Respiration parameter determination with non-obstructive methods

The Lipid Profile Parameter in Chronic Obstructive Pulmonary Disease Patients and Correlation with Severity of Disease

Introduction: More than 90% of the deaths caused by chronic obstructive pulmonary disease (COPD) occur in the low- and middle -income countries. The main aim of this study was to investigate the lipid profile levels in COPD patients and examine the correlation of total cholesterol, triglycerides, low-density lipoproteins, high density lipoproteins, and LDL/HDL risk ratio with COPD stages that a...

Sensitivity of truss plate model parameters to parameter determination methods

A factorial analysis was performed to assess the sen­ sitivity of Foschi’s nonlinear structural truss plate per­ formance parameters to parameter determination meth­ ods. The factors considered were treatment of asymmet­ ric failures of joints, the end of the data, and constraints placed on the asymptotic slope parameter M1. Results suggest that the parameter values are sensitive to the end of ...

The determination methods for non-ionic surfactants

A large number of non-ionic surfactants are discharged into water, which cause deterioration of water quality. Non-ionic surfactants have become an indicator of water quality monitoring. This article provides an overview of the classification of non-ionic surfactants, introduces the nature and hazards of fatty alcohol ethoxylates and alkyl phenol ethoxylates, and analyzes determination of non-i...

Cosmological-parameter determination with microwave background maps.

The angular power spectrum of the cosmic microwave background ~CMB! contains information on virtually all cosmological parameters of interest, including the geometry of the Universe (V), the baryon density, the Hubble constant (h), the cosmological constant (L), the number of light neutrinos, the ionization history, and the amplitudes and spectral indices of the primordial scalar and tensor per...
