AbstractThe objective of the study is to develop and characterize biodegradable monolayer and bilayer films using collagen extracted from tilapia skin and scales (Oreochromis sp.) with chitosan in combination with biodegradable polyester; polylactic acid (PLA) or polycaprolactone (PCL). Collagen extraction was conducted with acetic acid (0.5 M). Monolayer films based on collagen and chitosan were formed by the casting process with a solution of chitosan (2% w/w) in 1.5% acetic acid, followed by the addition of skin collagen at concentrations of 0.5%, 1%, or 2% w/w, and dried at 45–50°C. The PLA and PCL films were made by compression molding. The films were characterized according to their appearance, structure, morphology, interaction with water, thermal stability, and mechanical and barrier properties. The results indicated that collagen from tilapia skin and scales yielded 36.5% and 2.57%, respectively. The results showed that adding chitosan increased the tensile strength but decreased the elongation of the films. An improvement in thermal stability was observed by increasing the proportion of collagen or chitosan, and it also influenced water solubility and water vapor permeability. Microscopy showed a crack‐free interface between collagen and chitosan. The color of the films varied depending on the composition, highlighting the influence of chitosan in yellow and reddish tones. The bilayers with PLA had lower water vapor permeability and higher gloss compared to those with PCL. Finally, the developed films showed promising properties for their application in food packaging and promote the use of fishery waste.Practical applicationsThe study aims to develop and characterize biodegradable monolayer and bilayer films using collagen extracted from tilapia skin and scales (Oreochromis sp.) combined with chitosan and biodegradable polyester such as polylactic acid or polycaprolactone. The practical applications of this research span a wide range of industrial fields. For instance, monolayer films could be used as sustainable food packaging, offering enhanced barrier properties and biodegradability, thus reducing the environmental impact of conventional packaging. Furthermore, bilayer films could find applications in the healthcare industry, such as controlled‐release drug patches or dressings leveraging the antimicrobial properties of chitosan. This research also provides valuable insights into improving the mechanical, thermal, and barrier properties of biodegradable films, potentially leading to the production of more efficient and versatile materials for a variety of industrial applications.
Effect of microwave combined with ultrasonic pretreatment on the flavor of composite stewed soup‐stock

Published: July 2024

AbstractIn order to increase the content of flavoring components and nutrients in the stock, effects of microwave (MW) combined with ultrasonic pretreatment on water‐soluble proteins, flavor nucleotides, volatile gas constituents and sensory evaluation in the stewed stock were explored. The results showed that, compared with the control group (CK), MW, and ultrasonic (US) pretreatment could significantly promote the degradation of nucleotides and form a large number of 5′‐flavor nucleotides. The combined treatment of MW and US promoted protein hydrolysis and increased the content of water‐soluble protein. The microwave combined ultrasonication pretreated stew stock had the brightest color and the overall sensory score was better than that of the CK. In addition, GC–MS analysis showed that a total of 49 volatile substances were detected in the stock samples. After microwave combined ultrasonication pretreatment, the relative contents of aldehydes and alcohols in the stock increased significantly. The sensor response value of the electronic nose was the highest, indicating that the intensity of flavor characteristics increased. Therefore, MW combined with ultrasonic pretreatment can effectively promote the formation and dissolution of nutrients, and increase the content of flavorful nucleotides and volatile gases.Practical applicationThis study provides a novel processing method for traditional stewed stock. Ultrasonic combined with MW treatment can quickly degrade the protein in the raw material and dissolve it into the stock. At the same time, it promotes the formation of flavor nucleotides and accelerates the Maillard reaction to produce more flavor substances. The technology has the advantages of short processing time, environmental protection and safety. It can be used as a potential pretreatment technology to regulate the flavor of stock‐soup.

Published: July 2024

AbstractThe Japanese government's decision to discharge treated water into the ocean has drawn citizens' attention, and the evaluation of this issue remains controversial. The themes underlying social issues are connected to the moral foundation of Haidt's moral foundations theory. Accordingly, these foundations appeal to individuals' subjective approval of their moral foundations. The treated water issue is related to the purity foundation; thus, the present study aimed to investigate the role of the purity foundation on the support for the treated water issue by collecting data from 1,291 Japanese participants immediately after the first discharge of treated water. To measure the purity‐related concept, the Purity Orientation–Pollution Avoidance Scale (POPA) was employed. The results of our multiple regression analysis showed a negative association for the Mental Purity subscale and a positive association for the Respect for Religion subscale of POPA. The different aspects of Japanese purity highlighted by POPA are discussed. This study contributes to a deeper understanding of the mechanisms involved in people's attitudes toward social issues.
Of Birds and Breastfeeding: Augustine and Feminist Concerns about Kenosis
Authors: Komline Han‐luen Kantzer 
Published: July 2024

AbstractThe doctrine of kenosis has kept a low profile in studies of the early church. Yet the biblical idea that Christ “emptied himself” was taken up not only by proponents of kenoticism in the nineteenth century, but also—inevitably—by early Christian thinkers as they interpreted Philippians 2:5‐11, a crucial passage about the identity and spirit of Jesus Christ. Augustine, for example, references kenosis repeatedly across his writings. The notion of kenosis has also been a tenacious thread in the tapestry of feminist theological reflections over the last twenty years. This article weaves these strands together, arguing that three emphases of Augustine's account help to address concerns that feminist theologians have raised: his explication of kenosis as utterly unique and only analogically imitable; his description of kenosis as always additive; and his characterization of kenosis as an irresolvable paradox. This essay develops Augustine's emphases in conversation with recent feminist scholarship—drawing, along the way, on his surprising appeal to the behavior of mother birds and maternal breastfeeding—to suggest some new vantage points for appreciating how the Christian doctrine of kenosis can promote flourishing, for the subject as well as the object of self‐giving love.
Digital twins as a security risk?
Authors: Guikema Seth , Flage Roger 
Published: July 2024

AbstractDigital twins have become a popular and widely used tool for assessing risk and resilience, particularly as they have increased in the fidelity and accuracy of their representation of real‐world systems. Although digital twins provide the ability to experiment on and assess risks to and from a system without damaging the real‐world system, they pose potentially significant security risks. For example, if a digital twin of a power system has sufficient accuracy to allow loss of electrical power service due to a natural hazard to be estimated at the address level with a high degree of accuracy, what prevents someone wishing to lead to disruption at this same building from using the model to solve the inverse problem to determine which parts of the power system should be attacked to maximize the likelihood of loss of service to the target facility? This perspective article discusses the benefits and risks of digital twins and argues that more attention needs to be paid to the risks posed by digital twins.
Testing for time‐varying nonlinear dependence structures: Regime‐switching and local Gaussian correlation

Published: July 2024

AbstractThis paper examines nonlinear and time‐varying dependence structures between a pair of stochastic variables, using a novel approach which combines regime‐switching models and local Gaussian correlation (LGC). We propose an LGC‐based bootstrap test for examining whether the dependence structure between two variables is equal across different regimes. We examine this test in a Monte Carlo study, where it shows good level and power properties. We argue that this approach is more intuitive than competing approaches, typically combining regime‐switching models with copula theory. Furthermore, LGC is a semi‐parametric approach, hence avoids any parametric specification of the dependence structure. We illustrate our approach using financial returns from the US–UK stock markets and the US stock and government bond markets, and provide detailed insight into their dependence structures.

Bounded Spaces – The Enduring Allure of Territorial Identities and the Lasting Value of Paasi's Conceptualisation of the Institutionalisation of Regions
Authors: Mamadouh Virginie 
Published: July 2024

AbstractThis commentary revisits the main elements of Paasi's ideas about the institutionalisation of regions and bounded spaces. It reviews his analysis of the identity of a region and the regional identity of its residents (as addressed in his TESG 2002 article). Next, it discusses how his work on bounded spaces contributed to the reinvention of border studies in political geography and how his innovative conceptual work grounded in and written from Finland, was inspiring for a whole generation of researchers working at the margins of the Anglo‐American academic world. Finally, it reasserts the enduring value of his heuristic framework in a time where the complexity of social spatialisation and of spatial socialisation has greatly increased.

A major challenge facing the Coastal Region of Nigeria is climate change and climate variability. An assessment of the trends and spatial variability of climate, critical for knowledge-based strategies needed for planning adequate mitigation and adaptation measures for the region, requires urgent attention. This study analysed spatial variability and temporary trends of climate change in the Nigeria Coastal Region .. Gridded monthly climatic data from the Climate Research Unit (CRU 0.5 x 0.5) for two climatic periods ((1956- 1986 and 1987-2016) were obtained. Tests for trend detection and magnitude determination utilized: Mann-Kendal and Linear Regression—Thei-Sen Slope test. Climatic maps for rainfall and temperature from 1956 to 2016 for the coastal regions of Nigeria were developed by ordinary kriging. The results from statistical analyses suggest that there is very high rainfall variability with the coefficient of variability (CV) values ranging between 62.43% and 69.46 % and low-temperature variability with CV values ranging between 4.314% and 6.037%. The annual rainfall and temperature increased at the average rate of 3.047 mm yr-1. and 0.0126 oC yr-1 respectively. In 75% of the region, rainfall was decreasing, while in 25%, it was increasing. The implementation of adaptation and mitigation strategies should be mandatory due to the notable increase in temperature.

As an ageing platform has passed its design life of 20 to 30 years, it is crucial to identify wether it is still fit for operation based on the current environmental behaviour, particularly due to the wave impact. Hence, an analytical approach of wave spectrum analysis between the wave behaviour and offshore structural response will be conducted. The aim is to verify the stability and safety of ageing offshore platforms with the current wave behaviour based on identifying wave characteristics, developing a normalized wave energy spectral density, and analyzing the natural frequency of offshore structural response. The methodology includes data collection from structural dynamic monitoring assessments, wave spectrum development using empirical models, and evaluation of offshore platform stability. The results will provide insights into platform stability, resonance risks, and safety assessment of ageing offshore platforms in Malaysian waters. The findings will contribute to recommendations for modifications or improvements to ensure the safety and integrity of offshore platforms in the specific region.

Published: July 2024

Context: To stabilize the humeral head within the glenoid fossa during arm elevation, the rotator cuff muscles may contribute through internal and external rotation. The main purpose of the current study was to compare the acromiohumeral distance between athletes with primary subacromial impingement syndrome who received progressive resistance exercises consisting of either shoulder internal or external rotation. Design: A randomized and controlled clinical study. Methods: Thirty athletes with primary subacromial impingement syndrome were enrolled and randomly divided into 2 experimental groups. The progressive resistance exercise protocol in experimental group I comprised shoulder internal rotation, while in experimental group II consisted of shoulder external rotation. The experimental groups worked out 3 days a week for 6 weeks. The experimental groups were compared with the control group consisting of 15 healthy athletes. The acromiohumeral distance was measured before and after the intervention using an ultrasound machine under the passive and active across no arm elevation and 45°of arm elevation. Results: The acromiohumeral distance significantly increased in both experimental groups under the passive and active arm positions following the intervention (P < .001), with no significant differences detected between the experimental groups (P > .665). The paired comparisons of the acromiohumeral distance discrepancy indicated a significant difference between the control group and each experimental group under the active and passive arm positions (P < .001), while no significant difference was observed between the experimental groups (P > .999). Conclusions: The present study revealed, for the first time, that both progressive resistance exercise protocols involving either the shoulder internal or the external rotation increased the acromiohumeral distance in individuals with primary subacromial impingement syndrome and improved associated pain and disabilities.

Published: July 2024

A chemostratigraphic correlation between the siliciclastic Lower Paleozoic Amdeh Formation outcrops of the Saih Hatat area, just south of Muscat, and the hydrocarbon-bearing Haima Supergroup and Nimr Group of subsurface Oman is presented. The Amdeh Formation is a 3.4 km-thick succession of Cambrian to Ordovician-aged sandstones and shales, divided into five lithological members (Am1–Am5). The Amdeh Formation type section was sampled throughout for inorganic elemental geochemistry, quantitative mineralogy and U–Pb zircon geochronology.
A robust chemostratigraphic framework for the equivalent Haima Supergroup and Nimr Group intervals, defined in the subsurface, is utilized to correlate with the Amdeh Formation. The Amdeh is interpreted to be a basinward, fully marine, time equivalent of the subsurface Haradh (and likely also the Karim), Amin, Miqrat, Al Bashair, Barik, Mabrouk, Barakat, Ghudun and Saih Nihayda formations. This correlation is based on the identification of key mineralogical, depositional, provenance and sequence stratigraphic events within the inorganic geochemical data, guided by outcrop observations of depositional facies and key surfaces, and existing biostratigraphy.
Positioned beyond the northern edge of the Ghaba Salt Basin, the Amdeh Formation outcrops provide important constraints on subsurface reservoir distribution, palaeogeography and basin evolution, factors that are relevant to deep gas prospectivity.
