Fourastiér, where the principal urbanization functions are structured to: - primary Sector I (agriculture, hunting and forestry, mining and quarrying, fishing), - secondary Sector II (manufacturing, electricity, gas and water supply, construction), - tertiary Sector III (trade, repair activities, hotels and restaurants, transport and interconnections, the financial industry, public administration, education, the healthcare industry and social work, other community, social and personal services activities).
The creation and development of urban structures has been highlighted through the use of priorities, for example within the town – in the renewal of town centres, creating a substantial part of the workplaces of inhabitants and their interest territories, through the humanization of large dwelling units and location restructuring of their facility and professional structures.

An empirical mathematical models [7] describing the boiler steam temperature control object is shown in table 1 Table 1 Transfer function of main steam temperature due to spray-water disturbance under representative loads load Leading area Inert area 37% 50% 75% 100% When researching on closed-loop control system in situations of large scope or the whole change process, there exists shortcomings by using different points of multiple transfer functions as simulation objects, namely there need to switch models or test in step only, in which each controlled object remains linear and time-invariant at the same time.

Cotton also has a reputation as a water-intensive crop, and questions have been raised about the efficiency of water extracted for flood irrigation, water quality concerns such as pesticide run-off into groundwater, and water scarcity in relation to water availability.
Furthermore, consumers are highly sensitive to water and pesticide usage in cotton production [6].
One figure from the World Wildlife Fund (WWF) [38] states that it takes up to 2700 litres of water to produce a cotton t-shirt.
Another claim, from the Textile Exchange [39] report, suggested that organic cotton uses 91% less blue water consumption than conventional cotton.

Poly (vinyl alcohol) is one of the polymers of great importance in many applications, especially in commercial plastic uses, as it possesses a solubility in water.
As well as being soluble in water, slightly soluble in ethanol, however Insoluble in other organic solvents[9][10].
PVA it is an organic polymer and has a wide range of applications in the biochemistry, biomedical and pharmaceutical sectors, and the production sectors such as packaging due to its good compatibility with some substances, its ability to soluble in water and its relatively high ability to biodegrade in some environments, and it is considered one of the most studied materials for its use as an electrical insulating material and use in the applications , industrial , military, and space[11].
PVA polymer samples was dissolved for each sample in (15) mm of distilled water, and to ensure complete solubility of the polymer, a magnetic Heater Stirrer device from (LASSCO) brand of Indian origin was used.
