Characteristics of microwave drying of wood strands with different initial moisture contents and geometries were investigated using a commercial 10 small microwave oven under different power inputs. Temperature and moisture changes along with the drying efficiency were examined at different drying scenar­ ios. Extractives were analyzed using gas chromatography=mass spectrometry (GC=MS). The res...

Hazelnut fruit samples were collected over 2 years (2020 and 2021) subjected to four different drying temperatures (100, 120, 140, 160 °C) times of 15, 30, 45, 60 min using conduction drying. The analyses performed showed that at had a significant effect on the change in composition hazelnut shell fuel its mass properties. Comparing untreated two after drying, it can be seen 2020, treatment cau...

Introduction: Stress is a main factor influencing brain functions as revealed by the electroencephalogram (EEG) recordings. Moreover, different stress durations seemingly cause perturbations in brain waves and lead to mental disorders. This study investigates the effects of acute, sub-chronic and chronic stress on EEG in rats.  Methods: Twenty-eight Wistar adult male rats were randomly all...

Objective: Drying is one of the most important post-harvesting processes in agriculture. Drying method and also drying time have an important effect on the amount of energy required. In this study analysis of energy consumption for drying corn in dryer reservoir with flow of warm air and the effect of the temperature and height of product layer on the amount of energy consumption per unit mass ...

The fluidized bed drying principles for drying of tea in Bangladesh is thoroughly studied. The experiments were conducted to determine the drying curve, drying time, drying constant and dynamic equilibrium moisture contents of tea at the Bangladesh Tea Research Institute. Drying of tea in a fluidized bed dryer (Kilburn Vibro Fluid Bed Dryer) takes only 20 min for drying from an initial moisture...

The dried rhizome of Belamcanda. chinensis (L.) DC. is an important traditional Chinese medicine. Previous chemical and pharmacological investigations indicated that flavonoids may be responsible for the bioactivity of the herb. In this paper, the effects on the contents of twelve flavonoids in the three subunit parts of the rhizome of B. chinensis during the thermal drying process under treatm...

Biological samples are vulnerable to degradation from the time they are collected until they are analysed at the laboratory. Biological contaminants, such as bacteria, fungi, and enzymes, as well as environmental factors, such as sunlight, heat, and humidity, can increase the rate of DNA degradation. Currently, DNA samples are normally dried or frozen to limit their degradation prior to their a...
