Eosin Y has an extraordinary capacity to form complexes with metallic elements, that have applications in many different fields, from photovoltaics and photocatalysis historical artists’ pigments. To unravel the reactivity, it is essential a precise knowledge of their structure composition, as well how these can be affected by synthesis protocol, often underestimated factor. This manuscript pre...

This study investigated the alleviating effects of aromatherapy massage and acetaminophen on menstrual pain in Korean high school girls. Subjects were divided into two groups: the aromatherapy massage (treatment) group (n = 32) and the acetaminophen (control) group (n = 23). Aromatherapy massage was performed on subjects in the treatment group. The abdomen was massaged once using clary sage, ma...

Objective: Sweet potato whitefly, Bemisia tabaci Gen. (B. tabaci), is one of the most important pests of various greenhouse crops in Iran. Nowadays, chemical insecticides are broadly used for control of the pests that causes risk to consumer's health. For the first time, contact toxicity of Pelargonium roseum Andrews and Artemisia sieberi Besser essential oils on B. tabaci and its possible appl...

The filaree (Erodium cicutarium), a small, flowering plant related to geraniums, possesses a unique seed dispersal mechanism: the plant can fling its seeds up to half a meter away; and the seeds can bury themselves by drilling into the ground, twisting and untwisting in response to changes in humidity. These feats are accomplished using awns, helical bristles of dead but hygroscopically active ...

It can . . . come as a bit of a shock to meet your first non-obvious theorem, which will typically be Fermat’s Little Theorem. — Dominic Yeo [10] The non-obviousness of Fermat’s Little Theorem is the most interesting part of any introductory number theory course. We are therefore motivated to determine if Fermat’s Little Theorem can be extended to the Gaussian integers, as many other useful pro...

Essential oils from four plants, i.e. geranium, rosa, lemon and mint were tested for their activity in vitro and in vivo against Rhizoctonia solani and Fusarium oxysporum f. sp. phaseoli, the cause of root rot and wilt of beans. In vitro, they were found to have an inhibitory effect against the mycelial growth of R. solani and F. oxysporum f. sp. phaseoli. Complete inhibition in fungal growth w...
