Türkiye, göç hareketlerinin yoğun olarak yaşandığı bir coğrafyada yer almaktadır. Bu bağlamda olgusunu siyasi, sosyal, kültürel ve ekonomik yönden öğrencilere aktarmak, sebep sonuçlarını ifade etmek açısından eğitimi büyük önem arz etmektedir. Göç gibi kritik konuların anlatımında geleneksel yaklaşımların kullanımı yerine okul çağında bulunan yaş gruplarının ilgisini çekebilecek materyal oldukç...

New geological, bulk chemical and mineralogical (QEMSCAN and FEG-EPMA) data are presented for albitite-type uranium deposits of the Mount Isa region of Queensland, Australia. Early albitisation of interbedded metabasalt and metasiltstone predated intense deformation along D2 high strain (mylonite) zones. The early sodic alteration paragenetic stage includes albite, riebeckite, aegirine, apatite...

Strontium-89 (Sr-89) alone or with concurrent chemotherapy has a role in the treatment of patients with prostate cancer (PCP). The schedules for repeated doses of Sr-89 or for concurrent chemotherapy is undetermined. The objective of this study was to measure the effective half-life (Te) of Sr-89 using a detector available in a nuclear research facility. Blood and urine samples obtained from PC...

In a previous paper (1) it was shown that discrimination against strontium as compared to calcium, in the formation of synthetic hydroxyapatite, Calo(POJ)6(OH)2, was greater in large, more slowly grown crystals than in small, more rapidly precipitated crystals. The exclusion of strontium as compared to calcium in the hydroxyapatite crystals increases as the preparation conditions approach equil...

The thermodynamics and kinetics of the solid-state alloying of Zr-B, underlying a variety of synthesis processes of the ultrahigh-temperature ceramic ZrB2, are widely unknown. We investigate the energetics, diffusion kinetics, and structural evolution of this system using first-principles computational methods. We identify the diffusion pathways in the interpenetrating network of interstitial s...

Concerns have been raised within the nuclear medicine field about the accuracy of measurements of 89Sr. The 85Sr impurity present in the 89Sr solution has a significant effect on the response of radionuclide calibrators used in hospitals. A comparison was conducted between the National Physical Laboratory (NPL) and the UK hospital physics community. Only 58% of the results were within 5% of the...

The purpose of this paper is to explain the thermodynamical and shape memory behaviour in comparison with structural parameters for Zr-based intermetallics a new class of potential shape memory alloys (SMA) for high-temperature applications [I]. Electrical resistivity, structural, shape memory and calorimetric measurements were carried out for the Zr2CuNi Zr,CuCo quasibinary cross-section. It w...

Recent results of CRIEPI’s pyro-process fuel cycle technology developments are reported. On the actinides deposition into liquid cadmium cathode, a series of experiments are conducted using a small scale electro-refiner of about a hundred grams actinides inventory. The suitable condition for codeposition of U and TRUs is investigated, by varying Pu/U ratio in the salt from ∞ to 1.7. The design ...
