Maskulinitet i Midgård : En kvalitativ filmanalys av manligagymnasieelevers favoritfilm

Syftet med denna uppsats är att visa hur maskulinitet gestaltas i filmtrilogin Härskarringen och att undersöka huruvida karaktärerna är nyskapande eller stereotypa. Härskarringen valdes ut i samband med en större undersökning bland manliga gymnasieelever. Vi använder oss av en kvalitativ analys av de tre filmerna. I Härskarringen presenteras en stereotyp bild av maskulinitet där typiska manliga karaktärsdrag är att vara ädel, fysiskt stark, modig, lojal, ödmjuk, potent, intelligent, beskyddande, respektingivande och med en stark vilja att kämpa för det rätta.

Förändrade intimitetsformer bland äldre i det senmoderna samhället

Changing forms of intimacy among older people in late modern society The purpose of this paper is to draw attention to a neglected reality in Swedish social research: New romantic relationships in later life. Our theoretical points of departure are the transformation of intimacy and the transition from a culture of marriage to a culture of divorce. We ask if the transformation of intimacy has reached later life and investigate late life divorce, attitudes to and choice of union form in late life heterosexual relationships, relationship history and the importance of a relationship for life satisfaction. The results, which are based both on demographic data and a survey to 60–90 year old Swedes (n=1225), show that changing relationship patterns in late modern Sweden have reached older people. In romantic relationships initiated in later life LAT is the preferred union form, followed by cohabitation, while marriage is a rare choice. In some respects this makes older people an avant-garde in the investigation of alternative union forms. The results also show the importance of romantic relationships for life satisfaction in later life – independent of union form. Finally we criticize Swedish census data, which is based on civil status, for giving a somewhat distorted image of older people’s family and romantic lives.

The position effect of structural Eucalyptus round timber on the flexural modulus of elasticity

A madeira roliça possui grande emprego nas construções civis, desempenhando a função de vigas, colunas, fundações, postes para distribuição de energia elétrica, entre outras, apresentando a vantagem de não ser processada, como é o caso da madeira serrada. O projeto envolvendo elementos roliços requer, além de outras variáveis estruturais, o conhecimento do módulo de elasticidade. No Brasil, os documentos normativos que tratam da determinação das propriedades de rigidez e resistência para peças roliças de madeira estão em vigência há mais de vinte anos sem revisão técnica. A madeira roliça, por geralmente possuir eixo com curvatura não nula, pode apresentar, segundo a posição da peça no ensaio de flexão, valores diferentes do módulo de elasticidade. Este trabalho tem como objetivo analisara influência da posição de peças roliças de madeira de Eucalyptus grandis na determinação do módulo de elasticidade na flexão. O ensaio de flexão utilizado é o de três pontos, sendo cada peça avaliada em duas posições distintas, definidas mediante o giro da seção transversal em torno do eixo. Os resultados encontrados indicam a necessidade do ensaio de flexão em, pelo menos, duas posições distintas da peça.

Efeitos genéticos e ambientais sobre a idade à primeira concepção de fêmeas suínas

The genetic and environmental factors that affect age at first conception (AFC) of gilts were evaluated, using 466 observations of Dalland animals (C-40). The software program MTDFREML was used to assess the genetic parameters on an animal model that included as fixed effect, contemporary group and, as random effects, the additive genetic, the common litter and the error. Mean value of AFC was 241.12±25.9 days, with CV of 8.5 %. Variance analysis showed that year (P<0.01), season (P<0.01) and herd effects (P<0.01) were important sources of variation of AFC. The throat effect (P=0.34) was not important for the AFC, but the mother of the gilts (P<0.01) was an important source of variation. The heritability estimate was 0.44±0.14 that this trait would yield genetic gain as a response to the selection.

Estudo do efeito do óxido de bário no comportamento de massas para porcelanato

In this work, it is proposed the study of the effect of barium oxide acting as synthetic flow in the behavior of masses for stoneware from the use of raw materials found in the deposits of minerals of the Rio Grande do Norte that it makes use of a great natural potential for the industrialization of the product. The porcelanato is a sophisticated product with excellent final properties being applied as ceramic coating in buildings of high standard of engineering. The raw materials selected for the development of the study had been two types of argilas, two types of feldspatos, dolomita, talco, barium carbonate and silica, being characterized by X-ray fluorescence, X-ray diffraction, granulometric analysis, dilatometric analysis and thermal analysis. Thus, it is intended to define four formulations using the cited raw materials that will be processed, conformed and sintered in the temperatures of 1150 °C, 1175 °C, 1200 °C, 1225 °C e 1250 °C. From the physical characterizations, chemical and morphologic of the formed formulations, the effect of barium oxide is determined in the physical and mechanical properties of the studied system carrying water absorption tests, linear retraction, apparent porosity, apparent specific mass, compacting curve, flexural strength and microstructural analysis by XRD and SEM. After analyzing the results, indicated that barium oxide acts as a flux of high temperature and as the ordering of structure, where the embedded glass phase has the nucleating effect phase potassium silico-aluminum reacting with free silica which together with the high content of potassium concentrated form a new crystalline phase called microcline. The masses studied with the addition of barium oxide present physical-mechanical properties highly satisfactory in reduced firing temperatures, which implies a saving in energy given off in the production and increased productivity

Ileal mucosal mast cell, eosinophil, and goblet cell populations during Hymenolepis diminuta infection of the rat

The population dynamics in the enteric connective tissues of eosinophils, mucosal mast cells (MMC), and in the mucosal epithelium of goblet cells were examined morphometrically in fixed ileal tissue of outbred Sprague Dawley rats during the first 32 days of infection with the tapeworm Hymenolepis diminuta. MMC and eosinophils were present in the lamina propria and submucosa; however, only eosinophils were also present in the muscularis externa. Eosinophilic infiltrate was first observed in the lamina propria at 15 days postinfection (dpi) and the numbers of eosinophils remained elevated through 32 dpi. Initial mucosal mastocytosis was detected on 6 dpi and MC numbers continued to rise over the study period without reaching a plateau. Goblet cell hyperplasia occurred only at 32 dpi. In contrast to some intestinal nematode infections where these same 3 cell types are associated with the host's expulsion responses, H. diminuta is not lost by a rapid host response in the outbred Sprague Dawley rat strain used in these experiments. We suggest that either the induction of hyperplasia of these host effector cells in ileum tissue during H. diminuta infection is not capable of triggering parasite rejection mechanisms, or the function of the induced hyperplasia is necessary for some as yet unassociated physiological or tissue architecture change in the host's intestine.

Comparison of decompressive surgery, electroacupuncture, and decompressive surgery followed by electroacupuncture for the treatment of dogs with intervertebral disk disease with long-standing severe neurologic deficits

Objective To compare the effects of decompressive surgery (DSX), electroacupuncture (EAP), and DSX followed by EAP (DSX + EAP) for the treatment of thoracolumbar intervertebral disk disease (IVDD) in dogs with severe neurologic deficits of > 48 hours' duration.Design Retrospective case series and prospective clinical trial.Animals-40 dogs between 3 and 6 yEAPs old and weighing between 10 and 20 kg (22 and 44 lb) with long-standing (>48 hours) clinical signs of severe neurologic disease attributable to thoracolumbar IVDD.Procedures Thoracolumbar medullar injury was classified on the basis of neurologic signs by use of a scale ranging from 1 (least severe) to 5 (most severe). The DSX dogs (n = 10) were retrospectively selected from those that underwent DSX for the treatment of thoracolumbar IVDD. In addition, 19 dogs received EAP alone and 11 dogs underwent DSX followed by EAP (DSX + EAP). Outcome was considered a clinical success when a dog initially classified as grade 4 or 5 was classified as grade 1 or 2 within 6 months after the end of treatment.Results The proportion of dogs with clinical success was significantly higher for dogs that underwent EAP (15/19) than for dogs that underwent DSX (4/10); the proportion of dogs with clinical success for dogs that underwent DSX + EAP was intermediate (8/11).Conclusions and Clinical Relevance EAP was more effective than DSX for recovery of ambulation and improvement in neurologic deficits in dogs with long-standing severe deficits attributable to thoracolumbar IVDD.

A case of Zimmermann-Laband syndrome with supernumerary teeth

Background: Zimmermann-Laband syndrome is a rare autosomal dominant disorder that is characterized by gingival fibromatosis, ear, nose, bone, and nail defects, and hepatosplenomegaly.Methods: This case report describes the clinical presentation and periodontal findings in a 13-year-old female patient with previously undiagnosed Zimmermann-Laband syndrome.Results: Clinical and radiographic findings and genetic counseling confirmed the diagnosis of Zimmermann-Laband syndrome. The most striking oral findings were the presence of gingival enlargement involving both the maxillary and mandibular arches, anterior open bite, non-erupted teeth, and two supernumerary teeth. Periodontal treatment consisted of gingivectomy in four quadrants. Histopathologic evaluation of excised tissue supported the diagnosis of gingival fibromatosis. The patient was referred for appropriate orthodontic treatment and genetic counseling, and has been closely followed for the earliest signs of hepatosplenomegaly.Conclusions: Dental practitioners should be alert for developmental abnormalities that may occur in patients with gingival fibromatosis as this may indicate the presence of a rare disorder like Zimmermann-Laband syndrome. A comprehensive medical history and physical systemic evaluation are essential for correct diagnosis and treatment of these cases.

MOMO syndrome associated with autism: a case report

This is a case report of macrosomia, obesity, macrocephaly and ocular abnormalities (MOMO syndrome) associated with autism. Studies on genetic or environmental syndromes associated with autism can provide genetic markers or uncover relevant events, and are very important for the definition of autism subgroups in future molecular research.

Evaluation of antimutagenic activity and mechanisms of action of beta-glucan from barley, in CHO-k1 and HTC cell lines using the micronucleus test

Due to the need to identify new antimutagenic agents and to determine their mechanism of action, the present study examined the mechanism of action of the P-glucan with regard to antimutagenicity using the micronucleus assay in CHO-kl and HTC cell lines. The mutagenicity experiments were performed with three different concentrations of P-glucan (5, 10, and 20 mu g/mL), in wich only the highest dose showed mutagenic activity. In the antimutagenicity experiments, the same concentrations of P-glucan were combined with a mutagenic agent, methylmethane sulfonate, or 2-aminoanthracene, using four different treatment protocols: pre-treatment, simultaneous treatment (simple and with pre-incubation), and post-treatment. The results indicate that the CHO-kl cell line treated with MMS presented a chemopreventive activity for all the doses of P-glucan in the different treatment protocols, except for the lowest dose in post-treatment. When HTC cell line treated with MMS is analysed, a chemopreventive activity can be verified for the highest dose in both pre- and post-treatment. For the simple simultaneous treatment, the three doses demonstrated efficacy, while for the simultaneous treatment with pre-incubation only the intermediate concentration was effective. In HTC treated with 2AA both the lowest dose in the pre-treatment protocol and the post-treatment protocol did not show efficacy in preventing DNA damage. The evaluation of the different protocols and the damage decrease percentages observed suggest that P-glucan has both desmutagenic and bioantimutagenic activity. It is necessary, however, to note that efficacy and mechanism of action are subject to variation when compared the two cell lines, since in HTC, representing a drug-metabolizing system, this substance can show a diminished chemopreventive capacity.
