Following the demise of Mun Sŏn-myŏng in 2012, the South Korean Unification Movement has entered an era of female leadership. Mun!s widowed wife, Han Hak-cha, rose to become the group!s sole new leader. Drawing on a distinct (co-)messianic narrative, while resuming on the givenmillenarian trajectory – both chiefly shaped byMun – Han successfully coped with the theological and organisational cha...
In this research, the effect of two process control agent: methanol (liquid state) and stearicacid (solid state) on mechanical alloying process of Ti and Al with equal at%(Ti50Al50) wereinvestigated. Phase transformation at presence of two PCA was: at first, powder mixture wastransformed to a metastable solid solution of Al in Ti lattice (disordered hcp) and then transformed toamorphous phase w...
Air plasma spray (APS) process is used to produce high density and flowability spherical powders. Phase transformation that occurred in this process isn’t well known. In this paper, the YSZ powders have been sprayed in water to investigate the morphology changes and phase transformations via air plasma spray (APS) method. Phase analysis of powders was examined by XRD and the crystallite size an...
In this work, we study the lithiation behaviours of both porous silicon (Si) nanoparticles and porous Si nanowires by in situ and ex situ transmission electron microscopy (TEM) and compare them with solid Si nanoparticles and nanowires. The in situ TEM observation reveals that the critical fracture diameter of porous Si particles reaches up to 1.52 μm, which is much larger than the previously r...
abstract a fundamental study of “historio-graphic metafiction” and “literary genres”, as introduced in “new historical philosophy”, and tracing them in the works of julian barnes having studied the two novels, the porcupine and arthur & george, by julian barnes, the researcher has applied linda hutcheon’s historio-graphic metafictional theories to them. the thesis is divided into five cha...
Background: One of the important issues in aging is sarcopenia characterized by muscle mass and function reduction. The present study investigated the effect of high intensity interval resistance training (HIIRT) on muscular parameters in sarcopenic elderly women. Methods: A total of 30 sarcopenic women aged 60 to 70 years (appendicular skeletal muscle mass index<6.76 kg/m2, hand grip<20 kg) w...
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
the aim of the present study was to investigate the potential of nanoemulsion formulation for topical delivery of clobetasol propionate (cp) using algal oil (containing omega-3 fatty acids) as the oil phase. cp has anti-inflammatory, immunomodulatory and antiproliferative activities. however, its clinical use is restricted to some extent due to its poor permeability across the skin. algal oil w...
