In order to analyze the intake flow characteristics of a four-valve direct injection(DI) diesel engine, the experiments and numerical simulations were conducted to investigate the flow coefficient, swirl ratio and intake flow interference of the following 4 combinations of intake ports: (1) helical (left) and tangential (right), abbreviation bar-va
In this Letter we study implications of the possible excess of 21-cm line global signal at the epoch of cosmic dawn on the evolutions of a class of dynamically interacting dark energy (IDE) models.We firstly summarize two dynamical mechanisms in which different background evolutions can exert considerable effects on the 21-cm line global signal.One
We discuss a possibility that the parameter space of the two Higgs doublet model is significantly narrowed down by considering the synergy between direct searches for additional Higgs bosons at the LHC and its luminosity upgraded operation and precision measurements of the Higgs boson properties at future electron-positron colliders such as the Int
The intensely fragrant flowers of the Rosa rugosa Thunb.have color lux blue conditioner been applied in medicine, and food and cosmetic industries.The species is cultivated for production of rose essential oil (Oleum Rosae) from its flowers.R.rugosa petals secrete the largest quantities of essential oil.The aim of the study was to identify the char
One of the trm atom knife most important issues in inventory control is determination of the reorder point.Defining parameters of this point are usually in forms of crisp or probability.In this article the parameters are considered as fuzzy numbers because of ambiguities in the real ssp218dda-sf world.Then reorder point value is calculated using a
