The taxonomic relationship between two microcyclic rust species, Puccinia melampodii and Puccinia xanthii, recorded from a number of Asteraceae hosts, was explored by comparing teliospore morphology, host specificity and sequence data. Teliospore morphology varied between and within individual rust accessions but, in general, teliospores of P. xanthii were(More)
Ultrasonography has received increasing attention in regional anesthesia in recent years because it allows visualization of the nerves, the needle, and the surrounding structures and makes it possible to monitor distribution of the local anesthetic. Ultrasound technology is unfamiliar to most anesthesiologists, unless they work with transesophageal(More)
In this report we present the case of a patient with ventricular-arterial discordance in which a QAV was diagnosed by bidimensional echocardiogram with the purpose of expanding the anatomical spectrum of the anomalies associated with d-TGA and to manifest the clinical awareness of the consequence that the QAV has on the evolution of the patients that(More)
In vehicular networks, the packet losses in the path between source and destination occur due to packet collisions, fast movement and a limited communication range of vehicles. Reliability mechanisms at different layers are used to mitigate the impact of this issue. In this work, we explain how the loss of ACK frames at MAC layer in conjunction with the(More)
