The Diacetyl concentration in beer depending on temperature and yeast strain

Imagine sitting down on a hot summer’s day with a glass of cold beer – and then discovering an aftertaste of butter! This is a real problem faced by the brewing industry. Because wort, which is used to brew beer along with yeast and a wide range of other ingredients, produces diacetyl during the fermentation process – and diacetyl tastes like butter. I became aware of this when carrying out a project for a Danish brewery with a grant from the Confederation of Danish Industries. So I decided to tackle the subject in my final-year biology dissertation. I carried out fermentation experiments using both baker’s yeast and brewer’s yeast to gain an insight into how temperature and yeast strain impact on the concentration of diacetyl in the beer. I have used this insight to come up with possible solutions for optimizing the removal of diacetyl from beer.

Creatine supplementation, nutritional supplement or doping?

Doping is an issue that attracts much media attention. It is illegal, it is cheating and it is not fair play. Athletes, who use shortcuts to enhance physical performance by drugging themselves with EPO, anabolic steroids and the like, run risks, however, of being found out by official doping tests. The doping list is an official catalogue of drugs known to improve physical performance. Many studies indicate that creatine also enhances some physical performances. This study is a survey of several of these former studies. On the basis of conclusions drawn from these studies and on personal tests, a sprint test and a vertical jump test, carried out by upper-secondary students, it is concluded that creatine supplementation does improve some sprint activities and that creatine should rightly be added to the doping list when a method – perhaps the one indicated in this study – of measuring unnaturally high levels of creatine has been found. Creatine is not only a nutritional supplement. It is doping.

Determining the speed of light from the movement of the Jupiter Moon Io

I have tried to determine the speed of light based on observations made by the famous Danish astronomer Ole Romer, who as the first scientist showed that light has a velocity, which he determined. The result was surprisingly close to today’s exact value, considering the methods and equipment he used. It is important to determine this value because of its usage in physics as well as in the everyday life. We have today more precise methods of doing so, but I think it is important to know of this alternative, yet original way.
