Abstract:
Despite the popularization of ozone technologies in agriculture, the theoretical aspects of the interaction of an ozone-air mixture with grain material remain under study. The simplified assumption that the change in the amount of ozone absorbed by the grain is proportional to the initial gas concentration does not accurately describe this process. Attempts to analytically determine a certain constant of the rate of ozone absorption by a unit of grain volume were also unsuccessful. The resulting expression was transcendental at that time. Its solution was possible only when performing repetiti

Abstract:
AbstractThis article examines the diffusion of technological innovation within the California wine industry by studying the adoption of ozone-cleaning technology. The paper compares ozone with other sanitizing systems and reviews current perspectives on innovation diffusion and adoption before describing and analyzing the results of a 2007 industry survey completed by 128 California wineries. We find that the decision to adopt ozone-cleaning technology was correlated with its economic advantages but not with either demographics of decision makers or variables indicative of a winery's ability t

Abstract:
Ozone is a prospective additive for enhancing and controlling combustion under lean or very lean conditions, and reduces NOx and particulate matter emissions simultaneously. Typically, in studying the effects of ozone on combustion pollutants, the focus is on the final yield of pollutants, while its detailed effects on the soot formation process remain unknown. Here, the formation and evolution profiles of soot containing morphology and nanostructures in ethylene inverse diffusion flames with different ozone concentration additions were experimentally studied.

Abstract:
The purpose of this paper is to investigate the protection of the ozone layer and the extensive effects of the hole diffusion on the life on Earth. First, the ozone layer is a layer in the atmosphere that absorbs ultraviolet radiation from the sun and protects life on earth from ultraviolet damage. UV radiation is destructive to living organisms and can cause health problems such as skin cancer, eye damage and even genetic mutations. Therefore, the existence and health of the ozone layer is directly related to the survival and health of organisms on Earth. Next, we will study the formation and

Containers were sealed and allowed to set for 15 min for O3 diffusion. Treated water was used to irrigate plants. Plants were in 10.2-cm pots and grown until floral initiation. Plants were harv

Abstract:
Exposure of murine L929 fibroblasts to ozone caused inactivation of the energy-coupled transport systems for 2-aminoisobutyric acid and Rb+. Ozone induced an increase of the apparent Km for 2-aminoisobutyric acid transport, with a constant Vmax, indicating impairment of the carrier function, rather than a decrease in the number of transport sites. The uptake rate of 2-deoxy-D-glucose, on the other hand, increased after exposure of the cells to ozone. This was caused by an increased Vmax. of facilitated diffusion, without increased after ozone exposure. Together with the K+ leakage described pr

Abstract:
By monitoring the electrical resistivity of single phase polycrystalline Y1Ba2Cu3O7-δ samples while changing their oxygen content in both ozone and ordinary oxygen environments, we were able to investigate the correlation between their average oxygen content and the diffusion time for oxygen inside the grains. We model the resistivity time dependence as a two-step process and find that this explains our experimental results satisfactorily. From this model we are able to estimate a value of the oxygen diffusion coefficient from our data that agrees well with other measurements. We also conclude

Stratosphere Troposphere exchange (STE) is important to study as it controls the chemical composition of the upper troposphere/lower stratosphere (UTLS) and thus the radiative balance of this region. STE also controls the transport of chemicals into the stratosphere which are vital to ozone depletion. The troposphere and the stratosphere have specific chemical characteristics and the transition region between these regions displays characteristics of both. Ozone and water vapour concentrations can be used as tracers for the characteristics of the troposphere and stratosphere. This thesis devel

A detailed investigation of the properties of cool flames, governed by LTC, is essential for the design of these new engines.
