Analysis of the regional impacts of Climate Policy in Japan

After great improvements in energy efficiency in the 1970’s, Japan has made little progress in reducing energy consumption since 1990, the base year for the Kyoto Protocol. This study is motivated by the recent growing demands among policy makers to find all possibilities for saving energy. To make informed decisions on how to save energy, policy makers need detailed information on energy consumption structures within each jurisdiction. First, in this article, I decompose national level energy intensity into efficiency and activity effects with the Fisher Ideal index, and then estimate regressions on prefecture level residential electricity demand between 1990 and 2003. It is found that national level energy intensity declined by seventy three percent from 1970 to 2003; sixty three percent of the decline may be attributed to improvement in energy efficiency.　 Energy intensity, however, has slightly increased since early 1990’s. Secondly, this paper explores the impact of reduction of carbon emission on the economy. I find that the Japanese government needs to enact the environmental taxes on a $12/ton in order to meet the Kyoto Protocol. It is also found that imposing a$12/ton environmental tax reduces Japanese GDP by around six percent and equivalent variations in urban regions fall while equivalent variations in rural regions rise.Fisher index, Energy intensity, Regional Computable General Equilibrium, Environmental taxes, Environmental Economics and Policy, Resource /Energy Economics and Policy,

A Stellar-mass Black Hole in the Ultra-luminous X-ray Source M82 X-1?

We have analyzed the archival XMM-Newton data of the bright Ultra-Luminous X-ray Source (ULX) M82 X-1 with an 105 ksec exposure when the source was in the steady state. Thanks to the high photon statistics from the large effective area and long exposure, we were able to discriminate different X-ray continuum spectral models. Neither the standard accretion disk model (where the radial dependency of the disk effective temperature is T(r) \propto r^-3/4) nor a power-law model gives a satisfactory fit. In fact, observed curvature of the M82 X-1 spectrum was just between those of the two models. When the exponent of the radial dependence (p in T(r) \propto r^-p) of the disk temperature is allowed to be free, we obtained p =0.61^+0.03_-0.02. Such a reduction of p from the standard value 3/4 under extremely high mass accretion rates is predicted from the accretion disk theory as a consequence of the radial energy advection. Thus, the accretion disk in M82 X-1 is considered to be in the Slim disk state, where an optically thick Advection Dominant Accretion Flow (ADAF) is taking place. We have applied a theoretical slim disk spectral model to M82 X-1, and estimated the black hole mass ~ 19-32 M_odot. We propose that M82 X-1 is a relatively massive stellar black hole which has been produced through evolution of an extremely massive star, shining at a super-Eddington luminosity by several times the Eddington limit.Comment: 12 pages, 2 figures, Accepted for ApJ

Surgical treatment of gastric cancer with special reference to lymph node removal

Factors influencing the prognosis in gastric cancer treated by curative resection include lymph node metastasis and the extent of invasion of the gastric wall. Lymph node metastasis can be removed surgically, but the extent of invasion is not amenable to external measures. Of these two factors, the extent of wall invasion has the greatest influence on prognosis in cases undergoing curative resection. With lymph node removal of equal extent the prognosis worsens in proportion to the depth of invasion. Further, lymph node metastasis increases with increasing depth of invasion. Metastasis was seen in Group 2 and 3 nodes in more than 60% of cancer with invasion beyond the Tunica muscularis propria (pm), indicating that wide lymph node removal is essential in cancers with deep invasion of the wall. The effects of extended radical operation on the host as illustrated by the indices of total serum protein and albumin levels were no different from those of less extensive resections. It was confirmed that extensive radical resection did not delay postoperative recovery.</p

A Database Design for CVS Pharmacy\u27s Patterson, California Distribution Center

CVS Pharmacy’s Patterson, California Distribution Center did not have an efficient and cost effective method for auditing shipped out products. The purpose of this project was to create a new system and procedure for the Patterson Distribution Center to audit shipped out container totes. The distribution center’s original method was slow, inefficient, and involved paper waste, considerable travel time, and several manual procedures. This project was meant to develop a new process and database system to provide a solution to their problem. The end goal of this project was to implement the designed method and system of auditing for daily use in the distribution center

An in vivo improvement of range of motion in shoulder contractures with relaxin in animal models

INTRODUCTION: Arthrofibrosis, which occurs in a substantial portion of the population, is a pathologic accumulation of scar tissue that presents in patients as a painful decrease in joint range of motion. Since an individual’s quality of life can be significantly impacted by arthrofibrosis and because there are limitations in current treatments, this thesis focuses on examining the use of the hormone relaxin to alleviate shoulder arthrofibrosis. METHODS: A set of 20 Sprague Dawley rats were given secondary shoulder contractures and separated into groups to examine the efficacy of relaxin using intravenous delivery, intra-articular delivery, and different treatment frequencies. The differences across groups were examined through mechanical range of motion testing as well as histologic sampling. RESULTS: Multiple doses of intra-articular injections of relaxin showed a complete return to the normal range of motion (P < 0.01) when compared with the surgical control, whereas other delivery methods and frequencies failed to show meaningful improvements. This was further confirmed in histologic analysis through the lack of fibrotic adhesions within the capsular space after multiple intra-articular relaxin treatments when compared with the surgical control. DISCUSSION: Although significant improvements to range of motion were seen after multiple doses of intra-articular relaxin, potential tissue degradation was also observed within the joint space after histologic examination. Further research is necessary to fully understand the proper dosing needed to avoid potential negative side effects caused by excess use of relaxin
