1.    (30 points) A student working in Dr. Selbys research lab orders a new lab buffer system from Sigma chemical company.  The chemical formula is proprietary and the manufacturer refuses to release the complete chemical formula.  From the companys technical data sheet, the following information was provided, the buffer system is a triprotic buffer system with each proton being attached to a unique functional group that equilibrates as shown in the reaction below Sigma also includes that A represents the polyatomic chemical species that Sigma chemical refuses to release;
H3A + H2O        H2A- + H3O+        HA-2 + H3O+          A-3 + H3O+
Its known that the A portion of the buffer has a molecular weight of 135.25 g/mol.  The four components of the buffer system are packaged separately as dry powders with one in the fully protonated form and the others in the three sodium salt f

For this assignment, you are asked to provide a review of the research and practice evidence on one of the following topics:

Risk factors and risk assessment in family violence
The effects of family violence on children and implications for practice
Multi-agency and collaborative practice models in response to family violence
Diversity, intersectionality and building inclusive responses to family violence
You will need to structure your Evidence Review just like you would an essay (e.g. with a title, introduction, clear paragraphs, conclusion and references), and make sure that it presents an overall argument.

you need to revise the draft first, then write the discussion.  Remember read the feedback carefully, the professor does not allow to use primary source,as well as survey data, he only allwo to use SECONDARAY DATA. This means you need to remove all survey data and primary data from the draft.

4-5 page limit is for content only; it does not include cover page, abstract, and references used in the assignment
Please reply to the following questions in your paper, and separate each one with major headings and subheadings as needed to present an organized APA paper. Your responses can be 1-3 sentences per question, and all sub-questions should be included.



1. Begin by discussing what the article is about. What are the research questions that are the basis for this study? What is the research hypothesis, if it is present. (There may be several, so state them all.) If there are not research questions and/or a hypothesis, indicate that is the case and provide your interpretation of what the research question and hypotheses are. Why is this article important and/or useful to healthcare professionals? (4%)

2. What is the sample used for this study? Is it a representative sample of the larger population? Is the size appropriate? Why or why not? (2%)

Base scenario:
Your company plans to purchase a new machine. Its purchase price is estimated at 500.000 . You plan to use the machine for 5 years. After that period you will be able to sell the used machine for 30.000 . During usage you have to bear costs for maintenance and repair that amount to 10.000 in the first year of usage and increase by 10.000 per year afterwards. Using that machine you could avoid purchasing components from external suppliers which currently cost 250.000 per year. You have calculated the NPV as shown in the following table.

Description of sub-tasks (weights might be different in actual THE!):
1. Calculation (40%)
You want to contrast NPV with another measure and decide to calculate the accounting rate of return for the investment. Make necessary assumptions to convert cash flow figures into cost and revenue figures and calculate the average accounting rate of return.

2. Interpretation/explanation (40%)
Is this an attractive inves

Most information is given, I just don't have time to complete it myself some issues turned up. There is a video link as well that corresponds to the assignment. If clicking the link doesn't work the name of it is "Flipping Physics A Brief Look at the Force of Drag using Numerical Modeling (or The Euler Method)". I don't expect perfection as the highest I've gotten on these labs were 90%.

Each page should be numbered and identified along with total number of pages. For example, pages 1 and 2 of an 8-page document would be identified 1/8, 2/8.
When answering the assessment, be mindful that this will be marked from a computer screen. Ensure your writing is as clear as possible
Do not answer the same question multiple times.

I send for you an example.
The homework starts Friday 6/19/2020 at 3.30 p.m. GMT+2 and it will take two hours, until 5.30 p.m. GMT +2. I put also correction of this example.
The homework will be similar.

Thanks in advance for your help..

Think back to publicity you have heard recently about a company or its products. If it was good publicity, how was it generated and what media were used? If it was bad publicity, where did you learn about it and how did the firm try to control or neutralize it? ONE PAGE EACH TOPIC, ONE REFERENCE

Food manufacturers often set up tables in supermarkets and offer free samples to shoppers, along with coupons for the promoted items. Sometimes restaurants offer free coffee or drink refills. What other products might lend themselves to sampling? Where and when would you sample? To whom would you offer samples?
