... reactions: 2C3S + 6H = C3S2H3 + 3CH 2C2S + 4H = C3S2H3 + CH During the initial stage of hydration, the parent compounds dissolve, and the dissolution of their chemical bonds generates a significant amount of heat. Then, for reasons that are not fully understood, hydration comes to a stop. This quiescent, or dormant, period is extremely important in the placement of concrete. Without a dormant period there would be no cement trucks, pouring would have to be done immediately upon mixing. Following the dormant period (which can last several hours), the cement begins to harden, as CH and C-S-H are produced. This is the cementitious material that ...
... not be consciously seen, but subconsciously absorbed (Lechnar 3). Vicary reported an increase in the sale of popcorn and Coca-Cola as a result of his subliminal messages. He was later questioned about his results. He had no evidence of his findings and admitted his results were false. This example brought the public’s attention to the power that advertisers held over them. To produce an effective advertisement, a company must invest a substantial amount of money to create a demand for their product. An ad agency can spend up to $50,000 to create a single, one page magazine layout or flyer containing subliminal messages, carefully reviewing it to attai ...
... dances dealt with the spirits of dead human beings. There was also a ghost dance to cure sicknesses caused by ghosts, and a ghost scalp dance. Among western Sioux in 1890, believers danced around a pole or tree decorated with sacred artifacts. The dancers wore special clothing called ghost shirts, which were painted with sacred symbols, including moons, stars, and eagles. The Sioux believed the shirts would protect them from anything, even enemy bullets. The Ghost Dance prospered in the Indian communities for nearly ten years. Then, in 1897, the Ghost Dance at Alisal was accompanied by a procession led by Chief Tarino to Mission San Jose's centennial annive ...
... Women, especially, are told that their efforts to exercise and to stay fit will be rewarded by success in their personal and professional lives. If they fail at the idea they are encouraged to try harder. The cruel thing is that the social requirement that we achieve the "ideal weight" is based on the presumption that we can completely control our body size, which is not true. The only things that seem to sell these days are young faces. It seems as if the younger the better. When you take a look at all the new television shows and movies all you see is young faces. It is harder for the older and more experienced actress to get roles nowadays. They are pairing up ...
... the airbag is usually too much for them. Never put a rear facing child seat in the front seat of the car. If the airbag goes off, the seat will be pushed forward and the child may get squeezed between the back of the seat and the airbag. Children are less likely to be killed in a crash if they are in the back seat. If someone must put a child in the front seat, they may want to have an on/off switch for the airbag installed on the passenger side. On/off switches are used to prevent the airbag from going off in an accident, but they aren’t recommended for most people. You only need an airbag switch on the driver’s side if your legs are too short to reach ...
... the writings of Plato. The skeptic, Boso, question's Anselm's faith with an array of questions non-believers still ask today. Anselm answers in a step- by-step manner, asking for confirmation along the way, until he arrives at a conclusion with which Boso is forced to agree. This is just like Socrates' procedure with, say, Crito. Later philosophers have both accepted and denied the validity of Anselm's famous ontological argument for the existence of God, presented in both the Proslogium and Monologium. Anselm did not first approach the argument with an open mind, then examine its components with a critical eye to see which side was best. Anselm had made up his ...
... could supply. (Moynihan 45) At this time, rumors spread among the plantation owners that Koreans were more industrious then either the Chinese or the Japanese. After consulting with the US ambassador to Korea, recruiters became journeying to the peninsulas. (Moynihan 45) The Hawaii Sugar Planters Association struck a deal with David Declare, who was paid five dollars for every laborer he lured to the Hawaiian Islands. (Moynihan 45) Deshler even offered unsuspecting Koreans loans of $100 so they could travel to Hawaii and get settled. (Moynihan 45) Despite their distrust of Western ways and people, Koreans of early 1900's found terms of migration attractive: a ...
... threat, hence he or she is subjected to forced inclinations by other members of society. For example, walking around nude on the streets of Cairo might be youre cup of tea, alas, in Cairo they prefer coffee. In other words, if you offend other individuals, you are in fact infringing on their rights as free citizens who poses a sovereign mind. However if you choose to remain nude while in the comfort of your hotel room in Cairo, then there is no reason why you shouldnt. According to Mill, education is a fundamental requirement for being an individual as well. But once again, there should be no forceful applications towards what is being ...
... done for reasons which are ultimately self-serving (p.43-47). For example, if I were to donate to charity, I am actually taking delight in demonstrating my power. Hobbes believes that any account of human action, including morality, must be consistent with the fact that we are all self-serving. His theory notes that humans are essentially equal, both mentally and physically, so that even the weakest person has the strength to kill the strongest (p.44). Given our equal standing, Hobbes believes that there are three natural causes of quarrel among people: competition for limited supplies of material possessions, distrust of one another, and glory so that people rema ...
... when a student graduates he or she is prepared to be a productive part of society. Besides just having a standard there must be some way to check that it is being followed. There are standards in place now that try and make sure that a student is learning what he or she needs to graduate. These are in the forms of test. The problem with these tests is that they are taken every few years. By this time a student may be so far behind and lack the skills necessary that it would take a miracle to have him or her master the essential skills. Another problem with this is finding out where they went wrong. The way these evaluations should be done is by looking at seve ...
