Analysis of Energy Saving Effect of Solar Light Pipe Systems in Beijing Olympic Buildings

In response to the concept of Olympics, Beijing Olympic buildings use solar light pipe systems for daylighting, such as the underground passage in the Olympic Forest Park and the gymnasium of University of Science and Technology Beijing. In this paper, the solar light pipe systems in the two buildings have been measured to find out whether indoor daylighting performance can meet daily use requirements. At last, compare the result with T8 fluorescent lamps to get the energy saving effect of two buildings. Calculating results showed that indoor illuminance of the two buildings can achieve daily use requirements when external illuminance reaches 25036lx and17895lx, and the amount of electricity that can be saved are 2514KW•h and 22186KW•h per year.

Oseltamivir Compared With the Chinese Traditional Therapy Maxingshigan–Yinqiaosan in the Treatment of H1N1 Influenza

Observational studies from Asia suggest that maxingshigan-yinqiaosan may be effective in the treatment of acute H1N1 influenza. To compare the efficacy and safety of oseltamivir and maxingshigan-yinqiaosan in treating uncomplicated H1N1 influenza. Prospective, nonblinded, randomized, controlled trial. (ClinicalTrials.gov registration number: NCT00935194) Eleven hospitals from 4 provinces in China. 410 persons [corrected] aged 15 to 69 [corrected] years with laboratory-confirmed H1N1 influenza. Oseltamivir, 75 mg twice daily; maxingshigan-yinqiaosan decoction (composed of 12 Chinese herbal medicines, including honey-fried Herba Ephedrae), 200 mL 4 times daily; oseltamivir plus maxingshigan-yinqiaosan; or no intervention (control). Interventions and control were given for 5 days. Primary outcome was time to fever resolution. Secondary outcomes included symptom scores and viral shedding determined by using real-time reverse transcriptase polymerase chain reaction. Significant reductions in the estimated median time to fever resolution compared with the control group (26.0 hours [95% CI, 24.0 to 33.0 hours]) were seen with oseltamivir (34% [95% CI, 20% to 46%]; P < 0.001), maxingshigan-yinqiaosan (37% [CI, 23% to 49%]; P < 0.001), and oseltamivir plus maxingshigan-yinqiaosan (47% [CI, 35% to 56%]; P < 0.001). Time to fever resolution was reduced by 19% (CI, 0.3% to 34%; P = 0.05) with oseltamivir plus maxingshigan-yinqiaosan compared with oseltamivir. The interventions and control did not differ in terms of decrease in symptom scores (P = 0.38). Two patients who received maxingshigan-yinqiaosan reported nausea and vomiting. Participants were young and had mild H1N1 influenza virus infection. Missing viral data precluded definitive conclusions about viral shedding. Oseltamivir and maxingshigan-yinqiaosan, alone and in combination, reduced time to fever resolution in patients with H1N1 influenza virus infection. These data suggest that maxingshigan-yinqiaosan may be used as an alternative treatment of H1N1 influenza virus infection. Beijing Science and Technology Project and Beijing Nova Program.

Editorial

Dear Reader, Welcome to the latest issue of Steel Research International. Our journal entered 2011 in great health: The number of submissions we receive each year is steadily increasing, the overall quality of submissions remains very high, our journal is supported by an enthusiastic editorial board representing the top institutes, societies and manufacturers in the world of steel, and it features a robust infrastructure provided by Wiley-VCH, including online access via Wiley's new portal for journals and books, Wiley Online Library. But the good news does not stop there. This month we'd like to let you know about the most recent developments going on in our journal, and some indications of yet more good news to come. Following its long history of publishing as Archiv für das Eisenhüttenwesen and now as Steel Research International, our journal is, as of this year, managed by a dedicated, full-time team of professional editors based in Wiley-VCH's Weinheim office in south-west Germany. This same team is also responsible for leading high Impact Factor materials science journals such as Advanced Materials and the materials science news portal materialsviews.com Therefore, when you submit your work, you can expect to receive a quality service worthy of a high Impact Factor journal, and for your best work to be promoted to a very large interdisciplinary audience of materials scientists, physicists, chemists and engineers. Speaking of which, our journal now holds a monthly “Editor's Choice” award for the best paper published in each issue. The choice of the award is based on highly positive reviewer reports, anticipation of widespread interest amongst our readership, and exceptional scientific quality. The Editor's Choice paper will be highlighted in the table of contents, receive coverage on materialsviews.com, and the corresponding author will receive a certificate. Will your next submission be picked for the Editor's Choice? We began 2011 with two special issues: Issue 1 highlighted the hot topics discussed at the Materials Science and Engineering (MSE) conference in Darmstadt last year, while Issue 2 focused on ab initio techniques in steel research. We will continue to focus on important events and topical developments in steel research and related disciplines around the world, and we look forward to meeting you out and about. Looking at the most downloaded articles from last year (see below), the international appeal and broad scope of Steel Research International is readily apparent. Papers from the traditional European and Scandinavian strongholds for steel making and research are present in the Top 10, alongside contributions from two countries that are now strongly associated with steel production: India and Brazil. Japan and Korea would also be conspicuous by their absence from any list of Top 10 steel research papers, and we are enthusiastically developing our ties with metallurgists in Asia, for example by our association with the Chinese Society for Metals (pictured). Having got off to a great start in 2011, we are looking forward to developing the journal even more and engaging with you to report the most important developments in steel and related materials, wherever they may be occurring. We very much appreciate the continuing input and enthusiasm of our Editorial Board and Advisory Board, and for the great efforts of our authors and peer reviewers for their important contributions. Of course, if you have any comments, suggestion or questions for our journal, please just let us know; we'd be happy to hear from you.

Application of High Power DC Arc Plasma for Mass Production of High Quality Freestanding Diamond Films and Diamond Film Coated Cutting Tools

As quasi-thermodynamic equilibrium plasma, DC Arc Plasma has the advantage of very high gas temperature and thus the very high degree of activation of the precursors for diamond film deposition. The present paper reviews the progresses in the R&amp;D of the novel high power dc arc plasma jet CVD system with rotating arc and operated at gas recycling mode for large area high quality diamond film deposition, developed at the University of Science and Technology Beijing (USTB) in the mid 1990s of the 20th century. Thanks to the continuous efforts made in the technological improvement in the past 15 years, considerable progresses have been achieved in the commercialization of this high power dc arcjet CVD system, which is now capable of mass production of large area high quality freestanding diamond films for optical, thermal, and mechanical (tool) applications. The present status in the commercialization and the property level of the resultant diamond films in optical, thermal, mechanical, dielectric, oxidation resistance, sand erosion resistance, and laser damage threshold etc. are presented. Based on the same high power dc arcjet technology, a novel high current extended dc arc plasma (HCEDCA) CVD system has been developed which successfully changed the diamond film deposition mode from 2D planar deposition in to 3D deposition (as confined by two hollow (virtue) columns). It is demonstrated to be advantageous for mass production of diamond thin film coated WC-Co cutting tools. Recent results in the R&amp;D of thin diamond film coated WC-Co drills and end mills, and the results in field tests are discussed.

Status of R&D on fusion materials in institute of nuclear materials in USTB

Materials constitute a key issue on the path to fusion power reactors. In recent years, activities on materials for fusion reactors are focused on plasma-facing materials, low activation structural materials and functional materials in the Institute of Nuclear Materials, University of Science and Technology Beijing (USTB). Through more than 10-year research the plasma-facing materials including SiC/C, B 4C/C, SiC/Cu, B 4C/Cu, and W/Cu functionally graded materials (FGMs) have been developed and new progress on ultra-fine grained tungsten is reported. The functional materials mainly focus on lithium ceramic-type tritium breeders. Researches on low activation structural materials are focused on enhancing the elevated temperature performance. The paper is aimed at presenting the main achievements obtained, key issues and the near- and mid-term perspectives on the fusion materials investigated in the Institute of Nuclear Materials, USTB.

Hepatoblastoma in Adult: Review of the Literature

This study is to review and retrieve data on adult hepatoblastoma (HB) from English literatures in order to gain a better understanding of this disease. We performed Medline, PubMed (from January 1966 to February 2008), and library searches (National Science and Technology Library, Beijing, China, and Wenzhou Medical College Library, from January 1980 to February 2008) using the key words hepatoblastoma in adult, hepatic tumor, hepatoblastoma and adult. Previously reported HB cases were collected and published reviews were also examined. Fifteen cases that met the search criteria were selected. Review of the cases revealed a slight female preponderance. The patients' age ranged from 17 to 82, with median age of 70 for male and 27 for female. The survival time ranged from two weeks to 38 months, and the median survival time was 6 months. In the articles reviewed, HB presented with non-specific initial symptoms, and the diagnosis was not identified until the tumor biopsy after operation or autopsy. Completely surgical resection is still the major treatment for patients with HB and is considered as the only chance of a better prognosis. Due to the rareness of HB in adults, the choice of treatment should be radical resection if possible, and combined with chemotherapy as adopted in children. HB in the adult is extremely rare and the pre-operative diagnosis is often overlooked. The prognosis is so poor that the awareness of the condition in the differential diagnosis in liver tumors could be beneficial.Key wordsHepatoblastoma; Adult; Diagnosis; Therapy

Mechanism of low thermal conductivity of xonotlite-silica aerogel nanoporous super insulation material

In an effort to incorporate the low thermal conductivity of the silica aerogel and the superior structure strength of the xonotlite, a composite material of these two was produced. It was synthesized under vacuum condition and dried by supercritical drying technique. The thermal conductivity of the new material, which is at 298 K with the gas pressure ranging from 1.01×10 5 to 1×10 − 2 Pa, was measured using the transient hot-strip method. The mechanism of the low thermal conductivity was studied. The results indicate that the low thermal conductivity mainly results from the significant decrease of gaseous thermal conductivity of the new material due to the restriction of the motion of gas molecules in its fine structures. The formation of the fine structures is because the new material takes the pore structure of the silica aerogel which consists of mainly nanometer-sized pores. © 2008 University of Science and Technology Beijing.
