25. Estudo de argamassas com agregados reciclados contaminados por gesso de construção. / A study on mortars produced with CDW recycled aggregates containing cypsum plaster as impurity.
This is an abstract of a Master of Science project carried out at EPUSP, Universidade de São Paulo, Brazil, aimed at investigating the effects of the use of recycled aggregates contaminated by small contents of gypsum plaster on masonry mortars. In the presence of moisture and by the action of gypsum minerals or other more complex ones that may occur, there

26. Desenvolvimento de plastico biodegradavel a base de amido de milho e gelatina pelo processo de extrusão : avaliação das propriedades mecanicas, termicas e de barreira / Development of a biodegradable plastic base of cornstarch and gelatin by the process of extrusion: evaluation of mechanical properties, thermal and barrier
Due to the increasing accumulation of synthetic plastic rubbish, damaging the ecosystem, various strategies are being followed aimed at decreasing this aggression by way of prevention, reduction, recycling and chemical valorization of the synthetic materials, and especially by the use of biodegradable polymers. The use of starch to make thermoplastic materia

27. Effect of clarithromycin on sputum production and its rheological properties in chronic respiratory tract infections.
Macrolide antibiotics possess a variety of actions other than antimicrobial activities. To determine the effects of long-term administration of clarithromycin (CAM) on the amount and physical properties of sputum in patients with clinical conditions associated with excessive airway secretions, we conducted the present study in a parallel, double-blind, place

28. In vivo effects of recombinant human DNase I on sputum in patients with cystic fibrosis.
BACKGROUND: Viscoelastic secretions in cystic fibrosis cause impaired mucus clearance and persistence of bacteria within the lung. The abnormal rheology is partly due to the presence of high molecular weight deoxyribonucleic acid (DNA). Recombinant human DNase I (rhDNase) has been shown to depolymerise DNA and thereby reduce the in vitro viscoelasticity of s

29. Viscoelastic evaluation of topical creams containing microcrystalline cellulose/sodium carboxymethyl cellulose as stabilizer
The purpose of this study was to examine the viscoelastic properties of topical creams containing various concentrations of microcrystalline cellulose and sodium carboxymethyl cellulose (Avicel® CL-611) as a stabilizer. Avicel CL-611 was used at 4 different levels (1%, 2%, 4%, and 6% dispersion) to prepare topical creams, and hydrocortisone acetate was used
