1 U/L, 95% confidence interval (CI) 1.3, 22.9), simple silicosis (28.7 U/L, 95% CI 21.3, 36.0) and complicated silicosis (36.0 U/L, 95% CI 25.2, 46.9). There was a small negative association with gas transfer, but no associations with exposure duration or spirometry.

sACE levels were noted to be higher in artificial stone workers with silicosis compared to those without disease and was highest in those with complicated silicosis. Longitudinal follow up is required to evaluate sACE as a prognostic biomarker for workers with this rapidly emerging occupational lung disease.

Patients with Chronic Obstructive Pulmonary Disease with chronic respiratory failure (COPD-CRF) experience high mortality and healthcare utilization. Non-invasive home ventilation (NIVH) is increasingly used in such patients. We examined the associations between NIVH and survival, hospitalizations, and emergency room (ER) use in COPD-CRF Medicare beneficiaries.

Retrospective cohort study using the Medicare Limited Data Set (2012-2018). Patients receiving NIVH within two months of CRF diagnosis (treatment group) were matched on demographic and clinical characteristics to patients never receiving NIVH (control group). CRF diagnosis was identified using ICD-9-CM/ICD-10-CM codes. Time to death, first hospitalization, and first ER visit were estimated using Cox regressions.

After matching, 517 patients receiving NIVH and 511 controls (mean age 70.6 years, 44% male) were compared. NIVH significantly reduced risk of death (aHR 0.50; 95%CI 0.36-0.65), hospitalization (aHR 0.72; 95%CI 0.52-0.93), and ER visit (aHR 0.48; 95%CI 0.38-0.58) at diagnosis. The NIVH risk reduction became smaller over time for mortality and ER visits, but continued to accrue for hospitalizations. One-year post-diagnosis, 28% of treated patients died versus 46% controls. For hospitalizations and ER visits, 55% and 72% treated patients experienced an event, respectively, versus 67% and 92% controls. The relative risk reduction was 39% for mortality, 17% for hospitalizations, and 22% for ER visits. Number needed to treat were 5.5, 9, and 5 to prevent a death, hospitalization, or ER visit one-year post-diagnosis, respectively.

NIVH treatment is associated with reduced risk of death, hospitalizations, and ER visits among COPD-CRF Medicare beneficiaries.

NIVH treatment is associated with reduced risk of death, hospitalizations, and ER visits among COPD-CRF Medicare beneficiaries.India is one of the world's largest emerging economies and, therefore, has a critical role to play in ensuring global sustainability, while the Indian economy is also prioritizing energy security. The paper explores the dynamic linkages between energy security captured through national-level energy use, foreign direct investment (FDI), economic output, carbon emissions, and trade openness in India spanning the period from 1978 to 2016 in a multivariate framework based on the theoretical premise of an Environmental Kuznets Curve. Time series econometric modelling based on the ARDL model and VECM Granger causality tests are employed for this purpose. The results confirm the presence of a co-integrating relationship and finds a strong energy-output-CO2-FDI long-run nexus. A 1% increase in FDI results in a 0.013% reduction in energy use. Energy use is found to be Granger caused by output, carbon emissions, FDI and trade openness in the long-run. The adoption of energy-efficient techniques through FDI is essential for reducing carbon emissions in India based on our findings. The Indian government should also galvanize FDI inflow in the renewable energy sectors by assuring incentives to investors to concurrently achieve favorable macroeconomic outcomes and ensure sustainable economic development. These are globally important policy lessons for other developing and emerging economies.Switchgrass, both raw and torrefied, was tested for its ability to sorb water or oil. The cyclic performance was also examined, utilizing centrifugal extraction as the regeneration method. Both oil and water sorption capacity increase with the decreasing size of raw switchgrass particles. Results indicate that 3 mm raw switchgrass can sorb water at a capacity of about 6 times its mass and can sorb oil at a capacity of about 3 times its mass, which makes it a suitable biodegradable sorbent. Torrefaction at 220 °C for 30 min reduces water sorption capacity by an average of 55% but does not have a statistically significant impact on oil sorption. Sorption of liquid is negatively correlated to particle size. Centrifugation is able to partially desorb either liquid from the sorbent, and subsequent sorption cycles do not display lower sorption capacity than the first cycle when calculated on a dry mass basis.Three of the primary functions of green roofs in urban areas are to delay rainwater runoff, moderate building temperatures, and ameliorate the urban heat island (UHI) effect. A major impediment to the survival of plants on an unirrigated extensive green roof (EGR) is the harsh rooftop environment, including high temperatures and limited water during dry periods. Factors that influence EGR thermal and hydrologic performance include the albedo (reflectivity) of the roof and the composition of the green roof substrate (growing media). In this study we used white, reflective shading structures and three different media formulations to evaluate EGR thermal and hydrologic performance in the Pacific Northwest, USA. Shading significantly reduced daytime mean and maximum EGR media temperatures and significantly increased nighttime mean and minimum temperatures, which may provide energy benefits to buildings. Mean media moisture was greater in shaded trays than in exposed (unshaded) trays but differences were not statistically significant. find more Warmer nighttime media temperatures and lack of dew formation in shaded trays may have partially compensated for greater daytime evaporation from exposed trays. Media composition did not significantly influence media temperature or moisture. Results of this study suggest that adding shade structures to green roofs will combine thermal, hydrologic, and ecological benefits, and help achieve temperature and light regimes that allow for greater plant diversity on EGRs.
