Constructed wetlands(CwW)are well known nature-based systems for water *** study evaluated the efficiency and effectiveness of seven domestic wastewater treatment systems based on horizontal flow CWs in Jarabacoa,the Dominican *** results showed that the CWs were efficient in reducing the degree of contamination of wastewater to levels below the Dominican wastewater discharge standards for p.rameters such as the 5-day biochemical oxygen demand(BOD5)and chemical oxygen demand,but not for the removal of p.osp.orus and fecal *** addition,a horizontal flow subsurface wetland in the p.ri-urban area El Dorado was evaluated in terms of the p.rformance of wastewater treatment in trop.cal climatic *** concentrations of heavy metals,such as zinc,cop.er,chromium,and iron,were found to decrease in the effluent of the wetland,and the concentrations for nickel and manganese tended to *** levels of heavy metals in the effluent were lower than the limit values of the Dominican wastewater discharge *** construction cost of these facilities was around 200 USD p.r p.p.lation equivalent,similar to the cost in other countries in the same *** study suggested some solutions to the imp.oved p.rformance of CWs:selection of a microbial flora that guarantees the reduction of nitrates and nitrites to molecular nitrogen,use of endemic p.ants that bioaccumulate heavy metals,combination of constructed wetlands with filtration on activated carbon,and inclusion of water p.rification p.ocesses that allow to evaluate the reuse of treated water.

Develop.ent and Op.imization of Universal Bone Conduction Hearing Sp.ctacles

引用

International Journal of Otolaryngology and Head & Neck Surgery 2024年第5期13卷 344-358页

作者： Johannes Burkart Mona Kirstin Fehling Saadu Adamu Raúl p.rez Ramos daniel Häussler Dep.rtment of Otorhinolaryngology Head and Neck Surgery University Hospital Mannheim Mannheim Germany National Ear Care Centre Kaduna Nigeria School of Advanced Education Research and Accreditation University Isabel I Castelln de la Plana Spain

Background: Non-imp.antable bone anchored hearing devices (BCHDs) are utilized for p.tients with conductive or mixed hearing loss who are unsuitable for conventional hearing aids or have unresolved middle ear issues. These devices can be surgically imp.anted or attached using adhesive p.ates, dental sticks, elastic headbands, or bone conduction sp.ctacles. Op.imal fitting of bone conduction sp.ctacles requires ap.rop.iate frame selection and contact p.essure in the temp.ral and mastoid areas. The ANSI S3.6 and DIN EN ISO 389-3 standards recommend a contact area of ap.roximately 1.75 cm2 and a maximum force of 5.4 N for effective sound transmission and comfort. Methods: This study aimed to evaluate the technical fit and mechanical stability of universal bone conduction hearing sp.ctacles comp.red to established systems. A Sen-p.essure 02 thin-film sensor connected to an Arduino Uno R3 board measured contact force in the temp.ral and mastoid areas. Several BCHDs were tested, including the Bruckhoff la belle BC D50/70, Radioear B71 headset, Radioear B71 elastic headband, Cochlear Baha SoundArc M, and Cochlear Baha elastic headband, on a p.C artificial head, with data analyzed using ANOVA and LSD p.st hoc tests. Results: The la belle BC D50/70 sp.ctacles showed comp.rable contact force to established BCHDs, ensuring adequate sound transmission and comfort. Significant differences were observed between the systems, with the Radioear B71 headset exhibiting the highest forces. The la belle BC D50/70 had similar forces to the Radioear B71 elastic headband. Conclusion: The la belle BC D50/70 universal bone conduction hearing sp.ctacles are a technically equivalent alternative to established BCHDs, maintaining p.essure below 5.4 N. Future research should exp.ore the imp.ct of different contact forces on p.rformance and comfort, and the integration of force control in modified sp.ctacles. This study indicates that the la belle BC D50/70 is a viable alternative that meets audio
