1. BEAK TRIMMING BY INFRARED RADIATION OF LAYERS
ABSTRACT This study aimed at evaluating beak-trimming methods and intensities on the performance, beak length and uniformity, and egg parameters of commercial layers. During the rearing period, birds were distributed in randomized blocks, with a 2x3 factorial design + two treatments, consisting of beak trimming with infrared (IR) radiation (moderate or sever

3. Study on Preparation and Performance of High Swelling Bentonite
ABSTRACT For improving the expansibility of natural Ca-based bentonite (Ca-Bent), the Ca-Bent was modified with sodium dodecyl benzene sulfonate(SDBS)-Na2CO3 complex agent by microwave semi-dry method. And the ratio of Na2CO3 to SDBS, microwave power, radiation time and initial temperature on the modification were studied. Furthermore, X-ray diffraction (XRD

4. Síntesis y caracterización de “tanatos” de lantano como inhibidores de la corrosión
ABSTRACT Tannins are polyphenols synthesized by plants. They are found in Quebracho (Schinopsis Balansae) wood, Tara (Caesalpinia spinosa) fruits, etc. They have been incorporated in the coating industry as "antifouling" agents and as corrosion inhibitors in acidic solutions. Moreover, lanthanum solutions have a great inhibitory effect over SAE 1010 steel co

5. Structural, Optical and Thermal Characterizations of PVA/MAA:EA Polyblend Films
Films of polyvinyl alcohol (PVA), Methacrylic Acid - Ethyl Acrylate (MAA:EA) copolymer and their blends PVA:MAA:EA of composition 80:20, 60:40, 50:50, 40:60, 20:80 (wt %) were prepared by using the solution cast technique. The prepared films were investigated by structural, optical and thermal studies. X-ray diffraction (XRD) scans revealed the semicrystalli

6. Effect of compatibiliser on the properties of polypropylene/glass fibre/nanoclay composites
Abstract Glass fibre (GF), nanoclay (NC) and hybrid composites compatibilised with maleic anhydride polypropylene (MAPP) were prepared by extrusion and injection moulding. The fourier transform infra-red spectra revealed the characteristic absorption peaks of MAPP in the compatibilised GF and NC composites. A decrement in the peak intensity of X-ray diffrac

7. The structural modification of cassava starch using a saline water pretreatment
Abstract The cassava has been modified successfully by using the saline water, which was abundantly available on the planet. The biomass was submerged in saline waters that salt concentrations were altered at 0, 3.5 percent (seawater) and 10 percent (w/w) and were kept 5 days. After recovery by washing steps, the treated solids were characterized by using X

8. Experimental Multi-scale analysis of Carbon/Epoxy Composites Nano-Reinforced by Carbon Nanotubes/Multi-layer Graphene
Nano-size structures, nanotubes/multi-layer graphene (CNT/MLG), were dispersed into epoxy system by a combination of sonication and high shear mixing. To avoid CNT/MLG agglomeration, a non-covalent functionalization were performed using surfactants, CO890 - Polyoxyethylene (40) nonylphenyl ether and SDBS - sodium dodecyl benzene sulfonate. Raman spectroscopy

9. SELECTIVE SYNTHESIS OF PEG-MONOESTER USING CESIUM HETEROPOLY ACID AS HETEROGENEOUS CATALYST
Esterification of oleic acid with polyethylene glycol 600 (PEG-600) to produce polyethylene glycol monooleate (PEG-monooleate) and polyethylene glycol dioleate (PEG-dioleate) as by-product has been studied in the presence of heterogeneous acid catalysts, i.e. cesium heteropoly acid (Cs HPA). The results are compared with those obtained from a classical homog

10. Trocas gasosas em feijão-caupi e efluxo de CO2 do solo irrigado com água salina
RESUMO As trocas gasosas em plantas e a respiração do solo são ferramentas importantes para avaliar os efeitos da salinidade no sistema solo-planta. Com este propósito conduziu-se um experimento com feijão-caupi irrigado com seis níveis de condutividade elétrica (0; 2,5; 5,0; 7,5; 10,0 e 12,5 dS m-1) elaborados com duas fontes: NaCl e uma mistura de �

12. SEPARAÇÃO DE TEMPERATURA E EMISSIVIDADE A PARTIR DE IMAGENS DO INFRAVERMELHO TERMAL: ANÁLISE DE SUAS APLICAÇÕES/RESTRIÇÕES
O infravermelho termal (TIR - ThermalInfraRed) é uma porção do espectro eletromagnético com várias aplicações no Sensoriamento Remoto, tais como: geologia, climatologia, análises de processos biológicos, análises geofísicos, avaliação de desastres e detecção de mudanças, entre outras. No TIR a emissão de radiação dos alvos é dominante, co
