title: Leachate treatment by combined processes: coagulation/flocculation, air stripping, ozonation and activated sludge

description: ABSTRACT Leachate from waste disposal areas generally presents high complexity, variability, toxicity, recalcitrance and high concentration of ammonia nitrogen. In this work, combined techniques for the treatment of leachate were applied, namely: coagulation/flocculation, air stripping and ozonation combined with activated sludge treatment with/without activated carbon. The coagulation/flocculation process led to a COD reduction of 58.1% and color removal of 85.6%. The air stripping was performed at pH&gt;12 and reduced ammonia levels below of 60 mg.L-1. The ozonation process (ozone consumption of 397 mgO3.L-1 and 2376 mgO3.L-1) presented good results. It was observed a BOD5/COD increase of 59.4% and a toxicity reduction of more than 85%. The best efficiency was observed with sludge activated without activated carbon for the pre-treated leachate by coagulation/flocculation + air stripping + ozonation (400 mgO3.L-1). This combination resulted in a COD reduction of 90.6% and more than 99% of ammonia nitrogen removal.

title: Thermodynamic properties of water desorption in Buchenavia capitata (Vahl) Eichler

description: ABSTRACT Thermodynamic properties provide information on energy demand and kinetic parameters in water sorption processes in agricultural products. Such information is essential to analyze and scale drying and storage equipment. The objective of this study was to determine the thermodynamic properties involved in the water desorption process in Buchenavia capitata (Vahl) Eichler seeds with moisture contents ranging from 13.31 to 7.21% dry basis (d.b.), obtained by the indirect static method, at temperatures of 10, 20, 30 and 40 °C. The latent heat of vaporization, differential entropy and Gibbs free energy increase with the reduction of the moisture content of the seeds. The enthalpy-entropy compensation theory is valid for the desorption process, which is controlled by the enthalpy. The desorption of water in the seeds is not a spontaneous process.

title: Study of the drying of mesocarp of baru (Dipteryx alata Vogel) fruits

description: ABSTRACT Baru (Dipteryx alata Vogel) is a tree species that is part of the group of native species of the Cerrado and occurs mainly in Central Brazil, being valued for its various uses. Thus, the present work was carried out with the objective of studying the kinetics of drying of the mesocarp of baru fruits, performing the analysis of the thermodynamic properties, as well as evaluating the effect of drying on the color of the flour produced from the mesocarp. The mesocarp of baru fruits was placed in stainless steel trays, and dried at 40, 50, 60 and 70 ºC in a forced circulation oven until the moisture content of 0.12 dry basis (d.b.) was reached. Subsequently, the experimental data of the drying were adjusted with the mathematical models frequently used, and color was evaluated after the drying. It is concluded that the Wang & Singh model was selected to represent the drying curves of the baru mesocarp. For the thermodynamic properties, with increasing drying air temperature, the entropy and enthalpy values decreased while the Gibbs free energy increased. Regarding color, the results showed that with the increase of drying air temperature, there is a change in color, which indicates loss in the qualitative aspect.

title: Dentoalveolar Evaluation of Lower Incisors by CBCT after Treatment with Herbst Appliance

description: Abstract This study aimed to evaluate the effects of the Herbst appliance on the proclination and protrusion of the lower incisors, and to verify if the device causes alveolar bone loss in the anterior region of the mandible. This is a retrospective study. The sample consisted of 35 individuals. The treatment group consisted of 22 individuals (8 girls and 14 boys; initial mean age of 8.2 years) who used the Cantilever Herbst appliance for a period of 12 months. The control group consisted of 13 individuals (3 girls and 10 boys; initial mean age of 8.9 years) who received no treatment and were followed up for a period of approximately 18 months. Cone-beam computed tomography scans were performed at the beginning and at the end of the observational period. The medullary bone thickness (MT), buccal cortical bone thickness (BCT), lingual cortical bone thickness (LCT), and lower incisors proclination and protrusion were evaluated. Data were submitted to statistical analysis (ANCOVA and Student’s t-test) with a significance level of 5%. There was no significant difference in MT, BCT, LCT and incisor proclination between groups. Incisor proclination increased in the treated group with no statistical significance. The treatment group showed a significant increase in the protrusion of the incisors (p = 0.02). The Herbst appliance promoted a small proclination and protrusion of the lower incisors, without relevant clinical implications. The Herbst appliance did not cause bone loss in the anterior region of the mandible during Class II treatment.

title: Social capital and occupational assimilation of internal migrants in Peru

description: Abstract Internal migration is one of the phenomena that has shaped the Peruvian population, economy and geography in the last century. This study is based on the premise that migration is a complex process which may cause different effects on people depending on a variety of factors. This is particularly relevant if the aim is to evaluate the performance of migrants in a rigid market, such as the labor market. To that end, mechanisms are proposed, such as the contribution of civil society as well as other institutional arrangements, which can provide a range of benefits and services to members when markets are not perfect, as in the case of occupational elections. Therefore, the present work shows how social capital intervenes in the occupational assimilation of internal migrants in Peru. A simple theoretical model is presented in which it is stated that two types of social capital (ethnic and acquired) can offer different types of services to its members, depending on the level of complementarity of the same with the educational level and the duration of the migrant’s stay in their place of destination (recent and established migrants). Using the National Household Survey (2014) and a multinomial logit estimation, it is found that ethnic social capital increases the probability of performing an elementary occupation for recent migrants only, and that, for established migrants, the social capital acquired increases the probability of performing a highly qualified occupation.

title: Dataset for: Adaptation, chance, and history in experimental evolutionary reversals to unicellularity

description: Evolution is often deemed irreversible. The evolution of complex traits that require many mutations makes their reversal unlikely. Even in simpler traits, reversals might become less likely as neutral or beneficial mutations, with deleterious effects in the ancestral context, become fixed in the novel background. This is especially true in changes that involve large re-organizations of the organism and its interactions with the environment. The evolution of multicellularity involves the reorganization of previously autonomous cells into a more complex organism; despite the complexity of this change, single cells have repeatedly evolved from multicellular ancestors. These repeated reversals to unicellularity undermine the generality of Dollo’s law. In this paper we evaluated the dynamics of reversals to unicellularity from recently evolved multicellular phenotypes of the brewers' yeast Saccharomyces cerevisae. Even though multicellularity in this system evolved recently, it involves the evolution of new levels of selection. Strong selective pressures against multicellularity lead to rapid reversibility to single cells in all of our replicate lines, whereas counterselection favoring multicellularity led to minimal reductions to the rates of reversal. History and chance played an important role in the tempo and mode of reversibility, highlighting the interplay of deterministic and stochastic events in evolutionary reversals.

title: 50-Hz magnetic field impairs the expression of iron-related genes in the in vitro SOD1<sup>G93A</sup> model of amyotrophic lateral sclerosis

description: <b>Purpose:</b> We characterized the response to the extremely low frequency magnetic field (ELF-MF) in an in vitro model of familial Amyotrophic Lateral Sclerosis (<i>f</i>ALS), carrying two mutant variants of the superoxide dismutase 1 (SOD1) gene. <b>Materials and methods:</b> SH-SY5Y human neuroblastoma cells, stably over-expressing the wild type, the G93A or the H46R mutant SOD1 cDNA, were exposed to either the ELF-MF (50 Hz, 1 mT) or the sham control field, up to 72 h. Analysis of (i) viability, proliferation and apoptosis, (ii) reactive oxygen species generation, and (iii) assessment of the iron metabolism, were carried out in all clones in response to the MF exposure. <b>Results:</b> We report that 50-Hz MF exposure induces: (i) no change in proliferation and viability; (ii) no modulation of the intracellular superoxide and H<sub>2</sub>O<sub>2</sub> levels; (iii) a significant deregulation in the expression of iron-related genes <i>IRP1</i>, <i>MFRN1</i> and <i>TfR1</i>, this evidence being exclusive for the SOD1<sup>G93A</sup> clone and associated with a slight (<i>p</i> = .0512) difference in the total iron content. <b>Conclusions:</b> 50-Hz MF affects iron homeostasis in the in vitro SOD1<sup>G93A</sup> ALS model.

title: Nonlinear Indicator-Level Moderation in Latent Variable Models

description: Linear, nonlinear, and nonparametric moderated latent variable models have been developed to investigate possible interaction effects between a latent variable and an external continuous moderator on the observed indicators in the latent variable model. Most moderation models have focused on moderators that vary across persons but not across the indicators (e.g., moderators like age and socioeconomic status). However, in many applications, the values of the moderator may vary both across persons and across indicators (e.g., moderators like response times and confidence ratings). Indicator-level moderation models are available for categorical moderators and linear interaction effects. However, these approaches require respectively categorization of the continuous moderator and the assumption of linearity of the interaction effect. In this article, parametric nonlinear and nonparametric indicator-level moderation methods are developed. In a simulation study, we demonstrate the viability of these methods. In addition, the methods are applied to a real data set pertaining to arithmetic ability.

title: First record of Balkan <i>Thymus jankae</i> (Lamiaceae) from Ukraine, with taxonomic remarks on the species

description: The Balkan species <i>Thymus jankae</i> is documented for the first time from Ukraine on Mount Chorna Hora (Vynohradiv town, Transcarpathian region), which is ca. 300 km northwards from its main range. This species locality has long been overlooked due to misidentification of its early collections with other <i>Thymus</i> taxa. Despite its ambiguous taxonomy, available morphological, caryological, biogeographical, and molecular data support a species rank of <i>Th. jankae</i> and suggest its ancestral position within the <i>Thymus praecox</i>-group. Morphology and chromosome count (2<i>n</i> = 56) of plants from Ukraine are congruent with the data available for Balkan populations. Phytosociological survey of <i>Th. jankae</i> locus in Ukraine shows the species to be affiliated with the associations <i>Alysso alyssoidis-Sedetum</i> and <i>Festucetum pseudodalmaticae</i>, as well as a community physiognomically close to the association <i>Potentillo heptaphyllae-Festucetum rupicolae</i>. The first two associations are parts of biotopes (6110 and 6240) with priority status according to Annex I of the Habitats Directive (92/43/EEC) and represent respectively a pioneer community and subpannonic meadow steppe grassland with evident southern European relationships. Most likely, the discovered locality of <i>Th. jankae</i> is a relict northern outpost created by extinction of a part of the former species range, although its anthropogenic origin should not be also excluded. Conservation of <i>Th. jankae</i> in Ukraine on the national level is discussed.
