The number of underground metro stations around the world is steadily increasing and deep stations are becoming more common. Evacuation elevators can be a way to mitigate many of the evacuation problems of deep stations, e.g., fatigue. However, the elevators need to be used by evacuees to be effective. In order to study the influence of evacuation measures on elevator usage, experiments were perfo

In recent years, parenting support has gained traction in the Swedish welfare state in both policy and practice. Parenting is seen as determining child outcomes and are thus in need of knowledge and expertise. Yet, at the same time, parents are conceptualised as experts of their own child. The intriguing paradox between parents being experts while at the same time being in need of parenting suppor

Purpose: Hunter Harrison, CEO of the railroad company CSX, died on December 16, 2017. Harrison, known as the railroad transformation guru, was a controversial person. While his transformations were applauded by investors, they were also subject to significant criticism. The author changes triggered service disruptions, customer complaints and federal scrutiny. The purpose of this paper is to condu

A combination treatment (CT) of proinsulin and IL-10 orally delivered via genetically modified Lactococcus lactis bacteria combined with low-dose anti-CD3 (aCD3) therapy successfully restores glucose homeostasis in newly diagnosed non-obese diabetic (NOD) mice. Tolerance is accompanied by the accumulation of Foxp3+ regulatory T cells (Tregs) in the pancreas. To test the potential of this therapy o

The transcriptional response of hosts to genetically similar pathogens can vary substantially, with important implications for disease severity and host fitness. A low pathogen load can theoretically elicit both high and low host responses, as the outcome depends on both the effectiveness of the host at suppressing the pathogen and the ability of the pathogen to evade the immune system. Here, we i

Purpose: Trapped fourth ventricle (TFV) is a well-identified problem in hydrocephalic children. Patients with post-hemorrhagic hydrocephalus (PHH) are mostly affected. We tried to find out predisposing factors and describe clinical findings to early diagnose TFV and manage it. Methods: We reviewed our database from 1991 to 2018 and included all patients with TFV who required surgery. We analyzed p

Många växt- och djurarter har missgynnats av landskapsförändringar och riskerar att försvinna om de inte får hjälp. Länsstyrelsen upprättade därför 2017 en lista med förslag på kommunala ansvarsarter i Skåne. Varje kommun har tilldelats några hotade arter som har sin utbredningsmässiga tyngdpunkt i kommunen.

Aims: Although nitrogen (N) fixation by moss-associated bacteria is the main source of new N in N-limited ecosystems like arctic tundra, we do not know which nutrient, molybdenum (Mo) or phosphorus (P), is rate-limiting for sustaining this process in the long-term. Further, how moss-associated N2 fixation impacts the belowground microbial regulation of decomposition remains unresolved. Methods: Mo

The paper takes up a well-known constitutional subject concerning the limitations of private bills by reformulating the problem in system theoretical terms. This move allows for examining how the law as a social system carries through the task of establishing distinctions between legal/illegal in a situation where there is no precedence in the form of prior court decisions. After a short introduct

Purpose: To study the test–retest reliability of the Catquest-9SF questionnaire in cataract surgery. Methods: A single-centre prospective non-randomized test–retest study was conducted using the Swedish National Cataract Register and the Catquest-9SF questionnaire, which is a valid patient-reported outcome measurement tool developed and used for evaluating quality and visual disability outcome in

We study the systematics and evolutionary history of the Afrotropical butterfly genus Mylothris (Lepidoptera: Pieridae) based on six gene regions (COI, EF1a, GAPDH, MDH, RpS5 and wingless). We find that the genus can be placed into five species groups, termed the jacksoni, elodina, rhodope, agathina and hilara groups. Within these species groups, we find that many species show very little genetic

Potent chemotherapeutic agents are required to counteract the aggressive behavior of cancer cells and patients often experience severe side effects, due to tissue toxicity. Our study addresses if a better balance between efficacy and toxicity can be attained using the tumoricidal complex alpha1-oleate, formed by a synthetic, alpha-helical peptide comprising the N-terminal 39 amino acids of alpha-l

Background & Aims: The I148M variant in PNPLA3 is the major genetic risk factor for non-alcoholic fatty liver disease (NAFLD). The liver is enriched with polyunsaturated triglycerides (PUFA-TGs) in PNPLA3-I148M carriers. Gene expression data indicate that PNPLA3 is liver-specific in humans, but whether it functions in adipose tissue (AT) is unknown. We investigated whether PNPLA3-I148M modifie

Plant carbon (C) partitioning—the relative use of photosynthates for biomass production, respiration, and other plant functions—is a key but poorly understood ecosystem process. In an experiment with Zea mays, with or without arbuscular mycorrhizal fungi (AMF), we investigated the effect of phosphorus (P) fertilization and AMF on plant C partitioning. Based on earlier studies, we expected C partit

Aims: Hepatitis C virus (HCV) is a slowly progressive disease, often transmitted among people who inject drugs (PWID). Mortality in PWID is high, with an overrepresentation of drug-related causes. This study investigated the risk of death in patients with chronic hepatitis C virus (HCV) infection with or without illicit substance use disorder (ISUD). Methods: Patients with HCV were identified usin

We present a software package, Modes, offering h-adaptive and p-adaptive linear multistep methods for first order initial value problems in ordinary differential equations. The implementation is based on a new parametric, grid-independent representation of multistep methods [Arévalo and Söderlind 2017]. Parameters are supplied for over 60 methods. For nonstiff problems, all maximal order methods (

In 2011, a monument commemorating a group of Polish academics killed during the Nazi occupation was unveiled at the site of their death in Lviv, presently a Ukrainian city. This event became the pinnacle of a commemoration that had developed quite autonomously on both sides of the redrawn Polish-(Soviet)Ukrainian border. The commemorative project and memory event underpinning it are especially int
