Abstract

The temporal behavior of gadolinium (Gd) laser-produced plasmas has been studied using a modified grazing incidence spectrometer which allows to capture the evolution of the plasma with spectral and temporal resolution of 0.1 nm and 1 ns, respectively. Experimental results indicate that the soft X-ray emission follows the temporal behavior of the laser pulse at high laser power density of Ф = 4.4×1012 W/cm2 in which the soft X-ray emission lasts for 7.5 ns (at FWHM) whereas at Ф = 5.4×1011 W/cm2 and Ф = 7.6×1010 W/cm2 the emission lasts for only 4 ns and 2.5 ns respectively,these are shorter than laser pulse duration due to lower electron temperatures achieved in the plasma generation. Lower Gd ion stages ranging from Gd11+ – Gd14+ are also found to contribute to the spectral emission over time.Received: 08 November 2013; Revised: 09 May 2014; Accepted: 09 May 2014

Abstract

The research related to thermal management has been significantly inreased, especially for NPP safety. The use of passive cooling systems both during the accident and operation become reliable in the advanced reactor safety systems. Therefore it should be enhanced through experimental studies to investigate heat transfer phenomenon of the heat decay in transient cooling condition.An investigation has been performed through experiment using an NC-Queen apparatusconstructed with rectangular loop. Piping were consisting of tubes of SS316L with diameter, length, and width of 3/4 inch, 2.7 m, and 0.5 m respectively. The height between heater and cooler was 1.4 m. The experiment used initial water temperature  at 70oC, 80oC, and 90oC in heater area. Transient temperature was used as experimental data to calculate water mass flow rate. The results showed that the temperature in heater area and cooler area were decreasing of about 90.6% and 95.7% at initial temperatur of 80oC, and of about 71.1% and 59.4% at initial temperature of 70oC. Those results were at higher initial temperature of 90oC compared with the initial temperature of 90oC. The average of water mass flow rate increased 81.03% from initial temperatur of 70oC. It was shown that the averages of removed heat in every second from water due to heat loss and cooler,were 3.51 watts, 5.06 watts and 6.85 watts respectively. The initial condition of heat stored in the water was quite different, but to the cooler heat removal capacity and heat loss was almost the same.Received: 10 November 2014; Revised: 23 December 2014: 24 December 2014

Abstract

Given the facts that Indonesia has suitable environment condition to survival, reproduction and development of the principal mosquito vector for dengue virus, Aedes aegypti, the transmission of dengue virus does routinely occur every year. The sterile insect technique (SIT) as one of the techniques in area-wide integrated pest management (AW-IPM) has been developed to control Aedes aegypti population since 2004. The first 5 years of the program (2004-2009) was focused on mass rearing facility establishment. The lab-work study for the entomological data and field trials were performed in 2010-2014. In 2014-2019, the program was addressed to enhance the mass rearing facility to increase sterile male production and strengthening the networking throughout the involvement in the regional and interregional program coordinated by International Atomic Energy Agency (IAEA). The main future challenge of the SIT program against Aedes aegypti is developing the capacity building and strong commitment of all stakeholders i.e. the Ministry of Health, the universities, the research institutes and the public. In the future work plan, the pilot project design to proof the concept of the SIT is strongly recommended to obtain a firm, unbiased and strong results as the consideration for the decision maker to create the Aedes control program in Indonesia.

Abstract

A Penning-type ion source for a cyclotron producing PET radioisotopes has been made. To determine the performance of the ion source for further developments, an investigation on the operating parameters has been conducted. The investigation was carried out by experiments on an ion source test device. The investigated operating parameters were the puller voltage, the magnetic field, the hydrogen gas flow rate, and the cathode current. The results showed that the puller voltage was the most sensitive parameter to change ion beam current, and at a voltage of 8 kV an ion beam current of 35 µA was obtained. The puller voltage is still likely to be raised if the current beam is to be increased. Increasing the magnetic field beyond approximately 450 gauss caused the ion beam to saturate. It was obtained that a moderate range of gas flow rate on the value of 5-10 cc/min, producing a high beam current with no significant effect to decrease a vacuum level. Cathode current magnitudes of up to 1 mA significantly affect the beam current, while above this value the beam current tends to be constantReceived: 04 October 2014; Revised: 28 April 2015; Accepted: 05May 2015

Abstract

The diagnostic reference levels form an efficient, concise, and powerful standard for optimizing the radiation protection of a patient. With an aim to contribute toward the establishment of the Indonesian National Diagnostic Reference Levels (NDRLs), a nationwide survey of the entrance surface doses received by adult patients during the most typical X-ray examinations has been performed. A number of 44 hospitals in 21 cities located in Java, Bali, Sumatera, Kalimantan, and Sulawesi islands were selected randomly to participate in this survey. Eight most common adult X-ray examinations in 13 projections, as well as four children X-ray examinations in six projections, were included in the list of procedures under consideration. Hospitals of different sizes and levels using different X-ray machines were represented in the survey. Standard thermoluminescence dosemeters were applied to measure entrance surface dose (ESD). A total of 1493 patients, consisting of 1208 adults and 285 children, were included in this study. The data were analyzed statistically and the minimum, median, mean, maximum, first quartile, and third quartile values of ESDs were reported. The ESDs calculated (third quartile) for adults varied from 0.18 mGy (for extremities AP) to 5.84 mGy (for lumbar spine LAT), and for children they varied from 0.16 mGy (for chest AP/PA) to 1.46 mGy (for skull AP/PA). Considering the geographic spread and size of Indonesia, those third quartile values calculated can only be regarded as preliminary DRL values for Indonesia. Compared with data from other countries, the calculated ESDs in this study are in general lower than the ESDs in those countries.Received: 16 November 2015; Revised: 27 April 2016; Accepted: 9 May 2016

Abstract

Most of diabetes patients have type 2 diabetes mellitus or non insulin dependent diabetes mellitus. Treatment of type 2 diabetes mellitus can be conducted by inhibiting the α-glucosidase enzyme which converts carbohydrates into glucose. Sulochrin is one of the potential compounds which can inhibit the function of α-glucosidase enzyme. This study was carried out to obtain data of sulochrin binding with α-glucosidase enzyme as α-glucosidase inhibitor using Radioligand Binding Assay (RBA) method. The primary reagent required in RBA is the labeled radioactive ligand (radioligand). In this study, the radioligand was sulochrin-125I. Prior to the sulochrin-125I synthesis, sulochrin-I was synthesized. Sulochrin-I and sulochrin-125I were synthesized and their bindings were studied using RBA. The  molecular formula of the synthesized Sulochrin-I is C17H15O7I and its molecular weight is 457.9940. The sulochrin-125I was synthesized from sulochrin-I by isotope exchange method. From RBA, the dissociation constant (Kd) and the maximum binding (Bmax) were found as 26.316 nM and 9.302 nM, respectively. The low Kd indicates that sulochrin is capable of binding to α-glucosidase.Received: 08 November 2013; Revised: 28 February 2014; Accepted: 28 March 2014

Abstract

Some efforts have been done to cope with coastal erosion and rob in Sayung Coast including mangrove plantation, hybrid engineering (HE), and hard structure protection. However, those efforts are not considered to be the best solution in reducing the impacts of the hazards. This study aimed to determine the sediment accumulation rates based on natural isotopes 210Pb dating and hydro-oceanographic modeling technique. According to 210Pb analysis, we calculated the sediment accumulation rates at Surodadi and Timbulsloko of 0.145 cm/year and 0.06 cm/year, respectively. The sediment compositions are dominated by terrestrial sediment typified by clay deposits. The sedimentary rate average of Sayung Coast prior to HE installation (2011-2013) was 0.195 cm/year. The rate of sediment accumulation rose to around 0.4 cm/year in 2016 in accordance with the increase of Mangrove area from around 409 hectares in 2013 to about 455.79 hectares in 2015. The increase of sedimentary rate recent years became an evidence that mitigation efforts to reduce abrasion temporarily succeeded.
