Finally, due to its high amount of reactive amorphous phase (about 73% for fraction size of 1400 μm) COBA is used, in combination with other by-products (coal fly ash and flue gas desulphurization residues), to stabilize municipal solid waste incinerator fly ash produced at the same incinerator plant, following the azure chemistry principle of use a waste to stabilize another waste.Integrated gasification combined cycle (IGCC) is a highly efficient method for producing electricity but discharges a byproduct in the form of a glassy slag, similar to other electricity generation operations. Several technologies for recycling IGCC slag have been developed thus far, although the results obtained are not promising or universally applicable. We quantitatively characterized an IGCC slag by using various testing methods, including an automated scanning electron microscopy-energy dispersive spectrometry (SEM-EDS) system, to recognize its potential for recycling. The IGCC slag did not contain free CaO, and the absence of free lime would address a concern of volumetric expansion during hydration. Automated SEM-EDS analysis revealed that approximately 98% of the IGCC slag particles consisted of calcium-rich aluminosilicate materials. Obvious differences in the concentrations of Si, Al, and Ca between the amorphous phases and the average chemical bulk were recognized. The chemical composition of the amorphous Si-Al-Ca phases was similar to that of Class C fly ash, while the average bulk composition of the IGCC slag was in between that of Class C and Class F fly ashes. Considering this discrepancy, understanding the dissolution mechanism of the reactive amorphous fraction as well as an exact assessment of the reaction products based on the role of Ca in alkali-activated materials provides a new approach for the valorization of IGCC slag.Waste tire rubber is produced on a large scale in the automotive industry and is considered difficult to recycle because they have iron, nylon, polyester, and chemical structure formed by cross-links. In this way, the waste is almost always deposited in inappropriate places or incorrectly burned, causing a series of environmental problems. The objective of this work was to analyze the viability of the use of waste tire rubber (5, 10, and 20% m/m) reinforced in polyurethane foam (PU) derived from castor oil to obtain composites, as an alternative for raw materials petrochemical industrial. The materials were characterized by scanning electron microscopy (SEM), optical microscopy (OM), apparent density, contact angle, water absorption, X-ray diffractometry (XRD), spectroscopy infrared (FTIR), thermogravimetry (TGA) techniques, and mechanical tests. The results showed that the residue of the rubber powder reinforced with polyurethane caused an increase in the density of the composites when compared to pure PU, which directly influenced the morphological, physical, thermal, and mechanical properties. This fact occurred because with the insertion of rubber powder in the PU there was a decrease in cell size and increase of pore volume. The TG and DTG analyzes showed that the insertion of the rubber powder improved the thermal stability of the composite when compared to pure PU, as well as impact tests and contact angle.Methyl mercaptan (MM) and dimethyl sulfide (DMS) are typical landfill odorous gases that have received little attention compared with hydrogen sulfide (H2S). In this study, landfill MM and DMS emissions were investigated regarding their origin from substrates with different sulfur states, namely, intrinsic organic sulfur and external inorganic sulfur (SO42-). Substrates with high protein contents showed the highest potential for MM and DMS emissions, at 46.0 and 9.2 μL·g-1 substrate, respectively. Meanwhile, a comparable contribution by SO42- was achieved when the SO42- content comprised over 40% of the substrate. The substrate contribution to DMS emission was up to 10 times the SO42- contribution. Meanwhile, the SO42- contribution to MM emission was over 1000 times that to DMS emissions. MM and DMS can accumulate in landfill sites and then be transformed into H2S or sulfide (S2-). This research offers a comprehensive understanding of MM and DMS emissions in landfill and provides a basis for classification management methods in landfill sites.In recent years, a growing number of investigations have examined food waste in the food service sector, in which the catering of individual events received little attention. We aimed to contribute to fill this knowledge gap by presenting insights from a case study based on data from 239 event caterings. The case study presents findings about the influences of four variables, namely event type, season, event size, and menu prices, on buffet leftovers. We used a waste tracking system that allowed kitchen staff to quantify buffet leftovers for 4 years from the beginning of 2014 until the end of 2017. Among the studied variables, the event size demonstrated the strongest influence on the generation of buffet leftovers in the case study. Buffet leftovers showed a trend of decreasing quantities relative to the number of guests for increasing event sizes. read more For instance, smaller events with less than 100 participants recorded the highest quantities of approximately 280 g of buffet leftovers per guest, and larger events of more than 500 participants recorded the lowest quantities of approximately 74 g per guest. In addition, we found that three food product groups-meat & poultry, finger food, and side dishes-caused approximately 54% of the overall quantity of buffet leftovers and approximately 65% of the corresponding monetary equivalents. Our findings emphasize that further research is necessary on food waste reduction strategies.
Pathologists encounter several challenges with programmed death ligand-1 (PD-L1) immunohistochemistry (IHC) tests in malignant effusions, including lineage specification (distinction between carcinoma vs. immune and mesothelial cells), background staining, sample fixation issues and inter-observer variability. We explored flow cytometric (FC) quantification of PD-L1 expression in malignant pleural effusions of lung adenocarcinoma patients as an alternative, automated, and objective quantification method compared to PD-L1 IHC.

We examined 23 malignant pleural effusions of TTF-1-positive adenocarcinoma were subjected to FC with a panel of antibodies against CD45, CD3, CD200, EpCAM, D2-40 (podoplanin), and PD-L1 (clone MIH1). The PD-L1 gate was established using fluorescence-minus-one (FMO) isotype controls. Lineage-specific PD-L1 surface expression was quantified and the FC tumor proportion score (TPS) was assessed. PD-L1 IHC was performed on cell block sections using Dako PD-L1 IHC 22C3 pharmDx assay and assessed by two cytopathologists blinded to the FC PD-L1 TPS.
