Tooth root crack is considered as one of the crucial causes of failure in the gearing system and it occurs at the tooth root due to an excessive bending stress developed in the root region. The modern power transmission gear drives demand high bending load capacity, increased contact load capacity, low weight, reduced noise and longer life. These subsequent conditions are satisfied by the aid o...

Type IIA topoisomerases modify DNA topology by passing one segment of duplex DNA (transfer or T-segment) through a transient double-strand break in a second segment of DNA (gate or G-segment) in an ATP-dependent reaction. Type IIA topoisomerases decatenate, unknot and relax supercoiled DNA to levels below equilibrium, resulting in global topology simplification. The mechanism underlying this no...

DNA bending plays an important role in many biological processes, but its molecular and energetic details as a function of base sequence remain to be fully understood. Using a recently developed restraint, we have studied the controlled bending of four different B-DNA oligomers using molecular dynamics simulations. Umbrella sampling with the AMBER program and the recent parmbsc0 force field yie...

Introduction: Scoliosis is a lateral spinal deformity of 10 degrees or more, resulting in a C-shaped or S-shaped curve of the spine. Information about adolescent idiopathic scoliosis (AIS) prevalence rate is important not only for paediatric health care planning strategy but also for parent's awareness. This study aims to find the suitable inclination cut-off angle and the prevalence rate of AI...

A combination of simulations and Fourier transform infrared spectroscopy was used to examine the effect of three ionic solutes ~KCl, NaCl, and KSCN!, the polar solute urea, and the osmolyte trimethylamine-N-oxide ~TMAO! on a water structure. The ionic solutes increase the mean water– water H-bond angle in their first hydration shell concomitantly shifting the OH stretching mode to higher freque...

Actual applications of the energy absorbers showed that actual loads are not applied in the form of pure axial compression, pure bending or pure torsion. In reality, an energy absorber component may be subjected to combined loading of compression, bending and torsion. A number of previous articles have investigated the behavior of energy absorbers under oblique loading. In such cases, the obliq...

This paper presents a fully printable sensorized bending actuator that can be calibrated to provide reliable bending feedback and simple contact detection. A soft bending actuator following a pleated morphology, as well as a flexible resistive strain sensor, were directly 3D printed using easily accessible FDM printer hardware with a dualextrusion tool head. The flexible sensor was directly wel...

Geometric effects play an important role in laser forming process; however, few investigations have been reported on the geometric size effect other than sheet thickness. In this paper, the influence of size effect, including sheet width and sheet length, on laser induced deformation is experimentally, numerically and analytically investigated. A size matrix is designed to cover a wide range of...

After being processed into a certain shape by stirrup bending machine, steel bars are used as the skeleton of reinforced concrete in construction. The accuracy their directly affects bearing capacity concrete. In order to improve springback angle after bending, this paper focuses on optimizing structural parameters bar machine and controlling bars. influence support shaft diameter, crankshaft r...
