title: The effect of public policies and local aspects on economic development: an empirical analysis based on the municipalities of Minas Gerais

description: Abstract This research used cross-section data, from 2016, to analyze the effect of public spending distribution and some economic, demographic and political preferences on municipalities’ development from Minas Gerais (i.e.: Índice Mineiro de Responsabilidade Social - IMRS) and their sub-dimensions (i.e.: education, health, social vulnerability, security, sanitation/housing/environment and culture/sport/leisure). Thus, the variables were selected by Extreme Bounds Analysis - EBA and econometric-spatial models were estimated. The results indicate that development is typical from smaller cities, far from the capital (safer), with higher elderly people proportion (less subject to crime), lower fertility (trait of safer and less vulnerable places), good tax autonomy (attribute of less vulnerable areas, with more sanitation and culture/leisure), lower spending on education and public administration and higher on housing. Furthermore, the results minimize the state (i.e.: municipal administration) and the local productive profile relevance on development and reveal negative externalities from the state capital.

title: Extraction Method for Determining Florpyrauxifen-benzyl Herbicide in Soil

description: Florpyrauxifen-benzyl is the new active ingredient authorized by Brazilian legislation, which acts as herbicide and may be used to control weeds in rice cultivation, but studies on toxicity to humans and the environment are still under review. Due to recent insertion in the world pesticide market, there are still few studies related to the extraction and detection methodologies of this compound. Therefore, this study aimed to optimize and validate solid-liquid extraction with low temperature purification (SLE-LTP) for determining florpyrauxifen-benzyl in soil using high-performance liquid chromatography coupled to a diode array detection (HPLC-DAD). The results showed that the best conditions were achieved using Poroshell column, a temperature of 30 °C, mobile phase composition of acetonitrile:water (85:15 v/v) acidified with formic acid 0.1% (v/v), a flow rate of 0.3 mL min-1, and 243 nm as the wavelength. The best extracting phase was acetonitrile acidified with formic acid 0.1% (v/v) which achieved a recovery rate ca. 100% and relative standard deviation (RSD) less than 3.9%. The methodology was precise, accurate, linear and selective, with a limit of quantification of 20 µg kg-1. The stability study of this compound in soil showed that approximately 17.5 days is the half-life of florpyrauxifen-benzyl in soil.

title: Ammonia Removal in Activated Carbons Prepared from Olive Oil Industry Waste

description: Activated carbons (ACs) from olive stone were prepared using CO2, steam, KOH, and H3PO4 as activating agents. The resultant activated carbons were characterized by proximate and ultimate analysis, N2 adsorption (Brunauer-Emmett-Teller (BET) method), iodine number, Boehm titration, temperature-programmed desorption (TPD), and Fourier transform infrared spectroscopy (FTIR). Ammonia (NH3) was used as a test molecule to be adsorbed. The BET surface areas of the ACs obtained ranged from 1000 to 1986 m2 g-1. Type I isotherms were obtained for all the samples, although steam and H3PO4 ACs showed a significant mesopore contribution. KOH activation resulted in carbon with a high microporosity (98%) and high iodine adsorption (1030 mg g-1). KOH AC prepared with a KOH/pyrolyzed char weight ratio of 2 and at 900 °C showed the highest NH3 adsorption (252 mg g-1), favored by the high microporosity and adequate acidity. Chemical activation (KOH and H3PO4) promotes higher NH3 adsorption than the physical ACs prepared (CO2 and steam). Langmuir and Freundlich adsorption equilibrium models were used to correlate the NH3 adsorption isotherms, obtaining the best fit for the Freundlich equation. The results indicated that olive stone-based activated carbon could be used for commercial AC to remove NH3 from gaseous streams.

title: Nodular lymphocytic conjunctivitis in a horse - case report

description: ABSTRACT The case of an equine with nodular lymphocytic conjunctivitis is described. A 14-year-old crossbred mare was seen presenting with development of a mass in the nasal angle of the right eye, behind the third eyelid. The tutor reported slow growth over 4 years, always accompanied by epiphora, and that no treatment had been performed prior to consultation. The histopathological and immunohistochemical results found a nodular, subepithelial structure, composed predominantly of densely packed small lymphocytes. Through the exams, associated with studies with monoclonal anti B lymphocyte antibodies and polyclonal anti T lymphocyte antibodies, the diagnosis of nodular lymphocytic conjunctivitis was reached. Only clinical pharmacological treatment was chosen, based on the use of topical and intralesional hydrocortisone acetate. After one month of treatment the mass completely disappeared without sequelae.

title: Metabolomics Analysis of Combretum lanceolatum Roots in the Presence of Its Endophytic Fungi

description: The aim of this work was to identify and quantify the metabolites present in the roots of Combretum lanceolatum inoculated with its endophytic fungi. The metabolomics was accomplished using the 1H nuclear magnetic resonance (NMR) spectral data and evaluated via rNMR software and Madison Metabolomics Consortium Database (MMCD). The principal component analysis (PCA) and partial least squares-discriminant analysis (PLS-DA) showed that plants inoculated with Trichoderma spirale (Ts) present differentiation and discrimination over the time compared to control. Seven days after Ts fungal inoculation, 15 metabolites were identified at different concentrations comparing to the control plants. The plants inoculated with Ts fungus present the metabolites spermidine and pantothenate in higher concentrations and 3-hydroxybutyric acid and b-alanine in lower concentrations compared to control plants, indicating any response to biotic stress. These metabolites are involved in various plant processes, including secondary metabolites biosynthesis, energy metabolism and self-defense. Therefore, this work demonstrates the diversification of primary metabolites composition influenced by endophytes inoculation.

title: Mineral contents in bone and liver of sheep with or without periodontitis

description: ABSTRACT Due to the supposed involvement of minerals in cases of ruminant periodontitis, this study aimed to analyze the concentrations of phosphorus (P) in bone, and cobalt (Co), copper (Co), iron (Fe), zinc (Zn) and selenium (Se) in liver of a cohort of sheep affected or not by periodontitis. From an outbreak of the disease in 2011 in Pará state, Brazil, rib and liver samples were obtained from 22 sheep with periodontitis and seven samples from healthy animals. Based on the concentrations of the different minerals in the tissues, we concluded that there was no relationship between periodontal disease in sheep with any mineral deficiency status. In contrast, most of the minerals in the tissues were above or within the recommended concentrations in bone and liver. Within the various aspects which until now have been studied regarding periodontitis in ruminants, the results obtained here corroborate the fact that periodontal disease in sheep is an infectious disease and it is not a consequence of the deficiency or excess of mineral elements in the diet.

title: Spatial and temporal distribution and bioinsecticides control of olive leaf moth in an olive orchard in Southwest of Paraná, Brazil

description: ABSTRACT: We verified the spatial and temporal distribution of the olive leaf moth (Palpita forficifera Munroe, 1959) in a new potential region for olive cultivation and evaluated the bioinsecticides effectiveness to control this pest. The experimental orchard composed by Koroneiki and Arbequina cultivars was planted in Pato Branco, Southwest region of Paraná, Brazil. In the field, larvae counts were performed weekly on 25 plants of each cultivar, for 12 months, to verify the spatial and temporal distribution. Furthermore, in laboratory conditions, second instar larvae of P. forficifera were fed with olive leaves treated with Azadirachta indica oil, Bacillus thuringiensis, Metarhizium anisopliae and Beauveria bassiana, and the effectiveness in the larvae mortality was used to compare four bioinsecticides and control. The P. forficifera larvae occurred mainly during the three summer months, had a host preference for the ‘Arbequina’ (68.9% of total larvae) and occurred at random distribution patterns throughout the orchard. The A. indica oil and B. thuringiensis both caused almost 100% larvae mortality under laboratory conditions.

title: Occurrence of intersexuality in Mugil curema from an estuary of the North coast of Santa Catarina, Brazil - case report

description: ABSTRACT This study describes the occurrence of reproductive changes in a mullet (Mugil curema) from the Babibtonga Bay, Santa Catarina. Gross and microscopic findings indicated changes in the reproductive system that were characterized by the presence of both male and female gonads, nearing sexual maturity, which was compatible with the diagnosis of intersex. It was not possible to identify predisposing factors that may have contributed to the development of this condition. However, as this species of fish may have their reproductive development affected by anthropogenic influence, it is important to permanently monitor this kind of environment. Considering the number of fish belonging to this species that was examined (n=433), the estimated prevalence for intersexuality was 0.23% (confidence interval: 0.00 to 0.68%, with confidence level of 95%). The findings in this study support the diagnosis of intersexuality in M. curema from the Babitonga Bay, which is the first documented case of this condition in this species on the coast of Santa Catarina, Brazil.

title: Revisiting Regional Innovation Systems: Theory, Practice, Policies, and Agenda for Brazil

description: Abstract The regional innovation systems (RIS) approach emerged in the early 1990s and has gone through several conceptual and methodological improvements. A fundamental aspect of this approach is the recognition that economic space and geographical proximity between the agents have significant effects both in the generation and in the dissemination of new knowledge, with important implications innovation-based regional policy. This paper aims to present a systematization of the literature on the SRI approach and, at the same time, contribute to the debate on innovation systems in Brazil. Based on a thorough literature review, the paper examines the most relevant conceptual and empirical works on SRI and, therefore, presents a wide range of obstacles and weaknesses that can hinder regional innovation. Finally, the paper concludes with a research agenda aimed at developing countries, showing the existing links between the debate on RIS and the local context in these countries.
