BACKGROUND AND PURPOSE Various laparoscopic devices have been described for suture anchoring during solidorgan parenchymal closure. Application of these devices expedites the closure of parenchymal defects and minimizes ischemia time. We compared different technologies as suture anchors for parenchymal closure. MATERIALS AND METHODS A tensometer was used to determine the amount of tension nec...

Four patients with intracranial aneurysm clips made from a variety of alloys were studied without incidence by MR imaging at field strengths ranging from 0.35 to 0.6 T. Knowledge of the type of alloy used in the manufacturing of an aneurysm clip is important in determining whether the clip will or will not deflect in a magnetic field. Ferromagnetic clips show deflection and torque in a magnetic...

Biliary extraction baskets are a commonly used instrument for the removal of choledocholithiasis in endoscopic retrograde cholangiopancreatography (ERCP). Impaction of the extraction basket is a recognized complication of ERCP, and is usually the result of discrepancy between the size of bile duct stone and the diameter of the distal bile duct. Whilst mechanical lithotriptors can be used to cru...

We advance a quantitative description of the critical shear rate γ̇c needed to dislodge a spherical particle resting on a surface with a model asperity in laminar and turbulent fluid flows. We have built a cone-plane experimental apparatus which enables measurement of γ̇c over a wide range of particle Reynolds number Rep from 10−3 to 1.5 × 103. The condition to dislodge the particle is found to b...

Two techniques for quantitatively recovering normal-flora microorganisms from the skin of infants were compared. A technique using a swab to dislodge microorganisms from the skin compared favorably to a technique using a rubber policeman. The swab was easier to use and is suitable for use on infant skin.

Emergent Actors is an excellent book. At its core is what I would view as a rightminded attempt to dislodge the state from the sacred spot it holds in international relations (IR) theory. Drawing liberally on literatures of development, IR theory and philosophy of science it lays out a methodology to deconstruct and then reconstruct the state, outlining a modelling approach that I hope will be ...

Since FOX-7 (1, 1-diamino-2, 2-dinitroethylene) is a relatively new energetic material, little is known about its physical and chemical properties. Therefore, first-principles quantum chemical calculations are used to predict the energies of atoms of FOX-7. Under gentle heating (thermolysis) is likely to cause hydrogen transfer between molecules, producing highly reactive chemical species. Conv...

Our body needs food everyday that supplies all the nutrients in required amount to keep the body healthy. But eating of food sometimes gets affected by socio- cultural factors that condition the dietary habits of the people which contribute significantly to nutritional deprivation in the communities, these faulty feeding habits arising from ignorance, superstitions, and social prejudices have b...
