Evaluating the resistance to sunn pest (Eurygaster integriceps Put) and its relationship with high-molecular-weight glutenin subunit in wheat
Trabalho final de mestrado integrado em Medicina, apresentado à Faculdade de Medicina da Universidade de Coimbra.Em consequência de um fenómeno global de envelhecimento populacional, é expectável um aumento na prevalência de demência. A demência vascular é a segunda causa mais comum de demência, depois da doença de Alzheimer. Trata-se de uma entidade clínica bastante heterogénea, sendo o acidente vascular cerebral (AVC) um dos seus mecanismos subjacentes. No entanto, nem todos os doentes desenvolvem demência após AVC, e nem sempre ela é do tipo vascular. Idade avançada, características do AVC, as suas complicações, e evidências neuro-imagiológicas de lesão cerebral acrescida, parecem determinar o desenvolvimento de demência. Evitar a recorrência do AVC, através do controlo de fatores de risco vasculares é, por enquanto, a única forma reconhecida de prevenção.As people live longer, an increase in prevalence and burden of dementia is to be expected worldwide. Vascular dementia is the second most common cause of dementia, second to Alzheimer’s disease. It is a heterogeneous clinical entity, with stroke being one of the responsible mechanisms. However, not all stroke patients develop dementia, and not always in the vascular form. Older age, stroke-related factors, its complications and other neuroimaging changes, seem to determine the occurrence of dementia after a stroke. Avoiding recurrence of stroke by careful monitoring and treatment of vascular risk factors is, for now, the only recognized preventive strategy of poststroke dementia
Determination of relationship between HMW glutenin subunits and bread making quality in bread wheat
Screening of drought-tolerant and sensitive genotypes in soybean (Glycine max L.) using different multivariate methods
The soybean is a crop of global importance, which cultivate in worldwide. However, the soybean is more susceptible to water shortages during germination and reproductive growth stages. Stress is an in ordinary physical process of environmental factors effects and it has traumatic ability, which causes unusual metabolism in plants, and it is possible; reduce plant product or causes plant death. Drought indices provide a measure of drought based on loss of yield under drought conditions in comparison to normal and have been used for screening drought tolerant genotypes. We cultivated Ten genotypes of soybean in the research field of seed and plant improvement institute in Karaj- Iran in 2015 June. The experimental design was a randomized block with three replicate in two separate field experiments for normal and stress conditions. We irrigated the normal experiment in 85% field capacity and got 50% filed capacity for stress conditions. Seventeen drought tolerance indices were calculated. Four methods were used to identify more resistant and more susceptible genotypes. After genotypes selection, we carried out experiment in green house with two selected genotypes. Results showed using the indices such as MP, GMP and STI, alone, cannot select a stable genotype and we have to use a combine of all indices or use indices that showed reduction and average yield, together. In second year, results showed that we had a true selection.Int. J. Agril. Res. Innov. & Tech. 7 (2): 7-17, December, 201
Determination of relationship between HMW glutenin subunits and bread making quality in bread wheat
Dissertação de mestrado em Contabilidade e Finanças (Auditoria), apresentada à Faculdade de Economia da Universidade de Coimbra, sob a orientação de José Manuel Bernardo Vaz Ferreira.Este estudo tem como objetivo analisar a situação das empresas da Região
Autónoma da Madeira no difícil contexto atual. As falências nas empresas têm acontecido
com regularidade, devido às diversas alterações conjunturais, que provocam mudanças no
contexto do sistema de controlo interno.
Este estudo foi realizado com o objetivo de verificar se os procedimentos do
controlo interno estão a ser aplicados corretamente nas empresas madeirenses e verificar se
as empresas estão fragilizadas devido às condições atuais que o país atravessa, mais
concretamente na situação desta região insular que, no ano de 2011 sofreu um aumento do
IVA (Imposto sobre o Valor Acrescentado) em seis pontos percentuais. Deste modo, este
estudo pretende verificar os pontos fracos do controlo interno em concordância com outros
três fatores externos (pagamentos por parte do Estado às empresas, aumento do IVA para
22% e aparecimento de novas superfícies/concorrência).
Os resultados do estudo revelam que as empresas da Madeira ainda cometem
algumas falhas no controlo interno, de natureza multifatorial. Em relação ao Estado, este
tem um papel pouco significativo na situação das empresas (17,2%), o mesmo não
sucedendo com o impacto do aumento do IVA, já que, cerca de 96,9% das empresas referem
que os clientes estão a consumir menos, o que é preocupante. Em resultado desta situação,
26,7% da amostra coloca em hipótese a falência associada a este último fator. No que diz
respeito à concorrência, os resultados demonstram que metade (50%) das empresas
inquiridas, sentiram um impacto negativo no seu negócio após a entrada das grandes
superfícies na Região.
Por último, as empresas madeirenses, neste momento, sofrem um forte impacto de
componentes externos ao controlo interno, sendo necessária uma reestruturação,
essencialmente no IVA
