Industrial waste with silica components is anticipated as an alternative resource for silica stone, which is the main material for Autoclaved Lightweight Concrete (ALC) Panels. Using cements and silica stone powder as main raw materials, ALC panels can be produced to have heat resistance and long-term stability because of their tobermorite crystalline contents. Tobermorite generation requires hydrothermal synthesis under saturated steam pressure at 180 ℃. This study assessed glass waste availability as an alternative resource for silica stone. Candidates were tiles and pot shard waste, liquid crystal glass, and glass bottles. Considering the influence on hydration products, these were evaluated using X-ray powder diffraction (XRD) analysis. Results show that the optimum replacement of silica stone powder with tiles and pot shards waste was approximately 25 % to produce tobermorite formation and dense structure. Calculating the demand of alternative resources and the supply of tiles and pot shard waste, results suggest that the 80 % of its annual emissions are useful.
Objectives: Post-operative urinary incontinence (PUI) after robotic-assisted radical prostatectomy (RARP) is an important complication; PUI occurs immediately after postoperative urethral catheter removal, and, although approximately 90% of patients improve within one year after surgery, it can significantly worsen their quality of life. However, information is lacking on its nature in community hospital settings, particularly in Asian countries. The purposes of this study were to investigate the time required to recover from PUI after RARP and to identify its associated factors in a Japanese community hospital. Methods: Data were extracted from the medical records of 214 men with prostate cancer who underwent RARP from 2019 to 2021. We then calculated the number of days elapsed from the surgery to the initial outpatient visit confirming PUI recovery among the patients. We estimated the PUI recovery rate using the Kaplan–Meier product limit method and evaluated associated factors using the multivariable Cox proportional hazards model. Results: The PUI recovery rates were 5.7%, 23.4%, 64.6%, and 93.3% at 30, 90, 180, and 365 days following RARP, respectively. After an adjustment, those with preoperative urinary incontinence experienced significantly slower PUI recovery than their counterparts, while those with bilateral nerve sparing experienced recovery significantly sooner than those with no nerve sparing. Conclusion: Most PUI improved within one year, but a proportion of those experiencing recovery before 90 days was smaller than previously reported.
