1NATURAL PRODUCTIVITY OF ACRYLIC ACID AND DIMETHYL SULPHIDE DURING A SUMMER BLOOM OF PHAEOCYSTIS POUCHETII IN ANTARCTIC COASTAL WATER显示文摘Water samples were collected over P. pouchelii bloom period beginning in November 1988, in 15m water column, from 10km offshore of Davis Station, Vestfold Hill, Antarctica. The concentrations of acrylic acid and dimethyl sulphide (DMS), which are toxic compounds in the water samples, were determined by HPLC and GC. The result shows that the concentration of acrylic acid varies in 0.001-0.510vmol·L-1 and the concentration of DMS in 0.003-0.588 mol·L-1 during P. pouchetii bloom. Both the increased since late December 1988 and reached the highest concentration in early January 1989, then they decreased rapidly and returned to lower level from middle January to February in agreement with variation in cell number of the unicell alga P. pouchetii. The correlation coefficients between acrylic acid and P. pouchetii and between DMS and P. pouchetii are all 0.998. It is undoubted that P. pouchetii produced acrylic acid and DMS. The highest productivity of acrylic acid and DMS were 9.76×10-8Andrew Davidson Harry Burton 1992Chinese Journal of Polar Science1992,3,1:5
2Anisotropically Shaped Magnetic/Plasmonic Nanocomposites for Information Encryption and Magnetic-Field-Direction Sensing显示文摘Instantaneous control over the orientation of anisotropically shaped plasmonic nanostructures allows for selective excitation of plasmon modes and enables dynamic tuning of the plasmonic properties.Herein we report the synthesis of rod-shaped magnetic/plasmonic core-shell nanocomposite particles and demonstrate the active tuning of their optical property by manipulating their orientation using an external magnetic feld.We further design and construct an IR-photoelectric coupling system,which generates an output voltage depending on the extinction property of the measured nanocomposite sample.We employ the device to demonstrate that the nanocomposite particles can serve as units for information encryption when immobilized in a polymer flm and additionally when dispersed in solution can be employed as a new type of magnetic-feld-direction sensor.Xiaojing Wang Ji Feng Huakang Yu Yue Jin Andrew Davidson Zhiyuan Li Yadong Yin 2018Research2018,,1:4
3Gastroenterology service in a teaching hospital in rural New Zealand, 1991-2003显示文摘AIM: To retrospectively collect inpatient and outpatient data and to assess the use of endoscopic procedures during the years 1991, 1997 and 2003 to analyse for trends. METHODS: This retrospective survey was conducted in a University-associated Gastroenterology Unit offering secondary and tertiary health care services for a population of approximately 182 000 people in Southern New Zealand. Data collected included patient contacts (inand outpatients), gastroscopic and colonoscopic investigations. RESULTS: We observed a significant increase in the absolute numbers of patient contacts over the years (1991: 2308 vs 1997: 2022 vs 2003: 2783, P < 0.0001) with inflammatory bowel disease, other diseases of the colon, anus and rectum and iron studies related disorders decreasing significantly but liver disease and constipation increasing linearly over time. The use of endoscopy services remained relatively stable but colonoscopic investigations for a positive family history of colorectal cancer increased significantly while more gastroscopies were performed for unexplained anaemia. CONCLUSION: The whole spectrum of gastroenterology contacts was studied. A substantial proportion of colonoscopies and outpatient consultations were undertaken to screen for colorectal cancer. This proportion is likely to grow further. Our fi ndings have implications for the recruitment and training of the next generation of gastroenterologists.Michael Schultz Andrew Davidson Sarah Donald Bogna Targonska Angus Turnbull Susan Weggery Vicki Livingstone John D Dockerty 2009World Journal of Gastroenterology2009,15,5:3
4Posterior interosseous nerve localization within the proximal forearm-a patient normalized parameter显示文摘AIM To provide a 'patient-normalized' parameter in the proximal forearm. METHODS Sixty-three cadaveric upper extremities from thirty-five cadavers were studied. A muscle splitting approach was utilized to locate the posterior interosseous nerve(PIN) at the point where it emerges from beneath the supinator. The supinator was carefully incised to expose the midpoint length of the nerve as it passes into the forearm while preserving the associated fascial connections, thereby preserving the relationship of the nerve with the muscle. We measured the transepicondylar distance(TED), PIN distance in the forearm's neutral rotation position, pronation position, supination position, and the nerve width. Two individuals performed measurements using a digital caliper with inter-observer and intraobserver blinding. The results were analyzed with the Wilcoxon-Mann-Whitney test for paired samples. RESULTS In pronation, the PIN was within two confidence intervals of 1.0 TED in 95% of cases(range 0.7-1.3 TED); in neutral, within two confidence intervals of 0.84 TED in 95% of cases(range 0.5-1.1 TED); in supination,within two confidence intervals of 0.72 TED in 95% of cases(range 0.5-0.9 TED). The mean PIN distance from the lateral epicondyle was 100% of TED in a pronated forearm, 84% in neutral, and 72% in supination. Predictive accuracy was highest in supination; in all cases the majority of specimens(90.47%-95.23%) are within 2 cm of the forearm position-specific percentage of TED. When comparing right to left sides for TEDs with the signed Wilcoxon-Mann-Whitney test for paired samples as well as a significance test(with normal distribution), the P-value was 0.0357(significance-0.05) indicating a significant difference between the two sides.CONCLUSION This 'patient normalized' parameter localizes the PIN crossing a line drawn between the lateral epicondyle and the radial styloid. Accurate PIN localization will aid in diagnosis, injections, and surgical approaches.Srinath Kamineni Crystal R Norgren Evan M Davidson Ellora P Kamineni Andrew S Deane 2017World Journal of Orthopedics2017,8,4:2
