We perform molecular dynamics simulations of the TIP5P water model and derive the physical parameters for a simple two-scale repulsive ramp potential model. We find that the regions of anomalous behavior in the phase diagrams of both systems can be mapped onto each other if (i) pressure P and temperature T are replaced by T-T(C) and P-P(C), respectively, where (T(C),P(C)) are the coordinates of...

Synthesis The compounds were prepared by the solid state reaction of Cu, Zn, Sn, and S powders in the appropriate ratios in evacuated, sealed, fused silica tubes. They were heated at 750 °C (ramp 300 °C/h) for 170 h and then cooled down at 20 °C/h. The obtained powders were then ground and pressed into pellets which were again put into a sealed tube. The second heating sequence was: ramp 300 °C...

Utilizing ~1 W of microwave power, we achieved heating of PCR buffer with unprecedented temperature ramp rates that allowed for rapid thermocycling. Polymeric microdevices, chosen for their low cost and ease of fabrication, were constructed from polycarbonate (PC), poly(methyl-methacrylate) (PMMA), and polyester-toner (PeT) using fast, simple microfabrication via computer-aided milling for PC a...

This study explores the role of aerosil dispersion on activated phase transitions of bulk octylcyanobiphenyl (8CB) liquid crystals by performing heating rate-dependent experiments. Differential scanning calorimetry (DSC) was used at various heating ramp rates in order to probe the activated phase dynamics of the system. The system, LC1-xSilx, was prepared by mixing aerosil nanoparticles (7 nm i...

Background: Meniscus tear is a common finding in patients with anterior cruciate ligament (ACL) injury and may affectthe natural history of the injury and the outcomes of treatment. In the current study, the characteristics of meniscus tearsin patients who underwent arthroscopic ACL reconstruction were investigated.Methods: The hospital records of 1022 patients were reviewed. ...

To examine the relationship of ramp design to truck accident rates, this paper presents an analysis of truck accidents in Washington State, plus a comparison to limited data from Colorado and California. We group freeway truck accidents by ramp type, accident type, and by four conflict areas of each merge or diverge ramp. We then compare these groups on the basis of truck accidents per location...

Charcoal production is an activity that dates back over the years. The objective of study was to determine temperature and heating ramp in industrial carbonization processes using different kiln types quantify its impact on yield quality charcoal from firewood species. selection sites, types, species investigated based those with highest Mexico. Brazilian beehive kilns Arbutus xalapensis, Querc...
