This study provides a comprehensive analysis of the financial markets in the 21'st century; focusing on the G7 countries: Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States. The justification for this research originates from the significant role these markets plays in the global economy and the need to understand their complexities in relation to risk, uncertainty, and economic growth. The primary objective is to empiricaly investigate the dynamics and correlations of these aspects within the financial markets of the countries selected in this study. The study is based on secondary data spanning 12 years, from 2010 to 2021, covering all 7 countries, and making it a panel data analysis. Methodologically, the research employs various econometric models and techniques, including Ordinary Least Squares, OLS Robust, and fixed and random effects models. The empirical results suggest that the fixed effects model is the most suitable for this study, as confirmed by the Hausman test. According to this model, a 1% increase in stock market capitalization relative to GDP positively impacts GDP growth by 0.06. Furthermore, stock market value trades were found to have a positive correlation with economic growth. In contrast, stock price volatility and pension fund assets negatively impact economic growth. Notably, these findings diverge from some previous studies in the field. In conclusion, the research provides valuable insights into the relationship between financial markets and economic indicators in the G7 countries, thereby offering policy-makers a more nuanced understanding of how to foster economic growth while mitigating risks.
本研究报告对 21 世纪的金融市场进行了全面分析,重点关注 G7 国家:加拿大、法国、德国、意大利、日本、英国和美国。开展这项研究的理由是,这些市场在全球经济中发挥着重要作用,需要了解它们与风险、不确定性和经济增长之间的复杂关系。本研究的主要目的是对所选国家金融市场中这些方面的动态和相关性进行实证调查。本研究基于从 2010 年到 2021 年 12 年的二手数据,涵盖所有 7 个国家,是一项面板数据分析。在方法上,研究采用了多种计量经济学模型和技术,包括普通最小二乘法、OLS Robust、固定效应和随机效应模型。实证结果表明,固定效应模型最适合本研究,这一点已被豪斯曼检验所证实。根据该模型,股票市值相对于 GDP 每增加 1%,会对 GDP 增长产生 0.06 的正向影响。此外,研究还发现股票市场价值交易与经济增长呈正相关。相比之下,股票价格波动和养老基金资产对经济增长产生负面影响。值得注意的是,这些发现与该领域以往的一些研究有所不同。总之,这项研究为了解 G7 国家金融市场与经济指标之间的关系提供了宝贵的见解,从而使政策制定者对如何在促进经济增长的同时降低风险有了更细致的了解。

This study was designed to investigate the effect of hypercholesterolemia on the reproductive performance of premature male rats and to evaluate the influence of alpha lipoic acid (ALA) in conserving their fecundity. Sixty rats were randomly assigned to one of three groups. The control group (CG n=20 rats), cholesterol feeding group 1 (CFG1 n=20 rats) were fed 1.5% cholesterol with diet for one month, and cholesterol feeding group 2 (CFG2 n= 20 rats) were fed 1.5% cholesterol with diet + ALA 100 mg/kg body weight supplied by water for one month. The results revealed that compared to CG and CFG2, CFG1's body weight increased significantly. After consuming cholesterol for one month, CFG1's lipid profile revealed a substantial rise in blood cholesterol and triglycerides when compared to CG and the group that consumed ALA CFG2. In comparison to CGF1 and CG, the results of the sperm parameters in CGF2 demonstrated a large rise in sperm count with sperm live percentage and a considerable decrease in sperm abnormality %. Rats from CFG1 had significantly lower serum testosterone levels than rats from CFG2 and CG, according to the hormonal profile. We conclude that the significance of alpha lipoic acid (ALA) in preserving fertility ALA is a strong antioxidant that may preserve the parameters of the sperm of hyperlipidemic preterm rats, which may improve the capacity of hyperlipidemic rats to conceive.
本研究旨在调查高胆固醇血症对早产雄性大鼠生殖能力的影响,并评估α-硫辛酸(ALA)对保护其生育能力的影响。60 只大鼠被随机分配到三组中的一组。对照组(CG n=20 只大鼠)、胆固醇喂养 1 组(CFG1 n=20 只大鼠)在饮食中喂养 1.5% 的胆固醇,为期一个月;胆固醇喂养 2 组(CFG2 n=20 只大鼠)在饮食中喂养 1.5% 的胆固醇 + 100 毫克/千克体重的 ALA 水,为期一个月。结果显示,与CG和CFG2相比,CFG1的体重明显增加。在摄入胆固醇一个月后,与 CG 和摄入 ALA 的 CFG2 组相比,CFG1 的血脂谱显示血液中胆固醇和甘油三酯大幅上升。与 CGF1 和 CG 相比,CGF2 的精子参数结果表明,精子数量和精子活率大幅上升,精子畸形率大幅下降。从激素谱来看,CFG1 大鼠的血清睾酮水平明显低于 CFG2 和 CG 大鼠。我们的结论是,α-硫辛酸(ALA)在保护生育能力方面具有重要意义 ALA是一种强抗氧化剂,可保护高脂血症早产大鼠的精子参数,从而提高高脂血症大鼠的受孕能力。

This study investigates the access to finance among Micro, Small, and Medium Entities (MSME) in Kosovo, providing an understanding of the financial landscape of this important sector. Utilizing a quantitative research design, the study administered a structured questionnaire to a representative sample of 250 MSME in Kosovo, encompassing a variety of industries and sizes.  The questionnaire measured the types of financing used, perceived barriers to accessing finance, and the impacts of financial constraints on the business.Data analysis included descriptive statistics, inferential statistics, and regression analysis. Findings suggest a reliance on internal funds among most MSMEs, with high-interest rates and stringent collateral requirements identified as major barriers to accessing external finance.  Moreover, firm size and years of operation appeared to positively influence access to finance. The study concludes with recommendations for regulatory reforms, financial sector development, and capacity building to ease these barriers and enhance MSME growth and competitiveness.Further research is encouraged to probe the effectiveness of different interventions and delve deeper into the experiences of MSMEs in navigating their financial constraints.

In order to keep up with the ever-increasing need for energy, the use of fossil fuels has no choice but to keep rising in tandem with the world's population, which is rapidly industrialising, urbanising, and expanding economically. Finding a suitable and environmentally friendly alternative to fossil fuels will become necessary if emissions from the use of fossil fuels continue unabated. Because of its renewable, non-toxic, and environmentally friendly character, biodiesel is an appropriate alternative solution that may be used in diesel engines. In the current investigation, the compression ratio of CI (Compression Ignition) engines was varied from 17 to 20 in an effort to find the optimum combination of performance, combustion, and emission characteristics for IC engines. When compared to the same blend at CR (Compression Ratio) 18, the BTE (Brake Thermal Efficiency) levels of KME20 (Kapok Methyl ester 20) at CR 19 were 5.6% higher. When compared to greater CR, the KME20 blend's emission values for both UBHC (Unburnt Hydro Carbons) and CO (Carbon monoxide) are higher than their respective values. When the compression ratio was reduced to 19, the emissions from the blend KME20 were 9.1% and 9.6% lower than when the same fuel was used at the standard compression ratio. It's possible that this is because the oxidation process of the hydrocarbons is more efficient, in addition to the fact that the temperature in the cylinder is high enough to promote full combustion.
为了满足日益增长的能源需求,化石燃料的使用量只能随着世界人口的迅速工业化、城市化和经济扩张而不断增加。如果使用化石燃料所产生的排放继续有增无减,那么寻找一种合适且环保的化石燃料替代品就变得十分必要。生物柴油具有可再生、无毒和环保的特点,是一种可用于柴油发动机的合适替代解决方案。在目前的调查中,CI(压燃)发动机的压缩比在 17 到 20 之间变化,以找到 IC 发动机性能、燃烧和排放特性的最佳组合。与压缩比为 18 的相同混合燃料相比,压缩比为 19 的 KME20(木棉甲酯 20)的 BTE(制动热效率)水平高出 5.6%。与更大的压缩比相比,KME20 混合燃料的 UBHC(未燃烧碳氢化合物)和 CO(一氧化碳)排放值均高于各自的排放值。当压缩比降低到 19 时,KME20 混合燃料的排放量比以标准压缩比使用相同燃料时分别低 9.1% 和 9.6%。这可能是因为碳氢化合物的氧化过程更加有效,此外气缸内的温度也足够高,从而促进了充分燃烧。

Finding a suitable and environmentally friendly alternative to fossil fuels will become necessary if emissions from the use of fossil fuels continue unabated. Because of its renewable, non-toxic, and environmentally friendly character, biodiesel is an appropriate alternative solution that may be used in diesel engines. In the current investigation, the compression ratio of CI (Compression Ignition) engines was varied from 17 to 20 in an effort to find the optimum combination of performance, combustion, and emission characteristics for IC engines. When compared to the same blend at CR (Compression Ratio) 18, the BTE (Brake Thermal Efficiency) levels of KME20 (Kapok Methyl ester 20) at CR 19 were 5.6% higher. When compared to greater CR, the KME20 blend's emission values for both UBHC (Unburnt Hydro Carbons) and CO (Carbon monoxide) are higher than their respective values. When the compression ratio was reduced to 19, the emissions from the blend KME20 were 9.1% and 9.6% lower than when the same fuel was used at the standard compression ratio. It's possible that this is because the oxidation process of the hydrocarbons is more efficient, in addition to the fact that the temperature in the cylinder is high enough to promote full combustion.","PeriodicalId":218411,"journal":{"name":"Multidisciplinary Science Journal","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139277900","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}

Wheat crop classification and prediction are important tasks for the optimization of crop yield and resource utilization. In this study, we propose an Artificial Neural Network (ANN) model integrated with Genetic Algorithm (GA) to predict and classify the wheat crop images of different ages. The dataset of 19,300 images was used, and the model was trained and tested using various performance evaluation metrics. The results show that the proposed ANN+GA model achieved the highest accuracy of 99.29% during the training phase and 98.65% during the testing phase. The model was also compared with other state-of-the-art machine learning models, and the proposed model was found to be superior in terms of accuracy, specificity, sensitivity, precision, and F-measure. The graph of training and testing accurateness and loss values in contradiction ofindividual epoch demonstrating the speediness of model convergence. Our proposed model is feasible and robust, giving better classification and crop forecast outcomes for numerous wheat crop age groups with least resource necessities. These findings could be useful for farmers and agricultural researchers in improving crop yield and resource management.

TThe pollen loads from 137 honeycombs of Apis dorsata (Rock Bee) were examined. These honeycombs were collected from the Chimur forest area (Allizanza, Jamni Borgaon of Chandrapur District of Maharashtra State) during the period between May 13 and May 23, 2013. It was determined that 25 loads (18.24%) were unifloral, 23 loads (16.78%) were biforal, and 89 loads (64.96%) were multifloral. Unifloral pollen loads contained pollen from Terminalia sp. In fact, Terminalia sp. pollen was present in 111 loads (81.02%) of the total pollen samples examined. This study establishes that Terminalia sp. (Combretaceae) constitutes the primary source of pollen for honey bees during the summer, with Mangifera indica (Anacardeaceae), Citrus sp. (Rutaceae), Blumea sp. (Asteraceae), and Delonix regia (Caesalpineaceae) following as significant sources.

Rebon shrimp is a local food in Bagan Serdang Village that has a very high nutritional content. One hundred grams of dried rebon contains 2.306 mg of calcium or equal to 16 times the calcium of 100 grams of cow's milk. Calcium takes part in preventing demineralization by keeping the pH neutral. The aim of this study was to evaluate the effectiveness of rebon shrimp crackers to increase salivary calcium ion among elementary school children. This type of research is an experimental study with pre and post test group design to obtain the average calcium ions in saliva before and one month after consuming rebon shrimp crackers. The minimum sample size were 40 samples, which 20 samples were included in the intervention group who were given each day one pack each for 30 days during school breaks and supervised by teachers, while 20 samples were included in the control group and were not given crackers. Saliva sampling was carried out using the unstimulated method. The concentration of salivary calcium ions before and after given the intervention was measured using paired t test and to analyze the difference in the concentration of salivary calcium ions between the two groups using an unpaired t test. There was a significant difference in the concentration of salivary calcium ions between the group given rebon shrimp crackers and the group that was not given rebon shrimp crackers (p=0.034). There was a significant increase in the concentration of salivary calcium ions before and after being given rebon shrimp crackers (p=0.000), whereas in the untreated group that was not given crackers there was no significant increase (p=0.496). It can be concluded that the risk of dental caries can be reduced by consuming local food ingredients that are high in calcium and minerals.
雷本虾是蒲甘瑟当村的一种当地食品,营养成分非常高。100 克干雷波虾含有 2.306 毫克钙,相当于 100 克牛奶钙含量的 16 倍。钙可通过保持 pH 值中性来防止脱矿。本研究的目的是评估干果虾仁饼干增加小学生唾液钙离子的效果。这类研究是一项实验性研究,采用前测和后测的分组设计,以获得食用瑞邦虾片前和食用瑞邦虾片一个月后唾液中钙离子的平均值。最小样本量为 40 个样本,其中 20 个样本被纳入干预组,干预组在老师的监督下,利用课余时间每天给孩子们吃一包虾仁饼干,持续 30 天;20 个样本被纳入对照组,对照组不给孩子们吃虾仁饼干。唾液采样采用非刺激法。采用配对 t 检验测量干预前后唾液钙离子的浓度,并采用非配对 t 检验分析两组之间唾液钙离子浓度的差异。结果表明,服用瑞本虾片组和未服用瑞本虾片组的唾液钙离子浓度有明显差异(P=0.034)。在食用罗邦虾片前后,唾液中钙离子的浓度明显增加(p=0.000),而未食用罗邦虾片组的唾液中钙离子的浓度没有明显增加(p=0.496)。由此可以得出结论,食用含钙和矿物质较多的当地食材可以降低患龋齿的风险。
