Infective Causes of Stroke in Tropical Regions

Vascular diseases of the brain are the second reason of the death and the first cause of morbidity and disability worldwide. In tropical areas stroke has some particular features related to the nature of torrid zones. There are some special causes of the stroke, mainly infectious, although some of them are non-infectious. The most important etiologies are malaria, tuberculosis, cysticercosis, s...

of Tropical Diseases Tropical Sprue

One of the more mysterious and still rather poorly understood diseases seen in the tropical regions of the world is Tropical Sprue (TS). TS is a clinical syndrome with an unknown etiology typically characterized by an acquired chronic diarrheal illness, small bowel mucosal abnormalities and malabsorption resulting in nutritional deficiencies and weight loss [1]. These are vague symptoms which c...

Tropical cyclogenesis in tropical waves

The development of tropical depressions within tropical waves over the Atlantic and eastern Pacific is usually preceded by a " surface low along the wave " as if to suggest a hybrid wave-vortex structure in which flow streamlines not only undulate with the waves, but form a closed circulation in the lower troposphere surrounding the low. This 5 structure, equatorward of the easterly jet axis, r...

Tropical Arithmetic & Algebra of Tropical Matrices

The purpose of this paper is to study the tropical algebra – the algebra over the tropical semi-ring. We start by introducing a third approach to arithmetic over the max-plus semi-ring which generalizes the two other concepts in use. Regarding this new arithmetic, matters of tropical matrices are discussed and the properties of these matrices are studied. These are the preceding phases toward t...

Tropical lines on smooth tropical surfaces

Given a tropical line L on a tropical surface X, we define its combinatorial position on X to be a certain decorated graph, showing the relative positions of vertices of X on L, and how the vertices of L are positioned on X. We classify all possible combinatorial positions of a tropical line on general smooth tropical surfaces of any degree. This classification allows one to give an upper bound...
