The ideal relative permittivity of liquid mixtures is demonstrated to be a volume-fraction-weighted average of the pure-component relative permittivities. This generalised-thermodynamics result is used to define the molar electric dipole, permittivity, dielectric polarization and electric susceptibility of thermodynamically ideal liquid mixtures and the corresponding excess properties. A hyperb...

Pseudo-ensemble simulations and Gibbs–Duhem integrations are formulated within the framework of the expanded grand canonical ensemble. Pseudo-isobaric–isothermal simulations are proposed in which volume moves are replaced by fluctuations in the number of molecular segments. For large systems of dense athermal polymers, this pseudo-isobaric–isothermal method is shown to achieve mechanical equili...

We use micro particle image velocimetry (mPIV) and fluorescence microscopy techniques to characterize microscale segmented gas–liquid flow at low superficial velocities relevant for chemical reactions with residence times of up to several minutes. Different gas–liquid microfluidic channel networks of rectangular cross section are fabricated in poly(dimethylsiloxane) (PDMS) using soft lithograph...

Introduction: Interhemispheric transmission of signal is done by corpus callosum (CC) as the largest fiber tract in brain. CC comprised 5 segments of rostrum, genu, body, isthmus, and splenium. Contradictory reports exist about sexual dimorphism of CC. We designed this study to assess probable sexual differences of CC and its different parts in men and women. Methods: We analyzed magnetic reso...

This letter presents a novel reconfigurable microstrip patch antenna that is reconfigured using liquid metal. The proposed employs two approaches in unison to switch the direction of main beam. Specifically, uses parasitic steering approach together with switchable ground plane. operates at 5.9 GHz. It consists driven surrounded by four parasitics. All five elements are circular disk resonators...

Abstract Herein, we report a simple and versatile synthetic approach towards siloxane‐based poly(ionic liquid)s (PILs) with unusually low glass transition temperatures ( T g ) down to −73°C, thus “liquid‐like” behavior at room temperature. We designed polydimethylsiloxane‐derived copolymer carrying dialkylimidazolium moieties, by careful selection of the side‐chain length type anions were able ...

Transducin was [32P]ADP-ribosylated by cholera toxin in bovine retinal rod outer segments and then partially purified on omega-amino octyl agarose to remove other ADP-ribosylated proteins. Trypsin digestion of the ADP-ribosylated transducin and further purification using boronate-polyacrylamide beads and high performance liquid chromatography yielded a single radiolabeled tetrapeptide, Ser-Arg-...

During last decades, owing to the increase in a number of vehicles, the rate of accident occurrence grows significantly. Efforts must be made to provide efficient tools to prioritize segments requiring safety improvement and identify influential factors on accidents. This objective of the research was to determine the safety oriented threshold of International Roughness Index (IRI) to recognize...
