Abstract

The 36 meter SANS BATAN spectrometer (SMARTer) in Serpong Indonesia has been developed for simultaneous and automatic measurements. The existing motor controller of ISA (Industry Standard Architecture) interface was replaced by the programmable motor controller of PCI (Peripheral Component Interconnect) interface, since it has speed and interrupt-sharing advantages, to drive all stepper motors for collimator, pinhole, and detector movements of the spectrometer. The recent development makes all motors moved and controlled simultaneously in setting up the instrument configuration before performing the experiment. Along with that improvement, the data acquisition software has been also developed to drive the beam stopper movement in two directions as well as to read the absolute collimator and detector positions, to acquire neutron counts on the monitor and the main detector, and also to control automatically up to 12 sample positions of the sample changer. The collected neutron counts is displayed in real time on the main monitor window, and the counts is saved in a special format for further data reduction and analysis. The developed data acquisition software has been implemented and performed for experiment that use preset time or preset count mode, and the automatic sample changer.Received: 08 November 2013; Revised: 23 December 2013; Accepted: 27 December 2013

Abstract

The aim of this researchwas to formulate mangosteen (Garcinia mangostana L.) pericarp extract into oil-in-water (O/W) cream which stable and durable. In order to improve the shelf life durability of the formula, the irradiation of formula using gamma rays from cobalt-60 was done. The concentrations of extract were varied to 1, 2 and 3% and were irradiated by gamma rays with doses of 5, 7.5 and 10 kGy. Physicochemical and microbiological properties of these formulas were carried outfor 90 days stored at 30 ± 2°C and 40 ± 2°C. It was found that both of physicochemical and microbiological properties of the formulas were changed by extract concentrations and after irradiation. The irradiated formulas with dose up to 7.5 kGy, which were stored at 30 ± 2°C and 40 ± 2°C, presented acceptable physicochemical and microbiological stability for at least 90 days. Analysis by TLC (Thin Layer Chromatography)-densitometry to study decomposition of G. mangostana pericarp extract cream formulas was carried out 24 h after preparation and 90 day after storage. The result of TLC-densitometry analysis showed that G. mangostana pericarp extract in the cream formulas did not develope significant decomposition after 90 days of storage. Decontamination dose for all formulas was found to be about 7.5 kGy. At this condition, the bacteria and mold-yeast have been killed, without reducing the antioxidant activity.Received: 24 November 2013; Revised: 20 December 2013; Accepted: 26 December 2013

Abstract

Poly(4-Hydroxybutirat)p4hb, Poly(butylene succinate-co-adipate) PBSA and Poly(e-caprolactone) PCL were electron beam (EB)-irradiated. Poly(4-Hydroxybutirat) was irradiated without any polyfunctional monomers (PFM). While  PBSA and  PCL were irradiated in the presence of polyfunctional monomers such asTrimethallyl isocyanurate (TMAIC), Polyethyleneglycol dimethacrylate (2G, 4G), Trimethylolpropane trimethacrylate (TMPT) and Tetramethylolmethane tetraacrylate (A-TMMT) at ambient temperature. Aim of the study is to improve the properties of biodegradable polyester.  It was pointed out that crosslinking yield of P4HB (6.39% gel)was formed at dose of 90 kGy irradiated in vacuum conditions. Radiation degradation promoted, when P4HB was irradiated in air. The optimum crosslinking yield of PCL and PBSA respectively, were formed in the presence of 1% TMAIC at dose of 50 kGy. The biodegradability of the crosslinked PBSA evaluated by soil burial test is slightly retarded by increasing crosslinking yields.Received: 20 November 2013; Revised: 27 December 2013; Accepted: 31 December 2013

Abstract

Radiological protection of the environment has been intensively discussed in recent years. Much progress has been made recently with regard to the development of models: (i) to estimate the uptake of radionuclides by flora and fauna in different habitats and ecosystems; (ii) to calculate internal and external exposures for a wide range of terrestrial and aquatic organisms; and (iii) in investigating and analyzing the effects of radiation exposures to biota. This paper gives an overview of the current status of this work. Furthermore, the current status of the integration of environmental protection into the radiation protection system is also summarized.Received: 8 November 2013; Revised: 23 December 2013; Accepted: 30 December 2013

Abstract

The motion of a nucleon in q-deformed Eckart potential field coupled with Yukawa-type tensor potential is described by using Dirac equation. The bound state solutions of Dirac equation for q-deformed Eckart potential with Yukawa-type tensor potential under exact spin- and pseudospin-symmetric limit are obtained using finite Romanovski polynomials. The approximate relativistic energy spectra are exactly obtained within the approximation scheme of centrifugal term. The relativistic energy is negative for pseudospin symmetry and positive for spin symmetry. The radial component of Dirac spinors are obtained in terms of Romanovski polynomials under exact spin- and pseudospin-symmetric conditions. The relativistic energy spectrum for the exact spin-symmetric case reduces to non-relativistic energy spectrum in the non-relativistic limit.Received: 23 October 2013; Revised: 02 November 2013 Accepted: 10 November 2013

Abstract

99mTc-glutathione (99mTc-GSH) is a radiopharmaceuticalwhich is potentially used as a cancer diagnostic kit. As with other radiopharmaceuticals, before applied in humans, including in clinical trials, 99mTc-GSH needs to go through a series of preclinical trials in animal first. The preclinical trial which has been done in this study is the evaluation of the biological test on biodistribution and imaging of white rats (Rattus norvegicus) which had been induced with cancer. The aims of this research were to obtain data on biodistribution and to image the biodistribution of 99mTc-GSH at 1 hour, 3 hours, and 24 hours post-injection. Biodistribution resultsof 99mTc-GSHin the cancer at the timesof 1 hour, 3 hours, and 24 hours after injection were 0.66% ID/g, 0.95% ID/g, and 0.06% ID/g, respectively. This result shows that the highest accumulation of 99mTc-GSH in canceroccur at 3 hours post-injection. This value indicates that the optimal accumulation of the 99mTc-GSH occur in this time interval.In addition, the results of imaging test also show that the accumulation capacity of 99mTc-GSHin cancer is also highest at 3 hours post-injection.Received:16 January 2013; Revised:15 October 2013; Accepted: 16 October 2013

Abstract

Chromosome aberration is a biomarker to predict the level of cell damage caused by exposure to ionizing radiation on human body. Dicentric chromosome is a specific chromosome aberration caused by ionizing radiation and is used as a gold standard biodosimetry of individuals over exposed to ionizing radiation.In radiation accident the dicentric assays has been applied as biological dosimetry to estimate  radiation absorbed dose and also to confirm the radiation dose received to radiation workers.The purpose of this study was to generate a dose response curve of chromosome aberration (dicentric) in human lymphocyte inducedbygamma radiation. Peripheral blood samplesfrom three non smoking healthy volunteers aged between 25-48 years old with informed consent were irradiated with dose between 0.1-4.0Gy and a control using gamma teletherapy source. The culture procedure was conducted following the IAEA standard procedures with slight modifications. Analysis of dose-response curves used was LQ model Y = a + αD + βD2. The result showed that α and β values of the curve obtained were 0.018± 0.006 and 0.013 ± 0.002,respectively. Dose response calibration curve for dicentric chromosome aberrations in human lymphocytes induced by gamma-radiation fitted to linear quadratic model. In order to apply the dose response curve of chromosome aberration disentric for biodosimetry, this standar curve still need to be validatedReceived: 8 November 2013; Revised: 27 December 2013; Accepted: 31 December 2013
