Their Eyes Were Watching God In Their Eyes Were Watching God, Janie battles to find Individualism within herself. Janie, all her life, had been pushed around and told what to do and how to live her life. She searched and searched high and low to find a peace that makes her whole and makes her feel like a complete person. To make her feel like she is in fact an individual and that she's not like everyone else around her. During the time of ?Their Eyes', the correct way to treat women was to show them who was in charge and who was inferior. Men were looked to as the superior being, the one who women were supposed to look up to and serve. Especially in the fact that Janie was an African American women during these oppressed times. Throughout this book, it looks as though Janie makes many mistakes in trying to find who she really is, and achieving the respect that she deserves. Living with her Grandmother and theWashburns', Janie was surrounded and raised with white children. She always believed that she was white herself, and that she was no different than anybody else. As she was growing up, she was told what to do and how to live by her grandmother. Janie's grandmother planned her life out for her. She told her that she must get married right away. "Yeah, Janie, youse got yo' womanhood on yuh. So Ah mout ez well tell yuh whut Ah been savin' up for uh spell. Ah wants to see you married right away." Janie's grandmother did want what was best for Janie, but she basically told her what to do instead of letting her know what she wanted for her. Janie's grandmother told her exactly who she was going to marry and who she wasn't even to think about. "Whut Ah seen just now is plenty for me, honey, Ah don't want no trashy negro, no breath-and-britches, lak Johnny Taylor usin' yo' body to wipe his foots on. Brother Logan Killicks, he's a good man.......You answer me when Ah speak. Don't you set dere poutin' wid me after all Ah done went through for you!" She is basically telling Janie that she can't marry Johnny Taylor, the one she is exploring her womanhood with, the one she wants, and that she must marry Logan, for protection. Towards the end of the book, Janie resents her grandmother for "living" her life for her and planning her future. To find out what will happen in a persons future, they need to live their life on their own and not have it planned for them. They can't be told how to live there lives in order to succeed. To succeed, we need to learn from our own mistakes, and live with the weight of our decisions. This is exactly what Janie did in her marriage to Logan. She did as she was told, or rather, expected to do. Janie didn't want to marry Logan, but if it made her grandmother happy, then by all means, why not give it a shot. If it meant that she'd be secure. In her marriage to Logan, she found out that that's not what she wanted. Janie wanted love, happieness, comfort and enjoyment. She didn't want her first marriage to be like a prison sentence. "Did marriage end the cosmic loneliness of the unmated, did it compel love like the sun the day?" This is asking if marriage made love for Janie as the sun makes the day for the world. Is the basis of love marriage...just as the basis for day is the sun. To Janie, this was not true. She did not feel as though she loved Logan, and that's all she really wanted. She didn't want to be treated as the rest of the world was treated. She wanted to be treated as an individual and not as a slave. She was a slave to marriage. She didn't want to be there, where there was no warmth. Joe Starks stole Janie away from Logan. He saved her from the boringness of their dull marriage. He woed her with his words of kindness. He promised her happieness. "De day you puts yo' hand in mine, Ah wouldn't let de sun go down on us single. You ain't never knowed what it was to be treated lak a lady and Ah wants to be de one tuh show yuh." He wanted her to feel special, and be treated

Filtration Definition and Processes (Chemistry)

Filtration Definition and Processes (Chemistry) Filtration is a process used to separate solids from liquids or gases using a filter medium that allows the fluid to pass through but not the solid. The term filtration applies whether the filter is mechanical, biological, or physical. The fluid that passes through the filter is called the filtrate. The filter medium may be a surface filter, which is a solid that traps solid particles, or a depth filter, which is a bed of material that traps the solid. Filtration is typically an imperfect process. Some fluid remains on the feed side of the filter or embedded in the filter media and some small solid particulates find their way through the filter. As a chemistry and engineering technique, there is always some lost product, whether its the liquid or solid being collected. Examples of Filtration While filtration is an important separation technique in a laboratory, its also common in everyday life. Brewing coffee involves passing hot water through the ground coffee and a filter. The liquid coffee is the filtrate. Steeping tea is much the same, whether you use a tea bag (paper filter) or tea ball (usually, a metal filter).The kidneys are an example of a biological filter. Blood is filtered by the glomerulus. Essential molecules are reabsorbed back into the blood.Air conditioners and many vacuum cleaners use HEPA filters to remove dust and pollen from the air.Many aquariums use filters containing fibers that capture particulates.Belt filters recover precious metals during mining.Water in an aquifer is relatively pure because it has been filtered through sand and permeable rock in the ground. Filtration Methods There are different types of filtration. Which method is used depends largely on whether the solid is a particulate (suspended) or dissolved in the fluid. General Filtration: The most basic form of filtration is using gravity to filter a mixture. The mixture is poured from above onto a filter medium  (e.g., filter paper) and gravity pulls the liquid down. The solid is left on the filter, while the liquid flows below it.Vacuum Filtration: A  Bà ¼chner flask and hose are used to create a vacuum to suck the fluid through the filter (usually with the aid of gravity). This greatly speeds the separation and can be used to dry the solid. A related technique uses a pump to form a pressure difference on both sides of the filter. Pump filters do not need to be vertical because gravity is not the source of the pressure difference on the sides of the filter.Cold Filtration: Cold filtration is used to quickly cool a solution, prompting the formation of small crystals. This is a method used when the solid is initially dissolved. A common method is to place the container with the solution in an ice bath prior to filtration.Hot Filtration: In hot filtration, the solution, filter, and funnel are heated to minimize crystal formation during filtration. Stemless funnels are useful because there is less surface area for crystal growth. This method is used when crystals would clog the funnel or prevent crystallization of the second component in a mixture. Sometimes filter aids are used to improve flow through a filter. Examples of filter aids are silica, diatomaceous earth, perlite, and cellulose. Filter aids may be placed on the filter prior to filtration or mixed with the liquid. The aids can help prevent the filter from clogging and can increase the porosity of the cake or feed into the filter. Filtration vs. Sieving A related separation technique is sieving. Sieving refers to use of a single mesh or perforated layer to retain large particles​ while allowing the passage of smaller ones. In contrast, during filtration, the filter is a lattice or has multiple layers. Fluids follow channels in the medium to pass through a filter. Alternatives to Filtration There are more effective separation methods than filtration for some applications. For example, for very small samples in which its important to collect the filtrate, the filter medium may soak up too much of the fluid. In other cases, too much of the solid can become trapped in the filter medium. Two other processes that can be used to separate solids from fluids are decantation and centrifugation. Centrifugation involves spinning a sample, which forces the heavier solid to the bottom of a container. In decantation, the fluid is siphoned or poured off of the solid after it has fallen out of solution. Decantation can be used following centrifugation or on its own.
