results local level of primary health care system in iran had mechanical structure, but in contextual dimensions the results showed different types. there was a significant relationship between structural and contextual dimensions (r = 0.642, p value < 0.001). goals and culture dimensions had strongest effects on structural dimensions. background in recent years, family physician plan was estab...

In this paper, analysis, simulation and design of a distributed amplifier (DA) with 0.13µm CMOS technology in the frequency range of 3-40 GHz is presented. Gain cell is a current reused circuit which is optimum in gain, noise figure, bandwidth and also power dissipation. To improve the noise performance in the frequency range of interest, a T-matching low pass filter LC network which is utilize...

although the high infection rate of microscopic sarcocyst occurs in cattle, to the best of our knowledge,there is no report about the identification of macroscopic sarcocyst in iran. in this work, sarcosystis hirsutawas first isolated from slaughtered cattle. in a 2-year-old slaughtered cattle, morphological examinationrevealed 3-5 mm in length cysts distributed in different striated muscles, p...

Greenstone is a software for creating and maintaining distributed digital library collections. It provides a sophisticated federation mechanism for the collections. In order to support alerting notification about changes in the distributed collections, we propose a distributed directory service for the management of the distributed Greenstone installations. The Greenstone directory service (GDS...

A practical distributed web crawler architecture is designed. The distributed cooperative grasping algorithm is put forward to solve the problem of distributed Web Crawler grasping. Log structure and Hash structure are combined and a large-scale web store structure is devised, which can meet not only the need of a large amount of random accesses, but also the need of newly added pages. Experime...
