In recent social experiments, rental motorbikes and rental bicycles have been arranged at nodes, and environments where users can ride these bikes have been improved. When people borrow bikes, they return them to nearby nodes. Some experiments have been conducted using the models of Hamachari of Yokohama, the Niigata Rental Cycle, and Bicing. However, from these experiments, the...
Background Establishing a stand-alone cryogenic test stand is of vital importance to ensure the highly reliable and available operation of superconducting radio-frequency module in a synchrotron light source. Operating a cryogenic test stand relies strongly on a capability to deliver two-phase helium along long cryogenic transfer lines. A newly constructed cryogenic test stand...
Background The moral hazards and poor public image of the insurance industry, arising from insurance agents’ unethical behavior, affect both the normal operation of an insurance company and decrease applicants’ confidence in the company. Contrarily, these scandals may demonstrate that the organizations were “bad barrels” in which insurance agents’ unethical decisions were...
Background 1,3-Dipolar [3 + 2]-cycloaddition of nitrones to the carbon–carbon double bonds of methylenecyclopropanes yields a mixture of regioisomeric 4- and 5-isoxazolidines. The mechanisms of the reactions of N,C,C-trisubstituted nitrones with ring acceptor substituted dimethyl methylenecyclopropanes-1,2-dicarboxylate and aryl methylidene cyclopropanes-1,1-dicarboxylate have...
IntroductionNowadays, the web increasingly influences retail sales. An in-depth analysis of consumer decision-making in the context of e-business has become an important issue for internet vendors. However, factors affecting e-business are complicated and intertwined.Case description To stimulate online sales, understanding key influential factors and causal relationships among...
Canine kobuvirus (CaKVs) was a newly described virus detected in dogs in the US and Italy. To learn more about CaKVs, 5 of 106 fecal samples from diarrhea dogs were positive with CaKVs in China, and the full genome of CaKVs strain CH-1 isolated from dog with diarrhea was sequenced. The genome consists of 8186 nucleotides, excluding the 3′ poly (A) tail, and an open reading frame...
Eriobotrya japonica (Thunb.) Lindl (loquat) is an evergreen Rosaceae fruit tree widely distributed in subtropical regions. Its leaves are considered as traditional Chinese medicine and are of high medical value especially for cough and emesis. Thus, we sequenced the complete plastid genome of E. japonica to better utilize this important species. The complete plastid genome of E...
BackgroundIsoflurane and sevoflurane protect lungs with ischemia–reperfusion (IR) injury. We examined the influence of desflurane on IR lung injury using isolated rabbit lungs perfused with a physiological salt solution.MethodsThe isolated lungs were divided into three groups: IR, desflurane-treated ischemia–reperfusion (DES-IR), and ventilation/perfusion-continued control (Cont...
PurposeTo evaluate the urological journal publication productivity of Japanese urologists based on their physician years.MethodsAll original articles written by Japanese urologists and published from Japanese institutions in 6 primary urological journals between 2010 and 2014 were reviewed (N = 529 articles).ResultsThe median post-graduate years of the first and corresponding...
Background The present study investigated how much Swiss general internal medicine practitioners (GPs) know about new direct oral anticoagulants (NOACs), particularly the relevant guidelines, follow-up tests, dosing adjustments, indications and complications.
