The ~1 Myr history of the Purico-Chascon volcanic complex (PCVC) records significant changes in the production and storage of magmas in the crust. At ~1 Ma activity at the PCVC initiated with the eruption of a large 80-100 km³ crystal-rich dacite ignimbrite with restricted whole rock ⁸⁷Sr/⁸⁶Sr isotope ratios between...
Characiform fishes form one of the most diverse freshwater fish clades in the world. Comprising more than 2000 species and distributed primarily in South America and Africa, characiforms vary dramatically in their ecomorphology. However, the evolutionary processes responsible for the immense ecomorphological diversity remains unknown. Recently, a study postulated that...
Burnout, a problem that relates to an individual's occupation or vocational life, is a prolonged manifestation of emotional exhaustion, cynicism related to work, physical ailments, and reduced accomplishment of work tasks. Recently, the literature has shown that faculty in higher education experience Burnout as do other professions.
However, there is...
Two studies were conducted to determine the effects of zinc (Zn), copper (Cu) and/or selenium (Se) on the humoral immune response of weaned steers fed diets deficient in these minerals. Steers were bled weekly for eight weeks to measure plasma mineral levels. Humoral immune response was measured as antibody response...
There has been a large increase in the number of three-phase
diagnostic x-ray systems installed in hospital special-procedure rooms
during the last decade. The reason for this is the capability of three-phase
systems of making possible the very short exposure times and
increased tube loading required for some of the...

Professional development is a critical part of education, especially in career and technical education (CTE). CTE programs have rapidly changing technological foundations, and while the CTE teachers' primary focus is to prepare students for entry-level positions in their occupational areas, CTE teachers are also required to embed academics into their...
Recently the independent multinomial selections model (IMS) with the
multinomial logit link has been suggested as an analysis tool for radio-telemetry
habitat selection data. This model assumes independence between animals,
independence between sightings within an animal, and identical multinomial habitat
selection probabilities for all animals.
We propose two generalizations to...
In many statistical applications an interval is needed that will contain the values of all J future observations with some preassigned probability. For example, suppose twenty rockets have been fired in a test program and three have failed. If two more test programs are to be conducted, an interval that...
The spectrophone method for the study of vibrational relaxation
has been claimed to possess a distinct advantage over the more commonly

elementary statistics, progressive vector diagrams, coordinate system
independent spectra, and...
The classical dimension theories of Menger-Urysohn and Lebesgue are equivalent on metric spaces. However, their infinite-dimensional analogues may differ, even on compact metric spaces. The three such infinite-dimensional dimension theories considered in this thesis are known as countable-dimensionality, property C, and weak infinite-dimensionality. The open questions regarding the relationships between...
The study examined classroom instructional practices and teacher's
professed conceptions about teaching and learning college calculus in
relationship to the implementation of scientific-programmable-graphics (SPG)

project. The participants were not the catalysts seeking to implement calculus
reform, but expressed...
Incubation experiments with an acid poorly drained soil have
shown that the application of neutral soluble salts influenced the level
of extractable Mn. The application of a salt which lowered the soil
pH either increased the extractable Mn or retarded the oxidation
