Evaluating the Impact of CO2 Capture on the Operation of Combined Cycles with Different Configurations

open access: yesEnergies
In order to reduce greenhouse gas emissions associated with power generation, the replacement of fossil fuels with renewables must be accompanied by the availability of dispatchable sources needed to balance electricity demand and production.

Thermo-Chemical Instability and Energy Analysis of Absorption Heat Pumps

open access: yesEnergies, 2020
This paper presents the results of energy analysis of absorption heat pumps. The thermo-chemical instability term was introduced for absorption heat pumps used for heating or cooling or heating and cooling. A higher thermo-chemical instability results in

[Cutaneous absorption of chemicals].

open access: yesJournal of the South African Veterinary Association, 1987
Chemicals have become indispensible for the maintenance of health in animals and man. The route of administration of each medicament is decided by factors such as site of desired action, chemistry of the active ingredient, age and species of the patient, and frequency of administration (or desired duration of activity). In situations where the oral and

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

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 ...

DETERMINATION OF HEAVY METALS IN FOODSTUFFS BY ATOMIC ABSORPTION SPECTROPHOTOMETRY [PDF]

open access: yesFiabilitate şi Durabilitate, 2021
AAS uses the atomic ownership of absorbing electromagnetic radiation at certain wavelengths of infrared (IR), visible (VIS) or ultraviolet (UV) radiation, thus providing a detectable signal proportional to the concentration of atoms.
