Assessing the Vulnerability and Adaptive Capacity of Rural Farmers to Climate Change in Girei Local Government Area, Adamawa State, Nigeria
Authors: AZ Ambrose , Mohammed BY
Published: July 2020

This study was formulated to evaluate the climatic characteristics and to determine rural farmers’ vulnerability and adaptive capacity to climate change in Girei Local Government Area. Forty-one years records of temperature and rainfall of the growing season were used for the study. Additionally, farmers’ responses regarding their vulnerability and adaptive capacity to climate change were obtained through questionnaire administration. The use of Functional relationship as well as vulnerability and adaptive capacity indices analysis were employed in analyzing the data. Results show that majority of the rural communities studied (six out of seven) were found to be highly vulnerable (with indices ranging from 0.63 to 0.83) climate change. Only one was moderately vulnerable (0.58). Exposure to climate vagaries was discovered to make farmers most vulnerability to climate change, followed by their adaptive capacity and then their sensitivity to environmental hazards social violence. All the communities were found to possess moderate capacity to cope with climate change effects. This is owing to their wealth accumulation, access to farm inputs, irrigation potentials, literacy level and infrastructural and institutional availability. It was recommended that the rural farmers needed to be provided with available farm inputs and access to credit facilities to enable them cushion the impacts of climate change. Adequate infrastructures and institutions good roads, power supply, healthcare and veterinary services should also be made available to them.

Authors: Agada IO , Sombo T , Utah EU
Published: July 2020

This study aims at modeling net radiation conditioned on wind speed in Port Harcourt using the stochastic (Markov chain model) approach. Thirty-four (34) years data (1977-2010) on daily maximum and minimum relative humidity, maximum and minimum air temperature, solar irradiance and wind speed were sourced from the International Institute of Tropical Agriculture (IITA) and used in the analysis. A two – state (surplus net radiation conditioned on high wind speed and surplus net radiation conditioned on low wind speed) Markov Chain model was developed and used in the course of this work. The result revealed that net radiation is surplus all through the year and monthly steady state probabilities (long run dependence) of surplus net radiation conditioned on low wind speed dominate all through the year. Further analysis with the model showed that surplus net radiation conditioned on low wind speed would occur for 2.44 days and surplus net radiation conditioned on high wind speed for 1.69 days on the average, resulting to a hot weather and climate
Isotopically Enriched 192Os Target Preparation using the Electron-gun Beam Method at Target Preparation Laboratory, Daresbury, UK.
Authors: Daniel T
Published: July 2020

In this work, we have discussed a novel electron gun beam method used for the preparation of an Osmium foil sample at Daresbury Target Preparatory Laboratory, UK, which was used during the 192Os(18O, 16O)194Os 2 neutron transfer reaction at IFIN-HH Bucharest. The successful measurement of gamma energies associated with the 194Os isotopic nucleus recorded from the experiment with the high resolution HPGe detectors from this clean target of 192Os showed that this method has proven very efficient in preparing the most difficult osmium target which other methods like the sputtering, thermal evaporation could not get it prepared due to the high melting point of about 3000 0C found in the Osmium foil.

Published: July 2020

Hypertension is that the most noteworthy risk factor for cardiovascular diseases and stroke. Dietary and lifestyle changes play the foremost part to decrease the hazard of hypertension and other related wellbeing complications. Angiotensin Converting Enzyme (ACE) inhibitors play a major role in treating hypertension. Annapavala chendhuram is a herbo – mineral Siddha formulation comes under the type of 32 internal medicines of Siddha. Hypolipidemic activity of Annapavala chendhuram has been proven by some research studies. Hence, the purpose of the present study was to evaluate the ACE inhibition activity on Annapavala chendhuram by using an in-vitro assay. The ACE inhibition assay was evaluated by UV Spectrophotometry technique based on the hydrolysis of histidyl-hippuryl-leucine (HHL) by ACE. About 50µL test sample with varying concentration (100- 500 µg/ml) along with standard captopril (100µg/ml) added with 50µL of ACE and some process had continued. The present study indicates that the test drug Annapavala chendhuram was effective in inhibiting the enzyme ACE dose-dependently. Maximum percentage inhibition of about 53.24±8.403% was observed at 500μg/ml when compared to that of the Captopril, a standard ACE enzyme inhibitor agent with the maximum inhibition 86.98 ± 6.375 at the concentration of 100μg/ml. It was concluded that the test drug Annapavala chendhuram possess significant anti-hypertensive property in protein denaturation assay. So, further in-vitro evaluation of ACE inhibitory activity on Siddha herbal preparations and clinical trials will be the need of the hour.

Published: July 2020

Background: Turkey has a marked increase in the proportion of female medical students and graduates doctors compared to males. However, females are still underrepresented in some disciplines and grouped in other branches of medicine. It is essential to regularly assess the medical students' trends toward the specialty and avoid the shortage and maldistribution in some critical specialties. This study aims to investigate the gender differences in Turkish medical students’ specialty preferences and influencing factors.

Methods: A descriptive cross-sectional study carried out among final year students at the Bezmialem Vakif University (BVU), Faculty of Medicine in Istanbul, Turkey. Data collected from March to April 2018 using a pre-tested self-administered questionnaire included socio-demographic characteristics of the population, first choices for specialization, and the factors influencing those choices. An independent sample t-test performed to test the gender differences in different influencing factors. Data were analyzed using SPSS version 16.

Results:  A total of seventy (70) students (response rate of 69.5 %) included in the data analysis. The mean age of total respondents was 24.9 ± 0.96 (ranged 23-27), and the male to female ratio of students was approximately 1:1.4. Out of nineteen (19) factors, statistically significant gender differences noted in the mean scores of six factors. Male students were more influenced by family expectations (2.76 ± 0.87, p=0.008), geographical consideration (2.97 ± 0.91, p=0.053), and high income expectations (2.90 ± 0.90, p=0.024) compared to female students. However, female students were more influenced by personal interests (3.61 ± 0.49, p=0.041), personality characteristics (3.59 ± 0.55, p=0.010) and malpractice (2.73 ± 1.03, p=0.015) compared to male students.

Conclusion: There is a significant difference between the sexes in terms of priorities; family, income, and geographical distribution significantly impacted on men, while women were more concerned with lifestyle, well-being and avoiding responsibility.

Published: July 2020

The wastewater treatment plants (WWTP) treat the water from domestic and industrial use so that its discharge, once it passes through them, is harmless to the environment. However, large amounts of energy are necessary to carry out this process. Therefore, energy and process optimization are a key issue within these type of plant. One of the possibilities within the WWTPs is the recovery of hydraulic energy. This paper presents alternatives for the recovery of hydraulic energy, through the use of hydraulic micro-machinery such as PATs or hydrostatic pressure wheels. This type of machinery is capable of recovering a part of that energy that until now it was not possible to recover, in a more economical way and assuming an improvement for plants that have the possibility of installing it. In the here described case study, savings of over 4% were achieved with periods of return on investment of less than 5 years.

Published: July 2020

Equipping new teachers in today’s society is a noble and challenging task. Of late, many additional licensing standards for teachers create additional responsibilities for universities that provide pedagogy, knowledge, and content for teacher candidates. Identification of best practices that support teacher candidates on the Educative Teacher Performance Assessment (edTPA) is of interest to many teacher education programs. The purpose of this research was to analyze whether incorporating a mock edTPA had beneficial results on the passage of the edTPA. This study spanned fourteen ten-week quarters and included 688 teacher candidates who were preparing to become certificated teachers at a university in Washington State. The questions that were posited were: a) Does a capstone class requiring a mock edTPA benefit students? b) Which edTPA rubrics are the most challenging, and why are they challenging? This research study found that adding a mock edTPA prior to the student teaching experience did not produce a statistically significant difference in scores when compared to the group who received an embedded curriculum. When comparing the two different time periods, the passing rate was not significantly different and there was little difference in the mean scores of both groups.

Abstract. Direct measurements of NOx, CO and aromatic volatile organic compound (VOC) (benzene, toluene, C2-benzenes and C3-benzenes) flux were made for a central area of Beijing using the eddy-covariance technique. Measurements were made during two intensive field campaigns in central Beijing as part of the Air Pollution and Human Health (APHH) project, the first in November–December 2016 and the second during May–June 2017, to contrast wintertime and summertime emission rates. There was little difference in the magnitude of NOx flux between the two seasons (mean NOx flux was 4.41 mg m−2 h−1 in the winter compared to 3.55 mg m−2 h−1 in the summer). CO showed greater seasonal variation, with mean CO flux in the winter campaign (34.7 mg m−2 h−1) being over twice that of the summer campaign (15.2 mg m−2 h−1). Larger emissions of aromatic VOCs in summer were attributed to increased evaporation due to higher temperatures. The largest fluxes in NOx and CO generally occurred during the morning and evening rush hour periods, indicating a major traffic source with high midday emissions of CO, indicating an additional influence from cooking fuel. Measured NOx and CO fluxes were then compared to the MEIC 2013 emissions inventory, which was found to significantly overestimate emissions for this region, providing evidence that proxy-based emissions inventories have positive biases in urban centres. This first set of pollutant fluxes measured in Beijing provides an important benchmark of emissions from the city which can help to inform and evaluate current emissions inventories.

Abstract. The size distribution of amino acids (AAs) in atmospheric particles determines the atmospheric allergenicity, which may have deleterious effects on human health. This paper explores the use of compound-specific δ15N patterns of hydrolyzed amino acid (HAA), δ15N values of total hydrolyzed amino acid (THAA), degradation index (DI), and the variance within trophic AAs (ΣV) as markers to examine the sources and processing history of different sizes particle in the atmosphere. 2-weeks of daily aerosol samples from five sampling sites in the Nanchang area (Jiangxi Province, China) and samples of main emission sources of AAs in aerosols (biomass burning, soil and plants) were collected (Zhu et al., 2020). Here, we measured the concentrations and δ15N values of each HAA in two size segregated aerosol particles (> 2.5 μm and PM2.5). Our results showed that the average concentrations of THAA in fine particles was nearly 6 times higher than that in coarse particles (p
Ice crystal characterization in cirrus clouds II: radiometric characterization of HaloCam for the quantitative analysis of halo displays
Authors: Forster Linda , Seefeldner Meinhard , Baumgartner Andreas , Kölling Tobias , Mayer Bernhard
Published: July 2020

Abstract. We present a procedure for geometric, spectral, and absolute radiometric characterization of the weather-proof RGB camera HaloCamRAW and demonstrate its application in a case study.
This characterization procedure can be generalized to other RGB camera systems with similar field of view.
HaloCamRAW is part of the automated halo observation system HaloCam and designed for the quantitative analysis of halo displays.
The geometric calibration was performed using a chessboard pattern to estimate camera matrix and distortion coefficients.
For the radiometric characterization of HaloCamRAW, the dark signal and vignetting effect were determined to correct the measured signal.
Furthermore, the spectral response of the RGB sensor and the linearity of its radiometric response were characterized.
The absolute radiometric response was estimated by cross calibrating HaloCamRAW against the completely characterized spectrometer of the Munich Aerosol Cloud Scanner (specMACS).
For a typical measurement signal the relative (absolute) radiometric uncertainty amounts to 2.8 % (5.0 %), 2.4 % (5.8 %), and 3.3 % (11.8 %) for the red, green, and blue channel, respectively.
The absolute radiometric uncertainty estimate is larger mainly due to the inhomogeneity of the scene used for cross calibration and the absolute radiometric uncertainty of specMACS.
Geometric and radiometric characterization of HaloCamRAW were applied to a scene with a 22∘ halo observed on 21 April 2016.
The observed radiance distribution and 22∘ halo ratio compared well with radiative transfer simulations assuming a range of ice crystal habits and surface roughness values.
This application demonstrates the potential of developing a retrieval method for ice crystal properties, such as ice crystal size, shape, and surface roughness using calibrated HaloCamRAW observations together with radiative transfer simulations.
Use of an Unmanned Aircraft System to Quantify NOx Emissions from a Natural Gas Boiler

Published: July 2020

Abstract. Aerial emission sampling of four natural gas boiler stack plumes was conducted using an unmanned aerial system (UAS) equipped with a light-weight sensor/sampling system (the “Kolibri”) for measurement of nitrogen oxide (NO), and nitrogen dioxide (NO2), carbon dioxide (CO2), and carbon monoxide (CO). Flights (n = 22) ranged from 11 to 24 minutes duration at two different sites. The UAS was maneuvered into the plumes with the aid of real-time CO2 telemetry to the ground operators and, at one location, a second UAS equipped with an infrared/visible camera. Concentrations were collected and recorded at 1 Hz. The maximum CO2, CO, NO, and NO2 concentrations in the plume measured were 10,000 ppm, 7 ppm, 27 ppm, and 1.5 ppm, respectively. Comparison of the NOx emissions between the stack continuous emission monitoring systems and the UAS/Kolibri for three boiler sets showed an average of 5.6 % and 3.5 % relative percent difference for the run-weighted and carbon-weighted average emissions, respectively.
A statistical approach to fast nowcasting of lightning potential fields
Authors: North Joshua , Stanley Zofia , Kleiber William , Deierling Wiebke , Gilleland Eric , Steiner Matthias
Published: July 2020

Abstract. Thunderstorms and associated hazards like lightning can pose a serious threat to people outside and infrastructure.
Thus, very short-term prediction capabilities (called nowcasting) have been developed to capture this threat and aid in decision-making on when to bring people inside for safety reasons.
The atmospheric research and operational communities have been developing and using nowcasting methods for decades, but most methods do not rely on formal statistical approaches.
A novel and fast statistical approach to nowcasting of lightning threats is presented here that builds upon an integro-difference modeling framework.
Inspiration from the heat equation is used to define a redistribution kernel, and a simple linear advection scheme is shown to work well for the lightning prediction example.
The model takes only seconds to estimate and nowcast and is competitive with a more complex image deformation approach that is computationally infeasible for very short-term nowcasts.

Abstract. The surface ocean receives important amounts of organic carbon from atmospheric deposition. The degree of bioavailability of this source of organic carbon will determine its impact on the marine carbon cycle. In this study, the potential availability of dissolved organic carbon (DOC) leached from both desert dust and anthropogenic aerosols to marine heterotrophic bacteria was investigated. The experimental design was based on 16-days incubation, in the dark, of a marine bacterial inoculum into artificial seawater amended with water-soluble Saharan dust (D-treatment) and anthropogenic (A-treatment) aerosols, so that the initial DOC concentration leachate from aerosols is 36 µM C. Glucose-amended (G) and non-amended (control) treatments were run in parallel. Over the incubation period, an increase in bacterial abundance (BA) and bacterial production (BP) was observed first in the G-treatment, followed then by D and finally A treatments, with bacterial growth rates significantly higher in the G and D treatments than the A treatment. Following this growth, maxima of BP reached were similar in D (879 ± 64 ng C L−1 h−1; n = 3) and G (648 ± 156 ng C L−1 h−1; n = 3) treatments and were significantly higher than in A-treatment (124 ± 39 ng C L−1 h−1; n = 2). The DOC consumed over the incubation period was similar in A (9 ± 4 µM; n = 2) and D (9 ± 2 µM; n = 3) treatments and was significantly lower than that consumed in the G-treatment (22 ± 3 µM). Nevertheless, the bacterial growth efficiency (BGE) in the D treatment (14.2 ± 5.5 %; n = 3) compared well with the G treatment (7.6 ± 2 %; n = 3), suggesting that the metabolic use of the labile DOC fraction in both conditions was energetically equivalent. In contrast, the BGE in the A-treatment was lower (1.7 ± 0.1 %; n = 2), suggesting that the most part of used labile DOC was catabolized. The results obtained in this study highlight the potential of aerosol organic matter to sustain the metabolism of marine heterotrophs and stress the need to include this external source of organic carbon into biogeochemical models, for a better constraining of the carbon budget.

Abstract. In the current era of rapid climate change, accurate characterization of climate-relevant gas dynamics – namely production, consumption and net emissions – is required for all biomes, especially those ecosystems most susceptible to the impact of change. Marine environments include regions that act as net sources or sinks for a number of climate-active trace gases including methane (CH4) and nitrous oxide (N2O). The temporal and spatial distributions of CH4 and N2O are controlled by the interaction of complex biogeochemical and physical processes. To evaluate and quantify the importance of these mechanisms relevant to marine CH4 and N2O cycling requires a combination of traditional scientific disciplines including oceanography, microbiology, and numerical modeling. Fundamental to all of these efforts is ensuring that the datasets produced by independent scientists around the world are comparable and interoperable. Equally critical is transparent communication within the research community about the technical improvements required to increase our collective understanding of marine CH4 and N2O. An Ocean Carbon & Biogeochemistry (OCB) sponsored workshop was organized to enhance dialogue and collaborations pertaining to marine CH4 and N2O. Here, we summarize the outcomes from the workshop to describe the challenges and opportunities for near-future CH4 and N2O research in the marine environment.
A framework to evaluate IMEX schemes for atmospheric models
Authors: Guba Oksana , Taylor Mark A. , Bradley Andrew M. , Bosler Peter A. , Steyer Andrew
Published: July 2020

Abstract. We present a new evaluation framework for implicit and explicit (IMEX) Runge-Kutta timestepping schemes. The new framework uses a linearized nonhydrostatic system of normal modes. We utilize the framework to investigate stability of IMEX methods and their dispersion and dissipation for gravity, Rossby, and acoustic waves. We test the new framework on a variety of IMEX schemes and use it to develop and analyze a set of 2nd order low-storage IMEX Runge-Kutta methods with high CFL. We show that the new framework is more selective than the 2D acoustic system previously used in literature. Schemes that are stable for the 2D acoustic system are not stable for the system of normal modes.
Fault Network Reconstruction using Agglomerative Clustering: Applications to South Californian Seismicity
Authors: Kamer Yavor , Ouillon Guy , Sornette Didier
Published: July 2020

Abstract. In this paper we introduce a method for fault network reconstruction based on the 3D spatial distribution of seismicity. One of the major drawbacks of statistical earthquake models is their inability to account for the highly anisotropic distribution of seismicity. Fault reconstruction has been proposed as a pattern recognition method aiming to extract this structural information from seismicity catalogs. Current methods start from simple large scale models and gradually increase the complexity trying to explain the small scale features. In contrast the method introduced here uses a bottom-up approach, that relies on initial sampling of the small scale features and reduction of this complexity by optimal local merging of substructures. First, we describe the implementation of the method through illustrative synthetic examples. We then apply the method to the probabilistic absolute hypocenter catalog KaKiOS-16, which contains three decades of South Californian seismicity. To reduce data size and increase computation efficiency, the new approach builds upon the previously introduced catalog condensation method that exploits the heterogeneity of the hypocenter uncertainties. We validate the obtained fault network through a pseudo prospective spatial forecast test and discuss possible improvements for future studies. The performance of the presented methodology attests the importance of the non-linear techniques used to quantify location uncertainty information, which is a crucial input for the large scale application of the method. We envision that the results of this study can be used to construct improved models for the spatio-temporal evolution of seismicity.
Differences in damping of edgewise whirl modes operating an upwind turbine in a downwind configuration
Authors: Wanke Gesine , Bergami Leonardo , Verelst David Robert
Published: July 2020

Abstract. The qualitative changes in damping of the first edgewise modes when an upwind wind turbine is
converted into the respective downwind configuration are investigated. A model of a Suzlon S111
2.1 MW turbine is used to show that the interaction of tower torsion and the rotor modes
is the main reason for the change in edgewise damping. For the forward whirl mode, a maximum
decrease in edgewise damping of 39 % is observed and for the backward whirl mode, a maximum
increase of 18 % in edgewise damping is observed when the upwind configuration is changed into
the downwind configuration. The shaft length is shown to be influencing the interaction between
tower torsion and rotor modes as out-of-plane displacements can be increased or decreased with
increasing shaft length due to the phase difference between rotor and tower motion. Modifying the
tower torsional stiffness is seen to give the opportunity in the downwind configuration to account
for both a favorable placement of the edgewise frequency relative to the second yaw frequency and a favorable phasing in the mode shapes.
El Corán de ‘Uṯmān en al-Ándalus y el Magreb. Antología de las crónicas musulmanas. Análisis y lectura comparada
Authors: Bouayed Kamal A.
Published: July 2020

Las escasas fuentes antiguas acerca de la presencia de Muṣḥaf ‘Uṯmān en al-Ándalus y el Magreb, los debates acerca de su autenticidad y el verdadero papel que jugó este manuscrito en cada orilla del mediterráneo me llevaron a emprender una larga investigación sobre el manuscrito más famoso del Corán, aquel Libro que se heredaban en al-Ándalus y el Magreb Emires y Califas, ostentándolo como reliquia sagrada tanto en los actos religiosos como en las campañas militares buscando su bendición y su protección, y que tuvo en el periodo de seis siglos tanta influencia social, religiosa y geopolítica como pocas reliquias han tenido a lo largo de la historia de la humanidad. Tras consultar una amplia bibliografía y estudios al respecto, he observado una aparente falta de síntesis de las crónicas medievales así como unas verdaderas lagunas en el análisis de las cadenas de transmisión por lo que a través de una profunda investigación de las fuentes, a la vez empírica y exhaustiva, he querido probar con una lectura comparada de los textos de los cronistas medievales que mencionaron Muṣḥaf ‘Uṯmān que la elevación de esta reliquia al rango de mito y adoptado como objeto de veneración y de creencia religiosa en el seno de pueblos y dinastías de al-Ándalus y el Magreb mantuvo a lo largo de los siglos y a manos de numerosos soberanos su carácter sacro y su aspecto protector, aunque su uso se instrumentalizó como talismán y como símbolo de legitimización y de cohesión social.
Nuevas poéticas históricas en las bienales de arte. Arte y acción social
Authors: Capdevila Pol
Published: July 2020

Vivimos tiempos complejos y cargados de contradicciones. Este artículo analiza la manifiestación de esta complejidad en el arte de acción social tomando en consideración un elemento fundamental: el tiempo. Para ello, la primera parte del artículo presenta los principales modelos de temporalidad aplicados a nuestra sociedad: el primer modelo se refiere a la experiencia cotidiana del tiempo; el segundo, a la temporalidad histórica, y el tercero, a modelos sobre las tendencias generales de nuestra sociedad. Para organizar esta topografía, me he inspirado en el esquema de aporías temporales de Ricoeur en Tiempo y narración. La obra de Ricoeur argumenta que los diferentes modelos del tiempo no son compatibles entre sí, sino complementarios. La tesis del artículo consiste en trasladar este análisis al arte. Así, afirmaré que el arte contemporáneo manifiesta, sin cohesionarlas, las contradictorias visiones del tiempo y sus correspondientes tensiones sociales. Para desarrollar esta idea, analizaré la paradójica estructura temporal de formas artísticas como la apropiación, la performance y la participación. Estas formas aparecen en los dos proyectos artísticos que analizo al final como ejemplos representativos de la documenta 14 de Kassel. El molino de sangre y La sociedad de amigos de Halit son dos proyectos que, aunque de naturaleza diferente entre sí, tienen en común el poner de relieve conflictos sociales e históricos a partir de aporías temporales. Ambos tienen también como novedad buscar una salida pragmática a estas contradicciones.

The Need to Implement Modelling and Simulation as Part of the Curriculum in Basic Engineering Courses
Authors: Ghazy Mohammed , Ata Atef
Published: July 2020

In this paper a proposal for implementing modelling and simulation techniques into the curriculum of basic engineering courses is introduced. Justifications and case studies from some engineering courses are discussed. Examples from particle and rigid body motions in engineering mechanics course and other related courses are emphasized. In this proposal we introduce a method of simplification of basic concepts in applied engineering sciences. The concept of course project can be utilized to encourage students to apply their basic knowledge on modelling and simulation of some basic topics such as projectile and constrained motions. This proposal has the advantages of communicating concepts in science through the daily use of communication technology among students and instructors. Simulation can attract other students, who find difficulty understanding engineering problems, to the engineering profession. In addition, the new proposal can be applied with no additional cost on the institution, no extra credit hours for students, and a minimum additional load on the instructor.
Use of Ketamine in Sphynx Cats
Authors: Adami Chiara , Monticelli Paolo
Published: July 2020

Since the early 1990s, a number of deaths of Sphynx cats have been anecdotally reported following ketamine-based anesthesia. These episodes have raised concerns, between breeders and owners of that peculiar cat breed, that their cats may not be looked after with the care they deserve and that veterinarians might not be adequately informed about breed-specific drug toxicities. This article reviews some aspects of the clinical pharmacology of ketamine, which, in these authors’ opinion, analyzed together with the breed-specific peculiarities of Sphynx cats, may provide some explanations for the lethal outcomes reported over the last decades.
MRI Features of Presumed Primary Extranodal Lymphoma of the Bulbospongiosus Muscle Causing Stranguria
Authors: Humphreys William , Finotello Riccardo , Schiborra Frederike
Published: July 2020

Hematopoietic neoplasia is common in dogs, with canine non-Hodgkin lymphomas representing more than 80% of all hematopoietic cancer. However, extranodal infiltration of the skeletal muscle by non-Hodgkin lymphoma is rare in humans and dogs. A 9 yr old neutered male English mastiff presented with a 3 wk history of recurrent stranguria, pelvic limb ataxia, and mild proprioceptive deficits bilaterally, worse in the right pelvic limb. MRI showed an expansile ill-defined lesion within the bulbospongiosus muscle. The lesion had intermediate signal intensity to muscle and fat on T2-weighted imaging and was isointense to unaffected muscle on precontrast T1-weighted imaging. Contrast enhancement was heterogeneous and there was digitate signal alteration within adjacent perilesional fat. Ultrasound examination confirmed a hypoechoic lesion infiltrating the muscle. Cytological examination yielded a diagnosis of high-grade lymphoma. This report provides the first description of MRI findings associated with cytologically confirmed lymphoma of the skeletal muscle in the dog. Although nonspecific, the imaging features strongly correlate with those in the medical literature and lymphoma should be considered a pertinent differential in cases presenting with similar imaging findings.

Published: July 2020

O presente relato compartilha a experiência de ensino de figuras de linguagem à luz dos Estudos do Letramento e das orientações da Base Nacional Comum Curricular - BNCC, realizada em turmas de oitavo ano dos anos finais do Ensino Fundamental de duas escolas públicas municipais de Fortaleza. Como aporte teórico, utilizamos os Estudos do Letramento (STREET, 2014; KLEIMAN, 1995; 1997; 2010; 2012; SOARES, 1998; 2004; 2008), que entendem que a escrita é uma prática social que se realiza a partir das pluralidades culturais de cada esfera de discurso. Partimos, ainda, das reflexões empreendidas por Antunes (2003) e Travaglia (2003), bem como dos norteamentos da BNCC (2018) acerca de um ensino de análise linguística/semiótica que se engendra a partir de uma concepção sociointeracionista da língua. Embasados nessa conjuntura teórica, pudemos perceber que a análise das figuras de linguagem em textos musicais possibilita a construção de criticidade leitora nos estudantes, de modo que estes, para além de identificar essas construções, também foram capazes de perceber os diferentes valores, discursos e ideologias que perpassam os textos.
INFLUENCIANDO LEITORES, CONTRA TERRA PLANA: O ETHOS NA REVISTA SUPERINTERESSANTE ONLINE
Authors: Paré Glück Eduardo , Zandonai Marcos Filipe
Published: July 2020

Este artigo toma como objetivo principal investigar como se manifesta o ethos da instância de produção da informação em um artigo de opinião no escopo da divulgação científica midiática. Buscou-se, mais especificamente, verificar as estratégias que permitem ao locutor identificar-se com um ethos atrativo de ciência e favorável à sua racionalidade, segundo o contrato de comunicação de midiatização da ciência (CHARAUDEAU, 2016). Para acesso ao status do locutor, valemo-nos dos Modos de Organização Enunciativo e Argumentativo e do pathos (CHARAUDEAU, 2009b; 2010), nas formas textuais que elas assumem para corresponder ao gênero. Em uma abordagem qualitativa, os resultados mostram, por exemplo, duas tópicas globais no plano de texto, a da Repulsa e a da Antipatia, que, combinadas a outros recursos de captação, constroem um ethos de Identificação. O outro ethos identificado é o de Credibilidade. Juntos, os dois instrumentalizam a posição de aliança com o público identificado da revista e de oposição ao antifiador.

The purpose of the study was to justify and check experimentally the efficiency in the application of distance learning technologies to ensure future teachers’ readiness to pedagogical work in the process of general professional training. The quasi-experimental research was conducted while delivering the disciplines of “Pedagogics” and “Psychology” included in the cycle of general professional training. The levels of motivational, activity-oriented, and cognitive components of future teachers’ readiness to pedagogical work were measured using the determination methodology for the factors of the profession’s attractiveness developed by Yadov, the questionnaire entitled “The identifier of problematic dominant level in the process of addressing pedagogical tasks”, and the results of the final tests. To analyse the results obtained and to study objectively dynamics of changes in activity orientated, cognitive, and motivational elements, the research has used methods of mathematical data processing and a STATISTICA software for statistical analysis. The research found the efficiency of distance courses implementation with active teaching methods on the development of all components of future teachers’ readiness to pedagogical work. The author concluded that in the context of the general professional training of teachers and adaptation to the peculiarities of distance learning, the most efficient methods are the following: case-study, a problem-oriented lecture, a method of projects, portfolio, and discussion. In the view of the author, distance educational technologies, means of virtual visualisation and interactive content help broaden the didactical potential of active methods of pedagogical interaction and diversify delivery of the training material.
The Changing of the Guard in Academia and Academic Research Leadership—Employing Natural Language Processing
Authors: Eckhaus Eyal , Davidovitch Nitza
Published: July 2020

This pioneering study examines the meaning of academic leadership in terms of the changing of the guard in academia. Research findings on seniority and experience and their association with leadership show that these have a considerable impact on management skills and on the ability of those with experience and seniority to influence the young leadership. This is particularly essential in academia where research is the most meaningful and effective value that serves as a measure of faculty members. Management skills are not perceived as a coherent part of faculty members’ work.

Structural Equation Modeling confirmed the developed model. Findings show that indeed, from the perspective of faculty at the academic institution, senior experienced faculty members undoubtedly contribute to the academic institution first of all in research, but also otherwise. Senior and experienced faculty members contribute by encouraging, directing, and guiding young faculty members on how to contribute to the institution, particularly through the activity which is expected of them as academic faculty – i.e., research. This urging and direction is one of the most well-known qualities in the context of academic leadership – the ability to help people develop, advance, and to outline a high-quality academic research tradition. The meaning of the findings is that senior faculty has a contribution beyond their direct output in the form of scientific publications, as a research engine and spotlight for the young faculty. Notably, no difference was found in faculty’s perception of this contribution of senior faculty members by gender or age.
Intensive feeding of humpback whales (Megaptera novaeangliae) in the breeding ground of Banderas Bay, Mexico

Published: July 2020

Banderas Bay, located in the Mexican Pacific, is a breeding/calving ground for the North Pacific stock of humpback whales (Megaptera novaeangliae) during the winter.  While sporadic registers of humpback whales feeding on their mating grounds exist, this is the first occasion where feeding activity was observed intensively and extensively on a breeding ground.  Between 19 December 2011 and 6 March 2012, 26 such occurrences were registered in Banderas Bay, along the mainland pacific coast.  On five occasions, groups of 20 or more individuals were recorded feeding. They were feeding over and under the surface using lunging and gulping techniques.  On several occasions humpbacks were observed feeding alongside Bryde´s whales (Balaenoptera edeni), Pantropical spotted dolphins (Stenella attenuata) and Bottlenose dolphins (Tursiops truncatus).  Two different samples of fish at two different feeding sites were taken and the fish identifications showed these were Pacific anchovies (Cetengraulis mysticetus).  Among the 26 sightings, nine different species of birds were registered feeding in the same area as the humpback whales.  The number of whales feeding over an extended period of time in their breeding ground could be an indicator that there was not enough food in their feeding grounds, but the possibility that they might just be taking advantage of good food availability is also possible.

Authors: Fijałkowska Marta , Antoszewski Bogusław
Published: July 2020

Background. Neurofibromatosis type 1 (NF-1) is one of the most common autosomal dominant disorders. Multiple benign dermal neurofibromas, cafe´ au lait spots, axillary and inguinal freckling are the hallmarks of NF1.
Aim. The aim of this paper is to verify if surgical treatment performed in patients with NF-1 is satisfactory for them and to describe demographic factors characteristic to patients with Recklinghausen disease.
Methods. A special questionnaire was prepared for the study, which contained 45 questions. Seventeen patients with neurofibromatosis type 1 agreed to fill in the questionnaire aged from 22 to 61 years.
Results. Surgical treatment in patients was started between 6 and 45 years of age. All patients declare their will to continue surgical treatment. After treatment patients think that they are more comfortable, more self-confident and sociable. The first symptoms of neurofibromatosis were seen in about 13 years of life in most patients. In the group of women who gave a birth all of them noticed progression of the disease during pregnancy.
Conclusions. Performed surgical treatment raises life comfort and increase self-confidence in patients with neurofibromatosis type 1. Due to visibility of neurofibromas it is worth to refer patients to Department of Plastic Surgery. Doctors dealing with patient with NF-1shoud inform them about its inheritance basis and that puberty and pregnancy intensify the process of skin neurofibroma development.

Assistimos à proliferação de sistemas cujo poder ultrapassa a experiência humana. Mas, pode-se confiar que eles não fazem nenhum julgamento de valor? Ou que seus criadores não embutem prejulgamentos sutis e/ou imperceptíveis aos próprios? Partindo deste contexto, participantes de um encontro que reúne entusiastas em novas tecnologias (a Campus Party) e alunos de um curso de Ciência e Tecnologia de uma universidade foram questionados sobre suas percepções a respeito da confiança em algoritmos, transcendência e privacidade. Este artigo descreve e analisa o resultado desta pesquisa na tentativa de compreender os receios e/ou engajamentos dos seus participantes, nesta que promete ser a mais revolucionária das eras.
