Study of parallel c...
In the middle of 1990, over 30 different mixes concretes with eight binders and water-binder ratios 0.3 to 0.75 were exposed a highway environment heavy de-icing salt spread for examination long-term performance, including chloride penetration, reinforcement corrosion frost attack. This paper presents results from this study regarding penetration corrosion. The show that in under road is much w...
This study, with the help of minimum temperature data, has addressed the prediction of frost during 21 years period by means of neural network in Kermanshah province. In order to forecast frost, data were converted to the values between 0 and 1 by means of a subjective and one to one (injective) function. We have used feed-forward neural network by one hidden interior layer with number of chang...
Despite extensive grouting efforts to prevent water from leaking into tunnels, seepages remain. When exposed freezing temperatures, ice formations occur. During the winter, Swedish Transport Administration's railway tunnels are affected by major problems caused ice, such as icicles roof and walls, loads on installations, ice-covered tracks roads, etc. To ensure safety traffic disruptions, many ...
This study was conducted to investigate the frost status in the 11 commercial cultivars, three newly introduced cultivars and two genotypes of olives. After the occurrence of frost at the Tarom region of Zanjan province in February 2019, three trees from each cultivar were selected. Frost symptoms were recorded based on observational indices. Gas exchange traits (stomatal conductance, transpira...
C. A. van den Berg, B. van den Bergen, H. Kroeze, L. W. Bartels, J. J. Lagendijk Dept. of Radiotherapy, University Medical Centre, Utrecht, Utrecht, Netherlands, Dept. of Radiology, University Medical Centre, Utrecht, Utrecht, Netherlands Introduction The application of MR imaging at high field (B0 ≥ 3 T, f ≥ 128 MHz) faces considerable challenges with respect to uniformity of the RF magnetic e...
Frost damage to the flowers and early developing fruits is one of the most limiting factors in almond cultivation regions of the world. This study was undertaken to understand almond response to frost damage concerning ion leakage in order to develop a criterion for the selection of frost-resistant cultivars in field experiments. In this work, 60 almond cultivars and genotypes on the basis fros...
