It usually presents with vaginal bleeding, lower abdominal pain and a protruding mass, and requires immediate assessment and surgical management to salvage the prolapsed bowel. Any delay in the treatment may result in bowel ischaemia and perforation which is(More)
A 68-year-old man with expressive dysphasia presented with upper gastrointestinal haemorrhage, jaundice and abdominal pain. He was unable to tolerate ultrasound tranducer pressure. His oesophagogastroduodenoscopy (OGD) showed large blood clots in the stomach with blood trickling from the ampulla. An urgent CT angiogram demonstrated a 32 mm pseudoaneurysm(More)
Following the worldwide success of GSM/EDGE, the 3GPP is in the process of standardizing EDGE Evolution that will be a step further in improving performance, efficiency and other capabilities. Evolved EDGE delivers data rates comparable to 3G networks, using the same GSM spectrum. With EDGE Evolution service performance can be improved, thus enabling more(More)
Objectives: To evaluate learning characteristics of MDI use amongst junior doctors and retention of the skills over few months’ time. Methods: Fifty residents during their first rotation in medicine department were evaluated for baseline performance of 13 individual steps of MDI use. They were evaluated after group demonstration and further individualized(More)
In this paper, we propose a new simple relaying strategy based on bit-interleaved convolutionally coded starquadrature amplitude modulation (QAM) along with coherent/ noncoherent detection. Exploiting this property, a hard limiter is used to enhance power amplifier (PA) efficiency at the relay. Here we are using the higher order modulation for improving(More)
