Emergency planing

Jerry Godfrey Makama, Istifanus Anekoson Joshua, Elizabeth Jerry Makama
BACKGROUND: There has been an increase in the incidence of disasters in many parts of the world. Similarly, Nigeria has witnessed a recent increase of man-made disaster events such as plane crash, fire incidents, flood, and building collapse, including bomb blast orchestrated by terrorists that often create emergency situations. Therefore, the aim of the study was to evaluate family emergency plan and preparedness among medical practitioners in Zaria. METHODS: This was a cross-sectional descriptive study (May-July, 2013) of medical practitioners in Zaria, Nigeria...

The aim of this study was to determine the factors that may predict failure of closed reduction and casting of diaphyseal forearm fractures in children. Demographic and radiographic data of children with closed reduction and casting of these fractures in the emergency department were evaluated. Of 174 patients with adequate follow-up to union, 19 (11%) required a repeat procedure. Risk factors for repeat reduction included translation of 50% or more in any plane, age more than 9 years, complete fracture of the radius, and follow-up angulation of the radius more than 15° on lateral radiographs or of the ulna more than 10° on anteroposterior radiographs...

Spin-wave devices (SWD), which use collective excitations of electronic spins as a carrier of information, are rapidly emerging as potential candidates for post-semiconductor non-charge-based technology. Isotropic in-plane propagating coherent spin waves (magnons), which require magnetization to be out of plane, is desirable in an SWD. However, because of lack of availability of low-damping perpendicular magnetic material, a usually well-known in-plane ferrimagnet yttrium iron garnet (YIG) is used with a large out-of-plane bias magnetic field, which tends to hinder the benefits of isotropic spin waves...

Ab-initio calculations are performed to examine the electronic structures and magnetic properties of spin-polarized Ga1-xMnxP (x = 0.03, 0.25, 0.5, and 0.75) ternary alloys. In order to perceive viable half-metallic (HM) states and unprecedented diluted magnetic semiconductors (DMSs) such as spintronic materials, the full potential linearized augmented plane wave method is utilized within the generalized gradient approximation (GGA). In order to tackle the correlation effects on 3d states of Mn atoms, we also employ the Hubbard U (GGA + U) technique to compute the magnetic properties of an Mn-doped GaP compound...

Painful rib fractures may be a factor in trauma patients remaining intubated and being given postoperative mechanical ventilation after emergency surgery. Regional techniques could provide sufficient analgesia in these patients to enable weaning and extubation and thus prevent or minimize complications related to prolonged ventilatory support. We describe a trauma patient with multiple rib fractures requiring an emergency splenectomy for whom an ultrasound-guided serratus plane block provided good quality pain relief for his rib fractures and enabled fast-track extubation in the operating room...

BACKGROUND: One of the most frequently performed emergency surgical procedures in children is an appendectomy. The aim of this study was to determine the benefits of supplementing standard, general anaesthesia with the ultrasound-guided right TAP block. METHODS: We analyzed the medical records of 90 children of both sexes, aged 4-16 years with a body mass of 16-78 kg who underwent general anaesthesia for open appendectomy. Sixty-two individuals were anaesthetized using the standard method, while 28 patients had an additional right-sided TAP block under ultrasound guidance...

Bioprinting is an emerging technique for the fabrication of living tissues that allows cells to be arranged in predetermined three-dimensional (3D) architectures. However, to date, there are limited examples of bioprinted constructs containing multiple cell types patterned at high-resolution. Here we present a low-cost process that employs 3D printing of aqueous droplets containing mammalian cells to produce robust, patterned constructs in oil, which were reproducibly transferred to culture medium. Human embryonic kidney (HEK) cells and ovine mesenchymal stem cells (oMSCs) were printed at tissue-relevant densities (10(7) cells mL(-1)) and a high droplet resolution of 1 nL...

Linear dichroism - the polarization dependent absorption of electromagnetic waves- is routinely exploited in applications as diverse as structure determination of DNA or polarization filters in optical technologies. Here filamentary absorbers with a large length-to-width ratio are a prerequisite. For magnetization dynamics in the few GHz frequency regime strictly linear dichroism was not observed for more than eight decades. Here, we show that the bulk chiral magnet Cu2OSeO3 exhibits linearly polarized magnetization dynamics at an unexpectedly small frequency of about 2 GHz at zero magnetic field...

We study the emergence of chimera states in a multilayer neuronal network, where one layer is composed of coupled and the other layer of uncoupled neurons. Through the multilayer structure, the layer with coupled neurons acts as the medium by means of which neurons in the uncoupled layer share information in spite of the absence of physical connections among them. Neurons in the coupled layer are connected with electrical synapses, while across the two layers, neurons are connected through chemical synapses...

Identifying effective methods to enhance the properties of catalysts is urgent to broaden the scanty technologies, so far. Herein, we synthesized four Co3O4 crystals with different crystal planes and explored the crystal planes' effects on electrochemical water splitting through theoretical and experimental studies for the first time. The results illustrate that the correlation of catalytic activity is established as {111} > {112} > {110} > {001}. Co3O4 crystals exposed with {111} facets show the highest OER (oxygen evolution reaction) and HER (hydrogen evolution reaction) activities...

Bone features a hierarchical architecture combining antagonistic properties like toughness and strength. In order to better understand the mechanisms leading to this advantageous combination, its postyield and failure behavior was analyzed on the length scale of a single lamella. Micropillars were compressed to large strains under hydrated conditions to measure their anisotropic yield and post-yield behavior. An increase in strength compared to the macroscale by a factor of 1.55 and a strong influence of hydration with a decrease by 60% in yield stress compared to vacuum conditions were observed...

OBJECTIVE: Ultrasound-guided (USG) cannulation of the brachiocephalic vein (BCV) has been shown to be technically easy. We hypothesised that adoption of USG in-plane cannulation of the BCV as the primary approach to central venous cannulation at our institution would lead to central venous cannulation for a greater variety of indications. METHODS: We performed retrospective, descriptive comparison of all central lines placed in patients aged <16 years who underwent any surgical operation during calendar years 2012-2014 at a small, free-standing children's hospital...

We used scanning tunneling microscopy to study low-angle grain boundaries at the surface of nearly planar copper nanocrystalline (111) films. The presence of grain boundaries and their emergence at the film surface create valleys composed of dissociated edge dislocations and ridges where partial dislocations have recombined. Geometric analysis and simulations indicated that valleys and ridges were created by an out-of-plane grain rotation driven by reduction of grain boundary energy. These results suggest that in general, it is impossible to form flat two-dimensional nanocrystalline films of copper and other metals exhibiting small stacking fault energies and/or large elastic anisotropy, which induce a large anisotropy in the dislocation-line energy...

In this study, we aimed to identify major fiber pathways and their spatiotemporal relationships within transient fetal zones in the human fetal brain by comparing postmortem high-angular resolution diffusion MR imaging (HARDI) in combination with deterministic streamline tractography and histology. Diffusion weighted imaging was performed on postmortem human fetal brains [N = 9, age = 18-34 post-conceptual weeks (PCW)] that were grossly normal with no pathologic abnormalities. After HARDI was performed, the fibers were reconstructed using Q-ball algorithm and deterministic streamline tractography...

Recently, the concept of small molecule activation by frustrated Lewis pairs (FLPs) has been expanded to the solid state showing a variety of interesting reactivities. Therefore, there is a need to establish a computational protocol to investigate such systems theoretically. In the present study, we selected several FLPs and applied multiple levels of theory, ranging from a semi-empirical tight-binding Hamiltonian to dispersion corrected hybrid density functionals. Their performance is benchmarked for the computation of crystal geometries, thermostatistical contributions, and reaction energies...

The arts of origami and kirigami inspired numerous examples of macroscale hierarchical structures with high degree of reconfigurability and multiple functionalities. Extension of kirigami and origami patterning to micro-, meso-, and nanoscales enabled production of nanocomposites with unusual combination of properties, transitioning these art forms to the toolbox of materials design. Various subtractive and additive fabrication techniques applicable to nanocomposites and out-of-plane deformation of patterns enable a technological framework to negotiate often contradictory structural requirements for materials properties...

The emerging popularity and wide acceptance of green chemistry and environmentally benign/ecofriendly approaches have comprehensively considered for catalyst synthesis methods. Natural resource derived carbogenic quantum dots has been used in assistance with ultrasonic shock wave to graphene oxide (GO) aqueous dispersion in order to prepare reduced graphene oxide decorated with silver nanoparticles following the 'top-down' method. The total reduction process is done without using any toxic external reducing agents and any surfactants or stabilizers, thus it can be accepted as green method...

The broken symmetry along with anomalous defect structures and charging conditions at multiferroics surface can alter both crystal structures and electronic configurations, bringing in emergent physical properties. Extraordinary surface states are induced into original mutually coupled order parameters in such strongly correlated oxides, which flourish in diverse properties but remain less explored. Here, we report the peculiar surface ferroelectric states and reconfigurable functionalities driven by the relaxation of surface and consequent changes in O 2p and Y 4d orbital (p-d) hybridization within a representative hexagonal multiferroics, YMnO3...

BACKGROUND: The recommended location of graft attachment during sacrocolpopexy is at or below the sacral promontory on the anterior surface of the first sacral vertebra. Graft fixation below the sacral promontory may potentially involve the first sacral nerve. OBJECTIVE: The objectives of this study were to examine the anatomy of the right first sacral nerve relative to the midpoint of the sacral promontory and to evaluate the thickness and ultrastructural composition of the anterior longitudinal ligament at the sacral promontory level...
