Dissemination of Evidence by Cochrane Public Health Europe in German-Speaking Countries: An Online Stakeholder Survey

Objectives: To investigate the reach and impact of “Infomails”, email summaries of Cochrane reviews in German, regularly disseminated by Cochrane Public Health Europe (CPHE) to stakeholders in Austria, Germany and Switzerland. Methods: We analysed email campaign reports from 15 Infomails delivered until November 2020. Furthermore, we invited all previous Infomail recipients to participate in an online survey on the impact and perceptions regarding our Infomails in November 2020. We analysed the results using descriptive statistics. Results: The Infomails’ open rate ranged from 10.9% to 39.3% (median 26.0%), and the median click rate on the embedded links was 28.0% (range 8.6–53.8%), highest for nutrition and prevention topics. Out of 1259 recipients, 267 (21.2%) completed our survey. Infomails were most used in discussions, writing reports or statements, for policy or strategy development or programme or guideline development. Persons who remembered receiving Infomails rated them as useful, comprehensible or informative. Conclusion: Infomails summarising recent Cochrane reviews were considered useful for the daily work of public health stakeholders in German-speaking countries. Regular targeted messaging may increase the perceived usefulness

Scientific and Technical Assistance for the Deployment of a Flexible Airborne Spectrometer System During C-MAPExp and COMEX

The COMEX (CO2 and MEthane eXperiment) campaign supports the mission definition of CarbonSat and HyspIRI (Hyperspectral Infrared Imager) by providing representative airborne remote sensing data MAMAP (Methane Airborne MAPper) for CarbonSat; the Airborne Visual InfraRed Imaging Spectrometer (Classic & Next Generation) AVIRISC/AVIRISNG for HyspIRI as well as ground-based and airborne insitu data. The objectives of the COMEX campaign activities are (see Campaign Implementation Plan (RD4)): 1. Investigate spatial/spectral resolution tradeoffs for CH4 anomaly detection and flux inversion by comparison of MAMAPderived emission estimates with AVIRIS/AVIRISNG derived data. 2. Evaluate sunglint observation geometry on CH4 retrievals for marine sources. 3. Characterize the effect of Surface Spectral Reflectance (SSR) heterogeneity on trace gas retrievals of CO2 and CH4 for medium and lowresolution spectrometry. 4. Identify benefits from joint SWIR/TIR (ShortWave InfraRed/Thermal InfraRed ) data for trace gas detection and retrieval by comparison of MAMAP and AVIRIS/AVIRISNG NIR/SWIR data with MAKO (Aerospace Corp.)TIR data. The ability to derive emission source strength for a range of strong emitting targets by remote sensing will be evaluated from combined AVIRISNG and MAMAP data, adding significant value to the HyspIRI campaign AVIRISNG dataset. The data will be used to quantify anomalies in atmospheric CO2 and CH4 from strong local greenhouse gas sources e.g. localized industrial complexes, landfills, etc. and to derive CO2 and CH4 emissions estimates from atmospheric gradient measurements. The original campaign concept was developed by University of Bremen and BRI. The COMEX campaign is funded bilaterally by NASA and ESA (European Space Agency). Whereas NASA funds the US part of the project via a contract with Dr. Ira Leifer, BRI (Bubbleology Research International), the contribution of MAMAP to the COMEX campaign is funded by ESA within the COMEXE project and NASA with respect to a 50 percent contribution to the flight-related costs of flying MAMAP on a US aircraft. The Data Acquisition Report (RD9) describes the instrumentation used, the measurements made by the team during the COMEX campaign in May/June 2014 and August/September 2014 in California, and an initial assessment of the data quality

Biochar reduces the efficiency of nitrification inhibitor 3,4-dimethylpyrazole phosphate (DMPP) mitigating N2O emissions

Among strategies suggested to decrease agricultural soil N2O losses, the use of nitrification inhibitors such as DMPP (3,4-dimethylpyrazole phosphate) has been proposed. However, the efficiency of DMPP might be affected by soil amendments, such as biochar, which has been shown to reduce N2O emissions. This study evaluated the synergic effect of a woody biochar applied with DMPP on soil N2O emissions. A incubation study was conducted with a silt loam soil and a biochar obtained from Pinus taeda at 500 degrees C. Two biochar rates (0 and 2% (w/w)) and three different nitrogen treatments (unfertilized, fertilized and fertilized + DMPP) were assayed under two contrasting soil water content levels (40% and 80% of water filled pore space (WFPS)) over a 163 day incubation period. Results showed that DMPP reduced N2O emissions by reducing ammonia-oxidizing bacteria (AOB) populations and promoting the last step of denitrification (measured by the ratio nosZI + nosZII/nirS + nirK genes). Biochar mitigated N2O emissions only at 40% WFPS due to a reduction in AOB population. However, when DMPP was applied to the biochar amended soil, a counteracting effect was observed, since the N2O mitigation induced by DMPP was lower than in control soil, demonstrating that this biochar diminishes the efficiency of the DMPP both at low and high soil water contents.This work was funded by the Spanish Government (AGL2015-64582-C3-2-R MINECO/FEDER), by the Basque Government (IT-932-16) and by the European Union (FACCE-CSA no 276610/MIT04-DESIGN-UPVASC, FACCE-CSA no 2814ERA01A and 2814ERA02A).

The Virgin River Basin Study: A Regional Approach to Multiobjective Planning for Water and Related Resources

A joint research effort by the Utah Water Research Laboratory and the Nevado Center for Water Resources Research applied two multiobjective planning models to the Virgin River Basin in order to test the efficiency and practicality of applying such tools in water resrouces planning. The surrogate Worth Trade-off (SWT) method couples mathematical optimization to quantify trade offs among noncommensurable objectives with interviews to compare public preferences with respect to these trade offs. PROPDEMM uses information on interest group objectives, balues, willingness to pay, influence, lebel of information, etc. to compare the political feasibility of alternative courses of action. Both models were applied to assess the difficulties in doing so and the usefulness of the results. The trade offs identified by the SWT method showed agricultural water use to be so dominant in the basin that slight adjustments in irrigation efficiency could supply all foreseeable needs for additional water for other uses, such trade offs to be too inconsequential to identify and compare public preferences, and other trade offs to be impossible because of the position taken by ecologists that any environmental change would destroy a rare species of minnow. Prior to analyzing a situation by the SWT method, the planner should make sure that the trade offs will be of a magnitude meaningful to the public and that the model selected will be sufficiently refined in analyzing small units in time and space to identify locally significant trade offs. PROPDEMM showed the politically most controversial trade off to be between construction of energy generating facilities and life support for the minnow, a controbersy that would probably be decided in favor of the environmentalist because of their power and non-openness to change. Improvements to the model to do a better job of interfacing environmental with social data were recommended. Social modeling in such low population areas was found to be restricted by laws against disclosure of private information because of the very small numbers of individuals living in many evaluation units

Expansion of Agriculture in Northern Cold-Climate Regions: A Cross-Sectoral Perspective on Opportunities and Challenges

Agriculture in the boreal and Arctic regions is perceived as marginal, low intensity and inadequate to satisfy the needs of local communities, but another perspective is that northern agriculture has untapped potential to increase the local supply of food and even contribute to the global food system. Policies across northern jurisdictions target the expansion and intensification of agriculture, contextualized for the diverse social settings and market foci in the north. However, the rapid pace of climate change means that traditional methods of adapting cropping systems and developing infrastructure and regulations for this region cannot keep up with climate change impacts. Moreover, the anticipated conversion of northern cold-climate natural lands to agriculture risks a loss of up to 76% of the carbon stored in vegetation and soils, leading to further environmental impacts. The sustainable development of northern agriculture requires local solutions supported by locally relevant policies. There is an obvious need for the rapid development of a transdisciplinary, cross-jurisdictional, long-term knowledge development, and dissemination program to best serve food needs and an agricultural economy in the boreal and Arctic regions while minimizing the risks to global climate, northern ecosystems and communities

Biochar as a tool to reduce the agricultural greenhouse-gas burden – knowns, unknowns and future research needs

Agriculture and land use change has significantly increased atmospheric emissions of the non-CO2 green-house gases (GHG) nitrous oxide (N2O) and methane (CH4). Since human nutritional and bioenergy needs continue to increase, at a shrinking global land area for production, novel land management strategies are required that reduce the GHG footprint per unit of yield. Here we review the potential of biochar to reduce N2O and CH4 emissions from agricultural practices including potential mechanisms behind observed effects. Furthermore, we investigate alternative uses of biochar in agricultural land management that may significantly reduce the GHG-emissions-per-unit-of-product footprint, such as (i) pyrolysis of manures as hygienic alternative to direct soil application, (ii) using biochar as fertilizer carrier matrix for underfoot fertilization, biochar use (iii) as composting additive or (iv) as feed additive in animal husbandry or for manure treatment. We conclude that the largest future research needs lay in conducting life-cycle GHG assessments when using biochar as an on-farm management tool for nutrient-rich biomass waste streams

Chitosan Modification of Adenovirus to Modify Transfection Efficiency in Bovine Corneal Epithelial Cells

BACKGROUND: The purpose of this study is to modulate the transfection efficiency of adenovirus (Ad) on the cornea by the covalent attachment of chitosan on adenoviral capsids via a thioether linkage between chitosan modified with 2-iminothiolane and Ad cross-linked with N-[gamma-maleimidobutyryloxy]succinimide ester (GMBS). METHODOLOGY/PRINCIPAL FINDINGS: Modified Ad was obtained by reaction with the heterobifunctional crosslinking reagent, GMBS, producing maleimide-modified Ad (Ad-GMBS). Then, the chitosan-SH was conjugated to Ad-GMBS via a thioether bond at different ratios of Ad to GMBS to chitosan-SH. The sizes and zeta potentials of unmodified Ad and chitosan-modified Ads were measured, and the morphologies of the virus particles were observed under transmission electron microscope. Primary cultures of bovine corneal epithelial cells were transfected with Ads and chitosan-modified Ads in the absence or presence of anti-adenovirus antibodies. Chitosan modification did not significantly change the particle size of Ad, but the surface charge of Ad increased significantly from -24.3 mV to nearly neutral. Furthermore, primary cultures of bovine corneal epithelial cells were transfected with Ad or chitosan-modified Ad in the absence or presence of anti-Ad antibodies. The transfection efficiency was attenuated gradually with increasing amounts of GMBS. However, incorporation of chitosan partly restored transfection activity and rendered the modified antibody resistant to antibody neutralization. CONCLUSIONS/SIGNIFICANCE: Chitosan can provide a platform for chemical modification of Ad, which offers potential for further in vivo applications
