this experiment was designed to characterize the effects of size and concentration of an iranian clinoptilolite zeolite on the growth officus benjamina (starlight) in peat base media. ficus benjamina was stock rooted and grown in a peat consisting perlite (2: 1 v/v) (p: pe), zeolite (10, 20, 30 and 40 v/v %, two sizes 0.5-3 mm and 3-8 mm) instead of peat in p: pe (2: 1 v/v) media. ficus benjami...

In her article "McCarthy's The Road and Ethical Choice in a Post-Apocalyptic World" Jingjing Guo analyses ethical choice and its implications in McCarthy's The Road. After examining the deterioration of the ethical context and the prevalence of evil reflected in cannibalism, Guo highlights the father's ethical choice and dilemma. Different from most others, the father chooses to keep alive to p...

Metal coordination chemistry is common in biology, with many proteins containing metal ion-based structural motifs or catalytic centers. An interesting example of nature’s use coordinate bonding to create a proteinaceous material found the Alitta virens marine worm jaw. Inspired by Zn+2 cross-linked polymers A. virens, we have extended cross-linking preceramic polymers. Commercially available S...

BACKGROUND In continuation of our previously interest in the saccharification of agriculture wastes by Bacillus megatherium in solid state fermentation (SSF), we wish to report an investigation and comparative evaluation among Trichoderma sp. for the saccharification of four alkali-pretreated agricultural residues and production of hydrolytic enzymes, carboxymethyl cellulase (CMCase), filter pa...

Figs are the inflorescences of fig trees (Ficus spp., Moraceae). They are shaped like a hollow ball, lined on their inner surface by numerous tiny female flowers. Pollination is carried out by host-specific fig wasps (Agaonidae). Female pollinators enter the figs through a narrow entrance gate and once inside can walk around on a platform generated by the stigmas of the flowers. They lay their ...

Studies have only recently begun to underline the importance of including data on the physiological flexibility of a species when modelling its vulnerability to extinction from climate change. We investigated the effects of a 4°C increase in ambient temperature (Ta), similar to that predicted for southern Africa by the year 2080, on certain physiological variables of a 10-12 g passerine bird en...
