Construction of railway embankments on loose beds without using any methods of soil improvement (e.g. stone columns in silt and clay beds, deep soil mixing method, jet grouting and also using micropiles individually or in groups form) leads to  reduction of embankment slope gradient, which significantly increases the volume of soil operation. Generally, micropile as a reinforcing element with t...

The majority of articles on Adiabatic Compressed Air Energy Storage (A-CAES) so far have focussed on the use of indirect-contact heat exchangers and a thermal fluid in which to store the compression heat. While packed beds have been suggested, a detailed analysis of A-CAESwith packed beds is lacking in the available literature. This paper presents such an analysis. We develop a numerical model ...

Laboratory education in science and engineering often entails the use of test-beds equipped with costly peripherals for sensing, acquisition, storage, processing, and control of physical behavior. However, costly peripherals are no longer necessary to obtain precise measurements and achieve stable feedback control of test-beds. With smartphones performing diverse sensing and processing tasks, t...

Fabrication of tunable fine textures on solid metal surfaces often demands sophisticated reaction/processing systems. By exploiting in situ polymerization and self-assembly inorganic adducts derived from liquid metals (the so-called HetMet reaction) with concomitant solidification, films texture are readily fabricated. Serving as a natural dimensional confinement, interparticle pores capillary-...

A demand-driven pressure swing adsorption biogas upgrading application is modelled using monolayer and multilayered (bilayer) beds, to gain insight on the impact of adsorbent pellet size overall performance such processes. Pellet radii in range 0.1–2.4 mm were studied, for fixed cycle settings column dimensions. Varying influences sorption kinetics flow resistance, resulting existence an optimu...

The Pennsylvanian Minturn Formation in north-central Colorado exhibits a complex stratigraphic architecture of fan-delta deposits that developed in association with high topographic relief in a tectonically active setting. The formation records a wide range of environments including alluvial fan, fluvial, deltaic, and open marine settings. This field trip will examine outcrops of a remarkable ~...

Introduction: Ancient, variably salty, friable, basaltic sedimentary beds with relatively uniform grain sizes and prominent, remarkably shallow crossbedding have now been imaged at the Martian surface by all three Mars rovers, Spirit (MER1), Opportunity (MER2), and Curiosity (MSL). Where they have been found, these beds overlie other, older rocks. Owing to alleged analogies with terrestrial sed...

Abstract During the Middle Miocene, an extensive lake district existed along southern margin of today’s Swabian Alb (Baden–Württemberg). Sediments include a wide range from marls to pure carbonates lacustrine and palustrine origin that contain microbialites studied here. These sediments are part Obere Süßwassermolasse known as Silvana Beds. Macroscopically show distinctive layering with alterna...

The transport of sediment in regions with vegetation plays an important role aquatic ecosystems and landform evolution river deltas. In this study, flow parameters suspended concentration (SSC) within emergent canopy real plant morphology (Typha latifolia) were measured a laboratory channel. T. latifolia is common marsh species multiple thin leaves emerging from tight bundle (culm) at the bed. ...
