This study is delineated to examine the role of social factors in the decision-making process of individual investors. This study is based on quantitative research approach and utilized a 5-points Likert type closed-end structured questionnaire survey to collect the data from 269 individuals, invested in the firms listed at Nepal Stock Exchange (NEPSE). This study utilized reliability analysis, descriptive statistics, Pearson correlation coefficient and ordinary least square (OLS) method. Evidence indicates that herding, social interaction and media effect shows the positive influences on equity investment decision process of the investors. Finally, this study justified that social biases play the significant role for equity investment decisions of the individual investors through excessive follow the humor of the market place, over or under reaction of the information about securities, follow the suggestions and recommendations of peers, friends, family members and neighbors along with highly depend upon news, social medias and information of so-called experts of capital market that leads to investment mistakes. Hence, investors should strongly follow the proper information about stock and market, utilize their own knowledge about information processing and analysis, and try to reduce the biases while making decisions through information analysis and processing that may downsize the irrational decisions.","PeriodicalId":404599,"journal":{"name":"BMC Journal of Scientific Research","volume":"41 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138945643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Further, the model has been used to compute the activities of the component Sn in the ternary Sn-Sb-Bi system at 900K at the three cross-sections, i.e., Sb:Bi = 1:3, 1:1, and 3:1. The theoretical data have been analyzed with the corresponding experimental data accessible in the literature. An acceptable concurrence has been obtained, with some inconsistencies. The activities of the ternary alloys along the three cross-sections, i.e., Sb:Bi = 1:3, 1:1, and 3:1, show that the deviations change from positive to negative with increasing Sb content. The results confirm that MIVM is a good model for estimating the thermodynamic properties of binary and ternary systems.","PeriodicalId":404599,"journal":{"name":"BMC Journal of Scientific Research","volume":"35 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138946822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to assess the QoL of elderly people in the Chitwan district, Nepal. An analytical cross-sectional study design was employed to evaluate the Quality of Life (QoL) among the elderly residing in the 17 wards encompassing all municipalities and the metropolitan area. The sampling method employed was Probability Proportionate to Size (PPS), which facilitated the selection of 26 respondents from each of the chosen wards. In total, 442 elderly individuals were recruited from the community and surveyed using the WHOQoL-brief questionnaire. Descriptive and inferential statistics were used to analyze data in SPSS 20. Most of the elderly mentioned neutral status in both overall QoL (71%) and satisfied with their health status (48.4%). Elderly aged 60-69 years had higher QoL scores in the physical (p<0.007) and psychological (p<0.014) domains compared to other age groups. There was statistically significant association of physical domain with age group, marital status, religion, and presence of chronic illness. The psychological domain was associated with age group, education, religion, and presence of chronic illness. The social domain was associated with marital status, type of family, education, ethnicity, and presence of chronic illness. The environmental health domain was associated with sources of family income, marital status, education, different living arrangements, religion, ethnicity, and presence of chronic illness. All QoL domains showed a positive correlation (p<0.01) with each other as well as with the overall health and quality of life of elderly people. The overall health status and QoL of elderly people was neutral. As increasing the age of the elderly, almost domains of quality of life were declining. Living arrangement with family was associated with the environmental health domain. The absence of chronic illness was associated with all domains of the quality of life of the elderly.","PeriodicalId":404599,"journal":{"name":"BMC Journal of Scientific Research","volume":"50 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138946152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The indigenous people around the world have established their own local knowledge on plant utility, management and conservation since time immemorial. It has attracted much attention in recent years. In Devchuli-13 (Daldale) area, local people depend on fiber yielding plants in their daily life because most of them do farming and rearing animals. These plants are mostly used while collecting fodder and dried tree branches from the near forest or pasture lands. The total of 52 fiber yielding plants species belonging to 45 genera and 24 families has been documented among them. Poaceae family with 17 species is largest. Large number of plant species found are herbs (about 39%) are herbs followed by trees, shrubs and climbers. Among these plant 21 species are mostly used by the local people. Most of these plants are used for making ropes baskets, mats followed by making brooms. The most common parts used are whole plant of herbs, stem/bark of trees (xylem, phloem, cortical fibers) while roots are very rarely used. Large number of highly valuable plants are reported which can improve the economic condition of people or creating the scope for small businesses. Documentation of ethnobotanical knowledge of traditional practices is gradually going to disappear from the elder to younger generations. So, proper documentation of fiber yielding plants with their economic value is very important. Addressing these set of skill is very important to eradicate the immerging problem of unemployment.","PeriodicalId":404599,"journal":{"name":"BMC Journal of Scientific Research","volume":"6 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138944258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So, this study analyses the relationship between gender and knowledge of a reservation system using data from the Social Inclusion Survey conducted by Nepal Government in 2020. The author used SPSS software and conducted parametric and non-parametric tests, including Chi-square and binary logistic regression. Through this analysis, it is found that there is a close relationship between gender and knowledge of the reservation system because the p-value of the Chi-Square test is 0.00. Nevertheless, the logistic regression result proved that people have moderate knowledge of the reservation system and suggested that education and training initiatives are needed to improve people's awareness of the reservation system.","PeriodicalId":404599,"journal":{"name":"BMC Journal of Scientific Research","volume":"42 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138945630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chromium (Cr) belongs to the d-block element in the modern periodic table. Chromium has a wide range of oxidation states ranging from -2 to +6. Chromium mostly exists in the environment as trivalent (Cr3+) and hexavalent (Cr6+) states. Both trivalent and hexavalent states of chromiums are derived from the industrial effluents. Ingestion, dermal contact, and inhalation are the most common routes through which chromium enters the human body. Ion chromatography inductively coupled plasmamass spectrometry (IC-ICP-MS) is mostly used for the speciation analysis of metals. Hexavalent chromium is highly soluble and mobile in alkaline and slightly acidic soils, whereas trivalent chromium is less soluble, adheres to the coarse material on the soil, and precipitates as Cr(III) hydroxide. Hexavalent chromium is more detrimental as compared to trivalent chromium. The detrimental effects of chromium are bronchial asthma, lung cancer, nasal ulcers, skin allergies, carcinogenicity, and genotoxicity. To protect from these adverse effects, WHO has suggested a provisional guideline value of chromium as 0.05 mg/L until further information is available and revalued.","PeriodicalId":404599,"journal":{"name":"BMC Journal of Scientific Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124793415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
