in order to help in the engineering design of rice harvesting machines, there is a need to have exact information concerning the physical and mechanical properties of rice stems. the cutting force for rice stems, therefore, was measured by designing and fabricating a static and dynamic shear test apparatus. the effects of moisture levels and the cross-sectional area of stem as well as the varie...

Estimation of the fast polarization direction of shear seismic waves that deviate from horizontal axis is a valuable approach to investigate the characteristics of the lower crust and uppermost mantle structures. The lattice preferred orientation of crystals, which is generally parallel to the downward or upward flow of the mantle or crust, is an important reason for the occurrence of fast axis...

Fingernails are a characteristic anatomical feature of primates and their function is dictated by the environment in which they are utilised. The present study examined the mechanical properties of human fingernails as a function of relative humidity (RH) and the subsequent moisture content of the nail material. Nail clippings were stored at a range of RH values and then weighed in order to det...

Electrical injection of magnetic domain walls in perpendicular magnetic anisotropy nanowire is crucial for data bit writing in domain wall-based magnetic memory and logic devices. Conventionally, the current pulse required to nucleate a domain wall is approximately ~10(12) A/m(2). Here, we demonstrate an energy efficient structure to inject domain walls. Under an applied electric potential, our...

• A weak magnetic field can enhance ductile-mode cutting of CaF 2 single crystal. Magnetic direction shows anisotropy in affecting ductile–brittle transition. coupled analysis magneto-plasticity and crystal plasticity is developed. Dislocation behaviour fracture toughness are revealed under field. DFT computation corroborates the magnetic-induced dislocation depinning theory. Magneto-plasticity...

The goal of this study is to clarify the relationship between quantitative ultrasonic measurements (QUS), bone mineral density (BMD) and micro architectural parameters (reflecting morphology, connectivity and anisotropy) measured on human proximal femur. BMD was determined using X-ray quantitative computed tomography (QCT) and micro architecture was investigated using synchrotron radiation micr...

Abstract The scaling of magnetic fluctuations provides crucial information for the understanding solar wind turbulence. However, observed contain not only turbulence but also structures, leading to violation time stationarity. This would conceal true and influence determination sampling angle with respect local background field. Here, investigate anisotropy, we utilize a simple effective criter...

Drill mud is a fluid which is used in oil extraction industries in order to cool and lubricate the drill bit. Due to containing numerous toxic components, it is considered as a hazardous waste which must be treated before discharging to the environment. Current separation techniques for drill cutting treatment can be categorized into three main categories of physical (dewatering), physiochemica...

Fibre reinforced plastic composite materials are difficult to machine because of the anisotropy and inhomogeneity characterizing their microstructure and the abrasiveness of their reinforcement components. During machining, very rapid cutting tool wear development is experienced, and surface integrity damage is often produced in the machined parts. An accurate selection of the proper tool and m...
