1. Selective head cooling and whole body cooling as neuroprotective agents in severe perinatal asphyxia
RESUMO INTRODUÇÃO A possibilidade de a hipotermia ter um papel terapêutico durante ou após a reanimação da asfixia perinatal grave tem sido um foco de pesquisa de longa data. Estudos desenhados em torno desse fato mostraram que a hipotermia cerebral moderada, iniciada o mais cedo possível, tem sido associada à neuroproteção potente e duradoura em

2. Avaliação da resistência de união de uma cerâmica de óxido de zircônia submetida a tratamentos de superfície por abrasão
Resumo Introdução A cimentação adesiva, com cerâmicas puras, é um passo relevante no estabelecimento da longevidade de trabalhos protéticos, sendo estes os melhores materiais utilizados para a reposição de dentes perdidos, de forma a reabilitar o sorriso. O sistema cerâmico de zircônia não se beneficia do tratamento com ácidos e necessita de di

3. HOT AEROSOL FIRE EXTINGUISHING AGENTS AND THE ASSOCIATED TECHNOLOGIES: A REVIEW
Abstract Since the phase out of Halon extinguishers in the 1980s, hot aerosol fire suppression technology has gained much attention. Unlike traditional inert gas, foam, water mist and Halon fire suppression agents, hot aerosol fire extinguishing agents do not need to be driven out by pressurized gases and can extinguish class A, B, C, D and K fires at 30 to

4. Confiabilidade dos testes de condução nervosa; efeitos da crioterapia na condução nervosa sensorial e motora
This thesis presents three manuscripts derived of two research projects that were developed during the doctorate program. Project 1. Purpose: To determine the interand intra-rater reliability of nerve conduction studies (NCS) of superficial peroneal, sural and medial plantar nerves. Methods: Two raters performed the bilateral NCS twice in 20 healthy particip

5. Efeito dos extratos do albedo de Citrus sinensis, Lentinula edodes, Agaricus blazei e dos compostos orgânicos voláteis produzidos por Saccharomyces cerevisiae no controle da mancha preta dos citros / Effect of albedo extracts of Citrus sinensis, Lentinula edodes, Agaricus blazei and volatile organic compounds produced by Saccharomyces cerevisiae in the control of citrus black spot
The citrus black spot is a disease that restricts the export of Brazilian oranges to the countries in Europe. Except for Citrus aurantium and its hybrids, all other varieties are susceptible to the pathogen. Thus, there is great interest that this disease does not occur, since it is considered a quarantine A1 disease. Problems associated with the acquisition

6. Influência da adição da lama fina de aciaria a oxigênio nas características físicas e microestruturais de pelotas queimadas de minério de ferro
At the Brazilian steelmaking industry, the estimated annual production of steelmaking BOF sludge is about 230 thousand tons. The BOF sludge is a residue typical of oxygen steel mills. The main chemical and granulometric characteristics of the steelmaking BOF sludge are the following: about 30% of BOF thick sludge, with high metallic content and granulometry

7. Rheological characterization of chicory root (Cichorium intybus L.) inulin solution
Inulin is a polysaccharide frequently used as a sugar or fat replacer in the food industry, which offers the advantage of a functional effect similar to those of dietary fibers. By cooling or freezing an inulin concentrated solution, a more concentrated solution precipitates as a paste-like substance, while the liquid phase forms a diluted solution. In this

8. Tratamento de águas de refrigeração com peróxido de hidrogênio
Hydrogen peroxide and chlorine are compared as possible disinfectants for water-cooling circuits. To this purpose, samples taken from the cooling system of a steel making plant were treated (at 25ºC and pH values of 5.5 and 8.5) with varying amounts of the two oxidizing agents (0.0 mg/L, 2.0 mg/L and 6.0 mg/L). The results were evaluated through bacterial c

9. Estudo dos parametros fisico-quimicos envolvidos na formação de microcapsulas produzidas por coacervação complexa. / Study of the physical-chemical parameters in the microcapsules formation produced for complex coacervation.
Microencapsulation is a technology used as a potential tool in the protection of a product and the modulation of its core release. Currently, studies in the area of microparticles and controlled release are considerably advanced and a variety of techniques and products are available, among them differents processes for atomization (spray drying, spray coolin

10. Failure of Legionella pneumophila sensitivities to predict culture results from disinfectant-treated air-conditioning cooling towers.
The disinfection of cooling towers based on manufacturers' treatment protocols, as employed in units installed at various public gathering places in Dallas, Tex. (hotels, municipal auditorium), and at the city health department, was evaluated for effectiveness in controlling Legionella pneumophila and compared with previous laboratory studies. In specimens c

11. Survival of Frozen Mycoplasmas
Cooling to -70 C killed a higher percentage of Acholeplasma laidlawii and Mycoplasma mycoides var. capri cells than cooling to -20 C. However, to preserve cell viability for prolonged periods storage at -70 C was much more preferable. The percentage of cells surviving freezing could be increased by increasing the initial cell concentration or by the addition

12. Production of Respirable Vesicles Containing Live Legionella pneumophila Cells by Two Acanthamoeba spp.
Two Acanthamoeba species, fed at three temperatures, expelled vesicles containing living Legionella pneumophila cells. Vesicles ranged from 2.1 to 6.4 μm in diameter and theoretically could contain several hundred bacteria. Viable L. pneumophila cells were observed within vesicles which had been exposed to two cooling tower biocides for 24 h. Clusters of ba
