FUTURE OF ROAD SAFETY IN INDIA :A CASE STUDY  TO IMPLEMENT ‘VISION ZERO’ POLICY ABSTRACT The present report provides a comprehensive review of road safety scenario in India from a public health perspective. Data sources for the review include published and unpublished reports from National Crime Records Bureau (2016), Ministry of Road Transport and Highways (2016) as well as global reports and independent research studies / reports/ unpublished documents. The report focusses on Road Traffic Injuries, deaths, disabilities, risk factors, injury patterns and distributions, as well as the current Indian response to this burgeoning epidemic. This summary report in conjunction with the detailed report entitled “Advancing Road Safety in India-- implementation is the key “ and “Advancing Road Safety in India-- facts and figures” provides in-depth information on all aspects of road safety and the current road safety initiatives from the Indian region. These reports are aimed at policy makers fr

Get an overview to learn the Basics of properties of cement and know how the carbon dioxide is being removed                          ABSTRACT Concrete is the most widely used building material in the world because of its beauty, strength, and  durability, among other benefits. Concrete is used in nearly every type of construction, including  homes, buildings, roads, bridges, airports, and subways. And in an era of increased attention to the  environmental impact of construction, concrete performs well when compared to other building  materials. As with any building product, the production of concrete and its ingredients does require energy  that in turn results in the generation of carbon dioxide, or CO2. The amount of CO2 produced during  manufacturing and the net impact of using concrete as a building material is relatively small. The  following features of concrete construction help minimize its carbon footprint. Atmospheric concentrations of CO2 are expressed in units of parts per

!!Find your way to know the Harbor  basic concept like Breakwater which play a crucial role in that system!! Basic Definations Breakwater→ The protective barrier construct to enclosed harbors and to keep the harbor water undisturbed by effect of heavy and strong seas called Breakwater.It is mainly used for safe Anchorage for ships and also to facilitate loading of cargo Trestle→ They are lighter peir design to withstand vertical loads as principal forces.In location where trestle not subjected to earthquake forces and height above firm bottom is less than 8m batter pile are omitted.In shallower water trestles constructed by overhead method. Mole→ Inner side of break water is constructed for Quay for cargo handling and so known as Mole.Mole found economical than trestles when water depth less than 3m.In no case mole height exceed 8m.The top of mole should not be 4m to 5m more above low water Wall acting as a breakwater Classification of Breakwater:- Breakwater are mainly classified int
