in order to examine the effects of essential oils and silver nanoparticles as anantimicrobial preservative in the solutions of alstroemeri cv. sukari cut flowers, anexperiment was conducted with 11 treatments and 3 replications in a completelyrandomized design. in this study, we used essences of carvacrol, thymol and zataria oilwithconcentrations of 50 and 100 mg l-1 and silver nanoparticles wi...

lisianthus (eustoma grandiflorum cv. ‘mriachii blue’) is one of the most important and marketable cut flowers in the world. however, a relatively limited vase life reduces its marketability. the aim of the present study was to evaluate the effects of essential oils in extending vase life of cut flowers of lisianthus. for this purpose a factorial experiment based on a completely randomized desig...

Original scientific paper To enhance underground mining safety, researchers developed high-water and fast-setting cement (HWFSC). HWFSC essentially consists of two components and can be mixed with large quantities of water. To determine its mechanical strength, a series of uniaxial compressive strength tests were conducted on HWFSC specimens with different water-to-solid ratios. Results indicat...

Characterizing the complicated flow behaviors arising from high water cut and low velocity oil-water flows is an important problem of significant challenge. We design a high-speed cycle motivation conductance sensor and carry out experiments for measuring the local flow information from different oil-in-water flow patterns. We first use multivariate time-frequency analysis to probe the typical ...

The implementation of oilfield development technology is closely related to geological conditions. Scientific and reasonable exploitation strategy great significance improve economic benefits technical utilization rate. At present, the in middle late stage, there are still many problems technology, which need be adjusted innovated urgently. According conditions oil fields current intensive it p...
