The capillary pressure was found to be too capricious to be accurately measured, but it is a negligible quantity. The coefficient of apparent expansion of mercury in the new Jena glass thermometer 16m was found to be 0藱0001571 between 0掳 and 100掳....
Nickel iron alloys are also used. Their coefficient of expansion is very small, meaning that the pressure reading is not affected by the temperature of the instrument. Mechanical and pneumatic instruments have an accuracy of 0.5% of the scale. SIZE: Hydraulic pressure gauges have diameters of 63...
Knowledge about the vegetation history of Sardinia, the second largest island of the Mediterranean, is scanty. Here, we present a new sedimentary record covering the past ~ 8,000 years from Lago di Baratz, north-west Sardinia. Vegetation and fire history are reconstructed by pollen, spores...
The estimated selection coefficient for the GFP allele is consistent between the two experiments; as the estimates have overlapping confidence limits ranging from s ¼ 0.14 to s ¼ 0.20. Among experiments, the mean selection coefficient of the GFP allele was of 0.16. Together, the probability ...
Olieboomspoort is one of the few rock shelters in the vast interior of southern Africa documenting pulses of occupation from the Acheulean until the end of
To evaluate the thermal shock behaviour, samples containing Vickers indentations were tested in quenching and the growth of the radial cracks was determined. Glycerine was chosen as the quenching fluid to minimize the effect of boiling on the heat transfer coefficient and to assure mild heat ...
The combination of thermal and mechanical properties—thermal conductivity, thermal expansion coefficient, Young's modulus, and toughness—improve the thermal shock resistance of the alumina–aluminum titanate composite in terms of critical temperature increment (>30%). The suitable structural properties of...
A glycerine purification unit and a transesterification unit make up the HC process. Ethanol recovery is considered only in the MS process, while it is disregarded in the HC process due to the high conversion rate of over 99%. Figure 1. Transesterification reaction process [28]. 3. Modelling...
bacterial strains to the examined AgNP foils differed largely, as evidenced by the standard deviation and coefficient of variation values (Table S1). The growth inhibition zone of theS. aureusATCC 29213 (susceptible to all antimicrobial agents) was higher than the mean values calculated forS. aureu...
These include glass beads and subrounded sands of various grain sizes (Fraction A to D). The particle size distribution (PSD) curves are shown in Figure 1. All materials were poorly sorted, as they possessed a low uniformity coefficient. Figure 1. The particle size distributions (PSDs) of ...
