Abstract: The field of applied scientific research is important for the health, welfare and security of all countries in the world. Applied research scientists should be involved in the education of new generations of investigators. Institutions can reward them for such participation. It is well known that science fairs only reward a few winners and hundreds of others are left with no reward and possibly less inspiration to continue in science. In fact, Finland was ranked at the top in the U.N. World Happiness Report primarily because it aims not to leave any student behind, instead of only nurturing high achievers. This paper is intended to interest applied research scientists in the education of new generations of prospective applied researchers by presenting programs that do not leave any interested students behind. As presented in a National Science Teaching Association Commentary, by Steve Oppenheimer read by hundreds of thousands in the education community, and in a National Science Foundation webinar, this paper for the first time brings 2 key programs to applied scientists. One is a journal, whose 25 annual volumes inspire all students. The other is a symposium that does the same. The concept of science research for all students helped Steve Oppenheimer, win a U.S. Presidential Award for mentoring (PAESMEM), presented at the White House by President Obama. The American Association for the Advancement of Science (AAAS) cited Steve’s work with K-12 programs, as well as his glycobiology research, in his election as Fellow AAAS. In the journal and symposium there are only rare rejections. Problem submissions are corrected. The late Nobel laureate Francis Crick, who believed in the motto of science research for all, was an early collaborator in these programs. These programs can be easily replicated, especially with the involvement of applied research scientists, who in partnership with the education community, can interest many more students in applied research science. The involvement of Dr. Crick attests to the importance of bringing research scientists into these training programs. Many universities and organizations will count mentoring involvement in evaluating scientists for tenure and promotion.

Abstract: This paper studied the effects of tilt angles on the thermal performance of a solar parabolic collector system. This is the angle at which the beam solar radiation arriving from the sun will fall perpendicular to the solar collector surface. The quantitative assessments of radiation incident on a tilted plane are very important for designing solar collecting devices. The idea was to evaluate the thermal performance of the solar collector at the monthly optimal tilt angles in Bauchi (latitude 10°30’ North and 10°00’ East). Monthly mean daily global and diffuse components of the solar radiation for 10 years (January, 2009-December, 2019) were collected and used for the simulation using MATLAB software. Also used for the simulation are the developed energy balance equations for evaluation of thermal performances of solar collector. It was observed that, as the tilt angles decreases, both absorber tube and fluid temperatures together with the thermal efficiencies of the collector increased. Higher tilt angles were witnessed during January-February and September-December (20°-33°) and these months were having low temperatures of the absorber tube and the fluid (169°C-228°C and 130°C-117°C respectively). Low tilt angles between March to August (7°-16°) and with temperatures of the absorber tube and fluid between 220°C-235°C and 128°C-142°C respectively. Maximum thermal efficiency of 73% was obtained at the least optimal tilt angles (7°-8°). Thus, for efficient solar radiation collections, solar parabolic trough collector system should be maintained at optimal tilt angles between 7°-33° in Bauchi depending upon the seasonal variations.
