We observe quasistatic deformation of lipid vesicles from within, due to the polymerization of confined microtubules. A pair of long, narrow membrane sleeves appears, sheathing the microtubule ends as they grow. Spontaneous buckling reveals that the force generated can be greater than 2 pN. The evolution of shape and magnitude of force are consistent with a simple theory for the membrane free e...

This paper describes a new species of the millipede genus Streptogonopus Attems, 1914, Streptogonopus montanus sp. n. from Vietnam, the first record of Streptogonopus in Vietnam. The new species is characterised by the solenophore completely sheathing the solenomere, both coiled twice, and the solenophore with a small spine at its middle. The species was found at ca. 1,800-2,100 m on Ngoc Linh ...

Background: Contamination of work surfaces by used laryngoscopes after endotracheal intubation is a serious infection control concern but no strategies are available to address it. We assessed if contamination the would be reduced when providers dedicated, self-erected, disposable plastic sleeve (BladePouch) store laryngoscope as compared using single gloves or double and sheathing with outer g...

Abstract The optimisation of the cross sectional geometry cold-formed steel sections has been subject numerous past studies. These walls consist intermittently placed studs, lined most commonly with gypsum plasterboards. Experimental evidence shown that restraints provided by wall sheathing can have a significant impact on axial compression capacity these studs. However, studies incorporating i...

The sheathing-to-timber connection (STC) is a critical component of timber-framed shear walls. STC provides the wall system with its racking resistance, while anchors and tiedowns provide resistance to sliding overturning, respectively. Because building materials are exposed weathering during construction, this study aims quantify influence on structural performance STCs. To achieve aim, total ...

Injuries with used needles and other "sharps" put health care workers at risk for serious bloodborne infections, such as HIV and hepatitis B and C. To some extent, this risk can be lessened through safer techniques (such as not recapping needles) and safer devices (such as needleless and self-sheathing equipment). But these injuries occur within a context (often a hospital unit) with organizati...
