Scanning Probe Microscopy Techniques for Studying the Cell Glycocalyx

The glycocalyx is a brush-like layer that covers the surfaces of the membranes of most cell types. It consists of a mixture of carbohydrates, mainly glycoproteins and proteoglycans. Due to its structure and sensitivity to environmental conditions, it represents a complicated object to investigate. Here, we review studies of the glycocalyx conducted using scanning probe microscopy approaches. This includes imaging techniques as well as the measurement of nanomechanical properties. The nanomechanics of the glycocalyx is particularly important since it is widely present on the surfaces of mechanosensitive cells such as endothelial cells. An overview of problems with the interpretation of indirect data via the use of analytical models is presented. Special insight is given into changes in glycocalyx properties during pathological processes. The biological background and alternative research methods are briefly covered.
Flood Label for buildings – a tool for more flood-resilient cities

River floods are among the most expensive natural disasters in Europe. Traditional flood protection methods are not sufficient anymore. It is widely acknowledged in the scholarly debate and in practice of flood risk management that traditional flood protection measures such as dikes need to be complemented with measures to increase the resilience of cities. For cities to become flood-resilient, actions by land users (and homeowners) are required. Currently, land users insufficiently implement measures to mitigate flood-induced damages. Reasons for this include the lack of knowledge about potential measures and the benefits as well as lack of tailored information on flood risk. In this paper, a tool is discussed that addresses these two issues: the German Flood Label for buildings (Hochwasserpass). It is discussed how such a tool can create awareness by land users and how it can trigger the realization of precautionary damage mitigation measures. It will then be discussed how such a tool needs to be embedded in a strategic governance arrangement between land users, water authorities and insurance companies to ultimately achieve flood-resilient cities.
Celebrity CEOs, digital transformation and firm performance in China: the moderating role of controlling shareholders and institutional investors

Background business leaders’ social status significantly impacts companies’ strategic direction and performance. Digital transformation, an important tool for companies to enhance competitiveness and resilience, plays an important role in the relationship between executive background and firm performance. Objective To investigate the impact of celebrity chief executive officers (CEO) on firm performance through digital transformation. Method Using data from companies listed on the main boards of the Shanghai and Shenzhen Stock Exchanges between 2017 and 2021, this study explored the relationship between celebrity CEOs, digital transformation, and firm performance. Result Celebrity CEOs significantly enhanced a firm’s digital transformation. However, this effect weakened when controlling shareholders and institutional investors held more shares. Additionally, the study showed that celebrity CEOs can improve firm performance through digital transformation. These findings were robust across a range of sensitivity analyses. Conclusion This study contributes to understanding celebrity CEOs’ decision-making motivations and economic impacts from a psychological perspective while also providing valuable insights for driving digital transformation within companies.
Geology, alteration, and mineralisation of the Golpu Porphyry and Wafi Epithermal deposit, Morobe Province, Papua New Guinea

The Golpu porphyry and Wafi epithermal deposit of Papua New Guinea contains contrasting styles of epithermal veins and alteration that overprinted early-formed porphyry-style mineralisation. Golpu is the easternmost and oldest porphyry deposit in a previously unrecognised belt that includes most of the porphyry deposits in the New Guinea Orogen. This metallogenic belt was formed in an orogenic regime that was driven by west-directed, low-angle subduction of an antiformal slab of oceanic lithosphere (the Solomon Sea Plate). The regional stratigraphy at Golpu comprises Mesozoic metasedimentary rocks of lower to middle greenschist metamorphic facies. These rocks were intruded in the study area by Golpu and Nambonga diorites, which have calc-alkaline to high-K calc-alkaline arc geochemical characteristics. Early porphyry veins and alteration followed emplacement of the Golpu diorites. Porphyry activity culminated in the main stage of Cu-Au mineralisation around 8.67 ± 0.02 Ma, resulting in an unusually high-grade (1 Gt @ 0.90% Cu and 0.63 ppm Au) and vertically elongated (> 1.8 km) orebody. Golpu sulphides define a zonation pattern from chalcopyrite with trace bornite, to chalcopyrite > pyrite, to distal pyrite > chalcopyrite. They also define zonation in sulfur isotopic compositions (e.g., O34s sulfides from proximal -0.9 to distal +2.0 ‰). A maar-diatreme breccia complex was emplaced after the Golpu porphyry mineralisation, followed by the main stage of Wafi epithermal mineralisation and alteration. Zones of pervasive high sulfidation alteration containing quartz, alunite, pyrophyllite, kaolinite, dickite, and diaspore occur above and overprint the Golpu porphyry. These zones contain vein and disseminated pyrite - covellite - chalcocite - tennantite ± enargite ± bornite atop the porphyry, to distal disseminated pyrite - sphalerite ± tennantite. O34S alunite values vary from +6.3 ‰, directly above Golpu, to +19.4 ‰, 600 metres west of Golpu. An arcuate zone of intermediate sulfidation epithermal carbonate - sulfi de ± quartz ± adularia veins and montmorillonite - chlorite ± muscovite ± illite alteration occurs along the margins of the high sulfidation domain. Most of the Wafi epithermal gold resource (136 Mt @ 1.70 ppm Au) occurs in the intermediate sulfidation zone nearest the Wa! high sulfidation alteration. The intermediate sulfidation epithermal mineralisation transitions down the north-dipping Compass fault into the Golpu porphyry environment, where sparse veins of tennantite - sphalerite - galena - chalcopyrite are interpreted as the basal component of intermediate sulfidation epithermal veins. The temporal and spatial configuration of veins and alteration assemblages at Golpu and Wafi indicate that the Golpu porphyry was the causative intrusive complex for both porphyry and epithermal mineralisation. Uplift and exhumation during the life of the porphyry system was driven by low-angle subduction, and resulted in a shift from porphyry to epithermal magmatic-hydrothermal activity over a period of 0.25 to 0.40 m.y.

The effect of active learning strategies on developing oral reading skills in low-achieving native-speaker Arabic students

Reading constitutes a multifaceted cognitive activity encompassing skills such as recognizing, understanding, and analyzing linguistic symbols. Proficiency in reading holds great importance as it serves as an educational tool and pathway for acquiring knowledge and skills and promotes the development of cognitive, linguistic, and physical abilities and aptitudes. The present study investigated the effect of active learning strategies on the development of Arabic oral reading skills for low-achieving second-grade students in remote areas of Jordan. The study population comprised 170 students, out of which a sample comprising 20 low-achieving second-grade pupils (11 females and nine males), was purposefully selected based on grades (less than 60%) in the Arabic language course. A pre-experimental design involving a one-group pretest-posttest research was used. The study identified 17 oral reading skills that the students needed to master. Over seven weeks, the participants were taught using active learning strategies, including visiting guests, learning by playing, telling the story, and peer education. The results showed statistically significant differences in the students' levels of oral reading skills due to the use of active learning strategies. The study recommends paying greater attention to the basics of teaching Arabic, particularly for students in the first three grades. There is also a need to apply active learning strategies to develop oral reading skills for students' reading proficiency, as weaknesses in these skills can lead to academic failure and negatively impact their lives.
Physicochemical and Microbiological analysis of tube-well water from Noakhali district, Bangladesh

Tube-well water is thought to be free of microbial contamination due to the natural filtering ability of the subsurface environment. However the physicochemical and microbiological quality of this water may deteriorate due to the inappropriate installation of tube-wells and improper sanitation condition. The present study was undertaken to investigate the physicochemical and microbiological parameters of tube-well water in the Noakhali district of Bangladesh. 20 tubewell water samples from 10 separate locations were selected for this investigation from Noakhali Sadar Upazila in Noakhali district. In physiochemical analyses, temperature, pH, electrical conductivity (EC), salinity and total dissolved Solids (TDS) was determined by standard methods whereas, microbial analyses was conducted for total viable count (TVC) & for the determination of E. coli, Vibrio cholera, Vibrio parahaemolyticus, Salmonella spp. The result of the study revealed that the physicochemical parameters of the tube-well water samples are not satisfactory. All the tube-wells were grossly contaminated with bacteria E. coli, Vibrio cholerae, Vibrio parahaemolyticus but no wells are contaminated with Salmonella spp. Good and proper environmental and personal hygiene must be maintained especially by the users of those wells to prevent their contamination with bacterial pathogens.
Developing More Appropriate Culvert Blockage Factors for Use in Flood Modelling Studies on the Sunshine Coast

Culverts are often used to convey floodwaters under roadways and other obstacles during rainfall events. Vegetation and debris emanating from upstream urban catchment areas can become mobilised and transported downstream during rain events. This debris can often become trapped and cause blockages in the culvert, resulting in increased upstream water depths and flooding. Flood and hydrological modelling studies generally attempt to consider any impacts due to the implementation of culverts, and in particular, the extent of the flooding should the culvert become blocked. Current culvert design guidelines suggest that a blockage factor ranging from 10% to 50% blockage should be applied for typical storms with some guidelines recommending up to 100% blockage be applied for severe storms. This study in partnership with the Sunshine Coast Council investigated whether or not the current guidelines for the applied blockage factors used in hydrological models are appropriate for the Sunshine Coast region. This was achieved through the use of a Froude-scaled physical model of a real world site that was constructed on a specially design culvert testing rig at the University of the Sunshine Coast. A variety of flowrates and suitably scaled debris were tested. ; Submitted in the fulfilment of the requirements of the degree of Bachelor of Engineering (Civil Engineering), University of the Sunshine Coast, 2015.
The Participation of Students with Autism in Educational Robotics: A Scoping Review

Educational robotics (ER) is a growing interdisciplinary field that is attracting increasing attention in inclusive or special education settings. It provides a suitable educational environment for the participation of students with autism, through which they can utilize their main strengths and interests. Strengths-based vs. deficits-based approaches recognize the strengths and interests of autistic children as the starting point for their inclusion in school and the community. The scoping review was developed as the best knowledge-synthesis method for summarizing the pertinent research on the participation of students with autism in educational robotics for their successful inclusion. Forty-five studies were included and analyzed to address the main objectives, the mapping of contextual dimensions, and the specific characteristics of the educational robotic activities where the participation of students with autism occurred. The data were extracted into a charting framework, and a narrative analysis was adopted for the knowledge synthesis. According to the results, the research on the participation of children with autism is limited and has focused primarily on educational robotic activities, failing to adequately explore other dimensions that affect the successful participation and inclusion of students with autism in educational robotics.
SCOPE of Open Education: A New Framework for Research

The field of open education and research on the topic has notably expanded since the introduction of the term 20 years ago. Given these developments, a framework to structure research inquiry is necessary to ground and organize findings in open education. We propose the SCOPE framework for open education research: social justice, cost, outcomes, perceptions, and engagement. In this article, we explain how this framework emphasizes the need for social justice at the forefront of open education research. In addition, we incorporate existing theories in social justice, motivation, cognition, pedagogy, and engagement into each of the components to propose theoretical connections to future open education research. We suggest areas in which future research is needed. Finally, we conclude with suggestions as to how the SCOPE framework may be useful when connecting open education to open science and open scholarship as well as a call for considering intersectionality and critical methods in quantitative research (QuantCrit) in future inquiry.
Political news on Instagram: influencer versus traditional magazine and the role of their expertise in consumers’ credibility perceptions and news engagement

Introduction Social networking sites (SNS) are increasingly used by consumers to read and share political news. In this context, Instagram plays an important role due to its prevalence and visual characteristics. However, previous research has highlighted that consumers fail to identify the source of online news, though source characteristics were shown to be vital for news credibility perceptions. Nevertheless, research on whether and which source characteristics have an influence on Instagram consumers’ credibility perceptions and news engagement intentions are lacking. The present study addresses this empirical gap by investigating potential effects of source expertise and source type on source credibility, message credibility, news engagement intentions, and personal involvement regarding political news on Instagram. Method We randomly presented participants with political news posts from one of four sources, either the Instagram representation of a fictional news magazine or influencer with or without political expertise. Participants assessed the perceived credibility of the source and the news, their news engagement intentions, and personal involvement. Results We analyzed data from 416 participants. Results showed significant main effects of source expertise on each of the dependent variables. Those were shown to be indirect effects through personal involvement. There were hardly any effects of source type. Discussion These results provide new insights into the role of source expertise on credibility perceptions and news engagement intentions, and provide insights into the comparison between influencers and Instagram representations of traditional news magazines. Theoretical implications for future research and practical implications for content creators, users, and SNS platforms are discussed.
Fault Vertical Segmentation Growth and Determination of Oil Source Fault in Fuyang Oil Layer in Sanzhao Depression

It is proved that fault possesses a typical characterisc of vertical segmentation growth if there is competent difference according to field observation, typical seismic analysis and physical modeling. Fault evolution can be divided into three stages by competent difference: formation of lower fault,segmentation of upper and lower fault and formation of thoroughgoing fault. Taking Sanzhao depression as an example, rock mechanical properties and fault−related fold theories prove that there widely exists faults in sandstone layer of Fuyang oil layer, whose propagation is stopped by mudstone in Qingshankou formation member, leading to the formation of fault vertical segmentation growth. Combining reservoir careful anatomy, it can be indicated that the main oil source faults of the “reversed” migration in Fuyang oil layer must keep active in hydrocarbon migration and accumulation period connect oil source and reservoirs, and segment vertically growth in Sanzhao depression.
Sustainable Treatment of Oral Traumatic Ulcers with Licorice Containing Hydrogels: Integrating Computational Modeling, Quality by Design, Green Synthesis, and Molecular Biological Evaluation

The urge to implement innovative approaches that align with eco-friendly practices and hold promise for enhancing oral health while promoting environmental sustainability has been increasing. This current work aims to develop a sustainable treatment for oral traumatic ulcers using licorice-based hydrogels (LHGs) containing hydroxyethyl cellulose (HEC) as the green gelling agent. Licorice root aqueous extract was phytochemically profiled using UPLC-ESI-MS/MS. Forty-three compounds were detected, with Glycyrrhizic acid being the major component of the extract (34.85 ± 2.77%). By implementing a Quality by Design (QbD) approach, the study investigates the effects of different licorice extract and HEC concentrations on key variables such as pH and viscosity of the prepared formulations, ulcer and wound healing scores, and tissue growth factors via a Full Factorial Experimental Design. The LHGs exhibited desirable consistency, spreadability, and clarity. Statistical analysis, employing an ANOVA test, revealed the high significance of the constructed models with the licorice concentration being the key independent factor affecting all dependent outputs. The pH as well as the viscosity of the prepared LHGs were positively influenced by licorice extract concentration, with higher concentrations leading to increased alkalinity and viscosity. Rheological behavior analysis revealed a pseudoplastic flow with demonstrated thixotropy which is advantageous for application and prolongation of residence time. The wound healing process was assessed through ulcer size, traumatic ulcer healing score (UHS), collagen-1 expression (COL-1), growth factors (EGF, VEGF), pro-inflammatory markers (TNF-α), wound healing score (WHS). LHGs prepared using higher levels of both factors, 30% dried licorice root extract and 4% HEC, demonstrated enhanced wound healing, elevated growth factor expression of 66.67% and 23.24%, respectively, and 88% reduced inflammation compared to the control group, indicating their potential in expediting oral ulcer recovery. Overall, these findings highlight the promising role of green licorice-based hydrogels in promoting sustainable oral mucosal healing.
Retiolitine graptolites from the Aeronian and lower Telychian (Llandovery, Silurian) of Arctic Canada

Abstract. An exceptional fauna of retiolitine graptolites from Aeronian and lowermost Telychian strata in Arctic Canada provides significant new insights into the phylogeny and history of diversity of retiolitine graptolites. All specimens were isolated by dissolution of calcite concretions. The results indicate that retiolitines emerged within the lower Aeronian and reached a higher than expected level of diversity and disparity of forms by mid-Aeronian time. The uppermost Aeronian is almost totally devoid of preserved graptolites in Arctic Canada and, therefore, our material provides few new insights into retiolitine morphology or diversity through that interval. Specimens assigned to Pseudoretiolites? sp. occur in well-dated lower Aeronian strata, thus representing the lowest known biostratigraphic occurrences of retiolitines globally. This taxon appears to be morphologically primitive in that the sicula is completely preserved, with preservation of the proximal regions of theca 11, as well as distal thecal fusellum on mature specimens. Cladistic analysis of the Llandovery retiolitines shows that Pseudoretiolites is a stem genus for all of the other retiolitine taxa, which comprise two clades: one consisting of Pseudoplegmatograptus, Retiolites, and Stomatograptus and their derivatives; and the other includes Rotaretiolites, Aeroretiolites, Aeroretiolites? , Eorograptus, Paraplectograptus, Paraplectograptus? , and Sokolovograptus, and all of those other taxa that had previously been placed in the Plectograptinae. We follow the recent proposal that all of the taxa traditionally assigned to the Retiolitidae be assigned to the subfamily Retiolitinae. The following new taxa are described: Pseudoretiolites hyrichus n. sp. , Eorograptus spirifer n. sp. , and Aeroretiolites cancellatus n. gen. n. sp.
