background identification of a normal range for biomarkers, based on pregnancy outcomes (caused by their high or low values) is of special importance in clinical studies. as some pregnancy outcomes can happen in both high and low levels of biomarkers, the receiver-operating characteristic (roc) curve is unsuitable for identifying these levels separately; rather, a statistical method is preferab...

Defining the Cyprus Green Line is a contested issue. Since accession to European Union of Republic (RoC) in 2004, EU has had balance between two conflicting definitions Line. The first, set by international law and United Nations (UN) resolutions, that peace line only temporary internal discontinuity within RoC, separating both communities until settlement agreed. second, championed Turkey Turk...

1. introduction extensive fires in the forests are examples of natural crises (hosseinali, 2005) and forest fire events are increasing in the conditions of changing climate and global warming; (azizi and yousefi, 2005). this phenomenon is considered one of the most destructive factors for forest ecosystems, causing irreparable damages (marozas et al, 2007). some of these damages include land us...

Purpose. To build new models with the Ocular Response Analyzer (ORA) waveform parameters to create new indices analogous to established topographic keratoconus indices. Method. Biomechanical, tomographic, and topographic measurements of 505 eyes from the Homburger Keratoconus Centre were included. Thirty-seven waveform parameters (WF) were derived from the biomechanical measurement with the ORA...

BACKGROUND Anaerobic threshold (AT) is recognized as objective and direct measurement that reflects variations in metabolism of skeletal muscles during exercise. Its prognostic value in heart diseases of non-chagasic etiology is well established. However, the assessment of risk of death in Chagas heart disease is relatively well established by Rassi score. But, the added value that AT can bring...

fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...

سابقه و هدف: به‌ منظور بررسی الگوی مکانی تغییر پوشش جنگلی برای شهرستان ملکشاهی در استان ایلام طی دوره 1355 تا 1393 از روش مدل‌سازی رگرسیون لجستیک استفاده شد. مدل رگرسیون لجستیک قادر است ارتباط بین تغییر پوشش جنگلی (متغیر وابسته) و عوامل مؤثر بر آن (متغیرهای مستقل) را به‌ خوبی تبیین کند. مواد و روش‌ها: برای بررسی تغییرات پوشش جنگلی، تصاویر ماهواره لندست 1 سنجنده MSS مربوط به سال 1355 و تصاویر ما...

The adsorption of Fe2+ by the manganese oxide coated zeolite (MOCZ) and iron oxide coated zeolite (FOCZ) was studied. Surface properties of adsorbents have been investigated for monitoring their changes and morphology for both of the MOCZ and FOCZ. Main variables namely; contact time, pH, initial concentration of Fe2+, size and dosage of adsorbent have been optimized, and the results contrasted...

Some biological aspects of semen were investigated in the Persian sturgeon, Acipenser persicus, by determination of seminal plasma indices (ionic composition and osmolality), sperm density and their relationships with sperm motility. The osmolality of seminal plasma ranged from 42.00 to 111.00 mOsmol Kg-1. The concentrations of Sodium (Na+), Potassium (K+), Chloride (Cl-), Calcium (Ca2+) and Ma...

Introduction: Azo groups of dyes used widely for coloring yarn. Methylene blue is one of this group's dyes therefore with benzene rings in its structure caused the toxicity and its persistence in the environment. So that the its deficiency of proper treatment can cause the irreparable damage to the environment. One of the ways to removal these dyes from natural sources are absorbed by the absor...
