Since the rose water is used in food, pharmaceutical, and cosmetic products, its microbiological control is necessary. Conventional pasteurization methods cause undesirable changes in taste, smell, medicinal properties and nutritional value with decreasing the amount of essential oil, because of high temperatures. In this study, the effects of the microwave power, temperature, ultrasound power,...

In this study, the effects of peppermint and rose extracts on delaying the aging of Alstroemeria spp. cut flowers were investigated. Peppermint and rose extracts were used in concentrations of 10, 20 and 30%. Quantitative and qualitative traits such as vase life, flower opening index, water uptake, fresh weight, dry weight, population of bacteria in vase solution and stem end, ion leakage, decr...

We assume without loss of generality that E{Xn} = 0. Let rs = i£{XnXn+s}. Then r8 = / I T edF(h), where F(X) is the spectral distribution function of the process. In §3 the spectral distribution function of any process of the form (2.2) is shown to be absolutely continuous. Finally it is shown in §4 that under some additional assumptions on the moment structure of the process the central limit ...

wind regime and sand grain size are two of the factors that determine the morphology and dynamics of sand dunes in desert areas. regarding the importance of wind effects on sand dunes especially in iran, in this study, khartooran erg was analyzed to determine wind direction and to detect sand source sites. khartooran erg is located on eastern north of iran and lies in khorasan razavi and semnan...

objective we have previously shown that rose bengal (rb) alone, not as a photosensitiser, could induce apoptotic- and non-apoptotic cell death in different melanoma cell lines. to clarify rb-induced toxicity mechanisms, role of caspases and reactive oxygen specious (ros) were studied in melanoma cells. material and methods human melanoma cell lines, me 4405 and sk-mel-28 were cultured in dmem m...

conclusions according to the present study, rose water noticeably reduces the anxiety of hemodialysis patients. therefore, inhalation of rose water can improve the patient’s emotional and spiritual condition during hemodialysis treatment. results mean scores of state and trait anxiety in the experimental group before intervention were 47/47 ± 7/6 and 49/56 ± 13/8, respectively; those after week...

This work uses the Weibull distribution for assessing wind potential in Senegal; a country located West Africa. In this study, data from ERA5 reanalysis and Ziguinchor station were used to characterize spatio-temporal variability of its available power density at 10 m 100 altitude. The results showed that was stronger on coast north-western part country. A case study carried out Basse Casamance...

abstract wind erosion of soils and suspended particles in iran is one of the serious environmental and agricultural problems which affect agricultural lands, water reservoirs, irrigation canals, drains and etc. therefore wind erosion control needs attention specially in arid and semi-arid regions. although in recent years, some polymeric materials have been used for improvement of structural st...
