    2007-01-01

    This paper constructs the probability model of Gunther generator at first, and the finite dimension union distribution of the output sequence is presented. The result shows that the output sequence is an independent and uniformly distributed 0,1 random variable sequence.It gives the theoretical foundation about why Gunther generator can avoid the statistic weakness of the output sequence of stop-and-go generator, and analyzes the coincidence between output sequence and input sequences of Gunther generator. The conclusions of this paper would offer theoretical references for designers and analyzers of clock-controlled generators.

    To evaluate of the medium-term integrity, efficacy, and complication rate associated with the Gunther Tulip vena cava filter. A retrospective study was performed of 369 consecutive patients who had infrarenal Gunther Tulip inferior vena cava filters placed over a 5-year period. The mean patient age was 61.8 years, and 59% were men. Venous thromboembolic disease and a contraindication to or complication of anticoagulation were the indications for filter placement in 86% of patients; 14% were placed for prophylaxis in patients with a mean of 2.3 risk factors. Follow-up was obtained by review of medical and radiologic records. Mean clinical follow-up was 780 days. New or recurrent pulmonary embolus occurred in 12 patients (3.3%). New or recurrent deep-vein thrombosis occurred in 53 patients (14.4%). There were no symptomatic fractures, migrations, or caval perforations. Imaging follow-up in 287 patients (77.8%) at a mean of 731 days revealed a single (0.3%) asymptomatic fracture, migration greater than 2 cm in 36 patients (12.5%), and no case of embolization. Of 122 patients with CT scans, asymptomatic perforations were identified in 53 patients (43.4%) at a mean 757 days. The Gunther Tulip filter was safe and effective at 2-year follow-up. Complication rates were similar to those reported for permanent inferior vena cava filters.

    Inferior vena cava (IVC) filters are widely used to decrease the risk of pulmonary embolism in patients with contraindications to anticoagulation. Complications include local hematoma, access site deep venous thrombosis (DVT), filter migration and embolization, leg penetration through the IVC wall, IVC occlusion, and filter fracture with embolization. Other rare complications include leg penetration into adjacent organs including duodenum and ureter. Lumbar artery pseudoaneurysms are rare and may be spontaneous, iatrogenic, or traumatic. To date, there have been 3 case reports of lumbar artery pseudoaneurysms caused by IVC filters. We present an additional case of a lumbar artery pseudoaneurysm caused by a Gunther Tulip IVC filter treated successfully with selective embolization.

    Success rates vary for the retrieval of inferior vena cava filters (IVCFs). The optimal retrieval time and factors influencing retrieval success remain unproven. This study aims to determine optimal time and evaluate factors related to successful IVCF retrieval. An institutional prospectively maintained database was reviewed for all IVCF retrieval attempts from 2006 to 2012. Patient demographics, comorbidities, indications for procedure, placement technique, IVCF type, presence of angulation, and time to retrieval were evaluated with respect to success or failure of retrieval. Statistical analyses (t-test, χ(2), correlations, and Kaplan-Meier plots) were performed comparing successful and unsuccessful retrievals. Of 121 attempted IVCF retrievals, 92 (76%) were successful and 29 (24%) were unsuccessful. There were no significant differences between the successful and unsuccessful attempts in terms of patient demographics, comorbidities, indications for procedure, placement technique, or IVCF type, which included 93 Celect (77%) and 28 Gunther Tulip (23%). Time since IVCF placement was significantly different (P = .025) between the successful and unsuccessful retrieval groups (medians were 105 [7-368] and 162 [43-379] days, respectively). Time since IVCF placement greater than 117 days correlated significantly with unsuccessful IVCF retrieval (R = 0.218; P = .017; odds ratio, 2.88; P = .02). Angulation greater than 20 degrees on anteroposterior radiograph was noted in seven of 29 (24%) unsuccessful retrievals compared with seven of 92 (8%) successful retrievals and was significant (P = .012). Cook Gunther Tulip and Celect IVCF retrieval is most likely to be successful within 3 to 4 months of placement. Unsuccessful retrieval attempts are more likely to occur when IVCF position is angulated. Copyright © 2014 Society for Vascular Surgery. Published by Elsevier Inc. All rights reserved.

    Retrieval of a Gunther tulip vena cava filter implanted in a patient with inferior vena cava and right common iliac vein thrombosis was attempted by the standard method. Because the filter was tilted, the hook became attached to the vena cava wall and could not be snared. During attempts at removal by an alternative method, the filter migrated toward the right atrium. However, it was finally successfully removed.

    The aim of our study was to assess our experience with the retrievable Gunther Tulip (GT) inferior vena cava (IVC) filter, with regard to its insertion, efficacy, ease of placement and retrieval, and associated complications. Between November 2001 and October 2005, 322 GT filters were placed in 317 patients. Insertion indications included the following: pulmonary embolus (PE) prophylaxis in trauma patients (n = 232), PE prophylaxis in perioperative patients (n = 27), PE prophylaxis in moribund intensive care unit patients (n = 22), recent PE (n = 48), extensive deep venous thrombosis (n = 66), contraindication to anticoagulation (n = 63), anticoagulation complication (n = 8) and deep venous thrombosis with failed anticoagulation (n = 8). Some patients had more than one indication for caval filter placement. Two hundred and five attempted retrievals have been carried out, with 15 failures. Our successful retrieval rate is 92%. Nineteen filters were originally inserted permanently. There have been three minor complications associated with insertion and five with retrieval. The mean time from filter insertion to attempted retrieval was 76.95 days. The ideal filter implantation time gives the patient the benefit of PE protection, while avoiding the long-term risks associated with caval filters. Although GT retrieval times have lengthened considerably, our data suggest that this is at the expense of successful retrieval rates.

    A Gunther tulip vena cava filter was implanted in a patient with pulmonary embolism from deep venous thrombosis. The filter became unnecessary after therapy. However, retrieval by the standard method employing a vascular sheath placed via the transjugular approach in combination with a snare device was impossible. A thrombus occupying the apical hook made it difficult to snare the hook, also one filter leg was incorporated into the inferior vena cava wall. Therefore we modified an existing method to withdraw the filter. As the first step, the filter cone was snared using the snare-over-guide wire loop technique, and the cephalad site of the filter was introduced into the sheath. Then, a 12-French sheath was advanced from the femoral vein and, using a pusher, the distal legs of the filter were pushed, which resulted the filter leg that was incorporated into the inferior vena cava wall became detached. Finally the filter was successfully retrieved.

    Symptomatic penetration of the inferior vena cava (IVC) wall reportedly occurs in 0.3% of patients in whom a filter has been implanted, and it causes injury to the adjacent structures (Bogue et al. in Pediatr Radiol 39(10):1110-1113, 1; Brzezinski et al. in Burns 32(5):640-643, 2). We succeeded in the endovascular repair of perforation of the IVC wall occurring during the retrieval of a penetrated Gunther tulip vena cava filter (Cook, Bjaeverskov, Denmark) after long-term implantation.

  12. Hair breakage during combing. III. The effects of bleaching and conditioning on short and long segment breakage by wet and dry combing of tresses.

    2007-01-01

    A recent publication (1), provided evidence for two types of hair breakage during combing, short segment breakage (approximately less than 1.27 cm) and longer segment breakage. We have confirmed these results and refined the separation distance between short and long segment breakage at about 2.54 cm. Furthermore, chemical bleaching increased both short and long segment breakage while a commercial hair conditioner decreased both types of breakage. Whether the hair is chemically bleached or conditioned, for dry combing, short segment breakage increases with increasing comb strokes, that is, short segment breakage increases as combing damages the ends of the hair, however, long segment breakage does not increase with increasing comb strokes. Wet combing provided a decrease in short segment breakage and an increase in long segment breaks, but no increase in breakage with increasing comb strokes. Mechanical combing of tresses shows similar results qualitatively, however the variance was too large and adjustments need to be made to provide for a larger number of broken hairs to bring the mechanical and hand combing results in line. For dry combing, as the comb descends through the hair, hairs above it are made parallel and those beneath are either made parallel or knot by, hairs looping around other hairs or hairs looping around comb teeth and other hairs several cm between the comb and the hair tips. As the comb advances through the looped/knotted hairs long breaks occur or as the comb descends near the tips wrapped ends can result. End wrapping by inertia & possibly static charge produces short segment breaks which are more severe if the hair is cut at 90 degrees versus a tapered cut. For wet combing, clumping of hairs by a capillary action produces fewer short segment breaks, by reducing end wrapping: however, crossed hair interactions occur & because of higher friction more severe snags arise higher up in the tress, and lower hair breaking load due to plasticization

Méthodes Nous avons réalisé une étude transversale prospective d’Octobre 2014 à Janvier 2015. La collecte des données était faite à l’aide d’un questionnaire court auprès de l’opérateur du transfert. Principaux paramètres: moyen de transport, motif du transfert, délai du transfert, nombre de décours (itinéraire avant l’admission) prévalence de l’hypothermie, taux de mortalité néonatale. Résultats Nous avons enregistré 73 transferts durant la période Près de 1/5 (22%) étaient nés au sein du district de santé de la structure de référence. Les nouveau-nés référés venaient de structures tertiaires dans 24/73 (33%). Le principal motif de transfert était la grande prématurité (40%) suivi de l’asphyxie néonatale (26%). Le transfert était médicalisé dans 5/73 (7%) des cas et infirmier interhospitalier dans 10/73 (13,6%) des cas. Le délai moyen de transfert était de 17 heures, 60% avaient été transférés dans les 6 premières heures de vie et 22% (16/73) dans les deux heures. Pour plus de la moitié des nouveau-nés, un détour dans une autre structure avait été réalisé avant l’admission. L’hypothermie (température centrale inférieure à 36°) à l’arrivée était notée dans 20% des cas. 15/73(20,5%) des nouveau-nés transférés sont décédés. la température moyenne à l’arrivée des nouveau-nés décédés étaient de 35°5C vs 37°C chez les non-décédés (p=0,006). Le pourcentage de nouveau-nés ayant subi plus de 2 détours était de 57% chez les décédés versus 30% chez les non-décédés (p=0,02). Conclusion A Yaoundé, les conditions de transferts des nouveau-nés précaires grèvent le pronostic néonatal immédiat à cause d’un itinéraire erratique qui majore le risque d’hypothermie et de d

The deficiency of dietary vitamin C can result in the damage on fish. The study on the deficiency symptom and the sensitive indicator of vitamin C could provide useful information for fish feed industry. This experiment was conducted to investigate the effects of dietary Vitamin C levels on growth performance, immune and physiological responses in Chinese longsnout catfish (Leiocassis longirostris Gunther) , which is an high value aquaculture fish in China. Three practical diets containing 38,364 and 630mg/kg vitamin C were fed to Chinese longsnout catfish (23. 19 ± 0. 58g) for 8 months. Vitamin C was used in the form of L-ascorbyl-2-polyphosphate. The results indicated that the Chinese longsnout catfish in 38mg/kg vitamin C groups showed typical vitamin C deficiency symptom: skin color turning darker, spinal deformities and scoliosis, erosion of fins, anaemia. SGR and the serum lysozyme activities decreased significantly (p < 0. 05), the hepatic SOD activities and MDA contents increased significantly (p < 0. 05). There was no significant difference in serum cortisol

    High performance composites reinforced by woven or braided fabrics have several different applications in various fields such as in the aerospace, automobile and marine industry. This research project was carried out at the Ecole Polytechnique de Montreal in collaboration with an industrial sponsor, the company Composites Atlantic Ltd. Composite springs often represent an interesting alternative, given the reduction in weight that they allow with equal mechanical performance compared to metallic springs. Their good resistance to fatigue and corrosion bring additional benefits in several industrial applications. Moreover, the use of the composites increases safety by avoiding the risks of brutal rupture because of the low propagation velocity of cracks in this type of material. Lastly, in electrotechnics, another significant advantage comes into play because of the electrical insulation capability of composite springs. Few research results can be found on composite springs in the scientific literature. The first part of this thesis studies the problems connected with the design of composite springs. The results are promising, because it was confirmed that composite springs can be devised with the same mechanical performance in term of stiffness as metallic ones. Two solutions were found to replace the metallic springs of the suspension of a four wheel drive: the first spring was in carbon-epoxy, and the second one in glass-epoxy. In the second part, software was developed in order to devise a new approach to predict the mechanical properties of woven or braided composites. This work shows how an inverse method based on plate laminate theory allows creating, from experimental results on braided composites, a virtual basic ply that includes the effect of fiber architecture (undulation and braiding angle). Using this model, the properties of the composite can be predicted for any braid angle. The comparison with the experimental results shows a good correlation with numerical predictions. In third part, an experimental study on creep was conducted on composite plates manufactured with the same constitutive materials as the composite springs. Creep tests in three point bending were carried out with Q800 DMA machine. The results showed that creep behavior depends primarily on the polymer matrix. However, rigidity is a function of the fiber-matrix mixture. The braiding angle of 35° corresponds to a characteristic threshold for braided composites: beyond this value, rigidity falls in a creep test at a temperature higher than Tg. It represents also a critical angle in bending or in tensile tests. Above 35°, the failure mode of the composite goes from fragile (rupture of fibers) to a mixed mode, in which the polymer matrix comes also into play with fibers. A good stability was observed for the composites with a braiding angle lower than +/- 35° or higher than +/-60°. Long-term tests were also carried out for two braided composites at +/- 45° and +/- 55° in order to check the predictive model of the DMA. The shift factors obtained from the short and long term tests are roughly equal. This thesis has set the ground for the future development on industrial applications of composite springs. The design software predicts the mechanical effectiveness of helical composite springs. The software developed to predict the elastic properties of braided composites accelerates the preparation of characterization results for the design stage. This numerical tool could be generalized for other fiber architectures. It represents a practical tool for further investigations. Finally, the study on creep, although preliminary, provides a first evaluation of the life cycle of composite springs. It would be interesting to proceed now to the design of a first industrial application.

    Rapid prediction of annual ring density of Paulownia elongate standing trees using near infrared spectroscopy was studied. It was non-destructive to collect the samples for trees, that is, the wood cores 5 mm in diameter were unthreaded at the breast height of standing trees instead of fallen trees. Then the spectra data were collected by autoscan method of NIR. The annual ring density was determined by mercury immersion. And the models were made and analyzed by the partial least square (PLS) and full cross validation in the 350-2 500 nm wavelength range. The results showed that high coefficients were obtained between the annual ring and the NIR fitted data. The correlation coefficient of prediction model was 0.88 and 0.91 in the middle diameter and bigger diameter, respectively. Moreover, high coefficients of correlation were also obtained between annual ring density laboratory-determined and the NIR fitted data in the middle diameter of Paulownia elongate standing trees, the correlation coefficient of calibration model and prediction model were 0.90 and 0.83, and the standard errors of calibration (SEC) and standard errors of prediction(SEP) were 0.012 and 0.016, respectively. The method can simply, rapidly and non-destructively estimate the annual ring density of the Paulownia elongate standing trees close to the cutting age.

    Severe tilting of Günther Tulip filter (GTF) may be associated with difficulty in retrieval. To determine if an introducer curving technique of GTF can decrease the tilting degree of GTF in a caval model. The model was constructed by placing Dacron grafts in bifurcated glass tubes. The study included three groups: Right Straight Group (G(1)), Left Straight Group (G(2)), and Left Curved Group (G(3)). In G(3), a 10-20° angle was curved on the metal introducer before insertion to decrease the angle between inferior vena cava axes and metal introducer (A(CM)). Before GTF was released, the distance between the caval right wall and the apical hook (D(CH1)), and A(CM) were measured. The tilt angle of GTF (A(CF)) was also measured. In G(1), GTF apex tended to center compared to G(2) (59% vs. 36%, P < 0.01). In G(3), GTF apex tended to center compared to G(2) (71% vs. 36%, P < 0.01). The differences of A(CF) between G(1) and G(2) (2.66 ± 1.80 vs. 4.13 ± 2.07, P < 0.01) and between G(2) and G(3) (4.13 ± 2.07 vs. 2.39 ± 1.79, P < 0.01) were statistically significant. There were significant positive correlations between A(CM) and A(CF), whereas significant negative correlations were detected between D(CH1) and A(CF) in each group. The oblique course of GTF delivery system relative to the axis of the cava causes filter tilt, and thus, curving the introducer prior to its introduction helps to reduce the filter tilt. We recommend a clinical study to determine whether the introducer curving technique improves filter centering and its retrievability.

    To determine whether the introducer curving technique is useful in decreasing the degree of tilting of transfemoral Tulip filters. The study sample group consisted of 108 patients with deep vein thrombosis who were enrolled and planned to undergo thrombolysis, and who accepted transfemoral Tulip filter insertion procedure. The patients were randomly divided into Group C and Group T. The introducer curving technique was Adopted in Group T. The post-implantation filter tilting angle (ACF) was measured in an anteroposterior projection. The retrieval hook adhering to the vascular wall was measured via tangential cavogram during retrieval. The overall average ACF was 5.8 {+-} 4.14 degrees. In Group C, the average ACF was 7.1 {+-} 4.52 degrees. In Group T, the average ACF was 4.4 {+-} 3.20 degrees. The groups displayed a statistically significant difference (t = 3.573, p = 0.001) in ACF. Additionally, the difference of ACF between the left and right approaches turned out to be statistically significant (7.1 {+-} 4.59 vs. 5.1 {+-} 3.82, t = 2.301, p = 0.023). The proportion of severe tilt (ACF {>=} 10 degree) in Group T was significantly lower than that in Group C (9.3% vs. 24.1%, X{sup 2} = 4.267, p = 0.039). Between the groups, the difference in the rate of the retrieval hook adhering to the vascular wall was also statistically significant (2.9% vs. 24.2%, X{sup 2} = 5.030, p = 0.025). The introducer curving technique appears to minimize the incidence and extent of transfemoral Tulip filter tilting.

    Tilting of a deployed filter in the inferior vena cava (IVC) is a particular kind of periprocedural complication and this can reduce the filter's clot-trapping ability and increase the occlusion of the IVC at a later period. The authors report here on a case of spontaneous tilting of an inferior vena caval filter that was associated with thrombosis in the IVC within 2 weeks of the initially successful placement of the filter without tilting.

    Full Text Available Oligosarcus argenteus belongs to the Acestrorhynchinae subfamily, being restricted to South America, and found in several Brazilian hydrographic basins, in lotic and lentic environments, where they are able to reproduce. With the purpose of studying the reproductive biology of the males from this species, many morphological parameters were analyzed during a 24 month period, as well as characterizing the different testicular maturation stages. A maturity scale, with three stages (I - Initial Maturing, II - Intermediate Maturing, III - Final Maturing was proposed for the adult males of Oligosarcus argenteus. The reproductive period was established by the bimonthly frequency of spermatogenesis and by the gonadal maturation stages.Oligosarcus argenteus é uma espécie pertencente à subfamília Acestrorhynchinae, restrita à América do Sul, sendo comumente encontrada nas várias bacias hidrográficas brasileiras, em ambientes lóticos e lênticos, onde se reproduzem.

    We investigated the effect of prolonged immobilisation of six and nine months duration on the morphology and antioxidant biochemistry of skeletal muscles in the amphibian aestivator Cyclorana alboguttata. We hypothesised that, in the event of atrophy occurring during aestivation, larger jumping muscles were more likely to be preserved over smaller non-jumping muscles. Whole muscle mass (g), muscle cross-sectional area (CSA) (microm(2)), water content (%) and myofibre number (per mm(2)) remained unchanged in the cruralis muscle after six to nine months of aestivation; however, myofibre area (microm(2)) was significantly reduced. Whole muscle mass, water content, myofibre number and myofibre CSA remained unchanged in the gastrocnemius muscle after six to nine months of aestivation. However, iliofibularis dry muscle mass, whole muscle CSA and myofibre CSA was significantly reduced during aestivation. Similarly, sartorius dry muscle mass, water content and whole muscle CSA was significantly reduced during aestivation. Endogenous antioxidants were maintained at control levels throughout aestivation in all four muscles. The results suggest changes to muscle morphology during aestivation may occur when lipid reserves have been depleted and protein becomes the primary fuel substrate for preserving basal metabolic processes. Muscle atrophy as a result of this protein catabolism may be correlated with locomotor function, with smaller non-jumping muscles preferentially used as a protein source during fasting over larger jumping muscles. Higher levels of endogenous antioxidants in the jumping muscles may confer a protective advantage against oxidative damage during aestivation; however, it is not clear whether they play a role during aestivation or upon resumption of normal metabolic activity.

    Full Text Available Many chemicals have been used as anaesthetics in fish farms and fish biology laboratories to keep the fish immobilized during handling procedures and to prevent accidents and animal stress. In Brazil, tricaine methane sulfonate (MS 222, quinaldine sulfate, benzocaine, and phenoxyethanol are the most common fish anaesthetics used to prevent fish stress during handling, but many side effects such as body and gill irritations, corneal damage and general risks of intoxication have been reported. Clove oil is a natural product proposed as an alternative fish anaesthetic by many researchers and it has been used in many countries with great economic advantages and no apparent toxic properties. In this work, we assessed the suitability of clove oil to anaesthetize matrinxã. Sixty-three juveniles of matrinxã were exposed to seven anaesthetic batches of clove oil (pharmaceutical grade namely 18, 20, 30, 40, 50, 60, and 70 mg/L. The times to reach total loss of equilibrium and to recover the upright position were measured. Clove oil concentration about 40 mg/L was enough to anaesthetize the fish in approximately one minute and the recovery time was independent in regard to anaesthetic concentration.Diversos produtos químicos têm sido empregados como anestésicos para peixes nas estações de piscicultura e laboratórios de biologia de peixes para a devida imobilização dos organismos, afim de se prevenir acidentes e ferimentos na superfície do corpo dos próprios peixes, que podem ficar susceptíveis a patógenos e taxas altas de mortalidade. A tricaina metano sulfonato (MS 222, a quinaldina, a benzocaina e o phenoxyethanol têm sido amplamente utilizados no Brasil, mas alguns efeitos colaterais são observados como perda de muco, irritação nas brânquias e olhos, e também alguns incômodos aos trabalhadores como a necessidade do uso de luvas. Dessa forma, o óleo de cravo é proposto como um anestésico alternativo por ser um produto natural de custo acessível e sem riscos aparentes de intoxicações. No presente trabalho estudamos a possibilidade do uso do óleo de cravo como anestésico para juvenis de matrinxã, utilizando-se 63 peixes, expondo-os a banhos anestésicos nas concentrações de 18, 20, 30, 40, 50, 60 e 60 mg/L, de forma que foram mensurados os tempos necessários para que os peixes atingissem a perda total de equilíbrio e a incapacidade de retornar a posição normal de nado. A concentração de 40 mg/L foi suficiente para anestesiar juvenis de matrinxã em aproximadamente 1 minuto, sendo a recuperação independente da concentração do anestésico.

    Full Text Available Hyper motility is a negative factor in fish handling procedures due to the risks of damages to the animals. Chemicals are widely used to anesthetize fish during biometry and many other handling procedures. 2-Phenoxyethanol is largely employed, but many studies are necessary about tropical fish responses. The present research evaluated the anesthesia induction time for juvenile matrinxã submitted to eight different levels of 2-phenoxyethanol. The range of 2-phenoxyethanol concentration was 250-600mg liter-1. Induction time of anesthesia decreased as a function of 2-phenoxyethanol concentrations. Fish were safely anesthetized approximately after one minute of exposure to 2-phenoxyethanol batches in concentrations above 400mg/liter, and the recover period was about one minute for all anesthetic concentrations. 2-Phenoxyethanol is a safe anesthetic for juvenile matrinxã even in exposures up to 600mg liter-1 being recommended for many field procedures of fish handling.

  17. Feeding dynamics and ecomorphology of Oligosarcus jenynsii (Gunther, 1864 and Oligosarcus robustus (Menezes, 1969 in the Lagoa Fortaleza, southern Brazil

    Full Text Available Oligosarcus jenynsii and Oligosarcus robustus are fishes of Characidae family that occur in Rio Grande do Sul, Uruguay and northern Argentina. This work purported to study the feeding dynamics (repletion and hepatosomatic indexes and condition factor over time, and to investigate the coexistence of these two species by evaluating the partition of resources using qualitative and quantitative analyses of diet, temporal and spatial segregation throughout the water column and some ecomorphological aspects of the species in the Lagoa Fortaleza. Specimens were sampled monthly, from May 2000 to April 2001 during 24 h/month, using stationary gill nets of different mesh sizes. The records of each individual included total and standard length; total, stomach and liver weight; sex and stomach repletion. The variation of the mean values of repletion index and relative frequencies of stomach repletion stages indicate that O. jenynsii and O. robustus do not present seasonal differences in feeding intensity. The hepatosomatic index shows an allocation of energy to the liver during every period except reproduction, when part of the energy is used for gonad maturation. The estimated condition factor for both species reveals an increase in the reproductive period, evidencing the influence of gonads upon the condition of the fish. The diet analysis revealed that O. robustus is piscivorous, whereas O. jenynsii is a generalist carnivore, tending to piscivory as well. The active period of O. robustus is more concentrated at sunrise and sunset, whereas O. jenynsii is continually active, a characteristic related to hunting for prey. The ecomorphological analysis revealed differences between the two species in the dimensions of the mouth. Evidence suggests that the species coexist, sharing food sources, differing in oral morphology but ingesting similar prey, possibly because food is not a limiting factor in the environment.

    Full Text Available A first attempt to regulate the fishing activity while preserving the species and its habitats is presented for Hule lake. We intensively sampled the "guapote" between March 1996 and April 1997 using monofilament gill nets and a floating line, collecting 421 individuals. P. dovii biomass was relatively low; this species had a long life cycle (8-10 years and the growth oscillation was low (C=0.3. Maximum life expectation was estimated at 12 years and the point of minimum growth coincided with the spawning that takes place between November and December. After spawning, P. dovii take around seven months to reach recruitment size (54.6 mm. The length of first maturation was 134 mm Lt, which indicates that this species is viable for reproduction soon after leaving the protection zones around the lagoon. "Guapote" sport fishing in the Hule lake is in equilibrium, the renewal rate is 80%. An increment in the actual fishery effort is not recommended, since it could seriously affect the natural renewal capacity of the stock.Un primer intento para regular la actividad de la pesca deportiva para el guapote lagunero, Parachromis dovii mediante los resultados de un programa de evaluación del recurso y del estudio de la dinámica poblacional de esta especie se presenta.

Luego del desove, P. dovii permanece en las áreas protegidas cerca de 7 meses hasta alcanzar la talla de reclutamiento (54.6 mm Lt. La longitud de primera maduración fue de 134 mm Lt, lo que indica que esta especie es apta para reproducirse poco tiempo después de haber abandonado las áreas de protección, ubicadas alrededor de la laguna. También se describen algunos aspectos de su biología. La pesca deportiva del guapote en la laguna Hule mantiene aún a la población en equilibrio, la tasa de renovación natural se estima en 80%, por lo que no se recomienda permitir un incremento en los niveles actuales de esfuerzo pesquero, dado que esto afectaría seriamente la capacidad de renovación natural de P. dovii.

    Prolonged immobilisation or unloading of skeletal muscle causes muscle disuse atrophy, which is characterised by a reduction in muscle cross-sectional area and compromised locomotory function. Animals that enter seasonal dormancy, such as hibernators and aestivators, provide an interesting model for investigating atrophy associated with disuse. Previous research on the amphibian aestivator Cyclorana alboguttata (Günther 1867) demonstrated an absence of muscle disuse atrophy after 3 months of aestivation, as measured by gastrocnemius muscle contractile properties and locomotor performance. In this study, we aimed to investigate the effect of aestivation on iliofibularis and sartorius muscle morphology and contractile function of C. alboguttata over a longer, more ecologically relevant time-frame of 9 months. We found that whole muscle mass, muscle cross-sectional area, fibre number and proportions of fibre types remained unchanged after prolonged disuse. There was a significant reduction in iliofibularis fibre cross-sectional area (declined by 36% for oxidative fibre area and 39% for glycolytic fibre area) and sartorius fibre density (declined by 44%). Prolonged aestivation had little effect on the isometric properties of the skeletal muscle of C. alboguttata. There was a significant reduction in the isometric contraction times of the relatively slow-twitch iliofibularis muscle, suggesting that the muscle was becoming slower after 9 months of aestivation (time to peak twitch increased by 25%, time from peak twitch to half relaxation increased by 34% and time from last stimulus to half tetanus relation increased by 20%). However, the results of the work-loop analysis clearly demonstrate that, despite changes to muscle morphology and isometric kinetics, the overall contractile performance and power output levels of muscles from 9-month aestivating C. alboguttata are maintained at control levels.

    Objective:To report the morphological details of the two species ofProcamallanus with scanning electron microscopy. Methods: To gain insights into the phenology ofProcamallanus spp., scanning electron microscopy descriptions of male and female parasites along with attendant histopathological consequences to the hosts species were undertaken. The two species were obtained from the intestines of the freshwater fish,Parachanna obscura. Parasites were fixed in 2.5% glutaldehyde and postfixed in osmium tetraoxide, sputter-coated and examined with the electron microscope. Results: Nominal parasitic species ofProcamallanuscould be distinguished with spiral thickenings in front of the buccal capsule. The male specimens of the parasite (n = 213) were recorded in a prevalence of 12.7% while the female specimens (n = 68) were recorded in a prevalence of 20.5%. An overall prevalence of 14.6% was obtained in the fish species. The twoProcamallanus species differed from the described species of the genusProcamallanus (Spiracamallanus) with having the posterior end not ventrally bent, tail not short but elongate and straight bending slightly with no spikes, inner depression at the posterior region, excretory pore near the posterior end, wider cephalic region with an inner sieve-like compartment, longitudinal cephalic papillae, papillae of external circles distinctly larger and lateral cuticular extensions. These male and female species ofProcamallanus exhibited novel morphometrics descriptions in the number of preanal and postanal papillae and different body and shape relationship. The histopathological changes seen in the host included hyperplasia of intestinal villi, mucosal hypercellularity of lamina propria and calcification of intestinal mucosa. Conclusions: This is the first scanning electron microscopy description of Procamallanus spp. in Nigeria describing the morphological details of the two species ofProcamallanus.

The fish were measured, weighed, dissected and the gonads were examined to separate the sex and to determine the stage of maturation. Histological studies were done for microscopic characterization of the gonads. The results indicated that H. affinis had a sexual proportion of 1:1; condition factor was inversely related to the gonadosomatic index during the reproductive phase; and the highest for both sexes was registered during the breeding season. Males and females showed four devolopmental stages of the gonads: immature, initial maturation, mature and spent. Absolute fecundity varied from 4400 to 6400 oocytes, with a mean of 5400. The species presents total spawing and the spawing season occurred in the months of May and June. The rainy season preceeded the occurrence of breeding flying fishes in the coastal waters of Caiçara do Norte.

Experimental catfish were subjected to 4conditions as follows: high temperature with 0.1% sodium chloride (HtWs, high temperature without 0.1% sodium chloride(HtW/s, low temperature with 0.1% sodium chloride (LtWs, and low temperature without 0.1% sodium chloride (LtW/s.Blood was taken from caudal vessel of anaesthetized fish to investigate blood clotting time, cortisol, glucose, osmolarity,Na+, K+ and Cl-. Ratios of Na+/K+, Na+/Cl- and Na+ + K+ / Cl- were also analyzed. In the short-term (1 day experiment, values ofall catfish blood parameters varied. These imply that catfish attempt to maintain internal balance, homeostasis. Osmolarityexhibited complete homeostasis in 2 h. From long-term (30 days exposure, non-significant means of Na+/Cl- ratio (HtWsand decreasing trend lines direction of blood clotting time (HtWs, LtW/s, LtWs indicated that 0.1% sodium chloride and/orLt helped stress reduction in catfish.

    Full Text Available Oitenta e uma macaubeiras (A. sclerocarpa foram derrubadas e dissecadas na periferia de Belo Horizonte, no período de abril/ 1979 a julho/1980. Foram capturados 463 exemplares de Rhodnius neglectus, com uma taxa de infestação das palmeiras de 60,5% e uma média de 9,45% triatomineos/palmeira positiva. O R. neglectus nesta região parece apresentar uma unica geração anual, com possibilidade de duas, sendo que o periodo de oviposição se relaciona com os meses quentes do ano, coincidindo com a predominância de formas jovens sobre os adultos. A observação sugere que a densidade populacional do R. neglectus no seu ecotopo natural possa estar relacionada com a disponibilidade de alimento e com a presença de predadores como o Telenomus sp., formigas, aranhas, hemipteros, escorpiões e pseudo-escorpiões. O indice global de infecção pelo Trypanosoma cruzi foi de 15,9%, indicando o R. neglectus como um importante vetor silvestre deste tripanosomatídeo cuja principal fonte e constituída por marsupiais. O R. neglectus na regiao encontra-se estreitamente associado a palmeira de macaúba, e as aves que as frequentam constituem sua principal fonte alimentar. As observações não sugerem o R.neglectus como uma espécie transmissora do T. cruzi ao homem nesta região.Eighty-one "macaubeiras" palm-trees (Acrocomia sclerocarpa from the periophery of Belo Horizonte city were cut down and dissected between April 1979 and July 1980. 60,5% of the trees were positive for R. neglectus and 463 specimens of this insect were collected, providing a mean rate of 9,45 individuals for positive palm-trees. R neglectus seems to present a single annual generation in this region, but evidence was obtained that two generations may occur. Its spawn period is related to the hot months of the year, when younger insects prevail over the adults. This observation suggests that higher population desities are related to better feeding conditions and to minor desities of specific prefators such as Telenomus sp., ants, spiders, hemipters, scorpions and pseudo scorpionidae. The Trypanosoma cruzi infection index was 15,9%, suggesting that R. neglectus is a very important vector of silvatic infections in the region. Marsupials are the main vertebrate source of T. cruzi infection. R. neglectus is strongly associated with palm-trees in the area, and with the various species of birds that haunt them. So far, there is no evidence suggesting R. neglectus to be an important vector of human Chagas' disease in the region.

    The difficulties of immigrant children at school have generally been studied with the emphasis either on their deficiencies or on the schemes which they devise to enable them to adapt. The study which is presented here, however, aims at a radically different approach by viewing the problem within the theoretical framework of transculturation and by examining the way in which the pupils themselves perceive the French school system. A study is made of the outcome of 101 interviews which were conducted in their mother tongue with Spanish- or Portuguese-speaking boys and girls aged between 10 and 17 years old. On the basis of statistical analysis by computer, indices were formulated with the intention of establishing (a) the relationship between the researcher and the subject during the interview; (b) the links between the subject as an individual and his/her peer-group (`me' — `us'); (c) his/her perception of `others'; and (d) the way in which he/she relates to his/her experience (as something to be positively accepted — or to be suffered; `active' or `passive'). Keywords illustrate and underline the difficulties encountered both by pupils and by the school to grasp the idea of time norms as a cultural shaping and to perceive how relative they are.

    Canopy-dwelling epiphytic plants have been well characterized in terms of the physiological and morphological traits permitting them to thrive in the absence of access to the soil. The ultimate purpose of this paper is to characterize the morphological and anatomical characteristics of major canopy-dwelling epiphytic plants and their host trees in the lower subtropical evergreen broad-leaved forest in the Southern China. Results showed epiphytic plants differed from host trees on leaf morphology and anatomy. Compared with host trees, epiphytic plants have smaller leaf area, larger specific leaf area (SLA), higher leaf water content, higher leaf thickness, higher leaf abaxial and adaxial epidermis thickness, lower stomatal density and stomata size for the uptake and restore of water and nutrients. Difference of leaf morphological and anatomical characters between epiphytes can be largely explained by changes of environmental factors such as photosynthetically active radiation (PAR), temperature and humidity within forest canopy. D. Chinensis and P. Serpens showed special characteristics with high leaf water contents, low stomatal density, thick spongy tissues and thin palisade tissues to adapt to their upper dwelling environment (high temperature, low air humidity and high PAR). F. Glaucescens and P. Hancei have large leaf area, thin leaf, and high stomata size in acclimatizing to the low temperature, high air humidity and low PAR.%选择南亚热带常绿阔叶林中具有代表性的4种林冠层附生植物:白背瓜馥木(Fissistigma glaucescens)、瓜子金(Dischidia chinensis)、蔓九节(Psychotria serpens)、山蒌(Piper hancei)及其主要宿主植物:厚壳桂(Cryptocarya chinensis)、荷木(Schimasuperba)、华润楠(Machilus chinensis)、锥栗(Castanopsis chinensis)为研究对象,对其叶片形态结构和解剖结构特征进行比较.研究结果表明:宿主植物与附生植物的叶片形态结构差异显著.相对于4种宿主植物,4种附生植物叶片无蜡被,比叶面积大,且具有含水量高,上下表皮厚度增加,气孔密度、气孔面积减少等特征,有利于叶片对水分和养分的吸收、贮存和利用.着生在林冠层不同部位的附生植物的叶片形态结构特征随着光合有效辐射、温度、湿度等微环境因子的变化表现出显著的差异:位于冠层顶部的瓜子金和蔓九节叶片小而厚,含水量高,气孔密度低且覆盖角质膜,更适应冠层顶部高温、低湿、高光照的环境;位于冠层下部的白背瓜馥木和山蒌叶片相对较薄,气孔面积较大,叶肉细胞分化明显,海绵组织排列松散,更适应冠层中下部低温、高湿、弱光照环境.变化的叶片结构是植物适应环境条件的重要表现.

    The Integrated Safety Analysis (ISA) methodology, developed by the Spanish Nuclear Safety council (CSN), has been applied to obtain the dynamic Event Trees (DETs) for full spectrum Loss of Coolant Accidents (LOCAs) of a Westinghouse 3-loop PWR plant. The purpose of this ISA application is to obtain the Damage Exceedance Frequency (DEF) for the LOCA Event Tree by taking into account the uncertainties in the break area and the operator actuation time needed to cool down and de pressurize reactor coolant system by means of steam generator. Simulations are performed with SCAIS, a software tool which includes a dynamic coupling with MAAP thermal hydraulic code. The results show the capability of the ISA methodology to obtain the DEF taking into account the time uncertainty in human actions. (Author)

    General potentials of UDD (ultra dispersive diamond), NbC, WC, W, WC-Co, ZrO2, Al2O3, Si3N4, Co, nanosized powders in determining structure and properties of composite electrodes and coatings deposited by electrospark alloying (ESA) and thermoreactive electrospark surface strengthening (TRESS) techniques were considered. It was shown that an addition of refractory compound nanosized powder to the electrode material positively effects microstructure and tribological characteristic of ESA-coatings. Nanoparticles incorporated in the coating on grains boundaries serve as a lubricant for friction pairs. Wear resistant W-C-Co coatings with a friction coefficient below 0.15 were deposited by TRESS using nanopowders of Co and W. Nano- or microstructural coatings on the base of cemented carbides can be formed, depending on pulse discharge energy and frequency. Examples of beneficial industrial application of the coatings strengthened by nanosized particles were presented.

  1. Hair Shaft Damage from Heat and Drying Time of Hair Dryer

    Science.gov (United States)

    Lee, Yoonhee; Kim, Youn-Duk; Hyun, Hye-Jin; Pi, Long-quan; Jin, Xinghai

    2011-01-01

    Background Hair dryers are commonly used and can cause hair damage such as roughness, dryness and loss of hair color. It is important to understand the best way to dry hair without causing damage. Objective The study assessed changes in the ultra-structure, morphology, moisture content, and color of hair after repeated shampooing and drying with a hair dryer at a range of temperatures. Methods A standardized drying time was used to completely dry each hair tress, and each tress was treated a total of 30 times. Air flow was set on the hair dryer. The tresses were divided into the following five test groups: (a) no treatment, (b) drying without using a hair dryer (room temperature, 20℃), (c) drying with a hair dryer for 60 seconds at a distance of 15 cm (47℃), (d) drying with a hair dryer for 30 seconds at a distance of 10 cm (61℃), (e) drying with a hair dryer for 15 seconds at a distance of 5 cm (95℃). Scanning and transmission electron microscopy (TEM) and lipid TEM were performed. Water content was analyzed by a halogen moisture analyzer and hair color was measured with a spectrophotometer. Results Hair surfaces tended to become more damaged as the temperature increased. No cortex damage was ever noted, suggesting that the surface of hair might play a role as a barrier to prevent cortex damage. Cell membrane complex was damaged only in the naturally dried group without hair dryer. Moisture content decreased in all treated groups compared to the untreated control group. However, the differences in moisture content among the groups were not statistically significant. Drying under the ambient and 95℃ conditions appeared to change hair color, especially into lightness, after just 10 treatments. Conclusion Although using a hair dryer causes more surface damage than natural drying, using a hair dryer at a distance of 15 cm with continuous motion causes less damage than drying hair naturally.

  3. Polymer composite principles applied to hair styling gels.

    2008-01-01

    A novel approach is taken to understand the mechanical performance of fixative-treated hair tresses. Polymer composite principles are applied to explain the performance. Examples are given for polyacrylate-2 crosspolymer that show that the choice of neutralizer affects the film properties of anionic acrylic polymers by plasticization or by hardening through ionic (physical) crosslinking. The effect of these changes in the polymer film on the composite properties was determined by mechanical stiffness and high-humidity curl retention testing. It is shown that both adhesion to the hair and polymer cohesion are important in determining fixative polymer performance. The implications of the results for the formulation of fixative systems are discussed.

These two novels are L’altra amante by Elisabetta Rasy (1990, explicit rewriting of La fausse maîtresse, and L’inizio è in autunno by Francesca Sanvitale (2008, built on Adieu.Although these two kinds of rewriting are very different, they both explore the potentialities of Balzac’s narration through less famous texts of the Comédie humaine

  8. Revegetation of Copper Mine Tailings with Ryegrass and Willow

    HAO Xiu-Zhen; ZHOU Dong-Mei; SI You-Bin

    2004-01-01

    To restore vegetation on metal mine tailings is very difficult because they often contain high concentrations of heavy metals, low nutrient content and low water retention capacity. This study involved 3 experiments that evaluated the effects of 4 treatment amendments: montmorillonite, rice straw, organic manure and chemical fertilizer on the growth of ryegrass (Lolium perenne L.) and willow (Saliz viminalis L.) with Cu and Zn mine tailings from two mining areas. The results showed that ryegrass was the most tolerant of 4 crops to Cu toxicity. Also when organic manure, which contained high concentrations of inorganic salts, was added to the mine tailings, it significantly hindered ryegrass growth (P = 0.05).Meanwhile, with ryegrass organic manure significantly increased (P= 0.05) the extractable Cu concentration in both mine tailings. When montmorillonite was used as a mine tailings amendment with willow, the height and tress number at the 1st cut were significantly greater (P =- 0.05) than a control without montmorillonite. However there was no significant difference for height, tress number, dry weight or root dry weight at the 2nd cut. So, amendment applications to reduce metal toxicity and increase nutrients retention in mine tailings were essential during revegetation of mine tailings.

  9. Visual attention to and perception of undamaged and damaged versions of natural and colored female hair.

    2013-03-01

    Female hair color is thought to influence physical attractiveness, and although there is some evidence for this assertion, research has yet not addressed the question if and how physical damaging affects the perception of female hair color. Here we investigate whether people are sensitive (in terms of visual attention and age, health and attractiveness perception) to subtle differences in hair images of natural and colored hair before and after physical damaging. We tracked the eye-gaze of 50 men and 50 women aged 31-50 years whilst they viewed randomized pairs of images of 20 natural and 20 colored hair tresses, each pair displaying the same tress before and after controlled cuticle damage. The hair images were then rated for perceived health, attractiveness, and age. Undamaged versions of natural and colored hair were perceived as significantly younger, healthier, and more attractive than corresponding damaged versions. Visual attention to images of undamaged colored hair was significantly higher compared with their damaged counterparts, while in natural hair, the opposite pattern was found. We argue that the divergence in visual attention to undamaged colored female hair and damaged natural female hair and associated ratings is due to differences in social perception and discuss the source of apparent visual difference between undamaged and damaged hair.

  10. Study of hair surface energy and conditioning.

    2011-01-01

    A new test method has been developed to determine surface energy of hair fibers through measurements of contact angles at two hair/liquid interfaces. By measuring changes in surface energy of the same hair fiber before and after a cosmetic treatment, effects of active ingredients and the performance of tested formulations can be evaluated.The establishment of the method is based on Fowkes theory (1,2) described with two components, a dispersive and a non-dispersive component. The non-polar liquid used in this study was diiodomethane, and the polar liquid was benzyl alcohol. A Kruss 100 Tensiometer was used to measure contact angles of hair fibers. Virgin dark brown and regular bleached hairs were treated with selected conditioner formulations. Reductions in combing forces of hair tresses before and after respective treatments were correlated with decreases in average surface energy of hair fibers obtained from the corresponding tresses.Experimental results indicate that the average surface energy of hair fibers treated with conditioners decreases and the hydrophobicity of the hair surface increases, the results correlate well with the reduction in combing forces after respective treatments. This research work provides a new methodology to evaluate/screen conditioning performance of hair care ingredients and formulations for development of better products.

    2017-01-12

    The aim of this paper is to observe the evolution and evaluate the 'realness' and authenticity in Anatomy Art, an art form I define as one which incorporates accurate anatomical representations of the human body with artistic expression. I examine the art of 17th century wax anatomical models, the preservations of Frederik Ruysch, and Gunther von Hagens' Body Worlds plastinates, giving consideration to authenticity of both body and art. I give extra consideration to the works of Body Worlds since the exhibit creator believes he has created anatomical specimens with more educational value and bodily authenticity than ever before. Ultimately, I argue that von Hagens fails to offer Anatomy Art 'real human bodies,' and that the lack of bodily authenticity of his plastinates results in his creations being less pedagogic than he claims.

    Science.gov (United States)

    Golden, Janet; Abel, Emily K

    2014-10-01

    Drawing on a large cache of letters to John and Frances Gunther after the death of their son as well as memoirs and fiction by bereaved parents, this essay challenges the assumptions of secularization that infuse histories of twentieth-century American medicine. Many parents who experienced the death of children during the postwar period relied heavily on religion to help make sense of the tragedies medicine could not prevent. Parental accounts included expression of belief in divine intervention and the power of prayer, gratitude for God's role in minimizing suffering, confidence in the existence of an afterlife, and acceptance of the will of God. Historians seeking to understand how parents and families understood both the delivery of medical care and the cultural authority of medical science must integrate an understanding of religious experiences and faith into their work.

  17. Toward an Optimal Position for IVC Filters: Computational Modeling of the Impact of Renal Vein Inflow

    Energy Technology Data Exchange (ETDEWEB)

    Wang, S L; Singer, M A

    2009-07-13

    The purpose of this report is to evaluate the hemodynamic effects of renal vein inflow and filter position on unoccluded and partially occluded IVC filters using three-dimensional computational fluid dynamics. Three-dimensional models of the TrapEase and Gunther Celect IVC filters, spherical thrombi, and an IVC with renal veins were constructed. Hemodynamics of steady-state flow was examined for unoccluded and partially occluded TrapEase and Gunther Celect IVC filters in varying proximity to the renal veins. Flow past the unoccluded filters demonstrated minimal disruption. Natural regions of stagnant/recirculating flow in the IVC are observed superior to the bilateral renal vein inflows, and high flow velocities and elevated shear stresses are observed in the vicinity of renal inflow. Spherical thrombi induce stagnant and/or recirculating flow downstream of the thrombus. Placement of the TrapEase filter in the suprarenal vein position resulted in a large area of low shear stress/stagnant flow within the filter just downstream of thrombus trapped in the upstream trapping position. Filter position with respect to renal vein inflow influences the hemodynamics of filter trapping. Placement of the TrapEase filter in a suprarenal location may be thrombogenic with redundant areas of stagnant/recirculating flow and low shear stress along the caval wall due to the upstream trapping position and the naturally occurring region of stagnant flow from the renal veins. Infrarenal vein placement of IVC filters in a near juxtarenal position with the downstream cone near the renal vein inflow likely confers increased levels of mechanical lysis of trapped thrombi due to increased shear stress from renal vein inflow.

    Full Text Available This article analyzes management as a self-organized system, in which the manager sees himself as a member of the organization he manages. He builds on the contributions of Gothard Gunther, who developed a Loqical system of multiple values, Lars Lofgren, who proposed the notion of 'autology', and Francisco Varela, who expanded the calculus of indications of G. Spencer-Brown, transforming in into the calculus of self-indication. Von Foerster broadens the notion of autology and presents a general interpretation of the concept of computations based on trivial and non-trivial machines, in order to broadly develop the calculus of recursives. The article concludes with the application of those ideas to the analysis of self-organization in the socioadministrative context.Este artículo analiza la administración como un sistema autoorganizado, donde el administrador se ve a sí mismo como miembro de la organización que administra.

    Untreated and bleached hair samples were analysed by FTIR spectroscopy. Cysteic acid and cysteine-S-thiosulphate were analysed by different data manipulations and various sampling techniques. Single-fibre analysis was achieved using the IR-microscope attachment to the FTIR instrument (transmission mode). An ATR diamond crystal was also used for both single fibres and tresses; this sampling technique was compared to a contact sample ATR cell based on a ZnSe crystal. The microscope was found to be very useful for the analysis of small portions of hair fibres; the effect of weathering along the length of the fibres and the extent of variability among the single fibres was assessed by this technique. The results clearly show a trend in the cysteic acid content increasing from the mid-point to the tip; it was found that hair samples are very heterogeneous. A standard variation of up to 11% is reported for the mean value of the intensity of absorption of cysteic acid in untreated fibres belonging to the same tress sample. The value of the variation decreases when the tress is bleached -- the longer the bleaching process the lower the value of the standard variation (4.5% for hair fibres bleached for 60 min using hydrogen peroxide). The contact sample ATR cell gave poor reproducibility as only poor sample-crystal contact was achieved and the level of noise recorded was too high to allow accurate detection. However the ATR diamond crystal was found to give sensitive and reproducible spectra since much higher levels of transmittance were achieved (better sample-crystal contact); this technique allowed measurements of groups of seven to nine hair fibres at once, but did not provide reproducible spectra of single fibres. Different data manipulations have been assessed; these include derivatization and calculation of peak heights and areas (ratioed by the intensity of absorption of the peaks chosen as internal standards to the amide III 1232--1242 cm-1 and CH2 stretching 1451

    These are Lecture Notes of a course given by the author at the French-Spanish School "Tresses in Pau", held in Pau (France) in October 2009. It is basically an introduction to distinct approaches and techniques that can be used to show results in braid groups. Using these techniques we provide several proofs of well known results in braid groups, namely the correctness of Artin's presentation, that the braid group is torsion free, or that its center is generated by the full twist. We also recall some solutions of the word and conjugacy problems, and that roots of a braid are always conjugate. We also describe the centralizer of a given braid. Most proofs are classical ones, using modern terminology. I have chosen those which I find simpler or more beautiful.

    Full Text Available This article presents an experimental study of the characterization of clay blocks stabilized with cement and/or recycled papers as construction materials. When they are utilized as finish for building envelops, they must have appropriate mechanical strength and water stability. The measurements of the mechanical and thermophysical properties show differences between the properties of four investigated specimens. Mechanical properties such as compression and tensile tresses of clay-cement and clay-cement-paper mixtures are found to be quite similar but are two to three times greater respectively for clay-paper and purely clay blocks. The values of the thermophysical properties of blocks incorporating paper show improvement of their thermo insulation performances.

    This paper presents an example of the application of data mining techniques to obtain hidden knowledge from the historical data of a hot dip galvanizing process and to establish rules to improve quality in the final product and to reduce errors in the process. For this purpose, the tuning records of a hot dip galvanizing line where coils with adherence problems in the zinc coating had been identified were used as starting point. From the database of the process, the classical data mining approach was applied to obtain and analyze a number of decision trees hat classified two types of coils, i.e. those with the right adherence and those with irregular adherence. The variables and values that might have influenced the quality of the coating were extracted from these tress. Several rules that may be applied to reduce the number of faulty coils with adherence problems were also established. (Author) 24 refs.

    The problem of object recognition is computationally expensive, especially when large amounts of data is involved. Recently, techniques in deep neural networks (DNN) - including convolutional neural networks and residual neural networks - have shown great recognition accuracy compared to traditional methods (artificial neural networks, decision tress, etc.). However, experience reveals that there are still a number of factors that limit scientists from deriving the full performance benefits of large, DNNs. We summarize these challenges as follows: (1) large number of hyperparameters that have to be tuned against the DNN during training phase, leading to several data re-computations over a large design-space, (2) the share volume of data used for training, resulting in prolonged training time, (3) how to effectively utilize underlying hardware (compute, network and storage) to achieve maximum performance during this training phase. In this presentation, we discuss a cross-layer perspective into realizing effic...

    tress release model used to be applied to seismicity study of large historical earthquakes in a space of large scale. In this paper, we improve the stress release model, and discuss whether the stress release model is still applicable or not in the case of smaller spatio-temporal scale and weaker earthquakes. As an example of testing the model, we have analyzed the M(6 earthquakes in recent about 100 years. The result shows that the stress release model is still applicable. The earthquake conditional probability intensity in Taiwan area is calculated with the improved stress release model. We see that accuracy of earthquake occurrence time predicted by the improved stress release model is higher than that by Poisson model in the test of retrospect earthquake prediction.

    The romantic landscape park was established in 1824 by order of one of the best-known aristocrats at the time, Princess Dorothea Talleyrand Perigold, Dutchess of Dino. The park is an example of amenity horticulture of artistic value that has survived to this day. The creator of the park was the talented landscape architect Peter Joseph Lenné. In its current state, the park differs significantly from the image on lithographs of the past. Upon carrying out field investigations and comparative studies, it was established that the maintained stand of tress holds high compositional value. The conclusions of the article define the current threats to the longevity of the park as well as highlighting the plan of revalorization works.

    @@ Introduction The association between pulmonary interstitial fibrosis and the development of bronchogenic carcinoma in a patient with scleroderma has been reported rarely[1]. It is hypothesized that intense epithelial proliferation that is accompanied by the .brotic process increases the occurrence of carcinomatous changes[2]. We report the case of a pa-tient who presented with 3-year history of Raynaud's phenomenon, gradual tightening of the skin which was ignored by the patient and her family members, and a 2-week history of severe respiratory dis-tress with left shoulder and upper back pain followed by the develop-ment of paraparesis. After a series of examinations, the patient was diagnosed with scleroderma and simultaneously with bronchogenic carcinoma and multiple distant metastases.

    Different kinds of silicones were incorporated directly into permanent and semi-permanent hair dyes. To ensure that the silicone was deposited to the hair fibers Si deposition was measured. Hair treated with a silicone free control or the silicone modified hair dyes was tested for color and lightness change (fading) by washing the treated tresses several times and measuring the color change. In a second experiment, hair treated with permanent hair dye was treated with UV radiation to show if silicones can reduce the color change initiated by UV light. The influence of the silicones to dry combing forces of permanent dyed hair untreated and treated with UV was also investigated. The tests showed that dimethiconol/dimethicone mixtures can reduce the washout of hair colorant clearly and silicone resins like trimethylsiloxysilcate or propylphenylsilsesquioxane are able to decrease the color change occurred by UV radiation in dyed hair.

    The abundant data of focal mechanism solutions in Tangshan region, China, are inverted for the tectonic stress field. Combined with tectonophysical consideration, the magnitude of the three principal stresses, as well as their vertical variation under the average crustal rock property, in the source region of the 1976 Tangshan earthquake is estimated. The relationship between crustal stress and friction (c, pore pressure P0 and stress shape factor ( is studied. The paper draws the conclusion that the vertical increasing rate of the maximum principal stress ( is directly proportional to friction, and inversely to pore pressure P0 and stress shape factor ( ; while the vertical increasing rate of the minimum principal tress ( is directly proportional to pore pressure P0, inversely to friction (c and stress shape factor (. This study is a try to invert the data of focal mechanism solutions for the complete stress tensor.

Un échantillon non probabiliste de 262 jeunes (173 filles, 89 garçons), âgés de 14 à 22 ans (M = 17,9 ans) a été constitué. Des comparaisons bivariées et un modèle d’équations structurales ont été réalisés. Les jeunes LGBTQ affichent un sentiment de sécurité à l’école et une réussite scolaire autoévaluée plus faibles et un niveau de détresse psychologique plus élevé. Les résultats montrent que la victimisation homophobe, le soutien social des amis, la détresse psychologique et le sentiment de sécurité à l’école jouent un rôle médiateur important dans la réussite scolaire autoévaluée des jeunes LGBTQ. Ces constats appuient l’importance de mettre en place des interventions pour réduire l’homophobie dans les écoles et soulignent le rôle central des pairs dans cet effort. PMID:28191287

Sua hipótese principal é a de que os autores analisados convergem para uma crítica comum às teses fundamentais das teorias sociológicas clássicas que afirmam que o direito é um epifenômeno das relações sociais dos diversos agentes e seus interesses: indivíduos, classes, corporações, partido etc. A Teoria Sistêmica, ao contrário, afirma que o direito pode ser analisado como um subsistema social que, a partir da operação de um código próprio, imprime um sentido e um conteúdo às comunicações dos agentes da ação, de tal maneira que não apenas as relações sociais entre os agentes criam o direito, mas também o direito cria realidades orientadoras das ações dos agentes.This article proposes a critical analysis of the contributions of Niklas Luhmann and Gunther Teubner to the development of the Systems Theory of Law (STL. Its main hypothesis is that the authors in question converge towards a shared critique of the basic theses of classical sociological theories, which assert that law is an epiphenomenon of the social relations of a variety of agents and their distinct interests: individuals, classes, corporations, parties, and so on. In contrast, Systems Theory claims that law can be analyzed as a social subsystem which, based on the operation of its own code, imprints a meaning and content to the communications of the action's agents. This not only means that law is created by social relations between agents, but that law also creates realities that guide the actions of agents.

    Animal and human anatomy is among the most complex systems known, and suitable teaching methods have been of great importance in the progress of knowledge. Examining the human body is part of the process by which medical students come to understand living forms. However, the need to preserve cadavers has led to the development of various techniques to manufacture models for teaching purposes. A variety of materials, such as wax, wood, papier-mâché, or glass, have long been used to construct animal and plant models. In the case of the human body, the most innovative, yet controversial, method of preservation has been plastination, invented by the German physician Gunther von Hagens, by which actual human bodies are preserved as odourless and aesthetic models for teaching and exhibitions. We point out in our study that the ‘hands-on’ approach that some anatomical models allow, namely, the (clastic) disassembly and reassembly of the parts of complex systems and their models, is not only a crucial tool for learning, but is far superior to the simple passive observation that rigid, single-piece models allow. And what is valid for the learning of anatomy can be generalized to the acquisition of knowledge of other complex physical systems.

    This study is a long-term follow-up to the Concord Prison Experiment, one of the best-known studies in the psychedelic psychotherapy literature. The Concord Prison Experiment was conducted from 1961 to 1963 by a team of researchers at Harvard University under the direction of Timothy Leary. The original study involved the administration of psilocybin-assisted group psychotherapy to 32 prisoners in an effort to reduce recidivism rates. This follow-up study involved a search through the state and federal criminal justice system records of 21 of the original 32 subjects, as well as personal interviews with two of the subjects and three of the researchers: Timothy Leary, Ralph Metzner and Gunther Weil. The results of the follow-up study indicate that published claims of a treatment effect were erroneous. This follow-up study supports the emphasis in the original reports on the necessity of embedding psilocybin-assisted psychotherapy with inmates within a comprehensive treatment plan that includes post-release, nondrug group support programs. Despite substantial efforts by the experimental team to provide post-release support, these services were not made sufficiently available to the subjects in this study. Whether a new program of psilocybin-assisted group psychotherapy and post-release programs would significantly reduce recidivism rates is an empirical question that deserves to be addressed within the context of a new experiment.

It was found that at the early stage of film formation particles could coagulate into the form of diffusion-limited aggregation (DLA) on a free substrate surface. By using scanning tunnelling microscopy, Hwang, Schroder, Gunther and Behm [Phys. Rev. Lett. 67 (1991) 3279] recently showed that on the clean Ru surface, Au atoms grew into irregular islands of a fractal character as well. Similar monolayer growth was also found on a constrained surface, i.e., the interface between two lattice planes. In this paper, we report on the cluster aggregation behavior between two metallic layers. Samples were prepared by alternatively depositing pure constituent materials onto freshly cleaved NaCl single crystals in a high vacuum. Transmission electron microscopy was used to characterize the surface construction. It was found that KBr dendritic islands on the constrained surface also had a fractal geometry. The growth dynamics could be modified by adding interface impurities. Our experiment showed that Al addition onto the constrained surface could accelerate the growth process and degraded the fractal dimension. Detailed results will be presented, and some possible mechanisms will also be discussed.

    The Gunther's vector-free method (GM), using PCR-amplified full length HBV-DNA (fl-HBV-DNA), is currently the best in vitro HBV replication system despite the low intracellular HBV-DNA production. The replication efficiency and HBsAg secretion of 12 isolates from HBsAg/HBeAg positive sera by GM, Monomer-Linear-Sticky-Ends-DNA (MLSE) and Monomer-Circular-Closed (MCC) were compared in HuH7 cells. Eight of twelve genomes (67%) were replication competent by GM; however direct sequencing (DS) showed that more than 80% of input DNA was undigested in spite of SapI treatment. Replication Intermediates (RI) were detected earlier (24 vs. 48h) and in higher amounts (2.51±0.32 and 6.43±0.43 fold) by MCC than GM or MLSE. By MCC 10 of 12 genomes (83%) were replication competent and 7 produced high RI levels. RI and HBsAg kinetics correlated positively in MCC (R=0.696, p=0.017 overall; R=0.928, p=0.008), but not in GM (R=-0.437, p=0.179 overall; R=-0.395, p=0.439) in genotype D isolates. In conclusion, HBV-DNA circularization prior transfection improves in vitro viral replication and replication competent HBsAg production, mimicking better the in vivo conditions.

    Full Text Available What is the territorial pattern of Brazilian political parties? What kind of relation this spatiality present with the party system? In order to answer these questions, this articles focus on three main objectives. Firstly, it will investigate the systematic pattern of political organization and affiliation in Brazilian municipalities. Secondly, it will perform an exploratory analysis of the spatial distribution of the political parties’ organization in Brazil. Third, it will produce some tentative hypotheses concerning the causal relations between party organization, party system structure, and electoral performance. Teoretically, this work will be based on the work of Panebianco (2005 [1988], as well as it will employ extensively some more recent analyses such as those from Katz and Mair (1995 and Gunther and Diamond (2003. The methodology used will, most of all, perform an Exploratory Spatial Data Analysis (esda. The results reveal that there were a constant movement towards expansion of party affiliation in Brazilian territory and it is manifested through a structural difference between large (with national territorial coverage and small parties (mostly regional in terms of party organization.

    The uroporphyrinogen III synthase (UROS) enzyme (also known as hydroxymethylbilane hydrolyase) catalyzes the cyclization of hydroxymethylbilane to uroporphyrinogen III during heme biosynthesis. A deficiency of this enzyme is associated with the very rare Gunther's disease or congenital erythropoietic porphyria, an autosomal recessive inborn error of metabolism. The current study investigated the possible role of UROS (Homo sapiens [EC: 4.2.1.75; 265 aa; 1371 bp mRNA; Entrez Pubmed ref NP_000366.1, NM_000375.2]) in evolution by studying the phylogenetic relationship and divergence of this gene using computational methods. The UROS protein sequences from various taxa were retrieved from GenBank database and were compared using Clustal-W (multiple sequence alignment) with defaults and a first-pass phylogenetic tree was built using neighbor-joining method as in DELTA BLAST 2.2.27+ version. A total of 163 BLAST hits were found for the uroporphyrinogen III synthase query sequence and these hits showed putative conserved domain, HemD superfamily (as on 14(th) Nov 2012). We then narrowed down the search by manually deleting the proteins which were not UROS sequences and sequences belonging to phyla other than Chordata were deleted. A repeat phylogenetic analysis of 39 taxa was performed using PhyML and TreeDyn software to confirm that UROS is a highly conserved protein with approximately 85% conserved sequences in almost all chordate taxons emphasizing its importance in heme synthesis.

    T HE CHANCE TO SEE a wild grizzly bear is often the first or second reason people give for visiting Yellow - stone National Park. Public interest in bears is closely coupled with a desire to perpetuate this wild symbol of the American West. Grizzly bears have long been described as a wilderness species requiring large tracts of undisturbed habitat. However, in today’s world, most grizzly bears live in close proximity to humans (Schwartz et al. 2003). Even in Yellowstone National Park, the impacts of humans can affect the long-term survival of bears (Gunther et al. 2002). As a consequence, the park has long supported grizzly bear research in an effort to understand these impacts. Most people are familiar with what happened when the park and the State of Montana closed open-pit garbage dumps in the late 1960s and early 1970s, when at least 229 bears died as a direct result of conflict with humans. However, many may not be as familiar with the ongoing changes in the park’s plant and animal communities that have the potential to further alter the park’s ability to support grizzly bears.

    The consequences of alcoholism on the mental health of spouses of lifetime at-risk drinkers are only known from studies on alcoholics already in treatment. A retrospective analysis was conducted using data from a Quebec community health survey. The purpose of this study was twofold. First, our goal was to ascertain the mental health of female spouses living with a male lifetime at-risk drinker. Secondly, we wanted to examine the relationship between male lifetime at-risk drinkers (aged 30-54 years) and the psychological distress of their nondrinking female spouses. Lifetime at-risk drinking, for the purposes of this study, was defined as having at least two positive answers to the CAGE questionnaire. Couples wherein both spouses were deemed not at-risk for problem drinking by the CAGE instrument (0 or 1 positive answer) formed the control group. Psychological distress was measured using the Indice de Détresse Psychologique de l'Enquête Santé Québec (Préville, M., Boyer, R., Potvin, L., Perreault, C., & Légaré, G. (1992). La détresse psychologique: détermination de la fiabilité et de la validité de la mesure utilisée dans l'enquête Santé Québec. Cahier de recherches #7, Montréal, Santé Québec.). It measures symptoms of anxiety, depression, aggressivity, and cognitive impairments. Scores of >or=22 (out of 100) were indicative of a high level of psychological distress. This study confirmed higher levels of psychological distress in female spouses of male lifetime at-risk drinkers in the general population. An exploratory study examined the association between the psychological distress of female spouses and each of the following nine independent variables: male partner lifetime at-risk drinker, stressful life events, job situation, socioeconomic status, perceived health status, presence of children less than 15 years, length of the marital relationship, presence of a confidant, and availability of social support. Lifetime at-risk drinking is a risk

    In order to investigate the influence of main design parameters on anchorage performance and internal stress distribution of wedge-bond anchorage for CFRP tendons, five groups of parameter tests on wedge-bond anchorage were designed. The ultimate load, slip deformation of anchor ring and stress of metal sleeve stations were determined. The influence of design parameters on anchorage performance, the tress distribution and variation of metal sleeve were contrastively investigated through static loading testing. The results show that the anchorage performance with metal sleeve thickness of 2 mm, a wedge length of 65 mm, bond length of 500 mm is optimal. The anchor between wedge and metal sleeve is good without relative displacement. The tress distribution and variation of metal sleeve can reflect the internal stress distribution of anchorage, and the perk of stress curve indicates bonding failure between colloid and CFRP tendon near the observation point.%为研究CFRP筋复合型锚具的主要设计参数对锚固性能的影响及锚具内部受力情况,设计了5个复合型锚具的参数静载试验,测量了锚具的极限荷载、锚环-CFRP筋间滑移变形和金属筒测点应变,通过静载试验对比分析了各设计参数对锚固效果的影响,以及金属筒表面应力的分布情况与变化规律.研究结果表明:当金属筒壁厚为2 mm,夹片夹持长度为65 mm,粘结长度为500 mm时,锚具的锚固性能较好;夹片-金属筒间锚固良好,无滑移;金属筒应力分布与变化可反映锚具内部受力情况,测点应力曲线峰值预示该位置附近的胶体与CFRP筋间的粘结破坏.

    An increasing number of researchers have applied secondary-structure based multiple alignments of rDNA genes in phylogeny. These studies mostly depended on a few valuable divergent domains in LSU and SSU rDNA. Yet other divergent domains, e.g. D1, were poorly investigated and rarely used. However, these domains might contain additional evolutionary data and play a vital role in DNA-based phylogenetic study. Here, we investigated all available D1 sequences of Arachnida taxa and predicted corresponding secondary structures to help identify homologous positions in the D1 region. Long insertions were found exclusive to Eriophyoidea and folded into three newly proposed helices. Non-Acari taxa were all GC rich. In Acari, most Trombidiformes and all Mesostigmata (Parasitiformes) taxa were AT rich and Ixodida (Parasitiformes) GC rich; however there was no consistent base bias in Sarcoptiformes sequences. For Eriophyoid mites, genera Cecidophyopsis and Aceria were both well supported in MP, NJ, ME and ML tress based on D1 sequences, and clusters of Cecidophyopsis species were identical with former study. This demonstrated that the D1 region could act as a valuable molecular marker in phylogenetic reconstruction of Eriophyoidea. Additionally, D1 has been proven suitable in phylogenetic analysis at the family and genus level in Acari, but not in Opiliones.

    Full Text Available Habitat destruction and hunting are one of the major threats to endangered western hoolock gibbon (Hoolock hoolock in India. Due to large scale deforestation, important feeding and roosting tress are destroyed thereby creating shortage of food all-round the year. In non-availability of preferred food, these gibbons are bound to switch their diet and eat a diet of less nutritive value. This unwanted diet-switch may lead to severe nutritional stress leading to low population densities, reduced litter and a breach in their nutritional threshold may also cause sudden die-off. Acute food supply may cause deficiency of total energy and protein supply in primates which may ultimately lead to a variety of severe immune dysfunctions and an impaired resilience. It is being well known that degraded habitat leads to increase of parasite among primates, which leads to the decimation of the weak and the vulnerable. Weak immune system due to improper diet and nutrition may lead to parasite colonization, growth and fecundity.

    Full Text Available In this paper, a LGJ150/25 type ACSR transmission line and a CGU-3 type suspension clamp are taken as research objects. A contact model of the conductor and the clamp was established by using finite element method. The effects of sag angle of the conductor, holding force and tension force in section are analyzed. The results showed that the contact area in the middle of the clamp is of belt-like type. The extreme values of tress were observed on the edge of the contact area and near the edge of keeper. In clamp section, suspension angle had the greatest influence on contact stress, and then the clamp force. The tension force in section played a most important role in these affecting factors. In the exit section of clamp, the biggest impact factor was tension force in this section, then the suspension angle, the third was clamp force. The results provide theoretical basis on reducing corona loss, optimization the clamp. Doubtlessly, the conclusion has important theoretical significance and application value.

    This paper evaluates the stress corrosion susceptibility of the HAZ (heat affected zone) of the AISI 316L stainless steel of a dissimilar welding done between the ASTM A-508 steel and the AISI 316L steel, using a nickel alloy, under a chemical environment similar to the PWR (Pressurized Water Reactor) nuclear reactor primary circuit. The nickel 82 and 182 alloys were used in the GTAW (Gas Tungsten Arc Welding) and SMAW (Shielded Metal Arc Welding) processes respectively. The test at slow deformation - SSRT (Slow Strain Rate Test) was applied, using a deformation rate of 3x10{sup -7} s{sup -1}, at a temperature of 325 degree Celsius and pressure of 12.5 MPa. The susceptibility under tress corrosion evaluation was performed comparing the resistance limit, the total deformation and the fracture time obtained at the inert medium (nitrogen) and at the PWR medium. Also, the fracture surfaces were observed under a scanning electron microscope, verifying the fragile fracture regions

    The water relation and leaf gas exchange of saxoul (Haloxylon Ammodendron Bge, a C4 shrub) seedlings were studied under water stress in 2001. Saxoul seedlings maintained high transpiration when the soil moisture was above 11%. The seedlings were able to take up water from soil with above 6 % soil water content, which was the threshold level of soil moisture for seedlings. The relationship between transpiration and potential evaporation was linear for well-watered seedlings. The decrease of soil water availability led to different degrees of down-regulation of stomatal conductance, leaf transpiration and net CO2 assimilation rate. The stomata played a relatively small part in determining the net CO2 assimilation rate for the same seedling. The relationship between net CO2 assimilation rate and transpiration was linear diurnally, and reduction scale of leaf transpiration was much bigger than that of net CO2 assimilation rate by waters tress treatments, therefore intrinsic water-use-efficiency increased. High evaporative demand increased the leaf transpiration but inhibited net CO2 assimilation rate. Because of the effect of VPD on transpiration in this region, the transpiration of well-watered and mild water stress seedlings becomes responsive to change in stomatal conductance over a wider range.

We recorded 11 squamate species (6 lizards; 5 snakes. Based on diversity index value (H the highest squamate diversity was recorded from maize (1.91, followed by wheat (1.54, groundnut (1.51, sorghum (1.34 and millet (1.21. We recorded Calotes versicolor versicolor, Ophisops jerdonii and Eutropis dissimilis as most frequently sighted species in all croplands. The multivariate generalized model revealed that sightings of species differed significantly (F(5,40 = 2.89, P < 0.05; Wilk’s Λ = 0.30, Partial η2 = 0.94 among cropland types and their boundary vegetation. The cluster analysis of boundary vegetation produced two main clusters: (1 groundnut and wheat, and (2 sorghum, millet and maize. We concluded that herbs (Parthenium hysterophorus Chenopodium album, shrubs (Calotropis procera, Ziziphus jujube, Gymnosporia royleana, and grasses (Cynodon dactylon, Setaria pumila along the cropland boundary provided abode for lacertids (O. jerdonii and skinks (E. dissimilis, while tress (Acacia nilotica, Prosopis juliflora, Ziziphus mauritiana for agamids (Calotes versicolor. We suggest the inclusion of maintaining cropland boundary vegetation particularly grasses and shrubs in agricultural practices to ensure the conservation of squamate and their habitat.

  6. WEB DOCUMENT SEGMENTATION USING FREQUENT TERM SETS FOR SUMMARIZATION

    Full Text Available Query sensitive summarization aims at extracting the query relevant contents from web documents. Web page segmentation focuses on reducing the run time overhead of the summarization systems by grouping the related contents of a web page into segments. At query time, query relevant segments of the web page are identified and important sentences from these segments are extracted to compose the summary. DOM tree structures of the web documents are utilized to perform the segmentation of the contents. Leaf nodes of DOM tress are merged to form segments according to the statistical and linguistic similarity measure. The proposed system has been evaluated by intrinsic approach making use of user satisfaction index. The performance of the system is compared with summarization without using preprocessed segments. Performance of this system is more promising than the other measures like cosine similarity, jaccard measure which make use of sparse term-frequent vectors, since the most frequent term sets are considered to measure the relevance. Relevant segments alone need to be processed at run time for summarization which reduces the time complexity of the summarization process.

    Woody vegetation from 23 forest stands along the Upper Rio Negro of Venezuela and Colombia was sampled in 1982 to examine the hypothesis that the Amazon forest has been largely undisturbed since the Pleistocene, to quantify vegetation development during different stages of succession following agricultural development, and to determine the time required for a successional stand to become a mature forest. The ubiquitousness of charcoal in the tierra firme forest indicated the presence of fire associated with extreme dry periods and human disturbances. Changes in species composition, vegetation structure, and woody biomass were studied on 19 abandoned farms and four mature forest stands. Living and dead biomass for the tress and their components was determined by regression equations developed from measurements of harvested trees. The rate of recovery of floristic composition, structure, and biomass following disturbance is relatively slow. Aboveground dead biomass remained high 14 years after the forest was disturbed by the agricultural practices. The lowest dead biomass is reached 20 years after abandonment, and the largest values are found in mature forests. Data analysis of 80-year-old stands showed that the species composition approached that of a mature forest. Approximately 140 to 200 years was required for an abandoned farm to attain the basal area and biomass values comparable to those of a mature forest. The results of this study indicate that recovery is five to seven times longer in the Upper Rio Negro than it is in other tropical areas in South America.

    European aspen (Populus tremula), quaking aspen (Populus tremuloides), and their hybrids (hybrid aspen) are short-rotation, fast growing forest tree species, that apparently hold potential for biomass and energy production. Because of inherent difficulties in vegetative propagation in aspen, it has not been possible to propagate selected aspen and hybrid aspen tress on a large scale. Therefore, the aim of this project was to develop unconventional methods of vegetative propagation in aspen that can easily be adapted to nursery practices and are also cost-effective. Explants from buds, leaves, stems, and roots were cultured on a modified Woody Plant Medium for the purposes of microvegetative propagation. Protoplasts were also cultured for regenerative studies. Mainly the bud explants were employed for microvegetative propagation. A 2-step micropropagation method, which is commmercially feasible, has been developed for aspen. This method involves: (1) culture of bud explants on a medium for bud conditioning and microshoot proliferation, and (2) rooting of microshoots in peat-perlite mix. By employing this 2-step micropropagation method, several thousand plants have been regenerated from about 50 mature selected aspen and hybrid aspen trees ranging from 1 to 40 years of age. Following transfer to field conditions, tissue culture derived plants exhibited vigorous growth and attained a height of 1.5-2 meters in the first growing season. (orig.)

    Military use of unmanned aerial vehicles (UAVs) is gaining importance. Video cameras in these devices are often operated with joysticks and their image is displayed on a CRT. In this experiment, the simulated camera of a simulated UAV was slaved to the operator's head movements and displayed using a helmet mounted display (HMD). The task involved maneuvering a UAV along a winding course marked by tress. The influence of several parameters of the set-up on a set of flight handling characteristics was assessed. To enable variation of FOV and to study the effect of the HMD optics, a simulated HMD consisting of a head slaved window, was projected on a screen. One of the FOVs, generated in this way, corresponded with the FOV of the real HMD, enabling a comparison. The results show that the simulated HMD yields a significantly better performance that the real HMD. Performance with a FOV of 17 degrees is significantly lower than with 34 or 57 degrees. An image lag of 50 ms, typical of pan-and-tilt servo motor systems, has a small but significant influence on steering accuracy. Monocular and stereoscopic presentation did not result in significant performance differences.

    Full Text Available The study aimed to formulate a pure herbal shampoo and to evaluate and compare its physicochemical properties with the marketed synthetic and herbal shampoos. The herbal shampoo was formulated by adding the extracts of Acacia concinna, Sapindus mukorossi, Phyllanthus emblica, Ziziphus spina-christi and Citrus aurantifolia in different proportions to a 10% aqueous gelatin solution. Small amount of methyl paraben was added as a preservative and pH was adjusted with citric acid. Several tests such as visual inspection, pH, wetting time, % of solid contents, foam volume and stability, surface tension, detergency, dirt dispersion etc, were performed to determine the physicochemical properties of both prepared and marketed shampoos. The formulated herbal shampoo was also evaluated for conditioning performance by administering a blind test to 20 student volunteers. The formulated herbal shampoo was clear and appealing. It showed good cleansing and detergency, low surface tension, small bubble size and good foam stability after 5 min. The prepared shampoo and commercial shampoos showed comparable results for % solid contents also. The score of the conditioning performance of the tress washed with herbal shampoo was found to be 3.0 out of 4, while the score of the marketed synthetic and herbal shampoo was 3.4 and 3.3 respectively. The results indicated the formulated shampoo is having excellent conditioning performance, at par with commercially available shampoo. However, further research and development is required to improve it's quality and safety.

    Juglans regia, Robinia pseudoacacia, Eucalyptus sp. and Populus sp. plantations, suffering from Mn and Cu toxicity, were limed in order to reduce Cu and Mn solubility in soil. The purposes of the present work were: i) to study the changes in soil chemical properties after the addition of CaCO3, ii) to investigate the influence of liming on the reduction of Mn and Cu toxicity. After the addition of CaCO3 (three applications, during three successive years), pH and CaCO3 content were significantly increased, while organic C and N were significantly reduced. Exchangeable Ca concentrations have been slightly, or significantly, increased, while those of Mg have been decreased; in addition, ratios Ca/Mg and C/N have been significantly increased after liming. Impressive reductions of DTPA extractable Cu and Mn concentrations (more than 10 times in most cases) were recorded. It was also found that trees without Mn and Cu toxicity symptoms (healthy tress) before liming did not have, in many cases, significantly greater leaf Mn, Cu and Fe concentrations, than trees after soil liming (all the trees were healthy). This probably happened because excess Mn and Cu quantities had been accumulated into their root system. Finally, leaf Mn, Cu and Zn concentrations of trees suffering from toxicity were significantly decreased after soil liming, while leaf Fe concentrations, in all the plant species studied, were increased.

  13. Computer Crime Forensics Based on Improved Decision Tree Algorithm

    Full Text Available To find out the evidence of crime-related evidence and association rules among massive data, the classic decision tree algorithms such as ID3 for classification analysis have appeared in related prototype systems. So how to make it more suitable for computer forensics in variable environments becomes a hot issue. When selecting classification attributes, ID3 relies on computation of information entropy. Then the attributes owning more value are selected as classification nodes of the decision tress. Such classification is unrealistic under many cases. During the process of ID3 algorithm there are too many logarithms, so it is complicated to handle with the dataset which has various classification attributes. Therefore, contraposing the special demand for computer crime forensics, ID3 algorithm is improved and a novel classification attribute selection method based on Maclaurin-Priority Value First method is proposed. It adopts the foot changing formula and infinitesimal substitution to simplify the logarithms in ID3. For the errors generated in this process, an apposite constant is introduced to be multiplied by the simplified formulas for compensation. The idea of Priority Value First is introduced to solve the problems of value deviation. The performance of improved method is strictly proved in theory. Finally, the experiments verify that our scheme has advantage in computation time and classification accuracy, compared to ID3 and two existing algorithms

    Protein modification and damage in human hair, resulting from environmental, cosmetic and grooming stresses, create changes to visual and tactile characteristics and correlates with consumer perception of quality. This study outlines molecular-level evaluation of modification resulting from peroxide (bleaching) and alkaline straightening (relaxing) treatments. Redox proteomic profiling of virgin, bleached and relaxed hair tresses was performed, with comprehensive qualitative characterization of modification and semi-quantitative evaluation of damage through adaptation of a new damage scoring system. Modifications were mapped to specific locations in the hair proteome and a range of potential damage marker peptides identified. Virgin hair contained a baseline level of modification, consistent with environmental oxidative insult during hair growth. Hydrogen peroxide bleaching resulted in significantly increased levels of oxidative damage observable at the molecular level. This treatment also resulted in enhanced levels of dehydroalanine and dehydration products; modifications typically associated with alkali or thermal treatment and not previously been reported as a product of hair bleaching. Relaxation treatment with sodium hydroxide increased the formation of dehydroalanine and dehydration products and moderately enhanced the levels of oxidation. Cysteine was the predominant modification site for both bleaching and alkali damage. This study validates the utility and power of redox proteomic-based approaches to characterizing hair modification. This offers potential application to a wide range of damage types, as well as evaluation of new damage mitigation and repair technologies. © 2013 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

    The aim of this study was to compare the effects of sun exposure and bleaching treatments on hair mechanical properties. Tresses of virgin dark-brown hair were initially washed with lauryl sodium sulfate solution. Sun irradiation was simulated with xenon (full radiation) or mercury-vapor (full or UVB-filtered radiation) lamps. Hair was bleached using a commercial persulfate-peroxide solution. Stress/strain data were obtained from 20 fibers of each sample using a universal test machine. Breaking elongation and breaking strength were the main parameters affected by both treatments. Reduction in the breaking strength was observed for the photo-oxidized and bleached hair (compared to untreated samples). A reduction in the breaking elongation was also observed for the photo-oxidized samples. On the other hand, an increased tendency in this parameter was observed for the bleached hair. In relation to the radiation source, similar results were achieved with much less exposure time to a xenon lamp compared to a mercury-vapor lamp. When UVB radiation was filtered, no breaking strength reduction was observed, indicating that changes in hair mechanical properties are mainly related to that range of the solar spectrum.

    Lots of trials have been performed to obtain better microscopic images of hair structure. Although scanning electron microscopy (SEM) and transmission electron microscopy (TEM) provide detailed images of hair, artificial processing may modify the original images during sample preparation. To overcome this limitation, we applied newly-developed X-ray microscopy with an 80-100 nm spatial resolution to produce a detailed view of the morphological change of hair interior. This X-ray microscopy permits us to penetrate a hair shaft without any artificial change and also provides precise images of hair interior with fine resolution. We evaluated the interior morphological change of Japanese standard hair tress No. 8 by various treatments such as ultraviolet (UV) irradiation, heating, hair dyeing, decolorizing bleaching agents and permanent waving. Internal morphological images were relatively similar in both heated and UV-irradiated hair. They revealed coarsening of cuticles and dehydration of cortex and medulla. When compared with TEM, X-ray microscopy provides more intact images in the cuticle and may be a useful tool in observing fine cracks of hair cortex. Additionally, X-ray images were intact and not influenced by any processing procedures. In observing the external and internal structure of hair, its resolution seems to be somewhat lesser than TEM and there are also several remaining weaknesses to be improved. Hopefully, forthcoming technology will solve these problems in the near future.

    A new method that can chemically discriminate the visually indistinguishable sapwood from heartwood in discolored woods is presented in this paper. Discriminating between sapwood and heartwood, which are normally recognized by color in cross sections of stems of tress, is important in dendrochronological dating, as well as in evaluating qualities of woods such as durability. In tree-ring chronology, the felling date, which affects the construction date of architectures, can be estimated only in woods that have a recognizable sapwood/heartwood boundary. However, the felling date cannot be estimated in discolored woods because it has indistinguishable sapwood. Time-of-flight secondary ion mass spectrometry (TOF-SIMS) analysis of specific chemical substances retained for approximately 1300 years after felling demonstrated the presence of sapwood in a discolored ancient architectural wood of Hinoki cypress (Chamaecyparis obtusa). Direct molecular mapping by TOF-SIMS clearly indicated that the specific substances, hinokinin, hinokiresinol, hinokione, and hinokiol, started to accumulate at the sapwood/heartwood boundary where only hinokinin was localized and retained predominantly in ray parenchyma cells. The result allowed the determination of the felling date of the discolored wood. TOF-SIMS has shown to be useful for investigating the distribution of minute amounts of chemical components in woods.

    In vitro experiments have shown that subtle fluid flow environment plays a significant role in living biological tissues,while there is no in vivo practical dynamical measurement of the interstitial fluid flow velocity. On the basis of a new finding that capillaries and collagen fibrils in the interosseous membrane form a parallel array,we set up a porous media model simulating the flow field with FLUENT software,studied the shear stress on interstitial cells' surface due to the interstitial fluid flow,and analyzed the effect of flow on protein space distribution around the cells. The numerical simulation results show that the parallel nature of capillaries could lead to directional interstitial fluid flow in the direction of capillaries. Interstitial fluid flow would induce shear stress on the membrane of interstitial cells,up to 30 Pa or so,which reaches or exceeds the threshold values of cells' biological response observed in vitro. Interstitial fluid flow would induce nonuniform spacial distribution of secretion protein of mast cells. Shear tress on cells could be affected by capillary parameters such as the distance between the adjacent capillaries,blood pressure and the permeability coefficient of capillary's wall. The interstitial pressure and the interstitial porosity could also affect the shear stress on cells. In conclusion,numerical simulation provides an effective way for in vivo dynamic interstitial velocity research,helps to set up the vivid subtle interstitial flow environment of cells,and is beneficial to understanding the physiological functions of interstitial fluid flow.

    Drylands cover more than 41% of the world's surface area and are homeland for about one-third of the world's population, 90% of them in developing countries. Land degradation in the drylands is hot environmental topic as it impacts environmental quality and jeopardizes food security in developing countries. The climate of Jordan varies from dry sub-humid Mediterranean in northwestern areas to desert conditions over a distance of 100 km, where more than 90 % of the county's area receives annual rainfall of less than 200 mm. In Jordan revegetation programs are rainfed; rainfall in Jordan is characterized by variable nature, thus, these programs faces a major challenge of the low survival rate of transplanted seedlings. The present study ought to explore the visibility of using water boxes and plastic mulch as an innovative approach to enhance seedling survival and establishment of four forest tress species ( Carob, Cupressus, Quercus, and Pinus). The experiment results showed that Cupressus, and Pinus seedlings expressed the highest survival rate of 88% and 84 % respectively, flowed by Crob (64%) and Querrcus (16%). The plastic mulch significantly enhanced the seedling survival rate b y40 % over the control while the water boxes resulted in an increase of 32 % over the control.

    In this study, x-ray fluorescent spectroscopy was employed, in a non-destructive way, to analyze the influence that water-soluble, cationic hydroxyethylcellulose (i.e., polyquaternium-10) has on the deposition of silicone oil (dimethicone) onto hair. Virgin brown hair tresses were washed with various model shampoos that contained emulsified dimethicone. The shampoos were modified only by the addition or absence of polyquaternium-10. The results indicate that the cationic polymers do influence silicone oil deposition onto hair during the shampooing process. In the absence of cationic polymer, the silicone oils deposit readily, but appear to show "build-up" phenomena upon repeated washings. When a cationic polymer is present in the continuous phase of the shampoo, the build-up phenomena is significantly diminished, and silicone oil deposition remains relatively constant in repeated washings. In addition, we have noted that the molecular weight of the cationic polymer can have a strong effect on silicone oil deposition. It appears that the higher the molecular weight of the polyquaternium-10, the greater the amount of silicone deposition onto the surface of the hair. To demonstrate that the analysis technique has potential applications in commercial shampoos, we examined a commercial "2-in-1" shampoo that contains dimethicone and polyquaternium-10 and found that the data for our simple model shampoos and the commercial shampoo correlated closely.

    Full Text Available Here, we investigated the effect of chronic mild stress (CMS on the development of atherosclerosis as well as the expression of Toll-like receptors (TLRs signaling pathway in adolescent apolipoprotein E knockout (apoE-/- mice. Mice were subjected to daily CMS for 0, 4, and 12 weeks, respectively. To identify the expression of Toll-like receptor 4 signaling pathway in adolescent apolipoprotein E knockout mice subjected to CMS, we compared gene expression in aortas of stressed and unstressed mice using TLRs signaling pathway real-time PCR microarrays consisting of 87 genes. We found that atherosclerosis lesions both in aortic tress and sinuses of CMS mice were significantly increased linearly in response to duration of CMS exposure. Among 87 genes analyzed, 15 genes were upregulated in stressed mice, especially TLR4, myeloid differentiation factor 88 (MyD88, and IL-1β, and 28 genes were downregulated compared with nonstressed mice. CMS mice demonstrated markedly increased aortic atherosclerosis that were associated with significant increases in levels of expression of TLR4, MyD88, nuclear factor κB (NF-κB, MCP-1, IL-1β, TNF-α, and sICAM-1. Taken together, our results suggest an important role for TLR4 signaling pathway in atherosclerosis in a CMS mouse model.

Personne n’est épargné : enfants et vieillards, bourreaux et victimes, femmes et hommes. Abandons et absences, faim et pauvreté, attentes inassouvies et exils désespérants, maladies et difformités, tortures de toutes sortes se multiplient. La douleur et la détresse sont omniprésentes. Si la souffrance en tant que sujet résiste à tout discours conceptuel, elle s’impose néanmoins à nous et exige que nous en parlions. Le discours portant sur la souffrance semble donc à la fois dérisoirement vain et absolument nécessaire.

    Full Text Available Associating the global trend of incorporating active compounds and plants in cosmetic formulations and the vast Brazilian biodiversity, the present work aimed to study the incorporation of Brazilian vegetable oils in hair conditioner formulations, evaluating the mechanical resistance of hair fibers. The following oils were incorporated into base formulations at 5.0 % (w/w: babassu, buriti, andiroba and pequi. The formulations were applied to samples of Caucasian hair, followed by several washing steps, then the evaluation of mechanical strength. It was found that there was no statistically significant difference in mechanical resistance between samples treated with oils and the control between the first and seventh wash cycles. This fact can be explained by the possible low penetration of oils into the cortex, a region responsible for the mechanical properties of the hair fiber, since the grease composition disfavors its diffusion. The common effects of vegetable oils on the cuticle, such as filling in cracks or cavities, lubrication, and increased protein hydrophobicity cannot be excluded. The oils tested in this work were not able to raise or protect hair tresses. However, additional studies are required in order to establish the effects of oil treatments, particularly in damaged hair.

  7. Single Nucleotide Polymorphisms (SNPs) Discovery and Linkage Disequilibrium (LD) in Forest Trees

    Institute of Scientific and Technical Information of China (English)

    2005-01-01

    With completion of the Populus genome sequencing project and the availability of many expressed sequence tags (ESTs) databases in forest trees, attention is now rapidly shifting towards the study of individual genetic variation in natural populations. The most abundant form of genetic variation in many eukaryotic species is represented by single nucleotide polymorphisms (SNPs), which can account for heritable inter-individual differences in complex phenotypes. Unlike humans, the linkage disequilibrium (LD) rapidly decays within candidate genes in forest trees. Thus, SNPs-based candidate gene association studies are considered to be a most effective approach to dissect the complex quantitative traits in forest trees. The present study demonstrates that LD mapping can be used to identify alleles associated with quantitative traits and suggests that this new approach could be particularly useful for performing breeding programs in forest trees. In this review, we will describe the fundamentals, patterns of SNPs distribution and frequency, summarize recent advances in SNPs discovery and LD and comment on the application of LD in the dissection of complex quantitative traits in forest tress. We also put forward the outlook for future SNPs-based association analysis of quantitative traits in forest trees.

    PurposeThe purpose of the study is to evaluate the influence of respiratory-induced vena caval hemodynamic changes on filter migration/penetration.Materials and MethodsAfter placement of either a Gunther Tulip or Celect IVC filter, 101 consecutive patients scheduled for filter retrieval were prospectively enrolled in this study. Pre-retrieval CT scans were used to assess filter complications and to calculate cross-sectional area in three locations: at level of filter strut fixation, 3 cm above and 3 cm below. A 3D finite element simulation was constructed on these data and direct IVC pressure was recorded during filter retrieval. Cross-sectional areas and pressures of the vena cava were measured during neutral breathing and in Valsalva maneuver and identified filter complications were recorded. A statistical analysis of these variables was then performed.ResultsDuring Valsalva maneuvers, a 60 % decrease of the IVC cross-sectional area and a fivefold increase in the IVC pressure were identified (p < 0.001). There was a statistically significant difference in the reduction of the cross-sectional area at the filter strut level (p < 0.001) in patient with filter penetration. Difficulty in filter retrieval was higher in penetrated or tilted filters (p < 0.001; p = 0.005). 3D computational models showed significant IVC deformation around the filter during Valsalva maneuver.ConclusionCaval morphology and hemodynamics are clearly affected by Valsalva maneuvers. A physiological reduction of IVC cross-sectional area is associated with higher risk of filter penetration, despite short dwell times. Physiologic data should be used to improve future filter designs to remain safely implanted over longer dwell times.

    Full Text Available This paper proposes a multimodal ethnosemiotic conceptual framework for culturally themed selective Web archiving, taking as a practical example the curation of the London French Special Collection (LFSC in the UK Web Archive. Its focus on a particular ‘community’ is presented as advantageous in overcoming the sheer scale of data available on the Web; yet, it is argued that these ethnographic boundaries may be flawed if they do not map onto the collective self-perception of the London French. The approach establishes several theoretical meeting points between Pierre Bourdieu’s ethnography and Gunther Kress’s multimodal social semiotics, notably, the foregrounding of practice and the meaning-making potentialities of the everyday; the implications of language and categorisation; the interplay between (curating/researcher subject and (curated/research object; evolving notions of agency, authorship and audience; together with social engagement, and the archive as dynamic process and product. The curation rationale proposed stems from Bourdieu’s three-stage field analysis model, which places a strong emphasis on habitus, considered to be most accurately (represented through blogs, yet necessitates its contextualisation within the broader (diasporic field(s, through institutional websites, for example, whilst advocating a reflexive awareness of the researcher/curator’s (subjective role. This, alongside the Kressian acknowledgement of the inherent multimodality of on-line resources, lends itself convincingly to selection and valuation strategies, whilst the discussion of language, genre, authorship and audience is relevant to the potential cataloguing of Web objects. By conceptualising the culturally themed selective Web-archiving process within the ethnosemiotic framework constructed, concrete recommendations emerge regarding curation, classification and crowd-sourcing.

  12. Online Standard Additions Technique for La-ICP-MS Using a Desolvating Nebulizer System

    Historically, quantification with laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) has been limited to the ability to matrix match both standards and samples. This can prove problematic when a particular matrix matched standard is not readily available. Liquid standard addition has been shown1-4 as an alternative technique for quantification that does not require matrix matching; however, further fundamental study is needed especially considering the different mass flow rates delivered to the plasma from traditional pneumatic nebulizers and laser ablation itself. In this work, the authors combine a specialized low-flow desolvating nebulizer system with LA-ICP-MS. This nebulizer system efficiently removes water vapour, thereby significantly reducing oxide based mass spectral interferences. For the instrument setup, the output from the laser is combined with the dried aerosol from the nebulizer system prior to entering the ICP-MS source. By using two sources of dry aerosol, mixing efficiency is improved whilst minimising plasma power lost to solvent (water vapour) processing. The method was applied to both USGS Green River Shale and an Arkansas Womble Shale. The results showed a number of elements that were correctly quantified using the technique as compared to reference values. References Gunther, D., Cousin, H., Magyar, B., Leopold, I., J. Anal. Atom.

    Visual Grammar proposed by linguists Gunther Kress and Theo van Leeuwen provides theoretical tool for discourse analysis in the new Reading Image Era, and also provides a new perspective for reading and analyzing movie in which visual elements play a great part. American Beauty is a representative movie in terms of subject, expression and also achievement. The visual analysis of the images concerning the theme “beauty”reveals the process of the construction of the sign “Beauty” and the multi levels of the theme, and also the individual perception of beauty by characters through the choice of different sign, which reflect their distinctive value.%语言学家克雷斯和范吕文提出的视觉语法为新读图时代的语篇解读提供了理论工具,也为分析和解读以视觉元素为主要表达方式的电影提供一个新的视角。电影《美国丽人》在题材,表达和成就上都有着一定的代表性。通过围绕电影主题“美”的图片进行视觉语法分析,在电影叙事过程中,“美”的符号构建,主题的多层次性得到凸显,电影人物对于各自“美”的符号的选择表达出对于美的不同侧面的感知,从而体现各自的价值观。

    Full Text Available O objetivo deste artigo é reconstituir criticamente o debate contemporâneo de duas das perspectivas mais proeminentes da Sociologia do Direito: o "historicismo racionalista", derivado dos estudos de Max Weber, e a teoria sistêmica de Niklas Luhmann e sua variação reflexiva em Gunther Teubner. Essas duas escolas sociológicas expressam perspectivas diferenciadas para a compreensão dos nexos entre o fenômeno jurídico e as relações sociais; a despeito de suas origens germânicas, influenciaram inúmeros pensadores na Inglaterra e nos EUA. De um lado, a perspectiva weberiana, inspiradora de uma infinidade de correntes empiristas, com enorme ascendência intelectual sobre a Sociologia anglo-americana, comprometida com a sistematização de informações recolhidas em fontes primárias, históricas e documentais; de outro lado, a combinação entre a teoria sistêmica de Luhmann e o conceito de "autopoiesis" tomado à Biologia, enseja uma vigorosa interpretação sociológica do Direito que, de maneira muito engenhosa, reconstrói os objetos do Direito e da Sociologia para explicar a natureza dos fenômenos sócio-jurídicos. No ensejo de discutirmos os modelos teóricos dessas perspectivas e testarmos-lhes os limites e as potencialidades para explicação dos problemas contemporâneos relativos ao Direito e à sociedade, explicitaremos as conexões entre as afirmações gerais dessas teorias e os pressupostos gerais de suas respectivas epistemologias.

    Magnesium sulfate (MgSO4) is widely used in medicine but molecular mechanisms of its protection through influence on erythrocytes are not fully understood and are considerably controversial. Using scanning flow cytometry, in this work for the first time we observed experimentally (both in situ and in vitro) a significant increase of HCO3(-)/Cl(-) transmembrane exchange rate of human erythrocytes in the presence of MgSO4 in blood. For a quantitative analysis of the obtained experimental data, we introduced and verified a molecular kinetic model, which describes activation of major anion exchanger Band 3 (or AE1) by its complexation with free intracellular Mg(2+) (taking into account Mg(2+) membrane transport and intracellular buffering). Fitting the model to our in vitro experimental data, we observed a good correspondence between theoretical and experimental kinetic curves that allowed us to evaluate the model parameters and to estimate for the first time the association constant of Mg(2+) with Band 3 as KB~0.07mM, which is in agreement with known values of the apparent Mg(2+) dissociation constant (from 0.01 to 0.1mM) that reflects experiments on enrichment of Mg(2+) at the inner erythrocyte membrane (Gunther, 2007). Results of this work partly clarify the molecular mechanisms of MgSO4 action in human erythrocytes. The method developed allows one to estimate quantitatively a perspective of MgSO4 treatment for a patient. It should be particularly helpful in prenatal medicine for early detection of pathologies associated with the risk of fetal hypoxia.

    We report Ni isotopic data, for 58,60-62Ni, on (1) FeNi metal and sulfides in different groups of iron meteorites, (2) sulfides and a whole rock sample of the St. Séverin chondrite, and (3) chondrules from the Chainpur chondrite. We have developed improved, Multiple-Collector, Positive ion Thermal Ionization Mass Spectrometric (MC-PTIMS) techniques, with Ni + ionization efficiency at 1‰, and chemical separation techniques for Ni which reduce mass interferences to the 1 ppm level, so that no mass interference corrections need be applied, except for 64Ni (from 64Zn, at the 0.1‰ level), for which we do not report results. We normalize the data to 62Ni/ 58Ni to correct for mass dependent isotope fractionation. No evidence was found for resolved radiogenic or general Ni isotope anomalies at the resolution levels of 0.2 and 0.5 ɛu (ɛu = 0.01%) for 60Ni/ 58Ni and 61Ni/ 58Ni, respectively. From the 56Fe/ 58Ni ratios and ɛ( 60Ni/ 58Ni) values, we calculate upper limits for the initial value of ( 60Fe/ 56Fe) 0 of (a) Toluca and Odessa by Quitté et al. [Quitté G., Meier M., Latkoczy C., Halliday A. N., and Gunther D., (2006). Nickel isotopes in iron meteorites-nucleosynthetic anomalies in sulfides with no effects in metals and no trace of 60Fe. Earth Planet. Sci. Lett. 242, 16-25]. Hence, we find no need for specialized physical-chemical planetary processes for the preservation of different Ni isotope compositions, between FeNi metal and sulfides in the same iron meteorites, as proposed by the above reports nor for complex astrophysical scenarios to provide the very peculiar Ni isotope anomalies reported by these workers for sulfides.

    Full Text Available Cet article porte sur l’expérience artistique en classe de langue sous l’angle des réactions verbales. Nous proposons d’analyser les interactions orales recueillies lors d’une activité de commentaire de photographies mise en œuvre en classe de français enseigné comme langue étrangère auprès d’apprenants adultes en contexte pluriculturel. Notre perspective est focalisée sur l’une des formes de réception des œuvres, l’immersion fictionnelle. Grâce à une analogie perçue entre l’univers fictionnel et le monde réel, les apprenants construisent de l’empathie envers l’un des personnages de la photographie, ce qui les amène à participer pleinement à la fiction. Ce phénomène se manifeste par l’attribution de paroles aux personnages de l’image. C’est à travers la notion de polyphonie énonciative que nous étudions différents extraits recueillis devant la photographie Les mariés d’Arthur Tress. Lorsque les apprenants font précéder les énoncés des personnages d’un verbe introducteur, ils se comportent comme des metteurs en scène donnant des instructions à leurs comédiens. Lorsque leurs énoncés sont dépourvus de verbes de dire, ils incarnent véritablement les personnages à la manière d’acteurs. Fictional Immersion: Combining Art and Emotion in the Language Classroom Abstract: The article deals with the verbal reactions induced by an artistic experience in a language classroom. Our perspective is to analyze the oral interactions triggered by an activity asking adult learners to comment on photographs in lessons of French taught as a foreign language in a pluricultural context. This paper focuses on fictional immersion, which is one of the possible reactions to the pictures. As they perceive a form of analogy between the fictional universe and the real world, the students build empathy with one of the characters in the photograph, which encourages them to fully participate in the fiction

  1. Supplement Analysis for the Watershed Management Program EIS --Idaho Model Watershed Habitat Projects - Pahsimeroi Fence Crossing

    2004-08-11

    The Bonneville Power Administration is proposing to fund the installation of a fenced stream crossing over the Pahsimeroi River to enhance a livestock riparian enclosure. This structure would include up to four wood fence posts and two deadman anchors buried in the ground. The goal of this project is to enhance salmon and steelhead rearing and migration habitat by preventing livestock from entering the riparian area via the river. The NEPA compliance checklist for this project was completed by Carl Rudeen with the Custer Soil and Water Conservation District (August 4, 2004) and meets the standards and guidelines for the Watershed Management Program Environmental Impact Statement (EIS) and Record of Decision (ROD). The Endangered Species Act (ESA) listed species that may occur in the general vicinity of the project area are gray wolf, Canada lynx, bald eagle, Ute ladies'Tresses, Snake River chinook salmon, Snake River steelhead trout, and Columbia River Basin bull trout. It was determined that the proposed fence crossing construction project would have no effect on these species. Bald eagle, gray wolf and Canada lynx are not known to occur in the immediate project vicinity. Since the site is used primarily as livestock pasture it does not lend itself to the presence of Ute ladies'Tresses. ESA listed fish may be present in the project vicinity but will not be affected because the project does not involve instream work. Soil disturbance will be limited to the livestock pasture and to two holes that will be used to bury anchors for the suspended portion of the fence. Required river crossings will be made on foot. Requirements associated with Section 106 of the National Historic Preservation Act were handled by the Natural Resource Conservation Service (NRCS), in cooperation with staff from the U.S. Forest Service (Boise National Forest), under their existing Programmatic Agreement with the Idaho State Historic Preservation Office (SHPO).

    Curcuminoids are the major natural phenolic compounds found in the rhizome of many Curcuma species. Curcuminoids consist of a mixture of curcumin, demethoxycurcumin (DMC), and bisdemethoxycurcumin (BDMC). Although numerous studies have shown that curcumin induced cell apoptosis in many human cancer cells, however, mechanisms of BDMC-inhibited cell growth and -induced apoptosis in human lung cancer cells still remain unclear. Herein, we investigated the effect of BDMC on the cell death via the cell cycle arrest and induction of apoptosis in NCI H460 human lung cancer cells. Flow cytometry assay was used to measure viable cells, cell cycle distribution, the productions of reactive oxygen species (ROS) and Ca(2+) , mitochondrial membrane potential (ΔΨm ) and caspase-3, -8 and -9 activity. DNA damage and condension were assayed by Comet assay and DAPI staining, respectively. Western blotting was used to measure the changes of cell cycle and apoptosis associated protein expressions. Results indicated that BDMC significantly induced cell death through induced S phase arrest and induced apoptosis. Moreover, DMC induced DNA damage and condension, increased ROS and Ca(2+) productions and decreased the levels of ΔΨm and promoted activities caspase-3, -8, and -9. Western blotting results showed that BDMC inhibited Cdc25A, cyclin A and E for causing S phase arrest, furthermore, promoted the expression of AIF, Endo G and PARP and the levels of Fas ligand (Fas L) and Fas were also up-regulated. Results also indicated that BDMC increased ER stress associated protein expression such as GRP78, GADD153, IRE1α, IRE1β, ATF-6α, ATF-6β, and caspase-4. Taken together, we suggest that BDMC induced cell apoptosis through multiple signal pathways such as extrinsic, intrinsic and ES tress pathway. © 2015 Wiley Periodicals, Inc.

Approach: A qualitative research was applied to find the data in 7 forest areas of the province of Yasothon, Roi ET, Sisaket, Ubonratchathani, Burirum, Mahasarakham and Kakasin. The sample of 147 people was selected by means of a purposive sampling consisted of 42 key-informants, 70 people involved the conservation and revitalization of gurjun-oil trees and 35 general informants. The data were collected by survey, a participative observation, a non-participative observation, a structured in-depth interview, a non-structured in depth interview, a focus-group interview, a workshop and an evaluation of planting activity. Research data were analyzed according to research purposes and presented by means of a descriptive analysis. Results: The results revealed that gurjun-oil trees in Iran cultural forests (cultural forests in the north-east of Thailand were native trees which gave people a lot of useful thing; for example people used oil of gurjun-oil trees for tinder, torches and putty. The present situation is a sharp reduction in the number of trees, the forests deteriorated into denuded forests, the people degenerated into selfish persons and competed in using natural resources for living and commercial purposes. The Buddhist way concerning the conservation and revitalization of gurjun-oil trees was the participation of three sectors; they were community leaders, state leaders and monk leaders. Necessarily, all community members must do their right duties in order to conserve and revitalize gurjun-oil trees. Conclusion/Recommendations: In conclusion, the conservation and revitalization of Gurjun-oil trees must support by the participation of all social sectors then it will

    Integrin beta 4 (ITGB4) is a structural adhesion molecule which engages in maintaining the integrity of airway epithelial cells. Its specific cytomembrane structural feature strongly indicates that ITGB4 may engage in many signaling pathways and physiologic processes. However, in addition to adhesion, the specific biologic significance of ITGB4 in airway epithelial cells is almost unknown. In this article, we investigated the expression and functional properties of ITGB4 in airway epithelial cells in vivo and in vitro. Human bronchial epithelial cell line (16HBE14O-cells) and primary rat tracheal epithelial cells (RTE cells) were used to determine ITGB4 expression under ozone tress or mechanical damage, respectively. An ovalbumin (OVA)-challenged asthma model was used to investigate ITGB4 expression after antigen exposure in vivo. In addition, an ITGB4 overexpression vector and ITGB4 silence virus vector were constructed and transfected into RTE cells. Then, wound repair ability and anti-oxidation capacity was evaluated. Our results demonstrated that, on the edge of mechanically wounded cell areas, ITGB4 expression was increased after mechanical injury. After ozone stress, upregulation expression of ITGB4 was also detected. In the OVA-challenged asthma model, ITGB4 expression was decreased on airway epithelial cells accompanying with structural disruption and damage of anti-oxidation capacity. Besides, our study revealed that upregulation of ITGB4 promotes wound repair ability and anti-oxidative ability, while such abilities were blocked when ITGB4 was silenced. Taken together, these results showed that ITGB4 was a new interesting molecule involved in the regulation of wound repair and anti-oxidation processes for airway epithelial cells.

    Our purpose in this paper is to build a case for utilizing interdisciplinary science to enhance the management of parks and protected areas. We suggest that interdisciplinary science is necessary for dealing with the complex issues of contemporary resource management, and that using the best available integrated scientific information be embraced and supported at all levels of agencies that manage parks and protected areas. It will take the commitment of park managers, scientists, and agency leaders to achieve the goal of implementing the results of interdisciplinary science into park management. Although such calls go back at least several decades, today interdisciplinary science is sporadically being promoted as necessary for supporting effective protected area management(e.g., Machlis et al. 1981; Kelleher and Kenchington 1991). Despite this history, rarely has "interdisciplinary science" been defined, its importance explained, or guidance provided on how to translate and then implement the associated research results into management actions (Tress et al. 2006; Margles et al. 2010). With the extremely complex issues that now confront protected areas (e.g., climate change influences, extinctions and loss of biodiversity, human and wildlife demographic changes, and unprecedented human population growth) information from more than one scientific discipline will need to be brought to bear in order to achieve sustained management solutions that resonate with stakeholders (Ostrom 2009). Although interdisciplinary science is not the solution to all problems, we argue that interdisciplinary research is an evolving and widely supported best practice. In the case of park and protected area management, interdisciplinary science is being driven by the increasing recognition of the complexity and interconnectedness of human and natural systems, and the notion that addressing many problems can be more rapidly advanced through interdisciplinary study and analysis.

From each species, three 25-year tress were sampled, and from each one, it was taken the first 2-meter long log, which was obtained from two boards of size 7,0 x 20,0 cm (thickness x width respectively diametrically opposite from where 30 specimens were saw for each treatment. At the first one, called the combined one, the woods were subjected to heat treatment by autoclaving at 130 / ± 3°C and pressure of 2 kgf / cm ² for 3 hours and, after a conditioning period, subjected to heat in an electric oven at 160 / ± 1°C for the same period. The second treatment consisted only of heat treatment in oven. It was also evaluated the pieces of wood without treatment (control. The mechanical properties were evaluated by means of tests for determining the modulus of elasticity and rupture in bending, maximum resistance to compression parallel to the grain and Janka hardness according to ASTM D 143 (1995, and the impact resistance according to ABNT NBR 7190 (1997. For Pinus taeda wood, it was observed that treatment in an oven gave the worst outcomes, both due to the reduction in the values of supported load of a greater number of mechanical properties evaluated, but also as compared to the lowest increments in resistance when it was observed an increase to the same ones with heat treatment. In Eucalyptus grandis, the combined treatment decreased the greatest number of mechanical properties of wood.

  7. Uncovering the single top: observation of electroweak top quark production

    The top quark is generally produced in quark and anti-quark pairs. However, the Standard Model also predicts the production of only one top quark which is mediated by the electroweak interaction, known as 'Single Top'. Single Top quark production is important because it provides a unique and direct way to measure the CKM matrix element Vtb, and can be used to explore physics possibilities beyond the Standard Model predictions. This dissertation presents the results of the observation of Single Top using 2.3 fb-1 of Data collected with the D0 detector at the Fermilab Tevatron collider. The analysis includes the Single Top muon+jets and electron+jets final states and employs Boosted Decision Tress as a method to separate the signal from the background. The resulting Single Top cross section measurement is: (1) σ(p$\\bar{p}$→ tb + X, tqb + X) = 3.74-0.74+0.95 pb, where the errors include both statistical and systematic uncertainties. The probability to measure a cross section at this value or higher in the absence of signal is p = 1.9 x 10-6. This corresponds to a standard deviation Gaussian equivalence of 4.6. When combining this result with two other analysis methods, the resulting cross section measurement is: (2) σ(p$\\bar{p}$ → tb + X, tqb + X) = 3.94 ± 0.88 pb, and the corresponding measurement significance is 5.0 standard deviations.

    Full Text Available Le troisième roman d’Elizabeth Spencer, The Voice at the Back Door (1956, appartient à son cycle du Mississippi. Il traite des relations raciales et de la violence sudiste, deux thèmes qui n’avaient pas bonne presse à cette époque puisque le mouvement pour les droits civiques débutait. Le roman rappelle L’intrus (1948 de Faulkner en ce qu’il met en scène la recherche du coupable du meurtre d’un homme blanc. Cet article analyse la façon dont Spencer dépeint les manières du Sud en s’interrogeant sur les relations raciales. Le roman est également lu dans le contexte de sa publication puisque Spencer fut perçue comme une traîtresse par les Sudistes. Spencer utilise des sujets impopulaires pour révéler le paradoxe au cœur de la manière de vivre sudiste et montre combien le passé se rejoue constamment dans le présent.Elizabeth Spencer’s third novel, The Voice at the Back Door (1956, is part of her Mississippi cycle. It deals with race relations and southern violence, two highly controversial issues at the time since the Civil Rights Movements were beginning. The novel, reminiscent of William Faulkner’s Intruder in the Dust (1948, stages the search for a culprit after the murder of a white man. This paper focuses on Spencer’s portrait of southern manners and interracial relationships and analyzes the novel in the context of its publication. It will show that Spencer uses unpopular topics to expose the paradox at the core of the southern way of life and show that the past is constantly reenacted in the present.

  9. Le principe de l’interdiction du recours à la force a-t-il encore valeur positive ? Is the Prohibition of the Use of Force still a positive Law Rule?

    Full Text Available Le principe de l’interdiction du recours à la force est une pièce maîtresse dans l’édifice du système de sécurité collective mis en place après la seconde guerre mondiale. Transgressé à différentes reprises, la question de sa valeur se pose aujourd’hui. En effet, d’aucuns estiment que les multiples atteintes à ce principe ont eu pour effet d’en altérer sa valeur, de le faire tomber en désuétude. Cette affirmation doit être écartée car si la violation d’une règle de droit a évidemment des conséquences sur son effectivité, cela ne saurait remettre automatiquement en cause son existence. Même s’il y est porté atteinte, le principe de l’interdiction du recours à la force demeure une règle de droit positif.Prohibition of the use of force as a principle is a fundamental element in the structure of the collective security system established after World War II. Since it has been violated on various occasions, the question of its legal effect arises today. Indeed, some argue that multiple violations of this principle have resulted in its falling into disuse. This assertion must be dismissed because, if the breach of a legal rule obviously has an impact on its effectiveness, it does not automatically question its existence. Even when infringed, the principle of the prohibition of the use of force remains a positive law rule.

    2015-06-01

    Full Text Available Dans une lettre à son épouse, Sade fait l'éloge de la bizarrerie et l’élève au rang de catégorie esthétique sous le nom de « principe de délicatesse ». Cela peut sembler paradoxal, comme l'a bien remarqué Michel Delon, que celui qui énonce le devoir de délicatesse est celui-là même dont le nom est devenu synonyme de brutalité. Le terme est en effet ambigu et possède dans l'oeuvre du marquis plusieurs sens: de l'échange de soins entre Juliette et sa maîtresse préférée La Durand, en passant par une simple manie sexuelle, jusqu'à la fantaisie « la plus bizarre et la plus singulière de toutes », celle qui dépend d'une richesse fastueuse et qui ne s'achève que sur un tas de corps baignés de sang. Il s'agit d'abord d'examiner les différents sens du terme chez Sade ; puis d'analyser les interprétations que Roland Barthes, Annie Le Brun et Michel Delon donnent de la délicatesse scélérate ; enfin de mettre en évidence sa spécificité par rapport à la prodigalité luxurieuse.

  11. Tsunami Modeling, Forecast and Warning (Invited)

    Tsunami is an infrequent natural hazard; however, once it happens, the effects are devastating and can be on global scale, as demonstrated by the 2004 Indian Ocean tsunami. Deterministic modeling of tsunami generation, propagation and coastal behavior has become popular, at least for earthquake tsunamis. Once the earthquake parameters are specified, tsunami arrival times, heights and current velocity at specific coastal points, and inland inundation area can be estimated. Such modeling has been used to make hazard maps usually by assuming largest possible earthquakes. However, smaller tsunamis than such a worst-case scenario occur more frequently. If the hazard maps are used incorrectly, it may lose reliability of coastal residents. Probabilistic tsunami hazard assessments, similar to Probabilistic Seismic Hazard Analysis, have been made for some coasts. The output is tsunami hazard curves, i.e. annual probability (or return period) for specified coastal tsunami heights. A hazard curve is obtained by integration over the aleatory uncertainties, and a large number of hazard curves are made for each branch of logic tress representing epistemic uncertainty. Probabilistic tsunami hazard analysis is used for design of critical facilities but not popularly used for disaster mitigation. Tsunami warning systems, which have been significantly developed since 2004, rely on seismic and sea-level monitoring and pre-made numerical simulation. Real-time data assimilation of offshore sea level measurements can be used to update the warning levels. Tsunami from the February 2010 Chilean earthquake was recorded on many tide gauges and ocean bottom pressure gauges in the Pacific, before it arrived on the Japanese coast about 22 hours after the earthquake. The tsunami height was up to 2 m on the Japanese coast, causing fishery damage amounting 60 million US dollars, but did not cause any human damage.

    Full Text Available Food preservation is enhancing shelf-life and food quality to eliminate food-related illness and product spoilage, especially by the use of food additives.The growing consumer demand for effective preservation of food without altering its nutritional quality and free of potential health risks andto find an attractive and alternative approach to chemical preservatives, have stimulated research in the field of biopreservation by the use of natural or controlled microbiota and/or their antimicrobial compounds including very recent innovation: Bacillus sp., the ubiquitous, Gram positive bacteria, producing inhibitory substances like cyclic peptides and bacteriocins, with a broad antimicrobial spectrum and a history of safe use in food. Bacillus spores are also being used extensively as probiotic food supplements where they are used in human as dietary supplements and in feed for livestock and aquaculture as growth promoters.A novel concept multi-target food preservation has emerged in relation to hurdle technology stating the microbial safety, stability, sensorial and nutritional qualities of foods are based on the application of combined preservative factors (called hurdles including Bacillus sp. that microorganisms present in the food are unable to overcome, thus leading to inhibition of microbial growth by disturbing their homeostasis and metabolic exhaustion and avoiding tress reaction by bacteria. Future exploration of the natural preservatives and/or their metabolites, in combination with advanced technologies could result in replacement of chemical preservatives, or could allow less severe processing (e.g. heat treatments, while still maintaining adequate microbiological safety and quality in foods.

    Through field investigation, structure testing, geological survey of filling and structural calculation, the reason of cracked wall in a masonry building is obtained. According to the cracking reason of the wall, the corresponding reinforcement measures are proposed. The plastered wall is reinforced by added structural concrete column. The inside horizontal wall is strengthened by pres-tressed bars to improve the seismic performance of the overall structure. An addition shallow submersion foundation is added on the o-riginal foundation to minimize the net reaction force of foundation. Simultaneously, the too closed wall of water is removed and rebuilt. Finally, the cracked masonry wall is strengthened with steel meshed cement mortar. After the reinforcement processing, the structure is complete until now.%结合现场调查、结构检测、地质补勘以及结构计算,分析了某砌体教学楼墙体裂缝原因.针对墙体开裂的原因,提出了相应的加固措施.首先采用加固砖护壁柱与增设预应力拉杆的方法来提高结构整体抗震性能;其次增设浅埋式基础以减小地基净反力;同时将距离外墙太近的积水井填埋移位重建;最后对开裂墙体进行双面贴钢筋网片后喷射水泥砂浆加固处理.经过上述加固处理后该结构使用至今仍然完好.

    2011-01-01

    Full Text Available Background: Tendon transfer for radial nerve paralysis has a 100 years history and any set of tendons that can be considered to be useful has been utilized for the purpose. The pronator tress is used for restoration of wrist dorsiflexion, while the flexor carpi radialis, flexor carpiulnaris, and flexor digitorum superficialis are variably used in each for fingers and thumb movements. The present study was a retrospective analysis, designed to compare three methods of tendon transfer for radial nerve palsy. Materials and Methods: 41 patients with irreversible radial nerve paralysis, who had underwent three different types of tendon transfers (using different tendons for transfer between March 2005 and September 2009, included in the study. The pronator teres was transferred for wrist extention. Flexor carpi ulnaris (group 1, n=18, flexor carpi radialis (group 2, n=10 and flexor digitorum superficialis (group 3, n=13 was used to achieve finger extention. Palmaris longus was used to achieve thumb extention and abduction. At the final examination, related ranges of motions were recorded and the patients were asked about their overall satisfaction with the operation, their ability, and time of return to their previous jobs, and in addition, disabilities of the arm, shoulder and hand (DASH Score was measured and recorded for each patient. Results: The difference between the groups with regard to DASH score, ability, and time of return to job, satisfaction with the operation, and range of motions was not statistically significant (P>0.05. All of the patients had experienced functional improvement and overall satisfaction rate was 95%. No complication directly attributable to the operation was noted, except for proximal interphalangeal joint flexion contracture in three patents. Conclusion : The tendon transfer for irreversible radial nerve palsy is very successful and probably the success is not related to type of tendon used for transfer.

    Tryptophan, an amino acid found in hair proteinaceous structure is used as a marker of hair photodegradation. Also, protein loss caused by several chemical/physical treatments can be inferred by tryptophan quantification. Kynurenine is a photo-oxidation product of tryptophan, expected to be detected when hair is exposed mainly to UVB (290-320nm) radiation range. Tryptophan from hair is usually quantified directly as a solid or after alkaline hydrolysis, spectrofluorimetrically. However, these types of measure are not sufficiently specific and present several interfering substances. Thus, this work aimed to propose a quantification method for both tryptophan and kynurenine in hair samples, after alkali hydrolysis process, by using high-performance liquid chromatography (HPLC) with fluorimetric and UV detection. The tryptophan and kynurenine quantification method was developed and validated. Black, white, bleached and dyed (blond and auburn) hair tresses were used in this study. Tryptophan and kynurenine were separated within ∼9min by HPLC. Both black and white virgin hair samples presented similar concentrations of tryptophan, while bleaching caused a reduction in the tryptophan content as well as dyeing process. Unexpectedly, UV/vis radiation did not promote significantly the conversion of tryptophan into its photo-oxidation product and consequently, kynurenine was not detected. Thus, this works presented an acceptable method for quantification of tryptophan and its photooxidation metabolite kynurenine in hair samples. Also, the results indicated that bleaching and dyeing processes promoted protein/amino acids loss but tryptophan is not extensively degraded in human hair by solar radiation.

    Seminal fluid is the secretion from many glands comprised of several organic and inorganic compounds including free amino acids, proteins, fructose, glucosidase, zinc, and other scavenging elements like Mg(2+), Ca(2+), K(+), and Na(+). Therefore, in the view of development of novel approaches and proper diagnosis to male infertility, overall understanding of the biochemical and molecular composition and its role in regulation of sperm quality is highly desirable. Perhaps this can be achieved through artificial intelligence. This study was aimed to elucidate and predict various biochemical markers present in human seminal plasma with three different neural network models. A total of 177 semen samples were collected for this research (both fertile and infertile samples) and immediately processed to prepare a semen analysis report, based on the protocol of the World Health Organization (WHO [2010]). The semen samples were then categorized into oligoasthenospermia (n=35), asthenospermia (n=35), azoospermia (n=22), normospermia (n=34), oligospermia (n=34), and control (n=17). The major biochemical parameters like total protein content, fructose, glucosidase, and zinc content were elucidated by standard protocols. All the biochemical markers were predicted by using three different artificial neural network (ANN) models with semen parameters as inputs. Of the three models, the back propagation neural network model (BPNN) yielded the best results with mean absolute error 0.025, -0.080, 0.166, and -0.057 for protein, fructose, glucosidase, and zinc, respectively. This suggests that BPNN can be used to predict biochemical parameters for the proper diagnosis of male infertility in assisted reproductive technology (ART) centres.

    Full Text Available Les quinze dernières années ont été marquées par l’avènement de nouveaux acteurs dans le champ de la santé globale et l’augmentation de l’aide au développement en faveur de la santé. Ces acteurs ont capté une partie importante des ressources privées et publiques supplémentaires disponibles et se sont imposés comme les pièces maîtresses de ce nouvel échiquier, aux dépens des institutions traditionnelles qui ont graduellement perdu leur prépondérance et ont vu leur leadership s’affaiblir. Les choix et politiques de santé ont peu à peu échappé à la seule autorité des institutions qui en avaient jusqu’alors le mandat et en assumaient la charge. Certains pans entiers de la santé sont désormais dominés par des financeurs privés, devenus de facto prescripteurs d’orientations de santé publique. Cette nouvelle donne pose des questions essentielles de gouvernance et de responsabilité. Qui décide des orientations ? Comment les décisions sont-elles prises ? Les pays destinataires de l’aide doivent encore trop souvent subir le manque de coordination des donateurs et l’absence d’alignement des agendas. Dans ce contexte, et en prenant acte de cette nouvelle réalité, quelques pistes mériteraient d’être explorées afin de garantir que les orientations en matière de santé globale reflètent au mieux la réalité des besoins et les aspirations des pays.

The emergence of multidrug-resistant strains in such populations, favored by iterative antibiotic cures, has led to the urgent need for new therapies. Among them, bacteriophage-based therapies deserve a focus. One century of empiric use in the ex-USSR countries suggests that bacteriophages may have beneficial effects against a large range of bacterial infections. Interest in bacteriophages has recently renewed in Western countries, and the in vitro data available suggest that bacteriophage-based therapy may be of significant interest for the treatment of pulmonary infections in CF patients. Although the clinical data concerning this specific population are relatively scarce, the beginning of the first large randomized study evaluating bacteriophage-based therapy in burn infections suggests that the time has come to assess the effectiveness of this new therapy in CF P. aeruginosa pneumonia. Consequently, the aim of this review is, after a brief history, to summarize the evidence concerning bacteriophage efficacy against P. aeruginosa and, more specifically, the in vitro studies, animal models, and clinical trials targeting CF.

  1. Using Global Sensitivity Analysis to Understand the Implications of Epistemic Uncertainty in Earth Systems Modelling

    We can define epistemic uncertainty as those uncertainties that are not well determined by historical observations. This lack of determination can be because the future is not like the past, because the historical data is unreliable (imperfectly recorded from proxies or missing), or because it is scarce (either because measurements are not available at the right scale or there is simply no observation or network available). This kind of uncertainty is typical for earth system modelling, but our approaches to address it are poorly developed. Because epistemic uncertainties cannot easily be characterised by probability distributions, traditional uncertainty analysis techniques based on Monte Carlo simulation and forward propagation of uncertainty are not adequate. Global Sensitivity Analysis (GSA) can provide an alternative approach where, rather than quantifying the impact of poorly defined or even unknown uncertainties on model predictions, one can investigate at what level such uncertainties would start to matter and whether this level is likely to be reached within the relevant time period analysed. The underlying objective of GSA in this case lies in mapping the uncertain input factors onto critical regions of the model output, e.g. when the output exceeds a certain thresholds. Methods to implement this mapping step have so far received less attention and significant improvement is needed. We will present an example from landslide modelling - a field where observations are scarce, sub-surface characteristics are poorly constrained, and potential future rainfall triggers can be highly uncertain due to climate change. We demonstrate an approach that combines GSA and advanced Classification and Regression Tress (CART) to understand the risk of slope failure for an application in the Caribbean. We close with a discussion of opportunities for further methodological advancement.

    Hybrid model testing technique is widely used in verification of a deepwater floating structure and its mooring system,but the design of the truncated mooring systems which can reproduce both static and dynamic response same as the full-depth mooring system is still a big challenge,especially for the mooting systems with large truncation.A Cell-Tress Spar operated in 1500 m water depth is verified in a wave basin with 4 m water depth.A large truncation factor arises even though a small model scale 1:100 is adopted.Computer program modules for analyzing the static and frequency domain dynamic response of mooting line are combined with multi-objective genetic algorithm NSGA-II to optimize the truncared mooting system.Considering the asymmetry of layout of mooring hnes,two different truncated mooring systems are respectively designed for both directions in which the restoring forces of the.mooting system are quite,different.Not only the static characteristics of the mooting systems are calibrated,but also the dynamic responses of the single truncated mooting line are evaluated through time domain numerical simulation and model tests.The model test results of 100-year storm in the GOM are reconstructed and extrapolated to a full depth.It is found that the experimental and numerical resuits of Spar wave frequency motion agree well,and the dynamic responses of the full-depth mooring lines are better reproduced,but the low frequency surge motion is overestimated due to the smaller mooring-induced damping.It is a feasible method adopting different truncated mooring systems for different directions in which the restoring force characteristics are quite different and cannot be simulated by one truncated mooring system.Hybrid verification of a deepwater platform in wave basin with shallow water depth is still feasible if the truncated mooring systems are properly designed,and numerical extrapolation is necessary.

    Concerns regarding the long-term viability of threatened and endangered plant species are increasingly warranted given the potential impacts of climate change and habitat fragmentation on unstable and isolated populations. Orchidaceae is the largest and most diverse family of flowering plants, but it is currently facing unprecedented risks of extinction. Despite substantial conservation emphasis on rare orchids, populations continue to decline. Spiranthes parksii (Navasota ladies' tresses) is a federally and state-listed endangered terrestrial orchid endemic to central Texas. Hence, we aimed to identify potential factors influencing the distribution of the species, quantify the relative importance of each factor and determine suitable habitat for future surveys and targeted conservation efforts. We analysed several geo-referenced variables describing climatic conditions and landscape features to identify potential factors influencing the likelihood of occurrence of S. parksii using boosted regression trees. Our model classified 97 % of the cells correctly with regard to species presence and absence, and indicated that probability of existence was correlated with climatic conditions and landscape features. The most influential variables were mean annual precipitation, mean elevation, mean annual minimum temperature and mean annual maximum temperature. The most likely suitable range for S. parksii was the eastern portions of Leon and Madison Counties, the southern portion of Brazos County, a portion of northern Grimes County and along the borders between Burleson and Washington Counties. Our model can assist in the development of an integrated conservation strategy through: (i) focussing future survey and research efforts on areas with a high likelihood of occurrence, (ii) aiding in selection of areas for conservation and restoration and (iii) framing future research questions including those necessary for predicting responses to climate change. Our model could also

    Purpose: The British Society of Interventional Radiology (BSIR) Inferior Vena Cava (IVC) Filter Registry was produced to provide an audit of current United Kingdom (UK) practice regarding placement and retrieval of IVC filters to address concerns regarding their safety. Methods: The IVC filter registry is a web-based registry, launched by the BSIR on behalf of its membership in October 2007. This report is based on prospectively collected data from October 2007 to March 2011. This report contains analysis of data on 1,434 IVC filter placements and 400 attempted retrievals performed at 68 UK centers. Data collected included patient demographics, insertion and retrieval data, and patient follow-up. Results: IVC filter use in the majority of patients in the UK follows accepted CIRSE guidelines. Filter placement is usually a low-risk procedure, with a low major complication rate (<0.5 %). Cook Gunther Tulip (560 filters: 39 %) and Celect (359 filters: 25 %) filters constituted the majority of IVC filters inserted, with Bard G2, Recovery filters, Cordis Trapease, and OptEase constituting most of the remainder (445 filters: 31 %). More than 96 % of IVC filters deployed as intended. Operator inexperience (<25 procedure) was significantly associated with complications (p < 0.001). Of the IVC filters initially intended for temporary placement, retrieval was attempted in 78 %. Of these retrieval was technically successful in 83 %. Successful retrieval was significantly reduced for implants left in situ for >9 weeks versus those with a shorter dwell time. New lower limb deep vein thrombosis (DVT) and/or IVC thrombosis was reported in 88 patients following filter placement, there was no significant difference of incidence between filter types. Conclusions: This registry report provides interventional radiologists and clinicians with an improved understanding of the technical aspects of IVC filter placement to help improve practice, and the potential consequences of IVC filter

    Full Text Available The present article intents to study the tendencies of the criminal legislations of some occidental countries in the last decades, attaining to the political-criminal phenomenon that has been showing a peculiar expansion of punitivism in the central and peripheral countries, by the increasing of severity of criminal repressions and flexibilization of the penal garantism. This study has its justification on the importance of the impacts that these legislative tendencies are causing on the punitive discipline in the occidental States. It has as objective, in synthesis, to investigate the legitimacy of the paradigm of the criminal toughness that has been observed in the present times – named as “Criminal Law of the Enemy” by Gunther Jakobs – and its compatibility with the postulates that build the modern Constitutional State of Law, in compass with the impositions of the minimalist Criminal Law and of the Penal Garantism. To do so, the present study relies on international and national doctrines, aiming to put in terms the major philosophical and juridical bases of the minimalist and garantistic model, defending its close relationship with the rule of law principle. In addition, analyzes the investigated phenomenon of the penal expansionism, seeking, about this last one, to establish its general characteristics in the occidental world, for which we also undertake a research of the pertinent criminal legislation of some countries took as models. By the shown, we conclude that the expansionism of the Criminal Law model observed in the last decades in the Occident is totally incompatible with the juridical limits and guarantees disposed in the occidental constitutions, which build the model of the Penal Garantism, with protection of the citizens’ freedom against the excesses of the punitive power. Indeed, the flexibilization of these limits and guarantees operated by the penal expansionism or “Criminal Law of the Enemy” create an State

    Full Text Available Abstract Background The birth of a child with a cleft lip, whether or not in association with a cleft palate, is a traumatic event for parents. This prospective, multidisciplinary and multi-centre study aims to explore the perceptions and feelings of parents in the year following the birth of their child, and to analyse parent–child relationships. Four inclusion centres have been selected, differing as to the date of the first surgical intervention, between birth and six months. The aim is to compare results, also distinguishing the subgroups of parents who were given the diagnosis in utero and those who were not. Methods/Design The main hypothesis is that the longer the time-lapse before the first surgical intervention, the more likely are the psychological perceptions of the parents to affect the harmonious development of their child. Parents and children are seen twice, when the child is 4 months (T0 and when the child is one year old (T1. At these two times, the psychological state of the child and his/her relational abilities are assessed by a specially trained professional, and self-administered questionnaires measuring factors liable to affect child–parent relationships are issued to the parents. The Alarme Détresse BéBé score for the child and the Parenting Stress Index score for the parents, measured when the child reaches one year, will be used as the main criteria to compare children with early surgery to children with late surgery, and those where the diagnosis was obtained prior to birth with those receiving it at birth. Discussion The mental and psychological dimensions relating to the abnormality and its correction will be analysed for the parents (the importance of prenatal diagnosis, relational development with the child, self-image, quality of life and also, for the first time, for the child (distress, withdrawal. In an ethical perspective, the different time lapses until surgery in the different protocols and their

Based on the deep structure mode of Weihe basin, a numerical analysis with finite element method is made to study the stress and strain response of superficial ground subjected to the deep tectonization of upper mantle uplifting, middle crust lateral stretching and upper crust tension. The germination relationship between deep structure activities and ground fissures development is revealed. Results show that the tensile tress environment is formed by upper mantle uplifting and middle crust lateral stretching, which combines with stretching stress fields induced by surrounding blocks activity and faults dipslip, constitute the main motive resource of ground fissures development.

    The methods for assessing the efficieney of 3 kinds of cosmetics, such as sunscreening, skin-whitening and hair-caring cosmetics ,were mainly reviewed in this paper. For sunscreeing cosmetics ,the assessment methods of protective action from ultraviolet radiation in the range of A and B wavebands were introduced. For skin-whitening cosmetics, the assessment methods using zoological ,cytological and enzymlogical tests were introduced. The hair-caring cosmetics were discussed concerning the simulated tests of tress and tests (in vitro). It was pointed that ,with the increasingly extending manufacture and application of cosmetics for special use ,the detection range of their efficiency should be gradually developed from finished products to raw materials, and from animal tests and human body tests to cell tests and tests in vitro for the purpose of advancing the efficiency of detection and reducing the impacts of the cosmetics for special use to consumers.%主要综述了防晒、美白及美发三类特殊用途化妆品的功效评价方法。对防晒化妆品,从UVA的防护和评价及UVB的防护和评价作了介绍;对美白化妆品,从动物学方法、细胞学方法和酶学方法作了介绍;对美发化妆品,从发束的模拟试验和试管内试验作了介绍。指出随着特殊化妆品的生产和使用日益扩大,对它们的功效检测也应逐步从成品检测向原材料检测发展,从动物试验、人体试验向细胞试验、离体试验发展,以提高检测效率,减少对人体的伤害。

    Full Text Available Cet article s’efforce de comprendre les raisons de l’absence d’une bohème littéraire de droite en Israël. Au-delà des facteurs structurels liés à l’association naturelle de la bohème avec la gauche, soit comme un choix par défaut soit comme un terme marqué, le conservatisme inhérent à la littérature droitière est incompatible avec la renonciation au passé qui caractérise souvent les lettres israéliennes. En outre, la bohème de gauche en Israël ne tarit pas de critiques vis-à-vis de son propre pays. Cette préoccupation brille par son absence dans les écrits souvent partisans émanant de la droite. Enfin, la réception de la littérature israélienne hors d’Israël favorise nettement la bohème littéraire de gauche au point qu’on voit se dessiner une répartition complémentaire entre la droite aux commandes du pays et la gauche, maîtresse presque exclusive du Parnasse israélien.This article tries to understand why a right-wing literary Bohemianism failed to emerge in Israel. Besides the structural reasons connected with the natural association of Bohemianism with the Left, either as a default choice or as a marked option, the conservatism inherent to right-wing oriented literature is incompatible with modern Israeli attempt to get rid of the tradition. Moreover, what makes left-wing Israeli Bohemianism more credible is its constant need of self-criticism, a concern that blatantly lacks in the partisan writing emanating from the Right. Lastly, the reception abroad obviously favors left-wing Israeli Bohemianism to the extent that there might be a complementary distribution of functions between right-wing politics and left-wing literature in contemporary Israel.

  16. Protection of oxidative hair color fading from shampoo washing by hydrophobically modified cationic polymers.

    The fading of oxidative color in hair as a result of daily shampoo washing activities has become a common problem and a source of frequent complaints by consumers. The fading occurs primarily through hair dye solubility in water. One aspect of the current study investigates the physical and chemical factors that influence hair color fading during the washing process. This is accomplished by testing hair dye dissolution in water from dyed hair samples with variation of surfactant type, pH, and hair type. Furthermore, a new approach to preventing color fading is developed aiming to provide an effective barrier function for hair dye from dissolving into water. The preliminary investigation of a series of polymers with various functional groups indicates that polymers with hydrophobically modified and cationic functionalities are most effective in preventing hair dye dissolution in water. It is also evident that a synergistic effect of the polymer's hydrophobic moieties and cationic charges are important on hair color protection during shampoo washing processes. A primary example of a polymer within this category is a cationic terpolymer of vinylpyrrolidone, dimethylaminopropyl methacrylamide, and methacryloylaminopropyl lauryldimonium chloride (INCI: Polyquaternium-55). The color protection benefit of this polymer is evaluated using newly developed methodologies for evaluating hair color changes, such as hair color fading tests through multiple shampoo washes with mannequin heads and hair tresses, both derived from human hair, colorimetry, and quantitative digital image analysis. In addition, new infrared spectroscopic imaging techniques are used to detect the hair dye deposition behavior inside hair fibers both with and without the color protection treatment. Both visual and instrumental measurement results indicate that Polyquaternium-55 provides a high level of color protection when formulated in a hair color protection regimen with up to 50% color protection.

    明末战乱期间,中原各地曾有大量的寨堡修筑。这些寨堡可以根据政治倾向分为绅士寨堡和土寨两种类型。前者主要是地方绅士凭借其雄厚的财力独力修筑而成,很少借助村社力量,这反映出绅民关系的疏离。后者则为“土寇”所主导,为数众多。两类寨堡之间存在一个此消彼长的过程,土寨最终取代绅士寨堡,在中原地区确立了血腥的土寨秩序。土寨秩序的形成同样可以归因于绅民关系的疏离。明末中原寨堡是地方社会权力结构和社会关系演变的结果,是我们理解明清中原社会的一个难得的视角。%There were a large number of fortresses when the war broke out in Central China during the late Ming Dynasty. These fortresses can be divided into two types, Gentry′s fortress and local fortress, according to the owners and their political tendency. The former were built mainly by the gentry who relied on their huge wealth rather than relying on rural community power. This phenomenon reflected the alienated relation between the gentry and the lower people. The latter, which were headed by bandits, were numerous. The former were often assaulted, and in the end, when most Gentry′s fortresses were replaced by local fortress, the bloody local fortress or⁃der was set up. The formation of this order was connected with the alienated relation between the gentry and the lower people. The for⁃tress resulted from the evolution of power structure and social relation. Therefore, it is a rare perspective from which we can further study the Central Plains society during Ming and Qing Dynasties.

    Gidaa informal science camps have been held in various formats and emphases for over 10 years at Fond du Lac (FDL). These camps provided a safe place for young people to be "nerds" but did not have specific focus. In the last 5 years the camp themes became more focused on environmental issues facing the reservation. From 2009 to 2014 the camps focused on issues surrounding the health of wild rice plants. Since September 2014, we are focusing on climate literacy and how climate changes are affecting tribal environment. We learned from our wild rice themed activities that students are more focused and interested in topics that affect them and their reservation and traditional activities.Each camp has a presentation by a staff from the FDL Resource Management Division. These presentations are sometimes given on Friday evenings after dinner and yet students remain alert, respectful, and actively take notes. The presentation topic is known in advance and camp teachers (local middle and high school teachers who have been with us for 5 to 10 years) plan lessons around that topic. In addition, college students, some of them past camp participants, are on hand to assist the teachers and to provide role models. Students have investigated, for example, possible effects of climate change on the timing of rising of sugar maple sap and whether sugar maple tress will continue to thrive in their area, efforts to bring back sturgeon to local rivers and how the changes in water temperature may affect that effort, possible climate connection to decline of moose and walleye pike population at 5 weekend camps during the last academic year. We have conducted 2 surveys by an outside evaluator and will have the results before the next round of camps starts in fall 2015 to help us tweak the format if necessary. Teachers and planners (PIs) are happy with the way camps are running this year; there is a good balance of camp activities that allow teachers to translate and adapt the

    The TV Series Sha Chun is a typical show of traditional Chinese family ethics life. Familism has a strong family unity and emphasis on family heir reproduction, the tress of the Ancestor command, focusing on public property, the family characteristics of the overall honors. However, in contemporary China, conflicts between the family interests and the rights of the individual, family private morali- ty and public morality , that emphasis on men and equal rights of every member,make the old ethics face the danger of disorganization. The new family ethic should adhere to the principle of unity of emotion and justice, respect for freedom and individuality of each member, the principle of great importance to the cultivation of a sense of social responsibility. This shift is the contemporary fate of traditional Chinese family ethics.%电视连续剧《傻春》是中国典型的传统主义家庭伦理生活的当代写照。家庭主义具有强烈的家庭一体感、重视家族嗣繁衍、强调属遵祖训、注重财物公有、重视家庭整体荣誉的特点。然而在当代中国,家庭利益与个人权利的矛盾、家庭私德与社会公德的矛盾、重男思想与权利平等的矛盾,使这种伦理观在当代面临解组的危险。新型家庭伦理观应坚持亲情与正义相统一原则、尊重每个成员的自由与个性、重视社会责任感的培养等原则,这种伦理转向是传统家庭主义的当代宿命。

    Unlike simply supported beams under positive moment, the ultimate load carrying capacity of continuous steel-concrete composite beams is usually limited by either the local buckling failure of steel section or the distortional lateral buckling near interior supports, which is because the sleel plate under the negative moment near interior is subjected to compression and inclined to instability. However, the simplified plastic theory taking no account of the instability of the beam will lead to a unconservative result. Four full-scale continuous composite beams were tested, among which two were two-span beams with class 2 cross-section and two were three-span beams with class 3 cross-section. One of the two-span beams was a conventional non-pres-tressed composite beam, and the other was a composite beam preslressed with external tendons in both the positive and negative moment regions. One of the three-span composite beams was non- prestressed, and the other was prestressed only in the negative moment regions with external high-strength tendons. The experimental results indicates that all beams collapsed with the characteristic of concrete crushing in sagging moment, and the web local buckling and distortional buckling of the steel beam. The capacity of beams in positive moment can be calculated by simplified plastic theory, while the capacity of beams in negative moment is affected by section classification divided hy width to thickness ratio of the plate,the simplified calculation method based on the web buckling is agreed well with the experimental results. A numerical analysis was conducted for all the beams considering interface slipping, prestressing force, and so on, which agrees well with the experimental results.Unlike simply supported beams under positive moment, the ultimate load carrying capacity of continuous steel-concrete composite beams is usually limited by either the local buckling failure of steel section or the distortional lateral buckling near

    framework model are interpreted seismic lines, 3d-models can be generated either in time or in depth domain. Some partners will build their 3d-model in time domain and convert it after finishing to depth. Other participants will transform seismic information first and will model directly in depth domain. To ensure comparability between the different parts transnational velocity models for time-depth conversion are required at an early stage of the project. The exchange of model geometries, topology, and geo-scientific content will be achieved applying an appropriate cyberinfrastructure called GST. It provides functionalities to ensure semantic and technical interoperability. Within the project GeoMol a web server for the dissemination of 3d geological models will be implemented including an administrative interface for the role-based access, real-time transformation of country-specific coordinate systems and a web visualisation features. The project GeoMol is co-funded by the Alpine Space Program as part of the European Territorial Cooperation 2007-2013. The project integrates partners from Austria, France, Germany, Italy, Slovenia and Switzerland and runs from September 2012 to June 2015. Further information on www.geomol.eu.

  10. The Moon and the U-47 in Scapa Flow

    Schaefer, B. E.

    2005-12-01

    The skies above affect historical events here on Earth more than is generally realized. Events during wars are often tied to the Moon through operational requirements for illumination (or dark), high tides (or low), and even links to events in lunar calendars. World War II has many famous battles, commando operations, and naval sorties dictated in date by the Moon. Famous examples are D-Day (needing low tides and Full Moon illumination), the amphibious landing on Tarawa (needing but not getting high tides), El Alamein (requiring Full Moon light for the mine-clearers), the Great Escape from Stalag Luft III (chosen for the stealth possible with a New Moon), Mussolini's invasion of Albania (on Good Friday), and even Rudolf Hess' flight to Scotland (timed by a six-planet conjunction and aided in navigation by the Full Moon). This paper will concentrate on one event for which the Moon provided the primary trick for a major Nazi naval victory, while an aurora saved the British from an even worse disaster. The story is set in Scapa Flow, the huge anchorage in the Orkney Islands that was used as a primary base for the British Navy in blockading the North Sea. During World War I, German submarines had twice tried to slip into Scapa Flow but were sunk both times, and the anchorage later became the last resting place of the scuttled German High Seas Fleet. At the outbreak of World War II, then Commodore Karl Doenitz suggested that his ace U-boat captain consider sneaking into Scapa Flow to loose salvos of torpedoes at all the anchored ships. Captain Gunther Prien of the U-47 took up the challenge after realizing that the British had not completely blocked a narrow inlet. His plan was to surface the submarine and go in over the sunken block ships at the highest of spring tides. Spring tides require a syzygy (New or Full Moon), during which the high tides occur near noon or midnight. To be unobserved by onshore guards, the Moon should not be in the sky illuminating the waters

  11. Greenhouse gas emissions of drained fen peatlands in Belarus are controlled by water table, land use, and annual weather conditions

    Drainage of peatlands causes strong emission of the greenhouse gases (GHG) CO2 and N2O, sometimes combined with a weak CH4 uptake. In Belarus drained peatlands occupy about 1505000 ha or more than 7.2 % of the country area. Joosten (2009) estimates CO2 emission from degraded peatlands in Belarus as 41.3 Mt yr-1 what equals to 47 % of total anthropogenic greenhouse gases (GHGs) emission of country in 2011. However, it could not be checked if these numbers are correct since there are no GHG measurements on these sites up to now. Therefore we studied the GHG emissions with the closed chamber approach in four peatlands situated in central and southern Belarus over a period from August 2010 to August 2012. The measurements comprised eight site types representing different water level conditions, and ranging from grassland and arable land over abandoned fields and peat cuts to near-natural sedge fens. Fluxes of CH4 and N2O were determined using the close-chamber approach every second week in snow free periods and every fourth week during winter time. The annual emissions were calculated based on linear interpolation. Carbon dioxide exchange was measured with transparent and opaque chambers every 3-4 weeks and the annual net ecosystem exchange (NEE) was modeled according to Drösler (2005). Most of the drained sites were sources of CO2 in both years. NEE increased with lower mean annual water table level. The highest NEE value (1263.5 g CO2-C m-1yr-1) was observed at the driest site of the study; an abandoned fen formerly used for agriculture. In contrast, a former peat extraction site with moist peat and small Pinus sylvestris tress were sinks of CO2 with uptake to 389.6 g CO2-C m-1yr-1. The highest N2O emissions were recorded at a drained agricultural fen with mean annual rates of up to 2347 mg N2O-N m-2 yr-1. Significant fluxes of CH4 (15 g CH4C m-2 h-1) were observed only at the near-natural site in the first year of investigation when precipitation and the mean water

Cet excès de détails a pour but de fixer ou d'améliorer le statut des films, qu'il s'agisse de films canoniques, de films culte ou de films classiques, tout en donnant plus de légitimité culturelle à la lecture nostalgique des œuvres. D'autre part, le positionnement de ces films que le recours à la nostalgie transforme en prétextes à l'activation de souvenirs personnels et affectifs liés au plaisir de l'expérience cinématographique. Cet article analyse l'utilisation de cette nostalgie par les magazines grand public qui servent d'intermédiaires entre les œuvres, les institutions et les fans. Enfin, il s'interroge sur la manière dont la nostalgie se tresse aux autres discours et activités des fans dans leurs contacts avec les films.

Structural and edaphic variables were reduced through a principal component analysis (PCA; then, the association between edaphic and structural components from PCA was evaluated by multiple regressions. The existence of regionalization of these variables was studied through isotropic variograms, and autocorrelated variables were spatially mapped. PCA found two significant components for structure, corresponding to the structure of large trees (G, Gdos, Ndos and sp and of small trees (N, Nsot and Gsot, which explained 43.9% and 36.2% of total variance, respectively. Four components were identified for edaphic variables, which globally explained 81.9% of total variance and basically represent drainage and soil fertility. Regression analyses were significant (p<0.05 and showed that the structure of both large and small trees is associated with greater sand contents and low soil fertility, though they explained a low proportion of total variability (R² was 4.9% and 16.5% for the structure of large trees and small tress, respectively. variables with spatial autocorrelation were the structure of small trees, Al, silt, and sand.

    To investigate the cracking resistance and avoid the vertical and local circumferential cracks at the bottom of the concrete outer tank during the construction period due to hydration heat, concrete shrinkage and temperature changes for 160 000 m3 liquefied natural gas ( LNG ) tanks, using the finite element numerical simulation technology, the influence of shuttering material, construction quality, construction season and pouring temperature on cracks was figured out with an incremental method. The results show that concrete shrinkage leads to a sustaind growth of concrete tensile stress, the thermal stress fluctuates according to the changing of construction temperature and construction quality and construction season have a strong inference on cracks. Based on this basis, the thermal tress is dismantled according to the effect of each influencing factor, and the whole thermal stress is the superposition of the thermal stress under single influence of hydration heat, concrete shrinkage, construction season and pouring temperature. Some suggestions on anti⁃cracking measures are proposed, mainly by regulating the construction season, complementally by improving the quality of construction.%为了解160000 m3大型液化天然气( LNG)储罐混凝土外罐在施工期间的抗裂性能,避免由于水泥水化放热、混凝土收缩、外界气温变化而造成的外罐墙壁竖向开裂及扶壁柱局部环向裂缝现象,运用有限元数值模拟技术,采用增量法,分别探讨了施工模板材料、施工质量、施工季节及混凝土入模温度对混凝土外罐温度应力分布的影响及其规律。结果显示:模板对温度应力的影响作用较小,混凝土收缩导致混凝土拉应力持续增长,温度应力随着施工季节温度的变化而产生相应波动,施工质量及施工季节对温度应力的影响较大;在上述结论基础上,视温度应力结果为水化热、混凝土收缩、外界

    Introduction L'incidence des complications respiratoires postopératoires (CRPO) reste très diversement appréciées selon les critères diagnostiques retenues dans les différentes études, ce qui la fait varier de 5 à plus de 50%. Les CRPO majeurs après chirurgie de l'aorte abdominale sont responsables d'une grande morbi-mortalité pouvant aller jusqu’à 36%, d'une durée d'hospitalisation et d'un coût plus importants. Ainsi dans l'optique d'améliorer notre prise en charge périopératoire de la chirurgie de l'aorte, nous avons décidé de mener une étude pour dresser le profil épidémiologique et déterminer les facteurs de risque des complications respiratoires dans notre contexte Méthodes Il s'agit d'une étude de cohorte rétrospective du mois de Janvier 2007 au mois de décembre 2011 portant sur l'ensemble des patients opérés pour pathologie aortique au bloc opératoire central de l'hôpital Ibn Sina de Rabat, Maroc. Résultats Cent vingt cinq patients ont été inclus dans notre étude, 24 patients ont été opérés pour anévrysme de l'aorte abdominale et 101 patients pour lésion occlusive aortoiliaque. Dans notre série 22 malades soit 17,6% ont présenté une complication respiratoire majeure avec, une reventilation dans 4,8% des cas, une difficulté de sevrage de la ventilation artificielle dans 3,2% des cas, une pneumopathie dans 4% des cas, un syndrome de détresse respiratoire aigue (SDRA) dans 4% des cas et une nécessité de fibroaspiration bronchique dans 1,6% des cas. En analyse univariée: l’âge, la présence d'une BPCO avec dyspnée stade 3 ou 4, la présence d'une anomalie à l'EFR préopératoire, la présence d'un stade avancé (III ou IV) de LOAI et la reprise chirurgicale étaient statistiquement associés à la survenue d'une complication respiratoire postopératoire. En analyse multivariée, seule une anomalie à l'EFR en préopératoire constituait un facteur de risque indépendant de survenue d'une complication

    Full Text Available The conjugation of human development and sustainability of natural resources is a critical issue to our present society. The role of human activity in fire ocurrence is a good example of the difficult dialogue between development and conservation. Recent changes in land use patterns have carried along an increasing rate of fire occurrence, which implies in some cases severe effects on soil erosion and vegetation degradation. For this reason, it is critical to improve current tools to prevent and assess forest fires, so that fire occurrence may be reduced. This paper explores the use of remote sensing methods to derive fuel type maps. These maps are basic sources of information for fire behaviour modelling, since they make it possible to take into account vegetation characteristics for fire propagation. The study area is located in Cabañeros National Park (Central Spain. The fuel type mapping was based in the analysis of two satellite Landsat-TM images and auxiliary information (digital elevation models and texture images. The digital classification worked out to have a global accuracy of 83 %. The larger problems found were to distinguish between the different heights of shrubs and identifying the existence of shrubs under the tress.

    [es] La conjunción entre desarrollo y sostenibilidad del medio ambiente se torna un aspecto de singular importancia en nuestra sociedad. La incidencia de la actividad humana en la aparición de incendios forestales supone un ejemplo nítido de esa afirmación, ya que los cambios recientes en los patrones de utilización del territorio van acompañados de un notable aumento de los incendios forestales, con la consiguiente degradación del suelo y la cubierta vegetal. En este contexto, resulta de suma importancia mejorar las herramientas de prevención de incendios y evaluación de sus efectos, de cara a reducir la ocurrencia o paliar los efectos de este fenómeno.

In the part of the map in the center of which is Kosovo Field (Campo Cassovo, Veletin is marked near Janjevo (Iagneuo as a ruin: "Valetino rouin." (ato, as evidence of its earlier importance. The second mention of Veletin is made in the Map of the central course of the Danube etc., by Johann Baptist Homan, prepared in Nuremberg between 1707 and 1724. Veletin appears for the third time in the New map of Dalmatia, Croatia etc., published by Mathias Seuter in Augsburg before 1758. From the time Veletin was destroyed it was never renovated as far as we know and time took its toll. The walls of the fortress and other buildings were used by local inhabitants as a source of building materials until they completely disappeared, what apparently happened in the 70’s of the XX c. Remains of the walls whose shape can be discerned under the soil show that the foundation of the fortress was adjusted to the configuration of the ground. That is to say, the hill of Veletin ends in sheer rock on northern and north-eastern sides and is completely inaccessible (pic. 5 while on other sides there are moderately steep terraced slopes (pic. 6-9 on which rampart walls were built following topographic relief (plans 10 and 11. Two plans of the fortress Veletin were published until now (pic. 10 11. The third plan, the most accurate, was not published. It shows that the for­tress had the form of an irregular polygon, and that it was defended by three perimeters of walls forming the Upper, the Middle, and the Lower town (pic. 12. In the south-eastern part of the Lower town are remnants of a rectangular and of a round building. Archeological probes on Veletin were performed by Edi Shukriu in 1987 and 1988. Archeological material shows that the oldest settlement was formed in Neolithic period, belonging to the Bubanj-Hum culture. The younger settlement is from the Iron Age and is connected to the Suva Reka group. Finds of

    Objectives: To explore the relation of general maladjustment status to cultural orientation and stress in armed police soldiers. Methods: Totally 725 armed police soldiers including 334 with one year, 231 with 2 years, and 160 with 3 years of military service were selected. They were assessed with the General Maladjustment Scale (Gm) to evaluate maladjustment, and assessed with the Individualism and Collectivism Scale (ICS) consisting of the sub-scales of Vertical individualism subscale (VI), Horizontal individualism subscale ( HI), Vertical Col-lectvism subscale (VC), and Horizontal Collectvism subscale (HC) to evaluate cultural orientation, and assessed with the Psychological Stress Self Evaluation Test (PSET) to evaluate tress. Results: The scores of Gm and PSET were lower in the soldiers with 1 year of military service than in the ones with 2 or 3 years [(8. 2 ±3. 7) vs. (10. 5 ±4. 9), (10. 6±5. 0); (48. 1 ±8. 7) vs. (52. 1 ±10. 9), (51. 4 ± 10. 4), Ps <0. 01]. The Gm scores were negatively correlated with the VI scores(r = -0. 15), while positively correlated with the scores of PSET and HC (r = 0. 47,0. 34, Ps <0. 01). Regression analysis showed that the Gm scores were positively correlated with the HC scores (β = 0. 14) and negatively correlated with the VI scores (β = -0. 15). Regression analysis also revealed a dependency between the Gm scores and the score of VC multiplied by PSET, VI multiplied by PSET, and HC multiplied by PSET (β =0. 12, -0. 04, -0. 23; Ps <0. 01). The path analysis showed that the PSET score as a mediator between the Gm scores and the scores of VI, HC, and VC. The model fit indices were x2/df= 1. 054, P = 0. 305, RMSEA = 0. 009, NFI = 0.997, RFI = 0. 984, M = 0.987, TLI = 0.969, and CFI = 0. 987. Conclusion: It suggests that maladjustment prevalence in armed police soldiers may be positively related with the military service time, and stress may play a mediating role between maladjustment and acculturation.%目的:探讨武

    Full Text Available L’exécution du jeune Inca Tupac Amaru en 1572 fut pour les Indiens du Pérou un véritable cataclysme. Il s’insérait dans un contexte particulier : celui de la vice-royauté du Pérou qui connaissait, depuis de longues années, une série de guerres et de complots. Au cœur de cet espace troublé, se trouvait un royaume néo-inca que la Couronne espérait vaincre par une politique du compromis. Toledo, envoyé pour faire rentrer le Pérou dans un ordre nouveau, avait marqué, dès le début de son gouvernement, son opposition au régime de Vilcabamba dont la seule présence fragilisait la légitimité du pouvoir du roi de Castille aux Indes. C’était donc la question des Justes Titres qui préoccupait Toledo, décidé à lutter activement contre la pensée de Las Casas. La mort d’un messager, envoyé pour négocier avec l’Inca, servit de prétexte à une attaque de Vilcabamba qui permit l’arrestation du jeune Tupac Amaru que le vice-roi décida de condamner à mort, en dépit de sa conversion au catholicisme. L’exécution marqua pour les Indiens la fin d’un monde, la fin d’un espoir et apparut comme l’ultime catastrophe, une répétition de la mort de l’Inca et des Dieux. De nombreux récits rapportent la détresse infinie des Indiens et la désapprobation quasi générale des témoins. Nous voudrions proposer ici une rapide analyse des différentes lectures du cataclysme et tenter de montrer que, pour Toledo, il s’inséra dans une politique claire et assumée. Outre la question idéologique, le vice-roi s’appuya sur des arguments sécuritaires et fit finalement de Tupac Amaru non un prince mais un simple délinquant de droit commun. Cette réécriture de l’Histoire permit d’instaurer une nouvelle définition de la politique espagnole au Pérou mais le cataclysme marqua les esprits et Tupac Amaru, loin d’être oublié, devint un symbole qui traversa les siècles jusqu’à aujourd’hui.La ejecución del joven

    xito de las mismas.Nowadays, olive orchards have a densities not higher than 330 trees/ha. The major cost correspond to harvest operations, which is very labour demanding. Recently, a new type of olive plantations with densities around 2.000 tress/ha has appeared. The major advantage of this type of plantations is their totally mechanised harvest, by vineyards straddle-harvesting machines. These plantations have a very early bearing and very productive, at least in the first years. The most common cultivar used is ‘Arbequina’. In the present work, data of the first four harvest of a variety comparative trial are reported. This trial include ‘Arbequina’, ‘Arbequina i-18’, ‘Arbosana’, ‘Koroneiki’, ‘Fs17’ y ‘UC 2-35’ cultivars. From the ‘Arbequina’ and ‘Arbosana’ had been the most productive and ‘UC 2-35’ the less vigorous. Results of a trial testing densities between 780 and 2580 trees/ha is also described. Up to now, the higher densities have been the most productive ones. However, more definitive results can be obtained in the coming years, when problems of competence among trees started to appear. In summary, as in the near future is expected that the subsides from the EU are going to be greatly reduced and the labour for harvesting is difficult to find, the ability to this type of plantations to be profitable at long term will determine their success.

    higher social capital are associated with higher happiness. (β = 0. 283 ; p 〈 0. 1 and β = 1. 219 ; p 〈 0. 01 ). Party membership, religious belief and social support have no relationship with happiness. Mo- reover, social capital affects happiness mainly through health. Thirdly, this paper discusses why different types of social capital have different relationships with health and happiness. Social trust can facilitate collective actions, provide more social services and disseminate health informa- tion to improve heath behavior. Social trust can also reduce psychological tress. Social participation can enable ru- ral elderly to integrate into society, obtain emotional support and identity, avoid isolation and slow down ageing process. This can help them keep healthy and happy. Religious belief has no effect on health and happiness. This is perhaps due to self-selection effect. Unhealthy people with incurable disease are more apt to have religious be- lief. This may cancel out the protective effect of religion. Social support has no effect on health and happiness. This may be due to the shortage of available resources and social norms of unwillingness to seek help from other people except family members. Party membership means both benefits and responsibilities. It can bring more resources to improve health status but also bring more psychological stress and reduce happiness. Based on empirical analysis, we put forward policy suggestions. First, government should increase the cover- age of pension system and health insurance system so as to provide solid basis for social participation of rural elder- ly. Special attention should also be given to the oldest old, disabled, widowed and empty nesters. Second, govern- ment should increase the investments into recreational facilities and provide conveniences for social predication. The community should also organize various activities to bring into full play of rural elderly into social participation. Third, government

    , chlorophyll content and leaf fresh and dry weight of plane saplings. Phosphorus content significantly increased in inoculated plants as compared to non-inoculated plants. It is recommended that in dry regions and water shortage conditions, the deficit irrigation method accompanied with mycorrhizal fungus inoculation to save water. Conclusion: Our data showed that mycorrhiza inoculations increased most growth parameters including leaf area, chlorophyll content and leaf fresh and dry weight of plane saplings. In conclusion, mycorrhiza inoculations can increase plant tolerance against drought stress by increasing phosphorus concentration, chlorophyll content, and photosynthesis rate. Generally, results of this study revealed that inoculation of plane tress with mycorrhizal fungi, improved plant growth under stress conditions through its positive influence on nutrients uptake, chlorophyll content and other growth parameters.

    Objective: To explore the effect of group counseling on self-esteem and achievement motivation in impoverished college students, analyze the effects towards students with different self-esteem and achievement motivation, and probe the intervention program for promoting their mental health and self-development Methods: Theoretically based on person-centered therapy, rational - emotive therapy (RET) and positive psychology, a developmental, structured, closed and homogeneous group counseling were designed. Forty-eight impoverished college students participated in the group counseling for 6 times. They were assessed with the Self-Esteem Scale (SES) and Achievement Motive Scale (AMS), Outcome Questionnaire (OQ) before and after the group counseling. Results: After the group counseling, the OQ total scores [(90. 0 ±24. 2) vs. (96. 7 ±20. 0)] and subscores of symptom dis- tress, interpersonal relationships, and social role were significantly decreased (Ps <0.01). The OQ total scores were significantly decreased in those with middle or high self-esteem and achievement motivation [ e. g., the total scores in those with middle self-esteem, (95. 8 ± 16. 9) vs. (99.1 ± 14. 9), Ps <0.05]. The OQ subscores of symptom distress, interpersonal relationships, and social role were decreased in those with high self-esteem and high achievement motivation [e. g., the subscores of symptom distress in those with high self-esteem, (30. 8 ± 5. 7) vs. (36. 3 ± 4. 8), Ps <0.05]. The OQ subscores of symptom distress, interpersonal relationships, and social role were decreased in those with middle achievement motivation [e. g., the subscores of symptom distress, (48. 9 ± 13.0) vs. (51. 7 ± 10. 8), Ps <0.05]. Among all the factors, only the scores of social role were decreased in those with middle self-esteem [(21. 9 ±3.0) vs. (23.4 ±3.1), P <0.01]. The middle self-esteem group's score was only decreased on the dimension of social role [(21. 9 ±3.0) vs. (23.4 ±3. 1), Ps <0. 001

    Full Text Available Introduction : La santé mentale positive est de plus en plus reconnue comme un élément central des politiques et des programmes en matière de santé publique. On a déterminé au Canada que le Continuum de santé mentale - Questionnaire abrégé (CSM-QA constituait un outil de mesure prometteur qu'il fallait intégrer aux enquêtes d'évaluation de la santé mentale positive de la population. Ce questionnaire vise à évaluer un modèle à trois facteurs de santé mentale positive : le bien-être émotionnel, le bien-être social et le bien-être psychologique. Cette étude a pour but de déterminer si le CSM-QA offre une mesure adéquate de la santé mentale positive des Canadiens adultes. Méthodologie : Nous avons réalisé une analyse factorielle confirmatoire (AFC à l'aide des données de l'Enquête sur la santé dans les collectivités canadiennes - Santé mentale de 2012 (ESCC-SM. Nous avons également effectué une validation croisée du modèle à l'aide des données de l'Enquête sur la santé dans les collectivités canadiennes - Composante annuelle (ESCC - Composante annuelle de 2011-2012. Nous avons examiné la validité reliée à un critère dans le cadre d'analyses de corrélation entre les scores des sous-échelles du CSM-QA et les concepts positifs (comme la satisfaction à l'égard de la vie et négatifs (comme la détresse psychologique associés. Résultats : Nous avons confirmé la validité du modèle à trois facteurs du bien-être émotionnel, social et psychologique dans le cadre d'une AFC de deux échantillons distincts, et ce, après avoir intégré les quatre erreurs corrélées entre les questions relatives à l'échelle du bien-être social. Nous avons observé, comme prévu, des corrélations significatives entre le bien-être émotionnel, psychologique et social et les concepts associés. Le coefficient alpha de Cronbach était de 0,82 pour les sous-échelles du bien-être émotionnel et du bien

Depuis la naissance de la victimologie (branche de la criminologie et l’intervention des grands noms de la victimologie, puis avec l’évolution socioculturelle et juridique sans cesse croissante, on a assisté à la prise en compte du profil de la victime comme étant un « élément clé » devant faire l’objet d’une attention accrue. L’Arme des Carabiniers (en raison notamment de sa dispersion sur tout le territoire s’inscrit dans ce nouveau contexte, en participant avec les autres acteurs institutionnels de la sécurité à cette « révolution culturelle », qui se traduit par une meilleure prise en compte de la victime. Expression d’une nouvelle orientation majeure du service, le concept de police de proximité est né de l’idée de rendre l’Arme plus visible et plus proche des citoyens. Ainsi, l’action de proximité s’efforce de combattre un fort sentiment d’insécurité, en exploitant les valeurs du Carabinier, étant généralement le premier interlocuteur des personnes en détresse. Pour une meilleure satisfaction des attentes de la population, le développement d’une culture de l’accueil des victimes constitue une priorité pour l’Institution et fait l’objet d’une attention particulière dans la formation de base et continue de l’ensemble des militaires de l’Arme, tous grades confondus. La victime (souvent physiquement et moralement traumatisée doit trouver en face d’elle un militaire, véritable professionnel chargé de son soutien et de son assistance, et toujours capable d’apporter des réponses empreintes d’humanité.

    métaphore d’un lieu féminin de l’emprisonnement en même temps que celle de la rébellion contre les règles patriarcales. Trente ans environ après la parution de Jane Eyre, une autre femme a publié un roman évoquant l’atmosphère obsédante de Thornfield Hall, à savoir l’écrivaine allemande, Eugenie Marlitt, auteur de Die zweite Frau (The Second Wife, 1874. Marlitt semble se réapproprier, tout en le réécrivant, le personnage de Bertha dans le contexte de la fiction domestique allemande. Les deux romans explorent en effet la thématique de la femme emprisonnée et marginalisée sur le plan social en termes d’ethnicité afin de montrer comment les rôles féminins et masculins sont inéluctablement liés aux relations de pouvoir. Dans Jane Eyre et Die zweite Frau, le motif de la maison est un élément central qui favorise la compréhension des personnages féminins, mais qui souligne surtout le mystère qui émane des maisons des deux romans, représentées par deux femmes, la Créole Bertha et l’Indienne Lotusblume, ce qui, au cœur de l’articulation de l’idée maîtresse des deux récits, révèle la construction à plusieurs facettes de la féminité.

    rendement de lait implique nécessairement une référence à sa productrice : la vache. Ici déjà, la question de genre est introduite. L’entretien du troupeau est la fonction de l’homme, tandis que l’exploitation du lait revient à la femme. Or cette fonction d’exploitation du lait assoit dans le même temps une liberté économique de la femme qui en est la propriétaire. Enfin cet article montre le pouvoir symbolique et social donné à la femme, affirmé par le lait maternel. Celui-ci est le vecteur des plus grandes qualités nécessaires à un « bon peul », mais peut aussi devenir la voie de transmission de pouvoirs maléfiques. Maîtresse du pouvoir lacté, la femme en hérite d’un statut particulier propre à la société peule.When milk becomes a social issue: the FulBe case in Burkina FasoThe question of breastfeeding as a factor of HIV transmission is a reason for interest in milk as a subject of research. Mother-child transmission of HIV is an important public health issue in the South. The successful implementation of preventive programmes requires different approaches, such as those of the social sciences. The perceptions which valorize breastfeeding are deeply rooted in the majority of ‘traditional’ societies, and these perceptions valorize in turn local perceptions of milk. In effect, in FulBe society, milk has a value which goes beyond the simple question of breastfeeding, being present at the very heart of the socio-economic structure. It is this aspect which constitutes the focus of this article.The FulBe’s word of milk also means ‘that which is the best’. Milk and its producers, cows, are the fundament of local socio-economic organization. Men are in charge of the care of the herd while women are concerned with the exploitation of milk. In this particular ethnographic case, milk provides women with the possibility of economic and social emancipation, because milk becomes the property of women as soon as they are married and they

    Objective To analyze the relevant factors of respiratory distress syndrome for premature infants and the risk factors of extrauterine growth restriction(EUGR)for the premature infants with respiratory distress syndrome. Methods All 153 premature infants with respiratory distress syndrome were selected as case group, and they were assigned to EUGR group and non-EUGR group on the basis of whether they had EUGR. 200 premature infants without respiratory distress syndrome were selected as control group during the same period. Clinical data of each group were observed and relevant factors were analyzed. Results Differences of incidence rates of EUGR and severe EUGR between the pre-mature infants with respiratory distress syndrome and those without respiratory distress syndrome were statistically sig-nificant (P<0.05). Incidence rates of gestational age, birth weight, multiple pregnancy rate, preventive application rate of PS,antenatal application rate of hormone,fetal distress or asphyxia,amniotic fluid aspiration,intrauterine in-fection, placenta previa/placental abruption, cesarean section, pregnancy-induced hypertension and ges tational dia-betes mellitus were relevant factors of respiratory distress syndrome for premature infants (P<0.05). Gestational age of less than 31 weeks, multiple pregnancy, time reaching total enteral nutrition, feeding intolerance, and time resuming birth weight were independent risk factors of EUGR for premature patients with respiratory distress syndrome (P<0.05). Antenatal application of hormone was the protective factor of EUGR for premature infants with respiratory dis-tress syndrome (P<0.05). Conclusion Young gestational age and multiple pregnancy are common risk factors of respi-ratory distress syndrome and EUGR for premature infants, and antenatal application of hormone has protective effect on the two diseases. Respiratory distress syndrome has obvious adverse effect on infants' extrauterine growth, and EU-GR for premature infants

    OBJECTIVE:To systematically review the efficacy and safety of misoprostol combined with 10% Calcium gluco-nate injection in the treatment of postpartum hemorrhage,and provide evidence-based reference for the clinical treatment. METH-ODS:Retrieved from PubMed,EMBase,Ovid,CBM,CJFD and VIP,randomized controlled trials (RCT) about misoprostol combined with 10% Calcium gluconate injection (test group) versus conventional oxytocin in the treatment of postpartum hemor-rhage were collected. Meta-analysis was performed by using Rev Man 5.2 software after data extract and quality evaluation by Co-chrane systematic review manual 5.1.0. RESULTS:Totally 7 RCTs were enrolled,involving 1254 pregnant women. Results of Me-ta-analysis showed,compared with conventional oxytocin,misoprostol combined with 10% Calcium gluconate injection can signifi-cantly reduce 2 h postpartum hemorrhage [MD=-76.76,95%CI(-105.73,-47.79),P<0.001],24 h postpartum hemorrhage [MD=-118.28,95%CI(-167.78,-68.78),P<0.001] and the incidence of postpartum hemorrhage [OR=0.19,95%CI(0.08, 0.46),P<0.001],and shorten the 3rd delivery process [MD=-3.52,95%CI(-4.20,-2.84),P<0.001],the differences were sta-tistically significant;there was no significant difference in the intraoperative hemorrhage [MD=-61.31,95%CI(-121.98,-0.64), P=0.05] and neonatal 1 min Apgar score [MD=0.10,95%CI(-0.38,0.59),P=0.67] in 2 groups. The incidences of chest dis-tress,breathlessness and stomach discomfort in test group were significantly higher than control group [OR=18,95%CI(2.42, 133.98),P=0.005],but it was mild,and there was no significant difference in the incidence of fver,chills and nausea,vomiting, diarrhea and other adverse reactions. CONCLUSIONS:Both the efficacy and safety of misoprostol combined with 10% Calcium gluconate injection in the treatment of postpartum hemorrhage are good. Due to low quality and small-scale of included studies, more large-scale and long-term follow-up studies with strict designed are required for

    capillaires (Ca communément rencontrés lors des opérations d’extraction pétrolière. Nous utilisons deux types de micromodèles mouillables à l’huile : le premier est basé sur une méthode de déposition innovante permettant d’obtenir des monocouches de billes de verre de taille micronique, tandis que le second est microfabriqué dans du verre à partir de réseaux poreux aléatoires générés informatiquement. Chacun des modèles utilise un schéma d’injection central dans une géométrie radiale, ce qui engendre une variation continue du nombre capillaire pendant le drainage. Nous menons tout d’abord une analyse du drainage à l’échelle globale du micromodèle en couplant analyse d’image et mesures de pression et de débit. Les paramètres de base tels que perméabilité, porosité et saturation résiduelle en huile des modèles sont extraits dans cette première phase. Nous exploitons ensuite les possibilités de visualisation offertes par les micromodèles transparents pour mener une analyse locale du phénomène d’invasion. Les saturations locales et la largeur de front sont mesurées en fonction du nombre capillaire local. De façon intéressante, du fait de la géométrie radiale, nos expériences permettent de tracer continûment les courbes de désaturation capillaire sur plusieurs décades. Comme inféré, mais jamais observé précisément, les mesures de diverses expériences se regroupent sur une courbe maîtresse pour un micromodèle donné. Nous observons cependant des différences notables entre les deux types de micromodèle. Ces observations sont discutées à la lumière des différences géométriques existant entre les deux micromodèles à l’échelle du pore.

    were 26 male and 20 female patients from (38-73) years of age at the mean of (63.3 ± 7.2) years. Adenosine stress echocardiography was performed by infusing the agent at 140 ug/(kg•min) in 6 minutes. The changes of segmental ventricular wall motion, electrocardiogram (ECG), clinical symptoms, blood pressure and heart rate were recorded. Positive 3D-ASE result was deifned by the time of left ventricular segment minimum contraction volume gradually extending. Coronary angiograph (CAG) was conducted at 2 weeks after 3D-ASE, positive CAG ifnding was conifrmed by at least one of three main branches with the stenosis≥50%. Results: There were 29/46 patients with positive CAG findings, 26 with positive 3D-ASE presentations and 8 with positive adenosines tress ECG. CAG showed that 48 coronary branches were positive and 90 were negative;3D-ASE indicated that 40 coronary branches were positive and 98 were negative. For 3D-ASE diagnosed coronary lesions, the overall sensitivity was 89.6%(26/29), speciifcity 76.5%(13/17), accuracy 84.8%(39/46). There were 36 branch lesions conifrmed by both CAG and 3D-ASE. For 3D-ASE determined coronary lesions, the sensitivity was 75%(36/48), speciifcity 95.6%(86/90), accuracy 88.4%(122/138). For 3D-ASE found single, double and three vessels diseases, the sensitivities were 60%(9/15), 88.9%(8/9) and 100%(5/5) respectively. The e occurrence rate of 3D-ASE side effect was 52.2%, there were usually slight symptoms without severe adverse reaction. Conclusion: 3D-ASE has the high sensitivity and speciifcity in CAD diagnosis, it is an non-invasive examination with slight side effect, and therefore, has an important application value in clinical practice.

    Full Text Available Preserving Earth’s biodiversity is one of the central challenges to global sustainability, and the task is complicated in developing countries by the need to avoid further compromising the ability of resource - dependent people to secure their livelihoods. The challenge is all the more daunting given the scarcity of resources available to the effort, necessitating reliable analyses of the role of human agency and the effects of various policy prescriptions. New sources of data and computational tools available to researchers over the past two decades have enabled the development of quantitative models of human agency in land change, including a special class known as spatially explicit models. This article explores advances in understanding human agency in land change in Madagascar in order to synthesize lessons learned and identify remaining challenges. It concentrates on the findings of a number of recent spatially explicit modeling efforts, identifying progress in accounting for human presence in the landscape. Other quantitative and qualitative studies point to the importance of a broad array of additional factors, particularly those reflecting interactions among agents. Bringing together the various perspectives on human agency in land change in Madagascar should enable them to better contribute to the formulation of policy that can balance protection of the island’s biodiversity with securing the livelihoods of the Malagasy people. RÉSUMÉ: La conservation de la biodiversité est l’une des pièces maîtresses de l’utilisation pérenne des ressources de la planète et la tâche est d’autant plus complexe dans les pays en voie de développement dans lesquels les moyens de subsistance des populations rurales sont étroitement liés à leur capacité d’accéder aux ressources naturelles. La tâche est aussi ardue que les ressources financières disponibles sont limitées, de sorte qu’il est important de bien comprendre comment

Ils ont été d'extraordinaires nageurs et traversaient les torrents en portant leur charge sur la tête ou à la main. 9. Ils ne constituèrent jamais des états organisés et unifiés mais d'authentiques seigneuries (behetrías dans lesquelles les groupes vivaient indépendamment les uns des autres. Ils n'ont formé de confédération que dans les cas de danger. Les villages étaient petits et les maisons circulaires avec une charpente de bois et un toit de paille. Chaque famille avait en moyenne trois enfants. 10. Comme tout groupe humain de culture marginal de (marginale non englobé dans un état organisé, ils ont été de grands défenseurs de la liberté pour laquelle ils se sont battus. Ils avaient des lances, des sabres, des dards, des flèches et des boucliers de bais et de peau, tout comme des poignards d'os. Durant les batailles, des hommes et des femmes combattaient dans la nación de Bagua. 11. À partir de 1549 tous ces groupes ethniques ont été répartis sous forme d'encomiendas et remis a plusieurs espagnols qui conquirent et s'approprièrent les terres de Jaén. 12.
