Space station thermal control surfaces

Mission planning documents were used to analyze the radiator design and thermal control surface requirements for both space station and 25-kW power module, to analyze the missions, and to determine the thermal control technology needed to satisfy both sets of requirements. Parameters such as thermal control coating degradation, vehicle attitude, self eclipsing, variation in solar constant, albedo, and Earth emission are considered. Four computer programs were developed which provide a preliminary design and evaluation tool for active radiator systems in LEO and GEO. Two programs were developed as general programs for space station analysis. Both types of programs find the radiator-flow solution and evaluate external heat loads in the same way. Fortran listings are included

Digital-enabled service transformation in public sector: Institutionalization as a product of interplay between actors and structures during organisational change

The derailment of large scale Digitally-Enabled Service Transformation Projects (DEST) in public sector has generated much attention and debate among the research community. However, most of the debates focus on the technology imperatives and/or strategic choices view. The micro-process of institutionalisation involving interplays between actors and structures in forming an institutionalised approach is hardly brought to the surface. Complex structure of government institutions, interaction of actors from various contexts and integration of multiple resources during DEST implementation has made the process of institutionalisation difficult. Combination of Institutional Theory (IT) and Structuration Theory (ST) concepts are used in this paper to examine an exemplar DEST project in the UK - 'Tell Us Once' (TUO). Findings show that actors and structures played significant roles throughout the institutionalisation stages. The actors reinforced or modified existing structures to suit their actions, and in return, the structure governed the actors' actions, to form desired behaviour. This social phenomenon happened recursively over period of time until a common practice emerged and the desired objective is achieved. The findings provide useful insights on good institutionalisation practices concerning the role of actors and structures within the institutionalisation process

A system for patient management based discrete-event simulation and hierarchical clustering

Hospital Accident and Emergency (A&E) departments in England have a 4 hour target to treat 98% of patients from arrival to discharge, admission or transfer. Managing resources to meet the target and deliver care across the range of A&E services is a huge challenge for A&E managers. This paper develops an intelligent patient management tool to help managers and clinicians better understand patient length of stay and resources within an A&E area. The developed discrete-event simulation model gives a highlevel representation of ambulance arrivals into A&E. The model facilitates analysis in the following ways: visually interactive software showing patient length of stay in the A&E area; patient activity broken down into sub-groups so that intelligence might be gathered on how sub-groups affect the overall length of stay; understanding the number of patient treatment places and nurse resources required. To support ease of inputs for scenario and sensitivity testing, data is entered into the simulation model (Simul8) via Excel spreadsheets. The model discussed in this paper used patient length of stay grouped by A&E diagnosis codes and was limited to ambulance arrivals. The analysis was derived from A&E attendance in 2004 from an English hospital

A study of the perceived causes of schism in some Ethiopian-type churches in the Cape and Transvaal, 1884-1925

During the period 1884-1925 Ethiopian-type schisms from mission churches occurred for a number of reasons. Generalisations of these reasons have been made by numerous authors. By generalising the causes of schism the particular reasons why each independent church 1 eader 1 eft the mission church are ignored. The thesis shows how each schism was due to unique circumstances in the mission church as well as to factors, for example, the personal feelings of the independent church leader. In each case there was a point of no return when the founder of the independent church no longer felt he could accept the status quo. There were two government commissions that investigated the independent or "separatist" churches during these years - the South African Native Affairs Commission of 1903-1905 and the 1925 South African Native Affairs Commission which investigated the "Separatist Churches". The testimony of the white government officials and missionaries and the black church leaders has been compared with the findings in the reports. Four case studies are investigated to show how general causes of schism may occur for a number of years until a reason, peculiar to the particular independent church, manifests itself and leads to the formation of an independent church. The case studies are the Ethiopian Church and related independent groups, the independent churches which joined the African Methodist Episcopal Church in 1896 with the Ethiopian Church but later left to form their own churches, for example the Order of Ethiopia, schisms from the Presbyterian Church during the 1890' s and the Independent Methodist Church.Christian, Spirituality, Church History and MissiologyD.Th (Church History

What do children who stutter and their parents expect from therapy and are their hopes aligned?

Currently there are few published reports exploring what it is that children and their parents wish to see change or happen as part of therapy. A process of eliciting hopes or expectations for therapy using Solution Focused Brief Therapy (de Shazer, 1985) is routinely used at the Michael Palin Centre (MPC) with children who stutter and their parents. This qualitative study aimed to explore what children who stutter and their parents expect from therapy and whether their hopes are aligned

Explorations in anatomy: the remains from Royal London Hospital

This paper considers the faunal remains from recent excavations at the Royal London Hospital. The remains date to the beginning of the 19th century and offer an insight into the life of the hospital's patients and practices of the attached medical school. Many of the animal remains consist of partially dissected skeletons, including the unique finds of Hermann's tortoise (Testudo hermanni) and Cercopithecus monkey. The hospital diet and developments in comparative anatomy are discussed by integrating the results with documentary research. They show that zooarchaeological study of later post-medieval material can significantly enhance our understanding of the exploitation of animals in this perio

An Intelligent Advisor for City Traffic Policies

Nowadays, city streets are populated not only by private vehicles but also by public transport, fleets of workers, and deliveries. Since each vehicle class has a maximum cargo capacity, we study in this article how authorities could improve the road traffic by endorsing long term policies to change the different vehicle proportions: sedans, minivans, full size vans, trucks, and motorbikes, without losing the ability of moving cargo throughout the city. We have performed our study in a realistic scenario (map, road traffic characteristics, and number of vehicles) of the city of Malaga and captured the many details into the SUMO microsimulator. After analyzing the relationship between travel times, emissions, and fuel consumption, we have defined a multiobjective optimization problem to be solved, so as to minimize these city metrics. Our results provide a scientific evidence that we can improve the delivery of goods in the city by reducing the number of heavy duty vehicles and fostering the use of vans instead.Universidad de Málaga.

Settlement and landscape development in the Homs Region, Syria: research questions, preliminary results 1999-2000 and future potential

This report describes the results of the first and second seasons of field work by an interdisciplinary research team studying the landscape history of the upper Orontes Valley near Homs in western Syria. Initial discussions address the value of survey data to Syrian archaeology, the research aims of the project and describe the survey area. The project methodology, which includes a combination of both extensive and intensive survey methods, is outlined, and the use of satellite imagery as a means of site location discussed. Work on geomorphological processes and off-site artefact distributions has facilitated the development of sampling strategies for intensive surface collection planned for 2002 and 2003. A test core has established that pollen is well-preserved in the silts of Lake Qattine, which appear to offer a west Syrian palaeoenvironmental sequence. Preliminary work in the basalt terrain west of Homs has allowed the refinement of methodologies for the mapping and analysis of cairns and field systems which predominate in this area, and has highlighted the threat resulting from current bulldozing. The report concludes with some preliminary observations on the main trends as these are emerging from the data

Ozone loss derived from balloon-borne tracer measurements in the 1999/2000 Arctic winter

Balloon-borne measurements of CFC11 (from the DIRAC in situ gas chromatograph and the DESCARTES grab sampler), ClO and O3 were made during the 1999/2000 Arctic winter as part of the SOLVE-THESEO 2000 campaign, based in Kiruna (Sweden). Here we present the CFC11 data from nine flights and compare them first with data from other instruments which flew during the campaign and then with the vertical distributions calculated by the SLIMCAT 3D CTM. We calculate ozone loss inside the Arctic vortex between late January and early March using the relation between CFC11 and O3 measured on the flights. The peak ozone loss (~1200ppbv) occurs in the 440-470K region in early March in reasonable agreement with other published empirical estimates. There is also a good agreement between ozone losses derived from three balloon tracer data sets used here. The magnitude and vertical distribution of the loss derived from the measurements is in good agreement with the loss calculated from SLIMCAT over Kiruna for the same days
