Abstract: This paper is for applied research scientists and any scientists who train students to do research. It consists of two parts: (1) an open door hands-on research training program that helped garner a US Presidential Award for Mentoring and election as Fellow, American Association for the Advancement of Science (AAAS); (2) a Covid-19 Pandemic virtual research training program that provides readings and You Tubes for the students followed by an opportunity to develop new research ideas. The co-authors of this paper are the students who pioneered the virtual program. In the hands-on program of 263 students who reported their career outcomes to Steve, 52 achieved doctoral degrees and became professors and researchers, 62 became M. D.s or M. D.-Ph. D.s, 33 became dentists, 17 pharmacists, 97 became scientists in research and/or education and 2 became lawyers. Many of the students co-authored lab published papers, abstracts and national poster presentations. The program’s success resulted from an open door policy that invited all interested students to try their hands at research, regardless of their grade point averages, and organizational components that recruited advanced students to help train new students. Universities and other organizations often look favorably on student mentoring in tenure and promotion decisions. Many students can possibly result in more good publications. Readers can determine, by examining the student co-authored papers in the reference section of this paper, if this expanded student-involved program leads to “good publications,” as AAAS and the NSF/White House review committee suggested it did.

Abstract: Warqe processing is carried out dominantly by women using traditional tools such as a bamboo scraper, serrated wooden tool and metal knife where losses in quality and quantity are exceptionally high. Above all, the traditional way of warqe processing causes physically drudgery among the rural women. In an effort to alleviate the problem, an engine is driven warqe decorticating machine was designed, constructed, tested and evaluated at field conditions. The performance evaluation of the machine was made in terms of decorticating capacity, decorticating efficiency, percentage pulp loss, and fuel consumption. The performance evaluation was carried out at three levels of drum speeds (850, 950 and 1050 rpm), concave clearances (1, 3 and 6 mm) and feeding rates (0.037, 0.056 and 0.074 kg/s, these are based on the feeding rates of 1.00, 1.50 and 2.00 kg/27s) to determine the optimum combination of the same. The experimental design laid was factorial, in the split-split plot. The maximum decorticating capacity of 255.38 kg/hr was obtained at a drum speed of 850 rpm, concave clearance of 1 mm and feeding rate of 0.074 kg/s. The decorticating efficiency and percentage un-decorticated pulp highly depended on concave clearance rather than other factors. Maximum decorticating efficiency 98.97% and minimum pulp loss of 1.03% were achieved at drum beater speed of 850 rpm and concave clearance of 1mm. The production cost of the decorticator was found to be 28,322.00 Birr. The total operating cost of the decorticator estimated to be, 48,925.38 Birr and the payback period and benefit-cost ratio of the prototype decorticating machine were estimated to be 0.90 years and 1.64, respectively.
