The aim of this study was to investigate the composting of separated pig manure solids with or without a variety of bulking agents at a low initial C/N ratio (12.5-23.3). Compost stability was investigated using an oxygen uptake rate (OUR) test and compost maturity was investigated using a germination index test. All treatments showed typical patterns of compost temperature. Temperatures above ...

Filamentous bulking and foaming are the most common settling problems experienced in activated sludge (AS) wastewater treatment plants (WWTPs). The quality of final effluent is poor during episodes foaming, which an environmental, human health economic burden. Remedial measures often ineffective, traditional non-specific methods such as chlorination may also negatively impact important function...

1. The breakdown and faecal bulking capacity of dietary fibre preparations from wheat bran, apple, cabbage, carrot, and guar gum were compared in man and rat. 2. The degradation of the fibre showed good correlation between man and rat (r 0.99, regression coefficient 0.86). Wheat bran was the least well-digested, 66 and 59% of the neutral sugars being excreted in faeces of man and rat respective...

Bulk in the distal colon provides protection against a range of large bowel disorders, but a simple standardized measure of the relative bulking efficacy of foods, for use in dietary management of distal colonic bulk, has not been available. This paper describes a faecal bulking index (FBI) for standardized measurement of the relative colonic bulking efficacy of foods relative to a reference ma...

BACKGROUND Urinary and fecal continence can be achieved by constructing catheterizable continent channels that provide access to the bladder and bowel. Some patients develop persistent stomal leakage. A minimally invasive method of injection with a bulking agent for treatment of stomal incontinence was evaluated. METHODS A retrospective review identified patients with incontinence of their ca...

Filamentous cells belonging to the candidate bacterial phylum KSB3 were previously identified as the causative agent of fatal filament overgrowth (bulking) in a high-rate industrial anaerobic wastewater treatment bioreactor. Here, we obtained near complete genomes from two KSB3 populations in the bioreactor, including the dominant bulking filament, using differential coverage binning of metagen...

Stress urinary incontinence is a major problem at the field of female urology and urogynecology. Symptomatically, this is a losing of the urine on physical efforts, coughing or sneezing. Incompetency of the urethral closing mechanisms are causing urine loss. Mid-urethral synthetic slings are the gold standard of the treatment of the stress urinary incontinence. At the same time, different ureth...

To evaluate the efficacy and safety of different bulking agents for treating urinary incontinence in women, a systematic review including only randomized controlled trials was performed. The subjects were women with urinary incontinence. The primary outcomes were clinical and urodynamic parameters. The results were presented as a weighted mean difference for non-continuous variables and as rela...

Changes in physicochemical characteristics, chemical structures and maturity of swine, cattle and chicken manures and composts during 70-day composting without addition of bulking agents were investigated. Physicochemical characteristics were measured by routine analyses and chemical structures by solid-state 13C NMR and FT-IR. Three manures were of distinct properties. Their changes in physico...
