Subverting geopolitics: The reinvention of geography in post‐revolutionary Mexico
Authors: Vegliò Simone 
Published: December 2022

AbstractWithin the enduring effort to rethink geography from multiple viewpoints and new conceptual categories, critical geographers have recently sought to ‘decentralise geopolitics’ (An, Sharp, and Shaw, 2021, Dialogues in Human Geography, 11(2), 270) by proposing alternative analyses that can tackle the Eurocentric stance that has largely defined the field. This paper contributes to this decentralising effort by bringing to light, historically, an anti‐imperial discourse that took the form of a proper geographical invention. Specifically, the paper analyses the thought of the Mexican intellectual José Vasconcelos – who acted as Secretary of Public Education in the aftermath of the Revolution (1921–1924) – and argues that Vasconcelos' discourse represents a ‘subaltern’ intervention against the imperial presuppositions of the new‐born discipline of geopolitics. The paper contends that Vasconcelos' thought constitutes a conscious attempt, although clearly imbued with ‘postcolonial’ tensions and contradictions, to challenge the ‘scientific’ basis of the emerging geopolitical discourse at that time. By analysing Vasconcelos' geographical and geo‐social imagination through his recuperation of the myth of Atlantis and the idea of Cosmic Race, the paper illuminates an early operation of ‘subaltern geopolitics’ (Sharp, 2011, Geoforum, 42, 271) that aimed to contrast the new wave of Western imperialism which, intensively nurtured by socio‐environmentalist narratives, defined the turn of the twentieth century.

Footprint is a key element in human physiological characteristic study, for determining gender, height and weight. This study is to investigate the reliability of using conventional scanning method by comparing results with motion capture system method. The study takes footprint images from conventional scanning and processed using MATLAB. The captured gait movement data are generated from Vicon Nexus and Vicon Polygon respectively. Afterwards the data from the two methods were analysed for correlation test. The significant difference between measurement of gait parameters using Vicon and conventional scanned method were tested using paired sample t-test and the concurrent validity of conventional scanned method was tested using Pearson correlation. Although there was significance difference between measurement using both methods, the correlation analysis displayed moderate to high positive significant correlation of the parameters indicating the validity of the conventional scanned method. This concludes this study to accept the alternative hypothesis that there is a linear relationship between these two procedures.

Authors: Mat Isa Zaiton , Nazri Mohd Danial , Idris Amidora 
Published: December 2022

This study is concerned with a process known as fumigation in the grain industry. During this process, fumigant is injected at the inlet of storage and is expected to distribute throughout the stored grain to kill the insects in it. The present research focuses on the study of the fumigant (phosphine) flow distribution based on mathematical modelling and numerical simulation through available Computational Fluid Dynamic (CFD) software. In particular, the mathematical modelling is translated into the CFD and simulation is ran to determine areas where insects might find refuge. Hence provide information for conducting more effective fumigation. Numerical simulation using CFD software, for example, FLUENT, is widely known as cost and time effective. However, the numerical simulation needs to be verified before conducting such studies. For a simple case, the analytical solution exists. Therefore, the analytic solution for a simple case, can be used for verification and serve as a basis for adopting a CFD software, FLUENT for an extended geometry and boundary conditions. The numerical results are found to agree well with the analytical results. Overall, the fumigant gas flows towards the outlet regardless of the position of the outlet.
Instrumentation in the Study of Diesel Combustion
Authors: Landen E. W. , Blanc L. A. 
Published: December 2022

Abstract
Physical apparatus and technique have been developed for studying the fundamental processes of combustion within the cylinders of Diesel engines. The study of engine performance actually should begin with the energy changes taking place in the combustible material. For a better understanding of the procedure followed in such tests the authors describe the “window technique” developed for the optical study of combustion. In this system a quartz port is introduced into the cylinder wall through which, for example, a spectrograph may be used to observe the flame. Another method for studying combustion and its effects on the cylinder is by means of the Edgerton camera, or high-speed continuously moving film. The technique of measuring pressures within the combustion chambers with the cathode-ray oscilloscope is described. The most important results of the study reported in this paper are the records of flame duration and pressure obtained.
Improved Hydraulic Presses for Wartime Requirements
Authors: Maude J. H. 
Published: December 2022

Abstract
This paper describes a new rapid-action self-contained hydraulic press developed for wartime industries in Canada. Since this mass-production press employs oil as the pressure medium, the power unit is of special interest. This the author deals with at some length. The operations for which the press is particularly adapted, namely, drawing, indenting, and loading cartridge cases, are described in some detail, as are also the methods of press control. A suitable hydraulagraph was developed for measuring pressure changes, and this instrument provides a permanent graphic record of tests on modern presses. The “one-shot” press and a 300-ton gun-straightening press are also discussed.

Authors: Carswell T. S. , Telfair D. , Haslanger R. U. 
Published: December 2022

Abstract
The results of previous investigations have indicated the influence of temperature on the mechanical properties of molded phenolic compositions, which data are essential if these plastic materials are to be selected properly and designed for structural applications where elevated temperatures are involved either intermittently or continuously. To supplement these data the authors undertook research work to determine the change of impact and flexural strengths with prolonged heating up to 500 hr at temperatures of from 110 to 225 C for six molded phenol-formaldehyde plastics. The compositions studied, the method of testing, and the results in the form of tables and curves, constitute the subject matter of the present paper.
Drying of Textiles
Authors: Walker A. C. 
Published: December 2022

Abstract
In 1937 a textile-drying research project was initiated by the United States Institute for Textile Research and supported by the textile industry, for the purpose of evaluating the effects of temperature and humidity on the physical and chemical properties of important textile fibers. The present paper gives a comprehensive report of the results obtained and points out the basis upon which the industry must proceed in problems relating to textile drying. In all cases, consideration should be given to the theories relating to the form in which the moisture is distributed within the fiber structure and to data of the type discussed by the author.

Published: December 2022

Abstract
Copper is an important material for the nuclear industry; therefore, the correct copper cross section are essential. This paper deals with benchmarking the fast neutron leakage spectrum from a copper block with an intense 252Cf source. The spectrum was measured by the proton recoil method using a stilbene scintillator and spectrometer with pulse shape discrimination. The room effect was subtracted experimentally by shielding cone and confirmed computationally. Simulations were performed using the MCNP6.2 Monte Carlo code. A detailed study on uncertainties has been made. Consequently, as the main source of uncertainties, the measurement apparatus was determined (namely, calibration and number of iterations—up to 15%). From the parameter uncertainty, the most important effects are connected with the mass of cube material—the thickness of the assembly (up to 2%). The effect of copper density uncertainty is low because density was determined experimentally with low uncertainty. The uncertainty related to parameter uncertainties in source structural components is negligible because even neglection of all components leads to a shift in leakage spectra below 7%. Several copper nuclear data libraries were tested as well, and it was found that the calculation with JEFF-3.3 gives the most discrepant results with a discrepancy of up to 60%. The closest results were obtained with ENDF/B-VIII.0 (below 5 MeV, discrepancy within 10%) and JENDL-4.0 (above 5 MeV, discrepancy within 15%). ENDF/B-VII.1 library is relatively close in the region above 5 MeV (discrepancy within 15%), below 5 MeV the agreement is worse (up to 40% discrepancy).

Authors: Parra Barrera Eliana L , Bello Solmara , Gallego-Lopez Gina M , Atero Nicolhole , Reyes Santamaría Elízabeth , Bautista Adriana 
Published: December 2022

IntroductionLeptospirosis is a zoonotic disease with high prevalence in low-income and middle-income countries and tropical and subtropical regions. The clinical symptoms of the disease are similar to symptoms presented by other endemic infectious diseases that could be present simultaneously. Thus, leptospirosis could be masked by similar infections like dengue, malaria, hantavirus, melioidosis and borreliosis, among others. Therefore, leptospirosis could present itself as an under-reported infection or as a coinfection with another pathogen, as has been reported in the literature. However, there is a lack of documented evidence about the specific risk factors of leptospirosis infection, the symptoms, the coinfection’s mortality and the frequency of coinfection. Additionally, leptospirosis coinfections have not been considered a neglected public health concern. Therefore, this systematic review aims to evaluate published articles that show the risk factors associated with leptospirosis infection and coinfection with other pathogens.Methods and analysisThe search process to identify eligible studies will be conducted including the LILACS, ProQuest, PubMed and Scopus databases with no restriction in terms of publication date. Also, grey literature will be included in the research. Authors will independently screen the title and abstracts of the articles identified from the search using Rayyan free software. Eligibility criteria include peer-reviewed research articles written in English or Spanish, including observational studies, cohorts, case–control, cross-sectional, ecological studies and report cases. The systematic review will include studies that report descriptions of leptospirosis cases with coinfection or co-occurrence. The search will be accomplished by articles from 1950 to May 2022. The data will be extracted in a standard extraction form using an Excel format.Ethics and disseminationResults will be published in a peer-reviewed journal. Also, findings will be disseminated through scientific meetings. Ethical approval will not be required as this is a systematic review and primary data will be not collected or included.PROSPERO registration numberCRD42021234754.
Person-centredness in dementia care: study protocol for an integrative review of theoretical approaches
Authors: Purwins Daniel , Serbser-Koal Jonathan , Rommerskirch-Manietta Mike , Roes Martina 
Published: December 2022

IntroductionThe concept of personhood is particularly important in person-centred dementia care because its overall aim is to maintain the personhood of people living with dementia despite disease progression. In a previous review on autonomy for people with dementia, two different underlying concepts of personhood were identified: a rationalistic and a social constructionist concept of personhood. The present integrative review aims to (1) identify existing theoretical approaches in person-centred dementia care, (2) describe the constitutive components for these theoretical approaches, (3) report the goals and/or outcomes to be achieved by person-centred care for people living with dementia and (4) identify the underlying concepts of personhood.Methods and analysisFor our integrative review the search terms were derived from the research questions and clustered according to the ‘PICo’ (Population, Interest, Context) framework. A systematic literature search for theoretical approaches of ‘person-centred dementia care’ will be performed on MEDLINE (via PubMed), CINAHL (via EBSCO) and PsycINFO (via EBSCO). The title/abstract and full-text screening will be performed independently by two researchers according to the inclusion criteria. The data analysis procedure will have two steps: (1) identification and extraction of general information (e.g., type of publication and name of theoretical approaches described) and (2) a qualitative content analysis to analyse the components, goals, outcomes and understanding of the respective underlying conceptions of personhood within the theoretical approaches. The extraction of general information (e.g., authors) will be performed by one researcher and qualitative content analysis will be performed independently by two researchers using MAXQDA software. Any disagreements will be resolved through discussion between the two researchers or, if no consensus can be reached, with all coauthors.Ethics and disseminationDue to the nature of a review, ethical approval is not required. We will disseminate our results in peer-reviewed journals and at (inter)national conferences.

ObjectivesTo assess the performance of the Amb score and Glasgow Admission Prediction Score (GAPS) in identifying acute medical admissions suitable for same day emergency care (SDEC) in a large urban secondary centre.DesignRetrospective assessment of routinely collected data from electronic healthcare records.SettingSingle large urban tertiary care centre.ParticipantsAll unplanned admissions to general medicine on Monday–Friday, episodes starting 08:00–16:59 hours and lasting up to 48 hours, between 1 April 2019 and 9 March 2020.Main outcome measuresSensitivity, specificity, positive and negative predictive value of the Amb score and GAPS in identifying patients discharged within 12 hours of arrival.Results7365 episodes were assessed. 94.6% of episodes had an Amb score suggesting suitability for SDEC. The positive predictive value of the Amb score in identifying those discharged within 12 hours was 54.5% (95% CI 53.3% to 55.8%). The area under the receiver operating characteristic curve (AUROC) for the Amb score was 0.612 (95% CI 0.599 to 0.625).42.4% of episodes had a GAPS suggesting suitability for SDEC. The positive predictive value of the GAPS in identifying those discharged within 12 hours was 50.5% (95% CI 48.4% to 52.7%). The AUROC for the GAPS was 0.606 (95% CI 0.590 to 0.622).41.4% of the population had both an Amb and GAPS score suggestive of suitability for SDEC and 5.7% of the population had both and Amb and GAPS score suggestive of a lack of suitability for SDEC.ConclusionsThe Amb score and GAPS had poor discriminatory ability to identify acute medical admissions suitable for discharge within 12 hours, limiting their utility in selecting patients for assessment within SDEC services within this diverse patient population.
Investigating burn-out contributors and mitigators among intensive care unit nurses during COVID-19: a focus group interview study
Authors: Saravanan Pratima , Masud Faisal , Kash Bita A , Sasangohar Farzan 
Published: December 2022

ObjectivePast literature establishes high prevalence of burn-out among intensive care unit (ICU) nurses, and the influence of the COVID-19 pandemic in intensifying burn-out. However, the specific pandemic-related contributors and practical approaches to address burn-out have not been thoroughly explored. To address this gap, this work focuses on investigating the effect of the COVID-19 pandemic on the burn-out experiences of ICU nurses and identifying practical approaches for burn-out mitigation.DesignSemistructured focus group interviews were conducted via convenience sampling and qualitatively analysed to identify burn-out contributors and mitigators. Maslach Burnout Inventory for Medical Personnel (MBI-MP) and Post-traumatic Stress Disorder Checklist (PCL-5) were employed to quantify the prevalence of burn-out of the participants at the time of study.SettingTwo ICUs designated as COVID-19 ICUs in a large metropolitan tertiary care hospital in the Greater Houston area (Texas, USA).ParticipantsTwenty registered ICU nurses (10 from each unit).ResultsParticipants experienced high emotional exhaustion (MBI-MP mean score 32.35, SD 10.66), moderate depersonalisation (M 9.75, SD 7.10) and moderate personal achievement (M 32.05, SD 7.59) during the pandemic. Ten out of the 20 participants exhibited post-traumatic stress disorder symptoms (PCL-5 score >33). Regarding contributors to burn-out in nurses during the pandemic, five thematic levels emerged—personal, patient related, coworker related, organisational and societal—with each factor comprising several subthemes (eg, emotional detachment from patients, constant need to justify motives to patients’ family, lack of staffing and resources, and politicisation of COVID-19 and vaccination). Participants revealed several practical interventions to help overcome burn-out, ranging from mental health coverage to educating public on the severity of the pandemic and importance of vaccination.ConclusionsBy identifying the contributors to burn-out in ICU nurses at a systems level, the study findings inform the design and implementation of effective interventions to prevent or mitigate pandemic-related burn-out among nurses.
Feasibility of video-based joint hypermobility assessment in individuals with suspected Ehlers-Danlos syndromes/generalised hypermobility spectrum disorders: a single-site observational study protocol
Authors: Mittal Nimish , Sabo Andrea , Deshpande Amol , Clarke Hance , Taati Babak 
Published: December 2022

IntroductionEhlers-Danlos syndromes (EDS)/generalised hypermobility spectrum disorders (G-HSD) affect the connective tissue of the body and present with a heterogeneous set of symptoms that pose a challenge for diagnosis. One of the main diagnostic criteria of EDS/G-HSD is generalised joint hypermobility, which is currently assessed by clinicians during a physical exam. However, the practice for measuring joint hypermobility is inconsistent between clinicians, leading to high inter-rater variability. Often patients are misdiagnosed with EDS/G-HSD based on an incorrect hypermobility assessment, leading to increased referral rates and resource utilisation at specialised EDS clinics that results in unnecessary emotional distress for patients. An objective, validated and scalable method for assessing hypermobility might mitigate these issues and result in improved EDS/G-HSD patient care.Methods and analysisThis study will examine the use of videos obtained using a smartphone camera to assess the range of motion (ROM) and hypermobility of the joints assessed in Beighton score and more (spine, shoulders, elbows, knees, ankles, thumbs and fifth fingers) in individuals with suspected EDS/G-HSD. Short videos of participants will be captured as they undergo a formal assessment of joint hypermobility at the GoodHope EDS Clinic at Toronto General Hospital. Clinicians will measure the ROM at each joint using a clinical-grade goniometer to establish ground truth measurements. Open-source human pose-estimation libraries will be used to extract the locations of key joints from the videos. Deterministic and machine learning systems will be developed and evaluated for estimating the ROM at each joint. Results will be analysed separately for each joint and human pose-estimation library.Ethics and disseminationThis study was approved by the Research Ethics Board of the University Health Network in Toronto on 26 April 2022. Participants will provide written informed consent. Findings from this study will be published in peer-reviewed journals and presented at conferences.Trial registration numberNCT05366114.
