Caracterização do intervalo hídrico ótimo de um latossolo roxo sob plantio direto

Soil physical attributes, i. e. , soil water potential, soil oxygen, and soil strength, directly affect plant growth. The least limiting water range (LLWR) is the range of soil water content within which plant growth is least limited by water potential, aeration and mechanical resistance and has not been evaluated in tropical soils. The objective of this research was to characterize the LLWR of a Typic Hapludox cropped to corn under no-tillage. Seventy-two undisturbed soil samples were collected at the crop row and interrow. The soil water retention curve and the soil resistance curve were evaluated in order to compute the LLWR. The results indicated that the LLWR varied positively with bulk density up to 1.1 Mg m-3 and negatively for higher densities. The LLWR ranged from 0.0073 to 0.1252 m3 m-3. Soil resistance to penetration was the limiting factor at the dry end of the LLWR in 85% of the samples while field capacity was the limiting factor at the wet end in 97%. Further studies on the LLWR in tropical soils would be relevant under a wide range in texture and management.

Temperature Distribution Induced by Pre-lgnition Reactions in a Rapid Compression Machine

Abstract The temperature after compression of reactive and unreactive gas mixtures are measured at different locations and times in a rapid compression machine by a thin wire thermocouple. Validation is done by laser Rayleigh scattering. Inspection or the temperature fields of unreactive gas and during the delays in three different patterns of spontaneous ignition of isooctane-“air” mixtures shows that the gas temperature is homogeneous for some limes after top dead centre. Then heat losses to the walls and gas recirculation induce temperature inhomogeneities. They are partially levelled as hot ignition is approached. The gas temperature before hot ignition is nearly the same and constant in time in both two-stage or one-stage ignitions. The levelling effect is attributed to the complex chemical kinetics of low temperature alkane oxidation in the range of the negative temperature coefficient of the global reaction rate.
Spatial and temporal variations of ambient PM 10 -bound polycyclic aromatic hydrocarbons in Chiang Mai and Lamphun Provinces, Thailand

Respirable airborne particulate matters (PM10) were collected using high volume air samplers for 24 h every three days from four sampling stations in Chiang Mai and Lamphun Provinces, Thailand. The maximum PM10 concentration for each sampling station ranged from 140 to 182 ug/m3. PM10-bound polycyclic aromatic hydrocarbons (PAHs) were extracted from quartz fiber filters and analysed by gas chromatography-mass spectrometry (GC-MS). Mean concentration of total PAHs was in a range from 1.7 to 12.2 ng/m3. Ratio of non-carcinogenic and carcinogenic PAHs found was approximately 1:3 or 1:4 depending on sampling sites. Concentrations of most of carcinogenic PAHs were found to be positively correlated to PM10 concentrations. Seasonal variation of PM10-bound PAHs was obviously seen in all sites. The highest concentration was found in dry season (December-March). Spatial variation was observed in one sampling site, where PAHs content was significantly higher than other sites. Apart from traffic congestion, this was .
Inaccurate Information in Marketplace Loans

Inaccuracy of borrower-provided information in marketplace loans for credit card debt repayment and consolidation contains information about credit risk. I identify inaccuracies based on three indicators: consistency of loan amount with outstanding credit balance, roundness of reported income, and roundness of chosen loan amount. An Inaccuracy Index constructed from these indicators has significant predictive power over the likelihood of default, and the additional default risk is not compensated by higher interest. Inaccurate information is more prevalent in areas with lower social capital, implying weaker social norms, among borrowers whose professions are considered less honest, and among borrowers with higher genuine income uncertainty.
Septate gallbladder in a dog with cholecystitis: A case report and literature review

A 5-year-old, Yorkshire terrier was presented due to the acute onset of vomiting and diarrhoea. The imaging studies showed an abnormally separated gallbladder with a thickened wall, a tortuous common bile duct that contained hyperechoic materials. A cholecystectomy was performed because of the failure of the conservative management. The gallbladder was partially divided by a septum and communicated with the cystic duct. Histologically, the dog was diagnosed as having cholecystitis and choledochitis. To the author’s knowledge, this is the first clinical description of a symptomatic septate gallbladder in a dog. Although congenital gallbladder abnormalities are rare in animals, a septate gallbladder can predispose to an inflammatory biliary disease due to the abnormal bile flow.

An Operational Approach to Multi-Objective Optimization for Volt-VAr Control

Recent research has enabled the integration of traditional Volt-VAr Control (VVC) resources, such as capacitor banks and transformer tap changers, with Distributed Energy Resources (DERs), such as photo-voltaic sources and energy storage, in order to achieve various Volt-VAr Optimization (VVO) targets, such as Conservation Voltage Reduction (CVR), minimizing VAr flow at the transformer, minimizing grid losses, minimizing asset operations and more. When more than one target function can be optimized, the question of multi-objective optimization is raised. In this work, a general formulation of the multi-objective Volt-VAr Optimization problem is proposed. The applicability of various multi-optimization techniques is considered and the operational interpretation of these solutions is discussed. The methods are demonstrated using a simulation on a test feeder.
Fire-Sale Risk in the Leveraged Loan Market

Using detailed loan holding data of Collateralized Loan Obligations (CLOs), we document empirical evidence for systemic risk due to leverage constraints on CLOs. Constrained CLOs fire sell loans downgraded to CCC or below, and thus loans widely held by constrained CLOs experience temporarily lower prices. This instability is exacerbated over time. As the CLO market grows, each CLO's effort to diversify its portfolio leads to similarity in loan holdings among CLOs, such that their leverage constraint binds simultaneously. CLOs' overlapping loan holdings transform idiosyncratic credit risk of large borrowers to systemic risk in the leveraged loan market.
IL-17A in Ovarian Cancer

Ovarian cancer is the most common malignant disease leading to death among women. IL (interleukin)-17A is the most well-studied member of the IL-17 family, and has been demonstrated to play a critical role in host defenses against various microbial pathogens, as well as against tissue inflammation. T-helper (Th)17 cells that produce interleukin (IL)-17A are of particular importance, because IL-17A exerts a wide variety of biological functions, particularly related to inflammation and the resultant carcinogenesis, as well as immune suppression in patients with cancer, and IL-17A-targeted therapy has been proven to be effective in the treatment of some autoimmune diseases. The pathogenic features of Th17 and IL-17A cells in cancer are still controversial, and Th17 cells appear to promote disease progression, as well as be present in the vicinity of many types of malignant diseases. In cancer patients, MDSC (myeloid-derived suppressor cells), one of the major immunosuppressive immature cells, and VEGF (vascular endothelial growth factor) are reported to correlate each other and strongly connected to IL-17-driven inflammation and malnutrition. In the present review, the latest advances are presented about the basic features of IL-17A and Th17. The function of IL-17A has not been clarified especially in ovarian cancer. This review overview the basic features of IL-17A and the functions in ovarian cancer as well as in other malignant and non-malignant diseases. Increasing our understanding of the interactions between IL-17A and ovarian cancer could lead to new therapeutic strategies in oncology.

Considerations on the Kinetics of Froth Flotation of Ultrafine Coal Contained in Tailings

This article presents a kinetic evaluation of froth flotation of ultrafine coal contained in the tailings from a Colombian coal preparation plant. The plant utilizes a dense-medium cyclones and spirals circuit. The tailings contained material that was 63% finer than 14 µm. Flotation tests were performed with and without coal “promoters” (diesel oil or kerosene) to evaluate the kinetics of flotation of coal. It was found that flotation rates were higher when no promoter was added. Different kinetic models were evaluated for the flotation of the coal from the tailings, and it was found that the best fitted model was the classical first-order model.
Electron-Beam-Induced Conduction in Polystyrene

The carrier mobilities of PS were studied using a short-pulsed electron-beam. Even in the polymer with a π-electron system, no clear knee was observed in the induced charge signals at low applied fields. A logarithmic plot of the induced current versus time gives a knee at time Tr, which is thought to be the transit time of the carrier front between electrodes. Simple calculation by the formula µ=L/TrE gives an apparent carrier mobility µ of 2.5×10-5 for electrons and 1.2×10-5 cm2/Vsec for holes, at 293 K. These apparent mobilities are a little smaller than those (10-4–10-5 cm2/Vsec) estimated from the knee point of the induced charge signal at higher fields in previous reports. Thus the measured mobility is field-independent and increases with temperature with an activation energy of about 0.4 eV for both electrons and holes.
Energetic Constraints on the Intertropical Convergence Zone Position in the Observed Seasonal Cycle From Modern‐Era Retrospective Analysis for Research and Applications, Version 2 (MERRA‐2)

Idealized simulations show that the approximate colocation between the ITCZ and the energy flux equator (EFE), which holds on the annual and zonal average, breaks down on subseasonal timescales, as the Hadley cell develops a shallow return flow and negative gross moist stability (GMS). Here, we explore if similar mechanisms are seen in reanalysis data. In the zonal mean, a temporal offset exists between the ITCZ and the EFE as the ITCZ is retreating from the Northern to Southern Hemisphere and the Hadley cell transports energy northward across the equator despite a northward‐shifted ITCZ. At these times, the southern cell has a bottom‐heavy structure, with a distorted cell boundary and northward energy transport. In the Eastern Pacific, while bottom‐heavy structures exist throughout the year, the bottom heaviness is stronger in boreal fall, when GMS is negative, and SSTs are weak while their Laplacian is large and negative below the ITCZ.
Molecular Recognition of PNA-Containing Hybrids: Spontaneous Assembly of Helical Cyanine Dye Aggregates on PNA Templates

Symmetrical cyanine dyes containing benzothiazole groups have been shown to bind with high affinity to a variety of PNA-containing hybrids, including PNA/DNA duplexes, a PNA/PNA duplex, and a bisPNA/DNA triplex. Binding of a dicarbocyanine dye results in a 114 nm hypsochromic shift of the main visible absorption band. Circular dichroism spectropolarimetry reveals exciton coupling between multiple chromophores bound to the same PNA/DNA or PNA/PNA duplex, demonstrating binding of the dye as an aggregate. A continuous variations experiment indicates that the dye binds as a 6(±1):1 complex with a 12 base pair PNA/DNA duplex. The dye aggregate forms in a highly cooperative manner and exhibits a temperature-dependent self-assembly behavior which is independent of the PNA/DNA hybridization event. Experiments with mismatched and parallel duplexes demonstrate a strong preference for a continuous, antiparallel helix as a template on which to assemble the helical dye aggregate. Successful binding of the dye to the d.

HEAT‐INDUCED GELATION AND PROTEIN‐PROTEIN INTERACTION OF ACTOMYOSIN1

Natural actomyosin (NAM) and “crude” actomyosin formed gels yielding maximum strengths (from back extrusion force) at pH 5.0 and 5.5, respectively. At pH 6.0, NAM gels had a least protein concentration endpoint (LCE) value of 6 mg/ml. Gel strength increased exponentially with an increase of NAM concentration from 3.75–10 mg/ml. With constant time (30 min)-temperature heating, NAM gel forces increased by 20.5% (NS, P>0.05) in the 30–80°C range. Arrhenius plots of NAM interaction in solution and in gelation at pH 6.0 indicated two different reaction mechanisms within the temperature zones above and below approximately 35°C for solutions and 40°C for gels. Similarity of interaction slopes above the 35–40°C region suggested one reaction mechanism for NAM molecular aggregation in solution and gelation.
Applications of the electron backscatter diffraction technique to ceramic materials

A technique with a relatively high spatial resolution is required for an effective analysis of the microstructure of ceramic materials. The recently developed electron backscatter diffraction (EBSD) technique, which works within a scanning electron microscope, enables a spatially highly resolved study of crystallographic orientations while recording Kikuchi patterns on a user-defined grid. However, such an EBSD texture analysis was until now not often performed on ceramic materials – in contrary, the technique is widely employed in the analysis of metallic materials, including the investigation of various types of steels. The use of ceramics possesses a variety of problems for EBSD investigations like: (i) complicated crystal structure, (ii) difficult surface preparation, and (iii) problems arising from a low conductivity of the ceramic materials. Here, we discuss these problems and present solutions in order to obtain high-quality Kikuchi patterns from such ceramics.
9—THE INHERENT SKEWNESS OF THE 2/2 TWILL WEAVE

The geometry of the 2/2 twill is studied by reference to (a) an idealized cloth made of flexible and frictionless threads, and (b) a simpler model derived from this. The existence of interactions tending to disturb the model from a square configuration is shown and their magnitudes are related to the basic parameters. In the idealized cloth, these interactions produce an equilibrium configuration which is not square. The degree of skewness is related to the diameter and crimp of the threads and the influence of yarn stiffness and friction on the skewness in practical cloths is discussed.
Biosurfactant Producing Microbes and their Potential Applications: A Review

Biosurfactants are surface-active biomolecules produced by microbes (bacteria, fungi, and yeast) and have several advantages over the chemical surfactants, such as lower toxicity, higher biodegradability, better environmental compatibility, higher foaming, high selectivity, and specific activity under extreme conditions such as temperature, pH, and salinity. Almost all the surfactants now available in the market are chemically synthesized. Recently, attention toward the biosurfactants was doubled, which is mainly due to their wide range of functional properties and the diverse synthetic capabilities of the microbes. Microbial biosurfactants are found to have a wide range of applications in environmental protection, which include enhancing oil recovery, controlling oil spills, biodegradation, and detoxification of oil-contaminated industrial effluents and soils. Biosurfactants produced by microorganisms have potential applications in pharmaceutical/medicine, food, cosmetic, pesticide, oil, and biodegradation industries. In this review article, we concentrated on three important aspects such as various types of biosurfactants, the group of microbes involved in the production of biosurfactants, and application of microbial biosurfactants.
Hydrodynamics of Riser Units and Their Impact on FCC Operation

The hydrodynamic characteristics of the riser of a FCC plant are investigated in a cold pilot plant. The results are checked and completed with measurements made in real operating FCC units. In both cases, tracing of the gas, sampling probes, and γ-tomography were used. The gas and solid velocity profiles are described by using a plug-flow model with radial dispersion. The gas velocity profile is formally represented by an Ostwald−de Waele type equation. The axial solid concentration profile is fitted to data obtained in a commercial FCC unit. The radial dispersion coefficient of the gas is directly measured in the plant. The kinetics of the reactions occurring during catalytic cracking are investigated in a microreactor and are represented by a 19-lump model including deactivation by coking of the catalyst. A combination of this reaction model with the hydrodynamic model is able to predict with a good precision the yields of the different product families obtained in an industrial FCC unit. It is checked.
