BACKGROUND A doctor's competence and professionalism is often judged on the basis of attire. Our Lady of Lourdes (OLOL) is a leading Irish hospital in the implementation of Bare Below the Elbows (BBTE) policy, however surgical attire is not standardised and there is great variability in attire worn on wards. We aimed to evaluate patients attitude towards surgeons attire in OLOL. METHODS A pro...

[1] Dust grains on the lunar surface are exposed to UV radiation and solar wind plasma and can collect electrical charges, leading to their possible lift-off and transport in the presence of near-surface electric fields. Motivated by the long-standing open questions about the physics of electrostatic lunar dust transport, we investigated the dynamics of dust grains on a conducting surface in a ...

Underwater bubbles can inhibit sound transmission through water due to density mismatch and concomitant reflection and absorption of sound waves. For the present study, a perforated rubber hose was used to produce a bubble curtain, or screen, around pile-driving activity in 6-8-m depth waters of western Hong Kong. The percussive hammer blow sounds of the pile driver were measured on 2 days at d...

Autonomous manipulation in unstructured environments presents roboticists with three fundamental challenges: object segmentation, action selection, and motion generation. These challenges become more pronounced when unknown manmade or natural objects are cluttered together in a pile. We present an end-to-end approach to the problem of manipulating unknown objects in a pile, with the objective o...

stabilization of earth slopes with various proposed methods is one of the important concerns of geotechnical engineering. in this practice, despite numerous developments, design conservativeness and high costs of stabilization are the issues yet to be addressed. this paper not only deals with pile location optimization but also studies the effects of the pile length by using line segments slip ...

The belled anchor pile has proficient application in the field of geotechnical engineering as because its enlarged base can bear more compressive loads and large volume of breakout soil within slip surface move upward under tension. The bell anchor pile can be used in case of on-land and off-shore structures where there is a threat to overturning of structures due to external tension loads. The...

Ground green waste is used as mulch in ornamental landscapes and for tree crops such as avocados. Survival of Armillaria mellea, Phytophthora cinnamomi, Sclerotinia sclerotiorum, and Tylenchulus semipenetrans was assessed for 8 weeks within unturned piles of either recently ground or partially composted green waste. S. sclerotiorum survived at the pile surface and at 10, 30, and 100 cm within t...

The sensitivity of the seismic response parameters to the uncertain modeling variables of pile-founded fixed steel jacket platforms are investigated using the Tornado diagram and the first-order second-moment techniques. The effects of both aleatory and epistemic uncertainty on seismic response parameters have been investigated for an existing offshore platform. The sources of uncertainty consi...

Cone penetration test is one of the most common in-situ tests for pile analysis given that by its analogy as a model pile, the measured cone resistance and sleeve friction can be employed for estimation of pile unit toe and shaft resistances, respectively. In this paper, group method of data handling (GMDH)-type neural networks optimized using Genetic algorithms (GAs) are used for modelling the...

We made a 'pile-up' microreactor in which ten levels of microchannel circuits were integrated to form a single glass entity. Solutions were distributed to each layer via cylindrical holes with a diameter much larger than that of the microchannel. Fabrication of the pile-up reactor was completed using only conventional photolithography, wet etching and thermal bonding techniques, and no special ...
