Solar magnetic tornadoes are known to be one of the mass and energy transport mechanisms from the lower solar atmosphere into the upper layers of the solar corona. A bright spiral structure with two arms is observed using high-cadence EUV images of 171, 193 and 304 Ǻ channels of Atmospheric Imaging Assembly (AIA) aboard the Solar Dynamics Observatory (SDO) on 10th of July 2011 for three hours. ...

BACKGROUND Orange-fleshed sweetpotato (OFSP) can be used to tackle vitamin A deficiency, a major public health problem in most developing countries. In East Africa, common ways of using sweetpotato include drying and subsequent storage. The aim of the study was to investigate the impact of drying and storage on the total carotenoid retention (as an estimate of provitamin A retention) from OFSP....

In this study, an artificial neural network (ANN) was developed to obtain a generalized model for predicting the direct and open sun drying process some medicinal plants. Since quality of experimental dataset can lead very performant model, in study collected from previously published papers divided randomly into three subsets, namely 70 %, 15 % training, testing, validation. Based on complex s...

Background: Sun protection materials have been one of the major concerns in pharmaceutical industry since almost one century ago. Various materials have been found to have such an effect but there are still many unknown substances that have not been discovered.Objective: To introduce a novel mineral-based sun lotion with considerable UV absorption properties compared to commercially available s...

The influence of different drying methods on physical and nutritional properties of shrimp meat was investigated in this study. Peeled shrimps were dried separately using an air-oven dryer and a tunnel solar dryer. The drying profile of shrimp meat was determined in the two drying systems by monitoring moisture loss over the drying period. Changes in color, proximate composition, and rehydratio...

It is well known that the control of a rotary dryer is difficult due to long delay times of the process. The main target of this research was to find a self-tuning technique for tuning the parameters of the fuzzy logic controller, which has been developed to the pilot plant rotary dryer located in the Control Engineering Laboratory at the University of Oulu. The aim is to improve the performanc...

The drying of solids in a continuously worked vibrated fluidised bed dryer is studied by simulations. A model considering the drying of a thin layer of particles wetted with a multicomponent mixture is developed. Particles are assumed well mixed in the direction of the airflow and only the longitudinal changes of liquid content, liquid composition and particle temperature are considered. Intera...

1. APPLICATION OF FULL FACTORIAL DESIGN IN THE MEASUREMENT OF DRYING RATES OF A ROTARY DRYER Drying is a physical separation process which enables to remove the liquid phase from a solid, semisolid or liquids by means of thermal energy. The aim of the experiment is to observe how various operational parameters affect the drying process in a rotary dryer. In drying process, heat is transferred b...

Host-seeking ticks often remain on clothing of persons returning home from work or recreation in tick habitats, and can pose at least a temporary risk to people and pets in these homes. Laundering clothing has been one of the recommendations to reduce tick exposure. Host-seeking lone star tick, Amblyomma americanum (L.), and blacklegged tick, Ixodes scapularis Say, nymphs confined in polyester ...
