The aim of this study was to clarify the relationship between maceration and wound healing. A prospective longitudinal design was used in this study. The wound condition determined the type of dressings used and the dressing change frequency. A total of 62 participants with diabetic foot ulcers (70 wounds) were divided into two groups: non-macerated (n = 52) and macerated wounds (n = 18). Each group was evaluated weekly using the Bates-Jensen Wound Assessment Tool, with follow-ups until week 4. The Mann-Whitney U test showed that the changes in the wound area in week 1 were faster in the non-macerated group than the macerated group (P = 0·02). The Pearson correlation analysis showed a moderate correlation between maceration and wound healing from enrolment until week 4 (P = 0·002). After week 4, the Kaplan-Meier analysis showed that the non-macerated wounds healed significantly faster than the macerated wounds (log-rank test = 19·378, P = 0·000). The Cox regression analysis confirmed that maceration was a significant and independent predictor of wound healing in this study (adjusted hazard ratio, 0·324; 95% CI, 0·131-0·799; P = 0·014). The results of this study demonstrated that there is a relationship between maceration and wound healing. Changes in the wound area can help predict the healing of wounds with maceration in clinical settings. © 2016 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

Full Text Available The flavoring of vinegars with aromatic fruits and medicinal herbs is a practice with increasing trend mostly in countries with oenological tradition, resulting in a product of improved quality and consumer attractiveness. This study was directed towards the evaluation of the impact of the maceration process on the volatile signature of wine-based aromatic vinegars (WBAVs. The evaluation was performed using solid phase microextraction (SPME combined with gas chromatography combined with mass spectrometry (GC-MS. Experimental parameters influencing headspace solid (HS-SPME extraction efficiency, were optimized using an univariate experimental design. The best results were achieved using a polydimethylsiloxane (PDMS fiber, 10 mL of vinegar sample, at 50 °C for 30 min of extraction. This way One hundred and three volatile organic compounds (VOCs, belonging to different chemical families including ethyl esters (37, higher alcohols (20, fatty acids (10, terpenoids (23, carbonyl compounds (six, lactones (five and volatile phenols (two, were identified in wine vinegar (control and WBAV. As far as we know, 34 of these VOCs are reported for the first time in macerated vinegars. Higher alcohols and lactones are the major chemical families in WBAV macerated with apple, whereas terpenoids are predominant in WBAV macerated with banana. The obtained data represent a suitable tool to guarantee the authenticity and genuineness of WBAV, as well as to promote the production of WBAV with improved sensorial and organoleptic properties. To the best of our knowledge, there are no reported studies dealing with the volatile signature of WBAV enriched with banana, passion fruit, apple and pennyroyal.

Macerals in coal are of different types: reactive and inert. These macerals are differ in their physical and chemical properties. Column flotation method has been used to separate the reactive macerals in a non-coking coal. The enriched coal is then characterized in order to understand the changes in the coking potential by different techniques. It is then used in making of metallurgical coke by proper blending with other coals. Enriched coal enhance the properties of metallurgical coke. This shows a path of utilization of non-coking coal in metallurgical coke making.

Specific macerals in coals and distinct solid organic bitumens within limestones from northern China were separately analysed in situ by laser micropyrolysis gas chromatography-mass spectrometry. The major pyrolysates from the resinite and cutinite macerals included aromatic hydrocarbons such as alkylnaphthalenes, alkylbenzenes, alkyltetralins (in the resinite) and alkylphenols (in the cutinite), and aliphatic hydrocarbons such as n-alk-1-enes, n-alkanes, pristane and phytane. The same classes of hydrocarbons were also detected in co-occurring vitrinites, including very similar relative distributions of alkylnaphthalenes in the case of the resin-rich coal. Several observed quantitative differences are consistent with previous molecular data from maceral concentrates. The qualitative similarity of the maceral data suggest (1) extensive assimilation of free hydrocarbons by all macerals within the coals; or (2) inefficient targeting of the macerals by the laser, although microscopic observation showed that the laser craters were generally constrained within surface boundaries of the maceral. The organic composition of a solid bitumen within a Carboniferous limestone was characterised by a distinctive distribution of C{sub 0}-C{sub 4} alkyldibenzofurans, as well as alkylbenzenes, alkylnaphthalenes and a low molecular weight distribution of n-alk-1-enes and n-alkanes. These data suggest the solid bitumen comprises a strongly aromatic matrix with terrestrially-derived oxygen functionality and alkyl linkages. The same aromatic and aliphatic hydrocarbon products were also detected in the morphologically homogenous carbonates hosting the solid bitumens, indicating the presence of sub-microscopic organic moieties throughout the limestone.

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.

Full Text Available Rosemary (Rosmarinus officinalis, garden sage (Salvia officinalis, summer savory (Satureja hortensis, laurel (Laurus nobilis, and other aromatic plants were put in olive oil and exposed to ultrasounds for different duration. Filtrated oils were dissolved in cyclohexane, and UV-Vis measurements were carried out. Absorbance values corresponding to chlorophylls, carotenoids, flavonoids (370 nm, and polyphenols (around 300 nm were measured. In addition, for some samples, total phenols were determined using Folin-Denis reagent and compared with the similar maceration procedure in water solvent (instead of olive oil. Maceration without ultrasound in olive oil for each plant was also compared with ultrasound-assisted extraction. The results show that significant amount of aromatic content can be extracted in olive oil by applying ultrasounds for only few minutes, especially for Salvia officinalis powder. The use of UV-Vis measurements is simple but enough to examine the extent of phenol content extraction through such maceration procedure.

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 CH{sub 2}/CH{sub 3} 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.

Full Text Available In recent decades, the subject of gas emission in underground coal mines in many countries is an important subject. Many factors affect in gas emissions in coal seams. Geological and physical structures of coal are affecting on gas emissions'. Also, composition and mineralization of coal, affect in coal permeability for different gases. In this study, the relationship between maceral composition and coal permeability in Tazareh and Parvadeh mines has been studied. Accordingly, a laboratory studies to investigate the relationship between coal composition and coal permeability was done. In coal samples, with MFORR equipment the permeability test was done. With microscopic analysis, the maceral contents of coal such as Inertinite and Vitrinite have been measured. Accordingly, many coal samples of Parvadeh and Tazareh coal mines have the pyrite as the dominant mineral matter. Parvadeh coal samples has the average percentage of Vitrinite equal 81.34% and 10.52% Inertinite. Also, in the Tazareh coal samples in Eastern Alborz coal mines, the average percentage of Vitrinite is 69.31% and inertinite is 22.47%. The average percentage of Pyrite content in Parvadeh coal samples in Tabas coal mines is 2.38% and in the Tazareh coal samples in Eastern Alborz coal mines is 2.62%.  The permeability test results have been shown, which, with increase of Inertinite contents, the permeability of coal is increasing. Also, test results have been shown, there was a reduction in the coal permeability with increasing of mineral contents and carbonate contents of the coal. So, the coal permeability in Tabas coal samples is more than Eastern Alborz coal samples.

Automatic analysis of macerals and reflectance; Analisis Automatico de Macerales y Reflectancia

Catalina, J.C.; Alarcon, D.; Gonzalez Prado, J.

1998-12-01

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)

A new method using the small porcelain as the reactor combined with increasing the flow rate of carrier gas was proposed, which has the advantage of excluding the condensation of volatile produced by heated solid samples on the windows during in situ diffuse reflectance FTIR experiment. Moreover, the feasibility of this method was also discussed. Using this method, the distribution and thermal stability of hydrogen bonds in coal macerals obtained from two coals were studied. The results show that the differences between the distribution of hydrogen bonds formed by hydroxyl group in the macerals of two coals were very similar. For the vitrinites the thermal stability of SH-N, carboxylic acid dimmers and self-associated OH is higher than those in inertinites but for OH-N and hydroxyl tetramers and OH-OR{sub 2} there are no obvious laws. For OH-{pi}, its content increased with increasing temperature to 350-380{sup o}C, and then decreased with further heating. The variation of hydrogen bonds in macerals reflects the difference in their structure.

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.

The influence of micro-oxygenation (MOX) and maceration with oak chips treatments on wine was studied on wine samples from three vintages produced in the Yarra Valley, Australia. A full factorial design was employed where two factors (MOX and oak chips treatments) had two levels and one factor (vintage) had three levels. Three replicated treatments were run for each factor's setting. Wine samples were analysed using conventional laboratory methods with respect to the phenolic wine compounds and colour attributes since the phenolic fraction of wine is most affected by both MOX and oak maceration treatments. The same wine samples were measured with an electronic tongue based on potentiometric chemical sensors. The significance of treatments and vintage effects on wine phenolic compounds was assessed using ANOVA and ANOVA-Simultaneous Component Analysis (ASCA). Cross-validation was used for the ASCA sub-model optimisations and permutation test for evaluations of the significance of the factors. Main effects of vintage and maceration with oak chips were found to be significant for both physicochemical and the ET data. Main effect of MOX treatment was also found significant for the physicochemical parameters. The largest effect on the phenolic composition of wine was due to its vintage, which accounted for 70% and 33% of total variance in the physicochemical and ET data respectively. The ET was calibrated with respect to the total phenolic content, colour density and hue and chemical ages 1 and 2 and could predict these parameters of wine with good precision.

Maceration and fermentation time and temperatures are important factors affecting wine quality. In this study different maceration times (3 and 6 days) and temperatures (15  and 25 ) during production of red wine (Vitis vinifera L. Cabernet Sauvignon) were investigated. In all wines standard wine chemical parameters and some specific parameters as total phenols, tartaric esters, total flavonols and colour parameters (CD, CI, T, dA%, %Y, %R, %B, CIELAB values) were determined. Sensory evaluation was performed by descriptive sensory analysis. The results demonstrated not only the importance of skin contact time and temperature during maceration but also the effects of transition temperatures (different maceration and fermentation temperatures) on wine quality as a whole. The results of sensory descriptive analyses revealed that the temperature significantly affected the aroma and flavour attributes of wines. The highest scores for 'cassis', 'clove', 'fresh fruity' and 'rose' characters were obtained in wines produced at low temperature (15 ) of maceration (6 days) and fermentation.

We describe a special, interesting phenomenon found in the anterior horn of the lateral meniscus (AHLM): most tear patterns in the AHLM are distinctive, with loose fibers in injured region and circumferential fiber bundles were separated. We name it as macerated tear. The goal of this study was to bring forward a new type of meniscal tear in the AHLM and investigate its clinical value. AHLM tears underwent arthroscopic surgery from January 2012 to December 2014 were included. Data regarding the integrity of AHLM were prospectively recorded in a data registry. Tear morphology and treatment received were subsequently extracted by 2 independent reviewers from operative notes and arthroscopic surgical photos. A total of 60 AHLM tears in 60 patients (mean age 27.1 years) were grouped into horizontal tears (n = 15, 25%), vertical tears (n = 14, 23%), complex tears (n = 6, 10%), and macerated tears (n = 25, 42%). There were 6 patients with AHLM cysts in macerated tear group and one patient in vertical tear group. 60 patients were performed arthroscopic meniscus repairs and were followed-up with averaged 18.7 months. Each group had significant postoperative improvement in Lysholm and IKDC scores (p 0.05). This study demonstrated that the macerated tear is common in the tear pattern of AHLM. However, feasibility of the treatment of this type of meniscal tear, especially the meniscus repairs still requires further study.

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 (MBIC 50 active range of 0.004-0.016% v/v), exhibited moderate inhibition of quorum sensing (QSIC 50 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

Two different Metschnikowia strains (M. pulcherrima MP 346 or M. fructicola MF 98-3) were applied for the first time, during pre-fermentative cold maceration (PCM) in order to enhance the properties and stability of Sangiovese wine color. During the 2014 and 2015 vintages a total of eight wines were produced with 24 h of cold maceration (PCM 24 h) or 72 h (PCM 72 h), respectively. PCM was carried out in presence of MP 346 or MF 98-3 or pectic enzyme (Cuvée Rouge). The sequential inoculation of S. cerevisiae strain was carried out at the end of PCM. After 12 months in the bottle, the MP 346 and MF 98-3 wines contained much higher levels of total flavonoids than the Control sample for both vintages and regardless PCM duration. Moreover, in both vintages only MF 98-3 showed a higher color intensity than the Control sample after 12 months in the bottle. However, neither PCM duration nor the microbial/enzymatic treatment increased the level of anthocyanins at draining off. Both wines produced by the pre-fermentative inoculum with Metschnikowia strains (MP 346 and MF 98-3) retained their red hue, regardless the duration of pre-fermentative and fermentative macerations, while the Control wines were characterized by faster rates of color loss.

Measurement of reflectance of coal macerals: its automation and significance

Energy Technology Data Exchange (ETDEWEB)

Davis, A.

1978-06-01

A prime objective of the Pennsylvania State University's DOE program is the characterization of 1,300 samples of U.S. coals. Reflectance determination plays a major role in meeting this objective, because it is used as an accurate rank index both to select coals for testing and to investigate property-behavior interrelationships using the Penn State/DOE Coal Data Base. Reflectances of coal macerals are related to their refractive and absorptive indices by the Beer equation; the refractive index of the medium and the wavelength of light need to be specified. Determinations usually are made in immersion oil at 546 nm. Properties of vitrinite make it the most suitable maceral for these measurements, but the variety of vitrinite selected may depend upon the intended application. Vitrinite reflectance is considered to be dependent upon the degree of aromatization of its structural units. Although some of the earlier investigators believed that the reflectance of coals increased in a discontinuous, stepped manner as their rank increased, the bulk of assembled data suggests that the change is continuous. Some recent results indicate that there may be more than one coalification track for coals with different geological histories, resulting in displacement from the general trend. Several techniques have been employed to determine the optical properties of coal constituents. Usual comparative method involves the use of a microscope photometer to compare the intensity of light reflected by particles within a polished pellet of coal to that of a glass or synthetic mineral standard. Because coal is anisotropic it is common to measure either maximum reflectance in polarized light or random reflectance in non-polarized light. Various eqipment modifications and accessories have been used to improve the ease of measuring maximum reflectance.

The aim of this paper was to study how maturity and maceration length affect color, phenolic compounds, polysaccharides, and sensorial quality of Cabernet Sauvignon and Tempranillo wines at three stages of grape ripening. Ripeness increased color extractability, phenolic compounds, and polysaccharide concentrations. Moreover, the proanthocyanidin mean degree of polymerization (mDP) and the percentage of prodelphinidins also increased with maturity, whereas the percentage of galloylation decreased. In general, wines from riper grapes contain higher proportions of skin proanthocyanidins. Color and anthocyanin concentration decreased when the maceration was longer, whereas polysaccharide and proanthocyanidin concentrations did the opposite. It was also detected that the mDP and the percentage of prodelphinidins decreased when the maceration was extended, whereas the percentage of galloylation increased. These data seem to indicate that proanthocyanidin extraction from seeds is clearly increased throughout the maceration time.

To understand the relationship of the tar compositions and the coal macerals, the tars obtained from the pyrolysis and hydropyrolysis of Shenmu coal macerals in a fixed-bed reactor were analysed using GC-MS. And the effects of petrographic component, atmosphere and pressure on the yield of aromatic hydrocarbon, phenols, hydrocarbons, oxygen-containing heterocycle and PAHs were systematically investigated. The results show that there is great difference in the composition and the relative content of long chain hydrocarbons, aromatic hydrocarbons, phenols, oxygen-containing heterocycle and PAHs in tars from vitrinite and inertinite pyrolysis. Vitrinite tar contains high content of hydrocarbon with long chain, and inertinite tar contains high content of aromatic hydrocarbons, phenols, oxygen-containing heterocycle and PAHs. It suggests that vitrinite has lower aromaticity and longer chain in its structure than inertinite, which is in well agreement with the result from {sup 13}C NMR and FT-IR test. The tar yield of hydropyrolysis is higher than that of pyrolysis. With increasing the hydrogen pressure, the yield of tar increases greatly. The content of phenols and naphthalene in vitrinite tar form hydropyrolysis under 0.1 MPa is much lower than that form pyrolysis, while that of inertinite tar changes a little. The difference of tar compositions and relative content during pyrolysis and hydropyrolysis reflects the effect of hydrogenation and hydrocracking reactions and the structure characteristics of the macerals. 12 refs., 3 figs.

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.

Herbal liqueurs are alcoholic beverages produced by the maceration or distillation of aromatic and medicinal plants in alcohol, and are also highly valued for their medicinal properties. The process conditions, as well as the number and quantity of the plants employed, will have a great influence on the quality of the liqueur obtained. The aim of this research was to optimize these important variables. A Box-Benhken experimental design was used to evaluate the independent variables: alcohol content, amount of plant and time during the experimental maceration of plants in grape marc distillate. Four plants were assessed, with the main compound of each plant representing the dependent variable evaluated with respect to following the evolution of the maceration process. Bisabolol oxide A in Matricaria recutita L., linalool in Coriander sativum L. and eucalyptol in Eucalyptus globulus Labill. were quantified using a gas chromatography-flame ionization detector. Glycyrrhizic acid in Glycyrrhiza glabra L was determined using a high-performance liquid chromatography-diode array detector. Other dependent variables were also evaluated: total phenolic content, color parameters and consumer preference (i.e. appearance). The experimental designs allowed the selection of the optimal maceration conditions for each parameter, including the preference score of consumers: 70% (v/v) of ethanol, 40 g L -1 plant concentration and a maceration process of 3 weeks. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

Full Text Available This study deals with the determination of the content of both free and bound terpenes in berries and wine of the aromatic grapevine variety ‘Irsai Oliver’. Grapes were macerated in juice for different time intervals (viz. 0; 5; 12; 24 hours and thereafter processed to wine. The objective was to map the dependence of some selected terpenes on the period of maceration. Using gas chromatography, some nine organic compounds were detected. Attention was paid to contents of linalool (3,7-dimethylokta-1,6-dien-3-ol, 2,6-dimetyl-3,7-octadiene-2,6-diol, hotrienol ([(5E-3,7-dimethylocta-1,5,7-trien-3-yl] acetate, αterpineol (2-(4-Methyl-1-cyclohex-3-enylpropan-2-ol, β-citronellol (3,7-Dimethyloct-6-en-1-ol, nerol ((Z-3,7-dimethyl-2,6-octadien-1-ol, geraniol ((trans-3,7-dimethyl-2,6-oktadien-1-ol and epoxylinalool (2-(5-ethenyl-5-methyloxolan-2-ylpropan-2- ol: epoxylinalool 1 (trans-linalool oxide (furanoid cis-linalool oxide (furanoid and epoxylinalool 2 (trans-linalool oxide (pyranoid cis-linalool oxide (pyranoid. Some basic wine parameters (alcohol, pH, sugars and total acids were estimated as well. The terpene content in wine increased gradually with the period of maceration. The highest and the lowest amounts of terpenes were recorded after 24 hours of maceration and no maceration, respectively. The terpene glycosides content was higher than that of the aglycones. Linalool and 2,6-dimetyl-3,7-octadiene-2,6-diol were the most abundant terpenes.

Application of reflectance micro-Fourier Transform infrared analysis to the study of coal macerals: An example from the Late Jurassic to Early Cretaceous coals of the Mist Mountain Formation, British Columbia, Canada

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 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.

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 C 6 -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.

Macrinite is a, generally, rare inertinite maceral, often incorporating remnants and fragments of other macerals, including vitrinite, liptinite, and other inertinite. The associated inertinites include multiple forms of funginite. Funginite is also commonly found in association with vitrinite of slightly elevated reflectance and with degraded varieties of vitrinite. Together with the highly degraded macrinite, the latter two associations are here inferred to be part of a continuum of fungal and microbial degradation of peat. In any case, the origin of some macrinite is potentially distinct from that of inertinite generated by fire. (author)

2004-12-01

The hydropyrolysis characteristics of Shenmu coal and its macerals were investigated using TG-151 thermo balance, and the evolved gases were on-line analyzed by mass spectroscopy. The results show that vitrinite has higher volatile yield, maximum weight loss rate and lower peak temperature. Vitrinite produces more C{sub 1} - C{sub 4} lighter hydrocarbons and C{sub 5} - C{sub 8} aromatic hydrocarbons than inertinite. Vitrinite has a higher water yield, which is consistent with that the vitrinite has higher phenolic-OH content. The difference in the evolved gases and water between pyrolysis and hydropyrolysis shows the effect of hydrogenation and hydrocracking during hydropyolysis. 11 refs., 4 figs., 1 tab.

The impact of extended maceration (EM) was studied in Cabernet Sauvignon grapes sourced from a vineyard subjected to four regulated deficit irrigation (RDI) treatments: (I) 100% replenishment of crop evapotranspiration (100% ETc), (II) 70% ETc, (III) 25% ETc until véraison, followed by 100% ETc until harvest, and IV) 25% ETc. Each vineyard replicate was made into wine with two replicates designated as controls (10-day skin contact) and two as extended maceration (EM, 30-day skin contact). The mean degree of polymerization (mDP), size distribution, concentration, and composition of wine proanthocyanidins (PAs) and monomeric flavan-3-ols of 90 fractions were characterized by preparative and analytical HPLC techniques. The maceration length imparted a larger effect on most chemical parameters. The RDI treatment had no effect on the extraction patterns of anthocyanins, PAs, and/or on the origin of the PAs extracted into the wines. Conversely, EM led to anthocyanin losses and increased PA extraction during maceration, with ~73% of seed-derived PAs. Accordingly, the concentration of monomeric flavan-3-ols, oligomeric (2 ≤ mDP < 5) and polymeric PAs (mDP ≥ 5) was higher in EM wines. The size distribution of the wines' PAs revealed two major peaks as a function of concentration at mDP 2 (22-27% of total PAs mass) and at mDP 6-7 (12-17% of total PAs mass) and was found to follow a non-normal Rayleigh-type distribution.

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

Several genes encoding enzymes capable of degrading plant cell wall components have been cloned from Erwinia carotovora subsp. carotovora EC14. Plasmids containing cloned EC14 DNA mediate the production of endo-pectate lyases, exo-pectate lyase, endo-polygalacturonase, and cellulase(s). Escherichia coli strains containing one of these plasmids or combinations of two plasmids were tested for their ability to macerate potato tuber slices. Only one E. coli strain, containing two plasmids that encode endo-pectate lyases, exo-pectate lyase, and endo-polygalacturonase, caused limited maceration. The pectolytic proteins associated with one of these plasmids, pDR1, have been described previously (D. P. Roberts, P. M. Berman, C. Allen, V. K. Stromberg, G. H. Lacy, and M. S. Mount, Can. J. Plant Pathol. 8:17-27, 1986) and include two secreted endo-pectate lyases. The second plasmid, pDR30, contains a 2.1-kilobase EC14 DNA insert that mediates the production of an exo-pectate lyase and an endo-polygalacturonase. These enzymes are similar in physicochemical properties to those produced by EC14. Our results suggest that the concerted activities of endo-pectate lyases with endo-polygalacturonase or exo-pectate lyase or both cause maceration.

Full Text Available An investigation was carried out to extract polyphenols from the peel of kinnow (Citrus reticulate L. by maceration and ultrasound-assisted extraction (UAE techniques. The antioxidant potential of these polyphenols was evaluated using ferric reducing antioxidant power (FRAP, 2,2-diphenyl-1-picrylhydrazyl (DPPH, and superoxide radical scavenging assays; and their antimicrobial activity was assessed against bacterial strains Staphyloccoccus aureus, Bacillus cereus, and Salmonella typhimurium. The highest extraction yield was obtained through the solvent ethanol at 80% concentration level, whereas UAE was a more efficient technique and yielded comparatively higher polyphenol contents than maceration. Maximum polyphenols were extracted with 80% methanol [32.48 mg gallic acid equivalent (GAE/g extract] using UAE, whereas minimum phenolics (8.64 mg GAE/g extract were obtained with 80% ethyl acetate through the maceration technique. Elevated antioxidant activity of kinnow peel extracts was exhibited in three antioxidant assays, where 80% methanolic extracts showed the highest antioxidant activity (27.67±1.11mM/100 g for FRAP and the highest scavenging activity, 72.83±0.65% and 64.80±0.91% for DPPH and superoxide anion radical assays, respectively. Strong correlations between total polyphenols and antioxidant activity were recorded. Eleven phenolic compounds—including five phenolic acids and six flavonoids—were identified and quantified by high performance liquid chromatography. Ferulic acid and hesperidin were the most abundant compounds whereas caffeic acid was the least abundant phenolic compound in kinnow peel extracts. Maximum inhibition zone was recorded against S. aureus (16.00±0.58 mm whereas minimum inhibition zone was noted against S. typhimurium (9.00±1.16 mm. It was concluded that kinnow mandarin peels, being a potential source of phenolic compounds with antioxidant and antimicrobial properties, may be used as an ingredient for

In this paper we present potential usage of the 3D vision system for registering features of the macerated cranial bones. Applied 3D vision system collects height profiles of the object surface and from that data builds a three-dimensional image of the surface. This method appeared to be accurate enough to capture anatomical details of the macerated bones. With the aid of the 3D vision system we generated images of the surface of the human calvaria which was used for testing the system. Performed reconstruction visualized the imprints of the dural vascular system, cranial sutures, and the three-layer structure of the cranial bones observed in the cross-section. We figure out that the 3D vision system may deliver data which can enhance estimation of sex from the osteological material.

mRNA levels of members of the Vascular Endothelial Growth Factor family (VEGF-A, -B, -C, -D, Placental Growth Factor/PlGF) have been investigated as tissue-based markers of colon cancer. These studies, which used specimens obtained by surgical resection or colonoscopic biopsy, yielded contradictory results. We studied the effect of the sampling method on the marker accuracy of VEGF family members. Comparative RT-qPCR analysis was performed on healthy colon and colon carcinoma samples obtained by biopsy (n = 38) or resection (n = 39) to measure mRNA expression levels of individual VEGF family members. mRNA levels of genes encoding the eicosanoid enzymes cyclooxygenase 2 (COX2) and 5-lipoxygenase (5-LOX) and of genes encoding the hypoxia markers glucose transporter 1 (GLUT-1) and carbonic anhydrase IX (CAIX) were included as markers for cellular stress and hypoxia. Expression levels of COX2, 5-LOX, GLUT-1 and CAIX revealed the occurrence in healthy colon resection samples of hypoxic cellular stress and a concurrent increment of basal expression levels of VEGF family members. This increment abolished differential expression of VEGF-B and VEGF-C in matched carcinoma resection samples and created a surgery-induced underexpression of VEGF-D. VEGF-A and PlGF showed strong overexpression in carcinoma samples regardless of the sampling method. Sampling-induced hypoxia in resection samples but not in biopsy samples affects the marker-reliability of VEGF family members. Therefore, biopsy samples provide a more accurate report on VEGF family mRNA levels. Furthermore, this limited expression analysis proposes VEGF-A and PlGF as reliable, sampling procedure insensitive mRNA-markers for molecular diagnosis of colon cancer

Properties, origin and nomenclature of rodlets of the inertinite maceral group in coals of the central Appalachian basin, U.S.A.

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

The association of fungus with plant leaves and roots is ubiquitous. While many of these occurrences are considered to be pathogenic, mycorrhizzal fungal associations with roots are essential for plant growth. Despite the common knowledge of such relationships in plant science, with a few exceptions, the fungus/leaf/root/stem association as the macerals funginite, cutinite, and suberinite in coals has not been extensively studied. In this work, examples of funginite associations with cutinite and suberinite are discussed. (author)

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.

Full Text Available This study addresses the chemical composition of some commercial essential oils (clove, juniper, oregano, and marjoram oils, as well as appropriate herbal extracts obtained in the process of cold maceration and their biological activity against selected Escherichia coli strains: E. coli ATTC 25922, E. coli ATTC 10536, and E. coli 127 isolated from poultry waste. On the basis of the gas chromatography-mass spectrometry (GCMS analysis, it was found that the commercial essential oils revealed considerable differences in terms of the composition and diversity of terpenes, terpenoids and sesquiterpenes as compared with the extracts obtained from plant material. The commercial clove, oregano, and marjoram oils showed antibacterial properties against all the tested strains of E. coli. However, these strains were not sensitive to essential oils obtained from the plant material in the process of maceration. The tested strains of E. coli show a high sensitivity, mainly against monoterpenes (α-pinene, β-pinene, α,β,γ-terpinene, limonene and some terpenoids (thymol, carvacrol. The commercial juniper oil contained mainly monoterpenes and monoterpenoids, while the extracts contained lower amounts of monoterpenes and high amounts of sesquiterpenes—the anti-microbiotic properties of the juniper herbal extract seem to be caused by the synergistic activity of mono- and sesquiterpenes.

Hydropyrolysis of maceral concentrates from Shenmu coal was systematically investigated using TGA at final temperature of 900{degree}C with heating rate of 20{degree}C/min under pressure of 0.1Mpa to 3Mpa. The effect of pressure on TG/DTG curve, distribution of elements in semi-cokes and removal of sulfur and nitrogen was investigated. The results indicated that the remarkable weight loss was observed in range from 378{degree}C to 718{degree}C, the peak temperature of the maximum reaction rate was 496{degree}C and 522{degree}C for V-C and F-C respectively, and V-C has larger weight loss rate. With increasing pressure the diffusion of hydrogen increased markedly, which led to increase of weight loss. For the element distribution in the semi-coke, the C content increased, H and O content decreased, while the S content changed little. The desulfurization and denitrogenation also increased with increase in pressure. At pressure of 3 MPa, V-C had higher desulfurization than F-C. With increased pyrolysis pressure, the combustion reactivity of semi-coke first decreased and then increased. V-C semi-coke had higher combustion reactivity than F-C semi-coke under the same conditions. 8 refs., 6 figs., 3 tabs.

Full Text Available Obtaining high-quality wines with a registered designation of origin means making the most of the specific features of the variety and those imprinted with technology and the place of harvesting. The aroma is due to the chemical compounds of terpenic nature that accumulate in the grapes (variety flavors and the secondary aromas that are formed during the alcoholic fermentation and the aging period of the wines (Amrani, and Glories, 1995. The wine-making of the varieties is followed by the appreciation of the primary grapes. This is achieved by preferential maceration of the must by means of enzymes (Marin et al., 1998. The technology of aromatic wines has two fundamental objectives: extracting the primary aromas of grapes (terpenols and favoring the formation of secondary fermentation aromas. In order to obtain aromatic wines with variety typology, the preferential stage is decisive. Pectolytic enzyme preparations are used in oenology to accelerate and complete the extraction and clarification processes of the must, extracting and stabilizing the color, highlighting the varietal aromatic potential of the varieties and improving the filterability and maturation of the wines.

Fuzi Xiexin Tang (FXT) is a classic traditional Chinese medicine formula which has been employed in clinical for more than 1800 years. The distinctive preparation method (maceration) recorded in ancient time is different from one in modern clinical practice (decoction). Aim of this study is to investigate the pharmacokinetic difference of alkaloids, flavones and anthraquinones in rats after oral administration of decoction of FXT (DFXT, 30gkg(-1)), maceration of FXT (MFXT, 30gkg(-1)) and decoction of Aconiti Lateralis Radix Preparata (DAR, 6gkg(-1)) by a validated UPLC-MS/MS method. Plasma concentrations and pharmacokinetic parameters of 16 active constituents (aconitine, hypaconitine, mesaconitine, benzoylaconine, benzoylhypaconine, benzoylmesaconine, berberine, palmatine, jatrorrhizine, coptisine, baicalin, wogonin, wogonoside, emodin, aloe-emodin, rhein) in rat were quantified and compared. Different preparative methods resulted in significant difference on exposure and pharmacokinetic characteristics of alkaloids, flavones and anthraquinones from FXT, especially protoberberine alkaloids. Concentrations of monoester-diterpenoid alkaloids were below the LOD in rat plasma after administration of DFXT and MFXT because of the existence of other three herbs from FXT. Maceration could decrease the absorption of flavones while increased the absorption of anthraquinones. Cmax of emodin and rhein were 3.1 and 10.3 times increased, while eliminations of these two constituents were 8.0 and 19.0 times slower after administration of MFXT. Bioavailability of both flavones and anthraquinones increased after administration of MFXT, especially emodin and rhein increasing as much as 13.5 and 20.7 times. Herb-herb interaction between DAR and other three herbs from FXT significantly influenced the exposure of aconitum alkaloids. Copyright © 2014 Elsevier B.V. All rights reserved.

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.

Maceration enzymes and mannoproteins: a possible strategy to increase colloidal stability and color extraction in red wines.

Science.gov (United States)

Guadalupe, Zenaida; Palacios, Antonio; Ayestaran, Belén

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 objectives of this research have been to identify the pectinolytic enzymes secreted by bacteria and apply these towards the enhanced maceration and solubilization of plant material, focusing on the pectate lyases secreted by the phytopathogenic strains of Erwinia chrysanthemi, the ruminant resident Lachnospira multiparus, and the wood digestor isolate, Clostridium populeti. An HPLC approach has been developed that permits the kinetic analysis of each enzyme with respect to the formation of individual products during the pectate depolymerization process. This approach has demonstrated that each of these organisms secretes a nonrandom trimer-generating pectate lyase with a combination of endolytic and exolytic depolymerizing mechanisms. Two different strains of E. chrysanthemi secrete a battery of pectate lyases that include random endolytic as well as nonrandom dimer - and nonrandom trimer-generating endolytic/exolytic mechanisms.

Ultrasonic-assisted extraction (UAE) and maceration extraction (ME) were optimized using response surface methodology (RSM) for total phenolic compounds (TPC) from fresh olives. The main phenolic compounds and antioxidant activity of TPC were also investigated. The optimized result for UAE was 22mL/g of liquid-solid ratio, 47°C of extraction temperature and 30min of extraction time, 7.01mg/g of yielding, and for ME was 24mL/g of liquid-solid ratio, 50°C of extraction temperature and 4.7h of extraction time, 5.18mg/g of yielding. The HPLC analysis revealed that the extracts by UAE and ME possessed 14 main phenolic compounds, and UAE exhibited more amounts of all phenols than ME. The most abundant phenolic compounds in olive extracts were hydroxytyrosol, oleuropein and rutin. Both extracts showed excellent antioxidant activity in a dose-dependent manner. Taken together, UAE could effectively increase the yield of phenolic compounds from olives. In addition these phenolic compounds could be used as a potential source of natural antioxidants.

2004-12-01

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.

Radiocarbon Analysis to Calculate New End-Member Values for Biomass Burning Source Samples Specific to the Bay Area

Yoon, S.; Kirchstetter, T.; Fairley, D.; Sheesley, R. J.; Tang, X.

2017-12-01

Elemental carbon (EC), also known as black carbon or soot, is an important particulate air pollutant that contributes to climate forcing through absorption of solar radiation and to adverse human health impacts through inhalation. Both fossil fuel combustion and biomass burning, via residential firewood burning, agricultural burning, wild fires, and controlled burns, are significant sources of EC. Our ability to successfully control ambient EC concentrations requires understanding the contribution of these different emission sources. Radiocarbon (14C) analysis has been increasingly used as an apportionment tool to distinguish between EC from fossil fuel and biomass combustion sources. However, there are uncertainties associated with this method including: 1) uncertainty associated with the isolation of EC to be used for radiocarbon analysis (e.g., inclusion of organic carbon, blank contamination, recovery of EC, etc.) 2) uncertainty associated with the radiocarbon signature of the end member. The objective of this research project is to utilize laboratory experiments to evaluate some of these uncertainties, particularly for EC sources that significantly impact the San Francisco Bay Area. Source samples of EC only and a mix of EC and organic carbon (OC) were produced for this study to represent known emission sources and to approximate the mixing of EC and OC that would be present in the atmosphere. These samples include a combination of methane flame soot, various wood smoke samples (i.e. cedar, oak, sugar pine, pine at various ages, etc.), meat cooking, and smoldering cellulose smoke. EC fractions were isolated using a Sunset Laboratory's thermal optical transmittance carbon analyzer. For 14C analysis, samples were sent to Woods Hole Oceanographic Institution for isotope analysis using an accelerated mass spectrometry. End member values and uncertainties for the EC isolation utilizing this method will be reported.

There are at least 554 identified compounds in C. sativa L., among them 113 phytocannabinoids and 120 terpenes. Phytocomplex composition differences between the pharmaceutical properties of different medical cannabis chemotype have been attributed to strict interactions, defined as 'entourage effect', between cannabinoids and terpenes as a result of synergic action. The chemical complexity of its bioactive constituents highlight the need for standardised and well-defined analytical approaches able to characterise the plant chemotype, the herbal drug quality as well as to monitor the quality of pharmaceutical cannabis extracts and preparations. Hence, in the first part of this study an analytical procedures involving the combination of headspace-solid-phase microextraction (HS-SPME) coupled to GC-MS and High Resolution Mass-Spectrometry LC-HRMS (Orbitrap ® ) were set up, validated and applied for the in-depth profiling and fingerprinting of cannabinoids and terpenes in two authorised medical grade varieties of Cannabis sativa L. inflorescences (Bedrocan ® and Bediol ® ) and in obtained macerated oils. To better understand the trend of all volatile compounds and cannabinoids during oil storage a new procedure for cannabis macerated oil preparation without any thermal step was tested and compared with the existing conventional methods to assess the potentially detrimental effect of heating on overall product quality.

Although military interest in promoting psychological resilience is growing, resources protective against psychopathology have been understudied in female service members. Using a representative sample of Canadian Forces personnel, we investigated whether religious attendance, spirituality, coping, and social support were related to mental disorders and psychological distress in female service members, and whether sex differences occurred in these associations. Religious attendance and spirituality were self-reported. Coping items were taken from 3 scales and produced 3 factors (active, avoidance, and self-medication). Social support was assessed with the Medical Outcomes Study Social Support Survey. Past-year mental disorders were diagnosed with the World Mental Health Composite International Diagnostic Interview. The Kessler Psychological Distress Scale assessed distress. Multivariate regression models investigated links between correlates and psychological outcomes within each sex. For associations that were statistically significant in only one sex, sex by correlate interactions were computed. In female service members, inverse relations were found between social support and MDD, any MDD or anxiety disorder, suicidal ideation, and distress. No associations were found between religious attendance and outcomes, and spirituality was associated with an increased likelihood of some outcomes. Active coping was related to less psychological distress, while avoidance coping and self-medication were linked to a higher likelihood of most outcomes. Although several statistically significant associations were found in only one sex, only one sex by correlate interaction was statistically significant. Social support was found to be inversely related to several negative mental health outcomes in female service members. Few differences between men and women reached statistical significance. Future research should identify additional helpful resources for female service members.

Full Text Available The polygalacturonase (PGU, hemicellulase (mannanase and protease enzyme activities in commercial macerating, pectinase-enzyme preparations commonly used by wineries in Ontario (Scottzyme Color X and Color Pro were measured under various simulated process conditions (temperature, pH, and ethanol concentration. Treatments included three temperatures (15, 20 and 30 °C; pH = 3.0, 3.5, 4.0 and 5.0; ethanol = 0%, four pH levels (3.0, 3.5, 4.0 and 5.0; temperature = 15, 20, 30 and 50 °C; ethanol = 0%, and four ethanol concentrations ((2.5, 5, 7.5 and 10%; temperature = 20 °C and pH = 3.5. Polygalacturonase enzyme activity in Color X increased linearly with temperature at all pH levels, and increased with pH at all temperature regimes. Polygalacturonase activity decreased with increasing ethanol. Color X mannanase activity increased with temperatures between 15 and 40 °C, and decreased with increased pH between 3.0 and 5.0. Response of mannanase to ethanol was cubic with a sharp decrease between 8 and 10% ethanol. Protease activity increased linearly with temperatures between 20 and 40 °C. These data suggest that the PGU, mannanase and protease components in these enzyme products provide sufficient activities within the ranges of pH, temperature, and ethanol common during the initial stages of red wine fermentations, although low must temperatures (<20 °C and presence of ethanol would likely lead to sub-optimal enzyme activities.

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. Copyright © 2016. Published by Elsevier Ltd.

The effect of maceration conditions and increased solid grape parts content, seed in the first place, on the content of phenolic compounds of wine was investigated. Several micro-trials were performed with Cabernet sauvignon sort; in some variants time and temperature of maceration were varied, while the ratio of residual stem and content of seed was increased several times, resulting in a significant change of phenolic compounds content in the obtained wine samples. The presence of ripe stem yielded good results, but only during six days of maceration, while in the case of longer maceration, the change of colour quality was negative. Supplementary quantities of seeds during maceration resulted in an increase of total phenols and catechins. A significant influence on colour of wines was also observed, especially in wines obtained applying shorter maceration.

The influence of pre-fermentation cold maceration (CM) on Cabernet Sauvignon wines fermented in two different industrial-scale fermenters was studied. CM treatment had different effects on wine aroma depending on the types of fermenter, being more effective for automatic pumping-over tank (PO-tank) than automatic punching-down tank (PD-tank). When PO-tank was used, CM-treated wine showed a decrease in some fusel alcohols (isobutanol and isopentanol) and an increase in some esters (especially acetate esters). However, no significant changes were detected in these compounds when PD-tank was used. Ethyl 2-hexenoate and diethyl succinate were decreased, while geranylacetone was increased by the CM treatment in both fermenters. β-Damascenone was increased by the CM treatment in PO-tank fermented wines but decreased in PD-tank fermented wines. The fruity, caramel and floral aroma series were enhanced while chemical series were decreased by the CM treatment in PO-tank fermented wines. The content of (Z)-6-nonen-1-ol in the final wines was positively correlated to CM treatment. Copyright © 2014 Elsevier Ltd. All rights reserved.

Analyses of organic-rich mudstones from wells that penetrated the Upper Jurassic Kimmeridge Clay Formation, offshore United Kingdom, were performed to evaluate the nature of both organic and inorganic rock constituents and their relation to porosity in this world-class source rock. The formation is at varying levels of thermal maturity, ranging from immature in the shallowest core samples to mature in the deepest core samples. The intent of this study was to evaluate porosity as a function of both organic macerals and thermal maturity. At least four distinct types of organic macerals were observed in petrographic and SEM analyses and they all were present across the study area. The macerals include, in decreasing abundance: 1) bituminite admixed with clays; 2) elongate lamellar masses (alginite or bituminite) with small quartz, feldspar, and clay entrained within it; 3) terrestrial (vitrinite, fusinite, semifusinite) grains; and 4) Tasmanites microfossils. Although pores in all maceral types were observed on ion-milled surfaces of all samples, the pores (largely nanopores with some micropores) vary as a function of maceral type. Importantly, pores in the macerals do not vary systematically as a function of thermal maturity, insofar as organic pores are of similar size and shape in both the immature and mature Kimmeridge rocks. If any organic pores developed during the generation of hydrocarbons, they were apparently not preserved, possibly because of the highly ductile nature of much of the rock constituents of Kimmeridge mudstones (clays and organic material). Inorganic pores (largely micropores with some nanopores) have been observed in all Kimmeridge mudstones. These pores, particularly interparticle (i.e., between clay platelets), and intraparticle (i.e., in framboidal pyrite, in partially dissolved detrital K-feldspar, and in both detrital and authigenic dolomite) are noteworthy because they compose much of the observable porosity in the shales in both

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.

Do Low-quality Leader-Member Relationships Matter for Subordinates? Evidence from Three Samples on the Validity of the Norwegian LMX Scale

Directory of Open Access Journals (Sweden)

Trude Furunes

2015-06-01

Full Text Available Theories on the relations between leaders and subordinates have been of interest to researchers for decades; however, these theories have received less attention in the Nordic countries. The aim of this study is twofold: to investigate the validity of the Leader-Member-Exchange Scale, LMX-7, in three Norwegian samples, and to explore potentially negative relationships between leader–member relationships and work-environment quality indicators. Data were collected from teachers (n = 409, industrial workers (n = 406, and bus drivers (n = 1024. All hypotheses were supported. Results supported use of the measure LMX-7 as indicated by factor structure, high construct validity, sufficient criterion-related validity, discriminant validity, and internal reliability as measured by Cronbach’s alpha above 0.90. Poor quality relationships were associated with higher levels of role conflict, stress, bullying, turnover intentions, age discrimination, and negative affectivity, and lower levels of job satisfaction, commitment, skills utilization, autonomy, participation, perceived fairness, and social support. Potential consequences of low-quality relations and implications of findings are discussed.

Accelerated Aging of the Traditional Greek Distillate Tsipouro Using Wooden Chips. Part I: Effect of Static Maceration vs. Ultrasonication on the Polyphenol Extraction and Antioxidant Activity

Directory of Open Access Journals (Sweden)

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.

Full Text Available Flavonoids were analysed in the extracts of garden (Salvia officinalis L. and glutinous (Salvia glutinosa L. sage. Ultrasonic extraction (20 minutes at 40 °C and classical maceration (6 h at room temperature of the extractable substances from dried herbs and dried residual plant materials from which the essential oil had previously been removed by hydrodistillation were performed with petroleum ether, 70 % aqueous solution of ethanol and water. It was found that the extracts from both plants contained flavonoids, but their compositions were dependent of the plant species, the polarity of the extracting solvent and the extraction technique applied. Apigenin and its derivatives (e.g., apigenin 4'-methyl ether, scutellarein 6-methyl ether, isoscutellarein 8-methyl ether, luteolin and 6-OH-luteolin-6-methyl ether where distinctive for S. officinalis. Apigenin, luteolin, 6-OH-luteolin-6-methyl ether, kaempherol 3-methyl ether, kaempherol 3,7-dimethyl ether, quercetin 3,7,3'-trimethyl ether and quercetin 3,7,3',4'-tetramethyl ether were distinctive for S. glutinosa. The flavonoids were also detected in considerable quantities in the plant material from which the essential oils had been already removed. Hence, this industrial waste plant material might be further used as a source of the flavonoids.

Samples of economically important lignite reserves in the Ravenscrag Formation (Paleocene) of southern Saskatchewan are characterized by lithotype, maceral, microlithotype, and chemical analysis. The samples are from two cores and five reverse circulation drill boreholes from the Hart seam, Willow Bunch coalfield. Samples from four reverse circulation boreholes from the Souris seam, Estevan coalfield are characterized by maceral and chemical analysis. Coals from the Hart and Souris seams differ in rank, because of different thermal histories. A microlithotype classification developed for low rank coals is presented for Hart seam coals. 74 refs., 35 figs., 12 tabs.

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.

Respondent-driven sampling as Markov chain Monte Carlo.

Goel, Sharad; Salganik, Matthew J

2009-07-30

Respondent-driven sampling (RDS) is a recently introduced, and now widely used, technique for estimating disease prevalence in hidden populations. RDS data are collected through a snowball mechanism, in which current sample members recruit future sample members. In this paper we present RDS as Markov chain Monte Carlo importance sampling, and we examine the effects of community structure and the recruitment procedure on the variance of RDS estimates. Past work has assumed that the variance of RDS estimates is primarily affected by segregation between healthy and infected individuals. We examine an illustrative model to show that this is not necessarily the case, and that bottlenecks anywhere in the networks can substantially affect estimates. We also show that variance is inflated by a common design feature in which the sample members are encouraged to recruit multiple future sample members. The paper concludes with suggestions for implementing and evaluating RDS studies.

Petrographic Composition of Lignite from the Lake Somerville Spillway (East-central Texas)

Science.gov (United States)

Pawelec, Sandra; Bielowicz, Barbara

2017-12-01

In the presented paper, the macroscopic and microscopic composition of lignite from Lake Somerville Spillway has been examined. The study area is the upper part of the Manning Formation, located north-west of Somerville in the central-eastern part of Texas. There are three exposures: NE, SW and MC (Main Central) with visible parts of late-Eocene lignite seams belonging to the Jackson Group. The Manning section is divided into four marine dominated parasequences (P1 through P4). Lignite samples outlining the P1 parasequence from the MC and NE outcrops and the argillate sample from the lower part of the P2 parasequence, NE outcrop. Macroscopic characterization was carried out based on lithological classifications of humic coal. On this basis, it has been shown that the main lithotype occurring in the deposit is detritic (matrix) coal with a high share of mineral matter. The maceral composition of coal was determined according to the ICCP guidelines. The macerals from liptinite group were determined under fluorescent light. The maceral group content analysis was performed with use of 500-600 equally spaced points on the surface of the polished sections. It has been found that the examined coal is dominated by macerals from the huminite group, with a share ranging from 20.8 to 65.3% volume, including atrinite (9.8-22.8% volume, 17.5% volume on average). In the examined coal, macerals from the inertinite group (10.1 to 44.8%), especially semifusinite (max. 13.9%), fusinite (max. 9.3%) and funginite (max. 6.3 %) are of particularly large share. In the liptinite group, particular attention was paid to the content of alginite (max. 4.5%) and bituminite (max. 1.3 %), which indicate the paralic sedimentation environment of the examined coal. Additionally, the variability of macerals and maceral groups within the exposures and levels of the P1 parasequence was examined. The last step was to compare lignite from Lake Somerville Spillway with other lignites belonging to the

2015-07-22

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.

The shape modulation of osteoblast-osteocyte transformation and its correlation with the fibrillar organization in secondary osteons: a SEM study employing the graded osmic maceration technique.

Science.gov (United States)

Pazzaglia, Ugo E; Congiu, Terenzio; Marchese, Marcella; Dell'Orbo, Carlo

2010-06-01

Cortex fractured surface and graded osmic maceration techniques were used to study the secretory activity of osteoblasts, the transformation of osteoblast to osteocytes, and the structural organization of the matrix around the cells with scanning electron microscopy (SEM). A specialized membrane differentiation at the base of the cell was observed with finger-like, flattened processes which formed a diffuse meshwork. These findings suggested that this membrane differentiation below the cells had not only functioned in transporting collagen through the membrane but also in orienting the fibrils once assembled. Thin ramifications arose from the large and flat membrane foldings oriented perpendicular to the plane of the osteoblasts. This meshwork of fine filaments could not be visualized with SEM because they were obscured within the matrix substance. Their 3-D structure, however, should be similar to the canalicular system. The meshwork of large, flattened processes was no more evident in the cells which had completed their transformation into osteocytes.

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.

The origin and distribution of HAPs elements in relation to maceral composition of the A1 lignite bed (Paleocene, Calvert Bluff Formation, Wilcox Group), Calvert mine area, east-central Texas

1997-01-01

The origin and distribution of twelve potentially Hazardous Air Pollutants (HAPs; As, Be, Cd, Cr, Co, Hg, Mn, Ni, Pb, Sb, Se, and U) identified in the 1990 Clean Air Act Amendments were examined in relation to the maceral composition of the A1 bed (Paleocene, Calvert Bluff Formation, Wilcox Group) of the Calvert mine in east-central Texas. The 3.2 m-thick A1 bed was divided into nine incremental channel samples (7 lignite samples and 2 shaley coal samples) on the basis of megascopic characteristics. Results indicate that As, Cd, Cr, Ni, Pb, Sb, and U are strongly correlated with ash yield and are enriched in the shaley coal samples. We infer that these elements are associated with inorganic constituents in the coal bed and may be derived from a penecontemporaneous stream channel located several kilometers southeast of the mining block. Of the HAPs elements studied, Mn and Hg are the most poorly correlated to ash yield. We infer an organic association for Mn; Hg may be associated with pyrite. The rest of the trace elements (Be, Co, and Se) are weakly correlated with ash yield. Further analytical work is necessary to determine the mode of occurrence for these elements. Overall, concentrations of the HAPs elements are generally similar to or less than those reported in previous studies of lignites of the Wilcox Group, east-central region, Texas. Petrographic analysis indicates the following ranges in composition for the seven lignite samples: liptinites (5–8%), huminites (88–95%), and inertinites (trace amounts to 7%). Samples from the middle portion of the A1 bed contain abundant crypto-eugelinite compared to the rest of the samples; this relationship suggests that the degradation of plant material was an important process during the development of the peat mire. With the exception of Hg and Mn, relatively low levels of the HAPs elements studied are found in the samples containing abundant crypto-eugelinite. We infer that the peat-forming environment for this

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.

Full Text Available Pubagem é a fermentação natural de raízes de mandioca para produção da puba, um alimento popular do Nordeste do Brasil. Além da fermentação lática predominante, os microrganismos também causam o amolecimento das raízes, importante para a obtenção de um produto de boa qualidade. O objetivo deste trabalho foi detectar a presença de enzimas de maceração e verificar a influência da adição de preparados comerciais de celulase e pectinase na pubagem. Constatou-se que as atividades de celulases, xilanase e poligalacturonase aumentaram durante a fermentação natural. Ao se adicionar preparados comerciais de celulase e pectinase este aumento foi maior do que o esperado pela fermentação natural. A adição desses preparados enzímicos acelerou a fermentação aumentando a acidez e reduzindo o pH mais rapidamente do que o tratamento-testemunha.Retting is the natural fermentation of cassava for the production of puba, a common food of the Northeast of Brazil.

The objective of this work was to detect the presence of macerating enzymes and to verify the influence of the addition of a commercial preparation of cellulase and pectinase on the retting of cassava. It was found that the activities of cellulases, xilanase and poligalacturonase increased during natural fermentation. This increase was higher than that expected by natural fermentation when commercial preparations of cellulase and pectinase were added. The additions of these enzymic preparations speeded up the fermentation process increasing the acidity and reducing the pH more rapidly than in the control samples.

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.

1991-09-01

A national sample of 500 members of Gamblers Anonymous was surveyed by mail in order to gather information on suicidal history. One hundred sixty two usable surveys were returned representing 32.4% of the original sample. Compulsive gamblers who had a history of suicidal preoccupation began gambling at an earlier age than nonsuicidal gamblers and were more likely to have stolen to support their gambling. They also tended to have addicted relatives and children more than nonsuicidal gamblers did. The data suggest that those gamblers who had been suicidal tend to be more serious gamblers than nonsuicidal respondents.

Petrographic properties of major coal seams in Turkey and their formation

Energy Technology Data Exchange (ETDEWEB)

Toprak, Selami [Mineral Research and Exploration Directorate (MTA), 06520 Ankara (Turkey)

2009-06-01

Most types of coal in Turkey are generally low in rank: lignite, and subbituminous. Most of the coal was formed during the Miocene, Eocene, and Pliocene ages. There are only a few thin Jurassic-age coal occurrences in Turkey. Pennsylvanian age bituminous coal is found on the Black Sea coast. General implications of the petrographic properties of Turkey's coal seams and coal deposits have not yet been taken into consideration comparatively or as a whole. For this study, about 190 channel samples were collected from different locales. The composite profile samples of the seams were taken into considerations. The content and depositional properties as well as some chemical and physical properties of the main coal seams are compared. All coal samples tend to have similar coal petrographic properties and were deposited in intermontane lacustrine basins. Later, they were affected by faulting and post-depositional volcanic activity. As a result, there are variations in the properties and rank of the coal samples. The most abundant coal maceral group is huminite and the most abundant maceral is gelinite. The liptinite and inertinite contents of the coal are low and the maceral contents of the coals show great similarity. The depositional environments of the all coals are lacustrine dominated.

Somers, G.; Stassun, K. G.

2018-04-01

We began with the newly assembled catalog of literature lithium measurements reported by Barrado et al. (2016, J/A+A/596/A113), who accepted only stars with membership probability >0.75. A small number of Pleiads lie behind an HI cloud, and are thus far more extincted than the rest (e.g., Gordon & Arny 1984AJ.....89..672G); for simplicity, we discard these members. We then cross-correlated this sample with the famous UBV photometric catalog of Johnson & Mitchell (1958ApJ...128...31J), who produced homogeneous photometry for a large sample of Pleiades members. We further selected stars with measured rotation rates, either from the HATNet collaboration (Hartman et al. 2010, J/MNRAS/408/475), or the recent analysis of K2 data (Rebull et al. 2016, J/AJ/152/113, J/AJ/152/114; Stauffer et al. 2016, J/AJ/152/115), preferring the latter for joint detections. Finally, we queried VizieR (http://vizier.u-strasbg.fr/) to obtain KS-band magnitudes from the Two-Micron All-Sky Survey (2MASS) catalog (Skrutskie et al. 2006, Cat. VII/233), which detected every star in our reduced sample. These criteria produced a total of 83 high-probability cluster members, stretching from early-F to late-K type. (3 data files).

Cytogenetic effects of ionizing radiation in peripheral lymphocytes of ISS crew members

Science.gov (United States)

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.

Mentoring relationships, for all medical school faculty members, are an important component of lifelong development and education, yet an understanding of mentoring among medical school clinical faculty members is incomplete. This study examined associations between formal mentoring relationships and aspects of faculty members' engagement and satisfaction. It then explored the variability of these associations across subgroups of clinical faculty members to understand the status of mentoring and outcomes of mentoring relationships. The authors hypothesised that academic clinical faculty members currently in formal mentoring relationships experience enhanced employee engagement and satisfaction with their department and institution. Medical school faculty members at 26 self-selected USA institutions participated in the 2011-2014 Faculty Forward Engagement Survey. Responses from clinical faculty members were analysed for relationships between mentoring status and perceptions of engagement by faculty members. Of the 11 953 clinical faculty respondents, almost one-third reported having a formal mentoring relationship (30%; 3529). Most mentored faculty indicated the relationship was important (86%; n = 3027), and over three-fourths were satisfied with their mentoring experience (77%; n = 2722). Mentored faculty members across ranks reported significantly higher levels of satisfaction and more positive perceptions of their roles in the organisation. Faculty members who were not receiving mentoring reported significantly less satisfaction with their workplace environment and lower overall satisfaction. Mentored clinical faculty members have significantly greater satisfaction with their department and institution. This multi-institutional study provides evidence that fostering mentoring opportunities may facilitate faculty members' satisfaction and engagement, which, in turn, may help medical schools retain high-quality faculty staff committed to the multidimensional

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.

Full Text Available Background. The admission of a relative to an intensive care unit (ICU is a stressful experience for family members. There has been limited research addressing this issue in Kigali, Rwanda.Objective. To explore the needs of patient family members admitted into an ICU in Kigali, Rwanda.Methods. This study used a quantitative exploratory design focused on exploring the needs of patient family members in ICU at one hospital in Kigali, Rwanda. Family members (N=40 were recruited using the convenience sampling strategy. The Critical Care Family Needs Inventory was used to collect relevant data.Results. The participants identified various needs to be met for the family during the patient’s admission in ICU. The most important was the need for assurance, followed by the need for comfort, information, proximity and lastly support. Three additional needs specific to this sample group were also identified, related to resource constraints present in the hospital where the study was carried out.Conclusion. These results offer insight for nurses and other healthcare professionals as to what the important needs are that must be considered for the patient family members in ICUs within a resource-constrained environment.

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.

Burnout prediction using advance image analysis coal characterization techniques

Edward Lester; Dave Watts; Michael Cloke [University of Nottingham, Nottingham (United Kingdom). School of Chemical Environmental and Mining Engineering

2003-07-01

The link between petrographic composition and burnout has been investigated previously by the authors. However, these predictions were based on 'bulk' properties of the coal, including the proportion of each maceral or the reflectance of the macerals in the whole sample. Combustion studies relating burnout with microlithotype analysis, or similar, remain less common partly because the technique is more complex than maceral analysis. Despite this, it is likely that any burnout prediction based on petrographic characteristics will become more accurate if it includes information about the maceral associations and the size of each particle. Chars from 13 coals, 106-125 micron size fractions, were prepared using a Drop Tube Furnace (DTF) at 1300{degree}C and 200 millisecond and 1% Oxygen. These chars were then refired in the DTF at 1300{degree}C 5% oxygen and residence times of 200, 400 and 600 milliseconds. The progressive burnout of each char was compared with the characteristics of the initial coals. This paper presents an extension of previous studies in that it relates combustion behaviour to coals that have been characterized on a particle by particle basis using advanced image analysis techniques. 13 refs., 7 figs.

Helping concerned family members of individuals with substance use and concurrent disorders: An evaluation of a family member-oriented treatment program.

Science.gov (United States)

Denomme, William James; Benhanoh, Orry

2017-08-01

There is a growing body of research demonstrating that families of individuals with substance use and concurrent disorders (SUCD) experience a wide range of biopsychosocial problems that significantly impedes their quality of life and health. However, there has been a relative lack of treatment programs primarily focused on improving the well-being and quality of life of these family members. The current study assessed the efficacy of such a program at reducing stress, increasing perceived social support from family and friends, and increasing general, dyadic, and self-rated family functioning within these concerned family members. A sample of 125 family members of individuals with SUCDs was recruited, of which 97 participated in the treatment program and 28 were used as the comparison group. Results indicated that the treatment program significantly reduced stress, increased perceived social support from family and friends, and increased general, dyadic and self-rated family functioning. A perceived personal benefits questionnaire demonstrated that participants had a better understanding of SUCDs, better coping capabilities in regard to emotional difficulties, adopted stronger coping methods, participated in more leisure activities, and improved their relationship with the individual with a SUCD. The results of the current study further demonstrate the need to implement more of these family-member oriented psycho-educational treatment programs. Copyright © 2017 Elsevier Inc.

1987-07-01

The radioactive debris cloud from the Chernobyl reactor accident resulted in some deposition over essentially all of the Northern Hemisphere. Shortly after the accident invitations were sent out by the IAEA to Member States to collect grass samples according to specific instructions so that the ratio of the various radionuclides in the fallout debris could be established over a wide area of Europe. In response to this request, 20 grass samples were provided by Member States. To establish a protocol for analysis of these valuable samples and to recommend a protocol for future sample collection, a Consultants Meeting was called by the IAEA for 23-25 September 1986. This document contains the considerations and recommendations of the consultants

Food banks provide supplemental food to low-income households, yet little is known about the cardiovascular health of food banks members. This study therefore described cardiovascular disease (CVD) risk factors among food bank members and explored associations between food insecurity and CVD risk. Adults ≥18 years (n = 77) from three food bank sites in metro Vancouver, British Columbia completed surveys and physical assessments examining a range of socio-demographic variables and CVD risk factors. A composite measure of myocardial infarction (MI) risk called the INTERHEART score was assessed and household food insecurity was measured using the Household Food Security Survey Module. Regression models were used to explore associations between food insecurity and CVD risk measures, including the INTERHEART score. Ninety-seven percent of food bank members reported experiencing food insecurity, 65% were current smokers, 53% reported either chronic or several periods of stress in the past year, 55% reported low physical activity levels and 80% reported consuming fewer than five servings of fruit and vegetables daily. Prevalence of self-reported diabetes and hypertension were 13% and 29% respectively. Fifty-two percent of the sample were at high risk of non-fatal MI. No statistically significant associations were found between increased severity of food insecurity and CVD risk factors among this sample where both severe food insecurity and high CVD risks were prevalent. Food bank members were at elevated risk for CVD compared with the general population. Strategies are needed to reduce prevalence of food insecurity and CVD risk factors, both of which disproportionately affected food bank members.

Holmbeck, Erika; Vican, Laura

2014-06-01

Our group has assembled a sample of 14,000 stars of spectral types B9-M9 with measured UVW Galactic space velocities and lying within 125 pc of Earth. We have identified candidate members of three nearby young (less than 100 Myr) moving groups. For stars of spectral types G5 and later, we have used the Kast spectrometer on the Shane 3m telescope at Lick Observatory to measure lithium abundance in order to determine stellar ages. With the data we have obtained from this run, we will be able to establish whether our candidates are bona fide members of the moving groups in question. I will be presenting the preliminary results from this survey, including spectra of the ~50 stars observed thus far. These nearby young stars will make excellent targets for direct imaging followup surveys, since any giant planets around young stars will still be warm, and will therefore be bright enough to detect with instruments like GPI.

Evaluation of Reinforced Concrete Structural Members under Uniform Loads Using Truss Model

Directory of Open Access Journals (Sweden)

Houshang Dabbagh

2016-03-01

Full Text Available Truss model is an analytical approach to predict the strength of reinforced concrete members with geometric or statical discontinuous regions. This study investigates the use of truss model to predict the structural behavior of reinforced concrete members with discontinuity areas under monotonic loading. The estimated failure load and its corresponding deformation are the main objective of this research. Twenty and three samples including short shear walls, short columns and deep beams tested by other researchers throughout the literature have been selected. Then their truss models as well as their three dimensional finite element models are analyzed using ABAQUS software. The comparison of experimental and analytical results shows fair correlation between them. Also, the structural response of samples estimated by truss model analysis is fairly acceptable.

Este efeito é atribuído aos polifenóis presentes no vinho, em especial ao resveratrol (3,5,4'-triidroxiestilbeno, que é uma fitoalexina encontrada em várias partes da videira, principalmente na casca da uva, assim como em outras espécies de plantas. Uvas da cultivar Cabernet Sauvignon foram submetidas à irradiação com luz ultravioleta e maceração carbônica e após fermentadas. Procedeu-se à coleta de amostras durante todo o experimento, as quais foram posteriormente analisadas quanto ao teor de trans-resveratrol através da Cromatografia Líquida de Alta Eficiência. Os resultados do trabalho demonstram que a evolução do conteúdo de trans-resveratrol foi ascendente durante as fases da fermentação. Diferenças ocorreram no final da fermentação, em que as amostras de vinhos com maceração carbônica apresentaram leve declínio, possivelmente pela atmosfera de CO2 na qual ficaram armazenadas, inibindo a formação do resveratrol. Ao final da fermentação principal a concentração de trans-resveratrol foi de 15 mg.L-1 em todos os tratamentos, chegando a 1,5 mg.L-1, em média, no final do período de estocagem.The moderate consumption of wine reduces the risks of heart diseases significantly.

University faculty members of different disciplines in any country, by giving better quality services, will further accelerate the development of their respective countries. This study aims to explore the experiences of faculty members about their professional challenges. In this qualitative study, which was conducted in 2013, fifteen faculty members in the departments of clinical and basic sciences of Mazandaran university of Medical Sciences in northern Iran were chosen for semi-structured in-depth interviews by purposive sampling method. All tape-recorded data were fully transcribed and content analysis was performed. AFTER IMMERSION AND DATA ANALYSIS, THREE MAIN THEMES WERE EMERGED INCLUDING: "Imbalances in academic members' tasks in different areas", "Weakness of evaluation and promotion system" and "Failure to provide the infrastructure educational facilities". The main themes and sub-themes are explained by the help of participants' direct quotations. This study suggested that it is better to take effective measures to improve the faculty members' situation and therefore increase their efficiency, effectiveness and productivity.

2012-05-10

To identify the benefits and consequences of having part-time faculty members in departments of pharmacy practice from the department chair's perspective. A stratified purposive sample of 12 pharmacy practice department chairs was selected. Eleven telephone interviews were conducted. Two investigators independently read interview notes and categorized and enumerated responses to determine major themes using content analysis. The investigators jointly reviewed the data and came to consensus on major themes. Benefits of allowing full-time faculty members to reduce their position to part-time included faculty retention and improved individual faculty work/life balance. Consequences of allowing part-time faculty positions included the challenges of managing individual and departmental workloads, the risk of marginalizing part-time faculty members, and the challenges of promotion and tenure issues. All requests to switch to part-time status were faculty-driven and most were approved. There are a variety of benefits and consequences of having part-time faculty in pharmacy practice departments from the chair's perspective. Clear faculty and departmental expectations of part-time faculty members need to be established to ensure optimal success of this working arrangement.

2018-06-01

Full Text Available Food banks provide supplemental food to low-income households, yet little is known about the cardiovascular health of food banks members. This study therefore described cardiovascular disease (CVD risk factors among food bank members and explored associations between food insecurity and CVD risk.Adults ≥18 years (n = 77 from three food bank sites in metro Vancouver, British Columbia completed surveys and physical assessments examining a range of socio-demographic variables and CVD risk factors. A composite measure of myocardial infarction (MI risk called the INTERHEART score was assessed and household food insecurity was measured using the Household Food Security Survey Module. Regression models were used to explore associations between food insecurity and CVD risk measures, including the INTERHEART score.Ninety-seven percent of food bank members reported experiencing food insecurity, 65% were current smokers, 53% reported either chronic or several periods of stress in the past year, 55% reported low physical activity levels and 80% reported consuming fewer than five servings of fruit and vegetables daily. Prevalence of self-reported diabetes and hypertension were 13% and 29% respectively. Fifty-two percent of the sample were at high risk of non-fatal MI. No statistically significant associations were found between increased severity of food insecurity and CVD risk factors among this sample where both severe food insecurity and high CVD risks were prevalent.Food bank members were at elevated risk for CVD compared with the general population. Strategies are needed to reduce prevalence of food insecurity and CVD risk factors, both of which disproportionately affected food bank members. Keywords: Food insecurity, Food banks, Cardiovascular disease, Risk factors, Canada

222Rn and 220Rn concentrations measured in various natural honey samples by using nuclear track detectors and resulting radiation doses to the members of the rural populations in Morocco

International Nuclear Information System (INIS)

Misdaq, M. A.; Mortassim, A.

2008-01-01

Radon ( 222 Rn) and thoron ( 220 Rn) concentrations were measured in sixteen natural honey material samples collected from different regions in Morocco by using CR-39 and LR-115 type II solid state nuclear track detectors (SSNTDs). The concentrations of these radionuclides were also measured in nectar solutions corresponding to the studied honey samples. The measured concentrations of 222 Rn and 220 Rn in honey samples ranged from (2.3 ± 0.2) to (8.1 ± 0.6) Bq.l -1 and (1.8 ± 0.1) to (3.9 ± 0.3) Bq.l -1 , respectively. Committed equivalent doses due to annual intakes of 222 Rn were evaluated in the human gastrointestinal tract compartments of adult members of the Moroccan populations from the ingestion of studied honey samples. The influence of the target tissue mass and activities due to 222 Rn on the annual committed equivalent doses in the compartments of the human gastrointestinal tract was investigated. (authors)

We report on the properties of pre-main-sequence objects in the Taurus molecular clouds as observed in seven 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 deg 2 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 bona fide 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 new candidate members of Taurus. We have obtained follow-up spectroscopy for about half the candidate sample, thus far confirming 34 new members, three probable new members, and 10 possible new members, an increase of 15%-20% in Taurus members. Of the objects for which we have spectroscopy, seven are now confirmed extragalactic objects, and one is a background Be star. The remaining 93 candidate objects await additional analysis and/or data to be confirmed or rejected as Taurus members. Most of the new members are Class II M stars and are located along the same cloud filaments as the previously identified Taurus members. Among non-members with Spitzer colors similar to young, dusty stars are evolved Be stars, planetary nebulae, carbon stars, galaxies, and active galactic nuclei.

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.

The PIXE (proton-induced X-ray emission) microprobe can be used for nondestructive, in-situ analyses of areas as small as those analyzed by the electron microprobe, and has a sensitivity of detection as much as two orders of magnitude better than the electron microprobe. Preliminary studies demonstrated that PIXE provides a capability for quantitative determination of elemental concentrations in individual coal maceral grains with a detection limit of 1-10 ppm for most elements analyzed. Encouraged by the earlier results, we carried out the analyses reported below to examine trace element variations laterally (over a km range) as well as vertically (cm to m) in the I and J coal beds in the Upper Cretaceous Ferron Sandstone Member of the Mancos Shale in central Utah, and to compare the data with the data from two samples of eastern coals of Pennsylvanian age.

Soil sampling and analysis for radionuclides after an accidental or routine release is a key factor for the dose calculation to members of the public, and for the establishment of possible countermeasures. The IAEA organized for selected laboratories of the ALMERA (Analytical Laboratories for the Measurement of Environmental Radioactivity) network a Soil Sampling Intercomparison Exercise (IAEA/SIE/01) with the objective of comparing soil sampling procedures used by different laboratories. The ALMERA network is a world-wide network of analytical laboratories located in IAEA member states capable of providing reliable and timely analysis of environmental samples in the event of an accidental or intentional release of radioactivity. Ten ALMERA laboratories were selected to participate in the sampling exercise. The soil sampling intercomparison exercise took place in November 2005 in an agricultural area qualified as a 'reference site', aimed at assessing the uncertainties associated with soil sampling in agricultural, semi-natural, urban and contaminated environments and suitable for performing sampling intercomparison. In this paper, the laboratories sampling performance were evaluated.

Full Text Available Background and purpose: Evaluation of faculty members is a kind of educational evaluation to determine success of faculty members in reaching the educational goals. Regarding the controversy about the validity of this kind of evaluation, this study was done to examine faculty members and students view point about content and implementation of evaluation of faculty members by students and feedback of the results in the second term of academic year 2003-4 in Birjand University of Medicine.Methods: All faculty members and students participated in this descriptive study. Their opinions were studied using two questionnaires for students and faculty members separately, whose content validity were confirmed after a survey from specialists and pilot study and reliability of results werestudied through calculating Cronbach’s alpha coefficient for internal consistency .Data were analyzed through calculating frequencies and K2-test, α=0.05.Results: Of all faculty members, 95% ( 30 from clinical and 30 from non clinical departments were aware of having been evaluated by students, 81.7% of them recognize educational development center of the University as the responsible body for evaluation. 91.7% of them received the feedback of the evaluation results. 45% of them agreed that announcement of evaluation results was helpful to improve teaching. 40% believed that questionnaires were responded without dutifulness andcarefulness by students.Conclusion: The aim of teaching evaluation is to improve teaching by faculty members. But it seems that many faculty members do not regard this evaluation tool so valid for measuring their teaching activities. The inappropriateness of most of the questionnaires, unfair judgment of student, and careless selection of the sample of students who answer the questionnaires are major issues for further development.Key words: EVALUATION, FACULTY MEMBER, STUDENT, MEDICAL UNIVERSITY OF BIRJAND

In recent years, several limitations as to the application of end member mixing analysis with isotope and geochemical tracers have been revealed: unstable end member solutions, inputs varying in space and time, and unrealistic mixing assumptions. In addition, the necessary high-frequency sampling using conventional methods is time and resources consuming, and hence most sampling rates are not suitable for capturing the response times of the majority of observed headwater catchments. However, high-frequency observations are considered fundamental for gaining new insights into hydrological systems. In our study, we have used two portable, in situ, high-frequency UV-Vis spectrometers (spectro::lyser; scan Messtechnik GmbH) to investigate the variability of several signatures in streamflow and end member stability. The spectro::lyser measures TOC, DOC, nitrate and the light absorption spectrum from 220 to 720 nm with 2.5 nm increment. The Weierbach catchment (0.45 km2) in the Attert basin (297 km2) in Luxemburg is a small headwater research catchment (operated by the CRP Gabriel Lippmann), which is completely forested and underlain by schist bedrock. The catchment is equipped with a dense network of hydrological instruments and for this study, the outlet of the Weierbach catchment was equipped with one spectro::lyser, permanently sensing stream water at a 15 minutes time step over several months. Hydrometric and meteorologic data was compared with the high-frequency spectro::lyser time series of TOC, DOC, nitrate and the light absorption spectrum, to get a first insight into the behaviour of the catchment under different environmental conditions. As a preliminary step for a successful end member mixing analysis, the stability of rainfall, soil water, and groundwater was tested with one spectro::lyser, both temporally and spatially. Thereby, we focused on the investigation of changes and patterns of the light absorption spectrum of the different end members and the

DIFFERENT STROKES FOR DIFFERENT GANGS? AN ANALYSIS OF CAPITAL AMONG LATINO AND ASIAN GANG MEMBERS

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

Circular replication-associated protein encoding single-stranded DNA (CRESS DNA) viruses are increasingly recognized worldwide in a variety of samples. Representative members include well-described veterinary pathogens with worldwide distribution, such as porcine circoviruses or beak and feather disease virus. In addition, numerous novel viruses belonging to the family Circoviridae with unverified pathogenic roles have been discovered in different human samples. Viruses of the family Genomoviridae have also been described as being highly abundant in different faecal and environmental samples, with case reports showing them to be suspected pathogens in human infections. In order to investigate the genetic diversity of these viruses in European bat populations, we tested guano samples from Georgia, Hungary, Romania, Serbia and Ukraine. This resulted in the detection of six novel members of the family Circoviridae and two novel members of the family Genomoviridae. Interestingly, a gemini-like virus, namely niminivirus, which was originally found in raw sewage samples in Nigeria, was also detected in our samples. We analyzed the nucleotide composition of members of the family Circoviridae to determine the possible host origins of these viruses. This study provides the first dataset on CRESS DNA viruses of European bats, and members of several novel viral species were discovered.

Stress Reduction in Postcardiac Surgery Family Members: Implementation of a Postcardiac Surgery Tool Kit.

Science.gov (United States)

Breisinger, Lauren; Macci Bires, Angela; Cline, Thomas W

The intensive care unit (ICU) can be a place of stress, anxiety, and emotional instability for both patients and families. Medical and nursing care during this acute time is patient focused, and family members are often left in the dark. Unintentional exclusion from information results in high levels of stress, anxiety, and uncertainty for families. Due to the acuity of illness, family members of cardiac surgery patients experience the highest levels of stress. Spouses may experience intense psychosomatic symptoms such as depression, anxiety, and fear for several months after the surgery. The purpose of this study was aimed at decreasing those feelings of anxiety in family members with postcardiac surgery through the use of a cardiac surgery tool kit. The study was a quality improvement project utilizing a convenience sample of 83 participants 18 years and older. Participants were asked to use the State Trait Anxiety Inventory (STAI) Form Y-1 (state anxiety) to rate their anxiety level preintervention and then again postintervention. Data were collected over a 6-month period. Descriptive data including age, education level, ethnicity, relationship, experience in the ICU, and active diagnoses of mental disorders did not affect the changes in the pre- and posttest data. A paired t test was conducted on the sample to assess changes in state anxiety, using the STAI Form Y-1. The results were statistically significant (t = 11.97, df = 81, P family members of postcardiac surgery patients.

A fluid sampling tool for sampling fluid from a container. The tool has a fluid collecting portion which is drilled into the container wall, thereby affixing it to the wall. The tool may have a fluid extracting section which withdraws fluid collected by the fluid collecting section. The fluid collecting section has a fluted shank with an end configured to drill a hole into a container wall. The shank has a threaded portion for tapping the borehole. The shank is threadably engaged to a cylindrical housing having an inner axial passageway sealed at one end by a septum. A flexible member having a cylindrical portion and a bulbous portion is provided. The housing can be slid into an inner axial passageway in the cylindrical portion and sealed to the flexible member. The bulbous portion has an outer lip defining an opening. The housing is clamped into the chuck of a drill, the lip of the bulbous section is pressed against a container wall until the shank touches the wall, and the user operates the drill. Wall shavings (kerf) are confined in a chamber formed in the bulbous section as it folds when the shank advances inside the container. After sufficient advancement of the shank, an o-ring makes a seal with the container wall.

Validity of historical simulation in EU new member and candidate states

Directory of Open Access Journals (Sweden)

Heri Bezić

2007-01-01

Full Text Available Market risk arises from movement in the underlying risk factors of a particular security, such as: equity prices, interest rates, exchange rates and commodity prices. With the approval of Basle Committee for Banking Supervision and European Commission on using internally developed market risk measurement models to calculate bank’s market risk provisions, the interest for market risk models has significantly increased. Because financial markets of EU new member and candidate states significantly differ from the developed markets, applying VaR models developed and tested in the developed and liquid financial markets, to the volatile and shallow financial markets of EU new member and candidate states is highly questionable. This paper tests whether using a wide spread market risk measurement model such as Historical simulation adequately measures the market risk in stock markets of EU new member and candidate states. In this paper, the stock market indexes of Bulgaria, Romania, Croatia and Turkey are used to test the adequacy of measuring market risk based on Historical simulation. The testing is performed out of the sample, with four different observation periods.

Permeability and fluid chemistry studies of the Topopah Spring Member of the Paintbrush Tuff, Nevada Test Site: Part II

International Nuclear Information System (INIS)

Moore, D.E.; Morrow, C.A.; Byerlee, J.D.

1985-03-01

The Topopah Spring Member of the Paintbrush Tuff is being considered as a possible emplacement horizon for the disposal of nuclear waste. The permeability and pore-fluid chemistry of the Topopah Spring Member have been investigated experimentally. The work reported here represents a continuation of previous permeability studies on the Topopah Spring Member. Three experiments were run, to test the effect of pore pressure, sample orientation, and flow direction on permeability and pore fluid chemistry. In the experiments, water flowed either up or down a temperature gradient established across the tuff sample in response to a small pore pressure gradient. The maximum temperature of the gradient was 150 0 C, and the minimum was 43 to 45 0 C. The confining pressure was 100 bars, corresponding to a disposal depth of 400 meters. J13 water was the starting pore fluid. The heated tuff samples showed few changes in permeability from their initial, room-temperature values. In addition, the fluids discharged from both the low and high-temperature sides of the tuff samples were dilute, nearly neutral solutions whose compositions did not differ greatly from the starting J13 compositions. 16 refs., 14 figs., 4 tabs

Thermal effects in concrete members

International Nuclear Information System (INIS)

Kar, A.K.

1977-01-01

The proposed method of analysis for concrete members subjected to temperature changes is consistent with the requirements of ultimate strength design. This also facilitates the provision of the same safety margin as for other loads. Due to cracks and creep in concrete, thermal stresses are nonlinear; they are dependent on the effective member stiffness, which in turn vary with the magnitude of loading. Therefore it is inconsistent to have an ultimate strength design in conjunction with an analysis based on the linear elastic theory. It is proposed that when the requirements of serviceability are met, the neutral axis corresponding to the ultimate load capacity conditions be considered for temperature-induced loadings. This conforms with the fact that the thermal load, because of creep and formation of cracks in the member, can be self-relieving as the failure load condition or ultimate capacity is approached. The maximum thermal load that can develop in dependent on the effective cross section of the member. Recommendations are made for determining the average effective member stiffness, which lies between the stiffness corresponding to the cracked (at ultimate condition) and the uncracked sections. In the proposed method, thermal stresses are not considered completely self-relieving. The stresses are considered simultaneously with stresses resulting from other causes. A step-by-step approach is presented for analysis and design of concrete members subjected to temperature changes

Inductive reasoning involves generalization from sample observations to categories. This research examined the conditions under which generalizations go beyond the boundaries of the sampled categories. In Experiment 1, participants sampled colored chips from urns. When categorization was not salient, participants revised their estimates of the probability of a particular color even in urns they had not sampled. As categorization became more salient, generalization became limited to the sampled urn. In Experiment 2 the salience of categorization in social induction was varied. When social categorization was not salient, participants projected their own responses to test items to members of a laboratory group even when they themselves did not belong to this group. When salience increased, projection decreased among nonmembers but not among members. In Experiment 3 these results were replicated in a field setting.

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

Directory of Open Access Journals (Sweden)

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.

The ICU is a complex and stressful environment and is associated with significant psychologic morbidity for patients and their families. We sought to determine whether salivary cortisol, a physiologic measure of acute stress, was associated with subsequent psychologic distress among family members of ICU patients. This is a prospective, observational study of family members of adult ICU patients. Adult medical and surgical ICU in a tertiary care center. Family members of ICU patients. Participants provided five salivary cortisol samples over 24 hours at the time of the patient ICU admission. The primary measure of cortisol was the area under the curve from ground; the secondary measure was the cortisol awakening response. Outcomes were obtained during a 3-month follow-up telephone call. The primary outcome was anxiety, measured by the Hospital Anxiety and Depression Scale-Anxiety. Secondary outcomes included depression and posttraumatic stress disorder. Among 100 participants, 92 completed follow-up. Twenty-nine participants (32%) reported symptoms of anxiety at 3 months, 15 participants (16%) reported depression symptoms, and 14 participants (15%) reported posttraumatic stress symptoms. In our primary analysis, cortisol level as measured by area under the curve from ground was not significantly associated with anxiety (odds ratio, 0.94; p = 0.70). In our secondary analysis, however, cortisol awakening response was significantly associated with anxiety (odds ratio, 1.08; p = 0.02). Roughly one third of family members experience anxiety after an ICU admission for their loved one, and many family members also experience depression and posttraumatic stress. Cortisol awakening response is associated with anxiety in family members of ICU patients 3 months following the ICU admission. Physiologic measurements of stress among ICU family members may help identify individuals at particular risk of adverse psychologic outcomes.

Desirable health is impossible without good nutrition, and Allah has addressed us on eating foods in 118 verses. This study aimed to describe the medical university faculty members' perceptions of nutritional health in the Quran, revealing the important role of faculty members. This qualitative study was conducted with a phenomenological approach. Homogeneous sampling was performed in a final sample size of 16 subjects. The Colaizzi's phenomenological method was applied for data analysis. Three main categories were extracted from the data analysis, including the importance of nutrition in the Quran (referring to certain fruits, vegetables and foods, illustrating and venerating the heavenly ones, nutritional recommendations, revealing the healing power of honey and the effects of fruits and vegetables on physical and social health); reasons of different foods being lawful (halal) and unlawful (haram) (religious slaughter, wine, meats, consequences of consuming haram materials, general expression of halal and haram terms); and fasting (fasting and physical health, fasting and mental health). What has been mentioned in the Quran is what scientists have achieved over the time, since the Quran is governed by logic. Although we do not know the reasons for many things in the Quran, we consider it as the foundation.

Soil sampling for environmental contaminants

International Nuclear Information System (INIS)

2004-10-01

The Consultants Meeting on Sampling Strategies, Sampling and Storage of Soil for Environmental Monitoring of Contaminants was organized by the International Atomic Energy Agency to evaluate methods for soil sampling in radionuclide monitoring and heavy metal surveys for identification of punctual contamination (hot particles) in large area surveys and screening experiments. A group of experts was invited by the IAEA to discuss and recommend methods for representative soil sampling for different kinds of environmental issues. The ultimate sinks for all kinds of contaminants dispersed within the natural environment through human activities are sediment and soil. Soil is a particularly difficult matrix for environmental pollution studies as it is generally composed of a multitude of geological and biological materials resulting from weathering and degradation, including particles of different sizes with varying surface and chemical properties. There are so many different soil types categorized according to their content of biological matter, from sandy soils to loam and peat soils, which make analytical characterization even more complicated. Soil sampling for environmental monitoring of pollutants, therefore, is still a matter of debate in the community of soil, environmental and analytical sciences. The scope of the consultants meeting included evaluating existing techniques with regard to their practicability, reliability and applicability to different purposes, developing strategies of representative soil sampling for cases not yet considered by current techniques and recommending validated techniques applicable to laboratories in developing Member States. This TECDOC includes a critical survey of existing approaches and their feasibility to be applied in developing countries. The report is valuable for radioanalytical laboratories in Member States. It would assist them in quality control and accreditation process

2009-09-01

Among the benefits of examining an organization's culture are the opportunity to understand the basic mechanisms of the institutional and structural procedures, to determine the need for change and to ensure the development and satisfaction of the faculty members. To determine the perceptions of faculty members of organizational culture at nursing schools in Turkey and to examine different perceptions in relation to demographic variables. The study was conducted with 180 faculty members from seven nursing schools in state universities located in different geographical regions of Turkey that granted permission for the study. All faculty members in these schools with at least 1 year of institutional experience were included in the research. No sampling was required. A demographic information form and an organizational culture scale were used as data collection materials. The organizational culture scale contains 30 items and resolves the organizational culture in three dimensions. The minimum score obtained was 1 and the maximum was 5. The mean score for faculty members' in total scale was 3.40 (SD = 0.68), while it was 3.26 (SD = 0.77) for the management style dimension, 3.39 (SD = 0.73) for the organizational commitment/relations dimension and 3.68 (SD = 0.73) for the student-oriented dimension. There was no statistical difference between the perception of organizational culture and work experience at the institution, marital status or educational status, but there were differences in age, number of years in the profession and academic titles. It was found that strong perceptions have been established in nursing schools in regard to student-oriented practices, and that groups consisting of senior academic personnel and experienced academicians are considered to be better at perceiving the importance of the organizational culture. The administrators are recommended to promote policies to enhance the participation in decision-making processes and regularly monitor

IDENTIFICATION OF MEMBERS IN THE CENTRAL AND OUTER REGIONS OF GALAXY CLUSTERS

International Nuclear Information System (INIS)

Serra, Ana Laura; Diaferio, Antonaldo

2013-01-01

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 M 200 ≥ 10 14 h –1 M ☉ extracted from a cosmological N-body simulation of a ΛCDM 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 –1 Mpc on a side at the cluster location. On average, this sample size roughly corresponds to 180 real galaxy members within 3r 200 , similar to recent redshift surveys of cluster regions. The caustic technique yields a completeness, the fraction of identified true members, f c = 0.95 ± 0.03, within 3r 200 . The contamination, the fraction of interlopers in the observed catalog of members, increases from f i =0.020 +0.046 -0.015 at r 200 to f i =0.08 +0.11 -0.05 at 3r 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 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 symmetric stacked cluster.

Leader--member exchange, differentiation, and psychological contract fulfillment: a multilevel examination.

Science.gov (United States)

Henderson, David J; Wayne, Sandy J; Shore, Lynn M; Bommer, William H; Tetrick, Lois E

2008-11-01

Prior integrations of the leader-member exchange (LMX) and psychological contract literatures have not clarified how within-group LMX differentiation influences employees' attitudes and behaviors in the employment relationship. Therefore, using a sample of 278 members and managers of 31 intact work groups at 4 manufacturing plants, the authors examined how LMX operating at the within-group level (relative LMX, or RLMX) and the group level influenced perceptions of psychological contract fulfillment and employee-level outcomes. Controlling for individual-level perceptions of LMX quality, results indicated a positive relationship between RLMX and fulfillment, which was strengthened as group-level variability in LMX quality increased. Perceptions of fulfillment mediated the relationship between RLMX and performance and sportsmanship behaviors. The importance of conceptualizing LMX as simultaneously operating at multiple levels is highlighted.

Crosscutting Development- EVA Tools and Geology Sample Acquisition

Science.gov (United States)

2011-01-01

Exploration to all destinations has at one time or another involved the acquisition and return of samples and context data. Gathered at the summit of the highest mountain, the floor of the deepest sea, or the ice of a polar surface, samples and their value (both scientific and symbolic) have been a mainstay of Earthly exploration. In manned spaceflight exploration, the gathering of samples and their contextual information has continued. With the extension of collecting activities to spaceflight destinations comes the need for geology tools and equipment uniquely designed for use by suited crew members in radically different environments from conventional field geology. Beginning with the first Apollo Lunar Surface Extravehicular Activity (EVA), EVA Geology Tools were successfully used to enable the exploration and scientific sample gathering objectives of the lunar crew members. These early designs were a step in the evolution of Field Geology equipment, and the evolution continues today. Contemporary efforts seek to build upon and extend the knowledge gained in not only the Apollo program but a wealth of terrestrial field geology methods and hardware that have continued to evolve since the last lunar surface EVA. This paper is presented with intentional focus on documenting the continuing evolution and growing body of knowledge for both engineering and science team members seeking to further the development of EVA Geology. Recent engineering development and field testing efforts of EVA Geology equipment for surface EVA applications are presented, including the 2010 Desert Research and Technology Studies (Desert RATs) field trial. An executive summary of findings will also be presented, detailing efforts recommended for exotic sample acquisition and pre-return curation development regardless of planetary or microgravity destination.

Radial velocities of very low mass stars and candidate brown dwarf members of the Hyades and Pleiades

Stauffer, John R.; Liebert, James; Giampapa, Mark; Macintosh, Bruce; Reid, Neill; Hamilton, Donald

1994-01-01

We have determined H alpha equivalent widths and radial velocities with 1 sigma accuracies of approximately 5 km s(exp -1) for approximately 20 candidate very low mass members of the Hyades and Pleiades clusters. The radial velocities for the Hyades sample suggest that nearly all of these stars are indeed highly probable members of the Hyades. The faintest stars in the Hyades sample have masses of order 0.1 solar mass. We also obtained radial velocities for four candidate very low mass members of the Pleiades and two objects that are candidate BD Pleiads. All of these stars have apparent V magnitudes fainter than the Hyades stars we observed, and the resultant radial velocity accuracy is worse. We believe that the three brighter stars are indeed likely very low mass stellar members of the Pleiades, whereas the status of the two brown dwarf candidates is uncertain. The Hyades stars we have observed and the three Pleiades very low mass stars are the lowest mass members of any open cluster whose membership has been confirmed by radial velocities and whose chromospheric activity has been measured. We see no change in chromospheric activity at the boundary where stars are expected to become fully convective (M approximately equals 0.3 solar mass) in either cluster. In the Pleiades, however, there may be a decrease in chromospheric activity for stars with (V-I)(sub K) greater than 3.5 (M less than or equal to 0.1 solar mass).

Individual characteristics are important factors influencing organizational commitment. Also, committed human resources can lead organizations to performance improvement as well as personal and organizational achievements. This research aimed to determine the association between organizational commitment and personality traits among faculty members of Ahvaz Jundishapur University of Medical Sciences. the research population of this cross-sectional study was the faculty members of Ahvaz Jundishapur University of Medical Sciences (Ahvaz, Iran). The sample size was determined to be 83. Data collection instruments were the Allen and Meyer questionnaire for organizational commitment and Neo for characteristics' features. The data were analyzed through Pearson's product-moment correlation and the independent samples t-test, ANOVA, and simple linear regression analysis (SLR) by SPSS. Continuance commitment showed a significant positive association with neuroticism, extroversion, agreeableness, and conscientiousness. Normative commitment showed a significant positive association with conscientiousness and a negative association with extroversion (p = 0.001). Openness had a positive association with affective commitment. Openness and agreeableness, among the five characteristics' features, had the most effect on organizational commitment, as indicated by simple linear regression analysis. Faculty members' characteristics showed a significant association with their organizational commitment. Determining appropriate characteristic criteria for faculty members may lead to employing committed personnel to accomplish the University's objectives and tasks.

Using the McMaster Family Assessment Device (Epstein, Baldwin, & Bishop, 1983) and incorporating the perspectives of adolescent, mother, and father, this study examined each family member's "unique perspective" or nonshared, idiosyncratic view of the family. We used a modified multitrait-multimethod confirmatory factor analysis that (a) isolated for each family member's 6 reports of family dysfunction the nonshared variance (a combination of variance idiosyncratic to the individual and measurement error) from variance shared by 1 or more family members and (b) extracted common variance across each family member's set of nonshared 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. In addition, 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. PsycINFO Database Record (c) 2012 APA, all rights reserved.

Introduction: The overwhelming effects of cancer could be catastrophic for the patients and their family members, putting them at risk of experiencing uncertainty, loss, and an interruption in life. Also, it can influence their sense of meaning, a fundamental need equated with the purpose in life. Accordingly, this study aimed to compare the meaning in life (MiL) of patients with cancer and their family members. Methods: This descriptive comparative study was conducted on 400 patients with cancer and their family members admitted to university hospitals in Tabriz and Ardebil provinces, Iran. The participants were sampled conveniently and the Life Evaluation Questionnaire (LEQ) were used for collecting data analyzed through descriptive and inferential statistics in SPSS ver. 13 Software. Results: The mean score for the MiL of the patients with cancer and their family members was 119 (16.92) and 146.2 (17.07), respectively. There was a significant difference between patients with cancer and their family members in terms of MiL. Conclusion: The MiL of patients with cancer is lower than that of their family members, which indicates the need for further attention to the psychological processes and their modification in Iranian healthcare systems.

Automated sample changers are now standard equipment for modern macromolecular crystallography synchrotron beamlines. Nevertheless, most are only compatible with a single type of sample holder and puck. Recent work aimed at reducing sample-handling efforts and crystal-alignment times at beamlines has resulted in a new generation of compact and precise sample holders for cryocrystallography: miniSPINE and NewPin [see the companion paper by Papp et al. (2017, Acta Cryst., D73, 829-840)]. With full data collection now possible within seconds at most advanced beamlines, and future fourth-generation synchrotron sources promising to extract data in a few tens of milliseconds, the time taken to mount and centre a sample is rate-limiting. In this context, a versatile and fast sample changer, FlexED8, has been developed that is compatible with the highly successful SPINE sample holder and with the miniSPINE and NewPin sample holders. Based on a six-axis industrial robot, FlexED8 is equipped with a tool changer and includes a novel open sample-storage dewar with a built-in ice-filtering system. With seven versatile puck slots, it can hold up to 112 SPINE sample holders in uni-pucks, or 252 miniSPINE or NewPin sample holders, with 36 samples per puck. Additionally, a double gripper, compatible with the SPINE sample holders and uni-pucks, allows a reduction in the sample-exchange time from 40 s, the typical time with a standard single gripper, to less than 5 s. Computer vision-based sample-transfer monitoring, sophisticated error handling and automatic error-recovery procedures ensure high reliability. The FlexED8 sample changer has been successfully tested under real conditions on a beamline.

Community coalitions have proliferated as a means of addressing a range of complex community problems. Such coalitions often consist of a small paid staff and volunteer members. The present study examines one likely contributor to coalition effectiveness: the degree of agreement on role expectations between paid staff and volunteer members. Role confusion occurs when paid staff and volunteers differ in their expectations of who is responsible for accomplishing specific tasks. Staff and volunteer members from 69 randomly selected Drug Free Coalitions in the United States as well as 21 Drug Free Coalitions in Connecticut were asked to respond to an online survey asking about 37 specific coalition tasks critical for effective coalition functioning and the degree to which paid staff and/or voluntary members should be responsible for accomplishing each. Our final sample consisted of 476 individuals from 35 coalitions. Using coalitions as the unit of analysis, we found significant differences between paid staff and volunteer coalition members on nine tasks reflecting four domains: meeting leadership and participation, (2) planning and implementation leadership, (3) publicity/media relations, and (4) logistical functions. Implications of these differences and ways that evaluators could help coalitions deal with differing role expectations were discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

  Evaluations of faculty members are widely used to identify excellent or substandard teaching performance. In order to enable such evaluations to be properly interpreted and used in faculty development, it is essential to understand the factors that influence resident doctors' (residents) evaluations of the teaching qualities of faculty members and their perceptions of faculty members as role-model specialists.   We carried out a cross-sectional survey within a longitudinal study of the System for Evaluation of Teaching Qualities (SETQ) of clinical teachers. The study sample included 889 residents and 1014 faculty members in 61 teaching programmes spanning 22 specialties in 20 hospitals in the Netherlands. Main outcome measures included residents' (i) global and (ii) specific ratings of faculty member teaching qualities, and (iii) global ratings of faculty members as role-model specialists. Statistical analysis was conducted using adjusted multivariable logistic generalised estimating equations.   In total, 690 residents (77.6%) completed 6485 evaluations of 962 faculty members, 848 (83.6%) of whom also self-evaluated. More recently certified faculty members, those who had attended a teacher training programme, and those who spent more time teaching than seeing patients or conducting research were more likely to score highly on most teaching qualities. However, faculty members who had undergone teacher training were less likely to be seen as role models (odds ratio [OR] 0.72, 95% confidence interval [CI] 0.59-0.88). In addition, faculty members were evaluated slightly higher by male than female residents on core teaching domains and overall teaching quality, but were less likely to be seen as role models by male residents (OR 0.80, 95% CI 0.67-0.97). Lastly, faculty members had higher odds of receiving top scores in specific teaching domains from residents in the first 4 years of residency and were less likely to be considered as role models by more

Full Text Available The current study aimed to determine the quality and accreditation requirements, according to the NCAAA, for the curriculum development of the departments of Special Education as perceived by faculty members. Moreover, the study aimed to determine the relationship between the faculty awareness and other factors such as, gender, academic rank, teaching experience, participation in curriculum development, attendance of workshop, and participation in program development committees. The researcher created a survey to answer the research questions. A sample of (45 faculty members was chosen randomly from three main universities: King Khalid university, Jazan University, and Najran University.  Statistical methods were used, including mean, frequencies, one sample t–test, one way ANOVA. The results indicated that the participants' awareness toward curriculum development requirements was generally very low, because of the limited number of faculty members and the newly established departments. It was recommended that quality culture should be disseminated, and moral and material support should be provided to the programs in these departments.  Keywords: Study programs, Quality, Accreditation, Special education.

Shame and guilt/self-blame as predictors of expressed emotion in family members of patients with schizophrenia

Science.gov (United States)

Wasserman, Stephanie; Weisman de Mamani, Amy; Suro, Giulia

2012-01-01

Expressed emotion (EE) is a measure of the family environment reflecting the amount of criticism and emotional over-involvement expressed by a key relative towards a family member with a disorder or impairment. Patients from high EE homes have a poorer illness prognosis than do patients from low EE homes. Despite EE's well-established predictive validity, questions remain regarding why some family members express high levels of EE attitudes while others do not. Based on indirect evidence from previous research, the current study tested whether shame and guilt/self-blame about having a relative with schizophrenia serve as predictors of EE. A sample of 72 family members of patients with schizophrenia completed the Five Minute Speech Sample to measure EE, along with questionnaires assessing self-directed emotions. In line with the hypotheses, higher levels of both shame and guilt/self-blame about having a relative with schizophrenia predicted high EE. Results of the current study elucidate the EE construct and have implications for working with families of patients with schizophrenia. PMID:22357355

Family presence during resuscitation (FPDR) has advantages for the patients' family member to be present at the bedside. However, FPDR is not regularly practiced by nurses, especially in low to middle income countries. The purpose of this study was to determine Iranian nurses' and family members' attitudes towards FPDR. In a descriptive study, data was collected from the random sample of 178 nurses and 136 family members in four hospitals located in Iran. A 27-item questionnaire was used to collect data on attitudes towards FPDR, and descriptive and correlational analyses were conducted. Of family members, particularly the women, 57.2% (n=78) felt it is their right to experience FPDR and that it has many advantages for the family; including the ability to see that everything was done and worry less. However, 62.5% (n=111) of the nurses disagreed with an adult implementation of FPDR. Nurses perceived FPDR to have many disadvantages. Family members becoming distressed and interfering with the patient which may prolong the resuscitation effort. Nurses with prior education on FPDR were more willing to implement it. FPDR was desired by the majority of family members. To meet their needs, it is important to improve Iranian nurses' views about the advantages of the implementation of FPDR. Education on FPDR is recommended to improve Iranian nurses' views about the advantages of the implementation of FPDR. Copyright © 2017 Elsevier Ltd. All rights reserved.

The radionuclide concentration in different environmental matrixes is reported in literature; however, studies of the distribution of 238 U and 232 Th decay products in plant species are sparse. In this study concentration of naturally occurring radionuclides 238 U, 234 U, 232 Th, 230 Th, 226 Ra, 228 Ra and 210 Pb was determined in sample of Peperomia pellucida and in the surrounding soil. Peperomia pellucida has a rich history of medicinal uses. The content of U and Th isotopes in the leaves, aerial parts, roots and soil was determined by alpha spectrometry after with radiochemical separation by ionic exchange resins and measurement with a silicon surface-barrier detector. The radionuclides measurement of 226 Ra, 228 Ra and 210 Pb were carried out by gross alpha and beta counting after radiochemical separation. The radionuclide activity concentrations mean in samples analyzed ranged from 4.3 to 38 Bq kg -1 for 238 U, from 42 to 129 Bq kg -1 for 234 U, from 2.1 to 38 Bq kg -1 for 230 Th, from 1.7 to 124 Bq kg -1 for 232 Th, from 8.5 to 37 Bq kg -1 for 226 Ra, from 3.2 to 46 Bq kg -1 for 228 Ra, from 39 to 93 Bq kg -1 for 210 Pb. It was also determined the percentage of radionuclides 226 Ra, 228 Ra and 210 Pb in the extraction and infusion of the drug analyzed. The arithmetical mean value recovery was from 23% to 60% in maceration and 24% to 75% in infusion. (author)

Finding Street Gang Members on Twitter

2016-01-01

Most street gang members use Twitter to intimidate others, to present outrageous images and statements to the world, and to share recent illegal activities. Their tweets may thus be useful to law enforcement agencies to discover clues about recent crimes or to anticipate ones that may occur. Finding these posts, however, requires a method to discover gang member Twitter profiles. This is a challenging task since gang members represent a very small population of the 320 million Twitter users. ...

2004-08-01

To ascertain-1) the prevalence of depression and psychosocial characteristics in alcoholics who are members of teetotal societies, and 2) the relationship between depression and psychosocial factors. A self-report questionnaire survey was conducted of 184 alcoholic members of seven teetotal societies in a prefecture in Japan. Questionnaires consisted of items on demographics, the self-rating depression scale (SDS), family environment in childhood, self-esteem, coping, and sense of coherence (SOC). 1) The mean SDS score was 31.8 points in males and 35.8 points in females. Depression level for the male sample was equivalent to that for male employees. Coping behavior characterized by escape and resignation was more prevalent in the employees. Mean scores of both self-esteem (33.3 points) and SOC (118.7 points) were lower than in general. 2) SDS was significantly related to length of time spent within a teetotal society, self-esteem, SOC, coping behavior characterized by resignation and positive approaches to problem solving. The shorter the time within the teetotal society, the lower the scores for self-esteem, SOC, and coping behavior typified by positive approaches to problem solving; and the higher the score for coping behavior characterized by resignation, the higher the SDS score. The findings of this study suggested that depression in alcoholic members of teetotal societies occurred at similar levels to that for the general population, but that self-esteem, sense of coherence, and suitable coping behaviors were reduced. It was suggested that depression in alcoholics who are members of teetotal societies may be associated with short history of membership in the group, low sense of coherence, low self-esteem, and inappropriate coping behavior.

Trace elements in coal can occur as components of either the organic constituents (macerals) or the inorganic constituents (minerals). Studies of the concentrations and distribution of the trace elements are vital to understanding the geochemical milieu in which the coal was formed and in evaluating the attempts to recover rare but technologically valuable metals. In addition, information on the trace element concentrations is important in predicting the environmental impact of burning particular coals, as many countries move toward greater utilization of coal reserves for energy production. Traditionally, the optical and the electron microscopes and more recently the electron microprobe have been used in studying the components of coal. The proton-induced X-ray emission (PIXE) microprobe offers a new complementary approach with an order of magnitude or more better minimum detection limit. We present the first measurements with a PIXE microprobe of the trace element concentrations of bituminous coal samples. Elemental analyses of the coal macerals-vitrinite, exinite, and inertinite - are discussed for three coal samples from the Eastern U.S.A., three samples from the Western U.S.A., and one sample from the Peoples Republic of China.

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.

Massachusetts Medicaid members that smoked in 2008: Characteristics associated with smoking status in 2014.

Alexis D Henry

Full Text Available The smoking rate among non-elderly Medicaid enrollees is more than double the rate for those privately insured; smoking-related conditions account for 15% of Medicaid expenditures. Under state health reform, Massachusetts Medicaid (MassHealth made tobacco cessation treatment available beginning in 2006. We used surveys conducted in 2008 and 2014 to examine changes in smoking abstinence rates among MassHealth members identified as smokers and to identify factors associated with being a former smoker. Members previously identified as smokers were surveyed by mail or phone; 2008 and 2014 samples included 3,116 and 2,971 members, respectively. Surveys collected demographic and health information, asked members whether they smoked cigarettes "every day, some days or not at all', and asked questions to assess smoking intensity among current smokers. The 2014 survey included an open ended-question asking members "what helped the most" in quitting or quit attempts. We observed a significant decrease in members reporting smoking "every/some days" of 15.5 percentage points (p < .0001 from 2008 to 2014, and a significant decrease in smokers reporting smoking "more than 10 cigarettes on days smoked" of 16.7 percentage points (p < .0001. Compared to smokers, former smokers more frequently reported health concerns, the influence of family members, and the use of e-cigarettes as helping the most in quitting. Expanded access to tobacco cessation treatment under the Affordable Care Act may have help to reduce the high smoking rates among Medicaid enrollees. Additionally, smokers' concerns about health and the influence of family and friends provide opportunities for targeted intervention and messaging about quitting.

Employment is a vital part of the postdeployment return to civilian life. This study investigated factors associated with employment-related outcomes (employment status, self-reported work performance, and self-reported work satisfaction) among National Guard members returning from Operation Enduring Freedom, Operation Iraqi Freedom, or Operation New Dawn deployments. The sample consisted of 1,151 National Guard service members who had returned from overseas deployments approximately six months earlier. Bivariate and multivariable analyses were performed to examine associations between predictors and employment-related outcome variables. Higher-risk alcohol use was associated with reduced odds of being employed as well as with lower ratings of work satisfaction, whereas psychiatric symptom load was associated with lower self-reported work performance and work satisfaction ratings. Perceived social resources were associated with higher self-reported work performance and work satisfaction, whereas better physical functioning was associated with better self-reported work performance. Policy makers and clinicians may need to consider and assess alcohol use among unemployed National Guard members. They may also need to consider psychiatric symptom load and physical functioning among employed service members who perceive poor work performance and have low work satisfaction. Further research is needed on causal links between these predictors and employment outcomes.

IAEA sends out samples of uranium ore

Full text: Governments and organizations interested in developing uranium resources will be assisted by a new service, now being inaugurated by the Agency's laboratories, for the distribution of reference samples of uranium ores. This is an addition to the service which began at Seibersdorf in January 1962 for the distribution of calibrated radionuclides, and which has met with a steadily increasing demand. * Uranium deposits consisting of ores with a uranium content in the range 0.5 - 0.05 per cent occur in a number of countries, including developing countries and can present considerable analytical difficulties. In 1962 the Agency asked Member States whether they would be interested in receiving reference samples of uranium ores to assist them in checking their methods of chemical analysis. The response encouraged the Agency to proceed. There is a multiplicity of types of uranium ores and, initially, three of the most commonly occurring have been selected - torbernite, uraninite and carnotite. Member States have provided the laboratory with supplies of these three types of ore. In order to determine the uranium content, samples are sent to leading laboratories throughout the world, so as to arrive at the most accurate values possible. This work has proved to be useful to the laboratories themselves ; in searching for reasons for discrepancies between the different collaborating laboratories, they enlarge their own knowledge and improve their methods. The reference samples are sent out in the form of fine powder, and are available to atomic energy commissions, research laboratories or mining companies. The requesting laboratory, having worked out the analytical process best suited to its needs, is then able to check its results by analysing an IAEA reference sample of known uranium content. By the end of 1966, reference samples will be available of the three ores mentioned, and later also of pure uranium oxide and of uranium oxide containing trace impurities, the

Burnout in Female Faculty Members.

Cassidy-Vu, Lisa; Beck, Keli; Moore, Justin B

2017-04-01

Despite approximately equal numbers of male and female medical school graduates, women are entering academic medicine at a lower rate than their male colleagues. Of those who do assume a faculty position, female faculty members report higher levels of burnout, often attributable to gender-specific difficulties in clinical expectations and maintenance of work-life balance. Many of these struggles are attributable to issues that are amenable to supportive policies, but these policies are inconsistent in their availability and practice. This commentary presents evidence for inconsistencies in the day-to-day experience of female faculty members, and proposes solutions for the mitigation of the challenges experienced more often by female faculty members with the goal of diversifying and strengthening academic medicine.

Apparatus for sampling hazardous media

International Nuclear Information System (INIS)

Gardner, J.F.; Showalter, T.W.

1984-01-01

An apparatus for sampling a hazardous medium, such as radioactive or chemical waste, selectively collects a predetermined quantity of the medium in a recess of an end-over-end rotatable valving member. This collected quantity is deposited in a receiving receptacle located in a cavity while the receiving receptacle is in a sealed relationship with a recess to prevent dusting of the sampled media outside the receiving receptacle. The receiving receptacle is removably fitted within a vehicle body which is, in turn, slidably movable upon a track within a transport tube. The receiving receptacle is transported in the vehicle body from its sample receiving position within a container for the hazardous medium to a sample retrieval position outside the medium container. The receiving receptacle may then be removed from the vehicle body, capped and taken to a laboratory for chemical analysis. (author)

Little is known about the differences between gang members and gang affiliates-or those individuals who associate with gangs but are not gang members. Even less is known about how these groups compare with other violent populations. This study examined how gang members, gang affiliates, and violent men compare on mental health symptoms and traumatic experiences. Data included a sample of 1,539 adult males, aged 19 to 34 years, taken from an earlier survey conducted in the United Kingdom. Participants provided informed consent before completing questionnaires and were paid £5 for participation. Logistic regression analyses were conducted to compare participants' symptoms of psychiatric morbidity and traumatic event exposure. Findings showed that, compared to violent men and gang affiliates, gang members had experienced more severe violence, sexual assaults, and suffered more serious/life-threatening injuries. Compared to violent men, gang members and gang affiliates had made more suicide attempts; had self-harmed more frequently; and had experienced more domestic violence, violence at work, homelessness, stalking, and bankruptcy. Findings further showed a decreasing gradient from gang members to gang affiliates to violent men in symptom levels of anxiety, antisocial personality disorder, pathological gambling, stalking others, and drug and/or alcohol dependence. Depression symptoms were similar across groups. The identified relationship between gang membership, affiliation, and adverse mental health indicates that mental health in gang membership deserves more research attention. Findings also indicate that criminal justice strategies need to consider gang members' mental health more fully, if gang membership is to be appropriately addressed and reduced.

Full Text Available The efficacy of decoction in extracting mycobactericidal compounds from Flourensia cernua (Hojasé leaves and fractionation with solvents having ascending polarity was compared with that of (i ethanol extraction by still maceration, extraction with a Soxhlet device, shake-assisted maceration, or ultrasound-assisted maceration, followed by fractionation with n-hexane, ethyl acetate, and n-butanol; (ii sequential extraction with n-hexane, ethyl acetate, and n-butanol, by still maceration, using a Soxhlet device, shake-assisted maceration, or ultrasound-assisted maceration. The in vitro mycobactericidal activity of each preparation was measured against drug-sensitive (SMtb and drug-resistant (RMtb Mycobacterium tuberculosis strains. The results of which were expressed as absolute mycobactericidal activity (AMA. These data were normalized to the ΣAMA of the decoction fraction set. Although decoction was inactive, the anti-RMtb normalized ΣAMA (NAMA of its fractions was comparable with the anti-RMtb NAMA of the still maceration extracts and significantly higher than the anti-SMtb and anti-RMtb NAMAs of every other ethanol extract and serial extract and fraction. Hexane extracted, from decoction, material having 55.17% and 92.62% of antituberculosis activity against SMtb and RMtb, respectively. Although the mycobactericidal activity of decoction is undetectable; its efficacy in extracting F. cernua active metabolites against M. tuberculosis is substantially greater than almost all pharmacognostic methods.

Worldwide, caregivers find caring for children with Autism Spectrum Disorder (ASD) challenging. Family members must manage many aspects of care giving, which is demanding, overwhelming, and can affect the family members' mental health. However learning how to be resilient may help family members overcome the stress and burden associated with caring for a person with ASD. A search was completed in Medline, PsycINFO, Proquest, Web of Science, and CINAHL using the key words "autism," "caregivers," "mothers," and "fathers," alone and in combination. Inclusion criteria were English language articles reporting studies with samples of children with ASD, as distinct from children with other intellectual or developmental disabilities. Fifty-eight articles that met these inclusion criteria were summarized and, from those, the authors selected 22 articles that included indicators of resilience. This integrative review highlights current research on resilience in adult family members of persons with ASD. Indicators of resilience, risk factors, protective factors, and outcomes of resilience were identified. The review indicates that parents of children with ASD who possess indicators of resilience are better able to manage the adversity associated with caring for children with ASD. Thus, enhancing resilience among family members of persons with autism may be beneficial to both the caregivers and care recipients.

Integrating Implicit Leadership Theories, Leader-Member Exchange, Self-Efficacy, and Attachment Theory to Predict Job Performance.

Science.gov (United States)

Khorakian, Alireza; Sharifirad, Mohammad Sadegh

2018-01-01

The impact of implicit leadership theories on performance and the mechanism linking them have received insufficient theoretical and research attention. Drawing on Bandura's social cognitive theory, the present study contributes theory through examining the assertion that higher congruence between followers' implicit leadership theory and the characteristics of supervisors enhance job performance through higher quality of leader-member exchange and self-efficacy. Moreover, in the proposed model, attachment insecurity was considered as the antecedent of the congruence and leader-member exchange in addition to the moderator of the relationship between them. Capitalizing upon Structural Equation Modeling (SEM), this study tested the model in a field study using a sample of employees in knowledge-oriented firms in Iran. The results suggest that the congruence between followers' implicit leadership theory and the characteristics of supervisors does not directly impact performance and leader-member exchange and self-efficacy are the full mediators. The results also showed that attachment insecurity is the predictor of neither the congruence nor the leader-member exchange. Additionally, attachment insecurity moderates the relationship between these two variables in a way that when attachment insecurity is high, the congruence has more positive impact on leader-member exchange.

The involvement of family members in psychiatric care is important for the recovery of persons with psychotic disorders and subsequently reduces the burden on the family. Earlier qualitative studies suggest that the participation of family members can be limited by how they experience the professionals' approach, which suggests a connection to the concept of alienation. Thus, the aim of this study was in a national sample investigate family members' experiences of the psychiatric health care professionals' approach. Data were collected by the Family Involvement and Alienation Questionnaire. The median level and quartiles were used to describe the distributions and data were analysed with non-parametric statistical methods. Seventy family members of persons receiving psychiatric care participated in the study. The results indicate that a majority of the participants respond that they have experiencing a negative approach from the professionals, indicating lack of confirmation and cooperation. The results also indicate that a majority of the participants felt powerlessness and social isolation in the care being provided, indicating feelings of alienation. A significant but weak association was found between the family members' experiences of the professionals' approach and their feelings of alienation.

Faculty development is needed that will influence clinical teachers to better enable them to transmit humanistic values to their learners and colleagues. We sought to understand the processes whereby reflective learning influenced professional growth in a convenience sample of young faculty members. We analyzed appreciative inquiry narratives written over 4 years using the constant comparative method to identify major underlying themes and develop hypotheses concerning how reflective learning influenced participants in the faculty development program. Six of the participants and the facilitator were participant observers in the qualitative analysis. Group support, validation, and cohesion led to adoption of common values that informed the professional development of the participants over 4 years of the study. Common values influenced the group members as they progressed in their careers. Faculty development programs that focus on humanism and reflective learning can facilitate the growth of young faculty members by influencing their values and attitudes at crucial phases of their careers.

Migration processes in SCO member states

Directory of Open Access Journals (Sweden)

Valentina Sergeevna Antonyuk

2012-12-01

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.

Rockstuhl, Thomas; Dulebohn, James H; Ang, Soon; Shore, Lynn M

2012-11-01

This study extends leader-member exchange (LMX) research by meta-analyzing the role of national culture in moderating relationships between LMX and its correlates. Results based on 282 independent samples (N = 68,587) from 23 countries and controlling for extreme response style differences indicate that (a) relationships of LMX with organizational citizenship behavior, justice perceptions, job satisfaction, turnover intentions, and leader trust are stronger in horizontal-individualistic (e.g., Western) contexts than in vertical-collectivistic (e.g., Asian) contexts; and (b) national culture does not affect relationships of LMX with task performance, organizational commitment, and transformational leadership. These findings highlight that although members are universally sensitive to how their leaders treat them, members' responses in Asian contexts may also be influenced by collective interests and role-based obligations.

Bowen, Gary L; Jensen, Todd M; Martin, James A; Mancini, Jay A

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. © Society for Community Research and Action 2016.

Delinquency Among Members of Hong Kong Youth Street Gangs: The Role of the Organizational Structures of Gangs and Triad Affiliations.

Chui, Wing Hong; Khiatani, Paul Vinod

2018-07-01

This study explores the importance of organizational structures and formal affiliations with the Hong Kong triads to delinquency among youth street gang members in Hong Kong. More specifically, this study examines the relative importance of the number of organizational structures and triad affiliation to patterns of delinquency in a sample of active members of youth street gangs ( N = 201). With the aid of outreach social workers, a convenience sampling method was used to recruit a gender-balanced sample of at-risk youths. Logistic regression analysis of the survey data that was gathered indicated that formal affiliation to Hong Kong triads and the presence of organizational structures significantly increased the odds of delinquency (independently of each other). Suggestions for future research on gang membership and delinquency, with particular reference to the Asian context, are provided.

Full Text Available Introduction: The research considers safety climate in a warehouse and wants to analyze the Leader–Member Exchange (LMX role in respect to safety performance. Griffin and Neal’s safety model was adopted and Leader-Member Exchange was inserted as moderator in the relationships between safety climate and proximal antecedents (motivation and knowledge of safety performance constructs (compliance and participation.Materials and Methods: Survey data were collected from a sample of 133 full-time employees in an Italian warehouse. The statistical framework of Hayes (2013 was adopted for moderated mediation analysis.Results: Proximal antecedents partially mediated the relationship between Safety climate and safety participation, but not safety compliance. Moreover, the results from the moderation analysis showed that the Leader–Member Exchange moderated the influence of safety climate on proximal antecedents and the mediation exist only at the higher level of LMX.Conclusion: The study shows that the different aspects of leadership processes interact in explaining individual proficiency in safety practices.Practical Implications: Organizations as warehouses should improve the quality of the relationship between a leader and a subordinate based upon the dimensions of respect, trust, and obligation for high level of safety performance.

Performance of student software development teams: the influence of personality and identifying as team members

Monaghan, Conal; Bizumic, Boris; Reynolds, Katherine; Smithson, Michael; Johns-Boast, Lynette; van Rooy, Dirk

2015-01-01

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.

What questions do board members in public service organizations ask about executive compensation?

Directory of Open Access Journals (Sweden)

Chris Bart

2014-11-01

Full Text Available The purpose of this study is to investigate the governance questions that board members in public service organizations ask as they go about fulfilling their responsibilities for the oversight of executive compensation. The research uses 24 of the questions – as proposed by the Canadian Institute of Chartered Accountants - that directors should ask about executive compensation and investigates both their usage and perceived importance by board members. The study is based on a usable sample of 47 board members from public service organizations who were attending a Canadian director training program. The research finds that, insofar as public service organizations are concerned, not all of the recommended executive compensation governance questions were asked with the same frequency nor were they considered equally important. Additionally, the relationship between a question’s usage frequency and its perceived importance was not perfect. However, there appears to be a significantly positive relationship among the number of executive compensation governance questions asked and selected elements of a board’s governance structure.

Spears, Richard K.

1995-01-01

Matrix-fiber composite materials developed for structural members occasionally exposed to hot, corrosive gases. Integral ceramic fabric surface layer essential for resistance to flames and chemicals. Endures high temperature, impedes flame from penetrating to interior, inhibits diffusion of oxygen to interior where it degrades matrix resin, resists attack by chemicals, helps resist erosion, and provides additional strength. In original intended application, composite members replace steel structural members of rocket-launching structures that deteriorate under combined influences of atmosphere, spilled propellants, and rocket exhaust. Composites also attractive for other applications in which corrosion- and fire-resistant structural members needed.

Families of miocene monterey crude oil, seep, and tarball samples, coastal California

Peters, K.E.; Hostettler, F.D.; Lorenson, T.D.; Rosenbauer, R.J.

2008-01-01

Biomarker and stable carbon isotope ratios were used to infer the age, lithology, organic matter input, and depositional environment of the source rocks for 388 samples of produced crude oil, seep oil, and tarballs to better assess their origins and distributions in coastal California. These samples were used to construct a chemometric (multivariate statistical) decision tree to classify 288 additional samples. The results identify three tribes of 13C-rich oil samples inferred to originate from thermally mature equivalents of the clayey-siliceous, carbonaceous marl and lower calcareous-siliceous members of the Monterey Formation at Naples Beach near Santa Barbara. An attempt to correlate these families to rock extracts from these members in the nearby COST (continental offshore stratigraphic test) (OCS-Cal 78-164) well failed, at least in part because the rocks are thermally immature. Geochemical similarities among the oil tribes and their widespread distribution support the prograding margin model or the banktop-slope-basin model instead of the ridge-and-basin model for the deposition of the Monterey Formation. Tribe 1 contains four oil families having geochemical traits of clay-rich marine shale source rock deposited under suboxic conditions with substantial higher plant input. Tribe 2 contains four oil families with traits intermediate between tribes 1 and 3, except for abundant 28,30-bisnorhopane, indicating suboxic to anoxic marine marl source rock with hemipelagic input. Tribe 3 contains five oil families with traits of distal marine carbonate source rock deposited under anoxic conditions with pelagic but little or no higher plant input. Tribes 1 and 2 occur mainly south of Point Conception in paleogeographic settings where deep burial of the Monterey source rock favored petroleum generation from all three members or their equivalents. In this area, oil from the clayey-siliceous and carbonaceous marl members (tribes 1 and 2) may overwhelm that from the lower

Susarla, Harlyn K; Dhar, Vineet; Karimbux, Nadeem Y; Tinanoff, Norman

2017-04-01

The aim of this cross-sectional study was to assess the relationship between quantitative measures of research productivity and academic rank for full-time pediatric dentistry faculty members in accredited U.S. and Canadian residency programs. For each pediatric dentist in the study group, academic rank and bibliometric factors derived from publicly available databases were recorded. Academic ranks were lecturer/instructor, assistant professor, associate professor, and professor. Bibliometric factors were mean total number of publications, mean total number of citations, maximum number of citations for a single work, and h-index (a measure of the impact of publications, determined by total number of publications h that had at least h citations each). The study sample was comprised of 267 pediatric dentists: 4% were lecturers/instructors, 44% were assistant professors, 30% were associate professors, and 22% were professors. The mean number of publications for the sample was 15.4±27.8. The mean number of citations was 218.4±482.0. The mean h-index was 4.9±6.6. The h-index was strongly correlated with academic rank (r=0.60, p=0.001). For this sample, an h-index of ≥3 was identified as a threshold for promotion to associate professor, and an h-index of ≥6 was identified as a threshold for promotion to professor. The h-index was strongly correlated with the academic rank of these pediatric dental faculty members, suggesting that this index may be considered a measure for promotion, along with a faculty member's quality and quantity of research, teaching, service, and clinical activities.

Static Members of Classes in C#

Full Text Available The C# language is object-oriented, which is why the declared member data must be part of a class. Thus, there is no possibility to declare certain variables that can be accessed from anywhere within the application, as it happens, for example, with global variables at the C language level. Making this work in C# is possible through static members of the class. Declaring a class implies defining some of its member data that later receive values when creating each object. A static member of the class can be interpreted as belonging only to the class, not to the objects subsequently created, which means that for the non-static data, there are as many children as there were objects created, while for the static ones there is only one copy, regardless of the number of created objects. In this regard, this paper presents the main aspects that characterize these abstract concepts of object oriented programming in general and C# language in particular, detailing how to develop an application that includes both static and non-static members. At the same time, particularities in the mirror for the two types of data, restrictions on use and potential limitations are presented.

We found that family member satisfaction levels were affected by gender and occupation, the existence of someone supporting the care, and possession of sufficient information about the patient.

Soil sampling intercomparison exercise by selected laboratories of the ALMERA Network

International Nuclear Information System (INIS)

2009-01-01

The IAEA's Seibersdorf Laboratories in Austria have the programmatic responsibility to provide assistance to Member State laboratories in maintaining and improving the reliability of analytical measurement results, both in radionuclide and trace element determinations. This is accomplished through the provision of reference materials of terrestrial origin, validated analytical procedures, training in the implementation of internal quality control, and through the evaluation of measurement performance by the organization of worldwide and regional interlaboratory comparison exercises. The IAEA is mandated to support global radionuclide measurement systems related to accidental or intentional releases of radioactivity in the environment. To fulfil this obligation and ensure a reliable, worldwide, rapid and consistent response, the IAEA coordinates an international network of analytical laboratories for the measurement of environmental radioactivity (ALMERA). The network was established by the IAEA in 1995 and makes available to Member States a world-wide network of analytical laboratories capable of providing reliable and timely analysis of environmental samples in the event of an accidental or intentional release of radioactivity. A primary requirement for the ALMERA members is participation in the IAEA interlaboratory comparison exercises, which are specifically organized for ALMERA on a regular basis. These exercises are designed to monitor and demonstrate the performance and analytical capabilities of the network members, and to identify gaps and problem areas where further development is needed. In this framework, the IAEA organized a soil sampling intercomparison exercise (IAEA/SIE/01) for selected laboratories of the ALMERA network. The main objective of this exercise was to compare soil sampling procedures used by different participating laboratories. The performance evaluation results of the interlaboratory comparison exercises performed in the framework of

h-index is useful for quantifying scholarly activity in medicine, but this statistic has not been extensively applied as a measure of productivity in anaesthesia. We conducted a bibliometric analysis of h-index in editorial board members and tested the hypothesis that editorial board members of anaesthesia journals with higher impact factors (IFs) have higher h-indices. Ten of 19 journals with 2009 IF>1 were randomly chosen from Journal Citation Reports(®). Board members were identified using each journal's website. Publications, citations, citations per publication, and h-index for each member were obtained using Scopus(®). Four hundred and twenty-three individuals filled 481 anaesthesia editorial board positions. The median h-index of all editorial board members was 14. Board members published 75 papers (median) with 1006 citations and 13 citations per publication. Members serving on journals with IF greater than median had significantly (Pcitations, and citations per publication than those at journals with IF less than median. A significant correlation between the median h-index of a journal's editorial board members and its IF (h-index=3.01×IF+6.85; r( 2)=0.452; P=0.033) was observed for the 10 journals examined. Board members of subspeciality-specific journals had bibliometric indices that were less than those at general journals. The h-index was greater in individuals serving more than one journal. European editorial board members had higher h-index values than their American colleagues. The results suggest that editorial board members of anaesthesia journals with higher IFs have higher h-indices.

Youth Gang Members: Psychiatric Disorders and Substance Use

Directory of Open Access Journals (Sweden)

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.

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

Members of the Candidate Phyla Radiation are functionally differentiated by carbon and nitrogen cycling capabilities.

The Candidate Phyla Radiation (CPR) is a recently described expansion of the tree of life that represents more than 15% of all bacterial diversity and putatively contains over 70 different phyla. Despite this broad phylogenetic variation, these microorganisms often feature limited functional diversity, with members generally characterized as obligate fermenters. Additionally, much of the data describing CPR phyla has been generated from a limited number of environments, constraining our knowledge of their functional roles and biogeographical distribution. To better understand subsurface CPR microorganisms, we sampled four groundwater wells over two years across three Ohio counties. Samples were analyzed using 16S rRNA gene amplicon and shotgun metagenomic sequencing. Amplicon results indicated that CPR members comprised 2-20% of the microbial communities, with relative abundances stable through time in Athens and Greene county samples but dynamic in Licking county groundwater. Shotgun metagenomic analyses generated 71 putative CPR genomes, representing roughly 32 known phyla and potentially two new phyla, Candidatus Brownbacteria and Candidatus Hugbacteria. While these genomes largely mirrored typical CPR metabolism, some features were previously uncharacterized. For instance, a nirK-encoded nitrite reductase was found in four of our Parcubacteria genomes and multiple CPR genomes from other studies, indicating a possibly undescribed role for these microorganisms in denitrification. Additionally, glycoside hydrolase (GH) family profiles for our genomes and over 2000 other CPR genomes were analyzed to characterize their carbon processing potential. Although common trends were present throughout the radiation, differences highlighted mechanisms that may allow microorganisms across the CPR to occupy various subsurface niches. For example, members of the Microgenomates superphylum appear to potentially degrade a wider range of carbon substrates than other CPR phyla. The

Science, new technology, patient care, dental reimbursement and government regulations all affect today's dental practitioners. To find out more about how such challenges may affect current private practitioners, the American Dental Association conducted the 2000 Membership Needs and Opinions Survey. A questionnaire was sent to 6,310 ADA members in January 2000 with follow-up mailings in February, March and April 2000. Data collection was completed in July 2000. The survey included questions on critical professional issues, and on perceptions of the ADA and ADA priorities. A total of 3,558 completed surveys were received for an adjusted response rate of 59.5 percent. Members rated the identified issues' level of importance to them. The top three issues included "maintaining my ability to recommend the treatment option I feel is most appropriate for my patients," "receiving fair reimbursement for the dental services I provide," and "protecting myself, my staff and my patients from communicable diseases." New dentists found other items to be more significant to them compared with members overall. Although ADA members as a whole had similar views on critical issues facing dentistry and ADA priorities, there were significant differences regarding some issues. New dentists were far more concerned about securing funds for their practice and paying off debt than were all ADA members. Minority dentists expressed greater levels of concern about certain issues than did all ADA members. When planning and implementing ADA activities, the Association should continue to take into account members' relative rankings of professional issues and note issues of special interest to selected membership subgroups.

We present chemical abundance measurements for seven stars with metallicities ranging from Fe/H] = ‑3.3 to [Fe/H] = ‑2.4 in the Tucana II ultra-faint dwarf galaxy (UFD), based on high-resolution spectra obtained with the MIKE spectrograph on the 6.5 m Magellan-Clay Telescope. For three stars, we present detailed chemical abundances for the first time. Of those, two stars are newly discovered members of Tucana II and were selected as probable members from deep narrowband photometry of the Tucana II UFD taken with the SkyMapper telescope. This result demonstrates the potential for photometrically identifying members of dwarf galaxy systems based on chemical composition. One new star was selected from the membership catalog of Walker et al. The other four stars in our sample have been reanalyzed, following additional observations. Overall, six stars have chemical abundances that are characteristic of the UFD stellar population. The seventh star shows chemical abundances that are discrepant from the other Tucana II members and an atypical, higher strontium abundance than what is expected for typical UFD stars. While unlikely, its strontium abundance raises the possibility that it may be a foreground metal-poor halo star with the same systemic velocity as Tucana II. If we were to exclude this star, Tucana II would satisfy the criteria to be a surviving first galaxy. Otherwise, this star implies that Tucana II has likely experienced somewhat extended chemical evolution. This paper includes data gathered with the 6.5 m Magellan Telescopes located at Las Campanas Observatory, Chile.

Mastalerz, Maria; Drobniak, A.; Strapoc, D.; Solano-Acosta, W.; Rupp, J.

2008-01-01

The Seelyville Coal Member of the Linton Formation (Pennsylvanian) in Indiana was studied to: 1) understand variations in pore characteristics within a coal seam at a single location and compare these variations with changes occurring between the same coal at different locations, 2) elaborate on the influence of mineral-matter and maceral composition on mesopore and micropore characteristics, and 3) discuss implications of these variations for coal bed gas content. The coal is high volatile bituminous rank with R0 ranging from 0.57% to 0.60%. BET specific surface areas (determined by nitrogen adsorption) of the coals samples studied range from 1.8 to 22.9??m2/g, BJH adsorption mesopore volumes from 0.0041 to 0.0339??cm3/g, and micropore volumes (determined by carbon dioxide adsorption) from 0.0315 to 0.0540??cm3/g. The coals that had the largest specific surface areas and largest mesopore volumes occur at the shallowest depths, whereas the smallest values for these two parameters occur in the deepest coals. Micropore volumes, in contrast, are not depth-dependent. In the coal samples examined for this study, mineral-matter content influenced both specific surface area as well as mesopore and micropore volumes. It is especially clear in the case of micropores, where an increase in mineral-matter content parallels the decrease of micropore volume of the coal. No obvious relationships were observed between the total vitrinite content and pore characteristics but, after splitting vitrinite into individual macerals, we see that collotelinite influences both meso- and micropore volume positively, whereas collodetrinite contributes to the reduction of mesopore and micropore volumes. There are large variations in gas content within a single coal at a single location. Because of this variability, the entire thickness of the coal must be desorbed in order to determine gas content reliably and to accurately calculate the level of gas saturation. ?? 2008 Elsevier B.V.

Identifying and assessing uncertainty in hydrological pathways: a novel approach to end member mixing in a Scottish agricultural catchment

Science.gov (United States)

Soulsby, C.; Petry, J.; Brewer, M. J.; Dunn, S. M.; Ott, B.; Malcolm, I. A.

2003-04-01

A hydrograph separation based upon end member mixing was carried out to assess the relative importance of the hydrological pathways providing the main sources of runoff during five storm events in a 14.5 km 2 agricultural catchment in north east Scotland. The method utilised event specific end member chemistries to differentiate three catchment-scale hydrological pathways on the basis of observed Si and NO 3-N concentrations in sampled source waters. These were overland flow (OF) (low Si and intermediate NO 3-N); subsurface storm flow (high Si and high NO 3-N) and groundwater flow (high Si and intermediate NO 3-N). The hydrograph separation explicitly accounted for uncertainty in the spatial and temporal variation in end member chemistry using Bayesian statistical methods which assumed that each end member arose from a bivariate normal distribution whose mean vectors and co-variance matrices could be estimated. Markov Chain-Monte Carlo methods were used to model the average and 95 percentile maximum and minimum contributions that each end member made to stream water samples during storm events. Although there is large uncertainty over the contributions of each end member to specific events, the analysis produced hydrograph separations that were broadly believable on the basis of hydrometric observations in the catchment. Moreover, by using event specific end member compositions, the method appeared sensitive to the unique combination of event characteristics, antecedent conditions and seasonality in terms of producing feasible separations for very different events. It is concluded that OF generally dominates the storm peak and provides the main flow path by which P is transferred to stream channels during storm events, whilst subsurface storm flows usually dominate the storm hydrograph volumetrically and route NO 3-rich soil water into streams. Consequently, nutrient enrichment in such streams is largely mediated by event-based hydrological flow paths, a finding

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.

Analyses and characterization of fossil carbonaceous materials for silicon production

Energy Technology Data Exchange (ETDEWEB)

Myrvaagnes, Viktor

2008-01-15

Production of high silicon alloys is carried out in submerged arc furnaces by reduction of silicon bearing oxides (typically quartz) with carbon materials. Carbonaceous materials like coal, coke, charcoal and woodchips are commonly used as reduction materials in the process. Primarily based on historical prices of charcoal compared to fossil reduction materials, the Norwegian Ferroalloy Industry has mostly been using coal and coke (char) as the source of carbon. From a process point of view, the most important role of the carbonaceous material is to react with SiO gas to produce SiC. The ability of the reduction materials to react with SiO gas can be measured and the value is recognized as the reactivity of the carbon source. Reactivity is one of the most important parameters in the smelting process and is commonly acknowledged to strongly affect both productivity and specific energy consumption. The main objectives of this work has been to establish methods to characterize the material properties of fossil carbonaceous reduction materials used in the silicon process and to evaluated how these properties affect the reactivity towards SiO gas. In order to accomplish these objectives, three run of mine (ROM) single seam coals which are particularly well suited for ferroalloy production were selected. Two Carboniferous coals from USA (Blue Gem) and Poland (Staszic) with similar rank, but significantly different composition as well as a Permian coal from Australia (Peak Downs) have been characterized by chemical- and petrographical methods. Blue Gem is a homogeneous coal, low in mineral inclusions and macerals of the inertinite group and determined to have a random vitrinite reflectance of 0.71 %. Staszic has a similar reflectance of vitrinite (0.72 %), but is determined to be a very inhomogeneous coal with both inertinite macerals and minerals embedded in the vitrinite matrix. Peak Downs has a random reflectance of vitrinite of 1.32 % and is hence the coal sample of

The peel of yellow passion fruit is as an agro-industrial waste of great environmental impact, representing more than 50% of the total weight of the fruit. For this reason, and also considering its importance as a source of functional components such as pectin, this organic waste is increasingly attracting the attention of researchers. The aim of this study was to investigate the physico-chemical composition and physical properties of this material, which may be of interest to the food industry. We obtained two samples of passion fruit peel flour applying different processes: flour without treatment (FWOT) and flour with treatment by maceration (FWT). It was found that the flour samples contain, respectively, 372.4 g kg -1 and 246.7 kg -1 of soluble fiber and, according to the FTIR analysis, this material corresponds to high and low methoxyl pectins, respectively. The flour obtained by maceration (FWT) offers greater benefits for industrial use, with 60% fewer tannins and greater thermal stability. In addition, this sample does not reabsorb moisture as easily, although FWOT also shows potential for use in dietary products. Considering the pseudoplastic properties of the flours, the application of both samples could be expanded to many industrial sectors. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

Despite Al-Anon's widespread availability and use, knowledge is lacking about the drinkers in attendees' lives. We filled this gap by describing and comparing Al-Anon newcomers' and members' reports about their "main drinker" (main person prompting initial attendance). Al-Anon's World Service Office mailed a random sample of groups, yielding completed surveys from newcomers (N = 362) and stable members (N = 265). Newcomers' and members' drinkers generally were comparable. They had known their drinker for an average of 22 years and been concerned about his or her's drinking for 9 years; about 50% had daily contact with the drinker. Most reported negative relationship aspects (drinker gets on your nerves; you disagree about important things). Newcomers had more concern about the drinker's alcohol use than members did, and were more likely to report their drinkers' driving under the influence. Drinkers' most frequent problem due to drinking was family arguments, and most common source of help was 12-step groups, with lower rates among drinkers of newcomers. Concerns spurring initial Al-Anon attendance were the drinker's poor quality of life, relationships, and psychological status; goals for initial attendance reflected these concerns. The drinker's alcohol use was of less concern in prompting initial Al-Anon attendance, and, accordingly, the drinker's reduced drinking was a less frequently endorsed goal of attendance. Family treatments for substance use problems might expand interventions and outcome domains beyond abstinence and relationship satisfaction to include the drinker's quality of life and psychological symptoms and in turn relieve concerns of family members. © American Academy of Addiction Psychiatry.

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.

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.

Genome-Resolved Metagenomic Analysis Reveals Roles for Candidate Phyla and Other Microbial Community Members in Biogeochemical Transformations in Oil Reservoirs

Directory of Open Access Journals (Sweden)

Ping Hu

2016-01-01

Full Text Available Oil reservoirs are major sites of methane production and carbon turnover, processes with significant impacts on energy resources and global biogeochemical cycles. We applied a cultivation-independent genomic approach to define microbial community membership and predict roles for specific organisms in biogeochemical transformations in Alaska North Slope oil fields. Produced water samples were collected from six locations between 1,128 m (24 to 27°C and 2,743 m (80 to 83°C below the surface. Microbial community complexity decreased with increasing temperature, and the potential to degrade hydrocarbon compounds was most prevalent in the lower-temperature reservoirs. Sulfate availability, rather than sulfate reduction potential, seems to be the limiting factor for sulfide production in some of the reservoirs under investigation. Most microorganisms in the intermediate- and higher-temperature samples were related to previously studied methanogenic and nonmethanogenic archaea and thermophilic bacteria, but one candidate phylum bacterium, a member of the Acetothermia (OP1, was present in Kuparuk sample K3. The greatest numbers of candidate phyla were recovered from the mesothermic reservoir samples SB1 and SB2. We reconstructed a nearly complete genome for an organism from the candidate phylum Parcubacteria (OD1 that was abundant in sample SB1. Consistent with prior findings for members of this lineage, the OD1 genome is small, and metabolic predictions support an obligately anaerobic, fermentation-based lifestyle. At moderate abundance in samples SB1 and SB2 were members of bacteria from other candidate phyla, including Microgenomates (OP11, Atribacteria (OP9, candidate phyla TA06 and WS6, and Marinimicrobia (SAR406. The results presented here elucidate potential roles of organisms in oil reservoir biological processes.

2006-12-01

The objective of this work was to investigate the extraction of Ilex paraguariensis leaves by means of three extraction techniques: pressurized liquid extraction (PLE, also called accelerated solvent extraction--ASE), maceration, and sonication. Samples of mate tea leaves were collected from an experiment conducted under agronomic control at Indfistria e Comércio de Erva-Mate Barão LTDA, Brazil. Six solvents with increasing polarities (n-hexane, toluene, dichloromethane, ethyl acetate, acetone, and methanol) were used in this investigation. Chemical analysis of the extracts was performed by GC coupled with a mass spectrometer detector. The identification and quantification were accomplished by coinjections of certified standards. The results showed that no significant differences in the qualities of the extracts were noticed regarding the extraction methods. On the other hand, the PLE technique was found to be more effective for the extractions of caffeine, phytol, palmitic, and stearic acid. The use of PLE led to a significant decrease in the total extraction time, amount of solvent consumption, and manipulation of samples compared to maceration and ultrasound-assisted extraction methods.

The Nexus between FDI and Growth in the SAARC Member Countries

Directory of Open Access Journals (Sweden)

Sangjoon Jun

2015-03-01

Full Text Available This paper examines the effects of foreign direct investment (FDI on South Asian economies' output growth, utilizing recent panel cointegration testing and estimation techniques. Annual panel data on eight SAARC (South Asian Association for Regional Cooperation member countries' macroeconomic variables over the period 1960- 2013 are employed in empirical analysis. Using various heterogeneous panel cointegration and panel causality tests, a bi-directional relationship between FDI and growth is found. We find evidence for both FDI-led growth and growth-induced FDI hypotheses for the South Asian economies over the sample period. Individual member countries exhibit heterogeneity in terms of the direction or existence of causality subject to their idiosyncratic economic conditions. Among various regressors, FDI, financial development, human capital, and government consumption show the most significant positive effects on output growth. As determinants of FDI, GDP, financial development, human capital, and government consumption are found significant in the region. The bi-directional causality between FDI and growth is found robust to the inclusion of other control variables and using different estimation techniques.

To describe the experience of family members of patients receiving palliative sedation at the initiation of treatment and after the patient has died and to compare these experiences over time.
. Descriptive comparative study.
. Oncology ward at Shaare Zedek Medical Center in Jerusalem, Israel.
. A convenience sample of 34 family members of dying patients receiving palliative sedation. 
. A modified version of a questionnaire describing experiences of family members with palliative sedation was administered during palliative sedation and one to four months after the patient died. Descriptive statistics were used to describe the results of the questionnaire, and appropriate statistical analyses were conducted for comparisons over time.
. Experiences of family members and time.
. Most relatives were satisfied with the sedation and staff support. Palliative sedation was experienced as an ethical way to relieve suffering. However, one-third felt that it shortened the patient's life. An explanation of the treatment was given less than half of the time and was usually given on the same day treatment was started. This explanation was given by physicians and nurses. Many felt that they were not ready for changes in the patient's condition and wanted increased opportunities to discuss the treatment with oncology care providers. No statistically significant differences in experiences were found over time. 
. Relatives' experiences of palliative sedation were generally positive and stable over time. Important experiences included timing of the initiation of sedation, timing and quality of explanations, and communication.
. Nurses should attempt to initiate discussions of the possible role of sedation in the event of refractory symptoms and follow through with continued discussions. The management of refractory symptoms at the end of life, the role of sedation, and communication skills associated with decision making related to palliative sedation should be a

2017-10-01

Dental and dental hygiene clinical faculty members often do not provide consistent instruction, especially since most procedures involve clinical judgment. Although instructional variations frequently translate into variations in student performance, the effect of inconsistent instruction is unknown, especially related to ergonomics. The aim of this study was to determine whether photography-assisted calibration training would improve interrater reliability among dental hygiene faculty members in ergonomics evaluation. The photography-assisted ergonomics calibration program incorporated features to improve accessibility and optimize the quality of the training. The study used a two-group repeated measures design with a convenience sample of 11 dental hygiene faculty members (eight full-time and three part-time) during the autumn 2016 term at one U.S. dental school. At weeks one and seven, all participants evaluated imaged postures of five dental students using a modified-dental operator posture assessment instrument. During weeks three and five, training group participants completed calibration training using independent and group review of imaged postures. All pre-training and post-training evaluations were evaluated for interrater reliability. Two-way random effects intraclass coefficient (ICC) values were calculated to measure the effects of the training on interrater reliability. The average measure of ICC of the training group improved from 0.694 with a 95% confidence interval (CI) of 0.001 to 0.965 (F(4,8)=3.465, p>0.05) to 0.766 with a 95% CI of 0.098 to 0.972 (F(4,8)=7.913, p<0.01). The average measure of ICC of the control group improved from 0.821 with a 95% CI of 0.480 to 0.978 (F(4,28)=7.702, p<0.01) to 0.846 with a 95% CI of 0.542 to 0.981 (F(4,28)=8.561, p<0.01). These results showed that the photography-assisted calibration training with the opportunity to reconcile different opinions resulted in improved agreement among these faculty members.

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.

2017-07-04

Metabolomics is a critical member in systems biology. Although great progress has been achieved in metabolomics, there are still some problems in sample preparation, data processing and data interpretation. In this review, we intend to explore the roles, challenges and trends in sample preparation for mass spectrometry- (MS-) based metabolomics. The newly emerged sample preparation methods were also critically examined, including laser microdissection, in vivo sampling, dried blood spot, microwave, ultrasound and enzyme-assisted extraction, as well as microextraction techniques. Finally, we provide some conclusions and perspectives for sample preparation in MS-based metabolomics.

Determination of essential and toxic elements in tobacco samples from Mexican cigarettes by TXRF

Martinez, T.; Lartigue, J.; Cabrera, L.; Avila-Perez, P.; Zarazua, G.; Tejeda, S.

2005-01-01

Cigarette smoking and tobacco chewing account together for a large number of deaths every day. Numerous studies have identified an important number of inorganic toxic elements along with organic carcinogen and radioactive elements in tobacco. It has been long suspected that, apart from organic and radioactive carcinogens, some inorganic elements may also be the cause of tobacco toxicity, altering the metabolism thus provoking the growth of tumors. In this work we have analyzed 9 different brands of cigarettes sold in the Mexican Market. Macerated tobacco samples after dried, were weighted, placed into the microwave vessel and digested in a mixture of suprapure nitric and hydrochloric acids. The vessel was then sealed and placed into the microwave digestor for dissolution and digestion following the ramp of temperature and pressure. When digestion was completed, the vessels are removed from the digestor, allowed to cool, and transferred to volumetric flaks where they were taken to a volume with de-ionized water. Aliquots of the digestate were analyzed in a Total X-ray Fluorescence Spectrometer Model TX-2000. At the same time and in the same way were treated a NIST 1573 standard of tomato leaves and a blank, the former to chek the elemental recovery and the latter to correct elemental concentration of samples. Results show the presence of some toxic elements such as Pb, Cr, Ni as well as essential elements such as K, Ca, etc. Results were compared with available data on some foreing brands tobacco; the probable reason for the diference in the contents of some of the elements found in Mexican brands are discussed.

Explore relationships among traumatic brain injury (TBI), substance misuse and other mental health disorders in US service members and to identify risk factors for substance misuse. Service members (n = 93 in final sample) injured while deployed to Operation Enduring Freedom or Operation Iraqi Freedom. Longitudinal survey at 6 and 12 months post-intake. The following measures were used: problem substance use, Alcohol Expectancies Questionnaire-III, MINI International Neuropsychiatric Interview Substance Abuse Modules, Ohio State University TBI Identification Method, Neurobehavioural Symptom Inventory, Rivermead Post-Concussion Symptoms Questionnaire, Buss-Perry Aggression Questionnaire, Post-Traumatic Stress Disorder Checklist-Civilian Version, Beck Depression Inventory-II, Beck Anxiety Inventory. More severe TBI and post-traumatic stress disorder (PTSD) symptoms at 6 months post-enrolment were associated with decreased odds of substance misuse 12 months after study enrolment. Alcohol expectancies and incurring a TBI at a younger age increased the odds of substance misuse. While the ability to generalize the current findings to a larger population is limited, the results provide direction for future studies on the prevention and treatment of substance misuse following TBI. The unexpected protective effect of more severe TBI may result from prospective attention to the injury and its consequences. Greater preventive benefit may result from identifying more service members with elevated risk. Lifetime history of TBI and alcohol expectancies may be candidate indicators for greater attention.

Probability Sampling Method for a Hidden Population Using Respondent-Driven Sampling: Simulation for Cancer Survivors.

Science.gov (United States)

Jung, Minsoo

2015-01-01

When there is no sampling frame within a certain group or the group is concerned that making its population public would bring social stigma, we say the population is hidden. It is difficult to approach this kind of population survey-methodologically because the response rate is low and its members are not quite honest with their responses when probability sampling is used. The only alternative known to address the problems caused by previous methods such as snowball sampling is respondent-driven sampling (RDS), which was developed by Heckathorn and his colleagues. RDS is based on a Markov chain, and uses the social network information of the respondent. This characteristic allows for probability sampling when we survey a hidden population. We verified through computer simulation whether RDS can be used on a hidden population of cancer survivors. According to the simulation results of this thesis, the chain-referral sampling of RDS tends to minimize as the sample gets bigger, and it becomes stabilized as the wave progresses. Therefore, it shows that the final sample information can be completely independent from the initial seeds if a certain level of sample size is secured even if the initial seeds were selected through convenient sampling. Thus, RDS can be considered as an alternative which can improve upon both key informant sampling and ethnographic surveys, and it needs to be utilized for various cases domestically as well.

Sadler, Georgia Robins; Lee, Hau-Chen; Lim, Rod Seung-Hwan; Fullerton, Judith

2010-09-01

Nurse researchers and educators often engage in outreach to narrowly defined populations. This article offers examples of how variations on the snowball sampling recruitment strategy can be applied in the creation of culturally appropriate, community-based information dissemination efforts related to recruitment to health education programs and research studies. Examples from the primary author's program of research are provided to demonstrate how adaptations of snowball sampling can be used effectively in the recruitment of members of traditionally underserved or vulnerable populations. The adaptation of snowball sampling techniques, as described in this article, helped the authors to gain access to each of the more-vulnerable population groups of interest. The use of culturally sensitive recruitment strategies is both appropriate and effective in enlisting the involvement of members of vulnerable populations. Adaptations of snowball sampling strategies should be considered when recruiting participants for education programs or for research studies when the recruitment of a population-based sample is not essential.

Highlights: • Develop a new explosive welding method to fabricate the cooling channel of FW. • Utilize effective energy model to accurately calculate optimal welding parameters. • Provide an efficient way for manufacturing high-ductility hollow structural member. - Abstract: In this study, a new explosive welding method provided an effective way for manufacturing ITER-grade 316L(N)/CuCrZr hollow structural member. The welding parameters (stand-off distance and explosion rate) were calculated respectively using equivalent frontal collision wave model and effective energy model. The welded samples were subject to two step heat treatment cycles (solution annealing and aging). Optical microscopy (OM) and scanning electron microscopy (SEM) were utilized to analyze the microstructure of bonding interface. The mechanical properties of the welded samples were evaluated through microhardness test and tensile test. Moreover, the sealing property of the welded specimens was measured through helium leak test. Microstructural analysis showed that the welded sample using effective energy model had an ideal wavy interface. The results of microhardness test revealed an increase in hardness for both sides near to the bonding interface. And the hardening phenomenon of interface region disappeared after the solution annealing. SEM observation indicated that the samples with the post heat treatments exhibited a ductile fracture with dimple features after tensile test. After the specimens undergo aging strengthening, there was an obvious increase in the strength for all specimens. The helium leak test results have proven that the welded specimens are soundness.

To describe Nurses' views of forensic care provided for victims of violence and their families in EDs, to identify factors associated with Nurses' attitudes towards families in care and to investigate if these attitudes were associated with the involvement of patients' families in care. Interpersonal violence has serious health consequences for individuals and family members. Emergency departments provide care for victims of violence, and nurses play a key role in forensic care. However, there is limited knowledge of their views and their involvement of family members. A cross-sectional design was used with a sample of all registered nurses (n = 867) in 28 emergency departments in Sweden. A self-report questionnaire, including the instrument Families' Importance in Nursing Care - Nurses' Attitudes, was used to collect data. Descriptive statistics, multiple linear regression and ordinal regression were used to analyse data. Four hundred and fifty-seven nurses completed the questionnaire (53%). Most nurses provided forensic care, but few had specific education for this task. Policy documents and routines existed for specific patient groups. Most nurses involved family members in care although education and policy documents rarely included them. Being a woman, policy documents and own experience of a critically ill family member were associated with a positive attitude towards family. A positive attitude towards family members was associated with involving patients' families in care. Many emergency department nurses provided forensic care without having specific education, and policy documents only concerned women and children. Nurses' positive attitude to family members was not reflected in policies or education. These results can inspire clinical forensic care interventions in emergency departments. Educational efforts for nurses and policies for all groups of victims of violence are needed. Emergency departments may need to rethink how family members are included

Effect of Paecilomyces lilacinus, Trichoderma harzianum and Trichoderma virens fungal extracts on the hatchability of Ancylostoma eggs.

Hofstätter, Bianca Delgado Menezes; Oliveira da Silva Fonseca, Anelise; de Souza Maia Filho, Fernando; de Souza Silveira, Julia; Persici, Beatriz Maroneze; Pötter, Luciana; Silveira, Andressa; Antoniolli, Zaida Inês; Brayer Pereira, Daniela Isabel

Ancylostoma species have demanded attention due to their zoonotic potential. The use of anthelmintics is the usual method to prevent environmental contamination by Ancylostoma eggs and larvae. Nematophagous fungi have been widely used in their biological control due to the fungus ability to capture and digest free nematode forms. The aim of this study was to evaluate the effect of four different fungal extracts of Paecilomyces lilacinus (n=2), Trichoderma harzianum (n=1) and Trichoderma virens (n=1) isolates on the hatchability of Ancylostoma eggs. Fungal extracts consisted of fungal broth culture supernatant without filtration (crude extract) and filtered broth (filtered extract), macerated mycelium (crude macerate), and macerated mycelium submitted to filtration (filtered macerate). The Ancylostoma eggs were obtained from the feces of naturally infected dogs. In vitro assays were performed in five replicates and consisted of four treatments and one control group. The activity of the fungal extracts of each evaluated fungus differed (p<0.05) from those of the control group, showing significant ovicidal activity. The hatching of the eggs suffered reduction percentages of 68.43% and 47.05% with P. lilacinus, and 56.43% with T. harzianum, when crude macerate extract was used. The reduction with the macerate extract of T. virens was slightly lower (52.25%) than that for the filtered macerate (53.64%). The results showed that all extracts were effective in reducing the hatchability of Ancylostoma eggs. The ovicidal effect observed is likely to have been caused by the action of hydrolytic enzymes secreted by the fungi. Copyright © 2016 Asociación Española de Micología.

Eckerlin, Denise M; Kovalesky, Andrea; Jakupcak, Matthew

2016-09-01

: The experience of military sexual trauma (MST), which can result from assault, battery, or harassment of a sexual nature, may jeopardize the mental health of service members as well as that of their family members, colleagues, and community members. Although a greater proportion of female than male service members are subjected to MST, the Department of Defense estimates that the absolute numbers of affected men and women, across all ranks and branches of military service, are nearly equal because roughly 85% of military members are men. Little research has explored the effects of MST on men. This article discusses the unique ways in which men may experience MST, and examines how social stereotypes of masculinity, myths surrounding sexual assault, and military culture and structure often influence a man's interpretation of an attack and his likelihood of reporting the incident or seeking treatment. It describes current treatments for MST-related mental health conditions and addresses implications for nurses and other health care professionals.

STRUCTURAL PERFORMANCE OF DEGRADED REINFORCED CONCRETE MEMBERS

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

Family members are often the primary caregiver for autistic adults and this responsibility may impact on the carer's wellbeing and quality of life. 109 family members of autistic adults completed an online survey assessing their wellbeing relating to their caring role for their autistic relative. Family members who were supporting an autistic relative with co-occurring mental health difficulties and who they reported as unprepared for the future, self-reported higher levels of worry, depression, anxiety and stress, and poorer quality of life. These findings emphasise the importance of support for family members of autistic adults, whether through external services to support their relative or individual mental health support for the carer.

Full Text Available The Timan-Pechora basin still has a large importance and as a potential region for the hydrocarbons mining in Russia. At present, new facts are emerging from oil and gas exploration. The authors studied more than 50 samples from 11 wells. Most samples in this series were related to the Middle-Late-Frasnian sediments (Late Devonian, which are allocated in «domanic» horizon. Organic macerals of the studed samples are represented both by fragments of humic macerals and sapropelic OM (formed from algal material. The common organic macerals in Timan-Pechora basin are bituminites. They were met in all samples without exception and provide total content of OM,% in the rock. Bituminites are regularly distributed among mineral matter and color the rock in gray or more dark colors. Bituminite was used to determine the reflectance index (RB,% that later was converted into the corresponding equivalent of vitrinite reflectance index (RVeq,%. This is particularly important as authors’ information was used together with the results of earlier studies. ID-modeling has been made in the program PetroMod (2015.1 Schlumberger and helped to understand evolution in Timan-Pechora basin and maturity degree of rocks. The concept of the model was coordinated with the main evolution stages of the northeast European Platform and the foredeep Ural trough. The thicknesses of catagenesis zones and position of boundaries between them are indicators of thermal regime in the analyzed regions. The heat flow used in the modelling was one and the same for most tectonic regions (except foredeep Ural trough and Khoreiverskaja depression. According to the classification of the sedimentary basins by P. Robert (1985, 5 regions belong to regions with a normal or slightly hypothermal geothermal regime (heat flow 45-65 mV/m2 and foredeep Ural trough with heat flow up to 74 mV/m2 is a region with a high hyperthermal regime.

Nursing is the largest health care profession, and Institute of Medicine (IOM) nurse members have the potential to contribute to health policy through IOM activities. We studied reported activities of IOM nurse members. To describe activities of IOM nurse members within the IOM. An e-mail survey was conducted that asked nurse IOM members to assess self-reported IOM activities. Of 57 members, 47 had functioning e-mail addresses, and 33 usable responses were received. The survey consisted of 9 questions dealing with roles and responsibilities undertaken in the previous 5 years. Data analyses were descriptive. The data suggest that nurses have made considerable contributions to the IOM and their participation seems to be as high, or higher, than other disciplines. In an era of health care reform, there is additional opportunity for nurse IOM members to enhance their work in the IOM. Copyright © 2012 Elsevier Inc. All rights reserved.

Shielding member for thermonuclear device

Onozuka, Masanori

1997-06-30

In a thermonuclear device for shielding fast neutrons by shielding members disposed in a shielding vessel (vacuum vessel and structures such as a blanket disposed in the vacuum vessel), the shielding member comprises a large number of shielding wires formed fine and short so as to have elasticity. The shielding wires are sealed in a shielding vessel together with water, and when the width of the shielding vessel is changed, the shielding wires follow after the change of the width while elastically deforming in the shielding vessel, so that great stress and deformation are not formed thereby enabling to improve reliability. In addition, the length, the diameter and the shape of each of the shielding wires can be selected in accordance with the shielding space of the shielding vessel. Even if the shape of the shielding vessel is complicated, the shielding wires can be inserted easily. Accordingly, the filling rate of the shielding members can be changed easily. It can be produced more easily compared with a conventional spherical pebbles. It can be produced more easily than existent spherical shielding pebbles thereby enabling to reduce the production cost.

Zhang, Shujuan; Petersen, Mikael Agerlin; Liu, Jing

2015-01-01

Solaris is a new disease tolerant cultivar increasingly cultivated in cool climate regions. In order to explore the winemaking processes' potential to make different styles of Solaris wines, the effects of different pre-fermentation treatments (direct press after crushing, whole cluster press, cold...... maceration, and skin fermentation) on the volatile profile, chemical, and sensory properties of Solaris wines were investigated. Cold maceration treatment for 24 h and fermentation on skin led to wines with lower acidity and higher glycerol and total polyphenol indexes. Sensory analysis showed that cold...... maceration enhanced "apricot" and "apple" flavor while skin fermentation gave rise to increased "rose" and "elderflower" flavor. The PLS regression model revealed that fruity flavor of cold macerated wines was related to a combination of esters while β-damascenone and linalool were correlated to the "rose...

Partido, Brian B; Jones, Archie A; English, Dana L; Nguyen, Carol A; Jacks, Mary E

2015-02-01

Dental and dental hygiene faculty members often do not provide consistent instruction in the clinical environment, especially in tasks requiring clinical judgment. From previous efforts to calibrate faculty members in calculus detection using typodonts, researchers have suggested using human subjects and emerging technology to improve consistency in clinical instruction. The purpose of this pilot study was to determine if a dental endoscopy-assisted training program would improve intra- and interrater reliability of dental hygiene faculty members in calculus detection. Training included an ODU 11/12 explorer, typodonts, and dental endoscopy. A convenience sample of six participants was recruited from the dental hygiene faculty at a California community college, and a two-group randomized experimental design was utilized. Intra- and interrater reliability was measured before and after calibration training. Pretest and posttest Kappa averages of all participants were compared using repeated measures (split-plot) ANOVA to determine the effectiveness of the calibration training on intra- and interrater reliability. The results showed that both kinds of reliability significantly improved for all participants and the training group improved significantly in interrater reliability from pretest to posttest. Calibration training was beneficial to these dental hygiene faculty members, especially those beginning with less than full agreement. This study suggests that calculus detection calibration training utilizing dental endoscopy can effectively improve interrater reliability of dental and dental hygiene clinical educators. Future studies should include human subjects, involve more participants at multiple locations, and determine whether improved rater reliability can be sustained over time.

Summary evaluation of Yucca Mountain surface transects with implications for downhole sampling. Yucca Mountain Site Characterization Project

International Nuclear Information System (INIS)

Mckenna, S.A.; Rautman, C.A.

1995-06-01

The results of previously completed vertical outcrop sampling transacts are summarized with respect to planning downhole sampling. The summary includes statistical descriptions and descriptions of the spatial variability of the sampled parameters. Descriptions are made on each individual transect, each thermal/mechanical unit and each previously defined geohydrologic unit. Correlations between parameters indicate that saturated hydraulic conductivity is not globally correlated to porosity. The correlation between porosity and saturated hydraulic conductivity is both spatially and lithologically dependent. Currently, there are not enough saturated hydraulic conductivity and sorptivity data to define relationships between these properties and porosity on a unit by unit basis. Also, the Prow Pass member of the Crater Flat Tuff and stratigraphically lower units have gone essentially unsampled in these outcrop transacts. The vertical correlation length for hydrologic properties is not constant across the area of the transacts. The average sample spacing within the transacts ranges from 1.25 to 2.1 meters. It appears that, with the exception of the Topopah Spring member units, a comparable sample spacing will give adequate results in the downhole sampling campaign even with the nonstationarity of the vertical correlation. The properties within the thermal/mechanical units and geohydrologic units of the Topopah Spring member appear to have a spatial correlation range less than or equal to the current sample spacing within these units. For the downhole sampling, a sample spacing of less than 1.0 meters may be necessary within these units

The purpose of this study was to examine the association between members' perceptions of staffs behaviors, motivational climate, their own behaviors, commitment to future exercise, and life satisfaction in a group-fitness setting. The theory-driven hypothesized mediating role of perceptions of the climate was also tested. Members (N = 5,541) of a national group-fitness studio franchise completed a survey regarding their class experiences. The survey included questions that measured participants' perceptions of the motivational climate (caring, task-involving, ego-involving), perceptions of staff's behaviors, their own behaviors, commitment to exercise, and life satisfaction. Structural equation modeling was used to assess both the association between variables and the theoretically driven predictive relationships. The participants perceived the environment as highly caring and task-involving and low ego-involving. They reported high exercise commitment and moderately high life satisfaction and perceived that the staffs and their own behaviors reflected caring, task-involving characteristics. Structural equation modeling demonstrated that those who perceived a higher caring, task-involving climate and lower ego-involving climate were more likely to report more task-involving, caring behaviors among the staff and themselves as well as greater commitment to exercise. In addition, a theory-driven mediational model suggested that staff behaviors may be an antecedent to members' exercise experiences by impacting their perceptions of the climate. The results of this study give direction to specific behaviors in which staff of group-fitness programs might engage to positively influence members' exercise experiences.

Burnout syndrome is one of the consequences and the results of occupational or job stress emerged in the form of emotional exhaustion feeling, depersonalization and decrement personal accomplishment. The aim of this study was to determine the occupational stress and its relationship with burnout syndrome in the academic members of Lorestan University of Medical Sciences. This descriptive cross-sectional survey was conducted on 111 of the faculty members via multistage sampling. Data were collected by the questionnaire of Maslach Burnout Inventory (MBI), and Osipow Occupational Stress Inventory (OSI- R). Data were analyzed by using descriptive statistics as well as analytical statistics such as chi square, Kruskal-Wallis, Mann Whitney tests and Pearson correlation coefficient. The results showed that the most of the participants had a low level of burnout three dimensions including emotional burnout (72.1%), depersonalization (81.1%), and the decrement of personal accomplishment (56.8%). Moreover 79.3% of samples had a low occupational stress, but there was a meaningful relationship between occupational stress and dimensions of burnout syndrome with an exception for the intensity of decrement of personal accomplishment. Academic members were in an appropriate condition concerning burnout syndrome and occupational stress. However by applying some strategies to decrease stress and determining stress resources, we can improve their psychological health of academic members.

Petrinec, Amy B; Daly, Barbara J

2016-01-01

Family members of intensive care unit (ICU) patients are at risk for symptoms of post-traumatic stress disorder (PTSD) following ICU discharge. The aim of this systematic review is to examine the current literature regarding post-ICU family PTSD symptoms with an emphasis on methodological issues in conducting research on this challenging phenomenon. An extensive review of the literature was performed confining the search to English language studies reporting PTSD symptoms in adult family members of adult ICU patients. Ten studies were identified for review published from 2004 to 2012. Findings demonstrate a significant prevalence of family PTSD symptoms in the months following ICU hospitalization. However, there are several methodological challenges to the interpretation of existing studies and to the conduct of future research including differences in sampling, identification of risk factors and covariates of PTSD, and lack of consensus regarding the most appropriate PTSD symptom measurement tools and timing. © The Author(s) 2014.

In Cameroonian traditional medicine various extracts of Gladiolus dalenii Van Geel (Iridaceae) have been used as a cure for various ailments that include headaches, digestive problems, muscle and joint aches, and some central nervous system disorders such as epilepsy, schizophrenia and mood disorders. Owning to this background, the aim of the study was to investigate whether an aqueous macerate of the bulb of Gladiolus dalenii has any antidepressant activity focusing specifically on depression-like behaviours associated with epilepsy. We used the combined administration of atropine and pilocarpine to rats as our animal model of epilepsy. The forced swim test and spontaneous locomotor activity in the open field test were the two tools used to assess the presence of depression-like behaviour in epileptic and control animals. The following depression-related parameters were determined: plasma ACTH, plasma corticosterone, adrenal gland weight and hippocampal levels of brain-derived neurotrophic factor (BDNF). The effects of Gladiolus dalenii were compared to that of fluoxetine. Our results showed that we had a valid animal model of epilepsy-induced depression as all 3 measures of construct, predictive and face validity were satisfied. The data indicated that Gladiolus dalenii significantly reduced the immobility times in the forced swim test and the locomotor activity as assessed in the open field. A similar pattern was observed when the HPA axis parameters were analysed. Gladiolus dalenii significantly reduced the levels of ACTH, corticosterone, but not the adrenal gland weight. Gladiolus dalenii significantly increased the level of BDNF in the hippocampus. In all parameters measured the effects of Gladiolus dalenii were significantly greater than those of fluoxetine. The results show that Gladiolus dalenii has antidepressant-like properties similar to those of fluoxetine in epilepsy-associated depressive states. The antidepressant activity of Gladiolus dalenii is

To compare symptom reporting patterns of service members with a history of concussion based on work status: full duty, limited duty, or in the Medical Evaluation Board (MEB)/disability process. Retrospective analysis of 181 service members with a history of concussion (MEB n = 56; limited duty n = 62; full duty n = 63). Neurobehavioral Symptom Inventory (NSI) Validity-10 cutoff (>22) and Mild Brain Injury Atypical Symptoms Scale (mBIAS) cutoffs (≥10 and ≥8) were used to evaluate potential over-reporting of symptoms. The MEB group displayed significantly higher NSI scores and significantly higher proportion scored above the mBIAS ≥10 cutoff (MEB = 15%; limited duty = 3%; full duty = 5%). Validity-10 cutoff did not distinguish between groups. MEB but not limited duty status was associated with increased risk of over-reporting symptoms in service members with a history of concussion. Results support the use of screening measures for over-reporting in the MEB/disability samples.

Recent advances in the field of 16-membered macrolide antibiotics.

Cui, W; Ma, S

2011-10-01

The continuing emergence of bacterial resistance has provided an incentive for recent intensified research on macrolide antibiotics. Belonging to the macrolide family, 16-membered macrolides also experience a renewed interest in further exploration. The medicinal potential of 16-membered macrolides in search for new antibacterials stems from some advantages over 14-membered macrolides, such as gastrointestinal tolerability, structural flexibility, and lack of inducible resistance. Thus, compared with abundant articles on various 14-membered macrolide derivatives in the literature, this review will highlight some representative 16-membered macrolide antibiotics and their recently discovered analogs. Furthermore, the action and resistance mechanisms of 16-membered macrolide antibiotics will be elucidated as well to assist the drug design.

Chun, Jinseok S; Choi, Jin Nam

2014-05-01

Focusing on "what people want in their group" as a critical antecedent of intragroup conflict, the present study theorizes and empirically investigates the relationships among the psychological needs of group members, intragroup conflict, and group performance. It attends to the within-group average and dispersion of members' psychological needs and examines the effects stemming from group composition of needs on multiple types of conflict. The analyses based on multisource data from 145 organizational teams revealed significant relationships between the groups' composition with respect to the members' need for achievement and task conflict, need for affiliation and relationship conflict, and need for power and status conflict. Some of these relationships were moderated by open communication among members. The analyses also demonstrated that when the 3 types of conflict were considered together, task conflict was a positive predictor of group performance, whereas relationship conflict was a negative predictor. The findings highlight the motivational aspects of intragroup conflict, revealing the multilevel dynamics of the psychological needs in social settings. (c) 2014 APA, all rights reserved.

Oil reservoirs are major sites of methane production and carbon turnover, processes with significant impacts on energy resources and global biogeochemical cycles. We applied a cultivation-independent genomic approach to define microbial community membership and predict roles for specific organisms in biogeochemical transformations in Alaska North Slope oil fields. Produced water samples were collected from six locations between 1,128 m (24 to 27°C) and 2,743 m (80 to 83°C) below the surface. Microbial community complexity decreased with increasing temperature, and the potential to degrade hydrocarbon compounds was most prevalent in the lower-temperature reservoirs. Sulfate availability, rather than sulfate reduction potential, seems to be the limiting factor for sulfide production in some of the reservoirs under investigation. Most microorganisms in the intermediate- and higher-temperature samples were related to previously studied methanogenic and nonmethanogenic archaea and thermophilic bacteria, but one candidate phylum bacterium, a member of the Acetothermia (OP1), was present in Kuparuk sample K3. The greatest numbers of candidate phyla were recovered from the mesothermic reservoir samples SB1 and SB2. We reconstructed a nearly complete genome for an organism from the candidate phylum Parcubacteria (OD1) that was abundant in sample SB1. Consistent with prior findings for members of this lineage, the OD1 genome is small, and metabolic predictions support an obligately anaerobic, fermentation-based lifestyle. At moderate abundance in samples SB1 and SB2 were members of bacteria from other candidate phyla, including Microgenomates (OP11), Atribacteria (OP9), candidate phyla TA06 and WS6, and Marinimicrobia (SAR406). The results presented here elucidate potential roles of organisms in oil reservoir biological processes. The activities of microorganisms in oil reservoirs impact petroleum resource quality and the global carbon cycle. We show that bacteria

Method for brazing together planar and nonplanar metal members

International Nuclear Information System (INIS)

Hammersand, F.G.; Witkowski, A.J.

1985-01-01

The invention relates to a method and apparatus for brazing two metal members together, at least one of which is nonplanar, in a brazing furnace using a substantially pure brazing material. The method comprises the steps of utilizing a brazing fixture to hold the two metal members in tangential relation to one another along a portion of each member so that a cavity is formed adjacent to the contacting portions. A braze material is then positioned within the cavity. The braze fixture, the metal members, and the braze material are then placed in a brazing furnace. A heat shield is then placed over the braze fixture, the metal members, and the braze material to shield the braze material from direct furnace radiation. The furnace temperature is linearly increased at a rate of about 180 0 C. per hour until a temperature of 350 0 C. is achieved. Heat is transferred by conduction from the metal members to the braze material to cause the braze material to melt. Some material from the metal members slowly diffuses into the braze material forming a braze joint. The furnace is rapidly cooled to room temperature using nitrogen gas. The brazed assemblies made according to this method are superior to assemblies formed by heliarc welding

AGU has recently established a new customer "support line"—solutions@agu.org—as the point of contact on AGU's staff for members and other individual constituents who have not been able to resolve issues or get questions answered promptly or to their satisfaction through customary channels.Over the past year, there have been many changes at AGU. Unfortunately—and perhaps as a result of these changes—communication with members and individual constituents has suffered. Some individuals report, for example, that e-mail messages are not answered to their satisfaction, or in a timely manner. Instructions on AGU's Web site are unclear in some areas. Problems related specifically to the transition to electronic publishing are cropping up.

Member State Event: Telling CERN's Story

CERN Multimedia

2004-01-01

As part of the events to mark the Laboratory's fiftieth anniversary, members of the CERN personnel are telling the story of CERN. Robert Cailliau (on the right of the photograph), co-inventor of the Web and currently responsible for CERN's external communications, and Chiara Mariotti (in the center), a physicist working at CMS, were invited to talk about the history of CERN and the Web at a conference in the 'Science Thursdays' series entitled 'From the Quark to the Web' in Turin on 26 February. This was not their first appearance before a non-specialist audience (almost 1000 people that day!) eager to find out what goes on in a unique research centre like CERN as talking about the Laboratory's activities and its history are part and parcel of their work for the Organization. Anniversary Events in the Member States: This 'Science Thursday' event devoted to CERN was one of Italy's contributions to CERN's fiftieth anniversary celebrations. Coming up soon in the Member States: Italy International Centre...

Nurse researchers and educators often engage in outreach to narrowly defined populations. This article offers examples of how variations on the snowball sampling recruitment strategy can be applied in the creation of culturally appropriate, community-based information dissemination efforts related to recruitment to health education programs and research studies. Examples from the primary author’s program of research are provided to demonstrate how adaptations of snowball sampling can be effectively used in the recruitment of members of traditionally underserved or vulnerable populations. The adaptation of snowball sampling techniques, as described in this article, helped the authors to gain access to each of the more vulnerable population groups of interest. The use of culturally sensitive recruitment strategies is both appropriate and effective in enlisting the involvement of members of vulnerable populations. Adaptations of snowball sampling strategies should be considered when recruiting participants for education programs or subjects for research studies when recruitment of a population based sample is not essential.

Understanding type 2 diabetes: including the family member's perspective.

LENUS (Irish Health Repository)

White, Patricia

2012-02-01

PURPOSE: The purpose of this study was to examine the relationship between psychological and social factors and diabetes outcomes in people with type 2 diabetes and their family members. 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.

Hazard analysis of food preparation practices were conducted in four households and eleven others were visited to survey both food preparation practices and environmental conditions. Households selected had members who were suffering from either diarrhea of unknown etiology or alleged typhoid fever. Hazard analyses and sanitary surveys included gathering data on time-temperature exposures of foods, collecting samples of food and drinking water, sampling sewage or drains, and obtaining stool specimens from persons with diarrhea and from family controls. Food samples were tested for aerobic mesophilic colony counts and common foodborne pathogens; specimens were tested for Salmonella, Shigella, Campylobacter and Yersinia. Campylobacter was isolated from two persons purported to have diarrhea, but neither Salmonella, Shigella nor Yersinia were recovered from alleged cases or controls. Salmonella agona was recovered from a latrine. Most foods were cooked to internal temperatures to or near to boiling. Those not promptly eaten were held at ambient room or outside temperatures until a subsequent meal, until a family member returned home, or until lunch time when taken to the fields. During these intervals, microorganisms multiplied and mesophilic aerobic organisms increased often reaching 10(8)/g or greater before consumption. None of these foods were reheated before eating. Bacillus cereus was isolated from 4 of 10 samples; one sample of 'moro' (beans and rice) exceeded 10(6)/g, two other samples exceeded 10(3)/g. Staphylococcus aureus was isolated from 7 of 14 samples, one exceeded 10(5)/g. Fecal coliforms were isolated from 8 of 14 food samples, five exceeded 10(5)/g. Neither Salmonella nor Shigella were isolated from any food, the community water supplies or from vessels of water within houses. Fecal coliform counts of water were less than 3/ml, except one sample from a clay vessel (9/ml). Risks associated with cooked foods which were not promptly eaten appeared to be

Experimental testing is commonly used as one of the steps to determine the cause of the collapse of a building structure. The collapse of structures can be due to low quality materials. Although material samples have passed laboratory tests and the existing technical specifications have been met but there may be undetected defects and known material after failure. In this paper will be presented Experimental Testing of Axially Tension Cold Formed Steel Channel Members to determine the cause of the collapse of a building roof truss x in Pekanbaru. Test of tensile strength material cold formed channel sections was performed to obtain the main characteristics of Cold Formed steel material, namely ultimate tensile strength loads that can be held by members and the yield stress possessed by channel sections used in construction. Analysis of axially tension cold formed steel channel section presents in this paper was conducted through experimental study based on specificationsAnnualBook of ASTM Standards: Metal Test methods and Analitical Procedures, Section 3 (1991). The result of capacity loads experimental test was compared with design based on SNI 03-7971-2013standard of Indonesia for the design of cold formed steel structural members. The results of the yield stress of the material will be seen against the minimum allowable allowable stress range. After the test, the percentace of ultimate axial tension capacity theory has a result that is 16.46% larger than the ultimate axial tension capacity experimental. When compared with the load that must be borne 5.673 kN/m it can be concluded that 2 specimens do not meet. Yield stress of member has fulfilled requirement that wass bigger than 550 MPa. Based on the curve obtained ultimate axial tension capacity theory, results greater than experimental. The greatest voltage value (fu) is achieved under the same conditions as its yield stress. For this specimen with a melting voltage value fy = 571.5068 MPa has fulfilled the

This paper presents work to identify factors affecting effectiveness of agri-business ventures (A-BVs) on the side of providers as perceived by their members. A survey was conducted among 95 members of A-BVs in Zanjan province, Iran. To collect data, a questionnaire was designed. Two distinct groups of A-BVs with low (group 1) and high (group 2) perceived (evaluated) levels of effectiveness were revealed. The study showed that there were significant differences between the two groups on important characteristics of A-BVs and their members. The study also found that there were statistically significant relationships between A-BVs' governance structure and capacity, management and organization characteristics and the perceived effectiveness, whereas there were no statistically significant relationships between A-BVs' advisory methods characteristic applied by members and the perceived effectiveness. Logistic regression results also showed that level of application of rules encouraging members' active participation in important decision makings, clear terms of reference to guide contracting procedures, roles, and responsibilities of parties involved, type of people served and geographical area of program coverage, and members' ability to use Information and Communication Technologies (ICTs) were predictors of the perceived (evaluated) effectiveness of A-BVs. The study showed that evaluation of members of effectiveness of A-BVs would not be the same. It is suggested that Iranian public agricultural extension organization, as responsible organization for monitoring and evaluating services conducted by A-BVs, considered these differences between members with different levels of some important variables. 2010 Elsevier Ltd.

Research in crisis areas indicate that survivors' responses to the forced disappearance of family members are similar to reactions to other traumatic events. The aim of this study was to determine the presence of symptoms of posttraumatic stress disorder (PTSD) in women with war missing family members in Bosnia and Herzegovina 18 years after the war in this region (1992-1995). The study included 160 women aged 47.1±14.0 from three regions of Bosnia and Herzegovina. It was carried out in the period from April 2010 to May 2011. Of the 160 participants, 120 women had a war missing family member and 40 women had no war missing family members. The Harvard Trauma Questionnaire (HTQ), the Beck Depression Inventory (BDI) and the Hamilton Anxiety Rating Scale (HAMA) were used for data collection. Basic socio-demographic data and data concerning the missing family members were also collected. Women with war missing family members experienced significantly more traumatic war experiences (18.43±5.27 vs 6.57±4.34, pfamily members. Women with war missing family members showed significantly more severe PTSD symptoms. Based on the results of this study, it was determined that the forced disappearance of a family member is an ambiguous situation that can be characterized as a traumatic experience.

Unrecognized pediatric and adult family members of children with acute brucellosis.

Science.gov (United States)

Çiftdoğan, Dilek Yılmaz; Aslan, Selda

Brucellosis is an infectious, contagious and zoonotic disease that occurs worldwide. The family members of an index case of brucellosis may be especially susceptible, due to sharing the same source of infection and similar risk factors for brucellosis. In this study, we propose to screen pediatric and adult family members of brucellosis index cases for detecting additional unrecognized infected family members. 114 family members of 41 pediatric patients with brucellosis were evaluated. All family members completed a brief questionnaire and were tested by a standard tube agglutination test (STA). The majority of family members (n=96, 84.2%) were children. Among the 114 family members, 42 (36.8%) were seropositive, and 15 (35.7%) were symptomatic. The majority of the symptomatic seropositive family members (n=12, 80%) had STA titers (≥1:640) higher than asymptomatic seropositive family members (n=9, 33%; p=0.004). The routine screening of both pediatric and adult family members of index cases is a priority in endemic areas. Using this screening approach, unrecognized family members who are seropositive for brucellosis will be identified earlier and be able to receive prompt treatment.

To study knowledge and attitudes of hospital ethics committee members at the first workshop for ethics committees in Croatia. Before/after cross-sectional study using a self administered questionnaire. Educational workshop for members of hospital ethics committees, Zagreb, 2003. Knowledge and attitudes of participants before and after the workshop; everyday functioning of hospital ethics committees. The majority of the respondents came from committees with at least five members. The majority of ethics committees were appointed by the governing bodies of their hospitals. Most committees were founded after the implementation of the law on health protection in 1997. Membership structure (three physicians and two members from other fields) and functions were established on the basis of that law. Analysis of research protocols was the main part of their work. Other important functions-education, case analysis, guidelines formation-were neglected. Members' level of knowledge was not sufficient for the complicated tasks they were supposed to perform. However, it was significantly higher after the workshop. Most respondents felt their knowledge should be improved by additional education. Their views on certain issues and bioethical dilemmas displayed a high level of paternalism and over protectiveness, which did not change after the workshop. The committees developed according to bureaucratic requirements. Furthermore, there are concerns about members' knowledge levels. More efforts need to be made to use education to improve the quality of the work. Additional research is necessary to explore ethics committees' work in Croatia especially in the hospital setting.

To examine the perceptions of staff members toward the implementation of an animal-assisted activity (AAA) in an outpatient regional cancer center. Quasi-experimental, post-test design. An adult outpatient regional cancer center in northern California. 34 facility staff members. Self-report questionnaire following four weeks of AAA visitation. Visits took place three times a week for a total of 12 visits. Perceptions of the AAA. Previous perceptions toward AAA influenced the perceptions of the visitation's efficacy. Direct and indirect interaction with the visiting AAA teams was positively associated with perceptions of the AAA. A disagreement occurred that the AAA had caused extra stress or work for staff. Enjoyment of interacting with the dog handler was not significantly different from interacting with the dog; however, it was more positively correlated to acceptance of the AAA. The study provided evidence that the AAA was generally accepted by staff members. Individual staff members' perceptions of dogs and AAAs can influence their receptivity to AAA interventions. Interaction with AAA teams should be voluntary and available for patients and staff members. AAA may be introduced into facilities without creating the perception of extra stress or work for staff members. Providing staff the opportunity to interact with visiting AAA teams may be beneficial for the success of such programs. The human handler in AAA teams may play a vital role in the staff acceptance of such programs.

The Massachusetts Department of Public Health Overdose Education and Naloxone Distribution Program provides overdose education and naloxone rescue kits to people at risk for overdose and bystanders, including family members. Using Massachusetts Department of Public Health data, the aims are to: (i) describe characteristics of family members who receive naloxone; (ii) identify where family members obtain naloxone; and (iii) describe characteristics of rescues by family members. We conducted a retrospective review using program enrollee information collected on a standardised form between 2008 and 2015. We calculated descriptive statistics, including demographics, current substance use, enrolment location, history of witnessed overdoses and rescue attempt characteristics. We conducted a stratified analysis comparing family members who used drugs with those who did not. Family members were 27% of total program enrollees (n = 10 883/40 801). Family members who reported substance use (n = 4679) were 35.6 years (mean), 50.6% female, 76.3% non-Hispanic white, 75.6% had witnessed an overdose, and they obtained naloxone most frequently at HIV prevention programs. Family members who did not report substance use (n = 6148) were 49.2 years (mean), 73.8% female, 87.9% non-Hispanic white, 35.3% had witnessed an overdose, and they obtained naloxone most frequently at community meetings. Family members were responsible for 20% (n = 860/4373) of the total rescue attempts. The Massachusetts experience demonstrates that family members can be active participants in responding to the overdose epidemic by rescuing family members and others. Targeted intervention strategies for families should be included in efforts to expand overdose education and naloxone in Massachusetts. © 2017 Australasian Professional Society on Alcohol and other Drugs.

Full Text Available This study examines the impact of leader-member exchange (LMX and the moderating role of empowerment on employee voice behavior. A sample of 314 supervisor-subordinate dyadic exchanges was collected from a manufacturing firm in Mainland China. The results provided support the view that LMX and empowerment were both significantly associated with employee voice behavior. The positive relationship between LMX and employee voice behavior was stronger when employees received higher levels of empowerment. Theoretical and managerial implications of the research are discussed.

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.

2011-07-01

The purpose of this study was to test Kanter's theory by examining relationships among structural empowerment, leader-member exchange (LMX) quality and nurses' participation in personal knowledge transfer activities. Despite the current emphasis on evidence-based practice in health care, research suggests that implementation of research findings in everyday clinical practice is unsystematic at best with mixed outcomes. This study was a secondary analysis of data collected using a non-experimental, predictive mailed survey design. A random sample of 400 registered nurses who worked in urban tertiary care hospitals in Ontario yielded a final sample of 234 for a 58.5% response rate. Hierarchical multiple linear regression analysis revealed that the combination of LMX and structural empowerment accounted for 9.1% of the variance in personal knowledge transfer but only total empowerment was a significant independent predictor of knowledge transfer (β=0.291, t=4.012, Pleader-member exchange quality resulted in increased participation in personal knowledge transfer in practice. The results reinforce the pivotal role of nurse managers in supporting empowering work environments that are conducive to transfer of knowledge in practice to provide evidence-based care. © 2011 The Authors.

Donated tissues can save lives of critically burned patients and those needing a heart valve replacement. Tissues enhance the lives of a million recipients annually through transplants of corneas, bones, tendons, and vein grafts. Unfortunately, the need for some tissues exceeds their availability. The goal of the quantitative component of this mixed methods study was to identify the grief, posttraumatic stress, personal growth, and ongoing attachment response of tissue donors' family members during a 2-year period. Simultaneous mixed methods design. The sample for this study consisted of 52 tissue donors' family members, mostly widows (83%). Data were collected for 2 years to test changes in grief, posttraumatic stress, panic behavior, personal growth, and ongoing attachment. The bereaved participants experienced significantly fewer grief reactions, less posttraumatic stress, and greater personal growth. There was no significant difference in the ongoing attachment to their deceased loved ones. The results of this study may reinforce the positive meaning that tissue donors' family members can find in tissue donation. Findings also demonstrate that the bereavement process corroborates contemporary bereavement and attachment theories. Health professionals are encouraged to seek donations with less worry that tissue donors' family members will experience adverse outcomes during bereavement.

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.

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

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

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.

We investigated how group membership impacts valence judgments of ingroup and outgroup members' emotional expressions. In Experiment 1, participants, randomized into 2 novel, competitive groups, rated the valence of in- and outgroup members' facial expressions (e.g., fearful, happy, neutral) using a circumplex affect grid. Across all emotions, participants judged ingroup members' expressions as more positive than outgroup members' expressions. In Experiment 2, participants categorized fearful and happy expressions as being either positive or negative using a mouse-tracking paradigm. Participants exhibited the most direct trajectories toward the "positive" label for ingroup happy expressions and an initial attraction toward positive for ingroup expressions of fear, with outgroup emotion trajectories falling in between. Experiment 3 replicated Experiment 2 and demonstrated that the effect could not be accounted for by targets' gaze direction. Overall, people judged ingroup faces as more positive, regardless of emotion, both in deliberate and implicit judgments. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Although most patients express a preference to die at home, many (over 30 percent) still die in hospital. This study's purpose was to explore the experience of hospital death from the perspective of patients' family members. interviews were conducted with family members of patients who had died at hospitals affiliated with a large tertiary referral centre in the United States. Content analysis was used to analyze findings. We interviewed 30 family members by phone. Themes were arranged by time frame: before death, time of death, and after death. Families do not interpret clinical cues leading up to death in the same way healthcare providers do; families need clear and direct explanations from providers. Clinicians should assess patient and family understandings of prognosis and communicate clearly and directly. Family members value being with their loved one at the time of death, and they value spending time with the body after death; this should be facilitated in clinical practice.

Member Heterogeneity in Agricultural Cooperatives: A Systems-Theoretic Perspective

Directory of Open Access Journals (Sweden)

Constantine Iliopoulos

2018-04-01

Full Text Available All over the globe, cooperatives are plagued by pervasive member heterogeneity problems that are induced by the radical and dynamic changes in the business environment. Most current solutions to these problems emphasize strengthening member loyalty and commitment. Yet, many of these solutions are symptomatic rather than fundamental. Searching for fundamental solutions, this paper draws on the Luhmannian system-environment paradigm. Bringing this paradigm to bear on the cooperative scholarship, the paper views cooperatives as operationally closed systems maintaining a precarious relationship to their outer environment, which includes cooperative members. In view of their operational closure, cooperatives tend to overstrain the carrying capacity of their environment by being active in the areas marked by a limited extent of the true commonness of member interests. This overstraining results in a host of problems associated with member heterogeneity. The fundamental solutions following from the system-environment paradigm require the adjustment of cooperative boundaries and goals in light of the evolving range of the true common interests of members. In terms of methodology, we review the extant literature, synthesize the main elements of the system-environment approach and conduct a meta-analysis of case studies and other empirical research to highlight our theoretical arguments.

Musicians have been reported as having a high prevalence of upper-extremity musculoskeletal disorders, including carpal tunnel syndrome. The purpose of this study was to determine the presence of median and ulnar neuropathies in U.S. Army Medical Command (MEDCOM) Band members at Fort Sam Houston, Texas. Thirty-five MEDCOM Band members (30 males, 5 females) volunteered to participate. There were 33 right-handed musicians, and the mean length of time in the MEDCOM Band was 12.2 yrs (range, 1-30 yrs). Subjects completed a history form, were interviewed, and underwent a physical examination of the cervical spine and bilateral upper extremities. Nerve conduction studies of the bilateral median and ulnar nerves were performed. Electrophysiological variables served as the reference standard for median and ulnar neuropathy and included distal sensory latencies, distal motor latencies, amplitudes, conduction velocities, and comparison study latencies. Ten of the 35 subjects (29%) presented with abnormal electrophysiologic values suggestive of an upper extremity mononeuropathy. Nine of the subjects had abnormal median nerve electrophysiologic values at or distal to the wrist; 2 had bilateral abnormal values. One had an abnormal ulnar nerve electrophysiologic assessment at the elbow. Nine of these 10 subjects had clinical examination findings consistent with the electrophysiological findings. The prevalence of mononeuropathies in this sample of band members is similar to that found in previous research involving civilian musicians (20-36%) and far exceeds that reported in the general population. Prospective research investigating screening, examination items, and injury prevention measures in musicians appears to be warranted.

2,4,6-trichloroanisole (TCA), the cork taint molecule, has been the target of several analytical approaches over the few past years. In spite of the development of highly efficient and sensitive tools for its detection, ranging from advanced chromatography to biosensor-based techniques, a practical breakthrough for routine cork screening purposes has not yet been realized, in part due to the requirement of a lengthy extraction of TCA in organic solvents, mostly 12% ethanol and the high detectability required. In the present report, we present a modification of a previously reported biosensor system based on the measurement of the electric response of cultured fibroblast cells membrane-engineered with the pAb78 TCA-specific antibody. Samples were prepared by macerating cork tissue and mixing it directly with the cellular biorecognition elements, without any intervening extraction process. By using this novel approach, we were able to detect TCA in just five minutes at extremely low concentrations (down to 0.2 ppt). The novel biosensor offers a number of practical benefits, including a very considerable reduction in the total assay time by one day, and a full portability, enabling its direct employment for on-site, high throughput screening of cork in the field and production facilities, without requiring any type of supporting infrastructure.

Taušer Josef

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.

CHIS - Information concerning the health insurance of frontalier workers who are family members of a CHIS main member

CERN Multimedia

2014-01-01

We recently informed you that the Organization was still in discussions with the Host State authorities to clarify the situation regarding the health insurance of frontalier workers who are family members (as defined in the Staff Rules and Regulations) of a CHIS main member, and that we were hoping to arrive at a solution soon.   After extensive exchanges, we finally obtained a response a few days ago from the Swiss authorities, with which we are fully satisfied and which we can summarise as follows: 1) Frontalier workers who are currently using the CHIS as their basic health insurance can continue to do so. 2) Family members who become frontalier workers, or those who have not yet exercised their “right to choose” (droit d’option) can opt to use the CHIS as their basic health insurance. To this end, they must complete the form regarding the health insurance of frontaliers, ticking the LAMal box and submitting their certificate of CHIS membership (available from U...

[Survey on the medical mycology processes to the members of the French Society for Medical Mycology].

The objective of the survey was to describe the practices of clinical laboratories in terms of cultures in medical mycology. We have implemented this project within the members of the French Society for Medical Mycology (SFMM) to evaluate the analytical processes of the mycological examination in our laboratories. This preliminary study would help to suggest the future French guidelines. A questionnaire regarding the processing of mycology analysis was sent to the 227 members of the SFMM in 2009. The data involved 21 types of samples, direct microscopic examination with or without colouring and the reagents, the number of culture media, the types of media (Sabouraud, Sabouraud antibiotic, Sabouraud cycloheximide and chromogenic medium), temperature and duration of the incubation (days) and the existence of a first result before the end of the incubation period. The analytical processes were compared to an accredited laboratory according to EN ISO 15189. A great heterogeneity was observed in the 36 forms from 27 (75%) laboratories belonging to university hospitals among the 38 existing in France. As for deep samples, two microscopic exams were performed, only one was usually done. A more sensitive technique was preferred to the wet-mount for some samples. Routine samples are often inoculated on a chromogenic media. For deep samples two medium are inoculated (chromogenic media, Sabouraud and antibiotics). If the temperature of incubation is unique, 30°C was chosen. A temperature of 37°C was preferred for samples where Candida spp. is selected. When there are two temperatures of incubation, 27°C and 37°C were preferred. Each biologist can compare his proceedings to the other laboratories and to a laboratory already accredited. The question is to find the best strategies for each medical mycology specimen. They will aid the process of accreditation according to EN ISO 15189, which now applies in all laboratories in Europe.

Prolonged mechanical ventilation for acute medical conditions increases the risk of chronic critical illness (CCI). Close family members are confronted with the life-threatening condition of the CCI patients and are prone to develop posttraumatic stress disorder affecting their health-related quality of life (HRQL). Main aim of the present study was to investigate patient- and family-related risk factors for posttraumatic stress and decreased HRQL in family members of CCI patients. In a cross-sectional design nested within a prospective longitudinal cohort study, posttraumatic stress symptoms and quality of life were assessed in family members of CCI patients (n = 83, aged between 18 and 72 years) up to 6 months after transfer from ICU at acute care hospital to post-acute rehabilitation. Patients admitted a large rehabilitation hospital for ventilator weaning. The Posttraumatic Stress Scale-10 and the Euro-Quality of life-5D-3L were applied in both patients and their family members via telephone interview. A significant proportion of CCI patients and their family members (14.5 and 15.7 %, respectively) showed clinically relevant scores of posttraumatic stress. Both CCI patients and family members reported poorer HRQL than a normative sample. Factors independently associated with posttraumatic stress in family members were the time following ICU discharge (β = .256, 95 % confidence interval .053-.470) and the patients' diagnosis of PTSD (β = .264, 95 % confidence interval .045-.453). Perceived satisfaction with the relationship turned out to be a protective factor for posttraumatic stress in family members of CCI patients (β = -.231, 95 % confidence interval -.423 to -.015). Regarding HRQL in family members, patients' acute posttraumatic stress at ICU (β = -.290, 95 % confidence interval -.360 to -.088) and their own posttraumatic stress 3 to 6 months post-transfer (β = -.622, 95 % confidence interval -.640 to -.358) turned out to be

Phenolic compounds in Merlot wines from two wine regions of Rio Grande do Sul, Brazil

Carlos Eugenio Daudt

2013-06-01

Full Text Available In Brazil, the grape and wine production takes place mainly in the state of Rio Grande do Sul, and the region "Serra" is known as the traditional wine region. In the last years, new areas have emerged, with emphasis for the Campanha region; the red wines from this region have low acidity, little color intensity, and are wines to drink while young, even when produced from grape varieties such as Merlot and Cabernet Sauvignon. The objective of this study was to evaluate the influence of different maceration types on the phenolic compounds of Merlot wines made with grapes produced in two regions of Rio Grande do Sul, Serra and Campanha, as well as to identify the key differences between the wines produced. The localization of the vineyards seems to have more influence on the wine characteristics than the maceration type. The color due copigmentation was an important aspect in the wines made with short maceration. The effect of extended maceration was different than the expected for the Campanha region wines; the extended maceration increased the extraction of tannins resulting in greater color intensity and a greater amount of anthocyanins. The pH control seems to be a key factor for the Campanha region wines.

Passerina del Frusinate is an autochthonous wine grape variety, which grows in the Lazio region that is currently being evaluated by local wine producers. In this study, colour properties (CIELab coordinates), bioactive compounds (total polyphenols and flavan-3-ols), HPLC-DAD phenolic acid profiles and in vitro biological activity of monovarietal Passerina del Frusinate white wines and the effect of different maceration times (0, 18 and 24 h) were evaluated based on these parameters. Results highlighted statistically significant differences for almost all analysed parameters due to a strong influence of the pre-fermentative skin contact time. The flavan content of macerated wines was six times higher than that of the control, while total polyphenols were 1.5 times higher. According to their phytochemical content, macerated wines showed the highest antiradical capacity tested by means of DPPH(•) and ABTS(+•) assays. Besides, prolonged maceration resulted in a reduction of CIELab coordinates as well as of the content of phenolic substances and antiradical capacity. Among the phenolic acids analysed, the most abundant were vanillic acid and caffeic acid; the latter proved to be the most susceptible to degradation as a result of prolonged maceration. Passerina del Frusinate appears as a phenol-rich white wine with a strong antioxidant potential similar to that of red wines.

Quality improvement and cost containment initiatives in health care increasingly involve interdisciplinary teams of providers. To understand organizational functioning, information is often needed from multiple members of a leadership team since no one person may have sufficient knowledge of all aspects of the organization. To minimize survey burden, it is ideal to ask unique questions of each member of the leadership team in areas of their expertise. However, this risks substantial missing data if all eligible members of the organization do not respond to the survey. Nursing home administrators (NHA) and directors of nursing (DoN) play important roles in the leadership of long-term care facilities. Surveys were administered to NHAs and DoNs from a random, nationally representative sample of U.S. nursing homes about the impact of state policies, market forces, and organizational factors that impact provider performance and residents' outcomes. Responses were obtained from a total of 2,686 facilities (response rate [RR] = 66.6%) in which at least one individual completed the questionnaire and 1,693 facilities (RR = 42.0%) in which both providers participated. No evidence of nonresponse bias was detected. A high-quality representative sample of two providers in a long-term care facility can be obtained. It is possible to optimize data collection by obtaining unique information about the organization from each provider while minimizing the number of items asked of each individual. However, sufficient resources must be available for follow-up to nonresponders with particular attention paid to lower resourced, lower quality facilities caring for higher acuity residents in highly competitive nursing home markets. © The Author(s) 2014.

Coping Strategies of Family Members of Hospitalized Psychiatric Patients

2011-01-01

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.

Co-ordinate regulation of cytokinin gene family members during flag leaf and reproductive development in wheat.

As the global population continues to expand, increasing yield in bread wheat is of critical importance as 20% of the world's food supply is sourced from this cereal. Several recent studies of the molecular basis of grain yield indicate that the cytokinins are a key factor in determining grain yield. In this study, cytokinin gene family members in bread wheat were isolated from four multigene families which regulate cytokinin synthesis and metabolism, the isopentenyl transferases (IPT), cytokinin oxidases (CKX), zeatin O-glucosyltransferases (ZOG), and β-glucosidases (GLU). As bread wheat is hexaploid, each gene family is also likely to be represented on the A, B and D genomes. By using a novel strategy of qRT-PCR with locus-specific primers shared among the three homoeologues of each family member, detailed expression profiles are provided of family members of these multigene families expressed during leaf, spike and seed development. The expression patterns of individual members of the IPT, CKX, ZOG, and GLU multigene families in wheat are shown to be tissue- and developmentally-specific. For instance, TaIPT2 and TaCKX1 were the most highly expressed family members during early seed development, with relative expression levels of up to 90- and 900-fold higher, respectively, than those in the lowest expressed samples. The expression of two cis-ZOG genes was sharply increased in older leaves, while an extremely high mRNA level of TaGLU1-1 was detected in young leaves. Key genes with tissue- and developmentally-specific expression have been identified which would be prime targets for genetic manipulation towards yield improvement in bread wheat breeding programmes, utilising TILLING and MAS strategies.

[The role of university hospital executive board members].

Debatin, J F; Rehr, J

Demographic changes and medical progress in combination with vastly altered regulatory and economic environments have forced considerable change in the structure of German university hospitals in recent years. These changes have affected medical care as well as research and medical school training. To allow for more flexibility and a higher level of reactivity to the changing environment German university hospitals were transferred from state agencies to independent corporate structures. All but one remains wholly owned by the respective state governments. The governing structure of these independent medical hospitals consists of an executive board, generally made up of a medical director, a financial director, a director for nursing, and the dean of the medical faculty. In most hospitals, the medical director serves as chief executive officer. The regulations governing the composition and responsibility of the members of the executive board differ from state to state. These differences do affect to some degree the interactive effectiveness of the members of the executive boards. Modalities that stress the overall responsibility for all board members seem to work better than those that define clear portfolio limits. Even more than organizational and regulatory differences, the effectiveness of the work of the executive boards is influenced by the personality of the board members themselves. Success appears to be a clear function of the willingness of all members to work together.

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)
