Experimental assessment of energy tower's performance: evaluation of the impacts of solar radiation, humidity, and chimney's height on the overall efficiency.

Solar energy is one of the most feasible options to produce energy in countries where unexploited desert areas or solar radiation are abundant. An energy tower is an effective system for electrical power generation that can perform more efficiently along with solar radiation. As the primary aim of the present study, effects of different environmental parameters on total efficacy of energy tower were investigated.

Toothpick impaction in a sigmoid diverticulum.

A 70-year-old woman presented to our emergency department with recurrent episodes of left lower quadrant pain. She subsequently underwent high anterior resection with working diagnosis of acute diverticulitis, but intraoperatively was found to have perforated sigmoid diverticulum due to toothpick impaction. A high index of suspicion is required for diagnosis of toothpick ingestion.
