laska has accepted two Stranded Gas Applications that will allow North Slope producers to enter into negotiations on terms to construct natural gas pipelines to the Lower 48. The applications, which suggest that the future for major pipelines to bring natural gas to the U.S. remains bright, also indicate the rising competitive interest in building such a pipeline. Alaska Gov. Frank Murkowski an...

I srael is very much an “island” in terms of electricity supply. For political reasons, its grid is not connected with those of its neighbors. Until recently, it had little in the way of domestic deposits of fossil fuels to generate electricity. Th us, Israel relies on imported coal as the primary fuel for base-load electric-power generation: In 2007, coal was used to generate about 70 percent ...

A multiobjective optimization model integrating with high-resolution geographical data was applied to examine the optimal switchgrass supply system in Tennessee that considers both feedstock cost and greenhouse gas (GHG) emissions in the system. Results suggest that the type of land converted into switchgrass production is crucial to both plant gate cost and GHG emissions of feedstock. In addit...

In this globalization era, petroleum companies are one of the dynamic supply chain entities, which require a dynamic process of capabilities. Companies may encounter problems related to the dynamic process in firm’s capabilities. Such dynamic process requires simultaneous acquisition and continuous re-evaluation of partners, technologies and organizational structures. However, the more flexible...

BACKGROUND In oxygen-enhanced lung MRI, difference maps of acquisitions during inhalation of room air and pure oxygen are calculated to assess lung function. The purpose of this study was to analyze how the calculation of these difference maps depends on the delayed signal change after switching the gas supply. METHODS Ten healthy volunteers were examined with an ECG and respiratory-triggered...

GRAMS T.E.E. & MATYSSEK R. 1999. Elevated CO2 counteracts the limitation by chronic ozone exposure on photosynthesis in Fagus sylvatica L.: Comparison between chlorophyll fluorescence and leaf gas exchange. Phyton (Horn, Austria) 39 (4): (31) (40). The interaction of elevated CO2 and enhanced chronic ozone (O3) impact was analysed throughout the growing season in the photosynthetic response (ch...

Upon ligation of the left branch of the pulmonary artery in the dog, there is exposed to the gases in the alveoli of this side a capillary bed supplied solely by systemic arterial blood. In such a lung, blood from the bronchial arteries has been demonstrated to gain direct access to the capillaries of the alveoli through large pre-capillary anastomoses that develop with branches of the pulmonar...

In this paper, we propose a multi-period mixed-integer linear programming model for optimal enterpriselevel planning of industrial gas operations. The objective is to minimize the total cost of production and distribution of liquid products by coordinating production decisions at multiple plants and distribution decisions at multiple depots. Production decisions include production modes and rat...

Rev. A Circuits from the LabTM circuits from Analog Devices have been designed and built by Analog Devices engineers. Standard engineering practices have been employed in the design and construction of each circuit, and their function and performance have been tested and verified in a lab environment at room temperature. However, you are solely responsible for testing the circuit and determinin...
