Abstract As a contribution to the study of complex structures in native Amazonian languages, this article examines syntax additives and conjunctions language Gavião Rondônia. In particle k ĩ ´í ‘also, too, and’ is used form additive (‘also’) constructions with noun phrases verb phrases, without creating conjoined syntactic constituents. The same also constituents, which two or more are conjoine...

VIEWPOINT Conjoined twins are fused twins resulting from incomplete division of a single blastocyst, 13 to16 days post fertilization (1). Complete division of a human zygote within seven days of fertilization yields identical monozygotic twins (1). Fused body components, overlapping visceral components and impaired organogenesis characterize this anomaly (1–5). Classification of conjoined twins...

A conjoined twin is one of the rare congenital defects. Ischiopagus variety is even rarer. We present a case of ischiopagus-tripus conjoined twins. They were fused at the lower halves of the bodies. One of the twins was apparently normal looking, active and pink. The other twin was small, ill looking, sluggish and cyanosed. There were two well formed separate lower limbs on one side and a fused...

A case of vaginally delivered stillborn female thoracopagus conjoined twins is presented. Each twlin had a cleft lip and cleft palate. They shared a common pericardial sac and a common abdominal cavity. The liver was conjoined, and the small bowel was common to both twins. One twin was asplenic. Although the twins were monozygotic, their viscera were neither identical nor mirror-image to each o...

The occurrence of more than two ova from the same follicle (polyovular follicle) in humans has been observed. In this case report there was a high frequency of conjoined oocytes retrieved with individual zona pellucida (40% of oocytes retrieved, 4.3% of mature follicles) from women with polycystic ovary syndrome (PCOS). We may have to be more aware of the risk of multiple pregnancies in inferti...

The logic programming reenement calculus provides a method for transforming speciications to executable code, maintaining the correctness of the code with respect to its speciication. In this paper we show how types, and their generalisation, invariants, which allow conditions that relate several variables , can be handled in the logic programming reenement calculus. Types and invariants provid...
