Abstract
Introduction Stemmed humeral implants have represented the gold standard in total shoulder arthroplasty (TSA) for decades. Like many other joints, the latest trends in TSA designs aim at bone preservation. Current studies have demonstrated that native proximal humeral bone stresses are most closely mimicked by stemless implants. Nevertheless, there are concerns about the long-term performance of stemless designs. The aim of the present study was to evaluate the long-term radiographic changes at the proximal humerus in anatomical stemless press-fit TSA.
Materials and Methods Between 2008 and 2010, 48 shoulders in 43 patients were resurfaced using an anatomic stemless shoulder prosthesis (TESS, Biomet). Thirty shoulders in twenty-five patients who were aged 65.7 ± 9.9 (34 to 82) years were available for clinical and radiographic review at a mean follow-up of 94.0 ± 8.9 (78 to 110) months.
Results Radiographic changes of the proximal humerus due to stress shielding were found in 38.4% of the stemless TESS implants. Mild stress shielding accounted for 80% of the observed radiographic changes. Radiographs exhibited stable fixation of the stemless humeral press-fit implant at early and late follow-up. In contrast, radiolucent lines at the glenoid implant were found in 96.1% of the cases. Irrespective of the degree of radiographic changes, clinical scores (VAS, Quick-DASH, Constant score) significantly improved at follow-up.
Conclusions The anatomic stemless press-fit implant seems to be favorable in terms of implant-related stress shielding. Clinical outcome was not affected by radiographic changes, demonstrating an 8-year clinical performance that seems to be comparable to conventional stemmed TSA.

ZusammenfassungDas Spektrum der Zwangsstörungen (OCD) beinhaltet schwere, stark einschränkende Zustandsbilder. Zwangsstörungen entwickeln sich in der Regel in der späten Adoleszenz bzw. im frühen Erwachsenenalter und nehmen einen chronischen Verlauf, sofern keine Behandlung erfolgt. Das Konzept der OCD zeigt große Varianz entsprechend kultureller und historischer Kontexte. Unter Geflüchteten aus arabischsprachigen Gesellschaften sind religiöse und Kontaminationsideen die häufigste Art von Zwangsgedanken. Dieser Umstand macht die Diagnosestellung von OCD umso schwieriger, da mit diesen Inhalten Scham- und Schuldgefühle assoziiert sind, die die Zeit bis zur aktiven Suche nach Hilfe deutlich verzögern können. Die Anwendung kultursensibler diagnostischer Instrumente ist wichtig, um Zwangssymptome bei Geflüchteten korrekt und frühzeitig diagnostizieren zu können. Wir schlagen daher vor, die arabische Version des Zohar-Fineberg Obsessive Compulsion Screens (ZF-OCS) um die zuverlässige und explizite Erfassung von religiösen und Kontaminationsgedanken zu erweitern.

Abstract
Vocabulary plays a crucial role in foreign language learning, and vocabulary mastery proves to be challenging at
different competence levels. Compared to other areas of research into Chinese as a foreign language, vocabulary acquisition and
vocabulary teaching have rarely been investigated. The aim of this study is to investigate the relationship between vocabulary
learning strategies and vocabulary size and to verify whether vocabulary size is positively correlated to proficiency level. A
total of 95 Italian undergraduate Chinese learners, from elementary to intermediate levels, participated in this study. The
participants were first given a vocabulary learning questionnaire and then a vocabulary size test. Statistical and qualitative
analyses of the data revealed two trends: a poor variety of vocabulary learning strategies and a positive correlation between
vocabulary size and proficiency level.

Abstract
The All Party Parliamentary Group on Refugees occupies a position outside the official legislative system of the
United Kingdom, but inside a lobbying network. This gives it a unique place in terms of communicating on behalf of refugees and
refugee causes. The Group’s Twitter feed shows that its language is different to that of campaigning organisations outside
Parliament and is constrained by procedure, parliamentary practice and the political reality of a party-based environment. Aimed
at Parliamentarians, the feed is used to support and promote causes and specific policy proposals. It plays a role in reporting
what is going on in Parliament and supports and builds alliances with other organisations inside and outside the system. The
feed’s content follows the primary information-providing objective. It could however make that information of more use to
recipients, by changing the way in which some of that information is presented.

Abstract
The effect of applied strain on the luminosity and divergence of neutron monochromator with fully asymmetric diffraction geometry will be reported. The monochromator used silicon single crystal with 200 x 30 x 4 mm3, which has the parallel face of the crystal to the planes (220). The plain used for this monochromator was (311), which has a 31.5 degree to the (220) face. Fully asymmetric diffraction geometry had been fulfilled with the take-of-angle of the monochromator at 63 degrees. Four lines are bending system used for applying the strain to the crystal, which remote-controlled by computer. The 0, 25, 50, 75, 100, 125, 150, 175, 200 microStrain (uStrain) applied the monochromator crystal respectively. Diffracted neutron from the monochromator was monitored by using a neutron camera for evaluating the luminosity and divergence of the beam. The wavelength of the monochromatized beam was calibrated by using a Nickel rod.

Authors: Sugiharto S 
Published: February 2020

Abstract
A simple radiotracer experiment has been carried out to simulate water flow in a conduit made of PVC plastic with a diameter of 2 in. (50.8 mm). The water was supplied from a water tank with a volume of 500 liters During the experiment flow rate of water in the conduit was maintained constant at a speed of 0.2 m.s−1 by adjusting valve at the farthest end of the conduit. Br-82 isotope solution in a concentration of 1 mCi.ml−1 was injected instantaneously into the conduit. Injected isotope follows the bulk flow of water in the conduit. A scintillation NaI(Tl) radiation detector which was placed on the conduit at a distance of 8 m from injection point captures the radiation energy of injected radiotracer when passing it and generate residence time distribution (RTD) curve which represent isotope particle spent in the conduit. To get meaningful information, a mathematical simulation so-called the axial dispersion model has been developed to evaluate the RTD curve with Peclet number, Pe, as a model parameter. The best fitting of the RTD curve model onto the experimental one was achieved when the Pe is equal to 13. The calculated fitting error was 0.003, very extremely low as expected. This result indicated that the axial dispersion model was able to quantify water flow and simulated Peclet number indicated that convection flow is more dominant compared to the radial flow.

Published: February 2020

Abstract
The development of the rice cultivation area is needed to increase rice productivity through expanding of marginal land especially in high-elevation areas of Indonesia. Temperature, solar radiation and rainfall influence rice yield by directly affecting the physiological processes involved in grain production. The effects of abiotic stress on grain yield and yield components vary with the growth stage, depending on variety and weather conditions. The major conlinet of rice cultivation in high elevation areas is the lack of cold tolerance varieties. The objective of this research was to obtain the information on the stability of rice genotypes to be adapted in highland across three different high-elevations (700, 900 and 1200 m above sea level). The rice genotypes derived from mutation induction and hybridization treatment were cultivated in the dry season and rainy season. The AMMI analysis revealed KN-10-111, KN-20-124 and RB-10-98 mutant lines were the most stable genotypes across environments evaluated. KK-10-249 mutant line was specific in 900 m above sea level area, C4-30-21, RB-10-95 and KN-20-127 mutant lines adapted in 700 m above sea level area (dry season) whereas B-30-82, IPB117-F-20 and C3-10-171 lines specified in the rainy season. PK-20-133 mutant line had stability in 1200 m above sea level area (rainy season) while OS-30-199 and Sarinah genotypes more stable in the dry season with low temperatures stress conditions. The stable and promising mutant lines could be released and developed a new variety to improve the yield of rice highland adapted.

AbstractThe study was aimed to examine the deoxyribonucleic acid (DNA) damage level between medical and non-medical radiation workers using the comet assay method. The radiation-exposed group (29 subjects) and the control group (29 subjects) were chosen from the administration staff. The assessment of single-strand DNA damage hosted by peripheral blood lymphocyte was performed using the alkaline comet assay, the tail length and long-tailed DNA were measured to detect the DNA damage. An independent sample t-test was used to assess the statistical difference between groups. The results showed that comet tail length mean measured in the exposed worker’s group was 25.57±4.4 μm whereas the mean percentage of long-tailed DNA was 6.97±1.53. In the control group, the mean tail length was 23.15±7.57 μm and the long-tailed nucleus percentage was 5.65±1.99. Mean values for the tail length measured were no significantly higher in the exposed group compared to the control group (P=0.15), whereas the percentage of long-tailed nuclei was significantly higher in the exposed group compared to the control group (P=0.007) . The observed single-strand DNA can be measured by using the alkaline comet assay. The DNA damage can be influenced by radiation exposure in medical radiation workers.

Abstract
An experimental 10 MWt power reactor based on high-temperature gas-cooled reactor technology has been planned for Indonesia. The concept was initiated at the end of 2014, and the basic engineering design was completed in 2017. Currently, the development program is focused on detailed engineering design. The type of fuel aimed in the design is a pebble-bed type that contains fuel kernels made of uranium dioxide (UO2) coated in four layers of three isotropic materials. Those layers are a porous buffer layer made of carbon, usually followed by a dense inner layer of pyrolytic carbon (PyC), followed by a ceramic layer of silicon carbide (SiC) to retain fission products, and after that by a dense outer layer of PyC. One of the issues of the fuel system is the problem of corrosion caused by the interaction of fission products such as silver (Ag) and palladium (Pd) with the SiC layer. One of the candidates to resolve the issue is to replace SiC with zirconium carbide (ZrC) which is more resistant to corrosion at high temperatures. In this study, we investigate the effects of the replacement on the neutronic properties of the reactor design at different operating temperatures. For the purpose, we use the SRAC (Standard Reactor Analysis Code) system to calculate the energy spectrum and multiplication factors of the advanced TRISO fuel design. The result of the investigation showed that, in terms of the Doppler coefficient of reactivity, the use of ZrC seems to act more favorably than that of SiC. However, ZrC increases the parasitic neutron capture in the fuel system resulting in lower initial core reactivity which was also confirmed by a slight hardening of the neutron spectrum.

Abstract
The utilization of cornstalk as a raw material for bioethanol production is an alternative solution to increase the added value of lignocellulose from agricultural wastes. The glucose content of lignocellulose material can be increased through the hydrolysis process by cellulolytic microorganisms. This research aims to obtain fungi Trichoderma reesei which capable of optimizing glucose content on lignocellulose materials and influence to increase in bioethanol production by Saccharomyces cerevisiae. The experiments were conducted with 2 factorials consist of substrates pre-treatments and hydrolysis. Pre-treatment of substrates by aqua dest (S1), 1% H2SO4 (S2) and 1% NaOH (S3) solution. Treatments of hydrolysis consist of control (K) and fungi T.reesei 750 Gray (H). The fungi T.reesei 750 Gray was obtained from optimizing by gamma rays at a dose of 250, 500, 750 and 1000 Gray. The fungi T. reesei 750 Gy have the specific cellulase activity about 0.24 U/mg higher than the fungi T. reesei 0 Gy about 0.16 U/mg. Pre-treatment of substrates with 1% NaOH (1: 5 w/v) solution and hydrolysis by fungi T.reesei 750 Gray (S3H) is suitable for solid fermentation with S.cerevisiae. After 2 days of solid fermentation by Saccharomyces cerevisiae, the bioethanol contents in S3H medium about 387 ppm while S1K (control) about 196 ppm or increase about 98% (ppm/ppm). This result is expected to be an alternative solution for the utilization of cornstalk for bioethanol production.

Abstract
The development of radiation utilization, in medical application, increases every year. One of them was the interventional radiology facility. Interventional radiology has been chosen to replace invasive procedures for diagnosing and cure several cases of the blood system. However large radiation exposure for radiation workers remains the main potential of an occupational hazard. Therefore, radiation protection plays an important role in ensuring the occupational dose does not exceed the regulated limits by BAPETEN. The purpose of this study was to determine the estimated effective dose (mSv) received by radiation workers undergoing interventional procedures. Occupational doses were measured using the thermoluminescence dosimeter (TLD) chips which placed on critical organ areas such as thyroid, thorax and gonads / ovaries during interventional procedures. In this study, the interventional procedures carried out for PCI, embolization, PTCA, limb intervention, thoracic intervention and cerebral intervention. The TLD was then read using the TLD Reader 3500 Harshaw. The results of this study showed mean effective dose received by doctors, nurses and radiographers in several hospitals in Indonesia due to carrying out interventional procedures was 0.043 ± 0.034, 0.048 ± 0.064 and 0.047 ± 0.031, respectively. The dose received by the radiation worker is still below the limit regulated by BAPETEN, which is 20 mSv / year. These doses were varied based on the type of interventional procedure and the time of fluoroscopy.

Abstract
The use of radiopharmaceuticals for cancer diagnosis and therapy is increasing. The radiopharmaceutical is also used to monitor the progress of a disease and determine the appropriate treatment. However, the use of radiopharmaceuticals needs to pay attention to the alteration in pharmacokinetics, pharmacology, and toxicity that are influenced by the drugs consumed by patients. Interaction between drugs with radiopharmaceuticals will cause alteration in pharmacokinetic effects. Therefore, this study aimed to determine the pharmacokinetic interaction of “-Tc-Glutathione radiopharmaceuticals with doxorubicin cancer drug in mice (Mus musculus). The pharmacokinetic studies were performed using four groups of animal model and each group consists of three rats. The groups were classified to normal mice without treatment of doxorubicin as normal mice control (I), normal mice treated with doxorubicin (II), cancer model mice without treatment of doxorubicin as cancer model mice control (III), and cancer model mice treated with doxorubicin (IV). The radioactivity in blood at a certain interval was then calculated to determine the distribution and elimination half-time. The distribution halftime of group I, II, III, and IV were 0.004±0.001, 0.0037±0.0001, 0.003±0.0001, and 0.0037±0.0001 hours, respectively, while the elimination half-time were 5.310±1.050, 10.7344±0.4692, 72.712±2.427, and 26.9320±7.8152 hours, respectively. The results of the T-test showed that there was a significant difference in elimination half-life of 99mTc-Glutathione between the treated group and the control group. These results indicate that administration of the doxorubicin before administration of 99m-Tc-Glutathione needs to be avoided because it can alter the elimination half-life of »-Tc-Glutathione. The results of this study are expected to provide benefits for clinicians in nuclear medicine to avoid the interpretation of incorrect diagnosis results, to achieve high-quality health service and will have a positive impact on the appropriate treatment for patients.

Abstract
Kartini research reactor which is located at Yogyakarta Indonesia is intended for research, education and training. Students from universities around the city use the reactor for experiments regularly. Regarding the plan of building the first nuclear power plant in Indonesia, the reactor could be improved as the facility of a nuclear power simulator for personnel training of a nuclear power plant. Some improvements on instrumentation and control system were conducted to support the purpose, such as developments of data acquisition of reactor operation parameters, and internet reactor laboratory for remote experiment through the internet connection. However, a power control system for the automatic operation of the reactor is not developed yet. It is important to design an automatic power control for the improvement of the reactor as a simulator of a light-water nuclear power plant. This paper discusses the design of power control of the Kartini reactor based on the Kartini reactor accident and transient code. The control model refers to that of a light water-cooled nuclear power plant. Calculation results show that the control model is applicable to the Kartini reactor. The criterion of SCRAM actuation of the Kartini reactor is satisfied by a small value (0.1) of a control parameter of b. In the future, the control rod simulator which is available in the Kartini reactor might be used to simulate the control system before it is realized to the real reactor.
