Data for temperature and leaf gas exchange of aquaponic lettuce
No full textThe CEA_Data.xlsx file contains 6 sheets containing thermo-gas and leaf canopy growth and moisture signatures. Sheet 1 (Perday) contains week no., day, humidity, temperature, O2 and CO2 concentrations outside and inside a partially diffused microclimatic chamber, net ecosystem exchange, photosynthetic quotient, and the produced O2 and assimilated CO2 for the light-dependent photosynthetic reaction. It also contains the week no., day, humidity, temperature, O2 and CO2 concentrations outside and inside the chamber, net ecosystem exchange, thermal sensitivity Q1, and the produced and assimilated CO2 and O2 during the dark-period respiration. Sheet 2 (GDD) contains temperature variances, growing degree day values, thermal ratio (max/min), and the photothermal unit. Sheet 3 (FMT_EWT) contains the measured and RNN-predicted full moisture content and equivalent water thickness as metrics of leaf moisture stress. Sheet 4 (PCSI) contains minor and major axis length and the resulting plant canopy shape index per plant from week 1 to week 6 of cultivation. Sheet 5 (VI) contains the RGB, MGVRI, GLI, MPRI, RGBVI, ExG, and VEG as optical vegetative stress indices. Sheet 6 (SUMMARY) contains the established parameter ranges for vegetative, head development, and harvest stages of aquaponic lettuce
Data for chlorophyll and anthocyanin dyes combination optimization using evolutionary computing
No full textThe uploaded file has six tabs pertaining to dye concentration optimization and characterizations. Tab 1 (AM1.5) presents the short-circuit current, open-circuit voltage, fill factor, efficiency, power, and cell resistance of the 9 fabricated DSSCs. Tab 2 (AM1.5 range) presents the photocurrent and power generated through voltage sweeping from -2 to 0 V. Tab 3 (Optimization) presents the characterization of selection rate, mutation rate, and crossover rate of genetic algorithm and evolutionary strategy in determining the fitness value and the best solution for green and violet dye concentrations that will give the maximum possible power efficiency. Tab 4 (FTIR) presents the raw data spectral analysis in the 4000 to 500 cm-1 range. Tab 5 (UV-Vis absorbance) presents the spectral absorbance of each dye combination without the optimization yield and the photon energy and absorption coefficient of dyes data. And Tab 6 (Stability) presents the 21-day stability test of pure green, pure violet, GA-based, and ES-based dyes without thermoplastic Surlyn jacket
Design of a Hypergravity Simulation Platform with Speed and Axis Stability Control Systems
No full textMaize root behavior as three-inputs-three-outputs logical gates due to positive gravitropism and nutritropism
No full textRoot growth and their interactions can provide valuable information for the development of asynchronous logic systems. Here, maize root behavior due to positive gravitropism and nutritropism is evaluated as three-inputs-three-outputs logical gates. Using plant roots as the element for unconventional computing, the Boolean functions of each root tropism were constructed through arithmetic-logical operations. One gravity gate (rGG) and two nutrient gates (rNG1 and rNG2) were fabricated using additive manufacturing. The rGG platform was oriented with roots directly pulled down by gravity which computes (x, y, z) = (xz + yz, x + y ̄z+yz ̄, xy + yz), whereas specific output channels in rNG1 and rNG2 were fertigated with high phosphorus concentration resulting in (x, y, z) = (x + y + z, xy + xz, xyz) for rNG1 and (x, y, z) = (xyz, xy ̄z+xyz ̄, x + y + z) for rNG2. For rGG, rNG1, and rNG2, the symbols x, y, and z pertain to "root presence" in the related channel, whereas top bar on the symbols indicates "root absence". Anatomical traits of roots were evaluated to assess possible differences in vascular tissues due to gravitropic and nutritropic responses. Overall, maize primary roots showed prominent positive gravitropism and nutritropism, and the roots that were most attracted by gravitational or nutritional stimuli showed an increase in the diameter of phloem and xylem. The logic exhibited by roots was dependent on the gravitropic and nutritropic stimuli to which they were exposed in the different logic gates. The responsiveness of maize roots to environmental stimuli such as gravity and nutrients provided valuable information to be used in computational bioelectronics
Sharon Hoilman and Ronnie Greene
No full textThis undated photograph shows Sharon Hoilman and Ronnie Greene of Cranberry High School. Founder and director of the Mountain Youth Jamboree, Hubert H. Hayes (1901-1964) auditioned and directed youth to perform in folk dance, music, and folk and ballad singing. The jamboree was held in the Asheville City Auditorium (now known as Thomas Wolfe Auditorium) from 1948 to 1973, and Hayes’ wife, Leona Trantham Hayes (1913-1989) continued to direct the program after his death in 1964. Hubert Hayes was an author, playwright, and alumni of Duke University
