Characterizing the structure and composition of clay minerals on the surface of Mars is important for reconstructing past aqueous processes and environments. Data from the CheMin X-ray diffraction (XRD) instrument on the Mars Science Laboratory Curiosity rover demonstrate a ubiquitous presence of collapsed smectite (basal spacing of 10 Å) in ~3.6-billion-year-old lacustrine mudstone in Gale crater, except for expanded smectite (basal spacing of 13.5 Å) at the base of the stratigraphic section in a location called Yellowknife Bay. Hypotheses to explain expanded smectite include partial chloritization by Mg(OH)2 or solvation-shell H2O molecules associated with interlayer Mg2+. The objective of this work is to test these hypotheses by measuring partially chloritized and Mg-saturated smectite using laboratory instruments that are analogous to those on Mars rovers and orbiters. This work presents Mars-analog XRD, evolved gas analysis (EGA), and visible/shortwave-infrared (VSWIR) data from three smectite standards that were Mg-saturated and partially and fully chloritized with Mg(OH)2. Laboratory data are compared with XRD and EGA data collected from Yellowknife Bay by the Curiosity rover to examine whether the expanded smectite can be explained by partial chloritization and what this implies about the diagenetic history of Gale crater. Spectral signatures of partial chloritization by hydroxy-Mg are investigated that may allow the identification of partially chloritized smectite in Martian VSWIR reflectance spectra collected from orbit or in situ by the SuperCam instrument suite on the Mars 2020 Perseverance rover. Laboratory XRD and EGA data of partially chloritized saponite are consistent with data collected from Curiosity. The presence of partially chloritized (with Mg(OH)2) saponite in Gale crater suggests brief interactions between diagenetic alkaline Mg2+-bearing fluids and some of the mudstone exposed at Yellowknife Bay, but not in other parts of the stratigraphic section. The location of Yellowknife Bay at the base of the stratigraphic section may explain the presence of alkaline Mg2+-bearing fluids here but not in other areas of Gale crater investigated by Curiosity. Early diagenetic fluids may have had a sufficiently long residence time in a closed system to equilibrate with basaltic minerals, creating an elevated pH, whereas diagenetic environments higher in the section may have been in an open system, therefore preventing fluid pH from becoming alkaline.

With China’s economy transitioning into a post-industrial phase focused on knowledge and technology, there has been a notable shift in the patterns of Chinese Outward foreign direct investment (OFDI). This change has led to the emergence of new research perspectives, underscoring the importance of organizing them systematically. To address this, our research presents a thorough analysis of eighty-eight publications examining Chinese OFDI in natural resource-rich (NRR) and technology-intensive (TI) locations across various global regions and countries. Based on the geographical scope and comprehensive coverage of studies published between 1998 and 2023, we summarize the major themes, theories, and methodologies used in this research area. Identifying three elements related to Chinese investment (antecedents and motives, operational strategies, and investment outcomes), we develop a matrix based on the discussion of Chinese firms’ investment behavior in the foreign environment in which they operate. We describe the theoretical distinctions between investments in NRR global regions, such as Africa and Central Asia, and TI regions, such as Europe and North America, with regard to technology acquisition, creation, co-creation, and transfer. We identify several research sub-themes (e.g., control and learning mechanisms, technology transfer, intellectual property, etc.) that remain under-investigated and suggest future research opportunities.

Over the twentieth century, the Vienna Philharmonic—Austria’s flagship musical institution—became a leading player in global musical life through intercontinental touring, the distribution of recordings, and the establishment of “Austrianness” as a global brand. By framing the mobility of musicians as “world practices,” this article investigates the driving forces behind an Austrian ensemble going global. It understands the Philharmonic’s relation to the music world as an entangled history of globalizing tour destinations, cultural diplomacy, non-European audiences, the agents and interests in the music market, and musical branding. The attitudes that become visible in relation to the musicians’ global mobility and their reluctance to admit non-European players bear witness to the disruptive dimensions of world practices. In conclusion, this article proposes the Philharmonic’s entanglements with Europe, the Americas, East Asia, and the Middle East as an entry point for writing a global history of twentieth-century Austrian culture.

Marine organisms account for more than half of the global biodiversity and have proven to be a rich source of pharmacologically active compounds. Turkey has an extensive coastline hosting a diverse marine ecosystem. This paper describes the phytochemical prospection based on chromatographic profiles of extracts, fractions, and sub-fractions from Turkish organisms. In addition, the samples were evaluated for their antioxidant, anticholinesterasic, and antibacterial activities. According to the chromatographic profiles, terpenes were identified in most samples, with the exception of Dictyonella incisa. Alkaloids were detected in Ascidiella aspersa, Eunicella cavolini, Halocynthia papillosa, Limaria hians, Microcosmus polymorphus, and D. incisa. The phenolic carboxylic acids were detected in all the samples, and the results for polyphenols were similar. The extract of P. clavata showed antioxidant activity in both models evaluated, whereas the remaining samples were positive only in the bioautographic assay. With regard to AChE inhibition, D. incisa fraction showed potent activity (%I ˃ 90%), while the sub- fractions were moderate (%I ˃ 45%). In the antibacterial assay, the same samples from D. incisa have shown activity against both Gram-negative and Gram-positive bacteria. On the other hand, the present study opens up avenues for future research on D. incisa by aligning alkaloids and neuroprotective effects, taking into account that inhibition of AChE is a therapeutic strategy in the treatment of Alzheimer’s disease.

Since the mid-2010s, conflicts at UNESCO over the interpretation of Japanese colonial rule and wartime actions in the first half of the twentieth century in Japan, South Korea, and China have been fierce. Contested nominations include the Meiji Industrial Revolution Sites for the World Heritage List (Japan), the Documents of Nanjing Massacre for the Memory of the World (MoW) Register (China), and two still pending applications on the Documents on the Comfort Women (South Korean and Japanese NGOs). This paper examines the recent “heritage war” negotiations at UNESCO as they unfolded in a changing political, economic, and security environment. Linking World Heritage and MoW nominations together for a holistic analysis, this paper clarifies the interests of State actors and of various non-State actors, such as NGOs, experts, and the UNESCO secretariat. We discuss the prospects for these contested nominations and recommend further involvement of non-State actors to ensure more constructive and inclusive heritage interpretation to enable a more comprehensive understanding of history.

The study investigated the effects of replacing maize with enzyme-supplemented Dried Date Fruit Pulp (DDFP) in the diets of broiler chickens. 576-day-old commercial broiler chicks (Arbor Acre Plus) were randomly selected and distributed into 8 treatment groups of 72 birds each. Each treatment was divided into six replicates of 12 birds on a weight-equalisation basis. The treatments consisted of 4 levels of DDFP (0, 100, 200 and 300 g/kg) and 2 levels of enzyme supplementation (with or without). The data obtained were subjected to an Analysis of Variance in a 4 × 2 factorial arrangement. Birds fed 300 g/kg DDFP recorded the least weight gain (971 g) and final weight (1013 g) across the treatments at the starter phase, while there were no significant (P > 0.05) differences in the final weight, weight gain, feed intake and feed conversion ratio of birds fed with DDFP and maize-based diets at the finisher phase. DDFP inclusion reduced the experimental birds’ feeding cost (NGN/kg) and cost/kg weight gain (NGN/kg WG). Enzyme supplementation increased serum protein and glucose concentrations. Reduced (P < 0.05) EE and CF digestibility coefficients were seen in birds fed 30% DDFP at the finisher phase. Carcass indices, ileal digesta viscosity and caecal total bacteria were not negatively influenced. It was concluded that DDFP could replace up to 200 g/kg maize in broiler chicken diets at the starter phase and up to 300 g/kg at the finisher phase without any deleterious effects on health and performance.

Five specimens of the rare alpheid shrimp Betaeus levifrons Vinogradov, 1950 were collected from the burrows of the mud-shrimp Upogebia major (De Haan, 1841) in Akkeshi and Usu Bays, along the Pacific coast of Hokkaido, Japan. As B. levifrons has been previously only reported from the Russian coast of the Sea of Japan, the Hokkaido specimens represent the first record of this species from the western Pacific coast as well as a new to the Japanese fauna. Ovigerous females of B. levifrons were recorded for the first time based on specimens. This study provides additional data on this species, including its distribution, colour variation, and DNA sequences of the mitochondrial 16S rRNA and cytochrome c oxidase subunit I barcoding regions. Lastly, we revised the available data on the symbiotic fauna of U. major.

This review highlights the importance of dietary fibres (DF) intake and its interconnection with the gut microbiome and psychological well-being, while also exploring the effects of existing DF interventions on these aspects in adults. The gut microbiota is a complex and diverse ecosystem in which microbial species interact, influencing the human host. DF are heterogeneous, requiring different microbial species to degrade the complex DF structures. Emerging evidence suggests that microbial fermentation of DF produces short-chain fatty acids (SCFA), which may play a role in regulating psychological well-being by affecting neurotransmitter levels, including serotonin. The effectiveness of DF interventions depends on factors such as baseline gut microbiota composition, the dosage and the source of DF consumed. Although the gut microbiota of adults is relatively stable, studies have shown that the abundance of the species in the gut microbiota can change within 24 h of an intervention and may return to baseline following the termination of DF intervention. This review underscores the need for larger and well-powered dietary clinical trials incorporating longitudinal biological sample collections, advanced sequencing and omic techniques (including novel dietary biomarkers and microbial metabolites), validated subjective questionnaires and dietary records. Furthermore, mechanistic studies driven by clinical observations are crucial to understanding gut microbiota function and its underlying biological pathways, informing targeted dietary interventions.

There has been a renewed focus on improving mental health outcomes and experiences for women with the publication of ‘Embedding Women’s Mental Health in Sharing the Vision’, but much needs to be done to translate this policy into tangible improvements in delivered care. Historical biases in medical education and practice, as well as in research, have led to serious deficiencies in how illnesses are diagnosed and managed in women. This is not solely observed in mental health, and andronormative perspectives and gender blindness are widespread throughout medicine. Trauma informed practices should be adopted in all healthcare settings that treat women. Consideration also needs to be given to reproductive life stage in psychotropic prescribing beyond concerns of the risk of teratogenicity. Medical education and training should play a central role in increasing gender awareness among healthcare professionals. Combining top-down policy initiatives with bottom-up education and training is required to meaningfully integrate gender awareness into mental healthcare and address historical shortcomings in care for women. Implementing gender-sensitive practices is an important step toward delivering more individualised, patient-centred mental health services.

We analyze the effects of different pay-as-you-go public pension systems on financial imbalance, rate of return, and inequality of heterogeneous generations in terms of gender and education. We include aspects that are relevant for developing countries such as labor informality and payment of an old-age and social benefit. We introduce a new mixed system that combines components of the defined benefit (DB) and the defined contribution (DC) systems. Results show the new mixed system represents a compromise between the DB and DC systems and that a scheme (inspired in the German system) exhibits the highest rates of return and horizontal equity.

This article contends that the humanitarianism that developed in Europe in the 1930s and 1940s and, in particular, because of the Spanish Civil War, was shaped by a transnational network that was fundamentally female. Within this network, women with diverse political experiences converged; however, suffragism, pacifism and anti-fascism occupied a central place. Humanitarianism became for them a favourable space from which to intervene politically. To demonstrate this, we focus on the CAEERF, an aid organisation formed in 1939 in response to the arrival of Spanish refugees in France. It was created, led by and composed mainly of women from different backgrounds. The first part of this article concerns anti-fascist and humanitarian women’s networks that emerged during the Spanish Civil War. The second traces the journey of the British Quaker Edith Mary Pye, the driving force behind the CAEERF. The third and fourth parts discuss its creation and the work that it carried out on the ground.

Metarhizium guizhouense (Clavicipitaceae) is an insect pathogen employed as a mycoinsecticide against many insect pests worldwide. In this study, for the first time in a laboratory setting, the pathogenicity of the M. guizhouense isolate PSUM04 was evaluated against the coffee berry borer, Hypothenemus hampei (Coleoptera: Curculionidae: Scolytinae). Following the exposure (1 × 109 spores/mL) of H. hampei to M. guizhouense PSUM04, morpho-histopathological changes and numbers of apoptotic cells via the TUNEL (terminal deoxynucleotidyl transferase (TdT), dUTP (deoxyuridine triphosphate) nick-end labelling) assay in H. hampei were evaluated at 12-hour intervals until 144 hours after exposure. The external morphology of H. hampei underwent drastic changes from 24 to 144 hours post-exposure accompanied by the degeneration of integument and adipose tissues. The semi-quantitative analytical score of TUNEL-positive cells showed a slight increase at 12 hours after exposure and a significant increase in TUNEL-positive apoptotic cells at 48 hours after exposure. These results suggest a series of tissue alterations of H. hampei during its process of infection with a strain of M. guizhouense, highlighting the pathogen’s potential as a biological control agent in natural settings.
