Three distinct groups of eclogites (low-Mg–Ti eclogites, high-Ti eclogites and Mg-rich eclogites) and ultramafic rocks from the depth interval of 100–680 m of the Chinese Continental Scientific Drill Hole were studied. The lowMg#s (=100⁎molar Mg/(Mg+Fe)) (81–84%) and low Ni (1150–1220 ppm) and high Fe2O3 total (13–15 wt.%) contents of ultramafic rocks suggest a cumulate origin. Mgrich eclogites...
The authors describe a new type of titanium (Ti) implant as a Modi-anodized (ANO) Ti implant, the surface of which was treated by sandblasting, acid etching (SLA), and anodized techniques. The aim of the present study was to evaluate the adhesion of MG-63 cells to Modi-ANO surface treated Ti in vitro and to investigate its osseointegration characteristics in vivo. Four different types of Ti imp...
Bioavailability of engineered metal nanoparticles affects uptake in plants, impacts on ecosystems, and phytoremediation. We studied uptake and translocation of Ti in plants when the main source of this metal was TiO2 nanoparticles. Two crops (Phaseolus vulgaris (bean) and Triticum aestivum (wheat)), a wetland species (Rumex crispus, curly dock), and the floating aquatic plant (Elodea canadensis...
Arsenic contamination in drinking water has become an increasingly important issue due to its high toxicity to humans. The present study focuses on the development of the yttrium-based adsorbents, with basic yttrium carbonate (BYC), Ti-loaded basic yttrium carbonate (Ti-loaded BYC) and yttrium hydroxide prepared using a co-precipitation method. The Langmuir isotherm results confirmed the maximu...
Thalassemia Intermedia; Folic Acid and Vitamin B12 Supplementation. What We Know and What is Needed?
This study presented a mini review on folic acid deficiency and recommendations for its supplementation in thalassemia intermedia (TI). TI is a clinical condition which lies between thalassemia major and thalassemia minor. Although TI patients may not need regular blood transfusion, precise diagnosis and management are critical for the prevention of clinical complications and quality of life im...
در این پژوهش کاتالیستهای زیگلر-ناتای واحد hdpe پتروشیمی اراک مورد بررسی قرار گرفته است . واحد مزبور از دو کاتالیست تجاری بنام های the و thb برای تولید گریدهای مختلف پلی اتیلن سنگین با توزیع وزن مولکولی باریک و پهن استفاده می کند که از واکنش ticl4 با پایه mg (oet)2 حاصل می شوند. در این تحقیق مشخص شد که در مقایسه با کاتالیستهای نگهداشته شده با mgcl2، میزان تیتانیم کاتالیستها بالا است (the، 9 درصد...
X-ray spectra of high energy density ~HED! Z-pinch plasmas have been analyzed by means of a comprehensive kinetic modeling. A new diagnostic, x-ray spectropolarimetry, was applied to study anisotropy of Z-pinch plasma. This diagnostic is based on theoretical modeling of polarization-dependent spectra measured simultaneously by spectrometers with different sensitivity to polarization. Specifical...
background: as condition and component of culture determine fate map of spermatogonial stem cells (sscs), the aim of this study was to evaluate of growth factors gdnf, lif and ra on proliferation and differentiation of ssc. materials and methods: sscs were cultured in two groups: the first group gdnf and lif and the second group ra. the number of clumps and colony formation was monitored during...
The lava section in the Troodos ophiolite, Cyprus, is chemically stratified and divided into a shallow lava sequence with low TiO2 content and a deeper lava sequence with high TiO2 content. We calculate the viscosity at magmatic temperature based on major element chemistry of lavas in Cyprus Crustal Drilling Project (CCSP) Holes CY-1 and 1A. We find that typical shallow low-Ti lavas have a magm...
