Abstract We describe and interpret deposits associated with the final Ubehebe Crater-forming, phreatomagmatic explosive phase of multivent, monogenetic volcanic center. volcano is located in Death Valley, California, USA. Pyroclastic occur four main facies: (1) lapilli- blockdominated beds, (2) thinly bedded lapilli tuff, (3) laminated cross-laminated ash, (4) massive ash/tuff. Lapilli- block-d...

This paper deals with the study of ECG signals using wavelet transform analysis. The Electrocardiogram (ECG) shows the electrical activity of the heart and is used by physicians to inspect the heart’s condition. Examination of ECG is not easy ,it is tuff task, if noise is added with signal during acquirement. In this paper, denoising techniques for ECG signals based on Decomposition will be com...

T h r e e methods for converting Airborne Visible/Infrared Imaging Spectrometer (A VIRIS) radiance data to apparent surface reflectance were compared using data collected over the Lunar Crater Volcanic Field in Nevada and the Pavant Butte tuff cone in Utah. The methods examined were the empirical line method, radiative transfer modeling (using LOWTRAN 7), and spectral mixture analysis using ref...

Abstract Geothermal energy is one of the mainstay future alternative in Indonesia. One area that believed to have geothermal potential Telaga Tujuh Warna Village Lebong Regency, Bengkulu Province, Manifestations hot springs, mud pools, geysers, sulfur, and presence steam around lake are our beliefs about existence sources area. The purpose this study was determine stratigraphic characteristics ...

In the research described in this paper, studied was sorption capacity of natural and ferric modification of zeolite tuff containing mineral clinoptilolite from the Nižný Hrabovec deposit to remove potentially toxic metals (ionic forms of chromium, nickel, copper and aluminium) from their water solutions. We reported that the Fe (III) zeolite has an enhanced ability to sorption of Cu (II), and ...

This study aimed to evaluate the influence of zeolitic tuff, an air-entraining agent, and different types fibers on compressive strength fracture parameters concrete with increased strength. Notched beams were tested in three-point bending determine concrete. It was established that partial replacement Portland cement (10% by mass) addition agent resulted improvement both (by 3.7% after 28 days...
