Doubly transitive lines II: Almost simple symmetries

We study lines through the origin of finite-dimensional complex vector spaces that enjoy a doubly transitive automorphism group. This paper, the second in a series, classifies those lines that exhibit almost simple symmetries. To perform this classification, we introduce a general recipe involving Schur covers to recover doubly transitive lines from their automorphism group

Role of Metallurgical Pilot Plants in the United States

The large capital costs of metallurgical plants and rapidly advancing metallurgical technology have forced industry in the United States to rely increasingly on demonstration or pilot-plant investigations to minimize the risk of economic or technical.failure of new install-ations. This commonly accepted use, which has been discussed frequently in technical journals, arises from several causes . Among these are the growing dependence on lower-grade ores or different types of ores than have been previously used, and on the increasing per-capita consumption, of nearly all metals and metal-bearing products. Other reasons are the advent of new metall-urgical processes , the need for new or higher quality products, and the availability of better equipment

Electronic health information and long term conditions

This article discusses the increasing availability of health-related information, and the impact that this can have for people with long-term conditions’ expectations of healthcare providers. The article suggests a framework for decision making about the role that healthcare staff should play in the information searching, retrieval, and synthesis activities which people with long-term conditions engage in. The framework is based on a series of decisions related to: perceptions of ownership of long-term conditions; whether intermediatory or apomediatory approaches to information management are deemed to be most appropriate; and, as a result of these considerations, what, if any, place healthcare staff should take in the process of patients searching or and interpreting information about long-term health needs. These decisions will enable healthcare providers to plan services based on clear decision pathways, and to clarify to all concerned what are deemed to be reasonable expectations of health service provision

The role of internet resources in health decision-making::a qualitative study

Objective: Internet resources remain important for health information and advice but their specific role in decision-making is understudied, often assumed and remains unclear. In this article, we examine the different ways in which internet resources play a role in health decision-making within the context of distributed decision-making. Methods: We conducted semi-structured interviews with thirty-seven people in the United Kingdom who reported using the internet in relation to decision-making and represented a range of long and short-term health conditions. The interviews focused on decision-making activities across different settings and in relation to different stakeholders to understand how internet resources play a role in these activities. We carried out a thematic analysis of the interviews. Results: We identified three main ways in which internet resources played a role in health decision-making. A supportive role (as a decision crutch), a stimulating role (as a decision initiator), and an interactional role (impacting on the doctor–patient relationship). These three roles spanned different resources and illustrated how the decision-making process can be impacted by the encounters people have with technology – specifically internet based health resources, in different ways and at different time points. Conclusions: Examining health decisions in respect to internet resources highlights the complex and distributed nature of decision-making alongside the complexity of online health information sourcing. We discuss the role of internet resources in relation to the increasing importance of online personal experiences and their relevance within shared decision-making

System for determining position of normal shock in supersonic flow

Light from a plurality of light emitting diodes is transmitted through optical cables (12) to a lens system. The lenses (56, 58) expand and collimate the light and project it in a sheet (16) across the supersonic inlet of an aircraft power plant perpendicular to incoming airflow. A normal shock bends a portion of the sheet of light (16). A linear array of a multiplicity of optical fiber ends collects discrete samples of light. The samples are processed and compared to a predetermined profile to determine the shock location
