Acute subdural hemorrhage while traveling by bus: A risk factor in the elderly?

A 71-year-old man was delivered to our emergency department by an intercity bus. About 4 hours into a journey, he had complained of a headache to his wife. After one more hour, she noted a change in his level of alertness and notified the bus driver. A computed tomography scan of the head showed a subdural hemorrhage

Gasification of biomass and treatment sludge in a fixed bed gasifier

This study aims to compare synthetic gas (syngas) production efficiencies of a specific forest residue (chamaecyparis lawsoniana) and treatment sludge from a textile industry. The experiments were carried out in a lab-scale fixed bed steel reactor with cyclone separator. Gasification process was assisted by pre-pyrolysis of the samples at 300 degrees C in an inert media via N-2 gas. Internal temperature of the reactor during gasification was 750 degrees C. Dried air was used as an oxidizing agent with the varying flow rates of 0.05, 0.1 and 0.2 L min(-1) in order to determine optimum flow rate. The highest syngas calorific values was calculated around 2500-2677 kcal m(-3) for chamaecyparis and 2500-2680 kcal m(-3) for the treatment sludge when the flow rate was 0.05 L min(-1). Solid residues and liquid products were weighed after each experiment. 55 wt% of chamaecyparis and 30 wt% of treatment sludge were converted in to medium calorific syngas.

EFFICIENCY OF MSW COMPOST FOR REDUCING UPTAKE OF HEAVY METALS BY PLANT

Municipal solid waste (MSW) compost supplied from the Istanbul Solid Waste Recycling and Composting Facility was used to amend soil samples collected within the boundaries of Istanbul. Cat grass (Dactylis glomerata cat grass) seeds were sown in the prepared samples. Plant development was observed for 90 days. pH, Cd, Cu and Ni concentrations in plant samples were measured at the end of every month. Concentrations of forms of Cd, Cu and Ni forms in soil were determined at the beginning and at the end of 90 day period (with sequential extraction). The effect of MSW compost on the transfer of Cd, Cu and Ni from the soil to the plants and the change in the forms of heavy metals in soil was determined. Results of sequential extraction showed that, adding compost into the soil changed the forms of these metals in soil. Plant uptake of Cd decreased, however, those of Ni and Cu increased. Cu concentration in plants that grew in soil with 3 wt. % of compost added reached 136.4 mu g/kg
