Guoqing Li, Yang Du, Shimao Wang, Sheng Qi, Peili Zhang, Wenzhuo Chen
In this work, LES simulation coupled with a TFC sub-grid combustion model has been performed in a semi-confined pipe (L/D=10, V=10L) in the presence of four hollow-square obstacles (BR=49.8%) with circular hollow cross-section, in order to study the premixed gasoline-air mixture explosions. The comparisons between simulated results and experimental results have been conducted. It was found that the simulated results were in good agreement with experimental data in terms of flame structures, flame locations and overpressure time histories...

Clostridium difficile is the primary cause of healthcare associated diarrhoea globally and produces spores which are resistant to commonly used biocides and are able persist on contaminated surfaces for months. This study examined the effect of sublethal concentrations of the biocide sodium dichloroisocyanurate (NaDCC) on the viability of spores produced by 21 clinical isolates of C. difficile representing a range of PCR ribotypes. Spores exposed to 500 ppm NaDCC for 10 minutes exhibited between a 4 - 6 log10 reduction in viability which was independent of spore PCR ribotype...

BACKGROUND: Gastroesophageal reflux disease (GERD) is the most common gastrointestinal disorder of the esophagus. It is a chronic, progressive disorder that presents most typically with heartburn and regurgitation and atypically with chest pain, dysphagia, chronic cough, globus, or sore throat. The mainstay for diagnosis and characterization of the disorder is esophagoduodenoscopy (EGD), high-resolution esophageal manometry, and symptom-associated ambulatory esophageal pH impedance monitoring...

BACKGROUND: Lumbar epidurals (LEs) provide excellent analgesia. Combined spinal epidural and dural puncture epidural (DPE) are 2 techniques to expedite neuraxial analgesia onset. In DPE, dura is punctured but medication is not administered in the cerebrospinal fluid. Expedited analgesia onset has been demonstrated with DPE, using 0.25% bupivacaine; however, this concentration may impede an unassisted vaginal birth and is not currently used for induction and maintenance of labor analgesia...

The study of ecosystem processes over multiple scales of space and time is often best achieved using comparable data from multiple sites. Yet, long-term ecological observatories have often developed their own data collection protocols. Here, we address this problem by proposing a set of ecological protocols suitable for widespread adoption by the ecological community. Scientists from the European ecological research community prioritized terrestrial ecosystem parameters that could benefit from a more consistent approach to data collection within the resources available at most long-term ecological observatories...

Protection of surface water quality is a key driver in catchment management, particularly for areas undergoing land use change. Changing land use can result in the input of a range of pollutants to surface waters, resulting in water quality impairment, leading to eutrophication and the appearance of algae blooms. This study investigated a mixed land use coastal catchment by undertaking extensive field sampling and data analysis for pollutant source characterisation. The objective was to contribute to a greater understanding of pollutant inputs to surface water resources and for effective catchment management...

White-bellied swiftlets of the Collocalia esculenta complex constitute a radiation of colony-breeding swifts distributed throughout the tropical Indo-Pacific region. Resolution of their taxonomy is challenging due to their morphological uniformity. To analyze the evolutionary history of this complex, we combine new biometric measurements and results from plumage assessment of museum specimens with novel as well as previously published molecular data. Together, this body of information constitutes the largest systematic dataset for white-bellied swiftlets yet compiled, drawn from 809 individuals belonging to 32 taxa for which new molecular, biometric, and/or plumage data are presented...

Purpose In France, all incarcerated prisoners are required to undergo a dental examination (Ministère de la santé et de la protection sociale, 2004 and Ministère de la justice, 2004). However, only one in two prisoners benefits from this oral health check-up. Oral teleconsultation could improve the quality of oral care in prisons. The paper aims to discuss these issues. Design/methodology/approach The focus of this study was therefore to apply oral teleconsultation as an experiment. Using an oral teleconsultation system, a dentist and a nurse were separately asked to give patients a score, according to how urgently their dental issue needed to be treated...

The lower esophageal sphincter (LES) and crural diaphragm (CD) provide the closure mechanism at esophago-gastric junction (EGJ). We used CT imaging in combination with 3D EGJ pressure recordings to determine the functional morphology of the LES and CD and its relationship to the EGJ anatomy. A 3D-HRM catheter recorded the EGJ pressure in 10 healthy subjects. A 0.5 mm diameter metal ball (BB) was taped to the catheter, adjacent to transducer #1. The EGJ pressure was recorded under following conditions; 1) end-expiration (LES pressure) a) before swallow, b) after swallow, and 2) peak inspiration (CD contraction) c) tidal inspiration and d) forced inspiration...

Patients with cardiovascular disease (CVD) are prone to developing erectile dysfunction (ED) due to the common risk factors and pathogenesis underlying ED and CVD. As a result, ED affects nearly 80% of male patients with CVD. The efficacy of phosphodiesterase type 5 inhibitors, vacuum erection devices or intracavernosal injection of vasodilating agents is well established in the treatment of ED; however, their use is limited. Low energy shock-wave therapy (LESWT) is a novel modality that may become a causative treatment for ED...
