Design of pre-listening tasks in hypermedia environments
(2015)
In this article, firstly the definition of autonomy will be slightly
touched on. Secondly, the categorisation of autonomy will be briefly made.
Mainly and finally, what need to be taken into account in order to be able ...
Measurement of L3 Sub-Shell to M, N, O Shell Radiative Vacancy Transfer Probabilities for Ho, Lu and Hg Elements
(IPCAP 2016, 2016-02-27)
The radiative vacancy transfer probabilities from L3 sub-shell to M, N, O sub-shells were measured for the elements Ho, Lu and Hg. To obtain related parameters, we used 59.54 keV gamma photons of 241Am radioactive source. ...
Determination of K Shell Fluorescence Parameters for Some Elements in the Atomic Number Range 50≤Z≤60
(IPCAP 2016, 2016-02-27)
The fluorescence cross sections, fluorescence yields, level widths and intensity ratio for some elements in the atomic range 50≤Z≤60 were measured. The targets were excited using photons of 59.54 keV emitted from an Am-241 ...
Determination of K-Li Sub-Shell, Total K-L and Total K-M shell Vacancy Transfer Probabilities for Europium, Gadolinium and Terbium
(IPCAP 2016, 2016-02-27)
There are different ways to produce a vacancy in an atom such as photoelectric effect, Compton scattering, triplet production, charged particle Coulomb interaction, internal conversion, electron capture, positron annihilation ...
The Chemical Effect on the Fluorescence Yield Parameters of Ligands of Malonic Acid[(Ch2(Cooh)2)] and Phenylmalonic Acid [C6h5nch(Cooh)2]
(IPCAP 2016, 2016-02-27)
In the present work, the ligands of Ligands of Malonic Acid[(CH2(COOH)2)] and Phenylmalonic Acid [C6H5NCH(COOH)2] derivatives were obtained by the slow evaporation and neutralization method. The ligands were coordinated ...
Measurement of L subshell fluorescence yields for high-Z elements excited by 22.6keV photons
(Elsevier Ltd., 2012-03-01)
The σ L1, σ L2 and σ L3 subshell X-ray production cross sections for U, Th, Bi, Pb, Tl, Hg, Au, Pt, Os, W, Ta, Lu, Yb and Er have been measured at 22.6keV incident photon energy. The measurements were performed using a ...
The inclusion and design of cultural differences in Interactive multimedia environments
(2014)
A concern for social justice and the inclusion of cultural differences as a requirement of social justice in all learning materials, whether they are in the form of conventional materials or Interactive Multimedia Environments ...
Intelligent design of captions in interactive multimedia listening environments
(2015)
In this chapter, 48 language learners’ perceptions towards the presence of captions at the first listening (i.e. the while listening stage) in an IME that aimed to enhance the language learners’ listening skills as a part ...
Design of the while-listening tasks in autonomous hypermedia environments
(2015)
In this article, firstly the definition of autonomy will be briefly
touched on. Secondly, the categorisation of autonomy will be shortly
made. Mainly, what needs to be taken into account in order to be able to

Determination of K shell absorption parameters for some lanthanides using the X-ray attenuation method
(nrcresearch press, 2015-07-27)
The total attenuation cross section at the K edge, absorption jump ratio, jump factor, Davisson–Kirchner ratio, and oscillator strength parameters for the K shell were determined by measuring the total attenuation cross ...
