The Opera as a Fragment in the Literary Reception of Carl Maria von Weber’s Der Freischütz (Adam Mickiewicz, Heinrich Heine, Théophile Gautier)
Authors: Wojda Aleksandra
Published: August 2017

This article examines the influence of early 19th-century operatic culture on Romantic literature by focusing on the cultural, literary and transmedial (cross-genre) reception of one of the most popular works of the early Romantic opera, Der Freischütz by Carl Maria von Weber. More specifically, the analysis deals with that aspect of its influence which can be described as fragmentary reception. The article argues that examples of such fragmentary reception can be found in the works of Adam Mickiewicz, Heinrich Heine and Théophile Gautier. However, the central argument of this study is that the emergence of this type of trans-media links was, in a large measure, determined by a peculiar, fragmentary reception of operas. That model of reception had been popularized by a variety of trend-setting, opinion-making agents and institutions (the critics, the press), and enforced by mechanisms of socio-cultural and technological change (resulting in the broadening of the media landscape and the aesthetic sensibility of the general public). The article also claims that this reception model of the opera not only reinforced some structural elements of the operatic work itself but also prompted the writers to explore new ways of structuring their texts (a development encouraged by the upgrade of the fragment by the Romantic aesthetics). Thus early 19th-century socio-cultural and transmedial reception patterns of the opera can be seen as a spur to creativity and literary experimentation – a conclusion which casts doubt on the traditional view that it was a period when aesthetic idealism ruled supreme.

The International Committee of Medical Journal Editors (ICMJE) provides recommendations to improve the editorial standards and scientific quality of biomedical journals. These recommendations range from uniform technical requirements to more complex and elusive editorial issues including ethical aspects of the scientific process. Recently, registration of clinical trials, conflicts of interest disclosure, and new criteria for authorship, emphasizing the importance of responsibility and accountability, have been proposed. Last year, a new editorial initiative to foster sharing of clinical trial data was launched. This review discusses this novel initiative with the aim of increasing awareness among readers, investigators, authors and editors belonging to the Editors’ Network of the European Society of Cardiology.
Epistemic Disagreement and’Elu We’Elu
Authors: Halberstam Joshua
Published: August 2017

A lively exchange in recent epistemology considers the problem of epistemic disagreement between peers: disagreement between those who share evidence and have equal cognitive abilities. Two main views have emerged about how to proceed in such circumstances: be steadfast in maintaining one’s own view or conciliate, and suspend or reduce one’s confidence in one’s belief. Talmudic debates do seem to promote steadfastness, as the disputants are not called on to conciliate purely because they confront a disagreeing peer. But why? Third party judgments are even more problematic, for what epistemic warrant is there for choosing between a disagreement of superiors? A common explanation for Talmudic steadfastness is the notion’elu w’elu divrey ’Elohimkayim– both sides of Talmudic (or, more generally,halakhic) disputes have ‘heavenly’ legitimacy. But a closer look at this oft-quoted dictum and its various interpretations does not, in fact, reveal such support for steadfastness. Other explanations for Talmudic steadfastness are, therefore, required.
On the Babylonian Origin of Symbolic Logic
Authors: Schumann Andrew
Published: August 2017

The logical reasoning first appeared within the Babylonian legal tradition established by the Sumerians in the law codes which were first over the world: Ur-Nammu (ca. 2047 – 2030 B.C.); Lipit-Ishtar (ca. 1900 – 1850 B.C.), and later by their successors, the Akkadians: Hammurabi (1728 – 1686 B.C.). In these codes the casuistic law formulation began first to be used: “If/when (Akkadian: šumma) this or that occurs, this or that must be done” allowed the Akkadians to build up a theory of logical connectives: “... or…”, “… and…”, “if…, then…”, “not…” that must have been applied in their jurisprudence. So, a trial decision looked like an inference by modus pones and modus tollens or by other logical rules from (i) some facts and (ii) an appropriate article in the law code represented by an ever true implication. The law code was announced by erecting a stele with the code or by engraving the code on a stone wall. It was considered a set of axioms announced for all. Then the trial decisions are regarded as claims logically inferred from the law code on the stones. The only law code of the Greeks that was excavated is the Code of Gortyn (Crete, the 5th century B.C.). It is so similar to the Babylonian codes by its law formulations; therefore, we can suppose that the Greeks developed their codes under a direct influence of the Semitic legal tradition: the code was represented as the words of the stele and the court was a logic application from these words. In this way the Greek logic was established within a Babylonian legal tradition, as well. Hence, we can conclude that, first, logic appeared in Babylonia and, second, it appeared within a unique legal tradition where all trial decisions must have been transparent, obvious, and provable. The symbolic logic appeared first not in Greece, but in Mesopotamia and this tradition was grounded in the Sumerian/Akkadian jurisprudence.
Impact of traffic routes on the content of trace elements in soils in Warsaw agglomeration
Authors: Komorowski Artur , Szulc Wiesław
Published: August 2017

This article presents the results of a study on the content of selected trace metals (Pb, Zn, Cu, Cd) in soils near the main traffic routes of the Warsaw agglomeration. The aim of the study was to determine the extent of soil contamination with trace metals at different distances from the road (by the side the road and 50 meters away from the road). In the soil 50 m away from the road in Łomianki ‘low contamination’ was found for zinc and ‘elevated content’ for copper according to the IUNG guidelines, but the amounts of the trace elements were not found to exceed the permissible levels as specified in the Regulation of the Minister for the Environment of 1 September 2016.
The effect of wheat straw quality on the rate of its mineralisation in soil
Authors: Tatuśko Natalia , Kosicka-Dziechciarek Donata , Pluta Mateusz
Published: August 2017

The aim of this study was to assess the effect of straw of two spring wheat cultivars, Tybalt – with the culm filled with pith, and Ostka Smolicka – with the hollow culm, added to light textured soil, on the mineralisation rate of organic matter. The incubation experiment was established under laboratory conditions and comprised three experimental combinations: K1 was soil with an addition of pith-filled culms, K2 – soil with an addition of straw with hollow culms, and K0 – the control with no straw added. In all the combinations, mineral fertilisation was applied in the form of urea. Incubation lasted for 14 months. At specific dates the amounts of CO2 released within 24 h and pH values were recorded. The rate of organic matter mineralisation was expressed in mg CO2·d−1. Analyses showed that the addition of straw, both with pith-filled and hollow culms, significantly influenced the mineralisation of organic matter in the first months of incubation. Mineralisation was most intensive in the soil incubated with straw with hollow culms. The large amount of released carbon dioxide in the first days of incubation caused a decrease in pH both in the control soil and in soils with the addition of straw. The change in the soil reaction to its initial value was recorded at day 222 for the soil combination K0 and at day 250 of incubation in soils fertilised with straw.

Published: August 2017

The design and validation of a Compact Crossover Diffuser (CCD) to replace the size-limited radial diffuser and axial de-swirl cascade of an existing Micro Gas Turbine (MGT) is discussed. A CCD strives to combine the performance of a channel diffuser with the operating range and efficiency of a vaneless diffuser. The development of a one-dimensional Mean-Line Code (MLC) is presented, which aids the designer in preliminary design and performance evaluation of the CCD. Design graphs indicating the performance effects of changing the primary design variables are developed and shown. The MLC is numerically validated using Computational Fluid Dynamics (CFD). Good agreement is seen between the MLC and CFD results, predicting the design point PRss(2-4) to within 1.4 %. A CFD optimized CCD was manufactured and tested. Agreement between the CFD and experimental results for PRts(0-4) is within 7.58 % at 106 kRPM. A numerically predicted increase in PRts(0-4) from 3.31, to 3.53, to 3.83 is seen for the vaneless-, MLC optimized-, and CFD optimized-design respectively. An experimental increase of 82.3 % in engine thrust and 80.0 % in total-to-static pressure recovery across the compressor stage was measured when retrofitting the BMT120KS with a new impeller and CCD.

Schoenfeld, BJ, Grgic, J, Ogborn, D, and Krieger, JW. Strength and hypertrophy adaptations between low- vs. high-load resistance training: a systematic review and meta-analysis. J Strength Cond Res 31(12): 3508–3523, 2017—The purpose of this article was to conduct a systematic review of the current body of literature and a meta-analysis to compare changes in strength and hypertrophy between low- vs. high-load resistance training protocols. Searches of PubMed/MEDLINE, Cochrane Library, and Scopus were conducted for studies that met the following criteria: (a) an experimental trial involving both low-load training [≤60% 1 repetition maximum (1RM)] and high-load training (>60% 1RM); (b) with all sets in the training protocols being performed to momentary muscular failure; (c) at least one method of estimating changes in muscle mass or dynamic, isometric, or isokinetic strength was used; (d) the training protocol lasted for a minimum of 6 weeks; (e) the study involved participants with no known medical conditions or injuries impairing training capacity. A total of 21 studies were ultimately included for analysis. Gains in 1RM strength were significantly greater in favor of high- vs. low-load training, whereas no significant differences were found for isometric strength between conditions. Changes in measures of muscle hypertrophy were similar between conditions. The findings indicate that maximal strength benefits are obtained from the use of heavy loads while muscle hypertrophy can be equally achieved across a spectrum of loading ranges.

Published: August 2017

Ductile cast irons are materials with good ductility and toughness, but they are susceptible to high wear rates since they have low hardness. One way to increase their wear resistance is through thermo-reactive diffusion treatments (TRD), in which carbide layers are produced on the surface of the material. In this study, two ductile cast irons (with and without the addition of copper) were treated in a salt bath composed of borax, ferroniobium (16 wt.%) and aluminum (3 wt.%) at 1000°C for 4 h. The XRD and micro-hardness analysis indicated that NbC layers were produced with hardness values higher than 2000 HV. Two methods were used to examine the adherence of the layer to the substrate. In the first method, indentations were performed using Rockwell C scale (VDI 3198). The second method used Vickers micro-hardness indentations (loads 100, 200, and 300 gf) at the interface layer/substrate. In both tests, the layers showed good adhesion to substrates. The 3198 VDI test also showed that the NbC layer produced good toughness. The results of micro-adhesive and micro-abrasive wear tests showed that the layer was very effective in increasing wear resistance.

Published: August 2017

The aeronautics and automotive industries face increasing demands to lower fuel consumption and consequent CO2 emissions. One method of accomplishing this is to use materials with high strength/weight ratio. Alloys of steels using high manganese and aluminum shows promising results, with densities between 10% and 13% lower than those of conventional steels and high strength because of precipitation of κ-carbides. The performance of these alloys can be broadened with use of surface hardening techniques, attached to suitable heat treatment. In this work, the mechanical characteristics of conventional aging were compared with plasma nitrocarburizing in the Fe-31.2Mn-7.5Al-1.3Si-0.9C (wt. %) steel. The layers produced were characterized using optical micrograph and hardness and wear tests. The treatment produced layers with wear resistance superior to that the substrate, which also had its wear resistance increased because of aging. The increase in hardness was about 2× in the surface and 1.2× in the substrate, which resulted in wear resistances 9× higher than a substrate without any treatment.
Presence of Androgen Receptor Variant in Neuronal Lipid Rafts

Published: August 2017

Fast, nongenomic androgen actions have been described in various cell types, including neurons. However, the receptor mediating this cell membrane–initiated rapid signaling remains unknown. This study found a putative androgen receptor splice variant in a dopaminergic N27 cell line and in several brain regions (substantia nigra pars compacta, entorhinal cortex, and hippocampus) from gonadally intact and gonadectomized (young and middle-aged) male rats. This putative splice variant protein has a molecular weight of 45 kDa and lacks an N-terminal domain, indicating it is homologous to the human AR45 splice variant. Interestingly, AR45 was highly expressed in all brain regions examined. In dopaminergic neurons, AR45 is localized to plasma membrane lipid rafts, a microdomain involved in cellular signaling. Further, AR45 protein interacts with membrane-associated G proteins Gαq and Gαo. Neither age nor hormone levels altered AR45 expression in dopaminergic neurons. These results provide the first evidence of AR45 protein expression in the brain, specifically plasma membrane lipid rafts. AR45 presence in lipid rafts indicates that it may function as a membrane androgen receptor to mediate fast, nongenomic androgen actions.

The northeastern North American continental shelf from Cape Hatteras to the Scotian Shelf is a region of globally extreme positive trends in sea surface temperature (SST). Here, a 33-year (1982–2014) time series of daily satellite SST data was used to quantify and map spatial patterns in SST trends and phenology over this shelf. Strongest trends are over the Scotian Shelf (>0.6°C decade–1) and Gulf of Maine (>0.4°C decade–1) with weaker trends over the inner Mid-Atlantic Bight (~0.3°C decade–1). Winter (January–April) trends are relatively weak, and even negative in some areas; early summer (May–June) trends are positive everywhere, and later summer (July–September) trends are strongest (~1.0°C decade–1). These seasonal differences shift the phenology of many metrics of the SST cycle. The yearday on which specific temperature thresholds (8° and 12°C) are reached in spring trends earlier, most strongly over the Scotian Shelf and Gulf of Maine (~ –0.5 days year–1). Three metrics defining the warmest summer period show significant trends towards earlier summer starts, later summer ends and longer summer duration over the entire study region. Trends in start and end dates are strongest (~1 day year–1) over the Gulf of Maine and Scotian Shelf. Trends in increased summer duration are >2.0 days year–1 in parts of the Gulf of Maine. Regression analyses show that phenology trends have regionally varying links to the North Atlantic Oscillation, to local spring and summer atmospheric pressure and air temperature and to Gulf Stream position. For effective monitoring and management of dynamically heterogeneous shelf regions, the results highlight the need to quantify spatial and seasonal differences in SST trends as well as trends in SST phenology, each of which likely has implications for the ecological functioning of the shelf.
CONE: Community Oriented Network Estimation Is a Versatile Framework for Inferring Population Structure in Large-Scale Sequencing Data
Authors: Kuismin Markku O , Ahlinder Jon , Sillanpӓӓ Mikko J
Published: August 2017

Estimation of genetic population structure based on molecular markers is a common task in population genetics and ecology. We apply a generalized linear model with LASSO regularization to infer relationships between individuals and populations from molecular marker data. Specifically, we apply a neighborhood selection algorithm to infer population genetic structure and gene flow between populations. The resulting relationships are used to construct an individual-level population graph. Different network substructures known as communities are then dissociated from each other using a community detection algorithm. Inference of population structure using networks combines the good properties of: (i) network theory (broad collection of tools, including aesthetically pleasing visualization), (ii) principal component analysis (dimension reduction together with simple visual inspection), and (iii) model-based methods (e.g., ancestry coefficient estimates). We have named our process CONE (for community oriented network estimation). CONE has fewer restrictions than conventional assignment methods in that properties such as the number of subpopulations need not be fixed before the analysis and the sample may include close relatives or involve uneven sampling. Applying CONE on simulated data sets resulted in more accurate estimates of the true number of subpopulations than model-based methods, and provided comparable ancestry coefficient estimates. Inference of empirical data sets of teosinte single nucleotide polymorphism, bacterial disease outbreak, and the human genome diversity panel illustrate that population structures estimated with CONE are consistent with the earlier findings

Published: August 2017

Objectives

Objective measurements using built-in smartphone sensors that can measure physical activity/inactivity in daily working life have the potential to provide a new approach to assessing workers’ health effects. The aim of this study was to elucidate the characteristics and reliability of built-in step counting sensors on smartphones for development of an easy-to-use objective measurement tool that can be applied in ergonomics or epidemiological research.

Methods

To evaluate the reliability of step counting sensors embedded in seven major smartphone models, the 6-minute walk test was conducted and the following analyses of sensor precision and accuracy were performed: 1) relationship between actual step count and step count detected by sensors, 2) reliability between smartphones of the same model, and 3) false detection rates when sitting during office work, while riding the subway, and driving.

Results

On five of the seven models, the inter-class correlations coefficient (ICC (3,1)) showed high reliability with a range of 0.956-0.993. The other two models, however, had ranges of 0.443-0.504 and the relative error ratios of the sensor-detected step count to the actual step count were ±48.7%-49.4%. The level of agreement between the same models was ICC (3,1): 0.992-0.998. The false detection rates differed between the sitting conditions.

Conclusions

These results suggest the need for appropriate regulation of step counts measured by sensors through means such as correction or calibration with a predictive model formula in order to obtain the highly reliable measurement results that are sought in scientific investigation.

BACKGROUND AND OBJECTIVES:

National guidelines recommend blood cultures for children hospitalized with presumed bacterial community-acquired pneumonia (CAP) that is moderate or severe. We sought to determine the prevalence of bacteremia and characterize the microbiology and penicillin-susceptibility patterns of positive blood culture results among children hospitalized with CAP.

METHODS:

We conducted a cross-sectional study of children hospitalized with CAP in 6 children’s hospitals from 2007 to 2011. We included children 3 months to 18 years of age with discharge diagnosis codes for CAP using a previously validated algorithm. We excluded children with complex chronic conditions. We reviewed microbiologic data and classified positive blood culture detections as pathogens or contaminants. Antibiotic-susceptibility patterns were assessed for all pathogens.

RESULTS:

A total of 7509 children hospitalized with CAP were included over the 5-year study period. Overall, 34% of the children hospitalized with CAP had a blood culture performed; 65 (2.5% of patients with blood cultures; 95% confidence interval [CI]: 2.0%–3.2%) grew a pathogen. Streptococcus pneumoniae accounted for 78% of all detected pathogens. Among detected pathogens, 50 (82%) were susceptible to penicillin. Eleven children demonstrated growth of an organism nonsusceptible to penicillin, representing 0.43% (95% CI: 0.23%–0.77%) of children with blood cultures obtained and 0.15% (95% CI: 0.08%–0.26%) of all children hospitalized with CAP.

CONCLUSIONS:

Among children without comorbidities hospitalized with CAP in a non-ICU setting, the rate of bacteremia was low, and isolated pathogens were usually susceptible to penicillin. Blood cultures may not be needed for most children hospitalized with CAP.

Published: August 2017

It was carried out an investigation at the central region of Venezuela from January to June 2014 with the aim to determine the prevalence of coccidian Cystoisospora suis in intensive swine herds. For parasitic determination 572 litters were selected with signsof diarrhea. Likewise, 1.712 fecal samples were also collected in mature pigs. Stoolsamples were cultured in a 2.5% potassium dichromate solution and later processedby coprological technique. The results of this investigation indicated that C. suis was observed in 55 herds (82.1%) and 210 litters (36.7%) with the highest prevalence values in first two weeks of age (P < 0.05). Regarding to mature pigs, there was a significant correlation (rho = 0.35; P < 0.05) among oocysts excretion in piglets and sows, suggesting that sows may act as infection sources. Sows parity was statistically correlated with the prevalence values in litters as in lactating sows (P < 0.05). This might indicate that as parity increase, prevalence decreases in these groups. Probably these findings are associated with unknown immunologic mechanisms. It is concluding that C. suis is broadly distributed in Venezuela and it could be controlled by improving conditions sanitary herd, however, non elucidated immunologic mechanisms might be involved in the protozoa transmission cycle.

One of the main difficulties presented in surgical practice, is the restoration of the integrity of the tissues that are affected by the pathology or the surgical technique performed for its resolution. Currently, techniques and treatments are developed focused to improve scarring processes tissue and promote tissue regeneration; one of them is Autologous Platelets Concentrate (APC). The aim of the present study was evaluate the blood collection and processing technique for obtaining APC in a lagomorph model. New Zealand male rabbits (n=10), with weights ranging from 3 to 3.8 kg, were used as experimental model. The blood sample of each animal was obtained by puncture of the jugular vein into tubes with sodium citrate and centrifuged at 120 g for 5 minutes. The levels oferythrocytes, leukocytes and platelets after the centrifugation process presented statistically significant differences (P < 0.05) compared to whole blood. The results of this study support the conclusion that the development of a APC for leporidae species is feasible, obtaining platelets without morphology alterations after a single centrifugation cycle.

This study evaluated the inclusion of oregano essential oil (OEO, Lippia origanoides Kunth) in diets enriched with polyunsaturated fatty acids (PUFAs) on productive performance of laying hens, lipid profile and oxidative stability of eggs during storage. 144 hens were distributed in one of four treatments with six replicates in order to evaluate the effect of the type of oil used in the diet (palm or fish) and the inclusion of OEO on the production variables, along with the ethereal extract, lipid profile and malonaldehyde concentration (MDA), using a completely randomized factorial design with the repeated measures of days of storage (0, 30 and 60 days at 4° C). Results show that the type of oil and the OEO did not affect productive performance of layers (P > 0.05). PUFA concentration increased in 16.8% in diets with fish oil in 16.8%, where the DHA also increased by1.4% (P < 0.05), increasing the MDA concentration in egg (MDA 41.6 ng/g yolk), while supplementation of OEO at a level of 100 g/ton improved oxidative stability during storage (MDA 31.1 ng/g yolk). During storage the concentration of MDA in the yolk increased with time reaching 38 ng/g yolk at 60 days. The OEO showed potential as a natural antioxidant in the diet of layers hens improving the oxidative stability of eggs stored at 4°C up to 60 days.

ABSTRACT This study aimed to understand the relationship of morphological characteristics and actual evapotranspiration of forage cactus clones with their productive capacity under different water regimes. The data used in this study were collected between the years 2012 and 2013, in Serra Talhada, State of Pernambuco. The clones Sertânia IPA - IPA, Miúda - MIU and Orelha de Elefante Mexicana - OEM were submitted to three irrigation depths (2.5, 5.0 and 7.5 mm) and three irrigation intervals (7, 14 and 28 days). Cladode and plant morphology, accumulated actual evapotranspiration and yield were obtained at the moment of harvest. Pearson’s correlation matrix was elaborated and, in the sequence, multicollinearity, canonical and path analysis were applied. There was no correlation of yield with the soil water supply and actual evapotranspiration of the clones (p > 0.05). Forage cactus yield was more associated with peculiarities of the morphological characteristics of the clones than with the different soil water supplies or the crop actual evapotranspiration. However, regardless of the water regime and clone, the vigor of the basal cladodes was highly decisive for the expression of the forage cactus productive capacity.

ABSTRACT Polycultures from broadleaves with tuberoses are being used in vegetable crop production systems in the semiarid region of Potiguar. The challenge is to determine whether these systems are productively viable when fertilized with organic matter produced by spontaneous species of the Caatinga biome. The objective of this study was to evaluate the agro-economic performance of arugula (A), carrot (C), and coriander (Co) polycultures fertilized with hairy woodrose biomass incorporated into the soil under different population densities among the component crops. The experimental design was a randomized complete block with four replications, with the treatments arranged in a 4 × 4 factorial scheme, from the combination of four amounts of hairy woodrose biomass incorporated into the soil (7.5, 15.0, 22.5, and 30.0 t ha-1 on a dry matter basis), with four population densities (20A-50C-20Co%, 30A-50C-30Co%, 40A-50C-40Co%, and 50A-50C-50Co% of the recommended population in the single crop). The efficiency of polycultures was evaluated through indexes and agro-economic indicators. The most productive agro-economic performance was obtained with a biomass of 18.21 t ha-1 of hairy woodrose incorporated in the soil and a population density of 50A-50C-50Co%.

ABSTRACT Aiming to evaluate different wastewaters in the anaerobic co-digestion (ACoD) of hatchery wastes, a batch test was conducted in bench horizontal digesters. At the end of the process, the potential production of biogas and methane was calculated as well as the chemical composition (macro- and micronutrients) of the effluent and the concentrations of methane and carbon dioxide gas at 60 days. The monitoring of the process included observations of the reduction of the organic carbon, chemical oxygen demand, and total (TS) and volatile solids (VS), as well as the variation of pH and electrical conductivity (EC). The results showed that the mixing between the hatchery fresh waste and swine wastewater (T4) and among fresh hatchery waste, water from the first anaerobic pond of the hatchery and swine wastewater (T5) represent significant sources of renewable energy and thereby greater potential for biogas production (192.50 and 205.0 L biogas per kg of VS added to T4 and T5, respectively). The average concentration of methane in the biogas varied from 72 to 77% among the treatments. For all treatments, reductions were observed in TS and VS and increases in pH and EC. It was concluded that the energy recovery from hatchery wastes is favoured by the addition of swine wastewater in the ACoD process.

O estudo 1 contou com a participação de duzentas mães divorciadas de cidades do estado da Paraíba, com idade média de 35 anos (DP = 9,06). Por meio de uma Análise Fatorial Exploratória, visualizou-se uma estrutura unifatorial do inventário, com um índice de consistência interna de 0,83. O estudo 2 contou com 189 mães divorciadas, residentes em municípios paraibanos, com idade média de 37 anos (DP = 10,69). Nesse estudo, uma Análise Fatorial Confirmatória sugeriu uma estrutura unifatorial da medida [χ² = 141,05, χ²/ gL = 4,03, GFI = 0,87, CFI = 0,88, TLI = 0,85, RMSEA (IC90% = 0,10 - 0,14) = 0,12, CAIC = 265,89 e ECVI = 0,96]. Conclui-se que o Inventário em questão é uma medida que apresenta características psicométricas que permitem seu uso com cautela em estudos futuros.

Abstract To characterize and compare the spelling performance of private and public students. Three hundred 1st-5th graders from public and private schools in the city of Marília, São Paulo, Brazil, were evaluated, totalizing 30 students from each grade, respectively. Collective and individual versions of the Pró-Ortografia test (a renowned Brazilian spelling test) were administered. There were significant inter-group differences indicating that private school students achieved higher performance. The mean values of correct answers of higher grade level students were statistically greater than those of the lower grade level students. The results indicated that the mean values of correct answers of all versions of the spelling test administered increased across grades for both private and public school students. However, the data evaluated showed that private school students attained higher spelling performance than public school students from the 2nd grade onwards.

Resumen Las desigualdades entre mujeres y hombres se siguen manteniendo en las organizaciones a pesar de los esfuerzos políticos y sociales realizados para afrontar este fenómeno. Las certificaciones de igualdad son reconocidas en España como uno de los instrumentos políticos diseñados para combatir estos desequilibrios de género a partir de la promulgación de la Ley Orgánica nº 3/2007 para la igualdad efectiva de mujeres y hombres. Este artículo tiene como objetivo identificar el enfoque desde el que las organizaciones, públicas y privadas, responsables de la promoción de certificaciones de igualdad de género, están respondiendo a la aplicación del mainstreaming de género. Aplicamos un análisis de contenido a partir del estudio de publicaciones relativas a las certificaciones. Los resultados muestran que estas certificaciones se conceden, en muchos casos, ignorando indicadores esenciales para implementar el enfoque de género. Igualmente, se impulsa su uso lucrativo como marca de calidad organizativa.

ABSTRACT Objective: To evaluate the shear bond strength of lingual orthodontic brackets with resin or metal pads, the location of bond failure and the adhesive remnant index (ARI). Methods: A total of 40 extracted upper premolars were randomly divided into two groups of 20 each: bonding with brackets having (1) pads with extended resin directly on the lingual surface of teeth, and (2) pads with metal custom base on the lingual surface of teeth. The debonding force was measured with an Instron universal testing machine. A Student’s t-test was used to assess the difference between groups (α = 0.05). Results: The results showed a significant difference between the groups (p < 0.001). The shear bond strength of metal pads was significantly higher than resin pads. Conclusions: Within the limitations of this in vitro study, it was concluded that the bond strength of lingual brackets with metal pads was higher than that of brackets with composite resin pads, due to the metal part being a single unit and welded. The failure location in the region between the bracket and the resin pad affected a higher percentage of the resin pads than the metal pads.

ABSTRACT Introduction: Many patients seeking orthodontic treatment already have incipient enamel lesions and should be placed under preventive treatments. The aim of this in vitro study was to evaluate the effect of CPP-ACP paste and CO2 laser irradiation on demineralized enamel microhardness and shear bond strength of orthodontic brackets. Methods: Eighty caries-free human premolars were subjected to a demineralization challenge using Streptococcus mutans. After demineralization, the samples were randomly divided into five equal experimental groups: Group 1 (control), the brackets were bonded without any surface treatment; Group 2, the enamel surfaces were treated with CPP-ACP paste for 4 minutes before bonding; Group 3, the teeth were irradiated with CO2 laser beams at a wavelength of 10.6 µm for 20 seconds. The samples in Groups 4 and 5 were treated with CO2 laser either before or through CPP-ACP application. SEM photomicrographs of a tooth from each group were taken to observe the enamel surface. The brackets were bonded to the buccal enamel using a conventional method. Shear bond strength of brackets and ARI scores were measured. Vickers microhardness was measured on the non-bonded enamel surface. Data were analyzed with ANOVA and Tukey test at the p< 0.05 level. Results: The mean shear bond strength and microhardness of the laser group were higher than those in the control group and this difference was statistically significant (p< 0.05). All groups showed a higher percentage of ARI score 4. Conclusion: CO2 laser at a wavelength of 10.6 µm significantly increased demineralized enamel microhardness and enhanced bonding to demineralized enamel.

ABSTRACT Introduction: Maxillary constriction is a dentoskeletal deformity characterized by discrepancy in maxilla/mandible relationship in the transverse plane, which may be associated with respiratory dysfunction. Objective: The objective of this study was to evaluate the skeletal effects of RME on maxillary and nasal transverse dimensions and compare the differences between males and females. Methods: Sixty-one mouth-breathers patients with skeletal maxillary constriction (35 males and 26 females, mean age 9.6 years) were included in the study. Posteroanterior (PA) radiographs were taken before expansion (T1) and 3 months after expansion (T2). Data obtained from the evaluation of T1 and T2 cephalograms were tested for normality with the Kolmogorov-Smirnov method. The Student’s t-test was performed for each measurement to determine sex differences. Results: RME produced a significant increase in all linear measurements of maxillary and nasal transverse dimensions. Conclusions: No significant differences were associated regarding sex. The RME produced significant width increases in the maxilla and nasal cavity, which are important for treatment stability, improving respiratory function and craniofacial development.

RESUMO Objetivo Comparar a evolução das vocalizações em bebês prematuros e a termo, com e sem risco ao desenvolvimento, analisando as possíveis relações entre variáveis sociodemográficas, obstétricas e psicossociais com as vocalizações. Método A amostra foi composta por 30 bebês com idade entre os 3 meses e 1 dia aos 4 meses e 29 dias (fase 1) e 6 meses e 1 dia aos 7 meses e 29 dias (fase 2), de ambos os gêneros, com idade gestacional inferior a 37 semanas (grupo de prematuros) e superior a 37 semanas (grupo a termo). Para a coleta de dados, utilizaram-se os protocolos Indicadores de Risco ao Desenvolvimento Infantil, o teste Denver II e entrevista sobre a experiência da maternidade com dados sociodemográficos, obstétricos e psicossociais, além de filmagem da díade mãe-bebê nas duas fases da pesquisa. Os dados das filmagens foram analisados no software EUDICO Linguistic Anotador (ELAN) e os resultados analisados estatisticamente no software STATISTICA 9.0. Resultados Quanto maior o número total de vocalizações do bebê e quanto mais vocalizações das mães com manhês, maior o número de Indicadores de Risco ao Desenvolvimento Infantil presentes. Também se percebeu aumento significativo de vocalizações sem manhês na fase 2 pesquisada. As variáveis sociodemográficas, idade gestacional, peso ao nascer, escolaridade materna e o Critério Brasil não incidiram diretamente no nível de vocalizações dos bebês. Conclusão A análise das vocalizações dos bebês associou-se ao risco ao desenvolvimento, assim como os Indicadores de Risco ao Desenvolvimento Infantil, na fase 1 pesquisada, o teste Denver-Linguagem é mais efetivo na fase 2. Não houve influência das variáveis sociodemográficas na fase estudada.

RESUMEN Los beneficios de la diversificación internacional se han visto modificados por el cambio continuo de las correlaciones entre los mercados. La inversión inmobiliaria presenta un elevado potencial como activo diversificador en un portafolio. El objetivo del presente trabajo es analizar la diversificación combinando la inversión en REIT con renta variable, para un inversor de Brasil. Para ello construimos carteras óptimas out-of-sample mediante predicciones de volatilidad, correlaciones y rendimientos utilizando los métodos DCC y VAR-DCC para el índice Ifix y los ETF BOVA11 y SPDR S&P500, durante el período de 1 de diciembre de 2014 a 30 de octubre de 2015. Nuestros resultados muestran que la aproximación VAR-DCC mejora ligeramente las aproximaciones Plug-in y DCC, y la cartera Naïve.

Abstract Hepatozoon species are the most common intracellular hemoparasite found in reptiles. Hepatozoon caimani, whose vectors are Culex mosquitoes, has been detected in a high prevalence among caimans in Brazil by blood smears examinations. The present work aimed to detect and characterize the Hepatozoon spp. found in 33 caimans (24 free-ranging and 9 captive; 28 males and 5 females) (Caiman crocodilus yacare) sampled at Poconé, North Pantanal, state of Mato Grosso, Brazil, using blood smears examinations and molecular techniques. Hepatozoon spp.-gametocytes were found in 70.8% (17/24) and 88.8% (8/9) of blood smears from free-ranging and captive caimans, respectively. Hepatozoon spp. 18S rRNA DNA was found in 79.2% (19/24) and 88.8% (8/9) of free-ranging and captive caimans, respectively. Comparative analysis of parasitized and non-parasitized erythrocytes showed that all analyzed features were significantly different (P<0.05) for both linear and area dimensions. Phylogenetic analysis based on 18S rRNA sequences grouped the Hepatozoon spp. sequences detected in the present study together with H. caimani, recently detected in caimans in southern Pantanal.
