Genomic organization of the mouse T-cell receptor β-chain gene family

We have combined three different methods, deletion mapping of T-cell lines, field-inversion gel electrophoresis, and the restriction mapping of a cosmid clone, to construct a physical map of the murine T-cell receptor β-chain gene family. We have mapped 19 variable (Vβ) gene segments and the two clusters of diversity (Dβ) and joining (Jβ) gene segments and constant (Cβ) genes. These members of the β-chain gene family span ~450 kilobases of DNA, excluding one potential gap in the DNA fragment alignments

Managing demand in the North East.

Local authorities and Regional Transport Partnerships may need to be seen to be reacting to the Scottish Government’s inclusion of Workplace Parking Charges in the recent Transport Scotland Bill, with provisions soon to be enshrined in legislation. The Nestrans Board has expressed a desire to explore this issue in the context of wider demand management measures. As organisations, there is a need to have evidence to express meaningful views when faced with questions regarding demand management. Furthermore, the wider policy context operating in the North East of Scotland must also be reflected upon and due regard given to the existing local, regional and national transport policy objectives and how the forthcoming regional transport strategy will set the future agenda for how businesses and citizens travel in and around the region in a sustainable way

The state of global surveying education: final report.

This research was commissioned through a joint proposal issued by CHOBE and the RICS to provide an overview report on surveying education across the globe. CHOBE note that since their initial 'State of the Nation' analysis of Built Environment in 2008, and subsequent iterations in 2010 and 2015, the national and international landscapes around higher education and built environment provision have changed significantly. In particular, the global reach of the RICS has expanded, and developments around in-country provision and trans-national education (TNE) have gained scale and maturity. It was considered timely to produce a globally-relevant review of the state of surveying education, extending to wider built environment domains that reflect the current position. Working in collaboration with international partners from institutions in Sri Lanka, Canada, Australia and Nigeria, the purpose of this project is to build on previous research regarding education and pedagogy within the field of surveying. The research aims to define the overarching themes that have emerged, both globally and regionally, with regard to the scope and context of teaching surveying within higher education institutions. As the global education market diversifies with an apparent move towards embracing work-based and postgraduate options as a central stream for entrants to the industry, the project aims to explore, analyse and represent the current state and likely future directions for surveying education in selected global regions. This report provides a current snapshot of global surveying education, which can be used to direct future work towards focussed areas of study, engagement and application

On frontal and ventilated models of the main thermocline

A new similarity approach is applied to the thermocline equations in order to examine contrasting frontal and ventilated models of the main thermocline. The method of solution involves reducing the number of independent variables of the controlling partial differential equation, leading to a particular form for the solutions which satisfy appropriate boundary conditions. A frontal model of the thermocline is obtained following the study of Salmon and Hollerbach (1991). When the vertical diffusivity becomes vanishingly small, an interior front in the subtropical gyre appears at the depth where the vertical velocity changes sign. The front separates downwelling warm water in the subtropical gyre from the underlying upwelling of cold, deep water. These solutions appear to be robust to changes in the vertical diffusivity profile, as long as there is a small, nonzero value in the interior. However, when there is uniform diffusivity, there is no implied surface heat flux and surface isotherms are coincident with streamlines. As the diffusivity increases toward the surface, the surface heat input increases in magnitude and the temperature field becomes more plausible. A ventilated model of the thermocline is formed using the similarity approach with a diffusive surface boundary-layer overlying an adiabatic interior. In this case, the temperature and velocity fields are solved for in the limit of uniform potential vorticity. There is now a more plausible cross-isothermal flow in the surface layer with a polewards decrease in temperature, and the implied surface heat input increases equatorwards. Fluid is subducted from the surface boundary layer into the adiabatic interior and forms a continuous thermocline. In conclusion, the contrasting frontal and ventilated solutions arise from modeling different aspects of the circulation, rather than depending on the type of model employed. The ventilated solutions form a thermocline by advecting the surface temperature field into the interior of a subtropical gyre, whereas the frontal solutions create a thermocline from the interaction of the wind-driven gyre and the underlying thermohaline circulation. These thermocline solutions might occur separately or together in the real ocean, although both solutions might be modified by higher-order processes or more complicated forcing

This is the program for the joint senior recital of Scott Richard Thornhill and soprano Cynthia Faye Hood. Mr. Thornhill was accompanied by Suzanne Norris on the piano, and Ms. Hood was accompanied on the piano by Pamela Dennis. This recital took place on April 4, 2004, in the McBeth Recital Hall in the Mabee Fine Arts Center

Workpiece surface integrity when milling Udimet 720 superalloy

AbstractThe paper details a comprehensive investigation into the surface integrity of Udimet 720 following end milling under different environment conditions (dry, flood, higher pressure and MQL) and cutting speed (25 and 50m/min). Surface roughness (Ra) was < 0.25μm regardless of tool condition with no white layers detected on any of the samples analysed. Residual stress measurements indicated surface compressive stress of 120MPa on workpieces milled using new cutters under MQL environment. In contrast, worn tools produced surface tensile stresses of ∼80MPa, with subsurface compressive residual stress of up to ∼400MPa at a depth of 80μm
