OBJECTIVES Sleep patterns have been linked to various health outcomes, but sleep patterns in the British population have not been extensively reported. We aimed to describe the sleep characteristics reported by the European Prospective Investigation of Cancer (EPIC)-Norfolk participants, with a particular emphasis on the comparison of measures of sleep quantity. METHODS From 2006 to 2007, a t...

November 2005, Vol. 95, No. 11 SAMJ Uncertainty as to the cause or causes of sudden and unexpected infant death and difficulty in excluding the possibility of infanticide, even after the performance of a ‘complete’ autopsy, was graphically illustrated in the London courts recently. A mother wrongly convicted of killing her two sons had her conviction quashed, and the eminent paediatrician who h...

The structure changes, microstructure evolution, and mechanical properties during Powder Metallurgy (PM) through High Vacuum Sintering of a Ti-TiH2 matrix reinforced with Titanium Diboride (TiB2) particles were investigated. Composites fabricated at 850, 1100, 1300 °C. strategy for the fabrication process was to use PM route employing titanium hydride (TiH2) reduce consumption Commercially Pure...

A temporarily defunctioning stoma, while effective at reducing symptomatic anastomotic leakage after low anterior resection (LAR) of rectal cancer, and its subsequent closure, is associated with significant morbidity. Here, we devised a new tube ileostomy using a biofragmentable anastomosis ring (TIB) with no need for reversal.This is a retrospective cohort study. From June 2011 to March 2015, ...

In this study, TiB + La2O3/Ti-6Al-4V composites were successfully prepared by in situ reaction using selective laser melting technology. The effect of LaB6 content on the fabrication quality, microstructure evolution and mechanical properties composite samples was investigated. results show that relative density sample gradually decreased from 98.56% to 96.57% as increased 0 wt% 3 wt%. With inc...

Abstract Ni-Ti-Cu alloy can not only prevent scale and biological adhesion, but also has applications in aerospace, automotive engineering, nanotechnology. In this study, Ni 50 Ti 40 Cu 10 45 15 large-size thin-walled parts are prepared on the surface of plates using laser additive manufacturing technology. The optimum operational parameters explored through a two-factor controlled variable met...

Titanium alloys exhibit mechanical and physical properties that fit structural applications demanding light-weight, corrosion resistance and biocompatibility. Ceramic reinforcements can further improve some of these mechanical properties, such as wear resistance, specific stiffness and specific strength. In comparison to continuous reinforced titanium alloys, the particle reinforced alloys (PRT...

Although sensory feedback is important in regulating the timing and magnitude of muscle activity during locomotion few studies have evaluated how it changes after peripheral nerve lesions. To assess this, reflexes evoked by stimulating a nerve before and after denervating other nerves can be quantified to determine changes. The aim of this study was to investigate consequences of denervating an...

Epidemiologic studies have consistently shown that sleeping <7 h and ≥8 h is associated with increased mortality and morbidity. The risks of short sleep may be consistent with results from experimental sleep deprivation studies. However, there has been little study of chronic moderate sleep restriction and little evaluation of older adults who might be more vulnerable to negative effects of sle...
