Due to the complexity of these systems, rigorous models based ontheory are not available. Therefore, the empirical equation given by Merchuk is usually used todescribe binodal curves. However, Merchuk’s equations provide a poor extrapolation ability.Therefore, the aim of this work is the analysis of other equations, comparing the modelsreported in the literature and proposing alternative equations to improve accuracy or to reducethe mathematical complexity. The research objectives of this project are:i) To compile a database containing experimental data of solubility of nine aqueousbiphasic systems based on ethyl lactate;ii) To select statistical criteria to be used for the selection of models;iii) To fit various empirical models to experimental data;iv) To analyse and compare the effectiveness of empirical models, allowing discussion ofthe advantages and disadvantages of each equation.MS Excel will be used as calculation tools.

Once you enter “soil” in the search engine, you will see more specific categories to search if “soil” is too broad for youMake sure to use Google Scholar as your search engine so that it filters through peer-reviewed sources.Watch this video to get an idea of how to use Google Scholar.Select and summarize one or more of the studies.Make sure to maintain your citations (watch the video in 3b if you aren’t sure how to do this).Research peer reviewed studies that have been conducted on ONE of the soil characteristics that we will analyze in this experiment. You may choose from the following:Soil structureSoil pHSoil potassiumSoil phosphorusSoil nitrogenSelect and summarize one or more studies on the soil test you selected in step #4.Part 2: Developing your hypothesisWe calculated the relative density and relative frequency of five prairie plants in our first lab. Your hypothesis for this lab should be a possible explanation for that data (see figures 1 and 2 below) based on the soil tests we are conducting.Based on your research from part 1, #3 and #4 above, develop a hypothesis for the different relative density and frequency patterns between the two reconstructed prairies.Note: A hypothesis is a testable prediction, but we haven’t tested this yet, so you cannot be wrong!Feel free to use this format for your hypothesis if you aren’t sure how to write one.(insert on observation about the different density or frequency patterns between the two prairies) could be explained by (insert soil test), because . . .You could strengthen your hypothesis by including peer-reviewed studies on the soil requirements of one of the prairie plants.Part 3: Writing the introductionSummarize the purpose of investigating soil characteristics. (See Part 1, #1)Summary of current research/literature related to the topic. You should have at least TWO (2) outside sources cited. One should be about soil. The other should be about one of the tests that we are conducting in this lab.Use Google ScholarMust be from peer-reviewed journalsInclude internal citations following MLA formatHypothesis for the study you are conducting (not the ones you cited)Your hypothesis should be written in this format: (insert on observation about the different density or frequency patterns between the two prairies) could be explained by (insert soil test), because . . .Part 4: Finishing up the report.Click here to open up the template you are to use to finish the report, and finish writing all sections.Click here to view the rubric that will be used to score your report.Make sure to look at the feedback you received on your last report so that you know what you did well, and what you need to improve on in this lab report.This report is the reassessment of the last lab report, and therefore your grades on this report will replace the grades on the last lab report.

Choose one of the following two options to address in this discussion. Be sure that your initial post meets the full length requirement of 300 words, and that you incorporate at least two of this week’s required resources in your post, one of which should be the textbook. Include citations and a full reference to your chosen sources. (See the Required Resources page for all references in APA format). Option 1: Review the Corporate Anthropology: Michael Henderson at TEDxAuckland  (Links to an external site.)  video and read Body Ritual Among the Nacirema  (Links to an external site.) . Pretend that you are an anthropologist. Describe a typical day in the life of the Nacirema (remember that the Nacirema are Americans—Miner is describing us from an etic perspective). Describe your modern tribe (the people you spend most of your time with). What might someone from another culture find unusual about your daily routine, workplace (if relevant), and setting? How would a cultural outsider see your life? Is there anything she or he might find unusual or interesting that you see as normal and everyday? Option 2: Review the TED Talk Chimamanda Adichie: The Danger of a Single Story  (Links to an external site.) , then Briefly describe the stories that you grew up with, whether these are from books, TV shows, movies, or another source. How did these stories influence your perceptions of yourself and of the world? Did you identify with the background of the main characters or were they from a different background than you? As an adult, what stories do you identify with now? How are these stories similar to and different from the ones you grew up with? Are there certain areas of the world or certain people about whom you only have a single story? How could you work to broaden your understanding of others?

You have to cover up following things 1; epistemology of research and theoretical underpinning of article 2: research design 3: How well the chosen methodology addresses the questions posed in the articles 4What the articles tell you about human services research

Select a research topic according to your area of interest and Make a research proposal including general background, problem statement, objectives, types of research to be used, the sources of the data, and so forth. 

Give some reasons for our knowledge of the solar system has increased considerably in the past few years. Support your response with at least 3 reasons with details regarding concepts from the units learned in this course.

The letter of intent is a critical part of the application. It is the first writing sample an applicant submits to the faculty. Reviewers will consider both the content and writing skills of the letter of intent. Respond to each area listed below in paragraph format. The length of your letter of intent should be approximately 2-4 typed and double-spaced pages, not to exceed four. Your name should appear in the upper right-hand corner of each page. I. What is your understanding of the social work profession? II. Career Goals What interested you in pursuing social work as a profession? How did this interest develop? In what special fields of social work do you have an interest? If you trained for or worked in another field, why are you proposing to get a social work degree? III. Life Experiences Related to Social Work Social work requires working with people of diversified backgrounds with varied problems and the capacity for understanding and helping people. What experiences have you had in working with people of diversified backgrounds and how would these experiences help you work with people of diversified backgrounds? In what other ways have your experiences contributed to your interest in social work? Describe experiences in family relationships, group relationships, work, volunteer, recreational activities, etc., which you think affect your potential for social work. What are your strengths, as you perceive them, which you think will stand you in good stead as a social worker? What professional areas do you target for growth as you engage in social work? IV. Graduate School Readiness Graduate School is time-consuming and academically challenging. How do you plan to balance the demands of your personal life with the academic demands of graduate school? All MSW programs require experiential learning through field education courses that take place in an agency setting as an integral part of social work education. Due to the experiential nature and supervision requirements, field education courses will be completed in an agency setting during normal business hours to provide an opportunity to develop competencies in areas prescribed by the Council on Social Work Education educational standards (evenings and weekends are the exceptions). This is often challenging for part-time, online students or students trying to work full-time. Please describe your plan to be available to intern in the agency during normal business hours to ensure the field is a successful part of your educational experience.
