Claude Monet: A Collection of 1540 Paintings (HD)
This may be good for students in a study hall or entering an art classroom. Claude Oscar Monet was born in Paris on November 14, 1840. Soon after, his family moved to Le Havre, where he spent his youth. His acquaintance with Eugène Boudin lead to Monet seriously pursueing his education as a painter in 1858. Boudin and Jongkind taught Monet to always work in the field in front of his motif. The following year Monet went to Paris anyway to begin academic training. (02:08:21)

2.4.3 Sulfur (S)

Most proteins contain about 1% sulfur, which occurs in the side-chains (R groups) of two of the protein-forming amino acids, methionine and cysteine.

Cysteine is particularly important in proteins such as collagen (found in bone, tendons, cartilage and skin) and keratin (found in hair and nails, as well as skin).

2.7.5 Email providers

These are sites which provide free email facilities; often they provide other facilities such as sending anonymous mail and constructing mailing lists. Such sites are valuable to users who are too impecunious to be able to afford conventional mailing software and to frequent travellers who can access such sites anywhere in the world. Their main disadvantage is that they tend to be slow compared with conventional mailing utilities such as Microsoft Outlook and Eudora.

Introduction

This is the fifth and final unit in the MSXR209 series on mathematical modelling. In this unit we revisit the model developed in the first unit of this series on pollution in the Great Lakes of North America. Here we evaluate and revise the original model by comparing its predictions against data from the lakes before finally reflecting on the techniques used.

This unit, the fifth in a series of five, builds on ideas developed and introduced in Modelling pollution in the Great Lakes

1.6 Vitamin B

Vitamin B, often called the vitamin B complex, consists of a whole range of different compounds, some of which have similar functions and work together. However, unlike the families of compounds forming vitamins E and K, the B vitamins are sufficiently different from one another to be given individual names or numbers, and to be listed separately on many food labels. Except for vitamin B12, the body can only store limited amounts of B vitamins and because they are all water-soluble
