The enzyme myo-inositol-1-phosphate synthase (MIPS EC 5.5.1.4) catalyzes the first step of myo-inositol biosynthesis, a product that plays crucial roles in plants as an osmoprotectant, transduction molecule, cell wall constituent and production of stress related molecule. Previous reports highlighted an important role of MIPS family genes in abiotic stresses particularly under salt stress tolerance...
A convenient and rapid HPLC method was developed for the determination of clinofibrate in human plasma using simple protein precipitation with the mixture of acetonitrile and 1M hydrochloric acid (95:5, v/v) followed by separation using an Inspire C 18 column with isocratic elution. The detection wavelength was 232nm and the flow rate was 1.0ml/min. The mobile phase consisted of acetonitrile...
When denoising with the method of Weickert's an isotropic diffusion equation, the textures and details will be compromised. A fidelity term is added into Weickert's equation. The coefficient of fidelity term will vary adaptively with the instant image, which makes that the diffusion term and the fidelity term come to a better compromise. Otherwise, when deciding the edge directions, because of the...
a secondary image denoising model based on the local energy operator is proposed. Since details and textures always will be compromised in the process of denoising, a local energy operator and a noise-texture operator are proposed. Combined with Weickert's coherence-enhancing model, the textures and details filtered by mistake during the process of denoising can be extracted as much as possible. After...
According to the basic law of energy conservation and conversion, the energy consumption evaluation indexes of two basic research objects in oil-gas gathering and transferring system, i.e. stations and pipelines, are established. On the basis of that, the energy consumption evaluation indexes for the whole system are obtained through mean weighted method. Then heat loss rate and pressure loss rate...
Temperature and pressure are important parameters related to energy consumption and safe operation of oil depot. A mathematical model is established from the point of temperature drop and pressure drop during storage and transportation process based on the reasonably simplified physical model of oil depot. Then parameter distributions of each node are obtained by the application of sequential modular...
