Numerous sections of the Mureş River vary in terms of the abundance of nitrates, ammonia, and orthophosphates; and of correlated lotic sediment bacterial microbiome structures in terms of both diversity and abundance. This highlights the great versatility of microbiomes in being influenced by the physical-chemical characteristics of environments and their spatial changes. Bacteria microbiomes exhibit dynamic and shifting potential and significant tendencies toward self-organization and self-adaptation. These typical features represent an essential ecologic basis for lotic systems having to do with the use and reuse of various kinds of environmental resource as chemical substances. In this respect, trophic processes assure the river ecosystem optimum health ecologic status dynamic and trend, to be reached. The flexibility of shifting bacterial microbiomes is crucial in maintaining this ecological context’s vital role in biogeochemically sustaining other taxonomic groups, which are spatially and temporally continuous. This is especially important for nutrient cycle processes, even for rivers with high levels of negative human impact, in promoting a functional lotic system.

In this study we propose the establishment of theological rules (qawāʿid iʿtiqādiyya) similar to the jurisitic rules (qawāʿid fiqhiyya) which have for centuries been very important to Islamic jurisprudence, and which play a vital role in jurisprudence and uṣūl al-fiqh. The present article takes the second sura of the Qur'an, Sūrat al-Baqara, as a case study, identifying three fundamental principles in this sura: (i) man is honoured (al-insān mukarram), (ii) the Resurrection is a reality (al-baʿth ḥaqq) (iii) belief in all prophets is obligatory (al-īmān bi-kāfat al-anbiyāʾ wājib). These three rules are emphasised and reiterated in many parts of the sura, to a greater extent than any other principle. This study calls for other scholars to consider this proposition and develop it further.

As the most historically and culturally valuable city district in Nanning, Xingning Block has gradually formed its own unique color characteristics and architectural style in the slow process of urban historical development, showing the unique local customs and architectural features. However, restricted by the specific development conditions, many undesirable aspects can be found in the overall architectural landscape color of some nodes on the block, such as lack of systematic planning, poor material matching, messy building color, as well as various challenges of contemporary social development to the architectural environmental color on the block.The architectural environmental color of urban traditional blocks is an important part of the specific history, culture and spirit of the times of a city, which plays a vital role in the development and change of the city. Therefore, how to effectively and reasonably do a good job in sustainable urban planning and development is an issue that must attract the attention of competent authorities at all levels, scientific research institutions and planning practitioners.

AbstractThis paper examines the role of values in transformations toward sustainability. Values, generally defined as what people deem to matter, are increasingly gaining interest in and outside of academia. For example, sustainability aligns with specific values such as dignity, equality, safety, and harmony for people and nature. However, current approaches to values are mind-matter dualistic, and therefore failing to honor the inherently dynamic relations of socio-ecological systems. Drawing on new materialism, I explore values as part of the relations that make this world and propose to consider values as material-discursive practices. Ethnographic fieldwork was done in 2017 with coffee producers in Burundi who aimed to transform production by caring for the coffee and people that grow it. Based on interviews and participatory observation, I present how values were integral to transforming the relational aspects of coffee production. In this study, values of togetherness, care, dignity, and faith were dominant and were found to reconfigure the socio-ecological system of coffee production. I argue that values are inseparable from, and hence co-productive of, the material world that we experience and play a vital role in sustainability transformations.

This paper presents a systematic function recommendation process (FRP) to recommend new functions to an existing product and service. Function plays a vital role in mapping user needs to design parameters (DPs) under constraints. It is imperative for manufacturers to continuously equip an existing product/service with exciting new functions. Traditionally, functions are mostly formulated by experienced designers and senior managers based on their subjective experience, knowledge, creativity, and even heuristics. Nevertheless, against the sweeping trend of information explosion, it is increasingly inefficient and unproductive for designers to manually formulate functions. In e-commerce, recommendation systems (RS) are ubiquitously used to recommend new products to users. In this study, the practically viable recommendation approaches are integrated with the theoretically sound design methodologies to serve a new paradigm of recommending new functions to an existing product/service. The aim is to address the problem of how to estimate an unknown rating that a target user would give to a candidate function that is not carried by the target product/service yet. A systematic function → product recommendation process is prescribed, followed by a detailed case study. It is indicated that practically meaningful functional recommendations (FRs) can indeed by generated through the proposed FRP.

Wetlands play a number of roles in the environment, which are also considered the most biologically diverse of all ecosystems. Utilizing RS and the GIS software, remote datum were matched and classified. By these transactions, the temporal and spatial changes of wetland landscape are explored in Wuhu, combining qualitative analysis and quantitative methods. This paper analyzed the time-spatial revolution process which indicated that, firstly the area of wetland reduced rapidly from remote sensing image in 1988, 2001 and 2005, secondly the exterior of urban changed acutely and the interior were protected well in view of spatial pattern. Moreover, driving force factors were pointed out. Human activities, especially urbanization were the main causes of wetlands degradation. Simultaneity, the development of farming, the construction of infrastructure and nature were important factors. Owing to rapid economic development and urban sprawling, wetlands are encountering threaten to be converting to other land uses. Thus, the paper provides policy advices for wetland conservation and urban planning toward sustainable development.

Today, suburbs and urban fringes are pivotal places for understanding contemporary urban transformations because the majority of the world’s urban population live in suburbs. Suburbanization (i.e. the process of combining the non-centric population, economic growth, and spatial expansion) and suburbanisms (suburban ways of living) are key concepts for observing these transformations, framed under the umbrella of the post-suburban theoretical framework. This paper relies on a post-suburban standpoint as it enables the complexity of the diverse transformations at the urban edges to be addressed. On such basis, this paper discusses the outcomes of a qualitative case study conducted on the most recently built neighbourhood of Fiano Romano, a suburb of Rome that has faced a number of socio-spatial transformations over the past two decades. The study illustrates the diverse complexities related to the provision of welfare services and public amenities such as water and social infrastructures. In so doing, the article unfolds the shape of a ‘new suburbia’ characterized by emerging socio-spatial changes that lie in processes of peripheralization, which characterize many contemporary post-Fordist suburban areas, especially at the present time of the coronavirus crisis. The article points out the centrality of suburban ways of living in studying issues involving both spatial planning and governance of welfare. Furthermore, the article highlights the idea that new inequalities and deprivations are taking place in diverse suburban areas, and that such aspects deserve further governance agendas able to meet the suburban social demands that differ from traditional urban vulnerabilities.

Phytoplankton play a vital role as primary producers in aquatic ecosystems. One common approach to classifying phytoplankton is fluorescence excitation spectroscopy, which leverages the variation in types and concentrations of pigments among different phytoplankton taxonomic groups. Here, we used a fluorescence imaging photometer to measure excitation ratios (“signatures”) of single cells and bulk cultures of seven differently pigmented phytoplankton species as they progressed from nitrogen N-replete to N-depleted conditions. Our objective was to determine whether N depletion alters the fluorescence excitation signature of each species and, if so, how quickly they recover when N (as nitrate) was resupplied, because these factors affect our ability to classify the species correctly. Of the seven species studied, only Proteomonas sulcata, a marine cryptophyte, showed measurable changes in single-cell fluorescence excitation ratios and bulk fluorescence excitation spectra. These changes were likely due to decreases in the cellular concentration of phycoerythrin, a N-rich pigment, as N became scarce. Within 3 h of resupply of N, fluorescence signatures began returning to pre-depletion values and were indistinguishable from N-replete cells by 80 h after resupply. These data suggest that our classification approach is robust for non-PE containing phytoplankton. PE-containing phytoplankton might exhibit systematic changes in their signatures depending on their level of N depletion, but this could be detected and the phytoplankton re-classified following a few hours of incubation in N replete conditions.

This study aims to describe Sufistic-based Kiai leadership's role in shaping Santri character at the Pesantren Nurul Jadid Paiton Probolinggo. This research is a case study qualitative approach, with Kiai as the subject. We collected data using interview, documentation, and observation techniques, then analyzed using reduction techniques, presenting data, and drawing conclusions. The results showed that the Sufistic-based Kiai's leadership had an essential role in fostering the character of the Santri. The study results indicate that the Sufistic-based Kiai leadership has a vital role in promoting the surface of the Santri. Kiai is a person who gives influence in building character with Uswah (Modelling). This study also found that the factors that influence low morale are that Santri has a common understanding of the latest technological developments. In Sufistic-based leadership, there are four things that a leader must possess: 1) The Tawasuth, 2) The nature of I'tidal, 3) The Tawazun, and 4) The Tasamuh.

This paper presents the assessment of the impact of coal ash and slag from the ?Maljevac? dump on the quality of water of Paleski Creek, Montenegro. The obtained results confirm the negative influence of surface and groundwater from the dump on the water from the Paleski Creek. The results obtained by testing of the water samples, collected from Paleski Creek upstream of the dump, indicate that the water is qualified to be used for drinking, after simple physical treatment and disinfection. The results obtained for the water samples collected from the Paleski creek downstream from the dump indicate that the water could be safe for drinking only after the treatment that requires an intensive physical, chemical and biological processing, including some extended treatment.
