The high-mobility group (HMG) box defines a DNA-bending motif of broad interest in relation to human development and disease. Major and minor wings of an L-shaped structure provide a template for DNA bending. As in the TATA-binding protein and a diverse family of factors, insertion of one or more side chains between base pairs induces a DNA kink. The HMG box binds in the DNA minor groove and ma...

Effects of the heat treatment parameters were evaluated relative to some physical and mechanical properties poplar wood (Populus alba L.) with use two prominent multi criteria decision-making (MCDM) techniques: Entropy The Technique for Order Preference by Similarity Ideal Solution (TOPSIS). To meet this objective, test samples heat-treated at 120, 150, 180, 210 °C 2 4 h in a laboratory-scale o...

This is the first part of a two-part paper dedicated to a new plate theory for out-of-plane loaded thick plates where the static unknowns are those of the Kirchhoff-Love theory (3 in-plane stresses and 3 bending moments), to which six components are added representing the gradient of the bending moment. The new theory, called the Bending-Gradient plate theory is described in the present paper. ...

This work describes the design, implementation and first results of a fatigue test rig capable of subjecting cylindrical specimens of different sizes and materials to complex real-life loading conditions. The resulting test rig can be used to combine a rotating bending load with a fluctuating torsional load. Due to a closed electromechanical loop, power consumption is limited and a maximum test...

Present study was performed to investigate the impact of sublethal concentrations of Diazinon on different behavioral aspects of Labeo rohita. LC50 of Diazinon for 96 hrs by static bioassay test was found to be 0.004ml/l. The fishes were exposed for 96 hrs. Diazinon exposure caused decrease in resting period, increase in opercular movement and air gulping, increase in jerk, threat and burst swi...

In this study, the spanwise and chordwise bending stiffness EI of honeybee forewings were measured by a cantilevered bending test. The test results indicate that the spanwise EI of the forewing is two orders of magnitude larger than the chordwise EI Three structural aspects result in this span-chordwise bending anisotropy: the distribution of resilin patches, the corrugation along the span and ...

Dynamic three-point bend tests are performed on small beams specimen made of a quasi-brittle material. The most classical hypotheses needed to analyse the tests with SHPB, which are based on a state of quasi-static balance of the body, cannot be used. In order to get the behaviour it is necessary to perform a transient analysis of the specimen response. In most cases, the useful duration of the...

The aim of this study was to investigate the effect of loading rate on the micro-mechanical properties of oak (Quercus petraea) wood. Bending strength, modulus of elasticity in bending, compression strength parallel to the grain and tensile strength parallel to the grain were determined using microsized test samples. Three different loading rates were used for each test. The first loading rates...

During their development, plants are subjected to repeated and fluctuating wind loads, an environmental factor predicted to increase in importance by scenarios of global climatic change. Notwithstanding the importance of wind stress on plant growth and development, little is known about plant acclimation to the bending stresses imposed by repeated winds. The time-course of acclimation of young ...
