    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 =300-500nm and have a high triplet-state energy of 1.67eV. A cyanophenyl substituent renders BPTI such a stro

    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.)

  5. Resistivity and phase in localized BIA

    Shiffman, C. A.; Aaron, R.; Amoss, V.; Therrien, J.; Coomler, K.

    1999-10-01

    We describe a system for highly reproducible non-invasive rf impedance measurements as a function of position along body segments such as the thigh. Results are reported for mainly healthy male and female subjects ranging in age from 19 to 65 and in body-mass index from 15 to 40. A principal conclusion is that the phase of the impedance falls monotonically with increasing distance from the knee, with average values substantially above what is found using standard, whole-body bioelectrical impedance analysis (BIA). To compensate for thigh shape, the data are further analysed using an anatomical model based on reasonable approximations for the distributions of muscle, fat and bone, yielding values of the effective resistivity for current flow parallel to the muscle fibres. The phase and resistivity results are discussed with reference to the whole-body BIA study of maintenance haemodialysis patients by Chertow et al, and in regard to possible physiological correlations observed in this work.

    One-dimensional supramolecular columnar phases composed of porphyrins (electron donor: D) and benzo[ghi]perylenetriimides (electron acceptor: A) through triple hydrogen bonds have been successfully constructed to perform sequential light-harvesting and electron-transfer processes. A series of benzo[ghi]peryleneimide derivatives have been synthesized to examine the substituent effects such as imide and nitrile groups on the spectroscopic and electrochemical properties. Then, formation of the 1:1 supramolecular complex between zinc porphyrin and benzo[ghi]perylenetriimide derivatives through triple hydrogen bonds was confirmed by Job's plot of (1) H NMR titration. Next, the one-dimensional supramolecular nanoarrays were successfully prepared in a mixed solvent. X-ray diffraction (XRD) measurement suggested that these nanoarrays contained one-dimensional columnar phases composed of stacked donor and acceptor layers. Finally, femtosecond transient absorption and electron spin resonance (ESR) measurements clearly indicated that photoinduced electron transfer occurred via the singlet excited states in the supramolecular columns.

  19. Synthesis, microsome-mediated metabolism, and identification of major metabolites of environmental pollutant naphtho(8,1,2-ghi)chrysene

    Energy Technology Data Exchange (ETDEWEB)

    Sharma, A.K.; Gowdahalli, K.; Gimbor, M.; Amin, S. [Penn State College of Medicine, Hershey, PA (United States)

    2008-05-15

    Naphtho(8,1,2-ghi)chrysene, commonly known as naphtho(1,2-e)pyrene (N(1,2-e)P) is a widespread environmental pollutant, identified in coal tar extract, air borne particulate matter, marine sediment, cigarette smoke condensate, and vehicle exhaust. Herein, we determined the ability of rat liver microsomes to metabolize N(1,2-e)P and an unequivocal assignment of the metabolites by comparing them with independently,synthesized standards. We developed the synthesis of both the fjord region and the K-region dihydrodiols and various phenolic derivatives for metabolite identification. In summary, N(1,2-e)P trans-11, 12-dihydrodiol was the major metabolite formed along with N(1,2-e)P 4,5-trtins-dihydrodiol and 12-OH-N(1,2-e)P on exposure of rat liver microsomes to N(1,2-e)P. The presence of N(1,2-e)P in the environment and formation of fjord region dihydrodiol 14 as a major metabolite in in vitro metabolism studies strongly suggest the role of N(1,2-e)P as a potential health hazard.

  6. Common pipistrelle (Pipistrellus pipistrellus Schreber, 1774 in the bat fauna of the Białowieża Primeval Forest

    Directory of Open Access Journals (Sweden)

    Rachwald Alek

    2015-06-01

    Full Text Available The occurrence of the Common pipistrelle in the bat fauna of the Białowieża Primeval Forest was expected, because the taxon P. pipistrellus was previously comprised of two separate species. Earlier observations of P. pipistrellus in the Białowieża area can mostly be counted for by the new species Soprano pipistrelle, which is considered equally widely distributed in the area. In this study, we were able to record and distinguish several passes of the Common pipistrelle by means of bat detecting techniques. Bats were found in two locations, the first one being the Białowieża village, whereas the second one is the woodland in close proximity of the Czerlonka village. It is very likely, that this species is more widely distributed in the Białowieża area, especially in the vicinity of human settlements.

  7. Morphotectonic control of the Białka drainage basin (Central Carpathians): Insights from DEM and morphometric analysis.

    Wołosiewicz, Bartosz

    2016-06-01

    The Białka river valley is directly related to a deep NNW-SSE oriented fault zone. According to the results of previous morphometric analyses, the Białka drainage basin is one of the most tectonically active zones in the Central Carpathians. It is also located within an area of high seismic activity. In this study Digital Elevation Model (DEM) based, morphometric analyses were used to investigate the morphotectonic conditions of the watershed. The results reveal the relationships between the main tectonic feature and the landforms within the research area. The lineaments, as obtained from the classified aspect map, seem to coincide with the orientation of the main structures as well as the trends revealed by the theoretical Riedel-Skempton shear model. Base-level and isolong maps support the conclusion that the Białka and Biały Dunajec fault zones exert a strong influence on the morphology of the adjacent area.

    2013-04-01

    A bioimpedance device (BIA) for evaluation of sarcopenia - age related muscle mass loss - is designed, developed and evaluated. The requirements were based on lightweight design, flexible and user enabled incorporation of measurement protocols and WiFi protocol for remote device control, full internet integration and fast development and usage of measurement protocols. The current design is based on usage of a microcontroller with integrated AD/DA converters. The prototype system was assembled and the operation and connectivity to different handheld devices and laptop computers was successfully tested. The designed BIA device can be accessed using TCP sockets and once the connection is established the data transfer runs successfully at the specified speed. The accuracy of currently developed prototype is about 5% for the impedance modulus and 5 deg. for the phase for the frequencies below 20 kHz with an unfiltered excitation signal and no additional amplifiers employed.

    2016-08-01

    Bioelectrical impedance analysis (BIA) is a noninvasive and commonly used method for the assessment of body composition including body water. We designed a small, portable and wireless multi-frequency impedance spectrometer based on the 12 bit impedance network analyzer AD5933 and a precision wide-band constant current source for tetrapolar whole body impedance measurements. The impedance spectrometer communicates via Bluetooth with mobile devices (smart phone or tablet computer) that provide user interface for patient management and data visualization. The export of patient measurement results into a clinical research database facilitates the aggregation of bioelectrical impedance analysis and biolectrical impedance vector analysis (BIVA) data across multiple subjects and/or studies. The performance of the spectrometer was evaluated using a passive tissue equivalent circuit model as well as a comparison of body composition changes assessed with bioelectrical impedance and dual-energy X-ray absorptiometry (DXA) in healthy volunteers. Our results show an absolute error of 1% for resistance and 5% for reactance measurements in the frequency range of 3 kHz to 150 kHz. A linear regression of BIA and DXA fat mass estimations showed a strong correlation (r(2)=0.985) between measures with a maximum absolute error of 6.5%. The simplicity of BIA measurements, a cost effective design and the simple visual representation of impedance data enables patients to compare and determine body composition during the time course of a specific treatment plan in a clinical or home environment.

It produces benzylisoquinoline alkaloids (BIA) including the narcotic analgesic morphine, the muscle relaxant papaverine, and the anti-cancer agent noscapine. Though BIAs play crucial roles in many biological mechanisms their steps in biosynthesis and the responsible genes remain to be revealed. In this study, expressions of 3-hydroxy-N-methylcoclaurine 4′–methyltransferase (4′OMT) and reticuline 7-O-methyltransferase (7OMT) genes were subjected to manipulation to functionally characterize their roles in BIA biosynthesis. Measurements of alkaloid accumulation were performed in leaf, stem, and capsule tissues accordingly. Suppression of 4′OMT expression caused reduction in the total alkaloid content in stem tissue whereas total alkaloid content was significantly induced in the capsule. Silencing of the 7OMT gene also caused repression in total alkaloid content in the stem. On the other hand, over-expression of 4′OMT and 7OMT resulted in higher morphine accumulation in the stem but suppressed amount in the capsule. Moreover, differential expression in several BIA synthesis genes (CNMT, TYDC, 6OMT, SAT, COR, 4′OMT, and 7OMT) were observed upon manipulation of 4′OMT and 7OMT expression. Upon silencing and overexpression applications, tissue specific effects of these genes were identified. Manipulation of 4′OMT and 7OMT genes caused differentiated accumulation of BIAs including morphine and noscapine in capsule and stem tissues. PMID:26909086

Moreover, differential expression in several BIA synthesis genes (CNMT, TYDC, 6OMT, SAT, COR, 4´OMT and 7OMT were observed upon manipulation of 4´OMT and 7OMT expression. Upon silencing and overexpression applications, tissue specific effects of these genes were identified. Manipulation of 4´OMT and 7OMT genes caused differentiated accumulation of BIAs including morphine and noscapine in capsule and stem tissues.

    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.

    2016-09-01

    Full Text Available This paper focuses on the market segmentation of recreational forest services using the concept of ‘sensation seeking’ for describing recreational expectations of town dwellers. The physical activity of town dwellers from the urban agglomeration of Białystok and the Knyszyn Forest (North-Eastern Poland during outdoor recreation was analysed using this concept. The results of this research suggest that less than thirty percent of inhabitants of the Białystok agglomeration tend to be physically active during outdoor recreation. This is evidence of a low level of physical culture within the part of the society analysed in this study. Amongst all participants, only seven percent use the Knyszyn Forest for recreational purposes based on physical activity. The limited interest in active recreation in forests that we observed can be attributed to two main causes: 1 the lack of acceptance of a closed forest landscape as a recreational area; 2 the lack of recreational facilities in the Knyszyn Forest that would encourage healthy behaviour during active outdoor recreation.

    Full Text Available The tibial plateau leveling osteotomy (TPLO is a relatively new and innovative surgical treatment for the cranial cruciate ligament rupture in the canine species. The real intent of the procedure is to provide functional stability to the stifle joint by eliminating or neutralizing the cranial tibial thrust during weight bearing instead to restore the cranial cruciate ligament function. The proposal of this study is to report a review of the TPLO procedure, emphasizing procedure, surgical technique, post operative care and complications. The TPLO procedure consists in a radial osteotomy in the tibial plato and rotation of the caudal plateau in order to obtain a desired angle. After the leveling of the tibial plateau, a bone plate and screws are used to stabilize the osteotomy until bone is healed up. The complications that have been associated with the procedure include tibial tuberosity fracture and patellar tendon tendinosis. This procedure has become increasingly more popular for surgical treatment of cranial cruciate ligament injuries in large breed dog. The long term clinical results have not been completely elucidated yet. It has been showed that this technique doesn’t halt the degenerative joint disease.A osteotomia do platô da tíbia (TPLO é um tratamento relativamente novo e inovador para a ruptura do ligamento cruzado cranial (RLCC na espécie canina. Ao invés de restaurar a função do ligamento, o procedimento promove estabilidade funcional para a articulação do joelho, por eliminar ou neutralizar a força tibial cranial durante a sustentação de peso. A proposta do presente estudo é revisar a técnica de TPLO, enfatizando o procedimento, técnica cirúrgica, cuidados pós-operatórios e complicações. A técnica da TPLO consiste na realização de uma osteotomia circular do platô da tíbia com rotação de sua porção caudal até a obtenção do ângulo desejado.

    An automated biomolecular interaction analysis instrument (BIAcore) based on surface plasmon resonance (SPR) has been used to determine human immunoglobulin G (IgG) in real time. Polyclonal anti-human IgG antibody was covalently immobilized to a carboxymethyldextran-modified gold film surface. The samples of human IgG prepared in HBS buffer were poured over the immobilized surface. The signal amplification antibody was applied to amplify the response signal. After each measurement, the surface was regenerated with 0.1 mol/L H3PO4. The assay was rapid, requiring only 30 min for antibody immobilization and 20 min for each subsequent process of immune binding, antibody amplification and regeneration. The antibody immobilized surface had good response to human IgG in the range of 0.12-60 nmol/L with a detection limit of 60 pmoL/L. The same antibody immobilized surface could be used for more than 110 cycles of binding, amplificafion and regeneration. The results demonstrate that the sensitivity, specificity and reproducibility of amplified immunoassay using real-time BIA technology are satisfactory.

    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 (α obese, the problematic of SO will be found earlier in life.

It is particularly significant in preschool age, when the need for movement is predominant. Psychomotor development, conditioned by children's innate abilities and their own activity, depends upon the influence of external surroundings as well as parental upbringing and preschool education. The aim of the study was to obtain data regarding physical activity (both structured and unstructured of children during their stay in a kindergarten. Material and methods. The study was conducted in five state kindergartens situated in four main housing estates of Bia³a Podlaska. It included 11 groups of older preschool children. It was a diagnostic study. A diagnostic poll method employed in the study included interviews with teachers, lesson observations (during one day and document analyses (programmes and class registers. Results. During their stay in a kindergarten children take part in physical activities for 1.5 hours a day. During this period they participate in obligatory forms of physical activity such as morning gymnastics, movement plays, outdoor activities and gymnastic exercises. Furthermore, optional movement activities are organised in kindergartens (different forms in different kindergartens. Such extra classes enable children to be physically active for over two more hours per week. Conclusions. In terms of caring about health and motor development of children, not all elements of preschool education programmes are fully realised. Training sessions, workshops and lectures showing diverse forms of physical activity for children ought to be organised for preschool teachers.

    The development of mining and metallurgic industries of Pb and Zn ores in the Biała Przemsza catchment area has had a strong influence on the condition of the surface water and bottom sediments. In the following study, total contents of metals and metalloids were researched in the water and bottom sediment samples from the Biała Przemsza River. The samples were collected monthly in 2014 at five sampling points along the river. The research helped to determine correlations between the parameters and components of the water environment (metals/metalloids, cations/anions, pH, Eh, conductivity, carbon (TOC, IC, TC), and suspension). The contents of metals and metalloids were determined with inductively coupled plasma-mass spectrometry (ICP-MS), whereas anions and cations were investigated with ion chromatography (IC). The simplified Community Bureau of Reference (BCR) three-step sequential chemical extraction was performed on Biała Przemsza River bottom sediments collected in April, July, and October. At its lower course, the Biała Przemsza River water did not meet the Polish surface water quality standards. The Biała Przemsza River water is mainly loaded with metals. Toxic concentrations of Cd, Pb, and Zn were observed at sampling points in Okradzionów and Sławków. The toxic Tl concentration was exceeded (2-6 μg/L) at three sampling points. The Biała Przemsza River bottom sediments were composed mostly of medium and fine sand. The BCR extraction of the bottom sediments demonstrated that Cd and Zn were bound to cations/anions and carbonates loosely adsorbed on the bottom sediments in spring and summer. Such a situation was observed at all the sampling points, except for BP3 in Okradzionów. The organic carbon concentration increased along the river course.

    Full Text Available O presente artigo trata sobre uma questão inserida na atual tensão do mundo árabe no norte da África, o caso da Líbia. As potências ocidentais acusam o líder da Líbia Muamar Kadafi de crimes contra a humanidade e atacam em uma coalizão representada pela OTAN. Meses antes essas mesmas potências realizavam negócios com o líder líbio que doravante é o mau a ser combatido. Essa pode ser mais uma guerra pelo petróleo, mas agora inserida numa região que vive um colapso político de origem muito diversa do que ocorre na Líbia. Na verdade o que vem ocorrendo na Líbia é uma guerra civil e não uma rebelião popular e o principal objetivo desta guerra é o petróleo. A medida que as forças de Trípoli foram adquirindo armas das potências ocidentais essa guerra ficou desigual e afetou os interesses das multinacionais do petróleo instaladas na região

    This paper reviews various bioimpedance methods permitting to measure non-invasively, extracellular, intracellular and total body water (TBW) and compares BIA methods based on empirical equations of the wrist-ankle resistance or impedance at 50 kHz, height and weight with BIS methods which rely on an electrical model of tissues and resistances measured at zero and infinite frequencies. In order to compare these methods, impedance measurements were made with a multifrequency Xitron 4200 impedance meter on 57 healthy subjects which had undergone simultaneously a Dual X-ray absorptiometry examination (DXA), in order to estimate their TBW from their fat-free-mass. Extracellular (ECW) and TBW volumes were calculated for these subjects using the original BIS method and modifications of Matthie[Matthie JR.

    Full Text Available BACKGROUND: Propionibacterium freudenreichii is essential as a ripening culture in Swiss-type cheeses and is also considered for its probiotic use. This species exhibits slow growth, low nutritional requirements, and hardiness in many habitats. It belongs to the taxonomic group of dairy propionibacteria, in contrast to the cutaneous species P. acnes. The genome of the type strain, P. freudenreichii subsp. shermanii CIRM-BIA1 (CIP 103027(T, was sequenced with an 11-fold coverage. METHODOLOGY/PRINCIPAL FINDINGS: The circular chromosome of 2.7 Mb of the CIRM-BIA1 strain has a GC-content of 67% and contains 22 different insertion sequences (3.5% of the genome in base pairs. Using a proteomic approach, 490 of the 2439 predicted proteins were confirmed. The annotation revealed the genetic basis for the hardiness of P. freudenreichii, as the bacterium possesses a complete enzymatic arsenal for de novo biosynthesis of aminoacids and vitamins (except panthotenate and biotin as well as sequences involved in metabolism of various carbon sources, immunity against phages, duplicated chaperone genes and, interestingly, genes involved in the management of polyphosphate, glycogen and trehalose storage. The complete biosynthesis pathway for a bifidogenic compound is described, as well as a high number of surface proteins involved in interactions with the host and present in other probiotic bacteria. By comparative genomics, no pathogenicity factors found in P. acnes or in other pathogenic microbial species were identified in P. freudenreichii, which is consistent with the Generally Recognized As Safe and Qualified Presumption of Safety status of P. freudenreichii. Various pathways for formation of cheese flavor compounds were identified: the Wood-Werkman cycle for propionic acid formation, amino acid degradation pathways resulting in the formation of volatile branched chain fatty acids, and esterases involved in the formation of free fatty acids and esters

    The coastline in the Jastrzębia 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 Jastrzębia 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

    Full Text Available Elements of the Belarusian language in the Russian dialect used by the Old Believers living in the Suwałki-Augustów region The 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 Suwałki-Augustów region in the north-eastern Poland. They inhabit mostly two villages in the county of Suwałki, namely Gabowe Grądy and Bór, which are very close to each other, and three towns: Augustów, Suwałki 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.   Białoruskie elementy językowe w rosyjskiej gwarze staroobrzędowców mieszkających w regionie suwalsko-augustowskim Artykuł poświęcony jest problematyce białoruskich elementów językowych w rosyjskiej gwarze staroobrzędowców mieszkających w Polsce.

    Full Text Available Este artigo representa uma tentativa de compreensão do impacto das mudanças ocorridas, e ainda em curso, na Líbia após as manifestações da Primavera Árabe que resultaram na queda do regime autoritário e na implantação de mecanismos democráticos de governo, considerando as questões internas e externas e a crescente interdependência dos diferentes fatores político-econômicos sobre a sociedade líbia em sua transformação. Depois de uma série de ações desastrosas do governo de Khadafi, no âmbito local e internacional, os protestos levaram a sociedade a uma intervenção bélica direta sobre o governo e sobre o Estado. O impacto das intervenções estadunidenses nesta mudança é proeminente, devido às características peculiares ligadas à posição desta potência de um lado, e sua relação tensa com a Líbia de outro. Este trabalho apresenta alguns aspectos da problemática decorrente da contradição ideológica entre Secularismo e Islamismo Político no que diz respeito à participação no novo Estado e aos princípios da governança. Esta temática adquiriu uma importância acentuada nos atuais debates intelectuais e políticos no Mundo Árabe. Agora, mais do que nunca, a solução democrática representa o pressuposto conciliatório entre as duas correntes antagônicas, cujo confronto descolou-se do estágio de discurso teórico para o nível da luta armada.

    Full Text Available The last 25 years have been in many Polish cities a period of intensive modernization and renewals of the existing public spaces. Most of all the resurfacing of the pavement and changing of street furniture have been held. In many cases, the transformations in the urban areas were integrated with exclusion from traffic. The question arises what criteria architects or landscape architects follow and what design solutions apply. It is also interesting how the new shape of the floor in public spaces (understood here as a pavement and street furniture together can help to create integrating and activating space for residents. And how it can affect the quality of life in a wider area. This article attempts to answer these questions based on new solutions on Kosciuszko Square in Białystok, executed in 2005-2009.

    Occurrence of professional dysphonia was analysed in a group of 309 patients treated in the Phoniatric Outpatient Clinic, Department of Otolaryngology, Medical Academy in Białystok through the period of 1999-2001. In a group of professional voice users female teachers of primary schools and lower secondary schools predominated. Obtained results were compared with those from a group of 65 persons of other occupations. In the both groups other harmful factors affecting the voice organ were excluded. The clinical assessment included subjective and objective laryngological examination using videolaryngostroboscopy. The clinical material was evaluated in a view of functional and organic disorders of the voice organ. Early occurrence and aggravation of functional changes in the larynx was recorded in non professional voice users in the course of their seniority. In professional patients organic changes were more common and occurred earlier than functional disorders. Severity of dysphonia was related to the larynx pathology, especially of a functional character.

    Full Text Available Propionibacterium freudenreichii is used as a ripening culture in Swiss cheese manufacture. It grows when cheeses are ripened in a warm room (about 24°C. Cheeses with an acceptable eye formation level are transferred to a cold room (about 4°C, inducing a marked slowdown of propionic fermentation, but P. freudenreichii remains active in the cold. To investigate the P. freudenreichii strategies of adaptation and survival in the cold, we performed the first global gene expression profile for this species. The time-course transcriptomic response of P. freudenreichii CIRM-BIA1(T strain was analyzed at five times of incubation, during growth at 30°C then for 9 days at 4°C, under conditions preventing nutrient starvation. Gene expression was also confirmed by RT-qPCR for 28 genes. In addition, proteomic experiments were carried out and the main metabolites were quantified. Microarray analysis revealed that 565 genes (25% of the protein-coding sequences of P. freudenreichii genome were differentially expressed during transition from 30°C to 4°C (P1. At 4°C, a general slowing down was observed for genes implicated in the cell machinery. On the contrary, P. freudenreichii CIRM-BIA1(T strain over-expressed genes involved in lactate, alanine and serine conversion to pyruvate, in gluconeogenesis, and in glycogen synthesis. Interestingly, the expression of different genes involved in the formation of important cheese flavor compounds, remained unchanged at 4°C. This could explain the contribution of P. freudenreichii to cheese ripening even in the cold. In conclusion, P. freudenreichii remains metabolically active at 4°C and induces pathways to maintain its long-term survival.

    Full Text Available As fraturas da diáfise da tíbia nas crianças e adolescentes são lesões relativamente comuns e geralmente têm boa evolução com os métodos clássicos de tratamento conservador. Sua elevada frequência se deve ao alto grau de exposição da criança nas suas atividades físicas e também pela anatomia e topografia da tíbia, expondo-a ao trauma direto ou indireto. Algumas particularidades devem ser consideradas e respeitadas na sua abordagem, que compreendem aspectos atinentes à faixa etária, local de acometimento (se proximal ou distal, tipo de fratura e de terapêutica instituída. A vantagem anatômica do periósteo mais espesso e a relativa flexibilidade na acomodação de impactos angulares podem proporcionar na criança de menor idade, maior estabilidade e consequente tendência ao melhor prognóstico. Nas crianças maiores e nos adolescentes o grau de exposição a traumas de maior energia, a maior gravidade e complexidade das lesões têm tornado mais comum a estabilização cirúrgica. Complicações encontradas nessas fraturas nos adultos como infecção, retarde de consolidação e pseudartrose são muito menos frequentes nas crianças, mas o risco de instalação de síndromes compartimentais é uma eventualidade que requer atenção, principalmente nas condutas incruentas com imobilizações gessadas.Tibial diaphyseal fractures in children and adolescents are relatively common injuries and often evolve with good results when treated through traditional methods of conservative treatment. Their elevated frequency is due to the high degree of exposure of children in physical activities and also to the topographic location, exposing them to direct or indirect trauma. The approach used should consider and respect some features regarding age, place of affection (whether proximal or distal, type of fracture and therapy. The anatomical advantage of a thicker periosteum and flexibility when submitted to angular impacts can provide

    Studies of fungi and fungus- like organisms in the northeastern Poland have mainly concentrated on running waters in the vicinity of Białystok, 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

    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 Białowieża 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.

    Full Text Available Utilizando-se biodigestores contínuos, abastecidos com dejetos de bovinos leiteiros e operados sob três tempos de retenção hidráulica, avaliou-se o efeito do processo de digestão anaeróbia sobre o número de microrganismos indicadores de poluição fecal, sobre a ocorrência de ovos e larvas de helmintos parasitas de ruminantes, analisando-se também os teores de sólidos totais e voláteis do afluente e dos efluentes, bem como a produção e a qualidade do biogás produzido. Verificou-se que vinte dias de retenção hidráulica foram suficientes para reduzir significativamente o número de microorganismos indicadores de poluição fecal e a quantidade de ovos de helmintos parasitas de ruminantes. Os resultados obtidos nas análises de sólidos totais e voláteis, bem como a produção de biogás (m³/dia, permitem concluir que o biodigestor modelo Chinês operado com 20 dias de tempo de retenção hidráulica, apresentou mais eficiência. Vale ressaltar que vinte dias de retenção foram insuficientes para impedir a sobrevivência de larvas de helmintos parasitas de ruminantes.

    Full Text Available A fratura Salter Harris tipo II ocorre comumente na epífise proximal de tíbia em potros e tem reparação difícil mas com o advento das técnicas de fixação interna, o prognóstico tem melhorado. No caso descrito, em um potro da raça árabe de 26 dias de idade, com fratura proximal de tíbia direita tipo Salter Harris II, foram utilizadas as placas de compressão para garantirem estabilização e aproximação dos fragmentos fraturados, porém com risco de ocasionar distúrbios no desenvolvimento esquelético. No caso relatado, através do controle radiológico, não foi evidenciada diminuição da radioluscência na região correspondente à cartilagem de conjugação proximal da tíbia. O artigo tem como objetivo discutir o tratamento empregado que se mostrou como alternativa viável pelo resultado favorável com bons resultados.The most frequent fracture is tibia’s proximal epiphysis in foals is Salter Harris type II although its difficult to repair. The development of the inner fixation technique has been made the prognosis better. The dynamic compression bone plate allow guaranteed reduction and stabilization of the bone’s fragments, but it can promote development disturbs. In this case, by the radiological control, it has not shown less radiolucency in the proximal tibia’s growth plate. The treatment used showed itself as a feasible alternative because of the favourable good results.

    This study aimed to set up current reference charts of anthropometric data in the Saarland. Only national and international data were available to be compared but no former Saarland charts could be found. In the period between 1994 and 1995 we investigated children of 3 to 11 years in a cross-sectional study. Therefore we measured body height, weight, circumferences, skinfolds and bioelectrical impedance (BIA). No significant gender differences were found for body height and weight. Boys of all groups of age showed bigger abdominal circumferences than girls of the same age. On the other hand upper-arm and calf-girth of younger girls were larger than that from boys. In higher age groups circumferences become rather equal. The skinfolds of Saarland girls are thicker than those of boys. The urban rural comparison indicated no significant differences. Nor was any social divergence found among the aforementioned parameters. Regarding height Saarland children are seen to be similar or somewhat shorter than those examined in national or international studies. By the way, in higher percentiles the children in our study were heavier. Thus high BMI values of our study are bigger compared with former studies. According to the definition of obesity by the ECOG almost 20 to 30% of our children are obese. The older children become the higher is the percentage of obesity. Comparing girls and boys, bioelectrical impedance shows higher values for girls. In higher age classes resistance levels gets smaller, in boys more so than in girls. Body fat estimated by a formula based on BIA test parameters yielded negative values. So we propose the use of sex- and age-specific raw charts of BIA test parameters.

Adicionaram-se a estes, lodos de estação de tratamento de efluentes, provenientes de um curtume (LC e de uma universidade (LU. A digestão anaeróbia gera biogás, rico em metano, e pode ser uma alternativa para o tratamento de resíduos. O objetivo deste estudo foi avaliar o volume e a fração molar do biogás gerado a partir da adição de diferentes lodos aos inóculos. As combinações foram dispostas em frascos de vidro vedados, a 35°C, o ensaio foi mantido enquanto ocorreu geração de gás. O volume de biogás foi determinado utilizando o método volumétrico, a fração molar foi determinada por cromatografia gasosa. Os teores de carbono orgânico e sólidos totais (ST foram determinados antes e depois dos ensaios de digestão anaeróbia. Verificou-se que a amostra de arroz com a adição do LU apresentou o maior volume de gás gerado (132 mL/g ST. A mesma amostra de lodo apresentou a maior fração molar de metano, aproximadamente, 0,76 e gerou em torno de 40 mL de biogás. A combinação do LU e do resíduo de arroz gerou fração molar de hidrogênio de em torno de 0,35. Houve redução dos teores de carbono orgânico e ST em todas as combinações analisadas. O processo de digestão anaeróbia é uma alternativa promissora para a co-digestão dos resíduos avaliados.

    The purpose of this thesis has been to evaluate tourism appeal of the commune of Janów Podlaski, as compared to the other communes in the administrative district of Biała Podlaska, and to analyse the recreational potential of the natural environment within the commune and it's present day infrastructure for tourism industry. For evaluation of the tourism attractiveness of the commune, based on comparative analysis, the method of synthetic measures was applied. The commune of Janów Podlaski belongs to one of the most attractive areas for tourists in the administrative district of Biała Podlaska. The attractiveness of the commune is associated with the Bug river, which flows across high-value landscapes and possess many ecological assets. Development of water tourism, however, is hindered by the fact that the Bug forms part of Poland's state border and it's water is rather polluted. Walking tourism in the commune of Janów Podlaski is encouraged owing to a well-developed and properly sing-posted networks of trails. The accommodation facilities are not evenly distributed as most of the rooms for tourists can be found in Janów Podlaski.

Os parâmetros avaliados foram produção e potencial de produção de biogás, reduções de sólidos totais (ST, fibra em detergente neutro (FDN e fibra em detergente ácido (FDA. A produção de biogás e potencial de produção apresentaram efeito quadrático nos TRH de 17 e 24 dias, evidenciando como doses ideais 4,09 e 5,63% de glicerina bruta, respectivamente, para produção e 4,52 e 5,42% de glicerina bruta para potencial de produção. Não houve diferença entre as doses de glicerina bruta dentro do TRH de 10 dias para as reduções de ST. No entanto, foi observado diferença entre as doses nos TRH 17 e 24, com a maior redução observada de 54,9% ao incluir 5% de glicerina bruta no maior TRH. As reduções de FDN e FDA aumentaram de acordo com a adição de glicerina bruta nos TRHs de 10 e 17 dias. A inclusão de 4 a 6% de glicerina bruta no TRH 24 mostrou-se mais eficiente na produção de biogás e reduções de ST e FDN. Já visando maior redução de FDA pode-se utilizar doses mais altas de glicerina a partir da co-digestão com dejetos suínos.

Entretanto, pouco se conhece a respeito do perfil enzimático desses microrganismos. Nesse contexto, a presente investigação propõe avaliar a produção de enzimas hidrolíticas extracelulares por isolados de rizóbia nativos da Amazônia Central. Essa triagem constitui o primeiro passo na seleção de microrganismos nativos que são potencialmente exploráveis como produtores de enzimas. Foram testados 67 isolados nativos de rizóbia para as atividades amilolítica, celulolítica, lactolítica, lipolítica, pectinolítica e proteolítica, em meio YMA modificado. A atividade ureolítica foi detectada em meio ágar-uréia. As bactérias isoladas dos nódulos de feijão caupi mostraram maior capacidade em produzir enzimas do que os isolados bacterianos de soja. De todas as enzimas hidrolíticas avaliadas, apenas a pectinase não foi detectada neste estudo. Amilase (32,8%, protease (28,4%, urease (20,9% e carboximetilcelulase (9,0% foram as enzimas mais freqüentes produzidas pelos isolados.

    Full Text Available OBJETIVOS: Determinar a microbiota bacteriana aeróbia da conjuntiva de doadores de córnea e seu padrão de suscetibilidade a antibióticos; verificar o número de córneas utilizadas para transplante e a média de tempo de preservação em solução preservante com gentamicina e estreptomicina; traçar o perfil dos doadores e receptores de córnea. MÉTODOS: Espécimes clínicos foram colhidos de saco inferior da conjuntiva de ambos os olhos, de 40 doadores de córnea. As amostras foram inoculadas em ágar sangue azida, ágar chocolate e ágar MacConkey e o antibiograma foi realizado pelo método de Kirby-Bauer. RESULTADOS: A freqüência de cultura positiva da conjuntiva de doadores de córnea foi de 72,5%, sendo que Gram-positivos totalizaram 81,6% e apenas 18,4% das amostras foram identificadas como Gram-negativos. Vancomicina inibiu 100% dos Gram-positivos, ao passo que a sensibilidade dos Gram-negativos à gentamicina foi de 53,8% e à estreptomicina foi de 30%. O sexo masculino predominou entre os doadores e receptores, a média de tempo entre o óbito e a enucleação foi de 2h e a de preservação em solução preservante com gentamicina e estreptomicina foi de 7 dias. Neoplasia e mais de uma causa associada foram as causas de óbito mais freqüentes. O ceratocone foi a principal indicação para transplante (51,7%. CONCLUSÕES: Staphylococcus coagulase negativo foi o microrganismo com o maior número de isolamentos, apresentando sensibilidade variada aos antimicrobianos. A quantidade de córneas utilizadas para transplante foi bastante inferior em relação ao total de captações. O perfil dos doadores e receptores de córnea mostrou-se heterogêneo para grande parte das variáveis analisadas.PURPOSE: To determine aerobic bacterial microbiota of the conjunctiva of cornea donors and its patterns of susceptibility to antibiotics; verify the number of corneas used for transplant and the average time of preservation in solutions with

    Full Text Available RESUMO O uso de regimes de corte em estádio vegetativo para os cereais de inverno é interessante quando se busca intensificar a produção de alimento volumoso para ruminantes. No entanto, é necessário se averiguar o impacto desse manejo sobre as características das silagens resultantes. Dessa forma, o objetivo do experimento foi avaliar o valor nutricional e a estabilidade aeróbia de silagens de cereais de inverno, submetidas a regimes de corte no estádio vegetativo, prévio ao corte para ensilagem. Os cereais utilizados foram trigo (Triticum aestivum cv. BRS Gralha Azul, cevada (Hordeum vulgare cv. BRS Brau, aveia-branca (Avena sativa cv. URS Guará, aveia- preta (Avena strigosa cv. Embrapa 139 e triticale (X Triticosecale cv. IPR 11, associados a três regimes de corte: sem cortes prévios (silagem exclusiva; um corte; e com dois cortes em estádio vegetativo e subsequente produção de silagem. Na avaliação nutricional, a cevada apresentou valores baixos de FDA (311,7 e 375,3g kg de MS-1 e altos de NDT (569,2 e 533,4g kg de MS-1 para os sistemas com um e dois cortes, respectivamente. Na avaliação da estabilidade aeróbia, os materiais foram bastante estáveis após a abertura dos silos, com exceção da aveia-branca e da aveia-preta, no regime sem cortes. As silagens de triticale e de cevada apresentaram as maiores estabilidades nutricionais com o aumento no número de cortes.

    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.

    Full Text Available O objetivo do presente trabalho é apresentar os resultados iniciais, obtidos com a osteotomia valgizante de adição de tíbia, fixada com placa calço descrita por Puddu. Foram operados 29 joelhos em 27 pacientes para correção de geno-varo, sendo que, em apenas um paciente o procedimento bilateral teve objetivo profilático. O seguimento foi de 3 a 28 meses com média de 14 meses. A osteotomia proximal de tíbia foi feita de forma oblíqua iniciando na inserção distal do ligamento colateral medial em direção ao tubérculo de Gerdy. A osteotomia foi aberta e fixada com uma placa calço de Puddu. O espaço aberto da osteotomia foi preenchido por enxerto autólogo de ilíaco. A carga total era dada com 45 dias de pós-operatório. Os resultados obtidos mostraram que entre 4 a 6 meses os pacientes tiveram uma significativa melhora na sintomatologia indutora do procedimento cirúrgico. A avaliação final mostrou 27 resultados satisfatórios e apenas 2 regulares. Como conclusão essa técnica tornou a osteotomia de tíbia um procedimento reprodutível com resultados previsíveis com excelente manutenção no pós-operatorio da correção obtida no trans-operatório.The objective of this paper is to present the initial results obtained with the valgus tibial osteotomy, fixed with the wedge plate described by Puddu.

O experimento foi conduzido em delineamento inteiramente casualizado com três repetições, em esquema de parcelas subdivididas no tempo, de modo que os tratamentos (silagens sem inoculantes e com inoculante experimental e comercial foram aleatorizados nas parcelas e os tempos de avaliação aeróbia das silagens (0, 2, 8 ou 10 dias após a abertura dos silos nas subparcelas. Após 90 dias de armazenamento, os silos foram abertos e amostras de aproximadamente 2,5 kg foram retiradas para avaliação da estabilidade aeróbia com base na temperatura de cada amostra. As mudanças químicas e microbiológicas foram avaliadas. Após abertura dos silos, verificou-se aumento nas populações de bactérias do ácido lático, leveduras e fungos filamentosos. Houve aumento nos valores de pH resultante da redução da concentração dos ácidos orgnicos e de aumentos dos teores de matéria seca e proteína bruta. A adição de L. buchneri às silagens melhorou sua estabilidade, enquanto a silagem sem inoculante apresentou estabilidade de 55 horas. As silagens inoculadas não ultrapassaram essa temperatura limite em um período de 10 dias. A melhoria da estabilidade foi ocasionada pela associação de altas concentrações de cido acético ao ácido propiônico e pela menor concentração de ácido lático no momento de abertura, o que inibiu a proliferação de fungos filamentosos e leveduras após abertura dos silos.This study aimed to evaluate the effect of the addition of two L. buchneri strains on the aerobic stability of the Mombaça grass silages. The experiment was carried out in a completely randomized design with three replicates in split-plot in time scheme, so that the treatments (silages without inoculant and with experimental or commercial inoculants were randomized on plot and in times of aerobic

A espécie forrageira foi colhida aos 60 dias de crescimento vegetativo. O delineamento experimental utilizado foi o inteiramente casualizado com quatro repetições, utilizando-se o modelo de medidas repetidas no tempo. Os tratamentos constituíram-se de quatro densidades (100, 120, 140 e 160 kg MS/m³. As alterações químicas das silagens foram determinadas com 0, 3 e 6 dias após a abertura. As leituras das temperaturas das silagens foram obtidas em intervalos de 12 horas, 156 horas após a acomodação dos baldes na câmara climática, utilizando-se o termômetro inserido a 10 cm no centro da massa de silagem. As silagens de maiores valores de densidade alcançaram máxima temperatura em maior tempo que as densidades inferiores, evidenciando a maior estabilidade decorrente de melhor compactação da massa ensilada. Com o avançar do tempo de exposição aeróbia, as silagens tiveram aumento nos valores de pH e decréscimos nos teores de nitrogênio amoniacal (N-NH3. Verificou-se queda nos teores de NIDN (nitrogênio insolúvel em detergente neutro e da fração B3 com o aumento da densidade, o que caracterizou a participação dessa fração durante o processo de proteólise após a quebra da vedação. Os teores de fibras em detergente neutro e detergente ácido durante a exposição ao ar sofreram acréscimo, sendo os maiores valores obtidos nas silagens de menor densidade. As silagens mais densas apresentaram maiores coeficientes de digestibilidade verdadeira in vitro que os demais tratamentos.This trial aimed to evaluate the aerobic stability of marandu grass silages submitted to different packing intensities. The forage was harvested at 60 days of regrowth. The following packing densities were evaluated: 100, 120, 140, and 160 kg DM/m³. Silage chemical changes were determined 0, 3, and 6 days after air

    Full Text Available O presente estudo teve por finalidade estimar a potência aeróbia em atletas com LME praticantes de RCR, correlacionar os níveis de VO2máx com a classificação funcional (CF dos atletas e analisar o comportamento da FC antes e pós-teste. A amostra foi composta por 10 atletas com LME, do sexo masculino e idade média de 29,6±6,5anos. Os atletas foram submetidos ao teste de corrida de 12 minutos e monitorados com o frequêncimetro cardíaco. A média do VO2máx foi de 18,3±8,1ml(kg.min-1 e da FCmáx de 114,6±25,3bpm. Os valores de VO2máx obtidos no estudo são classificados como médio para a população com tetraplegia. Observou-se que existe correlação moderada (r=0,77 entre a CF e o VO2máx entre atletas praticantes de RCR e por fim, observou-se baixos valores de FC frente á um teste submáximo, fato que pode estar relacionado à diminuição da atuação simpática após LME.

    Full Text Available A síndrome metabólica (SM é definida pela presença de, ao menos três, dentre cinco fatores de risco cardiovascular: hiperglicemia, resistência à insulina, obesidade, dislipidemia e pressão arterial elevada. Embora portadores de SM apresentem baixa aptidão física e pior qualidade de vida (QV, quando comparado aos indivíduos sem SM, ainda não foram investigadas as correlações entre a aptidão física e a QV em mulheres com SM. O objetivo do presente estudo foi comparar a QV, força muscular e aptdião aeróbia, bem como analisar a correlação entre a QV e a aptidão física de mulheres com e sem SM. Participaram do estudo 49 mulheres, 21 com SM (33.5 ± 9.1 anos e 28 sem SM (32.3 ± 7.9 anos. Para avaliação da QV, aptidão aeróbia e força muscular foram utilizados, respectivamente, o questionário Short Form Health Survey 36 (SF-36, o teste de caminhada de 6 minutos (6-C e o teste de preensão manual. As mulheres com SM apresentaram pior QV, percorreram menor distância no 6-C e obtiveram menor força muscular relativa. Foi observada correlação positiva entre a aptidão aeróbia e quatro domínios da QV: capacidade funcional, limitação por aspectos físicos, dor e aspectos sociais da funcionalidade. Mulheres com SM apresentam menor de força muscular e aptidão aeróbia, bem como piores escores de QV no estado de saúde geral, capacidade funcional, dor no corpo, limitação por aspectos emocionais, aspectos sociais da funcionalidade e limitação por aspectos físicos quando comparado com mulheres sem SM.

    Full Text Available INTRODUÇÃO: Os efeitos dos esteroides anabolizantes (EA sobre a massa muscular e força são controversos e dependentes do treinamento realizado e das fibras musculares recrutadas. Com isso, o objetivo deste estudo foi avaliar os efeitos da associação de EA ao treinamento de força ou aeróbio sobre a hipertrofia e força muscular. MÉTODOS: Ratos Wistar (42 foram divididos em seis grupos: sedentário (SC, n = 7, sedentário anabolizante (SA, n = 7, treinado natação controle (TNC, n = 7, treinado natação anabolizante (TNA, n = 7, treinado força controle (TFC, n = 7 e treinado força anabolizante (TFA, n = 7. O EA foi administrado duas vezes por semana (10mg/kg/semana. Os protocolos de treinamento foram realizados durante 10 semanas, cinco sessões semanais. Foram avaliadas a hipertrofia dos músculos sóleo, plantar e gastrocnêmio (massa muscular corrigida pelo comprimento da tíbia, a proteína total muscular (Bradford e a força muscular em patas traseiras (testes de resistência à inclinação. RESULTADOS: Não foram observadas diferenças significantes na hipertrofia do músculo sóleo. Os grupos TFC e TFA apresentaram, respectivamente, hipertrofia de 18% e 31% no músculo plantar comparado ao grupo SC. A hipertrofia foi 13% maior no grupo TFA em relação ao grupo TFC. Resultados semelhantes foram encontrados no músculo gastrocnêmio. Os grupos TFC e TFA apresentaram significantes aumentos na quantidade total de proteína nos músculos plantares, sendo essa mais pronunciada no grupo TFA e positivamente correlaciona a hipertrofia muscular. Observamos aumento de força nas patas traseiras nos grupos TCF e TAF. CONCLUSÃO: A administração de EA ou sua associação ao treinamento aeróbio não aumenta a massa muscular e força. Porém, à associação ao treinamento de força leva a maior hipertrofia muscular em fibras glicolíticas. Portanto, o tipo de treinamento físico, recrutamento muscular e características das fibras

    Full Text Available As complicações das artroplastias totais do joelho relacionadas com o próprio material são muito raras, exceto o desgaste do polietileno. Neste artigo os autores reportam o caso de uma paciente do sexo feminino de 58 anos referenciada ao pronto-socorro do nosso hospital por uma fratura periprotética tibial (tipo I da classificação da Mayo Clinic. Uma observação mais cuidadosa mostrou a presença concomitante da referida fratura da tíbia associada à fratura de fadiga da haste tibial. A prótese com a haste foi remetida a um laboratório de biomecânica independente onde foi avaliada e efetuada uma reconstrução com uso de sistema de elementos finitos em CAD de modo a verificar a existência de algum defeito de fabricação e as eventuais causas para o sucedido. Depois de avaliadas diversas hipóteses, concluiu-se que a fratura do material foi provocada por uma sobrecarga na zona de transição prato/haste secundária à falência óssea prévia (fratura. Da avaliação do caso ressalta-se novamente a necessidade de efetuar uma avaliação adequada da mineralização óssea e, em caso de dúvida, utilizar uma haste longa.Total knee arthroplasty complications related to the prosthetic material are very rare, except for polyethylene wear. We report the case of a 58-year-old woman who came to the emergency service of our hospital with a periprosthetic tibial fracture (Mayo Clinic type I. Careful examination showed that this fracture was concomitantly associated with a tibial stem fatigue fracture. The prosthesis and the stem were sent to an independent biomechanics laboratory for evaluation. A finite-element CAD system was used to make a reconstruction, so as to ascertain whether there had been any manufacturing defect and what the causes of the event might have been. After evaluation of several hypotheses, it was concluded that the fracture in the prosthetic material had been caused by overloading at the plate/stem transition zone

    Full Text Available OBJECTIVE: To compare the locked, unreamed intramedullary nail with Ender pins in the treatment of open Gustilo grade I or II or closed tibial diaphyseal fractures of type A, B, or C2 of the AO classification. MATERIALS AND METHODS: Forty-four patients with unilateral tibial diaphyseal fractures were treated with intramedullary nails or Ender pins. Twenty patients were treated with an unreamed intramedullary nail with access via the patellar tendon with static locking. Twenty-four patients were treated with Ender pins introduced medially and laterally with respect to the tuberosity of the tibia. The main parameters analyzed were type of reduction, complications, union rate, deformities, joint mobility, pain, gait, effort capacity, presence of neurovascular disorders, and complaints related to the synthesis material. RESULTS: During 1 year of follow-up, the fractures of 90.0% of the patients with intramedullary nails and 95.7% of patients with Ender pins healed within an average of 21.5 weeks and 20.9 weeks, respectively. The significant findings were as follows: patients treated with Ender pins had less mobility of the subtalar joint; patients treated with intramedullary nails were more likely to have pain in the knee; both groups showed shortening of the tibia at the end of 1 year of treatment. CONCLUSIONS: The two methods are similar in the treatment of type A, B, and C2 tibial diaphyseal fractures.OBJETIVO: Comparar a haste intramedular bloqueada não-fresada com os pinos de Ender no tratamento das fraturas da diáfise da tíbia tipos A, B ou C2 da classificação AO, fechadas ou expostas graus I ou II de Gustilo.

    Full Text Available The increase of the ethanol production in Brazil leads to growing of vinasse (main by-product of sugar and alcohol industry, worsing the problem related to its destinantion. Vinasse is rich in nutrients and has a high content of organic matter, which justifies its intense ferti-irrigation use in sugar cane crop areas. Thus, the anaerobic digestion of vinasse by UASB (upflow anaerobic sludge blanket digestion reactor emerges as an alternative treatment for this by-product, showing also an economic factor, the production of methane and its use. This work aimed to implement the system of anaerobic digestion of vinasse in UASB reactor and the use of energy generated by biogas. In this way, the design of UASB was based on organic volumetrical load of vinasse. The estimation of the baseline was based on the mass balance between the carbon present in the vinasse and CO2 emitted by the aerobic degradation of effluent into the environment. From the compute emissions, it was found that emissions from the baseline and the project implementation would be the same, and additionally it could be occur the production of electricity by biogas. In this way, biogas produced by anaerobic digestion has a competitive energy potential compared to other energy sources and presents additionality; however, carbon credits marked could not be a financial attractive in the development of this type of project.A crescente produção de etanol no Brasil acarretou aumento na produção de vinhaça (principal subproduto da indústria sucroalcoleira, agravando o problema de sua destinação.

    Full Text Available Utilization of sugarcane Saccharum officinarum L. silage is increasing in Brazil but intensive ethanol production during fermentation reduces forage quality. This experiment aimed to evaluate the effects of additives on fermentation and aerobic stability of sugarcane silages produced in minisilos. Treatments were (fresh basis: untreated silage (control, urea (5.0 g kg-1, sodium benzoate (1.0 g kg-1, potassium sorbate (0.3 g kg-1, Lactobacillus plantarum (1 x 10(6 cfu g-1, and Lactobacillus buchneri (3.64 x 10(5 cfu g-1. At the 94th day after ensilage, ethanol concentration was lower in urea, benzoate, sorbate and L. buchneri supplemented silages and higher in L. plantarum inoculated silage, as compared to control. Urea and benzoate treated silages showed the highest and L. plantarum treated silage the lowest in vitro dry matter digestibility. Effluent production was higher in the urea treated silage. Inoculation with L. buchneri reduced 50% ethanol production as compared to control. Urea and L. buchneri reduced yeast count. Aerobic stability was enhanced by L. buchneri and benzoate. Sodium benzoate and L. buchneri were the most promising additives, improving both silage fermentation and aerobic stability; inoculants containing L. plantarum can be deleterious to fermentation and conservation of sugarcane silages.A utilização de silagem de cana-de-açúcar (Saccharum officinarum L. está aumentando no Brasil, mas a intensa produção de etanol durante a fermentação reduz a qualidade da forragem.

    Full Text Available Ruptura de ligamento cruzado cranial (RLCCr é a afecção ortopédica mais frequente no joelho de cães e a sutura fabelo-tibial é frequentemente utilizada na sua correção. Essa técnica pode estar associada com complicações incisionais, lesão tardia de menisco, edema associado ao material de sutura e infecção. O objetivo desta nota foi relatar a ocorrência de fratura proximal de tíbia em um cão, causada por complicação em sutura fabelo-tibial para correção de RLCCr. Um canino atendido em outro serviço foi submetido à osteossíntese com placa 2,0mm para correção de complicação em técnica extra-capsular, na qual houve fratura da tíbia na região do orifício criado para confecção da sutura fabelo-tibial. Houve falha dos implantes e a placa foi removida. A fratura foi estabilizada com fixador esquelético externo circular, sendo constatada, após 120 dias, consolidação.Cranial cruciate ligament rupture (CCLR is one of the most common orthopedic diseases in dogs and extracapsular suture with nylon is often used for its correction. This technique may be associated with incisional complications, post-surgical meniscus injury, swelling associated with suture material and infection. The objective of this study is to report a tibial fracture in a dog, caused by complications after an extracapsular suture for the repair of CCLR. An adult dog, which suffered a tibial fracture after an extracapsular fixation for a CCLR, underwent surgery for the fixation of the fracture with a 2.0mm plate, by a referring veterinarian, but the implant failed. The plate was removed and the fracture was stabilized with a circular fixator. Bone consolidation was observed after 120 days.

    Full Text Available This study aims to identify opportunities for improving the environmental performance of the power generation technologies from the treatment of municipal solid waste - MSW using the tool of the life cycle assessment. The most significant impact was the disposal of waste in landfill; while incineration itself was the technology in which the impacts were most prevalent. The results of the comparative analysis, point out the need to improve the environmental performance of the incineration process, as this was more impactful, considering also that the incineration process has greater energy efficiency. It was observed that are necessary investments in technologies that enable the reduction of these impacts, so that incineration is a possible solution for sustainable treatment of MSW associated with power generation, for its efficiency on power generation, and for the reduction of volume, mass and hazardous waste. Therefore, it recommends the use of energy recovery technologies such as incineration, anaerobic digestion and utilization of landfill biogas, associated with recycling to generate electricity from MSW treatment. = O presente trabalho tem por objetivo identificar as oportunidades para melhoria do desempenho ambiental dos processos de geração de energia pela biodigestão anaeróbia e incineração a partir do tratamento de resíduo sólido urbano - RSU com o uso da ferramenta avaliação do ciclo de vida.

Após protocolo anestésico e cirúrgico habituais, foi provocado um defeito ósseo na diáfise proximal das tíbias esquerda e direita, sendo implantada a HAP-91 apenas na tíbia direita. Os animais, dois de cada vez, foram sacrificados aos 8, 30, 60 e 120 dias após a cirurgia, quando foram obtidas amostras do local da lesão, que foram fixadas, lavadas, polimerizadas, cortadas e submetidas a dupla coloração em solução aquosa de acetato de uranila a 1% e em solução de citrato de chumbo. Essas secções foram avaliadas e fotografadas ao microscópio eletrônico de transmissão. Os componentes tissulares na tíbia tratada e na controle foram similares. A absorção da HAP-91 caracterizou-se pela presença de células multinucleadas na interface entre HAP-91 e osso, morfologicamente consideradas como osteoclastos. Ainda, encontraram-se grânulos de HAP-91 no interior de células morfologicamente caracterizadas como macrófagos. A absorção celular de grânulos de HAP-91, concomitante com a formação adjacente de osso novo, sugere que a osteointegração da HAP-91 seja análoga ao processo normal de reabsorção-aposição óssea.With the objective of studying the synthetic hydroxyapatite (HAP-91 as a bone substitute, eight healthy mongrel adult dogs were used.

Doze horas após a fratura, foi iniciado tratamento anticoagulante, mantido por 28 dias. Via subcutânea, um grupo recebeu heparina sódica na dose de 200UI/Kg de 12 em 12 horas, enquanto outro, recebeu enoxaparina na dose de 1mg/Kg de 12 em 12 horas, doses preconizadas para tratamento do tromboembolismo em humanos. O terceiro grupo, controle, recebeu água destilada. Durante o experimento, os animais foram avaliados clinicamente e após 28 dias, sacrificados. Nos animais dos três grupos, a evolução clínica foi semelhante. Mediante análise anatomopatológica efetuada por estudo descritivo e quantitativo, foi observada presença de fibrose, cartilagem e osso igualmente nos três grupos, sempre com predomínio de tecido ósseo. O estudo biomecânico, realizado por intermédio de ensaios de flexão, demonstrou coeficiente de rigidez e carga máxima semelhantes nos três grupos. Nenhuma diferença clínica, anatomopatológica e biomecânica foi encontrada, resultando todas as fraturas em consolidação de acordo com os critérios adotados, concluindo-se, portanto, que a heparina sódica e a enoxaparina nas doses, via e tempo de administração utilizados não interfiriram na consolidação da fratura da tíbia do rato.An experimental study in rats was accomplished to evaluate the effect of anticoagulant on fracture union, according to clinical, anatomopathological, and biomechanical approaches.

    Full Text Available A importância das bactérias conhecidas como rizóbia no estabelecimento de leguminosas tem sido amplamente reconhecida. Porém, poucas são as informações referentes ao perfil enzimático dessas bactérias benéficas. O estudo objetivou investigar a influência do pH do meio sólido sobre a atividade enzimática de rizóbios nativos da Amazônia Central. Essa triagem constitui o primeiro passo no processo de seleção de microorganismos benéficos, como produtores de enzimas de aplicação biotecnológica. Nesse estudo, 64 isolados de rizóbia foram testados para a produção extracelular de amilase, lipase, pectinase e protease, em meio YMA modificado. Excetuando a atividade pectinolítica, todas as outras enzimas (amilase, lipase e protease foram detectadas nos isolados investigados. Dois isolados (INPA R-975 e INPA R-926 exibiram atividades amilolíticas, lipolíticas e proteolíticas. Os índices enzimáticos amilolíticos e proteolíticos variaram significativamente entre os isolados e as condições de pH do meio de cultura. De maneira geral, as maiores atividades amilolíticas e proteolíticas foram exibidas pelos isolados INPA R-957, INPA R-915B e INPA R-991 em pH 6,5. O isolado INPA R-957 também se mostrou amilolítico e proteolítico nos pHs 5,0 e 8,0. Esse estudo mostrou que alguns rizóbios nativos da Amazônia representam fontes promissoras de amilase e protease de uso biotecnológico, sobretudo na tecnologia de alimentos.The importance of rhizobia bacteria in the establishment of legume plants has been widely recognized. However, information is scarce regarding the enzymatic profiles of these beneficial bacteria. The objective of this study was to investigate the influence of pH of solid medium on enzymatic activity of native Central Amazonian rhizobia strains.

    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.   Польский язык в Республике Беларусь Положение польского национального меньшинства в РБ всегда была трудной, так как политика властей была направлена на уничтожение всего, что имело польские корни и было связано с польской культурой: интеллигенции, школ, театров, газет. В связи с этим возрождение образования на польском языке в конце 80-тых годов прошлого столетия начиналось с нулевого уровня и наибольшее количество учащихся изучало польский язык в конце 90-тых годов XX века. В последние годы наблюдается уменьшение количества учащихся, что объясняется демографической и современной политической ситуацией. На формирование национального самосознания наиболее значительное влияние оказывает cемья. К сожалению, большинство современных польских семей не выполняет эту функцию, использование польского языка как языка внутрисемейных отношений уменьшается. Польский язык в костеле также выходит из употребления, понятие “католик” сегодня уже не означает “поляк”. Как видно из исследований, 66% католиков хотели бы, чтобы литургия в костелах была на польском языке, 20% – на белорусском, 10% – на польском и русском, 4% – ином языке. Такая ситуация создает опасность исчезновения польского языка из литургии и катехизиса. В связи с вышесказанным усиливается роль польских школ и польских общественных объединений в воспитании и обучении детей и молодежи. Oбучение и воспитание детей польскому языку начинается уже в детском саду в кружках либо в специальных группах с обучением и воспитанием на польском языке. В школах обучение польскому языку ведется в разных формах. Наибольшее количество желающих учится во внеурочное время, определенная часть – в классах с обязательным изучением польского языка. Помимо этого в Гродненской области существуют две школы с обучением на польском языке. В высших учебных заведениях Беларуси также изучается польский язык, а в Гродненском госуниверситете с 1989 г. cуществует кафедра полонистики, занимающаяся подготовкой учителей польского языка. Дальнейшее развитие польскоязычного образования в РБ зависит как от позиции поляков, так и от современной политической ситуации в нашей стране.

    Full Text Available Forage silage is the main form of voluminous food storage in the world. The ensiling makes possible the palatable food supply during the whole year, mainly in the drought period. During the ensiling process, the green forage inside of the silo suffers many transformations until the complete stabilization of the mass, acquiring the silage characteristics. With the objective of improving the fermentation process, some farmers have been using inoculants. However, the use of these inoculants, without evaluation of silage nutritional quality can increase the material cost. Besides, a big importance has been spared to the silage preservation process and your aerobics stability, mainly during the period of your use. Several works showing controversial results were found, in the literature, although some researches have shown beneficial effects of inoculants use on silage preservation and quality. It can be concluded that the inoculants use should not be considered as substitute of ensiling appropriate handling, such as: crop, compactation, storage and closure. In silages appropriately prepared, the inoculants use presents little or any benefit on silage preservation and quality.A silagem de forrageiras é a principal forma de armazenamento de alimento volumoso no mundo. A ensilagem possibilita o fornecimento de alimento palatável durante todo o ano, principalmente no período de seca. Durante o processo de ensilagem, a forragem verde colocada no silo sofre transformação até a estabilização completa da massa, adquirindo as características de silagem. No intuito de melhorar o processo de fermentação, têm-se utilizado alguns inoculantes. Porém, a utilização destes, sem avaliação da qualidade nutricional da silagem pode aumentar o custo do material ensilado. Além disso, importância crescente tem sido dispensada ao processo de preservação das silagens e a sua estabilidade aeróbia, sobretudo durante o período de sua utilização. Embora

Created defects in right tibias were filled in group I with omentum, in group II with PLLA nanofiber scaffold and in group III with combination of the omentum and PLLA. The same defects were created in left tibia of all groups but did not receive any treatment (control group. Histological and histomorphometric evaluations were performed at two, four and six weeks after the implantation. RESULTS: Histological changes on all groups along with the time course were scored and statistical analysis showed that the average scores in group III were significantly higher than the other groups. CONCLUSION: Histomorphometric analysis of bone healing was shown to be significantly improved by the combined PLLA with omentum compared with the other groups, suggesting this biomaterial promote the healing of cortical bone, presumably by acting as an osteoconductive scaffold.OBJETIVO: Investigar as propriedades de osteocondução e desempenho biológico do ácido L láctico-Poly (PLLA com omento em defeitos ósseos.

    Full Text Available The effects of treatment with anaerobic cecal microflora (ACM and/or lactose and/or acetic acid on systemic and digestive tract of broiler chicks infection with Salmonella Typhimurium and S. Enteritidis were studied. ACM was used without previous bacterial identification. Treatment with ACM contributed to the resistance of broiler chicks to infection with Salmonella spp. The infections were more persistent in the cecum, rectum and crops in decreasing order of intensity. The infections were also self-limiting since treated and control lots presented similar infection rates at the end of the experiments. Alone or in combination with lactose, ACM reduced the colonization of the digestive tract of broiler chicks by S. Typhimurium and S. Enteritidis. The effect of the combination of ACM with lactose or acetic acid was not potentiated in terms of reduction of fecal excretion of Salmonella spp. Treatment with ACM reduced the amount of S. Typhimurium and S. Enteritidis in the feces. Alone or in combination with lactose, ACM reduced the cecal pH in treated birds. S. Enteritidis was much more invasive than S. Typhimurium and the use of ACM alone was more effective on the reduction of systemic infection. An explanation for the process of prevention of intestinal colonization with Salmonella spp. probably resides in the interrelationship of physiological, microbiological and immunological phenomena, as well as the variation in cecal pH.Estudaram-se os efeitos do tratamento de frangos com microbiota cecal anaeróbia (MCA isolada ou associada à lactose ou ao ácido acético, sobre a infecção sistêmica e do trato digestivo de aves por Salmonella Typhimurium e S.

Alguns trabalhos experimentais investigaram sua ação no processo de consolidação de fraturas, por meio de estudos clínicos e histológicos, sendo escassas as análises biomecânicas. Nesse estudo foram utilizados 20 ratos da linhagem Wistar, divididos aleatoriamente em dois grupos iguais: grupo A (controle e grupo B (tratado com diclofenaco sódico. Em ambos os grupos foram realizadas fraturas abertas, após perfuração, na tíbia direita. A administração da droga foi via intramuscular, dose única diária, por 28 dias. Os animais foram pesados semanalmente. Após o sacrifício as tíbias foram dissecadas, pesadas e submetidas a ensaio biomecânico de flexão analisando-se carga máxima, deformação e coeficiente de rigidez. Observou-se que no grupo tratado com AINH não houve aumento do peso corpóreo a partir da segunda semana e as tíbias fraturadas foram mais pesadas. Neste grupo o calo ósseo suportou menor carga máxima, apresentando maior deformação e menor coeficiente de rigidez. Nos animais tratados, o osso não fraturado também se mostrou menos rígido. Concluiu-se, nas condições estudadas, que o DS alterou o processo de consolidação e o metabolismo ósseo, levando a retardo na maturação do calo e menor rigidez do osso intacto, respectivamente.The antinflammatories are agents utilized on clinical practice that interfere on inflammatory process by synthesis inhibition of prostaglandin and tromboxanes.

    Full Text Available ResumoA avaliação da microbiologia anaeróbia é um método caro e muito difícil. Técnicas simples são disponíveis para avaliação de microrganismos de diversos usos como médico, alimentar, ambiental e sistemas anaeróbios para tratamento de efluentes. Uma metodologia desenvolvida foi usada para avaliar a atividade de grupos de microrganismos em digestão anaeróbia com possível aplicação a substratos específicos. A técnica usa gases isentos de oxigênio em frascos tipo penicilina e fechados com tampa de borracha e selo de alumínio, onde foi adicionado um indicador de redução, complementos nutricionais e agentes redutores após a esterilização. O metabolismo dos microrganismos foi observado nesses frascos fechados depois de um período de incubação de quatorze dias pela variação da turbidez, de pH medido em indicador de Arrhenius e de gás capturado em tubos Duran. A técnica do Número Mais Provável (NMP foi usada para contagem de microrganismos em meio de cultivo adaptado para grupos específicos de microrganismos que eram esperados para se desenvolver em água residuária de mandioca com amido e seus hidrolisados (dextrina, maltose e glicose como fonte de energia. Para aferir o método, amostras foram coletadas de um reator acidogênico de mistura completa ligado a um reator metanogênico de leito fixo, ambos alimentados com água residuária de mandioca. O gás capturado nos tubos Duran dos frascos de penicilina foi analisado por cromatografia quanto ao conteúdo de metano. O uso dos meios permitiu separar os microrganismos em três grupos usando meio de cultivo seletivo: Meio Mínimo (MM sem substratos orgânicos, Meio Completo (MC com uma mistura de amido de mandioca e seus hidrolisados e Meio Diferencial (MD usando cada derivado de amido isoladamente. O sistema de tratamento anaeróbio no período analisado operou com um bom desempenho e a microbiologia confirmou estes resultados. No efluente do reator acidog

    Full Text Available CONTEXTUALIZAÇÃO: Recursos eletrofísicos, como o ultrassom (US e a terapia laser de baixa potência (LLLT, vêm sendo cada vez mais utilizados na prática fisioterapêutica. Estudos sugerem que esses recursos são capazes de estimular a proliferação de osteoblastos e a osteogênese no local da fratura, promovendo maior deposição de massa óssea e acelerando o processo de consolidação. OBJETIVO: Analisar os efeitos do US e da LLLT no processo de consolidação óssea por meio das análises biomecânica e histológica do calo ósseo. MÉTODOS: Foram utilizados 30 ratos machos, distribuídos aleatoriamente em três grupos: grupo controle fratura, sem tratamento (GC; grupo fratura tratado com US pulsado com burst de 1,5 MHz, 200us, 1KHz, 30 mW/cm² (GUS e grupo fratura tratado com laser 830nm, 100mW, 120J/cm² (GL. Foram realizados defeitos ósseos circulares com broca de 2 mm de diâmetro nas tíbias dos animais. Os tratamentos foram realizados a cada 48 horas, totalizando sete aplicações e, no 14º dia, os animais foram sacrificados. A tíbia direita foi designada para análise biomecânica, enquanto a esquerda, para análise histológica. RESULTADOS: A análise biomecânica não mostrou diferença estatisticamente significativa entre as propriedades biomecânicas do GC, GL e GUS. Na análise morfométrica, tanto GUS quanto GL apresentaram área de osso neoformado estatisticamente maior em relação ao GC. No entanto, quando as duas modalidades de tratamento foram comparadas, não foram encontradas diferenças estatísticas entre elas. CONCLUSÃO: Ambos os recursos utilizados neste estudo foram capazes de acelerar o processo de reparo ósseo em ratos.BACKGROUND: Electrophysical agents such as Ultrasound (US and low-level laser therapy (LLLT have been increasingly used in physical therapy practice.

    Full Text Available Reading Snyder. Reflections of a Belarusian historian Timothy Snyder has carried out a detailed comparison of mass extermination practices of two different though similar regimes. His comparison indicates basic resemblances as well as a large number of discrepancies. At the same time, the conclusions drawn by the author of Bloodlands challenge numerous commonly accepted theses from the field of political history. However, it is easy for a historian from Belarus to notice some inaccuracies regarding the “Belarusian theme.” Timothy Snyder is not familiar with the most important works of Belarusian historiography, which refer to the question of the monograph directly (the works by Jerzy Turonek, Eugeniusz Mironowicz, Igor Kuzniecow and others. Whereas Snyder’s approach to the “Polish theme” lacks some criticism. Nevertheless, Snyder’s book offers quite a comprehensive analysis of the history of mass extermination. Bloodlands demonstrates that the main victim of these murders was Human: death annihilates all national and cultural differences, whereas the most important is the human aspect of the tragedy suffered by the millions, which should not be regarded as statistics.

    Full Text Available INTRODUÇÃO: O exercício aeróbio é recomendado para o tratamento da hipertensão. Sua intensidade pode ser prescrita com base na porcentagem da frequência cardíaca máxima (%FCmáx ou no consumo pico de oxigênio (%VO2pico em que os limiares ventilatórios (LV são alcançados. Entretanto, alguns hipertensos que iniciam o treinamento podem estar tomando betabloqueadores, o que pode influenciar esses parâmetros. OBJETIVO: verificar os efeitos do atenolol sobre os LV de hipertensos sedentários. MÉTODOS: Nove voluntários realizaram dois testes ergoespirométricos máximos após quatro semanas de tratamento com atenolol (25 mg administrado por via oral duas vezes por dia e com placebo, administrados em ordem fixa e de forma cega. Durante os testes, a frequência cardíaca (FC, a pressão arterial (PA e o VO2 no repouso, limiar anaeróbio (LA, ponto de compensação respiratória (PCR e pico do esforço foram analisados. RESULTADOS: O VO2 aumentou progressivamente no exercício e seus valores foram semelhantes nos dois tratamentos. A PA sistólica e a FC também aumentaram no exercício, mas seus valores absolutos foram significativamente menores com o atenolol. Porém, o aumento da PA sistólica e da FC no exercício foi semelhante com os dois tratamentos. Assim, o percentual da FCmáx e o percentual do VO2pico em que LA e PCR foram alcançados não diferiram entre o placebo e o atenolol. CONCLUSÃO: O atenolol na dosagem de 50 mg/dia não afetou o percentual do VO2pico e da FCmáx em que os LV são atingidos, o que confirma que a prescrição de intensidade de treinamento com base nessas porcentagens pode ser mantida em hipertensos que recebem betabloqueadores.

    Full Text Available A influência do biodiesel de soja na biodegradação dos hidrocarbonetos monoaromáticos benzeno e tolueno foi estudada sob condições anaeróbias em dois microcosmos montados com água subterrânea sintética, inóculo metanogênico, benzeno, tolueno e biodiesel. Na presença de biodiesel não foi observada biodegradação do benzeno e do tolueno. Com a biodegradação do biodiesel ocorreu a formação de acetato e metano, uso do sulfato e um aumento de 45 vezes no número de bactérias sulfato-redutoras. Esses resultados mostraram que, na mistura com benzeno e tolueno, o biodiesel foi biodegradado tanto sob condições de sulfato-redução quanto metanogênicas e que sua presença estimulou o crescimento da biomassa.

    Full Text Available Ethnic and linguistic changes of the Belarusian population at the turn of the 21th centuryThe first part of the article presents historical background of the origin of the Belarusian nation, located in the area of a confrontation between Russia and Poland. This rivalry was won by Russia, and in effect Belarusian land was incorporated into the Russian Empire, and later into the Soviet state. The next part presents the 20th century ethnic structure as the consequence of the Bolshevik Revolution and World Wars I and II, resulting in some border changes, war loses and migration movements. 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.

    This study was motivated by the need to improve densification of Global Horizontal Irradiance (GHI) observations, increasing the number of surface weather stations that observe it, using sensors with a sub-hour periodicity and examining the methods of spatial GHI estimation (by interpolation) with that periodicity in other locations. The aim of the present research project is to analyze the goodness of 15-minute GHI spatial estimations for five methods in the territory of Spain (three geo-statistical interpolation methods, one deterministic method and the HelioSat2 method, which is based on satellite images). The research concludes that, when the work area has adequate station density, the best method for estimating GHI every 15 min is Regression Kriging interpolation using GHI estimated from satellite images as one of the input variables. On the contrary, when station density is low, the best method is estimating GHI directly from satellite images. A comparison between the GHI observed by volunteer stations and the estimation model applied concludes that 67% of the volunteer stations analyzed present values within the margin of error (average of ±2 standard deviations).

    2010-01-01

    Pipeline blockage by gas hydrates is a serious problem in the petroleum industry.Low-dosage inhibitors have been developed for its cost-effective and environmentally acceptable characteristics.In a 1.072-L reactor with methane,ethane and propane gas mixture under the pressure of about 8.5 MPa at 4 °C,hydrate formation was investigated with low-dosage hydrate inhibitors PVP and GHI1,the change of the compressibility factor and gas composition in the gas phase was analyzed,the gas contents in hydrates were compared with PVP and GHI1 added,and the inhibition mechanism of GHI1 was discussed.The results show that PVP and GHI1 could effectively inhibit the growth of gas hydrates but not nucleation.Under the experimental condition with PVP added,methane and ethane occupied the small cavities of the hydrate crystal unit and the ability of ethane entering into hydrate cavities was weaker than that of methane.GHI1 could effectively inhibit molecules which could more readily form hydrates.The ether and hydroxy group of diethylene glycol monobutyl ether have the responsibility for stronger inhibition ability of GHI1 than PVP.

  14. A Comparison Between Heliosat-2 and Artificial Neural Network Methods for Global Horizontal Irradiance Retrievals over Desert Environments

    Global horizontal irradiance (GHI) retrievals at the surface of any given location could be used for preliminary solar resource assessments. More accurately, the direct normal irradiance (DNI) and diffuse horizontal irradiance (DHI) are also required to estimate the global tilt irradiance, mainly used for fixed flat plate collectors. Two different satellite-based models for solar irradiance retrievals have been applied over the desert environment of the United Arab Emirates (UAE). Both models employ channels of the SEVIRI instrument, onboard the geostationary satellite Meteosat Second Generation, as their main inputs. The satellite images used in this study have a temporal resolution of 15-min and a spatial resolution of 3-km. The objective of this study is to compare between the GHI retrieved using the Heliosat-2 method and an artificial neural network (ANN) ensemble method over the UAE. The high-resolution visible channel of SEVIRI is used in the Heliosat-2 method to derive the cloud index. The cloud index is then used to compute the cloud transmission, while the cloud-free GHI is computed from the Linke turbidity factor. The product of the cloud transmission and the cloud-free GHI denotes the estimated GHI. A constant underestimation is observed in the estimated GHI over the dataset available in the UAE. Therefore, the cloud-free DHI equation in the model was recalibrated to fix the bias. After recalibration, results over the UAE show a root mean square error (RMSE) value of 10.1% and a mean bias error (MBE) of -0.5%. As for the ANN approach, six thermal channels of SEVIRI were used to estimate the DHI and the total optical depth of the atmosphere (δ). An ensemble approach is employed to obtain a better generalizability of the results, as opposed to using one single weak network. The DNI is then computed from the estimated δ using the Beer-Bouguer-Lambert law. The GHI is computed from the DNI and DHI estimates. The RMSE for the estimated GHI obtained over an

    Full Text Available O artigo demonstra que as preocupações manifestadas por José Bonifácio quanto ao uso destrutivo dos recursos naturais, especialmente das florestas, representam um elemento básico e recorrente no seu pensamento político. A análise da evolução dos seus escritos, entre 1790 e 1823, revela uma permanente ligação do autor com a corrente científica conhecida como "economia da natureza", que se originou na Europa do século XVIII e é considerada um dos elos genealógicos mais imediatos na formação posterior da "ecologia". A reforma profunda na relação com o meio natural no Brasil, superando o padrão predatório de exploração herdado do colonialismo, configurou um dos eixos centrais do projeto nacional de Bonifácio, que incluía uma indicação bastante precisa das políticas públicas que seriam necessárias para realizar este objetivo. Sua principal contribuição foi demonstrar a existência de uma relação de causalidade entre o escravismo e a destruição ambiental.

Foram coletadas, no ano de 2007, amostras cloacais de 51 aves de dez espécies diferentes de cracídeos mantidos em cativeiros no Estado do Rio Grande do Sul. A partir dos swabs, colhidos assepticamente, foi realizado o isolamento e a caracterização bacteriana e o teste de susceptibilidade antimicrobiana dos isolados. Foram identificadas 93 cepas de bactérias. As bactérias mais frequentemente isoladas foram Escherichia coli, Staphylococcus spp. e Streptococcus spp. Todas as amostras foram negativas para o isolamento de Salmonella spp. O resultado do teste de sensibilidade mostrou que dentre as 93 cepas isoladas, todas foram sensíveis apenas ao imipinem. Adicionalmente, os menores percentuais de resistência foram observados frente ao cloranfenicol e ciprofloxacina. Os gêneros e espécies bacterianas com maior percentual de resistência a diferentes antibióticos testados foram Escherichia coli, Serratia marcescens, Staphylococcus aureus e Streptococcus spp. Com os resultados obtidos no presente trabalho, concluí-se, que a população de cracídeos estudada apresenta sua microbiota cloacal composta por vários gêneros e espécies bacterianas e que a multirresistencia pode ser um problema no futuro, uma vez que algumas cepas isoladas mostraram percentuais elevados de resistência a diferente antimicrobianos.Cracids are wildlife Galliformes which inhabits the America's tropical forests. Fifty one cloacal swabs were collected from 10 different species of captive cracids from the Rio Grande do Sul State during 2007. The cloacal swab samples were submitted to bacterial isolation, identification and, subsequently; antimicrobial susceptibility testing. Ninety three bacterial isolates were obtained from the cracid population examined. The most prevalent among the isolates were Escherichia coli, and bacteria from the Staphylococcus and Streptococcus genera. All samples tested in this study were negative for Salmonella spp. The antimicrobial susceptibility tests showed that none of the 93 strains presented resistance to the antimicrobial imipinem. In addition, the lower percentages of resistance were observed against cloranfenicol and ciprofloxacine. The bacteria genus and species with the highest percentage of resistance to the different antimicrobials examined were E. coli, Serratia marcescens, Staphylococcus spp. and Streptococcus spp. In conclusion, the data presented in this article demonstrate that the cloacal microbiota of the reported cracid population is composed of several bacterial genera and species and multi-drug resistance may be a problem for the future, since some strains showed elevated percentage of resistance against several different antimicrobials.

    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.

    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.

    The assessment of body composition has important applications in the evaluation of nutritional status and estimating potential health risks. Bioelectrical impedance analysis (BIA) is a valid method for the assessment of body composition. BIA is an alternative to more invasive and expensive methods like dual-energy X-ray absorptiometry, computerized tomography, and magnetic resonance imaging. Bioelectrical impedance analysis is an easy-to-use and low-cost method for the estimation of fat-free mass (FFM) in physiological and pathological conditions. The reliability of BIA measurements is influenced by various factors related to the instrument itself, including electrodes, operator, subject, and environment. BIA assumptions beyond its use for body composition are the human body is empirically composed of cylinders, FFM contains virtually all the water and conducting electrolytes in the body, and its hydration is constant. FFM can be predicted by BIA through equations developed using reference methods. Several BIA prediction equations exist for the estimation of FFM, skeletal muscle mass (SMM), or appendicular SMM. The BIA prediction models differ according to the characteristics of the sample in which they have been derived and validated in addition to the parameters included in the multiple regression analysis. In choosing BIA equations, it is important to consider the characteristics of the sample in which it has been developed and validated, since, for example, age- and ethnicity-related differences could sensitively affect BIA estimates.

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

    Directory of Open Access Journals (Sweden)

    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.

    The purpose of this investigation was to determine the accuracy of hand-to-hand bioelectrical impedance analysis (BIA) for estimating body composition in college-age female athletes using dual-energy X-ray absorptiometry (DEXA) as the criterion measure. Forty National Association for Intercollegiate Athletics college female athletes volunteered to participate in this study. For each participant, total body fat percentage (BF%) and fat-free mass (FFM) were obtained via BIA and DEXA. The mean BF% and FFM values obtained by BIA were compared with the criterion DEXA measure. The DEXA strongly correlated to the BIA for BF% (r = 0.74, R2 = 0.55, SEE = 3.60, and p < 0.01) and FFM (r = 0.84, R2 = 0.71, SEE = 2.45, p < 0.01). However, when compared with the DEXA, the mean values for BIA were significantly lower for BF% (DEXA = 27.6 ± 5.3%, BIA = 22.5 ± 3.5%, p < 0.01) and higher for FFM (DEXA = 47.2 ± 4.5 kg, BIA = 50.6 ± 4.6 kg, p < 0.01). The results of this investigation indicate that hand-to-hand BIA significantly underestimates BF% and overestimated FFM in college-age female athletes when compared with the criterion DEXA. Practitioners should use caution when analyzing body composition with hand-held BIA in a population of athletic women.

    2015-07-01

    Full Text Available BACKGROUND: Bioelectrical impedance (BIA seems an appropriate method for basic diagnostics of body composition in a practical environment. This is a non-time consuming non-invasive method that provides a high degree of response relevance. However, the values identifi ed by the BIA method are susceptible to a number of factors, which need to be taken into account during the investigation stage and interpretation of the results. One of the signifi cant factors infl uencing the outcomes of measurement is the instrument factor.OBJECTIVE: The objective of the present comparative survey was to analyse the proportions of body fat by means of the BIA hand-to-leg method and BIA leg-to-leg method in a sample of athletic individuals aged 7 to 18 years.METHODS: The survey included a total of 178 ice-hockey players aged 7 to 18 years. The proportion of body fat analysed by means of the BIA hand-to-leg method was measured by the Tanita BC-418 MA instrument. For the purposes of the BIA leg-to-leg method the Tanita BF-350 instrument was used (Tanita, Japan. Both instruments work at a frequency of 50 kHz.RESULTS: The percentage of body fat established by the BIA leg-to-leg method (M = 13.5%; SD = 4.8 indicated signifi cantly lower values of fat percentage than the values measured by the BIA hand-to-leg method (M = 17.1%; SD = 4.3. The overall diff erence represents an average value of 3.6% (standard mode; p < .001; d = 0.8. Regarding the monitored age categories the observed diff erences are in the range of 3.1–4.7% (p < .001; d = 0.7–1.2.CONCLUSION: The present study compares the proportions of body fat by means of the BIA leg-to-leg method and BIA hand-to-leg method in athletic boys aged 7 to 18 years. The results measured by the BIA leg-to-leg method signifi cantly undervalue the proportion of body fat in comparison with the BIA hand-to-leg method. The instrument factor and age factor represented signifi - cant variables infl uencing the results of the

    2016-03-01

    Bioelectrical impedance analysis (BIA) is a method for the assessment of nutritional status. We studied the effect of graft function on nutritional status in postrenal 45 transplant patients with borderline to good allograft function using BIA. The patients had a mean serum creatinine of 1.42 ± 0.42 mg% and mean glomerular filtration rate (GFR) of 45.1 ± 14.1 mL/min. Based on BIA-derived GFR, the patients were divided into two groups; group 1: borderline graft function GFR nutritional status compared with those in group 2. Based on phase angle, there were significant differences between group A (phase angle 4.0) in extracellular water (P nutritional status, but when compared with healthy individuals as assessed by BIA, there were significant differences in FM, FFM, and body cell mass. In conclusion, BIA was more sensitive to evaluate nutritional depletion than SGA in transplant patients with borderline.

    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

    Bioelectrical impedance analysis (BIA) is a common method for assessing body composition in research and clinical trials. BIA is convenient but when compared with other reference methods, the results have been inconclusive. The level of obesity degree in subjects is considered to be an important factor affecting the accuracy of the measurements. A total of 711 participants were recruited in Taiwan and were sub-grouped by gender and levels of adiposity. Regression analysis and Bland-Altman analysis were used to evaluate the agreement of the measured body fat percentage (BF%) between BIA and DXA. The BF% measured by the DXA and BIA methods (Tanita BC-418) were expressed as BF%DXA and BF%BIA8, respectively. A one-way ANOVA was used to test the differences in BF% measurements by gender and levels of adiposity. The estimated BF%BIA8 and BF%DXA in the all subjects, male and female groups were all highly correlated (r = 0.934, 0.901, 0.916, all P< 0.001). The average estimated BF%BIA8 (22.54 ± 9.48%) was significantly lower than the average BF%DXA (26.26 ± 11.18%). The BF%BIA8 was overestimated in the male subgroup (BF%DXA< 15%), compared to BF%DXA by 0.45%, respectively. In the other subgroups, the BF%BIA8 values were all underestimated. Standing BIA estimating body fat percentage in Chinese participants have a high correlation, but underestimated on normal and high obesity degree in both male and female subjects. PMID:27467065

    A methodology for the characterization of groups of polycyclic aromatic hydrocarbons (PAHs) using a combination of normal phase liquid chromatography with ultraviolet-visible spectroscopy (NPLC/UV-vis) and gas chromatography with mass spectrometry (GC/MS) was used for the identification and quantification of seven fused aromatic rings C26H14 peri-condensed benzenoid polycyclic aromatic hydrocarbons, PAHs, in standard reference material (SRM) 1597a, complex mixture of PAHs from coal tar. The NPLC/UV-vis isolated the fractions based on the number of aromatic carbons and the GC/MS allowed the identification and quantification of five of the nine C26H14 PAH isomers; naphtho[1,2,3,4-ghi]perylene, dibenzo[b,ghi]perylene, dibenzo[b,pqr]perylene, naphtho[8,1,2-bcd]perylene, and dibenzo[cd,lm]perylene using a retention time comparison with authentic reference standards. For the other four benzenoid isomers with no available reference standards the following two approaches were used. First, the annellation theory was used to achieve the potential identification of benzo[qr]naphtho[3,2,1,8-defg]chrysene, and second, the elution distribution in the GC fractions was used to support the potential identification of benzo[qr]naphtho[3,2,1,8-defg]chrysene and to reach the tentative identifications of dibenzo[a,ghi]perylene, naphtho[7,8,1,2,3-pqrst]pentaphene, and anthra[2,1,9,8-opqra]naphthacene. It is the first time that naphtho[1,2,3,4-ghi]perylene, dibenzo[b,ghi]perylene, dibenzo[b,pqr]perylene, naphtho[8,1,2-bcd]perylene, and dibenzo[cd,lm]perylene are quantified, and the first time that benzo[qr]naphtho[3,2,1,8-defg]chrysene is potentially identified, in any sample, in any context.

    This paper is concerned with the initial-boundary value problem for damped wave equations with a nonlinear convection term in the half space R+(utt-uxx+ut+f(u)x=0,t>0,z∈R+,(u(0,x)=u0(x)→u+, as x→+∞, (I)(ut(0,x)=u1(x),u(t,0)=ub.For the non-degenerate case,f'(u+)<0,it is shown in[1]that the above initialboundary value problem admits a unique global solution u(t,x)which converges to the stationary wave φ(x)uniformly in x∈R+as time tends to infinity provided that the initial perturbation and/or the strength of the stationary wave are sufficiently small.Moreover,by using the space-time weighted energy method initiated by Kawashima and Matsumura[2],the convergence rates(including the algebraic convergence rate and the exponential convergence rate)of u(t,x)toward φ(x)are also obtained in[1].We note,however,that the analysis in[1]relies heavily on the assumption that f'(ub)<0.The main purpose of this paper is devoted to discussing the case of f'(ub)=0 and we show that similar results still hold for such a case.Our analysis is based on some delicate energy estimates.

    Full Text Available O consumo máximo de oxigênio (VO2máx é a quantidade máxima de energia que pode ser produzida pelo metabolismo aeróbio em determinada unidade de tempo, podendo ser determinado direta ou indiretamente através de equações preditivas. O objetivo deste trabalho foi elaborar uma equação preditiva específica para determinar o VO2máx de meninos de 10 a 16 anos. Quarenta e dois meninos realizaram teste ergoespirométrico de corrida em esteira rolante com velocidade inicial de 9 km/h até exaustão voluntária. Através da regressão linear múltipla foi possível desenvolver a seguinte equação para a determinação indireta do VO2máx: VO2máx (ml/min = -1574,06 + (141,38 x Vpico + (48,34 * Massa corporal, com erro padrão de estimativa = 191,5 ml/min (4,10 ml/kg/min e o coeficiente de determinação = 0,934. Sugerimos que esta é uma fórmula adequada para predizer o VO2máx para esta população.The maximal oxygen uptake (VO2max is the maximal quantity of energy that can be produced by the aerobic metabolism in certain time unity. It can be determined direct or indirectly by predictive equations. The objective of this study was to make a specific predictive equation to determine the VO2max from boys aged 10-16 years-old. Forty-two boys underwent a treadmill running ergospirometric test, with the initial velocity set at 9 km/h, until voluntary exhaustion. By the multiple linear regression was possible to develop the following equation for the indirect determination of the VO2max: VO2max (ml/min = -1574.06 + (141.38 x Vpeak + (48.34 * Body mass, with standard error of estimate = 191.5 ml/min (4.10 ml/kg/min and coefficient of determination = 0.934. We suggest that this formula is appropriate to predict VO2max for this population.

    Full Text Available OBJECTIVE: To determine the degree of reproducibility of maximum oxygen consumption (VO2max among soccer players, using a modified Heck protocol. METHODS: 2 evaluations with an interval of 15 days between them were performed on 11 male soccer players. All the players were at a high performance level; they were training for an average of 10 hours per week, totaling 5 times a week. When they were evaluated, they were in the middle of the competitive season, playing 1 match per week. The soccer players were evaluated on an ergometric treadmill with velocity increments of 1.2 km.h-1 every 2 minutes and a fixed inclination of 3% during the test. VO2max was measured directly using a breath-by-breath metabolic gas analyzer. RESULTS: The maximum running speed and VO2max attained in the 2 tests were, respectively: (15.6 ± 1.1 vs. 15.7 ± 1.2 km.h-1; [P = .78] and (54.5 ± 3.9 vs. 55.2 ± 4.4 ml.kg-1.min-1; [P = .88]. There was high and significant correlation of VO2max between the 2 tests with a 15-day interval between them [r = 0.97; P OBJETIVO: Determinar o grau de reprodutibilidade do consumo máximo de oxigênio (VO2max em jogadores de futebol utilizando o protocolo de Heck modificado. MÉTODOS: Foram avaliados por duas vezes, com intervalo de 15 dias entre os testes, 11 futebolistas masculinos. Todos eram de alto nível, treinavam em média 10 horas por semana subdivididos em treinamentos físicos, técnicos, táticos e jogos competitivos, totalizando cinco vezes por semana e na fase em que foram avaliados se encontravam em pleno período competitivo realizando um jogo por semana. Os futebolistas foram avaliados em esteira ergométrica (1,2 km.h-1 a cada dois minutos e inclinação fixa durante o teste em 3%. O VO2max foi medido diretamente utilizando analisador metabólico de análise de gases expirados respiração-a-respiração. RESULTADOS: A velocidade máxima de corrida e o VO2max atingido nos dois testes foram respectivamente: (15,6 ± 1,1 vs. 15,7 ± 1,2 km.h-1; [p = 0,78] e (54,5 ± 3,9 vs. 55,2 ± 4,4 ml.kg-1.min-1; [P = 0,88]. Houve correlação significante e alta do VO2max entre os dois testes após 15 dias de intervalo [r = 0,97; P< 0,001]. CONCLUSÃO: O protocolo de Heck modificado foi reprodutível e o intervalo de quinze dias entre os testes ergoespirométricos não foi suficiente para modificar significativamente o VO2max dos jogadores de futebol.

    Full Text Available Gelfoam® - a biologically resorbable gelatin sponge - has the function of restricting hemorrhage, providing platelet rupture, and supporting fibrin threads. Beriplast® - a fibrinogen-thrombin compound - is used to adhere tissues, to consolidate sutures and in hemostasis. The objective of this study was to perform a histological analysis of the effects of haemostatic agents on osseous repair. These materials were inserted into surgical sites in young rat right and left tibiae. After the observation periods of 7, 14, 30 and 45 days, according to the bioethic protocol, the animals were killed, the tibiae were removed and fixed in 10% formalin and decalcified in equal parts of formic acid and sodium citrate solutions. After routine processing, the specimens were embedded in paraffin for microtomy. Analysis of the results demonstrated that the haemostatic agents are effective in controlling hemorrhage; they stimulate osteogenesis, featuring a pattern of osseous tissue formation similar to the control pattern, although the amount of osseous trabeculae was superior, especially in the Gelfoam group in the periods of 7 and 14 days; 30 days after surgery, the delay in tissue healing in the control group in relation to the experimental groups started to decrease, and the control and experimental groups exhibited similar tissue repair after 45 days, when all the groups exhibited secondary osseous tissue.Gelfoam® - uma esponja de gelatina biologicamente reabsorvível - tem por função coibir as hemorragias, promover o rompimento de plaquetas e sustentar a rede de fibrina. Beriplast P® - um composto de fibrinogênio-trombina - é usado na adesão de tecidos, consolidação de suturas e hemostasia. O objetivo deste estudo foi verificar histologicamente os efeitos de agentes hemostáticos na reparação óssea, os quais foram colocados em lojas cirúrgicas nas tíbias direita e esquerda de ratos jovens. Após os períodos de observação de 7, 14, 30 e 45 dias, segundo o protocolo bioético, os animais foram sacrificados, as tíbias foram removidas e fixadas em formalina a 10% e descalcificadas em partes iguais de soluções de ácido fórmico e citrato de sódio, para inclusão em parafina e microtomia. A análise dos resultados demonstrou que os agentes hemostáticos têm eficácia no controle hemorrágico; eles estimulam a osteogênese, provocando um padrão de formação de tecido ósseo semelhante ao padrão do grupo controle, embora a quantidade de trabéculas ósseas tenha sido superior principalmente no grupo do Gelfoam, nos períodos de 7 e 14 dias; após os 30 dias da cirurgia, o retardo na reparação tecidual do grupo controle em relação aos grupos experimentais começou a decrescer, tornando-se a reparação tecidual daquele semelhante à destes aos 45 dias, quando todos os grupos apresentaram tecido ósseo secundário.

    This paper presents the results of studies on gas sorption performed by means of the gravimetric method. The tests were performed on two coal samples of different metamorphism degrees, came from two regions of Upper Silesian Coal Basin, Poland. The changes in sorption capacity of coals were measured in the pressure range from 0.1 MPa to 17 MPa and in temperatures ranging from 291K to 333K. Coal of a lower coalification degree was a better methane sorbent. Changes in sorption capacity of tested coals were linearly dependent on the temperature. The increase in temperature of 10K reduces the Langmuir sorption of about 0.7-0.8 [cm3/g]. Such increase of temperature causes a nonlinear increase of the Langmuir pressure (b-1). These results showed that the rise of rock temperature, caused by geothermal gradient, can induce a significant increase of equilibrium pressure of methane in coal seam. An increase of coal seam temperature may cause an increase of gas and coal outburst risk in a coal mine. W pracy przedstawiono wyniki badań sorpcyjnych wykonanych na dwóch rodzajach węgla o różnym stopniu uwęglenia. Próbki do badań pochodziły z kopalń „Sobieski" w Jaworznie oraz „Pniówek" w Pawłowicach. Badania polegały na przeprowadzeniu serii pomiarów izoterm sorpcji w różnych temperaturach układu węgiel-metan. Badania przeprowadzono metodą grawimetryczną, polegającą na pomiarze zmian masy węgla wywołanych sorpcją metanu. Maksymalne ciśnienie sorpcji wynosiło 1.7 MPa. Zakres zmian temperatury wynosił 40K. Dla węgla z kopalni „Pniówek" wykonano dodatkowo pomiary desorpcji metanu we wszystkich badanych temperaturach. Wyniki pozwoliły na wyznaczenie izoterm sorpcji przedstawionych w pracy oraz dopasowanie współczynników izoterm Langmuir'a. Węgiel o niższym stopniu uwęglenia okazał się lepszym sorbentem dla metanu. Zmiany wartości maksymalnych sorpcji Langmuira w funkcji temperatury mają charakter liniowy a współczynniki kierunkowe prostych dopasowanych do wyników pomiaru mają bardzo zbliżone wartości. Analizując względne zmiany pojemności sorpcyjnej w procesach sorpcji i desorpcji można, że największe różnice pomiędzy wartościami sorpcji i desorpcji występują przy niskich wartościach ciśnień. Przy ciśnieniu 0.1 MPawynoszą one od ok. 16% do ok. 20%. Przy ciśnieniu powyżej 0.5 MPa wielkość histerezy nie przekracza 5%. W pracy przedstawiono również rozważania dotyczące wpływu zmian temperatury złożowej, wywołanego gradientem geotermicznym na zmiany ciśnienia równowagowego metanu w pokładzie. Do obliczenia wykonano dla przykładowych głębokości od od 600 m do 1400 m. Wyniki pokazują, że waz ze wzrostem metanonośności i głębokości gwałtownie może wzrastać ciśnienie równowagowe metanu w pokładach węgla. Ciśnienie metanu jest jednym z najważniejszych parametrów wpływających na możliwość występowania wyrzutów metanu i skał w kopalniach. Należy przypuszczać, że zagrożenie wyrzutami metanu i skał będzie wzrastało wraz z głębokością prowadzenia robót górniczych.

Este compósito também apresenta algumas propriedades favoráveis a seu emprego na área de blindagem balísticas, como por exemplo elevada dureza e alta resistência à abrasão. Nesse estudo foram produzidas amostras de Al2O3-YAG e Al2O3-YAG com Nb2O5 e Al2O3 com Nb2O5. Os pós precursores foram homogeneizados em moinho planetário de bolas por 4 h, secos em estufa a 120 ºC por 48 h, desaglomerados e peneirados. Os pós foram prensados uniaxialmente a 70 MPa. A sinterização foi realizada a 1450 ºC, com taxa de aquecimento e resfriamento de 10 ºC/min, durante 2, 3 e 4 h. Os materiais sinterizados foram caracterizados quanto à densidade pelo método de Arquimedes e avaliados microestruturalmente por microscopia eletrônica de varredura e difração de raios X com refinamento por Rietveld. As amostras Al2O3-YAG e Al2O3 aditivadas com Nb2O5 revelaram a presença da fase niobato de ítrio (YNbO4 e niobato de alumínio (AlNbO4 na ordem de 5 e 1% em peso, respectivamente. Não há registro na literatura desta adição a esse compósito. Os resultados mostraram que são necessários ainda ajustes nas condições de sinterização da composição Al2O3-YAG com Nb2O5 para maximizar a baixa densificação, da ordem de 60%. O Al2O3 aditivado com Nb2O5, por sua vez, apresentou uma densificação satisfatória, de 96%.The Al2O3-YAG composite has high mechanical strength at high temperatures which allows its use in air craft applications, since it increases the thermal efficiency of jet engines and helps the development of high performance gas turbines. This composite also exhibits some favorable properties toward military applications such as armor, due to its high hardness. In this study, Al2O3-YAG and Al2O3-YAG with 4wt.% Nb2O5 (niobia samples were produced. The precursors powders were ground in a planetary ball mill for 4 h, dried in an oven at 120 ºC during 48 h, deagglomerated and sieved. The powder mixtures were then uniaxially pressed at 70 MPa. Sintering was carried out at 1450 ºC for 2, 3, and 4 h, with heating and cooling rates of 10 ºC/min. The materials were characterized by scanning electron microscopy (SEM in order to characterize the microstructure. X-ray diffraction with Rietveld refinement was performed to determine and quantify the structural phases, whereas density was measured by the Archimede´s method. The samples with niobia addition revealed approximately 5wt.% of yttrium niobate (YNbO4 phase. It is worth pointing out that there is no citation in the literature involving niobia addition to the Al2O3-YAG composite. On the other hand, the obtained results indicated that additional experiments regarding the sintering conditions are necessary to optimize density.

    Full Text Available The objective of this study was to evaluate the quality and the production of biogas and biofertilizer obtained from biodigester supplied with pig feces in the initial, growing and finishing stages, fed with diets formulated based on corn or sorghum. Twenty bench biodigesters were used with hydraulic retention time of 30 days and daily loads that contained 4 to 6% of total solids (TS and 3.6 to 5.2% of volatile solids (VS. In the effluent of the biodigesters, mean levels of TS were observed ranging between 1.6 and 2.0% and of VS between 1.2 and 1.6%. The mean reductions of TS were 57.7 to 64.7% and of VS from 61.7 to 69.0%, and there was only difference in the finishing phase, in which the major averages reductions were produced by the biodigesters supplied with feces from animals fed with diets based on corn. In biodigesters supplied with feces from animals in the initial and growing stages fed with diets based on corn, were observed higher average productions of biogas and the greatest average potentials of biogas production. The average potentials obtained were 0.033; 0.181; 0.685; 0.788 and 1.132 m³ per kg of affluent, manure, TS added, VS added and VS reduced, respectively. No differences were found on the average content of methane in the biogas between diets and stages. The average concentrations of nutrients N, P, K, Ca, Mg, Na, Fe, Mn, Zn and Cu in the biodigester affluent and effluent, ranged between diets and stages.Objetivou-se avaliar a produção e a qualidade do biogás e do biofertilizante obtidos em biodigestores abastecidos com dejetos de suínos, nas fases inicial, crescimento e terminação, alimentados com dietas formuladas à base de milho ou sorgo.

    Full Text Available OBJETIVO: Comparar respostas cardiovasculares a Manobra Postural Passiva (Tilt Test e capacidade cardiorrespiratória em homens e mulheres de meia-idade antes e após treinamento físico aeróbio. MATERIAIS E MÉTODOS: Sete homens - GH (44,6±2,1 anos e sete mulheres - GM (51,7±4,8 anos, participaram de treinamento físico aeróbio por 12 semanas. Foi realizado protocolo de Tilt Test (cinco minutos supino, dez minutos inclinado 70º, cinco minutos supino, com monitoração da pressão arterial e freqüência cardíaca. Para mensuração da capacidade cardiorrespiratória foi realizado protocolo em cicloergômetro. RESULTADOS: Na condição sedentária, GH mostrou maior influência parassimpática no controle da freqüência cardíaca evidenciada por maior intervalo RR (iRR durante Tilt Test. Na condição treinada, os valores de iRR de ambos os grupos se assemelham, tendo as mulheres iRR maior em supino, mas na inclinação os homens mantêm iRR mais elevado. Para pressão arterial, as mulheres permanecem com valores superiores após treino, mas a freqüência cardíaca tende a se assemelhar em ambos. Já na capacidade cardiorrespiratória, homens e mulheres têm um padrão de comportamento semelhante após treino. Com exceção dos valores absolutos da freqüência cardíaca, sem diferenças entre os grupos, para todas as outras variáveis os homens obtiveram valores superiores aos das mulheres. Observa-se ainda que, após o treinamento, houve redução significativa dos valores de pressão arterial no GM, mesmo continuando superiores aos dos homens. CONCLUSÃO: O treinamento parece ter reduzido os níveis pressóricos nas mulheres, além de serem observadas melhorias na capacidade cardiorrespiratória de ambos os grupos, permanecendo os homens com melhor desempenho do que as mulheres.OBJECTIVE: To compare the cardiovascular responses to passive postural maneuvers (tilt test and the cardiorespiratory capacity in middle-aged men and women, before and after aerobic physical training. METHODS: Seven men (44.6±2.1 years old and seven women (51.7±4.8 years old participated in aerobic physical training for 12 weeks. The tilt test protocol (five minutes supine, ten minutes tilted at 70º and five minutes supine was followed, with arterial blood pressure and heart rate monitoring. A cycle ergometer protocol was used to measure cardiorespiratory capacity. RESULTS: In the sedentary condition, men showed greater parasympathetic influence in heart rate control, as demonstrated by their higher RR interval (iRR during the tilt test. After training, the iRR values became more similar in the two groups, although the women had higher iRR in the supine position and the men continued to present higher iRR under tilted conditions. The women's blood pressures continued to be higher after training, but heart rate tended to become similar in the two groups. The cardiorespiratory capacity patterns in the two groups were similar after training. Except for absolute heart rate values, for which there were no differences between the groups, the men's values were higher than those of the women for all other variables. It was also observed that, after the training, the women's blood pressures were significantly lower, even though their pressures remained higher than the men's. CONCLUSIONS: The training seemed to reduce the women's arterial blood pressure levels and improve both groups' cardiorespiratory capacity, but the men continued to present better performance than the women.

    Full Text Available The Ramlat as-Sab'atayn desert margin near Ma'rib, Yemen, displays well-preserved Early Holocene paleosols that are documented by micromorphological and pedological data. The buried soils, which are represented by Ahb horizons, indicate soil formation mostly before 8.3 cal ka BP. In contrast, sandy cover sediments without signs of pedogenesis appeared between 8.3 and 6.6 cal ka BP due to increasing aridity. Characteristic micromorphological features of the cover sediments are a single grain microstructure, crystallitic b-fabric, predominant occurrence of fresh sideromelane, and remnants of microlayers. Micromorphological pedogenic features in the buried Ah horizons include a subangular blocky microstructure, undifferentiated b-fabric as a result of enrichment of organic matter and decalcification, and the predominant occurrence of completely altered sideromelane. Most of these horizons appeared to be nearly completely decalcified so that in parts a stipple speckled b-fabric and neoformed clay coatings could be detected as a result of stronger weathering and soil formation. Pedogenic data provide important information about Holocene climate fluctuations, including the amount of precipitation, which was calculated on the basis of geochemical data from buried A, AB and B horizons. The buried paleosols represent moist climate conditions with precipitation ranging from 400 to 600 mm a-1.En los márgenes del desierto Ramlat as-Sab'atayn, cerca de Ma'rib (Yemen, se encuentran paleosuelos del Holoceno Inferior bien conservados que se documentan con datos micromorfológicos y edáficos. Los suelos enterrados, representados por horizontes Ahb, indican que se formaron mayoritariamente antes de hace 8,3 ka. Por el contrario, los sedimentos arenosos que los cubren sin rasgos de edafogénesis se depositaron posteriormente debido a una aridez creciente hasta hace 6,6 ka. Los rasgos micromorfológicos de los sedimentos arenosos están caracterizados por una microestructura granular sencilla, una fábrica birrefringente cristalítica, presencia predominante de sideromelana fresca y remanentes de microláminas. Los horizontes Ah enterrados tienen una microestructura en bloques subangulares, una fábrica birrefringente no diferenciada como resultado del enriquecimiento en materia orgánica y del proceso de descalcificación, y la presencia predominante de sideromelana completamente alterada. La mayoría de estos horizontes están casi descalcificados, por lo que en algunas partes se observa una fábrica birrefringente de motas en mosaico y revestimientos de arcilla neoformada como resultado de una fuerte meteorización y edafogénesis. Los datos edáficos aportan información importante sobre las fluctuaciones climáticas del Holoceno, en particular la cantidad de precipitación calculada a partir de los datos geoquímicos de los horizontes enterrados A, AB y B. Los paleosuelos enterrados indican condiciones de un clima húmedo con precipitaciones que varían entre 400 y 600 mm año-1.A margem deserta de Ramlat as-Sab'atayn próxima de Ma'rib, Yemen, apresenta paleosols antigos do Holoceno bem preservados, documentados por dados micromorfológicos e pedológicos. Os solos enterrados, representados por horizontes Ahb, indicam que a formação do solo ocorreu maioritariamente antes de 8,3 cal ka BP. Pelo contrário, a cobertura com sedimentos arenosos sem sinais de pedogénese surge devido ao aumento da aridez entre 8,3 e 6,6 cal ka BP. As características micromorfológicas desses sedimentos manifestam-se pela presença de uma microestrutura granular constituída por grânulos simples, material b-cristalítico, predominância de obsidiana de formação recente, e restos de microcamadas. As características pedogénicas micromorfológicas nos horizontes enterrados Ah manifestam-se pela presença de uma microestrutura em blocos subangulares, material-b indiferenciado como consequência do enriquecimento em matéria orgânica e descalcificação, e ocorrência predominante de obsidiana completamente alterada. A maioria destes horizontes encontra-se muito provavelmente próximo da descalcificação uma vez que em determinadas zonas é possível detectar material-b pontiagudo e neoformações de revestimentos de argila resultado do forte desgaste e formação de solo. Os dados pedogénicos fornecem informações importantes acerca das flutuações climáticas do Holoceno, incluindo a quantidade de precipitação, calculada com base em dados geoquímicos dos horizontes enterrados A, AB e B. Os Paleosols enterrados são indicativos de condições climáticas húmidas com uma precipitação variando entre 400 a 600 mm a-1.

    We report on the construction of generic models to calculate photosynthetically active radiation (PAR) from global horizontal irradiance (GHI), and vice versa. Our study took place at stations of the Greek UV network (UVNET) and the Hellenic solar energy network (HNSE) with measurements from NILU-UV multi-filter radiometers and CM pyranometers, chosen due to their long (≈1 M record/site) high temporal resolution (≈1 min) record that captures a broad range of atmospheric environments and cloudiness conditions. The uncertainty of the PAR measurements is quantified to be ±6.5% while the uncertainty involved in GHI measurements is up to ≈±7% according to the manufacturer. We show how multi-linear regression and nonlinear neural network (NN) models, trained at a calibration site (Thessaloniki) can be made generic provided that the input-output time series are processed with multi-channel singular spectrum analysis (M-SSA). Without M-SSA, both linear and nonlinear models perform well only locally. M-SSA with 50 time-lags is found to be sufficient for identification of trend, periodic and noise components in aerosol, cloud parameters and irradiance, and to construct regularized noise models of PAR from GHI irradiances. Reconstructed PAR and GHI time series capture ≈95% of the variance of the cross-validated target measurements and have median absolute percentage errors <2%. The intra-site median absolute error of M-SSA processed models were ≈8.2±1.7 W/m2 for PAR and ≈9.2±4.2 W/m2 for GHI. When applying the models trained at Thessaloniki to other stations, the average absolute mean bias between the model estimates and measured values was found to be ≈1.2 W/m2 for PAR and ≈0.8 W/m2 for GHI. For the models, percentage errors are well within the uncertainty of the measurements at all sites. Generic NN models were found to perform marginally better than their linear counterparts.

  20. Seasonal and geographical variation of Linke turbidity factor and its effect on global horizontal irradiance estimation: UAE case study

    In a clear-sky condition, solar radiation travelling through the Earth's atmosphere encounters atmospheric attenuation caused by several factors. Scattering of solar radiation is mainly caused by air molecules, water vapor, water droplets and dust. On the other hand, the absorption of solar radiation is usually related to the presence of O3, water vapor and CO2 layers in the upper atmosphere. Linke turbidity factor (TL) is commonly used to model the attenuation of solar radiation in the atmosphere. TL is the key parameter used in the Heliosat model, which is developed to estimate the global horizontal irradiance (GHI) at the surface of the earth. TL is calculated by the following equation: T_L=δ/δ_R where δ is the optical thickness of the whole atmosphere, and δR is the optical thickness of the Rayleigh atmosphere, i.e. the clear and dry atmosphere. The problem with TL is its dependence on the air mass (m). Therefore, TL is normalized to an air mass of 2 in order to reduce the daily variance. In this study, the monthly TL(m=2) is computed over 7 ground-based stations available in the UAE (figure 1). Spatial and temporal analysis was performed to assess the seasonal and the geographical distribution of TL over the UAE. The computed TL(m=2) values are then applied in the Heliosat model to compare between the measured and modeled GHI values. The model treats the atmospheric and cloud transmittances separately. First, clear-sky direct normal irradiance (DNI) and diffused horizontal irradiance (DHI) values are computed using TL(m=2), solar zenith angle, air mass, sun-earth distance correction, solar constant and the Rayleigh optical depth, from that the clear-sky GHI is determined. Next, the cloud index is derived from the HRV channel available from the SEVIRI instrument, and from that the cloud transmission is computed. The product of the cloud transmission and the clear-sky GHI produces the modeled GHI. The comparison between TL calculated over the seven stations

    Full Text Available Objective. To compare the measurements of body fat percentage (BF% using the foot-to-foot bioelectrical impedance analysis (FTF-BIA with the direct segmental multifrequency BIA (DSM-BIA. Methods. There were 36 men and 52 women (37.1±14.3 years with 57% Malays, 30% Chinese, and 13% Indian. For children, there were 45 boys and 26 girls (11.5±2.5 years with 52% Malay, 15% Chinese, and 33% Indian. Results. Mean height for men was 168.4 cm, 11 cm taller than women. Men were 10 kg heavier than women at 70 kg. BF% in women was 32% and 33% whereas BF% in men was 23% and 25% when measured using FTF-BIA and DSM-BIA, respectively. In children, BF% measured with FTF-BIA and DSM-BIA was 49% and 46%, respectively. The correlations were significant for men (r=0.92, SEE = 2.80, women (r=0.91, SEE = 3.31, boys (r=0.95, SEE = 5.44, and girls (r=0.96, SEE = 5.27. The BF% in underweight/normal (r=0.92, SEE = 2.47 and that in overweight/obese adults (r=0.89, SEE = 3.61 were strongly correlated. The correlations were significant in normal/underweight (r=0.94, SEE = 3.78 and obese/overweight children (r=0.83, SEE = 6.49. All ethnic groups showed significant correlation with BF%. Malay adults (r=0.92, SEE = 3.27 and children (r=0.94, SEE = 0.88 showed significant mean differences in BF%. Conclusion. The FTF-BIA showed higher accuracy for all normal/underweight and Chinese group with acceptable overestimation in children and underestimation in adults. Caution should be taken when interpreting BF% depending on gender, BMI, and ethnicity.

    Body composition measurements are valuable when evaluating pediatric obesity interventions. We hypothesized that foot-to-foot bioelectrical impedance analysis (BIA) will accurately track the direction of adiposity change, but not magnitude, in part due to differences in fat patterning. The purposes of this study were to examine the accuracy of body composition measurements of overweight and obese children over time using dual-energy x-ray absorptiometry (DXA) and BIA and to determine if BIA accuracy was affected by fat patterning. Eighty-nine overweight or obese children (48 girls, 41 boys, age 7-13 years) participating in a randomized controlled trial providing a family-centered, lifestyle intervention, underwent DXA and BIA measurements every 3 months. Bland-Altman plots showed a poor level of agreement between devices for baseline percent body fat (%BF; mean, 0.398%; +2SD, 8.685%; -2SD, -7.889%). There was overall agreement between DXA and BIA in the direction of change over time for %BF (difference between visits 3 and 1: DXA -0.8 ± 0.5%, BIA -0.7 ± 0.5%; P = 1.000) and fat mass (FM; difference between visits 3 and 1: DXA 0.7 ± 0.5 kg, BIA 0.6 ± 0.5 kg; P = 1.000). Bioelectrical impedance analysis measurements of %BF and FM at baseline were significantly different in those with android and gynoid fat (%BF: 35.9% ± 1.4%, 32.2% ± 1.4%, P < .003; FM: 20.1 ± 0.8 kg, 18.4 ± 0.8, P < .013). Bioelectrical impedance analysis accurately reports the direction of change in FM and FFM in overweight and obese children; inaccuracy in the magnitude of BIA measurements may be a result of fat patterning differences.

    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 cm{sup 2} 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)

    In France, market access for innovative drugs (level I, II & III improvement of medical service rendered having significant impact on health insurance expenditure) involves medico-economic evaluation. In addition to cost-effectiveness analysis (CEA), budget impact analysis (BIA) can be performed, especially since the sustainability of the health insurance system has become a growing concern for all stakeholders. The members of the Giens 2016 round table discussed the contribution of BIA based on a review of the literature on distribution models, the participants' experiences including experience related to the modalities of hospital assessments, and examples from other countries. The round table established recommendations on four elements of interest: 1: the use of BIA from a contractual point of view - between manufacturers and the French Economic Committee for Health Products - during the price negotiations process, and from a prospective point of view within the framework of the annual review of budget expenditures; the definition of the target population and the rhythm of a health product's distribution are also major elements; 2: the interpretation of BIA results in light of CEA results: for what products and at what moment in the life cycle of these products; 3: the integration of the rhythm of a health product's distribution into the BIA; 4: preoccupations about how the level of health product implementation is integrated into the BIA in terms of opportunity cost and organisational quality for the promoter.

    Benzylisoquinoline alkaloids (BIAs) are a large and diverse group of ~2500 specialized metabolites found predominantly in plants of the order Ranunculales. Research focused on BIA metabolism in a restricted number of plant species has identified many enzymes and cognate genes involved in the biosynthesis of compounds such as morphine, sanguinarine and berberine. However, the formation of most BIAs remains uncharacterized at the molecular biochemical level. Herein a compendium of sequence- and metabolite-profiling resources from 18 species of BIA-accumulating cell cultures was established, representing four related plant families. Our integrated approach consisted of the construction of EST libraries each containing approximately 3500 unigenes per species for a total of 58,787 unigenes. The EST libraries were manually triaged using known BIA-biosynthetic genes as queries to identify putative homologs with similar or potentially different functions. Sequence resources were analyzed in the context of the targeted metabolite profiles obtained for each cell culture using electrospray-ionization and collision-induced dissociation mass spectrometry. Fragmentation analysis was used for the identification or structural characterization coupled with the relative quantification of 72 BIAs, which establishes a key resource for future work on alkaloid biosynthesis. The metabolite profile obtained for each species provides a rational basis for the prediction of enzyme function in BIA metabolism. The metabolic frameworks assembled through the integration of transcript and metabolite profiles allow a comparison of BIA metabolism across several plant species and families. Taken together, these data represent an important tool for the discovery of BIA biosynthetic genes.

    To increase knowledge about reliability and intermethods agreement for body fat (BF) is of interest for assessment, interpretation, and comparison purposes. It was aimed to examine intra- and inter-rater reliability, interday variability, and degree of agreement for BF using air-displacement plethysmography (Bod-Pod), dual-energy X-ray absorptiometry (DXA), bioelectrical impedance analysis (BIA), and skinfold measurements in European adolescents. Fifty-four adolescents (25 females) from Zaragoza and 30 (14 females) from Stockholm, aged 13-17 years participated in this study. Two trained raters in each center assessed BF with Bod-Pod, DXA, BIA, and anthropometry (DXA only in Zaragoza). Intermethod agreement and reliability were studied using a 4-way ANOVA for the same rater on the first day and two additional measurements on a second day, one each rater. Technical error of measurement (TEM) and percentage coefficient of reliability (%R) were also reported. No significant intrarater, inter-rater, or interday effect was observed for %BF for any method in either of the cities. In Zaragoza, %BF was significantly different when measured by Bod-Pod and BIA in comparison with anthropometry and DXA (all P Bod-Pod, DXA, BIA, and anthropometry are reliable for %BF repeated assessment within the same day by the same or different raters or in consecutive days by the same rater. Bod-Pod showed close agreement with BIA as did DXA with anthropometry; however, Bod-Pod and BIA presented higher values of %BF than anthropometry and DXA.

    New approaches for assessment of lymphedema using ultrasonography (US) have been introduced recently and are reported to be reliable and simple. Ultrasonography provides detailed information about physical properties of the tissue in addition to volume and size. There have been only limited studies comparing bioimpedance analysis (BIA), US, and circumferential measurement (CM), which is considered a standard measurement. The aim of this study was to determine the relationship between US, BIA, and CM. Twenty-eight patients with lymphedema after breast cancer surgery underwent BIA, US, and CM. Impedance, which reflects the amount of extracellular fluid, was measured with 1 kHz frequency in affected and unaffected arms. Circumferences were measured at 10cm proximal and distal to the elbow and a truncated cone method used to calculate estimated volumes for upper arm and forearm. We found that interlimb forearm subcutis thickness differences measured by US were highly correlated with CM measurements and that interlimb upper arm subcutis thickness differences measured by US were moderately correlated with CM measurements and BIA ratios. However, the interlimb ratio of compressibility measured by US showed no or only weak correlation with impedance measurements and circumferential measurements. Our results also show that compressibility measured by US could not be predicted from BIA or CM measurements despite a high degree of concordance among subcutis thickness measured by US, CM, and BIA.

    Dialysis must control the body's fluid content accurately in order to maintain optimal health. The only commonly used, practical and objective measurements we have to guide fluid removal are very inaccurate. Recent study has validated bioimpedance (BIA) as an objective measure of fluid and nutritional status in dialysis patients. There are a number of different methods suitable for routine use available to the clinician. Single-frequency whole-body BIA uses inexpensive equipment capable of almost instantaneous or continuous measurement. The results can be used to give an indication of a patient's fluid content, nutrition and body composition when compared to appropriate reference values. Multiple-frequency whole-body BIA can be used to calculate excess fluid volume to within 1-2 liters. The equipment is more expensive than for single-frequency BIA, but the output is much easier to interpret. Multiple-frequency segmental BIA is more complicated to perform, but subject to less interference from changes in fluid distribution (e.g. resulting from hemodialysis or changes in posture). It is not suitable for routine use but could be considered as a gold standard for occasional clinical BIA.

    Full Text Available Abstract Background Shortages of health workers are obstacles to utilising global health initiative (GHI funds effectively in Africa. This paper reports and analyses two countries' health workforce responses during a period of large increases in GHI funds. Methods Health facility record reviews were conducted in 52 facilities in Malawi and 39 facilities in Zambia in 2006/07 and 2008; quarterly totals from the last quarter of 2005 to the first quarter of 2008 inclusive in Malawi; and annual totals for 2004 to 2007 inclusive in Zambia. Topic-guided interviews were conducted with facility and district managers in both countries, and with health workers in Malawi. Results Facility data confirm significant scale-up in HIV/AIDS service delivery in both countries. In Malawi, this was supported by a large increase in lower trained cadres and only a modest increase in clinical staff numbers. Routine outpatient workload fell in urban facilities, in rural health centres and in facilities not providing antiretroviral treatment (ART, while it increased at district hospitals and in facilities providing ART. In Zambia, total staff and clinical staff numbers stagnated between 2004 and 2007. In rural areas, outpatient workload, which was higher than at urban facilities, increased further. Key informants described the effects of increased workloads in both countries and attributed staff migration from public health facilities to non-government facilities in Zambia to PEPFAR. Conclusions Malawi, which received large levels of GHI funding from only the Global Fund, managed to increase facility staff across all levels of the health system: urban, district and rural health facilities, supported by task-shifting to lower trained staff. The more complex GHI arena in Zambia, where both Global Fund and PEPFAR provided large levels of support, may have undermined a coordinated national workforce response to addressing health worker shortages, leading to a less effective

    Solar energy is emerging as one of the top options for renewable energy sources in the Philippines, with largescale solar photovoltaic (PV) farms being built all over the country. Solar energy resource in the urban environment has great potential in making a city self-sustaining, but has not been fully explored for the country. In order to represent its potential, reliable resource assessment should be done. This study aims to assess the available solar energy resource in Davao City, a trade and commerce hub in southern Philippines. The functions of GRASS GIS, specifically the r.sun module, in modelling incoming solar radiation is discussed, along with the use of a one-meter LiDAR Digital Surface Model (DSM) and Linke Turbidity coefficients as inputs. The average Julian day of each month was used to compute the Global Horizontal Irradiation (GHI) values under clear-sky or cloudless conditions. To account for the effects of the clouds in the study area, the clear-sky indices (Kc) were computed using data from solar recording stations of the Bureau of Soils and Water Management (BSWM) found within and around the region. These were multiplied to the modelled clear-sky GHI rasters to get the real-sky GHI. The results show that the city's average GHI potential ranges from 2693.79 Wh/m2 and 4453.13 Wh/m2. Average values are particularly higher around the months of March and April, while lower values are seen in the months of November and January. Areas with higher potential are seen in the southern portion of the city, consistent in built-up areas.

    We present recent UV laboratory spectra of various polycyclic aromatic hydrocarbons (PAHs) and explore the potential of these molecules as carriers of the DIBs. From a detailed comparison of gas-phase and Ne-matrix absorption spectra of anthracene, phenanthrene, pyrene, 2,3-benzofluorene, benzo[ghi]perylene, and hexabenzocoronene with new interstellar spectra, we infer upper limits in the abundance of these PAHs in the interstellar medium. Upper limits in the column densities of anthracene of $0.8 - 2.8 \\times 10^{12}$\\ cm$^{-2}$ and of pyrene and 2,3-benzofluorene ranging from $2 - 8 \\times 10^{12}$\\ cm$^{-2}$ are inferred. Upper limits in the column densities of benzo[ghi]perylene are $0.9 - 2.4 \\times 10^{13}$ and $10^{14}$ cm$^{-2}$ for phenanthrene. The measurements indicate fractional abundances of anthracene, pyrene, and 2,3-benzofluorene of a few times $10^{-10}$. Upper limits in the fractional abundance of benzo[ghi]perylene of a few times $10^{-9}$ and of phenanthrene of few times $10^{-8}$ are infe...

    Full Text Available Hypertension is the most common medical problem encountered during pregnancy, complicating 2-3% of pregnancies. High blood pressure (BP with diastolic BP ≥ 90 mm Hg and/or systolic BP ≥ 140 mm Hg arising after week 22 of pregnancy and resolving after delivery is defined as gestational hypertension (GHY. The aim of this cross-sectional study was to investigate whether occupational and/or environmental exposure to organophosphorus (OP pesticide affects GHY. Women at approximately 22 weeks of gestation were recruited. OP pesticide exposure in the first trimester of pregnancy was classified into four categories: no exposure, indirect exposure, domestic exposure, and occupational exposure. Application of the exclusion criteria left 2203 participants (mean age 30.4 ± 11.6 years. Data analysis showed that in women with indirect OP pesticide exposure the incidence of GHY was slightly higher than that in the world population, whereas domestic exposure involved a 7% increase and occupational exposure a 12% increase. Analysis of the pesticides used by participants highlighted a possible role for malathion and diazinon (adjusted OR 1.09 and 1.14, resp.. Further investigation of exposed workers and the general population is clearly warranted given the broad diffusion of OP pesticides and their possible public health impact, maybe by including a wider range of health outcomes.

    For nearly 100 years, growth hormone (GH) has been known to affect insulin sensitivity and risk of diabetes. However, the tissue governing the effects of GH signaling on insulin and glucose homeostasis remains unknown. Excess GH reduces fat mass and insulin sensitivity. Conversely, GH insensitivity (GHI) is associated with increased adiposity, augmented insulin sensitivity, and protection from diabetes. Here, we induce adipocyte-specific GHI through conditional deletion of Jak2 (JAK2A), an obligate transducer of GH signaling. Similar to whole-body GHI, JAK2A mice had increased adiposity and extreme insulin sensitivity. Loss of adipocyte Jak2 augmented hepatic insulin sensitivity and conferred resistance to diet-induced metabolic stress without overt changes in circulating fatty acids. While GH injections induced hepatic insulin resistance in control mice, the diabetogenic action was absent in JAK2A mice. Adipocyte GH signaling directly impinged on both adipose and hepatic insulin signal transduction. Collectively, our results show that adipose tissue governs the effects of GH on insulin and glucose homeostasis. Further, we show that JAK2 mediates liver insulin sensitivity via an extrahepatic, adipose tissue–dependent mechanism. PMID:28194444

    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.

    Satellite derived global horizontal solar irradiance (GHI) from the SUNY modeled dataset in the National Solar Radiation Database (NSRDB) was compared to measurements from 27 weather stations in California during the years 1998-2005. The statistics of spatial and temporal differences between the two datasets were analyzed and related to meteorological phenomena. Overall mean bias errors (MBE) of the NSRDB-SUNY indicated a GHI overprediction of 5%, which is smaller than the sensor accuracy of ground stations. However, at coastal sites, year-round systematic positive MBEs in the NSRDB-SUNY data up to 18% were observed and monthly MBEs increased up to 54% in the summer months during the morning. These differences were explained by a tendency for the NSRDB-SUNY model to overestimate GHI under cloudy conditions at the coast during summer mornings. A persistent positive evening MBE which was independent of site location and cloudiness occurred at all stations and was explained by an error in the time-shifting method applied in the NSRDB-SUNY. A correction method was derived for these two errors to improve the accuracy of the NSRDB-SUNY data in California. (author)

    2011-12-01

    Full Text Available Human genetic defects in the growth hormone (GH –IGF-I axis affecting the IGF system present with growth failure as their principal clinical feature. This is usually associated with GH insensitivity (GHI presenting in childhood as severe or mild short stature. Dysmorphic features and metabolic abnormalities may also be present. The field of GHI due to mutations affecting GH action has evolved radidly since the first description of the extreme phenotype related to homozygous GH receptor (GHR mutations in 1966. A continuum of genetic, phenotypic, and biochemical abnormalities can be defined associated with clinically relevant defects in linear growth. The mechanisms of the GH–IGF-I axis in the regulation of normal human growth is discussed followed by descriptions of mutations in GHR, STAT5B, IGF-I, IGFALS, IGF1R and GH1 defects causing bioinactive GH or anti-GH antibodies. These GH-IGF-I axis defects are associated with a range of clinical, and hormonal characteristics. An up-dated approach to the clinical assessment of the patient with GHI focussing on investigation of the GH–IGF-I axis and relevant molecular studies contributing to the identification of causative genetic defects is also discussed.

    In the fall of 2002, GeoHazards International (GHI), a California-based nonprofit organization, launched two 3-year projects, each funded by the U.S. Agency for International Development, to improve the earthquake risk management of 23 cities in Central Asia and India. The objectives of these projects are to: * Assess the earthquake risk of each city, * Identify the most effective risk mitigation options for each city, * Raise awareness of that risk and those mitigation options, and * Initiate mitigation activities in some of these cities. A critical characteristic of these projects is that leaders of each local community will be deeply involved in realizing all four objectives. GHI will work with, in addition to local authorities, national government, academic and non-governmental organizations. In India, GHI’s partners are the Disaster Management Planning Hyogo Office, United Nations Centre for Regional Development (UNCRD) of Kobe, Japan, and the Sustainable Environment and Ecological Development Society (SEEDS), of Delhi, India. In India, we will work in 20 cities that were chosen, in a February 1, 2002 workshop (sponsored by Munich Reinsurance Company) in Delhi; the cities were selected by Indian earthquake professionals on the basis of the cities’ population, hazard, and economic, cultural and political significance. In Central Asia, we will focus on Tashkent, Uzbekistan; Dushanbe, Tadzhikistan; and Almaty, Kazakstan. GHI and its partners are looking for other organizations that would like to collaborate on these projects.

    José Ramón Alvero-Cruz

    Full Text Available The purpose of the present study was to investigate percentage body fat (%BF differences in three Spanish dance disciplines and to compare skinfold and bioelectrical impedance predictions of body fat percentage in the same sample. Seventy-six female dancers, divided into three groups, Classical (n=23, Spanish (n=29 and Flamenco (n=24, were measured using skinfold measurements at four sites: triceps, subscapular, biceps and iliac crest, and whole body multi-frequency bioelectrical impedance (BIA. The skin-fold measures were used to predict body fat percentage via Durnin and Womersley's and Segal, Sun and Yannakoulia equations by BIA. Differences in percent fat mass between groups (Classical, Spanish and Flamenco were tested by using repeated measures analysis (ANOVA. Also, Pearson's product-moment correlations were performed on the body fat percentage values obtained using both methods. In addition, Bland-Altman plots were used to assess agreement, between anthropometric and BIA methods. Repeated measures analysis of variance did not found differences in %BF between modalities (p<0.05. Fat percentage correlations ranged from r= 0.57 to r=0.97 (all, p<0.001. Bland-Altman analysis revealed differences between BIA Yannakoulia as a reference method with BIA Segal (-0.35 ± 2.32%, 95%CI: -0.89to 0.18, p=0.38, with BIA Sun (-0.73 ± 2.3%, 95%CI: -1.27 to -0.20, p=0.014 and Durnin-Womersley (-2.65 ± 2,48%, 95%CI: -3.22 to -2.07, p<0.0001. It was concluded that body fat percentage estimates by BIA compared with skinfold method were systematically different in young adult female ballet dancers, having a tendency to produce underestimations as %BF increased with Segal and Durnin-Womersley equations compared to Yannakoulia, concluding that these methods are not interchangeable.

    Despite the importance of sympathetic nervous system in pathophysiological mechanisms of cardiac heart failure and essential hypertension, therapy specifically targeting the sympathetic nervous system is currently underutilized. Etamicastat is a novel dopamine-ß-hydroxylase (DBH) inhibitor that is oxidized into BIA 5-965 and deaminated followed by oxidation to BIA 5-998, which represents 13% of total etamicastat and quantified metabolites. However, the primary metabolic pathway of etamicastat in rats was found to be the N-acetylation (BIA 5-961), which represents 44% of total etamicastat and quantified metabolites. Trace amounts of BIA 5-961 de-sulfated and S-glucuronide were also detected. All the main metabolites of etamicastat inhibited DBH with IC50 values of 306 (228, 409), 629 (534, 741), 427 (350, 522) nM for BIA 5-965, BIA 5-998 and BIA 5-961, respectively. However, only etamicastat (IC50 of 107 (94; 121) nM) was able to reduce catecholamine levels in sympathetic nervous system innervated peripheral tissues, without effect upon brain catecholamines. Quantitative whole body autoradiography revealed a limited transfer of etamicastat related radioactivity to brain tissues and the mean recovery of radioactivity was ~90% of the administered radioactive dose, eliminated primarily via renal excretion over 5 days. The absolute oral bioavailability of etamicastat was 64% of the administered dose. In conclusion, etamicastat is a peripheral selective DBH inhibitor mainly N-acetylated in the aminoethyl moiety and excreted in urine. Etamicastat main metabolites inhibit DBH, but only etamicastat demonstrated unequivocal pharmacological effects as a DBH inhibitor with impact upon the activity of the sympathetic nervous system under in vivo conditions.

    The results of investigation of the associated rocks with the Saddle Beds Coals Seams from Chwałowice Trough were presented in this article. The results of researches show that sandstones and mudstones dominate in the investigating profile. Claystones are situated mainly in ceilings and floors of coal seams. Grains of sandstones include mainly quartz, feldspars, micas and also quartzite's and gneiss's fragments. It is also possible to observe small grains of heavy minerals. Some of sandstones present bad compactness and are destroyed during transportation. This feature is connected with presence of little quantity of cement, especially in medium grained sandstones, which include more matrix than typical cement. The cement is built mainly of clay minerals, kaolinite and illite, carbonates and chalcedony but X-ray diffraction confirmed also the presence of halite in the cement of investigated sandstones. Mudstones and claystones are composed mainly of clay minerals. It's also possible to find quartz and micas there. Higher amounts of quartz and micas are possible to find rather in mudstones. The associated rocks with the Saddle Beds Coal Seams from Chwałowice Trough include also organic matter. W artykule przedstawiono wyniki badań skał towarzyszących pokładom węgla warstw siodłowych Niecki Chwałowickiej. Wyniki badań wskazują, że w badanym profilu dominują piaskowce oraz mułowce. Iłowce natomiast występują głównie w stropach i spągach pokładów węgla. Okruchy piaskowców to głównie ziarna kwarcu, skaleni, mik oraz fragmenty kwarcytów i gnejsów. Można tu również zaobserwować drobne okruchy minerałów ciężkich. Niektóre piaskowce charakteryzują się obniżoną zwięzłością i podczas transportu ulegają rozpadowi. Cecha ta związana jest z niewielką ilością spoiwa, szczególnie w piaskowcach średnioziarnistych, w których matrix przeważa nad typowym cementem. Spoiwo zbudowane jest głównie z minerałów ilastych, takich jak kaolinit i illit, węglanów i chalcedonu, chociaż wyniki dyfraktometrii rentgenowskiej potwierdziły występowanie w spoiwie badanych piaskowców również halitu. Na podstawie składu mineralnego piaskowców, dokonano ich klasyfikacji, stosując podziały skał okruchowych Krynina (1948) i Pettijohn'a-Potter'a-Siever'a (1973). Według klasyfikacji Krynina badane piaskowce reprezentują szarogłazy (szarowaki). W klasyfikacji Pettijohn'a, próbki 6, 8 i 13 reprezentują arenity lityczne, natomiast próbki 3 i 10- waki. Mułowce i iłowce zbudowane SA głównie z minerałów ilastych. Można w nich również spotkać ziarna kwarcu oraz miki. Wyższy udział kwarcu i mik jest jednak charakterystyczny dla mułowców. Skały towarzyszące pokładom węgla warstw siodłowych Niecki Chwałowickiej zawierają również domieszki substancji organicznej.

    Full Text Available This study aimed to establish a hand-to-hand (HH model for bioelectrical impedance analysis (BIA fat free mass (FFM estimation by comparing with a standing position hand-to-foot (HF BIA model and dual energy X-ray absorptiometry (DXA; we also verified the reliability of the newly developed model. A total of 704 healthy Chinese individuals (403 men and 301 women participated. FFM (FFMDXA reference variables were measured using DXA and segmental BIA. Further, regression analysis, Bland–Altman plots, and cross-validation (2/3 participants as the modeling group, 1/3 as the validation group; three turns were repeated for validation grouping were conducted to compare tests of agreement with FFMDXA reference variables. In male participants, the hand-to-hand BIA model estimation equation was calculated as follows: FFMmHH = 0.537 h2/ZHH − 0.126 year + 0.217 weight + 18.235 (r2 = 0.919, standard estimate of error (SEE = 2.164 kg, n = 269. The mean validated correlation coefficients and limits of agreement (LOAs of the Bland–Altman analysis of the calculated values for FFMmHH and FFMDXA were 0.958 and −4.369–4.343 kg, respectively, for hand-to-foot BIA model measurements for men; the FFM (FFMmHF and FFMDXA were 0.958 and −4.356–4.375 kg, respectively. The hand-to-hand BIA model estimating equation for female participants was FFMFHH = 0.615 h2/ZHH − 0.144 year + 0.132 weight + 16.507 (r2 = 0.870, SEE = 1.884 kg, n = 201; the three mean validated correlation coefficient and LOA for the hand-to-foot BIA model measurements for female participants (FFMFHH and FFMDXA were 0.929 and −3.880–3.886 kg, respectively. The FFMHF and FFMDXA were 0.942 and −3.511–3.489 kg, respectively. The results of both hand-to-hand and hand-to-foot BIA models demonstrated similar reliability, and the hand-to-hand BIA models are practical for assessing FFM.

    This study aimed to evaluate changes in total body water (TBW) in soccer athletes using a deuterium oxide dilution method and bioelectrical impedance (BIA) formulas after 7 days of creatine supplementation. In a double-blind controlled manner, 13 healthy (under-20) soccer players were divided randomly in 2 supplementation groups: Placebo (Pla, n=6) and creatine supplementation (CR, n=7). Before and after the supplementation period (0.3 g/kg/d during 7 days), TBW was determined by deuterium oxide dilution and BIA methods. 7 days of creatine supplementation lead to a large increase in TBW (2.3±1.0 L) determined by deuterium oxide dilution, and a small but significant increase in total body weight (1.0±0.4 kg) in Cr group compared to Pla. The Pla group did not experience any significant changes in TBW or body weight. Although 5 of 6 BIA equations were sensitive to determine TBW changes induced by creatine supplementation, the Kushner et al. 16 method presented the best concordance levels when compared to deuterium dilution method. In conclusion, 7-days of creatine supplementation increased TBW determined by deuterium oxide dilution or BIA formulas. BIA can be useful to determine TBW changes promoted by creatine supplementation in soccer athletes, with special concern for formula choice.

    Full Text Available An elephant survey was conducted in the Bia-Goaso Forest Block in western Ghana during the wet season month of November 2012 to determine the distribution of elephants and assess the human and ecological variables that affect them. One hundred and thirty 1-kilometre transects were systematically distributed in three strata (high, medium, and low density based on elephant dung pile density recorded in an initial reconnaissance. Elephant activity was concentrated in southern and mid-Bia Conservation Area, the southern tip of Bia North Forest Reserve, and eastern Mpameso Forest Reserve towards the adjoining Bia Shelter belt, indicating a clumped distribution. Secondary forest, water availability, poaching activity, and proximity to roads and settlements explained a high proportion of variance in elephant distribution. Given that the Bia-Goaso Forest Block forms an important biogeographic corridor between Ghana and Cote d’Ivoire, more effort should be directed at mitigating the problems such as poaching activity, vehicular traffic, and impacts of settlements that hinder seasonal movements of forest elephants between western Ghana and eastern Cote d’Ivoire.

    Full Text Available 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 < 0.0001. Additionally, 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.

    Full Text Available The current study aimed to compare the estimates of body fat percentage (%BF by performing bioelectrical impedance analysis (BIA and dual energy X-ray absorptiometry (DXA in a sample of obese or overweight Chinese adults who participated in a weight-loss randomized control trial stratified by gender to determine whether or not BIA is a valid measurement tool. Among 189 adults [73 males, 116 females; age = 41 to 74 years; mean body mass index (BMI = 27.3 kg/m(2], assessments of %BF at the baseline and six months from the baseline were conducted by performing BIA and DXA. Bland-Altman analyses and multiple regression analyses were used to assess the relationships between %BFBIA and %BFDXA. Compared with DXA, BIA underestimated %BF [in males: 4.6, -2.4 to 11.7 (mean biases, 95% limit of agreement at the baseline, 1.4, -7.4 to 10.2 at the endpoint, and 3.2, -4.8 to 11.3 in changes; in females: 5.1, -2.4 to 12.7; 2.2, -6.1 to 10.4; and 3.0, -4.8 to 10.7, respectively]. For males and females, %BFDXA proved to be a significant predictor of the difference between DXA and BIA at the baseline, the endpoint, and in changes when BMI and age were considered (in males: p<0.01 and R (2 = 23.1%, 24.1%, 20.7%, respectively; for females: p<0.001 and R (2 = 40.4%, 48.8%, 25.4%, respectively. The current study suggests that BIA provides a relatively accurate prediction of %BF in individuals with normal weight, overweight, or obesity after the end of weight-loss program, but less accurate prediction of %BF in obese individuals at baseline or weight change during the weight-loss intervention program.

  20. Benzylisoquinoline alkaloid metabolism: a century of discovery and a brave new world.

    Hagel, Jillian M; Facchini, Peter J

    2013-05-01

    Benzylisoquinoline alkaloids (BIAs) are a structurally diverse group of plant specialized metabolites with a long history of investigation. Although the ecophysiological functions of most BIAs are unknown, the medicinal properties of many compounds have been exploited for centuries. These include the narcotic analgesics codeine and morphine, the antimicrobial agents sanguinarine and berberine, and the antitussive and anticancer drug noscapine. BIA biosynthesis involves a restricted number of enzyme types that catalyze landmark coupling reactions and subsequent functional group modifications. A pathogenesis-related (PR)10/Bet v1 'Pictet-Spenglerase', several O-methyl-, N-methyl- and O-acetyltransferases, cytochromes P450, FAD-dependent oxidases, non-heme dioxygenases and NADPH-dependent reductases have been implicated in the multistep pathways leading to structurally diverse alkaloids. A small number of plant species, including opium poppy (Papaver somniferum) and other members of the Ranunculales, have emerged as model systems to study BIA metabolism. The expansion of resources to include a wider range of plant species is creating an opportunity to investigate previously uncharacterized BIA pathways. Contemporary knowledge of BIA metabolism reflects over a century of research coupled with the development of key innovations such as radioactive tracing, enzyme isolation and molecular cloning, and functional genomics approaches such as virus-induced gene silencing. Recently, the emergence of transcriptomics, proteomics and metabolomics has expedited the discovery of new BIA biosynthetic genes. The growing repository of BIA biosynthetic genes is providing the parts required to apply emerging synthetic biology platforms to the development of production systems in microbes as an alternative to plants as a commecial source of valuable BIAs.

  2. Phase sensitive spectral domain interferometry for label free biomolecular interaction analysis and biosensing applications

    Science.gov (United States)

    Chirvi, Sajal

    Biomolecular interaction analysis (BIA) plays vital role in wide variety of fields, which include biomedical research, pharmaceutical industry, medical diagnostics, and biotechnology industry. Study and quantification of interactions between natural biomolecules (proteins, enzymes, DNA) and artificially synthesized molecules (drugs) is routinely done using various labeled and label-free BIA techniques. Labeled BIA (Chemiluminescence, Fluorescence, Radioactive) techniques suffer from steric hindrance of labels on interaction site, difficulty of attaching labels to molecules, higher cost and time of assay development. Label free techniques with real time detection capabilities have demonstrated advantages over traditional labeled techniques. The gold standard for label free BIA is surface Plasmon resonance (SPR) that detects and quantifies the changes in refractive index of the ligand-analyte complex molecule with high sensitivity. Although SPR is a highly sensitive BIA technique, it requires custom-made sensor chips and is not well suited for highly multiplexed BIA required in high throughput applications. Moreover implementation of SPR on various biosensing platforms is limited. In this research work spectral domain phase sensitive interferometry (SD-PSI) has been developed for label-free BIA and biosensing applications to address limitations of SPR and other label free techniques. One distinct advantage of SD-PSI compared to other label-free techniques is that it does not require use of custom fabricated biosensor substrates. Laboratory grade, off-the-shelf glass or plastic substrates of suitable thickness with proper surface functionalization are used as biosensor chips. SD-PSI is tested on four separate BIA and biosensing platforms, which include multi-well plate, flow cell, fiber probe with integrated optics and fiber tip biosensor. Sensitivity of 33 ng/ml for anti-IgG is achieved using multi-well platform. Principle of coherence multiplexing for multi

    Full Text Available This paper presents a methodology to explore the impact on poverty of the public spending on education. The methodology consists of two approaches: Benefit Incidence Analysis (BIA and behavioral approach. BIA considers the cost and use of the educational service, and the distribution of the benefits among groups of income. Regarding the behavioral approach, we use a Probit model of schooling attendance, in order to determine the influence of public spending on the probability for the poor to attend the school. As a complement, a measurement of targeting errors in the allocation of public spending is included in the methodology.

    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 Δ14C 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.

    Concentrating solar power projects require accurate direct normal irradiance (DNI) data including uncertainty specifications for plant layout and cost calculations. Ground measured data are necessary to obtain the required level of accuracy and are often obtained with Rotating Shadowband Irradiometers (RSI) that use photodiode pyranometers and correction functions to account for systematic effects. The uncertainty of Si-pyranometers has been investigated, but so far basically empirical studies were published or decisive uncertainty influences had to be estimated based on experience in analytical studies. One of the most crucial estimated influences is the spectral irradiance error because Si-photodiode-pyranometers only detect visible and color infrared radiation and have a spectral response that varies strongly within this wavelength interval. Furthermore, analytic studies did not discuss the role of correction functions and the uncertainty introduced by imperfect shading. In order to further improve the bankability of RSI and Si-pyranometer data, a detailed uncertainty analysis following the Guide to the Expression of Uncertainty in Measurement (GUM) has been carried out. The study defines a method for the derivation of the spectral error and spectral uncertainties and presents quantitative values of the spectral and overall uncertainties. Data from the PSA station in southern Spain was selected for the analysis. Average standard uncertainties for corrected 10 min data of 2% for global horizontal irradiance (GHI), and 2.9% for DNI (for GHI and DNI over 300 W/m2) were found for the 2012 yearly dataset when separate GHI and DHI calibration constants were used. Also the uncertainty in 1 min resolution was analyzed. The effect of correction functions is significant. The uncertainties found in this study are consistent with results of previous empirical studies.

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

    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.

    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 Mānoa. 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.

The uncertainty of Si-pyranometers has been investigated, but so far basically empirical studies were published or decisive uncertainty influences had to be estimated based on experience in analytical studies. One of the most crucial estimated influences is the spectral irradiance error because Si-photodiode-pyranometers only detect visible and color infrared radiation and have a spectral response that varies strongly within this wavelength interval. Furthermore, analytic studies did not discuss the role of correction functions and the uncertainty introduced by imperfect shading. In order to further improve the bankability of RSI and Si-pyranometer data, a detailed uncertainty analysis following the Guide to the Expression of Uncertainty in Measurement (GUM) has been carried out. The study defines a method for the derivation of the spectral error and spectral uncertainties and presents quantitative values of the spectral and overall uncertainties. Data from the PSA station in southern Spain was selected for the analysis. Average standard uncertainties for corrected 10 min data of 2 % for global horizontal irradiance (GHI), and 2.9 % for DNI (for GHI and DNI over 300 W/m²) were found for the 2012 yearly dataset when separate GHI and DHI calibration constants were used. Also the uncertainty in 1 min resolution was analyzed. The effect of correction functions is significant. The uncertainties found in this study are consistent with results of previous empirical studies.

    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.

  9. Water Resources Impacts on Tribal Irrigation Projects

    Science.gov (United States)

    Minihane, M.

    2015-12-01

    The Bureau of Indian Affairs (BIA) Branch of Irrigation and Power provides oversight and technical support to select irrigation projects and systems on tribal lands. The BIA provides operations and maintenance support for 16 irrigation systems. To make the best use of limited resources, the BIA must incorporate climate change impacts on hydrology and water management for these irrigation systems in the coming decades. The 16 irrigation projects discussed here are divided into three climatological regions: the Pacific Northwest Region, the Greater Rocky Mountain Region, and the Western, Southwest, & Navajo Region. Significant climate projections that impact irrigation systems in one or more of these regions include increased temperatures and evaporative demand, earlier snowmelt and runoff, an increase in floods, an increase in heavy precipitation events, an increase in the frequency and intensity of droughts, and declining water supplies. Some irrigation projects are particularly vulnerable to these climate impacts because they are in already water-stressed areas or areas in which water resources are over-allocated. Other irrigation projects will have to adjust their storage and water management strategies to accommodate changes in the timing of streamflow. Overall, though, the BIA will be better able to assist tribal nations by incorporating expected climate impacts into their water resources management practices.

  10. Phase Angle, an Alternative Physiological Tool to Assess Wound Treatment in Chronic Nonhealing Wounds

    Science.gov (United States)

    Moore, Michael F.; Dobson, Nanci; Castelllino, Lisa; Kapp, Susan

    2011-01-01

    Background This exploratory study was conducted in an effort to demonstrate that bioelectrical impedance analysis (BIA) phase angle measurement is a novel tool for monitoring the effectiveness of a wound care regimen at a regional level and is valuable in comparing that status with the overall metabolic health of the patient. Isolating and measuring the extent to which nutritional supplementation contributes to the healing process is difficult and confounded by the many treatment modalities patients undergo. Objective The authors conducted a limited exploratory study to determine whether regional phase angle measurements accurately reflected the status of chronic nonhealing wounds. This information would potentially provide the ability to quantitatively evaluate of the role of nutritional supplementation in wounds of varying etiologies by comparing regional BIA phase angle measurement with overall BIA phase angle measurement. Methods Eleven patients with wounds of varying etiologies were selected to participate. Each patient underwent a treatment regimen specific to his or her condition, and all patients were given JUVEN® nutritional supplement. Results and Conclusion In all patients, the BIA phase angle measurement mirrored the health of the wound and provided an accurate tool for assessing the regional tissue health, a valuable insight in measuring the effectiveness of a systemic treatment.

  12. Parental involvement in brief interventions for adolescent marijuana use.

    Piehler, Timothy F; Winters, Ken C

    2015-09-01

    Adolescents (aged 12-18 years) identified in a school setting as abusing marijuana and other drugs were randomly assigned to complete 1 of 2 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 poorer marijuana use outcomes within the BI-A condition when compared to BI-AP. Co-occurring conduct problems were associated with poorer 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.

  13. Paleoecological interpretation of a Holocene sand body in the coastal area of Phetchaburi, Gulf of Thailand

    Directory of Open Access Journals (Sweden)

    Elio Robba

    2005-10-01

    Full Text Available Faunal examination is made of 4 samples, 2 from the Recent Ban Laem Phak Bia sand spit, and 2 from the Holocene sand body of Ban Bang Ket. Fossil and modern assemblages are compared on the basis of overall composition, taxa abundances, and of autoecological investigation on life habit, substrate preference, feeding type, depth range and ecological meaning of the identified species. The Holocene assemblage of Ban Bang Ket, compared to the Recent one of Ban Laem Phak Bia, 1 exhibits generally similar overall composition and ecological structure, 2 contains much of the dominant species characterizing the modern assemblage, and 3includes all taxa that are members of the living molluscan community. On this basis, the molluscan assemblage of Ban Bang Ket results to be the Holocene counterpart of the modern one of Ban Laem Phak Bia, and reflects the same environmental conditions recorded for the latter. Thus, the sand body near Ban Bang Ket is interpreted as a Holocene equivalent of the sand spit of Ban Laem Phak Bia.

  14. How to do (or not to do) ... a benefit incidence analysis.

    Science.gov (United States)

    McIntyre, Di; Ataguba, John E

    2011-03-01

    Benefit incidence analysis (BIA) considers who (in terms of socio-economic groups) receive what benefit from using health services. While traditionally BIA has focused on only publicly funded health services, to assess whether or not public subsidies are 'pro-poor', the same methodological approach can be used to assess how well the overall health system is performing in terms of the distribution of service benefits. This is becoming increasingly important in the context of the growing emphasis on promoting universal health systems. To conduct a BIA, a household survey dataset that incorporates both information on health service utilization and some measure of socio-economic status is required. The other core data requirement is unit costs of different types of health service. When utilization rates are combined with unit costs for different health services, the distribution of benefits from using services, expressed in monetary terms, can be estimated and compared with the distribution of the need for health care. This paper aims to provide an introduction to the methods used in the 'traditional' public sector BIA, and how the same methods can be applied to undertake an assessment of the whole health system. We consider what data are required, potential sources of data, deficiencies in data frequently available in low- and middle-income countries, and how these data should be analysed.

    2003-10-01

    Studies have suggested that long-term sauna bathing may lower blood pressure in persons with hypertension by causing a direct loss of extracellular water and plasma minerals. The objective of the present study was to evaluate the effect of short-term sauna bathing on body water compartments as estimated by bioelectric impedance analysis (BIA). We recruited 15 men [mean age (+/-SD) of 23.93+/-5.12 years and mean body mass index (BMI) of 23.25+/-2.84 kg/m(2)] and 10 women matched for age and BMI. Total body resistance, reactance, and impedance were measured for all participants using BIA, at baseline, after a short sauna bath, and after a rest period. Total, extracellular, and intracellular water compartments were calculated using BIA formulae. There were no significant differences for any of the body water compartments when comparing the measurements taken before and after the sauna bath and after the rest period. However, it remains to be determined whether or not BIA is sensitive to rapid changes in water volume.

    This book presents a selection of papers based on the XXXIII Białowieża Workshop on Geometric Methods in Physics, 2014. The Białowieża Workshops are among the most important meetings in the field and attract researchers from both mathematics and physics. The articles gathered here are mathematically rigorous and have important physical implications, addressing the application of geometry in classical and quantum physics. Despite their long tradition, the workshops remain at the cutting edge of ongoing research. For the last several years, each Białowieża Workshop has been followed by a School on Geometry and Physics, where advanced lectures for graduate students and young researchers are presented; some of the lectures are reproduced here. The unique atmosphere of the workshop and school is enhanced by its venue, framed by the natural beauty of the Białowieża forest in eastern Poland. The volume will be of interest to researchers and graduate students in mathematical physics, theoretical physics and m...

    Dyslipidemie to szerokie spektrum zaburzeń, charakteryzujące się nieprawidłowym stężeniem i/lub składem lipoprotein w surowicy krwi. Objawy te mogą towarzyszyć wtórnie innym chorobom, ale najczęściej mamy do czynienia z dyslipidemiami pierwotnymi, będącymi wynikiem interakcji czynników środowiskowych oraz predyspozycji genetycznych. W opracowaniu dokonano podsumowania stanu wiedzy na temat genetycznego podłoża dyslipidemii. Dotychczas polimorfizmy genowe skutkujące zaburzeniami lipidowymi opisano dla genów kodujących apolipoproteiny, białka receptorowe odpowiedzialne za transport lipoprotein do komórek, białka transportujące cholesterol z komórek obwodowych, białka transportujące estry cholesterolu i enzymy szlaku syntezy cholesterolu. W pracy przedstawiona została krótka charakterystyka tych genów i kodowanych przez nie białek oraz ich związek ze stężeniem lipidów we krwi.

    Full Text Available Background: Dry weight (DW is an important concept related to patients undergoing hemodialysis. Conventional method seems to be time consuming and operator dependent. Bio impedance analysis (BIA is a new and simple method reported to be an accurate way for estimating DW. In this study, we aimed to compare the conventional estimation of DW with measuring DW by BIA. Materials and Methods: This study involved 130 uremic patients, performed in Isfahan, Iran. DW was calculated by both conventional (CDW and BIA (BIADW method and results were compared based on different grouping factors including sex, underlying cause of renal failure (RF (diabetic RF and non-diabetic RF, body mass index (BMI status, and sessions of hemodialysis. We also calculated the difference between DWs of 2 methods (DW diff = CDW-BIADW. Results: The mean of BIADW was significantly lower than CDW (57.20 ± 1.82 vs 59.36 ± 1.77, P value < 0.001. After grouping cases according to the underlying cause, BMI, sex, and dialysis sessions BIADW was significantly lower than CDW. Conclusion: Based on the combination of problems with CDW measurement which are corrected by BIA, and more clinical reliability of CDW, we concluded that although conventional method is a time-consuming and operator-dependent way to assess DW, DW could be estimated by combining both of these methods by finding the mathematic correlation between these methods.

    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.

  10. Benefit-incidence analysis: are government health expenditures more pro-rich than we think?

    Science.gov (United States)

    Wagstaff, Adam

    2012-04-01

    Authors of benefit-incidence analyses (BIA) have to impute subsidies using assumptions about the relationship between unobserved subsidies 'captured' by the household and what can be observed at the household and aggregate levels. This paper shows that one of the two assumptions used in BIA studies to date will necessarily produce a more pro-rich (or less pro-poor) picture of government health spending than the other, depending on whether utilization is more pro-rich or pro-poor than fees paid to public providers. Both assumptions have their disadvantages, and the paper suggests a couple of alternatives that explicitly link fees paid to the costliness of care. It shows that in the most likely case where fees are distributed in a more pro-rich fashion than utilization, the two traditional assumptions will produce less pro-rich distributions of subsidies than the two new alternatives. Also considered are three complications that arise in BIA studies, including factoring in social health insurance. The paper's theoretical results are illustrated with an empirical BIA for Vietnam.

    2016-01-01

    Background Multifrequency bioelectrical impedance analysis (MF-BIA) is a technique that measures body impedance (Z) at different frequencies (5, 10, 50, 100, and 250 kHz). Body composition may be estimated using empirical equations, which include BIA variables or, alternatively, raw BIA data may provide direct information on water distribution and muscle quality. Objectives To compare raw MF-BIA data between COPD patients and controls and to study their relationship with respiratory and functional parameters in COPD patients. Methods MF-BIA was performed (Human Im-Touch analyzer) in 212 COPD patients and 115 age- and BMI-matched controls. Fat-free mass (FFM) and fat mass were estimated from BIA data, and low- to high-frequency (5 kHz/250 kHz) impedance ratio was calculated. Physical fitness, lung function and respiratory muscle strength were also assessed in COPD patients. Results After adjusting for age, weight, and body mass index, FFM and the 5/250 impedance ratio were lower in COPD patients (P<0.001) and were negatively affected by disease severity. In both male and female patients, the 5/250 impedance ratio was significantly correlated mainly with age (r=−0.316 and r=−0.346, respectively). Patients with a 5/250 impedance ratio below median value had lower handgrip strength (P<0.001), 6-minute walk distance (P<0.005), respiratory muscle strength (P<0.005), forced expiratory volume in 1 second (P<0.05) and vital capacity (P<0.005). Finally, the 5/250 impedance ratio was reduced (P<0.05) in patients with Global Initiative for Chronic Obstructive Lung Disease (GOLD) III and IV (compared to those with GOLD I and II) or a BODE index between 6 and 10 points (compared to those with BODE index between 1 and 5 points). Conclusion MF-BIA may be a useful tool for assessing body composition and nutritional status in COPD patients. In particular, the impedance ratio could give valuable information on cellular integrity and muscle quality.

  7. A randomized controlled trial of long term effect of BCM guided fluid management in MHD patients (BOCOMO study: rationales and study design

    Directory of Open Access Journals (Sweden)

    Liu Li

    2012-09-01

    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

    2007-11-01

    Full Text Available Abstract Background Methods used to estimate percent body fat can be classified as a laboratory or field technique. However, the validity of these methods compared to multiple-compartment models has not been fully established. This investigation sought to determine the validity of field and laboratory methods for estimating percent fat (%fat in healthy college-age women compared to the Siri three-compartment model (3C. Methods Thirty Caucasian women (21.1 ± 1.5 yrs; 164.8 ± 4.7 cm; 61.2 ± 6.8 kg had their %fat estimated by BIA using the BodyGram™ computer program (BIA-AK and population-specific equation (BIA-Lohman, NIR (Futrex® 6100/XL, a quadratic (SF3JPW and linear (SF3WB skinfold equation, air-displacement plethysmography (BP, and hydrostatic weighing (HW. Results All methods produced acceptable total error (TE values compared to the 3C model. Both laboratory methods produced similar TE values (HW, TE = 2.4%fat; BP, TE = 2.3%fat when compared to the 3C model, though a significant constant error (CE was detected for HW (1.5%fat, p ≤ 0.006. The field methods produced acceptable TE values ranging from 1.8 – 3.8 %fat. BIA-AK (TE = 1.8%fat yielded the lowest TE among the field methods, while BIA-Lohman (TE = 2.1%fat and NIR (TE = 2.7%fat produced lower TE values than both skinfold equations (TE > 2.7%fat compared to the 3C model. Additionally, the SF3JPW %fat estimation equation resulted in a significant CE (2.6%fat, p ≤ 0.007. Conclusion Data suggest that the BP and HW are valid laboratory methods when compared to the 3C model to estimate %fat in college-age Caucasian women. When the use of a laboratory method is not feasible, NIR, BIA-AK, BIA-Lohman, SF3JPW, and SF3WB are acceptable field methods to estimate %fat in this population.

    The aim of this study was to identify an adequate formulation for a poorly soluble lead molecule (BI-A) that would achieve sufficiently high plasma concentrations after oral administration in dogs to enable a robust cardiovascular safety pharmacology assessment in telemetry-instrumented conscious dogs during lead optimization in drug discovery. A spray-dried dispersion of BI-A (BI-A-SDD) containing a 1:2 ratio of BI-A and hydroxypropyl methylcellulose acetate succinate-LF was prepared using a Büchi spray dryer B-90 (B-90). Physical form characterization, an in vitro dissolution test and a preliminary pharmacokinetic (PK) study following oral administration of BI-A-SDD were performed. Thereafter, effects on cardiovascular parameters in conscious, chronically-instrumented dogs were investigated for 24h after a single oral dose (5, 10, and 50mg/kg) using a modified Latin square cross-over study design. The BI-A-SDD powder was confirmed to be amorphous and was stable as an aqueous suspension for at least 4h. The BI-A-SDD suspension provided a greater rate and extent of dissolution than the crystalline BI-A suspension and the supersaturation was maintained for at least 4h. In PK studies the Cmax of the BI-A-SDD formulation (25.4μM; 77-fold the projected efficacious Cmax of 0.33μM) was 7.5-fold higher than the Cmax observed using oral administration of a 10% hydroxypropyl-β-cyclodextrin formulation at 100mg/kg in dogs (3.4μM). In conscious, chronically-instrumented dogs, the doses tested and plasma concentrations achieved were sufficient to enable a robust safety pharmacology evaluation. Multiple off-target hemodynamic effects were detected including acute elevations in aortic blood pressure (up to 22% elevation in systolic and diastolic blood pressure) and tachycardia (68% elevation in heart rate), results that were confirmed in other in vivo models. These results led to a deprioritization of BI-A. The study demonstrated that a spray-dried dispersion, prepared

    Full Text Available Two hundred and fifty seven male Caucasian ultraendurance athletes were recruited, pre-race, before different swimming, cycling, running and triathlon races. Fat mass and skeletal muscle mass were estimated using bioelectrical impedance analysis (BIA and anthropometric methods in order to investigate whether the use of BIA or anthropometry would be useful under field conditions. Total body fat estimated using BIA was significantly high (P Se reclutaron a 257 hombres caucasianos que eran atletas de alto rendimiento, antes de competir en diferentes pruebas triatlón de natación, ciclismo y carrera. Se estimaron la masa grasa y la masa de músculo esquelético utilizando un análisis de impedancia bioeléctrica (BIA y métodos antropométricos con el fin de investigar si el uso de BIA o de la antropometría sería útil en tales condiciones de campo. La grasa corporal total estimada por BIA fue significativamente mayor en comparación con la antropometría (P < 0,001. Cuando se compararon los resultados entre BIA y antropometría, se encontraron niveles de concordancia bajos a moderados. Estos resultados concuerdan con las diferencias halladas con el análisis Bland-Altman, lo que indica que la ecuación antropométrica de Ball et al. posee el mayor grado de concordancia (desviación = -3,0 ± 5,8 kg con BIA, con Stewart et al. (desviación = -6,4 ± 6,3 kg, Faulkner (desviación = -4,7 ± 5,8 kg y Wilmore-Siri (desviación = -4,8 ± 6,2 kg. La estimación de la masa de músculo esquelético fue significativamente superior con BIAS que con antropometría (P < 0,001. Los resultados de la ICC y del método Bland-Altman muestran que la ecuación antropométrica de Lee et al. (desviación = -5,4 ± 5,3 kg produjo el mayor grado de concordancia. El método combinado de Janssen et al. entre antropometría y BIA mostró el menor grado de concordancia (desviación = -12,5 ± 5,7 kg.

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.

    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.

    Stratospheric sulfate aerosols from Plinian volcanic eruptions affect the solar surface irradiance forcing by scattering the solar radiation as it passes through the Earth atmosphere. Since these aerosols have high single scattering albedos they mostly affect direct normal irradiances (DNI). The effect on global horizontal irradiance (GHI) is less because some of the scattered irradiance reaches the surface as diffuse horizontal irradiance (DHI) and adds to the GHI. DNI is the essential input to concentrating solar thermal electric power (CSP/STE) and concentrated photovoltaic (CPV) plants. Therefore, an assessment of the future potential variability in the DNI resource caused by Plinian volcanic eruptions is desirable. Based on investigations of the El Chichón and Pinatubo eruptions, the microphysical, and thereby optical, properties of the stratospheric sulfate aerosols are well known. Given these, radiative transfer computations of the DNI resource can be made. The DNI resource includes forward scattered irradiance within the acceptance angle of a given CSP/STE or CPV plant. The rarity of Plinian eruptions poses a challenge for assessing the statistical risk of future eruptions and its potential of risk in the electricity production. Here we present and discuss methods to account for these potential volcanic eruptions for technical and economical studies including scenarios with very high probability of exceedance (e.g. P99 scenarios) for risk assessment of DNI-based solar power projects.

    GeoHazards International (GHI) has partnered with the University of California, Berkeley in a joint Civil Engineering and Earth Science summer internship program to investigate geologic hazards. This year the focus was on Aizawl, the capital of India's Mizoram state, situated on a ridge in the Burma Ranges. Nearby sources have the potential for large (M > 7) earthquakes that would be devastating to the approximately 300,000 people living in the city. Earthquake induced landslides also threaten the population as well as the city's lifelines. Fieldwork conducted in June 2015 identified hazards to vital water system components. The focus of this abstract is a review of the seismic hazards that affect Aizawl, with special attention paid to water system locations. To motivate action to reduce risk, GHI created an earthquake scenario describing effects of a M7 right-lateral strike-slip intraplate earthquake occurring 30 km below the city. We extended this analysis by exploring additional mapped faults as well as hypothetical blind reverse faults in terms of PGA, PGV, and PSA. Ground motions with hanging wall and directivity effects were also examined. Several attenuation relationships were used in order to assess the uncertainty in the ground motion parameters. Results were used to determine the likely seismic performance of water system components, and will be applied in future PSHA studies.

    The agronomic benefit of biochar has attracted widespread attention to biochar-based fertilizers. However, the inevitable presence of polycyclic aromatic hydrocarbons in biochar is a matter of concern because of the health and ecological risks of these compounds. The strong adsorption of polycyclic aromatic hydrocarbons to biochar complicates their analysis and extraction from biochar-based fertilizers. In this study, we optimized and validated a method for determining the 16 priority polycyclic aromatic hydrocarbons in biochar-based fertilizers. Results showed that accelerated solvent extraction exhibited high extraction efficiency. Based on a Box-Behnken design with a triplicate central point, accelerated solvent extraction was used under the following optimal operational conditions: extraction temperature of 78°C, extraction time of 17 min, and two static cycles. The optimized method was validated by assessing the linearity of analysis, limit of detection, limit of quantification, recovery, and application to real samples. The results showed that the 16 polycyclic aromatic hydrocarbons exhibited good linearity, with a correlation coefficient of 0.996. The limits of detection varied between 0.001 (phenanthrene) and 0.021 mg/g (benzo[ghi]perylene), and the limits of quantification varied between 0.004 (phenanthrene) and 0.069 mg/g (benzo[ghi]perylene). The relative recoveries of the 16 polycyclic aromatic hydrocarbons were 70.26-102.99%.

  17. A Neumann Boundary Term for Gravity

    2016-01-01

    The Gibbons-Hawking-York (GHY) boundary term makes the Dirichlet problem for gravity well defined, but no such general term seems to be known for Neumann boundary conditions. In this paper, we view Neumann {\\em not} as fixing the normal derivative of the metric ("velocity") at the boundary, but as fixing the functional derivative of the action with respect to the boundary metric ("momentum"). This leads directly to a new boundary term for gravity: the trace of the extrinsic curvature with a specific dimension-dependent coefficient. In three dimensions this boundary term reduces to a "one-half" GHY term noted in the literature previously, and we observe that our action translates precisely to the Chern-Simons action with no extra boundary terms. In four dimensions the boundary term vanishes, giving a natural Neumann interpretation to the standard Einstein-Hilbert action without boundary terms. We argue that in light of AdS/CFT, ours is a natural approach for defining a "microcanonical" path integral for gravit...

La diferencia de medias para FFS fue de -6,69,(CL -0,29, - 13.09) Hubo diferencias significativas entre las estimaciones de FFMI por BIA y DXA (FFS = 16,29, HFS = 14,95, DXA = 14,18). La diferencia de medias entre HFS y DXA fue = 0,78, (CL -2,27, 0,72) y la diferencia de medias de FFS fue -2,11: (CL -3,73 , -0,49). Conclusiones: Niveles diferentes de sesgo se observaron entre los equipos de BIA. El HFS parece ser más confiable que el FFS, sobre todo en la obtención de FFMI en mujeres jóvenes.

  20. Estimating Body Composition in Adolescent Sprint Athletes: Comparison of Different Methods in a 3 Years Longitudinal Design

    2015-01-01

    A recommended field method to assess body composition in adolescent sprint athletes is currently lacking. Existing methods developed for non-athletic adolescents were not longitudinally validated and do not take maturation status into account. This longitudinal study compared two field methods, i.e., a Bio Impedance Analysis (BIA) and a skinfold based equation, with underwater densitometry to track body fat percentage relative to years from age at peak height velocity in adolescent sprint athletes. In this study, adolescent sprint athletes (34 girls, 35 boys) were measured every 6 months during 3 years (age at start = 14.8 ± 1.5yrs in girls and 14.7 ± 1.9yrs in boys). Body fat percentage was estimated in 3 different ways: 1) using BIA with the TANITA TBF 410; 2) using a skinfold based equation; 3) using underwater densitometry which was considered as the reference method. Height for age since birth was used to estimate age at peak height velocity. Cross-sectional analyses were performed using repeated measures ANOVA and Pearson correlations between measurement methods at each occasion. Data were analyzed longitudinally using a multilevel cross-classified model with the PROC Mixed procedure. In boys, compared to underwater densitometry, the skinfold based formula revealed comparable values for body fatness during the study period whereas BIA showed a different pattern leading to an overestimation of body fatness starting from 4 years after age at peak height velocity. In girls, both the skinfold based formula and BIA overestimated body fatness across the whole range of years from peak height velocity. The skinfold based method appears to give an acceptable estimation of body composition during growth as compared to underwater densitometry in male adolescent sprinters. In girls, caution is warranted when interpreting estimations of body fatness by both BIA and a skinfold based formula since both methods tend to give an overestimation. PMID:26317426

  4. Global Horizontal Irradiance Anomalies in Long Term Series Over India

    India has a high potential for solar energy applications due to its geographic position within the Sun Belt and the large number of cloudless days in many regions of the country. However, certain regions of India, particularly those largely populated, can exhibit large aerosol loading in the atmosphere as a consequence of anthropogenic emissions that could have a negative feedback in the solar resource potential. This effect, named as solar dimming, has already been observed in India, and in some other regions in the world, by some authors using ground data from the last two decades. The recent interest in the promotion of solar energy applications in India highlights the need of extending and improving the knowledge of the solar radiation resources in this country, since most of the long term measurements available correspond to global horizontal radiation (GHI) and most of them are also located big cities or highly populated areas. In addition, accurate knowledge on the aerosol column quantification and on its dynamical behavior with high spatial resolution is particularly important in the case of India, due to their impact on direct normal irradiation. Long term studies of solar irradiation over India can be performed using monthly means of GHI measurements from the Indian Meteorological Department. Ground data are available from 1964 till today through the World Radiation Data Centre that publish these values in the web. This work shows a long term analysis of GHI using anomalies techniques over ten different sites over India. Besides, techniques of linear trends have been applied for to show the evolution over this period. The analysis of anomalies has also found two periods of different behavior. From 1964 till 1988 the anomalies observed were positive and the last 20 years seems to be a period of negative anomalies. The results exhibit a decreasing trend and negative anomalies confirming thus the darkening effect already reported by solar dimming studies

    Airborne particulate matter was collected using filter samplers and cascade impactors in six size fractions below 1.8 microm during a severe winter air pollution event at three sites in the Central Valley of California. The smallest size fraction analyzed was 0.056 source apportionment calculations. Colocated impactor and filter measurements were highly correlated (R8 > 0.8) for retene, benzo[ghi]flouranthene, chrysene, benzo[b]fluoranthene, benzo[k]fluoranthene, benzo[e]pyrene, benzo[a]pyrene, perylene, indeno[1,2,3-cd]pyrene, benzo[ghi]perylene, coronene, MW302 polycyclic aromatic hydrocarbon (PAHs), 17beta(H)-21alpha(H)-30-norhopane, 17alpha(H)-21beta(H)-hopane, alphabetabeta-20R-C29-ethylcholestane, levoglucosan, and cholesterol. Of these compounds, levoglucosan was present in the highest concentration (60-2080 ng m(-3)) followed by cholesterol (6-35 ng m(-3)), PAHs (2-38 ng m(-3)), and hopanes and steranes (0-2 ng m(-3)). Nighttime concentrations were higher than daytime concentrations in all cases. Organic compound size distributions were generally similar to the total carbon size distributions during the nighttime but showed greater variability during the daytime. This may reflect the dominance of fresh emission in the stagnant surface layer during the evening hours and the presence of aged organic aerosol at the surface during the daytime when the atmosphere is better mixed. All of the measured organic compound particle size distributions had a single mode that peaked somewhere between 0.18 and 0.56 microm, but the width of each distribution varied by compound. Cholesterol generally had the broadest particle size distribution, while benzo[ghi]perylene and 17alpha(H)-21beta(H)-29-norhopane generally had sharper peaks. The difference between the size distributions of the various particle-phase organic compounds reflects the fact that these compounds exist in particles emitted from different sources. The results of the current study will prove useful for size

    Full Text Available The successful electricity grid integration of solar energy into day-ahead markets requires at least hourly resolved 48 h forecasts. Technologies as photovoltaics and non-concentrating solar thermal technologies make use of global horizontal irradiance (GHI forecasts, while all concentrating technologies both from the photovoltaic and the thermal sector require direct normal irradiances (DNI. The European Centre for Medium-Range Weather Forecasts (ECMWF has recently changed towards providing direct as well as global irradiances. Additionally, the MACC (Monitoring Atmospheric Composition & Climate near-real time services provide daily analysis and forecasts of aerosol properties in preparation of the upcoming European Copernicus programme. The operational ECMWF/IFS (Integrated Forecast System forecast system will in the medium term profit from the Copernicus service aerosol forecasts. Therefore, within the MACC‑II project specific experiment runs were performed allowing for the assessment of the performance gain of these potential future capabilities. Also the potential impact of providing forecasts with hourly output resolution compared to three-hourly resolved forecasts is investigated. The inclusion of the new aerosol climatology in October 2003 improved both the GHI and DNI forecasts remarkably, while the change towards a new radiation scheme in 2007 only had minor and partly even unfavourable impacts on the performance indicators. For GHI, larger RMSE (root mean square error values are found for broken/overcast conditions than for scattered cloud fields. For DNI, the findings are opposite with larger RMSE values for scattered clouds compared to overcast/broken cloud situations. The introduction of direct irradiances as an output parameter in the operational IFS version has not resulted in a general performance improvement with respect to biases and RMSE compared to the widely used Skartveit et al.

    Malnutrition is a frequent complication of human immunodeficiency virus (HIV) infection and is associated with a poor prognosis. To compare different measures of nutritional status in HIV-infected patients, we prospectively studied 88 outpatients seen at a Paris AIDS outpatient clinic for routine follow-up examinations. Nutritional status was assessed according to body weight loss (BWL, 4 classes), anthropometry, bioelectric impedance analysis (BIA), and subjective global assessment of nutritional status (SGA). Malnutrition was diagnosed in 22.4% of subjects using SGA, and 37.1% by BWL. SGA rapidly detected a worsening of nutritional status, while BWL detected malnutrition at an earlier stage. A good correlation was found between SGA class and body composition assessed by anthropometry and BIA. Deteriorating nutritional status diagnosed by SGA correlated with the CDC HIV disease class. SGA, a simple nutritional assessment, can serve as a basis for prescribing artificial nutrition, while BWL detects malnutrition at an earlier stage.

    Full Text Available The aim of the study was to investigate the formation intensity of the urban heat island (UHI in Białystok, a relatively small city in north-eastern Poland. The UHI development was determined on the basis of meteorological data obtained from two weather stations of the Regional Inspectorate for Environmental Protection in Białystok, one located in the city center, and the other on its outskirts. The measurements of temperature gathered by automobile traverses along streets running from the city limits through the center were carried out in order to provide spatial diversity of the studied phenomenon. The results indicated that UHI in Bialystok is very clear. The intensity of this phenomenon changes in the daily cycle, with the peak in the evening. During the year the heat island is the most pronounced in the spring.

    A máxima fase estável de lactato (MFEL) é considerada padrão-ouro para a determinação da intensidade de transição metabólica aeróbia-anaeróbia em exercício contínuo, porém a resposta lactacidêmica nessa intensidade é, em humanos, dependente do ergômetro utilizado na avaliação. Uma ferramenta importante para estudos em fisiologia e áreas correlatas é a aplicação de modelos experimentais utilizando animais. Entretanto, ainda são restritas as pesquisas destinadas a investigar protocolos de avali...

    We examine zero-magnetic-field spin-dependent transmission in nonmagnetic semiconductor heterostructures with structural inversion asymmetry (SIA) and bulk inversion asymmetry (BIA), and report spin devices concepts that exploit their properties. Our modeling results show that several design strategies could be used to achieve high spin filtering efficiencies. The current spin polarization of these devices is electrically controllable, and potentially amenable to highspeed spin modulation, and could be integrated in optoelectronic devices for added functionality.

    Asian populations have a higher percentage body fat (%BF) and are at higher risk for CVD and related complications at a given BMI compared with those of European descent. We explored whether %BF was disproportionately elevated in rural Bangladeshi women with low BMI. Height, weight, mid-upper arm circumference, triceps and subscapular skinfolds and bioelectrical impedance analysis (BIA) were measured in 1555 women at 3 months postpartum. %BF was assessed by skinfolds and by BIA. BMI was calculated in adults and BMI Z-scores were calculated for females BMI and BMI Z-score cut-offs that optimally classified women as having moderately excessive adipose tissue (defined as >30 % body fat). Linear regressions estimated the association between BMI and BMI Z-score (among adolescents) and %BF. Mean BMI was 19·2 (sd 2·2) kg/m(2), and mean %BF was calculated as 23·7 (sd 4·8) % by skinfolds and 23·3 (sd 4·9) % by BIA. ROC analyses indicated that a BMI value of approximately 21 kg/m(2) optimised sensitivity (83·6 %) and specificity (84·2 %) for classifying subjects with >30 % body fat according to BIA among adults. This BMI level is substantially lower than the WHO recommended standard cut-off point of BMI ≥ 25 kg/m(2). The equivalent cut-off among adolescents was a BMI Z-score of -0·36, with a sensitivity of 81·3 % and specificity of 80·9 %. These findings suggest that Bangladeshi women exhibit excess adipose tissue at substantially lower BMI compared with non-South Asian populations. This is important for the identification and prevention of obesity-related metabolic diseases.

    OBJECTIVE: Body Adiposity Index (BAI), a new surrogate measure of body fat (hip circumference/[height 1.5-18]), has been proposed as a more accurate alternative to BMI. We compared BAI with BMI and their correlations with measures of body fat, waist circumference (WC), and indirect indices of fat pre- and post-Roux-en-Y gastric bypass (RYGB). METHODS: Sixteen clinically severe obese (CSO) non-diabetic women (age = 33.9± 7.9 SD; BMI = 46.5±9.5 kg/m(2)) were assessed pre-surgery, and at 2 (n=9) and 5 mo (n=8) post-surgery. Body fat percentage (% fat) was estimated with bioimpedance analysis (BIA), air displacement plethysmography (ADP), and dual-energy x-ray absorptiometry (DXA). WC, an indicator of central fat, and both plasma leptin (ng/ml) and insulin (mU/l) concentrations were measured as indirect body fat indices. Pre- and post-surgery values were analyzed with Pearson correlations and linear regressions. RESULTS: BAI and BMI correlated significantly with each other pre-surgery and at each time point post surgery. BAI and BMI also correlated significantly with % fat from BIA and ADP; however, only BMI correlated significantly with % fat from DXA pre- and post-RYGB. BMI was the single best predictor of WC and leptin at 2 and 5 mo post-surgery and had significant longitudinal changes correlating with % fat from BIA and DXA as well as with leptin. DISCUSSION: Both BAI and BMI were good surrogates of % fat as estimated from BIA and ADP, but only BMI was a good surrogate of % fat from DXA in CSO women. Thus, BAI may not be a better alternative to BMI.

    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.

    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.

    Recently, a body adiposity index (BAI = (hip circumference)/((height)(1.5))−18) was developed and validated in adult populations. The aim of this study was to evaluate the performance of BAI in estimating percentage body fat (BF%) in a sample of Colombian collegiate young adults. The participants were comprised of 903 volunteers (52% females, mean age = 21.4 years ± 3.3). We used the Lin’s concordance correlation coefficient, linear regression, Bland–Altman’s agreement analysis, concordance correlation coefficient (ρc) and the coefficient of determination (R2) between BAI, and BF%; by bioelectrical impedance analysis (BIA)). The correlation between the two methods of estimating BF% was R2 = 0.384, p < 0.001. A paired-sample t-test showed a difference between the methods (BIA BF% = 16.2 ± 3.1, BAI BF% = 30.0 ± 5.4%; p < 0.001). For BIA, bias value was 6.0 ± 6.2 BF% (95% confidence interval (CI) = −6.0 to 18.2), indicating that the BAI method overestimated BF% relative to the reference method. Lin’s concordance correlation coefficient was poor (ρc = 0.014, 95% CI = −0.124 to 0.135; p = 0.414). In Colombian college students, there was poor agreement between BAI- and BIA-based estimates of BF%, and so BAI is not accurate in people with low or high body fat percentage levels. PMID:28106719

  15. 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.

    We present the general design features and preliminary performances of a new system for the simultaneous AMS-{sup 14}C and IRMS δ{sup 13}C and δ{sup 15}N measurements on samples with masses in the μg 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 μgC 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.

    Ambient aerosol particles were collected using a five-stage impactor at six different sites in Delhi. The impactor segregates the TSPM into five different sizes (viz. >10.9, 10.9-5.4, 5.4-1.6, 1.6-0.7, and 10.9+10.9 to 5.4+5.4 to 1.6μm) and fine (1.6 to 0.7+<0.7μm). It was observed that the dominant PAHs found were pyrene, benzo(a)pyrene, benzo(ghi)perylene and benzo(b)fluoranthene for both the coarse and fine fractions. Source apportionment of polycyclic aromatic hydrocarbons (PAHs) has been carried out using principal component analysis method (PCA) in both coarse and fine size modes. The major sources identified in this study, responsible for the elevated concentration of PAHs in Delhi, are vehicular emission and coal combustion. Some contribution from biomass burning was also observed.

  18. Statistical cloud coverage as determined from sunshine duration: a model applicable in daylighting and solar energy forecasting

    2016-12-01

    A radiative/luminous energy budget is difficult to predict on a daily or hourly base if cloud coverage is obtained by subjective methods in discrete time points. A simple theoretical model that overcomes this shortcoming through interrelation of absolute cloud fraction and sunshine duration is presented. The latter is measured routinely at the meteorological stations worldwide. The model is based on statistical probability of clear line of sight, where Poisson spatial cloud distribution is analyzed for three different cloud shapes. A validation of the model using long-term measurements show a good correlation between experimentally determined and theoretically predicted data. The absolute cloud fraction obtained this way are a base for daylighting and solar energy applications including simulations of luminance/radiance sky distributions under different meteorological conditions. A simple calculation tool is developed and demonstrated on global horizontal illuminance (GHI).

    The bond nature in beryllium dimer has been theoretically investigated using high-level ab initio methods. A series of ANO basis sets of increasing quality, going from sp to spdf ghi contractions, has been employed, combined with HF, CAS-SCF, CISD, and MRCI calculations with several different active spaces. The quality of these calculations has been checked by comparing the results with valence Full-CI calculations, performed with the same basis sets. It is shown that two quasi-degenerated partly occupied orbitals play a crucial role to give a qualitatively correct description of the bond. Their nature is similar to that of the edge orbitals that give rise to the quasi-degenerated singlet-triplet states in longer beryllium chains.

    Full Text Available 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.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.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.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.

    The purpose of this study was to validate the percentage of body fat (%BF) values estimated from the BOD POD (BP) with those obtained from hydrostatic weighing (HW) in athletic American high school boys. Additionally, the %BF values measured via near-infrared interactance (NIR), bioelectrical impedance (BIA), and skinfold (SF) were compared to HW to determine the validity of these measures. Thirty white boys (mean age +/- SD = 15.8 +/- 1.0 years) who where currently participating in organized sports volunteered to have their %BF estimated. Measurements were obtained from NIR, BP, BIA, and SF in random order and concluded with HW. The findings from the present study indicated that the NIR and BIA instruments produced significant (P 4.0%BF). The BP produced a significantly (P 0.008) and had the lowest TE values compared to HW. These data suggest that the BP can produce acceptable body fat measures for athletic white boys but is not superior to estimates made by the SF equations used in this study.

    Full Text Available The main goal of the current research includes studying the biological signal field (BSF characteristics of the wolf (Canis lupus lupus Linnaeus, 1758 at different values of anthropogenic load on territories with conservation (Białowieża National park (Poland and hunting status of the species (Chornobyl Exclusion Zone (Ukraine. The research in Białowieża Primeval Forest was conducted in two stages: study of the BSF characteristics of the wolf and finding correlation between data acquired from Ukraine (the first stage, and over-time study of intensity of the biological signal field (the second stage. In result of the first stage, there was no significant dependence on the characteristics of the territory and the differences between the behavior of wolves in the Białowieża Primeval Forest (conservation status of the species and the Exclusion Zone (game status. During the second stage it was determined that provided variance of the intensity between territory groups was insufficient, the degree of significance to animals of area categories varied with the stages of the pack’s life. It was found that the main factors which govern the character of wolf activity are not the level of the anthropic load and hunting pressure, but periods of the life cycle and spatial structure of groups.

    Full Text Available Białowieza 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 Białowieza 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 Białowieza Forest area and they are the best place to settle for many species which are characteristic for swamps and small sources of water.

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

    1996-06-28

    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.

    The Mediterranean diet is a healthy dietary pattern known to actively modulate the cell membrane properties. Phase angle (PhA) is a direct measure by Bioelectrical Impedance Analysis (BIA) used as marker of cell membrane integrity. Both food behaviour and PhA are influenced by age, sex and body weight. The aim of this study was to cross-sectionally evaluate the association between the adherence to Mediterranean diet and PhA in 1013 healthy adult patients stratified according to sex, age, and body mass index (BMI). The adherence to the Mediterranean diet was evaluated using the PREvención con DIeta MEDiterránea (PREDIMED) questionnaire. PhA was calculated by BIA phase-sensitive system (50 kHz BIA 101 RJL, Akern Bioresearch, Florence, Italy Akern). In both sexes, at ROC analysis a PREDIMED score ≥ 6 predicted a PhA beyond the median value. At the multivariate analysis, among PREDIMED score, age, and BMI, the PREDIMED score was the major determinant of PhA, explaining 44.5% and 47.3% of PhA variability, in males and females respectively (p Mediterranean diet and PhA, independently of sex, age, and body weight. This association uncovered a new potential benefit of the Mediterranean diet on health outcomes, as in both sexes higher adherence to the Mediterranean diet was associated to larger PhAs, as expression of cell membrane integrity.

    Quick, easy-to-use, and valid body composition measurement options for young children are needed. Therefore, we evaluated the ability of the bioelectrical impedance (BIA) device, Tanita SC-240, to measure fat mass (FM), fat free mass (FFM) and body fatness (BF%) in 40 healthy, Swedish 5.5 years old children against the three component model (3C model). Average BF%, FM, and FFM for BIA were: 19.4% ± 3.9%, 4.1 ± 1.9 kg, and 16.4 ± 2.4 kg and were all significantly different (p model (25.1% ± 5.5%, 5.3 ± 2.5 kg, and 15.2 ± 2.0 kg). Bland and Altman plots had wide limits of agreement for all body composition variables. Significant correlations ranging from 0.81 to 0.96 (p model. When dividing the children into tertiles for BF%, 60% of children were classified correctly by means of BIA. In conclusion, the Tanita SC-240 underestimated BF% in comparison to the 3C model and had wide limits of agreement. Further work is needed in order to find accurate and easy-to-use methods for assessing body composition in pre-school children.

    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.

    Growing pharmaceutical interest in benzylisoquinoline alkaloids (BIA) coupled with their chemical complexity make metabolic engineering of microbes to create alternative platforms of production an increasingly attractive proposition. However, precise knowledge of rate-limiting enzymes and negative feedback inhibition by end-products of BIA metabolism is of paramount importance for this emerging field of synthetic biology. In this work we report the structural characterization of (S)-norcoclaurine-6-O-methyltransferase (6OMT), a key rate-limiting step enzyme involved in the synthesis of reticuline, the final intermediate to be shared between the different end-products of BIA metabolism, such as morphine, papaverine, berberine and sanguinarine. Four different crystal structures of the enzyme from Thalictrum flavum (Tf 6OMT) were solved: the apoenzyme, the complex with S-adenosyl-l-homocysteine (SAH), the complexe with SAH and the substrate and the complex with SAH and a feedback inhibitor, sanguinarine. The Tf 6OMT structural study provides a molecular understanding of its substrate specificity, active site structure and reaction mechanism. This study also clarifies the inhibition of Tf 6OMT by previously suggested feedback inhibitors. It reveals its high and time-dependent sensitivity toward sanguinarine.

    A horse's hydration status is critical to its health. The accurate and quantitative determination of it has been problematic because of size, length and density of hair, and uneven topography. The objective of this study was to validate a bioelectrical impedance analysis (BIA) method for objectively quantifying hydration status. Monofrequency BIA values and simple biometric measurements were used to construct predictive equations for total body water, plasma, extracellular, and intra-cellular fluid volumes. These predictive equations were correlated with standard body fluid dilution reference methods. The result was an accuracy of ±0.64% for total body water, ±0.17% for plasma volume, ±1.91% for extra-cellular fluid, and ±0.57% for intra-cellular fluid compartments. Less than 5 min was required for all of the measurements and determinations. Therefore, it appears that an accurate measurement of body fluid distribution can be performed on horses using a fast, easy, non-invasive, inexpensive BIA method.

    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 Δ14C 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.

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

    2010-02-01

    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 biogenic CH4 formation. 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/cm2/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.

    Several tests indicate that the transfer function gives a realistic approximation of the minimum potential GH inventory of low gas flux (LGF systems. The overall advantage of the presented function is its simplicity compared to complex numerical models: only two easily accessible parameters are needed.

    2016-06-21

    A hard cap espresso machine has been used in combination with liquid chromatography with molecular fluorescence detection for the determination of polycyclic aromatic hydrocarbons (PAHs) from contaminated soils and sediments providing appropriate extraction efficiencies and quantitative results. Naphthalene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, benz[a]anthracene, chrysene, benz[b]fluoranthene, benz[k]fluoranthene, benz[a]pyrene, dibenz[a,h]anthracene, benz[ghi]perylene, and indeno[1,2,3-cd]pyrene were used as target compounds. It should be mentioned that the pairs benz[a]anthracene-chrysene and dibenz[a,h]anthracene-benz[ghi]perylene peaks coelute under the employed chromatographic conditions; thus, those compounds were determined together. PAHs were extracted from 5.0 g of soil, previously homogenized, freeze-dried, and sieved to 250 μm, with 50 mL of 40% (v/v) acetonitrile in water at a temperature of 72 ± 3 °C. The proposed procedure is really fast, with an extraction time of 11 s, and it reduces the required amount of organic solvent to do the sample preparation. The obtained limit of detection for the evaluated PAHs was from 1 to 38 μg kg(-1). Recoveries were calculated using clean soils spiked with 100, 500, 1000, and 2000 μg kg(-1) PAHs with values ranging from 81 to 121% and good precision with relative standard deviation values lower than 30%. The method was validated using soil and sediment certified reference materials and also using real samples by comparison with ultrasound-assisted extraction, as reference methodology, obtaining statistically comparable results. Thus, the use of hard cap espresso machines in the analytical laboratories offers tremendous possibilities as low cost extraction units for the extraction of solid samples.

    In preparation for an outcomes study of benign prostatic hyperplasia (BPH), two measures of disease-specific health status were developed to supplement a symptom score and overall health status measures. The symptom problem index (SPI) captures how troublesome patients find their urinary symptoms. The BPH impact index (BII) measures how much their urinary problems affect various domains of health. A prospective revalidation of the refined instruments (N = 108 BPH patients and 50 controls) documented that both indices had good internal consistency (Cronbach's alpha = 0.88 and 0.79, respectively) and test-retest (r = 0.88 for both) reliabilities, correlated strongly with symptom scores (r = 0.86 and 0.77), and discriminated between BPH and control subjects (receiver-operating characteristic areas = 0.87 and 0.85, respectively). These indices were nearly as responsive as symptom scores in 50 men actively treated for BPH, and much more responsive than a non-disease-specific General Health Index (GHI), a Mental Health Index (MHI), and an Activity Index (AI). Finally, these measures capture most of the health status significance of BPH symptoms. In linear regression models constructed to predict scores on the GHI, MHI, and AI, symptom scores added little explanatory power to the SPI and, particularly, to the BII. These measures help clarify how BPH affects overall health status and function. Such measures have an important role to play in studies of the outcomes of treatment for BPH, and probably for other conditions that interfere with health status and function.

  18. Solar Forecasting Challenges and Opportunities for Enabling High Penetration of Solar Energy

    Mishra, S.

    2015-12-01

    In 2011, DOE launched the SunShot Initiative to reduce the total cost of solar energy systems by about 75% to make them cost competitive with other forms of energy (without subsidies) by 2020. This translates to a total cost of installed solar energy at 1/Watt or 0.06/kWh, incentivizing high penetration of solar on the utility grid. In the past four years, the SunShot Initiative has catalyzed revolutionary advancements in solar technologies, stimulating significant growth and accelerating deployment of solar energy systems. However, as solar deployment increases, integrating solar energy into the utility grid poses difficult challenges due to the variability in solar resource and the impact of clouds and aerosols on surface irradiance. Accurate forecasting of solar resource and its variability at high temporal and spatial resolution at least a day ahead is crucial to large scale integration of solar energy into the utility grid. However, this is limited by current errors in forecasting that are as high as 25% for clear sky forecasts of Global Horizontal Irradiance (GHI), and as large as 40-80% for cloudy conditions. Forecasting errors are even higher for the direct normal irradiance (DNI). For solar energy to be seamlessly integrated into the utility grid under the scenarios of high penetration of solar, significant improvements in surface solar irradiance modeling and observations of both Global Horizontal Irradiance (GHI) and Direct Normal Irradiance (DNI) are essential to accurately predict power outputs from photovoltaic (PV) and concentrating solar power (CSP) systems. Furthermore, forecasting improvements have to be closely tied to utility needs and operation timelines. Details about the ongoing research efforts supported through the SunShot initiative and the challenges and needs for solar forecasting improvements in regards to the SunShot Initiative will be presented at the conference.

    The impact of aerosols on the forecast accuracy of solar irradiance calculated by a fine-scale, one day-ahead, and operational numerical weather prediction model (NWP) is investigated in this study. In order to investigate the impact of aerosols only, the clear sky period is chosen, which is defined as when there are no clouds in the observation data and in the forecast data at the same time. The evaluation of the forecast accuracy of the solar irradiance is done at a single observation point that is sometimes affected by aerosol events. The analysis period is one year from April 2010 to March 2011. During the clear sky period, the root mean square errors (RMSE) of the global horizontal irradiance (GHI), direct normal irradiance (DNI), and diffuse horizontal irradiance (DHI) are 40.0 W m-2, 84.0 Wm-2, and 47.9 W m-2, respectively. During one extreme event, the RMSEs of the GHI, DNI, and DHI are 70.1 W m-2, 211.6 W m-2, and 141.7 W m-2, respectively. It is revealed that the extreme events were caused by aerosols such as dust or haze. In order to investigate the impact of the aerosols, the sensitivity experiments of the aerosol optical depth (AOD) for the extreme events are executed. The best result is obtained by changing the AOD to 2.5 times the original AOD. This changed AOD is consistent with the satellite observation. Thus, it is our conclusion that an accurate aerosol forecast is important for the forecast accuracy of the solar irradiance.

    Full Text Available A bankable solar radiation database is required for the financial viability of solar energy project. Accurate estimation of solar energy resources in a country is very important for proper siting, sizing and life cycle cost analysis of solar energy systems. During the last decade an important progress has been made to develop multiple solar irradiance database (Global Horizontal Irradiance (GHI and Direct Normal Irradiance (DNI, using satellite of different resolution and sophisticated models. This paper assesses the performance of High-resolution solar irradiance derived with dynamical downscaling Numerical Weather Prediction model with, GIS topographical solar radiation model, satellite data and ground measurements, for the production of bankable solar radiation datasets. For this investigation, NWP model namely Consortium for Small-scale Modeling (COSMO is used for the dynamical downscaling of solar radiation. The obtained results increase confidence in solar radiation data base obtained from dynamical downscaled NWP model. The mean bias of dynamical downscaled NWP model is small, on the order of a few percents for GHI, and it could be ranked as a bankable datasets. Fortunately, these data are usually archived in the meteorological department and gives a good idea of the hourly, monthly, and annual incident energy. Such short time-interval data are valuable in designing and operating the solar energy facility. The advantage of the NWP model is that it can be used for solar radiation forecast since it can estimate the weather condition within the next 72–120 hours. This gives a reasonable estimation of the solar radiation that in turns can be used to forecast the electric power generation by the solar power plant.

    Full Text Available Abstract Background A frequent manifestation of advanced lung cancer is malnutrition, timely identification and treatment of which can lead to improved patient outcomes. Bioelectrical impedance analysis (BIA is an easy-to-use and non-invasive technique to evaluate changes in body composition and nutritional status. We investigated the prognostic role of BIA-derived phase angle in advanced non-small cell lung cancer (NSCLC. Methods A case series of 165 stages IIIB and IV NSCLC patients treated at our center. The Kaplan Meier method was used to calculate survival. Cox proportional hazard models were constructed to evaluate the prognostic effect of phase angle, independent of stage at diagnosis and prior treatment history. Results 93 were males and 72 females. 61 had stage IIIB disease at diagnosis while 104 had stage IV. The median phase angle was 5.3 degrees (range = 2.9 – 8. Patients with phase angle 5.3 had 12.4 months (95% CI: 10.5 to 18.7; n = 84; (p = 0.02. After adjusting for age, stage at diagnosis and prior treatment history we found that every one degree increase in phase angle was associated with a relative risk of 0.79 (95% CI: 0.64 to 0.97, P = 0.02. Conclusion We found BIA-derived phase angle to be an independent prognostic indicator in patients with stage IIIB and IV NSCLC. Nutritional interventions targeted at improving phase angle could potentially lead to an improved survival in patients with advanced NSCLC.

    Czynnik wzrostu fibroblastów 21 należy do heterogennej rodziny białek FGF. Odgrywa on ważną rolę w metabolizmie węglowodanów i lipidów. Jest produkowany przez hepatocyty, białą tkankę tłuszczową, komórki trzustki oraz mięśni szkieletowych. Hormon ten stymuluje glukoneogenezę, oksydację wolnych kwasów tłuszczowych i ketogenezę w wątrobie. Czynniki transkrypcyjne obecne w wątrobie (PPAR-α) oraz w adipocytach (PPAR-γ) kontrolują jego ekspresję komórkową. Podwyższony poziom FGF21 w surowicy jest asocjowany z niektórymi chorobami, w których patogenezie kluczowym mechanizmem jest oporność na insulinę, tj.: otyłością, cukrzycą typu 2, upośledzoną tolerancją glukozy oraz zespołem metabolicznym. Szlaki metaboliczne w wątrobie i białej tkance tłuszczowej są regulowane także przez inne hormony (leptyna, adiponektyna, omentyna, rezystyna, waspina, wisfatyna, apelina oraz chemeryna) oraz enzym G3PP. Substancje te odgrywają ważną rolę w rozwoju chorób związanych z zaburzeniami gospodarki węglowodanowo-lipidowej.

    Railway transport is a source of pollution to soils and living organisms by e.g. PAHs, PCBs, oil-derived products, pesticides and heavy metals. Soil toxicity evaluation requires chemical analyses, indicating the type and content of particular pollutants, as well as biological analyses, which allow assessing the reaction of organisms to these pollutants. This paper is focused on a multi-aspect evaluation of the degree of toxicity and pollution of soil in selected railway areas from north-eastern Poland by application of numerous biotests and chemical analyses. The soils were sampled on railway tracks from the following railway stations: Białystok Fabryczny, Siemianówka, Hajnówka, Iława Główna and Waliły. The most toxic soils occur on the railway tracks at Białystok Fabryczny and Siemianówka. They had a significant toxic effect on test organisms from various trophic levels. The contents of PAHs, PCBs, heavy metals, oil-derived hydrocarbons and pesticide residues were determined in the examined soils. In all cases the detected pollutants did not exceed the admissible levels. The highest content of oil-derived substances was noted in soils from Białystok Fabryczny and concentrations were moderate in soils from Siemianówka. Although the pollutants determined in soils from railway tracks did not exceed the admissible values, they had a toxic effect on numerous test organisms from different trophic levels. This suggests a synergistic effect of low concentrations (within the admissible levels) of several pollutants together, which resulted in a toxic effect on the organisms. Thus, there is a strong need of not only chemical, but also ecotoxicological analyses during the evaluation of environmental conditions. Based on data obtained from biological and chemical analyses, we concluded that railway transport may pose a hazard to the natural environment to a larger extent that hitherto expected.

    Benzylisoquinoline alkaloids (BIAs) are a group of nitrogen-containing plant secondary metabolites comprised of an estimated 2500 identified structures. In BIA metabolism, (S)-reticuline is a key branch-point intermediate that can be directed into several alkaloid subtypes with different structural skeleton configurations. The morphinan alkaloids are one subclass of BIAs produced in only a few plant species, most notably and abundantly in the opium poppy (Papaver somniferum). Comparative transcriptome analysis of opium poppy and several other Papaver species that do not accumulate morphinan alkaloids showed that known genes encoding BIA biosynthetic enzymes are expressed at higher levels in P. somniferum. Three unknown cDNAs that are co-ordinately expressed with several BIA biosynthetic genes were identified as enzymes in the pathway. One of these enzymes, salutaridine reductase (SalR), which is specific for the production of morphinan alkaloids, was isolated and heterologously overexpressed in its active form not only from P. somniferum, but also from Papaver species that do not produce morphinan alkaloids. SalR is a member of a class of short chain dehydrogenase/reductases (SDRs) that are active as monomers and possess an extended amino acid sequence compared with classical SDRs. Homology modelling and substrate docking revealed the substrate binding site for SalR. The amino acids residues conferring salutaridine binding were compared to several members of the SDR family from different plant species, which non-specifically reduce (-)-menthone to (+)-neomenthol. Previously, it was shown that some of these proteins are involved in plant defence. The recruitment of specific monomeric SDRs from monomeric SDRs involved in plant defence is discussed.

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.

    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 The Mediterranean diet is a healthy dietary pattern known to actively modulate the cell membrane properties. Phase angle (PhA is a direct measure by Bioelectrical Impedance Analysis (BIA used as marker of cell membrane integrity. Both food behaviour and PhA are influenced by age, sex and body weight. The aim of this study was to cross-sectionally evaluate the association between the adherence to Mediterranean diet and PhA in 1013 healthy adult patients stratified according to sex, age, and body mass index (BMI. The adherence to the Mediterranean diet was evaluated using the PREvención con DIeta MEDiterránea (PREDIMED questionnaire. PhA was calculated by BIA phase-sensitive system (50 kHz BIA 101 RJL, Akern Bioresearch, Florence, Italy Akern. In both sexes, at ROC analysis a PREDIMED score ≥ 6 predicted a PhA beyond the median value. At the multivariate analysis, among PREDIMED score, age, and BMI, the PREDIMED score was the major determinant of PhA, explaining 44.5% and 47.3% of PhA variability, in males and females respectively (p < 0.001. A novel association was reported between the adherence to the Mediterranean diet and PhA, independently of sex, age, and body weight. This association uncovered a new potential benefit of the Mediterranean diet on health outcomes, as in both sexes higher adherence to the Mediterranean diet was associated to larger PhAs, as expression of cell membrane integrity.

    Full Text Available Abstract Background As weight gain is one of the most frequently cited reasons for not using and for discontinuing hormonal contraceptives, in an open-label, single-arm, multicentre clinical study we evaluated the effect of the ethinylestradiol/norelgestromin contraceptive patch (EVRA, Janssen-Cilag International, Belgium on body composition using bioelectrical impedance analysis (BIA. Methods Body weight and impedance vector components (resistance (R and reactance (Xc, at 50 kHz frequency, Akern-RJL Systems analyzer were recorded before entry, after 1, 3 and 6 months in 182 Italian healthy women aged 29 yr (18 to 45, and with BMI 21.8 kg/m2 (16 to 31. Total body water (TBW was estimated with a BIA regression equation. Vector BIA was performed with the RXc mean graph method and the Hotelling's T2 test for paired and unpaired data. Results After 6 months body weight increased by 0.64 kg (1.1% and TBW increased by 0.51 L (1.7%. The pattern of impedance vector displacement indicated a small increase in soft tissue hydration (interstitial gel fluid. Body composition changes did not significantly differ among groups of previous contraceptive methods. Arterial blood pressure did not significantly change over time. Conclusion After 6 months of treatment with the ethinylestradiol/norelgestromin contraceptive patch we found a minimal, clinically not relevant, increase in body weight less than 1 kg that could be attributed to an adaptive interstitial gel hydration. This fluctuation is physiological as confirmed by the lack of any effect on blood pressure. This could be useful in increasing women's choice, acceptability and compliance of the ethinylestradiol/norelgestromin contraceptive patch.

    combines MODIS Terra satellite and Aqua, C005 data collection. The AOD at 550 nm in the C005 collection data of MODIS have been proven to be more accurate than the previous version in assessment studies using AERONET data. The need of daily information of aerosol attenuation parameters has been clearly observed in places where aerosol optical depth variability is high (as the case of India). In addition, the sensitivity to the clear sky model used in the methodology has been also briefly analyzed, but a deeper analysis would require more extensive ground measurement. The sensitivity results show that, as expected, DNI estimations are much more sensible to the atmospheric attenuation input than GHI. The GHI response to the atmospheric aerosol loading is modulated by the positive feedback of the diffuse component and by the angular projection. When comparing the sensitivity of satellite estimations in Spain and India, it is pointed out than the higher aerosol loading and dynamics that normally occurs over India cause higher variability of both GHI and DNI satellite calculations.

    The problem of asbestos in road surfaces is handled differently in the individual Federal States of Germany. Currently, only in Lower Saxony and partly in Hamburg and Schleswig-Holstein the road surfaces were analysed according to the existence of asbestos with respect to the regulation TRGS 517/BIA 7487. The remaining Federal States assume fundamentally that asphalt may contain asbestos. Protective measures such as milling of road surfaces are applied. Te most Federal States do not supply information on the handling of TRGD 517 when building roads.

    Full Text Available Fluid overload is a well-known predictor of mortality in patients with acute kidney injury (AKI. Multifrequency bioimpedance analysis (MF-BIA is a promising tool for quantifying volume status. However, few studies have analyzed the effect of MF-BIA-defined volume status on the mortality of critically ill patients with AKI. This retrospective medical research study aimed to investigate this issue.We retrospectively reviewed the medical records of patients with AKI who underwent continuous veno-venous hemodiafiltration (CVVHDF from Jan. 2013 to Feb. 2014. Female patients were excluded to control for sex-based differences. Volume status was measured using MF-BIA (Inbody S20, Seoul, Korea at the time of CVVHDF initiation, and volume parameters were adjusted with height squared (H2. Binary logistic regression analyses were performed to test independent factors for prediction of in-hospital mortality.A total of 208 male patients were included in this study. The mean age was 65.19±12.90 years. During the mean ICU stay of 18.29±27.48 days, 40.4% of the patients died. The in-hospital mortality rate increased with increasing total body water (TBW/H2 quartile. In the multivariable analyses, increased TBW/H2 (OR 1.312(1.009-1.705, p=0.043 and having lower serum albumin (OR 0.564(0.346-0.919, p=0.022 were independently associated with higher in-hospital mortality. When the intracellular water (ICW/H2 or extracellular water (ECW/H2 was adjusted instead of the TBW/H2, only excess ICW/H2 was independently associated with increased mortality (OR 1.561(1.012-2.408, p=0.044.MF-BIA-defined excess TBW/H2 and ICW/H2 are independently associated with higher in-hospital mortality in male patients with AKI undergoing CVVHDF.

    Objectives To assess the clinical value of ultrasonography (US) and bioelectrical impedance analysis (BIA) in analyzing abdominal fat contents of obese children and adolescents through comparison with MRI. A correlation with other obese related metabolic parameters was conducted. Methods Ninety 7-17-y-old obese children and adolescents (60 boys and 30 girls with mean age of 9.6 ± 2.9 y and mean BMI of 24.5 ± 4.5 kg/m2) were recruited. Metabolic parameters were measured, and insulin resistance was estimated according to homeostasis model assess-ment (HOMA-IR). On the same day abdomen subcutaneous fat thickness (SFTUS) was measured by US. Body fat mass (FMBIA) and abdominal visceral fat area (VFABIA) were analyzed by bioelectrical impedance analysis (BIA). After obtaining informed consent, abdominal MRI was performed in 20 subjects. Each section of umbilicus level was analyzed by image threshold value segmentation using SigmaScan Pro 5 and abdominal subcutaneous fat area (SFAMRI) and visceral fat area (VFAMRI) were calculated. Results (1) A strong positive association was found between SFTUS and SFAMRI (P< 0.05), VFABIA and VFAMRI (P < 0.01) respectively. (2) FMBIA and SFAMRI, VFAMRI, SFTUS also showed significant correlations (P < 0.05). (3) VFAMRI showed extremely significant positive correlations with TG, Insulin,C-peptide and HOMA-IR (P < 0.01 ) ; SFAMRI was also correlated positively with them (P < 0.05). (4) SFTUS was correlated positively with UA (uric acid), Insulin, 2HIns (insulin measured at 2 hours after meal), C-peptide,2HC-peptide (C-peptide measured at 2 hours after meal) and HOMA-IR (P < 0.01). (5) VFABIA was correlated significant positively with UA, insulin, TG, 2HIns and HOMA-IR. FMBIA showed positive correlation with UA, Insulin,2HIns, C-peptide, 2HC-peptide and HOMA-IR. Conclusions abdominal subcutaneous and visceral fat of obese children and adolescents evaluated by US and BIA are correlated well with those assessed by MRI, and also correlated
