Core noise measurements on a YF-102 turbofan engine
Core noise from a YF-102 high bypass ratio turbofan engine was investigated through the use of simultaneous measurements of internal fluctuating pressures and far field noise. Acoustic waveguide probes, located in the engine at the compressor exit, in the combustor, at the turbine exit, and in the core nozzle, were employed to measure internal fluctuating pressures. Spectra showed that the internal signals were free of tones, except at high frequency where machinery noise was present. Data obtained over a wide range of engine conditions suggest that below 60% of maximum fan speed the low frequency core noise contributes significantly to the far field noise
Talking about food choices of former homeless young people: making sense of conflicting discourses of blame through social worlds theory.
After a pilot study at a charitable youth organisation in the North East of Scotland found no considerable improvements in the food choices of former homeless young people accommodated by the organisation (Perry, 2013), the Foodways and Futures project (2013-2016) set out to explore why. Both members of staff at the same organisation as well as young people were invited to voice their views and opinions on the factors influencing young people’s food choices. Whilst everyone’s contribution was considered equally informative for our findings, I was attentive to where the information originated from. In this, I found that three conflicting discourses of blame pervade the participants’ expressions of the rationales underlying young people’s food choices. Trying to make sense of these, I employ Strauss’ Social Worlds Theory (1978). I find that the different discourses of blame make sense in the context of the complex organisational structures. In objecting to a tendency in the literature to assign standardised discourse of blame primarily to youth workers’ practice, these discourses showcase mutual understanding instead
Relationship between emergency presentation, systemic inflammatory response, and cancer-specific survival in patients undergoing potentially curative surgery for colon cancer
Background
Emergency presentation is recognized to be associated with poorer cancer-specific survival following curative resection for colorectal cancer. The present study examined the hypothesis that an enhanced systemic inflammatory response, prior to surgery, might explain the impact of emergency presentation on survival.
Methods
In all, 188 patients undergoing potentially curative resection for colorectal cancer were studied. Of these, 55 (29%) presented as emergencies. The systemic inflammatory response was assessed using the Glasgow Prognostic Score (mGPS), which is the combination of an elevated C-reactive protein (>10 mg/L) and hypoalbuminemia (<35 g/L).
Results
In the emergency group, tumor stage was greater (P < 0.01), more patients received adjuvant therapy (P < 0.01) more patients had an elevated mGPS (P < 0.01), and more patients died of their disease (P < 0.05). The minimum follow-up was 12 months; the median follow-up of the survivors was 48 months. Emergency presentation was associated with poorer 3-year cancer-specific survival in those patients aged 65 to 74 years (P < 0.01), in both males and females (P < 0.05), in the deprived (P < 0.01), in patients with tumor-node-metastasis (TNM) stage II disease (P < 0.01), in those who received no adjuvant therapy (P < 0.01), and in the mGPS 0 and 1 groups (P < 0.05) groups. On multivariate survival analysis of patients undergoing potentially curative surgery for TNM stage II colon cancer, emergency presentation (P < 0.05) and mGPS (P < 0.05) were independently associated with cancer-specific survival.
Conclusions
These results suggest that emergency presentation and the presence of systemic inflammatory response prior to surgery are linked and account for poorer cancer-specific survival in patients undergoing potentially curative surgery for colon cancer. Both emergency presentation and an elevated mGPS should be taken into account when assessing the likely outcome of these patients
Preoperative systemic inflammation predicts postoperative infectious complications in patients undergoing curative resection for colorectal cancer
The presence of systemic inflammation before surgery, as evidenced by the glasgow prognostic score (mGPS), predicts poor long-term survival in colorectal cancer. The aim was to examine the relationship between the preoperative mGPS and the development of postoperative complications in patients undergoing potentially curative resection for colorectal cancer. Patients (n=455) who underwent potentially curative resections between 2003 and 2007 were assessed consecutively, and details were recorded in a database. The majority of patients presented for elective surgery (85%) were over the age of 65 years (70%), were male (58%), were deprived (53%), and had TNM stage I/II disease (61%), had preoperative haemoglobin (56%), white cell count (87%) and mGPS 0 (58%) in the normal range. After surgery, 86 (19%) patients developed a postoperative complication; 70 (81%) of which were infectious complications. On multivariate analysis, peritoneal soiling (P<0.01), elevated preoperative white cell count (P<0.05) and mGPS (P<0.01) were independently associated with increased risk of developing a postoperative infection. In elective patients, only the mGPS (OR=1.75, 95% CI=1.17-2.63, P=0.007) was significantly associated with increased risk of developing a postoperative infection. Preoperative elevated mGPS predicts increased postoperative infectious complications in patients undergoing potentially curative resection for colorectal cancer

GAP WORK project report: training for youth practitioners on tackling gender-related violence
This project sought to challenge gender-related violence against (and by) children and young people by developing training for practitioners who have everyday contact with general populations of children and young people (‘youth practitioners’). Through improved knowledge and understanding practitioners can better identify and challenge sexist, sexualising, homophobic or controlling language and behaviour, and know when and how to refer children and young people to the most appropriate support services. This summary outlines the Project and our initial findings about the success of the four training programmes developed and piloted.Co-funded by the DAPHNE III programme of the EU
Length-Weight Relationships, Fat Content and Parasitic Infestation of Irish Mackerel
Landings of mackerel by Irish vessels have increased dramatically in recent years. The total catch in 1982 amounted to 110,000 tonnes which was valued at about 8.5 million pounds, compared with only 8,500 tonnes, values at 0.36 million pounds in 1974. The major cause of the increase has been the introduction of six large trawlers into the fleet around 1980 as a result of which the total catch jumped from 24,000 tonnes in 1979 to 80,000 tonnes in 1980. The main landings into Irish ports are made at Killybegs and Rathmullen, while smaller landings are made into Castletownbere and Galway. Since 1983 considerable quantities have also been landed into western Scottish ports. Most of the catches are taken off the west and northwest coast but again since 1983 the Irish fleet has successfully fished over a wide area extending from west of the Shetland Islands down to Cornwall
