OBJECTIVE To examine the effect on hospital presentations for asthma of brief exposures to sulphur dioxide (SO2) (within the range 0-8700 micrograms/m3) emanating from two point sources in a remote rural city of 25,000 people. METHODS A time series analysis of SO2 concentrations and hospital presentations for asthma was undertaken at Mount Isa where SO2 is released into the atmosphere by a co...

This work examines the process of detecting and quantifying volcanic SO2 plumes using the Airborne Hyperspectral Infrared Imager (AHI) developed by the University of Hawaii. AHI was flown over Pu'u'O'o Vent of Kilauea Volcano in Hawaii to collect data on SO2 plumes. AHI is a LWIR pushbroom imager sensitive to the 7.5 11.5 μ region. Spectral analysis and mapping tools were used to identify and c...

SO2emissions, the largest sourceof anthropogenic aerosols, can respond rapidly toeconomic and policy driven changes. However, bottom-up SO2 inventories have inherent limitations owing to 24–48months latency and lack of month-to-month variation in emissions (especially in developing countries). This study develops a new approach that integrates OzoneMonitoring Instrument (OMI) SO2 satellitemeasu...

Abstract The complete convergence results for weighted sums of widely orthant-dependent random variables are obtained. A strong law large numbers is also Our extend and generalize some Chen Sung (J. Inequal. Appl. 2018:121, 2018), Zhang et al. Math. 12:1063–1074, (Stat. Probab. Lett. 154:108544, 2019), Lang (Rev. Mat. Complut., 2020, 10.1007/s13163-020-00369-5 ), Liang 48:317–325, 2000).

Carbon-enriched coal fly ash was evaluated in this work as a low-cost adsorbent for SO2 removal from stack gases. The unburned carbon in coal fly ash was concentrated by mechanical sieving and vegetal oil agglomeration. The carbon concentrates were activated with steam at 900 degrees C in order to develop porosity onto the samples. The performance of these samples in the SO2 abatement was teste...

Abstract This is a rare presentation of an impacted gallstone leading to ileovaginal fistula. A 76-year old female presented with 4 week history faecal vaginal discharge and weight loss on background endometrial cancer treated chemotherapy radiotherapy 9 years ago. She was initially investigated pelvc MRI which showed collection in the stump. further abdominal pelvic CT scan revealed cholecysto...

Although hemoglobin oxygen saturation (sO2) in the microvasculature is an essential physiological parameter of local tissue functions, non-invasive measurement of microvascular sO2 is still challenging. Here, we demonstrated that visible-light optical coherence tomography (vis-OCT) can simultaneously provide three-dimensional anatomical tissue morphology, visualize microvasculature at the capil...
