3.6.2 Riboflavin (vitamin B2)

Riboflavin or vitamin B2, which was originally known as vitamin G, is found in a wide variety of foods, including milk and dairy products. It is more stable to heat than some of the other B vitamins, but is destroyed by exposure to sunlight. Milk in a glass bottle exposed to sun, loses 10% of its riboflavin per hour. Riboflavin plays a crucial role in the metabolism of carbohydrates and proteins and is involved in many other metabolic reactions in the body.

Extending spatial DSS with spatial choice models of multipurpose shopping trip behaviour
Spatial choice or interaction models have been widely used in spatial DSS or customised GIS for analysing the impacts of retail location plans. The models typically used, however, do not account for spatial agglomeration effects on spatial choice behaviour. This study develops a model system for analysing the impacts of retail plans based on a choice model of multipurpose behaviour developed in earlier work. The model system is implemented in the spatial DSS called Location Planner. An empirical

Le secret des tortues vertes (video)

Est-ce le blanc immaculé des magnifiques plages de La Grande Glorieuse qui attire, tel un aimant, autant de tortues vertes, ou bien l'absolu isolement de cet archipel devenu, comme les autres îles éparses, une réserve naturelle ?
Le fait demeure, années après années, immuablement, ces reptiles marins, aujourd’hui protégés, reviennent en nombre se reproduire là.
Pour mieux comprendre ce phénomène de migration, le CNRS de Montpellier associé pour la circonstance

3.1 The helical structure of DNA

Having outlined the general principles of nucleic acid structures, we will now focus on how these principles influence the formation of specific structures found in DNA.

The helical structure of DNA arises because of the specific interactions between bases and the non-specific hydrophobic effects described earlier. Its structure is also determined through its active synthesis; that is, duplex DNA is synthesised by specialist polymerases upon a template strand. Within the helix, the two

Derivatives of Logarithmic Functions
This video demonstrates how the derivative of the natural logarithmic function (ln[x]) is simply 1 divided by x. It describes how this derivative can be found using both the definition of the derivative and a calculator. Derivatives of logarithmic functions are simpler than they would seem to be, even though the functions themselves come from an important limit in Calculus.  (5:13)
