The carbon rod of used zinc-carbon battery was investigated in this research to be recycled as biogas desulfurizer. The carbon rod was taken out from the used battery and crushed to become a pellet with about 1 cm long. To increase its performance, the carbon rod was put in solution of KMnO and water then tested its performance as desulfurizer. it is found that the performance of desulfurizer increase by putting about 200 gram of carbon rod in the solution of KMnO with minimum concentration of 20 gram KMnO/liter water. it is suggested during application to use low flow rate of biogas(around 1-3 liters/minute) to achieve maximum performance.

Hernia mesh prevent dislocation after wide excision and reconstruction of giant cell tumor distal radius

引用

World Journal of Orthopedics 2017年第9期8卷 741-746页

作者： i gede E Wiratnaya i Gusti Bagus Arie M Budiartha i Gusti Ngurah Y Setiawan Dwijo A Sindhughosa i Ketut S Kawiyana putu Astawa Department of Orthopedic and Traumatologic Faculty of Medicine Udayana University Sanglah General Hospital Faculty of Medicine Udayana University Sanglah General Hospital

Giant cell tumor(GCT) remains as major health problem. GCT which located at the lower end of the radius tends to be more aggressive. Wide excision and reconstruction of the wrist in stage 3 of distal radius GCT lesion is an optimal modality to prevent tumor recurrence. However, dislocation often occurs as its complication. We are reporting patient with GCT of distal radius treated with wide excision and reconstruction using nonvascularized fibular graft and the addition of hernia mesh. Circumferential non-absorbable polypropylene hernia mesh was applied, covered radioulnar joint and volar aspect of radius, and served as additional support to prevent dislocation. During five years and two months of follow-up, we found no dislocation in our patient. Furthermore, good functional outcome was obtained. Our finding suggests that the addition of hernia mesh after wide excision and reconstruction with nonvascularized fibular graft may benefit to prevent dislocation and provides an excellent functional outcome.
