El objetivo de esta investigación es identificar y discutir las estrategias sostenibles más ecoeficientes para aprovechar o reducir emisiones NOX, SOX polvos SiO2 en la fabricación cemento, con el mejorar competitividad industria cementera México. diseño fue cualitativo, observacional deductivo. Los resultados mostraron que los biorreactores residuos SOx tienen mayor ecoeficiencia; seguido domo...

This study aims to estimate the amount of air pollutants emitted from heavy industrial facilities in North Korea. The industry sector Korea was classified according South Korean definition, and pollutant emissions that it generated were estimated for 2017. Emissions carbon monoxide (CO), nitrogen oxides (NOx), sulfur (SOx) by 22, 73, 31%, respectively, those Korea’ emissions. Moreover, CO, NOx,...

This paper exploits a natural quasi-experiment to investigate the effects of the Sarbanes-Oxley Act (SOX) on corporate innovation: firms with a public float under $75 million can delay compliance with Section 404 of the Act. We find a significant decrease in the number of patents and patent citations for firms that are subject to Section 404 compliance relative to firms that are not. This effec...

We describe the expression pattern of Sox8, Sox9 and Sox10 during the development of the chick embryo heart. These Sox genes constitute the group E of the large Sox family of transcription factors. We show that the expression of Sox8, Sox9 and Sox10 in the developing heart correlates with heart septation and with the differentiation of the connective tissue of the valve leaflets. Sox10 appears ...

From the cocktail of four factors that were able to induce pluripotent stem cells from differentiated cells, Oct-4, c-Myc, Sox-2 and Klf4, only Oct-4 was not expressed during regeneration in newts. To explore the possible action of this stemness factor we developed an assay where we introduced exogenous Oct-4 protein to an in vitro system for lens regeneration in newts. We found that exogenous ...

ammalian sex-determining factors with homology to DNA binding proteins are required for splicing, according to a study by Paolo SassoneCorsi and coworkers at the Université Louis Pasteur (Strasbourg, France). Examination of high mobility group (HMG) domain containing SRY and Sox proteins demonstrated a surprising but clear association with splicing complexes. SRY, the testis-determining factor ...

We have cloned three sox genes in zebrafish (Danio rerio), one related to human and chicken SOX21, and two related to mammalian and chicken Sox-11. Zebrafish sox21, sox11A and sox11B transcripts are accumulated in the egg, are present in all cells until gastrulation and become restricted later to the developing central nervous system (CNS); expression in adults is undetectable. sox21 is express...

We document that the period following the passage of the Sarbanes Oxley Act of 2002 (SOX) is associated with a significant reduction in compensation-based incentives to take risk, which is related to a decline in risky investments. Moreover, consistent with the rules in SOX directly affecting CEOs’ incentives to take risk, we document that the decline in risky investments exceeds the amount tha...
