Published: June 2018

This article describes results of a research about the editorial performance of Terræ Didatica (TD). It puts in evidence that the educational journal of the University of Campinas has been well accepted by the community. The research sought to evaluate whether the journal effectively acts as a dissemination tool of geoscientific knowledge. The instruments are Likert questionnaires and interviews with readers, authors, editors and editorial board members, aimed at measuring a series of aspects of interest for Geosciences teaching. The answers strongly support the effort of TD for disseminating high quality articles, both technical and didactic, as has been rightly done so far. The data shows the existence of a critical mass of researchers, teachers, students and other interested parties capable of actively promoting the dissemination of Geosciences in Brazilian society and even forming a recognizable community at the international level. It was suggested the journal to go beyond the context of public institutions of higher education.

Authors: Jianguo Wang , Ying Zhu 
Published: June 2018

Abstract
Aiming at the problems of low efficiency, low cost of time and space, This paper proposes an algorithm to update the association mining of the inverted index tree. The algorithm combines the inverted index technology with the tree structure. When the data in the database is continuously updated, it can scan only the newly added part of the database, without having to scan the original database to count the number of transaction items. The optimal threshold predicted by Newton’s interpolation formula is compared with this frequency to get frequent item sets. Then, the confidence level is calculated for the combinations of different item sets in frequent item sets, and the correlation rules are obtained, and the correlation analysis of the rules is carried out to obtain a more realistic association rule. The inverted index tree updating association mining algorithm was applied to the data analysis of geological hazards monitoring system. One year data record of rainfall, groundwater level, soil water content and topography data was selected as the experimental data set. Compared with the IUAR algorithm, it is found that the inverted index tree updating association mining algorithm has some improvements in memory consumption and efficiency. The experimental results show that When the minimum support of IUAR algorithm remains unchanged, the number of transaction records is the same as the amount of new data, and Inverted Index Tree Incremental Updating Association Mining Algorithm takes less than 2/5 of the IUAR algorithm. When the number of transaction records and the amount of new data remain unchanged and IUAR algorithm support changes, the Inverted Index Tree Incremental Updating Association Mining Algorithm memory consumption is much smaller than IUAR algorithm. In the process of experiment, according to the results of the Inverted Index Tree Incremental Updating Association Mining Algorithm, the association rules are obtained and the correlation is judged. The strong association rules are used to set the alarm threshold of the geological disaster monitoring system.

Published: June 2018

Abstract
In order to improve the accuracy of the proposed algorithm in collaborative filtering recommendation system, an Improved Pearson collaborative filtering (IP-CF) algorithm is proposed in this paper. The algorithm uses the user portrait, item characteristics and data of user behavior to compute the baseline predictors model. Instead of the traditional algorithm’s similarity calculation, the prediction model is used to improve the accuracy of the recommendation algorithm. Experimental results on Moivelens dataset show that the IP-CF algorithm significantly improves the accuracy of the recommended results, and the RMSE and MAE evaluation results are better than the traditional algorithms.

Published: June 2018

Abstract
We prepared a variety of nickel-aluminum complex hydroxides, investigated their physicochemical properties, and evaluated their ability to adsorb phosphate ions (the molar ratios of nickel to aluminum, 1:2, 1:1, 2:1, 3:1, and 4:1, are referred to as NA12, NA11, NA21, NA31, and NA41). NA12 and NA11 have amorphous structures; their specific surface areas and the concentration of associated hydroxyl groups were greater than those of other adsorbents. The number of phosphate ions adsorbed onto NA12 and NA11 was greater than that onto other adsorbents. These results indicated that the phosphate ion adsorption is related to the specific surface area and the amount of hydroxyl groups. The adsorption isotherm data, and the effects of contact time and pH on the adsorption were investigated; our results implied that both the Freundlich equation model and the pseudo-second-order kinetic model describe the adsorption of phosphate ions by NA11. We showed that phosphate ions adsorbed onto NA11 can be desorbed by sodium hydroxide solution at different concentrations and that NA11 could be reused for at least three repeated cycles of phosphate ion adsorption and desorption. This study illustrates that NA11 has the potential for practical application as an adsorbent for phosphate ions from wastewater.
La rationalité théologique chez Paul Ricœur
Authors: Quesada Rodríguez Francisco 
Published: June 2018

L’herméneutique phénoménologique de Paul Ricœur nous donne la possibilité de réfléchir sur le statut rationnel de la théologie et sur l’éthique chrétienne, dans la mesure où conjointement le langage et l’action peuvent constituer une science humaine qui parle de Dieu et de l’homme à un même niveau épistémologique. Une telle rationalité, d’après Ricœur, doit mettre en jeu une nouvelle théologie anthropologique, qui reformule et raconte la « sagesse pratique » de la théologie chrétienne dans le cadre de la raison contemporaine. Afin d’analyser cette rationalité théologique, nous prendrons pour base les Gifford Lectures de Ricœur publiés dans Soi-même comme un autre (1990) et Amour et Justice (2008), ouvrages considérés comme une synthèse de sa pensée philosophique, sans nous priver de faire aussi parfois un retour ou un détour par quelques idées contenues dans d’autres ouvrages.

Objective.Patients with eosinophilic granulomatosis with polyangiitis (EGPA) frequently experience relapses, which lead to cumulative organ damage. In this retrospective observational study, we aimed to reveal the risk factors for relapse in EGPA.Methods.A total of 188 Japanese patients with EGPA diagnosed between 1996 and 2015 were identified from medical records in 10 hospitals. The diagnosis was based on the American College of Rheumatology 1990 criteria or Lanham’s criteria. Baseline characteristics, treatments, asthma exacerbation, and relapses were evaluated by retrospective chart review.Results.The median followup period was 56 months. The median age at disease onset was 59.7 years. At the disease onset, 95.2% of the patients had a history of bronchial asthma and 44.7% were positive for antineutrophil cytoplasmic antibodies. The cumulative survival and relapse-free survival rates at 5 years were 89.6% and 64.0%, respectively. Multivariate analysis with 2 models, proportional hazards, and competing risk models, was performed to identify the factors associated with relapse. The proportional hazards model identified azathioprine (AZA) maintenance therapy and high eosinophil counts at onset as independent factors with lower relapse risks, and high immunoglobulin E (IgE) levels at onset as a risk factor for relapse. The competing risk model identified no statistically significant factors.Conclusion.Although potential benefit of AZA maintenance therapy in preventing relapse of EGPA was suggested by the proportional hazards model, there was a discrepancy in the results between the models. Eosinophil counts and IgE levels at onset were also identified as candidates of factors associated with relapse in EGPA.

Published: June 2018

AbstractThe QFix EncompassTM stereotactic radiosurgery (SRS) immobilization system consists of a thermoplastic mask that attaches to the couch insert to immobilize patients treated with intracranial SRS. This study evaluates the dosimetric impact and verifies a vendor provided treatment planning system (TPS) model in the Eclipse TPS. A thermoplastic mask was constructed for a Lucy 3D phantom, and was scanned with and without the EncompassTM system. Attenuation measurements were performed in the Lucy phantom with and without the insert using a pinpoint ion chamber for energies of 6xFFF, 10xFFF and 6X, with three field sizes (2 × 2, 4 × 4, and 6 × 6 cm2). The measurements were compared to two sets of calculations. The first set utilized the vendor provided Encompass TPS model (EncompassTPS), which consists of two structures: the Encompass and Encompass base structure. Three HU values for the Encompass (200, 300, 400) and Encompass Base (−600, −500, −400) structures were evaluated. The second set of calculations consists of the Encompass insert included in the external body contour (EncompassEXT) for dose calculation. The average measured percent attenuation in the posterior region of the insert ranged from 3.4%–3.8% for the 6xFFF beam, 2.9%–3.4% for the 10xFFF, and 3.3%–3.6% for the 6X beam. The maximum attenuation occurred at the region where the mask attaches to the insert, where attenuation up to 17% was measured for a 6xFFF beam. The difference between measured and calculated attenuation with either the EncompassEXT or EncompassTPS approach was within 0.5%. HU values in the EncompassTPS model that provided the best agreement with measurement was 400 for the Encompass structure and −400 for the Encompass base structure. Significant attenuation was observed at the area where the mask attaches to the insert. Larger differences can be observed when using few static beams compared to rotational treatment techniques.

AbstractRechargeable aqueous Zn‐based batteries, benefiting from their good reliability, low cost, high energy/power densities, and ecofriendliness, show great potential in energy storage systems. However, the poor cycling performance due to the formation of Zn dendrites greatly hinders their practical applications. In this work, a trilayer 3D CC‐ZnO@C‐Zn anode is obtained by in situ growing ZIFs (zeolitic‐imidazolate frameworks) derived ZnO@C core–shell nanorods on carbon cloth followed by Zn deposition, which exhibits excellent antidendrite performance. Using CC‐ZnO@C‐Zn as the anode and a branch‐like Co(CO3)0.5(OH)x·0.11H2O@CoMoO4 (CC‐CCH@CMO) as the cathode, a Zn–Co battery is rationally designed, displaying excellent energy/power densities (235 Wh kg−1, 12.6 kW kg−1) and remarkable cycling performance (71.1% after 5000 cycles). Impressively, when using a gel electrolyte, a highly customizable, fiber‐shaped flexible all‐solid‐state Zn–Co battery is assembled for the first time, which presents a high energy density of 4.6 mWh cm−3, peak power density of 0.42 W cm−3, and long durability (82% capacity retention after 1600 cycles) as well as excellent flexibility. The unique 3D electrode design in this study provides a novel approach to achieve high‐performance Zn‐based batteries, showing promising applications in flexible and portable energy‐storage systems.
Red blood cell adhesion to heme‐activated endothelial cells reflects clinical phenotype in sickle cell disease

Published: June 2018

AbstractIn sickle cell disease (SCD), ‘disease severity’ associates with increased RBC adhesion to quiescent endothelium, but the impact on activated endothelium is not known. Increased concentrations of free heme result from intravascular hemolysis in SCD. Heme is essential for aerobic metabolism and plays an important role in numerous biological processes. Excess free heme induces reactive oxygen species generation and endothelial activation, which are associated with cardiovascular disorders including atherosclerosis, hypertension, and thrombosis. Here, we utilized an endothelialized microfluidic platform (Endothelium‐on‐a‐chip) to assess adhesion of sickle hemoglobin‐containing red blood cells (HbS RBCs), from adults with homozygous SCD, to heme‐activated human endothelial cells (EC) in vitro. Confluent EC monolayers in microchannels were treated with pathophysiologically relevant levels of heme in order to simulate the highly hemolytic intravascular milieu seen in SCD. RBC adhesion to heme‐activated ECs varied from subject to subject, and was associated with plasma markers of hemolysis (LDH) and reticulocytosis, thereby linking those RBCs that are most likely to adhere with those that are most likely to hemolyze. These results re‐emphasize the critical contribution made by heterogeneous adhesive HbS RBCs to the pathophysiology of SCD. We found that adhesion of HbS RBCs to heme‐activated ECs varied amongst individuals in the study population, and associated with biomarkers of hemolysis and inflammation, age, and a recent history of transfusion. Importantly, the microfluidic approach described herein holds promise as a clinically feasible Endothelium‐on‐a‐chip platform with which to study complex heterocellular adhesive interactions in SCD.

ABSTRACTPoly(ɛ‐caprolactone) (PCL) is explored in tissue engineering (TE) applications due to its biocompatibility, processability, and appropriate mechanical properties. However, its hydrophobic nature and lack of functional groups in its structure are major drawbacks of PCL‐based scaffolds limiting appropriate cell adhesion and proliferation. In this study, silk fibroin (SF) was immobilized on the surface of electrospun PCL nanofibers via covalent bonds in order to improve their hydrophilicity. To this end, the surface of PCL nanofibers was activated by ultraviolet (UV)–ozone irradiation followed by carboxylic functional groups immobilization on their surface by their immersion in acrylic acid under UV radiation and final immersion in SF solution. Furthermore, morphological, mechanical, contact angle, and Attenuated total reflection‐ Fourier transform infrared (ATR‐FTIR) were measured to assess the properties of the surface‐modified PCL nanofibers grafted with SF. ATR‐FTIR results confirmed the presence of SF on the surface of PCL nanofibers. Moreover, contact angle measurements of the PCL nanofibers grafted with SF showed the contact angle of zero indicating high hydrophilicity of modified nanofibers. In vitro cell culture studies using NIH 3T3 mouse fibroblasts confirmed enhanced cytocompatibility, cell adhesion, and proliferation of the SF‐treated PCL nanofibers. © 2018 Wiley Periodicals, Inc.

Electrochemical, Spectroelectrochemical, Mößbauer, and EPR Spectroscopic Studies on Ferrocenyl‐Substituted Tritylium Dyes

Published: June 2018

AbstractFour monoferrocenyl tritylium derivatives with donor‐substituted (OMe, NMe2) aryl rings are reported, along with their spectroscopic and electrochemical properties. All the complexes show a one‐electron reduction and a quasi‐reversible ferrocene oxidation at a very positive potential. Small quadrupole splittings, ΔEQ, in Mößbauer spectra agree with highly electron‐deficient ferrocenes. Comparison of the experimental half‐wave potentials for ferrocene oxidation,E1/2(Fc/Fc+), with those estimated from established correlations ofE1/2(Fc/Fc+) with ΔEQindicates that theE1/2values of the anisyl‐substituted congenersFcOMe+andFcMeOMe+are affected by Coulombic repulsion between the positive charges at the Fe ion and the neighboring methylium site. Electronic spectra are recorded and interpreted with the aid of quantum chemical calculations. UV/Vis spectroelectrochemical measurements as well as chemical reduction provide insight into the redox‐induced color changes upon ferrocene oxidation or upon reduction to the neutral trityl radicals. The neutral radicals reversibly form EPR‐silent dimers. This process is studied by temperature‐dependent EPR spectroscopy, and thermodynamic data for their dimerization are determined. Experimental and quantum chemical data suggest that the dimers assume classical hexaarylethane structures as opposed to normal or “offset” Jacobson–Nauta‐type structures.
