This paper establishes an efficient and convenient method for improving the salt tolerance of microbial flora in MFCs, which is of great significance for the application of MFCs in high-strength wastewater treatment. Being 'with woman' is a fundamental concept of midwifery philosophy. Minimal evidence explicates ways this important construct is learned or taught. This paper reflects one part of a larger study and explored midwives' experiences of learning and teaching related to the phenomenon of being 'with woman'. Using a descriptive phenomenological approach, 31 midwives working in a variety of models in Western Australia were interviewed to explore the phenomenon of being 'with woman'. Rich descriptions of how midwives learned and taught others to be 'with woman' were obtained. Descriptive phenomenology is useful in revealing features of the phenomenon through description of lived experiences of purposively sampled participants. Giorgi's method was used to analyse data from the two main interview questions. The themes for learning to be 'with woman' were observing midwives; inspirational leaders; learning from the women; a variety of experiences enhances learning; and, develops over time. The themes for teaching being 'with woman' were, approaches for teaching; teaching is implicit; reliance on observation, comprehension and assimilation. Insights into the learning and teaching of practices supported by professional philosophy offer educators and leaders new knowledge and ways to enhance the transfer of knowledge and skills of being 'with woman'. In the construction industry, reuse and recycling strategies help reducing waste, saving energy and cutting down emissions by converting construction and demolition (C&D) waste into resources. This study proposes a novel framework to guide the life cycle assessment (LCA) of concrete structures with reuse and recycling strategies. The material flow in recycling strategies is clarified explicitly. A new definition of degradation rate is introduced to set a nonlinear allocation rule for reusable components based on the durability feature of concrete structures. Reusable rate and replacement percentage are adopted to provide a convenient way to adjust the type and level of the strategies. As a result, a unified system boundary and corresponding indicator functions can be established for various strategies, combing the closed-loop analysis and the open-loop analysis. In the case study, design for deconstruction (DfD) and recycled aggregate concrete (RAC) are taken as examples of reuse and recycling strategies, respectively. With the proposed framework, LCA of various strategy combinations are conducted considering the global warming potential (GWP) and abiotic depletion potential (ADP) indicators. Results show that the maximal environmental benefit of DfD is 1.8-2.8 times compared to that of RAC. When adopting DfD and RAC simultaneously, the environmental benefit level of each strategy will decline, whereas the overall benefits will be increased. LCA with the proposed framework avoids some assumptions in conventional LCA and provides more reliable results for various strategy combinations. Biochar is a pyrogenous organic material resulting from the pyrolysis of organic residues, which is attracting the interest from researchers and farmers for its potential to sequester carbon and its use as soil ameliorant. Pyrolysis conditions and feedstock determine the properties of the biochars produced. In order to understand the relationship between these variables we analysed in detail the physical, chemical and surface characteristics of biochars produced from three contrasting agronomic residues abundantly generated in South Spain, such as rice husk (RH), olive pit (OP) and pruning remains of olive trees (mainly composed of olive branches and leaves; OB), using a temperature range from 350 to 600 °C and residence times from 0.5 to 4 h. High pyrolysis temperature (600 °C) and time resulted in the greatest pH and C content in the biochars. In general, elemental composition and ash content were dependent on the type of organic waste used as feedstock. 13C Nuclear Magnetic Resonance Spectroscopy and thermal (TG-DSC) analyses showed that temperatures ≥500 °C are needed to achieve a high degree of aromatization of the chars. Micro-computed tomography and field emission scanning electron microscopy revealed that the structure of RH was preserved during the pyrolysis process, favouring a greater porosity for these biochars. These data are very useful for the production of stable biochars obtained from residual biomass, maximising the value of residual biomass resources. These biochars show physical and chemical properties, such as adequate pH, high water retention capacity or high porosity, of interest for their use as soil amendments. Penicillin V mycelial residue (PMR) is a byproduct of the pharmaceutical industry and may be disposed through land application after alkaline-thermal treatment. However, the efficacy of alkaline-thermally treated PMR in soil amelioration and the potential contamination risk caused by introduced penicillin V are poorly understood. Berzosertib supplier In this study, soil pH, the contents of organic matter, available phosphorus, available potassium were measured to study the effect of alkaline-thermally treated PMR on soil fertility; the numbers of culturable microorganisms and the activities of enzymes, which not only reflect the decomposing ability of organic matter but also monitor the ecological suppression in soil ecosystem, were also investigated; moreover, the persistence of introduced penicillin V and the variation of antibiotic resistance genes (ARGs) in soil were examined to evaluate the resulting antibiotic resistance risk. The results indicated that the pH and the content of available potassium in amended soil with treated PMR profoundly improved. In addition, the culturable microorganisms and enzymes were not inhibited throughout the incubation of treated PMR in soil. The stability of treated PMR in soil relatively completed after 43 days. More importantly, the penicillin V derived by treated PMR rapidly depleted within 3 days, which suggested a relatively low environmental persistence. The treated PMR did not enrich the ARGs detected in soil, demonstrating that the addition of treated PMR might not trigger the antibiotic resistance risk in the short-term in soil. In conclusion, our results concluded that alkaline-thermally treated PMR is available for soil application.
