Measurement of mass attenuation coefficients by Si(Li), NaI(Tl) and Cd(Tl) detectors
(Transworld Research Network, 2012-01-01)
Mass attenuation coefficients of the some elements were
determined for two photon energies using different three detectors.
The samples were irradiated using 10 mCi Cd-109 and 100 mCi
Am-241 radioactive point sources. ...
Kesirli dereceli kontrol sistemlerinde tamsayı dereceli yaklaşım metotlarının incelenmesi

Determination of L X-ray fluorescence parameters for Ho, Lu, W, Hg and Bi
(Elsevier Ltd, 2014-07-01)
In this work, L X-ray fluorescence cross sections, L sub-shell fluorescence yields and level widths and radiative vacancy transfer probabilities of L sub-shells to Mi, Ni and Oi sub-shells were measured for the elements ...
Measurement of magnetic quadrupole-electric dipole mixing ratios and angular distribution parameters in atomic inner-shell transitions
(Materials Science and Technology Conference and Exhibition 2013, MS and T 2013, 2013-10-27)
In studies of the angular distribution of the magnetic L 3-subshell X-ray transitions it has been generally assumed that observed radiations consist of pure electric dipole transitions and contributions from higher-order ...
Essential oil composition of two Centaurea L. (Asteraceae) species from Turkey.
(2015)
In this study, aerial parts of C. cynaus L. and C. depressa Bieb. were analysed by HS-SPME/GC-MS. As a result
thirty five and thirty seven components were identified representing 92.3% and 91.1% of the oil, respectively ...
Essential oil composition of wiedemannia fisch. & C.A. Mey. genus from Turkey: a chemotaxonomic approach
(2014-12-23)
The essential oils water distilled aerial parts of Wiedemannia orientalis Fisch. & C.A.Mey.
and Wiedemannia multifida (L.) Benth. (Lamiaceae) were investigated by GC and GC-MS. Thirty seven and
thirty six compounds were ...
Determination of K-shell absorption jump factors and jump ratios for La2O3, Ce and Gd using two different methods
(2015-02-01)
The K shell absorption jump factors and jump ratios for La2O3, Ce and Gd samples have been determined using the gamma or X-ray attenuation and EDXRF methods. It is the first time that the K shell absorption jump factor and ...
Intelligent design of the post-listening tasks in multimedia listening software
(2015)
The objective of this chapter is to clearly demonstrate through concrete examples how affective and efficient post-listening tasks for autonomous intermediate and upper-intermediate (intermediate) language learners can be ...
Learners’ perceptions towards interactive multimedia environments
(2014)
In this study, 113 participants’ (N= 113) perceptions of a specific Interactive Multimedia Environment (IME) (i.e. World Talk English software) and any differences between their perceptions in terms of gender, age, job and ...
