In this research a fuzzy model is developed for a rotary dryer. It is applied to the pilot plant rotary dryer located in the Control Engineering Laboratory at Oulu University. Firstly, a literature review looking at the current situation of fuzzy modelling and comparison of different methods is done. One modelling method is then applied to the building of the model from data. The rule parameter...

Exposing wet hair to high temperatures can create gas bubbles within the hair shaft, leading to brittle, dry hairs in a disorder known as bubble hair abnormality. We present a case of a 61-year-old woman who presented for hair breakage over her crown. She regularly dried her damp hair with a blow dryer. Dermoscopy revealed multiple bubbles within the hair shaft, and diagnosis of bubble hair abn...

The Nano Spray Dryer B-90 offers a new, simple, and alternative approach for the production of drug nanocrystals. In this study, the preparation of steroid nanocrystals using the Nano Spray Dryer B-90 was demonstrated. The particle size was controlled by selecting the mesh aperture size. Submicrometer steroid particles in powder form were successfully obtained. These nanoparticles were confirme...

Drawbacks associated with natural convection solar dryers are encouraging the development of low-capacity hybrid drying systems which integrate renewable energy in their operation. However, information on cost-effectiveness such for decision-making by investors is lacking. This study seeks to assess financial and economic feasibility a solar-biomass dryer maize drying. A cost-benefit analysis w...

The performance of an AflaSTOP dryer which utilises biomass energy for drying maize was investigated. behaviour grains in the also investigated using ten (10) thin-layer mathematical models. models were compared based on coefficient determination (R2) and Root Mean Square Error (RMSE) values between experimental predicted moisture ratios. At average air temperature 50°C velocity 2.5 m/s, at con...
