Em Portugal, assim como um pouco por todo o mundo, a maioria das empresas são de cariz familiar. A predominância destas empresas faz com que as mesmas tenham um papel relevante na economia, seja pela criação e distribuição de riqueza seja pela criação de emprego. A importância que se lhes reconhece constituiu o fator ou motivação suficiente para desenvolver este trabalho que, com base numa metodologia preferencialmente quantitativa, aplicada a um conjunto de empresas familiares associadas da Associação Portuguesa das Empresas Familiares, se propõe averiguar se estas empresas atribuem importância à informação financeira no processo da tomada de decisão. Utilizou-se como instrumento de recolha de informação um inquérito por questionário e cujos resultados permitiram desenvolver uma análise descritiva exploratória e aplicar testes estatísticos não paramétricos. O trabalho realizado permitiu recolher evidência suficiente para concluir sobre a importância das demonstrações financeiras para o processo de tomada de decisão, em particular no que respeita à utilização do balanço e da demonstração dos resultados. Não foi, porém, possível identificar um padrão sobre as demonstrações financeiras preparadas em função do tipo de norma contabilística aplicável e do setor de atividade, nem sobre a importância atribuída à informação financeira em função da dimensão da empresa. Foi possível concluir que a informação financeira é, fundamentalmente, utilizada para avaliar os impactos financeiros, apoiar na gestão corrente, tomar decisões de investimento e cumprir com obrigações fiscais, sendo muito evidente a importância que as empresas familiares atribuem à informação financeira como forma de dar cumprimento às obrigações fiscais.

A Feasibility Study Of Fricke Dosimetry As An Absorbed Dose To Water Standard For 192ir Hdr Sources.
Resumo:
High dose rate brachytherapy (HDR) using 192Ir sources is well accepted as an important treatment option and thus requires an accurate dosimetry standard. However, a dosimetry standard for the direct measurement of the absolute dose to water for this particular source type is currently not available. An improved standard for the absorbed dose to water based on Fricke dosimetry of HDR 192Ir brachytherapy sources is presented in this study. The main goal of this paper is to demonstrate the potential usefulness of the Fricke dosimetry technique for the standardization of the quantity absorbed dose to water for 192Ir sources. A molded, double-walled, spherical vessel for water containing the Fricke solution was constructed based on the Fricke system. The authors measured the absorbed dose to water and compared it with the doses calculated using the AAPM TG-43 report. The overall combined uncertainty associated with the measurements using Fricke dosimetry was 1.4% for k = 1, which is better than the uncertainties reported in previous studies. These results are promising; hence, the use of Fricke dosimetry to measure the absorbed dose to water as a standard for HDR 192Ir may be possible in the future.

A Spongosorites sp. collected during trawling operations off the southern coast of Australia returned the new alkaloid dragmacidin E (3), the structure of which was secured by detailed spectroscopic analysis. Dragmacidin E (3), and its co-metabolite dragmacidin D (1) have been identified as potent inhibitors of serine-threonine protein phosphatases.

Fire ephemerals are short-lived plants that primarily germinate after fire. Fresh and laboratory-stored seeds are difficult to germinate ex situ, even in response to fire-related cues such as heat and smoke. Seeds of eight Australian fire ephemeral species were buried in unburnt and recently burnt sites of natural bushland during autumn. Seeds were exhumed after 6 and 12 months and incubated in water and smoke water, either with or without a heat treatment at 70 degrees C for 1 h. Generally, germination did not increase after 6 months of burial, but after 12 months of burial germination was enhanced in seven of the eight species. Actinotus leucocephalus produced higher germination following 12 months of burial without any further treatment, and smoke water and heat further improved germination. The four Gyrostemonaceae species, Codonocarpus cotinifolius, Gyrostemon racemiger, Gyrostemon ramulosus and Tersonia cyathiflora, only germinated in the presence of smoke water, and their germination was enhanced by burial. Burial improved germination in response to a heat treatment in Grevillea scapigera and Alyogyne huegelii seeds, but did not enhance Alyogyne hakeifolia germination. During concurrent dry laboratory storage of seeds at 15 degrees C, only Actinotus leucocephalus produced increased germination in response to smoke water and heat over time. In summary, soil burial can alter the dormancy status of a number of Australian fire ephemeral seeds, rendering them more responsive to germination cues such as smoke water and heat. The requirement for a period of burial before seeds become responsive to smoke and/or heat would ensure that seeds persist in the soil until a subsequent fire, when there is an increase in nutrients available for growth and reduced competition from other plants.
