general concept and major emphasis on off-pump coronary artery bypass surgery (opcab) is maintaining quality of care and patient safety while reducing cost and resource utilization. opcab probably avoids the potential complications of cardiopulmonary bypass. however its acceptance depends on clinical and economic outcome. the aim of this study is to compare clinical and economic outcome of off-...

Distilled water in the laboratory is highly important since it a basic requirement lab work and/or research. The large use of distilled Faculty Mathematics and Natural Sciences University Lambung Mangkurat (FMIPA ULM) obliged to depend on its own by providing equipment produce water. efficiency low during producing one liter due 35 liters needed. Several studies have conducted focusing energy a...

We propose a scalable state estimator with wave filter for surface vessels. The filter is shown to be either globally or locally exponentially stable depending on configuration. Performance is illustrated using actual data from a full scale semi-submersible drilling rig.

The vision of exploring extraterrestrial water findings employing a remotely operated submersible, as proposed by JPL/NASA for the investigation of the possible ocean underneath the frozen crust of Jupiter’s moon Europa, is now taking a step further into fulfilment. The Ångström Space Technology Centre has developed a sophisticated vehicle concept based on microtechnology for most of the naviga...

Unimolecular submersible nanomachines (USNs) bearing light-driven motors and fluorophores are synthesized. NMR experiments demonstrate that the rotation of the motor is not quenched by the fluorophore and that the motor behaves in the same manner as the corresponding motor without attached fluorophores. No photo or thermal decomposition is observed. Through careful design of control molecules w...

The aim of this project was to develop the state estimation system for an autonomous underwater vehicle called Kambara. This project took place at the Research School of Information Sciences in cooperation with the Department of Engineering at the ANU. The purpose of the state estimation system was the filtering of data from a triaxial accelerometer, rate gyroscope, depth sensor and compass/inc...

Introduction: Coronary artery bypass grafting is a surgical operation that bypasses atherosclerotic coronary vessels and restores blood flow to the ischemic zone of hearts. And two different conventional methods are ON-pump CABG, and Off-pump CABG.  Altogether, the efficacy and safety of these two types of surgical procedures are still under debate. In this study, we aim to com...
