Heart valves are functionally complex, making surgical repair difficult.
The EGJ is anatomically and physiologically complex, making it vulnerable to dysfunction by several mechanisms.
Clerkship applications are competitive and complex, making such input highly beneficial.
The CHESS-U vacuum system is compact and complex, making for a challenge to find places for all components.
Hydrocarbon reactions can become very complex, making the kinetic relations difficult to describe, not conforming to any power law.
However, interactions among groups of people, biota, and geographies are inherently complex, making it difficult to tease apart reality from myth and sustainability from unsustainability.
Even modest upgrades and changes in equipment, he maintains, are highly complex, making it difficult to achieve the required safety standards without extensive domestic expertise in this area.
What happened next is a matter of some dispute, though it is certainly an example of how complex making real change here can be.
As expected, under oxidative atmosphere, the kinetic process becomes more complex, making more difficult the detecting of single-step reactions, especially for carbon-phenolic.
These factors are determined by broader forces, the underlying causes of deforestation, but the links are complex making global generalizations difficult.
