The pH of different liquids before and after they are filtered Problem Does filtering different liquids cause the pH to change? Hypothesis: The pH of the dirty water and the salt/bicarb soda/sugar water will change the most drastically when they are filtered. Aim: To investigate the effectiveness of a natural water filter on the pH of different liquids. Materials: • Green Science Clean Water Kit (includes plastic filter system, active carbon, sand, rocks, and filter paper) • pH Indicator
repetition of a number we can detect different variations playing in our favor. Among them we have: 1. What numbers repeat and how often? 2. In which sequence do the numbers repeat: even-odd prime-even odd-prime. 3. If the digits repeat in a series of steps: for example advancing positions from a point to another like in this series: 01-44-45 23-01-34 33-41-01. Once we know the numbers that repeat the frequency and sequences we can choose them as part of your combinations and significantly increase your
relatively rare disease, new research discoveries show that it’s actually more common than not; while the onset of symptoms typically occurs in a person’s 40s and 50s, research has also shown that individuals in their 70s, 80s and even 90s have enough repeats in the HTT gene to develop mild HD symptoms. (Samson, 2016) Through the selective degeneration of neurons and with the loss of neurons from the striatum and cerebral cortex, Huntington’s disease affects the nervous system by impacting movement, cognitive
As once said by George Santayana,“Those who cannot remember the past are condemned to repeat it”(Flamm). One hundred years after the Emancipation Proclamation the Black Civil Rights movement started. During this time, African Americans had an unequal world of oppression and segregation. In 2013, the Black Lives Matter movement began. Some of their guiding principles are diversity, empathy, and collective value. Black Lives Matter is a very similar organization to Black Civil Rights. If America already
• I would say that Webern uses minimalism, a regular symphony takes so long, and repeats previous material sometimes to nausea (just my opinion), but Webern gives you all that you need and lets you fill in the gaps mentally. Schoenberg uses a lot of layering, multiple different melodies and rhythms going on at the same time, this happens after the initial cannon where the different instrumental parts repeat the same motive, most of the piece revolves around that (0,1,4) set class. • A simple
In our poem “Dear America, the Land of the Free” and other writings and speeches, rhetoric helps to powerfully convey a message to an audience. The more powerful the argument is, the more likely the audience is to spread the message to others and attempt to make changes in support of the message. The most effective literature and speeches are strewn with various rhetorical devices, as these devices cause the message to become clearer and more powerful. We see authors using rhetorical techniques to
there have been reduced repeat offences. Discussion Board The application of technology in forensics has been one of the major developments in forensics. This is because the technology has enhanced the quality of evidence collected trough increased credibility and reliability. The DNA databases have for example enhanced the manner in which investigators connect crimes with perpetrators. In addition, the database has made it easier to develop a connection between repeat offenders in the application
have used different methodologies to calculate the financial returns on art investments, based on public auction records. 2.1.1 General Review There are four main methodologies for producing art price indices. Average prices, geometric means, repeat sales and hedonic regressions. The first significant study was by Stein (1977), who analyzes the financial return of auctioned paintings in USA and Britain for the period of 1946-68 by using the average prices methods. Stein considered the auctioned
When dealing with other types of evidence such as hairs and fibers, tool marks, video footage, or even a weapon used at a crime scene; it can be challenging connecting the evidence to the suspect or even coming up with a suspect. These forms of evidence have been allowed in court in many cases and have also convicted many innocent people. Years later, their cases have been re-opened with new DNA evidence and have set the innocent free. According to the Innocence Project, Randolf Arledge was accused
For example, “round about” (Nash 7), “around” (11), and “again” (20). Ogden Nash includes this repetition to convey that time repeats itself. Never ending time keeps occurring. Each and every day is just like the day before. Each morning one wakes up, once again. By repeating words that have to do with the repetition of time, it gets in the reader´s head that time repeats itself. Nash also uses rhyme to convey the theme of time. Some examples are, “Past” (3), “vast” (4), “ring around” (11), “swing
