Estimation of the Monthly Reference Evapotranspiration in the Araucanía Region, Chile, from Modis/Terra Satellite Data

Abstract We propose a multiple regression model is to estimate the monthly reference evapotranspiration (ETo), on a regional scale, from data provided by the MODIS (Moderate Resolution Imaging Spectroradiometer) sensor on board the TERRA satellite platform. The input data assumed by the model are the Normalized Difference Infrared Index (NDII) and the earth’s surface temperature,…

Effects of Some Bitumen Coating Treatments on the Corrosion Fatigue Strength of Low Carbon Steel

Abstract Fatigue strength is a basic mechanical property of a structural material and must be maintained in the application of the material for its continuous satisfactory service. In this paper, results of proper laboratory corrosion tests conducted to investigate effects of coating treatments with each of three clear bitumen samples got from important Nigerian bitumen…

A Comparison of Co-Current and Counter-Current Modes for Fischer Tropsch Synthesis in two Consecutive Reactor of Oxidative Coupling of Methane and Fischer Tropsch

Abstract The results of three cases of two consecutive reactors are studied in two types of co-current and counter-current flow in second reactor where two consecutive reactors are oxidative coupling of methane (OCM) and Fischer-Tropsch (FT) reactors. FT reactor can be fixed bed or membrane fixed bed reactor with a hydrogen perm-selective membrane. Effect of…

Experimental Investigations, Regression and Computational, Modeling and Analysis of Efficient and Effective techniques for fuel/energy conservation in iron foundries

Abstract This paper deals with development of efficient and effective techniques for fuel/energy conservation in iron foundries. The authors conducted series of experimental investigations on a self-designed and developed 200kg LDO fired rotary furnace installed in a foundry. Initially the furnace was operated as under existing conditions. The specific fuel consumption was 0.415 liters/kg and…

A Test of the Relationship Between Refractivity and Radio Signal Propagation for Dry Particulates

Abstract Radio waves or radio signals propagate through the atmosphere in wireless communication. They are affected mostly by variability in radio refractivity which leads to a decrease in their speed or rate of propagation which eventually cause propagation delay or attenuation in the troposphere.The hourly averages of radio refractivity for dry particulates during dry season…
