Influence of water hardness on gill accumulation and acute toxicity of aluminum in rainbow trout

Creator:: Bustaman, Sjahrul
Abstract:: Rainbow trout were exposed to aluminum at pH 7.25 and 8.25 and four hardnesses (10, 30, 80, and 120 ppm CaCO₃) for 96 hours in a continuous-flow system and mortality and aluminum accumulation in the gills were determined. Temperature, pH, and dissolved oxygen were measured daily for each treatment. Dissolved...

Soil compaction on a mechanized timber harvest operation in eastern Oregon

Creator:: Zaborske, Richard R.
Abstract:: The use of mechanized harvest equipment has been increasing as an economical method to harvest small diameter timber. While the use of this equipment is increasing, little is known about associated soil compaction. In particular, little information exists on soil compaction caused by feller--bunchers. This study measured soil compaction caused...

Shovel logging and soil compaction : a case study

Creator:: Floch, Rick F.
Abstract:: Shovel logging is a relatively new ground-based method of yarding tinther. It involves moving logs from stump to landing by successive swinging with a hydraulic excavator modified into a log loader by replacing the shovel bucket with a grapple. Loaders used in shovel yarding can weigh in excess of 100,000...

Reaeration in a turbulent stream system

Creator:: Ice, George G.
Abstract:: The oxygen concentration in a stream is an important parameter of water quality. Changes in oxygen concentrations can affect various stream organisms including fish. Foresters have become concerned with predicting the impacts of forest activities on oxygen levels in streams. Slash, which accumulates in streams as a result of harvesting...

Soil variability on steep, skeletal forested slopes of the Umpqua National Forest, Oregon

Creator:: Myhrum, Ronald P.
Abstract:: This study was undertaken to determine both the amount and the spatial variability of sand, silt, clay, and six fractions of coarse fragments in soils representing harsh sites for reforestation. Particle size data were collected because of their direct relationship to water holding capacity and the plantability and survivability of...

An evaluation of soil warming for increased crop production

Creator:: Rykbost, K. A.
Abstract:: In regions where soil temperatures limit plant growth, artificial soil warming may be an economically feasible practice. This hypothesis was evaluated in a soil warming experiment near Corvallis, Oregon. This experiment was prompted by the observation that multiple use of waste heat discharged in the condenser cooling water of thermal...

Effects of ACEs and Parenting Style on Children’s Cortisol Levels at Preschool

Creator:: DuBois, Carissa E.
Abstract:: Recently, the definition of adverse childhood experiences (ACEs) has evolved to also encompass environmental and contextual factors, termed expanded ACEs (Lipscomb et al., 2021). Given that responsive relationships in early childhood may dampen the response to traumatic stressors in the context of conventional ACEs (Flinn & England et al., 1997),...
