25. Modelo de predicción de la deserción estudiantil de primer año en la Universidad Bernardo O´Higgins
Abstract The objective of this study is to model a retention predictive system for first-year students at Universidad Bernardo O’Higgins (Santiago de Chile), by determining which of the variables of entry into higher education, whether these are academic, social or relatives, are revealed significant for this analysis. The construction of the research mode

26. Temporal Variation of Soil Physical Quality under Conventional and No-Till Systems
ABSTRACT: Determination of soil physical quality (SPQ) is very important because it is related to many important soil processes. However, it is not clear which indicators should be considered in this evaluation, and information about temporal variation of SPQ under different soil tillage systems is scarce. The aim of this study was to determine the effects o

27. Can intra-radicular cleaning protocols increase the retention of fiberglass posts? A systematic review
Abstract The presence of residues within the root canal after post-space preparation can influence the bond strength between resin cement and root dentin when using fiberglass posts (FGPs). Currently, there is no consensus in the literature regarding what is the best solution for the removal of debris after post-space preparation. This systematic review invo

28. Evaluation of membrane microfiltration fouling in landfill leachate treatment
ABSTRACT The membrane separation capacity allows the retention of the remaining organic matter that could not be removed by the biological process, increasing the treatment efficiency. The aim of this study was to evaluate the microfiltration (MF) process in a tertiary treatment system for landfill leachate from the Rincão das Flores, Caxias do Sul/RS/Brazi

30. Natural membranes of Hevea brasiliensis latex as delivery system for Casearia sylvestris leaf components
ABSTRACT Natural latex from Hevea brasiliensis (Wild. ex A.Juss) Müll.Arg., Euphorbiaceae, showed angiogenic action and Casearia sylvestris Sw., Salicaceae, leaf derivatives presented anti-inflammatory and wound healing activities. Therefore, an association of these effects was interesting for wound healing applications. The aims of this study were the deve

31. Introducing care management to Brazil’s alcohol and substance use disorder population
Brazil has a sizable alcohol and substance use disorder (ASUD) population, yet there are considerable gaps in treatment access and retention. ASUD, a chronic medical condition, is highly comorbid with medical and behavioral health disorders. This indicates a need for more targeted interventions in order to achieve health care integration (a major goal of Bra

32. HPLC-DAD DETERMINATION OF BERBERINE, CHELERYTHRINE AND SANGUINARINE IN THE MEXICAN PRICKLY POPPY (Argemone mexicana L. PAPAVERACEAE), A MEDICINAL PLANT
A sensitive, simple, rapid and reliable HPLC-DAD method for the analysis of the benzylisoquinoline alkaloids (BIA's) content in Argemone mexicana (Papaveraceae) is presented. This method allows the simultaneous separation and quantitation of berberine (Bn), chelerythrine (C) and sanguinarine (S) in extracts from A. mexicana tissues, reducing time of analysis

33. Dairy manure wastewater in serial UASB reactors for energy recovery and potential effluent reuse
Abstract This manuscript addresses the use of dairy manure wastewater (DMW) as a substrate for methane production in a high rate system - two serial UASB reactors - and the characterization of the effluent in the different phases of the treatment. Two experimental conditions were applied. In the first, the organic load rate (OLR) was 6.2 gCODtotal L-1 d-1 an

34. Promotion of cutaneous penetration of nifedipine for nanoemulsion
ABSTRACT This article reports the development and characterization of a nanoemulsion (NE) able to improve the cutaneous penetration of nifedipine. NE with nifedipine was development and characterized, presenting droplet size of 20 nm with low polydispersity index (IP<0.1), spherical shape without aggregation, pH compatible with typical skin levels and stabil

35. A Multi-Pumping Flow System with Pulsed Fluidization to Evaluate Soil Capacity for Phosphate Adsorption
Soils with high levels of iron and aluminum, thus negatively the phosphorous availability, affecting crop yields. A prior determination of the soil capacity to adsorb phosphate is relevant to attaining good agricultural performance. To this end, a multi-pumping flow system with pulsed fluidization is proposed. The procedure takes into account the amount of r

36. Liposomes as potential carriers for ketorolac ophthalmic delivery: formulation and stability issues
ABSTRACT Drug delivery to treat ocular disorders locally is a challenging endeavor. Traditional ocular dosage form - eye drops - exhibits poor availability, consequently inefficient therapeutic response. The objective of the study was to formulate and characterize a ketorolac tromethamine ocular system with a prolonged release pattern based on liposomes as a
