P, Vm, 7" data were established for 4'-n-hexyl-biphenyl-4-carbonitrile (6CB) and 4'-n-heptyl-biphenyl-4-carbonitrile (7CB) between 300 and 370 K up to 300 MPa, and specific volumes were determined for the liquid crystalline, isotropic, and also partly for the crystal phases. Volume and enthalpy changes at the phase transitions are also presented. In the case of 6CB, a new crystal phase has been...

The article examines the effect of thermal insulation from autoclaved aerated concrete on energy characteristics a single-family house. Analysis mathematical models external enclosing structures buildings depending thickness AEROC products according to criteria heat loss shows that resistance value 7.11 m2K/W and transfer coefficient 0.141 W/(m2K) are achieved using wall block D 300 Energy pane...

OBJECTIVE The aim of this study was to evaluate the microhardness of radicular dentin after treatment with 980-nm diode laser and different irrigant solutions. BACKGROUND DATA There are few reports of the consequences of diode laser irradiation emitted at 980 nm on the mechanical properties of dentin. METHODS Seventy-two single canal, human canines with complete root formation were randomly...

Nitrifying bacteria (NH4+ and NO2oxidizers) are capable of recovery from photoinhibitlon in the dark. After short-term (2 to 4 h) irradiations, significant differences were found between the 2 groups. NH,' oxidizers subjected to longer wavelengths (>400 nm; 25 W m-2) or polychromatic light (15 W m-2) regained activity faster (0.5 to 1 h) than if exposed to shorter wavelengths (<400 nm; 25 W m-'...

La Biblioteca Digital de la Universidad de Castilla-La Mancha pretende ser ofrecer todas las posibilidades de una biblioteca tradicional, tanto en cuanto a recursos como a servicios, y no quedarse en una mera colección de textos accesibles pero desorganizados. Se presenta esta biblioteca desde su gestación hasta el momento actual mostrando las posibilidades que ofrece y la experiencia de su pue...

Methanolic and aqueous extracts of Dendrophthoe falcata Linn. leaves which belongs to the Loranthaceae family, were evaluated through DPPH (1, 1-diphenyl -2-picryl-hydrazyl), antilipid peroxidation and nitric oxide scavenging methods to assess the antioxidant activity. Methanolic and aqueous extracts of Dendrophthoe falcata leaves were also evaluated for their anti-inflammatory activity by carr...
