The article presents an analysis of the formation parameters microrelief artistic casting. direction for solving particular issues improving castings quality with high requirements accuracy surface relief is shown.

The question of whether impact basins dating from the time of heavy bombardment of the inner solar system are preserved on the surface of Venus is of paramount importance for an understanding of the geological processes that have shaped that planet. Two types of features have been suggested as candidates for impact basins on Venus: (1) large, quasi-circular topographic depressions and (2) large...

PURPOSE The purpose of this study was to assess the pain relief in patients with unresectable and recurrent colorectal cancer treated with radiation plus 8 MHz radiofrequency-capacitive regional hyperthermia and to identify predictors of the good outcome. METHODS Between February 1986-May 2003, 41 patients with primarily unresectable and recurrent colorectal cancer that caused pain were treat...

In this communication, we describe a simple process for the generation of surface relief gratings (SRG). SRG are fabricated from a photocross-linkable organic monomer PDACE (4-propyldiphenylacetylenecarboxylic acid cinnamyl ester) with cinnamyl ester and tolane groups, by using a patterned non-polarized UV light irradiation. The patterns of the surface relief structures can be easily controlled...

The surface relief gratings (SRGs) can be generated when azo-polymer films are exposed to laser beam interference as a result of mass migration. Despite considerable research effort over the past two decades this complex phenomenon remains incompletely understood. Here we show, for the first time, the athermal photofluidisation of azo-polysiloxane films exposed to 488 nm light, directly monitor...

with the eight sassanians reliefs, naghsh-e rustam in marvdasht is a prominent complex safeguarding a complete collection of the sassanian period. seven of these reliefs have been repeatedly the subject of investigations thanks to their relatively better conditions. the fifth relief, however, has not yet been studied due to their damaged status. it depicts the full-face portrait of a sassanid k...

Transfer printing is an important and versatile tool for deterministic assembly and integration of micro/nanomaterials on unusual substrates, with promising applications in fabrication of stretchable and flexible electronics. The shape memory polymers (SMP) with triangular surface relief structures are introduced to achieve large, reversible adhesion, thereby with potential applications in temp...

In this work the Monte Carlo method with an empirical potential model for atomic interactions is applied to study reconstruction and intermixing at a Ge-covered Si~001! surface. We investigate the structure and energetics of the 23n reconstruction which serves as a strain-relief mechanism. The optimal value of n is found to be strongly dependent on the thickness of the Ge overlayer. Si-Ge inter...
