OBJECTIVE Handling of endodontic sealers is greatly dependent on their elasticity and flow ability. We compared the viscoelastic properties of three root canal sealers. MATERIALS AND METHODS AH Plus (Dentsply, De Trey, Konstanz, Germany), Endofill (Dentsply Hero, Petrópolis, Rio de Janeiro, Brazil) and AH26 (Dentsply, De Trey, Konstanz, Germany) were mixed according to the manufacturers' inst...

Various proteins and peptides are able to self assemble into amyloid fibrils that are associated with disease. Structural characterisation of these fibres is limited by their insoluble and heterogeneous nature. However, advances in various techniques including X-ray diffraction, cryo-electron microscopy and solid state NMR have provided detailed information on various amyloid fibrils, from the ...

Response surface methodology was used for quantitative investigation of water and solids transfer during osmotic dehydration of beetroot in aqueous solution of salt. Effects of temperature (25 – 45C), processing time (30–150 min), salt concentration (5–25%, w/w) and solution to sample ratio (5:1 – 25:1) on osmotic dehydration of beetroot were estimated. Quadratic regression equations describing...

Solid waste management in steel industry is broadly classified in “4 Rs” i.e. reduce, reuse, recycle and restore the materials. Reuse and recycling the entire solid waste generated in the process of steel making is a viable solution in targeting a clean, green and zero waste technology leading to sustainable development of the steel industry. Solid waste management has gained importance in stee...

Despite recent increases in recycling, composting, and incineration, the sanitary landfill remains the predominant and most economical municipal solid waste (MSW) management alternative. Modern MSW landfills strive to optimize the design, construction, and operation processes in order to mitigate many of the potentially negative impacts, and improve the profitability. The bioreactor landfill (B...

Accurate mechanical property data obtained at large shear deformations and high frequencies are a fundamental component of realistic numerical simulations of soft tissue injury. Although many commercial systems exist for testing shear properties of viscoelastic materials with properties similar to soft biological tissue, none are capable of determining properties at high loading rates necessary...

Long-term spatial and temporal variations in temperatures have been investigated in covers, wastes, and liners at four municipal solid waste landfills located in different climatic regions: Alaska, British Columbia, Michigan, and New Mexico. Temperatures were measured in wastes with a broad range of ages from newly placed to old �up to 40 years�. The characteristic shape of waste temperature ve...

Plutonium-contaminated solid wastes including combustible, incombustible and chlorine contained waste have been generated during Mixed Oxide,(MOX) fuel fabrication by Japan Atomic Energy Agency (JAEA). Incinerations of chlorinated wastes cause the problems related to corrosion of the equipments and dust loading in the vent exhaust system. The JAEA has designed and manufactured a new type incine...

The past ten years have seen the advent of silicon-based precise timing detectors for charged particle tracking. underlying reason this evolution is a design innovation: Low-Gain Avalanche Diode (LGAD). In its simplicity, LGAD an obvious step with momentous consequences: low gain leads to large signals maintaining sensors stability and noise, allowing sensor segmentation. Albeit introduced diff...
