Plant-symbiotic Trichoderma fungi attack microorganisms by secreting antibiotic membrane-permeabilising peptaibols such as alamethicin. These peptaibols also permeabilise plant root epidermis plasma membranes (PMs), but mild pretreatment with Trichoderma cellulase activates a unique cellulase-induced resistance to alamethicin (CIRA), via an unknown mechanism. We identify two Arabidopsis genes that
In the active exploration of novel biobased semicrystalline polyesters to replace petrochemical plastics, AB-type aromatic condensation polymerizations are relatively rarely investigated but gain growing attention due to the straightforward synthesis of AB-type monomers from diverse asymmetric biobased feedstocks. However, achieving high molecular weights through AB-type melt polycondensations is
We explore the challenges facing the current academic training of economists in small European countries such as Sweden. The monolithic focus on publishing in the top-five journals, which prioritizes methodological rigor over problem-driven research, is often a threat to social relevance and policy applicability. This limits pluralism, excludes many talented economists, and fails to prepare gradua
Philanthropy for gender causes is recognised as a rising yet understudied phenomenon, especially in the field of social policy. This chapter provides an overview of key interdisciplinary feminist debates on the philanthropic turn to gender equality and women's empowerment. It also presents significant trends, including funding flows towards SDG5, key actors, and geographical areas of investment, a
Over geologic time, biocalcification – the process by which marine organisms make calcium carbonate (CaCO3) – has reshaped climates, ocean life, and seawater chemistry. In particular, the evolution of coccolithophores, the largest group of nannoplankton and today’s most productive calcifiers, transformed ocean environments and the carbon cycle. Their origins, however, remain enigmatic. This is par
Purpose of Review: This paper aims to evaluate the burden of contact allergy caused by cosmetic products, identifying the key allergens involved and examining recent regulatory and diagnostic developments. The review addresses which substances commonly induce allergic contact dermatitis and how current trends and emerging allergens impact clinical practice. Recent Findings: Fragrances remain the m
This thesis addresses many issues surrounding the simple question: why have trams? With city populations exponentially growing alongside concerns over the environment and the economy, tramways have become a resurging form of sustainable transportation for municipalities. Once an endangered transportation mode, torn up and scrapped to make room for the age of cars, tramways are phoenix artifacts of
Purpose: To explore the association between marital status and testosterone, and cortisol serum levels in 119 healthy men aged 45 to 60 years representing the general population. Material and Methods: Data on men’s age, waist circumference, body mass index, smoking, alcohol consumption, and marital status were collected. Serum levels of LH, testosterone, and cortisol were also measured. Two groups
Säkerheten om demokratins robusthet har gett vika för en allmänt diagnostiserad demokratikris. Allt fler röster höjs för att försvara de demokratiska institutionerna mot dem som vill avskaffa dem på formellt demokratisk väg. Men för att värna demokratin, hävdas det, krävs paradoxalt nog att man håller tillbaka den demokratiska omvandlingen. I denna avhandling hävdas att denna ”demokratiska paradoCertainty about the robustness of democracy has given way to a widely diagnosed crisis of democracy. There are increasing calls to defend democratic institutions against those who seek their formally democratic abolishment. But safeguarding democracy, it is argued, paradoxically requires restraining democratic transformation. This dissertation argues that this ‘democratic paradox’ is misconceived.
We present a Lyapunov centre theorem for an antisymplectically reversible Hamiltonian system exhibiting a nondegenerate 1 : 1 or 1:-1 semisimple resonance as a detuning parameter is varied. The system can be finite- or infinite-dimensional (and quasilinear) and have a non-constant symplectic structure. We allow the origin to be a ‘trivial’ eigenvalue arising from a translational symmetry or, in an
The emergence of microbial antibiotic resistance is a central threat to global health, food security, and development. It has been shown that heavy metal pollution can give rise to microbial resistance to antibiotics, but how wide-spread this phenomenon is remains an open question that urgently needs filling to enable appropriate environmental risk assessments. Here, we determined whether long-ter
Soil microorganisms regulate the decomposition of organic matter. However, microbial activities can also be rate-limited by the resource in lowest supply. Arctic ecosystems are being exposed to pronounced climate warming, with arctic greening, treeline advance and shrubification resulting in increased plant-derived carbon (C) inputs to soils, and faster rates of decomposition releasing mineral nut
The political and institutional crisis in Brazil from 2015, fueled largely by corruption probes and lawfare, had severe repercussions within the Brazilian construction and energy sectors. While many international investors withdrew from Brazil in this period, Chinese investment surged. This article accounts for the particular characteristics of Chinese investments, such as sectorial complementarit
Background: Although telemedicine grew rapidly during the COVID-19 pandemic, instruments to assess general practitioners’ (GPs) attitudes and behavioral intentions to use it are scarce. In Sweden, the Physicians’ Attitudes and Intentions to use Telemedicine (PAIT) questionnaire was developed from the “theory of planned behavior” in 2019 and translated into English in 2022. Objective: The aim of th
In this study, a multiphysics model is presented that predicts creep in three months old concrete cylinders subjected to drying. The model includes concrete hydration, and a moisture transport model with relative humidity as the driving potential. These parameters are important to include in order to simulate creep. The model was implemented in the finite element software COMSOL Multiphysics. The
Mutations of Fused in sarcoma (FUS), a ribonucleoprotein involved in RNA metabolism, have been found associated with both familial and sporadic cases of amyotrophic lateral sclerosis (ALS). Notably, besides mutations in the coding sequence, also mutations into the 3′ untranslated region, leading to increased levels of the wild-type protein, have been associated with neuronal death and ALS patholog
