Erosion processes, triggered by water, occur and propagate on sloping surfaces and have a significant negative impact on the soil quality and vegetation, as well as cause a change of the topographic surface. In the long term, they can lead to an increase in sediment transport, siltation of dams, and higher flood hazard. The development of water erosion reflects on the slope profile and the specific landforms like rills and gullies. In this regard, the geomorphological features of the areas can be considered indicators of the spatial distribution of erosion and accumulation. The sediment properties give information about the conditions of the transport and the intensity of the hydrogeomorphic processes. The current study aims to analyse the short-term changes in erosion and deposition by application of morphometry and grain size analysis. Topographic wetness index (TWI) and cross-section profiles of two small gullies were analysed based on high-resolution digital terrain models (DTMs), generated from unmanned aerial system (UAS) data. Remote sensing was combined with field geomorphological research and sediment sampling. The results of the research show about average 2 cm change in erosion and deposition for the period October 2021 – November 2022. Despite TWI and cross-section profiles depending on the DTMs resolution, they are reliable indicators for erosion and deposition. The grain size analysis supports the morphometric analysis. Coarse to very fine sands are predominant in most cases of sediment sampling. The sorting coefficient shows very poorly to moderately sorted deposits which indicates transport in a more dynamic environment and temporary flow.
由水引发的侵蚀过程在坡面上发生并传播,对土壤质量和植被产生重大负面影响,并导致地形表面的变化。从长远来看,它们可能导致泥沙运输增加、大坝淤积和更高的洪水风险。水土流失的发展反映在坡面剖面和细沟、冲沟等特定地貌上。在这方面,这些地区的地貌特征可以被视为侵蚀和堆积空间分布的指标。沉积物的性质提供了有关迁移条件和水文地貌过程强度的信息。本研究旨在通过形态计量学和粒度分析来分析侵蚀和沉积的短期变化。基于无人机数据生成的高分辨率数字地形模型,分析了两条小冲沟的地形湿度指数(TWI)和横截面轮廓。遥感与实地地貌研究和沉积物取样相结合。研究结果显示,2021年10月至2022年11月期间,侵蚀和沉积平均变化约2厘米。尽管TWI和横截面剖面取决于DTMs的分辨率,但它们是侵蚀和沉积的可靠指标。粒度分析支持形态计量分析。在大多数沉积物取样情况下,粗砂至极细砂占主导地位。分选系数显示出分选非常差到中等的沉积物,这表明在更动态的环境和暂时的流动中运输。

Bangladesh’s deltaic geography makes it highly subject to natural disasters, with the southwest region being especially vulnerable to cyclones, storm surges, waterlogging during the monsoon, and soil salinity during the dry season. Despite being primarily an agricultural country, frequent natural disasters have severely impacted crop production and biodiversity, making it difficult for small coastal farmers to earn a livelihood. This study sought to identify the various income-generating activities and effective strategies that could help the waterlogged community become more resilient to the challenges posed by climate change. A mixed method, including a household survey, field visit, in-depth interview, and key informant interview, was used to collect data based on the purposive sampling technique. The collected quantitative and qualitative data were analyzed using percentage measures and narrative processes, respectively, and interpreted in the socio-cultural context to give a specific form and basis to the study. The study revealed that marginal farmers in Malopara village are particularly vulnerable to biodiversity losses that threaten their lives and livelihoods. To address these challenges, the study also found multiple income-generating activities as a way of community-based adaptation. This approach would help reduce food insecurity and provide alternative sources of income for small farmers, who are most affected by the changing climate.
孟加拉国的三角洲地理使其极易遭受自然灾害,西南地区尤其容易受到气旋、风暴潮、季风期间的内涝和旱季土壤盐度的影响。尽管主要是一个农业国家,但频繁的自然灾害严重影响了作物生产和生物多样性,使沿海小农户难以谋生。这项研究试图确定各种创收活动和有效的战略,这些活动和战略可以帮助被水淹没的社区更能应对气候变化带来的挑战。采用混合方法,包括家庭调查、实地考察、深入访谈和关键信息员访谈,基于目的性抽样技术收集数据。分别使用百分比测量和叙述过程对收集的定量和定性数据进行分析,并在社会文化背景下进行解释,为研究提供特定的形式和基础。研究表明,Malopara村的边缘农民特别容易受到生物多样性损失的影响,这威胁到他们的生命和生计。为了应对这些挑战,该研究还发现,多种创收活动是一种基于社区的适应方式。这种方法将有助于减少粮食不安全,并为受气候变化影响最大的小农户提供替代收入来源。

In this paper, carbon nanotubes (CNT) are synthesized using the microwave oven method, which offers several advantages, including a simple, quick, inexpensive, and solvent-free growing method. To produce CNT, a mixture of graphite and ferrocene catalysts had to be flattened inside a microwave oven for five seconds at room temperature. CNT was produced using various ratios of graphite and ferrocene, and analyses indicated that a 70:30 graphite/ferrocene ratio produced better nanocrystalline CNT. To optimize CNT properties, five processes of purification were used to dispose of impurities like metal particles and support material from the as-produced carbon nanotubes. Raman spectroscopy, field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR) was used to characterize the CNTs both after and before purification. After acid treatment and centrifugation, the amount of amorphous carbon and iron particles significantly decreased. Additionally, following the purification process, the ID/IG decreased by 0.14 and the I2D/ID increased by 0.55 for the purified CNTs. Furthermore, the FTIR spectra of the untreated and functionalized CNTs confirm the presence of carboxyl groups on pure CNTs and -OH moieties in sorbed water.
本文采用微波炉法合成了碳纳米管,该方法具有简单、快速、廉价、无溶剂等优点。为了生产碳纳米管,石墨和二茂铁催化剂的混合物必须在室温下在微波炉内压平5秒钟。使用不同比例的石墨和二茂铁制备CNT,分析表明,70:30的石墨/二茂铁比例制备出更好的纳米晶CNT。为了优化CNT的性能,使用了五种纯化工艺来处理来自所生产的碳纳米管的杂质,如金属颗粒和载体材料。使用拉曼光谱、场发射扫描电子显微镜(FESEM)、能量色散X射线光谱(EDX)、X射线衍射(XRD)和傅里叶变换红外光谱(FTIR)对纯化前后的CNT进行表征。经过酸处理和离心后,无定形碳和铁颗粒的量显著减少。此外,在纯化过程之后,纯化的CNT的ID/IG降低了0.14,I2D/ID增加了0.55。此外,未处理和官能化的CNT的FTIR光谱证实了在吸附水中纯CNT和-OH部分上存在羧基。

This study aims to identify the relationship between population density, inflation, and unemployment on the human development index, GNP, export-import, and urbanization in the category of developed and developing countries using the Panel Seemingly Unrelated Regression (Panel SUR) with a dummy variable as a slope component. This study uses economic data from 145 countries in the world obtained through the official websites of the World Bank and the International Monetary Fund. The results showed that the Fix Effect SUR model (AIC=84915.74) was better than the pooled SUR model (AIC=114936) and Random Effect SUR (AIC=1148415). The results of the analysis using the Fix Effect SUR model show that population density has a significant positive relationship with GNP, imports, and exports. There is a significant negative relationship between the unemployment rate and GNP. In addition, the results obtained show that the effect of population density on GNP in developed countries is positive and greater. The effect of the unemployment rate on GNP in developed countries is negative and greater than that of developing countries. The results of the analysis using the pooled SUR model and the Random Effect SUR are the same conclusion where population density has a significant positive relationship to GNP, imports, and exports. There is a significant negative relationship between inflation and GNP. The effect of population density and inflation on GNP, imports, and exports in developed countries is positive and greater than that of developing countries. The effect of the unemployment rate on GNP in developed countries is negative and greater than that of developing countries.
本研究旨在确定人口密度、通货膨胀和失业对发达国家和发展中国家人类发展指数、国民生产总值、进出口和城市化之间的关系,使用面板看似无关回归(面板SUR),以虚拟变量作为斜率成分。本研究使用了世界145个国家的经济数据,这些数据是通过世界银行和国际货币基金组织的官方网站获得的。结果表明,固定效应SUR模型(AIC=84915.74)优于集合SUR模型(AIC=114936)和随机效应SUR模型(AIC=1148415)。利用固定效应SUR模型的分析结果表明,人口密度与国民生产总值、进出口呈显著正相关。失业率与国民生产总值之间存在显著的负相关关系。此外,所得结果表明,发达国家的人口密度对国民生产总值的影响是正的,而且更大。在发达国家,失业率对国民生产总值的影响是负的,而且比发展中国家的影响更大。使用汇总SUR模型和随机效应SUR分析的结果是相同的结论,其中人口密度与GNP,进口和出口具有显着的正相关关系。通货膨胀与国民生产总值之间存在显著的负相关关系。发达国家的人口密度和通货膨胀对国民生产总值、进口和出口的影响是积极的,而且比发展中国家的影响更大。在发达国家,失业率对国民生产总值的影响是负的,而且比发展中国家的影响更大。

The aim of this study was to evaluate the effect of ROS on the intensity of oxidative and energy metabolism in the blood of rats with an operational model of ischemia of the dorsal skin flap in vivo. Our studies have allowed us to establish that the modeling of an extensive skin defect is accompanied by pronounced shifts in oxidative metabolism in the blood plasma of animals. At the same time, in the absence of pathogenetic treatment, signs of oxidative stress are formed, including the intensification of free radical processes and the inhibition of general antioxidant activity in combination with the accumulation of an increased amount of lipoperoxidation products (in particular, malondialdehyde). Conducting experimental therapy with the introduction of ozone or treatment with electromagnetic radiation of the EHF band allows partially compensating for these metabolic disorders, however, the most optimal option is a combination of these factors within a single scheme. It should be noted that the results obtained are of great applied importance for the creation of innovative technologies for the complex medical rehabilitation of orthopedic-traumatological patients as a tool for influencing reparative processes in the lesion to restore and maintain tissue structures.
本研究的目的是在体内建立背侧皮瓣缺血操作模型,探讨活性氧对大鼠血液中氧化代谢强度和能量代谢的影响。我们的研究使我们能够确定,广泛皮肤缺损的建模伴随着动物血浆中氧化代谢的显著变化。同时,在缺乏致病治疗的情况下,形成氧化应激的迹象,包括自由基过程的加剧和一般抗氧化活性的抑制,以及脂质过氧化产物(特别是丙二醛)积累量的增加。通过引入臭氧或EHF波段的电磁辐射进行实验性治疗可以部分补偿这些代谢紊乱,然而,最理想的选择是在单一方案内将这些因素结合起来。值得注意的是,所获得的结果对于创造骨科创伤患者复杂医学康复的创新技术具有重要的应用意义,作为影响病变修复过程以恢复和维持组织结构的工具。

Our studies have allowed us to establish that the modeling of an extensive skin defect is accompanied by pronounced shifts in oxidative metabolism in the blood plasma of animals. At the same time, in the absence of pathogenetic treatment, signs of oxidative stress are formed, including the intensification of free radical processes and the inhibition of general antioxidant activity in combination with the accumulation of an increased amount of lipoperoxidation products (in particular, malondialdehyde). Conducting experimental therapy with the introduction of ozone or treatment with electromagnetic radiation of the EHF band allows partially compensating for these metabolic disorders, however, the most optimal option is a combination of these factors within a single scheme. It should be noted that the results obtained are of great applied importance for the creation of innovative technologies for the complex medical rehabilitation of orthopedic-traumatological patients as a tool for influencing reparative processes in the lesion to restore and maintain tissue structures.","PeriodicalId":53713,"journal":{"name":"WSEAS Transactions on Environment and Development","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49022660","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 intensive poultry industry in Kosovo fulfills a significant portion of the local demand for eggs. Considering this context, the sustainable development of this industry necessitates specific attention due to potential risks and threats. This paper aims to identify and evaluate legal risk events associated with the industry. We created a questionnaire with eight questions, using information from previous research and considering the actual conditions of the intensive poultry industry in Kosovo. Through face-to-face interviews with farmers and agricultural economists, we empirically assessed the likelihood and impact of each legal risk event. We set using a Likert scale ranging from 1 (very low) to 5 (very high). Both qualitative and quantitative methods were employed to evaluate the risk level of each event. The qualitative analysis and interpretation of the results emphasized the risk factors, which were categorized based on severity. The findings indicate that two events exhibit a mouse-like level of aggressiveness; one mirrors the aggressiveness of a rabbit, another resembles that of a shark, and four display the hostility of a lion. The quantitative analysis and interpretation of the results revealed a relatively high distribution of 75%, with a standard deviation of 9,608 euros and a considerably high coefficient of variation (95%) if these events were to occur. To mitigate the adverse impact of legal risk events, we recommend that farmers seek additional information and consult with professionals such as economists, veterinarians, animal husbandry experts, and lawyers.
科索沃的集约型家禽业满足了当地对鸡蛋的很大一部分需求。考虑到这一背景,由于潜在的风险和威胁,该行业的可持续发展需要特别关注。本文旨在识别和评估与该行业相关的法律风险事件。我们利用先前研究的信息,并考虑到科索沃集约化家禽业的实际情况,编制了一份包含八个问题的问卷。通过与农民和农业经济学家的面对面访谈,我们实证评估了每一个法律风险事件的可能性和影响。我们使用Likert量表进行设置,范围从1(非常低)到5(非常高)。采用定性和定量两种方法来评估每个事件的风险水平。对结果的定性分析和解释强调了风险因素,并根据严重程度对其进行了分类。研究结果表明,这两个事件表现出类似老鼠的攻击性水平;一个反映了兔子的攻击性,另一个类似于鲨鱼,四个表现出狮子的敌意。对结果的定量分析和解释显示,如果发生这些事件,分布相对较高,为75%,标准偏差为9608欧元,变异系数相当高(95%)。为了减轻法律风险事件的不利影响,我们建议农民寻求更多信息,并咨询经济学家、兽医、畜牧业专家和律师等专业人士。

Detergents are commonly used in workplaces and homes. Users are at increased risk of exposure to significantly higher concentrations. Many detergents are toxic when we are not careful about them. Chemical detergents have harmful effects on the environment. They can cause climate change, kill fish and wildlife, and make aquatic environments uninhabitable The main objective of this study was to assess the awareness and attitude of Applied Science Private University (ASU) students toward detergents. A cross-sectional study was conducted at ASU. A questionnaire containing 40 questions was given to the study category of students (129 students, 38 males, and 91 females), tabulated, and analyzed using SPSS 17 to measure the awareness and attitude of students toward detergents. 70.5% of the total sample were females, 86% from scientific colleges, and 42.6% from the first-year level of study. There were no significant differences between awareness and attitude attributed to gender, college, or study year level. Workplaces and homes that ensure good ventilation to reduce occupational diseases, injuries, and accidents have the highest mean of 2.3721 (SD = 0.62587) with high attitude. Read indicative, alert, and warning signs of detergents and hazardous materials with a mean of 2.3333 (SD = 0.67700) with a high attitude. Knowledge of the import and shipping laws for hazardous detergents with a mean of 1.7674 (SD = 0.61887) with a medium attitude. Students' knowledge of the side effects of detergents on health and their general knowledge of cleaning materials and the side effects of mixing detergents is high. Students do not use detergents frequently. Female students' knowledge rates of detergents are higher than those of male students. The knowledge rates of students of science college about detergents are higher than those of students of humanities college. The knowledge rates of students in the first and second years about detergents are higher than the percentage of students in the third and fourth years. This study provides a pathway for health education to broaden a change of attitude toward detergents and household poisons.
洗涤剂通常用于工作场所和家庭。使用者暴露在明显更高浓度下的风险增加。当我们不小心的时候,许多清洁剂都是有毒的。化学洗涤剂对环境有有害影响。它们会导致气候变化,杀死鱼类和野生动物,并使水生环境不适合居住。本研究的主要目的是评估应用科学私立大学(ASU)学生对洗涤剂的认识和态度。ASU进行了一项横断面研究。向研究类别的学生(129名学生、38名男性和91名女性)提供了一份包含40个问题的问卷,制成表格,并使用SPSS 17进行分析,以测量学生对洗涤剂的意识和态度。70.5%的样本是女性,86%来自科学学院,42.6%来自一年级。性别、大学或学年水平的认知和态度没有显著差异。确保良好通风以减少职业病、伤害和事故的工作场所和家庭的平均值最高,为2.3721(SD=0.62587),态度较高。以高姿态阅读洗涤剂和危险品的指示、警报和警告标志,平均值为2.3333(SD=0.67700)。对危险洗涤剂进口和运输法律的了解,平均值为1.7674(SD=0.61887),态度中等。学生对清洁剂对健康的副作用的了解以及对清洁材料和混合清洁剂副作用的一般了解都很高。学生不经常使用洗涤剂。女生对洗涤剂的了解率高于男生。理学院学生对洗涤剂的了解率高于人文学院学生。第一年和第二年的学生对洗涤剂的了解率高于第三年和第四年的学生。这项研究为健康教育提供了一条途径,以拓宽对清洁剂和家用毒药的态度转变。
