A 57-year-old male steel plant worker presented with fatigue and altered liver function tests. Over the next two years, he developed cognitive decline, parkinsonism and seizures. This paper reports the clinicopathological conference at the 37th Edinburgh Advanced Neurology Course 2015 and outlines what we can learn from this case.

The aim of this study was to investigate the effect of inhibition of Marrubium astranicumleaves extract on the corrosion of carbon steel in hydrochloric acid solution by using weightloss and tafel polarization methods. Inhibition was found to increase with increasingconcentration of the leaves extract. The inhibition efficiency of this extract at an optimumconcentration of 100 mg L-1 was 99.9 %...

Deregulation of the electric power industry is making power quality a topic of increasing importance. Suitable corrective actions for the reduction of total harmonic distortion introduced into the distribution network by industrial loads are more necessary than ever. For the design of these corrective actions simulation has been proved to be a very useful tool. In this paper, the simulation of ...

The paper presents the results of the research performed by the authors on control systems and optimization for the operating process of the heating installations from the blast furnace at a steel plant. This system was developed on two relevant levels interconnected in a hierarchical control structure. The acquisition and control level using specialized microcontrollers was implemented. The su...

The present paper reports a statistical analysis of the performance of the blast furnace number X at the Bhilai Steel Plant over a period of sixteen years with the special reference to the quality and consumption of sinter . The variation in basicity and consumption of sinter, for the blast furnace data considered , is wide. The range of data covers high level to almost nil amount of raw limest...

The recent years showed a significant increase both in energy costs and social awareness for environmental concerns. In the industrial sector, these aspects affected revenues and sustainability of the most intensive energy plants, such as steel mills. The present paper describes how simulation may powerfully support production planning and the related decisions. The applic...

Nolde and Morari [10] study a steel manufacturing scheduling problem where the tasks must be scheduled such that electricity consumption matches to a pre-specified periodic energy chart. They propose a continuous time integer linear programming formulation to solve the problem. In this note, we present an alternative continuous time formulation that improves significantly the computation time.

Biogas is a sustainable fuel that stands out from other biofuels because of the major environmental and socio-economic benefits that can be achieved. This opens up enormous potential for sustainable economic growth and will also improve our energy security. An attempt has been made to find the different ways to improve the overall performance of biogas plant. The present work comprise of improv...

The voltage flicker is main factor influencing the power quality and SVC is well-proven solution. The flicker reduction requires very short response time, according to the relation analysis between flicker improvement factor and response time. SVC has a fast open-loop control function to achieve effective voltage support. The fast algorithm of flicker reduction is presented here based on synchr...
