Synthesis and Characterization of Zn(acac)2 One-dimensional Nanostructures by Novel Method

In this work we have sublimated bulk Zn(acac)2 at different temperatures and the effect of sublimation temperature on the morphology of product was investigated. Nanostructures were characterized by means of SEM, XRD and FT-IR

Synthesis and Characterization of Silver Choromate Nanostructures via a Simple Precipitation Method

In summary, Ag2CrO4 nanostructures were prepared via a simple precipitation method by using [Ag(HSal)] as a new silver precursor. According to SEM images, the morphology of silver chromate nanostructures was 1-D and 3-D by using [Ag(HSal)] and AgNO3, respectively. Besides, SDS molecules were applied to decrease the particle size of the assynthesized products.

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

A wandering spleen presenting as a pelvic mass: case report and review of the literature

Wandering spleens are rare clinical entities found more commonly in females. We report a young female patient found to harbour a pelvic spleen. The literature regarding this rare ectopia is reviewed. The wandering spleen should be considered in the differential diagnosis of pelvic masses

Very Preterm Early Motor Repertoire and Neurodevelopmental Outcomes at 8 Years

BACKGROUND AND OBJECTIVES: Children born very preterm (<32 weeks' gestation) have more neurodevelopmental problems compared with term-born peers. Aberrant fidgety movements (FMs) are associated with adverse motor outcomes in children born very preterm. However, associations of aberrant FMs combined with additional movements and postures to give a motor optimality score-revised (MOS-R) with school-aged cognitive and motor outcomes are unclear. Our aim with this study was to determine those associations. METHODS: Of 118 infants born <30 weeks' gestation recruited into a randomized controlled trial of early intervention, 97 had a general movements assessment at 3 months' corrected age and were eligible for this study. Early motor repertoire including FMs and MOS-R were scored from videos of infant's spontaneous movement at 3 months' corrected age. At 8 years' corrected age, cognitive and motor performances were evaluated. Associations of early FMs and MOS-R with outcomes at 8 years were determined using linear regression. RESULTS: Seventy-eight (80%) infants with early motor repertoire data had neurodevelopmental assessments at 8 years. A higher MOS-R, and favorable components of the individual subscales of the MOS-R, including the presence of normal FMs, were associated with better performance for general cognition, attention, working memory, executive function and motor function at 8 years; eg, presence of normal FMs was associated with a 21.6 points higher general conceptual ability score (95% confidence interval: 12.8-30.5; P < .001) compared with absent FMs. CONCLUSIONS: Favorable early motor repertoire of infants born <30 weeks is strongly associated with improved cognitive and motor performance at 8 years

Favorable parental perception of behaviour at two years' corrected age in very preterm-born children

Problems in behavioural and emotional outcome are amongst the long-term sequelae of preterm birth. The exact prevalence and associations with perinatal risk factors are unknown. Minimal research has been performed in pre-school aged children, compared to school age. The primary aim of this study was to determine the prevalence of parent-reported behavioural and emotional problems at the age of two in children born at less than 30 weeks' gestational age and/or birth weight less than 1000 g. The secondary aim was to determine whether perinatal factors were associated with the behavioural and emotional outcome. Perinatal characteristics of 144 preterm-born children from the NeoLiFeS cohort were collected retrospectively. Of these children, 101 parents filled out a Childs Behaviour Checklist (CBCL) at the corrected age of two. The results of the CBCL tests were presented as Z-scores, a Z-score of 0 indicating the mean of behavioural scores in the norm population. A Z-score higher than zero indicates less behavioural problems than average, a negative Z-score indicates more problems. Associations between perinatal risk factors and CBCL-scores were analysed using linear regression analyses. Prevalences of clinically relevant CBCL scores were low, 4%, 2% and 5% for total score, internalizing score or externalizing score, respectively. Being part of a twin was associated with higher internalizing Z-scores, indicating less problems in emotional behaviour. Bronchopulmonary dysplasia was associated with lower Z-scores in total and externalizing behaviour. In conclusion, in our cohort generally very few problems in behavioural and emotional outcome were reported at the age of two
