In the present paper the thermodynamic and phenomenological descriptions of the crossflow piezo-electrooptic effect in crystals have been made. For example the necessary experimental measurements of this effect have been carried out in the lithium tantalate crystals. For these crystals at first the P33113−P11113 = −4.6·10 m/ N·V absolute coefficients difference of crossflow piezo-electrooptic e...

We present an all-magnetic scheme for the assembly and study of magnetic dipoles within designed confinement profiles that are activated on micro-patterned permalloy films through a precessing magnetic field. Independent control over the confinement and dipolar interactions is achieved by tuning the strength and orientation of the revolving field. The technique is demonstrated with superparamag...

Sperm immobilization prior to intracytoplasmic sperm injection (ICSI) is thought to be necessary for efficient fertilization. A variety of methods of sperm immobilization (pipetting, squeezing and piezo application) are currently employed in ICSI. The effect of differences in immobilization method on the timing of initial Ca(2+) oscillations of oocytes in ICSI was investigated. Motile spermatoz...

A sequence stratigraphic study of terrigenous and carbonate rocks of the Infra Krol Formation and Krol Group in the Lesser Himalaya fold and thrust belt of northern India was undertaken as part of a broader investigation of the significance of carbon isotope data in Neoproterozoic successions. Eight regional stratigraphic discontinuities were traced over a distance of nearly 300 km, and interpr...

Two isomorphous anionic metal dicyanamide extended systems [Cu(pCTH)][M(dca)(4)] (M = Mn(II), Co(II); dca = dicyanamide; pCTH = 5,7,7,12,14,14-hexamethyl-1,4,8,11-tetrazacyclotetradecane-4,11-diene) have been prepared through [Cu(pCTH)](2+) templation and characterized by X-ray crystallography and magnetic measurements. In these complexes, the [M(dca)(4)](2)(-) anions form 2D (4,4) distorted sq...

The teeth of the Polyplacophora Chiton Acanthochiton Rubrolinestus contain biomineralized magnetite crystallites whose biological functions in relation to structure and magnetic properties are not well understood. Here, using superconducting quantum interference device (SQUID) magnetometry, we find that the saturation magnetization (σ(s)) and the Verwey transition temperature (T(v)) of tooth pa...

In the crystal structure of the title compound, C(11)H(10)N(2)O·H(2)O, the solvent water mol-ecule links the organic mol-ecules through O-H⋯O and O-H⋯N hydrogen bonds, forming chains that run diagonally across the bc face. These chains are connected to adjacent chains through weak C-H⋯O inter-actions, resulting in hydrogen-bonded sheets extending along the b and c axes. The sheets are connected...

In an electrically conducting fluid, vortices stretch out a weak, large-scale magnetic field to form strong current sheets on their edges. Associated with these current sheets are magnetic stresses, which are subsequently released through reconnection, leading to vortex disruption, and possibly even destruction. This disruption phenomenon is investigated here in the context of two-dimensional, ...

The aim of this study was to evaluate histomorphometrically the influence of two techniques of dental implant site preparation on bone healing around titanium implants. Fifteen male Wistar rats (±300 g) were used in the study. Each tibia was randomly assigned to receive the implant site preparation either with a conventional drilling technique (control - DRILL group) or with a piezoelectric dev...
