Abatement of nitrous oxide over natural and iron modified natural zeolites
(ELSEVIER SCIENCE BV, 2011)The natural zeolite obtained from the Sivas-Yavu region in Turkey and iron modified forms were studied for the decomposition of N(2)O and selective catalytic reduction of N(2)O with NH(3). The natural and iron modified ... -
Abdominal blockage of iliohypogastric and ilio-inguinal nerves for management of post-caesarean pain: A novel method
(SA MEDICAL ASSOC HEALTH & MEDICAL PUBL GROUP, 2012)Objective. The aim of this study was to compare pain relief after caesarean section achieved by an intra-abdominal iliohypogastric and ilio-inguinal (IHII) nerve block with levobupivacaine with that in patients given a ... -
Abnormal Heart Rate Recovery in Stable Heart Failure Patients
(WILEY, 2013)Background Heart rate decrease after exercise, that is associated with reactivation of parasympathetic system, is important, as it is also associated with mortality. Previous studies have shown that this is an independent ... -
