This study explores structural modifications for reducing train-induced vibrations in timber buildings by modifying the building layout. A parameter study was conducted using a semi-analytical ground model coupled with a finite element structural model. The train load was modeled as a stationary oscillating point load of unit magnitude, applied on the ground surface. The analyzed frequency range,

Som en reaktion på Rysslands fullskaliga invasion av Ukraina har EU och allierade G7-länder infört omfattande sanktioner riktade mot rysk olja och petroleumprodukter. För att kringgå dessa sanktioner har Ryssland i allt större utsträckning förlitat sig på en parallell flotta – en så kallad skuggflotta – som har kommit att spela en betydande roll i finansieringen av den ryska krigföringen. SkuggfloIn response to Russia’s full-scale invasion of Ukraine, EU and allied G7 countries implemented extensive sanctions regimes targeting Russian oil and petroleum products. To circumvent these sanctions, Russia has increasingly relied on a parallel fleet operating without Western ties – a shadow fleet – which has come to play an important role in funding the Russian war effort. Shadow fleet vessels em

This study is part of a North West Europe (NWE) Interreg project called NWE-REGENERATIS that aims at the regeneration of past metallurgic sites and deposits through innovative circularity for raw materials. A novel geophysical methodology is developed to allow a 2D or 3D characterization of the recoverable metallic particles in terms of volume, type and grain sizes. We propose to integrate multi-m

Collective action problems emerge when individual incentives and group interests are misaligned, as in the case of climate change. Individuals involved in these problems are generally considered to have two options: contribute toward public solutions such as global warming mitigation or free ride. However, many collective action problems today involve a third option of investing in a “private solu

This article is based on ethnographic fieldwork carried out among what Lian Si (2009) has called China’s ‘ant tribe’, referring to the millions of unemployed Chinese college graduates who live in the outskirts of Beijing and to some extent share the predicament of China’s migrant workers. Education has been the main route to social mobility for centuries in China, but today college graduates are o

Children and adolescents exposed to traumatic events are at high risk of developing posttraumatic stress disorder (PTSD). With the rare exception of very young children, their PTSD presentations at the symptom level are similar to those of trauma-exposed adults, as are their patterns of psychiatric comorbidity, particularly for adolescents. Untreated, at least a significant proportion will carry o

This entry offers a short description of basic research questions, different theories, and topics in lexical semantic research. At the beginning, it states five fundamental questions that all lexical semantics theories need to attend to in descriptions and explanations of their observations and findings. A brief presentation of past and present theoretical approaches on lexical semantics follows,

Shared housing is a rather unusual phenomenon in Sweden. However, due to the decreasing availability of affordable housing and a large share of single-person households in urban areas, sharing is on the rise and new forms of shared housing have entered the market. By analysing how shared housing overlaps with existing patterns of socioeconomic segregation and by interviewing developers of diverse

During times of crisis, such as the COVID-19 pandemic, policymakers and the public reveal a strong preference for fairness in pricing even when that would reduce efficiency. For example, they support the application of price gouging laws that prevent prices for necessities from skyrocketing but probably also dampen incentives for firms to produce more and alleviate the shortage. More generally, a

Emmer (1993) claimed creativity to be a bridge between art and mathematics exemplified (www. olats.org/colloque/textes/texte7.shtml) in his traveling exhibition The Eye of Horus: Art and Mathematics (Emmer, 1990). A shared language is needed to make bridges between science, art and metaphysics (Thiessen, 1998). Scientific phenomena and concepts need to be possible to isolate for better understandi
