Sand excavations in river beds have compromised the safety of several bridges recent years. Large scale sand mining from is now common Niger Delta, due to necessity reclaiming land for development purposes and meet construction needs region. There currently no regulation as where can be mined channels because lack adequate understanding risks coastal infrastructure involved with its abstraction...

Surface moisture is an important supply limiting factor for aeolian sand transport, which is the primary driver of coastal dune development. As such, it is critical to account for the control of surface moisture on available sand for dune building. Optical remote sensing has the potential to measure surface moisture at a high spatio-temporal resolution. It is based on the principle that wet san...

The present work is focused on the study of fluidization behaviour of biomass and sand mixtures in a laboratory scale test set up. The biomass materials used during the experimentation were rice husk, bagasse and sawdust. Two different particle sizes of silica sands were used in forming the mixture. The percentages of biomass in the mixtures were 2%, 5%, 10% and 15% by weight. The minimum fluid...

The NW-trending Denizli basin of the SW Turkey is one of the neotectonic grabens in the Aegean extensional province. It is bounded by normal faults on both southern and northern margins. The basin is filled by Neogene and Quaternary terrestrial deposits. Late Miocene- Late Pliocene aged Kolankaya formation crops out along the NW trending Karakova uplift in the Denizli basin. It is a typical flu...

Devonian black shales that were deposited on the North American craton contain abundant Tasmanites cysts. Although these are typically flattened because of compaction, a small proportion of cysts is filled with diagenetic silica. The latter are spherical to ellipsoidal (0.1-0.5mm), and filled with chalcedony, microand megaquartz, and with single quartz crystals. Chalcedonic cyst fillings are pr...

Soil desiccation is recognized as a potentially robust remediation process for the deep vadose zone. Before this technique can be deployed, several techniques issues need to addressed. In this paper, two experiments are described addressing the issue of potential energy limitations to reduce soil moisture. The experiments are conducted in wedge-shaped, intermediate-scale flow cells. The experim...

A dry-inoculation method for almonds and walnuts was developed to eliminate the need for the postinoculation drying required for wet-inoculation methods. The survival of Salmonella enterica Enteritidis PT 30 on wet- and dry-inoculated almond and walnut kernels stored under ambient conditions (average: 23 °C; 41 or 47% RH) was then compared over 14 weeks. For wet inoculation, an aqueous Salmonel...

The Copper Harbor Conglomerate is a Mesoproterozoic (1.09 Ga) freshwater sedimentary sequence that outcrops in the Upper Peninsula of Michigan. The formation was deposited during infilling of the failed Midcontinent Rift and contains fluvial, lacustrine, and alluvial fan facies. This study describes and analyzes the formation of small domal structures preserved in fluvial sandstone facies withi...

An experiment with different filter beds and macrophytes was carried out to study their phytoremediation capacity on the efficiency of domestic wastewater treatment through constructed wetland (CW) from November March 2017-18 at University Agricultural Sciences, Dharwad campus, Karnataka. Twenty combinations involving five types (FB-1: gravel, FB-2: gravel-sand-gravel, FB-3: gavel-sand-brick-gr...

Growing human population has caused the increase in the tempo of construction activity world wide.Since new techniques are either available or constantly emerging the sites which have been deemed unsuitable are being put to use for the construction of new and challenging structures. The foundations for the residential buildings in paddy fields and marshy land with water table near the ground le...
