In recent years, holographic optical elements have been introduced in different applications such as high-density data storage, interconnections, spatial and temporal filters and three-dimensional displays. Simultaneously, more sensitive, efficient and durable holographic materials have been developed. Thus it is necessary…

Prediction capacity of three main shoot population dynamics methods (age structure, net shoot recruitment per plagiotropic rhizome and shoot census) have been tested for a period of four years (2002–2006) on a Posidonia oceanica meadow. Accuracy of each method was…

In this paper we present a novel approach to assigning roles to robots in a team of physical heterogeneous robots. Its members compete for these roles and get rewards for them. The rewards are used to determine each agent’s preferences…

In this paper, I first refer to the center-periphery dichotomy in terms of scientific output, placing emphasis upon the relation that exists between science and technology development, on the one hand, and social and economic development, on the other. I…

A bactéria Pseudomonas putida tem se mostrado hábil na degradação de vários xenobióticos, porém são poucos os estudos a respeito da segurança de seu uso para a saúde humana. A fim de avaliar os possíveis efeitos toxicopatológicos da bactéria, uma…

The supervision of postgraduate Master's Degree dissertations has attracted little attention in the
academic literature and is an under researched area of supervisory activity. This research was a
response to generate new knowledge concerning the praxis of supervisors who supervise…

There is compelling evidence of a relationship between poly(ADP-ribosyl)ation and tumorigenesis; however, much less is known about the role of specific targets of poly(ADP-ribosyl)ation in tumor development. Two forms of the multifunctional transcription factor, CTCF, were previously identified: a 130-kDa…
