background as the field of off-road cycling is usually remote areas with limited access to medical care, off-road cyclists are at higher risk of animal attacks and related injuries. case presentation we report two cases of dog attacks in off-road cycling and discuss the basic principles in prevention and management of such incidents. the cyclists received all 5-dose regimen of the rabies vaccin...

We demonstrate a novel chemical cycling polymerase chain reaction (ccPCR) technique for DNA amplification in a fully working device where temperature is held constant in space and time. We demonstrate successful ccPCR amplification while simultaneously focusing products via isotachophoresis (ITP) for identification of the environmental bacteria E. Coli. We electrophoretically drive the DNA samp...

The possibility of producing chemical fuel (hydrogen) from the solar-thermal energy input using an isothermal cycling strategy is explored. The canonical thermochemical reactive oxide, ceria, is reduced under high temperature and inert sweep gas, and in the second step oxidized by H2O at the same temperature. The process takes advantage of the oxygen chemical potential difference between the in...

Po2 cycling, often referred to as intermittent hypoxia, involves exposing tissues to brief cycles of low oxygen environments immediately followed by hyperoxic conditions. After experiencing long-term hypoxia, muscle can be damaged during the subsequent reintroduction of oxygen, which leads to muscle dysfunction via reperfusion injury. The protective effect and mechanism behind Po2 cycling in sk...

Cycle life often determines the commercial viability of a particular electrode chemistry or structure. The dramatic structural, crystallographic, and chemical changes that may occur in and around Li-ion battery electrodes can severely affect their cycle life. This provides a clear motive for developing an improved understanding of the nature of chemical and structural changes associated with el...

Fracture analysis of glass/epoxy composites under different thermal cycling conditions is considered. Temperature difference, stacking sequence, fiber volume fraction and number of thermal cycles are selected as the experimental design factors. The Taguchi method is implemented to design of the experiment and an apparatus is developed for automatic thermal cycling tests. The tensile tests are d...

A novel chemical tethering strategy is shown to anchor polysulfides during lithium–sulfur battery cycling, resulting in high capacity and cyclability.

Extraction of soil organic matter (SOM) fractions has been a longstanding approach to elucidating the pivotal roles of SOM in soil processes. Several types of extraction procedures are commonly used, and all provide partial information on SOM function. This report and accompanying papers summarize the information regarding SOM functions in real-world issues that has been gained through physical...
