Genus Astroloba Uitewaal (Liliaceae)
… provide a much needed taxonomic revision of the genus Astroloba Uitew. Type material of all previously described species appears to be completely lacking. This revision was based almost entirely on living material collected by the author. Studies were made of morphological variation, geographical …

Studies on the genus streptococcus
… is 33-42% (Diebel and Seeley, 1974).</p> The genus Streptococcus includes a large number of saprophytic, pathogenic and non pathogenic species. Many of these bacteria are members of the normal body flora. However, man is very susceptible to the pathogenic members, and no organ in the body is …

Models of genus one curves
… we give insight into the minimisation problem of genus one curves defined by equations other than Weierstrass equations. We are interested in genus one curves given as double covers of P1, plane cubics, or complete intersections of two quadrics in P3. By minimising such a curve we mean making the …

Localization genus of classifying spaces
… K-theory filtered ring is an invariant of the genus. We apply this result in two ways. First, we use it to show that the powerseries ring on n indeterminates over the integers admits uncountably many mutually non-isomorphic [lambda]-ring structures. Second, we use it to study the genus of …

Point Counting On Genus 2 Curves
… a group, specially for hyperelliptic curves of genus 2. The best known algorithm for counting points on genus 2 curves over prime fields of large characteristic is a variant of Schoof’s genus 1 algorithm. Following a recent work of Gaudry and Schost, we show how to speed up the current state of …

Cytotoxic compounds from the genus Centaurea.
… of bioactivity of cytotoxic compounds from the genus Centaurea (Family: Asteraceae alto Compositae), a large genus of about 500 species. The first three chapters deal with an introduction of natural products and Centaurea species, followed by the isolation and characterisation of compounds from …

Otolith morphologies in the genus sinocyclocheilus
Sinocyclocheilus is a genus of Cyprinid fish found in southern China. This genus contains 68 species of which 40 species have adaptations for life in cave habitats. A common adaptation seen in fish that live in caves with no light is the loss of vision. Such cavefish must therefore rely on other …

Cytogenetic Studies in the Genus Cymbidium
<p>The orchids known today make up one of the largest Angiospermous families in the world. Recent estimates place the number of genera at about 450 which estimates between 10,000 and 15,000 species (some authorities go as high as 20,000). They are without doubt one of the most highly specialized …

Capitulation Discriminants of Genus One Curves
In this thesis we study genus one curves of degree n embedded in projective space P n−1 . We are speci cally interested in the curves de ned over Q that are counterexamples to the Hasse principle, that is the curves that have points everywhere locally but no Q-points. These curves correspond to …

Antigen analysis of the genus Candida
The purpose of the investigation was to apply the Ouchterlony Technique as a method of immunological assay of several species of Candida. The diffusion of antigen and antibody through the agar resulted in the formation of specific precipitates. The antisera were prepared by immunizing rabbits with …

Some studies on the genus Acaena
… taxonomy and synonymy of the two sections of the genus containing A.tenera and A.magellanica has resulted in the reduction to synonymy of many species, and a complete synonymyn for Sect. Acrobyssinoideae Bitt. and for A.magellanica (Lam.) Vahl (which comprises most of Sect. Ancistrum Bitt.) is …
