title: Silicon in wheat crop under water limitation and seed tolerance to water stress during germination

description: ABSTRACT Water stress during wheat seed germination and seedling establishment for affect the percentage and speed of germination. Silicon (Si) is related to plant tolerance to different types of stress, then the application of this nutrient in the mother plant during seed production could contribute to the improvement of the seed quality and, consequently, its tolerance to stress. The aim was to evaluate the effect of foliar application of silicon on the tolerance of wheat seeds, produced under different irrigation levels, to water stress during germination and initial seedling growth. Wheat seeds were produced under three irrigation depths (0, 50 and 100% of the total required irrigation) applied after the anthesis. The silicon was supplied in two doses by foliar application (0 and 5 mM of Si). The germination and seedling growth were performed under water stress induced by PEG 6000 at the -0.2; -0.4; -0.6 MPa osmotic potentials. In addition, in the control only distilled water was used. The reduction of the osmotic potential reduced seed germination, germination speed and seedling growth. Irrigation depths, as well as foliar application of Si, during seed production did not influence the physiological quality and tolerance of seeds to water stress during germination.

title: Effect of priming and different types of drying on the physiological quality of Urochloa ruziziensis seeds

description: Abstract: Seed vigor is one of the main limitations to meet the demanding forage market. In order to boost the productive potential and provide the satisfactory development of quality seeds and seedlings, it is necessary to develop techniques that provide quality and high productivity. With the Urochloa genus stands out in the seed production and quality, this study aimed to evaluate the effect of seed priming with sodium nitroprusside and to define the best drying method that allows the maintenance of the changes of this treatment in Urochloa ruziziensis seeds. The seeds were conditioned in sodium nitroprusside solution, as a nitric oxide donor, for 42 hours and later submitted to the following procedures: no drying, initial reduction of water content, thermal shock, slow and fast drying. The design was completely randomized, with ten treatments and four replications. Water content, germination, emergence and biochemical evaluations were performed. As results, it was observed that all drying methods evaluated reduced the water content of the seeds to 12%, recommended range for storage, with the exception of the treatment without drying that presented 30%. Regarding germination parameters, the treatment of initial reduction and quick drying obtained the best performance in germination and emergence. Moreover, the types of drying presented high rate of enzymatic activity of the antioxidant system, thus helping in the maintenance of redox homeostasis. According to the enzymatic activity and germination rates, it suggests that the rapid drying method after priming with nitric oxide is the best method for Urochloa ruziziensis.

title: Thermoenergetic optimization of a school building: discussion of the performance of four multiobjective evolutionary algorithms

description: The low thermoenergetic performance of buildings leads to increasing final consumption of electricity in the construction sector. The demand for air conditioning has contributed significantly to this increase and may be directly related to inadequate architectural planning. Through the establishment of a multi-objective optimization strategy, it is possible to identify performance improvement parameters for these buildings. This study discusses the performance of four multi-objective optimization algorithms applied to a standard project on early childhood education, developed by the Brazilian government program Proinfância, implemented in bioclimatic zone 2. Energy use intensity (IUE) for heating and cooling were defined as objective functions and five variables were changed: the thickness of the thermal insulation of the external walls and the floor, the absorptance of the external walls and roof, and solar orientation. The SPEA2 algorithm showed the best permance, achieving a solution capable of reducing IUE by approximately 92% in heating and 52% in cooling, when compared to the reference case.

title: Quality of Stylosanthes Campo Grande seeds coated with different materials

description: ABSTRACT The seed coating technique adds value to the seeds. This technique allows changing the seed size and shape, facilitating sowing, and also the application of essential nutrients to the good development of the plant in the post-germination phases. Therefore, the objective of this work was to evaluate the physical and physiological characteristics of Stylosanthes capitata/macrocephala coated with different materials. For the coating procedure, a N10 Newpack bench seed coating machine was used. The experimental design was completely randomized, with four replications and 50 seeds per plot distributed in 10 treatments. The different materials and their respective mixtures significantly altered the physical characteristics, the weight of a thousand seeds (WTS), water content (SWC), maximum diameter (DMA), and minimum diameter (DMI) of the seeds. Among the different materials, the sand coated seeds had the highest germination percentage (%G), germination velocity index (GSI), and first germination count (FGC). The maintenance of physiological attributes was observed in sand coated seeds (0.25 mm). Therefore, it is an alternative application of nutrients via seeds, due to the inert character of the sand. The mixing of the materials used in this work is not recommended.

title: Growth of pitaya seedlings according to the type of substrate and the frequency of irrigation

description: ABSTRACT The objective of this study was to evaluate the development of pitaya cuttings in different substrates under different frequencies of irrigation. The experiment was conducted from January to May 2017 in a greenhouse at Universidade Federal Rural da Amazônia, Capitao Poço, Pará, Brazil. A completely randomized 3 × 7 factorial design with four replicates was used. Pitaya plants were grown from cuttings in three types of substrates (S1: potting soil; S2: potting soil + cattle manure + wood shavings; and S3: washed sand) under seven irrigation frequencies (24, 48, 72, 96, 120, 144, and 168 h). There was interaction between treatments for root dry matter production, root length variables, the other variables showed no interaction between treatments. The greater development of new and vigorous tissues of the aerial part, the substrates with composition black earth and black earth + manure + sawdust are indicated, and the adoption of the irrigation frequency of 72 h or 96 h. The use of substrate based on black earth + manure + sawdust, allows savings in the rational use of water and energy with the application of the 96 h irrigation frequencies, maintaining satisfactory levels of development to the plant. The washed sand substrate can be used for propagation when this material is abundant, however, greater attention should be paid to the supply of water and nutrients to the plant.

title: Simulation with açaí fiber panels for improving speech intelligibility in classroom

description: Abstract Speech intelligibility in classrooms and students' learning capabilities are compromised by ambient noise and excessive reverberation, causing lack of concentration, tiredness and stress. The motivation for this study was the need for appropriate acoustic conditions in classrooms, where speech is the main sound source. In order to find a solution based on environmentally sustainable acoustic absorbers, this paper investigates the acoustical applications of açaí seed fibre, an abundant vegetable fibre in the Amazon region. Initially, measurements of acoustic parameters (Reverberation Time, Initial Decay Time, Clarity, Definition and Rapid Speech Transmission Index) were made in a classroom and then an acoustic numerical model of the room was developed. After validating the model, various configurations of absorber panels made with açaí fibre were analysed in the model to verify the influence on the acoustic quality of the investigated classroom. The results of the simulations indicate that açaífibre boards can be a very attractive solution, combining low cost and good performance.

title: Treatment of persistent epithelial ingrowth after Lasik with mechanical debridement, use of 20% alcohol and fibrin glue

description: ABSTRACT Lasik is the most often performed laser refractive surgery worldwide. Despite its efficacy and safety, some complications may occur. Epithelial ingrowth is a rare postoperative complication of Lasik, with an increased prevalence in cases of retreatment. Epithelial ingrowth is usually a nonprogressive and asymptomatic finding, which requires no treatment; however, in a minority of cases, symptoms may be clinically significant and diverse. Treatment is done with mechanical debridement of the affected interface, and additional interventions may be required. This study reported a case of recalcitrant epithelial ingrowth after Lasik, whichrelapsed four times after mechanical debridement, flap lift and laser ablation. In the fifth intervention, the patient was finally treated with a combined scraping/use of 20% alcohol and fibrin glue. However, regression of epithelial ingrowth and better visual acuity were only observed some months after the intervention, which shows the importance of waiting for better vision in the postoperative period, thus avoiding new reinterventions.

title: The Efficiency of Railways Specialized in Transporting Iron Ore and Pellets

description: ABSTRACT Objective: the objective is to compare the relative efficiency of the railways specialized in transporting iron ore (MFe) and pellets (PLMFe), which are part of the assets of mining companies and pellet plants considering the 2016 scenario. Methods: the methods used were the data envelopment analysis (DEA) technique, with the application of the output-oriented constant returns scale (CRS) model; the initial combinatorial multicriteria method for choosing the input variables; and Tobit regression as a validation strategy for the DEA model. Results: of the twelve railways evaluated, three railways were identified as efficient: Estrada de Ferro Carajás, Fortescue, and Mount Newman. Conclusions: the applied model was considered a good method to evaluate the efficiency of railways specialized in transporting MFe and PLMFe, as it determined the efficiency of each railway, suggesting the necessary increase in the output variable or adjustments in the input variables so that the railways reach the efficiency frontier. With that, companies can use the results of this study to guide future improvements to make their railways more efficient or maintain them on the frontier of efficiency.
