Eurocentrism and the constraints in alternative knowledge production: the case of Pakistani international relations

This article addresses the persistent Eurocentrism in the national IR academies within the Global South, notwithstanding continued appeals for pluralization of the global field of IR. Focusing on the discipline of IR in Pakistan, the study explores the implications of Western intellectual dominance through in-depth interviews with local IR academics. The findings demonstrate a marked dependence on realist ideas (the classical strand in particular), which emphasize state-centric and security-focused views of world politics. This restricted approach corresponds with realpolitik because of its pragmatic focus on state security and interests, while ignoring broader theoretical assumptions. These realist ideas are sustained through academic norms, establishing a pattern which perpetuates Eurocentric perspectives in the Pakistani IR community. The article recognizes Western intellectual gatekeeping practices, and the national higher education system of Pakistan, as notable hindrances to the advancement of the discipline in Pakistan. Additionally, lax academic standards in local knowledge production, tied to professional progression, confine Pakistani IR academics to domestic publishing platforms. This discursive environment incentivizes state and security-oriented research, leading to IR scholarship in Pakistan that lacks originality and quality, remains predominantly Eurocentric, and primarily supports state security policies. The study underscores the necessity for a more diverse and contextually relevant approach to IR in Pakistan, which would better capture the country’s unique realities and contribute to a richer global discourse.

First report of Curvularia chiangmaiensis causing leaf spot in elephant grass in Brazil.

Elephant grass, Cenchrus purpureus, exhibits high efficiency in sequesting atmospheric CO2 during photosynthesis, leading to significant biomass production. As a C4 plant, it holds immense potential for alternative biodiesel production and serves as fresh feed for cattle (Negawo et al. 2018). Field observations in commercial pastures planted with elephant grass, located in the Brazilian cerrado, revealed necrotic leaf spots with a brownish center and a yellowish halo, reaching a severity of 30 to 50% between 2022 and 2023 in Palmas (10°24'08"S 48°21'45" W) and Gurupi (11°46'21"S 49°02'08" W), municipalities located in the state of Tocantins, Brazil. In both years, the field incidence of the disease on young and mature leaves approached 100% during the rainy season. Affected leaves were collected, packed in a thermal box, and taken to the phytopathology laboratory. The 198 leaves were sanitised in 1% hypochlorite for 30 seconds and washed thrice in sterile water. Upon sanitisation, leaf tissues were cut and cultured on potato dextrose agar (PDA) medium and incubated in a controlled chamber (BOD) at 28°C with a 12-hour photoperiod. Colonies exhibited a greyish colour with whitish edges, and the top plate was brownish, growing to a diameter of 5 cm over seven days. The colonies obtained from monosporic cultures formed curved conidia, predominantly with three septa, of a brownish colour, with lengths ranging from (7 µm to 14 µm and widths from 5 µm to 7 µm. (N=-50, Fig 1) (Yasanthika et al. 2023). The UFTCC01 isolate's DNA was extracted using the extraction kit (PROMEGA ®), amplified for genes (ITS, Gapdh and Tefα1), sequenced (OR345316.1, OR344427.1 and OR344428.1) and compared in BLASTn at Gen Bank deposited sequences. Phylogenetic analysis using the parsimony method in MEGA X identified the isolate as Curvularia chiangmaiensis, showing 99.5% identity with reference sequences (MN215651.1, MN264085.1, and MN263942.1). Concatenated region comparison revealed 94% similarity to sequences (OP564987.1 and MF490814.1) in the phylogenetic tree, confirming the species. The pathogenicity test used 60 seedlings of 50-day-old elephant grass, 30 of which were inoculated with a spore suspension (3.0 × 106 spores/mL) and 30 with sterile water. The solutions were sprayed twice. Only plants inoculated with the spore suspension exhibited symptoms akin to those observed in the field. Then, the fungus was reisolated from the lesions and Koch's postulates were confirmed twice.Previous studies have documented the C. chiangmaiensis pathogenicity in other grasses, such as maise in Thailand (Marin et al. 2017). Our studies constitute the first report of C. chiangmaiensis causing leaf spots on elephant grass in the Brazil.

Structure and Function of Sabinene Synthase, a Monoterpene Cyclase That Generates a Highly Strained [3.1.0] Bicyclic Product.

Sabinene is a plant natural product with a distinctive strained [3.1.0] bicyclic ring system that is used commercially as a spicy and pine-like fragrance with citrus undertones. This unusual monoterpene has also been studied as an antifungal and anti-inflammatory agent as well as a next-generation biofuel. In order to understand the molecular determinants of [3.1.0] bicyclic ring formation in sabinene biosynthesis, we now report three X-ray crystal structures of sabinene synthase from Western red cedar, Thuja plicata (TpSS), with open and partially closed active site conformations at 2.21-2.72 Å resolution. We additionally report the complete biochemical characterization of sabinene synthase, including steady-state kinetics, active site mutagenesis, and product array profiling. The catalytic metal ion requirement is unexpectedly broad for a class I terpene cyclase: optimal catalytic activity was measured using Mn2+ or Co2+, with more modest activity observed using Mg2+ or Ni2+. Kinetic parameters were determined for both full-length TpSS and a deletion variant lacking the putative N-terminal plastidial targeting sequence, designated ΔTpSS. Monoterpene product profiles for both indicated similar product arrays independent of the catalytic metal ion used, with sabinene comprising nearly 90% of the total products generated. Site-directed mutagenesis was utilized to probe the function of active site residues, and several mutants yielded altered product arrays. Most notably, the G458A substitution converted ΔTpSS into a high-activity α-pinene synthase. α-Pinene contains a bicyclic [3.1.1] ring system; structural and mechanistic analyses suggest a molecular rationale for the reprogrammed transannulation reaction, leading to the alternative bicyclic product.

Inhibition of the Growth of Four Phytopathogenic Fungi by Eucalyptus Wood Vinegar

Purpose: The objective of this work aimed to assess the wood vinegar (WV) from the carbonization of Eucalyptus wood in the inhibition in vitro of Fusarium sp., Ganoderma sp., Macrophomina sp., and Sclerotium rolfsii. Method: WV was added to a culture medium and poured onto Petri dishes. After, the fungi were picked up in 1-mm disks and placed in the center of each Petri dish. The experimental design had five treatments, T1, T2, T3, T4, and T5, with crescent concentrations of WV, respectively, 0 (control), 5, 10, 15, and 20 mL L-1. The variables evaluated were fungal growth, mycelial growth rate index, and percentage of mycelial growth inhibition. Results and Discussion: A gradual decrease in the mycelial growth, in the mycelial growth rate index, and an increase in the percentage of mycelial growth inhibition were determined for all assessed fungi in the concentration of 20 mL L-1 of WV. Hence, the conclusion was that eucalyptus WV presented fungi-toxic properties over the assessed fungi and the product can be considered as an alternative for the chemical control of the incidence of these pathogens in crops and forest plantations. Research Implications: The use of natural products with fungi toxic properties is becoming important for the control of pathogens that attack crops and forest plantations due to the harmful effects of the conventional fungicides on living organisms and the environment. The search for efficient alternative products is therefore a goal to be reached in the field of phytopathology. Originality/ Value: The use of natural products with fungitoxic properties has been gaining ground in the control of pathogens affecting agricultural and forestry crops. This intensifies the search for natural products that are efficient in the biocontrol of phytopathologies.

Antimicrobial Impact of Wood Vinegar Produced Through Co-Pyrolysis of Eucalyptus Wood and Aromatic Herbs

Background: The search for substances that can overcome microorganisms’ resistance and enhance the antimicrobial activity of given products has attracted the attention of researchers. Eucalyptus wood vinegar (WV) is a promising product for developing alternative antimicrobials. Objectives: This study aimed to evaluate whether the production of WV in the co-pyrolysis of eucalyptus wood with aromatic herbs would incorporate compounds from them into WV and if that would enhance its antimicrobial action. Methodology: WV was produced alone and through co-pyrolysis with marjoram (Origanum majorana), Peruvian oregano (Origanum vulgare), rosemary (Salvia rosmarinus), thyme (Thymus vulgaris), and Turkish oregano (Origanum onites) at a proportion of 25% of herbs to the bone-dry wood weight. The antimicrobial effects were assessed against strains of gram-negative and -positive bacteria, and Candida glabrata. Microorganisms’ colony growth in agar had their absorbances recorded after inoculation and incubation. Chemical characterization of the new products was performed by gas chromatography and mass spectrometry (GC/MS). Results: After coproduction, there were relevant chemical changes concerning the original WV. Thymol, for instance, was incorporated into the WV through co-pyrolysis with marjoram, Peruvian and Turkish oregano, and thyme. The coproducts were more efficient than the WV produced only with wood, with thyme-incorporated products having the highest efficiency. This can be attributed to the increase and incorporation of the substances after coproduction, and particularly the role of thymol in enhancing the antimicrobial action. Conclusion: Given the results, the co-production of WV with eucalyptus wood and aromatic herbs has the potential to provide alternative antimicrobial products.

Russian exports amid geopolitical instability: The case of physical and transitional climate risks

The paper examines the impact of physical and transitional climate risks, which to some extend shape the geopolitical situation in the world, on Russian exports. The gravity model of international trade was employed to model the existing relationship. Estimation of the gravity equation by means of the Poisson Pseudo Maximum Likelihood (PPML) method using data on Russian export flows to 72 countries over the period 2010—2021 revealed that climate change and the ambitions of trading partner states towards low-carbon development determine the dynamics of Russian exports. In particular, national physical climate risks have a detrimental impact on Russia’s exports due to the destruction of infrastructure, loss of capital, reduced quality and availability of natural resources, and increased social tensions. Extreme climatic events and climate change measures in trading partner countries spur the development of Russian exports. Namely, physical climate risks of importing countries may increase the demand for key Russian goods for economic recovery purposes. Changes during the transition to a low-carbon economy in trading partner countries also generate opportunities for Russian export growth due to the country’s role as a major supplier of energy and mineral products, as well as technologies for the alternative energy production and electrification of transport

Antioxidant Properties of Freeze Dried Mix Fruits and Vegetables Product ‘Miss Freezy’ Using Lyophilization Method

Background: The proper processing of fruits and vegetable-based food products will improve appearance, taste, bioactivities, and preservation. Freeze-dried (FD) or lyophilization of foods extends shelf life and preserves food's nutritional value and bioactivities. The objective of this study is to compare the antioxidant properties, nutritional value, and vitamins of fresh fruit-vegetables and the combined FD product. Methods: A combination of fruits (mango, papaya, star-fruit, guava, banana, bengkuang), and vegetables (cucumber), called “Miss Freezy” were cleaned with an ozonizer and processed using the lyophilization method. The antioxidant activities measured included 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS), 2,2-Diphenyl-1-picrylhydrazyl (DPPH), and Hydrogen Peroxide (H2O2) assay. While the proximate analysis measured was the determination of water content, ash content, fat content, protein and carbohydrate content, and vitamin C. Results: The value of antioxidant activity in fruit-vegetable combination FD products was higher than in fresh fruit. The median inhibition concentration (IC50) of DPPH, ABTS, and H2O2 scavenging activities were guava 48.74 µg/ml, guava 128.39 µg/ml, and banana 155.55 µg/ml, respectively. The results showed that the water content of fresh fruits, and vegetables was greater than FD products and inversely proportional to the level of ash, fat, protein, carbohydrates, and vitamin C lower than FD products. Conclusions: Based on the results of antioxidant activities, proximate analysis and vitamin C of the FD product was higher than fresh fruits and vegetables. The FD fruit-vegetable combination product can be used as an alternative snack product that is practical and healthy.

Microbiological quality of plant-based meat-alternative products collected at retail level in Switzerland.

As the interest in plant-based alternative food products has increased significantly in the last years, it is also important to investigate these products regarding microbiological aspects. The aim of this study was to assess the microbiological quality and the occurrence of selected foodborne pathogens in plant-based meat alternative products (PBMA) collected at retail level in Switzerland. A total of 100 PBMA (84 vegan and 16 vegetarian products) was analyzed qualitatively for the presence of Salmonella, Listeria monocytogenes and quantitatively for Staphylococcus aureus, Bacillus cereus group members, Enterobacteriaceae and the total viable count. Furthermore, pH measurements were carried out and the aw-value was determined. Isolates were further analyzed with Whole Genome Sequencing. The total viable count before the expiration date was between < 2 log and 7 log CFU/g (median: 5.97 log CFU/g). In six (6 %) samples Enterobacteriaceae with 2 log to 3 log CFU/g were detected. No Salmonella and no Listeria monocytogenes were detected. However, seven products (7 %) were contaminated with other Listeria spp. (six L. innocua and one L. seeligeri). Further findings were two (2 %) Staphylococcus aureus ST8 with the presence of selx and tsst-1 genes, and five (5 %) Bacillus cereus group members (three B. paranthracis, one B. cereus sensu stricto, and one B. cytotoxicus) which all were diarrhea-associated strains. This study provides data that are relevant for HACCP concepts of companies that produce plant-based meat alternative products and helps to define microbiological parameters that should be included when testing such products.

The socioeconomic dimension of forest therapy: A contribution to human well-being and sustainable forest management

Forests provide a variety of ecosystem services that contribute in various ways to human well-being. In times of land-use pressures, urbanisation, and nature degradation, the societal demand for forest-based therapeutic uses is increasing. Although nature-related therapies and the beneficial effects of nature on health and well-being are an old concept in cultures such as Asia and, more recently, Europe, forest therapy offers are increasingly taking hold in the forest recreation landscape. This Commentary paper identifies recent forest therapy offers and research in Asia and Europe that focus on the therapeutic effects of forests and examine their underlying rationales, practices, and status. In particular, we elaborate the socioeconomic potential of forest therapy to contribute to human health and sustainable forest management. Based on a scoping review on forest therapy offers and research, we found that countries such as Japan and South Korea are ahead of European countries in the professionalization of forest therapy offers and respective studies. While the number of studies that demonstrate the positive health benefits of forests are increasing, there is a lack of understanding the link with forest management approaches and forest and health policies. A lack of socioeconomic evaluation hinders its successful integration into policy frameworks, and prevents its use as an alternative forestry product or preventive medical treatment. For forest therapy to become part of the forestry portfolio and a medical alternative, we recommend:•Interdisciplinary research approaches and new actor alliances that link societal demands for forest therapy with insights from forest management and medical health research,•Transdisciplinary research and multi-actor approaches to link insights from forest and medical research with practitioners’ skills for forest management, service design, and communication,•To identify trade-offs and conflict potentials with forest therapy, for example in relation to timber production or questions of insurance in case of injuries by falling branches etc., that allow to develop integrated and sustainable solutions,•Policy backup and economic support for forest managers and owners to compensate for their efforts to manage their forests for therapeutic purposes•Recognition of forest therapy as an explicit part of the forestry portfolio and an alternative medical offer for clinical treatments.

Friends and Foes: Bacteria of the Hydroponic Plant Microbiome.

Hydroponic greenhouses and vertical farms provide an alternative crop production strategy in regions that experience low temperatures, suboptimal sunlight, or inadequate soil quality. However, hydroponic systems are soilless and, therefore, have vastly different bacterial microbiota than plants grown in soil. This review highlights some of the most prevalent plant growth-promoting bacteria (PGPB) and destructive phytopathogenic bacteria that dominate hydroponic systems. A complete understanding of which bacteria increase hydroponic crop yields and ways to mitigate crop loss from disease are critical to advancing microbiome research. The section focussing on plant growth-promoting bacteria highlights putative biological pathways for growth promotion and evidence of increased crop productivity in hydroponic systems by these organisms. Seven genera are examined in detail, including Pseudomonas, Bacillus, Azospirillum, Azotobacter, Rhizobium, Paenibacillus, and Paraburkholderia. In contrast, the review of hydroponic phytopathogens explores the mechanisms of disease, studies of disease incidence in greenhouse crops, and disease control strategies. Economically relevant diseases caused by Xanthomonas, Erwinia, Agrobacterium, Ralstonia, Clavibacter, Pectobacterium, and Pseudomonas are discussed. The conditions that make Pseudomonas both a friend and a foe, depending on the species, environment, and gene expression, provide insights into the complexity of plant-bacterial interactions. By amalgamating information on both beneficial and pathogenic bacteria in hydroponics, researchers and greenhouse growers can be better informed on how bacteria impact modern crop production systems.

수학 학습 촉진을 위한 애니메이션 자료 제작 연구: 파이썬 라이브러리 Manim을 기반으로

Objectives The purpose of this study is to propose guidelines for producing animation materials as a way to help students understand the characteristics of mathematics and mathematical concepts and principles, and to in-troduce Manim, an effective mathematics animation material production tool. Methods We investigated animation production principles that can be helpful in the math animation production process, and applied them to already produced math animation materials to find out their suitability as math ani-mation production principles. In addition, the scope of GeoGebra's animation implementation functions, which are used in the production of mathematical materials, was confirmed, and the possibilities of supplementing the limi-tations of various functions revealed here were explored through Manim. and we looked at the process of produc-ing animation materials using Manim and the results. Results As a result of analyzing whether the animation production principles adopted and applied are valid for the production of mathematics animation materials, we found some requirements that should be modified and sup-plemented from the perspective of mathematics education, and derived improved guidelines for the production of mathematics animation materials. GeoGebra, one of the production tools, has an animation composition func-tion, but there were limitations in its implementation functions, such as setting text condition input and repeating the target hiding operation. In comparison, although Manim requires an understanding of basic Python grammar, it was found to have great advantages in producing mathematical animation materials, such as intuitive com-mands, convenient property change function, free expression ordering, and various animation effects. Conclusions Previous animation production research has not sufficiently considered the abstract nature of math concepts. accordingly, the need for improved guidelines that cover the expression of mathematical concepts, and the use of formulas as the main object of animation has emerged. GeoGebra has limitations in its animation com-position function, so the need for it is increasing along with the expansion of new mathematical animation material creation tools that go beyond that function. accordingly, it was confirmed that Manim, which uses simple com-mands as an alternative production tool, is a very specialized tool for creating mathematical animations.

Lifestyle habits and openness to alternative tobacco products: insights from the Minerva Project

Abstract Background Recent studies have suggested that the use of alternative tobacco products (ATPs) is a significant predictor of cigarette smoking, particularly among young individuals. The present study evaluates the association between dietary patterns, specifically junk food consumption, and the willingness to try ATPs among non-smokers. Methods MINERVA (My changINg lifEstyles, our Research, and eVeryone’s heAlth) is an ongoing prospective international cohort study primarily focused on investigating the link between smoking habits and the dietary and lifestyle habits of participants. Subjects are given a web-based survey to report socio-demographic characteristics, dietary and lifestyle habits, smoking habits, and attitudes towards ATPs. This analysis concentrates on respondents from Italy who do not smoke traditional tobacco products. Results The survey included 7,535 respondents from Italy; of these, 40% (2,992 subjects) were non-smokers. Among the non-smokers, 219 (7%) were identified as fast-food consumers (defined as consuming fast-food at least once a week). Fast-food consumers were significantly more likely to consume junk food as snacks (87% vs. 62%) and were less likely to report daily consumption of fruits and vegetables. Notably, fast-food consumers were 2.5 times more likely to be willing to try ATPs compared to those who do not consume junk food (Odds Ratio [OR] 2.55, 95% Confidence Interval [CI] 1.68-3.88). Conclusions Junk food consumption has been identified as being associated with an increased willingness to use ATPs among non-smokers. This finding is significant from a public health standpoint, highlighting the crucial influence of unhealthy eating habits in fostering an interest in ATP use. Key messages • The Minerva study evaluates the association between dietary patterns, specifically junk food consumption, and the willingness to try alternative tobacco products among non-smokers. • The study underscores the public health importance of addressing dietary patterns alongside smoking habits.

Exploitation of Biobased Co-Product Streams; Contributing to European Protein Demands Using Ethanol Plant Derived Co-Products

Abstract Europe is short of high-quality protein for animal feed, being only 29% self-sufficient in high-quality protein and relies heavily on imported proteins. But consumer demand is shifting towards more sustainable, home-grown sources of plant-based protein. This presents a significant challenge for the animal feed industry. Establishing a new plant protein crop for Europe would take a decade to create elite, geographically adapted varieties, adopt new agronomic practices, and establish appropriate supply chains. Approximately 9 million tons of European non-GM grains (maize, wheat, barley and rye) are converted annually by fermentation into bioethanol, a renewable fuel. The residue of the grain is currently used as medium-quality protein animal feed (distillers dried grains and solubles (DDGS; approx. 30% crude protein). Mechanically processing to separate the protein from the fibre fraction produces a Super-Pro (&gt;50%crude protein concentration). The process produces commercially viable quantities of high-quality, non-GM grain protein, that can be used as an alternative to imported soybean products, in a time frame significantly ahead of establishing alternative agronomies or developing alternative novel proteins. Processing technology can transform low-quality co-product steams into high-quality alternative animal feed products and merits further investigation as a means of producing sustainable animal feed. Re-engineering grain bioethanol plants into biorefineries allows them to produce a super high protein (&gt;50% crude protein) feed material concurrently with bioethanol, a renewable fuel.

Level of tobacco dependence and beliefs towards heated tobacco products

Abstract Nicotine dependence affects not only behaviors related directly to smoking, quit attempts or looking for alternative products but also beliefs about smoking. We sought to assess whether the level of tobacco dependence is associated with beliefs and feelings towards heated tobacco products (HTP) and to assess the relationship between tobacco dependence and the motivators to quit HTP use. Random population sample of Polish citizens aged 18+ years, former smokers, current HTP users was recruited. Tobacco dependence was assessed using 5 question; participants were classified into two groups of tobacco dependence (low or high) using a two-stage cluster analysis. An extensive questionnaire on beliefs on HTP use was administered. The χ2 test and logistic regression were used. There were 2,500 participants (62.6% women) of median age=36 years (Q1=29, Q3=45). The median number of years of smoking was 10 (Q1=5, Q3=15) and median number of years of HTP use was 2 (Q1=1, Q3=3). High tobacco dependence was found in 958 (38,3%) participants. Compared to low dependence, high tobacco dependence was related with feeling of strong need for HTP use (69.7% vs. 47.6%, p &amp;lt; 0,001). High level of tobacco dependence was positively related to perceived social pressure against smoking (72.9% vs. 44.9%, p &amp;lt; 0,001), but it did not differentiate perceived social pressure against HTP use. Compared to low tobacco dependence, participants with high tobacco dependence more often indicated fear of illness OR = 1,73 95%CI=1,46-2,07, own resolution OR = 1,32 95%CI =1,12-1,55 and price OR = 1,34 95%CI=1,13-1,59 as possible motivators to quit HTP use. Level of tobacco dependence in former smokers shaped beliefs and feelings towards HTP use. High tobacco dependence contributed to strong need to use HTP and also increased perception of social pressure against smoking, but not against using HTP. It also increased the importance of fear of illness, price and one’s own resolution as motivators to quit HTP use. Key messages • High level of tobacco dependence in former smokers results in stronger perceived social pressure against smoking but not against HTP use. • High tobacco dependence in former smokers is related with stronger need to use HTP.

Productive, Physiological, and Environmental Implications of Reducing Crude Protein Content in Swine Diets: A Review.

Pig production is one of the most important providers of high-quality proteins and amino acids (AAs) to human nutrition. In this sector, feeding has an important economic and environmental impact. A strategy to reduce production costs and negative sustainability effects is reducing dietary crude protein (CP) contents with or without AA supplementation. This review addresses the different aspects related to this strategy, particularly the effects on growth performance and pork traits in piglets and growing and finishing pigs, as well as the physiological molecular mechanisms' underlying effects. Insight is also provided into the effects of dietary CP reduction on the productive performances of alternative pig production systems and breeding boars and sows. Finally, an overview is conducted on the effects of dietary CP reduction on ammonia, odor, and greenhouse gas emissions arising from pig production systems. Overall, CP reduction may lead to production losses, albeit they can be, to some extent, hindered by adequate AA supplementation. Losses are particularly relevant during the post-weaning phase, whereas in finishing pigs, it may bring additional benefits, such as high intramuscular fat contents in some markets or improved gut barrier function with benefits to the animals' health and welfare, as well as decreased ammonia emissions to the environment.

Reshaping Sports Journalism Through Innovation: An Analysis of L’Équipe Explore’s Strategies, Practices and Output

ABSTRACT Sports journalism practice faces important challenges deriving from the multiplication of platforms, the acceleration of workflows, the emergence of new entrants and the audiences’ shifting consumption habits. In a bid to overcome those challenges and advance innovation across the board, the French newspaper L’Équipe established a specific unit for that purpose: Explore. By focusing on this case study, this research has examined the formats, output and practices deployed by Explore and evaluated its impact within L’Équipe’s offer. The study is informed by content analysis performed on the projects (N = 201) published by Explore over a 32-month timeframe (May 2021–December 2023), ethnographic work and eight semi-structured interviews with its employees. Findings reveal that Explore stands out as a leading “media lab” in sports journalism. Through a broad range of formats and a multifaceted agenda, Explore occupies a unique position in terms of delivering cultural capital. Explore embraces alternative production modes that invest in freedom and research while rejecting hyper-accelerated cycles and clickbait-oriented approaches. Such proposition has resonated with audiences and positioned Explore as a cornerstone of L’Équipe’s commercial strategy. Solutions articulated by Explore contribute to the broader discussion of how sports journalism practice can be reshaped in the digital age.

Ferrates (VI) ; Alternative products in water treatment : their electrochemical synthesis

This study focuses on determining the optimum conditions for the electrochemical generation of ferrates in concentrated NaOH solution. Various operating parameters, including electrolyte concentration, current density, temperature, electrolysis duration, and the composition and form of the anode, were investigated to enhance the yield of electrochemical ferrate (VI) ion production. The synthesized ferrates were characterized using UV-visible and FTIR spectroscopic techniques. Experimental results confirmed the formation of ferrate ions, with optimal synthesis conditions identified as follows: a current density of 11.96 mA/cm², NaOH concentration of 16 M, electrolysis time of 1 hour, temperature of 25°C, and the use of white cast iron as the anode material. These conditions were found to yield the highest efficiency for sodium ferrate production. The spectroscopic analysis effectively verified the presence of ferrate (VI) ions, providing valuable insights into the electrochemical synthesis process. This study contributes to the advancement of ferrate synthesis techniques, potentially offering an efficient route for large-scale production.

Greenhouse gas emissions and net energy production of dark fermentation from food waste followed by anaerobic digestion

There are diverse estimations regarding the carbon reduction effects of alternative hydrogen production technologies. This study assessed the greenhouse gas (GHG) emissions and energy balance of a two-stage process combining dark fermentative hydrogen production and anaerobic digestion from food waste using the cradle-to-gate life cycle assessment (LCA). The system boundary included collection and transportation, pretreatment and feedstock storage, dark fermentation, H2 purification, anaerobic digestion and heat and power generation and the estimated GHG emission was compared with a single anaerobic digestion of food waste. GHG emission of the biohydrogen production was estimated as 2.48 kg CO₂-eq per kg H₂ without considering avoided emissions from heat and power generation. The environmental impacts were majorly influenced by electricity use. The net energy ratio of the two-stage process was calculated to be 8.18, confirming a net energy gain and the potential GHG emission avoidance for electricity and heat use. Given that the single-stage anaerobic digestion of 16 tons of food waste is replaced by the two-stage dark fermentation process, 76.6 kg CO₂-eq would be avoided. Sensitivity analysis revealed that energy-saving strategies are the most sensitive factors for achieving positive net energy production and low global warming potential.

Agroecological farmer perceptions and opinions towards pest management and biodiversity in the Argentine Pampa region

ABSTRACT Agroecology has recently become an alternative production model that tries to face the negative environmental and socioeconomic consequences of the agricultural model based on excessive agrochemical use and no-tillage practices. It searches for alternatives to pest management so as to increase yields while promoting biodiversity conservation. Our goal was to know the perception and opinion of agroecological farmers of the Pampa region on crop pests, the techniques they use for pest management and their perceptions on biodiversity. A survey was conducted which provided 103 responses. The main pest mentioned was ants. Of farmers surveyed, 64.71% claim that their main pest significantly reduces their yields, 79.42% claim that they monitor their crops for pests, although those with over 25 years of experience tend not to. Farmers have a mostly positive perception of biodiversity, particularly birds even though many identify pigeons and parrots as damaging. These results make it possible to describe the agroecological Pampa farmers and to show some common pest issues that need to be observed to benefit production in the area. The study highlights the importance of biodiversity for these farmers and their willingness to use tools that attract birds that could potentially manage pests.

Boosting electrochemical ammonia synthesis via dynamic nitrogen carriers coupled with electron-rich Lewis acidic sites on TiO2−x nanofiber

In light of the high energy consumption and substantial carbon emissions associated with traditional NH3 production based on the Haber–Bosch process, the aqueous electrochemical nitrogen reduction reaction (NRR) offers a clean and sustainable alternative production route. Nevertheless, activating the NN bonds at room temperature is challenging due to the high bond energy, severely hindering the development and commercialization of the electrochemical NRR. Herein, we report a synergistic strategy for achieving efficient N2 activation at ambient conditions that combines electrolyte engineering with catalytic site-modulated TiO2−x nanofiber electrocatalysts. The synthesized TiO2−x nanofiber electrocatalysts contained abundant intrinsic oxygen vacancies and were further modified with hydroxyl groups to create electron-rich Lewis acidic Ti sites. Additionally, BF3 was engineered into the electrolyte microenvironment, and it could form adducts with N2, serving as a dynamic carrier for N2 transport. The electron-rich Lewis acidic sites and the dynamic carriers exerted a ‘pull–pull’ effect on N2, thereby weakening the NN bonds. Through electrochemical performance evaluation, the designed electrocatalytic scheme achieved an NH3 yield of ∼57.15 μg h−1 mg−1 and a Faradaic efficiency of ∼15.14 %. We anticipate that this methodology will provide new insights into the development of electrochemical ammonia synthesis, particularly in relation to multifaceted design.
