Cohesion01:07

Cohesion

56.5K
Cohesion is the attraction between molecules of the same type, such as water molecules. Water molecules have an overall neutral charge but are polar molecule. An oxygen atom in one water molecule has a partial negative charge that can bind to a hydrogen atom with a partial positive charge in a second water molecule, forming a hydrogen bond. Each water molecule can form up to four hydrogen bonds with other water molecules. Hydrogen bonds are responsible for water's cohesive nature.

Virtual Work for a System of Connected Rigid Bodies

522
Virtual work is a powerful method used to solve problems involving several connected rigid bodies. When the system is in equilibrium, virtual work is zero. This allows the calculation of the resulting forces when a system undergoes a virtual displacement. When attempting to analyze such a system, first, use a free-body diagram, where an independent coordinate represents the configuration of the links, and mark its deflected position resulting from the positive virtual displacement.

Non-conservative Forces01:17

Non-conservative Forces

8.6K
Non-conservative forces are dissipative forces such as friction or air resistance. These forces take energy away from a system as it progresses. Unlike conservative forces, non-conservative forces do not have potential energy associated with them. This is because the energy is lost to the system and cannot be turned into useful work later.
Also unlike their conservative counterparts, they are path-dependent; where the object starts and stops does matter. For example, a grinding wheel applies a...

Ligand Binding and Linkage

5.1K
Allosteric proteins have more than one ligand binding site; the binding of a ligand to any of these sites influences the binding of ligands to the other sites. When a protein is allosteric, its binding sites are called coupled or linked.  In the case of enzymes, the site that binds to the substrate is known as the active site and the other site is known as the regulatory site. When a ligand binds to the regulatory site, this leads to conformational changes in the protein that can influence...

Area of Science:

  • Conservation Biology
  • Spatial Planning
  • Climate Change Ecology

Background:

  • Maintaining habitat connectivity is vital for wolverine (Gulo gulo) populations and other high-elevation species.
  • Climate change poses significant threats to species persistence by altering habitat suitability and connectivity.

Purpose of the Study:

  • To prioritize areas for wolverine connectivity conservation under projected climate change scenarios.
  • To identify privately owned lands suitable for conservation easements to enhance landscape functionality.

Main Methods:

  • Employed a systematic conservation planning framework utilizing integer linear programming.
  • Optimized 10%, 15%, 20%, and 50% of habitat features to identify critical areas for wolverine connectivity.
  • Estimated costs associated with voluntary landowner easements for prioritized areas.

Main Results:

  • Identified 369 to 3,996 private parcels across the four optimization scenarios (10-50% habitat).
  • Estimated median easement costs ranged from $8,762 to $12,220, with total costs from ~$15 million to ~$196 million.
  • Highlighted the potential for voluntary easements to secure long-term landscape functionality for wolverine connectivity.

Conclusions:

  • Optimization models are effective tools for conserving landscape connectivity.
  • This research provides a proactive strategy for engaging landowners and collaborators in conservation.
  • The identified areas and framework can support the conservation of diverse subalpine species facing climate change.
