A multimedia version of Piers-Harris Children's Self-Concept Scale 2 (Piers-Harris 2) was created with audio and cartoon animation to facilitate the measurement of self-concept among younger children. This study aimed to assess the psychometric qualities of the computer version of Piers-Harris 2 scores, examine its score equivalence with the paper-and-pencil version, and survey the respondent p...

introduction: bridges are certainly one of the most important structures but costly service elements in a transport system. the bridges are very required to access the damaged areas in emergency situations such as floods and earthquakes. scour around the foundations of bridge piers exposed to the flowing water than can destroy the bridge itself is a subject of major concern. flow pattern is kno...

Bridge piers which are constructed in the track of high water rivers cause some variations in the flow patterns. This variation mostly is a result of the changes in river sections. Decreasing the river section, bridge piers significantly impress the flow patterns. Once the flow approaches the piers, the stream lines change their order, causing the appearance of different flow patterns around th...

The relation between the happiness of 9–12 year old children and their temperament, popularity, and physical appearance was examined. Participants included 432 children and their parents and teachers. Happiness in children was assessed using a selfrating scale, parents’ ratings, teachers’ ratings, and the Happiness and Satisfaction Subscale of the Piers-Harris Children’s Self-Concept Scale 2 (P...

In existing European recommendations the drift capacity of unreinforced masonry (URM) piers is estimated as a function of the failure mode, aspect ratio and/or axial load ratio. The empirical relationships are based on a set of results from quasi-static cyclic tests on single URM piers, which were tested simulating either double-fixed or cantilever boundary conditions. In modern URM structures,...

Introduction... The construction or renovation of bridges may require placement of bridge piers in the channel or floodplain of natural waterways. These piers will obstruct the flow and cause an increase in water levels upstream of the bridge for subcritical flows. The increase in the water level is called the backwater. The amount of backwater caused by piers depends mainly on their geometric ...

scour around bridge piers is one of the most important fields of hydraulic research. local scour around bridge piers and abutment is one of the main reasons of bridge failures. in the field of scour at the bridges, researches are more focus on scour of piers in compare with abutment. while the available information on the bridge failures required cost, the major problems are related to abutment...

a large number of authors have studied to find out how to control scouring around a pier along direct stream. the objective of this research is then to study a scour pattern around such piers on curves rivers due to the fact that there may be a difference between a flow pattern on a direct line and the meander. thus, this study tries to check whether the use of cable and collar alone and in a c...

Functional life of any barrage project depends on functional stability of the concrete piers. The piers are constructed using concrete of different grades. Its durability is dependent on various factors viz. speed of running water, its aggressivity, temperatures fluctuations etc. The endurance capacity of these piers against these adverse conditions goes on reducing with passage of time. Gradua...
