Influence of hydrodynamic planetary journal bearings on the NVH-behavior of wind turbines

Published: February 2025

Abstract
The growth of the wind energy sector is confronted with stringent noise regulations, particularly concerning tonal noises from wind turbines (WTs). These tonal noises, originating from drivetrain vibrations such those caused by gear meshing, are transmitted as structure-borne sound through the WT and ultimately emerge into the surrounding environment as sound emissions. Given that tonal noises are irritating to humans, there is a need for early-stage noise, vibration, and harshness (NVH) mitigation.
Recently, a trend has emerged towards replacing planetary rolling bearings (PRBs) with planetary journal bearings (PJBs) in the gearboxes of WT drivetrains. This shift offers several advantages, including reduced installation space, increased reliability, and improved vibration reduction, the latter being especially important for complying with noise regulations. Thus, this paper aims to analyze the impact of using PJBs on the NVH behavior of WTs. To achieve this, the dynamic behavior of a generic 5 MW WT under nominal operational conditions is simulated using a multi-body simulation (MBS) model. The findings of this study indicate significant potential for enhanced noise mitigation through the adoption of PJBs, with the bearing main parameters playing a role in the damping characteristics of the bearing.

Abstract
When students learn with–and from–other students, it is called peer-assisted learning (PAL). How undergraduate medical students use their peers for their clinical-reasoning learning process remains unclear, although literature suggests that it is a promising learning strategy at this stage. This research therefore explores the question: ‘How is PAL manifested in the clinical learning environment of undergraduate medical students with regard to developing clinical-reasoning skills?’. A constructivist paradigm with a sociocultural theoretical framework was adopted for this research, using PAL and workplace learning as theoretical background. Focused ethnography and a combination of template and open coding was used to gather and analyze qualitative data. Twenty semi-structured interviews were conducted with nine students, four residents, and seven clinical supervisors. A total number of 31.5 h were used for five clinical observations. Following categories were used to describe the data: (1) the role of PAL in the clinical-reasoning learning practice, in which PAL-theory was placed alongside clinical practice, (2) the role of different actors during PAL and (3) the PAL environment, in which contextual factors have been scrutinized. Students deploy various categories of PAL to advance their clinical-reasoning skills, although they were largely unaware of these processes, and facilitation of PAL is not consistently provided. Three topics of discussion are identified that need to be acknowledged: (1) the design of a PAL environment that is conducive to collaborative learning, (2) the shifting roles of peers when they enter clinical practice, and (3) the individualistic tendencies of students that can hamper PAL. Future research could focus on stimulating and facilitating PAL among the next generation of students and integrating PAL into the clinical practice workflow.
Unlearning modernity? A critical examination of the Intergovernmental Panel on Climate Change (IPCC)
Authors: Wagner Niklas , Hornidge Anna-Katharina 
Published: February 2025

Abstract
Modernity's ideals of progress through industrialisation, coupled with rationalist views of value-free and neutral science guiding policymaking, have been driving forces behind the climate crisis and related injustices. Post-colonial scholarship calls for unlearning this modernist paradigm. This study examines the extent to which the Intergovernmental Panel on Climate Change (IPCC), the preeminent global authority on climate change knowledge, is both shaped by the procedural logic of Eurocentric modernity and the tendencies towards unlearning these modernist characteristics in favour of more pluralistic, co-productive approaches. Through an inductive-deductive qualitative methodology, including semi-structured interviews with IPCC authors and policymakers at international climate conferences, this paper finds the IPCC to be situated in a tension field between modernity and unlearning it. On the one hand, the IPCC is constrained by path-dependencies of Eurocentric modernity, manifested in the linear model of knowledge transfer, the differentiated systems logic of science and policy spheres, and the privileging of Western scientific expertise as universally valid and apolitical. On the other hand, the study also identifies emergent tendencies within the IPCC towards broadening disciplinary diversity, incorporating alternative epistemologies like Indigenous and Local Knowledge, and fostering co-productive collaborations between scientists and policymakers. These nascent "unlearning" efforts signal cracks in modernity's edifice, though limitations and potential risks caution against overstatement. By highlighting this critical juncture, the paper contributes empirical and conceptual insights into the IPCC's transition from modernist constraints towards more pluriversal climate responses. This analysis sheds light on the IPCC's evolving role in shaping global climate governance and the ongoing struggle to redefine climate knowledge production.
Perceived effectiveness and intrusiveness of school security countermeasures among parents, students, and staff
Authors: Byrd Katie , Kapadia Kevin , John Richard 
Published: February 2025

Abstract
This study evaluates the perceptions of school security countermeasures among parents, recent students, and staff (n = 1105) recruited via Prolific.com. The survey elicited participants’ perceptions of safety and countermeasure effectiveness and invasiveness. Results show broad acceptance of measures like emergency drills, door locks, and security cameras, while more invasive measures, including armed staff, bag inspections, and clear bag policies, generate discomfort. A binary logistic regression found that perceived safety was negatively predicted by a desire for additional countermeasures and positively predicted by perceptions of countermeasures as both comfortable and effective. Socioeconomic factors, like household income, were also positively related to students’ sense of safety. Future research should examine the broader impacts of security measures on student well-being and the school environment.
Demographic and topographic findings suggesting poor response to crosslinking-iontophoresis in patients with progressive keratoconus
Authors: Touriño-Peralba Rosario , Rodríguez-Lago Julio , Lamas-Francis David , Martínez-Pérez Laura , Rodríguez-Ares Teresa 
Published: February 2025

Abstract

Purpose
To evaluate demographic and tomographical parameters in predicting treatment response following transepithelial iontophoresis-assisted corneal cross-linking (I-CXL) for progressive keratoconus.

Methods
Forty eyes (20 aged < 19 years and 20 aged ≥ 19 years) underwent I-CXL treatment between 2016 and 2022. Progression criteria based on the ABCD system, changes in asphericity (Q), demographic factors and keratoconus phenotypes were evaluated. Subjects were followed for 24 months after procedure.

Results
Sixty percent of participants were male. The mean age at the time of treatment was 21.0 ± 6.0 years. All tomographical values showed progression after 2 years of follow-up (p < 0.05), particularly during the first 6 months, except for anterior curvature. Within the ABCD grading system, we observed: A) an increase in anterior curvature, more evident with lower initial values; B) an increase in posterior curvature, more pronounced with higher initial values. Two years after I-CXL, 20% of subjects met progression criteria in two or more parameters, with 62.5% being under 19 years of age. Patients with a family history of corneal ectasia exhibited a mean KMax progression of 1.94D ± 1.88, (p = 0.046). Only phenotypes 3 and 4 showed progression. Although patients under 19 years showed greater progression in all tomographical variables at the end of the study, this difference was not statistically significant.

Conclusion
Treatment with I-CXL did not stop progression in the variables studied two years after the procedure in an effective manner, especially in patients younger than 19 years. A family history of corneal ectasia and subtype 4 keratoconus predicted a less favourable response to I-CXL.

Abstract
The need for the production of synthetic polymers from renewable and sustainable resources also affects the area of emulsion polymerization. The bio-based monomer (BBM) was synthesized from camelina oil (CO) and itaconic acid through transesterification and epoxidation of CO, followed by itaconation, resulting in a blend of methyl esters of CO-originated fatty acids functionalized with reactive methyl itaconate groups. Various amounts of BBM (0−30 wt% of BBM in the total monomer mixture) were copolymerized with standard petroleum-based acrylic monomers (specifically methyl methacrylate, butyl acrylate, and methacrylic acid) using the emulsion polymerization technique to obtain film-forming latexes. Infrared and Raman spectroscopies evidenced the successful incorporation of BBM into the structure of latex polymers. The ultra-high molar mass nanogel fraction was detected by asymmetric flow-field flow fractionation coupled with a multiangle light scattering (AF4-MALS) for the BBM comprising copolymers; the higher the BBM content, the more extensive the nanogel fraction. Cross-linking of latex polymers induced by BBM testified to the reactivity of itaconated functions in emulsion polymerization and provided additional evidence of the copolymerization ability of BBM. The incorporation of BBM also resulted in pendulum hardness and glass transition temperature enhancement (about 11% and 9 °C, respectively, in the case of 30 wt% of BBM content in contrast to 0 wt% of BBM content in the copolymer). Coatings with excellent transparency and gloss were obtained from all latexes regardless of the BBM content used. Slightly increased water repellency (about 7 ° increased water contact angle value) and significantly improved water whitening resistance of the coatings (about 80% decreased water whitening after 1-day long water exposure) were found for coatings comprising 30 wt% of BBM in the copolymer, where the water whitening phenomenon was highly dependent on the BBM content.

Abstract
The current study illustrated a mediation model of different aspects of family environmental factors in predicting short-term memory and social understanding in Chinese children. The study investigated how children’s short-term memory and social understanding were predicted by family environment factors, including socioeconomic status, home crowdedness, household chaos, and the number of children’s books at home (books) among 525 children in Hong Kong and Mainland China. Data on social understanding, socioeconomic status, crowdedness, household chaos, and books were collected by parent questionnaires. Both verbal and visual short-term memory were measured individually. The results showed that the books mediated the role of crowdedness to both verbal and visual short-term memory in Mainland China, whereas in Hong Kong, crowdedness directly predicted two short-term memory with socioeconomic status controlled. Moreover, the role of crowdedness to social understanding is fully mediated by household chaos in Hong Kong and by both household chaos and books in Mainland China. Our study highlighted that manipulating soft aspects of family environmental factors (maintaining an organized, less chaotic family environment, putting more books at home) could enhance children’s fundamental short-term memory capacity and social functioning.

Abstract
We examined the socioeconomic importance of goat farming on the island of Socotra. The study included 154 participants from various areas. These data were collected via a questionnaire and statistically analyzed using the Bayesian approach and Kruskal–Wallis test to offer insights into the subject matter. The collected data included important quantitative parameters, such as feeding, watering, herd composition, milk production, and mortality, as well as subjective parameters, including the breeders’ reasons for keeping goats. Our study revealed that the main reason for keeping goats on Socotra Island is livelihood purposes (60%), followed by cultural reasons (22%), whereas 18% of respondents keep goats as a companions. In terms of herd composition, generally a Socotri family keeps an average of 107 individuals per herd, of which 59% are adult females, 32% are young under six months, and 9% are adult males. Reproduction patterns indicate that the goats breed twice a year, primarily in May and October. For milk production, goats on Socotra produce an average of 368 ml/day on an annual basis, and the highest production is observed in the mountains. The study also revealed that goats are primarily slaughtered for social reasons, such as family attendance and weddings (55%). According to the respondents, the main cause of mortality in goats was disease (40%). The results of this study have implications for understanding the management of goat farming on the island and conserving the island’s biodiversity.
Identifying urban hotspots of potential bird and pedestrian encounters through corridor overlap

Published: February 2025

Abstract
One way people living in urban areas interact with wildlife is through encounters with birds. Research shows that visual and acoustic interactions with birds enhance the quality of life for city residents. However, global habitat loss and fragmentation have led to declines in most urban bird populations. As urbanization accelerates worldwide, it is essential to find ways for bird populations to thrive in cities while meeting citizens’ cultural ecosystem service needs. This study utilized least-cost path models to identify (i) potential ecological corridors between green spaces for six Dutch urban bird species experiencing population decline and (ii) locations that present a high likelihood of encounters between these birds and pedestrians in urbanized areas. Using expert knowledge, we simulated multiple least-cost corridors among nine green spaces in the Municipality of Utrecht. Additionally, we determined the best potential paths for pedestrians between the same nine green spaces based on citizen science data. Our results revealed that the multi-species nature of bird corridors varies, and there is limited overlap between these corridors and the simulated pedestrian paths. Nonetheless, most bird corridors are situated within 20 m of pedestrian paths, indicating hotspot areas with high potential for bird-pedestrian encounters, particularly near the Utrecht city center. We contend that locations where pedestrian paths intersect or are close to the simulated bird corridors are ideal for interventions aimed at increasing landscape permeability for the six bird species, ultimately enhancing the chances of encounters between birds and pedestrians. Finally, we proposed conservation measures based on our findings that benefit both the studied bird guilds’ population growth and the daily lives of citizens.

Abstract
Lake Bosumtwi in tropical Ghana has been known for its recurrent fish kills, but they have recently been reported to happen less frequently. The lake formed in a meteorite impact crater in Ghana, West Africa. It plays an important role for the local inhabitants for recreation and for fisheries. The lake is deep, and recent observations indicate that recirculation is incomplete. In general, the deep water is anoxic. Fish kills have been associated with the mixing events in the slightly colder rainy season. As unpleasant smells from the water during deep mixing had been reported, the question arose whether toxic gases that had accumulated in the deep water could be responsible; namely, hydrogen sulphide or large amounts of carbon dioxide were considered the most probable candidates. The analysis of the water properties, however, did not detect any hydrogen sulphide nor immensely large concentrations of carbon dioxide. On the contrary, the presence of large amounts of bound nitrogen could be substantiated. We hence concluded that most probably bound nitrogen was responsible for the fish kills on two paths (1) as bound nitrogen as ammonium forms toxic ammonia when mixed into high pH surface water and (2) depletes oxygen when it is oxidized in the surface waters.

Published: February 2025

Abstract

Background
Cementless fixation in total knee arthroplasty (TKA) has been associated with higher revision rates in the past. However, due to advancements in design, as well as surgical techniques, cementless TKA performance has significantly improved. The advantages of cementless fixation include reduced cement-related complications, shorter operating times, and the potential benefits of osseointegration. We aim to assess the improvement in revision rates for cementless TKA over the last 9 years based on international registry reports.

Methods
A comprehensive retrospective review was conducted of six major English-speaking knee arthroplasty registries across the world including the National Joint Registry of England and Wales, Northern Islan Isle of Man and Guernsey (herby referred to as British), Swedish, Canadian, American, Australian, and New Zealand National Joint Registry. Data was collected from the year 2014 along with the most recent annual report published: 2022 or 2023. Data points collected included usage rates of cemented and cementless prostheses for primary TKA, their respective revision rates, and indications for revision.

Results
Across four databases, there was an average 8.3% increase in the utilization of cementless fixation for primary TKA over the past decade. Three registries reported a reduction in revision rates for cementless fixation. Lower revision rates for cementless compared to cemented TKA were observed in the most recent American (3.2% cemented vs. 2.8% cementless) and New Zealand annual reports (11.8% cemented vs. 4.5% cementless). In 2022, the British registry reported lower rates of revision for infection with cementless fixation (0.56 vs. 0.89).

Conclusion
International registries demonstrate increased utilization of cementless TKA. Cementless TKA was reported to have lower revision rates in the most recent US and New Zealand annual reports when compared to cemented TKA.
The Recast Single Permit Directive: an assessment of its changes for the rights of third-country nationals
Authors: Melin Pauline 
Published: February 2025

Abstract
Originally adopted in 2011, the Single Permit Directive provides for a procedure with one single permit for both work and residence for third-country nationals in EU Member States. The Single Permit Directive also grants a uniform set of rights for single permit holders. In 2022, the European Commission proposed to recast it in order to make the procedure more attractive and efficient; to clarify the scope; to strengthen the equal treatment rights; and to better protect single permit holders against exploitation. This contribution will evaluate whether the Recast Single Permit Directive adopted in 2024 meets those expectations.

Abstract
One of the principal challenges of the current and next century’s environmental, scientific, and technical areas is undoubtedly the exploration of carbonate rocks. The role of in-depth understanding and extensive knowledge of subsurface in petroleum exploration and production is undeniable. This industry has been furnished with much information regarding the petroleum industry due to technological development. However, as a result of the nature of the subsurface many uncertainties exist that need to be addressed. Recently, the aforementioned uncertainties have been dealt with by the potential tools provided by investigating the effective parameters such as facies, diagenesis, fractures, and sedimentary environment. Some topics of investigation are recommended in the form of research questions. One question is as follows: What are the research gaps and prospective research directions for carbonate rock exploration? Previously proposed hydrocarbon content determination models in carbonate rocks have raised questions due to the complicated systems and inherently heterogeneous nature. The key purpose of this article is to deeply review the literature to find the exploration paradigms of carbonate rocks, to evaluate the existing models for their prediction in carbonate rocks of different types, and to shed light on the future routes of such studies. For this purpose, the articles presented in different databases from 1960 to 2022 have been reviewed. In the present study facies, fracture, sedimentary environment, and diagenesis parameters have been considered as the criteria for the article selection. To provide the researchers with meritorious assistance to develop a deep knowledge of carbonate rock exploration paradigms in new settings and to develop more effective deployment approaches, the proposed concept map has been prepared. It should be noted that despite the direct relationship generally observed between permeability and porosity, in practice it is not possible to develop the same general relationship for porosity and permeability because the controlling parameters of carbonate rocks vary significantly in each field and formation. Therefore, by examining the logs of several wells and interviewing experienced employees of the oil company about the case study oilfield, they concluded that the contribution of porosity was not considerable and that fracture in production is more effective than vugs or decent porosity. The porosity obtained from the total field logs was 4% and its permeability was obtained from the core and with the help of equations and fracture models.
