title: Extraction and evaluation of tannin from green coconut mesocarp

description: ABSTRACT The development of alternatives for reuse of coconut shell allows inadequate solid residues disposal reduction and provides a novelty option close to the production sites. This paper aims to evaluate the tannin extraction potential of the green coconut mesocarp, as well as its adhesive capacity. Tannin extraction was performed with sodium sulfite diluted in water at 0%, 1%, 5% and 8% concentrations. It was observed which extraction resulted in better yield and characteristics to be used as an adhesive agent. The concentration of sodium sulfite at 5% allowed higher yields of tannin extraction. When compared to phenol formaldehyde, the tannin had similar adhesive characteristics such as 153.84 cp viscosity and 54.57% solid content. For the FT-IR spectroscopy analysis, dry samples of the coconut mesocarp were used. The peaks observed in the infrared spectrum of the green coconut mesocarp are characteristic of tannins found in biomass, presenting desirable chemical characteristics to be used as an adhesive agent. The coconut mesocarp is a material with potential for tannin extraction, making it suitable to be used in the gluing of panels.

title: Which antiretroviral regimen is associated with higher adherence in Brazil? A comparison of single, multi, and dolutegravir-based regimens

description: Abstract: We evaluated adherence to highly active antiretroviral therapy (HAART) and its associated factors according to the type of regimen in patients initiating treatment in Belo Horizonte, Minas Gerais State, Brazil. We measured adherence using the eight items Morisky Therapeutic Adhesion Scale (MMAS-8) and compared the use of “backbone” tenofovir/lamivudine plus efavirenz one tablet once-daily (STR) or dolutegravir in multi-tablet once-daily (MTR-DTG), or other multi-tablet regimens (MTR-other). We conducted a multivariate logistic regression analysis to address factors associated with adherence. A total of 393 patients were included, 254 used STR, 106 MTR-DTG, and 33 MTR-other. The overall adhesion rate was 44.8% (95%CI: 39.4; 50.1), 50% for MTR-DTG, 43.3% for STR and 39.4% for MTR-other. Multivariate analysis showed a higher chance of adherence among patients using MTR-DTG, those who received and understood counseling about their treatment and with a higher quality of life. Prior use of illicit drugs in the lifetime was associated with poorer adherence. Overall adherence was low, highlighting the need for strategies focusing on counseling about medicines and substance use. Pill burden was not an issue for patients using MTR-DTG once-daily, who achieved better results.

title: Post pollination events in a self-sterile hexaploid monoembryonic lineage of Handroanthus serratifolius (Vahl) S. Grose (Bignoniaceae)

description: ABSTRACT In diploid late-acting self-incompatible (LSI) species of Bignoniaceae, self-pollinated pistils show a marked delay in ovule penetration by pollen tubes, followed by delayed, but otherwise normal, initial stages of endosperm development and subsequent pistil abscission. Most polyploid species of Bignoniaceae are apomictic and set selfed fruits with viable polyembryonic seeds carrying adventitious embryos. Handroanthus serratifolius is a polyploid species with sporophytic apomictic individuals that produce polyembryonic seeds after either self- or cross-pollination, and other LSI individuals that produce exclusively monoembryionic seeds. Our aim was to determine whether self-sterility events in the latter are similar to those observed in other diploid LSI species of Bignoniaceae. No conspicuous differences in the progress of ovule penetration, fertilization and early stages of endosperm development were observed between selfed and crossed pistils, which contrasts with the marked delay observed in these events after self-pollination in diploid LSI species of the family. Adventitious embryo precursor cells (AEPs) were observed in some ovules, but they apparently do not develop into embryos. We believe that the AEPs in these plants represent a ‘potential’ for sporophytic apomixis, which would explain the similar behaviour of post-pollination events in selfed vs. crossed pistils despite their inability to set fruits after selfing.

title: Experimental study of the influence of the addition of polypropylene microfibers and cure on the surface hardness of concrete floors

description: ABSTRACT Failures of dosing and execution of concrete floors, constantly lead to the emergence of pathological manifestations. Therefore, it is indispensable to know the factors that influence the behavior of the concrete or alter its characteristics, as well as the use of quality manpower. This study evaluated the influence of the addition of polypropylene microfibers in the contents of 0 g/m3, 600 g/m3 and 900 g/m3 and of different curing conditions (without cure, wet cure and wet cure after three days of exposure) in concrete used in floors. For that, tests of bleeding, compressive strength and surface hardness by rebound hammer were per-formed. The results indicate that the use of microfibers significantly influenced the bleeding and the compressive strength, although the surface hardness was not affected directly by this material nor by the type of cure. In general, it can be said that of the polypropylene microfiber contents evaluated, the 600 g/m3 content is the most suitable for addition in the concrete, presenting better performance in the analyzed properties. It is possible to affirm still that the cure, although not having caused significant influence on the surface of the concrete, is a factor of extreme importance for its mass properties.

title: Genetic diversity and nonparametric statistics to identify possible ISSR marker association with fiber quality of pineapple

description: Abstract: Due to the increasing search for renewable resources, plant fibers have become an alternative when creating new products. Studies demonstrate the potential use of pineapple fibers in composites. The objective of this work was to evaluate the genetic diversity and verify any association between ISSR (Inter Simple Sequence Repeats) bands and quality of pineapple fibers for use in cements in the civil construction. The study analyzed the genetic variability of 11 pineapple genotypes, as well as the possible association of 131 bands from 16 ISSR markers with fiber quality characteristics. Eleven bands were selected based on their high correlations (0.64578* to 0.72457*) with three fiber quality variables. Of these, two bands were purified, sequenced, and blasted against sequences in GenBank at NCBI. These markers can be used in marker assisted selection to genetically improve the quality of pineapple fiber. Bands that returned no hits in the NCBI BLAST search can be deposited as new sequences in the GenBank. Therefore, the SCAR markers, once validated, can be useful in pineapple genetic breeding programs worldwide by using molecular marker assisted selection for fiber resistance, which could subsidize the development of more promising genotypes for industrial use and contribute to the sustainability of this new production sector.

title: Reconstruction of the Late Pleistocene to Late Holocene vegetation transition using packrat midden and pollen evidence from the Central Mojave Desert

description: ABSTRACT The Mojave Desert of the American West is characterized by plant species that reflect a unique mixture of winter precipitation and summer monsoon climate. Currently, the Mojave Desert experiences a strong summer monsoonal pattern with weak winter precipitation. Data from pollen and packrat midden analyses have revealed a history of Mojave Desert vegetation during the transition from the late Pleistocene to late Holocene (~17500 Cal. years B.P. to ~ 1200 Cal. years B.P.) that highlight a summer dominated monsoonal pattern, similar to those in the greater American Southwest. We compare pollen data from a lava tube in the Cima volcanic field, located in south-central region of the Mojave Desert, with plant macrofossil data from several woodrat midden localities in the region. The record for the Cima volcanic field reveals a vegetation history spanning the last ~ 8300 Cal. years B.P., with data from ancient woodrat middens detailing the record from ~17500 Cal. years B.P. to 7,800 Cal. years B.P. A Bryson macro-physical climate model for the transition from the late Pleistocene to the Late Holocene was created and compared to our findings to assess possible relationships between climatic variations and the arrival of diagnostic plant species within the Mojave Desert.

title: Chlorophyll a fluorescence and leaf temperature are early indicators of oil palm diseases

description: ABSTRACT Bud rot (BR) caused by Phytophthora palmivora and lethal wilt (LW) whose causal agent is unknown, are two diseases currently posing a threat to the oil palm ( Elaeis guineensis . Jacq) industry. BR, first reported in 1964, has destroyed more than 85,000 ha. LW, first reported in 1994 in the Llanos Orientales in Colombia, has destroyed more than 5,000 ha. Chlorophyll a fluorescence is useful as a provider of information about the efficiency of the photosynthetic process when plants are subjected to biotic or abiotic stresses. Oil palms affected by BR and LW showed anomalies in the photosynthetic system, manifested by reductions in Fv / F M and ΦPSII. Changes in ΦPSII, variable fluorescence yield ( Fv ) and maximum fluorescence in light-adapted leaves ( F M ’ ) were observed from the start of BR infection. The most sensitive and early indicators of LW disease were leaf temperature and basal fluorescence ( F 0 ). Fv/F 0 significantly changed in diseased palms, indicating problems with movement of electrons through the electron transport chain. Leaf temperature changed in response to both diseases, but variation was greater in LW. We concluded that damage to the photochemical system caused by the diseases affected the processes by which the plant captures and transports energy, causing a physiological imbalance in the plant reflected in the observed variations in chlorophyll a fluorescence and leaf temperature. The two parameters began to change early in the onset of BR and before visual symptoms appeared in LW, which is very important to the management of both diseases, the foundation of which is early detection.

title: Time trends in morbid obesity prevalence in the Brazilian adult population from 2006 to 2017

description: This study was an assessment of time trends in morbid obesity prevalence in the adult population in Brazil’s state capitals from 2006 to 2017. A cross-sectional study was performed with data from the Risk and Protective Factors Surveillance System for Chronic Noncommunicable Diseases Through Telephone Interview (Vigitel), analyzed by simple linear regression. The results showed an upward trend in morbid obesity prevalence in Brazil. Women showed higher prevalence rates (1.3% in 2006 and 1.9% in 2017) when compared to men (0.9% and 1.4%). The 25-44-year age bracket showed an upward trend from 0.9% to 2.1% (p &lt; 0.001). There was an increase in morbid obesity in all levels of schooling and all regions of Brazil. The state capitals with upward trends in males were Campo Grande, Curitiba, Fortaleza, Macapá, Manaus, Palmas, Porto Velho, Rio Branco, and Teresina. In females, they were Belo Horizonte, Campo Grande, Rio de Janeiro, and Teresina. The growth in morbid obesity in Brazil sounds a warning on the urgent need to adopt measures to detain it, such as regulation of ultra-processed foods and health education measures for the entire population.

title: Pollen morphology and exine ultrastructure of Brasiliocroton P.E. Berry & Cordeiro (Euphorbiaceae)

description: ABSTRACT The present study aimed to morphologically characterize the pollen grains of species of Brasiliocroton mamoninha and B. muricatus in order to expand palynological knowledge of the group and provide additional micromorphological information useful for studies of the relationships within Crotoneae. Polleniferous material was acetolysed and described using light, scanning electron and transmission microscopy. The pollen grains of the two species of Brasiliocroton were apolar, spherical, inaperaturate and medium-sized with a Croton ornamentation pattern. The Croton pattern of B. mamoninha is formed by subtriangular pila, &gt;5-plicate with pointed apices, while for B. muricatus it is formed by subcircular to circular pila, &lt;5-plicate with rounded apices. Ultrastructural analysis revealed a stratified sexine in both species, whereas variation in the pattern of deposition of the foot layer allowed the species to be palynologically distinguished from each other. The composition of the Croton pattern of ornamentation, the morphology of the ultrastructure of the wall and the range of variation in the diameter of the pollen grains differed between the studied species, and thus are diagnostic characters. Pollen morphology allowed the two species of Brasiliocroton to be palynologically separated, and provided data that will be useful for taxonomically circumscribing these taxa.

title: Decision-making in teaching hospitals: between formalism and intuitive synthesis

description: Abstract This multiple-case study analyzes how middle managers (MM), from their strategic roles, associate rational and intuitive decisions in the strategic decision-making process (SDM) in public teaching hospitals (PTH). Data was collected through interview and document analysis. Data analysis occurred through constitutive elements of analysis: rationality, intuitive synthesis, and middle managers. The research found that, when articulating with the organization’s upper management, the MM takes the roles of synthesizing information and championing alternatives, emphasizing rational decisions. When articulating with the lower-level management, the MM plays the roles of facilitating and implementing deliberate strategy, emphasizing intuitive decisions. As a contribution to the field, the study presents the objective and inter-subjective dimensions in the SDM process, evidencing the complexity of the strategic roles of the MM in deliberate and emergent situations in PTH.
