Assessing the ability of white-rot fungi to tolerate polychlorinated biphenyls using predictive mycology
The aim of the present study was to assess the ability of different white-rot fungi to tolerate polychlorinated biphenyls (PCBs) using predictive mycology, by relating fungal growth inhibition to ligninolityc enzyme secretion. Fungal strains were grown in the presence of PCBs in solid media and their radial growth values were modelled through the Dantigny-logistic like function in order to estimate the time required by the fungal colonies to attain half their maximum diameter. The principal component analysis (PCA) revealed an inverse correlation between strain tolerance to PCBs and the laccase secretion over time, being laccase production closely associated with fungal growth capacity. Finally, a PCA was run to regroup and split between resistant and sensitive fungi. Simultaneously, a function associated with a model predicting the tolerance to PCBs was developed. Some of the assayed isolates showed a promising capacity to be applied in PCB bioremediation. Abbreviations: Polychlorinated biphenyls (PCBs), white-rot fungi (WRF).Fil: Sadañoski, Marcela Alejandra.

Benefits of Acceptance and Commitment Therapy (ACT) for Chronic Pain
Chronic pain is a common experience for people and can be difficult to manage. However, there are many evidence-based and effective psychological treatments for chronic pain to help people improve their lives. One of these is acceptance and commitment therapy, or ACT. ACT teaches how to accept pain and live a life full of meaning and quality, with pain. It helps individuals increase their quality of life through mindfulness-based methods, experiential processing, and a focus on values, goals, and actions. ACT has been shown to be effective in reducing pain and improving pain management and personal well-being. Consult the resources at the end of the fact sheet for additional learning on this topic
Myten om den vältränade kroppen: kvinnliga atleters upplevelse av femininitet inom gymvärlden och hur deras kroppar passerar och orienteras i olika rum
The purpose of this qualitative study is to explore female athletes experiences of being a women in a space that has historically been dominated by men: the gym. Using Sara Ahmed’s idea of orientation and spatiality it analyzes how sportswomen moves through different positions in different rooms, the position as a woman and the position as an athlete. The concept of orientation examines how different types of bodies either fits in and ”feels as home” in a room while other bodies are hindered and seen as misplaced. With Beverley Skeggs understanding of femininity this thesis elaborates on how the notion of femininity plays a role in how some women are seen as feminine while some women are considered lacking in femininity by not looking or performing normative femininity. Struggling with the two different positions either as women or an athlete, the women of this study shows us how norms of masculinity and femininity still plays a big part in who is seen as an athlete and whom is just considered ”strong for a woman”
Social media battle for attention: opinion dynamics on competing networks
In the age of information abundance, attention is a coveted resource. Social
media platforms vigorously compete for users' engagement, influencing the
evolution of their opinions on a variety of topics. With recommendation
algorithms often accused of creating "filter bubbles", where like-minded
individuals interact predominantly with one another, it's crucial to understand
the consequences of this unregulated attention market. To address this, we
present a model of opinion dynamics on a multiplex network. Each layer of the
network represents a distinct social media platform, each with its unique
characteristics. Users, as nodes in this network, share their opinions across
platforms and decide how much time to allocate in each platform depending on
its perceived quality. Our model reveals two key findings. i) When examining
two platforms - one with a neutral recommendation algorithm and another with a
homophily-based algorithm - we uncover that even if users spend the majority of
their time on the neutral platform, opinion polarization can persist. ii) By
allowing users to dynamically allocate their social energy across platforms in
accordance to their homophilic preferences, a further segregation of
individuals emerges. While network fragmentation is usually associated with
"echo chambers", the emergent multi-platform segregation leads to an increase
in users' satisfaction without the undesired increase in polarization. These
results underscore the significance of acknowledging how individuals gather
information from a multitude of sources. Furthermore, they emphasize that
policy interventions on a single social media platform may yield limited
impact.Comment: 13 pages, 7 figure
Scaling violation and shadowing corrections at HERA
We study the value of shadowing corrections (SC) in the HERA kinematic region in the Glauber{ Mueller approach. Since the Glauber{Mueller approach was proven in perturbative quantum chromodynamics (QCD) in the double-logarithmic approximation (DLA), we develop the DLA approach for the deep inelastic structure function which takes into account the SC. Our estimates show small SC for F2 in the HERA kinematic region while they turn out to be sizable for the gluon structure function. We compare our estimates with those for gluon distribution in leading order (LO) and next to leading order (NLO) in the DGLAP evolution equations
