1. Preparation and performance of magnetic zirconium-iron oxide nanoparticles loaded on palygorskite in the adsorption of phosphate from water
Magnetic zirconium-iron oxide nanoparticles loaded on palygorskite as a low-cost adsorbent was produced by one-step co precipitation technique and its properties for phosphate adsorption were overall investigated. The Brunauer Emmett Teller (BET) specific surface area analysis, scanning electron microscopy (SEM), thermo gravimetric analysis (TGA), Fourier tr

2. Intrafollicular barriers and cellular interactions during ovarian follicle development
Abstract Follicles are composed of different interdependent cell types including oocytes, cumulus, granulosa, and theca cells. Follicular cells and oocytes exchange signaling molecules from the beginning of the development of the primordial follicles until the moment of ovulation. The follicular structure transforms during folliculogenesis; barriers form bet

3. Hydrogen production from aqueous glycerol using titanate nanotubes decorated with Au nanoparticles as photocatalysts
Abstract: Protonated titanate nanotubes (HTiNts) were synthesized using the hydrothermal method, followed by proton exchange with acid. Gold nanoparticles decorated titanate nanotubes (AuHTiNts) were obtained by the reduction of AuCl4- under vigorous stirring with an aqueous solution of HTiNts containing 1 wt% of ascorbic acid. To investigate the surface str

5. Elevated atmospheric CO2 concentration improves water use efficiency and growth of a widespread Cerrado tree species even under soil water deficit
ABSTRACT Changes in atmospheric CO2 levels are accompanied by ecological interactions involving other environmental factors, such as drought, which can severely alter the water balance of plants, thereby influencing sap flow, gas exchange, and plant growth. The objective of this study was to evaluate the water use economy, leaf gas exchange, and growth of yo

7. Textual Artifact of Advertising: A Thrust of Halliday’s Mood System Resources
RESUMO Este artigo argumenta que a publicidade contém uma variedade de textos que terminologias teóricas são capazes de exemplificar. Assim, dez propagandas de bebidas, entre outros tipos, foram escolhidas para análise. Os recursos de mudança de tom de Halliday decompuseram os textos em componentes significativos, que posteriormente foram tabulados com

9. Shifting habitat mosaic: identification and mapping
Resumo O Mosaico de Habitat Móvel (SHM) refere-se às mudanças temporais no padrão espacial dos habitats, através dos pulsos de inundação e seca. Este trabalho teve por objetivo mapear a dinâmica de um Mosaico Móvel associado aos pulsos de inundação e seca, na Área de Proteção Ambiental do Banhado Grande (APABG). A realização desta pesquisa di

10. Mapping Soil Cation Exchange Capacity in a Semiarid Region through Predictive Models and Covariates from Remote Sensing Data
ABSTRACT: Planning sustainable use of land resources requires reliable information about spatial distribution of soil physical and chemical properties related to environmental processes and ecosystemic functions. In this context, cation exchange capacity (CEC) is a fundamental soil quality indicator; however, it takes money and time to obtain this data. Alth

11. GAS EXCHANGE IN ‘POME’ BANANA PLANTS GROWN UNDER DIFFERENT IRRIGATION SYSTEMS
Abstract This study aimed to evaluate Pome type bananas grown under different irrigation systems. Seventy-two treatments were used in a factorial 3×2×12 scheme, where factors consisted of three irrigation systems (under-tree sprinkling, micro-sprinkling, and dripping), two cultivars (‘Prata-Anã‘ and ‘BRS Platina’), and twelve evaluation periods (m

12. BaltDC: purification, characterization and infrared spectroscopy of an antiplatelet DC protein isolated from Bothrops alternatus snake venom
Abstract Background: Snake venoms are a complex mixture of proteins, organic and inorganic compounds. Some of these proteins, enzymatic or non-enzymatic ones, are able to interact with platelet receptors, causing hemostatic disorders. The possible therapeutic potential of toxins with antiplatelet properties may arouse interest in the pharmacological areas.
