title: Use of indicators in urban solid waste management: a methodological proposal of construction and analysis for cities and regions: application of the model

description: ABSTRACT This study aimed to evaluate the management of urban solid waste through the application of the management model of sustainable urban solid waste (MGRSUS) developed and implemented in municipalities that make up the metropolitan area of Campina Grande. The model is composed of 46 indicators, 15 categories of analysis and four dimensions and structured by primary and secondary data. In order to obtain those data, semi-structured interviews and on-site visits occurred, in addition to literature and documentary search. Based on those data, it was found out that the smaller municipalities have greater problems in waste management, which can be related to the fact they do not have a technical team to deliver the services, reflecting directly over the urban environmental quality. So, the MGRSUS was considered satisfactory for the purposes for which it is proposed, taking into account it was possible to give an overview of the management of each municipality, enabling the targeting of specific actions for each identified gap.

title: Polystyrene and cornstarch anti-corrosive coatings on steel

description: Abstract This work aims to evaluate the performance of anticorrosive thermoplastic coatings in cold rolled steel sheets. Two types of thermoplastic coatings were studied: polystyrene (PS) and cornstarch. These types of coatings are applied for protection against corrosion during transport and storage of steel plates after cold rolling until delivery to stamping or other processing. The good performance for these coatings is suitably standardized to ABNT NBR 5915-2: 2013 and ASTM A1008 / A1008M-2016. According to corrosion tests carried out in saline chamber, the coatings were satisfactory in different degrees of guarantee of corrosion protection on ASTM 1080 steel, in accordance with standards mentioned.

title: Corporate sustainability and value creation: the case of the “Dow Jones Sustainability Index”

description: Abstract Choosing an enterprise that will be part of Dow Jones Sustainability Index (DJSI) raises some expectations concerning this conquest benefits. We hope that the investment on sustainable development and the inclusion of the company in this select group bring economic and strategic benefits that can reflect in the company market valorization. However, the correlation between social, environmental and financial development is quite complex. In this context, this paper aims to verify whether the inclusion of an enterprise in DSJI list, which presupposes a high social and environmental performance, provides it with greater financial return. We use the case study method in order to investigate the existence of abnormal returns when disclosing the information of the company inclusion in the list, as well to analyze the hypothesis that market has positive expectations concerning to DSJI participation. This study included one hundred and fifty-four companies listed in DSJI that trade their shares on the New York Stock. The results show no effect and do not confirm the greater return hypothesis, but neither do they indicate a reduction in financial performance associated do this fact.

title: Effect of application parameters in Ni-Cr-B-Fe-Si coatings obtained by flame spray

description: ABSTRACT Surface damage of components in service is an issue of great industrial interest because of the costs associated to the replacement of certain critical components. There are several techniques to generate coatings, which provide increased resistance to a particular type of surface damage. In this way, it is achieved surface protection to different solicitation such as temperature, abrasion, erosion, corrosion, etc., obtaining an extension of the useful life. Thermal spray techniques are used today for the production of coatings with thicknesses between 100 and 2000 microns. One of the most commonly used because of its simplicity and low cost is the Flame Spray (FS). The projection parameters and refusion conditions can significantly affect the characteristics of the obtained coating. Nickel base alloys are used in coatings subjected to wear, corrosion and/or high temperature. The aim of this study was to analyze the effect of projection conditions on the microstructural characteristics and wear resistance of coatings of a Ni-Cr-Fe-B-Si alloy obtained by FS. For this purpose on steel carbon specimens, coating were obtained by varying the distance of application and the number of layers. Refuse in a furnace at 1160°C for 10 minutes was also apply. On coated samples the defect level, thickness and microstructure were analyzed. Vickers microhardness was determined and rubber wheel abrasion test ASTM G-65 type were performed. Obtaining a decrease in defect levels and better wear performance with decreasing distance of application and increase the number of layers.

title: Intradetrusor onabotulinumtoxinA injections are significantly more efficacious than oral oxybutynin for treatment of neurogenic detrusor overactivity: results of a randomized, controlled, 24-week trial

description: ABSTRACT Objective To prospectively compare the results of intradetrusor onabotulinumtoxinA injections and oral oxybutynin for urinary continence, urodynamic parameters and quality of life in patients with neurogenic detrusor overactivity due to spinal cord injury. Methods Adult patients under intermittent catheterization were randomized 1:1 to receive one injection of onabotulinumtoxinA 300U or oxybutynin 5mg, per oris, three times/day. Primary study endpoint was change in urinary incontinence episodes/24 hours and secondary study endpoints were maximum cystometric capacity, maximum detrusor pressure, bladder compliance and quality of life before randomization and at week 24. Results Sixty-eight patients participated in the trial. Significant improvements in urinary incontinence per 24 hours, all investigated urodynamic parameters and quality of life were observed in both groups. Compared with oral oxybutynin, onabotulinumtoxinA was significantly more efficacious for all parameters investigated. Non-response to treatment was higher for oral oxybutynin (23.5%) than onabotulinumtoxinA (11.8%). Dry mouth was the most common adverse in patients with oral oxybutynin (72%) and transient macroscopic hematuria in patients with onabotulinumtoxinA (28%). Only one patient with oral oxybutynin dropped out the study because of adverse effects. Conclusion The comparison of the two study drugs showed that onabotulinumtoxinA was significantly more efficacious than oral oxybutynin with regard to continence, urodynamic parameters and quality of life. Clinicaltrials.gov: NCT:01477736.

title: Molecular dynamics studies of amylose plasticized with Brazilian Cerrado oils: part I

description: Abstract Biodegradable polymers have become part of the realm of polymer science with specially when associated to renewable sources. Unraveling the plasticizer effect of natural occurring fatty acids in the Brazilian Cerrado on amylose oligomers was aimed in this work in an aqueous environment. Since the interactions within a material are of extreme importance to its molecular behavior, the main focus was directed to the molecular interactions whether intra or intermolecular type. Molecular Mechanics and Dynamics were carried out to shed light on this issue. The simulation results suggest the fatty acids could perform as efficient plasticizers for more complex polysaccharides such as starch. It also highlights the importance the solvation on the system stabilization, thus contributing to a clearer understanding of the chemical interactions role on plasticization. Our results provide a basis for simulating more complex systems such as a clay-mineral which will culminate in the parameterization for mesoscale studies.

title: First record of the soybean stem fly Melanagromyza sojae (Diptera: Agromyzidae) in the Brazilian Savannah

description: ABSTRACT The soybean stem fly [Melanagromyza sojae (Diptera: Agromyzidae)] is a pest widely distributed in the Asian continent. In Brazil, its occurrence has been reported since the 1980s, but it had not been reported in Brazilian Savannah areas yet. This is the first record of M. sojae in this region of great importance for the soybean world production. Specimens of the soybean stem fly were collected in a volunteer soybean area, in April 2018, in the Goiás state, Brazil, and sent for molecular identification. The similarity index of the collected specimens with M. sojae was higher than 99 %, thus confirming the identification of the species. The infestation level in the collection area was approximately 100 % of plants with damage caused by this insect. In Brazil, the occurrence of M. sojae, up to the present time, had been described as restricted to the southern states. This record raises the hypothesis that M. sojae is widespread in other agricultural areas of the Brazilian Savannah, and that its dissemination is favored by the maintenance of volunteer soybean.

title: Pedogenesis in an Archaeological Dark Earth – Mulatto Earth Catena over Volcanic Rocks in Western Amazonia, Brazil

description: ABSTRACT Archaeological Dark Earth (ADE) pedogenesis and pre-Columbian history are fundamental for understanding the biodiversity and pedodiversity of the Neotropical rainforest in the Amazon region. This study aimed to evaluate the morphological, physical, chemical, and mineralogical properties as well as NaOH-extractable organic matter [OM(NaOH)] in ADE and Mulatto Earth (ME) overlying volcanic rocks along a toposequence (four soil profiles) in western Amazonia, Brazil. The soil profiles show anthropic A horizons over an argic horizon (Bt) in the ADE (Humic, Pretic Luvisols) and Bi in the ME (Clayic, Dystric Cambisols). The soil-forming processes in all of the profiles are associated with organic matter accumulation, such as humification and melanization, besides the formation of organometallic complexes. Calcium, Mg, P, and organic carbon contents were higher in ADE compared to ME. High-activity clays are derived from parent volcanic material, distinguishing the soils studied from Amazonian soils (Tertiary Plateau, Terra Firme) and most Amazonian anthropic soils. The anthropic horizons generally have a large contribution from OM(NaOH), predominantly humin and humic acids associated with Ca, Mg, and poorly crystalline Al hydroxides. The results suggest that the anthropic driving-forces caused greater differences in pedogenesis than the soil location in the landscape.

title: Ractopamine concentration on the lipid profile of swine fat and meat

description: ABSTRACT: This study was conducted to evaluate the effect of ractopamine concentrations on swine fat and meat lipid profiles. Ninety finishing barrows, initially weighing 71.9±4.4kg, were distributed in a randomized block design in three ractopamine concentrations (0, 10 and 20ppm) with fifteen replicates of two animals in each. Gas chromatography was used to analyze the lipid profiles of backfat and meat. The inclusion of ractopamine in the diet changed (P&lt;0.05) α-linolenic acid and eicosatrienoic acid concentrations in the backfat but did not affect (P&gt;0.05) any of the other fatty acids or indexes evaluated. In the meat, a significant effect (P&lt;0.05) was observed on nine fatty acids evaluated, with a decrease (P&lt;0.05) in lauric, myristic, and palmitic fatty acids, and an increase (P&lt;0.05) in linoleic, γ-linolenic, dihomo-γ-linolenic, and eicosapentaenoic acid. Ractopamine also affected (P&lt;0.05) the concentration of α-linolenic and arachidonic acid in the meat (P&lt;0.05). The indexes evaluated were also affected (P&lt;0.05). Addition of 10ppm decreased the saturated fatty acid concentration, atherogenic index, thrombogenic index and omega 6: omega 3, while it increased unsaturated and polyunsaturated fatty acids concentrations. Ractopamine addition had less effect on the backfat than on the meat, and the 10ppm level improved the meat lipid profile.
