This study, a partnership between <Organization 1> and 2>, investigated whether attending full-time kindergarten (FTK) was associated with better educational outcomes for Metis students in Manitoba, who may face unique barriers to academic success. We utilized linked administrative data from the Manitoba Population Research Data Repository. For each measured education outcome, there we...
When performing a regional-scale geomorphometric analysis, one might face a decision on whether to derive morphometric data from a low-resolution DEM or to calculate basic derivatives from a higher resolution dataset and average these data afterwards. This paper investigates differences between morphometric parameters (slope and aspect) derived from a resampled DEM and resampled morphometric da...
To explore the water flow characteristics under action of floating rigid vegetation groups, several laboratory tests are conducted in a flume North Minzu University, which is replaced by glass rods. In tests, two groups placed at different positions and length into changed. Experimental results show that both upstream level group surface slope along way grow with increasement root. When root be...
Water control technology aims to provide a sufficient water supply avoid overflow. An automatic valve sluice gate made from fiberglass is preferred for in tidal agriculture. The mechanical model can automatically release and close discharge at precise angle optimize advantage of this design its utilization the difference between upstream downstream levels on gate. A with slope 15° recommended l...
Advances in genomics research have called forth new strategies for patenting DNA sequences. Gene patenting, which began inconspicuously in the early days of the biotechnology industry in the 1970s and 1980s, did not generate significant public controversy until the advent of high-throughput DNA sequencing in the 1990s. By this point, it was such a well-established practice that categorical chal...
Abstract The most important design index of water intakes is critical submergence depth the intake. at which air core formed by vortex about to enter emergence a and entry into intake increase head loss decrease discharge coefficient. reservoir geometric asymmetry, presence unevenness in bottom angle approach flow are among factors that influence formation depth. In this research, physical mode...
Iranians have a very long history of water harvesting to address water scarcity and the consequences of frequent droughts. Among these strategies, Bandsar is a wide spread indigenous practice, which has been utilized in the central and the southern part of Khorasan province (the northeast Iran). Bandsar in Persian means a series of consecutive bands, berms, levees, or dikes. A Bandsar consists ...
