We examined young readers’ comprehension as a function of text genre (narrative, science), text cohesion (high, low), and readers’ abilities (reading decoding skills and world knowledge). The overarching purpose of this study was to contribute to our understanding of the fourth grade slump. Children in grade 4 read four texts, including one high and one low cohesion text from each genre. Compre...

The sensitivity of compressive strength of no-slump concrete to its ingredient materials and proportions, necessitate the use of robust models to guarantee both estimation and generalization features. It was known that the problem of compressive strength prediction owes high degree of complexity and uncertainty due to the variable nature of materials, workmanship quality, etc. Moreover, using t...

The production of tailor made high strength and high performance concrete are made by incorporating silica fume into the normal concrete and it is a routine one in the present days. The mix proportioning is intricate and the design parameters are increased due to the incorporation of silica fume in conventional concrete. The aim of this paper is to look into the different mechanical properties ...

The low back pain risks in a beef skinning operation at a high stand kill floor workstation was evaluated. The increases in compressive forces at lower back (L5/S1) between normal slump (back angle 25 degrees, measured in the sagittal plane) and severe (45 degrees ) and between normal slump and very severe (70 degrees ) bent back postures were 387 N or 28% and 616 N or 45%, respectively. The hi...

The main objective of this study is to evaluate the workability of fresh portland cement concrete while it is still in the mixing truck by determining fundamental rheological parameters (plastic viscosity and yield stress). Nine concrete mixtures with different values of yield stress and plastic viscosity were tested in a concrete truck. The measurements made with the truck were based on the ty...

Shrinkage can be critical factor for the design of structural members due to the length changes by the timedependent deformation. Given the high fluidity and different mixture proportions of SCC, the shrinkage of such concrete can differ from those of conventional concrete or HPC of normal consistency. Proper estimate of autogenous shrinkage of self-consolidating concrete (SCC) can provide engi...

In this paper, we view the Internet under a game-theoretic lens in an effort to explain and overcome the Internet’s innovation slump. Game Theory is used to model Internet environments as problems of technological competition toward the end of understanding their emergent phenomena and the evolutionary forces that shape them. However, our results extend beyond understanding the Internet archite...

 After a relatively widespread global slump, the outlook now varies greatly across world regions. Demand remains weak especially in those world regions where net savings are adjusting in such a way to rebalance external deficits. Against this background, the EU and the euro area itself cannot be considered as homogenous areas because some countries (“the center”) record external surpluses and ...
