Cross-Bedding
<p>Cross-bedding is formed in both terrestrial and marine environments. The littoral deltaic type is probably the most common. It also occurs in lake deltas, fluvial bars and channel fills, beaches, sand dunes, and as eolian deposits modifying any of the others. It ranges in size from microscopic …

Comparison of Bedding Thickness in some Sedimentary Materials
… and sedimentologists, utilize terms to describe bedding thicknesses such as "thin", “medium" and "thick" that are poorly defined. Kelley, who discussed the early unsuccessful attempts to define bedding, believed that such terms should have an accepted meaning through the establishment of standard …

Effects Of Bedding Void On Internal Moment Increase In Concrete Pipes
… As the void develops in the middle third of the bedding under the invert, pressure redistribution occurs to the outer two thirds of the bedding. As the stress increases in the outer portions of the bedding, more subgrade material is washed into the pipe when it is not under pressure, making the …

Characterizing water holding capacity and total solids of manure-bedding mixtures
… and eliminates the need for runoff control. Bedding materials are used to absorb excess moisture, improve animal comfort and reduce negative environmental impacts from these livestock facilities. Various biomass types can be used as potential bedding material, such as corn stover, wheat straw …

Burrows and bedding : site taphonomy and spatial archeaology at Tortoise cave
Excavations at the Late Stone Age site of Tortoise Cave, a shell midden accumulation in the Western Cape, South Africa, were carried out from 1978 to 1983. The author supervised this project from 1981 onwards with the aim of expanding the cultural sample and defining more clearly the stratigraphic …

RECYCLED MANURE SOLIDS AS DAIRY COW BEDDING SUBSTRATES: MICROBIOLOGICAL ASPECTS RELATED TO MAMMARY GLAND HEALTH
… per lettiere a base di calce (lime-based bedding conditioner, LBC) sulle proprietà fisico-chimiche e sulle conte microbiche dei RMS. Il LBC si è dimostrato efficace nell'aumentare il pH e il contenuto di sostanza secca (dry matter, DM), con concentrazioni più elevate correlate a una …

Determination and assessment of procedures of the pour-through nutrient extraction procedure for bedding flats and plug trays
… Pour-through nutrient extraction procedure for bedding flats and plug trays. The Pour-through technique involves pouring a prescribed volume of water on a recently irrigated medium, then collecting and analyzing the leachate to predict nutrient availability in the medium. The volume of water …

A poultry litter marker gene correlates with pathogen and indicator bacteria deposition on, growth in and transport from poultry bedding
… the deposition rate of microorganisms on poultry bedding during the growth of poultry. The studies were designed to simultaneously evaluate the growth or decay of microorganisms after deposition on the poultry bedding (i.e., wood shavings). A secondary objective of this study was to determine if …

Bedding as a Factor in the Survival and Total Height of Two Year Old Planted Loblolly Pine Seedlings in East Texas
… in an attempt to determine the effect of bedding in intensive site preparation on the total height and survival of two year old loblolly pine (Pinus taeda, L.) seedlings planted on bottomland and upland sites. Forty row (or lineal) plots 100 feet long were established on machine planted …

Architecture and origin of fluvial cross-bedding based on flume experiments and geological examples field case studies: Rillo de Gallo, Spain and Northumberland, UK
… topography. New ways of classifying cross-bedding were developed to allow analyses of patterns and relationships between set geometry, flow behaviour and stratigraphic position within sedimentary sequences. The amount and variation in divergence between scour trend and scour-fill laminae …

A laboratory investigation of the effect of flow rate and bedding characteristics on the interaction of a vertical water jet with an idealised soil medium
… which interacts with the surrounding soil (bedding material) in a manner that causes the granular medium to fluidise. This fluidisation process was seen to exhibit complex behaviour, which restricted shallow leaks under relatively high pipe pressures from growing and reaching the bed …

Slash Mulching and Incorporation as Mechanical Site Preparation for Pine Plantation Establishment and Subsequent Effects on Soil Moisture and Site Hydrology
… four blocks and six treatments: (i) conventional bedding, (ii) strip surface mulching with bedding, (iii) strip surface mulching with tillage and bedding, (iv) broadcast mulch without bedding, (v) broadcast mulch with bedding, and (vi) flat planted control. The pocosin study was organized as a …

An experimental and numerical study on the fracturing processes in Opalinus shale
… anisotropy, which is caused by naturally formed bedding planes. Natural bedding planes are weak zones along which cracks can initiate and propagate. As a consequence, the effect of bedding planes on crack initiation and propagation has not been captured well in previous models. A series of …

Orientations and magnitudes of paleostress in the Great Valley Province of northern Virginia
… compression axes oriented sub-perpendicular to bedding possibly indicating either thrust sheet loading or stress refraction associated with folding. Samples in which calcite grains from both fracture fills and earlier matrix cements were measured are characterized by a bimodal distribution of …

Long term effects of wet site timber harvesting and site preparation on soil properties and loblolly pine (Pinus taeda L.) productivity in the lower Atlantic Coastal Plain
… of site preparation as the whole plot factor (bedding, disking with bedding, disking, and no site preparation), and two levels of traffic as the subplot factor (primary skid trail, no obvious traffic). After 23 years, bedding and disking with bedding treatments effectively enhanced soil …

The Role of Horizontal Stress in the Formation of Valley Stress Relief Features in Flat-Lying Sedimentary Rocks
… geologic sequence including plastic slip along bedding is modeled using the results of this analysis. Parameters examined as part of this stage of the study include bedding thickness as well as bedding plane strength. Rock material between bedding surfaces remains elastic. Based upon the results …
