The standard method to diagnose and follow-up osteoporosis is the measurement of bone mineral density (BMD) using dual X-ray absorptiometry (DEXA). Manufacturers' manuals of DEXA devices state the intrascanner coefficient of variance is less than 0.01 g/cm(2). The aim of this study was to evaluate the in vivo coefficient of variance of a Lunar DPX scanner in male and female healthy adult subjects. Average BMD for females and males were 1.170 +/- 0.091 g/cm(2) and 1.272 +/- 0.115 g/cm(2), respectively. Monthly phantom measurements provided and controlled by the manufacturer were 1.243 +/- 0.008 g/cm(2) (range 1.222 to 1.257) and the coefficient of variance was 0.006. It is concluded that the in vivo coefficient of variance of DEXA devices can slightly be higher than that proposed by the manufacturer.

Radiation induced chain addition of allylbenzene to 1,4-dioxane Nesterov, SV; Kucukyavuz, S; Önal, Ahmet Muhtar (Springer Science and Business Media LLC, 1999-06-01) Radiation induced chain addition of allylbenzene to 1,4-dioxane has been studied by IR-, UV-, mass-, NMR- and ESR-spectrometry. Efficiency of the addition depends on the concentration of monomer and it has an optimum at C-monom<0.125M. Apparently, upper concentration limit of the reaction is caused by absorbed energy transfer on the molecule of monomer followed by energy deactivation. Radiation-chemical yields of the product are 12 and 31 molec./100 eV for 0.125M and 0.07M solution, respectively. The value ...
Trace elements in human bone determined by neutron activation analysis Aras, NK; Ertaş, Gülay; Alkan, S; Korkusuz, F (Springer Science and Business Media LLC, 1999-01-01) There is an evidence that some of the essential trace elements are crucial determinants of bone health. Excess or deficiency of these elements has a role in the development of bone diseases, therefore research on trace elements in bone is very important. Iliac crest bone biopsies were optioned from twelve persons undergoing orthopedic surgery due to any reason than osteoporosis. Cortical and trabecular parts were separated, and blood and fats were removed. Up to 30 minor and trace elements were determined i...
FINE-STRUCTURE OF MASS AND CHARGE-DISTRIBUTION IN LOW-ENERGY FISSION ERTEN, HN; ARAS, NK (Springer Science and Business Media LLC, 1992-04-01) Studies of finer details in mass and charge distribution in fission leads to a better understanding of the fission process. Experimental determination of independent and cumulative yields using radiochemical techniques as well as mass spectrometers and fission product recoil separators form the basis of such studies. It has been established that closed shells as well as an even number of nucleons influence both mass and charge distributions. The magnitudes of these effects may be estimated from existing exp...
Gamma-radiation initiated addition of allylbenzene to the morpholine Nesterov, SV; Kucukyavuz, S; Önal, Ahmet Muhtar (Springer Science and Business Media LLC, 1999-10-01) Radiation induced addition of allylbenzene to morpholine in liquid state was investigated by UV-, IR-spectroscopy and GS/mass spectrometry. Conversion of monomer depends on its initial concentration in the solution and this value is maximum for 0.05M solution. Radiation chemical yield of the product, G(prod), increases with concentration of allylbenzene and for 0.15M solution it is equal approximately 9.7 molec/100 eV. This value points on chain character of the process. Final product was identified by elec...
Efficiency calibration and summation effects in gamma-ray spectrometry Erten, Hatice Nilay; Aksoyoğlu, Şebnem; Göktürk, Hal (Springer Science and Business Media LLC, 1988-11) recise, absolute γ-ray efficiences (∈ γ ) and total efficiences (∈ T), have been measured at various distances from the detector, using a set of standards. The observed linear variation of∈ γ and∈ T as well as∈ γ /∈ T with Eγ and1/d−−√ provides a simple means of interpolation and extrapolation. Experimental coincidence summation effects were determined for various nuclides and compared with calculated values. The results are found to be in good agreement with each other.
