How hydrophobicity (HY) drives protein folding is studied. The 1971 Nozaki-Tanford method of measuring HY is modified to use gases as solutes, not crystals, and this makes the method easy to use. Alkanes are found to be much more hydrophobic than rare gases, and the two different kinds of HY are termed intrinsic (rare gases) and extrinsic (alkanes). The HY values of rare gases are proportional ...

Organisms that are durophagous, hard prey consumers, have a diversity of tooth forms. To determine why we see this variation, we tested whether some tooth forms break shells better than others. We measured the force needed with three series of aluminium tooth models, which varied in concavity and the morphology of a stress concentrating cusp, to break a shell. We created functionally identical ...

We report the discovery of nineteen new H i shells in the Southern Galactic Plane Survey (SGPS). These shells, which range in radius from 40 pc to 1 kpc, were found in the low resolution Parkes portion of the SGPS dataset, covering Galactic longitudes l = 253 to l = 358. Here we give the properties of individual shells, including positions, physical dimensions, energetics, masses, and possible ...

Layer-by-layer self-assembled polyelectrolyte shells are a new class of micro/nanocapsules with unique physicochemical properties for potential applications in drug/gene delivery. The objective of this study was to investigate the interactions of polyelectrolyte shells ( approximately 1 mum in diameter) with MCF-7 breast cancer cells and identify key parameters that affect such interactions. Ta...

The article considers the problem of a rectangular plate, supported by cross system stiffening ribs, bending. In addition to transverse load, plate is subjected forces in its plane, transmitted through ribs. Аn analytical solution boundary value for resolving differential equation with respect normal deflection describing deformation stiffeners, obtained. presented form series combinations regu...

In the present article, we revisit question of structural characteristics and building methods two most famous Hungarian Late-Gothic net vaults, nave vault Franciscan Church Szeged-Alsóváros Reformed Nyírbátor. Based on data gathered by laser-scanning buildings, geometric system as opposed to former state research, differ significantly from each other. While rib webbing have features characteri...

Elastic spherical shells loaded under uniform pressure are subject to equal and opposite compressive probing forces at their poles to trigger and explore buckling. When the shells support external pressure, buckling is usually axisymmetric; the maximum probing force and the energy barrier the probe must overcome are determined. Applications of the probing forces under two different loading cond...
