Effect of Feed Rate and Solid Retention Time (SRT) on Effluent Quality and Sludge Characteristics in Activated Sludge Systems Using Sequencing Batch Reactors
… two key parameters are the Solid Retention Time (SRT) and the substrate loading rate. The latter is related to the two basic designs in activated sludge bioreactor configurations: the Plug Flow Reactor (PFR) and the Completely Stirred Tank Reactor (CSTR). PFR systems have a high substrate loading …

Outcomes among caregivers of toddlers with ASD concerns following implementation of Screen-Refer-Treat, a novel service delivery model for early ASD detection and intervention
… service delivery model, Screen-Refer-Treat (SRT; Ibañez et al, 2019), was developed and implmemented in 4 Washington State counties to increase use of the M-CHAT-R/F (Robins et al., 2014) at 18-month well-child primary care visits and expedite delivery of ASD early intervention (i.e., …

Development of Thai Speech Audiometry Materials for Measuring Speech Recognition Thresholds
… an individual's speech recognition threshold (SRT). Recorded materials for SRT are available in many languages; however there are no widely published recorded SRT materials available in the Thai language. The goal of this study was to develop relatively psychometrically equivalent SRT materials …

Mesenchymal stem cell rescue for bone formation following stereotactic radiotherapy of osteosarcoma
… metastatic disease. Stereotactic radiotherapy (SRT) delivers high dose per fraction radiation to a defined tumor volume with relative sparing of surrounding normal tissues. It has been successfully used as a non-surgical limb salvage procedure to achieve local tumor control of spontaneous OSA in …

The effect of high solid retention times in activated sludge reactors on operational costs at Mitchells Plain WWTP
… difficulty managing solid retention times (SRT), also referred to as sludge age. To avoid dealing with large quantities of sludge waste, some of these WWTPs operate the AS reactors at extended SRTs, far beyond what is required for sufficient nutrient removal or to produce a stable waste …

Development of Tongan Materials for Determining Speech Recognition Thresholds
Speech recognition threshold (SRT) is an important clinical measure that validates the pure-tone average (PTA), assists in diagnosis and prognosis of hearing and hearing impairment, and helps identify non-organic hearing impairment. Few published, recorded, and standardized materials exist in …

Integrating Spatial Transcriptomics Data for Cross-Species Molecular Region Comparison
… functions. Spatially resolved transcriptomics (SRT) technologies present the ability to measure gene expression of single cells within tissues, enabling the detection of unique spatial molecular patterns in the brain. Several computational methods that rely on cellular neighborhood information …

Effect of Solids Retention Time on Activated Sludge Properties and Effluent Quality
The effect of solids retention time (SRT) or sludge age on activated sludge properties and effluent quality was investigated using laboratory scale reactors. It was found that an increase in SRT resulted in an increase in effluent solution polysaccharide, with the < 3,000 daltons (3K) size fraction …

Investigating human pharmaceutical compounds present in municipal and hospital wastewaters and options for their removal
… long aeration and biomass retention times (HRT,SRT), as evidenced by the occurrence of complete nitrification, were more efficient at removing paracetamol, naproxen, bezafibrate and atenolol, than the non-nitrifying plants with relatively shorter HRT and SRT. HWWTPs that operated under elevated …
