Biological safety cabinets are frequently relied upon to provide sterile work environments in which hazardous microorganisms can be safely handled. Verification of correct airstream velocities does not, by itself, ensure that adequate protection will be achieved under all users. Instead, the concentration of microorganisms in a cabinet operator's breathing zone must be measured during typical c...

Tamarind is an indigenous tree in India and every parts of the such as root, stem, fruit leaves are widely used nutritional, medicinal industrial applications. The stickiness tamarind a major concern during deseeding process, it can be reduced by drying. growers processing industries still using sun drying method, which time-consuming unhygienic that produces poor-quality product. In this conte...

Introduction The stability of the paper machine short circulation, forming and press section are tightly connected. A new online measurement, IQInsight, now provides true instantaneous MD and CD profiles from the press section. This unique measurement device provides new possibilities for stabilizing and optimizing paper machines. The accurate and continuous moisture profile just after the pres...

Spray dryers are widely used in the chemical, pharmaceutical and food industries to turn liquid products into free flowing powder. To increase the energy efficiency and improve the product quality, the dryer in question combines drying in four stages, instead of single stage drying. In this paper, we present our latest developments within advanced process control for the four-stage spray dryer....

Microbiological research on and diagnostics of highly pathogenic microorganisms, namely bacteria and viruses, have to be conducted in containment laboratories in order to contain the infectious material. We are therefore referring to the ‘‘Concept of Biocontainment’’ – a concept, which dates back to the 1940s, when the first biosafety cabinet (BSC) class III was developed at the US Army Biologi...

Perception of moving sound sources obeys different brain processes from those mediating the localization of static sound events. In view of these specificities, a preprocessing model was designed, based on the main perceptual cues involved in the auditory perception of moving sound sources, such as the intensity, timbre, reverberation, and frequency shift processes. This model is the first step...

Dryer system is a controlled plant which is normally used in chemical industry. The proper modeling of this system facilitates its maintenance and keeping. Normally this is not an easy task, unless having a complete model of the process, due to sudden and nonlinear events. In this paper the linear identification of dryer plant in Arak petroleum, is introduced according to the Autoregressive wit...
