LA ESCUELA VISTA POR MUJERES DE TRES GENERACIONES DE MÉXICO Y COLOMBIA
Authors: Ibarra Uribe Luz Marina , Piña Osorio Juan Manuel
Published: June 2020

El artículo presenta hallazgos de una investigación sobre la percepción que de la escuela, su función y quehacer tienen triadas familiares de hombres y mujeres de dos países latinoamericanos. Para este trabajo se seleccionaron dos triadas de mujeres (abuelas, madres y nietas), una colombiana y otra mexicana, con el objetivo de recuperar, a través de narrativas, lo que representó y representa para ellas y sus familias su paso por la escuela; así como identificar las continuidades, cambios y rupturas experimentadas por dichas generaciones. Uno de los hallazgos importantes es la relevancia que le confieren al hecho de haber estudiado en escuelas privadas de corte confesional católico, por la oportunidad de aprender y formarse dentro de valores, hábitos y disciplinas que resultan tanto o más importantes en su formación que los propios conocimientos disciplinares. Se encontraron en los relatos sentimientos positivos respecto a los logros educativos personales y de la familia. Asomaron en los testimonios emociones como orgullo, satisfacción y alegría por asistir a la escuela, y en el caso de las mujeres que no concluyeron sus estudios, arrepentimiento y frustración.

Authors: Guérin Jérôme , Yurén Camarena Teresa
Published: June 2020

El objetivo de la investigación reportada consistió en formular hipótesis sobre los factores clave de una educación terapéutica eficaz destinada a personas con enfermedad crónica. Se hizo el análisis del curso de vida de una diabética que participó en una red de salud orientada a promover la transformación de los hábitos de vida de los enfermos. La metodología se orientó a que la enferma determinara y reconstruyera los periodos de actividad en torno a su enfermedad. Los resultados presentan los aprendizajes logrados y los cambios ocurridos en un lapso de dos años, y ponen en evidencia la modificación progresiva de la relación con su enfermedad, la transformación de los hábitos de vida y de la confianza en sí, y el papel de la relación intersubjetiva. Un meta-análisis efectuado sobre esos resultados permitió formular como hipótesis que la educación terapéutica requiere de un proceso formativo de carácter dialéctico y de una mediación cuyo componente ético es el reconocimiento de la alteridad.

Authors: Izarra Vielma Douglas A.
Published: June 2020

Se presentan los resultados de una investigación orientada a identificar cómo se integra el comportamiento ético en la identidad profesional docente. En esta oportunidad tal cuestión se trató a partir de la Escala de Actitudes sobre Ética Profesional (Hirsch, 2005) la cual fue aplicada a un grupo de docentes y estudiantes de posgrado de tres instituciones de educación universitaria en Venezuela. Los resultados demuestran una actitud favorable hacia las competencias éticas, cognitivas y afectivo-emocionales. Se evidencia una valoración muy dispar en relación con las competencias técnicas (habilidades didácticas) y resulta particularmente preocupante la valoración que se hace de las relaciones con los otros docentes (competencias sociales). Se concluye destacando la necesidad de promover el desarrollo profesional de los docentes lo cual permitirá el fortalecimiento de su identidad profesional y un desempeño enmarcado en la ética profesional.
LA PRUEBA DE COMPETENCIA MATEMÁTICA DE 6.º DE PRIMARIA COMO PRUEBA DE DIAGNÓSTICO EN FUTUROS MAESTROS
Authors: Nortes Checa Andrés , Martínez-Artero Rosa Nortes
Published: June 2020

Las pruebas de diagnóstico son necesarias para determinar la competencia matemática de los estudiantes que acceden a los grados de maestro. A tal fin se toma una muestra de alumnos del GMP del curso 17/18 a los que se les pasa la prueba de competencia matemática de 6.º de Primaria. De los 32 ítems de la prueba seis no se superan, la media de la muestra de 233 participantes es de 6,43 sobre diez, obteniendo por bloques de contenidos: incertidumbre (6,90), números (6,81), medida (6,07) y geometría (5,74), siendo uno de cada cinco estudiantes quien no llega a alcanzar el 5. Esta prueba de haber sido oficial, establecida por ley como está en Cataluña, con la Prueba de Aptitud Personal, habría significado que un 20% de estudiantes habrían sido declarado No Aptos para realizar los estudios que acceden al Grado de Maestro.
The Concept of Servant Leadership in Business Management
Authors: Rumbidzai Muzira Dumisani , Muzira Robert
Published: June 2020

This concept paper is a response to the calls for more research on servant leadership. It was propelled by the fact that many studies on leadership have focused on transformational leadership and team leadership in a midst of increasing interest on servant leadership. Although the servant leadership concept has been criticized for lack of empirical evidence, it is a viable option for this age which has been characterized by unethical dealings in the business world. In this situation, a leadership concept that appeals to human morals might therefore be the solution. The paper is based on literature search that seeks to explain the concept of servant leadership in business management by identifying its attributes, its antecedences and its outcomes. It also sought to make a distinction between leadership and management, authority and power in the context of servant leadership. A conceptual framework on servant leadership is then proposed. Practical examples on servant leadership as well as its criticisms are discussed. The conceptual framework will guide the organizations that seek to try out the servant leadership concept in their operations. It will also help individuals with the desire to become servant leaders on what is expected of them. Adoption of the servant leadership concept in organizations will also reduce the occurrences of business failures and financial scandals.

This research is aimed to help students develop their mathematical concept, as well as emphasizing the appropriate use of information technology among Year Three students. The current mathematics curriculum in Year Three primary school in Malaysia was introduced in 2018. This quantitative study used a quasi-experimental method. Thus, this study examines the differences in performance between a controlled group and experimental group from a school in Malaysia. Paired samples test results have proven that the experimental group performed better than the controlled group. It was also found that fun and interactive games can increase students’ understanding and interest towards mathematics. Interactive games can contribute least time to master some mathematical concepts in a fun way. Therefore, the fun and interactive game is a superior instrument that can be utilized by primary students in learning mathematics in order to encourage learning and innovation skills in the 21st century.
Legal protection of cross-border use of intellectual property
Authors: Kiryushina Irina , Serebryakov Andrey
Published: June 2020

The paper analyzes the issues of legal regulation of cross-border use of intellectual property on the example of the Eurasian Economic Union. Among the key problems of cross-border use of intellectual property within the Eurasian Economic Union (EEU) is the need to create a unified system of registration of trademarks and service marks and elimination of double registration of trademarks, establishment of common approaches to the problem of admissibility of “parallel imports” within the EEU, and the creation of an effective patent system. The authors conclude that the development of legal regulation of the use of intellectual property in cross-border relations will follow the path of adoption of normative acts within the framework of regional unions of states, taking into account the specifics of their economic and social development, as well as the way of improvement of national legislation, taking into account the position of states on this issue.

Neste artigo, analiso como se deu a implantação do sistema Bata – conjunto de métodos de produção e de técnicas de gestão – no Brasil e no Chile, entre as décadas de 1940 e 1970, tendo como principal objetivo interpretar as características do projeto de controle social que buscava exercer um domínio praticamente total sobre os trabalhadores, indo além dos espaços e dos tempos de trabalho, ao adentrar as esferas domésticas e os períodos de ócio.
Permanent Complete Heart Block After Kaala Pathar (Paraphenylene Diamine) Poisoning: A Case Report
Authors: Saleemi Sohail , Akhtar Ammar
Published: June 2020

Kaala Patthar, containing paraphenylene diamine (PPD) chemically, is used as a hair dye in South Punjab. Recent trends have shown its increasing use as a poison. The common manifestations of Kala Patthar poisoning include upper airway edema, rhabdomyolysis, and acute renal shutdown. However, cardiac toxicity is a rare complication and the conduction abnormalities are seldom reported. We are going to report a case of permanent complete heart block after Kaala Patthar poisoning where the patient needed permanent pacemaker to save his life.
Historical droughts in the Qing dynasty (1644–1911) of China
Authors: Lin Kuan-Hui Elaine , Wang Pao K. , Pai Pi-Ling , Lin Yu-Shiuan , Wang Chih-Wei
Published: June 2020

Abstract. This study presents a new epistemological analysis of drought
chronology through a well-defined methodology for reconstructing past
drought series, as well as series of other associated ecological and societal
impact variables. Instead of building a grading system based on mixed
criteria, this method facilitates transparency in the reconstruction process and
enables the statistical examination of all variables when building series. The
data for the present study are derived mainly from the REACHES (Reconstructed East Asian Climate Historical Encoded Series) database;
however, other archival documentary and index data from independent sources
are also applied to understand drought narratives and to cross-check and
validate the analysis derived from REACHES. From the time series analysis,
six severe drought periods are identified in the Qing dynasty, and then a
spatial analysis is performed to demonstrate the spatial distribution of drought
and other variables in the six periods, as well as a social network analysis to
reveal connections between drought and other ecological and societal
variables. Research results clearly illustrate the role of human
intervention in influencing the impacts of drought and their societal consequences.
Particularly, the correlation between drought and socioeconomic turmoil is not
strong; crop failure and famine are important intermediate factors,
while ecological factors such as locust and disaster relief measures are
all imperative to intervene between crop production and famine. Implications
of the study on drought impact are provided, as well as the significance of drought on
historical climate reconstruction studies.
Computing water flow through complex landscapes – Part 2: Finding hierarchies in depressions and morphological segmentations
Authors: Barnes Richard , Callaghan Kerry L. , Wickert Andrew D.
Published: June 2020

Abstract. Depressions – inwardly draining regions of digital elevation models – present difficulties for terrain analysis and hydrological modeling. Analogous “depressions” also arise in image processing and morphological segmentation, where they may represent noise, features of interest, or both. Here we provide a new data structure – the depression hierarchy – that captures the full topologic and topographic complexity of depressions in a region. We treat depressions as networks in a way that is analogous to surface-water flow paths, in which individual sub-depressions merge together to form meta-depressions in a process that continues until they begin to drain externally. This hierarchy can be used to selectively fill or breach depressions or to accelerate dynamic models of hydrological flow. Complete, well-commented, open-source code and correctness tests are available on GitHub and Zenodo.
Enhancing the operational value of snowpack models with visualization design principles
Authors: Horton Simon , Nowak Stan , Haegeli Pascal
Published: June 2020

Abstract. Forecasting snow avalanches requires a reliable stream of field observations, which are often difficult and expensive to collect. Despite the increasing capability of simulating snowpack conditions with physical models, models have seen limited adoption by avalanche forecasters. Feedback from forecasters suggests that model data are presented in ways that are difficult to interpret and irrelevant to operational needs. We apply a visualization design framework to enhance the value of snowpack models to avalanche forecasters. An established risk-based avalanche forecasting workflow is used to define the ways forecasters solve problems with snowpack data. We suggest that model data be visualized in ways that directly support common forecasting tasks such as identifying snowpack features related to avalanche problems and locating avalanche problems in terrain at relevant spatial scales. Examples of visualizations that support these tasks and follow established perceptual and cognitive principles from the field of information visualization are presented. Interactive designs play a critical role in understanding these complex datasets and are well
suited for forecasting workflows. Although extensive user testing is still needed to evaluate the effectiveness of these designs, visualization design principles open the door to more relevant and interpretable applications of snowpack model for avalanche forecasters. This work sets the stage for implementing snowpack models into visualization tools where forecasters can test their operational value and learn their capabilities and deficiencies.
Differences in High School CTE Coursetaking by Gender and Race/Ethnicity
Authors: Leu Katherine B. , Arbeit Caren A.
Published: June 2020

The purpose of this study was to examine patterns in high school career and technical education (CTE) coursetaking by gender and race/ethnicity across two cohorts of students over time. Using high school transcript data from the Education Longitudinal Study of 2002 (ELS:2002) and the
High School Longitudinal Study of 2009 (HSLS:09), we examined participation in CTE both overall and disaggregated by field of study. While there were some differences by gender and race/ethnicity in overall CTE participation, disaggregating by field of study revealed wide variation in participation
rates in each field. We found large and sustained differences in participation across CTE fields of study by gender as well as pronounced patterns by race/ethnicity, with some changes over time. Overall, these gender and racial/ethnic differences were notable because they persisted even after
controlling for other potential explanatory factors.
Exploring Employer Perspectives of Community College Career and Technical Programs
Authors: Gauthier Thomas
Published: June 2020

This qualitative study explores the efficacy of community college career and technical education programs through employer perspectives. Participants for this study were cultivated from a variety of industries and disciplines. Predominant themes that emerged from this study include
education, authentic experience, the value of career and technical education, workplace social structure, apprenticeship, and aptitude. Employers appear to be ambivalent regarding their perspective of community college career and technical programs. Employers are looking for employees who
can be integrated into the workplace social structure easily, and they articulate competencies generally gained after completing a two-year degree program. Participants reported that new employees lack employability skills, a higher order of thinking, metacognition, mature nature of competency,
social mobility, motivation, and positive self-efficacy. Therefore, this study concludes that the hiring of community college career and technical graduates is contingent on the applicants' job-related skills and social competency.
What type of subjectivity lies behind French causal connectives? A corpus-based comparative investigation of car and parce que
Authors: Blochowiak Joanna , Grisot Cristina , Degand Liesbeth
Published: June 2020

In French, the difference between the causal connectives parce que and car is traditionally related to the prototypical causal relations they are meant to convey. The main claim is that car conveys more subjective relations and is also used in higher register language, whereas parce que is equally well-suited to both types of relations. In line with recent studies, this contribution questions the clear-cut distinction between the two connectives on the basis of a comparative corpus investigation with annotation tasks (journalistic and text messaging registers). Our results do not corroborate the traditional hypotheses that car is used to express more subjective relations and it is restricted to higher register language. On the contrary, we find that car has a strong tendency to be perceived by addressees as providing the information in a more objective way. Our empirical investigation has allowed us to put forth a modified notion of subjectivity which is associated with car and parce que: we distinguish between the more classic approach – the type of subjectivity related to causal relations, and a novel approach – the evaluative type of subjectivity related to the expressive use of language. We rely on the relevance-theoretic framework to spell out our theoretical proposal.

Authors: Marzouk Tyseer , Nabil Hanan
Published: June 2020

Objective: This study aimed to evaluate effectiveness of pelvic floor muscles training on females’ sexual function throughout pregnancy and postpartum.Methods: A quasi experimental research design was applied at the antenatal clinic of Mansoura University hospital, Egypt. A purposive sample of 72 nulliparous singleton pregnant client free from any connotation affect sexual practice was studied. The subjects were allocated into two groups; control group received conventional antenatal and postnatal care, while the intervention group received the same care besides performing pelvic floor muscle exercise at 20 weeks pregnancy until 10-12 weeks postpartum. Female sexual function, sexual quality of life, and strength of the pelvic floor muscle contraction were evaluated at baseline, at 28-30 weeks gestation, and at 10-12 weeks postpartum, by using the female sexual function index scale, sexual quality of life-female, and the Oxford grading scale.Results: The total female sexual quality of life index scores in the intervention group were higher than those of the control group at the pregnancy and postpartum follow ups (22.3 ± 6.9 vs. 15.9 ± 6.8 & 26.0 ± 6.7 vs. 13.5 ± 6.3 respectively; p < .001). The sexual quality of life-female scores were significantly higher in the intervention group than in the control group at the pregnancy follow up evaluation (54.2 ± 15.9 vs. 36.9 ± 9.7 respectively, p < .001) and at the postpartum follow up evaluation (59.8 ± 13.5 vs. 30.3 ± 7.0 respectively, p < .001). The pelvic floor muscles strength was significantly better in the intervention group than in the control group at the pregnancy follow up evaluation and at the postpartum follow up evaluation.Conclusions: Pelvic floor muscle training during early gestation weeks was an effective tool for improvement of the female sexual function, sexual quality of life-female, and pelvic floor muscles strength during pregnancy and postpartum. Thus, it should be encouraged for pregnant mothers at early weeks and continued till postpartum.

Authors: Stefkova Gabriela , Zamboriva Maria
Published: June 2020

AbstractObjective: Effective practice is increasingly seen as a critical dimension of the professional development of healthcare professionals. Reducing the number of punctures when placing an intravenous (I.V.) cannula reduces pain and further suffering for the patient. At the same time, the proper technique of I.V. cannulas save time for healthcare providers. Background: The method of securing venous access by intravenous cannula is part of the teaching of medical and nursing study programs. Critical thinking is the basic skill necessary to assess any information, explain the causes and the ability to solve problems. University education develops this skill through strategic teaching of simulation methods. Methods: In connection with new information of the method of I.V. cannulas by “magic movement”, we decided to use the Core model for critical reflection designed by Cottrell (2010), to evaluate new techniques in preclinical education of students from general medicine and nursing on I.V. cannulation in simulation laboratories. Results: The results have shown that student performance levels will be increased by applying critical thinking and simulation as an option for integrated pre-clinical training for future healthcare professionals. Conclusion: Innovative method of introducing peripheral I.V. cannula provides a framework to guide curriculum development and teaching strategies as well as to support the advance of cognitive and empirical skills of healthcare professionals. A new technique for applying “magic movement” of I.V. cannula we innovate the curriculum of basic nursing practices while contributing to the development of evidence-based practice.Key words: Intravenous catheter, Innovative method “magic movement”, Critical thinking, Simulation laboratories.
Maize hybrids contrasting for drought tolerance differ during the vegetative stage

Published: June 2020

Maize hybrids contrasting for drought tolerance differ during the vegetative stage. Drought is the main constraint on maize production in developing nations. Differences during development between genetic materials of maize grown under water restriction suggest that the plant can be improved with a view to its adaptation. In maize, sensitivity to water stress can occur at any stage of its phenological development. However, few studies report its effects on the vegetative phase of the cycle. On this basis, this study was conducted to examine how shoot and root-system indices are expressed in cultivation under water deficit as well as determine which indicators best explain the difference between hybrids in the evaluated water regimes. Commercial seeds of hybrids BR1055 and DKB-390 (drought-tolerant) and BRS1010 (drought-sensitive) were germinated in PVC tubes (1.0 m × 0.1 m) in a randomized complete block design, in a 3 × 2 factorial arrangement. The experiment was developed in a greenhouse where two water regimes were tested: no water stress and with water stress from the VE stage. The soil consisted of quartz sand mixed with a commercial fertilizer. Stem and root traits were evaluated up to the V5 growth stage. Relative chlorophyll content, leaf temperature, stem length, phenology, shoot dry biomass, root length, root dry biomass, root surface area, root volume and D95 were responsive to water deficit. The parameters that allowed the distinction between the hybrids in water the regimes were relative chlorophyll content, leaf temperature, phenology and average root diameter.

Published: June 2020

The sustainable use of soil requires a broad knowledge of its genesis, morphology, properties, and distribution in the landscape. Thus, the objective of this study was to characterize the pedogenetic attributes of representative soils from the cerrado-caatinga transition of the Gurguéia river basin to indicate their agricultural potential and limitations for the implementation of agroforestry systems. National and international soil classification systems were used to define the soil classes. The limiting factors and agricultural potential were characterized following the evaluation system of the agricultural potential of Brazilian land. In general, profiles 1, 3, 5, and 6 had a low nutrient budget and a sandy to loam texture. Profiles 2, 4, and 7 showed high clay content and nutrient budget. The soil profiles were classified as Ustic Quartzipsamments, Udic Haplusterts, Xanthic Haplustox, Arenic Kanhaplustults, Typic Haplustox, and Aridic Dystrustept based on their pedogenetic characteristics. Udic Haplusterts and Arenic Kanhaplustults soils display restrictions regarding the planting of forests owing to oxygen and soil depth limitations. The other soil classes had adequate physical properties for the implementation of agricultural systems and pastures, including good drainage and medium texture; however, they had low natural fertility, and thus require technologies for soil acidity correction and fertilization. Ustic Quartzipsamments and Ustic soils require the implementation of conservation systems, such as agroforestry, to avoid degradation.

Published: June 2020

The present study investigated the male effect on the estrus behaviors, estradiol and progesterone release in prepubertal Saanen goats. Twenty-nine female Saanen goats at 135 ± 10 days old with body weight of 22.8 ± 3.3 Kg were randomly assigned to three treatments: exposure to sexually active male (male treatment), exposure to androgenized females (androgenized female treatment), and prepubertal goats isolated from active male and androgenized females (control treatment). Sexual behaviors associated with estrus were recorded daily, and blood samples were taken weekly to determine estradiol and progesterone concentrations over 24 weeks. The experimental goats subjected to male or androgenized female had significantly higher frequency of estrus (mount acceptance) (P ? 0,02), progesterone (P ? 0,01), and estradiol (P ? 0,01) release than the control goats. Furthermore, goats exposed to a male showed estrus behavior two weeks earlier and maintained this estrus behavior for three weeks more than goats of both female and control treatments. Estrus was observed in 70 % of goats in male and female treatments during the breeding season versus 44 % of the control goats. Finally, significantly more goats subjected to male treatment (60 % of goats) showed progesterone concentrations higher than 1 ng mL-1 (which indicates the presence of a functional corpus luteum) compared to the female and control treatment (40 and 22 % of goats, respectively). These results shows that male treatment significantly increased the number of females showing estrus behavior, estradiol and progesterone release, and the number of animals with a functional corpus luteum, anticipating puberty for experimental goats, suggesting that the male effect could be used to anticipate the onset of puberty in goats.

The aim of this study was to evaluate the dynamics of the scrotal temperature, sperm quality and testicular blood flow by using infrared thermography and Doppler ultrasonography in bulls submitted to scrotal insulation. Braford bulls (n = 8) at 18 months of age, were assigned into the following groups: insulated for 72 h (G 72; n = 2), 96 h (G 96, n = 2), 120 h (G 120, n = 2), and control animals (CON; n = 2) that remained without insulation. Infrared thermography and Doppler ultrasonography parameters were measured at four different time points: immediately after the scrotal insulation (M0), within 10 min (M10), 30 min (M30) and 60 min (M60) after scrotal insulation. The sperm quality was evaluated weekly (S1/S12). The data were analyzed by ANOVA, t-test (paired) and Pearson's correlation with a significance level of 5%. None of the observed variables were different between the insulated groups (P > 0.05). Insulated animals showed higher scrotal temperature in M0 compared to that in the M10, M30 and M60 periods (P < 0.05). There was no difference in the pulsatility and resistive indexes after scrotal insulation. However, blood flow velocity was higher in M10 compared to that in the M0, M30 and M60 periods (P < 0.05). The sperm quality was higher (P < 0.05) in all twelve collections from the control group compared with the insulated groups. Scrotal insulation resulted in changes in the sperm quality, scrotal temperature and testicular blood flow velocity.

Published: June 2020

Bovine brucellosis, a zoonotic disease endemic to Brazil, is a serious public health problem. It is a notifiable disease that, like tuberculosis, is regulated through a national control and eradication program. The epidemiological status of bovine brucellosis must be characterized in order to direct measures aimed at controlling the disease. This study focused on analyzing the spatial and temporal distribution of bovine brucellosis in Brazil. An ecological and time series study was conducted based on secondary data reported by the National Animal Health Information System for cases of bovine brucellosis diagnosed in Brazil (2014 - 2018). The gross and average incidence rate of brucellosis was estimated per state. Joinpoint regression was applied to calculate the annual percentage change (APC) in incidence and to identify states with significant trend changes. Spatial analysis of animals with brucellosis was performed using Kernel density estimation. A total of 19,631 animals with bovine brucellosis were confirmed, and the average incidence rate varied from 0.03 to 33.93/100,000 cattle in Brazil. The highest density of positive animals was found in the states of Santa Catarina and Paraná, which can be considered areas of greater transmission of Brucella abortus. Reductions in gross incidence rates were observed in Paraná (APC: -13.2; 95% confidence interval [CI]: -20.3 – -5.4; p=0.01), Rondônia (APC: -44.7; 95%CI: -62.0 - -19.4; p=0.01), Mato Grosso do Sul (APC: -59.0; 95%CI: -77.7 - -24.5; p=0.01), Acre (APC: -40.0; 95%CI: -50.0 - -28.0; p=0.00), and Ceará (APC: -37.9; 95%CI: -50.9 - -21.4; p=0.00). The incidence rate significantly increased in Tocantins (APC: 122.1; 95%CI: 4.5 - 372.2; p=0.04). The findings of this study will be helpful in guiding surveillance and prevention measures aimed at reducing the incidence of bovine brucellosis in Brazil.

The Brazilian livestock activity is undergoing constant evolution, and aiming at its maximum efficiency, it is necessary to have available to the animals food in quantity and quality all the year. To this end, the cultivation of winter forage is carried out. The present study aimed to evaluate the productive and qualitative agronomic traits of ryegrass forage. The experiment was a randomized block design in a 3 x 2 factorial arrangement consisting of six treatments, three plant stands (525, 1050 and 2095 plants m-2) associated with two successive cutting times (vegetative and full vegetative), and four repetitions. There was no interaction between population stand and cutting times for the variables studied. The stand of 525 plants m-2 had a higher participation of green leaves (50.52 %), higher digestibility of the whole plant dry matter (84.81 %) compared to the stands of 1.050 and 2.095 plants m-2, and dry biomass production per unit area equivalent to the others (6087, 7243 and 6989 kg ha-1, respectively). The first harvest season presented higher participation of green leaves and better leaf/stem ratio, 58.62 % and 3.41 % respectively, as well as higher digestibility of green leaves (77.26 %) and stem (80.82 %).

This study aimed to propose a model called Two-compartment Logistic-von Bertalanffy (LVB) and to identify among the proposed and Two-compartment Logistic (TL) models the one that has the best goodness of fit to the kinetic curve of cumulative gas production (CGP) of sunflower and corn silages alone and combined using the in vitro semi-automated gas production technique. A random block split-plot experimental design was employed in which the inoculums were the blocks, the incubation times were the split-plots, and the experimental diets were: CS - corn silage, SS - sunflower silage (as single roughage), and their mixtures, i.e., 340SS (660 g kg-1 corn silage and 340 g kg-1 sunflower silage) and 660SS (340 g kg-1 corn silage and 660 g kg-1 sunflower silage). The parameters were estimated by the least squares method using the iterative Gauss-Newton process in the software R version 3.4.1. The criteria adopted were: adjusted coefficient of determination (R2adj.), residual mean squares (RMS), mean absolute deviation (MAD), Akaike information criterion (AIC), Bayesian information criterion (BIC), and relative efficiency (RE). The TL model had higher R2adj. values compared to LVB, however, such difference may be considered negligible. The LVB model had RE above one, which indicates it is superior to the TL model, in addition to the lowest RMS, MAD, AIC, and BIC values, The Two-compartment Logistic-von Bertalanffy model had the best fit to describe the CGP over time according to the methodology and conditions of the present study.

Urea coated with copper and boron may be a vehicle for selenium fertilization in grazing systems to improve both forage and animal productivity, and consequently, the nutritional quality of milk and meat. Urea is the most often used form of N fertilizer in Brazil; however, it can experience high losses by volatilization, primarily in pastures with high amounts of senescent biomass. The goal of this study was to evaluate losses by ammonia volatilization from urea coated with Cu, B, and Se. The fertilizer was applied to the soil surface under forage straw residues in cylindric glass chambers under controlled laboratory conditions. The treatments were urea (UR), urea coated with boric acid and copper sulfate (UBC), urea coated with boric acid, copper sulfate, and selenium (UBCS), and ammonium sulfate (AS). Measurements were recorded at regular intervals after fertilizer application for 27 days. High losses occurred from ammonia volatilization of amidic-N sources in the initial days after fertilizer application. The total loss of N by ammonia volatilization according to fertilizer treatment was UR > UBC = UBCS > AS. Urea lost by ammonia volatilization accounted for up to 50% of the N applied, although losses from coated urea treatments UBC and UBCS were 11.45% lower than that of urea. The Cu and B in the coated urea reduced losses by ammonia volatilization and the inclusion of Se had no effect. It is suggested that Se may be added to the Cu and B coating of urea to reduce ammonia volatilization.

This study aimed to determine the frequency of Pseudomonas fluorescens, P. putida, and P. aeruginosa in refrigerated raw milk; their proteolytic potential; and your association with the aprX gene. Of the 173 isolates confirmed as belonging to Pseudomonas spp., 37% were P. fluorescens, 25.4% P. putida, and none belongs to P. aeruginosa. The aprX gene was distributed proportionally between P. putida (68%) and P. fluorescens (75%), but it was not associated with low or high proteolytic potential in both species. P. putida (16) and P. fluorescens (14) isolates with no aprX gene identified also had proteolytic potential. Considering the synthesis of proteases other than AprX by the isolates under study, we concluded that P. fluorescens and P. putida represented 62.4% of the Pseudomonas genus, with high probability of having the aprX gene and proteolytic potential. However, there was no association between the deteriorating potential with the presence of the aprX gene.
Afwijzing verzoek tot beëindiging gezag van een ongeboren baby: Een verstandelijke beperking van ouders is op zich geen bepalende factor voor falend ouderschap

Afwijzing verzoek tot beëindiging gezag van een ongeboren baby

De Raad voor de Kinderbescherming verzoekt de beëindiging van het ouderlijk gezag van een ongeboren baby omdat de ouders een verstandelijke beperking hebben. Volgens de Raad mist de moeder vanwege haar verstandelijke beperking de sensitiviteit die nodig is voor de opvoeding. De moeder heeft een beroep gedaan op artikel 23 VN-verdrag inzake de Rechten van Personen met een Handicap (IVRPH). Daarin staat dat een kind niet gescheiden mag worden van zijn ouders enkel op basis van een handicap van de ouders en dat alle passende hulp geboden dient te worden om de opvoeding, eventueel met ondersteuning, mogelijk te maken. Rechtbank Amsterdam (ECLI:NL:RBAMS:2019:3375) wijst het verzoek af. De rechtbank kijkt naar de meerwaarde van de toepassing van dit verdrag ten opzichte van reeds bestaande bepalingen in internationale verdragen.

Design of a didactical resource to introduce chemical formulas in secondary school
Authors: Canac Sophie , Kermen Isabelle
Published: June 2020

This paper presents the research conducted to create a history-of-science-based resource that would introduce students to chemical formulas in secondary education in France. This elaboration is based on theoretical frameworks dealing with educational reconstruction of teaching-learning sequences and on the analysis of teaching practices. Preliminary empirical investigations conducted with students and some teachers show the need to articulate the registers of models, reality and language at the submicroscopic and macroscopic levels for learning the concepts of chemical change and chemical reaction. The first part of the resource is implemented in the classroom. The second part that allows to write the reasons justifying the chemical formulas is rejected by two teachers. This leads to a first proposal of the evolution of the resource.
Perfiles del futuro profesorado de matemáticas a partir de sus competencias profesionales

Published: June 2020

El objetivo de este artículo es identificar los perfiles del futuro profesorado de matemáticas a partir de su percepción sobre la adquisición de competencias, relacionándolos con la formación previa. Mediante un cuestionario on-line se recogieron datos de profesores de matemáticas en formación o recientemente egresados del Máster en Formación del Profesorado de Educación Secundaria de distintas universidades españolas. El análisis ha permitido identificar tres perfiles que tienen diferentes correlaciones con la percepción de haber adquirido las competencias de conocimiento matemático y pedagógico-matemático. Los resultados son coherentes con el modelo teórico utilizado para describir el conocimiento del profesorado de matemáticas. Este estudio justifica la necesidad de diseñar e implementar intervenciones que mejoren las debilidades de cada uno de estos perfiles durante el periodo de formación inicial docente.
Contemporary directions of application of low power ultrasounds in anticancer therapy

Published: June 2020

In the recent years, research has been conducted on the role of ultrasounds (US) in anticancer therapy. Although the mechanisms of impact on cancer cells have not yet been fully understood, it is known that the best results are obtained using low power ultrasound. Currently applying ultrasounds to organisms is considered in three areas of influence: thermal (thermic effect), cavitation (cavitation effect), other than thermal and cavitation ones (non-thermal, non-cavitation effect). Under the influence of ultrasonic wave with low power, the absorption of drugs is increased as well as of anti-angiogenic activity. Sonodynamic therapy is aimed at destroying dividing cancer cells through the formation of free radicals in the cavitation mechanism and in the presence of sonosensitizers. At the same time under the influence of US, local hyperthermia is generated. In vivo studies showed a synergistic increase in cytotoxicity due to the effects of ultrasonic hyperthermia and adriamycin. The thermal effect and inertial cavitation are described as two factors induced by US, which may lead to damage to the vascular network within the neoplastic lesion. A proportional increase in tumor echogenicity to the frequency range of the applied ultrasound wave has been demonstrated. The strategy of combining US with photosensitizers, chemotherapeutics or contrast agents is gaining more and more recognition. Obtained results from inter developed studies on antineoplastic sonodynamic therapy indicate that it may become a new additional cancer treatment strategy.
