the kashan erg is one of the most important sand dune complexes in iran. being affected by wind erosion, theerg's borderlands face numerous problems as a result of sand movement. to evaluate the risk of sands moving intoresidential areas near the kashan erg, anemometry data from synoptic stations located in kashan, ardestan, meimeh,naeen, and qom were collected and analyzed to calculate the san...

In the study, anaerobic digestion of residues from rose oil industry was investigated by using a laboratory scale completely mixed batch reactor in volume of 10 L and 4 small reactors in volume of 400 mL. Ten liters reactor isolated with a water jacket and 0.4 L reactors settled into a water bath were operated at 35 +/- 1 degrees C. The study supplies biochemical methane potential of hydrolyzed...

In vitro propagation of rose (Rosa indica) as well as rose breeding is a valuable economic enterprise and has received highest importance globally including Indian subcontinent. The development of new cultivars for commerce is faced with new challenges. In vitro micropropagation protocols of varieties of roses have been established but very few reports on the clonal propagation of local cultiva...

abstract background: pain is one of the common problems encountered by patients with burns, which increases after each dressing. this study aimed to investigate the effect of inhalation aromatherapy with damask rose essence on the pain of patients with burns that is caused after dressing. materials and methods: a randomized clinical trial was conducted on 50 patients with second‑ and third‑degr...

Whereaswater drops on both lotus leafs and rose petals have high contact angles, the drops can easily roll off lotus leafs but strongly adhere to rose petals. Here, we report a simple and cost-effective approach to fabricate highly stretchable large-area surfaces that give lotusleaf and rose-petal effects by harnessing origami patterns formed in graphene paper (GP) bonded on a pre-strained elas...

Rosa damascena petals were extracted by water, hexane and ethanol. The latter was further fractionated with chloroform, ethyl acetate and butanol. Rose oil and different petal extracts were evaluated against three fungi and eleven Gram-positive, Gram-negative and acid-fast bacteria. Rose oil and all extracts exerted broad spectrum antimicrobial activities against the tested organisms. The desce...
