Abstract Socially vulnerable populations in the United States are bearing highest costs of water scarcity, which is likely to worsen with climate change, population growth, and growing disparities between areas high demand location available supplies. Prior research showing that socially groups inequitably exposed shortages has focused on singular dimensions social vulnerability, typically rela...
purpose: to estimate the magnitude and causes of visual impairment (vi) in subjects aged ≥ 50 years in varamin district in 2009 using the proposed method by the world health organization (who). method: this cross sectional population based survey was performed in varamin targeting people over the age of 50 years using the proportional probabilities to size and cluster compact segment sampling m...
Abstract Funding Acknowledgements Type of funding sources: None. Background Low-flow conditions are associated with higher mortality after transcatheter aortic valve implantation (TAVI) for severe stenosis (SAS). Two parameters have been described to determine low-flow status – although the most currently used is stroke volume index, transaortic flow rate (FR divided by left ventricle ejection ...
This paper examines the causal relationship between global stock market performance and Google search volume index (SVI) surrounding disastrous event of coronavirus (COVID-19) outbreak. Based on 6,106 index-day observations 71 countries during period from 1 January 2020 to 29 May 2020, we find that both SVI growth in confirmed cases lower returns. Consistent with information discovery theory, w...
Stochastic variational inference (SVI) is emerging as the most promising candidate for scaling inference in Bayesian probabilistic models to large datasets. However, the performance of these methods has been assessed primarily in the context of Bayesian topic models, particularly latent Dirichlet allocation (LDA). Deriving several new algorithms, and using synthetic, image and genomic datasets,...
Each year, residency programs work diligently to identify the best applicants for their respective programs, given the increasing volume of applications. Interview offers are often based on a mix of subjective and objective measures, with different programs relying more or less on each. A holistic application review involves a flexible and individualized way of assessing an applicant's capabili...
In this study, photocatalysis was used to improve the dewaterability and settleability of waste activated sludge (WAS) by a solar photocatalytic reactor with transparent Ag/TiO2 film as photocatalyst. Specific resistance of filtration (SRF) and sludge volume index (SVI) were used to evaluate WAS dewaterability and settleability, respectively, and the mechanism of photocatalysis was interpreted ...
This study investigated the effects of solid retention time (SRT) on sludge characteristics and operational performance in enhanced biological phosphorus removal (EBPR) reactor. The results showed that the reactor operated at SRT of / = 8.3 d could achieve phosphate removal efficiency > 90 % and SVI < 100 mL g–1. In comparison, increasing SRT to / = 16.6 d led to a decrease of phosphate removal...
Ten patients with congestive heart failure (CHF), in III and IV NYHA Class, were treated orally with a single dose of ibopamine ranging from 1.2-3.3 mg/kg, and were studied using the Swan-Ganz catheter and thermodilution technique. Cardiac index (CI) and stroke volume index (SVI) were increased, and mean pulmonary pressure (PAP), systemic vascular resistances (SVR) were lowered. Ibopamine incre...
the activated sludge process is the most used biological wastewater treatment method in the world. sludge bulking is one of the most common problems relateing to activated sludge wastewater treatment, and this fact causes poor settling in secondary sedimentation tank. sludge volume index(svi) and the zone settling velocity(zsv) are parameters to quantify the settleability of activated sludge . ...
