Temporal Variations in Fibril Orientation

Temporal and Spatial Variations of Finfish Bycatch of Cutlassfish Trawl in Bushehr and Hormozgan Marine Waters, the Northern Persian Gulf

The spatial and temporal variations of finfish bycatch assemblage cutlassfish trawl were compared in two fishing areas (Hormozgan and Bushehr). Data were collected on board of commercial vessels in the fishing grounds of Trichiurus lepturus in Bushehr and Hormozgan marine waters between early May 2010 to late November, 2010. There was a significant difference in the bycatch assemblages bet...

Investigation of Variations of Isotropic g- and A- Values with Orientation of Trapped O2−, N2− and Cl2− Radicals in KCl and NaCl Crystals

Analysis of the Spatial and Temporal Suspended sediment of Qarahsu Drainage Basin

This study is aimed at estimating suspended sediment load in watersheds using hydro-climatic factors with the intent to determine spatial and temporal variations of sediment yield in Qarah Su drainage basin, Ardebil Province. For this study, data from seven rain gauge and hydrometric stations during a 22-year period were used. The research was based on statistical regression analysis between va...

3D collagen orientation study of the human cornea using X-ray diffraction and femtosecond laser technology.

PURPOSE To study the distribution and predominant orientations of fibrillar collagen at different depths throughout the entire thickness of the human cornea. This information will form the basis of a full three-dimensional reconstruction of the preferred orientations of corneal lamellae. METHODS Femtosecond laser technology was used to delaminate the central zones of five human corneas into t...

A methodology for the systematic and quantitative study of cell contact guidance in oriented collagen gels. Correlation of fibroblast orientation and gel birefringence.

Despite the likely role of contact guidance in every physiological process involving cell migration, its study in a three-dimensional tissue-equivalent environment has been precluded, heretofore, by inherent difficulties in systematically preparing well-defined contact guidance fields and quantifying the resultant contact guidance. Here, we describe a novel use of a magnetic field to orient col...
