Two simple algorithms are suggested here to correct for the effect of diffusion and diagenetic sulfate reduction on radiocarbon age determination of marine porewater. The correction algorithms were developed from mass balances of sulfate, dissolved inorganic carbon (DIC), and 14C of the DIC (CDIC) in vertical concentrations profiles in porewater starting from the sediment water interface. The a...

This study was undertaken to determine the levels of protein C antigen and activity and protein C inhibitor in sequential plasma samples of disseminated intravascular coagulation (DIC) patients. Our normal range for both protein C antigen and activity is 70 to 130 U/dL. and protein C inhibitor is 65 to 135 U/dL. A decreased level of protein C activity was found in 96% of the plasma samples from...

A full field method for the description of in-plane strain fields is applied for improving Asphalt Mixture cracking behaviour insights. A Digital Image Correlation (DIC) system based on the Least Square Matching technique is used to compute strains and depict crack path in the process from microcrack initiation to failure. A Brazilian test was performed using hole-notched specimens. The test ge...

We investigate the formation of microscopic patterns in a copper single crystal deformed in a shear experiment. Using high-resolution electron backscatter diffraction (EBSD) imaging, we find a band-like microstructure consisting of confined areas in the sample with rotated lattice. Digital image correlation (DIC) allows us to exactly determine the macroscopic state of deformation of the sample....

In this paper, a novel chord transition representation (Cambouropoulos 2012), that draws on the interval function between two collections of notes proposed by Lewin (1959), is explored in a harmonic recognition task. This representation allows the encoding of chord transitions at a level higher that individual notes that is transposition-invariant and idiom-independent (analogous to pitch inter...

A new scheme for digital image correlation (DIC), i.e., short time series DIC (STS-DIC) is proposed. Instead of processing the original deformed speckle images individually, STS-DIC combines several adjacent deformed speckle images from a short time series and then processes the “averaged image”, for which deformation continuity over time is introduced. The deformation of several adjacent image...

In recent years there have been an increasing nunmber of articles and studies on the topic of disseminated intravascular coagulation. -' 2 3 It is not a newly found phenomenon. The syndrome was identified in general terms in a 1959 article by William Crosby. 4 Numerous terms, including defibrination syndrome,) diffuse intravascular coagulation,: and consumpltive coagulopathy7 have been used to ...

Concentration of a nonfluorescent solution was determined in a 100-nm scale channel using a differential interference contrast thermal lens microscope (DIC-TLM). The DIC-TLM detects a refractive index change induced by sample heating as phase contrast. Concentration measurement was first performed in a nanochannel which is 21 m wide and 500 nm deep. The limit of detection (LOD) was 2.4 M and th...
