Beverage emulsions are systems that are composed of two liquids including oil and water which are prepared by homogenizing oil phase in an acidic aqueous phase. They must be stable in both concentrated and diluted form for a period of 6-12 months upon standing at room temperature. Two immiscible phases contained systems are thermodynamically unsta-ble. In other words, they are vulnerable to bre...

Mesogenic chiral esters of optically active (S)-l,2-propanediol and (R,R)-2,3-butanediol were synthesized. The compounds, added to a nematic phase induce cholesteric phases exhibiting a helix inversion with temperature variation. This effect is independent of the molecular structure of the nematic solvent. The inversion temperature varies only slightly with concentration but can be influenced b...

In situ forming implants (ISFIs) have shown promise in drug delivery applications due to their simple manufacturing and minimally invasive administration. Precise, reproducible control of drug release from ISFIs is essential to their successful clinical application. This study investigated the effect of varying the molar ratio of different molecular weight (Mw) poly(D,L-lactic-co-glycolic acid)...

New automatic algorithm for segmentation of myocardial scar in both inversion recovery and phase sensitive inversion recovery late gadolinium enhancement: validation against TTC and in multi-center, multi-vendor patient data Jane Tufvesson, Robert Jablonowski, Henrik Engblom, Marcus Carlsson, Anthony H Aletras, Pavel Hoffmann, Alexis Jacquier, Frank Kober, Bernhard Metzler, David Erlinge, Dan A...

In a recent Letter [Opt. Lett. 25, 132 (2000)] the properties of two different techniques for time reversal of ultrafast optical waveforms were compared. Although both techniques, spectral phase conjugation and spectral inversion, perform the same function for real pulses, for pulses with complex envelope functions it was asserted that only spectral inversion gives true time reversal. I argue h...

We introduce a novel approach to three-dimensional gravity inversion in the presence of sediment-basement interface with strong density contrast. This makes it possible incorporate known information about basement depth inversion. It also allows user determine depth-to-basement initial phase. One can then use this constrain final First, generates model based on 3D Cauchy-type integral represent...

We extend the approach underlying the well-known Dix equation in reflection seismology to surface waves. Within the context of surface wave inversion, the Dix-type relation we derive for surface waves allows accurate depth profiles of shear-wave velocity to be constructed directly from phase velocity data, in contrast to perturbational methods. The depth profiles can subsequently be used as an ...

Precipitating versions of the quasigeostrophic (QG) equations are derived systematically, starting from the equations of a cloud-resolving model. The presence of phase changes of water from vapor to liquid and vice versa leads to important differences from the dry QG case. The precipitating QG (PQG) equations, in their simplest form, have two variables to describe the full system: a potential v...

Purpose: Myocardial delayed enhancement (MDE) is commonly used to assess viability of myocardial tissue. An ECG gated, segmented inversion recovery (IR) fast gradient recalled echo (FGRE) or a steady-state free precession (SSFP) sequence is used for imaging, 15-20 minutes after administration of Gadolinium-based contrast. Multiple slices are typically acquired in successive breath-holds. Single...
