This study highlights the importance of mineralogical composition for potential carbon dioxide (CO2) capture and storage of mine waste materials. In particular, this study attempts to evaluate the role of mineral carbonation of sedimentary mine waste and their potential reutilization as supplementary cementitious material (SCM). Limestone and gold mine wastes were recovered from mine processing sites for their use as SCM in brick-making and for evaluation of potential carbon sequestration. Dominant minerals in the limestone mine waste were calcite and akermanite (calcium silicate) while the gold mine waste was dominated by illite (iron silicate) and chlorite-serpentine (magnesium silicate). Calcium oxide, CaO and silica, SiO2, were the highest composition in the limestone and gold mine waste, respectively, with maximum CO2 storage of between 7.17 and 61.37%. Greater potential for CO2 capture was observed for limestone mine waste as due to higher CaO content alongside magnesium oxide. Mineral carbonation of the limestone mine waste was accelerated at smaller particle size of less then  38 μm and at pH 10 as reflected by the greater carbonation efficiency. Reutilization of limestone mine waste as SCM in brick-making exhibited greater compressive strength and lower water absorption compared to the bricks made of gold mine waste. The gold mine waste is characterized as having high pozzolanic behaviour, resulting in lower carbonation potential. Therefore, it has been noticeable that limestone mine waste is a suitable feedstock for mineral carbonation process and could be reutilized as supplementary cementitious material for cement-based product. This would be beneficial in light of environmental conservation of mine waste materials and in support of sustainable use of resources for engineering construction purposes.The present study investigated the impacts of humic acid (HA) and surfactants (SDBS and CTAB), which were ubiquitously found in the aquatic environments, on the removal of Cr(VI) by the hydroxylated MWCNTs-OH. The results showed that MWCNTs-OH could remove Cr(VI) from aqueous solution via adsorption coupled with reduction, and the kinetics followed the pseudo-first-order model with the rate of 3.5 × 10-3 h-1. In the presence of anionic SDBS, the removal percentage of Cr(VI) was greatly inhibited because the hydrophobic interaction and π-π interaction between SDBS and MWCNTs-OH surfaces not only decreased the adsorption sites for Cr(VI) but also made the surfaces more negatively charged. On the contrary, the existence of cationic CTAB could lead to the surfaces more positively charged, which consequently enhance the electrostatic attraction between Cr(VI) and the surfaces as well as the removal of Cr(VI). Noticeably, the presence of HA could promote the removal of Cr(VI), which was attributed to the reduction of Cr(VI) by the adsorbed HA. The ESR spectra indicated the existence of π-type radicals in HA structure and conduction electrons in MWCNTs-OH, and then the π-π interaction between MWCNTs-OH and adsorbed HA possibly increase the electron-donating ability of HA. Moreover, the promotive effect of HA could be enhanced with the addition of Ca2+. This study was helpful for us to understand the role of MWCNTs-OH in controlling the fate of Cr(VI) when HA and surfactants were present.Evidence suggesting the association between the atmospheric particulate matter (PM) and health problems stress the need for the establishment of policies and actions aiming the improvement of air quality. As a start point, the knowledge of the main PM contributors is fundamental. Receptor models are frequently used for the identification and apportionment of local sources, nevertheless, some features of these models must be considered. For instance, whether the region has sources with similar chemical profiles and/or whether there is source temporal or spatial similarity, which can generate collinearity, affecting the sensibility of the models. In this work, it is presented some study of cases showing some strengths of the chemical mass balance model (CMB), such as to infer specific sources acting over specific locations in a same region, and its weaknesses for separating collinear sources. Besides, this work shows some study of cases reporting that the identification of specific PM markers (organic, inorganic, and crystallographic) and determined in the receptor samples can lead to better sources separation and improvements in the interpretation of the results using positive matrix factorization model. This work also highlights for the importance of the information provided by receptor models, in which should be carefully considered by the environmental agencies for decision-making concerning air quality management.OBJECTIVE At our institution, we actively perform aortic valve neocuspidization (AVNeo) for aortic valve stenosis (AS) with a small annulus. In this report, we aimed to evaluate the midterm outcome of AVNeo for AS with a small annulus. METHODS From February 2011 to May 2017, we performed AVNeo for AS with a small annulus in 34 patients. Their mean age was 77.0 ± 9.1 years. Preoperative transthoracic echocardiography (TTE) revealed a mean peak pressure gradient average of 84.2 ± 31.1 mmHg. The effective orifice area index (EOAi) was 0.45 ± 0.14 cm2/m2. The mean annulus diameter was 18.4 ± 1.1 mm. Our procedure complies with the three cuspid suturing to the aortic annulus with glutaraldehyde-treated autologous pericardium. RESULTS There were no conversion to aortic valve replacement and no concomitant annulus enlargement. There were two inhospital mortalities resulting from a noncardiac cause. selleck kinase inhibitor Three patients underwent reoperation owing to aortic regurgitation (n = 2) and infective endocarditis (n = 1). One patient underwent a pacemaker implantation for complete atrioventricular block. The mean follow-up period was 28.0 ± 22.7 months. Postoperative TTE showed a mean peak pressure gradient average of 18.3 ± 9.4 mmHg and a calculated mean EOAi of 1.18 ± 0.35 cm2/m2. The freedom from reoperation rates were 94.1% and 90.8% at 1 year and 5 years of follow-up, respectively. The overall survival rates were 91.2% and 76.8% at 1 and 5 years of follow-up, respectively. CONCLUSIONS The midterm outcome of AVNeo for AS with a small annulus was excellent. The long-term outcome and reliability of this procedure must be fully clarified.
