title: Surface morphology and repellency mechanism investigation of Salvinia molesta plant

description: ABSTRACT Bionics is a versatile tool with a technological potential, which designers use to search for signs and clues about functional elements and mechanisms in nature that allow for the development of products. The purpose of this study was to analyze the morphology of the aquatic plant Salvinia molesta, aiming to determine the water repellency of its leaf surface and then reproduce its properties in the design of products that require water repellent surfaces. The structure of the plant’s trichomes, analyzed by scanning electron microscope, enabled the identification of the sites where wax was present and absent. The contact angle of the leaf surface was measured, indicating the water absorption capacity of the plant’s surface. Quantification and distribution analyzes of the wax on the leaf surface were also performed. The SEM analysis revealed that the plant has no wax on its trichomes. The measured contact angle and inclination angles allied to the SEM analysis indicated that the plant has hydrophobic characteristics.

title: Physiology and production of sesame genotypes BRS-Seda and Preto under organomineral fertilization

description: ABSTRACT Sesame is an oilseed that has low demand of water; it is widely grown in tropical regions, but few studies had been conducted on its mineral nutrition. The objective of this study was to evaluate physiological and production variables of two sesame genotypes (BRS-Seda and Preto) varying the organomineral fertilizer doses, via fertigation. The genotypes were grown under field conditions during the 2014/2015 dry season, in an agricultural area in Lagoa Seca, PB, Brazil. The two genotypes were subjected to five doses (0, 30, 60, 90 and 120% of the nutritional requirement of the crop) of an organomineral fertilizer based on sugarcane vinasse, and to an additional treatment consisting of mineral fertilizer (100% of the crop requirement). The experiment was conducted in a randomized block design, in a (2 x 5 + 2) factorial arrangement, with 12 treatments and 4 repetitions, totaling 48 plots. Among the physiological variables evaluated, only internal CO2 concentration was affected by the organomineral fertilizer doses. The number of fruits per plant, fruit weight per plant, seed weight per plant, and 1000 seed weight of both cultivars were favored by the organomineral fertilization. The organomineral fertilizer dose of 120% provided better results for the two sesame genotypes than those found with the mineral fertilization.

title: Evaluation of dimensional deviation in nickel-base, Inconel 718, alloy after grinding under different cooling-lubrication techniques

description: ABSTRACT Inconel 718 is a nickel based alloy that has high resistance to fatigue and creep, ductility, stiffness, chemical inertia and the ability to operate at high temperatures. These properties make the Inconel 718 attractive to be employed in high performance parts. These parts require narrow dimensional and geometric tolerances that can usually be achieved by the grinding process. However, this material presents low machinability, especially because its susceptibility to thermal damages during grinding. In this sense, both lubrication and cooling properties of the cutting fluid must predominate during grinding of this alloy, so any attempt to improve the cutting fluids properties will represent a great contribution. Also, specific literature is still scarce in scientific studies about evaluation of dimensional deviation of ground workpieces and how they are affected by the cutting parameters. In this sense, this work aims to contribute with knowledge in the grinding field by evaluating the influence of different cooling-lubrication techniques on the dimensional deviation of the Inconel 718 workpieces. The machining atmospheres tested were: dry and with cutting fluid. For the latter, cutting fluid was applied via conventional coolant technique (flood) and via the Minimum Quantity Lubrication (MQL) technique. Two values of depth of cut 20 µm and 40 µm were testes as input parameters. The results showed that the lowest values of depth of cut (20 µm) generated smaller dimensional deviations, as would be expected. In addition, grinding with the MQL technique proved to be advantageous in generating the lowest dimensional deviation values. After measurements of the dimensional deviations, IT tolerance grades were calculated and they were within the IT6 – IT5 range, which is in agreement with the one usually mentioned in the specific literature for parts manufactured in nickel-base, Inconel 718, alloy.

title: Behavioral aspects of Helicoverpa armigera in the cotton vegetative phase1

description: ABSTRACT Helicoverpa armigera (Hübner) is part of an important complex of insects-pests that attack the cotton crop. This study aimed to identify the preferential plant parts for the oviposition of moths, as well as the movement and feeding behavior of caterpillars, in the vegetative phase of the cotton cultivar BRS 369 RF. Plants emitting floral buds were used to study the oviposition behavior of moths. For this, a completely randomized design, with three treatments (adaxial and abaxial sides of the leaf and floral buds) and twenty replications (plants in pots), was used. In order to evaluate the behavior of the caterpillars in the cotton vegetative phase, another 3 × 5 factorial design, with nine replications, was used. The treatments were three ages (first, second and third instars) combined with five behaviors (walking, resting, waving, eating and drop-off). In this trial, the period of the day when caterpillars are more active was also evaluated. It was observed that H. armigera moths prefer to lay their eggs on the adaxial leaf side and on the last two nodes of the plant, in a descending direction. The adaxial leaf side is also the part of the plant preferred by caterpillars for walking, eating and resting, being this last behavior the most frequent in all instars. In general, the caterpillars walk more in the morning.

title: Bedrooms of contemporary children: the construction of a new object of research

description: Abstract This article seeks to describe how the change of the spaces reserved for children in the residential architecture has generated a new object of study that has been named as bedroom culture. If the empirical object is new in the childhood studies field, the theoretical issues are frequently the deployment of diverse aspects of the material culture. Therefore, this paper has elected three main issues: the concept of material culture of childhood, the use of the notion of space in academic research, and, finally, the relationship between subjects (children in this case) and objects.

title: Gas exchanges and growth of passion fruit seedlings under salt stress and hydrogen peroxide1

description: ABSTRACT The semi-arid region of the Brazilian Northeast has adequate edaphoclimatic conditions for the passion fruit production, but the water used for irrigation commonly has high concentrations of salts that are harmful to the plant growth and development. A previous supply of hydrogen peroxide induces the acclimation of plants under saline stress conditions, reducing deleterious effects on their growth and physiology. This study aimed to evaluate the gas exchanges and growth of passion fruit as a function of irrigation with saline water and exogenous application of hydrogen peroxide. The experiment was carried out under greenhouse conditions, using a randomized block design, in a 4 x 4 factorial arrangement, being four levels of irrigation water electrical conductivity (0.7 dS m-1, 1.4 dS m-1, 2.1 dS m-1 and 2.8 dS m-1) and four hydrogen peroxide concentrations (0 µM, 25 µM, 50 µM and 75 µM), with four replicates and two plants per plot. The hydrogen peroxide application attenuated the deleterious effects of the irrigation water salinity on transpiration, CO2 assimilation rate, internal carbon concentration, plant height and leaf area of yellow passion fruit, at 60 days after sowing, with the concentration of 25 µM being the most efficient. Irrigation using water with electrical conductivity above 0.7 dS m-1 negatively affects the gas exchanges and growth of passion fruit, being the stomatal conductance and leaf area the most sensitive variables to the salt stress.

title: Water retention capacity in Arenosols and Ferralsols in a semiarid area in the state of Bahia, Brazil

description: Abstract: One of the most serious problems in areas indicated for irrigation projects in the Brazilian Northeast region is the occurrence of sandy soils, known to have low moisture retention, but occurring in strategic locations in terms of water supply and geographical situation, and which can be used for agricultural purposes. The objective of this study was to evaluate the influence of particle size distribution and porosity on the water retention capacity of sandy soils in the semiarid area of the Northeast region. Soil bulk and particle densities, total porosity (macro, meso and microporosity), field capacity, permanent wilting point and soil-water retention curve were determined in samples of surface (A) and subsurface (C or Bw) horizons of ten sandy soil profiles. Particle size was determined subdividing the sand fraction into five classes. Higher amounts of the medium and fine sand fractions of the studied soils oriented their physical and hydric characteristics, being responsible for their great water retention. The arrangement of the fine silt, clay, fine sand and very fine sand particles may have provided a diversity of pore sizes and a good pore distribution, being responsible for the large proportion of micropores in the soils, allowing great water retention capacities.

title: Energy balance and CO2 emission in mechanized biomass harvesting in pine stands under thinning

description: Abstract: Biomass is an important component of the Brazilian energy matrix, with a potential contribution of co-products from thinned forests. The aim of this work was to evaluate the energy balance and CO2 potential emission in mechanized biomass harvesting operations in Pinus taeda stands at 9 and 10 years-old and under thinning, searching to support the use of co-product biomass from thinning as a renewable energy source. Thinning was carried out through cut-to-length harvesting method, in which large logs for sawmill and small logs for energy were produced. In addition, tops, needles, barks, and branches were considered as co-products. The balance between consumed energy and emitted CO2 by machines for thinning in relationship to the energy and CO2 in thinned biomass was estimated. Thus, dry matter, energy potential, and CO2 potential emission were evaluated and compared considering thinning stand ages as treatments. Mechanized thinning consumes a large energy and produces CO2, however, the energy consumed by machines is lower than 1% of the estimated energy potential in thinned biomass, while the CO2 emission is lower than 0.5% of the biomass. Therefore, the use of co-product biomass of thinning is an important way to mitigate greenhouse gas emission.

title: Kidney anatomy, histology and histometric traits associated to renosomatic index in Gymnotus inaequilabiatus (Gymnotiformes: Gymnotidae)

description: ABSTRACT The Gymnotus inaequilabiatus is a Neotropical fish widely distributed in marginal areas of bays. The aim of this study was to describe the main histological and histopathological traits in the head and exocrine kidney. Here, histometric and structural density techniques were associated with renosomatic index (RSI). The kidney was processed for light microscopy. Lipofuscin and hemosiderin content were visually estimated in the melonomacrophages centers (MMCs). All the biometric body variables were correlated with RSI, especially the kidney weight and gross lesions count. The general architecture of head and exocrine kidney was similar to that described for other teleost species. MMCs were prevalent in both portions and correlated with RSI in the head and exocrine kidney. Granulomatous structures were often observed in both portions; however, they were associated only in the exocrine kidney with RSI. Of all the structures hystometrically estimated, only proximal tubular diameter and thickness, and distal tubular thickness were correlated to renosomatic index. The RSI is an useful biometric variable that represent some physiological and morphological characteristics of kidney in G. inaequilabiatus. These findings may be used in future studies to evaluate the effects of environmental stressors on the renal adaptative physiological process.

title: Conditioning and coating of Urochloa brizantha seeds associated with inoculation of Bacillus subtilis1

description: ABSTRACT Technological advances for improving the sowing stage of forage plants are important because, besides increasing the operation efficiency, they may also positively affect the plant growth. This study aimed to evaluate the inoculation of Bacillus subtilis in Urochloa brizantha seeds, using coating, physiological conditioning and storage procedures, as well as to observe its effects on seed storage and plant growth. A completely randomized design, in a 2 × 3 × 5 + 1 factorial scheme [two inoculation procedures (coating and conditioning), three inoculants (B. subtilis AP-3, B. subtilis PRBS-1 and without bacteria), five storage periods (0, 30, 60, 90 and 120 days) and control (bare seeds)], with five replicates, was used. Two lots of U. brizantha seeds were used, characterized as being of higher and lower viability. After the treatments, part of the seeds was employed to evaluate the plant growth promotion in a greenhouse, during 180 days, while the remaining portion was stored at a temperature of 25 ºC, with the seed germination being evaluated every 30 days, for 120 days. The physiological conditioning showed the best performance in the evaluations carried out for U. brizantha seeds with B. subtilis. The coating and conditioning of the U. brizantha seeds with lower viability, both with and without the inoculation of bacteria, increases the shoot mass of plants after 180 days of growth.

title: Hôtel d'Alluye, Blois

description: "L'hôtel est édifié entre 1500 et 1508 pour Florimond Robertet, trésorier de France, secrétaire des rois Charles VIII, Louis XII et François Ier. Influencé par l'art italien du Quattrocento, Florimond Roberteret fait de son hôtel un manifeste de modernité tant sur le plan que sur le décor. De dimensions sans équivalent dans le centre de Blois, l'hôtel se compose à l'origine de quatre corps de bâtiments, précédés d'une galerie formant un péristyle autour d'une couur centrale. Au fil du temps, plus de la moitié de l'hôtel est détruit. Très restauré au 19e siècle, il reste une référence dans l'art de la première Renaissance"
