Exchange of Heat Radiation between Human Body and Urban Environment: Characterization in Visible, Near-Infrared, and Far-Infrared Regions

open access: yesApplied Sciences, 2022
In urban environments, radiation energy from the sun becomes a heat load on the human body. The radiation energy can be divided into visible, near-infrared, and far-infrared wavelengths. Far-infrared radiation is re-emitted from structures that have been

Microwave heating - the influence of oven and load parameters on the power absorbed in the heated load [PDF]

open access: yesCzech Journal of Food Sciences, 2002
The microwave power is a parameter greatly influencing the rate of heating. Several authors reported on certain differences between the rated power output as a parameter used by oven manufacturers in the labelling of ovens, and the power actually delivered to the heated product.

Performance Prediction and Parametric Analysis of Small Diameter Heat Exchangers Based on Distributed Parameter Model

open access: yesZhileng xuebao, 2023
Based on a three-dimensional distributed parameter model, a simulation model of a small-diameter heat exchanger in the indoor unit of a split-household air-conditioner was established, and the performance metrics were computed, including the total heat ...

CRITICAL PARAMETERS INFLUENCING HYPERTHERMIA-INDUCED CELL DEATH IN MYELOGENOUS LEUKEMIA CELL LINE (M-NFS-60) [PDF]

open access: yesAssiut University Journal of Multidisciplinary Scientific Research, 2019
Hyperthermia is sufficient to induce cell death in many cancer cells. Here we investigated the effect of some parameters that modulate hyperthermia-induced cell death in myelogenous leukemia cell line (M-NFS-60).

Segmented Cladding Fiber With a High-Index Ring in Core for Wideband Single-Mode Operation in Any Bending Orientation

open access: yesIEEE Photonics Journal, 2021
A resonant-ring-assisted large mode area segmented cladding fiber (RR-SCF) with a high-index ring in the core is proposed. Numerical investigations of the effects of the high-index ring on the leakage losses of guiding modes, mode area, and electric ...

Heat Loading of Steam Boilers Heating Surfaces [PDF]

open access: yesManufacturing Technology, 2017
This paper deals with the comparison of an analytical solution of the temperature field of a steam boiler pipe membrane wall using a numerical method calculation in the COSMOS/M programme. The result analysis showed that analytical calculating methods which are limited to 1D and 2D task types can be used for the approximate calculation of temperature ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
