13. Development of a simple, rapid and validated spectrophotometric method for nitazoxanide in pharmaceutical formulations and comparison with HPLC
A rapid, economical, reproducible, and simple direct spectrophotometric method was developed and validated for the assay of nitazoxanide in pharmaceutical formulations. Nitazoxanide concentration was estimated in water at 345 nm and pH 4.5. The method was suitable and validated for specificity, linearity, precision, and accuracy. There was no interference of

14. An effective device for generating alginate microcapsules
An alternative approach to somatic gene therapy is to deliver the therapeutic protein by implanting genetically modified cells that could overexpress the gene of interest. Microencapsulation devices were designed to protect cells from host rejection and prevent the foreign cells from spreading while allowing protein secretion. Alginate microcapsules form a s

15. Preparation, characterization and evaluation of iron oxides and cobalt supported on activated carbon and polymeric catalysts for the dehydrogenation of ethylbenzene / Preparação, caracterização e avaliação de óxidos de ferro e cobalto suportados em carvão ativado polimérico como catalisador na reação de desidrogenação do etilbenzeno
In this work were synthesized catalysts supported on activated carbons, which were obtained by carbonization of a polymer matrix. The precursor of activated carbon was the sulfonated styrene-divinylbenzene copolymer, which was synthesized by suspension polymerization in the presence of inert diluents to produce a macroporous network structure. The chemical m

16. Uso do sensoriamento remoto orbital e de superfície para o estudo do comportamento espectral do corpo de água do reservatório de Manso, MT, Brasil / Use of orbital and surface remoto sensing to the study of the spectral signature of the reservoir water Body, MT, Brazil
The monitoring of water quality of a reservoir allows for preservation of the environment as well as bringing social-economic benefits. Remote Sensing accomplishes this monitoring in a synoptic way, because it considers spatial and time scales necessary to evaluate an aquatic ecosystem. For this, a Moderate Resolution Imaging Spectroradiometer (MODIS) sensor

17. Active system of auto-stabilization for suspended vehicles. / Sistema ativo de auto-estabilização para veículos suspensos.
During the last decades, many researches and studies have been done about suspended vehicles such as chair lifts, cable cars, carrying and assemblies of parts in the industry, etc. Suspended vehicles behave like a pendulum and they are susceptible to the action of external forces which cause oscillations and unwanted swing at the vehicle that may affect func

18. Active magnetic bearing applied to a tubular linear induction motor. / Mancal magnético ativo aplicado a um motor de indução linear tubular.
A tubular linear induction motor applied to onshore oil exploitation, named MATÆOS (which is in the Portuguese acronym for Tubular Asynchronous Motor for Onshore Oil Exploitation) was built at Escola Politécnica da Universidade de São Paulo (EPUSP). Its purpose is to directly drive the sucker-rod pump installed in the down hole of the oil well. In continu

19. Respostas da banana Prata Anã minimamente processada e conservada em solução de sacarose com polpa de maracujá / Responses of Banana Prata Anã Minimally Processed and Preserved in Sucrose Solution with Passion Fruit Pulp
The aim of this work was to adjust the flowchart of fresh-cut bananas stored in sucrose solution with passion fruit pulp, as well as to know about the physical changes, chemical, biochemical, and physiological and to determine the shelf life of minimally processed banana kept in the solution. The cooling of the raw material in a cold chamber at 12 C for 4 ho

21. Estado viável não cultivável em Salmonella enterica: indução, perfil de proteínas intracelulares e detecção de mRNA / Viable but nonculturable state in Salmonella enterica: induction, intracellular protein profile, and mRNA detection
The foodborne pathogen Salmonella spp. enters into a viable but nonculturable state (VBNC) in response to adverse environmental conditions. The presence of VBNC cells is a public health concern since it may be overlooked under standard routine laboratory procedure, resulting in improper assessment of contaminating pathogens in food. This work was done to inv

22. PurificaÃÃo, caracterizaÃÃo e determinaÃÃo de atividade coagulante da lectina de sementes de Moringa oleifera
Moringa oleifera is a tropical plant of great economic importance with several industrial and medicinal applications. Many parts of the plant are used and the seed extract is commonly employed for water purification to human consumption. Lectins are proteins or glycoproteins of nonimmune origin, which bind carbohydrates bioespecifically with agglutinant cell

23. Bioatividade e efeito residual de nanoformulações de nim sobre Spodoptera frugiperda (J.E. Smith) / Bioactivity and residual effect of neem nanoformulations to Spodoptera frugiperda (J.E. Smith)
Neem extracts were nanoformulated with several types of nanoparticles and polymers in a tentative to reduce the biodegradation of neem active compounds and improve their residual effect. These nanoformulations were tested against Spodoptera frugiperda and their efficacy compared to a commercial product. The polymers poly(-caprolactone) (PCL), poly(- hidroxib
