We conducted sentinel-based surveillance for norovirus in the Pudong area of Shanghai, China, during 2012-2013, by analyzing 5,324 community surveys, 408,024 medical records, and 771 laboratory-confirmed norovirus infections among 3,877 diarrhea cases. Our analysis indicated an outpatient incidence of 1.5/100 person-years and a community incidence of 8.9/100 person-years for norovirus-associate...
A series of new dispiro[fluorene-9',6,9'',12-indeno[1,2b]fluorenes] (DSF-IFs) has been synthesised. These new building blocks for blue-light-emitting devices and electroactive polymers combine indenofluorene (IF) and spirobifluorene (SBF) properties. We report here our synthetic investigations towards these new structures and their thermal, structural, photophysical and electrochemical properti...
The state of Oklahoma has experienced an unprecedented increase in earthquake activity since 2009, likely driven by large-scale wastewater injection operations. Statewide injection rates peaked in early 2015 and steadily decreased thereafter, approximately coinciding with collapsing oil prices and regulatory action. If seismic activity is primarily driven by fluid injection, a noticeable seismo...
We review the "critical point" concept for large earthquakes and enlarge it in the framework of so-called "finite-time singularities." The singular behavior associated with accelerated seismic release is shown to result from a positive feedback of the seismic activity on its release rate. The most important mechanisms for such positive feedback are presented. We solve analytically a simple mode...
Robert Anthony Department of Earth and Environmental Science, New Mexico Institute of Mining and Technology Abstract Since the early 1960s when Maruyama and Burridge and Knopoff convincingly demonstrated that the elastodynamic radiation patterns exhibited by shear faulting in an isotropic, elastic medium were consistent with a pair of force couples, it has become standard practice amongst seism...
Superficial transient discoloration of the dorsum of the tongue may be caused by some foods, beverages and drugs (such as iron salts, bismuth, chlorhexidine, lansoprazole, amoxicillin, clarithromycin). When such discoloration noticeably affects the posterior dorsum of the tongue with longer filiform papillae and stained dark brown or black, the term ‘black hairy tongue’ is used. Black tongue (l...
petri disease is responsible for grapevine decline and occurs wherever grapevines (vitis vinifera) are cultivated. phaeoacremonium species are among the principal hyphomycetes associated with petri disease. during 2009, a field survey was conducted throughout different vineyards in the fars province of iran in order to determine the fungal pathogens associated with the vine decline observed in ...
Infection of middle ear and infection of sinuses are prevalent diseases in human populations which are caused by various etiological agents. To determine and compare the frequency of different virulent bacteria and fungi, the following study was conducted. 58 Patients with sinusitis and 52 with otitis media, which were candidates for surgery were studied irrespective of age and gender. Tissue s...
