Casimir forces of massive ferrnionic Dirac fields are calculated for parallel plates geometry in spatial space with dimension d and imposing bag model boundary conditions. It is shown that in the range of ma>>l where m is mass of fields quanta and a is the separation distance of the plates, it is equal to massive bosonic fields Casimir force for each degree of freedom. We argue this equalit...

The new exact formulas for the attractive Casimir force acting on each of the two identical perfectly conducting plates moving freely inside an infinite perfectly conducting cylinder with the same cross section are derived at zero and finite temperatures by making use of the zeta function technique. The long and short distance behaviour of the plates' free energy is investigated.

The effective interaction between charged colloidal particles confined between two planar like-charged walls is investigated using computer simulations of the primitive model describing asymmetric electrolytes. In detail, we calculate the effective force acting onto a single macroion and onto a macroion pair in the presence of slitlike confinement. For moderate Coulomb coupling, we find that th...

We investigate theoretically the pseudo-Casimir force between parallel plates immersed in a chiral nematic liquid crystal. We focus on small-separation limit where the director configuration between the plates inducing strong homeotropic anchoring is uniform. We find that the force is attractive at separations smaller than the crossover distance and repulsive otherwise, and that it diverges log...

The noise and performance limitations of optical sensors that utilize Fabry–Perot interferometry detection are investigated. A Fabry–Perot interferometer consists of two partially transparent parallel plates with reflective inner surfaces. The plates form a cavity with an optical resonance that depends on the distance between them. At resonant wavelengths, the incident light energy is transmitt...

We present the first proper motion study of M10 (NGC 6254). Absolute proper motions of about 532 stars in the field of the globular cluster M10 were determined with respect to Hipparcos and ACT reference stars. In addition to photographic plates of Bonn and Shanghai also wide field CCD observations as second epoch plates were used. The wide field CCD observations show an accuracy comparable to ...

A detailed analysis with experimental verification of optical sensors based on Fabry-Perot interferometers is presented. This type of sensor consists of two partially transparent parallel plates with reflective inner surfaces, forming a cavity with an optical resonance that depends on the distance between the plates. At resonant wavelengths, the incident light energy is transmitted through the ...

BACKGROUND Current surgical approaches to the distal radius include dorsal and palmar plate fixation. While palmar plates have gained widespread popularity, few reports have provided data on long term clinical outcomes in comparison. This paper reports the result of a randomised clinical study comparing dorsal Pi plates and palmar, angle-stable plates for treatment of comminuted, intraarticular...

We conducted a study to evaluate the congruency of fit of current scapular plate designs. Three-dimensional image-processing and -analysis software, and computed tomography scans of 12 cadaveric scapulae were used to generate 3 measurements: mean distance from plate to bone, maximum distance, and percentage of plate surface within 2 mm of bone. These measurements were used to quantify congruenc...
