Quaternion orders over quadratic integer rings from arithmetic fuchsian groups

In this paper we show that the quaternion orders OZ[ √ 2] ≃ ( √ 2, −1)Z[ √ 2] and OZ[ √ 3] ≃ (3 + 2√ 3, −1)Z[ √ 3], appearing in problems related to the coding theory [4], [3], are not maximal orders in the quaternion algebras AQ( √ 2) ≃ ( √ 2, −1)Q( √ 2) and AQ( √ 3) ≃ (3 + 2√ 3, −1)Q( √ 3), respectively. Furthermore, we identify the maximal orders containing these orders.

The exposure to Trichilia catigua (catuaba) crude extract impairs fertility of adult female rats but does not cause reproductive damage to male offspring

Ethnopharmacological relevance: Trichilia catigua is broadly used in folk medicine due to its mental and physical tonic activities and stimulant effects. In animal models, its antidepressant-like effects have been associated with the dopaminergic (DA) system modulation, which has an important role on maternal behavior and male offspring reproductive development.Aim of the study: Since little is known about the adverse effects of the exposure to T. catigua crude extract (CAT) in rats, specially regarding maternal homeostasis and offspring development, the aim of the present study was to evaluate whether CAT exposure may influence maternal toxicity parameters and behavior or disrupt male offspring physical and reproductive development.Material and methods: Dams were treated daily (by gavage) with 400 mg/kg of CAT or vehicle (control=CTR) throughout pregnancy and lactation. Fertility and maternal behavior tests were conducted in dams. Male offspring reproductive and behavioral parameters were analyzed.Results: Dams exposed to CAT showed increased pre- and post-implantation losses rates when compared to CTR group. No significant changes regarding maternal behavior or male offspring parameters were observed.Conclusion: In conclusion, maternal exposure to CAT interfered with implantation during the initial phases of pregnancy but did not induce changes on maternal behavior or male offspring reproductive and behavioral parameters.

Novos trilhos: a reinserção da área da estação ferroviária de Dracena no contexto urbano atual

Dracena, located in Presidente Prudente's region and founded in 1945, is a coffe and cotton's expansion and had your development by the advance of the Paulista Company of Railroads' tracks. For a long time the train was part of the city's and people's daily life. However, with the decline of rail trasport, the train station and a whole have become spaces without meaning and use. Thus, this final graduation work os Architecural and Urbanism course, aims to reintegrate in the urban área of Dracena Station and upgrade their space. To this end, based on the critical restoration theories and the projective references chosen were proposed the restoration of the railway station building and the creation of na annex for the Department of Culture. To enable the reintegration of the area into the urban fabric was proposed to create a linear park that provides a leisure space above the city and the lack of green areas. Preserving these spaces in a time when changes occur so quickly means keeping alive the memory and history of cities and allow new generations to take notice
