greenhouse gas emissions are considered as the main cause of climate change. investigation of economic dimensions of greenhouse gas emissions and its environmental effects especially in a situation where the volume of greenhouse gas increasingly is rising is very important. in this paper, the relationship between greenhouse gas emissions i.e. carbon dioxide and gdp per capita and energy consump...

this article aims to identify what and how factors influence management of supply risk in automotive industry supply chain. based on grounded theory and 13qualitative in-depth interviews with 10 managers in iran's automotive industry supply chain, a theoretical framework is developed to examine antecedents and effective factors of this process. this framework suggests a broad range of fact...

impact of supply chain drivers on supply chain performance has no far been studied. in this research we want identifying supply chain drivers, classifying them and examining their relationship with iran's supply chain performance. this research has innovation in identifying and classifying drivers and examining relationship between drivers and supply chain performance we used bsc for assessing ...

BACKGROUND The hemodynamic balloon model describes the change in coupling from underlying neural activity to observed blood oxygen level dependent (BOLD) response. It plays an increasing important role in brain research using magnetic resonance imaging (MRI) techniques. However, changes in the BOLD signal are sensitive to the resting blood volume fraction (i.e., [Formula: see text]) associated ...

Background: MRI microvasculature imaging is a powerful tool for characterizing hemodynamic properties in vivo. Different approaches have been proposed for measuring vascular properties such as cerebral blood volume fraction (CBV), vessel size index (VSI), vessel density as well as vessel architecture, though all have used analytical expressions for modeling the imprint of the vasculature on the...

Groundwater is an important, but undervalued, national resource in Scotland. Groundwater is present both in the bedrock, where much of the flow is through fractures, and in the superficial deposits, where intergranular flow dominates. The most productive bedrock aquifers are the Permian sandstones and breccia in SW Scotland and the Devonian sandstones in Fife, Strathmore and Morayshire. Alluviu...

BACKGROUND Three different techniques to evaluate endothelium-dependent vasodilation in the peripheral circulation have been described but not simultaneously tested in a large-scale population-based setting. This study aimed to evaluate the feasibility and usefulness of these techniques in the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS) study. METHODS AND RESULTS I...

The objective of this study is to present the test results of variable air volume (VAV) air conditioning system optimized by two objective genetic algorithm (GA). The objective functions are energy savings and thermal comfort. The optimal set points for fuzzy logic controller (FLC) are the supply air temperature (Ts), the supply duct static pressure (Ps), the chilled water temperature (Tw), and...

the performance of a supply chain can be evaluated in either a cross-sectional or a time series manner, and data envelopment analysis is a useful method for both types of evaluation. in this paper we develop an index and indicator of productivity change that can be used with radial and non-radial models for supply chain malmquist index. the supply chain malmquist productivity index (scmpi) can ...
