HIGH YIELD IRRIGATED CORN: IMPLEMENTING RESEARCH AND ADAPTING FOR PROFITABLE PRODUCTION

ABSTRACT Irrigated corn producers on the High Plains are frequently confronted with issues that affect the profitability of their operations. The rapid adoption of new methods and technologies that preserve profitability is important for the economic sustainability of High Plains farmers. Traditional research is one method of identifying best management practices that may improve grower productivity and profitability. However, dissemination and implementation of research across broad geographies can be challenging. The scientific method often precludes investigation across a diverse set of variables common within and across farms. Private industry can augment implementation of scientific methods identified as profitable best management practices by employing resources necessary for wide scale spatial and temporal demonstrations. Furthermore, these investigations can be instrumental in prompt identification of processes and practices that improve producer efficiencies and/or profitability. The work and investigations summarized in this paper will demonstrate the use of spatial and temporal observations to identify best management practices for multiple nitrogen (N) applications through corn development. Also, the extension of university research on P and K starter fertilizer and its adoption and implementation by growers will be discussed

Growing Healthy Kids: A School Enrichment Nutrition Education Program to Promote Healthy Behaviors for Children

The Growing Healthy Kids Program is a school-based nutrition education program that teaches students in Kindergarten through 2nd grade about healthy eating, physical activity, and how their body uses food. Pre- and post-knowledge data is collected from the students to measure changes in nutrition knowledge. In the first 2 years of the program, significant improvements in nutrition knowledge were found in all three grades. Teachers reported that students were more aware of the importance of nutrition and were making healthier meal and/or snack choices at the end of the program

Electronic gaming machine characteristics: it's the little things that count

A range of gamblers, from low-frequency social gamblers through to problem gamblers in treatment, participated in focus groups discussing the characteristics of Electronic Gaming Machines (EGMs) that they found attractive. Analyses of the resulting transcripts resulted in two groups of EGM characteristics being identified as important, one group associated with winning and one with betting. Overall, free spin features were identified in all groups as the most attractive characteristic of EGMS. Beyond that it was smaller win-related characteristics, and low-denomination machines with multiple playable lines that were associated with increased duration and intensity of gambling behaviour. The important characteristics were consistent across different levels of gamblers, with the key behavioural difference being a self-reported ‘expertise’, and ‘strategic’ approach to gambling amongst higher-frequency gamblers and problem gamblers in treatment. The key characteristics all occur frequently and result in more wins and extended gambling sessions. The patterns identified resonated with established behavioural principles, and with models describing the development of problem gambling and addictions more generally

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

The US Program in Ground-Based Gravitational Wave Science: Contribution from the LIGO Laboratory

Recent gravitational-wave observations from the LIGO and Virgo observatories have brought a sense of great excitement to scientists and citizens the world over. Since September 2015,10 binary black hole coalescences and one binary neutron star coalescence have been observed. They have provided remarkable, revolutionary insight into the "gravitational Universe" and have greatly extended the field of multi-messenger astronomy. At present, Advanced LIGO can see binary black hole coalescences out to redshift 0.6 and binary neutron star coalescences to redshift 0.05. This probes only a very small fraction of the volume of the observable Universe. However, current technologies can be extended to construct "3rd Generation" (3G) gravitational-wave observatories that would extend our reach to the very edge of the observable Universe. The event rates over such a large volume would be in the hundreds of thousands per year (i.e. tens per hour). Such 3G detectors would have a 10-fold improvement in strain sensitivity over the current generation of instruments, yielding signal-to-noise ratios of 1000 for events like those already seen. Several concepts are being studied for which engineering studies and reliable cost estimates will be developed in the next 5 years
