Biofibres from biofuel industrial byproduct- seed hull.

Background: Biodiesel production using seeds results in large amount of unused seed hull. These seed hulls serve as a potential source for cellulose fibres which can be exploited as reinforcement in composites.

Methods: These seed hulls were processed using chlorination and alkaline extraction process in order to isolate cellulose fibres.

Anaesthetic management of two different cases of mediastinal mass.

We report the management of two paediatric cases undergoing median sternotomy and right lateral thoracotomy for mediastinal mass. An 8-year-old boy presented with a history of intermittent fever and episodes of respiratory illness since 3 years and a 16-year-old girl presented with dyspnoea, cough, fever and dysphagia for solid foods. Radiological investigation confirmed the diagnoses.
