Ectoine-mediated protection of enzyme from the effect of pH and temperature stress: a study using Bacillus halodurans xylanase as a model

In this work, the protective effect of ectoines against pH stress and high temperature has been investigated using an alkaline active xylanase from Bacillus halodurans as a model. The disaccharide, trehalose—a well-known stabiliser for biomolecules (Kaushik and Bhat 2003), has also been included in the study. The enzyme was selected as a model because it is efficiently active at high pH and is highly stable in the pH range of 5.5–10.5 at 50 °C.

Fracture of high performance materials under multiaxial compression and thermal effect

The article discusses the strength of concrete and other brittle materials in the case of nonuniform biaxial type of compression (σ1 > σ2 > 0) and triaxial compression of σ1 > σ2 = σ3 > 0 type (it was assumed that σ> 0 corresponds to compression). I

Extension of linear elastic strain energy density approach to high temperature fatigue and a synthesis of Cu-Be alloy experimental tests

The present paper summaries the results from uniaxial-tension stress-controlled fatigue tests performed at different temperatures up to 650°C on Cu-Be specimens. Two geometries are considered: hourglass shaped and plates weakened by a central hole (Cu-Be alloy).

Báo cáo khoa học: CAP2 enhances germination of transgenic tobacco seeds at high temperature and promotes heat stress tolerance in yeast

We reported earlier that ectopic expression of CAP2, a single AP2 domain containing transcription activator from chickpea (Cicer arietinum)in tobacco improves growth and development, and tolerance to dehydration and salt stress, of the transgenic plants.

Wear mechanisms of HSS cutting tools

Metal cutting puts extreme demands on the tool and tool material through conditions of high forces, high contact pressures, high temperatures, and intense chemical attack by difficult to cut work materials. In addition, the tool geometry and cutting conditions in terms of sharp edges, cyclic engagement and presence of cutting fluid will add to the severity. Most often cutting tools are used close to their ultimate resistance against these loads, especially to the limiting thermal and mechanical stresses. ...
