Early diagnosis and prompt treatment of gastrooesophageal reflux (GOR) can halt unnecessary investigations and prevent medical complications, such as failure to thrive,1 severe oesophagitis,2 and aspiration syndromes.3 The standard investigation for GOR is the upper gastrointestinal barium contrast series. However, because of poor sensitivity and specificity the role of this test in clinical pr...
Opportunistic routing (OR) takes advantages of the spatial diversity and broadcast nature of wireless networks to combat the time-varying links by involving multiple neighboring nodes (forwarding candidates) for each packet relay. This dissertation studies the properties, energy efficiency, capacity, throughput, protocol design and security issues about OR in multihop wireless networks. Firstly...
Gastro-oesophageal reflux (GOR) and bronchoaspiration of gastric content are risk factors linked with ventilator-associated pneumonia. This study was aimed at evaluating the effect of a nasogastric tube (NGT) incorporating a low-pressure oesophageal balloon on GOR and bronchoaspiration in patients receiving mechanical ventilation. Fourteen patients were studied in a semi-recumbent position for ...
We present multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) based broadband power line communication (BPLC) using antenna and fading diversity. We evaluate the proposed MIMO-OFDM system over multi-conductor power line channels, with or without cross-talk between the antenna paths. The proposed scheme employs maximum ratio combining (MRC) that effectively com...
Autosomal dominant hereditary sensory neuropathy (HSN I) is a clinically and genetically heterogeneous group of disorders, and in some families it is due to mutations in the serine palmitoyltransferase (SPTLC1) gene. We have characterized two families with HSN I associated with cough and gastro-oesophageal reflux (GOR). From a large Australian family, 27 individuals and from a smaller family, 1...
two experiments were conducted to determine lysine (lys) requirements of two commercial strains, ross 308 and cobb 500, from 15 to 28d of age. basal diet was formulated to be adequate in all nutrients except for lys. incremental levels of supplemental lys were added to the basal diet generating six experimental treatments in a range from 0.60 to 1.20% digestible lys. birds were randomized acros...

OxyR regulates the expression of the majority of H(2)O(2) responses in Gram-negative organisms. In a previous study we reported the OxyR-dependent derepression of catalase expression in the human pathogen Neisseria gonorrhoeae. In the present study we used microarray expression profiling of N. gonorrhoeae wild-type strain 1291 and an oxyR mutant strain to define the OxyR regulon. In addition to...
In this paper, considering optical feedback as an optical injection, and taking in to account round-trip time role in the external cavity, a standard small signal analysis is applied on laser rate equations. By considering the relaxation oscillation (f2) and external cavity frequencies (f) ratio for semiconductor laser, field amplitude response gain, optical phase and carrier number for long ex...
