Reducing the heterogeneity of technical lignin is essential to obtain predictable and high-performance polymeric materials that are suitable for high-value applications. Organic solvents with different polarities and solubilities can be used to fractionate lignin and reduce the complexity and diversity of its chemical structure. Among the various solvents and solvent mixtures, acetone-water mixtur
Purpose: This paper aims to identify critical factors that influence small and medium-sized enterprise (SME) suppliers’ involvement in their customers’ product development and contrast these with the factors identified from the customer perspective. Design/methodology/approach: A multiple case study approach was used, including four companies. Data were collected through 32 semi-structured intervi
Develops the Black feminist concept of reproductive justice further in critical dialogue.Includes case studies and perspectives from Sweden, Nicaragua, Poland, Taiwan.Focuses on the historical and contemporary interplay between the state and the pro- abortion/anti-abortion movements.
Stupidity is generally thought of as a hindrance to learning: an epistemic vice that stands in the way of knowledge and understanding. In this article, I challenge this idea by exploring some of the meanings of stupidity that place it in a positive relation to learning. In this light, the article discusses two notions of stupidity: stupidity as unfinished thought and stupefaction through study. I
Poststructuralist perspectives need to be reconciled with political economic readings of urban globalization. One approach complements the other: the enactment of distantiated circuits and the territorialization of flows occur within existing geographies of uneven development while contingently reproducing or reshaping such spatial conditions of possibility. We argue that broadening the realm of c
Contemporary hybrid zones act as natural laboratories for the investigation of species boundaries and may shed light on the little understood roles of sex chromosomes in species divergence. Sex chromosomes are considered to function as a hotspot of genetic divergence between species; indicated by less genomic introgression compared to autosomes during hybridization. Moreover, they are thought to c
We conducted an extensive geophysical field campaign using ground-penetrating radar (GPR) and electrical resistivity tomography (ERT) in a former military area at the archaeological site of Nora (South-Western Sardinia). The purpose was to identify a Phoenician, and then Punic and Roman, necropolis of considerable interest, subject of a long-term investigation and currently under excavation. In th
Ramjet propulsion is commonly preferred to power supersonic and hypersonic vehicles for cruising faster than Mach 3. This is an elegant solution owing to the lean architecture which does not embody any rotating parts. Although the geometry of the engine is simple as compared to turbine based configurations, the flow physics through the engine duct is quite complex and the flow speeds modulate betw
Supply chain visibility (SCV) has been gaining recognition in recent years as a key factor for achieving analytical capabilities and improving supply chain performance. However, levels of SCV implementation lag behind current technological advances. This research was motivated by the lack of visibility in inbound logistics, which limits the possibility of managing deviation, in particular concerni
To improve the power handling capability at ground stations of a 5.8-GHz solar space power satellite using microwave power transmission, a power charge-pump meta-semiconductor field-effect transistor (MESFET)-based rectifier is presented in this article. Unlike conventional microwave Schottky diodes, diode-connected MESFETs, whose nonlinear characteristics help them to have a unique current&#x
Background: Population-based register data could be used to improve our knowledge of patients surgically treated for foot and ankle disorders. The quality register Swefoot was recently created to collect surgical and patient-reported data of foot and ankle surgery. This manuscript aims to describe the development and current use of the register. Methods: The development of Swefoot started in 2014
Abstract in ItalianUn’accesa e radicale tensione nelle scienze cognitive è quella tra il cognitivismo e il cosiddetto approccio delle quattro E (Embodied, Enactive, Embedded e Extended). La mancanza di una riflessione aperta e sostanziale sul lavoro teorico ed empirico proposto dall’approccio opposto appare problematica da entrambe le parti. Il presente contributo analizza a fondo le evidenze empiIn philosophy and cognitive science, the tension between cognitivism and the 4E-Cognition approach is both deep and polarizing. A lack of serious engagement with the theoretical and empirical work generated by the opposing framework seems problematic on both sides. In this paper, we closely discuss data on early socio-cognitive development produced by an influential nativist current of thought in
In this article, we investigate public support for eco-social policies combining goals of social justice and ecological sustainability. Eco-social policies contribute both to providing a social floor or redistributing resources to where they are needed and to respecting an ecological ceiling by keeping human activities within ecological limits. We discuss five such policies and highlight arguments
Blood-based markers (BBMs) have recently shown promise to revolutionize the diagnostic and prognostic work-up of Alzheimer's disease (AD), as well as to improve the design of interventional trials. Here we discuss in detail further research needed to be performed before widespread use of BBMs. We already now recommend use of BBMs as (pre-)screeners to identify individuals likely to have AD patholo
