background because of difficulty in obtaining a 24-hour urine collection in children, a random sample of urine is often used to calculate the urinary calcium to creatinine ratio. urinary calcium excretion might be influenced by genetic, geographic area, etc. in this study, the value of urinary calcium, creatinine, sodium and potassium excretion and age–related reference values for urine calcium...
in this study, the role of soil properties in making difference between plant communitieswas examined. first, four plant types were identified, including pteropyrumaucheri-salsolarigida، astragalus gossypinus - acanthophyllum herateens، amygdalus scoparia – achilla millefolium and ephedra intermedia – erigon capestra, through randomized systematic sampling and field survey in representative are...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
In the present study, fast disintegrating tablets were designed with a view to enhance patient compliance. In this method, the hull of Hordeum vulgare, cross carmellose sodium, and sodium starch glycolate were used as superdisintegrants (4 and 6%), along with microcrystalline cellulose and mannitol, to enhance mouth feel. The prepared batches of tablets were evaluated for hardness, friability, ...
Introduction: Marl is one of the most important sedimentary units are in Iran because of the physicochemical characteristics and high rate of erodibility. These properties caused large civil damages and environmental impacts and so, the study of erosion and erodibility of the marl units is necessary. One of the most important points about marls is elements in them and grain size nature and ...
Objective: Soil salinity is one of the major worldwide environmental constraints affecting agricultural production in arid and semiarid regions. Lack of proper management of water and soil resources lead to increase soil salinity and reduce soil fertility. On the other hand, it seems simple and cheap method of measuring soil salinity is necessary. The aim of this study was to determine the rela...
In this study, at first the magnetite (Fe3O4) nano particles were prepared by sol-gel method under inert atmosphere using ferric nitrate (Fe (NO3)3.9H2O) and ethylene glycol (C2H6O2) as precursors. In the next stage, magnetite nanoparticles were modified by Sodium citrate under Ar atmosphere. Also zinc oxaid (ZnO) nanoparticles were provided via co-precipitation route and heat treatment using a...
