In this study, the method according to Indonesian National Standard (SNI) was applied. The objects test in form of cylindrical concrete which fine aggregate pumice sand and ordinary sand. made were tested for compressive strength. There 6 study with a size 15 cm x 30 cm. detail, 3 sand, while other coarse all crushed stone. result shown use as substitute can reduce strength by 23.53%. However, ...

The transport characteristics of iron nanoparticles prepared with a green tea, polyphenol-rich solution, were investigated for two granular media, pure silica sand and sand coated with aluminium hydroxide. The GT-nZVI injection caused a sharp decrease in the effluent pH and increase in the redox potential, which is attributed to the presence of free Fe and polyphenols in the suspension, respect...

The collaborate studies of clinical application of Extracorporeal Shock Wave Lithotripsy (ESWL) using Sonolith 2000, performed at Departments of Urology of Nara Medical University, the University of Tokai School of Medicine and Wakayama Medical College between March and August 1987, were reported. In total 155 ESWL sessions were carried out on 111 patients suffering from in total 119 upper urin...

Duodenal duplication cysts are rare congenital malformations. Most symptomatic cases are diagnosed in children and usually present with obstructive findings or bleeding symptoms. Treatment traditionally involves surgical resection, which can be often difficult because of the close proximity of the cysts to the papilla and bilopancreatic confluence. Endoscopic therapy has been used as an alterna...

Fruit brown rot caused by Monilinia spp. is the most important fungal disease of stone fruits worldwide. Several phenotyping protocols to accurately characterize and evaluate brown rot infection have been proposed; however, the outcomes from those studies have not led to consistent advances in resistance breeding programs. Breeding for disease resistance is one of the most challenging objective...

Abstract For sustainable development, sand-mixed concrete has been paid more and attention by researchers. In order to study the mechanical properties of sand-gravel concrete, five temperature levels natural cooling water were considered, sand-stone after high tested.. desert sand temperature, this paper designs a single factor test with replacement rate as variable. Five are watering adopted t...
