Article + full reference must be handed into seminar leader during your scheduled seminar during the weeks of sept 28th & oct 3rd (5 marks = 4 for correct article & 1 for correct reference) Name up to 4 researchers and identify the lead/corresponding author. Write a short summary of the article. Put the article summary into your own words. Referencing - you must give the full reference for your article at the end of your paper.

Dieting is common in our society and everyone wants a piece of the action. So many diets are available to choose from if someone wants to change their health; e.g., lose weight. Often times, diets are promoted with claims of great success.

For the purposes of this assignment, you are to choose a particular diet and analyze it in terms of scientific evidence, or lack thereof. Then, you are to design a controlled experiment to test a hypothesis based on this diet. The experiment must include multiple individuals within a control and experimental group. You must specify how you will measure the outcome of the experiment identifying both the independent and dependent variables. You must describe the potential outcomes of the experiment in terms of supporting the hypothesis.

Hi. You should write a Java program to meet the specification shown below.

In this game(dice poker), the computer rolls two standard six-sided dice and you bet on the outcome. The outcome is the configuration of the numbers rolled (explanation below). The input/output should utilise a graphical user interface (input and message boxes).

1.1 Game flow

You start with some money in your bank. You play a number of rounds, where for each round you place a bet and the computer rolls the dice, checks results and modifies your bank balance. After certain conditions, the game ends and you're presented with some final information shown as a message box.

1.2 Placing bets

Before the computer rolls the dice, you can bet some money from your bank.

ˆ If the numbers are sequential (e.g. 1 and 2, 5 and 4, etc. Not 6 and 1), you earn double your bet.

ˆ If the numbers are identical (rolling doubles), you earn triple your bet.

ˆ Otherwise, you win nothing therefore you lose the amount of money you bet.

Before placing a bet, the computer should inform you of your current bank balance.

1.3 Starting Game- Game rules

When the game starts you are given £6 in your bank. Each bet costs £1 and you are allowed to make up to five bets before the game ends. The game will end if you run out of money, or you have no more attempts left (you made all five bets). At the end of the game, you will be told which of these conditions has ended the game.

1.4 Results display

Once the game has finished (all bets have been placed or you ran out of money) the computer will collate and display the results in a single message box, comprised by:

ˆ On row per bet, displaying your bet, the numbers rolled, the amount of money earned or lost for that bet.

ˆ One row at the end, displaying the amount of money that you have remaining in your bank at the end of the game.

1.5..Variable bet amount

Allow the user to change how much they would like to bet and change the amount you win accordingly. Allow bets between £1 and 4£ (integers only)

1.6.High score table

Create a high score table. The more money you have remaining in your bank at the end of the game the higher up the table you will be. In order to implement this, players will have to enter their name before they play. The high score table should be displayed as a separate message box after the results have been displayed at the end of the game(1.4)

Not1: Please use JoptionPane class instead of scanner class.

Not2: Also If possible explain the description of your classes: what each does and how they relate to each other. And if possible, program should be extensible. E.g. Is it easy to change the number of dice? The number of rounds to play? The sides of the dice?Etc.

1. T F Broken glassware should be swept up immediately and placed in the garbage bin.
2. T F Eyeglasses or contact lenses are an acceptable substitute for googles during an experiment.
3. T F If you arrive at class to find a spilled liquid on your desk, you should assume it is water and wipe
it up with paper towels.
4. T F Students with long hair must tie it back when using Bunsen burners.
5. T F If you take too much of the chemicals needed for an experiment, put it back into the container you

13. T F It is ok to take off my safety goggles if it’s just for a second while I write something down.
14. T F If any chemical makes contact with your eye, wash it immediately at the eyewash station for
fifteen minutes. If you should spill chemicals on your skin, place the affected area under water
immediately.
15. T F Always read through each activity before you begin.

yourself. Asking the teacher for clarification will result in a lower mark due to lack of preparation.

22. T F Determine whether your equipment is cool enough to disassemble by placing the back of your
hand near it.
23. T F Loose-fitting, long-sleeved shirts should be worn during experiments to protect your arms from
burns and chemical splashes.
24. T F If you must retrieve materials during a lab, it is acceptable to leave your Bunsen burner unattended
as long as it is set to a yellow flame.
25. T F To avoid an injury when heating materials, always place a stopper or tight-fitting lid on the
container being heated.
26. T F If a student uses the last of the chemicals in an experiment, it is their responsibility to go into the

27. T F Always leave your work area clean and dry before leaving the lab and make sure equipment and
glassware is returned clean to its proper place.
28. T F Horseplay is O.K. during a lab as long as no one is getting hurt.
