Original scientific paper One of the most important features in lithography is the stability of the printing plates during the printing process. The offset printing plates are mainly built of aluminium foil which is processed to obtain surface structure needed for printing process requirements. Printing plate is during printing process under mechanical and chemical influence of the machine part...

This paper describes the design, implementation and testing of an intelligent knowledgebased supervisory control (IKBSC) system for a hot rolling mill process. A novel architecture is used to integrate an expert system with an existing supervisory control system and a new optimization methodology for scheduling the soaking pits in which the material is heated prior to rolling. The resulting IKB...

In recent years, timing RPCs (Resistive Plate Chambers) [1] have emerged as a novel, cost-effective technology to achieve high timing resolutions σt≤100 ps as well as high granularities, which are required for high particle multiplicities. In order to cope with rates of Φ≤700 Hz/cm (expected for Au+Au collisions), the HADES detector is being upgraded. As a part of the upgrade project, an RPCbas...

Aluminium determination was carried out in serum and dialysis fluid by a simple and reliable method of nameless atomic absorption with graphite furnace . . No preparatory procedures are required for water and dialysis fluid. In this method serum was mixed with 0.2% HNO, to allow complete combustion of the samples in order to improve analytical precision. The method has a sensitivity of 15 p...

Abstract: Equal channel angular extrusion (ECAE) is a promising technique for production of ultra fine-grain (UFG) materials of few hundred nanometers size. In this research, the grain refinement of aluminium strip is accelerated by sandwiching it between two copper strips and then subjecting the three strips to ECAE process simultaneously. The loosely packed copper-aluminium-copper laminated b...

Aims of the Meeting Aluminium is one of only a few elements to have been discussed at all levels of public life. Unfortunately, much of the debate concerning its impact upon biota, including man, has been uninformed and has served only to trivialise this important field of research. The study of aluminium and its activity in biological systems is easily justified. Its ubiquity alone suggests bi...

BACKGROUND According to the recommendations proposed at The Consensus Conference on Diagnosis and Treatment of Aluminium Overload in End-Stage Renal Failure Patients, Paris, 1992 low-dose desferrioxamine (DFO) treatment was applied for the first time in 41 acutely aluminium-intoxicated patients. METHODS AND RESULTS DFO-related neurological/ophthalmological side-effects were observed in nine o...
