Besides that, air-entraining agents have negative effect on the compressive strength of concrete and usage is not allowed in case of some application area [3]. Another solution is the application of supplementary cementitious materials (SCMs, like metakaolin and silica-fume), which lowers the porosity of the

fixed-interval sweet reward provided a holistic ‘internal-external’ environmental strategic approach. One hypothesis was proposed; the intervention would be associated with a reduction in snack food consumption during the seven-day intervention period. Results indicated the number of snacks consumed was significantly reduced during the intervention. While methodological limitations precluded causal claims and strength and direction of relationships, evidence supported a behavioural

cement ratio was 0.23, the water (including 70% of the superplasticizer) to binder ratio 0.21. For mixtures with fibres the same straight fibre type was used with the length of 15 mm and diameter of 0.2 mm. The tensile strength of the fibres was higher than 2000 N/mm2. Size and shape of the specimens, production, storage, curing and testing of the specimens were according to ÖNORM EN 12390 [1] and ONR 23303 [2].

communities in Pennsylvania were used. Spearman correlation coefficients were used to describe the bivariate association between each pair of features. These correlations were used to create a network in which the nodes are community features and weighted edges are the strength of the correlations among those nodes. Modules of clustered features were identified using the walktrap method. This network was plotted, and then examined separately for communities stratified by quartiles of child obesity

concrete and the residual tensional strength after the first crack is due to the frictional stresses acting on the interface of the fibres and the concrete during the slipping of the fibres in the cracked zone.
In the new beam model according to Tóth, Pluzsik and Juhász [7] the fictive pull-out force was assumed to be constant. The aim of this work is to choose a more appropriate analytical model for the pull-out of synthetic fibres which can be built in the beam model to improve it and to gain a more

the original Oppel’s stimulus became a combination of two inducers, unequal in strength. During the length matching procedure, the expansion effect of the undivided inducer partly balanced that of the subdivided one. The author discerned the residue.
A complete theory on the neural mechanisms of the expansion effect has not yet been proposed (Wackerman, 2017). Originally, the illusion of interrupted extent was explained by the retina curvature (Hering, 1861; Kundt, 1863). Later studies invoked

Based on psychophysical experiments using Thurstone's Paired Comparison, VHI strength depends on the distance between two adjacent wires, and VHI caused by wide spacing of wires is considerably stronger than that caused by narrow spacing. In FEM analysis, a mesh model of fingertips is produced to mimic an actual finger to evaluate the strain energy density (SED) because one

bound with different strength in roots was significantly dependent on Cd concentration in the growth medium. When the plants were grown at 1 μg Cd ml–1, 9% of the immobilized cadmium was loosely bound to the root surface, 20% was exchangeable adsorbed, and 28% was bound by chelation; at 10 μg Cd ml–1, the respective values were 12%, 25%, and 20%. About 43% of the immobilized cadmium remained in roots after sequential extraction, and bioaccumulation factors in shoots had the same

The collected data were used for statistical analysis to determine the strength of the potential relationships. Results: In 146 out of 488 subjects perirenal fluid collections were found. In 1/3 of the patients more than one fluid collection was diagnosed. Over 40% of fluid collections were detected within 10 days from the date of the first scan and 24.11% were detected within 10–20 days from

On the basis of Region Zealand’s visitation history records, the cohort is expected to include approximately 100 to 120 children.The intervention groups participate in eight weekly group sessions that consist of separate parent and children’s groups. The control groups receive the standard treatment program as outlined by
