Automorphisms and coverings of Klein surfaces
No full textIn this thesis the theory of automorphisms and coverings of compact Klein surfaces is discussed by considering a Klein surface as the orbit space of a non-Euclidean crystallographic group. In chapter 1 we set out some of the well-established theory concerning these ideas. In chapter 2 maximal automorphism groups of compact Klein surfaces without boundary are considered. We solve the problem of which groups PSL (2,q) act as maximal automorphism groups of non-orientable Klein surface without boundary. In chapter 3 we discuss cyclic groups acting as automorphism groups of compact Klein surfaces without boundary. It is shown that the maximum order for a cyclic group to be an automorphism group of a compact non-orientable Klein surface without boundary of genus g ?3 is 2g, if g is odd and 2 (g – 1) if g is even. Chapter 4 is the largest section of the thesis. It is concerned with coverings (possibly folded and ramified) of compact Klein surfaces, mainly Klein surfaces with boundary. All possible two-sheeted connected unramified covering surfaces of a Klein surface are classified and the orientability of a normal n-sheeted cover, for odd n, is determine

'n Herwaardering van die werk van Elise Muller
No full textBibliography: pages 161-168.Hierdie studie het gemik op 'n herwaardering van Elise Muller se bydrae tot die Afrikaanse letterkunde. Hennie Aucamp het met Elise Muller. Verhale en essays 1942-1981, die eerste stap tot herwaardering geneem ten opsigte van Elise Muller en haar prosawerk. So ook het Nel in haar skripsie met waardering gekyk na die bekende en haas onbekende werk van Muller. Hierdie nuwe kyk na die werk van Elise Muller word in die tesis verder gevoer. Dit poog om die onbekende, "ander" Elise Muller op die voorgrond te stel. Ten einde die "ander" Muller te belig, was dit nodig om te let op die tradisionele Muller. 'n Ondersoek na beide Muller se vernuwende en tradisionele bydrae tot die Afrikaanse letterkunde het dit duidelik laat blyk dat sy heel gebalanseerd en genuanseerd te werke gaan met die tradisionele Afrikaner ideologieë
[Letter from Helen Muller to T. N. Carswell - July 20, 1965]
No full textA letter written to Mr. T. N. Carswell, Abilene, Texas from Helen Muller, Panhandle Agricultural and Mechanical College, Office of the Registrar, Goodwell, Oklahoma, dated July 20, 1965. Muller expresses her appreciation for the letter from Carswell concerning Dr. Cyrus N. Ray and explains that she wrote to Ray but does not know him. She offers to help financially, if needed, and advises that Mr. Ambrose Ray of Lubbock should know Dr. Ray well due her understanding that their families visited

Chimpanzees and human evolution/ edited by Martin N. Muller, Richard W. Wrangham, and David R. Pilbeam.
No full textIncludes bibliographical references and index.Although chimpanzees and other primates are frequently used as models to reconstruct the behavior of extinct human ancestors, this is rarely done in a consistent or methodologically rigorous fashion. This volume brings together leading scholars to explore how knowledge about chimpanzees can be used to understand both what is unique about our own species, and how these traits evolved. The first part of the book makes the case that the last common ancestor of chimpanzees and humans was chimpanzee-like. This inference is based not on an assumption that chimpanzees are a model species, but on morphological, developmental, and genetic data, together with evidence from the hominin fossil record. The second part of the book provides the first detailed record of the similarities and differences between humans and chimpanzees, including those in social system, mating system, diet, social behavior, hunting, tool use, culture, cognition, and communication.--Martin N.

Hotel Klein [Bar and dining area]
No full textIllustrated colored postcard of Hotel Klein with a postmark date of September 6, 1916. Hotel Klein, at 12 Albany Street, was on the Lincoln Highway and was a stopping place for 20 to 30 bus lines. In 1937, the hotel was sold to Jacob Rosenberg, who reopened it as the Hotel Joyce Kilmer after extensive remodeling. Then in 1941, its name was changed to Rutgers House and for a time it served as quarters exclusively for Hercules Powder Company engineers and executives. It was owned by Frank Stepko of South River following the Rosenberg regime. The building gave way to the widening of Burnet Street to create Memorial Parkway in the 1953
Data from: Estimating agronomically relevant symbiotic N fixation in green manure breeding programs

(2021) Data from: Estimating agronomically relevant symbiotic N fixation in green manure breeding programs. [Dataset] Cornell University eCommons Repository. https://doi.org/10.7298/vrd4-4k23Widespread use of legume green manures is limited by a lack of reliable varieties that meet the needs of farmers. Improving symbiotic N fixation (SNF) in open-pollinated legume species poses a challenge because normal methods used for assessing SNF conflict with breeding practices such as seed production and removing low-quality sires. We investigated methods for measuring symbiotic N fixation that are compatible with breeding practice for two major legume cover crops: hairy vetch (Vicia villosa) and crimson clover (Trifolium incarnatum L.). We collected two non-destructive samples at the early-flowering stage (Meristem and Wedge) and a sample at seed harvest (Seed). Our objective was to determine which combination of measurements best predicted symbiotic N fixation (%Ndfa) and total N content at 50% flowering. Our statistical approach accommodated the problem that target traits and seed measurements cannot be measured in the same individuals. Overall, the Wedge sample provided the best prediction for Ndfa at 50% flowering. The best predictions for total N plant-1 came from combining vigor ratings with aboveground biomass at seed harvest. In addition to specific recommendations for legume cover crop breeding programs, we provide a flexible statistical method for studying relationships between traits that cannot be measured jointly.This work was supported by USDA-NIFA grant #2015-51300-24192, with additional support from USDA-NIFA grant #2018-51106-28778.
