Authors: Le T. S. , Nguyen X. Q.
Published: January 2024

In Vietnam, the concept of “settling down, having a good career” becomes an important goal of each individual. It means having a stable place to live can be guaranteed when you get a job. Therefore, home ownership becomes a basic human right. In the current integration trend, when the opening to trade between countries around the world is deepening, the demand for house ownership is not only limited to Vietnamese citizens, but also to foreigners. Vietnam has also recognized the problem of foreigners owning houses in Vietnam, but there are still restrictions on the number of houses, the area of houses owned and other issues. Currently, the Government is implementing a policy to attract investment in housing in order to exploit the development potential of this field in Vietnam as well as to solve the outstanding housing problem and expand the housing market. Therefore, the issue of foreigners’ home ownership becomes an important concern and is one of the research subjects to implement this policy.

The article presents the provisions of Vietnamese law, international law on home ownership rights of foreign individuals and organizations in Vietnam, as well as conditions for foreign individuals and organizations to own housing in Vietnam, a guarantee of human rights. In addition, the article also points out to the shortcomings of the national legal regulation, thus making some recommendations to overcome the difficulties of the real estate market and housing development in Vietnam.

Authors: Silin Alexey V. , Satygo Elena A. , Maryanovich Alexander T.
Published: January 2024

The article provides a brief overview of the studies regarding changes in the structure and composition of teeth after eruption. The factors of degenerative changes in tooth structures and their relationship with non-carious lesions have been analyzed. The study makes emphasis on the tooth durability and the factors influencing tissue fatigue, explaining increased tissue wear due to local factors. Understanding mechanisms of metabolism of teeth hard tissues is the key to the stability of restorative treatments and occurrence of non-carious tooth lesions. The evolution of views on this problem is noteworthy. The literature review reveals the initial predominance of mechanical actions, abrasion, and mineralization. It is later complemented by a detailed analysis of the influence of destructive stresses and deformation due to mechanical factors. All the leading works of the 2000s are dedicated to analyzing the ultrastructural features of enamel that affect its mechanical characteristics and can explain both the characteristics of the shape and intensity of mechanical tooth wear during the functioning of the stomatognathic system, as well as the durability of the performed restorations. The literature review covers 74 sources over the past 15 years.

Published: January 2024

Synovial sarcoma of the retroperitoneum is a rare and aggressive tumor. In some cases, differential diagnosis between retroperitoneal sarcoma and adrenocortical cancer is difficult due to the similar clinical and intrascopic manifestations of these neoplasms. The final diagnosis is established based on the results of histological, immunohistochemical and genetic studies. The most important step in the treatment of synovial sarcoma is complete removal of the tumor. However, despite the radical nature of the intervention, the incidence of local relapse and metastasis remains high.
AIM: to conduct a retrospective analysis of the parameters of operated patients with synovial sarcoma of the retroperitoneum.
This study is aimed at studying the results of examination and surgical treatment of patients with synovial sarcoma of the retroperitoneal space who were hospitalized in the E.E. Eichwald Clinic surgical department of the North-Western State Medical University named after. I.I. Mechnikov.
The patients were assessed for hormonal status using an immunoassay to determine the levels of adrenocorticotropic hormone, cortisol, aldosterone, renin, normetanephrine and metanephrine in the blood, and a dexamethasone suppression test has been performed at a dose of 1 mg. High-performance liquid chromatography has determined 6 glucocorticoids in the blood serum: cortisol, cortisone, corticosterone, 11-deoxycorticosterone, 11-dehydrocorticosterone, 11-deoxycortisol. The urine steroid profile was studied in all the patients using gas chromatography-mass spectrometry. All the patients underwent computed tomography of the abdominal organs and retroperitoneal space with contrast, morphological and immunohistochemical examination of the removed material. The material was fixed in 10% neutral buffered formalin. The pieces were then subjected to standard wiring followed by embedding in paraffin. Sections 2–3 microns thick were prepared from the resulting blocks and stained with hematoxylin and eosin. Immunohistochemical studies were performed on paraffin sections. A panel of monoclonal antibodies was used: protein S-100 (poly), pancytokeratin (AE1/AE3), EMA, cytokeratin-8, -18, chromogranin A, synaptophysin, α-inhibin, SOX-10, CD99, TLE-1, bcl- 2, GATA-3. Postoperative outcomes and follow-up were assessed according to the information in the medical records and data obtained from a telephone conversation with each patient. Statistical processing of the results has not been out due to rare cases of the disease.

Published: January 2024

This study aimed to measure the impact of employees' job demands as a stressor on exhibiting their uncivil behavior at the workplace and the remedial role of self-efficacy for the detrimental effect of job demand on workplace incivility behavior. Research on employees' uncivil behavior in the workplace is crucial to understanding its causes, impacts, and potential interventions, enabling organizations to foster a respectful and productive work environment, enhance employee well-being, and optimize organizational performance. Employees of the Nepalese cooperative industry participated in a survey to gather empirical data. The perceptual cross-sectional data were analyzed using a positivist research methodology and deductive reasoning. Altogether, 495 responses were analyzed quantitatively using "Analysis of Moment Structure" (AMOS) software and graphically presented. The result revealed that employees' perceived job demand positively affected (B = 0.43, p < 0.001) their workplace incivility behavior. At the same time, self-efficacy had a negative impact (B = -0.32, p <0.001) on uncivil behavior at the workplace. In addition, self-efficacy moderated (B = -0.47, p <0.001) the connection between job demand and workplace incivility behavior. Job demands positively impacted incivility for employees with low self-efficacy, but the effect was insignificant for those with high self-efficacy. Moreover, employees with low perceived job demand exhibit higher workplace incivility behavior (WIB) when they have high self-efficacy compared to low self-efficacy. These findings have implications for addressing job demands and fostering self-efficacy to mitigate workplace incivility. Further avenues for research are discussed.

Authors: Puspawati Dewita , Abas Novel Idris , Permatasari Widowati Dian
Published: January 2024

This study examines personality traits, financial literacy, and risk tolerance for investment intentions. In addition, this study also examines the role of risk tolerance as a mediator in the influence of personality traits on investment intentions. A quantitative research method is used to measure personality traits, financial literacy, risk tolerance, and investment intention. A survey was conducted among young individuals in Indonesia. Respondents came from various regions in Indonesia, especially those from Java, Indonesia. The number of samples was 405 questionnaires. The results show that several personality traits, such as extraversion, neuroticism, and openness, affect investment intentions. However, the results show conscientiousness and agreeableness do not affect investment intentions. Researchers have found that extraversion and conscientiousness do not affect risk tolerance, but neuroticism, openness, and agreeableness do. Financial literacy and risk tolerance are also proven to affect investment intentions. When the mediation effect was tested, it was found that neuroticism, openness, and agreeableness affect investment intentions. On the other hand, risk tolerance does not act as a mediator variable between extraversion and investment intention. The practical implication of the study lies in assisting stock exchanges in developing countries to craft effective strategies for attracting Generation Z and Alpha investors, particularly during periods of economic volatility.

Published: January 2024

Background: Rice is a vital staple food for a large part of the global population and zinc deficiency poses health risks, particularly in rice-dependent regions. Studying genotypic differences in rice seed zinc content is vital for breeding zinc enriched varieties to address malnutrition and enhance food security. In the plant microbe partnership exploring the role of seed bacterial endophytes in influencing the plant physiology holds promise for Zn accumulation contributing to the broader goals of enhancing food quality, nutrition and crop production in a world facing increasing agricultural demands and challenges. Methods: Rice genotypes were surveyed and their seed zinc content was analysed using non-destructive X-ray fluorescence spectrometry. Surface sterilization of rice seed samples was performed to isolate endophytic bacteria, involving a series of treatments with distilled water, ethanol and sodium hypochlorite to remove surface microflora. The sterilized seeds were then macerated and diluted to obtain a countable number of colonies, which were subsequently spread-plated on nutrient agar, tryptic soy agar and soil extract agar to enumerate the different nutritional types of seed endophytic microflora. Result: In this study, 34 different rice genotypes, comprising traditional landraces and modern cultivars, were collected and analysed for their inherent zinc content. One variety in each category of low, medium and high seed Zn content was selected. The occurrence of all nutritional types of bacterial and their population was highest in the genotype Karuppunel followed by CO51 and ADT 39. Nutrient agar was found to promote a higher count of culturable bacterial endophytes compared to Tryptic soy agar and Soil extract agar.

In the present investigation, various cultivars of Ajuga iva were collected from different locations in Morocco in 2022. These cultivars were subjected to extraction using different solvents, namely water, ethanol and methanol, to obtain extracts from their aerial parts. The extracts were then analyzed to determine their total phenolic content, total flavonoid content, total sugar content, hydrolysable tannin content, condensed tannin content and antioxidant activity. The results obtained from the analysis revealed the following quantities for the different parameters: The total phenolic content ranged from 226.04±8.47 to 22.59±2.43 mg GAE/g dw, the total flavonoid content ranged from 22.27±0.11 to 3.35±0.006 mg QE/g dw, the total sugar content ranged from 38.78±2.56 to 2.88±0.18 mg/g dw, the reducing sugar content ranged from 7.17±0.45 to 0.41±0.007 mg/g dw, the hydrolysable tannin content ranged from 12.25±0.017 to 0.75±0.15 mg TAE/g dw, the condensed tannin content ranged from 25.49±0.53 to 3.35±1.85 mg/g dw and the total antioxidant capacity ranged from 0.18±0.012 to 0.010±0.004 mg AAE/g dw. Furthermore, a principal component analysis was conducted to assess the relationship between the different parameters. The analysis revealed a strong correlation between the total phenolic content, total flavonoid content and hydrolysable tannin content with the total antioxidant capacity. This suggests that these compounds contribute significantly to the antioxidant capacity of Ajuga iva. Overall, the findings of this study demonstrate that Ajuga iva contains substantial amounts of bioactive compounds and possesses a noteworthy antioxidant capacity. These results contribute to the understanding of the chemical composition and potential health benefits of Ajuga iva.
Quantum Mechanics as a Fourier Representation of a Relativistic Quantum Particle
Authors: Stefanescu Eliade
Published: January 2024

The starting point of this research is a representation of a quantum particle according to the Schrodinger equation of the conventional quantum mechanics. In this representation, a quantum particle is described by a wave packet in the coordinate space and the conjugated wave packet in the momentum space. The problem is that while in the coordinate space the group velocity is in agreement with one of the Hamilton equations, the group velocity in the momentum space is in contradiction with the other Hamilton equation - a minus sign is missing. Group velocities in agreement with the Hamilton equations are obtained only when in the time dependent phase of a quantum particle wave packet, instead of the Hamiltonian coming from the conventional Schrodinger equation, the Lagrangian is considered. This suggests us to consider the relativistic Lagrangian in the time dependent phase. In this way, the conventional relativistic principle of invariance of the time-space interval gets the more physically understandable form of the invariance of the time dependent phase of a quantum particle - the time dependent phase of a quantum particle is the same in any system of coordinates. Based on the relativistic time dependent phase invariance of a quantum particle, from the group velocities of this particle the relativistic kinematics and dynamics are obtained. The interaction with an electromagnetic field is described by a modification of the time dependent phase with a scalar potential conjugated to time and a vector potential conjugated to the space coordinates. In this paper, we find that, according to the formalism of the general relativity, any matter element in a field of forces is accelerated only perpendicularly to its velocity. This means that the matter propagation of a quantum particle can be conceived in planes perpendicular to velocity, while the mater distribution can be considered in a Fourier representation - quantum waves. We study the quantum particle dynamics in gravitational waves and derive the graviton spin. We consider a quantum particle in electromagnetic field and obtain a Schrödinger-Dirac-type equation, with additional terms describing the velocity dependence of the particle dynamics.

Authors: Zwerling Charles S
Published: January 2024

A prospective study for traumatic optic neuropathy has been performed to review and revise management proto col for active military personnel and veterans who have sustained either traumatic brain injury (TBI) or mild traumatic brain injury (mTBI aka head concussions). A new protocol for visual field testing to include both kinetic and static testing was utilized to uncover occult cases of traumatic optic neuropathy (TON) either from traumatic brain injury or from mild head concussions as well as confirm suspected cases of TBI and/or mTBI. Furthermore, we have identified that military parachute jumpers (paratroopers) represent a high-risk group for undiagnosed mild TBI and traumatic optic neuropathy. We have urged that collaboration and development of safer helmet design would help reduce and maybe prevent further TBI, mTBI, and traumatic optic neuropathy for the military personnel.
Development Delays, Illegal Immigration and the Informal Sector in French Guiana
Authors: Aladji Moustapha
Published: January 2024

The arrival of a population on a territory brings a potential source of additional work that overall allows the host country to increase its growth as shown by Chojnicki and Ragot (2012) in their study. However, the France has the particularity of being present on different continents and thus holding territories with great disparity. Through this article, we want to focus on immigration in French Guiana, looking for explanatory factors for the reasons for immigration to this territory. At the same time, we are asked about the contributions of this immigration to know if it represents an asset or a constraint for the development of the territory. The answer is obviously not binary, which gives more interest and complexity to the question. Thus, we were able to carry out a first theoretical analysis in order to grasp the most relevant elements to be studied in order to set up the empirical analysis. Then, we chose a Probit model that we then confronted with the Hosmer-Lemeshow test. The theoretical analysis allowed us to highlight various elements of informal integration (housing, working conditions) that also promote a form of precariousness. Empirical analysis, she rather highlighted the correlated factors that support this immigration rate. Finally, we observed the case of the Hmong population settled in French Guiana for several decades, which represent a relatively successful example of immigration with a positive economic impact.

Published: January 2024

With extremely high BOD, COD, and other harmful organic and inorganic elements, spent wash is among the most complicated and time-consuming wastewaters. Because of the presence of several water soluble, colouring chemicals and recalcitrant primarily melanoidins, distillery effluent maintains a very dark brown hue even after anaerobic treatment. The aim of the study includes standardising several criteria for the extraction of melanoidin pigment as well as the isolation and identification of bacteria from natural sources. Methods: Pseudomonas putida, a melanoidin-decolorizing bacterium, was isolated in a lab setting using the serial dilution technique, and the culture conditions were improved at different incubation temperatures, times, pH levels, carbon sources, and nitrogen sources. On 120 hours, or the fifth day of culture, the optimal decolorization (86.05%) of melanoidins were accomplished at pH 5 and 37 °C. Based on the results of optimising the culture settings, it was discovered that the chosen bacterial strain needs 1.5 gm of extra carbon (Dextrose) and 1.5 gm of supplementary nitrogen (Ammonium sulphate) in order to decolorize. After bacterial treatment, dextrose and ammonium sulphate are supplied to the effluent, which is both cost- and environmentally-friendly. By using bacterial strain Pseudomonas putida, this method of biological treatment successfully decolorizes melanoidin from distillery effluent.

Authors: Theja Pindi Charan , Gundala Prasada Babu , Chinthala Paramageetham
Published: January 2024

Small subunit (16S rRNA) gene-based surveys were employed to investigate the phylogenetic diversity within the unique muscovite ecosystem. This approach unveiled a broader scope of diversity compared to traditional culture-based methods. Notably, yanobacterial diversity remained remarkably stable at the phylum level, underscoring the ecological resilience of Muscovite. In Muscovite, the phylum Cyanobacteria accounted for 0.5983% of the microbial population. Within this phylum, classes including ML635J-21, Nostocophycideae, Synechococcophycideae, and Oscillatoriophycideae were identified, alongside an unclassified category. Notably, 517 cyanobacterial clones were detected, signifying their presence in the microbial community. Intriguingly, a substantial proportion (0.2616%) of cyanobacterial clones fell into unclassified orders, indicating potential unidentified microbial lineages within this group. Among the identified classes, ML635J-21 exhibited the highest abundance, with 225 clones. However, all classes within Cyanobacteria were underrepresented. The presence of an unclassified category further highlighted the need for comprehensive taxonomic characterization within this environment. These results emphasize the diverse and potentially novel cyanobacterial communities thriving in the Muscovite ecosystem, prompting further exploration to uncover their ecological roles and contributions.

Published: January 2024

High production and good quality are always the principal goals for agriculturally important crop. Oyster mushroom is the choicest edible species cultivated in various region of the world. The yield performance improvement was carried out through hyphal anastomosis of four oyster mushroom viz., Pleurotus sajor-caju (Ps), P. citrinopleatus (Pc), P. florida (Pf) and Hypsizygus ulmaius (Hu) with each other and by physical mutation that comprised the exposure of mushroom culture to UV radiation and by chemical mutation by Ethyl Methyl Sulfonate (EMS). Date of spawning, days required for spawn run, days required for pinhead initiation, total yield/ bed, biological efficiency was evaluated. Out of six crosses, the cross between Ps and Pc recorded the maximum biological efficiency. In respect of effect of UV radiation maximum biological efficiency (98.27%) was observed in Ps when its mycelium was exposed to UV radiation for a period of 30 minutes. EMS had negative effect on mycelial growth of Pc and Ps whereas it had positive effect on mycelial growth of Pf at three concentrations (0.003, 0.004 and 0.005%). The results suggested that the exposure to UV radiation for 30, 4, 5, and 10 minutes respectively was effective in enhancing the biological efficiency of the mushrooms under study. EMS favored mycelial growth of Hu except at a concentration of 0.005 per cent.

Ablutions in public toilets present many risks to the health of populations. Thus, data were collected to assess the quality of these waters. To do this, electrochemical and spectrophotometric methods were determined for the analysis of classical physico-chemical parameters. The bacteriological parameters were determined by the membrane filtration technique. Based on the results obtained, the parameters involved are residual chlorine (0.09 mg/L), turbidity (1.88 UNT), E. coli (3 CFU/100 ml), total coliforms (53 CFU/100 ml). Therefore, the low degree of disinfection is characteristic of these public latrine ablution waters. This leads to the emergence of Escherichia coli, which pose enormous risks to population health. As a palliative solution, sanitary surveillance of these waters used for ablution is therefore necessary to preserve the health of populations.

Soil and root samples were randomly collected from the rhizosphere of Calotropis procera (Calotropis) growing in two wild locations of Makueni and Tharaka-Nithi Counties, Kenya. The root samples were assessed for arbuscular mycorrhizal fungi (AMF) colonization. The soil samples were analyzed for physic-chemical properties and screened for the presence, abundance and diversity of AMF. The AMF inoculum potentials of the soils were determined using the bioassay test. The results depicted significant variations between the sites in soil pH, % sand, % clay, % silt, available P and Mg concentrations. These soil parameters had, generally, marked effects on AMF colonization, spore numbers and genus richness from the correlation analysis results. The Makueni site registered slightly higher mean spore densities than the Tharaka-Nithi site. Tharaka-Nithi site recorded relatively higher genus richness and AMF root colonization percentage than the Makuenisite. Overall, 6 AMF genera were identified in the soils, of which 4 (Dentiscutata, Scutellospora, Glomus and Acaulospora) were discovered in both sites while 2 (Gigaspora and Rhizaphagous) occurred in Tharaka-Nithi site only. Glomus was comparatively dominant and ubiquitous in both sites. The genera Dentiscutata, Scutellospora, Glomus and Acaulospora could possibly be tested for suitability as mycorrhizal inoculants of Calotropis seedlings in the dry lands of Kenya.

Published: January 2024

Using the Mahalanobis D2 statistic, the genetic divergence among 32 genotypes of brinjal for 23 characters was examined. On the basis of the relative magnitude of the D2 values, the genotypes were divided into eight clusters. The largest of the eight clusters, cluster I, had 18 genotypes. It was followed by cluster V (five), cluster III (four), and the remaining clusters, which each had a single genotype. The largest intra-cluster distance (8277.51) was in cluster V, which was followed by cluster I (4488.09) and cluster III (3908.52). The remaining clusters had very small intra-cluster distances. The highest inter-cluster D2 value (23195.60) was found between clusters III and VI, while the lowest value (5777.13) was found between clusters IV and VI. In cluster VI, the mean value for almost all of the characteristics was greatest. Maximum genetic divergence was caused by traits including fruit weight, days to first harvest, number of fruits per cluster, and percentage of fruit set in pseudo short-styled flowers.

At Dr. YSR Horticultural University in Venkataramannagudem, thirty-two brinjal genotypes were examined during the Rabi 2022–23 growing season in terms of character association and path analysis. The reciprocal relationship between two plant characteristics is evaluated by correlation coefficient analysis, which also identifies the yield components for selection in order to increase yield. According to the results of the current study, fruit yield per plant significantly and favorably correlated with the number of fruits per plant, the percentage of fruits set in long styled flowers, the percentage of fruits set in medium styled flowers, the weight of the fruits, and the duration of the harvest time. Direct selection based on these characteristics could improve fruit yield. In addition, it was found that genotypic correlations were significantly higher than phenotypic correlations, pointing to a strong inborn association between these features. Through path coefficient analysis, the direct and indirect effects of various component attributes on yield were found. The number of fruits per plant, the proportion of fruits set in long-styled flowers, the proportion of fruits set in medium-styled flowers, the length, diameter, and weight of the fruits, as well as the duration of the harvest time, all exhibited positive correlations and direct effects on the number of fruits per plant.

Nutritional needs in hatcheries are very important to support the growth and health of larvae. This study aims to determine the growth response and performance of tiger shrimp post larvae given artemia instars that have a yolk sacand artemia that do not have a yolk sac. The test animals used were stadia Pl-1 of tiger shrimp post larvae, rearing containers of fiber tanks, volume of 1,000 liters, 12 units, stocking density of 30 individuals/liter. Using a completely randomized design with 3 treatments and 4 replications, namely (A) the use of instar artemia which still hada yolk sac, (B) artemia which did not have a yolk sac and (C) 50% of treatment A and 50% of treatment B respectively. The results of this study were weight growth in treatment A 0.00258 g and treatment B 0.00232 g and treatment C 0.002280. The relative growth rate in treatment A was 45.4%, B 40.0% and C 39.2%. Survival rates ranged from 67.4%-62.2% and there was no significant difference. Morphological score values ranged from 91.8-89.0. Vitality performance of post larvae through immersion test in 200 ppm formalin for 30 minutes which treatment A 78.67%, B 73.33% and C 75.33% while through freshwater immersion test for 15 minutes that treatment A 23%, B 13.33% and C 20.0%. In conclusion, the relative growth rate of post larvae of tiger shrimp given artemia which has a yolk sac(A) is better (13.5%) than artemia which does not have a yolk sac(B) or from a combination of both (C) which is 16.0%. The survival rate of treatment A was better (7.6%) than treatment B and (3.7%) of treatment C. Morphological performance was not significantly different between treatments A, B and C. Vitality performance with the formalin test was relatively similar and not significantly different, but through freshwater immersion treatment A was much better (120%) and significantly different than treatment B, and better (47.7%) than treatment C.
