Quantifying effects of long-range transport of NO2 over Delhi using back trajectories and satellite data
(2024-01-19)Exposure to air pollution is a leading public health risk factor in India, especially over densely populated Delhi and the surrounding Indo-Gangetic Plain. During the post-monsoon seasons, the prevailing north-westerly ... -
Quantifying the association between habitual energy expenditure and blood pressure
(2000)Previous studies have demonstrated an association between physical inactivity and hypertension, but the methods used to assess activity have been subjective and imprecise. Recently methods have become available allowing ... -
Quantifying the imprint of a severe Hector thunderstorm during ACTIVE/SCOUT-O3 onto the water content in the upper troposphere/lower stratosphere
(2009)The development of a severe Hector thunderstorm that formed over the Tiwi Islands, north of Australia, during the Aerosol and Chemical Transport in Tropical Convection/Stratospheric-Climate Links with Emphasis on the Upper ... -
Quantifying the Risk to Health Care Workers of Cough as an Aerosol Generating Event in an Ambulance Setting: A Research Report
(2022-08-17)Introduction and Objective: United Kingdom Health Security Agency (UKHSA) guidance related to mask use for health care workers in a non-aerosol generating procedure (AGP) setting has remained as Level 2 water repellent ... -
Quantitative accuracy assessment of contextually filtered classified images
(2001)The use of post-classification contextual filters to increase the overall accuracy of classified remotely sensed imagery is a well known but under-used technique. Many practitioners have used a modal majority decision rule ... -
A Quantitative Analysis of Interfaces to Time-Triggered Communication Buses
(2021-04-28)Nodes connected to a time-triggered (TT) network can access the network interface in two different ways, synchronously or asynchronously, which greatly impacts communication timing and message lifespans (i.e., the time ... -
A Quantitative Analysis of TCP performance over Wireless Multihop Networks
(Institute of Electrical and Electronics Engineers (IEEE), 2001)An analytical model of a single TCP session based on a string topology in wireless multihop networks is presented. The model for the communication process also considers buffering, propagation delay and channel access ... -
A quantitative and qualitative analysis of factors affecting software process improvement
(2003)Despite the growing body of research on software process improvement (SPI), there is still a great deal of variability in the success of SPI programmes. In this paper, we explore 26 factors that potentially affect SPI. We ... -
Quantitative assessment of colorectal cancer tumor vascular parameters by using perfusion CT: influence of tumor region of interest
(2008)To prospectively determine whether position and size of tumor region of interest (ROI) influence estimates of colorectal cancer vascular parameters at computed tomography (CT). -
Quantitative Assessment of Damage in Composites by Implementing Acousto-Ultrasonics Technique
(2022-09-08)This study focused on quantitative damage severity assessment in composite materials using Acousto-Ultrasonics (AU), an in-service and active non-destructive inspection technique in which Lamb waves are communicated through ... -
Quantitative determination of single-bead metal content from a peptide combinatorial library
(2006-11-13)An electrothermal vaporizer inductively coupled plasma mass spectrometer (ETV-ICPMS) was used to quantitatively screen metals bound to single polystyrene (TentaGel) beads with immobilized oligopeptides. Tests were performed ... -
Quantitative helical dynamic contrast enhanced computed tomography assessment of the spatial variation in whole tumour blood volume with radiotherapy in lung cancer
(2010)We aim to assess the spatial distribution of blood volume (BV) in whole lung tumours in patients undergoing radiotherapy using helical dynamic contrast enhanced computed tomography (DCE-CT), and to determine whether ... -
Quantitative particle size, microtextural and outline shape analyses of glacigenic sediment reworked by paraglacial debris flows
(2009)Particle size analysis and scanning electron microscopy have been used with some success to differentiate sediments sampled from varying geomorphological environments. In the paraglacial environment, however, discrimination ... -
Quantitative PCR analysis of abundance of airborne propagules of Leptosphaeria species in air samples from different regions of Poland
(2012)When airborne propagules of Leptosphaeria maculans and L. biglobosa were collected in Poland at three ecologically different sites from 1 September to 30 November in 2004 to 2008, using a Hirst-type seven-day volumetric ... -
Quantitative resistance increases the durability of qualitative resistance to Leptosphaeria maculans in Brassica napus
(2010)It has frequently been hypothesized that quantitative resistance increases the durability of qualitative (R-gene mediated) resistance but supporting experimental evidence is rare. To test this hypothesis, near-isogenic ... -
Quantitative resistance to symptomless growth of Leptosphaeria maculans (phoma stem canker) in Brassica napus (oilseed rape)
(2009-04)Quantitative resistance to Leptosphaeria maculans in Brassica napus was investigated in field and controlled environments using cultivars Darmor (with quantitative resistance) and Eurol (without quantitative resistance). ... -
A quantitative structure-permeability relationship model for split-thickness skin absorption, reasoning for the choice of the database.
(2018-06-20)The skin is the largest organ in the human body, protecting the body from xenobiotic invasion (1). Local and systemic drugs may also be administered through the skin, therefore the need to measure the permeability of the ... -
Quantitative studies on dispersal of Pseudocercosporella herpotrichoides spores from infected wheat straw by simulated rain
(1983)Splash dispersal ofPseudocercosporella herpotrichoides spores from infected wheat straw was investigated using simulated rainfall (rate 13.8l h−1 m−2, volume mean diameter 2.9 mm) and wind (2 m sec−1) in a raintower/wind ... -
A quantitative technique for analysing robot-human interactions
