Physiographic characteristics of Atrak Watershed described by a number of parameters were used in regression models to estimate maximum daily discharges. These parameters were sub-watershed area, main waterway length, mean waterway slope, mean watershed elevation and mean watershed slope. Based on the results of correlation between the above parameters and their suitability for discharge estima...
Abstract The Blue Wave is a locking structure that allows simultaneous navigation in both directions of navigation, without stopping most cases, and at speed depending on the local topography. Its principle has been described an issue PIANC Bulletin, N°108, september 2001. It could be used, lieu set locks, Canal which presently being improved to CEMT Class Va, far upstream from Paris, Villiers ...
Automobile use has greatly increased during the last few decades. The number of passenger kilometers by private car per capita increased by 90 percent in Western Europe and 13 percent in the US between 1970 and 1990. In 1990, the average number of passenger kilometers travelled by private car in the US (18,650 km) was more than double the Western European figure (8710 km; OECD, 1996). The numbe...
As the advancement of technology, online shopping channel develops rapidly in recent years. According to the report of Taiwan Network Information Center, there are almost eighty percents of internet population shopping in online channel. Synthesizing insights from the previous research, this study develops the conceptual model to integrate Theory of Perceived Risk (TPR) and Technology Acceptanc...
Background: Post-stroke recovery benefits from structured, intense, challenging, and repetitive therapy. Exergames have emerged as promising to achieve sustained therapy practice and patient motivation. This study assessed the usability and effects of exergames on balance and gait. Subjects and Methods: Sixteen elderly participants were provided with the study intervention based on five newly d...
distribution patterns of ectothermic marine organisms (Fields et al., 1993; Barry et al., 1995; Hughes, 2000). Wholeorganism thermal tolerance limits closely reflect differences in habitat temperature that result from different latitudinal and vertical distribution patterns (Vernberg and Tashian, 1959; Edney, 1961; Stillman and Somero, 1996; Stillman and Somero, 2000; Tomanek and Somero, 2000)....
Natural parameters are one of the main determinants of the physical development of cities and settlements. In a mountainous area, the effects of these factors have become a barrier to development and can have natural hazards. In this research, it is tried to identify the optimal directions of physical development of the city of Nurabad as a relatively high region by identifying its effective fa...
IntroductIon Rapid changes in the field of knowledge management (KM) have to a great extent resulted from the dramatic progress we have witnessed in the field of information and communication technology. ICT allows the movement of information at increasing speeds and efficiencies, and thus facilitates sharing as well as accelerated growth of knowledge. For example, computers capture data from m...
The purpose of this research was to identify the structural adaptations in three populations of Convolvulus persicus L. on coastal areas in Mazandaran Province, whose populations of which are severely reducing due to the intense environmental stresses of the coastal zone. In general, annular collenchyma, isobilateral mesophyll, amphiphloic siphonostele, abundant presence of laticiferous tubes, ...
