INTRODUCTION Dengue is a priority public health problem. During epidemics in Cuba and Haiti, ethnic African descendant population had lower risk of dengue, and the ethnic factor was proposed as a protective one. OBJECTIVE To determine the relation between the Dengue's cumulative incidence and the Afro-Colombian proportion in communities of Cali, during the epidemic of 2013. METHODS This stu...

In this paper we examine the effects of ethnicity on the gene flow between two groups living in Limón, Costa Rica. Our main interest is to determine if ethnicity has acted as a barrier to the exchange of genes, and if the groups have remained distinct genetically. We report the admixture estimates, F(st) values, and inbreeding coefficients of the two samples. The data consist of blood samples a...

According to the drive of planetary-scale upper magma fluid motions associated with core-magma angular momentum exchange in early Earth’s interior, this paper reviewed results continental drift studied over last three decades. The theoretical speculation is good fit traces geological events left on surface. A northeastward directionality Australian, African, and South American continents relati...

Spanish is characterized by number concord in determiner phrases (DPs) and predicate nominals; the plural marker /s/ is attached to all relevant elements in a plural DP. Exceptions to this rule usually involve phonetically motivated processes of /s/-weakening in coda position, and do not result in a functionally different system of plural marking. A distinct pattern is found in two isolated dia...

The most common hemoglobinopathies, viz, hemoglobins S and C, and α- and β-thalassemias, were investigated through the molecular screening of 116 subjects from the community of Saracura, comprising fugitive African slaves from farms of the municipality of Santarém, in the west of Pará State, Brazilian Amazon. The observed frequency of the HBB*S gene (0.9%) was significantly lower than that enco...

Discussions about the Adria microplate offer differing views depending on the timescale and data considered. Neotectonic studies using earthquake mechanisms and GPS site velocities find Adria moving northeastward away from Italy, and bounded by an extensional boundary in the Apennines and convergent boundaries in the Dinarides and Venetian Alps. However, geologic data show that Adria was subduc...

The Cananéia-Iguape lagoon-estuarine system, where the Ilha Comprida barrier (IC) is located, one of most dynamic coastal areas on southeastern Brazilian coast. IC island a 63 km-long and it limited by Icapara inlet to north, Cananéia south. This system has been affected intense changes in its morphology since opening Valo Grande artificial channel 1852 A.D., connecting nearby Ribeira de Iguape...

the zagros fold- thrust belt as a part of alpine- himalayan orogenic belt, is one of the most active continental collision zones on the earth, which extends from the tarus mountains in south eastern turkey to the minab fault in the east of the strait of hormoz in southern iran. structurally, its formation is related to the continuing convergent movement between the arabian plate to the southwes...
