    Fifty-seven wild boars (Sus scrofa) from protected regions of Iran were examined for helminths. Sixteen species of helminths were collected; there were ten nematodes, one acanthocephalan, two trematodes and three larval cestodes. New host and distribution records were established for all helminths except of Taenia solium cysticerci. Wild boar shared nine of these helminths with domestic pigs, six with ruminants and three with human beings in Iran. Metastrongylus pudendotectus and M. salmi are reported for the first time from Iran.

    2015-07-01

    Between January and December 2013, the dental and periodontal health of 99 Swedish wild boars (Sus scrofa) was investigated. Sampling occurred in conjunction with routine hunting at six large estates in the southern and middle parts of Sweden. All six of the estates use supplemental feeding. The weight of the animals, their sex and their dates of death were noted. Age was estimated using tooth eruption and tooth replacement patterns. The oral cavity was inspected and abnormalities were recorded on a dental chart modified for wild boars. The findings included supernumerary teeth, absence of teeth, mild class II malocclusion, severe tooth wear, periodontitis, calculus, caries, tooth fractures and the presence of enamel defects. Swedish wild boars suffer from different dental lesions and the impact of supplemental feeding on dental and periodontal health is still to be investigated. Copyright © 2015 Elsevier Ltd.

    2018-01-01

    Feral pigs (Sus scrofa L.) are perhaps the most abundant, widespread, and economically significant large introduced vertebrate across the Pacific island region. Unlike many other nonnative invasive species, feral pigs have both cultural and recreational importance in the region, complicating their management. Today, Pacific island feral pigs are a mixture of several strains of domestic swine, Asiatic wild boar, and European wild boar. Due to their generalist diet and rooting behavior, feral pigs alter soils and watersheds and negatively impact native and nonnative flora and fauna. As a result, feral pigs have played a role in the extinction of several species of plants and animals on Pacific islands and have negative effects on both ecotourism and agricultural industries in the region. Despite numerous published studies on feral pigs in the Pacific island region, of which the majority include systematic analyses of original empirical data, some fundamental aspects of feral pig ecology remain poorly characterized, at least partly due to the remote and inaccessible environments that they often inhabit. To address these knowledge gaps, effort should be made to integrate research conducted outside the Pacific island region into local management strategies. This review summarizes the origins, history, ecology, environmental effects, and current management of feral pigs in the Pacific island region; integrates regional scientific findings with those of other insular and continental systems; and identifies current knowledge gaps requiring further research to inform the ecology and management of this impactful invasive species.

  10. Evaluation of different soil parameters and wild boar (Sus scrofa [L.] grassland damage

    Full Text Available Presented in this paper are the correlations between different soil parameters [presence of grubs, earthworms, pH, content of P2O5, K2O and organic matter (OM in soil] and wild boar (Sus scrofa [L.] damage to grasslands. The soil samples and damage assessments were performed at six locations in the Kočevje region, which is a densely wooded part of South East Slovenia. A significant positive correlation was discovered between the extent of damage due to wild boar rooting in grasslands and the number of grubs (r=0.73, the weight of grubs (r=0.69 and the content of P2O5 (r=0.87 in the soil. The quantity and weight of grubs in soil were significantly influenced by soil pH, the content of CaCl2 (r=0.71/0.72, P2O5 (r=0.90/0.91, and OM (r=0.74/0.77; while the quantity and weight of earthworms in soil were influenced by the content of K2O (r=0.81/-0.84. A moderate yet insignificant correlation (r=0.48/0.56 was discovered between the number and weight of earthworms in soil and the extent of grassland damage. Grubs represent a more important source of protein for wild boars than earthworms; consequently, reducing the quantity of grubs in soil could minimise the extent of damage caused by boars.

    The number and spatial distribution of wild boars (Sus scrofa) has increased remarkably in Sweden as well as in other European countries. To understand the population dynamics of the wild boar, knowledge of its reproductive period, oestrus cycle and reproductive success is essential. The aim of this study was therefore to describe the seasonal reproductive pattern and reproductive potential of a wild boar population in Sweden. The study was based on findings from macroscopic examinations of the reproductive organs from 575 hunter-harvested female wild boars (>30 kg body weight). Samples were collected between December 2011 and December 2015 in the southern and middle parts of Sweden. The age of the sampled animals was determined and dressed weight was noted. The stage of the reproductive cycle was defined according to ovarian structures and in relation to the appearance of/and findings in the uterus. The crown-rump length (CRL) of the embryos/foetuses was used to calculate the oestrus/mating month and month for the expected farrowing. The macroscopic examination revealed a seasonal variation of reproductive stages, although cyclic and pregnant females were found in all seasons. Moreover, the estimated oestrus/mating and farrowing months based on the CRL showed that mating and farrowing may occur 'off-season'. The average litter size (no. of embryos or foetuses) per pregnant female was 5.4. Sow weight and age had significant effect on both the reproductive potential (ovulation rate and litter size) and pregnancy rate, respectively. The reproductive potential in the studied wild boar population was high compared to studies from other countries and farrowing may occur 'off-season'. This suggests that the environmental conditions in Sweden, including supplemental feeding, are favourable for wild boar reproduction.

    Full Text Available Habitat use by wild boar Sus scrofaz was examined during a three-year period in Moncayo Nature Park, a protected mountain area in the Iberian mountain system, Spain. Tracking indirect signs of activity was used to collect data on the species occurrence, according to vegetation type, topography, hunting activity, and season. The data were analysed using binary logistic regression. Habitat used by wild boar differed according seasons, management practices, and vegetation. Main selected habitats were at medium elevations (1,101-1,600 m in areas dominated by holm oak (Quercus ilex, beech (Fagus sylvatica and oak woods of Q. robur, Q. petraea and Q. pyrenaica. Non-hunting areas were selected over hunting areas. We found a seasonal variation in the habitat use of wild boar, with areas dominated by holm oak being used disproportionately in spring, and areas at medium elevations selected only during summer. The results also support the view that non-hunting areas provide a refuge for this species inside the protected area.Estudiamos el uso del hábitat por parte del jabalí Sus scrofa a lo largo de tres años en el Parque Natural del Moncayo, un área protegida de montaña en el Sistema Ibérico, España.

    The Indian wild pig (Sus scrofa cristatus) is a protected species and listed in the Indian Wildlife (Protection) Act, 1972. The wild pig is often hunted illegally and sold in market as meat warranting punishment under law. To avoid confusion in identification of these two subspecies during wildlife forensic examinations, we describe genetic differentiation of Indian wild and domestic pigs using a molecular technique. Analysis of sequence generated from the partial fragment (421bp) of mitochondrial DNA (mtDNA) cytochrome b (Cyt b) gene exhibited unambiguous (>3%) genetic variation between Indian wild and domestic pigs. We observed nine forensically informative nucleotide sequence (FINS) variations between Indian wild and domestic pigs. The overall genetic variation described in this study is helpful in forensic identification of the biological samples of wild and domestic pigs. It also helped in differentiating the Indian wild pig from other wild pig races. This study indicates that domestic pigs in India are not descendent of the Indian wild pig, however; they are closer to the other wild pig races found in Asia and Europe.

    We used serology to estimate the prevalence of exposure to chlamydiae in Italian populations of wild boars (Sus scrofa). Sera from 173 hunter-killed wild boars harvested during the 2006-2009 hunting seasons in three Italian regions were tested for antibodies to Chlamydia suis, Chlamydophila pecorum, Chlamydophila abortus, and Chlamydophila psittaci by the microimmunofluorescence test. Antibody titers to chlamydiae ≥ 1:32 were detected in 110 of the 173 samples tested (63.6%). Specific reactivity could be assessed only in 44 sera with antibody titers to C. suis that were two- to threefold higher than antibody titers against the other chlamydial species; the other 66 sera had similar reactivity against all the chlamydia species tested. Antibody to C. suis was detected in sera from wild boar populations with rare or no known contact with domestic pigs. These results suggest that the wild boar could be a chlamydia reservoir and may acquire chlamydiae independent of contacts with the domestic pig.

Such analysis methods as determination of water-binding capacity (WBC and pH values, microstructural studies, proteome methods, mass spectrometric methods, high performance liquid chromatography (HPLC and determine the concentration of cathepsin D, calpain 3 and myoglobin were applied in current study. DFD meat was characterized by high pH (6.2 and WBC (93.18%, while PSE - low pH (5.5 and WBC (79.19%. pH and WBC values in NOR pork was medium and averaged 5.9 and 92.05%, respectively. Microstructural studies revealed that fiber in exudative pork was the least and averaged 39.7 µm, normal pork was characterized by diameter of muscle of 45.5 µm, while DFD pork ‑ 48.3 µm. Protein composition of Sus scrofa muscle tissues were also investigated by one-dimensional and two-dimensional electrophoresis. 6 protein fractions were identified by mass spectrometry and confirmed as potential biomarkers of pork quality defects in meat and processes meat product. It also has been shown that PSE pork contains 8 characteristic peptides, NOR - 14, DFD - 18. Cathepsin D, calpain 3 and myoglobin content were measured in pork of different categories. The highest content of cathepsin D, calpain 3 and myoglobin was noticed in PSE pork and averaged 82.16 ±3.30 ng.mL-1; 1.280 ±0.082 ng.mL-1; 3.973 ±0.506 ng.mL-1, respectively. Since the study was carried out on samples of meat 24 hours after slaughter, this work had the prospect to further study of meat with different defects of quality during long-term autolysis.

    Edge-effects greatly extend the area of tropical forests degraded through human activities. At Pasoh, Peninsular Malaysia, it has been suggested that soil disturbance by highly abundant wild pigs (Sus scrofa), which feed in adjacent Oil Palm plantations, may have mediated the invasion of Clidemia hirta (Melastomataceae) into the diverse tropical lowland rain forest. To investigate this hypothesis, we established three 1 km transects from the forest/Oil Palm plantation boundary into the forest...

    Full Text Available Thirty pairs of kidneys of wild boar (Sus scrofa were studied from adult males, with permission from the Brazilian Institute of the Environment (Process nº 02001.003237/05, aiming to characterize the vasculature and anatomic surgical segmentation. The arteries of these kidneys were injected with red pigment and subsequently submitted to acid corrosion in order to identify the renal arterial vascular pattern, particularly its divisions and distribution. The results reveal the sectorial branches of the renal arteries, two in number (cranial and caudal; the sectorial arteries provide the segmentary branches to the dorsal and ventral portions of the kidney; in the right kidney, the segmentary branches are 2-6 in the cranial sector and 3-7 in the caudal sector. In the right kidney, the segmentary branches are 3-7 and 2-7 in the same respective sectors; the vascular arterial symmetry (25% between the right and left kidney in the animals is evident. There are 3 arterial anatomic surgical segments on both kidneys. On the basis of the distribution of the sectorial and segmentary arteries, it is possible to accomplish setorectomy and segmentectomy on the kidneys of the wild boar, with functional aspects such as species preservation and animal experimental modeling.

    Bovine tuberculosis is a chronic disease of cattle ( Bos taurus ) caused by the bacterium Mycobacterium bovis . Efforts have been made in the US to eradicate the disease in cattle, but spillover into wildlife and subsequent spillback have impeded progress in some states. In particular, infection in white-tailed deer ( Odocoileus virginianus ) has been followed by infection in cattle in some Midwestern states. Infection has also been documented in feral swine ( Sus scrofa ) on the Hawaiian island of Molokai and in various European countries, but no large-scale survey of antibody exposure to the bacteria has been conducted in feral swine in the US. We tested 488 sera from feral swine collected near previously documented outbreaks of bovine tuberculosis in cattle and captive cervids, in addition to 2,237 feral swine sera collected across the US from 1 October 2013 to 30 September 2014. While all but one of the samples were antibody negative, the results are important for establishing baseline negative data since feral swine are capable reservoirs and could be implicated in future outbreaks of the disease.

    Full Text Available Antimicrobial resistance of bacteria is a worldwide problem affecting wild life by living with resistant bacteria in the environment. This study presents a discussion of outside factors environment on microflora of feral pigs (Sus scrofa from Brazilian Pantanal. Animals had samples collected from six different body sites coming from two separated geographic areas, Nhecolandia and Rio Negro regions. With routine biochemical tests and commercial kits 516 bacteria were identified, with 240 Gram-positive, predominantly staphylococci (36 and enterococci (186 strains. Among Gram-negative (GN bacteria the predominant specimens of Enterobacteriaceae (247 mainly represented by Serratia spp. (105, Escherichia coli (50, and Enterobacter spp. (40 and specimens not identified (7. Antimicrobial susceptibility was tested against 17 drugs by agar diffusion method. Staphylococci were negative to production of enterotoxins and TSST-1, with all strains sensitive towards four drugs and highest resistance toward ampicillin (17%. Enterococci presented the highest sensitivity against vancomycin (98%, ampicillin (94% and tetracycline (90%, and highest resistance pattern toward oxacillin (99%, clindamycin (83%, and cotrimoxazole (54%. In GN the highest resistance was observed with Serratia marcescens against CFL (98%, AMC (66% and AMP (60% and all drugs was most effective against E. coli SUT, TET (100%, AMP, TOB (98%, GEN, CLO (95%, CFO, CIP (93%. The results show a new profile of oxacillin-resistant enterococci from Brazilian feral pigs and suggest a limited residue and spreading of antimicrobials in the environment, possibly because of low anthropogenic impact reflected by the drug susceptibility profile of bacteria isolated.

    Full Text Available The objective of this investigation was to estimate the occurrence of infections by the three zoonotic bacteria Anaplasma phagocytophilum (A. phagocytophilum, Borrelia burgdorferi sensu lato (B. burgdorferi s.l. and Coxiella burnetii in wild boars (Sus scrofa in Central Italy. The spleen samples from 100 hunted wild boars were submitted to DNA extraction and PCR assays were carried out to detect the three agents. One (1% animal was positive for A. phagocytophilum, and three (3% for B. burgdorferi s.l. No positive reactions were observed for Coxiella burnetii. Wild boars did not seem to play an important role in the epidemiology of the three investigated agents. However, the detection of A. phagocytophilum and B. burgdorferi s.l. in the spleen of the tested animals showed that wild boars can harbor these pathogens, thus ticked that feeding on infected wild boars are likely to become infected, too, which represents a source of infection for other animals and humans. This is the first detection of A. phagocytophilum in wild boars in Italy.

    :  Feral swine ( Sus scrofa) are a pathogen reservoir for pseudorabies virus (PrV). The virus can be fatal to wildlife and contributes to economic losses in the swine industry worldwide. National surveillance efforts in the US use serology to detect PrV-specific antibodies in feral swine populations, but PrV exposure is not a direct indicator of pathogen transmission among conspecifics or to non-suid wildlife species. We measured antibody production and the presence of PrV DNA in four tissue types from feral swine populations of Florida, US. We sampled blood, nasal, oral, and genital swabs from 551 individuals at 39 sites during 2014-16. Of the animals tested for antibody production, 224 of 436 (51%) feral swine were antibody positive while 38 of 549 feral swine (7%) tested for viral shedding were quantitative polymerase chain reaction (qPCR)-positive for PrV. The detection of PrV DNA across all the collected sample types (blood, nasal, oral, and genital [vaginal] swabs) suggested viral shedding via direct (oronasal or venereal), and potentially indirect (through carcass consumption), routes of transmission among infected and susceptible animals. Fourteen of 212 seronegative feral swine were qPCR-positive, indicating 7% false negatives in the serologic assay. Our findings suggest that serology may underestimate the actual infection risk posed by feral swine to other species and that feral swine populations in Florida are capable of shedding the virus through multiple routes.

    Corynebacterium pseudotuberculosis is the etiologic agent of caseous lymphadenitis, a common disease in small ruminant populations throughout the world and responsible for a significant economic impact for producers. To our knowledge, this is the first characterization of C. pseudotuberculosis from caseous lymphadenitis lesions in Black Alentejano pig (Sus scrofa domesticus). In this study, phenotypic and genotypic identification methods allocated the swine isolates in C. pseudotuberculosis biovar ovis. The vast majority of the isolates were able to produce phospholipase D and were susceptible to most of the antimicrobial compounds tested. Macrorestriction patterns obtained by Pulsed Field Gel Electrophoresis (PFGE) grouped the C. pseudotuberculosis in two clusters with a high similarity index, which reveals their clonal relatedness. Furthermore, swine isolates were compared with C. pseudotuberculosis from caprines and PFGE patterns also showed high similarity, suggesting the prevalence of dominant clones and a potential cross-dissemination between these two animal hosts. This work represents the first report of Corynebacterium pseudotuberculosis from caseous lymphadenitis lesions in Black Alentejano pig and alerts for the importance of the establishment of suitable control and sanitary management practices to control the infection and avoid further dissemination of this important pathogen to other animal hosts.

    Full Text Available Our study analyzed selected biometric characteristics from 117 wild boars (Sus scrofa ferus harvested during 2008 – 2014 in the Frasin and Marginea Forest hunting ground districts of Suceava County. Hunted boars were measured individually for head-body length (cm, height at withers (cm, length of metatarsus (cm, ear length (cm, tail length (cm and body weight (kg in accordance with their age-class and gender. These characteristics give information on the growth and development of wild boars and on the quality of their habitat. It was found that the average carcass weight was: piglets – 28.4 kg, yearling – 78.1 kg, subadults – 102.9 kg. The results show a faster body growth in females during their first year, while males make up for the weight difference in their 2nd and 3rd year. Statistical differences shown that males differentiate significantly to females by weight, body length, height at withers and length of metatarsus (P < 0.05 starting with their second year of life. The results regarding growth dynamic go along with the changes in boar’s social life, when the males are forced to leave and form smaller groups.

    Tuberculosis, a chronic progressive disease, has been reported in bovine, swine, and primate species. Here, we report the first case of Mycobacterium tuberculosis infection in a Korean wild boar ( Sus scrofa coreanus). The owners this domesticated boar brought it to the Gyeongbuk Veterinary Service Laboratory in Korea after it was found dead and severely emaciated. Demarcated yellowish white nodules were found around the larynx and retropharyngeal lymph node during necropsy. The lungs had diffuse fibrinous pleuritis, severe congestion, and scattered nodules. More nodules were found in the spleen. Tuberculosis is characterized by massive macrophage infiltration and central caseous necrosis; both characteristics were found in the lungs. Histopathologic examination revealed that the alveolar lumen had marked fibrosis and exudates. Examination of the fluid revealed extensive macrophage permeation. To confirm a Mycobacterium infection, PCR was performed using two primer sets specific to the rpoB gene of Mycobacterium; Mycobacterium was detected in the lungs and spleen. To identify the species of Mycobacterium, immunohistochemical evaluation was performed using antibodies against Mycobacterium tuberculosis and Mycobacterium bovis . The results revealed immunoreactivity against M. tuberculosis but not against M. bovis . The consumption of undercooked or raw meat from game animals may expose humans and other animals to sylvatic infection. Consequently, Koreans who ingest wild boar may be at risk of a tuberculosis infection. To reduce the risk of foodborne infection and maintain public health, continuous monitoring and control strategies are required.

    A novel rhabdovirus was isolated from the serum of a healthy Japanese wild boar (Sus scrofa leucomystax) and identified using the rapid determination system for viral nucleic acid sequences (RDV), next-generation sequencing, and electron microscopy. The virus was tentatively named wild boar rhabdovirus 1 (WBRV1). Phylogenetic analysis of the entire genome sequence indicated that WBRV1 is closely related to Tupaia rhabdovirus (TRV), which was isolated from cultured cells of hepatocellular carcinoma tissue of tree shrew. TRV has not been assigned to any genus of Rhabdoviridae till date. Analysis of the L gene indicated that WBRV1 belongs to the genus Vesiculovirus. These observations suggest that both TRV and WBRV1 belong to a new genus of Rhabdoviridae. Next-generation genome sequencing of WBRV1 revealed 5 open reading frames of 1329, 765, 627, 1629, and 6336 bases in length. The WBRV1 gene sequences are similar to those of other rhabdoviruses. Epizootiological analysis of a population of wild boars in Wakayama prefecture in Japan indicated that 6.5% were positive for the WBRV1 gene and 52% were positive for WBRV1-neutralizing antibodies. Furthermore, such viral neutralizing antibodies were found in domestic pigs in another prefecture. WBRV1 was inoculated intranasally and intraperitoneally into SCID and BALB/c mice and viral RNA was detected in SCID mice, suggesting that WBRV1 can replicate in immunocompromised mice. These results indicate this novel virus is endemic in wild animals and livestock in Japan. Copyright © 2015 Elsevier B.V. All rights reserved.

    Over the last 20 years, oral vaccination implementing a live attenuated vaccine has been experimented in Europe in order to control classical swine fever (CSF) in Wild Boar (Sus scrofa sp.). This has generally led to an enhanced seroprevalence and a decreased viroprevalence at the scale of the whole vaccinated populations, but no quantitative analysis has demonstrated the protective effect of preventive vaccination or intensive baiting. In the present paper we conducted a retrospective analysis at the scale of the municipality, taking into account the local dynamics and possible covariates of infection to test the effect of preventive vaccination and of the baiting effort. To be efficient, vaccination was expected to increase seroprevalence above the level considered as suitable for preventing disease invasion (40-60%) independently of infection, to protect free areas from disease invasion or contribute to control subsequent disease intensity and duration. We also hypothesized that a better baiting effort would be correlated with an improvement of immunisation and disease control. In uninfected municipalities, seroprevalence increased up to 40% after 1 year, i.e., three vaccination campaigns. We observed a significant protective effect of preventive vaccination, especially within municipalities that had been vaccinated at least 1 year before disease emergence and where virus detection did not last more than one quarter. On the other hand, we did not detect a significant effect of the baiting effort on local seroprevalence or disease dynamics, suggesting that the baiting system could be improved. We discuss these results regarding the improvement of management measures and further research perspective. Copyright 2009 Elsevier B.V. All rights reserved.

  14. Three-Dimensional Force Measurements During Rapid Palatal Expansion in Sus scrofa

    Full Text Available Rapid palatal expansion is an orthodontic procedure widely used to correct the maxillary arch. However, its outcome is significantly influenced by factors that show a high degree of variability amongst patients. The traditional treatment methodology is based on an intuitive and heuristic treatment approach because the forces applied in the three dimensions are indeterminate. To enable optimal and individualized treatment, it is essential to measure the three-dimensional (3D forces and displacements created by the expander. This paper proposes a method for performing these 3D measurements using a single embedded strain sensor, combining experimental measurements of strain in the palatal expander with 3D finite element analysis (FEA. The method is demonstrated using the maxillary jaw from a freshly euthanized pig (Sus scrofa and a hyrax-design rapid palatal expander (RPE appliance with integrated strain gage. The strain gage measurements are recorded using a computer interface, following which the expansion forces and extent of expansion are estimated by FEA. A total activation of 2.0 mm results in peak total force of about 100 N—almost entirely along the direction of expansion. The results also indicate that more than 85% of the input activation is immediately transferred to the palate and/or teeth. These studies demonstrate a method for assessing and individualizing expansion magnitudes and forces during orthopedic expansion of the maxilla. This provides the basis for further development of smart orthodontic appliances that provide real-time readouts of forces and movements, which will allow personalized, optimal treatment.

    Full Text Available Introduction: The literature is not clear in the ultra-structural manifestations of the vocal wrinkles after neural wound. Objective: To verify the alterations that occur in a vocal fold mechanically denervated. Method: In this prospective study, it were utilized 15 hogs of commercial race (Sus scrofa domesticates, with age of 4 to 12 weeks. The animals were distributed in three groups, chosen at random. Everybody was submitted to the denervation of the right vocal fold, with surgical removal of a segment with three centimeters of the recurring right laryngeal nerve. After 45, 90 and 180 days of the operations, it was proceeded the biopsy of the vocal muscles, it was prosecuted the samples for transmission electron microscopy and, for the ultra-structural study, utilized the transmission electron microscopy Philips, model EM208S. Results: The biopsied groups with 45 and 90 days after operation of mechanical denervation, presented disorganization miofibrilar, only vestigial lines Z in many samples, as well like altered mithochondrions presenting limited sizes, and matrix mithocondrial rarefied with rare mithocondrial cristae present. The biopsied group with 180 days after operation of denervation, presented regular sarcomeres, mithocondrions with sizes and regular number with correct positioning between the sarcomerical units. Conclusion: The finds in the ultra-structure of the vocal muscles suggest to re enervation of the muscle being that the muscular mithochondrions were the most sensible structures to the denervated condition, successions by the cytoarchiteture of the miofibrilas; the finds in the ultra-structure of the vocal muscles suggests to reinervation of the muscle in the period of approximately six months.

    According to the coping styles hypothesis, an individual demonstrates an integrated behavioural and physiological response to environmental challenge that is consistent over time and across situations. Individual consistency in behavioural responses to challenge has been documented across the animal kingdom. Comparatively few studies, however, have examined inter-individual variation in the physiological response, namely glucocorticoid and catecholamine levels, the stress hormones secreted by the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system, respectively. Variation in coping styles between individuals may be explained in part by differences in social rank and sex. Using 20 Yucatan minipigs (Sus scrofa) we: (1) investigated the existence of consistent inter-individual variation in exploratory behaviour and the hormonal stress response, and tested for correlations as predicted by the coping styles hypothesis; and (2) evaluated whether inter-individual behavioural and hormonal variation is related to social rank and sex. Salivary stress biomarkers (cortisol, alpha-amylase, chromogranin A) were assessed in the presence and absence of a stressor consisting of social isolation in a crate for 10 min. Principal components analysis on a set of behavioural variables revealed two traits, which we labelled exploratory tendency and neophobia. Neither exploratory tendency nor neophobia predicted the physiological stress response. Subordinate pigs exhibited higher catecholamine levels compared to dominant conspecifics. We observed sex differences in the repeatability of salivary stress markers and reactivity of the stress systems. The results do not provide support for the existence of behavioural-physiological coping styles in pigs. Sex is an important determinant of the physiological stress response and warrants consideration in research addressing behavioural and hormonal variation. Copyright © 2015 Elsevier Inc.

    Full Text Available Heavy metals are toxic elements naturally present in the environment which can be bioconcentrated by plants and animals and incorporated into food cycles. Thus the use of wildlife species as monitors is a useful tool to assess environmental pollution. Because of its ethological characteristics, wild boar is highly probable to be exposed to pollution, mainly by heavy metals. These pollutants, when present at high enough concentrations, can induce histological lesion in various tissues. The purpose of the present work was to investigate the levels of five metals (cadmium, copper, iron, lead and zinc in wild boar, Sus scrofa, originating from an Apennine area of Emilia Romagna, Northern Italy, and to evaluate any possible correlation with histological lesions eventually observed. Samples of several organs (liver, heart, kidney, diaphragm, abductor muscle, masseter, eye, testis, brain, lung and spleen were collected from hunted animals during winter 2001. Levels of metals were determined on freeze dried tissues employing microwave wet digestion. Toxicological analysis were performed by atomic absorption spectrophotometry and data expressed on a dry weight basis. Histopatological analyses were performed on fixed samples of the same tissue. Highest mean values were found in kidney for cadmium and copper (7 ± 1 ppm and 30 ± 2.6 ppm respectively and in liver for copper (21.16 ± 3.28 ppm, lead (2139 ± 680.6 ppb, iron (415.92 ± 24.41 ppm and zinc (94.76 ± 6.11 ppm. In all other tissues, mean concentrations of each metal were at low levels, and were comparable one another. A statistical difference was found for iron (p<0.05, copper (p<0.05 and cadmium (p<0.01 in kidney, in testis (p<0.01 for zinc and in liver for copper (p<0.05 and cadmium (p<0.01 as function of age cohorts. When sex was considered, a statistical difference was found for iron in eye, for copper in heart and for cadmium in heart and kidney. Histopatological analysis allowed

    Since 1995 the population of wild ungulates increased significantly in the "Parco provinciale dei Monti Livornesi" (Livorno, Tuscany, Central Italy). We studied the intestinal macroparasites of two hosts, the wild boar (Sus scrofa) and the mouflon (Ovis gmelini musimon). In the case of wild boars we found a dominant parasite species, Globocephalus urosubulatus. For this parasite the frequency distribution of the number of parasites per host agrees with a negative binomial distribution. There is not a significant correlation between the age of the animals and the parasitosis. Furthermore the mean parasite burden of male and female wild boars does not differ significantly. In the case of mouflons we found a dominant parasite species Nematodirus filicollis with Trichuris ovis as codominant species.

    Full Text Available Abstract The following study contains and analyses data about the wild boar (Sus scrofa hunted in the Como and Varese provinces from October 1993 to January 1994. These populations have been formed from individuals which have been illegally introduced continuously since 1978 in the Varese province and since the mid 80s in the Como province. Some of them have also come from the neighbouring Switzerland. Biometric analyses were carried out on 189 specimens, and were divided into age and sex classes. We considered 8 measurements for some external morphological characteristics and 28 for the skull structure. For each specimen the age class was evaluated by tooth growth analysis. The possible presence of fetuses in every female was also checked. The data collected by the Veterinary Service (U.S.S.L. enabled us to identify the main diseases of the studied populations. Frequent cases of tuberculosis were observed.

    Full Text Available Aim: Wild boars, Sus scrofa, are potential reservoirs of many zoonotic diseases, and there are a possibility of transmission of the zoonotic diseases from these animals to humans and also domestic animals. This study aimed to evaluate the protozoan contamination of wild boars in the Persian Gulf’s coastal area (Bushehr Province, southwestern Iran. Materials and Methods: A total of 25 crossbred boars were collected during a course of vertebrate pest control in Bushehr province, in 2013. Samples were collected from the gastrointestinal tracts of each boar in 5% formalin, Bouin’s solution, sodium acetate-acetic acid-formalin, and polyvinyl alcohol fixatives. Fixed stool smears examined by trichrome and Ziehl–Neelsen staining. Results: Each of the 25 wild boars was infected with at least one of the intestinal protozoans. The rate of contamination with intestinal protozoan was 64% for Balantidium coli, 76% for Iodamoeba sp., 52% for Entamoeba polecki, 44% for Blastocystis sp. and 8% for Chilomastix sp. No intestinal coccidian was detected in studied boars when the stool samples were evaluated by Ziehl–Neelsen staining method. Conclusion: Findings of this study demonstrated that wild boars in the Persian Gulf coastal area are contaminated by many protozoans, including zoonotic protozoan, which poses a potential risk to locals as well as the domestic animals of the area.

    Edge-effects greatly extend the area of tropical forests degraded through human activities. At Pasoh, Peninsular Malaysia, it has been suggested that soil disturbance by highly abundant wild pigs (Sus scrofa), which feed in adjacent Oil Palm plantations, may have mediated the invasion of Clidemia hirta (Melastomataceae) into the diverse tropical lowland rain forest. To investigate this hypothesis, we established three 1 km transects from the forest/Oil Palm plantation boundary into the forest interior. We recorded the distribution of soil disturbance by wild pigs, C. hirta abundance, and environmental variables. These data were analyzed using a hierarchical Bayesian model that incorporated spatial auto-correlation in the environmental variables. As predicted, soil disturbance by wild pigs declined with distance from forest edge and C. hirta abundance was correlated with the level of soil disturbance. Importantly there was no effect of distance on C. hirta abundance, after controlling for the effect of soil disturbance. Clidemia hirta abundance was also correlated with the presence of canopy openings, but there was no significant association between the occurrence of canopy openings and distance from the edge. Increased levels of soil disturbance and C. hirta abundance were still detectable approximately 1 km from the edge, demonstrating the potential for exceptionally large-scale animal mediated edge effects.

    In South America, wild populations of peccaries coexist with domestic and feral pigs, with poorly understood consequences. We captured 58 collared peccaries ( Pecari tajacu) and 15 feral pigs ( Sus scrofa) in locations of Colombia where coexistence of these species is known. Blood samples were tested for antibodies against four viral agents, classical swine fever virus (CSFV), Aujeszky's disease virus (ADV), porcine circovirus (PCV-2), and vesicular stomatitis virus (New Jersey and Indiana subtypes) and two bacterial agents, Brucella spp. and six serovars of Leptospira interrogans. The prevalence of CSFV was 5% (3/58) in collared peccaries and 7% (1/15) in feral pigs. The prevalence of PCV-2 was 7% (1/15) in collared peccaries and 67% (2/3) in feral pigs. Vesicular stomatitis prevalence was 33% (8/24) in collared peccaries and 67% (4/6) in feral pigs. Leptospira prevalence was 78% (39/50) in collared peccary and 100% (8/8) in feral pigs; bratislava, grippotyphosa, icterohaemorrhagiae, and pomona were the most frequent serovars. Also, the only white-lipped peccary ( Tayassu pecari) sampled was positive for L. interrogans serovar bratislava and for vesicular stomatitis virus, New Jersey strain. No samples were positive for ADV or Brucella. The seroprevalence of antibodies against L. interrogans was similar to that observed in other studies. Icterohaemorrhagiae appears to be a common serovar among in situ and ex situ peccary populations. Positive antibodies against PVC-2 represent a novel report of exposure to this pathogen in Colombian peccaries. Our results indicate the possible transmission of various pathogens, important for pig farms, in the studied pig and peccaries.

    Full Text Available BACKGROUND: To obtain robust epidemiological information regarding tuberculosis (TB in wildlife species, appropriate diagnostic methods need to be used. Wild boar (Sus scrofa recently emerged as a major maintenance host for TB in some European countries. Nevertheless, no data is available to evaluate TB post-mortem diagnostic methods in hunter-harvested wild boar. METHODOLOGY/PRINCIPAL FINDINGS: Six different diagnostic methods for TB were evaluated in parallel in 167 hunter-harvested wild boar. Compared to bacteriological culture, estimates of sensitivity of histopathology was 77.8%, gross pathology 72.2%, PCR for the MPB70 gene 66.7%, detection of acid-fast bacilli (AFB in tissue contact smears 55.6% and in histopathology slides 16.7% (estimated specificity was 96.7%, 100%, 100%, 94.4% and 100%, respectively. Combining gross pathology with stained smears in parallel increased estimated sensitivity to 94.4% (94.4% specificity. Four probable bacteriological culture false-negative animals were identified by Discriminant Function Analysis. Recalculating the parameters considering these animals as infected generated estimated values for sensitivity of bacteriology and histopathology of 81.8%, gross pathology 72.7%, PCR for the MPB70 gene 63.6%, detection of AFB in tissue contact smears 54.5% and in histopathology slides 13.6% (estimated specificity was 100% for gross pathology, PCR, bacteriology and detection of AFB in histopathology slides, 96.7% for histopathology and 94.4% for stained smears. CONCLUSIONS/SIGNIFICANCE: These results show that surveys for TB in wild boar based exclusively on gross pathology considerably underestimate prevalence, while combination of tests in parallel much improves sensitivity and negative predictive values. This finding should thus be considered when planning future surveys and game meat inspection schemes. Although bacteriological culture is the reference test for TB diagnosis, it can generate false

    Mercury (Hg) is likely bound to large biomolecules (e.g. proteins) in living organisms, and in order to assess Hg metabolic pathways and possible toxicological effects, it is essential to study these Hg containing biomolecules. However, the exact nature of most metal binding biomolecules is unknown. Such studies are still in their infancy and information on this topic is scarce because the analysis is challenging, mainly due to their lability upon digestion or extraction from the tissue. New analytical methods that allow complex Hg-biomolecules to be analysed intact are needed and only few very recent studies deal with this approach. Therefore, as an initial step towards the characterization of Hg containing biomolecules, an analytical procedure has been optimised using size-exclusion chromatography (SEC) with inductively coupled plasma mass spectrometry (ICP-MS) detection. We applied this technique to elucidate the distribution and elution profile of Hg and Se, and some physiological important elements such as Fe, Ni, Zn and Cu, to assess metal binding profiles in liver and kidney samples of red deer (Cervus elaphus) and wild boar (Sus scrofa) who roam freely within the largest Hg mining district on Earth, Almadén in Spain. Elemental fractionation profiles of the extracts from different tissues were obtained using two different SEC columns (BioSep-SEC-S2000 GL 300-1kDa and Superdex 75 10/300 GL 70-3kDa). Similar profiles of Hg were observed in red deer and wild boar; however, significant differences were evident for liver and kidney. Moreover, the profiles of Se showed a single peak at high-medium molecular weight in all investigated tissues, while co-elution of Hg with Fe, Ni, Zn and Cu was observed.

    Colino–Rabanal, V. J.

    2012-01-01

    Full Text Available In recent decades, wild boar populations have increased both in number and distribution. This rise is partly related to the increase in cropland devoted to maize (Zea mays cultivation, as wild boar find food and refuge in these areas. This population expansion has led to an increase in the number of wild boar vehicle collisions (WBVCs. The goal of the present study was to evaluate a set of spatio–temporal factors that influence WBVCs related to maize crops on the Northern Spanish Plateau (the region of Castile and Leon. We compared the maize pattern with the factors related to total WBVC numbers. We observed that whereas the total occurrence of WBVCs usually increased with forest cover and speed and traffic volumes, maize areas were one of the main explanatory variables in plateau models. To avoid collisions in these areas in future, a number of mitigation measures are outlined.

    In many parts of the developing world, pigs are kept under low-input systems where they roam freely to scavenge food. These systems allow poor farmers the opportunity to enter into livestock keeping without large capital investments. This, combined with a growing demand for pork, especially in urban areas, has led to an increase in the number of small-holder farmers keeping free range pigs as a commercial enterprise. Despite the benefits which pig production can bring to a household, keeping pigs under a free range system increases the risk of the pig acquiring diseases, either production-limiting or zoonotic in nature. This study used Global Positioning System (GPS) technology to track free range domestic pigs in rural western Kenya, in order to understand their movement patterns and interactions with elements of the peri-domestic environment. We found that these pigs travel an average of 4,340 m in a 12 hr period and had a mean home range of 10,343 m(2) (range 2,937-32,759 m(2)) within which the core utilisation distribution was found to be 964 m(2) (range 246-3,289 m(2)) with pigs spending on average 47% of their time outside their homestead of origin. These are the first data available on the home range of domestic pigs kept under a free range system: the data show that pigs in these systems spend much of their time scavenging outside their homesteads, suggesting that these pigs may be exposed to infectious agents over a wide area. Control policies for diseases such as Taenia solium, Trypanosomiasis, Trichinellosis, Toxoplasmosis or African Swine Fever therefore require a community-wide focus and pig farmers require education on the inherent risks of keeping pigs under a free range system. The work presented here will enable future research to incorporate movement data into studies of disease transmission, for example for the understanding of transmission of African Swine Fever between individuals, or in relation to the life-cycle of parasites including Taenia

  13. Utilization of sugarcane habitat by feral pig (Sus scrofa in northern tropical Queensland: evidence from the stable isotope composition of hair.

    Christopher M Wurster

    Full Text Available Feral pigs (Sus scrofa are an invasive species that disrupt ecosystem functioning throughout their introduced range. In tropical environments, feral pigs are associated with predation and displacement of endangered species, modification of habitat, and act as a vector for the spread of exotic vegetation and disease. Across many parts of their introduced range, the diet of feral pigs is poorly known. Although the remote location and difficult terrain of far north Queensland makes observing feral pig behavior difficult, feral pigs are perceived to seek refuge in World Heritage tropical rainforests and seasonally 'crop raid' into lowland sugarcane crops. Thus, identifying how feral pigs are using different components of the landscape is important to the design of management strategies. We used the stable isotope composition of captured feral pigs to determine the extent of rainforest and sugarcane habitat usage. Recently grown hair (basal hair from feral pigs captured in remote rainforest indicated pigs met their dietary needs solely within this habitat. Stable carbon and nitrogen isotope values of basal hair from feral pigs captured near sugarcane plantations were more variable, with some individuals estimated to consume over 85% of their diet within a sugarcane habitat, while a few consumed as much as 90% of their diet from adjacent forested environments. We estimated whether feral pigs switch habitats by sequentially sampling δ(13C and δ(15N values of long tail hair from a subset of seven captured animals, and demonstrate that four of these individuals moved between habitats. Our results indicate that feral pigs utilize both sugarcane and forest habitats, and can switch between these resources.

    Full Text Available The aim of the study was to analyse the fatty acid profile of wild boar (Sus scrofa meat. The samples were obtained from the mountain Tríbeč (southwest part of the Slovak Republic. A total of 36 samples in 3 age categories of meat were analysed. The effect of age on the intramuscular (IMF fat content was analysed. The highest (P < 0.05 IMF content was found in the samples from the youngest animals (18.07%, the lowest (P < 0.05 in the sub-adult animals. Significant (P < 0.05 differences were found in palmitic acid (C16:0. Significant decrease of heptadecanoic acid (C17:0 as an effect of age was analysed in the samples. Of the important fatty acids, the most abundant in all age categories of wild boar were oleic (C18:1 cis 9, palmitic (C16:0, and linolelaidic acid (C18:2 cis n6. Differences in the content of mentioned acids were significant (P < 0.05. In α-linolenic and γ-linoleic acids, non-significant (P > 0.05 differences were detected. Significant differences (P < 0.05 between age categories were found in cis-11-eicosenoic (C20:1 n9 and cis-11,14-eicosadienoic acids (C20:2 n6. Significant differences (P < 0.05 were found in PUFA (polyunsaturated fatty acids, MUFA (monounsaturated fatty acids, and SFA (saturated fatty acids concentrations. The highest PUFA content was typical for the samples from the oldest animals, MUFA from the sub-adults, and SFA from the youngest wild boar. More significant results were observed in the normalized data with the factor component scores. The wild boar fatty acid profile is significantly affected by age.

    Full Text Available Wild boar is a host of a number of arthropod-vectored diseases and its numbers are on the rise in mainland Europe. The species potentially impacts ecosystems, humans and farming practices and so its distribution is of interest to policy makers in a number of fields beyond that of the primarily epidemiological goal of this study. Three statistical model outputs describing the distribution and abundance of the species Sus scrofa (Wild boar are included in this data package. The extent of this dataset covers continental Europe. These data were presented as a poster [1] at the conference Genes, Ecosystems and Risk of Infection (GERI 2015. The first of the three models provide a European map presenting the probability of presence of Sus scrofa, which can be used to describe the likely geographical distribution of the species. The second and third models provide indices to help describe the likely abundance across the continent. The two indices include “the proportion of suitable habitat where presence is estimated” and a simple classification of boar abundance across Europe using quantiles of existing abundance data and proxies.

    Full Text Available Abstract Wild boar (Sus scrofa spreading and crop damage in an area of western Prealps We analysed the agricultural damage reports from 1986 to 1996 to evidence the wild boar distribution in Biella province and the pattern of land occupancy. These reports were yearly divided and mapped for the single municipalities to obtain a picture of the range variations in the time. From the same reports we calculated three indexes of the importance of the Wild boar damages: the damaged surface for each municipality, its percentage value on the surface of each municipality and the occurrence of damages for each municipality. During the study period, we observed a dramatic increase of the number of municipalities affected by wild boar damages and of the species range. The yearly damaged surface grew over 25 times too. The Discriminant Function Analysis carried out between damaged and undamaged municipalities correctly classified 78,1% of total cases by three variables: mixed woods, pastures and dry crops, the second one being the most important. The Multiple Regression Analysis of the damages occurrence vs. habitat variables explained 77,3% of independent variable variance by five variables, which entered the model. The trend analysis, carried out by the seasonal regression, using the surface and the occurrence of damages, evidenced a marked seasonality of the damages and a stability trend, after an initial positive trend. Riassunto Per evidenziare la distribuzione del Cinghiale in provincia di Biella e le modalità d'occupazione del territorio nel corso degli anni, sono state utilizzate le denunce dei danni pervenute all Amministrazione provinciale dal 1986 al 1996.

    Full Text Available Mycobacterium celatum, a slowly growing potentially pathogenic mycobacterium first described in humans, is regarded as an uncommon cause of human infection, though capable of inducing invasive disease in immunocompromised hosts. According to some reports, a serious disease due to M. celatum may also occur in individuals with no apparent immunodeficiency. In animals, an M. celatum-related disease has been described in three cases only: twice in a domestic ferret (Mustela putorius furo and once in a white-tailed trogon (Trogon viridis. In this paper, we report the first detection of M. celatum in a domestic pig (Sus scrofa domestica and roe deer (Capreolus capreolus. A nation-wide overview of human M. celatum infections recorded in Slovenia between 2000 and 2010 is also given. Pulmonary disease due to M. celatum was recognized in one patient with a history of a preexisting lung disease.

    Full Text Available Abstract Background Lymphocyte function-associated antigen-1 (LFA-1, CD11a/CD18, alphaLbeta2, the most abundant and widely expressed beta2-integrin, is required for many cellular adhesive interactions during the immune response. Many studies have shown that LFA-1 is centrally involved in the pathogenesis of several diseases caused by Repeats-in-toxin (RTX -producing bacteria. Results The porcine-LFA-1 CD11a (alpha subunit coding sequence was cloned, sequenced and compared with the available mammalian homologues in this study. Despite some focal differences, it shares all the main characteristics of these latter. Interestingly, as in sheep and humans, an allelic variant with a triplet insertion resulting in an additional Gln-744 was consistently identified, which suggests an allelic polymorphism that might be biologically relevant. Conclusion Together with the pig CD18-encoding cDNA, which has been available for a long time, the sequence data provided here will allow the successful expression of porcine CD11a, thus giving the first opportunity to express the Sus scrofa beta2-integrin LFA-1 in vitro as a tool to examine the specificities of inflammation in the porcine species.

    Bovine tuberculosis (bTB) is a (re-)emerging disease in European countries, including Switzerland. This study assesses the seroprevalence of infection with Mycobacterium bovis and closely related agents in wild boar (Sus scrofa) in Switzerland, because wild boar are potential maintenance hosts of these pathogens. The study employs harmonised laboratory methods to facilitate comparison with the situation in other countries. Eighteen out of 743 blood samples tested seropositive (2.4%, CI: 1.5-3.9%) by ELISA, and the results for 61 animals previously assessed using culture and PCR indicated that this serological test was not 100% specific for M. bovis, cross-reacting with M. microti. Nevertheless, serology appears to be an appropriate test methodology in the harmonisation of wild boar testing throughout Europe. In accordance with previous findings, the low seroprevalence found in wild boar suggests wildlife is an unlikely source of the M. bovis infections recently detected in cattle in Switzerland. This finding contrasts with the epidemiological situation pertaining in southern Spain. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The expansion of feral swine (Sus scrofa) populations into new geographic regions is of concern not only due to increased range but also because they carry diseases and parasites that pose a threat to humans, livestock, and wildlife into new areas. Recently, emerging feral swine populations have been reported in the northeastern US and due to their adaptive nature will likely continue to spread. During 2009-2012, 49 feral swine were removed from three counties in New Hampshire. Of these, serum samples were submitted from 34 for disease surveillance testing. One of the feral swine was antibody-positive for pseudorabies virus (PRV) making it the first documented infection in feral swine in New Hampshire. Infestations of winter tick (Dermacentor albipictus) were also documented on two of the feral swine which had only been reported previously on feral swine in Texas. Feral swine may not only serve as an important host for an economically important commercial swine pathogen like PRV, but they could also increase host diversity for parasites such as the winter tick, a species that can regionally impact moose (Alces alces) survival. These findings warrant further investigation of expanding and established feral swine populations in New Hampshire as pathogen hosts and support continued effort to reduce numbers or regionally eradicate feral swine.

The present study aimed to analyze and compare the dipterofauna that visit or colonize carcasses in the urban and coastal areas of São Paulo, Brazil, during summer and winter seasons. Four swine (Sus scrofa Linné, 1758 carcasses of approximately 12 kg were used. The animals were previously euthanized and then placed in metal cages covered with a flight intercept trap (Shannon, modified. In total, 10,495 flies from 39 families were collected, with 15 species belonging to the Calliphoridae family, 14 species belonging to the Fanniidae family, 43 species belonging to the Muscidae family, and 22 species belonging to the Sarcophagidae family. Flies from these four families visited all carcasses; however, they did not show the highest visitation frequencies in all of the trials. Species variations occurred between the experiments that were performed at different locations and in different seasons. Furthermore, difference in the number of insects attracted to each stage of decomposition was observed. In addition to the four families highlighted above, the families Phoridae, Sepsidae, Otitidae, and Piophilidae were observed in all carcasses.

    Trypsin is one of the most important enzymatic tools in proteomics and biopharmaceutical studies. Here, we describe the complete recombinant expression and purification from a trypsinogen expression vector construct. The Sus scrofa cationic trypsin gene with a propeptide sequence was optimized according to Escherichia coli codon-usage bias and chemically synthesized. The gene was inserted into pET-11c plasmid to yield an expression vector. Using high-density E. coli fed-batch fermentation, trypsinogen was expressed in inclusion bodies at 1.47 g/L. The inclusion body was refolded with a high yield of 36%. The purified trypsinogen was then activated to produce trypsin. To address stability problems, the trypsin thus produced was acetylated. The final product was generated upon gel filtration. The final yield of acetylated trypsin was 182 mg/L from a 5-L fermenter. Our acetylated trypsin product demonstrated higher BAEE activity (30,100 BAEE unit/mg) than a commercial product (9500 BAEE unit/mg, Promega). It also demonstrated resistance to autolysis. This is the first report of production of acetylated recombinant trypsin that is stable and suitable for scale-up. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Introduction and objective. The aims of the study were: 1 to detect antibodies against T[i]oxoplasma gondii[/i] from wild boar meat; 1 establish seroprevalence of toxoplasmosis in the wild boar population; 3 establish risk factors concerned in higher possible seroprevalence; 4 to estimate the usefulness of meat juice for detection of [i]T. gondii[/i] antibodies in wild boar. Material and methods. Diaphragm meat juice samples from 656 wild boar ([i]Sus scrofa[/i] were collected during the hunting seasons between September 2008 – October 2010 from 9 districts of the Czech Republic. The samples were stratified per age category into 2 groups: piglets (n = 279 and yearlings together with adults (n = 377. The in-house ELISA test was used for the detection of antibodies against [i]T. gondii [/i]from the meat juice samples. Results. Antibodies against [i]T. gondii [/i]were detected by in-house ELISA in 260 of 656 wild boars (40% with 26% prevalence in piglets (72/279 and 50% prevalence in yearlings and adults (188/377. The district total seroprevalences ranged between 32% – 59%, with a significantly higher prevalence in the district of Havlíčkův Brod (59%. Statistically significant differences (p-value < 0.05 were found between 2 age categories, and between 9 districts, with a significant variability in the district of Havlíčkův Brod. Seroprevalence correlated positively with farm density, but without any statistical significance. Conclusion. The obtained results indicate that consumption of raw or undercooked meat from wild boars can carry an important risk of toxoplasma infection. Post mortem detection of antibodies in meat juice samples using ELISA is a useful alternative to blood serum examination. In addition, a diaphragm sample has been well-proven as a matrix sample for the contemporaneous diagnostics of trichinellosis and toxoplasmosis.

    Full Text Available Aquatic and semiaquatic mammals have the capacity of breath hold (apnea diving. Northern elephant seals (Mirounga angustirostris have the ability to perform deep and long duration dives; during a routine dive, adults can hold their breath for 25 min. Neotropical river otters (Lontra longicaudis annectens can hold their breath for about 30 sec. Such periods of apnea may result in reduced oxygen concentration (hypoxia and reduced blood supply (ischemia to tissues. Production of adenosine 5’-triphosphate (ATP requires oxygen, and most mammalian species, like the domestic pig (Sus scrofa, are not adapted to tolerate hypoxia and ischemia, conditions that result in ATP degradation. The objective of this study was to explore the differences in purine synthesis and recycling in erythrocytes and plasma of three mammalian species adapted to different environments: aquatic (northern elephant seal (n=11, semiaquatic (neotropical river otter (n=4 and terrestrial (domestic pig (n=11. Enzymatic activity of hypoxanthine-guanine phosphoribosyltransferase (HGPRT was determined by spectrophotometry, and activity of inosine 5’-monophosphate dehydrogenase (IMPDH and the concentration of hypoxanthine (HX, inosine 5’-monophosphate (IMP, adenosine 5’-monophosphate (AMP, adenosine 5’-diphosphate (ADP, ATP, guanosine 5’-diphosphate (GDP, guanosine 5’-triphosphate (GTP, and xanthosine 5’-monophosphate (XMP were determined by high-performance liquid chromatography (HPLC. The activities of HGPRT and IMPDH and the concentration of HX, IMP, AMP, ADP, ATP, GTP and XMP in erythrocytes of domestic pigs were higher than in erythrocytes of northern elephant seals and river otters. These results suggest that under basal conditions (no diving, sleep apnea or exercise, aquatic and semiaquatic mammals have less purine mobilization than their terrestrial counterparts.

    Full Text Available In spring 2012, osteological material was collected at the “Gornja Šuma” site (site no. 47, located in the territory of Novi Sad, and it was dated to the early 9th century. The withers heights of pig - Sus scrofa domestica, domestic cow - Bos taurus and sheep - Ovis aries, as the three most dominant species at this archaeological site, were analysed based on the length of bones and according to various authors [Boessneck 1956; Zalkin 1960; Matolcsi 1970; Teichert 1975]. It was determined that in these three species the withers heights mostly corresponded to the data from the Middle Ages.

    We studied the concentration and distribution of 137 Cs and 90 Sr in the bodies of 188 wild boar (Sus scrofa Linnaeus, 1758) taken near the Chernobyl site. Of these, 111 animals were taken in the Alienation Zone, 41 animals were taken in the Permanent Control Zone and 36 animals were taken in the Periodic Control Zone. The samples included muscle and bone (rib) tissues and samples of heart, liver, lungs, kidneys, spleen, genitals and skin. The weight of the samples was 0.5 kg fresh weigh. The average concentration of 137 Cs in the muscles of the wild boar found in the Alienation Zone was 46 ± 10 kBq/kg, in the Permanent Control Zone – 13 ± 3.0 kBq/kg and in the Periodic Control Zone – 0.6 ± 0.1 kBq/kg. The largest concentration of 137 Cs was detected in the muscle tissue and kidneys taken animals. In some samples of muscle tissue it reached more than 660 kBq/kg. The 137 Cs concentrations were also high in heart and spleen up 64.3 kBq/kg and 67.5 kBq/kg – animals from the Alienation Zone and 10.3–10.6 kBq/kg – animals from the Permanent Control zone. The lowest concentration of 137 Cs was found in the lungs and skin of animals. The analyses of 90 Sr concentration in the organs and tissues of the wild boar showed that 90 Sr was concentrated mainly in the bone tissue. The average level of 90 Sr concentration in bone was 17.6 kBq/kg fresh weight animals from the Alienation Zone and 13.47 kBg/kg – animals from the Permanent Control zone. In muscle tissues and organs contained 90 Sr – 30.0–110.0 Bq/kg in the Alienation Zone and 11.0–30.0 Bq/kg in the Permanent Control zone

    Full Text Available The aim of this data was to analyze morphology and function of the seminiferous tubule in adult wild boars. Testes removed by unilateral castration of five animals were used. The testicular parenchyma was composed by 82.1±2.2% of seminiferous tubule and 17.9±2.2% of intertubular tissue. The tubular diameter was 249.2±33.0 µm and the seminiferous tubule lenght per gram of testis was 19.3±4.9m. The spermatogonial mitoses efficiency coefficient, meiotic index and spermatogenesis efficiency were 10.34, 2.71 and 30.5 respectively. Each Sertoli cell supported about 13 germinatives cells. The hystometric parameters studied were very similar to those related for domestic boars, however, the wild boars intrinsic efficiency of spermatogenesis and Sertoli cells indexes were smaller than in domestic boars.Objetivou-se com esta pesquisa estudar as características morfométricas e funcionais dos túbulos seminíferos de javalis adultos. Utilizaram-se testículos de cinco animais submetidos a orquiectomia unilateral. O parênquima testicular foi composto por 82,1 ± 2,2% de túbulos seminíferos e 17,9 ± 2,2% de tecido intertubular. O diâmetro tubular foi de 249,2 ± 33,0µm e o comprimento dos túbulos seminíferos por grama de testículo foi de 19,3 ± 4,9m. O coeficiente de eficiência das mitoses espermatogônias, o rendimento meiótico e o rendimento geral da espermatogênese foram, respectivamente, 10,34, 2,71 e 30,50. Cada célula de Sértoli suportou cerca de 13 células germinativas. Conclui-se que os parâmetros histométricos estudados nesta pesquisa foram muito semelhantes aos valores relatados para suínos domésticos, entretanto, o rendimento intrínseco da espermatogênese e os índices de células de Sértoli de javalis foram relativamente baixos quando comparados com aqueles animais.

Estos resultados remarcan la importancia del monitoreo de la interfase productiva/silvestre en función de la salud pública, producción animal y conservación de la biodiversidad.

  15. Investigating the role of free-ranging wild boar (Sus scrofa in the re-emergence of enzootic pneumonia in domestic pig herds: a pathological, prevalence and risk-factor study.

    Directory of Open Access Journals (Sweden)

    Mainity Batista Linhares

    Full Text Available Enzootic pneumonia (EP caused by Mycoplasma hyopneumoniae has a significant economic impact on domestic pig production. A control program carried out from 1999 to 2003 successfully reduced disease occurrence in domestic pigs in Switzerland, but recurrent outbreaks suggested a potential role of free-ranging wild boar (Sus scrofa as a source of re-infection. Since little is known on the epidemiology of EP in wild boar populations, our aims were: (1 to estimate the prevalence of M. hyopneumoniae infections in wild boar in Switzerland; (2 to identify risk factors for infection in wild boar; and (3 to assess whether infection in wild boar is associated with the same gross and microscopic lesions typical of EP in domestic pigs. Nasal swabs, bronchial swabs and lung samples were collected from 978 wild boar from five study areas in Switzerland between October 2011 and May 2013. Swabs were analyzed by qualitative real time PCR and a histopathological study was conducted on lung tissues. Risk factor analysis was performed using multivariable logistic regression modeling. Overall prevalence in nasal swabs was 26.2% (95% CI 23.3-29.3% but significant geographical differences were observed. Wild boar density, occurrence of EP outbreaks in domestic pigs and young age were identified as risk factors for infection. There was a significant association between infection and lesions consistent with EP in domestic pigs. We have concluded that M. hyopneumoniae is widespread in the Swiss wild boar population, that the same risk factors for infection of domestic pigs also act as risk factors for infection of wild boar, and that infected wild boar develop lesions similar to those found in domestic pigs. However, based on our data and the outbreak pattern in domestic pigs, we propose that spillover from domestic pigs to wild boar is more likely than transmission from wild boar to pigs.

    Full Text Available O objetivo desse estudo foi descrever o quadro clínico e epidemiológico, os achados patológicos, bacteriológicos e imuno-histoquímicos de um surto de pneumonia em uma granja de Javalis do Distrito Federal, Brasil. Em um período de cinco meses, morreram 90 javalis. Desses, 63 tinham lesões pulmonares. Clinicamente apresentavam atraso no desenvolvimento corporal, diminuição do apetite, letargia, tosse e dificuldade respiratória, principalmente quando movimentados. Constatou-se elevação da temperatura, 40ºC em média. Na auscultação, havia crepitações e estertores pulmonares de intensidade moderada. As alterações macroscópicas nos pulmões analisados eram típicas de broncopneumonia lobular. As lesões caracterizavam-se por consolidação crânio-ventral na maioria dos pulmões. A coloração variava de difusamente vermelho-escuro a um padrão mosaico (lóbulos vermelho-escuros intercalados por lóbulos cinzas ou difusamente acinzentados. Na maioria dos pulmões observou-se exsudato mucopurulento na luz dos brônquios e fluindo do parênquima. Histologicamente, as alterações eram de broncopneumonia purulenta e histiocitária com focos de necrose. Em alguns animais havia também hiperplasia do BALT e, na maioria dos animais, infiltração linfocítica perivascular e peribronquial. Bordetella bronchiseptica e Streptococcus spp. foram as principais bactérias isoladas. A imuno-histoquímica demonstrou a bactéria Mycoplasma hyopneumoniae no epitélio bronquiolar e bronquial e o DNA desta bactéria foi detectado pela PCR. Este é o primeiro relato de broncopneumonia em Javalis associado à infecção por M. hyopneumoniae.The aim of this paper is to describe the clinical, epidemiological, pathological, bacteriological and immunohistochemical aspects of a pneumonia outbreak in a wild pig farm in the Distrito Federal, Brazil. Ninety wild pigs died in a period of five months, and 63 of these had pulmonary lesions. Clinically, the pigs presented reduced growth rate, anorexia, lethargy, cough and dyspnea, especially after they were moved. High body temperature (40ºC in average was verified in some animals. Auscultation revealed moderate pulmonary crepitation and stertors. Pulmonary gross lesions were typical of lobular bronchopneumonia. Lung lesions were characterized by ventral-cranial consolidation in the majority of the cases. The color of affected pulmonary areas varied from diffuse dark red to mosaic pattern (dark red lobule intercalate by grayish lobule or diffusely grayish. The majority of the lungs had mucopurulent exsudate in the bronchial lumen that also drained from the parenchyma cut surface. Upon microscopy, the changes were characterized by purulent and histiocytic bronchopneumonia with necrotic foci. In some animals, there was BALT hyperplasia associated with perivascular and peribronchial plasma cells and lymphocytes infiltration in most of these cases. Bordetella bronchiseptica and Streptococcus spp. were the most frequently isolated bacteria. Immunohistochemistry evaluation demonstrated Mycoplasma hyopneumoniae on the luminal surface of bronchial and bronchiolar epithelial cells, and the DNA of bacteria was detected by PCR. This is the first report of bronchopneumonia in wild boars associated with M. hyopneumoniae infection.

O experimento foi realizado em uma área de mata, localizada nas dependências do Instituto de Pesquisa Museu Emílio Goeldi, em Belém-Pa. Foi utilizado como isca um suíno (Sus scrofa L. inteiro (com vísceras, de 14,5 Kg, recém abatido. Este foi exposto sob uma armadilha do tipo suspensa modificada, adequada à coletas de insetos adultos, sendo que também foram coletadas larvas e pupas, diretamente na carcaça. A ocorrência dos insetos adultos e de seus estágios larvais foi correlacionada com o tempo de morte do animal, a fim de possibilitar futuras inferências de tempo de morte com base na presença e dispersão destes insetos. O tempo de decomposição e a duração de cada estágio de decomposição foram registrados, tendo sido afetados provavelmente pelo tamanho da carcaça e pela estação do ano. Diferenças quanto ao padrão de sucessão não foram observadas

    Full Text Available Entre fines del siglo XIX y fines del siglo XX se han sucedido en la Ciudad de Buenos Aires diversas formas de institucionalidad local. Leemos este proceso como la particular construcción de una relación de gobierno entre los poderes públicos y los habitantes, en la cual el marco de referencia no es la totalidad de la ciudad, sino sus partes constitutivas, esto es, zonas o barrios. El recorrido por diversos momentos históricos (la federalización de la ciudad, las primeras décadas del siglo XX, el peronismo, los años de su proscripción y la era democrática inaugurada en 1983 permite interpretar las continuidades y rupturas de las formas en que se estructuró esta relación. Con ello queremos contribuir a la comprensión de los diversos modos en que se van estableciendo las relaciones de cercanía o lejanía, tanto territorial como simbólica, entre autoridades públicas y habitantes de la ciudad.

    Full Text Available A presente investigação teve como objetivos: analisar animais presentes em diferentes criações de javalis no estado de São Paulo, com o intuito de auxiliar a identificação de javalis "puros" assim como javalis híbridos provenientes do cruzamento com o suíno doméstico, para tanto foram utilizadas avaliação do fenótipo dos animais, análises citogenéticas e da técnica molecular de RAPD (Random Amplified Polymorphic DNA.O estudo do número de cromossomos nas células diplóides em 104 animais destinados a análise citogenética e fenotípica, revelou polimorfismo de 2n=36, 37 e 38 cromossomos. Por meio da técnica de bandamento GTG foi possível identificação da translocação Robertsoniana entre os cromossomos 15 e 17 como responsável por esse polimorfismo. Todavia, somente com a análise citogenética isolada, não foi possível determinar se a origem desse polimorfismo é decorrente das hibridações com o suíno doméstico ou se são características inerentes ao javali. Contudo, quando associado a análise citogenética com as características fenotípicas, foi possível identificar a existência de hibridações. A análise citogenética nos animais submetidos a técnica de RAPD, revelou 2n=36 cromossomos nos 16 javalis assim como 2n=38 cromossomos nos 11 suínos e, por meio dessa técnica, foram possíveis agrupamentos, separando o suíno doméstico, javali e um possível híbrido revelando-se uma técnica com potencial no auxílio da identificação de híbridos.

    Intrauterine growth restriction (IUGR) may elicit a series of postnatal body developmental and metabolic diseases due to their impaired growth and development in the mammalian embryo/fetus during pregnancy. In the present study, we hypothesized that IUGR may lead to abnormally regulated DNA methylation in the intestine, causing intestinal dysfunctions. We applied reduced representation bisulfite sequencing (RRBS) technology to study the jejunum tissues from four newborn IUGR piglets and their normal body weight (NBW) littermates. The results revealed extensively regional DNA methylation changes between IUGR/NBW pairs from different gilts, affecting dozens of genes. Hiseq-based bisulfite sequencing PCR (Hiseq-BSP) was used for validations of 19 genes with epigenetic abnormality, confirming three genes (AIFM1, MTMR1, and TWIST2) in extra samples. Furthermore, integrated analysis of these 19 genes with proteome data indicated that there were three main genes (BCAP31, IRAK1, and AIFM1) interacting with important immunity- or metabolism-related proteins, which could explain the potential intestinal dysfunctions of IUGR piglets. We conclude that IUGR can lead to disparate DNA methylation in the intestine and these changes may affect several important biological processes such as cell apoptosis, cell differentiation, and immunity, which provides more clues linking IUGR and its long-term complications.

    Vocalizations have long been recognized to encode information about an individual's emotional state and, as such, have contributed to the study of emotions in animals. However, the potential of vocalizations to also encode information about an individual's emotional reactivity has received much less attention. In this study, we aimed to test whether the vocalizations of domestic pigs contain correlates of emotional reactivity that are consistent between different contexts. We recorded vocalizations of 120 young female pigs in an experimental arena in two consecutive recording contexts, social isolation and an encounter with a familiar human. Simultaneously, we measured their heart rate and behaviour to determine their emotional reactivity in the same context (within-context). In addition, we aimed to determine the subjects' emotional reactivity in other contexts (across-context) by measuring their behaviour in four common tests of emotional reactivity, the human approach test, the open door test, the open field test and the novel object test. Using a cluster analysis, we identified four different call types. Significant inter-context correlations were found for all call types, suggesting that pig vocalizations are consistent within an individual across contexts. The call rate and the proportions of the individual call types were found to correlate significantly with indices of emotional reactivity both within and across contexts. Thereby, we found more significant correlations to indices of emotional reactivity within context (behavioural and physiological response during recording) compared to across context (behavioural response in the four emotional reactivity tests). The consistency of the vocal correlates to emotional reactivity between the different contexts depended on the call type. While we found moderate evidence that the high grunt is indicative of more active, more explorative and less fearful individuals both within as well as across contexts, the other call types provided less consistent results. Thus, it seems that some call types are better suited to provide information on a caller's emotional reactivity than others, and further research is needed to clarify the underlying influential factors.

    2017-01-01

    Full Text Available The article presents a comparative analysis of four methods for quantifying the protein-peptide complexes content in extracts obtained from animal raw materials, as well as the low- and highmolecular weight extract fractions: the direct spectrophotometric determination at wavelengths of 260 and 280 nm with subsequent calculation by the Kalckar formula; the biuret reaction by the Kingsley-Weichselbaum method; the method with Bradford reagent and the standard Lowry method. Experimental data analysis demonstrates that in case of the extract that contains protein-peptidic complexes in different molecular weights range, the Kingsley-Weichselbaum method shows the highest quality of protein concentration determination; while studying highmolecular weight fraction (more than 30 kDa, it is possible to obtain more information by combining the spectrophotometric method and the Kingsley-Weichselbaum method. Low-molecular weight fractions (less than 30 kD should be investigated by complex methods including the spectrophotometric method, Lowry and Bradford methods. These methods make it possible to presumably estimate protein molecules size ranges (by amount of peptide bonds, and also to determine hydrophobic and aromatic amino acids presence.

    Pigs were infected with a Bolivian strain of Trypanosoma cruzi (genotype I) and evaluated up to 150 days postinoculation (dpi) to determine the use of pigs as an animal model of Chagas disease. Parasitemia was observed in the infected pigs during the acute phase (15–40 dpi). Anti-T.cruzi immunoglobulin M was detected during 15–75 dpi; high levels of anti-T.cruzi immunoglobulin G were detected in all infected pigs from 75 to 150 dpi. Parasitic DNA was observed by western blot (58%, 28/48) and polymerase chain reaction (27%, 13/48) in urine samples, and in the brain (75%, 3/4), spleen (50%, 2/4), and duodenum (25%, 1/4), but no parasitic DNA was found in the heart, colon, and kidney. Parasites were not observed microscopically in tissues samples, but mild inflammation, vasculitis, and congestion was observed in heart, brain, kidney, and spleen. This pig model was useful for the standardization of the urine test because of the higher volume that can be obtained as compared with other small animal models. However, further experiments are required to observe pathological changes characteristic of Chagas disease in humans. PMID:26928841

  14. Meiotic recombination analyses of individual chromosomes in male domestic pigs (Sus scrofa domestica.

    Directory of Open Access Journals (Sweden)

    Nicolas Mary

    Full Text Available For the first time in the domestic pig, meiotic recombination along the 18 porcine autosomes was directly studied by immunolocalization of MLH1 protein. In total, 7,848 synaptonemal complexes from 436 spermatocytes were analyzed, and 13,969 recombination sites were mapped. Individual chromosomes for 113 of the 436 cells (representing 2,034 synaptonemal complexes were identified by immunostaining and fluorescence in situ hybridization (FISH. The average total length of autosomal synaptonemal complexes per cell was 190.3 µm, with 32.0 recombination sites (crossovers, on average, per cell. The number of crossovers and the lengths of the autosomal synaptonemal complexes showed significant intra- (i.e. between cells and inter-individual variations. The distributions of recombination sites within each chromosomal category were similar: crossovers in metacentric and submetacentric chromosomes were concentrated in the telomeric regions of the p- and q-arms, whereas two hotspots were located near the centromere and in the telomeric region of acrocentrics. Lack of MLH1 foci was mainly observed in the smaller chromosomes, particularly chromosome 18 (SSC18 and the sex chromosomes. All autosomes displayed positive interference, with a large variability between the chromosomes.

    Full Text Available Abstract Quantitative trait loci (QTL affecting carcass and meat quality located on SSC2 were identified using variance component methods. A large number of traits involved in meat and carcass quality was detected in a commercial crossbred population: 1855 pigs sired by 17 boars from a synthetic line, which where homozygous (A/A for IGF2. Using combined linkage and linkage disequilibrium mapping (LDLA, several QTL significantly affecting loin muscle mass, ham weight and ham muscles (outer ham and knuckle ham and meat quality traits, such as Minolta-L* and -b*, ultimate pH and Japanese colour score were detected. These results agreed well with previous QTL-studies involving SSC2. Since our study is carried out on crossbreds, different QTL may be segregating in the parental lines. To address this question, we compared models with a single QTL-variance component with models allowing for separate sire and dam QTL-variance components. The same QTL were identified using a single QTL variance component model compared to a model allowing for separate variances with minor differences with respect to QTL location. However, the variance component method made it possible to detect QTL segregating in the paternal line (e.g. HAMB, the maternal lines (e.g. Ham or in both (e.g. pHu. Combining association and linkage information among haplotypes improved slightly the significance of the QTL compared to an analysis using linkage information only.

    preliminary study on insects associated with pig carcasses was conducted in Phitsanulok, northern Thailand. Five decomposition stages of pig carcasses were categorized: fresh (0-1 day after death), bloated (2 days after death), active (3 days after death), advanced (4- 6 days after death) and dry (7-30 days after death). The arthropod species collected from the corpses in the field sites were mainly classified belonging to two orders and nine families, namely order Diptera (family Calliphoridae: Chrysomya rufifacies and Chrysomya megacephala, family Muscidae: Musca domestica, family Faniidae: Fannia canicularis, family Sarcophagidae: Parasarcophaga ruficornis and family Piophilidae: Piophila casei,) and order Coleoptera (family Dermestidae: Dermestes maculatus, family Histeridae: Hister sp., family Cleridae: Necrobia rufipes and family Trogidae: Trox sp). The forensically dominant fly was C. rufifacies, while the beetle was D. maculatus. The beetles associated with pig carcasses found in this study are first reported in Phitsanulok, Thailand. In addition, ants, bees, spiders and millipedes were also associated with the carcasses. These findings may provide data for further use in legal investigations in Thailand.

    Brucellosis and tularemia are classical zoonotic diseases transmitted from an animal reservoir to humans. Both, wildlife and domestic animals, contribute to the spreading of these zoonoses. The surveillance of the animal health status is strictly regulated for domestic animals, whereas systematic disease monitoring in wildlife does not exist. The aim of the present study was to provide data on the prevalence of anti-Brucella, anti-Francisella and anti-Yersinia antibodies in wild boars from North-Eastern Germany to assess public health risks. A total of 763 sera of wild boars from Mecklenburg-Western Pomerania hunted in 1995/1996 were tested using a commercially available Brucella suis ELISA, an in-house lipopolysaccharide (LPS)-based Francisella ELISA, and commercially available Western blot kits for the detection of anti-Francisella and anti-Yersinia antibodies. The Yersinia enterocolitica O:9 LPS is able to induce serological cross-reactions indistinguishable from brucellosis due to a similar immunodominant epitope in the Brucella O-polysaccharide. The Yersinia Western blot assay was, therefore, based on five recombinant Yersinia outer proteins which have been proved to be specific for the serodiagnosis of yersiniosis. Anti-Brucella, anti-Francisella and anti-Yersinia antibodies were detected in 22.0%, 3.1%, and 62.6% of the wild boars, respectively. The high seroprevalence of tularemia and brucellosis in wild boars indicates that natural foci of these zoonoses are present in wildlife in Germany. However, the impact of transmission of zoonotic pathogens from wildlife to livestock is unknown. Only careful and systematic monitoring will help to prevent the (re)emergence of these zoonotic diseases in domestic animals and consequently human infection.

    Full Text Available In the present study we examined the brain of fetal, newborn, and adult pigs raised for meat production. The fresh and formalin-fixed weights of the brain have been recorded and used, together with body weight, to calculate the Encephalization Quotient (EQ. The weight of the cerebellum has been used to calculate the Cerebellar Quotient (CQ. The results have been discussed together with analogue data obtained in other terrestrial Cetartiodactyla (including the domestic bovine, sheep, goat, and camel, domesticated Carnivora, Proboscidata, and Primates. Our study, based on a relatively large experimental series, corrects former observations present in the literature based on smaller samples, and emphasizes that the domestic pig has a small brain relative to its body size (EQ = 0.38 for adults, possibly due to factors linked to the necessity of meat production and improved body weight. Comparison with other terrestrial Cetartiodactyla indicates a similar trend for all domesticated species.

    Full Text Available We have determined the crystal structure of porcine quinolinate phosphoribosyltransferase (QAPRTase in complex with nicotinate mononucleotide (NAMN, which is the first crystal structure of a mammalian QAPRTase with its reaction product. The structure was determined from protein obtained from the porcine kidney. Because the full protein sequence of porcine QAPRTase was not available in either protein or nucleotide databases, cDNA was synthesized using reverse transcriptase-polymerase chain reaction to determine the porcine QAPRTase amino acid sequence. The crystal structure revealed that porcine QAPRTases have a hexameric structure that is similar to other eukaryotic QAPRTases, such as the human and yeast enzymes. However, the interaction between NAMN and porcine QAPRTase was different from the interaction found in prokaryotic enzymes, such as those of Helicobacter pylori and Mycobacterium tuberculosis. The crystal structure of porcine QAPRTase in complex with NAMN provides a structural framework for understanding the unique properties of the mammalian QAPRTase active site and designing new antibiotics that are selective for the QAPRTases of pathogenic bacteria, such as H. pylori and M. tuberculosis.

    Full Text Available Three feral pig populations inhabiting contrasting environments along the north easterncoast of Australia have been investigated with respect to population structure, individual condition andreproduction. The population on Prince of Wales Island contains a large proportion of juvenile andsub-adult pigs but lacks pigs in the higher age classes. Individuals also breed at an earlier age thananimals of the mainland populations. Pig populations on Cape York Peninsula show a largerproportion of older animals and feral pigs living in rainforest habitats show a low proportion ofanimals in very young and very old age classes. Pigs from the lowland rainforest population are inbetter condition than those of the other populations for most of the year, reflecting the availability offood all year round in this environment. Differences in the population structure of the threepopulations are discussed with respect to fecundity and several mortality factors such as predation anddiseases/parasites.

    Epidemiological studies have reported an association between high iron (Fe) levels and elevated risk of developing type 2 diabetes mellitus (T2D). It is believed that the formation of Fe-catalyzed hydroxyl radicals may contribute to the development of diabetes. Our goal was to determine the effect of a diet with a high Fe content on type 2 diabetic pigs. Four groups of piglets were studied: (1) control group, basal diet; (2) Fe group, basal diet with 3,000 ppm ferrous sulfate; (3) diabetic group (streptozotocin-induced type 2 diabetes) with basal diet; (4) diabetic/Fe group, diabetic animals/3,000 ppm ferrous sulfate. For 2 months, biochemical and hematological parameters were evaluated. Tissue samples of liver and duodenum were obtained to determine mRNA relative abundance of DMT1, ferroportin (Fpn), ferritin (Fn), hepcidin (Hpc), and transferrin receptor by qRT-PCR. Fe group presented increased levels of hematological (erythrocytes, hematocrit, and hemoglobin) and iron parameters. Diabetic/Fe group showed similar behavior as Fe group but in lesser extent. The relative abundance of different genes in the four study groups yielded a different expression pattern. DMT1 showed a lower expression in the two iron groups compared with control and diabetic animals, and Hpc showed an increased on its expression in Fe and diabetic/Fe groups. Diabetic/Fe group presents greater expression of Fn and Fpn. These results suggest that there is an interaction between Fe nutrition, inflammation, and oxidative stress in the diabetes development.

    Bovine tuberculosis (bTB) is a zoonosis caused mainly by Mycobacterium bovis that affects domestic and wild animals. In Brazil, there are no epidemiological studies on tuberculosis in wild animal populations and their possible role in the disease maintenance in cattle herds; thus, the aim of this study was to evaluate the occurrence of tuberculosis in wild boars in Rio Grande do Sul, southern Brazil. Tissue samples of animals hunted under government consent were submitted to histopathology and M. bovis polymerase chain reaction (PCR) as screening tests; the positive samples were subsequently submitted to bacterial isolation, the gold standard diagnosis. Eighty animals were evaluated, of which 27.9% and 31.3% showed histopathological changes and M. bovis genome presence, respectively. Moreover, 23.8% of the animals had at least one organ with isolates classified as Mycobacterium tuberculosis complex (MTC). Three hunting points were risk factors for positive results on screening tests. This study shows the occurrence of tuberculosis in a wild boars' population, and raise the possibility of these animals to play a role as disease reservoirs in southern Brazil. These results may help to improve the Brazilian tuberculosis control programme, as well as elucidate the circulation of mycobacteria in this country. © 2017 Blackwell Verlag GmbH.

    Full Text Available Conjunctival swabs from 44 free-living wild boars culled during a demographic control programme applied in a Regional Park located in the Northern Italy were examined by 16S rRNA encoding gene nested PCR. In total, 22 (50% wild boars were PCR positive. Sequencing of the amplicons identified Chlamydia suis and Chlamydia pecorum in 12 and 5 samples, respectively. For one sample found PCR positive, the nucleotide sequence could not be determined. Four conjunctival samples showed ≥ 92% sequence similarities to 16S rRNA sequences from Chlamydia-like organisms, as did large intestine, uterus, and vaginal swabs from the same four animals. Amoeba DNA was found in one Chlamydia-like organism positive conjunctival swab. To our knowledge, this is the first detection of members of the Parachlamydiaceae family in wild boars, confirming a large animal host range for Chlamydia-like organisms.

    Full Text Available Our aim was to evaluate the risk of human toxoplasmosis via meat consumption from wild boars by estimating the seroprevalence of Toxoplasma gondii in animals hunted in central Italy. Using a modified agglutination test, 213 sera from wild boars were examined for anti-Toxoplasma IgG antibodies. Diaphragm samples (n=65 from seropositive and seronegative animals were tested by nested-PCR to detect T. gondii DNA. Toxoplasma DNA from diaphragms was genotyped by PCR-RFLP using 12 genetic markers. Moreover, the aim of the study was also to identify helminth infections of wild boars in the selected area and to evaluate their hazard for humans. Examination of sera revealed a seroprevalence of 12.2%. Only one T. gondii strain could be genotyped from a seropositive animal and PCR-RFLP revealed that it belonged to type II. Analysis of 50 samples of faeces and 32 small intestines revealed that 78% and 15.6% of the samples harboured parasites, respectively, with the occurrence of parasites potentially dangerous for humans. These latter included Ascaris suum, Macracanthorhynchus hirudinaceus, Trichuris suis, and Metastrongylus spp. A significant association was found between coprological positivity and male sex. These results indicate that T. gondii infection may be present in wild boar tissues and consumption of undercooked or raw wild boar meat may expose humans to risk of toxoplasmosis in the study area. Furthermore, the study highlights that wild boars are hosts of helminths of veterinary and medical importance transmissible to pigs and humans.

    Full Text Available The molecular markers have shown their great utility in the characterization of the domestic animals, hence, the objective of this work was to characterize, genetically, the Creole pig of Ecuador by means of microsatellites. Samples of hair of 15 animals were gathered. A panel of 25 microsatellites, the amplification of the same was carried out by means of the reaction in chain of the polymerase and the amplified fragments, separated by electrophoresis in gels of polyacrylamide. In addition, were calculated the half number of alleles by locus (MNA, the allelic frequencies, the expected (He and the observed (Ho heterozygosity , the content of polymorphic information (PIC, as well as the balance Hardy-Weinberg (EHW and the FIS for marker. The half number of alleles found by locus has been of 6.2 and the percentage of individual heterozygote behaved above of 60%. Of the entirety of the studied loci the 68% showed a high PIC. These results show that the Ecuadorian Creole pig possesses a high genetic diversity, essential information to optimize the national strategies of conservation and it improvement of this genotype in Ecuador.

    In the European Union, various fluoroquinolones are authorised for the treatment of food producing animals. Each administration poses an increased risk of development and spread of antimicrobial resistance. The aim of this study was to investigate the impact of parenteral administration of enrofloxacin on the prevalence of enrofloxacin and ciprofloxacin susceptibilities in the commensal intestinal E. coli population. E. coli isolates from faeces of twelve healthy pigs were included. Six pigs were administered enrofloxacin on day 1 to 3 and after two weeks for further three days. The other pigs formed the control group. MIC values were determined. Virulence and resistance genes were detected by PCR. Phylogenetic grouping was performed by PCR. Enrofloxacin and ciprofloxacin were analysed in sedimentation samples by HPLC. Susceptibility shifts in commensal E. coli isolates were determined in both groups. Non-wildtype E. coli could be cultivated from two animals of the experimental group for the first time one week after the first administration and from one animal of the control group on day 28. The environmental load with enrofloxacin in sedimentation samples showed the highest amount between days one and five. The repeated parenteral administration of enrofloxacin to pigs resulted in rapidly increased MIC values (day 28: MIC up to 4 mg/L, day 35: MIC ≥ 32mg/L). E. coli populations of the control group in the same stable without direct contact to the experimental group were affected. The parenteral administration of enrofloxacin to piglets considerably reduced the number of the susceptible intestinal E. coli population which was replaced by E. coli strains with increased MIC values against enrofloxacin. Subsequently also pigs of the control were affected suggesting a transferability of strains from the experimental group through the environment to the control group especially as we could isolate the same PFGE strains from both pig groups and the environment.

    The obtained results indicate that consumption of raw or undercooked meat from wild boars can carry an important risk of toxoplasma infection. Post mortem detection of antibodies in meat juice samples using ELISA is a useful alternative to blood serum examination. In addition, a diaphragm sample has been well-proven as a matrix sample for the contemporaneous diagnostics of trichinellosis and toxoplasmosis.

    Full Text Available The diversity of olfactory binding proteins (OBPs is a key point to understand their role in molecular olfaction. Since only few different sequences were characterized in each mammalian species, they have been considered as passive carriers of odors and pheromones. We have explored the soluble proteome of pig nasal mucus, taking benefit of the powerful tools of proteomics. Combining two-dimensional electrophoresis, mass spectrometry and western-blot with specific antibodies, our analyses revealed for the first time that the pig nasal mucus is mainly composed of secreted OBP isoforms, some of them being potentially modified by O-GlcNAcylation. An ortholog gene of the glycosyltransferase responsible of the O-GlcNAc linking on extracellular proteins in Drosophila and Mouse (EOGT was amplified from tissues of pigs of different ages and sex. The sequence was used in a phylogenetic analysis, which evidenced conservation of EOGT in insect and mammalian models studied in molecular olfaction. Extracellular O-GlcNAcylation of secreted OBPs could finely modulate their binding specificities to odors and pheromones. This constitutes a new mechanism for extracellular signaling by OBPs, suggesting that they act as the first step of odor discrimination.

    Thomas Cucchi

    Full Text Available Pigs have played a major role in the economic, social and symbolic systems of China since the Early Neolithic more than 8,000 years ago. However, the interaction between the history of pig domestication and transformations in Chinese society since then, have not been fully explored. In this paper, we investigated the co-evolution from the earliest farming communities through to the new political and economic models of state-like societies, up to the Chinese Empire, using 5,000 years of archaeological records from the Xiawanggang (XWG and Xinzhai (XZ sites (Henan Province. To trace the changes of pig populations against husbandry practices, we combined the geometric morphometric analysis of dental traits with a study of the stable carbon and nitrogen isotope ratios from bone collagen. The domestication process intensified during the Neolithic Yangshao, prompted by greater selective pressure and/or better herd control against wild introgression. After that, pig farming, in XWG, relied on local livestock and a gradual change of husbandry practices overtime. This was characterized by a gentle increase in millet foddering and animal protein intake, until a complete change over to household management during the Han dynasty. The only rupture in this steady trend of husbandry occurred during the Longshan period, with the appearance of small sized and idiosyncratic pigs with specific feeding practices (relying on millet and household scraps. From three exploratory hypothesis, we explored the possibility of anti-elite pig production in XWG during the Longshan period, as a means to resist incorporation into a new economic model promoting intensified domestic production. This exploratory hypothesis is the most suitable to our dataset; however, numerous areas need to be explored further in order to adequately document the role of pigs in the rise of China's complex societies.

    Matthew S Conrad

    Full Text Available Due to the fact that morphology and perinatal growth of the piglet brain is similar to humans, use of the piglet as a translational animal model for neurodevelopmental studies is increasing. Magnetic resonance imaging (MRI can be a powerful tool to study neurodevelopment in piglets, but many of the MRI resources have been produced for adult humans. Here, we present an average in vivo MRI-based atlas specific for the 4-week-old piglet. In addition, we have developed probabilistic tissue classification maps. These tools can be used with brain mapping software packages (e.g. SPM and FSL to aid in voxel-based morphometry and image analysis techniques. The atlas enables efficient study of neurodevelopment in a highly tractable translational animal with brain growth and development similar to humans.

    Full Text Available The aim of our project was to study the effect of streptozotocin (STZ—induced hyperglycemia on sciatic nerve morphology, blood plasma markers and immunohistochemical expression of RAGE (the Receptor for Advanced Glycation End-products, and its ligands—S100B and Carboxymethyl Lysine (CML-advanced glycation endproduct (AGE in the laboratory pig. Six months after STZ—injections, blood plasma measurements, morphometric analysis of sciatic nerve fiber density, immunofluorescent distribution of potential molecular neuropathy contributors, ELISA measurement of plasma AGE level and HPLC analysis of sciatic nerve levels of one of the pre-AGE and the glycolysis intermediate products—methyl-glyoxal (MG were performed. The results of our study revealed that STZ—injected animals displayed elevated levels of plasma glucose, gamma glutamyl transferase (GGT and triglycerides. The sciatic nerve of STZ-injected pigs revealed significantly lower numbers of small-diameter myelinated fibers, higher immunoreactivity for RAGE and S100B and increased levels of MG as compared to control animals. Our results correspond to clinical findings in human patients with hyperglycemia/diabetes-evoked peripheral neuropathy and suggest that the domestic pig may be a suitable large animal model for the study of mechanisms underlying hyperglycemia-induced neurological complications in the peripheral nerve and may serve as a relevant model for the pre-clinical assessment of candidate drugs in neuropathy.

    Full Text Available The identification of the genotypes of Echinococcus granulosus present in livestock and wild animals within regions endemic for cystic echinococcosis (CE is epidemiologically important. Individual strains display different biological characteristics that contribute to outbreaks of CE and that must be taken into account in the design of intervention programs. In this study, samples of hydatid cysts due to E. granulosus were collected from alpacas (4 in Puno and pigs (8 in Ayacucho in Peru, an endemic region for CE. Polymerase chain reaction amplification and DNA sequencing of specific regions of the mitochondrial cytochrome C oxidase subunit 1 and NADH dehydrogenase subunit 1 genes confirmed the presence of a strain common to sheep, the G1 genotype, in alpacas. Two different strains of E. granulosus were identified in pigs: the G1 and the G7 genotypes. This is the first report of the G1 genotype of E. granulosus in alpacas in endemic regions of CE in Peru.

    During disease outbreaks, core temperature is a useful health metric in swine, due to the presence of pyrexia especially during the acute phase of infection. Despite technologic advances in other facets of swine production and health management, rectal thermometry continues to be the ‘gold standard’ for measuring core body temperature. However, for various reasons, collecting rectal temperatures can be difficult and unsafe depending on the housing modality. In addition, the delay between insertion of the rectal thermometer and obtaining a reading can affect measurement accuracy, especially when the pig requires physical restraint. Clearly safer, faster, and more accurate and precise temperature acquisition methods that necessitate minimal or no handling of swine are needed. We therefore compared rectal thermometers, subcutaneous microchips, and an inexpensive handheld infrared thermometer by measuring the core body temperature of 24 male castrated piglets at random intervals over a 5-wk period. The core body temperature (mean ± 1 SD) was 39.3 ± 0.5 °C by rectal thermometry, 39.0 ± 0.7 °C by microchip transponder, and 34.3 ± 1.0 °C by infrared thermometry; these 3 values differed significantly. Although the readings obtain by using infrared thermometry were numerically lower than those from the other methods, it is arguably the safest method for assessing the core temperature of swine and showed strong relative correlation with rectal temperature.

    Full Text Available vThis study was aimed at analysing the most relevant environmental variables involved in vehicle–wild boar road collisions in a Mediterranean area, starting from a territorial information system implemented in a GIS environment. Landscape structure indices and local qualitative and quantitative variables were correlated to identify the most frequent predisposing factors of collisions. Statistical tests of the considered parameters indicated a higher frequency of collisions in the evening hours of late summer and autumn (P<0.05 compared with daytime and night-time, localized nearness to attraction points (feeding or resting sites; P<0.001 and closeness to no-hunting areas (P<0.001. In addition, local road parameters (shape of road, visibility at road sides, etc. considerably increased the risk of collisions.

Main plant assemblages of the exclusion zone of the Chernobyl accident are analyzed for their significance in the diet of a wild boar. Special attention is paid to the role of underground forage (35% of average annual forage), and to consumption of Oenotera biennis roots comprising 26% of average annual forage. Recent state of the forage base and of the wild boar population is estimated. An attempt to predict its dynamics for the nearest 10-15 years is made

    Hydroxocobalamin is a Food and Drug Administration-approved antidote for cyanide poisoning. Cobinamide is a potential antidote that contains 2 cyanide-binding sites. To our knowledge, no study has directly compared hydroxocobalamin with cobinamide in a severe, cyanide-toxic large-animal model. Our objective is to compare the time to return of spontaneous breathing in swine with acute cyanide-induced apnea treated with intravenous hydroxocobalamin, intravenous cobinamide, or saline solution (control). Thirty-three swine (45 to 55 kg) were intubated, anesthetized, and instrumented (continuous mean arterial pressure and cardiac output monitoring). Anesthesia was adjusted to allow spontaneous breathing with FiO2 of 21% during the experiment. Cyanide was continuously infused intravenously until apnea occurred and lasted for 1 minute (time zero). Animals were then randomly assigned to receive intravenous hydroxocobalamin (65 mg/kg), cobinamide (12.5 mg/kg), or saline solution and monitored for 60 minutes. A sample size of 11 animals per group was selected according to obtaining a power of 80%, an α of .05, and an SD of 0.17 in mean time to detect a 20% difference in time to spontaneous breathing. We assessed differences in time to death among groups, using Kaplan-Meier estimation methods, and compared serum lactate, blood pH, cardiac output, mean arterial pressure, respiratory rate, and minute ventilation time curves with repeated-measures ANOVA. Baseline weights and vital signs were similar among groups. The time to apnea and cyanide dose required to achieve apnea were similar. At time zero, mean cyanide blood and lactate concentrations and reduction in mean arterial pressure from baseline were similar. In the saline solution group, 2 of 11 animals survived compared with 10 of 11 in the hydroxocobalamin and cobinamide groups (Pcyanide concentrations became undetectable at the end of the study in both antidote-treated groups, and no statistically significant differences were detected between the 2 groups for mean arterial pressure, cardiac output, respiratory rate, lactate, or pH. Both hydroxocobalamin and cobinamide rescued severely cyanide-poisoned swine from apnea in the absence of assisted ventilation. The dose of cobinamide was one fifth that of hydroxocobalamin.

    Full Text Available Blood samples for determining of epinephrine concentration and biochemical parameters in the blood serum of wild boars were taken from 42 healthy wild boars, both sexes, during the hunting season. All animals in good condition, body weight 20 to 95 kg, were divided into two groups up to 50 kg (group A and up to 95 kg (Group B. Epinephrine concentration was determined by ELISA twice: one week after taking samples and a month after repeated freezing at -80°C. It was higher in relation to the reference value of domestic pigs and human (109.45 pg/ml in A and 119.54 pg/ml in B group. Repeated freezing and re-analysis after a month were resulted in lower concentrations of epinephrine (12% in young and 11.17% in adult animal, but without statistical significance (P>0.05. Biochemical analysis results’ show increased glucose and triglycerides concentrations compared to the reference values, while other indicators were observed within or slightly increased referring to the normal range. The correlation between glucose and epinephrine was not determined.

    The objective of this study was to identify the bioserotypes and virulence markers of Yersinia enterocolitica strains isolated from wild boars in Poland. Bacteriological examination of 302 rectal swabs from 151 wild boars resulted in the isolation of 40 Y. enterocolitica strains. The majority of the examined strains (n = 30), belonged to bioserotype 1A/NI. The presence of individual Y. enterocolitica strains belonging to bioserotypes 1B/NI (3), 1A/O:8 (2), 1A/O:27 (2), 2/NI (1), 2/O:9 (1) and 4/O:3 (1) was also demonstrated. Amplicons corresponding to ail and ystA genes were observed only in one Y. enterocolitica strain--bioserotype 4/O:3. The ail and ystB gene amplicons were noted in 11 Y. enterocolitica biotype 1A strains, although single amplicons of ystB gene were found in 28 of the tested samples. In four out of eight cases when two Y. enterocolitica strains were isolated from the same animal, the strains differed in biotype, serotype or virulence markers. The European population of wild boars continues to grow and spread to new areas, therefore, wild boars harbouring potentially pathogenic Y. enterocolitica 4/O:3 strains pose a challenge to public health.

    Full Text Available Advances on research, technology and applications for detergent processes increase rapidly. They keep provoking, as during last decades, repercussions on several fields (domestic, industrial, sanitary, energetic, environmental, legislative. To control as much as possible these repercussions, it is necessary to assess the actual knowledge about detergency mechanisms. This informative article starts by reviewing the essential elements for detergent processes (substrate, soil, cleaning bath. Subsequently several physico-chemical key factors for effectiveness of the textile washing are discussed. These factors are: a removal of liquid oily soils (by rolling-up, or by spontaneous microemulsification; b separation of solid particles (by interfacial or electrostatic interactions; c antiredeposition effects (by solubilization, emulsification or suspension; d water hardness influence; e washing physical conditions (temperature, agitation, time. The article ends by establishing the necessity for maintaining close collaboration among experts on different fields to optimize both detergent processes and their repercussions.

    Full Text Available The first medical and surgical experiences of donating and transplanting body parts generated a new concept and perception of the human body as a territorialized and capitalized unit, composed of replaceable and functional parts. The press articles analyzed in this research reveal how, during the first half of the XXth century, Franco’s government and the Catholic doctrine, as well as the coalition of political, clerical and scientific hegemony, led to the cultural construction of donation as a proof of charity and Christian love and to an interpretation of the human body as a common good, available to serve others.Los primeros antecedentes médico-quirúrgicos de donación y trasplante de partes del cuerpo, dieron lugar a una concepción y vivencia del cuerpo humano como conjunto territorializado y capitalizado de partes reemplazables y funcionales. En los artículos de prensa analizados en este trabajo se estudia cómo, en la primera mitad del siglo XX, los preceptos y normas del régimen franquista y de la doctrina católica, así como la alianza entre hegemonía política, eclesiástica y científica, generaron la construcción cultural de la donación como muestra de caridad y amor cristiano y la percepción del cuerpo como bien común al servicio del prójimo.

  1. Humans (Homo sapiens) judge the emotional content of piglet (Sus scrofa domestica) calls based on simple acoustic parameters, not personality, empathy, nor attitude toward animals.

    The vocal expression of emotion is likely driven by shared physiological principles among species. However, which acoustic features promote decoding of emotional state and how the decoding is affected by their listener's psychology remain poorly understood. Here we tested how acoustic features of piglet vocalizations interact with psychological profiles of human listeners to affect judgments of emotional content of heterospecific vocalizations. We played back 48 piglet call sequences recorded in four different contexts (castration, isolation, reunion, nursing) to 60 listeners. Listeners judged the emotional intensity and valence of the recordings and were further asked to attribute a context of emission from four proposed contexts. Furthermore, listeners completed a series of questionnaires assessing their personality (NEO-FFI personality inventory), empathy [Interpersonal Reactivity Index (IRI)] and attitudes to animals (Animal Attitudes Scale). None of the listeners' psychological traits affected the judgments. On the contrary, acoustic properties of recordings had a substantial effect on ratings. Recordings were rated as more intense with increasing pitch (mean fundamental frequency) and increasing proportion of vocalized sound within each stimulus recording and more negative with increasing pitch and increasing duration of the calls within the recording. More complex acoustic properties (jitter, harmonic-to-noise ratio, and presence of subharmonics) did not seem to affect the judgments. The probability of correct context recognition correlated positively with the assessed emotion intensity for castration and reunion calls, and negatively for nursing calls. In conclusion, listeners judged emotions from pig calls using simple acoustic properties and the perceived emotional intensity might guide the identification of the context.

    Gondret, Florence; Lebret, Bénédicte

    2007-06-01

    This study aimed to investigate whether feed restriction and re-alimentation differently affect lipid content and activities of lipogenic or catabolic enzymes according to muscle types in pigs. At around 28 kg body mass (BW), sixty pigs (n=30 per group) were allocated to either ad libitum (AL) or restricted/re-feeding (RA) regimens. After feed restriction (80 kg BW), lipid content was reduced (P<0.01) in the oxidative rhomboideus (RH) as in the glycolytic biceps femoris (BF) muscles of RA pigs compared with AL pigs. Lower activities (P<0.05) of the lipogenic enzymes fatty acid synthase (FAS) and malic enzyme (ME) were observed in the RH but not in the BF of RA vs. AL pigs. After re-feeding (110 kg BW), lipid content was restored in the RH, but was still 12% lower (P<0.05) in the BF of RA compared with AL pigs. In the RH, the trend for an enhanced FAS activity and for a smaller weight-related decrease of ME activity in RA pigs than AL pigs during re-feeding, may have contributed to the muscle fat recovery observed in the RA pigs. In the BF, higher oxidative enzyme activities (P<0.10) in RA pigs compared to AL pigs might explain the incomplete lipid recovery observed after re-feeding in the former animals. In conclusion, metabolic activities in response to restriction and re-feeding differed according to muscle metabolic type.

    The DNA template used in the pig genome sequencing project was provided by a Duroc pig named TJ Tabasco. In an effort to annotate microRNA (miRNA) genes in the reference genome we have conducted deep sequencing to determine the miRNA transcriptomes in ten different tissues isolated from Pinky......, a genetically identical clone of TJ Tabasco. The purpose was to generate miRNA sequences that are highly homologous to the reference genome sequence, which along with computational prediction will improve confidence in the genomic annotation of miRNA genes. Based on homology searches of the sequence data...... against miRBase, we identified more than 600 conserved known miRNA/miRNA*, which is a significant increase relative to the 211 porcine miRNA/miRNA* deposited in the current version of miRBase. Furthermore, the genome-wide transcript profiles provided important information on the relative abundance...

    Full Text Available The faunal assemblage from the 9(th-8(th millennium BP site at Sha'ar Hagolan, Israel, is used to study human interaction with wild suids and cattle in a time period just before the appearance of domesticated animals of these species in the Jordan Valley. Our results, based on demographic and osteometric data, indicate that full domestication of both cattle and suids occurred at the site during the 8(th millennium. Importantly, domestication was preceded in both taxa by demographic and metric population parameters indicating severe overhunting. The possible role of overhunting in shaping the characteristics of domesticated animals and the social infrastructure to ownership of herds is then explored.

    Full Text Available The objective of this study was to examine iodine and selenium contents in skeletal muscles of selected species of game animals living in regions with low iodine and selenium contents in the soil and water. Iodine content was determined in 66 samples of skeletal muscles of red deer cut out of the musculus gracilis, 32 samples and 27 samples from the same muscle of roe deer and wild boar, respectively. The shot game animals came from hunting grounds in western and southern regions of the Czech Republic and in Protected Landscape Area Šumava. In red deer muscles the average iodine content was 44.9 ± 15.2 μg I·kg-1 wet weight with the range of 6.9 to 82.0 μg I·kg-1. The lower concentration in roe deer meat with the average 39.3 ± 14.1 μg I·kg-1 and the range from 18.3 to 84.4 μg I·kg-1 may be due to differences between biotopes and food. The average iodine concentration in the musculus gracilis of wild boars was 55.9± 27.0 μg·kg-1 wet weight. Selenium content was determined in 22 samples of red deer, 51 samples of roe deer and 27 samples of wild boar skeletal muscles. The average values of selenium content in the meat of red deer, roe deer and wild boars were 16.2 ± 8.4, 36.9 ± 16.6 and 27.6 ± 19.8 μg Se·kg-1 wet weight, respectively. All three species of game animals are characterised by low content and high variability of selenium concentration in meat with the minimum value 3.9 µg and maximum value 83.3 μg·kg-1 wet weight. The study brings new data on iodine and selenium content in the muscle of game animals in the Czech Republic.

    Full Text Available The aim of the present study was to determine heavy metal reference levels for exposure and risk assessment studies on a local scale. The average levels of cadmium recorded in 75 wild boars were 0.085, 0.079 and 1.052 mg Cd kg-1 wet weight (w.w. in the liver, muscle and kidney, respectively. The majority of the muscle samples and some of the liver samples contained levels of heavy metal that were over the legal limit [EU Maximum Residue Levels (MRLs] for pigs. Our data are similar to or lower than the values reported in most of the available literature. For Pb concentration, the average values recorded were 0.318, 0.126 and 0.298 mg kg kg-1 ww.w. in the liver, muscle and kidney, respectively. The samples that were non-compliant with regulatory limits (MRLs for pigs were registered only for muscle. Available data on the presence of Pb content in game meat report lower values than ours, most likely because the area around the bullet path was avoided while sampling. The average values of total Cr were 0.141, 0.139 and 0.097 mg Cr kg-1 w.w. in the liver, muscle and kidney, respectively. For Zn, the mean values were 49.76, 53.21 and 32.46 mg kg-1 w.w. in liver, muscle and kidney, respectively. Cu content was 46.12, 12.20 and 5.64 mg kg-1 w.w. in the liver, muscle and kidney, respectively. The results obtained have been validated on the basis of the scarce and inconsistent Italian literature available and on international studies.

    Full Text Available The parallel growth of urban areas and wild boar populations in recent years has increased the presence of this species around cities and in suburban areas, often leading to conflict with local people. In the Collserola Natural Park, situated within the metropolitan area of Barcelona, wild boar have become habituated to humans and urban settings because of direct feeding by local residents. Their attraction to these areas due to an abundance of anthropogenic food sources is especially strong during the warmer summer season when foraging conditions are poorer in their natural woodland habitat; the number of captures of habituated wild boar in peri–urban areas is significantly correlated with mean monthly temperatures. Habituated boar are primarily matriarchal groups, whereas adult and sub–adult (>1 year males are significantly less represented than in non–habituated boars. In Collserola, habituated sub–adult and adult females are significantly heavier than their non–habituated counterparts and these weight differences increase with age; in the > 3 year–old age class they may be 35% heavier. Conflicts generated by the presence of wild boar in peri–urban areas are complex, and the responses by authorities are similarly diverse and often exacerbated by ambivalent public attitudes, both towards wild boar presence and applied mitigation measures. By 2010, at least 44 cities in 15 countries had reported problems of some kind relating to the presence of wild boar or feral pigs.

    Oral mass vaccination (OMV) is considered as an efficient strategy for controlling classical swine fever (CSF) in wild boar. After the completion of vaccination, the presence of antibodies in 6-12 month-old hunted wild boars was expected to reflect a recent CSF circulation. Nevertheless, antibodies could also correspond to the long-lasting of maternal antibodies. This paper relates an experience of surveillance which lasted 4 years after the completion of OMV in a formerly vaccinated area, in north-eastern France (2010-2014). First, we conducted a retrospective analysis of the serological data collected in 6-12 month-old hunted wild boars from 2010 up to 2013, using a spatial Bayesian model accounting for hunting data autocorrelation and heterogeneity. At the level of the whole area, seroprevalence in juvenile boars decreased from 28% in 2010-2011 down to 1% in 2012-2013, but remained locally high (above 5%). The model revealed the existence of one particular seroprevalence hot-spot where a longitudinal survey of marked animals was conducted in 2013-2014, for deciphering the origin of antibodies. Eleven out of 107 captured piglets were seropositive when 3-4 months-old, but their antibody titres progressively decreased until 6-7 months of age. These results suggest piglets were carrying maternal antibodies, few of them carrying maternal antibodies lasting until the hunting season. Our study shows that OMV may generate confusion in the CSF surveillance several years after the completion of vaccination. We recommend using quantitative serological tools, hunting data modelling and capture approaches for better interpreting serological results after vaccination completion. Surveillance perspectives are further discussed.

    Full Text Available Gills arches of the freshwater fish Prochilodus scrofa Steindachner, 1881 (Lt= 8.0-12.4cm were removed to be analyzed in a scanning electron microscope. The morphology of the superficial structures of the gill filaments and pharyngeal region of the gills arches was discussed and related to their functional aspects. A great quantity of mucous secretory cells and of microridges, along with the pavement cell surface of the primary lamellae and branchial pharyngeal region, indicate the existence of a protection strategy of the respiratory lamellae. The chloride cells are abundant, specially on the distal portion of the primary lamellae, and bring out the osmo regulatory capacity of this species. This fish seems not to be a filtering one according to: its short and simple gill rakers; presence of several taste buds turned towards the mouth opening; evidence of spines on the external side of the arches and an abundant secretion of mucous in the pharyngeal region. This species probably selects the food to be swallowed through its chemical receptors and retains it with the help of spines and mucous secretion this way protecting the gills filaments against the rubbing of particles over them.

    Full Text Available Considerable importance has been given to nest construction and larval food transport to the nest as a precondition for the eusociality of insects. Most adult hymenopterans feed on liquids, although bees and a few wasps may also feed on pollen. Carrion represents an additional source of protein for some species and they will scavenge for dead animals in the wild. This paper aims at analyzing Hymenoptera visitors on a pig carcass during the process of decomposition, in the summer of 2005 and the winter of 2006 in Brazil, and comparing the results with other studies in the Neotropical region. To our knowledge, this is the first study which described the occurence of Agelaia pallipes, Polybia paulista and Scaptotrigona depilis on decomposing carcasses in southeastern Brazil. It also raises the hypothesis of possible applications of Hymenoptera to achieve more precise PMI estimations, apart from other insects already known as having great importance in such estimates.Considerável importância tem sido dada às construções de ninhos e transporte de alimento larval para o ninho como uma pré-condição para a eusociabilidade dos insetos. Muitos adultos de himenópteros alimentam-se em líquidos, embora as abelhas e poucas vespas podem também se alimentarem de pólen. Carcaças representam uma fonte adicional de proteína para algumas espécies e elas foram uma vez observadas se alimentando de animais mortos na natureza. Este trabalho tem por objetivo analisar Hymenoptera visitantes em carcaças de porcos durante o verão de 2005 e inverno de 2006 no Brasil, ao longo dos estágios de decomposição, comparando com resultados de outros estudos na região Neotropical. Pelo nosso conhecimento, esse é o primeiro estudo que descreveu a ocorrência de Agelaia pallipes, Polybia paulista e Scaptotrigona depilis em carcaças em decomposição no sudeste do Brasil. Isso também aumenta a hipótese na possibilidade de aplicação de Hymenoptera em auxiliar a estimar o IPM de maneira mais precisa, sem levar em conta insetos que já possuem grande importância forense.

    Full Text Available The Greek philosophy developed three types of philosophical schools. The first one, represented by the Milesians, the Eleatics and partly the Aristotle’s Lyceum, understands the philosophical activity as a set of projects of investigation, not necessarily lacking of pragmatic interest, moved by desire to explain the phenomena. Next to their activities of investigation, many of these philosophers maintain a political activity within the framework of their own cities. The second type, represented by the Pythagoreans and the Academy of Plato, aims to reach the union between knowledge and political power. This proposal finds its better synthesis in the ideal of philosopher king. At the hellenistic period, the goal of philosophical schools would be to offer the cultivated and instructed man a particular way of life.La filosofía griega desarrolló tres tipos de escuelas filosóficas. El primero, representado por los milesios, los eleáticos y, en parte, el Liceo de Aristóteles, entiende la actividad filosófica como un conjunto de proyectos de investigación, no necesariamente carentes de interés pragmático, movidos por el deseo de explicar los fenómenos. Junto a sus actividades de investigación, muchos de estos filósofos mantienen una actividad política en el marco de las instituciones de sus propias ciudades. El segundo tipo, representado por los pitagóricos y la Academia platónica, se propone alcanzar la unión entre el saber y el poder. Esta propuesta halla su mejor síntesis en el ideal del filósofo rey. Finalmente, en la época helenística, las escuelas filosóficas se proponen sobre todo ofrecer un ideal de vida al hombre culto e instruido de su tiempo.

    The distribution of residual stress of SUS304 samples that were undergone TIG welding process with four different electric currents has been measured. The welding has been done in the middle part of the samples that was previously grooved by milling machine. Before they were welded the samples were annealed at 650 degree Celsius for one hour. The annealing process was done to eliminate residual stress generated by grooving process so that the residual stress within the samples was merely produced from welding process. The calculation of distribution of residual stress was carried out by measuring the strains within crystal planes of Fe(220) SUS304. Strain, Young modulus, and Poisson ratio of Fe(220) SUS304 were measured using DN1-M neutron diffractometer. Young modulus and Poisson ratio of Fe(220) SUS304 sample were measured in-situ. The result of calculations showed that distribution of residual stress of SUS304 in the vicinity of welded area is influenced both by treatments given at the samples-making process and by the electric current used during welding process.

    SUS-MI cables are the inorganic insulation cables using austenitic stainless steel SUS 321 as the sheath, oxygen-free copper as the conductor and high purity magnesium oxide as the insulatingmaterial. Because of the excellent characteristics of the composing materials, the properties withstanding radiation, fire and heat, and sodium of the cables are superior. In the nuclear power facilities being developed such as fast breeder reactors and nuclear fusion reactors, there is the environment the cables with organic materials as the components cannot meet. As the cables to be applied to such places, the SUS-MI cables are most suitable. In this report, the electric properties and the mechanical strength of the cables and the examples of practical use are described. The highest temperature of using the SUS-MI cables is 800 deg C. The form and the composing materials of the SUS-MI cables, the characteristics and the cable laying are reported. Ceramic connectors and heat-resistant wall penetration parts were developed. The characteristics of the cables for the preheaters of fast breeder reactors are compared. (Kako, I.)

  13. First Ecological Study of the Bawean Warty Pig (Sus blouchi, One of the Rarest Pigs on Earth.

    Mark Rademaker

    Full Text Available The Bawean warty pig (Sus blouchi is an endemic pig species confined to the 192 km(2 large island of Bawean in the Java Sea, Indonesia. Due to a lack of quantitative ecological research, understanding of natural history and conservation requirements have so far been based solely on anecdotal information from interviews with local people and study of captive and museum specimens. In this study we provide the first assessment of population and habitat preferences for S. blouchi by using camera trapping. From the 4th of November 2014 to January 8th 2015, we placed camera traps at 100 locations in the forested protected areas on Bawean. In 690.31 camera days (16567.45 hours we captured 92 independent videos showing S. blouchi. Variation in S. blouchi trapping rates with cumulative trap effort stabilized after 500 camera days. An important outcome is that, in contrast to the suggestion of previous assessments, only S. blouchi was detected and no S. scrofa was found, which excludes hybridization threats. We fitted a Random Encounter Model, which does not require the identification of individual animals, to our camera-trapping data and estimated 172-377 individuals to be present on the island. Activity patterns and habitat data indicate that S. blouchi is mainly nocturnal and prefers community forests and areas near forest borders. Next to this, we found a positive relationship between S. blouchi occupancy, distance to nearest border, litter depth and tree density in the highest ranking occupancy models. Although these relationships proved non-significant based on model averaging, their presence in the top ranking models suggests that these covariables do play a role in predicting S. blouchi occurrence on Bawean. The estimated amount of sites occupied reached 58%. Based on our results, especially the estimation of the population size and area of occupancy, we determine that the species is Endangered according to the IUCN/SSC Red List criteria.

Extravascular lung water (EVLW elevation and levels of interleukin-8 (IL-8 and vascular cell adhesion molecule-1 (VCAM-1 have been studied as indicators playing a role in the pathogenesis of ARDS. The aim of the study was to determine the effects of colloid or crystalloid on the incidence of ARDS, elevation of EVLW, and levels of IL-8 and VCAM-1, in swine models with severe sepsis.Methods: This was a randomized trial conducted at the Laboratory of Experimental Surgery, School of Veterinary Medicine, IPB, using 22 healthy swine models with a body weight of 8 to 12 kg. Subjects were randomly allocated to receive either colloid or crystalloid fluid resuscitation. After administration of endotoxin, clinical signs of ARDS, EVLW, IL-8, and VCAM-1 were monitored during sepsis, severe sepsis, and one- and three hours after fluid resuscitation. Analysis of data using the Wilcoxon test , Kolmogorov-Smirnov test, Mann-Whitney test, unpaired t test.Results: Mild ARDS was more prevalent in the colloid group, while moderate ARDS was more frequent in the crystalloid group. EVLW elevation was lower in the colloid compared to the crystalloid group. There was no significant difference in IL-8 and VCAM-1 levels between the two groups.Conclusion: The use of colloids in fluid resuscitation does not decrease the probability of ARDS events compared to crystalloids. Compared to crystalloids, colloids are associated with a lower increase in EVLWI, but not with IL-8 or VCAM-1 levels.

Pero, a final de cuentas, es cuestionable si su imagen como pueblo “originario” y conservacionista “innato” les ayude en el largo plazo, ya que forma parte de un discurso fundamentalmente colonialista y puede limitar las oportunidades de las comunidades lacandonas a decidir su futuro y definir el carácter de su inserción en la sociedad nacional.

    Full Text Available La enfermedad injerto contra huésped es la principal complicación que sufren los pacientes que han recibido trasplante alogénico. Se produce como consecuencia de una reacción inflamatoria exagerada mediada por los linfocitos del donante y estimulada por aquellos tejidos que han sido lesionados por la enfermedad de base, por las infecciones previas o por el tratamiento de acondicionamiento. El diagnóstico es clínico e histopatológico. Los pacientes presentan rash maculopapular pruriginoso y doloroso que puede extenderse por toda la superficie corporal, fiebre, vómito, náuseas, diarrea y anorexia. En la mucosa bucal se observan erosiones ulceradas, extremamente dolorosas y pueden ser la primera o la única manifestación detectable clínicamente de esta enfermedad. El objetivo es presentar un caso de enfermedad de injerto contra huésped. Se trata de una mujer de 54 años de edad con linfoma no-Hodgking, que recibió tratamiento con quimioterapia, radioterapia y trasplante de células madre hematopoyéticas en el 2009. Tres meses después, presentó lesiones en la piel diagnosticadas como enfermedad injerto contra huésped y tratadas con corticoesteroides, a los seis meses fue remitida al odontólogo porque se quejaba de ardor en la boca, xerostomía y dificultad para masticar, tenía úlceras en la mucosa bucal y en la lengua. En la ocasión recibió tratamiento con corticoesteroides, clorhexidina, orientaciones de higiene bucal y controles clínicos permanentes. Aunque existen protocolos para la prevención y el tratamiento de la enfermedad injerto contra el huésped, su frecuencia ha aumentado en los últimos años debido al incremento en el número de trasplantes. Por esta razón, es fundamental que el odontólogo forme parte del grupo multidisciplinario que asiste al paciente y que esté familiarizado con los signos y síntomas de esta enfermedad en la mucosa bucal, pues las manifestaciones clínicas pueden ser las únicas para

    We present a major update to ElecSus, a computer program and underlying model to calculate the electric susceptibility of an alkali-metal atomic vapour. Knowledge of the electric susceptibility of a medium is essential to predict its absorptive and dispersive properties. In this version we implement several changes which significantly extend the range of applications of ElecSus, the most important of which is support for non-axial magnetic fields (i.e. fields which are not aligned with the light propagation axis). Supporting this change requires a much more general approach to light propagation in the system, which we have now implemented. We exemplify many of these new applications by comparing ElecSus to experimental data. In addition, we have developed a graphical user interface front-end which makes the program much more accessible, and have improved on several other minor areas of the program structure.

    Full Text Available SUS440 is a high-carbon stainless steel, and its martensite matrix has high heat resistance, high corrosion resistance, and high pressure resistance. It has been widely used in mechanical parts and critical materials. However, the SUS440 martempered matrix has reliability problems in thin plate applications and thus research uses different austempering heat treatments (tempering temperature: 200 °C–400 °C to obtain a matrix containing bainite, retained austenite, martensite, and the M7C3 phase to investigate the relationships between the resulting microstructure and tensile mechanical properties. Experimental data showed that the austempering conditions of the specimen affected the volume fraction of phases and distribution of carbides. After austenitizing heat treatment (1080 °C for 30 min, the austempering of the SUS440 thin plates was carried out at a salt-bath temperature 300 °C for 120 min and water quenching was then used to obtain the bainite matrix with fine carbides, with the resulting material having a higher tensile fracture strength and average hardness (HRA 76 makes it suitable for use as a high-strength thin plate for industrial applications.

    2010-09-21

    SusG is an {alpha}-amylase and part of a large protein complex on the outer surface of the bacterial cell and plays a major role in carbohydrate acquisition by the animal gut microbiota. Presented here, the atomic structure of SusG has an unusual extended, bilobed structure composed of amylase at one end and an unprecedented internal carbohydrate-binding motif at the other. Structural studies further demonstrate that the carbohydrate-binding motif binds maltooligosaccharide distal to, and on the opposite side of, the amylase catalytic site. SusG has an additional starch-binding site on the amylase domain immediately adjacent to the active cleft. Mutagenesis analysis demonstrates that these two additional starch-binding sites appear to play a role in catabolism of insoluble starch. However, elimination of these sites has only a limited effect, suggesting that they may have a more important role in product exchange with other Sus components.

    Full Text Available Se presentan los resultados de una investigación dirigida a comprender los significados y las respuestas de madres frente al abuso sexual de sus hijas e hijos, para generar un conocimiento útil en la construcción de políticas y programas más pertinentes en la atención de este fenómeno. Es un estudio cualitativo que empleó como método los grupos de discusión con cinco madres de cuatro niñas y un niño, menores de 10 años, víctimas de abuso sexual, quienes asistían a consulta psicológica en dos centros de atención a la familia de la ciudad de Medellín, en el año 2005. Las voces de estas mujeres muestran que el abuso sexual sucede en familias vulnerables desde el punto de vista afectivo, comunicativo y socioeconómico, en las cuales este problema hace parte de su cotidianidad. El abuso sexual constituye una catástrofe que afecta el precario equilibrio socioeconómico y afectivo que estas familias logran construir para hacer frente a sus condiciones de vida angustiantes. En medio de la estigmatización que la sociedad hace de la situación, del silencio, con el cual soportan el trauma, y de un apoyo poco comprensivo y pertinente por parte de las instituciones encargadas de la atención de estas familias, las madres acometen diferentes acciones para hacer frente a su realidad. La reconfiguración de su rol como madres se convierte en un punto de partida clave para la superación del estado de impotencia en el cual quedan sumidas, posterior al abuso sexual de sus hijas(os.

    Full Text Available El artículo analiza la percepción que tiene una muestra representativa de la población española de entre 12 y 18 años sobre la protección de sus derechos en las cadenas de televisión. Para conseguir este objetivo, se aplicó un cuestionario de 59 preguntas diseñado para una investigación más amplia en la que se analizaba la opinión de los menores sobre la protección de sus derechos en la televisión y en Internet. Ninguna pregunta del cuestionario se refería a cadenas o programas concretos identificados por los investigadores y la información sobre estos partía de la propia opinión de los adolescentes. Los resultados que se presentan se refieren a los datos sobre televisión y, más concretamente, al respeto por los derechos fundamentales de los telespectadores en general, y de los de los menores en particular. De estos resultados se concluye que los adolescentes perciben claramente la vulneración de los derechos de igualdad, dignidad e intimidad, a la información objetiva veraz y plural y a la libre expresión y opinión –especialmente cuando ésta se refiere a los niños–. Igualmente muestran una postura crítica y de rechazo hacia los tipos de programas que no respetan sus derechos. Se propone utilizar esta capacidad crítica de los telespectadores desde una doble perspectiva: por una parte para crear escuela de ciudadanía y, por otra, para generar una sociedad más justa y equitativa.

Mattos também destaca a importância dos repasses federais entre os níveis de governos, por vê-los como instrumentos capazes de reduzir as desigualdades entre as regiões e incentivar políticas que contribuam para a consolidação do SUS. Na segunda parte, Nilson do Rosário afirma que o ajuste fiscal da década de 1990, conseqüência da política de estabilização monetária, limitou a capacidade de financiamento governamental na atenção à saúde, gerando efeitos perversos devido à ampliação da desigualdade social. A seguir, explica como o setor saúde respondeu às exigências de ajuste macroeconômico nas despesas públicas através de estratégias substitutivas, contexto em que o Programa de Saúde da Família (PSF se expandiu rapidamente, tornando-se estratégico na agenda da ampliação da atenção ambulatorial básica do país.This work discusses some of the issues related to the funding of the Brazilian National Health Service (SUS. In the first part of the paper, Ruben de Mattos advocates the creation of devices to guarantee a progressive increase in the public health budget. In the debater's view, the greatest challenge facing the government is the development - and the maintenance - of a system that can de facto guarantee universal and equalitarian access. Mattos also emphasizes the importance of the federal government's transfers of funds to local governments since the latter are seen as instrumental in the attempts to reduce inequality between regions and to encourage policies that will contribute to the SUS' consolidation.

    SUS 304 austenitic stainless steel causes the magnetic transition at 60 K, and the Young's modulus lowers. In addition, its composition elements have the large (n,α) reaction cross section to high energy neutrons, and helium is apt to be generated, and this is a factor that lowers the material strength. In the He-irradiated parts in austenitic stainless steel, the precursory state of martensite transformation should exist, and its effect is considered to be observable by carrying out low temperature Moessbauer spectroscopy. As to the preparation of He-irradiation samples, the SUS 304 foils used and the irradiation conditions are described. The measurement of low temperature Moessbauer spectra for the samples without irradiation and with irradiation is reported. In order to determine the magnetic transition point, the thermal scanning measurement was carried out for the samples without or with irradiation. The martensite transformation was measured by X-ray diffraction and transmission type Moessbauer spectroscopy. In order to observe the state of the sample surfaces, the measurement by internal conversion electron Moessbauer spectroscopy was performed. These results and the temperature dependence of the Moessbauer spectra for the irradiated parts are reported. (K.I.)

  10. Martensitic transformation behaviour in sensitized SUS304 austenitic stainless steel during isothermal holding at low temperature

    Lee, Jae-hwa; Fukuda, Takashi; Kakeshita, Tomoyuki

    2009-01-01

    We investigated martensitic transformation behaviour in sensitized SUS304 austenitic stainless steel to determine the stability of the austenitic phase at low temperatures. We found that a specimen that was sensitized at 973 K for 100 h exhibits an isothermal martensitic transformation when the specimen is held in the temperature range between 60 and 260 K. We constructed a time-temperature-transformation (TTT) diagram corresponding to the formation of 0.5 vol. % α'-martensite. A magnetization measurement was used to evaluate the volume fraction of a'-martensite. The TTT diagram shows a double-C curve with two noses located at about 100 and 200 K. In-situ optical microscope observations reveal that the double C-curve is due to two different transformation sequences. That is, the upper part of the C-curve is due to a direct γ → α' martensitic transformation and the lower part of the C-curve is due to a successive γ → ψ → α' martensitic transformation. The direct γ → α' transformation occurs in the vicinity of grain boundaries while the successive γ → ψ' → α' transformation occurs near the centre of grains. A scanning electron microscope observation reveals that carbide particles of M 23 C 6 are formed in the grain boundaries. The concentration difference between the centre of the grains and regions near grain boundaries is the reason for the difference in the isothermal transformation sequence for the sensitized SUS304 stainless steel.

  18. Experiencias de reconocimiento vividas por los niños en sus familias

    Full Text Available Pretendemos establecer una relación entre la propuesta que hace Axel Honneth sobre el reconocimiento en el amor y las prácticas de crianza vividas por los integrantes de la familia, en especial entre los niños y las personas cuidadoras, para argumentar que en estas relaciones se da comienzo a la configuración de los niños como sujetos políticos. Para Honneth –quien retoma a Hegel y a Mead–, las primeras relaciones amorosas son sustanciales para vivir el reconocimiento afectivo –que se vive con los más íntimos–; en ellas la aceptación emocional va unida a sentimientos como la simpatía y la atracción, y les permite visibilizar al otro a partir de sus necesidades propias y su valor humano. Abordaremos la familia como primera estructura de acogida y primer escenario de socialización, para argumentar que los niños viven en sus familias, prácticas de reconocimiento de sí mismos, de los otros y del mundo que les rodea, lo cual, a nuestro modo de ver, hace parte de su proceso de socialización como sujetos políticos.

    Full Text Available En noviembre de 1915, Unamuno celebró que hubiera surgido en España un interés por el examen filosófico de los problemas de la conciencia. Había asistido a «una conferencia sobre Filosofía de una serie tendiente a mostrar la diferencia entre la Psicología y la Lógica, que las da Ortega, y levanta el ánimo ver la cantidad y la calidad de los oyentes». No parece imposible que Unamuno hubiese escuchado parte del curso público de quince lecciones de psicología, dadas por Ortega en el otoño de 1915 y en el invierno de 1916. Curso cuyo texto incompleto había de salir publicado en 1982 con el título que le puso Paulino Garagorri, Investigaciones psicológicas. Garagorri reconocía la importancia del curso para aclarar la evolución filosófica de Ortega, pues en sus lecciones anunció su «superación del idealismo o subjetivismo». No sospechaba Garagorri, sin embargo, que el curso había de esclarecer además lo que entendía Ortega por el concepto de «superación ». Hasta ahora, la imposibilidad de saberlo ha hecho inciertas las relaciones de Ortega con sus fuentes idealistas.

    Full Text Available Abstract: In Brazil, ever since colonization plants have been used as natural products; thus, the National Health Surveillance Agency has been establishing rules for herbal medicine regulation; in this light, 71 plant species were chosen and empirically used in the country to investigate their medicinal properties. Currently, 12 of these 71 plants have been approved to be used in SUS (Public Health System, the remaining species still need further research. Thusly, this review aimed to seek information from toxicological studies on the plants that have not yet been officially approved, to stimulate new research in the field, promoting an economical and functional impact. In order to obtain the information, the keywords plant name + toxicity and/or toxicological studies were searched in the most prominent databases, both in English and in Portuguese. The ten plants with the most references were included in this review. Among the ten plants assessed, three have all the required studies required by the National Health Surveillance Agency, two of which we recommend the immediate adoption by SUS. In general, three plants have a determined LD50, nine have reproductive toxicity data, and five have not yet shown any sign of toxicity.

En su más amplio sentido, la Etnobotánica es el estudio de las relaciones que existen entre el hombre y su ambiente vegetal, es decir las plantas que lo rodean. En un sentido más restringido, se ha considerado solamente como el estudio del uso de las plantas cultivadas y silvestres por los pueblos primitivos, usualmente los aborígenes.

    Full Text Available Como agente reflexivo de su propia práctica, el profesorado construye creencias pedagógicas sobre el proceso de enseñanza y aprendizaje y, en particular, sobre el rol que sus estudiantes deben asumir en el aprendizaje de un idioma. Este estudio tiene como objetivo identificar las creencias pedagógicas de treinta docentes de inglés de primaria, secundaria y terciaria, en Chile, sobre el rol estudiantil en el proceso didáctico. Un cuestionario, una entrevista semi-estructurada, un diario auto-biográfico y cinco diarios de observación no-participante fueron utilizados para revelar las creencias pedagógicas de sus informantes. Los datos arrojados por los instrumentos fueron analizados con el programa cualitativo ATLASTI, que permitió el levantamiento de tres dimensiones y diez categorías, mediante el uso de la técnica del análisis de contenido semántico. Los resultados muestran que los tres grupos de profesorado declaran que estudiantes que aprenden una lengua extranjera deben tener características personales y académicas relacionadas con la motivación, la participación, la autonomía, entre otras; sin embargo, al interior del aula asumen un rol pasivo y reactivo frente al ambiente de enseñanza altamente estructurado que genera el personal docente. En conclusión, las creencias que cada docente sostiene se alimentan de la teoría y se corroboran o cuestionan en la práctica de aula, a modo de una relación bidireccional entre teoría y práctica, y viceversa.

    Das, A.K.; Ishigami, R.; Kamal, I.

    2015-01-01

    Microstructural damage and nano hardness of the industrial grade stainless steel (SUS-316) have been studied under proton (H + ) implanted condition applying different doses at room temperature. The implantation scheme such as proton energy, fluence, irradiation time, and penetration depth in the target materials were estimated by Monte Carlo Simulation Code SRIM-2008. In the simulation, the parameters were chosen in such a way that the damage density (displacement per atom or dpa) would be uniform up to certain depth from the surface. X-ray diffraction study of the annealed samples prior to the proton implantation showed the austenitic fcc structure and no significant change was observed after proton implantation in it. Microstructural observation made by Scanning Transmission Electron Microscopy (STEM) revealed that 1 dpa of proton-irradiation induced the structural damage extended up to 1 μm depth from the surface. The nano hardness study showed that the hardness level of the irradiated samples increased monotonically with the irradiation doses. Proton dose of 1 dpa caused 65% increment of hardness level on average in case of uniformly irradiated samples. It was realized that the increment of hardness was a consequence of microstructural damages caused by the formation of interstitial dislocation loops in the sample matrix keeping the lattice structure unaffected

  17. Results of fracture mechanics tests on PNC SUS 304 plate

    1985-08-01

    PNC provided SUS 304 plate to be irradiated in FFTF at about 400 0 C to a target fluence of 5 x 10 21 n/cm 2 (E > 0.1 MeV). The actual irradiation included two basically different exposure levels to assure that information would be available for the exposure of interest. After irradiation, tensile properties, fatigue-crack growth rates and J-integral fracture toughness response were determined. These same properties were also measured for the unirradiated material so radiation damage effects could be characterized. This report presents the results of this program. It is expected that these results would be applicable for detailed fracture analysis of reactor components. Recent advances in elastic-plastic fracture mechanics enable reasonably accurate predictions of failure conditions for flawed stainless steel components. Extensive research has focused on the development of J-integral-based engineering approach for assessing the load carrying capacity of low-strength, high-toughness structural materials. Furthermore, Kanninen, et al., have demonstrated that J-integral concepts can accurately predict the fracture response for full-scale cracked structures manufactured from Type 304 stainless steel

Se formularon matrices con registros biológicos y socioeconómicos obtenidos entre el 2009 y 2010 en temporadas de alto registro turístico, obteniendo 17 variables en 20 playas analizadas. La evaluación se efectuó con el modelo semiparamétrico del tipo KSIM con dos escenarios: uno sin control/restricción en el desarrollo costero y otro con las mismas características pero con decremento en demanda turística por baja calidad ambiental. Los resultados mostraron un marcado descenso en playas arenosas y costas rocosas. En el modelo se hace referencia a la importancia de los procesos de las playas y su interrelación con los factores biológicos, sociales y económicos más importantes, proporcionando una visión integral de todas las variables. Se recomienda incrementar el modelo dándole mayor envergadura, integrando a las instituciones que influyen en el control de las acciones en estas playas, lo que dará un mejor referente y monitoreo a corto, mediano y largo plazo.

    Full Text Available Este artigo discute a interlocução do sindicalismo brasileiro com o Sistema Único de Saúde (SUS e os planos e seguros privados de saúde. São ponderadas algumas teses na Saúde Coletiva à luz de estudos mais recentes nas Ciências Sociais sobre o sindicalismo e realizada análise documental para o caso da Central Única dos Trabalhadores (CUT, tomado aqui como referência. Aponta-se a necessidade de considerar os pesos relativos que a ação sindical atribuiu a cada um dos aspectos da relação, SUS e planos privados de saúde, pelas distintas conjunturas do país. O conflito entre trabalhadores e empresas somado ao desemprego e à precarização do trabalho expõe os limites das coberturas assistenciais privadas e impele a representação sindical a pleitear a intervenção estatal. O trabalho refletiu sobre as distintas modalidades de ação sindical na empresa e no Estado. A complexidade dessa dinâmica fez emergir um setor sindical interessado na gestão da previdência complementar e dos planos de saúde e, ao mesmo tempo, recria as circunstâncias e traz novas possibilidades de as organizações sindicais se colocarem na cena política e aglutinar os interesses de amplos segmentos dos trabalhadores para pressionar o Estado na defesa da melhoria do sistema público de saúde.The article intends to discuss the patterns of interlocution between the Brazilian trade unionism, the public health system (SUS and the private health insurance sector. Some thesis originated in the Public Health area about the subject are debated, in the light of more recent Social Science's studies concerned the Brazilian unionism. It presents a documentary analysis for the case of the largest National Workers Organization, named CUT. The need to discuss the problem in distinct political and economic conjunctures of the country is pointed out.

    Full Text Available Selective laser sintering (SLS is a type of laminating sintering technique, using CO2 laser with (metal, polymer, and ceramic powders. In this result, the flake SUS 316L was used to achieve a high porous product, and compare to spherical type. After SLS, the porosity of flake-type sample with 34% was quite higher than that of the spherical-type one that had only 11%. The surface roughness of the flake SLS sample were also investigated in both inner and surface parts. The results show that the deviation of the roughness of the surface part is about 64.40μm, while that of the internal one was about 117.65μm, which presents the containing of high porosity in the uneven surfaces. With the process using spherical powder, the sample was quite dense, however, some initial particles still remained as a result of less energy received at the beneath of the processing layer.

    Full Text Available El presente artículo analiza la crisis estructural del capitalismo provocada por el estallido de la burbuja especulativa inmobiliaria en EEUU en 2007 y sus repercusiones. El presente fenómeno es el desenlace de una serie de procesos desencadenados en respuesta a la crisis de sobreacumulación del capital de los años setenta que generó, por un lado, las condiciones para el dominio del capital financiero y, por otro lado, una nueva frontera de acumulación del capital en el Este asiático, sobre todo en China. La crisis cuestiona la centralidad de la economía norteamericana, lo que no significa necesariamente el desplazamiento del centro hegemónico del capitalismo hacia Asia. Lo que aquí defendemos, es la idea de que nos dirigimos hacia un mundo multipolar. This article analyzes the structural crisis of capitalism that began when the speculative home mortgage bubble burst in the United States in 2007, and the repercussions of that phenomenon. The current crisis is the outcome of a series of processes unleashed as a result of the crisis of overaccumulation of capital in the 1970s, which generated, on the one hand, the conditions for financial capital’s dominance and, on the other, a new frontier for the accumulation of capital in East Asia, especially in China. The crisis calls into question the centrality of the North American economy, but that does not necessarily mean the shift of capitalism’s hegemonic center to Asia. Here we will argue that we are headed toward a multipolar world.

    Full Text Available La violencia intrafamiliar constituye una de las formas más frecuentes de violencia encontradas tanto a nivel nacional como internacional y dentro de estas el maltrato infantil presenta cifras alarmantes, y es el objeto de nuestra revisión. Los efectos de este problema repercuten notablemente en aquellos que sobreviven, ya que las consecuencias a largo plazo del maltrato infantil son más perjudiciales para lasvíctimas y sus familias, y más costoso para la sociedad, que las lesiones agudas inmediatas que puedan producir. Las consecuencias a largo plazo para estos niños varían desde efectos nocivos en su desarrollo hasta trastornos psicológicos, psiquiátricos y orgánicos. Es importante resaltar que aún con muy buenas intervenciones no todas tienen el éxito esperado si no se hacen de manera correcta. Esindispensable contar con estrategias de prevención que incluyan personal bien entrenado, una supervisión adecuada, los recursos necesarios, y un tiempo mínimo óptimo para enfrentar el problema y obtener los mejores resultados. ______________________________________________________________________Domestic violence is one of the most common forms of violence found both domestically and internationally. Within these, child abuse has alarming figures. This is the subject of this review. The effects of this problem significantly impact on those who survive; their long-term consequences are most severe and expensive for victimized child and his/her family than associated primary physical injuries. Thelong-term consequences for these children range from adverse effects on its psycholigical development to psychological, psychiatric organic disoders. It is important to note that good speeches are not enough to achieve success if any intervention are not done correctly. All prevention strategies include well-trained staff, appropriate supervision, resources, and a optimal time for addressing this problem to get the best results.

    2013-12-01

    Full Text Available La determinación del cortisol sérico total forma parte fundamental de la exploración bioquímica de la función adrenocortical. Dado que esta hormona circula en plasma, en parte unida a proteínas de transporte y en parte en estado libre, existe la posibilidad de realizar la determinación de sus diferentes fracciones no solo en sangre sino también en orina, saliva y otros fluidos biológicos. Es posible realizar tanto determinaciones basales como pruebas funcionales y de esta manera evaluar la secreción de cortisol en un momento dado del día, estudiar su variación circadiana y analizar su relación con el resto de los componentes del eje hipotálamo-hipófiso-adrenal. Las mediciones habituales de cortisol en sangre, saliva y orina reflejan los niveles de esta hormona en el momento de la recolección o durante un período de 24 horas. Recientemente han aparecido trabajos en los cuales se propone la determinación de cortisol en cabello y uñas como potenciales marcadores del estatus hormonal en períodos más prolongados. El objetivo de esta revisión es realizar una puesta al día acerca de la metodología disponible actualmente en nuestro medio para la evaluación del eje adrenal, haciendo hincapié en su aplicación para el diagnóstico clínico.

    Pacheco, José Márcio da Cunha; Gomes, Romeu

    2016-08-01

    This paper analyses the decision making process for senior management in public hospitals that are a part of the National Health Service in Brazil (hereafter SUS) in relation to projects aimed at changing clinical management. The methodological design of this study is qualitative in nature taking a hermeneutics-dialectics perspective in terms of results. Hospital directors noted that clinical management projects changed the state of hospitals through: improving their organizations, mobilizing their staff in order to increase a sense of order and systemizing actions and available resources. Technical rationality was the principal basis used in the decision making process for managers. Due to the reality of many hospitals having fragmented organizations, this fact impeded the use of aspects related to rationality, such as economic and financial factors in the decision making process. The incremental model and general politics also play a role in this area. We concluded that the decision making process embraces a large array of factors including rational aspects such as the use of management techniques and the ability to analyze, interpret and summarize. It also incorporates subjective elements such as how to select values and dealing with people's working experiences. We recognized that management problems are wide in scope, ambiguous, complex and do not come with a lot of structure in practice.

    Full Text Available Este artículo aborda el impacto de la Gran Guerra en la ciudad de Rosario, Argentina. Releva sus impactos económicos y los significados que se les asignaron. Analiza las formas en que los actores sociales intentaron hacer frente a los efectos críticos del conflicto mundial: encarecimiento de los productos primarios, desabastecimiento y desocupación. En este campo resultan importantes la producción de ferias francas, la construcción de mercados municipales y el abasto directo de productos primarios por parte del municipio. Ante la dimensión y duración del paro, las autoridades comenzaron a tejer nuevas estrategias para intervenir sobre este fenómeno. Se observa una transición de unas estrategias gubernamentales basadas en la represión y la segregación a otras emparentadas con la asistencia y la ayuda social. Si bien estas nuevas herramientas de intervención no tendieron a perdurar y manifestaron su carácter coyuntural y paliativo, una vez superada la crisis, hacia mediados de los años 1920, organizaron el debate sobre la producción de nuevas políticas municipales y del reformismo local.

    Genomic differences between gut-resident bacterial strains likely underlie significant interindividual variation in microbiome function. Traditional methods of determining community composition, such as 16S rRNA gene amplicon sequencing, fail to capture this functional diversity. Metagenomic approaches are a significant step forward in identifying strain-level sequence variants; however, given the current paucity of biochemical information, they too are limited to mainly low-resolution and incomplete functional predictions. Using genomic, biochemical, and molecular approaches, we identified differences in the fructan utilization profiles of two closely related Bacteroides thetaiotaomicron strains. B. thetaiotaomicron 8736 ( Bt-8736 ) contains a fructan polysaccharide utilization locus (PUL) with a divergent susC / susD homolog gene pair that enables it to utilize inulin, differentiating this strain from other characterized Bt strains. Transfer of the distinct pair of susC / susD genes from Bt-8736 into the noninulin using type strain B. thetaiotaomicron VPI-5482 resulted in inulin use by the recipient strain, Bt ( 8736-2 ). The presence of the divergent susC / susD gene pair alone enabled the hybrid Bt ( 8736-2 ) strain to outcompete the wild-type strain in vivo in mice fed an inulin diet. Further, we discovered that the susC / susD homolog gene pair facilitated import of inulin into the periplasm without surface predigestion by an endo-acting enzyme, possibly due to the short average chain length of inulin compared to many other polysaccharides. Our data builds upon recent reports of dietary polysaccharide utilization mechanisms found in members of the Bacteroides genus and demonstrates how the acquisition of two genes can alter the functionality and success of a strain within the gut. IMPORTANCE Dietary polysaccharides play a dominant role in shaping the composition and functionality of our gut microbiota. Dietary interventions using these m icrobiota- a

    Thermo-mechanical treatment was given to improve further the superplastic behavior of SUS 304 stainless steel. In the SUS 304, martensite phase produced by the processing induced transformation may be reversely transformed to the primary austenite phase by high-temperature heating. Crystal grain size is micronized to 1 {mu} m by combining this reverse transformation and recrystallization of the austenite phase. However, the straining rate at that time is as extremely low as 1 times 10 {sup -4}/s or lower, which is insufficient for an industrial material. Therefore, the SUS 304 processed as described above was given again a series of thermo-mechanical treatment of the similar forced cold processing and annealing to ultra-micronize the crystalline particles. Majority of the crystalline particles have come to have a grain size of several hundred nm. This test piece showed a total elongation of 400% or more at a test temperature of 973 K and a straining rate of 1.8 times 10 {sup -3}/s or lower. In addition, the straining rate sensitivity index `m` at that time was 0.45 or higher. The superplastic deformation of the SUS 304 has a high possibility of being governed by dynamic recrystallization. 4 refs., 7 figs., 1 tab.

    Full Text Available Poznato je da se intenzivno teži smanjenju potrošnje goriva kod motora SUS pre svega iz ekoloških razloga. To se postiže primenom raznih konstrukcionih mera, medu kojima su i postupci koji doprinose smanjenju trenja. Da bi se postigao određeni uspeh na tom planu, neophodno je da se poznaju tribološke karakteristike motora u celini, kao i pojedinih sklopova i sistema. Najveći uticaj na trenje u motoru, a time i najveći interes za izučavanje triboloških karakteristika, izazivaju klipna grupa, ležaji kolenastog vratila, sistem razvoda i sistem za podmazivanje. Tribološke karakteristike motora treba poznavati još u fazi konstruisanja motora, jer jedino na taj način maze da se da puni doprinos smanjenju potrošnje goriva i izduvne emisije. / Intensive research for decreasing fuel consumption of IC engines is due wainly to ecologycal reasons. The problem can be solved by applying numerous diferent design solutions, among them methods for friction decrease. In order to achieve any success in that field it is necessary to be familiar with tribological features of a complete engine and its individual parts and assemblies. The main influence on IC engine friction losses comes from the piston group, the cranckshaft bearings, the timing system and the lubrication system. Tribological characteristics have to be determined in the first stage of IC engine design, because this is the only way to give full contribution to the decreasing of fuel consumption and exhaust emission.

    Full Text Available Desde hace largo tiempo, los indígenas de muchas regiones tropicales usan plantas venenosas para pescar, echándolas en agua durante ciertas épocas del año. El jugo de esas plantas se mezcla con el agua y paraliza los peces que, después de poco rato, suben aturdidos a la superficie, donde es fácil recogerlos. Tenemos conocimiento que tal procedimiento se ha usado en Asia Oriental, África del Sur y América tropical antes del descubrimiento de estas partes del mundo. En los países de habla española y portuguesa, las plantas venenosas para los peces son llamadas barbascos, término derivado de la palabra latina "verbascum", nombre de un género de la familia de las Escrofulariáceas, al cual pertenece el gordolobo, cuyas semillas se usaron en siglos pasados para entumecer los peces.

    Highlights: • Four SUS solutions are established to help reactors complete the start-up process. • Solutions C and D lead to superior behaved than Solutions A and B. • Solution C is fit for propulsion reactors and Solution D for nuclear power reactors. - Abstract: In this paper, we report on research that has been carried out both on the comparison and evaluation of four designed Start-up Systems (SUSs), which are proposed to improve reliability and economy during the reactor start-up process. Firstly, four SUS solutions are established to satisfy demands and detailed descriptions are introduced. Then, four reactor systems, which include SUS, are modeled by the estimate code JTopmeret. Furthermore besides, the JTopmeret code is validated for the once-through steam generators (OTSG). Finally, the behaviors of SUS and the steady and transient performance of OTSG are investigated. The results show that the designed SUS can successfully improve the economy and the OTSG operational safety. Suggestion is made in this paper to apply Solution C in propulsion-purposed reactors, and Solution D in nuclear power reactors

    Highlights: • The microstructure of F82H/SUS316L dissimilar joint can be divided into four regions. • In the case without beam position shift, hardness of WM cannot be reduced by PWHT. • The fiber laser welding would be applicable for constructing the dissimilar joint. -- Abstract: As one of the high beam quality heat sources, 4 kW fiber laser was applied for joining between reduced activation ferritic/martensitic steel, F82H and SUS316L austenitic stainless steel, and the microstructural analyses and Vickers hardness measurements were carried out before and after post-weld heat treatment (PWHT). The microstructure of joint can be divided into four regions which are base metal of F82H, heat affected zone (HAZ) in F82H, weld metal (WM) and base metal of SUS316L. Also, it is revealed that the high-power fiber laser can be employed for constructing butt joint between F82H and SUS316L by applying PWHT and shifting the laser beam position to SUS316L, where the distance between the contact face and beam should be set as a range from radius to diameter of laser beam.

    Full Text Available Sucrose transport is the central system for the allocation of carbon resources in vascular plants. Sucrose synthase, which reversibly catalyzes sucrose synthesis and cleavage, represents a key enzyme in the control of the flow of carbon into starch biosynthesis. In the present study the genomic identification and characterization of the Sus2-2A and Sus2-2B genes coding for sucrose synthase in durum wheat (cultivars Ciccio and Svevo is reported. The genes were analyzed for their expression in different tissues and at different seed maturation stages, in four tetraploid wheat genotypes (Svevo, Ciccio, Primadur and 5-BIL42. The activity of the encoded proteins was evaluated by specific activity assays on endosperm extracts and their structure established by modelling approaches. The combined results of SUS2 expression and activity levels were then considered in the light of their possible involvement in starch yield.

    Full Text Available El turismo es un importante sector estratégico para el crecimiento económico de Quintana Roo, ya que el 75% de su población está involucrada directa o indirectamente con la actividad. Asimismo, en Cozumel, la vida económica se desarrolla alrededor del turismo de cruceros y buceo por la calidad de sus recursos naturales submarinos. Sin embargo, la dependencia económica hacia un sector de la economía, provoca alteraciones en la estructura socioeconómica de las localidades, al verse afectadas por alguna contingencia de tipo ambiental o sanitaria; ejemplo de ello es el brote del virus de la influenza AH1N1 que afectó sensiblemente al sector turístico. En este sentido, el turismo y la salud son dos conceptos estrechamente relacionados, dado que ambos inciden directamente en la economía de los países y son parte de la política social (Chávez, 1994. En la zona del Caribe existe la amenaza de contraer dengue, enfermedad transmitida por el mosquito Aedes aegypti (vector; esta afección viral genera daños cuantiosos en la economía, en las actividades productivas y en el turismo (Zúñiga et al., 2009. Con base en lo anterior, el presente artículo pretende revelar el impacto del dengue en el sector turístico de Cozumel durante el año 2011.

    Highlights: • The role of oxide particles in α/α′ phase decomposition behavior; microstructure of phase decomposition observed by TEM. • The characteristics of ductility loss caused by age-hardening. • Correlation of phase decomposition and age-hardening explained by dispersion strengthened models. • Age-hardening susceptibility of ODS steels and SUS430 steel. - Abstract: The effect of aging on high-Cr ferritic steels was investigated with focusing on the role of oxide particles in α/α′ phase decomposition behavior. 12Cr-oxide dispersion strengthened (ODS) steel, 15Cr-ODS steel and commercial SUS430 steel were isothermally aged at 475 °C for up to 10,000 h. Thermal aging caused a larger hardening in SUS430 than 15Cr-ODS, while 12Cr-ODS showed almost no hardening. A characteristic of the ODS steels is that the hardening was not accompanied by the significant loss of ductility that was observed in SUS430 steel. After aging for 2000 h, SUS430 steel shows a larger ductile–brittle transition temperature (DBTT) shift than 15Cr-ODS steel, which suggests that the age-hardening susceptibility is lower in 15Cr-ODS steel than in conventional SUS430 steel. Thermal aging leaded to a large number of Cr-rich α′ precipitates, which were confirmed by transmission electron microscopy (TEM). Correlation of age-hardening and phase decomposition was interpreted by Orowan type strengthening model. Results indicate that oxide particles cannot only suppress ductility loss, but also may influence α/α′ phase decomposition kinetics.

    Surface oxide layer on SUS316L stainless steels exposed to 288degC pure water with 2 ppm dissolved oxygen (DO) for 1-100 h were analyzed using Focused Ion Beam (FIB) and Scanning Transmission Electron Microscope (STEM) technique to understand the early stage of surface oxide layer formation. In order to analyze the multi layered surface oxide, the interfaces between the outer and the inner oxide layers and that between the inner oxide layer and SUS316L substrate were determined from Energy Dispersive X-ray Spectroscopy (EDX) line profiles. At 1 h exposure, double oxide layer which is composed of compact inner oxide layer and outer oxide layer with Fe-rich and Ni-rich oxide particles was formed. At the outermost region of the SUS316L substrate, Ni and Cr were enriched. At 100 h exposure, growth of the inner oxide layer was suppressed and the Ni and Cr enriched region at the alloy substrate was preserved underneath the Ni-rich outer oxide particles. At 1 h exposure, most of the outer oxide particles were composed of Fe-rich ones, at 10 h exposure, another Ni-rich outer oxide particles were nucleated and grew faster than Fe-rich ones. Consequently, a part of pre-formed Fe-rich outer oxide particles were covered with Ni-rich ones. (author)

    Full Text Available El uso del video educativo como recurso didáctico ha permitido complementar el aprendizaje del estudiantado y apoyar el trabajo de los y las docentes. Si bien, en internet existen numerosos sitios especializados con videos educativos que pueden ser utilizados por los profesores y las profesoras en sus clases, la gran mayoría de estos recursos no han sido valorados por su principal público: estudiantes y docentes. El presente artículo describe la valoración que estudiantes de sexto año básico de la escuela pública David León Tapia, de la localidad de Tongoy en Chile, realizaron del video educativo “Benvoy y las hormigas”, que busca apoyar el aprendizaje del alumnado sobre los desastres naturales, sus causas, consecuencias y prevención. Para ello se solicitó a 27 alumnos y alumnas que contestaran una encuesta, luego de haber observado el video educativo dentro de su sala de clases, posteriormente se aplicaron entrevistas semiestructuradas a las docentes del curso. Se les consultó por preferencias de contenidos, tipos de recursos para el aprendizaje y relación con su entorno. Podemos concluir que la mayoría de los y las estudiantes que participaron en la encuesta indicaron que el video “Benvoy y las hormigas” les había ayudado a comprender los desastres naturales, calificándolo positivamente. Sobre los contenidos, los y las escolares mostraron preferencia por los capítulos sobre la prevención y normas de seguridad que se deben tomar ante desastres naturales y, en segundo lugar, las causas y consecuencias de los tsunamis. Las docentes, por su parte, destacaron la trama y la relación de los personajes con la vida cotidiana de los estudiantes.

    Full Text Available La Psicología Positiva ha sido objeto de ataques apasionados. Se ha cuestionado su novedad, su alcance científico, sus intenciones e incluso la honestidad de sus seguidores. Además, por extensión, se ha puesto en duda que la Psicología en su conjunto se ocupe de temas como el bienestar humano. En esta revisión ofrecemos una respuesta a algunas críticas desproporcionadas y efectuamos un repaso de la abrumadora evidencia existente derivada de la activa y sólida agenda de investigación que existe sobre las emociones y cogniciones positivas (p.ej.: optimismo y su relación con la salud y el bienestar psicológico. La Psicología no puede estar de espaldas a un movimiento general creciente, en las ciencias sociales y en el ámbito de la discusión política y económica, que sitúa el bienestar psicológico como un foco legítimo de atención. En esa dirección, la Psicología Positiva está contribuyendo, con los conceptos y herramientas propios de la Psicología, a articular y apoyar una buena parte de la investigación y promoción de esos temas cruciales. Finalmente se plantea que, en base a un diálogo académico veraz y respetuoso, la Psicología ineludiblemente deberá integrar fluidamente el enfoque sobre el funcionamiento positivo para poder explicar de un modo más integrador la naturaleza humana.

    Full Text Available Introduction: between 2000 to 2011, Diadema paulista municipality has faced many obstacles in health management, struggling to ensure the sustainability of its health system. Objective: to contribute to the discussion of the Unified Health System (SUS and its foreseable turbulent future, based on the analysis of the municipal point of view, identifying the limits of its building in Diadema. Methods: Diadema is characterized as one of the first municipalities that adhered to the principles of the SUS, since its implementation, allowing an analysis as a case study in view of the system's sustainability at the local level. The term sustainability used was addressed in two dimensions: the structure of this system and its process. Results: in SUS implementation period, Diadema stood out by increasing investment in health, reaching an average allocation of about 30% of its tax revenues, including constitutional transfers. Results diagnosed by observing the structure of dimensions and the process indicate that the sustainability of the municipal health system is threatened, as the significant expansion of the range of services and health actions was not followed by sufficient resources to its health maintenance. Conclusions: the existence of obstacles justified and formed the basis for the diagnosis of the main limits on SUS conformation, in health policy and management of resources, funding and budgetary impacts.

    Structural materials used in radiation environments require radiation tolerance and sufficient mechanical properties in the controlled state. In order to offer SUS316L austenitic stainless steel with the assumed requirements, nanostructured SUS316L with TiC addition of 2% (SUS316L-2TiC) that is capable of exhibiting enhanced tensile ductility and flow strength sufficient for structural applications was fabricated by advanced powder metallurgical methods. The methods include MA (Mechanical Alloying), HIP (Hot Isostatic Pressing), GSMM (Grain boundary Sliding Microstructural Modification) for ductility enhancement, cold rolling at temperatures below Md (the temperature where the martensite phase occurs by plastic deformation) for phase transformation from austenite to martensite and heat treatment for reverse transformation from martensite to austenite. It is shown that the developed SUS316L-2TiC exhibits ultrafine grains with sizes of 90-270 nm, accompanied by TiC precipitates with 20-50 nm in grain interior and 70-110 nm at grain boundaries, yield strengths of 1850 to 900 MPa, tensile strengths of 1920 to 1100 MPa and uniform elongations of 0.6-21%, respectively, depending on the heat treatment temperature after rolling at -196 °C.

    Full Text Available El propósito de este artículo es exponer diversos usos del síntoma en la cura analítica. Se tomará como hilo conductor el conjunto de las transformaciones del mismo en el curso del tratamiento. La cuestión general del síntoma y sus transformaciones está asociada a dos variables específicas: por un lado, a las intervenciones del analista, que promueven la modificación del estatuto del padecimiento; por otro lado, a las elecciones del ser hablante, quien, coyunturalmente, puede variar su posición subjetiva y su relación con el síntoma en el transcurso del tratamiento. Les emplois du symptôme : ses transformations au long de la cure Les divers emplois du symptôme dans la cure analytique sont exposés au long de cet article. C’est l’ensemble des transformations du symptôme au long de la cure qui permettra d’accomplir ce projet. La question générale du symptôme et de ses transformations sont liées à deux variables spécifiques : d’une part, les interventions de l’analyste, qui cherchent à modifier le statut de la souffrance ; de l’autre, les choix de l’être parlant qui, conjoncturellement, peut modifier sa position subjective, donc sa relation visà- vis du symptôme au cours du traitement. The symptoms’ uses: their transformations during the cure The purpose of this article is to present various uses of symptoms in analytic cures. The symptoms’ transformations throughout the course of psychoanalytic treatment will be examined. The general question regarding these symptoms and their transformations is associated with two specific variables: first, the analyst’s interventions, which promote change in the status of a patient’s suffering, and second, the choices of the speaking being, (parletre who can vary his subjective position and, therefore, his relationship with his symptoms during the course of treatment.

    Structural materials used in radiation environments require radiation tolerance and sufficient mechanical properties in the controlled state. In order to offer SUS316L austenitic stainless steel with the assumed requirements, nanostructured SUS316L with TiC addition of 2% (SUS316L-2TiC) that is capable of exhibiting enhanced tensile ductility and flow strength sufficient for structural applications was fabricated by advanced powder metallurgical methods. The methods include MA (Mechanical Alloying), HIP (Hot Isostatic Pressing), GSMM (Grain boundary Sliding Microstructural Modification) for ductility enhancement, cold rolling at temperatures below M_d (the temperature where the martensite phase occurs by plastic deformation) for phase transformation from austenite to martensite and heat treatment for reverse transformation from martensite to austenite. It is shown that the developed SUS316L-2TiC exhibits ultrafine grains with sizes of 90–270 nm, accompanied by TiC precipitates with 20–50 nm in grain interior and 70–110 nm at grain boundaries, yield strengths of 1850 to 900 MPa, tensile strengths of 1920 to 1100 MPa and uniform elongations of 0.6–21%, respectively, depending on the heat treatment temperature after rolling at −196 °C. - Highlights: • Nanostructured SUS316L-2%TiC exhibiting sufficient tensile ductility and strength is developed. • The development requires an advanced powder metallurgical route. • The route includes MA, HIP, GSMM and thermo-mechanical treatments for phase transformation. • The austenite grain sizes are 90–270 nm and TiC precipitates 20–50 nm in grain interior. • The tensile strength are 1100–1920 MPa and uniform elongation 0.6–21%.

  18. The insulin-like growth factor 2 (IGF2) gene intron3-g.3072G>A polymorphism is not the only Sus scrofa chromosome 2p mutation affecting meat production and carcass traits in pigs: evidence from the effects of a cathepsin D (CTSD) gene polymorphism.

    The objective of this study was to evaluate the effects of mutations in 2 genes [IGF2 and cathepsin D (CTSD)] that map on the telomeric end of the p arm of SSC2. In this region, an imprinted QTL affecting muscle mass and fat deposition was reported, and the IGF2 intron3-g.3072G>A substitution was identified as the causative mutation. In the same chromosome region, we assigned, by linkage mapping, the CTSD gene, a lysosomal proteinase, for which we previously identified an SNP in the 3'-untranslated region (AM933484, g.70G>A). We have already shown strong effects of this CTSD mutation on several production traits in Italian Large White pigs, suggesting a possible independent role of this marker in fatness and meat deposition in pigs. To evaluate this hypothesis, after having refined the map position of the CTSD gene by radiation hybrid mapping, we analyzed the IGF2 and the CTSD polymorphisms in 270 Italian Large White and 311 Italian Duroc pigs, for which EBV and random residuals from fixed models were calculated for several traits. Different association analyses were carried out to distinguish the effects of the 2 close markers. In the Italian Large White pigs, the results for IGF2 were highly significant for all traits when using either EBV or random residuals (e.g., using EBV: lean cuts, P = 2.2 x 10(-18); ADG, P = 2.6 x 10(-16); backfat thickness, P = 2.2 x 10(-9); feed:gain ratio, P = 2.3 x 10(-9); ham weight, P = 1.5 x 10(-6)). No effect was observed for meat quality traits. The IGF2 intron3-g.3072G>A mutation did not show any association in the Italian Duroc pigs, probably because of the small variability at this polymorphic site for this breed. However, a significant association was evident for the CTSD marker (P production traits in Italian Duroc pigs (lean content, ADG, backfat thickness, feed:gain ratio) after excluding possible confounding effects of the IGF2 mutation. The effects of the CTSD g.70G>A mutation were also confirmed in a subset of Italian Large White animals carrying the homozygous genotype IGF2 intron3-g.3072GG, and by haplotype analysis between the markers of the 2 considered genes in the complete data set. Overall, these results indicate that the IGF2 intron3-g.3072G>A mutation is not the only polymorphism affecting fatness and muscle deposition on SSC2p. Therefore, the CTSD g.70G>A polymorphism could be used to increase selection efficiency in marker-assisted selection programs that already use the IGF2 mutation. However, for practical applications, because the CTSD gene should not be imprinted (we obtained this information from expression analysis in adult skeletal muscle), the different modes of inheritance of the 2 genes have to be considered.

    2009-07-01

    Full Text Available El presente artículo, parte de mi tesis doctoral, aporta un singular estudio de la Alhambra elaborado desde la información obtenida de los libros de cuentas de las obras reales de este Real Sitio. Con el presente trabajo comprobaremos que este tipo de fuentes contienen valiosos datos para la Historia en general pero ante todo para la Historia Económica. En el caso concreto que abordamos, nos han servido para conocer cómo, cuando y donde se realizaron reparos, remodelaciones y nuevas construcciones en la Alhambra del siglo XVI, tema de vital importancia para la Historia del Arte de este monumento. Las obras reales de la Alhambra fueron iniciadas en la etapa de los Reyes Católicos, al día siguiente de la entrada en el recinto, cuando comprobaron el deterioro de esta bella ciudadela y fortaleza. Con el mismo ahínco y respeto fueron seguidas por su nieto Carlos V, quien sumó, al antiguo conjunto palaciego, la construcción del palacio imperial y su entorno urbanístico renacentistas. Finalmente, las obras fueron continuadas por Felipe II y sus sucesores los Austrias. Gracias al esfuerzo económico realizado por ellos, sobre todo durante el siglo XVI, hoy podemos contemplar la Alhambra. Ratifican lo dicho los Cargos y Datas de los libros de cuentas de Ceprián y Gaspar, fedatarios del volumen de las inversiones y de los considerables gastos realizados por la Real Hacienda castellana en las obras de la Alhambra1. Es valiosísima la aportación de los citados libros al respecto ya que recogen, detalladamente, los ingresos recibidos de cada una de esas consignaciones y su procedencia. Del mismo modo las datas nos proporcionan la cuantificación del gasto de las obras, pormenorizado por conceptos, en qué lugar del recinto se realizaron, qué materiales utilizaron y quiénes fueron sus proveedores –incluyendo curiosidades como la dificultad de la lejanía de canteras e incluso las particulares situaciones laborales de alguno de sus

Este artículo se interesa por una de las partes del binomio audiovisual, la banda sonora, con la finalidad de conocer su significado y sentido desde la propia interpretación infantil. Sus objetivos son determinar si los niños perciben de modo diferente los clips audiovisuales a los que son expuestos (sonido, imagen y todo; establecer las posibles diferencias en la valoración que realizan comparando las modalidades de presentación sonido e imagen. Se identificaron 14 audiovisuales preferidos (películas, series, dibujos animados y reportajes por parte de 115 niños de 10 a 12 años. Fueron editados en tres modalidades (solo sonido, solo imagen y todo y agrupados en series de tres clips, que fueron visionados en sesiones grupales por 547 niños, españoles y argentinos, con una edad media de 11 años. Se diseñó y utilizó un cuestionario de valoración de clips audiovisuales. Los resultados mostraron diferencias sobre el significado de la banda sonora en tres de las cinco categorías del cuestionario, destacando el predominio significativo del sonido en series, reportajes y, de manera destacada, en películas. Se perciben por el sonido (la música elementos contextuales espacio-tiempo, la implicación afectiva, sentimientos y empatía así como la valoración de la experiencia.

    The crystal structure of BT-3984, a SusD-family protein, reveals a TPR N-terminal region providing support for a loop-rich C-terminal subdomain and suggests possible interfaces involved in sus complex formation. The crystal structure of the Bacteroides thetaiotaomicron protein BT-3984 was determined to a resolution of 1.7 Å and was the first structure to be determined from the extensive SusD family of polysaccharide-binding proteins. SusD is an essential component of the sus operon that defines the paradigm for glycan utilization in dominant members of the human gut microbiota. Structural analysis of BT-3984 revealed an N-terminal region containing several tetratricopeptide repeats (TPRs), while the signature C-terminal region is less structured and contains extensive loop regions. Sequence and structure analysis of BT-3984 suggests the presence of binding interfaces for other proteins from the polysaccharide-utilization complex

    Full Text Available Este trabajo intenta visualizar en esta parte de América Latina el sufragismo y el feminismo, cuáles fueron sus aportes y sus puntos de mira. Es una interpretación otra, de las condiciones políticas que facilitaron una inserción parcial de las mujeres santiagueras a la consecución del voto. Se analiza como contribuyó la división de los partidos y su disputa por el control y el acceso al poder mediante estrategias y alianzas dudosas, cambiantes y temporales, además de considerarse por parte de la masculinidad hegemónica que la mujer no tenía una posibilidad real de comprender el momento político, el cual llevaba a la politiquería y a la corrupción. Ésto hizo también que las mujeres se mantuvieran de manera tangencial ante estos manejos. El voto de la mujer fue un simple juego de ajedrez de los partidos políticos, que consideraban ventajoso promover el sufragio femenino para obtener victoria ante estas luchas de poderes. No obstante, la mujer lo utilizó para sus fines, lograr derechos civiles y políticos y una participación más concreta en la sociedad con conciencia ciudadana, como sujetas de la historia, actoras y constructoras sociales al presionar para lograr sus demandas. Esta investigación también contribuye a un análisis sobre la situación de la mujer y su mentalidad, sus mecanismos sociales y las posibilidades de la transformación. Ha tocado la discriminación social y política. En este periodo, que abarca de 1902 a 1934, aunque la mujer haya logrado obtener derechos formales iguales, y a pesar de la no transformación radical de la condición de las mujeres, sí facilitó que un gran número de ellas tuviera acceso a la política y a la educación y sobre todo se percataron de la necesidad de autonomía en sus organizaciones.This work tries to visualize, in this part of Latin America, the suffragism and the feminism, what their contributions and their points of view were, and the way they were inserted in the

    The effect of Si content on the intergranular corrosion resistance of SUS 309L stainless steels was investigated by 10 wt.% oxalic acid test, 65 wt.% boiling nitric acid test, double loop electrochemical potential reactivation (DLEPR) method, optical microscope (OM) and scanning electronic microscope (SEM). A maximum corrosion rate, weight loss of 2.80 g m -1 h, was obtained when SUS 309L stainless steel containing 0.73 wt.% Si was subjected to heat treatment at 800 deg. C for 1 h. It shows that the Cr depletion zone formed due to σ phase precipitation. The same result is obtained in DLEPR test and the ditch microstructure after oxalic test was found in samples that showed the minimum corrosion rate

Por esta razón con el propósito de evaluar el comportamiento entre genotipos de jitomate F1 y F2, 37 híbridos y sus respectivas generaciones F2 fueron establecidos en invernadero. La mayoría de las generaciones F2 presentaron menor peso total de fruto por planta y número de frutos por planta con respecto a sus F1; sin embargo, el efecto fue estadísticamente significativo sólo en dos genotipos tipo bola de hábito de crecimiento determinado y cuatro genotipos tipo bola de hábito de crecimiento indeterminado, los cuales abatieron su producción de fruto de F2 en al menos 20 %

    This review focuses only on specific studies into the SUS regionalization process, which were based on empirical results and published since 2006, when the SUS was already under the aegis of the Pact for Health framework. It was found that the regionalization process is now underway in all spheres of government, subject to a set of challenges common to the different realities of the country. These include, primarily, that committee-structured entities are valued as spaces for innovation, yet also strive to overcome the bureaucratic and clientelist political culture. Regional governance is further hampered by the fragmentation of the system and, in particular, by the historical deficiency in planning, from the local level to the strategic policies for technology incorporation. The analyses enabled the identification of a culture of broad privilege for political negotiation, to the detriment of planning, as one of the main factors responsible for a vicious circle that sustains technical deficiency in management.

    Full Text Available En el presente trabajo nos detenemos en la relación alma-cuerpo en el contexto del Avicenna latinus, prestando especial atención a la definición de alma y a la diversificación de sus funciones en su relación con el cuerpo. Así, en la primera parte analizamos el dictamen de alma del pensador árabe en tanto y en cuanto nos la permita considerar -como bien Avicena lo hace remitiéndose a Aristóteles- elemento común a todos los niveles de vida; no a la manera de una realidad no-accidental añadida a un cuerpo constituido orgánicamente, sino como principio de organización del mismo, de sus funciones o potencias. Luego, exponemos la división y clasificación de las facultades y de las actividades del alma, gracias a las cuales podemos establecer un marco epistemológico que explique precisamente en parte lo que entiende por abstracción.

  1. Biochemical and Molecular Characterization of RcSUS1, a Cytosolic Sucrose Synthase Phosphorylated in Vivo at Serine 11 in Developing Castor Oil Seeds*

    Sucrose synthase (SUS) catalyzes the UDP-dependent cleavage of sucrose into UDP-glucose and fructose and has become an important target for improving seed crops via metabolic engineering. A UDP-specific SUS homotetramer composed of 93-kDa subunits was purified to homogeneity from the triacylglyceride-rich endosperm of developing castor oil seeds (COS) and identified as RcSUS1 by mass spectrometry. RcSUS1 transcripts peaked during early development, whereas levels of SUS activity and immunoreactive 93-kDa SUS polypeptides maximized during mid-development, becoming undetectable in fully mature COS. The cytosolic location of the enzyme was established following transient expression of RcSUS1-enhanced YFP in tobacco suspension cells and fluorescence microscopy. Immunological studies using anti-phosphosite-specific antibodies revealed dynamic and high stoichiometric in vivo phosphorylation of RcSUS1 at its conserved Ser-11 residue during COS development. Incorporation of 32Pi from [γ-32P]ATP into a RcSUS1 peptide substrate, alongside a phosphosite-specific ELISA assay, established the presence of calcium-dependent RcSUS1 (Ser-11) kinase activity. Approximately 10% of RcSUS1 was associated with COS microsomal membranes and was hypophosphorylated relative to the remainder of RcSUS1 that partitioned into the soluble, cytosolic fraction. Elimination of sucrose supply caused by excision of intact pods of developing COS abolished RcSUS1 transcription while triggering the progressive dephosphorylation of RcSUS1 in planta. This did not influence the proportion of RcSUS1 associated with microsomal membranes but instead correlated with a subsequent marked decline in SUS activity and immunoreactive RcSUS1 polypeptides. Phosphorylation at Ser-11 appears to protect RcSUS1 from proteolysis, rather than influence its kinetic properties or partitioning between the soluble cytosol and microsomal membranes. PMID:25313400

    The behavior of martensitic transformation due to plastic deformation at room temperature was investigated in SUS304 austenitic stainless steels with the same nickel equivalent. The absolute volume of the martensitic phase was obtained by saturation magnetization. We discuss the shapes of the martensitic phase caused by different values of coercive force. Martensitic transformation depends on the applied stress but is independent of nickel content with same nickel equivalent. We investigated applications to nondestructive testing on the basis of the present study. (author)

C for up to 100 h was conducted. Optical microscopy reveals grain coarsening in both the alloys upon annealing. Observations by transmission electron microscopy revealed the precipitation of nanometer-sized spherical Cu particles distributed within the austenitic grains and the presence of carbides at the dislocations. Both the yield and ultimate tensile strengths of the alloys were found to remain invariant with annealing. Tensile ductility and the threshold stress intensity factor range for fatigue crack growth for 3 wt.% Cu added alloy increase with annealing. These are attributed to the grain coarsening with annealing. In all, the addition of Cu to SUS 304H does not affect the mechanical performance adversely while improving creep resistance.

  9. Healthcare regions and their care networks: an organizational-systemic model for SUS.

    Science.gov (United States)

    Santos, Lenir

    2017-04-01

    This paper describes a comprehensive effort to develop studies regarding Brazil's Unified Healthcare System (SUS), as a result of the combination of public services in a network that follows a region-based rationale (tripartite organization). The SUS emerges from such an integration and should be organized as such. The intention is to demonstrate that this type of organization is essential, given that Brazil is organized as a Federation, and all three governmental levels are, in a broad sense, equally responsible for healthcare. Healthcare services and actions are a complex set of activities that are interconnected on behalf of citizen health, which is a global concept that cannot be split up. Services must follow this rationale and be organized as such. Thus, healthcare services must be systematically organized to serve everyone equally, regardless of where a citizen lives. This systemic organization requires permanent interaction between federative units to discuss and operationalize reference services, funding and other technical and administrative aspects. These are the essential elements that make the SUS so complex and demand it be organized regionally, as a network of healthcare services.

En palabras de Roberto Matta (1965: La función del artista en nuestra sociedad consiste en ser este personaje deslumbrador y repudiado, como el niño del cuento de Andersen, que es el único que dice que el rey va desnudo. Esta situación de denuncia del escándalo hace de él un minoritario. No se trata, pues, para el artista, de establecer un relación entre un azul y un verde: estos cuadros estéticos son más o menos poseídos por aquellos que los contemplan. Yo quiero, al contrario, inquietar, para que el que contempla se convierta en minoritario. Deseo que este espectador, en lugar de poseer el cuadro, sea poseído por él, que sea bombardeado por una enorme cantidad de conciencia que le llegue de todas partes. Así, atrapado en una situación insoportable a causa de esta pintura, se ve obligado, también él, a realizar un acto poético de creación para hacerla suya: asediado por lo real, se siente vencido y, por tanto, reflexiona.

    2012-04-23

    Globalisation, in terms of the rapid and free movement of people, animals and food, has created a new paradigm, increasing the range and rate of distribution of many pathogens. In the present study, Torque teno sus viruses (TTSuVs) have been used as a model to evaluate the effects of global trade on viral heterogeneity, and how the movement of live pigs can affect the distribution and composition of virus populations. Seventeen countries from different parts of the world have been screened for TTSuV1 and TTSuvV2. High levels of genetic diversity have been found as well as two new TTSuV subtypes. A small fraction of this diversity (50%) was best explained by the exchange of live pigs among countries, pointing to the direct relationship between the movement of hosts and the diversity of their accompanying viruses. Taking TTSuVs as sentinels, this study revealed that the distribution and diversity of comensal microflora in live animals subjected to global trade is shaped by the commercial movements among countries. In the case of TTSuVs, it appears that commercial movements of animals are eroding the genetic composition of the virus populations that may have been present in pig herds since their domestication.

    Full Text Available Se analiza la crisis financiera internacional presente, nacida en el mercado hipotecario norteamericano, claramente identificable a partir de agosto de 2007. Las bolsas de valores entre ese momento y los primeros días de diciembre de 2008 mostraron significativas caídas en los principales papeles que se comercian en los distintos lugares del mundo y la elevada volatilidad de las cotizaciones caracterizó su performance. Al momento de escribir este artículo, las mejoras bursátiles llevan dos semanas consecutivas, lo que parece una respuesta a la importante tarea de salvatajes coordinados por parte de los países más avanzados del mundo en los últimos 90 días. La crisis ha sido tan intensa que hace que muchos analistas la comparen con la surgida luego del crac bursátil de octubre de 1929. Se teme que le siga, como en aquella época, un período de un año o dos años de fuerte recesión económica, cuando no de depresión. El escrito muestra, en el primer apartado, el sistema financiero y sus componentes a los fines de localizar el núcleo de la crisis. En el segundo detalla cómo esta crisis originada en los intermediarios financieros propiamente dichos –bien distinta a lo que es una crisis bancaria tradicional– puede llegar a afectar a los bancos y potencialmente al sistema monetario. En el tercer apartado, señala los elementos concurrentes que dieron lugar a la crisis actual, que son: la política de tasa de interés seguida por la Reserva Federal de EE.UU. a partir del año 2001, el relajamiento de los estándares sobre las condiciones económicas del deudor para hacerse del crédito –sobre todo del crédito inmobiliario–, y la falta de una adecuada regulación de las “finanzas estructuradas”. Estos elementos, en conjunción, permitieron potenciar el ratio de deuda sobre el patrimonio neto de los intermediarios financieros propiamente dichos y la aparición de problemas de riesgo moral, generándose burbujas especulativas

    2012-10-01

    The primary objective of this study was to determine genetic and genomic parameters among swine (Sus scrofa) farrowing traits. Genetic parameters were obtained using MTDFREML. Genomic parameters were obtained using GENSEL. Genetic and residual variances obtained from MTDFREML were used as priors for the Bayes C analysis of GENSEL. Farrowing traits included total number born (TNB), number born alive (NBA), number born dead (NBD), number stillborn (NSB), number of mummies (MUM), litter birth weight (LBW), and average piglet birth weight (ABW). Statistically significant heritabilities included TNB (0.09, P = 0.048), NBA (0.09, P = 0.041), LBW (0.20, P = 0.002), and ABW (0.26, P NBA (0.97, P NBA-LBW (0.56, P NBA (0.06), NBD (0.00), NSB (0.01), MUM (0.00), LBW (0.11), and ABW (0.31). Limited information is available in the literature about genomic parameters. Only the GP estimate for NSB is significantly lower than what has been published. The GP estimate for ABW is greater than the estimate for heritability found in this study. Other traits with significant heritability had GP estimates half the value of heritability. This research indicates that significant genetic markers will be found for TNB, NBA, LBW, and ABW that will have either immediate use in industry or provide a roadmap to further research with fine mapping or sequencing of areas of significance. Furthermore, these results indicate that genomic selection implemented at an early age would have similar annual progress as traditional selection, and could be incorporated along with traditional selection procedures to improve genetic progress of litter traits.

Para ello se les administró las versiones españolas del SAS-2 (Sport Anxiety Scale-2, Smith, Smoll, Cumming y Grossbard, 2006 y el MCSYS (Motivational Climate Scale for Youth Sports, Smith, Cumming y Smoll, 2008, así como dos escalas ad hoc para evaluar la percepción de su habilidad y rendimiento. Los resultados muestran, por una parte, que los jóvenes futbolistas perciben y discriminan claramente los climas motivacionales, que se distribuyen casi al 50% entre ego y maestría, por otra, que aparece ansiedad competitiva, aunque más cognitiva que somática, y que no existe relación significativa con las percepciones de habilidad y rendimiento por parte de los entrenadores. Finalmente, estos resultados se discuten y se comparan con otros similares en poblaciones preadolescentes.

    Full Text Available Objetivo. El propósito de este estudio fue evaluar el efecto educativo del Plan de Salud Oral Integral de la Embarazada, aplicado desde el año 2010 en Chile, sobre la salud oral de sus hijos a los dos años de edad en el centro de salud familiar (CESFAM de la municipalidad de Lo Barnechea. Materiales y Métodos. Estudio descriptivo, observacional y transversal. Se analizó la información de 129 niños que acudieron a su primera atención dental. Se determinó la presencia de malos hábitos, presencia de caries y nivel de riesgo cariogénico. La muestra se analizó según las variables independientes: madres que contaban con el Alta del Plan de Salud Oral Integral de la Embarazada y madres que no fueron parte del plan. Además dentro del grupo de madres que contaban con el Alta del Plan de Salud Oral Integral de la Embarazada un grupo acudió a un Control Binomio madre e hijo a los 6 meses de edad del menor. Resultados. No existen diferencias significativas en presencia de caries ni en malos hábitos entre los grupos en estudio. La presencia de 'Alta del plan de Salud Oral Integral de la Embarazada' se asocia de manera altamente significativa (p<0,005 a un menor consumo de alimentos con azúcar al día. La presencia de 'Alta del plan de Salud Oral Integral más un Control Binomio' también se asocia a un menor consumo de alimentos con azúcar al día (p<0,05 y a pacientes con riesgo cariogénico bajo (p<0,005. Conclusión. En la mayoría de las variables estudiadas no se encontraron diferencias significativas entre los grupos estudiados, lo que demuestra que el Plan de Salud oral Integral de la Embarazada aplicado en CESFAM de la Municipalidad de Lo Barnechea no tiene el efecto esperado de mejorar la salud oral de sus hijos a los 2 años de edad

    Full Text Available Jorge Isaacs es conocido por María (1867, novela cumbre del romanticismo americano. Pero Isaacs, además, fue un político liberal radical que llevó adelante una revolución, en enero de 1880, movido por sus principios ideológicos en medio de lo que él consideraba la traición de los liberales. La revolución, embebida de romanticismo, fue una empresa romántica destinada al fracaso desde un principio. Este artículo, a partir del estudio de los documentos de la época, analiza de qué manera Isaacs desarrolló sus actividades militantes, como superintendente de Educación, primero, como congresista, después, y como revolucionario, en el marco del proceso de recuperación del poder por parte de los conservadores. Asimismo, este artículo se enfoca en el espíritu romántico que animó a Isaacs y cómo se expresó a través de la palabra encendida de los manifiestos, proclamas, cartas e informes recopilados por el propio Isaacs en su libro La revolución radical en Antioquia (1880.   Jorge Isaacs is well-known for Maria (1867, which is considered the most important novel of Latin American romanticism. But Isaacs was also a radical liberal politician who carried forward a revolution, in January 1880, moved by his ideological principles in the midst of what he considered to be the treason of the liberals. From the very beginning, this revolution, which was immersed in romanticism, was an enterprise destined to fail. This article, based on the study of documents from that time, analyzes the way in which Isaacs developed his militant activities firstly as an Education inspector, then as a congressman, and finally as a revolutionary in the framework of the recovery process by the conservative party. Likewise, this article focuses on the romantic spirit that inspired Isaacs and how he expressed himself through his passionate words present in manifestos, proclamations, letters, and reports compiled by Isaacs himself in The Radical Revolution in

    Full Text Available El propósito de este artículo es analizar procesos de formación asociados a la capacidad para desarrollar investigación, innovación educativa, espacios de liderazgo y comunicación interna, y vinculación escuela-familia en establecimientos educacionales de Chile. La muestra se constituyó de 108 docentes de pre-escolar, educación básica y media, pertenecientes a establecimientos públicos, semi-públicos y particulares de la Región del Biobio en Chile. La investigación es de tipo cuantitativo transeccional, con un diseño de carácter correlacional. Para recolectar la información se utilizó la técnica de la encuesta y el análisis de datos se realizó mediante conglomerados jerárquicos. Los resultados muestran que los profesores encuestados no consideran que la investigación sea parte de sus prácticas docentes. A pesar de que gran parte de los docentes reconocen realizar innovaciones, son percibidas como una instancia aislada, desvincula das del liderazgo directivo. Los hallazgos además indican que los docentes ejercen liderazgo a nivel pedagógico y directivo. La comunicación interna es valorada positivamente por los docentes, sin embargo, la vinculación entre escuela y familia es débil. A nivel de formación continua, los docentes consideran que las instancias de perfeccionamiento no promueven el desarrollo personal.

Dentro do programa de Humanização implantado na Maternidade de Londrina pretendeu-se analisar o atendimento a parturiente quanto à humanização ao partocomparando com a realidade de dois hospitais de Guarapuava onde não existe o programa implantado e assim verificar se os direitos destas parturientes quanto à humanização estão sendo respeitados. Foi aplicado um questionário a 40 primíparas no puerpério imediato comperguntas semi-estruturadas. Ao comparar duas realidades diferentes, concluiu-se que alguns dos direitos das parturientes preconizados pela OMS não estavam sendo respeitados, especialmente onde não havia a implantação do parto humanizado, pois não era permitida a entrada de acompanhante e nem utilizadas técnicas de relaxamento para a parturiente, evidenciando assim que algumas instituições necessitam intensificar esses cuidados para melhorar a qualidade do atendimento prestado.This descriptive study was conducted in maternities assisted by the Brazilian Health System (SUS, in the cities of Guarapuava and Londrina, State of Paraná. In the program implanted in Londrina, the aim was to analyze the assistance to the parturient regarding humanization to the child delivery. This context was then comparedwith the reality in the maternities of two hospitals in Guarapuava, where these practices are not applied. The comparison intended to verify if the rights of these women to humanized delivery are being respected. A half-structured questionnaire was applied to forty women in labor. While comparing these two different realities, it was observed that a few of these rights, advocated by the OMS, were not being respected, especially where the humanization delivery was not a practice.

    This study sought to develop methodology for the construction of a Panel for the Monitoring and Evaluation of Management of the Unified Health System (SUS). The participative process used in addition to the systematization conducted made it possible to identify an effective strategy for building management tools in partnership with researchers, academic institutions and managers of the SUS. The final systematization of the Panel selected indicators for the management of the SUS in terms of Demand, Inputs, Processes, Outputs and Outcomes in order to provide a simple, versatile and useful tool for evaluation at any level of management and more transparent and easier communication with all stakeholders in decision-making. Taking the management of the SUS as the scope of these processes and practices in all normative aspects enabled dialog between systemic theories and those which consider the centrality of the social actor in the decision-making process.

    Full Text Available Abstract Background: This study was motivated by the need of understanding how the relationship of the training with the national health system is treated, both in the sphere of health services and the aca-demic area. This work aims to contribute to the debate on the inclusion of the physiotherapist in SUS (Brazil's NHS by pointing out issues that need to be deepened in future studies. Purpose: To analyze the national literature production on the relationship between the training of therapists and their work in SUS, from 1996 to 2010. Methods: Descriptive research with literature on the bases: LILACS, SCI-ELO Bank and CAPES thesis. Results: We found 13 publications, sorted by: year, publication type, region where it was published in the categories "national curriculum guidelines," "professional respon-sibility", "integrality in health" and "conceptions of teachers in training in Physiotherapy ". There no publishing from 1996 to 2005, gradually increasing from this year. It was identified a higher number of articles compared to other types of publications; there is also an important difference between the Brazilian regions, with higher prevalence of studies in the South (53.8% and a greater number of pub-lications in the category "national curriculum guidelines". Conclusion: It was possible to raise ques-tions that involve the applicability of the National Curriculum Guidelines on the pedagogical courses; suitability of teachers to the reality of SUS; investigation of the models covered in health care envi-ronments trainers, and the lack of contribution by higher education institutions on teaching-research and teaching and public service, contributing to form an important agenda of study. {#}

  13. The precipitation behavior of titanium carbide on the surface of SUS 321 stainless steel

    International Nuclear Information System (INIS)

    Yoshihara, Kazuhiro; Nii, Kazuyoshi

    1982-01-01

    The surface composition of SUS 321 stainless steel at high temperatures was observed in vacuum with Auger electron spectroscopy. The precipitation of titanium carbide was found on the surface of SUS 321. The thickness of precipitated titanium carbide layer increased in proportion to the square root of annealing time and became about 0.05 μm after heated at 1100 K for 432 ks. The precipitated titanium carbide was not replaced by the most surface active element sulfur, and remained stable on the surface. The precipitated layer, however, was not even and had many holes about 1 μm in diameter. The bottom of a hole was SUS 321, on which phosphorus, oxygen and sulfur segregated. As the annealing time was prolonged, these segregants were replaced one by one in the order of the surface activity, and finally the most surface active element, sulfur, remained on the bottom of the hole. Moreover, sulfur diffused over the outside of the hole. The precipitation of titanium carbide on the surface occurred according to the following processes: (1) The titanium and carbon which had been dissolved in the bulk diffused onto the surface of the stainless steel. (2) The titanium carbide which had been precipitated in the bulk dissolved because the concentration of titanum and carbon fell under their solubility limits in the bulk. (3) The titanium and carbon diffused onto the surface which was exposed to vacuum. (4) The titanium and carbon recombined into titanium carbide and precipitated on the surface. The growth rate of the thickness of the precipitated layer was controlled by the diffusion of titanium and carbon in the precipitated titanium carbide. (J.P.N.)

El propósito de esta investigación fue describir las teorías de la cefalogénesis y sus malformaciones craneofaciales, como requisito para proponerteorías integradoras que favorezcan su mejor comprensión. Se realizó una revisión biobliográfica sobre el tema de la cefalogénesis y las concepciones científicas actuales concernientes a las teorías de las malformaciones congénitas craneofaciales. Se realizó una revisión en Internet, en el periodo comprendido entre diciembre de 2011 y enero de 2012. Se analizaron los artículos de revistas de la Web of Sciences que trataron este tema desde el año 2006 hasta el 2012 en los buscadores Google academico, Hinari, Scopus, Scielo y Medline. Como resultado se obtuvieron 131 artículos que fueron tamizados; pero el estudio se ciñó solo a 43 artículos que enfocaron estas temáticas de manera más integral. Se consideraron reduccionitas o incompletas las teorías hasta ahora expuestas. Por tal motivo se propusieron teorías holístico-sinérgicas de la cefalogénesis y sus malformaciones.

    Full Text Available O presente artigo desenvolve o tema da necessidade de se regionalizar a descentralização no sentido de aglutinar o que esta supostamente poderia ter fracionado. Ao revisitar a diretriz constitucional da descentralização os autores propõem medidas que visem sua garantia ao lado de ferramentas administrativas que permitam a formação de regiões de saúde resolutivas em pelo menos 95% das necessidades de saúde do território regional, para garantir autonomia sanitária. Os autores propõem soluções que passam pela criação de pessoas jurídicas associativas regionais, resultantes da aglutinação dos entes federativos em região de saúde. Apontam ainda o que não deu certo no Sistema Único de Saúde - SUS Brasil em razão tanto de equívocos originados nas melhores intenções, quanto do oportunismo que esses equívocos geraram. Advogam os autores a necessidade de respostas jurídico-administrativas para um SUS de caráter interfederativo tanto na sua gestão, que exige compartilhamentos, quanto no seu financiamento, que se mantém interdependente também. Concluem que o único caminho para o SUS ser nacional, é regionalizá-lo e dotar a região de saúde de todo o instrumental necessário à gestão compartilhada, interfederativa e responsável.

    Full Text Available La inseguridad laboral se ha convertido en la actualidad en una de las fuentes de estrés más significativas para muchos trabajadores, siendo especialmente grave en España por las elevadas tasas de desempleo en este periodo de crisis económica. Una prolífera investigación se ha desarrollado al respecto en un intento por alcanzar un conocimiento más completo de este fenómeno. El Instituto de Psicología de los Recursos Humanos, Desarrollo Organizacional y Calidad de Vida Laboral (IDOCAL ha contribuido a esta investigación en los últimos años en varias de sus facetas más significativas. En el ámbito de sus factores determinantes se ha identificado un papel significativo de la antigüedad laboral, la empleabilidad en el mercado laboral, el subempleo, y la autoeficacia laboral. Además se han realizado hallazgos de interés en relación con la diversidad de los tipos de contrato, la inseguridad laboral y sus efectos en los trabajadores. Son de especial interés los estudios que analizan el papel interviniente de distintas variables. En este contexto, nuestros estudios han puesto de manifiesto la relevancia de variables como la justicia organizacional, el clima de justicia organizacional, el apoyo organizacional, la empleabilidad, la dependencia laboral y el distanciamiento psicológico a la hora de predecir la variabilidad en la inseguridad laboral. Por último, las aportaciones del IDOCAL han sido especialmente relevantes al plantear el análisis de la inseguridad laboral como fenómeno colectivo y mostrar cómo la experiencia colectiva de la inseguridad tenía repercusiones sobre el bienestar de los trabajadores más allá de las producidas por sus percepciones individuales. En base a esta investigación se han propuesto en el presente artículo una serie de implicaciones para la práctica profesional.

    Full Text Available La mercadotecnia política se incorporó a los procesos electorales de América Latina a finales de los años 1980s como parte del proceso de transición hacia la democracia. A partir de esta incorporación, se ha generado un fuerte debate entre sus impulsores y sus detractores sobre su uso, potencialidades, contribuciones y riesgos que representa para el sistema democrático. En lo particular, tres han sido los cuestionamientos más importantes que se han hecho a esta disciplina: primero, sobre su alejamiento de los principios áticos. Segundo, sobre su relación adversa a los sistemas democráticos y tercero, sobre el carácter acientífico de la disciplina En el presente ensayo, se analizan estos cuestionamientos, a la luz de las formulaciones teóricas más sobresalientes de los últimos años, concluyendo que la mercadotecnia es una ciencia social, sin intencionalidad propia, que ayuda al mejor entendimiento de los procesos de intercambio político voluntario que se dan en toda sociedad democrática.

    Full Text Available Este artigo analisa o grau de progressividade dos tributos que financiam o Sistema Único de Saúde (SUS. Nele são identificados os principais tributos que financiam o SUS e, com base nos microdados da Pesquisa de Orçamentos Familiares 2002-2003, é inferida a distribuição do ônus do pagamento dos tributos diretos e indiretos que financiam o SUS e analisado o grau de progressividade dos mesmos. Foi, ainda, calculado o índice de Kakwani do financiamento do SUS, que sintetiza o grau de progressividade de um sistema tributário. Os dados mostraram que o índice de Kakwani do financiamento público é de ­0,008 e que, portanto, o financiamento do SUS corresponde a um sistema quase proporcional, que onera proporcionalmente à renda. Em uma sociedade com o grau de desigualdade da brasileira, que exibe um índice de Gini de 0,57, ter um financiamento do SUS proporcional é fortemente questionável sob a ótica da justiça social: ao contrário, seria desejável construir bases de financiamento do SUS francamente progressivas, de forma a contra-restar a fortíssima concentração de renda da nossa sociedade.This article analyzes the level of progressivity in taxes financing the Brazilian Unified National Health System (SUS. Distribution of the tax burden financing the SUS was calculated using micro-data from the Household Budgets Survey, 2002-2003. The Kakwani index, which shows a tax system's level of progressivity, was calculated. The Kakwani index of public financing was -0.008, and SUS financing was nearly proportional to income. From a social justice perspective this is highly undesirable in a society like Brazil, with a Gini index of 0.57. The system should be clearly progressive in order to counterbalance the country's extreme income concentration.

    Full Text Available Trata-se de um estudo descritivo, epidemiológico e analítico com abordagem qualiquantitativa. O artigo buscou identificar a relação entre cobertura da Estratégia de Saúde da Família e o aumento de ações judiciais de insulinas análogas nas regiões Sul e Nordeste do Brasil. Nos anos 2010, 2011 e 2012, o consumo de insulinas análogas foi crescente tanto na região sul quanto nordeste. A região sul, apesar de ter um SUS organizado, IDH desenvolvido e educação estruturada, apresentou falhas no programa de diabetes. Em contrapartida, a região nordeste possui IDH baixo na maioria dos municípios e educação deficiente, porém, observou-se a necessidade de reorganização dos programas voltados ao atendimento de usuários portadores de doenças crônicas, em especial, a diabetes, nessa região. Entende-se, que o fortalecimento da atenção básica como porta de entrada para o SUS, nas regiões estudadas pode minimizar o problema da judicialização da saúde.

  14. SUS 321 HTB boiler tubing with fire grained internal surface resistant to steam-induced oxidation

    1981-01-01

    Considerable amount of scale is produced by high temperature steam on the austenitic stainless steel tubes used for the superheaters and reheaters of large boilers for power generation. The scale of outer layer separates off due to the thermal stress at the time of starting-up and stopping, and causes the blocking of pipes and the erosion of turbine blades. Following the increase of nuclear power generation, large boilers are used for medium load, accordingly it is expected that the troubles like these increase. In this paper, the manufacturing method and the properties of SUS 321 HTB with fine grain internal surface are reported, which was developed to reduce the rate of growth of scale and to prevent the separation of scale. In order to prevent the separation of scale from austenitic stainless steel tubes, the reduction of scale thickness, surface treatment such as chrome plating, the use of alloys with excellent oxidation resistance, the formation of chrome-rich film rapidly, the heat treatment of cold-worked tubes and so on were carried out. The nitrification of SUS 321 H steel brought about two-phase structure of the fine grain internal surface with excellent oxidation resistance and the rest of coarse grains with high creep strength.

    This paper deals with the challenges involved in institutionalizing Monitoring and Evaluation practices within the scope of management of the Brazilian Unified Health System (SUS), based on the creation of a strategic agenda. This is structured around actions by the Federal Administration, from the perspective of defining the scope of the federative relationship. A summarized literature review is thus presented, placing into context the current SUS management process, which is based on the Pact for Health as well as theoretical and operational aspects inherent to monitoring and evaluation practices. The approach related to the strategic agenda highlights the creation of mechanisms that underpin the political and institutional decision, namely the creation of financial incentives and the development of technical mechanisms. These include organizational strategies for qualifying management teams and conducting studies and research and the dissemination of strategic information. These processes are based on the concept of providing for the management specificities in the different spheres of management based on a broad cooperation process involving teaching and research institutions and international organizations as well as the managers themselves.

    Full Text Available La creencia en la hipótesis de los mercados eficientes y la adopción de requerimientos de capital para los bancos como la mejor herramienta macroprudencial compatible con las fuerzas del mercado, reemplazó el compromiso previo de la Reserva Federal (Fed de emplear la conexión entre las operaciones de mercado abierto y los cambios en los requerimientos de reservas para limitar el crédito. Desde que se cortó esta palanca sobre la oferta crediticia, el banco central ha dependido de las operaciones de mercado abierto para lograr solamente un objetivo: influir sobre la demanda de crédito cambiando la tasa de referencia de corto plazo. La desequilibrada caja de herramientas contribuyó a un sesgo procíclico en los resultados de sus políticas que reflejó y exacerbó el sesgo procíclico del sistema financiero. El fracaso de evaluar y fortalecer sus herramientas monetarias ha socavado la habilidad de la Fed para restaurar el crecimiento económico y evitar otra crisis financiera.

    Full Text Available The Dakar-Djibouti expedition, led by Marcel Griaule, crossed Africa between 1931 and 1933. One of the participants was Michel Leiris, a young poet who had just severed his relations with the surrealist avantgarde and was in the throes of a personal crisis. This paper is about his experience in that joumey of discovery of himself, of the other and of ethnography. Representation and margination: these are the themes that will endure in L'Afrique fantôme as well as in Leiris' other writings about the Dogon and the Zar cult.

    Full Text Available The Uni ed Health System (SUS constitutes a large technological system wi- thin the Brazilian territory since it aggregates a broad and diverse materiality in organizing and managing its ows. Additionally, it has two other attributes that make it unique: high sensibility to speci cities of different places; and technical and political centralization and decentralization of its actions. The macro dimen- sion is the SUS, leading it to be understood not simply as a health system, through its: multidimensionality – elements of other life instances (social, economic, cul- tural and political; broad and unequal spectrum of actors (state and non-state who move it and the meanings of its actions; and the trans-scaleness of its con- cretion in places (local, national and international nexuses. As an infrastructure of everyday life, it is a hegemonic large technological system that acts upon objec- tive (technosphere and subjective (psychosphere conditions of existence, a con- ception that has important implications for health policy and territory integration.

Trazer o campo do real, da prática do dia a dia de profissionais, usuários e gestores mostra-se fundamental para a resolução dos problemas encontrados na assistência à saúde e para a qualificação do cuidado prestado aos sujeitos. A mudança na formação acadêmica de estudantes e professores do campo da saúde também se tem mostrado necessária. Este artigo pretende fazer uma breve recuperação histórica dos marcos das propostas de educação na saúde para profissionais do Sistema Único de Saúde (SUS, em especial no Estado de São Paulo, nos últimos anos e discutir as possibilidades de inserir metodologias ativas de ensino-aprendizagem em seu contexto. Para isso, discutimos a necessidade de aproximar a formação dos profissionais de saúde das reais necessidades dos usuários e do sistema. Isso requer mudanças institucionais, profissionais e pessoais difíceis, lentas, conflituosas e complexas. O significado da formação e a qualificação do cuidado devem estar presentes nos processos educativos para os profissionais de saúde. O ideal de profissional que queremos para o nosso Sistema de Saúde pode ser atingido se reconhecermos as necessidades e o poder criativo de cada um, ouvir o que cada um tem para dizer e refletir sobre a prática profissional inicialmente cheia de valores e de significados, os quais, muitas vezes, se perdem pelo caminho. Precisamos recuperar esses valores em nossos espaços de trabalho, nos centros formadores, nas universidades.

Presenta y actualiza los resultados de la taxonomía de cambio de régimen político y sus hechos fundamentales en la región, y examina cómo los cambios en la gobernabilidad electoral y la naturaleza de las relaciones ejecutivo-legislativas proporcionan una valoración más matizada del alcance del cambio institucional, en parte por el aprovechamiento de otros esfuerzos por evaluar el legado de la guerra civil en Centroamérica. El aporte más importante es que da cuenta de las tendencias de democratización, comparando los resultados de la posguerra en Centroamérica con los de otras 130 sociedades más que han experimentado guerras civiles entre 1940 y 2000, y sugiere que las victorias y los acuerdos negociados han conllevado, en la mayoría de los países, mejoras en los diferentes tipos de regímenes. Sin embargo, la guerra civil siempre ha dejado enormes daños en las economías, por lo que el autor explora el impacto que tuvo la guerra en la crisis económica, para entender cómo la falta de crecimiento contribuye a la decadencia política en Guatemala, Honduras y Nicaragua, pero no en El Salvador ni en Costa Rica -que también experimentó en 1948 una guerra civil -.

    2017-04-01

    This article examines the regionalization process in the Brazilian Health System, identifying frameworks and challenges of this process from critical dialogue on the subject, contextualized by the experience of the management system and in the light of an established theoretical debate in the last decade. We used the thematic content analysis of legal and documentary surveys of the regionalization process in SUS, collated by elements of the historical and political context in the period. As evidence, it appears that the regionalization process has been incremental decentralization/deconcentration of management and health actions and services. There are important challenges, particularly in relation to ensuring access and system governance structure, which contributes to critical thinking and construction of new perspectives by those who lead their implementation.

  10. A fundamental study on stress corrosion cracking of SUS 304 steel in high temperature water

    International Nuclear Information System (INIS)

    Mukai, Yoshihiko; Murata, Masato

    1985-01-01

    SCC susceptibility of sensitized SUS 304 stainless steel in high temperature water was studied. The results obtained are as follows. SCC susceptibility was increased by adding crevices to the tensile specimen surface, for the corrodent became acidified by hydrolysis in crevices. SCC susceptibility was best fit to TTS curve obtained by EPR test, not by other corrosion tests such as Strauss test or the grain boundary corrosion test in high temperature water. In addition, by giving a simulated weld thermal cycle before the sensitizing heat treatment, the sensitization was clearly promoted. This seemed to be caused by the reason that nucleation of carbide occured in the simulated weld thermal cycle process and it promoted the carbide growth and the formation of Cr poor layer around carbide in the subsequent sensitization process.

    The microstructural changes have been examined in order to study the effect of titanium addition to type 316 stainless steels on void swelling. Titanium ions of 400 keV from an accelerator have been implanted at room temperature to solution treated SUS 316 stainless steels which have the original titanium content of 0.02 wt.% to the concentration increase of titanium by 0.01, 0.02 and 0.1 wt.%. Following the preinjection of 20 at.ppm helium at ambient temperature, 400 keV-aluminium ions have been irradiated to the specimen to 40 dpa at 550, 625 and 675 0 C. The TEM observations have revealed that the void number density is drastically increased in the specimen with the content of implanted titanium of more than 0.01 wt.%, whereas the void diameter is remarkably decreased with the titanium content.

    The mechanisms of forming nanostructured, nanophase layers are revealed and analyzed in austenitic steel subjected to surface alloying using an electron-plasma process. Nanostructured, nanophase layers up to 30 μm in thickness were formed by melting of the film/substrate system with an electron beam generated by a SOLO facility (Institute of High Current Electronics, SB RAS), Tomsk), which ensured crystallization and subsequent quenching at the cooling rates within the range 105-108 K/s. The surface was modified with structural stainless steel specimens (SUS 321 steel). The film/substrate system (film thickness 0.5 μm) was formed by a plasma-assisted vacuum-arc process by evaporating a cathode made from a sintered pseudoalloy of the following composition: Zr - 6 at.% Ti - 6 at.% Cu. The film deposition was performed in a QUINTA facility equipped with a PINK hot-cathode plasma source and DI-100 arc evaporators with accelerated cooling of the process cathode, which allowed reducing the size and fraction of the droplet phase in the deposited film. It is found that melting of the film/substrate system (Zr-Ti-Cu)/(SUS 321 steel) using a high-intensity pulsed electron beam followed by the high-rate crystallization is accompanied by the formation of α-iron cellular crystallization structure and precipitation of Cr2Zr, Cr3C2 and TiC particles on the cell boundaries, which as a whole allowed increasing microhardness by a factor of 1.3, Young's modulus - by a factor of 1.2, wear resistance - by a factor of 2.7, while achieving a three-fold reduction in the friction coefficient.

    Anodic polarization curves for a solution-treated or sensitized SUS 304 stainless steel and solution-treated Fe-Ni-Cr ternary alloys containing 10%Ni and 6 to 14%Cr have been measured in deaerated 0.5 mol/l Na/sub 2/SO/sub 4/ solutions of pH 2.0 to 5.9 at 298, 523 and 553 K. Corrosion potentials for U-bend SCC test specimens of sensitized SUS 304 stainless steel have also been monitored for a long time in the same solutions as those used for the polarization measurements except that they were aerated. It was found that the differences in the current densities in the passive state, i sub(pass), between the solution treated steel and the sensitized one and also between the ternary alloy with higher Cr content and the one with lower Cr content become large with increasing temperature and decreasing pH. This means that the difference in the values of i sub(pass) between grain bodies and Cr-depleted zones along grain boundaries of sensitized steel becomes larger and susceptibility to intergranular corrosion of the sensitized steel in the passivation region becomes higher with increasing temperature and decreasing pH. Since corrosion potentials for the U-bend SCC test specimens in air-satulated solutions lie in the passive region of anodic polarization curves for the sensitized steel in deaerated solutions, the intergranular stress-corrosion cracking of the sensitized steel in high temperature water with dissolved oxygen is considered to be caused by the preferential corrosion in the Cr-depleted zone.

  20. A novel link between Sus1 and the cytoplasmic mRNA decay machinery suggests a broad role in mRNA metabolism

    2010-03-01

    Full Text Available Abstract Background Gene expression is achieved by the coordinated action of multiple factors to ensure a perfect synchrony from chromatin epigenetic regulation through to mRNA export. Sus1 is a conserved mRNA export/transcription factor and is a key player in coupling transcription initiation, elongation and mRNA export. In the nucleus, Sus1 is associated to the transcriptional co-activator SAGA and to the NPC associated complex termed TREX2/THSC. Through these associations, Sus1 mediates the nuclear dynamics of different gene loci and facilitate the export of the new transcripts. Results In this study, we have investigated whether the yeast Sus1 protein is linked to factors involved in mRNA degradation pathways. We provide evidence for genetic interactions between SUS1 and genes coding for components of P-bodies such as PAT1, LSM1, LSM6 and DHH1. We demonstrate that SUS1 deletion is synthetic lethal with 5'→3' decay machinery components LSM1 and PAT1 and has a strong genetic interaction with LSM6 and DHH1. Interestingly, Sus1 overexpression led to an accumulation of Sus1 in cytoplasmic granules, which can co-localise with components of P-bodies and stress granules. In addition, we have identified novel physical interactions between Sus1 and factors associated to P-bodies/stress granules. Finally, absence of LSM1 and PAT1 slightly promotes the Sus1-TREX2 association. Conclusions In this study, we found genetic and biochemical association between Sus1 and components responsible for cytoplasmic mRNA metabolism. Moreover, Sus1 accumulates in discrete cytoplasmic granules, which partially co-localise with P-bodies and stress granules under specific conditions. These interactions suggest a role for Sus1 in gene expression during cytoplasmic mRNA metabolism in addition to its nuclear function.

    Full Text Available El propósito de este artículo es evidenciar, mediante el método etnográfico, las creencias sobre la obesidad de niños y niñas en edad escolar y las de sus progenitores, pertenecientes a una escuela urbana y pública de San José, Costa Rica. Los resultados apuntan hacia las creencias negativas de la niñez respecto a sus pares con obesidad y sus implicaciones psicosociales y afectivas. En relación con los progenitores se señalan las causas y estrategias de control, las implicaciones de la obesidad, referente a enfermedades físicas y emocionales; el papel del hogar y de la escuela en su prevención. Se concluye que los niños y las niñas creen que la obesidad no es una enfermedad, sino u na expresión fenotípica, a la cual le dan grado de relatividad o de escala y la consideran no deseable, resultado que concuerda con la de sus progenitores. Las niñas participantes con obesidad expresaron sus posiciones de defensa y molestia, en relación con experiencias burlescas. Al contrario de sus hijos e hijas, la mayoría de los progenitores sí cree que la obesidad es una enfermedad o un problema de salud o de estética. Además, estiman que esta se controla utilizando una dieta saludable y equilibrada, dando consejos sobre las consecuencias físicas y emocionales de la obesidad y ofreciendo modelos de personas saludables. Por lo tanto, los progenitores y el personal docente creen que la escuela poco puede hacer respecto a la alimentación saludable del alumnado, pues el hogar es el lugar que tiene un papel primordial.

    Full Text Available Bajo cualquier esquema de enseñanza-aprendizaje de la matemática, cuando al alumno se le señalan errores en su trabajo, puede, en general, adoptar tres tipos de actitud: una actitud negativa, bajo la cual el alumno considera que sus errores son sencillamente un síntoma de su fracaso; una actitud neutra o indiferente ante sus errores; o una actitud positiva, considerándolos como un medio para aprender y planteándose como reto el superarlos. Este artículo muestra una investigación que abordó el estudio de actitudes vinculadas al proceso de aprendizaje de la matemática. Su objetivo fue describir la actitud que el estudiante de ingeniería de la Uni- versidad del Zulia exhibe frente a sus errores cuando aprende matemática. La sus tentación teórica se baso en Brousseau (2001, Briñol et al. (2007 y los autores Pallí y Martínez (2004. Se utilizó una escala AEAM (Actitud hacia el Error del Alumno de Matemática, tipo Likert con 6 alternativas de respuesta que consta de 36 ítems, en su segunda versión, actualizada por los autores. El instrumento fue validado mediante juicio de expertos y se determinó que era de alta confiabilidad, con un alpha de Cronbach de 0.9073. Se concluyó que los participantes, en su mayoría, mostraron una actitud moderadamente positiva hacia sus errores, que al no estar ubicada en el extremo positivo deseable refleja una actitud débil que no garantiza una conducta adecuada hacia los errores, pero que sin embargo es sus ceptible de ser mejorada hacia una actitud francamente positiva.

    Full Text Available Savremene konstrukcije motora SUS treba da zadovolje zahtev za malu potrošnju goriva i ulja za podmazivanje, pre svega zbog ekoloških a zatim i energetskih i ekonomskih razloga. Pošto se pretpostavlja da će konvencionalni motori SUS još dugo dominirati kao pogonski agregati, raznim konstrukcionim merama pristupa se smanjenju potrošnje goriva, a time i smanjenju izduvne emisije. Pre svega, radi se o optimizaciji radnog ciklusa primeni varijabilnog stepena sabijanja, primeni varijabilnog razvoda radne materije, boljim sprezanjem sa gasnim mašinama, itd. Značajan potencijal za povećanje ekonomičnosti rada motora jeste u smanjenju mehaničkih gubitaka. Najveći udeo u mehaničkim gubicima predstavlja trenje po-kretnih delova motora, pre svega delova klipno-cilindarskog sklopa. Zbog toga se posebna pažnja posvećuje izučavanju mehanizma trenja, koji je inače veoma složen. / One of demands for modern designed IC engines is low fuel and lubricant consumption because of reasons concerning ecology as well as energy and economy. The symptom is that conventional IC engines will be the first choice as a power source for numerous applications in the future. Therefore many changes and improvements in design need to be done for further decrease of fuel consumption followed by the decrease of exhaust emission. First of all, there is the optimization of the working cycle, the application of variable compression, the application of variable valve control, better coupling with gas machines, etc. Significant potential for efficiency improvement of IC engines is in reducing mechanical losses. Mechanical losses in IC engines are caused mostly by friction between the mobile parts of the engine (piston-cylinder assembly. Therefore, continual attention to the research process of studying friction problems would be necessary.

  14. Low-cycle fatigue properties of SUS304 stainless steel in high-temperature sodium

    International Nuclear Information System (INIS)

    Hirano, M.; Komine, R.; Kitao, K.; Nihei, I.; Yoshitoshi, A.

    Low-cycle fatigue tests in sodium and in air have been performed to investigate the influence of a high-temperature sodium environment on the strain-controlled fatigue behaviour for SUS304 stainless steel. The oxygen concentration in sodium was 2.4 ppm at the cold trap temperature of 145 deg. C. Tests in both environments were conducted at 450 deg. C, 550 deg. C and 650 deg. C at a constant strain rate of 1x10 -3 /sec with a fully-reversed triangular waveform and a zero mean strain. The fatigue life of SUS304 stainless steel in sodium at 450 deg. C, 550 deg. C and 650 deg. C was greater than those in air at the same temperature except at higher strain range (>0.8%) at 650 deg. C, and this difference had a tendency to increase as the total strain range decreases. At the higher total strain range at 650 deg. C, there was no marked difference between both environments. As the temperature increased, the fatigue life in sodium and in air decreased, and the Nsub(f sodium)/Nsub(f air) ratio also decreased. Microscopic examination of specimens tested in sodium and in air at 450 deg. C, 550 deg. C and 650 deg. C revealed no difference in the microstructure, but few surface cracks were observed on specimens tested in sodium than in those tested in air. Fractography of specimens tested in air at 450 deg. C, 550 deg. C and 650 deg. C revealed well-defined striations. But, in sodium, striations on specimens tested at 450 deg. C and 550 deg. C showed obscure configuration and it was difficult to find out, whereas, at 650 deg. C in sodium intergranular fracture was observed. The specimens tested in sodium had a longer fatigue life than those tested in air because the latter are subjected to considerable oxidation, while the former are free of such chemical action. Accordingly, it is concluded that crack initiation and propagation are more likely to occur in air than in sodium. (author)

    Full Text Available RESUMEN Los hongos-roya (Uredinales, Basidiomycetes representan uno de los grupos de microorganismos fitoparásitos más diversos y con mayor importancia económica mundial en la producción agrícola y forestal. Se caracterizan por ser patógenos obligados y por presentar una estrecha coevolución con sus hospedantes vegetales. Su taxonomía se ha basado fundamentalmente en el estudio de caracteres morfológicos, resultando en muchos casos en la formación de taxones polifiléticos. Sin embargo, en los últimos años se han tratado de incorporar herramientas moleculares que conduzcan a la generación de sistemas de clasificación basados en afinidades evolutivas. En esta revisión se ofrece una mirada general a las características de los uredinales, enfatizando en el surgimiento reciente de estudios filogenéticos que plantean la necesidad de establecer una profunda revisión de la taxonomía de este grupo. Finalmente se alerta sobre la necesidad de que en dichos estudios taxonómicos se incluya un alto número de especies de royas neotropicales, pues esta zona es reconocida no sólo por su alta diversidad de hongos-royas, sino también por las características únicas de sus ciclos de vida. Palabras clave: filogenia, hongos-roya, Puccinia, secuenciación, teliosporas.

    Full Text Available The city of Buenos Aires was founded, for the second time 1580 essentially as an outpost of the Spanish Empire to be protected from Indian attacks and possible foreign incursion, basically Portuguese in origin. Thus, from the beginnings of the city's founding, African slaves were used for the defense of the city. They acted in the urban militias, and were outstanding in the defense and re-conquest of the city when the English attacked in 1806- 1807. Innumerable prizes and eulogies were followed by integration of segregated divisions with a white officer corps.After 1813, a series of decrees ordered owners to exchange slaves for use in the Wars of Independence. Thus, property owners were obliged to sell to the State a number of their slaves according to the work performed by the slaves. The slaves would enter the armies as free persons and would serve five years as 'front line" soldiers in order to obtain their freedom. This article studies the participation of the Afro-Argentines in the distinct 'fronts" of the armies of liberation. The paper also reflects on the opinions of the generals who commanded Afro-Argentine troops.//La ciudad de Buenos Aires fue fundada, por segunda vez, en 1580 esencialmente como un puesto de avanzada para que los españoles se protegieran de los indígenas y de una posible incursión extranjera de origen portugués.

    2018-02-05

    In eukaryotes, the nuclear export of mRNAs is essential for gene expression. However, little is known about the role of mRNA nuclear export in the important fungal pathogen, Candida albicans. In this study, we identified C. albicans Sus1, a nucleus-localized protein that is required for mRNA export. Interestingly, the sus1Δ/Δ displayed hyper-sensitivity to extracellular oxidative stress, enhanced ROS accumulation and severe oxidative stress-related cell death. More strikingly, although the mutant exhibited normal activation of the expression of oxidative stress response (OSR) genes, it had attenuated activity of ROS scavenging system, which may be attributed to the defect in OSR mRNA export in this mutant. In addition, the virulence of the sus1Δ/Δ was seriously attenuated. Taken together, our findings provide evidence that the mRNA export factor Sus1 plays an important role in oxidative stress tolerance and pathogenesis. Copyright © 2018 Elsevier Inc.

    Full Text Available Los estudiosos de la familia residencial de las distintas disciplinas sociales en México no han tomado en cuenta las diferentes tradiciones culturales del país y han partido de un modelo de familia, como si México fuera un país homogéneo. El presente trabajo plantea el concepto de “sistema familiar mesoamericano”, que permite aprehender un tipo específico de ciclo de desarrollo de los grupos domésticos, característico de amplios sectores de la población rural de México. Uno de sus rasgos es la residencia virilocal, que favorece la formación de nuevas parejas sin necesidad de contar con vivienda propia. La consecuencia es una baja edad en el momento del matrimonio y el rápido crecimiento de la población, por lo que se puede hablar de un régimen demográfico asociado con este sistema familiar.

    Cyclic voltammograms of SUS 304 stainless steel in various neutral solutions such as Na 2 SO 4 at high temperature were measured, as a successive study to previous report in which effects of temperature and pH on polarization behavior of stainless steel were studied. In this measurement Ag/AgCl reference electrode and platinum counter electrode were used in a static autoclave lined with inconel. Passive films formed in various conditions were analysed by electron diffraction and Auger spectroscopy. Results obtained were compared with anodic behavior of iron, chromium and nickel and with thermodynamical stabilities of their compounds. The main results are summarized as follows. (1) Stainless steel shows such electrochemical behavior as active dissolution, passivation and transpassivation in a deaerated neutral solution at 250 0 C after fully reductive treatment of the specimen. In air-saturated solution, the peak of active dissolution is not observed. In the passive range there are intermediate oxidation and reduction peaks, and it is assumed that dissolved ionic species are oxidized to form oxide of spinel type and higher oxidized state successively at these peaks. (2) Electrochemical behavior of specimens in 0.1 M sulfate, -phosphate and -carbonate solutions are almost the same and rather thick films form in these solutions. On the other hand, specimens are easy to passivate in borate and -nitrate solution, and their passive films are thin. (author)

Dado que el principalactivo en la riqueza de los hogares es la vivienda, es importante analizar sucomportamiento y entender los canales por los cuales el cambio en la valoración de este activo, puede generar cambios en la riqueza, y por ende, variaciones en el consumo agregado. Para ello se desarrolla un modelo en el que la vivienda hace de colateral y los hogares pueden realizar inversión en este sector. En el modelo se incluyen restricciones al crédito y costos de ajuste a la inversión, en orden de analizar sus implicaciones en el consumo. Al final, se obtiene que los hogares que enfrentan bajos costos de ajuste en la inversión y que, adicionalmente utilizan a la vivienda como colateral, enfrentan mayores fluctuaciones en el consumo dado el efecto del acelerador financiero.

  5. Thermal fatigue behavior of a SUS304 pipe under longitudinal cyclic movement of axial temperature distribution

    Yamauchi, Masafumi; Ohtani, Tomomi; Takahashi, Yukio

    1996-01-01

    In a structural thermal fatigue test which imposed an oscillating axial temperature distribution on a SUS 304 pipe specimens, different crack initiation lives were observed between the inner and the outer surfaces, although the values of the von-Mises equivalent strain range calculated by FEM inelastic analysis were almost the same for both surfaces. The outer surface condition was an in-phase thermal cycle and an almost uniaxial cyclic stress (low hydrostatic stress). The inner surface condition was an out-of-phase thermal cycle and an almost equibiaxial cyclic stress (high hydrostatic stress). A uniaxial thermal fatigue test was performed under the simulated conditions of the outer and inner surfaces of the pipe specimen. The in-phase uniaxial thermal fatigue test result was in good agreement with the test result of the pipe specimen for the outer surface. The out-of-phase uniaxial thermal fatigue test which simulated the inner surface condition, showed a longer life than the in-phase uniaxial test, and thus contradicted the result of the structural model test. However, the structural model test life for the inner surface agreed well with the uniaxial experimental measurement when the strain range of the inner surface was corrected by a triaxiality factor

    Full Text Available Technological incorporation is a central topic among the concerns regarding health care systems. This paper discusses the role of technology dynamics in health systems' cost increases, suggesting two different approaches - a 'pragmatic-economic' approach and a 'rational-defensive' approach - as guidelines to explain the reasons for this centrality. The paper shows how judicialization results from this situation and discusses two doctrinal views - 'reserve for contingencies' and 'rational use' - as the views that usually guide the debates in the courts and among health policy makers. The paper suggests that the attitude currently prevalent in the Brazilian judiciary system can prejudice the principle of equity by improperly evaluating the principle of integrality. We present a brief genealogy of HTA and a timeline of HTA in Brazil. We also discuss the relevance and the impact of Law 12401/2011, which regulates the principle of integrality in the Unified Health System (SUS and propose three challenges to the development of HTA actions aiming at technology incorporation in Brazil. Finally, we discuss the entry and the role of private health insurance companies, emphasizing changes in the scenario and in their position.

    Creep-fatigue is a fatal failure mode of high temperature structural materials. It is recognized that the law of linear damage, according to which creep-fatigue damage is expressed by the sum of the creep damage and the fatigue damage, is inadequate to evaluate creep-fatigue damage. This is due to the fact that the law of linear damage does not include the effect of interaction between the creep damage and the fatigue damage. Consequently, development of direct measurement of damage accumulation on the sample of interest is required for plant life evaluation. In this study, the induced current focusing potential drop (ICFPD) technique was used to evaluate the depth of small surface cracks in SUS316FR stainless steel which was subjected to creep-fatigue damage. It is shown that the potential drop increased during the micro-crack initiation and propagation. Correspondingly, the ICFPD technique applied to estimate micro-crack depth changes was used to accurately evaluate the residual life of creep-fatigue damaged structural materials. (author)

    Light-absorbing aerosols, such as black carbon (BC), are major contributors to the atmospheric heating and the reduction of solar radiation reaching at the earth's surface. In this study, we investigate light-absorption and scattering properties of aerosols (i.e., BC mass concentration, aerosol solar-absorption/scattering efficiency) in the Kathmandu valley during Sustainable atmosphere for the Kathmandu valley (SusKat)-ABC campaign, from December 2012 to February 2013. Kathmandu City is among the most polluted cities in the world. However, there are only few past studies that provide basic understanding of air pollution in the Kathmandu Valley, which is not sufficient for designing effective mitigation measures (e.g., technological, financial, regulatory, legal and political measures, planning strategies). A distinct diurnal variation of BC mass concentration with two high peaks observed during wintertime dry monsoon period. BC mass concentration was found to be maximum around 09:00 and 20:00 local standard time (LST). Increased cars and cooking activities including substantial burning of wood and other biomass in the morning and in the evening contributed to high BC concentration. Low BC concentrations during the daytime can be explain by reduced vehicular movement and cooking activities. Also, the developmements of the boundary layer height and mountain-valley winds in the Kathmandu Valley paly a crucial role in the temproal variation of BC mass concentrations. Detailed radiative effects of light-absorbing aerosols will be presented.

    Full Text Available El agua es actualmente una cuestión política y geoestratégica de gran importancia mundial. Colombia, una de las potencias hídricas del mundo, abastece solamente la mitad de sus habitantes. La degradación del recurso y de los ecosistemas que lo generan, la polución, el despilfarro, el crecimiento de la población y su concentración en los centros urbanos, así como la falta de equidad en el acceso al agua, son algunos de los problemas que atentan contra las posibilidades de un desarrollo sostenible en el país. Con el fin de dar cuenta de los valores acordados al agua, se propuso un estudio que busca identificar la representación social que de ésta tiene un grupo social colombiano. Se entrevistó a 150 estudiantes de ciencias sociales en la ciudad de Bogotá. El análisis prototípico y categorial nos permitió plantear algunas hipótesis con respecto a las características de la representación social del agua elaborada por el grupo participante

    Under the condition of mechanical load, on which the thermal stress due to temperature change is superposed, the deformation behavior of structural materials is affected by not only loading history but also temperature history. Also at the time of working materials, the case that the relation between plastic deformation and temperature change becomes a problem is not few, such as cold working after hot rolling. In this study, the effect of temperature change exerted on the plastic deformation of SUS 304 stainless steel was examined, as this material has been frequently used as a high temperature structural material. That is, the plastic deformation behavior at a certain temperature after prestrain was applied at a different temperature was experimentally determined under various temperature and load conditions. Moreover, the quantitative evaluation of the results obtained was attempted by using the concept of an equal plastic strain curved surface. The test pieces and the experimental method, the behavior in uniaxial loading and the behavior in combined loading are reported. (Kako, I.)

    In the Fukushima Dai-ichi nuclear power plant, seawater and natural river water were poured into the spent nuclear fuel pools (SFP) for emergency cooling. At the early stage of the accident, corrosion of SFP's materials was worried because of high chloride ion concentration from seawater. The chloride ion concentration of the present time was decreased by dechlorination operation of feeding water of SFPs. However, the water was not treated in the viewpoint of microbial breeding and SFPs were in contact with open atmosphere, so that many microbes could be alive in the cooling water. Some researchers have reported microbially induced corrosion (MIC) occurred in the natural seawater or river water. So, we attempted to examine the ability of MIC occurrence by using of corrosion potential analysis. Corrosion potential measurements were performed in test solutions using SUS304 simple plate, creviced and welded samples. Natural river water in Ibaraki prefecture was used as standard test solution, and some amounts of NaCl and nutrient broth (NB) were added to the other solutions. Temperatures of these solutions were kept in 303 K. Growth of microbes in the test solution was confirmed using test kit. Corrosion potentials of all samples rose to about 300 mV nobler than the initial values in the NB added solution. The potentials of the welded samples more easily rose than the simple plate. These potential changes are attributed to the biofilms formed on the sample surface. (author)

    Effect of overloading types on the fatigue crack growth threshold of SUS316 was studied. Three types of overloading: tensile (type I), tensile+compression (type II), and tensile+compression+tensile (type III) were applied to compact tension specimens, then the fatigue tests were carried out to determine the apparent threshold stress intensity factor range Δ N K th . The results showed that the Δ N K th values increased with increasing the single tensile overload stress intensity factor K ov above the K ov > ΔK th . Additional compressive loading (type II) led to decrease in Δ N K th to the ΔK th =6MPa×m 1/2 within the all tested K ov values ranging from -45MPa×m 1/2 ≤K ov 1/2 . This is due to the fact that the compressive residual stress field at crack tip changed to the tensile stress field by the compressive loading. Furthermore, the Δ N K th values increased again by additional tensile overloading (type III) from ΔK th to the almost same Δ N K th values as that by Type I loading. This means that the almost same compressive residual stress field formed by type III overloading as the type I overloading. The experimental Δ N K th increasing behaviors were discussed by Finite Element Method (FEM). (author)

In the case of Basic Health Units (BHU, receiving a very large flow of people, with spontaneous demand and schedules, it is important to take care of the logistics of care, avoiding unnecessary presence in BHU. Teams of Sorocaba's BHU, through the Continuing Education Strategy, were encouraged to discussions and find ways for customer service improvements. The sheer volume of people daily in units seen as a problem which compromised the quality of care is what motivated the analysis and improvement of processes. Using methods of process modeling, indicators and change management, have improved two processes related to the flow of people in UBS, the patients with multiple schedules in the same month and the patients who seek continuous use drugs.

Sería extremadamente simple sintetizar la formidable pugna como un debate entre comunismo y capitalismo. En realidad, se trataba de dos estrategias más que de dos revoluciones, con sus estéticas y deontologías respectivas, con lo que los ideales, al final, se encontraban seriamente amenazados en el núcleo mismo donde se formaban. Ahora sólo permanece en pie una de estas fuerzas, pero en modo alguno puede considerarse ésta el ideal triunfante, sino tan sólo el ideal subsistente, es decir, el que todavía no se ha formado.

Sin embargo, un alto porcentaje de estas relaciones fracasan. Además, existe una evidencia empírica limitada acerca de este ámbito de estudio en la industria turística, y muy especialmente en el sector de la hostelería. Ante este reto, el objetivo del presente trabajo es analizar los antecedentes del éxito de la relación restaurante-cliente a partir de una secuencia causal: dimensiones del valor entregado  confianza y compromiso  éxito de la relación. A partir de una muestra de 150 restaurantes, los resultados indican que la calidad de servicio y el prestigio, como elementos del valor entregado, son antecedentes directos del compromiso del gestor del servicio con su grupo de clientes e indirectos del éxito de la relación empresa-cliente. Además, la confianza del gestor del servicio con sus clientes y el compromiso que adquiere con ellos se convierten en antecedentes significativos del éxito de la relación con los mismos.

    Full Text Available En el contexto sociocultural actual los avances científicos en la biología,especialmente en la Genética, afectan de muchas formas los interesespúblicos y privados. Por ello, se torna necesario explicitar el conceptobiológico de vida, dado que esa explicitación podrá guiar el establecimentode límites éticos de determinadas inversiones de instituciones estatales,privadas y de legisladores que comúnmente recurren al apoyo de la cienciapara fundamentar sus opiniones. Bajo esta perspectiva articulamosargumentos para fundamentar la concepción relacional de la vida encontraposición al abordaje esencialista o de simple listado de atributos. Estees muy utilizado para definir al ser vivo, mas necesariamente es pocoabarcador y esclarecedor. Tal abordaje ha producido un amplio número dedefiniciones para el concepto sobre lo que es la vida, lo que resulta más enconfusiones que en esclarecimientos. Al contrario, la concepción relacionalde vida parte de la definición de que la vida es  adaptación flexible. Taldefinición emerge a partir de investigaciones realizadas sobre la vidaartificial y privilegia una metafísica de procesos al revés de una metafísicade sustancias. Entretanto, aunque el concepto relacional de la vida tengaventaja sobre la mayoria de los demás, tal vez no sea útil para ayudar adefinir mejor los límites y prerrogativas éticas y legales de intervencionesque amenacen vidas individuales, tales como el aborto y la eutanasia y noacarrear prejuicios o estabelecer privilegios de alcances sociales escasos.Concluimos con una apreciación jurídica del concepto relacional de la vida,especialmente la vida humana y su tutela en Brasil, informando lanaturaleza, los límites y la extensión de esa protección.

Esta investigación, que forma parte del estudio comparativo transnacional «Worlds of Journalism Study», analiza los datos de una encuesta realizada en España (representativa y estratificada por tipo de medio y por Comunidad Autónoma a 390 periodistas de 117 medios de comunicación, quienes fueron consultados sobre su trabajo para detectar las funciones profesionales con las que más se identificaban. El estudio señala seis roles: el de perro guardián, el altavoz de la ciudadanía, el instructor de la audiencia, el favorecedor del statu quo, el que entretiene a la opinión pública y el difusor de información objetiva. En línea con la evolución política, económica y social de los últimos años en España, los profesionales se identifican más con el papel de altavoz de la ciudadanía. Esta función desplaza en importancia al rol protagonista de los estudios similares más recientes sobre periodistas españoles: el de difusor de la información objetiva. Se hallan también dos grandes grupos de periodistas: los estimuladores y los narcotizadores de la opinión pública. Además, se observa que algunos factores organizacionales (en concreto, la propiedad del medio y otros individuales (el género, la edad y los años de experiencia laboral influyen significativamente en las percepciones de los roles profesionales.

    Full Text Available The potato is one of the main strategic crops in the Russian Federation, Belarus and Kazakhstan. Currently, we have achieved significant advances in the understanding of metabolic mechanism of carbohydrate and interconversion «sucrose – starch» in potato tubers. Sucrose synthase (Sus is a key enzyme in the breakdown of sucrose. Sucrose synthase (Sus is catalyzing a reversible reaction of conversion sucrose and UDP into fructose and UDP-glucose. The identification and subsequent characterization of the genes encoding plant sucrose synthase is the first step towards understanding their physiological roles and metabolic mechanism involved in carbohydrate accumulation in potato tubers. In the present work the nucleotide and amino acid polymorphism of the Sus4 gene fragments containing sequences of the sucrose synthase domain were analyzed. Sus4 gene fragments (intron III – exon VI in 9 potato cultivars of Russian, Kazakh and Belarusian breeding were analyzed. The polymorphism of the Sus4 sucrose synthase domain sequences was first examined. The length of analyzed fragment varied from 977 b.p. (cultivars Favorit, Karasaiskii, Miras to 1013 b.p. (cultivars Zorochka, Manifest, Elisaveta, Bashkirskii. It was demonstrated that the examined sequences contained point mutations, as well as insertions and deletions. The common polymorphism level was 5.82%. It was shown that the examined sequences contained 58 SNPs and 4 indels. The most variable were introns IV (12.4% and V (9.18%. The most variable was exon IV. 7 allelic variants were detected. 6 different amino acid sequences specific to different varieties were also identified.

    Full Text Available Para la industria salitrera de la árida provincia de Tarapacá, el transporte ferroviario era una necesidad muy cara, costando en una época hasta cien veces el precio por ton-km del transporte marítimo que llevaba el salitre a Europa. Los primeros ferrocarriles para el transporte del salitre nacieron de concesiones del gobierno peruano pero, antes del fin formal de la Guerra del Pacífico, la empresa dueña de las líneas se reconstituyó, en Londres, asumiendo el nombre Nitrate Railways Co. Ltd., conocida en Chile como simplemente el Ferrocarril Salitrero, con mayúsculas. Los directores del Ferrocarril Salitrero consideraron que sus concesiones confiriesen derechos exclusivos, pero, después de una larga batalla legal, el mercado se abrió para otros ferrocarriles salitreros, con minúsculas. Varias fueron las causas de las tarifas caras del Ferrocarril Salitrero en sus primeros años, algunas relacionadas con sus costos intrinsecamente altos, pero influyó su posición monopólica. La competencia que le presentaban los ferrocarriles de Agua Santa y de Junín, a partir de 1894 le obligó a reducir algunas de sus tarifas. Los ferrocarriles de competencia tenían rutas más directas a los puertos, pero cayeron víctimas de la decaída catasrófica de la industria salitrera tarapaquense en 1930, aunque el Ferrocarril Salitrero logró sobrevivir como empresa independiente durante 20 años más, teniendo que disputar el reducido tráfico que había con el nuevamente inaugurado Ferrocarril de Iquique a Pintados, que fue promovido por el Estado para romper el monopolio del Salitrero sobre el transporte de las oficinas del sur y centro de la provincia, la mayoría de las cuales se habían extinguido antes de que entrara en pleno funcionamientoThrough Chile's arid Province of Tarapacá, no navigable rivers flow, and before the advent of mechanized road transport, railways were an expensive necessity for the nitrate industry.

Parte-se da hipótese de que a atenção básica à saúde, ação integrada de promoção, prevenção e recuperação da saúde da população, embora seja espaço político para produção de saberes e tecnologias partilhadas de poder, tem pouca influência no reordenamento do mercado em saúde no Brasil, comprometendo seu potencial para inversão do modelo de atenção. Este artigo tem como objetivos contextualizar a atenção básica na gestão da assistência à saúde no SUS; refletir teoricamente sobre a reorganização dos serviços a partir da atenção primária à saúde (APS, considerando as dimensões econômicas das políticas sociais. A pesquisa teórica e documental teve abordagem qualitativa. Fez-se análise crítica de documentos oficiais, nacionais e internacionais. Conclui-se pela necessidade de uma atenção básica melhor articulada à média e à alta complexidades, capaz de interferir na lógica da oferta a partir da demanda e reduzir iniquidades.The limits and possibilities concerning the restructuring of the health services of Sistema Único de Saúde (SUS - National Health System are discussed based on primary care. The hypothesis is that primary care, which means integrated action of promotion, prevention and recuperation of the population's health, despite the fact that it is a political space for the production of knowledge and of power-sharing technology, it has little influence on the reorganization of the health market in Brazil, which negatively affects its potential concerning the inversion of the primary care model.

Se aplicaron técnicas cuantitativas y cualitativas de investigación (grupos focales. El cuestionario incluyó variables sociodemográficas, variables relacionadas con el consumo, y variables relacionadas con la percepción del riesgo de fumar. En lo cualitativo, se exploraron propuestas para reducir esta conducta. El 32 % de los médicos y el 46 % de las enfermeras fumaban en el momento de la encuesta. Los médicos aportaron más fumadores moderados y severos, y se sintieron menos limitados a fumar en sus centros de trabajo que las enfermeras. El 17 % de ellos y el 20 % de las enfermeras aceptó que fumar le representó más beneficios que daños. En ambos grupos se evidenció una percepción distorsionada del riesgo de fumar. Entre las propuestas hechas por los propios trabajadores, que deberán tenerse en cuenta al implementar proyectos de intervención, se encontraron: fortalecer en la atención primaria los servicios de cesación para fumadores, hacer cumplir en los centros de salud las regulaciones para fumar, aplicar sanciones a los violadores de lo reglamentado y divulgar de manera sistemática la importancia de la función modélica de los médicos y enfermeras, como importantes agentes de cambios en la sociedadPhysicians and other health professionals are important sources of influence to attain positive changes of the smoking levels.

Muchos son los estudios que se han centrado en comprobar los resultados de este proceso de inclusión y en la figura de los alumnos con necesidades educativas especiales, considerando los elementos necesarios para conseguir su integración, su rendimiento, su adaptación social, sus interacciones con los compañeros, etc. Sin embargo, muchas veces se ha olvidado contar con la opinión de los propios «afectados»: los alumnos. Si realmente se quiere atender las necesidades de éstos, lo más lógico es recurrir a ellos para conocer cómo perciben la situación y descubrir cuáles son sus verdaderas necesidades. Este artículo presenta la visión que tiene el alumno sobre su propia realidad.ABSTRACT: Inclusive schools meeting the needs of all students are a primary goal of all general education. Much research has been done on the results of inclusión, on students with special needs, and on what is necessary for their integration, adequate performance, social adaptation, peer interaction, etc. However, their own view has often been ignored: if the aim is to meet these student's needs, their perceptions should be taken into account for a more accurate assessment of what their needs really are.

  17. Elemental redistribution in coloured films on SUS304 stainless steel produced by current pulse method

    1996-01-01

    Coloured films are deposited on an SUS304 substrate by the square wave current pulse method in a 2.5 M CrO 3 + 5 M H 2 SO 4 solution at 75 C. The absolute ratio of anodic to cathodic charge density and the corresponding final value of cathodic potential provide an easy and appropriate approach to the control of colour in the current pulse colouring method. This is proved in this study for a frequency region lower than 1 Hz. The corresponding cathodic potential increases with increasing dwell time in the negative applied current region and is related to the colour tone of the deposited film. The total time required to obtain the same thickness of coloured film is shorter at lower frequency than at higher frequency, which takes more time to charge the double layer. The thickness of the coloured films is determined by both Auger electron spectroscopy (AES) and secondary ion mass spectrometry (SIMS) depth profiling and is of submicron order. The film thickness is proportional to the introduced total charge per unit area in the current pulse colouring process. CrO + and FeO + ions are observed in the coloured films and their concentrations increase as the colouring time is increased. The Fe concentration in the coloured films is lower than that in the substrate and decreases with the colouring time. It is the iron species that first becomes involved in the anodic reaction and the spinel oxide structure of iron and chromium is present in the coloured films. (orig.)

    Full Text Available Se estudia el impacto de los subtítulos en el mismo idioma de la narrativa audiovisual según el idioma del receptor (nativo o extranjero. Estudiantes de dos universidades australianas y una española fueron asignados al azar a uno de dos grupos experimentales en los que se veía un drama con la banda sonora original en inglés con subtítulos en esa misma lengua (n=81 o sin subtítulos (n=92. La muestra incluía un grupo control de hablantes nativos de inglés, además de grupos de hablantes nativos de chino mandarín, coreano y español con inglés como lengua extranjera. Como medidas post-hoc, los participantes reportaron, mediante escalas Likert, su percepción de presencia, transporte, realismo percibido, identificación con los personajes y disfrute. Los resultados muestran que los subtítulos no reducen las medidas de inmersión. Además, que los subtítulos producen mayores puntuaciones de transporte, identificación con los personajes y percepción de realismo, cuya varianza se explica, esencialmente, por la primera lengua de los receptores y sus hábitos de visionado. Asimismo, los resultados señalan que ni a la presencia y ni al disfrute les afectan la condición experimental o el idioma del receptor. Finalmente, muestran que el transporte es la medida más reveladora de la inmersión porque produce las correlaciones más fuertes y consistentes, aparte de ser un predictor significativo del disfrute de los espectadores.

Se realizó una investigación cuantitativa, de tipo explicativo, no experimental, longitudinal, exploratorio y correlacional; la población estuvo conformada por 4.168 Pymes colombianas que reportan sus estados financieros a la Superintendencia de Sociedades en el período 2004-2009. Los resultados muestran que las Pymes se financian principalmente con recursos propios, en menor grado con pasivos de corto plazo y en baja proporción con pasivos de largo plazo, siguiendo un patrón similar al explicado por la teoría de selección jerárquica (pecking order theory; igualmente, los estadísticos sugieren limitaciones importantes para generar ingresos y atraer fuentes de financiación que fortalezcan su desempeño. Los indicadores de liquidez, eficiencia y rentabilidad evidencian una situación desfavorable para el sector, obstaculizando la obtención de nuevos recursos. Finalmente, del análisis correlacional se infiere que los indicadores de eficiencia en la gestión empresarial son los que más se asocian significativamente con el acceso a fuentes de financiación externas a las organizaciones.

    Full Text Available La mera presencia de recursos tecnológicos en los centros y las altas capacidades de los alumnos de la «Generación Tecnológica» o «Generación Z», no son suficientes para desarrollar en los alumnos la competencia digital. La clave fundamental viene determinada por las competencias tecnológicas y pedagógicas de los docentes. En este trabajo, se pretende analizar el nivel de competencias en TIC de los profesores de Primaria y Secundaria estableciendo un marco competencial de referencia adaptado al ámbito educativo español, utilizando como base los estándares establecidos por la UNESCO en el año 2008 y reformulados en el año 2011. Para ello, se realizó un cuestionario que permitió establecer el perfil de formación docente en TIC del profesorado de la muestra (80 colegios y 1.433 profesores de la Comunidad de Madrid, para estudiar las características del profesorado mejor formado para el desarrollo de la competencia digital que establece el Ministerio de Educación de España. Los resultados muestran una alarmante diferencia entre las competencias que debieran tener los profesores para desarrollar la competencia digital en sus alumnos y la que verdaderamente tienen. Las competencias digitales del profesorado son muy relevantes en el desarrollo de procedimientos de aprendizaje que introduzcan las tecnologías como herramientas al servicio de la educación y este estudio nos permitirá tomar decisiones en política de formación inicial y a lo largo de la carrera profesional del profesorado.

    Full Text Available ste documento busca responder el interrogante sobre cuáles son los efectos del trabajo infanto-juvenil en la educación y salud de las niñas y niños colombianos. Haciendo uso de la Encuesta Nacional de Calidad de Vida de 2003, se concluye que la vinculación temprana al mercado laboral de las y los niños con edades entre 12 y 17 años afecta negativamente su asistencia escolar, aumenta sus niveles de extraedad educativa y deteriora la percepción de su estado de salud. Para los menores entre 7 y 11 años, la relación entre trabajo infantil y la educación no es tan clara, debido posiblemente al bajo número de niños trabajadores en este rango etáreo y a la gran cobertura escolar en básica primaria que tiene Colombia. La no influencia inmediata en la salud de los oficios realizados, y la ejecución de labores más suaves respecto a las hechas por los niños de mayor edad, podrían ser algunas de las causantes de que el perjuicio en la salud de las y los niños trabajadores no sea evidente en la población de 7 a 11 años. Las pruebas empíricas contenidas en este artículo predicen que los programas encaminados a aumentar la cobertura y calidad educativa y, máxime, a impulsar y facilitar la asistencia escolar, principalmente en niveles superiores a la básica primaria, serán grandes aliados en la erradicación del trabajo infanto-juvenil en Colombia.

    Full Text Available Several elements of the story narrated by Herodotus (I, 163 about Arganthonius, King of Tartessos, raise questions on the historical reality of this character: first, the mythical aspects of his figure, since he can be considered both a realization of the picture of the friendly king who welcomes travelers and an embodiment of the idea of a far-off and mysterious source of wealth; second, the chronology of his reign and his life, in which a mythical period of Mesopotamian origin was used; third, the history itself of his relationships with the Phocaean sailors, in which a narrative clich. was employed, and finally the likely origin of his own name, maybe taken perhaps by Charon of Lampsacus from a Bithynian mythological cycle.Los aspectos m.ticos de la figura de Argantonio, manifestación del buen monarca acogedor del viajero y expresión de la idea de fuente de riqueza lejana y misteriosa; la base mítica de su cronología vital, determinada por la aplicación de un módulo cronológico mítico de origen mesopotámico integrado en el acervo mítico griego, la utilización de un verdadero cliché narrativo para contar la historia de sus relaciones con los marinos foceos y el probable origen de su propio nombre, quizá tomado por Caronte de Lámpsaco de un ciclo mitolígico bitinio, permiten poner muy en duda la historicidad de este personaje.

    Full Text Available El presente artículo tiene por objetivo analizar las prácticas de resolución de conflictos domésticos de las mujeres ante la justicia en los Partidos de Quillota, Aconcagua y Santiago entre 1800 y 1850, a través de la revisión de juicios civiles por pensión de alimentos entablados por mujeres casadas y solas. El periodo a analizar representa un proceso de legitimación de un régimen jurídico institucional. No obstante, las prácticas de resolución de conflictos estuvieron acompañadas de prácticas fronterizas, donde la ley y la costumbre estuvieron en permanente dialogo. En este contexto, proponemos que las mujeres recurrieron a la justicia institucional reclamando protección masculina para ellas y sus hijos, como parte de un sinfín de estrategias que se enmarcaban dentro de la justicia negociada, lo cual implicó, por parte de éstas, un desarrollo de estrategias que involucraron la resistencia de género, cultura jurídica y la publicidad del conflicto. De esto, distinguimos que las mujeres casadas, amparadas por la institución matrimonial, impulsaron estrategias apegadas a los ideales hegemónicos asegurando una pensión que correspondiera a sus necesidades. En cambio, las mujeres solas tuvieron que recurrir a estrategias más amplias y fronterizas que comprometía la solidaridad de sus cercanos, la divulgación del conflicto y  el honor femenino.

    Full Text Available O direito à saúde é um direito fundamental, conquistado por meio da participação social que resultou em sua inserção na atual Constituição Federal, e na instituição do SUS. Este estudo objetivou analisar a percepção dos usuários do SUS, no Distrito Federal, sobre o direito à saúde e o impacto desse entendimento na dinâmica da construção do sistema. Foram realizadas entrevistas, com 75 usuários, entre setembro e outubro de 2014. Como roteiro de pesquisa utilizou-se o método qualiquantitativo de abordagem descritiva exploratória. Os dados coletados, através de formulário semiestruturado, foram tratados com sistema planilhas do Microsoft Office Excel versão 2010 e para auxiliar a pergunta aberta utilizou-se a técnica do Discurso do Sujeito Coletivo (DSC. Os tópicos de interesse foram: o conceito de saúde, o SUS, informação em saúde e participação social. Verificou-se, portanto, que a maioria dos usuários do SUS não reconhece a saúde como direito. O entendimento de SUS como política criada para garantir o direito à saúde é substituído pela ideia de concessão do Estado. Aliado à isso, o desconhecimento das leis de saúde, a falta de consciência sanitária e a sensação de resignação e submissão de sua situação de saúde reforçam este pensamento. O impacto desse entendimento na dinâmica da construção do sistema acontece pela baixa capacidade de organização e pouco conhecimento e participação no Conselho de Saúde. Foi possível concluir que o desconhecimento do direito à saúde compromete e enfraquece o processo de desenvolvimento do SUS, que se fundamenta no princípio da participação e controle social.

    2014-10-15

    Highlights: • The micro hardness of weld metal in F82H/SUS316L joint partially decreases after PWHT by shifting beam position to SUS316L. • Charpy impact energy of F82H/SUS316L joint obviously increases after PWHT due to the release of residual stress. • The tensile strength of weld metal in F82H/SUS316L joint is higher than that of SUS316L. • The fiber laser welding seems to be one of the most candidate methods to join between F82H and SUS316L pipes practically. - Abstract: A dissimilar butt-joint between reduced activation ferritic/martensitic steel F82H and SUS316L austenitic stainless steel was made by 4 kW fiber laser and the influence of laser beam position on its mechanical properties before and after post-weld heat treatment (PWHT) was examined at room temperature. From the nano-indentation measurements and the microstructural observations, it is found that the micro hardness of weld metal partially decreases after PWHT by shifting beam position to SUS316L because its phase seems to move from only the martensitic phase to the mixture of austenitic and martensitic phases. In addition, Charpy impact test suggests that the impact energy slightly increases by shifting beam position before PWHT and obviously increases after PWHT due to the release of residual stress. Moreover, the tensile test indicates that the tensile strength of weld metal is higher than that of SUS316L and the fracture occurs at the base metal of SUS316L regardless of laser beam position.

    Full Text Available The aim of this study was to analyze the role of teaching at primary healthcare services within the Brazilian National Health System (SUS in dentists' training, at a public university in the south of Brazil. A qualitative methodological approach (case study was used. Interviews were conducted with 12 dentistry students, six dentists who were preceptors working in public primary healthcare services and three teachers connected with this curricular training. Our findings showed that the curricular training in SUS primary healthcare services had an impact on the dentists' education through establishment of bonds, autonomy in problem-solving and multiprofessional teamwork. It was seen that they learned about how healthcare services function, about healthcare and about development of cultural competence. There is a need to maintain constant questioning regarding these practices, and to ensure the presence of infrastructure and qualified professionals for teaching at these services.

    Full Text Available Aún hoy, en plena sociedad del conocimiento, se tienen límites conceptuales en relación con aspectos tan fundamentales como la identidad, la imagen y la reputación de marca. Incluso donde mayores dificultades se presentan es en las posibilidades de evaluación y medición de cada uno de estos conceptos ligados con la reputación empresarial. Así, la marca, como el elemento fundamental de las empresas del presente siglo, se ve obligada a indagar nuevas formas de interpretar sus acciones estratégicas, con el único objetivo de continuar conformando la estructura de la marca, el ADN que la diferencia y que le permite contrastar sus resultados a partir de evaluaciones y mediciones fiables, en un contexto donde la transparencia, ante el alud de comunicación, se plantea casi como una exigencia.

    Estado, sociedad, Derecho, juridicidad. Se trata de los principales conceptos que preocupan las corrientes idealistas alemanas y, en un segundo momento, las corrientes neo idealistas italianas. Siguiendo la estela de Hegel, Gentile y Croce, son los dos grandes pensadores italianos que han querido presentar el Estado como autentica categoría espiritual. Entre el 1940 y el 1970, en Italia, aparecen una serie de autores que, sin abandonar del todo sus originarias posturas, pretenderán ¿depurar¿ ...

    At moderately high temperature sections of Advanced Ultra Super Critical (AUSC) boilers, welding of superalloys to austenitic steels is inevitable owing to economic aspects of boiler. Welding of SUS 304H and Inconel 617 (IN 617) was attempted using IN 617 filler material employing conventional Gas Tungsten Arc Welding (GTAW) process and the procedure was successfully established along with optimized welding parameters. Microstructural characterization was carried out to identify various zones on either side of the fusion boundaries. Unmixed Zone and Heat Affected Zone (HAZ) were observed towards SUS 304H fusion boundary while no distinct HAZ was observed towards IN 617 fusion boundary. Micro-hardness profiling indicated decrease in hardness at the HAZ towards SUS 304H fusion boundary. Mechanical properties evaluation at both ambient and elevated temperatures was carried out and data obtained was compared with those of base metals. The tensile strength of the cross weld specimens at high temperatures were observed to be marginally lower than that of IN 617 but significantly more than that of SUS 304H, hence, tolerable. Stress-rupture properties of the cross-weld specimens as tested in this study were found to be intermediate to the base metals’ data, thus, suitable for AUSC power plants' boiler applications. Hence, this work gives an insight into welding procedure establishment, microstructural development, variation of mechanical properties at elevated temperatures and stress-rupture properties of the dissimilar metal welds at elevated temperatures. - Highlights: • Procedure establishment & parameters optimization for fabricating defect-free welds. • Characterization of various zones formed during welding. • Mechanical properties evaluation and comparison with those of base metals. • Influence of various zones formed during welding on mechanical properties inferred. • Understanding long term behavior of welds at elevated temperatures
