The Chemistry in Desalination Plants Research Paper

The Chemistry in Desalination Plants - Research Paper Example As the discussion declares there are various processes which are involved in desalination of water. Through the process of distillation liquids are separated from one another due to their difference in boiling points. The instrument used in distillation is called a ‘still’ and it consists of a pot, condenser, and a receiver. The liquid is heated in the pot, the condenser condenses it and the receiver receives the separated liquids. There are three different processes of distillation; Multi-Stage Flash, Multiple-Effect and Vapor Compression. In all these three processes water is either heated or passed through steam tubes and separated. This study highlights that an additional method is the process of Electro dialysis in which salt ions are transported from one solution to another by passing them through an ion exchange membrane. Due to the electric charges possessed by the ions they pass through the electro membrane. The membrane has the skill to select or reject the ions and transport them hence it is utilized in separation or removal of electrolytes. Another commonly used method in water desalination is the process of reverse osmosis. In this process the solvent is transported from a high concentration solution to a low concentration solution through a membrane. The membrane acts as a filter in which the solute is trapped on one side and the pure solvent is obtained on the other side. This method is used is obtaining fresh water from sea water. The pressure is applied on the higher concentration solution. The outwardly applied pressure builds up and is greater than the concentration difference hence the net solve nt movement is from high concentration area to low concentration area. Finally as the solute cannot pass through as the membrane because is it not permeable to it, the solute and the solvent are separated.

UNION BARISTAS AT STARBUCKS - Essay Example the National Labor Relations Act(NLRA).Thus, the NLRA clearly states that employees shall have the right to organize themselves, forming, joining, or assisting labor organizations so as to have a collective bargain through choosing their own representatives ,engaging in other intensive activities for the goal of collective bargains and it shall be unjust labor practice for an employer to impede, hold back or force workers in exercising of the guaranteed rights.

An employee is also entitled to signing a card or petition to showing support for a given union. Lastly an employee can request fellow workers to support the union, sign petitions or cards asking their employer to be aware of as well as bargaining with their union. On the other hand it is illegal for an employer to issue threats of or actually sacking, lying off, disciplining, harassing, transferring, or reassigning workers due to their supporting a union. In addition an employer should not show favoritism to workers who are ag ainst the union over those in support in such aspects as job assignments, promotions, hours, salaries, implementation of rules or any other working condition for that matter. It is also illegal for an employer to close the work station or remove any benefits or privileges workers already enjoy so as to dispirit presumed union activity. An employer should also not make promises to workers’ pay raise, promotion, benefit or unique favor for opposing

Comparative Method in Political Science - Essay Example Cultural trends and ideologies differences have also been cited as determining factors behind the association between GDP and democratic processes. The differences between democratic processes and authoritarian systems may relate to the inherent factors of organization, heritage and nature. According to some theoretical perspectives, the level of political participation is regulated by n interplay between external and internal processes, which in turn affects the nature of politics as they occur in different places. Discourses of the public sphere have emerged to affect the manner in which politics differ from one place to another or from one country to another. Some of the propositions that have been put forward to explain the relationship between GDP and politics are consistent with the modernization theory. Generally, the level of growth of GDP is considered to be a significant indicator of the relationship that happens between one country and another. Political processes are necessarily linked to economic systems and the cultural life of a people. In democratic processes, the system of governance is usually based on the tastes and preferences of the people. The citizenry determine the manner in which they want to be governed. Usually, the nature of politics will ultimately determine the level of economic development of any given country. The political environment is one of the major factors that determine the kind of economic activities in the country. It might be argued that political processes are naturally related to some of the issues that affect development processes. Politics forms the superstructure on which the systems of development are necessarily determined. In line with this kind of thinking, it might be argued that democratic processes are more likely to supply appropriate synergies for development that autocratic regimes. Indeed, studies have indicated that countries that allow sufficient
