An investigation into the chemical composition of alternative invertebrate prey.

Trophic niches, diversity and community composition of invertebrate top predators (Chilopoda) as affected by conversion of tropical lowland rainforest in Sumatra (Indonesia)

Conversion of tropical rainforests into plantations fundamentally alters ecological niches of animal species. Generalist predators such as centipedes (Chilopoda) may be able to persist in converted ecosystems due to their ability to adapt and switch to alternative prey populations. We investigated variations in community composition and trophic niches of soil and litter living centipedes in a r...

An Experimental Investigation of Reactive Absorption of Carbon Dioxide into an Aqueous NH3/H2O/NaOH Solution

In this research, the reactive absorption of carbon dioxide in an aqueous solution of NH3, H2O, and NaOH has experimentally been investigated. The experiments were carried out in an absorption pilot plant in different operational conditions. The composition and temperature of both gas and liquid phases were obtained during the column height. The concentration of molecular ...

Investigation of effect of Chemical composition of the preform on nano-layered Ti3SiC2 max phase synthesis using reactive melt infiltration process (RMI)

Ti3SiC2 bulks were synthesized using Si melt infiltration into porous preforms with different chemical compositions. The initial composition of the preforms was prepared on the basis of the TiC, 2TiC/Ti, 3TiC/0.3Si, 3Ti/2C (carbon active) and 3Ti/2C (graphite) formulations and was pressed into pellet using a cold press method. The Si ingots were weighed 3 times the stoichiometric value and in o...

Seasonal changes in icefish diel feeding patterns in Lake Chaohu, a large shallow eutrophic lake of China

Seasonal changes in the diel feeding patterns of the zooplanktivorous icefish (Neosalanx taihuensis), which is an endemic species of China, were studied in the large, shallow eutrophic Lake Chaohu of China during the autumn of 2002 and summer of 2003. The results of the diel feeding rhythm indicate that icefish is a visual particulate feeder. There were large differences in diet composition and...
