In certain cases, and particularly for the BrO3-/Ce4+/malonic acid system, oxygen seems to inhibit oscillations and the mechanical stirring in a N2 atmosphere has no significant effect on the oscillations. However, for the BrO3-/Ce4+/Cyclohexanon and BrO3-/Ce4+/Cyclopentanon systems under specific experimental conditions, stirring plays a determining part and oxygen has no notable effect on the oscillations.

Abstract. The variables tested in the study consist of Good Government Governance measured by the rank of Indonesia Governance Index (IGI) and the size of the legislative by using the number of members of the provincial parliament, and also local government performance measured by three proxies, the GDP per capita, Poverty Rates, and independence Ratios. The study is conducted in 33 provinces in Indonesia in 2012. The results show that there is no significant effect of good government governance on local government performance by proxy of GDP per capita. There is significant impact of good gov

Intensively evaporating liquid films moving under the action of the cocurrent gas flow in a microchannel are promising for the use in modern cooling systems of semiconductor devices with high local heat release. This work has studied the dependence of the critical heat flux on the inclination angle of the channel. It has been found that the inclination angle in the plane parallel to the flow has no significant effect on the critical heat flux. Whereas the inclination angle in the plane perpendicular to the flow, on the contrary, significantly changes the value of the critical heat flux. Howeve

Even though the sensitivity of direct dark matter search experiments reaches the level of about 10−45 cm2, no confident signal of dark matter has been observed. We point out that, if dark matter is a vector boson, the null result in direct dark matter search experiments may be due to the destructive effects in dark-matter–nucleon elastic scattering. We illustrate the scenario using a modified Higgs portal model that includes exotic quarks. The significant cancellation can occur for a certain mass gap between new heavy quark and dark matter. As a result, the spin-independent dark-matter–nucleon
