Authors:   Institute of oriental studies, Russian academy of sciences (MOSCOW), Popov Aleksandr
Published: March 2022

The article analyses the current situation in the oil and gas sector of Indonesia that used to be a big oil exporting country and a member of OPEC but some years ago became a net-importer of oil. The demand of the growing Indonesian economy for oil much exceeds the capacities of its oil industry and each year Indonesia has to spend great amounts of money for importing oil and oil products. The government is trying to take all possible measures to attract new investments in this field but the lifting of oil continues to drop first of all due to the absence of proper investments into the exploration for oil and gas. The situation with the gas lifting is much better but a large part of its reserves first of all situated in the South China Sea can not used properly due to a high content of carbon dioxide in it. Besides, in this area Indonesian companies carrying out the exploration for oil and gas faces a military presence of China that regards it as its own territory.

Published: March 2022

The study was conducted to evaluate the effects of a medicinal plant mixture (MP) (60% Bindens pilosa L., 15% Urena lobata L., 15% Pseuderanthemum palatiferum, 5% Ramulus Cinnamomi, and 5% Illicium verum Hook. f.) as a feed additive to promote the growth performance and meat quality of grower-finisher pigs. Forty-eight crossbred pigs (Duroc × (Landrace × Yorkshire)), with initial live body weights of 30.3 ± 1.42kg, were randomly allocated to four dietary groups, with three replicates of each group and four animals per replicate. The experimental pigs were fed a basal diet supplemented with MP powder at 0, 20, 40, or 60 g kg-1 of feed (T0, T20, T40, and T60) for 15 weeks. The growth performance, carcass quality parameters, chemical composition, fatty acids, and cholesterol contents of the pig meat were measured. There were no statistical differences (P> 0.05) in the final live body weight, overall average daily gain, average daily feed intake, and feed conversion ratio among the control and MP treatments. MP supplementation significantly increased the protein content (P = 0.02) and decreased the cholesterol content (P = 0.04) of raw longissimus dorsi muscle. The obtained results indicate that the dietary MP supplementation tested could have the potential to improve meat quality and decrease the cholesterol content in pork with no adverse effects on the growth performance.

Authors: Cuong Tran Quoc , Yen Duong Thuy
Published: March 2022

Bighead catfish, Clarias macrocephalus, is an important species for aquaculture. Nevertheless, information on population variation in their reproductive characteristics and larval growth is limited. This research aimed to evaluate the reproductive performance and larval growth of three bighead catfish broodstock strains collected in Ca Mau (CM) and Hau Giang (HG) provinces (wild strains), and Can Tho (CT, domesticated strain) in the Mekong Delta, Vietnam. The three groups of fish were cultured under optimal maturation conditions in a recirculating system for three months. Then, 16-18 pairs from each broodstock source were artificially propagated. Relative fecundity differed among the sources, from 48,600 (CM) to 69,300 (CT) eggs/kg female (P< 0.05). The three broodstock sources also differed in fertilization and hatching rates. In addition, wild breeders (CM and HG) had slightly larger eggs, and their offspring had larger sizes at hatching and larger yolk sac volumes than those of cultured (CT) breeders (P< 0.05 for all tests, except for egg sizes). In the larval rearing experiment, 2 day-old larvae were stocked in 40 L-rectangle tanks (1,000 individuals/tank) in a recirculating water system. Larvae were fed with Moina combined with commercial feed. After 40 days, survival rates of the three fish groups ranged from 46.7% (CT) to 54.7% (HG). The final weights varied from 177 mg (CM) to 201 mg (HG) and 202 mg (CT). However, the effects of broodstock sources on the growth and survival rates of the offspring were not statistically significant (P> 0.05).

Published: March 2022

The trophic levels in urban lakes are typically based on the forms of nutrition and phytoplankton communities in the lakes. In this study, comparisons between eutrophication indices and the water quality index (VN-WQI) were used to classify the water quality of 20 lakes in Hanoi, Vietnam. The results showed that the water quality ranged from very bad to poor. High levels of the eutrophication phenomenon in terms of total N and P were observed in all sampling sites. Cyanobacteria was the dominate algae phylum making up 65.78% of the total population, whereas Chlorophyta (including 19 genera) was the most diverse phylum. The density of the algae was 5,000-14,000 cells mL-1 and the chlorophyll-a level was 10-40 µg L-1. Based on this information, the water quality levels in the lakes were classified from eutrophic to polytrophic. The Trophic Status Index (TSI) and Trophic Level Index (TLI) values ​​were 66.9-86.0 and 54.4-76.0 points, respectively, corresponding from eutrophic to extreme-trophic. Classifications based on algae community structure indices were from oligotrophic to eutrophic, similar and consistent with the TLI classifications. According to the results in this study, the TLI was found to be more accurate and precise than the other indices. It is recommended that the TLI is an applicable tool to classify eutrophication in urban lakes.

Published: March 2022

The Afforestation and Perennial Tree Plantation Project were implemented in several mountainous areas in Dien Bien province, Vietnam, for many purposes such as providing agricultural products, increasing incomes for the people in the projected areas, and reducing shifting cultivation. Based on these reasons, the central and local governments implemented several policies and subsidies for the growers, including rice subsidies for ethnic minorities who planted forests to replace shifting cultivation; investment support for planting protective forests and special-use forests; and providing seedlings. This article aimed to provide a clear view of the supporting policies in the Afforestation and Perennial Crops Project and its effects on the local people’s livelihoods in Dien Bien province of Vietnam. By analyzing the types of the capital of the livelihood assets (human capital, natural capital, financial capital, physical capital, and social capital), indicators of each capital type were chosen and scored in the context of achieving sustainable livelihoods. The results identified that the government has issued several policies to help the investors and farmers involved in this project. However, there were some concerns about the policies in practice, for example, the low percentage of dividend sharing for farmers, unclear land use rights, and inadequate applications of the policies in reality. In evaluating the livelihood assets, significant differences were found in the sustainable livelihood index gained between the rubber-based and non-rubber-based groups.

Authors: Nga Nguyen Thi Thu , Bac Nguyen Xuan
Published: March 2022

Anthracnose is the most prevalent and devastating fungal disease both before and after harvesting of mango worldwide. The anthracnose pathogen infects fruit in the field and remains quiescent until the fruit is harvested and starts to ripen. This is the major constraint in the commercialization of fresh mango. Currently, this is the first study that has evaluated the impact of a chitosan-based coating with Aloe vera gel and papaya leaf extracts on the postharvest quality of mango fruit infected with anthracnose under ambient storage conditions. After coating and drying, mangoes were artificially inoculated with Colletotrichum gloeosporioides (105 conidia per mL) and then air-dry, placed in perforated open-top plastic baskets, and stored at room conditions (average temperature 34.3 ± 2°C and relative humidity 71.8 ± 10%). The respiration rate, weight loss, color, firmness, vitamin C content, and spoilage rate were measured during storage. The results showed that the coating formula made with 0.5% chitosan combined with 0.3 % Aloe vera gel and 0.2% papaya leaf extracts was the most effective formula for maintaining postharvest quality and minimizing the spoilage of mango fruit infected with anthracnose under ambient conditions. Further in-depth studies are needed to determine both the mode of action in the successful commercialization of this new edible coating in the fresh mango fruit industry.

Authors: Peng Xi , Zhou Jiu
Published: March 2022

In order to inherit and innovate traditional weft-backed structure jacquard fabric, a design principle and method of digital jacquard with 2:1 weft-backed structure was proposed. Based on the in-depth analysis of the characteristics of the traditional 2:1 weft-backed structure, four digital structural models (A1, A2, B1 and B2) with shaded weave were built by using digital jacquard technology. It lays a theoretical foundation for the creation of four kinds of digital jacquard fabrics with colour shading effects. In addition, the combined application of model A1 and model B1 was taken as an example to illustrate the design method. The resulting fabric had a delicate and natural colour shading effect. And its main and minor motifs were clearly distinguished. Meanwhile, the colour expression was increased while the yarn utilisation and production efficiency were improved. The principle and method proposed in this paper can create a wide variety of digital jacquard fabrics with colour shading effects, which provides ideas for the structural innovation and variety design of traditional jacquard fabrics.

Aim: to assess the retina (including peripapillary retinal nerve fiber layer/RNFL and retinal vessel diameter) in patients with tuberculosis (TB) or HIV/TB coinfection in the lack of abnormalities detected by standard eye exam using optical coherence tomography (OCT). Patients and Methods: all patients were divided into three groups. Group 1 (n=19) included patients with HIV/TB coinfection. Group 2 (n=18) included patients with pulmonary and extrapulmonary TB. Group 3 (n=20) included healthy volunteers (controls). All patients underwent standard eye exam and OCT (iVue-100 v3.2, Optovue, USA) to measure peripapillary RNFL thickness, central macular thickness, and the firstorder retinal vessel diameter (eight vessels). Results: OCT demonstrated greater peripapillary RNFL thickness in the nasal sector (by 13.4–18.3%) and central macular thickness (by 4.0– 7.5%), narrowing of retinal arteries, and enlargement of veins (predominantly temporal). These patterns may illustrate retinal microcirculation in the setting of a pathological condition (HIV/TB, including highly active antiretroviral therapy [HAART]) and be a harbinger of further abnormalities of ocular structures and central nervous system. Conclusion: OCT identifies changes in vessel diameter, central macular thickness, and peripapillary RFNL thickness before visual disturbances in preclinical eye changes in patients with HIV/TB coinfection. Keywords: HIV, tuberculosis, optical coherence tomography, calipermetry, retina. For citation: Burylova E.A., Demin A.P., Skornyakov S.N., Sabadash E.V.

Authors: Gomathi R , Ashok M , Menaka M , Venkatraman B
Published: March 2022

Curved glass fiber–reinforced polymer (GFRP) composites are superior to alloy-steel pipes due to their excellent corrosive resistance properties, finding wide applications in the transportation of petrochemicals, chemical storage tanks, and power and water-treatment plants. Among the defects found in GFRP pipes, internal pitting or wall loss is one of the most severe, caused by material deterioration and the friction of small particles in the transfer fluid. This study investigates these in-service discontinuities using a pulsed thermal nondestructive evaluation technique. The paper focuses on the quantification of defect depth using the temperature peak contrast derivative and defect sizing using the full width at half maximum method. Further, the paper investigates the ability of pulsed thermography to estimate pitting or wall-loss defects at various depths and sizes through simulation and experimentation. Thermographic signal reconstruction images are used for quantification of defects at a deeper depth. The results of the present study are then compared with well-established ultrasonic C-scan results.

kIBERNETSkA VARNOST V DRUŽBI IN DELOVANJE kRITIČNE INFRASTRUkTURE – ANALIZA STANJA NA OBRAMBNEM PODROČJU V REPUBLIkI SLOVENIJI
Authors: ČALETA DENIS , ROLIH GORAZD
Published: March 2022

Pojav asimetričnih oblik ogrožanja nacionalne in mednarodne varnosti izhaja iz popolnoma drugih predpostavk in dojemanj temeljnih konceptov zagotavljanja varnosti, ki je še nekaj časa po koncu hladne vojne temeljila na statičnem pristopu do obvladovanja konvencionalno opredeljivih vrst groženj. Spreminjajoče se družbene razmere in napetosti, ki jih je prinašal hiter tehnološki razvoj, so posamezna družbena okolja našle popolnoma nepripravljena na spopadanje z novo globalno varnostno situacijo. Zaradi navedenega bo treba kibernetskim grožnjam nameniti posebno pozornost. Učinkovito obvladovanje teh groženj je pomemben pogoj za nemoteno delovanje informacijsko-komunikacijskih sistemov, ki delujejo v okviru kritične infrastrukture. V Republiki Sloveniji bo treba ukrepe zoperstavljanja kibernetskim grožnjam načrtovati in izvajati s sistemskim pristopom, saj si je zaradi omejenosti finančnih, kadrovskih in tehnoloških potencialov nemogoče zamisliti drugačno pot. Pri tem pa mora imeti obrambno področje, vključno s Slovensko vojsko, pomembno vlogo.

Scientific research activity (SRA) in comprehensive school is not a new phenomenon. Similar actions have been paid attention at various stages of education. Changes in the quality and quantity of the current stage of society development show a different situation: the pace of life increases, the “turbulence” of the surroundings is observed, globalization and social and economical changes in various segments of society gain more power. At the moment, the education system in Lithuania and other countries is facing different changes. As for the reorganization of Lithuanian education system within the period of the last two decades, it seems to be an intensive and ambiguous process. Lithuania had to pose two fundamental challenges: first, to proceed from the so called “soviet” system of education the one based on national identity and experience, and second, to adapt the new system to the needs for modern society fully integrating the experience of international education. The adjustment of national and international components has remained the major problem of Lithuanian education system up to now.
