Emission models are widely applied tools for estimating atmospheric emissions from wastewater treatment plants (WWTPs). The friction velocity u∗ is a key variable for the modelling of emissions from passive liquid surfaces in WWTPs. This work evaluated different parametrisations of u∗ for passive liquid surfaces at the scale of WWTP units, which present relatively small fetches, based on available wind friction and wave data measured at wind-wave tanks (fetches spanning from approximately 3 to 100 m, and wind speeds from 2 to 17 m s(-1))...

Globular proteins, such as cytochrome c (cyt c), display an organized native conformation, maintained by a hydrogen bond interaction network. In the present work, the structural interrogation of kinetically trapped intermediates of cyt c was performed by correlating the ion-neutral collision cross section (CCS) and charge state with the starting solution conditions and time after desolvation using collision induced activation (CIA), time resolved hydrogen/deuterium back exchange (HDX) and trapped ion mobility spectrometry - mass spectrometry (TIMS-MS)...

Sickle cell disease (SCD) is a common cause of cerebrovascular disease in childhood. Primary stroke prevention is effective using transcranial Doppler (TCD) scans to measure intracranial blood velocities, and regular blood transfusions or hydroxycarbamide when these are abnormal. Inadequate TCD scans occur when it is not possible to measure velocities in all the main arteries. We have investigated the prevalence and significance of this in a retrospective audit of 3915 TCD scans in 1191 children, performed between 2008 and 2015...

BACKGROUND: Given the safety concerns regarding pharmacological agents, and the considerable impact of headache and migraine on the sufferer's quality of life, many people seek other treatment options beyond conventional medication and care to address their symptoms; this includes complementary and alternative medicine (CAM). Some CAM interventions have shown promising results in clinical trials of headache and migraine management. Nonetheless, there has been little research exploring the reasons for using CAM, and the types of CAM used, among this population...

New nanoscale zero-valent iron/carbon (nZVI/C) composites were successfully synthesized by heating natural hematite and pine sawdust at 800 ºC under nitrogen conditions. The characteristic results indicated that as-prepared nZVI/C composites presented the massive reactive sites by SEM, XRD, FT-IR and XPS techniques. No effect of ionic strength revealed that inner-sphere surface complexation dominated uptake of U(VI) on nZVI/C composites. The uptake mechanism of U(VI) on nZVI/C composites was demonstrated to be the simultaneous adsorption and reduction by XPS and XANES techniques...

We employed the diffusion Monte Carlo method, under fixed node approximation, to investigate the various ground state properties of a mass-asymmetric electron-hole bilayer system. Particularly, we calculated the ground state energy, the condensation fraction c, and the pair correlation function g(r) at density rs = 5 a.u. for the inter-planer distance d ≤ 0.5 a.u. Based on the characteristics of condensate faction and pair correlation functions, we found the phase transition from the excitonic fluid phase to the biexcitonic fluid phase at d = 0...

BACKGROUND: Approximately 250,000 new cases of breast cancer are diagnosed yearly in the U.S. resulting in more postmastectomy breast reconstructions (PMBRs). The acellular dermal matrix (ADM) expander-implant method became popular in the mid-2000s, but newer techniques such as the inferior deepithelialized flap (IDF) has more recently been described. We hypothesize that ADMs and IDFs provide comparable aesthetic outcomes, with no difference in complication rates and operative characteristics...

The chemical and structural changes of three lignocellulosic biomass samples during pyrolysis were investigated using both conventional and advanced characterization techniques. The use of ATR-FTIR as a characterization tool is extended by the proposal of a method to determine aromaticity, the calculation of both CH2/CH3 ratio and the degree of aromatic ring condensation ((R/C)u). With increasing temperature, the H/C and O/C ratios, XA and CH2/CH3 ratio decreased, while (R/C)u and aromaticity increased. The micropore network developed with increasing temperature, until the coalescence of pores at 1100°C, which can be linked to increasing carbon densification, extent of aromatization and/or graphitization of the biomass chars...

Congenital thrombotic thrombocytopenia purpura (cTTP) is a very rare disorder worldwide. Standard treatment of recognized cases has been to administer fresh frozen plasma as the source of ADAMTS13, to replenish the absent ADAMTS13 enzyme. An alternative source, a plasma-derived factor VIII concentrate used for hemophilia A, and found to contain this enzyme, was reported to be effective in 1 patient in the United States. We now report details on a US cohort of 8 cTTP patients who have been successfully treated for varying periods with a marketed antihemophilic factor concentrate Koate-DVI...
