Liquid micrurgy chamber and microsyringe designs allow more efficient micromanipulations
More efficient micromanipulations on large amoebae achieved by liquid micrurgy chamber and microsyringe. These innovations move the system closer to the specimen, and flatten the specimen for a clear view of the nuclei, also eliminating spherical abberation and evaporation
Stratification of centrifuged amoeba nuclei investigated by electron microscopy
Study establishes a relationship between radioresistance and the nucleolar stratification characteristics of various amoeba species. Two species of fresh water amoeba are studied with the electron microscope. The report discusses the nature of nucleolar layers and their possible relationship to the differences in radiosensitivity of the two amoeba species
Employer-Sponsored Pensions: A Primer
The shifting pension landscape raises questions about the financial security of future retirees. About one-half of private-sector workers are not covered by employer-sponsored pension plans on their current job. Many private-sector employers have replaced traditional pensions with 401(k)-type plans, which protect benefits for workers who change jobs frequently but expose participants to investment risks. This primer describes pensions, workers with coverage, and related policy issues
Certain Aspects of the Status of Instructional Television in Elementary and Secondary Schools in the State of Utah
The primary purpose of the study was to determine the level of teacher competence concerning instructional television and the need for university training for future teachers. The secondary purpose of the study was to determine the availability, accessibility and utilization of instructional television equipment in elementary and secondary schools in the State of Utah. The principals of 400 elementary and secondary schools were the respondents in this study. A questionnaire was designed to acquire information on the following: (1) What degree of sophistication and types of television equipment are presently available in schools in the State of Utah; (2) what major problems are encountered by teachers using television; and (3) are the universities in the state adequately preparing teachers in the use of instructional television as an instructional medium. The results of the survey suggest that universities should offer prospective teachers hands-on experience in television utilization and production. An overwhelming majority of school principals (91 percent) indicated that universities should be doing this job. The results indicated what type of and how much equipment Utah schools presently have. In addition the survey showed the type of productions and programs that teachers are presently doing with television equipment. The results also identified several specific problem areas teachers now have
