Materials and Methodology Selection of reasonable ratio of vegetable oil in mixed fuel in order to match the international requirements for marine fuel and also to reduce exhaust gas emissions is very hard task.
However, the NOx emission as key criteria for marine fuel in accordance with the requirement of Annex VI, MARPOL 73/78 is not satisfied for PO10, PO15.

These two materials are now dominating the field of TLD material research.
In the present scientific world, ionizing radiations have been found very useful in engineering, medicine, science and technology.
Some high temperature peaks in some TLD materials (e.g.
While there is a need to date the older materials, it is also important to be able to date younger materials of few years old.

Oscillography Based Analysis of the Arc Stability in Manual Welding with Coated Electrode in Pulsed Current BURCĂ Mircea1,a * and LUCACIU Ioan2,b 1 Materials and Welding Engineering Department, Politehnica University Timisoara, 1 M.Viteazu Blvd., 300222, Timișoara, Romania 2 Industrial Ingineering Department, University of Oradea, 1 Universitații Street, 410087, Oradea,Romania amburca55@yahoo.com, bilucaciu@uoradea.ro Keywords: pulsed current, pulsed welding,coated electrod, arc stability, oscillography of welding parameters, frequency of pulse Abstract: Welding in pulsed current is specific to welding procedures carried out in MIG / MAG and WIG shielding gases environment, and which is appealling from both technological and process quality points of view because of the advantages this procedure provides, especially controlling the transfer mode and the power introduced into components.
During the high level pulsed current both the melting of the basic material and electrode material take place.
Experimental research Arc oscillography by recording key process parameters namely: the welding current and arc voltage respectively is a modern method of analyzing the stability of the arc and the metal drips transfer phenomena from the electrode tip through arc column.

Introduction The result of visual strength grading is the attribution of indicative values or allowable stress levels, for prediction of key properties, which allow for the mechanical characterization of the material.
This allowed to obtain the mechanical properties related to the material itself and its defects rather than to the state of conservation.

Medium-term planning often involves making decisions on material requirements planning (MRP) and establishing production quantities or lot sizing over the planning period, so as to optimize some performance criteria such as minimizing overall costs, while meeting demand requirements and satisfying existing capacity restrictions.
Acknowledgement This research work is a part of PhD thesis which has been carried out at the Department of Industrial and Production Engineering (IPE), Bangladesh University of Engineering and Technology (BUET).
