Evaluation of Water Retention Capacity of Bulkheads in Underground Coal Mines by Yuan Hang, Lichuang Jin, Binbin Yang, Ning Li, Shichong Yuan, Zhilin Gao, Linxuan Sun, Sen Zheng, Mingming Hu

“…The mechanism of water flow in and around the bulkheads and the surrounding rock is studied for Panel No. 21102 in the Sanhejian coal mine in Xuzhou, China. Based on an analysis of the properties of the bulkheads and the surrounding rock, three types of water conducting pathways are identified: (1) a water conducting pathway at the interface between the bulkhead and the surrounding rock; (2) a water conducting pathway in the faults of the rock; and (3) a water conducting pathway in the fractures of the rock. …”

Antibiotic-Resistant Escherichia coli in Women with Acute Cystitis in Canada by Warren J McIsaac, Rahim Moineddin, Christopher Meaney, Tony Mazzulli

“…BACKGROUND: Trimethoprim-sulfamethoxazole (TMP-SMX) has been a traditional first-line antibiotic treatment for acute cystitis; however, guidelines do not recommend TMP-SMX in regions where Escherichia coli resistance exceeds 20%. While resistance is increasing, there are no recent Canadian estimates from a primary care setting to guide prescribing decisions.…”
