AbstractWe are interested in finding solvability conditions for the Riemann boundary value problems for hyperanalytic functions in a simply connected bounded open subset of the complex plane whose boundary is merely required to be a d-summable closed curve.

a b s t r a c t Background: Many countries have introduced new vaccines and expanded their immunization programs to protect additional risk groups, thus raising the cost of routine immunization delivery. Honduras recently adopted two new vaccines, and the country contin...

9 pages, no figures.-- MSC2000 codes: 41A21, 65D15. MR#: MR1690593 (2000f:41020) Zbl#: Zbl 0943.41007 The block structure of the Padé table associated with a formal power series is well known. We study the analytic properties of the given power series in the case that a...

Rotavirus is the most common cause of acute gastroenteritis among infants and young children throughout the world, but rotavirus cases in developing countries account for nearly all of the approximately 600,000 annual deaths. We studied the epidemiology of rotavirus in ...

Chagas disease is the most important parasitic disease in Latin America. The causative agent, Trypanosoma cruzi, displays high genetic diversity and circulates in complex transmission cycles among domestic, peridomestic and sylvatic environments. In Ecuador, Rhodnius ec...

The immune response that develops in early childhood underlies the development of inflammatory diseases such as asthma and there are few data from tropical Latin America (LA). This study investigated the effects of age on the development of immunity during the first 5 y...

Abstract The main aim of this research is to create a model based on Artificial Neural Networks (ANN) that allows predicting the flow in Tomebamba river, at real time and in a specific day of a year. As inputs, this research is using information of rainfall and flow of ...

Abstract Based on a case study taken place in the jungle community of Santa Rita-Ecuador, we will refer on the negative and positive impacts of the technology transfer system, acknowledging the differences, seeing this as a product versus a process. The product approach...

Abstract Analysis of normal/pathological brain activity using neuroimaging methods is necessary to avoid operation risks, and the outcome serves as prior information for surgical neuronavigation. We present an fMRI/MEG/EEG-based methodology for tasks demanding mainly se...
