EFFECT OF CELLULAR CONCRETE POWDER ON DURABILITY OF NORMAL STRENGTH CONCRETE

found in the literature that air-entraining agent highly increases frost resistance of concrete [2]. However, the price of air-entraining agent is high compared to the total price of concrete. 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

Unconfined compressive strength tests commonly used in the field of building materials enable the assessment of strength gain due to chemical reactions ongoing in the presence of binders. From geotechnical point of view this type of test does not reflect the real stress state

The prestressed case does not only decrease the deformability of a pipe on-load but it also protects metal from corrosion. The ability to withstand the arising stresses has been investigated for both strip fiberglass reinforcement and the whole construction. It has been shown that the deformability of fiberglass depends on the kind of binder. The maximum strength value has been

study highlights the need for clear, collaborative and ongoing communication between parents, teachers and EI staff in supporting autistic children during the transition to school. EI staff are recommended to provide support to families and receiving teachers, to develop knowledge and understanding of ASD. Using a strength based approach, harnessing a child’s skills and individualizing the transition process are essential for success.

DECOMPOSITION OF GENDER WAGE GAP IN POLAND USING COUNTERFACTUAL DISTRIBUTION WITH SAMPLE SELECTION

As the sample selection is a serious issue for the study, therefore our decomposition approach will be adjusted for sample selection problems. The results suggest not only differences in the income gap along the income distribution (in particular sticky floor and glass ceiling), but also differences in the

ESTIMATION OF SMALL AREA CHARACTERISTICS USING MULTIVARIATE RAO-YU MODEL

The growing demand for high-quality statistical data for small areas coming from both the public and private sector makes it necessary to develop appropriate estimation methods. The techniques based on small area models that combine time series and cross-sectional data allow for efficient "borrowing strength" from the entire population and they can also take into account changes over time. In this context, the EBLUP estimation based on multivariate Rao-Yu model, involving both

The role of DSCAM in the regulation of synaptic plasticity: possible involvement in neuropsychiatric disorders

Synaptic plasticity simply put, is the activity-dependent modification of the strength or efficacy of synaptic transmission in the network of synapses in the brain. The role of synaptic plasticity in disease is an active area of research. Changes in plasticity translate to the release of neurotransmitters at the synapse and subsequently, the way humans see the world. It is known that neuropsychiatric disorders such as depression, posttraumatic stress disorder (PTSD), and Alzheimer’s disease (AD

CRASH SAFETY OF A TYPICAL BAY TABLE IN A RAILWAY VEHICLE

addition, experimental dynamic (impact) tests are conducted using a pendulum representing a body block (mass). The results provide information about the possible loading of the table on the occupant in the event of a crash. Contact forces are compared with chest and abdominal injury tolerance thresholds to infer the collision injury potential. Recommendations are then made on design of bay tables to meet the “functional-strength-and-safety balance”.

A CASE STUDY ON PERCEPTIONS OF PUBLIC TRANSPORTATION IN THE EASTERN PROVINCE OF SAUDI ARABIA

The Eastern Province of the Kingdom of Saudi Arabia (KSA) is home to almost 5,000,000 people and is a major contributor to Saudi Arabia’s economic strength. The area has experienced population growth of about 3.5% per year and rapid urbanization over the past few decades. With this increase in population has come a significant escalation in automobile traffic, which, in turn, has contributed to poor air quality in the province. Two of the major cities in the area were listed on the World

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

A network approach to understanding obesogenic environments for children in Pennsylvania

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

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

Oppel-Kundt illusion balance

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

About 43% of the immobilized cadmium remained in roots after sequential extraction, and bioaccumulation factors in shoots had the same
