Authors: Nguyen Van Dung
Published: September 2021

In Vietnam mining industry is significantly contributing to the socio-economic development. For the industrialization, many kinds of minerals are being exploited and processed that caused the Earth surface to be disconcerted leading to the increase of erosion of soil that possibly carries radioactive nuclides of the natural radioactive chains. Mining could cause increasing radioactive background to the miners as well as to the public members around the mines. This paper presents radiological parameters associated with mining and processing ilmenite minerals in coastal sand for titanium for export in Binh Dinh province, Central Part of Vietnam.

Published: September 2021

The present work aims to perform burnup calculation of the OECD VVER-1000 LEU (low enriched uranium) computational benchmark assembly using the Monte Carlo code MCNP6 and the deterministic code SRAC2006. The new depletion capability of MCNP6 was applied in the burnup calculation of the VVER-1000 LEU benchmark assembly. The OTF (on-the-fly) methodology of MCNP6, which involves high precision fitting of Doppler broadened cross sections over a wide temperature range, was utilized to handle temperature variation for heavy isotopes. The collision probability method based PIJ module of SRAC2006 was also used in this burnup calculation. The reactivity of the fuel assembly, the isotopic concentrations and the shielding effect due to the presence of the gadolinium isotopes were determined with burnup using MCNP6 and SRAC2006 in comparison with the available published benchmark data. This study is therefore expected to reveal the capabilities of MCNP6 and SRAC2006 in burnup calculation of VVER-1000 fuel assemblies.

Authors: Luong Thi Hong , Nguyen Tien Phong , Pham Thi Bich , Nguyen Du Huyen
Published: September 2021

This paper presents the design and validation of a neutron survey meter. The meter consists of a PRESCILA neutron probe (with good sensitivity, directional response, gamma rejection, and enhanced high-energy response to 20 MeV) and an electrometer developed at Non-Destructive Evaluation center. The homogeneity response of the PRESCILA neutron probe was investigated as a function of distances from the 241Am - 9Be source in order to obtain the appropriate distance for accurate count-rate measurements using the neutron survey meter. A system consists of the PRESCILA neutron probe and the Ludlum Model 2326 electrometer was then used for measuring neutron ambient dose equivalent rates in the range from 50 cm to 200 cm with the step of 25 cm. The relationship between the count-rates and neutron dose equivalent rates (in the distance ranged from 50 to 200 cm) were deduced to validate the proper operation of the neutron survey meter.
Study on the removal of interferences for the determination of ⁸⁷Sr/⁸⁶Sr isotopic ratio in petroleum drill-hole water samples using isotope dilution – inductively coupled plasma mass spectrometry (ID – ICP-MS)
Authors: Nguyen Thi Kim Dung , Thai Thi Thu Thuy
Published: September 2021

87Sr/86Sr isotopic ratio is one of the useful tools that can authenticate the original source of the natural products from the earth-created and/or geological processes. However, the effect of interferences in petroleum drill-holes water sample such as thickness of sample matrix or isotopic signal of 87Rb might cause the low precision of 87Sr/86Sr determination using quadrupole inductively coupled plasma spectrometry (ICP-MS). The elimination of these mentioned effects was thus studied by using the ion - exchange chromatography. Calcium in sample matrix was separated on anionite column (Bio-Rad AG1-X8 resin) in methanol medium with the high efficiency while rubidium was removed from strontium on cation exchange resin (Bio-Rad AG50-X8) with strontium recovery over 99%. The isotope dilution technique with 86Sr - enriched isotopic standard solution was used for the control of separation process. The 87Sr/86Sr isotopic ratio was thus determined using ICP-MS with the signal correction by a strontium isotopic ratio standard reference material (NIST SRM 987).

Published: September 2021

The paper investigates various computational modelling issues associated with VVER-440 fuel depletion, relevant to burnup credit. The SCALE system and the TRITON sequence are used for the calculations. The effects of variations in depletion parameters and used calculation methods on the isotopic vectors are investigated. The burnup behaviour of Gadolinium is quite important in actual core analysis, but its behaviour is somewhat complicated, requiring special treatment in numerical modelling and calculations. Therefore, a special part of the paper is devoted to the treatment of Gadolinium-bearing fuels. Moreover, some discussions on power normalization are also included. To assess the acquired modelling experience used to predict the VVER-440 spent fuel nuclide composition, the measured compositions of Novovoronezh NPP irradiated fuel assembly are compared to data calculated by TRITON sequence. The samples of fuel assembly with 3.6 wt. % U-235 enrichment underwent 4-cycle campaign of totally 1109 effective full power days in the core and cooling period of 1-13 years. Calculated concentrations are compared to measured values burdened with their experimental uncertainties for totally 47 nuclides. The calculated results show overall a good agreement for all nuclides, differences from measured are pointed out and discussed in the paper.
Processing of the multigroup cross-sections for MCNP calculations
Authors: Lüley Jakub , Vrban Branislav , Čerba Štefan , Osuský Filip , Nečas Vladimír
Published: September 2021

Stochastic Monte Carlo (MC) neutron transport codes are widely used in various reactorphysics applications, traditionally related to criticality safety analyses, radiation shielding and validation of deterministic transport codes. The main advantage of Monte Carlo codes lies in their ability to model complex and detail geometries without the need of simplifications. Currently, one of the most accurate and developed stochastic MC code for particle transport simulation is MCNP. To achieve the best real world approximations, continuous-energy (CE) cross-section (XS) libraries are often used. These CE libraries consider the rapid changes of XS in the resonance energy range; however, computing-intensive simulations must be performed to utilize this feature. To broaden ourcomputation abilities for industrial application and partially to allow the comparison withdeterministic codes, the CE cross section library of the MCNP code is replaced by the multigroup (MG) cross-section data. This paper is devoted to the cross-section processing scheme involving modified versions of TRANSX and CRSRD codes. Following this approach, the same data may be used in deterministic and stochastic codes. Moreover, using formerly developed and upgraded crosssection processing scheme, new MG libraries may be tailored to the user specific applications. For demonstration of the proposed cross-section processing scheme, the VVER-440 benchmark devoted to fuel assembly and pip-by-pin power distribution was selected. The obtained results are compared with continues energy MCNP calculation and multigroup KENO-VI calculation.

Published: September 2021

This paper presents the conceptual design of a 300 MWt small modular reactor (SMR)using fuel assemblies of the AP1000 reactor. Numerical calculations have been performed to evaluate a proper active core size and core loading pattern using the SRAC code system and the JENDL-4.0 data library. The analysis showed that Doppler, moderator temperature, void, and power reactivity coefficients are all negative over the core lifetime. Semi-analytical thermal hydraulics analysis reveals acceptable radial and axial fuel element temperature profiles with significant safety margin of fuel andclad surface temperature. The minimum departure from nucleate boiling ratio (MDNBR) is also calculated. The results indicate that a cycle length of 2.22 years is achievable while satisfying the operation and safety-related design criteria with sufficient margins.

Published: September 2021

The treatment of electron beam was tested for gaseous pollutants of volatile organiccompounds (VOCs), dioxin, and inorganic oxides (NOX and SOX). The representative VOCs of xylene and toluene were oxidized completely with electron beams using prototype hybrid system equipped with electron accelerator and MnO2 catalysts. More than 90% of dioxin in municipal solid waste incinerator gases was decomposed at a dose of 14 kGy. Nitrogen oxides and sulfur oxides in coal-fired flue gases were recovered as a fertilizer by the addition of NH3 under electron-beam irradiation.Electron beam is expected to be a promising method for treating gaseous pollutants.

Gamma-delayed spectroscopy measurements of 67Fe have been performed at RIKEN,Japan. The spectra from (p, 2p) and (p, pn) channels show a sharp peak at 367 keV. While the total isomer-yield spectrum presents clearly 2 peaks at 367 and 387 keV. The ratio of these two gammas’ intensity was determined to be equal to 0.126(3), in agreement with previous experiments. The origin of these two gammas could be from different isomers of 67Fe. The half-life (T1/2) of the isomer which decays to the 367 keV level was determined to be equal to 150(10) s, more than twice as long as from previous experiments.

Authors: Nguyen Van Thai , Doan Manh Long , Tran Chi Thanh
Published: September 2021

A severe accident-induced of a Steam Generator (SG) tube releases radioactivity from the Reactor Coolant System (RCS) into the SG secondary coolant system from where it may escape to the environment through the pressure relief valves and an environmental release in this manner is called “Containment Bypass”. This study aims to evaluate the potential for “Containment Bypass” in VVER/V320 reactor during extended Station Blackout (SBO) scenarios that challenge the tubes by primarily involving a natural circulation of superheated steam inside the piping loop and then induce creep rupture tube failure. Assessments are made of SCDAP/RELAP5 code capabilities for predicting the plant behavior during an SBO event and estimates are made of the uncertainties associated with the SCDAP/RELAP5 predictions for key fluid and components condition and for the SG tube failure margins.

Authors: Cole Amanda
Published: September 2021

Portuguese art song is an underexplored niche in the song recital repertoire. One factor that makes it difficult for singers to make sense of it is the limited information on Portuguese culture. In this discussion of the music of Fragoso and the texts of António Correia de Oliveira in relation to the cycle Canções do Sol Poente (Songs of the Setting Sun), the author provides cultural and historical information with particular reference to the Portuguese concept of saudade, with discussion on how saudade is intertwined with the movements of nationalism, neoromanticism, and saudadismo of the 1890s that led to the Portuguese revolution in 1911 and the subsequent blossoming of creative arts in the nation.

Spiritual Quotient (SQ), which is the foundation needed to function Intelligent Quotient (IQ) and Emotional Quotient (EQ) effectively. Even SQ is the highest intelligence. So that humans who have high SQ are a category of people who have noble morals. So Islamic education will play a role in aspects of humanity which can actually be maximized through SQ sensitivity. This study is intended to answer the following problems: (1) What is the General Concept of Spiritual Quotient? (2) What is the Concept of Spiritual Quotient in the Perspective of Islamic Education? These problems are discussed through library data collection, reading, taking notes, and processing research materials. This scientific work is a type of library research research, which is a series of activities related to the methods of collecting library data, reading, taking notes, and processing research materials which are library research or pure research. All data were analyzed using a philosophical approach. This study shows that: (1) Spiritual intelligence (SQ) means the ability to know and understand ourselves fully as spiritual beings and as part of the universe. Having spiritual intelligence means that we fully understand the meaning and essence of the life we live and where humans are going. Based on these two concepts, it shows that Western SQ is more oriented towards the completion and achievement of world happiness, while Islamic SQ is more about achieving happiness in the world and the hereafter. If both are used ideally, SQ can be implemented in order to achieve "happiness" both in this world and in the hereafter. (2) The concept of Spiritual Quotient in the perspective of Islamic education is spirituality education that can sharpen the quality of spiritual intelligence, namely the values of spirituality itself which are aimed at education

Introduction: The aim of this study was to investigate the relationship between nasal mucociliary clearance time (NMCT), degree of smoking dependence, cumulative smoking burden and OSAS severity in smokers. Material and methods: 123 patients (Group 1) with OSAS and 92 healthy controls (Group 2) were included in the study. Group 1 was divided into smokers (Group 1a) and non-smokers (Group 1b). In Group 1a, cumulative smoking burden and Fagerström nicotine dependence test (FNDT) were questioned. Saccharin test was applied to Groups 1 and 2. Student-t, Mann-Whitney-U, Anova, Kruskal-Wallis tests were used to compare the means. Results: NMCT was higher in Group 1 than Group 2 (p = 0.005). The duration of NMCT was higher in Group 1A than Group 1B (p = 0.002). In Group 1a, NMCT values of mild and moderate OSAS patients were longer than in Group 1b (p = 0.02, p = 0.01, respectively). NMCT values of patients with mild dependence were shorter than those with moderate or severe dependence (p = 0.032, p < 0.001, respectively). Conclusion: Mucociliary clearance time was higher in smokers with OSAS than non-smokers. While OSAS has a negative effect on mucociliary clearance, smoking also exacerbates the condition.

The two-parameter Weibull distribution is highly efficient in modeling wind speed characteristics. In this study, the wind speed data of 32 cities in three different regions of Turkey have been comparatively analysed to estimate Weibull distribution function parameters by the use of three well-known methods (Graphical Method (GM), Maximum Likelihood Method (MLM), Justus Moment Method (JMM)) and three new parameter estimation methods (Energy Pattern Factor Method (EPFM), Wind Energy Intensification Method (WEIM), Power Density Method (PD)) which have been proposed in recent years. Three years of hourly wind speed data of the specified regions have been used. The performance metrics of these analyses have been compared using Wind Energy Error (WEE), Root Mean Square Error (RMSE), and Coefficient of Determination (R2). The results have shown that while the PD method has high model performance, the JMM is closely competitive with the MLM. Besides, the wind energy densities that were estimated by using actual data have been compared with the resulting Weibull distribution. It has been clear that the method that has the closest estimation to the actual values is the PD method.

The commercially available IC LT1228 is an interesting active device due to its advantage features, such as a fast transconductance amplifier, a wide bandwidth over a wide range of voltage gain, low total harmonic distortion (THD), high impedance differential input, etc. The single-input triple-output (SITO) voltage-mode (VM) multifunction biquadratic filters using ICs, LT1228s are introduced in this research. This circuit design provides the three-filtering functions, low-pass (LP), high-pass (HP), and band-pass (BP), without changing the circuit architecture. It comprises three LT1228s, four resistors, and two capacitors connected to the ground. The low impedance voltage output nodes are HP and BP responses. The quality factor (Q) and the pole frequency (ω0) can be electronically and orthogonally tuned by altering the third LT1228’s bias current (IB). The PSPICE simulation and the experiment are verified to describe the circuit operation.

This paper presents the trajectory tracking control of a two-link planar robot manipulator using MSC Adams and MATLAB co-simulation which enables the innovative virtual prototyping of the systems without any mathematical expressions. Firstly, the tracking control performance of the planar manipulator is investigated using the Sliding Mode Control (SMC) controller and the Proportional Integral Derivative (PID) controller in terms of the performance analysis. As a result, the SMC demonstrates effective control performances compared to the PID controller according to the required trajectory, settling time, and end position of the system. Then, the SMC controller parameters are determined using the different optimization methods offered as open source by MATLAB/Response Optimization Toolbox and compared to each other. In the virtual co-simulation, the trajectory tracking control performance is observed to be improved by optimizing the parameters of the SMC controller using Simplex Search (SS) method. All control results are examined and presented with graphics and international error standards.

Image retargeting is a manipulation approach for resizing the images while aiming to keep the image distortion at a low level. Detecting image retargeting is of importance in image forensics or sometimes of importance in checking the originality. The aim of this paper is to introduce a new blind detection method for identifying retargeted images based on seam carving. For this purpose, a new method based on stripes at various numbers, Local Binary Pattern (LBP) transform, and energy map is introduced. The sub-images were obtained from square root of the energy map of LBP transform in the form of stripes for the feature extraction and these were evaluated in terms of several statistical features. The features extracted both from the natural and the seam carved images were used to train a Support Vector Machine (SVM) as a binary classifier. Experimental results were obtained using four-fold cross validation to improve the validity of the results during the evaluation process. According to the experiments, the proposed method produces improved accuracies when compared with the state-of-the-art solutions for the image retargeting detection based on seam carving.

Background: Cytomegalovirus (CMV) is one of the leading viral agents that can pave the way for serious complications and organ damage in solid organ transplant (SOT) recipients after transplantation. Strategies have been developed to protect at-risk patients from CMV infection following transplantation. Since more than 90% of adults in Turkey were positive for CMV IgG, universal CMV prophylaxis was applied, and the results were evaluated. Objectives: This study aimed to evaluate the results of universal CMV prophylaxis after liver transplantation in the long term. Methods: A total of 1,090 liver transplant patients were evaluated in terms of CMV infection in the Organ Transplantation Institute of Inonu University, Malatya, Turkey, from October 2014 to December 2019. In order to identify the CMV infections, quantitative nucleic acid amplification (QNAT) was used to detect potential CMV DNA. The cut-off value of CMV DNA was determined to be 1000 copies/mL after transplantation. Results: According to the clinical and laboratory assessments, 33 (3%) patients were diagnosed with CMV infection, and 25 (2.3%) patients were evaluated as possibly having CMV syndrome. Also, eight of the 33 patients were assessed as having end-organ CMV disease and 25 as probable CMV syndrome. In the late period following prophylaxis, CMV infection was observed in 10 (0.9%) cases. The infection rate after prophylaxis (0.9%) was lower than the infection rate (2.1%) seen during prophylaxis. Conclusions: Close clinical follow-up with CMV prophylaxis and strict monitoring of CMV DNA by determining a specific cut-off point are important in the follow-up of liver transplant patients.
Is Aberrometric Analysis Based on Zernike Modes That May Not Be Correct?
Authors: Sadeghi Mehrdad , Omidian Jalil
Published: September 2021

Context: Aberrometric analysis of the wavefront in patients with refractive disorders is performed using the Zernike pyramid mode and based on that, a treatment plan is determined however, it is not clear what Zernike modes are derived from mathematical analysis, exactly how much they correspond to the clinical facts this article discusses ways to study this issue. Evidence Acquisition: One of the methods for studying optical systems is the aberrometry of wavefront. the wavefront is a two-dimensional surface perpendicular to a bunch of parallel light rays, that all these rays have the same phase on this surface (because light emits sinusoidally and therefore has multiple identical phases) whenever these rays pass through a refractive surface, it is also called the reference level this refractive index will be ideal if the homogeneity of these rays is maintained and the rays of this bunch of light will be able to focus at one point, but if the by passing light through the refractive surface the wavefront will be disturbed and the lights on this surface have different phases than the reference surface then it is said there is a discrepancy or deviation between the reference surface and the wavefront. Therefore, aberration is the creation of the distance of the wavefront in a certain phase from the refractive surface or reference surface. When we say refractive surface, we do not mean a specific place like the cornea because other than the cornea other factors such as crystalline lens, vitreous, retin even tear layer they are involved in creating aberrations, but usually the pupil range is considered as the reference surface. Results: Modes z-13 and z13 of the fourth order and modes z04 and z-24, z24 from the fifth order and modes z-15, z15 of six order and modes z06, z-26, z26 of seventh order they are not pure and mathematically they have some lower order which may cause in analysis aberrometry disruption as a result, the relevant orders have a little more or less value. Conclusions: There are no strong clinical reasons for Zernike modes to be a fully accurate description of aberromerty, so clinicians should consider other clinical data and findings in their interpretation. Some modes of high-order Zernike have sentences of low-order This can cause abnormal analysis.

Background: Fast, reliable, and cost-effective tests are recommended for tuberculosis diagnosis and drug susceptibility testing, especially in resource-limited settings. Objectives: This study aimed to evaluate the performance of thin-layer agar for tuberculosis diagnosis and drug susceptibility testing. Methods: Samples were collected from patients with presumptive tuberculosis and tested using thin-layer agar for tuberculosis and drug susceptibility testing in parallel with Lowenstein Jensen culture method for tuberculosis diagnosis and proportion method for drug susceptibility testing as the gold standard. Receiver operating characteristic curve analysis was performed to calculate the performance parameters. Results: Thin-layer agar method showed sensitivity and specificity values of 96.63% and 62.50%, respectively, for the isolation of Mycobacterium tuberculosis directly from specimens. Drug susceptibility results using thin-layer agar showed sensitivity values for isoniazid, rifampicin), ethambutol and streptomycin were 94.74%, 86.84%, 94.74% and 81.58%, respectively, while the specificity values were 100%, 100%, 86.27% and 100% for isoniazid, rifampicin, ethambutol and streptomycin, respectively. Results were available in a median time of 16 days for thin-layer agar and 25 days for the conventional method. Conclusions: The thin-layer agar method is a relatively rapid, simple, and cost-effective method for the diagnosis and drug susceptibility testing of M. tuberculosis. It may be a useful tool for establishing tuberculosis laboratories in resource-limited settings because it does not require expensive equipment and a high level of training. Our study may help in choosing the appropriate treatment and control of tuberculosis.

The new programming period 2021 – 2017 brings a new philosophy of integration - in the emergence of integrated territorial strategies (ITS) and their financing through integrated territorial investments (ITI). The aim of the paper is, based on the above reasons, to evaluate the project activities of the microregion Termál considering the implemented projects in the programming periods 2007 – 2013 and 2014 – 2020 (ex-post evaluation) as well as the readiness of the area for financial resources in the programming period 2021 – 2027 (ex-ante evaluation). In terms of methodology, we used the comparative analysis of various information sources (mainly Programs of economic development and social development of municipalities, microregion Termál and databases of the Department of Strategic Activities of the Municipality of Nitra Region) and standard statistical and cartographic methods leading to data processing and visualization. The results provide information on the diversification of obtained and expected funds at individual municipalities and the whole territory. While in both previous programming periods, the focus was mainly on building social and technical infrastructure. At the beginning of the new programming period, expectations mainly focused on increasing territorial competitiveness by supporting industries using local resources and sustainable smart energy communities.
