Temperature control during the cutting process with different parameters such as cutting velocity and applying water cooling is essential to decrease the cutting force, increase the life of the cutting tool and decrease the machined surface temperature of work-piece. In this research, the temperature of machined surface and the chip-tool interface in orthogonal cutting process of Ti-6Al-4V were...

In this paper results are presented from a simple offline assimilation system that uses radiances from the Moderate Resolution Imaging Spectroradiometer (MODIS) channels that sense atmospheric aerosols over land and ocean. The MODIS information is directly inserted into the Goddard Chemistry and Aerosol Radiation Transport model (GOCART), which simulates the following five aerosol types: dust, ...

The effect of soil surface roughness on runoff and sediment production is an area not yet fully quantified. Current erosion prediction models, such as the Revised Universal Soil Loss Equation, predicts a reduced erosion from an increased soil roughness, without considering the functionality associated with different roughness forms. In this research, we used a mechanistic approach in which soil...

In this study, PDMS (polydimethylsiloxane) substrates with a half-plain, half-rough surface were prepared on a plain and rough fused silica glass substrate using a molding technique. The molded PDMS surface morphology was changed into a half-smooth and half-rough surface after peeling. The modified PDMS surfaces’ optical properties were inspected with and without treatment. The treatment is exp...

Micro manipulations of objects between 10μm and 1mm by contact are often disturbed by adhesion between the handled object and the gripper. This is due to the presence of the surface forces which overcome gravity and prevent the release of the object. Capillary, electrostatic and van der Waals forces are the main surface forces responsible for this adhesive phenomenon. Several factors may influe...

The relative roles of volume and surface nucleation were investigated for the homogeneous freezing of pure water droplets. Experiments were carried out in a cryogenic laminar aerosol flow tube using supercooled water aerosols with maximum volume densities at radii between 1 and 3 μm. Temperatureand size-dependent values of volumeand surface-based homogeneous nucleation rates between 234.8 and 2...

THE MYOFIBROBLAST Myofibroblasts are modified fibroblasts which were first identified in granulation tissue, where they are probably derived from local fibroblasts, and which form the principal component of a number of reactive and benign soft tissue lesions. Under mechanical stress, the fibroblasts acquire cytoplasmic actin-containing microfilaments or stress fibres which express β−and γ-actin...

Based on experimental data acquired with particle image velocimetry, we examine turbulent boundary layers that are subjected to an abrupt change in wall roughness the streamwise direction. Three different sandpapers (P24, P36 and P60) together a smooth used form number of surface transition cases, including both R $\rightarrow$ S (where upstream is rough second either or smoother compared surfa...

Purified plasma membranes, smooth and rough endoplasmic reticulum, and nuclei were prepared from the livers of rats made either hyperinsulinemic with insulin injections or hypoinsulinemic with streptozotocin. Plasma membranes from insulin-treated animals bound 46% less lz51-insulin, and membranes from diabetic animals 33% more labeled hormone, than membranes from controls. Binding plots indicat...
