The concept of sustainable consumption patterns emphasizes the necessity for individuals and communities to shift towards consumption habits that minimize environmental impact, conserve resources, and support long-term ecological balance. In a green economy, consumer behavior plays a pivotal role in driving the demand for sustainable products and services, which in turn influences production systems and business strategies. This paper explores the intersection of consumer choices and sustainability, investigating how factors such as awareness, values, social influence, and policy interventions impact the adoption of eco-friendly behaviors. By highlighting the barriers to sustainable consumption—such as perceived costs, lack of availability, and knowledge gaps—the discussion delves into how consumers can be empowered through education, incentives, and corporate responsibility to foster a green economy. Ultimately, it advocates for a holistic approach, involving stakeholders across sectors to promote behaviors that support sustainability at both individual and societal levels.

In the rapid development of urbanization, the sustained and healthy development of transportation infrastructure has become a widely discussed topic. The inspection and maintenance of asphalt pavements not only concern road safety and efficiency but also directly impact the rational allocation of resources and environmental sustainability. To address the challenges of modern transportation infrastructure management, this study innovatively proposes a hybrid learning model that integrates deep convolutional neural networks (DCNNs) and support vector machines (SVMs). Specifically, the model initially employs a ShuffleNet architecture to autonomously extract abstract features from various defect categories. Subsequently, the Maximum Relevance Minimum Redundancy (MRMR) method is utilized to select the top 25% of features with the highest relevance and minimal redundancy. After that, SVMs equipped with diverse kernel functions are deployed to perform training and prediction based on the selected features. The experimental results reveal that the model attains a high classification accuracy of 94.62% on a self-constructed asphalt pavement image dataset. This technology not only significantly improves the accuracy and efficiency of pavement inspection but also effectively reduces traffic congestion and incremental carbon emissions caused by pavement distress, thereby alleviating environmental burdens. It is of great significance for enhancing pavement maintenance efficiency, conserving resource consumption, mitigating environmental pollution, and promoting sustainable socio-economic development.

Objective: Recently, the application in the field of germplasm resource conservation has become an important application of primordial germ cells (PGCs). However, due to the lack of deep understanding of the biological characteristics of PGCs at different time points, there is no systematic scheme for the selection of PGCs at which time points in practical application, which affects the practical application effect of PGCs. This study aims to clarify the differences in PGCs during development. Methods: Here, migration experiment, EdU proliferation assay and cell apoptosis assay were conducted to compare the differences in the migration ability, the proliferation ability and the recovery efficiency among female and male PGCs at E3.5, E4.5, and E5.5, which were explained by the following transcriptome sequencing analysis. Results: We found that there were larger differences between female and male PGCs at different embryonic ages, while smaller differences between female and male PGCs at the same embryonic age. Further comparison showed that the cell migration ability of female and male PGCs decreased gradually during development, so female and male PGCs at E3.5 are more suitable for in vitro allotransplantation. At the same time, the proliferation ability of PGCs gradually decreased during development, and cell adhesion and extracellular matrix communication were weakened, indicating that female and male PGCs of E3.5 are more suitable for in vitro long-term culture cell line establishment. Interestingly, female and male PGCs at E5.5 showed strong DNA damage repair ability, thus more suitable for in vitro long-term cryopreservation. Conclusion: This study provides a theoretical basis for systematically selecting PGCs at suitable developmental time points as cell materials for efficient utilization by analyzing the characteristics of female and male PGCs at different developmental time points based on transcriptome.

Sustainability means that the current use of resources does not compromise the well-being of future generations. Ever since Malthus (1798) hypothesized that population tends to grow faster than the growth of resources to support the population, people have claimed that current resource use is unsustainable, so future generations will be materially worse off than those in the present, yet for more than two centuries this has not been the case. The reason is that markets, and market prices, act to conserve scarce resources, and in market economies, entrepreneurs have an incentive to discover more efficient ways to use resources. The claim that twenty-first-century capitalist economies are not sustainable is not supported by the evidence. [ABSTRACT FROM AUTHOR]

Foreign language peace of mind (FLPOM) is conceptualized as a Chinese culture-specific low-arousal positive emotional state of inner peace and harmony. It is used to describe learners' psychological well-being in the Chinese English as a foreign language (EFL) context. This study examines the intermediate mechanism for the positive effect of FLPOM on language achievement by testing learners' cognitive engagement as a mediator on the relationship between FLPOM and language achievement and competitive psychological climate as a moderator of the mediation effect. Foreign language enjoyment (FLE), a comparatively high-arousal positive emotion, is also tested in the same model for comparison purposes. Results showed that cognitive engagement mediated the relationship between both FLPOM and FLE and language achievement and that competitive psychological climate negatively moderated (i.e., weakened) the mediation effect of cognitive engagement on FLE and achievement, but did not moderate the mediation effect of cognitive engagement on FLPOM and achievement. The findings point to the role of FLPOM in gaining learners' individual resources (e.g., cognitive engagement) and, more importantly, the distinctive role of the low-arousal emotion of FLPOM in lowering resource loss and maintaining learner engagement in high resource loss (e.g., high competitiveness, high stress) circumstances.

The study examines the spatiotemporal dynamics of landscape anthropization in the Kiziba-Baluba Hunting Domain (KBHD), near Lubumbashi in southeastern Democratic Republic of Congo, facing increasing human threats. It assesses these dynamics from 1989 to 2023 using remote sensing, Geographic Information Systems (GIS), and landscape ecology principles. The results reveal a significant decrease in forest cover, declining from 70.33 % in 1989 to 26.22 % in 2023, with an annual deforestation rate of -1.84 %. This deforestation has led to the expansion of savannas (63.93 %), agriculture (5.76 %), and built-up and bare soil (0.93 %) through patch creation and aggregation. The level of landscape disturbance has increased sixfold over 34 years, from 0.42 in 1989 to 2.81 in 2023. The reduction in the size of the largest forest patch and increased spatial isolation show rising fragmentation and dissection, often followed by the attrition of residual patches. These findings highlight the inefficiency of current conservation measures in KBHD, indicating a need for restructuring management, redefining protected area boundaries, developing a suitable management plan, implementing reforestation programs, strengthening enforcement of environmental laws, and actively involving local communities.

Abstract Vietnam’s economy is rapidly growing, marked by an increasing reliance on fossil fuels and renewable energy sources, resulting in unsustainable consumption patterns. The primary objective is to investigate the implications of renewable and non-renewable resource consumption on the overall resource availability over the long term, as indicated by the ecological footprint. Furthermore, the study incorporates economic growth to examine the Environmental Kuznets Curve hypothesis in Vietnam. Methodologically, the study adopts the asymmetric Autoregressive Distributed Lag model, utilizing time-series data ranging from 1986 to 2022. The findings highlight that Vietnam’s economic growth still use more natural resources while compromising the overall ecological reserve. Furthermore, the research findings suggest that the Environmental Kuznets Curve hypothesis does not hold in the context of Vietnam. Specifically, the increasing share of primary energy sourced from fossil fuels is observed to coincide with an increase in demand in ecological footprint. In contrast, an increase in primary energy consumption from renewable sources demonstrates a marked reduction in natural resource demand over the long term. Several strategies are recommended to enhance the resilience of environmental resources, such as adopting new and energy-efficient technologies is necessary within the industrial sector, promote the utilization of renewable energy sources, enhance waste management systems, transition from conventional energy to renewable sources in both production and consumption and the formulation of legislation on renewable energy usage.

In pursuit of sustainable solutions for water pollution mitigation, we have successfully employed electrospinning technology to fabricate a multilayered sodium alginate (SA)/polyethyleneimine (PEI)/polyvinyl alcohol (PVA) nanocomposite fiber membrane, with a focus on enhancing its adsorption capacity for Cu2+ ions in wastewater. Our research underscores the potential of this novel membrane, characterized by its small diameter, high uniformity, and expansive surface area, in effectively filtering heavy metal ions. By optimizing critical electrospinning parameters such as a voltage of 19.5 KV, a collector distance of 8 cm, a specific mass ratio of SA:PEI: PVA (1:2:6), and an injection rate of 8 μL/min, we achieved a nanofiber membrane with an average diameter of 112.5 nm, exhibiting exceptional morphological characteristics and high efficiency. Notably, the membrane exhibited an adsorption capacity of over 85% for Cu2+ during initial testing, maintaining over 80% efficiency throughout four consecutive filtration cycles. This work not only advances the field of nanocomposite membranes for water purification but also contributes significantly to the broader goal of achieving environmental sustainability by mitigating the impact of heavy metal contamination in water bodies.

Monitoring and measuring pharmaceutical pollutants in environmental samples is a vital and complex task due to their potential detrimental effects on human health, even at low levels. Using capillary zone electrophoresis (CZE) and ultra-high-performance liquid chromatography (UHPLC), it was possible to separate and measure three commonly used antipsychotic drugs, chlorpromazine (CPZ), haloperidol (HAL), and risperidone (RIS), in wastewater of the pharmaceutical industry. The technique of solid-phase extraction (SPE) was developed and implemented as a very effective method for preparing samples prior to analysis. The settings of the capillary electrophoretic and chromatographic techniques were adjusted to obtain the most efficient separation profile for the medications being studied. The concentration of all the medicines being investigated ranged from 0.5 to 50 µg/mL. SPE was used to treat real wastewater samples after a thorough validation process that followed the rules set by ICH-Q2B. The developed assays were then effectively employed to identify the tested antipsychotic substances in the real wastewater samples. The provided methodologies may be efficiently utilized to monitor the extent of environmental contamination caused by the investigated pharmaceuticals. [ABSTRACT FROM AUTHOR]

New approaches to thermal energy generation are necessary for reasons of resource conservation and environmental protection. One option is to convert coal-fueled boilers to mixtures based on coal and biomass or to mixtures with more efficient nontraditional fuels. However, that entails expansion of experimental resources and research. In the present work, the main stages in the combustion of carbonizates, biomass, and their mixtures are analyzed and the main stages in the combustion of such mixtures with nonisothermal heating are determined, taking account of synergy between the components. Carbonizate obtained by gasification of Chernogorsky coal, birch shavings, and their mixtures are subjected to thermal analysis in an oxidative medium, with heating at 20°C/min. The basic combustion characteristics are established: the ignition temperature of the volatiles and coke residue; the temperature at which combustion ends; the maximum rate of mass loss and the corresponding temperature; and the combustion index, which permits comparison of the combustibility of different fuels. The ignition temperature is 45% higher for the carbonizates than for birch shavings; the combustion index is lower by a factor of 25. The total combustion time is greater for the mixture than for individual fuels. The most energy-efficient fuel mixture is identified. Adding biomass to carbonizates may improve not only the combustion characteristics of the carbonizates but the environmental characteristics, thanks to the low ash content and the minimal sulfur and nitrogen content in the biomass waste.

The textile industry, renowned for its comfort-providing role, is undergoing a significant transformation to address its environmental impact. The escalating environmental impact of the textile industry, characterised by substantial contributions to global carbon emissions, wastewater, and the burgeoning issue of textile waste, demands urgent attention. This study aims at identifying the feasibility of the future use of textile scraps in the construction and architecture industry by analysing the effect of different binders. In this study, synthetic knitted post-consumer-waste fabrics were taken from a waste market for use as a reinforcement, and different binders were used as the matrix. In the experiment phase, the waste fabrics were mixed with synthetic binders and hydraulic binders to form brick samples. The mechanical and thermal properties of these samples were tested and compared with those of clay bricks. In terms of mechanical properties, unsaturated polyester resin (UPR) samples showed the highest mechanical strength, while acrylic glue (GL) samples had the lowest mechanical strength. White cement (WC) samples showed moderate mechanical properties. Through several tests, it was observed that UPR samples showed the highest values of tensile, bending, and compressive strengths, i.e., 0.111 MPa, 0.134 MPa, and 3.114 MPa, respectively. For WC, the tensile, bending, and compressive strengths were 0.064 MPa, 0.106 MPa, and 2.670 MPa, respectively. For GL, the least favourable mechanical behaviour was observed, i.e., 0.0162 MPa, 0.0492 MPa, and 1.542 MPa, respectively. In terms of thermal conductivity, WC samples showed exceptional resistance to heat transfer. They showed a minimum temperature rise of 54.3 °C after 15 min, as compared to 57.3 °C for GL-based samples and 58.1 °C for UPR. When it comes to polymeric binders, UPR showed better thermal insulation properties, whereas GL allowed for faster heat transfer for up to 10 min of heating. This study explores a circular textile system by assessing the potential of using textile waste as a building material, contributing to greener interior design. This study demonstrated the usefulness of adding short, recycled PET fibres as a reinforcement in UPR composites. The use of the PET fibre avoids the need to use a surface treatment to improve interfacial adhesion to the UPR matrix because of the chemical affinity between the two polyesters, i.e., the PET fibre and the unsaturated polyester resin. This can find application in the construction field, such as in the reinforcement of wooden structural elements, infill walls, and partition walls, or in furniture or for decorative purposes.

Multidimensional trait frameworks are increasingly used to understand plant strategies for growth and survival. However, it is unclear if frameworks developed at a global level can be applied in local communities and how well these frameworks—based largely on plant morphological traits—align with plant physiology and response to stress.We tested the ability of an integrated framework of plant form and function to characterise seedling trait variation and drought response among 22 grasses and forbs common in a semi‐arid grassland. We measured above‐ground and below‐ground traits, and survival to explore how drought response is linked to three trait dimensions (resource conservation, microbial collaboration, and plant size) associated with the framework as well as non‐morphological dimensions (e.g. physiological traits) that are under‐represented in global trait frameworks.We found support for three globally‐recognised axes representing trade‐offs in strategies associated with tissue investment (leaf nitrogen, leaf mass per area, root tissue density), below‐ground resource uptake (root diameter, specific root length), and size (shoot mass). However, in contrast to global patterns, above‐ground and below‐ground resource conservation gradients were oppositely aligned: root tissue density was positively correlated with leaf N rather than leaf mass per area. This likely reflects different investment strategies of annual and perennial herbaceous species, as fast‐growing annual species invested in lower density roots and less nitrogen‐rich leaves to maximise plant‐level carbon assimilation. Species with longer drought survival minimised water loss through small above‐ground size and low leaf‐level transpiration rates, and drought survival was best predicted by a principal component axis representing plant size.Contrary to our expectations, drought survival in seedlings did not align with the conservation or collaboration axes suggesting that seedlings with different functional strategies can achieve similar drought survival, as long as they minimise water loss. Our results also show that within local communities, expected trait relationships could be decoupled as some plant groups achieve similar performance through different trait combinations. The effectiveness of species mean trait values in predicting drought response highlights the value of trait‐based methods as a versatile tool for understanding ecological processes locally across various ecosystems.

Steel slag is an industrial by-product of steel production which is obtained during the pyrometallurgical process. Technological dissemination on effective utilization of steel slag in vast quantities globally is essential as the generation of steel is escalating year by year and the availability of steel slag is also in millions of tons. Though steel slag has been used for various applications, large quantities of steel slag have been utilized in the field of construction only. This review focuses on the recent advances on utilization of steel slag in construction sector and the impact of steel slag incorporation has been described in detail. Utilization of steel slag in construction industry as aggregate and cementitious material for the applications toward bricks production, asphalt mixes, radiation shielding concrete, foam concrete, self-compacting concrete, ceramic manufacturing, waterproof mortars and geopolymer composites fabrication has been discussed in detail. Steel slag will be an alternate source to conserve natural resources by utilizing large quantity of steel slag in construction industry. [ABSTRACT FROM AUTHOR]

Modern energy systems are complex multi-component systems that use mechanical, thermal, and electrical energy. As fossil fuel reserves decline, interest in renewable energy sources is growing everywhere, which is driving research into biogas production technologies. The purpose of this study was to evaluate technological approaches to reduce resource costs to produce renewable energy sources from organic waste (manure) from pig farms. This study employed the bibliographic method of research, laboratory method, biochemical methods (determination of the chemical composition of manure and wastewater), statistical, mathematical (calculation of economic efficiency), multicriteria analysis, and analytical method. Based on the conducted research, a resource-saving technology for the preparation of wastewater for use in the production of renewable energy in industrial pork production was developed, which ensures a reduction in capital and operating costs for biogas generation. It was found that the settling of the initial wastewater with a moisture content of 96.94±0.18% produces a sediment with a moisture content of 91.23±0.25% and a liquid fraction with a moisture content of 98.86±0.42%. At the same time, the organic matter in the sediment extracted from the original wastewater is about 87%, and in the liquid fraction – about 98% of the dry matter. The technological process includes centrifugal and gravity separation of the initial wastewater into fractions (sediment and liquid fraction), gravitational thickening of the sediment and its dosing for methane digestion to produce biogas. It was shown that the application of the proposed approaches can reduce capital investments by about 30%. Based on the multicriteria analysis, it was found that the proposed biogas production technology has a significant advantage in terms of the complex efficiency indicator of each of the considered options N(Ck) compared to the idealised one. For this technology, the objective function is the smallest according to the criteria considered and amounts to 0.1672, while the objective function of the baseline technology is 1.9 times worse. The findings of the study on the use of livestock by-products for resource-saving biogas production are planned to be used at pork production complexes and farms

It is shown that advanced achievements in the field of foundry technologies, purification of dust and gas emissions, recycling of secondary energy resources (SER), recycling of metals, regeneration of materials, processing and use of man‑made waste, allow us to talk about a modern foundry as a model of energy‑efficient, environmentally neutral production of the future.

The relevance of the problem under study is determined by the need to create a sustainable, efficient and environmentally safe energy complex. The growth of the world population, industrial development, and overall energy demand endanger the provision of society’s energy needs, making the need for research urgent at the present time. The purpose of the study is to examine optimal energy optimisation strategies, including alternative energy, compensation of reactive power, and energy efficiency management, to ensure the stable and efficient functioning of the energy complex. Among the methods used, analytical, classification, functional, statistical, and synthesis methods were applied. In investigating the optimisation of energy solutions, a thorough analysis of various aspects of alternative energy, reactive power compensation, and energy efficiency management was conducted. This analysis encompassed various aspects and parameters related to these areas, including technical, economic, and environmental indicators. As a result of the study, it was established that alternative energy has significant potential for ensuring sustainable development of the energy system. It can serve as a reliable source of energy that does not harm the environment and is not dependent on limited resources. In addition, reactive power compensation was recognised as an effective way to avoid energy losses in the system. This strategy helps to ensure more efficient energy use and reduce losses during transmission and distribution. Energy efficiency management also proved to be a key aspect in achieving energy supply sustainability. This allows optimising resource utilisation, reducing energy costs, and mitigating the negative impact on the environment. The practical value of the study lies in the development of innovative recommendations and strategies for energy optimisation, which will contribute to the creation of a stable, efficient, and environmentally safe energy complex and enhance its compliance with current and future challenges, making a considerable contribution to the development of science and the energy sector

It is substantiated that the cascade-circular model of innovative transformation of regional economic complexes should be based on a combination of the cascade principle of attracting material resources in the reproduction process and the principle of maximizing closed cycles in product chains. It is determined that the cascade principle is a sequential transition from one phase of production to another, based on the priority of formation of value chains and features of extracting the resource value of primary and secondary raw materials; the principle of maximizing closed cycles in product chains is a principle that provides for the minimization of unit costs and losses of the material substance of raw materials on the basis of the integrated use of primary raw materials through the use of waste-free and low-waste technologies and the most complete utilization of secondary raw materials in order to maximize the value added in food chains. It is identified that the key point in the formation of the cascade-circular model of innovative transformation of regional economic complexes is the formation of the structure-establishing innovation core (a complex of types of production and economic activity with appropriate supporting subsystems), which will be differentiated in the context of economic regions of Ukraine, based on: the existing production and technical base of material production; the level of infrastructural arrangement; available and projected reserves of natural raw materials; scientific and scientific-technical potential; opportunities for establishing inter-regional cooperative relations; participation of the region in the national division of labor and in ensuring national security. It is substantiated that the cascade-circular model of innovative transformation of the economy of the regions of Ukraine should be aimed at more effective use of secondary material resources in the reproduction process and at increasing the assimilation potential as a basic prerequisite for the transition to the rails of low-carbon development.

Bath galvanized substructures for rear‐ventilated façades – part 1 Thin‐walled steel components (0.8–2.5 mm) for substructures according to DIN 18516‐1 can be produced using galvanisation. Brackets and support profiles remain warp‐free, the thickness of the zinc layer is above the standard acc. to DIN EN ISO 1461. Flanging on the edges of the holes in the brackets and lateral edging increase the load‐bearing capacity, as do increasing sheet thicknesses. Load‐bearing profiles are also strengthened by lateral edging; U‐ and hat‐profiles are on top. Experimental tests in the climatic chamber revealed a gradation of the perforated brackets; the most favourable design is the bracket with three slotted holes. Thermal and mechanical tests have proven that galvanized components represent a static, thermal and economical alternative to commercially available substructure systems. [ABSTRACT FROM AUTHOR]

The construction of reinforced concrete (RC) structures inevitably consumes an excessive number of rebars, leading to significant cutting waste and carbon emissions. Extensive research has been conducted to minimize this issue and its consequences; however, these methods consistently consume a substantial number of rebars. This includes a previous study that utilizes the lap splice position optimization and special-length rebar concept without considering the lapping zone regulation. Moreover, conventional lap splices pose inherent drawbacks that could jeopardize the structural integrity of RC members. In contrast, mechanical couplers eliminate the need for rebar lapping, effectively reducing rebar consumption. This research aims to evaluate the impact of an integrated mechanical coupler and special-length-priority minimization algorithm on the reduction in rebar consumption and cutting waste in RC columns, achieving near-zero cutting waste. To validate the effectiveness of the proposed algorithm, it was applied to the column rebars of an RC building. The results revealed a significant reduction in the ordered rebar consumption by 18.25%, accompanied by substantial reductions in the cutting waste (8.93%), carbon emissions (12.99%), and total costs (9.94%) compared with a previous study. The outcomes provide the industry with insights into further reducing rebar consumption and its related consequences. Applying the proposed algorithm to various construction projects will further amplify the corresponding benefits. [ABSTRACT FROM AUTHOR]

This research explores the challenges and limitations faced at the basic level for the recycling of paper in an academic institute. It focuses on encouraging recycled paper use rather than bringing traditional virgin paper to prevent the rate of deforestation for reducing global warming. Data was collected from the academic institute via questionnaire and on-site observation and found that the institute was producing approximately 16 tons of wastepaper in a year. Besides that, another purpose of this research is to estimate the energy and assess the environmental effect by using the life cycle assessment as a tool. The results of this study revealed that traditional virgin paper derived from wood proves to be costly and less environmentally friendly than recycled paper. It also revealed that Traditional virgin paper has greater global warming, human toxicity, smog, acidification, and eutrophication potential than recycled paper. This study concludes that recycled paper does not only prove economically beneficent for any institution, but also beneficial for environment as well. [ABSTRACT FROM AUTHOR]

UHPFRC Precast Segments for Sustainable and Resource‐Efficient Concrete Bridge Construction Many of the concrete bridges currently in use in Germany are in a deficient condition due to their age or design. However, increased traffic loads also highly contribute to the fact that many of the existing bridges will have to be replaced in the medium term. Due to the many advantages of concrete structures, it can be assumed that concrete bridges will continue to be designed and built in the future. In the light of the increasing consequences of climate change and the pressing need to reduce CO2 emissions also in the building industry as well, there is an urgent need for research into climate‐ and resource‐friendly as well as sustainable but also economical concrete construction methods. A promising approach to fast, effective and resource‐optimized as well as CO2‐efficient construction is the use of high‐performance materials such as UHPFRC in combination with precast segmental construction. In this paper, starting from a monolithic box girder bridge made of normal strength concrete, numerical calculations are used to investigate how much material can be saved in segmented box girder bridges by varying the concrete compressive strength (normal and high‐strength concrete as well as UHPFRC). The life cycle assessment subsequently carried out on this basis for life cycle phases A1 to A3 showed that, when the material is fully utilized, the use of UHPFRC leads to very resource‐efficient and sustainable structures compared with normal‐ and high‐strength concretes.

This research work proposed an economic and eco-efficient idea to supplement the ductility and durability of concrete by the simultaneous incorporation of several processed waste materials i.e., ground blast furnace slag (GBFS), recycled coarse aggregate (RCA), and coconut fibre (CF). Two concrete families were produced containing 0% and 100% coarse RCA. GBFS was incorporated as by 25% replacement for cement. CF was used as a fibre reinforcement at 0.25% volume fraction. The results revealed that the recycled-aggregate concrete (RAC) modified with GBFS, CF, and modified plasticizer dosage can attain similar or higher mechanical performance than unmodified natural-aggregate concrete (NAC). At a later age, the strength gain in RAC mixes due to 25% GBFS addition was found to be notably greater than that observed in NAC mixes. At 91 days, RAC containing 0.25% CF and 25% GBFS correspondingly showed 30.5% and 33% more flexural strength and splitting tensile strength, as compared to conventional plain NAC. GBFS inclusion can effectively eliminate the corrosion risk of medium-strength NAC and RAC and control the negative effects of CF incorporation on the durability of concrete. RAC with 0.25% CF and 25% GBFS yielded 1.5% and 16% lower water absorption than plain NAC, at 28 and 91 days, respectively. The modification of SP dosage can substantially enhance the strength and permeability-resistance of CF-reinforced RAC.

The provided methodologies may be efficiently utilized to monitor the extent of environmental contamination caused by the investigated pharmaceuticals.

The Qinghai–Tibet Plateau, known as the "Third Pole of the World," has a rich variety of medicinal plants that play an important role in the field of medicine due to its unique geographical environment. However, due to the limited resources of Tibetan medicinal plants and the fragility of the ecological environment of the Qinghai–Tibet Plateau, more and more Tibetan medicinal plants are on the verge of extinction. As a reservoir of biologically active metabolites, endophytes of medicinal plants produce a large number of compounds with potential applications in modern medicine (including antibacterial, immunosuppressive, antiviral, and anticancer) and are expected to be substitutes for Tibetan medicinal plants. This paper reviews 12 Tibetan medicinal plants from the Qinghai–Tibet Plateau, highlighting the diversity of their endophytes, the diversity of their metabolites and their applications. The results show that the endophytes of Tibetan medicinal plants are remarkably diverse, and the efficacy of their metabolites involves various aspects, such as antioxidant, anti-disease and anti-parasitic. In addition, conservation measures for the resources of Tibetan medicinal plants are summarised to provide a reference for an in-depth understanding of the endophytes of Tibetan medicinal plants and to stimulate the scientific community to bioprospect for the endophytes of Tibetan medicinal plants, as well as to provide ideas for their rational exploitation.
