In Vitro Cytotoxic Activity of Silver Nano Particle Biosynthesized from Colpomenia Sinuosa and Halymenia Poryphyroides Using DLA and EAC Cell Lines
This study was conducted to investigate the invitro cytotoxic activity of silver nano particles biosynthesized from Colpomenia sinuosa and Halymenia poryphyroides using DLA and EAC cell lines by tryphan blue dye exclusion technique and MTT assay using Mouse L929 cell lines (Lungs fibroblast). The results of the trypan…
Editorial (Thematic Issue: “Cell-penetrating Peptides and Drug Delivery”)
In recent years biomacromolecular drugs including proteins and nucleic acids have been emerging among the most promising therapeutics and globally recognized as one of the most cutting-edge areas of drug research. However, the nature of strong hydrophilicity and high molecular weight creates a formidable barrier for t…
The magnitude of the magnetic exchange interaction in the heavy fermion antiferromagnet CeRhIn$_5$
We have used high-resolution neutron spectroscopy experiments to determine the complete spin wave spectrum of the heavy fermion antiferromagnet CeRhIn$_5$. The spin wave dispersion can be quantitatively reproduced with a simple $J_1$-$J_2$ model that also naturally explains the magnetic spin-spiral ground state of CeR…
KENS Shielding Experiment (2): Measurement of the Neutron Spatial Distribution inside and outside of a Concrete Shield using an Activation Foil and an Imaging Plate Technique
The spatial distribution of neutrons inside and outside the concrete shield of KENS was measured by the combined use of activation detectors and an imaging plate. Aluminium and gold foils were used for neutron flux measurements of both high-energy and thermal neutrons, respectively. The obtained results concerning att…
Status of Angular Distribution Measurements of Photo-Neutron Yields from Cu, Sn, and Pb Targets Irradiated by 2 GeV Electrons
The study of differential photo-neutron yields by the irradiation of 2 GeV electrons has been carried out. In this extended study of previous measurements, which were done at the angle of 90° relative to incident electrons, the differential photo-neutron yield was obtained at two other angles of 48° and 140° to study…
Experimental Study on Induced Radioactivity in Boron-doped Low Activation Concrete for DT Fusion Reactors
In order to investigate applicability of the boron-doped low activation concrete to the DT nuclear fusion reactor, DT neutron irradiation tests were performed together with the standard sample usin...
Dependence of the Glow Curve Structure for a New KLT-300(LiF:Mg,Cu,Na,Si) TL Detector on the Dopants Concentration
A new TL detector KLT-300 (KAERI LiF TL detector doped with Mg, Cu, Na, Si) for personal and medical monitoring purposes was recently developed at KAERI (Korea Atomic Energy Research Institute). The main parameters in preparation of the detector were the concentration of the dopants. In this research, the investigatio…
Procurement of wood energy feedstocks
The harvesting and procurement of wood is the first step in the supply chain of utilizing forest biomass for renewable energy. In order for the use of wood as an energy feedstock to be practical, it must not only be physically available, but must also be economically feasible to acquire and deliver the material to a po…

Grain Size Effect of Tooth Enamel to Electron Paramagnetic Resonance Spectrum
Electron Paramagnetic Resonance (EPR) spectroscopy is one of the methods applicable to retrospective dosimetry. The retrospective dosimetry is a part of dose reconstruction for estimation of exposed dose occurred years before the estimation. As a biosample, tooth enamel is known as to show good sensitivity to the abso…
Influence of vermiculite particles on antioxidant properties of cultural medium of Bacillus subtilis IMV V-7023
It is shown that in the process of cultivation of Bacillus subtilis IMV V-7023 in the medium with vermiculite (1.5-5.0 g/l) one can observe the oppressing of some indexes of antioxidant properties of cultural medium of bacteria. In particular, a decline of hydroxyl radical scavenging activity in the Fenton reaction by…

Crystallization and preliminary X-ray analysis of the C-terminal fragment of Ski7 fromSaccharomyces cerevisiae
Ski7 (superkiller protein 7) plays a critical role in the mRNA surveillance pathway. The C-terminal fragment of Ski7 (residues 520-747) from Saccharomyces cerevisiae was heterologously expressed in Escherichia coli and purified to homogeneity. It was successfully crystallized and preliminary X-ray data were collected…
Investigation of physico-mechanical properties of natural palm fiber reinforced polyvinyl chloride composites
Fiber reinforced polymer composites played a dominant role in a variety of applications for their high specific strength and modulus. The present work describes the effects of palm fiber addition on physico-mechanical properties of polyvinyl chloride (PVC) composites. The tensile strength and Youngs modulus of the fa…
Resistivity anisotropy of the misfit layer compound (SmS)1.25 TiS2
BACKGROUND: The misfit layer compound (SmS)1.25 TiS2 has a layered structure which consists on an alternating sequence of one |SmS| bi-layer adopting a NaCl distorted structure and one |TiS2| tri-layer with the Ti atoms plane sandwiched by two sulfur ones and the Ti atoms octahedrally coordinated. Stacking is along th…
Compact Triple Band Metamaterial Antenna Based on Modified Electric-field Coupled-LC Resonator
In this paper, a compact triple band metamaterial antenna based on modified electric-field coupled (ELC) resonator is presented. The modification to the conventional ELC is achieved by the use of strip lines to enhance the capacitive coupling of the capacitive gaps and a stub printed at the back of the resonator. The…
On wafer thermal characterization of miniature gallium arsenide microcoolers with thermal loading from DC probes
ABSTRACT Miniature aluminium gallium arsenide/gallium arsenide (AlGaAs/GaAs) coolers were fabricated on wafer, enabling different contact geometries to be realized in the same process run. To individually DC bias the microcooler, microprobes were used leading to thermal loading of the cooler. A simple experimental tec…
Confined modes on a meta-surface
Meta–surfaces or 2D metamaterials are generally considered in the far-field. Because of their resonant properties, they possess also an interesting band structure in the near-field. A meta–surface made of a set of parallel nano- wires deposited on a surface was studied. Bloch waves localized on the surface exist in th…
