Se identifican en fracciones de membranas plasmáticas aisladas de células ascíticas AS-30D de hepatocarcinoma de rata, tres glicoproteínas de 125 kDa, 115 kDa y 105 kDa (gp125, gp115 y gp105) que son adenililadas utilizando ATP como sustrato. Esta adenililación es…

Este tutorial mostra com buscar tant el factor d'impacte d'una revista com les revistes amb major factor d'impacte d'una temàtica en el Journal Citation Reports (JCR).

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…

Nowadays, the material disassembly is an important issue for the industry. This paper presents an algorithm to sequence the task to be performed in the disassembly of a specific material from a product or to separate all the materials of…

This paper explores additivity-like properties ful…led by bankruptcy rules. Our
main result is that the unique rule satisfying an adittivity-like property is the Minimal Overlap proposed by O'Neill. We also propose some conections relative to
additivity properties in close frameworks…

This special issue of the Journal of Physical Agents is devoted to human interaction with domestic robots. The form, features and future, of domestic robotic devices, from entertainment-based agents through to robotic cleaners, companions, assistants and helpers, are considered and…

Based on the results of the coupled-wave theory the diffraction efficiency is calculated for thick phase transmission holographic gratings taking into account the chemical processing of the recording material. Three effects of processing are considered: variations in the average refractive…

Changes in the presynaptic inhibition of spinal alpha-motoneurons were studied in
athletes during motor activities of different types. In the state where muscles were at
relative rest, the presynaptic inhibition of spinal alpha-motoneurons of the m. soleus
was stronger in…

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…
