In Reply: We thank Xue et al. for their recent letter regarding our recent article and are happy to respond to their questions and comments. Their first question related to the number of neonates included in the study. We had two neonates in our study; one was randomized to the GlideScope (Verathon Medical, Bothell, WA) and the other to direct laryngoscopy (Heine, Dover, NH). We routinely use a...

Fixation with a dynamic hip screw (DHS) is one of the most common methods for stabilizing intertrochanteric fractures, except for unstable and reverse oblique fracture types. However, failure is often observed in osteoporotic patients whereby the lag screw effectively 'cuts out' through the weak bone. Novel anti-migration blades have been developed to be used in combination with a lag screw ('B...

Involvement of cervical spine in ankylosing spondylitis limits neck movement resulting in difficult intubation. We report a case of 45-yr-old lady of ankylosing spondylitis with restricted neck movement planned for emergency laparotomy. Grade 3 Cormack and Lehane laryngoscopic view was observed with Macintosh laryngoscope and gum elastic bougie could not be negotiated. At second attempt with Mc...

Listeria monocytogenes has been implicated in several listeriosis outbreaks linked to the consump tion of presliced ready-to-eat (RTE) deli meats, which has drawn considerable attention in regard to possible cross-contamination during slicing operation at retail and food service environments. Salami with 15% fat (a moderate l fat content deli item) was used to investigate the transfer of L. mon...

The leaf blade of cotton (Gossypium hirsutum L. cv. Stoneville 213) was investigated as the initial site of ethylene action in abscission. Ethylene applied at 14 mul/l to intact 3-week-old plants caused abscission of the third true leaf within 3 days. However, keeping only the leaf blade of this leaf in air during ethylene treatment of the rest of the plant completely prevented its abscission f...

The aim of the present study was to find a more optimal blade design for rowing performance than the Big Blade, which has been shown to be less than optimal for propulsion. As well as the Big Blade, a flat Big Blade, a flat rectangular blade, and a rectangular blade with the same curvature and projected area as the Big Blade were tested in a water flume to determine their fluid dynamic characte...

The throughflow level of approximation still remains an important tool for designing turbomachines [2] even though 3-D calculations are used more and more early in the design process. The throughflow models heavily rely on empirical inputs such as 2-D correlations or end-wall loss models. This feature has shown to be efficient but lack of generality. Two-dimensional empirical correlations are a...

The surface of gutta-percha cones was evaluated after using five different cutting methods, including a new TipSnip device. The gutta-percha cones were cut off using: 1) TipSnip, 2) a single cut with a scalpel blade using a gauge, 3) two cuts with a scalpel blade using a gauge, 4) a razor blade against a glass slab or 5) scissors. Samples were examined under stereomicroscopy and observed by thr...

Diffusion-weighted (DW) imaging is widely used in clinical imaging. To address the strong distortion encountered in EPI-based DW techniques, split-blade DW-PROPELLER [1] was proposed. With PROPELLER, when imaging a small Field of View (FOV) of a large object, No-Phase-Wrap (NPW) is usually applied to remove aliased signal in each blade before combining them [2]. However, with this conventional ...

In this article, a dysfunctional rotor blade belonging to a 3-MW Ruston PT-85ME steam turbine is analyzed from mechanical and metallurgical perspectives. First, using the quant metric method, the chemical composition of the alloy is determined at several parts of the blade.Then, in order to model the blade, the points of the airfoil curve are obtained using CMM (Coordinate Measuring Machine) an...
