Space weather research is the principal activity at the Space Science Center, Lapan to learn characteristics and generator source of the space weather so that can mitigate its the impact on the Earth's environment as mandated in Law No. 21 Year 2013. One of them is the phenomenon of geomagnetic storms. Geomagnetic storms caused by the entry of solar wind together with the IMF Bz that leads to the south. The behavior of the solar wind parameters together with the IMF Bz before geomagnetic storms can determine the formation of geomagnetic storms that caused it. In spite that, by the solar wind parameters and IMF Bz behavior before geomagnetic storm can be estimated its intensity through the equation Dst * = 1.599 * Ptotal - 34.48. The result of this equation is obtained that the Dst minimum deviation between the raw data and the output of this equation to the geomagnetic storm events on March 17, 2013 is about of -2.51 nT or 1.9% and on the geomagnetic storm events on February 19, 2014 is about of 2.77 nT or 2, 5%. Thus, the equation Dst * = 1.599 * Ptotal - 34.48 is very good for the estimation of geomagnetic storms.

The THz Atmospheric Limb Sounder (TALIS) is a Chinese sub-millimeter limb sounder being designed by National Space Science Center of the Chinese Academy of Sciences to measure the temperature and chemical constituents vertically in the middle and upper atmosphere, with good precision and vertical resolution. This paper presents a simulation study that assesses the measurement errors and their impacts on the retrievals. Three error sources, including instrument uncertainties, calibration errors and a priori errors, are considered. The sideband weight uncertainty, the local oscillator, the pointing angle offsets and the measurement noise (NEDT), are considered as instrument uncertainties. Calibration errors consist of the hot target offset, the nonlinearity residual of the two-point calibration, use of the Rayleigh–Jeans (R–J) approximation and the choice of the antenna pattern. A priori profile errors of temperature, pressure and species are also considered. The results suggest that the antenna pattern mainly affects the retrievals in the troposphere. The NEDT is a major error source affecting all of the retrievals. The R–J approximation has a great impact upon the retrievals at 643 GHz, and should not be used. The local oscillator offset leads to an obvious error above 50 km. The effect of nonlinearity residuals cannot be neglected above 70 km. The impact of the sideband weight uncertainty and the hot target offset are relatively small. The pointing and the a priori errors can be neglected in most observation regions.

OBJECTIVES/SPECIFIC AIMS: We aim to leverage our analysis of the scientific collaboration network at a research university to design an innovative pilot program and foster scientific productivity. We test the impact of creating a new collaboration in a research community, which decreases the average network distance and accelerates the diffusion of information and expertise among the community’s investigators. METHODS/STUDY POPULATION: We mapped the whole network of co-authorship on publications and co-participation on extramurally awarded grants at the University of Florida (UF) between 2013 and 2015. We used network science methods to identify research communities of investigators who have consistently worked together and/or have other collaborators in common with at least one researcher based in the UF Health Science Center. We selected pairs of communities with (i) similar productivity levels, research interests, and network structures and (ii) no research projects in common. Communities in each pair were randomly assigned to a treatment or control group. In each treatment community, we selected 1 pair of investigators who had not collaborated in the past 3 years and whose connection would maximally reduce average network distance in the community. The pair was provided with an economic incentive to collaborate for the submission of a CTSA pilot proposal. RESULTS/ANTICIPATED RESULTS: We successfully identified 15 pairs of treatment/control communities. In each of 8 treatment communities, a pair of potential collaborators agreed to participate in the intervention. DISCUSSION/SIGNIFICANCE OF IMPACT: Network-informed Clinical Translational Science Awards (CTSA) pilot programs can identify research communities and create innovative collaborations. Statistical experiments can establish the programs’ causal effects on scientific productivity.

Abstract I describe lessons learned and the people and principles that influenced six decades of professional endeavours from graduate schools to ascending, often unexpectedly, the science and management ladder in National Oceanic and Atmospheric Administration (NOAA) fisheries, which manages US living marine resources. For this woman chemist from India, the twists of fate and love of adventure presented amazing opportunities as well as challenges. My research on cetacean biosonar as well as on the impact of fossil fuel pollution on seafood safety and the health of marine organisms taught me the value of multidisciplinary approaches and unusual alliances. Transitioning into management, and eventually as the director of Northwest Fisheries Science Center, I learned the value of transparency and empathy while communicating our results to impacted communities, and the resolve to support the science regardless of the consequences. My advice to young professionals is that the journey should be as fulfilling as reaching the goalpost. At the twilight of my own journey, I networked with NOAA Fisheries and India’s marine science community to encourage scientist exchanges and training. My participation in University of Washington’s nature and human health programme confirms my conviction that conserving healthy ecosystems is a powerful and practical approach for people and our planet.

The Impact

Augmented reality (AR) applications have recently emerged for entertainment and educational purposes and have been proposed to have positive effects on social interaction. In this study, we investigated the impact of a mobile, indoor AR feature on sociability, entertainment, and learning. We conducted a field experiment using a quiz game in a Finnish science center exhibition. We divided participants (N = 372) into an experimental group (AR app users) and two control groups (non-AR app users; pen-and-paper participants), including 28 AR users of follow-up interviews. We used Kruskal–Wallis rank test to compare the experimental groups and the content analysis method to explore AR users’ experiences. Although interviewed AR participants recognized the entertainment value and learning opportunities for AR, we did not detect an increase in perceived sociability, social behavior, positive affect, or learning performance when comparing the experimental groups. Instead, AR interviewees experienced a strong conflict between the two different realities. Despite the engaging novelty value of new technology, performance and other improvements do not automatically emerge. We also discuss potential conditional factors. Future research and development of AR and related technologies should note the possible negative effects of dividing attention to both realities.

<p>Chesapeake County Groundwater Problem</p><p>Kenneth C. Newsome Freedom High School Prince William County Virginia</p><p>Teaching students the impact of groundwater pollution and its effect on humans</p><p>This activity was modified from an activity from the Math Science Center in Richmond, Virginia.  Students construct models using six paper models of a hypothetical situation where a farmer and lighthouse keeper are having well water issues. The students are acting as a hydrogeologist and are consulting the farmer and lighthouse keeper.  This scenario is being played out on the banks of the Chesapeake Bay in Virginia.  The farmer is having trouble with his house well running dry, while his well at his barn is always supplying water.  The lighthouse keeper and his wife are wondering why their water is undrinkable, and their house plants are dying.  The lighthouse keeper claims the farmer is responsible for the undrinkable water.  The outcome is the farmer's house well is dug too shallow, while his barn well is also close to a manure pile and livestock yard.  The lighthouse keeper's well is too close to the saltwater of the Chesapeake Bay, and the intrusion of salt is making the water undrinkable.  This activity has students problem-solving water pollution issues, and this activity has them figure out the root cause of water pollution.  Students are then asked to apply this knowledge to a newly discovered planet with the same water pollution issues.       </p>

<p>For sustainable future I plan various activities, workshops, local IIT visit, Planetarium and Science center visits, arrange film screening, simulation exercises, Virtual trips, quizzes on various topics and map work, independent research for better understanding, conducting observations and finding out answers/reasons for their findings. The very purpose is to broaden their horizons and make them global citizens. According to me a class can be how the teacher wants it. If you have compassion and if you are passionate about your work then most of the work is done. While teaching Science, I always try to correlate things with day-to-day life and make students reaffirm their accumulated knowledge through nature’s very own perspective.</p><p> </p><p>One of my favorite topics is Water in our ecosystem. Today, as we all are aware of, sea levels are rising across the world due to global warming and glacial melting as a result thereof. Yet another catastrophic form of the wrath expressed by nature is in form of Flash Floods. It is a rapid flooding and an almost sudden surge in water levels within a few hours or, at times, minutes of the rainfall that causes a catastrophic loss of life and material wealth. Instances of these flash floods are increasing in number and intensity, not only in India but every elsewhere of the world. The question here is, that was it inevitable or could we have done something to prevent these. However, since the times can’t be averted, there is no use of crying over the milk that we have spilt ourselves. The spotlight today should be on ways of preventing these self-invented calamities. Since there is no ‘Undo’ button in life, it calls for some out of the box thinking and putting self-restraints on some deep-rooted human habits, to be able to set aside these ill effects our past misdeeds.</p><p> </p><p>The vast amount of water, which comprises our oceans, plays a crucial role in stabilizing the climate, making our earth’s atmosphere hospitable for human life. Land which is closer to the ocean is subject to more frequent shifts in weather, however, water acts as an environmental shock absorber.</p><p> </p><p>Teaching Earth Sciences at middle school level is an opportunity to make projects on Flash floods and carry it out by complex analysis of the rain gauge, geological, geophysical, predictive, diagnostic, descriptive and geodetic information available.</p><p> </p><p>Students work in small groups of 4-5 and find out information about local weather and climatic conditions, together with the river basin geography and geology as part of computer-generated models to simulate combinations of conditions to see the impact on water level. What they learn is applied to the design of data structures to control flood waters. They also find out about disastrous flash floods, lists and map them out, by year or by location. It’s involves a multidisciplinary approach as they write a report on it in their language subjects (Hindi and English), find the ways to control it (Science), location, mapping and affected area (Geography).</p>
