Semi-global Chemical Kinetic Mechanism for FAME Combustion Modeling

Modeling of combustion engines using computational fluid dynamics (CFD), to investigate and improve performance of biodiesel combustion, calls for development of small and efficient chemical kinetics mechanisms that accurately represent ignition and flame propagation of renewable fuels. In this work, a semi-global approach is used to develop a mechanism suitable for three-dimensional CFD of fatty

Search, save and share: family historians’ engagement practices with digital platforms

Alongside established heritage institutions, family historians are central figures in the ecosystem of digital heritage, both as contributors to and users of digitized historical sources. With that in mind, this research aims for a wide examination of family historians’ engagement with the broader selection of available digital platforms, providing knowledge about how and why they choose to use on

Solo mothers’ by choice experiences during pregnancy and early parenthood : Thoughts and feelings related to maternal health-services

The present study examined the thoughts and feelings of solo mothers by choice (SMC) regarding their experiences during pregnancy and early parenthood, with special focus on their contact with maternal health-services (MCHS). Semi-structured interviews were carried out with solo mothers (N = 10) who had undergone assisted fertilization in Sweden. Thematic analysis revealed two main themes. The fir

Incidental pulmonary embolism in patients with cancer : prevalence, underdiagnosis and evaluation of an AI algorithm for automatic detection of pulmonary embolism

Objectives: To assess the prevalence of reported and unreported incidental pulmonary embolism (iPE) in patients with cancer, and to evaluate an artificial intelligence (AI) algorithm for automatic detection of iPE. Methods: Retrospective cohort study on patients with cancer with an elective CT study including the chest between 2018-07-01 and 2019-06-30. All study reports and images were reviewed t

Shared language is essential : Communication in a multiethnic obstetric care setting

This study focuses on communication and conceptions of obstetric care to address the postulates that immigrant women experience sensitive care through the use of an ethnically congruent interpreter and that such women prefer to meet health providers of the same ethnic and gender profile when in a multiethnic obstetrics care setting. During 2005-2006, we conducted in-depth interviews in Greater Lon

Experimental Validation of Single Base Station 5G mm Wave Positioning : Initial Findings

5G cellular networks can utilize millimeter wave signals, and support large bandwidths and large antenna arrays, which provide more geometric-based signals and higher delay and angle resolutions. These merits bring new opportunities in positioning the user with limited infrastructure through the use of combined angle and delay information. However, there are many practical challenges to overcome,

Exhaled oral and nasal nitric oxide during L-arginine infusion in preeclampsia

OBJECTIVE: To determine the effects of the nitric oxide (NO) precursor L-arginine on the airway NO concentration in patients with preeclampsia.METHODS: NO was measured by a noninvasive chemiluminescence technique in air sampled directly from nasal and oral cavities during expiration before and during L-arginine infusion in 9 preeclamptic and 10 control pregnancies. Maternal blood pressure and hear

Designing Accessible Elections : Recommendations from Disability Voting Rights Advocates

Disability is frequently cited as a reason that Americans do not vote. This article offers legal and policy practitioner perspectives on core challenges people with disabilities face in exercising their voting rights in the United States, from obtaining election information to casting their ballots. Drawing on our collective experience-which includes professional experience as advocates working to

Environmentally induced DNA methylation is inherited across generations in an aquatic keystone species

Transgenerational inheritance of environmentally induced epigenetic marks can have significant impacts on eco-evolutionary dynamics, but the phenomenon remains controversial in ecological model systems. We used whole-genome bisulfite sequencing of individual water fleas (Daphnia magna) to assess whether environmentally induced DNA methylation is transgenerationally inherited. Genetically identical

Panopticon in the Urinal? : the Stockholm homo-sex Commission C. 1950–1965

This article examines the records of the so-called homo-sex commission—a part of the municipal Stockholm police force dedicated to the policing of male same-sex practices—as a case study of the role of policing in shaping historical understandings of homosexuality. Building on a series of documents left by the commission and high-ranking police officers, from memoranda describing the nature of hom

LRIG proteins regulate lipid metabolism via BMP signaling and affect the risk of type 2 diabetes

Leucine-rich repeats and immunoglobulin-like domains (LRIG) proteins have been implicated as regulators of growth factor signaling; however, the possible redundancy among mammalian LRIG1, LRIG2, and LRIG3 has hindered detailed elucidation of their physiological functions. Here, we show that Lrig-null mouse embryonic fibroblasts (MEFs) are deficient in adipogenesis and bone morphogenetic protein (B

Bioderived, chiral and stable 1-dimensional light-responsive nanostructures : Interconversion between tubules and twisted ribbons

HYPOTHESIS: Self-assembling molecular structures responding to light stimulus are appealing for applications as sensing and drug delivery. Supramolecular nanotubes have a relevant potential in nanotechnology as they can be used to encapsulate different loads like drugs, biological macromolecules, and nanomaterials. In addition, they are suitable elements for novel supracolloidal materials. Structu

Stability of Robotic Obstacle Avoidance and Force Interaction

Stability problems associated with robot control with obstacle avoidance are analysed. Obstacle avoidance algorithms based on potential function are revised to accomplish stable re-design. A stability proof using Lyapunov theory and passivity theory is provided for the re-designed obstacle avoidance algorithm. The paper presents a modification of potential functions for obstacle avoidance aiming t

Probabilistic analysis of climate change impact on chloride-induced deterioration of reinforced concrete considering Nordic climate

The impact of climate change on the deterioration of reinforced concrete elements have been frequently highlighted as worthy of investigation. This article addresses this important issue by presenting a time-variant reliability analysis to assess the effect of climate change on four limit states; the probabilities of corrosion initiation, crack initiation, severe cracking, and failure of a simply

Molecular advances to study the function, evolution and spectral tuning of arthropod visual opsins

Visual opsins of vertebrates and invertebrates diversified independently and converged to detect ultraviolet to long wavelengths (LW) of green or red light. In both groups, colour vision largely derives from opsin number, expression patterns and changes in amino acids interacting with the chromophore. Functional insights regarding invertebrate opsin evolution have lagged behind those for vertebrat

The Political Impact of the Sustainable Development Goals : Transforming Governance through Global Goals?

Written by an international team of over sixty experts and drawing on over three thousand scientific studies, this is the first comprehensive global assessment of the political impact of the Sustainable Development Goals, which were launched by the United Nations in 2015. It explores in detail the political steering effects of the Sustainable Development Goals on the UN system and the policies of

Analys av rörlig bild

Medan metoder för datadriven textanalys har utvecklats mycket under de senaste decennierna är det först nu som liknande metoder har börjat användas för att studera rörliga bilder. Detta kapitel utforskar möjligheterna med datorstödd analys av rörlig bild – såväl för att genomföra närläsningar som för mer storskaliga filmanalyser. Bland annat presenteras moderna annoteringsprogram, videoessäer och
