Predictions of how tropical forests will respond to future climate change are constrained by the paucity of data on the performance of tropical species under elevated growth temperatures. In particular, little is known about the potential of tropical species to acclimate physiologically to future increases in temperature. Seedlings of 10 neo-tropical tree species from different functional group...
Previous research has suggested that enhanced biological phosphorus removal (EBPR) from wastewater can be achieved under continuous aerobic conditions over the short term. However, little is known how environmental conditions might affect aerobic EBPR performance. Consequently we have investigated the impact of temperature, pH and dissolved oxygen (DO) concentrations on EBPR performance under s...
Modeling studies have predicted that coffee crop will be endangered by future global warming, but recent reports highlighted that high [CO2] can mitigate heat impacts on coffee. This work aimed at identifying heat protective mechanisms promoted by CO2 in Coffea arabica (cv. Icatu and IPR108) and Coffea canephora cv. Conilon CL153. Plants were grown at 25/20°C (day/night), under 380 or 700 μL CO...
Fertilized eggs of the American horseshoe crab, Limulus polyphemus, are buried in shallow nests above the high tide line, where they are exposed to variations in abiotic conditions during early development. Using a multiple-stressors approach, we examined whether the rate of embryonic development is affected by exposure to combinations of three factors: temperature (25, 30 and 35°C), salinity (...
The aim of this experiment was to determine the optimum feeding dose for juvenile common carp (Cyprinus carpio L.) with the average initial body weight of 0.88g (WB) and the total length of 37.9 mm (TL). The rearing was conducted for 10 days at the temperature of 27°C under controlled conditions. The fish were divided into 6 feeding groups (in triplicate), for which the doses of feed were estab...
let $g$ be a finite group and $pi_{e}(g)$ be the set of element orders of $g$. let $k in pi_{e}(g)$ and $m_{k}$ be the number of elements of order $k$ in $g$. set nse($g$):=${ m_{k} | k in pi_{e}(g)}$. in this paper, we prove that if $g$ is a group such that nse($g$)=nse($psl(2, 25)$), then $g cong psl(2, 25) $.

A field experiment was conducted in 2000 at the Agricultural Research Station, Isfahan University of Technology, to model the response of four safflower genotypes to day length and temperature changes under field conditions. Five planting dates (March 12, April 12, May 10, June 8, and July 12) and four safflower genotypes (Arak 2811, local variety Koseh, Nebraska 10 and Varamin 295) were evalua...
