Combined Marangoni and Buoyancy Convection in a Porous Annular Cavity Filled with Ag-MgO/Water Hybrid Nanofluid
Authors: Al-Mdallal Qasem M. , Kanimozhi B. , Muthtamilselvan M. , Abdalla Bahaaeldin 
Published: February 2022

Background:
This article numerically examines the effect of buoyancy and Marangoni
convection in a porous enclosure formed by two concentric cylinders filled with Ag-MgO water hybrid
nanofluid. The inner wall of the cavity is maintained at a hot temperature, and the outer vertical
wall is considered to be cold. The adiabatic condition is assumed for the other two boundaries. The
effect of the magnetic field is considered in radial and axial directions. The Brinkman-extended Darcy
model has been adopted in the governing equations.

Methods:
The finite difference scheme is employed to work out the governing Navier-Stokes equations.
The numerically simulated outputs are deliberated in terms of isotherms, streamlines, velocityand
average Nusselt number profiles for numerous governing parameters.

Results:
Except for a greater magnitude of axial magnetic field, our results suggest that the rate of
thermal transport accelerates as the nanoparticle volume fraction grows. Also, it is observed that
there is an escalation in the profile of average Nusselt numberwith an enhancement in Marangoni
number.

Conclusion:
Furthermore, the suppression of heat and fluid flow in the tall annulus is mainly due to
the radial magnetic field whereas in the shallow annulus, the axial magnetic field profoundly affects
the flow field and thermal transfer.

Published: February 2022

Abstract:
Hematopoietic stem cells (HSCs) have self-renewal as well as pluripotency properties and are
responsible for producing all types of blood cells. These cells are generated during embryonic development
and transit through various anatomical niches (bone marrow microenvironment). Today, they are
easily enriched from some sources, including peripheral blood, bone marrow, and umbilical cord blood
(UCB). HSCs have been used for many years to treat a variety of cancers and blood disorders such as
various types of leukemia, lymphoma, myelodysplastic, myeloproliferative syndromes, etc. Although
almost 50 years have passed since the discovery of stem cells and numerous investigations on cell therapy
and regenerative medicine have been made, further studies need to be conducted in this regard. This manuscript
review the history, location, evolution, isolation, and therapeutic approaches of HSCs.
Electron Communications and Correlations in Subsystems
Authors: Nalewajski Roman F. 
Published: February 2022

Abstract:
The quantum entanglement of molecular fragments in reactive systems is approached.
The "external" (inter-fragment) and “internal” (intra-fragment) correlation energies
are expressed in terms of the DFT average correlation holes resulting from the coupling
constant integration of the scaled electron repulsion terms in the electronic Hamiltonian. Information
networks in the local and configuration resolutions are examined, and their conditional
entropy (covalency) and mutual information (iconicity) descriptors are summarized.
The local channels in the single Slater determinant approximation of HF theory are explored
in some detail. The multisite events in the bond system for the specified molecular state are
tackled, cascade (bridge) propagations are examined, and the Fermi (exchange) correlation
of HF theory is discussed. The partial density matrices of interacting fragments are introduced,
and their role in shaping the ensemble averages of physical observables and effective
communications within reactants is examined.
Polyelectrolyte-Surfactant Mixtures as the Model for Understanding the Performance of 2-in-1 Shampoo Formulations
Authors: Guzmán Eduardo 
Published: February 2022

Background:
2-in-1 shampoos are very complex multi-component mixtures used for the cleansing of the hair fibers and the modulation of their tribological properties, contrib-uting to the reduction of the negative charge of damaged hair fibers. This is the result of the combined action of the polyelectrolytes and surfactants that play a central role in the effec-tiveness of modern 2-in-1 shampoo formulations. Thus, surfactants contribute to the removal of the dust and fatty compounds during the washing process, whereas polyelectrolytes present a strong ability to be deposited on the surface of damaged fibers, and enhance their tribologi-cal properties. However, the lack of knowledge about the main forces driving the conditioning process has pushed the research and development strategy of the cosmetic industry towards the design of state-of-the-art experimental and theoretical methodologies for evaluating the behavior of mixtures formed by polyelectrolytes and surfactants in solution and adsorbed onto solid surfaces with a negative charge and contact angle for water similar to those appearing in the surface of damaged hair fibers, which have become a very promising tool for obtaining important insights that can be exploited for the optimization of new formulations for hair cleaning and conditioning.

Aims:
This work tries to provide an updated perspective of the current understanding of the behavior of mixtures containing polyelectrolytes and surfactants bearing opposite charges in relation to their performance in hair care and conditioning for providing a link between physi-co-chemical aspects and the performance of real 2-in-1 formulations.

Conclusions:
The study of polyelectrolyte-surfactant mixtures is a powerful tools for obtaining useful information for the optimization of cosmetic formulations for hair care and condition-ing. However, the rational design of this type of cosmetic products must be considered a mul-ti-disciplinary challenge, which requires the combined efforts of researchers with very differ-ent backgrounds.
IL-6, IL-1β, and MDA Correlate with Thrombolysis in Myocardial Infarction
(TIMI) Risk Score in Patients with Acute Coronary Syndrome
Authors: de Paula da Silva Marcus V. , Villar-Delfino Pedro Henrique , Nogueira-Machado José A. , Volpe Caroline M.O. 
Published: February 2022

Background:
Inflammation plays a significant role in the pathophysiology of Acute
Coronary Syndrome (ACS) but is not included in current risk stratification.

Objective:
This study aimed at determining the association between thrombolysis in Myocardial Infarction
(TIMI) risk score and inflammatory biomarkers in the ACS, including unstable angina
(UA), non-ST segment elevation myocardial infarction (NSTEMI), and ST-segment elevation myocardial
infarction (STEMI). We hypothesized that inflammatory biomarkers could add prognostic
value to the TIMI risk score.

Methods:
In this cross-sectional study, serum levels of interleukins (IL)-6 and IL-1β and MDA
(malondialdehyde) were quantified by ELISA and colorimetry, respectively, of patients with ACS
(n = 48; 31.3 % with UA, 33.3 % with NSTEMI, and 35.4 % with STEMI) and healthy controls (n
= 43). We assessed the TIMI scores in the first 24 h after symptom onset.

Results:
The results showed that patients with ACS had significantly higher levels (p<0.05) of the
inflammatory biomarkers IL-6, IL-1β, and MDA than the control group. However, we found no significant
differences in IL-6, IL-1β, and MDA levels among the patients with ACS according to
their classification as UA, NSTEMI, and STEMI. Positive correlations were observed between TIMI
and IL-6 (r=0.68), IL-1β (r= 0.53), and MDA (r=0.58) in patients with UA and between TIMI
and IL-1β (r= 0.62) in STEMI patients.

Conclusion:
These data suggested the presence of a pro-inflammatory profile in patients with ACS
as well as positive correlations between TIMI scores and the inflammatory biomarkers IL-6, IL-1β,
and MDA in patients with UA and between TIMI scores and IL-1β in patients with STEMI. Combining
inflammatory biomarkers with the TIMI risk score could provide better insight into the processes
involved in ACS.

Published: February 2022

Abstract:	The use of information technology cannot be escaped from everyday life in society. In the context of improving the public sector, the government is required to improve performance, responsibility, and public trust and focus more on providing better services by revitalizing public administration by increasing transparency and prioritizing service quality. The Bureau of Personnel uses the “SIMPEG” application in the form of digitizing the public sector which is considered an extraordinary opportunity to create public value. This research is focused on the approach of the SIMPEG pre and post-mobile SSO. The method adopted by this study was mixed methods. The implementation of SIMPEG mobile SSO at the Ministry of Home Affairs has fulfilled the three aspects of the public values ​​stated by Moore, namely legitimacy and support, operational capabilities, and public value. However, based on the findings within the field, some things are still not appropriate. For example, there is still the use of paper-based administration, so that the mobile SSO service has not been optimized. Based on the dimensions of system quality, information quality, and service quality, SIMPEG based on web-based are categorized as quite sustainable, whereas after using SIMPEG mobile SSO application was classified as very sustainable. When viewed from the results of stress and RSQ values, it can be said that the results of the MDS in this study describe a good model and can represent the problems being discussed and conclude that only SIMPEG mobile SSO application is recommended for sustainability.
Developing Reporting Guidelines for Social Media Research (RESOME) by Using a Modified Delphi Method: Protocol for Guideline Development
Authors: Kaushal Aradhna , Bravo Caroline , Duffy Stephen , Lewins Douglas , Möhler Ralph , Raine Rosalind , Vlaev Ivo , Waller Jo , von Wagner Christian 
Published: February 2022

Background
Social media platforms, such as Facebook, Twitter, and Instagram, are being increasingly used to deliver public health interventions. Despite the high level of research interest, there is no consensus or guidance on how to report on social media interventions. Reporting guidelines that incorporate elements from behavior change theories and social media engagement frameworks could foster more robust evaluations that capture outcomes that have an impact on behavior change and engagement.

Objective
The aim of this project is to develop, publish, and promote a list of items for our Reporting Guidelines for Social Media Research (RESOME) checklist.

Methods
RESOME will be developed by using a modified Delphi approach wherein 2 rounds of questionnaires will be sent to experts and stakeholders. The questionnaires will ask them to rate their agreement with a series of statements until a level of consensus is reached. This will be followed by a web-based consensus meeting to finalize the reporting guidelines. After the consensus meeting, the reporting guidelines will be published in the form of a paper outlining the need for the new guidelines and how the guidelines were developed, along with the finalized checklist for reporting. Prior to publication, the guidelines will be piloted to check for understanding and simplify the language used, if necessary.

Results
The first draft of RESOME has been developed. Round 1 of the Delphi survey took place between July and December 2021. Round 2 is due to take place in February 2022, and the web-based consensus meeting will be scheduled for the spring of 2022.

Conclusions
Developing RESOME has the potential to contribute to improved reporting, and such guidelines will make it easier to assess the effectiveness of social media interventions. Future work will be needed to evaluate our guidelines’ usefulness and practicality.

Patient- and Provider-Reported Experiences of a Mobile Novel Digital Therapeutic in People With Opioid Use Disorder (reSET-O): Feasibility and Acceptability Study
Authors: Kawasaki Sarah , Mills-Huffnagle Sara , Aydinoglo Nicole , Maxin Halley , Nunes Edward 
Published: February 2022

Background
Medications for the treatment of opioid use disorder, such as buprenorphine, are effective and essential for addressing the opioid epidemic. However, high dropout rates from medication remain a challenge. Behavioral treatment with contingency management and cognitive behavioral counseling has shown promise for improving the outcomes of buprenorphine treatment but is complicated to deliver. The delivery of behavioral treatment through technology-based platforms has the potential to make it more feasible for widespread dissemination.

Objective
reSET-O is a prescription digital therapeutic and a commercial adaptation of the Therapeutic Education System, an internet-based program with a Community Reinforcement Approach to cognitive behavioral therapy. It delivers cognitive behavioral therapy modules and contingency management rewards upon completion of modules and negative urine drug screens. This pilot study aims to assess the feasibility and acceptability of reSET-O in a community-based opioid treatment program with a Hub and Spoke model of care as part of a larger strategy to maintain individuals in treatment. Objective and qualitative results, as well as acceptability and likeability of reSET-O, were obtained from 15 individuals.

Methods
English-speaking individuals aged ≥18 years with a diagnosis of current opioid use disorder were recruited after being on buprenorphine for at least 1 week of treatment. Two 12-week prescriptions for reSET-O were written for the 24-week study. Patient reports of drug use and likeability scales of reSET-O were conducted at weeks 4, 8, 12, and 24 of the study. Qualitative interviews were also conducted. A total of 4 providers were recruited and provided feedback on the acceptability and feasibility of reSET-O.

Results
Of the 15 participants who participated in this pilot study, 7 (47%) completed 24 weeks, and 8 (53%) were unable to complete because of dropout after enrollment, attrition in treatment, or incarceration. An average of US $96 in contingency management rewards were earned by participants for the completion of modules for the duration of the pilot study. Participants’ subjective feedback revealed that reSET-O was easy to use, enjoyable, and helped provide a safe space to admit recurring substance use.

Conclusions
reSET-O was well accepted based on patient and provider feedback in this pilot study; however, adherence and retention in treatment remain areas for improvement. Randomized control trials are needed to assess whether retention of community-based buprenorphine treatment is enhanced through the use of technology-based behavioral interventions such as reSET-O.

Application of Failure Assessment Diagram (FAD) for Steel Welded Connection Based on BS7910 and DNV-RP-108
Authors: Aboalriha W. 
Published: February 2022

The failure assessment diagram (FAD) method has been widely accepted to evaluate the extent to which cracks may affect structural safety. The usage of this FAD method has been validated and included in [1]-[3]. The structure under investigation, described in four fully welded T-joint (BCC5) specimens, where these welded joints are a source of stress concentration and defects from which fatigue cracks can grow. The four specimens were modeled under different displacement loading using a finite element analysis program Ansys and SolidWorks software. In this work, the application of a FAD (Lr, Kr) using maximum stress, cumulative stress ranges, and the last half-cycle stress range was investigated. The results are showing that all the points were lying outside the FAD curve except for the BCC5D specimen point was inside FAD when using maximum stress.
Conclusions made that the cumulative stress gives Lr and Kr are extremely large and hence predict failure too early. With the Crack Tip Opening Displacement (CTOD) of the test specimen assumed to be about 1mm rather than 0.1mm it was found that, if a FAD is to be used to indicate failure, then both Lr and Kr should be based on the maximum stress. It appears that the FAD methodology does help to predict the final failure (which is the usual application in such cases). This represents more effectively the structural behavior and would be more easily used by designers.
“Not quite the struggle of normatives”: Belonging and entitlement in Swedish “body activism”
Authors: Sveningsson Malin , Vestberg Alva , Hedström Johanna 
Published: February 2022

Abstract
A “body activism” movement, with roots in fat activism and body positivity, has developed in Sweden during the last decade. As new forms of activism emerge, boundaries and approaches are being negotiated. Who is the movement for? Who can engage in it, and how? Through semi-structured interviews, we seek to understand how young Swedes who follow and engage in “body activism” on social media experience and reflect on the activism, belonging and entitlement, and their own participation. The informants discussed activism in terms of inclusiveness and political potential, where the most accessible activism is also the one ascribed with the least political potential. Entitlement is linked to collective identity, where an active participation requires belonging to the marginalised group. This article highlights the significance of boundary work in movements, where too narrowly drawn boundaries can lead to decreased participation and result in an unexploited potential for social change.

Published: February 2022

Abstract

Background
We compared the accuracy of preoperative transvaginal ultrasound (TVUS) versus magnetic resonance imaging (MRI) for the assessment of myometrial invasion (MI) in patients with endometrial cancer (EC), while definitive histopathological diagnosis served as a reference method.

Patients and methods
Study performed at a single tertiary centre from 2019 to 2021, included women with a histopathological proven EC, hospitalized for scheduled surgery. TVUS and MRI were performed prior to surgical staging for assessment MI, which was estimated using two objective TVUS methods (Gordon’s and Karlsson’s) and MRI. Patients were divided into two groups, after surgery and histopathological assessment of MI: superficial (≤ 50%) and deep (> 50%).

Results
Sixty patients were eligible for the study. According to the reference method, there were 34 (56.7%) cases in the study with MI < 50%, and 26 (43.3%) with MI > 50%. Both objective TVUS methods and MRI showed no statistical significant differences in overall diagnostic performance for the preoperative assessment of MI. The concordance coefficient between both TVUS methods, MRI and histopathology was statistically significant (p < 0.001). Gordon’s method calculating MI reached a positive predictive value (PPV) of 83%, negative predictive value (NPV) of 83%, 77% sensitivity, 88% specificity, and 83% overall accuracy. Karlsson’s method reached PPV of 82%, NPV of 79%, 69% sensitivity, 88% specificity, and 80% overall accuracy. Accordingly, MRI calculating MI reached PPV of 83%, NPV of 97%, 97% sensitivity, 85% specificity, and 90% overall accuracy.

Conclusions
We found that objective TVUS assessment of myometrial invasion was performed with a diagnostic accuracy comparable to that of MRI in women with endometrial cancer.
