The ability of the chicken to encode different aspects of spatial layout were investigated. In a first series of experiments, chickens were disoriented in a rectangular environment, where they proved able to reorient themselves using both geometric and non-geometric properties of the environment. In a second series of experiments, chickens were trained to find the central position of an arena u...

Highly active antiretroviral therapy (HAART) has become the standard for treating HIV infection. HIV protease inhibitors (PIs) have been used as amajor component of theHAART regimens over the past 10 years, along with nucleoside and non-nucleoside reverse transcriptase inhibitors. The introduction of these regimens resulted in an appreciable decline in morbidity and mortality due to HIV infecti...

In this paper it is presented an Agency for Integration, Archive and Diffusion of Medical Information (AIDA), which configures a data warehouse, developed using Multi-Agent technology. AIDA is like a symbiont, with a close association with core applications present at any health care facility, such as the Picture Archive Communication System, the Radiological Information System or the Electroni...

Arena is a software package intended to help e-commerce strategy researchers and designers test buying and selling strategies under different scenarios. It implements and adheres to a set of design criteria intended to ensure its simulation ability as well as prolonging its usable lifetime. The process of implementing Arena involved conducting background research into current strategies and the...

earlier studies reported the existence of E1 and E2 enzymes within mitochondria (Magnani et al, 1991; Schwartz et al, 1992). In addition, a more recent and growing body of evidence shows that mitochondria also contain specific E3 ligases with a prominent role in the regulation of mitochondrial dynamics. In particular, Mitol/ March5—a ubiquitin E3 ligase embedded in the outer membrane— participa...

Games have always been popular testbeds for Artificial Intelligence (AI). In the last decade, we have seen the rise of the Multiple Online Battle Arena (MOBA) games, which are the most played games nowadays. In spite of this, there are few works that explore MOBA as a testbed for AI Research. In this paper we present and discuss the main features and opportunities offered by MOBA games to Game ...

The institutions seek to improve their performance and quality of service, so that their patients are satisfied. This research project aims, conduct a time study program in the area of gynecological surgery, to determine the current level of capacity and optimize the programming time in order to adequately respond to demand. The system is analyzed by waiting lines and uses the simulation using ...

This paper presents a research conducted over the increasing dangers of cyberterrorism. It discusses the cyberterrorism parameters the cyberterrorists, the attacks, and the countermeasures – as well as the Internet’s physical security. The paper sounds an alarm over the current accessibility of critical intranets via the Internet, and points out that the risks in this practice outweigh any poss...

While preparing this paper, I pondered what a scientist’s perspective should be. Although I no longer work at the bench, I am closely involved in the continuum of scientific research through technology to its application, and especially in its transfer to developing countries. I will briefly consider six aspects of science and end with a challenge: to come up with new proposals for action. How ...

Civil engineering structures are part of our cultural heritage. The story of who we are can be told, in part, by what we have built. There have been pivotal moments in civil engineering design history wherein a master engineer creates a pioneering structure. One major example is Anton Tedesko’s 1936 Hershey Ice Arena, the first large-scale thin shell concrete roof in the United States. Tedesko ...
