The SI units together with the SI prefixes provide a logical and interconnected framework for measurements in science, industry, and commerce. In some cases, quantities are commonly expressed in terms of fundamental constants of nature, and use of these constants or “natural units” is acceptable...

The invention relates to measuring equipment and can be used in the construction of autonomous systems measuring physical quantities, operating independently from the person at all stages of processing to sensing and utilizing the measuring information. The method does not require pre-establishing the re...
(6) (7) where are the SU(3) structure constants. The quantities (8) play the role of incoming gluon polarization vectors; here are the initial proton momenta, are the gluon longitudinal momentum fractions and are the (non-zero) gluon transverse momenta. The above effective vertices ensur...
Typically, a series of four tetramer quantities were used, ranging from 30 pmol to 1 pmol in a volume of 100 µl DPBS (including around 1 mM calcium and magnesium ions) with 1% BSA. Cells were incubated with tetramers for 45 min on ice before washing with DPBS. Washing ...
Thus, it is evident that ALE extracts do not only contained sugars, but also proteins in (likely) non-negligible quantities. Humic acids also represented a major fraction of ALE extracts. The Na+-ALE spectra obtained with FTIR were very similar to the ones of humic acids isolated from ...
In addition, small quantities of formic acid, lactic acid, furfural, hydroxyl acetone, and traces of phenol were detected in the condensed liquid sample [11]. Many attempts are being made to characterise physicochemical properties of pyrolysis liquid products [12]. However, the inherent complexity ...
predecessor Cys-SO2H was favoured by less oxidizing treatment conditions. Due to its chemical instability, no traces of sulfenic acid (Cys-SOH, 136.0068 m/z) could be detected. S-nitroso cysteine (Cys-SNO, 149.0011 m/z) was found in small quantities when N2or N2/O2was added to...
Physical quantities such as signal area and position are reconstructed from the raw data by the custom-developed PAX data processor. PAX operates in five stages: (1) identify “hits” due to digitized photon signals in each PMT channel individually, (2) group hits into clusters, (3) compute...
The system records the interfacial tension response to this area deformation, using the software CONTACTO® to calculate complex interfacial dilatational modulus (E) and all related quantities (Maldonado-Valderrama et al., 2013). The complex dilatational modulus is in the general case a complex ...
