Litmus Milk Procedural Essay Example for Free

Litmus Milk Procedural Essay Litmus milk is a complex medium that can potentially distinguish many species of bacteria. Litmus milk has several components that can be metabolized: lactose (milk sugar); casein (milk protein); and litmus (a pH indicator). If lactose is fermented, the solution should turn pink. If gas is produced during fermentation, you may be able to see bubbles or cracks in the milky medium. If lactose is not fermented and proteins are metabolized instead, the solution will become alkaline and turn blue in color. If casein is digested, the milk will coagulate to form a curd (a solid). Casein may be metabolized all the way down to individual amino acids. This process, called peptonization, results in a clear (not milky) liquid that is usually brown in color. Finally, the litmus may be reduced and become colorless. The culture will then look milk white. Materials: 1. Litmus Milk Broth 2. Bunsen Burner 3. Inoculation Loop 4. Nutrient slant 5. Goggles 6. Lab Coat 7. Incubator Procedure: 1. Get an Inoculation loop and sterilize it using the Bunsen burner. 2. Take bacteria from your nutrient slant on inoculation loop 3. Inoculate a litmus milk tube with the bacteria. 4. Incubate for 72 hours; observe results every 24 hours for 3 days.

The International Whaling Regime Essay -- Argumentative Persuasive Ess

The International Whaling Regime In his article, â€Å"Whale Mining, Whale Saving,† Sidney Holt states, â€Å"saving the whales is for millions of people a crucial test of their political ability to halt environmental destruction†(Holt 1985). In a world where environmental issues are often so vast that solving them seems impossible, it is rare to encounter a regime which successfully addresses these problems. If we judge a regime’s effectiveness by its ability to change the behavior of its members and possibly even encourage others to join, then the whaling regime was in fact quite effective. The significant decrease in commercial whaling brought about by the International Whaling Commission (IWC)’s 1982 moratorium is proof in itself of the whaling regime’s effectiveness. That being said, the history of the regime has not been without imperfections, and these shortcomings will continue to shape the successes and failures of the whaling regime in the future. While the peak of whaling in recorded history occurred in the 1930s where close to 55,000 whales were caught each year, whaling has been practiced by people for centuries and was unregulated for most of that time period (Andresen 2000). However, in 1946, the Convention for the Regulation of Whaling (composed of 15 nations including the U.S.) met and created the International Whaling Commission in order to address the problem of declining whale stocks. An increase in commercial whaling as well as introduction of â€Å"factory ships† which allowed whalers to travel far out to sea, catch whales (pelagic fishing), and process them on the boat without going back to shore had begun to put a strain on population numbers of certain whale species.

Stylistic Analysis : “a Cup of Tea” by K.Mansfield

Written by ASUMAN BIRDAL STYLISTIC ANALYSIS : â€Å"A CUP OF TEA† by K. Mansfield The common view that a literary text is likely to be comprehended better if it is studied in parallel with stylistic analysis which emphasizes the crucial role of the linguistic features of the text contributes much to the development of literary criticism. M. A. K. Halliday is one of the text linguists who sees ‘grammar’ as a network of systems of relationships which account for all the semantically relevant choices in language, which is the standpoint of the stylistic analysis as well. In the light of M. A. K. Halliday’s discipline, I will try to analyse a piece of literary text written by Katherina Mansfield in the format of a short story titled â€Å"A CUP OF TEA† and try to criticise the text objectively in relation to its grammatical (functional) features . Before this , I’d like to give a brief information about the content of the story. A. INFORMATION ABOUT THE STORY Scanning the story first, we come across with a rich couple named Rosemary and Philip leading an untroubled, desirable life and they seem to love each other since- we have no implication whether they love each other for money or not – and everything goes well in their lives. Rosemary spends money without getting into trouble and giving no reason or excuse to her husband in doing this. Everyone in a society admires Rosemary not maybe for her beauty but for her remarkable features such as being interested in current movements from every aspects, seeming as an intelligent young woman, reading the modern books. Philip is not as bright as Rosemary but he makes himself realize as soon as he enters the story towards the end. Apart from the couple, there is a girl who meets Rosemary in a street by asking for money to have a cup of tea then is picked up by her to have a cup of tea at her home and begins to be directed by her. We infer this from the fact that whenever Rosemary wants her to enter the scene she is there but when, at the last scene, Rosemary is jealous of her, the girl is easily disappearad without giving no sign for us to follow the reason of her disappearance. And we have one more character having a part in the story :the shopman. He is also under the effect of Rosemary; we can understand this from his polite behaviours which are made obvious in the text with circumstantial features. But he is the person also who utilizes by the weakness of her. He tries to draw her attraction on the enamel box and succeeds it; he promises her to keep the box for her because he knows her and he knows that she will come to buy it; she has the power of money and gets whatever she desires without acconting for anything to anybody. Not only we encounter with her weakness in her dialogue with the shopman but also in her being jealous of Miss Smith when he utters lovely words for this girl and behaves as it is predicted by Philip who knows directing her and makes her behave as he desires taking advantage of her faulty character successfully. In that sense Philip is an intelligent man and effective on Rosemary who is also obviously the symbol of possessive female by being jealous of the girl she has met in the street; so she has no self-confidence ,she is a little bit credulous. She asks directly-having no hidden meaning in her words- ‘Am I PRETTY? ’, which ironically reveals her ex-behaviours to Philip even she supposes that Philip is not aware of the truth. B. ANALYSIS When we look at the story from the point of ‘transitivity functions’ included in the stylistic analysis which tell us about the language and its reflection on processes ,participants ,circumstantial functions we realize that main participant is ‘ Rosemary’ and most of the processes are acted by her. When we count all the sentences describing her or the ones in which she takes place we realize her dominancy at once. The other participants I’d like to analyse on this text -apart from ‘Rosemary’- are the girl,Miss Smith, and Philip. Even though Philip hasn’t got as many turns as Rosemary and Miss Smith, I’d like to examine the processes of him in order to display the currents of events as a whole- he is the efficient figure in the sequences of events in the story-; in other words it is vital to handle it here to maintain the entirety of the text. To do this I will follow M. A. K. Halliday’s process in which ‘Ideational’, ‘Interpersonal’, ‘Textual’ Functions of language are daelt with in order to support all my commentations on Katherine Mansfield’s work.

The Results Of Depressive Symptoms - 1707 Words

The results showed depressive symptoms did not differ between the non-complicated bereavement group and the unbereaved control group, both groups displayed little to no depressive symptoms. Although the CG showed slightly higher ratings of depressive symptoms, the results showed only mild to moderate depressive symptoms were present on average in the CG group (O’Connor Arizmendi, 2014). These results demonstrate the participants who were suffering from CG were not suffering from MDD. Results from the Digit Span Backwards subtest and Wisconsin Card Sorting Task did not show any significant differences between the control group or the two bereaved groups (O’Connor Arizmendi, 2014). This indicates working memory and set shifting were not†¦show more content†¦Despite there results O’Connor and Arizmendi (2014) acknowledged their study must be replicated using a larger sample size to increase the study’s reliability. The authors also suggested an fMRI would be useful to measure what neurological processes are distinctly different in those suffering from CG. Nonetheless, their study and two previous studies have shown attentional biases are present and affect the cognitive functioning in individuals experiencing CG. Attachment-based Model Shear et al. (2007) focused their studies on an attachment-based model of complicated grief with an emphasis on the contribution of avoidance. The attachment-based model assumes the loss of an attachment figure causes an interruption in an individual’s attachment working model. Shear et al. (2007) references Bowlby’s theory of attachment, which stated at a young age a baby develops an attachment bond to their caregiver or loved one. Shear et al. (2007) reported Bowlby theorized, as a child ages the attachment relationship is translated into an internalized working model. This working model provides a secure base, which allows an individual to utilize his/her exploratory system to discover new experiences and attain certain goals (Shear et al., 2007). Shear et al. (2007) postulated the loss of a loved one disrupts this attachment working model which can lead to
