Tagging mortality experiments on Pacific mackerel, Pneumatophorus japonicus

Two experiments were conducted to compare tagging mortality rates when Pacific mackerel are tagged using a traditional method and a modified method. Tagged and control fish in equal numbers were held in tanks on board the R/V ALASKA and observed for mortality. The experiments revealed mortality rates of 24% when the tag passes between the pterygiophores or neural spines and 1.5% when the tag is placed in the lateral musculature. Mortality from handling the fish for tagging was 4%, tank trauma was 2%, and the initial tag loss was 2.5%. (20pp.

The Core Virtue of Christian Librarianship

Christian librarians should derive their professional ethics from methodical exegesis of the Bible. The New Testament\u27s most salient ethical statements center on love-for God, neighbor, and fellow believers. Each of these has significant implications for library practice. Identifying love as the core virtue of librarianship represents a radical departure from secular approaches to library ethics. While the biblical and secular models converge on some significant points, they are fundamentally opposite. Where the two reach similar conclusions, the biblical model proves to be more philosophically consistent. The Scriptures speak with enduring relevance to the issues facing librarians

Stellar Evolution Models of Young Stars: Progress and Limitations

Stellar evolution models are a cornerstone of young star astrophysics, which necessitates that they yield accurate and reliable predictions of stellar properties. Here, I review the current performance of stellar evolution models against young astrophysical benchmarks and highlight recent progress incorporating non-standard physics, such as magnetic field and starspots, to explain observed deficiencies. While addition of these physical processes leads to improved agreement between models and observations, there are several fundamental limitations in our understanding about how these physical processes operate. These limitations inhibit our ability to form a coherent picture of the essential physics needed to accurately compute young stellar models, but provide rich avenues for further exploration.Comment: 6 pages, 1 figure, to appear in proceedings of IAU Symposium 314: Young Stars and Planets Near the Su

Eclipsing binary systems as tests of low-mass stellar evolution theory

Stellar fundamental properties (masses, radii, effective temperatures) can be extracted from observations of eclipsing binary systems with remarkable precision, often better than 2%. Such precise measurements afford us the opportunity to confront the validity of basic predictions of stellar evolution theory, such as the mass-radius relationship. A brief historical overview of confrontations between stellar models and data from eclipsing binaries is given, highlighting key results and physical insight that have led directly to our present understanding. The current paradigm that standard stellar evolution theory is insufficient to describe the most basic relation, that of a star's mass to its radius, along the main sequence is then described. Departures of theoretical expectations from empirical data, however, provide a rich opportunity to explore various physical solutions, improving our understanding of important stellar astrophysical processes.Comment: 9 pages, 2 figures.
