Prospective study of Functional Outcome of Fracture of Periglenoid of Scapula Treated with Open Reduction and Internal Fixation

BACKGROUND: Displaced glenoid neck fractures and glenoid neck fractures associated with clavicle fracture (floating shoulder), acromio-clavicular joint disruption, coracoids and acromion fractures leads to glenohumeral join instability. This study shows how early surgical intervention of these fractures with open reduction and internal fixation, followed by early mobilisation and rehabilitation improves functional outcome in patients with periglenoid fractures. AIMS AND OBJECTIVES: To assess the functional outcome after treatment of periglenoid fractures of scapula with open reduction and internal fixation. MATERIAL AND METHODS: We prospectively studied 10 patients with periglenoid fractures, among them 8 were male and 2 were female. Functonal outcome following surgical intervention was assessed using the Constant-Murley score. RESULTS: Functional outcome was measured using Constant-Murley score. In our study 3 patients had excellent functional outcome following surgery, 4 patients had good functional outcome, 2 patients had moderate functional outcome and 1 pateint had poor functional outcome. This study shows earlier surgical intervention and early mobilization improves ROM of shoulder joint. CONCLUSION: This study concludes that periglenoid fractures with specific indications when treated with RECON plating, followed by early mobilisation and rehabilitation definetly improves functional outcome of glenohumeral joint

Spectral fluctuation characterization of random matrix ensembles through wavelets

A recently developed wavelet based approach is employed to characterize the scaling behavior of spectral fluctuations of random matrix ensembles, as well as complex atomic systems. Our study clearly reveals anti-persistent behavior and supports the Fourier power spectral analysis. It also finds evidence for multi-fractal nature in the atomic spectra. The multi-resolution and localization nature of the discrete wavelets ideally characterizes the fluctuations in these time series, some of which are not stationary.Comment: 7 pages, 2 eps figure

Statistical Properties of Fluctuations: A Method to Check Market Behavior

We analyze the Bombay stock exchange (BSE) price index over the period of last 12 years. Keeping in mind the large fluctuations in last few years, we carefully find out the transient, non-statistical and locally structured variations. For that purpose, we make use of Daubechies wavelet and characterize the fractal behavior of the returns using a recently developed wavelet based fluctuation analysis method. the returns show a fat-tail distribution as also weak non-statistical behavior. We have also carried out continuous wavelet as well as Fourier power spectral analysis to characterize the periodic nature and correlation properties of the time series.Comment: 9 pages, 6 figures, Econophys-IV, Kolkata, 200

Stock assessment of seerfishes in the Indian seas

The annual average catch of seerfishes from the Indian seas was 45,0601 during 1995-'99, which constituted 1.8% of the total marine fish catch in India. State-wise Gujarat (28.5%) was the major producer followed by Tamilnadu (15.8%), Maharashtra (15.4%), Andhra Pradesh (11.4%) and Kerala (10.5%). Gill net is the dominant gear in exploiting seerfish followed by trawl, hooks & line, boat seines, shore seines and purse seines. Among the five species, the kingseer Scomberomorus commerson (59.0%) and the spotted seer S. guttatus (35.1%) sustained the fishery, while the streaked seer S.lineolatus and the wahoo Acanthocybium solandri formed only a negligible portion of the fisher

Status of exploitation of seerfishes in the Indian seas

Seerfish production from the Indian seas during the past five decades from 1950s to 1990s, showed an increasing trend. The annual catch increased from 4,505 t in 1953 to 54,8761 in 1998. The average annual catch during the five decadal periods k-aried from 7,278 t in 1950-'59 to 41,575 t in 1990-'99 contributing 1.5% and 1.75% respectively to the total marine fish catch of India. However, the rate of increase through the successive decades decreased indicating the attainment of op- ;imum level of production currently. During 1950-'59, the east coast contributed more (60%) than the west coast (40%), which changed to 36:64 during 1990-'99. iVmong the maritime states of India, Gujarat (25.88%), Maharashtra (16.09%), familnadu (13.59%), Kerala (13.07%) and Andhra Pradesh (12.68%) were the prime seerfish producers during 1990-'99. Gill net (64.8%) was the dominant gear, folowed by trawl (17.4%) and hooks and line (4%) with an average catch rate of 8.1 <g/unit, 0.24 kg/hr and 3.7 kg/unit respectively during 1995-'99. Among the five species, the fishery was sustained only by two species viz., the king seer Scomberomorus commerson and the spotted seer S.guttatus

Collinear cluster tripartition as sequential binary fission in the 235^{235}U(nth_{\rm th},f) reaction

The mechanism leading to the formation of the observed products of the collinear cluster tripartition is carried out within the framework of the model based on the dinuclear system concept. The yield of fission products is calculated using the statistical model based on the driving potentials for the fissionable system. The minima of potential energy of the decaying system correspond to the charge numbers of the products which are produced with large probabilities in the sequential fission (partial case of the collinear cluster tripartition) of the compound nucleus. The realization of this mechanism supposes the asymmetric fission channel as the first stage of sequential mechanism. It is shown that only the use of the driving potential calculated by the binding energies with the shell correction allows us to explain the yield of the true ternary fission products. The theoretical model is applied to research collinear cluster tripartition in the reaction $^{235}$U(n$_{\rm th}$,f). Calculations showed that in the first stage of this fission reaction, the isotopes $^{82}$Ge and $^{154}$Nd are formed with relatively large probabilities and in the second stage of sequential fission of the isotope Nd mainly Ni and Ge are formed. This is in agreement with the yield of the isotope $^{68}$Ni which is observed as the product of the collinear cluster tripartition in the experiment.Comment: 20 pages, 9 figure
