the aim of this research is to do an internal evaluation of the academic library based on the views of experts to identify the current situation. it also aims to present a method for library evaluation and to help the planners and managers of such centers to understand and improve the condition of university libraries and information centers. the methodology of this case study is based on inter...

The Artificial Neural Networks method is applied on visual working efficiency of cockpit. A Self-Organizing Map (SOM) network is demonstrated selecting material with near properties. Then a Back-Propagation (BP) network automatically learns the relationship between input and output. After a set of training, the BP network is able to estimate material characteristics using knowledge and criteria...

A 77-year-old-man who had been treated for chronic obstructive pulmonary disease (COPD) was referred to our hospital for further examination of a chest X-ray abnormality. The chest X-ray showed consolidation in the right upper and middle lung field. Chest computed tomography showed an airspace consolidation extending subpleurally and nonsegmentally without nodular lesions. The tentative diagnos...

During meiotic prophase in fission yeast, the nucleus undergoes dramatic oscillatory movements. A newly identified structure, the radial microtubule organizing center (rMTOC), mediates these movements and shares some of the features of the pericentriolar material in higher eukaryotes.

Pressure can transform a transparent material into an opaque one, quench the moments in a magnet and force solids to flow like liquids. At 15 GPa, the pressure found 500 km below the earth's surface, the semiconductors silicon and germanium superconduct. Yet, at this same pressure, we show here that the magnetism in metallic GdSi remains completely robust even as it shrinks by one-seventh of it...

Spindle formation is essential for stable inheritance of genetic material. Experiments in various systems indicate that Ran GTPase is crucial for meiotic and mitotic spindle assembly. Such an important role for Ran in chromatin-induced spindle assembly was initially demonstrated in Xenopus laevis egg extracts. However, the requirement of RanGTP in living meiotic cells has not been shown. In thi...
