lath June 1890. Disease.?Vaginal atresia (Imperforatehymen hypertrophied). A girl named Gadi, ait. 15 years, a dhobi by caste, residing in Muthanapallij was admitted into the Municipal Hospital, Guntur, 011 the 5th June 1890, stating that she never menstruated up to date, and that about five days ago she felt bearing-down pains in the loins and lower abdomen, which drew her attention to a tense...

Crawling using muscular waves is observed in many species, including planaria, leeches, nemertea, aplysia, snails, chitons, earthworms and maggots. Contraction or extension waves propagate along the antero-posterior axis of the body as the crawler pushes the ground substratum backward. However, the observation that locomotory waves can be directed forward or backward has attracted much attentio...

Partial 18S rRNA sequence of the nemertine Cerebratulus lacteus was obtained and compared with those of coelomate metazoans and acoelomate platyhelminths to test whether nemertines share a most recent common ancestor with the platyhelminths, as traditionally has been implied, or whether nemertines lie within a protostome coelomate clade, as suggested by more recent morphological analyses. Maxim...

The San Marcos River in Central Texas has been well studied and has been demonstrated to be remarkably specious. Prior to the present study, research on free-living invertebrates in the San Marcos River only dealt with hard bodied taxa with the exception of the report of one gastrotrich, and one subterranean platyhelminth that only incidentally occurs in the head spring outflows. The remainder ...

We propose a model that generates an economic expansion following good news about future total factor productivity (TFP) or investmentspecific technical change. The model has three key elements: variable capital utilization, adjustment costs to investment, and preferences that exhibit a weak short-run wealth effect on the labor supply. These preferences nest, as special cases, the two classes o...

This paper presents the implementation of ARQ-PROP II, a limited-depth propositional reasoner, via the compilation of its specification into an exact formulation using the satyrus platform. satyrus’ compiler takes as input the definition of a problem as a set of pseudoBoolean constraints and produces, as output, the Energy function of a higher-order artificial neural network. This way, satisfia...

One of the most remarkable larval types among spiralians, and invertebrates in general, is the planktotrophic pilidium. The pilidium is found in a single clade of nemerteans, called the Pilidiophora, and appears to be an innovation of this group. All other nemerteans have either planktotrophic or lecithotrophic juvenile-like planuliform larvae or have direct development. The invention of the pi...

Accumulating evidence shows that increased biodiversity has a positive effect on ecosystem functioning, but the mechanisms that underpin this positive relationship are contentious. Complete extinctions of regional species pools are comparatively rare whereas compositional changes and reductions in abundance and biomass are common, although seldom the focus of biodiversity-ecosystem functioning ...
