Climate change could alter the distribution of mountain pine beetle outbreaks in western Canada
Download2012-01-01
Sambaraju, Kishan R., Carroll, Allan L., Zhu, Jun, Stahl, Kerstin, Moore, R. Dan, Aukema, Brian H.
Climate change can markedly impact biology, population ecology, and spatial patterns of eruptive insects due to the direct influence of temperature on insect development and population success. The mountain pine beetle Dendroctonus ponderosae (Coleoptera: Curculionidae), is a landscape-altering...

Spittlehouse, D.L., Hamann, A., Murdock, T.Q., Wang, T.
This study addresses the need to provide comprehensive historical climate data and climate change projections at a scale suitable for, and readily accessible to, researchers and resource managers. This database for western North America (WNA) includes over 20 000 surfaces of monthly, seasonal,...

Climbing simulated vegetation to heights of ungulate hosts by larvae of Dermacentor albipictus (Acari: Ixodidae)
Download2000
Samuel, W. M., Shostak, A. W., McPherson, M.
Abstract: Larvae of winter ticks, Dermacentor albipictus (Packard), ascend vegetation in autumn and form clumps that attach to passing ungulate hosts. We tested the hypothesis that vegetation height determines the height of clumps. During the vegetation-to-ungulate transmission period (early...

Clinical and research applications of real-time ultrasonography in bovine reproduction: A review
Download1994
Ambrose, Divakar J., Burton, Bruce, Rajamahendran, Rajadurai
Transrectal real-time ultrasonography has proved to be a rapid and reliable technique for studying reproductive functions in cattle. Through ultrasonography it is now established that follicular growth occurs in wave-like patterns during each estrous cycle. It has been shown that follicular...

Yu, H., Jomha, N. M., Elliott, J. A., Al-Abbasi, K. K., McGann, L. E.
In previous research, we successfully cryopreserved intact human articular cartilage on its bone base with high chondrocyte viability using a vitrification protocol that entailed sequential exposure to several cryopreserving agents (CPAs) at lowering temperatures resulting in a high final...

Clinical variability in arch wires: A preliminary study evaluating mechanical and surface characteristics of two different sized rectangular stainless steel wires
Download2007
Vena, Alessandro, Carey, Jason, Badawi, Hisham
Experimental characterization of arch wires has been performed in many previous studies; however with the advent of new arch wire materials being introduced, some new experimental methods and characterization are required. Since literature is available for comparison, this paper examines...

Pfeffer, B. A., Chader, G. J., Zakeri, Z. F., Wu, S. P., Bernstein, S. L., Wong, P., Chambers, M. L.
Purpose: The clusterin gene encodes a multi-functional protein that has been identified in different tissues, including a number of different eye tissues, primarily in the mouse and to a much lesser extent in humans. Clusterin has been implicated in a number of cellular processes such as lipid...

We propose a simple microfluidic droplet generator for controlling the droplet size over a wide range. A planar co-flow device was developed with controllable c- phase channel width using a deformable wall structure. The design was benefited from the increased shear force due to the channel...
