Polyethylene glycol 3350 NR (Non-Rx, non-prescription) does not contain electrolytes. It acts as an osmotic laxative used to treat occasional constipation by drawing water into the bowel to soften stools and increase bowel movements. Unlike some other laxative types that can affect electrolyte balances due to their mechanisms of action, polyethylene glycol works without directly adding or depleting electrolytes in the body. However, consulting with a healthcare provider before using it is important, especially for individuals with certain health conditions or concerns about electrolyte balance.

Comparing the strength of polyurethane and epoxy depends on the specific application and the forms of these materials. Epoxy is generally more rigid, making it excellent for applications requiring strong adhesion and high structural strength. It has a superior bond strength on a variety of surfaces, including concrete and metal, and is better at resisting chemical corrosion. On the other hand, polyurethane is more flexible, which makes it more resistant to impact and abrasion. This flexibility allows polyurethane to absorb impacts without cracking, making it ideal for surfaces that undergo significant movement or expansion. Additionally, polyurethanes are often preferred for their durability in harsh weather conditions, as well as for their resistance to UV light, which can degrade epoxy over time. Thus, while epoxy may offer superior tensile strength and bonding capabilities, polyurethane provides better performance in applications that require flexibility, impact resistance, and environmental durability.

To fix yarn audit vulnerabilities, start by running `yarn audit` to identify specific issues within your project dependencies. Prioritize addressing high severity vulnerabilities first. For each, follow these steps: 1. Try updating the vulnerable package to the latest version using `yarn upgrade package-name`. If direct dependencies are affected, this may resolve the issue. 2. If the vulnerability is in a transitive (indirect) dependency, consider using `yarn upgrade package-name --latest` to update the dependency tree or `resolutions` in your `package.json` to force a specific version of the vulnerable package. Note: Use the `resolutions` field with caution as it can lead to compatibility issues. 3. Check the npm or GitHub advisories for the vulnerability to understand its impact and any workarounds. 4. If an update or resolution isn't available, consider removing the affected package if it's not critical to your project or seeking alternative packages. Regularly repeat this process as new vulnerabilities are reported and patches are released.
