Purpose. Iron metabolism and ferroptosis play crucial roles in the pathogenesis of cancer. In this study, we aim to study the role of ferroptosis-related genes (FRGs) in uterine carcinosarcoma (UCS) and identify potential target for UCS. Methods. Prognostic differentially expressed FRGs were identified of in the TCGA cohort. Integrated analysis, cox regression, and the least absolute shrinkage and selection operator (LASSO) methods of FRGs were performed to construct a multigene signature prognostic model. Moreover, a dataset from Gene Expression Omnibus (GEO) served as an external validation. HSF1 was knockdown in MES-SA and FU-MMT-1 cells, and cell viability, lipid ROS, and intracellular iron level were detected when combined with doxorubicin or gemcitabine. Result. Five FRGs were selected to construct a prognostic model of UCS. The group with high-risk signature score exhibited obviously lower overall survival (OS) than the group with low risk signature score in both TCGA and validated GEO cohorts. Multivariate Cox regression analysis further indicated that the risk score was an independent factor for the prognosis of UCS patients. The high-risk group of UCS has a higher sensitivity in the treatment of doxorubicin and gemcitabine. Knocking down of HSF1 in MES-SA and FU-MMT-1 cells was more sensitive to doxorubicin and gemcitabine via increasing ferroptosis. Conclusions. The five FRGs risk signature prognostic model having a superior and drug sensitivity predictive performance for OS in UCS, and HSF1 is a potential marker sensitive to doxorubicin and gemcitabine in UCS patients.

Authors: Lu Teng , Dang Faqiang , Wang Haitao , Zhao Qingmin , Xu Zhengxiao
Published: January 2022

Nanoparticle-assisted microwave heating of heavy oil has the advantages of fast temperature rise and high thermal efficiency. Compared with traditional heating methods, it can reduce viscosity in a shorter time. In addition, the heavy components in the heavy oil are cracked into light components at high temperatures (this high temperature cannot be reached by conventional heating methods). This process is irreversible and avoids the problem of viscosity recovery of heavy oil after the temperature is reduced. Through absorbing microwave heating experiments, study the effect of nanoparticles on the improvement of the ability of heavy oil to absorb waves and raise temperature; through the heavy oil upgrading experiment and the four-component analysis experiment, the effect of adding hydrogen donor to assist microwave on the viscosity reduction of heavy oil upgrading by nanoparticles was studied, and the problem of viscosity recovery was determined; Through the gravity drainage experiment, the mechanism of nanoparticle-assisted microwave to improve the recovery of heavy oil is studied, and the influence of water content, nanocatalyst, and microwave power on the production of drainage is analyzed. The results show that nanoparticles can improve the wave absorption and heating capacity of heavy oil, and adding 0.6 wt% of nanomagnetic iron oxide catalyst can increase the heating rate of heavy oil in microwave by 60.6%; nanoparticle-assisted microwave heating method can effectively upgrade heavy oil and reduce viscosity. The experimental conditions are 2 wt% tetralin mass concentration, 0.5 wt% nano-Fe3O4 particle mass concentration, microwave heating time 50-60 min, and microwave power 539 W. Under this experimental condition, the viscosity is reduced by 40%. This method has viscosity recovery problems, but final viscosity reduction effect is still very significant. Obtaining the mechanism of nanoparticle-assisted microwave to enhance oil recovery, one of which is that nanoparticles improve the wave absorption and heating capacity of heavy oil and increase the heating speed of heavy oil; the second is that the nanoparticles form local high temperature under the action of microwave, which catalyzes the hydrocracking reaction between the heavy components in the heavy oil and the hydrogen donor, upgrading and reducing the viscosity of the heavy oil, and accelerating the production of heavy oil.

Authors: Alsulami Hemaid
Published: January 2022

The present study aims to examine the relationship of instructors’ emotional intelligence (EI) with the satisfaction index of their corresponding students. For this purpose, data were collected from 650 full-time students and 6 male instructors from a major Middle Eastern University. Emotional intelligence of the instructors was measured with the help of average of students’ responses with the weightage of each assessing parameter, i.e., self-awareness, self-management, social awareness, and relationship management which also reflected the students’ satisfaction index (SSI). Moreover, authenticity of the data was confirmed with the help of Cronbach’s alpha, and the analysis of data was carried out using descriptive statistics, correlation, and box plots. The students’ satisfaction index is calculated by correlating various parameters such as comfort, skill, learning, and motivation in order to identify the most critical parameter. For identifying the most critical parameter, box plots are used. Final results reveal a strong correlation of instructor’s EI with student satisfaction index (r = 0.951,

Published: January 2022

Introduction. Colorectal cancer (CRC), a common digestive tract tumor that contains colon and rectal cancer, is one of the three most common cancers globally. circRNAs are involved in the occurrence and development of CRC, but the mechanism of how they participate in this process remains unclear. Methods. We adopted PCR for expression measure, CCK-8 for cell proliferation detection, Transwell for cell migration and invasion detection, and dual-luciferase reporter assays to detect the potential downstream targets of CCDC66 in CRC. Results. This study showed that circRNA CCDC66 was overexpressed in CRC tissues, and after knockdown, it inhibited the proliferation, migration, and invasion of CRC cells (RKO and HCT-116) in vitro. In addition, the dual-luciferase reporter assay showed that there was a binding site between circCCDC66 and miR-370, as well as between miR-370 and murine double minute 4 (MDM4). That is, circCCDC66 upregulated the expression of MDM4 through competitively binding to miR-370. The expression of circCCDC66 in CRC tissues was positively correlated with MDM4 and negatively correlated with miR-370. Conclusion. In summary, our results indicate that circCCDC66 is a key upregulation of CRC. circCCDC66 upregulates MDM4 through competitive binding to miR-370, thereby enhancing the metastatic ability of CRC cells and promoting the development of CRC.

Authors: Coughlan Rebecca , Moane Siobhan , Larkin Tracey
Published: January 2022

The low saturated fatty acid content of rapeseed oil has resulted in it being classed as one of the most health-benefiting culinary oils. This study determines whether Irish rapeseed oils contain identical fatty acid profiles or whether distinct profiles exist between producers and producers’ successive oil batches. The fatty acid content of Irish rapeseed oils was determined in terms of the desirable MUFA and PUFA and saturated content of these oils. The fatty acid composition demonstrated significant differences in individual unsaturated fatty acid content, while total saturation had insignificant differences. Saturated fatty acid content ranged from 6.10 to 15.8%, while unsaturated fatty acids ranged from 84.20 to 90.10%. Moreover, individual fatty acid content exhibited significant differences (

p
<
0.05

). Oleic acid (C18:1), linoleic acid (C18:2), and stearic acid (C18:0) contents were considered significantly different from other fatty acids detected. The third successive batch from each producer exhibited lower oleic acid content, and the third batch contained higher linoleic acid content, at the same time maintaining a desirable unsaturated fatty acid composition. Studies suggest that differences in the fatty acid composition may be due to cultivation practices such as climate, soil composition, sowing and harvesting, processing techniques, and oxidation reactions.

Published: January 2022

Today, with increasing information technology such as the Internet of Things (IoT) in human life, interconnection and routing protocols need to find optimal solution for safe data transformation with various smart devices. Therefore, it is necessary to provide an enhanced solution to address routing issues with respect to new interconnection methodologies such as the 6LoWPAN protocol. The artificial neural network (ANN) is based on the structure of intelligent systems as a branch of machine interference, has shown magnificent results in previous studies to optimize security-aware routing protocols. In addition, IoT devices generate large amounts of data with variety and accuracy. Therefore, higher performance and better data handling can be achieved when this technology incorporates data for sending and receiving nodes in the environment. Therefore, this study presents a security-aware routing mechanism for IoT technologies. In addition, a comparative analysis of the relationship between previous approaches discusses with quality of service (QoS) factors such as throughput and accuracy for improving routing mechanism. Experimental results show that the use of time-division multiple access (TDMA) method to schedule the sending and receiving of data and the use of the 6LoWPAN protocol when routing the sending and receiving of data can carry out attacks with high accuracy.
A Novel Hypoxic-Angiogenesis-Immune-Related Gene Model for Prognostic and Therapeutic Effect Prediction in Hepatocellular Carcinoma Patients
Authors: Lv Wen , Yao Qi
Published: January 2022

Background. Hepatocellular carcinoma (HCC) is one of the most heterogeneous malignant tumors that have been discovered so far, which makes the prognostic prediction difficult. The hypoxia, angiogenesis, and immunity-related genes (HAIRGs) are closely related to the development of liver cancer. However, the prognostic and treatment effect of hypoxia, angiogenesis, and immunity-related genes in HCC continues to be further clarified. Methods. The gene expression quantification data and clinical information in patients with liver cancer were downloaded from the TCGA database, and HAIRG signature was built by using the least absolute shrinkage and selection operator (LASSO) technique. Patient from the ICGC database validated the model. Then, tumor immune dysfunction and exclusion (TIDE) algorithm was applied to estimate the clinical response to immunotherapy and the sensitivity of drugs was evaluated by the half-maximal inhibitory concentration (IC50). Result. The HAIRGs were identified between the HCC patients and normal patients in the TCGA database. In univariate Cox regression analysis, seventeen differentially expressed genes (DEGs) were associated with overall survival (OS). An eight HAIRG signature model was constructed and was used to divide the patients into two groups according to the median value of the risk score base on the TCGA dataset. Patients in the high-risk group had a significant reduction in OS compared to those in the low-risk group (

P
<
0.001

in the TCGA,

P
<
0.001

in the ICGC). For TCGA and ICGC databases of univariate Cox regression analyses, the risk score was used as an independent predictor of OS (

HR
>
1

,

P
<
0.001

). Functional analysis showed that the relevant immune pathways and immune responses were enriched, cellular component analysis showed that the immunoglobulin complex and other related substances were enriched, and immune status existed a difference in the high- and low-risk groups. Then, the tumor immune dysfunction and exclusion (TIDE) algorithm presented differences in immune response in the high- and low-risk groups (

P
<
0.05

), and based on drug sensitivity prediction, patients in the high-risk group were more sensitive to cisplatin compared to those in the low-risk group in both the TCGA and ICGC cohorts (

P
<

). Conclusions. HAIRG signature can be utilized for prognostic prediction in HCC, while it can be considered a prediction model for clinical evaluation of immunotherapy response and chemotherapy sensitivity in HCC.

Published: January 2022

Bambara groundnut (Vigna subterranea L. Verdc.) is an un­derutilized minor legume crop with climate resilience and great potential use in world agriculture. This study aimed to cytogenetically characterize the genome and chromosome properties of Bambara groundnut. We cloned, sequenced, and mapped a 50-bp centromere-specific tandem repeat on all chromosomes. In addition, a 400-bp subtelomeric repeat was discovered and mapped on a single pair of chromosomes. A Bambara groundnut karyotype was constructed using these novel repeats along with ribosomal RNA genes (45S and 5S) and telomeric DNA sequences. This study provides the first analysis of the genome and chromosome properties of Bambara groundnut. We discuss our findings in relation to genetic improvement of Bambara groundnut and centromere evolution in legume species.

Recicladores de base na América Latina
Authors: Izidoro Leila Giovana
Published: January 2022

A partir da década de 1970, organismos financeiros internacionais passaram a promover a implementação do modelo de gestão integrada de resíduos sólidos na América Latina, visando a exploração de recursos energéticos em aterros sanitários e a comercialização de recicláveis. Os recicladores de base, trabalhadores que sobrevivem da coleta, triagem e venda de materiais recuperados, foram impactados por essas iniciativas, por meio de sua expulsão dos lixões a céu aberto, da criminalização da sua presença nas ruas da cidade e da paulatina regulamentação do seu trabalho. O objetivo deste artigo é identificar esses impactos na conformação da força de trabalho dos recicladores em um estudo de caso comparado entre as cidades de São Paulo e Cidade do México. Foram utilizadas como fontes de pesquisa a revisão de literatura, entrevistas semiestruturadas e trabalho de campo realizado entre 2019 e 2021 em ambas as cidades. A partir dos dados mobilizados, concluiu-se que, a despeito dos diferentes processos de inserção dos recicladores na gestão de resíduos sólidos, em ambas as cidades a exploração de sua força de trabalho tem se realizado da forma mais benéfica para o capital, em redes de subcontratação conformadas pelo Estado, em parceria com empresas.
Physician Approaches to Imaging and Revascularization for Acutely Symptomatic Carotid Stenosis: Insights from the Hot Carotid Qualitative Study

Background

Evidence informing the choice between carotid endarterectomy and carotid artery stenting for acutely symptomatic carotid stenosis (“hot carotid”) is dated and does not factor in contemporary therapies or techniques. The optimal imaging modality is also uncertain. We explored the attitudes of stroke physicians regarding imaging and revascularization of patients with acute symptomatic carotid stenosis.

Methods

We used a qualitative descriptive methodology to examine decision‐making approaches and opinions of physicians regarding the choice of imaging and revascularization procedures for hot carotids. We conducted semistructured interviews with purposive sampling of 22 stroke physicians from 16 centers in 6 world regions and various specialties: 11 neurologists, 3 geriatricians, 5 interventional neuroradiologists, and 3 neurovascular surgeons.

Results

Qualitative analysis revealed several themes regarding clinical decision‐making for hot carotids. Whereas CT angiography was favored by most participants, timely imaging availability, breadth of information gained, and surgeon/interventionalist preferences were important themes influencing the choice of imaging modality. Carotid endarterectomy was generally favored over carotid artery stenting, but participants’ choice of intervention was influenced by healthcare system factors such as use of multidisciplinary vascular teams and operating room or angiography suite availability, and patient factors like age and infarct size. Areas of uncertainty included choice of imaging modality for borderline stenosis, utility of carotid plaque imaging, timing of revascularization, and the role of intervention with borderline stenosis or intraluminal thrombus.

Conclusions

This qualitative study highlights practice patterns common in different centers around the world, such as the general preference for CT angiography imaging and carotid endarterectomy over carotid artery stenting but also identified important differences in availability, selection, and timing of imaging and revascularization options. To gain widespread support, future carotid trials will need to accommodate identified variations in practice patterns and address areas of uncertainty, such as optimal timing of revascularization with modern best medical management and risk‐stratification with imaging features other than just degree of stenosis.

Published: January 2022

Background

Extended thrombolysis in cerebral infarction (eTICI) 2c/3 reperfusion after mechanical thrombectomy (MT) is associated with better stroke outcomes than eTICI 2b. Whether additional MT attempt after achieving eTICI 2b (beyond 2b attempt) leads to better outcomes is unknown.

Methods

Consecutive patients with acute anterior circulation stroke who achieved eTICI 2b during MT were divided into 2 groups: those who further tried MT (beyond‐2b group) and those without (nonbeyond‐2b group). The patients who directly achieved eTICI 2c/3 without experiencing 2b (direct‐2c/3 group) were also studied. The outcomes included the reperfusion status, favorable outcome (3‐month modified Rankin scale score of 0–2), neurological improvement (a ≥10‐point decrease of the National Institutes of Health Stroke Scale score from baseline or the score of 0) at 24 hours and symptomatic intracranial hemorrhage.

Results

Of 308 patients, 50 were in the beyond‐2b group, 87 in the nonbeyond‐2b group, and the remaining 171 in the direct‐2c/3 group. Perfusion of middle cerebral artery branches supplying the primary motor cortex was worse in the beyond‐2b than the nonbeyond‐2b group at the time of eTICI 2b (
P
=0.007). Favorable outcome was similarly common (48% for each,
P
=0.40). Neurological improvement was more frequent (52% versus 37%;
P
=0.04) and symptomatic intracranial hemorrhage tended to be more common (6% versus 1%,
P
=0.11) in the beyond‐2b than the nonbeyond‐2b group. Eighteen patients (36%) in the beyond‐2b group finally achieved eTICI 2c/3; 10 of these (56%) and 14 of the remaining 32 (44%) had favorable outcome (
P
=0.83). The former rate was similar to that in the direct‐2c/3 group (58%;
P
=0.99).

Conclusions

Patients undergoing additional MT attempt after achieving eTICI 2b had numerically but not significantly more symptomatic intracranial hemorrhage and showed a similar level of functional outcome at 3 months than those who did not. When eTICI 2c/3 was finally achieved by additional attempts, functional outcome was similar with that of patients who directly achieved eTICI 2c/3 without experiencing 2b.

An application of neighbourhoods in digraphs to the classification of binary dynamics
Authors: Conceição Pedro , Govc Dejan , Lazovskis Jānis , Levi Ran , Riihimäki Henri , Smith Jason P.
Published: January 2022

A binary state on a graph means an assignment of binary values to its vertices. A time-dependent sequence of binary states is referred to as binary dynamics. We describe a method for the classification of binary dynamics of digraphs, using particular choices of closed neighbourhoods. Our motivation and application comes from neuroscience, where a directed graph is an abstraction of neurons and their connections, and where the simplification of large amounts of data is key to any computation. We present a topological/graph theoretic method for extracting information out of binary dynamics on a graph, based on a selection of a relatively small number of vertices and their neighbourhoods. We consider existing and introduce new real-valued functions on closed neighbourhoods, comparing them by their ability to accurately classify different binary dynamics. We describe a classification algorithm that uses two parameters and sets up a machine learning pipeline. We demonstrate the effectiveness of the method on simulated activity on a digital reconstruction of cortical tissue of a rat, and on a nonbiological random graph with similar density.
The prevalence and impact of university affiliation discrepancies between four bibliographic databases—Scopus, Web of Science, Dimensions, and Microsoft Academic
Authors: Purnell Philip J.
Published: January 2022

Research managers benchmarking universities against international peers face the problem of affiliation disambiguation. Different databases have taken separate approaches to this problem and discrepancies exist between them. Bibliometric data sources typically conduct a disambiguation process that unifies variant institutional names and those of its subunits so that researchers can then search all records from that institution using a single unified name. This study examined affiliation discrepancies between Scopus, Web of Science (WoS), Dimensions, and Microsoft Academic for 18 Arab universities over a 5-year period. We confirmed that digital object identifiers (DOIs) are suitable for extracting comparable scholarly material across databases and quantified the affiliation discrepancies between them. A substantial share of records assigned to the selected universities in any one database were not assigned to the same university in another. The share of discrepancy was higher in the larger databases (Dimensions and Microsoft Academic). The smaller, more selective databases (Scopus and especially WoS) tended to agree to a greater degree with affiliations in the other databases. Manual examination of affiliation discrepancies showed that they were caused by a mixture of missing affiliations, unification differences, and assignation of records to the wrong institution.
Covid-19 refereeing duration and impact in major medical journals
Authors: Kousha Kayvan , Thelwall Mike
Published: January 2022

Two partly conflicting academic pressures from the seriousness of the Covid-19 pandemic are the need for faster peer review of Covid-19 health-related research and greater scrutiny of its findings. This paper investigates whether decreases in peer review durations for Covid-19 articles were universal across 97 major medical journals, as well as Nature, Science, and Cell. The results suggest that on average, Covid-19 articles submitted during 2020 were reviewed 1.7–2.1 times faster than non-Covid-19 articles submitted during 2017–2020. Nevertheless, while the review speed of Covid-19 research was particularly fast during the first 5 months (1.9–3.4 times faster) of the pandemic (January–May 2020), this speed advantage was no longer evident for articles submitted in November–December 2020. Faster peer review was also associated with higher citation impact for Covid-19 articles in the same journals, suggesting it did not usually compromise the scholarly impact of important Covid-19 research. Overall, then, it seems that core medical and general journals responded quickly but carefully to the pandemic, although the situation returned closer to normal within a year.
Recent Research in Syriac Studies and the Recurring Question of Identity
Authors: Durmaz Reyhan
Published: January 2022

Identity Puzzles, Identity and Christian-Muslim Interaction, Redefining Christian Identity … These titles are only three examples of a growing corpus of scholarship that asks the question, “How did Syriac-speaking Christians in the Near East perceive and present their communities?” Some scholars approach this question from the angle of theological distinctions between Syriac Christian groups, while others look into the power structures and discursive negotiations between Christian and other communities in the Near East. As our understanding of Syriac communities in the pre-modern Near East is further nuanced, contemporary religious and national identities shape the scholarship in new ways. This article summarizes the major theories brought to bear on the study of “Syriac identity” in premodern and modern era in the past twenty years. By mapping the field, I aim to demonstrate how the academic study of identity in Syriac communities have been underpinned by the question of the so-called East-West divide.
Colonial Modernity and Diffusion of Power: Identity and Community Formation among Mappilas of Malabar
Authors: T.A Shameer
Published: January 2022

This paper explores colonial modernity and the knowledge system’s role in constituting community formation among the Mappilas of Malabar. Colonial modernity, such as the introduction of printing, made this transformation more advanced and communitarian in structure. It also discusses colonialism as a force to reshape and bring socio-cultural changes in Malabar during the time. It argues that the existence of a clearly defined community is not a predetermined social fact; it looks at how the Mappilas were represented in an analytical category. In Malabar, the press and literature have played an essential role in framing community consciousness among Mappila society. Print media has brought a revolution in the transmission of knowledge. This paper will encompass the coming of the printing press and the moulding of community consciousness among the Mappilas of Malabar. It discusses the discursive and non-discursive practices of the colonial state for constructing various identities in Malabar.

Preparation of ZrO2 in SiC coating via hydrothermal method and sintering process onto carbon/carbon composite
Authors: Mao Zu-Li , Yang Li , Wu Jie
Published: January 2022

To reduce the defects in SiC coating, a SiC/ZrO2 composite is prepared and coated onto carbon/carbon composite via hydrothermal method and sintering process. The microstructure, surface morphology, chemical states, and elemental distribution of SiC/ZrO2 coating
are analysed with X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and X-ray photoelectron spectroscopy (XPS). In addition, we analyze the tribological behavior of the SiC and SiC/SiC/ZrO2 coatings and the related microstructure.
The results show that SiC/ZrO2 coating is composed of SiC phase, ZrO2 phase, carbon phase, and SiO2 phase. EDS results show that Si, C, O, and Zr elements are present in the SiC/ZrO2 coating. Moreover, XPS results show the presence of SiC, ZrO2,
and SiO2. According to the SEM image, the coating is dense except for some observable cracks. Notably, specimens with the SiC/ZrO2 coating have smaller, more stable friction coefficients and less weight loss than specimens with the SiC-only coating. The formation of ZrO2
strengthens the SiC coating, while the SiO2 formed in the coating acts as a lubricant and reduces the friction coefficient of the coating.
Observation on the effect of high-quality nursing intervention in gadolinium-based sodium material adjuvant radiotherapy for non-small cell lung cancer
Authors: Zhang Lina , Xing Yanan , Zhu Li , Han Xiang
Published: January 2022

Non-small cell lung cancer (NSCLC) is a common malignant tumor. Because of the concealment of its early clinical symptoms, most of the patients are diagnosed at the middle and advanced stages. Nowadays, the NSCLC has become one of the critical factors affecting the quality of life of
Chinese residents. Traditional radiotherapy cannot meet the clinical treatment needs of NSCLC patients. Here, we used gadolinium oxide (Gd2O3) as a new radiosensitizer matrix and introduced paclitaxel (PTX), with excellent anticancer cell migration function to construct
paclitaxel-gadolinium oxide nanoparticles (PTX-Gd2O3 NPs). The clinical experiments show the unique nanometer radiation dose enhancement effect and radiosensitive function of PTX-Gd2O3 NPs. The new nanodrug can successfully exert the secretion of
thrombin-sensitive protein-1 of PTX, thereby inhibiting the proliferation and migration of tumor cells, which is expected to provide a new direction for treating long-term NSCLC.

In this research, the diamond particles were coated with titanium by microwave heating method, then the Ti-coated diamond particles were used as raw material to fabricate the diamond/Al composites by microwave sintering. The result shows that the diamond particles could be covered with
a uniform and continuous Ti coating under microwave irradiation, and the best Ti coating was obtained at 810 °C for 1 h. The metallic bond between diamond and Ti was formed to generate the intermediate transition layer of TiC. The diamond/Al composites which used Ti-coated diamond particles
as raw material and were fabricated by microwave sintering show high relative density and hardness. The relative density and hardness of the diamond/Al composites increased with the temperature. While the composites were sintered at 710 °C for 1 h, the density could reach 2.855 g·cm−3,
and relative density was 92.09%, which shows better microstructures and properties. There is Al3Ti alloy phase in Ti-coated diamond/Al composites, so the Ti-coated diamond can be well combined with the Al matrix, which can further improve the properties of the composites.

Nanotechnology has the potential to have a huge effect on all industries, including the oil and gas industry. Virtual Reality (VR) also has large and comprehensive perspective in the interest of oil and gas industry. VR approach becomes essential at different phases in oil and gas industry.
This study aims to identify the causes of Thermoelectric Generator (TEG) defect in oil and gas industry. This work also develops VR training platform with nano-display devices. The training platform is to be used in the oil and gas industry for heat pipe removal and pipeline construction.
Implementation of VR training platform offers huge advantage to the industry as it does not interrupt the operation and does not require investment in the training facilities. Case study was used to determine the causes of TEG defects. Continuous exposure to heat, over production and prolonged
run are the three factors that were found to be the defect of Thermoelectric Generator (TEG) in oil and gas industry. Unity 3D, HTC™ Vive device, Autodesk Maya software and C# Programming were used to develop the VR platform. Finally, the 3D models of TEGs were designed and modelled
for heat pipe removal and pipeline installation in oil and gas industry. As we understand that nanotechnology plays an integral role in hardware and communications for virtual reality technology, one might propose nano-display which provides the best resolution and pixels smaller than a micrometer.

Published: January 2022

Alcohols are increasingly being looked upon as the most viable alternative to the conventional sources of energy. Methanol is the first member of the alcohol family and can be easily synthesized from syngas. It is an attractive blend to gasoline due to its advantageous properties. There is a necessity to make sure that the infrastructure is ready to adapt these alternative fuels. Hence, the aim of this study is to assess the degradation of widely used thermoplastics in fuel tanks, pipes, and the fuel injection system, namely, polytetrafluoroethylene (PTFE), polyethyleneterephthalate (PET), and high density polyethylene (HDPE) post exposure to methanol–gasoline blends (P100, M15, and M30) for a period of 4, 10, and 30 days. The effects of the exposure were examined by comparing changes in gain/loss of mass, hardness, elongation, and tensile strength. The surface morphology changes of the polymeric coupons were characterized by scanning electron microscopy and their elemental analysis was done by energy dispersive X-ray spectroscopy. The studied materials were found to gain mass in the order HDPE > PTFE >PET. The decrease in hardness was found to be more in HDPE followed by PTFE and PET. PTFE and PET showed reduction in strength but an increase in tensile strength was observed for HDPE post exposure to fuel blend. Highest change in elongation was found in HDPE followed by PTFE and PET. The changes were found to be the least in P100 followed by M15 and maximum in M30 blends for all immersion periods.
Transfer or Translation? Rethinking Traveling Technologies from the Global South
Authors: Lu Miao , Qiu Jack Linchuan
Published: January 2022

Technology flows are becoming increasingly diverse in the twenty-first century, calling for an update of concepts and frameworks. Reflecting on the inherent tensions of technology transfer, including its technocratic dreams, insensitivity to technological materiality, and narrow focus on certain human actors, we propose technology translation as a complementary conceptual framework to understand traveling technologies. Taking a socio-technical approach, technology translation views artifacts as socially shaped with distributed agency, which makes technology flows unstable and unpredictable. In so doing, we develop a typology to explain five technology flow scenarios, shedding new light on the mechanisms of technology traveling by foregrounding the role of translators. Last, we discuss the politics of translation and elaborate how technology translation opens new space to engage with the complexity and uncertainty of technology flows, especially in the Global South.
Do We Still Need Professional Boundaries? The multiple influences of boundaries on interprofessional collaboration
Authors: Farchi Tomas , Dopson Sue , Ferlie Ewan
Published: January 2022

Although a body of research suggests that interprofessional collaboration is hindered by the presence of professional boundaries, more recent work has demonstrated that removing these boundaries also has negative consequences for collaboration. To address these paradoxical findings, we examine two different team-level initiatives that aimed at softening and breaking down professional boundaries, drawing on data gathered from 78 in-depth interviews and two years of observations of four cross-occupational teams in the English National Health Service. Our inductive analysis of this data shows that professionals use boundaries and their manifestations – which become apparent through materialization, articulation and embodiment – to identify and retrieve professional categories. The conspicuous presence of boundaries allows professionals to anticipate other team members’ expertise and roles, as well as different aspects of team tasks. We theorize our findings by showing how professional boundaries can be positively interlaced with interprofessional collaboration by making visible and grounding naturalized systems of classification.
The Naturalization of Mexican Immigrants in the United States
Authors: Grebler Leo
Published: January 2022

L'auteur évalue et analyse le taux de naturalisation des immigrés légaux, en provenance du Mexique, en comparaison avec tous les immigrés aux Etats-Unis; et il interprète les conclusions comme indicateurs de la relation entre la minorité Mexico-Américaine et la société dominante. Faisant grand usage des données statistiques à disposition, il montre le taux extrêmement bas de naturalisation parmi les immigrés mexicains dans la période 1959–1965. L. Grebler interprète ce phénomène dans le contexte d'un vaste rayon d'interactions entre la population Mexico-Americaine et prouve le taux minime de naturalisation par rapport: — au système traditionnel d'isolation de la minorité d'avec la société dominante; — aux efforts des Consuls mexicains de garder l'identification des immigrés avec le pays d'origine; — à la relation de crainte et de méfiance envers les autorités gouvernementales; — aux intentions d'une émigration provisoire; — au manque général d'instruction et aux conditions économiquement faibles des immigrés mexicains.
Puerto Ricans in Perspective: The Meaning of Migration to the Mainland
Authors: Fitzpatrick Joseph P.
Published: January 2022

This article will first examine the unique characteristics of the Puerto Rican migration; secondly, it will study the process of assimilation particularly in relation to the search for identity which presents a number of special problems to the Puerto Ricans. It will analyze one of the special problems of identity which consists in a shift from an emphasis on culture to an emphasis on power as the basis for the establishment of a strong Puerto Rican community. Finally it will seek to interpret the experience of the Puerto Ricans as part of the human effort and suffering inevitably involved in the continuing creative achievement of New York City. In the historical perspective of the past migrations to the City it is reasonable to be optimistic about the present one.

To strengthen this optimistic view, the creative, mobile elements among the Puerto Ricans must assume a greater role in the institutional structures and decision making processes of the mainland.

Published: January 2022

Background:

No comparative studies have evaluated anatomic risk factors in a large cohort including both patients with anterior cruciate ligament (ACL) ruptures and healthy participants.

Purpose:

To determine which anatomic parameters are independently associated with an ACL rupture and the diagnostic values of the individual and combined anatomic parameters.

Study Design:

Case-control study; Level of evidence, 3.

Methods:

A total of 352 male patients who underwent arthroscopic ACL reconstruction because of a primary ACL rupture and 350 age-, sex-, body mass index–, and side dominance–matched healthy participants were included. Measurements of 32 previously determined parameters and 7 calculations were performed. Between-group differences were calculated. Univariate and multivariate logistic regression models and receiver operating characteristic curve analysis were conducted for the individual and combined independently associated factors.

Results:

The mean age and body mass index of all participants were 29.9 ± 7.7 years and 27.2 ± 3.1, respectively. There were significant differences between the groups regarding the notch width (NW), notch shape index, anterior tibial slope, notch width index, NW–eminence width (NW:EW) ratio, notch height, axial lateral wall angle, medial intercondylar ridge thickness, alpha angle, medial tibial depth (MTD), lateral tibial slope (LTS), coronal tibial plateau width, eminence width index, tibial proximal anteroposterior distance (TPAP), lateral condylar anteroposterior distance (LCAP)/TPAP, ACL cross-sectional area, ACL volume, medial and lateral meniscal cartilage height, medial and lateral meniscal cartilage angle (MCA), and medial and lateral meniscal cartilage bone height. The NW:EW ratio (odds ratio [OR], 4.419; P = .017), MTD (OR, 8.617; P = .001), LTS (OR, 2.254; P = .011), LCAP/TPAP (OR, 2.782; P = .037), and medial MCA (OR, 1.318; P = .010) were independently associated with the development of an ACL rupture. Combining the independently associated factors revealed a sensitivity of 93% and a specificity of 94% (area under the curve, 0.968).

Conclusion:

Patients with ACL ruptures could be distinguished from uninjured controls with high sensitivity and specificity via the combined use of the NW:EW ratio, MTD, LTS, LCAP/TPAP, and medial MCA. In clinical practice, these findings may contribute to the development of preventive strategies for ACL ruptures.
