title: Rhizosphere bacterial and fungal communities of healthy and wilted pepper (Capsicum annuum L.) in an organic farming system

description: ABSTRACT: Rhizosphere microorganisms play an important role in the growth and health of plants. Around the world, diverse soil-borne pathogens attack Capsicum annuum causing significant damage and economic losses. This study determined whether the diversity and composition of microbial communities in the rhizosphere soil of C. annuum plants is significantly changed by wilt disease. We used the 16S rRNA gene for bacteria and the internal transcribed spacer region for fungi to characterize the rhizosphere microbiomes of healthy and wilted plants. The most abundant bacterial phyla were Proteobacteria and Gemmatimonadetes, while the most abundant fungal phyla were Ascomycota and Mucoromycota. The bacterial α-diversity did not show significant differences in richness and diversity, but did show a significant difference in evenness and dominance of species. Rare taxa were present in both healthy and wilted conditions with relative abundances &lt; 1%. In the fungi, all evaluated estimators showed a significant reduction in the wilted condition. The β-diversity showed significant differences in the structure of bacterial and fungal communities, which were segregated according to plant health conditions. The same occurred when comparing the alpha and beta diversity of this study based on organic agriculture with that of other studies based on conventional agriculture. We observed a significant difference with estimators analyzed by segregating rhizosphere communities depending on the farming method used. Finally, the differential abundance analysis did not show significant results in the bacterial communities; however, in the fungal communities, Fusarium, Thanatephorus, Rhizopus, Curvularia, Cladosporium, and Alternaria were more abundant in the rhizosphere of wilted than healthy plants. Species from these genera have been previously reported as phytopathogens of several plants, including C. annuum.

title: Genetic comparison of populations of Piaractus brachypomus and P. orinoquensis (Characiformes: Serrasalmidae) of the Amazon and Orinoco basins

description: Abstract Recently, the large migratory fishes of the family Serrasalmidae (Piaractus brachypomus and P. orinoquensis) were described as restricted to the Orinoco and Amazon basins. Both species provide important ecosystem services. They also are an important fisheries resource, which has caused that their populations have decreased in recent years. National fisheries policies still consider both species as one, which leads to inefficiencies in their management and conservation. The aim of this study was to genetically characterize these two species, using microsatellite and mitochondrial markers, and discuss the implication of these results for conservation and management. We found that both species have moderate genetic diversity and varied patterns of genetic distribution in the fluvial landscape. Piaractus brachypomus presented genetic diversity of A=6.5; He=0.72; Ho=0.67; Ĥ=1.000; ᴫ=0.0092, three management units related to the evolutionary process of the Amazon basin and the effective sizes of local populations were smaller compared to P. orinoquensis, which presented genetic diversity of A=6.1; He=0.66; Ho=0.55; Ĥ=0.968; ᴫ=0.010 and comprises only one management unit. These results demonstrate the need to design management policies that focus on species and geographically restricted populations.

title: Dormancy overcoming in seeds of Myrciaria glomerata O. Berg.

description: Abstract Myrciaria glomerata O. Berg. (Myrtaceae) is a fruit tree native to the Brazilian Atlantic Forest with potential for use as food and medicine, besides having good ecological potential. However, this species is limited by low germination rates. Thus, this study aimed to evaluate different methods to overcome dormancy in seeds of M. glomerata and to improve seedling vigor. For this, two experiments were conducted. In Experiment 1, seven treatments were tested: a control treatment, immersion in water at 100 ºC for 30 seconds, immersion in concentrated sulfuric acid (H2SO4) for 1 and 5 minutes, immersion in an aqueous solution of gibberellic acid (GA3) at the concentrations of 250 and 500 mg L-1 for 24 h, and seeds homogenized with an aqueous solution of Stimulate® at a concentration of 5 mL kg-1 seed. In Experiment 2, six doses of Stimulate® were tested: 0, 5, 10, 15, 20, 25, and 30 mL kg-1 seed. The immersion of seeds in 250 and 500 mg L-1 GA3 contributes to increase germination rates, seed length, fresh mass, and dry mass compared to the control and the other methods tested. Immersions in water at 100 ºC and in H2SO4 are not recommended for M. glomerata. The treatment with Stimulate® at 15–25 mL kg-1 seed increased all characteristics analyzed. Immersion in 250 mg L-1 GA3 and Stimu-late® at 20–25 mL kg-1 seed efficiently stimulated seeds to overcome dormancy in M. glomerata, as well as improved seedling vigor.

title: Antibiotic susceptibility patterns of bacterial isolates of patients with upper respiratory tract infections

description: Abstract To evaluate the antibiotic susceptibility patterns in URTIs reporting to tertiary hospitals of Lahore. A cross-sectional study employing 259 culture sensitivity reports obtained from tertiary care hospitals of Lahore. Using SPSS, descriptive statistics were used to estimate frequencies and percentages. In URTIs, S. aureus (5%) was the frequent gram-positive isolate followed by MRSA (1.5%) and MSSA (1.5%), while P. aeruginosa (15.8%) was the prevalent gram-negative isolate followed by Klebsiella (13.1%) and E. coli (6.9%). Against P. aeruginosa, ceftazidime (7.7%), cefuroxime/ceftriaxone (4.6%), amoxicillin (4.3%) and ciprofloxacin (4.2%), were tested resistant, while imipenem (11.2%), ciprofloxacin (9.2%), amikacin (9.2%), meropenem/ levofloxacin/gentamicin (8.1%) and piptaz (6.9%) were found sensitive. Against Klebsiella, carbepenems (7.3%), amikacin (6.5%), ciprofloxacin (5.4%) and gentamicin (5%) were tested sensitive, whereas, ceftazidime (8.5%), ceftriaxone (5.8%), cefaclor (5.5%), ampicillin (4.6%), co-amoxiclave (4.2%) and ciftazidime/ciprofloxacin (3.8%) were found resistant. Overall, imipenem (35%), meropenem (30.8%) and amikacin (31.9%) were the three most sensitive antibiotics, while ceftazidime (25.4%), ceftriaxone (19.2%) and ampicillin (18.5%) were the three most resistant antibiotics. Data suggested that P.aeruginosa and Klebsiella, were the most frequent bacterial isolates in URTIs of Lahore. These isolates were resistant to ampicillin, cefuroxime and ceftazidime, but were sensitive to carbapenem and aminoglycosides.

title: IMPACT OF SELF-EFFICACY AND ACADEMIC PERFORMANCE IN THE DROPOUT OF HIGHER EDUCATION STUDENTS

description: ABSTRACT Dropping out of Higher Education has implications for students and universities, and the identification of variables associated with dropout makes it possible to develop actions that reduce its occurrence. This study analyzes the direct and mediated impacts of self-efficacy, income, sex, age, receipt of social assistance grants and entry into a preferred option course in evasion. Data were collected from 346 university students through a Socioeconomic Questionnaire, the Self-Efficacy Scale in Higher Education, in addition to documentary information, and were analyzed using the AMOS software. The results identified that being a woman and manifesting high self-efficacy are associated with better academic performance, which are related to lower risks of dropping out. It was also found that being a woman and attending the preferred option course decreases the chances of dropping out. Such results reinforce the weight of personal, psychological, academic and career variables in dropout and suggest ways for interventions that promote student permanence.

title: Living in the city and producing in the countryside: the growth of a new type of farmer and agriculture in Brazil

description: ABSTRACT: Living in rural neighborhoods has always been a characteristic of small and medium-sized Brazilian farmers. However, when observing the agricultural censuses of 2006 and 2017, carried out in Brazil, there is a tendency to separate the place of work and residence of farmers. This articleanalyzed the double residence and the phenomenon of pendular displacement of farmers in the municipalities of Zona da Mata Mineira (ZMM), an important coffee region in Minas in Brazil, and to discuss its possible causes and impacts in the region. The research used data from the 2006 and 2017 Agricultural Censuses of the Brazilian Institute of Geography and Statistics. The data were analyzed using descriptive statistics and multivariate linear regression models in order to better understand the factors that correlate with the percentage of owners living in cities in the municipalities of region. The results showed that, in the case of the ZMM, the growth of urban residence of farmers more expressive than the other regions of the country is mainly due to the predominance of small coffee producers. Furthermore, living in the city does not mean abandoning agricultural establishments, since living in the city does not prevent daily work in the countryside. It was concluded that the urban residence of the farmers constituted a reproductive strategy that made it possible for them to carry out other activities as well as the receipt of retirement and pensions that complement the agricultural income and, consequently, the maintenance of the agricultural establishment.

title: SCHOOL PSYCHOLOGY: DIALOGUE BETWEEN TECHNICAL REFERENCES AND PRACTICE PUBLICATIONS

description: ABSTRACT In this article we discuss the dialogue between the “Technical References for the Performance of Psychologists in Basic Education”, a document published by the Federal Council of Psychology, and the publications of practices in School Psychology, considering the contributions of the scope to the educational processes that produce human development. This study aimed to carry out a systematic literature search between 2009 to 2019 in order to identify what psychologists’ practices have been in the school context and to establish a relationship with the Technical References. The method applied was Systematic Bibliographic Review, using the descriptors: School Psychology, School Psychologist’s Performance and School Psychologist’s Practice. The databases consulted were: SciELO, LILACS and CAPES. We conclude that there are important examples of practices carried out in the context of teaching and learning that can serve as a reference for various interventions and that are consistent with the Technical References.

title: FRACTIONAL ORDER LOG BARRIER INTERIOR POINT ALGORITHM FOR POLYNOMIAL REGRESSION IN THE ℓ p -NORM

description: ABSTRACT Fractional calculus is the branch of mathematics that studies the several possibilities of generalizing the derivative and integral of a function to noninteger order. Recent studies found in literature have confirmed the importance of fractional calculus for minimization problems. However, the study of fractional calculus in interior point methods for solving optimization problems is still new. In this study, inspired in applications of fractional calculus in many fields, was developed the so-called fractional order log barrier interior point algorithm by replacing some integer derivatives for the corresponding fractional ones on the first order optimality conditions of Karush-Kuhn-Tucker to solve polynomial regression models in the ℓ p −norm for 1 &lt; p &lt; 2. Finally, numerical experiments are performed to illustrate the proposed algorithm.

title: Phenolic composition of jussara (Euterpe edulisMartius) from Minas Gerais and Espírito Santo, Brazil, determined by high performance liquid chromatography coupled to diode array detection and electrospray ionization tandem mass spectrometry (HPLC-DAD-ESI-MS)

description: ABSTRACT: This research assessed the phenolic composition of Jussara pulp from the Brazilian states of Minas Gerais (MG) and Espírito Santo (ES) using HPLC-DAD-MS/MS. Seventeen anthocyanins were detected in fruits, derived from cyanidin, pelargonidin and peonidin. Among the non-anthocyanic phenolic compounds, flavonols (kaempferol, quercetin and isorhamnetin derivatives), flavan-3-ols (catechin, epicatechin, B-type procyanidins and unknown dimers) and resveratrol in its glycosylated form have been identified. Catechin (32.41-60.56 mg 100g-1) and epicatechin (18.86-40.92 mg 100g-1) were the main flavan-3-ols present in the fruits. The samples showed small concentrations of resveratrol glycosides (0.02-0.91 mg 100g-1). The analytical methodology used (HPLC-DAD-ESI-MS/MS) permitted the identification of newly reported compounds in this fruit.
