title: A proposed index to assess quality of waters from desalination plants

description: ABSTRACT Reverse osmosis is the technology commonly used to produce fresh water from brackish groundwater. Due to the reject brine generated in desalination plants by reverse osmosis, vulnerability assessment to define critical areas to monitor waters from desalination has been an important tool for delineating the monitoring networks required for surveillance of potential salinization sites. The objective of this study was to assess the quality of waters sampled in desalination plants by a quality index, which provides a relative assessment of water vulnerability to potential salinization. The present study proposes an index to assess the quality of waters from desalination plants initially using the chemical parameters electrical conductivity, sodium adsorption ratio, Mg2+/Ca2+ ratio, and the ions sodium, chloride and bicarbonate. The index to assess quality of waters from desalination plants showed good performance and can include additional parameters referring to the soil and crop exploited. High values of the relative index of quality of waters from desalination plants are considered as possible indicators of risk of soil salinization and groundwater contamination. The highest level of land use impact on the quality of waters from desalination plants was found in reject brine samples followed by well water samples.

title: Factors that Influence the Production, Environment, and Welfare of Broiler Chicken: A Systematic Review

description: ABSTRACT The objective of the present study was to characterize the scientific production regarding the factors that influence broiler chicken production, and that were published from 2000 to 2015 in journals indexed in the database of Google Scholar, Scielo, and ScienceDirect. The research was done in the Thermal Comfort Laboratory at FEAGRI- UNICAMP, and the concept of the systematic review was applied. The research criterion was initially defined (the keywords) aiming to identify and evaluate the variables that describe the experimental characteristics and the animals. The primary keywords identified were: broiler chicken from commercial strains, broiler production, rearing conditions, thermal environment, air quality, acoustic environment, light intensity, management, and heat stress. Those were the key words searched in the database of the online libraries. The selected articles were registered into an electronic spreadsheet with the title, the name of the authors, year of publication, language, the journal where it was published, the keyword, the period when the research was done, source/ database, and the abstract. A total of 167 articles were selected, and only 34 were added to the review. The use of the systematic review of the literature allowed identifying the main variables that positively influence the broiler performance, such as the temperature near the thermal comfort, the use of roof lining, besides the use of adiabatic cooling and cast bricks in the laterals. The presence of positive ventilation, as well as the use of yellow curtains and constant lighting, has also influenced a better performance to broilers.

title: Between childhood and dreaming: Guna pedagogy of autonomy (Panama)

description: Abstract This article addresses children’s process of growing and the social production of autonomy among the Guna (“Kuna”), people who traditionally inhabit the archipelago of San Blás, in the eastern portion of the Atlantic coast of Panama. My goal is to emphasize dreaming as a personal experience that serves as a context or “frame” for pedagogical practice. Considering the processes of learning during childhood, as well as the Amerindian classical discussion of rhetoric and power, I argue that Guna social philosophy establishes a sophisticated correlation between the dominant cultural discourse and the possibility of escaping it. It expresses the ideal of shared life (bulagwa iddoged, “feeling together”) while emphasizing personal autonomy as the means to realize it. This ambivalence was well expressed by Atencio López, Guna intellectual and activist who told me: “The world spins in the same and different way for everybody.”

title: Drying kinetics of baru flours as function of temperature

description: ABSTRACT Several types of seeds have been initially used in the food industry due to the great potential that vegetable proteins have. Baru is a fruit commonly found in the Cerrado biome, having a high nutritional value. This paper aimed to determine and analyze the drying kinetics of whole and defatted baru almond flours at different temperatures. The flour resulting from almond milling was defatted using petroleum ether. The drying processes were performed at temperatures of 40, 50 and 60 ºC. The mathematical models of Page, Henderson and Pabis, Midilli & Kucuk, Thompson and Approximation of Diffusion were fitted to the experimental data. The results showed a noticeable effect of air temperature on the drying kinetics of whole and defatted baru almond flours. According to the statistical parameters of analysis, the models Midilli & Kucuk and Page were the ones with the best fits to the experimental data. The effective diffusivity values found ranged from 8.02 × 10–10 to 19.90 × 10–10 m2 s-1 and for the activation energy were 22.39 and 39.37 KJ mol-1 for whole and defatted almonds, respectively.

title: PERMEABILITY OF THE STATE TO PRIVATE ACTORS IN THE PROVISION OF EARLY CHILDHOOD EDUCATION: WHAT MUNICIPAL PLANS SAY (2014-2024)?

description: ABSTRACT In this article we present the results of a research that sought to map the trends concerning the ways of supplying early childhood education, in the childcare stage, described in Municipal Education Plans, either formulated and/or reformulated in 2015 under the determination of Article 8, Law 13005/2014, which establishes the National Education Plan for the period from 2014 to 2024, as well as possible clarifying factors for the offer modality. The municipalities were selected through stratified random sampling. The research made use of techniques of descriptive statistics, content analysis and chi-square test to analyze the gathered data. The elements resulting from the study point out to the dispersion of the offer to actors located outside the state apparatus, allowing the statement that this reasoning tends to be a permanent policy in the country, with possible different effects on the education, reliant on the legal nature of the partner entity, since it is specified in Plans of State, not of government.

title: Essential oils from Piper aduncum inflorescences and leaves: chemical composition and antifungal activity against Sclerotinia sclerotiorum

description: Abstract Even though essential oils from Piper aduncum (Piperaceae) have different biological activities, little is known about their application to agricultural areas. White mold is a plant disease caused by the phytopathogen Sclerotinia sclerotiorum, which needs to be controlled by alternative measures. This study aimed at evaluating the effect of essential oils from P. aduncum leaves (PL-EO) and inflorescences (PI-EO) on the mycelial growth of S. sclerotiorum. Essential oils from P. aduncum were obtained by hydrodistillation by a Clevenger-type apparatus while their chemical composition was analyzed by GC-MS and GC-FID. Piperitone (23.4 %), myristicin (12.4 %), terpinen-4-ol (12.3 %), β-caryophyllene (7.2 %), α-humulene (6.9 %), germacrene-D (6.9 %) and dillapiol (6.3 %) were the main constituents found in oils from P. aduncum. The in vitro antifungal activity showed that PI-EO dose above 30 µL inhibited mycelial growth in 100 %, whereas PL-EO at 50 µL inhibited it in 98.74 %. This is the first report of the chemical composition of PI-EO and results suggest that the essential oils under evaluation have high potential to control the phytopathogenic fungus S. sclerotiorum.

title: Improvement of nutritional and physicochemical proprieties of milk chocolates enriched with kale (Brassica olereacea var. acephala) and grape (Vitis vinífera)

description: Abstract Consumption of functional food has been growing recently, and products with healthier ingredients can influence the purchasing decisions. Studies have been shown that the development of chocolates with addition of functional ingredients can improve its nutritional properties. Considering it, the present study demonstrated that the addition of lyophilized kale and grape can modify physical, nutritional and physicochemical characteristics of the chocolates. The enriched milk chocolates showed higher values of dietary fibers and mineral content, which improved nutritional quality of the product when compared to plain milk chocolates. The results of the HPLC-DAD suggested the transference of phenolic compounds of kale and grape to the final enriched chocolates. The sensorial analysis indicated that differences among the formulated chocolates were indeed perceived and were well accepted. Thus, the addition of kale and grape in chocolates may be an alternative to improve the nutritional characteristics and the polyphenolic compound content in these chocolates.

title: Thermodynamic properties of Buriti (Mauritia flexuosa) tree gum

description: Abstract Moisture adsorption and desorption isotherms from buriti tree gum (BG) were obtained at different temperatures (25 to 55 °C) in a water activity range of 0.1 to 0.9. The isotherms were classified as type II. The hysteresis loop and moisture of the monolayer decreased as temperature increased and Halsey’s equation proved able to predict with good precision the product’s sorption isotherms in the conditions studied. BG’s isosteric heats of moisture adsorption and desorption were close to the latent heat of vaporization of pure water for moisture levels above 30 g/100 g db and exponentially increased below that level. The enthalpy-entropy compensation theory and the isokinetic relationship were applied and indicated that BG’s moisture adsorption and desorption processes are spontaneous. The integral sorption properties indicated that the increase in surface tension at BG’s moisture sorption sites was more representative for the desorption process.

title: Physicochemical characterization and behavior of biocompounds of caja-manga fruit (Spondias mombin L.)

description: Abstract The aim of this study was to evaluate the physicochemical changes and the antioxidant potential of caja-manga (Spondias mombin L.) fruit during its physiological development. The cycle comprised a period of 260 days after anthesis (DAA), set when the fruits were yellow-orange colored and easily detached from the pads. The results showed that the fruits had simple sigmoid type of growth pattern, with significant increase in mass, and longitudinal and transverse diameters up to 220 DAA. A decrease in total pectins and an increase in soluble pectins, lower acidity and chlorophyll levels, and masking of carotenoids exposure was observed, leading to color changes and softening in fruit. Significant changes were observed from 200 to 220 DAA, which may be the period that fruit has reached its maturity, emphasizing phenolic, vitamin C and antioxidant activity.

title: Simulation of a surface spill of different diesel/biodiesel mixtures in an ultisol, using natural attenuation and bioaugmentation/biostimulation

description: Abstract Accidents caused by leaks and/or spills on soils need to be addressed. Natural attenuation, biostimulation and bioaugmentation can be useful bioremediation strategies for decontamination processes in soils of diesel/biodiesel mixtures. The purpose of this study was to evaluate the degradation rate of the different fuels (B0, B20 and B100) in an ultisol under natural attenuation and biostimulation/bioaugmentation during 60 days of incubation in a controlled microcosm simulating a surface spill over soil. The degradation of different diesel/biodiesel mixtures was monitored for up to 60 days by dehydrogenase activity, respirometry by CO2 release, the most probable number of heterotrophic and degrading microorganism and gas chromatography. The bacterial inoculum employed for biostimulation/bioaugmentation strategy consisted of Bacillus megaterium, Bacillus pumilus, Pseudomonas aeruginosa, and Stenotrophomonas maltophilia. The two bioremediation strategies have showed great degradation rates. The natural attenuation was effective for B0 and B20 treatments. The addition of the bacterial consortium and macronutrients contributed to the increased degradation of pure biodiesel in relation to natural attenuation, with higher rates for CO2 release, enzymatic and degrading activity. It is suggested that the bacterial consortium has proven effective for presenting significant values for such parameters until the end of the 60-day incubation period.
