Comparison on Modelling of Drying Kinetics of Granular Polymers PA6 by Diffusion Models and Normalization Method [PDF]

open access: yes, 2012
In this work, the drying behaviour of single granular PA6, hanging in the flow direction of hot air in a drying chamber, was investigated. In the experiments, the air was passed through the chamber at contant very low velocity in the drying chamber of ...

Combined Soil Physical Stress of Soil Drying, Anaerobiosis and Mechanical Impedance to Seedling Root Growth of Four Crop Species

open access: yesPlant Production Science, 2007
Soil compaction often creates combined physical stresses of drought, anaerobiosis, and mechanical impedance in field soil. This paper aims to analyze the effect of combined and independent soil physical stresses on crop root growth to find out the ...

Measurement and analysis of shrinkage stress of expansive soils during drying process

open access: yesYantu gongcheng xuebao, 2019
During the expansion process, the expansive soils will produce expansion stress and vice versa. Therefore, it is very significant to explore the change of the shrinkage stress of the expansive soils during drying. In order to investigate the relationship

Influence of vacuum on diffusion of moisture inside seeds of cereals

open access: yesҚарағанды университетінің хабаршысы. Физика сериясы, 2022
The article solves the problem of thermal injury of seeds of grain crops during drying, which are capillaryporous bodies. It is hypothesized that the use of a vacuum in the drying chamber reduces the risk of thermal stress.

Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

open access: yesFEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Effect of Distributed Superficial-Velocity in Deep-Bed Grain Drying [PDF]

open access: yes, 2000
This paper deals with influence of velocity field distribution to heat and mass transfer process in deep bed grain dryers. Two-dimensional (2D) models of deep-bed grain dryers were built by considering simultaneously momentum, heat, and mass transfer in ...

Constitutive Relation with Double Yield Surfaces of Expansive Soil Improved by Lime and Flyash Subjected to Wetting-drying Cycles

open access: yes工程科学与技术, 2021
The elasto-plastic stress-strain constitutive relation with double yield surfaces of expansive soil improved by lime and flyash was studied based on the ellipse-parabola constitutive model.

Effects of In-Situ Drying–Wetting Cycles on the Stress-Dependent Water Retention Behavior of Intact Loess

open access: yesAdvances in Civil Engineering, 2023
Understanding the effects of in-situ drying–wetting pattern on the stress-dependent water retention curve of intact loess is vital for addressing geotechnical problems in loess regions.

The microbiome in human skin aging

open access: yesFEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.
