Among the different types of corrosion failures, Atmospheric corrosion accounts for many failures. The corrosivity of atmosphere mainly depends on the atmospheric variables such as relative humidity, temperature, salinity etc. Development of a relationship between corrosivity and environmental variables which is known as Corrosion modeling is widely used method for the determination of corrosivity of atmosphere. For the prediction of atmospheric corrosion a corrosion model was developed and the model was calibrated by the data obtained from field exposure test that was conducted for two years in four different places in Sri Lnaka. For the validation of model’s forecasting capability, the exposure test carried out for the calibration of model in two locations were continued up to five years and two exposure tests were conducted in another two different locations. According to the Test results the model shows good forecasting capability in the areas that are not more closure to coastal line. This paper describes the work carried out to validate the model for forecasting and prediction capability.

Thermal comfort in air conditioned office environments in Colombo, Sri Lanka.
Rodrigo, GA; Perera, BAKS; Rodrigo, MNN
Thermal comfort in office environments is of prime importance as it is directly correlated to the productivity of its occupants. ASHRAE Standard 55 is a prominently used thermal comfort standard across the world. However many industry experts question the applicability of the ASHRAE Standard 55 for tropical regions. The research findings revealed that majority of occupants were dissatisfied of the ASHRAE Standard 55.

Comparison for pullout strength of bone joint using conventional and non-conventional drilled hole
Singh, G; Jain, V; Gupta, D
Bone screw joint plays a vital role for the sustainability of orthopaedic surgery. Before fixing screw, bone need to be low pullout strength of bone joint is a common problem which faced by the patient with passage of time. The causes of this problem initiate during the surgery. Bone faces many mechanical and frictional forces during the drilling which causes necrosis and micro cracks which can affect the sustainability the bone joint. This research gives the comparative study for pullout of bone joint using two very different concept of bone drilling. Results shows that conventional drilling causes micro cracks which will lead to low pullout strength of bone screw joint. The non-conventional technique used in this study can be an initiate to reduce the losses during bone drilling.
