Computed linewidths of SO2

Self-broadened and foreign-gas (N2 and O2) broadened linewidths of sulfur dioxide, for both type A and type B bands, have been calculated using the Anderson-Tsao-Curnutte theory of line broadening. Computed values of these linewidths at 300 K are given for all the transitions with J or = 20 and K sub minus 1 or = 15. Air-broadened linewidths have also been calculated for SO2 at 250 K and 200 K for these transitions

Nu sub 1 plus nu sub 3 combination band of SO2

The infrared-active vibration-rotation combination band nu sub 1 + nu sub 3 of sulfur dioxide was measured with moderately high spectral resolution. Quantum number identifications of spectral lines were made by comparison with theoretically computed spectra which include the effects of centrifugal distortion. Relative line intensities were also calculated. The band center for nu sub 1 + nu sub 3 was determined to be 2499.60 + or - 0.10/cm

Fundamental bands of S(32)O2(16)

The infrared-active vibration-rotation fundamentals of sulfur dioxide were measured with moderately high spectral resolution. Quantum number assignments were made for spectral lines from J = O to 57, by comparison with theoretically computed spectra which include the effects of centrifugal distortion. The following values for the band centers were determined: nu sub 1 = 1151.65 + or - 0.10/cm, nu sub 2 = 517.75 + or - 0.10/cm, and nu sub 3 = 1362.00 + or - 0.10/cm. Intensities of the observed lines have also been computed. Dipole moment derivatives were obtained

Management of Morel-Lavallee lesion of the knee: Twenty-seven cases in the National Football League

BACKGROUND: The Morel-Lavallee lesion is a closed degloving injury most commonly described in the region of the hip joint after blunt trauma. It also occurs in the knee as a result of shearing trauma during football and is a distinct lesion from prepatellar bursitis and quadriceps contusion. PURPOSE: To review the authors\u27 experience with Morel-Lavallee lesion of the knee in the elite contact athlete to construct a diagnostic and treatment algorithm. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Twenty-seven knees in 24 players were identified from 1 National Football League team\u27s annual injury database as having sustained a Morel-Lavallee lesion between 1993 and 2006. Their charts were retrospectively reviewed. RESULTS: The most common mechanism of injury was a shearing blow on the playing surface (81%). The most common motion deficit was active flexion (41%). The mean time for resolution of the fluid collection and achievement of full active flexion was 16.3 days. The mean number of practices missed was 1.5. The mean number of games missed was 0.1. Fourteen knees (52%) were treated successfully with compression wrap, cryotherapy, and motion exercises. Thirteen knees (48%) were treated with at least 1 aspiration, and 6 knees (22%) were treated with multiple aspirations for recurrent serosanguineous fluid collections. In 3 cases (11%), the Morel-Lavallee lesion was successfully treated with doxycycline sclerodesis after 3 aspirations failed to resolve the recurrent fluid collections; return to play was immediate thereafter in each case. CONCLUSION: In football, Morel-Lavallee lesion of the knee usually occurs from a shearing blow from the playing field. Diagnosis is confirmed when examination reveals a large suprapatellar area of palpable fluctuance. Elite athletes are typically able to return to practice and game play long before complete resolution of the lesion. Recurrent fluid collections can occur, necessitating aspiration in approximately half the cases for successful treatment. Recalcitrant fluid collections can be safely and expeditiously treated with doxycycline sclerodesis

Current scenario and challenges for bone retrieval for allograft use in North India

Bone grafts are the second most common tissue transplanted. With advances in the treatment of musculoskeletal tumors, limb salvage surgery, with its concomitant demand for bone graft, has increased significantly. This study aims to evaluate current scenario for bone donation in north India. This study was done in bone bank, Government Medical College, Kota, Rajasthan. Inclusion and exclusion criteria of bone donors were followed as per the APASTB standards of tissue banking. Bone was retrieved from deceased donor and live donors after proper consent and counselling in this institute during period 01 January 2021 to 31 January 2022. During the period of study bones were retrieved from 26 donors – 24 live donors and 2 cadavers. Out of 24 live donors 20 were femoral head, 2 tibia and fibula and 2 hemi-radius and hemi-ulna. All donors were between 28-71-year age group and mean age was 56 years. 18 males and 8 females participated in study. There is huge difference between demand and supply of bone allograft in this region of country. There is lack of initiative from government for encouraging people to donate bone along with other organ and tissue donations. Lack of infrastructure for to and fro transport of bone retrieval from deceased and live donors to storage unit results in loss of bone samples. Less trained personnel and sufficiently low coordination between various institutes. Concerns of family members and misconceptions to be addressed properly to reduce morbidity burden in society

Universal Ratios in the 2-D Tricritical Ising Model

We consider the universality class of the two-dimensional Tricritical Ising Model. The scaling form of the free-energy naturally leads to the definition of universal ratios of critical amplitudes which may have experimental relevance. We compute these universal ratios by a combined use of results coming from Perturbed Conformal Field Theory, Integrable Quantum Field Theory and numerical methods.Comment: 4 pages, LATEX fil

Biomechanical evaluation of fixation of comminuted olecranon fractures: one-third tubular versus locking compression plating

New concepts in plate fixation have led to an evolution in plate design for olecranon fractures. The purpose of this study was to compare the stiffness and strength of locking compression plate (LCP) fixation to one-third tubular plate fixation in a cadaveric comminuted olecranon fracture model with a standardised osteotomy. Five matched pairs of cadaveric elbows were randomly assigned for fixation by either a contoured LCP combined with an intramedullary screw and unicortical locking screws or a one-third tubular plate combined with bicortical screws. Construct stiffness was measured by subjecting the specimens to cyclic loading while measuring gapping at the osteotomy site. Construct strength was measured by subjecting specimens to ramp load until failure. There was no significant difference in fixation stiffness and strength between the two fixation methods. All failures consisted of failure of the bone and not of the hardware. Contoured LCP and intramedullary screw fixation can be used as an alternative treatment method for comminuted olecranon fractures as its stiffness and strength were not significantly different from a conventional plating techniqu
