Interactions between ecosystem nitrogen and bedrock control long-term calcium sources in Oregon Coast Range forests

Creator:: Hynicka, Justin D.
Abstract:: Ecosystem nitrogen (N) supply strongly influences the availability and cycling of other essential nutrients in temperate forests, especially calcium (Ca). Short-term additions of N that exceed ecosystem demands often increase dissolved nitrate fluxes and decrease soil pH, which can stimulate soil Ca loss. However, the long-term effects of high N...

Forest calcium depletion and biotic retention along a soil nitrogen gradient

Creator:: Perakis, Steven S., Sinkhorn, Emily R., Catricala, Christina E., Bullen, Thomas D., Fitzpatrick, John A., Hynicka, Justin D., and Cromack, Kermit, Jr.
Abstract:: High nitrogen (N) accumulation in terrestrial ecosystems can shift patterns of nutrient limitation and deficiency beyond N toward other nutrients, most notably phosphorus (P) and base cations (calcium [Ca], magnesium [Mg], and potassium [K]). We examined how naturally high N accumulation from a legacy of symbiotic N fixation shaped P...

Development of an enzyme linked immunosorbent assay (ELISA) for the detection of Zebrafish Interleukin 1 beta upregulation

Creator:: Cook, Samuel A.
Abstract:: The study and utilization of Danio rerio (Zebrafish) as a model organism has increased greatly in recent decades. They are used in many areas of biological research, but one field that has used them extensively is immunology. Since zebrafish have been found to possess many orthologs to human genes, study...

The Fully-Coupled One-Dimensional Arctic Surface Energy Budget: Climatology and Projections

Creator:: Kula, Michael R.
Abstract:: Arctic sea ice concentration and volume have declined due to greenhouse gas radiative forcing and an overall positive climate feedback. At the same time, there have been noteworthy weather and climate circulation anomalies both within the Arctic and extending through the midlatitudes and even into the tropics, leading some studies...

Effects of Elevated Temperature on Mycobacterium chelonae Growth and Mycobacteriosis in Zebrafish (Danio rerio)

Creator:: Lopez, Elizanette V.
Abstract:: Utilization of zebrafish, Danio rerio, has steadily increased and its applications have expanded into numerous fields of science. Applying elevated temperatures (32°C to 37°C) to this organism has allowed researchers to conduct climate change, human cancer and infectious disease studies. Though zebrafish can be acclimated from the standard 28°C to...

Impurity effect on magnetism of nickel for under bump metallization via magnetron sputtering

Creator:: Ong, Justin B.
Abstract:: Nickel or nickel alloys are common materials used in under bump metallization (UBM) in flip chip technology. Nickel is used because of its slow reaction rate with tin-based solder at elevated temperatures. However, nickel is ferromagnetic at room temperature, hence cannot be easily deposited with magnetron sputtering. In this study,...

Comparison of high and low tannin sorghum grain with low quality roughage for feeding ruminants

Creator:: Wanyama, Justin Mukami
Abstract:: Two studies were conducted to compare lamb feedlot performance and digestibility of nutrients by lambs fed rations containing bird-resistant and bird-susceptible sorghum grain with 20 or 40% tall fescue hay as a source of roughage. Four rations were fed ad libitum on the performance study and at 80% of ad...

Understanding School Counselors' Perceptions of Esports and Igaming as a Career Choice

Creator:: Cole, Justin D.
Abstract:: Over the past 20 years, there has been a steady increase in the popularity of online gaming in the United States culture. There are many factors that have contributed to this spike in popularity, but the most significant are advancements in technology, televised competitions, social media, lucrative cash prizes, product...

Load Path Investigation in a Light-Frame Wood House with Complex Geometry

Creator:: Holman, Justin D.
Abstract:: The objective of this study was to investigate load paths in an existing light-frame wood structure with complex geometry, using previously established computer modeling methods. The structural model is derived from an existing, multi-level residence located in Corvallis, Oregon. For the purpose of this study, the existing structure was simplified...

Litter controls of microbial community composition and function in forest soils

Creator:: Brant, Justin B.
Abstract:: Most carbon (C) transformations in soil are carried out by a diverse and complex soil microbial community. The size and composition of the soil microbial community is determined by poorly understood interactions between the quantity and chemical composition of plant inputs, as well as climate. Given the metabolic diversity of...
