We here report on the synthesis and polymerization of nitrile-containing methacrylate monomers, prepared via straightforward nitrilation of the corresponding lignin-inspired aldehyde. The polymethacrylates reached exceptionally high glass transition temperatures (Tg values), i.e., 150, 164, and 238 °C for the 4-hydroxybenzonitrile, vanillonitrile, and syringonitrile derivatives, respectively,

Organizations interact with their stakeholders to a large degree through social media such as Facebook, Instagram, Twitter and YouTube ( Bellucci & Manetti, 2017). There are indications that there is an increase in the use of emotional language in organizations’ external communication in social media over time, since this is thought to generate more stakeholder engagement (Weinryb et al, 2021)

The dosimetry of cone beam computed tomography (CBCT) is not fully elaborated yet, and some of these systems presents dose-area-product (DAP) values after an examination rather than, as in the case of traditional CT, the doselength- product (DLP). The purpose of this study was to provide a reproducible and straight-forward method for DLP measurements on CBCT, as well as to validate a tool for estiThe dosimetry of cone beam computed tomography (CBCT) is not fully elaborated yet, and some of these systems presents dose-area-product (DAP) values after an examination rather than, as in the case of traditional CT, the doselength- product (DLP).

Cities, and more importantly urban neighborhoods, are key sites of infrastructure provision with direct links to social and environmental concerns. They are increasingly seen as sites of strategic action in transitions toward sustainability and resilience, and offer big opportunities for fundamental societal change. The framing of neighborhood-level problems and their solutions, governance process

Objective: The purpose of this study was to explore a novel method forbrain tissue differentiation using quantitative analysis of multiphase computedtomography (CT) angiography (MP-CTA) on spectral CT, to assesswhether it can distinguish underperfused fromnormal tissue, using CT perfusion(CTP) as reference.Methods: Noncontrast CT and MP-CTA images from 10 patients wereanalyzed in vascular regions

To mitigate wild bee declines, it is important to understand the separate and joint effects of parallel losses of semi-natural habitats containing flower resources and increases in transient flower resources provided by mass-flowering crops. Since mobility may affect how bee species cope with these changes, they may also affect competitive interactions and thus community composition. We focused onTo mitigate wild bee declines, it is important to understand the separate and joint effects of parallel losses of semi-natural habitats containing flower resources and increases in transient flower resources provided by mass- flowering crops.

Ongoing pollinator declines threaten the production of many entomophilous crops. Recent reports that yields of animal-pollinated crops in India are increasing less than pollinator-independent ones suggest the occurrence of pollen limitation. We experimentally evaluated if production of the common food crop chilli benefits from insect pollination and if crop production is constrained by lack of pol

Brief review article on the poetry collection "Dagar av liv" ("Days of life") by Swedish writer Gunnel Arvidsson (b. 1948).

Alzheimer’s disease (AD) is the most common cause of dementia, costing about 1% of the global economy. Failures ofclinical trials targeting amyloid-βprotein (Aβ), a key trigger of AD, have been explained by drug inefficiency regardlessof the mechanisms of amyloid neurotoxicity, which are very difficult to address by available technologies. Here, wecombine two imaging modalities that stand at oppos

Recent studies indicate a crucial role for neuronal glycogen storage and degradation in memory formation. We have previously identified alpha-amylase (α-amylase), a glycogen degradation enzyme, located within synaptic-like structures in CA1 pyramidal neurons and shown that individuals with a high copy number variation of α-amylase perform better on the episodic memory test. We reported that neuron

Aggregation of α-synuclein is associated with neurodegeneration and a hallmark pathology in synucleinopathies. These aggregates are thought to function as prion-like particles where the conformation of misfolded α-synuclein determines the traits of the induced pathology, similar to prion diseases. Still, little is known about the molecular targets facilitating the conformation-specific biological

Sweden has set ambitious goals concerning future sustainable cities. Solar energy plays a vital role in this transformation, since it directly relates to our health and well-being, on-site renewable energy production, economic activity, and social interaction. Therefore, prioritizing solar access already in the urban design phase is important to create equal possibilities for everyone living and w

Light stability of different spray dried microencapsulated powders containing the natural colorant bixin was evaluated for 30 days. The encapsulating materials evaluated were sucrose, maltodextrin, and mixtures including gum arabic and pectin as encapsulation enhancers. The photostability of two sets of encapsulated material was compared: one containing purified bixin, and one being an annatto ext

Access to metabolic information in vivo using magnetic resonance (MR) technologies has generally been the niche of MR spectroscopy (MRS) and spectroscopic imaging (MRSI). Metabolic fluxes can be studied using the infusion of substrates labeled with magnetic isotopes, with the use of hyperpolarization especially powerful. Unfortunately, these promising methods are not yet accepted clinically, where

This book offers insights on politics and ethics of representation that are relevant to researchers concerned with struggles for justice. It takes moments of discomfort in the qualitative research process as important sites of knowledge for exploring representational practices in critical research.The Politics and Ethics of Representation in Qualitative Research draws on experiences from research

This chapter highlights the importance of collective conversations regarding how to navigate the complexity of positions, roles, stakes, interests and feelings that most researchers experience. The author explores a conversational format as a way of writing about affective reflexivity. The chapter departs in a PhD project focusing on the lived experiences of variations of sex characteristics, in o

While Africa is one of the most promising continents in the world, it is facing mounting challenges to sustainable development in terms of disaster risk, climate change, environmental degradation and demographic and socioeconomic processes. Societies are thus increasingly conceived as having to be resilient to safeguard what they value over time. However, for resilience to have any practical meani
