Meetings between the supervisor and the student Preliminary meetings Before a student begins researching and writing a thesis, the supervisor and the student should have a detailed discussion of expectations and requirements. Below are examples of general and specific issues to be discussed during the preliminary meetings with the potential supervisor.

As the tannins produce hydrogen peroxide the colour changes and then the peroxide changes the ethanol to ethanal and then on to acetic acid. The colour will change, the smell will be different, the ethanol decreases, the titratable acidity will increase.

Maybe worth checking out. For teachers who would like to have a basic introduction to wine chemistry or would like to have a refresher, the Queensland College of Wine Tourism at Stanthorpe offers a professional development workshop that may be useful.

No recommendations are made as it is up to teachers to check it out but reports have been good. No recommendations are made here but more information is available for download or on their website. Ginger Beer - avoiding the headaches Investigating the production of alcohol in wine can give you a few headaches - particularly if you think someone will drink your experiment.

Ginger beer is made traditionally by the yeast fermentation of a mix of sugar, water and ginger.

It is rarely produced commercially but often home brewed. The beverage produced industrially is generally not brewed fermentedbut carbonated with pressurized carbon dioxide. It is really just a soft drink, sweetened with sugar or artificial sweeteners.

However, there are some manufacturers who still brew it the old way: It is cloudy and if you hold the bottle up to the light and you'll see it's full of ginger pieces. Bundaberg Brewing uses the real ginger 'bug' plant.

Brew up some batches in the school lab - but don't drink it. The suspended yeast makes it look cloudy. Gary suggests this for his Year 12 EEI: You will be following a 'standard' procedure for making a simple beer e. This section of the work will also require you to define which factors you can reasonably test in a school-laboratory, and which variables in the production that you can vary.

A copy of the EEI task sheet is available for download here. You need a fridge and an incubator to give you three temps including room temp for the temp-as-variable".

His method is one of many that can be easily obtained from the internet: You need to create what is called a Ginger Beer Plant. Put 15g of general purpose dried yeast into a large jar or bowl, add mL water, 2 teaspoons ground ginger and 2 teaspoons sugar. Cover with a sheet of cling film and secure with a rubber band.

Each day, for seven days, add 1 teaspoon of ginger and 1 teaspoon of sugar to the mixture in the jar. Now strain the mixture through a piece of fine muslin and add the juice of two lemons to the liquid.

Add 50g or sugar to the liquid and make up to 4. Bottle into a plastic bottle Keep for days when the ginger beer is sparkling and ready for drinking. You can keep the sediment that you have left after straining the ginger beer plant.

Divide into two jars and give 1 plant away to a friend with the instructions. To the sediment add mL water, 2 teaspoons sugar and 2 teaspoons ginger and carry on as before. Also, most fermented soft drinks are acidified to inhibit bacterial growth. Does this also inhibit the yeast?

You could investigate the effect of pH on the rate of fermentation using lemon juice or better - citric acid. The juice of 1 lemon contains about 12 g citic acid. Be warned - you should not be drinking the ginger beer unless you have approval from your teacher and this is unlikely. Lastly, what sort of yeast is best?

I asked at my local brew shop and the guy said none was available in Australia and it had to be bought online.Jul 15,  · Average dissertation and thesis length, take two How long should your thesis be? | From experience to meaning juliagiddy says: My advisor once told me about a thesis that was three pages long.

Some guy/gal in analytical chemistry had worked a few years to develop some molecular equation that ended up being the whole thesis. For too long PhDs and Postdocs have been searching for answers. Here is a list of the most common questions for how to transition from academia to industry.

THE MOST IMPORTANT INDEPENDENT VARIABLES IN FERMENTATION. There are two key independent variables worth considering: (a) Sugar concentration. After crushing the grapes the next step in the making of wine is the fermentation of the grape juice and pulp with various yeasts and bacteria.

I have compiled a very solid list of the 12 most famous PhD theses (plural of thesis) in history. Do realize that this list includes ‘PhD Theses’ and not books/volumes (so Principia by Newton doesn’t count). Feedback and revision.

All along during the thesis preparation process, a student will receive feedback and should expect to do revisions. Revising a thesis based on feedback from the thesis supervisor, advisory committee and from the examiners is an important part of the thesis preparation process.
