The relationship between the secondary vascular system and the lymphatic vascular system in fish

Biological Reviews, Volume 99, Issue 6, Page 2108-2133, December 2024.
ABSTRACT New technologies have resulted in a better understanding of blood and lymphatic vascular heterogeneity at the cellular and molecular levels. However, we still need to learn more about the heterogeneity of the cardiovascular and lymphatic systems among different species at the anatomical and functional levels.

Significant effect of compositional grading on SAGD performance in a fractured carbonate heavy oil reservoir

Journal of Petroleum Exploration and Production Technology, 2019
In reservoir simulation, the fluid composition is usually assumed uniform for the whole reservoir, while in many reservoirs, oil and gas composition changes with depth. This phenomenon which is known as compositional grading could be significant in heavy
