Comparison of Different Methods to Evaluate Measurement Uncertainty in Bimetallic Thermometers Used in Industrial Equipment

International Journal of Technology, 2023
This paper compares different methods (Kragten, Guide to the expression of uncertainty in measurement –GUM– and Relative Uncertainty) to evaluate the measurement uncertainty in bimetallic thermometers. The motivation for the development of the work is

Thermostable neutral metalloprotease from Geobacillus sp. EA1 does not share thermolysin's preference for substrates with leucine at the P1′ position

FEBS Letters, EarlyView.
Knowing how proteases recognise preferred substrates facilitates matching proteases to applications. The S1′ pocket of protease EA1 directs cleavage to the N‐terminal side of hydrophobic residues, particularly leucine. The S1′ pocket of thermolysin differs from EA's at only one position (leucine in place of phenylalanine), which decreases cleavage ...

The effect of measurement uncertainty for HOMA-IR in assessment of insulin resistance

Medicine Science, 2019
In this study, it is aimed to estimate not just the uncertainty measurement for the parameters of glucose and insulin having role when calculating HOMA-IR, but also true positiveness and negativeness in terms of cut-off values.

Single cis‐elements in brassinosteroid‐induced upregulated genes are insufficient to recruit both redox states of the BIL1/BZR1 DNA‐binding domain

FEBS Letters, EarlyView.
Phytohormone brassinosteroid‐induced gene regulation by the transcription factor BIL1/BZR1 involves redox‐dependent DNA‐binding alternation and interaction with the transcription factor PIF4. The reduced BIL1/BZR1 dimer binds preferred cis‐elements, while oxidation alters its oligomerization state and disrupts DNA‐binding ability.

Measurement Uncertainty

, 2015
During the SFERA-II project, the measurement accuracy of a facility called KONTAS-Cp consisting of a bypass with electric heating, temperature difference measurement and a Coriolis mass flow sensor to measure thermal heat capacity (Cp) of heat transfer fluid (HTF) is enhanced and an additional Coriolis mass flow sensor is included.
