Petrogenesis of Tertiary Andesite Lava Flows Interlayered with Large-Volume Felsic Ash-Flow Tuffs of the Western USA

Pulsatory andesite lava flow at Bagana Volcano

[1] Using a time series of TerraSAR-X spaceborne radar images we have measured the pulsatory motion of an andesite lava flow over a 14-month period at Bagana Volcano, Papua New Guinea. Between October 2010 and December 2011, lava flowed continuously down the western flank of the volcano forming a 3 km-long blocky lava flow with a channel, levees, overflows and branches. We captured four success...

Dynamic Properties of Ash - Flow Tuffs by Won

the pathology of historical texts translation: a study of persian translations of 7th volume of cambridge history of iran

ترجمه با گسترش زبان آغاز شده و اهمیت آن روز به روز افزایش می یابد، و برای اولین بار به عنوان شاخه ای از دانش و روشی برای انتقال علوم، فرهنگ و تجربه در در دوره قاجار در ایران آغاز شد. در حقیقت متون تاریخی از اولین متونی هستند که در ایران ترجمه شدند چرا که به سیاستمداران آن دوره کمک می کردند تا به علل موفقیت جهان غرب و پیشرفت هایشان در طول تاریخ پی ببرند، بنابراین به تدریج ترجمه این گونه متون رون...

new semigroup compactifications via the enveloping semigroups of associated flows

this thesis deals with the construction of some function algebras whose corresponding semigroup compactification are universal with respect to some properies of their enveloping semigroups. the special properties are of beigan a left zero, a left simple, a group, an inflation of the right zero, and an inflation of the rectangular band.

Lava Flows in the Tharsis Region of Mars: Estimates of Flow Speeds and Volume Fluxes

The goal of this study was to characterize the eruptive behavior of Olympus Mons, Mars, by estimating flow speeds and volume fluxes for lava flows produced from various vents on the volcano. During my fellowship, I have made width, depth and ground slope measurements of 65 lava tubes and 271 channels from 56 MOC images and 65 THEMIS images of Olympus Mons. The data show that channels are more n...
