Alarm root-cause analysis and alarm prioritization are good for alarm flood reduction. This paper proposes a systematic rationalization method for multivariate correlated alarms to realize the root cause analysis and alarm prioritization. An information fusion based interpretive structural model is constructed according to the data-driven partial correlation coefficient calculation and process knowledge modification. This hierarchical multi-layer model is helpful in abnormality propagation path identification and root-cause analysis. Revised Likert scale method is adopted to determine the alarm priority and reduce the blindness of alarm handling. As a case study, the Tennessee Eastman process is utilized to show the effectiveness and validity of proposed approach. Alarm system performance comparison shows that our rationalization methodology can reduce the alarm flood to some extent and improve the performance.展开更多

Three experiments were included in this investigation: (1) First experiment was a bioassay related to the germination performance, shoot and root development of corn (Zea mays L.) and peanut (Arachishypogaea) at two concentrations of root (3% and 1.5%) and shoot (12% and 6%) aqueous extracts of corn medium; (2) The second experiment dedicated to the intercropping of corn and peanut at four treatments; (3) While the third experiment involved the effect of peanut root exudation on growth of corn. Experiment results revealed that corn shoot and root water extracts highly inhibited seed germination of both corn and peanut, the inhibitory of shoot extract was more than root aqueous extract. While its effect on the seedling growth was vice versa as compared with control treatment, there was an increase in root and shoot length of both corn and peanut when grown in corn aqueous extracts. Intercropping experiment results has stimulated most traits of peanut under studying. Also for corn, there was apparent and significant increase in all characteristics as compared with control. It was further confirmed from the results of peanut root exudates that had all studied characters of corn were stimulated than the control treatment.展开更多

Competitiveness is the most important internal factor to determine a country's export performance. This factor is referenced constantly and it is considered as a necessary condition when it comes to staying in foreign markets, gaining new ones, and increasing the share of exports. This paper is a preliminary study that aims to develop a software tool which is able to characterize the competitiveness of Argentina in the international market for fishery products. We propose to use predicates generated from the knowledge of experts in the study area and evaluate them through Compensatory Fuzzy Logic. The predicates were related to obtain a value that quantifies the competitiveness of Argentina in the various markets in which it provides. The analysis of results verifies the consistency of the computer tool developed. This methodology applied to the fishing industry is an innovative approach to Argentina, not only for the sector in question but also for other industrial sectors that make up the country's productive system展开更多

Keeping in view the importance of amylose for various food industries as well as its importance on domestic level, the current study was conducted to analyze the amylose content of common cereals e. g rice (sela, coarse and basmati), maize yellow, Kisan and Azam varieties and wheat (Tatara, Fakhr-e-sarhad and Bakhtawar-92) varieties as well as quantifying the influence of cooking/boiling procedures on the amylose contents of cereals. The maximum amylose content were observed for wheat variety Tatara (24.28%) followed by Bakhtawar-92 (22.74%) and Fakhr-e-sarhad (19.77%). Among maize and rice varieties studied, Kisan and course rice were rich in amylose content with values of 27.19 and 30.48% respectively. The chapti of Tatra wheat were scored highest for appearance (7.6), flavor (7.5), texture (7.6) and overall acceptability (7.55). The roti of Kisan and Azam varieties got maximum appearance score of 7.6 as compared to 7.4 for maize yellow variety. Basmati rice was scored highest regarding appearance (8.4), flavor (8.6), texture (8.6) and overall acceptability (8.53. The moisture content ranged from 10.61 (Azam) to 8.01% (wheat variety Fakhr-e-sarhad). Cooking reduced the amylose content of wheat bread from (19.77%-24.28%) to (15.47%-15.94%) with cooking time of 5 min, maize bread from (21.48%-27.19%) to (19.53 %-25.85%) with maximum cooking time of 10 min and boiled rice from (24.90%-30.48%) to (24.18%-30.19%) with cooking time ranging from 12 to 20 min. It can be inferred from these studies that the reduction in amylose content were more in chapti/roti preparation of wheat and maize varieties as compared to boiling of rice varieties and that significant varietals differences exist in amylose content of the uncooked samples.展开更多

To understand these phenomena and problems, first the nitrogen cycle and the environment are described. Then recent trends for nitrogen cycling through the food and feed system, N2O emissions from fertilized upland and paddy soils, and NO-3 pollution in ground water in Japan are reported. Finally, mitigation strategies in Japan for reducing N2O emission and NO-3 pollution are proposed, including nitrification inhibitors, controlled release fertilizers, utilization of plant species that could suppress nitrification, utilizing the toposequence, government policy, and appropriate agricultural practices. Of all the technologies presented, use of nitrification inhibitors and controlled release fertilizers are deemed the most important with further development of these aspects of technologies being expected. These practices, if employed worldwide, could help reduce the load, or environmental deterioration, on the Earth's biosphere.展开更多

Wines from different areas in Mendoza (the most important producer of Malbec) were also included to test possible differences within this province. Ten key attributes were first recognized by descriptive analyses and then carefully evaluated by a trained sensory panel composed of 10 judges. Among the aroma and flavour attributes the analyses focused on plum, red fruits, white pepper, bell pepper, and floral. Three attributes of taste (acidity, astringency, and bitterness) and two attributes of color (red and blue-purple hues) were also analyzed. Statistical differences and similarities in sensory data were tested using analysis of variance (ANOVA), multiple means comparisons by least significant difference test (Fisher LSD), and principal component analysis (PCA). ANOVA and Fisher LSD tests of sensory data showed significant differences (P 〈 0.05) for 6 out of 10 wine attributes: plum, floral, red fruits, astringency, red and blue- purple hues.展开更多

B. variegata roots penetrated to a maximum depth of 4.78 m, whereas, M. alba roots were found down to 1.48 m depth. Lateral spread was minimum in B. variegata (1.10 m)and maximum inR. pseudoacacia (7.33 m). Maximum root biomass of 6.30 kg was found in R. pseudoacacia and minimum (2.43 kg) was found in M. alba. For four species viz.,G. optiva, M. alba, C. australis andR. pseudoacacia, 68%-87% root biomass occurred within top 0-30 cm soil depth, but forB. variegata this was only45%. The soil binding factor was maximum in G. optiva and minimum in B. variegata. Soil physico-chemical properties also showed wide variation. The study suggests thatB. variegata with a deep root system is the most suitable species for plantation under agroforestry systems. R. pseudoacacia and G. optiva with deep root systems, more lateral spread and high soil binding factor are suitable for plantation on degraded lands for soil conservation.展开更多

As a consequence, public institutions of science and technology have been called to play a central role in the innovation systems providing relevant inputs for the necessary learning process in order to obtain product and process innovation. Nevertheless, it looks like that these institutions, in Argentina, are prisoners of the offer (science) push--demand pull tension far away of a systemic behavior in an innovative environment. This work studies four cases of agrifood production in Argentina, considering a regional approach and the learning networks around each production. It is concluded that the behavior of each institution is different for each case. INTA has a systemic conduct in all cases while the other ones show a systemic behavior only in the case that their offer matches to specific demands.展开更多

Two levels of three independent variables--application of V, use of polyethylene cover (PC) on the soil. and soil depth (D)---on various dependent variables were studied. Vinasses favoured crop yield and reduced the number of Meloidogyne incognita juveniles in soil. The concentrations ofN. P and K increased with the interaction VxD, with PC also increasing N concentration. The amounts of humic acids and humin decreased with D; fulvic acid concentration increased with V, but decreased with the interaction VxPC. Soil physical factors were improved mainly with D and V. Aromaticity of humic acid-like fractions increased ~'itb V. In general, V showed significant effects mainly on the topsoil, suggesting low leaching risks. The results indicate that the levels of the independent factors improving a group of variables were not the same that those contributing to another group. Therefore, their best combination should be determined for each scenario to achieve optimum agroecological performance.展开更多
