Abstract. Active geological processes often generate a ground surface response such as uplift, subsidence and faulting/fracturing. Nowadays remote sensing represents key tool for the evaluation monitoring of natural hazards. The use unmanned aerial vehicles (UAVs) in relation to observations hazards encompasses three main stages: pre- post-event data acquisition, monitoring, risk assessment. mu...

polyanionic cellulose polymer is used as an additive in drilling mud in order to decrease water loss and mudcake- thickness. in this study effect of bulk and nanosize polyanionic cellulose on water loss and mud-cakethickness in mud drilling is investigated. polyanionic cellulose nanoparticles are made by using of ball milling. size of nanoparticles is measured by particle size analyzer. polyani...

Penelitian ini menyajikan hasil pengolahan data SAR dengan metode Permanent Scatterer Interferometric (PS-InSAR) yang bertujuan untuk menganalisa pola dan nilai deformasi muka tanah akibat manifestasi gunung lumpur di wilayah Cekungan Jawa Timur. Dengan menggunakan PS-InSAR pada time series citra L-band ALOS PALSAR 1 tahun 2007-2009 C-band Sentinel 1A 2015-2019, besarnya didapat dapat sampai ke...

The diversity of anaerobic microorganisms in terrestrial mud volcanoes is largely unexplored. Here we report the isolation a novel sulfate-reducing alkaliphilic bacterium (strain F-1T) from volcano located at Taman peninsula, Russia. Cells strain F-1T were Gram-negative motile vibrios with single polar flagellum; 2.0–4.0 µm length and 0.5 diameter. temperature range for growth was 6–37 °C, an o...

Mud Recycle is a process option for cane diffuser factories; it eliminates the need for a filter station by using the bed of shredded cane in the diffuser to separate out mud solids from the juice. This paper describes the Mud Recycle system at Maidstone mill and presents the results of a Mud Recycle trial that was carried out during the 1998 season. Maidstone switched to Mud Recycle on a perma...

The Mariana forearc system, in the northwestern Pacific, is known as only convergent margin setting with currently active serpentine mud volcanism. Fantangisña serpentinite volcano lies 62 km west of trench, within influence North Equatorial Current (NEC). Cores recovered by International Ocean Discovery Program (IODP) Expedition 366 contain pelagic sediments overlying layered deposits. At bott...
