The impact of science fair projects on student learning and mastery of nature of science objectives in 9th grade physical science The purpose of this study was to determine the impact science fair projects on student learning and mastery of Nature of Science objectives in 9th grade Pre-AP physica...
The pedagogical goal of the work is to empower students to realize and use connections between chemistry, physics, polymer science, and engineering to understand the process of material design and selection.Alexander H.GreerWilliam VauclainElijah LeeAidan LoweJared HoefnerNikhil ChakrabortyMichael Fair...
Trumpet players often suffer dizziness or black-outs when they play high notes. The pressure in the aperture that is required to produce a note causes the heart valves to collapse so blood cannot enter; consequently, the blood pressure drops. There is not enough blood flowing to the brain, s...
However, the extraction of nuclei from thick targets is chemistry dependent. Since refractory elements have extremely low volatility, their extraction is particularly difficult. Multi-nucleon transfer reactions (deep-inelastic) offer an alternative production mechanism to fragmentation/spallation. The large ...
Indeed, if such alchemy was possible, the impact on our daily life would be immense. One could then dream about production and enrichment of low-abundance elements or about changing waste composition, as well as about many other applications in astronomy, geology, biology, medicine, chemistry, ...
Coastal lagoons are one of six categories of inland coastal ocean-connected systems (Kjerfve 1994). Coastal lagoons are shallow water bodies, with depths usually less than 5 m, oriented parallel to the shoreline, separated from the ocean by a barrier, an

In particular, the authors performed the PEST analysis using the weighting performed by a panel of experts in the fields of Economics, Chemistry, Biology, and Geography. 2.1. PEST Analysis—Political Environment Table 1 contains the political determinants of the RE in the Pomerania region. The ...
antiproton ring (LEAR) with an estimated production rate of about 0.3 % to 0.7 % per annihilation [71,72] on Bi and U targets, respectively. Additionally, the future PANDA experiment at FAIR plans to investigate the production of double-\Lambdahypernuclei using a two-step reaction [73,74]...
