The Swedish steel industry stands before a potential transition to drastically lower its CO2 emissions using direct hydrogen reduction instead of continuing with coke-based blast furnaces. Previous studies have identified hydrogen direct reduction as a promising option. We build upon earlier efforts by performing a technological innovation system study to systematically examine the barriers to a t

Background: Aneurysmal subarachnoid haemorrhage (SAH) is a variant of haemorrhagic stroke with a striking 50% mortality rate. In addition to the initial insult, secondary delayed brain injury may occur days after the initial ischemic insult and is associated with vasospasms leading to delayed cerebral ischemia. We have previously shown that the MEK1/2 inhibitor U0126 improves neurological assessme

The minimum edge dominating set (MEDS) is one of the fundamental covering problems in graph theory, which finds many practical applications in diverse domains. In this paper, we propose a meta-heuristic approach based on genetic algorithm and local search to solve the MEDS problem. Therefore, the proposed method is considered as a memetic search algorithm which is called Memetic Algorithm for mini

Teorin för optimala valutaområden är den grundläggande ramen för nationalekonomernas analys av för- och nackdelar med ett medlemskap i en valutaunion. I forskningen kring EMU intar den en central plats. Denna teori används här för att kartlägga detlämpliga eller ’’optimala’’ valutaområdet för Sverige. Granskningen visar att detta geografiska område i första hand bör omfattaFinland, möjligen också

Cell replacement is currently being explored as a therapeutic approach for neurodegenerative disease. Using stem cells as a source, transplantable progenitors can now be generated under conditions compliant with clinical application in patients. In this study, we elucidate factors controlling target-appropriate innervation and circuitry integration of human embryonic stem cell (hESC)-derived graft

Purpose: The purpose of this paper is to develop, implement, test and further enhance a framework for measuring organizational change initiatives. Design/methodology/approach: The conceptual part of the framework is based on the structured analysis of existing literature. The framework was further developed during an action research (AR) study where the authors developed, implemented, evaluated an

The article discusses the difficulties that faces children in Hadhramout -Yemen during the civil war. While the politicians and the other elites concentrate to fight terrorism and armed groups they ignore the needs of children, woman, and other marginalized groups.

Traditionally, research on human language has taken speech and written language as the only domains of investigation. However, there is now a wealth of empirical studies documenting visual aspects of language, ranging from rich studies of sign languages, which are self-contained visual language systems, to the field of gesture studies, which examines speech-associated gestures, facial expressions,

Heat transfer characteristics of an electric heater were experimentally investigated by using various fluids in this paper, including Cu-EGW (a mixture of ethylene glycol and DI-water), Al2O3-EGW, Fe3O4-EGW nanofluids. A 4:6 mixture of ethylene glycol and deionized water was used as the base liquid. All these nanofluids were prepared by ultrasonic treatment, and nanoparticle mass concentration of

Background: Although schools are a key setting for the provision of mental health support for young people, little is known about the facilitators and barriers for providing such support. This study aimed to collect information from schools in 10 European countries regarding the priority given to mental health support for students, existence of a mental health‐related school policy, links with rel

Modulated nanoparticle-coating surfaces were fabricated by an improved electrophoretic deposition technique in this study. Pool boiling experiments were studied for HFE-7200 on the modulated nanoparticle-coating surfaces, with a smooth surface and uniform coating surfaces as comparison. It was found that the present modulated coating surfaces can enhance the heat transfer coefficient and the criti

Friendship is an undertheorized but increasingly important relationship in late modernity. In this article, the authors present findings from two ongoing research projects about friendship, gender and age in contemporary Sweden. They argue that discourses about gender and friendship are highly relevant for how friendship is conceptualized both among men and women, but that culturally ingrained con
