Antioxidative activity and phenolic composition of pilotplant and commercial extracts of sage and rosemary
The direct toxicity of two essential oils,Majorana hortensis,Moench and Rosmarinus officinalis L.to adult females of the predacious mites,Amblyseius zaheri Yousef and El-Borolossy,Amblyseius barkeri (Hughes)and Typhlodromus athiasae Porath and Swirski were tested.Rosemary oil was the most toxic to fe- males of A.barkeri and the least to A.zaheri.In contrast,sweet marjoram oil was relatively toxic to T.athiasae and slightly toxic to A.barkeri.Both essential oils,decreased the food consumption rate at the concentration used for A.barkeri and A.zaheri.Females of A.barkeri and A.zaheri suffered a depression in reproduction when treated with 1% of rosemary oil.Both material used seems to be harmless to T.athiasae at 1%.

Lavender and rosemary are shrubs that have many medicinal uses. Like any other shrubs, they are susceptible to pest infection which needs pesticides treatment. Residues of pesticides in lavender and rosemary leaves may be hazardous to human health. The main objective of this study was to develop accurate and sensitive methods for the determination of residues of pesticides, namely, diazinon and chlorpyrifos, in lavender and rosemary leaves. Thin-layer chromatography (TLC) fractionation was applied to separate the desired pesticides to be analyzed and to determine the rate of the disappearance of these pesticides from lavender and rosemary leaves. Diazinon and chlorpyrifos were separated from extracts of leaves using silica gel 60 F254 plates. The mobile phase was formed of petroleum ether–ethanol–glacial acetic acid (9.5:0.5:0.1, v/v) and (9.0:1.0:0.1, v/v) as the developing systems for diazinon and chlorpyrifos, respectively, followed by densitometric measurement at 254 nm for both pesticides. The methods were validated over a range of 0.01–l.6 μg band−1 for diazinon and 0.04–2.0 μg band−1 for chlorpyrifos. The detection limits of diazinon and chlorpyrifos were 0.003 and 0.012 μg band−1, respectively. The safe harvest interval (pre-harvest interval; PHI), time in days between the last pesticide application to the crop and the time it can be safely harvested, was suggested to be 21 and 24 days for diazinon and chlorpyrifos, respectively. The developed TLC methods were used for sample cleanup and estimation of the studied pesticides residues in leaves extracts, in addition to the determination of the pre-harvest interval.
This paper suggests that the ultimate ‘otherness’ of children’s literature is not of ‘wildness’ in its many manifestations,
nor difference, nor ethnic heritage, nor even imaginative distinctiveness, although there exist telling examples of all of
these. Rather, it is the incipient otherness of non-being. Paradoxically, growth into beingness, into subjectivity and identity, is progressively and ever more insistently stalked by this otherness of non-being — of non-being
a child by growing up and out of ‘childhood’, of the potential nonbeingness of loved others, but most of all, and most deeply
and most profoundly, of knowledge of the inevitable non-being of self. That is, the ultimate other of children’s literature,
and indeed of life, is the otherness of death. This paper begins an exploration of these ideas by referring to three well-known
children’s plays, one that spans a century and has become a cultural icon and two that are the works of one of the best writers
of our day. The complex and sensual genre of plays for theatre — itself somewhat of an other in critical discussions of children’s
literature — offers a particularly acute focus for such a study: theatre involves writers and producers, actors and audiences,
in aesthetic and kinesthetic conventions that are at once corporate and intimate, physical and intellectual, visual and aural.
The plays for discussion are Peter Pan or The Boy Who Would Not Grow Up by J. M. Barrie, and Wild Girl, Wild Boy and Skellig, The Play both by David Almond.

The deterrent and toxic effect of two essential oils, Majorana hortensis. Moench and Rosma- rinus officinalis L. on the two tetranychid mites Tetranychus urticae Koch and Eutetranychus orientalis (Klein) were studied under laboratory conditions. Both materials used were more potent for E. orientalis than against T. urticae with a significant increase in repellency. Leaf discs treated with increasing concentrations of the two oils showed increased mortality of both spider mites and reduction in the total numbers of eggs laid. This result could be due to the oil of the higher oxygenated compounds content that was more effective in this respect.
