improved the accuracy of quantification. Copyright © 2017 Elsevier Ltd. All rights reserved.

Despite of the wide use of the oil of Copaifera species, scientific works related to the study of its leaves are rarely found. In fact, processes for flavonoid extraction from C. langsdorffii leaves have not been studied yet leaving a wide field to be investigated. In this work, the 2(5-2 fractional factorial design was selected in order to study how the factors of a dynamic maceration process influence the responses of total flavonoids, total phenols, quercetrin and afzelin contents, and antioxidant activity in extracts from C. langsdorffii leaves. The results demonstrated that the significant factors studied were the drug load in extractor, the ethanol/water ratio and the stirring speed whereas the temperature and the extraction time were not significant. In conclusion, this study allowed visualizing which factors were considered the most important in copaiba leaves dynamic maceration and their effect in extract antioxidant activity. Furthermore, this technological study gives directions to optimize future extraction experiments from C. langsdorffii.

    We review the extraction into wine and evolution of major phenolic classes of sensory relevance. We present a historical background to highlight that previously established aspects of phenolic extraction and retention into red wine are still subjects of much research. We argue that management of the maceration length is one of the most determining factors in defining the proportion and chemical fate of phenolic compounds in wine. The extraction of anthocyanins, flavonols, flavan-3-ols, and oligomeric and polymeric proanthocyanidins (PAs) is discussed in the context of their individual extraction patterns but also with regard to their interaction with other wine components. The same approach is followed to present the sensory implications of phenolic and phenolic-derived compounds in wine. Overall, we conclude that the chemical diversity of phenolic compounds in grapes is further enhanced as soon as vacuolar and pulp components are released upon crushing, adding a variety of new sensory dimensions to the already present chemical diversity. Polymeric pigments formed by the covalent reaction of anthocyanin and PAs are good candidates to explain some of the observed sensory changes in the color, taste, and mouthfeel attributes of red wines during maceration and aging.

    We used for the first time a vascular casting material to take advantage of a simple tracing procedure and to isolate the peculiar features of acupuncture point injections. The polymer Mercox was injected into the skin of a dead mouse at acupuncture points along the bladder meridian lines. After a partial maceration of the whole body with a potassium-hydroperoxide solution, we anatomized it under a stereomicroscope to trace the injected Mercox. Many organs were checked to determine whether or not they contained some Mercox tracing. Connections between the injection sites along the acupuncture points were observed. Two to three layers of Mercox in a plate shape were found under the skin at the acupuncture points, and Mercox travelled throughout the adipose tissue, the fascia, and the parietal and visceral serous membranes inside the organ's parenchyma. The casting material Mercox used with a modified partial maceration procedure is a promising method for visualizing the routes of the meridian system and the primo vascular system. The routes for Mercox are different from those of the blood and lymphatic vessels.

    Full Text Available The objective of the present study was the isolation of a yeast strain, from citrus fruit peels, able to produce a polygalacturonase by submerged fermentation with maceration activity of raw cassava roots. Among 160 yeast strains isolated from citrus peels, one strain exhibited the strongest pectinolytic activity. This yeast was identified as Wickerhamomyces anomalus by 5.8S-ITS RFLP analysis and confirmed by amplification of the nucleotide sequence. The yeast produced a polygalacturonase (PG in Erlenmeyer shake flasks containing YNB, glucose, and citrus pectin. PG synthesis occurred during exponential growth phase, reaching 51 UE.mL-1 after 8 hours of fermentation. A growth yield (Yx/s of 0.43 gram of cell dry weight per gram of glucose consumed was obtained, and a maximal specific growth rate (µm of 0.346 h-1 was calculated. The microorganism was unable to assimilate sucrose, galacturonic acid, polygalacturonic acid, or citrus pectin, but it required glucose as carbon and energy source and polygalacturonic acid or citrus pectin as inducers of enzyme synthesis. The crude enzymatic extract of Wickerhamomyces anomalus showed macerating activity of raw cassava. This property is very important in the production of dehydrated mashed cassava, a product of regional interest in the province of Misiones, Argentina.

    During a study on the prevalence and diversity of campylobacteria in wild birds faecal samples from the city of Valdivia (southern Chile) 17 Gram-stain-negative, curved-rod-shaped isolates, were initially identified as Campylobacter lari by PCR-RFLP. Further identification by 16S rRNA sequence analysis revealed that they formed a distinct group in the genus Campylobacter. This unique position was confirmed by the results of analysis of rpoB, atpA and cpn60 gene sequences. The average nucleotide identity between the representative strain WBE38T and the type strain of the most closely related taxon C. larisubsp.concheus (LMG 11760) was 90.8 %. The oxidase and urease activity of the novel isolates enabled them to be phenotypically differentiated from species of the genus Campylobacter with validly published names. Therefore, on the basis of phenotypic, genetic and genomic characterizations, the results of this study clearly indicate that these strains represent a novel species within the genus Campylobacter, for which the name Campylobacter ornithocola sp. nov. is proposed, with the type strain WBE38T (=CECT 9147T=LMG 29815T).

    A medical compendium of "Melleus liquorphysicae artis" has survived under the name Alexander Hispanus; it is in codex Ms. 8769 of the Biblioteca nacional in Madrid. Therein a herbal from the 14th century is integrated. However, today people must think that we have one herbal and two authors: Alexander Hispanus and Henrik Harpestraeng (died 1244), a physician from Scandinavia. First of all, the parts of the medical compendium are presented. We do not know which parts originally belong to the medical compendium. The examination of many handwritings suggested that the discourses about consumption and dropsy were not originally included in the compendium; that seems certain. Further it was shown that probably Alexander Hispanus did not live after all and we must see him as a fictional person. Nevertheless we should not automatically regard Henrik Harpestraeng as the author of the herbal although it contains typical plants of the North like Angelica. The oldest codex of the herbal was probably written in Bavaria or Austria because it contains old Bavarian words. This handwriting can be seen as a piece of evidence that the knowledge about Angelica was spreading from the South. We should explore the connection with handwritings of the Macer, too. The herbal could be a Latin version of the Macer, in which the original verses are abandoned. An analysis of the medical plants made it clear that the herbal is probably directed to a male readership. Especially the chapter on Galganum elucidates that. In the 14th century Galganum was thought to have a contraceptive effect, but this was kept secret from women! All in all the structure of the herbal suggests a use as a kind of reference book that was not used daily though.

    The correct and consistent identification of the petrographic properties of coal is an important issue for researchers in the fields of mining and geology. As part of the study described in this paper, investigations concerning the application of artificial intelligence methods for the identification of the aforementioned characteristics were carried out. The methods in question were used to identify the maceral groups of coal, i.e. vitrinite, inertinite, and liptinite. Additionally, an attempt was made to identify some non-organic minerals. The analyses were performed using pattern recognition techniques (NN, kNN), as well as artificial neural network techniques (a multilayer perceptron - MLP). The classification process was carried out using microscopy images of polished sections of coals. A multidimensional feature space was defined, which made it possible to classify the discussed structures automatically, based on the methods of pattern recognition and algorithms of the artificial neural networks. Also, from the study we assessed the impact of the parameters for which the applied methods proved effective upon the final outcome of the classification procedure. The result of the analyses was a high percentage (over 97%) of correct classifications of maceral groups and mineral components. The paper discusses also an attempt to analyze particular macerals of the inertinite group. It was demonstrated that using artificial neural networks to this end makes it possible to classify the macerals properly in over 91% of cases. Thus, it was proved that artificial intelligence methods can be successfully applied for the identification of selected petrographic features of coal.

    We present accurate trigonometric parallaxes for 20 new members of the 25 pc white dwarf sample as part of the DENSE project (Discovery and Evalution of Nearby Stellar Embers, http://www.DenseProject.com). Previously, there were a total of 112 white dwarf systems with trigonometric parallaxes placing them within 25 pc and of these, 99 have trigonometric parallaxes known to better than 10%. Thus, the 20 new members presented in this work represent a 20% increase in the number of white dwarfs accurately known to be within 25 pc. In addition, we present updated parallaxes for seven known white dwarfs within 10 pc that have been observed as part of the ASPENS initiative (Astrometric Search for Planets Encircling Nearby Stars) to monitor nearby southern red and white dwarfs for astrometric perturbations from unseen companions. Including a few white dwarf companions and white dwarfs beyond 25 pc, we present a total of 33 trigonometric parallaxes. We perform atmospheric modeling for white dwarfs to determine physica...

    The increasing prominence of the construct of readiness to change in the field of substance abuse treatment has led to the development of instruments designed to assess the construct. We examined the psychometric properties of one such instrument, the Stages of Change Readiness and Treatment Eagerness Scale (SOCRATES), in a sample of treatment-seeking, active duty, U.S. military service members diagnosed with alcohol and/or drug dependence. A principal components analysis of the items was consistent with the tridimensional structure of the SOCRATES found among treatment-seeking civilians but resulted in a 14-item scale, as opposed to the 19-item version found for civilians. Normative data, in the form of means and decile rankings for the SOCRATES subscales, for substance-dependent military patients are provided to complement those available for civilian patients. Future research should examine the concurrent and predictive validity of the scale.

  18. Effects of skin maceration time on the phenolic and sensory characteristics of Bombino Nero rosé wines

    Full Text Available Rosé wines consumption has reached the highest level in present years and it is still an ongoing trend in several countries. Therefore, the production of rosé wines with improved sensory qualities and colour stability would be greatly appreciated. Today, although rosé wines are no longer considered to be less valuable than red and white ones, anyway, because of the past rosé’s reputation the scientific state of art lacks of specific studies concerning the effects of pre-fermentation maceration times on rosé wines. In this study, different pre fermentation maceration times (3, 6 and 8 h during production of original location certified and guaranteed rosé wine from Bombino Nero variety (Vitis vinifera L. were investigated. In all wines standard and specific wine chemical parameters, such as polyphenols, anthocyanins, flavonoids, hydroxycinnamoyl tartaric acids, volatile compounds and colour parameters were determined. A sensory descriptive analysis together with chemical analyses performed revealed that the maceration time significantly affected the aroma, the flavour and the colour of wines. The results showed that, although a longer maceration time is positively correlated to the colour stability of wine over time, however, a lengthener of the maceration is not favourable to enrich the wine with pleasant fruity and flowery aroma compounds, as both the gas chromatography and the sensory analyses showed. It was decided to perform the experimental winemaking processes in an actual winery instead of a laboratory in order to develop a practical winemaking management procedure directly usable for wine producers. The results obtained contribute to improve the knowledge about the importance of selecting the winemaking technique in order to elaborate high quality rosé wines.

    Detailed megascopic and microscopic petrographic analyses were conducted on samples of the Lower Kittanning seam from western Pennsylvania. Relationships were sought between the paleoenvironmental setting of the coal swamp and the vertical and lateral variability of lithotypes, maceral composition and vitrinite types. Megascopically, the four samples collected from the freshwater facies of the seam are similar in appearance and relative lithotype composition, and display no distinct vertical zonations. The sample from the marine-influenced central portion of the basin (PSOC-1340) possesses a marked vertical zonation into a bright lower zone and a dull upper zone. The lower zone is similar in appearance to the freswater samples. Detailed microscopic analyses revealed that the vertical zonation of PSOC-1340 is apparent in both the maceral and vitrinite type composition. No similar zonation is apparent in the microscopic analysis of the four freshwater facies samples. Similarities between the lower zone of PSOC-1340 and the whole seam of the freshwater samples are most apparent in the vitrinite-type analysis. The lower zone of PSOC-1340 and the whole seam from the freshwater facies are considered to be laterally equivalent coal types. The dull upper zone of PSOC-1340 is considered to have formed in response to a major change in the paleoenvironment of the swamp, probably a marine transgression. 49 references, 25 figures, 15 tables.

    The effects of enzymatic mash treatments on yield, turbidity, color, and polyphenolic content of cloudy apple juice were studied. Using HPLC-ESI-MS, cryptochlorogenic acid was identified in cv. Brettacher cloudy apple juice for the first time. Commercial pectolytic enzyme preparations with different levels of secondary protease activity were tested under both oxidative and nonoxidative conditions. Without the addition of ascorbic acid, oxidation substantially decreased chlorogenic acid, epicatechin, and procyanidin B2 contents due to enzymatic browning. The content of chlorogenic acid as the major polyphenolic compound was also influenced by the composition of pectolytic enzyme preparations because the presence of secondary protease activity resulted in a rise of chlorogenic acid. The latter effect was probably due to the inhibited protein-polyphenol interactions, which prevented binding of polyphenolic compounds to the matrix, thus increasing their antioxidative potential. The results obtained clearly demonstrate the advantage of the nonoxidative mash maceration for the production of cloud-stable apple juice with a high polyphenolic content, particularly in a premature processing campaign.

    The modification of Shenfu coals by a microwave treatment carried out under a hydrogen or a methane atmosphere,and the subsequent maceral separation by flotation,are described in this paper,The surface contact angle and the Zeta potential of the coal macerals were measured both with and without the treatment.The results show that the surface wettability ofSFF (Shenfu Fusain) and SFV (Shenfu Vitrain) can be changed by the microwave treatment.An increase in the difference in surface wettability of SFF and SFV causes in a subsequent increase in the enrichment of inertinite and vitrinite.The results of the Zeta potential measurements show that the surface potentials of SFF and SFV are also changed by the treatment.

    Full Text Available Modified cured vanilla was processed to vanilla extract by maceration method. The aim of this research were to optimize the method of maceration, type of vanilla bean with highest vanillin content, extraction solvent composition,and other variables that could optimize the vanillin content and characterize the extract from half dried cured vanilla. The optimation used response surface method with 22 factorial and 23 factorial. One step of maceration could extract vanillin (average 2.3 g/l much more than two steps maceration (average 2.1 g/l. Vanillin content of the half dried cured vanilla (average 0.98 g/l was higher than cured vanilla 1 and cured vanilla 2 (average 0.41 g/l and 0.32 g/l. The suitable ethanol-water composition for half dried cured vanilla was 7:3 (vanillin content 1.78 g/l. The first optimation was conducted with two variables maceration time and sucrose concentrations. The maximum vanillin content of the first optimation was 4.5 g/l at maceration time of15.9 days and sucrose concentration of 7.3 g. The second optimation used two variables: maceration time and glycerol concentrations. The maximum vanillin content of the second optimation was 3.8 g/l at maceration time of 22 days and glycerol concentration 19.9 ml. The third optimation process used three variables:maceration time, sucrose concentrations and glycerol concentrations. The maximum vanillin content of the third optimation was 3.4 g/l at maceration time of 12 days sucrose concentration of 7 g, and glycerol concentration 4.7 ml. The characteristic of vanilla extract resulted from half dried cured vanilla maceration were vanillin content (3.4-4.5 g/l, total acid (380-410 ml 0.1 N NaOH/l, total ash (1.3-3.4 g/l, total soluble ash (0.8-2.9 g/l, alkalinity of total ash (462.6-536.7, alkalinity of soluble ash (139.1-216.5, and lead number (4.5-4.6.

    Full Text Available During a two-year study, the effect of different grape mash maceration treatments (skin contact at 20 °C for 10, 20 and 30 h and cryomaceration (skin contact at 7 °C for 10, 20 and 30 h on the concentration of free and bound monoterpenes and total phenols in Malvazija istarska wine (the most spread white wine variety in Istria was monitored. Monoterpenic alcohols linalool, a-terpineol, citronellol, nerol and geraniol were determined by gas chromatography after isolation on octadecylsilica (C18 sorbent and elution with pentane/dichlorometane ratio of 2:1, while total phenols were determined spectrophotometrically with Folin-Ciocalteau reagent. Sensory evaluation of wines was performed using the Buxbaum method. The obtained results show that linalool and geraniol are the most abundant monoterpenes in Malvazija istarska, and that grape mash maceration treatments cause significant increase of free and bound monoterpene concentrations compared to those in control treatment wine obtained without maceration. The content of phenols, which are subject to oxidation, was found to be significantly lower in wines produced by cryomaceration treatments, while in those produced by maceration at 20 °C the concentration of total phenols increased proportionally with the duration of maceration, negatively influencing wine quality by causing higher colour intensity and bitter taste.

    Cell wall profiling technologies were used to follow compositional changes that occurred in the skins of grape berries (from two different ripeness levels) during fermentation and enzyme maceration. Multivariate data analysis showed that the fermentation process yielded cell walls enriched in hemicellulose components because pectin was solubilized (and removed) with a reduction as well as exposure of cell wall proteins usually embedded within the cell wall structure. The addition of enzymes caused even more depectination, and the enzymes unravelled the cell walls enabling better access to, and extraction of, all cell wall polymers. Overripe grapes had cell walls that were extensively hydrolyzed and depolymerized, probably by natural grape-tissue-ripening enzymes, and this enhanced the impact that the maceration enzymes had on the cell wall monosaccharide profile. The combination of the techniques that were used is an effective direct measurement of the hydrolysis actions of maceration enzymes on the cell walls of grape berry skin.

    Bovine tuberculosis (bTB), which is caused by Mycobacterium bovis and M. caprae, is a notifiable animal disease in Germany. Diagnostic procedure is based on a prescribed protocol that is published in the framework of German bTB legislation. In this protocol small sample volumes are used for DNA extraction followed by real-time PCR analyses. As mycobacteria tend to concentrate in granuloma and the infected tissue in early stages of infection does not necessarily show any visible lesions, it is likely that DNA extraction from only small tissue samples (20-40 mg) of a randomly chosen spot from the organ and following PCR testing may result in false negative results. In this study two DNA extraction methods were developed to process larger sample volumes to increase the detection sensitivity of mycobacterial DNA in animal tissue. The first extraction method is based on magnetic capture, in which specific capture oligonucleotides were utilized. These nucleotides are linked to magnetic particles and capture Mycobacterium-tuberculosis-complex (MTC) DNA released from 10 to 15 g of tissue material. In a second approach remaining sediments from the magnetic capture protocol were further processed with a less complex extraction protocol that can be used in daily routine diagnostics. A total number of 100 tissue samples from 34 cattle (n = 74) and 18 red deer (n = 26) were analyzed with the developed protocols and results were compared to the prescribed protocol. All three extraction methods yield reliable results by the real-time PCR analysis. The use of larger sample volume led to a sensitivity increase of DNA detection which was shown by the decrease of Ct-values. Furthermore five samples which were tested negative or questionable by the official extraction protocol were detected positive by real time PCR when the alternative extraction methods were used. By calculating the kappa index, the three extraction protocols resulted in a moderate (0.52; protocol 1 vs 3

    This work studies the effect of pulsed electric field (PEF) treatment at moderate and high field strengths (E=0.8kV/cm & 5kV/cm) prior and during alcoholic fermentation (AF) of red grapes on improving different parameters of pre-treated extracts: pH, °Brix, colour intensity (CI), total polyphenols content (TPI) of Cabernet Sauvignon red wine. Similar trends were observed for treating grapes using moderate and high electric field strength on the enhancement of CI and TPI of the wine after AF. The application of PEF using moderate strengths at different times during cold maceration (CM) (0, 2 and 4days) was more efficient for treatment during CM. The treatment during AF showed lower extraction rate compared to treating during CM and prior to AF. Our results clearly show that the best time for applying the PEF-treatment through the red fermentation is during the CM step.

    The effect of maceration process on the profile of phenolic compounds, organic acids composition and antioxidant activity of grape juices from new varieties of Vitis labrusca L. obtained in industrial scale was investigated. The extraction process presented a high yield without pressing the grapes. The use of a commercial pectinase resulted in an increase on extraction yield and procyanidins B1 and B2 concentrations and a decrease on turbidity and concentration of catechins. The combination of 60 °C and 3.0 mL 100 kg(-1) of enzyme resulted in the highest extraction of phenolic compounds, reducing the content of acetic acid. The juices presented high antioxidant activity, related to the great concentration of malvidin, cyanidin, catechin and caffeic, cinnamic and gallic acids. Among the bioactive compounds, the juices presented high concentration of procyanidin B1, caffeic acid and trans-resveratrol, with higher levels compared to those reported in the literature.

    Different strategies were adopted to achieve increases in color stability in Tempranillo wines: (i) addition of maceration enzymes directly to the must, (ii) addition of commercial mannoproteins to the must, and (iii) inoculation of must with yeast overexpressed of mannoproteins. The addition of enzymes favored color extraction, and the wines obtained presented higher values of wine color, color intensity, bisulfite-stable color, and visually enhanced color intensity. The enzyme hydrolytic activity produced an increase in the acid polysaccharide content and polyphenol index and yielded to wines with more astringency, tannin, and length. Added mannoproteins had clearer effects on the analyzed parameters than yeast. Contrary to what may be thought, mannoproteins did not maintain the extracted polyphenols in colloidal dispersion and neither ensured color stability. These compounds clearly modified the gustative structure of the wines, enhancing the sweetness and roundness.

    The effects of six maceration treatments on volatile aroma and phenol composition of Teran red wine were studied: standard maceration (control C), cold pre-fermentation maceration (CPM), saignée (S), pre-fermentation heating with extended maceration (PHT) or juice fermentation (PHP), and post-fermentation heating (POH). PHP wine contained the highest amounts of esters, fatty acids and anthocyanins, and the lowest content of other phenols. Alternative treatments decreased higher alcohols in relation to control C. CPM treatment lowered the extraction of seed tannins, exhibited the highest acetaldehyde, ethyl acetate and C6-compounds levels, and had increased ester levels in relation to control C. POH wine contained the highest concentration of total phenols, flavonoids, monomeric, oligomeric and polymeric flavanols, and color intensity and hue. S and PHT wines contained lower amount of total phenols, but higher than in C and CPM wines. The calculated Odor Activity Values were used to establish significant differences between the treatments.

    A study of the elemental composition of intimately associated coal macerals in the English Swallow Wood coal bed was conducted using a laser microprobe mass analyser, and indicated a similar trace and minor elemental chemistry in the vitrinite and cutinite and a different elemental signature in the fusinite. Three to six sites were analysed within each maceral during the study by laser micro mass spectrometry (LAMMS). Al, Ba, Ca, Cl, Cr, Dy, F, Fe, Ga, K, Li, Mg, Na, S, Si, Sr, Ti, V, and Y were detected by LAMMS in all three macerals but not necessarily at each site analysed. The signal intensities of major isotopic peaks were normalized to the signal intensity of the m z 85 peak (C7H) to determine the relative minor- and trace-element concentrations among the three dominant macerals. The vitrinite and the cutinite were depleted in Ba, Ca, Dy, Li, Mg, Sr, and Y relative to their concentrations observed in the fusinite. The cutinite was distinguished over vitrinite by less Ti, V, Cr and Ca, and K Ca $ ??1 (relative signal intensities). The fusinite, relative to the cutinite and vitrinite, was relatively depleted in Cr, Sc, Ti, and V. The fusinite, as compared with both the cutinite and vitrinite, was relatively enriched in Ba, Ca, Dy, Li, Mg, Sr, and Y, and also showed the most intense m z 64, 65, 66 signals (possibly S2+, HS2+, H2S2+, respectively). The LAMMS data indicate a common source for most elements and selective loss from the maceral precursors in the peat or entrapment of certain elements as mineral matter, most likely during the peat stage or during early diagenesis. The relatively high amounts of Ba, Ca, Dy, Li, Mg, Sr, and Y in the fusinite are consistent with micron and submicron mineral-matter inclusions such as carbonates and Ca-Al phosphates (probably crandallite group minerals). Mineralogical data on the whole coal, the LAMMS chemistry of the vitrinite and cutinite, and scanning electron microscopy/energy dispersive X-ray analysis (SEM/EDAX) of

    Apoplexia is not only one of the leading causes of death, but also a major contributor to disability in the aged. Population based prevalence rates, though being of basic importance for describing and planning health care structures, are sparse in the Federal Republic of Germany. We estimated the prevalence of apoplexia and transient ischemic attack (TIA). Data were gathered from a 5% representative random sample of insured of the local statuatory health insurance (AOK) in Dortmund, Germany (n = 7447). Cases were identified by the diagnosis on medical certificates, being further validated internally by other patient data. The rough prevalence rate was 0.86% (m 0.79%, f 0.93%) for apoplexia and 0.6% (m 0.4%, f 0.78%) for TIA. Adjusted for age and sex to the whole population of the FRG (excluding the former German Democratic Republic) the prevalence rate was 0.75% (m 0.8%, f 0.7%) for apoplexia and 0.52% (m 0.41%, f 0.63%) for TIA. 65% of the insured with apoplexia were 70 years and older; their average age was 71.7 years. The average age of the insured with TIA was 65.4 years. Prevalence rates for apoplexia increased continuously by age and were higher for men than for women in all age groups. Prevalence rates for TIA also increased with age, but under men only to the age of 70; after that-simultaneous to a steep rise of apoplexia prevalence-no more TIAs were noticed.

    The Vitis vinifera L. cv Graciano is often used as an integral component of Rioja wines because it is considered to contribute significantly to the quality of Tempranillo based wines. The aim of this work was to determine the effect of the incorporation of the Graciano variety on the colour and pigment composition of Tempranillo based wine and to evaluate the possible differences between blending Tempranillo with Graciano varietal wine (W wine) in contrast to a wine obtained by mixing these two grape varieties in the prefermentative maceration step (M wine). Results indicated that pigment extraction and retention in M wine was higher than in Tempranillo (T) wine. Colour differences (DeltaE(ab)(*)) between wines at the end of the study (after 12 months in bottles) were detectable by the human eye (DeltaE(ab)(*) > or = 3) in all cases except for T and W. These wines have indistinguishable colours even when using analytical methods (DeltaE(ab)(*) red) than Graciano (G) and M (more blue-red). PCA allowed the colour and composition analytical data to be reduced to a small number of principal components that could separate successfully between T and G wines and between the different steps of the winemaking process.

    The influence of high hydrostatic pressure (HHP) processing in parallel with oak chip maceration on the physicochemical and sensory properties of a young red wine was investigated preliminarily. Wines were treated by HHP at 250, 450 and 650MPa for up to 45min and French oak chips (5g/L) were added. HHP enhanced the extraction of phenolics from oak chips. The phenolic contents and antioxidant activity of the wine increased after HHP processing in the presence of oak chips. Meanwhile, the anthocyanin content and wine color intensity decreased in the first 5min of pressure treatment and then increased gradually. The multivariate analysis revealed that "pressure holding time" was the key factor affecting wine physicochemical characteristics during HHP processing in the presence of oak chips. Furthermore, oak chip maceration with and without HHP processing weakened the intensities of several sensory attributes and provided the wine with an artificial taste.

    Subject of the research were coal samples from the seams of Orzesze and Ruda beds from "Pniówek" coal mine. All samples represent methabituminous coal B, which present high vitrinite content (V mmf > 60%). Optical character of vitrinite from all analyzed coal samples is biaxial negative and it is characterized by low differentiation of bireflectance. The experiments have shown that the coal rank of investigated samples is generally decreasing with increasing both depth of coal seams and the distance between sampling point and the Carboniferous roof. It may suggests inversion of coalification. Specific types of macerals, typical for thermally metamorphosed coals have been found for all analysed coal samples. It was found, presence of such components like: fluorescing bituminous substance (FBS) filling of cellular spaces in semifusinite, fusinite, and funginite; pseudomorphs after megaspores exhibiting strong bireflectance, and anisotropic semifusinite. Petrographic components with a structure similar to structure of coke and pyrolytic carbon were observed rarely. Presence of colotelinite grains which are visible darker, impregnated with bituminous substance and exhibiting weak fluorescence may be related with influence of temperature on coal. Carbonates occur as filling of cellular spaces in semifusinite, in examined coal samples and there are the effect of thermal alteration of coal. Przedmiotem badań były próbki węgla z pokładów warstw orzeskich i rudzkich KWK Pniówek. Badane próbki reprezentują węgiel średniouwęglony typu B (metabitumiczny), wysokowitrynitowy. Stwierdzono, że witrynit z badanych próbek ma dwuosiowy ujemny charakter optyczny i wykazuje małe zróżnicowanie w wartościach dwójodbicia. Przeprowadzone badania wykazały, że stopień uwęglenia badanych próbek generalnie maleje wraz ze wzrostem głębokości występowania pokładów węgla oraz ze wzrostem odległości miejsca opróbowania od stropu karbonu co może wskazywać na

    Tithonia diversifolia belongs to the Asteraceae family. The leaves of T. diversifolia have been studied lately because of the presence of tagitinin C. Looking for an easy and inexpensive method to extract tagitinin C from T. diversifolia leaves, this work aims to conduct a screening to evaluate the influence of different experimental factors using the dynamic maceration and ultrasound-assisted extraction methods with 2(3) factorial design based on response surface methodology in enhancing this chemical marker extraction. The experimental factors were: extraction time (ET) of 30 and 60 minutes, solid: liquid ratio (SLR) of 5 and 10 grams/grams and ethanolic strength (ES) 48 and 96% (w/w). The experiments were done tripled. The content of tagitinin C in each produced extract was quantified by HPLC method. The highest concentrations of tagitinin C obtained under the experimental design were 0.53 mg/mL and 0.71 mg/mL, respectively for dynamic maceration (DM) and ultrasound-assisted extraction (UAE) from Tithonia diversifolia powdered leaves. For the UAE method, the main parameter for higher contents of tagitinin C was the solid: liquid ratio, followed by the ethanolic strength, and the extraction time was not significant for this method. As for the DM method, all the parameters (SLR, ES, and ET) were significant for a higher content of tagitinin C. Based on the obtained results, it was revealed that the ultrasound-assisted extraction was more effective than dynamic maceration for tagitinin C extraction from T. diversifolia powdered leaves. Tithonia diversifolia leaves possess tagitinin C, a sesquiterpene lactone, as an important secondary metabolite with several biological activities, such as antimalarial, gastroprotective, chemotherapeutic adjuvants, and toxic activities.Ultrasound-assisted extraction was more effective to obtain higher levels of tagitinin C when compared with dynamic maceration extraction.Factorial design can be employed as a screening tool to find

    cross sections and many are characterized by dense (probably oxidized) rims. The orientation and amounts of void space and mineralization of resin rodlets in coal have resulted in much confusion in their recognition and classification. The resin rodlets are petrographically recognized as sclerotinites of the inertinite maceral group. We here propose that resin rodlets be assigned to the maceral variety of sclerotinites termed "resino-sclerotinite" because of their presumable resinous origin. Other investigators have confused some fusinitized resin rodlets with fungal masses, which have different morphological properties and which probably have different chemical properties. We here propose that such fungal masses be assigned to the maceral variety of sclerotinites termed "fungo-sclerotinite.". The sclerenchyma strands examined in our study are cellular, thick-walled, and crescent-shaped in cross section. They exhibit high reflectance and high relief and belong to semifusinite and fusinite of the inertinite maceral group. Sclerenchyma strands are commonly associated with resin canals in Medullosa and related seed-fern genera, which are common in coal balls of the Illinois basin. We here propose adoption of the maceral varietal terms "sclerenchymo-fusinite" and "sclerenchymo-semifusinite" for these bodies. The woody splinters in the Pomeroy coal bed are cellular and thin-walled and have scattered pits as much as a few microns in diameter. They are dark brown to black in transmitted light and commonly have a lower reflectance than the resino-sclerotinite and sclerenchymo-fusinite of the Pomeroy coal. The woody splinters belong to semifusinite and fusinite of the inertinite maceral group. The maceral varietal terms "xylemo-semifusinite" and "xylemo-fusinite" are here proposed for these bodies. Elemental chemical data for the resin rodlets of the Pomeroy coal bed of the central Appalachian basin indicate that resin rodlets have significantly lower atomic H/C and O/C ratio

    Recent increases in oil price further strengthen the argument that coal and coal products will play an increasingly important role in fulfilling the energy needs of our society. Coal is an aggregate of heterogeneous substances composed of organic (macerals) and inorganic (minerals) materials. The objective of this review was to assess whether some chemical parameters in coal play a role in producing environmental health problems. Basic properties of coal--such as chemical forms of the organic materials, structure, compositions of minerals--vary from one coal mine region to another as well as from coals of different ranks. Most importantly, changes in chemical properties of coals due to exposure to air and humidity after mining--a dynamic process--significantly affect toxicity attributed to coal and environmental fate. Although coal is an extremely complex and heterogeneous material, the fundamental properties of coal responsible for environmental and adverse health problems are probably related to the same inducing components of coal. For instance, oxidation of pyrite (FeS2) in the coal forms iron sulfate and sulfuric acid, which produces occupational lung diseases (e.g., pneumoconiosis) and other environmental problems (e.g., acid mine drainage and acid rain). Calcite (CaCO3) contained in certain coals alters the end products of pyrite oxidation, which may make these coals less toxic to human inhalation and less hazardous to environmental pollution. Finally, knowledge gained on understanding of the chemical properties of coals is illustrated to apply for prediction of toxicity due to coal possibly before large-scale mining and prevention of occupational lung disease during mining.

    Full Text Available The influence of different grape mash maceration treatments on the varietal and secondary aroma profiles of wines produced from an aromatic red grape variety, Muškat ruža porečki, have been investigated. Two essentially different techniques were applied, fermentative maceration at room temperature and prefermentative cryomaceration, both in durations of one, three and five days. Generally, higher concentrations of free and bound varietal aroma compounds were found in wines obtained by maceration at room temperature in relation to cryomaceration. Regarding the effect of the duration of maceration, the highest concentrations were determined in wines obtained by three-day maceration treatments, in both fermentative and cryomaceration treatments. Secondary aroma compounds followed a less uniform pattern. The compounds with the highest odour unit values in all investigated wines were linalool, citronellol, geraniol, β-damascenone, β-ionone, isoamyl alcohol, 2-phenylethanol, ethyl hexanoate, ethyl octanoate, isoamyl acetate, ethyl acetate, and diethyl succinate. It has been shown that Muškat ruža porečki is an aromatic variety, producing wines with notable monoterpenol fraction, which are characterized by a typical varietal Muscat aroma with a dominant rose odour accompanied by red fruit nuances. Sensorially, longer maceration treatments improved odour and overall wine quality, together with the intensity and recognisability of varietal Muscat aroma, while short-term cryomaceration emerged as a preferable technique for the production of light rosé wines with pronounced Muscat aroma and low phenolic content. The presented maceration techniques were shown to be applicable for the production of different types of Muškat ruža porečki rosé and red wines.

    The exact function of type III secretion system in some phytopathogenes including Pectobacterium carotovorum subsp. atrosepticum (Pca) is not understood and is a matter of debate. The aim of this study were to determine specific effect of type III secretion system on potato tubers and to reveal the connection of this system with potato resistant genes such as PR-3. A Pca hrpW fragment was subcloned into a low-copy-number cloning vector (pZH448). The resulting plasmid (pAS19) was then conjugated into the wild-type and mutant strains of Pca by type III secretion system. The virulence property of different Pca strains was studied and the influence of over expression of hrpW on maceration activity was also investigated. Furthermore, the effect of mentioned mutation on the maceration of carrot-root was evaluated. Finally, using real-time PCR, the copy-number of PR-3 gene in potato tuber tissue was assessed. In conclusion, for type III secretion system mutant strains, in contrast with the wild-type, the maceration amount of potato tuber tissue decreased after over expression of hrpW while inoculation of tubers by mutants, increased this amount. In the case of potato, HrpN and DspE proteins appeared to be avirulent factors. Compared with the wild-type strains, Pca nominated mutants significantly reduced potato PR-3 expression thus, PR-3 expression level in potato tuber tissue in answer to infiltration by Pca, depends on functional type III secretion system in the bacterium.

    In order to provide technical support for the production of high-aroma quality wine in Gansu Hexi Corridor, the volatile compounds of Cabernet Gernischt red wine were analyzed by Headspace Solid-Phase Microextraction coupled with Gas Chromatography Mass Spectrometry, three maceration enzymes (EX-V, EX and HC), two yeast strains (BDX and D254) were used to prepare samples respectively and the volatile compounds of samples were compared and analyzed. The results showed that 75 compounds were identified in Cabernet Gernischt red wine, in which esters, alcohols, acids, aldehydes, ketones and terpenes were the major compounds;56、46 and 44 compounds were identified in samples added with EX, EX-V and HC maceration enzymes respectively, while 44 and 50 compounds were identified in fermented wine by D254 and BDX yeasts. The total concentration of volatile compounds in EX-V an d D254 samples was significantly higher than EX、HC and BDX samples, the differences of aroma compounds among Cabernet Gernischt wine fermented by different maceration enzymes and yeast strains were not obvious, while the trace aroma compounds were significantly different. The aroma contribution of compounds depends on odor activity value, i.e., OAV (concentration:the threshold value). According to OAVs, ethyl acetate, ethyl butyrate, isoamyl acetate, ethyl hexanoate, ethyl caprylate , ethyl caprate, Hexanol, phenethyl alcohol, amyl alcohol contribute much to main aroma compounds of Cabernet Gernischt red wine. It was generally recognized that aroma substances could contribute to the overall aroma when its concentration reached at 20%of threshold (OAV>0.2), and 20 compounds were identified as OAV>0.2 in the tested Cabernet Gernischt red wine, β-damascenone and geraniol could provide lemon, orange and other fruit flavor, phenethyl alcohol gived flavor of rose to wine, hexanol gived grass to wine , ethyl butyrate, isoamyl acetate, ethyl hexanoate and ethyl caprylate gived flavor of pear, banana

    The objective of the study was the estimation of the ultrasound-assisted preliminary maceration effect on the efficiency of essential oil distillation and on its qualitative and quantitative composition. The experiment included analyses on three herbal materials, i.e. peppermint leaves (Mentha piperita L.), marjoram herb (Origanum majorana L.), and chamomile flowers (Chamomilla recutita (L.) Rauschert). The study showed that the application of preliminary water maceration of raw material, augmented with ultrasounds, had a statistically significant increasing effect on the amount of oil distilled, in the case of mint leaf from 1.32% to 1.46% v/w, and in the case of marjoram herb from 1.13% to 1.27% v/w. In the case of chamomile flowers no significant effect of ultrasound on the amount of oil obtained was observed. Generally, comparing the composition of essential oils obtained in the experiments with the requirements of the relevant standards no unfavourable effect of the distillation augmenting techniques applied was noted. Therefore, it should be expected that the studied distillates of volatile fractions will have the desired biological activity. Copyright © 2014 Elsevier B.V. All rights reserved.

    The production of cellulose- (CEL), xylan- (XYL), and pectin-degrading enzymes (PEC) by a koji mold, Aspergillus oryzae, was studied, and their contributions to the maceration of the rice endosperm cell wall were investigated with regard to the utilization of available rice in the sake mash. The sake koji mold showed higher CEL and XYL productivities, whereas the miso and soy sauce koji molds showed higher PEC productivity. Statistical analyses indicated that CEL and XYL contribute predominantly and synergistically to the maceration of the rice endosperm cell wall. A. oryzae produced at least three kinds of CEL (Cel-1, 2, 3) and two kinds of XYL (Xyl-1, 2) when cultured in a wheat bran medium. In the solid-state culture, the production of Cel-3 and Xyl-2 was markedly stimulated by decreasing the moisture content of the solid substrate, although the production levels of Cel-1 and Xyl-1 were almost the same. These data suggest that the production of Cel-3 and Xyl-2 is strongly influenced by culture conditions, and that water activity is one of the dominant factors in the regulation of their production.

    The influence of cold maceration time on the non-anthocyanidin phenols of Merlot wine was analyzed by HPLC-MS. The results showed that the non-anthocyanidin phenols accumulated rapidly during the early stage of alcoholic fermentation after cold maceration for 16 hours. Compared with cold maceration for 7 days, treatment of cold maceration for 16 hours could improve the content of hydroxylcinnamic acids significantly. Treatment of cold maceration for 7 days could increase the stilbenes content significantly during the late stage of brewing. The cold maceration time had less influence on the p-Hydroxybenzoic acid, the flavonol , the flavan-3-ols and the total content of non-anthocyanidin phenols.%  利用高效液相色谱-质谱联用(HPLC-MS)技术对美乐葡萄酒中的非花色苷酚类物质进行分析,研究了不同冷浸渍时间对非花色苷酚类物质的影响。结果表明,冷浸渍16 h可使各非花色苷酚类物质在酒精发酵初期迅速积累,并显著提高了羟基肉桂酸类物质的含量,而冷浸渍7 d则可以在酿造后期显著提高芪类物质的含量,但冷浸渍时间对羟基苯甲酸、黄酮醇和黄烷-3-醇类物质的含量以及非花色苷酚类物质总含量影响不显著。

    2017-01-01

    Full Text Available The Greek traditional grape marc distillate Tsipouro was subjected to accelerated aging, using wooden chips from acacia, cherry, chestnut and oak wood. The processes included treatments under static maceration and ultrasonication and the evolution of the total polyphenol concentration was monitored over a period of 30 days. During this period, leaching of polyphenols from the chips into the distillate was found to obey first-order kinetics, but no statistical differences were shown between the two treatments regarding the enrichment of the liquid in polyphenolic substances. The determination of the antioxidant activity demonstrated that aging with chestnut chips may provide Tsipouro with particularly strong radical scavenging and reducing effects, highlighting its importance as a material that could be used to turn distillates into foods with functional properties.

    1982-01-01

    The initial reaction of components of the craniofacial skeleton of a macerated human skull was studied after high-pull headgear traction. The applied forces were increased step by step from 0.5 N to 3.25 N per side (1N = 100 grams). Laser holography was used for measuring displacements in three dimensions in seventeen indicator points on the skull. These points were located near sutures or on the outer surface of individual bones. The skull was observed from the right frontal and from the left lateral side. Results indicate that displacements range from 0 micrometer to 17.0 micrometers, depending on force magnitude and on the location of the observed point. Individual components of the craniofacial skeleton were mostly displaced in a horizontal backward direction when the skull was viewed from the frontal aspect. Various compression and shearing patterns were observed in the craniofacial sutures, apparently depending on their spatial locations and intersutural surface morphology.

    酒西盆地主力烃源岩为下白垩统下沟组和赤金堡组暗色半深湖相-深湖相的白云质泥岩和泥质白云岩,是典型的湖相碳酸盐岩烃源岩.通过对酒西盆地下白垩统二百多块湖相碳酸盐岩烃源岩详细的有机岩石学研究,解剖了湖相碳酸盐岩烃源岩中有机质的赋存形式,揭示了藻纹层为有机质纹层的主要发育形式,其与富泥晶白云石纹层和富粘土纹层构成湖相碳酸盐岩烃源岩特有的“三元式纹层”沉积结构,系统总结了各显微组分的光性、成因、生烃性及分布规律,提出了以全岩和干酪根为基础的湖相碳酸盐岩有机显微组分分类方案,首次鉴定出对酒西盆地油气有贡献的主要生烃组分为腐泥无定形体、腐殖无定形体以及浮游藻类体、孢粉体、壳屑体五种有机显微组分.%The typical lacustrine carbonate source rocks include dark dolomitic mudstone and argillaceous dolomite of Chijinpu ami Xiagou formations of Lower Cretaceous, which represent major petroleum source rocks in Jiuxi basin, NW China. Over 200 samples were selected from Lower Cretaceous lacustrine carbonate source rocks in Jiuxi basin for a detailed organic petrology analysis. Organic laminae has been recognized which is mainly algal laminae and "three-layer" structure is unique for lacustrine carbonate source rocks, which consists of algal laminae, micrite dolomite laminae and clay laminae. A petrographic classification of macerals in lacustrine carbonate source rocks has been suggested on the basis of whole rock and kerogen analysis. The discussion has also been carried out on the origins, the optical properities, hydrocarbon generation potential and geological distribution of macerals in these lacustrine carbonate source rocks. Five major hydrocarbon-generating macerals contributed to petroleum resources are firstly identified which are sapropelic amorphogen, humic amorphogen, alginite, sporopollenite and

    The paper describes the derivatization of hydroxyl groups in coals and coal macerals by stannylation. Stannylation of a range of phenolic compounds with Me{sub 3}SnCl, Bu{sub 3}SnCl and (Bu{sub 3}Sn){sub 2}O (TMTO) was carried out under both microwave-driven and conventional conditions. The degree of Stannylation was influenced by the steric environment of the OH group, implying that stannylation in comparison with, say trimethylsilylation of OH groups could help to map the steric environments of phenolic groups in coals. Good maceral separations of Creswell coal and acceptable separation of Cottonwood coal were achieved. The whole coals and the macerals were stannylated with TBTO under microwave-enhanced conditions and the products were examined by {sup 119}Sn MAS n.m.r. and X-ray photoelectron spectroscopy. The reaction was confined to surface regions. Differences were found in the behaviour of the macerals. The crystal and molecular structures of the trimethylstannyl derivative of 2,6-diphenylphenol were determined, to establish the validity of the claim to have stannylated model compounds. Molecular parameters were compared with related systems. 18 refs., 3 figs., 5 tabs.

    Full Text Available Objective: The purpose of this study was to determine the bacterial contamination of toothbrushes in family members. Materials and Methods: One hundred and two healthy subjects were included in this descriptive study. Every individual was examined clinically and microbiologically using the CPITN index and collecting subgingival plaque samples. Each participant received a toothbrush for home use and after one month they returned it to the investigators. All toothbrushes were cultured to determine the presence of periodontopathic bacteria and enteric rods. Wilkoxon signed rank test and t student test (P d"0.05 were used to compare differences in the subgingival microbiota and toothbrush contamination and CPITN index among family members. Results: A high proportion of toothbrushes resulted highly contaminated with enteric rods (P d"0.001 compared to the subgingival environment where periodontopathic bacteria were more prevalent. The most frequent microorganisms found in toothbrushes used by parents and children for one month were Enterobacteriaceae, Pseudomonadaceae species (>50% and Fusobacterium spp (30%. Conclusions: High levels of enteric rods were commonly detected in toothbrushes used for 1 month among members of the families. These opportunistic organisms may have an important role in oral infections including gingivitis and periodontitis. Monthly replacement or disinfection of the toothbrush can reduce the risk of bacterial transmission/translocation and thus diminish the incidence of biofilm associated oral diseases.

    Full Text Available Brazil has one of the world's largest biodiversity in flora and a plant that has attracted attention is the Endopleura uchi (Huber Cuatrec., Humiriaceae, which is native of the Brazilian Amazon. Among the many popular uses, this species is utilized in the treatment of woman's genito urinary tract affections and also as anti-inflammatory. It is believed that their actions derive from the major constituent, bergenin. The objective of this work was to study the Endopleura uchi barks extraction using the dynamic maceration method and the effects of the extraction time, drug to solvent ratio and temperature. A Box-Behnken design was applied to study the influence of these factors and the respective response surfaces. The extract characterization was made by determination of its antioxidant activity by DPPH; total polyphenol content and bergenin content. In general, the extracts showed good antioxidant activity, with the IC50 ranging from 4.02 to 5.87 µg/mL. The polyphenol content ranged from 31.89 to 47.82%. High levels of chemical markers are observed in all extracts, with average bergenin content of 35.58%. The result showed that the multivariate study of extraction is key step in the development and standardization of extracts Endopleura uchi.

  1. Evaluation of intrusive mechanics of the type "segmented arch" on a macerated human skull using the laser reflection technique and holographic interferometry.

    1986-03-01

    Twelve different systems of intrusion, based on the principle of the "segmented arch," were evaluated on a macerated human skull. The number of teeth involved in the anterior unit and the location of the application points of intrusive force were considered to be variables. Initial displacements of the anterior teeth after loading were registered by means of the laser reflection technique and double exposure holographic recordings. An attempt was made to define "this" intrusive system, achieving the most genuine intrusion (for definition, see text) without flaring of the teeth. When two central incisors were incorporated in the sectional wire, strong torque forces appeared, especially when the intrusive forces seized more distally. When four or six anterior teeth were pinned in the sectional wire, tooth movement seemed to be under better control. When the six front teeth were incorporated in the sectional wire, the center of resistance (for definition, see text) was located more to the distal side of the canines. It seemed more difficult, however, to define the center of resistance of the four incisors; it was situated approximately distal to the lateral incisors. In some of the intrusive systems, the teeth underwent independent mesial or distal rotations. This was easily observed with the laser measuring techniques used.

  5. Backscattered electron image of osmium-impregnated/macerated tissues as a novel technique for identifying the cis-face of the Golgi apparatus by high-resolution scanning electron microscopy.

    The osmium maceration method with scanning electron microscopy (SEM) enabled to demonstrate directly the three-dimensional (3D) structure of membranous cell organelles. However, the polarity of the Golgi apparatus (that is, the cis-trans axis) can hardly be determined by SEM alone, because there is no appropriate immunocytochemical method for specific labelling of its cis- or trans-faces. In the present study, we used the osmium impregnation method, which forms deposits of reduced osmium exclusively in the cis-Golgi elements, for preparation of specimens for SEM. The newly developed procedure combining osmium impregnation with subsequent osmium maceration specifically visualised the cis-elements of the Golgi apparatus, with osmium deposits that were clearly detected by backscattered electron-mode SEM. Prolonged osmication by osmium impregnation (2% OsO4 solution at 40°C for 40 h) and osmium maceration (0.1% OsO4 solution at 20°C for 24 h) did not significantly impair the 3D ultrastructure of the membranous cell organelles, including the Golgi apparatus. This novel preparation method enabled us to determine the polarity of the Golgi apparatus with enough information about the surrounding 3D ultrastructure by SEM, and will contribute to our understanding of the global organisation of the entire Golgi apparatus in various differentiated cells.

    Full Text Available Within the vast array of ethnographic research methodology, complete-member ethnography (CME is one ethnographic inquiry whose methodological development is still in infantile in intercultural communication research. Specifically in this article, the author includes four major sections to understand and to advance CME. First, the author reviews the historical development of CME, and realizes epistemological intimacy as the core of CME and as how researchers’ complete-memberships may be established. Second, the author explains the concept and practice of epistemological intimacy in extant literature. Third, the author advances the concept of epistemological intimacy to identify and explain five contextual factors that influence a complete-member ethnographer’s complete-membership to his or her research community. The five factors include historicity of identity, institutional memory, situational (intersubjectivity, consensual membership, and symbolic codes. In order to elucidate that said factors are essentially interrelated, the author supplements the five factors with her conceptualizations of selfhood/identity. In the end, the author discusses three potential contributions of how CME can advance critical communication research, which pertain to (a praxis and reflexivity, (b challenging struggles and inequalities in power and privilege, and (c promote hopeful social justice from within.

    Shendong Shangwan coal and its macerals of vitrinite and inertinite were analyzed by 13C-CP/MAS NMR and FTIR and relative structural parameters were also discussed. The results indicate that inertinite has a higher aromaticity and aromatic bridgehead carbons than those of parent coal and vitrinite. The types of naphthalene and anthracene were main aromatic structure in inertinite macrostructure. Vitrinite had more alkylated aromatic, paraffin hydrocarbon, cycloalkanes, aliphatic carbon and higher hydrogen content. The type of benzene was the main aromatic structure; the macrostructure of parent coal has more fH al (quanternary carbon, CH and CH2) and bonded to oxygen(fO al) and naphthalene was its main aromatic structure. The degree of hydroxy association of three sample and C=C stretching vibration are also stronger. The ratio Hal/Har of vitrinite 2. 18 is much higher than that of parent coald. 52) and inertinited. 36), which was consistent with the fact that vitrinite had lower aromaticity; the macrostructure of vitrinite and inertinite have more stretching vibration -CH2 than that of parent coal.%采用13 C-CP/MAS NMR和FTIR测试手段对神东上湾煤及其显微组分富集物进行了分析表征,并对其相关结构特征进行了讨论.结果表明,惰质组富集物较原煤和镜质组富集物有较高的芳香度,桥头芳碳(fsB)也较高,大分子芳香结构以萘和蒽结构为主;镜质组富集物有较多的烷基化取代芳碳和脂肪碳,氢含量相对较多,结构中富含链状烷烃、环状烷烃和芳甲基等,大分子芳香结构以苯结构为主;原煤结构中含有较多的falH(季碳、CH和CH2)和falO(氧接脂碳),原煤芳香结构以萘结构为主.三个煤样结构中羟基缔合程度都比较大,有较强的C=C骨架伸缩振动峰,镜质组富集物的Hal/Har为2.18,远远高于原煤(1.52)和惰质组富集物(1.36),说明镜质组富集物有较多的脂肪结构;与原煤相比,镜质组和惰质组富集物

    1990-10-01

    For each of the 4995 persons listed in the 1989 American Astronomical Society Membership Directory, we noted their total 1984-88 publications as listed in the Author Index of Astronomy and Astrophysics Abstracts. The members are subdivided as retired (mean of 0.61 paper/yr), foreign (3.89), Full (3.34), Division Affiliates (1.76), Associate (1.48), and Junior (0.79) members. For Full members the frequencies of various publication rates are listed; the median is 2.28 papers/yr. The Full members are subdivided by affiliations, namely private institutions (mean of 4.71 papers/yr), university (3.89), government-funded (3.46), commercial company (1.81), and unknown affiliations (0.84). We looked up the listed publications for four high producers who each average 25.7 papers/yr. We found that 55% of those are preprints, abstracts, conference papers, and other secondary material. Furthermore, they average 4.2 authors per original research paper. If we divide each original research paper by the number of authors, these four average only the equivalent of 4.0 single-author research papers/yr. A sample of moderate producers also have 53% of their publications as abstracts, conference papers, etc., and they average 4.2 authors per original research paper. We conclude that the average Full AAS member produces the equivalent of 1/2 single-author original-research paper/yr and 23% of them produce more than 1 such paper/yr.

    The main purpose of the paper is to give predictions of the migration potential from the 7 new EU member countries to the EEA/EU-13 countries. Being able to analyze 'real' migration behavior from these particular countries over the period 1990-2000 helps me to avoid problems related to (double) out......-of sample forecasts and to the assumption of invariance of migration behavior across a space that previous studies had to hold. Results of the econometric analyses reveal the importance of controlling for pairs of countries unobserved heterogeneity. Preliminary results regarding the predictions of future...... gross and net migration flows show that the magnitude of the estimated gross and net migration flows is relatively high and lower, respectively, compared to forecasts from previous studies. Such a development in gross and net migration flows indicates that migration from the new EU member countries...

  6. TEACHING IN ONLINE COURSES: Experiences of Instructional Technology Faculty Members

    2008-04-01

    Full Text Available The Internet and computer technology have altered the education landscape. Online courses are offered throughout the world. Learning about the experiences of faculty members is important to guide practitioners and administrators. Using qualitative research methodology, this study investigated the experiences of faculty members teaching online courses. A convenience sampling was used to select the instructional technology faculty members to investigate their experiences in online courses. Semi-structured interviews with faculty members teaching online courses were used as the primary source to collect data about the experiences of faculty members in online courses. Results of the study showed that faculty members' interest in using technology and the amount of time available to them for online course design affected the quality of online courses. The findings of this study also indicated that design quality of online courses is affected by the interest of faculty members to use the technology and the time that they can devote to planning, designing, and developing online courses. The poor design of existing online courses, high learning expectations of ndividuals from these courses, and the future of online courses are the concerns of faculty members. Higher education institutions should support workshops and trainings to increase the skills and interests of non-instructional design faculty members to design and develop online courses.

  7. Chromosomal aberrations in ISS crew members

    High energy radiation is a major risk factor in manned space missions. Astronauts and cosmonauts are exposed to ionising radiations of cosmic and solar origin, while on the Earth's surface people are well protected by the atmosphere and a deflecting magnetic field. There are now data available describing the dose and the quality of ionising radiation on-board of the International Space Station (ISS). Nonetheless, the effect of increased radiation dose on mutation rates of ISS crew members are hard to predict. Therefore, direct measurements of mutation rates are required in order to better estimate the radiation risk for longer duration missions. The analysis of chromosomal aberrations in peripheral blood lymphocytes is a well established method to measure radiation-induced mutations. We present data of chromosome aberration analyses from lymphocyte metaphase spreads of ISS crew members participating in short term (10-14 days) or long term (around 6 months) missions. From each subject we received two blood samples. The first sample was drawn about 10 days before launch and a second one within 3 days after return from flight. From lymphocyte cultures metaphase plates were prepared on glass slides. Giemsa stained and in situ hybridised metaphases were scored for chromosome changes in pre-flight and post-flight blood samples and the mutation rates were compared. Results obtained in chromosomal studies on long-term flight crew members showed pronounced inter-individual differences in the response to elevated radiation levels. Overall slight but significant elevations of typical radiation induced aberrations, i.e., dicentric chromosomes and reciprocal translocations have been observed. Our data indicate no elevation of mutation rates due to short term stays on-board the ISS.

  13. ASCLS members perceptions regarding research.

    Science.gov (United States)

    Mundt, Lillian; Shanahan, Kristy

    2009-01-01

    One of the benchmarks of a profession is performing, publishing, and presenting research. However, in the Clinical Laboratory Science (CLS) profession, few manuscripts are submitted to the American Society for Clinical Laboratory Science (ASCLS) journal, Clinical Laboratory Science, on a regular basis. The problem is that perceptions regarding research, and the role of laboratory professional as researchers, held by ASCLS members may be contributing to the low number of manuscript submissions. To assess these perceptions, an anonymous Likert-scale survey was developed and delivered online using Survey Monkey. Members of ASCLS, with email addresses, were chosen to participate in this survey because they may be most likely to contribute manuscripts for a journal by their own society. About 10% of the 7,000 members who were invited by email chose to participate in this study. Most participants agreed that 1) there is important information to be gathered from research on clinical laboratory specimen results (99.6%), 2) research contributes valuable information to the body of CLS knowledge (99.2%), and 3) conducting research is one of the benchmarks of a profession (92.4%). The majority of participants felt that there are inadequate resources (68.8%) and not enough time (83%) available to conduct research in the clinical laboratory setting. Most participants recognize that many laboratory activities constitute research (86.2%), but only a few are willing to publish research findings on their own (29.2%). Those who are the most likely to publish research findings include men, university faculty, and members who are over 60 years old. University faculty are the most likely to assist others in the writing process. These results show an opportunity exists for ASCLS to foster collaborations between bench technologists and educators willing to assist with the publication process.

  14. Perspectives and expectations of union member and non- union member teachers on teacher unions

    2015-12-01

    Full Text Available Unions, which can be regarded as one of the constitutive elements of democracy, are the pressure groups in political and social fields. Unions were born out of industrial confrontations and expanded into the field of public services over time, and thus teachers – who are also public employees-, also obtained the right to establish and affiliate to unions. In this research the views of union member and non-union member teachers on the most important functions and operational effectiveness of unions, teachers’ expectations from unions and teachers’ evaluation of the solidarity, competition and cooperation between unions were determined and the perspectives of teachers on unionization were revealed. qualitative research design was used. The data needed were collected through semi-structured interviews from volunteering union member and non-union member teachers who were working in the primary and secondary schools in Ankara province and who were selected through “maximum variation sampling approach”. The data were then analyzed by using the content analysis technique. In conclusion, it was found that political ideology was the most important reason for membership of teachers’ unions. Protection and development of personal rights was found to be the most important function of teacher unions and unions were thought to be insufficient in performing those functions.

    Full Text Available Isolation of Leishmania parasite and species identification are important for confirmation and to help define the epidemiology of the leishmaniasis. Mice are often used to isolate pathogens, but the most common mouse strains are resistant to infection with parasites from the Leishmania (Viannia subgenus. In this study we tested the inoculation of interferon gamma knockout (IFNγ KO mice with biopsy macerates from Leishmania-infected patients to increase the possibility of isolating parasites. Biopsies from twenty five patients with clinical signs of leishmaniasis were taken and tested for the presence of parasites. Immunohistochemical assay (IHC and conventional histopathology detected the parasite in 88% and 83% of the patients, respectively. Leishmania sp. were isolated in biopsy macerates from 52% of the patients by culture in Grace's insect medium, but 13% of isolates were lost due to contamination. Inoculation of macerates in IFNγ KO mice provides isolation of parasites in 31.8% of the biopsies. Most isolates belong to L. (Viannia subgenus, as confirmed by PCR, except one that belongs to L. (Leishmania subgenus. Our preliminary results support the use of IFNγ KO mice to improve the possibility to isolate New World Leishmania species.O isolamento e a identificação da espécie de parasito do gênero Leishmania são importantes para a confirmação e auxiliam na epidemiologia da leishmaniose.

    2012-04-01

    Data from a sample of 83 elected community leaders and 391 direct-report staff (resulting in 333 useable leader-member dyads) were reanalyzed to test relations between self-other rating agreement of servant leadership and member-reported leader-member exchange (LMX). Polynomial regression analysis indicated that the self-other rating agreement model was not statistically significant. Instead, all of the variance in member-reported LMX was accounted for by the others' ratings component alone.

  1. How do they become nodes? Revisiting team member network centrality.

    Liu, Yuwen; Ipe, Minu

    2010-01-01

    The present study examines the antecedents of team member network centrality using a sample of 207 team members. Team member network centrality indicates how closely the individual is linked to others in the group. The authors investigated the role of personality traits, interpersonal citizenship behavior (ICB), education, and team tenure on an individual's network centrality. The authors also examined the mediating effect of ICB on the relationship between personality traits and team member network centrality. Results supported the relation between (a) personal traits--conscientiousness and agreeableness--and (b) ICB and network centrality. In addition, ICB mediated the relation between conscientiousness and network centrality and between agreeableness and network centrality, respectively. That is, people who are more conscientious and agreeable manifest more ICB and therefore more possibly become nodes within their teams' social network. Further, results supported the idea that education and team tenure are positively related to network centrality. The authors discuss the theoretical contributions and implications.

    Purpose/Objectives To describe the impact of the cancer experience on the health behaviors of survivors’ family members and to determine factors associated with family members’ intentions for health behavior change. Design Descriptive, cross-sectional, correlational study. Setting A National Cancer Institute-designated comprehensive cancer center in the Midwestern United States. Sample 39 family members and 50 patients with diagnoses of breast, colon, head and neck, lung, or prostate cancer who were completing definitive cancer treatment. Methods Patients and family members were approached in the clinic at 3 weeks or less before the completion of their course of treatment. Family members completed surveys and a structured interview in-person or via telephone. Main Research Variables Intention, perceived benefit, and confidence for eating a healthy diet, physical activity, and smoking cessation; emotional distress; and family cohesiveness, conflict, and expressiveness. Findings Family members had, on average, high ratings for intention, perceived benefit, and confidence related to behaviors of eating a healthy diet and doing 30 minutes of daily moderate physical activity. They also had high ratings for the extent to which the cancer experience raised their awareness of their own cancer risk and made them think about having screening tests; ratings were lower for making changes in their health behaviors. Distress scores of family members were high at the completion of cancer treatment. Greater intention for physical activity and nutrition was associated with greater perceived benefit and confidence. Higher scores for family expressiveness was associated with intention for nutrition. Greater intention for smoking cessation was associated only with confidence. Conclusions Family members expressed strong intentions to engage in health-promoting behaviors related to physical activity and nutrition at the transition to post-treatment survivorship.

    1998-08-01

    This project provides coal samples and accompanying analytical data for research by DOE contractors and others. All 56 samples have been purged with argon before storage, and the 33 samples in the DECS series are heat-sealed in foil laminate bags and stored under refrigeration. Eleven DECS samples have been collected under the current contract. Basic characterization, standardized liquefaction analyses and organic geochemical analyses have been completed. Distribution of samples and data is continuing, with processing of samples being performed as needed. Nineteen samples, 90 data printouts, and individual data items from 416 samples were distributed during the quarter. Trends and relationships observed in liquefaction and organic geochemical analyses performed under the contract are summarized in this report. Liquefaction results using tetralin were similar to those using 1-methylnaphthalene under the same run conditions. Properties of individual coals, such as maceral composition and corresponding organic chemical components, were important in explaining liquefaction behavior. NMR and py/gc/ms results illustrated trends based on coal rank, and revealed outliers which might be of special interest, for example low-phenolic coals which limit retrogressive reactions and permit greater liquefaction conversion.

    A soil sampling device and a sample containment device for containing a soil sample is disclosed. In addition, a method for taking a soil sample using the soil sampling device and soil sample containment device to minimize the loss of any volatile organic compounds contained in the soil sample prior to analysis is disclosed. The soil sampling device comprises two close fitting, longitudinal tubular members of suitable length, the inner tube having the outward end closed. With the inner closed tube withdrawn a selected distance, the outer tube can be inserted into the ground or other similar soft material to withdraw a sample of material for examination. The inner closed end tube controls the volume of the sample taken and also serves to eject the sample. The soil sample containment device has a sealing member which is adapted to attach to an analytical apparatus which analyzes the volatile organic compounds contained in the sample. The soil sampling device in combination with the soil sample containment device allow an operator to obtain a soil sample containing volatile organic compounds and minimizing the loss of the volatile organic compounds prior to analysis of the soil sample for the volatile organic compounds.

    Science.gov (United States)

    Stallings, J. M.

    1993-02-01

    Discontinuities such as internal hinges are commonly encountered in framed structures. A general method of including discontinuities in stiffness method analyses of planar frames by the release of member end forces is developed. Modifications are made to the member stiffness matrix and equivalent joint load vector to account for the released end forces. A FORTRAN algorithm is given that makes the necessary modifications to the member stiffness matrix and equivalent joint load vector for the standard planar frame member. The algorithm allows combinations of up to three member end forces to be released (specified at zero or nonzero values). An algorithm is also given that calculates the unknown member end displacements at the released member end forces. Numerical examples are given to illustrate the uses and capabilities of the algorithms.

  2. The effect of commercial enzyme preparation-assisted maceration on the yield, quality, and bioactivity of essential oil from waste carrot seeds (Daucus carota L.

    Full Text Available Eight enzyme preparations were screened with a view to maximizing the yield of carrot seed essential oil. Three of the eight enzyme preparations investigated, lipase from Mucor circinelloides, XPect® pectinase, and Esperase® protease, significantly influenced the amount of essential oil obtained, with Esperase® being the most effective. The Taguchi method was applied to optimize the processing conditions for the Esperase® protease. Under the optimum conditions, the essential oil yield increased by approximately 48%. The main constituent compounds in the oil are: carotol (OeA: 40.80%–OeB: 46.17%, daucol (OeA: 7.35%–OeB: 6.22%, sabinene (OeA: 5.12%–OeB: 6.13%, alpha-pinene (OeA: 4.24%–OeB: 5.11% and geranyl acetate (OeA: 4.50%–OeB: 3.68%. As compared to the control sample, the essential oil obtained from enzyme-pretreated carrot seeds has the same biological activity against Bacillus subtilis and Candida sp., lower activity against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa, and higher activity against Aspergillus niger and Penicillium expansum.Ocho preparados enzimáticos fueron seleccionados con el fin de maximizar el rendimiento de aceites esenciales de semillas de zanahoria.

    This article considers various kinds of probability and non-probability samples in both experimental and survey studies. Throughout, how a sample is chosen is stressed. Size alone is not the determining consideration in sample selection. Good samples do not occur by accident; they are the result of a careful design. (Author/JAZ)

  7. Slice Sampling

    Neal, R M

    2000-01-01

    Markov chain sampling methods that automatically adapt to characteristics of the distribution being sampled can be constructed by exploiting the principle that one can sample from a distribution by sampling uniformly from the region under the plot of its density function. A Markov chain that converges to this uniform distribution can be constructed by alternating uniform sampling in the vertical direction with uniform sampling from the horizontal `slice' defined by the current vertical position, or more generally, with some update that leaves the uniform distribution over this slice invariant. Variations on such `slice sampling' methods are easily implemented for univariate distributions, and can be used to sample from a multivariate distribution by updating each variable in turn. This approach is often easier to implement than Gibbs sampling, and more efficient than simple Metropolis updates, due to the ability of slice sampling to adaptively choose the magnitude of changes made. It is therefore attractive f...

    Whalen, Mathilde Logan; Loper, Ann Booker

    2014-03-01

    This study examines the association between the incarceration of a household member and adolescent pregnancy, and evaluates whether this association extends beyond that of other variables associated with sexual health. We used data from 12 waves of the National Longitudinal Survey of Youth: Child and Young Adult. After eliminating males and individuals who did not respond to key questions, a sample of 1,229 girls (ages 14-19) was analyzed. Girls who experienced the incarceration of a household member faced more demographic and family environment risk factors than those who did not. Regression analyses demonstrated that the addition of a household incarceration variable afforded superior prediction of teenage pregnancy relative to the prediction based on demographic and family features alone. Programs that are directed toward reducing teen pregnancy will benefit from attention to the home situation of the at-risk girl, particularly the experience of household member incarceration and related family dynamics.

    2009-04-01

    The paper examines how family members in 18 countries attempt to influence each other to drink less. Data come from the GENACIS (Gender, Alcohol and Culture: an International Study) dataset. Countries included were Argentina, Costa Rica, Czech Republic, Denmark, Finland, Germany, Hungary, Iceland, India, Japan, Nigeria, Norway, Spain, Sri Lanka, Sweden, Uganda, UK and Uruguay (overall sample 44,115). In each country, the percentage of people who had experienced family member pressure to drink less were compared to country abstinence rate, mean drinking volume per drinker and other societal-level factors. While countries differed greatly on proportion of drinkers having experienced family members' pressure to drink less, in all countries drinking women reported less pressure than drinking men in their own society. In all studied countries, informal pressure was exerted most often by the spouse or sexual partner. However, other family members were also involved. Informal pressure was found to be highly correlated with the country's socioeconomic conditions. Informal pressure to drink less by family members is on one hand an expression of social and family problems, caused by heavy drinking, especially in the economically less developed countries, suggesting alcohol-related deprivation. On the other hand, similar gender differences were seen in all the societies, men reporting receiving more informal pressure than women. Thus, informal pressure to drink less tended to reflect the gender conflict caused by heavy use of alcohol by men.

    This report characterizes the mineralogy of the Culebra Member of the Rustler Formation based on studies of samples from cores of eight boreholes surrounding the WIPP repository. This investigation has three main goals: to obtain accurate modal compositions of all the samples selected; to investigate both the lateral and vertical variation of the mineralogy of the Culebra unit; and, to characterize water-bearing fracture surfaces in particular detail. The Culebra Dolomite member of the Rustler Formation is mineralogically and texturally heterogeneous, both vertically and horizontally. Although the predominant mineral is dolomite, important constituents of the formation are clay, quartz, gypsum, and calcite. Trace minerals include halite, phyllosilicates of metamorphic origin, feldspar, and pyrite. 24 refs., 90 figs., 27 tabs.

    The American Thoracic Society (ATS), in collaboration with George Mason University, surveyed a random sample of ATS members to assess their perceptions of, clinical experiences with, and preferred policy responses to climate change. An e-mail containing an invitation from the ATS President and a link to an online survey was sent to 5,500 randomly selected U.S. members; up to four reminder e-mails were sent to nonrespondents. Responses were received from members in 49 states and the District of Columbia (n = 915); the response rate was 17%. Geographic distribution of respondents mirrored that of the sample. Survey estimates' confidence intervals were ±3.5% or smaller. Results indicate that a large majority of ATS members have concluded that climate change is happening (89%), that it is driven by human activity (68%), and that it is relevant to patient care ("a great deal"/"a moderate amount") (65%). A majority of respondents indicated they were already observing health impacts of climate change among their patients, most commonly as increases in chronic disease severity from air pollution (77%), allergic symptoms from exposure to plants or mold (58%), and severe weather injuries (57%). A larger majority anticipated seeing these climate-related health impacts in the next 2 decades. Respondents indicated that physicians and physician organizations should play an active role in educating patients, the public, and policy makers on the human health effects of climate change. Overall, ATS members are observing that human health is already adversely affected by climate change and support responses to address this situation.

    2014-06-01

    Convenience sampling and purposive sampling are two different sampling methods. This article first explains sampling terms such as target population, accessible population, simple random sampling, intended sample, actual sample, and statistical power analysis. These terms are then used to explain the difference between "convenience sampling" and purposive sampling." Convenience sampling is a non-probabilistic sampling technique applicable to qualitative or quantitative studies, although it is most frequently used in quantitative studies. In convenience samples, subjects more readily accessible to the researcher are more likely to be included. Thus, in quantitative studies, opportunity to participate is not equal for all qualified individuals in the target population and study results are not necessarily generalizable to this population. As in all quantitative studies, increasing the sample size increases the statistical power of the convenience sample. In contrast, purposive sampling is typically used in qualitative studies. Researchers who use this technique carefully select subjects based on study purpose with the expectation that each participant will provide unique and rich information of value to the study. As a result, members of the accessible population are not interchangeable and sample size is determined by data saturation not by statistical power analysis.

    We have used the Spitzer Space Telescope to obtain Multiband Imaging Photometer for Spitzer (MIPS) 24 um photometry for 37 members of the ~100 Myr old open cluster Blanco 1. For the brightest 25 of these stars (where we have 3sigma uncertainties less than 15%), we find significant mid-IR excesses for eight stars, corresponding to a debris disk detection frequency of about 32%. The stars with excesses include two A stars, four F dwarfs and two G dwarfs. The most significant linkage between 24 um excess and any other stellar property for our Blanco 1 sample of stars is with binarity. Blanco 1 members that are photometric binaries show few or no detected 24 um excesses whereas a quarter of the apparently single Blanco 1 members do have excesses. We have examined the MIPS data for two other clusters of similar age to Blanco 1 -- NGC 2547 and the Pleiades. The AFGK photometric binary star members of both of these clusters also show a much lower frequency of 24 um excesses compared to stars that lie near the single...

    This paper describes the results of a study to evaluate, in probabilistic terms, the effects of age-related degradation on the structural performance of reinforced concrete members at nuclear power plants. The paper focuses on degradation of reinforced concrete flexural members and shear walls due to the loss of steel reinforcing area and loss of concrete area (cracking/spalling). Loss of steel area is typically caused by corrosion while cracking and spalling can be caused by corrosion of reinforcing steel, freeze-thaw, or aggressive chemical attack. Structural performance in the presence of uncertainties is depicted by a fragility (or conditional probability of failure). The effects of degradation on the fragility of reinforced concrete members are calculated to assess the potential significance of various levels of degradation. The fragility modeling procedures applied to degraded concrete members can be used to assess the effects of degradation on plant risk and can lead to the development of probability-based degradation acceptance limits.

    The present study assessed the impact of suicide and distress on suicidal ideation in a sample of 93 Portuguese family members bereaved by suicide. A control community sample of 102 adults also participated. After controlling for educational level, those bereaved by the suicide of a family member were found to have higher levels of suicidal ideation. Forty-two percent of family members had Suicide Ideation Questionnaire scores at or above the cutoff point. General distress, depression, anxiety, and hostility related to suicidal ideation, whereas time since suicide also interacted with general distress and depression in predicting suicidal ideation.

    (238)U, (232)Th, (222)Rn and (220)Rn concentrations were measured inside various Moroccan black soap samples widely used by the Moroccan population in traditional baths (Hammans) by using both CR-39 and LR-115 type II solid state nuclear track detectors. The measured (238)U, (232)Th, (222)Rn and (220)Rn concentrations, respectively, ranged from (3.7 ± 0.2) to (11.7 ± 0.7) mBq kg(-1), (0.11 ± 0.01) to (0.32 ± 0.02) mBq kg(-1), (3.8 ± 0.2) to (11.6 ± 0.6) Bq kg(-1) and (0.10 ± 0.01) to (0.31 ± 0.02) Bq kg(-1) for the Moroccan black soap samples studied. The influence of pollution on the concentrations of these radionuclides inside the considered Moroccan black soap was investigated. A new dosimetric model for evaluating annual committed effective doses due to (238)U, (232)Th and (222)Rn to the skin of different age groups of the Moroccan populations from the application of the black soap samples studied was developed. The maximum total committed effective dose to the skin due to (238)U, (232)Th and (222)Rn from the application of unpolluted black soap samples 20 min per week by the Moroccan populations was found to be equal to (0.88 ± 0.05) μ Sv y(-1) cm(-2).

    Full Text Available The article concerns modern state and development of migration processes in SCO member states. As a main method of research statistical analysis was applied. The article shows that migration streams between SCO member states are rather intensive, and the problem of labor migration becomes more and more urgent. The countries of consuming and supplying of labour force are clearly differentiated in the region. For some countries, labor export is the key sector of economy. At the same time, interstate relations between SCO member states sometimes are rather disputed. The most urgent factors causing the development of migration processes in the region were determined. Among them, thefactor of growing outflows from China isespecially noted. It is noted that migration processes are discussed by SCO member states nowadays in terms of illegal migration and international criminality connected with it. It means that the question of labor migration is a real problem. It is indicated that the creation of a specific joint commission on migration policy affiliated with the Council of Foreign Ministers of SCO member states is the necessary condition of effective interaction in migration questions within the framework of Shanghai Cooperation Organization.

    Defining optimal nutrient requirements is imperative to ensure crew health on long-duration space exploration missions. To date, nutrient requirement data have been extremely limited because of small sample sizes and difficulties associated with collecting biological samples. In this study, we examined changes in body composition, bone metabolism, hematology, general blood chemistry, and blood levels of selected vitamins and minerals after long-duration (128-195 d) space flight aboard the International Space Station. Crew members consumed an average of 80% of the recommended energy intakes, and on landing day their body weight had decreased (P=0.051). After flight, hematocrit was less, and serum femtin was greater than before flight (PSerum iron, ferritin saturation, and transferrin had decreased after flight. The finding that other acute-phase proteins, including ceruloplasmin, retinol binding protein, transthyretin, and albumin were not changed after flight suggests that the changes in iron metabolism may not be strictly due to an inflammatory response. Urinary 8- hydroxy-2'-deoxyguanosine concentration was greater and superoxide dismutase was less after flight, indicating that oxidative damage had increased (Pserum 25-hydroxyvitamin D was significantly decreased after flight (Pserum concentration of bone-specific alkaline phosphatase, was elevated only in crew members who landed in Russia, probably because of the longer time lapse between landing and sample collection. These data provide evidence that bone loss, compromised vitamin D status, and oxidative damage remain critical concerns for long-duration space flight.

  6. Radioactive waste management in member states

    The objective of this part of the report is to present a brief overview of key issues in radioactive waste management on a nation-by-nation basis. Member State representatives were asked to address nine questions in no more than three or four pages. Hence, by design, the presentations are not comprehensive. Even so, the information set out here should provide the reader valuable insights into the nature of problems associated with radioactive waste management. The materials may also be used as a ready reference for specific information about radioactive waste management in individual Member States as well as for comparative purposes. (author).

    The function of p53 is best understood in response to genotoxic stress, but increasing evidence suggests that p53 also plays a key role in the regulation of metabolic homeostasis. p53 and its family members directly influence various metabolic pathways, enabling cells to respond to metabolic stress. These functions are likely to be important for restraining the development of cancer but could also have a profound effect on the development of metabolic diseases, including diabetes. A better understanding of the metabolic functions of p53 family members may aid in the identification of therapeutic targets and reveal novel uses for p53-modulating drugs.

  10. Development prospects of the banking industry in the new EU member countries and forthcoming member countries

    Directory of Open Access Journals (Sweden)

    2006-05-01

    Full Text Available Bank consolidation has substantially decreased the number of banks in European banking, which has had important implications for the banking sectors structure in all EU member countries. The consolidation processes have had a tremendous impact on the developments in banking sectors of new EU member countries, wheremajor structural changes have been initiated mostly by new entrant banks from the old EU member countries. The future banking development in new EU member countries will very likely follow some main patterns known from the old EU members. Rather speculative conjectures, which are based on a comparison with banking sectors in other EU member countries indicate, that the total-asset-to-GDPratio in new member countries should further improve in the future. The banking sector growth will be based mostly on the growth of the credit to non-banking sector, while banks are not expected anymore to use non-bank deposits as a predominant way of funding. Instead potentials for alternative funding possibilities should be activated. Although the non-bank financial intermediaries in new EU membersrepresent a serious competition to banks, their relative underdevelopment prevents them from impacting the developments in banking sectors as known from old EU member countries.

  15. Inelastic Deformation Analysis of Aluminum Bending Members

    Institute of Scientific and Technical Information of China (English)

    CHENG Ming; SHI Yongjiu; WANG Yuanqing

    2006-01-01

    Aluminum alloys are typical nonlinear materials, and consequently bending members made of this material exhibit a nonlinear behavior. Most design codes do not pay much attention to such deformations and adopt a simple linear analysis for the calculation of deflections. This paper presents an investigation of the nonlinear deformation of aluminum bending members using the finite-element analysis (FEA). The plastic adaptation coefficient, which can be used to limit the residual deflection, is introduced, and the influence of residual deflection is investigated. A method for evaluating the plastic adoption coefficient is proposed. This paper also shows the load-deflection curve of aluminum bending members and the influence of several parameters. A semi-empirical formula is derived, and some numerical examples are given by FEA. The coefficients of the semi-empirical formula are modified by the FEA results using the nonlinear fitting method. Based on these results, two improved design methods for strength and deformation of aluminum bending members are proposed. Through the comparison with test data, these methods are proved to be suitable for structural design.

    We report on the properties of pre-main-sequence objects in the Taurus molecular clouds as observed in 7 mid- and far-infrared bands with the Spitzer Space Telescope. There are 215 previously-identified members of the Taurus star-forming region in our ~44 square degree map; these members exhibit a range of Spitzer colors that we take to define young stars still surrounded by circumstellar dust (noting that ~20% of the bonafide Taurus members exhibit no detectable dust excesses). We looked for new objects in the survey field with similar Spitzer properties, aided by extensive optical, X-ray, and ultraviolet imaging, and found 148 candidate new members of Taurus. We have obtained follow-up spectroscopy for about half the candidate sample, thus far confirming 34 new members, 3 probable new members, and 10 possible new members, an increase of 15-20% in Taurus members.

    Cardiopulmonary arrest (CPA) teams, known as code teams, provide coordinated and evidenced-based interventions by various disciplines during a CPA. Teamwork behaviors are essential during CPA resuscitation and may have an impact on patient outcomes. The purpose of this study was to explore the perceptions of teamwork during CPA events among code team members and to determine if differences in perception existed between disciplines within the code team. A prospective, descriptive, comparative design using the Code Teamwork Perception Tool online survey was used to assess the perception of teamwork during CPA events by medical residents, critical care nurses, and respiratory therapists. Sixty-six code team members completed the Code Teamwork Perception Tool. Mean teamwork scores were 2.63 on a 5-point scale (0-4). No significant differences were found in mean scores among disciplines. Significant differences among scores were found on 7 items related to code leadership, roles and responsibilities between disciplines, and in those who had participated on a code team for less than 2 years and certified in Advanced Cardiac Life Support for less than 4 years. Teamwork perception among members of the code team was average. Teamwork training for resuscitation with all disciplines on the code team may promote more effective teamwork during actual CPA events. Clinical nurse specialists can aid in resuscitation efforts by actively participating on committees, identifying opportunities for improvement, being content experts, leading the development of team training programs, and conducting research in areas lacking evidence.

    Full Text Available It is important that married couples seek legal advice with regard to the assets falling within their joint estate, more particularly their retirement benefits. This article reflects on the entitlement (if any of non-member spouses to their spouses' retirement fund benefits. Pension benefits can be due before, during or after divorce, and parties to the marriage should be aware of their rights with regard to the accruing pension benefits of their spouses. While it is settled law that non-member spouses are entitled to receive a portion of their member spouses' pension benefits (known as "pension interest" immediately on divorce, it is not particularly clear whether non-member spouses are also entitled to receive the same before or sometime after divorce. In this article I provide a contextual understanding of the entitlements (if any which spouses or former spouses of members of pension funds have on such member spouses' retirement benefits. Furthermore, it shown in this article that various divisions of South African High Courts have been inconsistent in how they have approached the issue of the pension interest between divorcing spouses or divorced ex-spouses.

    Recognizing other individuals by integrating different sensory modalities is a crucial ability of social animals, including humans. Although cross-modal individual recognition has been demonstrated in mammals, the extent of its use by birds remains unknown. Herein, we report the first evidence of cross-modal recognition of group members by a highly social bird, the large-billed crow (Corvus macrorhynchos). A cross-modal expectancy violation paradigm was used to test whether crows were sensitive to identity congruence between visual presentation of a group member and the subsequent playback of a contact call. Crows looked more rapidly and for a longer duration when the visual and auditory stimuli were incongruent than when congruent. Moreover, these responses were not observed with non-group member stimuli. These results indicate that crows spontaneously associate visual and auditory information of group members but not of non-group members, which is a demonstration of cross-modal audiovisual recognition of group members in birds.

  1. Members' attendance rates and outcomes of relationship education groups: A consensus-dispersion analysis.

    Kivlighan, D Martin; Owen, Jesse; Antle, Becky

    2017-04-01

    Relationship education programs (REPs) are an effective way to enhance relationship communication, prevent relational distress, and increase relationship quality. Most REPs are delivered in a group format; however, there is little known about the influence of group processes on outcomes for these programs, such as group members' attendance. Therefore, the current study applied a dispersion-consensus model to test the impact of attendance at the member and group levels on group members' REP outcomes. In a sample of 558 lower income, primarily African American participants, we examined whether individual and group attendance rates influenced posttreatment communication patterns and relationship quality. Results indicated that an individual group member's attendance was significantly and positively related to their posttreatment relationship quality, although this relationship is complex. Specifically, this relationship was stronger in groups with higher levels of attendance as well as groups with more attendance variability. In addition, results indicated that group members reported better posttreatment relationship quality in groups with less variability in members' attendance. However, we found a significant interaction between attendance consensus and variability, and an individual group member's posttreatment relationship quality, suggesting that group members report higher levels of relationship quality in groups where the attendance of the group as a whole is lower yet more consistent. No significant relationships were found for group member's posttreatment communication patterns. Our findings suggest that the rate and variability in the group's attendance, as well as an individual group member's own attendance significantly impacts their posttreatment relationship quality in complex ways.

    Defining optimal nutrient requirements is imperative to ensure crew health on long-duration space exploration missions. To date, nutrient requirement data have been extremely limited because of small sample sizes and difficulties associated with collecting biological samples. In this study, we examined changes in body composition, bone metabolism, hematology, general blood chemistry, and blood levels of selected vitamins and minerals after long-duration (128-195 d) space flight aboard the International Space Station. Crew members consumed an average of 80% of the recommended energy intakes, and on landing day their body weight had decreased (P=0.051). After flight, hematocrit was less, and serum femtin was greater than before flight (Pretinol binding protein, transthyretin, and albumin were not changed after flight suggests that the changes in iron metabolism may not be strictly due to an inflammatory response. Urinary 8- hydroxy-2'-deoxyguanosine concentration was greater and superoxide dismutase was less after flight, indicating that oxidative damage had increased (P<0.05). Despite the reported use of vitamin D supplements during flight, serum 25-hydroxyvitamin D was significantly decreased after flight (P<0.01). Bone resorption was increased after flight, as indicated by several urinary markers of bone resorption. Bone formation, assessed by serum concentration of bone-specific alkaline phosphatase, was elevated only in crew members who landed in Russia, probably because of the longer time lapse between landing and sample collection. These data provide evidence that bone loss, compromised vitamin D status, and oxidative damage remain critical concerns for long-duration space flight.

Seven samples (four from calcareous silts near the member's base exposed by building work at the Los Atajos Community Centre, and three from the underlying calcareous claystones of the Brasso Formation) were examined for calcareous microfossils. These indicate a conformable succession encompassing an overall regression. The oldest of the claystone samples, of uppermost early Middle Miocene Globorotalia fohsi fohsi Zone age (N11), contained an upper bathyal benthic foraminiferal assemblage, while the younger claystone samples yielded abundant, shallow neritic Hanzawaia carstensi. The recovery of the planktonic foraminifera Globorotalia mayeri but absence of Globigerinoides subquadratus suggest a Middle Miocene age (Globorotalia mayeri planktonic foraminiferal Zone; N14) for both the uppermost Brasso claystone sample and the Los Atajos Member. The benthic foraminiferal fauna in the Los Atajos is dominated by Rosalina subaraucana, with subdominant Cibicides ex gr. aknerianus and C. floridanus sensu Galloway and Heminway, and common Elphidium spp. This faunal succession has a close affinity with that of parts of the Lower to Middle Miocene Brasso Formation, especially the N10 Guaracara Limestone Member and the clays on which it sits. However, the Los Atajos Member assemblage differs markedly from that of the overlying Late Miocene San José Calcareous Silt Member of the Manzanilla Formation, from which the Los Atajos is separated by an unconformity of Globorotalia menardii (N15) Zone age. On these grounds, the Los Atajos Member is here placed within the Brasso Formation. The low diversity, high dominance benthic foraminiferal fauna and the associated ostracod assemblage in the Los Atajos are indicative of inner to shallower middle neritic palaeodepths in a carbonate-prone palaeoenvironment with marine vegetation and strong current action

    To evaluate the effects of 2- and 3-tiered pharmacy benefit plans on member attitudes regarding their pharmacy benefits. We performed a mail survey and cross-sectional comparison of the outcome variables in a large managed care population in the western United States. Participants were persons with chronic disease states who were in 2- or 3-tier copay drug plans. A random sample of 10,662 was selected from a total of 25,008 members who had received 2 or more prescriptions for a drug commonly used to treat one of 5 conditions: hypertension, diabetes, dyslipidemia, gastroesophageal reflux disease (GERD), or arthritis. Statistical analysis included bivariate comparisons and regression analysis of the factors affecting member attitudes, including satisfaction, loyalty, health plan choices, and willingness to pay a higher out-of-pocket cost for medications. A response rate of 35.8% was obtained from continuously enrolled plan members. Respondents were older, sicker, and consumed more prescriptions than nonrespondents. There were significant differences in age and health plan characteristics between 2- and 3-tier plan members: respondents aged 65 or older represented 11.7% of 2-tier plan members and 54.7% of 3-tier plan members, and 10.0% of 2-tier plan members were in Medicare+Choice plans versus 61.4% in Medicare+Choice plans for 3-tier plan members (Pbrand-name medications, in general, they were not willing to pay more than 10 dollars (in addition to their copayment amount) for these medications. Older respondents and sicker individuals (those with higher scores on the Chronic Disease Indicator) appeared to have more positive attitudes toward their pharmacy benefit plans in general. Higher reported incomes by respondents were also associated with greater satisfaction with prescription drug coverage and increased loyalty toward the pharmacy benefit plan. Conversely, the more individuals spent for either their health care or prescription medications, the less satisfied

  5. Method of recertifying a loaded bearing member

    A method is described of recertifying a loaded bearing member using ultrasound testing to compensate for different equipment configurations and temperature conditions. The standard frequency F1 of a reference block is determined via an ultrasonic tone burst generated by a first pulsed phased locked loop (P2L2) equipment configuration. Once a lock point number S is determined for F1, the reference frequency F1a of the reference block is determined at this lock point number via a second P2L2 equipment configuration to permit an equipment offset compensation factor Fo1=((F1-F1a)/F1)(1000000) to be determined. Next, a reference frequency F2 of the unloaded bearing member is determined using a second P2L2 equipment configuration and is then compensated for equipment offset errors via the relationship F2+F2(Fo1)/1000000. A lock point number b is also determined for F2. A resonant frequency F3 is determined for the reference block using a third P2L2 equipment configuration to determine a second offset compensation factor F02=((F1-F3)/F1) 1000000. Next the resonant frequency F4 of the loaded bearing member is measured at lock point number b via the third P2L2 equipment configuration and the bolt load determined by the relationship (-1000000)CI(((F2-F4)/F2)-Fo2), wherein CI is a factor correlating measured frequency shift to the applied load. Temperature compensation is also performed at each point in the process.

Collective members can be defined as organizations having both full self-government rights and entitlements to decision-making processes in the political parties in which they are embedded. This article proposes a basic descriptive typology of collective members that takes into consideration their sociopolitical nature (party political or functional and their pattern of articulation within the party in which they are embedded (whether they help to articulate the whole party structure or not. It also illustrates these subtypes by examining European organizations that meet (or are close to meeting the main defining characteristics of collective members. This examination is based on the analysis of all parties that attained at least 4% of the votes in the last national parliamentary elections in 10 European countries. The article concludes with an analysis of the determinants and prospects of this type of party structure.Este artículo estudia los miembros colectivos de los partidos políticos.

  12. How well does end-member modelling analysis of grain size data work?

    Science.gov (United States)

    Schulte, Philipp; Dietze, Michael; Dietze, Elisabeth

    2014-05-01

    End-member modelling analysis (EMMA) is a powerful and flexible statistic approach to identify and quantify generic sediment transport processes from multimodal grain-size distributions. EMMA has been introduced over 15 years ago and is now available in different approaches as encapsulated FORTRAN code (Weltje, 1997), Matlab-script (Dietze et al., 2012) and the R-package EMMAgeo (Dietze and Dietze, 2013). EMMA was mainly used to reconstruct past sedimentation processes in a variety of sedimentary environments (marine, aeolian, lacustrine). Typically, it is rather difficult to assess how meaningful and well the model performs in a certain environment, since neither the actual process end-members (generic grain-size distributions sorted by a certain sediment transport) nor their individual contributions to each sample are known a priori. To allow a comprehensive performance test, we sampled a set of four known process end-members: alluvial sand (main mode: 0.70±0.55 φ), dune sand (main mode: 1.35±0.60 φ), loess (main mode: 4.71±0.65 φ) and overbank deposit (main mode: 5.81±1.62 φ). High resolution grain-size information is based on laser-diffraction analysis (116 classes). The four process end-members were artificially mixed with random, but known proportions to yield 100 samples. This mixed data set was measured again with the laser particle size analyser and served as input for EMMA within the R-package EMMAgeo. This contribution discusses the ability of EMMA to identify and characterise the four distinct process end-members and quantify their contributions to each sample. Different ways to estimate uncertainties are presented. Further evaluations focus on the influence of numbers of included samples, numbers of grain-size classes, vertical mixing of samples (simulating turbation) and self-similarity of process end-members.

  13. Family member involvement in audiology appointments with older people with hearing impairment.

    2015-02-01

    This study aimed to investigate family members' involvement in audiology rehabilitation appointments. Audiology appointments were video-recorded and analysed using quantitative coding and conversation analysis (CA). The study sample included 13 audiologists, 17 older adults with hearing impairment, and 17 family members. Initial coding showed that family members participated in 12% of the total talk time during audiology appointments. The CA results demonstrated that family members were not typically invited to join the conversation. However, family members would self-select to speak by: (1) responding to questions from the audiologist which were directed at the client; (2) self-initiating expansions on clients' turns; and (3) self-initiating questions. When family members did participate in the interaction, audiologists typically responded by shifting the conversation back to the client. While family members currently have minimal participation in audiology appointments, they display a strong interest in being involved and sharing their experiences of the client's hearing impairment. The findings suggest support for implementing family-centred care principles in audiology practice.

    Member 1 of the Swartkrans Formation is comprised of two sedimentary infills, the Lower Bank (LB) and the Hanging Remnant (HR). Together, the LB and HR preserve fossils of early Homo and Paranthropus robustus, Earlier Stone Age lithic artifacts, purported bone digging tools and butchered animal bones. Collectively, this evidence was the first to establish the co-existence of two early Pleistocene hominid species and also led to inferences of plant root harvesting and meat-eating by one or both of those species. P. robustus is the more abundant of the two hominids at Swartrkrans, represented in Member 1 by hundreds of fossils that derive from at least 99 individuals. Thus, Swartkrans Member 1 stands as the world's single largest repository of that extinct species. Here we add to the Member 1 sample of hominid fossils with descriptions of 14 newly discovered specimens.

    Notch signaling pathway plays an integral role in determining cell fates in development. Growing evidence demonstrates that Notch signaling pathway has versatile effects in tumorigenesis depending on the tumor type, grade and stage. Notch signaling pathway is deregulated in some brain tumors. To examine the differential expression of Notch family members (Notch1, 2, 3, 4) in human astrocytomas and medulloblastomas, and to evaluate their roles in the development of both tumor types. Immunohistochemical staining and Western blot analysis were used to detect Notch1, 2, 3, 4 expression in tissue microarray and freshly resected tissue samples of normal brain, astrocytomas and medulloblastomas. Notch family members were not expressed or barely detectable in normal brain tissues. Notch1, 3, 4 were highly expressed but Notch2 was not expressed in astrocytomas. The percentage of immunopositive tumor cells and level of Notch1 expression was increased with tumor grade. In addition, overexpression of Notch2 was detected in medulloblastomas in contrast to low or no expression of Notch1, 3, 4. Differential expression of Notch1, 2, 3, 4 is detected in astrocytomas and medulloblastomas, that may be related to their different roles playing in the development of brain tumors.

    2014-10-01

    Full Text Available This article analyzes comparative price levels of 10 new EU member countries from Central, East, and South-East Europe and discusses their main determinants. A comparison of comparative price levels is logically followed by a comparison of relative GDP per capita in purchasing power parities. Further, the Balassa-Samuelson efect is theoretically explained and empirically tested using a sample of EU27 countries (excluding Luxemburg. The results of simple regression analysis confrm that diferences in comparative price levels can be explained by the diferences in relative GDP per capita in purchasing power parities. Besides the Balassa-Samuelson efect there are, however, many other factors that have an impact on comparative price levels. Tey are related to the lower competitiveness of domestic companies on international markets as the result of such factors as a lower quality of production, inefcient organizational structures and management styles, insufcient marketing and business skills, or a poor approach to international distribution channels.

    Full Text Available Background: Schizophrenia is a severe form of mental disorder which is chronic and disabling in nature. Family members of schizophrenia patients often show negative attitude with higher range of expressed emotion (EE towards their relative as they experience significant stress in coping with caring such patients. Material and methods: The present study was conducted to assess EE of family members of patients with schizophrenia. The study setting was outpatient department and psychiatric ward of Assam Medical College Hospital, Dibrugarh. Hundred schizophrenia patients and 100 family members were included in the study through purposive sampling technique. Tools used in the study were socio-demographic and clinical datasheet of patient, socio-demographic datasheet of family member, and Family Attitude Scale. Results: Majority of family members (79% had low level of EE. Their EE had significant association with age of onset of illness. EE was higher when schizophrenia started before 20 years of patient’s age. Age and marital status of the family members had significant associations with their EE. It increased along with increased age of the family members whereas majority of the younger family members had low level of EE. Married family members had higher level of EE. Conclusion: There is need for psychosocial nursing intervention for the family members of schizophrenia patients to help them cope with their stress.

    (a) To measure the urinary excretion of antineoplastic drugs of three patients during 48 h after the administration of cyclophosphamide (two patients) and 5-fluorouracil (one patient). (b) To evaluate environmental contamination with antineoplastic drugs via excreta of patients in the home setting. (c) To evaluate exposure of family members to antineoplastic drugs by measuring the drugs in their urine during the 48 h after completion of the chemotherapy by the patients. Two patients were administered cyclophosphamide by i.v. bolus injection. One patient was administered 5-fluorouracil by i.v. bolus injection and thereafter immediately administered the same drug by continuous infusion for 46 h. Urine samples from the patients administered cyclophosphamide and their family members, and wipe samples from their home environment, were analysed for the unchanged form of cyclophosphamide. For 5-fluorouracil, the urine samples from the patient and the family member were analysed for the 5-fluorouracil metabolite α-fluoro-β-alanine. Wipe samples were analysed for 5-fluorouracil. Drugs were detected and quantified with gas chromatography in tandem with mass spectroscopy-mass spectroscopy or by high-performance liquid chromatography with ultraviolet-light detection. A total of 35 and 16 urine samples were collected from the three patients and their family members, respectively. The drugs were detected in all samples. Cyclophosphamide was detected at levels of 0.03-7.34 ng/cm(2) in 8 of the 12 wipe samples obtained from the homes of the patients administered cyclophosphamide. For the patient administered 5-fluorouracil, drug levels in his home environment were below the limit of detection. We demonstrated contamination of the home setting and exposure of family members to cyclophosphamide via the excreta of outpatient receiving chemotherapy. Exposure of the family member of the patient administered 5-fluorouracil was also demonstrated. These findings indicate the

  11. Identification of members in the central and outer regions of galaxy clusters

    Serra, Ana Laura

    2012-01-01

    The caustic technique measures the mass of galaxy clusters in both their virial and infall regions and, as a byproduct, yields the list of cluster galaxy members. Here we use 100 galaxy clusters with mass M200>=1E14 Msun/h extracted from a cosmological N-body simulation of a LambdaCDM universe to test the ability of the caustic technique to identify the cluster galaxy members. We identify the true three-dimensional members as the gravitationally bound galaxies. The caustic technique uses the caustic location in the redshift diagram to separate the cluster members from the interlopers. We apply the technique to mock catalogues containing 1000 galaxies in the field of view of 12 Mpc/h on a side at the cluster location. On average, this sample size roughly corresponds to 180 real galaxy members within 3r200, similar to recent redshift surveys of cluster regions. The caustic technique yields a completeness, the fraction of identified true members, fc=0.95 (+- 0.03) within 3r200. The contamination increases from f...

  12. Preferred Team Roles of Construction Team Members in Selected Higher Institution Projects

    2017-05-01

    Full Text Available The study appraises the preferred team role of construction team members in selected higher institution projects in Nigeria, with a view to improving delivery of such projects. The study used purposive sampling technique to select two higher institutions studied and census survey was used in selecting 35 completed construction projects executed by the institutions. A total of 191 questionnaires were distributed to obtain information from construction team members who participated in the selected construction projects. Mean Item Score was used in ranking the preferred team roles of construction team members. The results revealed that the construction team members’ preferred team roles by personal assessment are different from their preferred team roles by other observers’ assessment of individual construction team members. Construction team members have more than one preferred team roles and that the most preferred team role of Quantity surveyors, clients and contractors is resource investigator while the most preferred team role of Architects, Structural/Civil Engineers and Service Engineer is Planter, Implementer/company worker and specialist respectively. The study concluded that a deliberate attempt should be made in determining the preferred team roles of construction team members before co- opting them into a team so as to improve construction projects delivery.

  13. The Switching Decision: Are Members of Superannuation Funds Rational and Informed Investors?

    Directory of Open Access Journals (Sweden)

    Sarath Delpachitra

    2014-10-01

    Full Text Available The recent Cooper Review (Cooper 2010 attempted to address governance, structure, efficiency and operational problems by recommending changes without pinpointing the root causes and systematic design flaws of the Australian Superannuation System. Despite overwhelming evidence that members’ disengagement was a root cause of the problems, little attention was paid to the motivation and background of members to facilitate participation and decision-making. For instance, a very small percentage of members take their role in the superannuation industry seriously. This is evidenced by the fact that a very small percentage of members (2.5% in 2007 actively changed superannuation fund and most new fund members ‘defaulted’ into employer-selected funds (Bateman 2009. This may be that they are serious but lack the ability or time to monitor investments in a way required by a sophisticated system. This paper explores the drivers of switching superannuation funds of those working-age Australians. It also analyses the presentation of fund information to the sample population to examine how members use information in their superannuation decisions. This may add insight to the ways fund information is made available and also to the types of members who may need more protection, support or education.

  14. Family Members' Unique Perspectives of the Family: Examining their Scope, Size, and Relations to Individual Adjustment

    Jager, Justin; Bornstein, Marc H.; Diane, L. Putnick; Hendricks, Charlene

    2012-01-01

    Using the Family Assessment Device (FAD; Epstein, Baldwin, & Bishop, 1983) and incorporating the perspectives of adolescent, mother, and father, this study examined each family member's “unique perspective” or non-shared, idiosyncratic view of the family. To do so we used a modified multitrait-multimethod confirmatory factor analysis that (1) isolated for each family member's six reports of family dysfunction the non-shared variance (a combination of variance idiosyncratic to the individual and measurement error) from variance shared by one or more family members and (2) extracted common variance across each family member's set of non-shared variances. The sample included 128 families from a U.S. East Coast metropolitan area. Each family member's unique perspective generalized across his or her different reports of family dysfunction and accounted for a sizable proportion of his or her own variance in reports of family dysfunction. Additionally, after holding level of dysfunction constant across families and controlling for a family's shared variance (agreement regarding family dysfunction), each family member's unique perspective was associated with his or her own adjustment. Future applications and competing alternatives for what these “unique perspectives” reflect about the family are discussed. PMID:22545933

    2010-01-01

    Nearby late-type stars are excellent targets to look for young objects in stellar associations and moving groups. The study of these groups goes back more than one century ago however, their origin is still misunderstood. Although their existence have been confirmed by statistical studies of large sample of stars, the identification of a group of stars as member of moving groups, is not an easy task, list of members often change with time and most members have been identified by means of kinematics criteria which is not sufficient since many old stars can share the same spatial motion of those stars in moving groups. In this contribution we attempt to identify unambiguous moving groups members, among a sample of nearby-late type stars. High resolution echelle spectra is used to i) derive accurate radial velocities which allow us to study the stars' kinematics and make a first selection of moving groups members; and ii) analyze several age-related properties for young late-type stars (i.e., lithium LiI 6707.8 ...

    SummaryPrincipal component analysis (PCA) applied to hydrochemical data has been used with end-member mixing to characterize groundwater flow to a limited extent, but aspects of this approach are unresolved. Previous similar approaches typically have assumed that the extreme-value samples identified by PCA represent end members. The method presented herein is different from previous work in that (1) end members were not assumed to have been sampled but rather were estimated and constrained by prior knowledge; (2) end-member mixing was quantified in relation to hydrogeologic domains, which focuses model results on major hydrologic processes; (3) a method to select an appropriate number of end members using a series of cluster analyses is presented; and (4) conservative tracers were weighted preferentially in model calibration, which distributed model errors of optimized values, or residuals, more appropriately than would otherwise be the case. The latter item also provides an estimate of the relative influence of geochemical evolution along flow paths in comparison to mixing. This method was applied to groundwater in Wind Cave and the associated karst aquifer in the Black Hills of South Dakota, USA. The end-member mixing model was used to test a hypothesis that five different end-member waters are mixed in the groundwater system comprising five hydrogeologic domains. The model estimated that Wind Cave received most of its groundwater inflow from local surface recharge with an additional 33% from an upgradient aquifer. Artesian springs in the vicinity of Wind Cave primarily received water from regional groundwater flow.

    The purpose of this study was to investigate whether plastic surgeons would perform elective cosmetic surgery on spouses or other family members and how many have done so, the type of procedures, the circumstances under which the surgery took place, and the results. Participants were 465 members of the American Society for Aesthetic Plastic Surgery, representing 30.7 percent of the overall sample pool of 1513 members recruited through anonymous, voluntary participation in an online survey. Approximately half (51.8 percent) were 51 to 65 years old, most were men (91.2 percent), and most were from large urban areas; respondents had been in practice for 1 to 40 years. The plastic surgeons who returned the survey were comfortable performing elective cosmetic procedures on family members, the majority having already done so. Eighty-eight percent reported they would operate on a spouse or other family member, and 83.9 percent reported they already had. The main motivation (67 percent) was their belief that they were the best surgeon for the procedure. The most commonly listed operations were rhinoplasty, abdominoplasty, eyelidplasty, face lift, breast augmentation, and liposuction. Patients included spouses, children, parents, cousins, and in-laws, ranging from teenaged males to women in their 70s. The overwhelming majority (94.2 percent) reported no complications, and 99.5 percent believed the patients were satisfied with their outcome. Survey participants are comfortable with the idea of performing elective cosmetic procedures on family members. Regardless of the invasiveness of the procedure or their relationship with the patient, respondents reported no complications and a high level of patient satisfaction anomalous for any patient-surgeon sample, suggesting that surgeons who operate on family members hold confident opinions of their surgical skills and results.

    Andernach, H

    2009-01-01

    We searched the literature for radio images and fluxes of brightest cluster members (BCMs) in 1169 Abell clusters, selected on the basis of their BM or RS type or on textual notes in the Abell catalog indicating the presence of dominant galaxies. We inspected the images of existing radio surveys (NVSS, SUMSS, FIRST, WENSS, etc.) and used the CATS and VizieR catalog browsers, as well as additional literature, to collect radio fluxes and radio morphologies for 1423 BCMs. We found 578 (41%) of these BCMs with detected radio emission, of which 223 are detected at only a single frequency. Using the survey images and published high-resolution images, we estimated the best available position angle for the innermost radio structure and for the largest angular size of each source. DSS images were used to obtain the orientation of the optical major axis of the outer envelope of the BCMs, and the acute difference angle between major optical and radio axes was derived for 102 objects. Its distribution shows a similar bim...

  16. Multivariate analyses and end-member mixing to characterize karst groundwater flow

    Science.gov (United States)

    Long, A. J.; Valder, J. F.

    2011-12-01

    End-member mixing (EMM) is a simple modeling approach that is used to estimate the mixing proportions of different waters contributing to sampled sites. This approach has advantages for karst aquifers and groundwater in caves because no assumptions need to be made regarding the presence, locations, or dimensions of conduits. Principal component analysis (PCA) applied to hydrochemical data is useful for assessing hydrochemical data to be used in EMM and for determining appropriate constraints on the EMM model. The combination of these two methods has been used to a limited extent to characterize groundwater flow and has excellent potential for further development and application, but aspects of this approach are unresolved. Previous similar approaches typically have assumed that the extreme-value samples identified by PCA represent end members. The approach we present is different from previous work in that (1) end members were not assumed to have been sampled but rather were estimated and constrained by prior knowledge; (2) end-member mixing was quantified in relation to hydrogeologic domains, which focuses model results on major hydrologic processes; (3) a method to select an appropriate number of end members using a series of cluster analyses is presented; and (4) conservative tracers were weighted preferentially in model calibration, which distributed model errors of optimized values, or residuals, more appropriately than otherwise would be the case.

  17. Insider Research with Family Members who have a Member Living with Rare Cancer

    Directory of Open Access Journals (Sweden)

    Jan Foster PhD

    2009-12-01

    Full Text Available In this article the author explores insider research in relation to family members facing a diagnosis of rare cancer, using her experiences as one such family member undertaking doctoral research into journeys similar to hers. The “insider” issue is explored through three realms: the ethical realm, including issues of “fitness” to undertake the research; the methodological realm, including how data are obtained and used; and the trustworthiness realm, including research rigor. The exploration of her insider experiences includes personal challenges in relation to facing familiar emotionally charged experiences, insights gained as a result of her insider status, and her ability to join with participants in ways that might not be possible for an outsider. In the paper the author challenges taken-for-granted assumptions that trustworthiness can be assured only from the position of “objective” researcher. Rather, this analysis places knowledge gained through the processes and products of research as constituted and contextualized.

    Explore the mental health differences of student veterans by sexual orientation. Student service members/veterans (N = 702) from the Fall 2011 National College Health Assessment. Descriptive statistics and 2-sample proportion and mean tests were used to compare mental health characteristics. Student veterans who identify as lesbian, gay, bisexual, or unsure had higher levels of mental health symptoms and treatment. Results suggest a need for continued examination of student service members/veterans as related to disparities in mental health by sexual orientation.

    2016-12-01

    The aims of this study were to estimate the prevalence of smoking among SEPAR members, and their approach to smoking cessation in their patients. An online survey was completed by 640 members (496 pulmonologists, 45 nurses, 34 thoracic surgeons, 37 physiotherapists, and 28 other specialists). Of the members interviewed, 5% confessed that they were smokers: 3.5% pulmonologists; 8.9% nurses; 8.8% thoracic surgeons, and 13.5% physiotherapists. A total of 96% of members assign a lot or quite a lot of importance to setting an example; 98% of members always or often ask their patients about their smoking habit. The most effective anti-smoking intervention, according to 77% of members, is a combination of drugs and psychological support. These results are an indicator of the awareness and commitment of SEPAR members to smoking and its cessation. Copyright © 2016 SEPAR. Publicado por Elsevier España, S.L.U. All rights reserved.

    1984-07-01

    The multivariate statistical techniques of correlation coefficients, factor analysis, and cluster analysis, implemented by computer programs, can be used to process a large data set and produce a summary of relationships between variables and between samples. These techniques were used to find relationships for data on the inorganic constituents of US coals. Three hundred thirty-five whole-seam channel samples from six US coal provinces were analyzed for inorganic variables. After consideration of the attributes of data expressed on ash basis and whole-coal basis, it was decided to perform complete statistical analyses on both data sets. Thirty variables expressed on whole-coal basis and twenty-six variables expressed on ash basis were used. For each inorganic variable, a frequency distribution histogram and a set of summary statistics was produced. These were subdivided to reveal the manner in which concentrations of inorganic constituents vary between coal provinces and between coal regions. Data collected on 124 samples from three stratigraphic groups (Pottsville, Monongahela, Allegheny) in the Appalachian region were studied using analysis of variance to determine degree of variability between stratigraphic levels. Most variables showed differences in mean values between the three groups. 193 references, 71 figures, 54 tables.

  3. Characterization of Clay Minerals and Kerogen in Alberta Oil Sands Geological End Members

    Science.gov (United States)

    Zheng, Limin

    The high degree of variability of oil sands ores can be attributed to a mixture of different geological end members, i.e., estuarine sand, estuarine clay, marine sand and marine clay. This study focused on the mineralogy, especially of clay minerals, and toluene insoluble organic matter, referred to as kerogen, in different oil sands end members. Clays and kerogens will likely have a significant impact on solvent recovery from the gangue following non-aqueous bitumen extraction. The bitumen-free solids were subjected to mineralogical and geochemical analysis. Kerogens were isolated and analyzed by various characterization methods. The types of clays were identified in oriented samples by X-ray diffraction analysis. The nitrogen to carbon ratio in the isolated kerogens is found to be higher than in bitumen. There are more type III kerogens in estuarine samples and more type II kerogens in marine samples.

  4. Characterization of the Bacterial Community Naturally Present on Commercially Grown Basil Leaves: Evaluation of Sample Preparation Prior to Culture-Independent Techniques

    2015-08-01

    Full Text Available Fresh herbs such as basil constitute an important food commodity worldwide. Basil provides considerable culinary and health benefits, but has also been implicated in foodborne illnesses. The naturally occurring bacterial community on basil leaves is currently unknown, so the epiphytic bacterial community was investigated using the culture-independent techniques denaturing gradient gel electrophoresis (DGGE and next-generation sequencing (NGS. Sample preparation had a major influence on the results from DGGE and NGS: Novosphingobium was the dominant genus for three different basil batches obtained by maceration of basil leaves, while washing of the leaves yielded lower numbers but more variable dominant bacterial genera including Klebsiella, Pantoea, Flavobacterium, Sphingobacterium and Pseudomonas. During storage of basil, bacterial growth and shifts in the bacterial community were observed with DGGE and NGS. Spoilage was not associated with specific bacterial groups and presumably caused by physiological tissue deterioration and visual defects, rather than by bacterial growth.

    2016-03-01

    Anchored in the social organization theory of action and change, we use data from a large sample of active-duty Air Force members to examine the direct and indirect influence of social involvement and social responsibility on willingness to seek help in times of need via trust in formal systems and informal supports. Group comparisons are conducted between junior male, junior female, senior male, and senior female service members. The key mediational path in the model for all groups is the connection between social involvement and willingness to seek help via trust in formal systems. These results can inform both unit- and community-level interventions intended to increase the likelihood that active-duty AF members will seek help in times of need.

    Empirical findings characterizing long-term, committed Alcoholics Anonymous (AA) members are limited, particularly among younger members. The authors studied a sample of 266 highly committed attendees (mean age, 27 years) at an annual conference of Young People in Alcoholics Anonymous (YPAA), whose first encounter with AA was 6 years previously. Most (72%) had abused drugs and alcohol, and 36% had never received substance abuse treatment. They now reported a mean duration of abstinence of 44 months and had attended an average of 233 AA meetings in the previous year; 66% had served as AA sponsors, and 92% reported experiencing an AA "spiritual awakening," itself associated with a decreased likelihood of alcohol craving. Scores on AA beliefs, affiliation to other members, and the experience of spiritual awakening were associated with lower depression scores. These findings are discussed to clarify the nature of long-term AA membership.

    Mechanical properties of the tuffaceous rocks within Yucca Mountain are needed for near and far-field modeling of the potential nuclear waste repository. If the mechanical properties are significantly anisotropic (i.e., direction-dependent), a more complex model is required. Relevant data from tuffs tested in earlier studies indicate that elastic and strength properties are anisotropic. This scoping study confirms the elastic anisotropy and concludes some tuffs are transversely isotropic. An approach for sampling and testing the rock to determine the magnitude of the anisotropy is proposed.

    Soil bacterial communities typically exhibit a distribution pattern in which most bacterial species are present in low abundance. Due to the relatively small size of most culture-independent sequencing surveys, a detailed phylogenetic analysis of rare members of the community is lacking. To gain access to the rarely sampled soil biosphere, we analyzed a data set of 13,001 near-full-length 16S rRNA gene clones derived from an undisturbed tall grass prairie soil in central Oklahoma. Rare members of the soil bacterial community (empirically defined at two different abundance cutoffs) represented 18.1 to 37.1% of the total number of clones in the data set and were, on average, less similar to their closest relatives in public databases when compared to more abundant members of the community. Detailed phylogenetic analyses indicated that members of the soil rare biosphere either belonged to novel bacterial lineages (members of five novel bacterial phyla identified in the data set, as well as members of multiple novel lineages within previously described phyla or candidate phyla), to lineages that are prevalent in other environments but rarely encountered in soil, or were close relatives to more abundant taxa in the data set. While a fraction of the rare community was closely related to more abundant taxonomic groups in the data set, a significant portion of the rare biosphere represented evolutionarily distinct lineages at various taxonomic cutoffs. We reason that these novelty and uniqueness patterns provide clues regarding the origins and potential ecological roles of members of the soil's rare biosphere.

    The observations and methods are discussed in detail in Paper I (Rebull et al. 2016, Cat. J/AJ/152/113). Here we simply summarize the main points. Members of the Pleiades were observed in K2 campaign 4, which lasted for 72 days. All of the stars in this sample were observed in the long-cadence (~30 minute exposure) mode. We looked for periods using the Lomb-Scargle (LS; Scargle 1982ApJ...263..835S) approach. For stars of the mass range considered here, the periods that we measure are, by and large, starspot-modulated rotation periods. Spot modulation is the simplest explanation for sinusoidal (or sinusoidal-like) variations where there are changes over an entire orbital phase. We assembled a catalog of literature data for our targets. The most important values obtained from this search are (V-Ks)0 (measured or inferred; see Paper I, Rebull et al. 2016, Cat. J/AJ/152/113) and membership (see Paper I). Cross-identifications between the EPIC number, R.A./decl., and common literature names are in Paper I. Out of the 1020 light curves of candidate Pleiades members from which we started, there are 775 high-confidence members, with 51 more lower-confidence members (for a total of 826 members). Out of those 775 (best members), 716 (92.4%) have at least one measured period that we believe in the overwhelming majority of cases to be a rotation period and due to starspots. Including the lower-confidence members, 759/826 (91.9%) have at least one measured period (see Table2). The period distribution is strongly peaked at P<1day with typical amplitudes of ~0.03mag.

  10. Measurement and comparison of nursing faculty members' critical thinking skills.

    Science.gov (United States)

    Blondy, Laurie C

    2011-03-01

    Nursing faculty members strive to teach students to think critically. It has long been assumed that nursing faculty members are good at critical thinking because they are expected to teach these skills to students, but this assumption has not been well supported empirically. Faculty members question their ability to think critically and are unsure of their skills. The purpose of this study was to address this assumption by measuring nursing faculty members' critical thinking skills and compare the faculty mean score to that of a student norming group, and to the mean scores of other nursing faculty studies. Findings can be used to increase nursing faculty members' understanding of their critical thinking skills, prompt discussion about critical thinking skills, and to help faculty members address concerns and uncertainty about the concept of critical thinking. This study also helps establish an empirical basis for future research.

    This study compared gang versus nongang high school students along measures of self-esteem, racial attitudes, and their self-professed role models. A total of 78 Caucasian (65 nongang and 13 gang members) and 77 African-American students (41 nongang and 36 gang members) participated. Results indicated that gang members had significantly lower levels of self-esteem compared to their nongang peers. All students, regardless of ethnicity, manifested negative racial stereotyping toward racial outgroups; gang members were not more racially prejudiced compared to other students. The role model data revealed that overall, gang members could name fewer role models than did their nongang peers. African-American students who were not gang members were much more likely to mention a parent or teacher as a role model. A regression analysis indicated that the absence of parental or teacher roles models was the best predictor of gang membership. These results are conceptualized within the framework provided by social identity theory.

  12. Additional TWA Members? Spectroscopic verification of kinematically selected TWA candidates

    2002-01-01

    We present spectroscopic measurements of the 23 new candidate members of the TW Hydrae Association from Makarov & Fabricius (2000). Based on Halpha and Li 6708 A strengths together with location on a color-magnitude diagram for Hipparcos TWA candidates, we found only three possible new members (TYC 7760-0835-1, TYC 8238-1462-1, and TYC 8234-2856-1) in addition to the already known member, TWA 19. This eliminated most of the candidates more distant than 100 pc. Three Tycho stars, almost certainly members of the Lower Centaurus Crux association, are the most distant members of the TWA. A claim of isotropic expansion of TWA has to be re-evaluated based on our new results. Generally, one cannot identify new members of a diffuse nearby stellar group based solely on kinematic data. To eliminate interlopers with similar kinematics, spectroscopic verification is essential.

    Researchers have shown inconsistencies in compliance, outcomes and attitudes of surgical team members related to surgical safety checklist briefings. The purpose of this study was to examine surgical circulator and scrub practitioners' perceptions of safety checklist briefings and team member involvement, and to identify potential improvements in the process based on those perceptions. An anonymous survey was conducted with members of the Association of periOperative Registered Nurses (AORN) and the Association of Surgical Technologists (AST). Questions focused on perceptions of checklist briefing efficacy and team member involvement in safety practices. From the 346 usable responses, a third respondent group of self-identified perioperative leaders emerged. Significant results were obtained related to leaders' perceptions, post-procedure briefings and various perceptions of team member involvement. Study results indicate that variances in safety practices continue as perceived by surgical team members thus presenting opportunities for further examination and improvement of processes in reducing surgical errors.

    Research has documented numerous benefits and challenges associated with receipt of hospice care in nursing homes; however, study of this partnership from the perspective of residents' family members has been limited. The purpose of this qualitative investigation was to explore family members' experience with hospice services received in the nursing home setting. Researchers conducted a secondary data analysis of 175 family member interviews using a thematic analytic approach. Findings highlighted the critical role of communication in supporting residents and their family members. Care coordination, support and oversight, and role confusion also impacted family members' experience of hospice care in the nursing home. Efforts directed at enhancing communication and more clearly articulating the roles of members of the health care team are indicated.

    Elongation factor 1α (EF-1α) and elongation factor-like protein (EFL) are considered to be functionally equivalent proteins involved in peptide synthesis. Eukaryotes can be fundamentally divided into 'EF-1α-containing' and 'EFL-containing' types. Recently, EF-1α and EFL genes have been surveyed across the diversity of eukaryotes to explore the origin and evolution of EFL genes. Although the phylum Cercozoa is a diverse group, gene data for either EFL or EF-1α are absent from all cercozoans except chlorarachniophytes which were previously defined as EFL-containing members. Our survey revealed that two members of the cercozoan subphylum Filosa (Thaumatomastix sp. and strain YPF610) are EFL-containing members. Importantly, we identified EF-1α genes from two members of Filosa (Paracercomonas marina and Paulinella chromatophora) and a member of the other subphylum Endomyxa (Filoreta japonica). All cercozoan EFL homologues could not be recovered as a monophyletic group in maximum-likelihood and Bayesian analyses, suggesting that lateral gene transfer was involved in the EFL evolution in this protist assemblage. In contrast, EF-1α analysis successfully recovered a monophyly of three homologues sampled from the two cercozoan subphyla. Based on the results, we postulate that cercozoan EF-1α genes have been vertically inherited, and the current EFL-containing species may have secondarily lost their EF-1α genes.

  16. A Brazilian Marseillevirus Is the Founding Member of a Lineage in Family Marseilleviridae

    Full Text Available In 2003, Acanthamoeba polyphaga mimivirus (APMV was discovered as parasitizing Acanthamoeba. It was revealed to exhibit remarkable features, especially odd genomic characteristics, and founded viral family Mimiviridae. Subsequently, a second family of giant amoebal viruses was described, Marseilleviridae, whose prototype member is Marseillevirus, discovered in 2009. Currently, the genomes of seven different members of this family have been fully sequenced. Previous phylogenetic analysis suggested the existence of three Marseilleviridae lineages: A, B and C. Here, we describe a new member of this family, Brazilian Marseillevirus (BrMV, which was isolated from a Brazilian sample and whose genome was fully sequenced and analyzed. Surprisingly, data from phylogenetic analyses and comparative genomics, including mean amino acid identity between BrMV and other Marseilleviridae members and the analyses of the core genome and pan-genome of marseilleviruses, indicated that this virus can be assigned to a new Marseilleviridae lineage. Even if the BrMV genome is one of the smallest among Marseilleviridae members, it harbors the second largest gene content into this family. In addition, the BrMV genome encodes 29 ORFans. Here, we describe the isolation and genome analyses of the BrMV strain, and propose its classification as the prototype virus of a new lineage D within the family Marseilleviridae.

    In 2003, Acanthamoeba polyphaga mimivirus (APMV) was discovered as parasitizing Acanthamoeba. It was revealed to exhibit remarkable features, especially odd genomic characteristics, and founded viral family Mimiviridae. Subsequently, a second family of giant amoebal viruses was described, Marseilleviridae, whose prototype member is Marseillevirus, discovered in 2009. Currently, the genomes of seven different members of this family have been fully sequenced. Previous phylogenetic analysis suggested the existence of three Marseilleviridae lineages: A, B and C. Here, we describe a new member of this family, Brazilian Marseillevirus (BrMV), which was isolated from a Brazilian sample and whose genome was fully sequenced and analyzed. Surprisingly, data from phylogenetic analyses and comparative genomics, including mean amino acid identity between BrMV and other Marseilleviridae members and the analyses of the core genome and pan-genome of marseilleviruses, indicated that this virus can be assigned to a new Marseilleviridae lineage. Even if the BrMV genome is one of the smallest among Marseilleviridae members, it harbors the second largest gene content into this family. In addition, the BrMV genome encodes 29 ORFans.

    To explore the experiences of family members of patients treated with extracorporeal membrane oxygenation. Sudden onset of an unexpected and severe illness is associated with an increased stress experience of family members. Only one study to date has explored the experience of family members of patients who are at high risk of dying and treated with extracorporeal membrane oxygenation. A qualitative descriptive research design was used. A total of 10 family members of patients treated with extracorporeal membrane oxygenation were recruited through a convenient sampling approach. Data were collected using open-ended semi-structured interviews. A six-step process was applied to analyse the data thematically. Four criteria were employed to evaluate methodological rigour. Family members of extracorporeal membrane oxygenation patients experienced psychological distress and strain during and after admission. Five main themes (Going Downhill, Intensive Care Unit Stress and Stressors, Carousel of Roles, Today and Advice) were identified. These themes were explored from the four roles of the Carousel of Roles theme (decision-maker, carer, manager and recorder) that participants experienced. Nurses and other staff involved in the care of extracorporeal membrane oxygenation patients must pay attention to individual needs of the family and activate all available support systems to help them cope with stress and strain. An information and recommendation guide for families and staff caring for extracorporeal membrane oxygenation patients was developed and needs to be applied cautiously to the individual clinical setting. © 2016 John Wiley & Sons Ltd.

    Acton, Gayle J; Winter, Mary A

    2002-01-01

    This chapter reviews 73 published and unpublished research reports of interventions for family members caring for an elder with dementia by nurse researchers and researchers from other disciplines. Reports were identified through searches of MEDLINE, CINAHL, Social Science Index, PsycINFO, ERIC, Social Work Abstracts, American Association of Retired Persons database, CRISP index of the National Institutes of Health, Cochrane Center database, and Dissertation Abstracts using the following search terms: caregiver, caregiving, dementia, Alzheimer's, intervention study, evaluation study, experimental, and quasi-experimental design. Additional keywords were used to narrow or expand the search as necessary. All nursing research was included in the review and nonnursing research was included if published between 1991 and 2001. Studies were included if they used a design that included a treatment and control group or a one-group, pretest-posttest design (ex post facto designs were included if they used a comparison group). Key findings show that approximately 32% of the study outcomes (e.g., burden, depression, knowledge) were changed after intervention in the desired direction. In addition, several problematic issues were identified including small, diverse samples; lack of intervention specificity; diversity in the length, duration, and intensity of the intervention strategies; and problematic outcome measures.

  7. A spectroscopy study of nearby late-type stars, possible members of stellar kinematic groups

    Nearby late-type stars are excellent targets for seeking young objects in stellar associations and moving groups. The origin of these structures is still misunderstood, and lists of moving group members often change with time and also from author to author. Most members of these groups have been identified by means of kinematic criteria, leading to an important contamination of previous lists by old field stars. We attempt to identify unambiguous moving group members among a sample of nearby-late type stars by studying their kinematics, lithium abundance, chromospheric activity, and other age-related properties. High-resolution echelle spectra ($R \\sim 57000$) of a sample of nearby late-type stars are used to derive accurate radial velocities that are combined with the precise Hipparcos parallaxes and proper motions to compute galactic-spatial velocity components. Stars are classified as possible members of the classical moving groups according to their kinematics. The spectra are also used to study several a...

    One prominent approach in the exploration of the variations in project team performance has been to study two components of the aggregate personalities of the team members: conscientiousness and agreeableness. A second line of research, known as self-categorisation theory, argues that identifying as team members and the team's performance norms should substantially influence the team's performance. This paper explores the influence of both these perspectives in university software engineering project teams. Eighty students worked to complete a piece of software in small project teams during 2007 or 2008. To reduce limitations in statistical analysis, Monte Carlo simulation techniques were employed to extrapolate from the results of the original sample to a larger simulated sample (2043 cases, within 319 teams). The results emphasise the importance of taking into account personality (particularly conscientiousness), and both team identification and the team's norm of performance, in order to cultivate higher levels of performance in student software engineering project teams.

    2006-07-01

    The 3 studies presented here introduce a new measure of the individual-difference form of collectivism. Psychological collectivism is conceptualized as a multidimensional construct with the following 5 facets: preference for in-groups, reliance on in-groups, concern for in-groups, acceptance of in-group norms, and prioritization of in-group goals. Study 1 developed and tested the new measure in a sample of consultants. Study 2 cross-validated the measure using an alumni sample of a Southeastern university, assessing its convergent validity with other collectivism measures. Study 3 linked scores on the measure to 4 dimensions of group member performance (task performance, citizenship behavior, counterproductive behavior, and withdrawal behavior) in a computer software firm and assessed discriminant validity using the Big Five. The results of the studies support the construct validity of the measure and illustrate the potential value of collectivism as a predictor of group member performance.

    Gang activity and membership were noted to be significantly related to financial rewards. As such, gang membership and gang activity should also be understood from an economic perspective. In this article, Pierre Bourdieu's framework of capital is used to analyze two separate samples of Latino and Asian gang members. Stark contrasts in socioeconomic backgrounds are recorded among the two samples of gang members, and gang membership and activities are also noticeably dissimilar. Accessibility to economic, cultural, and social capital is argued to affect gang membership and activities. The results suggest that the availability of legitimate and illegitimate capital greatly affects the trajectory and the length of gang involvement. Also, gangs provide significant material and social capital for the respondents of the study. PMID:19578563

  17. A Mars Sample Return Sample Handling System

    Science.gov (United States)

    Wilson, David; Stroker, Carol

    2013-01-01

    We present a sample handling system, a subsystem of the proposed Dragon landed Mars Sample Return (MSR) mission [1], that can return to Earth orbit a significant mass of frozen Mars samples potentially consisting of: rock cores, subsurface drilled rock and ice cuttings, pebble sized rocks, and soil scoops. The sample collection, storage, retrieval and packaging assumptions and concepts in this study are applicable for the NASA's MPPG MSR mission architecture options [2]. Our study assumes a predecessor rover mission collects samples for return to Earth to address questions on: past life, climate change, water history, age dating, understanding Mars interior evolution [3], and, human safety and in-situ resource utilization. Hence the rover will have "integrated priorities for rock sampling" [3] that cover collection of subaqueous or hydrothermal sediments, low-temperature fluidaltered rocks, unaltered igneous rocks, regolith and atmosphere samples. Samples could include: drilled rock cores, alluvial and fluvial deposits, subsurface ice and soils, clays, sulfates, salts including perchlorates, aeolian deposits, and concretions. Thus samples will have a broad range of bulk densities, and require for Earth based analysis where practical: in-situ characterization, management of degradation such as perchlorate deliquescence and volatile release, and contamination management. We propose to adopt a sample container with a set of cups each with a sample from a specific location. We considered two sample cups sizes: (1) a small cup sized for samples matching those submitted to in-situ characterization instruments, and, (2) a larger cup for 100 mm rock cores [4] and pebble sized rocks, thus providing diverse samples and optimizing the MSR sample mass payload fraction for a given payload volume. We minimize sample degradation by keeping them frozen in the MSR payload sample canister using Peltier chip cooling. The cups are sealed by interference fitted heat activated memory

    Dynamic posture testing was conducted on the science crew of the Spacelab-1 mission on a single axis linear motion platform. Tests took place in pre- and post-flight sessions lasting approximately 20 min each. The pre-flight tests were widely spaced over the several months prior to the mission while the post-flight tests were conducted over the first, second, fourth, and sixth days after landing. Two of the crew members were also tested on the day of landing. Consistent with previous postural testing conducted on flight crews, these crew members were able to complete simple postural tasks to an acceptable level even in the first few hours after landing. Our tests were designed to induce dynamic postural responses using a variety of stimuli and from these responses, evaluate subtle changes in the postural control system which had occurred over the duration of the flight. Periodic sampling post-flight allowed us to observe the time course of readaptation to terrestrial life. Our observations of hip and shoulder position, when subjected to careful analysis, indicated modification of the postural response from pre- to post-flight and that demonstrable adjustments in the dynamic control of their postural systems were taking place in the first few days after flight. For transient stimuli where the platform on which they were asked to stand quickly moved a few centimeters fore or aft then stopped, ballistic or open loop 'programs' would closely characterize the response. During these responses the desired target position was not always achieved and of equal importance not always properly corrected some 15 seconds after the platform ceased to move. The persistent observation was that the subjects had a much stronger dependence on visual stabilization post-flight than pre-flight. This was best illustrated by a slow or only partial recovery to an upward posture after a transient base-of-support movement with eyes open. Postural responses to persistent wideband pseudorandom

    This report describes the way EU Member States have transposed the sustainability and chain of custody requirements for biofuels as laid down in the Renewable Energy Directive (RED) and Fuel Quality Directive (FQD). In the assessment of Member States' implementation, the report mainly focuses on effectiveness and administrative burden. Have Member States transposed the Directives in such a way that compliance with the sustainability criteria can be ensured as effectively as possible? To what extent does the Member States' implementation lead to unnecessary administrative burden for economic operators in the (bio)fuel supply chain? The report focuses specifically on the transposition of the sustainability and chain of custody requirements, not on the target for renewables on transport. This means that for example the double counting provision is not included as part of the scope of this report. This report starts with an introduction covering the implementation of the Renewable Energy (and Fuel Quality) Directive into national legislation, the methodology by which Member States were assessed against effectiveness and administrative burden and the categorisation of Member State's national systems for RED-implementation (Chapter 1). The report continues with a high level description of each Member State system assessed (Chapter 2). Following this, the report includes analysis of the Member States on the effectiveness and administrative burden of a number of key ('major') measures (Chapter 3). The final chapter presents the conclusions and recommendations (Chapter 4)

  15. Vertical load capacities of roof truss cross members

    Institute of Scientific and Technical Information of China (English)

    Gearhart David F.; Mohamed Khaled Morsy

    2016-01-01

    Trusses used for roof support in coal mines are constructed of two grouted bolts installed at opposing forty-five degree angles into the roof and a cross member that ties the angled bolts together. The load on the cross member is vertical, which is transverse to the longitudinal axis, and therefore the cross member is loaded in the weakest direction. Laboratory tests were conducted to determine the vertical load capacity and deflection of three different types of cross members. Single-point load tests, with the load applied in the center of the specimen and double-point load tests, with a span of 2.4 m, were con-ducted. For the single-point load configuration, the yield of the 25 mm solid bar cross member was nom-inally 98 kN of vertical load, achieved at 42 cm of deflection. For cable cross members, yield was not achieved even after 45 cm of deflection. Peak vertical loads were about 89 kN for 17 mm cables and 67 kN for the 15 mm cables. For the double-point load configurations, the 25 mm solid bar cross mem-bers yielded at 150 kN of vertical load and 25 cm of deflection.

    The collective behaviors of community members for dynamic social networks are significant for understanding evolution features of communities. In this Letter, we empirically investigate the evolution properties of the new community members for dynamic networks. Firstly, we separate data sets into different slices, and analyze the statistical properties of new members as well as communities they joined in for these data sets. Then we introduce a parameter φ to describe community evolution between different slices and investigate the dynamic community properties of the new community members. The empirical analyses for the Facebook, APS, Enron and Wiki data sets indicate that both the number of new members and joint communities increase, the ratio declines rapidly and then becomes stable over time, and most of the new members will join in the small size communities that is s ≤ 10. Furthermore, the proportion of new members in existed communities decreases firstly and then becomes stable and relatively small for these data sets. Our work may be helpful for deeply understanding the evolution properties of community members for social networks.

    Johannes, Christian; Goedecke, Wolfgang; Antonopoulos, Alexandra; Obe, Günter; Horstmann, Markus

    High energy radiation is a major risk factor in manned space missions. Astronauts and cosmonauts are exposed to ionising radiations of cosmic and solar origin, while on the Earth's surface people are well protected by the atmosphere and a deflecting magnetic field. There are now data available describing the dose and the quality of ionising radiation on-board of the International Space Station (ISS). The effect of the increased radiation dose on mutation rates of ISS crew members are hard to predict. Therefore, direct measurements of mutation rates are required.The analysis of chromosomal aberrations in peripheral blood lymphocytes is a well established method to measure radiation-induced mutations. We present data of chromosome aberration analyses from lymphocyte metaphase spreads of ISS crew members participating in short term (10-14 days) or long term (6 months) missions. From each subject we received two blood samples. The first sample was drawn about 10 days before launch and a second sample was drawn within 3 days after return from their flights. From lymphocyte cultures metaphase plates were prepared on glass slides. Metaphases were Giemsa stained or hybridised using multicolour FISH probes. All types of chromosome changes were scored in pre-flight and post-flight blood samples and the mutation rates were compared. Results obtained in chromosomal studies on long-term flight crew members showed pronounced inter-individual differences in the response to cosmic radiation exposure. Overall significant elevations of typical radiation induced aberrations, i.e., dicentric chromosomes and reciprocal translocations have been observed in long-term crew members. Our data indicate no elevation of mutation rates due to short-term stays on-board the ISS.

    1992-01-01

    An active damping augmentation approach using active members in a structural system is described. The problem of maximizing the vibration damping in a lightly damped structural system is considered using the analogy of impedance matching between the load and source impedances in an electrical network. The proposed active damping augmentation approach therefore consists of finding the desired active member impedances that maximize the vibration damping, and designing a feedback control in order to achieve desired active member impedances. This study uses a bridge feedback concept that feeds back a combination of signals from sensors of the axial force and relative velocity across the active member to realize the desired active member impedance. The proposed active damping augmentation approach and bridge feedback concept were demonstrated on a three-longeron softly suspended truss structure.

    Full Text Available Introduction: Teaching and training are the basic responsibly of a faculty member. One of the fundamental problems of education in the universities is not having a criterion to identify the effective teaching styles. The aim of this study was to determine Grasha teaching method among the faculty Members in Shiraz Medical School. Methods: this descriptive, cross- sectional study was done on 100 faculty members who were selected by census sampling method. Data collection method was Grasha questionnaire which contains 40 questions in 5 sections. Data were analyzed by SPSS 18. Results: All questionnaires were completed. The age range was from 32 to 65 and the mean age was 46. 57% were male. There were 27 PhD, 35 specialists and 38 subspecialists. The highest average score belonged to “Expert” method (2/66±0/55 and the lowest to “Personal” (2± 0/76. 96% of the academic staffs were inclined to “Expert“ method and %97, %83, %78, %80 to “Formal", “Personal", “Delegator“ and “Facilitating“ methods, respectively. There was no significant difference between male and female, but in “Expert” method, the average of females was superior. %77 was under 50 years and %23 over 50. There was no significant difference between elder and younger academic members. No significant difference was found in terms of university degree. Conclusion: This study suggested academic members are inclined to use "Expert” and Delegator methods. Therefore, it is necessary for the academic members to choose a method which creates intellectual excitement among the students through the clarity of teaching content and understanding among individuals that increase the efficiency of their methods.

    2010-07-01

    We present results from our continuing program to identify new, low-mass, members of the nearby young moving groups (NYMGs) using a proper motion selection algorithm and various observational techniques. We have three goals: (1) to provide high priority targets for exoplanet searches by direct imaging, (2) to complete the census of the membership in the NYMGs down to ~0.1 M sun, and thus (3) provide a well-characterized sample of nearby (median distances at least twice as close as the Taurus and Ophiuchus star-forming regions), young (8-50 Myr) stars for detailed study of their physical properties and multiplicity. Our program proceeds as follows: we apply the selection algorithm to a proper motion catalog where initial selection cuts of candidate members are based on the mean motion of known NYMG members and the proper motions and photometric distances of the candidates. NYMG membership is investigated further using possible signs of youth, including Hα emission and X-ray flux, and then verified through radial velocity measurements. We identify TYC 1766-1431-1 (M3), TYC 1208-468-1 and 2 (K3), TYC 7558-655-1 (K5), and PM I04439+3723W and E (M3) as likely members of the β Pictoris moving group (BPMG) and TYC 1741-2117-1N and S (K7), TYC 1752-63-1 (K7), TYC 523-573-1 (K7), and TYC 4943-192-1 (M0) as likely members of the AB Doradus moving group (ABDMG). We also rule out the membership of several BPMG and ABDMG candidates. To date our program has identified 16 new NYMG members of spectral type K3 or later.

    There are indications that livestock-associated MRSA CC398 has a reduced human-to-human transmissibility, limiting its impact on public health and justifying modified control measures. This study determined the transmissibility of MRSA CC398 from livestock veterinarians to their household members in the community as compared to MRSA non-CC398 strains. A one-year prospective cohort study was performed to determine the presence of MRSA CC398 in four-monthly nasal and oropharyngeal samples of livestock veterinarians (n  =  137) and their household members (n  =  389). In addition, a cross-sectional survey was performed to detect the presence of MRSA non-CC398 in hospital derived control patients (n  =  20) and their household members (n  =  41). Staphylococcus aureus isolates were genotyped by staphylococcal protein A (spa) typing and multiple-locus variable-number tandem repeat analysis (MLVA). Mean MRSA CC398 prevalence over the study period was 44% (range 41.6–46.0%) in veterinarians and 4.0% (range 2.8–4.7%) in their household members. The MRSA CC398 prevalence in household members of veterinarians was significantly lower than the MRSA non-CC398 prevalence in household members of control patients (PRR 6.0; 95% CI 2.4–15.5), indicating the reduced transmissibility of MRSA CC398. The impact of MRSA CC398 appears to be low at the moment. However, careful monitoring of the human-to-human transmissibility of MRSA CC398 remains important. PMID:25062364

    The decision to gather information should take into account both the value of information and its accrual costs in time, energy and money. Here we explore how people balance the monetary costs and benefits of gathering additional information in a perceptual-motor estimation task. Participants were rewarded for touching a hidden circular target on a touch-screen display. The target’s center coincided with the mean of a circular Gaussian distribution from which participants could sample repeatedly. Each “cue” — sampled one at a time — was plotted as a dot on the display. Participants had to repeatedly decide, after sampling each cue, whether to stop sampling and attempt to touch the hidden target or continue sampling. Each additional cue increased the participants’ probability of successfully touching the hidden target but reduced their potential reward. Two experimental conditions differed in the initial reward associated with touching the hidden target and the fixed cost per cue. For each condition we computed the optimal number of cues that participants should sample, before taking action, to maximize expected gain. Contrary to recent claims that people gather less information than they objectively should before taking action, we found that participants over-sampled in one experimental condition, and did not significantly under- or over-sample in the other. Additionally, while the ideal observer model ignores the current sample dispersion, we found that participants used it to decide whether to stop sampling and take action or continue sampling, a possible consequence of imperfect learning of the underlying population dispersion across trials.

    1992-01-01

    The goal of this Phase 2 Small Business Innovative Research (SBIR) project was to determine the technical feasibility of developing magnetostrictive active members for use as truss elements in space structures. Active members control elastic vibrations of truss-based space structures and integrate the functions of truss structure element, actively controlled actuator, and sensor. The active members must control structural motion to the sub-micron level and, for many proposed space applications, work at cryogenic temperatures. Under this program both room temperature and cryogenic temperature magnetostrictive active members were designed, fabricated, and tested. The results of these performance tests indicated that room temperature magnetostrictive actuators feature higher strain, stiffness, and force capability with lower amplifier requirements than similarly sized piezoelectric or electrostrictive active members, at the cost of higher mass. Two different cryogenic temperature magnetostrictive materials were tested at liquid nitrogen temperatures, both with larger strain capability than the room temperature magnetostrictive materials. The cryogenic active member development included the design and fabrication of a cryostat that allows operation of the cryogenic active member in a space structure testbed.

    To provide high-quality and effective cancer care, problems and unmet needs of family members during their relatives' hospitalisation have to be identified as well. The aims were to determine how needs of family members of patients with terminal cancer are met and to analyse factors that influence them. The needs were assessed with the Family Inventory of Needs. Each item (n = 20) represents one need of family members, for which the importance and satisfaction are rated. The study comprised 270 family members of hospitalised advanced cancer patients staying in the University Hospital Ostrava who were receiving palliative care. The family members preferred sufficient basic information and patient comfort. The unmet needs were support of hope (73%) and provision of information (65%). The unmet needs were more frequently identified by women, individuals with lower education, younger persons, unemployed, patients' children and family members of patients with generally unfavourable health status (P family members may improve their quality of life.

    Combining the two statistical techniques of network sampling and adaptive sampling, this book illustrates the advantages of using them in tandem to effectively capture sparsely located elements in unknown pockets. It shows how network sampling is a reliable guide in capturing inaccessible entities through linked auxiliaries. The text also explores how adaptive sampling is strengthened in information content through subsidiary sampling with devices to mitigate unmanageable expanding sample sizes. Empirical data illustrates the applicability of both methods.

    Many returning OIF/OEF/OND Veterans are seeking higher education in an effort to develop a meaningful career and financial stability. Evidence suggests that student service members/veterans (SSM/Vs) are experiencing less academic success than other students. The purpose of this review is to identify the unique challenges of SSM/Vs and evaluate current campus efforts to facilitate their retention and academic performance. With a focus on SSM/Vs attending colleges and universities, we obtained 57 peer-reviewed and 73 gray literature records published between 2001 and 2015. The current SSM/V literature contains an abundance of gray literature, and the empirical research tends to be limited by cross-sectional design and small sample sizes. SSM/Vs encounter significant personal and environmental challenges when transitioning from the military to college campuses. A variety of services have been developed to address the needs of the SSM/V population, but the efficacy of these services remains largely unknown. In conclusion, there is a clear need to provide education to faculty, students, and staff regarding the experiences of SSM/Vs. Efforts to enhance screening for, availability of, and SSM/V engagement in mental health services would also be beneficial, as would improved availability of and SSM/V access to academic support. All future programs designed to address the unique challenges of SSM/Vs in the academic environment should also be systematically implemented and evaluated.

    2013-10-01

    The ongoing wars in Afghanistan and Iraq have posed a number of reintegration challenges to service members. Much of the research focuses on those service members experiencing psychological problems and being treated at the VA. In this article, we contend that much of the distress service members experience occurs following deployment and is a consequence of the difficulties encountered during their efforts to successfully reintegrate into their families and communities. We propose a new conceptual framework for intervening in this reintegration distress that is psycho-educational in nature as well as a new delivery model for providing such services. An example of this new intervention framework is presented.

    2011-02-01

    As surgery needs have increased, the traditional surgical team has expanded to include personnel from radiology and perfusion services. A new surgical team member, the intraoperative monitoring technician, is needed to perform intraoperative monitoring during procedures that carry a higher risk of central and peripheral nerve injury. Including the intraoperative monitoring technician on the surgical team can create challenges, including surgical delays and anesthesia care considerations. When the surgical team members, including the surgeon, anesthesia care provider, and circulating nurse, understand and facilitate this new staff member's responsibilities, the technician is able to perform monitoring functions that promote the smooth flow of the surgical procedure and positive patient outcomes.

    1995-01-01

    The invention is a band hinge for flexibly connecting the temple member to the lens frame thereby preventing damage from inadvertent pressure or cyclic wear. A distinguishing feature of the invention is the use of a band hinge that holds together the temple member and the lens frame without the use of a pin or screw hinging mechanism. The invention allows for a high degree of freedom of movement for the temple member with respect to the lens frame which will prevent most forms of damages to the glasses from these types of events.

    Albert John Sargent

    2013-10-01

    Full Text Available Objective: Approximately 260,000 of youth in the United States are gang-affiliated. There is a paucity of data available to identify the prevalence of mental health disorders in this population. Gang members share many of the features of “at risk” or juvenile justice involved youth who deny gang membership. The authors identified rates of psychiatric disorders within a juvenile justice population delineated in three categories: gang members, friends of gang members, and non-gang members. Methods: A retrospective review of records obtained by a juvenile probation department. A large detention center conducted mental health screenings on 7,615 youth aged 13–17. The mental health screenings were performed by either a master level or doctoral level mental health professional. Odds ratios were computed as an effect size for gender, race/ethnic differences, and gang-membership associations with self-reported psychiatric and substance use disorders. Logistic regression was used to evaluate the risk for psychiatric and substance use disorders among gang-members and friends of gang members. Diagnostic information was generated through a clinical interview and flexible battery. Results: Of the 7,615 youth in this study, ~50% had contact with gangs; 11% were self-identified gang-members, and 38% acknowledged having at least one friendship with a gang member. Similar to other studies, being male was a risk-factor for gang-membership (2.31 odds. In this multi-racial and ethnic study, Latinos had a greater affiliation with gang membership and association with gang members as friends (1.44 odds. Gang members were found to have increased rates of post-traumatic stress disorder (1.77 odds, current substance abuse (2.58 odds, oppositional defiant disorder, (1.24 odds and conduct disorder (4.05 odds; however, they were less likely to have an adjustment disorder than non-gang members (0.70 odds. Conclusions: Juveniles who received a mental health assessment

  12. One member, two leaders: extending leader-member exchange theory to a dual leadership context.

    Science.gov (United States)

    Vidyarthi, Prajya R; Erdogan, Berrin; Anand, Smriti; Liden, Robert C; Chaudhry, Anjali

    2014-05-01

    In this study, we develop and test a model that extends leader-member exchange (LMX) theory to a dual leadership context. Drawing upon relative deprivation theory, we assert that when employees work for 2 leaders, each relationship exists within the context of the other relationship. Thus, the level of alignment or misalignment between the 2 relationships has implications for employees' job satisfaction and voluntary turnover. Employing polynomial regression on time-lagged data gathered from 159 information technology consultants nested in 26 client projects, we found that employee outcomes are affected by the quality of the relationship with both agency and client leaders, such that the degree of alignment between the 2 LMXs explained variance in outcomes beyond that explained by both LMXs. Results also revealed that a lack of alignment in the 2 LMXs led to asymmetric effects on outcomes, such that the relationship with agency leader mattered more than the relationship with one's client leader. Finally, frequency of communication with the agency leader determined the degree to which agency LMX affected job satisfaction in the low client LMX condition.

    2016-01-01

    Members of the Marseilleviridae family are large DNA viruses with icosahedral particle structures that infect Acanthamoeba cells. The first Marseillevirus to be discovered was isolated in 2009. Since then, several other members of the Marseilleviridae family have been reported, including Lausannevirus, Senegalvirus, Cannes 8 virus, Insectomime virus, Tunisvirus, Melbournevirus, Port-Miou virus, and Brazilian Marseillevirus, which have been isolated from Europe, Africa, Australia, and South America. The morphological and genomic properties of a new Marseilleviridae family member, Tokyovirus, discovered in a water/soil sample from a Japanese river in Tokyo, were described in the present study. Tokyovirus possesses icosahedral particles of up to 200 nm in diameter, as revealed by a transmission electron microscopy (TEM) analysis, which form a giant virion factory in Acanthamoeba cells. A preliminary genome analysis predicted 487 coding sequences. A dot plot analysis and phylogenetic analysis using family B DNA polymerase, proliferating cell nuclear antigen (PCNA), and DNA-directed RNA polymerase alpha subunit genes revealed that Tokyovirus shares similarities with Marseillevirus, Melbournevirus, and Cannes 8 virus (Marseilleviridae subclade A), but not with Lausannevirus and Port-Miou virus (subclade B), Tunisvirus and Insectomime virus (subclade C), or Brazilian Marseillevirus (subclade D), suggesting that Tokyovirus has evolved separately from the previously described Marseilleviridae members.

    2015-04-01

    Although personal electronic devices, such as mobile phones, computers, and tablets, increasingly are being leveraged as vehicles for health in the civilian world, almost nothing is known about personal technology use in the U.S. military. In 2012 we conducted a unique survey of personal technologies used by U.S. military service members. However, with the rapidly growing sophistication of personal technology and changes in consumer habits, that knowledge must be continuously updated to be useful. Accordingly, we recently surveyed new samples of active duty service members, National Guard and Reserve, and veterans. We collected data by online surveys in 2013 from 239 active, inactive, and former service members. Online surveys were completed in-person via laptop computers at a large military installation and remotely via Web-based surveys posted on the Army Knowledge Online Web site and on a Defense Center Facebook social media channel. We measured high rates of personal technology use by service members at home across popular electronic media. The most dramatic change since our earlier survey was the tremendous increase in mobile phone use at home for a wide variety of purposes. Participants also reported moderate non-work uses of computers and tablets while on recent deployment to Iraq and Afghanistan, but almost no mobile phone use, ostensibly because of military restrictions in the war zone. These latest results will enable researchers and technology developers target their efforts on the most promising and popular technologies for psychological health in the military.

    2017-06-23

    Information and communication technologies (ICTs) are increasingly recognized as having an important role in the delivery of mental health services for youth. Recent studies have evaluated young people's access and use of technology, as well as their perspectives on using technology to receive mental health information, services, and support; however, limited attention has been given to the perspectives of family members in this regard. The aim of this study was to explore the perspectives of family members on the use of ICTs to deliver mental health services to youth within the context of specialized early intervention for a first-episode psychosis (FEP). Six focus groups were conducted with family members recruited from an early intervention program for psychosis. Twelve family members participated in the study (target sample was 12-18, and recruitment efforts took place over the duration of 1 year). A 12-item semistructured focus group guide was developed to explore past experiences of technology and recommendations for the use of technology in youth mental health service delivery. A qualitative thematic analysis guided the identification and organization of common themes and patterns identified across the dataset. Findings were organized by the following themes: access and use of technology, potential negative impacts of technology on youth in recovery, potential benefits of using technology to deliver mental health services to youth, and recommendations to use technology for (1) providing quality information in a manner that is accessible to individuals of diverse socioeconomic backgrounds, (2) facilitating communication with health care professionals and services, and (3) increasing access to peer support. To our knowledge, this is among the first (or the first) to explore the perspectives of family members of youth being treated for FEP on the use of technology for mental health care. Our results highlight the importance of considering diverse experiences

    The caustic technique measures the mass of galaxy clusters in both their virial and infall regions and, as a byproduct, yields the list of cluster galaxy members. Here we use 100 galaxy clusters with mass M{sub 200} {>=} 10{sup 14} h {sup -1} M{sub Sun} extracted from a cosmological N-body simulation of a {Lambda}CDM universe to test the ability of the caustic technique to identify the cluster galaxy members. We identify the true three-dimensional members as the gravitationally bound galaxies. The caustic technique uses the caustic location in the redshift diagram to separate the cluster members from the interlopers. We apply the technique to mock catalogs containing 1000 galaxies in the field of view of 12 h {sup -1} Mpc on a side at the cluster location. On average, this sample size roughly corresponds to 180 real galaxy members within 3r{sub 200}, similar to recent redshift surveys of cluster regions. The caustic technique yields a completeness, the fraction of identified true members, f{sub c} = 0.95 {+-} 0.03, within 3r{sub 200}. The contamination, the fraction of interlopers in the observed catalog of members, increases from f{sub i}=0.020{sup +0.046}{sub -0.015} at r{sub 200} to f{sub i}=0.08{sup +0.11}{sub -0.05} at 3r{sub 200}. No other technique for the identification of the members of a galaxy cluster provides such large completeness and small contamination at these large radii. The caustic technique assumes spherical symmetry and the asphericity of the cluster is responsible for most of the spread of the completeness and the contamination. By applying the technique to an approximately spherical system obtained by stacking the individual clusters, the spreads decrease by at least a factor of two. We finally estimate the cluster mass within 3r{sub 200} after removing the interlopers: for individual clusters, the mass estimated with the virial theorem is unbiased and within 30% of the actual mass; this spread decreases to less than 10% for the spherically

    2007-01-01

    It is well known that in most cases, a reference is necessary for structural health diagnosis, and it is very difficult to obtain such a reference for a given structure. In this paper, a clan member signal method (CMSM) is proposed for use in structures consisting of groups (or clans) that have the same geometry, i.e., the same cross section and length, and identical boundary conditions. It is expected that signals measured on any undamaged member in a clan after an event could be used as a reference for any other members in the clan. To verify the applicability of the proposed method, a steel truss model is tested and the results show that the CMSM is very effective in detecting local damage in structures composed of identical slender members.

    Full Text Available The implementation of the management strategy for increasing the competitiveness of modern organizations is more effective if it is correlated with the organizational communication strategy. Team communication of an organization must be an agile one, its agility depending decisively on the way it was constituted, the assigned role for each team member, the statuses etc. A valuation of all skills and abilities of each member of the communication team is therefore required to harmonize and integrate the team into the overall structure of the company. The objective of the paper is to identify the extent to which the formal role of each team member is the same (almost the same with the role determined by applying the Belbin test. The results of the research are prerequisites for development of measures for individual professional development and integration /reintegration of team members in order to increase agility.

    Full Text Available This exploratory research paper investigated the coping strategies of families of hospitalized psychiatric patients and identified their positive and negative coping strategies. In this paper, the coping strategies of 45 family members were examined using a descriptive, correlational, mixed method research approach. Guided by the Neuman Systems Model and using the Family Crisis Oriented Personal Evaluation Scales and semistructured interviews, this paper found that these family members used more emotion-focused coping strategies than problem-focused coping strategies. The common coping strategies used by family members were communicating with immediate family, acceptance of their situation, passive appraisal, avoidance, and spirituality. The family members also utilized resources and support systems, such as their immediate families, mental health care professionals, and their churches.

    2016-01-01

    Emotions are inherent to team life, yet it is unclear how observers use team members' emotional expressions to make sense of team processes. Drawing on Emotions as Social Information theory, we propose that observers use team members' emotional displays as a source of information to predict the team's trajectory. We argue and show that displays of sadness elicit more pessimistic inferences regarding team dynamics (e.g., trust, satisfaction, team effectiveness, conflict) compared to displays of happiness. Moreover, we find that this effect is strengthened when the future interaction between the team members is more ambiguous (i.e., under ethnic dissimilarity; Study 1) and when emotional displays can be clearly linked to the team members' collective experience (Study 2). These studies shed light on when and how people use others' emotional expressions to form impressions of teams.

    Stolldorf, Deonni P

    2016-03-01

    : The perceived benefits of rapid response teams (RRTs) influence whether RRTs are used and sustained. Perceived benefits are particularly important to sustaining RRTs when limited RRT data are shared with organizational members. Nurse leaders' perceptions of the benefits of RRTs likely influence their support, which is crucial for sustained RRT use. The perceptions of RRT members and end users similarly will affect use. But little is known regarding the perceptions of nurse leaders, RRT members, and RRT users in this regard.This study sought to explore and compare the perceptions of nurse leaders, RRT members, and RRT users regarding the benefits of RRTs.A qualitative, multiple-case study design was used. Semistructured interviews were conducted with nurse leaders, RRT members, and RRT users at four community hospitals, as part of a larger mixed-methods study examining RRT sustainability. Purposive and snowball sampling were used. Recruitment strategies included e-mail and listserv announcements, on-site presentations, direct personal contact, and a study flyer.All participants reported perceiving various ways that RRTs benefit the organization, staff members, and patients. Variations in the benefits perceived were observed between the three participant groups. Nurse leaders' perceptions tended to focus on macro-level benefits. RRT members emphasized the teaching and learning opportunities that RRTs offer. RRT users focused on the psychological support that RRTs can provide.Both similarities and differences were found between nurse leaders, RRT members, and RRT users regarding their perceptions of RRT benefits. Differences may be indicative of organizations' information-sharing processes; of variation in the priorities of nurse leaders, RRT members, and RRT users; and of the challenges nurses face daily in their work environments. Future research should investigate whether the perceived benefits of RRTs are borne out in actuality, as well as the relationships

    Waelkens and Rufener's (1983) photoelectric lightcurve (as yet unexplored) of the newly discovered eclipsing binary HR 7464 has been analyzed. The photometric solution presented here reveals that this binary is an A5m + G main sequence detached system, which is particularly remarkable for the great dissimilarity between its members. The frequency of detached eclipsing pairs with very unequal members (i.e., with low mass ratio) is then discussed; some bimodality in the innate mass ratio distribution of close binaries is inferred.

    2014-01-01

    The aim of this study was to measure the publication rate of editorial board members in their board journals and to evaluate associated variables. We evaluated the ten highest-ranked journals according to the 5-year impact factor under 'Dentistry, Oral Surgery & Medicine' subject category for 2010, 2011, and 2012. All original research papers with at least one member of the editorial board as author were counted. Final analyses assessed associated variables such as size of the editorial board, number of papers published each year, and each journal's impact factor. Overall, there was an increase in the average number of articles published from 2010 (115.2 ± 52.2) to 2012 (134.7 ± 47.4). The number and percentage of articles published with editorial board members as authors over the three years did not follow the same pattern, with a slight decrease from 2010 to 2011 and an increase in 2012. The number of articles with editorial board members as authors was significantly higher for journals with impact factors ≥4.0. Journals with a higher impact factor and larger editorial board were associated with higher chances of editorial board members publishing in their respective journals. Participation of editorial board members as authors in publishing varies significantly among journals.

METHODS: A total of 153 patients with type 2 diabetes were assessed at a diabetes outpatient clinic and postal questionnaires were sent to nominated family members. The measures examined were diabetes knowledge, social support, well-being, and illness perceptions. RESULTS: When compared with those with diabetes, family members reported lower positive well-being and lower levels of satisfaction with support. They also perceived diabetes as a more cyclical illness, which was controlled more by treatment than by the individual. Family members also reported that the person with diabetes was more emotionally distressed and knew more about diabetes than the patient had actually reported himself or herself. There were no differences between the family members of those in good or poor glycaemic control. CONCLUSIONS: This study reinforces the importance of understanding social context and illness beliefs in diabetes management. It also highlights the potential for including family members in discussions and education about diabetes management.

    Full Text Available The aim of this study was to measure the publication rate of editorial board members in their board journals and to evaluate associated variables. We evaluated the ten highest-ranked journals according to the 5-year impact factor under ‘Dentistry, Oral Surgery & Medicine’ subject category for 2010, 2011, and 2012. All original research papers with at least one member of the editorial board as author were counted. Final analyses assessed associated variables such as size of the editorial board, number of papers published each year, and each journal’s impact factor. Overall, there was an increase in the average number of articles published from 2010 (115.2 ± 52.2 to 2012 (134.7 ± 47.4. The number and percentage of articles published with editorial board members as authors over the three years did not follow the same pattern, with a slight decrease from 2010 to 2011 and an increase in 2012. The number of articles with editorial board members as authors was significantly higher for journals with impact factors ≥4.0. Journals with a higher impact factor and larger editorial board were associated with higher chances of editorial board members publishing in their respective journals. Participation of editorial board members as authors in publishing varies significantly among journals.

    Full Text Available Corrosion is one of the major problems affecting the durability of reinforced concrete (RC structures. This paper investigates the effect of rebar corrosion on the performance of reinforced self-consolidating concrete (SCC members and the effectiveness of repair. A control RC member, which has no corrosion problem, was prepared to compare against corroded and repaired members. A number of reinforced concrete members having up to 50% corrosion level were constructed and tested to study the effect of corrosion on the structural performance of RC members. The beams with corrosion problem were repaired using carbon fiber reinforced polymer (CFRP sheets and U-wraps. All of the beams constructed, which are either not repaired or repaired, in this study were tested under two static line loads until failure. The effect of corrosion and effectiveness of repairing technique were assessed by evaluating the performance in terms of load carrying capacity, deflection, and ductility. Test results revealed that as the corrosion level increases, the loss in load carrying capacity increases. Repairing using CFRP improved the performance of corroded members. For example, when 50% corrosion level was achieved, the beam lost approximately 57% of its load carrying capacity, but when it was repaired, it recovered about 42% of its load carrying capacity.

    Full Text Available Nowadays, there is an agreement among organizations that reinforcing of education leads to the improvement of organizational performance. The emphasis on the human capital in organizations reflects the view that market values depend less on tangible resources, but more on intangible ones, particularly human resources. The main purpose of this study was to design a model for faculty members in public Agricultural Higher Education in Iran. A survey method was used to collect data from nine Public Agricultural Faculties in Iran. Samples were collected from faculty members using a simple random sampling method (n=284 and a questionnaire was used as the main research instrument to collect data. Reliability and validity were calculated using Structural Equation Modeling through LISREL software, version 8.54 (above 0.7. Finally, a model was developed and tested for faculty members in Agricultural Higher Education System in Iran. The findings showed that contextual variables (i.e. personal, organizational, social, educational, and professional development had direct impacts on the process of Human Resource Development (HRD. Furthermore, personal and organizational development had direct and indirect impacts on HRD (R2 = 0.70.

    We study a target sample of 68 low-mass objects (with spectral types in the range M4.5-L1) previously selected via photometric and astrometric criteria, as possible members of five young moving groups: the Local Association (Pleiades moving group, age=20 - 150 Myr), the Ursa Mayor group (Sirius supercluster, age=300 Myr), the Hyades supercluster (age=600 Myr), IC 2391 supercluster (age=35 - 55 Myr) and the Castor moving group (age=200 Myr). In this paper we assess their membership by using different kinematic and spectroscopic criteria. We use high resolution echelle spectroscopic observations of the sample to measure accurate radial velocities (RVs). Distances are calculated and compared to those of the moving group from the literature, we also calculate the kinematic Galactic components (U,V,W) of the candidate members and apply kinematic criterion of membership to each group. In addition we measure rotational velocities (v sin i) to place further constraints on membership of kinematic members. We find that...

    Commercial medical waste treatment technologies include incineration, melting, autoclaving, and chemical disinfection. Incineration disinfects, destroys the original nature of medical waste, and reduces the waste volume by converting organic waste content to carbon dioxide and water, leaving only residual inorganic ash. However, medical waste incinerator numbers have plummeted from almost 2,400 in 1995 to 115 in 2003 and to about 62 in 2005, due to negative public perception and escalating compliance costs associated with increasingly strict regulations. High-temperature electric melters have been designed and marketed as incinerator alternatives, but they are also costly and generally must comply with the same incinerator emissions regulations and permitting requirements. Autoclave processes disinfect medical waste at much lower operating temperatures than incinerators operate at, but are sometimes subject to limitations such as waste segregration requirements to be effective. Med-Shred, Inc. has developed a patented mobile shredding and chemical disinfecting process for on-site medical waste treatment. Medical waste is treated on-site at customer facilities by shredding and disinfecting the waste. The treated waste can then be transported in compliance with Health Insurance Portability and Accountability Act of 1996 (HIPAA) requirements to a landfill for disposal as solid municipal waste. A team of Idaho National Laboratory engineers evaluated the treatment process design. The process effectiveness has been demonstrated in mycobacterium tests performed by Analytical Services Incorporated. A process description and the technical and performance evaluation results are presented in the paper. A treatment demonstration and microbiological disinfecting tests show that the processor functions as it was intended.

    In order to account for wide variation in the relationship between leader-member exchange and employees' affective organizational commitment, we propose a concept termed supervisor's organizational embodiment (SOE), which involves the extent to which employees identify their supervisor with the organization. With samples of 251 social service employees in the United States (Study 1) and 346 employees in multiple Portuguese organizations (Study 2), we found that as SOE increased, the association between leader-member exchange and affective organizational commitment became greater. This interaction carried through to in-role and extra-role performance. With regard to antecedents, we found in Study 1 that supervisor's self-reported identification with the organization increased supervisor's expression of positive statements about the organization, which in turn increased subordinates' SOE.

    The acceptance and inclusion of persons with intellectual disability can vary across cultures, and understanding attitudes can provide insight into such variation. To our knowledge, no previous study has explored attitudes toward people with intellectual disability among Pakistani community members and disability service providers. We administered the Community Living Attitudes Scale (Henry et al., 1996), a measure of attitudes toward people with intellectual disability developed in the United States, to 262 community members and 190 disability service providers in Pakistan. Confirmatory factor analysis found a 4-factor solution (empowerment, similarity, exclusion, and sheltering) fit the Pakistani sample. More positive attitudes were observed in staff serving people with intellectual disability, females, Christians, Hindus, Sunnis, and people with greater education. We discuss implications for research, theory, and practice.

    Research has established robust links between gang membership, delinquency, violence and victimization. Yet studies examining the process of gang desistance in general and that of core gang members in particular, are quite rare. The current study aims to identify factors associated with desistance of core gang members as well as describe the nature of the process that these "formers" have undergone. Thirty-nine core ex-gang members (80% males and 20% females) from the San Francisco Bay area and Los Angeles, with an average length of 11.6-years gang membership, were interviewed regarding their involvement in the gang and the desistance process. A systematic qualitative analysis based on grounded theory methodology was mainly utilized. We found that the decision to leave the gang is a result of a combination of push (e.g., personal and vicarious victimization, burnout of gang lifestyle, disillusionment by the gang) and pull (e.g., parenthood, family responsibilities, religious and cultural awakening) factors that evolved over time. Push factors were more dominant in this domain. We also found that while male core ex-gang members tended to leave the gang more frequently because of push factors, female ex-gang members were more inclined to desist due to pull factors. Our analysis also showed that core gang members shared a general pattern of the desistance process comprising of the following 5 stages: triggering, contemplation, exploration, exiting and maintenance. Based on these results, we outlined stage-specific recommendations for agents of societal change to help in facilitating the desistance of core gang members.

    Full Text Available ABSTRACT The study examined the effect of membership of cooperative societies on the economic activities of farmers as well as the determinants of their income in rural Nigeria focusing on Anambra State. Data from 2506 members selected through multi-stage stratified random sampling were analyzed. The study found among others that members incomes are dependent upon their socio-economic profile such as age marital status and membership or otherwise of cooperative societies education cooperative marketing credit gender and business expertise. Also respondents depend largely on farming related activities for generation of income in the study area. Furthermore it was found that the major challenge of the farmer-members is inadequate fund poor education and illiteracy among most members conflict among members and lack of access to farm input. The Nigerian government is advised to formulate policies that will incorporate information from the local level that can support planning implementation and evaluation of programmes that can enhance farmers income this however will influence the pattern of agricultural growth in ways that can change income level of rural farmers to grow fast. The study recommends that cooperatives should intensify their education of members to gain more benefits and that government non-governmental organizations and international development agencies should show interest in supervising and providing development support to Farmers Cooperative Societies in rural Nigeria.

  15. Workplace Violence and Perceptions of Safety Among Emergency Department Staff Members: Experiences, Expectations, Tolerance, Reporting, and Recommendations.

    Copeland, Darcy; Henry, Melissa

    Workplace violence (WPV) is a widely recognized problem in emergency departments (EDs). The majority of WPV studies do not include nonclinical staff and do not address expectations of violence, tolerance to violence, or perceptions of safety. Among a multidisciplinary sample of ED staff members, specific study aims were to (a) describe exposure to WPV; (b) describe perceptions of safety, tolerance to violence, and expectation of violence; (c) describe reporting behaviors and perceived barriers to reporting violence; (d) examine relationships between demographic variables, experiences of violence, tolerance to violence, perceptions of safety, and reporting behaviors; and (e) identify perceptions of viable interventions to improve workplace safety. A cross-sectional design was used to survey ED staff members in a Level 1 Shock Trauma center. Eleven disciplines were represented in 147 completed surveys; 88% of respondents reported exposure to WPV in the previous 6 months. Members of every discipline reported exposure to WPV; 98% of the sample felt safe at work and 64% felt violence was an expected part of the job. Most violence was not reported, primarily because "nobody was hurt." Emergency department staff members expected and experienced violence; nevertheless, there was a widespread perception of safety. Perceptions of safety and reasons for not reporting did not mirror previous findings. The WPV exposure is not isolated to clinical staff members and occurs even when prevention strategies are in place. The definition of WPV and the individual's interpretation of the event might preclude reporting.

    Full Text Available The theoretical analysis of many problems in physics, astronomy, and applied mathematics requires an efficient numerical exploration of multimodal parameter spaces that exhibit broken ergodicity. Monte Carlo methods are widely used to deal with these classes of problems, but such simulations suffer from a ubiquitous sampling problem: The probability of sampling a particular state is proportional to its entropic weight. Devising an algorithm capable of sampling efficiently the full phase space is a long-standing problem. Here, we report a new hybrid method for the exploration of multimodal parameter spaces exhibiting broken ergodicity. Superposition enhanced nested sampling combines the strengths of global optimization with the unbiased or athermal sampling of nested sampling, greatly enhancing its efficiency with no additional parameters. We report extensive tests of this new approach for atomic clusters that are known to have energy landscapes for which conventional sampling schemes suffer from broken ergodicity. We also introduce a novel parallelization algorithm for nested sampling.

    Sugimori, S

    1993-04-01

    This study tested the hypothesis that undesirable members are salient in a small group, while desirable members become salient in a larger group. One hundred and forty-five students were randomly assigned to twelve conditions, and read sentences desirably, undesirably, or neutrally describing each member of a college student club. The twelve clubs had one of three group sizes: 13, 39, or 52, and the proportion of the desirable or undesirable to the neutral was either 11:2 or 2:11, forming a three-way (3 x 2 x 2) factorial. Twelve subjects each were asked to make proportion judgments and impression ratings. Results indicated that proportion of the undesirable members was over estimated when the group size was 13, showing negativity bias, whereas proportion of the desirable was overestimated when the size was 52, displaying positivity bias. The size 39 showed neither positivity nor negativity bias. These results along with those from impression ratings suggested that salience of member desirability interacted with group size. It is argued that illusory correlation and group cognition studies may well take these effects into consideration.

    Bondage-discipline/Dominance-submission/sadomasochism (BDSM) is an often misunderstood and misrepresented social phenomenon warranting further discourse and study. Community-based research that engages member perspective can assist in understanding socially marginalized experiences. The current study examined the role, meaning, and function of BDSM communities from the perspective of self-identified members. Seven nominal group technique workshops were conducted representing a variety of practitioner experiences and identities. Workshops involved 48 participants and resulted in the generation of 133 unique terms describing the role of BDSM communities in their lives. Terms were coded using a five-step procedure involving both academic and community members. A total of 15 categories were identified and included domains such as acceptance, sexual expression, friendship, safety, and sharing of educational knowledge. Results underscore the multifaceted nature of the role of such communities. While results consisted of mostly positive features, participants also identified certain negative aspects, such as conflict among members. Results from the study provide a succinct, member-derived, structured inventory of the role of BDSM communities that can serve to validate and synthesize existing research, improve dissemination of community voice around BDSM, and inform future research. We conclude with a discussion of the study's implications for sex education, clinical practice, and community dissemination.

    This report documents the findings of a survey of patients who received radioactive iodine therapy and their family members. The main objective of the survey was to gain an understanding of the experience of receiving radioactive iodine from the patient and family's perspective. The data from this study helped to inform the ARCP and GMA as they developed AC-9 - Principles of the management of radionuclide therapies. A survey was distributed to 700 patients and family members through physicians at 8 sites across Canada. Locations included: Newfoundland, Nova Scotia, Ontario (2 sites), Quebec (2 sites), Manitoba and British Columbia. A total of 190 patients and 140 family members returned completed surveys. Data was analyzed separately for individuals treated as inpatients and those treated as outpatients. The results of the survey provided a perspective from patients and families about their experiences regarding radioactive iodine therapy. The data indicate variation in patients' and family members' perspectives about how precautions are to be implemented. Both patients and family members expressed the desire for more information regarding many aspects of the treatment experience. The results have implications for the development of patient information, continuing education (in particular in the areas of precaution), the provision of access to supportive and counselling services, and the importance of looking at the individual situations of patients and their families.

    the power dynamics of relationships/interactions between faculty members and students are of crucial importance for positive student outcomes. This study aimed to investigate the relationship between the perceptions and expectations of midwifery students in relation to the use of power by faculty members and bases of power. descriptive, quantitative study. a school for health sciences in Turkey. 122 midwifery students at the school. data were collected using a perceived leadership power survey, and analysed by frequency distribution, arithmetic mean, variance analysis and Cronbach's alpha. the students perceived that faculty members used coercive power most often and used reward power least often. Students expected their instructors to use expert power. In addition, in the examination of relationships between power bases, it was determined that there were positive correlations between legitimate, referent, reward and expert power, but coercive power was only positively correlated with legitimate power. this study found that students expect faculty members to use expert power, and faculty members need to reconsider their power bases. The factors affecting the perceptions of midwifery students regarding the use of power should be analysed in more detail. Copyright 2008 Elsevier Ltd. All rights reserved.

    Despite advocacy by professional nursing organizations, no randomized controlled trials (RCTs) have evaluated the response of family members to a visit with an adult patient during a postanesthesia care unit (PACU) stay. Therefore, the purpose of this RCT was to evaluate the impact of a brief PACU visitation on the anxiety of family members. The study was conducted in a phase I PACU of a large community-based hospital. Subjects were designated adult family members or significant others of an adult PACU patient who had undergone general anesthesia. A pretest-posttest RCT design was used. The dependent variable was the change in anxiety scores of the visitor after seeing his or her family member in the PACU. Student t test (unpaired, two tailed) was used to determine if changes in anxiety scores (posttest score-pretest score) were different for the PACU visit and no visit groups. A total of 45 participants were studied over a 3-month period, with N=24 randomly assigned to a PACU visit and N=21 assigned to usual care (no PACU visit). Participants in the PACU visit group had a statistically significant (P=.0001) decrease in anxiety after the visitation period (-4.11±6.4); participants in the usual care group (no PACU visit) had an increase in anxiety (+4.47±6.6). The results from this study support the value and importance of PACU visitation for family members.

    Thirty-three families (71 subjects) were screened for the presence of Candida albicans in mouthwash or stool specimens; 12 families (28 subjects) were culture-positive for this yeast. An enrichment procedure provided a twofold increase in the recovery of C. albicans from mouthwash specimens. Nine of the twelve culture-positive families had two positive members each, two families had three positive members each, and one family had four positive members. Genetic profiles were obtained by three methods: pulsed-field gel electrophoresis; restriction endonuclease analysis, and random amplification of polymorphic DNA analysis. DNA fingerprinting of C. albicans isolated from one body site three consecutive times revealed that each of the 12 families carried a distinct genotype. No two families shared the same strain, and two or more members of a family commonly shared the same strain. Intrafamily genotypic identity (i.e., each member within the family harbored the same strain) was demonstrated in six families. Genotypes of isolates from husband and wife differed from one another in five families. All three methods were satisfactory in determining genotypes; however, we concluded that restriction endonuclease analysis provided adequate resolving power.

  9. Preserving performance of concrete members under seismic loading conditions

    Dry, Carolyn M.; Unzicker, Jacob

    1998-06-01

    Normal reinforced concrete lacks the ability to directly respond to the formation of cracking within its own cross section during dynamic loading. A way to introduce this ability is to apply self-healing concepts in the design of reinforced concrete members. Such members could then 'intelligently' react in the event of damaging forces -- by deriving the means of repair from within themselves. Self- healing involves the timed release of adhesive into the member at the time of cracking. Chemically inert encapsulations are filled with adhesive and cast within the cross section of the member. At the onset of cracking, the wall fractures, allowing adhesive to exit and penetrate the developing crack. With this method, adhesives with different characteristics could be applied to different areas of a monolithic, reinforced concrete structural system, in order to accomplish specific results. For example, high strength adhesive could be used in areas where increased stiffness was desired, and more flexible adhesive could be potentially be used to improve energy dissipation or damping. The method would be most appropriate for highly indeterminate structures, where moment redistribution between members tends to 'refocus' stress temporarily. This gives the adhesive time to repair the cracked section and improve local capacity against further damage.

    Adherence to positive airway pressure (PAP) therapy for obstructive sleep apnea (OSA) remains a challenge in children. We hypothesized that the presence of another family member on PAP therapy (parent, sibling, other family member) would be associated with better adherence in the child. We conducted a retrospective chart review to identify children family member on PAP therapy, patient demographics, and clinical characteristics. Group differences between children with and without a family member on PAP therapy were determined using χ(2) test and Wilcoxon two-sample test. PAP adherence measures at each time point and patterns of change across time between the two groups were examined using mixed-effects models. The final analytic sample included 56 children: age 13.2 ± 3.7 years, 60% male, 67% African American, 65% obese, and 32% with developmental disabilities. The mean obstructive apnea-hypopnea index was 25.2 ± 28.7, and 19 (33%) had a family member on PAP therapy. Overall PAP adherence was 2.8 ± 2.4 h/night at 3 months. At month 3, the group with a family member on PAP therapy had significantly greater average nightly PAP use on all nights (3.6 ± 0.6 vs. 2.3 ± 0.39) and on nights used (4.8 ± 0.6 vs. 3.8 ± 0.40); (p value = 0.04). Overall PAP adherence was low, but having a family member on PAP therapy as a "role model" was associated with better adherence.

    Full Text Available The group members shall draw up a theory of the genesis of mental suffering, which is part of the group’s culture. This is an implicit theory. It has not been disseminated, organized and systematized. However, the group members make use of it. Its recognition is an important point of reference for the analyst. An analyst who is able to recognize its features and content will understand better how the group is progressing in its attempt to achieve health. The recognition of this theory also helps the analyst understand what image the group members have of themselves as a group.Keywords: Psychopathology, Psychoanalysis, Group psychotherapy, Psychological Field Theory, Group self-representation

    In this paper, we defined a new secure multi-party computation problem, called Oblivious Set-member Decision problem, which allows one party to decide whether a secret of another party belongs to his private set in an oblivious manner. There are lots of important applications of Oblivious Set-member Decision problem in fields of the multi-party collaborative computation of protecting the privacy of the users, such as private set intersection and union, anonymous authentication, electronic voting and electronic auction. Furthermore, we presented two quantum protocols to solve the Oblivious Set-member Decision problem. Protocol I takes advantage of powerful quantum oracle operations so that it needs lower costs in both communication and computation complexity; while Protocol II takes photons as quantum resources and only performs simple single-particle projective measurements, thus it is more feasible with the present technology.

    1. Definitions a) CERN Staff Rules and Regulations Article S IV 1.02 of the Staff Rules defines a "partner", irrespective of gender, as "any person linked to an employed member of the personnel by a partnership officially registered in a Member State". Partners are regarded as family members for the purposes of protection against the financial consequences of illness and accidents. b) Swiss Federal Law Under Swiss federal law, to which the text below essentially refers, the following definitions apply: "partners": a couple of the same sex (linked by a registered partnership), "common-law spouses": a couple of the opposite sex (unmarried). Provided that they are aged 18 or more and are not blood relatives, two people of the same sex ("partners") may officially register their partnership with the competent registry office in order to give it a legal framework (a civil partnership commonly known as the Federal PACS...

  16. Exotensioned structural members with energy-absorbing effects

    Structural members having enhanced load bearing capacity per unit mass include a skeleton structure formed from strips of material. Notches may be placed on the strips and a weave of tensile material placed in the notches and woven around the skeleton structure. At least one pair of structural members can be jointed together to provide very strong joints due to a weave patterns of tensile material, such as Kevlar, that distributes stress throughout the structure, preventing stress from concentrating in one area. Methods of manufacturing such structural members include molding material into skeletons of desired cross section using a matrix of molding segments. Total catastrophic failures in composite materials are substantially avoided and the strength to weight ratio of structures can be increased.

    In August 2009, the American Association of Colleges of Pharmacy (AACP) Council of Sections established a Task Force to assess the current status of compounding education at its member institutions and to provide recommendations for future direction. The Task Force conducted a survey in late June 2010 of faculty members enrolled in the AACP Pharmaceutics and Pharmacy Practice sections to gain qualitative information of the current state of compounding education. The survey results were then organized around eight curricular topics for which the Task Force members provided interpretations and recommendations. A final report was sent to the AACP Council of Sections on February 15, 2011. This publication provides the information contained in that final report to the professional community.
