Solidification behavior and environmental risk assessment of toxic elements on tailings from carbothermic reduction-magnetic separation of lead blast furnace slag
Authors: Jiang Z.-W. , Li M.-T. , Wei C. , Cao Y.-L. , Li X.-B. , Deng Z.-G.
Published: December 2023

Lead blast furnace slag (LBFS) generated during lead smelting is a hazardous solid waste containing potentially toxic elements (Pb, Zn, As, and Cd) with high mobility and solubility. In this study, a process for the utilization of LBFS by carbothermic reduction-magnetic separation method is proposed. Leaching toxicity and Tessier sequential extraction experiments were conducted on LBFS and magnetic separation tailings (TS), and the environmental risk was evaluated using the risk assessment coding index and potential ecological risk index. The obtained results showed that the potentially toxic elements in the TS were solidified in the spinel phase or silicate phase. In addition, the XRD, SEM-EDS, and FTIR results showed the formation of PbCa2Si3O9, ZnAl2O4, and Ca3(AsO4)2 phases. The leaching concentrations of Pb, Zn, As, and Cd in TS were much lower than the toxicity characteristic leaching procedure (TCLP) and China standard leaching test (CSLT) limits. The results of Tessier sequential extraction procedure confirmed that the proportions of the stable residual state of the potentially toxic elements in TS were significantly higher than in LBFS. Furthermore, the ecological environmental risk level for the TS decreased significantly compared to that of LBFS.

Published: December 2023

The first experimental results of the indoor air quality in two kindergartens located in the Republic of Srpska are presented in this paper. Kindergarten representatives for the year of construction (old and new), building materials, and energy efficiency have been chosen. Indoor air quality measurements (air temperature, relative humidity, ventilation rate, CO2, and radon concentration) were performed during the winter of 2015/2016. Measured indoor air quality parameters are discussed and compared to the international standards BAS EN 16798-1, ASHRAE 62.1, and ISO 7730. The average measured radon concentrations for both buildings have not exceeded the level of 200 Bq/m3, but for reliable results, long-term measurement needs to be performed. The CO2 concentration in the old kindergarten fulfills the BAS EN 16798-1 requirement for Category I during 62.43% of total occupancy time, while for the new kindergarten, it is only 5.79% of full occupancy time. Results of CO2 concentration confirm that good sealing of the envelope of new buildings and user behavior (number of users and natural ventilation) does affect air quality. Furthermore, a high correlation between CO2 concentration and relative humidity in both buildings and a more considerable correlation for the new building have been observed.

Authors: Er-Raki Mohammed , Hasnaoui Safae , Hasnaoui Mohammed , Amatoul Fatima , Bourich Mohamed
Published: December 2023

Experimental results obtained using a photovoltaic thermal hybrid solar
system are presented and discussed. This hybrid combination is an emerging
technology that combines photovoltaic panels and solar thermal collectors in
one bi-functional component providing both electrical and thermal energy.
The main objective of this coupling is to improve the efficiency of the
photovoltaic panels by reducing their operating temperatures and recovering
the thermal energy they dissipate, using heat transfer fluids (water in the
present study). A theoretical analysis of photovoltaic, thermal and
photovoltaic thermal hybrid solar systems is presented. Both electrical and
thermal performances of the proposed photovoltaic thermal prototype system
are evaluated and analyzed under local weather conditions of
Essaouira-Morocco (Latitude: 31.51,| Longitude: -9.76). A comparative study
in terms of overall energy efficiency of photovoltaic thermal and
conventional photovoltaic systems is conducted and discussed. The obtained
experimental findings show that, unlike the conventional photovoltaic panel
for which the overall efficiency does not exceed 8.22%, the hybrid system
makes it possible to achieve a maximum overall efficiency of about 42.72%.
The extracted energy?s quality and efficiency are evaluated through the
exergy analysis of the proposed photovoltaic thermal system. The electrical
and thermal exergy efficiencies recorded for the studied sytem are 9.78% and
3.07%, respectively.
Online monitoring of the burning characteristics of single pulverized coal particle in O2/N2 and O2/CO2 environments
Authors: Abdul Gani , Wall Terry , Moghtaderi Behdad
Published: December 2023

The objective of this study is to compare the ignition and burning characteristics such as burnout times of volatiles and char, and ignition mechanism of single pul?verized coal particle burning in air (O2/N2) and oxy (O2/CO2) environments. An entrained flow reactor with photo detector has been employed for this study. This technique involves online monitoring of radiation emission from an individual coal particle. Individual particles of sub-bituminous or lignite coal particle with size in the ranges of 106-125 micron and 180-212 micron particles have been injected into an air (O2/N2) or oxy (O2/CO2) environment inside an entrained flow reactor. The oxygen concentration in the ambient gas is varied between 10%-50% by volume. The volatile and char burnout times have been obtained from time histories estimated from the radiation emitted by the particle. The results show an obvious increase in the burning rates of volatiles and char with increasing oxygen concentration. Further, when compared to N2 atmosphere, the burning rate and radiation intensity are found to be lower in CO2 atmosphere, especially at lower oxygen concentrations. An indication of the possible ignition mechanism has been outlined from the percentages of single and double peaks observed in the radiation emission histories. The complete experimental investigation shows that the burning rates of both volatiles and char are predominantly affected by the oxygen concentration, particle size and gas temperature. The theoretical results from a single particle model has been used to validate the trends and the combustion durations obtained from the present experimental study and is published as a separate manuscript.

Authors: Lei Shilin , Duan Yulong , Long Jun , Xiang Kaijun , Liu Liwen , Li Zehuan , Wen Ziyang , Zheng Lulu
Published: December 2023

The factor of combustion and explosion remains one of the main constraints on coal mining and management. To clarify the impact of structural properties on the consequences of gas explosion disasters during coal mining, this article conducts a study on the impact of the elastic modulus of structures on gas explosion disasters. The research results indicate that in the case where structures with high elastic modulus must exist, the elastic modulus of the structure has minimal impact on the structure during the early stage of flame development. The area of flame front and the degree of deflagration also decrease with the increase of elastic modulus, but the disturbance degree of air-flow and flame in the pipe increases with the increase of elastic modulus. The peak flame velocity at elastic modulus of 0.7 GPa and 2.8 GPa increased by 3.56% and 7.47% compared to elastic modulus of 0.18 GPa, respectively. The upstream overpressure peak increased by 24.63% and 42.52%. The downstream overpressure peak increased by 11.19% and 20.62%. The peak values of flame velocity and overpressure increase with the increase of elastic modulus, while the explosion intensity and pressure rise rate increase with the increase of elastic modulus. The explosion intensity index at elastic modulus 2.8 GPa is approximately 1.45 times that at elastic modulus 0.18 GPa. Therefore, it is necessary to choose structures with smaller elastic modulus as much as possible to achieve the best fire and explosion suppression effect.
The Effect of Water Coolant and Bur Type on Pulp Temperature When Removing Tooth Structure and Restorative Dental Materials
Authors: Mafrici C , Kingston M , Grice R , Abbott PV
Published: December 2023

Objective

The aim was to compare intrapulp temperature (IPT) changes when flat-fissure diamond burs and pear-shaped tungsten carbide burs were used to cut tooth structure, amalgam, and composite resin with and without water coolant.

Methods

Thermocouples were inserted into the pulp chamber of extracted intact mandibular molars. The thermocouples were connected to an electronic thermometer that detects temperature every second to an accuracy of 0.1°C. IPT changes were recorded while using a high-speed handpiece during MOD cavity preparations (n=40), composite resin removal (n=40), and amalgam removal (n=40). A two-way ANOVA was used for each procedure to test for the effect of bur (pear-shaped tungsten carbide vs flat-fissured diamond) and water coolant (on vs off), with significant main effects (α=0.05) further analyzed using Tukey's multiple comparison test.

Results

During MOD cavity preparation, water coolant reduced changes in IPT (0.03±0.27°C) compared to no water coolant (1.27±0.29°C) when tungsten carbide burs were used (p<0.05) but not when diamond burs were used. During composite resin removal, tungsten carbide burs had less changes in IPT (0.55±0.18°C) compared to diamond burs (1.66±0.50°C) with no water coolant (p<0.05). Water coolant also reduced changes in IPT (0.09±0.14°C) compared to no water coolant (1.66±0.50°C) when diamond burs were used (p<0.01). Water coolant did not significantly affect IPT when tungsten carbide burs were used. During amalgam removal, tungsten carbide burs had lower changes in IPT (0.56±0.15°C) compared to diamond burs (1.88±0.43°C) with no water coolant (p<0.05). Water coolant also significantly reduced changes in IPT (0.71±0.2°C) compared to no water coolant (1.88±0.43°C) when diamond burs were used (p<0.05) but not when tungsten carbide burs were used.

Conclusions

Water coolant reduced IPT changes when drilling tooth structure with tungsten carbide burs, but not when removing amalgam or composite. Conversely, water coolant reduced IPT changes when drilling with flat fissure diamond burs to remove amalgam and composite, but not when removing tooth structure. When amalgam and composite were removed without water coolant, the tungsten carbide burs resulted in lower IPT changes than when flat fissure diamond burs were used in the same way.

Authors: Jurado CA , Lee D , Ramirez P , Cortes-Treviño DA , Tsujimoto A
Published: December 2023

Objective

The aim of this investigation was to compare the fracture resistance of chairside computer-aided design and computer-aided manufacturing (CAD/CAM) lithium disilicate–reinforced ceramic occlusal veneers with and without margin and traditional full coverage premolar crowns.

Methods and Materials

A total of 60 chairside CAD/CAM lithium disilicate–reinforced ceramic (Amber Mill, Hass Bio) restorations were designed and fabricated with a chairside CAD/CAM system (CEREC Dentsply Sirona). The restorations were divided into three groups (n=20): 1) occlusal veneer with 1.0-mm uniform occlusal thickness and with chamfer margin; 2) occlusal veneer with 1.0-mm uniform occlusal thickness and without margin; and 3) full coverage crown with uniform occlusal thickness and gingival margin. Occlusal veneers and crowns were cemented with dual cured resin luting cement (Multilink, Ivoclar Vivadent) to printed resin dies, load cycled (5 million load cycles at 1 Hz with 275 N force), and then loaded until fracture. Load at break (LB) and peak load (PL) until fracture were recorded. Scanning electron microscope images of the tested restorations on the abutments were obtained.

Results

Fracture strengths were different depending on the design of the restoration. There was no significant difference in fracture strength between the two types of occlusal veneer (LB: 1132.45 N; PL: 1143.30 N for veneers with margin; LB: 1149.25 N; PL: 1219.05 N for veneers without margin). Full coverage crowns showed the lowest fracture resistance (LB: 936.26 N, PL: 976.42 N), which was significantly lower than both designs of occlusal veneer.

Conclusions

The fracture resistance of the CAD/CAM lithium disilicate–reinforced ceramic restorations was influenced by the design. Occlusal veneers with and without margin displayed higher fracture resistance than traditional crowns.

Published: December 2023

Health literacy is the ability to obtain, read, understand, and use healthcare information to make appropriate health decisions and follow instructions for treatment. With the onset of Covid-19 disease, the public needs to have access to new and accurate information. The present study investigated the Coronavirus-related health literacy in Covid-19 patients referred to a teaching hospital in a developing country and its relationship with demographic variables.
Method: This survey research is a descriptive-analytical type. The research instrument includes LS-COVID-Q22). Patients with Covid-19 were referred to the hospital from December 5, 2020 to July 5, 2021.The samples were selected using a sample size determination formula of 190 people. Statistical analysis was performed with SPSS software version 26.
Results: The overall average score of health literacy related to coronavirus in patients with Covid-19 at Imam Reza teaching hospital in is 84.31 which is the desired level. Among the dimensions of health literacy, the highest score belonged to “Understanding health information” and the lowest score belonged to “Evaluate health information”. “Age” as a demographic factor, is the only factor that has been associated with health literacy related to the coronavirus.
Conclusion: Although the level of Coronavirus-related health literacy is favorable in this study, the participants in this study were mostly patients who were able to answer the research questions, were not hospitalized, had a sufficient level of literacy to understand the questionnaire questions, and most of them were medical staff who were familiar with the components of health literacy. However, considering that health literacy training related to coronavirus has an effective role in disease prevention and control, therefore, creating and promoting the necessary platform for teaching the components of health literacy , especially  for elders is recommended by trustees and policymakers. Lack of proper evaluation of information sources leads to improper health practice.

Published: December 2023

In the era of online business, the use of photos owned by others has become a common practice, often overlooked as a serious matter. However, such actions can give rise to serious issues, particularly considering the significant economic value associated with creativity in business endeavors, especially with regard to photo rights. This research aims to investigate the phenomenon of using photos in commercial activities and analyze the perspectives of copyright law and Islamic law on this phenomenon. Through a qualitative approach in literature research, the research objectives, encountered issues, methods employed, and findings obtained will be detailed. The results of the study indicate an increasing trend in the use of photos for commercial purposes, driven by the perspective of some online business practitioners who perceive the claiming of others' photo rights as commonplace. Islamic law permits the use of photos in trade as long as they are one's own creation and obtained in accordance with Islamic principles. On the other hand, copyright law prohibits the use of photos in commercial activities due to infringement of copyright. Thus, this research provides a profound understanding of the impact of this phenomenon and a comparison between the perspectives of Islamic law and copyright law regarding the use of photos in online business transactions.

How household healthcare expenditures redistribute disposable income? An analysis using Bangladesh household income and expenditure survey, 2010.
Authors: Molla Azaher , Chi Chunhuei
Published: December 2023

Essential healthcare is a civil right. Payments toward healthcare is a moral compulsion, and no less strong than legal compulsion like income tax. Healthcare payments can redistribute disposable income. Redistribution may be vertical (from rich to poor or opposite) and horizontal (from men to women or from households without children to households with children). Health planners are interested in degrees to which redistribution occurs. In this paper, we aim to analyze how well different forms of healthcare payments in Bangladesh redistribute disposable income. Our data comes from Bangladesh Household Income and Expenditure Survey, 2010. Using the methods developed by Aronson et al. (1994), we assessed average rate effect, progressivity, horizontal equity and re-ranking. The results suggest that Bangladesh health systems finance has a pro-rich redistribution of disposable income. Post-payment disposable income decreases for the poor and increases for the rich. As a result, the poor are in a shortfall in disposable income, which ultimately get them to impoverishment, and or push them to deeper poverty. On the contrary, the rich become richer due to increase in post-payment disposable income. This leads to an increase in inequality.

Published: December 2023

OBJECTIVE

To measure the trunk vertical displacement (VD) in horses trotting on a water treadmill (WT) at different water depths (WDs) and speeds.

ANIMALS

6 sound Standardbred horses (median age 12 years [IQR:10.5-12]).

METHODS

The horses were trotted on a WT at 2 speeds (3.5 m/s and 5 m/s) and during 4 conditions: dry treadmill (DT), WD at mid-cannon (WD-CAN), mid-radius (WD-RAD), and shoulder (WD-SHOUL). The dorsoventral movement was obtained with accelerometers placed over the withers, thoracolumbar junction (T18), tuber sacrale (TS), and sacrum (S5). The VD was defined with the median value of the upward (Up) and downward (Down) amplitudes of the vertical excursion during each stride. The difference of VD at each sensor location was compared between the DT and the 3 WDs, and between the 2 trotting speeds for the same condition.

RESULTS

The VD amplitudes were significantly increased at any sensor location when trotting in water at WD-CAN and WD-RAD compared to DT (P < .05 for all), with the highest increase at WD-RAD and T18. When the speed increased from 3.5 to 5 m/s, the VD amplitudes were significantly decreased at T18 at each water level (P = .03), and at WD-RAD only for the withers and TS (P = .03).

CLINICAL RELEVANCE

Both water depth and speed affect the trunk VD in horses at trot on a WT with an opposite effect. The VD increases when increasing the WD up to mid-radius, while the VD decreases when increasing the trotting speed, with the main effects observed at the thoracolumbar junction.
Power-Supply Geopolitics. The Dependence of European Economies on Imports of Fuels from Russia
Authors: Czerny Mirosława
Published: December 2023

International relations (including those revolving around economic cooperation between states, or the economic dependence of one state on another) actually entail the development of a concept of power and its efficacy, interlinkage, and a systemic configuration. Geography’s input is, then, to place these issues within the space of economic activity and life, linking these to an analysis of resources. Geography also provides for the construction of models for the spatial relations between different actors. In turn, analysis from a geopolitical point of view, inter alia, involves itself in the study of dependency and power through reference to relations which entail domination, the exerting of influence, independence or mutual dependence, territorial integrity, development, political and social stability, and security (Dallanegra Pedraza 2010). Then there are the issues concerning the use of natural resources, as these affect relations between states, thus representing research topics for geography. Through the analysis of the interactions between variables which recall the aforesaid relations, it has here proved possible to construct models describing, or helping to account for, present-day world relations, characterised by dependence on fossil fuels (as raw materials supplying energy) which originate in Russia. This process makes use of available statistical data and reports, including ENERDATA 2021 and Key World Energy Statistics 2021, from the US Energy Information Administration (EIA).
Compassion in three perspectives: Associations with depression and suicidal ideation in a clinical adolescent sample
Authors: Jonsson Emmy , Dennhag Inga
Published: December 2023

Background

Adolescence is a critical period for mental development where the consequences of psychopathologies can be exceedingly harmful, and compassion has been identified as a protective factor for adolescents’ mental well-being.

Aim

The aim of this study was to explore three perspectives of compassion – Self-compassion, Compassion for others, and Compassion from others – and their relationship with depression and suicidal ideation in adolescents.

Method

This Swedish cross-sectional study included 259 psychiatric patients (ages 16–22). Participants completed a survey including the self-assessment scales “Reynolds Adolescent Depression Scale – Second Edition” (RADS-2), “Suicidal Ideation Questionnaire – Junior Version” (SIQ-JR), and “Compassion Engagement and Action Scale – Youth” (CEAS-Y). Linear regression analyses were used to determine whether participants’ levels of compassion predicted depression and suicidal ideation.

Results

Self-compassion and Compassion from others significantly predicted both depression and suicidal ideation. Girls, on average, reported higher levels of depressive symptoms and suicidal ideation and lower levels of self-compassion compared to boys. The correlation between compassion and depressive symptoms, however, appeared to be stronger in boys. There was also a positive correlation between Compassion for others and suicidal ideation.

Conclusions

The results suggest that Self-compassion and Compassion from others may have a significant protective effect against depression and suicidal ideation, especially in boys. However, due to the relatively small sample of boys (n = 40), further research is needed before any solid conclusion can be drawn regarding possible gender differences. Additionally, the combination of low Self-compassion and higher levels of Compassion for others may be associated with suicidal ideation.

Authors: Ventavoli Daniela Maria Andrade , Rezende Dalilla Carvalho , De Moraes Clauciana Schmidt Bueno , Jubrail Mariana de Paula
Published: December 2023

Theoretical benchmark: Coffee farming has a productive chain of economic, cultural, historical and social relevance for Brazil. Assisted pollination carried out by bees becomes an alternative in increasing productivity and coffee quality, in addition to contributing to biodiversity. In this context, this work was developed with the objective of analyzing the benefits of pollination by bees in coffee production, verifying the effects on quality by comparing physicochemical parameters of the grains.
 
Method: Coffee samples were collected from two areas from pollinated and non-pollinated coffee trees, grouped together forming a sample for each treatment and subsequently dried in a suspended terrace until reaching 12% humidity. For physicochemical characterization of the grains, analyzes of Soluble solids, thousand grains mass, Titratable acidity, pH, Electrical conductivity, and Coloring were performed.
 
Results and conclusion: In the pollinated area, the values of Soluble solids were higher with 31.49°Brix in raw grains and 23.20°Brix in cherry grains and in the Mass of a thousand grains with 113.35g in the raw grain. In the electrical conductivity, titratable acidity and pH parameters, lower values were observed in the pollinated area in the raw grains. For Coloring, better results were observed in coordinates L: 30.98; a: 0.44; b:11.39 in coffee from an area of assisted pollination. The obtained results were significant in pollinated area in the parameters Soluble solids in raw beans and cherry and in Mass of a thousand beans and Color (coordinate L) only in raw beans, when compared to non-pollinated coffee.
