Impurity ion transport by filamentary plasma structures

open access: yesNuclear Materials and Energy, 2019
We have studied the impurity ion transport by a filamentary plasma structure with the three-dimensional electrostatic particle-in-cell simulation. The effective diffusivity of the impurity ions transported by a filamentary plasma structure has been ...

Effective Isentropic Diffusivity of Tropospheric Transport [PDF]

open access: yes, 2014
Tropospheric transport can be described qualitatively by the slow mean diabatic circulation and rapid isentropic mixing, yet a quantitative understanding of the transport circulation is complicated, as nearly half of the isentropic surfaces in the ...

Investigation of the effect of temperature and pretreatment on the rehydration capacities of dried nectarine slices

open access: yesActa Scientiarum: Technology, 2017
 In this study, the effect of temperature and pretreatment on the rehydration capacity of nectarine slices dried either with pretreatment and under ambient conditions (`natural´) at 50°C in a cabinet dryer was investigated.

Continuum Derrida Approach to Drift and Diffusivity in Random Media

open access: yes, 1996
By means of rather general arguments, based on an approach due to Derrida that makes use of samples of finite size, we analyse the effective diffusivity and drift tensors in certain types of random medium in which the motion of the particles is ...

Study of functioning of heat exchanger in soils with different thermal diffusivity

open access: yesГеофизический журнал, 2018
It was found with the help of mathematical model of the process of heat exchange between the air moving in vertical heat exchanger and the massif of soil, which connects energetic factors of the soil heat exchanger with its parameters as well as natural-

Sirolimus for Extracranial Arteriovenous Malformations: A Scoping Review of the Evidence in Syndromic and Non‐Syndromic Cases

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Arteriovenous malformations (AVMs) are rare, high‐flow, vascular anomalies that can occur either sporadically or as part of a genetic syndrome. AVMs can progress with serious morbidity and even mortality if left unchecked. Sirolimus is an mTOR inhibitor that is effective in low‐flow vascular malformations; however, its role in AVMs is unclear.

Investigating the in-/through-plane effective diffusivities of dry and partially-saturated gas diffusion layers [PDF]

open access: yes, 2018
In this study, the effective oxygen diffusivity in the dry or partially-saturated gas diffusion layer (GDL) is numerically investigated by an oxygen diffusion model in GDLs reconstructed by a stochastic method.

Improved Procedure for Natural Convection Garlic Drying

open access: yesActa Technologica Agriculturae, 2020
Vegetable drying is an energy consuming procedure despite the fact that it is the most efficient way to preserve agricultural products. This study investigates a new way to dry good quality garlic at lower cost.
