Against the backdrop of rising global concern for sustainable development, the advantages of renewable energy are undeniable. When examining renewable energy, such as solar and wind power, its potential as a perfect alternative to conventional (non-renewable) energy in diverse climates is notable, a potential measured against the yardstick of grid parity. In-depth studies have been undertaken to understand the underpinnings of the concept. In contrast, only a small fraction of studies have committed to a complete analysis of the research activity performed on it. A bibliometric and empirical review of worldwide grid parity, energy transition, and electricity cost research will be presented in this paper. read more To contextualize the advancements within this research domain, a comprehensive Scopus search was conducted to pinpoint and establish the trajectory of research development from 1965 to 2021. Scopus and VOSviewer's data facilitate an exploration of publications across several dimensions, such as publication volume, growth patterns, and subject comprehensiveness, and identify key research articles and journals, and major recent research interests. We examine governmental policies in developed and developing economies that have spurred the realization of grid parity in specific countries, within our discussion. An empirical study was conducted evaluating top-down, bottom-up, and artificial neural network techniques in the context of grid parity assessments. A consistent rise in research articles, scrutinizing grid parity, energy transition, and electricity cost, was reported by the study, commencing in the year 2006. Publications on this topic are geographically concentrated in the United States, Germany, China, the United Kingdom, and Spain, with these locations producing 422% of the overall publications. Finland, remarkably, stands out in Scopus, with the top 7 authors with the highest document counts, all coincidentally contributing to the nation's substantial progress in achieving grid parity. A minuscule 0.02% of the papers cataloged in Scopus come from African research institutions. Could a lack of willingness to share research findings about energy transitions be a factor impeding the widespread deployment of sustainable energy solutions in Africa? Therefore, intensive research efforts focusing on grid parity, the energy transition, and electricity cost reduction are now more essential than ever for developing nations. This article presents a review of current research trends regarding grid parity and energy transition, emphasizing the importance of Levelized Cost of Electricity (LCOE) models in evaluating renewable energy options.

The giant reed, a perennial grass (Arundo donax L.), demonstrates a fast growth rate, vegetatively multiplies, and has a rhizomatous structure. In adverse conditions, including drought, salinity, waterlogging, temperature fluctuations, and heavy metal contamination, this crop stands out for its biomass production on marginal and degraded lands. The giant reed's tolerance to these stressors is reviewed by analyzing its impact on its capacity for photosynthesis and biomass. The giant reed's resilience to various stresses, along with the accompanying biochemical, physiological, and morphological alterations impacting biomass production, were meticulously investigated and explained. Giant reed's potential in bioconstruction, phytoremediation, and bioremediation is also examined in this review. Arundo donax stands as a viable solution to both global warming issues and circular economy challenges.

Glioblastoma's status as a highly lethal cancer compels the urgent implementation of novel and efficient therapeutic interventions. One such example is nanobodies, promising nano-sized bio-drugs with noteworthy properties. Despite the targeting capability of nanobodies on intracellular proteins, an appropriate delivery system is essential to elevate their efficiency. This research investigated small extracellular vesicles' role as carriers for the anti-vimentin nanobody Nb79. Small extracellular vesicles containing Nb79 were generated through several methods, including incubation with glioblastoma cells, passive loading into isolated vesicles, or sonication of the isolated vesicles. The process of isolating small extracellular vesicles, secreted by glioblastoma cells, involved ultracentrifugation on a sucrose cushion. Nanoparticle tracking analysis determined the size distribution and average size of the small extracellular vesicles, both sonicated and non-sonicated. read more Cell incubation, passive loading, or sonication procedures for loading Nb79 into small extracellular vesicles were independently verified using Western blot and electron microscopy techniques. The WST-1 assay was used to evaluate the impact of small extracellular vesicles on cellular survival rates. The application of Nb79 to cells for the purpose of loading small extracellular vesicles was unsuccessful, causing substantial cell death. Conversely, sonication proves effective in producing Nb79-laden small extracellular vesicles, as evidenced by Western blot and electron microscopy analyses. The effect of small extracellular vesicles on cell viability was observed. U251 and NCH644 cell survival was augmented by 20-25% through the use of small extracellular vesicles lacking Nb79, conversely, the survival of NCH421k cells was decreased by 11% when these vesicles were loaded with Nb79. read more Nanobody loading into exosomes, facilitated by sonication, was demonstrated to reduce the overall survival of the cellular population. This method's applicability extends to other areas, including the targeted delivery of protein-based pharmaceuticals.

In light of the increasing interest in Life Cycle Thinking (LCT) for assessing the sustainability of processes, products, and services, it is imperative to conduct thorough, current syntheses and evidence-based critical outcome analysis to guide future research and policymakers. A systematic literature review is arguably the most suitable approach for highlighting the presence of effects, impacts, and methodological choices, charting the existing knowledge and gaps in LCT fields, including techniques such as Life Cycle Assessment, Life Cycle Costing, Social Life Cycle Assessment, and Life Cycle Sustainability Assessment. While a few statements and guidelines on health care and ecology, alongside a checklist for Life Cycle Assessment (STARR-LCA) systematic literature reviews, have been established, the field of LCT is still lacking a comprehensive framework for conducting similar reviews. To assist researchers in structuring the processes of gathering, synthesising, and reporting outcomes from search strategy development to critical evaluation, this paper proposes FLAVIA-LCT, a framework for systematic literature review, specifically for analyzing large volumes of information in life cycle thinking studies, incorporating all essential data in the review manuscript. A literature review concerning one or more LCT methods can be facilitated by this framework, making it accessible to all.

We investigate the use of single-channel and multi-channel metaphors in Facebook advertisements for food products from Jordan and the US. A collection of 180 advertisements, encompassing both monomodal and multimodal metaphors, was sourced from the Facebook pages of 12 prominent restaurants located in Jordan and the USA. The study reveals that both monomodal and multimodal metaphors in food advertising serve a persuasive function, not by clarifying the concrete nature of the product, but by crafting imaginative representations that enhance consumer attraction. The study of the corpus indicates the widespread use of contextual monomodal metaphors by advertisers to enhance advertisement memorability and inspire a more interactive interpretation by viewers. Food advertisements, employing culturally specific metaphors, can illustrate to viewers their essential role in the promotional process, as the results demonstrate.
