In this current work, we assume the mathematical modelling of non-Newtonian time-dependent hybrid nanoparticles via a cylindrical stenosis artery. In this work, blood is used as a base fluid, and the nanoparticles (copper and aluminum oxide) of cylindrical shape are inserted inside the artery to combine with blood to form hybrid nanofluid (HNF). The homotopy analysis method (HAM) is deployed for the solution of nonlinear resulting equations. For the validation of this current work, the results of the existing work have been compared with our proposed model results. A comparison of key profiles like velocity, temperature, wall shear stress, and flow rate is also performed at a specific critical height of the stenosis. It is also observed that the thermal conductance of hybrid nanofluids is greater than that of nanofluids. Including the hybrid nanoparticles (copper and aluminum oxide) inside the blood enhances the blood axial velocity. These simulations are applicable to the magnetic targeting treatment of stenosed artery disorders and the diffusion of nanodrugs.

Herein the first-principle modeling within the DFT framework is used to investigate the structural, optoelectronic, elastic, and thermoelectric properties of BaMF3 (M = Ag and Cu) ternary halide Perovskites compounds. The computed tolerance factors for BaAgF3 and BaCuF3 are 0.919 and 0.991 respectively, indicating that the cubic crystal phase of these selected compounds is thermodynamically and mechanically stable. It is found that both the compounds are structurally stable according to the Birch-Murnaghan fit curve for optimization. The IRelast package is used for investigating the elastic properties of both cubic compounds and the findings show that these compounds are mechanically stable, scratch-resistant, ductile, anisotropic, and resistant to plastic deformation. The Trans-Blaha modified Becke-Johnson (TB-mBJ) approximation is employed to determine electronic properties with accuracy and precision. The electronic-band structure analysis depicts a narrow band gap semiconductor nature of BaAgF3 and BaCuF3 compounds which displays indirect band gaps of 0.2 eV for BaAgF3 and 0.3 eV for BaCuF3 at the high symmetrical points from (Γ–M). Furthermore, the computations of total densities of states (TDOS) and partial densities of states (PDOS) are carried out to determine how different states contribute to the various band structures. The optical characteristics of BaAgF3 and BaCuF3 are comprehensively examined in 0–40 eV energy ranges. The selected materials possess high optical conduction and absorption coefficients at the high level of photon energies and show transparency at low incident photon energy ranges. The investigations of optical properties led us to the conclusion that BaAgF3 and BaCuF3 are suitable to use in high-frequency UV devices. The thermoelectric properties show that both materials hold high-power factors, electrical conductivity, and figures of merit (ZT), indicating that they are good thermoelectric materials. This is the first theoretical computational systematic analysis of structural, optoelectronic, elastic, and thermoelectric properties of BaMF3 (M = Ag and Cu) that will be experimentally validated to our knowledge.

Abstract Background The Tablo® Hemodialysis System (Tablo) is an all in one, easy-to-learn device featuring integrated water purification, on demand dialysate production and two-way wireless data transmission and is approved for use in the acute, chronic, and home settings. Prior reports have demonstrated Tablo’s ability to achieve clinical goals, seamlessly integrate into hospitals and reduce cost across a wide range of treatment times. Extension of the Tablo cartridge to 24 h allows prolonged therapy and even greater flexibility for prescribers in the acute setting. The objective is to report on the first ever experience with Tablo prolonged therapy between 12 and 24 h in critically ill patients treated at a single-center ICU. Methods Nursing staff were trained during a single training session on Tablo prolonged therapy. After a run-in period of five treatments, Tablo data were collected via real-time transmission to a cloud-based, HIPAA compliant platform and reviewed by site staff. Dialysis treatment delivery, clinically significant alarms, and clotting events were recorded. Sub-group analysis between COVID-19 positive and negative patients were reported. Results One hundred (100) consecutive Tablo prolonged treatments had a median prescribed treatment time of 24 h and a median achieved treatment time of 21.3 h. Median cartridge usage was 1.3 per treatment. The dialysis treatment time was delivered in 91% of treatments, with 6% ending early due to an alarm, and 3% ending due to clotting. Clinically significant alarms occurred at a median rate of 0.5 per treatment hour with a resolution time of 18 s. Median blood pump stoppage time related to these alarms was 2.3 min per treatment. Blood pump stoppage time was higher in the COVID-19 subgroup when compared to the non-COVID-19 subgroup. Conclusion Tablo successfully achieves prescribed treatment time with minimal therapy interruptions from alarms or cartridge changes. This data demonstrates the effectiveness of Tablo in achieving personalization of treatments necessary for unstable patients and enabling successful delivery of extended therapy with minimal clotting. Tablo’s prolonged therapy meets the needs of critically patients, including COVID-19 positive patients, requiring renal replacement therapy for greater than 12 h.

This study reports the antioxidant and protective properties of three dietary plants, Taraxacum officinale, Cichorium intybus and Lectuca sativa on lipid peroxidation in mice liver. Extracts showed significant (p = 0.0392) inhibition against thiobarbituric acid reactive species (TBARS) induced using the pro- oxidants iron (10 μM FeSO4) and sodium nitroprusside (5 μM) in liver homogenates of mice. Free radical scavenging activity was evaluated by the quenching of DPPH radical (p=0.00236). Extracts also showed metal chelating activities (p=0.00143) and high antioxidant activity in phosphomolybdenum assay (p=0.00246). The high content (p=0.000243) of phenolics and flavonoids were detected in aqueous extracts of the plants which may be responsible for antioxidant activities. Taraxacum officinale comparatively showed higher antioxidant activities followed by Cichorium intybus and Lectuca sativa. It is concluded that polyphenolic-rich extracts of studied plants are potential sources of natural antioxidants.

Wide bandgap semiconductors are very interesting due to their high frequency applications. Perovskite have proved to be most stable structures useful for many applications e.g. Solar cells, detectors etc. The current work is based on the prediction of two new competitors (InXF3 (X= Be and Sr)) for the use in high frequency applications. The modelling and simulations were performed by adopting state of the art packages; WIEN2k and BoltzTrap2. The most accurate and precise exchange-correlation of TB-mBJ (Trans and Blaha modified Becke-Johnson) potential interfaced within wien2k is utilized for obtaining better results. The results showed that the selected compounds possess a cubic crystal structure with a space group of Pm-3m (#221). The Goldschmidt's tolerance factor (τ) is determined and is found to be 0.96 for InBeF3 and 0.92 for InSrF3 which indicates the stability of the compounds in cubic phase. The unit cell crystal structural optimization is done to evaluate the ground state lattice parameters. The direct band gap of 2.23 eV and 3.58 eV from (X-X) exists for InBeF3 and InSrF3 compounds respectively. The optical properties are computed and analyzed from the optical dielectric function for both the compounds within the energy range of 0 eV to 40 eV and the results depict that these materials are more sensitive at higher energy range, possess high absorption and optical conductivity in good agreement with electronic band structure. Mechanically these compounds are stable, ductile, anisotropic, and hard to scratch. The thermoelectric properties are evaluated for InXF3 (X= Be and Sr) compounds up to a temperature range of 1000 K. This work can open new opportunities for further exploration in this field.

Background: Diesel mainly consists of paraffin and thio-aromatic compounds. Sulfur present in diesel exhaust is the major challenge for oil refineries. Sulfur is an oxidizing element that discharges as acute pollutant in the environment which has adverse effects on human and on animal life. Introduction: The scope of this review paper is to discuss and to highlight the recent advancements in process of desulfurization of diesel oil to explore the less energy intensive and more economical process. Methods: Recently, different techniques are widely used for desulfurization of diesel oil to remove sulfur containing compounds from diesel. These techniques mainly involve hydrodesulfurzation, oxidative desulfurization, biodesulfurization, ionic liquid desulfurization, and adsorption desulfurization. Conclusion: Adsorptive desulfurization technique is green, less energy incentive, and more economical technique than hydro-desulfurization, oxidative desulfurization, ionic liquid desulfurization and bio desulfurization. Optimization of adsorptive desulfurization technique may yield up to 100% desulfurization of diesel oil.

- Abstract
Despite the widespread concern with social protection in the field of development, it has had little impact on displacement until very recently. UNHCR has had a Social Protection Unit since 2009, but social protection is barely mentioned in either the Global Compact on Refugees or the Global Compact for Safe, Orderly and Regular Migration, both agreed in 2018. The period since 2018 has seen a growth of research interest and new policy development. This represents the latest appearance of the humanitarian-development nexus in the field of displacement. This nexus is a long-standing one and is inherent in the term ‘durable solution’ as the only effective end of displacement. Unfortunately, there are few recognised successes, and durable solutions are enjoyed by only a tiny proportion of the growing number of displaced people in the world today. This makes renewed attention to the humanitarian-development nexus all the more urgent. In this paper we review the relationship between a humanitarian response to initial displacement and longer-term development planning, as well as the recent range of research and policy responses in this field. These demonstrate significant potential of social protection. We go on to consider six areas of developing theorisation in order to inform what would constitute success in the expanding inclusion of displaced people in social protection programmes or systems. We conclude with four suggestions where further research in this area can help to determine how and if the potential for social protection to offer more sustainable responses to displacement is being realised.

The use of social protection measures has garnered increasing attention in recent years from academics and policymakers aspiring to unite the humanitarian origins and development ambitions of displacement governance regimes. Much of this attention has been focused on establishing and strengthening national systems of social protection provision. Analysis of policy approaches to social protection has become increasingly detailed, but typically does not extend beyond formal rights-based provision. This article seeks to address the paucity of literature on how refugees strategise around access to social assistance beyond Northern-mandated approaches. We review existing research on Syrian displacement in Lebanon to interrogate assumptions that refugees automatically seek institutionalised assistance. Drawing on postcolonial literature, we explore why modalities of social and humanitarian assistance offered through a rights-based approach represent only a partial mapping of the social protection that refugees avail themselves of. In doing so, we signal a move beyond the narrow and restrictive binary of formal/informal and attempt to consider the range of social protection opportunities from the perspective of refugees. Though unequal, we argue that both national systems of social protection provision and alternative approaches identified by displaced people are currently necessary, although a language of rights is only applicable to the former. Ultimately, greater coordination between the two is required. In conclusion, this article describes directions for future research aimed at a holistic understanding of how social protection is accessed in displacement and a more explicit interrogation of the impact of social protection measures in displacement settings.

35. Displacement and Social Assistance

- Abstract
Displacement forms part of virtually any major crisis. It introduces a level of complexity when providing social assistance that leads to a specific, usually context-dependent set of challenges. It is widely recognised that the vast majority of displaced people will travel as short a distance as possible to reach safety, whether as Internally Displaced Persons (IDPs), refugees or irregular migrants in neighbouring countries. Displaced people are disproportionately hosted in low- and middle-income countries, and the length of their displacement is increasing. This highlights the urgent priority of displacement; indeed, it has received sustained attention from the highest levels of global decision-making, particularly since 2016, including two Global Compacts in 2018 (Global Compact for Migration, Global Compact for Safe, Orderly and Regular Migration). Although some have argued that such global summits offer a replacement for meaningful action, these events at least highlight clear political will to shift the emphasis from humanitarian responses to a much longer-term development focus. Interest in social assistance and displacement has also grown since 2018 and resulting policy must respond to this concern for more sustainable responses. High-level commitments are slowly filtering through to policy, while recent research has provided clear frameworks for analysing developing policy approaches. Gaps remain in the analysis of policy implementation and in the assessment of how to access social assistance beyond official state channels.

36. Beyond Rights-Based Social Protection for Forcibly Displaced People

- Abstract
Having a right that is not respected is not the same as having no right at all. At least this should not be the case. Failure to receive something to which you are entitled should lead to formal redress or failing that, protest. The rights-based discourse has a wider importance. If and when it is or should be used is significant. In terms of access to social protection (including social and humanitarian assistance), the rights-based discourse means there is no difference between refugees and others who fail to receive the protection to which they are entitled, such as Internally Displaced People (IDPs). This introduces two key tensions, both of which we explore in this paper. The first concerns the identification of the institution responsible for fulfilling the right, as determined in state-led/formal humanitarian system of social protection. The second concerns the alternatives displaced people may identify when Northern mandated forms of social protection fail, or when the conditions for the enjoyment of that protection are too onerous. These alternatives constitute a second system of social protection. We conclude that although they are unequal, both systems are currently necessary, even as a language of rights is only appropriate in relation to the first tension. Ultimately greater coordination and collaboration between the two systems is necessary.

To use gold and copper ions for ion implantation through 1-MV pelletron accelerator, gold and copper targets were bombarded with low energy cesium ions applying source of negative ions by cesium sputtering (SNICS). This work aims to investigate the cluster dynamics of these noble metals in a low energy range so that optimized data can be obtained for the use of these cluster ions in ion implantation. Negative ions including monomers and clusters of both metals were detected which were mass analyzed. Cu clusters up to Cu[Formula: see text] and gold clusters up to Au[Formula: see text] were emitted. The minimum energy of cesium ions to produce enough cluster ions so that they could be detected by a mass analyzer has been determined. The data was analyzed to measure sputtering yield, total sputtering yield and normalized number density of different sputtered species. In this energy range, the sputtering behaviors of Cu remain almost constant but in the case of Au there is a slight increase in cluster sputtering probability with an increase in incident ion energy. The sputtering yield of clusters decreases according to the power-law, i.e. [Formula: see text]. Power law exponent in the case of copper has an average value of [Formula: see text] whereas exponent in the case of gold clusters changes from 3.5 to 6.

RATIONALE AND OBJECTIVE: The safety of intensive blood pressure (BP) targets is controversial for persons with chronic kidney disease (CKD). We studied the effects of hypertension treatment on cerebral perfusion and structure in those with and without CKD. STUDY DESIGN: Neuroimaging substudy of a randomized trial. SETTING & PARTICIPANTS: A subset of participants in the Systolic Blood Pressure Intervention Trial who underwent brain MRI studies. Presence of baseline CKD was assessed by estimated glomerular filtration rate (eGFR) and urine albumin to creatinine ratio (UACR). INTERVENTION: Participants were randomly assigned to intensive (systolic BP 30 mg/g (N=151), the effects of intensive versus standard BP treatment on change in global cerebral blood flow, WMLs and total brain volume were 1.91 ml/100g/min (95% CI −3.01, 6.82), 0.003 cm(3) (asinh transformed, 95% CI −0.13, 0.13), and −7.0 cm(3) (95% CI −13.3, −0.3), respectively. The overall treatment effects on cerebral blood flow and total brain volume were not modified by baseline eGFR or UACR; however the effect on WMLs was attenuated in participants with albuminuria (interaction p-value 0.04). LIMITATIONS: Measurement variability due to multi-site design. CONCLUSIONS: Among hypertensive adults with primarily early kidney disease, intensive versus standard blood pressure treatment did not appear to have a detrimental effect on brain perfusion or structure. The findings support the safety of intensive blood pressure treatment targets on brain health in persons with early kidney disease. FUNDING: The Systolic Blood Pressure Intervention Trial was funded by the National Institutes of Health (including the National Heart, Lung, and Blood Institute, the National Institute of Diabetes and Digestive and Kidney Diseases, the National Institute on Aging, and the National Institute of Neurological Disorders and Stroke), and this substudy was funded by the National Institutes of Diabetes and Digestive and Kidney Diseases. TRIAL REGISTRATION: SPRINT was registered at ClinicalTrials.gov with the study number NCT01206062.

Introduction Corona-virus Disease 2019 (COVID-19) has had a huge impact on the delivery of healthcare worldwide, particularly elective surgery. There is a lack of data regarding risk of postoperative COVID-19 infection in children undergoing elective surgery, and regarding the utility of pre-operative COVID-19 testing, and preoperative “cocooning” or restriction of movements. The purpose of this present study was to examine the safety of elective paediatric Otolaryngology surgery during the COVID-19 pandemic with respect to incidence of postoperative symptomatic COVID-19 infection or major respiratory complications. Materials and methods Prospective cohort study of paediatric patients undergoing elective Otolaryngology surgery between September and December 2020. Primary outcome measure was incidence of symptomatic COVID-19 or major respiratory complications within the 14 days after surgery. Parents of prospectively enrolled patients were contacted 14 days after surgery and enquiry made regarding development of postoperative symptoms, COVID-19 testing, or diagnosis of COVID-19. Results 302 patients were recruited. 125 (41.4%) underwent preoperative COVID-19 RTPCR testing. 66 (21.8%) restricted movements prior to surgery. The peak 14-day COVID-19 incidence during the study was 302.9 cases per 100,000 population. No COVID-19 infections or major respiratory complications were reported in the 14 day follow up period. Conclusion The results of our study support the safety of elective paediatric Otolaryngology surgery during the pandemic, in the setting of community incidence not exceeding that observed during the study period., Graphical abstract Image 1

To better understand the range of possibilities and opportunities for (co)existence available to displacement‐affected people, attention must be given to the thick webs of sociality shaping interactions in situations of mass displacement. This paper makes the case that refugee squats in Athens are distinct spaces wherein different understandings of (co)existence converge – spaces whose production is contingent on support from neighbourly relations and networks that are mediated in moments through conceptions of conviviality informed by religion. Based on ethnographic work carried out in 2016 and a spatial analysis of refugee squats in Athens, this paper emphasises neighbourliness and conviviality as they relate to sacred understandings of coexistence. This helps highlight the limits built in to thinking about the movement of refugees from the global South through Euro‐centric ontologies of the social. More than this, following postcolonial debates on the decentring of knowledge production, the research makes manifest how Islamic socio‐cultural memories of jiwār or a right of neighbourliness complicate geographies of humanitarianism that make stark binary assumptions between religious and secular space. In turn, the evidence from Athens indicates that refugee perspectives on neighbourliness are imperfectly translated by migrant rights activists as solidarity, obscuring the different ways Muslim structures of feeling contribute to the production of refugee squats.

In this paper I make the case that a closer examination of the tradition of jiwār or neighbourliness can help unsettle the binary of citizen and migrant that forecloses the possibility of accessing rights for the latter. Here, insights from human geography and social anthropology pertaining to understandings and practices of conviviality are mobilised to ask what contemporary readings of jiwār can tell us given that the nation-state dominates modalities and practices of locality production. Mobilising interview and ethnographic research material produced in partnership with Palestinian, Syrian, Sudanese, and Iraqi forced migrants over the past 8 years across multiple sites, this paper draws attention to the significance of creating and maintaining neighbourly relations and spaces as an ethical position contrasted against exclusionary nation-state and sectarian discourses and practices. Here, I draw on the Turkish state response to on-going Syrian displacement and the Syrian state’s response to the earlier displacement of Iraqis (2005-11) to illustrate how the sedentarist logic of the nation-state impedes practices of conviviality that emerge from the lived realities of encounter between those already resident and those who newly arrive.
