Five Little Monkeys Jumping on the Bed : En litteraturstudie om hur arbete med sång, rim och ramsor kan främja barns utveckling av engelska som främmande språk i grundskolans tidigare år.

Syftet med litteraturstudien är att undersöka hur arbete med sång, rim och ramsor kan främja yngre elevers språkutveckling i engelska som främmande språk. Detta görs genom att fokusera på främjandet av barns språkinlärning, hur lärare bör arbeta med sång, rim och ramsor inom engelska som främmande språk, samt lärares attityder till ett sådant arbetssätt. Arbetet genomfördes som en systematisk litteraturstudie innehållande en bakgrund med relevant teori, samt analys av fem vetenskapliga studier rörande ämnet. Dessa gav möjlighet till en bred bild av området, då länder och perspektiv varierade. Studierna valdes ut genom sökning i databaser efter relevans och tillförlitlighet. I studiernas resultat framgick att majoriteten av tillfrågade lärare och elever var positivt inställda till arbete med sång och ramsor i engelskundervisning, och den språkutveckling dessa metoder innebar. Genom arbete med läraren som förebild motiverades eleverna. Dock fanns en avsaknad av material och kunskap för att kunna genomföra och bedöma undervisning innehållande sång och ramsor. En avsaknad av rim i de studier som analyserats berörs även i studien, likaså en brist på svenska studier. Sammanfattningsvis verkar sång och ramsor enligt de granskade studierna ha ett värde i engelskundervisning. Dock finns det behov av mer forskning och kunskap för att få starkare underlag för användning av dessa metoder i undervisning.

Modelagem e simulação de um reator trickle-bed para hidrogenação de propeno

Neste trabalho foi modelado um reator catalítico heterogêneo, pressurizado, adiabático e provido de reciclo. O leito deste reator está dividido em duas partes, sendo que a primeira opera como um reator trickle-bed, enquanto a segunda opera como um reator de leito fixo, onde os regentes estão em fase líquida. Um Sistema de Hidrogenação de Propeno em operação no Pólo Petroquímico do Sul foi utilizado para fornecer os dados necessários à validação do modelo proposto. Neste sistema, a reação de hidrogenação de propeno, em fase líquida, ocorre sobre um catalisador níquel/óxido de níquel. Uma equação, que representa a taxa da reação no intervalo de temperatura de interesse para o sistema, foi desenvolvida utilizando-se dados experimentais obtidos em um reator batelada. O comportamento termodinâmico foi representado através de dados de equilíbrio do sistema binário hidrogênio-propano. Considerou-se que a fase líquida escoa em plug-flow e a fase gasosa, devido à existência de um selo líquido no interior do reator, foi considerada estagnada.

Qualidade da assistência e o conhecimento sobre o direito à saúde das pessoas com úlcera venosa crônica

The study aimed to identify the quality of care and knowledge of health rights of people with chronic venous ulcers (VU) in Brasilian National Health Care System (SUS). It is a cross-sectional study, with quantitative approach, performed at the University Hospital Onofre Lopes (HUOL). The study was approved by the Ethics Committee of HUOL (CAAE nº 0148.0.051.000-10). The sample by accessibility was composed for 30 people with VU treated at the outpatient surgical clinic of HUOL. For data collection we used a structured questionnaire composed of two parts: sociodemographic characteristics and of health, of care and the clinical course of VU; and knowledge of people with VU about the rights of health. The results were processed using SPSS 15.0 and analyzed by descriptive statistics. Given the characterizations sociodemographic and health presented, we identified a clientele of users with VU predominantly female (76,7%), aged from 60 years (66,7%), married/ stable union (60,0%), low education level (83,3%), family income lower than a minimum wage (73,3%), unemployeds and with chronic diseases (53,3%), sleep greater than or equal to 6 hours (76,7%) and were not alcoholics or smokers (93,3%). In relation to clinical conditions, were shown the presence of one or more relapses of VU (73,3%), predominance of granulation tissue/epithelialization in the bed of VU (60,0%), exudate serosanguineous (43,3%), in quantity medium/large (60,0%), with no predominance of presence or absence of odor (50,0%), all patients with tissue loss in grade III / IV, no signs of infection (73,3%) and presence of intense pain (50,0%). In the last 30 days the main venue of achievement of dressing was the HUOL (100,0%), the main compression therapy used was the Unna boot (60,0%) and on inability to perform the dressing on the unit were the own patients who made the exchange at home (40,0%). The majority of respondents listed out more positive factors associated with quality of care (56,7%) were satisfied with the care of SUS (76,7%), claimed to have knowledge about their rights (70,0%), but at the same time did not know the meaning of the acronym SUS (90,0%) and classified their level of information as inappropriate (70,0%). We realize that people with VU identified as good the quality of care and demonstrated inadequate knowledge about their rights to health in the SUS, but showed interest in acquiring more information. The basic rights to entry in the SUS are constitutionally guaranteed and need to be disseminated in order to make them known to the population, so it can be implemented and ensured a greater resolution assistance in treating this type of injury

Treatment of venous ulcers with fibrin sealant derived from snake venom

Venous ulcers of the lower limbs complicated by infection or chronicity represent a serious public health problem. The elevated number of those afflicted burdens the health services, interferes in quality of life and causes absenteeism. Although there are 2,500 items on the market, ranging from the simplest dressing up to the most complex types of dressing, treatment remains a challenge. Among the substances used, fibrin sealant is the one that promotes diminution of bacterial colonization and of edema, controls hemorrhaging, alters the pain threshold by protecting the nerve endings, hydrates the wound bed and forms granulation tissue that favors healing. Its disadvantages include higher cost and utilization of human fibrinogen that can transmit infectious diseases. The Center for the Study of Venoms and Venomous Animals (CEVAP) at São Paulo State University (UNESP) developed a new sealant made up of fibrinogen extracted from large animals and from an enzyme obtained from snake venom. The present study, developed in the Health Education Clinic (CEPS) of Sacred Heart University (USC) aimed to evaluate the effect of the new sealant on the healing process of venous ulcers in 24 adult patients, seven of whom were male and 17 female. Two study groups were formed as follows: Group 1 (G1) - control group of 11 patients treated with essential fatty acid (EFA) and Unna's boot, and Group 2 (G2) - 13 patients treated with essential fatty acid (EFA), fibrin sealant and Unna's boot. The follow-up lasted eight weeks and the sealant was applied at only the first and fourth weeks. The results showed that Group 2 presented worse lesion conditions as to healing, but, when comparing the two groups, it was noteworthy that the the sealant was effective in healing venous ulcers. There is evidence that the new sealant is recommended for leg ulcers with the following advantages: ease of application, preparation of the wound bed, diminution of pain and a higher number of discharges in the eighth week. More important, other positive characteristics are non-transmission of infectious diseases, absence of adverse reactions, and economic advantage of being produced by Brazilian technology. Finally, it is suggested that the weekly application of sealant, for at least eight weeks, could improve the healing process and consequently life quality.

Biosorption and desorption of lanthanum(III) and neodymium(III) in fixed-bed columns with Sargassum sp.: Perspectives for separation of rare earth metals

Rare earth (RE) metals are essentials for the manufacturing of high-technology products. The separation of RE is complex and expensive; biosorption is an alternative to conventional processes. This work focuses on the biosorption of monocomponent and bicomponent solutions of lanthanum(III) and neodymium(III) in fixed-bed columns using Sargassum sp. biomass. The desorption of metals with HCl 0.10 mol L-1 from loaded biomass is also carried out with the objective of increasing the efficiency of metal separation. Simple models have been successfully used to model breakthrough curves (i.e., Thomas, Bohart-Adams, and Yoon-Nelson equations) for the biosorption of monocomponent solutions. From biosorption and desorption experiments in both monocomponent and bicomponent solutions, a slight selectivity of the biomass for Nd(III) over La(III) is observed. The experiments did not find an effective separation of the RE studied, but their results indicate a possible partition between the metals, which is the fundamental condition for separation perspectives.

OBJETIVO: Comparar a cola de fibrina (Tissucol®) e o plasma rico em plaquetas em enxertos cutâneos de espessura completa em malha em cães. MÉTODOS: Foram utilizados 18 cães, distribuídos em dois grupos, cola de fibrina (CF) e plasma rico em plaquetas (PRP). em todos os animais foi realizado um enxerto cutâneo de 3x3 cm, em malha de espessura completa. No membro esquerdo foi colocado o biomaterial entre o enxerto e o leito receptor, cada qual em seu grupo, o membro direito serviu como grupo controle. Todos os animais foram avaliados clinicamente a cada 48 horas até o décimo quarto dia, através das variáveis: exsudação, coloração, edema e aspecto cosmético; histologicamente em três animais, no terceiro, sétimo e décimo quarto dia de pós-operatório através das variáveis: fibroblastos, colágeno, tecido de granulação, integração-aderência microscópica e inflamação aguda. RESULTADOS: Avaliações clínicas demonstraram que o grupo CF apresentou melhor escores em todas variáveis quando comparado com o grupo PRP. Nas avaliações histológicas o grupo PRP apresentou maior presença de fibroblastos ao sétimo e décimo quarto dia. CONCLUSÃO: A cola de fibrina foi clinicamente superior ao grupo plasma rico em plaquetas quando usados em enxertos cutâneos de espessura completa em cães.

Fluid dynamics of air in a packed bed: velocity profiles and the continuum model assumption

Air flow through packed beds was analyzed experimentally under conditions ranging from those that reinforce the effect of the wall on the void fraction to those that minimize it. The packing was spherical particles, with a tube-to-particle diameter ratio (D/dp) between 3 and 60. Air flow rates were maintained between 1.3 and 4.44 m3/min, and gas velocity was measured with a Pitot tube positioned above the bed exit. Measurements were made at various radial and angular coordinate values, allowing the distribution of air flow across the bed to be described in detail. Comparison of the experimentally observed radial profiles with those derived from published equations revealed that at high D/dp ratios the measured and calculated velocity profiles behaved similarly. At low ratios, oscillations in the velocity profiles agreed with those in the voidage profiles, signifying that treating the porous medium as a continuum medium is questionable in these cases.
