In recent years trenchless technology methods have been used extensively to replace and rehabilitate deteriorated pipes. Among these methods cured-in-place pipe (CIPP) is perhaps the most commonly used rehabilitation method with more than 70 million linear feet being installed around the world over the past 30 years. Development of a limit state design approach for the correlation of the theoretical (design) buckling resistance to actual buckling (experimental) resistance for the purpose of evaluating the degree of conservatism in ASTM F1216 has been discussed. Guidelines to practicing...

Premature plate end debonding failure is the main weakness of plate bonded strengthened beams which can be minimized by end anchors. The main objectives of this research were to study the behaviour of steel plate and CFRP laminate strengthened r.c. beams, the effects of U and L shape end anchors to prevent plate end debonding and the effects of L shape intermediate anchors to eliminate premature shear. Nine rectangular beams were tested. Design methods were proposed to obtain the dimensions of steel plate and CFRP laminate. U and L shape end anchors were used on steel plate and...

Human Computer Interaction (HCI) emerged as a field of research with the purpose of studying the interaction between user and computer technology. In the challenging world every system is build to satisfy users needs by some specific operation in the system but the more important challenge is to create a usable or user-friendly system. Usability is acted with end-user by an interaction between user and the system. This interaction is maintained by user interface. But to the software engineer, usability is just one of the many aspects that must be taken into account in the development process...

Torture has become synonymous with the law-enforcement agency which affects the credibility of rule of law in Bangladesh. The major aim of this study was to explore the nature of torture in police custody from victim perspectives in Bangladesh. The additional aims were to analyze the causes and consequences of torture in police custody and find out the drawbacks to prevent torture victimization. This study was based on the triangulation of case study, content analysis and key informant interview through integration of both quantitative and qualitative manner.

Arsenic was used more than 2400 years ago in Greek and Rome as a therapeutic agent and as a poison. In current therapeutics use of arsenic as a drug is limited. Recent studies indicate that people of different countries are at higher risk of arsenic toxicity as underground water in parts of the world is drained by deadly arsenic. This book deals with the effect of arsenic on binding of three common non-steroidal anti-inflammatory drugs; paracetamol, aspirin and diclofenac sodium to bovine serum albumin. A detailed literature review on arsenic contamination and health hazards related to...
