Microwave switching power divider

A pair of parallel, spaced-apart circular ground planes define a microwave cavity with multi-port microwave power distributing switching circuitry formed on opposite sides of a thin circular dielectric substrate disposed between the ground planes. The power distributing circuitry includes a conductive disk located at the center of the substrate and connected to a source of microwave energy. A high speed, low insertion loss switching diode and a dc blocking capacitor are connected in series between the outer end of a transmission line and an output port. A high impedance, microwave blocking dc bias choke is connected between each switching diode and a source of switching current. The switching source forward biases the diodes to couple microwave energy from the conductive disk to selected output ports and, to associated antenna elements connected to the output ports to form a synthesized antenna pattern

Utilizing cow-calf producer information to increase profits in retained ownership of beef cattle

Retained ownership has been found to be a profitable endeavor, yet many cow-calf producers choose not to retain their calves. While this paper does not directly explore the reasons producers might have for not retaining ownership, which may include uncertainty, it does explore innovative use of asymmetrical information that might reduce some of the uncertainty. Results are summarized in a regression analysis similar to a Hedonic price model where birth weight, weaning weight, and weaning age are found to be important factors to consider when selecting animals to retain.Asymmetrical Information, Hedonic Price Model, Beef, Retained Ownership, Producer Profitability, Farm Management, Livestock Production/Industries, Production Economics, D82, M31, Q13,

The Dictator of Dearborn

This is a book review of Orvie: Dictator of Dearborn by David Good. The book focuses upon the long-term mayor of Dearborn, Michigan. He was know for his efficient administrative services, his exceptional personal popularity, his abusive administrative style, his controversial personality, and his segregationist views.http://deepblue.lib.umich.edu/bitstream/2027.42/110668/1/HubbardReviewOfGood.pdfDescription of HubbardReviewOfGood.pdf : Main articl

Deep Spectroscopy in the Field of 3C 212

We present the results of longslit and multiaperture spectroscopy of faint galaxies in the field of the z=1.049 quasar 3C212. We show that an apparently aligned optical feature beyond the NW radio lobe has a redshift z=0.928, and a similarly aligned feature just beyond the SE radio lobe has a redshift z=1.053, quite close to that of the quasar. While the NW optical component is extremely well aligned with the radio jet and has a morphology that is very similar to that of the radio lobe lying 3" interior to it, the fact that we find three other field galaxies with closely similar redshifts indicates that it is most likely a member of an intervening group rather than an unusual example of true alignment with the radio structure. In addition, we have found two galaxies (besides the one near the SE radio lobe) having redshifts close to that of 3C212. We have firm or probable redshifts for 66 out of 82 galaxies we have observed in this field. Comparison with the redshift distribution of faint field galaxies indicates that a large fraction of the remaining 16 galaxies are likely to be at redshifts >1.4. There are at least two low-redshift dwarf starburst galaxies showing low metal abundance and high ionization in our sample; such galaxies are likely to be relatively common in very faint samples, and, under certain conditions, they could be confused with high-redshift objects.Comment: 15 pages, 4 figures, one of which is a separate JPEG plate.

Response to Hanan Ashrawi

This is a talk delivered to the Cranbrook Peace Foundation in 2005. They had given their annual peace award to Palestinian negotiator Hanan Ashrawi. There were two speakers who responded to her talk, one an Israeli who had monitored her while in the miitary, one myself.http://deepblue.lib.umich.edu/bitstream/2027.42/110674/1/Ashrawi2005.pd
