Over the past two years students taking two biology modules at the University of Derby have been assessed using computer assessments with TRIADs (Tripartite Interactive Assessment Delivery System) in both their formal end of module examinations and for scored formative assessments. We were keen to establish the student views of the use of computer assessment and thus over this period in additio...
Polyploidy, hybridization and variation in mating systems are central issues for a deeper understanding of animal evolution. The Iberian species Squalius alburnoides represents an example combining all three phenomena. Previous studies showed that S. alburnoides populations are mainly composed of triploid and diploid hybrid forms (mainly females), and that the tetraploid forms are rare or absen...
A Japanese woman developed gait disturbances at 25 years of age, and subsequently underwent gradual changes in her personality. By the age of 42, she showed clear signs of dementia and cerebellar ataxia, and displayed behavioral abnormalities, choreic movements and hyperreflexia. The findings of MRI not only showed cerebellar and cerebral atrophy, but also revealed putaminal rim hyperintensity ...
In Bell v. Cheswick Generating Station, the U.S. Court of Appeals for the Third Circuit reversed a decision by the U.S. District Court for the Western District of Pennsylvania, holding that state common law tort actions were not preempted by the federal Clean Air Act (“CAA”). The Third Circuit found that the savings clause of the CAA was nearly identical to that of the Clean Water Act (“CWA”), ...
Mapping and diagnosis of infections by the three major schistosome species (Schistosoma haematobium, S. mansoni and S. japonicum) has been done with assays that are known to be specific but increasingly insensitive as prevalence declines or in areas with already low prevalence of infection. This becomes a true challenge to achieving the goal of elimination of schistosomiasis because the multipl...
Implementation issues for digital reduced-order observer-based controllers with Finite Word Length (FWL) considerations is studied. A tractable FWL stability related mesure is derived, and the optimal FWL realization problem for digital reduced-order obverserbased controller is to find those realizations that maximize this related measure. This optimization problem is formulated as an unconstra...
OBJECTIVE We evaluated recurrent intracerebral hemorrhage (ICH) risk in ICH survivors, stratified by the presence, distribution, and number of cerebral microbleeds (CMBs) on MRI (i.e., the presumed causal underlying small vessel disease and its severity). METHODS This was a meta-analysis of prospective cohorts following ICH, with blood-sensitive brain MRI soon after ICH. We estimated annualiz...
BACKGROUND Accurate risk prediction of coronary artery aneurysms (CAAs) in North American children with Kawasaki disease remains a clinical challenge. We sought to determine the predictive utility of baseline coronary dimensions adjusted for body surface area (z scores) for future CAAs in Kawasaki disease and explored the extent to which addition of established Japanese risk scores to baseline ...
INTRODUCTION Transient global amnesia (TGA) is an episode of severe anterograde amnesia of sudden onset, characteristically lasting 4 to 6 h. Patients become disorientated in time and place, but not in person. Automated motor tasks are preserved; however, the retention of new information is impaired, with clear implications to a pilot's fitness to fly. This study examines the United Kingdom Civ...
This study investigated the efficacy of different sanitizers, including acidic electrolyzed water (AEW), peroxyacetic acid (POAA), and chlorine, on the inactivation of Escherichia coli O157:H7 on fresh-cut apples. The effects of the sanitizers and sequential treatments of AEW or POAA followed by calcium ascorbate (CaA) on browning inhibition and organoleptic qualities of fresh-cut apples stored...
