Published: April 2022

Abstract

Objectives
We examined the extent to which compassion practices helped guide skillful means of care among educators. We engaged educators in a collaborative design (co-design) process that foregrounded two components: (1) contemplative practice and (2) developing skill in how social interactions are embedded within wider systems through individual and joint inquiry. We analyzed the ways educators developed awareness of social suffering and set intentions to alleviate suffering. We examined how co-design fostered an understanding of compassion and new ideas about how to respond skillfully to suffering in schools.

Methods
Using qualitative methods, we analyzed data from educators who participated in co-design, including their written reflections, field notes, semi-structured interviews, and surveys.

Results
Educators identified multiple opportunities for acting with compassion, including approaching school-based interactions with compassion, cultivating compassion for themselves, and envisioning school change through a lens of compassion. Educators’ experiences in co-design directly informed how they imagined compassionate action in their schools. Specific elements highlighted were contemplative practice, reflection, and individual and joint inquiry.

Conclusions
The adaptation of a general program on compassion training can benefit from attending to how to show compassion in the context of concrete interactions in schools, and this can support educators in developing skillful means of care. Our analyses provide insight into the components that supported educators to offer compassion and suggest that educators’ skillful means of care can be cultivated through both contemplative practice and inquiry into social suffering. We offer a conceptual model for developing skillful means of care educational settings.

AbstractIn order to solve the problem of water resources shortage in the Western mining area of China and make it reasonably and effectively allocated, the optimal allocation model of water resources was established based on Water Evaluation and Planning System in this paper. This model simulated the water resources changes of 8 scenarios from 2015 to 2035. These scenarios are consisted of different economic growth, population changes, water saving and greening intensity. The optimal development scenario applicable to the mining area and the water resources allocation results corresponding to the scenario were determined by calculating the comprehensive benefits of society, economy and ecology. The results show that the optimal development scenario for the mining area is high-speed economic growth, powerful water saving and moderate greening. Under this scenario, the total water demand of the mining area will reach 39.73 million cubic meters by 2035, the demand shortage will be 1.7 million cubic meters, and the water shortage rate will be 4.28%. The water resources allocation result corresponding to this scenario can be used as a reference for decision makers, which can provide a scientific basis for the rational use of water resources in the Western mining area.

Published: April 2022

AbstractChronic kidney disorder may even be a significant health concern in Delta region particularly Dakahlia district, Egypt that’s characterized by permanent loss of kidney function through the years. Mercury considered as a silent threat to the environment and human life, through the world. This work purposes to access the effects of mercury overload in domestic water on the renal function. The study performed in spring 2019 on one hundred participants and conducted in two main areas that are getting ready to Lake Manzala. 100 ml of water, 40 ml of urine and 10 ml of blood samples from patients suffering from kidney diseases and healthy individuals as control group. These samples will be processed and analyzed to determine the incidence of active kidney disease. Mean levels of mercury in water, and urine samples of case group participants exceeded standard references and were significantly higher compared to control group (p = 0.0004 and 0.023 respectively) denoting more exposure to mercury. Proteinuria was significantly higher (p = 0.031) whereas, hemoglobin and hematocrit became significantly lower (p = 0.039 and 0.044 respectively) among case group participants which might be an indicator for kidney affection due to mercury exposure. Mercury overload in domestic water can cause renal impairment. The study showed that urinalysis for Proteinuria and hemoglobin values is commonly used as a screening test to detect kidney damage caused by mercury poisoning. Measures to prevent environmental pollutants and continuous monitoring of water sources in these districts are clearly necessary.

AbstractWater distribution networks require huge investment for construction. Involved people, especially researchers, are always seeking to find a way for decreasing costs and achieving an efficient design. One of the main factors of the network design is the selection of proper diameters based on costs and deficit of flow pressure and velocity in the network. The reduction in construction costs is accomplished by minimizing the diameter of network pipes which leads to the pressure drop in the network. Supplying proper pressure in nodes is one of the important design principles, and low pressure will not provide a complete water supply at the consumption site. Therefore, in this research, the problem of optimization in several sample networks was defined with the objectives of cost minimization and minimization of pressure deficit in the whole network. The EPANET software was used for hydraulic analysis of sample networks, and the multi-objective optimization process was performed by coding NSGA-II and MOPSO algorithms in the MATLAB software environment and linking them to EPANET. The cost function was initially defined only by considering the relationship between cost and diameter and the length of pipes, and in the next definition, the cost resulted by violation of the allowable pressure range was added to this function In both cases, the schedule for achieving the optimal answer was executed. The results showed that these algorithms have a high ability to find optimal solutions and are able to optimize the network in terms of cost and pressure by finding the appropriate pipe diameter. The time for reaching convergence was reduced by considering the cost of violation of the allowable pressure limits significantly and the optimal answer is obtained in a small number of repetitions. In NSGA-II and MOPSO algorithms in two-looped network with 20 and 30 iterations and run time of 0.66 and 0.8 s, respectively, and in Lansey network with 150 and 250 iterations and run time of 5.7 and 9.5 s, the optimal solutions were obtained.

Published: April 2022

AbstractLarge band gap and high electron–hole pair recombination rate limits practical application of TiO2 as a photocatalyst. Different methods are developed to remove or minimize the aforementioned limitations of TiO2. In this study, TiO2 nanoparticles were coupled with ZnO and CdO to address the above-mentioned limitations and hence to enhance the photocatalytic activity of TiO2. TiO2, ZnTiO2 and CdZnTiO2 nanocomposites were synthesized by simple co-precipitation method. The as-synthesized materials were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive X-ray (EDX), X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) and UV–visible spectrophotometry. Morphological analysis revealed that neat TiO2 is mostly agglomerated in spherical form. Their coupling with ZnO and CdO has increased the particle size. TEM analysis showed that CdZnTiO2 is highly crystalline having uniform mixing of CdO and ZnO particles with TiO2 in the ternary nanocomposite. The TEM images also showed that the sizes of the entire ternary CdZnTiO2 nanocomposites are mostly below 50 nm. XRD analysis confirmed the anatase TiO2, while the UV–visible analysis revealed the shifting toward higher wavelength. The band gap energy of TiO2 (2.65 eV) was decreased to 2.64 and 2.49 eV for ZnTiO2 and CdZnTiO2, respectively. The photodegradation results revealed that TiO2, ZnTiO2 and CdZnTiO2 degraded about 82, 90 and 94% methylene blue dye, respectively, within 120 min. Similarly, the CdZnTiO2 degraded 96% methyl orange dye within 100 min. It was observed that photodegradation of the dyes increases by increasing photocatalyst dosage and pH of the medium.

AbstractArsenic intoxication through contaminated water and food is a challenging problem worldwide. The objective of the present study was to isolate the As-resistant lactic acid bacteria (LAB) and assess the As sorption stoichiometry of LAB to validate its practical application as a bioremediation tool. The present study isolated 50 As-resistant LAB colonies from human (HS1-25) and albino mice (MM1-25) fecal samples. Out of 50 As-resistant LAB, the HS12 isolate exhibited the highest As removal efficiency (0.021 mg/h/g). The As bioremediation kinetic study determined the contact time 10 min and the pH between 5 and 7 for optimum As biosorption from the water. The Langmuir isotherm model (R2 = 0.993) was well fitted with the data than the Freundlich isotherm model (R2 = 0.876). The As bioaccumulation and scanning electron microscopy studies proved that binding of As onto cell membrane (0.000037 mg/g) and within the cell (0.000036 mg/g) are the mechanism of As sequestration of LAB HS12. The biosorption of As (2.28–20.37%) from fruit juice, soft drink and coffee as well as multimetals (0.025–0.179 mg/l; 16.22–98.69%) along with As (0.00024 mg/l) from water validated the practical application potential of HS12. The phylogenetic analysis of 16S rDNA amplicon (500 bp) of isolated potential HS12 LAB strains showed 97% similarity to Lactobacillus reuteri. Due to having As biosorption efficiency from water and liquid foods, it can be concluded that the human origin identified L. reuteri HS12 strain could be employed as a novel candidate of As bioremediation to safe environmental and human health.
Numerical assessment of Karun river influence on salinity intrusion in the Shatt Al-Arab river estuary, northwest of Arabian Gulf
Authors: Lafta Ali A. 
Published: April 2022

AbstractThe influence of Karun river inflow on salinity intrusion from the Arabian Gulf towards the upper reaches of the Shatt Al-Arab river estuary was evaluated by using Mike11, a one-dimensional numerical modeling technique. The simulations results indicated that, during the moderate and low flow conditions of the Shatt Al-Arab river, freshwater inflow from Karun river at 10 and 40 m3/s, respectively, could be capable of keeping salinity extent to not exceeded the confluence location of these two rivers. Additionally, the results indicated that in the case of a sharp decline of Karun river inflow, additional releasing of freshwater from the Tigris river can completely compensate for the Karun inflow. While in the case of cut off of Tigris river, the Karun inflow in the range of 60 m3/s could be able to keep salinity extent beyond the Abo Flous station during the simulation period. Furthermore, the possibility of discharging water with high levels of salinity from the farming projects located at the lower basin of Karun river towards the Shatt Al-Arab river estuary was taken into account. In such cases, the results suggested that during low and moderate flow conditions, freshwater inflow by about 250 and 225 m3/s, respectively, should be released from the Karun river to remains salinity extent below the Abo Flous location. A water management policy agreement between Iraq and Iran could be an effective solution to the salinity issue both in the Shatt Al-Arab river estuary as well as Karun river.
Parameters characterizing leakages from damaged water pipes in the aspect of environmental security
Authors: Iwanek Małgorzata 
Published: April 2022

AbstractLeakages from buried water pipes can result in suffosion posing a threat to the environment and the infrastructure existing in cities. Leakage of water from a pressure pipe into a soil susceptible to suffosion is a very complex phenomenon, characterized by a number of different parameters. Taking into account all parameters in the empirical tests of the buried water pipe leakage is practically impossible. Thus, it is necessary to select them so that on the one hand it is possible to perform a physical simulation of the phenomenon, and on the other to obtain reliable results of investigations. According to the Pareto principle, it can be stated that a small group of factors—about 20%—has a crucial impact on the phenomenon. Therefore, in empirical tests of water outflow from the underground water supply system, it is enough to consider 20% of the parameters affecting the analyzed phenomenon. The purpose of this work was to select these parameters. The selection was based on two types of research—literature research and computer simulations using the FEFLOW v. 5.3 software. The research allowed to select 4 out of 19 parameters which impact on the effects of the phenomenon of water outflow from pressure pipe to a soil susceptible to suffosion turned out to be the most essential: a pressure in the pipe, a leak area, a saturated conductivity coefficient of soil and an uniformity coefficient of soil.

AbstractThe Nickel oxide nanoparticles (NiO NPs) and Nickel oxide/Nanoclay nanocomposite (NiO/Nc NC) were synthesized by chemical reduction method and used for the photodegradation of Orange II dyes in aqueous solution. The synthesized samples were characterized through SEM, EDX, FTIR and TGA. The SEM analysis presented that the NiO NPs are spherical with irregular shapes and sizes. The size of particles is in the range of 100–400 nm. It was also observed that the NiO NPs are deposited on the surface of Nanoclay. The EDX study confirmed the formation of metal NPs and verify and purity. The FT-IR spectra of NiO and NiO/Nc NC presented peaks at 432 cm−1 and 504 cm−1, which correspond to NiO while peak at 1090–940 cm−1 is due to Si–O stretching vibration of orthosilicate anions and Si–O–Al groups. The photodegradation study illustrated that the NiO NPs and NiO/Nc NC degraded about 93 and 96% Orange II in aqueous medium, respectively within 20 min. The effect of various parameters like initial concentration of dyes, pH, recycled catalysts, and catalyst dosage were also studied.

Published: April 2022

AbstractThe synthesis of undoped barium oxide (BaO) and neodymium (Nd)-doped BaO nanoparticles (NPs) was carried out through the co-precipitation technique. The synthesis of cubic structure BaO NPs was confirmed through X-ray diffraction (XRD). The crystallite sizes calculated from X-rays diffractometric (XRD) results for undoped BaO and Nd-doped BaO were 10.50 nm and 10.04 nm, respectively. The morphological study and percent composition of synthesized NPs were investigated using a scanning electron microscope and energy-dispersive X-ray analysis. Thermogravimetric analysis confirmed the decomposition of precursor to BaO after annealing at ~ 500 °C. The band gap energy calculated for undoped BaO was 3.7 eV. The substitution of Nd to BaO decreased this value to 3.4 eV. The activation energy calculated for the doped BaO and undoped BaO was 16.5 kJ/mol and 22.5 kJ/mol, respectively. The Nd-doped BaO degraded about 96.4% dye, while the undoped BaO NPs degraded about 86.6% dye within 120 min. The synthesized BaO NPs were used as novel catalysts for the photodegradation of malachite green (MG) dye by varying irradiation time, catalyst dose, pH, temperatures and dye initial concentration. The maximum degradation efficiency was achieved at pH 4, catalyst dose 10 mg, dye initial concentration 50 ppm, and at a temperature of 50 °C. The dye degradation was also studied using the recovered catalysts.

Published: April 2022

AbstractGroundwater vulnerability assessment is critical for the effective groundwater management, particularly in areas with significant anthropogenic activities, such as agriculture. In this study, seven different methods, namely, DRASTIC, Pesticide DRASTIC, SINTACS, Nitrate SINTACS, GOD, AVI, and SI, were implemented using Geographical Information System techniques in Nea Moudania aquifer, Chalkidiki, Greece, to evaluate and identify groundwater vulnerability zones. The study area was classified into five categories: very low, low, moderate, high, and very high vulnerability. The southern and south-western parts of the study area had the highest pollution potential; the corresponding potential is lower in the northern part. Furthermore, single-parameter sensitivity analysis has revealed that the vadose zone and the topography were the most influential parameters of the vulnerability indexes, while the hydraulic conductivity exhibited the lowest effective weight. Finally, nitrate concentrations, taken from 23 observation wells, were employed for the validation of the aforementioned seven methods, using the coefficient of determination (R2). Results showed that Pesticide DRASTIC and Nitrate SINTACS were the most accurate and efficient methods for the present study area, which is characterized by intense agricultural activities.

AbstractDumpsite is a widespread land meant or designed for deposition of waste and unwanted materials from household, institutions, industries or the environment and is generally open or covered with soil layer with or without liner at the bottom. Dump/landfill is a major source of contamination of groundwater. This study is therefore designed to review studies on the impact of groundwater contamination due to dumpsites using geophysical and physiochemical methods. The geophysical methods adopted by the studies under review are Electrical Resistivity, Electromagnetic Induction using Very-Low-Frequency and Seismic Refraction methods. The results obtained using the resistivity methods showed zones or area with low resistivity as leachate plume and fractured subsurface as contaminant pathways. The result was complimented by other geophysical techniques applied. The results obtained with the application of physiochemical analyses of leachate inferred various degrees of severe contamination of groundwater due to organics, salts and heavy metals. As such, consumption of such water is dangerous to human health. The review also showed that age of the dumps and the migration distance of the leachate are important factors that require consideration because of the closer the dumpsite the higher the concentration of the contaminant.

Published: April 2022

AbstractFloods are the most common natural disasters on earth. Population growth with global warming and climate changes increases the impact of floods on people every year. Combating natural disasters such as floods is possible with effective disaster management. An effective disaster management can only be possible with a comprehensive risk analysis. Flood risks depend on many factors such as precipitation, flow, earth slope, soil structure, and population density. A holistic flood risk analysis considering all these factors will provide a more effective disaster management. This study focuses on an assessment of flood hazard analysis in Bitlis province of Turkey using analytical hierarchy method which is a multi-parameter modeling technique. Flood hazard zones were mapped according to the weight of the selected factor by using geographic information system. It is concluded that while especially the south-western regions are exposed to high flood risk due to high stream density and precipitation, the high slope and rugged nature of this region restrict the risk mainly to the vicinity of low elevation streams and high population regions.
