in this paper, after collecting the rock samples from eight mines and one high way slope, the tests for determination of dry density, uniaxial compressive strength, tensile strength (brazilian test), elastic modulus, schmidt hammer rebound number have been done on samples. in addition, in order to calculating the mean size of rock grains, quartz content, hardness and abrasivity, a thin sections...

purpose the purpose of this study was to describe the body structure and morphological characteristics of tunisian elite handball players, and to determine the effect of these variables on functional and physical performance levels. methods a sample of 42 male handball players (mean age 21.98±3.24 years; training duration 12 years) at international level was submitted to a test battery comprisi...

land evaluation is the process of predicting the land use potential on the basis of its attributes. at the present study the qualitative land suitability evaluation was investigated for specific cereal crops including irrigated wheat (triticum aestivum l.), mays (zea mays l.) and cotton (gossypium herbaceum l.), based on fao land evaluation frame works (1976, 1983 and1985), climatic and soil re...

freeze-thaw is one of the most powerful weathering agents that may cause a rapid change in the initial engineering properties of stones, and limit their durability. freeze-thaw induces stress over the pores’ surface of stones. consequently, stone durability is closely related to its engineering and physical properties. the purpose of this study is estimating the engineering properties of deteri...

physical properties of fruits and vegetables are the subject of many researches because of its importance in designing of agricultural machinery. banana fruit is one of important fruit. in this study some physical properties of banana fruit (cavendish variety) were determined. properties which were measured included weight of whole fruit peel and pulp weight, dimensions, surface area and projec...

the superficial strata of ground have been perennially exposed to the action of natural agents such as heat, cold and water. however, grazing agent was not different from them when soils were investigated from temperate rangelands of kashmir and caused the soil compaction, soil structure degradation and loss of soil organic c and c/n ratio. soils from three grazing intensities were investigated...

in order to provide the data needed for the design of saffron processing equipment, physical properties of its flower were investigated. these properties included dimensions, mass, true and bulk densities, porosity, static and dynamic coefficients of friction, and terminal velocity as a function of moisture content. the average range of these properties for the three different parts of saff...

Aluminum alloys such as Al 5083 have primary potential for lightweight structural application in automotive and aerospace industries. This paper addresses the mechanical and tribological properties and corrosion resistance of chromium nitride coatings deposited on Al 5083 that can be used for development of applications of aluminum 5083 alloy. The CrN coatings of 1 μm thickness were deposited b...
