AIM To determine the type of anemia, iron deposit and risk factors for anemia in the elderly. METHODS A cross-sectional study was conducted among 84 patients admitted to the geriatric inpatient ward of dr. Cipto Mangunkusumo Hospital. The patients underwent anamnesis, administration of a dietary questionnaire which included SQFF and food recording, physical examination, laboratory investigati...
BACKGROUND Iron-overload cardiomyopathy is a major cause of death in thalassemia patients due to the lack of an early detection strategy. Although cardiac magnetic resonance (CMR) T2* is used for early detection of cardiac iron accumulation, its availability is limited. Heart rate variability (HRV) has been used to evaluate cardiac autonomic function and found to be depressed in thalassemia. Ho...
Alumina-rich iron ore is a widely existed polymetallic deposit in the nature, and it has a high comprehensive utilization value. Because the alumina and iron contents of alumina-rich iron ore vary from each other, there are many different measures and processes to recover iron and alumina from the various kinds of alumina-rich iron ore. In the blast furnace (BF) ironmaking process, the alumina ...
Introduction: Observations made by the Opportunity rover during its traverse south from Eagle crater show that the hematite bearing plains are an aeolian lag deposit consisting of hematite spherules and basal-tic sand, along with a nanophase iron oxide bearing dust component, that has been worked into ripples [1,2,3]. The hematite spherules, which have weathered out of the sulfate rich outcrop ...
GIS is considered an important technique as well as a prerequisite for cost effective mineral exploration and determination of high potential areas. The purpose of this research is to determine high potential iron zones for detailed exploration using index overlay GIS method. Index Overlay was used to combine the geology, topography (scale: 1:1,000), lineaments, remote sensing (ASTER and ETM+) ...
The Jagpura Au-Cu deposit is situated within the Aravalli craton in northwestern part of India. In present work, petrography, mineral chemistry, fluid inclusion and sulfur isotopic compositions were used to study deposit. ore association arsenopyrite, loellingite, chalcopyrite, pyrrhotite pyrite, along with native gold, magnetite apatite. gold fineness ranges from 914–937‰ (avg. 927‰). presence...
BACKGROUND Iron overload cardiomyopathy remains the major cause of death in patients with transfusion-dependent thalassemia. Cardiac T2* magnetic resonance imaging is costly yet effective in detecting cardiac iron accumulation in the heart. Heart rate variability (HRV) has been used to evaluate cardiac autonomic function and is depressed in cases of thalassemia. We evaluated whether HRV could b...
محدوده اکتشافی حاج الیاس در فاصله 190 کیلومتری جنوب بیرجند و 160 کیلومتری جنوب شرقی شهرستان خوسف واقع است. وجود کارهای معدنی قدیمی (شدادی) و بررسی نقشه های ژئوفیزیکی هوایی این محدوده را به عنوان یک پتانسیل آهن معرفی کرده است. جهت شناسایی نقاط امید بخش آهن دار و معرفی موقعیت آنها جهت مطالعات بعدی، در این پروژه از روش ژئوفیزیکی ژئومغناطیس استفاده شده است. روش ژئومغناطیسی اولین روش ژئوفیزیکی در اک...
