Based on the BECMP production line, this article introduced the main technological process for the production of BECMP pulp using aspen branch wood as the raw material. For better understanding of the new pulping method, Compared with the widely applied production line of P-RC APMP, the relevant pulping performances and operational efficiencies of BECMP were evaluated. The results showed that: using aspen branch wood in BECMP pulping was technically feasible, and it had more benefits as effective use of the lignocellulose raw material, energy saving, and reduction in water consumption. Most notably, the properties of the pulp met the requirements of APMP-based pulp mills, and simultaneously, its tensile strength was better than that of the APMP pulp.

Abstract For the purposes of simplifying the calculation task, adjusting production processes in time and solving the inconsistent requirements for carbon emissions, this paper investigates the calculation methods of carbon dioxide emissions from cement production, for example IPCC, WBCSD-CSI, MEE-CBMA, CNIS and BNU. Then a simplification and intuitive method is proposed. Based on the intuitive method, CO2 emission of 21 cement plants in China are calculated and analyzed, of which the error between the calculation results and those obtained by HJ 2519-2012 is less than 0.5%. About the carbon reduction technology in cement industry, there is limited reduction space that rely on energy efficiency improvements and clinker substitution. The technology of alternative fuels still needs to be further expanded. China has operated the first demonstration production line of CCUS technology at the Anhui Baimashan Conch cement plant with a capacity of 20,000 tons/year of industrial-grade liquid CO2 products and 30,000 tons/year of food-grade liquid CO2 products. Alternative raw material technology may be one developing direction to cut carbon emission; only 6.18% of steel slag was added to the raw meal at a 2500t/d production line, CO2 emission from process emissions were reduced by nearly 10%.

Making innovations to become competitive is not always an easy task, and in the industrial sphere, this thinking becomes even more complex. In this sense, proper use in raw material transformation processes becomes very challenging for managers, since improving processes is a condition where more can be done with less. Thus, many organizations seek to develop improvements through existing activities using a variety of techniques that are addressed in the literature, such as value flow mapping, lean production, simulations, among others. Therefore, this article aims to study and apply the computational simulation, through the use of Tecnomatix Plant Simulation © software, to obtain the best relation between financial return and productivity of a upholstery production line. In the methodology of this work was carried out the structural proposition of five scenarios. For the construction of these, a current scenario of the production line was carried out and for each new scenario, operators were added with new tasks to be performed. Although the final results show a better financial return for scenario three, the results obtained in scenario five are significant in terms of productivity indicators, although the cost with extra operators is much higher than in the other scenarios. Thus, it was clear the relevance of applying simulation in the production line, since the model assisted the managers in the decision making.

Unplanned outage of extensive transport and handling equipment used between main stages of the production process has magnified negative effect on logistics of the entire company. Article introduces information about examining and assessing the level of wear of working oil charge in an extensive hydraulic system of device used for the transport and processing of wood raw material between the woodworking line aggregates. The decisive role in preventing the listed unsolicited situation has respecting the early tribodiagnostic signal through the analytical ferrography. Completion of this particle analysis by information complex from other appropriately selected diagnostic methodologies will be essential for the trend analysis of wear regime of system oil charge creation. The analysis is also a key predictive information about state of degradation of internal contact surfaces of the examined machinery.

As the late processing of rice straw may consume the cost and pollute the environment, this paper put forward a method to use the rice straw, namely, the rice straw is used as the raw material for making seedling trays. The process of seedling tray production was designed, and the method of obtaining raw materials and steps of seedling tray production were introduced. In addition, the overall structure, transmission system and the forming mold of the pneumatic molding machine were also designed and produced. Next, the seedling trays were made by using the production line to analyze the characteristics of the rice straw seedling strays. The study was intended to explore the rules about the influence of moisture content on the characteristics of the seedling strays. As the moisture content of the seedling trays increased, the seedling trays expanded, increasing the volume, density and mass. However, the ultimate tension and shear force borne by the seedling stray decreased along with the increase of moisture content. It could be known from the analysis that: rice straw seedling trays could satisfy the needs of rice nursery. Compared with the traditional plastic seedling tray, the rice straw seedling tray can simplify the production process and provide natural nutrients for rice seedlings.

The content and structure of mental representation of economic crises were studied and the flexibility of the structure in different social contexts was tested. Italian and Swiss samples (Total N = 98) were compared with respect to their judgments as to how a series of concrete examples of events representing abstract indicators were relevant symptoms of economic crisis. Mental representations were derived using a cluster procedure. Results showed that the relevance of the indicators varied as a function of national context. The growth of unemployment was judged to be by far the most important symptom of an economic crisis but the Swiss sample judged bankruptcies as more symptomatic than Italians who considered inflation, raw material prices and external accounts to be more relevant. A different clustering structure was found for the two samples: the locations of unemployment and gross domestic production indicators were the main differences in representations.
