Green job creation, quality and skills: A review of the evidence on low carbon energy. UKERC Technology and Policy Assessment.

The net employment impacts of a renewable energy or energy efficiency investment account both for jobs that are created, as well as jobs that might be displaced in other parts of the economy as a result of the investment. This report therefore addresses the following research question: How many jobs can be created by policy support for investment in low carbon energy and energy efficiency compared to supporting fossil fuel incumbents? The review identifies a variety of approaches used to estimate the quantity of low carbon energy job creation. It finds that much greater standardisation of methods would be desirable in order to compare how many jobs can be created by policies supporting low carbon energy and energy efficiency, both at a project scale and a wider societal level. Our findings also underline a relative lack of metrics and data measuring quality, skills, and geographic distribution of low carbon job creation, and these should be priority areas for further research

Ebolavirus and Marburgvirus: insight the Filoviridae family

Ebolavirus and Marburgvirus (belonging to the Filoviridae family) emerged four decades ago and cause epidemics of haemorrhagic fever with high case-fatality rates. The genome of filoviruses encodes seven proteins. No significant homology is observed between filovirus proteins and any known macromolecule. Moreover, Marburgvirus and Ebolavirus show significant differences in protein homology. The natural maintenance cycle of filoviruses is unknown, the natural reservoir, the mode of transmission, the epidemic disease generation, and temporal dynamics are unclear. Lastly, Ebolavirus and Marburgvirus are considered as potential biological weapons. Vaccine appears the unique therapeutic frontier. Here, molecular and clinical aspects of filoviral haemorrhagic fevers are summarized

Musculoskeletal radiology teaching at a UK medical school-do we need to improve?

The United Kingdom is currently facing crisis due to a shortage of radiology consultants despite ever‐increasing demand for medical imaging. The specifics of how best to teach radiology has generated increasing interest. This study aims to determine whether musculoskeletal (MSK) radiology teaching at the University of Nottingham (UoN) Medical School is perceived to be satisfactory by medical students, Foundation‐Year doctors, and senior medical professionals in preparing students for the demands working as Foundation‐Year doctors. Questionnaires were distributed to all medical students and Foundation‐Year doctors that graduated from UoN (n = 307). Semi‐structured interviews were conducted with consultants and teaching staff (n = 13). Forty‐nine percent of preclinical medical students, 43% of clinical students and 27% of Foundation‐Year doctors thought MSK radiology teaching was not sufficient in preparing them for the radiology challenges Foundation‐Year doctors’ face. This difference was statistically significant (P < 0.001). The consensus from senior medical professionals was that MSK Radiology teaching is currently adequate and producing competent students. Interestingly, only 5% of students were considering a career in radiology compared to 34% of Foundation‐Year doctors. Overall, there seems to be concern among students regarding MSK radiology teaching and students have a lack of confidence with MSK radiology. Foundation‐Year doctors and senior medical professionals do not share this view. This may be due to medical students’ lack of clarity on what is required of them. Formal documentation of set learning objectives for MSK radiology throughout the curriculum may address this

The changing sensitivity of power systems to meteorological drivers: a case study of Great Britain

The increasing use of intermittent renewable generation (such as wind) is increasing the exposure of national power systems to meteorological variability. This study identifies how the integration of wind power in one particular country (Great Britain, GB) is affecting the overall sensitivity of the power system to weather using three key metrics: total annual energy requirement and peak residual load (from sources other than wind) and wind power curtailment. The present-day level of wind power capacity (approximately 15GW) is shown to have already changed the power system's overall sensitivity to weather in terms of the total annual energy requirement, from a temperature- to a wind-dominated regime (which occurred with 6GW of installed wind power capacity). Peak residual load from sources other than wind also shows a similar shift. The associated changes in the synoptic- and large-scale meteorological drivers associated with each metric are identified and discussed. In a period where power systems are changing rapidly, it is therefore argued that past experience of the weather impacts on the GB power system may not be a good guide for the impact on the present or near-future power system

Silica suspension and coating developments for Advanced LIGO

The proposed upgrade to the LIGO detectors to form the Advanced LIGO detector system is intended to incorporate a low thermal noise monolithic fused silica final stage test mass suspension based on developments of the GEO 600 suspension design. This will include fused silica suspension elements jointed to fused silica test mass substrates, to which dielectric mirror coatings are applied. The silica fibres used for GEO 600 were pulled using a Hydrogen-Oxygen flame system. This successful system has some limitations, however, that needed to be overcome for the more demanding suspensions required for Advanced LIGO. To this end a fibre pulling machine based on a CO2 laser as the heating element is being developed in Glasgow with funding from EGO and PPARC. At the moment a significant limitation for proposed detectors like Advanced LIGO is expected to come from the thermal noise of the mirror coatings. An investigation on mechanical losses of silica/tantala coatings was carried out by several labs involved with Advanced LIGO R&D. Doping the tantala coating layer with titania was found to reduce the coating mechanical dissipation. A review of the results is given here

Search for Gravitational-wave Inspiral Signals Associated with Short Gamma-ray Bursts During LIGO's Fifth and Virgo's First Science Run

Progenitor scenarios for short gamma-ray bursts (short GRBs) include coalescenses of two neutron stars or a neutron star and black hole, which would necessarily be accompanied by the emission of strong gravitational waves. We present a search for these known gravitational-wave signatures in temporal and directional coincidence with 22 GRBs that had sufficient gravitational-wave data available in multiple instruments during LIGO's fifth science run, S5, and Virgo's first science run, VSR1. We find no statistically significant gravitational-wave candidates within a [ – 5, + 1) s window around the trigger time of any GRB. Using the Wilcoxon-Mann-Whitney U-test, we find no evidence for an excess of weak gravitational-wave signals in our sample of GRBs. We exclude neutron star-black hole progenitors to a median 90% confidence exclusion distance of 6.7 Mpc
