Due to improved laboratory techniques, touched surfaces and items are increasingly employed as sources of forensic DNA evidence. This has urged a need to better understand the mechanisms of DNA transfer between individuals. Shedder status (i.e. the propensity to leave DNA behind) has been identified as one major factor regulating DNA transfer. It is known that some individuals tend to shed more DN

Purpose: Hypoxia (low oxygen) is a common feature of solid tumors that has been intensely studied for more than six decades. Here we review the importance of hypoxia to radiotherapy with a particular focus on the contribution of hypoxia to immune responses, metastatic potential and FLASH radiotherapy, active areas of research by leading women in the field. Conclusion: Although hypoxia-driven metas

This paper is about the socio-technical findings of a project that was carried out for an organisation in the educational sector. The main aim of the project was to explore the possibilities of developing a mobile Augmented Reality authoring tool that educators would use to create AR experiences in attempt to improve their teaching methods. A novel ‘solution’ was designed and prototyped, which ini

Background: Community services for Swedish people with intellectual disability (ID) are intended to support self-determination and integrity. Legislation does not allow the use of restrictive or coercive measures. Aim: The aim of this study is to identify the extent of, rationale for, and strategies staff believe would reduce the use of restrictive measures in group homes and daily activities serv

In 2009, the International Soil Moisture Network (ISMN) was initiated as a community effort, funded by the European Space Agency, to serve as a centralised data hosting facility for globally available in situ soil moisture measurements . The ISMN brings together in situ soil moisture measurements collected and freely shared by a multitude of organisations, harmonises them in terms of units and sam

Every year novel biologically active compounds are designed as antitumor agents. This review covers and highlights some of the most important findings described during 2018–2020 to appoint the benefits and drawbacks regarding the activity and toxicity of the metal-based cancer drug candidates. We review new multi-action platinum(IV) prodrugs and other metal complexes with high chemotherapeutic pot

At their core, the UN Climate Change conferences known as “COPs” are the primary international venue for negotiating how countries should act and cooperate to avoid dangerous climate change. The 2015 Paris Agreement is its most recent notable success. Although the climate negotiations are a state government-led process, the UNFCCC (United Nations Framework Convention on Climate Change) community h

Particles beyond the Standard Model (SM) can generically have lifetimes that are long compared to SM particles at the weak scale. When produced at experiments such as the Large Hadron Collider (LHC) at CERN, these long-lived particles (LLPs) can decay far from the interaction vertex of the primary proton–proton collision. Such LLP signatures are distinct from those of promptly decaying particles t

The suppression of chaos in quantum reality is evident in quantum scars, i.e. in enhanced probability densities along classical periodic orbits. They provide opportunities in controlling quantum transport in nanoscale quantum systems. Here, we study energy level statistics of perturbed two-dimensional quantum systems exhibiting recently discovered, strong perturbation-induced quantum scarring. In

Heterostructures of pentacene (PEN) and buckminsterfullerene (C 60 ) are frequently attracting scientific interest as a well-defined small-molecule model system for the study of internal interfaces between two organic semiconductors. They are prototypical representatives forming a donor-acceptor combination for studies of fundamental optoelectronic processes in organic photovoltaics. Despite thei

In this thesis, studies in the chemical synthesis of the dithiodiketopiperazine natural products (—)-glionitrin A and B are described.In Chapter 2, a synthesis of the indoline-fused 2,5-diketopiperazine core of glionitrin A and B using a C-H activation approach is described. The tricyclic core was prepared in only six steps and in a good overall yield (41%). In addition, the synthetic approach was

Pange lingua är en hymn från femhundratalet av Venantius Fortunatus. Den sjöngs under fastetiden och framför allt på långfredagen och återfinns i Den svenska psalmboken, men inte som en regelrätt översättning utan som bearbetningar och förkortningar, i psalmerna 147 och 456. Artikeln ger en bakgrund till hymnens tillkomst och en nyöversättning av hela hymnen.

Detta projekt har syftat till att ge svenska myndigheter och beslutsfattare enbeskrivning av samhällets problem efter ett kraftigt nedfall av långlivade radioaktivaämnen och hur den bästa kombinationen av åtgärder kan väljas för att skyddamänniskor mot bestrålning med hänsyn till ekonomiska, sociala och samhälleligafaktorer. Arbetet med att återställning av ett tätortsområde som berörts av enomfat

Analyzing temperature dependent photoemission (PE) data of the ferromagnetic Kondo-lattice (KL) system YbNiSn in the light of the periodic Anderson model (PAM) we show that the KL behavior is not limited to temperatures below a temperature TK, defined empirically from resistivity and specific heat measurements. As characteristic for weakly hybridized Ce and Yb systems, the PE spectra reveal a 4f-d

Radiological staging of rectal cancer dictates subsequent patienttreatment. In early-stage disease, local excision is associatedwith reduced morbidity, mortality, and costs, and maintainsbowel continuity compared with surgery, where the whole orpart of the rectum is resected1–3. Nearly 90 per cent of patientswith T1 rectal cancer have N0 disease and are therefore potentially curable with local res

Concerns have been raised over the quality of evidence on the performance of medical artificial intelligence devices, including devices that are already on the market in the USA and Europe. Recently, the Medical Device Regulation, which aims to set high standards of safety and quality, has become applicable in the European Union. The aim of this article is to discuss whether, and how, the Medical
