摘要： The aim of this paper is to show the concise chemico-physical adsorbent performance of water purification systems utilizing geo-(e.g.,allophane,clinoptilolite,and smectite)and bio-polymer materials(e.g.,chitosan or cellulose nanocomposite materials)and to propose an optimal ground-water remediation technique.The performance of geo-materials is evaluated based on the individual sorption and immobilization capacities for various priority substances and pollutants(e.g.,lead,zinc,cadmium,copper,arsenic,and others),their availability,and cost-efficient use.A systematic assessment of the sorption potential of geo-materials in comparison to other available sorbents used for the removal of harmful aqueous metal ions is made through a literature review.This paper introduces novel sustainable technologies based on natural and tailored silicate-polymerized substances(geo-materials and geopolymers),and highlights their applicability in the treatment of water and solid matter contaminated by heavy metal ions.The advantages of geo-materials and geopolymers over other commercially available sorbents used for heavy metal ion removal from solution are presented through a literature review.Benefits and current challenges of geo-materials and geopolymers applications in water processing technologies and in environmental remediation are discussed,with recognition of their performance,individual sorption and immobilization capacities,availability,and cost-efficient use.The applications described here comprise:(i)the removal of heavy metal ions from contaminated water using in-situ remediation strategies;(ii)heavy metal ion immobilization through co-precipitation with silicate binders in underground stabilization and waste solidification scenarios;and(iii)a proposal for a new geo-material/geopolymer-based solidification and stabilization technology for efficient,sustainable,and simultaneous treatment of soil/sediment and groundwater at environmental hotspots.Clay-substituted geopolymers,smectite,and zeolites are distinguished by their superb sorption and immobilization capacities for heavy metal ions,while biosorbents can play an important role in the removal of metals,metalloids(e.g.,arsenic),and other contaminants.More research on individual removal mechanisms of heavy metals will provide new clues on the development of remediation strategies in advanced scientific and field applications,and on atomic-to-micron scale processes occurring at the solideliquid interface.

摘要： Can Romania have a sustainable health system,so that the population can choose medical services at a state hospital or at a private hospital?A healthy state,with a healthy population,can ensure a viable balance with a secure future.Each country ensures its health system through levers,policies,and well-defined sources of funding,determined by demographics,geographical position,culture,nationality,has the necessary sources to implement its own health system,whether it is public or private.The programs that can be implemented in the health system start from the quality of medical services,which must be provided so that each patient can be sure that medical needs are achievable.We have a people with diverse traditions,a beautiful culture,specialized doctors and yet the medical system is still fragile.Funding programs must help us start this health system,build many private hospitals,so from prevention to services specialized,surgical,to be able to bring in the country specialized medical staff to us but gone to many states of the world.Any change can lead us to what we want,the health of our population in the village,the city,the majority of the population,the identification of possibilities to revive the health system.The market of private health systems,diversified by international players,bank brokers,manages to bring important changes in the health system.From a technical point of view,health insurance has its originality in the impossibility of being able to predict the insured’s illness and the costs necessary for recovery.Any risk related to personal injury,illness,temporary incapacity for work,can be identified,assessed in the form of medical expenses,loss of income,as a result,disability,borne by both the individual and the family,due to the inability to insure a normal activity,daily existence.Insurance can be considered as a method of controlling the health risk.The current situation regarding the disease of the population whit COVID often makes us understand that we must be prepared at all times.The situation of the pandemic SARS-COV 19 found a timely solution through the private health system.

摘要： The industrial manufacture of ammonia(NH_(3))using Fe-based catalyst works under rigorous conditions.For the goal of carbon-neutrality,it is highly desired to develop advanced catalyst for NH_(3)synthesis at mild conditions to reduce energy consumption and CO_(2)emissions.However,the main challenge of NH_(3)synthesis at mild conditions lies in the dissociation of steady N≡N triple bond.In this work,we report the design of subnanometer Ru clusters(0.8 nm)anchored on the hollow N-doped carbon spheres catalyst(Ru-SNCs),which effectively promotes the NH_(3)synthesis at mild conditions via an associative route.The NH_(3)synthesis rate over Ru-SNCs(0.49%(mass)Ru)reaches up to 11.7 mmol NH_(3)·(g cat)^(-1)·h^(-1) at 400°C and 3 MPa,which is superior to that of 8.3 mmol NH_(3)·(g cat)^(-1)·h^(-1) over Ru nanoparticle catalyst(1.20%(mass)Ru).Various characterizations show that the N_(2)H_(4)species are the main intermediates for NH_(3)synthesis on Ru-SNCs catalyst.It demonstrates that Ru-SNCs catalyst can follow an associative route for N_(2)activation,which circumvents the direct dissociation of N_(2)and results in highly efficient NH_(3)synthesis at mild conditions.

摘要： Despite the potential synergism, integrated watershed management and ecosystem services frameworks are rarely used jointly to address the myriad of current water-related issues. The two frameworks are used in this study to spatially identify ecosystem hotspots and coldspots for priority setting in natural resource management programs. Inferred proxies of carbon storage, groundwater supply, surface water supply, and soil retention ecosystem service production potentials were quantified for Texas, U.S., using two complimentary hydro-ecological models, and valued using a non-monetary multi-criteria valuation approach. Maps of individual and composite ecosystem service values showed that several services were co-located and unevenly distributed with most of the high-value hotspots clustered in the eastern part of the state. Individual impacts of land use, climatic and soil properties on the distribution and value of ecosystem services across space were discernable. The study underscored the need for holistic management of landscapes to take advantage of the multiplicity of benefits provided by nature. The approach can readily be incorporated into resource management programs to identify high-value ecosystem service production areas that need conservation, low-value areas that may need restoration, and anthropogenic activities influencing the distribution of ecosystem services.

摘要： The Non-Profit Sector(NPS)is composed of several non-profit institutions,whose social objectives and purposes are of general benefit to society and independent of the government and companies.Nonprofit foundations present themselves in modern society as philanthropic and altruistic agents.Foundations play an extremely important role in society because they act autonomously,in a long-term project and preserve their own economic resources,playing the role of substitutes for the state.There are foundations of a public and private nature.The current accounting standards approved for the NPS were developed and considered the different objectives and specificities of this type of entities.Through the accountability process,reliable information on the management of funds entrusted to foundations,as well as the results obtained during activities,is provided to all stakeholders.

摘要： The relationship between a university and its city is considered strategical to achieve university targeted ambitions and visions.The university-city relationship is also encouraged for the benefit of the city,as universities unleash their respective cities’potentials to act as driving forces not only for their local communities,but also for the whole nation.Therefore,maintaining a mutual relationship between the university and the city is considered essential to accomplish strategic goals for both.However,the nature of this relationship is quite complex,overlapped,interconnected,and diverse.Therefore,this paper conducted a systematic review of the literature on university-city and campus-city relationships to evaluate recent research trends to uncover the aspects that connect universities with their respective cities.The search included articles published in 4 different databases from January 1990 to January 2021.A total number of 50 articles were selected in this review.The findings uncovered different aspects that could help or hinder university-city relationship based on the physical and functional linkage between the campus and the city.Moreover,findings have shown that it is necessary to understand universities according to their contextual differences,as universities have shown different impacts on their respective cities in terms of their sizes and locations.Results have also shown that the impact of the physical connection between the university and the city goes far beyond campus’s accessibility as it deeply affects students’social life as well.Therefore,decision makers,stakeholders,and university administrators need to co-design campus development process especially in the early stages to maximize the mutual benefits of campus-city relationship.The main conclusions of this paper address several perspectives and lessons for a more sustainable campus-city relationship.

摘要： Traditional rural homegarden agroforestry system in the Chengdu Plain of China,called“Linpan”in Chinese,integrates the ecological functions of the landscape with human production activities.Studying the driving mechanisms of rural landscape changes in the Chengdu Plain is of great significance from stakeholders’perspective.Taking the Pidu Linpan Farming System(PLFS)in the suburban area of Chengdu(designated as one of China-Nationally Important Agricultural Heritage Systems in 2020)as a case,this study combined remote sensing image analysis,oral history interviews,and focus group interviews to elucidate the driving forces of landscape changes in the PLFS.The results show that tourism development,traffic accessibility,economic demand,and agricultural heritage protection measure are the main driving forces promoting the stability and maintenance of the traditional homegardens.In contrast,population ageing,land circulation,centralized residence,climate change,and living and recreational need are the forces leading to adverse changes in the traditional homegardens.In addition,these driving forces have led to the gradual abandonment of traditional agricultural activities and critical issues related to rural landscape planning and management.The current research indicates that infrastructure construction and increased traditional agricultural income are considered as the best practices of local stakeholders,promoting the development of the protected homegardens of heritage sites and tourist destinations.Finally,we put forward some suggestions to improve and maintain the traditional rural landscape:(1)establishing a benefit-sharing mechanism;(2)establishing a training system with traditional technology and culture;(3)strengthening infrastructure construction;(4)promoting the development of the agricultural industry;(5)improving the cultural quality of farmers;and(6)establishing a management system with legal effects.This research can provide a basis for the formulation of rural landscape planning and the orderly and healthy development of agricultural heritage in Chengdu Plain.
