Abstract Central Sulawesi Province is one of the areas in Indonesia that prone to large earthquakes. Balaroa, Petobo, and Sibalaya were among most fatalities damaged facilities infrastructure due earthquake on September 28th 2018. Around Balaroa Village, besides huge damages Perumnas Housing, area around housing was also affected, for example Jamur, Kelor, Labu streets, many houses buildings da...

B. C. O’Kelly, Trinity College Dublin The authors rightly state that the strength gain ratio over the plastic range (R 1⁄4 cu(PL)=cu(LL)) is often about 100 for many soils, although there is no theoretical basis for a universal value of 100, and that other researchers have postulated cu(PL) 170 kPa and R up to as high as 170. The LL, PL and R values largely depend on the grading and mineralogy,...

A spark plug fuel injector (SPFI), which is a combination of a fuel injector and a spark plug was developed with the aim to convert any gasoline port injection spark ignition engine to gaseous fuel direct injection (Mohamad in Development of a spark plug fuel injector for direct injection of methane in spark ignition engine. PhD thesis, Cranfield University, 2006). A direct fuel injector is com...

introduction: this in vitro study aims to evaluate the coronal and apical sealing ability of gutta-percha (gp) root filling used with either mineral trioxide aggregate (mta), new endodontic cement (nec) or ah26 as filler/sealers. materials and methods: forty eight single-rooted extracted teeth were selected, decoronated and then instrumented. samples were randomly divided into three experimenta...

AIM To compare the apical sealing in mesio-buccal canals of extracted molars obturated with low-temperature thermoplasticized gutta-percha or cold lateral condensation techniques using a .06 or a .02 mm/mm tapered gutta-percha master cone. The secondary aim was to evaluate the depth of spreader penetration in root canals using a .06 or a .02 mm/mm tapered gutta-percha master cone. METHODOLOGY...

the liquefaction resistance of soil can be evaluated using laboratory tests such as cyclic simple shear, cyclic triaxial, cyclic torsional shear as well as field methods like standard penetration test (spt), cone penetration test (cpt) and shear wave velocity (vs). in this regard, this study attempts to compare the results of the spt based on the simplified procedure proposed by seed and idriss...

for a determination of soil characteristics one should have access to instruments that can measure these characteristics, including: soil penetration resistance with high accuracy. one of the accurate instruments commonly employed in soil penetration determinations is cone penetrometer. this apparatus, by measuring soil cone index at different soil depths can provide useful about information ab...
