A process yields large quantities of pure ribosome subunits

Development of process for in-vitro protein synthesis from living cells followed by dissociation of ribosomes into subunits is discussed. Process depends on dialysis or use of chelating agents. Operation of process and advantages over previous methods are outlined

21st Century Managers and Intuition: Evaluating the learning achieved from an Example of Pedagogic Change for Business Undergraduates

A key requirement for effective research on pedagogy and course redesign is a credible measure (or measures) of student learning on completion of individual modules or even specific teaching initiatives. This has proved difficult to achieve for business courses for some subjects - in particular for the teaching of soft skills such as team working. Traditional methods such as examinations are inappropriate. This paper reports on a novel approach to the evaluation of an exercise, designed to develop business students’ skill of managerial intuition. Changing business conditions are placing a greater value on managers’ ability to deal with open-ended complex (wicked) problems. One academic stream of work has identified that managerial intuition is the key to handling such problems effectively. This, like all skills, can best be acquired through practice. An exercise designed to give small teams of students experience of such a problem was designed for a module delivered during the 1st year of a business degree at Business SchoolX. In parallel students were required to carry out both team and individual reflections that focused on the learning achieved on this exercise. Since the reflective practice was required and marked this ensured that we obtained a comprehensive response from almost all students on the course. Reflective practice can be anonymised and draws on an individual’s most deeply held thinking. This year (2015/16) is the first attempt at carrying out an evaluation exercise of this type. The paper reports on the preliminary results from the Autumn Term module

Tracking productivity in real time

Because volatile short-term movements in productivity growth obscure the underlying trend, shifts in this trend may go unrecognized for years - a lag that can lead to policy mistakes and hence economic instability. This study develops a model for tracking productivity that brings in additional variables to help reveal the trend. The model's success is evident in its ability to detect changes in trend productivity within a year or two of their occurrence. Currently, the model indicates that the underlying trend remains strong despite recent weak productivity data.Industrial productivity - Measurement ; Economic policy ; Econometric models

CF6 Jet Engine Performance Improvement: High Pressure Turbine Active Clearance Control

An active clearance control system was developed which reduces fuel consumption and performance degradation. This system utilizes compressor discharge air during takeoff and fan discharge air during cruise to impinge on the shroud structure to improve the thermal response. The system was evaluated in component and engine tests. The test results demonstrated a performance improvement of 0.7 percent in cruise SFC

The Bright Ages Survey. II. Evolution of Luminosity, Dust Extinction, and Star Formation from z = 0.5 to z = 2.5

The Bright Ages Survey is a K-band-selected redshift survey over six separate fields with UBVRIzJHK imaging covering a total of 75.6 arcmin(2) and reaching K = 20-20.5. Two fields have deep HST imaging, while all are centered on possible overdensities in the z similar to 2 range. Here we report photometric redshifts and spectroscopy for this sample, which has been described in Paper I. We find 18 galaxies with spectroscopic redshifts of z > 1:5. The derived rest-frame R-band luminosity functions show strong evolution out to z = 2. The luminosity function at z = 2 shows more bright galaxies than at any other epoch, even the extrapolated z = 3 luminosity function from Shapley et al. However, the R-band integrated luminosity density remains roughly constant from to z = 0:5 to z = 2. Evolved galaxies (E, S0, Sa) show a decreasing contribution to the total R-band luminosity density with redshift. The dust extinction in our K-selected sample is moderately larger [median z = 2 E(B - V) 0:30] than that found in Lyman break galaxies, although not enough to make a significant impact on the total light or star formation found at high redshift. We measure the extinction-corrected star formation rate density at z 2, finding ρ_(SFR)(z = 1.5-2.5)= 0.093 M_⊙ yr^(-1) Mpc^(-3), consistent with a relatively flat instantaneous star formation rate from z = 1-4
