Beam Drift Chamber (BDC) is designed to reconstruct the trajectories of incident rare isotope beams provided by RAON (Rare isotope Accelerator complex for ON-line experiments) into the experimental target of LAMPS (Large Acceptance Multi-Purpose Spectrometer). To conduct the performance test of the BDC, the prototype BDC (pBDC) is manufactured and evaluated with the high energy ion beams from HIMAC (Heavy Ion Medical Accelerator in Chiba) facility in Japan. Two kinds of ion beams, 100 MeV proton, and 200 MeV/u 12C, have been utilized for this evaluation, and the track reconstruction efficiency and position resolution have been measured as the function of applied high voltage. This paper introduces the construction details and presents the track reconstruction efficiency and position resolution of pBDC.
A new radioactive ion-beam accelerator facility, RAON, is under construction in Korea. Among the seven experimental systems being built, the Large Acceptance Multi-Purpose Spectrometer (LAMPS) in the highenergy experimental hall is the versatile detector system for nuclear physics. Its primary goal is to study the nuclear equation of state (EoS) and the symmetry energy of the compressed nuclear matter, which should be essential to understand the effective nuclear interactions and structure of the astrophysical objects like neutron stars. The basic LAMPS system consists of the beam diagnostic elements such as the starting counters and beam drift chambers, the time-projection chamber, the barrel and forward time-of-flight systems, the forward neutron detector array, and the superconducting solenoid magnet. In this paper the overview of the present status of each detector component for LAMPS will be given with some prospects.
A direct cross-section measurement of the 14O(α,p)17F reaction is important to understand the light curves of x-ray bursts. The measurement will be performed using the Texas Active Target TPC version 2 (TexAT_v2). The TexAT_v2 aims at measuring lower energy protons from the reaction than the original TexAT. Newly developed silicon and CsI(Tl) detector arrays are added at the left, right and bottom of a modified field cage to increase its detection efficiency. This paper describes the overall specifications and two commissioning experiments performed at Texas A&M University.
Incidence of ovarian pregnancy is rare (1/3000 to 1/50000 deliveries) and 3% of total ectopic pregnancies by natural conception. There are many reasons of ectopic pregnancy, mostly arise in using of IUD and ART. Prediagnosis of ovarian pregnancy is not easy and 28% of the cases are possible to diagnosis during the surgery, because it's findings are likely to mimic those of a tubal pregnancy or an ovary cyst rupture. If you don't get the serum beta HCG result, definitely it is suspected during surgery and confirmed by histopathology. Massive ovarian bleeding is also seen in one third of cases. The 33-year-old primi gravida with amenorrhea 6 weeks Presented. When she came to ER, she suffered frompain and vital signs were unstable; BP = 90/60mmHg, Pulse = 116/min. Serum beta HCG levels was 4907 IU/L and transvaginal USG showed no G-sac in uterine cavity and only a cyst with a wide ecogenic outer ring existed on right adnexa measuring 23 mm × 23 mm, suggestive of ectopic focus. The patient was taken for laparoscopic surgery. The right ovary was appeared to be ruptured with hemoperitoneum (amount 400ml). Single port laparoscopic excision was done and specimen was come out villous tophoblasts by histopathology. Single port laparoscopy is widely used because of the minimised potential morbidity and maximised cosmetic benefits compared to conventional Laparoscopy. Despite the advantages of Single port laparoscopy, unstable vital signs with massive hemoperitoneum are frequently avoided as contraindications. However, we performed successful diagnostic single port laparoscopy as convention. Patient's initial hemoglobin was 8.4 gm/dl. And after 2 PRC transfusion no more hemodiluted condtion was seen until end of the hospitalisation.

Entecavir (ETV) has been shown to be safe and efficacious in randomised controlled trials in highly selected patients with hepatitis B virus (HBV) infection.To determine the safety and effectiveness of ETV in 'real-world' HBV patients in the United States (US).Treatment-naïve HBV patients ≥18 years old who received ETV for ≥12 months between 2005 and 2013 were included in a retrospective, cohort study. Rates of ALT normalisation, undetectable HBV DNA, HBeAg and HBsAg loss/seroconversion, adverse events (AE) and clinical outcomes were evaluated.Of 841 patients, 658 [65% male, 83% Asian; median age 47 years] met the inclusion criteria. 36% were HBeAg+ and 9.3% cirrhotic. 89% had abnormal ALT. Baseline median HBV DNA was 5.8 log 10 IU/mL. Median duration of ETV treatment was 4 years. Rates of ALT normalisation at 1, 3 and 5 years were 37.2%, 48.7% and 56.2% in HBeAg+ and 39.6%, 46.8% and 55.6% in HBeAg- patients. HBV DNA was undetectable at 1, 3 and 5 years in 34.6%, 64.7% and 84.6% in HBeAg+ patients, and 81.9%, 90.3% and 96.2% in HBeAg patients. Five-year cumulative probability of HBeAg loss and seroconversion was 46% and 33.7% and HBsAg loss was 4.6%. ETV was discontinued due to adverse events in 1.2% of patients. Hepatic decompensation occurred in 0.8%, liver cancer in 2.7% and death in 0.6%.Entecavir treatment was safe in a large cohort of US patients, but ALT normalisation and hepatitis B virus DNA suppression rates were lower than previously reported in clinical trials.

This paper presents the preliminary results from an analysis of the energy saving potential in new and existing Texas Independent School Districts (ISDs). The analysis was performed using a K-12 simulation model based on the DOE-2.1e program that uses ASHRAE Standard 90.1 code-compliant, school buildings for three climate zones in Texas. In this analysis, government and private data sources from the U.S. EPA Energy Star, the Texas Education Agency, and the EnergyPlus Benchmark school models were reviewed to determine the base-case K12 school characteristics in Texas. Available guidelines and case-studies were reviewed to develop energy efficient measures for high performance school buildings. As a result, four base-case school models that are compliant with the ASHRAE Standard 90.1-1989, 1999, 2004, and 2007 were developed for each climate zone. In addition, a total of eighteen energy efficient measures were considered. These include measures for the building envelope, lighting, HVAC system, DHW system, and renewable energy systems. The proposed energy efficient measures were then applied to the base-case school model to examine the energy saving potential for Texas ISDs. INTRODUCTION Schools are one of the building types with a high energy saving potential from the application of high performance strategies. The most efficient schools use one third the energy than the least efficient schools (EPA 2010). Im and Haberl (2006) reviewed over fifty studies on existing high performance schools. From this review, the annual energy savings from the application of high performance strategies ranged from 20% to 40%. However, to maximize the savings from high performance applications, it is obvious that different strategies are needed for schools built in different years as well as different climate zones. According to the survey of Texas Comptroller of Public Accounts (2006), the average age of Texas elementary, middle, and high schools is 35.2, 32.2, and 32.7 years old, respectively. In addition, the average enrollment of Texas public schools continuously increased over the past 10-year period by 20.1% (TEA 2009). This would indicate that there is a huge energy saving potential in both existing and new schools in Texas from the application of high performance retrofit strategies. This paper presents the preliminary results from an analysis of the energy saving potential in new and existing Texas Independent School Districts (ISDs). The analysis was performed using a K-12 simulation model based on the DOE-2.1e program that uses ASHRAE Standard 90.1 code-compliant, school buildings for three climate zones in Texas according to ASHRAE 90.1-2004 and 2007 climate zone classifications. METHODOLOGY Figure 1 shows the detailed procedure for calculating the potential energy savings for existing K-12 schools in Texas. In this analysis, the existing K-12 schools were classified as three school groups according to the year of construction as Group 1: schools built before 2000; Group 2: schools built between 2000 and 2007; and Group 3: schools built after 2007. To calculate potential energy savings for new high performance K-12 schools in Texas, new schools that will be constructed in 2011 were classified as Group 4, and the total floor area (sq. ft.) of new schools will be estimated using the population growth rate. For the baseline of new schools, ASHRAE Standard 90.1-2007 requirements were referenced. To estimate the savings of all the schools of Texas, simulations for every school in each county should be carried out, which would lead to an extraordinary number of simulations. To simplify the calculation procedure, different counties in Texas were grouped according to ASHRAE 90.1-2004 and ESL-HH-10-08-19

The Energy Systems Laboratory was requested to develop cost-effective recommendations to maximize energy savings for residential and commercial buildings in the City of Arlington (CoA). This report presents the analysis results for small retail buildings in the CoA. For more realistic recommendations, the CoA provided two years of commercial building energy compliance reports from 2008 to 2010 which exceeded the energy efficiency requirements of the CoA (i.e., ASHRAE 90.1-2001). From a statistical analysis of energy compliance reports provided for eleven commercial, above-code approaches that had been made in the CoA were summarized for commercial applications 1. Based on a summary of above-code approaches, recommendations were developed to achieve above-code energy performance based on the ASHRAE 90.1-2001 and 2007 standard reference buildings, for small retail buildings in the CoA The deliverables for the CoA in this report are: • Recommendations of 16 energy efficiency measures (EEMs) to maximize energy savings for small retail buildings in the CoA with estimated cost of the improvement, simple payback calculations, and emissions savings. A total of 16 recommendations based on the energy savings above the base-case building were selected. These measures include building envelope and fenestration, HVAC system, service hot water (SHW) system, lighting, and renewable options. The implementation costs of each individual measure were also calculated along with simple payback calculations. Figures 1 and 2 present a description of the individual measures and combinations of these measures which achieve 15% source energy savings above the ASHRAE 90.1-2001 and 2007 code-compliant building. Annual energy savings, estimated costs, simple payback, and NOx, SO 2 , and CO 2 emissions reduction are provided.

In August 2004, the USEPA issued guidance on quantifying the air emission benefits from electric sector energy efficiency and renewable energy. Because there was no clear best strategy, the EPA's guidance provided a framework and the basic requirements needed to demonstrate air quality improvements or emission reductions with adequate certainty to be incorporated into a State Implementation Plan (SIP) for achieving or maintaining National Ambient Air Quality Standards (NAAQS). The Energy Systems Laboratory, with guidance from both the US EPA and the Texas Commission on Environmental Quality (TCEQ), developed the first comprehensive engineering toolkit and database that satisfies the EPA guidelines. The value of this unique tool was demonstrated in 2005 when the Energy Systems Laboratory (ESL), at the request of the TCEQ, used it to develop integrated emissions estimates for all state agencies participating in the Texas Emissions Reduction Plan (TERP). Building on this expertise, the US EPA has established a National Center of Excellence on Displaced Emission Reductions (CEDER) at the Energy Systems Laboratory to research and gather the state-of-the-art on air pollution quantification techniques for Energy Efficiency / Renewable Energy (EE/RE) projects; provide technical support and customized analysis for state and local agencies seeking to estimate the environmental benefits from clean energy policies and programs; and to document how a user-friendly tool, based on e2Calc, can be used by clients to fulfill their needs to quantify emission reductions from energy efficiency and renewable energy measures. The report is organized in several deliverables: • Summary Report, which details the progress of tasks; • Appendix, which shows the survey documentation, screenshots of emissions calculators, and screenshots …
Kennedy’s disease is a rare lower motor neuron disease affecting the limbs and bulbar musculature. Regional anesthesia is generally the recommended anesthetic technique in patients with Kennedy’s disease because of bulbar involvement and airway clearing disturbance. We administered general anesthesia in a patient with Kennedy’s disease who was undergoing a laparoscopic cholecystectomy. We closely monitored the degree of neuromuscular blockade throughout the operation and injected atracurium on demand. There was no exacerbation of neurologic signs or symptoms postoperatively. Therefore, we report the successful administration of general anesthesia for laparoscopic cholecystectomy in a patient with Kennedy’s disease.
