The Tourist Harassment Based on the Marketing  [PDF]
Ji Wen, Yina Li
American Journal of Industrial and Business Management (AJIBM) , 2015, DOI: 10.4236/ajibm.2015.53012
Abstract: The marketing innovation includes not only the innovation of production quality, but also the innovation of service. According to the foreign literatures and the past solution of tourist harassment, this paper emphasizes the importance of tourist harassment. “No harassment” can be a bright spot of destination marketing. The purpose of this paper is to propose a new and novel solution for destination marketing in a different prospect. The situation without production innovation can be promoted by the idea of traveling with no harassment.
Research advances in the relationship between prolactin and spontaneous abortion

Zhong Xi Yi Jie He Xue Bao , 2012,
Abstract: ABSTRACT: Spontaneous abortion is one of the most common gestational conditions, with the morbidity of 1% to 5% in married women. It is a serious problem troubling women at the reproductive age. There are many factors causing spontaneous abortion, among them, spontaneous abortion resulting from endocrine abnormalities can be detected and treated. Prolactin is a major endocrine hormone participating in reproductive regulation and playing an important role in early pregnancy implantation and pregnancy maintenance. When there are unusual levels it is closely related to spontaneous abortion, leading to a necessity to further study the relationship between them. International and domestic research developments in recent years about the correlation between prolactin and spontaneous abortion are discussed in this paper.
Prime Graphs and Exponential Composition of Species

Mathematics , 2007,
Abstract: In this paper, we enumerate prime graphs with respect to the Cartesian multiplication of graphs. We use the unique factorization of a connected graph into the product of prime graphs given by Sabidussi to find explicit formulas for labeled and unlabeled prime graphs. In the case of species, we construct the exponential composition of species based on the arithmetic product of species of Maia and M\'endez and the quotient species, and express the species of connected graphs as the exponential composition of the species of prime graphs.
The Research of Examination Paper Generation Based on Index System Metrics and Multi-Objective Strategy  [PDF]
Yan Li, Ji-Qiang Tang
Journal of Software Engineering and Applications (JSEA) , 2012, DOI: 10.4236/jsea.2012.58073
Abstract: Since the examination paper generated with computer by the algorithms of random and backtracking takes on inferior quality and inefficient, and the question of generating examination paper with computer has the character of multi-ob-jective because of the index system metrics, the genetic algorithm with multi-objective strategy optimization is proposed to solve this problem. Mapping the index system to multi-objective functions and optimizing the computing with multi-objective strategy are employed in the algorithm. The genetic algorithm experiment based on the multi-objective strategy optimization shows that the result has the advantages getting tradeoff between performance and quality, and having the ability to tune the performance and quality to meet the user’s requirements.
Vitamin E Therapy in Non-Alcoholic Fatty Liver Disease  [PDF]
Xiangbing Shu, Li Zhang, Guang Ji
International Journal of Clinical Medicine (IJCM) , 2014, DOI: 10.4236/ijcm.2014.53016
Abstract:


Non-alcoholic fatty liver disease (NAFLD) is closely related to oxidative stress. Vitamin E (VE) is an effective antioxidant, which could relieve NAFLD symptoms by improving the balance of oxidation and anti-oxidation. However, recent researches indicate that the functional mechanisms of VE are not only limited to anti-oxidation, but also include adjusting the metabolism disorders of glucose and lipid. Furthermore, the efficacy of VE remains controversial in the treatment of NAFLD by far, and the suitable condition of patient, drug dosage, drug safety and course of treatment during clinical application still need to be discussed. Therefore, this paper reviewed the recent study progresses of clinical application of VE alone and VE and other drugs.


Aerodynamic Design of the Bleed Slot in a Hypersonic Quiet Nozzle  [PDF]
Ruiqu Li, Junmou Shen, Feng Ji
Journal of Applied Mathematics and Physics (JAMP) , 2014, DOI: 10.4236/jamp.2014.26053
Abstract:

The bleed slot is necessary for the requirement of the hypersonic quiet flow all over the world. The aim of the bleed slot is to decrease the influence of the disturbances from the contraction of the quiet nozzle to the boundary layer downstream of the throat, so that the boundary layer of the nozzle could be maintained as laminar flow. The main parameters of the bleed slot include the distance from lip to throat (DLT) and the width of slot (WS). Various values of those parameters will affect the performance of the slot by changing the suction intensity of the bleed slot. Two kinds of the bleed slots in the world are compared in this paper and the aerodynamic design of the bleed slots is optimized based on the Purdue-type slot. The influences of the various values of those parameters to the flow field around the throat are analyzed and the optimizing results of DLT and WS are consistent with those relative data designed for the slot of the Boeing/AFOSR Ma 6 Quiet Tunnel.

Preparation of Electrode of Copper-Nickel Composite Material and Its Capacitance Performance  [PDF]
Xiuxia Zhang, Chaohui Li, Qianyu Ji
World Journal of Nano Science and Engineering (WJNSE) , 2016, DOI: 10.4236/wjnse.2016.64015
Abstract: Nickel oxide/copper oxide composites are prepared. Then the composites were transferred into autoclave and thermal sinter under different temperature and different time. As-prepared composites were analyzed by XRD, and it was concluded that with the increase of hydrothermal time, content of NiO and Ni0.75Cu0.25O increases, but particles become smaller; it would improve the electrochemical activity. By SEM images directed lower crystallinity of composites, deeper porosity and rougher surface would have better electrochemical activity. The electrochemical performance was investigated by cyclic voltametry, AC impedance and galvanostatic charge-discharge. All results show that under the condition of 150°C 30 h, the electrochemical performance is the best. The specific capacitance was 225.67 F·g-1 at the charge-discharge current of 1 A·g-1.
Ordinal Semi On-Line Scheduling for Jobs with Arbitrary Release Times on Identical Parallel Machines  [PDF]
Sai Ji, Rongheng Li, Yunxia Zhou
Intelligent Information Management (IIM) , 2017, DOI: 10.4236/iim.2017.96014
Abstract: In this paper, we investigate the problem of semi-on-line scheduling n jobs on m identical parallel machines under the assumption that the ordering of the jobs by processing time is known and the jobs have arbitrary release times. Our aim is to minimize the maximum completion time. An ordinal algorithm is investigated and its worst case ratio is analyzed.
Analysis on the Nutrition Composition and Antioxidant Activity of Different Types of Sweet Potato Cultivars  [PDF]
Hua Ji, Haixin Zhang, Hongtao Li, Yunchao Li
Food and Nutrition Sciences (FNS) , 2015, DOI: 10.4236/fns.2015.61017
Abstract: In this study, we selected four different color fleshed sweet potatoes, purple- (Jizi 01), red- (Xinong 431), yellow- (Beijing 553) and white- (Shangshu 19) fleshed cultivars as test materials, analyzed nutrient composition, dietary fiber content, anthocyanins quantification, and total phenolics content, and also measured their total antioxidant activity in four different types of sweet potato. In view of differences in flesh color, the nutrient contents of different cultivars appeared to be significantly different. Starch contents of Beijing 553 and Shangshu 19 were higher, but fat contents were lower than others. Protein content of Shangshu 19 was the highest followed by Jizi 01 and Xinong 431. In addition, our analysis results confirmed that purple fleshed sweet potato possesses much higher anthocyanins content than others, even up to 6.23 mg/g dry matter. Also, dietary fiber, total phenolics content, and total antioxidant capacity of Jizi 01 were significantly higher.
