Depositional textures and structures

1972
The most obvious and characteristic feature of sedimentary rocks is bedding or stratification,1 by which is meant both the presence of recognizably different beds or strata in a sedimentary succession, and the presence within any one bed of a fine lamination or texture which is connected with its deposition (Fig. II-1).

Percolation and structural properties of particle deposits

Physical Review E, 1995
We investigate the percolation properties of configurations of spherical particles deposited by a generalized ballistic deposition model. In this model, a tuning parameter a is introduced for controlling the relative efficiency of two mechanisms: direct deposition and deposition by following the path of steepest descent on previously deposited ...

Structural Study of Arthropathic Deposits

1984
Destructive joint arthropathics and connective tissue diseases are often associated with the presence of crystalline deposits. One such deposit is hydroxyapatite; a mineral frequently observed in the articular and intra-articular cartilage of patients suffering from acute synovitis or more progressive arthropath ics, for example osteoarthritis.

Modeling Deposit Erosion in Internal Turbine Cooling Geometries

Journal of Engineering For Gas Turbines and Power, 2019
Experiments were performed to study the erosion of deposit structures due to large particle impacts (>5 μm). Cone-shaped dust deposits were created in an oversized (6.35 mm diameter) impingement cooling jet at 811 K with 0–5 μm Arizona road dust (ARD).

Structural characterization of MAPLE deposited lipase biofilm

Applied Surface Science, 2014
tLipases (triacylglycerol ester hydrolases) are enzymes used in several industrial applications. Enzymesimmobilization can be used to address key issues limiting widespread application at industrial level.Immobilization efficiency is related to the ability to preserve the native conformation of the enzyme.MAPLE (Matrix Assisted Pulsed Laser Evaporation)

Structure of simulated colloidal deposits

Colloids and Surfaces, 1989
Abstract Computer simulation is a powerful tool for studying at a fundamental level the various factors influencing the morphology of colloidal structures deposited in the form of sediments or filter cakes. The complexity of numerical methods covers a wide range: from simple models, in which particles move in random walks or straight lines, and where

The Structural Consequences of Calcium Crystal Deposition

Rheumatic Disease Clinics of North America, 2014
Calcium pyrophosphate dihydrate and basic calcium phosphate (BCP) crystals are the most common calcium-containing crystals associated with rheumatic disease. Clinical manifestations of calcium crystal deposition include acute or chronic inflammatory and degenerative arthritides and certain forms of periarthritis.

Structure of Laser-Deposited Fe/Al Multilayers

Materials Science Forum, 1998
Fe/Al nm-period multilayers deposited by pulsed laser deposition were investigated by conversion electron Mossbauer spectroscopy and transmission electron microscopy. No Fe-Al intermetallic phases were found in the intermixed transition range with an Al-concentration range of 20-60 at.%. A qualitative depth distribution of the impurity concentration in

Structural Studies of Sedimentary Deposits

Geologiska Föreningen i Stockholm Förhandlingar, 1965
Abstract The apposition fabric in different sedimentary deposits is discussed from genetic and structural points of view. The preferred orientation of most particle sizes, transported in contact with a frictional substratum, is usually transverse to the direction of transport.
