Okanagan University College was a public, post-secondary educational institution based in Kelowna, British Columbia, Canada. It evolved from Okanagan College , and the college's predecessor, the B.C. Vocational School 1963-1965. On 30 June 2005, OUC was split to create two new institutions, a new Okanagan College and UBC Okanagan. Wikipedia.

The purpose of this study was to examine the metabolic and hormonal responses to commercially available nutrition bars that differed in glycemic index and load. Three randomized conditions were matched for either carbohydrate content and/or caloric intake but differed in glycemic index and load. The results showed that a similar blood glucose concentration was achieved in each experimental trial despite differences in glycemic index or load. However, the nutrition bar with the lowest glycemic index and load resulted in the lowest insulin and highest glucagon concentration in serum during the postprandial period. Non-esterified fatty acids were lowest in the fasted state and with the moderate glycemic index and high load condition. Thus, for the same or lower amount of carbohydrate intake, the nutrition bar with the lowest glycemic index and load produced similar post prandial blood glucose responses to those of a higher glycemic index and load but this occurred as a result of significantly different gluco-regulatory and counter-regulatory hormone responses.

Accurate measurements of streamflow velocity and discharge can be challenging due to the technical nature of the instruments and often-associated high cost. Velocity-head rods measure the head difference in water flowing around an obstacle (i.e. the head rod) and use hydraulic theory to estimate water velocity. This article presents the construction and testing of a modified transparent velocity-head rod (mTVHR). Approximately 2400 pairs of mTVHR and SonTek FlowTracker (FT, acoustic Doppler) measurements were made on 31 dates, by seven operators at 14 sites. This data set allowed for the development of a calibrated relationship for velocity, for the investigation of accuracy among multiple users and for the definition of stream conditions where mTVHR use is appropriate. While there was evidence of differences between users for measurements of velocity-head and water depth, these differences were small and did not greatly influence discharge estimates derived using the instrument. While statistical analysis determined a minimum measureable velocity-head value of 1 mm, field experience with the instrument indicates the mTVHR should be used to measure velocity-head values greater than 2 mm. The maximum water depth recommended is approximately 0.75 m due to the 1-m height of the instrument and the difficulty of safe operation at moderately fast streamflow velocities. Turbulent streams and/or streams with large bed materials are not appropriate for use of the mTVHR due to rapid velocity-head fluctuations. The mTVHR is an accurate instrument for measuring streamflow velocity, depth and discharge. In addition, its ease of use, low cost (< CAN $100), and durability make it an attractive option for streamflow measurement. © 2016 Her Majesty in Right of Canada

Increasing land development throughout China poses serious risks to environmental services including water supplies, freshwater and terrestrial habitats, and soil erosion. Resource management must increasingly anticipate effects of resource use including the design of mitigation strategies. Because of the vast areas involved, detailed environmental assessments and resource management planning that require extensive data collection, analysis and modeling may not be suitable or cost effective in many instances. Yet, developing and communicating environmental information more broadly, in a spatial context, is necessary to support sustainable land uses and watershed management in China into the future. A 'digital watershed' provides a spatial framework, in which landforms and physical processes are analysed in context with patterns of resource use and human infrastructure. Analyses using digital watersheds can increase the site specificity and defensibility of resource planning at watershed to regional scales by government agencies and the private sector, while concurrently restraining costs of environmental assessments. The digital watershed represents a significant advancement over existing digital representations of land and streams in China. Here, we describe NetMap's digital watershed and analysis tools, illustrating their use in China.

It is known that use of a random measurement (sensing) matrix usually results in good recovery performance via orthogonal matching pursuit. This paper provides the probability of ensuring the recovery of sparse signals using orthogonal matching pursuit for the case where all entries of the measurement matrix are independently selected from a Gaussian distribution. The analysis relies on the mutual-coherence property of the sensing matrix. © 2015 IEEE.

The ability to understand phenomena in environmental systems is reliant on the ability to measure data about the system. In this realm, a high degree of non-homogeneity can exist between adjacent measurement points. The barrier to increased spatial sampling is device cost. Newer low-cost sampling platforms enable increased spatial sampling allowing for a better understanding of phenomena. Many sensing applications also require temporal synchronization across distributed devices to understand phenomena. This work presents a novel, low cost and flexible communications framework built on open source technologies with a sample application. It allows for multiple devices to be connected via a bus topology and controlled and addressed from a single master device. A time synchronization strategyis presented that allows for low cost devices to be used for temporally aligned sampling without the need for complex and expensive time synchronization equipment. The wired system is based on the proven and robust RS-485 physical layer, and addresses numerous issues that are often encountered with other technologies. The sample application of low range differential pressure measurements demonstrates the functionality of both hardware and software components. This paper describes the design and implementation of the communications framework that can be used to measure distributed sensors with low cost, temporal alignment of data.
