With the usage of the internet and the growing prominence of communities, like social media we have witnessed a rise in cybercrime. Among these crimes one that stands out is Intimidator, which affects both people and adults alike. The increasing incidents of cyberbullying have led to consequences such as anxiety, aggression, depression and tragically even suicide. Consequently, there is now a pressing need for content regulation on social media platforms. This research focuses on developing a model of identifying text-based bullying messages and comments by categorizing them into five distinct types; Violence, Vulgar language Offensive content, sexually explicit material, and Hate Speech. The proposed approach involves utilizing Natural Language Processing (NLP) techniques with Machine Learning methods. The dataset is initially. Processed to remove information before extracting meaningful features. Finally, the model undergoes training and testing to ensure reliable results, in detecting instances of Intimidator in text-based data.

This study was carried out in order to evaluate the current land uses, land elevation and aspect characteristics spatially by using 1/25.000 scaled digital soil maps in Nevşehir province. For this purpose, Arc GIS 10.3.1 program from Geography Information Systems (GIS) software was used and some land features were classified as spatial. As a result of the research, it was seen that dry agricultural areas dominate the area and it covers an area of 336,653.36 hectares (60.47%). It covers a part of 109180.06 hectares of meadow and pasture area. When the land elevation is examined, it is determined that the highest land level is 1985 m and the lowest land level is 860 m. When the land surface is examined in general, it is seen that flat and near-flat areas are few. When the directional conditions of the lands were examined, it was seen that the lands were generally in the north oriented group.

This study experimentally investigates various heat transfer characteristics, pressure drop, friction factor, Nusselt number, and Dean Number in a double-pipe helical coil heat exchanger. The study examines the hot water mass flow rates ranging from 0.02 to 0.12 kg/s and the cold-water mass flow rates ranging from 0.055 to 0.15 kg/s. The cold-water inlet temperature was maintained at 29°C, while the hot water inlet temperature varied between 65-75°C. Based on the hydraulic diameter of the annular space between the two tubes, the Reynolds number ranged from 1000-6000. All required parameters, such as the inlet and outlet temperatures of the inner coil and annulus fluids and the flow rate of fluids, were measured using appropriate instruments. Seventy-two test runs were conducted, from which the heat transfer coefficients of the inner coil side and annulus side were calculated. The calculated heat transfer coefficients of the inner coil were compared with available correlations from the literature, and a reasonable agreement was found.

As days are progressing the effect of global warming increases rapidly through-out the world. It is a bigger threat for not only human being but also for the whole animal kingdom. If we look deeply into the reason behind global warming, there are some gases behind it. In this regard, the most harmful gas which is responsible for global warming is 𝑪𝒐𝟐 . Emission of carbon from different industry helps in formation of 𝑪𝒐𝟐. So, utility of carbon emission reduction technology is indispensible for both developed and developing countries. Different Governments consider the act of reduction of carbon emission level by applying some technology as a social responsibility. Very often this technology is termed as Green technology. Also, in many situations upper bound of carbon emission level is specified to arisen more consciousness among the people. A mathematical model has been framed incorporating Green technology. Solution procedure under different structures is discussed. Numerical example has been provided illustrating this model.
随着时间的推移,全球变暖的影响在全世界迅速增加。这不仅对人类,而且对整个动物王国都是一个更大的威胁。如果我们深入研究全球变暖背后的原因,就会发现背后有一些气体。在这方面,造成全球变暖的最有害的气体是𝑪。不同行业的碳排放有助于形成𝑪。因此,无论是发达国家还是发展中国家,碳减排技术的应用都是必不可少的。各国政府都认为通过应用某种技术来降低碳排放水平的行为是一种社会责任。这种技术通常被称为绿色技术。同时,在很多情况下,碳排放上限的规定也引起了人们更多的意识。一个包含绿色技术的数学模型已经建立起来。讨论了不同结构下的求解过程。最后给出了数值算例。

This study was carried out within the scope of spatial evaluation of majör soil groups, land slope, erosion degrees, soil depth classes, and other soil properties by using 1/25.000 scaled digital soil maps in Niğde province. Arc GIS 10.3.1 software, which is one of the Geography Information Systems (GIS) software, was used for spatial analysis. Classification results were evaluated according to the "Soil and Land Classification Standards Technical Instruction" published by the Ministry of Agriculture and Rural Affairs in 2005. As a result of the research, it was seen that the class covering the largest area in terms of major soil groups was brown soils with 224466.1 ha. Red-brown soils cover the least area with 45.4 ha. Areas with a steep slope with a 5% slope on the land slope cover the largest area of 140325.7 ha. Areas with a very steep slope of 6%, on the other hand, cover the least area with 69064 ha. Areas with C class (50-90 cm) soil depth in the study area cover the largest area with 294054.7 ha. The areas with E class (0-20 cm) soil depth were seen in the least area with 22203.5 ha. In terms of soil erosion classes, the most common erosion class is III. These are areas with a degree of erosion risk and their total area is 269374.8 ha. It has been determined that areas with slightly salty, alkaline, weak, and adequate drainage are seen in an area of 234.1 ha in the research area. Areas with insufficient drainage have an area of 7350.9 ha. In this study, spatial analysis of some land and soil properties in Niğde province was carried out and distribution maps were produced. It is thought that the results of the research will make significant contributions to the agricultural investments operating in the region.

The grain-size analysis in the sandstones of the Renji Formation (Barail Group) and Bhuban Formation (Surma Group) in parts of the Barak Basin, western Manipur, India was carried to determine the grain size distributions, modes of sediment transportation and depositional environment. The grain size of the Barail sandstone ranges from 2.3ɸ to 3ɸ and their grains show well sorted to moderately well sorted, symmetrical to coarse - skewed as well as nearly very fine – skewed and mesokurtic nature whereas the grain size of the Surma sandstone varies from 2.7ɸ to 3.4ɸand these grainsdisplay moderately well sorted to moderately sorted, coarse - and symmetrical skewed, mesokurtic to very leptokurtic nature. The Kurtosis analysis shows that the Barail siliciclastic sediments have been sorted in normal energy condition, whereas the Surma siliciclastic sediments likely have been sorted in normal to low as well as high energy conditions. Generally, the Barail and Surma sandstones show unimodal distribution. A shallow marine environment has been envisaged for the deposition of sediments of both the Barail and the Surma sandstone, dominated by saltation process.
通过对印度曼尼普尔邦西部巴拉克盆地部分地区仁济组(Barail组)和布班组(Surma组)砂岩的粒度分析,确定了该地区砂岩的粒度分布、输沙方式和沉积环境。巴勒砂岩的粒度为2.3 ~ 3度,表现为分选好~中等、对称~粗斜、近细斜、中斜;苏尔玛砂岩的粒度为2.7 ~ 3.4度,表现为分选好~中等、粗斜~对称、中斜~极细斜。峰度分析表明,Barail的硅屑沉积物是在正常能量条件下分选的,而Surma的硅屑沉积物可能是在正常到低能量和高能量条件下分选的。Barail和Surma砂岩总体上呈单峰分布。Barail和Surma砂岩的沉积环境被设想为浅海环境,以跃移过程为主。

The grain size of the Barail sandstone ranges from 2.3ɸ to 3ɸ and their grains show well sorted to moderately well sorted, symmetrical to coarse - skewed as well as nearly very fine – skewed and mesokurtic nature whereas the grain size of the Surma sandstone varies from 2.7ɸ to 3.4ɸand these grainsdisplay moderately well sorted to moderately sorted, coarse - and symmetrical skewed, mesokurtic to very leptokurtic nature. The Kurtosis analysis shows that the Barail siliciclastic sediments have been sorted in normal energy condition, whereas the Surma siliciclastic sediments likely have been sorted in normal to low as well as high energy conditions.

This study was carried out in Nevşehir province of Turkey with the aim of spatial evaluation of major soil groups, land use capabilities and subclasses by using 1/25.000 scaled digital soil maps. For this purpose, the Geography Information Systems (GIS) software, Arc GIS 10.3.1 was used. As a result of the research; The area covered by brown soils corresponds to 50.68% (304248.49 ha) of the total area. Hydromorphic soils were observed in an area of 7.23 ha. VI. class lands are in the majority in Nevşehir province and the ratio of these lands in the total area is 39.06% (234491.21 ha). II. class lands are 9.48% (56934.79 ha) of the total area and VIII. class lands cover the least area. These lands correspond to 5564.41 ha and 0.93% of the total area. It was determined that the areas with slope and erosion damage and soil insufficiency in the study area correspond to 62.80% of the total area and cover an area of 376990.54 ha. In the study, the spatial distribution maps of the land use capabilities will form the basis for the studies to be carried out for agricultural purposes in Nevşehir province.
