True, RR Lyrae stars pulsate, but with shorter periods and lower luminosities than Cepheids.
The pulsation periods of the fundamental-mode RR Lyrae stars range from about 0.3 to 1.0 days (Population II pulsators with longer periods are categorized as type II Cepheids), but the vast majority of them have generations longer than 0.45 days.
<h3>Why do RR Lyrae stars pulsate?</h3>
RR Lyrae stars pulse like Cepheid variables, but the nature and histories of these stars is thought to be rather different. Like all variables on the Cepheid fluctuation strip, pulsations are caused by the κ-mechanism, when the ambiguity of ionised helium varies with its temperature.

Answer:
Information technology is not the only focus when implementing ERP. It is of utmost importance for ERP to also focus on budget, business processes, people, business requirements and other areas. Employees must be communicated about changes intended in the future. The value of a system such as ERP is determined by how well its end-users use them. If ERP is made to focus on system architecture alone, the software might be successfully installed, but its implementation will be faulted. The installation of the ERP software might be easy, but the difficulties come in when changing the processes and introducing the new process to the people who will make use of the system. Change is something that is difficult to embrace, especially when they have no idea of the change. Hence, it becomes very important that when implementing ERP, business processes and people, and not just information technology and systems are consulted.

A general rule for adding text to
a slide is to use not more than two fonts in a presentation and vary the font
size. Furthermore, to make a slide legible, in addition to the point size, attention must be paid to the word count per slide, the choice of typeface, and the visual
balance of space to text.
