abstract in this study, fresh pistachio of 'ohadi' and 'akbari' cultivars expose to the uv-c radiation with a wavelength of 0, 3, 6 and 12 kj/m2, then located at temperature of 1 ± 3 degrees celsius for 45 days. properties or attributes, including weight loss, stiffness and sensory evaluation of fresh pistachio after 20 and 45 days storage were measured. results showed that pistachio nut weight...

The sustainability of the built environment is increasingly coming to the forefront of infrastructure design and maintenance decisions. To address this, development of a new class of more sustainable cement-based materials is needed. Fiber reinforced self-consolidating mortar (FRSCM) was developed by optimizing the micromechanical parameters, which control composite properties in the hardened s...

To provide data and methods for analyzing stem mechanics, we investigated bending, density and growth characteristics of 207 specimens of fresh wood from different heights and radial positions of the stem of one mature Norway spruce (Picea abies L. Karst.) tree. From the shape of each stress-strain curve, which was calculated from bending tests that accounted for shear deformation, we determine...

Bee pollen is becoming an important product thanks to its nutritional properties, including a high content of bioactive compounds such as essential amino acids, antioxidants, and vitamins. Fresh bee pollen has a high water content (15%-30% wt %), thus it is a good substrate for microorganisms. Traditional conservation methods include drying in a hot air chamber and/or freezing. These techniques...

ISSN 2277-5056 | © 2012 Bonfring Abstract--The workability of fresh concrete should be characterized by its rheological properties based on material science approach to overcome the inadequacies of traditional empirical tests like slump test. Generally the rheological properties of fresh concrete are described by Bingham parameters in terms of two physical quantities, namely yield stress and pl...

We introduce permissive nominal terms. Nominal terms extend first-order terms with binding. They lack properties of firstand higher-order terms: Terms must be reasoned on in a context of ‘freshness assumptions’; it is not always possible to ‘choose a fresh variable symbol’ for a nominal term; and it is not always possible to ‘alpha-convert a bound variable symbol’. Permissive nominal terms reco...

The influences of nano-ZrO2 (NZ), nano-TiO2 (NT), nano-Fe2O3 (NF) and nano-Al2O3 (NA) additions on properties of the fresh and hardened cement paste in comparison with the fine cement paste were experimentally studied. Mini slump and flow cone tests were conducted on fresh cement pastes. Moreover the compressive and tensile strength of hardened cement paste were measured. SEM micrographs and XR...

Optical properties of fresh and frozen tissues of rat heart, kidney, brain, liver, and muscle were measured in the 450- to 700-nm range. The total reflectance and transmittance were measured using a well-calibrated integral sphere set-up. Absorption coefficient μa and reduced scattering coefficient μ's were derived from the experimental measurements using the inverse adding doubling technique. ...
