mineral based lubricants are used it what type of a/c systems?
A key design change for HFC-134a AC systems compared to CFC-12 systems was the need for different materials and components to accommodate the properties of HFC-134a. HFC-134a operates at higher pressures than CFC-12, necessitating stronger hoses, seals, and components to prevent leaks and ensure reliability. Additionally, the lubricant used in HFC-134a systems had to be changed from mineral oil, typically used with CFC-12, to synthetic oils that are compatible with the new refrigerant.

To develop systems for involving stakeholders in organizational change planning, start by identifying key stakeholders and their interests. Facilitate open communication through regular meetings, surveys, and feedback channels to gather input and address concerns. Create collaborative workshops to co-design solutions, ensuring stakeholders feel valued and engaged in the process. Finally, establish clear roles and responsibilities to maintain accountability and enhance stakeholder commitment throughout the change initiative.
The experimental design is always a key factor in the science inquiry. The experimental design shows the methods that lead to the science.

An organization is a social entity that is goal directed, designed as deliberately structured and cordinated activity systems, and are linked to the external environment. The key factors which affect organizational design are globalization, intense competition, ethics and social responsibility, speed and responsiveness and diversity.
The key features and specifications of the br-rx400 model include a lightweight design, compatibility with various brake systems, and high braking performance. It also has a durable construction and easy installation process.
The key design features that differentiate a modern penny farthing from its historical counterpart include the use of lightweight materials such as aluminum or carbon fiber for the frame, improved braking systems, pneumatic tires for a smoother ride, and adjustable handlebars for better comfort and control.
when you change key it is called transposing. but when you remain in the same key but change from major to minor ( or any other change within the key) it is called 'change of mode'
