No doubt Information Technology (IT) nowadays is involved in almost all of our modern lifestyle in one form or another; simple tasks like making a phone call or reserving a table for dinner will not take place without the interference of IT. If this is the case in simple life tasks, then it would be more appropriate and practical to use IT in education. Maritime education is a vocational education to a great extent. The best educational method in any vocational education is on-site training, backed up by theoretical lectures. Most of Maritime Educational and Training Institutes (METs), and because of number of factors, are doing it exactly the other way around, Theoretical lectures backed up by on-site training. This paper is trying to illustrate and discuss how to resolve this dilemma and amend the MET’s educational policies in order to put more vocational reality weight into their theoretical education with the usage of information technologies.

This experiment was done on jute-PALF union fabric produced from twill weave structures. The aim of this attempt is to find out how physico-mechanical properties like tensile strength, abrasion resistance, drape co-efficient, bending length and flexural rigidity of the produced fabric is influenced by the fabric design in order to increase the uses of natural fibers instead of manmade fibers. Two fabric samples; 3/1 twill and 2/2 twill were produced by local hand loom from same ends/inch and picks/inch in value. Jute yarn of 241 Tex (7 lb/spy) was used in warp direction and PALF yarn of 345 Tex (5 lb/spy-2ply) was used in weft direction. From the experiment, the comparative results of both samples on tensile strength, abrasion resistance, drape co-efficient, bending length and flexural rigidity are investigated to exhibit the effect of twill structures to perform the task for diversified use and domestic and industrial purposes.

The present air-conditioning system produces cooling effect by refrigerants like Freon, Ammonia, etc..Using these refrigerants can get maximum output but one of the major disadvantages is harmful gas emission and global warming. These problem can be overcome by using thermoelectric modules (Peltier effect) air-conditioner and their by protecting the environment.The present paper deals with the study of Thermoelectric air conditioner using different modules is discussed. Thermoelectric cooling systems have advantages over conventional cooling devices, such as compact in size, light in weight, high reliability, no mechanical moving parts and no working fluid .

The research explained in this project was carried out to analyze and design a point absorber wave energy convertor that has ability to survive extreme weather conditions and the need to achieve cost-efficiency while achieving high capacity. In this project an attempt is made to integrate the two technologies of wave energy convertor to achieve greater electricity production. An approach is made to minimize the cost of production of wave energy convertor. The two technologies are merged to gain the advantages of both in simple and efficient way.

A plate heat exchanger uses metal plates to transfer heat between two fluids. The metal plates are made up of stainless steel because of its ability to withstand high temperatures, its strength and its corrosion resistance. PHE is use in industries such as chemical, food and pharmaceutical process and refrigeration. The attempt made in this paper is to study the pressure drop in accessories of plate heat exchanger and to observe which geometry of inlet pipe gives the best results. Using simulation. Computational Fluid Dynamic (CFD) is a tool used in this simulation which consists of ICEM CFD and FLUENT. Volume meshing in ICEM is an important part to be considered before doing simulation in FLUENT as a solver.

As a result of global warming and rise in temperature, the Arctic region witnessed melting of ice. The technological development for the extraction of oil and natural gas in the Arctic in addition to political instability and piracy in the Middle East pushed the Nordic countries (Germany, Russia and Canada) to do research, studies and experiments to take advantage of these resources and to exploit the short distance to transfer trade between Western countries (Europe, America and Canada) to the east countries(Japan, China and South Korea). Two German ships succeeded in September 2009 to sail from a port in South Korea to the Dutch Rotterdam port across the North Sea along the northern Russian border Northern Sea Route 2013, (Information Office), followed by the success of the Russian gas tanker «Baltika» to sail from the Russian city of Murmansk in the August 14, 2010, to the Chinese city of Shanghai, accompanied by the nuclearicebreaker" 50 years of Victory" across a route inside the territorial waters of the coast of northern Russia from the Arctic Oceancarrying 70 tons of gas condensate to be a substitute for the southern route through the Suez Canal. Projections indicate that the volume of trade passing across the Northern Sea Route NSR in 2015 to be 4 million tons and may reach to 65 million tons per year in 2020 and to 120 million tons in 2030 (Keil, 2014)
