<u>Operational planning</u> is planning done by first-line managers to determine how to accomplish specific tasks with available resources within the next 1 to 52 weeks.
A <u>procedure</u> is a standing plan that outlines the response to particular problems or circumstances.
<u>Explanation</u>:
An operating plan is a plan prepared by a manager which helps him to achieve his long-term target or goal in short time.
The first-line managers define some ways and plan to achieve the task with the available resources in next 1-52 weeks. This is known as <u>operational planning</u>.
A <u>procedure</u> is an official way of doing something. It helps in making a standing plan that summarizes the response to particular problems or situations.
Porosity is a cavity-like discontinuity and occurs due to the entrapment of gases in the molten weld pool. These entrapped gases don't get a chance to escape from the molten weld pool and hence cause porosity.
<h3>Which discontinuities are caused during welding?</h3>
Weld discontinuities can be defined as "an interruption of the typical structure of a weld, such as a lack of homogeneity in the mechanical, metallurgical or physical characteristics of the weld." Porosity is considered to be the most critical discontinuity. Weld discontinuities include porosity, incomplete fusion, excessive melt.

Thank you for posting your question here. It can be considered to be consistent with the given facts. As you know, an hypothesis, much less a theory, is never proven. It can be shown to be consistent with given observations. As new observations are collected, the given hypothesis may have to be modified.
If the celery became crisp when it was soaked in ice water, then clearly that the water has rehydrated the celery is a reasonable hypothesis. But did it have to be ice cold water? Would room temperature water work? What about boiling water?
And thus most of the time, the success of an hypothesis leads to the design of new experiments to test and expand the original hypothesis.
B. by a charter hope this helps good luck
