Shaheed-e-Azam Bhagat Singh (1954): A Curious Case of the First Biopic on the Indian Revolutionary Martyr

Immediately after India’s independence, the Indian revolutionary martyr Bhagat Singh became the focus of several competing biopic projects. A censorship controversy erupted around the making of the now-lost film Shaheed-e-Azam Bhagat Singh (1954), the first biopic on the martyr. It became a contentious site where the interests of the filmmakers, former revolutionary colleagues of Bhagat Singh and his family members, and various other stakeholders like public representatives, intersected with an almost disinterested state. Following Debashree Mukherjee’s (2019) methodological approach of considering film censorship ‘as a productive material site for the study of lost films’, this article enters into a microhistory of this controversy by utilising bureaucratic paperwork and filmic and nonfilmic paratextual material to compensate for the absent film element. By tracing the very first attempts which were made to mount a biopic on Bhagat Singh, I try to investigate personal and political motivations behind the race to make the first biopic on the revolutionary martyr. For this purpose, I employ Chris Moffat’s (2019) mobilisation of the metaphors of corpse, corpus and corps, which he productively uses to understand the politics behind the multifarious afterlives of Bhagat Singh and wrangle over his revolutionary inheritance in the post-colonial period, and make a case for the importance of the study of Bhagat Singh’s hitherto neglected biopics by arguing that the time of their making, their production contexts and attendant controversies afford us unique insights into what Moffat terms the politics of ‘India’s revolutionary inheritance’.

Satellitengestützte Gewinnung pflanzlicher Rohstoffe für die Herstellung hochwertiger pharmazeutischer Produkte

AbstractFor the worldwide sourcing of medicinal plants as a high-quality raw material for pharmaceutical processing, the use of satellite data and drones is of great importance for quality assurance, risk assessment and risk mitigation, for finding new raw material occurrences, research and development and as part of GACP-compliant documentation and audits.In many cases, recording the exact location data using GPS provides the basis for subsequent evaluations and assessments of risks to the product and the environment. In audits, they provide exact and quickly available documentation of the production site or region for wild collection, the location of primary processing and the transportation routes of the sensitive fresh matter for subsequent drying.Screenings are also based on this method and allow geographical “mapping” in order to identify certain characteristics of populations or individual plants, e. g., as eco- or chemotypes. These can be propagated and cultivated as “elite crops” for specific requirements.Remote sensing satellite images visualize structures, colours and plant species in natural habitats and enable the identification of medicinal plant occurrences in unknown areas. Recognition requires training with data that must be obtained on site.

Construction of Intelligent Perception Network Based on Rocket Assembly Workshop

The rocket assembly is a crucial link in the rocket production process. With the increase of national space missions, how to quickly adapt to the high-density launch stage and improve the efficiency and quality assurance of the assembly workshop has become an urgent problem to be solved. Aiming at the problems of the low production efficiency caused by low information level of production site and the low intelligent degree of material management and distribution, an intelligent perception network based on the rocket assembly workshop is proposed in this paper. This intelligent perception network is equipped with functionalities such as intelligent perception, adaptive adjustment, data communication, remote monitoring, and management. It is designed to not only increase the intelligence level of assembly workshops but also effectively address the issue of low production efficiency.

Genetically defined nucleus incertus neurons differ in connectivity and function.

The nucleus incertus (NI), a conserved hindbrain structure implicated in the stress response, arousal, and memory, is a major site for production of the neuropeptide relaxin-3. On the basis of goosecoid homeobox 2 (gsc2) expression, we identified a neuronal cluster that lies adjacent to relaxin 3a (rln3a) neurons in the zebrafish analogue of the NI. To delineate the characteristics of the gsc2 and rln3a NI neurons, we used CRISPR/Cas9 targeted integration to drive gene expression specifically in each neuronal group, and found that they differ in their efferent and afferent connectivity, spontaneous activity, and functional properties. gsc2 and rln3a NI neurons have widely divergent projection patterns and innervate distinct subregions of the midbrain interpeduncular nucleus (IPN). Whereas gsc2 neurons are activated more robustly by electric shock, rln3a neurons exhibit spontaneous fluctuations in calcium signaling and regulate locomotor activity. Our findings define heterogeneous neurons in the NI and provide new tools to probe its diverse functions.

A novel noble-metal-free FeS2/Mn0.5Cd0.5S heterojunction for enhancing photocatalytic H2 production activity: Carrier separation, light absorption, active sites

BackgroundThe development of efficient and noble-metal-free photocatalysts is greatly essential for photocatalytic hydrogen production. However, the photocatalytic activity of a single photocatalyst is usually limited for various reasons. MethodsHerein, FeS2/Mn0.5Cd0.5S (FSMCS) heterojunctions were constructed by a simple solvent evaporation method. The morphological characterizations revealed a raspberry-like hollow microsphere structure for FeS2 and irregular granularity for Mn0.5Cd0.5S. Photoluminescence (PL) and electrochemical experiments indicated that the FSMCS composite effectively facilitated the separation of photogenerated electron-hole pairs. The UV–vis diffuse reflectance spectrum (DRS) showed that, in FSMCS composite, the visible light absorption range was effectively expanded to the full visible light. Significant findingsExcellent photocatalytic activity in FSMCS heterojunctions without loading noble metals because FeS2 could serve an active site for hydrogen production. The optimum FSMCS composite had excellent photocatalytic hydrogen production activity (6.1 mmol·g−1·h−1), which was 5.6 and 2.3 times higher than that of the pristine Mn0.5Cd0.5S (1.1 mmol·g−1·h−1) and Mn0.5Cd0.5S-1 %Pt (2.7 mmol·g−1·h−1). Meanwhile, in four round-robin tests, the activity of the 5FSMCS photocatalyst did not significantly decrease. This work proved that combining Mn0.5Cd0.5S and non-precious metal cocatalysts to construct heterojunctions is a promising strategy for photocatalytic hydrogen production.

The University As Infrastructure of Becoming: Re-Activating Academic Freedom Through Humility in Times of Radical Uncertainty

ABSTRACT Traditionally, the field of science and technology studies (STS) considered the scientific laboratory as the central site of knowledge production and technological development. While providing rich analyses of the social construction of scientific knowledge and the role of non-human actors, STS scholars have often neglected the university – the very context in which laboratories themselves are embedded – as a relevant object of research. In this paper, we argue for re-introducing the university as a relevant category and object of analysis by using the notion of epistemic virtues to link epistemic culture – traditionally the focus of STS – and epistemic structure – traditionally the focus of higher education studies. Advancing this line of argumentation, we make three analytical moves. First, we explore academic freedom as a specific version of negative liberty that extends beyond disciplinary boundaries. We suggest that academics continuously negotiate academic freedom considering culturally and socially situated epistemic virtues such as objectivity and neutrality. Second, we introduce the notion of humility to revisit scientific knowledge production more generally and academic freedom in particular. Finally, we argue that practicing humility leads to enacting the university as an infrastructure of becoming otherwise, thereby enriching our understanding of universities as distinct and highly complex social spaces with a logic of their own.

This will involve developing strategies to enhance storage capacity and mitigate the risk of CO2 leakage, contributing to the sustainable management of carbon emissions. In conclusion, future geological research will play a critical role in advancing renewable energy and carbon capture technologies, offering sustainable management techniques that are essential for addressing climate change. By focusing on innovative mapping, monitoring, and modeling approaches, researchers can pave the way for a more sustainable energy future.

Insights into the role of PGF2α in canine periparturient myometrium.

Parturition in dogs is subjected to complex hormonal regulation, with the involvement of prostaglandin F2α (PGF2α) still not fully understood. To investigate uterine inertia (UI), the most prevalent maternal reason for dystocia in the bitch, a better understanding of undisturbed uterine, especially myometrial function, is crucial. Our aim was to gain deeper insights into the role of PGF2α in the canine parturient myometrium. Uterine biopsies were obtained during medically indicated cesarean sections. To test for stimulatory effects of PGF2α in vitro, circular and longitudinal myometrial layer tissue strips were challenged with 50pM, 0.5µM, and 50µM PGF2α. Prostaglandin-endoperoxide synthase 2 (PTGS2) and PGF2α-receptor (PTGFR) mRNA expressions were compared between primary UI (PUI) and obstructive dystocia (OD) samples in isolated parturient myometrium. PTGFR protein expression was assessed in full thickness uterine samples. PGF2α concentrations were analyzed in canine interplacental tissue around term. In the organ bath, the contractile response to PGF2α was limited to the circular layer at the highest dosage. Correspondingly, PTGFR immunohistochemical staining was significantly stronger in the circular layer (p ≤ 0.01). PTGS2 gene expression did not differ between PUI and OD, whereas PTGFR gene expression could not be quantified. Local uterine PGF2α concentrations correlated negatively with serum P4 levels and were the highest during prepartum luteolysis while being significantly lower in PUI. Conclusively, despite the significant increase in local PGF2α concentrations at birth, confirming the interplacental tissue as a production site, our results suggest that PGF2α might affect uterine contractility during labor, mainly indirectly.

Persistence of PFOA Pollution at a PTFE Production Site and Occurrence of Replacement PFASs in English Freshwaters Revealed by Sentinel Species, the Eurasian Otter (Lutra lutra).

Concentrations of 33 PFASs were determined in 20 Eurasian otters, sampled 2015-2019, along a transect away from a factory, which used PFOA in PTFE manufacture. Despite cessation of usage in 2012, PFOA concentrations remained high near the factory (>298 μg/kg ww <20 km from factory) and declined with increasing distance (<57 μg/kg ww >150 km away). Long-chain legacy PFASs dominated the Σ33PFAS profile, particularly PFOS, PFOA, PFDA, and PFNA. Replacement compounds, PFECHS, F-53B, PFBSA, PFBS, PFHpA, and 8:2 FTS, were detected in ≥19 otters, this being the first report of PFBSA and PFECHS in the species. Concentrations of replacement PFASs were generally lower than legacy compounds (max: 70.3 μg/kg ww and 4,640 μg/kg ww, respectively). Our study underscores the utility of otters as sentinels for evaluating mitigation success and highlights the value of continued monitoring to provide insights into the longevity of spatial associations with historic sources. Lower concentrations of replacement, than legacy, PFASs likely reflect their lower bioaccumulation potential, and more recent introduction. Continued PFAS use will inevitably lead to increased environmental and human exposure if not controlled. Further research is needed on fate, toxicity, and bioaccumulation of replacement compounds.

Modeling dominant height growth of teak plantations in the Caribbean region of Colombia

Identifying sites with adequate biological productivity is a critical factor in ensuring timber production and the profitability of forest-based investments. The productivity of forest sites is influenced by climatic, edaphic and topographic variables, as well as by silvicultural practices. Site index is a phytocentric method widely used to assess site productivity and its estimation is based on dominant height growth modeling. Teak is the fifth most planted forest species in Colombia, and its importance is associated with high economic returns and profitability. This study aims to model dominant height growth using the generalized algebraic difference approach for teak plantations established in the Caribbean region of Colombia. The Lundqvist-Korf model, in which the correlation of the residuals was handled with a continuous autoregressive specification of the first order, resulted in a satisfactory statistical estimation of the dominant height growth. The results indicate that in the Caribbean region of Colombia, productive sites for the establishment of teak plantations can be found as productive as in some tropical American countries and better than some sites in Asian countries. This suggests a potential for the expansion of teak plantations and forest-based investments in Colombia.

Soilless Plug Nursery Seedling – A Boon for Farmers

Inadequate availability of quality seeds and planting materials is one of the major limiting factors affecting productivity, profitability and quality of vegetables in the India. Higher profits can be accrued by the farmers, if they have better access to high quality seed and planting materials of the improved varieties at reasonable costs close to their production sites.

Phytomonitoring of medicinal plants: pests and diseases in the VILAR botanical garden

Medicinal plants represent a separate group of plants that requires an environmentally safety approach to their protection from harmful organisms. The biotic factor significantly affects on the productivity of medicinal plants and the quality of medicinal raw materials obtained from them.The VILAR Botanical Garden is a unique scientific and crop production site, its main task is the conservation of rare species of medicinal plants, as well as the development agrotechnologies for species recently taken from nature, or another regions and countries. However, when we growing plants in biocollections on one place for a number of years, there is quite favorable conditions for the reproduction of pests and the spread of diseases. The monitoring results make it possible to monitor and predict the condition of crops on experimental plots and in biocollections. At the same time, a purposeful systematic study of plant pests and diseases in the VILAR Botanical Garden has not been carried out in recent years. Our studies was conducted in 2022–2023 years on 63 species of medicinal plants and allowed to clarify the species composition of pests, including 26 species of phytophages and 9 species of pathogenic fungi. The phytosanitary condition of the regions of the Botanical Garden and the crops on the experimental field was satisfactory, there was no loss of species or crops from the collection due to severe disease or pest damage. Representatives of the family of leaf beetles (Chrysomelidae) and true aphids (Aphididae) had the greatest prevalence among pests, among the diseases — powdery and rusty.

Assessment of hydrogen storage potential in depleted gas fields and power-to-hydrogen conversion efficiency: A northern California case study

This study assessed the potential for storing hydrogen underground in depleted gas fields using Northern California as a case study. We examined how much hydrogen California could produce from the electrolysis of curtailed solar and wind energy. Afterward, we assessed the geological and reservoir properties of fields that could potentially support safe and secure underground hydrogen storage. We applied two stages of a three-stage process to select prospective hydrogen storage sites in depleted gas fields. The first stage of the screening process involved integrating geoscience and environmental factors in order to identify the fields that will not be considered suitable for hydrogen storage. Among 182 depleted and underground gas storage fields in Northern California, 147 were disqualified in the first stage of the assessment. The remaining 35 fields were scored and ranked in stage two based on their potential to maximize hydrogen storage and withdrawal. High-scoring sites for underground hydrogen storage and production included reservoirs with dips between 5° and 15°, reservoir porosity above 20%, reservoir flow capacity above 5000 mDm, and reservoir depths between 430 m and 2400 m. We determined that a total of 203.5 million tonnes of hydrogen could be stored at the ten high-scoring sites. We estimated the potential hydrogen recovery from a hypothetical depleted field in California and evaluated the efficiency of converting the curtailed renewable electricity to hydrogen via electrolysis, storing it in the subsurface, and converting produced hydrogen back to electricity. Based on the results, we determined that depleted gas fields have sufficient underground storage capacity to store hydrogen produced from Northern California's curtailed renewable energy sources. Hydrogen recovery efficiency was estimated to be larger than 75% and was limited by the bottom hole pressure of the withdrawal well, hydrogen mixing with in-situ gas, and hydrogen spreading laterally. This study found that power-to-hydrogen-to-power round-trip efficiency maxed out at 36%. Improvements in hydrogen recovery could increase the round-trip efficiency by 8%, while improvements in electrolyzer efficiency could increase the round-trip efficiency by 33%.

Weathering increases the acute toxicity of plastic pellets leachates to sea-urchin larvae—a case study with environmental samples

Microplastics, particles under 5 mm, pervade aquatic environments, notably in Tarragona’s coastal region (NE Iberian Peninsula), hosting a major plastic production complex. To investigate weathering and yellowness impact on plastic pellets toxicity, sea-urchin embryo tests were conducted with pellets from three locations—near the source and at increasing distances. Strikingly, distant samples showed toxicity to invertebrate early stages, contrasting with innocuous results near the production site. Follow-up experiments highlighted the significance of weathering and yellowing in elevated pellet toxicity, with more weathered and colored pellets exhibiting toxicity. This research underscores the overlooked realm of plastic leachate impact on marine organisms while proposes that prolonged exposure of plastic pellets in the environment may lead to toxicity. Despite shedding light on potential chemical sorption as a toxicity source, further investigations are imperative to comprehend weathering, yellowing, and chemical accumulation in plastic particles.

FEATURES OF RECEIVING THE GASOLINE FRACTION BY THERMAL PYROLYSIS OF POLYOLEFIN RAW MATERIALS

The article examines the peculiarities of the process of thermal pyrolysis of secondary polymer raw materials, aimed at obtaining a gasoline fraction - the basis for obtaining mixed or synthetic automobile gasoline. Based on the global experience of polymer processing, polyolefins represented by high-density polyethylene (HDLP) and polypropylene (PP) were chosen for the study. Thermal pyrolysis was carried out at atmospheric pressure (0.10-0.12 MPa) on a reactor-type laboratory installation with subsequent removal of the gasoline fraction (30-210 °C) from liquid pyrolysis products according to the ASTM D 86 method. It has been established that the temperature interval in which pyrolysis of polyolefin raw materials must be carried out is for HDLP - 400-430 °С (the maximum output of the gasoline fraction at 420 °С); for PP - 350-370 °C (maximum yield of gasoline fraction at 365 °C). By controlling the duration of thermal pyrolysis, it is possible to increase the yield of the gasoline fraction by an average of 15-17%, which must be taken into account during the industrial implementation and further operation of pyrolysis plants for polymer raw materials. Increasing the temperature of the end of boiling of the gasoline fraction from 150 °С to 210 °С allows to increase its output by 9% (for HDLP) and by 12% (for PP). But at the same time, there is also an increase in the content of olefins in it (by 13-14%), which is a positive point from the point of view of resistance to detonation of the gasoline fraction, and a negative point - in view of its low chemical stability. The conducted studies showed that secondary polyolefin raw materials should be considered as an alternative to classic raw materials (oil and gas condensate), and the pyrolysis process as the main technological process for obtaining the gasoline fraction - the basis for obtaining commercial automobile gasoline. Prospective places for the implementation of this technology are both production sites of oil refineries and sites located in close proximity to places of accumulation of raw materials - ports, city landfills, special landfills.

Organophosphate esters in milk across thirteen countries from 2020 to 2023: Concentrations, sources, temporal trends and ToxPi priority to humans

Recent increases in organophosphate ester (OPE) application have led to their widespread presence, yet little is known about their temporal trends in food. This study collected milk samples from 13 countries across three continents during 2020–2023, finding detectable OPEs in all samples (range: 2.25–19.7; median: 7.06 ng/g ww). Although no statistical temporal differences were found for the total OPEs during the 4-year sampling campaign, it was interesting to observe significant variations in the decreasing trend for Cl-OPEs and concentration variations for aryl-OPEs and alkyl-OPEs (p < 0.05), indicating changing OPE use patterns. Packaged milk exhibited significant higher OPE levels than those found in directly collected raw unpackaged milk, and milk with longer shelf-life showed higher OPE levels, revealing packaging material as a contamination source. No significant geographical differences were observed in milk across countries (p > 0.05), but Shandong Province, a major OPE production site in China, showed relatively higher OPE concentrations. The Monte Carlo simulation of estimated daily intakes indicated no exposure risk from OPEs through milk consumption. The molecular docking method was used to assess human hormone binding affinity with OPEs, amongst which aryl-OPEs had the highest binding energies. The Toxicological-Priority-Index method which integrated chemical property, detection frequency, risk quotients, hazardous quotients and endocrine-disrupting effects was employed to prioritize OPEs. Aryl-OPEs showed the highest scores, deserving attention in the future.

Transnational companies in environmental conflicts: Rio Tinto, anti-mining resistance in Serbia, and the contradictions of Europeanization

AbstractAfter decades of outsourcing mining activities, Global North governments have begun to domesticate production sites. This strategy aligns with decarbonization goals but also contributes to the emergence of new environmental conflicts and protest movements. The analysis of these movements provides an important insight into the changing shape of transnational rule in the context of resource extraction for the European Green Deal. Building on the approach to reconstruct rule from resistance, we reconstruct the anti-mining resistance movement against a lithium mine in Serbia. Tracing their tactics and addressees, we identify three main conflict actors that the movement is opposed to (the transnational mining company Rio Tinto, the Serbian government, and the European Union (EU)). By addressing these institutions, the protesters do not only constitute a multifaceted conflict constellation around the Jadar project, but they also submit an argument about who can and who is allowed to dictate to others how they ought to behave. While all involved parties play their part, the EU appears more as a structural force during the conflict, preconfiguring the possible conduct of others. Particularly, the accession process places contradictory expectations on Serbia, both enabling and restricting the agency of the government and domestic protest movements. Yet, transnational companies are likely profiting from this constellation in the long run, because the inbuilt contradiction between a commitment to green policies and a pressure to open markets to foreign investments in the context of the accession process is conducive to that end.

A structured investigation on the site supervisory traits in applying science and technology related fundamental concepts in construction operations

Purpose Productivity increase is correlated with profitability, sustainability and competitiveness of the construction firms. Recent studies reveal that the primary causes of productivity decline are poor usage of scientific and technological advances, ineffective supervision strategies and poor apprenticeship facilities/opportunities. Accordingly, the purpose of this study was to evaluate how well construction supervisors can utilise fundamental science and technological concepts/ideas to increase the efficiency and productivity of construction activities. Design/methodology/approach A new strategic layout was designed with the use of potential training guide tools. Based on the designed layout, a new supervisory training programme was developed, and 62 construction supervisors were selected, trained and evaluated in line with six parts of competencies and the relevant learning domains. An assessment guide with different levels of descriptions and criteria was developed through literature analysis and expert interviews. The research tools were verified using comprehensive approaches. Findings The overall mean values of supervisors’ performance scores indicate proficient-level grades in the competency characteristics related to taking measurements, generating drawings/designs using manual techniques and computer-aided tools, involving Bill of Quantities (BOQ) preparations and preparing training plans/materials for improving the competencies of labourers on estimation, measurements and understanding drawings. Their proficiency was notably lower in the use of information and communication technology application tools in construction tasks compared to others. The findings point to a modern generalised guideline that establishes the ranges of supervisory attributes associated with science and technology-related applications. Research limitations/implications The study outcomes produce conceptualised projections to restructure and revalue the job functions of various working categories by adding new definitions within the specified scope. This may result in constructive benefits to upgrading the current functions associated with urbanisation, sustainability and society. The implementation of the study’s findings/conclusions will have a significant impact on present and future practices in other developing nations and developing industries, even if they are directly applicable to the Sri Lankan construction industry. Originality/value Up to certain limits/stages, the study fills not only the knowledge gap in the field of creating protocols and application techniques connected to lifelong learning and skill enhancement/upgrading but also the existing gaps in work attributes and roles of construction supervisors associated with the utilisation of fundamental science and technological concepts/ideas towards reinforcing sustainable and productive site operations.

Examination of the effects of excess microalgae availability on the disruption of mussel byssus secretion

The present study evaluated the effects of food availability on byssus secretion in the hard-shelled mussel Mytilus coruscus. Byssus production was evaluated, and foot tissue transcriptomes, the site of byssus production, were generated. The results showed that byssus secretion was disrupted in mussels fed high levels of microalgae (HFL, 88.8 mg/L day−1), compared to the control group (p < 0.05), and that more byssus production occurred in the HFL group during the recovery period. Byssus secretion was not affected in mussels fed low levels of microalgae (8.88 × 10−3 mg/L day−1), but the shedding of byssus filaments was significantly increased compared to the control mussels (p < 0.05). Transcriptome data of the foot tissue revealed that lysosome, FoxO signaling, and autophagy pathways involved in autophagic cell death and apoptosis were significantly affected (p < 0.05) and may explain differences in byssus growth under modified food availability in M. coruscus. High feed levels modified metabolic pathways, such as sphingolipid, tyrosine, and phenylalanine, and downregulated genes coding for mussel foot proteins, which may explain reduced byssus production. The study found that contrary to expectation increased food availability reduced mussel byssus production by altering foot metabolism and promoting autophagy of foot tissue.
