A Text Analytics-Based Importance Performance Analysis and Its Application to Airline Service
Authors: Nam Seungju , Lee Hyun Cheol
Published: November 2019

We introduce a new importance-performance analysis (IPA) methodology while making use of direct service experience perceptions represented by online reviews with numerical ratings. The proposed IPA, which we call the text analytics-based IPA (TAIPA), allows the real-time calculation of importance using the probability distribution of word frequency via the latent Dirichlet allocation (LDA) application to online reviews, and of performance using numerical rating values. The importance is also adjusted with the help of a sentiment analysis of online reviews to provide more precise measurements for service experience perceptions. To ensure an evaluation of the entire service process, we employ service encounters, in which service experiences occur and thus most customer perceptions are created, as a set of attributes composed of LDA topics that contain direct perceptions of service experiences. We investigate statistical correlations between TAIPA calculations and typical benchmarks of firm performance in the air-transport industry to verify how effective the proposed TAIPA is with respect to the degree that customer satisfaction is represented. As a primary result, TAIPA is more effective than comparison targets in that it shows stronger correlations with firm performance. TAIPA is specialized in determining which service step (i.e., a one-to-one relationship with a service encounter) needs to be improved. Moreover, TAIPA is flexible in considering multiple competitors.

Published: November 2019

This study investigates the relationship between the quality of hospitality services and sustainable equestrian tourism development in Slovenia. The focus will be on the relations between equestrian tourism motivations, hospitality services quality, overall service quality, equestrian tourists’ satisfaction, and behavioral intentions. The target population was equestrian tourists who stayed in one of 30 tourism farms in Slovenia and used both accommodation and food and beverage services. Face-to-face surveys with convenience sampling were used for the data collection. The results show that equestrian tourism motivations are positively associated with both hospitality services quality and the overall service quality in equestrian tourism. Moreover, the overall service quality in equestrian tourism is positively related to equestrian tourists’ satisfaction, while equestrian tourists’ satisfaction is positively related to behavioral intentions. In addition, accommodation service quality and food and beverage service quality both mediate the association between equestrian tourism motivation and overall satisfaction. The study provides both theoretical and practical implications. For one thing, it fills the research gaps present in the literature. In addition, it gives practical guidelines to farmers and tourism practitioners regarding equestrian tourism development as one of the popular areas of sustainable tourism development in rural settings.
Delineation of Urban Growth Boundaries Using a Patch-Based Cellular Automata Model under Multiple Spatial and Socio-Economic Scenarios

Published: November 2019

The urban growth boundary (UGB) plays an important role in the regulation of urban sprawl and the conservation of natural ecosystems. The delineation of UGBs is a common strategy in urban planning, especially in metropolitan areas undergoing fast expansion. However, reliable tools for the delineation of informed UGBs are still not widely available for planners. In this study, a patch-based cellular automaton (CA) model was applied to build UGBs, in which urban expansions were represented as organic and spontaneous patch growing processes. The proposed CA model enables the modeler to build various spatial and socio-economic scenarios for UGB delineation. Parameters that control the patch size and shape, along with the spatial compactness of an urban growth pattern, were optimized using a genetic algorithm. A random forest model was employed to estimate the probability of urban development. Six scenarios in terms of the demand and the spatial pattern of urban land allocation were constructed to generate UGB alternatives based on the simulated urban land maps from the CA model. Application of the proposed model in Ezhou, China from 2004 to 2030 reveals that the model proposed in this study can help urban planners make informed decisions on the delineation of UGBs under different scenarios.
Identifying Consumer Lifestyles through Their Energy Impacts: Transforming Social Science Data into Policy-Relevant Group-Level Knowledge
Authors: Schwarzinger Stephan , Bird David Neil , Skjølsvold Tomas Moe
Published: November 2019

The analytical framework presented herein is based on the identification of social groups with distinct patterns in their energy-relevant behaviour. This was achieved by clustering individuals according to their primary energy demands in six main areas of life. Due to the close relationship between energy-relevant behaviour and associated impacts, the suggested approach is considered better suited for the identification of groups with actual differences in their climate and energy-related behaviour than conventional approaches that cluster individuals based on their psychological or sociodemographic characteristics. Moreover, it is assumed that this focus on energy-relevant behaviour leads to a higher measuring equivalence in a country comparison or in a longitudinal setting. From an analytical point of view, the most significant benefit of the presented method over conventional lifestyle typologies is that all psychological, cultural and sociodemographic factors can be used as explanatory variables without resulting in circular reasoning. In terms of required data, the approach was designed around what could be collected by conventional survey methods. Variables such as energy use and emissions were calculated by the means of life cycle assessment (LCA) based on self-reported behaviour and equipment use.

The Symmetry of Pairing and the Electromagnetic Properties of a Superconductor with a Four-Fermion Attraction at Zero Temperature
Authors: Tarasewicz Przemyslaw
Published: November 2019

Properties of a fermion system at zero temperature are investigated. The physical system is described by a Hamiltonian containing the BCS interaction and an attractive four-fermion interaction. The four-fermion potential is caused by attractions between Cooper pairs mediated by the phonon field. In this paper, the BCS interaction is assumed to be negligible and the four-fermion potential is the only one that acts in the system. The effect of the pairing symmetry used in the four-fermion potential on some zero-temperature properties is studied. This especially concerns the electromagnetic response of the system to an external magnetic field. It turns out that, in this instance, there are serious differences between the conventional BCS system and the one investigated in this paper.
Numerical Study of Natural Convection Flow of Nanofluid Past a Circular Cone with Cattaneo–Christov Heat and Mass Flux Models
Authors: Iqbal Muhammad Saleem , Khan Waqar , Mustafa Irfan , Ghaffari Abuzar
Published: November 2019

The objective of this study is to analyze the natural convection flow of nanofluid along a circular cone placed in a vertical direction. The generalized heat flux and mass flux models are commonly known as the Cattaneo–Christov heat flux model and mass flux models. In the present study, these models are used for both heat and mass transfers analysis in nanofluid flow. For the governing equations, the Buongiorno transport model is used in which two important slip mechanism, namely thermophoresis and Brownian motion parameters, are discussed. The resulting governing equations in the form of partial differential equations (PDEs) are converted into ordinary differential equations (ODEs) due to similar flow along the surface of a circular cone. To solve these ODEs, a numerical algorithm based on implicit finite difference scheme is utilized. The effects of dimensionless parameters on heat and mass transfer in nanofluid flow are discussed graphically in the form of velocity profile, temperature profile, Sherwood number and Nusselt number. It is noted that in the presence of the Cattaneo–Christov heat flux model and mass flux model, the heat transfer rate decreases by increasing both thermal and concentration relaxation parameters; however, Sherwood number decreases by increasing the thermal relaxation parameter, and increases by increasing the concentration relaxation parameter.

Authors: Matychyn Ivan
Published: November 2019

This paper deals with the initial value problem for linear systems of fractional differential equations (FDEs) with variable coefficients involving Riemann–Liouville and Caputo derivatives. Some basic properties of fractional derivatives and antiderivatives, including their non-symmetry w.r.t. each other, are discussed. The technique of the generalized Peano–Baker series is used to obtain the state-transition matrix. Explicit solutions are derived both in the homogeneous and inhomogeneous case. The theoretical results are supported by examples.
Simultaneous Immunization with Multivalent Norovirus VLPs Induces Better Protective Immune Responses to Norovirus than Sequential Immunization
Authors: Malm Maria , Vesikari Timo , Blazevic Vesna
Published: November 2019

Human noroviruses (NoVs) are a genetically diverse, constantly evolving group of viruses. Here, we studied the effect of NoV pre-existing immunity on the success of NoV vaccinations with genetically close and distant genotypes. A sequential immunization as an alternative approach to multivalent NoV virus-like particles (VLPs) vaccine was investigated. Mice were immunized with NoV GI.3, GII.4-1999, GII.17, and GII.4 Sydney as monovalent VLPs or as a single tetravalent mixture combined with rotavirus VP6-protein. Sequentially immunized mice were primed with a trivalent vaccine candidate (GI.3 + GII.4-1999 + VP6) and boosted, first with GII.17 and then with GII.4 Sydney VLPs. NoV serum antibodies were analyzed. Similar NoV genotype-specific immune responses were induced with the monovalent and multivalent mixture immunizations, and no immunological interference was observed. Multivalent immunization with simultaneous mix was found to be superior to sequential immunization, as sequential boost induced strong blocking antibody response against the distant genotype (GII.17), but not against GII.4 Sydney, closely related to GII.4-1999, contained in the priming vaccine. Genetically close antigens may interfere with the immune response generation and thereby immune responses may be differently formed depending on the degree of NoV VLP genotype identity.

Published: November 2019

Zika virus (ZIKV) infection during pregnancy leads to severe congenital Zika syndrome, which includes microcephaly and other neurological malformations. No therapeutic agents have, so far, been approved for the treatment of ZIKV infection in humans; as such, there is a need for a continuous effort to develop effective and safe antiviral drugs to treat ZIKV-caused diseases. After screening a natural product library, we have herein identified four natural products with anti-ZIKV activity in Vero E6 cells, including gossypol, curcumin, digitonin, and conessine. Except for curcumin, the other three natural products have not been reported before to have anti-ZIKV activity. Among them, gossypol exhibited the strongest inhibitory activity against almost all 10 ZIKV strains tested, including six recent epidemic human strains. The mechanistic study indicated that gossypol could neutralize ZIKV infection by targeting the envelope protein domain III (EDIII) of ZIKV. In contrast, the other natural products inhibited ZIKV infection by targeting the host cell or cell-associated entry and replication stages of ZIKV. A combination of gossypol with any of the three natural products identified in this study, as well as with bortezomib, a previously reported anti-ZIKV compound, exhibited significant combinatorial inhibitory effects against three ZIKV human strains tested. Importantly, gossypol also demonstrated marked potency against all four serotypes of dengue virus (DENV) human strains in vitro. Taken together, this study indicates the potential for further development of these natural products, particularly gossypol, as the lead compound or broad-spectrum inhibitors against ZIKV and other flaviviruses, such as DENV.
Emerging Role of LY6E in Virus–Host Interactions
Authors: Yu Jingyou , Liu Shan-Lu
Published: November 2019

As a canonical lymphocyte antigen-6/urokinase-type plasminogen activator receptor Ly6/uPAR family protein, lymphocyte antigen 6 complex, locus E (LY6E), plays important roles in immunological regulation, T cell physiology, and oncogenesis. Emerging evidence indicates that LY6E is also involved in the modulation of viral infection. Consequently, viral infection and associated pathogenesis have been associated with altered LY6E gene expression. The interaction between viruses and the host immune system has offered insights into the biology of LY6E. In this review, we summarize the current knowledge of LY6E in the context of viral infection, particularly viral entry.

Published: November 2019

Multisystemic inflammation in pigs affected by porcine circovirus type 2 (PCV2) indicates the disordered expression of inflammatory cytokines. However, the PCV2-induced expression profile of inflammation cytokines and its regulating mechanism remain poorly understood. In this study, inflammatory cytokines and receptors in porcine alveolar macrophages (PAMs) after PCV2 infection were profiled in vitro by an RT2 ProfilerTM PCR array assay. The regulatory mechanism of interleukin-1β (IL-1β) expression was investigated. Results showed that 49 of 84 inflammation cytokines and receptors were differentially expressed (p < 0.05, absolute fold change ≥2) in PAMs at different stages post-PCV2 infection. Moreover, the overexpression of single-immunoglobulin interleukin-1 related receptor (SIGIRR) or the blocking of NF-κB activation by its inhibitor markedly decreased IL-1β secretion. This finding suggested that PCV2-induced overexpression of IL-1β was associated with the downregulation of SIGIRR and the activation of NF-κB. Furthermore, the excessive activity of NF-κB in SIGIRR-knockout PAMs cell line, indicating that SIGIRR negatively regulated IL-1β production by inhibiting the activation of NF-κB. Overall, PCV2-induced downregulation of SIGIRR induction of NF-κB activation is a critical process in enhancing IL-1β production in PAMs. This study may provide insights into the underlying inflammatory response that occurs in pigs following PCV2 infection.

Published: November 2019

Antarctic cryoconite holes, or small melt-holes in the surfaces of glaciers, create habitable oases for isolated microbial communities with tightly linked microbial population structures. Viruses may influence the dynamics of polar microbial communities, but the viromes of the Antarctic cryoconite holes have yet to be characterized. We characterize single-stranded DNA (ssDNA) viruses from three cryoconite holes in the Taylor Valley, Antarctica, using metagenomics. Half of the assembled metagenomes cluster with those in the viral family Microviridae (n = 7), and the rest with unclassified circular replication associated protein (Rep)-encoding single-stranded (CRESS) DNA viruses (n = 7). An additional 18 virus-like circular molecules encoding either a Rep, a capsid protein gene, or other unidentified but viral-like open reading frames were identified. The samples from which the genomes were identified show a strong gradient in microbial diversity and abundances, and the number of viral genomes detected in each sample mirror that gradient. Additionally, one of the CRESS genomes assembled here shares ~90% genome-wide pairwise identity with a virus identified from a freshwater pond on the McMurdo Ice Shelf (Antarctica). Otherwise, the similarity of these viruses to those previously identified is relatively low. Together, these patterns are consistent with the presence of a unique regional virome present in fresh water host populations of the McMurdo Dry Valley region.

Published: November 2019

Recent studies have shown that transcriptomic analysis of blood samples taken from patients with acute Ebola virus disease (EVD) during the 2013–2016 West African outbreak was suggestive that a severe inflammatory response took place in acutely ill patients. The significant knowledge gained from studying the Makona variant, a cause of the largest known EVD outbreak, may be applicable to other species of ebolavirus, and other variants of the Ebola virus (EBOV) species. To investigate the ability of Makona to initiate an inflammatory response in human macrophages and characterise the host response in a similar manner to previously characterised EBOV variants, the human monocytic cell line THP-1 was differentiated into macrophage-like cells and infected with Makona. RNA-Seq and quantitative proteomics were used to identify and quantify host mRNA and protein abundance during infection. Data from infection with Reston virus (RESTV) were used as comparators to investigate changes that may be specific to, or enhanced in, Makona infection in relation to a less pathogenic species of ebolavirus.. This study found demonstrable induction of the inflammatory response, and increase in the activation state of THP-1 macrophages infected with Makona. NFκB and inflammation-associated transcripts displayed significant changes in abundance, reflective of what was observed in human patients during the 2013–2016 EBOV outbreak in West Africa, and demonstrated that transcriptomic changes found in Makona-infected cells were similar to that observed in Reston virus infection and that have been described in previous studies of other variants of EBOV.

Published: November 2019

Succinate Coenzyme A ligase beta-like protein (SUCLA-β) is a subunit of Succinyl-coenzyme A synthetase, which is involved in substrate synergism, unusual kinetic reaction in which the presence of SUCLA-β for one partial reaction stimulates another partial reaction. Trichinella spiralis is a parasitic nematode, which may hinder the development of autoimmune diseases. Immunomodulatory effects of SUCLA-β from Trichinella spiralis in the parasite-host interaction are unidentified. In this study the gene encoding T. spiralis SUCLA-β was cloned and expressed. Binding activities of recombinant T. spiralis SUCLA-β (rTs-SUCLA-β) to rat peripheral blood mononuclear cells (PBMCs) were checked by immunofluorescence assay (IFA) and the immuno-regulatory effects of rTs-SUCLA-β on cell migration, cell proliferation, nitric oxide (NO) production and apoptosis were observed by co-incubation of rTs-SUCLA-β with rat PBMCs in vitro, while cytokine secretions in rTs-SUCLA-β treated rats were evaluated in vivo. Furthermore, phagocytosis of monocytes was detected by flow cytometry and effects of rTs-SUCLA-β-induced protective immunity on T. spiralis adult worms and muscle larva were evaluated in rats. The IFA results revealed that rTs-SUCLA-β could bind to rat PBMCs. Treatment of PBMCs with rTs-SUCLA-β significantly decreased the monocyte phagocytosis, cell migration and cell proliferation, while NO production and apoptosis of PBMCs were unaffected. Results of the in vivo study showed that the IL-17 secretion decreased significantly after rTs-SUCLA-β administration in rats, while no significant effects were observed on the secretions of IFN-γ, IL-9, TGF-β and IL-4. Moreover, significant reduction of T. spiralis muscle larvae burden and significant increase in anti-rTs-SUCLA-β immunoglobulin level of IgG, IgG1 and IgG2a was observed in rTs-SUCLA-β-administered rats. The results indicated that rTs-SUCLA-β may be a potential target for controlling T. spiralis infection by suppressing the immune functions of the rat PBMCs and by reducing the parasite burden. Additionally it may also contribute to the treatment of autoimmune diseases and graft rejection by suppressing IL-17 immune response in the host.
The Use of Digital Terrain Models to Estimate the Pace of Filling the Pit of a Central European Granite Quarry with Water

Published: November 2019

This paper presents the results of an analysis of the pace of filling one of the deepest European granite quarries with water. A DTM (digital terrain model) based on data from LiDAR ALS (light detection and ranging airborne laser scanning) was used to create a model of the pit of the Strzelin I granite quarry and to determine the reach and surface area of the direct catchment of the excavation pit. The increase in the volume of water in the excavation pit was determined. Analogue maps and DTM were used to calculate the maximum depth of the pit (113.3 m), its surface area (9.71 ha), and its capacity (5.1 million m3). The volume of water collected in the excavation pit during the years 2011–2018 was determined based on the analogue base map and the DTM. The result was 0.335 million m3. Based on the data made available by the mining company, the correlation of the DTM with the orthophotomap of the mining area and additional field measurements, the ordinates of the water level in the years 2011–2018 were determined. Initially, the water surface level in the quarry was located on the ordinate of 66.6 m a.s.l. (July 20, 2011). After the pumping of water was discontinued, the level rose to 96.1 m a.s.l. (January 28, 2018). The increase in the water volume in the quarry pit during specific periods was determined (actual retention increase). The obtained data on the volume of the retained water referred to the period during which it accumulated in the quarry. On average, the net increase in water retention in the excavation pit was 138.537 m3∙d−1, and the calculated net supply from the direct catchment (16.04 ha) was 101.758 m3∙d−1. The use of DTM and measurements of the water level in the excavation pit seem to be an efficient means of estimating the pace of spontaneous filling of the quarry with water supplied from the direct physiographic catchment.

Published: November 2019

Mn(III) oxidation technology has attracted increasing interest in recent years because of its fast decontamination kinetics and second-pollution-free characteristic. Whether it can be used as a pre-oxidation step to enhance conventional coagulation process remains to be evaluated. Herein, an Fe-coagulation/sedimentation process combined with Mn(III) pre-oxidation (Mn(III)+C/S), hypochlorite pre-oxidation (Cl2+C/S), and permanganate pre-oxidation (PM+C/S) was applied to treat simulated micro-polluted raw water. The removal performance of routine water quality indices (turbidity, dissolved organic carbon, total nitrogen, nitrate-nitrogen, ammonia-nitrogen, Pb(II), and Cr(VI)) and the emerging pollutants (acesulfame, carbamazepine, bisphenol S, and nano-ZnO) created by these three processes were researched. The mechanism of how Mn(III) pre-oxidation influences C/S was explored by identifying the transformation products of Mn(III), measuring the timely variation of flocs’ zeta potential and size, and scanning flocs’ micromorphology. Compared to Cl2+C/S and PM+C/S, Mn(III)+C/S exhibited its superiority in removing dissolved organic carbon (72.9%), total nitrogen (31.74%), and emerging pollutants (21.78%–93.49%). The enhanced removal of these contaminants by Mn(III)+C/S found its explanation in the strong oxidation power of Mn(III) and the multiple roles of in-situ formed MnO2 (e.g., flocculation core, adsorption co-precipitant, and densification agent). The acute toxicity tests confirmed that water treated by Mn(III)+C/S did not show a significant change in the associated toxicity. The findings of the present study indicate that Mn(III) oxidation technology shows great potential as an alternative to pre-oxidation technology of waterworks.
Reconstruction of Seasonal Net Erosion in a Mediterranean Landscape (Alento River Basin, Southern Italy) over the Past Five Decades
Authors: Diodato Nazzareno , Bellocchi Gianni
Published: November 2019

In the low Mediterranean basin, late spring and autumn rainfall events have the potential to increase discharge and transport substantial amounts of sediment soil (that is, the net soil erosion from a watershed). For the Alento River Basin (ARB), located in the low Tyrrhenian coast of Italy, we estimated changes of net erosion as dependent on the seasonality of antecedent soil moisture and its control on rainfall-runoff and erosivity. Based on rainfall and runoff erosivity sub-models, we developed a simplified model to evaluate basin-wide sediment yields on a monthly basis by upscaling point rainfall input. For the period 1951–2018, the reconstruction of a time series of monthly net erosion data indicated a decreasing trend of the sediment yield after 1991. Revegetation and land abandonment that occurred in the last decades can explain such a decrease of net erosion, which occurred even when rainfall erosivity increased. This response, obtained at the basic scale, does not exclude that rapidly developing mesoscale convective systems, typically responsible for the heaviest and most destructive rainfall events in the ARB, can affect small catchments, which are the most vulnerable systems to storm-driven flash floods and soil erosion hazards during soil tilling in spring and at beginning of autumn.

Published: November 2019

Indicator systems can improve water governance by integrating and simplifying data on water resources. However, to our knowledge, no indicator systems have been comprehensively assessed against the water governance framework within which they operate. We assess the policy relevance of the Freshwater Health Index (FHI) to the governance frameworks of Lao PDR, Cambodia, and Viet Nam. These governance frameworks were chosen because the FHI has been applied to the transboundary Sesan, Srepok, and Sekong (3S) river basin, which traverses the three nations. We conduct an institutional analysis, assessing the FHI indicators against each nation’s relevant laws, plans, policies and strategies, as well as international agreements. The FHI indicators varied in their alignment with the 3S’s transboundary water governance framework. Ecosystem Vitality indicators, which measure environmental health, tended to show a greater alignment than Ecosystem Service indicators. The Governance and Stakeholders indicators, which assess aspects of the governance system, were highly relevant. Comparing the 3S FHI assessment results to the water governance framework provided a case for delivering environmental flows and headwater reforestation, and improving biodiversity protection and fish passage. The generally close alignment of FHI metrics with the 3S’s water governance frameworks shows that the FHI is a policy-relevant tool.

Remarques sur les conditions d'application de la loi d'action de masse à la détermination des paramètres thermodynamiques des minéraux à basse température
Authors: Dandurand Jean-Louis , Schott Jacques
Published: November 2019

La loi d'action de masse, appliquée aux systèmes aqueux supposés à l'équilibre, est un moyen précieux pour la description des systèmes naturels et l'établissement des relations de stabilité entre les espèces.

Il semble, cependant, qu'elle ait été parfois abusivement utilisée, sans respect de ses conditions strictes d'application, notamment dans le domaine des basses températures.

Mis à part les impératifs de pureté chimique et d'homogénéité des composés étudiés, l'application de la loi d'action de masse suppose que deux conditions fondamentales soient réalisées :

1° elle est strictement subordonnée au fait que la réaction considérée soit dans un état d'équilibre vrai ;

2° la constante d'équilibre ainsi calculée et les paramètres thermodynamiques qui peuvent en être déduits ne sont caractéristiques du composé que si l'équilibre est obtenu avec un monocristal de taille infinie.

Ces conditions sont discutées et tout particulièrement la notion d'équilibre vrai. L'examen des critères théoriques et pratiques permettant de différencier les états stationnaires des états d'équilibre fait apparaître que la réversibilité est l'unique critère pratique permettant de mettre en évidence les états d'équilibre stable ou métastable, auxquels seuls sont applicables la loi d'action de masse.

Expérimentalement, la détermination des activités des espèces en solution en vue de l'application de la loi d'action de masse peut être réalisée soit à l'équilibre — obtenu à la fois « par le haut » (cristallisation) et « par le bas » (dissolution) — soit par extrapolation des cinétiques initiales de dissolution du minéral. Ce dernier procédé est d'emploi délicat dans la mesure où la valeur obtenue par extrapolation est sensible à la cinétique de dissolution du minéral. En outre, il ne présente un intérêt qu'appliqué à des composés dont l'équilibre vrai, par dissolution, est impossible à atteindre dans les conditions opératoires utilisées, notamment dans le cas de composés non synthétisables dans ces conditions ; or, dans ce cas, la légitimité de son emploi est sujette à caution.

Enfin, sont examinées les conditions d'application de la loi d'action de masse aux solutions solides. On montre que les deux formulations « produits de solubilité partiels » et « produit de solubilité total », sont équivalentes lorsque l'équilibre est supposé être réalisé. Cependant, la seule formulation du « produit de solubilité total » est insuffisante pour décrire l'équilibre.

Pratiquement, pour déterminer les paramètres thermodynamiques d'une solution solide homogène par des essais de dissolution, il faut que celle ci soit congruente : les essais par dissolution doivent être réalisés dans des conditions telles que, lorsque l'équilibre est atteint, la solution solide étudiée serait synthétisable. Ils ne peuvent donc être entrepris que lorsqu'on connaît les conditions de synthèse de cette solution solide particulière.
Solubilité et grandeurs thermodynamiques de dissolution des zéolites 4A et 13X dans des solutions aqueuses basiques
Authors: Caullet Philippe , Guth Jean-Louis , Wey Raymond
Published: November 2019

Dans le domaine de pH (soude 0,02, 0,10 et 0,50 M) et de température (25, 60 et 80 °C) étudié, les zéolites 4 A et 13 X conservent pendant au moins deux mois une parfaite stabilité structurale. L'analyse des échantillons par spectroscopie de photoélectrons induits par rayons X (XPS) montre par ailleurs que la solubilisation est stœchiométrique. Un pseudo-équilibre de solubilité est plus ou moins rapidement atteint. Mais, par suite de l'existence de phénomènes parasites, les valeurs de solubilité mesurées sont faussées lorsque le pourcentage de zéolite dissoute est faible. Ces erreurs deviennent négligeables à condition d'effectuer la mesure avec un rapport liquide/solide suffisamment grand (500). On observe que la solubilité croît avec la température et le pH ; elle est toujours légèrement plus importante pour la zéolite 4 A. Les résultats obtenus permettent, moyennant quelques hypothèses concernant les ions en solution, de calculer les grandeurs thermodynamiques correspondant à l'équilibre de dissolution suivant :

NaAl Si[x] O[2(x + 1)] + 2(x + 1)H₂O ⇋ Al(OH)₄⁻ + xSi(OH)₄ + Na⁺

Organisation des molécules d'eau dans les silicates de grande surface spécifique
Authors: Fripiat José Jean
Published: November 2019

Les propriétés dynamiques de la molécule d'eau dans un amas tridimensionnel au sein de la supercage d'un tamis 13 X et d'un film bidimensionnel dans l'espace interlamellaire de phyllosilicates sont très différentes. Dans l'amas globulaire, la dynamique est similaire à celle de la molécule d'eau en phase liquide, tandis que dans l'espace interlamellaire deux mouvements de rotation sont couplés.

Ces différences se reflètent dans la variation de la chaleur spécifique de l'eau en fonction de la température et les caractéristiques des spectres RMN des ions échangeables.
Nacrt ekološke duhovnosti prema enciklici Laudato sì pape Franje
Authors: Parlov Mladen
Published: November 2019

In the wake of the Pope Francis' encyclical Laudato sì which talks about the Earth as a common home of all people, the author offers a draft of ecological spirituality. The beginning of true eco-spirituality is ecological conversion, which is nothing else but a renewed consciousness that from our faith and encounter with Jesus Christ we also ought to change our relationship with the world around us. Ecological conversion should help the faithful to repeatedly and correctly develop their awareness of having been created, of their own immersion into the world of creatures with which they are interconnected. Correct ecological attitude leads to internal balance of the man himself, to solidarity with others, to natural balance of all living beings and to spiritual balance with God. Ecological awareness can help not only to preserve the environment, which is one of the basic goals, but also to change the way of behaviour, which can raise the quality of life of both the individual and the family. Ecological spirituality understands and lives the sacraments in a new way, as a means of salvation and sanctification, because in the sacraments God uses the visible matter in order to communicate his (invisible) grace. Eco-spirituality calls for upbringing and adopting new attitudes in the lives of contemporary Christians which need to help them to properly treat the created world.
Svjetske konferencije ekumenskog vijeća crkava i odnos prema stvorenome (1948. - 2013.)
Authors: Macut Ivan
Published: November 2019

Rad uz uvod i nekoliko zaključnih misli ima dva poglavlja. U prvom poglavlju pod naslovom Ukratko o nastanku i radu Ekumenskog vijeća crkava u nekoliko poteza donosimo nastanak ovog važnog Vijeća na globalnoj razini te donosimo i popis svih deset svjetskih konferencija koje su održavane od 1948. do 2013. godine. Drugo poglavlje rada ima naslov Tematika odnosa prema stvorenome na svjetskim konferencijama Ekumenskog vijeća crkava. U njemu se govori o glavnim ekološkim temama, naglascima, poticajima i upozorenjima na pojedinim svjetskim konferencijama Ekumenskog vijeća crkava. Svjetska ekumenska asembleja u Seulu 1990. godine dala je odlučujući poticaj za bavljenje ekološkom tematikom, a prvi put Ekumensko vijeće crkava izravno o stvorenom svijetu i ekologiji govori na Sedmoj svjetskoj skupštini u Canberri 1991. godine. Naravno, i Osma svjetska skupština u Harareu 1998. godine, Deveta u Porto Alegreu 2006. te, naposljetku, Deseta svjetska skupština u Busanu 2013. godine bave se u jednom dijelu više ili manje istom tematikom. Pri kraju rada donijeli smo i Izjavu o klimatskoj pravdi Izvršnog odbora Ekumenskog vijeća crkava iz 2016. godine.
Odgoj za katoličku ekopedagogiju s posebnim naglaskom na vjerski odgoj srednjoškolaca u obrazovnom sustavu Republike Hrvatske
Authors: Prović Mihael
Published: November 2019

Konstantnim razvojem suvremenoga društva čovjek se sve više brine oko napretka i usavršavanja raznih tehničkih, tehnoloških i drugih disciplina, pritom ne mareći što iscrpljuje prirodne resurse, uništava prirodu i zagađuje okoliš. Katolička Crkva svojom ekopedagogijom već desetljećima, na razne načine, pokušava razvijati ekološku svijest svih svojih vjernika, posebno srednjoškolaca, kako bismo vjerskim odgojem i obrazovanjem postali svjesni opasnosti koja bi nas jednog dana mogla zadesiti zbog neodgovornog ponašanja prema prirodi, koja je osnovno i jedino stanište ljudskog roda. Autor u radu prikazuje mogućnosti ekološkog osvješćivanja srednjoškolaca preko teološkoga i pedagoškog vida vjeronaučne nastave. Referirajući se na društveno-humanistički pristup odgoja i obrazovanja, prema dokumentu Nacionalni okvirni kurikulum za predškolski odgoj i obrazovanje te opće obvezno i srednjoškolsko obrazovanje, autor proučava sadržaj katoličkog vjerskog odgoja u dokumentu Plan i program katoličkog vjeronauka za četverogodišnje srednje škole, te razmatra mogućnosti i utjecaj vjeronaučne nastave pri razvijanju senzibilnosti srednjoškolaca za ekološke teme i odgovoran odnos prema očuvanju prirode, njezinih resursa i čistoće okoliša. Autor predlaže nove pedagoške principe u tumačenju uloge katoličke ekopedagogije i izbora njezinih sadržaja, ciljeva i metoda odgoja u vjeronaučnoj nastavi.

Oil extraction from Cashew nut was carried out by Soxhlet method using n-hexane as the solvent. The oil was transesterified to produce Fatty Acid Methyl-Esters (FAMEs) and glycerol. Fenugreek and Moringa seed oils were purchased from the market. GC- Analysis gave the following fatty acids composition: Oleic (74.99%), Linoleic (1.27%), Stearic (2.09%), Myristic (0.86%), Lauric (1.97%), Linolenic (1.75%), Palmitic (12.51%) and Palmitoleic (2.70%) for Moringa oil; Oleic (67.62%), Linoleic (16.99%), Stearic (8.42%) and Palmitic (6.93%) for Cashew oil while Fenugreek oil constituted of Oleic (20%), Linoleic (42.5%), Stearic (6.5%), Linolenic (18%), Palmitic (10.5%) and Arachidonic (0.5%). The study revealed that the three vegetable seeds are good sources of edible oils. Cashew oil is considered to be the most suitable for food formulation as well as pharmaceutical, paint, soap and perfume industries because of high level of unsaturated in the fatty acid contents.
