Experimental Validation of Restoration Measures for Faulty Structures

Experimental Validation of Restoration Measures for Faulty Structures

Abdul Rashid Dar

LAP Lambert Academic Publishing
2018
pokkari
Prosperity of a society is gauged by the quality of its infrastructure. Failures of faulty structures have become a major concern for the construction industry worldwide resulting in enormous losses. Such undesirable events affect all the professionals involved adversely. Structural failures are rarely due to dearth of technical knowledge but mainly due to human error, ignorance, lack of coordination among the professionals, etc. Indeed, we learn much more from failures than success. The detailed study of each distressed structure provides valuable lessons with great potential to mitigate repeat of such failures. Unfortunately, properly documented failure studies including appropriate restoration measures and their rigorous validation are rarely disseminated widely. With the above goals in mind, this book presents the findings of a detailed investigation of distressed bridge truss of pipe rack at Srinagar, Kashmir including rigorous experimental validation of proposed remedial measures. The book will be useful for professionals like managers, design consultants, architects, site engineers, contractors as well as for researchers, students etc

Pathogenesis of Balamuthia Amoebic Encephalitis

Pathogenesis of Balamuthia Amoebic Encephalitis

Balamuthia amoebic encephalitis (BAE) is a serious human brain disease (caused by Balamuthia mandrillaris) that almost always results in death. However, the pathogenesis and pathophysiology of BAE remains incompletely understood. An important step in BAE is amoebae invasion of the bloodstream followed by their haematogenous spread. Balamuthia entry into the central nervous system most likely occurs at the blood-brain barrier (BBB) sites. However, it is not clear how circulating amoebae inside blood cross BBB. This book therefore describes the Balamuthia interactions with human brain microvascular endothelial cells (HBMEC), which constitute the BBB. It is demonstrated that Balamuthia adopt both contact dependent (adhesion to and disruptions of HBMEC monolayer followed by cell cycle arrest) and contact independent mechanism (disruption of tight junctions proteins by metalloproteases and Ecto-ATPases and degradation of extracellular matrix, which provide structural and functional support to the brain tissue leading to BBB perturbations. Future work will continue to study Balamuthia encephalitis pathogenesis which should help identify potential targets for therapeutic interventions.

Water Resources and Contamination

Water Resources and Contamination

Abdul Khaliq Alokozay

LAP Lambert Academic Publishing
2019
pokkari
In this study, the water quality of the study area was analyzed through water quality analysis. The temperature, pH, electrical conductivity (EC), and salinity of the samples were determined on the site utilizing portable meters (WTW 3310), while the concentration of heavy metal was determined with the Agilent Technologies 700 Series ICP-OES. Furthermore, Total Nitrogen (TN) were analyzed using Shimadzu TNM-1, where TOC was analyzed using Shimadzu TOC-VCPH. Principle Component Analysis (PCA), was conducted by (SPSS 25; IBM Corp.) software to find the most significant influences which are affecting the quality of water. An interpolation technique Inverse Distance Weighting (IDW) was used to obtain spatial distribution of water quality parameters, and spatial relevance to the contamination sources.

Abdul Hafeez; Satish Pandian G; Dhanabal Murugan

LAP Lambert Academic Publishing
2019
pokkari
Fluid Mechanics and Machinery is a text book meant for students of Mechanical and Civil Engineering course providing a basic understanding of the behaviour of fluids at both static and dynamic states. In this Book on Fluid mechanics and Machinery, the effects of forces and energy on liquids and gases are discussed along with with few problems to solve. In addition to Mechanics, Machineries also dealt explicitly for better understanding for the students.

Non-Similar Computational Solutions Of Jeffrey's Non-Newtonian Fluid

Non-Similar Computational Solutions Of Jeffrey's Non-Newtonian Fluid

pokkari
The study of non-Newtonian fluid flow has gained a considerable attention due to its extensive applications in engineering and different processing industries. Among the several non-Newtonian fluid models discussed in the literature, the Jeffrey's fluid model has received more attention in recent years because of its applications in chemical processing engineering, material processing, etc. The fluid model discussed in the present research work approximates reasonably well the rheological behavior of liquids like foams, paints, geological materials, cosmetics, syrups, blood, etc. This wide range of applications has encouraged us to carry out investigations on the effects of various dimensionless fluid parameters of Jeffrey's fluid model on the heat and mass transfer characteristics.
