Treatment of Dyeing Waste Water by Using Garlic Extract as a Natural Coagulant
Abstract: Coagulation is the process of removal of very fine particles by forming bigger flocs in the water. But this process is not much efficient in waste water treatment as in the treatment of drinking water. This is because of adding chemical coagulant for the treatment of waste water. Use of chemicals in treatment of dyeing waste water causes formation of non-biodegradable sludge. To avoid this we made an attempt in …

Implementation of Close Range Photogrammetry to Evaluate Distresses at Asphalt Pavement Surface
Abstract: Roadway pavements surface deteriorate with time because of traffic loading, environment conditions, and poor pavement maintenance management. The aim of this research is to implement close range photogrammetry technique for evaluation of the pavement surface distresses. The assessment was based on comparison with the traditional visual inspection method and validation of its equivalency with visual evaluation. The asphalt concrete pavement surface distresses such as (cracking type and crack width, patching …

Field Investigation on the Use of Mobile Phone While Driving
Abstract: While talking through mobile phone, drivers are much less aware of what is happening on the road around them; fail to see road signs, maintain proper lane position and steady speed; react more slowly and take longer to brake. Moreover, drivers are more likely to enter unsafe gaps in traffic, feel more stressed and frustrated, and are more likely to tailgate the vehicle in front. This paper demonstrates field investigation …

Assessment of Pedestrian Walking Characteristics at Erbil CBD
Abstract: To enable and encourage walking, understanding of the characteristics of pedestrian movements is vital. The restrictions on vehicular movement, and scarcity of parking lots had changed the whole traffic movement to the unserviceable condition. Therefore, walking is considered as the most efficient mode of transportation at Erbil CBD area. In developing countries like Iraq, however, the recognition of the importance of pedestrian walking studies is still infancy; the published data …

Fracture and Failure of Recycled Aggregate Concrete (RAC) – A Review
Abstract: In the world, many countries put into effect the renewal plans and/or the laws and/or the regulations for recent engineering structures which have reached their lifetime, are risk prone and have been built lacking quality engineering, or without considering urban planning. Hence, many structures are demolished and this situation increases the amount of construction and demolition waste (C & DW). Also, resource consumptions are rapidly increased due to excessive constructional …

Behaviour of Vertically Loaded Piled Raft
Abstract: In order to understand the load-settlement behaviour and load sharing of piled raft resting on sand soil, 1-g model tests were conducted.The parameter studied were the influence of pile spacing and number of piles. The testing program includes tests on models of unpiled raft and rafts on 4 and 9 piles. The model piles beneath the raft are non-displacement piles.The improvement in ultimate bearing capacity is represented by load improvement …
