The information use pattern of researchers in veterinary science and animal husbandry was studied by analysing 3888 citations of 26 doctoral dissertations submitted in Bangladesh Agricultural University during the period 1990 to June/2005. This study reveals that researchers under study have primarily depended on periodicals of veterinary science and allied branches for their source of information. The geogrqphical and chronological scattering of citations has also been included. The information inferred in the paper may be of help to Agricultural University Libraries to arrive at a need-based consideration in the selection and acquisition of journals within the limited resources.Keywords

Parts of a mechanical system or structure operating, or located, in corrosive environment get corroded gradually, and after a period of operation, it may fail prematurely, thus increasing cost of servicing and maintenance. There are various solutions which can be used to protect components or structures from the detrimental effect of their surrounding environment. Metal cladding is one of the solutions which are used widely and is economical. In the present experimental investigation, duplex stainless steel electrode is taken for cladding employing gas metal arc welding process. Tests are carried out on low alloy steel plates under different parametric combinations. Metallographic study and corrosion test are performed to evaluate changes in microstructure and corrosion behaviour of the clad portion respectively. At a welding voltage of 28 V, weld current of 145 A, and weld speed of 516 mm/min, when heat input is 0.38 kJ/mm, corrosion rate is found to be minimum. Hence, this parameter combination may be recommended for cladding to obtain more service life of components under similar corrosive environment.- An Investigation on the Anti-Corrosion Characteristics of Stainless Steel Cladding

Cladding through GMAW can be done on surfaces of components and structures exposed to corrosive environment to raise their service life. Corrosion resistant materials are clad up on to a corrosion prone material up to a desired thickness. Since clad materials are basically of different compositions, they are dissimilar in nature. In the present work, cladding of austenitic stainless steel (316) is done on to low alloy steel specimens under varying parametric combinations. Clad quality including metallography is studied on clad specimens at different locations of it. Corrosion tests performed on clad specimens show substantially less corrosion pits present on the surface of clad portions than that on the surface of unclad portion. At a weld voltage of 26 V, weld current of 145 A, and weld speed of 535.8 mm/min, with a heat input of 0.338 kJ/mm, corrosion rate is observed to be the minimum among the experiments conducted, and hence, can be recommended to adopt.Keywords

Components or structures that are continuously subjected to corrosive, or erosive environment, need repair or replacement at frequent intervals involving loss of time and money. To overcome this problem, components or structures can either be made of alloys with good corrosion or erosion resistant properties or they can be clad with these alloys up to a desired thickness. The first solution is found out to be costlier than the latter. In this experimental investigation, cladding of austenitic stainless steel (316) on low alloy steel flats is done under different parametric combinations. Metallographic study and corrosion tests are performed on the clad specimens. Corrosion tests performed on both dad and unclad portions show that corrosion pits on the surface of the clad portions are remarkably smaller and lesser than those on the surface of the unclad flats. At a weld voltage of 28 V, weld current of 145 A, and weld speed of 420.6 mm/min, with a heat input of 0.46 kJ/mm, corrosion rate is observed to be the minimum in the domain of experiments conducted, and hence, may be recommended.
