Double-chain amphiphilic compounds, including surfactants and lipids, have broad significance in applications like personal care and biology. A study on the phase structures and their transitions focusing on dioctadecyldimethylammonium chloride (DODAC), used inter alia in hair conditioners, is presented. The phase behaviour is dominated by two bilayer lamellar phases, Lβ and Lα, with “solid” and “

The Pleistocene-Holocene transition brought turbulent times to human societies confronted by rapid climatic fluctuations, shifts inbiogeographic zones and the flooding of continental shelves. While the disappearance of Doggerland’s inhabited landscapes underthe grey waters of the North Sea marks the culmination of these changes for European Archaeologists, our aim is this paper is todraw parallels

Knowledge of how to design digital systems that are ergonomically sound, high in usability, and optimized for the user, context, and task has existed for some time. Despite this, there are still too many examples of new digital health care systems that are poorly designed and that could negatively affect both the work environment of health care staff and patient safety. This could be because of a

Introduction: The aim of the study is to compare the effect of cervical length measured with transvaginal ultrasound in the second trimester on the risk of spontaneous preterm delivery (PTD) between different risk groups of asymptomatic women with a singleton pregnancy. Material and methods: This is a pre-planned exploratory analysis of the CERVIX study, a prospective blinded multicenter diagnosti

Non-invasive quantification of pressure-volume (PV) loops from brachial pressure and cardiovascular magnetic resonance is a validated method but its application has been limited to resting heart rates. The aim of this study was to improve the previous method and validate it against invasive left-ventricular pressure measurements in an experimental porcine model, and further apply it to 16 healthy

Shipping is associated with various environmental impacts, such as pollutants discharged to air and sea. Much of this pollution appears to be unregulated, and global emissions from shipping are expected to more than triple between 2020 and 2050. This paper reviews global, national, regional and port-level legislative approaches that have been implemented to reduce emissions of carbon dioxide (CO2)

Despite the long tradition of fieldwork and qualitative research practice in tourism studies, the reporting of methodological notes and reflections is limited in the literature. Many excellent methodological remarks in research reports and graduate theses find few outlets in academic journals and those few contributions that are eventually published often emphasize the novelty of the method rather

Abstract in Chinese本文通过分析 2016年在香港大学举办的“情欲中国：性与女性主体”展映纪录片，以及受邀但因伦理问题未参展的影片，探讨中国独立纪录片电影在处理隐私、性别、暴力、创伤等议题时的女权主义立场性：1）电影人的关怀伦理立场，以及与影片主人公形成（亲密）团结立场；2）影片主人公从坦白和渴求的立场出发，从基于性别的暴力和歧视中重宣自主；3）电影人与影片主人公从不同的立场出发，通过发行控制来降低纪录片对主人公个人生活可能造成的负面影响；4）片中人物与电影人自我转变的演进，因此恢复一度禁止的放映；5）从活跃分子立场出发的政治代言，以及从电影人立场出发的艺术意义上的再现；6）理论与实践之间的紧张关系要求学者、电影人和活跃分子反思性别与知识生产的传统关系，置身于具体处境中进行讨论和落实纪录片伦理。本文认为在制作、展映、评论中国关于女性的纪录片时，有必要采取女权主义的关怀伦理This article analyses a series of ‘Desiring China: Sexuality and Female Subjectivity’ screening and discussion of Chinese independent documentary films at the University of Hong Kong in 2016. It explores a feminist positionality in Chinese independent documentary film to deal with privacy, gender, violence, and trauma: 1) filmmaker’s position on the ethics of care and (intimate) solidarity with pr

This paper explores the activities of Swedish state supported ethnic associations (most of which are immigrant organizations), thus shedding empirical light on how immigrants organize with the help of state support, both nationally and transnationally, in a welfare state context. The paper is based on a study of annual reports of 52 state supported national associations, representing more than a t

PURPOSE To estimate age-specific relative and absolute cancer risks of breast cancer and to estimate risks of ovarian, pancreatic, male breast, prostate, and colorectal cancers associated with germline PALB2 pathogenic variants (PVs) because these risks have not been extensively characterized. METHODS We analyzed data from 524 families with PALB2 PVs from 21 countries. Complex segregation analysis

Introduction: We studied usefulness of combining blood amyloid beta (Aβ)42/Aβ40, phosphorylated tau (p-tau)217, and neurofilament light (NfL) to detect abnormal brain Aβ deposition in different stages of early Alzheimer's disease (AD). Methods: Plasma biomarkers were measured using mass spectrometry (Aβ42/Aβ40) and immunoassays (p-tau217 and NfL) in cognitively unimpaired individuals (CU, N = 591)

Carrion is a frequent but overlooked source of nutrients to the soil. The decomposition of carrion is accelerated by invertebrate scavengers, but the impact of the scavengers on below-ground biota and its functions is scarcely known. We conducted a laboratory experiment to investigate the effects of the burying beetle Nicrophorus vespilloides on the soil community of a temperate broadleaved forest

INTRODUCTION: Programmed death-ligand 1 (PD-L1) expression is used for treatment prediction in non-small cell lung cancer (NSCLC). While cytology may be the only available material in the routine clinical setting, testing in clinical trials has mainly been based on biopsies.METHODS: We included 2 retrospective cohorts of paired, concurrently sampled, cytological specimens and biopsies. Also, the l

Background and purpose — Cup wear in total hip arthroplasty (THA) can be affected by different manufacturing processes of the polyethylene (PE). We report the long-term wear pattern differences, as well as early creep behavior, between conventional PE and highly cross-linked PE (HXLPE) liners, as measured with radiostereometry (RSA) up to 10 years. We also compare migration and clinical outcome of

We define by interpolation a scale analogous to the Hardy Hp scale for complete Pick spaces, and establish some of the basic properties of the resulting spaces, which we call Hp. In particular, we obtain an Hp-Hq duality and establish sharp pointwise estimates for functions in Hp

Large-scale human exome sequencing can identify rare protein-coding variants with a large impact on complex traits such as body adiposity. We sequenced the exomes of 645,626 individuals from the United Kingdom, the United States, and Mexico and estimated associations of rare coding variants with body mass index (BMI). We identified 16 genes with an exome-wide significant association with BMI, incl

AbstractModern radiotherapy aims to treat the decease while minimizing the radiation dose to the adjacent normal tissue, to minimize acute and late effects of the treatment. The foremost technological approaches have been intensity modulated radiotherapy (IMRT) and intensity modulated proton therapy (IMPT) in combination with image guided radiotherapy (IGRT).
