Porous Microspheres Comprising CoSe2 Nanorods Coated with N-Doped Graphitic C and Polydopamine-Derived C as Anodes for Long-Lived Na-Ion Batteries
Authors: Lee Jae Seob , Saroha Rakesh , Cho Jung Sang 
Published: April 2022

AbstractMetal–organic framework-templated nitrogen-doped graphitic carbon (NGC) and polydopamine-derived carbon (PDA-derived C)-double coated one-dimensional CoSe2 nanorods supported highly porous three-dimensional microspheres are introduced as anodes for excellent Na-ion batteries, particularly with long-lived cycle under carbonate-based electrolyte system. The microspheres uniformly composed of ZIF-67 polyhedrons and polystyrene nanobeads (ϕ = 40 nm) are synthesized using the facile spray pyrolysis technique, followed by the selenization process (P-CoSe2@NGC NR). Further, the PDA-derived C-coated microspheres are obtained using a solution-based coating approach and the subsequent carbonization process (P-CoSe2@PDA-C NR). The rational synthesis approach benefited from the synergistic effects of dual carbon coating, resulting in a highly conductive and porous nanostructure that could facilitate rapid diffusion of charge species along with efficient electrolyte infiltration and effectively channelize the volume stress. Consequently, the prepared nanostructure exhibits extraordinary electrochemical performance, particularly the ultra-long cycle life stability. For instance, the advanced anode has a discharge capacity of 291 (1000th cycle, average capacity decay of 0.017%) and 142 mAh g−1 (5000th cycle, average capacity decay of 0.011%) at a current density of 0.5 and 2.0 A g−1, respectively.
Co-offending and Criminal Careers in Organized Crime
Authors: Meneghini Cecilia , Calderoni Francesco 
Published: April 2022

AbstractThe growing research on co-offending over the life course is based on relatively small, general offending samples, followed for a short period, and from a limited set of countries. This study expands current knowledge by examining the relation of co-offending with age, criminal experience, crime type, and crime seriousness in a large sample of Italian serious organized crime offenders with criminal careers spanning between age 14 and late adulthood. The sample includes 160,262 offenses by 10,530 Italian mafia offenders. After preliminary descriptive statistics, random-effects logistic regressions estimate how age, criminal experience, crime type, and seriousness are independently related to the co-offending probability. Co-offending decreases only moderately with both the age and criminal experience of organized crime offenders, while more prolific offenders exhibit a stable co-offending prevalence as their experience increases. Co-offending varies significantly by crime type, and it is more frequent for more serious offenses. In line with previous research, co-offending has a relevant functional component even for organized crime offenders: results suggest it is instrumental to perpetrating specific offense types and more serious offenses. However, results also show that specific social and criminal contexts promote co-offending among older and more experienced offenders.

AbstractMesoporous silica nanoparticles (MSNs) can promote the solubility and absorption of pesticides by plants and are widely used as a delivery system to improve the efficacy of pesticide applications. In this study, MSNs with 20 nm particle size were produced. Additionally, a water-soluble chitosan (CS) derivative, here called N-(2-Hydroxyl) propyl-3- tri-methyl-ammonium CS chloride (HTCC) was produced and used to cap the outer surface of the MSNs preloaded with the pesticide fludioxonil (Flu). The HTCC coating layers resulted in a pesticide loading efficiency of 84% on the MSNs in comparison to a loading efficiency of 20% of uncoated particles. A comparative in vitro analysis indicated that Flu@MSNs20nm-HTCC loaded with a 0.05 mg/L dose of fungicide had significant higher fungicidal activity than the same fungicide at 1 mg/L dose against F. oxysporum f. sp. radicis-lycopersici (FORL). Moreover, after an initial burst, MSNs20nm-HTCC kept releasing Flu for 21 d, compared to an activity of 7 d associated with the direct release of Flu. Greenhouse data showed that 0.1 mg/L Flu applied through MSNs20nm-HTCC is sufficient to reduce Fusarium crown and root rot disease severity to a value of less than 6% in tomato plants, without any noticeable phytotoxicity after 70 d. In comparison, 1.56 mL/L of the fungicide are required to reach a 27% disease severity level. Thus, we suggest that HTCC-decorated MSNs20nm has a great potential as a nanodelivery systems for agrochemical applications. We also suggest that this work contributes to the notion that agro-nanotechnology is a powerful, environmentally-safe and cost-effective approach for a sustainable and long term protection of plants from disease.
Investigation of the material separation behaviour of rocks using scratch tests for the design of tool grinding processes
Authors: Denkena Berend , Breidenstein Bernd , Bergmann Benjamin , Wolters Philipp 
Published: April 2022

AbstractThe use of natural rocks as cutting tool material poses an environmentally friendly alternative to conventional cutting tool materials. So far, however, the basics of tool grinding processes for rock tools have not been systematically investigated. This study, therefore, presents an investigation of the material removal mechanisms of four different types of rocks and a mono mineral via scratch tests analogous to a face plunge grinding process used in tool grinding. The aim is to contribute to a knowledge-based design of tool grinding processes for rock tools. This also includes a characterization of their mechanical properties. The occurring material removal mechanisms identified by SEM-images as well as width and depth of the scratches are used to evaluate the influence of single grain chip thickness and cutting speed on material removal mechanisms. The results show that ductile material removal is possible for all rocks in certain areas of single grain chip thicknesses ranging from 0.28 µm to 3.75 µm depending on the rock used and the applied cutting speed. Besides this, the results show optima for ductile material removal at single grain chip thicknesses that are up to 87-times higher than predicted by an analytical model. Additionally, recommendations for the design of the tool grinding process of the investigated rocks based on the obtained results are presented.
Digital subtraction angiography-guided ethanol sclerotherapy for peripheral venous malformation: A retrospective cohort study of single centre experience
Authors: Cuong Lam Thao , Bang Ho Tat , Vy Tran Thanh , Tien Tran Quyet 
Published: April 2022

ABSTRACT

Introduction:
Venous malformations are the most common type of vascular malformations. Ethanol sclerotherapy is one of the most commonly used treatment methods. This study is to evaluate the initial results of digital subtraction angiography-guided ethanol sclerotherapy in patients with peripheral venous malformation.

Methods:
This was a retrospective cohort study of a single centre experience. Patients diagnosed with peripheral venous malformation who underwent digital subtraction angiography-guided ethanol sclerotherapy from Jan 2017 to Jun 2021 were included in the study. Medical records were reviewed to record demographic information, lesion characteristics including clinical and magnetic resonance imaging findings, treatment sessions, therapeutic outcomes, and complications.

Results:
A total of 104 patients were included. The mean number of procedures was 2.0 ± 1.3 times. Last follow-ups revealed a partial relief of symptoms in 97.2% of patients, and three patient (2.9%) showed no improvement. Post-treatment imaging revealed an overall objective response rate of 93.3%. Early post-procedural minor complications occurred after sclerotherapies in 31.7% of patients and were entirely resolved by conservative means. On multivariate analysis, poorly-defined margin (OR: 10.7, 95% CI: 2.28–76.9) and volume of venous malformation on MRI (OR: 1.04, 95% CI: 1.00–1.11) were independent predictors of “no-good response” to percutaneous ethanol sclerotherapy.

Conclusion:
Percutaneous sclerotherapy is safe and effective in the treatment of venous malformation. A poor-defined margin and volume of VMs on MRI were statistically significant predictors of the initial percutaneous ethanol sclerotherapy results and may be useful in selecting patients.

ABSTRACT:Introduction:Delayed cerebral ischemia (DCI) is a complication of aneurysmal subarachnoid hemorrhage (aSAH) and is associated with significant morbidity and mortality. There is little high-quality evidence available to guide the management of DCI. The Canadian Neurosurgery Research Collaborative (CNRC) is comprised of resident physicians who are positioned to capture national, multi-site data. The objective of this study was to evaluate practice patterns of Canadian physicians regarding the management of aSAH and DCI.Methods:We performed a cross-sectional survey of Canadian neurosurgeons, intensivists, and neurologists who manage aSAH. A 19-question electronic survey (Survey Monkey) was developed and validated by the CNRC following a DCI-related literature review (PubMed, Embase). The survey was distributed to members of the Canadian Neurosurgical Society and to Canadian members of the Neurocritical Care Society. Responses were analyzed using quantitative and qualitative methods.Results:The response rate was 129/340 (38%). Agreement among respondents was limited to the need for intensive care unit admission, use of clinical and radiographic monitoring, and prophylaxis for the prevention of DCI. Several inconsistencies were identified. Indications for starting hyperdynamic therapy varied. There was discrepancy in the proportion of patients who felt to require IV milrinone, IA vasodilators, or physical angioplasty for treatment of DCI. Most respondents reported their facility does not utilize a standardized definition for DCI.Conclusion:DCI is an important clinical entity for which no homogeneity and standardization exists in management among Canadian practitioners. The CNRC calls for the development of national standards in the definition, identification, and treatment of DCI.

January 1993: The Founding of Education International
Authors: Smaller Harry 
Published: April 2022

AbstractSince the late nineteenth century, teachers have come together to found associations and unions in Europe and beyond. Drawing on oral histories, primary and secondary documents, and media reports, this paper delves into this rich historical background, leading to the founding of Education International in 1993. In particular it explores the relationships and tensions within and between these predecessor organizations, as well as the ways in which they interacted with the larger political forces of their times. Education International is now a significant organization, representing teachers and related workers situated across 178 countries. This paper attempts to provide a critical historical background for the development of this institution.
Not All Types of Social Networks Are Good: The Dual Effects of Social Networks on Courtesy Stigma
Authors: Tian Longwei , Li Peter Ping , Xie En , Li Yuan 
Published: April 2022

ABSTRACTWhen a firm is accused of serious misconduct, its executives, even those who are nonculpable, are stigmatized by the firm's stakeholders, a phenomenon known ascourtesy stigma. One research stream explores how executives’ social networks mitigate courtesy stigma, with an emphasis on the positive effect of social networks. From the perspective of a social network as an information pipe, we suggest that social networks are a double-edged sword in the context of courtesy stigma because of their distinctiveinsulationandexposuremechanisms. Our proposed hypotheses are supported via event history analysis using data collected from a Chinese sample of listed firms that demonstrated financial misconduct in the period 2007–2016. Our study contributes to the literature on social networks and courtesy stigma by revealing their complex links.
Ryazanian (Berriasian) molluscs and biostratigraphy of the Dutch and Norwegian North Sea area (south of Viking Graben)
Authors: Janssen N.M.M. , Rogov M.A. , Zakharov V.A. 
Published: April 2022

AbstractHerein, Ryazanian (Berriasian) macrofossils from three well cores in the Central Graben (wells B18-02, L06-02, The Netherlands) and on the Jæren High (well 7/7-2, Norway) in the southern North Sea region are described. Macrofossils are mainly represented by buchiid bivalves (Buchia volgensis) and ammonites (Surites,LynniaandPraetollia?). The genusLynniais recorded for the first time outside its topotypical area, and its systematic position and stratigraphic ranges are discussed. Additionally, the studied core sections yielded coleoid remains and a single limid bivalve. Based on the stratigraphic ranges of key ammonite genera (Lynnia, SuritesandBojarkia), the zonation of the Ryazanian stage is reconsidered. Uppermost Volgian to Ryazanian ammonite faunas are quite consistent and diverse but showing a higher degree of similarity throughout the Panboreal Superrealm as compared to those from rest of the Upper Volgian and the Middle Volgian.Buchia volgensisis the only species known from the southern North Sea and East Anglia, which is in strong contrast to the high diversity ofBuchiain East Greenland and the remainder of the Boreal Realm. We hypothesise that such differences in the distribution of ammonites and bivalves in general, and the absence of buchiid species other thanBuchia volgensissouth of East Greenland in particular, are the result of anoxic bottom water conditions in the southern Viking Strait. The unusually wide geographic range ofB. volgensis, which is known from such distant areas as Mexico and the Crimea, suggests a potential higher tolerance of this species to adverse conditions.
‘Armed with the necessary background of knowledge’: embedding science scrutiny mechanisms in the UK Parliament
Authors: Ledgerwood Emmeline 
Published: April 2022

AbstractThe unprecedented circumstances of the COVID-19 pandemic have intensified the demands placed upon parliamentarians to scrutinize and evaluate evidence-based government proposals, making visible the parliamentary mechanisms that enable them to do so. This paper examines the steps that led two such mechanisms to become embedded in the institution of Parliament during from 1964 to 2001: the House of Commons Select Committee on Science and Technology (a scrutiny and information-gathering body) and the Parliamentary Office of Science and Technology (a legislative science and technology advice body). Drawing on official papers, Hansard records and unpublished archival material, this account complements existing studies of the relationships between government ministers and experts. It highlights how individual members of the all-party Parliamentary and Scientific Committee have influenced institutional change. In so doing it exposes some of the challenges confronting Parliament in the scrutiny of science policy from the mid-twentieth century to today. In particular, it reveals MPs’ concerns about their ability to scrutinize science policy in the absence of a select committee on science and technology in the Commons during the 1980s. This shows that parliamentary scrutiny of science was compromised during the very period when the Conservative government under Margaret Thatcher set about making major changes to the organization and funding of government-sponsored research in the UK.

AbstractObjectiveTo document laryngeal framework rupture following voluntary cough-holding as an airway complication of donning a personal protective equipment suit that was too small in size.MethodsClinical record and literature review, with proposition of plausible aerodynamics of the airway injury.ResultsWhilst carrying out his duty in the coronavirus disease ward, a resident attempted to stifle a paroxysm of cough when wearing a personal protective equipment suit that was too small with his neck flexed and restricted. There was a sudden release of pressure, intense pain and swelling in the neck with crepitus. Imaging revealed a non-displaced fracture in the lower end of the partially ossified right thyroid lamina, a cricothyroid membrane tear and subcutaneous emphysema. The symptoms resolved gradually on conservative management.ConclusionThis report underlines the importance of donning appropriately sized personal protective equipment and encouraging its proper use amongst coronavirus disease 2019 caregivers. Non-traumatic laryngeal injury, itself a rare event, has never been reported as a posture-related complication of wearing personal protective equipment.
Chen Mengzhao's storeroom in Park Street, Calcutta. Wartime India-China smuggling, 1942–1945
Authors: Cao Yin 
Published: April 2022

AbstractThis article is about the experiences of three Chinese men who were involved in smuggling between India and China during the Second World War. Chen Mengzhao's rise as a leading figure in India-China smuggling in Calcutta uncovers the hidden links between the black markets in India and China during the Second World War. Gao Wenjie disguised himself as a Chinese army officer and utilized this fake identity to facilitate his smuggling business. Wang Li-an was sent to Calcutta to undertake smuggling for a Chinese government department. In telling these stories, this article argues that most smuggling in modern India and China was undertaken in transnational contexts that resulted in transnational effects. Ironically, the Nationalist government's state-building project to contain India-China smuggling ended by facilitating it. This project was further perceived by the British authorities as a Chinese conspiracy against India's sovereignty. The misunderstanding between the Chinese and British authorities led to the end of Chinese immigration to India in 1945. Overall, this article provides a new perspective to make sense of the tensions between the Chinese, Indian, and British governments during the Second World War.
Confidence, accuracy judgments and feedback in schizophrenia and bipolar disorder: a time series network analysis

Published: April 2022

AbstractBackgroundInaccurate self-assessment of performance is common among people with serious mental illness, and it is associated with poor functional outcomes independent from ability. However, the temporal interdependencies between judgments of performance, confidence in accuracy, and feedback about performance are not well understood.MethodsWe evaluated two tasks: the Wisconsin Card Sorting Test (WCST) and the Penn Emotion recognition task (ER40). These tasks were modified to include item-by-item confidence and accuracy judgments, along with feedback on accuracy. We evaluated these tasks as time series and applied network modeling to understand the temporal relationships between momentary confidence, accuracy judgments, and feedback. The sample constituted participants with schizophrenia (SZ; N = 144), bipolar disorder (BD; N = 140), and healthy controls (HC; N = 39).ResultsNetwork models for both WCST and ER40 revealed denser and lagged connections between confidence and accuracy judgments in SZ and, to a lesser extent in BD, that were not evidenced in HC. However, associations between feedback regarding accuracy with subsequent accuracy judgments and confidence were weaker in SZ and BD. In each of these comparisons, the BD group was intermediate between HC and SZ. In analyses of the WCST, wherein incorporating feedback is crucial for success, higher confidence predicted worse subsequent performance in SZ but not in HC or BD.ConclusionsWhile network models are exploratory, the results suggest some potential mechanisms by which challenges in self-assessment may impede performance, perhaps through hyperfocus on self-generated judgments at the expense of incorporation of feedback.
A very rare cause of sudden cardiac arrest in children: triadin knockout syndrome
Authors: Sulu Ayse , Karacan Mehmet , Ergul Yakup 
Published: April 2022

AbstractTriadin knockout syndrome has been defined as a disease with transient long QT, T wave abnormalities, and extremely severe fatal cardiac arrhythmias in young children. In this report, we wanted to share the characteristics of our two cases who presented with sudden cardiac arrest and were diagnosed with triadin knockout syndrome.Case 1:A 7.5-year-old male patient was referred to our clinic with a history of recurrent syncope and aborted cardiac arrest. There was no family history of sudden death, syncope, or arrhythmia. Physical examination, electrocardiography, echocardiography, and 24-hour rhythm Holter monitoring were normal, and bidirectional ventricular tachycardiaT was detected during the exercise stress test. Genetic analysis revealed a homozygous mutation of c.531_533delinsGG, p.(Lys179Asnfs * 44) frameshift variant in TRDN(NM_006073) gene.Case 2:A 4.5-year-old male was admitted due to syncope during exertion and underwent cardiopulmonary resuscitation due to sudden cardiac arrest. He had family history about sudden cardiac death. Physical examination was normal, and there was borderline QTc prolongation. Bidirectional non-sustained polymorphic ventricular tachycardia was observed at adrenaline provocation test. In genetic analysis, c.568dupA, pII190Asnfs * 2 frameshift variant homozygous mutation was detected in TRDN(NM_006073) gene. Intracardiac defibrillator implantation were performed for both cases. There has not been any event under propranolol and flecainide combination treatment.Conclusion:Triadin knockout syndrome (TCOS) is a rare overlap syndrome characterized by highly malignant arrhythmias, and it is a deadly combination of long QT syndrome and catecholaminergic polymorphic ventricular tachycardia that affects primarily young children. Since lethal arrhythmias are frequently described, genetic testing is very important in these patients. Because, identification of a genetic mutation may be a guide in treatment.
