BackgroundLao People’s Democratic Republic has frequent outbreaks of vaccine-preventable diseases (VPD). This study aimed to determine susceptibility and exposure VPD in Saravan, a rural province with high ethnic diversity some the poorest health indicators nationwide.MethodsPatients from three district hospitals one provincial hospital were enrolled. Serum was tested by ELISA for IgG against h...

The present study sustainable management of Guilan Saravan Sylvan Park was planned. The used method in the form of decision support model in three10-year period was studied for parks of various states and with considering the economic, ecological and social criteria during the years 2008 to 2038. By using hierarchical fuzzy analysis method, the reaching to an optimal level of economic, ecologic...

extension of inter-turn fault in windings of pmsm can damage all parts of electrical systems, and in some cases in sensitive applications may lead to irreparable events. identification of such small faults at incipient steps can be so helpful to protect entire part of electrical system. in this paper, intelligent protection system is designed which is made by two major parts. in the first part ...

the sangbast-shandiz fault zone, with a length of about 57 km, a width of moderately 2 km, and a nw-se direction, is located about 15 km in the west of mashhad city. that is one of the major faults in the binalud mountains. geomorphic evidences illustrate that the sangbast-shandiz fault zone has dextral strike- slip offsets with thrust activity. in this article, we investigated geomorphic featu...

landfill gas is generated by organic waste decomposing under anaerobic conditions. landfill gas contributes to the emission in the atmosphere of greenhouse gases and causing global warming. humidity of environment is an effective parameter on rate of gas generation in landfills. saravan landfill is investigated as study area in this research. it located in 20 kilometers of rasht-tehran highway....

an attempt has been made to explore the general trends in the seismic response of planasymmetric structures when subjected to near-fault and far-fault ground motions. systems with structural wall elements in both orthogonal directions considering actual and common nonlinear behavior under bi-directional excitation were studied. idealized single-storey models with uni-axial eccentricity were emp...

fault zones and fault-related fracture systems control the mechanical behaviors and fluid-flow properties of the earth’s crust. furthermore, nowadays, modeling is being increasingly used in order to understand the behavior of rock masses, and to determine their characteristics. in this work, fault zones and fracture patterns are reviewed, and also comprehensive studies are carried out on the fr...
