mathematical techniques. When the "objects" considered have specific properties, it is possible to envisage (and even to recommend) how to exploit these properties for performing dimensionality reduction. One example of this approach consists in replacing images of centro-symmetric particles by their rotational power spectrum (Crowther and Amos, 1971): the image is split into angular sectors, t...

Recommendations for the management of tyrosinaemia type 1 Corinne

The management of tyrosinaemia type 1 (HT1, fumarylacetoacetase deficiency) has been revolutionised by the introduction of nitisinone but dietary treatment remains essential and the management is not easy. In this review detailed recommendations for the management are made based on expert opinion, published case reports and investigational studies as the evidence base is limited and there are n...

The Gauss-bonnet Theorem

The Gauss Bonnet theorem links differential geometry with topology. The following expository piece presents a proof of this theorem, building up all of the necessary topological tools. Important applications of this theorem are discussed.

The Gauss-Bonnet Theorem

Teenagers ́ unintended pregnancies and contraception by Gabriella Falk

Teenage pregnancies are often not intended, and there is a high risk that unintended pregnancies will lead to abortion. The wide-spread availability of Youth Clinics, the subsidizing of contraceptives and the introduction of new and effective contraceptives have failed to lower the abortion rates. The aim of this thesis was to study possible risk groups and to highlight underlying reasons for c...
