The building blocks of Titan and Enceladus are believed to have formed in a late-stage circumplanetary disk (CPD) around Saturn. Evaluating the evolution of the abundances of volatile species in this disk as a function of the migration, growth, and evaporation of icy grains is then of primary importance to assess the origin of the material that eventually formed these two moons. Here we use a simp
As physical distancing is a core measure of containing the spread of COVID-19, this pandemic is a crisis that has uprooted social interaction. While current research mainly focuses on crises as a challenge for entrepreneurial ventures and potential regulatory response mechanisms, we complement this research by addressing the question of how crises in general—and COVID-19's physical distancing meas
This article discusses a key methodological difficulty in conducting qualitative research close to home: the issue of overthinking. Whereas MALINOWSKI's concern regarding imponderabilia, i.e., the risk of not thinking about the subtle phenomena of everyday life, has long haunted ethnographers and qualitative researchers, not least those working "at home," we highlight an issue of overponderabilia,
Using 10 polymorphic microsatellites and 1251 individual samples (some dating back to the early 1980s), genetic structure and effective population size in all native and introduced Swedish populations of the European wels catfish or Silurus glanis were studied. Levels of genetic variability and phylogeographic relationships were compared with data from a previous study of populations in other part
Earth system models (ESMs) are key tools for providing climate projections under different scenarios of human-induced forcing. ESMs include a large number of additional processes and feedbacks such as biogeochemical cycles that traditional physical climate models do not consider. Yet, some processes such as cloud dynamics and ecosystem functional response still have fairly high uncertainties. In t
Low carbon input due to increasing specialization, intensification and reduced use of bio-fertilizer, leads to soil organic carbon (SOC) decreases in arable land. This is an emerging problem in Europe in general, where 45% of the EU soils have low and declining SOC content. SOC losses from agricultural soils influence soil fertility, putting food security at risk, and contributes to greenhouse gas
We consider channel estimation (CE) in narrowband Internet-of-Things (NB-IoT) systems. Due to the fluctuations in phase within receiver and transmitter oscillators, and also the residual frequency offset (FO) caused by discontinuous receiving of repetition coded transmit data-blocks, random phase noises are presented in received signals. Although the coherent-time of fading channel can be assumed
In adaptive immune receptor repertoire analysis, determining the germline variable (V) allele associated with each T- and B-cell receptor sequence is a crucial step. This process is highly impacted by allele annotations. Aligning sequences, assigning them to specific germline alleles, and inferring individual genotypes are challenging when the repertoire is highly mutated, or sequence reads do not
In September 2019, streets across the world filled with millions of children and youth demanding climate action, demonstrating the growing concern young people feel about their futures (Taylor, Watts, & Bartlett, 2019). However, protests are only one of the methods youths use to show their dissatisfaction with current climate change policies. Youth are also utilizing education, entrepreneurshi
Objective: To objectively assess anorectal dysfunction following nerve-sparing radical hysterectomy in stage I-II cervical carcinoma patients. Material and Methods: Between 2008 and 2012, 21 patients with primary cervical cancer stage FIGO I-II were enrolled in this prospective study. All women underwent nerve-sparing radical hysterectomy. Anorectal manometry was performed preoperatively and 6 mon
The effect of thermal ionization on the growth of soot particles has been analyzed by detailed kinetic modeling of a low-pressure premixed acetylene flame. The detailed kinetic model considers the oxidation of fuel, the formation and growth of polycyclic aromatic hydrocarbons, and particle inception, coagulation, as well as mass growth via surface reactions. A numerical method has been developed,
Aggrecan, versican, neurocan, and brevican are important components of the extracellular matrix in various tissues. Their amino-terminal globular domains bind to hyaluronan, but the function of their carboxyl-terminal globular domains has long remained elusive. A picture is now emerging where the C-type lectin motif of this domain mediates binding to other extracellular matrix proteins. We here de
Popular Abstract in Swedish Cancer är den ledande dödsorsaken i världen och stod för 7,6 miljoner dödsfall under 2008, vilket beräknas vara omkring 13 % av den totala dödsfallsiffran. Även om det finns flera olika metoder för att behandla eller bromsa cancerutveckling, krävs det nya terapier på grund av allvarliga biverkningar och otillfredsställande resultat med de nuvarande behandlingsmetoderna.Proteoglycans (PG) are highly anionic macromolecules consisting of a core protein covalently substituted with long unbranched polysaccharide chains called glycosaminoglycans (GAGs). PGs are central components in multicellular organisms, and they may occur in the extracellular matrix (ECM), at the cell surface, or in the secretory pathway. At the tumor cell surface, PGs and GAGs are involved in the
End-to-side (ETS) nerve repair is used in selected clinical cases. The mechanisms, by which regeneration into the attached nerve segment is initiated and occur, are still not fully understood. Based on numerous experimental studies, different mechanisms have been Suggested by which regenerating axons are recruited, such as contamination From the proximal nerve segment, collateral sprouting, and te
Dampness in indoor environments may cause various health problems. The specific causative agent(s) are unknown but may originate from degradation processes in damp materials, microbial growth, or a combination of these phenomena. The health impact of dampness in buildings is a politically, legally, and economically important question. Scientists at the U.S. EPA and Lawrence Berkeley National Labor
In some European countries, landscape analysis has long been used in support of large-scale planning or major projects such as new trunk roads and mainline rail routes, in line with both the UN's Convention on Environmental Impact Assessment and the European Landscape Convention. Some countries, however, lack a regulatory framework for what should be analysed, how a landscape analysis should be co
Subject-verb agreement in number (3sg - 3pl) in spoken French is a heterogeneous morpho-syntactic domain where number is expressed in some groups of verbs and in some phonological contexts only. The acquisition of this agreement is a long and gradual process (Prévost, 2009). Both children learning French as their first language (L1) and older second language (L2) learners overuse the dominant patt
Arabidopsis thaliana has two isoforms of alpha-glycan phosphorylase (EC 2.4.1.1), one residing in the plastid and the other in the cytosol. The cytosolic phosphorylase, PHS2, acts on soluble heteroglycans that constitute a part of the carbohydrate pool in a plant. This study aimed to define a physiological role for PHS2. Under standard growth conditions phs2 knock-out mutants do not show any clear
