The influence of adding a bulking agent on the bio-stabilization and drying of municipal solid waste (MSW) was investigated. Three treatments were considered: the addition of either cornstalks or wood peat to MSW as a bulking agent before bio-drying and a control treatment that contained no bulking agent. Addition of bulking agents to MSW produced less leachate, higher moisture-removal rates, and consumed less volatile solids. Bulking with cornstalks achieved the highest water-removal rate (0.58-0.65kgkg). The extent of organic degradation was related to temperature integration during bio-drying. Lipids and cellulose were the main components of organic losses in all treatments and adding a bulking agent changed the sequence and extent of degradation of biochemical components. The bio-drying index values were 1.75, 3.18, and 2.64 for MSW alone, MSW with cornstalks, and MSW with wood peat, respectively. Evaporation heat was the main component of heat consumption, accounting for 58.1-60.7% of the total energy consumption.

Antibiotic resistance genes (ARGs) rebounding during composting cooling phase is a critical bottleneck in composting technology that increased ARGs dissemination and application risk of compost products. In this study, mature compost (MR) was used as a substitute for rice husk (RH) to mitigate the rebound of ARGs and mobile genetic elements (MGEs) during the cooling phase of sewage sludge composting, and the relationship among ARGs, MGEs, bacterial community and environmental factors was investigated to explore the key factor influencing ARGs rebound. The results showed that aadD, blaCTX-M02, ermF, ermB, tetX and vanHB significantly increased 4.

Polymerase chain reactions (PCR) are most reliable and precise means for nucleic acid analysis of biological samples. A cold-chain system with temperature at around -20°C is generally necessary for storage and transportation of PCR-related reagents. In order to facilitate ambient temperature storage and transportation, this study prepared Taq DNA polymerase and 5 × HS-Taq Mix (as low as 0.

Introduction And Hypothesis: Polyacrylamide hydrogel (PAHG) is a bulking agent used in treatment of stress urinary incontinence (SUI) in women. Some women experience an improvement or cure in stress urinary incontinence (SUI) symptoms lasting only a few weeks after the injection of the bulking agent. The aim of this study was to use three-dimensional ultrasound (3DUS) to describe the changes in volume, number of deposits and echogenicity of the bulking agent 3 months after PAHG injection.

Urinary incontinence is a common complaint of both general practitioners and specialists. An accurate basic diagnosis with a structured medical history and bladder diary, urine analysis, gynaecological examination including pelvic floor assessment and a full bladder cough test can be supplemented by sonography, cystoscopy and urodynamic testing. This will help to differentiate between the different types of urinary incontinence, such as urge incontinence, stress incontinence and overflow incontinence.

Introduction And Hypothesis: Various treatment options are currently available for the management of stress urinary incontinence (SUI). This study was aimed at determining the effectiveness and safety profile of Bulkamid, and identify predictive factors of clinical success.
Methods: This retrospective study conducted in two French urogynecology university centers between September 2019 and December 2023 included all patients with urinary incontinence who received Bulkamid.
