This study presents the taxonomic description of two new sponge species that are intimately associated with the hyperarid mangrove ecosystem of Qatar. The study includes a preliminary evaluation of the sponges' potential ...
Effect of U-turns and heavy vehicles on the saturation flow rates of left-turn lanes at signalized intersections
(
MDPI
, 2020 , Article)
© 2020 by the authors. The Saturation Flow Rate (SFR) is a primary measure that can be used when estimating intersection capacity. Further, the efficiency of signal control parameters also depends on the accuracy of assumed ...
