Studying drug relationships can provide deeper information for the construction and maintenance of biomedical databases and provide more important references for disease treatment and drug development. The research model has expanded from the previous focus on a certain drug to the systematic analysis of the pharmaceutical network formed between drugs. Network model is suitable for the study of the nonlinear relationship of the pharmaceutical relationship by modeling the data learning. Association rule mining is used to find the potential correlations between the various sets of massive data. Therefore, based on the network model, this research proposed an algorithm for drug interaction under improved association rules, which achieved accurate analysis and decision-making of drug relationship. Meanwhile, this research applied the established association rule algorithm to discuss the relationship between Chinese medicine and mental illness medicine and conducted the algorithm research and simulation analysis of the association relationship. The results showed the association rule algorithm based on the network model constructed was better than other association algorithms. It had reliability and superiority in decision-making in improving the drug-drug relationship. It also promoted the rational use of medicines and played a guiding role in pharmaceutical research. This provides scientific research personnel with research basis and research ideas for disease-related diagnosis.

As a result of some unexpected facts observed during an investigation on the etching properties of the carbides in alloy steels, the study of the changes which are well known to occur in iron carbide was commenced. Since pure iron carbide was not to be obtained in bulk, the material used Was a Swedish white pig iron which contained about 60 per cent. Fe 3 C. The remainder consisted of more or less pure iron, and in view of the complexity of the curves expressing the relationship of the electrical resistance to temperature it was necessary to add to the high carbon material as pure a sample of iron as could be obtained. This was a remarkably pure sample of American ingot iron containing 99⋅9 per cent. iron. To link up these two materials, two steels with about 0⋅15 and 1 per cent, of carbon were also examined. The full analyses of the materials used are recorded in Table I. It is now well known that carbide of iron, Fe 3 C, has a change point at about 200°C., but the fact that there are also equally important changes in pure iron has not, hitherto, been clearly realised, although there have, from time to time, been found values for various physical and mechanical properties which did not fit well on curves showing the general relationship of the property and temperature.

A number of hypotheses have been proposed to explain the mechanisms that promote coexistence among sympatric rodents in North American deserts. In an effort to determine how the distribution of seeds influences foraging patterns and coexistence in a three-species community of heteromyid rodents, we developed a computer simulation model that determines the efficiency of foraging for animals of different sizes. Specifically, the simulation determines how long it would take a forager to gather sufficient energy for 24 h if the animal stopped at seed patches of certain densities. The analyses were conducted for naturally occurring seed distributions and densities, for simulated normal and uniform distributions at natural densities, and for natural distributions at seed densities one-third those known to occur naturally. The results indicate that, under natural distributions and densities, each of the three species possessed unique optima for utilising seed patches of different density. However, when either the seed distribution or density differed from actual values, all three species had identical optima. The implications of these results for promoting coexistence are discussed.

Computer simulation method is used to study the relations of airbag effect and occupant position. By changing the position of 50% dummy model to achieve the purpose of changing the position between airbag and occupant, three kinds of simulation test are made, and the simulation results are analyzed and compared. It is shown that between the belted occupant and airbag exists such a position or distance, at which the injury to occupant is the smallest when the traffic accident happens.

A new types of hyperbranched polyester was synthesized by the 2,2-bis(hydroxymethyl) propionic acid as an AB2-type monomer and glycerol as the core moiety. Molecular weights were confirmed by Gel Permeation Chromatography. Acid values were titrated by KOH. The hydroxy value was obtained by titration. Furthermore, we calculate logarithmic value of acid value, hydroxy value, and molecular weight, respectively, and the simulation model curves were obtained. Based on the simulation model curves, we establish the empirical equation of the relationship of molecular weight, acid value and hydroxy value.

A collection of mobile nodes deployed with a temporary intention is called mobile ad hoc network (MANET). Every deployed node has the capable of connecting the network communication, and every node has the capable of configuring network communication. There are many routing procedures to discover the proper route from source to destination. The routing protocol helps to channelize the route from one point to other for establishment of the communication. This paper discusses the detailed and the elaborated study of the MANET security issues and the various routing protocols. Moreover, it describes about the OSI model with the relationship of security systems. The elaborated and the detailed approach of the various protocol helps to build a progressive idea of the MANET security. Various issues and the overcomes help to find the loopholes of the threats, and it clearly explains the analysis of the MANET efficiency. The simulation analysis helps to know the comparison analysis of various protocols.

Although many years of research have gone into the present knowledge of the forming and shaping of metals, most of our capability of making components in ferrous materials goes back to the days of craft and skill. The major expenditure on fundamental studies in metal working has been effective only in refining existing processes rather than leading to new ways of manufacture. A better understanding of the relationship of material properties to stress and deformation modes has had some influence on process developments. Much more is owed to developments in the size of plant units, economic, production engineering, marketing and managerial factors. The more recent developments and trends in secondary manufacturing processes are reviewed.

In this paper we intend to address the contentious issue of history as Marx process. Our main thesis is that Marx poses a plurality of solutions to bring the future of the process that aims both to break and overcome capitalism. Hence we say that there is no unified on the issue but rather a hierarchy of solutions depending on the immanence of the capitalist production process criteria. The more remote the solution is found regarding the production process have less value for the sense of modern history and vice versa. To defend this thesis, we have structured the work into three parts. A first part where we present a philosophical interpretation of the origin of the process and its conditions grasp: by way of will and by way of the story. A second that aims to show the different conceptions of process limit: as severe political boundary as tendential law that measures accumulation and profit. A third where we explicit the properly dialectical content of Marx’s theory of surplus value. And finally, some final considerations in which we conclude that the dialectic ends bringing order to the pluralism of solutions presented by Marx especially if you consider a “Aufhebung” as overcoming the economic contractualism to end the relationship of labor to capital.
