Not enough traction: Barriers that aspiring researchers from low- and middle-income countries face in global health research
Authors: Shumba Constance S. , Lusambili Adelaide M
Published: September 2021

There is a growing concern of low representation of researchers from low-middle-income countries (LMICs) in the publication of global health research in high-impact peer-reviewed journals. Nobody denies that researchers from the developing world generally face several obstacles to publishing their research. In this viewpoint, we share some of the barriers we have observed from our experience working in both academia and global health practice in low and middle-income countries such as limited opportunities for research funding, gender disparities, and language barriers. Beyond presenting the barriers, we also provide some pragmatic solutions to addressing these barriers through increased research financing, capacity building, gender equity and inclusion, and editorial support. Most importantly, we call for setting a new level of ambition in redressing the imbalances and actualizing the leadership and emergence of a veritable critical mass of LMICs researchers.
Dollar value of disability-adjusted life years in South Africa in 2019
Authors: Senkubuge Flavia , Hongoro Charles , Muthuri Kirigia Joses
Published: September 2021

Background

To date, no study has estimated the dollar value of DALYs lost from a wide range of diseases and conditions in South Africa. The specific objectives of this study were: (a) to estimate the dollar value of disability-adjusted life-years (DALYs) lost in South Africa in 2019, and (b) to forecast the reductions in the dollar value of DALY losses assuming the United Nations Sustainable Development Goal 3 (SDG3) five disease-specific targets are attained by 2030.

Methods

The study employs the human capital approach to convert the DALYs lost from all causes into their International Dollar (Int$) equivalents. The DALYs data used in the analysis was from the Institute for Health Metrics and Evaluation (IHME) Database, per capita GDP data from the International Monetary Fund (IMF) Database, and current health expenditure per person from the Global Health Expenditure Database of the World Health Organization (WHO).

Results

South Africa lost 26.6 million DALYs in 2019 with a total value of Int$ 313.5 billion and an average value of Int$ 11,791.6 per DALY. Approximately Int$ 155.6 billion (50%) was attributed to communicable, maternal, neonatal, and nutritional diseases (CMNND); Int$ 120.4 billion (38%) to non-communicable diseases (NCD); and Int$ 37.4 billion (12%) to injuries (INJ). The health conditions related to SDG3 targets 3.1 (maternal mortality), 3.2 (neonatal mortality), 3.3 (CMNND), 3.4 (NCD) and 3.6 (INJ) resulted in DALY losses with a value of 256.4 billion, i.e. 82% of the total monetary value of DALYs lost in 2019. Therefore, achieving the five SDG targets would potentially save South Africa Int$ 139.7 billion per year.

Conclusions

Health development policy-makers should employ this type of evidence when making a case for increased investments into the national health-related systems to bridge the extant gap in the universal health service coverage index for South Africa.

Published: September 2021

The study investigated the Profitability Analysis of selected vegetable farmers in Yenagoa Local Government Area, Bayelsa State. Multi stage sampling techniques was adopted. First stage involves a simple random selection of 13 communities from the 20 communities present in YELGA. The second stage involves the selection of five (5) vegetable (bitter leaf) farmers each from the selected communities summing up to One hundred (100) farmers (bitter leaf). Sixty-nine (69) questionnaires were retrieved out of one hundred (100) copies and used for the analysis. The result indicates that 58.0% of the respondents fall between ages ranged of 20-39. Majority of the vegetable farmers were married (44.9%), females (69.1%) dominated vegetable production in the study area, 50.7% had family size of 1-4 people in their households, 82.6% had one form of education or the other. Total Fixed Cost (TFC) was ₦820,000.00 while Total Variable Cost (TVC) was ₦270,500.00 with Net Farm Income (NFI) of ₦377,800.00 during production period. Return on investment was ₦0.35 which implies profitability of vegetable production in the study area. The study identified inadequate storage facilities, lack of organized market, inadequate planting materials, inadequate finance, high cost of transportation, lack of land, high spread of pest and disease, high cost of labor, inadequate water supply and lack of modern technologies as the major problems of vegetable farmers in the study area. It was therefore recommended that Government should provide vegetable farmers with storage facilities organized market structure in order to encourage them increase their scale of production.

Authors: Pham Thi Thu Hong , Nguyen Thanh Duoc , Nguyen Thi Ly , Chu Nhut Khanh , Cao Van Chung , Doan Binh , Nguyen Tuan Kien
Published: September 2021

Vietnamese graphite powder was irradiated by electron beam radiation (EB) at a range of dose from 0 to 120 kGy, then the graphite samples were expanded with a mixture of H2O2:H2SO4 (1,4:20, v/v) incorporating microwave treatment at 700 W for 30 seconds. The characteristic properties of graphite before and after expansion were evaluated by methods of FTIR, Raman, SEM and XRD. Besides the self-assembled of the graphite’s structure after irradiation, the electron beam radiation also facilitated intercalation processing to make expanded graphite, with coefficient of expansion (Kv) 35% higher than that of pristine graphite.

Published: September 2021

Oligochitosan (COS) was prepared by gamma Co-60 irradiation of chitosan/H2O2 solutions and mixed with cornstarch to form the powder with content of 100 000 mg COS/kg. The striped catfish (P. hypophthalmus) was fed with diets containing 100 mg COS/kg feed for 9 months at pond culture. The effects of COS supplementation on growth performance, feed conversion ratio (FCR) and survival rate in striped catfish were investigated. The results indicated that the growth performance and survival rate of striped catfish fed with 100 mg COS/kg were significantly improved and the FCR decreased. The average weight gain, survival rate and FCR of striped catfish fed with diets containing COS were 971 ± 85 gram, 83.19 ± 0.35 % and 1.477 ± 0.013 in comparison with 896 ± 78 gram, 78.43 ± 0.64 % and 1.578 ± 0.038 of control group, respectively. Thus, COS can be potentially utilized as immunostimulants and growth promoter for aquaculture.
A pre-test analysis of ATLAS SBO with RCP seal leakage using MARS code
Authors: Pham Quang Huy , Lee Sang Yong , Oh Seung Jong
Published: September 2021

The accident in Fukushima Daiichi nuclear power plants shows the important of developing coping strategies for extended station blackout (SBO) scenarios of the nuclear power plants (NPPs). Many NPPs in United State of America are applying FLEX approach as main coping strategies for extended station blackout (SBO) scenarios. In FLEX strategies, outside water injection to reactor cooling system (RCS) and steam generators (SGs) is considered as an effective method to remove residual heat and maintain the inventory of the systems during the accident. This study presents a pretest calculation using MARS code for the Advanced Thermal-hydraulic Test Loop for Accident Simulation (ATLAS) SBO experiment with RCP seal leakage scenario. In the calculation, the turbinedriven auxiliary feed water pumps (TDAFPs) are firstly used after SBO initiation. Then, the outside cooling water injection method is used for long term cooling. In order to minimize operator actions and satisfy requirements of APR1400 emergency operation procedure (EOP), the SGs Atmospheric Dump Valve (ADV) opening ratio, auxiliary feed water (AFW) and outside cooling water injection flow rates were investigated to have suitable values. The analysis results would be useful for performing the experiment to verify the APR 1400 extended SBO optimum mitigation strategy using outside cooling water injection.

Authors: Ho Nguyen Thanh Vinh , Le Vinh Vinh , Nguyen Nhi Dien , Nguyen Kien Cuong , Huynh Ton Nghiem , Tran Quoc Duong , Nguyen Tien Vu
Published: September 2021

VVR-KN is one of the low-enriched fuel types to be considered for a new research reactor (RR) of a Centre for Nuclear Energy Science and Technology (CNEST) of Vietnam. This fuel type was qualified by a lead test carried out with three fuel assemblies (FAs) in 6-MWt WWR-K research reactor at the Institute of Nuclear Physics, Kazakhstan. VVR-KN fuel was then used for conversion of the WWR-K reactor core from highly-enriched to low-enriched uranium fuel and the reactor was successfully commissioned in September 2016. PLTEMP is a thermal-hydraulic code with plate and coaxial tube models that seems to be suitable for VVR-KN fuel type. Before using PLTEMP code for thermal-hydraulics analysis of the new RR, a calculation for code validation was performed based on the data of the VVR-KN fuel lead test. First, MCNP5 code was used to calculate the power distribution of WWR-K reactor core with lead test fuel assemblies (LTAs) at the core center. Then, thermal-hydraulics parameters of the LTAs were obtained by using PLTEMP code together with calculated data of the power distribution and the lead test conditions. A comparison between the analytic results and the lead test data was made to confirm the suitability of PLTEMP code for thermal-hydraulics analysis of VVR-KN fuel under forced convection and downward flow conditions.

Authors: Tran Ngoc Vuong , Luong Manh Hung , Nguyen Dinh Dang
Published: September 2021

Zinc scrap is a source of raw material for zinc oxide production. However, to qualify the requirement of raw material for zinc oxide (99.5%) production, refining this source is needed. Many methods are considered such as rectification, chemical method, etc., but difficult to apply on an industrial scale. This workfocused on the investigation of the influence of temperature and time factors for asessing the possibility of applying liquation method for the purification of impurities from scrap zinc.The experiment results show that the optimum temperature of liquation to remove Pb,Fe from zinc scrap is in the range of 440-450°C, the optimal time of the process is 8h for the pot with 8cm in height and 6cm in diameter (the quantity of raw zinc sample is about 2kg / batch), then we can obtain about 80% of zinc metal with an average Zn content of about 97, 0%, both Pb and Fe content decreased to a range from 0.35 to 0.4%, and 1.0 to 1.1%, respectively, which meet the requirement of raw materials for the production of high quanlity ZnO ( 99,5 %). Based on the parameters obtained on lab-scale, a trial on pilot scale of 250 kg / batch was conducted, The result confirms that the quality of the products meets the requirement of raw materials for production of high quality ZnO (99.5%) and a technology process for refining zinc scrap by the liquation was proposed.

Authors: Luu Xuan Dinh , Nguyen Thanh Thuy , Le Ba Thuan , Le Thi Mai Huong
Published: September 2021

The solvent extraction is one of the most common method for separating Th from solution. Primary amine has higher selectivity for the extraction of Th(IV) than U(VI) and RE(III) in sulfate media. N1923 (a primary aliphatic amine with amino nitrogen linked to a secondary carbon consisting of branched alkyl groups in C19–23 range) is commonly used to extractTh. At room temperature using 0.1M N1923 amine as solvent in this work, the results showed thatthorium maximum extraction capacity was about 2.5g/L with concentration of sulfuric acid in the aqueous phase was 1M and for 3 minutes shaking. At room temperature for 3 minutes shaking the best conditions for scrubbing process was using the mixture of acids H2SO4 0.2M and HNO3 0.1M, result inover 75%, Th was scrubbed in the aqueous phase only 0.7%. The separation of Th from leachate of monazite sulphation process was carried out on a multistage continuous flow extraction device (12 boxes), the thorium purity was 98%. Therefore, the use of amine solvents can purify thorium from rare-earth solutions in a sulfate medium

Published: September 2021

With the advent of the Spiral-2 linear accelerator and the associated S3 spectrometer at the Ganil laboratory in France, new realms of intermediate-mass N=Z and very heavy nuclei will soon become available for research in nuclear structure. After their production and selection in the spectrometer, the ions of interest will be stopped in a buffer gas, neutralised, resonantly re-ionised, cooled and bunched. This will bring us in an adequate position to perform laser spectroscopy, mass measurements and decay spectroscopy of their ground and isomeric states. In this contribution we report on the ongoing commissioning of the detector set-up.

Authors: Peng Hong Liem , Donny Hartanto , Yoshihisa Tahara , Naoyuki Takaki
Published: September 2021

An investigation on the nuclear transmutation of elemental long-lived fission product (LLFP) in a fast reactor is being conducted focusing on the I-129 LLFP (half-life 15.7 million years) to reduce the environmental burden. The LLFP assembly is loaded into the radial blanket region of a Japanese MONJU class sodium-cooled fast reactor (710 MWth, 148 days/cycle). The iodine element containing I-129 LLFP (without isotope separation) is mixed with YD2 and/or YH2 moderator material to enhance the nuclear transmutation rate. We studied the optimal moderator volume fraction to maximize the transmutation rate (TR, %/year) and the support factor (SF is defined as the ratio of transmuted to produced LLFP). We also investigated the effect of LLFP assembly loading position in the radial blanket and the severe power peak appeared at the fuel assembly adjacent to the LLFP assembly.

Published: September 2021

The paper presents the calculation results in re-design of neutron trap of the Dalat Nuclear Research Reactor (DNRR) for I-131 radioisotope production using TeO2 target. The new design permits for loading more TeO2 capsules from 9 to 12, 15 and 18 in the neutron trap. The enhancement of radioisotope production was implemented by re-arrangement of the neutron trap without changing the dimension or geometry of irradiation capsules. By using neutronics computer code as MCNP6, the obtained calculation results of I-131 activity in 6 investigated cases showed that the new design by the re-arrangement of the neutron trap can be used effectively for radioisotope production with thermal neutron flux in average range from 5.3×1012 to 1×1013 n/cm2.s and the total activity of I-131 isotope was increased from about 19.2% to 38.8% comparing with the original design using 9 capsules. The negative reactivity insertion was from 0.60 βeff to 0.96 βeff when loading capsules that also met the safety requirements of operational conditions of the DNRR.

Published: September 2021

This paper presents a model development of the Dalat Nuclear Research Reactor (DNRR) loaded with low enriched uranium (LEU) fuel using the Serpent 2 Monte Carlo code. The purpose is to prepare the DNRR Serpent 2 model for performing fuel burnup calculations of the DNRR as well as for generating multi-group neutron cross sections to be further used in the kinetics calculations of the DNRR with a 3D reactor kinetics code. The DNRR Serpent 2 model was verified through comparing with the MCNP6 criticality calculations under different reactor conditions. The parameters to be compared include the effective neutron multiplication factor, radial and axial powerdistributions, and thermal neutron flux distributions. The comparative results generally show a good agreement between Serpent 2 and MCNP6 and thus indicate that the DNRR Serpent 2 model can be used for further calculations of the DNRR.

Streptococcus sanguinis (s.sanguinis) is one of the normal flora in the oral cavity. These bacteria act as a pioneer in forming plaques that cause most dental and oral diseases. It takes an antibacterial agent to be able to inhibit the clips of the plaque. One of the herbal plants that have been known to have antibacterial power is the mint leaf (Mentha Piperita L.). The antibacterial potency of this plant comes from its chemical compound content, such as flavonoids, polyphenols, tannins, and menthols. This study aimed to determine the inhibitory of mint leaf extract on the growth of Sanguinis. An experimental laboratory carries out research. Tests were carried out using the diffusion method in four test groups, namely mint leaf extract with a concentration of 2.5%, 5%, 7.5%, and 10%, and one control group that uses DMSO. Each treatment group repeated five times on the Mueller-Hinton media (MHA) using disk paper and incubated for 24 hours. The inhibition zone can be seen in the transparent area formed around the disk paperand then measured using the Sorong term to find a large diameter. Statistical analysis was carried out using the Kruskal-Wallis test. The study results that the largest inhibitory zone diameter was obtained in a test group with a concentration of 10% (16.39 mm), while the lowest diameter in the control group (4.89 mm) 10% concentration was the highest among all test groups. The DMSO did not have an antibacterial effect. The higher the concentration of an antibacterial compound, it will also increase its effectiveness.

The chronological age of a person can not provide sufficient information. We can use the dental age in panoramic radiographs to know the growth process appropriately compared to The London Atlas of the Alqahtani method. Children aged 6-12 years have various factors that can affect the velocity in tooth growth and development, such as male and female. This study aims to determine the chronological patient's age differences with dental age based on the Alqahtani method on a panoramic radiograph at Unjani Dental and Oral Education Hospital. This type of research is Analytical Observational with the Cross-Sectional Study method. Research subjects were obtained from all medical records panoramic radiographs with 72 panoramic radiographs aged 6-12 years, divided into 36 male patients and 36 female patients. Differences in chronological age with dental age were analyzed statistically using the Mann-Whitney test and Wilcoxon test, previously tested for the normality using Kolmogorov- Smirnov. The results showed a significant difference between chronological age and dental age by gender and in all patients at the Unjani Dental and Oral Education Hospital (p<0,05). Based on the analysis of the data obtained, all patients in RSGMP Unjani aged 6-12 years have different dental developmental growth processes, and the dental development growth of female patients was faster than male patients. It can be concluded that the dental age is not always comparable with chronological age because of various factors such as gender, genetics and environment, which can affect the dental age.

Discoloration (extrinsic and intrinsic) reduce the beauty of someone's appearance and confidence. Discoloration affected the increased aesthetic treatment needs in dentistry. Discoloration can be treated by teeth whitening procedures. Teeth whitening can be done with dental bleaching from the application of chemicals on the surface of the teeth. However, dental bleaching has side effects such as reduce the amount of calcium, phosphate and fluoride in tooth enamel, reduce enamel hardness, enamel surface roughness, and dental hypersensitivity. Belimbing wuluh is one of the herbal ingredients to minimise the risk; it contains oxalic acid, a natural peroxide compound. This study purposed to determine the effect of belimbing wuluh gel extract in increasing the degree of teeth brightness colour by in vivo in rabbits. This study used an experimental analytic method with 27 rabbits' incisors, divided into three groups: 50% belimbing wuluh gel, 40% oxalic acid gel, and negative control group. Rabbits' incisors were previously coated in a transparent varnish on the specified area. Teeth bleaching is done for 4 hours in 14 days. Colour measurements used camera and ring-light, which MATLAB will convert. The data were analysed statistically with One way ANOVA followed by a post-hoc NSK test (p <0.05). The result showed that belimbing wuluh gel extract caused an increase in the teeth colour's brightness (p = 0.0030). So, it can be concluded that belimbing wuluh gel extract affects increasing the degree of teeth brightness.

In recent years, experiential learning modality has become an integral part of business education in international programs. Although extensive research has been conducted in the experimental learning arena, the research regarding international students, especially the rapidly growing number of Asian students, with a significant percentage from China, is still limited. This study utilized a mixed-methods design using Kolb Experiential Learning Theory (ELT) to investigate the preferred experiential learning (EL) pedagogical practices for Asian students while studying at North American universities. This study revealed that students with a positive attitude toward EL could fundamentally strengthen their learning outcomes. In contrast, well-balanced learning styles should be emphasized instead of ranking the priority of learning preferences or taking only one learning approach. The limitations of the study and the future direction of related research are also presented.

Introduction: Epidemiological data from patients with COVID-19 has been recently published in several countries. Nationwide data of hospitalized patients with COVID-19 in Greece remain scarce. Material and methods:This was an observational, retrospective study from 6 reference centers between February 26 and May 15, 2020. Results: The patients were mostly males (65.7%) and never smokers (57.2%) of median age 60 (95% CI: 57.6–64) years. The majority of the subjects (98%) were treated with the standard-of-care therapeutic regimen at that time, including hydroxychlo-roquine and azithromycin. Median time of hospitalization was 10 days (95% CI: 10–12). Twenty-five (13.3%) individuals were intubated and 8 died (4.2%). The patients with high neutrophil-to-lymphocyte ratio (NLR) (> 3.58) exhibited more severe disease as indicated by significantly increased World Health Organization (WHO) R&D ordinal scale (4; 95% CI: 4–4 vs. 3; 95% CI: 3–4, p = 0.0001) and MaxFiO2% (50; 95% CI: 38.2–50 vs 29.5; 95% CI: 21–31, p < 0.0001). The patients with increased lactate dehydrogenase (LDH) levels (> 270 IU/ml) also exhibited more advanced disease compared to the low LDH group (< 270 IU/ml) as indicated by both WHO R&D ordinal scale (4; 95% CI: 4–4 vs. 4; 95% CI: 3–4, p = 0.0001) and MaxFiO2% (50; 95% CI: 35–60 vs. 28; 95% CI: 21–31, p < 0.0001). Conclusion: We present the first epidemiological report from a low-incidence and mortality COVID-19 country. NLR and LDH may represent reliable disease prognosticators leading to timely treatment decisions.
Działania hoteli w czasie i po pandemii. Przegląd literatury
Authors: Gołembski Grzegorz
Published: September 2021

Celem artykułu jest zidentyfikowanie skutków pandemii dla działalności hotelarskiej, m.in. strat hoteli wynikających z konieczności zamknięcia obiektów. Straty te mają wymiar ogólnoświatowy. W badaniach zastosowano metodę krytycznej analizy literatury światowej poświęconej sposobom ograniczenia negatywnych skutków pandemii dla hoteli. Wskazano znaczenie zdolności innowacyjnych w hotelach, które w dużej mierze zależą od zdolności innowacyjnej pracowników. Zwrócono uwagę na działania zwiększające bezpieczeństwo zdrowotne klientów i personelu. Podkreślono także rolę CSR (corporate social responsibility), która wpływa pozytywnie nie tylko na pracowników, ale także na klientów i społeczność lokalną. Z przeprowadzonych badań wynika, że podstawą przetrwania hoteli po pandemii są zdolności innowacyjne (zdolność do kreowania, poszerzania i modyfikacji zasobów). Zadaniem priorytetowym menedżerów jest stworzenie warunków, w których pracownicy mogą uwolnić swój potencjał i podjąć ryzyko promowania ciekawych pomysłów.
