Production of liquid fuel and activated carbon from mahogany seed by using pyrolysis technology
No full textThe renovation of biomass waste in the form of Mahogany seed waste into bio-fuel as well as activated carbon by fixed bed pyrolysis reactor has been taken into consideration in this study. The mahogany seed in particle form is pyrolyzed in an enormously heated fixed bed reactor with nitrogen as the carrier gas. The reactor is heated from 4000C to 6000C using a external heater in which rice husk and charcoal are used as the heater biomass fuel. Reactor bed temperature, running time and feed particle size have been varied to get the optimum operating conditions of the system. The parameters are found to influence the product yields to a large extent. A maximum liquid and char yield are 49 wt. % and 35 wt. % respectively obtained at a reactor bed temperature 5000C when the running time is 90 minutes. Acquired pyrolyzed oil at these optimal process conditions were analyzed for some of their properties as an alternative fuel. The oil possesses comparable flame temperature, favorable flash point and reasonable viscosity along with somewhat higher density. The kinematic viscosity of the derived fuel is 3.8 cSt and density is 1525 kg/m3. The higher calorific value is found 32.4 MJ/kg which is significantly higher than other biomass derived fuel. Moderate adsorption capacity of the prepared activated carbon in case of methyl blue & tea water was also revealed
A feminist foremother: critical essays on Rokeya Sakhawat Hossain
No full textThis volume looks at the life and works of Rokeya Sakhawat Hossain (1880–1932), arguably Bengal’s earliest and boldest feminist, revered as a crusader for the emancipation and advancement of women, in particular Bengali Muslim women. Through her spirited writings and her activism, Rokeya challenged the two pillars of patriarchy – hierarchical family structures and religious dogma. She demanded that the ‘family’ be restructured on the basis of gender equality. A devout Muslim, she asked that women be recognised as human beings in their own right within practices of Islam.
Born into an orthodox Muslim family, for Rokeya, the most vital way in which women could empower themselves was through education. The Sakhawat Memorial Girls’ School in Kolkata, started by Rokeya in 1911, still stands as an enduring testament to that belief.
This collection of biographical and critical essays places Rokeya within the socio-cultural and historical context of her times to better appreciate her literary and social contributions in the face of the formidable challenges she faced as a Bengali Muslim woman. The essays also aim to understand why the extraordinary vision she had, not just for women but for an ideal, more gender-just society, continues to be as radical, powerful and relevant today, almost a century after her death.
This volume will be a valuable asset to students and scholars of women’s and gender studies, as also of South Asian literature and culture
Poverty in small-scale fishing communities in Bangladesh: Contexts and responses
No full textThis thesis explores the causes of poverty and its manifestation in coastal small-scale fisheries in Bangladesh, the ways in which fishers cope with or overcome poverty, and possible measures supporting poor fishers to escape poverty. In a first approach towards exploring the poverty context, Paper I situates poverty in small-scale fisheries within a wider vulnerability analysis. The paper portrays the livelihoods of small-scale fishers in Bangladesh as being threatened by different factors, such as a rapidly changing and fragile resources base, lack of physical and subjective safety and security, exploitative labour and financial relationships, and social and political exclusion. Consequently, the majority of small-scale fishers in Bangladesh live on the margin of existence, where they are extremely vulnerable to shocks such as environmental disasters. Without any effective buffer against crises, as Paper II identifies, recurring shocks and ongoing risk exposure are major factors pushing fishers into poverty. As an example, Paper III analyzes the situation of nomad fishers who have been moved from their land and who lead a vulnerable mobile life in search of livelihoods on water. Nonetheless, the fishers constantly attempt to get out of their disadvantaged situation, and in this process they employ a combination of different livelihood strategies, such as income diversification and patron-client relationships. Of the different livelihood strategies, migration is of particular importance: Paper IV shows that migration contributes to the emergence of translocal livelihoods, in which mobility serves not only as a way to escape poverty and vulnerability but also to enhance their capacities and / or to explore new opportunities. Finally, this thesis offers a number of suggestions including both protection and promotion components. To prevent a downward spiral into poverty, several buffers need to be created, for example reducing dependency on fisheries by creating job opportunities in non-fishing occupations. Intervention from the state is also required to minimize risks and free individuals from their lack of freedom, which is rooted in both natural and anthropogenic causes (Paper V). To make their agency effective and to increase the overall capacity and well-being of the communities, an enhanced access to land and education facilities and other socio-economic capitals could lead to an empowerment of poor fishing households and facilitate the participation in the local economic and political process. The study particularly highlights that the contribution of women in income generation and family decision making plays a positive role in accumulation of assets - a way out of poverty for small-scale fishers in Bangladesh

Reverse engineering for the subsequent creation of relational models
No full textData’s massive production has changed how we live, work and collaborate. As accessing large databases becomes increasingly affordable and widely available, numerous data-intensive applications have emerged in various fields, including scientific research, healthcare, sports, industry, and many more. However, many datasets are poorly structured and designed, often containing missing, non-existent, or incorrect documentation, and lacking essential design information. When this type of data is required for modern research, whether for statistical analysis or artificial intelligence, it is crucial first to understand its structure, which can be both challenging and time-consuming. Furthermore, identifying relationships between tables and columns requires significant time and effort. Manual processing not only increases the chances of errors but also adds to the costs. Nevertheless, if we can identify key relational properties and data dependencies from a dataset, it is possible to generate a relational model by combining these properties.
To solve this problem, we will design and develop a system that automates the identification of important relational properties and the generation of a complete relational model from existing data. Our research will focus on exploring various methods and techniques of database reverse engineering, relational models, and data dependencies. By combining these methods, we aim to create a web-based application that accepts a database as input and generates both key relational properties and a complete relational model as output. In addition, we are developing a user-friendly interface to use the system for data analysis and optimization. To evaluate the effectiveness and accuracy of our application, we will conduct tests with different databases and compare the results.
Overall, our study will provide a systematic approach to the reverse engineering of relational databases and the automation of the extraction of key relational properties and data dependencies. Our system will help users to understand the structure of their databases. In this study, the system will support MySQL and PostgreSQL databases. In the future, further research will be conducted to expand the system’s capabilities to support other types of databases and different dataset formats
