Sewage sludge management is known to cause odour impact over the environment. However, an information gap exists about odour emissions quantification from different treatment strategies. In the present work, odorous emissions generated in a full-scale sewage sludge composting plant were characte...

Odor monitoring plays a crucial role in implementing suitable odor mitigation strategies at composting plants. Odor activity value (OAV) analysis is an instrumental-based approach that could simplify and reduce costs of odor monitoring by dynamic olfactometry; yet, the relationship between both ...

In recent years, there has been a growing concern about potential impacts on public health and wellbeing due to exposure to environmental odour. Separation distances between odour-emitting sources and residential areas can be calculated using dispersion models, as a means of protecting the neigh...

Livestock odor properties have not been well understood and the role of hedonic tone (HT) in establishing appropriate odor impact criteria has not been investigated. Five odor properties, including odor concentration (OC), intensity (OI), HT, persistence, and character descriptor, were studied f...

For determining setback distances considering multiple air pollutants, a comprehensive study was conducted to simulate the atmospheric dispersion of odour, ammonia (NH3), hydrogen sulfide (H2S), and respirable dust using an US EPA air dispersion model AERMOD for a commercial dairy, broiler, and ...

Odour is a significant challenge for regulators of waste handling facilities due to the increasing demand for land surrounding these facilities. Many sites, including landfills, composters, abattoirs and rendering plants, that were once isolated are now close to residential areas. In some cases,...

Chemesthesis, along with taste and olfaction, is a primary component of flavor that engages the trigeminal system through specific chemical binding. For instance, many gums or confectionaries incorporate chemical cooling agents, such as Wilkinson Sword (WS) compounds, to create the sensation of ...

This study focused on evaluating the use of powdered activated carbon (PAC) adsorption for the treatability of various odor compounds with different structures. The adsorption performance of 14 odor compounds under various PAC dosages were fitted with two isotherm models (the Langmuir and Freund...

People exhibit different sensitivity to the signaling properties of body odors in the social context. Here, we aimed to investigate whether visual status modulates sensitivity to socially-relevant cues carried by body odors and whether it affects psychophysical ratings of such smells. We compare...

The improvement of color similarity between stereo images can bring better performance to stereo matching algorithms. For this purpose, we present a color correction method to alleviate the color discrepancy between a pair of stereo images, so that the color appearance of one image, i.e., the ta...

The color memory effect is the non-abelian gauge theory analog of the gravitational memory effect, in which the passage of color radiation induces a net relative SU(3) color rotation of a pair of nearby quarks. It is proposed that this effect can be measured in the Regge limit of deeply inelasti...

A graph is ambiguously k-colorable if its vertex set admits two distinct partitions each into at most k anticliques. We give a full characterization of the maximal ambiguously k-colorable graphs in terms of k×k-matrices. As an application, we calculate the maximum number of edges an ambiguously...

Since there is a wide range of applications requiring image color difference (CD) assessment (e.g. color quantization, color mapping), a number of CD measures for images have been proposed. However, the performance evaluation of such measures often suffers from the following major flaws: (1) tes...

We propose color polarization multiplexing metalenses composed by two sets of cross nanoholes etched on the silver film. Cross nanoholes are arranged on the concentric rings and they are optimized to be equivalent to half wave plates for two different wavelengths. This design can ensure the effe...

The present paper proposes an improved colour-modelled CH* and C2* measurement using a digital colour camera. A complete measurement description has been given. As an important part of the method, the camera sensor spectral response has been obtained through the optical calibration process. With...

In the dual-lens system with monochrome and color cameras, the gray image captured by the monochrome camera has better quality than the color image from the color camera, but does not have color information. To get high-quality color images, it is desired to colorize the gray image with the colo...

The indicator-based polymeric color standards for color referencing in digital color analysis (DCA) of optical chemical sensors (optodes) are proposed. In the novel standards, the colors referring to the actual absorption bands of the protonated and deprotonated forms of the indicator are mixed ...

Motivated by investigations of rainbow matchings in edge colored graphs, we introduce the notion of color-line graphs that generalizes the classical concept of line graphs in a natural way. Let H be a (properly) edge colored graph. The (proper) color-line graph CL(H) of H has edges of H as verti...

This study aims to explore the relationships between Instagram user characteristics and color features of their photos. Based on the assumption that individuals who are similar in characteristics would exhibit a similar style in their social media photos, this study pays attention to color as on...

The molecular geometry, vibrational frequencies, gauge-including atomic orbital (GIAO) 1H and 13C chemical shift values of 4-cyanobenzaldehyde isonicotinoyl-hydrazone monohydrate in the ground state have been calculated by using the Hartree–Fock (HF) and density functional method (DFT/B3LYP) wi...
