title: Oviposition preference and biological performance of Ceratitis capitata in Anacardiaceae, Cactaceae and Vitaceae fruit

description: ABSTRACT: The objective of this study was to compare the use of fruits of great economic and social importance for the northeast of Brazil by Ceratitis capitata Wied. (Diptera: Tephritidae) for oviposition, larval development, size and longevity of adults. Fruits of mango (Mangifera indica L.), quiabento (Pereskia bahiensis Gürke), forage palm [Opuntia fícus indica (L.) Mill] and grape (Vitis vinifera L.) were used, as well as flies from a hybrid laboratory population. Initially, four treatments (fruits) and six replications were used; the fruits were offered to 10 C. capitata couples, with later (96 hours) egg count. The second was conducted with six treatments and 10 replicates, offering two types of fruits simultaneously, combined two to two, to 10 C. capitata couples. The last bioassay comprised four treatments and six replicates, where 20 g of fruit were offered to 20 first-instar C. capitata larvae. After six days, the larvae were placed in plastic pots containing vermiculite until pupation, quantifying larval and pupal periods, viability and pupal mass, besides longevity and adult size. The data were submitted to ANOVA using the R Core Team software. Ceratitis capitata oviposits and completes its biological cycle in the four hosts studied, exhibiting no preference for oviposition and low biological performance in quiabento fruits. It yielded smaller adults and lower grape survival. Cactaceae palm and quiabento allow the survival of C. capitata in the laboratory, and this knowledge has been reported for the first time, proving that they can act as alternative hosts in the field.

title: Slow Cook-Off Simulation of PBX Based on RDX

description: ABSTRACT: Cook-off tests are commonly used to assess thermal behaviour of energetic materials under external thermal stimuli. Numerical simulation became a powerful tool to reduce the costs with experimental tests. However, numerical simulations are not able to predict the violence of thermal response, but instead accurately reproduce radial heat flow in the test vehicle and satisfactorily predict the delay time to ignition and ignition temperature. This paper describes the slow cook-off simulation of 3 selected PBX based on RDX in a small-scale test vehicle, using the equilibrium equation of Frank-Kaminetskii and testing 2 kinetic models: Johnson-Mehl-Avrami (n) and Šesták-Berggren (m, n). The influence of successive addition of binder elements (HTPB, DOS, and IPDI) on slow cook-off results of selected PBX was assessed. The variation of ±10% in input data was performed to determine the influence on the slow cook-off results. Results showed that the addition of binder elements reduces the delay time to ignition as well as ignition temperature and that the Šesták-Berggren (m, n) kinetic model generates smaller values and with less deviation linked to the variation of input data. The selection of kinetic model as well as the variation of ±10% in input data had a negligible influence on the slow cook-off results of cured PBX.

title: Thermal requirements and age-specific life tables of cowpea aphids in cowpea under natural field conditions

description: ABSTRACT: Thermal requirements and life tables of insects are important tools in the ecological management of pests. Thus, this study aimed to construct age-specific life tables for Aphis craccivora at different times of the year and, based on their thermal requirements, predict the occurrence of adults under field conditions. To that end, aphids of known age were kept in cages over cowpea plants at different times of the year - November 2016 and March, April, and June 2017 - at the Agricultural Sciences Center of the Federal University of Piauí. Parameters of development, fertility, and mortality were observed daily, allowing us to construct age-specific life tables, as well as an accumulated degree-day model to predict adult occurrence. The time of year affected the first and second stages of development of the cowpea aphid, the nymphal and reproductive periods, longevity, the biological cycle, the number of nymphs produced per female, the daily production of nymphs per female, life expectancy (ex), and survival (Lx). However, the fertility life tables showed significant differences only in the net reproduction rate (R0). The proposed degree-day model reached an accuracy of one day or more than the observed value, with a maximum error of 12.9%. We concluded that the proposed model is adequate to predict the occurrence of adults in the field and that the population parameters of A. craccivora in cowpea are negatively affected during November and positively affected in June.

title: Decrease in the Inflammatory Marker TNF-α after Consumption of Flaxseed by Hypercholesterolemic Rabbits

description: Abstract Background: Functional foods such as flaxseed have been commonly consumed to prevent atherosclerosis. Objectives: To assess the effects of flaxseed in atherogenesis in rabbits consuming a high-cholesterol diet. Methods: Thirty male albino rabbits were randomized to three groups based on a 12-week dietary treatment: control group (G1), standard diet; high-cholesterol diet (G2), standard diet plus 0.25% cholesterol from lyophilized eggs; and high-cholesterol plus flaxseed (G3), similar diet as G2 plus flaxseed. Biochemical (total cholesterol [TC], high-density lipoprotein [HDL-C], low-density lipoprotein cholesterol [LDL-C], and triglycerides) and immunohistochemical (intercellular adhesion molecule 1 [ICAM-1] and tumor necrosis factor alpha [TNF-α]) analyses were performed in all groups. P values &lt; 0.05 indicated statistical significance. Results: At 12 weeks, serum TC levels increased significantly in G2 and G3 compared with G1. Serum LDL-C levels were higher in group G2, and the increase in group G3 was approximately six times lower than that in G2. HDL-C levels increased in all groups, with the highest increase observed in G2. Triglycerides levels in G3 decreased by ~70% and differed significantly in G1 and G3 (p = 0.034) and G2 and G3 (p = 0.015). ICAM-1 levels increased only in aortic segment 4 in G3. TNF-α levels in G3 were similar to those in the control group, while the levels in G2 were greater than twice as those in the control group (p &lt; 0.05). Conclusions: The group fed with a functional diet (flaxseed) showed decreased development of atherosclerosis, reduced serum triglycerides levels, and lower TNF-α levels on immunohistochemistry.

title: Soroprevalence of bovine alphaherpesvirus type 1 (BoHV-1) and risk factors associated with dairy properties of the municipality of Senador Guiomard, Acre, Brazil

description: ABSTRACT Bovine alphaherpesvirus type 1 (BoHV-1) is the etiological agent responsible for serious infections that compromise the respiratory and genital tracts of affected cattle. In order to estimate the seroprevalence of BoHV-1 and to identify the associated risk factors in dairy farms in the city of Senador Guiomard, Acre, Brazil, the present study was carried out through the analysis of 180 blood serum samples submitted to the screening of anti-BoHV-1 by the virus neutralization test (VN) and by means of the evaluation of the epidemiological questionnaire applied in the eight investigated properties. The prevalence of seropositivity for BoHV-1 was 61.1%, ranging from 43.3 to 86.2% among the analyzed properties. The variable absence of veterinary assistance showed statistically significant association (odds ratio — OR = 2.10; p &lt; 0.001) with alphaherpesvirus infection. The results demonstrate that the frequency of BoHV-1 is high and needs to be controlled through prophylactic and health management measures.

title: Word Tasting: towards a sensorial experience of language and thought in the actor's work

description: Abstract: Starting from the metaphorical conception, the word is nutrient, we propose a series of four exercises as a word tasting to investigate the sensory aspects of language and thought in the actor's work. Through an exploration of the proximity between speaking and eating, the exercises seek to stimulate awareness of the way in which words reverberate through the entire body. The proposal aims to reduce the mechanical control of organic processes and the direct manipulation of the voice in accordance with preconceived aesthetic notions. At the same time, it proposes to provoke a deeper physical-intellectual-emotional-sociocultural experience of the text in the theatre.

title: GENETIC DIVERGENCE AMONG COTTON GENOTYPES GROWN IN THE MAIN SEASON AND OFF SEASON

description: ABSTRACT The objective of this work was to evaluate the agronomic performance and estimate the genetic divergence of 18 cotton genotypes grown in the main season (sowed in December, 2012) and off season (sowed in January, 2013), considering their agronomic characteristics and resistance to Ramularia leaf spot. A randomized block experimental design was used, with five replications. The characteristics evaluated were plant height, first branch height, position of first fruiting branch, height of first fruiting branch, length between nodes, number of nodes, average number of bolls per plant, average boll weight, area under the disease progress curve (AUDPC) related to the Ramularia leaf spot severity, weight of 100-seed from the plant middle third, fiber percentage, average production per plant, yield and cotton fiber quality. The results were subjected to individual and joint analysis of variance and the genetic divergence was estimated according to multivariate procedures (Mahalanobis' generalized distance and Tocher's optimization method). The dissimilarity matrices were summed to estimate the genetic divergence, considering both growing periods. Genetic variability was found among the genotypes evaluated, in both the main season and off season. The characteristic that most contributed to the genetic divergence in the main season was the production per plant and, in the off season, was the fiber percentage. According to the results of the present work, the crosses between the genotypes BRS-335 and FMT-707; FM-910 and FMT-707; and IMA-08-12427 and FMT-707 are recommended.

title: PLOT SIZE AND NUMBER OF REPLICATIONS FOR CASTOR BEAN AT DIFFERENT SPACING BETWEEN PLANTS

description: ABSTRACT: Proper planning of experiments in the culture of castor bean is one of the ways to maximize the research information. The aim of this study was to determine the optimum plot size and number of replications and the influence of spacing between plants in experiments involving castor bean crops. The experiment with the hybrid Sara was conducted at the Federal University of Santa Maria in 2010 with a spacing of 1.2 m between rows and between plants of 0.4, 0.6 and 0.8 m. Each plant was evaluated taking into account: the number of racemes, fruit weight, the average length of the racemes, and fruit number, with the plant identification by the order number of the row and the number of plants within the row. The optimum plot size is eight plants for all spacings and all variables. However, the area of optimum plot size inside the spacing depends on the area occupied by the basic unit. Thus, the plot area is 3.84, 5.76 and 7.68 m2 for each spacing of 0.4, 0.6 and 0.8 m, respectively. Twelve replications in randomized block design, are sufficient to identify, as significant at 5% probability, differences between treatment means of 27%.

title: Evaluation of the influence of the urban context on the available solar radiation for energy generation

description: Abstract In this work a methodology was developed to evaluate the influence of urban context on the usable solar radiation for energy generation through photovoltaic modules on building envelope. The methodology is based on computer simulations using the programs Diva-for-Rhino and EnergyPlus. Two Brazilian cities with different climate were selected for the study: Florianopolis and Fortaleza. Different urban contexts were defined considering buildings with uniform height (Uniform Context) and random height (Random Context). Through the analysis of solar radiation on the building envelope the influence of shading on energy generation for the different office building types was determined. In addition, strategies for PV application on building envelope through the detailed analysis of available solar radiation were developed. The results showed that within an uniform context PV modules are a good option for energy generation. For buildings up to 6 floors enough energy can be generated to achieve an equalized annual energy balance. For this context the area with highest potential for energy generation is the roof. For the random contexts the facades of the high-rise buildings are an interesting option for PV application as well.

title: Analysis of quartz floatability using design of experiments

description: Abstract Quartz floatability in cationic reverse flotation depends on the suitable choice of surfactant type and the conditions under which they are applied. The design of experiments (DOE) allows the evaluation of process variables, in a structured and independent way, with statistical validation and a limited number of tests. Tests of microflotation of quartz, in the size range -150 +75 µm, using factorial design of experiments, showed that etherdiamine leads to higher level of quartz floatability than ethermonoamine, favored by increase in collector concentration, at the high level of pH tested (11.0). Floatability values above 90% were achieved with the use of 3 mg/L of ether diamine for both pH levels, while with ether monoamine the target was reached only at pH 11.
