Heap bioleaching is an established technology for recovering copper from low-grade sulphide ores. Recently, genetics-based approaches have been employed to characterize mineral-processing bacteria. In these approaches, data analysis is a key issue. Consequently, it is of fundamental importance to provide adequate mathematical models and statistical tools to draw reliable conclusions. The present work relates to current studies of the consortium of organisms inhabiting the bioleaching heap of the Escondida mine in Northern Chile. These studies aim to describe and understand the relationship between the dynamics of the community and the performance of the industrial process. Here, we consider a series of quantitative real-time polymerase chain reaction (PCR) experiments performed to quantify six different microorganisms at various stages of the bioleaching cycle. Establishing the reliability of the data obtained by real-time PCR requires the estimation of the error variance at several different levels. The results obtained show that the sampling component of the error variance is the dominant source of variability for most microorganisms. An estimate for the proportional reduction in residual standard deviation from the use of extraction and real-time PCR triplicates was found to range from 3% to 27% for the different organisms. This result suggests that triplicate assays would produce only a modest reduction in error variance compared to more frequent sampling from the heap.

This paper used 586 survey data of aquaculturists in the Shandong and Zhejiang provinces of China and built two intermediary effect models by incorporating fishery cooperative support, order fisheries participation, product quality certification, and safety factor input behavior into the same theoretical analysis framework in order to verify the direct influence of fishery cooperative support on safety factor input behavior of aquaculturists, as well as the intermediary effect of order fisheries participation and product quality certification in the relationship between fishery cooperative support and safety factor input behavior of aquaculturists. The research concluded that fishery cooperative support has a significant positive influence on safety factor input behavior. Participation in order fisheries and product quality certification have a partial intermediary effect in the relationship between fishery cooperative support and safety factor input behavior of aquaculturists; their intermediary effect accounts for 10.3% and 33.7% of the total effect. The research conclusions can provide reference and suggestions for China’s fisheries to better carry out green aquaculture.

The aim of this paper is to discuss the company’s maturity level in the view of process management. As part of the discussion, there were made three study cases with the following characteristics: in large sized (company A) works in the field of toys with 350 employees; in medium sized (company B) that operates in the Amusement and leisure-industry technology with 80 employees and in midsize sized (company C) acts in the garment sector with 148 employees. In these study cases using as assessment tool the Maturity Model or the Rohloff Method, aiming at researching the management of the organization, methods, documentation, training, performance and portfolio of processes as well as the relationship between social networking and the multifunctional teams involved in the process, as the process owner, sponsors and facilitators. With the purpose of deepening the understanding of the processes for a period of three years, the researchers conducted systemic visits to the chosen companies, making on-site survey, observing the process, its characteristics and peculiarities. From the result it was possible to establish the correlation between the level of documentation of the companies and their levels of maturity on process management.

Purpose: The purpose of this paper is to analyze the PDP (Product Development Process) maturity level in the food industry to identify the compatibility status of their quality certification and their maturity level.Design/methodology/approach: A bibliographical review was conducted about product development, maturity process, and Capability Maturity Model Integration (CMMI). An adapted method from CMMI was used, which allows evaluating the level of maturity, through a semi-structured questionnaire. The questionnaires were applied in five companies of this industry and then, an analysis of the information obtained in each company was carried out and compared, aiming to understand the sector maturity.Findings: After conducting the interviews in each company, the median of each group of questions was calculated, according to the methodology described. Data collected from this sector show consistency between certification time and maturity level. Research limitations/implications: Due to the low number of respondents, this data cannot be generalized to this sector, being considered only an indication of the situation of the food industry located in Curitiba region. Practical implications: This study shows the relationship between the maturity level of food industry and ISO 9001 quality certification. The study shows that for the company to obtain an ISO certification, it must have been at least maturity level 2, highlighting, as well, the main deficiencies of this sector. Originality/value: The original value is to show the relationship between the maturity level of food industry and ISO 9001 quality certification.

The purpose of this study is to explore the relationship between solar orientation, age (constructive characterization) and energy performance of Portuguese residential building stock and to assess the usefulness of exploring the Portuguese National System for Energy and Indoor Air Quality Certification of Buildings (SCE) database through multivariate analysis techniques. By using principal components technique, it was possible to condense the residential units’ features to only four principal components (PC): solar orientation; constructive characterization; geometry and energy performance, making information more workable. Grouping the entities into Clusters with favourable and unfavourable solar orientation and old buildings allowed to dilute the particularities of each entity, facilitating the interpretation of the data through generalization. A regression model was generated in order to explore/confirm which factors influence summer comfort the most. Using this approach, it was illustrated that the exploration of the SCE database through multivariate data analyses has an enormous potential to convert data into knowledge.

A review is given of information on the galactic-centre region obtained from recent observations of the 21-cm line from neutral hydrogen, the 18-cm group of OH lines, a hydrogen recombination line at 6 cm wavelength, and the continuum emission from ionized hydrogen.Both inward and outward motions are important in this region, in addition to rotation. Several types of observation indicate the presence of material in features inclined to the galactic plane. The relationship between the H and OH concentrations is not yet clear, but a rough picture of the central region can be proposed.

Biologic Factors

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

Abstract This commentary focuses upon the relationship between two themes in the target article: the ways in which a Markov blanket may be defined and the role of precision and salience in mediating the interactions between what is internal and external to a system. These each rest upon the different perspectives we might take while “choosing” a Markov blanket.
