The impact of alien predators on native prey populations is often attributed to prey naiveté towards a novel threat. Yet evolutionary theory predicts that alien predators cannot remain eternally novel; prey species must either become extinct or learn and adapt to the new threat. As local enemies lose their naiveté and coexistence becomes possible, an introduced species must eventually become 'n...

This paper proposes a new idea for allocating handshake area of an automated container yard. A block yards (CY) consists two areas, which are the import (waterside) and export (landside) areas. The CY has major activities (loading unloading), where both served by Twin Automatic Stacking Cranes (Twin-ASCs). in middle serves as temporary slot ASCs. situation causes imbalance between ASCs when dem...

pistachio nut is one of the most important export crops in iran. for prevention of rancidity and to ensure good quality, pistachio must be harvested in a short time and be prepared for drying in 24h.the ohadi variety of iranian raw dry pistachio nuts was selected for the experiments. instrumental hardness and sensory characteristics of pistachio nuts such as: flavor , texture and total acceptan...

Sports ranking models were the main area of research for our REU project. We studied several different models and the theory behind them. Utilizing MATLAB as a programming language, we used these models to predict game outcomes and point spreads, and compare the relative value of statistics as indicators of team strength. Keener’s Direct Method (1993) ranking model was the starting point in our...

Urban forests are valuable spaces for species conservation, protection of local biodiversity and provision ecosystem services. However, they also vulnerable to the impact extreme climate events like hurricanes. Understanding how urban responding hurricane disturbances is crucial improve their design, management, resilience. Here we analyzed pre-and post-hurricane vegetation surveys in 52 reside...

The uranyl aryloxide, [UO2(OAr)2(THF)2], and uranyl chloride, [UO2Cl2(THF)3] or [UO2Cl2(THF)2]2 act as pre-catalysts for the ring opening polymerization of propylene oxide and cyclohexene oxide. Coordination of the monomers has been investigated using H EXSY spectroscopy and kinetic and thermodynamic parameters reported. NMR analyses of the polymers suggest a bimetallic mechanism for the polyme...

The 2,3,4-trideoxy-2,3,4-trifluoro hexose analogues of d-glucose and d-altrose were prepared and characterised and these novel sugar analogues were explored by 2D-(19)F-EXSY NMR for their potential to cross erythrocyte (red blood cell) membranes, by comparison with the well known capacity of erythrocytes to transport d-glucose.
