The diagnostic and clinical usefulness of a powered bone marrow biopsy device (OnControl()) versus a standard manual device (TRAP Hospital System) was studied. Primary endpoints were biopsy quality and patient pain during the procedure. Fifty patients underwent a total of 60 procedures by three expert operators in a randomised stratified fashion. Baseline demographic and clinical parameters wer...

Under special conditions bacteria excrete an attractant and aggregate. The high density regions initially collapse into cylindrical structures, which subsequently destabilize and break up into spherical aggregates. This paper presents a theoretical description of the process, from the structure of the collapsing cylinder to the spacing of the final aggregates. We show that cylindrical collapse ...

Background & Aims of the Study: Needle stick injuries (NSIs) are one of the most causes that expose health care workers (HCWs) to blood infectious diseases such as hepatitis B, C and HIV. HCWs can reduce the rate of NSIs by performing protective procedures. This study was conducted to evaluate the needle stick exposure among health care workers in Razi hospital, Ahvaz, in 2015....

When a human grasps a cylindrical object, feedback on the orientation of the cylinder with respect to the axes of the digits is crucial for successful manipulation of the object. We measured the ability of humans to discriminate the orientations of cylinders passively contacting the fingerpad. For a cylinder of curvature of 521 m-1 (radius, 1.92 mm) subjects were able to discriminate, at the 75...

Local convective heat transfer coefficients were measured on a two-diameter long cylinder in axial flows of air at conditions unexplored so far, by using thermochromic liquid crystals (TLC) coated on an electrically heated strip-foil consisting bonded to the external surfaces. The Reynolds numbers (Re) based on the cylinder diameter were between 8.9 · 10 and 6.17 · 10, and the flow in front of ...

We demonstrate that the temperature-dependent phase behaviors of parallel and perpendicular cylinder-forming block copolymers are governed by domain-domain segregation forces inherently present in block copolymer material itself. With increasing temperature, a parallel cylinder-forming block copolymer experienced a parallel cylinder straightening process before the order-disorder transition (OD...

The lubrication form of the equations governing the flow of a thin liquid film on a horizontal right circular cylinder is derived. The equations are discretized and solved numerically using an alternating-direction implicit algorithm. Simulations demonstrate that the transition from a uniform coating to a final configuration of distinct drops follows a similar evolution for a wide range of cyli...

fine needle aspiration (fna) technique is a well-known procedure in the diagnosis of various organ diseases. this study was conducted to evaluate the utility of fna in the dianosis of neck masses. fine needle aspiration was performed upon 123 patients with palpable nonthyroidal lesions at neck during a five-year period. in ten cases, fna findings were nondiagnostic. from the reminder 113 patien...

many studies have been accomplished on the subject of cyrus cylinder inscription, but mythological role of mesopotamian nabu on this cylinder has not been properly studied. the cylinder is damaged on some parts and nabu and marduk are the only remained god-names in the inscription. nabu was the god of writing, wisdom, and to some extent happiness who protected scribes and was believed to be the...
