Simple drag prediction strategies for an Autonomous Underwater Vehicle’s hull shape
No full textThe range of an AUV is dictated by its finite energy source and minimising the energy consumption is required to maximise its endurance. One option to extend the endurance is by obtaining the optimum hydrodynamic hull shape with balancing the trade-off between computational cost and fluid dynamic fidelity. An AUV hull form has been optimised to obtain low resistance hull. Hydrodynamic optimisation of hull form has been carried out by employing five parametric geometry models with a streamlined constraint. Three Genetic Algorithm optimisation procedures are applied by three simple drag predictions which are based on the potential flow method. The results highlight the effectiveness of considering the proposed hull shape optimisation procedure for the early stage of AUV hull desig
Interatrial shunt devices for heart failure with normal ejection fraction: a technology update
No full textJoseph J Cuthbert, Pierpaolo Pellicori, Andrew L Clark Department of Cardiology, Hull York Medical School, Hull and East Yorkshire Medical Research and Teaching Centre, Castle Hill Hospital, Cottingham, Kingston upon Hull, UK Abstract: Heart failure with normal ejection fraction (HeFNEF) accounts for ~50% of heart failure admissions. Its pathophysiology and diagnostic criteria are yet to be defined clearly which may hinder the search for effective treatments. The clinical hallmark of HeFNEF is exertional breathlessness, often due to an abnormal increase in left atrial pressure during exercise. Creation of an interatrial communication to offload the left atrium is a possible therapeutic approach. There are two percutaneously delivered devices currently under investigation which are discussed in this review. Keywords: IASD, V-Wave, device therapy, HeFNEF, review, preserved EF, HeFPEF, HFpE
The lichen flora of Hull, with particular reference to zonal distribution and environmental monitoring
No full textYesThe role of lichens as environmental monitors is widely recognised. Not only are they valuable as indicators of habitat stability and enyironmental continuity, but they are also effectiye in monitoring environmental quality. more particularly air and soil (and more recently water) pollution. In the past. the main role of lichens in this context has been to
monitor sulphur dioxide air pollution. especially stable and rising levels (Seaward 1993).
Howeyer, it has also been shown that lichens arc effective monitors of falling levels of
gaseous sulphur dioxide and indeed of other pollutants. some of which are manifesting
themselves as a consequence of the reduction in the former; of particular interest in this
respect is the use of lichens to detect and determine the extent of qualitative changes in air pollution such as the impact of acid rain and hypertrophication (Seaward 1997: Seaward & Coppins 2(04)
Recommendations for changes in UK National Recovery Guidance (NRG) and associated guidance from the perspective of Lancaster University's Hull Flood Studies
No full textThis report was commissioned by the Civil Contingencies Secretariat (CCS) following the publication of Lancaster University‟s Hull Flood Project and Hull Children‟s Flood Project. Its principal purpose is to identify how findings made as a result of the two research projects could be integrated into the Cabinet Office‟s National Recovery Guidance (NRG), as a means to improve affected communities‟ ability to recover from emergency events.
The report, in effect, details a desktop analysis of UK Civil Protection (CP) guidance, from a bottom-up perspective (i.e. using as its critical lens, the lived experiences of members of the public who were tested by the Hull flooding of 2007 and its aftermath)
High sensitivity C-reactive protein in chronic heart failure: patient characteristics, phenotypes, and mode of death
No full textAims:
Plasma concentrations of high-sensitivity C-reactive protein (hsCRP) are often raised in chronic heart failure (CHF) and might indicate inflammatory processes that could be a therapeutic target. We aimed to study the associations between hsCRP, mode and cause of death in patients with CHF.
Methods and results:
We enrolled 4423 patients referred to a heart failure clinic serving a local population. CHF was defined as relevant symptoms or signs with either a reduced left ventricular ejection fraction <40% or raised plasma concentrations of amino-terminal pro-B type natriuretic peptide (NT-proBNP >125 pg/mL). The median [interquartile range (IQR)] plasma hsCRP for patients diagnosed with CHF (n = 3756) was 3.9 (1.6–8.5) mg/L and 2.7 (1.3–5.1) mg/L for those who were not (n = 667; P < 0.001). Patients with hsCRP ≥10 mg/L (N = 809; 22%) were older and more congested than those with hsCRP <2 mg/L (N = 1117, 30%). During a median follow-up of 53 (IQR 28–93) months, 1784 (48%) patients with CHF died. Higher plasma hsCRP was associated with greater mortality, independent of age, symptom severity, creatinine, and NT-proBNP. Comparing a hsCRP ≥10 mg/L to <2 mg/L, the hazard ratio for all-cause mortality was 2.49 (95% confidence interval 2.19–2.84; P < 0.001), for cardiovascular (CV) mortality was 2.26 (1.91–2.68; P < 0.001), and for non-CV mortality was 2.96 (2.40–3.65; P < 0.001).
Conclusion:
In patients with CHF, a raised plasma hsCRP is associated with more congestion and a worse prognosis. The proportion of deaths that are non-CV also increases with higher hsCRP
Contributions to the History of Psychology: LXXXVI. Hull and His Critics: The Reception of Clark L. Hull's Behavior Theory, 1943–1960
No full text In the twelve-year period following the publication of Principles of Behavior in 1943, Clark L. Hull was regarded as a leading proponent of systematic behavior theory. By the end of the 1950s, his visibility in the psychological literature had greatly diminished and his contributions to psychological theory were judged by many to have been misguided. Drawing from reviews and assessments of Hull's theorizing which appeared in the period 1943–1960, this paper treats Hull's impact and subsequent decline as inevitable outcomes of the programmatic nature of Hull's behavior theory. </jats:p

Presentation of acute heart failure and its consequences
No full textBackground: Acute heart failure (AHF) is a heterogeneous in aetiology, pathophysiology and presentation and very difficult to classify. Despite this diversity, clinical trials in AHF deal with this syndrome as a single entity, which may be one reason for repeated failures. It is generally believed that patients with AHF present with severe breathlessness at rest but epidemiological data suggest otherwise.Methods: Different data sets were used to assess the presentation of AHF and its consequences. I conducted a detailed case note review to determine what proportions of patients were Short Of Breath At Rest (SOBAR) and Comfortable At Rest but Breathless On Slight Exertion (CARBOSE). Euro Heart Failure Survey 1 (EHFS1) screened consecutive deaths and discharges during 2000-2001 in 24 countries, to ascertain patients with known or suspected Heart Failure (HF). Information on presenting symptoms and signs were gathered. Mortality was assessed during hospital admission and then 3 months after discharge.Results: Of 697 patients, those with SOBAR (45%) had higher median heart rate blood pressure and respiratory rate and these changed quickly in first 24 hours after presentation as compare to CARBOSE (55%) but had better long term prognosis. Of all 10,701 patients admitted with suspected HF in EHFS1, Heart failure was considered to be the primary reason for admission in 4,234 (40%), secondary reason for admission if complicated or prolonged stay in further 1,772 (17%), and in 4,695 (43%) it was uncertain that HF is actively contributing in index admission. Mortality was highest in the secondary heart failure group and lowest in the uncertain group. Heart failure with cardiac arrest/ventricle arrhythmia had worst mortality followed by HF with ACS but considerable number of patients died in uncertain group.Conclusion: AHF is complex, with diverse presentations that are associated with very different subsequent prognosis. Attempts to investigate the effect of agents in all patients with a diagnosis of AHF may be futile. A more coherent approach of focused and tighter patient selection for drug therapy targeted by clinical presentation is more likely to succeed
