Two fundamental concerns must be addressed when attempting to isolate low-level waste in a disposal facility on land. The first concern is isolating the waste from water, or hydrologic isolation. The second is preventing movement of the radionuclides out of the disposal facility, or radionuclide migration. Particularl…
In Brief A methodology is provided to determine how much removable surface contamination can be detected on a large area wipe by surveying the wipe with a portable survey instrument. Equations are provided to relate levels of removable surface contamination to survey instrument readings from a wipe, considering the ef…
The photon interaction parameters such as mass attenuation coefficient (μ/ρ), effective atomic number (Z eff) and effective electron density (N el) must be identical for the phantom material and their tissue. In the present study, the μ/ρ, Z eff, and N el for muscle, breast, lung tissue have been computed, and their s…
Colloidal system is a dispersion wherein dispersed particles i.e. internal phase are distributed uniformly in a dispersion medium i.e. external phase or continuous phase. The size range consume the nanometer (10–9m) to micrometer (10–6m) rang.
Three new triphenylamine-containing aromatic diacid monomers, 4,4'-dicarboxy-4''-isopropyl-triphenylamine (Ma), 4,4'-dicarboxy-2'4 ' A series of poly(amine-amide)s were prepared by the direct phosphorylation polycondensation from the newly synthesized diacid monomers with various aromatic diamines. FTIR, 1 H and 13 C…
Mini-tablets are tablets with a diameter equal to or smaller than 2–3 mm. In the present work both immediate and sustained release mini-tablet of terbutaline sulphate was formulated and evaluated for different pre and post compression parameters. Immediate release tablets were formulated by adding CCS and SSG as super…
The present study was conducted to select a suitable maintenance medium for the maintenance of the multiple analogue resistant mutant and also to determination of its auxotrophic requirements. Among the three medium studied, the strain maintained its constant rate of production of L-methionine for many generations(stu…
In 2013, Macromolecular Reaction Engineering (MRE) received a new record number of submissions with a more than 20% increase compared with the previous year, and also achieved an ISI Impact Factor of 1.638. These facts, together with numerous positive and encouraging comments from leading experts in the field, confirm…
La laguna Mulitas es una laguna permanente situada en el partido de 25 de Mayo, Pcia.de Buenos Aires. La misma presenta un estado natural eutrófico[1] , pero debido a la intensidad de uso de suelo en la cuenca su estado actual es hipereutrófica[2].En su estado natural, funciona como un sistema arreico cuyo último punt…
A new blue‐emitting phosphor of Eu2+‐activated hexa‐aluminate CaZrBAl9O18 was synthesized by a conventional solid‐state reaction method. The crystalline phase formation was confirmed by X‐ray powder diffraction (XRD) measurements. The photoluminescence excitation and emission spectra, the luminescence decay curves and…
In this study, we synthesized a new fluorescent polypyridyl dye 2 containing a 2,2'-bipyridine in the center and two 2,2':6',2"-terpyridines at both ends. When exposed to various metal ions, the dye 2 showed selective fluorescence responses. In the presence of $Cu^{2+}$ and $Ni^{2+}$ , it exhibited a highly effective…
AlN epilayers were grown on a c-plane sapphire substrate using hydride vapor phase epitaxy (HVPE). A series of AlN epilayers were grown at $1120^{\circ}C$ with V/III ratios 1.5, 2.5 and 3.5, and the influence of V/III ratio on their properties was investigated. As the V/III ratio was increased, the surface roughness (…
The β-sheet of muscle fatty acid binding protein of Locusta migratoria (Lm-FABP) was modeled by employing 2-D NMR data and the Rigid Body Assembly method. The model shows the β-sheet to comprise ten β-strands arranged anti-parallel to each other. There is a β-bulge between Ser 13 and Gln 14 which is a difference from…
Cotton fabrics treated with hybrid materials were developed and prepared. A halogen-free flame retardant and an aromatic amide were blended and applied to cotton fabrics. Thermal and physical properties of the treated cotton fabrics were investigated. The surface of the pure and coated cotton fabrics was characterized…
We demonstrated size control of Au nanoparticles by heat treatment and their use as a catalyst for single-walled carbon nanotube (SWNTs) growth with narrow size distribution. We used uniformly sized Au nanoparticles from commercial Au colloid, and intentionally decreased their size through heat treatment at 800 oC und…
The behavior of polyethylene glycol (PEG) molecules at an oscillating solid-liquid interface was examined using a quartz crystal microbalance (QCM). The number-average molecular weights (Mn) of PEG molecules were systematically varied. This study revealed that the shift in the energy dissipation factor, ΔD, of the QCM…
ABSTR AK Daya tahan beton yang rendah terhadap gaya tarik dan geser dapat ditingkatkan dengan menambahkan fiber pada beton. Gagasan utamanya adalah memberi tulangan mikro pada beton dengan fiber yang disebar secara merata. Hal ini akan mencegah retak awal pada beton, sehingga kemampuan beton untuk menahan gaya lentur,…

EVALUASI KESIAPSIAGAN NUKLIR DI INSTALASI RADIUOMETALURGI BERDASARKAN PERKA BAPETEN NOMOR 1 TAHUN 2010. Telah dilakukan evaluasi kesiapsiagan nuklir Instalasi Radiometalurgi (IRM) berdasarkan Perka BAPETEN nomor 1 tahun 2010. Perka BAPETEN nomor 1 tahun 2010 pasal 50 menyatakan bahwa pada saat peraturan ini mulai berl…
Zinc oxide (ZnO) that contains non-magnetic ionic dopants, such as nitrogen (N)-doped zinc oxide (ZnO:N), has been observed to exhibit ferromagnetism. Ferromagnetism is proposed to arise from the Coulomb excitation in the localized states that is induced by the oxygen vacancy, V O. A model based on the Coulomb excitat…
