Comparison of drying characteristics of Thompson seedless grapes using combined microwave oven and hot air drying

AbstractComparison of drying characteristics of Thompson seedless grapes using combined microwave oven and hot air cabinet dryer was investigated. The drying rate curves indicated the absence of a constant-rate drying period in all drying methods. Within a certain microwave power range (75–900W in the current study), increasing microwave power speeds up the drying process, thus shortening the drying time. No benefits were seen when increasing drying time from 30 to 120min when grapes drying started in hot air cabinet dryer and finished in microwave oven for 1min at any power level. The higher value of energy consumption during grapes drying belonged to hot air cabinet dryer alone as drying method with value of 564.5MJ/kgwater evaporated. The average total soluble solids was 90.4° Brix when drying was achieved by microwave oven followed by hot air cabinet dryer, meanwhile, it was 90.2° Brix when drying was achieved by hot air cabinet dryer followed by microwave oven. The total soluble solid was 92° Brix when drying process started and finished in hot air cabinet dryer alone. The average drying ratio was 4.21 when drying was achieved by microwave oven followed by hot air cabinet dryer; meanwhile, it was 4.19 when drying was achieved by hot air cabinet dryer followed by microwave oven. The hot air cabinet drying method had higher drying constant ‘k’ compared to the other two methods. The microwave oven followed by hot air cabinet dryer as a drying method achieved 78% of the optimum selection percentage. However, the optimum drying method has a selection percentage of 100%

ARDD 2020: from aging mechanisms to interventions

Aging is emerging as a druggable target with growing interest from academia, industry and investors. New technologies such as artificial intelligence and advanced screening techniques, as well as a strong influence from the industry sector may lead to novel discoveries to treat age-related diseases. The present review summarizes presentations from the 7th Annual Aging Research and Drug Discovery (ARDD) meeting, held online on the 1st to 4th of September 2020. The meeting covered topics related to new methodologies to study aging, knowledge about basic mechanisms of longevity, latest interventional strategies to target the aging process as well as discussions about the impact of aging research on society and economy. More than 2000 participants and 65 speakers joined the meeting and we already look forward to an even larger meeting next year. Please mark your calendars for the 8th ARDD meeting that is scheduled for the 31st of August to 3rd of September, 2021, at Columbia University, USA

Ultra-Low Energy CNFET-Based Ternary Combinational Circuits Designs

The embedded systems, IoT (Internet of Things) devices, and portable electronic devices spread very quickly recently. Most of them depend on batteries to operate. The target of this work is to decrease energy consumption by (1) using Multiple-valued logic (MVL) that shows notable enhancements regarding energy consumption over binary circuits and (2) using carbon nanotube field-effect transistors (CNFET) that show better performance than CMOS. This work proposes ternary combinational circuits using 32 nm CNFET: Ternary Half Adder (THA) with 36 transistors and Ternary Multiplier (TMUL) with 23 transistors. To reduce energy consumption by utilizing the unary operator of the ternary system and employing two voltage supplies (Vdd and Vdd/2). The result of extensive HSPICE simulations regarding PVT (Process, Voltage, and Temperatures) variations and Noise Immunity Curve (NIC) show the improvements of the proposed designs up to 25% in transistors count and up to 98% in energy consumption reductions. Further, increasing the robustness of process variations and the noise tolerance compared to recent similar designs. CCBYScopu
