Motor vehicle traffic and its accompanying pollution have been a major environmental concern for decades. With approximately1.2 billion vehicles in operation today and more on the way, Earth’s atmosphere continues to absorb massive amounts of harmful emissions from a billion internal combustion engines on a daily basis. However, the problems don’t end with emissions. Roads and…
Proper preparation of the surface is the most important factor in achieving the bond between Ardex and the concrete surface being treated. No matter which topping or overlay is used to level, smooth, or repair a substrate’s surface, it will only be as strong as the surface to which it is bonded. Concrete Overlays Can Improve Looks…
Materials engineering is an important discipline of engineering that has assisted other technologies to improve the variety of products being produced globally. This science has improved the characteristics of existing materials and has also contributed to produce materials with improved properties. History of Materials Engineering The science of materials engineering has been used since the…
Protection Of Masonry During Construction It is necessary to protect masonry during construction when the mortar is green or when masonry has not been laterally supported, against damage due to rain, frost, storm, etc. It is also necessary to protect some vulnerable parts of masonry such as jambs, corners and sills and expose masonry, during…
Home automation activities are becoming increasingly important nowadays in providing more comfort and security for the home residents. Reports are available in the past concerning the development of devices and units needed for implementing the smart home (two websites, 2009; Jorge Caleira Nunes et al, 2004; Renato Nunes, 2003 and Balasubramanian and Cellatoglu, 2008). Each…
Determining the cause of structural failures is the challenging discipline of forensic structural engineering. Determination of civil and criminal liabilities drive many such investigations, but there are also valuable lessons to be learned from these failures. Not So Elementary, My Dear Watson Collecting facts to recreate the scene of a crime has been a fascinating…
Water, a substance composed of the chemical elements hydrogen and oxygen and existing in gaseous, liquid, and solid states. It is one of the most plentiful and essential of compounds. A tasteless and odourless liquid at room temperature, it has the important ability to dissolve many other substances. Indeed, the versatility of water as a solvent is essential to living organisms. Life is believed to have originated…
Due to the highly complex nature of both human and physical systems, the ability to comprehend them and model future conditions using a watershed approach has taken a geographic dimension. Satellite remote sensing and Geographic Information Systems (GIS) technology have played a critical role in all aspects of watershed management, from assessing watershed conditions through…
Several types of earthquake damages may occur, and the extent of damage caused will be influenced by the severity of the earthquake, location of site from epicenter, and several other factors. Damage can be minimized by proper design analysis according to the parameters of earthquake engineering. Basics of Earthquake The shaking of the earth, because of…
High definition induction logs are more accurate and efficient than the conventional well logging methods. HDIL, as they are popularly known as are an important part of well-logging and ensure precise resistivity data and hydrocarbon traces of a newly dug well. Induction logging of oil and natural gas wells started after the Second World War….
