the purpose of this study is designing a model to determine important factors on export performance (ep) in the base of cost leadership strategy for non_ metal mineral industry of iran. in this paper, available approaches in the scope of determinants of ep are identified consist of contingency view, relational and resource based view. in this study, we examine relationship between resources, co...

The accumulation of mineral salts in plants has heretofore been demonstrated mainly by microchemical means, a method which is not always satisfactory for quantitative ends, since some of the minerals may be masked through organic combinations, and since the amount of color produced, in reactions dependent on colors, is not necessarily proportional to the amount of mineral present in the tissues...

background & aim: oleuropein has pharmacologic properties and is the main component of olive leaves which is considered to be the most pharmacologic compounds of olive (olea europaea l.). the aim of this work was to investigate the possible using of the extract of this plant in food industry (sponge cake) in order to take advantage of its medicinal properties.experimental: ethanolic extract...

In this study, the effect of cladded tungsten carbide layer upon HSS - M2 tool steel on microstructure, hardness, and wear behavior has been studied in two cases without using the middle layer and using the middle layer of nickel. Tungsten Carbide cladded on HSS - M2 tool steel by Arc Weld ( SMAW ). The ASTM-G65 wear test was used to determine its application for use in the mineral indus...

purpose: given that weight and body mass index (bmi) are considered as modifiable factors in osteoporosis, the present study aimed to examine the relationship of weight and bmi with bone mineral density (bmd) and bone mineral content (bmc) at the femur and lumbar vertebrae in perimenopausal women. methods: in this descriptive-correlational study, we measured the bone density of the femur and lu...

Introduction The mining industry is responsible for several detrimental effects on health and the environment through the mining process itself as well as through pollution. Although there is a wide range of health impacts associated with mining depending on the mineral and mining type, dust is common to all types of mine processes, and respiratory effects, especially for workers, are among the...

The epidemic of mesothelioma in Cappadocia, Turkey, is unprecedented in medical history. In three Cappadocian villages, Karain, Tuzkoy and "old" Sarihidir, about 50% of all deaths (including neonatal deaths and traffic fatalities) have been caused by mesothelioma. No other epidemic in medical history has caused such a high incidence of death. This is even more unusual when considering that (I) ...

This manuscript focuses on the production of polymeric matrices enriched in minerals and antioxidant compounds. The biopolymers employed are obtained from different by-products agro-food industry (porcine plasma protein, pea protein concentrate soy isolate), which helps to revalorize them. Two manufacturing techniques produce these matrices: 3D-printing injection molding. Bioactivity was enhanc...

Wood is a naturally renewable material with both continuous and isolated pore systems. Wood-composite panels have the privilege of offering a homogeneous structure to be used as constructional and structural materials. However, its nature makes it susceptible to biological wood-deteriorating agents, water absorption and thickness swelling, fire, etc. Using nano-materials are very easy in the wo...

Introduction: The relationship between elevated level of gas and particulate pollutants with increased mortality resulting from cardiovascular and respiratory diseases has been presented in epidemiological studies. Although the principal mechanisms of diseases are still unknown, inflammatory and homeostatic processes have been known to be related to this issue. Accordingly, this study was condu...
