The growth of cities in different developing nations including Bangladesh is posing several challenges in the making of sustainable cities. Growth of infrastructure whilst maintaining the sustainability of urban sprawl is a major challenge in these areas experiencing rapid development. This research aims to address the issues of achieving the efficient and effective technology for an accurate and timely monitoring and cost-effective urban infrastructure through the utilization of airborne remote sensing technologies. This paper describes and compares several machine learning models, including YOLOv5, YOLOv7, YOLOv8 and a custom model developed by us that enhances the performance of object detection of infrastructure conditions on images captured by drones. Our study is based on a unique data set specifically developed for Bangladesh encompassing multiple aspects of urban features as well as the context of infrastructure expansion across different regions. This dataset is critical during the training and testing stage since the combination of features that works well for our models is tailored for optimal use in urban environments in Bangladesh. In the developed approach, the created machine learning models will be used to identify and recognize the exact building, the roads, and other urban infrastructure features in the images that are used for training. Although our comparison and experimental tests are devoted to the measurement of the detection accuracy and calculation speed of each model, we also dedicate a section for the assessment of detection appropriateness in varied urban scenarios as well as in various illumination conditions. There is a significant improvement in many of the conclusion and result as shown for YOLOv8 and our own custom model in terms of the ability of the model to perform more accurate prediction and the ability to handle the spam case at various conditions of spatial and temporal dimensions of urbanization. The above findings suggest that using drone imagery can indeed be effective in utilizing deep learning tools for urban growth in cities enhancing urban planning. It also demonstrates the possibility of using the approach presented in our work in cities with various populations and levels of development for the most efficient management of these dynamic urban processes. The use of temporal data also have enhanced our knowledge in that it is now possible to monitor temporal changes that occur in infrastructural systems and also in making urban design prediction.The former approach means avoiding the necessary conceptual development for more effective uses of such models in real-world development of cities and communities. In conclusion, this thesis is able to show that hybrid of the latest machine learning models for infrastructure detection shows a great potential for the application to urban areas within Bangladesh and similar developing areas with a high population density in a short time. Through surveys it provides a comparison not only of the strengths and weaknesses of each model, but also the framework for future development of more responsive and sustainable urban planning applications.

Lovellois a manufacture under Taufika foods and agro industries ltd. Taufika foods and agro industries it is an organization under Taufika group. Taufika has established at 2005 by Md. EkramulHaque. He is an engineer and he worked almost 20 years for a foreign company in Malaysia. Then after 2000, he came back in Bangladesh and launched this group. The group started Taufika engineering LTD (TEL) which involved in engineering business and build of steel and RCc building, project management and Turnkey general civil construction etc. Since when it has started, it is manufacturing only healthy, Halal and savory Lovello Ice Cream prepared of imported high quality raw materials using state-of-the-arttechnology.

Our full team of INSIGHT has one aim only to make a project which will be remembered. To achieve this we find out the natural story and we select it for our project. Our project name INSIGHT which will give us a social message and we it will increase awareness in our society.SO if we want to reach there we have made our project perfectly. This project is based on VFX. That's why we need to work hard to create a composition and all other things which need for this project. First of all we have to organize our team and our team work. Then we have to develop our story and story concept with our imagination and must keep the awareness massage. We want to keep massage on our story that if we are going wrong way and if we all time disappointment with every things then something will automatically come to our life then this things control us and lead us to wrong way. That’s something’s we can called it negative power which destroy our mentality and Finley it destroy our life. This fact may be know everyone but nobody are aware about this fact. That’s why want to show this massage on our project with some special effect and seen For VFX work we are going to use Adobe after effect and Bijou and for 3d modeling, we are going to use Auto desk Maya and Auto desk max and for final editing and Adobe premiere pro and some of relative software.
Physiological responses, ion accumulation and yield performance of wheat (Triticum aestivum L.) to salt stress
(South African Journal of Botany, 2024-11) Rahman, Atikur; Ahmed, Sujat; Islam, Moshiul; Shathy, Laila Parveen; Urmi, Tahmina Akter; Haque, M.Moynul; Siddiqui, Manzer H.; Murata, Yoshiyuki
Wheat is affected by various biotic and abiotic stresses, especially salinity, which reduces the growth and yield drastically. High salinity is a major constraint for wheat productivity in many countries, including Bangladesh. With this view, here, an experiment was conducted to observe genotypic differences in physiological, ion accumulation, agro-morphological and yield performance of wheat against different levels of salinity. Experimental variables consisted of five salt tolerant genotypes (G 20–2–2, G 20–1–2, G 13–2, G 22–2, G 9–2), one susceptible genotype (G 24–2) and one standard check variety (BARI ghom 25), which assigned to four levels of salinity with electrical conductivities control (0.3), 4, 8 and 12 dS m−1. Irrespective of genotypes, salinity stress significantly decreased the yield and yield attributes. Results of analyses based on salt tolerance indices of plant growth related and yield contributing parameters, ionic balance (Na+, K+ and Na+ /K+ ratio), and stress indicators such as chlorophyll content, photosynthetic rate (Pn), stomatal conductance (gs) and transpiration rate (Tr) revealed genotypes G 20–2–2, G 13–2 and G 20–1–2 as salt tolerant, genotype G 9–2 as moderately salt-tolerant and G 24–2 and G 22–2 as salt-sensitive genotypes. Additionally, lower accumulations of hydrogen peroxide and malondialdehyde, and higher activities of antioxidant enzymes in the salt-tolerant genotypes G 20–2–2 and G 13–2 than in the salt-sensitive genotype G 24–2 indicated reduced oxidative damage in genotypes G 20–2–2 and G 13–2 relative to that in genotype G 24–2. Collectively, our findings suggest that the optimum growth and yield of salt tolerant genotypes are associated with decreased Na+/K+ ratio, increased antioxidant enzymes activity and reduced oxidative stress.
Training and Development Practices of Jamuna Bank Limited

Jamuna Bank is one of the recognized banks in our country. Commercial banks are one of the key contributors in the economy of developing countries. The act as financial intermediaries by performing of mobilizing the funds for one group and leading the same to another while making a reasonable amount of profit after meeting the cost of fund. Banking sector in Bangladesh has been pursuing the policy of expansion and growth of branches. People and the government itself are very much dependent on the services provided by the 55 banks in the financial markets. To know how well commercial banks perform actually. The banking practice of conventional banking and Islamic banking is highly different from the concept. The report begins with Introduction chapter. Then this report shows the overview of Jamuna Bank Limited. After that, the report represents Training & Development of Jamuna Bank Ltd. which shows that the value of training of development in an organization, its importance, purposes of T&D, training needs analysis (TNA), methods of T&D. Then the report shows an analysis of training and development and its importance on basis of Jamuna Bank Limited.
