We report a new nonaqueous polymerization-induced self-assembly (PISA) formulation based on the reversible addition-fragmentation chain transfer (RAFT) dispersion alternating copolymerization of styrene with N-phenylmaleimide using a nonionic poly(N,N-dimethylacrylamide) stabilizer in a 50/50 w/w ethanol/methyl ethyl ketone (MEK) mixture. The MEK cosolvent is significantly less toxic than the 1...

Iodine molecules confined in the elliptical nanochannels of AlPO4-11 crystals can only rotate in the plane passing through the major axis of the elliptical cross-section due to size confinement. This leads to different dynamic behaviors of iodine from those confined in round channels of AlPO4-5 crystals under ambient conditions. In this work, we use high pressure technology to manipulate the na...

A mathematical model for computing stresses in sutured human skin wounds is presented. The model uses the incremental law of elasticity and elastic constants valid for in vivo orthotropic skin. The model is applied to compute the principal stress and displacements resulting from suturing small elliptical and circular wounds in a large at sheet of skin, in order to determine the optimal suturing...

Analysis of equilibrium conditions was carried out and resonant precessional dynamics magnetization a single-domain magnetically uniaxial ellipsoidal particle. Considered the case when magnetic field is along easy axis. axis directed parallel to symmetry ellipsoid transverse pumping by weak high-frequency field. Features behavior were discovered. It has been revealed that features behavior: lar...

A kinetic fluorometric method was proposed for the quantitative determination of epinephrine (EP) in human plasma samples with the aid of second-order calibration methods based on alternating trilinear decomposition (ATLD) and alternating fitting residue (AFR) algorithms. It was based on that EP could be gradually converted to a highly fluorescent intermediate product by an oxidation reaction, ...

Well-preserved holdfasts and early growth stages of the tubular cnidarian Sphenothallus are described from Silurian (Llandovery Series) Washington Land, North Greenland. The diameter holdfast is determined by formation a basal disc attached to substrate, upon which initially conical, but subsequently shell formed. characteristic opposing longitudinal thickenings developed at each angular margin...

Ah&met-The boundary element method is used to analyze the ACPD (alternating current potential drop) field perturbed by a semi-elliptical surface flaw in a metallic sheet. The depth of the penetration of the alternating current is assumed to be small as compared to the crack depth. This allows us to adopt the “unfolding” technique developed by Dover et al. [ASTM STP 722, 401-427 (1981)], which r...

The main objective of this study is to investigate the fluid flow and heat transfer around a bundle of tubes with elliptical cross-section. The studied parameters include the shape of the tubes, presence or absence of blades, tube configuration, thermal boundary conditions, surface boundary conditions (such as surface roughness), fluid temperature and fluid velocity. Therefore, to investigate h...
