The addition of Cr is known to work as an effective prevention against oxidation in Fe-based alloys. This can be attributed to the peripheral oxide, the structure of which is dependent on the composition of the alloy. Using Molecular Dynamic (MD) calculations with a Reactive Force Field (ReaxFF) potential, we successfully identify several oxide structures arising during initial oxide formation in The addition of Cr is known to work as an effective prevention against oxidation in Fe-based alloys.

The steel industry is with its high emissions an important sector to transform from fossil-fueled to fossil-free. In recent years, the technology development has accelerated quickly regarding iron ore reduction using hydrogen produced from electrolysis within the EL-DRP-EAF steel production route. However, it is problematic that the energy supply for the majority of the efforts made within the gre

The relationships between structure and function in human knee femoral cartilage are not well-known at different stages of osteoarthritis. Thus, our aim was to characterize the depth-dependent composition and structure (proteoglycan content, collagen network organization and collagen content) of normal and osteoarthritic human femoral condyle cartilage (n = 47) and relate them to their viscoelasti

Pointing with the chin is a practice attested worldwide: it is an effective and highly recognizable device for re-orienting the attention of the addressee. For the chin point to be observed, the addressee must attend carefully to the movements of the sender’s head. This demand comes into conflict with the politeness norms of many cultures, since these often require conversationalists to avoid meet

Transcending initial efforts to make cities “climate smart” by focusing on the potential of new technologies and infrastructural interventions, various actors are increasingly interested in deploying nature to help achieve urban resilience. In this context, rather than taking resilience as a given property of particular systems or entities, it is important to examine why, how, with what implicatio

It has been argued that older people living with dementia often experience stigma. Several media interventions have been designed to raise public awareness about dementia, as well as to de-stigmatise the condition and people living with it; however, few studies have investigated how media interventions may serve to reduce stigma. The present study focused on a Chinese reality show, Forget Me Not C

Obstetric records of hospital births of children present in the Scanian Economic Demographic Database. The records contain information on gestational age, birthweight, and other indicators of health of the child, as well as information on maternal health.

Trots att jordbrukets näringsutsläpp till Östersjön har minskat krävs mycket mer för att uppnå de uppsatta miljömålen. Vi har utvärderat politiken som används för att minska utsläppen från de nio länder som samarbetar om restaureringen av Östersjön. Vi finner att den nuvarande politiken är otillräcklig eftersom:Många länder har inte genomfört de utlovade åtgärderna för att minska näringsutsläpp fr

This paper presents a joint numerical and experimental study of the ignition process and flame structures in a gasoline partially premixed combustion (PPC) engine. The numerical simulation is based on a five-dimension Flamelet-Generated Manifold (5D-FGM) tabulation approach and large eddy simulation (LES). The spray and combustion process in an optical PPC engine fueled with a primary reference fu

Background: Little is known about how PFAS concentrations in human milk change over the course of lactation, although this is an important determinant of cumulative infant exposure from breastfeeding.Objective: To estimate changes in PFAS concentrations in human milk over the course of lactation in a population with a wide range of exposure from background-to high-exposed.Methods: We measured PFAS

Optimising reactions in artificial photosynthesis research requires screening of many reaction and operation parameters, which is often resource-intense and time-consuming. In this paper, we demonstrate the use of a rotational Raman-based spectrometer for non-invasive quantification of several gases (H2, O2, N2, CO, CO2) with short analysis times (15 s), enabling high throughput screening. Further

In this article we discuss how two types of popular romances – the desert romance and the governess romance – have blended into what we refer to as the desert-governess romance. In the world of romance, the governess and the sheikh may be an odd couple but they do make good bedfellows. Etymologically speaking, the governess (“A woman who holds or exercises authority” (OED)) is the perfect love matIn this article we discuss how two types of popular romances – the desert romance and the governess romance – have blended into what we refer to as the desert-governess romance.

Providing an in-depth and cutting-edge investigation into the rise of Asian research practices and paradigms, Mats Benner examines how this rise has been accomplished, what effects it has had, and how it has shaped universities across seven Asian countries.

This article presents the first measurement of the interaction between charm hadrons and nucleons. The two-particle momentum correlations of pD- and p¯D+ pairs are measured by the ALICE Collaboration in high-multiplicity pp collisions at s=13 TeV. The data are compatible with the Coulomb-only interaction hypothesis within (1.1-1.5)σ. The level of agreement slightly improves if an attractive nucleo

Purpose: A preoperative estimate of the risk of malignancy for intraductal papillary mucinous neoplasms (IPMN) is important. The present study carries out an external validation of the Shin score in a European multicenter cohort. Methods: An observational multicenter European study from 2010 to 2015. All consecutive patients undergoing surgery for IPMN at 35 hospitals with histological-confirmed I

Artikeln undersöker temporal styrning i den svenska asylbyråkratin genom en kvalitativ analys av tio familjers asylakter. Dessa består av över 5 000 sidors dokumentation: asylutredningsprotokoll, beslut, domar, intyg, överklaganden, inlagor, personliga brev, minnesnoteringar med mera. Studien fokuserar särskilt på Migrationsverkets beslut och de muntliga utredningar som myndighetens handläggare ha
