elevated tanks are important structures in storing vital products, such as petroleum products for cities and industrial facilities, as well as water storage. these structures have various types and are constructed in a way that a greater portion of their weight is concentrated at an elevation much about the base. damage to these structures during strong ground motions may lead to fire or other ...

Functionalization of [60]fullerene with liquid-crystalline dendrimers and a dibutylaniline-based phenylenevinylene moiety leads to supramolecular materials, the fluorescence of which responds to acid-base stimuli.

A nanofluid is a dilute liquid suspension of particles with at least one critical dimension smaller than ~100 nm. Research works so far suggest that nanofluids offer excellent heat transfer enhancement over conventional base fluids. The enhancement depends on several factors such as particle shape, particle size distribution, volume fraction of nanoparticles, temperature, pH, and thermal conduc...

background: biloma is a rare abnormal localized accumulation of bile out of biliary tree due to an injury. it has different non-specific clinical features and its diagnosis is based on clinical signs, radiologic findings and chemical analysis of aspirated liquid. considering the non-specific clinical features, early diagnosis and treatment can have an effective role in the decrease of complicat...

A three-dimensional computational fluid dynamics model of a proton exchange membrane fuel cell (PEMFC) with both gas distribution flow channels and Membrane Electrode Assembly (MEA) is developed. A set of conservation equation is numerically solved by developing a CFD code based on the finite volume technique and SIMPLE algorithm. In this research, some parameters like oxygen consumption, water...

The liquid crystal (LC) compound with the central linkage group Schiff-base was studied. molecular structure characterized FTIR. Mesomorphic properties were using differential scanning calamity (DSC) and polarizing optical microscopy (POM). dielectric constant (ε) conductivity (σ) anisotropy (Δε) have been measured in frequency range of 100 Hz to MHz from room temperature l00 °C. Dielectric con...
