Abstract:

Two classes of dispersion models are currently used for (regulatory) odour dispersion, namely Gauss and Lagrange models. These models generally predict time-averaged concentrations, often over one hour. Therefore, the models have to be adopted somehow to cope with short-term odour peaks which can be smelled by the human nose. Over the last years, the authors have developed an approach where the shortterm peaks are parameterized according to atmospheric stability (“peak-to-mean” factors). This approach is used with the Austrian Odour Dispersion Model AO

Abstract. The peak-to-mean concept developed earlier by the authors to calculate odour-related separation distances is applied here to meteorological input for dispersion models provided by ultrasonic anemometers. In addition to conventional meteorological input parameters like wind direction, wind speed and stability classes, three-dimensional sonics provide also turbulence information via the Obukhov stability parameter and the variance of the wind speed, which can be used directly to determine peak-to-mean ratios depending on the distance from the source.

Abstract:

In this paper, two approaches to estimate odour concentrations in dispersion models are compared. The approaches differ in the estimation of the momentary (peak) odour concentration for the time interval of a single human breath (approximately 5 s). The Austrian Odour Dispersion Model (AODM) is a Gaussian model with peak-to-mean factors depending on wind speed and atmospheric stability. The German Lagrange code AUSTAL2000 uses a constant factor 4 in all meteorological conditions to derive the maximum odour concentration over a short integration time. As the Lagrange model, in contrast to the G

Abstract:

Odour in the atmosphere is usually characterized by an intermittent time series of high peaks and periods of low (or zero) concentrations. The peak-to-mean ratio (PMR) is commonly used to estimate short-term peaks from long-term averages to assess the odour impact. The objective of this study was to quantify the peak-to-mean ratio of odour intensity (PMR_OI) in the atmosphere near swine operations. Fifteen human assessors (sniffers) were trained to use an 8 point odour intensity scale to measure odour intensity in the ambient air near two swine operations. In each measurement session, the snif

Abstract:

Purpose:To compare EMG activity of selected hip and knee muscle groups in female athletes performing a modified single-leg squat and the 2-leg squat using the same relative intensity.Methods:Eleven Division I female athletes from a variety of sports (soccer, softball, and track) completed the study. EMG measurements were taken as the subjects completed 3 parallel repetitions at 85% of their 3-repetition maximum on each exercise. Mean and mean peak EMG data from the gluteus medius, hamstrings, and quadriceps and the quadriceps:hamstrings EMG ratio were compared between the 2 exercises.Results:S

Abstract:

OBJECTIVE: To investigate the growth hormone (GH) response to glucagon stimulation test (GST) in a population of healthy men over 50 years old in comparison to insulin tolerance test (ITT), analysis of the spontaneous 24-hour GH profile and insulin-like growth factor 1 (IGF-I). METHODS: 27 healthy men aged between 51 and 65 years were tested. RESULTS: Using non-parametric correlation analysis, a positive correlation between GH peak after GST and mean IGF-I (r = 0.528; p = 0.005) was found, as well with GH peak in 24-hour profile (r = 0.494; p = 0.009). No correlation was found comparing GH pea

Abstract:

Purpose:To determine the reliability of the Dynamic Strength Index (DSI) in college athletes.Method:Nineteen male college athletes performed the squat jump (SJ) and isometric midthigh pull (IMTP) to determine peak force, on 2 separate days. Reliability was assessed by intraclass correlation coefficient (ICC), typical error (TE), percentage change in the mean, smallest worthwhile change (SWC), and coefficient of variation (%CV).Results:Peak force for the SJ was 2137 ± 499 N and 2781 ± 435 N for the IMTP, resulting in a mean DSI of 0.78 ± 0.19. Peak forces in the SJ (ICC = .99, TE = 57.22 N, cha

Abstract:

Principal component analysis (PCA) is essential for diminishing the number ofdimensions across various fields, preserving data integrity while simplifyingcomplexity. Eigenfaces, a notable application of PCA, illustrates the method'seffectiveness in facial recognition. This paper introduces a novel PCAapproximation technique based on maximizing distance and compares it withthe traditional eigenfaces approach. We employ several image quality metricsincluding Euclidean distance, mean absolute error (MAE), peak signal-to-noiseratio (PSNR), signal-to-noise ratio (SNR), and structural similarity ind

Abstract:

Introduction Peak expiratory flow measurement is a simple measure of respiratory capacity to diagnose airflow obstruction and monitor treatment response in patients with pulmonary diseases. But there is wide diurnal variability in its values. The objectives of this study was to determine the diurnal variability of peak expiratory flow rate in healthy adults. MethodsThis cross-sectional study was done in employees of Kathmandu Medical College, Duwakot between March to August 2020. A total of 74 subjects of 30-45 years were included in the study. After adequate training, subjects were aske
