title: Dormancy overcoming and germination test in Piptadenia stipulacea (Benth.) Ducke seeds

description: ABSTRACT Piptadenia stipulacea (Benth.) Ducke presents slow and uneven germination due to integumentary dormancy. In addition, there are no standardized indications as to the temperature and substrate for conducting the germination test in the laboratory. Thus, the objective was to evaluate methods of dormancy overcoming, temperatures and substrates in the germination and vigor of P. stipulacea seeds. For this, two experiments were installed, the first one in a completely randomized design, with 4 replicates of 25 seeds and treatments to overcome dormancy were: immersion in water at 100 °C for 1; 2; 3; 4; 5 and 6 min; immersion in concentrated sulfuric acid (H2SO4 - 98% P.A) for 1; 4; 7; 10 and 13 min; scarification on sandpaper no 80; in the region opposite the micropyle and intact seeds. At 21 days after sowing, emergency, emergency speed index and mean emergency time were evaluated. In experiment II, the experimental design was completely randomized in a 4 x 6 factorial scheme, with four replicates of 25 seeds, using the substrates between sand, paper, paper roll and vermiculite at temperatures of 20; 25; 30; 35; 40 °C and alternated 20-30 °C, the variables analyzed were first count, germination, mean germination time and germination speed index. In order to overcome seed dormancy of P. stipulacea, it is recommended that the pre-germinating treatment be set in the region opposite to the micropyle, and to evaluate the germination and vigor of these seeds, the temperature of 30 °C and 20-30 °C can be used with the roller substrate of paper.

title: Characterization of different techniques for obtaining minced fish from tilapia waste

description: Abstract The majority of tilapia farming is used for the production of fillets, resulting in the generation of waste that can be used to increase food stocks by producing minced fish. The aim of this study was to characterize and evaluate the viability of boiling and mechanical techniques for obtaining minced fish in relation to performance, physical-chemical and microbiological parameters and to reduce the waste generated in the process of filleting Nile tilapia. Based on performance outcomes, the mechanical technique proved to be 12% more efficient than the boiling one. The cost of the boiling technique was higher due to performance and operating costs. In both techniques microbiological alterations were not observed. Centesimal analysis results showed a difference in humidity between the techniques, which was expected due to loss of water during the boiling process, which possibly also affected protein levels. Over all, the use of a deboning machine allied lower operating cost, better performance, quality and practicality. The debone machine technique it's feasible considering the large volume of waste generated daily on fish farms, which requires a speedy and effective disposal. Further, makes possible obtaining a nutritional raw material of high added-value and contributing to the reduction of environmental impacts.

title: Wobbly syndrome in an Africa pygmy hedgehog (Atelerix albiventris): neuropathological and immunohistochemical studies

description: ABSTRACT: A three-year-old female African pygmy hedgehog (Atelerix albiventris), born and domiciled in Brazil, presented apathy, prostration, and difficulty to stay standing. Its parents were siblings but did not present clinical signs related to this condition. As its clinical condition worsened, the animal was euthanized and referred for necropsy. No gross lesions were found in the central nervous system (CNS). Histologically, there was vacuolation with axonal degeneration in the white matter of the CNS and in peripheral nervous tissue. The Kluver-Barrera (KB) stain confirmed demyelination in vacuolated areas. Immunohistochemistry using several neural markers confirmed astrocytosis and microgliosis associated with vacuolated areas. In addition, there was a mild decrease in the immuno intensity of myelin proteolipid protein (PLP) in these areas. These results suggest a genetic origin of the present demyelination, which resulted in the wobbly syndrome described in this report.

title: Controlled Dehydration of Fe(OH)3 to Fe2O3: Developing Mesopores with Complexing Iron Species for the Adsorption of β-Lactam Antibiotics

description: In this work, efficient adsorbents for β-lactam antibiotics based on mesoporous iron oxide containing surface [FeOx(OH)y] sites were produced by controlled precipitation of iron hydroxide and thermal treatment at 150, 200, 300 and 450 ºC (150FeOH, 200FeOH, 300FeOH and 450FeOH, respectively). Mössbauer, X-ray diffraction (XRD), thermogravimetry-mass spectrometry (TG-MS), Fourier transform infrared spectroscopy (FTIR), Raman, Brunauer-Emmett-Teller method (BET), scanning electron microscopy (SEM) and elemental analyses showed that the temperature caused a gradual dehydroxylation process with a significant increase of the mesoporous surface area (e.g., 114-142 m2 g-1 with 46-59% mesopores, i.e., 0.04-0.09 cm3 g-1) and approximate compositions of FeO1.06(OH)0.89 for 150FeOH up to FeO1.38(OH)0.26 for 450FeOH. The material 150FeOH showed high adsorption capacities of ca. 42 and 58 mg g-1 for amoxicillin and ceftriaxone, respectively. Experiments assessing the effect of NO3-, Cl-, competitive PO43- adsorption and H2O2 decomposition suggest that the [FeOx(OH)y] surface sites located in the mesopores are involved in the efficient adsorption by complexation of the β-lactam antibiotics.

title: MODELING AND SOLVING THE TRAVELING SALESMAN PROBLEM WITH PRIORITY PRIZES

description: ABSTRACT This paper addresses the Traveling Salesman Problem with Priority Prizes (TSPPP), an extension of the classical TSP in which the order of the node visits is taken into account in the objective function. A prize p ki is received by the traveling salesman when node i is visited in the k-th order of the route, while a travel cost c ij is incurred when the salesman travels from node i to node j . The aim of the TSPPP is to find the maximum profit n-node tour. The problem can be seen as a TSP variant with a more general objective function, aiming at solutions that in some way consider the quality of customer service and the delivery priorities and costs. A natural representation for the TSPPP is here grounded in the point of view of Koopmans and Beckmann approach, according to which the problem is seem as a special case of the quadratic assignment problem (QAP). Given the novelty of this TSP variant, we propose different mixed integer programming models to appropriately represent the TSPPP, some of them based on the QAP. Computational experiments are also presented when solving the MIP models with a well-known optimization software, as well as with a tabu search algorithm.

title: An electronic warning system helps reduce the time to diagnosis of sepsis

description: ABSTRACT Objective: To describe the improvements of an early warning system for the identification of septic patients on the time to diagnosis, antibiotic delivery, and mortality. Methods: This was an observational cohort study that describes the successive improvements made over a period of 10 years using an early warning system to detect sepsis, including systematic active manual surveillance, electronic alerts via a telephonist, and alerts sent directly to the mobile devices of nurses. For all periods, after an alert was triggered, early treatment was instituted according to the institutional sepsis guidelines. Results: In total, 637 patients with sepsis were detected over the study period. The median triage-to-diagnosis time was reduced from 19:20 (9:10 - 38:15) hours to 12:40 (2:50 - 23:45) hours when the manual surveillance method was used (p = 0.14), to 2:10 (1:25 - 2:20) hours when the alert was sent automatically to the hospital telephone service (p = 0.014), and to 1:00 (0:30 - 1:10) hour when the alert was sent directly to the nurse's mobile phone (p = 0.016). The diagnosis-to-antibiotic time was reduced to 1:00 (0:55 - 1:30) hours when the alert was sent to the telephonist and to 0:45 (0:30 - 1:00) minutes when the alert was sent directly to the nurse's mobile phone (p = 0.02), with the maintenance of similar values over the following years. There was no difference in the time of treatment between survivors and non-survivors. Conclusion: Electronic systems help reduce the triage-to-diagnosis time and diagnosis-to-antibiotic time in patients with sepsis.

title: Different formulations of camu-camu popsicle: characterization, vitamin C and sensorial analysis of an opportunity to family agroindustry

description: Abstract The high levels of vitamin C in camu-camu have stimulated the interests of extractivists, farmers and consumers. The aim of this study was to characterize five accessible for family agroindustry different formulations of camu-camu popsicles and assess their acceptance. A completely randomized design was used and the treatments consisted of five different popsicle formulations: camu-camu pulp (T1 and T2: 27%, T3 and T4: 20.8%; T5: 61%), water (T1 and T2: 43.5%, T3 and T4: 20.8%; T5: no water), whole milk powder (T1 and T2: 14.7%, T3 and T4: 29.2%; T5: 18.3%), sugar (T1 and T2: 14.7%, T3 and T4: 29% and T5: 20.6%), neutral alloy and emulsifier. The formulations were processed and the popsicles were evaluated for pH, soluble solids, titratable acidity, vitamin C, acceptability index (SS/TA) and macro and micro nutrients were identified. In the sensorial analysis, the popsicles were evaluated for appearance, color, flavor, texture and purchase intent by 40 untrained tasters. The acceptance of the camu-camu popsicles was lower when the formulation was more diluted. Formulations T3, T4 and T5 showed the most wanted qualitative attributes and these preparations received top scores in the sensory analysis.

title: Mannheimia haemolytica pleuropneumonia in goats associated with shipping stress

description: ABSTRACT: This study described the epidemiological, clinical, pathological and bacteriological aspects of Mannheimia haemolytica pleuropneumonia in goats associated with shipping stress. Forty goats transported from the Northeast to the Southern region of Brazil died during shipment, or 2-3 days after unloading. Clinical signs included dyspnea, mucopurulent nasal discharge, and coughing. All goats were necropsied, and multiple tissues were collected for histopathological analysis and involved agent identifications. All lungs showed pulmonary consolidation, predominantly affecting the cranioventral lobes, in addition to the marked fibrinous pleuritis, pleural thickening, and pleural adhesions, that affected 90% of the goats. Histologically, there was fibrino-suppurative pleuropneumonia characterized by a diffuse neutrophilic infiltrate admixed with fibrin. Non-hemolytic [85% (34/40)] and hemolytic [15% (6/40)] species were obtained in bacteriological culture. Fir Mannheimia spp. was reported in 26 isolates and subsequently confirmed as M. haemolytica (99% identity), after amplification and partial sequencing of the 16S rDNA gene. Stress may trigger the development of bacterial pleuropneumonia in goats, and non-hemolytic strains of M. haemolytica may cause this condition in goats with severe immunosuppression.

title: Fast Determination of Iodine Number of Biodiesel Using Capillary Zone Electrophoresis with Multi- and Single-Point Calibration

description: A new and fast method was developed to determine the iodine number of biodiesel samples by capillary zone electrophoresis (CZE). In this procedure, the biodiesel sample reacts with Wijs solution in the presence of a catalyst and all the remaining iodine monochloride is converted to the iodide ion, which is quantified by CZE. Only small amounts of sample and reactant are required and µL level amounts of chloroform and Wijs solution. The reaction time was reduced to 3 min and the total analysis time is less than 15 min. The simplicity and speed of the method can be further enhanced by using single-point calibration. The limits of quantification (LOQ) and determination (LOD) values were better than 0.6 and 0.18 g per 100 g of biodiesel. Instrumental, intraday, and interday precisions were better than 1.13, 1.04 and 6.02% relative standard deviation (RSD). The accuracy was statistically verified by comparison with the standard method EN 14111.
