Sustainability, Vol. 7, Pages 384-397: Maize Production Responsiveness to Land Use Change and Climate Trends in Cameroon

31.12.2014 | Epule, Terence Epule; Bryant, Christopher Robin, Sustainability, 2014

Most studies on the responsiveness of maize production to various variables have dwelled on the responsiveness of maize production to variations in precipitation or temperature. This study seeks to verify the response of maize production in Cameroon to both climate trends and land use change. ...


Comparison of reduced and sulfided CoMo/γ‐Al2O3 catalyst on hydroprocessing of pretreated bio‐oil in a continuous packed‐bed reactor

29.12.2014 | Divya R. Parapati, Vamshi K. Guda, Venkata K. Penmetsa, Sathish K. Tanneru, Brian Mitchell, Philip H. Steele, Environmental Progress, 2014

Pretreated bio‐oil was hydroprocessed with conventional sulfided CoMo/γ‐Al2O3 catalyst in a continuous packed‐bed reactor. Hydroprocessing experiments were performed at a temperature of 350 to 400°C, 1500 psig hydrogen pressure, using a hydrogen flow rate of 500 mL/min at a liquid hourly space ...


IJERPH, Vol. 12, Pages 354-370: Identifying Environmental Risk Factors of Cholera in a Coastal Area with Geospatial Technologies

29.12.2014 | Xu, Min ; Cao, Chunxiang ; Wang, Duochun ; Kan, Biao, International Journal of Environmental Research and Public Health, 2014

Satellites contribute significantly to environmental quality and public health. Environmental factors are important indicators for the prediction of disease outbreaks. This study reveals the environmental factors associated with cholera in Zhejiang, a coastal province of China, using both Remote ...


Development and field testing of a miniaturized sampling system for simultaneous sampling of vapours and droplets

24.12.2014 | Dietmar Breuer; George C. Dragan; Claudia Friedrich; Carsten Möhlmann; Ralf Zimmermann, Journal of Environmental Monitoring, 2014

The sampling of semi volatiles (SV) in workplaces may lead to different results as measurements may be affected by sampling bias. The new European Standard EN 13936 defines “semi-volatiles” as substances with vapour pressures in the range between 0.001 and 100 Pa at room temperature. EN 13936 ...


IJERPH, Vol. 12, Pages 1-15: A Systematic Review and Meta-Analysis of Dengue Risk with Temperature Change

23.12.2014 | Fan, Jingchun ; Wei, Wanxia ; Bai, Zhenggang ; Fan, Chunling ; Li, Shulan ; Liu, Qiyong ; Yang, Kehu, International Journal of Environmental Research and Public Health, 2014

Dengue fever (DF) is the most serious mosquito-borne viral disease in the world and is significantly affected by temperature. Although associations between DF and temperatures have been reported repeatedly, conclusions have been inconsistent. Six databases were searched up to 23 March 2014, ...


IJERPH, Vol. 12, Pages 227-253: The Excess Heat Factor: A Metric for Heatwave Intensity and Its Use in Classifying Heatwave Severity

23.12.2014 | Nairn, John R.; Fawcett, Robert J. B., International Journal of Environmental Research and Public Health, 2014

Heatwaves represent a significant natural hazard in Australia, arguably more hazardous to human life than bushfires, tropical cyclones and floods. In the 2008/2009 summer, for example, many more lives were lost to heatwaves than to that summer’s bushfires which were among the worst in the history ...


Evaporation Kinetics of Laboratory-Generated Secondary Organic Aerosols at Elevated Relative Humidity

23.12.2014 | Jacqueline Wilson; Dan Imre; Josef Beránek; Manish Shrivastava; Alla Zelenyuk, Environmental Science & Technology, 2014

Secondary organic aerosols (SOA) dominate atmospheric organic aerosols that affect climate, air quality, and health. Recent studies indicate that, contrary to previously held assumptions, at low relative humidity (RH) these particles are semisolid and evaporate orders of magnitude slower than ...


IJERPH, Vol. 12, Pages 254-267: Developing a Heatwave Early Warning System for Sweden: Evaluating Sensitivity of Different Epidemiological Modelling Approaches to Forecast Temperatures

23.12.2014 | Åström, Christofer ; Ebi, Kristie L.; Langner, Joakim ; Forsberg, Bertil, International Journal of Environmental Research and Public Health, 2014

Over the last two decades a number of heatwaves have brought the need for heatwave early warning systems (HEWS) to the attention of many European governments. The HEWS in Europe are operating under the assumption that there is a high correlation between observed and forecasted temperatures. We ...


New Insights into the N2O Formation Mechanism over Pt-BaO/Al2O3 Model Catalysts Using H2 As a Reductant

22.12.2014 | Jinxin Zhu; Jun Wang; Jianqiang Wang; Liangfang Lv; Xiuting Wang; Meiqing Shen, Environmental Science & Technology, 2014

The N2O formation mechanism was investigated over a Pt-BaO/Al2O3 catalyst applied on light-duty diesel vehicles using H2 as a reductant in the absence and presence of H2O. In the absence of H2O, N2O forms mainly at the initial phase of lean NOx trapping; while in the presence of H2O, N2O appears ...


Nanoparticle-Supported Lipid Bilayers as an In Situ Remediation Strategy for Hydrophobic Organic Contaminants in Soils

18.12.2014 | Hairong Wang; Bojeong Kim; Stephanie L. Wunder, Environmental Science & Technology, 2014

Polycyclic aromatic hydrocarbons (PAHs) are persistent environmental organic contaminants due to their low water solubility and strong sorption onto organic/mineral surfaces. Here, nanoparticle-supported lipid bilayers (NP-SLBs) made of 100-nm SiO2 nanoparticles and the zwitterionic lipid ...
