Dislocation of the index, middle, and ring carpometacarpal joints is an extremely rare injury pattern, with a paucity of published cases. We reviewed the literature and analyzed our own experience to familiarize clinicians with this rare condition through discussion of its clinical presentation, diagnostic considerations, and management. We present the rare case of volar-radial dislocation of t...

We derive conservation and balance laws for the translational gauge theory of dislocations by applying Noether’s theorem. We present an improved translational gauge theory of dislocations including the dislocation density tensor and the dislocation current tensor. The invariance of the variational principle under the continuous group of transformations is studied. Through Lie’s-infinitesimal in...

BACKGROUND The glenohumeral joint becomes dislocated more than any other major joint because it maintains a wide range of motion and its stability is inherently weak. The most common complication following acute initial shoulder dislocation is recurrent dislocation or chronic instability. Imbalance of strength and range of motion in individuals with anterior dislocation can be a contributing fa...

INTRODUCTION Permanent dislocation of the patella (PDP) is a rare condition. In cases of PDP with tibiofemoral arthritis, total knee arthroplasty may be performed through a medial parapatellar approach with patellar realignment. In this article we present two cases of PDP with tibiofemoral osteoarthritis successfully treated via lateral approach TKA without any additional realignment procedure....

The general ring laser operation model is adopted for the large gyroscopes C-II and G. An extended set of auxiliary sensors information is used for the long time period data modeling and ring laser behavior analysis with respect to the ideal case. Both instrumental errors and orientational effects are estimated and compensated where possible. The instrumental stability improved approximately fo...

Improved parameters for the description of Rayleigh scattering in air and for the detailed rotational Raman scattering component for scattering by O(2) and N(2) are presented for the wavelength range 200-1000 nm. These parameters enable more accurate calculations to be made of bulk molecular scattering and of the Ring effect for a variety of atmospheric radiative transfer and constituent retrie...

The rotational transitions of 3,4-dihydro-l,2-pyran in the ground state and six vibrationally excited states have been assigned. The rotational constants for the ground state (A = 5198.1847(24), B = 4747.8716(24) and C = 2710.9161(24) have been derived by fitting fia, ßh and /<c-type transitions. The dipole moment was determined from Stark displacement measurements to be 1.400(8) D with its pri...
