    Quinones are essential building blocks of respiration, a universal process dedicated to efficient harvesting of environmental energy and its conversion into a transmembrane chemiosmotic potential. Quinones differentiate mostly by their midpoint redox potential. As such, ?-proteobacteria such as Escherichia coli are characterized by the presence of demethylmenaquinone (DMK) with an intermediate redox potential between low-potential (menaquinone) and high-potential (ubiquinone) quinones. In this study, we show that demethylmenaquinol (DMKH2) is a good substrate for nitrate reductase A (NarGHI) in nitrate respiration in E. coli. Kinetic studies performed with quinol analogs on NarGHI show that removal of the methyl group on the naphthoquinol ring impacts modestly the catalytic constant but not the KM. EPR-monitored redox titrations of NarGHI-enriched membrane vesicles reveal that endogeneous demethylmenasemiquinone (DMSK) intermediates are stabilized in the enzyme. The measured midpoint potential of the DMK/DMKH2 redox couple in NarGHI (E'm,7.5 (DMK/DMKH2) ~-70mV) is significantly lower than that previously measured for unbound species. High resolution pulsed EPR experiments demonstrate that DMSK are formed within the NarGHI quinol oxidation site. Overall, our results provide the first characterization of a protein-bound DMSK and allows for comparison for distinct use of three quinones at a single Q-site in NarGHI. PMID:25976528

    In this work, we evaluate the reliability of GHI and DNI forecast based on the WRF mesoscale atmospheric model in Andalusia (Southern Spain). Particularly, the role of the spatial resolution of the model set up and the use of a spatial-averaging post-processing step was analyzed. To this end, a set of two-days-ahead one-year-length integrations, with different spatial resolutions (1, 3, 9 and 27 km) were evaluated. Results showed, firstly, that an increment in the spatial resolution does not enhance the reliability of the model forecasts, except under clear sky conditions. Secondly, that, in general, an spatial averaging of the solar forecasts corresponding to the grid points surrounding the location of interest provides a notable improvement in the forecasting skills. The most significant improvement is found when forecasts corresponding to an area of about 100 by 100 km are averaged. The role of the WRF model cloud representation in the former results is discussed. (orig.)

    Full Text Available In this study, the acute effects of copper (CuSO4.5H2O on the expression of Growth Hormone-I (GH-I and Insulin like Growth Factors I and II (IGF-I and IGF-II were investigated in rainbow trout (Oncorhynchus mykiss muscle tissue. For this purpose, rainbow trout were exposed to 100 ?g L-1 (Sublethal concentration copper sulfate in moderately hard freshwater. After 6, 12, 24 and 48 h of treatment, expression of white muscle GH-I, IGF-I and IGF-II mRNAs were measured by means of quantitative real-time PCR. During the exposure experiments, no mortalities occurred. All mRNA levels significantly decreased after copper administration (p<0.05. The results indicate that short term copper exposure suppresses the mRNA expression levels of GH-I, IGF-I and IGF-II in rainbow trout muscles.

    2004-01-01

    The Gram-positive soil bacterium Bacillus subtilis transports glucose by the phosphotransferase system. The genes for this system are encoded in the ptsGHI operon. The expression of this operon is controlled at the level of transcript elongation by a protein-dependent riboswitch. In the absence of glucose a transcriptional terminator prevents elongation into the structural genes. In the presence of glucose, the GlcT protein is activated and binds and stabilizes an alternative RNA structure th...

  9. Preliminary bioelectrical impedance analysis (BIA) equation for body composition assessment in young females from Colombia

    International Nuclear Information System (INIS)

    A previous study showed that reported BIA equations for body composition are not suitable for Colombian population. The purpose of this study was to develop and validate a preliminary BIA equation for body composition assessment in young females from Colombia, using hydrodensitometry as reference method. A sample of 30 young females was evaluated. Inclusion and exclusion criteria were defined to minimize the variability of BIA. Height, weight, BIA, residual lung volume (RV) and underwater weight (UWW) were measured. A preliminary BIA equation was developed (r2 = 0.72, SEE = 2.48 kg) by stepwise multiple regression with fat-free mass (FFM) as dependent variable and weight, height and impedance measurements as independent variables. The quality of regression was evaluated and a cross-validation against 50% of sample confirmed that results obtained with the preliminary BIA equation is interchangeable with results obtained with hydrodensitometry (r2 = 0.84, SEE = 2.62 kg). The preliminary BIA equation can be used for body composition assessment in young females from Colombia until a definitive equation is developed. The next step will be increasing the sample, including a second reference method, as deuterium oxide dilution (D2O), and using multi-frequency BIA (MF-BIA). It would also be desirable to develop equations for males and other ethnic groups in Colombia.

  10. Highly Soluble Benzo[ghi]perylenetriimide Derivatives: Stable and Air-Insensitive Electron Acceptors for Artificial Photosynthesis

    2015-01-01

    A series of new benzo[ghi]perylenetriimide (BPTI) derivatives has been synthesized and characterized. These remarkably soluble BPTI derivatives show strong optical absorption in the range of ?=300–500 nm and have a high triplet-state energy of 1.67 eV. A cyanophenyl substituent renders BPTI such a strong electron acceptor (Ered=?0.11 V vs. the normal hydrogen electrode) that electron-trapping reactions with O2 and H2O do not occur. The BPTI radical anion on a fluorine-doped tin oxide|TiO2 electrode is persistent up to tens of seconds (t1/2=39 s) in air-saturated buffer solution. As a result of favorable packing, theoretical electron mobilities (10?2?10?1 cm2 V?1 s?1) are high and similar to the experimental values observed for perylene diimide and C60 derivatives. Our studies show the potential of the cyanophenyl-modified BPTI compounds as electron acceptors in devices for artificial photosynthesis in water splitting that are also very promising nonfullerene electron-transport materials for organic solar cells.

    Caicedo-Eraso, J. C.; Gonzalez-Correa, C. A.; Gonzalez-Correa, C. H.

    2013-04-01

    Several studies have shown that the accuracy of BIA results depends of ethnicity, age, gender, hormonal and genetic variations and, so far, there are not specific equations for Colombian population. The purpose was to evaluate reported BIA equations to determine their usefulness in body composition assessment in young females from Colombia using hydrodensitometry as the reference method. A sample of 30 young females was evaluated. Inclusion and exclusion criteria were defined to minimize the variability of BIA. Height, weight, multi-frequency BIA, residual lung volume (RV) and underwater weight (UWW) were measured. Five BIA equations met the inclusion criteria of this study. Three equations overestimated and two equations underestimated body fat (BF). Paired Student t-test and Bland and Altman analysis (p<0.05) showed significant differences in four BIA equations. However, all standard error of estimate (SEE) to BF was greater than 2.7 kg. This study showed that the five selected BIA equations are not valid for estimation of body composition in young females from Colombia. It is recommended to develop BIA equations to improve BF fat assessment in our population.

    We have used site-directed mutagenesis, EPR spectroscopy, redox potentiometry, and protein crystallography to monitor assembly of the FS0 [4Fe-4S] cluster and molybdo-bis(pyranopterin guanine dinucleotide) cofactor (Mo-bisPGD) of the Escherichia coli nitrate reductase A (NarGHI) catalytic subunit (NarG). Cys and Ser mutants of NarG-His49 both lack catalytic activity, with only the former assembling FS0 and Mo-bisPGD. Importantly, both prosthetic groups are absent in the NarG-H49S mutant. EPR spectroscopy of the Cys mutant reveals that the Em value of the FS0 cluster is decreased by at least 500 mV, preventing its participation in electron transfer to the Mo-bisPGD cofactor. To demonstrate that decreasing the FS0 cluster Em results in decreased enzyme activity, we mutated a critical Arg residue (NarG-Arg94) in the vicinity of FS0 to a Ser residue. In this case, the Em of FS0 is decreased by 115 mV, with a concomitant decrease in enzyme turnover to ?30% of the wild type. Analysis of the structure of the NarG-H49S mutant reveals two important aspects of NarGHI maturation: (i) apomolybdo-NarGHI is able to bind GDP moieties at their respective P and Q sites in the absence of the Mo-bisPGD cofactor, and (ii) a critical segment of residues in NarG, 49HGVNCTG55, must be correctly positioned to ensure holoenzyme maturation.

    2008-12-01

    This study was aimed at investigating the outcomes of an activity-based assessment (BIA) compared with standard assessment (SA) for evaluating clients undergoing psychiatric occupational therapy. Patients admitted to a psychiatric occupational therapy unit were randomized into the BIA or the SA assessment. The outcome indicators were (a) clients' satisfaction with the occupational therapy during the assessment period, (b) clients' awareness of capacities and occupational problems, (c) satisfaction with the assessment among the referring physicians, and (d) outcomes of the intervention following the assessment, in terms of changes in occupational performance and satisfaction. The groups did not differ in awareness of occupational problems, but the BIA group was more satisfied than the SA group with the support of their contact person and with the group leader during the period of assessment. Furthermore, physicians receiving feedback on patients in the BIA group were more satisfied than those receiving feedback on patients in the SA group. However, the groups did not differ concerning change during the treatment period in occupational performance or satisfaction. Thus, there was no difference between the assessment methods regarding the outcomes of the treatment following assessment. Minor advantages from the patients' perspective were found, in terms of better satisfaction in the BIA group, and from the referring physicians' perspective the BIA clearly seemed more satisfying than the SA. Thus, the findings showed that the BIA possessed better qualities than the SA regarding the indicators pertaining to satisfaction, but not concerning awareness of capacities and problems or the outcome of the subsequent treatment.

  1. Bioelectrical impedance analysis (BIA): a proposal for standardization of the classical method in adults

    International Nuclear Information System (INIS)

    The accuracy of BIA measurements is limited by different sources of error such as physical model, cross sectional area, ethnicity, body hydration, age and level of body fat among other variables. Equation for each population is required as they can produce overestimation when manufacturer's equations are used. The classical measurements hand to foot has shown better correlation against hydrodensitometry than foot to foot or hand to hand. However there is a lack for an accepted standard of BIA procedures. This is compounded when there is not a good report of the BIA study's methodology; hence the comparability between the results is poor and reduces the reliability of the method. Perhaps, standardization of methods would be the first step for BIA studies to move forward and subsequently improve its accuracy. Standardized procedures could also minimize the impact of these variables on studies results. The aim of this study was to propose a protocol as a checklist to standardize BIA procedures and produce comparable results from future studies performed with the classic hand-foot configuration in adults.

    Directory of Open Access Journals (Sweden)

    Halina Chomutowska

    2015-03-01

    Full Text Available Bia?owieza Forest is the natural habitat of many rare species of green plants, animals and fungi. For centuries, it has been a unique place for developing environmental processes. The water ponds are the wildlife habitat for many organisms, whose lives depend on aquatic environments. Protected species of green plants and animals also live in the water ponds. The aim of this research was to determine the species and quantity of plankton which are present in Bia?owieza Forest’s water ponds. The presence of different species of plankton proved the presence of minimal organic pollution. It was noticed that the primary producers dominated over the other organisms, which confirmed high mineralisation. The water ponds should continue to be monitored, as they are responsible for biodiversity within the Bia?owieza Forest area and they are the best place to settle for many species which are characteristic for swamps and small sources of water.

O paciente apresentado possuía características clínicas típicas de pacientes com IGH e em idade pré-púber [...] e seus achados laboratoriais eram compatíveis com este diagnóstico (IGF-1 e IGFBP3 baixos, GH basal e pós-estímulo elevados). No entanto, quando avaliado durante a puberdade, as dosagens de IGF-1 e IGFBP-3 foram normais, dificultando o diagnóstico. O estudo molecular identificou mutação no exon 7 do gene do receptor do hormônio de crescimento (S226I). Discutiram-se os passos realizados para identificar a mutação e demonstrar que ela é responsável pelo fenótipo observado no paciente. Também será feita revisão dos casos de IGH descritos no Brasil e dos novos defeitos moleculares descritos nesta doença. Abstract in english It is reported in this study the clinical, laboratory and genetic aspects of short stature investigation with emphasis to the diagnostic approach of growth hormone insensitivity (GHI). This patient in case presented typical clinical features of GHI and his laboratory findings at prepubertal age were [...] typical of those observed in GHI patients (low IGF-1 and IGFBP-3 levels, with high basal and stimulated GH levels). However, during the puberty, he presented normal IGFBP-3 and IGF-1 levels that hindered the diagnosis. The molecular study disclosed a mutation in exon 7 of growth hormone receptor gene (S226I). The steps that demonstrated the causative effect of this mutation are shown here, and also a review of Brazilian GHI cases is given and new molecular defects in this field are discussed as well.

    Full Text Available The Bia?a Tarnowska River is a right-bank tributary of Dunajec. It flows from the Low Beskid Mountains, flowing on the border of Ci??kowickie and Ro?nowskie foothills and then flows into the Dunajec on the territory of Vistula Lowland (Nizina Nadwi?la?ska. The aim of this work was to investigate the diatoms diversity at the individual sites and attempt to evaluate pollution of the river with the use diatoms as water quality indicators. The waters of Bia?a Tarnowska River were characterized by alkaline or circumneutral pH. Values of nitrates concentration indicated II water quality class, only at the last site (5 corresponded to the standards for the I class. At the studied sites located along river course 205 diatom taxa were identified. The riches in species were genera: Nitzschia (29, Navicula (21 and Gomphonema (15. The most popular dominant was Achnanthidium pyrenaicum (Hust. Kobayasi. Very numerous communities were created by Navicula lanceolata (Agardh Kütz, at the lower current of river, on two last sites. In order to determine the ecological status of Bia?a Tarnowska River the analysis of the diatom assemblages structure was performed. The results of the analysis were shown by the selected diatomaceous indices. According to IPS index Bia?a Tarnowska has a good ecological status (II class at the most of study sites. Values of TDI index were the worst and indicated poor and bad water quality (IV and V class especially in middle and lower current.

    Full Text Available Abstract Background Body composition analysis using phase angle (PA, determined by bioelectrical impedance analysis (BIA, reflects tissue electrical properties and has prognostic value in liver cirrhosis. Objective of this prospective study was to investigate clinical use and prognostic value of BIA-derived phase angle and alterations in body composition for hepatitis C infection (HCV following antiviral therapy. Methods 37 consecutive patients with HCV infection were enrolled, BIA was performed, and PA was calculated from each pair of measurements. 22 HCV genotype 3 patients treated for 24 weeks and 15 genotype 1 patients treated for 48 weeks, were examined before and after antiviral treatment and compared to 10 untreated HCV patients at 0, 24, and 48 weeks. Basic laboratory data were correlated to body composition alterations. Results Significant reduction in body fat (BF: 24.2 ± 6.7 kg vs. 19.9 ± 6.6 kg, genotype1; 15.4 ± 10.9 kg vs. 13.2 ± 12.1 kg, genotype 3 and body cell mass (BCM: 27.3 ± 6.8 kg vs. 24.3 ± 7.2 kg, genotype1; 27.7 ± 8.8 kg vs. 24.6 ± 7.6 kg, genotype 3 was found following treatment. PA in genotype 3 patients was significantly lowered after antiviral treatment compared to initial measurements (5.9 ± 0.7° vs. 5.4 ± 0.8°. Total body water (TBW was significantly decreased in treated patients with genotype 1 (41.4 ± 7.9 l vs. 40.8 ± 9.5 l. PA reduction was accompanied by flu-like syndromes, whereas TBW decline was more frequently associated with fatigue and cephalgia. Discussion BIA offers a sophisticated analysis of body composition including BF, BCM, and TBW for HCV patients following antiviral regimens. PA reduction was associated with increased adverse effects of the antiviral therapy allowing a more dynamic therapy application.

    Full Text Available According to the regulations of the Polish Ministry of Science and Higher Education, university graduates should have to know a foreign language at B2 level, as described in The Common European Framework of Reference, and they should know its specialized variety. These are the only recommendations concerning general language courses and their specialized varieties. It is up to schools of foreign languages or other institutions providing language courses for institutions of higher education to determine requirements concerning language for specific purposes. However, students are rarely asked to contribute to the development of curricula and syllabi. This article presents the results of a survey conducted among students of Economics and Management at the University of Bia?ystok. The survey was devoted to students’ perceptions of Business English in English courses conducted by the School of Foreign Languages at the University of Bia?ystok. The aim of the survey was to answer the following questions:

  19. Density, degeneracy, delocalization-based index of aromaticity (D3BIA)

    Full Text Available A aromaticidade tem sido exaustivamente discutida e continua sendo um tema misterioso. Nesse trabalho é proposto um novo índice de aromaticidade chamado índice baseado na densidade-degenerescência-deslocalização ou, simplesmente, D3BIA, numa tentativa de lançar nova introspecção sobre esse tema. Ess [...] e índice é baseado na teoria de átomos em moléculas (AIM) e, de certa forma, é suportado pela teoria dos spins acoplandos (SC). A aromaticidade diminui com o número de heteroátomos na molécula aromática, pois a degenerescência diminui, e diminui com o aumento do tamanho do anel do composto aromático porque desfavorece a sobreposição dos estados monoeletrônicos. A relação entre planaridade do anel, sua densidade eletrônica e aromaticidade é também observada. A interação atrativa da ressonância de 6 elétrons pi no diânion ciclobutadieno compensa sua interação repulsiva carbono-carbono enquanto no seu parente dicatiônico a ressonância de 2 elétrons pi é insuficiente para contrabalancear sua interação repulsiva e adota uma estrutura não-plana. Abstract in english Aromaticity has been exhaustedly discussed for several years and it remains as a misterious issue. In this work it is proposed a new index of aromaticity named density, degeneracy and delocalization-based index of aromaticity or simply D3BIA in an attempt to cast new insight and perspective over thi [...] s theme. This index is based on AIM (atoms in molecules) theory and it is somewhat supported by SC (spin-coupled) theory. Aromaticity decreases as the number of heteroatoms in the aromatic molecule increases since degeneracy decreases and it decreases as the ring size of an aromatic compound increases because it disfavors overlap of single-electron states. The relation between planar structures, electron density and aromaticity is also observed. The attractive interaction of 6pi-electron resonance in cyclobutadiene dianion compensate its carbon-to-carbon repulsive interaction while in its dicationic parent the 2pi-electron resonance is insufficient to counterbalance its carbon-to-carbon repulsive interaction and it adopts a puckered structure.

  20. Baltic Sea coastal erosion; a case study from the Jastrz?bia Góra region

    The coastline in the Jastrz?bia Góra area can be divided into three major zones of general importance: a beach and barrier section, a cliff section, and a section protected by a heavy hydrotechnical construction. These areas are characterised by a diverse geology and origin, and hence different vulnerability to erosion. In addition, observations have demonstrated a different pace of erosion within each zone. Based on the results obtained by remote sensing methods (analysis of aerial photographs and maps), it has been determined that the coastline in the barrier area, i.e., to the west of Jastrz?bia Góra, moved landwards by about 130 m, in a period of 100 years, and 80 m over about 50 years. A smaller displacement of the shoreline could be observed within the cliff. Between the middle of the twentieth and the start of the twenty-first centuries the shore retreated by about 25 m. However, in recent years, an active landslide has led to the displacement of the uppermost part of the cliff locally up to 25 m. Another issue is, functioning since 2000, a heavy hydrotechnical construction which has been built in order to protect the most active part of the cliff. The construction is not stable and its western part, over a distance of 50 m, has moved almost 2 m vertically downwards and c. 2.5 m horizontally towards the sea in the past two years. This illustrates that the erosional factor does not comprise only marine abrasion, but also involves land-based processes determined by geology and hydrogeology. Changes in the shoreline at the beach and barrier part are constantly conditioned by rising sea levels, the slightly sloping profile of the sea floor and low elevation values of the backshore and dune areas. Cliffs are destroyed by mass wasting and repetitive storm surges that are responsible for the removal of the colluvium which protects the coast from adverse wave effects. Presumably, mass movements combined with groundwater outflow from the cliff, plus sea abrasion cause destabilisation of the cliff protection construction.

    Full Text Available The aim of the study was to analyze the species composition of the dendroflora near four main roads in the city of Bia?ystok, taking into regard their geographical and historical origin. The wildlife inventory was conducted in the vegetation season of 2011. The inventory revealed presence of a total of 837 trees and bushes representing 36 species and 18 families. The most abundant trees were those from the family Aceraceae (63.8%, while the most abundant bushes were those representing Rosaceae (48.9%. The contribution of native species (65.7% was found to be about twice as high as that of alien ones (34.3%. The dominant species among the native trees was Acer platanoides L., while the principal bush species was Crataegus monogyna Jacq. The alien tree species were most commonly represented by Acer negundo L., and bushes - by Ligustrum vulgare L. Spontaneously settled trees and bushes were clearly dominant (59.9% over those originating from plantations (40.1%. Among the native species of local origin, the prevailing species were synanthropic spontaneophytes (52%, including Acer platanoides and Tilia cordata Mill. Anthropophytes were more abundantly represented by diaphytes (22.7%, followed by kenophytes (10.4%. The most abundant species among diaphytes was Ligustrum vulgare, and among kenophytes - Acer negundo.

  4. Bioelectrical impedance analysis (BIA) for sarcopenic obesity (SO) diagnosis in young female subjects

    International Nuclear Information System (INIS)

    Sarcopenia is defined as a loss of muscle mass depending of ageing and affecting physical function (definition A). A new definition considers excluding mass reduction criterion (definition B). Obesity is pandemic and occurs at all ages. Sarcopenic obesity (SO) implies both processes. The purpose of this study was to compare the results obtained after applying these 2 definitions in 66 aged 22 ± 2.8 years overweight or obese young college women. Percentage body fat (%BF) and skeletal mass index (SMI) were estimated by BIA, muscle function by handgrip strength test (HGS) and physical performance by Harvard step test (HST). There were 9.1% and 90.9% overweight or obese subjects. Twenty nine subjects (43.9%) had decreased HGS and 22 (33.3%) had impaired physical performance. One obese subject (1.5%) met the criteria for sarcopenic obesity by definition A and 9 (13.6%) by definition B. Although a linear regression (? 2 = 0.094, 0.037 and 0.275 respectively) it was observed a tendency for HGS, HST and SMI deterioration when %BF increases. However, other confounding factors must be investigated. Probably as the population gets more obese, the problematic of SO will be found earlier in life.

    Full Text Available The ‘Tisovik’reserve, located in the Belarusian part of the Bia?owie?a Forest, holds an isolated relic stand of silver fir, situated 120 km to the north-east of the main forest. In order to preserve this relic fir stand, a ancestral conservative tillage consisting of the Jd 92 trial (plot I and the Jd 94 trial (plots II and III was established between 1992 and 1994 in the Polish part of the Bia?owie?a Forest on the territory of the Hajnówka Forest District. The growth and development of the progeny of 20 firs were characterized by means of long-term observations made in these trials. In 2000 (at the age of 18, the firs in the Jd 92 trial (plot I reached an average height of 394.86 cm with a mean diameter at breast height of 42.42 mm and the average rate of survival amounted to 75%. In the Jd 94 trial, the rate of fir survival on plot II was 70% (at the age of 15 with an average height of 277.08 cm and a diameter at breast height of 36.62 mm, while on plot III only 50 trees with an average height of 198.6 cm and a diameter at breast height of 24.49 mm survived. The results of this study show that the fir progeny in the ‘Tisovik’ reserve is of high breeding value. Therefore, the silver fir seed stock of the ‘Tisovik’ reserve is suitable for the establishment of new plantations in the Polish part of the Bia?owie?a Forest and the Mazury-Podlasie Region.

    The Bureau of Indian Affairs (BIA) is responsible for the natural resource management of approximately 52 million acres of Trust lands in the contiguous United States. The lands are distributed in a "patchwork" fashion throughout the country. Management responsibilities on these areas include: minerals, range, timber, fish and wildlife, agricultural, cultural, and archaeological resources. In an age of decreasing natural resources and increasing natural resource values, effective multiple resource management is critical. BIA has adopted a "systems approach" to natural resource management which utilizes Geographic Information System (GIS) technology. The GIS encompasses a continuum of spatial and relational data elements, and included functional capabilities such as: data collection, data entry, data base development, data analysis, data base management, display, and report generalization. In support of database development activities, BIA and BLM/TGS conducted a cooperative effort to investigate the potential of 1:100,000 scale Thematic Mapper (TM) False Color Composites (FCCs) for providing vegetation information suitable for input to the GIS and to later be incorporated as a generalized Bureau wide land cover map. Land cover information is critical as the majority of reservations currently have no land cover information in either map or digital form. This poster outlines an approach which includes the manual interpretation of land cover using TM FCCs, the digitizing of interpreted polygons, and the editing of digital data, used upon ground truthing exercises. An efficient and cost-effective methodology for generating large area land cover information is illustrated for the Mineral Strip area on the San Carlos Indian Reservation in Arizona. Techniques which capitalize on the knowledge of the local natural resources professionals, while minimizing machine processing requirements, are suggested.

    The European bison is the largest terrestrial mammal in Europe. After extinction in the wild at the beginning of the twentieth century, it was re-introduced to Bia?owie?a Forest and other woodlands in Eastern Europe. In this paper, we analysed the movements of European bison beyond the continuous woodlands of the Bia?owie?a Forest (NE Poland) between 1964 and 2010. In total, 1,117 direct observations of bison were collected. The number of males moving out of the forest fluctuated during the study period, whilst the number of females steadily increased. The number of male observations outside of the forest per annum was dependent on the population size and snow depth, whilst the number of cows in mixed groups moving outside of the forest was correlated with the population size only. Males were observed mainly alone (50 % of observations) or in small groups of two to three individuals (25 %); however, distribution of group size differed from those observed in the population. There was a significant difference between the direction of movement of males and females out of the forest-males moved mainly west and southwest, whilst females moved to the north. This was also significantly different from the expected movement direction. The mean distance of bison observations from the forest border was 1.8?±?0.13 km and did not differ significantly between sexes. After 1990, males were observed significantly farther away from the forest (2.2 km) than in the previous years (0.9 km). Most observations (94 % of bulls and 93 % of cows) were up to 5 km from the forest edge. The range of bison in the vicinity of the Bia?owie?a Forest was strictly seasonal. Most observations (78 % in males and 88 % in females) were recorded from November to April. Increasing utilisation of areas beyond the forest habitats may be driven by different factors but most probably it is related to range expansion and the bison's preference for open habitats. The strong seasonal pattern of bison movements indicate that the partial seasonal migrations were initiated in the Bia?owie?a population. PMID:24244043

    Full Text Available During geobotanical studies in the north-eastern border of hemi-boreal zone, in Valday (NW Russia, rare eutrophic deciduous forests dominated by oak Quercus robur were observed. A comparison of these forests with the model of European deciduous forest in Bia?owie?a National Park (NE-Poland indicates a great similarity. Therefore, eutrophic deciduous forests in Valday can be classified to the Querco-Fagetea class, the Fagetalia sylvaticae order and to the Capinion betuli alliance, despite the absence of hornbeam Carpinus betulus in the region. Rarity of eutrophic deciduous forests in Valday region results probably from strong anthropogenic pressure in the past.

    Full Text Available The process of pigs producer groups formation in Poland is quite dynamic. Currently on the pork market 181 groups operate, which includes about 4000 swine producers. The aim of this study was to characterize the activities of the Agricultural Producers Association in Bia?a District. The research tool was a personal questionnaire and the research sample consisted of 30 farmers. It has been shown that after joining the producers group, the investigated households reported an increase in sales volume and improved the flock production parameters. Majority of the respondents were not satisfied with the cooperation with meat processing companies.

    We analyzed habitat requirements of Boros schneideri (Panzer, 1796) (Coleoptera: Boridae) in the natural forests of the continental biogeographical region, using data collected in the Bia?owie?a Forest. This species has been found on the six host trees, but it preferred dead, standing pine trees, characterized by large diameter, moderately moist and moist phloem but avoided trees in sunny locations. It occurred mostly in mesic and wet coniferous forests. This species demonstrated preferences for old tree stands (over 140-yr old), and its occurrence in younger tree-stand age classes (minimum 31-40-yr old) was not significantly different from random distribution. B. schneideri occupied more frequently locations distant from the forest edge, which were less affected by logging. Considering habitat requirements, character of occurrence, and decreasing number of occupied locations in the whole range of distribution, this species can be treated as relict of primeval forests.

    Full Text Available In Bia?owie?a Primeval Forest, in 1823 Stanis?aw Górski discovered on the Cisovka Hag, a relic population of European silver-fir (Abies alba Mill.. This population is isolated and most away, 120 km to the North-East, from the border of European-silver-fir distribution. Besides the natural population Cisovka, there are also man-made silver fir stands and clumps in the Polish and Belorussian part of Bia?owie?a Primeval Forest. In the Polish part there are four such artificial stands. If the seed-producing silver-fir stands really originated from the Cisovka population, then they are a very valuable part of the declining population and an easy accessible seed source. However, if these populations were introduced to the Bia?owie?a Primeval Forest, then they are a potential source of dangerous genetic pollution of the Cisovka population. The relationship of the genetic structure of the Cisovka population to man-made silver-fir-stands in Bia?owie?a Forest was investigated with the help of 17 loci of 1 1 enzyme systems. Genetic diversity of Cisovka population is characterized by the smallest mean number of alleles per locus (Mal= 1.353, includes all loci studied and per polimorphic locus Malp = 2.00. In Cisovka population there is very low-grade of polimorphic loci (Pp = 11.765 with the mean 37.255 for all studied populations. Expected heterozygosity, He = 0.079 revealed very low-grade of genetic diversity in the population. The observed heterozygosity (Ho = 0.123 was similar to this characterictic in other populations. A dendrogram based on Neis genetic distance coefficient (D among 9 silver-fir populations was constructed. Cisovka in the UPGMA dendrogram is a distinct population separated from other ones by a very great genetic distance (D = 0.06. Also two man-made silver-fir (B I and 132 stands are separated from others. Only populations B3 and B4 are combined into one subgroup linked to the population Tomaszów Lubelski. Basing on the received results one should decide that all the four studied artificial stands were introduced to Bia?owie?a Primeval Forest from beyond of this geographical regions. There is some reason to assume (on the GDH2 allele frequency that man-made silver-stands in compartments 453Aa and 498Cg are of eastern provenance. It is rather certain that these stands are not of offspring of Cisovka populations.

    Full Text Available Elements of the Belarusian language in the Russian dialect used by the Old Believers living in the Suwa?ki-Augustów regionThe article deals with the Belarusian elements in the Russian dialect of the Old Believers living in Poland. The Old Believers arrived in Poland in the second half of the 18th century. At present they live in the Suwa?ki-Augustów region in the north-eastern Poland. They inhabit mostly two villages in the county of Suwa?ki, namely Gabowe Gr?dy and Bór, which are very close to each other, and three towns: Augustów, Suwa?ki and Sejny. The dialect used by the Polish Old Believers represents the western Central Great Russian dialects characterized by akanie, the so-called Pskov group. They share features which are typical of Pskov. The dialect was also influenced by other north-eastern Belarusian dialects, that is, the ones which were closest to the areas originally inhabited by Old Believers, who migrated in phases. After each phase, their dialect came to reflect some new linguistic influences. A large number of lexemes directly borrowed from Polish, or via the Belarusian language, are found in this dialect, which is also characterized by other features common in Belarusian dialects or the Bulgarian language. By way of illustration, they include the following features: the prosthetic j-, prosthetic v-, the occurrence of the endings –im and –ym in the case of singular masculine adjectives in the locative, promotion of the endings –i and –y in the case of the plural masculine and neutral nouns in the nominative, and the occurrence of lexemes borrowed from the Belarusian language. Bia?oruskie elementy j?zykowe w rosyjskiej gwarze staroobrz?dowców mieszkaj?cych w regionie suwalsko-augustowskimArtyku? po?wi?cony jest problematyce bia?oruskich elementów j?zykowych w rosyjskiej gwarze staroobrz?dowców mieszkaj?cych w Polsce.

    1.?The disposition etamicastat was evaluated in the Cynomolgus monkey after intravenous and oral administration of [(14)C]-etamicastat. The pharmacokinetics of etamicastat and its N-acetylated metabolite BIA 5-961 were also evaluated in monkeys and dogs. 2.?In the monkey, 7 days after intravenous and oral administration of [(14)C]-etamicastat, 76.6-91.1% of the etamicastat-related radioactivity had been excreted mainly in urine. The radioactivity peaked in plasma between 4- and 8-h post-dosing followed by a quick decline and a slow terminal phase (half-life of 68.7?h). The calculated oral bioavailability for etamicastat was 46.1%. Etamicastat was quickly absorbed in monkeys and dogs with a half-life ranging from 5.2 to 9.9?h in monkeys and 6.9 to 11.4?h in dogs over. 3.?The N-acetylated metabolite of etamicastat, represented 4-7% of the extent of exposure of etamicastat in the monkey, but was not found detectable in dogs. Gender did not influence etamicastat exposure and the concentration versus time curves fitted a dose-dependent pharmacokinetics in the dog, but not in the monkey. 4.?In conclusion, etamicastat is rapidly absorbed and primarily excreted via urine in monkeys. Similarly, to humans, monkeys, unlike dogs, N-acetylate etamicastat and evidence that etamicastat pharmacokinetics is less than dose proportional. PMID:25869244

    Studies of fungi and fungus- like organisms in the northeastern Poland have mainly concentrated on running waters in the vicinity of Bia?ystok, including the Horodnianka River. The main objective was to investigate biodiversity of fungi and fungus-like organisms which take part in decomposition of organic matter commonly found in inland waters. To obtain a complete picture of species composition of fungi and fungus-like organisms in running waters we decided to explore representative sites of the Horodnianka River such as Olmonty, Hryniewicze and Horodniany with close localization of landfill. Fungal species were isolated using baiting technique. Baits of onion skin (Alium cepa), hemp-seeds (Cannabis sativa), impregnated cellophane and snake skin (Natrix natrix) were applied to isolate fungi from water of the Horodnianka River. The fungal community consists of 26 species, 10 species of fungi belonging to class Chytridiomycetes (3), anamorphic fungi (6), and Zygomycetes (1). 16 species belong to fungus-like organisms from class Oomycetes. Most of the recognized species have already been found in other running waters. From all the examined habitats the fungi belonging to 26 species of 18 genera Achlya, Alternaria, Aphanomyces, Aspergillus, Catenophlyctis, Dictyuchus, Fusarium, Karlingia, Lagenidium, Leptomitus, Olpidiopsis, Penicillium, Phlyctochytrium, Pythium, Saprolegnia, Scoliognia, Thraustotheca and Zoophagus were obtained. Certain fungal species like Aphanomyces laevis, Fusarium aqueductum, F. moniliforme, F. oxysporum, Leptomitus lacteus, Saprolegnia feax and S. parasitica were found at all the study sites. Among fungi potentially pathogenic and allergogenic for humans the genera Alternaria, Aspergillus, Fusarium, Lagenidium and Penicillium have already been described. However, the species Lagenidium giganteum and Achlya androgyna are new in the fungal biota of Poland. The greatest number of fungal species occurred in Olmonty (24), the smallest in Horodniany (13). Presence of fungi such as Leptomitus lacteus, Fusarium aqueductum in the water of the Horodnianka River offers the possibility of using them as indicators of water quality. PMID:22165737

    Highlights: • [Fe(PM-BIA){sub 2}(NCS){sub 2}] is identified in high and low spin states, showing spin crossover. • DFT studies provide charges and Morse potentials used in MD for orthorhombic phase. • DFT and MD simulations reproduce thermodynamics leading to enthalpy variation. • Spin crossover T{sub 1/2} calculated within range of experiment from enthalpies and structure. • Calculated (P, T) phase diagram shows monoclinic polymorph in two spin states. - Abstract: The spin crossover properties and the domains of existence of the different phases for the [Fe(PM-BIA){sub 2}(NCS){sub 2}] complex are obtained from combining DFT and classical molecular dynamics (MD). The potential energy surfaces expressed in the Morse form for Fe–N interactions are deduced from molecular DFT calculations and they allow producing Infra Red and Raman frequencies. These Fe–N potentials inserted in a classical force field lead from MD calculations to the relative energies of the high spin and low spin configurations of the orthorhombic structure. The MD investigations have also allowed assessing the experimental (P, T) phase diagram by showing the monoclinic polymorph in its two spin-states, and generating two triple points.

    In this paper the total concentration of As, Cr, Sb, pH and the red-ox potential of water and sediment samples of the Bia?a Przemsza River were determined. The arsenic (AB, MMA, DMA, As(III), As(V)), chromium (Cr(III), Cr(VI)) and antimony (Sb(III), Sb(V)) forms were studied by HPLC-ICP-MS. Ions were successfully separated on Hamilton PRP-X100: (AB, MMA, DMA, As(III), As(V)), Dionex Ion Pac AS-7 (Sb(III), Sb(V)) and Dionex IonPac AG7 columns: Cr(III), Cr(VI) with LOD 0.16 ?g/L, 0.08 ?g/L, 0.09 ?g/L, 0.012 ?g/L, 0.08 ?g/L, 0.12 ?g/L, 0.009 ?g/L, 0.012 ?g/L, 0.19 ?g/L, 0.37 ?g/L, respectively. The simplified BCR three-step sequential chemical extraction was performed on the bottom sediment samples. The samples were collected monthly, between April and December 2014, at five sampling points. Large contents of manganese, lead, cadmium and zinc were found in the Bia?a Przemsza River water. In December 2014, the lead content in the bottom sediment in S?awków was nearly 6000 mg/kg. In the river water, only the inorganic arsenic speciation forms were found. Sb(V), As(V) and Cr(III) were dominant. Studies have shown that arsenic, antimony and chromium were mainly bound to oxides, organic matter and sulphides in the bottom sediments. PMID:25941843

However, the understanding of participation is ambiguous and there are at least three major approaches, which may have different impacts on the governance of protected areas. We examine the case of the Bia?owie?a Primeval Forest in order to trace the effectiveness of changing modes of participation as well as to discuss the limitations and problems of public participation. Between 1918 and 2010, the role of local authorities changed from no influence to limited control over decision making regarding designation and enlargement of the Bia?owie?a National Park (BNP. As a result of these changes, attempts to enlarge the BNP over the whole forest were undermined. The evidence shows that power relations and instrumental reasons constituted the main drivers of the changing participation pattern with deliberative rationale lacking. As a result, the conservation goals were only partially achieved. We argue that when interests are clearly conflicting and win–win solutions are difficult to reach, room for constructive participation may be limited. In these circumstances, public involvement may turn into yet another venue for a power play between actors with vested interests, without bringing gains in legitimacy or new policy options. This is especially the case for countries with a relatively short democratic record where the government lacks the consistency and capacity to steer the process over the longer term.

    Full Text Available The study presents the analysis of the findings of 234 post-mortem examinations on free-ranging and captive European bison selectively culled or having fallen between 2008 and 2013 in Bia?owie?a Primeval Forest. Pneumonia, emphysema, nephritis, bodily traumas, and intestinal lesions were observed in 106 (45.3%, 77 (32.9%, 82 (35.0%, 68 (29.1%, and 56 (23.9% animals respectively and were the most common pathological changes. Almost half of all males (66 out of 140; 47.1% tested showed some pathological changes of prepuce and penis, described as posthitis or balanoposthitis. Infection with liver fluke (Fasciola hepatica and lungworm (Dictyocaulus viviparus was observed macroscopically in 114 (48.7% and 80 (32.9% bison respectively. F. hepatica prevalence was associated with the emergence of other liver changes such as hepatitis and cirrhosis (P < 0.001. Similarly, the prevalence of D. viviparus coincided with pneumonia (P = 0.001, changes in the upper respiratory tract (P = 0.04, and emphysema (P < 0.001. Hepatitis, infection with F. hepatica, and pathological lesions in the male and female reproductive tracts were associated with the animals’ age. Mechanical injuries, caused by other bison or less commonly by traffic accidents, were the most common cause of death of bison below six months of age. Most pathological changes were significantly more frequent in the selectively culled animals in comparison with the ones having fallen, which confirms the desirability of elimination as a tool to improve the health and welfare of the bison population and limit the number of reservoirs of invasive and possibly infectious diseases.

  6. The origin of the Avram Iancu U-Ni-Co-Bi-As mineralization, B?i?a (Bihor) metallogenic district, Bihor Mts., Romania

    The B?i?a metallogenic district in the Bihor Mountains is a historically important mining area in Romania. Uranium mining took place between 1952 and 1998 from various deposits, but very little is known about the geology and mineralogy of these deposits. In this paper, we describe geology and mineralogy of uranium mineralization of the Avram Iancu uranium mine from waste dump samples collected before complete remediation of the site. Texturally and mineralogically complex assemblages of nickeline, cobaltite-gersdorffite solid solution, native Bi, Bi-sulfosalts, molybdenite, and pyrite-chalcopyrite-sphalerite occur with uraninite, "pitchblende," and brannerite in most of the ore samples. The association of nickel, cobalt, and arsenic with uranium is reminiscent of five-element association of vein type U-Ni-Co-Bi-As deposits; however, the Avram Iancu ores appear to be more replacement-type stratiform/stratabound. Avram Iancu ore samples contain multistage complex, skarn, uranium sulfide, arsenide assemblages that can be interpreted to have been formed in the retrograde cooling stages of the skarn hydrothermal system. This mineralizing system may have built-up along Upper Cretaceous-Paleogene "Banatite" intrusions of diorite-to-granite composition. The intrusions crosscut the underlying uraniferous Permian formations in the stacked NW-verging Biharia Nappe System. The mineralization forms stacked, multilayer replacement horizons, along carbonate-rich lithologies within the metavolcanic (tuffaceous) Muncel Series. Mineral paragenesis and some mineral chemistry suggest moderate-to-high <450, i.e., 350-310 °C, formation temperatures for the uranium sulfide stage along stratigraphically controlled replacement zones and minor veins. Uranium minerals formed abundantly in this early stage and include botryoidal, sooty and euhedral uraninite, brannerite, and coffinite. Later and/or lower-temperature mineral assemblages include heterogeneous, complexly zoned arsenide-sulfarsenide solid solutions associated with minute but abundant uranium minerals. Within the later arsenide-sulfarsenide mineral assemblage, there is great variation in Ni, Co, and S content with generally increasing arsenic content. Uranium minerals in this late-stage assemblage include very fine euhedral uraninite and brannerite inclusions in arsenide-sulfarsenide minerals. Native bismuth and Bi-sulfosalt krupkaite are observed in this As-S-rich assemblage strongly associated with cobaltite.

To describe body composition, total body water and dry weight of patiens who suffer from renal disease and are under hemodialysis. Materials and methods. A transversal descriptive study was carried out by six phases from the year 2001 to 2010. It was used the Unifrequency Tetrapolar Bioimpedance (BIA-1), the Multifrequency Tetrapolar Bioimpedance (BIA-4) and the Ramírez-Almanza equation. Normovolemia and hipervolemia values were used to establish dry weight and a new instrument was used in nutritional diagnosis to global subjective valuation in renal patient under hemodialysis, the Malnutrition Inflammation Score (MIS). Results. 50% of the studied patients had a diabetes and hipertension diagnosis, 87% were in a low risk of desnutrition, just 3% without any risk of desnutrition. The Resistance cohort point given by the bioimpedance of 550 allows to determine who patients with values under of this are somatics with 73% a hight sensibility and a 50% specificity. To total water weight it is possible to use the Ramirez-Almanza equation due to it has a good mediana correlation (0.76) with the Kushner Impedance Index. VGS-MIS is the best assessment method used until know on renal patient because it involves different physic, nutritional, clinic and biochemic parameters. Conclusion. Bioimpedance use on patient under hemodialysis has led a higher precision in the total body water, dry weight and nutritional state in such patients.

    Full Text Available Esta investigación estudió las relaciones entre el uso y protección del bosque Bia?owie?a, Polonia, durante el último siglo, particularmente en las décadas de la post-guerra. Debido a los extraordinarios valores naturales, esta área necesita una protección muy especial. Sin embargo, se han observado [...] diversos impactos negativos sobre el paisaje. Los cambios implicaron perforación y fragmentación del bosque causados por la continua tala de árboles, debido a la expansión urbana asociada al desarrollo turístico. El objetivo de esta investigación fue identificar los forzantes subyacentes de tendencia negativa y los obstáculos para el progreso de la conservación de la naturaleza en la zona. Comparación de puntos de vista, visiones de uso del suelo y manejo del bosque, evidenciaron importantes diferencias en actitudes, perspectivas y expectativas aplicadas al bosque de Bia?owie?a. El estudio reveló la importancia de la dimensión socio-cultural en el estado actual de evolución del paisaje. Esta influencia está relacionada con una presión constante sobre la explotación maderera, por lo menos parcialmente, desde una fuerte posición de la administración forestal en esta área y desde visiones específicas de uso de suelo que enfatizan los servicios económicos de los bosques. Cabe destacar, que acciones realizadas en todo el país y los numerosos esfuerzos para ampliar las áreas de protección no han tenido éxito hasta el momento. Se argumenta que la subestimación de los valores naturales expresada por las comunidades locales, además de las debilidades de la legislación ambiental del Estado, pueden traer serias amenazas para el paisaje analizado y afectar a todo el sistema de conservación de la naturaleza en Polonia. Abstract in english The work concentrated on relations between the issues of use and protection that developed in the Polish part of the Bia?owie?a Forest last century, particularly during the post-war decades. Owing to extraordinary natural values, the area deserves very careful protection, however, negative impacts o [...] n the landscape have been widely observed. The changes involving perforation and fragmentation of forest cover caused by continuous logging are accompanied by spatial disorder in built areas and their vicinities resulting from tourism development. The aim of the research was to identify the underlying forces of negative tendencies and simultaneously, obstacles to progress in nature conservation of the area. Comparison of views and visions of land-use and management of the Forest showed that great differences in attitudes, applied perspectives and expectations to the Bia?owie?a Forest exist. The study revealed the importance of a socio-cultural dimension for a current stage of landscape evolution. This influence is connected with a steady pressure on wood exploitation and results, at least partially, from a strong position of forest administration in this area and from specific land-use visions emphasizing economic services of the forest. Noteworthy, actions undertaken across the country and numerous efforts to extend protection of the area have not succeeded so far. It is argued that underestimation of natural values expressed by local communities in addition to weaknesses of the state’s environmental law may bring serious hazards to the analysed landscape and affect the whole system of nature conservation in Poland.

    I will describe the methodology used to develop and deploy operationally a comprehensive solar forecasting system for both concentrated and non-concentrated solar technologies. This operational forecasting system ingests data from local telemetry, remote sensing and Numerical Weather Prediction (NWP) models, processes all the diferent types of data (time series, sky images, satellite images, gridded data, etc.) to produce concatenated solar forecasts from 5 minutes out to 72 hours into the future. Each forecast is optimized with stochastic learning techniques that include input selection, model topology optimization, model output statistics, metric fitness optimization and machine learning. These forecasts are used by solar generators (plant managers), utilities and independent system operators for operations, scheduling, dispatching and market participation.

  11. Molecular mechanisms of xylose utilization by Pseudomonas fluorescens: overlapping genetic responses to xylose, xylulose, ribose and mannitol.

    Bacterial degradation of xylose is sequentially mediated by two enzymes - an isomerase (XutA) and a xylulokinase (XutB) - with xylulose as an intermediate. Pseudomonas fluorescens?SBW25, though capable of growth on xylose as a sole carbon source, encodes only one degradative enzyme XutA at the xylose utilization (xut) locus. Here, using site-directed mutagenesis and transcriptional assays, we have identified two functional xylulokinase-encoding genes (xutB1 and xutB2) and further show that expression of xutB1 is specifically induced by xylose. Surprisingly, xylose-induced xutB1 expression is mediated by the mannitol-responsive regulator MtlR, using xylulose rather than xylose as the direct inducer. In contrast, expression of the xutA operon is regulated by XutR - a transcriptional activator of the AraC family - in a xylose-, xylulose- and ribose-dependent manner. Detailed genetic and biochemical analyses of XutR, including DNase I footprinting assays, suggest an unconventional model of XutR regulation that does not involve DNA-looping, a mechanism typically found for AraC-type regulators from enteric bacteria. XutR functions as a dimer and recognizes two inverted repeat sequences, but binding to one half site is weak thus requiring an inducer molecule such as xylose for activation. PMID:26194109

    Full Text Available Polish language in the Republic of Belarus The situation of the Polish minority in Belarus was always difficult because the politics of Belarusian authorities was focused on destruction of anything connected with Polish culture or possessing Polish roots: intelligentsia, school, theatres, press. The reestablishing of Polish education in late 80-ties of the last century started from scratch therefore and the biggest amount of learners studied Polish in late 90-ties of the XX century. Recently the amount of students has decreased which is explained by the current demographical and political situation. The most significant influence on forming national consciousness is possesses by family. Unfortunately nowadays it is being observed that most of Polish families has not performed that function anymore and using of Polish language by members of Polish families is decreasing. The leading role of Polish language in a Catholic liturgy is changing as well: the word “Catholic” does not mean “Pole”. According to surveys 66% of Catholics would prefer Polish as the language of liturgy, 20% – Belarusian, 10% – Russian and Polish, 4% – another language. This situation creates the possibility of disappearing of Polish language from liturgy and catechism. Consequently the role of Polish schools and organizations in education of children and teenagers has increased. Language acquisition begins in kindergartens during extra lessons or within Polish groups. The forms of language acquisition at school vary a lot. Most of the students learn Polish languages after-hours, some of them attends required Polish classes at school. Moreover there are two Polish schools of Grodno region. There is an opportunity of studying Polish language in high educational establishments in Belarus, e.g. in Grodno State University Polish language department has existed since 1989 and it prepares its students to teaching Polish language. Farther development of Polish education in Belarus depends on both factors the Poles attitude and current political situation in the country. ???????? ???? ? ?????????? ????????????????? ????????? ????????????? ??????????? ? ?? ?????? ???? ???????, ??? ??? ???????? ??????? ???? ?????????? ?? ??????????? ?????, ??? ????? ???????? ????? ? ???? ??????? ? ???????? ?????????: ?????????????, ????, ???????, ?????. ? ????? ? ???? ??????????? ??????????? ?? ???????? ????? ? ????? 80-??? ????? ???????? ???????? ?????????? ? ???????? ?????? ? ?????????? ?????????? ???????? ??????? ???????? ???? ? ????? 90-??? ?????

    Full Text Available Observations on the Polish lexis in Lithuania on the borderland of Lithuania, Latvia and BelarusThe paper comments on the lexicon of Polish on the borderland of Lithuania, Latvia and Belarus (in the Zarasai district and the Ignalina district in Lithuania. The remarks, illustrated with selected examples, have been formulated on the basis of data gathered during field research in 2000–2001 and 2010–2011. The paper aims primarily at discussing the extent to which the collected material contributes to the state-of-the-art knowledge on the vocabulary of the North-Eastern Borderlands; the author analyzes the types of words present in the collected material in order to specify whether they are generally attested and well documented, or conversely – less known and only occasionally considered in literature.A large part of the collected material consists of vocabulary well known in Lithuania, and often in the whole area of the North-Eastern Borderlands. These include old expressions of various origin typical of the Eastern Borderlands, richly documented in works devoted to the Polish language of the North-Eastern Borderlands; loans from Lithuanian and Belorussian; or Polish archaic forms, e.g. asystentka ‘maid of honour’, budni ‘usual, ordinary’, fest ‘church fair’, gadzina ‘viper’, hurba ‘snowbank’, karszun ‘hawk’. Another numerous group are newer loanwords from Russian and Lithuanian, popularised in the post-war period, as well as in the recent years along with the changing role of the Lithuanian language, e.g. elektra ‘electric light, electri­city’, awto?awka ‘travelling shop’, balnica ‘hospital’.A small, yet extremely interesting for researchers, part of the lexis is composed of vocabulary not so well known in the North-Eastern Borderlands or in Lithuania, regionally bound (exhibited solely in the examined areas or in two former tightly-knit Polish-speaking areas, with limited frequency (rare words, appearing in various regions, yet seldom recognized, or restricted as far as the chronology is concerned (not attested presently, until now known only from older, pre-war sources, mainly from the works of Halina Turska, e.g. bracienik ‘cousin’, ciuszka ‘blowhole’, czelad? ‘children, offspring’, lun ‘marsh, swamp’, babaczka ‘bow tie’, murawiejnik ‘anthill’, cie?uszutka ‘heiferdim’, ?wiatle? ‘to shine’.A separate group encompasses words previously undocumented in literature, e.g. wieczuruszkowa? ‘to go to soirees, parties in the evening’, including the unknown word-formation variants, e.g. walaniantówka ‘epilepsy’ vs. walentaczka/walantaczka, or the regionally-bound diminutive forms with typical suffixes, today rare, e.g. buteleniatka ‘bottledim’, chustalutka ‘handkerchiefdim’.It is worth emphasizing that certain parts of the described vocabulary might still be commonly used, however the scarcity of extensive lexical research, as well as the lack of a full dictionary of Polish of the North-Eastern Borderlands render it impossible to resolve this question. ??????? ? ??????? ????????? ????? ? ????? ?? ????????-????????-??????????? ??????????? ?????? ???????? ??????? ? ??????? ????????? ?????, ???????????????? ? ????? ?? ????????-????????-??????????? ??????????

Results show that a possible way of understanding acupuncture, in an electrical way, should be to consider ionic flux redistribution between vascular and extra cell compartments. This is a two steps mechanism. The first one is starting with needles insertion and the second one is lasting with more intensity after removing them from skin.

The main part of the article deals with the ethnic and language changes which occurred in the last decade of the 20th and in the first decade of the 21st centuries. The statistical analysis and interpretation is based on data from three population censuses (1989, 1999, 2009. An ethnic structure and linguistic situation are presented with the emphasis placed on the status of the two languages commonly used in Belarus, i.e. Russian and Belarusian, as seen in two categories: of mother language and of the language used for communication at home. The conclusions prove the expansion of popularity of the Russian language and gradual decrease of the use of the Belarusian language, both in public and at home. The processes of Russification, which had begun in the Soviet period, are intensifying despite the fact that Belarus regained its political souverianity as a country. On the basis of quantitative data the author defines specific intensity and territorial distribution of the influence of the Russian language. The final part of the article shows political and geo-political consequences of these changes in Belarus.

The Polish language (including the language of the Polish press in Soviet Russia was subject to two powerful mechanisms: communist propaganda and totalitarianism. The language of the Polish press is characteristic of numerous divergences in relation to general Polish especially in vocabulary (the lexical level is dominated by the Russicisms and Sovietic elements. Comaparative analysis shows that the deviations from the general Polish occurred in both sources, but the specific inflexion features are not numerous. The flexion level is arisen under the influence of foreign language system (Belarussian and Russian.

    Full Text Available Fluorapophyllite crystals from complex veins crosscutting a small pectolite skarn bodyat the top of the Miêdzyrzecze sill were studied by means of chemical analysis, X-ray diffraction, thermalanalysis and both infrared and Raman spectroscopy. The apophyllite from Miêdzyrzecze, lacking abnormaloptical properties, is tetragonal with lattice parameters: a = 8.974(2 Å, c = 15.798(6 Å. DTA curves exhibittwo endothermic peaks centred at about 330 and 430C. The dehydration behaviour of apophyllite resultsfrom the development on the outer parts of grains of an amorphous layer. It forms a diffusion barrier thatmoderates H2O migration and originates in the second endothermic peak. IR investigations showed a newstretching vibration (OH, not previously recognized in apophyllite. This new band at 3627 cm–1 can beattributed to (OH of the hydroxyl group which substitutes for F– in the apophyllite structure. Selectiveleaching of phlogopite probably released the elements necessary for apophyllite precipitation in open spacesof the fissures in the upper part of the picrite sill.

  6. Single- and multi-frequency bioelectrical impedance analyses to analyse body composition in maintenance haemodialysis patients: comparison with dual-energy x-ray absorptiometry

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the adequacy of single-frequency (sf-BIA) and multi-frequency bioelectrical impedance analyses (mf-BIA), in comparison with dual-energy x-ray absorptiometry (DXA), to evaluate body composition in maintenance haemodialysis (MHD) patients. Body composition of 27 adult MHD patients (9 f, 18 m), BMI 17.5–34.4 kg m?2, was examined with DXA and BIA, with two different sf-BIA and 1 mf-BIA analysers. Biochemical markers of nutritional status and adequacy of dialytic treatment were also determined. Fat mass (FM) estimated by the different BIA analysers was found to be slightly but significantly higher than FM measured by DXA. In contrast, fat-free mass (FFM) obtained with BIA was found to be slightly but significantly lower than FFM DXA. No significant differences were found between LBM-DXA (that is FFM-DXA minus bone mass) and the different FFM BIA. The lowest mean prediction error versus DXA values was found with sf1BIA. In any case, a close correlation was found between all BIA values and DXA values, particularly for FFM. Furthermore, FFM and LBM results were significantly correlated with serum creatinine, which in MHD patients is an indicator of muscle mass. These results indicate that BIA can be used to evaluate body composition in MHD patients

  7. Validation of bioelectrical-impedance analysis as a measurement of change in body composition in obesity

    International Nuclear Information System (INIS)

    The bioelectrical-impedance-analysis (BIA) method accurately measures body composition in weight-stable subjects. This study validates the use of BIA to measure change in body composition. Twelve obese females underwent weight loss at a mean rate of 1.16 kg/wk. Body composition was measured by deuterium oxide dilution (D2O), BIA, and skinfold anthropometry (SFA) at baseline and at 5% decrements in weight. Highly significant correlations were obtained between D2O and BIA (r = 0.971) and between D2O and SFA (r = 0.932). Overall, BIA predicted change in fat-free mass with greater accuracy (to 0.4 kg) and precision (+/- 1.28 kg) than did anthropometry (to 0.8 kg and +/- 2.58 kg, respectively). We conclude that BIA is a useful clinical method for measuring change in body composition

    Bioimpedance analysis (BIA) is a well-known and tested method for body mass and muscular health assessment. Multi-frequency BIA (mfBIA) equipment now makes it possible to assess a particular muscle as a whole, as well as looking at a muscle at the fiber level. The aim of this study was to test the hypothesis that mfBIA can be used to assess the anatomical, physiological, and metabolic state of skeletal muscles. mfBIA measurements focusing on impedance, resistance, reactance, phase angle, center frequency, membrane capacitance, and both extracellular and intracellular resistance were carried out. Eight healthy human control subjects and three selected cases were examined to demonstrate the extent to which this method may be used clinically, and in relation to training in sport. The electrode setup is shown to affect the mfBIA parameters recorded. Our recommendation is the use of noble metal electrodes in connection with a conductance paste to accommodate the typical BIA frequencies, and to facilitate accurate impedance and resistance measurements. The use of mfBIA parameters, often in conjunction with each other, can be used to reveal indications of contralateral muscle loss, extracellular fluid differences, contracted state, and cell transport/metabolic activity, which relate to muscle performance. Our findings indicate that mfBIA provides a noninvasive, easily measurable and very precise momentary assessment of skeletal muscles.

  13. A Comprehensive Diagnostic Framework for Evaluating Business Intelligence and Analytics Effectiveness

    Directory of Open Access Journals (Sweden)

    Neil Foshay

    2015-09-01

    Full Text Available Business intelligence and analytics (BIA initiatives are costly, complex and experience high failure rates. Organizations require effective approaches to evaluate their BIA capabilities in order to develop strategies for their evolution. In this paper, we employ a design science paradigm to develop a comprehensive BIA effectiveness diagnostic (BIAED framework that can be easily operationalized. We propose that a useful BIAED framework must assess the correct factors, should be deployed in the proper process context and acquire the appropriate input from different constituencies within an organization. Drawing on the BIAED framework, we further develop an online diagnostic toolkit that includes a comprehensive survey instrument. We subsequently deploy the diagnostic mechanism within three large organizations in North America (involving over 1500 participants and use the results to inform BIA strategy formulation. Feedback from participating organizations indicates that BIA diagnostic toolkit provides insights that are essential inputs to strategy development. This work addresses a significant research gap in the area of BIA effectiveness assessment.

    2012-12-01

    High penetration renewable integration studies need high quality solar power data with spatial-temporal correlations that are representative of a real system. This paper will summarize the research relating sequential point-source sub-hour global horizontal irradiance (GHI) values to static, spatially distributed GHI values. This research led to the development of an algorithm for generating coherent sub-hour datasets that span distances ranging from 10 km to 4,000 km. The algorithm, in brief, generates synthetic GHI values at an interval of one-minute, for a specific location, using SUNY/Clean Power Research, satellite-derived, hourly irradiance values for the nearest grid cell to that location and grid cells within 40 km.

Níveis de GH, IGF-1 e GHBP foram determinados. Os produtos de PCR dos éxons 2-10 foram seqüenciados. RESULTADOS: O paciente apresentou níveis elevados de GH (26 µg/L), baixos de IGF-1 (22.5 ng/ml) e indetectáveis de GHBP. O seqüenciamento do éxon 5 do GHR revelou uma duplicação da adenina no nucleotídeo 338 da sequência de codificação do GHR (c.338dupA) em homozigose. CONCLUSÃO: Descrevemos uma nova mutação que causa um GHR truncado e uma perda da função do receptor devido à perda de aminoácidos compreendendo as regiões transmembrana e intracelular do receptor, levando a GHI. Abstract in english BACKGROUND: To date, about sixty different mutations within GH receptor (GHR) gene have been described in patients with GH insensitivity syndrome (GHI). In this report, we described a novel nonsense mutation of GHR. METHODS: The patient was evaluated at the age of 6 yr, for short stature associated [...] to clinical phenotype of GHI. GH, IGF-1, and GHBP levels were determined. The PCR products from exons 2-10 were sequenced. RESULTS: The patient had high GH (26 µg/L), low IGF-1 (22.5 ng/ml) and undetectable GHBP levels. The sequencing of GHR exon 5 disclosed adenine duplication at nucleotide 338 of GHR coding sequence (c.338dupA) in homozygous state. CONCLUSION: We described a novel mutation that causes a truncated GHR and a loss of receptor function due to the lack of amino acids comprising the transmembrane and intracellular regions of GHR protein, leading to GHI.

For instance, as additional solar power sites are added, the relative amount of variability should decrease due to spatial averaging of localized irradiance fluctuations. This presentation will summarize the research relating sequential point-source sub-hour global horizontal irradiance (GHI) values to static, spatially distributed GHI values. This research led to the development of an algorithm for generating coherent sub-hour datasets that span distances ranging from 10 km to 4,000 km. The algorithm, in brief, generates synthetic GHI values at an interval of one minute, for a specific location, using SUNY/Clean Power Research, satellite-derived, hourly irradiance values for the nearest grid cell to that location and grid cells within 40 km. During each hour, the observed GHI value for the grid cell of interest and the surrounding grid cells is related, via probability distributions, to one of live temporal cloud coverage classifications (class I, II, III, IV, V). Synthesis algorithms are used to select one-minute time step GHI values based on the classification of the grid cell of interest in a particular hour. Three primary statistical measures of the dataset are demonstrated: reduction in ramps as a function of aggregation; coherence of GHI values across sites ranging from 6 to 400 km apart over time scales from one minute to three hours; and ramp magnitude and duration distributions as a function of time of day and day of year.

  6. Multi-frequency bioimpedance in equine muscle assessment

    DEFF Research Database (Denmark)

    Harrison, Adrian Paul; ElbrØnd, Vibeke SØdring

    2015-01-01

    Multi-frequency BIA (mfBIA) equipment has been shown to be a non-invasive and reliable method to assess a muscle as a whole or at fibre level. In the equine world this may be the future method of assessment of training condition or of muscle injury. The aim of this study was to test if mfBIA reliably can be used to assess the condition of a horse's muscles in connection with health assessment, injury and both training and re-training. mfBIA measurements was carried out on 10 'hobby' horses and 5 selected cases with known anamnesis. Impedance, resistance, reactance, phase angle, centre frequency, membrane capacitance and both extracellular and intracellular resistance were measured. Platinum electrodes in connection with a conductance paste were used to accommodate the typical BIA frequencies and to facilitate accurate measurements. Use of mfBIA data to look into the effects of myofascial release treatment was also demonstrated. Our findings indicate that mfBIA provides a non-invasive, easily measurable and very precise assessment of the state of muscles in horses. This study also shows the potential of mfBIA as a diagnostic tool as well as a tool to monitor effects of treatment e.g. myofascial release therapy and metabolic diseases, respectively.

    This paper is devoted to the solution of the bi-fractional differential equation ({sup C}D{sup {alpha}}{sub t}u)(t, x) = {lambda}({sup L}D{sup {beta}}{sub x}u)(t, x) (t>0, -{infinity} 0 and {lambda} {ne} 0, with the initial conditions lim{sub x{yields}}{sub {+-}}{sub {infinity}} u(t,x) = 0 u(0+,x)=g(x). Here ({sup C}D{sup {alpha}}{sub t}u)(t, x) is the partial derivative coinciding with the Caputo fractional derivative for 0 < {alpha} < 1 and with the usual derivative for {alpha} = 1, while ({sup L}D{sup {beta}}{sub x}u)(t, x)) is the Liouville partial fractional derivative ({sup L}D{sup {beta}}{sub t}u)(t, x)) of order {beta} > 0. The Laplace and Fourier transforms are applied to solve the above problem in closed form. The fundamental solution of these problems is established and its moments are calculated. The special case {alpha} = 1/2 and {beta} = 1 is presented, and its application is given to obtain the Dirac-type decomposition for the ordinary diffusion equation.

    The present study was aimed at evaluating the feasibility and reliability of lower limb skeletal muscle (SM) mass estimates obtained by bioimpedance analysis (BIA). BIA estimates were compared with the estimates obtained by dual-energy X-ray absorptiometry (DXA). Ten normal weight and 10 obese women had BIA and DXA evaluations. Lower limb SM mass was then derived from DXA appendicular lean soft tissue estimates. Lower limb SM mass and SM distribution were also estimated from BIA modeling that fits measured resistance values along the leg. SM mass (mean +/- SD) was 5.8 +/- 1.0 kg by BIA vs. 5.8 +/- 1.1 kg by DXA in normal weight subjects and 7.2 +/- 1.4 kg by BIA vs. 7.2 +/- 1.2 kg by DXA in obese subjects. Mean +/- SD of the absolute value of the relative error was 7.0 +/- 3.4 and 5.9 +/- 3.4% in the two groups, respectively. Similar results were obtained by using five resistance values for the analysis. In conclusion, the proposed BIA model provides an adequate means of evaluating appendicular SM mass. PMID:12626475

  20. The value of bioelectrical impedance analysis and phase angle in the evaluation of malnutrition and quality of life in cancer patients-a comprehensive review.

    Grundmann, O; Yoon, S L; Williams, J J

    2015-12-01

    Bioelectrical impedance analysis (BIA) and especially its derived parameter phase angle have been widely used in different populations. The variability of BIA measures has often been cited as a major limitation for its clinical use in evaluating nutritional status and overall health of patients. Cancer patients often present with malnourishment and cachexia, which complicate the course of treatment and affect outcomes. PubMed, CINAHL, EBSCO and Cochrane Library have been searched for relevant publications in English for BIA in cancer patients. Out of 197 total results, 27 original research articles related to BIA measures in cancer patients were included in this review. Studies indicate that the use of BIA and phase angle measures can benefit in the clinical management of cancer patients in multiple ways: in the prevention; diagnosis; prognosis; and outcomes related to treatments that affect nutritional and overall health status. Phase angle and fat-free mass measures were most commonly evaluated and correlated with nutritional status and survival rate. One limitation of BIA measures is the high interpatient variability which requires careful interpretation of results in the context of the individual patient rather than comparison with population data. The BIA and phase angle provide practitioners for the evaluation of nutritional and overall health status in cancer patients with a convenient and non-invasive technique and should be encouraged.

  1. The use of bioelectrical impedance analysis for body composition in epidemiological studies

    DEFF Research Database (Denmark)

    Böhm, A; Heitmann, B L

    2013-01-01

    BACKGROUND/OBJECTIVES: Bioelectrical impedance analysis (BIA) is a relatively simple, inexpensive and non-invasive technique to measure body composition and is therefore suitable in field studies and larger surveys. SUBJECTS/METHODS: We performed an overview of BIA-derived body fat percentages (BF%) from 55 published studies of healthy populations aged 6-80 years. In addition, the relationship between body mass index (BMI) and body composition is documented in the context of BIA as a good alternative to closely differentiate which composition of the body better relates to the risk of cardiovascular diseases (CVDs)and all-cause mortality. RESULTS AND CONCLUSIONS: BIA-estimated percentage of BF varies greatly with population and age. BIA-estimated BF% is directly and closely related to various health outcomes such as CVDs, which is in contrast to BMI where both high and low BMIs are associated with increased risk of developing chronic diseases. Studies, among others using BIA, suggest that low BMI may reflectlow muscle and high BMI fat mass (FM). BIA-derived lean and FM is directly associated with morbidity and mortality. To the contrary, BMI is rather of limited use for measuring BF% in epidemiological studies.

    2004-01-01

    The use of bioelectrical impedance analysis (BIA) is widespread both in healthy subjects and patients, but suffers from a lack of standardized method and quality control procedures. BIA allows the determination of the fat-free mass (FFM) and total body water (TBW) in subjects without significant fluid and electrolyte abnormalities, when using appropriate population, age or pathology-specific BIA equations and established procedures. Published BIA equations validated against a reference method in a sufficiently large number of subjects are presented and ranked according to the standard error of the estimate. The determination of changes in body cell mass (BCM), extra cellular (ECW) and intra cellular water (ICW) requires further research using a valid model that guarantees that ECW changes do not corrupt the ICW. The use of segmental-BIA, multifrequency BIA, or bioelectrical spectroscopy in altered hydration states also requires further research. ESPEN guidelines for the clinical use of BIA measurements are described in a paper to appear soon in Clinical Nutrition.

  3. Initiatives to Reduce Earthquake Risk of Developing Countries

    Tucker, B. E.

    2008-12-01

    The seventeen-year-and-counting history of the Palo Alto-based nonprofit organization GeoHazards International (GHI) is the story of many initiatives within a larger initiative to increase the societal impact of geophysics and civil engineering. GHI's mission is to reduce death and suffering due to earthquakes and other natural hazards in the world's most vulnerable communities through preparedness, mitigation and advocacy. GHI works by raising awareness in these communities about their risk and about affordable methods to manage it, identifying and strengthening institutions in these communities to manage their risk, and advocating improvement in natural disaster management. Some of GHI's successful initiatives include: (1) creating an earthquake scenario for Quito, Ecuador that describes in lay terms the consequences for that city of a probable earthquake; (2) improving the curricula of Pakistani university courses about seismic retrofitting; (3) training employees of the Public Works Department of Delhi, India on assessing the seismic vulnerability of critical facilities such as a school, a hospital, a police headquarters, and city hall; (4) assessing the vulnerability of the Library of Tibetan Works and Archives in Dharamsala, India; (5) developing a seismic hazard reduction plan for a nonprofit organization in Kathmandu, Nepal that works to manage Nepal's seismic risk; and (6) assisting in the formulation of a resolution by the Council of the Organization for Economic Cooperation and Development (OECD) to promote school earthquake safety among OECD member countries. GHI's most important resource, in addition to its staff and Board of Trustees, is its members and volunteer advisors, who include some of the world's leading earth scientists, earthquake engineers, urban planners and architects, from the academic, public, private and nonprofit sectors. GHI is planning several exciting initiatives in the near future. One would oversee the design and construction of an earthquake- and tsunami-resistant structure in Sumatra to house a tsunami museum, a community training center, and offices of a local NGO that is preparing Padang for the next tsunami. This facility would be designed and built by a team of US and Indonesian academics, architects, engineers and students. Another initiative would launch a collaborative research program on school earthquake safety with the scientists and engineers from the US and the ten Islamic countries that comprise the Economic Cooperation Organization. Finally, GHI hopes to develop internet and satellite communication techniques that will allow earthquake risk managers in the US to interact with masons, government officials, engineers and architects in remote communities of vulnerable developing countries, closing the science and engineering divide.

  4. Modeling of global horizontal irradiance in the United Arab Emirates with artificial neural networks

    International Nuclear Information System (INIS)

    This paper employs ANN (Artificial Neural Network) models to estimate GHI (global horizontal irradiance) for three major cities in the UAE (United Arab Emirates), namely Abu Dhabi, Dubai and Al-Ain. City data are then used to develop a comprehensive global GHI model for other nearby locations in the UAE. The ANN models use MLP (Multi-Layer Perceptron) and RBF (Radial Basis Function) techniques with comprehensive training algorithms, architectures, and different combinations of inputs. The UAE models are tested and validated against individual city models and data available from the UAE Solar Atlas with good agreement as attested by the computed statistical error parameters. The optimal ANN model is MLP-based and requires four mean daily weather parameters; namely, maximum temperature, wind speed, sunshine hours, and relative humidity. The computed statistical error parameters for the optimal MLP-ANN model in relation to the measured three-cities mean data (referred to as UAE data) are MBE (mean bias error) = ?0.0003 kWh/m2, RMSE = 0.179 kWh/m2, R2 = 99%, NSE (Nash-Sutcliffe model Efficiency coefficient) = 99%, and t-statistic = 0.005 at 5% significance level. Results prove the suitability of the ANN models for estimating the monthly mean daily GHI in different locations of the UAE. - Highlights: • ANN prediction models for the GHI (global horizontal irradiance) in the UAE. • Models used to estimate the potential of global solar radiation for UAE cities. • Data from the UAE Solar Atlas are used to validate developed ANN models. • ANN models are more efficient than regression models in predicting GHI

CONCLUSÃO: BIA apresentou satisfatória sensibilidade e especificidade para predizer GV, entretanto, outros aparelhos e técnicas devem ser investigados para melhorar essa predição. Abstract in english OBJECTIVE: To evaluate the association between electrical bioimpedance analysis (BIA) and visceral fat (VF) in adult and elderly patients. SUBJECTS AND METHODS: This was a cross-sectional study, with a sample of 191 subjects (52% women, 49% elderly) stratified by sex, age and body mass. Computerized [...] tomography (VF area) and BIA (percentage of total body fat (%TBF-BIA), phase angle, reactance and resistance) data were generated. Statistical analysis was based on Pearson's Correlation Coefficient, Anova, Pearson's Chi-square, and ROC curves. RESULTS: VF areas > 130 cm² were more prevalent among the elderly and among men. Adult females showed a stronger correlation between GV and %TBF-BIA. The other groups showed similar results and statistically significant correlations. Correlations between GV and phase angle were weak and not statistically significant. ROC Curves analyzes showed the following %TBF-BIA, which identified excess VF: for male subjects: 21.5% (adults) and 24.25% (elderly); for female subjects: 35.05% (adults) and 38.45% (elderly) with sensitivity of 78.6%, 82.1%, 83.3%, and 66.7%, and specificity of 70.6%, 62.5%, 79.1%, and 69%, respectively. CONCLUSION: BIA was found to have satisfactory sensitivity and specificity to predict VF; however, other devices and other techniques should be investigated to improve VF prediction.

  5. Changes in body composition during weight loss in obese subjects in the NUGENOB study: Comparison of bioelectrical impedance vs. dual-energy X-ray absorptiometry

    DEFF Research Database (Denmark)

    Verdich, Camilla; Barbe, P

    2011-01-01

    AIM: We studied the accuracy of bioelectrical impedance analysis (BIA) to assess changes in body composition during moderate weight loss in obese subjects. METHODS: Estimates of changes in fat mass (FM) and fat-free mass (FFM) by BIA were compared with those by dual-energy X-ray absorptiometry (DXA) as the reference method during a 10-week standardized weight-loss intervention. In obese women (age: 20-50years, mean BMI: 33.8kg/m(2)) participating in a European multicentre trial (nutrient-gene interactions in human obesity [NUGENOB]), body composition was assessed by BIA (Bodystat QuadScan 4000) and DXA (Lunar DPX-IQ at two centres, Hologic QDR 2000 at another centre) at baseline (n=131) and at week 10 (n=105) after a mean weight loss of -5.7kg. RESULTS: At baseline, BIA significantly overestimated FFM and underestimated FM (by 1-3kg on average) compared with DXA, and the limits of agreement were wide (mean±7-8.5kg). For body-composition changes, although biases were generally non-significant, the limits of agreement were also wide (mean±3.7-4.6kg). An FFM prediction equation for BIA data was developed in subjects scanned with Lunar instruments and cross-validated in an independent sample of 31 obese women undergoing similar weight loss. However, no major improvement in limits of agreement was found. CONCLUSION: During moderate diet-induced weight loss, the use of BIA leads to estimates of changes in body composition at the individual level that can differ substantially from those assessed by DXA, indicating that BIA and DXA cannot be used interchangeably. However, BIA in this context may be used for assessing changes in body composition at group level.

    Current bioelectric impedance analysis (BIA) systems are often large, cumbersome devices which require strict electrode placement on the user, thus inhibiting mobile capabilities. In this work, we developed a handheld BIA device that measures impedance from multiple frequencies (5 kHz~200 kHz) with four contact electrodes and evaluated the BIA device against standard body composition analysis systems: a dual-energy X-ray absorptiometry (DXA) system (GE Lunar Prodigy, GE Healthcare, Buckinghamshire, UK) and a whole-body BIA system (InBody S10, InBody, Co. Ltd, Seoul, Korea). In the study, 568 healthy participants, varying widely in body mass index, age, and gender, were recruited at two research centers: the Samsung Medical Center (SMC) in South Korea and the Pennington Biomedical Research Center (PBRC) in the United States. From the measured impedance data, we analyzed individual body fat and skeletal muscle mass by applying linear regression analysis against target reference data. Results indicated strong correlations of impedance measurements between the prototype pathways and corresponding InBody S10 electrical pathways (R = 0.93, p body fat estimates from DXA did not yield significant differences (p > 0.728 (paired t-test), DXA mean body fat 29.45 ± 10.77 kg, estimated body fat 29.52 ± 12.53 kg). Thus, this portable BIA system shows a promising ability to estimate an individual's body composition that is comparable to large stationary BIA systems. PMID:26364636

    2004-01-01

    The urea volume of distribution (Vurea) is a key component of the Kt/V parameter calculated during urea kinetic modeling. The Vurea parameter has been approximated empirically using total body water (TBW) estimates derived from anthropometric formulas or measured by bioelectric impedance analysis (BIA). The author compared TBW values derived using various anthropometric formulas (Watson, Hume, Randall, Tzamaloukas, Chertow) and BIA to the Vurea parameter calculated using three point variable volume single pool urea kinetic modeling. A total of 127 chronic hemodialysis patients were studied (mean age 66 +/- 13 years; 42% female; 37% black; 47% diabetic). Agreement between anthropometric formulas, BIA, and Vurea values was assessed by linear regression and Bland Altman analyses. The closest correlations were obtained with the BIA (r = 0.972), Chertow (r = 0.917), and Tzamaloukas (r = 0.905) methods. When compared with Vurea, 95% confidence intervals by Bland Altman analysis were lowest with BIA (4L) and highest with the Watson method (8L). These results indicate that BIA best approximates Vurea in dialysis patients. PMID:15171475

  12. Bioelectrical impedance and visceral fat: a comparison with computed tomography in adults and elderly

    International Nuclear Information System (INIS)

    Objective: To evaluate the association between electrical bioimpedance analysis (BIA) and visceral fat (VF) in adult and elderly patients. Subjects and methods: This was a cross-sectional study, with a sample of 191 subjects (52% women, 49% elderly) stratified by sex, age and body mass. Computerized tomography (VF area) and BIA (percentage of total body fat (%TBF-BIA), phase angle, reactance and resistance) data were generated. Statistical analysis was based on Pearson's Correlation Coefficient, Anova, Pearson's Chi-square, and ROC curves. Results: VF areas ? 130 cm2 were more prevalent among the elderly and among men. Adult females showed a stronger correlation between GV and %TBF-BIA. The other groups showed similar results and statistically significant correlations. Correlations between GV and phase angle were weak and not statistically significant. ROC Curves analyzes showed the following %TBF-BIA, which identified excess VF: for male subjects: 21.5% (adults) and 24.25% (elderly); for female subjects: 35.05% (adults) and 38.45% (elderly) with sensitivity of 78.6%, 82.1%, 83.3%, and 66.7%, and specificity of 70.6%, 62.5%, 79.1%, and 69%, respectively. Conclusion: BIA was found to have satisfactory sensitivity and specificity to predict VF; however, other devices and other techniques should be investigated to improve VF prediction. (author)

    The use of portion control practices has rarely been quantified. The present study aimed to: (1) explore which portion control practices are actually used by the general population and their association with cognitive restraint, demographic background and general health interest (GHI), and (2) examine how the usage of portion control practices predicts the estimated consumption of an energy dense food (i.e. pizza). Twenty-two portion control practices were rated in terms of their frequency of use from ‘never’ to ‘very often’ by a representative sample of 1012 consumers from the island of Ireland. Three factors were extracted and named: measurement-strategy scale, eating-strategy scale, and purchasing-strategy scale. The eating-strategy scale score was the highest, while the measurement-strategy scale carried the lowest frequency score. For each strategy scale score, the strongest predictor was GHI, followed by gender. Having higher GHI and being female were independently associated with more frequent portion control. Both the eating-strategy scale score and the purchasing-strategy scale score were negatively associated with pizza portion size consumption estimates. In conclusion, while this study demonstrates that the reported use of portion control practices is low, the findings provide preliminary evidence for their validity. Further studies are needed to explore how portion control practices are used in different kinds of portion size decisions and what their contribution is to the intake of food over an extended period of time

    Full Text Available The traditional explanatory models used in epidemiology are “disease specific”, identifying risk factors for specific health conditions. Yet social exposures lead to a generalized, cumulative health impact which may not be specific to one illness. Disease-specific models may therefore misestimate social factors’ effects on health. Using data from the Canadian Community Health Survey and Canada 2001 Census we construct and compare “disease-specific” and “generalized health impact” (GHI models to gauge the negative health effects of one social exposure: socioeconomic position (SEP. We use logistic and multinomial multilevel modeling with neighbourhood-level material deprivation, individual-level education and household income to compare and contrast the two approaches. In disease-specific models, the social determinants under study were each associated with the health conditions of interest. However, larger effect sizes were apparent when outcomes were modeled as compound health problems (0, 1, 2, or 3+ conditions using the GHI approach. To more accurately estimate social exposures’ impacts on population health, researchers should consider a GHI framework.

  6. Surface Radiation from GOES: A Physical Approach; Preprint

    2012-09-01

    Models to compute Global Horizontal Irradiance (GHI) and Direct Normal Irradiance (DNI) have been in development over the last 3 decades. These models can be classified as empirical or physical, based on the approach. Empirical models relate ground based observations with satellite measurements and use these relations to compute surface radiation. Physical models consider the radiation received from the earth at the satellite and create retrievals to estimate surface radiation. While empirical methods have been traditionally used for computing surface radiation for the solar energy industry the advent of faster computing has made operational physical models viable. The Global Solar Insolation Project (GSIP) is an operational physical model from NOAA that computes GHI using the visible and infrared channel measurements from the GOES satellites. GSIP uses a two-stage scheme that first retrieves cloud properties and uses those properties in a radiative transfer model to calculate surface radiation. NREL, University of Wisconsin and NOAA have recently collaborated to adapt GSIP to create a 4 km GHI and DNI product every 30 minutes. This paper presents an outline of the methodology and a comprehensive validation using high quality ground based solar data from the National Oceanic and Atmospheric Administration (NOAA) Surface Radiation (SURFRAD) (http://www.srrb.noaa.gov/surfrad/sitepage.html) and Integrated Surface Insolation Study (ISIS) http://www.srrb.noaa.gov/isis/isissites.html), the Solar Radiation Research Laboratory (SRRL) at National Renewable Energy Laboratory (NREL), and Sun Spot One (SS1) stations.

    Most studies employing bioelectrical impedance analysis (BIA) for estimating appendicular skeletal muscle mass using descriptive BIA models rely on statistical rather than biophysical principles. The aim of the present study was to evaluate the feasibility of estimating arm and leg muscle volume (MV) based on multiple bioimpedance measurements and using a recently proposed mathematical model and to compare this technique to conventional segmental BIA at high and low frequencies. MV of the arm and leg, respectively, was determined in 15 young, healthy, active men [age 22 +/- 2 (SD) yr, total body fat 15.6 +/- 5.1%] by magnetic resonance imaging (MRI) and BIA using a conventional and new bioimpedance model. MRI-determined MV for leg and arm was 6,268 +/- 1,099 and 1,173 +/- 172 cm(3), respectively. Estimated MV by the new BIA model [leg: 6,294 +/- 1,155 cm(3) (50 kHz), 6,278 +/- 1,103 cm(3) (500 kHz); arm: 1,216 +/- 172 cm(3) (50 kHz), 1,155 +/- 157 cm(3) (500 kHz)] was not statistically different from MRI-determined MV (leg: P= 0.958; arm: P= 0.188). The new BIA model was superior to conventional BIA and performed best at 500 kHz for estimating leg MV as indicated by the lower relative total error [new: 3.6% (500 kHz), 5.2% (50 kHz); conventional: 7.6% (500 kHz) and 8.3% (50 kHz)]. In contrast, the new BIA model, both at 50 and 500 kHz, did not improve the accuracy for estimating arm MV [new: 10.8% (500 kHz), 10.6% (50 kHz); conventional: 11.8% (500 kHz), 11.4% (50 kHz)]. It was concluded that modeling of multiple BIA measurements has advantages for the determination of lower limb muscle volume in healthy, active adult men. PMID:17626831

  9. V-dotO2max prediction from multi-frequency bioelectrical impedance analysis

    International Nuclear Information System (INIS)

    Bioelectrical impedance analysis (BIA) has been shown to be highly related to skeletal muscle mass and blood volume, both of which are important determinants of maximal oxygen uptake (V-dotO2max). The aim of the present study was therefore to investigate the ability of whole-body and segmental multi-frequency BIA to improve current nonexercise V-dotO2max prediction models. Data for V-dotO2max (mL min?1), anthropometry, self-reported physical activity (PA-R) and BIA were collected in 115 men and women. Multiple linear regression analysis (MLR) was used to develop the most parsimonious prediction model. Segmental BIA was not superior to whole-body measurements. Correlation coefficients between V-dotO2max and resistance indices were significantly higher at 500 kHz compared to 50 kHz (p 2max (r = 0.89). After adjusting for age, gender and PA-R, MLR revealed that the inclusion of intracellular resistance index was slightly, but significantly (p 2max (?1). In short, whole-body BIA marginally improves the accuracy of nonexercise V-dotO2max prediction models and its advantage is most pronounced in individuals with particularly low V-dotO2max

    Full Text Available Analisar composição corporal é relevante para caracterizar necessidades nutricionais e fase de terminação de peixes. Objetivou-se estudar a relação entre variáveis ictiométricas (peso, comprimentos total e padrão, densidade e rendimentos), bromatológicas (gordura, proteína, cinza e umidade) e aquela [...] s da análise por bioimpedância ou BIA (resistência, reatância, ângulo de fase e índices de composição), no híbrido tambatinga (Colossoma macropomum x Piaractus brachypomus). Em um viveiro não fertilizado, 520 juvenis foram cultivados com ração comercial. Com idade de 136 dias após a eclosão dos ovos, 37,69 g de peso, 12,96 cm de comprimento total, 15 peixes, colhidos ao acaso, foram anestesiados (eugenol) e submetidos à primeira de quatorze avaliações quinzenais (BIA e biometria). Após eutanásia foram dissecados e pesados: carcaça inteira com cabeça, filé e pele (CICFP), filé com pele (FCP) e resto da carcaça com cabeça (CCC). Juntos, FCP e CCC foram moídos e homogeneizados para análise bromatológica. Estimativas da composição corporal e de rendimentos do tambatinga, com modelos incluindo variáveis ictiométricas e da BIA, apresentaram coeficientes de correlação entre 0,81 (para o rendimento do FCP) e 1,00 (para cinzas totais). Analogamente, modelos com a inclusão apenas de variáveis da BIA mostram coeficientes de correlação entre 0,81 (rendimento do FCP e do CCC) e 0,98 (para cinzas totais). Portanto, no tambatinga, a técnica da BIA possibilita a estimativa do rendimento de filé com pele e composição corporal (umidade, gordura, cinza e proteína). Os melhores modelos agregam variáveis ictiométricas e da BIA. Abstract in english Body composition analysis is relevant to characterize the nutritional requirements and finishing phase of fish. The aim of this study was to investigate the relationship between ichthyometric (weight, total and standard length, density and yields), bromatological (fat, protein, ash and water content [...] ) and bioelectrical-impedance-analysis (BIA) (resistance, reactance, phase angle and composition indexes) variables in the hybrid tambatinga (Colossoma macropomum × Piaractus brachypomus). In a non-fertilized vivarium, 520 juveniles were housed and fed commercial rations. Then, 136 days after hatching (DAH), 15 fish with an average weight of 37.69 g and average total length of 12.96 cm were randomly chosen, anesthetized (eugenol) and subjected to the first of fourteen fortnightly assessments (BIA and biometry). After euthanasia, the following parts were weighed: whole carcass with the head, fillet, and skin (WC); fillet with skin (FS); and the remainder of the carcass with the head (CH). Together, FS and CH were ground and homogenized for the bromatological analyses. Estimates of the body composition and yields of tambatinga, with models including ichthyometric and BIA variables, showed correlation coefficients ranging from 0.81 (for the FS yield) to 1,00 (for the total ash). Similarly, models that included only BIA variables had correlation coefficients ranging from 0.81 (FS and CH yields) to 0.98 (for the total ash). Therefore, in tambatinga, the BIA technique allows the estimation of the yield of the fillet with skin and the body composition (water content, fat, ash, and protein). The best models combine ichthyometric and BIA variables.

    tNon-lethal assessments of proximate body composition of fish can help unravelling the physiologicaland condition-dependent mechanisms of individual responses to ecological challenges. Common non-lethal methods designed to index nutrient composition in fish include the relative condition factor (Kn),bioelectric impedance-based assessments of body composition (BIA), and microwave-based “fat” meters(FM). Previous studies have revealed mixed findings as to the reliability of each of these. We compared theperformance of Kn, BIA and FM at different temperatures to predict energetic status of the whole bodiesof live eel (Anguilla anguilla) and carp (Cyprinus carpio) and the dorsal white muscle of carp. Homogenizedfish flesh was used for calibration. Relative dry mass was strongly correlated with relative fat content(R2up to 96.7%) and energy density (R2up to 99.1%). Thus, calibrations were only conducted for relativedry mass as an index of energetic status of a fish. FM readings were found to predict relative dry mass ofwhole body in eel (R2= 0.707) and carp (R2= 0.676), and dorsal white muscle of carp (R2= 0.814) well. Bycontrast, BIA measurements and Knwere much less suited to identify variation in relative dry mass. BIA-based models were also temperature-dependent. As a result, a regression model calibrated at 10?C andapplied to BIA measurements at 20?C was found to underestimate energetic status of a fish. By contrast,no effects of temperature on FM calibration results were found. Based on our study, the FM approach isthe most suitable method to non-lethally estimate energetic status in both, carp and eel, whereas BIA is oflimited use for energetic measurements in the same species, in contrast to other reports in the literature

    Microelectrophysiological and computer techniques were used in the study of background impulse activity (BIA) of the internal geniculate body (IGB) neurons and mesencephalic inferior tubers (MIT) of white rats. Definite differences were found in BIA by regularity, dynamic types and modality of interimpulse histograms. Mean frequency of MIT neuron discharges was 16-17 Hz and was about 3 times higher than in neurons of the IGB. Intraperitoneal injection of taurin noticeably suppressed neuronal activity in both nuclei. The drug reduced mean frequency of background impulse discharges both in MIT and IGB. Thus, taurin produces primarily suppressing modulating effect on neuronal activity of IGB and MIT. PMID:15496833

CONCLUSION: These findings show that both BIA-Segal and BIA-Gray equations are suitable for BF%, FM and FFM estimations in overweight and obese women.

    Full Text Available O presente estudo tem como objetivos: a verificar a concordância entre os métodos da impedância bioelétrica (BIA e da absortometria radiológica de dupla energia (DXA para a estimativa da massa muscular esquelética (MME; e b analisar o poder preditivo de variáveis antropométricas e da BIA para a predição da MME em idosas. Foram avaliadas 120 mulheres (60 a 81 anos, residentes na região Sul do Brasil. Mensuraram-se as variáveis antropométricas (massa corporal e estatura; a resistência e hidratação dos tecidos livres de gordura foram medidas pela técnica da BIA tetrapolar (Biodinamics - BF-310, e pela DXA de corpo inteiro (Lunar Prodigy DF + 14319 Radiation e software 7.52.002 DPX-L. A diferença entre os métodos foi verificada pelo teste t pareado, análise dos resíduos e o coeficiente de correlação. O valor preditivo das variáveis antropométricas e de BIA foi verificado pela regressão linear múltipla, adotando nível de significância de p 0,01. Observou-se que a BIA subestimou em média 0,8kg (IC95%: -3,7; 2,0kg a MME, quando comparada com a DXA. Foi observada alta correlação entre os métodos (r² = 0,75; p The objectives of the present study were: a to determine the agreement between bioelectrical impedance analysis (BIA and dual-energy X-ray absorptiometry (DXA for the estimation of skeletal muscle mass (SMM, and b to analyze the predictive power of anthropometric variables and BIA for the prediction of SMM in elderly women. A total of 120 women (60 to 81 years, living in the southern region of Brazil, were studied. Anthropometric variables (body weight and height were measured. Resistance and hydration of fat-free tissues were measured by tetrapolar BIA (Biodynamics, BF-310 and by whole-body DXA (Lunar Prodigy DF + 14319 Radiation and DPX-L software, version 7.52.002. Differences between methods were determined using the paired t-test, analysis of residuals and correlation coefficient. The predictive value of the anthropometric variables and BIA was evaluated by multiple linear regression, adopting a level of significance of p < 0.05. No significant difference in the estimation of SMM was observed between methods (p < 0.01. BIA underestimated SMM in mean of 0.8 kg (95%CI: -3.7; 2.0 kg when compared to DXA. Correlation between methods was high (r² = 0.75; p < 0.01. Regression analysis demonstrated that the ratio between the square of height and resistance (HEIGHT²/R explained 80% of the variation in SMM when adjusted to body weight and age, regardless of body fat, lean tissue hydration or body mass index. Thus, the BIA equation tested here is a valid tool for the estimation of SMM in elderly women and its value is best predicted by the regression model including HEIGHT²/R adjusted to body weight and age.

  18. Developing and testing solar irradiance forecasting techniques in the Hawaiian Islands region

    Matthews, D. K.; Souza, J. M.; Stein, K.

    2014-12-01

    Irradiance variability, primarily driven by cloud formation and advection, can be problematic in the state of Hawaíi, because of the high penetration of distributed solar and the small scale of the island electrical grids. The Hawaíi Natural Energy Institute (HNEI) is developing an operational system in order to research and test new techniques to generate solar forecasts for the Hawaiian Islands. The operational system comprises the following three components.(i) A ground-observation-based advection model, using sky imagers and a ceilometer located at the University of Hawaíi at M?noa. Every 10 minutes (during daylight hours), this component generates a high-resolution 1 hour Global Horizontal Irradiance (GHI) prediction for a region that is within ~15 km of the instrumentation. (ii) A satellite-image-based advection model, using Geostationary Operational Environmental Satellite (GOES) imagery and the Heliosat-II method. Every 30 minutes (during daylight hours), this component generates a 1 km resolution, 6 hour GHI prediction for the entire Hawaiian Archipelago. (iii) A coupled ocean-atmosphere model, using the Regional Ocean Modeling System (ROMS) model and the Weather Research and Forecasting (WRF) model, including newly available microphysics, shallow convection parameterization, and radiative transfer model options. Nightly, this component generates 48 hour GHI, Direct Normal Irradiance (DNI), and Diffuse Horizontal Irradiance (DHI) predictions for (a) a 10 km resolution domain covering the full Hawaiian Archipelago and (b) a nested 2 km resolution domain covering the islands of Maui, Óahu, and Hawaíi. We discuss the development and validation of the system, and the scales of forecasting accuracy for each component. We also examine the impact of the coupled model on the simulations of surface flux processeses and ocean-atmosphere feedbacks, both of which influence the prediction of regional cloud properties.

  19. Source apportionment of elevated wintertime PAHs by compound-specific radiocarbon analysis

    2008-12-01

    Full Text Available Natural abundance radiocarbon analysis facilitates distinct source apportionment between contemporary biomass/biofuel (14C "alive" versus fossil fuel (14C "dead" combustion. Here, the first compound-specific radiocarbon analysis (CSRA of atmospheric polycylic aromatic hydrocarbons (PAHs was demonstrated for a set of samples collected in Lycksele, Sweden a small town with frequent episodes of severe atmospheric pollution in the winter. Renewed interest in residential wood combustion means than this type of seasonal pollution is of increasing concern in many areas. Five individual/paired PAH isolates from three pooled fortnight-long filter collections were analyzed by CSRA: phenanthrene, fluoranthene, pyrene, benzo[b+k]fluoranthene and indeno[cd]pyrene plus benzo[ghi]perylene; phenanthrene was the only compound also analyzed in the gas phase. The measured ?14C for PAHs spanned from ?138.3‰ to 58.0‰. A simple isotopic mass balance model was applied to estimate the fraction biomass (fbiomass contribution that was constrained to a range of 71% for indeno[cd]pyrene+benzo[ghi]perylene to 87% for the gas phase phenanthrene and particulate fluoranthene, respectively. Indeno[cd]pyrene plus benzo[ghi]perylene, known to be enhanced in gasoline-powered motor vehicle exhaust compared to diesel exhaust, had the lowest contribution of biomass combustion of the measured PAHs by 9%. The total organic carbon (TOC, defined as carbon remaining after removal of inorganic carbon fbiomass was estimated to be 77%, which falls within the range for PAHs. This CSRA data of atmospheric PAHs demonstrate the non-uniformity of biomass combustion contribution to different PAHs even in a location with limited local emission sources and illustrates that regulatory efforts would not evenly reduce all PAHs.

  20. Artificial neural network based daily local forecasting for global solar radiation

    International Nuclear Information System (INIS)

    Highlights: • A new method for local forecasting of daily global solar radiation is proposed. • The model combines the artificial neural networks and the special modelling. • The model exploits weather forecasts provided by specialized agency. • The model’s forecasts were compared to measured data for two locations. • The developed model estimates daily solar radiation with satisfactory accuracy. - Abstract: When a part of the power is generated by grid connected photovoltaic installations, an effective global solar irradiation (GSI) forecasting tool becomes a must to ensure the quality and the security of the electrical grid. GSI forecasts allow the quantification of generated photovoltaic (PV) power and helps electrical grid operators anticipate problems related to the nature of PV power and the planning for adequate solutions and decisions. In this study, a new methodology for local forecasting of daily global horizontal irradiance (GHI) is proposed. This methodology is a combination of spatial modelling and artificial neural networks (ANNs) techniques. An ANN based model is developed to predict the local GHI based on daily weather forecasts provided by the US National Oceanic and Atmospheric Administration (NOAA) for four neighbouring locations. The methodology was tested for two locations; Le Bourget du Lac (45°38?44?N, 5°51?33?E), which is located in the French Alps and Cadarache (43°42?28?N, 05°46?31?E), which is located in the south of France. The model’s forecasts were compared to measured data for the two locations and validation results indicate that the ANN-based method presented in this study can estimate daily GHI with satisfactory accuracy

  1. Analysis and Prediction of Energy Production in Concentrating Photovoltaic (CPV Installations

    Directory of Open Access Journals (Sweden)

    Allen Barnett

    2012-03-01

    Full Text Available A method for the prediction of Energy Production (EP in Concentrating Photovoltaic (CPV installations is examined in this study. It presents a new method that predicts EP by using Global Horizontal Irradiation (GHI and the Photovoltaic Geographical Information System (PVGIS database, instead of Direct Normal Irradiation (DNI data, which are rarely recorded at most locations. EP at four Spanish CPV installations is analyzed: two are based on silicon solar cells and the other two on multi-junction III-V solar cells. The real EP is compared with the predicted EP. Two methods for EP prediction are presented. In the first preliminary method, a monthly Performance Ratio (PR is used as an arbitrary constant value (75% and an estimation of the DNI. The DNI estimation is obtained from GHI measurements and the PVGIS database. In the second method, a lineal model is proposed for the first time in this paper to obtain the predicted EP from the estimated DNI. This lineal model is the regression line that correlates the real monthly EP and the estimated DNI in 2009. This new method implies that the monthly PR is variable. Using the new method, the difference between the predicted and the real EP values is less than 2% for the annual EP and is in the range of 5.6%–16.1% for the monthly EP. The method that uses the variable monthly PR allows the prediction of the EP with reasonable accuracy. It is therefore possible to predict the CPV EP for any location, using only widely available GHI data and the PVGIS database.

    2012-08-01

    Full Text Available Benzylisoquinoline alkaloid biosynthesis. The benzylisoquinoline alkaloids (BIA are specialized metabolites with an ancient phylogeneticdistribution, but still preserved in modern clades. Some of them, such as morphine, sanguinerine or berberine, are important for modernmedicine. This review discusses the highlights of the current state of the biosynthesis of BIA. There have been studies that show thebiosynthesis of 22 of these nitrogenous metabolites. In their formation there are 43 enzymes grouped into oxidoreductases, transferasesand lyases, which in some cases represent atypical examples of the manner in which the secondary metabolism diversification wasoriginated. Two of these examples are the cytochrome proteins P450 (P450, with catalytic activities for ABI route, or the norcoclaurinesynthase enzyme (NCS, which share substantial identity with defense allergenic proteins. Likewise, there are genetic advances thathave produced the characterization of 30 enzymes, allowing knowledge of regulatory processes. Another interesting aspect is thecompartmentation of the biosynthesis sites and accumulation of BIA, since in several cases they are spatially separated and in differentspecies, or in the same species several types of cells may be involved. This has suggested intra and intercellular transport of alkaloids,precursors and enzymes, and it has been documented berberine transport between the cytoplasm and the vacuoles of storage. The picturefor the biosynthesis of BIA has been constructed with exemplary studies of alkaloids with pharmacological importance.

  18. Parental Involvement in Brief Interventions for Adolescent Marijuana Use

    Science.gov (United States)

    Piehler, Timothy F.; Winters, Ken C.

    2015-01-01

    Adolescents (aged 12–18 years) identified in a school setting as abusing marijuana and other drugs were randomly assigned to complete one of two brief interventions (BIs). Adolescents and their parent (N = 259) were randomly assigned to receive either a 2-session adolescent only (BI-A) or a 2-session adolescent and additional parent session (BI-AP). Interventions were manualized and delivered in a school setting by trained counselors. Adolescents were assessed at intake and at 6 months following the completion of the intervention. Using a latent construct representing 6-month marijuana use outcomes, current findings supported previous research that BI-AP resulted in superior outcomes when compared to BI-A. The presence of a marijuana dependence diagnosis at baseline predicted poorer outcomes when compared to youth without a diagnosis. Both baseline diagnostic status and co-occurring conduct problems interacted with intervention condition in predicting marijuana use outcomes. A marijuana dependence diagnosis resulted in a greater negative impact on marijuana use outcomes within the BI-A condition when compared to BI-AP. Co-occurring conduct problems had a greater negative impact on marijuana use outcomes within the BI-AP intervention when compared to BI-A. Implications for implementing BIs given diagnostic status, parent involvement and co-occurring conduct problems are discussed. PMID:26415058

    Full Text Available Hematopoietic stem cell transplantation (HSCT is widely used in the treatment of malignant and autoimmune diseases. Various complications often develop during the post-transplantation period that can significantly impair the clinical outcomes, so the ability to predict therisk of severe complications is of great practical importance. Predictive value of some anthropometric indices and bioimpedance analysis(BIA measured before conditioning to assess the risks of serious complications and graft hypofunction in the early post-transplant period(100 days were analyzed. Anthropometry and BIA used in a comprehensive assessment of nutritional status in order to optimize the nutritional support of these patients. 101 patients were examined before conditioning and at different times during the early post-transplant period: 50 children (5–17 years of age were examined using BIA and anthropometry, 61 children (6 months – 4 years of age – using only anthropometry without BIA due to age restrictions. The prognostic value of the phase angle (FA, ratio of the active cell mass to lean body mass (ACM/LBM and shoulder muscle circumference (SMC was shown. Thus, in patients with FA ? 4, ACM/LBM < 0.45 and SMC ? 10th percentile before conditioning risk of severe complications during early post-transplant period was significantly higher (p < 0.05. Also, in patients with FA ? 4 and ACM/LBM < 0.45 a significantly higher risk of graft hypofunction developing was observed (p < 0.05.

  10. Can abdominal bioelectrical impedance refine the determination of visceral fat from waist circumference?

    International Nuclear Information System (INIS)

    Ryo et al (2005 Diabetes Care 28 451–3) reported a new method for measuring the visceral fat area (VFA) by combining abdominal bioelectrical impedance analysis (BIA) with measurement of waist circumference (WC), but very few methodological details were provided. Furthermore, the study did not test the use of WC alone as an indicator of VFA even though others had previously reported a strong correlation. We sought to determine the optimal measurement technique and analysis for measuring VFA by abdominal BIA and WC. 18 volunteers (age 23–64 years) underwent measurement of WC, abdominal impedance (Bodystat 500 four-electrode system) and a single cross-sectional CT scan at the umbilicus. VFA derived using WC3 and measurements of abdominal impedance from electrode pairs sited at the flank predicted the value of VFA measured by CT with correlation r = 0.904 (p 1.9 alone, without involving BIA at all, provided a similar correlation (r = 0.923). Our small preliminary study shows that abdominal BIA is potentially a practicable non-invasive technique for measurement of VFA but casts doubt on whether it adds any value to the use of WC alone. Larger studies are now required to test this finding. (note)

    Solar radiation is the driving force for the earth's weather and climate. Understanding the elements of this dynamic energy balance requires accurate measurements of broadband solar irradiance. Since the mid-1990's the ARM Program has deployed pyrheliometers and pyranometers for the measurement of direct normal irradiance (DNI), global horizontal irradiance (GHI), diffuse horizontal irradiance (DHI), and upwelling shortwave (US) radiation at permanent and mobile field research sites. This poster summarizes the basis for assessing the broadband solar radiation data available from the SIRS, SKYRAD, and GNDRAD measurement systems and provides examples of data inspections.

    Full Text Available Abstract Background Bioimpedance analysis (BIA has been reported as helpful in identifying hypervolemia. Observation data showed that hypervolemic maintenance hemodialysis (MHD patients identified using BIA methods have higher mortality risk. However, it is not known if BIA-guided fluid management can improve MHD patients’ survival. The objectives of the BOCOMO study are to evaluate the outcome of BIA guided fluid management compared with standard care. Methods This is a multicenter, prospective, randomized, controlled trial. More than 1300 participants from 16 clinical sites will be included in the study. The enrolment period will last 6 months, and minimum length of follow-up will be 36 months. MHD patients aged between 18 years and 80 years who have been on MHD for at least 3 months and meet eligibility criteria will be invited to participate in the study. Participants will be randomized to BIA arm or control arm in a 1:1 ratio. A portable whole body bioimpedance spectroscopy device (BCM—Fresenius Medical Care D GmbH will be used for BIA measurement at baseline for both arms of the study. In the BIA arm, additional BCM measurements will be performed every 2 months. The primary intent-to-treat analysis will compare outcomes for a composite endpoint of death, acute myocardial infarction, stroke or incident peripheral arterial occlusive disease between groups. Secondary endpoints will include left ventricular wall thickness, blood pressure, medications, and incidence and length of hospitalization. Discussions Previous results regarding the benefit of strict fluid control are conflicting due to small sample sizes and unstable dry weight estimating methods. To our knowledge this is the first large-scale, multicentre, prospective, randomized controlled trial to assess whether BIS-guided volume management improves outcomes of MHD patients. The endpoints of the BOCOMO study are of utmost importance to health care providers. In order to obtain that aim, the study was designed with very careful important considerations related to the endpoints, sample size, inclusion criteria, exclusion criteria and so on. For example, annual mortality of Beijing MHD patients was around 10%. To reach statistical significance, the sample size will be very large. By using composite endpoint, the sample size becomes reasonable and feasible. Limiting inclusion to patients with urine volume less than 800 ml/day the day before dialysis session will limit confounding due to residual renal function effects on the measured parameters. Patients who had received BIS measurement within 3 months prior to enrolment are excluded as data from such measurements might lead to protocol violation. Although not all patients enrolled will be incident patients, we will record the vintage of dialysis in the multivariable analysis. Trial registration Current Controlled Trials NCT01509937

    Full Text Available Hay diversos métodos disponibles para medir el consumo de energía en el ser humano. Debido al alto costo y pequeño número de laboratorios capaces de utilizar la calorimetría directa y la técnica del agua doblemente marcada, se ha realizado un número relativamente pequeño de mediciones del gasto energético utilizándose estos métodos. Así, cada día más, los investigadores se atienen en alto grado a los métodos de calorimetría indirecta (CI y bioimpedancia eléctrica (BIA y los clínicos a las ecuaciones de predicción para calcular los requerimientos de energía total en sus estudios y pacientes respectivamente. Objetivo: Evaluar el Gasto Energético Basal (GEB y el Gasto Energético Total (GET de individuos saludables comparando los resultados de CI, BIA y ecuaciones predictivas con los de requerimiento estimado de energía (EER, Fleisch, FAO/WHO/UNU 1985 y 2001.

Due to the high cost and small number of laboratories able to perform it, the direct calorimetry and doubly labeled water technique are rarely used to measure the energy expenditure. As consequence, there is an increase use of the indirect calorimetry and bioelectrical impedance analysis methods by researchers and predictive equations by physicians to calculate the total energy requirements in research and in clinic. Objective: To evaluate the basal energy expenditure (GEB and total energy expenditure (GET of healthy subjects comparing results of indirect calorimetry (CI, bioelectrical impedance analysis (BIA and predictive equations such as estimated energy requirements (EER, Fleish, FAO/WHO/UNU 1985 and 2001.

Of these, the GEB by predictive equations FAO/WHO/UNU 1985 and 2001 and the GET by EER, Fleisch and FAO/WHO/UNU 1985 and 2001 were calculated. The data was analyzed with the software Sigma Stat for Windows version 2.03 and Dunn's test was used for comparison of mean obtained with methods and equations (p < 0.05. Results: It was verified that 60.5% of the participants were men. The majority of subjects were eutrofic. BIA showed significant differences between men and women. The differences between the values of GEB, obtained by BIA and CI, were statistically significant only for women (p < 0.05 with an underestimation of the GEB results obtained by BIA in relation to those obtained by CI. Significant difference was found between the predictive equations and CI for both sexes, also demonstrating an underestimation of the equations in relation to CI. It was observed an overestimation of GET with the predictive equations of FAO/WHO/UNU/85 and 2001 in relation to EER and Fleisch for both sexes. Conclusion: The estimation of GEB can be carried out by both BIA and CI, although BIA must be used with criteria since it underestimates in a significant way for women. In relation to the predictive equations, overestimation can develop positive energy balance in populations with risks for overweight and obesity. Thus, it is necessary comparisons to identify the limitations of each method.

    In the fall of 2010, a multiyear pilot energy efficiency retrofit project was undertaken by Greenbelt Homes, Inc., (GHI) a 1,566 home cooperative of circa 1930 and 1940 homes in Greenbelt, Maryland. GHI established this pilot project to serve as a basis for decision making for the rollout of a community-wide upgrade program that will incorporate energy efficiency improvements to the building envelope and mechanical equipment. With the community upgrade fully funded by the cooperative through their membership without outside subsidies, this project presents a unique opportunity to evaluate and prioritize the wide range of benefits of high-performance retrofits based on member experience with and acceptance of the retrofit measures implemented during the pilot project. Addressing the complex interactions between benefits, trade-offs, construction methods, project management implications, realistic upfront costs, financing, and other considerations, serves as a case study for energy retrofit projects that include high-performance technologies based on the long-term value to the homeowner. The pilot project focused on identifying the added costs and energy-savings benefits of improvements. Phase 1—baseline evaluation for a representative set of 28 homes sited in seven buildings; Phase 2—installation of the building envelope improvements and continued monitoring of the energy consumption for the heating season; Phase 3—energy simulations supporting recommendations for HVAC and water heating upgrades.

    The purification and biochemical characterization of the respiratory membrane-bound nitrate reductase from Sinorhizobium meliloti 2011 (Sm NR) is reported together with the optimal conditions for cell growth and enzyme production. The best biomass yield was obtained under aerobic conditions in a fed-batch system using Luria-Bertani medium with glucose as carbon source. The highest level of Sm NR production was achieved using microaerobic conditions with the medium supplemented with both nitrate and nitrite. Sm NR is a mononuclear Mo-protein belonging to the DMSO reductase family isolated as a heterodimeric enzyme containing two subunits of 118 and 45 kDa. Protein characterization by mass spectrometry showed homology with respiratory nitrate reductases. UV-Vis spectra of as-isolated and dithionite reduced Sm NR showed characteristic absorption bands of iron-sulfur and heme centers. Kinetic studies indicate that Sm NR follows a Michaelis-Menten mechanism (K (m) = 97 ± 11 ?M, V = 9.4 ± 0.5 ?M min(-1), and k (cat) = 12.1 ± 0.6 s(-1)) and is inhibited by azide, chlorate, and cyanide with mixed inhibition patterns. Physiological and kinetic studies indicate that molybdenum is essential for NR activity and that replacement of this metal for tungsten inhibits the enzyme. Although no narGHI gene cluster has been annotated in the genome of rhizobia, the biochemical characterization indicates that Sm NR is a Mo-containing NR enzyme with molecular organization similar to NarGHI.

    The occurrence of polycyclic aromatic hydrocarbons (PAHs) in smoked fish as a consequence of cold smoking was studied. Raw fillets of Salmo salar from Norway or the Irish Sea were sampled in a modern smokehouse and examined for PAH content. The same fillets, labeled with an identification number, were sampled immediately after the smoking process and analyzed. Among the investigated compounds, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, benz[a]anthracene, chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, and benzo[ghi]perylene were detected in both raw and smoked fillets. No significant difference (P smoked samples in the concentrations of six PAHs, but significant differences were found for fluorene, anthracene, fluoranthene, benz[a]anthracene, and benzo[ghi]perylene. Results confirm that PAHs concentrations in smoked fish are the product of both sea pollution and the smoking process. A modern smoking plant with an external smoke generator and a mild treatment as described here will not add significantly to the concentration of PAHs, except for some compounds. PMID:16715815

  7. Pre- and syn-Ross orogenic granitoids at Drake Head and Kartografov Island, Oates Coast, northern Victoria Land, East Antarctica

    International Nuclear Information System (INIS)

    The majority of the Oates Coast, northern Victoria Land granitoids, typified by those at Drake Head and Kartografov Island (Harald Bay), are monzogranites with lesser granodiorites and minor quartz-monzodiorite and syenogranite. All are plagioclase-K-feldspar-biotite granitoids with additional muscovite, garnet and/or hornblende, and are subalkaline and peraluminous. Berg Granite typifies the early Ordovician, Granite Harbour Instrusive (GHI) suite of the Ross Orogen at the Oates Coast. Granitoids from Kartografov Island have higher amounts of Fe+Mg+Ti and an ambiguous Rb-Sr geochronology: they could be either pre-Ross Orogeny in age, or syn-Ross Orogeny and representing a lower structural level of GHI. The Drake Head granite gneiss has a fractionated leuco-granite composition similar to Berg Granite, and is intruded by granite and granodiorite. Rb-Sr ages indicate that all are Neoproterozoic, although the granite gneiss result is probably an errorchron age, reflecting its less uniform nature (granodiorite:649 ± 30 Ma, initial ratio 0.7065 +/- 6; granite gneiss: 682 ± 140 Ma, initial ratio 0.7107 ± 50). These late Neoproterozoic granitoids provide a source for distinctive detrital zircon age components in extensive early Paleozoic turbidites of Australia-New Zealand-Antarctica.

    Clear sky models estimate the terrestrial solar radiation under a cloudless sky as a function of the solar elevation angle, site altitude, aerosol concentration, water vapor, and various atmospheric conditions. This report provides an overview of a number of global horizontal irradiance (GHI) clear sky models from very simple to complex. Validation of clear-sky models requires comparison of model results to measured irradiance during clear-sky periods. To facilitate validation, we present a new algorithm for automatically identifying clear-sky periods in a time series of GHI measurements. We evaluate the performance of selected clear-sky models using measured data from 30 different sites, totaling about 300 site-years of data. We analyze the variation of these errors across time and location. In terms of error averaged over all locations and times, we found that complex models that correctly account for all the atmospheric parameters are slightly more accurate than other models, but, primarily at low elevations, comparable accuracy can be obtained from some simpler models. However, simpler models often exhibit errors that vary with time of day and season, whereas the errors for complex models vary less over time.

    Many low- and middle-income countries are seeking to reform their health financing systems to move towards universal coverage. This typically means that financing is based on people's ability to pay while, for service use, benefits are based on the need for health care. Financing incidence analysis (FIA) and benefit incidence analysis (BIA) are two popular tools used to assess equity in health systems financing and service use. FIA studies examine who pays for the health sector and how these contributions are distributed according to socioeconomic status (SES). BIA determines who benefits from health care spending, with recipients ranked by their relative SES. In this article, we identify 10 resources to assist researchers and policy makers seeking to undertake or interpret findings from financing and benefit incidence analyses in the health sector. The article pays particular attention to the data requirements, computations, methodological challenges and country level experiences with these types of analyses. PMID:25255919

    One hundred and twenty undergraduate women students reported their height and weight and completed the Eating Disorder Questionnaire (EDQ), the Eysenck Personality Inventory (EPI), the Beck Depression Inventory (BDI), the Family Assessment Device (FAD), the Body Shape Questionnaire (BSQ), the Body Image Assessment (BIA), and measures of peer and media influence. Family functioning was shown to be a poor predictor of bulimic behavior, whereas peer influence was a significant predictor. Media influence interacted with body dysphoria to increase the likelihood of bulimic behavior. The BSQ was a better predictor of bulimic behavior than the BIA, suggesting that students' responses to a measure that asks questions about specific areas of the body may reflect their feelings of body dysphoria more accurately than a measure that relies on a generalized silhouette.

    Full Text Available A fast, simple procedure for simultaneous determination of sulfamethoxazole (SMX and trimethoprim (TMP was performed using batch injection analysis with multiple pulse amperometric detection (BIA-MPA. The sample aliquot (150 µL was directly injected onto the boron-doped diamond (BDD electrode (wall-jet configuration immersed in a BIA system. The analytical characteristics of the proposed method include high analytical frequency (up to 75 injections per hour, good stability (RSD < 2.9%; n = 10, low detection limits (0.227 and 0.173 mg L-1 for SMX and TMP, respectively and minimal waste generation. The proposed method yielded similar results to those obtained by liquid chromatography at a 95% confidence level.

    Full Text Available Antecedentes y objetivos: La obesidad infantil está aumentando alarmantemente en las últimas décadas. Para evaluar la utilidad del índice de masa corporal (IMC), el grosor del pliegue cutáneo (GPC), la circunferencia de la cintura (CC), y la impedancia bioeléctrica pie-a-pie (BIA-PP) para el cribado [...] de la obesidad en poblaciones con diversidad de razas utilizando una técnica de impedancia bioeléctrica tetrapolar (BIA-T) como el método de referencia. Métodos y resultados: se realizó un estudio transversal poblacional in la ciudad de Ouro Preto, Brasil, en el 2006. Se distribuyó al azar a escolares de 6-15 años (n = 788), que se seleccionaron en función de la edad y el sexo, estratificados por la proporción de estudiantes en cada colegio de la ciudad. Se utilizó un análisis no paramétrico de curvas ROC para definir la sensibilidad y la especificidad para cada método estudiado empleando el método tetrapolar como referencia. El IMC y la BIA-PP fueron los más idóneos para el cribado de la obesidad en las etapas prepuberales y puberales puesto que presentan un equilibrio mejor entre la sensibilidad y la especificidad y un menor fallo de clasificación. Para los niños prepúberes, el BF-GPC-D fue el mejor método de evaluación de la grasa corporal. Conclusión: Los resultados sugieren que la BIA-PP y el IMC son los métodos de elección para el cribado de la obesidad en poblaciones mixtas y que el método de elección para el cribado de la grasa corporal debe realizarse de acuerdo con la madurez sexual de los chicos y chicas. Este estudio demuestra la necesidad de realizar estudios en poblaciones mixtas más amplias para determinar los parámetros antropológicos y examinar la capacidad predictiva de los métodos y los puntos de corte obtenidos aquí en el desarrollo de la obesidad. Abstract in english Background and aims: Childhood obesity is increasing dramatically in last decades. To evaluate the usefulness of body mass index (BMI), skinfold thickness (ST), waist circumference (WC), and foot-to-foot bioelectrical impedance (BIA-FF) for screening for obesity in mixed-race popu lation, using the [...] tetrapolar bioelectrical impedance (BIA-T) technique as reference method. Methods and results: A cross-sectional-based population study was performed in the city of Ouro Preto, Brazil, in 2006. Schoolchildren aged 6-15 years (n = 788) was randomly selected according to age and sex stratified by the proportion of students in each schools of the city. Nonparametric receiver operating characteristic (ROC) analysis was used to define the sensitivity and specificity for each method studied using the tetrapolar method as reference. The BMI and the BIA-FF were the most suitable for adiposity screening in pre-pubertal and pubertal stages because they present a better balance between sensitivity and specificity, and smaller misclassification. For post-pubertal boys, the BF-ST-D was the best body fat assessment method. Conclusion: The results suggest that BIA-FF and BMI are choice methods for obesity screening in mixed population and that the method choice for body fat screening must be done according to sexual maturity of boys and girls. The present study demonstrates the need to perform studies in wider mixed-race population to determine anthropometric parameters and to examine the predictive ability of methods and cut-offs here elucidated in the development of obesity.

    Nonalcoholic fatty liver disease (NAFLD) is the commonest chronic liver disease and includes simple steatosis and nonalcoholic steatohepatitis (NASH). Since NASH progresses to cirrhosis more frequently and increases liver-related and cardiovascular disease risk substantially more than simple steatosis, there is a great need to differentiate the two entities. Liver biopsy is the gold standard for the diagnosis of NAFLD but its disadvantages, including the risk of complications and sampling bia...

    Vocal tract length normalisation (VTLN) is a well known rapid adaptation technique. VTLN as a linear transformation in the cepstral domain results in the scaling and translation factors. The warping factor represents the spectral scaling parameter. While, the translation factor represented by bias term captures more speaker characteristics especially in a rapid adaptation framework without having the risk of over-fitting. This paper presents a complete and comprehensible derivation of the bia...

  11. Effect of skin temperature on multifrequency bioelectrical impedance analysis.

    1996-08-01

    This study assessed the effects of changes in skin temperature on multifrequency bioimpedance analysis (MF-BIA) and on the prediction of body water compartments. Skin temperature (baseline 29.3 +/- 2.1 degrees C) of six healthy adults was raised over 50 min to 35.8 +/- 0.6 degrees C, followed by cooling for 20 min to 26.9 +/- 1.3 degrees C, by using an external heating and cooling blanket. MF-BIA was measured at both distal (conventional) and proximal electrode placements. Both distal and proximal impedance varied inversely with a change in skin temperature across all frequencies (5-500 kHz). The change in proximal impedance per degree centigrade change in skin surface temperature was approximately 60% of distal impedance. The change in measured impedance at 50 kHz erroneously increased predicted total body water (TBW) by 2.6 +/- 0.9 liters (P modeling of the MF-BIA data indicated changes in predicted water compartments with temperature modifications; however, the ratio of extracellular water (ECW) to TBW did not significantly change (P < 0.4). This change in impedance was not due to a change in the movement of water of the ECW compartment and thus probably represents a change in cutaneous impedance of the skin. Controlled ambient and skin temperatures should be included in the standardization of BIA measurements. The error in predicted TBW is < 1% within an ambient temperature range of 22.3 to 27.7 degrees C (72.1-81.9 degrees F). PMID:8872654

    Full Text Available Abstract Background Few equations have been developed in veterinary medicine compared to human medicine to predict body composition. The present study was done to evaluate the influence of weight loss on biometry (BIO, bioimpedance analysis (BIA and ultrasonography (US in cats, proposing equations to estimate fat (FM and lean (LM body mass, as compared to dual energy x-ray absorptiometry (DXA as the referenced method. For this were used 16 gonadectomized obese cats (8 males and 8 females in a weight loss program. DXA, BIO, BIA and US were performed in the obese state (T0; obese animals, after 10% of weight loss (T1 and after 20% of weight loss (T2. Stepwise regression was used to analyze the relationship between the dependent variables (FM, LM determined by DXA and the independent variables obtained by BIO, BIA and US. The better models chosen were evaluated by a simple regression analysis and means predicted vs. determined by DXA were compared to verify the accuracy of the equations. Results The independent variables determined by BIO, BIA and US that best correlated (p?r2, 19 equations were selected (12 for FM, 7 for LM; however, only 7 equations accurately predicted FM and one LM of cats. Conclusions The equations with two variables are better to use because they are effective and will be an alternative method to estimate body composition in the clinical routine. For estimated lean mass the equations using body weight associated with biometrics measures can be proposed. For estimated fat mass the equations using body weight associated with bioimpedance analysis can be proposed.

    Introduction: Bioelectrical impedance analysis (BIA) is a useful tool to asses human body composition and nutrition status; multi-frequency BIA has a higher accuracy than single-frequency BIA. In our study a difference of impedance values (Z) at 5, 100 and 200 kHz and Z200/Z5 index between professional athletes and control group were determined. Methods: In this research 105 people were tested, divided into control group (72 people: 35 males and 37 females) and professional athletes (33 people: 16 males and 17 females). Impedance was measured at three frequency values - 5, 100 and 200 kHz; with received values the Z200/Z5 index was calculated. Results: In most compared subgroups impedance values showed significantly lower values in athletes than in control group (5 kHz - males: p=0.136, females: p=0.001, 100 kHz - males: p=0.039, females: pConclusion: Lower values of impedance and Z200/Z5 index indicates a better nutrition status and general health condition of athletes than in control group.

    This study aimed to compare the accuracy for predicting body composition using single-frequent segmental bioelectrical impedance analysis (BIA) between pre- and postmenopausal women. A total f 559 Japanese women aged 30-88yr were divided into 4 groups by questionnaire: natural menopause, pathological menopause, regular menstruation, or irregular menstruation. The measurement values by dual-energy X-ray absorptiometry were used as a reference of the body composition. In terms of the results, regardless of the menopausal status, BIA slightly but significantly overestimated the percentage of body fat (standard error of estimate: 5.3%-6.7%) and the leg lean soft tissue mass (LSTM; 5.1%-6.1%), and underestimated the LSTM in the whole body (6.2%-7.6%) and arm (2.8%-3.7%). The absolute values of the predictive error for leg LSTM were significantly higher in postmenopausal groups than in the premenopausal ones. The corresponding values for the whole body and arm LSTM, and the percentage of body fat were higher in premenopausal groups than in postmenopausal ones. In conclusion, the predictive accuracy of BIA for postmenopausal women is not inferior to that for premenopausal ones, unless we target the leg LSTM. PMID:25174687

  4. U.S. grants political asylum to woman who fled female genital mutilation.

    Fauziya Kasinga fled to the US from Togo in 1994 at the age of 17 years after an aunt forced her to marry a 45-year-old man with three wives. From the time of her arrival to the US in December 1994 to April 24, 1996, Kasinga was detained at two correctional facilities awaiting a decision by the US Board of Immigration Appeals (BIA) on her request for political asylum. That asylum was granted in a 11-1 decision issued on June 13 on the grounds of Kasinga's fear of being forced to undergo female genital mutilation (FGM) if sent back to Togo. This is the first time that the BIA has ruled that FGM can be grounds for asylum. 50% of women in Togo are estimated to have undergone FGM. The BIA decided that the young woman met the criteria for receiving refuge because she is a member of a particular social group, the unmutilated women of the Tchamba-Kunsuntu tribe who face but oppose FGM, which has a well-founded fear of persecution which is country wide. Moreover, Kasinga's husband has influence with the police in Togo, a rather small country. This decision not only sets precedent with regard to FGM, but also is the first gender-based asylum claim to be considered since the Immigration and Naturalization Service revised its guidelines in May 1995 to cover such persecution.

    AIM: Predictive equations for estimating body composition from bioelectrical impedance analysis (BIA) among Scandinavian children are lacking. In the present study, equations for estimation of fat-free body mass (FFM) and lean tissue mass (LTM) were developed and cross-validated from BIA using dual-energy X-ray absorptiometry (DXA) as the reference measurement of body composition. METHODS: The study population consisted of 49 girls and 52 boys aged 9-11 years from Malmö, Sweden. Bioelectrical impedance was measured between hand and foot at 50 kHz. Predictive equations were developed by multiple linear regression and cross-validated against DXA measurements of body composition. RESULTS: FFM was predicted from BIA and anthropometric variables with an adjusted R(2)= 0.95 and root mean square error (RMSE) = 0.84 kg, and LTM was predicted with an adjusted R(2)= 0.95 and RMSE = 0.87 kg. Cross-validation revealed a mean RMSE = 0.95 kg FFM and a mean RMSE = 0.96 kg LTM. Prediction of body composition from equationsdeveloped in previous literature was mixed when applied to the present cohort of children. CONCLUSIONS: FFM and LTM are predicted with sufficient accuracy at the population level. We recommend that the predictive equations developed in the present study are used in prepubescent European children aged 9-11 years only in order to minimize confounding of results because of possible differences in population samples.

    Background and Aims Bioelectrical impedance analysis (BIA) is a widely used technique to assess body composition and nutritional status. While bioelectrical values are affected by diverse variables, there has been little research on validation of BIA in acute illness, especially to understand prognostic significance. Here we report the use of BIA in acute febrile states induced by influenza. Methods Bioimpedance studies were conducted during an H1N1 influenza A outbreak in Venezuelan Amerindian villages from the Amazonas. Measurements were performed on 52 subjects between 1 and 40 years of age, and 7 children were re-examined after starting Oseltamivir treatment. Bioelectrical Impedance Vector Analysis (BIVA) and permutation tests were applied. Results For the entire sample, febrile individuals showed a tendency toward greater reactance (p=0.058) and phase angle (p=0.037) than afebrile individuals, while resistance and impedance were similar in the two groups. Individuals with repeated measurements showed significant differences in bioimpedance values associated with fever, including increased reactance (p<0.001) and phase angle (p=0.007), and decreased resistance (p=0.007) and impedance (p<0.001). Conclusions There are bioelectrical variations induced by influenza that can be related to dehydration, with lower extracellular to intracellular water ratio in febrile individuals, or a direct thermal effect. Caution is recommended when interpreting bioimpedance results in febrile states. PMID:25915945

    To assess the impact of air travel on swelling of the 'at risk' arm of women treated for breast cancer. Women treated for breast cancer from Canada (n = 60) and from within Australia (n = 12) attending a dragon boat regatta in Queensland, Australia participated. Women were measured within 2 weeks prior to their flight, on arrival in Queensland and, for 40 women travelling from Canada, measured again 6 weeks following return to Canada. Changes to extracellular fluid were measured using a single-frequency bioimpedance device (BIA). Each arm was measured separately using a standardized protocol to obtain the inter-limb impedance ratio. An increase in the ratio indicates accumulated fluid. Information regarding medical management of participants' breast cancer, use of compression garment and history of exercise were also obtained. For most women (95%), air travel did not adversely affect the impedance ratio. The BIA ratio of long-haul travellers was 1.007 +/- 0.065 prior to the flight and 1.006 +/- 0.087 following the flight. The ratio of short-haul travellers was 0.994 +/- 0.033 and following the flight was 1.001 +/- 0.038. Air travel did not cause significant change in BIA ratio in the 'at-risk' arm for the majority of breast cancer survivors who participated in dragon boat racing. Further research is required to determine whether these findings are generalizable to the population of women who have been treated for breast cancer. PMID:20180016

    Two manually guided brief interventions were evaluated with a randomized, controlled trial. Adolescents (aged 13-17 years) suspected of abusing alcohol and other drugs and their parent were randomly assigned to receive either a 2-session adolescent only (BI-A), 2-session adolescent and additional parent session (BI-AP), or assessment only control condition (CON). Adolescents were identified in a school setting, and the intervention was delivered by trained counselors. Outcome analyses (N = 284; 90% of those enrolled) of relative change (from intake to 12 months) and absolute status (at 12 months) revealed a general pattern of reductions in drug use behaviors, particularly with the cannabis outcome measures, in both active conditions (BI-A and BI-AP). Students in the control condition showed worse outcome compared with the BI-A and BI-AP groups. Among the 4 mediating variables measured at 6 months, use of additional services, motivation to change, and parenting practices had significant influences on 12-month outcome; problem-solving skills approached significance as a mediator. The potential value of a brief intervention for drug abusing adolescents is discussed. PMID:24955669

  11. What impact do Global Health Initiatives have on human resources for antiretroviral treatment roll-out? A qualitative policy analysis of implementation processes in Zambia

    Directory of Open Access Journals (Sweden)

    2009-02-01

    Full Text Available Abstract Background Since the beginning of the 21st century, development assistance for HIV/AIDS has increasingly been provided through Global Health Initiatives, specifically the United States Presidential Emergency Plan for AIDS Relief, the Global Fund to Fight HIV, TB and Malaria and the World Bank Multi-country AIDS Programme. Zambia, like many of the countries heavily affected by HIV/AIDS in southern Africa, also faces a shortage of human resources for health. The country receives significant amounts of funding from GHIs for the large-scale provision of antiretroviral treatment through the public and private sector. This paper examines the impact of GHIs on human resources for ART roll-out in Zambia, at national level, in one province and two districts. Methods It is a qualitative policy analysis relying on in-depth interviews with more than 90 policy-makers and implementers at all levels. Results Findings show that while GHIs do not provide significant funding for additional human resources, their interventions have significant impact on human resources for health at all levels. While GHIs successfully retrain a large number of health workers, evidence suggests that GHIs actively deplete the pool of skilled human resources for health by recruiting public sector staff to work for GHI-funded nongovernmental implementing agencies. The secondment of GHI staff into public sector facilities may help alleviate immediate staff shortages, but this practice risks undermining sustainability of programmes. GHI-supported programmes and initiatives add significantly to the workload of existing public sector staff at all levels, while incentives including salary top-ups and overtime payments mean that ART programmes are more popular among staff than services for non-focal diseases. Conclusion Research findings suggest that GHIs need to actively mediate against the potentially negative consequences of their funding on human resources for health. Evidence presented highlights the need for new strategies that integrate retraining of existing staff with longer-term staff development to ensure staff retention. The study results show that GHIs must provide significant new and longer-term funding for additional human resources to avoid negative consequences on the overall provision of health care services and to ensure sustainability and quality of programmes they support.

    Full Text Available Widespread Hunger and Malnutrition is highly prevalent in India. It should be a subject of shame for every Indian. The cost benefit analysis of National Food Security Bill has been attempted in this paper. Is this a necessity for the economy like India where widespread Hunger and malnutrition is a major problem? According to GHI India's rank is 63rd out of 78 countries. Different cost estimates of Food Security Bill and the cost of 'no food security' have been compared.FSB is the need of the hour but it will dwindle our Fiscal deficit. Research is needed to be done so as to minimize the cost of FSB. History proves that when the people are secure and have enough to feed themselves, they are the useful productive members of the economy. Even the rich countries also spends on the basic needs of their people.

    The report gathers the main outstanding facts which occurred in France in the field of hydrogen and fuel cells in 2010. After having noticed some initiatives (the Grenelle II law, an investment package, the new role of the CEA, the new role of the IFP), the report presents several projects and programs regarding hydrogen: ANR programs, creation of a national structure (the HyPaC platform), regional initiatives and local actions, colloquiums and meetings in France and in the world, research projects (photo-synthesis as a new electric energy source), a technical-economic investigation (HyFrance3), demonstrator projects (the Althytude project by GDF and Suez, the Plathee hybrid locomotive by the SNCF, the H2E project, the Zero CO2 sailing boat, and the Myrte project), educational applications, activity in small and medium-sized enterprises (CETH, SAGIM, HYCAN, McPhy, N-GHY).

  17. A Bayesian Model Committee Approach to Forecasting Global Solar Radiation

    CERN Document Server

    Lauret, Philippe; Muselli, Marc; David, Mathieu; Diagne, Hadja; Voyant, Cyril

    2012-01-01

    This paper proposes to use a rather new modelling approach in the realm of solar radiation forecasting. In this work, two forecasting models: Autoregressive Moving Average (ARMA) and Neural Network (NN) models are combined to form a model committee. The Bayesian inference is used to affect a probability to each model in the committee. Hence, each model's predictions are weighted by their respective probability. The models are fitted to one year of hourly Global Horizontal Irradiance (GHI) measurements. Another year (the test set) is used for making genuine one hour ahead (h+1) out-of-sample forecast comparisons. The proposed approach is benchmarked against the persistence model. The very first results show an improvement brought by this approach.

    An extraction/clean-up procedure by SFE was developed for isolating PAHs from liver samples for subsequent HPLC-FL determination of ten PAHs in the enriched extract. Recoveries (90-115%) and RSD % ({<=} 7.7) were satisfactory. When applied to 11 samples of bird of prey (Tyto alba) protected species and classified of special interest, from the Galicia (Northwest to Spain), benzo[ghi]perylene and indeno[1,2,3-cd]pyrene were undetectable; chrysene and benzo[a]pyrene are only detected in one sample; benzo[a]anthracene and benzo[k]fluoranthene are only quantified in one sample and benzo[b]fluoranthene in two samples. The other PAHs, anthracene, fluoranthene and pyrene are present in almost all the samples. (orig.)

    Polycyclic aromatic hydrocarbons (PAHs) were determined by high performance liquid chromatography (HPLC) method with fluorescence detection in rainbow trout fillets processed by traditional flue gas smoking and by liquid smoke flavourings, at low temperature (25 degrees C for 3h). Raw fillets were also investigated as control group. The following compounds, anthracene, fluoranthene, pyrene, benz(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene and benzo(ghi)perylene were detected in all samples and no significant difference (p>0.05) was found neither between fresh and processed samples nor between the two different smoking techniques, except for chrysene and benzo(b)fluoranthene. The results show that PAHs found in rainbow trout fillets could be considered as a consequence of environmental pollution and the mild smoking process described in the present study did not affect their concentrations.

    Supercritical fluid extraction was applied to the determination of naturally contaminated polycyclic aromatic hydrocarbons (PAHs) in bird tissue by liquid chromatography with fluorescence detection (LC-FL). Recoveries (> 90%) and relative standard deviations (< or = 7.7%) were satisfactory. The levels of 10 PAHs were analyzed in 6 classes of tissues (heart, liver, intestine, muscle, lung, and kidney) of 10 buzzards and 2 tawny owls, predatory birds from the Galicia (northwest Spain). The PAHs found most abundantly were pyrene, fluoranthene, benzo[a]anthracene, and anthracene. Chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[ghi]perylene, and indeno[1,2,3-cd]pyrene were not detected. Intestine, kidney, and lung were more polluted than other tissues.

    2015-10-01

    We present the general design features and preliminary performances of a new system for the simultaneous AMS-14C and IRMS ?13C and ?15N measurements on samples with masses in the ?g range. The system consists of an elemental analyzer (EA), a gas splitting unit (GSU), a IRMS system, a gas handling interface (GHI) and a sputtering ion source capable of accepting gaseous samples. A detailed description of the system and of the control software supporting unattended operation are presented together with the first performance tests carried out by analyzing samples with masses ranging from 8 ?gC to 2.4 mgC. The performances of the system were tested in term of stability of the ion beam extracted from the ion source, precision and accuracy of the results by comparing the measured isotopic ratios with those expected for reference materials.

    Full Text Available En el presente trabajo se expone el monitoreo de termokarts glaciarios y su relación e interacción con los eventos surges ocurridos en el glaciar cubierto Horcones Inferior (GHI). Este glaciar se encuentra ubicado a los 32º 41'S y 69º 57'W, al pie de la pared sur del C° Aconcagua, Parque Provincial [...] Aconcagua, en la Provincia de Mendoza, Argentina. El estudio fue llevado a cabo a través de la implementación de métodos indirectos de detección utilizando imágenes de los sensores Landsat y Aster durante el período 1997-2006. En el Glaciar Horcones Inferior "GHI", la superficie ocupada por los termokarst alcanza valores que varían entre el 4.3% y el 0% de la superficie total del glaciar, al finalizar un evento de surge. Las velocidades registradas en la superficie del glaciar cubierto arrojaron valores promedios entre 0.4 y 12 m/día. La metodología aplicada, con imágenes satelitales históricas, representa una herramienta fundamental para separar períodos de flujo glaciario catastróficos y no catastróficos. Abstract in english This work analyses the temporal evolution of thermokarst and their relationship to the surges in a reconstituted debris covered glacier.

The study and monitoring of the thermokarst was carried out applying indirect methods using Landsat and Aster images from 1997-2006. Detected percentages of thermokarst, in relation to the total glacial area, showed that they varied between 4.3% to 0% at the end of the surge event. The registered speeds of the glacier -on the glacial surface- reached averages of between 0.4 and 12 m/d. This methodology, with historical images from archives, represents a fundamental tool to separate catastrophic and non-catastrophic glacial flow periods.

    Full Text Available Natural abundance radiocarbon analysis facilitates distinct source apportionment between contemporary biomass/biofuel (14C "alive" versus fossil fuel (14C "dead" combustion. Here, the first compound-specific radiocarbon analysis (CSRA of atmospheric polycyclic aromatic hydrocarbons (PAHs was demonstrated for a set of samples collected in Lycksele, Sweden a small town with frequent episodes of severe atmospheric pollution in the winter. Renewed interest in using residential wood combustion (RWC means that this type of seasonal pollution is of increasing concern in many areas. Five individual/paired PAH isolates from three pooled fortnight-long filter collections were analyzed by CSRA: phenanthrene, fluoranthene, pyrene, benzo[b+k]fluoranthene and indeno[cd]pyrene plus benzo[ghi]perylene; phenanthrene was the only compound also analyzed in the gas phase. The measured ?14C for PAHs spanned from ?138.3‰ to 58.0‰. A simple isotopic mass balance model was applied to estimate the fraction biomass (fbiomass contribution, which was constrained to 71–87% for the individual PAHs. Indeno[cd]pyrene plus benzo[ghi]perylene had an fbiomass of 71%, while fluoranthene and phenanthrene (gas phase had the highest biomass contribution at 87%. The total organic carbon (TOC, defined as carbon remaining after removal of inorganic carbon fbiomass was estimated to be 77%, which falls within the range for PAHs. This CSRA data of atmospheric PAHs established that RWC is the dominating source of atmospheric PAHs to this region of the boreal zone with some variations among RWC contributions to specific PAHs.

  7. A transfer function for the prediction of gas hydrate inventories in marine sediments

    Full Text Available A simple prognostic tool for gas hydrate (GH quantification in marine sediments is presented based on a diagenetic transport-reaction model approach. One of the most crucial factors for the application of diagenetic models is the accurate formulation of microbial degradation rates of particulate organic carbon (POC and the coupled formation of biogenic methane. Wallmann et al. (2006 suggested a kinetic formulation considering the ageing effects of POC and accumulation of reaction products (CH4, CO2 in the pore water. This model is applied to data sets of several ODP sites in order to test its general validity. Based on a thorough parameter analysis considering a wide range of environmental conditions, the POC accumulation rate (POCar in g/m2/yr and the thickness of the gas hydrate stability zone (GHSZ in m were identified as the most important and independent controls for biogenic GH formation. Hence, depth-integrated GH inventories in marine sediments (GHI in g of CH4 per cm2 seafloor area can be estimated as:

    GHI = a · POCar · GHSZb · exp (– GHSZc/POCar/d + e

    with a = 0.00214, b = 1.234, c = –3.339,

            d = 0.3148, e = –10.265.

    The transfer function gives a realistic first order approximation of the minimum GH inventory in low gas flux (LGF systems. The overall advantage of the presented function is its simplicity compared to the application of complex numerical models, because only two easily accessible parameters need to be determined.

    Full Text Available Objetivo: Evaluar la composición corporal en un grupo de pacientes desnutridas con anorexia nerviosa, respecto de controles sanas, antes y después del soporte nutricional, mediante antropometría y bioimpedancia. Métodos: Estudio observacional prospectivo. Se realizó una antropometría completa y un a [...] nálisis de bioimpedancia a 12 mujeres con anorexia nerviosa restrictiva (24,5 años) al ingreso hospitalario y semanalmente durante la realimentación. El grupo control estuvo formado por 24 mujeres sanas (21 años). Se aplicaron los test t-Student, U-Mann-Whitney, t-Student para medidas repetidas o Wilcoxon. La concordancia entre antropometría y BIA se analizó mediante el coeficiente de correlación intraclase y Bland-Altman. Resultados: Las pacientes mejoraron significativamente todos los índices de composición corporal a lo largo de la estancia hospitalaria, aunque sus valores al alta siguieron siendo menores que los de las controles. La media de peso ganado fue 5,22 kg (DE: 1,42), de los que el 51,4% fueron masa grasa, con distribución central preferentemente. En las controles la ecuación de BIA que mejor concuerda con antropometría es la de Sun (CCI = 0,896); en las pacientes la concordancia fue más débil, al ingreso y al alta. Conclusiones: La realimentación produce una ganancia ponderal, fundamentalmente a expensas de masa grasa, con distribución central; no se consigue restablecer el estado nutricional. La concordancia entre antropometría y bioimpedancia para el estudio de la composición corporal es aceptable, especialmente en sujetos sanos. Se recomienda emplear antropometría, si no se dispone de BIA vectorial o algún método gold estandard para el análisis de la composición corporal, en casos de alteraciones importantes en la composición corporal y/o el balance hídrico. Abstract in english Objective: To assess the body composition in a group of malnourished patients with anorexia nervosa as compared to healthy controls, before and after nutritional support, by means of anthropometry and bioimpedance. Methods: Prospective observational study. Complete anthropometry was performed as wel [...] l as bioimpedance analysis in 12 women (24.5 years) with restrictive anorexia nervosa at hospital admission and weekly thereafter during re-feeding. The control group was formed by 24 healthy women (21 years). The Student's t test, the Mann-Whitney U test, the Student's t test for repeated measurements, and the Wilcoxon's test were applied. The level of agreement between anthropometry and BIA was calculated by the interclass correlation coefficient and the Bland-Altman s test. Results: The patients had significant improvements in all indexes of body composition throughout their hospital staying although their values at discharge still were lower than those of the control subjects. The average weight gain was 5.22 kg (SD: 1.42), of which 51.4% was fat mass, preferentially centrally distributed. In the control subjects, the BIA equation that correlated the best with anthropometrics was Sun s equation (CCI = 0.896); in the patients, the level of agreement was weaker, both at hospital admission and at hospital discharge. Conclusions: Re-feeding produces weight gain, essentially at the expense of fat mass, which is centrally distributed; the nutritional status is not reestablished. The level of agreement between anthropometry and bioimpedance for studying body composition is acceptable, especially in healthy subjects. In those cases with severe changes in body composition and/or water balance, anthropometry is recommended when vectorial BIA or some other gold standard method are not available for the analysis of body composition.

Métodos: Se realizó un estudio con un diseño en doble fase. Se estudiaron 329 chicas y 96 chicos (de 12-18 años) procedentes de una muestra inicial de 2967 adolescentes. Se calcularon el índice de masa corporal (IMC), el porcentaje de masa grasa (% MG(BIA)), la circunferencia de la cintura, los cocientes cintura-talla y cintura-cadera. Se administraron el Eating Attitudes Test, el Youth's Inventory-4 y un cuestionario para evaluar influencia sociocultural. Resultados: El 34,7% de las chicas y el 53,6% de los chicos con riesgo de TCA presentan sobrepeso (incluyendo obesidad). La frecuencia de sobrepeso es significativamente más alta en las chicas del grupo de riesgo de TCA que las del grupo control. En las adolescentes, el aumento de un punto en el IMC o en el % MG(BIA) incrementa el riesgo de estar en riesgo de TCA en 12% (3,0-19,0) y 4% (0,0-8,0), respectivamente; un incremento en el cociente cintura-cadera se asocia negativamente con el riesgo de TCA. Fumar, presentar síntomas de distimia y de trastornos de ansiedad generalizada también se asociaron con la probabilidad de estar en riesgo de TCA, en las adolescentes.

The BMI, percentage of fat mass estimated by bioimpedance (FM(BIA)), waist circumference, waist-to-height ratio, and waist-to-hip ratio (WHipr) were calculated. The Eating Attitudes Test, Youth's Inventory-4 and a questionnaire to evaluate social influences were administered. Results: A total of 34.7% of girls and 53.6% of boys at risk of ED were overweight (including obesity). For girls, overweight frequency was significantly higher in risk ED group than in control group. Increases of one point in the BMI or FM(BIA) increased the probability of being at risk of ED by 12% (3.0-19.0) and 4% (0.0-8.0), respectively. An increase in Whipr was negatively associated with ED risk. Smoking and symptoms of dysthymia and the genralized anxiety disorder also increase the probability of being at risk of ED in adolescent girls. In adolescent boys, these relations were not observed. Conclusions: The higher BMI and the percentage of FM(BIA) are associated with greater risk of ED in adolescent girls, when psychological factors are present. Increases in the WHipr, characteristic of childhood body is negatively associated with that risk.

    Full Text Available La determinación del porcentaje de masa grasa en pacientes con lesión medular crónica (LMC) resulta de interés por la alta morbimortalidad cardiovascular que presenta este grupo. En el caso de deportistas, además, permitiría optimizar su rendimiento deportivo. Por consiguiente, el presente estudio s [...] e planteó como primer objetivo comparar diferentes métodos de estudio del porcentaje de masa grasa de deportistas con LMC. Y como objetivo secundario, identificar alguna ecuación que permita predecir los niveles de masa grasa de manera más económica, sencilla, rápida y no invasiva. Se diseño un estudio observacional y transversal en el que participaron voluntariamente 8 deportistas varones con LMC a nivel o por debajo de T5 que compiten a nivel nacional. El porcentaje de masa grasa corporal de los participantes se determinó mediante tres metodologías: densitometría (DEXA), antropometría convencional (Ecuación de Siri) e impedancia bioeléctrica (BIA). Este protocolo fue aprobado por un Comité de Ética Institucional. El porcentaje de masa grasa presentado por jugadores de baloncesto en silla de ruedas tras someterse al método de referencia (DEXA) fue del 28,76±9,16%. El análisis de concordancia de Bland-Altman entre métodos sugiere que tanto la antropometría convencional como la BIA subestiman el porcentaje de masa grasa de deportistas con LMC. la ecuación de predicción obtenida fue: Masa Grasa (%)= 1,9197 (pliegue tríceps (mm)) + 6,5063. Tanto las técnicas antropométricas convencionales como la propia BIA subestiman la masa grasa en deportistas con LMC. Asimismo se ha identificado una ecuación de regresión para la predicción del porcentaje de masa grasa de bajo coste y aplicable en cualquier entorno.

F [...] or the reasons already mentioned, the current study was designed to compare different methods for assessing FM in athletes with SCI. A secondary objective was to identify a predictive equation for FM in this group that is easily reproducible elsewhere. A total of 8 male athletes with complete SCI at or below the 5th thoracic level (T5) competing in a national league volunteered for this study. The percentage of FM was assessed by three different methods: conventional anthropometry (Siri equation), bioelectrical impedance analysis (BIA) and densitometry (DEXA). This research was conducted in full accordance with ethical principles, including the World Medical Association Declaration of Helsinki (version, 2002). Furthermore, the present protocol was approved by an Institutional Ethics Committee. Mean percentage of FM assessed by DXA was 28.76±9.16%. Moreover, Bland-Altman plots suggested conventional anthropometry and BIA underestimated fat mass percentage in this group. Lastly, a predictive equation for fat mass was established as follows: FM (%)=1.9197 (triceps skinfold thickness (mm))+6.5063. It was concluded that both conventional anthropometry and BIA underestimated fat mass in athletes with chronic SCI. Furthermore, a predictive equation of fat mass was recommended for this group due to its low cost and wide availability in any clinical setting.

    Full Text Available Background: Overweight and eating disorder (ED are major public health problems in adolescents. Aims: To assess the association of overweight, body composition and anthropometric characteristics with the probability being at risk of ED. Methods: A two-phase study was used. 329 girls and 96 boys (aged 12-18 years from an initial sample of 2967 adolescents were studied. The BMI, percentage of fat mass estimated by bioimpedance (FM(BIA, waist circumference, waist-to-height ratio, and waist-to-hip ratio (WHipr were calculated. The Eating Attitudes Test, Youth's Inventory-4 and a questionnaire to evaluate social influences were administered. Results: A total of 34.7% of girls and 53.6% of boys at risk of ED were overweight (including obesity. For girls, overweight frequency was significantly higher in risk ED group than in control group. Increases of one point in the BMI or FM(BIA increased the probability of being at risk of ED by 12% (3.0-19.0 and 4% (0.0-8.0, respectively. An increase in Whipr was negatively associated with ED risk. Smoking and symptoms of dysthymia and the genralized anxiety disorder also increase the probability of being at risk of ED in adolescent girls. In adolescent boys, these relations were not observed. Conclusions: The higher BMI and the percentage of FM(BIA are associated with greater risk of ED in adolescent girls, when psychological factors are present. Increases in the WHipr, characteristic of childhood body is negatively associated with that risk.Introducción: El sobrepeso y los Trastornos de la Conducta Alimentaria (TCA son problemas importantes de salud pública entre los adolescentes.

    This review aims to identify, assess and analyse the evidence on equity in the distribution of public health sector expenditure in low- and middle-income countries. Four bibliographic databases and five websites were searched to identify quantitative studies examining equity in the distribution of public health funding in individual countries or groups of countries. Two different types of studies were identified: benefit incidence analysis (BIA) and resource allocation comparison (RAC) studies. Quality appraisal and data synthesis were tailored to each study type to reflect differences in the methods used and in the information provided. We identified 39 studies focusing on African, Asian and Latin American countries. Of these, 31 were BIA studies that described the distribution, typically across socio-economic status, of individual monetary benefit derived from service utilization. The remaining eight were RAC studies that compared the actual expenditure across geographic areas to an ideal need-based distribution. Overall, the quality of the evidence from both types of study was relatively weak. Looking across studies, the evidence confirms that resource allocation formulae can enhance equity in resource allocation across geographic areas and that the poor benefits proportionally more from primary health care than from hospital expenditure. The lack of information on the distribution of benefit from utilization in RAC studies and on the countries' approaches to resource allocation in BIA studies prevents further policy analysis. Additional research that relates the type of resource allocation mechanism to service provision and to the benefit distribution is required for a better understanding of equity-enhancing resource allocation policies.

    Full Text Available OBJECTIVE: Body composition analysis is useful technique for assessing hydration, nutritional status and predicting clinical outcomes. Bioimpedance analysis (BIA is a cheap and noninvasive tool for monitoring body composition but needs some improvements regarding measurement methods. We aimed to fi nd out if body position has an effect on the BIA results. MATERIAL and METHODS: Personal characteristics including age, gender, height, weight and blood pressure were recorded. Hydration and nutritional status measured by body composition monitor in supine and standing positions consequently for each individual. RESULTS: Two hundred and one populations from various region in Turkey, 61% (n: 123 male, mean age was 46.3±12 years (18-76 of age, participated in this crossectional study. From supine to standing positions overhydration and extracellular water (ECW were increased from 0.04±1.08 and 17.69±2.92 to 0.46±1.05 L and 17.84±2.90 L while intracellular water (ICW decreased from 22.55±4.35 to 22.04±4.28 L signifi cantly. Systolic and diastolic blood pressures were 131.3±18.1 and 75.1±12 decreased to 127.0±16.0 and 72.2±9.0 mmHg in supine to standing positions (p> 0.05. CONCLUSION: Supine and standing positions could affect the volume parameters of BIA due to shift of ECW and ICW by gravity but nutritional parameters also changes signifi cantly. Protocols should be re evaluated in order to get more accurate results in bioimpedance measurements.

    The physiological well-being or condition of fish is most commonly estimated from aspects of individual morphology. However, these metrics may be only weakly correlated with nutritional reserves stored as lipid, the primary form of accumulated energy in fish. We constructed and evaluated bioelectrical impedance analysis (BIA) models as an alternative method of assessing condition in amphidromous Dolly Varden Salvelinus malma collected from nearshore estuarine and lotic habitats of the Alaskan Arctic. Data on electrical resistance and reactance were collected from the lateral and ventral surfaces of 192 fish, and whole-body percent lipid and moisture content were determined using standard laboratory methods. Significant inverse relationships between temperature and resistance and reactance prompted the standardization of these data to a constant temperature using corrective equations developed herein. No significant differences in resistance or reactance were detected among spawning and nonspawning females after accounting for covariates, suggesting that electrical pathways do not intersect the gonads. Best-fit BIA models incorporating electrical variables calculated from the lateral and ventral surfaces produced the strongest associations between observed and model-predicted estimates of proximate content. These models explained between 6% and 20% more of the variability in laboratory-derived estimates of proximate content than models developed from single-surface BIA data and 32% more than models containing only length and weight data. While additional research is required to address the potential effects of methodological variation, bioelectrical impedance analysis shows promise as a way to provide high-quality, minimally invasive estimates of Dolly Varden lipid or moisture content in the field with only small increases in handling time.

    Pyronaridine tetraphosphate (1) is a well-known antimalarial drug. However, it required a carefully optimized production process for the manufacture of pyronaridine tetraphosphate. Each step of its manufacturing process was reinvestigated. For the cyclization of 4-chloro-2-(6-methoxy-pyridin-3-yl-amino)-benzoic acid 6 to 7,10-dichloro-2-methoxybenzo[b]-1,5-naphthyridine 5, an improved process was developed to eliminated critical process impurity (BIA). By the redesign of the formation of triphosphate salt, the purity as API grade was increased. Thus, a robust manufacturing process with an acceptable process performance has been developed to produce high quality pyronaridine tetraphosphate.

    The ELF or fluorescence-labeled enzyme activity (FLEA) technique is a culture-independent single-cell tool for assessing plankton enzyme activity in close-to-in situ conditions. We demonstrate that single-cell FLEA quantifications based on two-dimensional (2D) image analysis were biased by up to one order of magnitude relative to deconvolved 3D. This was basically attributed to out-of-focus light, and partially to object size. Nevertheless, if sufficient cells were measured (25-40 cells), bia...

    Anti-predator responses by ungulates can be based on habitat features or on the near-imminent threat of predators. In dense forest, cues that ungulates use to assess predation risk likely differ from half-open landscapes, as scent relative to sight is predicted to be more important. We studied, in the Bia?owie?a Primeval Forest (Poland), whether perceived predation risk in red deer (Cervus elaphus) and wild boar (Sus scrofa) is related to habitat visibility or olfactory cues of a predator.

    2000-01-01

    Full Text Available Prolonged total food deprivation in non-obese adults is rare, and few studies have documented body composition changes in this setting. In a group of eight hunger strikers who refused alimentation for 43 days, water and energy compartments were estimated, aiming to assess the impact of progressive starvation. Measurements included body mass index (BMI, triceps skinfold (TSF, arm muscle circumference (AMC, and bioimpedance (BIA determinations of water, fat, lean body mass (LBM, and total resistance. Indirect calorimetry was also performed in one occasion. The age of the group was 43.3±6.2 years (seven males, one female. Only water, intermittent vitamins and electrolytes were ingested, and average weight loss reached 17.9%. On the last two days of the fast (43rd-44th day rapid intravenous fluid, electrolyte, and vitamin replenishment were provided before proceeding with realimentation. Body fat decreased approximately 60% (BIA and TSF, whereas BMI reduced only 18%. Initial fat was estimated by BIA as 52.2±5.4% of body weight, and even on the 43rd day it was still measured as 19.7±3.8% of weight. TSF findings were much lower and commensurate with other anthropometric results. Water was comparatively low with high total resistance, and these findings rapidly reversed upon the intravenous rapid hydration. At the end of the starvation period, BMI (21.5±2.6 kg/m² and most anthropometric determinations were still acceptable, suggesting efficient energy and muscle conservation. Conclusions: 1 All compartments diminished during fasting, but body fat was by far the most affected; 2 Total water was low and total body resistance comparatively elevated, but these findings rapidly reversed upon rehydration; 3 Exaggerated fat percentage estimates from BIA tests and simultaneous increase in lean body mass estimates suggested that this method was inappropriate for assessing energy compartments in the studied population; 4 Patients were not morphologically malnourished after 43 days of fasting; however, the prognostic impact of other impairments was not considered in this analysis.

    2014-01-01

    For 3-year-old children suitable methods to estimate body composition are sparse. We aimed to develop predictive equations for estimating fat-free mass (FFM) from bioelectrical impedance (BIA) and anthropometry using dual-energy X-ray absorptiometry (DXA) as reference method using data from 99 healthy 3-year-old Danish children. Predictive equations were derived from two multiple linear regression models, a comprehensive model (height(2)/resistance (RI), six anthropometric measurements) and a simple model (RI, height, weight). Their uncertainty was quantified by means of 10-fold cross-validation approach. Prediction error of FFM was 3.0% for both equations (root mean square error: 360 and 356 g, respectively). The derived equations produced BIA-based prediction of FFM and FM near DXA scan results. We suggest that the predictive equations can be applied in similar population samples aged 2-4 years. The derived equations may prove useful for studies linking body composition to early risk factors and early onset of obesity.

    This work proposes the application of batch-injection analysis with amperometric detection to determine the antioxidant capacity of real samples based on the measurement of DPPH radical consumption. The efficient concentration or EC50 value corresponds to the concentration of sample or standard required to scavenge 50% DPPH radicals. For the accurate determination of EC50, samples were incubated with DPPH radical for 1h because many polyphenolic compounds typically found in plants and responsible for the antioxidant activity exhibit slow kinetics. The BIA system with amperometric detection using a glassy-carbon electrode presented high precision (RSD = 0.7%, n = 12), low detection limit (1 ?mol L(-1)) and selective detection of DPPH (free of interferences from antioxidants). These contributed to low detection limits for the antioxidant (0.015 and 0.19 ?mol L(-1) for gallic acid and butylated hydroxytoluene, respectively). Moreover, BIA methods show great promise for portable analysis because battery-powered instrumentation (electronic micropipette and potentiostats) is commercially available. PMID:26304399

    Sarcopenia is a progressive and generalized loss of skeletal muscle mass (SM) and function which can also be found in obese adults. The aim of the study was to evaluate the prevalence of sarcopenia in 1 245 obese women (18 - 67 years, weight 114.7±24.5 kg; BMI 44.1±9.2 fat mass 49.0±6.2%) from Southern Italy. Body composition was evaluated by bioimpedance analysis (BIA) and SM calculated by using Janssen's equation; therefore the sex-specific cut-off points of percentage skeletal muscle index were used. The whole population was divided in two age groups: A (18-40 years; n. 808; weight 115.4±23.5 kg; BMI 43.8±8.8 kg/m2) and B (41-67 years; n. 438; weight 113.4±26.3 kg; BMI 44.8±9.9 kg/m2). In all the sample there was 2.7% moderate and 0.6% severe sarcopenia; in group A, 1.9% moderate and 0.6% severe sarcopenia whilst in group B 4.3% moderate and 0.7% severe sarcopenia. The results of our study suggest that, based on a screening examination by BIA, moderate/severe sarcopenia can be detected in an unselected middle-aged obese population. Further studies are required to clarify the diagnosis with functional tests.

  2. A study of percentage body fat in children via dual energy X-ray absorptiometry (DEXA)

    International Nuclear Information System (INIS)

    Percentage body fat was measured using dual energy X-ray absorptiometry (DEXA), bioelectrical impedance analysis (BIA) and skin fold calipers on 26 children (nine in obesity group, 12 in healthy group and 5 in steroid treated group). Mean percent body fat did not differ significantly between methods in the whole subjects as well as the healthy group and the steroid treated group. However, the mean percent body fat using skin fold caliper was higher for the obesity group than the other two. The measurements of all cases in the obesity group by DEXA were higher than those of BIA. There were high correlations among the percent body fat obtained by each technique. According to the analysis of mean regional percent fat, the percent fat of legs was the highest in the healthy and steroid treated group, while there was no regional difference in the obesity group. It should be possible to classify each case in the obesity group into upper segment and lower segment obesity by DEXA. (author)

    Inflammatory bowel diseases (IBD) are characterised by periods of disease activity and period with disease in remission. In Denmark all patients are seen in hospital settings. The aim of this study was to introduce a nurse-led phone service for stable patients replacing annual visits. The study originated from an outpatient cohort of 1,600 patients with IBD. A research protocol was determined before the intervention was launched, which included surveys among the patients before the intervention, after the intervention, collection of longitudinal data in a three year period, and a clinical audit. Budget impact analysis (BIA) and cost-effectiveness analysis (CEA) were done. Furthermore, the staff evaluated the process. Almost 30% (n = 474) of the total cohort was enrolled in the service. Eighty-seven per cent of the patients welcomed the phone service beforehand. After implementation, 94% of the patients included were pleased with the service. The programme has shortened the waiting time for most other services, but no improvement in the workload was observed. The BIA showed limited savings. The CEA showed an annual saving of 100€ per patient when using the annual phone service over routine visits. In conclusion, changing the method of contact from routine annual visits to annual phone calls from a nurse was feasible and well accepted for stable patients with IBD. The benefits of the service were most marked for the patients.

  4. Language control in bilingual language comprehension: evidence from the maze task.

    2015-01-01

    Most empirical evidence on switch costs is based on bilingual production and interpreted as a result of inhibitory control. It is unclear whether such a top-down control process exists in language switching during comprehension. This study investigates whether a non-lexical switch cost is involved in reading code-switched sentences and its relation to language dominance with cross-script bilingual readers. A maze task is adopted in order to separate top-down inhibitory effects, from lexical effects driven by input. The key findings are: (1) switch costs were observed in both L1-L2 and L2-L1 directions; (2) these effects were driven by two mechanisms: lexical activation and inhibitory control; (3) language dominance modulated the lexical effects, but did not affect the inhibitory effects. These results suggest that a language control mechanism is involved in bilingual reading, even though the control process is not driven by selection as in production. At the theoretical level, these results lend support for the Inhibitory Control model during language switching in comprehension; while the BIA/BIA+ model needs to incorporate a top-down control mechanism to be able to explain the current findings.

    Dual X-ray absorptiometry (DXA) performs noninvasive assessment of bone and soft tissue with high precision. However, soft tissue algorithms assume that 73.2% of the lean body mass is water, a potential source of error in fluid retention. We evaluated DXA (model QDR-2000; Hologic Inc, Waltham, MA), bioelectrical impedance analysis (BIA), and simple anthropometry in 19 patients (9 women and 10 men, mean age 46 y) before and after hemodialysis, removing 0.9-4.3 L (x: 2.8L) of ultrafiltrate. The reduction in fat-free mass (FFM) measured by DXA was highly correlated with the ultrafiltrate, as determined by the reduction in gravimetric weight (r = 0.975, P <0.0001; SEE: 233 g), whereas BIA was considerably less accurate in assessing FFM reductions (r = 0.66, P <0.01; SEE: 757 g). Lumbar bone mineral density (BMD) was unaffected by dialysis, as were whole-body fat and BMD. Whole-body bone mineral content, however, was estimated to be 0.6% lower after dialysis. None of the simple anthropometric measurements correlated significantly with the reduction in FFM. In an unmodified clinical setting, DXA appears to be superior to other simple noninvasive methods for determining body composition, particularly when the emphasis is on repeated measurements.

    The Bia?owie?a Workshops on Geometric Methods in Physics, which are hosted in the unique setting of the Bia?owie?a natural forest in Poland, are among the most important meetings in the field. Every year some 80 to 100 participants from both the mathematics and physics world join to discuss new developments and to exchange ideas. The current volume was produced on the occasion of the 32nd meeting in 2013. It is now becoming a tradition that the Workshop is followed by a School on Geometry and Physics, which consists of advanced lectures for graduate students and young researchers. Selected speakers at the 2013 Workshop were asked to contribute to this book, and their work was supplemented by additional review articles. The selection shows that, despite its now long tradition, the workshop remains at the cutting edge of research. The 2013 Workshop also celebrated the 75th birthday of Daniel Sternheimer, and on this occasion the discussion mainly focused on his contributions to mathematical physics such as ...

    Mercury content have been determined in 59 composite samples (from 3 to 6 fruit bodies per sample) of Common Chanterelle collected near the towns of Hel, Ciechocinek and Zakopane, and in Bialowieza Forest. Total mercury have been determined by cold-vapor atomic absorption spectrometry (CV-AAS) using validated analytical method with amalgamation on golden wool and further desorption of mercury (analyzer MA-2000). Mercury content of the dried fruit bodies of Common Chanterelle depending on the site ranged from 29 for the outskirts of the Ciechocinek to 46 ng/g for the area of Bia?owieska Forest. A meal made of 300 g of fresh fruit bodies of Common Chanterelle will result in intake of 0.87 (Ciechocinek) to 1.4 microg Hg (Bia?owieska Forest), while eating daily Common Chanterelle at this rate within a week will result in intake from 6.1 to 9.8 microg Hg on an average, respectively. These assessed doses of mercury intake are only small portions of reference dose (RfD) and PTWI for mercury. PMID:20839460

  8. Biodiversity Impact Assessment of roads: an approach based on ecosystem rarity

    International Nuclear Information System (INIS)

    Biodiversity has become one of the central environmental issues in the framework of recent policies and international conventions for the promotion of sustainable development. The reduction of habitat worldwide is currently considered as the main threat to biodiversity conservation. Transportation infrastructures, and above all road networks, are blamed for highly contributing to the decrease in both the quantity and the quality of natural habitat. Therefore, a sound Biodiversity Impact Assessment (BIA) in road planning and development needs to be coupled to other commonly considered aspects. This paper presents an approach to contribute to BIA of road projects that focuses on one type of impact: the direct loss of ecosystems. The first step consists in mapping the different ecosystem types, and in evaluating their relevance for biodiversity conservation. This is based on the assessment of ecosystem's rarity. Rarity is a measure of how frequently an ecosystem type is found within a given area. Its relevance is confirmed by the fact that the protection of rare ecosystems is often considered as the single most important function of biodiversity conservation. Subsequently, the impact of a road project can be quantified by spatially computing the expected losses of each ecosystem type. To illustrate the applicability of the methodology, a case study is presented dealing with the assessment of alternative routes for a highway development in northern Italy

    Full Text Available Objectives: The purpose of this investigation was to determine the effect of maximal exercise on percent body fat (%BF using bioelectrical impedance analysis in highly active male athletes at university. Design: The subjects of the study consisted of fifty-two (52 males with mean age of 21.68±1.66 years old, height of 164.46±5.21cm and weight of 57.69±6.61kg. All of the subjects joined the study voluntarily and were students in Akdeniz University School of Physical Education and Sport. Methods: All participants made two visits to the laboratory on separate days. On the first visit, anthropometric measurements were collected, orientation with the respiratory metabolic mouthpiece and treadmill was provided. During the second visit subjects exercised on a treadmill at different workloads in order to familiarize them to the treadmill.

    Full Text Available OBJECTIVE: To characterize the clinical and nutritional impact of coeliac disease (gluten-sensitive enteropathy among Saharawi children living as refugees in Algeria. METHODS: A total of 65 Saharawi children with coeliac disease were compared with 71 age-matched non-coeliac controls. For each participant, the clinical history was taken and a clinical examination, non-quantitative 24-hour dietary recall, anthropometric and skinfold measurements, bioelectric impedance analysis (BIA of body composition, and venous blood sampling for haemoglobin determination were performed. RESULTS: Gluten-containing food, especially bread, was the staple diet of Saharawi children. Abdominal pain and distension were significantly commoner among children with coeliac disease than in controls ( P < 0.05. The mean height-for-age was significantly lower in such children than in controls (-2.5 + 1.4 units vs -1.8 + 1.3 units, respectively, P < 0.01. No significant differences were found for either skinfold or BIA measurements. Haemoglobin values tended to be lower in children with coeliac disease than in controls. CONCLUSIONS: Coeliac disease has a negative effect on the health status of Saharawi refugee children. Because of the high prevalence of the condition in the Saharawi, a specific programme for treating all affected individuals should be established. Further studies are required to quantify the impact of coeliac disease in other areas of the developing world.

  17. Validation of the National Solar Radiation Database (NSRDB) (2005-2012): Preprint

    Publicly accessible, high-quality, long-term, satellite-based solar resource data is foundational and critical to solar technologies to quantify system output predictions and deploy solar energy technologies in grid-tied systems. Solar radiation models have been in development for more than three decades. For many years, the National Renewable Energy Laboratory (NREL) developed and/or updated such models through the National Solar Radiation Data Base (NSRDB). There are two widely used approaches to derive solar resource data from models: (a) an empirical approach that relates ground-based observations to satellite measurements and (b) a physics-based approach that considers the radiation received at the satellite and creates retrievals to estimate clouds and surface radiation. Although empirical methods have been traditionally used for computing surface radiation, the advent of faster computing has made operational physical models viable. The Global Solar Insolation Project (GSIP) is an operational physical model from the National Oceanic and Atmospheric Administration (NOAA) that computes global horizontal irradiance (GHI) using the visible and infrared channel measurements from the Geostationary Operational Environmental Satellites (GOES) system. GSIP uses a two-stage scheme that first retrieves cloud properties and then uses those properties in the Satellite Algorithm for Surface Radiation Budget (SASRAB) model to calculate surface radiation. NREL, the University of Wisconsin, and NOAA have recently collaborated to adapt GSIP to create a high temporal and spatial resolution data set. The product initially generates the cloud properties using the AVHRR Pathfinder Atmospheres-Extended (PATMOS-x) algorithms [3], whereas the GHI is calculated using SASRAB. Then NREL implements accurate and high-resolution input parameters such as aerosol optical depth (AOD) and precipitable water vapor (PWV) to compute direct normal irradiance (DNI) using the DISC model. The AOD and PWV, temperature, and pressure data are also combined with the MMAC model to simulate solar radiation under clear-sky conditions. The current NSRDB update is based on a 4-km x 4-km resolution at a 30-minute time interval, which has a higher temporal and spatial resolution. This paper demonstrates the evaluation of the data set using ground-measured data and detailed evaluation statistics. The result of the comparison shows a good correlation to the NSRDB data set. Further, an outline of the new version of the NSRDB and future plans for enhancement and improvement are provided.

  18. Compound-specific radiocarbon analysis of atmospheric PAH from a wood smoke-impacted city in Northern Sweden

    International Nuclear Information System (INIS)

    Full text: Atmospheric polycyclic aromatic hydrocarbons (PAHs) are ubiquitous due to their emission from a variety of combustion sources including motor vehicle exhaust and other fossil fuel combustion and biomass burning. Their potential to detrimentally impact human and ecological health makes it vital to apportion these compounds to emission sources. PAHs also have a wide range in volatility and can be present in both the gas and particulate phase in the atmosphere. However, PAHs present in high concentrations in the atmosphere are not source-specific and can be difficult to trace back to their original emission sources. Natural abundance radiocarbon analysis offers a trusted method for determining the fraction of modern versus fossil carbon and recent advances in micro-scale techniques have opened the door for compound class-specific radiocarbon analysis (CCSRA) of organic compounds at the low levels present in environmental samples. Atmospheric levels of PAHs provide a particular challenge due to difficulties in obtaining a sample with sufficient mass for radiocarbon analysis. Initial studies in Europe and Japan have shown a wide range of biomass burning contribution from 10 % of pooled PAHs for two background sites in south Europe to up to 45 % in Tokyo and 50 % at a background site in Sweden. Compound-specific radiocarbon analysis (CSRA) of atmospheric PAHs would further enhance the understanding of emission source impacts on ambient concentrations and has not been previously reported. In this study, CSRA was applied to a set of atmospheric samples collected in Lycksele, a city in Northern Sweden which has frequent episodes of severe atmospheric pollution in the winter. Previous studies carried out in the city have shown that wood combustion for residential heating has a large impact on atmospheric aerosol followed by motor vehicle emissions. This combination provided an ideal location for CSRA to apportion atmospheric PAHs between fossil fuel combustion and wood smoke. In order to maximize sample collection mass, a high volume total suspended particulate matter (TSP) sampler loaded with quartz fiber filters for PM collection and PUFs (polyurethane foam) for volatile species was used in this study. Five different particulate PAH samples were analyzed by CSRA including: phenanthrene, fluoranthene, pyrene, benzo[b+k]fluoranthene and indeno[cd]pyrene+benzo[ghi]perylene whereas phenanthrene was the only compound also analyzed in the gas phase. The percentage wood smoke contribution ranged from 70 % for indeno[cd]pyrene+benzo[ghi]perylene to 87 % for the PUF phenanthrene and particulate pyrene. There was a distinct molecular-weight trend (r2 = 0.68) to the fraction wood smoke contribution with higher contribution for the lower molecular-weight PAHs. (author)

Abstract in english This work aims to communicate the determination of estrogen receptor beta (ER?) in mammary tumors of 34 canine patients whose evolution after eighteen months post surgery was known. Its presence was associated with clinical staging of patients, histological type, histological grading of the malignan [...] cy, and evolution. Immunostaining was performed by biotin-streptavidin-peroxidase system. Positive ER? immunostaining was observed in nuclei of carcinoma cells, myoepithelial cells and chondrocites. It was determined the percentage of nuclei immunolabeled according to histological type (simple carcinoma: 51%, complex carcinoma: 61%, mixed carcinoma: 63%), histologic grade of malignancy (GHI: 60% and GHII: 61%), the clinical stage (ECI: 68%, ECII: 56%, ECIII: 59%, ECIV: 58% and ECV 58%) and in accordance with survival at 18 months (live: 61% and dead: 60%). These results show higher percentages in groups of better prognosis (although no significant differences were established) in coincidence with the opinions expressed by others, except in reference to the histological grade of malignancy. These conflicting data suggest that further analysis to assess ER? prognostic potential in canine mammary tumors is needed.

    Bacterial flagellin is perceived as a microbe (or pathogen)-associated molecular pattern (MAMP or PAMP) by the extracellular pattern recognition receptors, FLS2 and TLR5, of plants and mammals respectively. Flagellin accidently translocated into mammalian cells by pathogen type III secretion systems (T3SSs) is recognized by nucleotide-binding leucine-rich repeat receptor NLRC4 as a pattern of pathogenesis and induces a death-associated immune response. The non-pathogen Pseudomonas fluorescens Pf0-1, expressing a Pseudomonas syringae T3SS, and the plant pathogen P. syringae pv. tomato DC3000 were used to seek evidence of an analogous cytoplasmic recognition system for flagellin in the model plant Nicotiana benthamiana. Flagellin (FliC) was secreted in culture and translocated into plant cells by the T3SS expressed in Pf0-1 and DC3000 and in their ?flgGHI flagellar pathway mutants. ?fliC and ?flgGHI mutants of Pf0-1 and DC3000 were strongly reduced in elicitation of reactive oxygen species production and in immunity induction as indicated by the ability of challenge bacteria inoculated 6 h later to translocate a type III effector-reporter and to elicit effector-triggered cell death. Agrobacterium-mediated transient expression in N. benthamiana of FliC with or without a eukaryotic export signal peptide, coupled with virus-induced gene silencing of FLS2, revealed no immune response that was not FLS2 dependent. Transiently expressed FliC from DC3000 and Pectobacterium carotovorum did notinduce cell death in N. benthamiana, tobacco or tomato leaves. Flagellin is the major Pseudomonas?MAMP perceived by N. benthamiana, and although flagellin secretion through the plant cell wall by the T3SS may partially contribute to FLS2-dependent immunity, flagellin in the cytosol does not elicit immune-associated cell death. We postulate that a death response to translocated MAMPs would produce vulnerability to the many necrotrophic pathogens of plants, such as P.?carotovorum, which differ from P. syringae and other (hemi)biotrophic pathogens in benefitting from death-associated immune responses.

    Full Text Available Abstract Background The negative impact of overweight (including obesity and related treatment on children's and adolescents' health-related quality of life (HRQoL has been shown in few specific samples thus far. We examined HRQoL and emotional well-being in overweight children from an outpatient treatment sample as well as changes of these parameters during treatment. Methods In a cross-sectional design, self-reported HRQoL of 125 overweight (including obese children who contacted a treatment facility, but had not yet receive treatment, were compared to 172 children from randomly selected schools using independent two-sample t-tests. Additionally, in a longitudinal design, the overweight children were retested by administering the same questionnaire at the end of the intervention (after one year. It included measures such as the body mass index (BMI, the general health item (GHI, the KINDLR, and the Child Dynamic Health Assessment Scale (ChildDynHA. Comparisons were based on dependent t-tests and the Wilcoxon signed-rank test. Results Overweight children showed statistically significant impairment in the GHI (Cohen's d = 0.59 and emotional well-being (ChildDynha (d = 0.33 compared to the school children. With respect to HRQoL, the friends dimension of the KINDLR was significantly impaired in the overweight group (d = 0.33. However, no impairment was found for the total HRQoL score or other KINDLR subdimensions. Regarding the longitudinal part of our study, most of the children improved their BMI, but the majority (87.5% remained overweight. Nevertheless, the participants' perceived health, emotional well-being, and generic as well as disease-specific HRQoL improved during intervention. Conclusion The findings emphasize the importance of patient-reported outcomes such as HRQoL. Even though overweight and obesity might accompany most of the children throughout their lifetime, the impairment associated with this chronic condition can be considerably reduced. Opportunities of health promotion in overweight/obese children and adolescents are discussed.

    Full Text Available Abstract Background The emergence of Global Health Initiatives (GHIs has been a major feature of the aid environment of the last decade. This paper seeks to examine in depth the behaviour of two prominent GHIs in the early stages of their operation in Uganda as well as the responses of the government. Methods The study adopted a qualitative and case study approach to investigate the governance of aid transactions in Uganda. Data sources included documentary review, in-depth and semi-structured interviews and observation of meetings. Agency theory guided the conceptual framework of the study. Results The Ugandan government had a stated preference for donor funding to be channelled through the general or sectoral budgets. Despite this preference, two large GHIs opted to allocate resources and deliver activities through projects with a disease-specific approach. The mixed motives of contributor country governments, recipient country governments and GHI executives produced incentive regimes in conflict between different aid mechanisms. Conclusion Notwithstanding attempts to align and harmonize donor activities, the interests and motives of the various actors (GHIs and different parts of the government undermine such efforts.

    Resistance-Nodulation-Cell Division (RND) pumps play important roles in bacterial resistance to antibiotics. Pseudomonas aeruginosa is an important human pathogen which exhibits high level resistance to antibiotics. There are total of 12 RND pumps present in the P. aeruginosa PAOl genome. The recently characterized MuxABC-OpmB system has been shown to play a role in resistance to novobiocin, aztreonam, macrolides, and tetracycline in a multiple knockout mutation. In this study, we examined the expression levels of all the 12 RND pump gene clusters and tested the involvement of MuxABC-OpmB in pathogenicity. The results indicated that in addition to the four known constitutively expressed RND pumps, mexAB-oprM, mexGHI-opmD, mexVW, and mexXY, relatively high levels of expression were observed with mexJK and muxABC-opmB in the conditions tested. Inactivation of muxA in the muxABC-opmB operon resulted in elevated resistance to ampicillin and carbenicillin. The mutant also showed attenuated virulence in both Brassica rapa pekinensis and Drosophila melanogaster infection models. The decreased virulence at least in part was due to decreased twitching motility in the mutant. These results indicate that the RND pump MuxABC-OpmB is associated with ampicillin and carbenicillin susceptibility and also involved in pathogenesis in P. aeruginosa. PMID:21369987

    Yang, Hsi-Hsien; Tsai, Cheng-Hsien; Chao, Mu-Rong; Su, Yi-Ling; Chien, Shu-Mei

    Atmospheric particulate and polycyclic aromatic hydrocarbon (PAH) size distributions were measured at a suburban area in central Taiwan during the rice straw burning and non-burning periods. Samples were acquired using a semi-volatile sampling train (PS-1 sampler) and a micro-orifice uniform deposit impactor (MOUDI). The collected materials were extracted and then analyzed by gas chromatograph/mass selective detector for 21 PAHs. The average total PAH concentrations of particulate and gaseous phases were 33.0 and 1160 ng m -3, respectively, in the rice straw burning period, which were higher than those on the non-burning days. Potential sources of PAHs were identified using the characteristic ratios. Benzo[ a]pyrene/benzo[ ghi]perylene ratio indicates the burning of rice straw is a significant source for PAH contribution at the sampling area. It also suggests that the rice straw burning primarily contribute fine particulate PAHs. Bimodal size distributions are obtained with a predominance of total PAHs in the accumulation mode during rice straw burning periods and in ultra-fine mode during non-burning periods. The particulate and particulate phase PAHs from rice straw burning are coarser than those from vehicle exhaust. The results also suggest that the amounts of PAHs per unit mass of particulate are less for the burning of rice straw than those of vehicle emissions.

    To better assess the applicability of nitromethane as a selective quenching agent for alternant versus nonalternant polycyclic aromatic hydrocarbons in HPLC, TLC, and HPTLC analysis, the authors measured the effect that it has on the fluorescence emission behavior of 96 different polycyclic aromatic hydrocarbons dissolved in binary toluene/acetonitrile solvent mixtures. Results of these measurements revealed that the [open quotes]selective quenching[close quotes] rule is obeyed for the vast majority of PAHs, with the coronene derivatives being the only major exceptions. Fluorescence emission spectra are also reported for benzo[g]chrysene, naphtho[2,3g]chrysene, 4H-benzo[c]cyclo-penta[mno]chrysene, dibenzo[ghi,mno]fluoranthene (commonly called corannulene), rubicene, diacenaphtho[1,2j:1',2']fluoranthene, 10-methyl-benzo[b]fluoranthene, 3-methoxybenzo[k]fluoranthene, and 3-hydroxy-benzo[k]fluoranthene in organic nonelectrolyte solvents of varying polarity. Calculated emission intensity ratios failed to vary systematically with solvent polarity, and all nine of the aforementioned solutes were thus classified as nonprobe molecules. 63 refs., 4 figs., 2 tabs.

    2015-09-01

    Sun-tracking is one of the most challenging tasks in implementing CPV. In order to justify the additional complexity of sun-tracking, careful assessment of performance of CPV by monitoring the performance of sun-tracking is vital. Measurement of accuracy of sun-tracking is one of the important tasks in an outdoor test. This study examines techniques with three optoelectronic devices (i.e. position sensitive device (PSD), CCD and webcam). Outdoor measurements indicated that during sunny days (global horizontal insolation (GHI) > 700 W/m2), three devices recorded comparable tracking accuracy of 0.16˜0.3°. The method using a PSD has fastest sampling rate and is able to detect the sun's position without additional image processing. Yet, it cannot identify the sunlight effectively during low insolation. The techniques with a CCD and a webcam enhance the accuracy of centroid of sunlight via the optical lens and image processing. The image quality acquired using a webcam and a CCD is comparable but the webcam is more affordable than that of CCD because it can be assembled with consumer-graded products.

  7. Atmospheric deposition of polycyclic aromatic hydrocarbons to water surfaces: A mass balance approach

    Science.gov (United States)

    McVeety, Bruce D.; Hites, Ronald A.

    A mass balance model was developed to explain the movement of polycyclic aromatic hydrocarbons (PAH) into and out of Siskiwit Lake, which is located on a wilderness island in northern Lake Superior. Because of its location, the PAH found in this lake must have originated exclusively from atmospheric sources. Using gas Chromatographie mass spectrometry, 11 PAH were quantified in rain, snow, air, lake water, sediment core and sediment trap samples. From the dry deposition fluxes, an aerosol deposition velocity of 0.99 ± 0.15 cm s -1 was calculated for indeno[1,2,3- cd]pyrene and benzo[ ghi]perylene, two high molecular weight PAH which are not found in the gas phase. The dry aerosol deposition was found to dominate the wet removal mechanism by an average ratio of 9:1. The dry gas flux was negative, indicating that surface volatilization was taking place; it accounted for 10-80 % of the total output flux depending on the volatility of the PAH. The remaining PAH were lost to sedimentation. From the dry gas flux, an overall mass transfer coefficient for PAH was calculated to be 0.18 ± 0.06 m d -1. In this case, the overall mass transfer is dominated by the liquid phase resistance.

    The National Center for Atmospheric Research and partners are building a blended SunCast Solar Power Forecasting system. This system includes several short-range nowcasting models and improves upon longer range numerical weather prediction (NWP) models as part of the "Public-Private-Academic Partnership to Advance Solar Power Forecasting." The nowcasting models being built include statistical learning models that include cloud regime prediction, multiple sky imager-based advection models, satellite image-based advection models, and rapid update NWP models with cloud assimilation. The team has also integrated new modules into the Weather Research and Forecasting Model (WRF) to better predict clouds, aerosols, and irradiance. The modules include a new shallow convection scheme; upgraded physics parameterizations of clouds; new radiative transfer modules that specify GHI, DNI, and DIF prediction; better satellite assimilation methods; and new aerosol estimation methods. These new physical models are incorporated into WRF-Solar, which is then integrated with publically available NWP models via the Dynamic Integrated Forecast (DICast) system as well as the Nowcast Blender to provide seamless forecasts at partner utility and balancing authority commercial solar farms. The improvements will be described and results to date discussed.

    The electrical responses of a columnar liquid crystal (a diimidodiester derivative of benzo[ghi]perylene) deposited either by spin-coating or by thermal evaporation into a typical OLED device are compared. For the spin-coated film, homeotropic alignment was induced by thermal annealing, which enhanced the charge carrier mobility significantly. For the evaporated films, homeotropic alignment could not be obtained by annealing. However, a degree of rectification higher than 3 orders of magnitude was achieved, even without annealing, with an electrical response similar to the response of the aligned spin-coated film. A trap-limited space-charge-limited current model was used to extract the charge carrier mobility directly from the current-voltage curves. Grazing incidence wide-angle X-ray scattering confirmed the homeotropic alignment of the annealed spin-coated film, whereas the columns are mostly oriented parallel to the surface in the evaporated case. In a field-effect transistor with bottom-gate bottom-contact geometry, the evaporated film exhibited a typical behavior of an n-type transistor. The degree of intermolecular order is thereby strongly dependent on the deposition method where vacuum deposition leads to a higher order. This higher order, however, impedes reorientation by annealing of the evaporated film but leads to improved charge transport between the electrodes even without homeotropic alignment of columnar liquid crystal.

    Full Text Available [...] Abstract in english The electro-bioremediation is a technique that is used for the remediation of hydrocarbon contaminated soils. The aim of this study is to explore the electro-bioremediation of an unsaturated soil, contaminated with hydrocarbon waste generated by the oil industry activity in the area and previously r [...] emediated by landfarming, to in order to increase the removal of polyaromatic hydrocarbons. The sample was put in a three-compartment electro-bioremediation glass cell of 58 cm long, the lateral compartments containing the electrolyte; we used bridges of ammonium phosphate to connect the electrolyte with the soil sample in the central compartment. A potential difference of 0.5 V cm-1 was applied to the electro-bioremediation cells for 60 days. A second cell was used for control and no current was applied to it. The monitoring was carried out by a counting cell and measuring of n-alkanes and polyaromatic hydrocarbons using GC mass. The results showed that this technology has good potential to increase the biodegradation of n-alkane hydrocarbons and polyaromatic hydrocarbons such as phenanthrene, 1-3-metilphenanthrene, chrysene, 3-methylchrysene, 6-methylchrysene, benzo(b)fluoranthrene and benzo(ghi)pyrene which, without the application of direct current, were not biodegraded by microorganisms in the soil. The use of salt bridges maintained the pH between values that are compatible with the degrading bacterial community.

    In Bacillus subtilis, the extracytoplasmic function (ECF) ? factors ?(M) , ?(W) and ?(X) all contribute to resistance against lantibiotics. Nisin, a model lantibiotic, has a dual mode of action: it inhibits cell wall synthesis by binding lipid II, and this complex also forms pores in the cytoplasmic membrane. These activities can be separated in a nisin hinge-region variant (N20P M21P) that binds lipid II, but no longer permeabilizes membranes. The major contribution of ?(M) to nisin resistance is expression of ltaSa, encoding a stress-activated lipoteichoic acid synthase, and ?(X) functions primarily by activation of the dlt operon controlling d-alanylation of teichoic acids. Together, ?(M) and ?(X) regulate cell envelope structure to decrease access of nisin to its lipid II target. In contrast, ?(W) is principally involved in protection against membrane permeabilization as it provides little protection against the nisin hinge region variant. ?(W) contributes to nisin resistance by regulation of a signal peptide peptidase (SppA), phage shock proteins (PspA and YvlC, a PspC homologue) and tellurite resistance related proteins (YceGHI). These defensive mechanisms are also effective against other lantibiotics such as mersacidin, gallidermin and subtilin and comprise an important subset of the intrinsic antibiotic resistome of B.?subtilis.

    Mycobacterium tuberculosis is able to synthesize molybdopterin cofactor (MoCo), which is utilized by numerous enzymes that catalyze redox reactions in carbon, nitrogen, and sulfur metabolism. In bacteria, MoCo is further modified through the activity of a guanylyltransferase, MobA, which converts MoCo to bis-molybdopterin guanine dinucleotide (bis-MGD), a form of the cofactor that is required by the dimethylsulfoxide (DMSO) reductase family of enzymes, which includes the nitrate reductase NarGHI. In this study, the functionality of the mobA homolog in M. tuberculosis was confirmed by demonstrating the loss of assimilatory and respiratory nitrate reductase activity in a mobA deletion mutant. This mutant displayed no survival defects in human monocytes or mouse lungs but failed to persist in the lungs of guinea pigs. These results implicate one or more bis-MGD-dependent enzymes in the persistence of M. tuberculosis in guinea pig lungs and underscore the applicability of this animal model for assessing the role of molybdoenzymes in this pathogen.

    Objectives By using the Global Fund as a case example, we aim to critically evaluate the evidence generated from 2002 to 2009 for potential negative health system effects of Global Health Initiatives (GHI). Design Systematic review of research literature. Setting Developing Countries. Participants All interventions potentially affecting health systems that were funded by the Global Fund. Main outcome measures Negative health system effects of Global Fund investments as reported by study authors. Results We identified 24 studies commenting on adverse effects on health systems arising from Global Fund investments. Sixteen were quantitative studies, six were qualitative and two used both quantitative and qualitative methods, but none explicitly stated that the studies were originally designed to capture or to assess health system effects (positive or negative). Only seemingly anecdotal evidence or authors’ perceptions/interpretations of circumstances could be extracted from the included studies. Conclusions This study shows that much of the currently available evidence generated between 2002 and 2009 on GHIs potential negative health system effects is not of the quality expected or needed to best serve the academic or broader community. The majority of the reviewed research did not fulfil the requirements of rigorous scientific evidence. PMID:23162683

    A new 10-km hourly solar resource product was created for India. This product was created using satellite radiances from the Meteosat series of satellites. The product contains global horizontal irradiances (GHI) and direct normal irradiances (DNI) for the period from 2002 to 2011. An additional solar resource data set covering the period from January 2012 to June 2012 was created solely for validation because this period overlaps ground measurements that were made available from the Indian Ministry of New and Renewable Energy's (MNRE's) National Institute for Solar Energy for five stations that are part of MNRE's solar resource network. These measurements were quality checked using the SERI QC software and used to validate the satellite product. A comparison of the satellite product to the ground measurements for the five stations shows good agreement. This report also presents a comparison of the new version of solar resource data to the previous version, which covered the period from 2002 to 2008.

    Polycyclic aromatic hydrocarbons (PAHs) are pollutants found in living and working environments. The aim of this study was to develop a solid-phase microextraction (SPME) gas chromatography (GC)-isotope dilution mass spectrometry method for the quantification of 10 four- to six-ring PAHs in urine samples. Seven of the selected PAHs have been classified as carcinogenic. Under the final conditions, analytes were sampled with a 100-?m polydimethylsiloxane SPME fibre for 60 min at 80 °C and desorbed in the injection port of the GC at 270 °C. Fluoranthene, pyrene, benz[a]anthracene, chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[a]pyrene, dibenzo[a,h]anthracene, indeno[1,2,3-cd]pyrene and benzo[ghi]perylene were separated using a highly arylene-modified phase capillary column and quantified by MS using eight deuterated PAHs as surrogate internal standards. Limits of quantification (LOQ) were in the 0.5- to 2.2-ng/L range. Validation showed linear dynamic ranges up to 340 ng/L, inter- and intra-run precisions coke oven workers (n?=?12), asphalt workers (n?=?10) and individuals not occupationally exposed to PAHs (n?=?18), respectively. Chrysene was the most abundant PAH determined with median levels of 62.6, 6.9 and <0.6 ng/L, respectively. These results show that the method is suitable for quantifying carcinogenic PAHs in specimens from individuals with different levels of PAH exposure. PMID:21626187

    A benzoperylene probe excimer emission in an aqueous buffer solution is observed for the first time, and a novel ratiometric fluorescence method based on the probe excimer emission for the sensitive detection of heparin and heparinase is demonstrated. A negatively charged benzoperylene derivative, 6-(benzo[ghi]perylene-1,2-dicarboxylic imide-yl)hexanoic acid (BPDI), was employed. A polycation, poly(diallyldimethylammonium) chloride (poly-DDA), could induce aggregation of BPDI through noncovalent interactions. A decrease of BPDI monomer emission and a simultaneous increase of BPDI excimer emission were observed. Upon the addition of heparin, the strong binding between heparin and poly-DDA caused release of BPDI monomer molecules, and an excimer-monomer emission signal transition was detected. However, after the enzymatic hydrolysis of heparin by heparinase, heparin was hydrolyzed into small fragments, which weakened the competitive binding of heparin to poly-DDA. Poly-DDA induced aggregation of BPDI, and a monomer-excimer emission signal transition was detected. Our assay is simple, rapid, inexpensive, sensitive and selective, which could facilitate the heparin and heparinase related biochemical and biomedical research. PMID:26344903

    The concentrations of eight polycyclic aromatic hydrocarbons (PAH), anthracene, pyrene, chrysene, benzo(k)fluoranthene, benzo(a)pyrene, benzo(ghi)perylene, fluoranthene, and perylene, were measured in clams, Tridacna maxima, collected from sites on the Great Barrier Reef ranging in latitude from 14/sup 0/31'S to 23/sup 0/33' S. At most locations the concentrations of PAH were not significantly above the limit of detection, e.g., pyrene < 0.07 ..mu..g/kg wet weight, benzo(a)pyrene < 0.01 ..mu..g/kg, and chrysene < 0.07 ..mu..g/kg. These levels of PAH appear to be the lowest reported for clams anywhere in the world, indicating the pristine nature of the Great Barrier Reef at the present time. Concentrations significantly above detection levels were found at only two sites, Lizard Island First Beach (anthracene, 3.2 ..mu..g/kg; pyrene, 1.4 ..mu..g/kg) and Heron Island Harbour (pyrene, 1.2 ..mu..g/kg; benzo(a)pyrene, 0.02 ..mu..g/kg). Both sites are frequently visited by power boats which are the most likely source of hydrocarbon contamination. These low levels of contamination would not have been demonstrated by the measurement of only the most commonly studied PAH, benzo(a)pyrene. Simultaneous determination of several PAH was necessary to show clearly that some localized pollution had occurred.

  18. Comparative in vitro effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin and selected polynuclear aromatic hydrocarbons on cyp1a1 gene transcription in cells which contain or are deficient in the 4S binding protein

    International Nuclear Information System (INIS)

    Using [3H]-benzo[a]pyrene as the radioligand, several cell culture lines have been screened for the presence (or absence) of the 4S binding protein. Murine Hepa 1c1c7 cells contained both the 4S binding protein and the 9S (Ah) receptor whereas only the 9S receptor was detected in rat hepatoma H-4-II E cells in culture. The effects of a series of polynuclear aromatic hydrocarbons (PAHs) which included benzo[e]pyrene, benzo[ghi]perylene and 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and their interactive effects on CYP1A1 gene transcription was determined by Northern analysis in both cell lines. The results showed that the PAHs which exhibited high affinity for the 4S binding protein were inactive as inducers in both cell lines; TCDD was active in both cell lines and the interactive effects between the PAHs and TCDD did not significantly modulate TCDD-mediated CYP1A1 gene transcription. The results suggest that the 4S binding protein does not regulate CYP1A1 gene transcription

  19. Polypyrrole Composite Film for Highly Sensitive and Selective Electrochemical Determination Sensors

    International Nuclear Information System (INIS)

    In this paper, polypyrrole (PPy) and benz[a]anthracene-7,12-dione (BaD) were electro-polymerized onto a pyrolytic graphite electrode (PGE), constructing a novel BaD/PPy/PGE platform for electrochemical sensoring. The morphology and electrochemical properties of the fabricated BaD/PPy/PGE were characterized by scanning electron microscopy, cyclic voltammetry and electrochemical impedance spectroscopy. Furthermore, the electrochemical behavior of benzo[k]fluoranthene (BkF) at the BaD/PPy/PGE was investigated. Due to the specific interactions between BkF and BaD, a wide linear range of BkF detection from 1.0 × 10?12 to 1.0 × 10?9 M with good linearity (R2 = 0.9962) and a low detection limit (1.0 × 10?13 M, S/N = 3) were demonstrated. Importantly, other similar aromatics which had one ring or more than two rings, such as benzo[a]anthracene, benzo[a]pyrene, pyrene, benzo[ghi]peryle, anthracene, phenanthrene, naphthalene and parachlorophenol, showed insignificant interference on BkF detection. Consequently, this novel BaD/PPy/PGE with excellent stability and selectivity holds promise as an effective BkF electrochemical sensor in aqueous solution. As an example for its practical application, the newly developed sensor was applied to quantitative determination of BkF in waste water samples obtained from a coking plant with satisfactory sensitivity, selectivity, and reversibility

    Full Text Available Extra-terrestrially, there is no stochasticity in the solar irradiance, hence deterministic models are often used to model this data. At ground level, the Box-Jenkins Seasonal/Non-seasonal Autoregressive Integrated Moving Average (S/ARIMA) short memory stochastic models have been used to model such [...] data with some degree of success. This success is attributable to its ability to capture the stochastic component of the irradiance series due to the effects of the ever-changing atmospheric conditions. However, irradiance data recorded at the earth's surface is rarely entirely stochastic but a mixture of both deterministic and stochastic components. One plausible modelling procedure is to couple sinusoidal predictors at determined harmonic (Fourier) frequencies to capture the inherent periodicities (seasonalities) due to the diurnal cycle, with SARI-MA models capturing the stochastic components. We construct such models which we term, harmonically coupled SARIMA (HCSARIMA) models and use them to empirically model the global horizontal irradiance (GHI) recorded at the earth's surface. Comparison of the two classes of models shows that HCSARIMA models generally out-compete SARI-MA models in the forecasting arena.

    Full Text Available A new resource for sun strength data in Southern Africa has been established with the commissioning of a regional network of solar monitoring stations. The Southern African Universities Radiometric Network (SAURAN) is an initiative of Stellenbosch University and the University of KwaZulu-Natal (UKZN [...] ), and consists of an initial set of ten ground stations equipped with secondary standard thermopile radiometers. SAURAN's aim is to provide a long-term record of sun strength in a region that shows excellent potential for the deployment of solar energy technologies. Instruments measuring direct normal irradiance (DNI), diffuse horizontal irradiance (DHI) and global horizontal irradiance (GHI) feed time-averaged data over 1-minute, hourly and daily intervals to a central archive from where they are accessible to the public via a website interface. Meteorological data is also provided by most of the stations. This paper gives a brief background to the SAURAN project and describes the network's operation, coverage and future expansion. Examples of solar energy irradiance plots are also provided to illustrate the information available from the SAURAN database.

  4. Exploration and development of the climate archive of the Allan Hills Blue Ice Area, Antarctica

    Spaulding, Nicole E.

    The ice flow, stable water isotopic composition, and glaciochemistry of ice within the Allan Hills Blue Ice Area (AH BIA), Antarctica, is investigated to determine its potential for contributing to and extending the currently available 800 ka ice core record of paleoclimate. The investigation began with a study of ice dynamics within the AH BIA. The horizontal (u ) and vertical (z) ice velocities, determined using high-precision GPS measurements, are 1.5 to 50 (+0.12) cm a--1 and 2-3 (+/-0.50) cm a--1, respectively. The significant positive z and low u verify that old ice is present at the surface. Surface topography, in combination with u, was used to delineate a flowline (A-B) along which ice of continuous age was collected for the next stage of the investigation. Surface ice was recovered along 5 km of A-B and a 225 meter core was drilled at its midpoint. Ice samples were analyzed for stable isotopes of water (deltaD, delta 18O), which are common proxies for temperature. The resulting profiles exhibit variability consistent with the magnitude of glacial-interglacial transitions in East Antarctica. These variations, in combination with 40Aratm, and delta18O atm constrain the age of sampled ice to 90-250 ka. However, the 100 meters of directly above bedrock was not collected and the bottom depth is calculated to be at least 400 ka. The final phase of the investigation involved determining the concentrations of terrestrial and marine chemical species in ice from multiple points along A-B. Concentrations ranged from pg L--1 level for rare earth elements to microg L --1 level for multi-sourced compounds like sulfate. The concentrations of all analytes were anti-correlated with stable water isotope values indicating they had preserved a record of changes in atmospheric circulation, source strength, and continental aridity. The composition of rare earth elements points to Australia as an important interglacial dust source, while molar ratios of major ions, particularly Ca2+:C1-- and Mg2+:C1--, suggest that transport pathways through the McMurdo Dry Valleys cannot be disregarded. In summary, the data collected suggest that ice within the AH BIA is stratigraphically conformable, is older than that recovered in surrounding regions and does contain a well-preserved environmental record.

  5. Declines in populations of Salix caprea L.during forest regeneration after strong herbivore pressure

    Full Text Available Communities of broadleaved forest subject to strong pressure from large herbivores underwent degeneration. The relief of this pressure led to regeneration of the community, in which an important role was played by the sallow Salix caprea and other light-seeded pioneer species of tree (Populus tremula, Betula pendula and B. pubescens. Regeneration involving Salix caprea proceeded following the conservatorial protection of the degenerate stands in a reserve and later in Bia?owie?a National Park. The emergence and development of the population of Salix caprea proceeded following the invasion of spruce, which coincided with the period of enhanced animal pressure on broadleaved forest. Salix caprea filled all the gaps in the tree stand arising as a result of the destruction of trees and undergrowth by herbivores (in the years 1892-1915. It also appeared en masse on old, at that time unforested, clearings and felled areas. In these places, Salix caprea created very abundant populations, with particular trees being in good condition, with a habit typical of forest trees and attaining considerable heights. The majority of trees were 50-60 years old at the time of death, although individuals reached 74 years of age. The process of extinction of the sallow population - observed over 19 years on permanent plots and fixed trees - proceeded very quickly, especially in the first decade of observation. It led to the almost complete disappearance of sallow for the forest communities of Bia?owie?a National Park. The death of individual trees is preceded by impairment of their health and reduced annual increments in the 4-9 last years of life. The extinction of the population is associated with the loss of its primary phenological differentiation and with a change in the sex structure of the population from a prevalence of female trees to a near even distribution of the two sexes. The development of the populations of permanent constituents of the forest (Carpinus betulus, Tilia cordata, Acer platanoides and Ulmus glabra under the canopy of light-seeded trees, and the non-creation of a new generation of pioneer species points to the imminent end of the process of regeneration in the forest communities of Bia?owie?a National Park.

Research has been carried out by consulting the original archives of the Polish administration, press of the Polish Socialist Party and accounts of key witnesses. These sources clearly show that, when Polesie was integrated into Poland after the First World War, in 1920, many inhabitants of the region (the so-called "Poleszucy" and "tutejsi" did not consider themselves Belarusian in the national sense. These "nationality unconscious" people progressively came to consider themselves as members of a Soviet Belarusian nation as a result of the struggle between Polish, Belarusian and Ukrainian political organizations. This research highlights the fact that national identity is neither determined by ethnic affiliations nor can be ascribed to an ethnic group against its will.Próby wykszta?cenia to?samo?ci narodowej u ludno?ci s?owia?skiej na Polesiu w pierwszych latach II Rzeczypospolitej Polskiej (1920-1928Artyku? opisuje ewolucj? to?samo?ci narodowej s?owia?skiej ludno?ci zamieszkuj?cej Polesie w pierwszym dziesi?cioleciu II Rzeczypospolitej.

    Full Text Available Abstract Background Cachexia is a common problem in patients (pts suffering from upper gastrointestinal cancer. In addition, most of these patients suffer from malabsorption and stenosis of the gastrointestinal tract due to their illness. Various methods of supplementary nutrition (enteral, parenteral are practised. In patients with advanced pancreatic cancer (APC, phase angle, determined by bio-electrical impedance analysis (BIA, seems to be a survival predictor. The positive influence of BIA determinate predictors by additional nutrition is currently under discussion. Methods To examine the impact of additional parenteral nutrition (APN we assessed outpatients suffering from APC and progressive cachexia. The assessment based on the BIA method. Assessment parameters were phase angle, ECM/BCM index (ratio of extracellular mass to body cell mass, and BMI (body mass index. Patients suffering from progressive weight loss in spite of additional enteral nutritional support were eligible for the study. Results Median treatment duration in 32 pts was 18 [8-35] weeks. Response evaluation showed a benefit in 27 pts (84% in at least one parameter. 14 pts (43.7% improved or stabilised in all three parameters. The median ECM/BCM index was 1.7 [1.11-3.14] at start of APN and improved down to 1.5 [1.12-3.36] during therapy. The median BMI increased from 19.7 [14.4-25.9] to 20.5 [15.4-25.0]. The median phase angle improved by 10% from 3.6 [2.3-5.1] to 3.9 [2.2-5.1]. Conclusions We demonstrated the positive impact of APN on the assessed parameters, first of all the phase angle, and we observed at least a temporary benefit or stabilisation of the nutritional status in the majority of the investigated patients. Based on these findings we are currently investigating the impact of APN on survival in a larger patient cohort. Trial registration ClinicalTrials.gov Identifier: NCT00919659

    2012-01-01

    The formation of planetesimals is often accredited to collisional sticking of dust grains. The exact process is unknown, as collisions between larger aggregates tend to lead to fragmentation or bouncing rather than sticking. Recent laboratory experiments have however made great progress in the understanding and mapping of the complex physics involved in dust collisions. We want to study the possibility of planetesimal formation using the results from the latest laboratory experiments, particularly by including the fragmentation with mass transfer effect, which might lead to growth even at high impact velocities. We present a new experimentally and physically motivated dust collision model capable of predicting the outcome of a collision between two particles of arbitrary masses and velocities. It is used together with a continuum dust-size evolution code that is both fast in terms of execution time and able to resolve the dust well at all sizes, allowing for all types of interactions to be studied without bia...

    Toxoplasma gondii Nicolle et Manceaux, 1908 is an apicomplexan parasite with a worldwide distribution. It is of great medical and veterinary importance because it may cause abortion or congenital disease in its intermediate hosts, including man. The European bison, the largest herbivorous animal in Europe, is a species that has been saved from extinction. Twenty-four of 95 examined sera of the European bison (Bison bonasus bonasus) from the Bia?owieza Forest, Poland collected from 2008 to 2011 were found to be positive for the presence of T. gondii-specific IgG antibodies using a direct agglutination test, with the antibody titre in positive animals ranging from 40 to 18000. Statistically significant differences were observed only between years of sample collection. This is the first report on T. gondii in lowland European bison living in the natural environment.

    Current and future imaging surveys will measure cosmic shear with statistical precision that demands a deeper understanding of potential systematic biases in galaxy shape measurements than has been achieved to date. We use analytic and computational techniques to study the impact on shape measurements of two atmospheric chromatic effects for ground-based surveys such as the Dark Energy Survey (DES) and the Large Synoptic Survey Telescope (LSST): (i) atmospheric differential chromatic refraction (DCR) and (ii) wavelength dependence of seeing. We investigate the effects of using the point spread function (PSF) measured with stars to determine the shape of a galaxy that has a different spectral energy distribution (SED) than the stars. For (i), we extend a study by Plazas & Bernstein based on analytic calculations that show that DCR leads to significant biases in galaxy shape measurements for future surveys, if not corrected. For (ii), we find that the wavelength dependence of seeing leads to significant bia...

    Full Text Available Large amounts of waste materials are discarded in the sugarcane industry. This work investigates the reuse of sugarcane bagasse ash waste as an alternative raw material for porcelain stoneware tile bodies, replacing natural quartz by up to 5 wt.%. The tile pieces were fired at 1230 °C using a fast-firing cycle (< 60 min. The technological properties of the fired tile pieces (e.g., linear shrinkage, water absorption, apparent density, and flexural strength were determined. The sintering process was followed by SEM and XRD analyses. The results show that up to 2.5 wt.% sugarcane bagasse ash waste can be used as a partial replacement for quartz in porcelain stoneware tile (group BIa, ISO 13006 standard, providing excellent technical properties. Hence, its application in high-quality ceramic tile for use in civil construction as a low-cost, alternative raw material could be an ideal means of managing sugarcane bagasse ash waste.

    Malnutrition is highly prevalent in peritoneal dialysis (PD) patients and is associated with higher mortality. Lower serum levels of markers of nutrition--such as albumin, creatinine, prealbumin, and total cholesterol--are important risk factors in PD patients. Usefulness of bioimpedance analysis (BIA) in hemodialysis (HD) patients has been reported. In the present study, we prospectively examined the relationship of bioimpedance indexes to the nutrition status and survival of 45 PD patients who were followed for more than 1 year. On patient enrollment, a BIA was performed (Bioelectrical Impedance Analyzer, Model BIA-101: RJL Systems, Clinton Township, MI, U.S.A.). Monthly blood was analyzed for biochemical markers. The mean age of the study group was 50 +/- 15 years. Of the 45 patients, 56% were female and 24% were diabetic. Mean body mass index was 25.7 +/- 5.1. Mean resistance, reactance, capacitance, and phase angle were 524 +/- 106 omega 57 +/- 20 omega, 678 +/- 223 pF, and 6.2 +/- 1.7 degrees respectively. Patients with diabetes had lower capacitance (555 pF vs. 713 pF, p = 0.007) and phase angle (5.35 degrees vs. 6.4 degrees, p = 0.05) than patients without diabetes. During the study period, 4 patients died. Patients who survived had higher capacitance (486 +/- 163 pF vs. 697 +/- 218 pF, p = 0.07) and phase angle (4.65 +/- 0.73 degrees, vs. 6.34 +/- 1.67 degrees, p = 0.008) than those who did not survive. The Kaplan-Meier method was used to compute observed survival. The cumulative observed survival of PD patients with an enrollment phase angle > or = 6 degrees was significantly (p = 0.01) higher than that of patients with an enrollment phase angle < 6 degrees. Reactance was directly correlated with albumin (r = 0.52, p < 0.0001) and total protein (r = 0.44, p < 0.05). Capacitance was directly correlated with body mass index (r = 0.35, p < 0.05), albumin (r = 0.32, p < 0.05), and blood urea nitrogen (BUN) (r = 0.44, p < 0.01), and inversely correlated with body weight (r = -0.51, p < 0.0001). Phase angle was directly correlated with all of the biochemical markers of nutrition, such as albumin (r = 0.54, p < 0.01), total protein (r = 0.38, p < 0.05), creatinine (r = 0.28, p < 0.01), and BUN (r = 0.39, p < 0.05). By stepwise multivariate regression analysis, body weight (beta = -0.60, p < 0.0001) and total protein (beta = 0.32, p = 0.012) were significant determinants of resistance. Body weight (beta = -0.31, p = 0.02) and albumin (beta = 0.59, p < 0.0001) were significant predictors of reactance. Serum albumin (beta = 0.53, p < 0.0001) was the only best predictor of phase angle in PD patients. The BIA indices reflect nutrition status in PD patients, and may be useful in monitoring nutrition interventions. PMID:12402618

    Strain engineering has proven to be vital for germanium-based photonics, in particular light emission. However, applying a large permanent biaxial strain to germanium has been a challenge. We present a simple, CMOS-compatible technique to conveniently induce a large, spatially homogenous strain in microdisks patterned within ultrathin germanium nanomembranes. Our technique works by concentrating and amplifying a pre-existing small strain into the microdisk region. Biaxial strains as large as 1.11% are observed by Raman spectroscopy and are further confirmed by photoluminescence measurements, which show enhanced and redshifted light emission from the strained microdisks. Our technique allows the amount of biaxial strain to be customized lithographically, allowing the bandgaps of different microdisks to be independently tuned in a single mask process. Our theoretical calculations show that this platform can deliver substantial performance improvements, including a >200x reduction in the lasing threshold, to bia...

    A procedure based on BIA Separations CIM DEAE anion-exchange chromatography was developed to separate double-stranded (ds) RNA of hypovirus infecting phytopathogenic fungus Cryphonectria parasitica. Using a linear gradient of 25 mM 4-morpholinepropanesulfonic acid (MOPS), pH 7.0 as a binding buffer, and 25 mM MOPS, 1.5 M NaCl, 0.1 mM EDTA, 15% isopropanol (v/v), pH 7.0 as an elution buffer, hypoviral dsRNA was additionally purified from nucleic acid species present in preparations partially purified by standard CF-11 cellulose chromatography. Moreover, crude phenol/chloroform extracts of the fungal tissue were also applied to monolithic supports and CIM DEAE chromatograms revealed clear evidence for hypoviral presence without CF-11 chromatography, nucleic acid precipitation, and electrophoresis.

    Elevated degree of body fatness and changes in other body composition parameters are known to be common effects of treatment for acute lymphoblastic leukemia (ALL) in children. In order to study peculiarities of somatic growth and development in ALL survivors, we describe the results of BIA body composition analysis of 112 boys and 108 girls aged 5-18 years in remission from ALL (remission time range 1-13 years) compared to data from the same number of age- and sex-matched healthy controls (n=220). Detrimental effect on height in ALL boys was observed, whereas girls experienced additional weight gain compared to healthy subjects. In ALL patients, resistance, body fat, and percent body fat were significantly increased. The reactance, phase angle, absolute and relative values of skeletal muscle and body cell mass were significantly decreased. Principal component analysis revealed an early prevalence of adiposity traits in the somatic growth and development of ALL girls compared to healthy controls.

    The Osage Mineral Reservation Estate is located in Osage County, Oklahoma. Minerals on the Estate are owned by members of the Osage Tribe who are shareholders in the Estate. The Estate is administered by the Osage Agency, Branch of Minerals, operated by the U.S. Bureau of Indian Affairs (BIA). Oil, natural gas, casinghead gas, and other minerals (sand, gravel, limestone, and dolomite) are exploited by lessors. Operators may obtain from the Branch of Minerals and the Osage Mineral Estate Tribal Council leases to explore and exploit oil, gas, oil and gas, and other minerals on the Estate. Operators pay a royalty on all minerals exploited and sold from the Estate. A mineral Resource Information system was developed for this project to evaluate the remaining hydrocarbon resources located on the Estate. Databases on Microsoft Excel spreadsheets of operators, leases, and production were designed for use in conjunction with an evaluation spreadsheet for estimating the remaining hydrocarbons on the Estate.

    This review is focused on experimental methods for determination of the composition of the human body, its organs and tissues. It summarizes the development and current status of fat determinations from body density, total body water determinations through the dilution technique, whole and partial body potassium measurements for body cell mass estimates, in vivo neutron activation analysis for body protein measurements, dual-energy absorptiometry (DEXA), computed tomography (CT) and magnetic resonance imaging (MRI, fMRI) and spectroscopy (MRS) for body composition studies on tissue and organ levels, as well as single- and multiple-frequency bioimpedance (BIA) and anthropometry as simple easily available methods. Methods for trace element analysis in vivo are also described. Using this wide range of measurement methods, together with gradually improved body composition models, it is now possible to quantify a number of body components and follow their changes in health and disease.

    Sarcopenia is a term that was introduced to describe 'low muscle mass'. There is no consensus definition for sarcopenia; a variety of criteria are being used to establish the diagnosis of 'sarcopenia'. Depending on the criteria used, the prevalence of sarcopenia in elderly varies from 7% to over 50%. The presence of sarcopenia often remains unrecognized when the loss of muscle mass is replaced by fat and connective tissue; body weight thus remains stable or even increases. Sarcopenia can be detected by measuring muscle mass with dual-energy X-ray absorptiometry (DEXA) or bioimpedance analysis (BIA). Besides the generation of strength, muscle tissue is an important internal organ involved in protein storage, glucose regulation, hormonal homeostasis and cellular communication. Systemic, cellular, neuromechanical factors and lifestyle are linked to the pathophysiology of sarcopenia. Sarcopenia is associated with higher mortality, dependency in activities of daily living, toxicity of chemotherapy, and disturbed glucose regulation. PMID:26230341

    Liver transplantation (LT) is a major surgery performed on patients with end stage liver disease. Nutrition is an integral part of patient care, and protein-energy malnutrition is almost universally present in patients suffering from liver disease undergoing LT. Nutrition assessment of preliver transplant phase helps to make a good nutrition care plan for the patients. Nutrition status has been associated with various factors which are related to the success of liver transplant such as morbidity, mortality, and length of hospital stay. To assess the nutritional status of preliver transplant patients, combinations of nutrition assessment methods should be used like subjective global assessment, Anthropometry mid arm-muscle circumference, Bioelectrical impedance analysis (BIA) and handgrip strength.

    Full Text Available In this paper we present new results of spectra-photometrical investigations of the flaring kernels' sizes and their intensities measured simultaneously in various parts of the H? line profile. Our investigations were based on the very high temporal resolution spectral-imaging observations of the solar flares collected with Large Coronagraph (LC, Multi-channel Subtractive Double Pass Spectrograph and Solar Eclipse Coronal Imaging System (MSDP-SECIS at Bia?kow Observatory (University of Wroc?aw, Poland.

    We have found that the areas of the investigated individual flaring kernels vary in time and in wavelengths, as well as the intensities and areas of the H? flaring kernels decreased systematically when observed in consecutive wavelengths toward the wings of the H? line. Our result could be explained as an effect of the cone-shaped lower parts of the magnetic loops channeling high energy particle beams exciting chromospheric plasma.

  7. Enhanced network reconstruction from irreducible local information

    2013-01-01

    Network topology plays a key role in many phenomena, from the spreading of diseases to that of financial crises. Whenever the whole structure of a network is unknown, one must resort to reconstruction methods that identify the least biased ensemble of networks consistent with the partial information available. A challenging case is when there is only local (node-specific) information available. For binary networks, the relevant ensemble is one where the degree (number of links) of each node is constrained to its observed value. However, for weighted networks the problem is much more complicated. While the naive approach prescribes to constrain the strengths (total link weights) of all nodes, recent counter-intuitive results suggest that in weighted networks the degrees are often more informative than the strengths, and as `fundamental' as the latter. This implies that the reconstruction of weighted networks would be significantly enhanced by the specification of both quantities, a computationally hard and bia...

    Information on species of parasitic helminths native to Poland is provided by the Pasozytnicze helminty Polski. Gatunki. Zywiciele. Bia?e Plamy. Until the middle of 2007, there were 1205 species of recorded helminths including 126 species of Monogenea, 338 of Trematoda (Digenea), 279 of Cestoda, 427 of Nematoda and 35 of Acanthocephala. They represented 32.9% of the species recorded in Europe (i.e., registered in the Fauna Europaea database). During the following three years up to the middle of 2010, 64 new species of Polish helminths were detected: 7 Monogenea, 15 Trematoda (Digenea), 21 Cestoda, 20 Nematoda and one Acanthocephala. Most hosts of the new helminth species were reported from birds (40 species), but also from fish (13 species) and mammals (10 species). Only one new species of helminth was detected in amphibians.

    Bonneville Power Administration (BPA) proposes to fund that portion of the Washington Wildlife Mitigation Agreement pertaining to the Lower Yakima Valley Wetlands and Riparian Restoration Project (Project) in a cooperative effort with the Yakama Indian Nation and the Bureau of Indian Affairs (BIA). The proposed action would allow the sponsors to secure property and conduct wildlife management activities for the Project within the boundaries of the Yakama Indian Reservation. This Environmental Assessment examines the potential environmental effects of acquiring and managing property for wildlife and wildlife habitat within a large 20, 340 hectare (50, 308 acre) project area. As individual properties are secured for the Project, three site-specific activities (habitat enhancement, operation and maintenance, and monitoring and evaluation) may be subject to further site-specific environmental review. All required Federal/Tribal coordination, permits and/or approvals would be obtained prior to ground disturbing activities.

    Full Text Available La bronquitis infecciosa aviar (BIA) es una enfermedad viral ampliamente diseminada en el mundo y se considera una de las principales causas de pérdidas económicas significativas en la industria avícola, debido a que afecta el desarrollo de aves de engorde y ponedoras. En Cuba, el diagnóstico actual [...] se realiza por aislamiento viral y es difícil su identificación por métodos convencionales. Para identificar la posible presencia del virus de la BIA en aislados cubanos se aplicó un ensayo de reverso transcripción acoplado a reacción en cadena de la polimerasa (RT-PCR) específico para este virus. Las muestras de tráquea-pulmón fueron tomadas como grupos de tres y cuatro aves después de la necropsia de cada una, evaluándose un total de once aves. Las secuencias del virus de la BIA fueron detectadas en dos de los tres grupos evaluados. En uno de estos grupos se logró además, la detección del virus a partir de la muestra clínica; aspecto importante para la diferenciación con enfermedades graves que cursan con un cuadro clínico similar como la Influenza aviar y la Enfermedad de Newcastle. La RT-PCR mostró potencial para ser usado en la identificación de aislados del virus de la BIA, así como en el examen directo a partir de muestras clínicas, lo que aporta posibilidades de su empleo en nuestro país para la detección rápida, sensible y específica de este agente, aspecto esencial en el diagnóstico y control de esta infección viral. Abstract in english Avian infectious bronchitis (AIB) is a viral disease worldwide distributed and it is considered one of the main causes of economic losses for poultry industry because of its characteristic of affecting development of broiler and laying hens.

    This work reports the investigation and analysis of bovine milk quality by using biological impedance measurements using electrical impedance spectroscopy (EIS). The samples were distinguished by a first chemical analysis using Fourier transform midinfrared spectroscopy (FTIR) and flow citometry. A set of milk samples (100ml each) obtained from 17 different cows in lactation with and without mastitis were analyzed with the proposed technique using EIS. The samples were adulterated by adding distilled water and hydrogen peroxide in a controlled manner. FTIR spectroscopy and flow cytometry were performed, and impedance measurements were made in a frequency range from 500Hz up to 1MHz with an implemented EIS system. The system's phase shift was compensated by measuring saline solutions. It was possible to show that the results obtained with the Bioelectrical Impedance Analysis (BIA) technique may detect changes in the milk caused by mastitis and the presence of water and hydrogen peroxide in the bovine milk.

    2015-12-01

    We introduce the balanced ideological antipathy (BIA) model, which challenges assumptions that right-wing authoritarianism (RWA) and social dominance orientation (SDO) predict inter-group antipathy per se. Rather, the effects of RWA and SDO on antipathy should depend on the target's political orientation and political objectives, the specific components of RWA, and the type of antipathy expressed. Consistent with the model, two studies (N = 585) showed that the Traditionalism component of RWA positively and negatively predicted both political intolerance and prejudice toward tradition-threatening and -reaffirming groups, respectively, whereas SDO positively and negatively predicted prejudice (and to some extent political intolerance) toward hierarchy-attenuating and -enhancing groups, respectively. Critically, the Conservatism component of RWA positively predicted political intolerance (but not prejudice) toward each type of target group, suggesting it captures the anti-democratic impulse at the heart of authoritarianism. Recommendations for future research on the relationship between ideological attitudes and inter-group antipathy are discussed. PMID:26377669

A total of 85 taxa were identified, 35 of them belonging to cyanobacteria, 30 chlorophytes, and 20 belonging to other groups of algae. Aerophytic cyanobacteria dominated in these calcareous habitats. Nine species, Gloeocapsa alpina, Nostoc commune, Chlorella vulgaris, Dilabifilum arthopyreniae, Klebsormidium flaccidum, Muriella decolor, Neocystis subglobosa, and Orthoseira roseana, were the most abundant taxa in all the caves. The investigated microhabitats offer relatively stable microclimatic conditions and are likely to be responsible for the observed vertical distribution of aerophytic cyanobacteria and algae.

    This report outlines a comprehensive training program for members of Native American tribes whose lands have oil and gas resources. The program has two components: short courses and internships. Programs are proposed for: (1) adult tribes representatives who are responsible for managing tribal mineral holdings, setting policy, or who work in the oil and gas industry; (2) graduate and undergraduate college students who are tribal members and are studying in the appropriate fields; and (3) high school and middle school teachers, science teachers. Materials and program models already have been developed for some components of the projects. The plan is a coordinated, comprehensive effort to use existing resources to accomplish its goals. Partnerships will be established with the tribes, the BIA, tribal organizations, other government agencies, and the private sector to implement the program.

    2015-01-01

    Full Text Available Background: Protein-energy malnutrition (PEM is a common complication in pediatric patients with chronic kidney disease (CKD. Components incorporated in the regulation of appetite and body composition appear to be of the focus in renal insufficiency and may influence the CKD-associated PEM. The purpose of this study was to investigate plasma levels of appetite-regulating hormones and their correlation with the body composition variables in a pediatric in predialysis stage of CKD. Methods: Thirty children with CKD in predialysis stage were selected and compared with 30 healthy sex- and age-matched controls. Blood samples were collected in fasting. Serum total ghrelin, leptin, and obestatin levels were measured using enzyme immunometric assay methods. Anthropometric parameters measurement and body composition analysis were done using the bioelectric impedance analysis (BIA method. Results: Patients showed insignificant elevated total ghrelin (105.40±30.83 ng/l, leptin (5.32±1.17 ng/ml and obestatin (5.07±1.09 ng/ml levels in comparison with healthy participants. By using BIA, patients had significantly different Dry Lean Weight (P=0.048, Extra Cellular Water (P=0.045, Body Cell Mass (BCM (P=0.021, Basal Metabolic Rate (P=0.033 and Body Mass Index (P=0.029 compared with controls. Furthermore, the total body water was slightly and the ECW was significantly higher in CKD participants. There were significant negative correlation between obestatin and BCM (r=-0.40, P=0.03 and fat free mass index (FFMI (r=-0.40, P=0.029 in patients. Conclusion: It seems that our results are insufficient to clarify the role of appetite-regulating hormones in PEM in CKD patients. It is apparent that there are still many unknown parameters related to both appetite regulating and CKD-associated PEM.

  1. Negative screening tests in classical galactosaemia caused by S135L homozygosity.

    Classical galactosaemia is relatively common in Ireland due to a high carrier rate of the Q188R GALT mutation. It is screened for using a bacterial inhibition assay (BIA) for free galactose. A Beutler assay on day one of life is performed only in high risk cases (infants of the Traveller community and relatives of known cases). A 16-month-old Irish-born boy of Nigerian origin was referred for investigation of developmental delay, and failure to thrive. He had oral aversion to solids and his diet consisted of cow\\'s milk and milk-based cereal mixes. He was found to have microcephaly, weight <2nd percentile, hepatomegaly and bilateral cataracts. Coagulation screen was normal and transaminases were slightly elevated. His original newborn screen was reviewed and confirmed to have been negative; urinary reducing substances on three separate occasions were negative. Beutler assay demonstrated "absent" red cell galactose-1-phosphate uridyltransferase (GALT) activity. GALT enzyme activity was <0.5 gsubs\\/h per gHb confirming classical galactosaemia. Gal-1-P was elevated at 1.88 micromol\\/gHb. Mutation analysis of the GALT gene revealed S135L homozygosity. S135L\\/S135L galactosaemia is associated with absent red cell GALT activity but with approximately 10% activity in other tissues such as the liver and intestines, probably explaining the negative screening tests and the somewhat milder phenotype associated with this genotype. The patient was commenced on galactose-restricted diet; on follow-up at 2 years of age, growth had normalized but there was global developmental delay. In conclusion, galactosaemia must be considered in children who present with poor growth, hepatomegaly, developmental delay and cataracts and GALT enzyme analysis should be a first line test in such cases. Non-enzymatic screening methods such as urinary reducing substances and BIA for free galactose are not reliable in S135L homozygous galactosaemia.

  2. Calibration of bioelectrical impedance analysis for body composition assessment in Ethiopian infants using air-displacement plethysmography

    2015-01-01

    BACKGROUND/OBJECTIVES: Assessment of infant body composition (BC) is crucial to understand the consequences of suboptimal nutritional status and postnatal growth, and the effects of public health interventions. Bioelectrical impedance analysis (BIA) is a feasible, relatively inexpensive and noninvasive method for assessing BC. However, very little research has been conducted in low- and middle-income populations, where efforts to prevent or treat malnutrition in early life are a public health priority. We aimed to develop equations for predicting fat-free mass (FFM) and fat mass (FM) based on BIA in 0- to 6-month-old Ethiopian infants. SUBJECTS/METHODS: The study comprised a total of 186 BC assessments performed in 101 healthy infants, delivered at Jimma University Specialized Hospital. Infant air-displacement plethysmography (IADP) was the criterion method, whereas weight, length, sex, age and an impedance index (L(2)/Z50) were predictors. Prediction equations were developed using stepwise multiple linear regression and the accuracy was evaluated with a 10-fold cross-validation approach. RESULTS: A linear regression model based on body weight, age and sex predicted FFM, estimated by IADP, with an adjusted R(2) and root mean square error (RMSE) of 0.94 and 200?g, respectively. Adding impedance index to the model resulted in a significantly improved model fit (R(2)=0.95; RMSE=181?g). For infants below 3 months of age, inclusion of impedance index did not contribute to an improved model fit for predicting FFM compared with a model already comprising weight, sex and age. CONCLUSIONS: The derived equations predicted FFM with acceptable accuracy and may be used in future field surveys, epidemiological studies and clinical trials conducted in similar sub-Saharan African population groups aged 0-6 months.European Journal of Clinical Nutrition advance online publication, 1 April 2015; doi:10.1038/ejcn.2015.51.

  3. Assessment and monitoring of nutrition status in pediatric peritoneal dialysis patients.

    2009-02-01

    Abnormalities of nutrition status are a common problem in children on peritoneal dialysis (PD) and a source of significant morbidity and mortality. The state of decreased body protein mass and fuel reserves (body protein and fat mass) common in PD patients is now better known as protein-energy wasting (PEW). Protein-energy wasting is a slow, progressive process in chronic kidney disease. The correct approach to this problem includes measurement of early, intermediate, and late markers of PEW, and consideration of the risk factors specific to the patient and to PD. The earliest markers of PEW are associated with some symptoms observed clinically: a decrease in dietary intake and an increase in inflammatory markers. The second stage in the development of PEW (patients with established PEW) is characterized by abnormalities in numerous markers: bioimpedance analysis (BIA) and anthropometric indices, other indices of body mass and composition, biochemical parameters, and indices of protein, glucose, and lipid metabolism. When PEW is established, clear clinical signs become evident: patients in this stage are characterized by high rates of hospitalization and an increased risk for morbidity and mortality as compared with patients without cachexia. Risk factors for PEW can already be present in an apparently well-nourished child who initiates PD: glucose absorption from PD fluid, abdominal distension from PD volume, gastroesophageal reflux, and even more importantly, inadequate dialysis dose in relation to decline in residual renal function. Given the complexity of the pathogenesis and clinical picture of PEW, no single measure, but rather panels of nutritional measures are necessary to diagnose the condition. Combined nutrition scores such as the anthropometry-BIA nutrition score may add value to the monitoring of nutrition status in children on PD. PMID:19270211

Healthy subjects (34 men and 30 women) were measured by two methods: bone mineral content (BMC) was measured by a commercial body composition analyser and bioelectrical impedance at various frequencies was measured by a newly developed bioelectrical impedance measurement system. As correlations were high and prediction error was low, a single equation was developed using all subjects as follows: BMC?=?-3.5268?+?(0.0279? x ?h)?+?(0.0145? x ?w)?+?(184? x ?(h²/Z(body50)))-(1.08? x ?(w x ?h²/Z(body6.25)))-(0.0032? x ?(age))-(0.103? x ?(sex); men?=?1, women?=?0). BMC measured from commercial instrument InBody720 was 2.552?±?0.457 kg. BMC predicted by equation was 2.554?±?0.447 kg (R?=?0.976, adjusted R²?=?0.948, standard error of estimate?=?0.104 kg, total error?=?0.09987 kg). The results of this study show that the newly developed multi-frequency bioelectrical impedance measurement system with the single prediction BIA equation can be used in screening the subjects suspected with osteoporosis and for follow-up study of the patient under the therapy for osteoporosis. For validation of commercial instrument InBody720, BMC of 22 healthy subjects was measured by InBody720 and dual-energy X-ray absorptiometry. High correlation (R?=?0.9531) and low error (total error?=?0.0913 kg) was found between these two methods. PMID:21231827

    Full Text Available Introduction Visceral leishmaniasis (VL is caused by the intracellular protozoan Leishmania donovani complex. VL may be asymptomatic or progressive and is characterized by fever, anemia, weight loss and the enlargement of the spleen and liver. The nutritional status of the patients with VL is a major determinant of the progression, severity and mortality of the disease, as it affects the clinical progression of the disease. Changes in lipoproteins and plasma proteins may have major impacts in the host during infection. Thus, our goal was evaluate the serum total cholesterol, high-density lipoprotein (HDL, low-density lipoprotein (LDL, triglycerides, glucose, albumin, globulin and total protein levels, as well as the body composition, of VL patients before and after treatment. Methods Nutritional evaluation was performed using the bioelectrical impedance analysis (BIA to assess body composition. Biochemical data on the serum total cholesterol, HDL, LDL, triglycerides, glucose, albumin, globulin and total protein were collected from the medical charts of the patients. Results BIA indicated that both pre-treatment and post-treatment patients exhibited decreased phase angles compared to the controls, which is indicative of disease. Prior to treatment, the patients exhibited lower levels of total body water compared to the controls. Regarding the biochemical evaluation, patients with active VL exhibited lower levels of total cholesterol, HDL, LDL and albumin and higher triglyceride levels compared to patients after treatment and the controls. Treatment increased the levels of albumin and lipoproteins and decreased the triglyceride levels. Conclusions Our results suggest that patients with active VL present biochemical and nutritional changes that are reversed by treatment.

Materials and methods: Collagen, [3H]-thymidine incorporation, and prolidase activity were measured in confluent human skin fibroblast cultures that had been treated with 1, 2, and 5 mM caffeine and with caffeine and 500 µg/mL HA. Western immunoblot analysis was performed to evaluate expression of ß1-integrin receptor, insulin-like growth factor receptor phospho-Akt protein and mitogen-activated protein kinase (phospho-extracellular signal-regulated kinase. Results: Caffeine inhibited collagen biosynthesis in a dose-dependent manner. The mechanism of this process was found at the level of prolidase activity. Caffeine significantly inhibited the enzyme activity. The addition of HA had no effect on collagen biosynthesis or prolidase activity in fibroblasts incubated with caffeine. Caffeine also had an inhibitory effect on DNA biosynthesis. HA, however, did not have any significant effect on this process. The inhibition of the expression of ß1-integrin and insulin-like growth factor receptor in fibroblasts incubated with the caffeine indicates a possible mechanism of inhibition of collagen biosynthesis. Conclusion: Caffeine reduces collagen synthesis in human cultured skin fibroblasts. HA did not have any significant protective effect on this process. This is the first study to our knowledge that reports caffeine-induced inhibition of collagen synthesis in human skin fibroblasts. Keywords: collagen, caffeine, hyaluronic acid, fibroblast

    Disability is a serious social, cultural and economic problem, the solving of which requires both legal regulations and coordinated activities by the State. A constantly increasing number of the disabled is an important premise for undertaking actions aimed at complex rehabilitation of this population group, and their engagement in social and economic life. Creating possibilities for spending free time in an attractive way, in accordance with ones interests and needs, is an essential area of rehabilitation activities. In 2005, the Institute of Tourism and Recreation at the State Higher Vocational School in Bia? Podlaska launched representative, complex studies concerning the social conditioning of involvement of the disabled from the regions of Eastern Poland in tourism and mobile recreation. The presented material is an excerpt from this study report. It concerns barriers which limit or make it impossible for disabled males and females to participate in tourism and mobile recreation in the regions of Lublin, Rzeszow, and Bia?stok. Among barriers, which to the highest degree limit the participation of the disabled in tourism and recreation, the respondents indicated their poor material standard. Other important barriers were inconveniences associated with transport, lack of up-to-date information, and type of disability. The barriers limiting motor activity were also analyzed according to gender. Statistically significant differences were observed between males and females with respect to the following characteristics: transport, lack of adequate information, lack of off er of activities, and lack of assistance. It is noteworthy that males more strongly than females emphasized such barriers as lack of information, off er of assistance, while females indicated the problems with transport. PMID:22216812

    The porphyrias are a group of rare metabolic disorders. The incidence and prevalence are low because the acute intermittent porphyria (AIP) is rare. Our aim was to assess the use of anthropometric and quality-of-life parameters in porphyric patients in order to identify predictor factors that might help in characterizing AIP patients.Sixteen AIP patients from Murcia (Spain) were recruited from local health centers in 2008 and 2009. A control group of 16 healthy people was established. Body composition was assessed by bioelectrical impedance analysis (BIA) and anthropometric measurements: body weight; height; knee-heel height; waist, hip, upper arm and calf circumferences (CCs); biacromion and biiliac diameters; bicondylar and biepicondylar width; and triceps, subscapular, supraspinale, and calf skinfold thickness. Anthropometric indicators were obtained from anthropometric measurements. A quality-of-life evaluation was carried out using the EuroQol-5D (EQ-5D) questionnaire and Barthel and Katz indexes. Significant differences in means were tested by unpaired Student t test. Group differences in anthropometric measurements were tested with a 2-way analysis of variance (group?×?condition: age group, overweight, and adiposity degree). Relative frequencies were obtained for noncontinuous variables. Significant differences in prevalence were calculated by means of ?.AIP patients showed statistically significant differences in terms of knee-heel height, biiliac diameter, CC, triceps skinfold thickness, BIA, ponderal index, endomorphy, and ectomorphy. Only 1 quality-of-life indicator, visual analog scale, in the EQ-5D questionnaire showed significant differences between porphyric and control groups.Some anthropometric parameters and the EQ-5D questionnaire could be used to appreciate the presence or follow the evolution of the disease in AIP patients.

    Full Text Available A intensidade da cor verde da folha pode ser alternativa para estimar a concentração de N na planta, devido à relação entre o teor de clorofila e o de N no tecido foliar. Objetivou-se neste trabalho avaliar índices da cor verde da grama esmeralda obtidos da análise da imagem digital e pelo uso do cl [...] orofilômetro para predizer o estado nutricional em N fornecido pelo lodo de esgoto. O experimento foi instalado e desenvolvido em uma propriedade comercial de grama esmeralda, localizada na cidade de Itapetininga (SP). O delineamento experimental foi em blocos casualizados, com quatro repetições e cinco doses de lodo de esgoto: 0, 10, 20, 30 e 40 Mg ha-1, base seca. As doses de lodo aplicadas correspondem a 100, 200, 300 e 400 kg ha-1 de nitrogênio disponível. Foram avaliadas as concentrações de N e a intensidade de coloração verde da folha pelo uso do clorofilômetro (ICV) e por meio da análise da imagem digital (G, H e ICVE) aos 45, 105 e 165 dias após a aplicação do lodo. Os valores de intensidade obtidos foram correlacionados com a concentração de N na lâmina foliar e com a taxa de cobertura do solo determinada nas mesmas épocas. A aplicação de doses de lodo de esgoto proporcionou aumento dos índices de cor verde e da concentração de N nas folhas da grama esmeralda. A concentração de N na lâmina foliar pode auxiliar a adubação nitrogenada em cobertura, pois proporcionou altas correlações com a taxa de cobertura do solo. O matiz (H) obtido com a imagem digital e a intensidade de cor verde da folha (ICV) obtida com o clorofilômetro correlacionaram-se com a concentração de N e com a taxa de cobertura do solo e, dessa forma, podem servir como índices na recomendação da adubação nitrogenada.

The experiment was carried out on a commercial property of zoysiagrass, located in the county of Itapetininga, State of São Paulo. The experimental design was completely randomized, with five sewage sludge doses: 0, 10, 20, 30 and 40 Mg ha-1, on dry basis (equal to 0, 100, 200, 300 and 400 kg ha-¹) of N available and four replications. The N concentration and green hue intensity were evaluated by using chlorophyll meter (GHI) and by the digital image analysis (G, H and DGCI) at 45th, 105th and the 165th days after sewage sludge application. The intensity values were correlated with the N concentration in the leaf blade and with the soil cover rate determined in the same season. The application of sewage sludge doses increased the green rates and the N concentration in the Zoysia grass leaves. The N concentration leaf can help the nitrogen top-dressed application because it has high correlation with the soil cover rate. The hue (H) obtained with the digital image and green hue intensity (GHI) obtained with the chlorophyll meter are correlated with N concentration and with the soil cover rate and can serve as an index to assist in the recommendation of nitrogen fertilization.

  20. Prototype Tsunami Evacuation Park in Padang, West Sumatra, Indonesia

    Padang, Indonesia, a city of some 900,000 people, half of whom live close to the coast and within a five-meter elevation above sea level, has one of the highest tsunami risks in the world due to its close offshore thrust-fault seismic hazard, flat terrain and dense population. There is a high probability that a tsunami will strike the shores of Padang, flooding half of the area of the city, within the next 30 years. If that tsunami occurred today, it is estimated that several hundred thousand people would die, as they could not reach safe ground in the ~30 minute interval between the earthquake's occurrence and the tsunami's arrival. Padang's needs have been amply demonstrated: after earthquakes in 2007, 2009, 2011 and 2012, citizens, thinking that those earthquakes might cause a tsunami, tried to evacuate in cars and motorbikes, which created traffic jams, and most could not reach safe ground in 30 minutes. Since 2008, GeoHazards International (GHI) and Stanford University have studied a range of options for improving this situation, including ways to accelerate evacuation to high ground with pedestrian bridges and widened roads, and means of "vertical" evacuation in multi-story buildings, mosques, pedestrian overpasses, and Tsunami Evacuation Parks (TEPs), which are man-made hills with recreation facilities on top. TEPs proved most practical and cost-effective for Padang, given the available budget, technology and time. The Earth Observatory Singapore (EOS) developed an agent-based model that simulates pedestrian and vehicular evacuation to assess tsunami risk and risk reduction interventions in Southeast Asia. EOS applied this model to analyze the effectiveness in Padang of TEPs over other tsunami risk management approaches in terms of evacuation times and the number of people saved. The model shows that only ~24,000 people (20% of the total population) in the northern part of Padang can reach safe ground within 30 minutes, if people evacuate using cars and motorbikes immediately after the earthquake. If one TEP is built, ~46,000 could reach safe ground within 30 minutes, and if three were built ~72,000 could. GHI has acquired permission to build a prototype TEP in the northern part of Padang that would accommodate about 25,000 people during the time of a tsunami. This would cost about 4.7 million, amounting to a cost-per-life-saved of ~US200, far lower than the per capita cost of the other options. The cost of replication should be less. This interdisciplinary, international effort demonstrated that TEPs offer the best option for Padang because they have the potential to save thousands of lives, are relatively simple to build and maintain, invite everyday recreational use by the community, and have attracted strong Indonesian government support as a possible means to manage the country's tsunami risk.

    Four new donor-acceptor triads (D-A-D) based on discotic and arylene mesogens have been synthesized by using Sonogashira coupling and cyclization reactions. This family of triads consists of two side-on pending triphenylene mesogens, acting as the electron-donating groups (D), laterally connected through short lipophilic spacers to a central perylenediimide (PI), benzo[ghi]perylenediimide (BI), or coronenediimide (CI) molecular unit, respectively, playing the role of the electron acceptor (A). All D-A-D triads self-organize to form a lamello-columnar oblique mesophase, with a highly segregated donor-acceptor (D-A) heterojunction organization, consequent to efficient molecular self-sorting. The structure consists in the regular alternation of two disrupted rows of triphenylene columns and a continuous row of diimine species. High-resolution STM images demonstrate that PI-TP2 forms stable 2D self-assembly nanostructures with some various degrees of regularity, whereas the other triads do not self-organize into ordered architectures. The electron-transport mobility of CI-TP2, measured by time-of-flight at 200?°C in the mesophase, is one order of magnitude higher than the hole mobility. By means of this specific molecular designing idea, we realized and demonstrated for the first time the so-called p-n heterojunction at the molecular level in which the electron-rich triphenylene columns act as the hole transient pathways, and the coronenediimide stacks form the electron-transport channels.

    Infrared spectroscopic studies of ultraviolet (UV) irradiated, water-rich, cosmic ice analogs containing small polycyclic aromatic hydrocarbons (PAHs) are described. The irradiation studies of anthracene:H{sub 2}O, pyrene:H{sub 2}O, and benzo[ghi]perylene:H{sub 2}O ices (14 K) at various concentrations reported by Bouwman et al. are extended. While aromatic alcohols and ketones have been reported in residues after irradiated PAH:H{sub 2}O ices were warmed to 270 K, it was not known if they formed during ice irradiation or during warm-up when reactants interact as H{sub 2}O sublimes. Recent work has shown that they form in low temperature ice. Using DFT computed IR spectra to identify photoproducts and PAH cations, we tentatively identify the production of specific alcohols [PAH(OH) {sub n} ] and quinones [PAH(O) {sub n} ] for all PAH:H{sub 2}O ices considered here. Little evidence is found for hydrogenation at 14 K, consistent with the findings of Gudipati and Yang. Addition of O and OH to the parent PAH is the dominant photochemical reaction, but PAH erosion to smaller PAHs (producing CO{sub 2} and H{sub 2}CO) is also important. DFT spectra are used to assess the contribution of PAH-related species to interstellar absorption features from 5 to 9 ?m. The case is made that PAH cations are important contributors to the C2 component and PAH(OH) {sub n} and PAH(O) {sub n} to the C5 component described by Boogert et al. Thus, interstellar ices should contain neutral and ionized PAHs, alcohols, ketones and quinones at the ?2%-4% level relative to H{sub 2}O. PAHs, their photoproducts, and ion-mediated processes should therefore be considered when modeling interstellar ice processes.

    Microparticles found in the air may be associated with organic matter that contains several compounds, such as Polycyclic Aromatic Hydrocarbons (PAHs) and nitro-PAHs, and may pose a significant risk to human health, possibly leading to DNA mutations and cancers. This study associated genotoxicity assays for evaluating human exposure with the atmospheric air of two urban areas in southern Brazil, that received different atmospheric contributions. Site 1 was under urban-industrial influence and the other was a non-industrial reference, Site 2. Organic extracts from the airborne particulate matter were tested for mutagenicity via the Salmonella/microsome assay and analyzed for PAH composition. Cells samples of people residing in these two cities were evaluated using the comet and micronucleus assay (MN).Concentrations of the individual PAHs ranged from 0.01 ng/m(3) (benzo[a]anthracene) to 5.08 ng/m(3) (benzo[ghi]perylene). As to mutagenicity analysis of airborne, Site 1 presented all the mutagenic responses, which varied from 3.2±1.22 rev/m(3) (TA98 no S9) to 32.6±2.05 rev/m(3) (TA98, S9), while Site 2 ranged from negative to minimal responses. Site 1 presented a high quantity of nitro and amino derivatives of PAHs, and peaked at 56.0±3.68 rev/?g (YG1024 strain). The two groups presented very low DNA damage levels without intergroup difference. Although Site 1 presented high mutagenic responses in the air samples, high PAH levels, healthy people exposed to this environment did not show significative damage in their genetic material. However, the evaluation of different environmental and genetic damage in such population is necessary to monitor possible damages. PMID:23395453

    Size-resolved particulate matter emissions from pine, California oak, east coast oak, eucalyptus, rice straw, cigarette smoke, and meat cooking were analyzed for trace organic species using solvent-extraction followed by GC-MS analysis. Six particle size fractions were studied between 0.056, 0.1, 0.18, 0.32, 0.56, 1.0, and 1.8 ?m particle diameter. The smallest particle size fraction analyzed was in the ultrafine (Dprice straw smoke with the most abundant compound (benzo[ a]pyrene) emitted at 0.01 (mg kg -1 rice straw burned). The most abundant PAH measured in the ultrafine size fraction of cigarette smoke was benzo[ ghi]fluoranthene (0.07 mg cigarette -1) followed closely by chrysene/triphenylene (0.06 mg cigarette -1). Besides PAHs, the most abundant compounds identified in the wood included levoglucosan (0.9) with the size distribution of particle-phase organic carbon (OC) and/or elemental carbon (EC). The only organic compounds besides PAHs detected in the ultrafine size fraction of rice straw and cigarette smoke were benz[ de]anthracen-7-one (0.19 mg kg -1 rice straw burned) and 4-methylphenylacetone (2.64 mg cigarette -1), respectively. Caffeine was measured in cigarette smoke size fractions >0.1 ?m with a total PM 1.8 emissions rate of 1 (mg cigarette -1). The most abundant organic species measured in meat cooking smoke was cholesterol with a size distribution that was highly correlated with both OC and EC. The concentration of each compound normalized by the concentration of total OC was relatively uniform for all particle sizes. Cholesterol and levoglucosan should prove to be useful tracers for meat cooking and wood smoke emissions in the ultrafine size range.

    Airborne particulates were collected in seven cities in the Pan-Japan Sea countries, Shenyang (China), Vladivostok (Russia), Seoul (South Korea), Kitakyushu, Kanazawa, Tokyo and Sapporo (Japan), in winter and summer from 1997 to 2002. In addition, particulates from domestic coal-burning heaters and diesel engine automobiles were collected in Shenyang and Kanazawa, respectively. Nine polycyclic aromatic hydrocarbons (PAHs) and four nitropolycyclic aromatic hydrocarbons (NPAHs) in the extracts from the particulates were analysed by HPLC with fluorescence and chemiluminescence detections, respectively. The PAHs were fluoranthene, pyrene (Pyr), benz[ a]anthracene, chrysene, benzo[ b]fluoranthene, benzo[ k]fluoranthene, benzo[ a]pyrene, benzo[ ghi]perylene and indeno[1,2,3- cd]pyrene, and NPAHs were 1,3-, 1,6-, 1,8-dinitropyrenes, and 1-nitropyrene (1-NP). Mean atmospheric concentrations of PAHs in Shenyang and Vladivostok were substantially higher than those in Seoul, Tokyo, Sapporo, Kitakyushu and Kanazawa. However, the mean atmospheric concentrations of NPAHs were at the same levels in all cities except Kitakyushu. The expected seasonal variations (greater PAH and NPAH concentrations in winter than in summer) were observed in all cities. In order to study the major contributors of atmospheric PAHs and NPAHs, both cluster analysis and factor analysis were used and three large clusters were identified. Furthermore, the concentration ratios of 1-NP to Pyr were significantly smaller in Shenyang, Vladivostok and Kitakyushu and the values were close to those observed in particulates from coal stove exhaust. By contrast, in Seoul, Kanazawa, Tokyo and Sapporo the [1-NP]/[Pyr] ratio reached values similar to those of particulates released from diesel-engine automobiles. The [1-NP]/[Pyr] concentration ratio seemed to be a suitable indicator of the contribution made by diesel-engine vehicles and coal combustion to urban air particulates.

    Semi-volatile compounds present special analytical challenges not met by conventional methods for analysis of ambient particulate matter (PM). Accurate quantification of PM-associated organic compounds requires validation of the laboratory procedures for recovery over a wide volatility and polarity range. To meet these challenges, solutions of n-alkanes (nC{sub 12} to nC{sub 40}) and polycyclic aromatic hydrocarbons PAHs (naphthalene to benzo[ghi]perylene) were reduced in volume from a solvent mixture (equal volumes of hexane, dichloromethane and methanol), to examine recovery after reduction in volume. When the extract solution volume reached 0.5 mL the solvent was entirely methanol, and the recovery averaged 60% for n-alkanes nC{sub 12} to nC{sub 25} and PAHs from naphthalene to chrysene. Recovery of higher MW compounds decreased with MW, because of their insolubility in methanol. When the walls of the flasks were washed with 1 mL of equal parts hexane and dichloromethane (to reconstruct the original solvent composition), the recovery of nC{sub 18} and higher MW compounds increased dramatically, up to 100% for nC{sub 22}-nC{sub 32} and then slowly decreasing with MW due to insolubility. To examine recovery during extraction of the components of the High Capacity Integrated Gas and Particle Sampler, the same standards were used to spike its denuders and filters. For XAD-4 coated denuders and filters, normalized recovery was > 95% after two extractions. Recovery from spiked quartz filters matched the recovery from the coated surfaces for alkanes nC{sub 18} and larger, and for fluoranthene and larger PAHs. Lower MW compounds evaporated from the quartz filter with the spiking solvent. This careful approach allowed quantification of organics by correcting for volatility- and solubility-related sample preparation losses. This method is illustrated for an ambient sample collected with this sampler during the Texas Air Quality Study 2000.

  8. Characterization of polycyclic aromatic hydrocarbons (PAH's) present in sampled cooked food

    International Nuclear Information System (INIS)

    The study was conducted to determine the levels of Polycyclic Aromatic Hydrocarbons in the following traditionally prepared food: smoked and grilled Scomba japonicus, grilled meat (khebab) and bread sampled from some Ghanaian markets. By way of preparation of traditional food, some food comes into direct contact with smoke or extremely high temperature which are potential sources of Polycyclic Aromatic Hydrocarbon generation. Levels of 20 individual Polycyclic Aromatic Hydrocarbons including acenaphthene, acenaphtyelene, anthanthrene, anthracene, benz(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, benzo(e)pyrene, benzo(ghi)perylene, benzo(j)fluoranthene, benzo(k)fluoranthene, chrysene, cyclopenta(cd)pyrene, dibenzo(ah)anthracene, fluoranthene, fluorene, indeno(1,2,3-cd)pyrene, naphthalene, phenanthrene and pyrene were determined in 11 smoked and 5 grilled fish, 4 grilled pieces of meat and 3 loaves of baked bread using gas chromatographic techniques with flame ionization detector. Benzo(a)pyrene, which is one of the few PAH for which a legal limit exists in different types of food matrices and other high molecular weight PAHs suspected to be carcinogenic have been detected in high concentrations in most samples. Bread samples gave mean polycyclic aromatic hydrocarbon concentrations of up to 20.39 ?g/kg while khebab samples gave mean polycyclicaromatic hydrocarbon concentrations of up to 67.61 ?g/kg. There was positive correlation of 0.987 between levels of polycyclic aromatic hydrocarbon concentrations in khebab samples from locations Osu and Atomic down. There was a positive correlation in the concentrations of the high molecular weight PAHs in all smoked fishes from four locations with values between 0.954 and 0.999 for the correlation between any two groups. The polycyclic aromatic hydrocarbon concentration determined in smoked fish samples deceased in terms of location according to the order Winneba > Madina > Chorkor > Ada.

    Full Text Available India launched Jawaharlal Nehru National Solar Mission in 2009, which aims to set up 20 000 MW of grid connected solar power, besides 2 000 MW equivalent of off-grid applications and cumulative growth of solar thermal collector area to 20 million m2 by 2022. Availability of reliable and accurate solar radiation data is crucial to achieve the targets. As a result of this initiative, Ministry of New and Renewable Energy (MNRE of Government of India (GoI has awarded a project to Centre for Wind Energy Technology (C-WET, Chennai in the year 2011 to set up 51 Solar Radiation Resource Assessment (SRRA stations using the state-of-the-art equipment in various parts of the country, especially the sites with high potential for solar power. The GoI project has synergy with SolMap project, which is implemented by the Deutsche GesellschaftfürInternationaleZusammenarbeit (GIZ in cooperation with the MNRE. SolMap project is contributing to SRRA project in establishing quality checks on the data obtained as per International protocols and helping data processing to generate investment grade data. The paper highlights the details of SRRA stations and an attempt has been made to present some of the important results of quality control and data analysis with respect to GHI and DNI. While our analysis of the data over one year finds that intensity and profile of the insolation are not uniform across the geographic regions, the variability in DNI is particularly high. Strong influence of monsoon is also identified. SRRA infrastructure aims to develop investment grade solar radiation resource information to assist project activities under the National Solar Mission of India.

    In the 1980s long-lived radical species were identified in cigarette tar. Since then, environmentally persistent free radicals (EPFRs) have been observed in ambient particulate matter, and have been generated in particulate matter generated from internal combustion engines. For the first time, we measure in situ the formation and decay of EPFRs through the heterogeneous reaction of ozone and several polycyclic aromatic compounds (PAC). Solid anthracene (ANT), pyrene (PY), benzo[a]pyrene (BAP), benzo[ghi]perylene (BGHIP), 1,4-naphthoquinone (1,4NQ), and 9,10-anthraquinone (AQ) were reacted with gas-phase ozone in a flow system placed in the active cavity of an electron paramagnetic resonance (EPR) spectrometer, and the formation of radicals was measured on the timescale of tens of minutes at ambient levels of ozone down to 30 ppb. For most substrates the net radical production is initially rapid, slows at intermediate times, and is followed by a slow decay. For oxidized solid BAP, radical signal persists for many days in the absence of ozone. To evaluate the effect of substrate phase, the solid PAHs were also dissolved in squalane, an organic oil inert to ozone, which yielded a much higher maximum radical concentration and faster radical decay when exposed to ozone. With higher mobility, reactants were apparently able to more easily diffuse and react with each other, yielding the higher radical concentrations. The EPR spectra exhibit three radicals types, two of which have been assigned to semiquinone species and one to a PAH-derived, carbon-centered radical. Although our system uses levels of PAC not typically found in the environment it is worth noting that the amounts of radical formed, on the order of 10(18) radicals per g, are comparable to those observed in ambient particulate matter.

  11. Determination of polycyclic aromatic hydrocarbons in airborne

    International Nuclear Information System (INIS)

    Rainfall polycyclic aromatic hydrocarbons (PAH) concentrations were determined in particulate matter with a <10 mm aerodynamic diameter (PM10) in three industrial municipalities of the metropolitan zone of Bogota City (MZBC). The 12 samples of greatest concentration of PM10 collected between 2001 and 2002 at the stations of atmospheric monitoring of Cundinamarca secretary of health (SSC), in the municipalities of Soacha, Sibate and Cajica, were analyzed. The results were correlated with emissions in the area, by means of emission factors and environmental agencies information. The particulate matter results for the analyzed period show concentrations that exceed the air quality standard of the US environmental protection agency EPA on several occasions at the Soacha municipality, whereas the air quality in the Sibate and Cajica municipalities did not show that to be the case. Despite the reduced number of samples and sampling sites, we believe that the reported profiles can be considered a valid estimation of the average air quality of the MZBC. The identified PAH species were: phenanthrene(Phe), anthracene(Ant), fluoranthene(Fla), pyrene(Pyr), benzo(a)anthracene (Baa), chrysene(chr), benzo(ghi)perylene(BgP) and indeno(1,2,3-cd)pyrene(Ind). It was not possible to quantify naphthalene (Nap), acenaphthy-lene(Acy), acenaphthene(Ace), nor fluorene(Flu), being light and volatile hydrocarbons with greater presence in the gaseous phase of the air. The correlation of PAH with source emissions shows mobile sources to be the main origin. The intervals of concentration of both individual PAH and the total species were similar to the ones usually found in other industrial zones of the world. PAHs correlations allowed pinpointing common emission sources between Soacha and Sibate municipalities

Conclusiones: Llegamos a la conclusión de que la AF es una herramienta relevante la evaluación nutricional en la hepatitis crónica, cirrosis hepática y carcinoma hepatocelular y el papel de la AF en la predicción de la supervivencia de la EPC debe seguir siendo examinado en estudios controlados. Abstract in english Introduction: Malnutrition is commonly and frequently under-diagnosed in clinical settings in patients with chronic liver disease (CLD) due to the limitations of nutritional evaluation methods in this population. We hypothesized that the bioelectrical impedance analysis derived phase angle (BIA-deri [...] ved PhA) might be considered as a nutritional indicator in CLD since it represents either cell death or malnutrition characterized by changes in cellular membrane integrity. Objective: The aim of this study was to evaluate the BIA-derived PhA as a nutritional evaluation tool in all stages of CLD, including chronic hepatitis, liver cirrhosis and hepatocellular carcinoma (HCC). Liver-related death and survival were evaluated. Methods: A total of 66 patients were enrolled in a cross-sectional study. For the nutritional diagnosis, mid-arm circumference (MAC), triceps skinfold thickness (TST), mid-arm muscle circumference (MAMC) and Subject Global Assessment (SGA) were evaluated. Biochemical and clinical evaluations were performed. Results: Our results showed that PhA was higher in well-nourished patients, according to SGA and in the patients without hepatic encephalopathy. PhA correlated significantly with MAMC, MAC and albumin and was inversely correlated with age. No correlation was found between PhA values and the Child-Pugh score and ascites. PhA was strongly associated with survival and PhA ? 5.18º with relative risk increase of 2.5 for death. Conclusions: We conclude that the BIA-derived PhA is a relevant nutritional evaluation tool in chronic hepatitis, liver cirrhosis and HCC and the role of PhA in the prediction of survival in CLD should be examined further in a controlled study.

    Full Text Available "...So I Decided to Be a Pole..."Conclusions like the one in the headline had been given by several of my interviewees when being asked about their own ethnic identity. But the respondents are no inhabitants of Poland, they live in the Western parts of Belarus or Eastern Lithuania, in areas that belonged to Poland between the world wars. In many of their familyhistories we can still observe the mosaic of nationalities and languages that used to characterize this area and to a certain extent is present until today. All of the persons I present declared to be Polish. But there are various ways of how they describe their Polishness: they came by different ways to the decision or belief that they are Poles. In some cases we can remark a conscious creation of one’s own ethnic identity, some even describe a moment in their lives, when they decided to be a Pole. Others were brought up as Poles and never questioned that they could be someone else. Some declare to be more Polish than Poles in Poland, others call themselves no real Poles and wish to be as Polish as people in Warsaw in their eyes are. So there are big differences between individual interviewees, but also between families, regions and the two countries, Lithuania and Belarus. In all cases my interviewees present themselves in dissociation with the Belarusian or Lithuanian majority-culture and language, but also feel a difference between themselves and the inhabitants of the country of reference, Poland. In the paper I present different ways of how people construct and define their “being Polish” while belonging to an ethnic minority. „...A wi?c postanowi?em by?

The subjects were divided into three groups: residents of long-term care institutions (group I, residents of adult day-care homes (group II, and community-dwelling subjects (group III. Each group consisted of 100 subjects. Questionnaires evaluating the following physical and mental dimensions of health were used: SF-36 Health Survey, basic activities of daily living, instrumental activities of daily living, Geriatric Depression Scale, and Mini–mental state examination.Results: It was found that the health aspects of the elderly varied depending on whether care was provided in an institutionalized or a home environment, and the lowest health status was found in the elderly receiving in-home care. Furthermore, home-based elderly indicated significant limitations in performing basic activities of daily living and instrumental activities of daily living, as well as a higher prevalence of depression and cognitive impairment.Conclusion: The elderly in long-term institutionalized care, both in a residential home and adult day-care homes, were characterized by a better physical and mental health status than those receiving in-home care. It seemed that worse health status, including the more frequent depression occurrence and cognitive function disorders in the elderly using the nursing care at their homes, was related to their multimorbidity, loneliness, and too-short duration of the care during the day.

    Full Text Available Abstract Background Established risk factors for prostate cancer have not translated to effective prevention or adjuvant care strategies. Several epidemiologic studies suggest greater body adiposity may be a modifiable risk factor for high-grade (Gleason 7, Gleason 8-10 prostate cancer and prostate cancer mortality. However, BMI only approximates body adiposity, and may be confounded by centralized fat deposition or lean body mass in older men. Our objective was to use bioelectric impedance analysis (BIA to measure body composition and determine the association between prostate cancer and total body fat mass (FM fat-free mass (FFM, and percent body fat (%BF, and which body composition measure mediated the association between BMI or waist circumference (WC with prostate cancer. Methods The study used a multi-centered recruitment protocol targeting men scheduled for prostate biopsy. Men without prostate cancer at biopsy served as controls (n = 1057. Prostate cancer cases were classified as having Gleason 6 (n = 402, Gleason 7 (n = 272, or Gleason 8-10 (n = 135 cancer. BIA and body size measures were ascertained by trained staff prior to diagnosis, and clinical and comorbidity status were determined by chart review. Analyses utilized multivariable linear and logistic regression. Results Body size and composition measures were not significantly associated with low-grade (Gleason 6 prostate cancer. In contrast, BMI, WC, FM, and FFM were associated with an increased risk of Gleason 7 and Gleason 8-10 prostate cancer. Furthermore, BMI and WC were no longer associated with Gleason 8-10 (ORBMI = 1.039 (1.000, 1.081, ORWC = 1.016 (0.999, 1.033, continuous scales with control for total body FFM (ORBMI = 0.998 (0.946, 1.052, ORWC = 0.995 (0.974, 1.017. Furthermore, increasing FFM remained significantly associated with Gleason 7 (ORFFM = 1.030 (1.008, 1.052 and Gleason 8-10 (ORFFM = 1.044 (1.014, 1.074 after controlling for FM. Conclusions Our results suggest that associations between BMI and WC with high-grade prostate cancer are mediated through the measurement of total body FFM. It is unlikely that FFM causes prostate cancer, but instead provides a marker of testosterone or IGF1 activities involved with retaining lean mass as men age.

Com o avanço no conhecimento das enzimas, a utilização dos fungos como fonte de enzimas vem adquirindo um status de destaque nas mais variadas áre [...] as industriais e comerciais. Diante disso, o presente estudo procurou identificar a presença de atividade amilolítica em quatro linhagens do fungo filamentoso Aspergillus nidulans, selvagem, PAT, biA1methG1 e CLB3, utilizando dois meios distintos de cultura, BDA e Meio Completo a 2% amido, variando os tratamentos com adição ou não de glicose. Foram determinados o diâmetro médio da colônia, o diâmetro médio do halo e o Índice Enzimático. Como resultados, todas as linhagens testadas foram capazes de degradar o amido quando na ausência de glicose, porém o tratamento que obteve estatisticamente melhor crescimento e maior degradação do amido foi o MC sem glicose a 2% amido e a linhagem que se demonstrou potencialmente degradadora de amido foi o mutante CLB3. Conclui-se, portanto, que Aspergillus nidulans pode ser considerado como um produtor de amilases. Abstract in english The amylases are among the most important industrial enzymes showing great biotechnological importance, mainly in the food industry. Due to the advance knowledge in enzyme research, the use of fungi as source of enzymes has acquired a prominent status in most varied industrial and commercial areas. [...] Thus, the present study tried to identify the presence of the amylolytic activity in four stains of filamentous fungi Aspergillus nidulans, selvagem, PAT, biA1methG1 and CLB3 by using two different culture means, PDA and Complete mean with 2% starch, varying the treatments with and without the addition of glucose. The colony average diameter, the halo average diameter, and the enzymatic index were determined. The results show that all strains tested were capable of degrading starch in the absence of glucose although the treatment that presented statistically better growing and bigger degradation of starch was CM without glucose with 2% starch and the strain that demonstrated potentially degradation was CLB3 mutant. It was concluded that Aspergillus nidulans can be considered as an enzyme producer.

    Full Text Available Somatic recombination in heterozygous diploid cells may be a promotional agent of neoplasms by inducing homozygosity of defective genes. Tumor suppressor genes may in this way be completely suppressed in recombinant cells. In this work, the genotoxic effects of detergent derived from the castor oil plant (Ricinus communis in heterozygous diploid cells of Aspergillus nidulans are evaluated. Previous studies have evaluated the application of this substance in endodontic treatments as an irrigating solution. The recombinogenic potential of the compound has been studied through the production of homozygous cells for nutritional markers riboA1, pabaA124, biA1, methA17, and pyroA4. Detergent was diluted to 1:10, 1:20, and 1:40, and morphologic alterations, delay in conidiophore development, and mitotic recombination occurrence were reported for the three dilutions. Although past studies have demonstrated the antimicrobial action of the detergent under analysis, our results revealed its cytotoxic effects and recombinogenic potential.A recombinação somática em células diplóides heterozigotas pode atuar como agente promotor de neoplasias por induzir homozigose de genes deletéreos.

O presente trabalho avaliou a genotoxicidade do detergente derivado do óleo da semente da mamona (Ricinus communis em células diplóides heterozigotas do fungo filamentoso Aspergillus nidulans. Trabalhos anteriores avaliaram a aplicação dessa solução no tratamento de canais radiculares como líquido irrigador. O potencial recombinagênico desse composto foi estudado pela origem de células homozigotas para os marcadores nutricionais: riboA1, pabaA124, biA1, metA17 e piroA4. A solução, diluída em 1:40, 1:20 e 1:10, induziu alterações morfológicas e atraso no desenvolvimento dos conidióforos da linhagem UT448//UT196 e aumento nas freqüências de recombinação mitótica. Embora trabalhos anteriores relatem a atividade antimicrobiana da solução em estudo, nossos resultados evidenciam a citotoxicidade e o potencial recombinagênico dessa substância.

    Full Text Available La determinación de la composición corporal y la determinación de la distribución de la grasa corporal es cada vez más importante en la valoración clínica del paciente con síndrome metabólico. De la exploración clínica, el perímetro de cintura (pc es un parámetro de medida imprescindible por su relación, independiente del índice masa corporal (IMC, con el riesgo cardiovascular asociado a la obesidad y al síndrome metabólico. Sin embargo, desde el punto de vista clínico, el pc no distingue entre exceso de grasa subcutánea y perivisceral. El desarrollo de nuevas técnicas de imagen como la TAC o la RMN permite realizar medidas de superficie de grasa regional, la introducción de otras, como el DEXA (del inglés Dual Energy X-ruy absorptiometry, permite una valoración del volumen de la grasa abdominal. Últimamente la BIA (análisis de impedancia bioeléctrica segmentada octopular (tanita BC418 determina la composición corporal del tronco y extremidades, pudiendo hacer seguimiento con las diferentes modalidades terapéuticas empleadas. Tanto el aumento de área grasa como el volumen intraabdominal se correlacionan con diversos factores de riesgo asociados a la obesidad, incluso más que el pc, por lo que cada vez estas mediciones se realizan con más frecuencia en la práctica clínica.Determining body composition and body fat distribution has become increasingly important in the clinical assessment of patients with metabolic syndrome. Among the clinical measurements, waist circumference is of crudial importance because of its relationship ­ regardless of the BMI ­ with the cardiovascular risk associated with obesity and metabolic syndrome. However, from the clinical point of view, waist circumference does not distinguish between excess subcutaneous or perivisceral fat. With the advent of new imaging techniques such as CT and MRI, it is now possible to measure regional fat surface, and the use of DEXA enables the assessment of abdominal fat volumes. More recently, segmental octopular BIA (Tanita BC418 has allowed the determination of limb and trunk body composition, thus permitting follow-up of the various therapeutic modalities used. Increases in abdominal fat area as well as in intra-abdominal volume correlate with different risk factores associated with obesity, even more so that waist circumference, hence the greater frequency of use of these measurements in the clinic.

    In China, dust samplers were originally designed to collect 'total dust' for a short term during production, which is different from the widely adopted sampling strategy for dust. With the aim to provide the conversion factor from Chinese total dust to US and German respirable dust and to look at the influences on conversion factors from environment, production, and instruments, a comparative field study on the dust concentration measurements by different sampling methods was carried out in the same Chinese industries as in the 1989-1990 study and in some other factories. A supplemental experiment was also conducted in a wind tunnel. Dust concentration was measured with a parallel sampling strategy by using the following samplers: 10-mm nylon cyclone for US respirable dust (AR), FSP-Berufsgenossenschaftliches Institut für Arbeitssicherheit (BIA) cyclone for German respirable dust (GR), and samplers for Chinese total dust (CT). Totally, 1434 samples were collected (269 AR, 198 GR, and 967 CT), from which 429 matched sample pairs (249 pairs of AR/CT, 180 GR/CT) were available to calculate conversion ratios. Industry- and job-based conversion factors are presented in this study. The conversion factor of AR/CT was 0.38 for tungsten mines, 0.19 for copper/iron mines, 0.65 for tin mines, and 0.20 for pottery industry, while the factor of GR/CT was 0.69 for tungsten, 0.37 for copper/iron, and 0.52 for pottery. In the job category, AR/CT factors varied from 0.16 to 0.96 and GR/CT from 0.12 to 0.72. For the industries studied in 1988-1989, the AR/CT and GR/CT factors were 0.29 and 0.45, respectively. Both factors were definitely influenced by production, CT dust concentration, sample gain, and variation of dust concentration. Moreover, the respirable dust concentration by FSP-BIA was significantly higher than that by 10-mm cyclones, 63.27-73.10% more as showed also by the wind tunnel experiment. Meanwhile, the GR/CT ratio was significantly larger than the AR/CT in every industry or job with only few exceptions. The GR/CT estimates should be considered as independent ones. Following these results, there is a need to use 'ideal samplers' (consistent with the internationally accepted respirable fraction) in practice and to assess the existent samplers in order to homogenize the exposure data situation.

    Full Text Available Abstract Background While high protein diets have been shown to improve satiety and retention of lean body mass (LBM, this study was designed to determine effects of a protein-enriched meal replacement (MR on weight loss and LBM retention by comparison to an isocaloric carbohydrate-enriched MR within customized diet plans utilizing MR to achieve high protein or standard protein intakes. Methods Single blind, placebo-controlled, randomized outpatient weight loss trial in 100 obese men and women comparing two isocaloric meal plans utilizing a standard MR to which was added supplementary protein or carbohydrate powder. MR was used twice daily (one meal, one snack. One additional meal was included in the meal plan designed to achieve individualized protein intakes of either 1 2.2 g protein/kg of LBM per day [high protein diet (HP] or 2 1.1 g protein/kg LBM/day standard protein diet (SP. LBM was determined using bioelectrical impedance analysis (BIA. Body weight, body composition, and lipid profiles were measured at baseline and 12 weeks. Results Eighty-five subjects completed the study. Both HP and SP MR were well tolerated, with no adverse effects. There were no differences in weight loss at 12 weeks (-4.19 ± 0.5 kg for HP group and -3.72 ± 0.7 kg for SP group, p > 0.1. Subjects in the HP group lost significantly more fat weight than the SP group (HP = -1.65 ± 0.63 kg; SP = -0.64 ± 0.79 kg, P = 0.05 as estimated by BIA. There were no significant differences in lipids nor fasting blood glucose between groups, but within the HP group a significant decrease in cholesterol and LDL cholesterol was noted at 12 weeks. This was not seen in the SP group. Conclusion Higher protein MR within a higher protein diet resulted in similar overall weight loss as the standard protein MR plan over 12 weeks. However, there was significantly more fat loss in the HP group but no significant difference in lean body mass. In this trial, subject compliance with both the standard and protein-enriched MR strategy for weight loss may have obscured any effect of increased protein on weight loss demonstrated in prior weight loss studies using whole food diets.

Se midió la adiposidad por métodos antropométricos e impedancia bioeléctrica (IBE). Se identificó la relación entre el consumo de Ca y adiposidad mediante correlación simple; se realizaron modelos multivariados ajustados al consumo de energía, edad, sexo y menarquía. El promedio de edad fue de 13.5 ± 0.8 años. Se identificó correlación negativa entre el consumo de Ca y los indicadores antropométricos peso, pliegues cutáneos, índice de masa corporal, masa grasa y porcentaje de grasa (los dos últimos por IBE y solamente en mujeres). El análisis multivariado, que incluyó el consumo de energía, no demostró asociación entre el consumo de Ca y adiposidad. En conclusión, el consumo de Ca no se asocia a adiposidad en adolescentes; los modelos multivariados mostraron que el consumo total de energía y la menarquía son las variables que muestran mayor asociación con adiposidad en esta etapa de la vida. Abstract in english The purpose was to evaluate the association between calcium (Ca) intake and adiposity in adolescents. A cross-sectional study of 125 adolescents 12 to 16 years. Ca intake was evaluated by 24-hour recall dietary surveys and food frequency consumption. Adiposity was measured by anthropometric methods [...] and bioelectrical impedance (BIA). The association between Ca intake and adiposity was identified by simple correlation and multivariate models adjusted to energy consumption, age, sex and menarche. Mean age of adolescents was 13.5 ± 0.8 years. A negative correlation was identified between Ca intake and anthropometric indicators weight, skinfolds, body mass index, fat mass and percentage of fat (the latter two by BIA and only in women). Multivariate analysis, including energy consumption showed no association between Ca intake and adiposity. In conclusion, Ca consumption does not associate with adiposity in adolescents; multivariate models showed that energy intake and menarche are the variables that show a higher association with adiposity at this stage of life.

A large body of clinical trials propose PA as a useful prognostic marker in clinical conditions like liver cirrhosis and breast, colon, pancreatic and lung cancer; positive association between PA and survival was also observed in surgical and HIV infected patients. Several authors suggest that PA can be an important tool in the evaluation of the clinical result or of the progression of the disease, and it can even be superior to other nutritional, biochemical or anthropometric indicators.

    Full Text Available Body composition assessment is an important factor in weight management, exercise science and clinical health care. Bioelectrical impedance analysis (BIA is widely used method for estimating body composition. The purpose of this study was to evaluate segmental multi-frequency bioimpedance method (SMFBIA in body composition assessment with underwater weighing (UWW and whole body dual energy x-ray absorptiometry (DXA in healthy obese middle-aged male subjects. The measurements were carried out at the UKK Institute for Health Promotion Research in Tampere, Finland according to standard procedures of BIA, UWW and DXA. Fifty-eight (n=58 male subjects, aged 36-53 years, body mass index (BMI 24.9-40.7, were studied. Of them forty (n=40 underwent also DXA measurement. Fat mass (FM, fat-percentage (F% and fat free mass (FFM were the primary outcome variables. The mean whole body FM (±SD from UWW was 31.5 kg (±7.3. By DXA it was 29.9 kg (±8.1 and by SMFBIA it was 25.5 kg (±7.6, respectively. The Pearson correlation coefficients (r were 0.91 between UWW and SMFBIA, 0.94 between DXA and SMFBIA and 0.91 between UWW and DXA, respectively. The mean segmental FFM (±SD from DXA was 7.7 kg (±1.0 for arms, 41.7 kg (±4.6 for trunk and 21.9 kg (±2.2 for legs. By SMFBIA, it was 8.5 kg (±0.9, 31.7 kg (±2.5 and 20.3 kg (±1.6, respectively. Pearson correlation coefficients were 0.75 for arms, 0.72 for legs and 0.77 for trunk. This study demonstrates that SMFBIA is usefull method to evaluate fat mass (FM, fat free mass (FFM and fat percentage (F% from whole body. Moreover, SMFBIA is suitable method for assessing segmental distribution of fat free mass (FFM compared to whole body DXA. The results of this study indicate that the SMFBIA method may be particularly advantageous in large epidemiological studies as being a simple, rapid and inexpensive method for field use of whole body and segmental body composition assessment

    Full Text Available Background Out of eight commonly agreed Millennium Development Goals (MDG, six are related to the attainment of Universal Health Coverage (UHC throughout the globe. This universalization of health status suggests policies to narrow the gap in access and benefit sharing between different socially and economically underprivileged classes with that of the better placed ones and a consequent expansion of subsidized healthcare appears to be a common feature for most of the developing nations. The National Health Policy in India (2002 suggests expansion of market-based care for the affording class and subsidized care for the deserving class of the society. So, the benefit distribution of this limited public support in health sector is important to examine to study the welfare consequences of the policy. This paper examines the nature of utilizationto inpatient care by different socio-economic groups across regions and gender in West Bengal (WB, India. The benefit incidence of public subsidies across these socio-economic groups has also been verified for different types of services like medicines, diagnostics and professional care etc. Methods National Sample Survey Organization (NSSO has collected information on all hospitalized cases (60th round, 2004 with a recall period of 365 days from the sampled households through stratified random sampling technique. The data has been used to assess utilization of healthcare services during hospitalization and the distribution of public subsidies among the patients of different socio-economic background; a Benefit Incidence Analysis (BIA has also been carried out. Results Analysis shows that though the rate of utilization of public hospitals is quite high, other complementary services like medicine, doctor and diagnostic tests are mostly purchased from private market. This leads to high Out-of-Pocket (OOP expenditure. Moreover, BIA reveals that the public subsidies are mostly enjoyed by the relatively better placed patients, both socially and economically. The worse situation is observed for gender related inequality in access and benefit from public subsidies in the state. Conclusion Focused policies are required to ensure proper distribution of public subsidies to arrest high OOP expenditure. Drastic change in policy targeting is needed to secure equity without compromising efficiency.

    Full Text Available O estudo objetivou avaliar o gasto energético de repouso (GER de mulheres pós-menopausadas submetidas a programa de treinamento com pesos. Foram estudadas 30 mulheres (FSH > 40mIU/mL entre 45 e 70 anos, separadas em dois grupos (GT: treinamento, n = 15 e GC: controle, n = 15. Calculou-se o índice de massa corporal (kg/m² e por meio da impedância bioelétrica (BIA determinaram-se o percentual de gordura corporal e a massa muscular. O GER foi obtido por meio da calorimetria indireta (O2 e CO2 respiratórios e calculado pela equação de Weir. A mensuração ocorreu após 12 horas de jejum, durante 30 minutos sob temperatura e umidade controladas. O GT participou do programa de treinamento com pesos durante 16 semanas, na freqüência de três vezes por semana. Os dados analisados pelos testes t de Student, Mann-Whitney e ANOVA (p The study had as objective to evaluate the resting energy expenditure (REE of post-menopause women submitted to a training program with weights. Thirty women, age between 45 and 70 years (FSH > 40 mIUmL, separated in two groups (TG: training n = 15 and CG: control n = 15 were studied. The body mass index (kg/m² was calculated and the body fat percentage and the muscular mass were determined through bioelectric impedance (BIA. The REE was obtained through indirect calorimetry (respiratory O2 and CO2 and calculated by the Weir equation. The measurement occurred after 12 hours of fasting, during 30 minutes under controlled temperature and humidity. The TG participated of the training program with weights during 16 weeks, in the frequency of three times per week. The analyzed data by the t-Student, Mann-Whitney and ANOVA tests (p < 0.05 demonstrated that the TG had body mass increased in the 1.8 kg mean, muscular mass in 2.0 kg and the REE presented increase of 8.4% in relation to the CG. In conclusion, the training with weights increased muscular mass and REE. Therefore, this kind of exercise is recommended part of strategy to revert muscular and metabolic losses derived from aging and/or menopause.

    Full Text Available The excess of body fat is related to the worsening of blood biochemical markers, and is also correlated with increased morbimortality. It is suggested that the anthropometry is limited to evaluated body composition with different body mass index (BMI, kg/m2. Thus, our objective was to determine if the anthropometry was comparable to bioelectric impedance (BIA and if anthropometric body indexes were correlated to blood biochemical markers and resting energy expenditure. Women ranging weight from normality to obesity (age: 18-64 years, 36±11 years, body mass index, BMI=24 to 57 kg/m2, 31±6 volunteered to participate. Body composition and body indexes were evaluated by both anthropometry and BIA. Resting energy expenditure and blood samples were obtained in the fasting state in the morning. Four blood biochemical markers were correlated with weight, waist-to-hip ratio and the sum of eight skinfolds (P RESUMO O excesso de gordura corporal é relacionado à piora dos marcadores bioquímicos sangüíneos, se associando ao aumento da morbi/mortalidade. É sugerido que a antropometria é limitada para avaliar a composição corporal de diferentes índices de massas corporais (IMC, kg/m2. Portanto, os objetivos deste estudo foram comparar à antropometria a bioimpedância e também, se os índices corporais antropométricos eram correlacionados aos marcadores bioquímicos sanguíneos e ao gasto energético de repouso. Mulheres entre normalidade e obesidade (n=48; idade: 18 a 64 anos, 36±11 anos, média e desvio padrão; IMC=24 a 57, 31±6, foram voluntárias. A composição e índices corporais foram avaliados por antropometria e bioimpedância; o gasto energético de repouso (GER por calorimetria indireta em jejum, pela manhã, e coletadas amostras sangue. Quatro fatores bioquímicos de risco foram correlacionados (P<0,05 ao peso, ao índice abdômen/quadril e a soma de oito pregas cutâneas. Cinco fatores bioquímicos de risco foram correlacionados (P<0,05, ao IMC, à circunferência do abdômen e ao percentual de gordura. O peso, o percentual de gordura, o IMC e a massa corporal magra foram positivamente correlacionados ao GER (P<0,05. As massas magras estimadas por bioimpedância e por antropometria foram estatisticamente iguais. Em conclusão, os dados antropométricos indicam boa correlação com os marcadores bioquímicos sangüíneos. A taxa colesterol total/HDL teve correlação com todas as medidas antropométricas e a glicose com nenhuma. A antropometria é um método simples e barato e está bem correlacionada aos marcadores bioquímicos sanguíneos, ao gasto energético de repouso e a bioimpedância. A redução nestes fatores de risco, através da mudança de estilo de vida, permitem reduzir a mobidade e mortalidade.

No entanto, envolve dificuldades e controvérsias sobre a identificação do [...] melhor método de avaliação nutricional. OBJETIVO: Identificar um método que ofereça diagnóstico nutricional seguro e eficiente. MÉTODOS: Estudo transversal avaliou 129 pacientes com cirrose hepática. Foram realizadas medidas antropométricas, avaliação subjetiva global, dinamometria e bioimpedância elétrica. RESULTADOS: Através do ângulo de fase do método BIA, associações significativas com Child-Pugh (P = 0,008), faixa etária e sexo foram observadas. A curva ROC (receiver operator characteristic) foi realizada para determinar o melhor ponto de corte do ângulo de fase de pacientes cirróticos, servindo como um dos parâmetros de referência para a avaliação nutricional com bioimpedância neste estudo, considerando a classificação por pontuação Child-Pugh como o padrão de referência para as condições clínicas dos pacientes com cirrose. CONCLUSÕES: A avaliação por meio de bioimpedância elétrica apresentou correlação estatisticamente significativa com o escore de Child-Pugh. A identificação do ângulo de fase de 5,44º é o novo parâmetro sugerido para a classificação do estado nutricional de pacientes cirróticos. Abstract in english CONTEXT: Malnutrition in cirrhotic patients with end-stage disease is common, and the degree of nutritional debilitation can play an important role in the pathogenesis of complications and cause a negative impact on prognosis. However, it involves difficulties and controversies regarding the identif [...] ication of the best nutritional assessment method. OBJECTIVE: To identify a method that provides a safe and effective nutritional diagnosis. METHODS: Cross-sectional study with 129 cirrhotic patients. Anthropometric measurements, subjective global assessment, hand grip strength and bioelectrical impedance. RESULTS: Through phase angle of bioelectrical impedance analysis (BIA) method, significant associations with Child-Pugh (P = 0.008), age group and gender were observed. The ROC (receiver operator characteristic) curve was generated to determine the best cutoff point of the phase angle of cirrhotic patients, serving as one of the reference parameters for the nutritional assessment with bioimpedance in this study, considering the classification through Child-Pugh score as the reference standard for the clinical conditions of patients with cirrhosis. CONCLUSIONS: The assessment through bioelectrical impedance presented a statistically significant correlation with Child-Pugh score. The identification of phase angle of 5.44º is the new parameter suggested for the classification of the nutritional conditions of cirrhotic patients.
