We present simulated optical light curves of super-Eddington tidal disruption events (TDEs) using the zero-Bernoulli accretion (ZEBRA) flow model, which proposes that during phase, disc is quasi-spherical, radiation-pressure dominated, and accompanied by production strong jets. construct for both on- off-axis (with respect to jet) observers account anisotropic nature jetted emission. find at wa...
Udara adalah elemen penting bagi kehidupan, agar makhluk hidup dapat secara optimal, mereka perlu menjaga dan meningkatkan kualitasnya. Kualitas udara dalam ruangan erat kaitannya dengan efisiensi kerja kesehatan manusia. Pencemaran suatu keadaan dimana kualitas rusak tercemar zat-zat, baik yang tidak berbahaya maupun Pada umumnya pencemar berupa gas beracun (hampir 90%) dari partikel padat. Di...

Multirotor helicopters are increasingly popular platforms in the robotics community. Making them fully autonomous requires accurate state estimation. We review an improved dynamic model for multirotor helicopters and analyze the observability properties of an estimator based on this model. The model allows better use of IMU data to facilitate accurate state estimates even when updates from a se...
We present the first high resolution (R=20000–45000, corresponding to 14 km/s at 4200Å to 6.6 km/s at 9000Å ) observations of the optical afterglow of Gamma Ray Bursts. GRB 020813 and GRB 021004 were observed by UVES@VLT 22.19 hours and 13.52 hours after the trigger, respectively. These spectra show that the inter–stellar matter of the GRB host galaxies is complex, with many components contribu...

Fletcher, D. E. (1972). Brit. J. industr. Med., 29, 142-145. A mortality study of shipyard workers with pleural plaques. Mild asbestos effects are seen frequently in shipyard workers. It is known that exposure of this type may be associated with mesothelioma, but it is not generally thought that an increased bronchial carcinoma risk exists unless there is pulmonary fibrosis. A number of cases o...
