    Purpose. To evaluate the feasibility and safety of withdrawal of a Gunther tulip retrievable vena cava filter (GTF). Methods. Between June 2001 and December 2005, at our institution 86 GTFs were implanted for temporary caval filtration in 59 patients (37 women, 22 men; mean age 59.3 years, range 18-87 years). For GTFs retrieved thereafter, we retrospectively reviewed the following parameters: rate of success in retrieval, degree of trapped thrombus in the filter, and complications during retrieval. Results. Worsening of or new development of pulmonary embolism after filter implantation did not occur in any patient. Of the 86 GTFs implanted, retrieval of 80 was attempted. Among those 80 filters, 77 (96%) were successfully retrieved (with the standard method, n = 72; with the modified method, n = 5) without any complication. The period of implantation of the retrieved filters was 13.4 ± 4.2 days. In the 5 filters that were filled to a height of ≥ 1/4 with trapped thrombus, retrieval was performed after attempts were made to decrease trapped thrombi. In addition, a temporary filter or another GTF was temporarily placed at the cephalad level of the GTF during this removal procedure. Conclusion. GTFs can be retrieved in the majority of cases. Even when encountering situations in which the filter could not be removed using the standard method, withdrawal was possible in a high frequency of cases through various trials using modified methods

    Gunther's disease or congenital erythropoietic porphyria is a rare and severe disorder comprising cutaneous and haemolytic symptoms. Photocutaneous lesions are responsible for scleroderma-like calcifications and deformities of the extremities visible on X-rays. Hemolytic manifestations lead to diffuse major osteopenia. Soft tissue calcifications of the fingers can be seen even in young patients. One case reported here is the first illustration of intracranial calcifications located on dura-mater and calvarium.

    Wagner, A

    1980-01-01

    Gunther (1931) regarded the fact that a diminishing future labor force due to lack of demand leads to increasing unemployment at the present time as a paradox. The presumed connection between declining birth rates and rising unemployment in contrast to a rising birth rate and declining unemployment in a transition period of about 15-20 years is called a Guenther paradox. The author tries to explain the Guenther paradox by means of a macrodemoeconomic model with disequilibrium on the labor market. Clearly there is a relationship between birth rate and unemployment.

    Purpose. We evaluated the Gunther Tulip (GT) retrievable inferior vena cava (IVC) filter with regard to indications, filtration efficacy, complications, retrieval window, and use of anticoagulation. Method. A retrospective study was performed of 147 patients (64 men, 83 women; mean age 58.8 years) who underwent retrievable GT filter insertion between 2001 and 2005. The indications for placement included a diagnosis of pulmonary embolism or deep venous thrombosis with a contraindication to anticoagulation (n = 68), pulmonary embolism or deep venous thrombosis while on anticoagulation (n = 49), prophylactic filter placement for high-risk surgical patients with a past history of pulmonary embolism or deep venous thrombosis (n = 20), and a high risk of pulmonary embolism or deep venous thrombosis (n = 10). Forty-nine of the 147 patients did not receive anticoagulation (33.7%) while 96 of 147 patients did, 82 of these receiving warfarin (56.5%), 11 receiving low-molecular weight heparins (7.58%), and 3 receiving antiplatelet agents alone (2.06%). Results. Filter placement was successful in 147 patients (100%). Two patients had two filters inserted. Of the 147 patients, filter deployment was on a permanent basis in 102 and with an intention to retrieve in 45 patients. There were 36 (80%) successful retrievals and 9 (20%) failed retrievals. The mean time to retrieval was 33.6 days. The reasons for failed retrieval included filter struts tightly adherent to the IVC wall (5/9), extreme filter tilt (2/9), and extensive filter thrombus (2/9). Complications included pneumothorax (n = 4), failure of filter expansion (n = 1), and breakthrough pulmonary embolism (n = 1). No IVC thrombotic episodes were recorded. Discussion. The Gunther Tulip retrievable filter can be used as a permanent or a retrievable filter. It is safe and efficacious. GT filters can be safely retrieved at a mean time interval of 33.6 days. The newly developed Celect filter may extend the retrieval interval

    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.

    Purpose. To evaluate the efficacy and safety of Gunther tulip retrievable vena cava filter (GTF) implantation to prevent pulmonary embolism during intravenously administered thrombolytic and anticoagulation therapy and interventional radiological therapy for occlusive or nonocclusive deep venous thrombosis (DVT) of the lower extremity. Methods. We evaluated placement of 55 GTFs in 42 patients with lower extremity DVT who had undergone various treatments including those utilizing techniques of interventional radiology. Results. Worsening of pulmonary embolism in patients with existing pulmonary embolism or in those without pulmonary embolism at the time of GTF insertion was avoided in all patients. All attempts at implantation of the GTF were safely accomplished. Perforation and migration experienced by one patient was the only complication. Mean period of treatment for DVT under protection from pulmonary embolism by the GTF was 12.7 ± 8.3 days (mean ± SD, range 4-37 days). We attempted retrieval of GTFs in 18 patients in whom the venous thrombus had disappeared after therapy, and retrieval in one of these 18 cases failed. GTFs were left in the vena cava in 24 patients for permanent use when the DVT was refractory to treatment. Conclusion. The ability of the GTF to protect against pulmonary embolism during treatment of DVT was demonstrated. Safety in both placement and retrieval was clarified. Because replacement with a permanent filter was not required, use of the GTF was convenient when further protection from complicated pulmonary embolism was necessary

    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.

    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.

    Ethanol-blended gasoline has been used in Brazil for 20 years and, probably, is going to be more widely used in North America due to the MtBE environmental effects on groundwater. The potential impacts caused by the presence of ethanol in UST spills are related to the co-solvency effect and the preferential degradation of ethanol over the BTEX compounds. These interactions may increase the length of dissolved hydrocarbon plumes and the costs associated with site remediation. This study investigates the advantages of phytoremediation to overcome the problems associated with the presence of ethanol in groundwater contaminated with gasoline-ethanol mixtures. Experiments were performed under lab conditions with cuttings of Willow tree (Salix babylonica) cultivated hydroponically. Results showed that the cuttings were able to reduce ethanol and benzene concentrations by more than 99% in less than a week. The uptake of both contaminants was confirmed by blank controls and was significantly related to cuttings transpiration capacity. Sorption onto roots biomass also markedly affected the behavior of contaminants in solution. Experiments to evaluate plants' toxicity to ethanol indicated that plants were only affected when aqueous ethanol concentration reached 2000mgl{sup -1}. Results suggest that phytoremediation can be a good complement to intrinsic remediation in shallow aquifer sites contaminated with ethanol-blended gasoline spills. (Author)

    The effects of automotive exhausts gases on trees were observed along highway no. 4 in Fukushima. The observed trees were 319 Sophora Japonica (dog pagoda trees) planted on both sides of the highway covering about 4.5 km. The period of observation was between April 1973 through the end of this fall. The young leaves began to bud about April 10, opened about April 17th, and damage began to appear from about May 10; by July and August, damages such as discoloration, shrinking, tearing, and drying up progressed considerably. Some leaves were covered by dusts, as much as 10 wt% of the total weight of the leaves. The trees in the control areas in the suburbs showed almost no damage, except for some slight chlorosis. The chlorophyll measurements increased up to early July and decreased thereafter in the polluted area; the measurements were much higher in the control areas.

    Larval nematodes that parasitize the Mayan cichlid fish 'Cichlasoma (Nandopsis)' urophthalmus (Günther 1862) in southern Florida were identified as Contracaecum spp. (Nematoda: Anisakidae, Anisakinae). The objective of this study was to determine whether infection intensity and prevalence of these parasites differ between a brackish water and freshwater habitat or through ontogeny in the freshwater habitat only. The nematodes were removed from the abdominal cavity of the fishes and counted. Infection intensity was compared between habitats using analysis of covariance and evaluated through ontogeny using Spearman rank order correlation. Prevalence was compared between habitats and between adults and juveniles from the freshwater habitat using a z-test. Although infection intensity did not differ between habitats, infection prevalence was greater at the freshwater site (FWS). Both the prevalence and intensity of nematode infection increased through ontogeny at the FWS, and no nematode was found in fishes that were smaller than 93 mm standard length. Thus, the parasites appear to accumulate during the lifetime of the fishes.

    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 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 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.

    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.

    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 Pedostibes tuberculosus, the Malabar tree toad, was described 137 years ago from the Malabar region (now the coastal parts of Kerala of the Western Ghats. Since the description of this arboreal toad, not much information is available on the natural history, breeding habits and life cycle except for its description, range of distribution and advertisement call details. In the present account, the tadpole stages of this toad from Gosner tadpole Stage 21 to 45 are presented and the phytotelmatic mode of life of this toad has been confirmed by locating the tadpoles within the Ochlandra reed culm.

    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. La biomasa del guapote es relativamente baja. La especie presenta un ciclo de vida largo (8 a 10 años con una baja oscilación en el crecimiento (C= 0.3, la expectativa de vida máxima estimada fue de 12 años y el punto de mínimo crecimiento coincidió con el período de desove (entre Noviembre y Diciembre. 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.

    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 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.

    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 Excedence 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)

    Full Text Available Objective: To evaluate the bioaccumulation of heavy metals in Parachanna obscura (P. obscura and Clarias gariepinus (C. gariepinus and the use of their parasites as accumulation indicators from Lekki Lagoon. Methods: Samples of fish were procured from Oluwo market, a landing site of fish of artisanal fishermen in Epe. Metal accumulation, and intestinal parasites and protozoan of P. obscura and C. gariepinus were investigated. Sediment and water samples were examined for selected heavy metals (Cu, Cr, Ni, Pb and Fe while nematode parasite from infected fish were also analysed for heavy metal content. Results: Absolute morphometric parameters had low correlation with single independent morphometric index (total length and standard length but increased when correlated with combined indices. The prevalence of parasitic infections in P. obscura and C. gariepinus were 35% and 36% respectively. The metal concentrations accumulated in the fish’s liver were more than that found in the water and sediment. There was strong correlation in metal accumulated in the parasites relative to the water medium (r = 0.968 - 1.000, P < 0.01. Procamallanus spp., a nematode accumulated 2 times more Cu, Cr, Ni, Pb and Fe than Wenyonia sp. There was higher heavy metal level observed in intestinal nematode Procamallanus sp. than wenyonia sp. in the infected fish in this study. Conclusions: This suggests that Procamallanus sp. may be used as a potential sink of metal pollution in an aquatic environment and also a good sentinel in the environment.

    Full Text Available This study was carried out to investigate the reproductive aspects of the flying fish, Hirundichthys affinis Günther, 1866 considering their importance in the fish production of the Rio Grande do Norte State, Brazil. Fish samples were collected from the Municipality of Caiçara do Norte, northern coast of the state, during the period of April, 1999 to April, 2000. 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.

    It has been concluded that the process of growth and normal development of single-stratum pine tress at the age from 20 to 40 depends on their density. Under conditions of thick forest interspecific competition and fight for space sharpen. Within the estrangement area unfavorable trends in growth and evolution have been disclosed at the age above 30. Growing of pines without care results in suppression of growth; some morphological changes in the trunk form have been observed. Such an uncontrolled mode of growing can lead to physiological weakening of the tress. 8 refs.; 4 tabs

    2010-01-01

    Objective: To discuss the therapeutic efficacy and manipulation skill of Gunther Tulip retrievable inferior vena cava filter in interventional treatment for acute deep venous thrombosis of lower extremity. Methods: From September 2007 to April 2008, a total of 36 patients with acute deep venous thrombosis of lower extremity were treated in our hospital. The time of the onset of disease ranged from 1 day to 12 days. The precipitation causes included prolonged lying in bed due to surgery or bone fracture (n = 18) and postpartum (n = 5), while no obvious precipitation causes could be found in 13 patients. Pulmonary embolism was coexisted in 12 cases. Clinically, the affected limb was swelling and painful, the skin was cyan-purple or pale in color with higher skin temperature. The circumferential length of the affected thigh was 3-10 cm longer than that of normal side. Patients with coexisted pulmonary embolism had the clinical presentation of dyspnea, chest pain, hemoptysis, etc. Gunther Tulip retrievable inferior vena cava filter was implanted via femoral venous access or via right internal jugular venous access, which was followed by intravenous transcatheter thrombolysis. Vascular ultrasonography and angiography were performed 45-75 days after the treatment to confirm that there was no fresh or free thrombus in the veins of lower limb or in the pulmonary arteries. When it was confirmed, Gunther Tulip retrievable inferior vena cava filter was taken out via right internal jugular venous access, which was followed by inferior venacavography. After the procedure anticoagulation and antibiotic medication were employed for 3-5 days. A follow-up for 4-10 months was made. Results: A total of 36 Gunther Tulip retrievable inferior vena cava filters were successfully implanted by one procedure, the average time cost for the filter delivery was 1.5 minutes (0.5-5 minutes). During the delivery procedure, the amplitude of elastic displacement of filter was less than 2 mm. One

    Several quantities including modulus of elasticity, fracture stress, fracture strain, yield tress and yield strain, were calculated for cellulose tri acetate polymer. These samples were exposed to different gamma doses in the range from (32 kg y), and different energies of infrared pulsated laser of 5 watt power in the range (Zero to 9 j/cm 2). The changes in these parameters were found to be due to changes in degree of crystallinity of polymers.4 figs., 3 tabs.

    Stress is calculated routinely in atomistic simulations. The widely used microscopic stress formulas derived from classical or quantum mechanics, however, are distinct from the concept of Cauchy stress, i.e., the true mechanical tress. This work examines various atomistic stress formulations and their inconsistencies. Using standard mathematic theorems and the law of mechanics, we show that Cauchy stress results unambiguously from the definition of internal force density, thereby removing the...

    Full Text Available Ethephon alone and in a mixture with inorganic defoliants was used to defoliate apple nursery trees of three cultivars: Yellow Transparent, McIntosh and Jonathan. The mixture of ethephon with copper sulphate or magnesium chlorate defoliated the trees better than ethophon or inorganic defoliants used seperately in twice as high concentrations as in a mixture. The tress defoliated with the mixtures of defoliants suffered less from frost injury than those treated with only the inorganic defoliants.

    After having recalled that he already published a first set of theses about the atomic hazard in 1957, and a second one in 1959, the philosopher Gunther Anders proposes a new one in which he evokes various notions like carelessness, panic, and emotional reactions, the threat of nuclear on human life, the consequences of nuclear war on health as there will no nurses or doctors any more, the opposition to the fabrication of weapons, the risk associated with the victory of nuclear energy, the meaning of revolution, the fact that the so-called peace is a war

  16. Experimental observations of the microlayer in vapor bubble growth on a heated solid

    Koffman, L.D.; Plesset, M.S.

    1983-01-01

    Experimental measurements of microlayer formation and of the time history of microlayer thickness change have been obtained for nucleate boiling of water and ethanol. These detailed measurements were obtained using laser interometry combined with high-speed cinematography. The measurement technique is discussed in detail with emphasis on the difficulties encountered in interpretation of the fringe patterns. The measurements for water can be reasonably applied to the data of Gunther and Kreith, in which case it is concluded that microlayer evaporate alone cannot account for the increased heat transfer rates observed in highly subcooled nucleate boiling. It appears that microconvection must play at least an equal role

    Full Text Available This paper proposes a discussion about aspects of writing process, nowadays, in and out of school. It is inspired mainly in Gunther Kress ideas about multimodality and semiotic power. Considering our complex comunicational landscape, in which we can employ many technological resources and get different language effects, it is important to think about writing processes in the sense of increasingly significant multimodality levels. Schools can participate in this scenario by proposing reflection and practice on writing, contributing to the expansion of "semiotic power" of people, despite the emphasis that has been given to the ENEM (a national test to university entrance in brazilian high school.

    The purpose of this study was to report the prevalence of thrombus within a retrievable vena cava filter inserted prophylactically in major trauma patients referred for filter extraction. Between November 2002 and August 2005, 80 retrievable inferior vena cava filters (68 Optease and 12 Gunther-Tulip) were inserted into critically injured trauma patients (mean injury severity score 33.5). The filters were inserted within 1 to 6 (mean 2) days of injury. Thirty-seven patients were referred for filter removal (32 with Optease and 5 with Gunther-Tulip). The indwelling time was 7 to 22 (mean 13) days. All patients underwent inferior vena cavography prior to filter removal. There were no insertion-related complications and all filters were successfully deployed. Forty-three (54%) of the 80 patients were not referred for filter removal, as these patients continued to have contraindications to anticoagulation. Thirty-seven patients (46%) were referred for filter removal. In eight of them (22%) a large thrombus was seen within the filters and they were left in place, all with the Optease device. The other 29 filters (36%) were removed uneventfully.We conclude that the relatively high prevalence of intrafilter thrombi with the Optease filter may be explained by either spontaneous thrombus formation or captured emboli.

    Irradiated with different dosages of soft X-ray, pollen germinations of prunus baimang, pear kieffer, trifoliate orange and pummelo, were investigated immediately or several days later after irradiation. The results revealed that the pollens of these fruit tress had different sensitivites to soft X-ray and various responses to storage duration. Therefore, even to the same kind of pollen, irradiation with different optimal exposure doses, as well as pollination at different times during storage, should be adopted variously according to the different aims and methods of breeding programs.

    The detection throughout the year of latent and ILAR viruses in fruit tress by classical serological tests appear to be unreliable. We have developed RT-PCR tests for a reliable detection of latent and ILAR viruses in fruit trees. These assays were then simplified to allow the direct use of crude plant extracts instead of total RNA preparations, and the analyses of pooled samples. In this way, such RT-PCR protocols are suitable for a routine diagnosis of latent and ILAR viruses in fruit tree certification.

    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. © The Author 2013.

  4. Resonant Magnetization Tunneling in Molecular Magnets: Where is the Inhomogeneous Broadening?

    Science.gov (United States)

    Friedman, Jonathan R.; Sarachik, M. P.

    1998-03-01

    Since the discovery(J. R. Friedman, et al., Phys. Rev. Lett. 76), 3830 (1996) of resonant magnetization tunneling in the molecular magnet Mn_12 there has been intense research into the underlying mechanism of tunneling. Most current theories( V. Dobrovitski and A. Zvezdin, Europhys. Lett. 38), 377 (1997); L. Gunther, Europhys. Lett. 39, 1 (1997); D Garanin and E. Chudnovsky, Phys. Rev. B 56, 11102 (1997). suggest that a local internal (hyperfine or dipole) field transverse to the easy magnetization axis induces tunneling. These theories predict a resonance width orders of magnitude smaller than that actually observed. This discrepancy is attributed to inhomogeneous broadening of the resonance by the random internal fields. We present a detailed study of the tunnel resonance lineshape and show that it is Lorentzian, suggesting it has a deeper physical origin. Since the hyperfine fields are believed to be comparable to the observed width, it is surprising that there is no Gaussian broadening.

  5. Evaluation of subcooled critical heat flux correlations for tubes with and without internal twisted tapes

    International Nuclear Information System (INIS)

    Inasaka, F.; Nariai, H.

    1996-01-01

    Eleven correlations and models for critical heat flux (CHF) of subcooled flow boiling in water were evaluated. Both a direct substitution method (DSM) and a heat balance condition method (HBM) were compared in the evaluations. The HBM was recommended as a better prediction method in the present study. For straight tubes under uniform heating conditions, the correlations of the Gunther, Knoebel, modified Tong, W-2, and Tong-75, and also the Celata and Weisman-Pei models were confirmed to give reasonably good predictions. Among them, the Celata model was the best with respect to accuracy. For swirl flow under uniform heating conditions, Tong-75-I (involving modification of the water velocity parameter) and Nariai-Inasaka correlations were confirmed to give reasonably good predictions, even though their predictions were too low for the CHF under non-uniform heating conditions.

    The fishborne zoonotic trematode parasites (FZT) which cause liver and intestinal infections in humans are widespread in fish in Southeast Asia. Guangdong Province is the most important region for tilapia (Oreochromis niloticus) culture in China, but it is also an endemic region for FZT. To assess...... the potential for FZT transmission in an area with high density of tilapia farms, wild-caught fish from local rivers and canals were bought at local markets.

    Until the advent of plastinated cadavers, few outside the medical professions have had firsthand experience with human corpses. Such opportunities are now available at the Body Worlds exhibits of Gunther von Hagens. After an overview of these exhibits, we explore visitor responses as revealed in comment books available upon exiting the exhibit. Cultural, philosophical, and religious issues raised in the comments serve as a microcosm of society at large. The conclusion considers the challenge of such exhibits in introducing the public to science education, notes the image of the body as machine-so prevalent in the West-reflected in visitor comments, and finds hope that the exhibits promote, for many visitors, a sense of community among all humankind.

    Vena cava filters are an excellent tool for the prevention of pulmonary embolism (PE) in patients with deep vein thrombosis (DVT) of the lower limbs. However, these devices are not entirely free of complications as thrombi can develop inside them, threatening to occlude them completely. The objective of this report is to study the incidence of thrombosis in vena cava filters, as well as their impact on prognosis. We also mention the importance of CT as an imaging technique in the study of this complication. We present 30 patients in whom different filters were implanted and their prospective follow-up by means of CT over a mean follow-up period of 36 months. Chi-square analysis was used to determine whether there was a significant relationship among the complications encountered (p<0,05), and their course over time was studied by means of Kaplan-Meyer curves. Five cases (16%) of complete thrombosis of the filter were observed among patients in whom the Gunther model had been implanted, yielding an index of probability of complete permeability of the inferior vena cava at 13 months of 82%. Thrombi of different degrees (between 5% and 60%) were also observed inside the filter in ten patients (33%) with Gunther, Simon-Nitional and LGM models. Filter thrombosis was not significantly associated with the onset of recurrent PE or of venous disorders involving lower limbs, the relationship between PE and preimplantation presence of inferior vena cava thrombosis was significant (p<0.01). It was also observed that post implantation anti coagulation did not significantly prevent later onset of filter thrombosis. (Author)

    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.

    Résumé Les normes traditionnelles de genre prescrivent l’adéquation de l’expression de la masculinité et de la féminité au sexe anatomique de naissance. Les personnes qui présentent des variations dans l’expression de genre sont sujettes à diverses formes de réactions sociales suggérant la réprobation (des regards désapprobateurs aux violences physiques) susceptibles d’influencer négativement leur santé mentale. Trente-sept (37) jeunes se décrivant comme trans ou en questionnement sur leur identité de genre ont été recrutés dans le cadre de l’enquête sur les Parcours Amoureux des Jeunes de minorités sexuelles du Québec. Leurs expériences de victimisation parentale et de victimisation basée sur la non-conformité de genre ainsi que des indicateurs de santé mentale (détresse psychologique, estime de soi) ont été mesurés. Afin de comparer les expériences de victimisation et l’état de santé mentale des jeunes trans, ils ont été appariés à 37 garçons et 37 filles cisgenres sur la base de leurs caractéristiques sociodémographiques. Des analyses de prévalence et un modèle acheminatoire ont été réalisés. Les résultats mettent en évidence que les jeunes trans sont plus susceptibles de présenter des scores cliniques de détresse psychologique et de faible estime d’eux-mêmes que leurs pairs cisgenres. La violence verbale parentale et la victimisation basée sur la non-conformité de genre influencent négativement l’estime de soi, ce qui en retour augmente la probabilité de vivre de la détresse psychologique. Les résultats appuient l’importance des interventions de soutien à la diversité sexuelle et de genre. PMID:26966849

    Examiner le lien entre les conditions de travail et la santé mentale des travailleurs-euses de la restauration.MÉTHODE : L'échantillon se compose de 652 travailleurs-euses de la restauration issus de l'ESCC-SM de 2012. Des analyses de régression linéaire hiérarchique sont effectuées et ajustées en fonction de divers facteurs sélectionnés (sociodémographiques, habitudes de vie). Les conditions de travail sont mesurées en partie selon le Job Content Questionnaire (JCQ) de Karasek et Theorell. La détresse psychologique est mesurée à partir de l'échelle K6 de Kessler. La santé mentale positive est mesurée à partir du Continuum de santé mentale-version abrégée (MHC-SF) de Keyes.RÉSULTATS : Les fortes exigences psychologiques, le travail à temps partiel et les fortes exigences physiques sont associés de façon positive à la détresse psychologique des travailleurs-euses de la restauration, alors que le soutien social des collègues y est associé de façon inverse. Pour la santé mentale positive des travailleurs-euses de la restauration, l'insécurité d'emploi, les fortes exigences psychologiques et la faible latitude décisionnelle sont associées de façon négative tandis que le soutien social des collègues y est associé inversement. Cette étude souligne l'importance de considérer à la fois les aspects positifs et négatifs de la santé mentale. En effet, les facteurs associés à la santé mentale positive et à la détresse psychologique des travailleurs-euses de la restauration sont différents, voire associés en direction inverse.

Although work-for-pay is thought to have an overallpostiive impact on women's psychological well being, not all women equally experience this positiveeffect. The objective of this study is to assess the effect of transitions in employment status onchanges in psychological distress among women in two types of family setting: lone parent families andmarried couple families (including common-law unions. Using a framework which combines a longitudinaldesign with a structural equation modelling multigroup analysis, the current study indicates clearlythat the employment transitions and employment stability have no uniform effect on the mental healthof all mothers. Specifically, transition into employment offers a significant reduction in feelings ofdistress only among married mothers. Single mothers, in contrast are found to experience a significantincrease in the level of distress when they move out of employment.

    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...

    Besides the commonly considered pathway of radionulides into plant products, namely root uptake and surface deposition, another contamination process of edible parts of plants may occur when activity is intercepted by exposed plant surfaces and translocated within the plant into the fruit under consideration. This pathway seems especially relevant in case of fruit trees having large total leaf areas compared to the actual fruit surface. Besides the plant species and the nutritive element the most relevant parameters of the uptake and translocation efficiencies seem to be the age and the time and way of application, where these parameters include a number of sub-parameters. The present studies concern the translocation of cesium in apple tress from differently labeled plant parts into fruit in view of its possible contribution to fruit contamination

    Species identification and characterization in tropical environments is an emerging field in tropical remote sensing. Significant efforts are currently aimed at the detection of tree species, of levels of forest successional stages, and the extent of liana occurrence at the top of canopies. In this paper we describe our use of high resolution imagery from the Quickbird Satellite to estimate the flowering population of Tabebuia guayacan trees at Barro Colorado Island (BCI), in Panama. The imagery was acquired on 29 April 2002 and 21 March 2004. Spectral Angle Mapping via a One-Class Support Vector machine was used to detect the presence of 422 and 557 flowering tress in the April 2002 and March 2004 imagery. Of these, 273 flowering trees are common to both dates. This study presents a new perspective on the effectiveness of high resolution remote sensing for monitoring a phenological response and its use as a tool for potential conservation and management of natural resources in tropical environments.

    A mathematical model of 137 Cs migration in forest ecosystem contaminated due to the Chernobyl accident presented, which describes the behaviour of this radionuclide in the forest litter-soil system, tress, and forest animals. The model's parameters for different types of forest ecosystems are estimated and model's adequacy is tested through the use of independent experimental data. The sensitivity of the model's output variables is analyzed to variations in the most significant parameters. The differences in the seasonal and mean annual dynamics of 137 Cs concentration in muscles of roe deers and mooses are shown to be defined by specific features of the diets of these animals and variations in 137 Cs content in the main diet components [ru

    This paper reports on the structural design/analysis of a gas exhaust system at a nuclear facility used to investigate some aspects of current piping design procedures. Specifically the effect of using various stress measures including ASME Boiler and Pressure Vessel (B and PV) Code formulas is evaluated. It is found that large differences in local maximums tress values may be calculated depending on the stress criterion used. The effect of using an Equivalent Static Method (ESM) analysis is also evaluated by comparing its results with those obtained from a Response Spectrum Method (RSM) analysis. It is shown that a spectrum amplification factor (equivalent static coefficient greater than unity) of at least 1.32 must be used in the current application of the ESM analysis in order to obtain results which are conservative in all aspects relative to the RMS analysis

    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 μ c, pore pressure P 0 and stress shape factor Φ is studied. The paper draws the conclusion that the vertical increasing rate of the maximum principal stress σ is directly proportional to friction, and inversely to pore pressure P 0 and stress shape factor Φ; while the vertical increasing rate of the minimum principal tress σ is directly proportional to pore pressure P 0, inversely to friction μ c and stress shape factor Φ. This study is a try to invert the data of focal mechanism solutions for the complete stress tensor.

    the purpose of the dissertation is to develop a real time expert reactor protection system (ERPS) for operational safety of pressurized water reactor nuclear power plant. The system is developed to diagnose plant failures and for identification of plant transients (with and without scram). for this ERPS. probabilistic safety analysis techniques are used to check the availability and priority of the recommended safety system in case of plant accidents . the real- time information during transients and accidents can be obtained to asses the operator in his decision - making . Also, the ERPS is able to give advice for the reactor operator to take the appropriate corrective action during abnormal situations. The system model consists of the dynamic differential equations for reactor core, pressurizer, steam generator, turbine and generator, piping and plenums. The system of equations can be solved by appropriate codes also displayed directly from sensors of the plant. All scenarios of transients, accidents and fault tress for plant systems are learned to ERPS

    A viscous flow model based on the Navier-Stokes equation is developed to describe coke descending behavior in the 1/7-scaled-down experimental setup of an actual 75 t/h cooling shaft. It is found that the internal friction due to cokes viscosity significantly influences the descending behavior of cokes in the lower part of the shaft, while the external wall friction dominates the sluggish flow of the cokes in the shaft. An asymptotic friction coefficient expression is proposed for granular mixtures flowing along the shaft wall modified from normal wall tress, and the concept of bulk solid viscosity is introduced to describe the internal friction between coke particles. The results simulated by the present model are compared with those by the potential flow and the kinematic model without friction. The viscous flow model is quite good to simulate the bulk coke flow as the physically important frictions are engaged

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.

    To reveals the effects of tree species on polysaccharides content of epiphytic Dendrobium officinale. The polysaccharides content of D. officinale attached to living tress in wild or stumps in bionic-facility was determined by phenol-sulfuric acid method. There were extremely significant differences of polysaccharides content of D. officinale attached to different tree species, but the differences had no relationship with the form and nutrition of barks. The polysaccharides content of D. officinale mainly affected by the light intensity of environment, so reasonable illumination favored the accumulation of polysaccharides. Various polysaccharides content of D. officinal from different attached trees is due to the difference of light regulation, but not the form and nutrition of barks.

    Full Text Available Recent personal documentary works about major historical events of the twentieth century, e.g., World War II, the Holocaust and the 1956 Hungarian Revolution, offer their readers a rich and multifaceted narrative, or a history that is also "his story," "her story" and that of entire families, cohorts and communities. Often, these works are accompanied by visual artifacts such as photographs, family tress, maps etc., or supported by concise historical surveys. Thus these memoirs complete the work of historians with the lived experiences of the few that represent many. Such is the case with two 2013 books by Charles Farkas and Nick Barlay depicting their mid-twentieth century Hungarian families, one Christian and one Jewish, through two World Wars and the anti-communist uprising, culminating in their escape to the West and in the two authors looking back upon the Hungarian past of their families.

    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.

    2006-06-01

    Atmospheric aerosols interact directly in a great number of processes related to climate change and public health, modifying the energy budget and partly determining the quality of the air we breathe. In my PhD, I chose to study the perturbation, if not the aggravation, of the living conditions in Ile-de-France associated to aerosol transport episodes in the free troposphere. This situation is rather frequent and still badly known. To achieve my study, I developed the observation platform 'TReSS' Transportable Remote Sensing Station, whose instruments were developed at the Laboratoire de Meteorology Dynamique by the LiMAG team. 'TReSS' consists of a new high-performance 'Mini-Lidar' and of two standard radiometers: a sun photometer and a thermal infrared radiometer. The principle of my experimental approach is the synergy of the vertical Lidar profiles and the particle size distributions over the column, obtained by the 'Almucantar' inversion of sun photometer data. The new 'Lidar and Almucantar' method characterizes the vertical distribution by layer and the optical micro-physical properties of the local and transported aerosols. Firstly, I undertook the characterization of the Paris aerosol, mainly of anthropogenic origin. Their radiative properties were analyzed in the daily and yearly scales. Then, I conducted a statistical multi-year study of transport episodes and a two-week study case, representative of a succession of desert dust intrusion in Ile-de-France. My PhD work concludes by a study on the impact of biomass burning aerosols during the heat wave on August 2003. I study the impact of the transported aerosols into the local radiative budget and the possible consequences on the diurnal cycle of the atmospheric boundary layer. (author)

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.

Dissected body parts feature alongside whole-body plastinates with their life-like poses ranging from those with Renaissance motifs to others with highly contemporary themes. However, the exhibitions and their creator, Gunther von Hagens, have astounded many, including anatomists, some of whom find the unconventional display of human bodies unethical and offensive. The voyeuristic nature of Body Worlds and the uneasy balance between entertainment and education have proved problematic for anatomists. Von Hagens himself is a polarizing figure, pursuing his dream of "democratizing anatomy" with little regard for the conventions of academia. While valid ethical objections can be raised against some aspects of the exhibitions, we argue that wholesale rejection of them is unwarranted. In arriving at this conclusion we assess the ethical and educational issues involved. We divide the whole-body plastinates into four categories, ranging from those illustrating structural and functional relationships to those with artistic and humanistic aspirations rather than anatomical ones. We conclude that anatomists need to face up to the opportunities and challenges posed by the Body Worlds phenomenon, utilizing what is being presented to the general public and adapting this in teaching and research.

    Full Text Available New digital technologies not only “change language” (David Cristal, but also “upgrade” human intelligence making it perform new and uncommon operations. The present paper is an analysis and a survey of most prominent innovations in human intelligence, which are instigated by the latest digital information technologies. These innovations include, according to the point of view of outstanding specialists in contemporary digital technologies, such operations as multitasking, serendipity, connectivity, hypermodality, visuality, and cybersemiotic convergence of objective and virtual reality. The paper is based on the data presented in the publications of such outstanding “digital” specialists as Larry Rosen, Jay David Bolter, Steven Downes, Jay Lemke, Gunther Kress, Soren Brier, etc. In their works they particularly stress the impact of digital technologies and internet communication on all spheres of human activities, their role in the inner psychological and mental states, in professional and educational domain, as well as the importance of their investigation and a gap between the intensive development of digital technologies and their insufficient usage in scientific, didactic, social and cultural life. Special attention in the paper focuses on the tendency towards visualization in the global information flows and its role in information processing and knowledge transfer. The paper particularly stresses the fact that the impact of contemporary digital technologies on all spheres of human activities, including the intellectual one, needs further and profound investigation.

    Laminar flow in devices fabricated from soft materials causes deformation of the passage geometry, which affects the flow rate--pressure drop relation. For a given pressure drop, in channels with narrow rectangular cross-section, the flow rate varies as the cube of the channel height, so deformation can produce significant quantitative effects, including nonlinear dependence on the pressure drop [{Gervais, T., El-Ali, J., G\\"unther, A. \\& Jensen, K.\\ F.}\\ 2006 Flow-induced deformation of shallow microfluidic channels.\\ \\textit{Lab Chip} \\textbf{6}, 500--507]. Gervais et. al. proposed a successful model of the deformation-induced change in the flow rate by heuristically coupling a Hookean elastic response with the lubrication approximation for Stokes flow. However, their model contains a fitting parameter that must be found for each channel shape by performing an experiment. We present a perturbation approach for the flow rate--pressure drop relation in a shallow deformable microchannel using the theory of isotropic quasi-static plate bending and the Stokes equations under a lubrication approximation (specifically, the ratio of the channel's height to its width and of the channel's height to its length are both assumed small). Our result contains no free parameters and confirms Gervais et. al.'s observation that the flow rate is a quartic polynomial of the pressure drop. The derived flow rate--pressure drop relation compares favorably with experimental measurements.

    Plastination is an anatomical technique that consists of replacing the liquids and fat of specimens by reactive polymers through forced impregnation in a vacuum. These are then polymerized to achieve the final result. E12 sheet plastination involves epoxy resin impregnation of thin (2-4 mm) and ultra-thin (SciELO databases, and manual searches. After searching, 616 records were found using the online and manual searches (MEDLINE, n: 207; EMBASE, n: 346; SciELO, n: 44; Manual search: 23). Finally, 96 records were included in this review (after duplicates and articles unrelated to the subject were excluded). The aim of this work was to review the E12 sheet plastination technique, searching for articles concerning views of it, identifying the different variants implemented by researchers since its creation by Gunther von Hagens, and to identify its applications from teaching and research in anatomy to morphological sciences.

    Full Text Available Revision of orthopedic surgeries is often expensive and involves higher risk from complications. Since most total joint replacement devices use a polyethylene bearing, which serves as a weak link, the assessment of damage to the liner due to in vivo exposure is very important. The failures often are due to excessive polyethylene wear. The glenoid liners are complex and hemispherical in shape and present challenges while assessing the damage. Therefore, the study on the analysis of glenoid liners retrieved from revision surgery may lend insight into common wear patterns and improve future product designs. The purpose of this pilot study is to further develop the methods of segmenting a liner into four quadrants to quantify the damage in the liner. Different damage modes are identified and statistically analyzed. Multiple analysts were recruited to conduct the damage assessments. In this paper, four analysts evaluated nine glenoid liners, retrieved from revision surgery, two of whom had an engineering background and two of whom had a non-engineering background. Associated human factor mechanisms are reported in this paper. The wear patterns were quantified using the Hood/Gunther, Wasielewski, Brandt, and Lombardi methods. The quantitative assessments made by several observers were analyzed. A new, composite damage parameter was developed and applied to assess damage. Inter-observer reliability was assessed using a paired t-test. Data reported by four analysts showed a high standard deviation; however, only two analysts performed the tests in a significantly similar way and they had engineering backgrounds.

  7. The Crossroads of Plastination and Pilgrimage

    Full Text Available At the Singapore Science Centre in 2010, I went to Body Worlds, an exhibit set up by the Institute for Plastination, founded by Gunther von Hagens. As I later learned, he pioneered plastination—the art, science, and technique of preserving entire bodies and body parts for use in medical and anatomical research, exhibition, or both. A few months after, I made the decision to donate my body after death to the Institute under arrangements similar to that of a Living Will. In my visits to two other Body World exhibits in Germany and the Netherlands, I have seen organs perfectly preserved and had thoughts occur to me that one day, I may well be an exhibit specimen instead of an exhibit attendee. By establishing a connection with existing pilgrimage literature; and using a combination of thick description and pragmatic analyses; this paper puts forward the proposition that visits to these; and other similar; exhibits constitute a pilgrimage of and to the self. The paper also discusses the ethics and practical consequences of body donation; and evaluates the arguments for and against the body donation decision from the lenses of the person making the donation; the person’s significant others; and societal influencers. The paper concludes by suggesting take-off points in discussing the connection between plastination and pilgrimage; particularly in the contexts of intercultural communication and religious studies.

    Full Text Available Exhibition "BODY WORLDS" which are presented exhibits of human remains are presented all over the world and are a major problem for the modern man, as presented on the preparations of the human not only serve scientific research, are not transferred to the medical schools to educate future doctors, but they were made available to the general public in the form of commercial and ambiguous. The aim of this study was to assess the ethical commercialization of human corpses "BODY WORLDS" exhibitions. Individual approach to the problems presented the dignity and value of human remains after death, of course, strongly related to the professed worldview. In the exhibits can be seen in both the scientific interest anatomical structures, as well as desecrated human remains or beautiful by its functional perfection of the body, understood also in terms of art. The question of ethics determines the right to decide for themselves, on the other hand, allows you to protect bodily integrity even after death. "BODY WORLDS" exhibition goes for the moral and ethical boundaries. In terms of people Gunther von Hagens for plastination of human remains which became a very profitable business, and its current activities defined as "plastination business" should be firmly said about the lack of moral principles.

    Adults of 2 new species in 2 orders of acanthocephalans obtained from the intestines of terrestrial amphibians and reptiles collected between 1998 and 2004 in Vietnam are described here. Pseudoacanthocephalus nguyenthileae n. sp. (Palaeacnthocephala: Echinorhynchidae) was collected from 5 species of terrestrial amphibians: (1) the common Sunda toad Bufo melanostictus Schneider (Bufonidae); (2) Paa verucospinosa (Bourret); (3) Gunther's Amoy frog Rana guentheri Boulenger; (4) Taipei frog R. taipehensis Denburgh (Ranidae), and (5) the Burmese whipping frog Polypedates mutus (Smith) (Racophoridae); as well as from the Chinese cobra Naja atra Cantor (Reptilia: Elapidae) and house gecko Hemidactylus frenatus Dumeril and Bibron (Reptilia: Gekkonidae). Sphaerechinorhynchus maximesospinus n. sp. (Plagiorhynchidae: Sphaerechinorhynchinae) was isolated from a king cobra Ophiophagus hannah (cantor) (Reptilia: Elapidae). Cystacanths of Porrorchis houdemeri (Joyeux and Baer, 1935) Schmidt and Kuntz, 1967 (Plagiorhynchidae: Porrorchinae) obtained from the mesenteries of banded krait Bungarus fasciatus (Schneider) (Reptilia: Elapidae), a paratenic host, are reported for the first time. Keys to the species of Pseudoacanthocephalus and Sphaerechinorhynchus are included. Characteristic features distinguishing the new species from related taxa include: P. nguyenthileae has 15-19 (usually 16-18) proboscis hook rows, each with 5-6 hooks that progressively increase in length and size posteriorly. The largest, intermediate, and smallest proboscis hooks of S. maximesospinus are the middle, anterior, and posterior hooks, respectively; the proboscis and neck are enclosed in a membrane. Morphometric characteristics of P. nguyenthileae show host-related variability.

    Le paludisme d’importation est une affection de plus en plus fréquente en zone non endémique. Les formes graves représentent 10 % des cas de paludisme à Plasmodium falciparum. Au Maroc, plus de 50 cas de paludisme sont enregistrés chaque année dont 83 % à P. falciparum. Ont été inclus dans l’étude tous les patients ayant développé un paludisme grave, admis au service de réanimation durant la période comprise entre le 1er Novembre 2009 et le 31 décembre 2015. Les principales données épidémiologiques, les motifs d’admission, la prise en charge et l’évolution ont été étudiés. Treize patients sont retenus. L’âge moyen est de 31 ans. Tous les patients ont séjourné en afrique subsaharienne et étaient non-immuns. La chimioprophylaxie était adéquate dans 33% des cas. Le délai moyen entre le début des symptômes et l’instauration du traitement était de six jours. La parasitémie moyenne initiale était de 12 %. Les motifs d’admission en réanimation étaient un coma (15%), une convulsion (07%), une détresse respiratoire (07%), une prostration (07%), une insuffisance rénale (07%), un choc associé à un ictère et une acidose (07%) et enfin une insuffisance rénale conjuguée à un coma (07%). Tous les patients ont reçu un traitement par la quinine intraveineuse avec une dose de charge dans 100 % des cas. Le taux de mortalité était de 23 %. Les causes du décès étaient dues à la défaillance multi viscérale et au syndrome de détresse respiratoire aigu. La mortalité des formes graves du paludisme reste élevée. L’adéquation de la chimioprophylaxie associée à la précocité du diagnostic et du traitement permettrait d’améliorer significativement le pronostic de cette parasitose. PMID:28292141

  11. Cavitation in confined water: ultra-fast bubble dynamics

    2012-02-01

    In the hydraulic vessels of trees, water can be found at negative pressure. This metastable state, corresponding to mechanical tension, is achieved by evaporation through a porous medium. It can be relaxed by cavitation, i.e. the sudden nucleation of vapor bubbles. Harmful for the tree due to the subsequent emboli of sap vessels, cavitation is on the contrary used by ferns to eject spores very swiftly. We will focus here on the dynamics of the cavitation bubble, which is of primary importance to explain the previously cited natural phenomena. We use the recently developed method of artificial tress, using transparent hydrogels as the porous medium. Our experiments, on water confined in micrometric hydrogel cavities, show an extremely fast dynamics: bubbles are nucleated at the microsecond timescale. For cavities larger than 100 microns, the bubble ``rings'' with damped oscillations at MHz frequencies, whereas for smaller cavities the oscillations become overdamped. This rich dynamics can be accounted for by a model we developed, leading to a modified Rayleigh-Plesset equation. Interestingly, this model predicts the impossibility to nucleate bubbles above a critical confinement that depends on liquid negative pressure and corresponds to approximately 100 nm for 20 MPa tensions.

    A programme of radioecological investigations using a specially designed powerful accurate source of gamma radiation (32 kCi 137 Cs) has been initiated in our country to study the consequences of the acute forest irradiation. The irradiation has been carried out twice - in autumn (September, 1973) and in spring (May, 1977). Pine and birch sections of the forest 26-30 years old have been subjected to irradiation. Exposures during autumn and spring irradiation constitute 16 and 8 days, respectively. Forest irradiation has been carried out so as to form isodose sections of considerable square to have a sufficient amount of tress in every isodose section. Pine-trees that perished due to the effect of ionizing radiation have been counted. Presented are the data on pine trees that perished depending on the dose absorbed and new pine shoots one year old (shoots of 1978) depending on the dose in the second year after spring irradiation. The data on the damage of shoots and buds used as the indices of pine radiation damage have been used to forecast that LD 100 for the period of acute effects (4-5 years) in the case of spring irradiation is approximately 1.5-2 krad, i.e. the spring effect on pine trees is 2-2.7 times more radiosensitive, than in autumn. The supposition is made that doses absorbed (about 1-2 krad) are minimum lethal doses for coniferous forests when irradiating them in most radiosensitive phases

    In 1991 year investigations are made on a studying of the radionuclide distribution (CS-137 and Sr-90) through the main forest biogeocenose elements (a litter a mineral soil layer, overground trees parts) on 5 experimental objects of Gomel' region with a various contamination. Radiation characters of the objects are done. As compared with 1989 year cesium and strontium migration from tress into the litter and from the litter to the soil is shown. In the litter and upper soil layer (5 m) contents of Cs-137 and Sr-90 are 95 and 80% accordingly. The Sr-90 concentration in the wood and the isotope concentration change through yearly layers (1986-1991 years) are studied. Wood layers formed to the accident have a lesser cesium concentration, especially in the oax-tree. The highest Cs and Se translocation, into the wood is noted in the pine the lesse one in the oax-tree. Among all elements of the biogeocenose the highest Cs-137 concentration the litter has and then one-year-old shoots, needles, lives, the bark and the wood go on. Even on the sixth year after the accident Cs concentration in the wood was 20-30 times less, than the one in needes and one-year-old shoot of this year. 4 refs.; 5 tabs

    2011-01-01

    A new vegetation modeling concept for Building and Environmental Aerodynamics wind tunnel investigations was developed. The modeling concept is based on fluid dynamical similarity aspects and allows the small-scale modeling of various kinds of vegetation, e.g. field crops, shrubs, hedges, single trees and forest stands. The applicability of the modeling concept was validated in wind tunnel pollutant dispersion studies. Avenue trees in urban street canyons were modeled and their implications on traffic pollutant dispersion were investigated. The dispersion experiments proved the modeling concept to be practicable for wind tunnel studies and suggested to provide reliable concentration results. Unfavorable effects of trees on pollutant dispersion and natural ventilation in street canyons were revealed. Increased traffic pollutant concentrations were found in comparison to the tree-free reference case. - Highlights: → A concept for aerodynamic modelling of vegetation in small scale wind tunnel studies is presented. → The concept was applied to study pollutant dispersion in urban street canyons with avenue tress. → The wind tunnel studies show that modelling the aerodynamic effects of vegetation is important. → Avenue trees give rise to increased pollutant concentrations in urban street canyons. - Avenue trees in urban street canyons affect the pollutant dispersion and result in increased traffic exhaust concentrations.

    A field experiment has been conducted to measure the N2-fixation in six legume trees, namely Gliricidia sepium(F1), Sesbania sesban(F2), Caliandra tetragona(F3), Flemengia conges-7ta(F4), Acacia mangium(F5), and Leucena leucocephala (F6), using 15N techniques, e.g. the isotope dilution method. For this technique a reference tress, that is a non N2--fixing trees has to be used. In this experiment three reference trees were planted, but only one was used, which above ground growth was equal to the legyme trees. The reference tree chosen was Eucalyptus alba (R1). Data obtained from this experiment show that in general the legume trees have growth then the reference trees expressed, in dray weight of various plant parts and plants and total-N uptake (TN). At harvest some of the legume and reference tree have reached a 2.5 m height. The percentage of N2-fixation(%-fix) ranges from 50-70%. The highest %N-Fix was shown by Leucena leucocephala (F6) (70%N-Fix). High %N-Fix does not necessarily mean hgh N-Fix uptake(gn/tree)too. The N-Fix appears to be determined by the TN (gn/tree). The highest N-Fix was contributed by the leaves, which also has the highest percentage of total -N(%TN) compare to the other plant parts, i.e. roots, stem, and branches

    Full Text Available Self-efficacy is assumed to promote posttraumatic adaption, and several cross-sectional studies support this notion. However, there is a lack of prospective longitudinal studies to further illuminate the temporal relationship between self-efficacy and posttraumatic stress symptoms. Thus, an important unresolved research question is whether posttraumatic stress disorder (PTSD symptoms affect the level of self-efficacy or vice versa or whether they mutually influence each other. The present prospective longitudinal study investigated the reciprocal relationship between general self-efficacy (GSE and posttraumatic stress symptoms in 143 physical assault victims. We used an autoregressive cross-lagged model across four assessment waves: within 4 months after the assault (T1 and then 3 months (T2, 12 months (T3 and 8 years (T4 after the first assessment. Stress symptoms at T1 and T2 predicted subsequent self-efficacy, while self-efficacy at T1 and T2 was not related to subsequent stress symptoms. These relationships were reversed after T3; higher levels of self-efficacy at T3 predicted lower levels of posttraumatic stress symptoms at T4, while posttraumatic tress symptoms at T3 did not predict self-efficacy at T4. In conclusion, posttraumatic stress symptoms may have a deteriorating effect on self-efficacy in the early phase after physical assault, whereas self-efficacy may promote recovery from posttraumatic stress symptoms over the long term.

    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.)

    The investigation of effects evoked by reduction of immissions on the phytohormone balance in needles of conifers (ethylene, measured as ACC and MACC, abscisic acid and indole-3-acetic acid) is continued on the sites 'Edelmannshof' in the Welzheimer Wald (open-top chambers) and 'Stoeckerkopf' in the Northern Black Forest (under strong SO{sub 2}-impact until autumn 1987). On the site 'Edelmannshof', reduced immissions seem to exert positive effects on the phytohormone balance of the examined trees. Due to differences between individual tress subjected to the same treatment, it is not yet possible to decide, if there are really true effects on the phytohormone balance, which at 'Edelmannshof' is investigated over the period of only one year. On the site 'Stoeckerkopf' the obtained results point to a different behaviour of IAA-contents in needles of trees formerly subjected to SO{sub 2}-immissions and trees subjected to influences causing forest decline.

    Hair chemical treatments, such as dyeing and straightening products, are known to cause damage that can be assessed by protein loss. The aim of this study was to evaluate the hair protein loss caused by combined chemical treatments (dye and relaxer) using the validated bicinchoninic acid (BCA) method. Three kinds of straighteners, based on ammonium thioglycolate, guanidine hydroxide and sodium hydroxide, were evaluated and the least harmful combination indicated. Caucasian virgin dark brown hair tresses were treated with developed natural brown color oxidative hair dyeing and/or straightening commercial products based on ammonium thioglycolate, sodium hydroxide, or guanidine hydroxide. Protein loss quantification was assessed by the validated BCA method which has several advantages for quantifying protein loss in chemically treated hair. When both treatments (straightening and dyeing) were combined, a higher negative effect was observed, particularly for dyed hair treated with sodium hydroxide. In this case, a 356% increase in protein loss relative to virgin hair was observed and 208% in relation to only dyed hair. The combination of dying and relaxers based on ammonium thioglycolate or guanidine hydroxide caused a small increase in protein loss, suggesting that these straightening products could be the best alternatives for individuals wishing to combine both treatments. These results indicated that when application of both types of products is desired, ammonium thioglycolate or guanidine hydroxide should be chosen for the straightening process. © 2015 Wiley Periodicals, Inc.

    Earlier studies of ski injury indicated that youths were at increased risk of injury, that males were most likely to injure the head or face, and that females were most likely to injure the knee. To obtain information about safety knowledge and risk behaviour that might contribute to injury among young skiers and snow-boarders. Survey of knowledge and behaviour in injured and noninjured cohorts. Blackcomb Mountain, Whistler, British Columbia. A total of 863 noninjured and 118 injured skiers and snowboarders aged five to 17 years using Blackcomb during 1993/94. Skier Knowledge Inventory Questionnaire. The injured cohort had less knowledge of the Skiers Responsibility Code. In both groups, almost half had had no lessons, 31% had had bindings adjusted by nonprofessionals and chair lift safety bars were used one ride in four by children age 13 to 17 years. The injuried cohort wore helmets slightly less often. Both groups regularly skied through the trees (60% to 70%), and one-thirds had skied on closed runs. Excessive speed was identified as the major cause of injury. Skiers did not recognize jumping as contributing to injury. Lack of knowledge of safety rules was more prevalent among the injured cohort. Skiing without due care - including skiing through tress, skiing on closed runs, skiing with excessive speed and jumping, particularly by snowboarders - were identified as potential causes of injury.

    This paper describes the improved UO 2 thermal conductivity model for use in the ELESTRES (ELEment Simulation and sTRESses) computer code. The ELESTRES computer code models the thermal, mechanical and microstructural behaviour of a CANDU® fuel element under normal operating conditions. The main purpose of the code is to calculate fuel temperatures, fission gas release, internal gas pressure, fuel pellet deformation, and fuel sheath strains for fuel element design and assessment. It is also used to provide initial conditions for evaluating fuel behaviour during high temperature transients. The thermal conductivity of UO 2 fuel is one of the key parameters that affect ELESTRES calculations. The existing ELESTRES thermal conductivity model has been assessed and improved based on a large amount of thermal conductivity data from measurements of irradiated and un-irradiated UO 2 fuel with different densities. The UO 2 thermal conductivity data cover 90% to 99% theoretical density of UO 2 , temperature up to 3027 K, and burnup up to 1224 MW·h/kg U. The improved thermal conductivity model, which is recommended for a full implementation in the ELESTRES computer code, has reduced the ELESTRES code prediction biases of temperature, fission gas release, and fuel sheath strains when compared with the available experimental data. This improved thermal conductivity model has also been checked with a test version of ELESTRES over the full ranges of fuel temperature, fuel burnup, and fuel density expected in CANDU fuel.

    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.

    The Canada-France Redshift Survey (CFRS) is a collaboration between astronomers in Canada and France: Simon Lilly (University of Toronto), Olivier Le Fevre and Francois Hammer (Observatoire de Paris Meudon), David Crampton (Dominion Astrophysical Observatory, Victoria), Laurence Tresse (Cambridge University), and David Schade and Dan Hudon (University of Toronto). The survey is based primarily on observations with the 3.6m Canada-France-Hawaii Telescope (CFHT) on Mauna Kea, Hawaii. The CFRS consists of spectra of over 1000 faint objects selected to have 17.5 study of normal galaxies at redshifts z > 0.5, corresponding to look-back times of greater than 50% of the age of the Universe. Observations of CFRS galaxies have also been made with the Hubble Space Telescope and the survey will form the basis of future studies with a number of other ground-based and space facilities. We have written a lay-persons guide to the CFRS and the main scientific results that are emerging from it. (1 data file).

    Soil is a kind of discrete, multiphase compound that is composed of soil particles, liquid and air. When soil is disturbed by bulldozing plate, the mechanical behavior of the soil will become very complex. Based on the law of action and reaction, the dynamic mechanical behavior of disturbed soil was indirectly analyzed by measuring and studying the forces on the bulldozing plate by soil currently, so a stress-strain virtual measuring system for bulldozing plate, which was designed by the graphical programming language DASYLab, was used to measure the horizontal force Fz acting on the bulldozing plate. In addition, during the course of design, the experimental complexities and the interferential factors influencing on signal logging were analyzed when bulldozing plate worked, so the anti-jamming methods of hardware and software technology were adopted correlatively. In the end, the horizontal force Fz was analyzed with Error Theory, the result shown that the quantificational analysis of Fz were identical to the qualitative results of soil well, and the error of the whole test system is under 5 percent, so the tress-strain virtual measuring system was stable and credible

    Fatigue failures in piping systems occur, almost without exception, at the welded connections. In nuclear power plant systems, such failures occur predominantly at the socket welds of small diameter piping ad fillet attachment welds under high-cycle vibratory conditions. Nearly all socket weld fatigue failures are identified by leaks which, though not high in volume, generally are costly due to attendant radiological contamination. Such fatigue cracking was recently identified in the 3/4 in. diameter recirculation and relief piping socket welds from the reactor coolant system (RCS) charging pumps at a nuclear power plant. Consequently, a fatigue evaluation was performed to determine the cause of cracking and provide an acceptable repair. Socket weld fatigue life was evaluated using S-N type fatigue life curves for welded structures developed by AASHTO and the assessment of an effective cyclic stress range adjacent to each socket weld. Based on the calculated effective tress ranges and assignment of the socket weld details to the appropriate AASHTO S-N curves, the socket weld fatigue lives were calculated and found to be in excellent agreement with the accumulated cyclic life to-date

    Full Text Available Time management is an important skill that every student in higher education institutions should acquire since it is one of the key factors in assuring excellent achievement in academic. Students with poor time-management skills are far more likely to be tressed and, as a result, have a negative impact on the quality of life. Thus, this paper discusses this issue based on a study among students of Electrical, Electronic & System Engineering at Universiti Kebangsaan Malaysia according to year of study and then establishes the relationship with the student's academic performance. Data were collected using a set of questionnaire carried out on 272 undergraduate students from year one to year four for 2015/2016 session. These data were then analysed using ANOVA statistical inference and Pearson correlations. Results revealed that time management skills of the respondents were at moderate level and established a negative correlation with year of study. This study also found significant findings where time management skills have a positive but weak correlation with student’s academic performance. These findings suggest the need for additional research to further refine the justifications of these measures. The university is also anticipated to provide a good platform for students to develop their time management skills at the early stage of their admission to university.

    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.

    Understanding complex spatial and temporal patterns of drought-induced forest stress requires knowledge of the physiological drivers and ecosystem attributes that lead to or inhibit tree mortality. Prevailing meteorological conditions leading to drought may have lesser effect on vegetation that has evolved to avoid drought by accessing deeper soil moisture reserves or shallow groundwater to meet evapotranspiration demand. This is especially true in arid and semi-arid regions, yet groundwater use by trees is rarely explored in temperate systems and the extent to which groundwater use reduces drought vulnerability in these climates and regions is unknown. We explored responses of radial growth in temperate tress to wet and dry years across a depth to groundwater gradient from 1 to 9 meters in sandy forests in northern Wisconsin. The spatial patterns of tree growth in this watershed show areas where tree growth is influenced by depth to groundwater. Preliminary results showed trees in areas of shallower groundwater with low variability in tree growth and indicated that tree growth remains consistent during both wet and dry years. Conversely, trees in areas of deeper groundwater showed higher variability in tree growth during wet and dry years. We hypothesize that even in this humid region, the sandy soils do not retain sufficient moisture leading to potentially frequent water stress in trees and reductions in productivity. However, where and when accessible, we suspect trees use shallow groundwater to sustain evapotranspiration and maintain consistent growth during dry periods.

    The Logic Flowgraph Methodology (LFM) allows the construction of special graph models for simulation of complex processes of causality, including feedback loops and sequential effects. Among the most notable features of LFM is the formal inclusion in its models of causality conditioning by logic switches imbedded in the modeled process, such as faults or modes of operation. The LFM model of a process is a graph structure that captures, in one synthetic representation, the relevant success and fault space characterization of that process. LFM is very similar to an artificial intelligence expert system shell. To illustrate the utilization of LFM, an application to the assessment and on-line monitoring of a material control facility is presented. The LFM models are used to model adversary action and control response, and to generate mini-diagnostic and recovery trees in real time, as well as reliability tress for off-line evaluation. Although the case study presented is for an imaginary facility, most of the conceptual elements that would be present in a real application have been retained in order to highlight the features and capabilities of the methodology

    We consider the long underground constructions of deep and shallow types such as transport subways, mines, underground pipes etc. by the action of dynamic lads. Situated in areas of seismic activity, they are subjected to the influence of seismic waves during earthquakes and can be destroyed. Running loads inside constructions (transport for instance) affect upon toughness and stability of both subways and surrounding medium. If underground construction dispose near a day's surface, it acts also on nearby buildings. Evaluations of behavior of underground and pipes under dynamic influences in real conditions of usage are determined of stress state of constructions in the interaction with environment medium. Here underground constructions are simulated by infinitely long cylindrical cavities in utter ambience. As utter ambience the isotropic elastic medium and two-component medium of Biot are researched. Last one allows simulating saturated water oils. The elastic cylindrical shell simulates supporting of a tunnel (or pipeline). Both a tress state of construction and surrounding medium were investigated for a different contact conditions between support of tunnel and environment (rigid, slippery and viscous contacts).

    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

    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.

    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.

The organizing committee was formed by Uri Ascher, University of British Columbia, Richard Froese, University of British Columbia, Gary Margrave, University of Calgary, and Gunther Uhlmann, University of Washington, chair. The conference was part of the activities of the Pacific Institute of Mathematical Sciences (PIMS) Collaborative Research Group on inverse problems (http://www.pims.math.ca/scientific/collaborative-research-groups/past-crgs). This event was also supported by grants from NSF and MITACS. Inverse Problems (IP) are problems where causes for a desired or an observed effect are to be determined. They lie at the heart of scientific inquiry and technological development. The enormous increase in computing power and the development of powerful algorithms have made it possible to apply the techniques of IP to real-world problems of growing complexity. Applications include a number of medical as well as other imaging techniques, location of oil and mineral deposits in the earth's substructure, creation of astrophysical images from telescope data, finding cracks and interfaces within materials, shape optimization, model identification in growth processes and, more recently, modelling in the life sciences. The series of Applied Inverse Problems (AIP) Conferences aims to provide a primary international forum for academic and industrial researchers working on all aspects of inverse problems, such as mathematical modelling, functional analytic methods, computational approaches, numerical algorithms etc. The steering committee of the AIP conferences consists of Heinz Engl (Johannes Kepler Universität, Austria), Joyce McLaughlin (RPI, USA), William Rundell (Texas A&M, USA), Erkki Somersalo (Helsinki University of Technology

    Full Text Available O matrinxã (Brycon cephalus - Gunther, 1869, é uma espécie de peixe nativa da bacia Amazônica que tem despertado grande interesse entre pesquisadores e piscicultores de todo o Brasil. A crescente demanda pelo cultivo desta espécie em ambiente controlado se deve, principalmente, à sua pronta adaptação ao cativeiro e à aceitação de alimentos artificiais, tanto de origem vegetal quanto animal, ao lado do seu elevado valor comercial. Contudo, para ser um empreendimento comercial bem sucedido, o alimento a ser fornecido a esta espécie deve atender a suas necessidades em proteína e permitir elevados ganhos de peso em períodos curtos. O experimento foi conduzido na estação de aqüicultura da Embrapa Amazônia Ocidental. Foram testados cinco níveis de proteína bruta (16, 19, 22, 25 e 28% em dietas isocalóricas (EB = 390 kcal/100g em um delineamento experimental inteiramente casualizado com três repetições para cada tratamento. Os resultados obtidos após 210 dias de estudo mostraram que a dieta contendo 28 % de proteína bruta promoveu o maior ganho de peso, melhor conversão alimentar e mais alto crescimento corporal entre os níveis testados, indicando que este nível protéico atendeu satisfatoriamente às necessidades de proteína para esta espécie, nas condições deste experimento.Matrinxã (Brycon cephalus - Gunther, 1869 a native fish species from the Amazon basin, has been causing a great deal of interest among researchers and fish culturists all over Brazil. The rising demand for the culture of this species in controlled environment is mainly due, to its ready adaptation to captivity, the acceptance of manufactured feed made with either animal or plant ingredients, along with its high commercial value. However, for a successful commercial enterprise, feed must meet protein requirements of the fish to allow high weight gain in a short period.

    To compare the technical success of filter retrieval in Denali, Tulip, and Option inferior vena cava filters. A retrospective analysis of Denali, Gunther Tulip, and Option IVC filters was conducted. Retrieval failure rates, fluoroscopy time, sedation time, use of advanced retrieval techniques, and filter-related complications that led to retrieval failure were recorded. There were 107 Denali, 43 Option, and 39 Tulip filters deployed and removed with average dwell times of 93.5, 86.0, and 131 days, respectively. Retrieval failure rates were 0.9% for Denali, 11.6% for Option, and 5.1% for Tulip filters (Denali vs. Option p = 0.018; Denali vs. Tulip p = 0.159; Tulip vs. Option p = 0.045). Median fluoroscopy time for filter retrieval was 3.2 min for the Denali filter, 6.75 min for the Option filter, and 4.95 min for the Tulip filter (Denali vs. Option p Option p = 0.67). Advanced retrieval techniques were used in 0.9% of Denali filters, 21.1% in Option filters, and 10.8% in Tulip filters (Denali vs. Option p Option p Option filter when compared to both the Denali and Tulip filters. Retrieval of the Denali filter required significantly less amount of fluoroscopy time and use of advanced retrieval techniques when compared to both the Option and Tulip filters. The findings of this study indicate easier retrieval of the Denali and Tulip IVC filters when compared to the Option filter.

Changes of the uv inactivation of Escherichia coli K12 C600, E. coli B, Bacillus cereus, as well as E. coli phages lambda cb/sub 2/ and lambda b/sub 2/b/sub 5/ supplemented with azaderivatives prior to irradiation were investigated. It was found that I, II, III, IV, and VII are more, V and VI less sensitive to uv light compared with corresponding natural nucleic acid bases. Their changed uv sensitivities are reflected in the survival curves after uv irradiation in as far as azabases are incorporated into the nucleic acids in vivo. This explains the increase in uv sensitivity of E. coli K 12 C600, E. coli B, and B. cereus supplemented with I, II, III, IV, and VII and the decrease in uv sensitivity of Streptococcus faecalis supplemented with V (the latter information was taken from Gunther and Prusoff 1967). The lack of any significant influence of inactivation curves of E. coli K 12 C600 by V and VI, and on E. coli phages lambda cb/sub 2/ and lambda c/sub 2/b/sub 5/ by II, is discussed in terms of too small incorporation rates. No discrimination was put forward with respect to DNA and RNA incorporation.

    Copper indium selenide thin films of composition CuInSe2 with thickness of the order of 130 nm are deposited on glass substrate at a temperature of 423 ±5 K and pressure of 10-5 mbar using reactive evaporation, a variant of Gunther's three temperature method with high purity Copper (99.999%), Indium (99.999%) and Selenium (99.99%) as the elemental starting materials. X-ray diffraction (XRD) studies shows that the films are polycrystalline in nature having preferred orientation of grains along the (112) plane. The structural type of the film is found to be tetragonal with particle size of the order of 32 nm. The structural parameters such as lattice constant, particle size, dislocation density, number of crystallites per unit area and strain in the film are also evaluated. The surface morphology of CuInSe2 films are studied using 2D and 3D atomic force microscopy to estimate the grain size and surface roughness respectively. Analysis of the absorption spectrum of the film recorded using UV-Vis-NIR Spectrophotometer in the wavelength range from 2500 nm to cutoff revealed that the film possess a direct allowed transition with a band gap of 1.05 eV and a high value of absorption coefficient (α) of 106 cm-1 at 570 nm. Photoconductivity at room temperature is measured after illuminating the film with an FSH lamp (82 V, 300 W). Optical absorption studies in conjunction with the good photoconductivity of the prepared p-type CuInSe2 thin films indicate its suitability in photovoltaic applications.

  5. Sociologias do Direito: historicismo, subjetivismo e teoria sistêmica

    2005-11-01

    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.

  6. Big Web data, small focus: An ethnosemiotic approach to culturally themed selective Web archiving

    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.

    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. Copyright © 2016 Elsevier Ltd. All rights reserved.

    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

    The Bonneville Power Administration is proposing to fund the restoration of approximately 500 feet of streambank along the Yakima River at river mile 8, upstream of the Van Giesen Bridge on SR 224, in and between Richland and West Richland, Washington. This project will also result in the acquisition of Fox Island, a 12-acre island directly across the river from the restoration area. There is no development planned for the island. The proposed project includes: The installation of a bio-engineered streambank that incorporates barbs to capture silt and deflect flow, roughened rock or log toes, a riparian buffer, soil reinforcement, and bank grading. Long-term photo-point and plot sampling will also be implemented to evaluate the effectiveness and success of the restoration project. The NEPA compliance checklist for this project was completed by Darrel Sunday, a contractor with Sunday and Associates, Inc. (April 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 the pygmy rabbit, bald eagle, bull trout, Ute ladies'-tresses, and mid-Columbia Steelhead. The pygmy rabbit, bald eagle, and Ute ladies'Tresses are not known to occur in the immediate project vicinity, and it was determined that the proposed restoration project would have no effect on these species. It is difficult to determine if bull trout occur within the Tapteal project area and Dave Carl of the Washington Department of Fish & Wildlife was contacted and concurred with this assumption. It was determined that the project may affect, but is not likely to adversely affect bull trout, and the U.S. Fish & Wildlife Service has concurred with that determination (July 28, 2004). For the mid-Columbia Steelhead, an anadromous fish species, BPA has determined that if conducted in accordance with

    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

    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.

  13. 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.

    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.

    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.

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.

    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.

    Microcystins (MCs) are hepato toxins with a potent inhibitor activity of protein phosphatases P P1 and PP2A. These non-ribosomal peptides are getting more and more attention due to their acute toxicity and potent tumor-promoting activity. These toxins are produced by freshwater cyanobacteria. we report a toxicological study conducted on aquatic animal models such as the medaka fish. to date, the detailed mechanisms underlying the toxicity of microcystins are unknown. MC-leucine-arginine (MC-LR) is the most toxic and the most commonly encountered variant of MCs in aquatic environment. it has been used for toxicological investigations on the liver of intoxicated medeka. We performed differential proteome analyses of MC-LR - treated and untreated medaka fish in order to investigate the mechanisms of establishment of early responses to the toxin. The identification of proteins involved in these early responses might constitute candidates as bio markers of MC-LR exposure. Cytosolic proteins from livers of exposed or non-exposed medaka were resolved by 2D electrophoresis and detected using stains specific for phosphoproteins and for whole proteinaceous content. Overall, phosphoproteomic 2D maps. Of these 15 proteins, only two could not be identified by mass spectrometry. Among the other identified proteins, phenylalanine hydroxylase and keratin 18 (type I) showed variations in phosphoryl content in agreement with inhibition of PP2A activity after exposure of the fish to MC-LR. The other identified proteins exhibited variations in their expression level. The identified proteins appear to be involved in cytoskeleton assembly, cell signalling, oxidative w tress and apoptosis. The functional implications of responses to MC-LR exposure of these proteins are discussed. The methodology described in this report should be widely generalizable to a number of tissues and organisms, thus helping in the search for bio markers of MC-LR contamination

    Obesity and chronic stress are considered independent risk factors for the development of cardiovascular diseases and changes in autonomic system activity. However, the cardiovascular consequences induced by the association between high-fat diet (HFD) and chronic stress are not fully understood. We hypothesized that the association between HFD and exposure to a chronic variable stress (CVS) protocol for four weeks might exacerbate the cardiovascular and metabolic disturbances in rats when compared to these factors singly. To test this hypothesis, male Wistar rats were divided into four groups: control-standard chow diet (SD; n = 8); control-HFD (n = 8); CVS-SD (n = 8); and CVS-HFD (n = 8). The CVS consisted of repeated exposure of the rats to different inescapable and unpredictable stressors (restraint tress; damp sawdust, cold, swim stress and light cycle inversion). We evaluated cardiovascular function, autonomic activity, dietary intake, adiposity and metabolism. The HFD increased body weight, adiposity and blood glucose concentration (∼15%) in both control and CVS rats. The CVS-HFD rats showed decreased insulin sensitivity (25%) compared to CVS-SD rats. The control-HFD and CVS-HFD rats presented increased intrinsic heart rate (HR) values (∼8%). CVS increased cardiac sympathetic activity (∼65%) in both SD- and HFD-fed rats. The HFD increased basal HR (∼10%). Blood pressure and baroreflex analyzes showed no differences among the experimental groups. In conclusion, the present data indicate absence of interaction on autonomic imbalance evoked by either CVS or HFD. Additionally, HFD increased HR and evoked metabolic disruptions which are independent of stress exposure.

    An eight-week feeding trial followed by an acute combined stress test of low-salinity and nitrite were performed to evaluate effects of chlorogenic acid (CGA) on growth performance and antioxidant capacity of white shrimp Litopenaeus vannamei. Shrimp were randomly allocated in 12 tanks (30 shrimp per tank) and triplicate tanks were fed with a control diet or diets containing different levels of CGA (100, 200 and 400 mg kg(-1) feed) as treatment groups. Growth performance including weight gain (WG), biomass gain (BG), feed conversion ratio (FCR), and feed intake were determined after feeding for 56 days. Antioxidant capacity were evaluated by determining the activity of total antioxidant status (TAS), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), catalase (CAT) as well as the gene expression of GSH-Px and CAT in the hepatopancreas of shrimp at the end of feeding trial and again at the end of the combined stress test. The results indicated that supplemention of CGA had no significant effects on the growth performance and the activities of TAS, SOD, GSH-Px and CAT in hepatopancreas of shrimp cultured under normal conditions for 56 days. However, compared with the control group, CGA (200, 400 mg kg(-1) feed) significantly improved the resistance of L. vannamei against the combined stress of low-salinity and nitrite, as indicated by the significant (P shrimp treated with CGA in the combined tress test. Our findings suggested that CGA possessed dual-modulatory effects on antioxidant capacity of L. vannamei and could be a potential feed additive that can enhance shrimp resistance against environmental stresses. The recommended application dosage is 200 mg kg(-1) and further studies are needed to clarify the action model of CGA efficiency. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Introduction La démence peut retentir lourdement sur les aidants familiaux du patient. Les objectifs de notre étude étaient de déterminer le niveau de fardeau et de la dépression chez les aidants familiaux de sujets déments, et d'identifier les facteurs associés à un niveau de fardeau élevé. Méthodes Il s'agissait d'une enquête auprès de 65 aidants tunisiens. Les niveaux de fardeau et de la dépression ont été évalués par, respectivement, l'inventaire de Zarit et l’échelle de Beck. Résultats Le taux des aidants qui avaient un niveau de fardeau élevé était de 52,3 %. Une dépression modérée ou sévère a été relevée chez 46,2 %. Un niveau de fardeau élevé était corrélé, du côté de l'aidant, avec le niveau socio-économique moyen à élevé, la cohabitation avec le patient, le fait d’être son conjoint, la réduction des activités quotidiennes et la sévérité de la dépression, et, du côté du dément, avec l'agressivité. Conclusion Les facteurs corrélés à un niveau de fardeau élevé orientent vers les cibles d'intervention et sont susceptibles d’être améliorés par la prise en charge, ce qui contribuerait à alléger la détresse des aidants.

    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

    Decision tress have long been popular in classification as they use simple and easy-to-understand tests at each node. Most variants of decision trees test a single attribute at a node, leading to axis- parallel trees, where the test results in a hyperplane which is parallel to one of the dimensions in the attribute space. These trees can be rather large and inaccurate in cases where the concept to be learned is best approximated by oblique hyperplanes. In such cases, it may be more appropriate to use an oblique decision tree, where the decision at each node is a linear combination of the attributes. Oblique decision trees have not gained wide popularity in part due to the complexity of constructing good oblique splits and the tendency of existing splitting algorithms to get stuck in local minima. Several alternatives have been proposed to handle these problems including randomization in conjunction wiht deterministic hill-climbing and the use of simulated annealing. In this paper, we use evolutionary algorithms (EAs) to determine the split. EAs are well suited for this problem because of their global search properties, their tolerance to noisy fitness evaluations, and their scalability to large dimensional search spaces. We demonstrate our technique on a synthetic data set, and then we apply it to a practical problem from astronomy, namely, the classification of galaxies with a bent-double morphology. In addition, we describe our experiences with several split evaluation criteria. Our results suggest that, in some cases, the evolutionary approach is faster and more accurate than existing oblique decision tree algorithms. However, for our astronomical data, the accuracy is not significantly different than the axis-parallel trees.

    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.

A discussão sugere que, nas representações de seus respectivos APA, as quais apontam para os usos que fazem das TIC em suas práticas de aprendizagem, incluindo plataformas de redes sociais, já legitimamente aceitas em seu repertório de recursos de apoio ao trabalho escolar, os jovens não parecem apresentar usos surpreendentes de artefatos digitais. De fato, os desenhos aparentam ser caracterizados pela ausência de ações criativas e formas de engajamento produtivo com seu entorno imediato e com o mundo: os jovens parecem posicionar-se, predominantemente, como receptores, sugerindo que suas apropriações dessas tecnologias na aprendizagem são fortemente mediadas por elementos de uma cultura escolar tradicional e hierarquizada. Ao sugerir um cenário que parece marcado pela reprodução de relações usuais da educação bancária, fundamentada na pedagogia da transmissão, a discussão aponta para limites da utilidade da categoria nativos digitais, desafiando expectativas prometeicas e descontextualizadas do potencial transformador das TIC.

    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

    Anatomists are regarded as custodians of cadaveric material donated to science. Almost every facet of medical science has experienced explosive advances. This has impacted directly on anatomists and their role. Increasingly, anatomists are raising concerns with regard to the treatment of human tissue (Jones,2002, Clin. Anat. 15:436-440). The Korperwelten (Bodyworlds) of Gunther von Hagens et al. (1987, Anat. Embryol. 175:411-421) has evoked considerable debate about the treatment of human cadavers. Thus far clinical anatomists have had little role to play in policy formulation, legislation, and ethical imperatives as applied to cadaveric donation for organ transplantation. Anatomists play an even more negligible role in the raging ethical controversy around live related/unrelated organ transplantation. Due to the critical international shortage of cadaveric donors, boundaries are being pushed to meet the needs of potential recipients (Ohler,2001, Prog. Transplant. 11:160-161). Constant reappraisal of these ethical and moral issues is therefore appropriate. Issues that relate to cultural and economic imperialism and pronouncements of international transplant societies may also require re-evaluation. The legislature governing the donation of human tissue in various countries is usually governed by a Human Tissue Act or its equivalent. In general, such acts are congruent with the Human Tissue Act (South Africa: Government Gazette 9, November 2001; No. 22824) that states "It is an offense to charge a fee in relation to the donation of human organs." In many countries, however, various lay press report that "the sale of body parts is now coming of age." Terms such as "rewarded gifting" and "donors" being transformed into "vendors" are opening a Pandora's Box (Nelson et al.,1993, "Financial incentives for organ donation: a report on the UNOS ethics committee payment subcommittee"). Cameron and Hoffenberg (1999, Kidney Int. 55:724-732) feel strongly that arguments in

    Résumé Objectif Offrir aux médecins de famille un résumé des recommandations fondées sur les données probantes pour guider les soins aux survivantes traitées pour le cancer du sein. Qualité des données Une recherche documentaire a été effectuée dans MEDLINE entre 2000 et 2016 à l’aide des mots-clés anglais suivants : breast cancer, survivorship, follow-up care, aftercare, guidelines et survivorship care plans, en se concentrant sur la revue des lignes directrices publiées récemment par les organismes nationaux de cancérologie. Les données étaient de niveaux I à III. Message principal Les soins aux survivantes comportent 4 facettes : surveillance et dépistage, prise en charge des effets à long terme, promotion de la santé et coordination des soins. La surveillance des récidives ne se traduit que par une mammographie annuelle, et le dépistage d’autres cancers doit suivre les lignes directrices basées sur la population. La prise en charge des effets à long terme du cancer et de son traitement aborde des problèmes courants tels la douleur, la fatigue, le lymphœdème, la détresse et les effets indésirables des médicaments, de même que les préoccupations à long terme comme la santé du cœur et des os. La promotion de la santé met en relief les bienfaits de l’activité chez les survivantes du cancer, avec l’accent mis sur l’activité physique. Les soins aux survivantes sont de meilleure qualité lorsque divers services et professionnels de la santé participent aux soins, et le médecin de famille joue un rôle important dans la coordination des soins. Conclusion Les médecins de famille sont de plus en plus souvent les principaux fournisseurs de soins de suivi après le traitement du cancer du sein. Le cancer du sein doit être considéré comme une affection médicale chronique, même chez les femmes en rémission, et les patientes profitent de la même approche que celle utilisée pour les autres affections chroniques en

    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.

Il faut signaler l’influence de la phrénologie. Ces médecins définissent des stigmates physiques et moraux propres à la pratique de la pédérastie, surtout passive et à l’occasion définissent un personnage type. Ces discours relèvent d’abord d’une phraséologie morale et ils puisent leurs racines antérieurement. Cependant il faut aussi replacer ces discours stigmatisant la pédérastie passive dans le contexte de la construction de la virilité moderne.

    Biodiversity mapping in African savannah is important for monitoring changes and ensuring sustainable use of ecosystem resources. Biodiversity mapping can benefit from multi-spectral instruments such as WorldView-2 with very high spatial resolution and a spectral configuration encompassing important spectral regions not previously available for vegetation mapping. This study investigated i) the benefits of the eight-band WorldView-2 (WV-2) spectral configuration for discriminating tree species in Southern African savannah and ii) if multiple-images acquired at key points of the typical phenological development of savannahs (peak productivity, transition to senescence) improve on tree species classifications. We first assessed the discriminatory power of WV-2 bands using interspecies-Spectral Angle Mapper (SAM) via Band Add-On procedure and tested the spectral capability of WorldView-2 against simulated IKONOS for tree species classification. The results from interspecies-SAM procedure identified the yellow and red bands as the most statistically significant bands (p = 0.000251 and p = 0.000039 respectively) in the discriminatory power of WV-2 during the transition from wet to dry season (April). Using Random Forest classifier, the classification scenarios investigated showed that i) the 8-bands of the WV-2 sensor achieved higher classification accuracy for the April date (transition from wet to dry season, senescence) compared to the March date (peak productivity season) ii) the WV-2 spectral configuration systematically outperformed the IKONOS sensor spectral configuration and iii) the multi-temporal approach (March and April combined) improved the discrimination of tress species and produced the highest overall accuracy results at 80.4%. Consistent with the interspecies-SAM procedure, the yellow (605 nm) band also showed a statistically significant contribution in the improved classification accuracy from WV-2. These results highlight the mapping opportunities

    Full Text Available Introduction : Cette revue systématique a permis de recenser des enquêtes sur les jeunes représentatives de la population et comportant des questions sur la maltraitance envers les enfants déclarée par ces derniers. Nous avons également examiné la qualité des données et les questions d’ordre éthique pertinentes pour la collecte de données sur la maltraitance. Méthodologie : Nous avons effectué une recherche dans diverses bases de données en ligne pour sélectionner les articles publiés entre janvier 2000 et mars 2016 qui contenaient des données représentatives de la population mesurant la maltraitance envers les enfants. Les critères d’inclusion ont été établis a priori et deux examinateurs ont évalué indépendamment l'un de l'autre les articles pour s’assurer que les critères étaient respectés et pour vérifier l’exactitude des données extraites. Résultats : Au total, 73 articles portant sur 71 enquêtes ont répondu aux critères d’inclusion. Nous avons relevé diverses stratégies visant à assurer l’exactitude des renseignements et à atténuer la détresse des participants à l’enquête. Conclusion : L'ampleur des efforts déployés pour mesurer la prévalence de la maltraitance envers les enfants est le reflet de l'importance accordée à cette dernière à l'échelle de la planète. Malgré des connaissances incomplètes en matière de pratiques exemplaires liées à l’éthique et de qualité des données, il est possible de recueillir efficacement auprès des jeunes eux-mêmes des données sur la maltraitance dont ils font l'objet.

    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 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

Based on Gunther Kress’s theory of literacy, the perspective of multimodality was employed to gain better understanding of how creative learners portray practical experience and recognize meaning in transformation. The study recruited 20 master’s students studying creative arts. They were divided into discussion groups (media arts, performance arts and visual arts, in which they engaged in self-narratives related to creative learning. Then, the similarity principle was used in the paper to identify four dimensions: “preparatory experience,” “the brewing of ideas through time,” “group mentality,” and “creative association”. The research results revealed that self-exploration was particularly important, as was enduring uncertainty in the creative process and making productive use of the

    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

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.

Le systeme considere est forme d'un gaz d'electrons en interaction faible avec les impuretes de l'echantillon. Le modele du gaz d'electrons consiste en un gaz bidimensionnel d'electrons sans spin expose perpendiculairement a un champ magnetique uniforme. Ce dernier est decrit par le potentiel vecteur vec{rm A} defini dans la jauge de Dingle ou jauge symetrique. Conformement au formalisme de la seconde quantification, l'hamiltonien de ce gaz est represente dans la base des etats a un-corps de Dingle |n,m> et exprime ainsi en terme des operateurs de creation et d'annihilation correspondants a_sp{ rm n m}{dag} et a _{rm n m}.

    transects, hundreds of trees were screened and and about 100 candidate selected for grading. Of these, 65 were confirmed as plus trees and acquired from owners. 200 scions collected from the tree were grafted onto makau rootstock at Tiva Nursery in Kitui. 188 hedges were then established at Tiva to be used as source of material for clonal orchards and further work. The potential for improvement of productivity and value for farmers is very high. The variation and selection differential between selected populations and the rest of populations was estimated at 20%. Capturing this differential and establishing clonal orchards for seed production will improve quality and production of M. volkensii. Subsequent implementation of melia breeding strategy will involve establishment of clonal seed orchards using selected plus tress, progeny and genetic tests for the selected plus trees to confirm their worth. Range-wide genetic tests of the species will assist in differentiating populations refining of the breeding population

    Full Text Available Par son mariage en 1759 avec Louis-François-Joseph de Bourbon-Conti, Marie-Fortunée d’Este (1731-1803, fille du duc italien François III d’Este de Modène, devient princesse du sang en France. L’heureuse conservation de ses comptes permet d’étudier sa garde-robe et de réfléchir aux modalités du paraître vestimentaire à la cour de la fin du XVIIIe siècle. Tenir son rang à Versailles passe pour la princesse par des dépenses élevées, le port d’étoffes luxueuses et le choix de marchands réputés. Cette étude de cas invite au-delà à envisager la spécificité de l’apparence à la cour d’une princesse devenue en 1776 une épouse séparée au budget limité. Elle interroge également les contraintes physiques de l’habit de cour à la lumière des nouvelles valeurs de confort et de liberté, tout particulièrement pour une femme d’âge mûr et maladive qui ne paraît plus guère dans le monde aulique.To be received at court: the clothes of Mary Fortunate d'Este, Princess of Conti (1731-1803 - Aurélie Chatenet-Calyste is a French researcher and also teaches at the University of Champagne-Ardenne.

Several countries addressed the IAEA for assistance in commencing, or expanding, nuclear power programmes. Ministers also emphasized the importance of the highest nuclear safety levels, the highest level of security of nuclear material and facilities, conforming to international non-proliferation objectives and the management of spent fuel and radioactive waste. France, as the host government, had consultations with a number of Member States, and the Final Statement prepared for the Conference President reflected a broad convergence of views from the vast majority of participants expressed at the conference. It includes widespread support for the development and use of nuclear power for electricity production, water desalination, hydrogen production and other purposes. Developing countries identified their needs and expectations in the use of nuclear power, and it was recognized that the IAEA can support and assist them in investigating their needs, and the steps necessary to adopt nuclear energy, while understanding that each State is free to define its own energy policy. The IAEA was recognized as having an essential role to play in facilitating the development and use of nuclear energy with due regard to the issues of safety, security and non-proliferation, in fostering international cooperation and in information dissemination on nuclear power to the public. The importance of international research and development programmes in the development of innovative nuclear systems, to enable nuclear power to thrive, was emphasized.

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.

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.

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

    , 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.

    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.

    Directory of Open Access Journals (Sweden)

    1987-01-01

    Full Text Available Le bassin des 'Couches Rouges' de Sicuani (sud du Pérou est un bassin continental intramontagneux dont le fonctionnement débute dès les premiers mouvements tectoniques andins du Sénonien. La sédimentation est essentiellement d'origine fluviatile. Les termes les plus proximaux sont représentés par les rivières en tresse à galets et les plus distaux par la plaine d'inondation à chenaux divagants. Le sens constant des apports sédimentaires implique une paléopente régionale inclinée vers le nord. A cette époque, la principale source des sédiments n'est donc pas représentée par la Cordillère orientale mais plutôt par les reliefs situés au sud-ouest des affleurements. Le taux de sédimentation relativement élevé, le guidage des transits sédimentaires par d'anciennes failles majeures et l'existence de structures de déformation synsédimentaire compressives font du bassin de Sicuani un bassin tectoniquement actif, comparable à celui de Cuzco. La première phase tectonique andine ne correspond donc plus à un événement ponctuel mais bien au contraire à un continuum tectonique en compression au cours duquel se développe la sédimentation des 'Couches Rouges' sud péruviennes. Ce continuum tectonique est associé à une activité volcanique intermittente, en partie responsable de l'alimentation des bassins. La cuenca de las 'Capas Rojas' de Sicuani (sur del Perú es una cuenca continental intramontañosa cuyo funcionamiento empezó desde los primeros movimientos tectónicos andinos del Senoniano. La sedimentación tiene un origen fundamentalmente fluviátil. Los términos más proximales corresponden a ríos en trenza con cantos y los más distales a la llanura de inundación con canales divagantes. La permanencia del sentido de los aportes sedimentarios implica la existencia de una paleopendiente regional inclinada hacia el norte. Es así como, en esta época, la fuente principal de los sedimentos no estuvo representada por

    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.

    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

    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

K3, Albien supérieur, formée de faciès de chenaux distributaires en tresses répond à la phase d’ouverture généralisée rapide du Golfe de Gascogne. L’analyse tectonique comparée révèle des analogies géodynamiques de ces bassins en limites de plaques divergente obliques, dextre pour le bassin de Santa Rosalia et sénestre pour Mendibelza. La géométrie de ces bassins transtensionnels est celle de demi-grabens obliques aux failles principales du stade Rift, subissant un basculement en échelon. La sédimentation des deux bassins analysés est caractérisée par des faciès de fandelta, qui ont enregistré une partie de l’évolution du Golfe de Gascogne (formation de Mendibelza et du Golfe de Californie (Bassin de Santa Rosalia pendant la phase Synrift, puis Syn-rift tardif et transition Rift à Drift.Se presenta un análisis comparativo de la cuenca transtensional de Santa Rosalía, asociada a la apertura del Golfo de California Mioceno-Reciente por un lado, y de la cuenca antigua, Jurásico-Cretácico de Mendibelza, formada en los Pirineos occidentales por la apertura del Golfo de Vizcaya. Este estudio es una contribución a la comprensión de la sedimentación y los controles de las cuencas transtensionales localizadas sobre márgenes divergentes oblicuos actuales no deformados, con el objeto de utilizar esos modelos y compararlos para interpretar mejor y comprender el funcionamiento de cuencas antiguas creadas en contextos geodinámicos similares, pero tectonizados. Los sedimentos de la cuenca de Santa Rosalía registraron las diferentes etapas de su evolución paralela a la formación del rift oblicuo del Golfo de California desde el Mioceno superior. Aplicando las nociones de la estratigrafía secuencial, encontramos 3 secuencias: la secuencia T1 (Mioceno superior-Plioceno inferior que representa la fase syn-rift constituida de facies de abanico deltaico; la

    Full Text Available 1. Historiography is about the observation of changes. Even in a history of the moment, there has to be a before and an after. There is no history without event, without the difference perceived and described as "time". Legal history has to do with changes in the law. The law of some arbitrarily chosen point in time is examined and judged on the basis of what is new, what has changed, and what has remained the same. That has to be recognized and described before looking at the reasons why it has changed, and why it has changed in this particular way rather than in some other way. 2. Historians predominantly use "development" as the paradigm for explaining changes. "Development" means both continuity and change, upholding tradition and breaking with it, structure and event. The paradox of simultaneous identity and alterity is familiar not only to historians, but is the basis of observation of all biological and social phenomena. In the field of natural sciences, the theory of evolution has long been applied to this issue. In the meantime, however, it has also been tested increasingly as means of observing social phenomena. 3. Sociologists (among them Niklas Luhmann, Dirk Baecker, Rudolf Stichweh have paved the way for social sciences based on a theory of evolution. This approach has also found its way into the field of law, especially -- surely no coincidence -- modern business law (Gunther Teubner and Marc Amstutz. Economists have also realised that the market can be described in terms of evolutionary theory (Thorsten Hens, H.H. Nau. Even literary criticism has begun to apply evolutionary theory (Hans-Ulrich Mohr, Gerhard Plumpe. Given the spread of this approach, hopes have been expressed that a universal theory "conceived as a consistent theory of evolution" (Wolfgang Frühwald might alleviate the lack of communication between the natural sciences and the arts. 4. In historiography, on the other hand, including legal history, evolutionary

İntihar amaçlı ateşli silah yaralanmasında silahın yerleşimi belirtilen şekilde olan 574 ölümde, olay yerinin tıbbi araştırmacı tarafından incelenmesi ve cesedin San Antonio,Teksas’taki Bexar Bölge Tıbbi Araştırma Ofisince yapılan otopsisi derlenerek hazırlanmıştır. 76 olguda silahın yeri belirlenememiştir. Geri kalan 498 olgunun %24’ünde silah cesedin elindedir. ■%69’unda silah cesedin üzerinde veya elinde olmamak üzere yanında bulunmuştur (cesede değer pozisyonda veya vücuduna 30 cm. mesafede. Geriye kalan %7 olgudaysa silah cesetten 30 cm.den daha uzakta bulunmuştur. Tabancalar göz önüne alındığında, silahların %25 7’si kişilerin elinde bulunmuştur. Uzun namlulu silah kullananlarda, olguların %19-5’inde silah ölenin elinde bulunmuştur. Eğer kişi ateş ettiği anda yatıyor ya da oturuyorsa silahın elinde kalma olasılığı daha büyüktür. Kişinin cinsiyeti, yara lokalizasyonu ve tabancanın kalibresi gibi değişkenler intihar amaçlı bir ateşli silah yaralanmasında silahın elde kalıp kalmayacağını tahmin etmekte belirleyici değildir.

Ces groupes avaient des pâturages et des auquénidés ils tissaient la laine et le coton. L'habillement était constitué par des chemises dont les dimensions variaient d'une nación à l'autre. Il en était de même pour la coiffure qui allait des tresses les plus longues à la coupe totale de la chevelure. 7. Un caractère culturel particulier a certains d'entre eux (Nehipe, Perico et Bagua était le salut effectué en léchant la main de la personne reçue. Ils parlaient plusieurs langues dont la plus commune était le patagon. 8. Ils préféraient se déplacer en utilisant des pirogues plutôt que des sentiers et savaient construire des ponts suspendus de lianes. 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.
