title: Reduction emission of particulate matter as a function of insertion of biodiesel mixtures from soybean and castor bean in diesel

description: ABSTRACT Environmental and economic concerns resulting from demand for fossil fuels corroborate the need for alternatives to reduce environmental and economic impacts arising from the increasing use of diesel-powered vehicles and machines. The diversification of raw materials used to produce biodiesel can allow the improvement of fuel quality and of emissions resulting from their use in engines. This study evaluated the emission of particulate matter (PM) using biodiesel from soybean and castor bean in diesel/biodiesel mixtures, as well as its viscosity and oxidation stability (prerequisites for quality). For this purpose, biodiesel with different proportions of soybean and castor bean (SyMx) were evaluated, where y and x represent soybean and castor bean biodiesel percentages, respectively: S100M0, S75M25, S50M50, S25M75 and S0M100, mixed with diesel (BX), in the following percentages: 7 (diesel B7), 25 (B25), 40 (B40), 50 (B50), 75 (B75) and 100% (B100). The smoke opacity, viscosity and oxidation stability were determined according to NBR 13037, NBR 10441 and EN 14112, respectively. Among the analyzed mixtures, the commercial diesel (B7) emitted higher amounts of PM, whereas other mixtures, which met the prerequisites for quality (B25 and B40), emitted smaller amounts of PM as increased castor bean biodiesel percentage in mixtures SyMx, as well as with the increase of biodiesel in the mixtures BX. They were also achieved gains in quality as a function of the different compositions SyMx.

title: A New Route to Synthesize MnSe Thin Films by Chemical Bath Deposition Method

description: Manganese selenide (MnSe) crystalline thin film was produced with chemical bath deposition on substrates (commercial glass). Transmittance, absorption, optical band gap and refractive index were investigated by UV/VIS spectrum. The hexagonal form was observed in the structural properties in XRD. The structural and optical properties of the MnSe thin films were analyzed at different pHs. SEM and EDX analysis were used for the surface analysis in the films. The films had the best crystalline at pH: 9. At pHs of 11 and 10 the MnSeO4 structure was observed. The films with the lowest film thickness were found in baths prepared with pH: 11. The highest refractive index was observed in films produced with a pH of 10 at a film density of 1.96. The grain size of MnSe thin films has a higher value at pH: 9.

title: Pharmaceuticals oxidation by chlorine and byproducts formation in aqueous matrices in bench scale

description: ABSTRACT Pharmaceuticals and endocrine disrupting compounds are found in Brazilian natural waters, including some water sources for public supply, also due to the low coverage of sewage collection and treatment in Brazil. This study investigated the removal of three pharmaceutical compounds - sulfamethoxazole (SMX), diclofenac (DCF) and 17β-estradiol (E2) - from aqueous solutions by means of chlorine oxidation (sodium hypochlorite) by varying the dose of chlorine and contact time in batch tests. The chlorine solutions were examined by chromatography attached to the mass spectrometry in order to identify the oxidation by-products. For 10 min contact time, mean removal values of 61% were observed for DCF; 36% for E2; and 33% for SMX, when the chlorine dose was 1.5 mg L-1. Just for DCF there was a statistically significant difference (α=0.05) in the removal efficiency when increasing the chlorine dose to 3.0 mg.L-1. The oxidation followed the kinetic model of pseudo-second order, with k2 values of 0.0168 L.µg.min-1 for SMX (at both chlorine doses tested); 0.0133 and 0.0798 L.µg.min-1 to DCF; and 0.0326 and 0.0289 L.µg.min-1 to the E2 at chlorine doses of 1.5 and 3.0 mg L-1, respectively. Finally, it was verified that an increase of the contact time favored the oxidation of all pharmaceuticals tested, although with the perspective of by-products formation for SMX and E2.

title: Energy balance of irrigated maize silage

description: ABSTRACT: The aim of the present study is to evaluate the energy balance and energy efficiency of the silage maize crop in the Center for Research, Development and Technology Transfer of the Universidade Federal de Lavras (CDTT-UFLA). The crop was irrigated by center pivot and the stages of maize cultivation and energy inputs were monitored for the 1st and 2nd crops of the 2014/2015 harvest. Results from the energy analysis showed the crop had a total energy input of 45,643.85 MJ ha-1 and 47,303.60 MJ ha-1 for the 1st and 2nd crops and a significant predominance of direct energy type (about 92% of the matrix). Regarding direct energy inputs, the diesel oil was the most representative, contributing with approximately 38% of the total energy demand. Conversely, the irrigation system contribute with 3.92% e 5.97% in the 1st and 2nd crops, representing the largest indirect energy input. Nevertheless, irrigation and crop management allowed the system achieving high levels of productivity, resulting in an energy efficiency of 25.1 and 28.1 for the first and second crops respectively.

title: The Flora of Paraíba State, Brazil: subfamilies Ajugoideae and Viticoideae (Lamiaceae)

description: Abstract: The Lamiaceae family includes about 7,000 species allocated in 236 genera, with almost cosmopolitan distribution, currently divided into nine subfamilies. In Brazil 46 genera and 525 species occur, distributed in four subfamilies. Among these subfamilies, Ajugoideae and Viticoideae were originally parts of the Verbenaceae family, being transferred to Lamiaceae as a result of several systematic studies on the two families. Ajugoideae is characterized by having drupes with four mericarps, non-persistent styles and pollen grains with exine formed by granular and branched columns. On the other hand, Viticoideae is characterized to have drupes with 4-locular pyrenes or 2 2-locular pyrenes and exine microreticulate or slightly rough. We present here the results of a taxonomic survey of the subfamilies Ajugoideae and Viticoideae (Lamiaceae) for Paraíba State, Brazil, based on excursions to collect fertile material, analyses of specimens incorporated into herbaria in Paraíba (ACAM, CSTR, EAN and JPB) and Pernambuco State (IPA and PEUFR), and consultations of the SpeciesLink and Herbário Virtual REFLORA databases. Identifications were based on the specialized literature and the examination of type and protolog specimens. Ten species belonging to three genera, five belonging to the subfamily Ajugoideae (Aegiphila integrifolia (Jacq.) Moldenke, A. luschnathii Schauer, A. pernambucensis Moldenke, A. verticillata Vell. and Amasonia campestris (Aubl.) Moldenke) and five to the subfamily Viticoideae (Vitex gardneriana Schauer, V. megapotamica (Spreng.) Moldenke, V. orinocensis Kunth, V. rufescens A. Juss. and V. schaueriana Moldenke) were recorded. The taxonomic treatment includes a key to identify genera and species, descriptions, illustrations, taxonomic comments, geographic distribution, habitats and phenological data of the species.

title: Desmatamento, degradação e violência no "Mosaico Gurupi" - A região mais ameaçada da Amazônia

description: Abstract The "Gurupi Mosaic" is located between west Maranhão and east Pará states, in the Belém Endemism Area, which although being the most deforested region of the Amazonian biome in Brazil, preserves superlative biological and cultural diversity. The Mosaic includes six indigenous lands (Alto Turiaçu, Awá, Caru, Araribóia, Rio Pindaré, Alto Rio Guamá) and a conservation unit (Gurupi Biological Reserve). These protected areas conserve the region’s main forest remnants and guarantee the maintenance of essential ecosystem services. However, this region is under constant threats of deforestation and degradation by illegal logging and arson. Indigenous peoples living in the region are victims of the violence associated with such crimes. To promote the conservation and restoration of these areas, several indigenous and non-indigenous institutions have been working together to formalize the "Gurupi Mosaic" with the Ministry of the Environment. The proposal presented here includes the Mosaic and one ecological corridor in the state of Maranhão, which will connect the region’s last forest remnants through the restoration of the riparian forests along the main rivers. The conformation of the Mosaic aims to integrate efforts to protect territories, restore forests and strengthen indigenous culture and education. This could turn the most threatened region of Amazonia into an example of conservation and economic and social sustainability.

title: Effect of melatonin on antioxidant capacity, ınflammation and apoptotic cell death in lung tissue of diabetic rats

description: Abstract Purpose: To investigate the effects of melatonin on antioxidant capacity, inflammation and apoptotic cell death (through expression of cleaved-caspase 3) in lung tissue samples of diabetic rats. Methods: Thirty male Sprague-Dawley rats were randomly divided into three groups. Group 1 (control group) was made up of healthy rats. Group 2 (diabetes group) received streptozotocin at a dose of 50 mg/kg/day for 5 days.Group 3 (diabetes plus melatonin group) received streptozotocin at a dose of 50 mg/kg/day for 5 days and then they received melatonin at a dose of 20 mg/kg/day between 28thand 35thdays of the study. Results: Tissue MDA and MPO levels were found to be significantly higher in diabetes group compared to control group (p&lt;0.05) whilst administration of melatonin was found to significantly lower this increase down to normal levels (p&lt;0.05). Bronchus associated lymphoid tissue (BALT) was more severe in diabetics whereas administration of melatonin alleviated this hyperplasia. Cleaved caspase 3 activity was severe in hyperplastic BALT in diabetic rats however in lowered down to moderate level when melatonin was administered. Conclusion: The melatonin caused an increase in antioxidant capacity and decreased the expression of cleaved-caspase 3.
