ziziphus spina-christi are distributed in arid and semi-arid regions of world. most of these areas are subjected to soil salinity. so, the aim of this study was to find out the effects of different nacl concentrations on z. spina-christi seedlings growth, in the presence of a number of single and dual amf inoculums, to provide some information about possible effects of amf under salinity condit...

The title compound, C(22)H(28)O, was isolated from the aerial part of Inula viscosa- (L) Aiton [or Dittrichia viscosa- (L) Greuter]. The cyclo-hexene ring has a half-chair conformation, whereas the cyclo-hexane ring displays a chair conformation being substituted at position 2 by a 3-(4-methyl-phen-yl)prop-2-enoyl group. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules ...

The title compound, C(16)H(24)O(3), was isolated from the aerial part of Inula Viscosa- (L) Aiton [or Dittrichia Viscosa- (L) Greuter]. The mol-ecule contains two fused (trans) six-membered rings which both exibit a chair conformation. In the crystal, mol-ecules are linked into chains along [100] by weak C-H⋯O hydrogen bonds involving the methyl and carbonyl groups.

Virtual reality is a new technology used in the treatment of nicotine addiction that involves immersing smokers in environments with specific stimuli in order to reduce the level of craving. The present study aims to present a new virtual reality technology (in this case, Oculus Rift) used to assess craving of Romanian smokers. Results showed that smokers feel a higher craving after the exposur...

the antioxidant activities of methanol (me), ethanol (ee), water (we) and ethyl acetate (eae) extracts of four inula helenium l. taxa (i. helenium ssp. orygalis (boiss.) grierson, i. helenium ssp. pseudohelenium grierson, i. helenium ssp. turcarasemosa grierson and i. helenium ssp. vanensis grierson) were investigated. the phosphomolybdenum assay, β-carotene–linoleate bleaching and dpph radical...

High elevation montane areas are called "sky islands" when they occur as a series of high mountains separated by lowland valleys. Different climatic conditions at high elevations makes sky islands a specialized type of habitat, rendering them naturally fragmented compared to more continuous habitat at lower elevations. Species in sky islands face unsuitable climate in the intervening valleys wh...

Ziziphus Spina-Christi bark and other natural debris may be found in abundance the nearby area. The mechanical qualities of all these waste resources are outstanding, they utilized more professionally to create composite materials for a variety applications. Epoxy resin modified with organic particles such as powder has been used reinforcements polymer matrixes instead non-degradable synthetic ...
