The erection process of in situ cast concrete frameworks in multi-storey housing consists of multiple on site activities in which labour, equipment and materials are interacting in a complex system. Studies have shown that the current process involves a wide range of non-value adding activities, resulting in poor process efficiency. This paper presents a model developed for discrete-event simulati
This article examines the novel and film, Balzac et la petite tailleuse chinoise, by the Franco-Chinese writer and filmmaker Dai Sijie, the story of which takes place against the background of the Cultural Revolution. The first part of my analysis will make clear how the film illuminates and dramatizes the special texture, aesthetic, and structure of the novel. I then move on to investigate the li
This paper presents a new control strategy for an underactuated two-link robot, called the Pendubot. The goal is to create stable oscillations of the outer link of the pendubot, which is not directly actuated. We exploit a recently proposed feedback control design strategy, based on motion planning via virtual holonomic constraints. This strategy is shown to be useful for design of regulators for
Mental health problems among children and youth is positioned as one of the most urgent public health issues in Sweden today. Both research and official reports assert that mental health issues have increased among adolescents, especially girls, during the last decades. The aim of this study is to investigate how changes in childhood and gender discourses has implicated the construction of young p

Despite improvements, lung transplantation remains hampered by both a scarcity of donor organs and by mortality following primary graft dysfunction (PGD). Since acute respiratory distress syndrome (ARDS) limits donor lungs utilization, we investigated cytokine adsorption as a means of treating ARDS donor lungs. We induced mild to moderate ARDS using lipopolysaccharide in 16 donor pigs. Lungs were
The Swedish National Library published together with the university libraries in Gothenburg, Lund, Stockholm, Umeå and Uppsala in January 2020 a Declaration of Intent where the goal to digitiz Swedish print from the 15th century until today was formulated. Based on this objective, the article discusses different digitization strategies in libraries. Mass digitization stands for the rapid digitizat
Prior research has shown that companies in various industrial contexts need to achieve both exploitation of current knowledge and technologies to make profits today, and exploration of new knowledge and technologies to adapt to changing conditions and prepare for tomorrow’s demands. The capacity to achieve both exploration and exploitation is especially problematic in project based organizations d
In 1798 the Royal Academy of Science instituted a classification of its members, designating the last class to be filled by those engaged with world of learning and beautiful arts. This study maps the population of this “erudite class” and analyzes the negotiation of epistemic virtues and merits linked to the nebulous field from which the class drew its members. The article argues that a previous
Ov Cristian Norocels artikel diskuterar den svenska högerradikala populismenutifrån ett feministiskt perspektiv. Han kartlägger Sverigedemokraternas omtolkningar av den nationella metaforen om ”det svenska folkhemmet” och analyserar konstruktionen av maskuliniteter inom svensk högerradikal populism. Norocel för fram en specifik tolkning av den begreppsliga metaforteorin, en tolkning som innefattar
For patients living with chronic conditions, the daily life will change due to symptoms, drug treatment, and psychosocial factors caused by the disease. Our studies show that Swedish patients with PAH or CTEPH are satisfied with the information they have received, but still have a wish for more. Therefore, it is important to repeat the information on a regular basis and to make sure that patients
Purpose: The purpose of this paper is to enhance the heat transfer and thermal performance in the trailing edge region of the vane with vortex generators (VGs). Design/methodology/approach: This numerical study presents the enhancement of thermal performance in the trailing part of a gas turbine blade. In the trailing part, generally, pin fins are used either in staggered or in-line arrangements t
Forskare vid Lunds universitet har upptäckt ett cellskelett som ger struktur åt mito-kondrierna, cellens energifabriker. Skelettet är nödvändigt för mitokondriernas funktion, men forskarna fann även att cancerceller trots defekter utnyttjar skelettet för att kunna bibehålla sin energiproduktion – och därigenom överleva. Cellskelettet i mitokondrierna fungerar ungefär som ett armeringsnät och hjälp
Cholesterol-rich clusters of SNARE (soluble NSF attachment protein receptor) proteins have been implicated as being important for exocytosis. Here we demonstrate the significance of cholesterol for normal biphasic insulin secretion in mouse beta cells by removal of cholesterol from the plasma membrane using methyl-beta-cyclodextrin (MBCD). Maximal inhibition of insulin secretion in static incubati
Inflammation influences several steps of adult neurogenesis, but whether it regulates the functional integration of the new neurons is unknown. Here, we explored, using confocal microscopy and whole-cell patch-clamp recordings, whether a chronic inflammatory environment affects the morphological and electrophysiological properties of new dentate gyrus granule cells, labeled with a retroviral vecto
