Few studies have focused on the effect that silicon fertilisation has on the incidence of brown rust in sugarcane, even though this crop is Si-accumulating and Si addition has been shown to have positive effects in other plant-pathosystems. The objective of this study was to quantify brown rust development in sugarcane after the addition of silicon fertilizer to texturally distinct soils over three sugarcane cropping cycles. One experiment was conducted for three years with sugarcane grown in 100 ...

The Institute for Transuranium Elements (ITU) is building up an accurate database of actinide behavior in chloride melts in support of its nuclear fuel reprocessing development program. The electrochemical properties of uranium, dissolved in LiCl-KCl eutectic melt, were investigated by transient electrochemical techniques, such as cyclic voltammetry (CV) and chronopotentiometry on an inert tungsten electrode. It was shown that is reduced to by a two-step mechanism corresponding to and transitions. ...

The objective of this study was to evaluate dietary lycopene levels on the immune responses of finishing pigs. Forty barrows and 40 gilts, averaging 75.04 ± 1.6 kg of initial weight, were allotted in a randomised blocks design arranged in a 2 × 5 factorial scheme, consisting of two sexes (males and females) and five lycopene levels (0, 12.5, 25.0, 37.5, 50.0 mg/kg of diet). The studied parameters were submitted to the statistical analysis adopting 5% significance. Increasing lycopene in pig diets increased ...

Foamy viruses naturally infect a wide range of mammals, including Old World (OWP) and New World primates (NWP), which are collectively called simian foamy viruses (SFV). While NWP species in Central and South America are highly diverse, only SFV from captive marmoset, spider monkey, and squirrel monkey have been genetically characterized and the molecular epidemiology of SFV infection in NWPs remains unknown. We tested a large collection of genomic DNA (n = 332) comprising 14 genera of NWP species for ...

Establishing the genetic basis that underlies craniofacial variability in natural populations is one of the main topics of evolutionary and developmental studies. One of the genes associated with mammal craniofacial variability is RUNX2, and in the present study we investigated the association between craniofacial length and width and RUNX2 across New World bats (Phyllostomidae) and primates (Catarrhini and Platyrrhini). Our results showed contrasting patterns of association between the glutamate/ ...

In the oil extraction process, drilling fluids can create a thin layer on the walls of the oil well known as filter cake. Its removal is essential for proper cementation between the coating and the rock formation. In this work, microemulsion systems based on produced water were formulated containing nonionic surfactants of different degrees of ethoxylation for cleaning the plaster of olefin-based drilling fluid. An experimental planning of Scheffé net was carried out showing the total efficiency ...

The impregnation of oil on solid surfaces is a major challenge currently due to the need to purify environments affected by disasters and accidents related to the oil and gas industry. In this work, microemulsion systems without oil phase were formulated containing nonionic surfactants of different degrees of ethoxylation (10, 8 and 6 ethoxylation bonds) for the solid-liquid extraction of heavy oil impregnated in sandstone rocks. A central composite design was carried out showing the total oil extraction ...

Abstract After drilling oil wells using oil-based drilling fluid, there is the occurrence of a formation of a thin layer of solids adsorbed on the surface, called filter cake, which must be removed to obtain satisfactory well cementation. The present work developed microemulsion systems from sodium dodecyl sulfate, a biodegradable surfactant, with kerosene as oil phase, n-butanol as cosurfactant and distilled water, in order to evaluate its efficiency in removing the filter cake. The results showed ...

OBJECTIVE: To compare the frictional resistance between self-ligating and conventional brackets tied to different types of wire. MATERIAL AND METHODS : Abzil Kirium Capelozza (Pattern I) and Easy Clip (Roth prescription) incisor brackets were used. An elastomeric ligature or a ligating wire 0.10-in was used to ligate the wire to the Abzil bracket. Three types of orthodontic archwire alloys were assessed: 0.016-in NiTi wire, 0.016 x 0.021-in NiTi wire and 0.019 x 0.025-in steel wire. Ten observations ...

Abstract The taxonomy of muriquis, the largest extant primates in the New World, is controversial. While some specialists argue for a monotypic genus ( Brachyteles arachnoides ), others favor a two‐species classification, splitting northern muriquis ( Brachyteles hypoxanthus ) from southern muriquis ( B. arachnoides ). This uncertainty affects how we study the differences between these highly endangered and charismatic primates, as well as the design of more effective conservation programs. To address this issue, ...

The use of surfactants in Enhanced Oil Recovery (EOR) projects has been extensively studied. The process of adsorption of these substances in the reservoir rocks is strictly important, since it provides a change in their wettability, allowing an increase in the oil recovery factor. However, the understanding of how the adsorption of surfactants occurs and the main phenomena involved in this process is still widely discussed. Thus, the objective of this work is to investigate and elucidate the adsorption ...

Ca isotopic compositions of Marinoan post-glacial carbonate successions in Brazil and NW Canada were measured. Both basal dolostones display δ44/40Ca values between 1 and 0.7‰, overlying limestones show a negative Ca isotope excursion to values around 0.1‰, and δ44/40Ca values rapidly increase up-section to near 2.0‰. In the Brazilian successions, those high δ44/40Ca values rapidly decrease and stabilize to values between 0.6 and 0.9‰. These Ca isotope secular variation trends are unlike those of ...

The record of pre-Quaternary travertines is restricted to relatively few publications in the geological literature. In this paper, the authors present a petrographic and geochemical study of Paleocene travertines partly exposed in the Itaboraí basin, a small half-graben of southeastern Brazil. Travertine lithofacies were defined mainly from borehole samples, and these data were integrated with available field information. The most representative lithofacies of the travertine system are crystalline ...
