this paper examines some of the results of the archaeological survey conducted in ardabil province in summer 2001. ardabil province is situated in northwest iran and in the neighborhood of of azerbaijan republic. the survey of the surrounding area gives an account of the different graves. the greaves are characterized by simple grave; megalithic graves with and without stele and kurgan mound. t...

salinity of soil and water is the most important agricultural hazard in arid and semi-aridregions. in saline soils, yield production directly influences by soluble salts in the root zone aswell as by shallow water table depth. the first step for reclamation of such soils is reducingsalinity to optimum level by leaching. the objective of this study was to develop a practicalmodel to estimate wat...

Analysis of a laminated composite beam under impact by a rigid particle is investigated. The importance of this project is to simulate the impact of objects on small scale aerial structures. The stresses are considered uni- axial bending with no torsion loading. The first order shear deformation theory is used to simulate the beam. After obtaining kinematic and potential energy for a laminated ...

in the course of this study, empirical models were developed for the pressure-density relationship in a large cubic baler for baling alfalfa and barley straw. least squares regression analysis was employed to develop the empirical model and estimate the model coefficients by minimizing the summation of the squared differences between data resulting from the developed empirical model and the cor...

primary hepatic lymphoma is a rare malignancy usually presenting with symptoms of fever, hepatomegaly, jaundice and weight loss. this picture mimics infectious and inflammatory disorders and thus delays the diagnosis. here, we present a 47-year old man with prolonged fever who underwent several investigations and, in the meantime, developed fulminant hepatic failure before the diagnosis could b...

contact mechanics is related to the deformation study of solids that meet each other at one or more points. the physical and mathematical formulation of the problem is established upon the mechanics of materials and continuum mechanics and focuses on computations involving bodies with different characteristics in static or dynamic contact. contact mechanics gives essential information for the s...

pierre-gerlier forest and his colleagues make a strong argument for the need to expand policy capacity among healthcare actors. in this commentary, i develop an additional argument in support of forest et al view. forest et al rightly point to the need to have embedded policy experts to successfully translate healthcare reform policy into healthcare change. translation of externally generated i...

risk response planning is one of the main phases in the project risk management and has major impacts on the success of a large-scale project. since projects are unique, and risks are dynamic through the life of the projects, it is necessary to formulate responses of the important risks. the conventional approaches tend to be less effective in dealing with the impreciseness of risk response pl...
