Here, physicochemical aspects of N-H tautomerism were investigated and discussed from both theoretical and experimental point of views through ab initio and polarized photoluminescence methods, respectively.Bali, Sumbawa, and Lombok regions are located in active tectonic influence by Indo-Australia plate subducts beneath Sunda plate in southern part and local back-arc thrust in northern part the region. Some active volcanoes also lie from eastern part of Java, Bali, Lombok and Sumbawa regions. Previous studies have conducted subsurface seismic velocity imaging using regional and global earthquake data around the region. In this study, we used P-arrival time from local earthquake networks compiled by Meteorological, Climatological and Geophyiscal Agency of Indonesia (MCGA), Indonesia within time periods of 2009 up to 2013 to determine seismic velocity structure and simultaneously hypocenter adjustment by applying seismic tomography inversion method. For the tomographic inversion procedure, we started from 1-D initial velocity structure. We evaluated the resolution of tomography inversion results through checkerboard test and calculating derivative weight sum (DWS). The results show fairly clearly high seismic velocity of subducting Indo-Australian and low velocity anomaly around volcano regions. The relocated hypocenters seem to cluster around the local fault system such as back-arch thrust fault in northern part of the region and around local fault in Sumbawa regions.In this research, we constructed a mathematical model to study effects of a surfactant on the alteration of contact angle of an oil drop immersed in a surfactant solution and sticked on a rock surface. The model involves parameters such as the density and viscosity of the fluids, the gravity, and the property of the surface which is characterized by so called the slip coefficient. The front-tracking method is used to solve numerically the free boundary motion of the interface. To maintain the conservation of mass during the numerical procedure, a weighted factor with a certain condition is introduced to calculate the update surfactant concentration, for each iteration. By this study, the factors that affect the changes of the contact angle was investigated.Techniques of Minimally invasive surgery(MIS) is utilize emerging technologies for new techniques that offer greater patient care and more options over convensional open surgery. MIS is a surgical technique in which short, trochars are inserted through small incisions Comparison with open surgery, MIS has some advantages, such as less damage to muscle tissue, creating a faster recovery for the patient. Currently, MIS has been applied in limited cases in Indonesia. The application MIS on the clinical situation is required advance technology and surgeons must be trainned to operate MIS devices, since MIS procesure required particular eye-hand coordination that 76
