Cost-effectiveness Analysis of CO2 Reduction in the Automobile Sector

Various problems relating to energy and the environment clearly exist, such as global warming and a steep rise in the price fossil fuels, and resources. These problems should be addressed in the medium term or long run. As for the abatement of greenhouse gas emission, active discussions have been held on the stage of world politics to achieve the long-term goal. Although various approaches have been proposed by several research institutions and countries, sufficient studies have not yet been conducted on the roles of individual countries and sectors. Specifically, in the automotive transportation sector wherein oil demand and CO2 emissions are estimated to rise in the future with the marked progress of motorization in developing countries, it is increasingly important to study these subjects. We focused on the automotive transportation sector and studied the CO2 abatement potential and its cost performance in this sector. This article reports the results of the study.energy and the environment, Climate change, automotive transportation

En Face Images Using Ultra-Widefield Optical Coherence Tomography in 2 Cases of Traumatic Hypotony Maculopathy before and after Surgical Intervention

The aim was to investigate the structural changes of the retina using en face ultra-widefield optical coherence tomography (OCT) images during the treatment of hypotony maculopathy with traumatic cyclodialysis. Case 1 was a 43-year-old male patient with visual crowding in his left eye (metallic wire injury that occurred 3 weeks previously) who was referred to our department. Although best-corrected visual acuity was 20/20 in his left eye on initial evaluation, intraocular pressure was 6 mm Hg. Case 2 was a 20-year-old male patient with visual crowding in his left eye (baseball ball injury that occurred 4 weeks previously) who was referred to our department. Although best-corrected visual acuity was 16/20 in his left eye on initial examination, intraocular pressure was 5 mm Hg. Surgical interventions were performed in both cases. En face ultra-widefield OCT images were able to be used to trace dynamic changes before the intervention and up to 1 year later. The images obtained in these two cases made it possible to confirm the progress from wrinkles on the surface of the retina to normalization of vascular structure and improvement of ellipsoid zone disruption. En face ultra-widefield OCT is useful for monitoring multilayer structures of the retina in hypotony maculopathy cases

A Σp\Sigma p scattering Experiment at J-PARC and the Analysis Status

International audienceJ-PARC E40 aims to measure the differential cross sections of the Σ^±p elastic scatterings and the Σ^−p → Λn conversion. A clear peak of Σ^− was observed in a missing mass spectrum of the π^−p → K^+X reaction and recoil protons from the πp elastic scattering were successfully observed in the data taken in the summer 2018. The rest of data taking is coming in the spring 2019
