Abstract

As it stands now, in the pharmaco-therapy of cerebral resuscitation, short acting barbiturates (thiopentone, pentobarbitone) are the only two drugs which seem to have some selective clinical applicability. In the management of severe head injury patients (Glasgow coma score < 7) there is ample clinical evidence to suggest that barbiturate therapy may be of help in controlling the ICP, in a select group of patients ("uncontrolled ICP") 14. The suggested dose schedule for pentobarbitione therapy would be 5-10 mg/kg bolus followed by 1-3mg/kg/hour infusion. The desired level of plasma barbiturate would be 2-4mg%. The various criteria which would guide in titrating the therapy are-desired end point of therapy (control of ICP, control of convulsions), plasma barbiturate level, EEG burst suppression etc. Continuous monitoring of cardio-vascular parameters like mean arterial pressure, cardiac-index, pulmonary artery wedge pressure etc is very essential. Attention is drawn to the response of a patient to barbiturate therapy and its relation to response to change in PaCO₂.

Abstract

An automatic restoration system targeting on dirt and blotches in images has crucial challenges in the aspect of achieving accuracy in Defect Detection and Removal process. Algorithms developed till date suffer from many false alarms and need two stage false alarm elimination process and also limit the expressiveness of the images and only crudely capture the statistics of natural images. The proposed system poses remedies for problems associated with the existing systems. In general, an automatic restoration system contains two stages named as detection of defects and removal of degraded pixels. Adaptive histogram shape based thresholding algorithm is used for creating defect map for finding the degraded pixel which ensures that there will be no false alarm generation. Next, the quality of degraded pixels will be enhanced by using Field of Experts method. This process preserves the expressiveness of the original images and exactly captures the statistics of natural images. The performance will be measured by computing the quality measures such as PSNR and MSE. Finally, experiment results show that the proposed algorithm guarantees the accuracy and efficiency of defect detection and removal processing.

Abstract

Crude fibre is the fraction of a plant food remaining after the food had been boiled sequentially, first in acid and then in alkali. This measurement was introduced in the first half of the 19th century for veterinary and not human purposes and measured only part of the cellulose and part of the lignin. In 1975, Trowell introduced the term 'dietary fibre' to describe that part of plant food that traverses the small intestine and is not digested by the endogenous secretions within it.
