Abstract
Underground coal extraction at Coal Mine Velenje occasionally gives rise to odour complaints from local residents.
This manuscript describes a robust quantification of odorous emissions of mine sources and a model-based analysis aimed to establish a better understanding of the sources, concentrations, dispersion, and possible control of odorous compounds during coal extraction process.
Major odour sources during underground mining are released volatile sulphur compounds from coal seam, that have characteristic malodours at extremely low concentrations at µg/m3 levels. Analysis of 1028 gas samples taken over a six-year period (2008-2013) reveal that dimethyl sulphide ((CH3)2S) is the major odour active compound present in the mine, being detected on 679 occasions throughout the mine. While hydrogen sulphide (H2S) and sulphur dioxide (SO2) were detected 5 and 26 times.
Analysis of gas samples has shown that main DMS sources in the mine are coal extraction locations at longwall faces and development headings and that DMS is releasing during transport from main coal transport system.
The dispersion simulations of odour sources in the mine have shown that the concentrations of DMS at median levels can represents relatively modest odour nuisance. While at peak levels the concentration of DMS remained sufficiently high to create an odour problem both in the mine and on the surface. Overall, dispersion simulations have shown that ventilation regulation on its own is not sufficient as an odour abatement measure.

Abstract
The global surface temperature is predicted to increase by 1.0°C to 5.7°C by the end of the twenty-first century from the Inter-governmental Panel on Climate Change (IPCC) report, but the effects of higher temperatures on soil properties and heavy metal accumulation in plants are unclear. To investigate the effects of soil temperature on soil geochemical properties and the accumulation of heavy metals in plants, we grew rapeseeds (Brassica napus) in pots filled with contaminated field soil at four different temperatures (22.5, 22.9, 23.7, and 24.6°C) in a controlled growth chamber. The concentration of heavy metals in the rapeseed samples at different temperatures showed a positive partial correlation coefficient with the soil temperatures. The order of partial correlation coefficients was Zn (0.50) > Cd (0.21) > Cu (0.19) > As (0.15) > Pb (0.13). However, only the Zn concentration in rapeseed showed a significant moderate positive correlation (r = 0.50, p < 0.01) with soil temperature. In terms of soil properties, soil pH positively correlated (r = 0.49, p < 0.01), whereas the cation exchange capacity (CEC) negatively correlated (r = -0.55, p < 0.001) with soil temperatures. These results suggest that increasing soil temperatures affect the plant metabolisms and soil geochemical properties and enhance the soil-to-plant transfer of heavy metals. Therefore, future global warming may lead to unforeseen losses in crop productivity and pollutant accumulation, consequently resulting in detrimental effects on the health of animals and human beings.

Abstract

Purpose Crop sensitivity to root zone salinity can vary over time during a cropping season, which can lead to severe damage when high sensitivity coincides with high soil salinity. The variation in salinity sensitivity of sunflower (Helianthus annuus L.) during its growth cycle is not known.
Methods Two pot experiments were conducted in sand culture with a complete nutrient solution to test the response of sunflower to salinity at different growth stages. Solutions were repeatedly flushed through pots in excess to maintain the specified salt concentrations in the soil solution. In Experiment 1, salt-sensitive growth stages were determined by applying solutions of increasing electrical conductivity (EC < 0.7, 2, 4 or 8 dS m-1) throughout vegetative, flowering or grain filling stages based on well-defined phenology. In Experiment 2, the most sensitive stage to root-zone salinity was determined by exposing the plants to 10-day periods of salinity (EC < 0.7, 8, 16 and 24 dS m-1) overlapping by 4 days starting from the 13-leaf to grain filling.
Results In both experiments, decreases in seed yield were associated with exposure of plants to elevated EC during the period when the disk flower was opening to ~95% anthesis, while grain filling was the least sensitive. In experiment 2, measurements of ion concentrations and rates of photosynthesis in leaves suggested that Na+ toxicity decreased yield due to decreases in the availability of photosynthates to flowers.
Conclusion To maximise sunflower yield in saline soils, crop management should minimise salinity stress from flower opening to anthesis.

Abstract
Background

While otorhinolaryngology (ORL) surgery is common in children, hospitalization, surgery, and post-discharge home management are stressful experiences for young patients and their family caregivers. Findings from literature highlight a lack of time in hospitals to support ORL surgery children and their caregivers in the perioperative process, along with the risks of caregivers’ autonomous web or social media resources investigation. Therefore, this study aims to evaluate the effectiveness of a mobile health application with contents to support ORL patients and their caregivers in the perioperative period to reduce caregivers’ anxiety and children distress compared to standard care.

Methods

An open two arm randomized control trial study design will be adopted. The intervention will consist of a mobile health application with contents to support ORL patients and their caregivers in the perioperative period. One hundred and eighty participants will be enrolled and randomly assigned to the experimental group that will have in use the m-health application or the control group. The control group will receive standard information and education about the ORL perioperative period by healthcare providers orally or through booklets. The primary outcome will be the difference between intervention and control group in preoperative caregiver state anxiety. Secondary outcome measures include children’s distress before surgery and family preparation for hospitalization.

Discussion

The results of the study will be critical for the implementation of a new and safe model for the management of care and education in paediatrics. In this model, organisational and health-related positive outcomes may be achieved by supporting continuity of care and empowering citizens for informed participation and satisfaction in paediatric health promotion and management.

Abstract
Silver (Ag)-decorated titanium dioxide (TiO2) catalysts were produced under ultrasound irradiation at different loadings of Ag nanoparticles (from 5 to 50 wt%). Then, the catalysts were supported on internal and external surfaces of alumina hollow fibers with asymmetric pore size distribution. The produced catalysts were considered for Cr(VI) photoreductions. The ultrasound-assisted process potentialized the distribution of Ag nanoparticles on the TiO2 surface. The loading of Ag nanoparticles at concentrations greater than 5 wt% was necessary to improve the TiO2 activity for Cr(VI) photoreduction. The loading of Ag nanoparticles at 30 wt% improved the Cr(VI) photoreduction of the single TiO2 catalyst from 40.49 ± 0.98 to 55.00 ± 0.83% after 180 min of reaction. Suspended and supported Ag-decorated TiO2 catalysts achieved total Cr(VI) photoreduction after 21 h of reaction. The adjusted reaction rate constant with the externally supported Ag-TiO2 catalyst was 3.57x10-3 ± 0.18 x10-3 min-1. Similar reaction rate constants were achieved with suspended and internally supported catalysts (approximately 2.70x10-3 min-1). After 10 sequential reuses, all catalysts presented similar Cr(VI) photoreductions of approximately 66%. Nevertheless, the use of the externally supported catalyst is suggested for Cr(VI) photoreductions due to its superior catalyst activity at least in the first reuse cycles.

Published: January 2023

Abstract
Though the biological treatment employing bacterial strains has wide application in effluent treatment plant, it has got several limitations. Researches hence while looking for alternative biological organisms that can be used for secondary treatment came up with the idea of using microalgae. Since then, a large number of microalgal/cyanobacterial strains have been identified that can efficiently remove pollutants from wastewater. Some researchers also found out that the algal biomass not only acts as a carbon sink by taking up carbon dioxide from the atmosphere and giving oxygen but also is a renewable source of several value-added products that can be extracted from it for the commercial use. In this work, the cleaning effect of different species of microalgae/cyanobacteria on wastewater from varied sources along with the value-added products obtained from the algal biomass as observed by researchers during the past few years are reviewed. While a number of review works in the field of phycoremediation technology was reported in literature, a comprehensive study on phycoremediation of wastewater from different industries and household individually is limited. In the present review work, the efficiency of diverse microalgal/cyanobacterial strains in treatment of wide range of industrial effluents along with municipal wastewater having multi-pollutants has been critically reviewed.

Published: January 2023

Abstract
Vehicle routing problem with time windows (VRPTW), which is a typical NP-hard combinatorial optimization problem, plays an important role in modern logistics and transportation systems. Although the particle swarm optimization (PSO) algorithm exhibits very promising performance on continuous problems, how to adapt PSO to efficiently deal with VRPTW is still challenging work. In this paper, we propose a neighborhood comprehensive learning particle swarm optimization (N-CLPSO) to solve VRPTW. To improve the exploitation capability of N-CLPSO, we introduce a new remove-reinsert neighborhood search mechanism. We calculate an information matrix (IM) recording the probability of adjacency between two clients based on the information about the clients themselves and the local information about the elite individuals to guide the removal operation of the neighborhood search. At the same time, we combine the cost matrix (CM) that records the cost of customer removal with IM to create a guided reinsertion operator based on local information to guide the routing. Moreover, to enhance the exploration of N-CLPSO, a semi-random disturbance strategy is proposed. To
prevent degradation of the population, the longest common sequences of elites are saved when performing the disturbance. To illustrate the effectiveness of N-CLPSO, this paper conducts extensive experiments

Published: January 2023

Abstract
This study aims to study the effect of different combinations of Laser or/and Rhizobium on the growth parameters of clover plants. To carry out this study, irradiation of seeds by laser radiation and seeds incubation by Rhizobium combination with laser exposure times 5, 10, and 15 minutes compared to untreated seeds were used. Growth plants were cut four times during the growing season every 40–45 days, then growth parameters were measured. Obtained results showed that using treated seeds by combination laser exposed for 5 minutes and Rhizobium gave higher growth parameters followed by 10 minutes and control. While the exposure time of 15 minutes was less value. By using Laser excised times or/and Rhizobium, the results indicated that the growth parameters values of cover plants at irrigated with fresh water were higher than clover plants irrigated with groundwater. So, the authors recommended to use of irridiation by Laser beam and/or incubation by Rhizobium of clover seeds or any different seeds crops in order to improve vegetation and productivity of crops.

Abstract
Vehicle emission is a major source of atmospheric secondary organic aerosols (SOA). Driving condition is a critical influencing factor for vehicular SOA production, but few studies have revealed SOA production dependence on the rapidly-changing real-world driving conditions. Here, a fast-response oxidation flow reactor system is developed and deployed to quantify the SOA formation potential under transient driving conditions. Results show that the SOA potential varies by orders of magnitude, e.g., 20-1500 mg kg-fuel-1 and 12–155 mg kg-fuel-1 for China V and China VI vehicles, respectively. High speed, acceleration, and deceleration are found to considerably promote SOA production due to higher organic gaseous emissions caused by unburned fuel emission or incomplete combustion. In addition, China VI vehicles significantly reduce SOA potential, yield, and acceleration and deceleration peaks. Our study provides experimental insight into vehicular SOA formation under transient driving conditions, which would benefit high-time-resolved SOA simulations in the urban atmosphere.
WITHDRAWN: Bifurcation scenarios in the hardware-in-the-loop experiments of highly interrupted milling processes
Authors: Toth Rudolf R. , Stepan Gabor 
Published: January 2023

Abstract
Hardware-in-the-loop (HIL) measurements of highly interrupted milling processes were conducted. A real spindle was used with a dummy tool on which the cutting forces were emulated with contactless sensors and actuators. During the experiments, Hopf- and period-doubling bifurcations were identified. The nonlinear dynamics of these period-doubling bifurcations are analyzed for a discrete model of highly-interrupted milling. This investigation found the bifurcation to be subcritical, which draws the attention to the limited practical validity of linear stability analysis.

Abstract
This research investigates the ease with which people in India can access natural disaster videos on YouTube with the goal of raising awareness and empowering the general populace to take action for their own safety. The article describes the most common category of calamity for which videos were produced in India. The comments added by viewers in each video's comment area are analyzed in order to determine the viewers' intentions and feelings in relation to the available videos. This is done so in order to analyze viewers' sentiments. For this reason, study makes use of Webometric analyzer to retrieve the pertinent information from YouTube by utilizing the YouTube API key. Furthermore, the R-studio environment was utilized in order to do the sentiment analysis. After the raw data have been collected, they go through a process of manual verification so that the legitimacy and accuracy of the data may be confirmed. Following the application of the criteria for elimination, there were a total of 467 relevant movies and 20689 comments that were retrieved for further examination. Following a comprehensive investigation, it was discovered that the majority of films were published between the years of 2008 and 2010. When looking at the total amount of videos released on the topic of natural disasters in India, the most notable channels are INDIA TODAY, WION, and NDTV, among others. These channels have the most footage available online. Using the keyword analysis that was performed on the videos' titles, it was discovered that the majority of the movies in the collection were about cyclones, rather than any of the other kinds of natural disasters that can be found in India.

Abstract
Type 1 conventional dendritic cells (cDC1s) are the most efficient cross-presenting cells that induce protective cytotoxic T cell response. However, the regulation of their homeostasis and function is incompletely understood. Here we observed a selective reduction of splenic cDC1s in mice with Zeb1 deficiency in dendritic cells, due to excessive cell death, rendering mice higher resistance to Listeria infection. Moreover, cDC1s from other sources of Zeb1-deficient mice displayed impaired cross-presentation of exogenous antigens, resulting in compromised antitumor CD8+ T cell responses. Mechanistically, Zeb1 facilitated the production of phagosomal reactive oxygen species by repressing the expression of microRNA-96 that targeted Cybb mRNA of NADPH oxidase Nox2. Consequently, loss of Zeb1 in cDC1s diminished phagosomal membrane rupture that permits antigen export to the cytosol. Cybb re-expression in Zeb1-deficient cDC1s fully restored the defective cross-presentation while microRNA-96 overexpression in Zeb1-sufficient cDC1s inhibited cross-presentation. Therefore, our results identify a novel Zeb1-microRNA-96-Cybb pathway that controls cross-presentation in cDC1s and uncover an essential role of Zeb1in cDC1 homeostasis.
Changes in self-harm and suicide in California from 2017-2021: a population-based study

Published: January 2023

AbstractBackground: Self-harm and suicide are major public health problems with immediate and long-term effects on individuals, families, and communities. In 2020 and 2021, stressors wrought by the COVID-19 pandemic, stay-at-home mandates, economic turmoil, social unrest, and growing inequality likely modified risk for self-harm. The coinciding surge in firearm purchasing may have increased risk for firearm suicide. In this study, we examined changes in counts and rates of fatal and nonfatal intentional self-harm in California across sociodemographic groups during the first two years of the COVID-19 pandemic relative to prior years.Methods:We used California-wide death data and University of California (UC)-wide hospital data to summarize fatal and nonfatal instances of intentional self-harm across race/ethnicity, age, education, gender, region, and method of harm. We compared case counts and rates in 2020 and 2021 with 2017-2019 averages.Results: Suicide decreased overall in 2020 (4123 deaths; 10.5 per 100,000) and 2021 (4104; 10.4 per 100,000), compared to pre-pandemic (4484; 11.4 per 100,000). The decrease in counts was driven largely by males, white, and middle-aged Californians. Conversely, Black Californians and young people (age 10-19) experienced increased burden and rates of suicide. Firearm suicide also decreased following the onset of the pandemic, but relatively less than overall suicide; as a result, the proportion of suicides that involved a firearm increased (from 36.1% pre-pandemic to 37.6% in 2020 and 38.1% in 2021). Females, people aged 20-29, and Black Californians had the largest increase in the likelihood of using a firearm in suicide following the onset of the pandemic. Counts and rates of nonfatal, intentional self-harm in UC hospitals increased in 2020 (2160; 30.7 per 100,000) and 2021 (2175; 30.9 per 100,000) compared to pre-pandemic (2083; 29.6 per 100,000), especially among young people (age 10-19), females, and Hispanic Californians.Conclusions: The COVID-19 pandemic and co-occurring stressors coincided with heterogeneous changes in risk of self-harm and suicide across the California population. Marginalized racial groups, females, and younger people experienced increased risk for self-harm, particularly involving a firearm. Public health intervention and policy action are necessary to prevent fatal and nonfatal self-harm injuries and reduce related inequities.
