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 find more 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 500C 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 valueadded carbon materialsBacterial 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 cultivarsThe objective of this study was to evaluate the validity and reliability of NGTest when used as a fingerprick test on healthcare workers and to compare it to the ELISA Wantai Immunoassay Fiftyone healthcare workers who were RTPCR SARSCoV2 positive and 59 who were RTPCR SARSCoV2 negative accepted to participate in this study They were subjected to an NGTest fingerprick test and collection of a blood sample on the same day A second NGTest 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 SARSCoV2 ELISA The interobserver agreement for the NGTest test was perfect kappa coefficient 100 98100 The sensitivity of NGTest was estimated to be 85 719923 and the specificity 983 9501000 for both IgG and IgM The percentage of agreement between the Wantai immunoassay and NGTest was 9273 for IgG Kappa 085 075095 and 6545 Kappa 042 026058 for IgM Our study highlights the need to validate rapid immunoassay tests under reallife conditions If NGTest is used in seroprevalence surveys we recommend that its diagnostic performance be taken into consideration to obtain a reliable estimationSuicide is a leading cause of death among college students Although previous work indicates that the hazardous use of alcohol contributes to suicidal ideationrisk 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 raciallyethnically diverse students N 1206 767 nonWhite Mage 2213 were analyzed Hazardous drinking was a significant predictor of suicidal ideation p less then 0001 and risk p less then 0001 There were significant indirect associations of hazardous drinking via AS with both ideation b 007 95 CI 005 010 and risk b 004 95 CI 003 006 AS explained a significant portion of variance in both associations 426514 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 0001 The findings suggest that AS particularly cognitive concerns partially accounts for the associations between hazardous drinking and suicidal ideationrisk 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 crosssectional analysis using enrollment data from the Study of Environment Lifestyle Fibroids SELF a cohort of 1693 AfricanAmerican women who were 2335 years of age Data on DMPA use were collected by computerassisted telephone interview Blood lead concentrations were measured in whole blood samples among 1548 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
