Act of turning around an axis
The term Rotation refers to the action and result of rotating, that is, turning around an axis. Rotation is a movement basically of change of orientation, so that given any point of the same it will remain at a constant distance from the axis of rotation.
Typical movement of the planet earth and that marks the beginning of day and night
Furthermore, Rotation turns out to be one of the movements made by the EarthBecause the aforementioned planet, being an ellipsoid body flattened by the poles, performs four main movements: translation, nutation, precession and the aforementioned rotation.
With respect to the rotation of the earth, it is the movement that rotate on itself along the earth's axis, imaginary this one of course, that passes through the poles.
A complete revolution of the earth if the sun is taken as a reference takes 24 hours. The solar day therefore has 24 hours, while if the stars are taken as a parameter, the complete turn lasts 23 hours, 56 minutes and 4 seconds. The difference appears from the advancement of the earth in its orbit.
The rotation of the earth with its proximity to the sun is what determines the day and night. That region of planet earth that faces the sun will be the one that will have day, while the other part, that is, in the rest of the world it will be night, not receiving sunlight until the rotation.
The ecliptic is that curved line by which the sun seems to rotate in its apparent movement from the earth. The obliquity of this line is the angle of 23.5 that the earth's axis makes with respect to the normal of the line. This inclination is what causes at the poles there are long months of light and dark depending on the incidence of solar rays.
Alternation of something
Another meaning of the word is that which refers alternation or variation of any issue. "A rotation in the positions began that will last until the end of the month according to the directives of the new manager”.
Staff turnover
So it is possible as we demonstrate with the previous example that we talk about job rotation, personal, that by Diverse needs of the companies change area or sector or there may also be rotation in terms of shifts and working hours. job.
Those companies that offer customer care services client 24 hours a day to attend to the claims of any type of its clients, for example those that supply InternetThey have a staff that answers these calls and that is organized in different shifts and days in order to respond effectively to the demand. Meanwhile, it may happen that due to a specific situation, the shift rotation of an employee is decided.
Now, we must say that staff turnover is not always looked upon favorably and produces positive results in the company that is practiced. In principle, a company that causes constant staff turnover, either due to layoffs or because they resign, tends to generate mistrust towards the company. This situation also threatens the bond that the employee has with the company and that is important for him to do his best for success.
It is only seen with good eyes when the turnover is the result of hiring more qualified personnel and the consequence of an injection of investment.
Crop rotation
Crop rotation It is the variety of alternative plantings, or failing that simultaneously, that are implemented to prevent the land from running out in the exclusive feeding of a single plant species and also with the mission of avoiding pests and ensuring better care of the soil.
Among the various variants that are proposed for crop rotation, we can highlight that of supplanting the sowing of cereals by that of legumes. In other words, the idea is that the alternating crops do not belong to the same familybotany than above.
Experts advise that if, for example, vegetables are planted that demand a lot of requirements nutritionally, once the harvest is over and harvested, the ideal is to replace the proposal for give him air to the land in question and for example plant legumes that will enrich the land by fixing nitrogen.
