Strain rate

In this study, a series of Consolidated–Undrained triaxial compression tests were conducted at a constant axial strain rate, with a small unloading and reloading during the monotonic loading to investigate the effect of various densities and curing times on the mechanical properties of Liquefied Stabilized Soil (LSS).

In this paper, the continuous stiffness measurement (CSM) indentation is employed to investigate fatigue mechanical properties of structural steel under cyclic loading. For this purpose, several representative analytical approaches were introduced to estimate the basic mechanical properties including Young’s modulus and indentation hardness from the characteristics of the loading/unloading curves.

The rate of antibiotic resistance in Helicobacter pylori (H.pylori) is increasing in Vietnam in recent years and has become a main challenge in the management of H. pylori infection. Data about the resistance remains different depending on the time, demography and especially the methods of determining the antibiotics susceptibility. To determine the antibiogram of H.pylori strains isolated from a population in Central Vietnam to clarithromycin, levofloxacin by E-test and disk diffusion, compare two diffusion methods.

In this thesis, a numerical model with detailed reaction mechanism which is tailored for studying the behaviour of combustion of natural gas has been introduced and validated with available experimental data. The numerical model attempts to comprehensively simulate the physical conditions (temperature and pressure), equivalent ratio, and fuel dilution and strain rate effect in the laminar flames.

Herein, a combined analysis of Global Navigation Satellite System-derived strain rate maps, in accordance with recent seismicity, was presented to reveal that the N-S extension is accommodated primarily by strike-slip faulting of the İzmir-Balıkesir Transfer Zone (İBTZ), where a counter clockwise rotation (~25–100°/Myr) along the vertical axis is dominant. The results indicated that strike-slip segments within the İBTZ show variable transport sense and amount of slip along them, and they connect by hard linkage relay ramps with the dip to oblique slip normal faults.

The Aegean region is one of the most seismically active regions in Turkey and comprises the Hellenic Arc, Greece, and Western Turkey. The Tuzla Fault, which lies between the town of Menderes and Cape Doğanbey, is one of the major seismic threats in western Turkey due to its seismic potential to generate a major earthquake (M 6, near Doğanbey Cape in 1992) and proximity to the city of İzmir which sustained damage due to the earthquake that occurred in the Aegean Sea on October 30th, 2020.

In this study, 341 Bacillus sp. strains were isolated from agricultural soils of Turkey. The potent extracellular lipase producer was selected. It was identified by 16S rRNA, named as Bacillus cereus ATA179. Optimal nutritional and physical parameters for lipase production were determined. Sucrose as the carbon source, (NH4 )2 HPO4 as the nitrogen source, CaCl2 as the metal ion were obtained. The best results of physical parameters were stated at 45°C, pH 7.0, shaking rate 50 rpm, inoculation amount 7% and inoculum age 24 h.

Recently, several strains of microalgae have been studied as they contain high lipid content capable to be converted to biodiesel. Fresh water microalgae Chlorella vulgaris studied in this research was one of the proof as it contained high triacyl glyceride which made it a potential candidate for biodiesel production. Factors responsible for good growing of microalgae such as CO2 and nitrogen concentration were investigated. It was found that total lipid content was increased after exposing to media with not enough nitrogen concentration.

The addition of glucose toSaccharomyces cerevisiaecells causes reprogramming of gene expression. Glucose is sensed bymembrane receptorsaswell as (so far elusive) intracellular sensing mechanisms. The availability of four yeast strains that display different hexose uptake capacities allowed us to study glucose-induced effects at different glycolytic rates. Rapid glucose responses were observed in all strains able to take up glucose, consistent with intracellular sensing.

ThepyrGgene fromLactococcus lactisencodes CTP syn-thase (EC 6.4.3.2), an enzyme converting UTP to CTP. A series of strains were constructed with different levels of pyrGexpression by insertion of synthetic constitutive pro-moters with different strengths in front ofpyrG.These strains expressed pyrGlevels in a range from 3 to 665% relative to thewild-type expression level.Decreasing the level of CTP synthase to 43% had no effect on the growth rate, showing that the capacity of CTP synthase in the cell is in excess in a wild-type strain. ...

CCR5 is a G protein-coupled receptor that binds several natural chemokines but it is alsoa coreceptor for the entryof M tropic strains of HIV-1 into cells. Levels of CCR5 on the cell surface are important for the rate ofHIV-1 infectionand are determined by a number of factors including the rates of CCR5 internalization and recycling. Here we investigated the involvement of the actin cytoskeleton in the control of ligand-induced internalization and recycling of CCR5.
