title: Composted slaughterhouse sludge as a substitute for chemical fertilizers in the cultures of lettuce (Lactuca sativa L.) and radish (Raphanus sativus L.)

description: Abstract Flotation sludge (FS) is produced in huge amounts at slaughterhouses in western Santa Catarina, Brazil. This waste is rich in plant nutrients and a valuable resource for soil amendments. Five FS composts were tested as a replacement for chemical fertilizers (QF), namely T1 (75% poultry manure (PM) and 25% sawdust (SD)); T2 (50% PM and 50% SD); T3 (25% PM and 75% SD); T4 (100% PM and 0% SD); and T5 (0% PM x 100% SD). For lettuce plants, treatments containing composted FS resulted in an increased number of leaves, leaf area and leaf fresh weight (LFW). T1 presented the best results with increases of 1.4 fold in LFW compared to plants supplemented with QF. T2 was the most effective treatment for radish with the best results of root fresh weight and root diameter. Although T4 had the highest nitrogen content, it did not present the best results in growth performance for lettuce or radish. The presence of higher proportions of SD in composts (25% for lettuce and 50% for radish) improved the physical characteristics of the soil and proved to be a more balanced compost.

title: Effectiveness of Arsenic Co-Precipitation with Fe-Al Hydroxides for Treatment of Contaminated Water

description: ABSTRACT Wastewater treatment is a challenging problem faced by the mining industry, especially when mine effluents include acid mine drainage with elevated arsenic levels. Iron (hydr)oxides are known to be effective in removal of As from wastewater, and although the resulting compounds are relatively unstable, the presence of structural Al enhances their stability, particularly under reducing conditions. The purpose of this study was to assess the effectiveness of Al-Fe (hydr)oxide co-precipitates for the removal of As from wastewater and to assess the chemical stability of the products. Different Al-Fe (hydr)oxides were synthesized at room temperature from ferrous and aluminum salts using three different Fe:Al molar ratios (1:0.0, 1:0.3, and 1:0.7) and aged for 90 days (sulfate experiments) or 120 days (chloride experiments) in the presence of arsenic. At the end of the aging periods, the precipitated sludges were dried and characterized in order to evaluate their stability and therefore potential As mobility. All treatments were effective in reducing As levels in the water to below 10 µg L-1, but the presence of Al impaired the effectiveness of the treatment. Aluminum decreased the chemical stability of the precipitated sludge and hence its ability to retain As under natural environmental conditions.

title: Development and parameter optimization of maize flat bread supplemented with asparagus bean flour

description: Abstract The purpose of this study was to develop maize flat bread supplemented with asparagus bean flour (ABF). Preliminary study was conducted for maximum supplementation of ABF on the basis of sensory attributes and it was found that 15% ABF can be supplemented. Further a composite flour containing 85% maize flour (MF) and 15% ABF was used for the preparation of flat bread. The effect of baking temperature (200 to 235 °C) and baking time [time 1 (surface 1) and time 2 (surface 2)] (70 to 120 sec) on product responses such as sensory characteristics (overall color, appearance, flavor, taste, mouth feel, overall acceptability), texture (shear value) and moisture content were studied. Results indicated that baking temperature and baking time had significant (p &lt; 0.05) positive effect on sensory characteristics and shear value, while significant (p &lt; 0.05) negative effect on moisture content. Numerical optimization resulted in baking temperature 225 °C, baking time 1 (120 sec) for surface 1 and time 2 (116 sec) for surface 2 to develop a flat bread with best quality.

title: Balance emissions and CO2 uptake in concrete structures: simulation based on the cement content and type

description: Abstract While the cement plant is considered one of the most polluting industry, responsible for about 5% of global CO2 emissions, the concrete has the potential to uptake this gas through the carbonation process, offset in part the emissions generated in its production. With the purpose to analyze this process, this study aims to evaluate emissions and CO2 uptake with cement content 300-580 kg produced with different cement types (CP II F, CP II E, CP II Z, CP III, CP IV and CP V). Through mathematical modeling, the emissions balance was made, identifying the mix that shows good resistance to carbonation and greater absorption of CO2 during the concrete life cycle. The results show that concrete with cement consumption between 380 and 420 kg/m³ showed better balance emissions.

title: A research on determination of quality characteristics of chicken burgers produced with transglutaminase supplementation

description: Abstract Transglutaminases are enzymes that catalyze the cross-linking between peptides or proteins. They play an important role in heat stability, gel-formation capability, water-holding capacity, emulsification and nutritional properties of proteins. They are preferred in the use of a variety of meat products due to the binding properties. In this study the effect of transglutaminase on the quality characteristics of chicken burgers were investigated. The enzyme was added at 5 different concentrations (0.2%, 0.4%, 0.6%, 0.8% and 1%) and the other treatments applied in burger production were followed. After the product was formed, it was left in the cold for a while and then analyses were carried out. According to the results, the enzyme contribution did not cause changes in the nutritional items (ash, fat, protein) of the product groups. However, there was a significant decrease in the cooking loss and a significant increase in the texture values in the groups in which the enzyme amount was increased. Although the texture of the products have been increased, the transglutaminase treatment did not effect sensory parameters of burgers compared to the control samples. Scanning Electron Microscopy (SEM) images also supported to the texture values of samples with the increase of cross-linking in microstructure.

title: Rhizobium strains selected from the Amazon region increase the yield of snap bean genotypes in protected cultivation

description: ABSTRACT Although the use of inoculants containing rhizobia is encouraged, there are no official recommendations for inoculation of snap bean. In this respect, the aim of this study was to evaluate the agronomic performance of Rhizobium strains in symbiosis with snap bean cultivars with different growth habits and crop cycles. The experiment was carried out in pots with soil in a greenhouse in the spring-summer season in Lavras, state of Minas Gerais, Brazil. A completely randomized experimental design was used, with 4 replications, in a 4 × 7 factorial arrangement involving four snap bean cultivars and seven treatments – five strains of Rhizobium (UFLA 02-100, UFLA 02-127, UFLA 04-173, CIAT 899, and PRF 81), plus two controls without inoculation (with and without 500 mg N-NH4NO3∙dm–3). We conclude that: i) while genetic differences were observed among cultivars with respect to nodulating capacity, in all cases significant benefits were observed from BNF inoculation and ii) inoculation with selected strains of Rhizobium, as well as fertilization with mineral N, favors plant growtht, snap bean yields, and accumulation of N in the pods and, therefore, can fully substitute nitrogen fertilization in snap bean grown under protected cultivation.

title: Hemolysis and Inflammatory Response to Extracorporeal Circulation during On-Pump CABG: Comparison between Roller and Centrifugal Pump Systems

description: Abstract Objective: To compare the perioperative incidence rates of hemolysis and inflammatory response in patients undergoing coronary artery bypass grafting with the two main types of cardiopulmonary bypass, centrifugal and roller pumps, and establish correlations among hemolytic and inflammatory changes. Methods: This was a prospective, randomized trial of 60 patients assigned to either roller pump (G1, n=30) or centrifugal pump (G2, n=30) bypass. Markers of hemolysis (serum haptoglobin, lactate dehydrogenase [LDH]) and inflammation (interleukin [IL]1ß, IL-6, and TNF-α) were measured and analyzed. Results: There was no significant between-group difference in the variables of interest. In G1, there was a positive association with IL-6 and TNF-α (P&lt;0.01 and P&lt;0.05, respectively). In G2, there was a positive association with LDH in the postoperative period (P&lt;0.5). At 24h post-cardiopulmonary bypass, there were positive associations between LDH and IL-1ß (P&lt;0.05), LDH and TNF-α (P&lt;0.01), haptoglobin and TNF-α (P&lt;0.05), and LDH and TNF-α (P&lt;0.01) in G1, and between LDH and IL-6 (P&lt;0.01), LDH and TNF-α (P&lt;0.01), and LDH and IL-6 (P&lt;0.01) in G2. Conclusion: There were no significant between-group differences in markers of hemolysis or inflammation. IL-6 and TNF-α were positively associated with duration of cardiopulmonary bypass in G1, while LDH was positively associated with duration of cardiopulmonary bypass in G2. The rate of significant associations between markers of hemolysis and inflammation was higher in the roller pump group (G1). Registration number: ReBEC (RBR-92b9dg).

title: Study of design methodologies of steel column bases

description: Abstract The behavior of a steel structure is directly related to the type of base used in the columns, which is essential to the stability and security of the structural system. The Brazilian standard ABNT NBR 8800:2008 does not directly covers this subject. Another Brazilian standard, ABNT NBR 16239:2013, presents a limited design procedure to hollow columns. In this paper, two design methodologies are presented considering the uniform and triangular pressure distribution between the base plate and the concrete surface. A computational program has been developed to design steel column bases considering both methodologies mentioned. The program has been validated with manually solved design examples and conclusions about the pressure distribution design procedures were made from the 200 bases designed by the program. It was noted that, for the triangular pressure distribution, there is an interval in which the procedure is not completely applicable. Apart from this interval, there was no significant difference in the results.

title: Characteristics and enhanced antioxidant activity of glycated Morchella esculenta protein isolate

description: Abstract Morchella esculenta (L) Pers. is a highly valued edible and medicinal fungus that remains underutilized. For this study, the effects of glycation treatment on antioxidant activity and characteristics of the M. esculenta protein isolate (MPI) were investigated via the Maillard reaction. Conjugation between MPI and xylose was proven via UV-vis, FT-IR, intrinsic fluorescence analysis, and SDS-PAGE. Amino acid analysis revealed involvement of lysine, arginine and tyrosine in MPI, forming a covalent cross-link with xylose. Differential scanning calorimetry (DSC) results showed that glycated MPI (MPIG) possesses a more favorable thermal stability compared to native MPI (MPIN), heated MPI (MPIH) and an unheated mixture of MPI and xylose (MPI-XM). MPIG exhibited significantly enhanced antioxidant activity compared to MPIN, MPIH, and MPI-XM. These results indicate MPIG can serve as a promising novel source of nutraceutical and functional ingredients that exert antioxidant activity.
