Numerical analysis of the influence of the design type of the channel of heat network on its thermal conditions and heat loss

open access: yesИзвестия высших учебных заведений: Проблемы энергетики, 2017
The results of the numerical analysis of thermal regimes and heat loss of the two-channel underground heating networks with using the convective-conductive model of heat transfer are presented. The two-dimensional coupled stationary problem of convective-

Development of a low-temperature driven absorption chiller with vapour exchange double-lift absorption cooling cycle (Experimental proof of 7 ℃ chilled water output driven by 60 ℃ hot water with a prototype)

open access: yesNihon Kikai Gakkai ronbunshu, 2022
Conventional single-effect absorption chillers require an 80~90 ℃ heat source to supply 7~8 ℃ chilled water for air conditioning applications. However, it is difficult to recover lower temperature heat sources such as 60 ℃ hot water with single-effect ...

HEAT LOSS DURING ANAESTHESIA

open access: yesBritish Journal of Anaesthesia, 1978
The superficial and deep body temperatures of 23 patients were studied during prolonged anaesthesia for microscopic surgery of the fallopian tubes. The patients were divided randomly into three groups, receiving either halothane 0.5%, halothane 1% or low-dose fentanyl as a supplement to nitrous oxide, oxygen and myoneural block.

Heat loss along the pipeline and its control measures

open access: yesSN Applied Sciences, 2022
Highlights Formulas are derived to calculate temperature drop and heat loss, and the causations of all results are shown in detail. Relative heat loss increases almost linearly with the pipeline length, thermal conductivity and reciprocal of insulation ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

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 ...
