Chemical admixtures have become one of the essential components of concrete in recent years. Nowadays according to the needs of the users various chemical admixtures in different composition have been available in the market. The most commonly used for this purpose are those of plasticizers and superplasticizers which have the ability to increase the workability of concrete considerably. Superplasticizer has various applications in concrete like high volume fly ash concrete, superplasticized fiber reinforced concrete and shortcrete, high strength and high performance silica fume cement concrete, etc. Nowadays workability is one of the major issues of a freshly prepared concrete, which can be enhanced by superplasticizer. These superplasticizers will reduce the water-cement ratio and also improve the workability of concrete. Therefore, advanced concrete technology requires a detailed study of effects of superplasticizer upon the workability of concrete. The workability of concrete can be enhanced by using exact required amount of superplasticizer. A fresh concrete is desirable to be malleable or workable. But sometimes, desirable workability cannot be maintained due to scorching conditions at site. Then superplasticizers will lower the shear and flow resistance of concrete and enhances the workability to sufficient extent.
Currently available superplasticizing admixtures are micromolecular organic agents. These admixtures do not entrain a significant amount of air as they do

Comparison of three alternative bolus materials to Superflab in providing the maximum dose buildup (Dmax) Many superficial tumors are treated using 6 Megavoltage (MV) photons, but often require a bolus to bring the depth of maximum dose closer to the skin surface. A bolus may also be used to compensate for uneven skin surfaces or irregular contours in the patient. The depth of maximum equilibrium describes the depth in which the maximum dose of the formulated radiation is deposited (Washington & Leaver, 2010). Bolus material should be flexible, pliable, and tissue-equivalent.

One example of why Mk-Ultra is unethical is the damage that occured in a individual’s life. For instance, an unidentified woman and men articulated how the experiment “cost me my life” and that it was “like they had complete control over me” (Mind Experiments). Taking over a individual’s mind and physical body will never be humane, especially if it is at the expenses of another's life. Additionally, a more personal testimony was when Russell Kirk explained that he didn’t even know what he was doing and on several attempts he tried to commit suicide. He describes how he felt depressed but couldn’t understand why he felt so wrong.

Do you think Alice Thornton’s proposal to decentralize the rules and procedures of Cosmo Plastics will work? Alice proposal of decentralizing the rules and procedures in Cosmo Plastics has a bigger chance of working out in a big company with different departments and great number of employees, because then daily operations and decision-making are divided into different authorities in the organization from the top managements, to the middle and lower level managements. Especially when you have this flexibility in work hours, because some departments in the company need constant attention and discipline from the side of employees, decentralizing is needed to divide the controlling process. On another scale, small groups will be formed, employees
