In this paper the effect of adding rice husk ash on the characteristics (CBR, Proctor density and water content, Atterberg limits) of a plastic clay soil is studied. For this, rice husk ash is added to the soil in various proportions. The results obtained from the tests carried out make it possible to say that rice husk ash addition to clay soil reduces clay soil plasticity, swelling and density but increases its consistency and its CBR index.<#LINE#>Little D.N.

Five different condition of Bridge pier have been considered with investigation of all the data base of Department of Road (DOR). Available bore-hole soil database of the bridge have been utilized. The analysis showed mat me KL tnagc Pier is safer in the event of earthquakes for simulating the ground conditions encircling the pier. The performance of the RC Bridge Pier was accessed in strong ground motion records. In this study it was intended to access the seismic performance of RC bridge piers under Gazali strong motion. It was observed in the field observation that most of the bridges in Kathmandu Valley were having lowered bed due to scouring. The effect of strong vertical ground motion was investigated for possible reduction in flexural and shear strength of the pier. For this purpose, fifteen models have been developed. These fifteen models are grouped into three sets. First set consists of the five models having only horizontal direction of earthquake is applied. Second set consists of five models with horizontal & Vertical direction of earthquake is applied and third Set consist of the five models with Scouring is considered. These studies have revealed that have got profound effect on the performance of the RC structures. The lateral extent of soil mass for each of the five different bridges were fixed based on trial computations until the percentage difference in consecutive response quantities were found within the limit of 0.4%. The lateral extent for the AO is fixed as 400m, AW is fixed as 500m, AP is fixed as 400m, IP is fixed z 500m and BPIs fixed as 400m. The light damage, considerable damage and also failure damage of the Bridge pier at different bridges for different cases (AO, AW, AP and BP). The introduction of strong vertical ground motion increase the vertical displacement by 48% all bridges. It means horizontal ground acceleration (0.71g) and vertical ground acceleration (1.37g) both applied horizontal displacement increases as well as vertical displacement increases. The Nepalese RC Bridge Pier (In 1990-2015) is over safe. The Nepalese RC Bridge Pier (After 2000 and Before 1990) is designed under safe.<#LINE#>Whitman R.V., Bielak J. and Rosenblueth E.

This paper contains design of high wing, conventional tail, tricycle gear RC model with tractor configuration. This paper mainly concerns on design of RC aircraft which can be used for specialized purposes like gathering weather information, spy planes and experiments. Nose mounted motor with propeller of 8*4.5 inch is used as propulsion unit. Dihedral wing configuration is set up with a dihedral angle of 3° using Clark Y airfoil which has wing span of 96cm, chord length of 19.2cm and the aspect ratio of 5. Designed fuselage has the length of 76cm which holds the electronics component like battery and the receiver. 3D model of the design is developed in Solid Works 2016 followed by simulation of dihedral wing with air velocity of 10m/s at 5° AOA in ANSYS CFX. Simulation result showed that wing produces lift of 6.7248 N. XLFR5 was used for analysis of airfoil and model aircraft. Propulsion system analysis is carried out in MotoCalc to select best power combination for desired performance level.<#LINE#>Kaisar M.S., Uddin N. and Mashud M.
