Optical diagnostics of misfire in partially premixed combustion under low load conditions

To clarify the misfire mechanism is important for stabilizing combustion in partially premixed combustion (PPC) under low load. Fuel-tracer planar laser-induced fluorescence (PLIF), formaldehyde PLIF, flame and OH* natural luminosity imaging were utilized to qualify the local equivalence ratio, low-temperature reaction and the high-temperature flame features in an optical engine. Results show that

Usability Study of the iACTwithPain Platform : An Online Acceptance and Commitment Therapy and Compassion-Based Intervention for Chronic Pain

Background: This pilot study aims to test the usability of the iACTwithPain platform, an online ACT-based intervention for people with chronic pain, to obtain information on which intervention and usability aspects need improvement and on expected retention rates. Methods: Seventy-three Portuguese women with chronic pain were invited to complete the first three sessions of the iACTwithPain interve

Internal Retrofitting with Hemp-Lime on Brick Masonry : a Study to Prevent Damage Caused by Sodium Sulphate

In Sweden there are a great number of neo-gothic churches built in brick masonryaround 1870-1910. They are constructed as massive masonry walls with façadebricks attached to a core of massive red bricks. In the majority of these churchesthere is a presence of sodium sulphate causing salt damages. The source of the salts is known to be the red masonry bricks and the damage occurs both internally an

Moisture Levels in Historic Timber Walls Insulated with Hemp-Lime

The European Union has a low-carbon roadmap that aims at reducing greenhouse gas emissions toprevent further climate change and achieve climate-neutrality by 2050. Many of the historical buildings that wehave today will still be around in 2050. Hence, there is a need to improve their energy performance. A way to dothis is to use hemp-lime as a material for renovation. Hemp shiv, the woody core par

Attacks on the Firekite Cipher

Firekite is a synchronous stream cipher using a pseudo-random number generator (PRNG) whose security is conjectured to rely on the hardness of the Learning Parity with Noise (LPN) problem. It is one of a few LPN-based symmetric encryption schemes, and it can be very efficiently implemented on a low-end SoC FPGA. The designers, Bogos, Korolija, Locher and Vaudenay, demonstrated appealing properties

Risk for Mould Growth on Hemp-Lime at Different Relative Humidity

Microbial growth often thrives in humid conditions, at high relative humidity. Moulds are complex organisms; many types of mould are able to survive strong variations in humidity and temperature, such as those on building façades. For some building materials a critical relative humidity is determined, which functions as a theoretical threshold; at this (or lower) relative humidity microbial growt

Plasma proteome profiling of healthy individuals across the life span in a Sicilian cohort with long-lived individuals

The study of healthy human aging is important for shedding light on the molecular mechanisms behind aging to promote well-being and to possibly predict and/or avoid the development of age-related disorders such as atherosclerosis and diabetes. Herein, we have employed an untargeted mass spectrometry-based approach to study age-related protein changes in a healthy Sicilian plasma cohort including l

Comparative Genomics of the Waterfowl Innate Immune System

Animal species differ considerably in their ability to fight off infections. Finding the genetic basis of these differences is not easy, as the immune response is comprised of a complex network of proteins that interact with one another to defend the body against infection. Here, we used population- and comparative genomics to study the evolutionary forces acting on the innate immune system in nat

Uptake of cervical cancer screening and its predictors among women of reproductive age in Gomma district, South West Ethiopia : a community-based cross-sectional study

Background: Cervical cancer is a public health challenge despite the available free screening service in Ethiopia. Early screening for cervical cancer significantly improves the chances of successful treatment of pre-cancers and cancers among women of reproductive age. Therefore, this study aimed to assess the uptake of screening and identify the factors among women of reproductive age. Methods: A

Futures of Fixing : Exploring the life of product users in circular economy repair society scenarios

A Circular Economy (CE) constitutes one pathway towards realising sustainable productionand consumption. Here, the repair of broken products (compared to replacement) consti-tutes an important strategy to keep products in the economy for longer, thereby reducingwaste, as well as the need to extract resources and emit pollution in the manufacture of areplacement product. In today’s world, repair do

Enrichment of Complement, Immunoglobulins, and Autoantibody Targets in the Proteome of Platelets from Patients with Systemic Lupus Erythematosus

Background Systemic lupus erythematosus (SLE) is a complex disease characterized by autoimmunity toward apoptotic cells, excessive amounts of circulating immune complexes, and complement activation. A decreased platelet size has been observed in SLE and their nonhemostatic functions may play an active role in the disease. The main objective of this study was to find clues that could explain their

The Organisation of Prayer Rooms in Educational Institutions in Denmark : Moderate Secularism Between Perception and Practice

In 2017, the Danish parliament discussed prayer rooms at educational institutions in a broadly publicised controversy. The debate followed a series of issues arising from such institutions’ changing demography, resulting in increased Muslim presence. Beneath the public and parliamentary debate in 2017, civil servants in ministries and educational institutions became highly engaged in negotiating w

Inflammatory cytokines and mechanical injury induce post-traumatic osteoarthritis-like changes in a human cartilage-bone-synovium microphysiological system

Background: Traumatic knee injuries in humans trigger an immediate increase in synovial fluid levels of inflammatory cytokines that accompany impact damage to joint tissues. We developed a human in vitro cartilage-bone-synovium (CBS) coculture model to study the role of mechanical injury and inflammation in the initiation of post-traumatic osteoarthritis (PTOA)-like disease. Methods: Osteochondral

Hampakalk : Tilläggsisolering på reveterade trähus och saltskadat tegelmurverk - Slutrapport

Historiska byggnaders energiprestanda behöver hållbart förbättras samtidigt som kulturhistoriska värden bevaras. Ett byggnadsmaterial som hampakalk skulle kunna uppfylla en ny funktion i renovering av historiska byggnader. Syftet var att finna en effektiv och resurssnål metod för tilläggsisolering av reveterade och putsade historiska trä- och tegelhus som är kompatibel med stommen, ökar energieffe

Prediction of Ki-67 expression of breast cancer with a multiparametric model using MRI parameters from ultrafast DCE-MRI and DWI

The purpose of this study is to investigate the prediction of Ki-67 expression of breast cancers using MRI parameters from ultrafast (UF) DCE-MRI, DWI, T2WI, and the lesion size. Breast MRI was performed with a 3T scanner using dedicated breast coils. UF DCE-MRI was obtained using Compressed Sensing-VIBE (prototype sequence). As a kinetic parameter of UF DCE-MRI, maximum slope (MS) was defined as

Following the Kinetics of Undercover Catalysis with APXPS and the Role of Hydrogen as an Intercalation Promoter

While improved catalytic properties of many surfaces covered by two-dimensional materials have been demonstrated, a detailed in situ picture of gas delivery, undercover reaction, and product removal from the confined space is lacking. Here, we demonstrate how a combination of gas pulses with varying compositions and time-resolved ambient pressure photoelectron spectroscopy can be used to obtain su
