A Traumatic Direct Inguinal Hernia from Pelvic Ring Disruption by Kevin L. Chow, Eduardo Smith-Singares, James Doherty

“…The formation of TAWH is typically from a combination of local tangential shearing forces and a sudden rise in intraabdominal pressures damaging the muscle, fascia, and peritoneum while the skin remains intact. In patients without hollow viscous injuries and gross contamination, these hernias can be repaired safely with mesh in the acute setting simultaneously with pelvic reduction.…”

Treatment of petrochemical wastewater with low C/N by IFFAS-ESMBR integrated composite process by ZHAO Xuan, LIU Tao, YANG Meng, QIAO Sen

“…Under the applied voltage of -1.2 V, the average growth rate of transmembrane pressure difference(TMP) of CNT-PVDF composite hollow fiber membrane was only 2.5 kPa/d, and the PN/PS of sludge on the membrane surface decreased gradually, indicating that the degree of irreversible membrane fouling was mild. 16S rRNA high-throughput sequencing showed that a large number of carbon and nitrogen removal functional bacteria, such as Rhodobacterales, Verrucomicrobiales, Anaerolineales and Xanthomonadales, were enriched in suspended sludge, membrane surface sludge and carrier surface sludge, which played a significant role in the degradation of organic matter and ammonia nitrogen in the reactor. …”
