Authors: DEMİRHAN Esma , ATAR Sevgi , ER Günay , OKUTAN İpek , KURU Ömer
Published: September 2022

Objectives: Fatigue and pain symptoms were common complaints among post-COVID-19 patients, and these lead to impaired quality of life (QoL). We aimed to evaluate severity of pain and fatigue 3 months after disease onset in discharged COVID-19 patients.
Methods: Patients were contacted by phone at their third month following disease onset. Demographic data of the patients such as weight, height, body mass index (BMI), gender, smoking history, comorbidities, length of hospitalization, duration of stay in the intensive care unit, were recorded. The patients' pain and fatigue severities were evaluated by visual analog scale (VAS). QoL was questioned with the EuroQol Group Association five-domain, three-level questionnaire (EQ-5D-3L).
Results: A total of 392 participants enrolled into the study. At admission, 94.6% of the participants had fatigue and 73.7% of them had pain. A high proportion of them still reported fatigue (55.1%) and pain (41.3%) at third month. The mean value of pain-VAS score was 5.37 ± 3.85, and it was 7.58 ± 2.82 for fatigue-VAS at admission. VAS scores of pain and fatigue at third month were 1.44 ± 2.11 and 2.04 ± 2.40 respectively. While 66.6% of the patients reported moderate-severe pain at disease onset, the rate was 18.1% at the third month. And also almost half had severe pain at admission (48%), it was 2.8% at third month. At disease onset 89.6% of the patients reported moderate-severe fatigue (severe: 48%). Aproximately one third of them had moderate-severe fatigue (27.9%) at third month (severe: 5.1%). The mean value of EQ-VAS score was 26.76 ± 20.26 at admission, and it was 78.84 ±16.15 at third month. Statistically significant differences were recorded between the disease onset and third month in terms of pain-VAS fatigue-VAS, and EQ-VAS scores (p < 0.001). Female gender, ICU admission, long duration of hospitalization, older age, higher BMI scores, multiple comorbidities, fatigue and pain severity were related to the decrease in QoL scores.
Conclusions: Hospitalized COVID-19 survivors need ongoing support for pain, fatigue complaints and impaired QoL after discharge. The factors that cause poor QoL should be taken into account during post-COVID-19 follow up.
Londyn wobec ochrony mniejszości żydowskich w Europie Środkowo-Wschodniej (1918–1919)
Authors: Jeziorny Dariusz
Published: September 2022

Autor monografii przedstawia rolę dyplomacji brytyjskiej w ustanowieniu traktatowej ochrony Żydów w krajach Europy Środkowo-Wschodniej po zakończeniu I wojny światowej. Analizuje kwestię przygotowań Rządu Jego Królewskiej Mości do negocjacji pokojowych i pokazuje, jakie znaczenie miała w nich problematyka żydowska. Omawia wpływ zajść antysemickich, o których szeroko rozpisywała się ówczesna prasa, na podejmowane kroki. Uwydatnia rolę Brytyjczyków w procesie decyzyjnym Konferencji Pokojowej w Paryżu w sprawie gwarancji dla mniejszości i ich kształtu. Dochodzi do wniosku, że to właśnie dyplomacji brytyjskiej zawdzięcza Europa uchwaloną w Paryżu pierwszą w historii wersję międzynarodowego zapewnienia praw mniejszościom. Wskazuje wreszcie na wpływ działań podmiotów zewnętrznych na linię polityczną Londynu (inne mocarstwa, kraje Europy Środkowo-Wschodniej, organizacje żydowskie). Wszystkie te kwestie pozwalają na określenie profesjonalizmu i skuteczności dyplomacji brytyjskiej po zakończeniu I wojny światowej.

Due to distinct agro-climatic, geological and edaphic characters in hilly region of Uttarakhand owing the large genetic diversity of crop species, vegetation and indigenously developed land races. Due to less water and other external inputs requirement traditional legume crops are well suited to rainfed condition of hilly region of Uttarakhand. These traditional legume crops are rich in taste, odour, colour, nutritional values, medicinal and soil fertility enhancement characteristics. But due to increased population pressure, changed food habit, lack of innovative agricultural technology, environment conservation policies and increased market forces a shift from traditional to modern intensive agriculture system during the past few decades resulted in decline in area and production of traditional legume crops. For increasing the area and production (61.18 thousand ha and 53.63 thousand ton) of traditional legume crops, a suitable long-term strategies and management practices for strengthening the distribution facilities for produce and availability of market for conservation of traditional legume crops needs to be worked out in the state.

Authors: Birla Jinendra , Patel B.M.
Published: September 2022

Background: Cowpea [Vigna unguiculata (L.) Walp] is most widely grown pulse-cum-vegetable crop. It plays an important role in maintaining soil fertility. Besides, nitrogen which is fixed in the soil from the atmosphere by the crop specific Rhizobium found in root nodules of this crop, phosphorus is another important element which inter-alia enhances the nitrogen fixation capability of the crop. In addition to biologically fixed nitrogen, crop also requires nitrogen through fertilization to meet its initial requirement (Mishra and Baboo, 1999).
Methods: A field experiment was on conducted during kharif season of the year 2015 at Agronomy Instructional Farm, C.P. College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar Gujarat. The experiment was laid out in randomized block design with four replications and 10 treatments comprising of integration of different organic sources.
Result: Our investigation in the significant improvement in N content in seed and N uptake by cowpea were noted with the application of 50% N through FYM + 50% N through vermicompost + PSB (T8), whereas, higher N content in stover and P content in seed were recorded under treatment T9 (50% N through castor cake + 50% N through vermicompost + PSB) and T10: RDF (20+40+00 kg ha-1 NPK through Fertilizer), respectively. Treatment T10 contributed to raise potassium content in seed, uptake of P and K by cowpea and available NPK in soil after harvest of crop.

Published: September 2022

Background: Blackgram [Vigna mungo (L.) Hepper] is one of the most important cultivated legume crops with high nutritive value and agricultural importance. The productivity of blackgram is not adequate to meet the domestic demand of the growing Indian population. Consequently, there is an urgent need for enhancement of productivity through proper agronomic practices. With this background, a research was conducted to investigate the effect of liquid rhizobium with organic bio-stimulants on growth, yield attributes, yield and economics of irrigated blackgram. Methods: A field experiment was laid out in randomized block design with three replications during 2021 (Kharif and Rabi) season. The treatments include 100% RDF foliar application of Dasagavya, liquid rhizobium, fish amino acid, panchagavya, pink pigmented facultative methylotrophs (PPFM) and sea weed extract with different concentration (1% and 3%, respectively) in addition to control. Result: The experiment results revealed that the application of 100% RDF + liquid rhizobium @ 1% recorded higher growth characters viz., plant height (cm), number of branches plant-1, dry matter production (kg ha-1), leaf area index, yield attributes, grain and haulm yield (kg ha-1). Correlation and regression analysis also indicated that the yield attributes had a positive impact on the grain yield.
El vínculo recíproco entre el diseño de los espacios públicos y las formas de apropiación en Rosario, Argentina (2000-2020)
Authors: Zamler Daiana
Published: September 2022

En las últimas décadas se generalizó la reproducción y renovación de los espacios públicos. Por un lado, como antídoto ante problemas de la vida urbana, y por el otro, para posicionar a las ciudades dentro de un ranking competitivo que persigue lógicas capitalistas globales. Casi veinte años más tarde, se empezó a estudiar la significación de estos espacios para la población. Se demostró que existe una relación recíproca persona-espacio, cargada de percepciones subjetivas y vínculos afectivos que impactan en el bienestar. Se asumió que las cualidades físicas del lugar inciden en la construcción de esos lazos y, por lo tanto, el diseño juega un rol determinante. Entretanto, la transformación urbana de Rosario desde el 2000 tuvo su eje en la renovación y reproducción de sus espacios públicos. Por la preponderancia que alcanzó esta reforma, se seleccionaron dos parques de la costa central, para indagarlos a través de una metodología mixta que permitió investigar la calidad física, de uso y las formas de apego-apropiación. La exploración se hizo a través de un trabajo de campo, encuestas y triangulación de observaciones directas, relevamientos gráficos, fotografías y los resultados de los cuestionarios. En ambos parques se observaron vínculos positivos por parte de los habitantes, sin embargo, el análisis profundo de los resultados demostró cuestiones proyectuales que afectan esos lazos. Por todo lo dicho, es posible replicar este tipo de evaluación a otros casos dentro o fuera de Argentina. Asimismo, es fundamental reflexionar sobre las lógicas de diseño que promuevan el bienestar en la vida urbana actual.

Published: September 2022

Débutée depuis avant l’indépendance avec la création des premières communes, la politique de décentralisation s’est présentée comme une stratégie palliative de l’Etat de Côte d’Ivoire dans la satisfaction des besoins des populations des localités. Mais de plus en plus, les entités décentralisées à l’exemple du Conseil Régional du Tchologo éprouvent des difficultés pour assurer les besoins des populations locales. Cette étude se propose d’analyser le défi du Conseil Régional du Tchologo face à l’accessibilité à l’eau et à l’électricité des populations dans le département de Kong. Ce travail repose sur des enquêtes de terrain effectuées à l’aide d’un questionnaire et de guide d’entretien enrichis par la compilation d’ouvrages relatifs à l’accès à l’eau, à l’électricité et aux réalisations du Conseil Régional dans ces domaines. L’étude révèle qu’avant l’installation du Conseil Régional du Tchologo, l’unique ville de Kong était dotée d’un HVA sur les trois localités urbaines que compte le département. En milieu rural, seulement 20,83 % des villages disposaient d’un HV fonctionnel. Au niveau de l’électricité, 36 villages de plus de 500 habitants n’étaient pas électrifiés. Pour améliorer les conditions de vie des populations dans ces domaines, le Conseil Régional du Tchologo a construit et réhabilité 31 HV dans 25 villages et électrifié 4 villages. En soutien aux actions du Conseil Régional, l’Etat de Côte d’Ivoire a entrepris la réparation ou le remplacement de 302 pompes à motricité humaine dans la région. Au niveau de l’électricité, il s’emploie à électrifier toutes les localités lotis ayant 500 habitants.

The purpose of this mixed methods study was to determine teachers' perceptions of Project Massive Open Online Professional Individualized Learning (MOOPIL) Virtual Professional Development and the role it played in their pedagogical practices as they transitioned from face-to-face to online instruction during the initial months of the COVID-19 pandemic. We applied a mixed method approach to understand the experiences of educators engaged in virtual professional development, virtual mentoring and coaching, and an online learning community during a global pandemic in the Spring of 2020. Participants reported various ways Project MOOPIL impacted their experiences as educators. Teachers’ personal experiences in online learning through Project MOOPIL provided insight into the comparable experiences of students who were immersed in online education as well. Teachers reported a successful transfer of knowledge from this experience to their new distance learning domains that not only catered to the needs of ELs in their classes but to native English speakers as well. Furthermore, through their participation in VPLCs and engagement in Project MOOPIL VMC, participants demonstrated the ability to access and benefit from virtual collaborative support even when life got challenging. In this study, we examined virtual professional development intersectionality, distance learning, and the needs of emergent English speakers.

The Influence of Social Protection on the Poverty in Russian Regions
Authors: Grishina Elena , Tsatsura Elena
Published: September 2022

The influence of social protection system on the poverty level in the regions of Russia was a key question of the article. The regression analysis was carried out using panel data describing the characteristics of the Russian regions from 2013 to 2020. The analysis showed that the regional poverty level may be reduced by the wage increase, scaling up of social transfers and region expenditures for the poor, the increase in the amount of the of regional universal child allowances, the rise of the amount and the coverage of monthly allowance for a child from a poor family, as well as the growth in the amount of benefit to labor veterans. A broader coverage and a higher level of targeted support measures can make a greater contribution to the poverty reduction. At the same time, the increased provision of labor veterans' benefits for the elderly and social allowances for honorary citizens does not have a significant impact on the region poverty level. The results obtained may be additional argument in favor of improving targeting of social support to reduce the regional poverty in Russia. At the same time, it is important to minimize the exclusion errors in targeted social protection programs.

Authors: Guijo Rubio David , Vargas Victor Manuel , Barbero Gómez Javier , Die Jose V , González Moreno Pablo
Published: September 2022

La programación ha sido tradicionalmente una competencia perteneciente a las ingenierías, que recientemente está adquiriendo una importancia significativa en áreas como Ciencias de la Vida, donde resulta fundamental para la resolución de problemas basados en análisis de datos. Entre el alumnado de dichas áreas, se observa una necesidad de mejorar las habilidades relacionadas con la programación aplicadas al análisis de datos. Similarmente, estudiantes de ingeniería con capacidad técnica demostrada pueden carecer de la base temática, igualmente fundamental para la resolución de problemas. Mediante la herramienta del hackathon, y el trabajo en equipo, se ha combinado a especialistas (profesorado y alumnado) de ambas disciplinas a los cuales se enfrentó a una serie de problemas en los campos de la biología, genética, ciencias forestales y ambientales. Para la resolución de estos problemas se utilizaron dinámicas de competición entre los grupos. De cada equipo se valoró la metodología empleada para la obtención de los datos, su análisis, interpretación de resultados, y exposición de las diversas tareas aplicadas para su resolución. El proyecto ha conseguido que el alumnado resuelva los problemas planteados, difícilmente abordables con equipos de una sola titulación, generando un aprendizaje común y una experiencia multidisciplinar para su formación.

Development and Validation of a Simple and Sensitive Reverse-Phase High Performance Liquid Chromatographic Method for the Determination of Ibuprofen in Pharmaceutical Suspensions
Authors: Elias Kenan G. , Hilal Yumen
Published: September 2022

The aim of this work was to develop and validate a rapid and low cost method for estimation of ibuprofen in pharmaceutical suspensions using Reverse-Phase High Performance Liquid Chromatography. The proposed method was conducted and validated according to International Conference on Harmonization (ICH) requirements. The chromatographic parameters were as follows: column of octyldecylsilyl C18 with dimensions (150 × 4.6) mm, mobile phase composed of acetonitrile with phosphoric acid with a ratio of 50 to 50 each using isocratic mode, flow rate of 1.5 mL/min and injection volume of 5 μL. The detection was carried out using UV detector at 220 nm. The method was validated and showed short retention time for ibuprofen peak at 7.651 min, with linearity in the studied range of 0.4 - 1.6 mg/mL (R2 = 0.9999) and with great accuracy ]percent recovery was (100.48%), percent relative error(-1.511-1.465)%[ and repeatability (RSD% = 0.112 for Retention time). The detection and quantitation limits were determined to be 0.036 and 0.110 mg/mL, respectively. This method was applied successfully to determine the content of ibuprofen in three commercial pharmaceutical products. Looking at the short time of analysis and the low limit detection, we recommend this method for routine assays in the quality control laboratories and as a good method for stability studies of ibuprofen.

Published: September 2022

The current study uses the flame fragment deposition (FFD) method to synthesize carbon nanotubes (CNTs) from Iraqi liquefied petroleum gas (LPG), which is used as a carbon source. To carry out the synthesis steps, a homemade reactor was used. To eliminate amorphous impurities, the CNTs were sonicated in a 30 percent hydrogen peroxide (H2O2) solution at ambient temperature. To remove the polycyclic aromatic hydrocarbons (PAHs) generated during LPG combustion, sonication in an acetone bath is used. The produced products were investigated and compared with standard Multi-walled carbon nanotube MWCNTs (95%), Sigma, Aldrich, using X-ray diffraction (XRD), thermo gravimetric analysis (TGA), Raman spectroscopy, scanning electron spectroscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDS) and Transmission Electron Microscopy (TEM). Under the applied experimental circumstances, the obtained characterization data confirm the synthesis of multi-wall carbon nanotubes (MWCNTs) with portion from few wall carbon nanotubes (FWCNTs). The average diameter of synthesized Carbon nanotubes ranged from 31.26 to 78.00 nm, with a purity of more than 65 percent.
A Theoretical Study of the Docking of Medicines with some Proteins
Authors: Ibrahim Ammar Abdulsattar
Published: September 2022

A set of ten drug compounds containing an amino group in the structure were determined theoretically. The parameters were entered into a model to forecast the optimal values of practical (log P) medicinal molecules. The drugs were evaluated theoretically using different types of calculations which are AM1, PM3, and Hartree Fock at the basis set (HF/STO-3G). The Physico-chemical data like (entropy, total energy, Gibbs Free Energy,…etc were computed and played an important role in the predictions of the practical lipophilicity values. Besides, Eigenvalues named HOMO and LUMO were determined. Linearity was shown when correlated between the experimental data with the evaluated physical properties. The statistical analysis was used to analyze the descriptors like multiple linear regression analysis performed to derive quantitative structure-activity relationship models which were further evaluated for the values of the prediction. The correlation coefficient gives an excellent relationship of more than (0.980, 0.980, and 0.978) for AM1, PM3, and HF/STO-3G respectively. A docking study was applied for the interaction of medicines with protein. All the drugs were connected with the protein to give the best energy stability for the docking mixtures. Nepafenac (compound No. 8) had the most stable energy with the protein compared with the 4-Aminosalicylic acid (compound No. 2) which had less energy stability.
Influence of Glow and Afterglow Times on the Discharge Current of Argon at Low Pressure
Authors: Owaid Ahmed Y.
Published: September 2022

An experimental investigation of the variation of argon discharge current with a glow and afterglow time intervals of a square discharge voltage was carried out at low pressure (6-11 mbar). The discharge was created between two circular metal electrodes of diameter (7.5 cm), separated horizontally by a distance (10 cm) at the two ends of a Pyrex cylindrical tube. A composite of two Gaussian functions has been suggested to fit and explain the variation graphs clearly. It is shown that the necessary times of glow and afterglow needed to attain a maximum discharge current are (70 us) and (60 us), respectively. The discharge current is observed to drop to the lowest value when the two times are serially longer than (85 us) and (72 us). Furthermore, the difference between the two times required to obtain a maximum rate of change in the discharge current, or a maximum discharge current, is deduced to be comparable to the breakdown time delay of gases reported in the literature. These observations can be useful for the design of plasma devices requiring specialized engineering.
Cephalometric evaluation of pharyngeal airway space after orthodontic extraction treatment in adult patients with Class II malocclusion: an integration with subjective sleep quality assessment
Authors: Vejwarakul Weerayuth , Ko Ellen Wen-Ching , Lin Cheng-Hui
Published: September 2022

Objectives
This study (1) compared the changes in regional pharyngeal airway space (PAS) after orthodontic treatment among 3 groups of adult patients with Class II malocclusion and (2) identified correlations between questionnaire results and PAS dimensions after orthodontic treatment.
Materials and methods
In this retrospective cohort study, 79 consecutive patients were divided into normodivergent nonextraction, normodivergent extraction, and hyperdivergent extraction groups. Serial lateral cephalograms were used to evaluate the patients’ PASs and hyoid bone positions. The Pittsburgh Sleep Quality Index and STOP-Bang questionnaire were used for sleep quality evaluation and obstructive sleep apnea (OSA) risk assessment, respectively, after treatment.
Results
The greatest airway reduction was observed in hyperdivergent extraction group. However, the changes in PAS and hyoid positions did not differ significantly among 3 groups. The PAS behind the soft palate and tongue was determined to be susceptible to reduction. According to questionnaire results, all 3 groups had high sleep quality and low risk of OSA, with no significant intergroup differences. Moreover, pretreatment-to-posttreatment changes in PAS were not correlated with sleep quality or risk of OSA.
Conclusions
Orthodontic extraction and incisor retraction do not affect the dimensions of pharyngeal airway. Vertical control of Class II skeletal malocclusion, especially in cases involving retrusive chins, can be applied to prevent the worsening of facial profile and to mitigate a tendency of reduction of airway dimensions.
Clinical relevance

Cellular senescence is a state of permanent growth arrest that plays an important role in wound healing, tissue fibrosis, and tumor suppression. Despite senescent cells’ (SnC) pathological role and therapeutic interest, their phenotype in vivo remains poorly defined. Here, we developed an in vivoderived senescence signature using a foreign body response (FBR) fibrosis model in a SnC reporter mouse. We identified pericytes and “cartilage-like” fibroblasts as senescent and defined cell typespecific senescence associated secretory phenotypes (SASP). Transfer learning and senescence scoring identified these two SnC populations along with endothelial and epithelial SnCs in new and publicly available murine and human data single cell RNAseq (scRNAseq) datasets from diverse pathologies. Signaling analysis uncovered crosstalk between SnCs and myeloid cells via an IL34- CSF1R-TGFßR signaling axis, contributing to tissue balance of vascularization and matrix production. Overall, our study provides a senescence signature and a computational approach that may be broadly applied to identify transcriptional profiles and SASP factors produced by SnCs that regulate tissue structure and pathology.

Charcot’s triad, consisting of high fever, abdominal pain, and jaundice, is a well-known clinical feature of acute cholangitis. However, some patients, especially elderly patients, are asymptomatic. We reported herein a case of acute cholangitis in an elderly patient on hemodialysis who was asymptomatic, but whose cholangitis was discovered when a yellow discoloration of her dialyzer was noticed. Blood tests and imaging studies should be performed as soon as possible after noticing yellowish discoloration of dialyzer fibers because asymptomatic acute cholangitis may be present.

Oceanic crust is formed by melt derived from the mantle at oceanic spreading centers. A small amount of melting initiates at about 150-300 km depths in the presence of volatiles (CO2, H2O)1–3, but the extensive dry melting commences at 60-70 km depths due to the upwelling of the mantle as two diverging plates move apart4,5. However, how these melts migrate to the surface and what happens to these melts in the upper part of the mantle are still not understood. Using seismological data recorded by ocean-bottom seismometers, here we report the presence of deep earthquakes at 10-20 km depth in the hot mantle along the Mid-Atlantic Ridge axis, much below the brittle-ductile boundary, suggesting that these earthquakes are caused by a volume change associated with the CO2 degassing from the ascending melt. The geochemical analyses of basalts from the ridge axis show an abnormally high quantity of CO2 (>1.9 wt%) in the primitive melt, confirming the CO2 degassing hypothesis. The large concentration of CO2 in the primitive melt will influence the presence of melt beneath the lithosphere-asthenosphere boundary at sub-solidus temperatures.

To harness the intriguing properties of two-dimensional van der Waals (vdW) ferromagnets (FMs) for versatile applications, the key challenge lies in the reliable material synthesis for scalable device production. Here, we demonstrate the epitaxial growth of single-crystalline 1T-CrTe2 thin films on 2-inch sapphire substrates. Benefiting from the uniform surface energy of the dangling bond-free Al2O3(0001) surface, the layer-by-layer vdW growth mode is observed right from the initial growth stage, which warrants precise control of the sample thickness and atomically smooth surface morphology across the entire wafer. Moreover, the presence of the Coulomb interaction at the CrTe2/Al2O3 interface serves as an effective tuning parameter to tailor the anomalous Hall response, and the structural optimization of the CrTe2-based spin-orbit torque device leads to a substantial switching power reduction by 54%. Our results may lay out a general framework for the design of energy-efficient spintronics based on configurable vdW FMs.

We have analyzed effects of compound events on heat-related health risks by vulnerable groups in Seoul Metropolitan Area, South Korea from 2012 to 2020. A multivariate analysis was conducted for heat-related health impacts by combination of meteorological factors. We have found that heat-related health risks have increased by compound events effects by humidity and solar radiation. Heat-related patients occurred more frequently in higher humidity or intense solar radiation conditions than in usual conditions. All-cause mortalities were higher with high vapor pressure (6.4%, 95% CI: 4.5–8.4%) and large amount of solar radiation (7.5%, 95% CI: 5.2–9.7%) conditions. Infectious and metabolic mortalities have increased about 10% in higher humidity or intense solar radiation conditions. The effects of compound events were different by vulnerable groups. Female’s metabolic mortalities were higher (24.3%, 95% CI: 11.2–37.5%) with solar radiation. The circulatory mortalities of outdoor workers (10.1%, 95% CI: -5.6–25.7%), daytime occurrence (12.5%, 95% CI: 7.6–17.4%), and lower education (13.9%, 95% CI: 7.6–20.1%) has also increased by solar radiation. Mortality of infectious diseases has increased in elderlies (23.5%, 95% CI: 10.3–36.7%) by duration of sunshine. It shows heat waves warnings and policies should consider other meteorological factors other than temperature.

In order to make the carbon footprint minimum, All the countries around the world are trying to increase the penetration of renewable energy in their grids. But during the faults, The microgrids suffer from forced islanding. It is therefore required to enhance the fault ride-through capability of the microgrids, whether DC, AC or Hybrid Microgrids. This will augment their power quality and also support the grids from fault recovery by supplying enough reactive and real power into the grid within 150 ms. ESS will have a hybrid structure in future comprising of batteries, ultra capacitors, fuel cells, flywheels. In this paper,

The optimal conditions for the green synthesis of nano zero-valent iron (G-NZVI) using mango peel extract were investigated using a Box-Behnken Design approach. Three factors were considered, including the ratio of iron solution to mango peel extract ratio (1:1–1:3), feeding rate of mango peel extract (1–5 mL/min), and agitation speed (300–350 rpm). The results showed that the optimal conditions for the synthesis of G-NZVI for arsenate removal were a 1:1 ratio of iron solution to mango peel extract, a mango peel extract feeding rate of 5 mL/min, and an agitation speed of 300 rpm. Under these conditions, nearly 100% arsenate removal was achieved. X-ray diffractometry (XRD), Fourier transform infrared spectroscopy (FTIR), Transmission Electron Microscopy (TEM), Brunauer-Emmett-Teller (BET), and Scanning Electron Microscopy (SEM) with Energy Dispersive X-Ray Analysis (EDX)methods were used to characterize the properties of the G-NZVI. Finally, the arsenate removal efficiency of the G-NZVI was compared against commercial nano zero-valent iron (C-NZVI). The results revealed that the G-NZVI was roughly five times more efficient at arsenate removal than the C-NZVI. The influence of background species such as chloride (Cl−), phosphate (PO43−), calcium (Ca2+), and sulfate (SO42−) was studied to evaluate their effects on arsenite removal. As a result, Cl− and Ca2+ were shown to play a role in promoting arsenite removal, whereas SO42− and PO43− were observed to play an inhibiting role.

Background There is growing interest on how social capital and related social environmental factors impact overall population health and well-being. The nature of migrants’ social environment changes once they migrate to a new context and these changes influence their mental health and well-being. However, there is limited scholarship on how these social environmental factors impact the mental health, well-being, and capacity to flourish of migrant populations. Methods The aim of the study, therefore, was to examine how specific social environmental factors—social networks, social support, and social cohesion at various levels (micro, meso, and macro)—influence the mental health, well-being, and capacity to flourish of migrants in France. We used a qualitative, inductive research design, in collaboration with a community-based organization,Habitat et Humanisme,to conduct 120 semi-structured interviews with migrants and asylum seekers in France. Results Participants described how their usual informal social networks comprised of family and friends had been disrupted since they migrated to France, which impacted their mental health and well-being. Conversely, staying connected with their informal transnational social networks via social media and developing ties with new local informal and formal social networks allowed them to receive different forms of social support, and buffered some of the negative mental health effects. However, the lack of social cohesion impeded migrants’ capacity to flourish. The emerging salient themes depicting a lack of social cohesion included a lack of belonging and marginalization, uprootedness and uncertainty, a lack of identity and security, and current harmful migration-related policies. Conclusion While social support derived from social networks buffered some negative impacts on migrant mental health and well-being, the overall lack of social cohesion ultimately impeded migrants’ capacity to flourish within their host communities, which was further exacerbated by harmful migration policies of exclusion within France. Introducing more inclusive policies related to the governance of migration and an intersectoral approach that views health in all policies is key to promoting social cohesion and flourishing among migrants in France.
