title: Differential incidence of the lemma on seed germination among different Paspalum dilatatum genotypes

description: Abstract: Paspalum dilatatum Poir. is a promising perennial summer grass forage for temperate regions, but among other factors, slow stand establishment has hindered its adoption. One of the reasons may be seed dormancy. Intraspecific variability in seed dormancy has been reported in P. dilatatum, but the mechanisms underlying this variability remain unclear. In this paper, we focus on the role of seed external covering structures on germination, particularly the lemma. Seeds of apomictic and sexual biotypes of P. dilatatum were subjected to acid scarification and removal of the lemma to study their germination, imbibition rate and sensitivity to ABA. Seeds without lemma showed higher germination than other treatments in dormant genotypes. We found that the lemma delayed but did not prevent water uptake in any genotype. Comparing sexual biotypes, P. dilatatum subsp. flavescens showed higher lemma-imposed dormancy than P. dilatatum “Virasoro”, and also higher seed dormancy at the caryopsis level. The thickness of the lemma was not different between these biotypes, so this trait did not explain differences in dormancy. Intraspecific variability of seed dormancy in this species may be attributable to the lemma incidence, however differences in the caryopsis component of seed dormancy should be considered.

title: Technologies for rational water use in Brazilian agriculture

description: Abstract Brazil has the highest water availability of any country in the world. Nearly 20% of all the world's rivers flow on Brazilian soil. Brazil's herds of cattle, pigs and poultry are among the largest in the world, and the country uses irrigated agriculture extensively, which accounts for most water consumption (approximately 70% of the water consumed in the world). The Brazilian Agricultural Research Corporation (Embrapa), the largest and most important public institution of Brazilian agricultural research, has attempted to develop environmental technologies in order to minimize the impact caused by the scarcity and pollution of water resources. This paper describes the technologies this institution offers to different regions. For this purpose, a descriptive and exploratory study was conducted in various Embrapa research units. The results showed that research on the rational use of water in agriculture has intensified since the early 2000s. However, the pace of growth in agricultural activities and their impact is much greater than that of the generated technologies, demonstrating the difficulty in striking a balance in this relationship. Furthermore, it is clear that that water scarcity and the increasing pollution of shallow and deep waters are complex issues with no short-term solution.

title: Central Santa Catarina coastal dunefields chronology and their relation to relative sea level and climatic changes

description: ABSTRACTDuring the past decades, there have been contrarian explanations for the formation and stabilization of coastal dunefields: while many authors believe the dunes formation would be enhanced by falling sea level, others argue that a rising or stable sea level context would be favorable. For Brazilian coastal dunefields, the second hypothesis seems to be more consistent with the luminescence ages found so far; however, most of these data were obtained without using the SAR protocol. Another point of concern is the role of climate change in the aeolian system, which is still not very clear. The aim of this paper is to try to clarify these two questions. To this end, five coastal dunefields were selected in central Santa Catarina coast. The remote sensing and dating results allowed the discrimination and mapping of at least four aeolian generations. Their age distribution in relation to the global curve of relative sea level variation during the Late Pleistocene allows us to suggest that the formation of Aeolian dunefields in the coastal context is supported by stable relative sea level. However, relative sea level is not the only determinant for the formation and preservation of the aeolian coastal dunes. Evidences of climatic control indicate that the initiation of dunefields would be favored by periods of less humidity while their stabilization would occur preferably during the periods of rain intensification, connected to monsoon activity.

title: Use of water restriction in the inoculation of carrot seeds

description: Abstract: This study aimed at evaluating the method of inoculation of carrot seeds in a potato-dextrose-agar medium (PDA) added of mannitol. Alternaria radicina was the fungus chosen to test such methodology. The osmosis-controlling agent was employed to obtain the osmotic potentials of 0.6 MPa, 0.8 MPa, 1.0 MPa and 1.2 MPa. In comparison with the control treatment, no significant mycelial growth inhibition was noticed at any of the osmotic potentials considered. The seeds were distributed over the fungal colonies for infection, where they remained for 48, 72, 96, 120 and 144 hours, at the osmotic potentials of 0.0 MPa (control), 0.6 MPa, 0.8 MPa, 1.0 MPa and 1.2 MPa, respectively. Tests of germination, sanitization and emergence were performed to evaluate the effects of colonization. Regarding the germination, the different osmotic potentials resulted in similar percentages of abnormal seedlings and dead seeds. As for the sanitization testing, higher infection rates were observed at the osmotic potentials of 1.0 MPa and 1.2 MPa. The lowest percentage of emergence was found at -1.2 MPa, therefore suggesting that this osmotic potential (produced with mannitol) might be used for infecting carrot seeds for research purposes.

title: ECONOMIC POLICIES AND TECHNOLOGY INNOVATION

description: Abstract Considering important studies on innovations such as those by Schumpeter (1982), Dosi (1982) and, especially, Mazzucato and Penna (2016), in which they analyzed Brazil's system of innovations, pointing out the macroeconomic regime as a major weakness, this paper’s objective is to analyze and discuss the relationships between selected macroeconomic variables (such as exchange, interest and inflation rates and industrial production) and innovations in Brazil. For this, a vector of error correction (VEC) model is estimated. The results found a negative relationship between innovation and the macroeconomic variables of interest and inflation rates, a positive relationship with industrial production and with innovation itself, and a negative relationship with a short-term exchange rate depreciation immediately after the shock but becoming positive after a few periods.

title: Liquid whey protein concentrates as primary raw material for acid dairy gels

description: Abstract The replacement of dehydrated products such as whey protein concentrates and isolates (WPC and WPI) by liquid whey protein concentrates (LWPC) obtained by ultrafiltration can be an excellent alternative for the production of innovative dairy products. Thus, the aim of this work is to study the gelation properties of LWPC as raw material for acid-induced dairy gels. Acid-induced gels were produced with non-defatted LWPC, with or without fortification with skimmed milk powder (SMP), by bacterial fermentation and by glucono-δ-lactone (GDL) acidification. The fermented systems (yogurt type acid gels) produced weaker gel structures than the equivalent chemically acidified gels (dessert type acid gels). It was also observed that molecular rearrangement continues during cold storage and that fortification with SMP favoured gelation. Whey-based dairy gels obtained by fermentation or by glucono-δ-lactone acidification presented viscoelastic behaviour, appealing functional and nutritional properties, and their utilization can effectively contribute to the reduction of waste.

title: THE HOUSING ISSUE IN BRAZIL

description: ABSTRACT This article discusses housing in Brazil, which is one of the main urban problems in contemporary times. Housing is a high cost commodity with selective access, thus excluding economically disadvantaged social groups. The segregating character that permeates the housing issue is evidenced as a historically established process in our capitalist society. Therefore, the main objective of this research was to analyze the housing situation in Brazil, in view of Brazilian urbanization and the commercialization of urban land and housing, considering that housing is a key issue in public policies, projecting itself as a material form of social inclusion. Thus, this research made it possible to perceive that the housing problem in Brazil has not been totally solved yet. To this end, the provision of housing for low income families is indispensable, through well-developed and effective public housing policies that guarantee social development, combat poverty and seek a better quality of life for all citizens.

title: The professionals’ perspective on the patient discharge process of the Caps-AD: criteria and difficulties

description: ABSTRACT The aim was to understand how the discharge process of patients at the Psychosocial Care Centers for Alcohol and Drugs (Caps-AD) occurs, from the professionals’ perspective. The discharge criteria used by the institutions (Caps-AD), by the professionals and the difficulties encountered during the discharge process were investigated. The methodology was qualitative, through in-depth interviews carried out with sixteen professionals working in five Caps-AD at São Paulo. The recruitment was by snowball technique, and the material was transcribed and subjected to content analysis. It was observed that there is no standardization and clarity of the discharge criteria at the Caps-AD. The professionals considered as discharge criteria: change in the pattern of use of the substance, social reintegration, improvement in psychological functioning and coping skills of the individual and achievement of established goals. Most of the difficulties encountered were the differences in the team, professionals’ omnipotence, difficulties related to the rupture of the bonds, institutional dependence, patient instability and difficulties in health network articulation. The results express the complexity and amplitude of the discharge issue in Caps-AD, since the process is characterized by the articulation of social, economic, political, subjective and institutional dimensions.

title: Echocardiographic Assessment of Right Ventricular Function by Two-Dimensional Strain In Patients with Left-Sided Valvular Heart Disease: Comparison with Three-Dimensional Echocardiography

description: Abstract Background: Right ventricular (RV) dysfunction is a well-known predictor of mortality in patients with valvular heart disease (VHD). The assessment of RV function is often difficult due to complex geometry and hemodynamic factors. We aim to analyze RV function in patients with severe mitral and/or aortic valve disease using two-dimensional strain (2DS) imaging and conventional echocardiographic parameters, comparing it with right ventricular ejection fraction (RVEF) measured by three-dimensional echocardiography (3DE). Methods: Fifty-three patients with severe mitral and/or aortic VHD underwent complete transthoracic echocardiogram in the preoperative setting for cardiac surgery, including conventional echocardiographic parameters of RV function and speckle-tracking derived 2DS indices: RV global longitudinal strain (RVGS) and RV free wall longitudinal strain (RVFWS). Conventional echocardiographic and 2DS parameters were compared with real-time 3DE RVEF using Spearman correlation test. For comparison between two groups of patients based on the presence of RV dysfunction (normal RVEF ≥ 44% - A, abnormal RVEF &lt; 44% - B), we used nonparametric Mann-Whitney U test. ROC (receiver operating characteristic) curve analysis was used to assess the clinical utility of all RV function variables in defining RV dysfunction. P values &lt;0,05 were considered statistically significant. Results: We found a significant correlation between all parameters and RVEF (p&lt;0.05), with best results for RV fractional area change (FAC), RVGS, and RVFWS. Dividing the population into two-groups based on RVEF, we found 14 patients with RV dysfunction (27.4%), and significant differences between the groups for all RV function variables. For detection of RV dysfunction defined by 3DE, ROC curve analysis showed the best area under the curve (AUC) for RVGS (0.872), RVFWS (0.851) and FAC (0.932). Conclusions: We observed significant correlation between RVGS, RVFWS and RVEF, with good accuracy in detecting RV dysfunction, comparable to FAC and better than other conventional parameters of RV function assessment. The evaluation of RV myocardial deformation with 2DS may have additional diagnostic and prognostic value in patients with severe left-sided VHD.
