title: Antioxidant effect of cathodic water on seeds

description: ABSTRACT: Recalcitrant and intermediate seeds have limitations regarding conservation because of their sensitivity to desiccation and response to storage. Establishing a method for seed storage is difficult because these seeds deteriorate rapidly, which can intensify production of reactive oxygen species that cause lethal oxidative damage to plant tissues. Orthodox seeds, which have greater tolerance to desiccation and storage, are also subject to deterioration processes, in degrees that vary according to the species. Damage caused by harmful levels of free radicals can be mitigated by the action of endogenous or exogenous antioxidants. Recent studies have led to new technologies for protection coming from antioxidants, one of which is cathodic protection. This is a technique with promising results in recalcitrant species, as well as in other living organisms. This paper reviews results regarding the antioxidant activity of cathodic water produced from electrolysis of a calcium chloride and magnesium chloride solution.

title: Intramuscular fatty acid composition of steers finished on oat pastures mixture with vetch or cornmeal supplementation

description: ABSTRACT: The effects of energetic supplementation and mixture vetch (Vica sativa L.) were studied to evaluate the intramuscular fatty acid profile of steers finished on oat (Avena sativa L.) pastures. Eighteen 21-month-old crossbred steers were evaluated. The experiment was carried out in three treatments and six repetitions: oat pasture (OA), oat pasture + vetch (OA + VET), and oat pasture + supplementation (OA + SUP). Supplementation comprised the addition of corn meal at a daily dose of 1% of the animals’ body weight. Steers receiving supplementation had higher lipid content in Longissimus lumborum than did those fed with OA + VET (1.25 vs 1.02%), whereas those fed with OA (1.15%) showed intermediate values. Conjugated linoleic acid levels were higher in steers fed OA (0.57%) and OA + SUP (0.59%), whereas the highest amount of omega-3 fatty acids was observed in animals fed OA + VET (3.32%). Pasture-finishing without supplementation resulted in a lower ratio of n-6:n-3 (3.14). Steers finished in oat mixture with vetch showed healthier intramuscular fat than did those finished with cornmeal supplementation; importantly, the higher the amount of PUFAs, the better n-6:n-3 ratio.

title: Vesicular stomatitis due to Indiana III (Alagoas/VSIV-3) is endemic in Brazilian state of Ceará

description: ABSTRACT: Although Northeast Brazil is considered free of foot and mouth disease (FMD) with vaccination, several economic and health damages are still recorded due to the occurrence of vesicular syndromes that can be evaluated, such as Vesicular Stomatitis (VS). Therefore, this study aimed to confirm the occurrence of this disease and to determine the predominant viral serotype in suspected cases notified to the Official Veterinary Service of Ceará in 2013 performing official diagnostic protocols recommended by the World Organization for Animal Health. After clinical and epidemiological investigation in 46 farms, 32 probable cases of VS were considered with 78 sampled animals, 65 bovines and 13 equines. Serum (54) and epithelium (24) samples were collected. Six (14.6%) of 41 bovines and 8 (61.5%) of 13 equines described seroconversion to Indiana Vesiculovirus (IVV) by viral neutralization. The IVV was detected in 15 (62.5%) of 24 bovines epithelia using the indirect sandwich ELISA. Finally, positive epithelium underwent complement fixation test viral subtyping that identified the occurrence of Indiana III serotype (Alagoas/IVV-3) in 11 (73.3%) of 15 previous positives cattle. These were the first confirmed cases of VS in Ceará with an official diagnosis of IVV-3, confirming the endemic character attributed to the state through previous unofficial serological surveys. The presence of VS is a continuing diagnostic challenge, given the risk of possible incursions of FMD. Vesicular stomatitis is recurrent and is a worrying in this area free of foot and mouth disease with vaccination that bring damage to producers and a maximum alert to the Sanitary Defense Organs in the face of a probable case of vesicular syndrome.

title: Antifungal activity and inhibition of aflatoxins production by Zingiber officinale Roscoe essential oil against Aspergillus flavus in stored maize grains

description: ABSTRACT: Essential oils are possible alternatives to the use of synthetic pesticides for control of fungal contamination. Ginger (Zingiber officinale) essential oil (GEO) is known for having antifungal and antiaflatoxigenic properties, but its use as a fumigant in situ has not been studied yet. The aim of this study was to evaluate GEO’s effects upon Aspergillus flavus as a fumigant agent in stored maize grains. The main compounds reported in GEO were α-zingiberene (23.85%) and geranial (14.16%), characterized by gas chromatography-mass spectrometry and nuclear magnetic resonance. The GEO was used as a fumigant in irradiated maize grains in concentrations ranging from 5 to 50 µg/g and the resulting effects were compared to a synthetic antifungal agent (carbendazim and thiram), an antifungal traditionally used for seed treatment. The antifungal efficacy of GEO against A. flavus has been proven in a dose-dependent manner through in situ (maize grains) test. The GEO inhibited aflatoxin production at concentrations 25 and 50 µg/g and controlled fungal growth. Therefore, GEO can be used as an effective and non-toxic alternative to conventional treatments in stored maize grains for the natural control of A. flavus.

title: Rooting competence of mini-cuttings of Cabralea canjerana clones in different seasons

description: ABSTRACT: The objectives of this research were to evaluate the rooting competence of mini-cuttings throughout the four seasons and to estimate the adventitious rooting time of canjerana clones. A clonal mini-garden was established with 11 clones in a closed hydroponic system. Evaluations were performed throughout the four seasons for the number of mini-cuttings produced per mini-stump, percentage of survival and rooting of mini-cuttings, number of roots, average root length, and number of rooted mini-cuttings per mini-stump. Data were submitted to analysis of variance and means were compared. A rooting curve was estimated for clones 10SM05, 12SMI25, and 12SMI43 that exhibited high competence for adventitious rooting. Our results indicated that canjerana clones can be selected for adventitious rooting competence of mini-cuttings during different seasons, and that canjerana mini-cuttings should be cultivated for 63 days in a rooting chamber.

title: Morphological and physiological variation in Toona ciliata under water and salinity stress

description: ABSTRACT: The objective of this paper was to test the effects of water deficit, saturation and salinity in individuals of Toona ciliata. Seven treatments were tested: the control group, the complete suspension of irrigation, the permanent saturation of the pot soil and four doses of NaCl (50, 100, 200 and 400 µmol). The experimental design was completely randomized, with 8 repetitions in each treatment. Physiologic evaluations were carried out during the experiment, and morphologic evaluations at the end. The plants were responsive to the applied stresses comparatively to the control group. Reductions were observed in morphological and physiological variables in all treatments under stress. All individuals under stress recovered slightly in the end of the experiment, and began to sprout again, representing a probable adaptation to the conditions.

title: Health-related factors on tobacco consumption in Turkey

description: ABSTRACT: In this study, we analyzed the role of individuals’ health-related factors along with socio-demographic and economic characteristics on both the likelihood of tobacco consumption and quantity demanded levels using two competitive econometric methods: double hurdle model versus hyperbolic sine double-hurdle model. Statistical tests confirmed the dependency errors between the prevalence rate of smoking and the consumption level, whilst the inverse-hyperbolic sine double-hurdle model data fits best in describing the normalization of the data and the two data generating processes: the probability and consumption levels of cigarettes. Also, the variance-covariance of the selected model as a function of additional exogenous variables are confirmed, while the error terms between the likelihood to smoke and the consumption levels are positive and statistically significant, indicating that holding control variables fixed, the uncontrolled variables out of the system that increase the prevalence rate of smoking also boost the consumption level, or vice versa. Many individual disease variables are significant in both equations, breaking new grounds in literature for identifying how both the prevalence rate of smoking and amount have shaped.

title: Consumer preferences toward organic food and the moderating role of knowledge: a case of Pakistan and Malaysia

description: ABSTRACT: The present study aimed to identify the elements of the Theory of Planned Behaviour along with health consciousness and determine the role of knowledge as a moderating variable in Pakistan and Malaysia. Three hundred and forty-one observations from Pakistan and 280 observations from Malaysia were acquired through questionnaire; while, confirmatory factor analysis and structural equation modelling was applied for the analysis. The magnitude of the results varied across both countries; however, attitude, subjective norms and health consciousness, as well as their interaction terms, were significant predictors, whereas, perceived behavioural control and its knowledge interaction terms had insignificant impacts on the purchase intentions of consumers for both countries. This research will help to further understand about consumer perception in the purchase of organic food items, which will assist retailers, advertisers and manufacturers in developing strategies for such products.

title: How different soil moisture levels affect the microbial activity

description: ABSTRACT: The lowland soils are characterized by high susceptibility to water saturation. This anaerobic condition is usually reported in paddy fields and alters the decomposition process of soil organic compounds. The aim of this study was to evaluate the soil microbial and enzymatic activity of a lowland soil at different soil moisture contents. A poorly drained Albaqualf cultivated with irrigated rice was used to evaluate microbial and enzymatic activity in treatments with different levels of soil moisture, being: i) 60% of field capacity (FC) (60�); ii) 100% of FC (100�); iii) flooded soil with a 2 cm water layer above soil surface, and iv) soil kept at 60� with late flood after 29 days the incubation. The greater soil microbial activity was observed in the 100� treatment, being 41% greater than 60� treatment and only 2% higher than flooded treatment. The enzymatic activity data by fluorescein diacetate (FDA) hydrolysis corroborated the higher CO2 release in treatments with higher soil moisture content. Differently from the results reported, the main methodologies to evaluate microbial activity still recommend maintenance of the soil with a moisture content close to 60% of the FC. However, in lowland soil with history of frequent paddy fields, the maintenance of moisture close to 60% of the FC can limit the microbial activity. The soil respiration technique can be used to evaluate the microbial activity in flooded soil conditions. However, further studies should be conducted to understand the effect of the cultivation history on the microbial community of these environments.

title: Fuzzy modeling of volumetric efficiency and specific energy consumption in agricultural screw conveyors

description: ABSTRACT: Vertical screw conveyors have low energy efficiency but this is generally acceptable within the normally low power range. Previously, a fuzzy logic approach was used to model volumetric efficiency and specific energy consumption in screw conveyors. The performance of conveyors in different working conditions and the geometry of the screw were studied. It was reported that increasing the screw speed, pitch, and loading angle also increases specific energy consumption. In this study, an intelligent fuzzy model based on the Mamdani approach was developed to predict volumetric efficiency and specific energy consumption. The model inputs included the slope, speed, and pitch of screw conveyors. The fuzzy model consists of 27 rules in which three parameters, namely the goodness of fit (η), relative error (ε), and coefficient of correlation (R), are used to evaluate the model. The goodness of fit, relative error, and coefficient of correlation values were 0.986, 5.28%, and 0.99, respectively, for volumetric efficiency and 0.987, 4.93%, and 0.99, respectively, for specific energy consumption. Results revealed that the developed model is capable of predicting volumetric efficiency and specific energy consumption in barley transport under different working conditions with high accuracy.

title: Ecotoxicity test as an aid in the determination of copper guideline values in soils

description: ABSTRACT: The process of identifying a contaminated area involves a preliminary assessment consisting of chemical analysis and comparison with guideline values. In Brazil, these values are included in the CONAMA Resolution no. 420/2009, based on chemical analysis and phytotoxicity. The objective of this research was to evaluate the ecotoxicity of copper in two natural soils in the state of Rio de Janeiro, a Haplic Planosol (sandy) and a Red-Yellow Argisol (medium texture), to verify if the values established by the legislation offer protection to the soil fauna. Lethality and reproduction tests were performed with Eisenia andrei worms and Folsomia candida springtails. Results indicated copper values in Planosol as LC50 435 mg kg 1 and EC50 29 mg kg 1 for E. Andrei and LC10 137 mg kg 1 and EC50 117 mg kg 1 for F. candida. In Argisol, these results were LC50 690 mg kg 1 and EC50 61 mg kg 1 for E. andrei, and LC10 42 mg kg 1 and EC50 138 mg kg 1 for F. candida. Values reported are lower than the research value (200 mg kg-1) established by the CONAMA resolution 420/09, indicating that concentrations lower than the limit values may affect these organisms, depending on the type of soil. Worms were more sensitive than springtails to copper contamination, and sandy soil was more susceptible to ecotoxicity due to copper contamination, probably due to the greater bioavailability of the metal. Results of such ecotoxicity tests should be considered in the development of soil guideline values.

title: Seeding furrow opening mechanisms and the soybean planting in lowland areas

description: ABSTRACT: The objective of this research was to evaluate the effect of seeder furrow opening mechanisms on soil physical characteristics, plant growth, and soybean yield in lowland areas with the presence of compacted layer near the surface. An experiment was conducted in the lowland experimental area of the Federal University of Santa Maria-RS, Brazil, during the 2015/16 and 2016/17 growing season. The experimental design was a randomized block with five replications and four treatments: Planter using shank (S) at 0.23 m depth; S at 0.13 m; Planter using double disk at 0.07 m depth and Raised-bed + S at 0.12 m depth. The use of S at 0.23 m depth allowed reduction of penetration resistance and increase of soil macroporosity in the layers 0-0.1 and 0.1-0.2 m depth in the seeding row. Sowing with S at 0.23 m depth and Raised-bed + S at 0.12 m depth allowed a better development of soybean plants in compacted irrigated rice area (higher nodulation, leaf area index and root growth), as well as higher grain yield.

title: Intergenerational financial transfers and physical health of old people in rural China: evidence from CHARLS data

description: ABSTRACT: With the reduction of intergenerational temporal transfers, financial transfers from adult offspring to their elderly parents are prevailing in rural China. Although much has been done, little is known about the association between the expansion of intergenerational transfers and rural old people’s physical health in China. The purpose of this paper was to examine the effect of intergenerational financial transfers on the elders’ physical health in rural China. Using data collected from China Health and Retirement Longitudinal Study (CHARLS), panel data fixed effect model and threshold model are employed to estimate the impact of intergenerational financial transfers on the old people’s physical health in rural areas. Results showed that; although, the intergenerational financial transfers have a positive effect on the old people’s physical health, no linear relationship exists between them. Intergenerational financial transfers are clearly less effective for low-income old people’s physical health than those of middle-income, while the effect on high-income old people’s health is the most insignificant. Studies concerning the effect of intergenerational financial transfers on the elders’ health in developing countries remain limited. Findings of this paper provided great insights into how intergenerational transfers, such as intergenerational financial transfers, may affect the well-beings of old residents in rural areas. Additionally, this study can offer inspiration to policy makers regarding what measures they should take to enhance rural old residents’ well-beings.

title: From the relationship with knowledge to identities of physical education: narratives of students in the High School

description: Abstract It aims to understand the relationships that students establish with the knowledge in the classes of physical education and its implications for the constitution of the identities of this curricular component. It analyzes the autobiographical narratives of students of the 3rd year of High School on the different ways of appropriating their schooling process with physical education. Uses oral and imagery narratives of students as sources. The results showed that the relationship with the knowledge and the identities of physical education produced are strained by the school logic and the experiences, which results in the loss of their interest in the classes during the schooling process.

title: The use of cognitive instruments for research in early childhood education: constraints and possibilities in the Brazilian context

description: Abstract This paper discusses the adaptation of the iPIPS assessment for use in research with Brazilian children between the ages of four and seven. It debates the importance of having a baseline measure to assess early childhood education policy as well as the advantages of collecting high-quality information about children’s development. Not knowing how children are progressing could harm disadvantaged children and increase school inequality. The data used in the analysis was based on the pre-test of the iPIPS 2016 for mathematics and language in a total of 560 cases collected in three Brazilian cities. The preliminary analyses indicate that the items of both tests present adequate behavior, suggesting the theoretical adequacy of the items and a good adaptation and application protocol.

title: German primers from the Rotermund publishing house (1927-1933): gender representations in rural work

description: Abstract This academic paper aims to analyze gender representation, especially concerning the work roles attributed to men and women presented in the illustrations of the guidelines Mein Rechenbuch (My calculus book) and Fibel für Deutsche Schulen in Brasilien (Guidelines for German schools in Brazil), both produced by the publishing house Rotermund, which was linked to the Rio-Grandense Synod. Elaborated in German language, these guidelines sought to attend Synod schools linked to Lutheran churches, which worked alongside the colonies of German-Pomeranian immigrants in southern Rio Grande do Sul. In the course of this study, the aim was to identify possible social directions transmitted through the work organization illustrated in the guidelines. In this context, it was observed that social relations represented are ethnic and cultural constructions historically established, integrating a process that involves school and religious institutions.

title: The option for schooling in university secondary schools in Argentina: school choice between glass ceilings and social closure

description: Abstract This article revisit the debates about school choice focusing on a group of university high schools in the capital of the Province of Buenos Aires, Argentina. From exploring the sociocultural composition of school fees, we are known to families who attend these prestigious schools and revise discussions on school choice regarding processes of social closure that persist beyond they are state high schools that have a public and open lottery as a method of admission. The methodological approach started from a multiple case study involving the combination of quantitative and qualitative data collection methodologies. Between 2012 and 2016 they were made observations, interviewed in depth 13 central actors to the institutions, made 67 structured interviews to teachers selected randomly and recovered a corpus composed of six institutional documents included information on sociodemographic chips of the students. It is concluded that it is the middle sectors that colonize this fragment of schools.

title: Interferences in the class: teachers’ dynamic and perceptions

description: Abstract Instances of school institutions directly intervene on the public schools (state and municipal) in the city of São Paulo. There is a “dynamic of interferences”: a set of frequent and direct interventions in the class, normally connected to the enactment of educational policies. This accumulation of projects in the schools lead to constant interruptions in teachers’ work. We have researched its consequences on teachers and school education, based on the analysis of official texts and teachers’ statements. We have found that, though such policies are supported by a discourse of quality in education, according to the teachers the dynamic of interferences hinders teachers’ work and, possibly, school education.
