The ambient air monitoring of PCDDs/PCDFs and dl-PCBs using passive air samplers in a residential urban area in Hanoi between 2012-2020 was deteminated. The seasonal variations of PCDD/PCDF and dl-PCB levels in ambient air in three periods: between Spring 2012 and Autumn 2015, from Winter 2015 to Autumn 2018, and between Winter 2018 and Autumn 2020 are similar to a V-shape with the highest peak in winter, then decreasing gradually in spring, bottoming in summer and rising again in autumn. The upward temporal trends of PCDD/PCDF and dl-PCB pollution, and total TEQD/F&DL, total TEQD/F and total TEQDL has been confirmed over time. The concentrations of total PCDFs were dominant and were approximately 1.0 to 9.3 times higher and 2.4 times higher on average than total PCDDs. Total dl-PCBs were 5.8 to 38 times higher and 17 times on average higher than the total toxic PCDDs/PCDFs. The PCDD/PCDF congeners contributed 83% to 95% of the total TEQ value. The phenomenon of temperature inversion not only causes seasonal air pollution but also increases the concentration of PCDDs/PCDFs and dl-PCBs with a narrower range but at a higher average levels.

This study was performed to evaluate the effect of isoflavones extracted from soy germ on menopausal symptoms associated with 4-vinyl cyclohexene diepoxide (VCD)-induced follicular failure in mice. Total isoflavone extract (CE) and aglycone-enriched extract (TPCa) from soybean embryos 50 mg/kg/day were both able to improve female physiological characteristics positively. The CE sample was able to slightly increase the uterine volume (p<0.001), increase the number of primary follicles (p<0.001), and increase the estradiol content (p<0.001). TPCa sample also can slightly increase uterine volume (p<0.05), increase the number of primary follicles (p<0.001), and increase estradiol content (p<0.001). These results suggest the potential for using isoflavones from soybean embryos in the prevention and treatment of menopausal symptoms - more effectively and safely than traditional hormone therapy.

Cases of detection of RNA or ELISA markers of West Nile virus (WNV) have been recorded in many countries of Southeast Asia. At the same time, there were no reports of outbreaks of fevers caused by WNV. Perhaps this is due to the asymptomatic or very mild course of the disease or to the focus of the health systems of these countries on other viral fevers. In this work, for the first time in Vietnam, West Nile virus (WNV) RNA was detected in poultry. WNV RNA was found in three lung samples of chickens from Nghe An province collected in 2017. The isolates belonged to lineages 1a and 2, responsible for many WNV outbreaks in Europe and North America and therefore require close attention.

Hepatitis B (HBV), C (HCV), and D (HDV) are common infectious diseases that cause serious health consequences and lead to death due to dangerous complications such as acute liver failure, cirrhosis, and liver cancer. According to The World Health Organization estimates, there were about 354 cases of chronic HBV and HCV infection in 2019. Vietnam is a country that has high rates of HBV infection and an estimated 8.6 million people are infected with HBV. In this study, we identified the prevalence rates of HBV, HCV, and HDV in 1248 serum samples collected from healthy among young adults aged 18 to 29 years old (mean age: 20.3 ± 1, 4) in Thai Nguyen and Da Nang in 2018 by ELISA. We also identified the HBV genotype in HBV-DNA-positive samples, sequenced the preS/S gene, and analyzed the phylogenetic tree. The study result showed that the detection rate of HBsAg antigen is 3.5% and total anti-HBc is 24.9%, the detection rate of anti-HCV is low and the anti-HDV is not decided in the cohort of (18-29 years old) young adults in Thai Nguyen and Da Nang. The phylogenetic analysis showed there is a circulating of genotype B and genotype C. The rate of HBV belonging to the B4 subtype is 78.9% and belonging to the C1 subtype is only 21.1%. 15/19 samples of recombinant HBV detected is the genotype B4/C. The rare mutant G145K belonging to a vaccine escape mutation is identified in one of the HBV samples in Thai Nguyen; the core promoter double mutation A1762T/G1762A are identified in one of the HBV sample; and only one mutation A1762T is identified in one of the HBV sample.

This article presents the results of research on surface treatments for SKD61 steel aiming to fabricate the core-pin used in high pressure aluminum casting. The tempered SKD61 sample with a surface hardness of 597 HV0,1 was nitrided to obtain a surface hardness of 1155 HV0,1 and the thickness of the nitrided layer was 80 µm. The Cr/CrN multilayer coatings were deposited by cathodic Arc-PVD on nitrided and tempered SKD61 substrates so that the hardness reached 1538 and 1755 HV0,1 respectively. The coating thickness obtained was approximately 2 µm for both coating samples. The results showed that the Cr/CrN multilayer coating significantly improved the corrosion and abrasion resistance of the tempered steel substrate and the gas-nitrided substrate. The PVD coating on nitrided substrate exhibited adhesion to the substrate HF1-HF2 level, while the coating on the tempered substrate only obtained HF6 level according to VDI 3198 standard.

The aim of the paper was to investigate the mechanical properties of AlTiN, TiAlN coatings deposited by the arc-PVD method on SUS304 stainless steel substrate. The coating's surface morphology and structure were examined using a profilometer, scanning electron microscopy, energy dispersion spectroscopy and X-ray diffraction. Adhesion of the deposited coatings was determined by the Rockwell test. The sliding wear resistance of AlTiN and TiAlN was much higher than that of the stainless steel sample. The deposition of PVD film on a stainless steel substrate reduces the coefficient of friction by 3-6 times. The sliding wear mechanism of AlTiN and TiAlN coatings was different, AlTiN - the vertices of the coating were obtused, grooved, and scratched along the wear, with less material displacement in both directions along the wear trace; TiAlN - the coating was strongly plowed, the material was worn and forced in both directions of the sliding wear trace.

This paper presents the results of a study on the corrosion of steel reinforcement in concrete pore solutions contaminated with chloride ions. With increasing chloride concentration, the open-circuit potential and the anodic polarization curve shift towards more negative potential values, the passive potential region of the anodic polarization curve decreases. The corrosion rate of reinforcement was evaluated according to the linear polarisation resistance technique. Accordingly, the corrosion rate of steel reinforcement is 4.53 µA/cm2 in the solution containing 1 M Cl-. In this study, galvanic electrochemical sensors with low carbon steel anodes and copper cathodes were developed. In an environment with no or low Cl- concentration, where the reinforcement is passivated, the corrosion current density of the sensor does not exceed 10.0 µA/cm2. The corrosion current of the sensor increases sharply under cathodic control with increasing chloride content. Thus, the developed sensor has a high sensitivity to chloride corrosion and is capable of detecting pitting corrosion caused by chlorides at an early stage.

In this study, the consortium of filamentous fungi affecting the metal protection of 04 types of grease (GOI/VN grease, salt-tolerant grease AMC-3/VN, PVK/VN grease, Russian PVK grease) was identified. Six steel-covering grease types exhibiting protection against fungal infections were taken for fungal isolation. Seven strains of filamentous fungi were isolated, characterized by colony morphology, analysis of ITS1-5,8S-ITS2 sequences, and abilities to produce extracellular enzymes (protease, amylase, cellulase, lipase). Besides, the influence of filamentous fungi on metal protection was evaluated by measurement of rust portfolio on metal surface after degreasing by using images ImageJ v.1.51 software. Among isolated strains, 07 isolates of filamentous fungi showing varieties in morphological colonies were selected and taxonomically identified as Penicillium chermesinum, Penicillium cuddlyae with over 98% similarity of ITS1-5,8S-ITS2 sequences compared with related ones deposited on GenBank (NCBI). Of those, 02 strains (M1.1 and M4.1) were capable of producing 4 types of extracellular enzymes. When utilizing Image J software to examine the effects of fungal isolates on the protective capabilities of grease covering materials against metal corrosion, rust spots with variable densities between 1.30%-18.66% appearing on the surface of CT5 steel were found to be formed by fungal attacks. The findings in present study therefore provide a fundamental basis for the effects of fungal growth on grease decomposition at the Hoa Lac Thach That/ Ha Noi testing area and further studies on damages caused by fungi to steel-covering greases as well as corrosion of the metal surface.

Published: May 2023

Hadirnya struktur geologi yang berupa ketidakmenerusan/diskontinuitas pada massa batuan yang diakibatkan oleh gaya eksogen dan endogen di bumi, merupakan salah satu faktor pengurang dari kestabilan lereng. Perbedaan kekasaran permukaan bidang diskontinu (dalam penelitian ini adalah kekar) dan panjang kekar (persistensi) merupakan properties yang tidak dapat diabaikan dalam penilaian kestabilan lereng. Pada penelitian ini, persistensi dikelompokkan menjadi dua, yaitu persistensi lebih dari 3m (Medium-Panjang) dan persistensi kurang dari 3 m (Pendek-Medium). Hasil pengukuran diperoleh nilai Joint Roughness Coefficient (JRC) yang merupakan kuantifikasi dari kekasaran pada kekar Medium-Panjang (MP) berada pada nilai 4-6 (sebanyak 71,4% dari total kekar terukur) dan sisanya bernilai 0-2, 2-4, 8-10, dan 12-14 berdasarkan skala Barton-Bandhis (1977). Dalam proses analisis kestabilan lereng, kekasaran bidang diskontinu M-P merupakan hasil pengukuran aktual yang terekam pada sayatan. Adapun kekar Pemdek-Medium (P-M) digambarkan sebagai joint network dengan nilai JRC kombinasi 4 dan 8. Hasilnya, kondisi lereng penelitian dinilai aman berdasarkan pada enam sayatan yang dianalisis. Nilai Strength Reduction Factor (SRF)yang merupakan nilai faktor keamanan (FK) paling kecil berada pada nilai 1,89 dan nilai probabilitas kelongsoran berada pada nilai 5,81%. Kedua nilai tersebut masih berada dalam range aman berdasarkan Kepmen ESDM No. 1827/2018.

Hydatid disease caused by Echinococcus Granulosus usually occurs in form of cystic lesions in the livar and the lung. Central nervous system involvement in hydatidosis occurs in 0,9 % to 2, 1 % of cases. Cerebral hydatidosis is a pediatric disease and 93 % of cerebral cysts are found in children under the age of 17 years. lnfestation usually occurs very early in the life and because of slow growth of the cysts it usually takas several years for symptoms to develop. Primary hydatid cysts of the brain are usually single. We couldn't coincide with the occurrence of a primary multiple hydatid cysts of the brain in an adult in the literature before.
