Computerized polar plots by a cathode ray tube/grid overlay method

Overlay is aligned with four calibration dots so it is not affected by CRT drift or changes in vertical or horizontal gain when producing Nyquist /frequency-response phase/amplitude/ plots. Method produces over 50 plots per hour

Dear God

Dear God, Okay, first, full disclosure: I don’t believe You are a You. Of course, if I’m wrong and You are a You, You already know this—and everything else, for that matter. And if You really are the all powerful You so many people imagine, the one with long white hair sitting on a throne in heaven (wherever that is), maybe You’ve got Your finger raised right now, pondering whether to unleash that lightning bolt and smite me for being insubordinate.https://digitalcommons.butler.edu/onearth/1045/thumbnail.jp

Both The Book of Ruth and A Map of the World have been selections of Oprah\u27s Book Club. The Short History of a Prince was a Publishers Weekly Best Book of 1998; her novel Disobedience was published in 2000; When Madeline Was Young was a Washington Post Best Book of 2006. She lives and writes in an orchard farmhouse in Wisconsin.In March 2009, Hamilton was a writer-in-residence at Butler University. This conversation with novelist Barbara Shoup about her book When Madeline Was Young and the newly released Laura Rider\u27s Masterpiece took place before a group of students in Professor Susan Neville\u27s Visiting Writers Series class

Effects of gestational energy source on feedlot performance, glucose tolerance, and carcass traits of progeny

Effects of maternal energy source during gestation on postnatal growth and metabolism of progeny has not been well described. The objectives of this experiment were to determine the effects of hay (HAY), corn (CORN), or dried distillers grains (DDGS) fed to cows in late-gestation on progeny post-weaning growth, glucose tolerance, and carcass characteristics. Angus-cross cows (n = 84; BW = 620 ± 12 kg) were blocked by BW and allotted to 4 pens per treatment. Dietary treatments were fed at isocaloric intakes from 155 to 272 d of gestation. Following parturition, cows and calves were fed and managed as 1 group. Post-weaning, steers (n = 27) and heifers (n = 27) were transported to the feedlot, housed in individual pens, and fed a common diet which contained 50% cracked corn, 20% DDGS, 15% corn silage, and 15% supplement (DM basis). A glucose tolerance test (GTT) was conducted on calves (n = 12) on d 41 and d 111 after feedlot arrival and blood samples (n = 7) from each calf were collected from 5 to 120 min post-glucose intravenous infusion (0.25 g of glucose/kg of BW). Calves were slaughtered at a 12th rib fat thickness of 1.2 ± 0.05 cm as determined via ultrasound. Gestational diet did not affect (P ≥ 0.30) progeny feedlot performance (initial BW, final BW, DMI, ADG, or G:F). During the GTT, fasting concentration and area under the curve (AUC) for glucose and insulin were not affected (P ≥ 0.47) by treatment. Glucose clearance rate was greater (P = 0.01) in progeny from dams fed CORN than progeny from dams fed HAY or DDGS. Initial insulin response was greatest to least (P < 0.01) for calves from cows fed CORN, DDGS, and HAY, respectively. Fasting insulin, insulin AUC, glucose AUC, and glucose clearance rate were all greater (P < 0.01) on d 111 than d 41. There were no differences (P ≥ 0.33) among treatments for carcass characteristics. Gestational energy source did not affect feedlot performance or carcass traits; however, it did affect glucose clearance rate and initial insulin response. Days on feed increased insulin resistance and decreased glucose tolerance when cattle were fed a high-grain diet.No embarg

Uncertainty in Multi-Commodity Routing Networks: When does it help?

We study the equilibrium behavior in a multi-commodity selfish routing game with many types of uncertain users where each user over- or under-estimates their congestion costs by a multiplicative factor. Surprisingly, we find that uncertainties in different directions have qualitatively distinct impacts on equilibria. Namely, contrary to the usual notion that uncertainty increases inefficiencies, network congestion actually decreases when users over-estimate their costs. On the other hand, under-estimation of costs leads to increased congestion. We apply these results to urban transportation networks, where drivers have different estimates about the cost of congestion. In light of the dynamic pricing policies aimed at tackling congestion, our results indicate that users' perception of these prices can significantly impact the policy's efficacy, and "caution in the face of uncertainty" leads to favorable network conditions.Comment: Currently under revie

Arte mural tradicional en Walata: ciudad caravana en el Hawdh oriental

Walata is one of the major caravan cities in the southern Sahara located on the route from Timbuktu to the northern cities of either Sijilmassa in the Tafilalt oasis or Nul Lamta on Wadi Nun. The city has a long history stretching back to before it was named Walata which archeology has only recently (2004) begun to investigate. The city is justly famous for the unique wall art on its houses. The art is the realm of women who have passed it on from generation to generation. Local oral history states the wall art found in Walata dates to al-Murabitin period (11th century) when a number of Muslims from al-Andalus were exiled there. The wall art of Walata is unique not only to its own region of the Hawdh in eastern Mauritania, but to the whole Sahara. The art can be divided into three main types: around the main street entrance to the house, walls of the interior courtyard, and the inside of rooms. The designs are subject to change over time and recently new ones have been introduced from henna for the hands, straw mats, and Moroccan carpets while some of the older designs are no longer being done.Walata es una de las mayores ciudades caravana en el Sahara septentrional emplazada en el camino desde Timbuktu a las ciudades norteñas de Sijilmassa en el oasis de Tafilalt o a Nul Lamta en Wadi Nun. La ciudad tiene una larga historia que se remonta a antes de que fuera llamada Walata, que la arqueología ha empezado a investigar recientemente (2004). La ciudad es en concreto famosa por el singular arte mural de sus casas. Este arte se da en la esfera de las mujeres, que lo conservan de generación en generación. La tradición oral local establece que el arte mural que se encuentra en Walata data del periodo al-Murabitin (siglo XI), durante el que unos cuantos musulmanes de alÁndalus se exiliaron en la zona. El arte mural de Walata es único no sólo en la región de Hawdh, en Mauritania oriental, sino también en el Sahara en su totalidad. Este arte puede dividirse en tres tipos principales: en las entradas de las casas alrededor de la calle principal. en los muros del patio interior, y en el interior de las habitaciones. Los diseños pueden cambiar a lo largo del tiempo y recientemente se han introducido nuevos inspirados en la henna de las manos, en las esteras de paja, y en las alfombras marroquíes, mientras que algunos de los más antiguos ya no se hacen
