Comprehensive assessment of urban water resources carrying capacity based on basin unit: a case study of Qingdao, China

With the quick development of social economy, the sharp contradiction between supply and demand of urban water resources is becoming much more obvious. Comprehensive assessment of urban water resources carrying capacity is of great significance to urban sustainable development planning. In this study, the urban water resources carrying capacity of Qingdao based on basin unit over 2010–2030 is predicted using analytic hierarchy process and system dynamics method. The results showed that the total water demand of all the 9 basins have an upward annual trend from 2017 to 2030, among which the domestic water consumption increase obviously. The urban water resource carrying capacity indexes in all basin over 2017–2030 show a downward annual trend under the current social development model. So it is urgent to improve the water resource carrying capacity of each river basin by means of industrial structure optimization and upgrading and active development of new water sources.

Regional SST and SLP conditions related to tornado 'outbreak' environments 15 days later

Global climate features are known to influence tornado frequency in the U.S., but more work needs to focus on understanding the extent to which climate variables contribute to increases in CAPE and shear on days with an outbreak of at least ten tornadoes. Here the authors quantify the conditional relationships between precursor SST and SLP variables and localized extremes of CAPE and shear associated with large outbreaks. They do this by fitting linear regressions to global climate variables averaged over the fifteen days before the outbreak to estimate the changes in CAPE and shear on days with at least ten tornadoes. Results show that for every 1° increase in the SST gradient between the Gulf of Alaska and the Caribbean, DLBS increases by 0.88 m s¯¹, SLBS increases by 0.62 m s¯¹, and CAPE decreases by 50.6 J kg¯¹, conditional on at least ten tornadoes, and holding the other variables constant. Further, results show that for every 1° E increase in longitude, DLBS increases by 0.15 m s¯¹, SLBS increases by 0.38 m s¯¹, and CAPE decreases by 39.3 J kg¯¹, conditional on at least ten tornadoes, and holding the other variables constant. Additionally, SLBS is the only environmental factor that has a significant upward annual trend.

Analysis on Data Mining Tools Used in Business Intelligence and Inventions

This paper will evaluate data mining tools for competitive intelligence and technology. Data analyzers i.e. Thomson and OmniViz are the tools for completing diversified and sophisticated mathematical analyses of data. AnaVist and Aureka are considerable for modest visualization of statistics and itoplistsi is used for creating maps that are stylish. Novel features of OmniViz during the comparison of other tested tools are used for visualizing clustered data from difference viewpoints, which makes it possible to assess the attributes using patent map animation. The Thomson data analyzer provides effective tools that compare various subsets for data, such as the identification of unique attribute values. In citation assessments, Aureka is used as well as in illustrative patent maps. AnaVist is the best in retrieving basis statistics smoothly and quickly. The findings from four tools were similar, despite the fact that various databases for data retrieving were utilized. Superior investors and assignees list were the same, since they were an annual trend for geographical and technological business segments. Nonetheless, the conclusions from the findings were that business decisions are made using their tools to enhance competitive intelligence.

Annual trend of neonatal mortality and its underlying causes: population-based study – São Paulo State, Brazil, 2004–2013

Background Population-based studies analyzing neonatal deaths in middle-income countries may contribute to design interventions to achieve the Sustainable Development Goals, established by United Nations. This study goal is to analyze the annual trend of neonatal mortality in São Paulo State, Brazil, over a 10-year period and its underlying causes and to identify maternal and neonatal characteristics at birth associated with neonatal mortality. Method A population-based study of births and deaths from 0 to 27 days between 2004 and 2013 in São Paulo State, Brazil, was performed. The annual trend of neonatal mortality rate according to gestational age was analyzed by Poisson or by Negative Binomial Regression models. Basic causes of neonatal death were classified according to ICD-10. Association of maternal demographic variables (block 1), prenatal and delivery care variables (block 2), and neonatal characteristics at birth (block 3) with neonatal mortality was evaluated by Poisson regression analysis adjusted by year of birth. Results Among 6,056,883 live births in São Paulo State during the study period, 48,309 died from 0 to 27 days (neonatal mortality rate: 8.0/1,000 live births). For the whole group and for infants with gestational age 22–27, 28–31, 32–36, 37–41 and ≥ 42 weeks, reduction of neonatal mortality rate was, respectively, 18 %, 15 %, 38 %, 53 %, 31 %, and 58 %. Median time until 50 % of deaths occurred was 3 days. Main basic causes of death were respiratory disorders (25 %), malformations (20 %), infections (17 %), and perinatal asphyxia (7 %). Variables independently associated with neonatal deaths were maternal schooling, prenatal care, parity, newborn sex, 1st minute Apgar, and malformations. Cesarean delivery, compared to vaginal, was protective against neonatal mortality for infants at 22–31 weeks, but it was a risk factor for those with 32–41 weeks. Conclusions Despite the significant decrease in neonatal mortality rate over the 10-year period in São Paulo State, improved access to qualified health care is needed in order to avoid preventable neonatal deaths and increase survival of infants that need more complex levels of assistance.

Abstract 13820: Temporal Trends and Prognosis of Physical Exam Findings in Patients Hospitalized With Acute Decompensated Heart Failure With Preserved versus Reduced Ejection Fraction the Aric Study Community Surveillance

Introduction: Bedside evaluation of congestion remains important in both heart failure (HF) with reduced and preserved ejection fraction (HFrEF and HFpEF). Whether presence of physical exam findings have changed over time, or if prognosis of physical examination differs by HF type is uncertain. Methods: From 2005-2014, the Atherosclerosis Risk in Communities (ARIC) Study conducted hospital surveillance of acute decompensated heart failure (ADHF). Events were verified by physician review, and clinical data were abstracted from the medical record. We examined presence of 3 physical exam findings suggesting congestion: lower extremity edema, jugular venous distension, and pulmonary rales > 1/3 of the lung field. Analyses were weighted by sampling fractions. Results: Of 24,937 hospitalizations for ADHF (mean age 75 years, 53% women, 32% black), 47% were HFpEF. Presence of edema increased from 2005-2009 to 2010-2014, both for HFpEF (66% to 72%; P for annual trend = 0.002) and HFrEF (62% to 67%; P for annual trend = 0.009), while presence of rales and jugular distention remained stable. There were 2640 (11%) and 7766 (31%) deaths within 28 days and 1 year of hospitalization, respectively. Patients with HFpEF and all 3 physical exam signs had a greater risk of short- and long-term mortality ( Figure ). After adjustments for demographics and length of stay, there was a differential association between clinical signs and 28-day mortality by HF type ( P for interaction = 0.02). Presence of all 3 vs. <3 signs was associated with increased mortality for HFpEF (HR = 2.22; 95% CI: 1.51 - 3.27) but not HFrEF (HR = 1.13; 95% CI: 0.79 - 1.61). A similar association was observed for 1-year mortality (HFpEF: HR = 1.49; 95% CI: 1.13 - 1.98) vs. (HFrEF: HR = 1.13; 95% CI: 0.91 - 1.40). Conclusion: The presence of edema on physical examination of patients with ADHF has increased in recent years, both for HFpEF and HFrEF. However, the prognostic utility of physical exam signs of congestion may differ by HF type.

Abstract 130: Mechanical, Team-focused, Video-Reviewed Cardiopulmonary Resuscitation Improves Trends in Survival to Discharge and Cardiac Arrest Performance Measures

Background: Our previous research demonstrated an improvement in ROSC after implementing a bundle including mechanical, team-focused, video-reviewed cardiopulmonary resuscitation (MTV-CPR) for cardiac arrest patients in our ED. The aims of this study are to assess trends in cardiac arrest outcomes and improvements in cardiac arrest performance measures after the implementation of our MTV-CPR intervention. Methods: In 2018, our ED began using mechanical CPR; a new team-focused strategy with nurse led ACLS; and biweekly video-review of cardiac arrests. The primary outcome of this study was to evaluate the annual trend in survival to discharge from 2017 (the year before implementing MTV-CPR) through 2019. Secondary outcomes included ROSC and survival to admission. The Cochrane-Armitage test was used to evaluate annual trends in outcomes over the 3-year study period. We also sought to determine if an improvement in cardiac arrest performance measures occurred over the two years of our MTV-CPR intervention using Wilcoxon rank sum and two-sample t-tests. Cardiac arrest performance measures are listed in the table. Results: The groups were similar at baseline over the 3-year study period. 291 patients were included in the study (96 in 2017, 96 in 2018, and 99 in 2019). Survival to discharge improved from 3.1% in 2017 to 5.2% in 2018 to 10.1% in 2019 (p= 0.043); ROSC improved from 26% to 41.7% to 40.4% (p=0.038); survival to admission went from 19.8% to 25% to 29.3% but was not significantly different (p=0.124). Results for cardiac arrest performance measures are reported in the table. There were significant reductions in time to bed transfer, rhythm determination, mechanical CPR placement, and duration of each chest compression interruption due to ultrasound. Conclusions: Implementation of our MTV-CPR intervention for cardiac arrest patients resulted in improved trends in survival to discharge and ROSC, as well as improvements in multiple cardiac arrest performance measures.

Climatology of the relative humidity in the Carpathian Valley

&lt;p&gt;The reports about the climate change mostly focus about the trend of the temperature or precipitation. However, the relative humidity is also an important characteristic of the atmosphere, e.g. it impacts both the cloud and fog formation. The trends of the relative humidity in the changing climate have been found to be rather uncertain. &amp;#160;In this research the climatological trend of the relative humidity in the Carpathian Valley was studied. Analysis of the long-term observed database from eight meteorological stations was used to present the annual and seasonal trends of the relative humidity. The annual trend was found to be between 2-3% in every meteorological station. The results show that the relative humidity has decreased every season but in autumn, when the trend of it has not been consistent. While the most significant decrease has been occurred during spring, the decrease was negligible during autumn.&lt;/p&gt;
