Row Crop Drip Irrigation On Bell Peppers Study, Charles M. Burt, Stuart Styles

BioResource and Agricultural Engineering

Underwood Ranches, located near Oxnard, installed a buried drip system on 50 acres of peppers in 1993. The amount of the CEC loan was $50,000.

The buried drip system provided sufficient advantages in water management, energy savings, and yield increases to convince the farm to expand its drip acreage to 140 acres in June 1995, and 320 acres in Sept. 1996. The farmer was an ideal cooperator.

The primary lessons learned on this project were:

• A grower needs approximately two years of experience and technical assistance in order to feel comfortable with a buried drip system. Even after that time, …

Row Crop Drip Irrigation On Peppers Study, Charles M. Burt, Stuart Styles

BioResource and Agricultural Engineering

High Rise Farms, located just north of Morgan Hill installed a new buried row crop drip irrigation system in 1993. The amount of the CEC loan was $42,700.

The installation of the drip irrigation system on the Peppers did provide significant improvements in the amount of water use, energy required and yield increases especially in the first year of operation (1993) and the third year of operation (1995). The second year of the project (1994) did not have yield increases. The primary lessons learned from this project included:

• The yield differential between drip and the furrow irrigation methods was attributed …

Pulsed Transient Tissue Conductivity Measurement, Robert B. Szlavik, Hubert De Bruin

Biomedical Engineering

The authors present an alternative technique for obtaining tissue conductivity as a function of frequency. Pulsed transient tissue impedance measurement differs significantly from other commonly used swept frequency techniques in that the conductivity of a tissue sample can be obtained from a voltage transient response to a current pulse. By obtaining the conductivity across a band of frequencies from a transient measurement, the necessity for direct conductivity measurements at each frequency point is eliminated. Calibration and verification of the technique was carried out by measuring the impedance magnitude and phase of simple RC circuit combinations. The authors present conductivity measurements …

Azorhizobium Caulinodans Uses Both Cytochrome Bd (Quinol) And Cytochrome Cbb3 (Cytochrome C) Terminal Oxidases For Symbiotic N2 Fixation, Alexandre Kaminski, Christopher L. Kitts, Zachary Zimmerman, Robert A. Ludwig

Biological Sciences

Azorhizobium caulinodans employs both cytochrome bd (cytbd; quinol oxidase) and cytcbb3 (cytc oxidase) as terminal oxidases in environments with very low O2 concentrations. To investigate physiological roles of these two terminal oxidases both in microaerobic culture and in symbiosis, knockout mutants were constructed. As evidenced by visible absorbance spectra taken from mutant bacteria carrying perfect gene replacements, both the cytbd- and cytcbb3- mutations were null alleles. In aerobic culture under 2% O2 atmosphere, Azorhizobium cytbd- and cytcbb3- single mutants both fixed N2 at 70 to 90% of wild-type rates; in root nodule symbiosis, both single mutants fixed N2 at 50% …

The Current Energy Situation: Summary Points, David W. Hafemeister, A. Brecher, A. Fainberg, R. Howes, R. Socolow, D. Bodansky, P. Craig, B. Hammer, S. Smith, E. Stechel

Physics

Energy problems are now being largely ignored, despite their continuing importance. The near-disappearance of energy from the U.S. public agenda is apparent in the scant attention given to energy topics by the media and by public figures. Some suggestions for governmental action were stimulated by the rise in gasoline prices in the Spring of 1996, but the matter was treated as a short-term anomaly -- not as a harbinger of more severe difficulties to come. This lack of long term concern is perhaps natural, because fuel supplies are generally ample and prices are still relatively low, with the real cost …

Child Development: Vulnerability And Resilience, Patrice L. Engle, Sarah Castle, Purnima Menon

Psychology and Child Development

Many of the challenges facing children now are a function of changing times, including increase in urbanization, political violence, changing family forms, and in some areas decreased supplies of adequate food. This review focuses particularly on those changes in which children are the victims and which induce new threats for them, rather than on problems such as child disability or mental illness. The outcome variables of interest in this paper are dimensions of children's psychosocial development, including cognitive development, psychological adjustment and aggression, whereas the companion paper in this issue (Caldwell P., Child survival: vulnerability and resilience in adversity in …

Integrating Multidisciplinary Design In An Undergraduate Curriculum, Russell M. Cummings, H. Jo Anne Freeman

Aerospace Engineering

Multidisciplinary design and analysis has become the normal mode of operation within most aerospace companies, but the impact of these changes have largely not been reflected at many universities. In an effort to determine if the emergence of multidisciplinary design concepts should influence engineering curricula, NASA has asked several universities (Virginia Tech, Georgia Tech, Clemson, BYU, and Cal Poly) to investigate the practicality of introducing the concepts within their undergraduate curricula. A multidisciplinary team of faculty, students, and industry partners evaluated the aeronautical engineering curriculum at Cal Poly. A variety of ways were found to introduce multidisciplinary themes into the …
