The fluid flow history during diagenesis of the Lower Triassic Bulgo sandstone has been investigated through integrated analyses of petrography, stable isotope and fluid inclusion. Combined application of these techniques was intended to constrain the temperature, timing, chemistry and source of pore fluids during diagenetic cementation events in the Lower Triassic Bulgo sandstone. The diagenesis proceeded in two different flow regimes: early dynamic fluid flow regime and late slow static fluid flow regime. The former was characterized by a slight increase of δ( 18 O) of pore waters form estimated -15×10 -3 to -14×10 -3 with the temperature increasing from ~10 ℃ to ~75 ℃. During early diagenesis, early clays and pore filling carbonates precipitated from the pore waters. The late slow flow/static fluid regime was characterized by a rapid 18 Oenrichment process. δ( 18 O) of pore waters increased from -14×10 -3 to -5×10 -3 with the temperature increasing from 75 ℃ to 110 ℃. During the late diagenesis, kaolin (generation Ⅱ), quartz and illite crystallized. Oil migrated to the sandstones of the Bulgo sandstone during quartz cementation. 展开更多

The directional-spectrum model of internal waves in shallow seas given by Xiao and Fang (1991 )was used to analyze the observation data gathered in April, 1981, in the sea off Sydney,Australia.Some reasonable results were obtained. The energy ratio between Wavemodes 1 and 2 was about 2 for most frequencies and was up to 8 at o = 0.23 cph.Wave components with frequencies 0.1-0.8 cph were generated in the deep sea,and propagated onshore,while those with frequencies higher than 0.8 cph were locally generated by the interaction between longshore currents and bottom topography.Several surveys were carried out in the sea off Sydney, Australia (Cresswell, 1974,Cresswell and Boland, 1981 ,and Fang,Boland and Cresswell, 1984). The survey performed in April 1981 by Fang, Boland and Cresswell (1984) was outstandingly successful. To draw some deterministic and stochastic characters of internal waves, Fang, Boland and Cresswell (1984) and Fang (1987) analyzed these data gathered in 1981 and obtained some 展开更多

Objective: To determine the prevalence of H. pylori induced gastritis and its association with development of chronic inflammation and carcinoma with reference to updated Sydney classification, to ensure the proper diagnosis and timely treatment. Methods: This was a cross sectional study conducted at the Department of Pathology, Dow Diagnostic Reference and Research Laboratory for the year 2018. Analysis of about 726 gastric biopsy specimens was performed to identify the epidemiological status of the disease. On the other hand, 100 of the specimens were analysed according to Sydney classification to ensure the accurate diagnosis of the gastritis and related disorders. Out of 726 biopsy samples positive samples for carcinoma were investigated in detail histological features. Giemsa stain was used to visualize the h pylori bacteria and the sections of biopsies were subjected to haematoxylin and eosin staining for histological analysis. Results: Out of 727 cases, H. pylori was found in 492 (67.8%) patients. About 1.79% (13) cases were identified as adenocarcinoma, 0.27% (2) squamous cell carcinoma and 0.13% (1) as B cell non Hodgkin lymphoma. Results of Sydney classification. The degree of chronic inflammatory activity was 57% mild;38% moderate and 3% severe out of a total of 67% cases in an active phase of Hp gastritis. Hp-associated gastritis was the most common form of chronic gastritis, without intestinal metaplasia and with mild activity. The association of h pylori with mild inflammation and Neutrophilic infiltrates of the lamina propria, pits, or surface epithelium was statistically significant (p value Conclusion: The frequency of H. pylori infection is common in our population but the infection is mild to moderate and its Sydney classification reveals that early diagnosis may prevent the later complication. 展开更多

This essay examines Francis Sydney Muschamp’s depictions of the Penelope myth during the Victorian era.The Penelope myth,a significant narrative in the Victorian era,was popularized by the Pre-Raphaelite painters Thomas Seddon(1821-1856),Dante Gabriel Rossetti(1828-1882),John Roddam Spencer Stanhope(1829-1908),Frederick Sandys(1829-1904),and John William Waterhouse(1849-1917).Their interpretations of this epic poem from Homer’s Odyssey(800 BCE)inspired Muschamp(1851-1929).He often depicted Penelope’s unwavering fidelity and patience as female virtuosity and a cunning perception of family values during her husband Odysseus’s long absence.Historically,Penelope was the Queen of Ithaca and the loyal wife of King Odysseus(Ulysses).During her husband’s 20-year absence while fighting in the Trojan Wars,Penelope was pursued by suitors competing for her affection and insisting that Odysseus was dead.Despite their advances,Penelope refused to believe that she had been widowed or abandoned.She devised various tricks to keep the suitors at bay.For example,she told them she would choose one of them to marry after completing a woven funeral shroud for her father-in-law,Laertes.Every day,she worked diligently on the tapestry,a shroud,while the impatient suitors watched her progress,but she secretly unraveled the day’s work at night when they were asleep.The tapestry became known as Penelope’s Web. 展开更多

This paper addresses how the Sydney Opera House(hereafter‘Opera House’),an UNESCO World Heritage site,has responded to climate change over the past three decades to become a more sustainable heritage site.The implementation of climate actions is critical to conserving and strengthening the Opera House’s cultural heritage significance—the building and its function as a performing arts centre and place for the community.The paper points out that climate action has been,and continues to be,achieved at the Opera House by the organisation’s responsibility for its custodianship by(1)bringing the Opera House team together to tackle climate change through good governance;(2)inspiring positive change in the community through creative programming and engagement;(3)holding the organisation accountable by setting and achieving environmental performance benchmarks;(4)implementing practical mitigation measures that also respect heritage values;and(5)applying a participatory approach to climate risk and adaptation planning.The paper argues that the tangible heritage values of the Opera House(e.g.the building and site)were not adversely affected by the engagement and mitigation actions and that these actions were,in fact,conserved and strengthened the site’s intangible heritage values(e.g.its use).This paper aims to provide an example of sustainable management and climate action by a cultural organisation that serves as the custodian of a heritage site. 展开更多
