Routine screening of harmful microorganisms in beach sands: implications to pub...

Beaches worldwide provide recreational opportunities to hundreds of millions of people and serve as important components of coastal economies. Beach water is often monitored for microbiological quality to detect the presence of indicators of human sewage contamination so as to prevent public health outbreaks associated with water contact. However, growing evidence suggests that beach sand can harbor microbes ha...

The amphipod Corophium multisetosum (Corophiidae) in Ria de Aveiro (NW Portugal...

The population of Corophium multisetosum Stock, 1952 in Areao displayed a semiannual, iteroparous life history. Mean longevity was similar to6 mo, with the estimated life span longer for overwintering individuals born in autumn than for individuals born in spring. Length-frequency data indicated that the length increment per moult is probably higher in males than females; however females moulted more frequently...

The amphipod Corophium multisetosum (Corophiidae) in Ria de Aveiro (NW Portugal...

The abundance and biomass of Corophium multisetosum Stock, 1952 were determined from benthic corer samples collected monthly over 1 yr in the upper reaches of Canal de Mira (Ria de Aveiro, Portugal). Both density and biomass over the sampling period were negatively correlated with water temperature and positively correlated with chlorophyll n concentration in the sediment. C, multisetosum density was significan...

O recém nascido de extremo baixo peso. Estado aos 2-3 anos. Resultados do Regis...

Background: Children born before 32 weeks or very low birth weight have a high risk for neurodevelopmental impairment. Aim: To analyze the condition of extreme low birth infants (weighing 1000g or less), born in the years 2005 and 2006, and included in the Portuguese National Very Low Birth Weight Network. Results: A total of 163 children were evaluated, 49.1% of which were males with a mean gestational age 27 ...

A contribution to a virtual enterprise taxonomy

This paper presents a taxonomy able to contribute to building a framework within the domain of Virtual Enterprises (VE). A VE taxonomy currently does not exist, and this lack is felt in the ambiguous way that some concepts are addressed, leading to a fragment understanding that hinders the development of the science of VE integration and management. The structure of the taxonomy developed is based on the view o...

O recém nascido de extremo baixo peso: estado aos 2-3 anos: resultados do Regis...

Introdução: As crianças que nascem antes das 32 semanas ou com peso inferior a 1500g apresentam um elevado risco de sequelas no seu neurodesenvolvimento. Objectivo: Analisar a situação do crescimento e desenvolvimento neurosensorial das crianças com peso igual ou inferior a 1000g nascidas nos anos de 2005 e 2006 incluídas no registo nacional do muito baixo peso. Resultados: Das 163 crianças avaliadas, 49,1% e...

Chemopreventive Efficacy of Atorvastatin against Nitrosamine-Induced Rat Bladde...

To investigate the anti-carcinogenic effects of Atorvastatin (Atorva) on a rat bladder carcinogenesis model with N-butyl-N-(4-hydroxibutil)nitrosamine (BBN), four male Wistar rat groups were studied: (1) Control: vehicle; (2) Atorva: 3 mg/kg bw/day; (3) Carcinogen: BBN (0.05%); (4) Preventive Atorva: 3 mg/kg bw/day Atorva + BBN. A two phase protocol was used, in which the drug and the carcinogen were given betw...

Biological assemblages of three new mud volcanoes along deep-reaching transform...

Previous work on the Gulf of Cadiz (S Iberian Margin) has revealed several mud volcanoes sitting on the accretionary wedge and aligned along west-east trending transform faults. The source of fluids in these mud volcanoes is several kilometres below the seafloor and their geochemical composition indicates that they are affected, in different degrees, by oceanic crust alteration, implying that there is active fl...

Offshore outsourcing in large companies: motivations and risks perceived

When companies opt for information systems (IS) outsourcing, within the set of contracted services, they can contract their entire service needs to onshore suppliers or to offshore companies, or part of these services can be contracted to onshore suppliers and the other part to offshore suppliers. The offshore outsourcing reveals itself nowadays as an important strategic option to IS management optimization. Th...
