\u3ci\u3ePrince Caspian\u3c/i\u3e and \u3ci\u3eChild Christopher and Goldilind the Fair\u3c/i\u3e

A look at the roots of Lewis’s Prince Caspian in William Morris’s Child Christopher and Goldilind the Fair (and in turn Morris’s source in Havelok the Dane) investigating the “imaginatively redemptive” changes Lewis made to this source material

Suggests that certain scenes from Wells’s First Men in the Moon inspired the Khazad-dûm episode in Fellowship of the Ring

Tolkien and Old Germanic Ethics

Claims the “idea that a warrior must die with his lord in battle is one of the most important moral injunctions among the various Germanic peoples.” Uses this theme to examine Tolkien’s work for his reworking of the Old Germanic ethic into a Christian perspective

The Face of the Materialist Magician: Lewis, Tolkien, and the Art of Crossing Perilous Streets

Plenary address, Mythcon 47. Concerns the character of the “Materialist Magician” (Screwtape’s term) in Tolkien and Lewis—the Janus-like figure who looks backward to magic and forward to scientism, without the moral core to reconcile his liminality. Tolkien’s Saruman and Lewis’s Uncle Andrew and Devine are key specimens of this trope, with Merlin standing as a counter-example

The effects of gonadotropin releasing hormone on conception in postpartum anestrus angus beef cows and heifers

The objective of this study was to determine if a pre synchronization gonadotropin releasing hormone (GnRH) injection would increase conception percentages in postpartum anestrous angus beef cows and heifers. Sixty-four Angus females (42 multiparous cows and 20 heifers) from the Angelo State University’s Management, Instruction and Research Center were randomly assigned to two treatments groups at the beginning of the study. The control group were administered a two shot prostaglandin estrous synchronization protocol. The treatment group were administered a GnRH injection thirteen days prior to the two shot prostaglandin synchronization protocol. However, only 30 females showed signs of estrus and were artificially inseminated. Results in cows and heifers were similar, and no differences were found among the two treatment groups (P>0.05). Differences might be noted with a larger number of females that show signs of estrus. Conception was recorded by the use of ultrasound, and is a viable management tool

Об определении оптимальных расстояний между разведочными выработками в связи с различными размерами участков и анизотропностью тел полезных ископаемых

The main challenge to address single emitters in a high-power diode-laser-bar is the thermal and electrical management to avoid crosstalking. Especially p-side up assembly leads to increasing thermal influence of neighboring emitters due to the low thermal conductivity of GaAs. Electro-magnetic fields inside and outside the laser-bar, for example caused by high frequency modulation (10 MHz) at a high current (up to 1 A), induce voltages into neighboring electrical circuits, hence the output power of neighboring emitters can be affected

Lewis’ Time Machine and His Trip to the Moon

Explores Lewis’s (acknowledged) debt to H.G. Wells’s First Men in the Moon for Out of the Silent Planet. Suggests that “we can only understand Lewis’ fragmentary The Dark Tower by noticing a similar debt to Wells’ The Time Machine.

Heterosis and Heterosis Retention for Reproductive and Maternal Traits in Brahman x Hereford Crossbred Cows

Calf crop born, calf crop weaned, calf birth weight, calf weaning weight, and cow weight at weaning were evaluated from 1996 to 2009 in Brahman (B) and Hereford (H) straightbred and crossbred cows (n = 1,515). The objective of these analyses was to estimate heterosis for F1 and F2 females for these reproductive and maternal traits. Breed groups included B, H, F1 Hereford-sired (HB) and Brahman-sired (BH) cows (n = 114 purebreds, 55 F1, 52 F2). Second generation breed groups included cows sired by HB and out of HB dams (F2HB) and BH dams (HBxBH); and cows sired by BH and out of HB dams (BHxHB) and BH dams (F2BH). Least squares means were calculated for calf crop born, calf crop weaned, and calf birth and weaning weights, using numerous different models, where the trait was the dependent variable. Previous research and these preliminary analyses showed that the effects of year and cow age are real as is their interaction each other and with breed type. In each attempted model designed to remove these effects, different breed groups received excessive adjustments, rendering the resultant heterosis estimates inappropriate. To more clearly assess differences, presentation and visual evaluation of unadjusted means were conducted. The model for mature cow weight (cows at 6 years of age) included breed group as fixed effects and cow within breed group and year as random effects. F2 cows appeared to retain approximately 39% of F1 heterosis for calf crop born and approximately 50% for calf crop weaned. HB x BH cows delivered the lightest calves at 33.9 (4.74) kg and F2BH had the heaviest calves at birth at 36.6 (5.37) kg. BH cows weaned the heaviest calves at 240.9 (38.1) kg and F2BH cows weaned the lightest calves at 208.4 (31.9) kg. Sire breed of calf and age of cow appear to be important factors regarding weight traits. Retained heterosis for cow weight at weaning was higher than expected at 73%. Sire breed group differences (HB vs. BH) for these traits in F2 cows may merit further investigation
