The PII proteins are found in all three domains of life as key integrators of signals reflecting the balance of nitrogen and carbon. Genetic inactivation of PII proteins is typically associated with severe growth defects or death. However, the molecular…

Electrodeposition of Pt nanoparticles under
potentiostatic conditions was performed on several types of carbon electrode supports: commercial macroporous carbon (a three-dimensional electrode), glassy carbon and
graphite. Conducting polymers (poly-aniline and poly-oaminophenol) were also used. The platinum nanoparticles were obtained by…

In this paper, we analyze the relation between the surface curvature of an isolated charged conductor and resultant electrostatic potential. The study will be performed for a long conductor with uniform cross section. It will be demonstrated by geometric arguments…

Multi-agent systems (MAS) offer an approach to solve complex problems where data and control are inherently distributed among several agents. Normally, agents have to cope with conflicts based on inconsistent knowledge which arise when they exchange information. A relative common…

The electrochemical oxidation of the aniline dimers 2-aminodiphenylamine (2-adpa) and 4-aminodiphenylamine (4-adpa) has been
performed in strongly acidic medium on platinum, graphite, and indium tin oxide electrodes. The resulting films have been
characterized by a number of electrochemical, microscopic, and…

Can you imagine a useful task you would like a social robot to perform for you? This paper presents an Internet survey where participants were asked this question to identify applications for social robots. The applications mentioned by the participants…

Objective: To review studies of anxiety in critically ill patients admitted to an intensive care unit to describe the level of anxiety and synthesize the psychometric properties of the instruments used to measure anxiety. Methods: The CUIDEN, IME, ISOC, CINAHL,…

This study examines the relevance of environmental management as a source of competitive advantage for hotels. The relationship between the environmental proactivity of hotels located in the province of Alicante (Spain) and their economic performance levels was studied, and three…

We argue that ethical leadership must be in line with corporate governance in general and of the Chief Executive Officer (CEO) who must be the starting point for the rest of the organisational members to have an ethical guideline to…
