Ultra-high performance concrete (UHPC) has been accepted rapidly attributed to its superior mechanical performance and the split Hopkinson pressure bar (SHPB) is being widely utilized to evaluate the dynamic compressive properties of UHPC. Numerous studies have been performed on the dynamic behaviour of...

Review Reports Versions Notes Abstract Loess accumulated in the Negev desert during the Pleistocene and primary and secondary loess remains cover large parts of the landscape. Holocene loess deposits are however absent. This could be due low accumulation rates, lack of preservation, and higher erosio...
Versions Notes Abstract Gas hydrate blockage in pipelines during offshore production becomes a major problem with increasing water depth. In this work, a series of experiments on gas hydrate formation in a flow loop was performed with low flow rates of 0.33, 0.66, and 0.88 m/s; the effects ...
2.3. Real-Time Polymerase Chain Reaction (PCR) For each digester sample, a 0.2 mL sub-sample was centrifuged twice and the supernatant was removed each time to minimize concentrations of possible PCR inhibitors and DNA from cell debris. Total DNA was extracted using an automated nucleic acid ext...
Versions Notes Abstract Drug resistance often emerges from mutations in solute transporters. Single amino acid exchanges may alter functionality of transporters with ‘de novo’ ability to transport drugs away from their site of action. The PfMDR1 transporter (or P-glycoprotein 1) is located in the...
Versions Notes Abstract This study investigates the time-varying effects of three types of oil price shocks (oil demand, supply, and risk shock) on exchange rates by applying the time-varying parameter structural vector autoregression stochastic volatility (TVP-SVAR-SV) model. Through examining the...
The six polymorphic loci were amplified by Polymerase Chain Reaction (PCR) using the specific primers (Table 2) described by Huber et al. [29] and Chambers et al. [30]. The loci were amplified in a final volume of 7 μL containing 0.7 μL of the DNA (50 ng/μL), 3.5 of Master...
In another publication, we showed via Fickian diffusion modeling that such measurements can provide the opportunity to derive crystallization kinetics from thin liquid films of about 150 µm. By applying the diffusion–reaction theory, we showed that a constant mass transfer coefficient 𝑘𝑔kg ...
