Collisions and Spirals of Loewner Traces
We analyze Loewner traces driven by functions asymptotic to K\sqrt{1-t}. We
prove a stability result when K is not 4 and show that K=4 can lead to non
locally connected hulls. As a consequence, we obtain a driving term \lambda(t)
so that the hulls driven by K\lambda(t) are generated by a continuous curve for
all K > 0 with K not equal to 4 but not when K = 4, so that the space of
driving terms with continuous traces is not convex. As a byproduct, we obtain
an explicit construction of the traces driven by K\sqrt{1-t} and a conceptual
proof of the corresponding results of Kager, Nienhuis and Kadanoff,

Diurnal periodicity of activity in the spawning perch P. fluviatilis L. [Translation from: Kalamies 1972(7) 3, 1972]
Diurnal periodicity of spawning in the perch so far are rather meagre and found to be partly contrary to experiences of perch anglers. Therefore a study was made on the spawning during a 5-day period in the spring of 1971 in the Kuusamo area. Observations were made during the main spawning season, between 4- 9 June 1971. The perch were often measured, weighed and then released back into the water. The differences between spawning and non-spawning perch were studied as well as the time of roe discharge in a 24 hour period. Activity and environmental factors such as light intensity were also taken into consideration
Transgendered in Alaska: Navigating the Changing Legal Landscape for Change in Gender Petitions
Background: Detecting intracellular bacterial symbionts can be challenging when they persist at very low densities. Wolbachia, a widespread bacterial endosymbiont of invertebrates, is particularly challenging. Although it persists at high titers in many species, in others its densities are far below the detection limit of classic end-point Polymerase Chain Reaction (PCR). These low-titer infections can be reliably detected by combining PCR with DNA hybridization, but less elaborate strategies based on end-point PCR alone have proven less sensitive or less general. Results: We introduce a multicopy PCR target that allows fast and reliable detection of A-supergroup Wolbachia -even at low infection titers -with standard end-point PCR. The target is a multicopy motif (designated ARM: A-supergroup repeat motif) discovered in the genome of wMel (the Wolbachia in Drosophila melanogaster). ARM is found in at least seven other Wolbachia A-supergroup strains infecting various Drosophila, the wasp Muscidifurax and the tsetse fly Glossina. We demonstrate that end-point PCR targeting ARM can reliably detect both high-and low-titer Wolbachia infections in Drosophila, Glossina and interspecific hybrids. Conclusions: Simple end-point PCR of ARM facilitates detection of low-titer Wolbachia A-supergroup infections. Detecting these infections previously required more elaborate procedures. Our ARM target seems to be a general feature of Wolbachia A-supergroup genomes, unlike other multicopy markers such as insertion sequences (IS)
A Survey to Determine the Potential Training Stations Available For Distributive Education Students in Logan, Utah
All youth need to develop salable skills and those understandings and attitudes that make the worker an intelligent and productive participant in economic life. To this end , most youth need supervised work experience as well as education in the skills and knowledge of their occupations.
Education is considered by many philosophers to be the vehicle through which society achieves the goals it believes to be significant. The cooperative distributive education program is one of the vehicles that educators have created.
The first statement points out the need for supervised work experience as a part of America\u27s educational program. The second quotation illustrates a program of distributive education which educators have created to meet this need .
During the summer of 1967, Dr. Theodore Ivarie, Jr ., Head of the Department of Business Education and Office Administration at Utah State University, suggested that a community survey of the Logan , Utah, business firms to determine potential training stations for distributive education students would be of value to those concerned with the present and future development of cooperative distributive education programs in the Logan area. With Dr. Ivarie acting as an advisor, the proposal reflected in this chapter was prepared.
In October 1967, a meeting was held in Logan, Utah , involving Sherman Eyre, Superintendent of Logan City School District ; Leo G. Johnson, Principal of Logan High School ; J . Paul Hiller, Vocational Education Director of Logan High School; Dr. Charles Winn and John F. Stephens. The purpose of the meeting was to discuss the feasibility of adding a cooperative distributive education program to Logan High School \u27 s curriculum . I n the meeting it was pointed out that a distributive education program was functioning successfully at Sky View High School , Smithfield, Utah , ten miles from Logan. This proposal for a survey of Logan business firms to determine potential training stations for students enrolled i n a cooperative distributive education program was discussed. All of those present at the meeting agreed that the survey would be a needed and useful measurement of the distributive education training opportunities in the Logan area
