Manufacturing system, with high level of complexity and with a mix of semi-repetitive and repetitive products, to become productive, should seek the standardization of products and processes to obtain the optimization of use of production resources. However, it is necessary to measure the productivity, so that the system of measurement and control of manufacturing processes are an element critical as to ensure greater visibility of the flow＇s restrictions, minimized when detected properly. In this case, the automation of factory＇s measurement process can effectively contribute to ensuring the effectiveness of the function control of a manufacturing system. It is important to consider that the automation of the system of measurement and control of manufacturing processes, of complex environment, is heavily dependent of IT tools applied directly in the interface computational between the operation systems and the corporate systems. This heavy reliance, if exploited technically properly, allows that automation of the system of measurement and control of production makes the access to time real of availability of manufacturing process＇s data, such as processing time and setup time that it can export to a specialist software in programming production, for example, feasible. In this paper, the automation of the system of measurement and control of production is approached, in order to identify the main possibilities of the design of an information system capable to integrate the flow of information in an environment internal on manufacturing organizations, with emphasis in the digital manufacturing paradigm.

Computerized geochemical modeling of burial diagenesis of the Eocene turbidite reservoir elements：Urucutuca Formation,Espirito Santo Basin,southeastern Brazil passive margin

The computerized geochemical modeling, a useful tool to understand the diagenetic processes influencing the quality of hydrocarbon reservoirs, is performed by using different modules of computer codes based on the thermodynamic and chemical kinetic principles and their associated parameters. As observed in the reservoir lithofacies deposited from the marine sediment-gravity flows, a case study of diagenesis is presented here from the Espírito Santo Basin in southeastern Brazil. The study uses the Geochemist＇s Workbench（GWB～（TM））, PHREEQC～（TM） and TOUGHREACT～（TM） computation packages. The comparison of performances of these packages demonstrates the convergence of results from the software-based geochemical modeling with the petrographic observation of dissolution, albitization, kaolinization, and the precipitation of calcite and dolomite. Moreover, with limited data points, e.g., the sedimentary petrographic data acquired from limited number of boreholes, the computer simulation establishes itself to be a powerful quantitative method estimating the degree and type of diagenetic alteration of turbidite reservoir bodies in contact with a source of saline-water influx associated with salt ***, using the limited petrographic data points, the geochemical computer-simulation method can even be utilized and extrapolated for areas where similar geological context is interpreted but no borehole data are available. Hence, porosity of turbidite reservoir lithofacies can be predicted in relation to the spatial distribution of dissolution, kaolinization, and albitization of feldspars and authigenic carbonate precipitation.

Clinical significance of donor-specific human leukocyte antigen antibodies in liver transplantation

引用

World Journal of Gastroenterology 2015年第39期21卷 11016-11026页

作者： antonio Cuadrado David San Segundo marcos López-Hoyos Javier Crespo Emilio Fábrega Gastro- enterology and Hepatology Unit Marqués de Valdecilla University Hospital Instituto de Investigación Marqués de Valdecilla Immunology Unit Marqués de Valdecilla University Hospital.

Antibody-mediated rejection(AMR) caused by donorspecific anti-human leukocyte antigen antibodies(DSA) is widely accepted to be a risk factor for decreased graft survival after kidney transplantation. This entity also plays a pathogenic role in other solid organ transplants as it appears to be an increasingly common cause of heart graft dysfunction and an emerging issue in lung transplantation. In contrast, the liver appears relatively resistant to DSA-mediated injury. This "immune-tolerance" liver property has been sustained by a low rate of liver graft loss in patients with preformed DSA and by the intrinsic liver characteristics that favor the absorption and elimination of DSA; however, alloantibody-mediated adverse consequences are increasingly being recognized, and several cases of acute AMR after ABO-compatible liver transplant(LT) have been reported. Furthermore, the availability of new solid-phase assays, allowing the detection of low titers of DSA and the refinement of objective diagnostic criteria for AMR in solid organ transplants and particularly in LT, have improved the recognition and management of this entity. A cost-effective strategy of DSA monitoring, avoidance of class Ⅱ human leukocyte antigen mismatching, judicious immunosuppression attached to a higher level of clinical suspicion of AMR, particularly in cases unresponsive to conventional antirejection therapy, can allow a rational approach to this threat.

Oxidative stress is a common condition suffered by biological systems in aerobic conditions. Human semen also has its own molecular guard against the free radicals created by normal respiratory process or from immune reactions. The equilibrium of the creation and scavenging of free radicals is mandatory in the spermatozoa to fertilize and initiate a full-term pregnancy. The paper is a systematic review of publications that evaluate oxidative stress in semen. The Cochrane Library, Medline (1966-2003), Embase (1988-2003), SciSearch (1981-2003) and the conference papers were searched. When sperm samples from fertile and infertile males were analyzed, some of the mechanisms that determine the oxidative stress level were found to be impaired while others were unaltered. In conclusion, the literature as a whole provides contradictory findings and it is necessary to carry out more work to identify all the enzymatic and non-enzymatic systems involved in oxidative stress in the ejaculate, in order to develop new diagnostic systems and therapeutic strategies for combating detrimental free radical imbalance in the semen.

The focus of this paper is the design and use of a simple device to determine sediment yield from gullies. The simplicity and low cost makes this device especially useful when resources are limited. In this study, it was used to measure sediment yield at a site called An?o Gully, in a study area in Cáceres municipality (15o 57’ S and 57o 31’ W, Mato Grosso State, Brazil). This gully is located 28 kilometres from the center of the town, Cáceres, and was easy to reach during and immediately after storm events to make measurements with this device.

Assessment and Guidelines to Improve Eco-efficiency and Indoor Comfort at University of Passo Fundo, Brazil

引用

Journal of Civil Engineering and Architecture 2015年第2期9卷 179-187页

作者： marcos antonio Leite Frandoloso Luciana Londero Brandli Faculty of Engineering and Architecture University of Passo Fundo Passo Fundo 99052-900 Brazil

The paper deals with the energy and indoor comfort on buildings of UPF （University ofPasso Fundo）, located in southern Brazil, in order to improve the eco-efficiency concepts in the university＇s building stock, reinforcing its responsibility towards sustainable development. The factors that affect thermal performance and the energy consumption of two case studies were identified, including the general characteristics of the envelope and the indoor conditions. The simulations with DesignBuilder software compare the energy and thermal performance of both cases： those results allow the identification of their positive and negative aspects, as well as making a co-relation with the students＇ sensations of comfort--obtained through PMV （predicted mean vote）. The research indicates that it will be possible to improve eco-efficiency of existing and new buildings and campuses by retrofitting and upgrading it with regard to better indoor conditions that really correspond to climate conditions （hot and humid summers, and cold and damp winters）, using passive strategies for heating and cooling and at the same time to improve rational use of natural resources and to reduce the environmental impact. Probably, giving comfortable conditions to the users will increase energy consumption, but there is a potential reduction of lighting and equipment that could minimize this impact.
