People infected with SARS-CoV-2 (COVID-19) can shed the virus in their feces, even if they do not have symptoms. The virus can then be detected in sewage, enabling wastewater surveillance to capture presence of COVID-19 in local communities. The goal of this study was to describe if constructed wetlands could remove the SARS-CoV-2 (COVID-19) genome copies particles (GCP) from discharging effluents of onsite septic tank systems in LaGrange County, Indiana. Effluents grab samples were collected at the inlet and outlet from one gravity horizontal flow (GHFCW), and one recirculating vertical flow constructed wetland (RVFCW) over a five-month period in 2021. Concentration of COVID-19 genomes copies particles was determined by reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR) based in two RNA (Ribonucleic acid) markers targeting the N1 and N2 nucleocapsid genes associated to the virus. The presence of markers N1 and N2 was detected in a greater concentration in the outlet of the septic tanks ahead of the inlet of both wetlands with results of 10³   to 10⁵ genome copies/L. The virus GCP exhibited low removal (≤ 10¹) for effluent passing through the RVFCW, where the GCP were generally removed to below detection limit in the GHFCW, indicating at least one, and reaching up to three log10 removal (10¹ to 10³⁾. Overall, the COVID-19 genomes copies particles showed much greater persistence to removal in the RVFCW versus the GHFCW treatment. Constructed wetlands can reduce but not eliminate the coronavirus from septic tank effluents.

This work was focused on the inhibition efficiency of three organic molecules (Benzoïc acid (BA), acid-3-chlorobenzoïc (A3CB) and acid-3 phenylthiobenzoïc (A3PTB)) for aluminium corrosion in 1M Hydrochloric acid. The obtained results show that the inhibition efficiency, IE (%) increases with increasing concentration of the three molecules, but it decreases with increasing temperature. The adsorption isotherm models have been used to describe the interactions of these molecules and the aluminium metal. We have examined all the possible interpretations we can deduce from the studied isotherm models. The Dubinin Radushkevich isotherm and that of Adejo-Ekwenchi have been used to identify the adsorption types. The thermodynamic adsorption functions have also been determined. Principal Component Analysis (PCA), which is a statistical method for reducing the number of the studied parameters had been used to select the pertinent sets which were used in Quantitative Structure Property Relationship (QSPR) non-linear models. The contribution of each parameter in the chosen sets were also determined

The high spoilage rate of fresh food is a common problem in large commercial supermarkets in China. Fresh food can be affected at all stages of the supply chain, including production, transportation, storage and distribution. Acid Electrolyte Water (AEW) is a pollution-free and harmless green preservation technology. According to the fresh food preservation requirements of large supermarkets, based on electrolytic water technology, AEW strong oxidizing solution generator is combined with spray mechanism and rapid cooling mechanism, and a fresh food antibacterial and anticorrosive treatment device based on AEW strong oxidizing solution is designed.

The damage of corn kernels during harvesting, processing, storage, and transportation is not only related to the magnitude of the load they are subjected to, but also to the number of load applications. The number of load applications can affect the energy absorbed by corn kernels. Multiple compression tests were conducted on corn kernels with different moisture contents under 200N loading and unloading, and it was found that as the moisture content decreased, the number of cycles required for corn kernel crushing increased; Studying the hysteresis energy consumption characteristics of corn kernels, it was found that the area of the hysteresis curve of corn kernels gradually decreases; Through experimental research on the energy absorption of corn kernels during crushing, it was found that corn kernels with different moisture contents absorb different amounts of energy. The lower the moisture content, the higher the energy absorbed before corn crushing.

In the current context of sustainable development, it is vitally important that the concerns of local people are taken into account in the planning of all urban development and management of urban green spaces. Unfortunately, most of the time, local people are not involved in the implementation of urban forest management policies. This study, carried out in the town of Daloa, has highlighted the perceptions and expectations of local people in terms of the development of urban green spaces. To do this, surveys were carried out among people in all the districts of the town. The surveys revealed that all social strata of the population attach great importance to vegetation in their environment (74% to 100%). The most common use is for ornamental purposes (25%), while the highest proportion (31% to 83%) use green spaces 1 to 20 times a month. The function of urban forests most appreciated by the population is the ecological function, but the major constraint justifying the absence of green spaces in homes is land pressure (50% to 70.21%). All this information gathered from the public must be taken into account for future urban development programmes and, above all, for the sustainability of urban green spaces.
