Landfill should be designed and constructed in line with the principle of environmental sustainability, guaranteeing over a period of less than one generation (typically considered 30 years) the environmental equilibrium of Final Storage Quality, when waste stability and immobilisation of contaminants is achieved and all active measures of control may be removed without posing any further risk to the environment. The practical definition of FSQ, when a landfill can be released from aftercare, and a procedure for the technical and administrative termination of the post-closure management phase are an evident regulatory strategic need to assure the design of sustainable landfill. The aim of this paper is to provide a criterion to define the FSQ of landfill, based on the control of the analytical emission parameters and of stability indexes related to the residual emission potential. These should concur with the law’s acceptance criteria for the landfilling of wastes (LAC), and with the legal limit values (LLV) established for the emission of contaminants into the environment. The interrelationship between, stability indexes (emission potential), analytical emission parameters, LAC and LLV is discussed and reference values are provided. Finally, the paper proposes a procedure for the termination of technical and administrative aspects following the post-closure management in accordance with FSQ.

Conceptual Relationship

This scoping review examines the conceptual relationship between the terms “environmental sustainability” and “quality of care” as used in academic studies on health care. We performed searches in Scopus and PubMed looking for potential semantic and practical associations between sustainability and quality of care, including potential conflicts. For the first part about associations, 11 search strings were used resulting in 1,488 studies of which 8 were eventually selected for analysis. For the latter part about conflicts, 4 search strings were used resulting in 45 studies of which 6 remained for analysis. Information about the following aspects was extracted from the studies that were included: interpretation and definition of sustainability, dimensions of quality of care, and tensions between quality and sustainability. Merely a few studies address a relationship betweenenvironmental sustainability and quality of care. Only “patient-centredness” and “safety” are associated with sustainability in academic literature. “Effectiveness” is rather interpreted as opposing it. “Efficiency” seems to be both associated and opposed to sustainability. The conceptual relationship between environmental sustainability and quality of care has not been thouroughly examined in academic studies which implies a blind spot in our knowledge. Only one study reports on conceptual and practical work for incorporating sustainability as a dimension of health care quality.

The City

Since the 1980s, a wide range of physical and non-physical interventions, including megaprojects and flagships to small-scale projects and temporary usage, are prescribed as catalysts for urban regeneration. The strategy of utilizing urban catalysts as a tool for urban renewal has been encouraging by many city authorities through specific subsidization and privileges. However, there is no correct and precise definition of the tools and the qualities they should provide as their impacts. Besides, some criticize the catalytic projects due to their unsustainable, unjust, and destructive consequences.  This paper intends to provide a more comprehensive definition of urban catalysts by reviewing the existing literature. The research has been done through a deductive and inductive approach to reach the principal dimensions and criteria for catalytic projects. It uses a series of potential projects and interventions in the City of Tehran (16 projects and practices) as case studies to check the dimensions and criteria and the quality of each project as catalysts. The quality of the selected case studies was ranked through expert judgment and checklist method. The findings show the cases' rank on how their catalytic impacts comply with sustainable development goals. According to the results, seven criteria (environmental sustainability, context-based development, pattern making, branding, social quality of life, economic prosperity, and market adaptability) are essential to ensure the sustainability of catalytic impacts of catalyst projects.

Definition Of

The paper considers the possibility of determining the coefficient of blackness or the degree of radiation for inhomogeneous surfaces during thermography. Such approach will allow increasing the accuracy of the analysis of the level of qualitative heat losses during the energy audit of the facility. As a rule, when conducting an energy audit, reference values are used which are given only for one type of material, which introduces an additional error both in the measurement and in the processing of the material.In the majority of cases, thermography is carried out on inhomogeneous surfaces that have different physical characteristics and correspondingly different values of the blackness coefficient. The proposed dependence makes it possible to take into account the heterogeneity of the surface according to the type of material and their ratio to the overall surface of the object under study.The use of this approach will increase the accuracy of the study in thermography and, accordingly, the quality of processing of the thermograms obtained.

ABSTRACTThe influence of boundary layer on the coefficient of adhesion between fibers and matrix in polymer composites was investigated. A multilayer model was introduced consisting of the two main-phases of the composite,that is the elastic inclusion and the viscoelastic matrix and a third intermediate phase consisting of a series of cylindrical layers of mechanical and physical properties varying between the limit values of the matrix and inclusion. The extent of the interlayer between main phases may be determined from the overall properties of the composite and the matrix. The model proved to be very flexible and describes conveniently the behaviour of the material. Moreover, the model allowed the definition of an adhesion coefficient, convenient to describe the quality of adhesion of the component materials and the introduction of an improved expression for the law of mixtures in polymeric composites.

Definition Of

During the past investigations of immunoferritin localization of intracellular antigens in ultrathin frozen sections, we found that the degree of negative staining required to delineate u1trastructural details was often too dense for the recognition of ferritin particles. The quality of positive staining of ultrathin frozen sections, on the other hand, has generally been far inferior to that attainable in conventional plastic embedded sections, particularly in the definition of membranes. As we discussed before, a main cause of this difficulty seemed to be the vulnerability of frozen sections to the damaging effects of air-water surface tension at the time of drying of the sections.Indeed, we found that the quality of positive staining is greatly improved when positively stained frozen sections are protected against the effects of surface tension by embedding them in thin layers of mechanically stable materials at the time of drying (unpublished).

Comprehensive Study

The article describes the results of comprehensive study aiming at increase of quality of LED luminaires and definition of the nature of changes in their correlated colour temperature (CCT) in the course of operation. Dependences of CCT of LED luminaires with remote and close location of phosphor for 10 thousand hours of operation in different electric modes were obtained; the results of comparison between the initial and final radiation spectra of the luminaires are presented; using mathematical statistics methods, variation of luminaire CCT over the service period claimed by the manufacturer is forecast; the least favourable electric operation modes with the highest CCT variation observed are defined. The obtained results have confirmed availability of the problem of variation of CCT of LED luminaires during their operation. Possible way of its resolution is application of more qualitative and therefore expensive LEDs with close proximity of phosphor or LEDs with remote phosphor. The article may be interesting both for manufacturers and consumers of LED light sources and lighting devices using them.

The definition of the multimorbidity concept reveals insufficient specificity of the comorbidity and multimorbidity definitions and, as a result, confusion in the use of these terms. Most authors are unanimous that the “core” of multimorbidity is presence of more than one disease in a patient. These coexisting diseases can be pathogenetically interconnected and non-interconnected. Regardless, the degree of multimorbidity always affects prognosis and quality of life.

The protection of the environment and people’s health from negative influences of the pollution of air as a medium of the environment requires constant observing of the air quality in accordance with international standards, the analysis of emission and imission of polluting matters in the air, and their connection with the sources of pollution. Having in mind the series of laws and delegated legislations which define the field of air pollution, it is necessary to closely observe these long-term processes, discovering cause-and-effect relationships between the activities of anthropogenic sources of emission of polluting matters and the level of air degradation. The relevant evaluation of the air quality of a certain area can be conducted if the level of concentration of polluting matters characteristic for the pollution sources of this area is observed in a longer period of time. The data obtained by the observation of the air pollution are the basis for creation of the recovery program of a certain area. Vranje is a town in South Serbia where there is a bigger number of anthropogenic pollution sources that can significantly diminish the air quality. The cause-and-effect relationship of the anthropogenic sources of pollution is conducted related to the analysis of systematized data which are in the relevant data base of the authorized institution The Institute of Public Health Vranje, for the time period between the year of 2012. and 2017. By the analysis of data of imission concentrations of typical polluting matters, the dominant polluting matters were determined on the territory of the town of Vranje, the ones that are the causers of the biggest air pollution and the risk for people’s health. Analysis of the concentration of soot, sulfur dioxide and nitrogen oxides indicates their presence in the air of Vranje town area in concentrations that do not exceed the permitted limit values annually. The greatest pollution is caused by the soot content in the air, especially in the winter period when the highest number of days with the values above the limit was registered. By perceiving the influence of natural and anthropogenic factors, it is clear that the concentration of polluting matters can be decreased only by establishing control over anthropogenic sources of pollution, and thus it can be contributed to the improvement of the air quality of this urban environment.
