Firn air transport models are used to interpret measurements of the composition of air in firn and bubbles trapped in ice in order to reconstruct past atmospheric composition. The diffusivity profile in the firn is usually calibrated by comparing modelled and measured concentrations for tracers with known atmospheric history. However,...
OBJECTIVE – To determine the effect of 3 differing transfusion techniques on survival of autologous canine red blood cells (RBCs).
DESIGN – Prospective, blinded study.
SETTING – University Teaching Hospital.
ANIMALS – Nine healthy dogs.
INTERVENTIONS – Three distinct preparations of RBCs, each representing ~1% of red cell mass, were...
We assessed the effects of porosity and hydrophobicity on water uptake by biochars.
Biochars were produced from two feedstocks (hazelnut shells and Douglas fir chips) at
three production temperatures (370°C, 500°C, and 620°C). To distinguish the effects of
porosity from the effects of hydrophobicity, we compared uptake of water to...
Despite its very low oral bioavailability and rapid elimination, multiple reports of unexpectedly high bisphenol A (BPA) concentrations in the serum of pregnant mothers or cord blood have raised questions about BPA exposures during pregnancy. Thirty healthy pregnant women recruited to the study were evaluated for total BPA exposure over...
LiDAR (Light Detection And Ranging) is an emerging remote-sensing tool that can provide fine-scale data describing vertical complexity of vegetation relevant to species that are responsive to forest structure. We used LiDAR data to estimate occupancy probability for the federally threatened marbled murrelet (Brachyramphus marmoratus) in the Oregon Coast Range...
Pigeonpea [Cajanus cajan (L.) Millsp.] seed stored in triple layer Purdue Improved Cowpea Storage (PICS) bags for eight months retained germination and seed integrity significantly better than seed stored in traditional gunny bags. PICS bags prevented major damage caused by bruchids (Callosobruchus maculatus F.), while grain stored in gunny bags...
Brown marmorated stink bug, Halyomorpha halys (Stål), (Hemiptera: Pentatomidae) is
an invasive polyphagous agricultural and urban nuisance pest of Asian origin that is
becoming widespread in North America and Europe. Despite the economic importance
of pentatomid pests worldwide, their feeding behavior is poorly understood.
Electronically monitored insect feeding (EMIF) technology...
Lithothamnion rnuelleri is reported for the first time as one of the main components of rhodolith beds along the Eastern Pacific Ocean based on samples from Washington State (USA), Pacific Baja California (Mexico), southern Nicaragua, and Costa Rica. Individual rhodoliths ranged from fruticose to lumpy in morphology, and bi-sporangial, tetrasporangial,...
Tropical rainforests are significant contributors to the global cycles of energy, water and carbon. As a result, monitoring of the vegetation status over regions such as Amazônia has been a long standing interest of Earth scientists trying to determine the effect of climate change and anthropogenic disturbance on the tropical...
Three experiments compared ruminal, physiological, and performance responses of beef steers consuming hay ad libitum and receiving grain-based supplements without (control) or with (CAM) the inclusion of camelina meal. In Exp. 1, 9 steers fitted with ruminal cannulas received CAM (2.04 kg of DM/d; n = 5) or control (2.20...
