The comparison of hearing loss among diabetic and non-diabetic patients

Introduction: The prevalence of Diabetes Mellitus is steadily increasing. This is a multi- systemic abnormality, causing side- effects which are mainly irreversible. Hearing loss is one of the common symptoms, and there are many studies, with contradictory results. Aim of this study was to compare the hearing loss among diabetic with non- diabetic patients. Material and Methods: In this study 50 diabetic patients were chosen randomly from those overt diabetic patients referred to the Diabetes clinic in Gorgan hospital northern Iran, 50 other patients who referred to the 5th Azar hospital, with any other ENT complaint were also randomly chosen as control group. The case and control groups were matched. Demographic questionnaires were filled for each subjects in case and control groups, and those with intervening factors were omitted from this study. Data were analyzed using SPSS. Results: In this study 66% and 34% of participants were men and women respectively. The age distribution of the patient were 15-75 years. The hearing loss among diabetic patients and non- diabetic subjects were 16% and 5% respectively, which showed that the diabetic patient has3.2 times more possibility to acquire hearing problem. It was also shown, that there was a direct correlation between increasingage and hearing loss. More women are at risk, of getting hearingloss than men. The hearing loss also has a correlation with the duration of disease onset and the consumption of Glibanclamid. Conclusion The careful periodical assessment of hearing loss, and the application of hearing facilities to improve the qualityof diabetic patients life is recommended due to chronic and irreversible Symptom of the disease

Analytical performance modelling of adaptive wormhole routing in the star interconnection network

The star graph was introduced as an attractive alternative to the well-known hypercube and its properties have been well studied in the past. Most of these studies have focused on topological properties and algorithmic aspects of this network. Although several analytical models have been proposed in the literature for different interconnection networks, none of them have dealt with star graphs. This paper proposes the first analytical model to predict message latency in wormhole-switched star interconnection networks with fully adaptive routing. The analysis focuses on a fully adaptive routing algorithm which has shown to be the most effective for star graphs. The results obtained from simulation experiments confirm that the proposed model exhibits a good accuracy under different operating conditions

On computing joint invariants of vector fields

A constructive version of the Frobenius integrability theorem -- that can be programmed effectively -- is given. This is used in computing invariants of groups of low ranks and recover examples from a recent paper of Boyko, Patera and Popoyvich \cite{BPP}
