Pyrolysis can realise the harmlessness, reduction and resource utilisation of petroleum sludge in a short period. In the present work, a tank bottom sludge (SSOS) and a landing sludge (SLOS) from Shengli Oilfield were used for experimental research. Thermogravimetric testing is used to initially determine the optimal range of pyrolysis temperature. Pyrolysis experiments were performed in a tube furnace reactor. Pyrolysis products were collected and analysed separately. The char yield of SSOS and SLOS were 50% and 70%, respectively. Although there are differences in the oil content of the two types of petroleum sludge, the oil yield remained nearly the same, which were both between 7% and 8%. As the pyrolysis temperature was raised to 500°C, the yield of each product did not change greatly while their composition had obvious changes. High temperature is more conducive to the production of small molecule products. Result showed that pyrolysis treatment of petroleum sludge can effectively recover energy materials in the form of pyrolysis gas and oil. The heating value of char is lower than that of petroleum sludge, which means that char is not suitable for direct use as fuel. Pyrolysis treatment also showed good curing effect on Cr, which reached 85%. However, the solidification effect decreased as pyrolysis temperature increasing. It is necessary to pay attention to the heavy metal contained in char as soil improver. The rich surface structure of char provides evidence to produce high value-added carbon materials.Bacterial Panicle Blight (BPB), caused by the bacterium Burkholderia glumae, has affected rice production worldwide. In spite of its importance, neither the disease nor its causal agent are well understood. Moreover, methods to manage BPB are still lacking. Nevertheless, the emerging importance of this pathogen has stimulated research to identify the mechanisms of pathogenicity, to gain insight into plant disease resistance, and to develop strategies to manage the disease. In this review, we consolidate current information regarding the virulence factors that have been identified in B. glumae and present a model of the disease and the pathogen. We also provide an update on the current research status to develop methods to control the disease especially through biological control approaches and through the development of resistant cultivars.The objective of this study was to evaluate the validity and reliability of NG-Test® when used as a finger-prick test on healthcare workers and to compare it to the ELISA Wantai Immunoassay. Fifty-one healthcare workers who were RT-PCR SARS-CoV-2 positive and 59 who were RT-PCR SARS-CoV-2 negative accepted to participate in this study. They were subjected to an NG-Test® finger-prick test and collection of a blood sample on the same day. A second NG-Test® on another finger was performed for the first 30 cases and controls and read blinded to the first. Sera obtained from blood samples were used to perform the Wantai SARS-CoV-2 ELISA. The interobserver agreement for the NG-Test® test was perfect (kappa coefficient = 100% [98%-100%]). The sensitivity of NG-Test® was estimated to be 85% [71.9%-92.3%] and the specificity 98.3% [95.0%-100.0%]) for both IgG and IgM. The percentage of agreement between the Wantai immunoassay and NG-Test® was 92.73% for IgG (Kappa = 0.85 [0.75-0.95]) and 65.45% (Kappa = 0.42 [0.26-0.58]) for IgM. Our study highlights the need to validate rapid immunoassay tests under real-life conditions. If NG-Test® is used in seroprevalence surveys, we recommend that its diagnostic performance be taken into consideration to obtain a reliable estimation.Suicide is a leading cause of death among college students. Although previous work indicates that the (hazardous) use of alcohol contributes to suicidal ideation/risk, little work has examined potential underlying explanatory factors. One example is anxiety sensitivity (AS). The current study evaluated whether AS explains associations between hazardous drinking and suicidal ideation and risk among college students. Data from racially/ethnically diverse students (N = 1,206; 76.7% non-White; Mage = 22.13) were analyzed. Hazardous drinking was a significant predictor of suicidal ideation (p less then 0.001) and risk (p less then 0.001). There were significant indirect associations of hazardous drinking via AS with both ideation (b = 0.07, 95% CI [0.05, 0.10]) and risk (b = 0.04, 95% CI [0.03, 0.06]); AS explained a significant portion of variance in both associations (42.6-51.4%). AS cognitive concerns (but not physical or social concerns) contributed significantly to the explanatory pathways. Students who engaged in hazardous drinking were also greater than twice as likely to screen positive for suicide risk (p less then 0.001). The findings suggest that AS, particularly cognitive concerns, partially accounts for the associations between hazardous drinking and suicidal ideation/risk. https://www.selleckchem.com/products/oxiglutatione.html Hazardous drinking may exacerbate AS which, in turn, may influence suicidal ideation and risk; however, results need to be replicated with longitudinal data. Injectable contraceptive use is common, with 74 million users worldwide. Use of the injectable contraceptive depot medroxyprogesterone acetate (DMPA) is associated with bone mineral density loss. We hypothesize that increased bone resorption with DMPA use allows for mobilization of the toxic metal lead stored in bone to blood, presenting users with increased systemic exposure to lead. The objective of our study was to investigate the association between current DMPA use and blood lead concentrations. We conducted a cross-sectional analysis using enrollment data from the Study of Environment, Lifestyle & Fibroids (SELF), a cohort of 1,693 African-American women who were 23-35 years of age. Data on DMPA use were collected by computer-assisted telephone interview. Blood lead concentrations were measured in whole blood samples among 1,548 participants (91% of cohort). We estimated the adjusted percent difference in blood lead concentrations and 95% confidence intervals (CI) between current DMPA users and nonusers using multivariable linear regression.
