Stress-Induced Nitrogen and Oxygen Segregation and Complexing Investigated by High Resolution Synchrotron FTIR
Nitrogen doped Czochralski (N-CZ) and Float Zone (N-FZ) silicon were measured by high resolution synchrotron Fourier Transform IR spectroscopy (HR-FTIR). The chemical complexes were analyzed in specific regions with known extended defects, i.e., denuded or precipitated regions of annealed N-CZ Si wafers, in N-FZ Si with ring defects and on “N-Skin” region. The absorption lines were assigned to ...
متن کاملInduced Somatic Segregation in Aspergillus Nidulans.
ETEROZYGOUS diploid strains of Aspergillus nidulans spontaneously proHduce segregant clones belonging to three classes: diploid segregants which have undergone mitotic crossing over; haploid segregants with random redistribution of whole chromosomes (PONTECORVO, TARR GLOOR and FORBES 1954) ; and "nondisjunctional" segregants with all the markers on both branches of one chromosome in the homozyg...
متن کاملQuantifying turbulence-induced segregation of inertial particles.
Particles with different density from the advecting turbulent fluids cluster due to the different response of light and heavy particles to turbulent fluctuations. This study focuses on the quantitative characterization of the segregation of dilute polydisperse inertial particles evolving in turbulent flow, as obtained from direct numerical simulation of homogeneous isotropic turbulence. We intr...
متن کاملIsotopic segregation between sympatric seabird species increases with nutritional stress.
Dietary segregation is essential for the coexistence of closely related species of animals. However, little is known about how changes in availability of food resources might affect trophic interactions of wild animals breeding in sympatry. Here, we examined how interannual variations in relative food availability (as reflected in blood levels of stress hormone corticosterone, CORT) affect food...
متن کاملAsymmetric Damage Segregation Constitutes an Emergent Population-Level Stress Response.
Asymmetric damage segregation (ADS) is a mechanism for increasing population fitness through non-random, asymmetric partitioning of damaged macromolecules at cell division. ADS has been reported across multiple organisms, though the measured effects on fitness of individuals are often small. Here, we introduce a cell-lineage-based framework that quantifies the population-wide effects of ADS and...
