13. Manufacturing and characterization of sustainable macroporous glass foams
Abstract This work produced glass foams from soda-lime glass bottles, bentonite, and alumina by the replica method. Compositions with different contents of bentonite (5, 10, 15, and 20 wt%) were prepared and heat-treated at 800 °C. In the alumina-added compositions, 50 wt% of the bentonite was replaced by the alumina. The influences of the content of benton

14. Influence of the physical characteristics of sand and the crushed filler content on the properties of self-leveling mortars
Abstract The properties of self-leveling mortars (SLMs) in the fresh and hardened state are strongly affected by their formulation. In this study, the influence of three different quartz sands (different physical characteristics) was investigated in SLMs, as well as the replacement of these sands by crushed basalt filler. The tests performed were: spreading,

15. Evaluation of the properties of a foamed geopolymer developed with different types of metakaolin
Abstract The physical and mechanical properties of foamed geopolymers were determined. The geopolymers were made with two different metakaolins (from Metacaulim do Brasil - MB, and Pantano Grande/RS - MPG) as precursors, with NaOH and Na2SiO3 as activators, and with the addition of foam, which was produced with the foaming agent diethanolamide of coconut fat

16. Development and analysis of bread fortified with calcium extracted from chicken eggshells of Pakistani market
Abstract Calcium fortification is usually achieved by employing wheat flour as the most frequently used vehicle. In this study, potential of calcium extraction from chicken eggshell and its utilization as a bread fortificant in straight grade flour (SGF) is investigated. In addition, the fortified and unfortified (control) flour samples were evaluated for nu

17. PEACH PIT CHEMICALLY TREATED BIOMASS AS A BIOSORBENT FOR METFORMIN HYDROCHLORIDE REMOVAL: MODELING AND SORPTION MECHANISMS
ABSTRACT In this work, the potential of peach pit biosorption in the removal of the drug metformin hydrochloride from water is evaluated. Experiments are carried out in a closed batch system to evaluate the effect of the solution pH (2–10), temperature (25, 35 and 45 °C), stirring (100, 150 and 200 rpm) and chemical treatments. During the study, biosorben

18. Mucuna pruriens fiber: nutritional, functional and biological properties
Abstract An evaluation was done of the nutritional, functional and antioxidant properties of fiber residues from Mucuna pruriens bean. Nutritional value was quantified in terms of proximate composition, total dietary fiber (TDF), insoluble dietary fiber (IDF), soluble dietary fiber (SDF) and the Van Soest fiber components. Functional value was assayed by mea

19. Metal Distribution in the Environmental Compartments of Manguaba Lagoon (Alagoas State, Brazil)
The metal concentrations in water, sediments and mollusks (Tagelus plebeius) of the Manguaba Lagoon and the influence of humic substances from water and sediments in the distribution of these metals were investigated in this work. The mean metal concentrations in water were: Mg (89.0 ± 0.11), Ca (32.0 ± 0.10), Fe (0.97 ± 0.02), Mn (0.52 ± 0.01), Zn (0.33

20. Effects of passion fruit peel flour as a dietary fibre resource on biscuit quality
Abstract The purpose of this investigation was to evaluate the effects of the addition of passion fruit peel flour (PFPF) from two different species to biscuits. Each PFPF was added to biscuit flour in different amounts (wheat flour replacement rate: 0%, 5%, 10%, and 15%). The colour and textural properties of the doughs and biscuits were evaluated. The phys

21. SEQUENTIAL MULTI-ELEMENT DETERMINATION OF TRACE-METALS IN BIODIESEL SAMPLES USING HR-CS FAAS
In this work the feasibility of sequential multi-element determination of Zn, Fe, Mg, Cu, Na, K, Cr, Al and Ca in biodiesel samples by high-resolution continuum source flame atomic absorption spectrometry (HR-CS FAAS) was investigated. Biodiesel samples obtained from different sources and different chemical processes were analysed. The samples were diluted w

22. Physicochemical characterization, carotenoid content and protein digestibility of pumpkin access flours for food application
Abstract Pumpkin (Cucurbita maxima) research has been growing because of its characteristics, such as the attractive color, low-cost production, nutritional potential, and functional properties for food application. In this context, pumpkin processing for flour production provides a full possibility for the consumption of this vegetable, being thus an altern

23. Maximization of the use of casting sand residue in the production of fired ceramic bricks
Abstract In this study, a red ceramic was developed with the addition of sand residue from deburring and finishing processing of cast iron molds, replacing a variable fraction of the clay. The formulated masses were shaped by pressing and firing at different temperatures (850, 900 and 1000 ºC) at a heating rate of 180 ºC/h and 2-hour level. The bodies were

24. SOCIOLOGIA SAGRADA
Benzbromarone (BZB) is a drug that has diuretic activity and is used in the gout treatment. Its therapeutic efficiency is decreased by its low water solubility (11.8 mg L-1) and highly hydrophobic aspect (logP 2.7), which are responsible for affecting its intestinal absorption and bioavailability. BZB inclusion complex (IC) aims at increasing the drug solubi
