Abstract: Through the in-depth reading of the proposition of the Goldbach conjecture, the paper holds that the proof of the screening method is not in line with the meaning of the question, and thus puts forward the proof of the function method. In this paper, two independent linear prime functions of two variables p₁and p₂are constructed in the variable interval [1, 2m], and then two equivalent linear even functions of two variables N and 2m are logically deduced. The present study came to a consistent conclusion based on the qualitative and quantitative analysis of these two equivalent even functions: in the same definitive domain (greater than 2), the equations N = 2m must be established. From this, it is deduced that 2m=p₁+p₂ surely is set up.

Abstract: Guided by the principle of natural philosophy and combined with the gene knowledge of biological science, this paper makes an in-depth qualitative and quantitative analysis of the initial segment of prime infinite number sequence with gene significance. It is found that the percentages of prime infinite set and composite infinite set in odd number are 31.9% and 68.1% respectively. So the prime composite ratio of odd number is 31.9∶68.1. On the basis of this prime composite ratio, this paper makes a qualitative and quantitative analysis of the distribution of prime numbers in the infinite sequence of positive integers, and draws a logical conclusion about the infinity of twin prime numbers: in the infinite sequence of positive integers, for any twin prime point 6m (m ≥ 1, 6m-1 and 6m + 1 are prime numbers), there must be a twin prime point 6 (m + n) adjacent to 6m in the interval of 0 < n / m ≤ 1, Let 6 (m + n) - 1 and 6 (m + n) + 1 be prime numbers. Therefore, the existence of twin prime points must be infinite, and the average distance 6n of all twin prime points on the positive integer number axis is n < 5.

Abstract: In this paper, the performance of inverted pendulum has been Investigated using neural network control theory. The proposed controllers used in this paper are NARMA-L2 with Resilient backpropagation and Levenberg Marquardt backpropagation algorithm Controllers. The mathematical model of Inverted Pendulum on a Cart driving mechanism have been done successfully. Comparison of an inverted pendulum with NARMA-L2 with Resilient backpropagation and Levenberg Marquardt backpropagation algorithm Controllers for a control target deviation of an angle from vertical of the inverted pendulum using two input signals (step and random). The simulation result shows that the inverted pendulum with NARMA-L2 with Resilient backpropagation Controller to have a small rise time, settling time and percentage overshoot in the step response and having a good response in the random response too. Finally, the inverted pendulum with NARMA-L2 with Resilient backpropagation Controller shows the best performance in the overall simulation result.

Abstract: It is based on the relevance of ergonomic knowledge, skills and competences in the establishment of a new ergonomic learning environment in schools and the development of the present-day school teacher's ergonomic culture. In the ergonomics system, the training of educators and students to save labor, ensure the teacher's participation in the creation of a comfortable and effective, safe educational environment in the school has been considered.

Abstract: Diversification of the tourism industry, a comprehensive study of the tourist potential of certain geographical areas, the identification of periodic (seasonal) aspects, encourages the systematization of tourist types. Geography is a branch of science that studies the above features. Geographical tourism allows for the systematic development of its new species in order to comprehensively cover the tourist potential of a particular region.

Abstract: Okra is an economically important vegetable crop cultivated in the tropical and subtropical parts of the world. Advocacy for consumption of local vegetables like okra could help to enhance food security and combat malnutrition in developing countries. Okra is a multipurpose crop due to the various uses of its fresh leaves, buds, flowers, capsules, seeds and seeds. The focus of the study is to evaluate the antimicrobial effects of aqueous leaf extracts of V. amygdalina against post harvest bacterial associated with okra. Fresh leaves of the test plant were collected, air dried, and pulverized. Hundred grams of pulverized leaves of the test plant was mixed with 200ml of cold water a room temperature and left overnight. This was later filtered and the filtrate served as extract.  Five bacterial strains were isolated from the the okra viz: Bacillus subtilis, B. panthotenticus, B. cereus, Psedumonas chlororaphis, Aeromonas hydrophila. Agar well diffusion test method was used to determine the antibacterial capacity of the test plant. 20% aqueous extract of the test plant most inhibited Bacillus subtilis, Pseudomonas chlororaphis, Aeromonas hydrophila,  B. cereus and B. panthotenticus by 0.83, 1.65, 1.19, 1.51 and 1.43% respectively. It is shown from the result that higher concentrations of aqueous extract favoured higher inhibition of bacterial growth.

Abstract: Introduction: Personality of a brand is known as the core and the closest variable in customer’s decision to choose. Branding is a new phenomenon in the sector of health care services. This study aims to determine the relationship between branding and performance in Qa’em hospital of Mashhad city.  Study Method: The type of this study is correlation – cross sectional and has been carried out in the second half of 2008. Data on the created hotelling brands were collected by attending the hospital, interviewing authorities, observing the changes in study place, and studying performance indicators with the help of the statistics center of hospital and by studying the gathered materials. The data were analyzed using statistical software SPSS12 and Paires-Sample T-Test. Findings: No significant statistical relation was observed between branding and the mean value of variations in the number of patients (p= 0.453). There were significant statistical relations between the performed hotelling branding and variations in the mean value of bed occupancy percent (p= 0.000), bed circulation (p= 0.016), and emptiness ratio (p= 0.012). Discussion: Branding is effective in the improvement of hospital performance in the competitive environments in which they seek to attract selective patients.
