Determination of Kα,β excitation factors in thin target for selected elements from Y to Te at 59.54 keV excitation energy
(Elsevier, 2015-10-22)
The paper presents the first measurements of the Kα and Kβ excitation factors for some selected elements from Y to Te. To determine the Kα and Kβ excitation factors, the experimental values of K shell X-ray production cross ...
Tertiary Students’ ICT Self-efficacy Beliefs and the Factors Affecting their ICT-use.
(2015)
This study looked at tertiary (i.e. undergraduate /a four-year degree) students’ information and communication technology (ICT) self-efficacy beliefs and their level in use of certain common programmes at a newly established ...
Preface
(2015)
Not only are we, as educators and materials developers, living in a digital age, but we are also required to meet the needs of today’s learners who are in general digitally fluent and competitive, - as they are born into ...
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 ...
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
design ...
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 ...
Listening, multimedia and optimum design
(2015)
Listening is “…a term used in language studies and language education to refer … to a set of cognitive
interactions involved in oral language processing” (Rost, 1994, p. 3778). It is also added that listening is
“... the ...
Studies on effective atomic numbers, electron densities from mass attenuation coefficients near the K edge in some samarium compounds
(Elsevier Ltd., 2015-07)
The effective atomic numbers and electron densities of some samarium compounds were determined using the experimental total mass attenuation coefficient values near the K edge in the X-ray energy range from 36.847 up to ...
Measurements of K shell absorption jump factors and jump ratios using EDXRF technique
(2015-04-10)
In the present work, the K-shell absorption jump factors and jump ratios for 30 elements between Ti (Z = 22) and Er (Z = 68) were measured by energy dispersive X-ray fluorescence (EDXRF) technique. The jump factors and ...
