We present a multiple-scale approach for the analysis of tensile failure of concrete under impact loading. A phenomenological rate dependent constitutive model is applied at the macroscopic level. Viscosity terms are included to represent the strengthening effect associated with the microstructural moisture and inertial effects of micro-cracking. A partial length scale effect is extracted from ...

faba bean is one of the proper crops for cultivation in guilan climate conditions in rotation with rice. one of the limiting factors in development of cultivating this plant is late maturity and synchronizing of its ripening with rice transplanting. to investigate the effect of planting date, timing and consumption rate of paraquat herbicide on the ripening, grain yield and some of the agronomi...

The aim of this research was to analyze and compare 17 honey samples, 11 organic and six non-organic Apis mellifera honey. The samples were analyzed concerning moisture, hydroxymethylfurfural, diastase index, water activity, color, total sugar, reducing sugar, sucrose, ash, viscosity, electrical conductivity, pH, acidity, and formol index. With the exception of acidity, reducing sugar and diast...

Escape responses of fishes have long been studied as a model locomotor behavior in which hypothesized maximal or near-maximal muscle power output is used to generate rapid body bending. In this paper we present the results of experiments that challenged zebrafish (Danio rerio) to perform escape responses in water of altered viscosity, to better understand the effects that the fluid mechanical e...

In this work we assess the most recent estimates of glacial isostatic adjustment (GIA) for Antarctica, including those from both forward and inverse methods. The assessment is based on a comparison of the estimated uplift rates with a set of elastic-corrected GPS vertical velocities. These have been observed from an extensive GPS network and computed using data over the period 2009-2014. We fin...
