Authors: El-Bassuony Asmaa.A. H. , Gamal W. M. , Abdelsalam H. K. 
Published: May 2022

AbstractIn this work, the effects of silver nanoferrite and nanochromite (Ag2Fe2O2, Ag2Cr2O4) were studied using the flash auto-combustion technique. Numerous physical properties were clarified from the different structures determined from the x-ray examination such as lattice parameter the cation dispersion, oxygen parameter, hopping length, and interatomic distance. Among antimicrobial properties, Ag addition to both samples showed high efficacy against both types of tested bacteria (gram-positive and gram-negative); however, they showed moderate effect against Candida albicans fungus. No activity appeared against Aspergillus flavus fungus for both samples. The switching field and high-frequency response of Ag2Fe2O4 and Ag2Cr2O4 nanoparticles were studied from the magnetic properties. Ag2Cr2O4 nanoparticles are expected to be used for high-frequency applications more than Ag2Fe2O4 ones. As a result of all previous analyses, the applications of this study promote the use of Ag2Fe2O4 nanoferrite and Ag2Cr2O4 nanochromite for high-frequency, switching field, and biomedical applications as antimicrobial nanomaterials.

Published: May 2022

Abstract
Background
Refugee women who leave their country due to persecution and violence have multiple barriers to sexual and reproductive health (SRH) services. The COVID-19 pandemic added an additional barrier to in-person reproductive health education, dialogue, and clinical care. This study aimed to assess the potential of using virtual group meetings as a forum for refugee women to learn about and discuss reproductive health concerns such as cervical cancer screening, family planning, childbirth, and postpartum care.

Method
We conducted semi-structured interviews with 36 refugee women and stakeholders to assess factors that impact refugee women’s receptiveness for virtual platforms to obtain information and engage in discussions on reproductive health. Thematic analysis was conducted using the software Dedoose.

Results
Openness to engage in virtual platforms varied by refugee community, women’s demographic, and life experience. The women’s involvement with local refugee groups facilitated their engagement with virtual platforms. Furthermore, individuals’ family structure and marital relationship, along with literacy and English proficiency, and access to and familiarity with technology impacted engagement. Virtual groups needed to mirror confidentiality and women expressed a strong preference that groups were all-women.

Conclusion
Refugee women are receptive to virtual groups on SRH when they are offered in a culturally appropriate manner that considers the living situations and access to technology after arrival to the USA. Findings from this study provide a framework to develop and tailor effective virtual or hybrid virtual-in-person programs for women in refugee communities.

Abstract
Laser powder bed fusion (L-PBF) success in the industrial scenario strongly depends on the ability to manufacture components without defects and with high building rates, but also on the ability to effectively control the microstructure to gain the required properties in the final component. In this regard, the recently developed numerical simulation software of L-PBF technologies can represent an effective tool, since many of them provide solidification data (i.e. temperature gradient and cooling rate) useful for microstructure prediction. In this work, a numerical model was applied to simulate the processing of four single scan tracks of 316L stainless steel processed with different parameters. Temperature and cooling rate around the melt pool were extracted from the numerical model and used to estimate the microstructure cellular arm spacing and the microhardness. Experimental measurements were then compared with the estimated values revealing good agreement. The good agreement between experimental and estimated values shows the advantages of the proposed method for microstructure and microhardness prediction based on numerical modelling as a useful resource for process optimization according to the required final microstructural features.

A Short Note on the Aftershock Duration of Strong to Major Himalayan Earthquakes
Authors: Gupta Harsh K. , Rekapalli Rajesh 
Published: May 2022

Abstract
Earthquakes of M ≥ 5 tend to be locally damaging, specifically when these are the aftershocks of larger earthquakes, as the main shock would have weakened the structures. For the rescue operations and general well-being of the local residents, it is helpful if an estimate is available as to how long M ≥ 5 aftershocks would continue to occur. Earthquakes M ≥ 6.5 tend to be followed by aftershocks of M ≥ 5. In this study, aftershock sequences of seven earthquakes of magnitude M ≥ 6.5 were analyzed. Six among these are in the Himalayan region and the remaining one is in the near vicinity in China. The analysis suggests that the number of M ≥ 5 aftershocks and the duration of their occurrence decrease with the decrease of the mainshock magnitude. For the 2008 Sichuan earthquake of M 7.9 there were 136 M ≥ 5 aftershocks, while for 1975 Kinnaur earthquake of M 6.8 there were only 9. The aftershock duration of the Himalayan region earthquakes obeys the exponential law T = AecM, where the A and c are constants associated with regional fault settings. This relation is helpful in providing an estimate of the time for which M ≥ 5 aftershock activity would continue after the occurrence of a M ≥ 6.5 earthquakes.
Reserves and Resources of Iron Ores of India – A Perspective
Authors: Krishnamurthy K. V. 
Published: May 2022

Abstract
With a total resource of 22,487 million tonnes of haematite (Fe2O3) and 10,789 million tonnes of magnetite (Fe3O4), India ranks seventh among the countries to possess abundant iron ore resources, in the world. India is not only one of the leading producers of iron ore but also at present second largest manufacturer of steel in the world (2021). Though the country can boast of huge good quality iron ore resources, the percentage of reserves to total resources is quite dismal as only 5,422 million tonnes (24%) of haematite and mere 53 million tonnes (0.49%) of magnetite resources are categorised as reserves as on 1.4.2015 as per UNFC categorisation. It is a matter of great concern that with rapid expansion in the steel manufacturing capacity, there will be unprecedented demand for iron ore for domestic consumption, since it is estimated that by the year 2030 India is likely to produce 300 m.t. of steel to meet the ever-growing domestic demand. Besides, India is likely to continue its iron ore export to keep the structural balance in the international market. In such a situation, can India equip itself to meet the surging demand for iron ore and what should be the strategy for the country not only to augment its iron ore resources but also to enhance its reserve base to a respectable level. This paper attempts to analyse the existing iron ore resources vis-a-vis demand-supply balance of iron ore for the year 2029-30, considering the pros and cons of the existing government policies.

Published: May 2022

Abstract
Accurate watershed delineation and drainage system extraction are critical tasks for the hydrological and geomorphological model. Watershed morphology evaluation is very important for flood control and recovery planning. It is beneficial for understanding the basin’s hydrology. In this study, the Rel river basin was selected, located in Gujarat, India. This study deals with the runoff potential in the semi-gauged Rel river basin depending on the detailed morphometric study. The Survey of India (SOI) topographic sheet (1:50000) and geographical information system (GIS) tools have been used for the detailed study in the evaluation of morphometric parameters. For accuracy in flat terrain, a topographic sheet has been used instead of DEM. Manually digitise the drainage from the SOI topographic sheet to precisely divide the watershed boundary; after that, the Rel basin has been divided into five sub-watersheds (SWs), namely, SW1 SW2, SW3, SW4 and SW5. Twenty-eight morphometric parameters have been calculated for each sub-watershed (SW). For runoff potential, twenty-one effective morphometric parameters have been selected based on previous studies.A compound factor (CF) model has been used for the SWs prioritisation. Twenty-one effective morphometric parameters have been considered in the CF model. The model results indicated that SW2 has a very-high runoff potential, and SW3 has a very-low runoff potential. The methodology developed and the results presented here will be critical in developing a comprehensive sub-watershed management plan. The work’s results can better understand the topography, nature of the basin, and the delineation of a suitable soil conservation site and mitigate flash floods in the flat region.
Understanding the Contaminant Chemistry of Water Resources at Urban Solid Waste Disposal Site, Hyderabad, India

Published: May 2022

Abstract
The Hyderabad urban solid waste dump site, though located on a rocky hillock, has a highly weathered mantle apart from an interconnected network of fractures. These hydrological features favored massive dissipation of contaminants into the surface as well as sub-surface water resources. The surface water bodies in the vicinity turned into leachate pools and groundwater in the zone of influence is not fit for any use. Both surface (15) and groundwater (79) samples were collected during 2011 and 2012 hydrological cycles and tested for major parameters. A few samples (15) of 2012 were also analyzed to determine TOC, BOD, and COD. The general order of abundance of prominent ion species in groundwater was Cl-, Ca2+, Na+, Mg2+, HCO3- and SO42-. A very high and similar Clconcentration in surface water (37 meq/l) and contaminated groundwater (40 mq/l) establish that solid waste stockpile was the point source through leachate. The presence of high (&gt;200 mg/l) TOC, BOD, and COD in many surface and groundwater samples supports the inference. Modified Piper plots display the Ca-Mg-Cl and Ca-Mg-HCO3 were the dominant hydrochemical facies in groundwater, whereas many surface water and few groundwater samples belong to Na-Cl/SO4 type. A good correlation (~0.90) between Cl- - Ca2+, TH, Na+, and Mg2+ points out that these ion species were from the same source. Gibbs plots, positive CAI-1 and 2, together with &gt;2 ratios of Ca2+/Mg2+, Cl-/Na+ in many samples divulge water-rock interaction and ion exchange were also controlling the hydrochemistry. The low HCO3-/Cl-, TA/TH and SO42-/HCO3- values indicate an insufficient influx of freshwater and non-lithogenic sources altered the groundwater chemistry. Favorable hydrochemistry in the form of alkaline water, high TH, Cl- and prevailing redox conditions as well as methanogenic phase of dump yard might have spurred up ion enrichment activity within the zone of influence of point source.

Abstract
Purpose
Synovial sarcoma (SySa) is a rare soft tissue tumor characterized by a reciprocal t(X;18) translocation. The chimeric SS18-SSX fusion protein represents the major driver of the disease, acting as aberrant transcriptional dysregulator. Oncogenic mechanisms whereby SS18-SSX mediates sarcomagenesis are incompletely understood, and strategies to selectively target SySa cells remain elusive. Based on results of Phospho-Kinase screening arrays, we here investigate the functional and therapeutic relevance of the transcription factor CREB in SySa tumorigenesis.

Methods
Immunohistochemistry of phosphorylated CREB and its downstream targets (Rb, Cyclin D1, PCNA, Bcl-xL and Bcl-2) was performed in a large cohort of SySa. Functional aspects of CREB activity, including SS18-SSX driven circuits involved in CREB activation, were analyzed in vitro employing five SySa cell lines and a mesenchymal stem cell model. CREB mediated transcriptional activity was modulated by RNAi-mediated knockdown and small molecule inhibitors (666-15, KG-501, NASTRp and Ro 31-8220). Anti-proliferative effects of the CREB inhibitor 666-15 were tested in SySa avian chorioallantoic membrane and murine xenograft models in vivo.

Results
We show that CREB is phosphorylated and activated in SySa, accompanied by downstream target expression. Human mesenchymal stem cells engineered to express SS18-SSX promote CREB expression and phosphorylation. Conversely, RNAi-mediated knockdown of SS18-SSX impairs CREB phosphorylation in SySa cells. Inhibition of CREB activity reduces downstream target expression, accompanied by suppression of SySa cell proliferation and induction of apoptosis invitro and in vivo.

Conclusion
In conclusion, our data underline an essential role of CREB in SySa tumorigenesis and provides evidence for molecular targeted therapies.

Published: May 2022

Abstract
Purpose
The benefits of antiviral treatment with remdesivir in hospitalized patients with COVID-19 remain controversial. Clinical analyses are needed to demonstrate which patient populations are most likely to benefit.

Methods
In a retrospective monocentric analysis, patients with COVID-19 treated between July 1, 2020 and June 30, 2021 at Hospital St. Georg, Leipzig, Germany were evaluated. The primary endpoint was time to clinical improvement, and the secondary endpoint was 28-day mortality. Propensity score matching was used for the endpoint analysis.

Results
A total of 839 patients were fully evaluated, 68% of whom received specific COVID-19 drug therapy. Remdesivir was used in 31.3% of the patients, corticosteroids in 61.7%, and monoclonal antibodies in 2.3%. While dexamethasone administration was the most common therapeutic approach during the second pandemic wave, combination therapy with remdesivir and corticosteroids predominated during the third wave. Cox regression analysis revealed that combination therapy was not associated with faster clinical improvement (median: 13 days in both matched groups, HR 0.97 [95% CI 0.77–1.21], P = 0.762). By contrast, 28-day mortality was significantly lower in the corticosteroid-remdesivir group (14.8% versus 22.2% in the corticosteroid group, HR 0.60 [95% CI 0.39–0.95], P = 0.03) in the low-care setting. This effect was also demonstrated in a subgroup analysis of patients with remdesivir monotherapy (n = 44) versus standard of care (SOC).

Conclusion
In COVID-19 patients with only mild disease (low-flow oxygen therapy and treatment in a normal ward) who received corticosteroids and/or remdesivir in addition to SOC, early administration of remdesivir was associated with a measurable survival benefit.

AbstractHigh-entropy oxides (HEOs) are a new class of emerging materials with fascinating properties (such as structural stability, tensile strength, and corrosion resistance). High-entropy oxide coated Ni-rich cathode materials have great potential to improve the electrochemical performance. Here, we present a facile self-ball milling method to obtain (La0.2Nd0.2Sm0.2Eu0.2Gd0.2)2Zr2O7 (HEO) coated LiNi0.8Co0.1Mn0.1O2 (NCM811). The HEO coating endows NCM811 with a stable surface, reduces the contact with the external environment (air and electrolyte), and inhibits side reactions between cathode and electrolyte. These favorable effects, especially when the coating amount is 5 wt%, result in a significant reduction of the battery polarization and an increase in the capacity retention from 57.3% (NCM811) to 74.2% (5HEO-NCM811) after 300 cycles at 1 C (1 C = 200 mA·h·g−1). Moreover, the morphology and spectroscopy analysis after the cycles confirmed the inhibitory effect of the HEO coating on electrolyte decomposition, which is important for the cycle life. Surprisingly, HEO coating reduces the viscosity of slurry by 37%–38% and significantly improves the flowability of the slurry with high solid content. This strategy confirms the feasibility of HEO-modified Ni-rich cathode materials and provides a new idea for the design of high-performance cathode materials for Li-ion batteries.

AbstractCoastal and marine cultural heritage (CMCH) is at risk due to its location and its often indefinable value. As these risks are likely to intensify in the future, there is an urgent need to build CMCH resilience. We argue that the current CMCH risk management paradigm narrowly focuses on the present and preservation. This tends to exclude debates about the contested nature of resilience and how it may be achieved beyond a strict preservationist approach. There is a need, therefore, to progress a broader and more dynamic framing of CMCH management that recognises the shift away from strict preservationist approaches and incorporates the complexity of heritage’s socio-political contexts. Drawing on critical cultural heritage literature, we reconceptualise CMCH management by rethinking the temporality of cultural heritage. We argue that cultural heritage may exist in four socio-temporal manifestations (extant, lost, dormant, and potential) and that CMCH management consists of three broad socio-political steering processes (continuity, discontinuity, and transformation). Our reconceptualisation of CMCH management is a first step in countering the presentness trap in CMCH management. It provides a useful conceptual framing through which to understand processes beyond the preservationist approach and raises questions about the contingent and contested nature of CMCH, ethical questions around loss and transformation, and the democratisation of cultural heritage management.
Are Distressed Black Women Also Depressed? Implications for a Mental Health Paradox

Published: May 2022

AbstractPurposeRecent research suggests the determinants of and links between psychological distress and psychiatric disorder are distinct among Black Americans. Yet, these associations have not been explored among Black women, despite the unique social experiences, risks, and mental health patterns they face. The present study assessed the sociodemographic and psychosocial determinants of distress and disorder and evaluated the distress–disorder association, including whether it was conditional on sociodemographic and psychosocial characteristics among Black women.MethodsData were from 328 Black women in the Nashville Stress and Health Study, a cross-sectional community epidemiologic survey of Blacks and Whites in Nashville, Tennessee, and was used to assess the correlates of distress (CES-D depressive symptoms scale) and major depressive disorder (MDD; based on the CIDI). Multinomial logistic regression models estimated the extent to which greater distress was associated with higher risk of “chronic” or “resolved MDD”.ResultsStress exposure and marital status were associated with greater distress, while stress exposure and childhood SES were associated with elevated disorder risk. Although increased distress was associated with greater disorder risk, significant interactions indicated these associations depend on differences in age and adult socioeconomic status within this population.ConclusionsThis study identifies distinct correlates of distress and disorder and shows that the distress–disorder association varies among subgroups of Black women. Results have important implications for public health research and practice, as they highlight the factors that matter most for the mental health outcomes of Black women.

Published: May 2022

AbstractThe family plays an important role in adolescents’ social development. Yet there is little information about the impact of family climate on adolescents’ social adaptation, and the term “family climate” is seldom clearly defined and is usually related to other concepts, such as family systems or family environments. To understand the core of family climate, this study conducted a systematic review to analyze research about family climate associated with adolescents’ social adaptation in community samples. A search of empirical research published over the last 20 years identified 12 relevant studies. The studies revealed that family climate can mainly be described in terms of cohesion, conflict, organization, adaptability, and expressiveness. Family climate was shown to be a good predictor of both problem-solving skills and violence in relationships and exhibited further associations with other aspects of social adaptation. This review revealed a need for more systematic and longitudinal research on family climate in community samples.
