Coral reefs, found in tropical regions, are renowned for their rich biodiversity and their contributions to ecological, cultural, and economic aspects worldwide. The success of coral reefs hinges on the symbiotic partnership between corals and their dinoflagellate algae, from the family Symbiodiniaceae. The algae reside within the coral host’s gastrodermal...
The purpose of this narrative inquiry study was to describe the lived experiences of librarians and how they provided support and innovation for community college OER programs. Examining the experiences of librarians as innovators sought to understanding how best practices developed for OER programs. It further sought to examine how...
During the peripartum period (3 weeks before through 3 weeks after calving, a.k.a. “transition”), high producing dairy cows experience, among others, , oxidative stress and immune suppression that compromise performance and increased incidence of diseases.Among trace minerals, supplementation of Selenium (Se) can help to improve the transition by enhancing glutathione...
Understanding the relationship between motivation, academic achievement, and persistence may help higher education administrators develop plans for increasing student engagement and student success. Prior research on higher education indicated connections between motivation, academic achievement, and persistence, but there has been limited research that relates these concepts to the rural community...
Porous carbon is indispensable in modern technology applications. It is used for energy storage, gas separation, water purification, catalyst support, and chromatography. The diversity of its applications stems from its unique properties, including high specific surface area, tunable pore volume, and chemical stability. Specifically, the large surface area provides high...
Several experiments involving broilers, chicks, layers, roosters,
poults and breeder turkeys were conducted with the primary objective
of examining research methods for evaluating poultry feed grains, their
additives and supplements. A secondary objective was to improve and
maximize the production responses of poultry fed locally grown grains.
Feed grain research...
The purposes of this investigation were: (l) To attempt to
determine how well programs of guidance services were felt to be
functioning in meeting the needs of pupils through an analysis of
guidance services in selected high schools in Oregon, and (2) To
develop recommendations for improving programs of guidance...
Agrobacterium tumefaciens is a common soil bacterium that causes crown gall
disease on many dicotyledonous plant species. It has been exploited for use in genetic
engineering because it is able to promote transfer of any DNA segment to plant
chromosomes. Many molecular factors in both the plant and bacterium contribute...
Pacific lamprey, Entosphenus tridentatus, have shown recent and rapid declines in abundance. These anadromous fish return to streams where they mature, spawn and die. It has been inferred that Pacific lamprey enter freshwater and reside for ~ 1 year before spawning. This long exposure to the freshwater environment may affect...
