    No full text
    Abstract The European Spallation Source (ESS) is a 5 MW, 2.5 MeV long pulse proton machine. It represents a big jump in power compare to the existing spallation facilities. The design phase is well under way, with the delivery of a Conceptual Design Report published in the beginning of 2012, and a Technical Design Report in December 2012. Why and how the 5 MW goal influences the parameter choices will be described

    Background The Epworth Sleepiness Scale (ESS [Johns MW. A new method for measuring daytime sleepiness: the Epworth sleepiness scale. Sleep 1991;14(6):540–5]) has been used frequently to assess daytime sleepiness, particularly in the context of clinical sleep disorders. Its psychometric properties are still unclear, particularly when used to evaluate sleep propensity in patients with obstructive sleep apnoea. Methods The present study used confirmatory factor analysis (CFA) to investigate a potential single-factor structure of the ESS in a sample of 759 Australian patients with a diagnosis of obstructive sleep apnoea by the treating physicians. Results CFA results from showed that the original single-factor structure proposed by Johns [Johns MW. Reliability and factor analysis of the Epworth Sleepiness Scale. Sleep 1992;15(4):376–81] did not adequately fit the data. A re-specified single-factor solution provided a good fit for data, and this improved fit was confirmed on a second CFA. Conclusions The findings suggest that standard scoring of the ESS should be interpreted cautiously for patients with obstructive sleep apnoea

    Falling through the (cultural) gaps?

    In this paper we report findings of a study of online participation by culturally diverse participants in a distance adult education course offered in Canada, and examine two of the study’s early findings. First, we explore both the historical and cultural origins of “cyberculture values” as manifested in our findings, using the notions of explicit and implicit enforcement of those values. Second, we examine the notion of “cultural gaps” between participants in the course and the potential consequences for online communication successes and difficulties. We also discuss theoretical perspectives from Sociolinguistics, Applied Linguistics, Genre and Literacy Theory and Aboriginal Education that may shed further light on “cultural gaps” in online communications. Finally, we identify the need for additional research, primarily in the form of larger scale comparisons across cultural groups of patterns of participation and interaction, but also in the form of case studies that can be submitted to microanalyses of the form as well as the content of communicator’s participation and interaction online

    Middle turbinate handling during ESS. Our experience

    No full text
    Purpose: The treatment of middle turbinate (MT) during endoscopic sinus surgery (ESS) for chronic rhinosinusitis (CRS) remains a controversial issue. Several authors recommended preservation of MT to avoid complications, but MT resection is sometimes necessary. In the last years, our group has applied an original surgical technique to preserve MT, stabilize its head and ensure patency of the ostiomeatal complex (OMC) in ESS. We herein described this approach to the MT and reported its preliminary results in terms of post-operative endoscopic features and complications. Methods: The study retrospectively considered 34 consecutive adult patients suffering from CRS and treated with primary or revision ESS. Medialization of the MT and its stabilization to achieve post-operative patency of the OMC was obtained by means of: (i) creation of a surgically controlled synechia between the MT head and nasal septum; (ii) positioning of a silicone plate in the OMC. The silicone splints kept the MT head in an obliged position to contact the septum. Results: At 12-month follow-up control, we found: (i) stabilized MT medialization in all treated cases, (ii) only one case of lateral synechia without recurrent CRS, and (iii) a polypoid recurrence rate of 13%. Conclusions: The MT handling technique during ESS herein preliminarily described seems to be an effective approach to medialize and stabilize the MT. This technique could be particularly appropriate for unstable MT after removing massive inflammatory lesions of the mucosa

    European Spallation Source Technical Design Report

    ESS, the European Spallation Source, will be a major user facility at which researchers from academia and industry will investigate scientific questions using neutron beams. Neutron methods provide insights about the molecular building blocks of matter not available by other means. They are used for both basic and applied research. ESS will be a slow neutron source of unparallelled power and scientific performance. It will deliver its first protons to a solid, rotating tungsten target in 2019, which will in turn generate neutrons for delivery to an initial suite of seven neutron scattering research instruments. ESS will reach its full design specifications in 2025, with a suite of 22 research instruments. The publication of the Technical Design Report in 2013 represents an important milestone for the ESS project, marking its readiness to move forward with construction activities. This executive overview provides a brief summary of the key insights and findings of the Technical Design Report

    Heterogeneity in ess transcriptional organization and variable contribution of the Ess/Type VII protein secretion system to virulence across closely related <em>Staphylocccus aureus </em>strains

    No full text
    The Type VII protein secretion system, found in Gram-positive bacteria, secretes small proteins, containing a conserved W-x-G amino acid sequence motif, to the growth medium. Staphylococcus aureus has a conserved Type VII secretion system, termed Ess, which is dispensable for laboratory growth but required for virulence. In this study we show that there are unexpected differences in the organization of the ess gene cluster between closely related strains of S. aureus. We further show that in laboratory growth medium different strains of S. aureus secrete the EsxA and EsxC substrate proteins at different growth points, and that the Ess system in strain Newman is inactive under these conditions. Systematic deletion analysis in S. aureus RN6390 is consistent with the EsaA, EsaB, EssA, EssB, EssC and EsxA proteins comprising core components of the secretion machinery in this strain. Finally we demonstrate that the Ess secretion machinery of two S. aureus strains, RN6390 and COL, is important for nasal colonization and virulence in the murine lung pneumonia model. Surprisingly, however, the secretion system plays no role in the virulence of strain SA113 under the same conditions

    The purpose of this study is to offer basic research for process oriented science curriculum through comparing and analyzing of ESS (Elementary Science Study) program developed early 1960&amp;apos;s and PKA (Physica1 Knowledge Activities) developed late 1970&amp;apos;s Concrete research questions are as follows: 1. What are theoretical backgrounds, aims, contents and methods of ESS? 2. What are theoretical backgrounds, aims, contents and methods of PKA? 3.What are the common points and the differences between ESS and PKA ? Research results of each question are as follows: First, ESS was based on piaget, Bruner theory and so on. That program put emphasis on longitudinal development and unit Which based on child interest. In the teaching method for ESS, teacher had the initiation on planned activity through teacher&amp;apos;s language. Second, PKA was based on piaget&amp;apos;s theory and put emphasis on lonyitudinal development and activity as to child interest. The teaching method for PKA was to construct Child&amp;apos;s knowledge for themselves though the direct activity with objects. Third, The common point and the differences of ESS and PKA appeared variously in its kind. ESS and PKA both emphasized the development of children in the educational purpose, and they focus on contents considering characteristics of a child&amp;apos;s interest and development in the substance. However the teacher in ESS used a teacher oriented teaching method while PKA used a child oriented teaching method.;본 연구는 1960년 초기에 개발된 ESS (Elementary Science Study) 프로그램과 1970년 후기에 개발된 PKA (Physical Knowledge Activities)를 비교 분석함으로써 과정중심의 과학교육에 기초자료가 되고자 하는데 목적이 있다. 구체적인 연구문제는 다음과 같다. 1. ESS의 이론적 근거, 교육목적 및 목표, 교육내용, 교육방법은 무엇인가? 2. PKA의 이론적 근거, 교육목적 및 목표, 교육내용, 교육방법은 무엇인가? 3. ESS와 PKA의 이론적 근거, 교육목적 및 목표, 교육내용, 교육방법에 있어서 공통점과 차이점은 무엇인가? 연구문제에 따른 연구의 결과는 다음과 같다. 첫째, ESS는 Piaget, Bruner등의 이론에 근거하였으며, 장기적인 발달의 목적을 강조하였다. 또한 아동의 흥미에 기초한 단원을 교육내용으로 하였다. ESS는 교사가 계획한 활동을 아동이 실행하도록 언어적으로 유도하는 교사중심의 교수방법을 사용하였다. 둘째, PKA는 Plaget의 이론에 근거하였으며, 장기적인 발달의 목적을 강조하였다. 또한 아동의 흥미에 기초한 활동을 교육내용으로 하였다. PKA는 아동 스스로 물체와의 직접적인 행위를 통해 지식을 구성해 나가는 아동중심의 교수방법을 사용하였다. 세째, ESS와 PKA의 공통점과 차이점은 이론적 근거, 교육목적 및 목표, 교육 내용, 교육 방법에 따라 다양하였다. 그 전체적인 경향은 다음과 같았다. 즉 ESS와 PKA는 교육목적에 있어서 공통적으로 아동의 흥미와 발달의 특징을 고려하여 내용을 선정하였다. 그러나 방법에 있어서 ESS는 교사가 계획한 활동을 하도록 유도 하는 교사중심의 교수방법을 사용하는 반면 PKA는 아동이 활동을 계획하고 실행하는 아동중심의 교수방법을 사용하는 차이점이 있었다.목차 = ⅲ 논문개요 = ⅵ Ⅰ. 서론 = 1 A. 연구의 필요성 및 목적 = 1 B. 연구문제 = 4 C. 연구방법 = 4 Ⅱ.

    Diffusive author(s), cohesive author: Analysis of S/N (1994)

    No full text
    This study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)

    No full text
    Objectives: The aim of this controlled follow-up study was to compare the need for revision surgery, long-term efficacy, and satisfaction in chronic rhinosinusitis patients who had undergone maxillary sinus operation with either balloon sinuplasty or traditional endoscopic sinus surgery (ESS) technique. Methods: Thirty-nine ESS patients and 36 balloon patients of our previously described cohort, who had been primarily operated in 2008 to 2010, were contacted by phone. Symptoms, satisfaction, and need for revision surgery were asked. In addition, we collected data of patients who had undergone primary maxillary sinus balloon sinuplasty in the Helsinki University Hospital during the years 2005 to 2019. As a control group, we collected data of patients who had undergone primary maxillary sinus ESS at 3 Finnish University Hospitals, and 1 Central Hospital in years 2005, 2008, and 2011. Results: Altogether, 77 balloon patients and 82 ESS patients were included. The mean follow-up time was 5.3 years in balloon group and 9.8 years in ESS group. Revision surgery was performed on 17 balloon patients and 6 ESS patients. In the survival analysis, the balloon sinuplasty associated significantly with a higher risk of revision surgery compared to ESS. According to the phone interviews, 82% of ESS patients and 75% of balloon patients were very satisfied with the primary operation. Conclusion: Although the patient groups expressed equal satisfaction and change in symptoms after the operations, the need for revision surgery was higher after balloon sinuplasty than after ESS. This should be emphasized when counselling patients regarding surgical options.Peer reviewe
