BACKGROUND It remains unknown whether desaturation profiles during daily living are associated with prognosis in patients with chronic obstructive pulmonary disease (COPD). Point measurements of resting oxygen saturation by pulse oximetry (SpO2) and partial pressure of arterial oxygen (PaO2) are not sufficient for assessment of desaturation during activities of daily living. A small number of s...

Let $G=(V,E)$ be a simple connected graph. A matching $M$ in a graph $G$ is a collection of edges of $G$ such that no two edges from $M$ share a vertex. A matching $M$ is maximal if it cannot be extended to a larger matching in $G$. The cardinality of any smallest maximal matching in $G$ is the saturation number of $G$ and is denoted by $s(G)$. In this paper we study the saturation numbe...

BACKGROUND Travel to mountain areas is popular. However, the effects of acute exposure to moderate altitude on the cardiovascular system and metabolism are largely unknown. OBJECTIVES To investigate the effects of acute exposure to moderate altitude on vascular function, metabolism and systemic inflammation. METHODS In 51 healthy male subjects with a mean (SD) age of 26.9 (9.3) years, oxyge...

BACKGROUND Different forms of chronic airway inflammation may involve diverse pathogenic elements. In general, deficient defence response is a feature of chronic obstructive pulmonary disease (COPD), whereas distorted immunoregulatory mechanisms lead to development of asthmatic symptoms. In addition to diverse effector mechanisms, the cellular and humoral elements participating in the developme...

Te-Ming Tu Shun-Chi Su Hsuen-Chyun Shyu Ping Sheng Huang Chung Cheng Institute of Technology Department of Electrical Engineering Taoyuan, Taiwan 33509 Republic of China Abstract. The intensity-hue-saturation (IHS) and Brovey transforms are two widespread image fusion methods in the remote sensing community. However, both are sensitive to the characteristics of the analyzed area. Restated, they...

The upscaled models of reservoirs result in coarse representation of flow for simulation gridblocks. This representation discards subgrid heterogeneities and flow complexities which can lead to an inaccurate performance prediction for reservoir processes. To tackle the problem, reconstruction techniques such as multiscale or upscaling–downscaling methods have been developed to recapture the sub...

PURPOSE Reports on intraocular pressure (IOP) changes at high altitudes have provided inconsistent and even conflicting RESULTS The purpose of this study was to investigate the effect of very high altitude and different ascent profiles on IOP in relation to simultaneously occurring ophthalmic and systemic changes in a prospective study. METHODS This prospective study involved 25 healthy mou...

the simulation of distillation columns is an essential step in design, optimization, and rating. in this paper, a new procedure has been proposed for the initial estimation of column profiles based on modified kremser’s group method for simple and/or complex columns. the effect of this initialization algorithm on simulation procedure has been studied through two examples. the results show signi...

this study was planned to investigate the effects of supplementation of cinnamon on fasting blood glucose levels and lipid profiles among type2 diabetic patients. 60 subjects with type 2 diabetes from both sexes (30 males and 30 females) were allocated to the intervention and control groups (30 individuals per group). t he doses of 1.5 g of cinnamon were equally administered orally in the form ...

In 2008 a stream flow created a sinkhole near Park City, Utah, creating an irregular-shaped depression in the alluvium about 22 m long, 10 m wide and 6 m deep. The entire discharge of a nearby creek flowed into the sinkhole increasing the size of the sinkhole. A total of 10 GPR and 4 seismic refraction profiles were conducted to find lateral and vertical extensions of this sinkhole. Interpretat...
