Study of vapor flow into a capillary acquisition device

An analytical model was developed that prescribes the conditions for vapor flow through the window screen of a start basket. Several original submodels were developed as part of this model. The submodels interrelate such phenomena as the effect of internal evaporation of the liquid, the bubble point change of a screen in the presence of wicking, the conditions for drying out of a screen through a combination of evaporation and pressure difference, the vapor inflow rate across a wet screen as a function of pressure difference, and the effect on wicking of a difference between the static pressure of the liquid reservoir and the surrounding vapor. Most of these interrelations were verified by a series of separate effects tests, which were also used to determine certain empirical constants in the models. The equations of the model were solved numerically for typical start basket designs, and a simplified start basket was constructed to verify the predictions, using both volatile and nonvolatile test liquids. The test results verified the trends predicted by the model

New technologies for urban designers: the VENUE project

In this report, we first outline the basic idea of VENUE. This involves developing digital tools froma foundation of geographic information systems (GIS) software which we then apply to urbandesign, a subject area and profession which has little tradition in using such tools. Our project wasto develop two types of tool, namely functional analysis based on embedding models of movementin local environments into GIS based on ideas from the field of space syntax; and secondlyfashioning these ideas in a wider digital context in which the entire range of GIS technologies werebrought to bear at the local scale. By local scale, we mean the representation of urban environmentsfrom about 1: 500 to around 1: 2500

GIS and urban design

Although urban planning has used computer models and information systems sincethe 1950s and architectural practice has recently restructured to the use of computeraideddesign (CAD) and computer drafting software, urban design has hardly beentouched by the digital world. This is about to change as very fine scale spatial datarelevant to such design becomes routinely available, as 2dimensional GIS(geographic information systems) become linked to 3dimensional CAD packages,and as other kinds of photorealistic media are increasingly being fused with thesesoftware. In this chapter, we present the role of GIS in urban design, outlining whatcurrent desktop software is capable of and showing how various new techniques canbe developed which make such software highly suitable as basis for urban design.We first outline the nature of urban design and then present ideas about how varioussoftware might form a tool kit to aid its process. We then look in turn at: utilisingstandard mapping capabilities within GIS relevant to urban design; buildingfunctional extensions to GIS which measure local scale accessibility; providingsketch planning capability in GIS and linking 2-d to 3-d visualisations using low costnet-enabled CAD browsers. We finally conclude with some speculations on thefuture of GIS for urban design across networks whereby a wide range of participantsmight engage in the design process digitally but remotely

An exploratory study investigating factors associated with adherence to chest physiotherapy and exercise in adults with cystic fibrosis

This article is available through Elsevier's Open Access Archives and covered by Elsevier's user license: http://www.elsevier.com/about/open-access/open-access-policies/oa-license-policy/elsevier-user-license.This study explored the relationship between psychological and demographic variables relating to chest physiotherapy (CP) and exercise in adults with cystic fibrosis. The main results were that adherence to both treatments was low and analysis of variance indicated that severity and gender were associated with exercise adherence, importance and burden. These results suggest potential areas for interventions to improve exercise adherence

Fossil Fuel Asset Risk Analysis: Clark University Endowment

The environmental and social risks of climate change are well known and perhaps inevitable. The economic and financial risks are less so. The many financial risks associated with climate change embedded in endowment portfolio fossil fuel holdings are leading many institutional stakeholders to enter into dialogue and take action. Divestment is emerging as an effective strategy for limiting portfolio exposure and tackling climate change itself. Our team’s goals were to assess whether the Clark University endowment portfolio faces any of these risks and evaluate the impacts on asset values. Our findings show that the Clark endowment does face these same climate change related portfolio risks where fossil fuel assets are concerned, that those assets represent approximately $37.2M or 12.11% of the endowment, and that continued investment fails to prevent greater harm or risk to Clark. Our analysis and subsequent recommendations will explain the financial risks Clark fossil fuel assets face as well as options to reduce exposure, ensuring the future of the endowment and the University. The research was done in two phases. Phase One focused on understanding Clark’s institutional mission and values, history of shareholder responsibility, and estimating Clark’s fossil fuel holdings. This was accomplished through interviews with key Clark administrators and staff, literature review, and quantitative analysis of the Clark endowment portfolio for second quarter, 2014. Phase Two focused on evaluating short and long term risks that Clark fossil fuel assets face, research into actions being taken by institutions with similar exposure, and policy options for trustees
