1. VALIDAÇÃO DE MÉTODO POR MEFS-HS/CG-EM PARA DETERMINAÇÃO DE CARBARIL EM PLASMA SANGUÍNEO
The aim this research is to develop a HS-SPME/GC-MS method to analyze the carbaryl in blood plasma samples of the rural workers, who live round the perimeter of Chapada do Apodi-CE. This was achieved by chromatographic signal of the 1-naftol, degradation product of carbaryl with the intention of evaluating the degree of exposure of the workers to pesticides,

2. The increase of surface area of a Brazilian palygorskite clay activated with sulfuric acid solutions using a factorial design
Palygorskite is fibrous clay in which the structural tetrahedral and octahedral layers are organized in a way that structural channels are formed, leading to high surface area. However, impurities inside the channels and aggregated ones considerably reduce the available area. In order to increase the surface area, an activation treatment can be considered us

3. Uma abordagem neurofisiológica da acetilcolina em plantas de milho hidratadas e sob condições de estresse hídrico / A neurophysiological approach to acetylcholine in maize plants hydrated and under water stress conditions
The occurrence of action potential and neurotransmitters, the major components of animal nervous system, in plants, bacteria and fungi, shows the universality of signaling principles and information transmission in the way of chemical and electrical signals in all organisms. These study topics, along with plant intelligence and vesicular-based auxin transpor

4. Feeding level and frequency for freshwater angelfish
The objective of this study was to determine the optimal feeding level and feeding frequency for the culture of freshwater angelfish (Pterophyllum scalare). A randomized block design in a factorial scheme (3 × 2) with three feeding levels (30, 60 and 90 g/kg of body weight (BW)/day) and two feeding frequencies (1x and 2x/day) was set up in duplicate, repres

5. Morphogenesis of dwarf elephant grass clones in response to intensity and frequency of defoliation in dry and rainy seasons
The aim of this study was to evaluate during the dry and rainy seasons the morphogenesis traits of two clones of dwarf elephant grass under different management strategies. The study was conducted in a factorial 2 × 2 × 3 design, using two clones, one green and one purple, two residual heights, 25 and 45 cm, and three frequencies of defoliation according t

6. Produção de gás de síntese a partir da glicerina / Syngas production from glycerol
Biodiesel (alkyls esters) is a clean burning fuel derived from renewable lipid feedstock such as vegetable oil or animal fat. Glycerin is a by-product from the biodiesel production which represents nearly 10% of product total mass. As the biodiesel production is increasing there exist incentives to use the glycerin as raw material for other processes. The gl

7. Fontes de fósforo na produção e composição bromatológica de cultivares de milheto forrageiro / Phosphorus sources in production and chemical composition of the peral millet forage
The dry matter yield and quality aspects of forage millet are still poorly understood, as well as specific information handled by this grass and nitrogen fertilization. Experiment was conducted to evaluate the productive potential and chemical composition of the dry mass of three cultivars of pearl millet (Pennisetum glaucum (L.) R. Brown) (ADR-7010, ADR- 50

8. Development of cosmetic moisturizer formulations and evaluation of hydrating efficacy by biophysical methods / Desenvolvimento de formulações cosméticas hidratantes e avaliação da eficácia por métodos biofísicos
Introduction: Hydration of the corneal layer varies according to the amount of water present; the transportation of water from the lower layers; evaporation speed and quantity and composition of epicutaneous emulsion. Proof of moisturizer formula efficiency must be prudent and analyzed using appropriate methods. Objective: The studys main objective was to as

9. DESENVOLVIMENTO INICIAL DE SANGUE-DE-DRAGÃO (Croton lechleri MÜLL. ARG.) SOB DIFERENTES CLASSES DE SOLOS, CORRETIVOS E NÍVEIS DE LUMINOSIDADE NA AMAZÔNIA CENTRAL / DESENVOLVIMENTO INICIAL DE SANGUE-DE-DRAGÃO (Croton lechleri MÜLL. ARG.) SOB DIFERENTES CLASSES DE SOLOS, CORRETIVOS E NÍVEIS DE LUMINOSIDADE NA AMAZÔNIA CENTRAL
The specie dragons blood (Croton lechleri) having been calling international attention due the presence of an alkaloid in its latex called taspine known for its antinflammatory, antibiotic and cicatrizing properties, being largely used in the healing of gastric ulcers, diarrhea and different types of viruses. The latex indiscriminated extraction from native

10. Analise da secagem de residuo de leite de soja "Okara" em secadores de leito de jorro e de cilindro rotativo assistido a microondas / Drying of soy milk residue in the spouted bed dryer and rotary cylindrical dryer assisted by microwaves
The use of industrial residues has become more and more important to avoid the environment contamination and to make use of resources considered wastes in the chemical and food industries. Actually, the approximated soy milk production in the world is unknown; however, it is known that large amounts of its residue, named "Okara", are generated by its product

11. Qualidade e decomposiÃÃo de materiais orgÃnicos presentes em propriedades rurais do semi-Ãrido / Quality and decomposition os organic materials found in farms of the semi-arid region of ne Brazil / Qualidade e decomposiÃÃo de materiais orgÃnicos presentes em propriedades rurais do semi-Ãrido / Quality and decomposition os organic materials found in farms of the semi-arid region of ne Brazil
Owners of small farms in the semi-arid region of NE Brazil usually do not use chemical fertilizers to ameliorate soil fertility. Therefore, the nutrients supply for their crops have to rely on soil organic matter mineralization or, in some cases, on the fertilization with animal manure (mostly from cattle or goats). However, the manure produced in these farm

12. Integrated crop-livestock and soil physical quality in Brazilian Cerrado / IntegraÃÃo Lavoura-PecuÃria e a Qualidade FÃsica do Solo na RegiÃo do Cerrado
Soil physics plays a fundamental role in conserving soil and water in agricultural landscapes and is also a key parameter for accessing the sustainability of agropastoral systems. Both pasture history and management can have a significant effect on soil physical attributes, but conclusive research on this subject remains fragmentary. This work aimed to quant
