Static investment appraisal techniques, such as payback period and accounting rate of return, focus on the initial investment and the expected cash flows over a specific period of time. These techniques do not take into account the time value of money or the changing nature of the investment's cash flows over time. On the other hand, dynamic investment appraisal techniques, such as net present value and internal rate of return, consider the time value of money and the entire stream of cash flows over the investment's life. Dynamic techniques provide a more comprehensive and accurate assessment of an investment's potential profitability and are widely used in financial decision-making. **

Yes, silicone does stick to silicone. When two silicone surfaces come into contact, they tend to adhere to each other due to their similar chemical composition. This property makes silicone a popular material for creating airtight seals and bonding silicone-based products together. **

It is generally not recommended to apply new silicone on top of existing silicone. The new silicone may not adhere properly to the old silicone, leading to potential issues with adhesion and durability. It is best to remove the old silicone completely before applying a new layer to ensure a proper bond and a long-lasting seal. **

Yes, silicone can be applied on top of existing silicone. However, it is important to ensure that the existing silicone is clean and free of any dirt, dust, or residue before applying new silicone. Additionally, it is recommended to use a silicone primer to promote adhesion between the old and new silicone layers. This will help to create a strong bond and ensure a durable seal. **

Silicone lenses are a type of contact lens made with a silicone-based material, which allows for increased oxygen permeability to the eye. This can help reduce the risk of eye infections and improve overall comfort. Silicone hydrogel lenses are a specific type of silicone lens that also includes hydrogel, a water-absorbing material that helps keep the lenses moist and comfortable for longer periods of time. These lenses are popular for their breathability and comfort, making them a popular choice for contact lens wearers. **
