we show that the category of convergence approach spaces is a simultaneously reective and coreective subcategory of the category of latticevalued limit spaces. further we study the preservation of diagonal conditions, which characterize approach spaces. it is shown that the category of preapproach spaces is a simultaneously reective and coreective subcategory of the category of lattice-valued p...

transient hypogammaglobulinemia (thi) of infancy is a common primary immunodeficiency usually resolves by 3 years of age. in this study, clinical, immunological data and outcome of 101 retrospectively diagnosed thi patients were evaluated. majority of them suffered from recurrent respiratory infections (70.3%). initial igg, igm and iga levels were 446.7±121.5, 67.5±32.8, and 25.6±16.8 mg/dl, re...

the prevalence of physical violence during pregnancy varies widely in different societies. to assess the incidence of self-reported physical, emotional and sexual violence in pregnancy and describe the association with maternal complication and birth outcomes, 3275 women who gave birth to live-born infants from october 2002 to november 2003 were assessed for self-reported violence in postpartum...

urbanisation is still one of the social themes in developing countries. in china, the rapid process of urbanisation and economic growth bring to people not only more opportunities for creating new life and pursuing happiness, but also the challenge to face various and complex social, economical and environmental problems. among them some are outstanding, like the shrinking plowland devoured by ...

In the present paper, we discuss singular minimal surfaces in Euclidean $3-$space $\mathbb{R}^{3}$ which are minimal. Such a surface is nothing but plane, trivial outcome. However, non-trivial outcome obtained when modify usual condition of minimality by using special semi-symmetric metric connection instead Levi-Civita on $\mathbb{R}^{3}$. With this new connection, prove that, besides planes, ...
