Food borne diseases are considered as the major problems for public health in the world and salmonella serotypes are the most important pathogens causing these types of diseases. Present study was carried out for the isolation of salmonella and determination of their antibiotic sensitivity and serovars from local, industrial and breeder poultry eggs. In this cross-sectional survey, 300 samples ...

in this research, 514 soil samples and dead larvae were collected from khorassan, lorestan, tehran, ghazvin, east azarbaijan, west azarbaijan, mazandaran and hamedan provinces. b. thuringiensis was isolated from the samples using a heat-acetate method and the isolates were identified and classified using biochemical tests. the frequency of b. thuringiensis in soils with different plant communit...

The need for a reduction of the spacing between devices in integrated circuits has led to the development of several device isolation process schemes. In this chapter, we give an overview of the most important trends in isolation technologies, starting with the conventional LOCOS structure. A novel isolation structure that combines several of the features used in advanced isolation structures i...

background and objectives: bacillus species are attractive industrial organisms due to their rapid growth rates leading to a short fermentation cycle and for their capacity to secrete important enzymes and proteins such as xylanase into the extracellular medium. considering the industrial importance of xylanase, in this current study, bacillus spp. were isolated from different soils and were sc...

Introduction:The post-surgical management of patients with differentiated thyroid cancer include ablation of remnant local and distant metastatic tissues with 131I therapy, which accentuates isolation of the patient in order to avoid unnecessary radiation exposure to the care givers, general public and the environment. The duration of isolation is subject to the redu...

Supporting the isolation and atomicity of global transactions in multidatabase systems has become an increasingly difficult task. Local autonomy requires that the maintenance of isolation and atomicity as an execution condition of global transactions must also hold when such execution is interleaved with local transactions. This paper proposes the utilization of both the syntactic and semantic ...

The evolution of distributed applications to reflect structural changes or to adapt to specific conditions of the run-time environment is a difficult issue especially if continuous service is required from end-users. This latter constraint implies to perform changes with minimal penalty on the service provisioning. The set of tools and services that allow such a goal to be achieved is usually d...

This paper presents a continuous-time distributed fault detection and isolation methodology for nonlinear uncertain possibly large-scale dynamical systems. The monitored system is modeled as the interconnection of several subsystems and a divide et impera approach using an overlapping decomposition is adopted. Each subsystem is monitored by a Local Fault Diagnoser using the information based on...
