Textile industry in Bangladesh and challenges of growth
No full textThe importance of the textile industry in the economy of Bangladesh is very high. The garments manufacturing sector earned $19 billion in the year to June 2012, one of the impoverished nation's biggest industries. Currently this industry is facing great challenges in its growth rate. The major reasons for these challenges can be the global recession, unfavorable trade policies, internal security concerns, the high cost of production due to increase in the energy costs, different safety issues specially fire, etc. Depreciation of Bangladeshi Taka that significantly raised the cost of imported inputs, rise in inflation rate, and high cost of financing has also effected seriously the growth in the textile industry. As a result neither the buyers are able to visit frequently Bangladesh nor are the exporters able to travel abroad for effectively marketing their products. With an in-depth investigation it was found that the Bangladesh textile industry can be brought on top winning track if government and others individuals takes serious actions in removing or normalizing the above mentioned hurdles. Additionally, the government should provide subsidy to the textile industry, minimize the internal dispute among the exporters, withdraw the withholding and sales taxes etc. Purchasing new machinery or enhancing the quality of the existing machinery and introducing new technology can also be very useful in increasing the research and development (R and D) related activities that in the modern era are very important for increasing the industrial growth of a country
Regulation of Foxn4 during retina development
No full textTranscription factor forkhead box N4(Foxn4) is a key regulator involved in a variety of biologic processes in development and metabolism. In particular, Foxn4 plays an essential role in the genesis of amacrine and horizontal neurons from neural progenitors in the retina. Although the functions of Foxn4 have been well established, the transcriptional regulation of Foxn4 expression during progenitor cell differentiation remains unclear. The goal of this dissertation is to identify regulatory mechanisms that define the expression of Foxn4 during retinogenesis. Four evolutionarily conserved regions (CR1-CR4) from non-coding sequences of Foxn4 gene were computationally predicted as cis-elements. Their gene regulatory potential was individually tested in developing chick and mouse embryonic retina using electroporation transfection technique with a reporter assay system. In this dissertation, I describe that CR4.2 (a 129 bp DNA fragment of CR4, located approximately 50kb upstream of Foxn4 transcription start site) functions as a novel cis-regulator that directs retinal cell type specific gene expression. CR4.2 is preferentially active in the Foxn4 expressing cells, primarily in the differentiating and differentiated horizontal and amacrine cells as shown by reporter assays. Specific trans-acting factors, e.g., Meis1, were found to interact with CR4.2 by electrophoretic mobility shift assays (EMSA). Mutation and/or deletion of the Meis1 binding motif through site-directed mutagenesis diminishes the ability of CR4.2 to drive reporter GFP expression. Furthermore, the role of Meis1 in regulating Foxn4 expression during progenitor cell differentiation was determined using a RNAi-based gene silencing assay. Knockdown of Meis1 by short hairpin RNA (shRNA) specific to Meis1 genes abolishes gene regulatory activity of CR4.2, and further diminishes the endogenous level of Foxn4 expression. In addition, cells with Meis1 knockdown failed to differentiate into horizontal cells. Taken together, I demonstrate that Meis1 transcription factor regulate the expression of Foxn4 expression and horizontal cell lineage development in the vertebrate retina via their interactions with CR4.2. These findings provide new insights into molecular mechanisms that govern gene regulation in retinal progenitors and vertebrate retinal cell development.Ph.

Effective Operations and Maintenance (O&M) practices of vehicles: a case study on LGED
No full textThis dissertation is submitted in partial fulfillment of the requirements for the degree of Masters in Procurement and Supply Management, 2015.Cataloged from PDF version of thesis report.LGED has the reputation as an “island of excellence” in the Government, with high standards of professionalism, and comparatively robust risk management systems. The report begins with a brief assessment of external environmental factors that affect LGED’s ability to adopt reforms to effectively address potential fiduciary & operational risks throughout the value chain of public expenditure for rural and urban infrastructure. This study has examined the present operations management practices of large fleet of vehicles at LGED Head Quater and analyze its effectiveness and compliance with existing rules and regulations of Bangladesh. To fulfill the overall objective of this study has undergone an in-depth procedure on verification of vehicle usages and allocation of vehicle procedures, it estimate preparation and approval procedures for maintenance, procurement process, has also checked procurement process as a tool for Public Procurement Rules (PPR-2008). Factors at the national level include weaknesses in electoral, legislative, judicial and agency accountability, outmoded civil service rules and practices, lack of national audit capacity, and high levels of corruption. Progress in nationwide reforms for combating corruption and improving financial management and procurement has been encouraging in recent years, but there is a risk that it may not be sustained by the next political government. At the sub-national level, LGED is subject to two lines of accountability. On the one hand, LGED has a sizeable budget of its own for implementing infrastructure programs at various levels of government. Here there is a strong emphasis on administrative and financial procedures to ensure the probity, integrity and effectiveness of activities. On the other hand, LGED also implements and manages rural and urban infrastructure funded under Annual Development Program allocations of sub national jurisdictions. In these cases, while there is a clearer accountability link to beneficiaries through their elected officials, risks can still arise due to weaknesses in local governance in planning, decision making and management. These risks need to be mitigated through local government reforms that will create a more efficient, effective and transparent environment within which LGED can function in the future. The report gives a brief internal organizational assessment of LGED, reviewing its evolution from a rural works component of the integrated rural development program of the early 1960s to its formalization and rapid growth as a public sector department. Key functions are assessed, including human resources and financial management, procurement, engineering and ICT systems, corporate governance, and approach to land use and resettlement. The report confirms LGED’s excellent reputation for professionalism, including quality delivery of many contracts on time and on budget. Although information and communication systems are relatively advanced in LGED compared to other government departments, the use of many different, non-integrated systems with inadequate supervision by core staff with ICT skills make it difficult for LGED to gather critical information needed to compare the results of the various projects, and complicates the reporting and control procedures within LGED (e.g. benchmarking, and detecting patterns indicating possible collusion on bids).
It has been discussed elaborately the strategy for benefits of improvement of communication system, its contribution to education sector, women empowering through women participation in rural infrastructure, community and local administration development as well as poverty reduction through participation of local level stakeholders and beneficiaries etc.S.M.

Recurrent Neural Network Encoding Decoding Translator based Prediction Protein Function and Functional Annotation
No full textProtein sequences are symbols generally different characters representing the 20 amino acids used in human proteins those sequences can range from the very sort to the very long. There are many proteins database for the sequences are known but the function and functional annotation is not. Protein function prediction (PFP) as well as functional annotation (FA) from its structure or sequence is a major field of bioinformatics at the same time how to judge how well perform these algorithms. We proposed the novel method that converts the protein function problem into a language translation problem by a new proposed protein sequence language encoded to the protein function language decoded and build a recurrent neural machine encoding decoding translator (RNNEDT) based on the recurrent neural networks model. The excellent acting on training, testing datasets exhibits the proposed system as an improving direction for PFP. The proposed system alters the PFP matter to a language translation issue as well as applies a recurrent neural network machine version model for PFP, and visualizes the annotation of biological process (BP), molecular function (MF), as well as cellular component (CP).No Full Tex
Combating Violent Extremism: A special reference to the concept of Al-Wasatiyyah
No full textIn recent years, the world has witnessed a new wave of violent extremism that has taken the lives of many innocent people of different faiths, races and nationals. The number of deaths from violent extremism and terrorism has been increased in different ways. Radicalization, an important precursor to violent extremism, is also on the rise globally. Radicalization impacts different age categories (although youth are more involved than others), different faiths, the educated as well as the non-educated, the employed and the unemployed, and men as well as women. The root causes of violent extremism are complex, multifaceted and intertwined, and related to the structural environment in which radicalization and possibly violent extremism can start to take hold. Violent extremism is the product of historical, political, economic and social circumstances including the impact of regional and global power politics. Growing horizontal inequalities are one of the consistently cited drivers of violent extremism. Critically, unemployment or poverty alone is not the only push factor inciting violence and extremism: perceptions of injustice, human rights violations, socio-political exclusion, widespread corruption or sustained mistreatment of certain groups, are also considered important push factors. UNDP declared PVE strategies in 2016 that clearly indicated the burning necessity to work with faith based organizations and religious leaders to counter the abuse of religion for terrorist purpose. However, in appointing “moderate” Islam as an antidote to “radical” Islam, the implication is that, conceptually at least, the two terms are contradistinctive. What is a “moderate” Muslim community and how would it act? What are the implications for a “moderate” community in relation to pluralist societies? And, can such a “moderate” community offer a practical response not only to “radical” Islam, but, perhaps, more importantly, to increasingly antagonistic, liberal contexts? This study aims to address those understandings based on the secondary sources

A Transient Model for Lead Pipe Corrosion in Water Supply Systems
No full textThis thesis focuses on lead related drinking water quality issues in general and on hydraulic transient induced lead pipe corrosion events in water distribution systems in particular. Corrosion is a complex phenomenon, and particularly in water distribution systems, when its already challenging electro-chemical processes are influenced by numerous other physical and chemical factors. Lead pipe corrosion can itself be influenced by both the hydraulic transients and water chemistry events. To understand the relationship among hydraulic, chemical and material processes, an existing numerical 1-D transient-corrosion model for iron-pipe based systems is modified and extended to apply for systems having lead-pipes connected in series. The coupled hydraulic transient and advection-dispersion-reaction model with improved data handling facilities is applied for analyzing the transient induced lead pipe corrosion behaviors in the system for a range of options and establishes interrelationships among the parameters.MAS
