Introduction: PROPELLER-MRI is a multi-shot fast spin-echo (FSE) data acquisition technique that is gaining popularity due to its reduced sensitivity to motion and B0 inhomogeneities. However, k-space sampling in PROPELLER is performed on a set of parallel lines forming a blade, which is rotated to cover k-space. This sampling pattern oversamples the central region of k-space, and PROPELLER acq...

OBJECTIVE To compare intubation times and ease of use for a range of infant laryngoscope blades in the hands of accident and emergency (A&E) personnel. METHODS Seven different blades were compared in terms of intubation times and ease of use scores in the hands of 30 A&E senior house officers (SHOs) and nurses using a standard infant manikin. RESULTS There was a significant difference in in...

The aim of this study was to re-assess whether the use of a 'one-knife technique' can be considered as safe as the alternative practice of using separate skin and inside knives for elective orthopaedic surgery. A total of 609 knife blades from 203 elective orthopaedic operations, with equal numbers of skin, inside and control blades, were cultured using direct and enrichment media. We found 31 ...

Neotyphodium uncinatum and Neotyphodium siegelii are fungal symbionts (endophytes) of meadow fescue (MF; Lolium pratense), which they protect from insects by producing loline alkaloids. High levels of lolines are produced following insect damage or mock herbivory (clipping). Although loline alkaloid levels were greatly elevated in regrowth after clipping, loline-alkaloid biosynthesis (LOL) gene...

in this study, attempts were made to recovery the used turbine blades made up of inconel738 by electro slag remelting (esr) method. using an appropriate slag and addition of metallic aluminum, the original composition was maintained and the amount of oxygen, hydrogen and nitrogen remained in the acceptable level. in order to explore the effect of remelting with esr on the microstructure, tensil...

Existing corn harvester cutting blades have problems associated with large cutting resistance, high energy consumption, and poor cut quality. Using bionics principles, a bionic blade was designed by extracting the cutting tooth profile curve of the B. horsfieldi palate. Using a double-blade cutting device testing system, a single stalk cutting performance contrast test for corn stalks obtained ...

BACKGROUND AND AIMS Hepatitis B virus (HBV) infection ranks among the most devastating health problems in the world.The most probable transmission routes of HBV are blood contact, sexual, and horizontal transfer. Other sources of HBV transmission are razor sharing, beauty treatments, tattooing, piercing, and manicures and other chiropody treatments.Many infections have been reported in South-Ea...
