1. Método da espectroscopia no infravermelho para análise dos soros de queijos de minas padrão e prato
An electronic equipment based on the infrared spectroscopy was evaluated to measure the whey composition in "Minas padrão" and "prato" cheeses. The results for fat, protein, and total solids using infrared instrument based on filters and using standard methods were compared. There were differences between the values obtained from both analytical methods, an

2. Uncooled detectors of continuum terahertz radiation
THz continuum spectral photometry has new and unique applications in different civil and military areas presenting a number of distinctive advantages on the well known microwaves or mid- to near-infrared technologies. THz sensing is essential to investigate the emission mechanisms by high energy particle acceleration processes. Technical challenges appear to

3. Caracterização de membranas de poliamida 66 preparadas pelo método de inversão de fases
In the present study, polyamide 66 (PA 66) membranes were prepared by phase inversion (PI) and characterized in order to verify their potential application in separation processes. PA 66 membranes were prepared using two different solvents, formic acid (FA) and chloridric acid (HCl), and water as a non-solvent. Membranes prepared in film form (not supported)

4. Evaluation of blood compatibility of plasma deposited heparin-like films and SF6 plasma treated surfaces
In devices used in open-heart surgery and dialysis, blood must be continuously processed using extracorporeal circuits composed of peristaltic pumps and active components such as specific filters and oxygenators. Several procedures have been employed to avoid blood coagulation induced by contact with the artificial surfaces of such devices. Often heparin, a

5. Synthesis of nanostructured boron nitride and its potentially for application in cosmetology / Sínteses e caracterização de nitreto de boro nanoestrutrado com potencialidade de aplicação em cosmetologia
Regular use of appropriate cosmetics is an important resource for the maintenance of the skin health and, consequently, its beauty. The effect of ultraviolet rays is harmful to the health of the skin and can result in increase of the cancer incidence, aging and other undesirable cutaneous changes. The effects of the infra-red rays are less described in the s

6. Carreador lipÃdico nanoestruturado à base de cera de carnaÃba: desenvolvimento, caracterizaÃÃo e uso na encapsulaÃÃo de benzofenona-3
Solid lipid nanoparticles made of pure lipids (SLN) or a mixture of solid and liquid lipids (NLC) have been proposed as a category of carriers for cosmetic ingredients of current and growing interest due to a number of advantages compared to conventional formulations. Natural waxes are considered lipid matrices of great potential for the production of topica

7. Compostos de Cério como Redutores de Fuligem no Uso de Biodiesel como Combustível / Compostos de cério como redutores de fuligem no uso de biodiesel como combustível
In the work, the complex Ce(hdacac)6·xH2O (x0-2) was synthesized in order to produce an additive capable of reducing soot, that is emitted from the combustion of diesel, biodiesel and its mixtures in compression engines. The complexes were produced from a new ligand, 3-hexadecylpentane-2,4-dione (hdacac), that has a long alkyl chain and two carbonyl groups

9. Sb doping effects and oxygen adsorption in SnO2 thin films deposited via sol-gel
Transparent electrically conducting antimony-doped SnO2 thin films have been prepared by sol-gel dip-coating process from colloidal aqueous suspension. The effect of doping content on the structural, optical and electrical properties is analyzed. Results from infrared optical transmission and reflection have shown that the higher the Sb concentration the low

10. The use of aerial videography in the detection of areas with nutricional deficiency in eucalyptus plantation. / Utilização da videografia aérea na detecção de áreas com deficiências nutricionais em plantios de eucalipto.
The aerial videography is a technique that has been used in the USA to evaluate, detect and prevent agricultural problems, as well as in the handling of natural areas. One of the reasons for the employment of this technique is its low cost for obtaining the images and the speed with that they can be captured, processed and analyzed. The aim of this work was
