Estudo das Interacções entre Mamíferos Marinhos e a Pesca de Cerco na Costa Oeste Portuguesa.
No presente relatório apresentam-se os resultados de um estudo que pretendeu avaliar a importância das interacções dos mamíferos marinhos com a pesca de cerco, identificando as espécies envolvidas, a taxa de encontros e as consequências para a pesca e para os mamíferos marinhos. O estudo envolveu a realização de observações a bordo de cercadoras dos portos da Figueira da Foz, Sesimbra, Setúbal e Sines. Foram também analisados dados de observação de cetáceos recolhidos em campanhas de investigação dos navios\ud
“Noruega” e “Capricórnio”, em 1997 e 1999, de modo a obter informação sobre a distribuição e abundância relativa dos cetáceos na costa portuguesa. O golfinho-comum foi a espécie mais abundante. Os cetáceos estiveram presentes ou interferiram, respectivamente em 13 % e 8 % dos eventos de pesca. As interacções observadas foram do tipo operacional, mas não afectaram os valores do esforço de pesca ou da captura por unidade de esforço (CPUE)
Income inequality and technological adoption
We relate technological adoption (of different technologies) with income inequality. In the process, we discover that some technologies, such as aviation, cell phones, electric production, internet, telephone, and TV, are skill-complementary in raising inequality. We construct standardized indexes of skill-complementary technological adoption for modern information and communication technologies (ICT), older ICT, production and transport technologies. We find strong evidence that older ICT and transport technologies (and less frequently modern ICT) tend to increase inequality. Additionally, we discover that results are much stronger in rich countries than in poor ones. Our results are quite robust to a series of changes in specifications, estimators, samples, and measurement of technology adoption. These results may bring insights into the design of incentive schemes for technology adoption.info:eu-repo/semantics/acceptedVersio
Human capital and genetic diversity
This paper investigates the relationship between human capital and the ancestral genetic diversity of populations. A simple model highlights a new channel through which genetic diversity can affect development: human capital. Additionally, empirical evidence of an unconditional hump-shaped relationship between genetic diversity and human capital is documented. This relationship decreases statistical significance when other deeply rooted determinants of human capital are taken into account. However, we found some significantly positive (linear) effects of genetic diversity. Thus, if there is a relationship between genetic diversity and human capital, this relationship tends to be positive: more genetic diversity is beneficial to human capital.info:eu-repo/semantics/acceptedVersio
Evidence-based integrated environmental solutions for secondary lead smelters: Pollution prevention and waste minimization technologies and practices
An evidence-based methodology was adopted in this research to establish strategies to increase lead recovery and recycling via a systematic review and critical appraisal of the published literature. In particular, the research examines pollution prevention and waste minimization practices and technologies that meet the following criteria: (a) reduce/recover/recycle the largest quantities of lead currently being disposed of as waste, (b) technically and economically viable, that is, ready to be diffused and easily transferable, and (c) strong industry interest (i.e., industry would consider implementing projects with higher payback periods). The following specific aims are designed to achieve the study objectives: Aim 1 – To describe the recycling process of recovering refined lead from scrap; Aim 2 – To document pollution prevention and waste management technologies and practices adopted by US stakeholders along the trajectory of LAB and lead product life cycle; Aim 3 – To explore improved practices and technologies which are employed by other organizations with an emphasis on the aforementioned criteria; Aim 4 – To demonstrate the economic and environmental costs and benefits of applying improved technologies and practices to existing US smelting operations; and Aim 5 – To evaluate improved environmental technologies and practices using an algorithm that integrates quantitative and qualitative criteria.
The process of identifying relevant articles and reports was documented. The description of evidence was presented for current practices and technologies used by US smelters as well as improved practices and technologies. Options for integrated environmental solutions for secondary smelters were introduced and rank ordered on the basis of costs (i.e., capital investment) and benefits (i.e., production increases, energy and flux savings, and reduction of SO2 and slag). An example was provided to demonstrate the utility of the algorithm by detailing the costs and benefits associated with different combinations of practices and technologies. The evidence-based methodology documented in this research reveals that it is technically and economically feasible to implement integrated environmental solutions to increase lead recovery and recycling among US smelters. The working example presented in this research can be confirmed with US stakeholders and form the basis for implementable solutions in the lead smelter and product industries to help reverse the overall trend of declining life-cycle recycling rates
Income inequality, TFP, and human capital
WOS:000399319600005 (Nº de Acesso Web of Science)A fruitful recent theoretical literature has related human capital and technological development to income (and wage) inequality. However, empirical assessments on the relationship are relatively scarce. We relate human capital, total factor productivity (TFP) and openness to inequality and discover that, when countries are assumed to be heterogeneous and dependent cross-sections, human capital is the most robust determinant of inequality, contributing to increasing inequality, as predicted by theory. TFP and openness turned out to be non-significantly related to inequality. These results are robust to a number of robustness tests on specifications and data and open up the prospect of theoretical research on the country-specific features conditioning the effect of human capital, technology and trade on inequality.info:eu-repo/semantics/acceptedVersio

Differences in salivary α-amylase levels among women with different taste sensitivities
Saliva is the main component of taste receptor cells external environment, and consequently it may have a decisive role in taste perception. Taste sensitivity varies among different individuals. Sensitivity to the compound n-6-propylthiouracil (PROP) has been considerably studied and besides the known influence of genetic background, the contribution of perireceptor environment is not completely clear yet. Salivary α-amylase (one of the main proteins of saliva) is involved in carbohydrate digestion and its enzymatic activity may change the levels of sugars present in the mouth, influencing food perception. To evaluate differences in salivary total protein content and α-amylase activity and expression among individuals with different PROP taste sensitivities. Sixty seven female women (18-30 years old) were classified in one of the three groups of taste sensitivity (non-taster, medium-taster or super-taster), according to the perceived intensity for PROP, using Labeled Magnitude Scales. Saliva was collected without stimulation. Flow rate was calculated by dividing total volume for the 5 minutes collection. Bradford method was used for total protein assessment. Dinitrosalicylic acid assay was used for measuring the starch-hydrolyzing activity of salivary α-amylase, while the expression of this enzyme was evaluated by Wester blot. 20,9% of the subjects were classified as non-taters. The three groups presented similar saliva flow rates and total protein content was not significantly different although a tendency for lower protein concentration in medium-tasters individuals was observed. Salivary α-amylase activity (U/min) was higher in supertasters (P<0,05). Salivary α-amylase activity (U/min) was higher in super-tasters (P<0,05) without any significant differences in expression. In women individual differences in saliva composition can contribute to the different taste sensitivity. One of the differences appears to be α-amylase enzymatic activity. The reason for this deserves to be elucidated, as well as the potential involvement of others salivary proteins
Prediction of the mechanical behavior of the Oporto granite using data mining techniques
The determination of mechanical properties of granitic rocks has a great importance to solve many engineering problems. Tunnelling, mining and excavations are some examples of these problems. The purpose of this paper is to apply Data Mining (DM) techniques such as multiple regressions (MR), artificial neural networks (ANN) and support vector machines (SVM), to predict the uniaxial compressive strength and the deformation modulus of the Oporto granite. This rock is a light grey, two-mica, medium-grained, hypidiomorphic granite and is located in Oporto (Portugal) and surrounding areas. Begonha (1997) and Begonha et al. (2002) studied this granite in terms of chemical, mineralogical, physical and mechanical properties. Among other things, like the weathering features, those authors applied correlation analysis to investigate the relationships between two properties either physical or mechanical or physical and mechanical. This study took the data published by those authors to build a database containing 55 rock sample records. Each record contains the free porosity (N48), the dry bulk density (d), the ultrasonic velocity (v), the uniaxial compressive strength (σc) and the modulus of elasticity (E). It was concluded that all the models obtained from DM techniques have good performances. Nevertheless, the best forecasting capacity was obtained with the SVM model with N48 and v as input parameters.Fundação para a Ciência e a Tecnologia (FCT
