Feasibility of an onboard wake vortex avoidance system

It was determined that an onboard vortex wake detection system using existing, proven instrumentation is technically feasible. This system might be incorporated into existing onboard systems such as a wind shear detection system, and might provide the pilot with the location of a vortex wake, as well as an evasive maneuver so that the landing separations may be reduced. It is suggested that this system might be introduced into our nation's commuter aircraft fleet and major air carrier fleet and permit a reduction of current landing separation standards, thereby reducing takeoff and departure delays

Vortex interactions and decay in aircraft wakes

The dynamic interaction of aircraft wake vortices was investigated using both inviscid and viscous models. For the viscous model, a computer code was developed using a second-order closure model of turbulent transport. The phenomenon of vortex merging which results in the rapid aging of a vortex wake was examined in detail. It was shown that the redistribution of vorticity during merging results from both convective and diffusive mechanisms

Just transition: Employment projections for the 2.0 °c and 1.5 °c scenarios

© The Author(s) 2019. This section provides the input data for two different employment development calculation methods: The quantitative analysis, which looks into the overall number of jobs in renewable and fossil fuel industries and the occupational analysis which looks into specific job categories required for the solar and wind sector as well as the oil, gas, and coal industry. Results are given with various figures and tables

Making Dioramas of Women Scientists Help Elementary Students Recognize Their Contributions

The STEM movement encourages girls to consider careers in science; however, for success, common misconceptions and biases need to be dispelled, while females’ spatial thinking skills are developed. All students, both girls and boys, need exposure to the accomplishments of women scientists to appreciate their contributions and to envision females as successful scientists. This one-week study conducted during a summer day camp examined upper elementary student (n = 15; 7 females, 8 males) attitudes toward science, women in science, and the possibility of a science career before and after participation in learning about diverse accomplished women scientists and making a diorama showcasing the professional work and caring actions of one of the scientists. The efficacy of this project for upper elementary students, conducted during a summer day camp, is supported by pretest-posttest data and attitude surveys. The five-day class showed positive changes in student plans for a career in science and improved attitudes toward the importance of females becoming scientists. Directions for constructing dioramas, examples of student-made work, and creative scenes made with given craft items are provided
