Published: September 2021

AbstractThis paper describes tests performed with large, post‐installed bonded fasteners installed in concrete of very low compressive strength. Concrete with several strengths were studied, including strength classes under C20/25. The goal was to determine whether such connections could be designed according to EN 1992‐4, as they deviate from the scope of this standard by the fact that the concrete is outside the permissible compressive strength range. Additionally, these tests aimed to cover the knowledge gap regarding bonded fasteners installed with large‐diameter threaded rods, deep embedment depths, and reduced edge distances, since little research has been done in this area. Tests on single fasteners and on a group of four anchors were performed, and the results were compared with the design values calculated according to EN 1992‐4. Conclusions have been drawn, and possible underestimation of the load‐bearing capacity of such anchorages has been quantified.
Intrinsic Localized Mode in a Multiple Mass Dynamic Vibration Systems Using Nonlinear Magnetic Springs
Authors: Lee SangGook , Hirata Katsuhiro , Kato Masayuki 
Published: September 2021

AbstractIntrinsic localized mode (ILM) can be generated in multiple mass‐spring systems using nonlinear springs, and ILM has attracted a lot of attention due to its special vibration modes that are not found in linear systems. However, the difficulty of creating nonlinearity remains a barrier to ILM research. In this paper, we propose a rotating magnetic spring based on magnetic nonlinearity. The nonlinear restoring properties of the proposed magnetic spring are confirmed by finite element method (FEA). Finally, using the restoring properties obtained from FEA, it is shown that ILM can be excited by MATLAB numerical analysis. © 2021 Institute of Electrical Engineers of Japan.

Published: September 2021

AbstractBackgroundFolate deficiency in people can occur in conditions causing increased demand, including haemolytic anaemia. This has not been investigated in dogs with non‐associative immune‐mediated haemolytic anaemia (IMHA).MethodsCohort study of 15 dogs with non‐associative IMHA. Haematocrit (HCT) and serum folate concentrations were measured at presentation and each subsequent venipuncture performed for monitoring. The relationship between serum folate concentrations and HCT was investigated using linear and logistic mixed‐effects regression models and in paired samples using a one‐tailed pairedt‐test.ResultsLow serum folate concentrations occurred in five of 15 dogs. In 126 samples, a significant positive relationship was found between HCT and corresponding serum folate concentrations. A significant relationship was found between dichotomised folate concentrations (below the reference interval or within/above the reference interval) and HCT and between serum folate concentrations and dichotomised HCT (less than or equal/above 0.30 L/L). For paired samples (available in eight dogs), the mean serum folate concentration of samples with the lowest HCT was significantly lower than that of samples in which the HCT first exceeded 0.30 L/L.ConclusionsLow serum folate concentrations were observed in some dogs with non‐associative IMHA. Further studies are needed to determine the cause and investigate whether folate supplementation would be beneficial.
Postmortem findings of secondary brodifacoum poisoning in a kestrel (Falco tinnunculus)

Published: September 2021

AbstractA male common kestrel (Falco tinnunculus) was found dead in a field in April 2019 in the canton of Zurich, Switzerland, and was submitted to the Department for the Protection of Animals and the Environment of the cantonal police Zurich. Because the common kestrel is a protected species, the carcass was forwarded to the Department for Poultry and Rabbit Diseases, University of Zurich, for forensic examination. On necropsy, profuse internal haemorrhage without causal trauma was observed, leading to the suspicion of intoxication with an anticoagulant. Liver tissue samples were sent to the Institute of Pharmacology, Toxicology and Pharmacy of the Ludwig Maximilian University, Munich, Germany, for anticoagulant residue analysis, revealing an amount of 40.3 ng/g brodifacoum, a second‐generation anticoagulant rodenticide. Information from the finding site did not give any evidence of wilful poisoning, thus secondary rodenticide poisoning through intoxicated prey was determined as the cause of death.
Downsizing in total hip arthroplasty. A short stem as a revision implant
Authors: Coutandin Marcel , Afghanyar Yama , Rehbein Philipp , Dargel Jens , Drees Philipp , Kutzner Karl Philipp 
Published: September 2021

Abstract
Background
Short stems have constantly gained popularity in primary total hip arthroplasty (THA) over the last decade. Although cementless short stems are not primarily designed to be used as revision implants, there may be certain indications for which downsizing the femoral component in failed conventional THA is potentially advantageous.

Methods
In this single center retrospective case series, six patients who underwent revision using a calcar-guided short stem after failed THA are presented. The mean follow-up was 3.32 years (SD 0.63 years). The health status was evaluated by the EQ-5D-5L score. Patient reported outcome measurements (PROM) were recorded using the Harris hip score (HHS) and The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Pain and satisfaction were assessed using a visual analogue scale (VAS). Radiographic analysis was performed by evaluating osteolysis, stress shielding, alignment and signs of aseptic loosening. Complications were documented.

Results
At last follow-up the mean EQ-5D-5L index was 0.851 (SD 0.098). Clinical outcome was excellent (HHS ≥ 90) in 4 patients and moderate (HHS 71 and 79) in 2 patients. The mean WOMAC score was 9.20% (SD 12.61%). Pain and satisfaction on VAS were 1.00 (SD 1.15) and 9.17 (SD 0.37), respectively. No major complications occurred. To date, no further revision surgery was needed. Radiologically, no signs of subsidence, aseptic loosening, stress shielding and fractures were obvious.

Conclusion
The present case series indicates that in failed conventional THA downsizing may be considered a treatment option, using short stem THA in selected cases.
Acetabular reconstruction with femoral head autograft in primary total hip arthroplasty through a direct anterior approach is a reliable option for patients with secondary osteoarthritis due to developmental dysplasia of the hip

Published: September 2021

Abstract
Background
Developmental dysplasia is challenging to treat with total hip arthroplasty via the direct anterior approach (DAA). Reconstructing the former anatomy while restoring the acetabular bone stock for future revisions in this young patient collective combined with the known advantages of the DAA would be desirable. The purpose of this study was to analyze the feasibility, radiographic outcome and clinical outcome of primary uncemented total hip arthroplasty with bulk femoral head autograft for acetabular augmentation through a DAA with a minimal follow-up of 12 months.

Methods
A retrospective, consecutive series from March 2006 to March 2018 of 29 primary total hip arthroplasty with acetabular augmentation with bulk femoral head autograft through a direct anterior approach was identified. All complications, reoperations and failures were analyzed. Radiographic and clinical outcome was measured.

Results
24 patients (29 hips) with a mean age of 43 (18–75) years and a mean follow-up of 35 months (12–137) were included. Surgical indication was secondary osteoarthritis for developmental dysplasia of the hip (Hartofilakidis Grade A (n = 19), B (n = 10)) in all cases. We noted no conversion of the approach, no dislocation and no acetabular loosening. The center of rotation was significantly distalized by a mean of 9 mm (0–23) and significantly medialized by a mean of 18 mm (6–29). The bone graft was fully integrated after 12 months in all cases.

Conclusion
Acetabular reconstruction with femoral head autograft in primary THA through a direct anterior approach seems to be a reliable option for the treatment of secondary osteoarthritis in patients with DDH Hartofilakidis grade A and B. Prospective cohort studies with a large sample population and a long-term follow-up are necessary to confirm our findings.

Published: September 2021

ZusammenfassungIm Zuge des EIT RawMaterials-Projektes „ReviRis – Revitalising Post-Mining Regions“ werden Bergbaugebiete weltweit mit ihren Auswirkungen auf die jeweiligen Bergbaufolgelandschaften betrachtet. Ziel des Projektes ist die Entwicklung eines partizipativen, evaluativen Leitfadens (toolbox), der bei der Gestaltung und Umsetzung von Strategien zur Revitalisierung von Bergbaufolgelandschaften und Übergangslandschaften eingesetzt werden kann. Zielgruppen sind regionale und lokale Entscheidungsträger (Industrie, Gemeinden, Raumplaner und Behörden). Starkes Augenmerk wird auch auf die Beteiligung und das Engagement der verschiedensten Interessengruppen, allen voran der lokalen Bevölkerung, gelegt.Am 22. Juni 2021 fand im Zuge des Projektes der erste online Workshop zum Thema „Revitalisierung von Bergbaufolgelandschaften – Untersuchung von Erfolgsfaktoren oder Gründen für Misserfolge“ statt. Das Ziel dieser Veranstaltung war es, ausgewählte Beispiele von revitalisierten Bergbaufolgelandschaften vorzustellen und die Erfolgs- oder Misserfolgsfaktoren des Revitalisierungs- und Managementprozesses darzustellen.Folgende Revitalisierungsprojekte wurden präsentiert:Zinnbergwerk Geevor (Großbritannien), Lavrion Technological Cultural Park (Griechenland), Goldmine Złoty Stok (Polen), Kupfer- und Anhydritbergwerk Lubichów (Polen), Ölschieferbergwerk Ojamaa (Estland), Abenteuerzentrum Kiviõli (Estland), St. Barbara Mine (Kroatien), Steirischer Erzberg (Österreich).Im Zuge dieses Artikels werden die vorgestellten erfolgreichen Projekte näher erläutert, wobei der Schwerpunkt auf der rechtlichen sowie auf der aktuellen Situation in Österreich – am Fallbeispiel des Steirischen Erzberges – liegt. Der Steirische Erzberg stellt insofern ein spannendes Praxisbeispiel dar, dass im Gegensatz zu anderen österreichischen Vorzeigeprojekten wie z. B. zu den Revitalisierungsarbeiten der „GKB-Bergbau GmbH“ oder auch der „Bleiberger Bergwerks Union“ nach Einstellung der Bergbautätigkeit, in Eisenerz gleichzeitig mit vielen alternativen Nutzungen noch immer und auch noch für Jahrzehnte aktiver Erzabbau betrieben wird.
Einbindung von Erzeugungsanlagen mit Vollumrichter in das Überlagerungsverfahren zur Kurzschlussstromberechnung
Authors: Schäkel Nils , Hofmann Lutz 
Published: September 2021

ZusammenfassungIn diesem Aufsatz wird eine Erweiterung des Überlagerungsverfahrens vorgestellt, um das spannungsabhängige Fault Ride Through-Verhalten von Erzeugungsanlagen mit Vollumrichter zur Berechnung des betriebspunktabhängigen Anfangs-Kurzschlusswechselstroms zu berücksichtigen. Zudem werden die physikalischen Grenzen des in den Technischen Anschlussregeln in Deutschland geforderten Kurzschlussstrombeitrags aufgezeigt. In dem entwickelten iterativen Kurzschlussstromberechnungsverfahren führt das Überschreiten der physikalischen Grenzen durch den Kurzschlussstrombeitrag der Erzeugungsanlagen mit Vollumrichter zu Konvergenzproblemen. Zur Identifikation der betroffenen Anlagen werden die zulässigen bzw. unzulässigen Betriebspunkte in Abhängigkeit von der Kurzschlussspannung hergeleitet. Eine exemplarische Kurzschlussstromberechnung zeigt den Einfluss des Vorfehlerzustandes der Erzeugungsanlagen mit Vollumrichter sowie die Auswirkungen einer Wirkstromeinspeisung im Kurzschlusszustand auf den Anfangs-Kurzschlusswechselstrom.

AbstractAimFormer unaccompanied immigrant minors (UMs) now living in the USA are a uniquely vulnerable population. The US Office of Refugee Resettlement shelters provide health services, but most are discontinued once UMs leave the shelters. A systematic review was therefore designed to quantify access to medical, mental, and dental healthcare services by former UMs living in the USA.Subject and methodsThe study protocol was registered with PROSPERO. A search was made in Ovid MEDLINE, Embase, Scopus, and Academic Search Complete in June 2020. Full-text review, data extraction, and data analysis were completed by all authors.ResultsSearches returned a total of 2646 studies, of which 15 met all eligibility criteria. There was an overlap in the services investigated in the studies — 13 assessed mental health, ten assessed medical, and four included dental care. Sample sizes ranged from one to 4809, and there was a wide range of study designs. Some studies included multiple locations. Nine studies demonstrated success in community-based clinics or programs; one in a hospital, four in schools, three in group living settings, and one in U.S. Customs Border Patrol (CBP) custody. Three studies explored access to services post-release from shelters.ConclusionsHealthcare programs at shelters, schools, and in the community have provided some screening and diagnosis of medical, mental health, and dental conditions for UMs, but multiple financial and cultural barriers make ongoing treatment difficult to access. Long-term studies following UMs in shelters and post-release through adulthood are needed to help create new, or modify existing, programs, to adequately support UMs now living in the USA.
Caring for Patients Without Documentation Status: What Motivates Us and Sustains Us
Authors: Kaki Dahlia A. , Dutt Anjali , Alwan Riham M. 
Published: September 2021

AbstractRestrictive policies and limited resources create challenges for care delivery for patients without documentation status (PWDS). This study explores the motivators and sustainers for healthcare providers serving PWDS. Twenty-four direct providers in public and private sectors were interviewed using semi-structured, in-depth interviews. Two members of the research team independently coded interviews using inductive thematic analysis. Four major themes emerged illustrating intrinsic and extrinsic sources that motivated and sustained providers: (1) a sense of calling to serve their community; (2) solidarity is sustaining; (3) organizational culture as a key element for provider engagement; (4) insight into necessary change. Providers who care for PWDS are driven and sustained by internal motivations and a sense of solidarity in working towards better care access for their marginalized patients. Findings illustrate the importance of recruiting and retaining providers with histories of recent migration. Immigration and healthcare policy reform may improve provider workflow.

Published: September 2021

AbstractDasineura oleae (Angelini, 1831) (Diptera: Cecidomyiidae), the olive leaf gall midge, is a pest of olive crops that was not problematic in Italy until 2016 when a massive infestation of this pest was reported in a small region in central Italy. We identified infested olive orchards using farmers’ reports and quantified the pest infestation level and parasitism rate in each field. We also explored the effect of the landscape on both the pest and parasitoids using the abundance of olive crops and semi-natural habitats and the Shannon index, estimated at four different scales (250 m, 500 m, 750 m and 1000 m buffers around the sampling points). The results showed a small-scale effect on the parasitism rate and a large-scale effect on leaf infestation mediated by the Shannon Index. Moreover, some preliminary results showed that the parasitism rate was high in sites where plants associated with D. oleae parasitoids were present in the adjacent semi-natural habitat. Further studies are needed to validate our findings on the effect of landscape and vegetation on the natural enemies of D. oleae in order to develop new suppression strategies.

Published: September 2021

AbstractAt present, in the aspect of numerical simulation of a cycloid pump, most researchers are based on CFD (computational fluid dynamics) to analyze the pump under different operating conditions (such as speed, temperature), and the performance of a pump under FSI (fluid solid interactions) is rare. Firstly, a model of cycloidal pump is established in COMSOL. The simulation results obtained by applying CFD and FSI are verified by experiments. Then, the flow in the rotating region and the inlet and outlet cavities are analyzed. Finally, through further analysis of the internal flow, improved design scheme of the cycloid pump is put forward, the inlet flow of the cycloid pump increased by 5.8% compared with the unoptimized, the inlet flow pulsation decreased by 32.7%. The discharge flow of the cycloid pump increased by 16.3%, the pulsation rate of discharge flow decreased by 47%. It provides a reference for other pump research, analysis and improvement design.
The Institutional Foundation of Countermobilization: Elites and Pro-Regime Grassroots Organizations in Post-Handover Hong Kong
Authors: Yuen Samson 
Published: September 2021

AbstractCountermobilization has been a common strategy for autocrats to counteract the threat of opposition. Although the use of countermobilization has drawn scholarly attention, research on the mechanisms that enable countermobilization remains limited. This article underscores the role of political institutions in allowing autocrats to carry out countermobilization through incentivizing elites to serve as a bridge between the state and the masses. Focusing on the case of Hong Kong, where pro-government countermobilization is rising along with pro-democracy challenges against the hybrid regime, the article argues that countermobilization is enabled because societal elites are incentivized through political institutions to organize the masses and develop mobilization capacity through grassroots organizations. Using original elite biographical data and organizational data, the article shows that elites with more ties with grassroots organizations are more likely to remain in office in the Chinese People's Political Consultative Conference. The findings offer an institutionalist explanation of how authoritarian rulers enact countermobilization by leveraging elite intermediaries and their grassroots networks. In this light, political institutions can serve as a conduit for the state to extend social control.
RECONSTRUCTING STATE OBLIGATIONS TO PROTECT AND FULFIL SOCIO-ECONOMIC RIGHTS IN AN ERA OF MARKETISATION
Authors: Birchall David 
Published: September 2021

AbstractStates hold international human rights obligations to protect rights-holders from infringements by third parties and to fulfil access to rights. States also increasingly rely on businesses to provide essential human rights resources, including for housing, food, and healthcare. How these obligations apply where States rely on businesses has not been adequately conceptualised, particularly regarding the scope of business infringements in this context, and how the obligation to fulfil relates to market regulation. The Committee on Economic, Social and Cultural Rights has not directly addressed these questions, but recent General Comments develop ambitious regulatory obligations in this area. However, their methodology is questionable, often collapsing the distinction between obligations to protect and to fulfil. This article reconstructs the obligations to provide distinct content under each. It delineates State duties to protect from profiteering and to fulfil human rights through market regulation. It concludes by arguing that this reconstruction may challenge central aspects of globalised capitalism based on the human rights harm inherent therein.

AbstractObjectiveTo assess the influence of presbylarynx and presbycusis on Voice Handicap Index and emotional status.MethodsA case–control, prospective, observational, cross-sectional study was conducted of patients aged 65 years or older referred to an otorhinolaryngology department from January to September 2020. Presbycusis was assessed by pure tone and vocal audiometry. Each subject underwent fibre-optic videolaryngoscopy with stroboscopy, and presbylarynx was considered when two or more of the following endoscopic findings were identified: vocal fold bowing, prominence of vocal processes in abduction, and a spindle-shaped glottal gap. Each subject completed two questionnaires: Voice Handicap Index and Geriatric Depression Scale (short-form).ResultsThe studied population included 174 White European subjects, with a mean age of 73.99 years, of whom 22.8 per cent presented both presbylarynx and presbycusis. Multivariate linear regression revealed that only presence and severity of presbylarynx had an influence on Voice Handicap Index-30 scores. However, both spindle-shaped glottal gap and presbycusis influenced Geriatric Depression Scale scores.ConclusionPresbylarynx has a strong association with the impact of voice on quality of life. Presbylarynx and presbycusis seem to have a cumulative effect on emotional status.
