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...

BACKGROUND Breast cancer is the most common malignant tumor in females worldwide. Many differences exist in clinico-pathological characteristics of breast cancer patients between China and Western countries. This study aimed to analyze clinico-pathological characteristics of breast cancer from central China. METHODS Clinico- pathological information on breast cancer from three hospitals in ce...

Vegetation is the most important component of terrestrial ecosystem. Scientific and quantitative analysis changes in vegetation quality great significance to realization ecosystem sustainability. Based on data remote sensing typical station monitoring, we examined dynamic NDVI (Normalized Difference Index) ecosystems from 1998 2020. We found that about 1/3 China’s regions had significantly impr...

The coordination and coupling of new urbanization the ecological environment is great significance for high-quality development Yellow River basin, China. In this paper, efficiency seven urban agglomerations in China, from 2006 to 2019 are calculated at city level. Spatial correlation analysis between carried out by applying spatial association model. Then, spatio-temporal relationship estimate...

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 ...
