Rhenium-catalyzed insertion of terminal alkenes into a C(sp(2))–H bond and successive transfer hydrogenation

Treatment of aromatic aldimines with terminal alkenes in the presence of a rhenium catalyst, [HRe(CO)(4)](n), gives 2-alkenylbenzylamines in good to excellent yields. This reaction proceeds via the insertion of the alkene into a C-H bond at the ortho-position of the imino group of the aromatic aldimine followed by sequential beta-hydride elimination from the formed alkyl rhenium intermediate and then by hydrogenation of the imino group of the aldimine

Analysis of dynamic characteristics of fluid force induced by labyrinth seal

Flow patterns of the labyrinth seal are experimentally investigated for making a mathematical model of labyrinth seal and to obtain the flow induced force of the seal. First, the flow patterns in the labyrinth chamber are studied on the circumferential flow using bubble and on the cross section of the seal chamber using aluminum powder as tracers. And next, the fluid force and its phase angle are obtained from the measured pressure distribution in the chamber and the fluid force coefficients are derived from the fluid force and the phase angle. Those are similar to the expression of oil film coefficients. As a result, it is found that the vortices exist in the labyrinth chambers and its center moves up and down periodically. The pressure drop is biggest in the first stage of chambers and next in the last stage of chambers

On an Explicit Duck Solution and Delay in the Fitzhugh–Nagumo Equation

AbstractThe existence of delay in the FitzHugh–Nagumo equation was proved by J. Su. It is shown that an explicit duck solution and delay exist in this equation under certain conditions with respect to the coefficients by using the E. Benoı̂t's criterion

Proposition of Dynamic Virtual Link for IPv6 GeoNetworking (GN6) in ETSI

A proposition to ETSI ITS WP3.First, we describe the limitation of Draft EN 302 636-6-1 V0.1.2 (2012-11). Note that this study is based on year November 2012 versions of the ETSI Standards and that the standards constantly evolve. As a result, parameters, primitives and virtual links on GN6ASL may have changed at the time of reading. To overcome the limitation, we propose Dynamic Virtual Link (DVL)

Austerity in Civil Procedure and the Role of Simplified Procedures

The civil justice system has been in a constant flux in the past decades due to changes in society and litigants’ behaviour, as well as the increased factual and legal complexity of cases. The number of cases has been steadily increasing in many countries while the available budget required for more judicial staff, improving judicial case management, digitalisation of processes, and the required specialisation, has not in all instances increased at the same pace. This was worsened as a result of the recent financial crisis that affected many countries around the globe and has prompted governments to cut back on public expenditure. Austerity further challenges the demands of effective justice within a reasonable time,1 as is in the European context notably enshrined in Article 6 of the European Convention on Human Rights (ECHR). The financial crisis also led to a decrease in the funding of legal aid by the government in a number of countries, challenging access to justice for more vulnerable litigants in particular

AN ANALYSIS OF PHILIPPINE AND JAPANESE NAVAL ASSETS FOR HUMANITARIAN ASSISTANCE AND DISASTER RELIEF (HADR) OPERATIONS

Located in the Typhoon Belt of the Pacific, the Philippines and Japan experience strong tropical cyclones every year that affect millions of people living near or within the coastal areas. When the magnitude of a disaster reaches a national level of response, the navies of both countries are mandated to augment other government agencies in support of disaster relief and response operations. Because time is of the essence, ships ready for sea near the affected areas are usually the immediate choice for deployment. We analyze the strongest tropical cyclones that devastated both countries and the resulting government responses to determine the most efficient and effective type of ship for Humanitarian Assistance and Disaster Relief (HADR) operations. The parameters we use in the analysis are the ships’ current capabilities, the process to select ships for deployment, and the HADR policies of both countries, which result in the recognition of critical and non-critical ship’s capabilities. The analysis also reveals the potential use of the amphibious capability for humanitarian logistics in coastal areas. This research may also serve as a guide for the United States Navy or other foreign navies in sending ships to any countries in East Asia and the Pacific region whenever international support is sought.Santö Kaisa, Japan Maritime Self-Defense ForceLieutenant Commander, Philippine NavyApproved for public release.
