Efeito alelop?tico de extrato de centeio na germina??o de sementes e crescimento de pl?ntulas de cenoura e beterra

Allelopathy may inhibit or stimulate plant development. The use of plants to cover the soil can result in allopathic effects on the germination and early seedlings development of through the release of secondary (allochemical) metabolites. Thus, the present work aims to verify if the aqueous extract of rye exerts allelopathic action on germination and seedlings growth of beet and carrot. The experimental design was completely randomized, in a 2 x 4 factorial scheme (cultivars x concentrations), with five replications, for each species separately. Beet seeds, Early Wonder and Vermelha Comprida, and carrot seeds of Bras?lia Irec? and Kuronan cultivars were used. The extracts were prepared using whole rye plants, in concentrations of 0 (control), 25, 50 and 100%. The seeds were conditioned in gerbox plastic boxes, with germitest paper moistened with the extracts. The analyzed variables were: percentage of germination, of non-germinated seeds and abnormal seedlings, speed germination index, length of shoot and roots of seedlings, and seedling dry mass (shoot and roots). The data were submitted to analysis of variance and when this was significant, the regression analysis was performed. The increase in the concentration of aqueous extract of rye causes linear reduction of the germination of carrot seeds. Carrot seedlings growth is adversely affected by aqueous extract of rye. The aqueous extract of rye reduces the germination of beet seeds. Beet seedlings growth is affected by the rye extract, with variable effect as a function of the cultivar.A alelopatia pode inibir ou estimular o desenvolvimento de plantas. O uso de plantas para cobertura do solo pode resultar em efeitos alelop?ticos na germina??o e desenvolvimento de pl?ntulas atrav?s da libera??o de metabolitos secund?rios (aleloqu?micos). Assim, o presente trabalho teve por objetivo verificar se extrato aquoso de centeio exerce a??o alelop?tica na germina??o de sementes e crescimento de pl?ntulas de beterraba e cenoura. O delineamento experimental utilizado foi inteiramente casualizado, em esquema fatorial 2 x 4 (cultivares x concentra??es), com cinco repeti??es, para cada esp?cie separadamente. Foram utilizadas sementes de beterraba, das cultivares Early Wonder e Vermelha comprida, e sementes de cenoura das cultivares Bras?lia Irec? e Kuronan. Os extratos foram preparados utilizando-se plantas inteiras de centeio crioulo, nas concentra??es de 0 (testemunha), 25, 50 e 100%. As sementes foram acondicionadas em caixas pl?sticas do tipo gerbox, com papel germitest umedecido com os extratos. As vari?veis analisadas foram: porcentagem de germina??o, de sementes n?o germinadas e pl?ntulas anormais, ?ndice de velocidade de gemina??o, comprimento de parte a?rea e de ra?zes de pl?ntulas, e massa seca da parte a?rea e de ra?zes das pl?ntulas. Os dados obtidos foram submetidos a an?lise de vari?ncia e quando esta foi significativa procedeu-se ? an?lise de regress?o. O extrato aquoso de centeio interferiu de forma negativa na germina??o de sementes de cenoura e beterraba. O aumento da concentra??o de extrato aquoso de centeio causa redu??o linear da germina??o de sementes de cenoura. O crescimento de pl?ntulas de cenoura ? afetado negativamente por extrato aquoso de centeio. O extrato aquoso de centeio reduz a germina??o de sementes de beterraba. O crescimento de pl?ntulas de beterraba ? afetado pelo extrato de centeio, com efeito vari?vel em fun??o da cultivar

When university becomes the enemy: hate speech attacks on facebook

The extreme right hate speech propagated currently in Brazil addresses a broad social spectrum, from feminist movements to traditional communities. The academic community and higher education institutions are also targets, as they are identified as poles of democratic resistance. Specific hate speech towards academy in Brazil is the subject of this paper. The persecution of academic community and knowledge itself occurs through the discursive dispute especially on social networks, and thus in this analytical exercise, we looked up at Facebook's largest bolsonarista's group - the "Jair Bolsonaro Presidency Support Group", which brings together 317,000 members. We analyzed the memetic discourse on the page, focusing memes that were published between April and June 2019, thematizing higher public education, and presenting a bimodal verb-visual composition. These criteria led to the collection of 115 memes analyzed with the support of a QDA package. Analysis reveals the disqualification of university institutions and their actors through ironies, negative associations including stereotypes, simplification of debate to the shallower. Students are often associated with nudity as immorality, professors of indoctrination and ridicule, protesters of ignorance, or bad character. Political debate is reduced to extreme left-right polarization, with the criminalization of the left

Expresiones territoriales y urbanización popular en la posconvertibilidad: Aportes a una caracterización socio-espacial y socio-urbana del Conurbano bonaerense

Se sostiene que con los importantes cambios políticos y económicos que tuvo la Argentina con el fin de la convertibilidad se pueden observar expresiones territoriales en el Conurbano bonaerense frente a las reconfiguraciones sociales de las diferentes clases, en especial de los sectores populares. El artículo propone una contribución al campo de los estudios urbanos y buscará aportar a la comprensión del proceso de urbanización popular en la posconvertibilidad, identificando algunas características territoriales del Conurbano en este periodo. Se trata de un primer avance de un proyecto de investigación de tesis doctoral que tiene como uno de los objetivos construir una amplia mirada sobre la realidad y las dimensiones socio-espaciales y socio-urbanas de esos territorios y su relación con el espacio metropolitanoIt is argued that with the important political and economic changes that Argentina had with the end of convertibility can be observed territorial expressions in the Buenos Aires Conurbano (outer Buenos Aires) against the social reconfigurations of the different classes, in special of the popular classes. The article proposes a contribution to the field of urban studies and will seek to contribute to the understanding of the process of popular urbanization in the posconvertibility, identifying some territorial characteristics of the conurbation in this period.

Determinantes de la calidad de vida relacionada a la salud en pacientes atendidos en ambulatorios con insuficiencia cardíaca

This descriptive and exploratory study analyzed variables associated with health-related quality of life among 130 outpatients. Health-related quality of life was measured through the Minnesota Living with Heart Failure Questionnaire. Significant associations were found between patients’ health-related quality of life and their age (r=-0.177; p=0.044), vitality (r=-0.625; p=<0.001) as well as mental health (r=-0.672; p=<0.001), which are both SF-36 domains. The linear regression showed that heart failure symptom severity, vitality and mental health explained 54% of HRQOL measurement variation. To control symptoms and preserve good mental well-being are important to maintain health-related quality of life and to deliver effective heart failure care.Trata-se de estudo descritivo e exploratório que analisou as variáveis associadas à qualidade de vida relacionada à saúde (QVRS), de 130 pacientes com insuficiência cardíaca, em seguimento ambulatorial.

Cosiendo los retazos de la economía popular y en el mientrastanto incomodando al sentido común

This article presents the results of a territorial research whose empirical purpose is those areas of the Buenos Aires Conurbano (outer Buenos Aires) where people has been developing land and housing access strategies outside the formal real estate market: villas, settlements and neighborhoods of the state housing and urbanization policy. It began in 2011 and provides weighted primary statistical information on more than 15,000 homes and households and 65,000 people in 14 neighborhoods. This research work is concerned with the study of social reproduction strategies of households in the popular economy, which has required the construction of conceptual categories that enable the dialogue between theory and empire. These categories are sketches or questions in some cases and in others they have already reached a certain degree of maturity, and are the product of the articulation of the individual research lines of the team members, while others are the basis for collective research.Fil: Vio, Marcela.

New Equation for Prediction of Reverse Remodeling after Cardiac Resynchronization Therapy

Objectives: To integrate data from two-dimensional echocardiography (2D ECHO), three-dimensional echocardiography (3D ECHO), and tissue Doppler imaging (TDI) for prediction of left ventricular (LV) reverse remodeling (LVRR) after cardiac resynchronization therapy (CRT). It was also compared the evaluation of cardiac dyssynchrony by TDI and 3D ECHO. Methods: Twenty-four consecutive patients with heart failure, sinus rhythm, QRS = 120 msec, functional class III or IV and LV ejection fraction (LVEF) = 0.35 underwent CRT. 2D ECHO, 3D ECHO with systolic dyssynchrony index (SDI) analysis, and TDI were performed before, 3 and 6 months after CRT. Cardiac dyssynchrony analyses by TDI and SDI were compared with the Pearson's correlation test. Before CRT, a univariate analysis of baseline characteristics was performed for the construction of a logistic regression model to identify the best predictors of LVRR. Results: After 3 months of CRT, there was a moderate correlation between TDI and SDI (r = 0.52). At other time points, there was no strong correlation. Nine of twenty-four (38%) patients presented with LVRR 6 months after CRT. After logistic regression analysis, SDI (SDI &gt; 11%) was the only independent factor in the prediction of LVRR 6 months of CRT (sensitivity = 0.89 and specificity = 0.73). After construction of receiver operator characteristic (ROC) curves, an equation was established to predict LVRR: LVRR =-0.4LVDD (mm) + 0.5LVEF (%) + 1.1SDI (%), with responders presenting values &gt;0 (sensitivity = 0.67 and specificity = 0.87). Conclusions: In this study, there was no strong correlation between TDI and SDI. An equation is proposed for the prediction of LVRR after CRT. Although larger trials are needed to validate these findings, this equation may be useful to candidates for CRT. (Echocardiography 2012;29:678-687)SOCESP (Sao Paulo Society of Cardiology
