title: The (un)expected in describing and understanding sociolinguistic complexity in translingual practices of deaf students

description: ABSTRACT This article presents a translingual and multimodal analysis of an interaction between deaf students attending a Portuguese course in order to reflect about the unexpected use of resources in the event in question. For this purpose, a set of ethnographic recordings was used to describe and analyze the interaction event in relation to the different contextual materials and normativity centers orienting the participants’ actions. The analyzed event revealed different scales in conflict in which the complexity and unpredictability of linguistic functioning referred to the multi-layered aspects of the language that were mobilized and, at the same time, to the field of language ideologies. Thus, the (un)expected, when explained, proved to be a crucial key to describing and constructing a more comprehensive understanding of how language works in the classroom with deaf students, with implications for research on deaf education affiliated to the applied field of language studies and for teacher training.

title: SYNTHESIS OF TOLUENE DIISOCYANATE URETHANE PREPOLYMER USING CASTOR OIL AND EVALUATION OF MECHANICAL PROPERTIES

description: This research is the synthesis of urethane prepolymer cast elastomer which had been produced using toluene diisocyanate and castor oil to replace the synthetic polyol, from petroleum origin, and the evaluation of mechanical properties of the polyurethane. The focus was to replace polyol from petroleum to vegetable material looking for renewable resources. The reactions occurred in a pilot reactor considering the process temperature of 70 °C and 0.5 bar of pressure. After the reactions, all prepolymers reacted with the chain extender to cast in sheet molds for mechanical properties. The chains extenders chosen to react with the prepolymers were 4,4’-methylenebis(2-chloroaniline) and castor oil. The better results achieved 65 Shore A as hardness, 35% as rebound resilience, 36.22 mm3 as abrasion resistance, 570.12 psi as tensile strength, 325.39% as elongation and 29.53 kN m-1 as tear resistance; achieved using a blend between castor oil and polytetramethylene ether glycol with 2000 g mol-1 as molecular weight. Thought the mechanical results tests, the castor oil can replace the synthetic polyol depending on applications which did not require a high tensile strength and tear resistance, such as rolls for graphics and cellulose processes, billets seals, cushions and general parts used for industrial segment.

title: VO2max-Based Physical Fitness Categories in a Brazilian Population with Supposed High Socioeconomic Status and without Structural Heart Disease

description: Abstract Background The most widely used data for cardiorespiratory fitness (CRF) referrals are from the Cooper Clinic, which uses calculated maximal oxygen uptake (VO2max) values. Objective To develop CRF values from cardiopulmonary exercise testing (CPX) in a Brazilian population with high socioeconomic level and free of structural heart disease. VO2max testing results were compared with the Cooper Clinic and FRIEND Registry data. Methods CPX data from consecutive individuals between January 1,2000, and May 31,2016 were used in this study. Inclusion criteria were: VO2max by a pre-specified definition. We built a CRF chart according to VO2max percentiles: very poor (≤20%), poor (20-40%), fair (40-60%), good (60-80%), excellent (80-90%), and superior (≥90%). Kappa correlation was used to analyze our data in comparison with that of the other two databases. Statistical tests with p&lt;0.005 were considered significant. Results Final cohort included 18,186 tests: 12,552 men, 5,634 women (7–84 years). The most recurrent response was “good” (20.2%). There was a mean difference in weight, height, body mass index (BMI), and age in the CRF chart. An inverse correlation existed between VO2max and age, weight, and BMI. Using a linear regression and these variables, a predictive equation was developed for VO2max. Our findings differed from that of the other databases. Conclusion We developed a classification for CRF and found higher values in all classification ranges of functional capacity in contrast to the Cooper Clinic and FRIEND Registry. Our findings offer a more accurate interpretation of ACR in this large Brazilian population sample when compared to previous standards based on the estimated VO2max.

title: In bocca al lupo! / Hals und Beinbruch! A contrastive analysis of wish formulae in German and Italian

description: ABSTRACT Routine formulae are significant linguistic phenomena in the areas of foreign language teaching and bilingual lexicography. Nevertheless, few contrastive analysis of these units exist for the German-Italian language pair. The aim of this paper is a pragmalinguistic contrastive analysis of ‘wishing formulas’. The main criterion of contrasting is the pragmatic value of the units, i.e. the speech acts that can be performed through them, as well as the situational and sociolinguistic features of the formulae and the productivity of certain syntactic-lexical patterns in German and Italian. Equivalences and differences between groups of formulae as well as between the individual units of both languages are identified.

title: Optimization of the Extragranular Excipient Composition of Paracetamol Tablet formulation using the Quality by Design Approach

description: Abstract The purpose of this study is to optimize the composition of extragranular excipients (EGE) and mixing time of granules with EGE of paracetamol tablet formulation using Design of Experiments (DoE) approach. The effect of the composition of EGE and the mixing time of granules with EGE on granule and tableting properties of paracetamol tablet formulation was investigated using a combined model of mixture and process factors (Design-Expert 12). A total of 18 tablet formulations were manufactured by wet granulation using varying compositions of EGE and varying mixing time. Granule and tablet properties of each formulation were evaluated as response variables for the design, data generated were fitted into models and analysed to generate a design space that was used for optimization studies. The proposed EGE composition as predicted by the design was confirmed and validated after preparation and evaluation of the granule and tablet properties. The optimized composition for the EGE that yielded granules and tablets of desirable characteristics was found to be maize starch (5 %), talc (4.9 %) and magnesium stearate (0.1 %) with a mixing time of 2 min. The tablets produced with the optimized composition had better mechanical strength and disintegration time than the formulation prepared using an existing formula of maize starch (7.8 %), talc (2 %) and magnesium stearate (0.2 %) that were obtained using the One Variable at a Time (OVAT) approach. This study confirmed the relevance of quality by design in development of pharmaceutical formulations.

title: A new species of the sharpshooter genus Hanshumba (Insecta: Hemiptera: Cicadellidae: Cicadellini) from the Mantiqueira mountain range, southeastern Brazil, associated with olive orchards

description: ABSTRACT A new species of Hanshumba Young, 1977 is described and illustrated from the Mantiqueira mountain range (southeastern Brazil), municipalities of Wenceslau Braz (state of Minas Gerais) and São Bento do Sapucaí (state of São Paulo). The new taxon is associated with olive orchards and is considered a potential vector of the bacterium Xylella fastidiosa. This bacterium causes a serious disease known in Brazil as olive leaf desiccation syndrome. Hanshumba mariae sp. nov. can be distinguished from the other five known species of the genus by the following combination of features: (1) apical third of ventral margin of male pygofer with small inner process bearing setae; (2) male abdominal segment X (anal tube) without processes; (3) style with apex narrow, obtuse, not foot-shaped; (4) aedeagus with distinct dorsal lobe along basal two-thirds and with apical portion expanded, bearing dorsal projection; (5) paraphyses with distal pair of rami forceps-like, their basal halves divergent from each other, distal halves approximately parallel, apices acute; (6) female sternite VII with posterior margin shallowly emarginate, bearing slight median lobe; and (7) valvula II of ovipositor with approximately 15 low teeth. Both males and females of the new species are described in detail. A key to the six known species of the genus is provided.

title: SPORTS MANAGEMENT RESEARCH: ANALYSIS OF SCIENTIFIC DEVELOPMENT IN PORTUGAL (2008-2017)

description: ABSTRACT Scientific research in the field of sports management and its respective academic improvement has been pointed out and recognised by several authors as the path to follow for a better understanding of its importance in the global development of sport, as well as in the improvement of academic curricula and skills of sports managers. This study aims to analyse the scientific and academic production of three Portuguese public universities, being this the main source and origin of the knowledge generated over the last decades. Methodologically, we analysed 193 master dissertations successfully completed between 2008 and 2017 available in institutional scientific repositories, as well as in the national library. The results point to a growth of scientific knowledge in Portugal, validated by the considerable evolution in the number of completed works in distinct areas in sports management, mainly in the scope of planning and strategy, human resources and sociological aspects, which helps to reinforce its multidisciplinary and differentiating character. The data obtained allow us to expose a considerable part of the knowledge produced in Portugal, thus contributing to the strengthening of some areas and future research in sports management, given that it is crucial to aggregate the existing knowledge by enhancing new paths and future opportunities. We conclude that research in Portugal reflects the global growth of scientific knowledge and the increasing interest in sports management, both at qualitative and quantitative levels, while also following international concerns and trends.

title: Bat species diversity from Reserva Ecológica de Guapiaçu, Rio de Janeiro, Brazil: a compilation of two decades of sampling

description: ABSTRACT Reserva Ecológica de Guapiaçu (REGUA) is a private, protected area inside a remnant of the Atlantic Forest with high biodiversity. Although the bats of the reserve have been sampled for more than two decades, few studies have been published about them. Based on a compilation of data from several surveys, we present an updated list of the bat species there and compare it with surveys from other locations in the Atlantic Forest. From August 1998 to September 2021, at least 194 sampling nights were carried out at REGUA by different research groups from various institutions, totaling 448,092 m2.h of sampling. A total of 4,069 individuals were captured, belonging to 47 species and six families. Additionally, our results indicate that it is possible that some species that occur at REGUA have not been recorded yet. REGUA has the greatest number of bat species known for the Atlantic Forest. This most likely results from the fact that the reserve includes large areas of mature, continuous forest connected with other protected areas in the State of Rio de Janeiro. Another factor contributing to the high diversity of bat species at REGUA is that the area has been intensely sampled for many years. Given that the bat assemblage there appears to be a good proxy to ascertain the ecological patterns of biodiversity in well-preserved forests, we consider REGUA to be an important area for long-term ecological research. The basic knowledge about the ecological interactions of bats with different food resources and zoonotic microorganisms offers a unique opportunity to carry out research in several areas of knowledge, making it possible to address questions about bat assemblage structure, bat-parasite ecology, competition, niche partitioning, and other related studies.

title: The role of neuroimaging in the determination of brain death

description: Abstract Brain death is the irreversible cessation of all brain function. Although protocols for its determination vary among countries, the concept of brain death is widely accepted, despite ethical and religious issues. The pathophysiology of brain death is related to hypoxia and ischemia in the setting of extensive brain injury. It is also related to the effects of brain edema, which increases intracranial pressure, leading to cerebral circulatory arrest. Although the diagnosis of brain death is based on clinical parameters, the use of neuroimaging to demonstrate diffuse brain injury as the cause of coma prior to definitive clinical examination is a prerequisite. Brain computed tomography (CT) and magnetic resonance imaging (MRI) demonstrate diffuse edema, as well as ventricular and sulcal effacement, together with brain herniation. Angiography (by CT or MRI) demonstrates the absence of intracranial arterial and venous flow. In some countries, electroencephalography, cerebral digital subtraction angiography, transcranial Doppler ultrasound, or scintigraphy/single-photon emission CT are currently used for the definitive diagnosis of brain death. Although the definition of brain death relies on clinical features, radiologists could play an important role in the early recognition of global hypoxic–ischemic injury and the absence of cerebral vascular perfusion.
