This study aims to quantitatively analyze and compute the velocity constant of three-compartment modeling, which is based on 13N-NH3 PET images of human brain tumors. We selected the parietal lobe, cerebellum, frontal lobe, and the average of these three reference regions to analyze the transfer constant...

All the acquisition of knowledge is a memory, the memory is the foundation of all intellectual activities. Memory is also the basis of education. This paper presents five neural pathways of memory, respectively, based on information, rules, concepts, expectations and integration. These pathways has important...

Pharmaceutics experiment is an important curriculum which acts as a bridge between Medical science, pharmacy theories and practice. In order to improve the teaching effect of experiment of pharmaceutics, this article discusses the characteristic of pharmaceutics experiment and told how to put the teaching...

Preparation of gold nanoparticles with a narrow size distribution has enormous importance in nanotechnology. Methanobactin (Mb) is a copper-binding small peptide that appears to function as an agent for Cu sequestration and uptake in methanotrophs. Mb can also bind and catalytically reduce Au (III) to...

Hardwood dissolving pulp was used as the raw material for the preparation of cellulose nanocrytals (CNC) by sulfuric acid hydrolysis. CNC was added into the solutions of Polyvinyl alcohol (PVA) to prepared PVA/CNC blend films. The miscibility of PVA/CNC films were studied by X-ray diffraction (XRD) and...

The Drosophila U-shaped (ush) gene play important role in hemocyte differentiation. However, the mechanism of how the ush gene is mediated is still unclear. In this study, we reveals that ush gene expression increased during molting and metamorphosis stage of the third instar larva, 20-hydroxyecdysone...

A simulation system of the aviation autopilot for teaching and training is established. By analyzing the function, structure and principle of the aviation autopilot, the aviation autopilot simulation system is established to realize the real-time control of flight environment. The simulation system mainly...

By predicting the propagation of Ebola, we can find a better way to control the spread of the virus. Unlike traditional SIR model, we consider the patients under incubation period and antibody carriers after cure in our model. To begin with, we apply five classifications to sample individuals (i.e. the...

A novel thiopyrano[4,3-d]pyrimidin derivative bearing a indole-hydrazone was synthesized and structure was confirmed by 1H NMR and MS. Moreover, this compound was evaluated for its cytotoxicity against the H460 cell lines and inhibitory activity against mTOR kinase at a concentration of 10uM. The result...

A novel thiopyrano[4,3-d]pyrimidine derivative compound 1 was synthesized with methyl dimethyl 3,3'-thiodipropionate as starting material through five steps, including cyclization, chlorination, substitution with morpholine and coupling with 5-bromopyridin-2-amine through Suzuki reaction. And its structure...

As the airborne air conditioner suffers from the variance of nature of the material, structure features, loads applied and stochastic factors, the fatigue life of its structure tends to deviate from the designed life. Based on stochastic finite element method, a mathematic model of the reliability analysis...

In order to better control the spread of the disease, we should build a drug delivery system when the Ebola spread throughout the West Africa. We proposed that build up medical service centers to deliver drugs and vaccines to isolated regions. According to graph theory, the minimum number of the centers...

Microwave irradiation provided an effective tool for rapid, clean, and high-yielding transformations of organic reactions. Despite these advances, the N-alkylation of amines with alcohols under microwave irradiation remains less unexplored. We demonstrated a general and efficient method for the synthesis...

Teaching contents, teaching methods and means, teaching characteristics, among others are discussed hereby for soil fertilizer science courses of horticulture in Shenyang Agriculture University. Summary and experience are available for soil fertilizer science course in terms of developing students’ interest...

Sustainable development evaluation is an important theme in sustainable development research. Aim to acurratly measure the sustainability of a country, this paper constructs the comprehensive evaluation system of sustainable development for a country using the Support Vector Machine(SVM) and Principle...

According to the characteristics of transient zero sequence components as well as the existing information fusion technology has the disadvantage of high sample dimension and computer overhead in fault line selection in small current grounding fault . First of all, by using the empirical mode decomposition...

The Drosophila TATA-box binding protein (TBP) is a general transcription factor required by all three eukaryotic nuclear RNA polymerases, it can recognize the TATA-box sequence to initiate gene transcription. TBP and other TATA binding factors are spatio-temporal control of gene expression in different...

IMolodtsov first proposed the soft set theory, which can be utilized as a general mathematical tool for dealing with fuzzy and uncertain information. As a generalization of soft set, intuitionistic fuzzy soft set is another soft set structure, it is a combination of an interval-valued fuzzy set and a...

Urinary calculi shall afflict people for decades. People invented many devices for treatment of calculi. Extracorporeal shock wave lithotripsy because of its relative safety, less trauma, low cost, good treatment effect, has soon become a preferred method in the treatment of urinary calculi. With the...

Because the output of solar panels is influenced by external environment easily, and in order to ensure the energy generated by solar panel can be used as much as possible, so the maximum power point tracking technology is particularly important. In this paper, to achieve the maximum power point tracking...
