The mechanisms of entrapment, and the nanoscopic spatial distribution, of the residual mercury within nano-cast and amorphous porous media (pore sizes ∼1-100 nm) following high-pressure penetration have been studied. It has been shown that, even at the nanoscale, one of the same two principle mechanisms that have been observed previously in mercury porosimetry experiments on macroscopic glass pore

Geometrid moths, the second largest radiation of Lepidoptera, have been the target of extensive phylogenetic studies. Those studies have flagged several problems in tree topology that have remained unanswered. We address three of those: (i) deep nodes of Geometridae (subfamilies Sterrhinae + Larentiinae, or Sterrhinae alone as sister to all other subfamilies), (ii) the taxonomic status of subfamil

Practitioners and scholars are increasingly aware that an array of new actors, communication technologies, agendas and expectations are changing the institution of diplomacy. How diplomatic actors are known and experienced through their representation assumes an increasingly important, and uncertain, role. This article argues that these changes to the field should be considered in terms of the shi

Introduction Survival after out-of-hospital cardiac arrest (OHCA) remains low. Early recognition by emergency medical dispatchers is essential for an effective chain of actions, leading to early cardiopulmonary resuscitation, use of an automated external defibrillator and rapid dispatching of the emergency medical services. Aim To analyse and compare the accuracy of OHCA recognition by medical dis

Fiber composites are widely used for space applications such as antennas, solar panels and spacecraft support structures. This paper presents a combined electromagnetic and acoustic analysis of a triaxial carbon fiber weave structure, designed for ultra lightweight reflector antennas in satellite communication systems. The electromagnetic and acoustic performance of the structure are analyzed over

Popular Abstract in Swedish Alla kemikalier vi använder oss av och utsätter oss för påverkar både oss och den omvärld vi lever i. Under hela sin livscykel har de en påverkan på miljön, från de att man utvinner råmaterialen, när de tillverkas och när vi använder dem. Till och med efter att vi använt dem har kemikalierna en påverkan på miljön. Det gäller både schampot som följer med duschvattnet ut It is of at most importance that society reduces its impact on the environment. In the chemical industry the use of renewable resources will play a fundamental role in the transition to more sustainable chemical products. Also industrial biotechnology, i.e. the use of enzymes to convert raw material into valuable chemicals at low temperatures, leads to more sustainable processes. The research pres

In this work we present the quasi-steady state simulation of a regenerative organic Rankine cycle (ORC) integrated in a passenger vessel, over a standard round trip. The study case is the M/S Birka Stockholm cruise ship, which covers a daily route between Stockholm (Sweden) and Mariehamn (Finland). Experimental data of the exhaust gas temperatures, engine loads, and electricity demand on board wer

Research question: "How do young women construct and perform aspirational identities through the Clean Girl aesthetic on digital platforms?" Purpose: The purpose of this study is to expand the understanding of how trendy aesthetics on digital platforms like TikTok shape users’ identity construction and self-performance. Theoretical perspective: Two main theoretical fields, aspirational

When I intend to J, I may be wrong about what I intend but not about who intendsit. In this sense, action intentions appear immune to error. A standard explanationof this immunity is that the subject of the intention is not represented in the contentof the intention in the first place. When I think that we intend to J, it seems obviousthat I can misjudge who ‘we’ are. This may seem to indicate tha

An implementation to convert one of Adobes Flash file-format (xfl) to HTML5 has been created. The problems that need to be solved for completion of this converter are. What programming language should be used that is suitable for the application and locating some form of documentation of the file-format xfl. Javascript was chosen for implementation, but a usable documentation of xfl was not to be

This paper uses data from a recently-released survey pertaining to individuals in urban locations in 2007 to estimate rates of return to education in China. In doing so, previous estimates in the empirical literature are updated by five years. The key issue under consideration is whether the private incentive to spend time and money on education has increased over the course of China’s economic tr

The main controversy in international law the past decades has been the approach to a non-international conflict exposing civilians to threats of genocide or mass atrocities. One corner stone of international law is the protection of a state and its internal affairs, the principle of non-intervention; another one is the protection of human rights. During the 1990s, the two principles were seen as

Line segments are ubiquitous in our human-made world and are increasingly used in vision tasks. They are complementary to feature points thanks to their spatial extent and the structural information they provide. Traditional line detectors based on the image gradient are extremely fast and accurate, but lack robustness in noisy images and challenging conditions. Their learned counterparts are more

There is great interest in measuring immune function in wild animals. Yet, field conditions often have methodological challenges related to handling stress, which can alter physiology. Despite general consensus that immune function is influenced by handling stress, previous studies have provided equivocal results. Furthermore, few studies have focused on long-lived species, which may have differen

Understanding and addressing the complex societal sustainability challenges requires applying novel approaches, devising innovative assessment frameworks, and adopting methods and tools from other research fields. Dr Jagdeep Singh has been conducting inter- and trans-disciplinary research on these challenges impacting academia and society. He has pursued university degrees in Electrical Engineerin
