The effect of liquid compressibility in the two-stage piston hybrid positive-displacement machine with a was considered. Based on volume conservation equation, we developed calculus methodology for during gas compression second stage compressor section. A numerical experiment made it possible to establish that some parameters have greatest relative decrease height and velocity layer. These are ...

We propose to circumvent this mathematical integration procedure wd Indead jobtain the macroscopical behavior directly from the microscopical laws through fimulation with an analogical representation. Our purpose is to construct a representation of liquids which can reproduce macroscopical qualitatively oorrocx behrvio of liquids . A model like ours, bused on simple local interattion laws, is w...

BACKGROUND/AIMS Macular translocation with scleral imbrication is a new technique for treating subfoveal choroidal neovascular membranes (CNV). This procedure shortens the sclera but may result in a minimal decrease in the internal circumference of the globe and limits the amount of foveal displacement. The authors propose a new scleral retraction suture aimed at decreasing the internal circumf...

We optically generated and observed GHz ultrasonic waves on liquid surfaces and a liquid/liquid interface for the first time using the transient reflecting grating ~TRG! method. Four kinds of samples were used for measurement of the surfaces; two types of black ink, an aqueous solution of crystal violet ~CV aq solution! and ethanol aqueous solutions of CV. A cyclohexane/CV aq solution interface...

Strand displacement by a DNA polymerase serves a key role in Okazaki fragment maturation, which involves displacement of the RNA primer of the preexisting Okazaki fragment into a flap structure, and subsequent flap removal and fragment ligation. We investigated the role of Sulfolobus chromatin proteins Sso7d and Cren7 in strand displacement by DNA polymerase B1 (PolB1) from the hyperthermophili...

A novel stereocamera has been developed based on the angular-displacement method, wherein the two camera axes are oriented in a nonorthogonal manner toward the object plane. The stereocamera satisfies the Scheimpflug condition such that the image plane, the object plane, and the lens plane are nominally colinear. A unique feature of the stereocamera is the introduction of a liquid prism between...

The goal of this article is the application of the finite element method to study and simulate the unique behaviors of liquid crystal elastomers, such as semi-soft elasticity and stripe-domain instability. We start with an energy functional that consists of the Bladon-Warner-Terentjev stored energy of the liquid crystal elastomer, the Oseen-Frank energy of liquid crystals, plus Lagrange multipl...

A concept of accurate liquid viscosity sensing, using bulk acoustic wave (BAW) resonators, is proposed. The proposed BAW resonators use thin ferroelectric films with the dc field induced piezoelectric effect allowing for generation of pure longitudinal acoustic waves in the thickness excitation mode. This makes it possible to utilize exclusively shear liquid particle displacement at the resonat...
