Determining Properties of Pero essays Determining Properties of Peroxidase Enzyme Jeremy Jones and 2:00 Tues. 1406 lab classmates Biology Department, Tarrant County College, Fort Normal function of peroxidase enzyme is to convert hydrogen peroxide to into water and oxygen. Experiments were carried out to check peroxidase activity at different concentration levels, pH levels, temperatures, and check effect of boiling and Peroxidase is a large protein containing hundreds of amino acids and has an iron ion located at its active site. It is easy to obtain and work with, making it an ideal candidate for lab work. The peroxidase reaction can be measured by following the increased oxygen levels. The simplest way to measure oxygen levels is to test with a dye that reacts to chemically active oxygen. The dye will turn from colorless to colored in a dye-coupled reaction. Guaiacol is a dye that turns brown when oxidized. The enzyme, substrate, and dye can be mixed together and immediately placed in a spectrophotometer. The absorbance at 500nm will increase as more color accumulates. Hypotheses: 1. More peroxidase activity will be observed at higher levels of concentration. 2. More peroxidase activity will be observed at mid-level temperatures and mid-pH levels. 3.Boiling will cause complete denaturation of 4. Hydroxylamine will inhibit all peroxidase activity. All experiments carried out as per Biological Investigations, 6th Edition by Warren D. Dolphin. See Lab Topic 6, Determining the Properties of an Enzyme. 1.

Potential 2020 Republican Presidential Candidates

Potential 2020 Republican Presidential Candidates President Donald Trumps surprise win in 2016 was good news for many in the Republican Party. But the outsider non-politicians win did not make all conservative members of the GOP happy. Some preferred a standard-bearer for the party who fit a more traditional mold than the outspoken New York real estate developer and reality TV star. Others saw him as someone who doesnt actually hold the conservative values he espoused. Three Republicans already have indicated their interest in challenging Trump in the 2020 primary season, and pundits speculate that at least one more might join the race. Bill Weld Former Massachusetts Gov. Bill Welds last run for office was as vice president on the Libertarian Party ticket, but the former Massachusetts governor re-joined the Republican Party to officially challenge President Trump in April 2019. Despite Trumps 90 percent approval rating among GOP voters, Weld insisted in a CNN interview that he can beat the sitting president. His strategy includes getting on the ballot in states that allow for crossover voting, meaning that people who traditionally vote for Democrats are allowed to vote in the Republican primary. Larry Hogan Maryland Gov. Larry Hogan is a moderate Republican who has said he would consider running against Trump in 2020 only if he thought he had a reasonable chance of winning. But polling even in his home state has shown that while Marylanders love him as their governor, Republicans favor Trump in a 2020 primary contest 68 percent to 24 percent. Hogan announced in June 1, 2019 he would not run, saying he would instead lead an advocacy group called An America United. John Kasich Former Ohio Gov. John Kasich already challenged Trump once, in the 2016 primaries, and came up short. The former Ohio governor was tenacious nonetheless and stayed in the fight until the bitter end. Kasich has continued his criticisms of the president as a cable news commentator. He  was rumored to be considering a 2020 campaign, but on May 31, 2019, he announced that he will not run, telling CNN, There is no path right now for me. I dont see a way to get there. Justin Amash Rep. Justin Amash of Michigan is a vocal Trump critic in the U.S. House of Representatives and began being talked about as a challenger to the president after he was the lone Republican in the House to join Democrats in calling for Trumps impeachment in May 2019. But the speculation was not over whether Amash would challenge Trump in the GOP primary. Instead, observers wondered whether the libertarian-minded Amash might indeed jump to the Libertarian party where he might steal enough electoral votes to be a spoiler in the general election. Others Other more conservative Republicans are not interested in challenging a sitting president, either because they support his policies or because they dont want to hurt their own political futures. Those likely waiting for the 2024 election include names like Vice President Mike Pence, Sen. Marco Rubio of Florida, Sen. Ted Cruz of Texas, former U.N. Ambassador Nikki Haley, Sen. Rand Paul of Kentucky, former Wisconsin Gov. Scott Walker, or even former Alaska Gov. Sarah Palin.

Free Essays on Kubla Khan Free Essays on Kubla Khan The Search For An Understanding â€Å"Kubla Khan,† a poem by the English poet, critic, and philosopher Samuel Coleridge, is thought to be based on an opium-induced dream. Coleridge supposedly awoke from his drug-influenced sleep and began to compose what was to become a well-known piece. He was distracted; however, while jotting down the lines he had in mind by a knock at his door. When he returned to his work, he was unable to remember the remainder of his thoughts and was forced to create the closing of the poem. The poem is lyrical in tone, resembling a meditative poem or an ode. Coleridge composed â€Å"Kubla Khan† somewhere between 1797-1798 during what is known as the Romantic period, but did not have it published until 1826 when his colleague urged its publication. Due to the opium Coleridge had allegedly been taking, critics are unable to establish one true meaning of the work. Much controversy surrounds the â€Å"Kubla Khan† and the issues of its wholeness; however, most critics agree that although it is written as a fragment, the piece as a whole is complete in meaning. One widely accepted analysis states that the â€Å"Kubla Khan† is nothing more than a fragment. It is known that Coleridge never wrote a piece that had any substantial length except for the â€Å"Rime of the Ancient Mariner,† which could be taken to mean that he was unable to complete a work. Coleridge himself initially subtitled the poem â€Å"A Vision in a Dream: A Fragment,† which further instates the poem as being incomplete (Mahony 2). There is a significant difference between the dreamed up words and the phrases used to finish the poem after being disrupted by a business man from Porlock (3). The poem’s preface gives Coleridge’s explanation of his reasons for publishing the poem as a fragment. Elisabeth Schneider states that, â€Å"The last eighteen lines are the poet’s explanation of his failure to complete the poem† (193). The last lin...

Nurses cannot achieve all of this attributes unless they have a good philosophy that guides them. It is good to appreciate the efforts put in place by room 4 moms. â€Å"Thank you for the efforts that you have put in place to offer the best services to your patients.† Jean Watson in his notes about human caring highlights some factors that can help one in caring for their patients. This factors are; ‘formation of humanistic-altruistic system of value, instillation of faith-hope, cultivation of sensitivity to one’s self and to others, development of a help and trust, human caring relationship, promotion and acceptance of the expression of positive attitude, neg ative feelings, systematic use of a creative problem and solving caring process, promotion of transpersonal teaching and learning, provision for a supportive, protective, or corrective mental, Physical, societal, and spiritual environment, assistance with gratification of human needs and allowance for existential-phenomenological-spiritual forces’. With all this in place then nursing becomes more philosophical, ethical and intellectually outlined. The room 4 moms come in with the issue of involving one's family in their nursing fields. This gives both the patient and the nurse to have a caring moment with each other. They both come together and share their unique life histories. The coming together at any given moment becomes an inclination point in space and time. During this time, experience and perception take place, but the moment shared together has a significant impact on the patient. They feel encouraged, and they feel both loved and wanted in the society rather than c onsidering them as the liability. The mom`s in rooms 4 believes in Watson`s theory about human caring. Watson at one point in his theory names ‘caring or healing for consciousnesses.

Habermas the Public Sphere Essay Example | Topics and Well Written Essays - 1000 words

Habermas the Public Sphere - Essay Example 1-13). According to many political theorists, the public sphere is an important entity for a strong democracy. The public and the private spheres acquired a clear distinction in the 17th and 18th century. The public sphere usually consists of informal citizen discussions and deliberations that lead to the formation of a public opinion which is rational enough to guide and influence political systems. Habermas has given a complete outline of the public sphere in The Structural Transformation of the Public Sphere: An Inquiry into a Category of Bourgeois Society. (1989). This piece of work outlines the public sphere critical theory in a systematically developed manner (Dahlgren, 1995, p. 44). The public sphere thus develops from the realms of public authority as well as private relations. The private relations may involve the family and the civil society at large. The private individuals, therefore, come together to form the public sphere. They are driven by the notion of speech without censorship as well as the desire for unified reasoning. According to Habermas, therefore, the public sphere involves both historical economic and political concerns. He continues to explain that every communication contains a communicative action which is oriented towards an agreement. Whenever a matter concerning living together as a people with differences is debated, the public sphere is always constituted. The public sphere became more of a commercial and entertainment entity rather than its conserving its political character. The shift from the original character to other commercialized versions is documented in the press. Habermas, therefore, looks at the integration of literature and journalism as well as the role played by mass media. The public sphere was also affected by the emergence of mass media. The apparent evolution of the communications environment has made the public sphere to change to a platform for advertisements. As a result of these, there emerges a new class of participants such as public relations practitioners (Thompson, 1993, p. 67). Democracy, according to Habermas, is founded on the world of life. It is this world of life that enables free communication between different people. It also drives people into pursuing private and individual interests as opposed to common goals in life. The media plays a crucial role in any democracy. This comes easier, of course, if the environment is right. Such an environment is one which consists of the requisite skills that enable democratic reporting. The media is most of the time flooded with advertisements that target some individual tastes. The information that is presented is also based on the pre-existing views. There should, therefore, be mechanisms which check for public accountability as well as professionalism in media operations. One of the characteristics that identify a democracy is the independence of the media. This is strengthened by the financial viability of the media organizatio ns. Financial strength ensures that the media operates in an environment free of external influences, especially political influences (Hallin, 1994, p.12). The media is also an essential for checking the political system when that system is unable to meet the social expectations. The media is, however, not expected to entertain political bias or partisan reporting at all. Accessibility of the media
