There are several solutions to keep the workers at good thermal state at hot or cold workplaces, for example, PCM (phase change materials) and ice; electrically heated clothing; increase/decrease clothing insulation, e.g. with smart textiles; water based cooling/heating; air based systems, ventilated clothes. Following methods can be used to increase the ventilation in the clothes: use of air perm
Starting out from the rather different views on Ego and Alter formulated by Peirce and Bakhtin, and, more indirectly, by Foucault, the present contribution attempts to characterise the position of these familiar philosophical personages within the framework of cultural semiotics, as it has been adapted in Lund from the models of the Prague and Tartu schools. The resulting model is tried out in a c
Injectable bone substitutes (IBS) based on calcium phosphate (CaP) and/or calcium sulphate (CaS) are used as fillers in bone defects to stimulate bone integration and allow mechanical loading. Two types of IBS, IBS-1 is CaP+20%CaS and IBS-2 is CaS+40% hydroxyapatite, were investigated. The materials were injected into holes in the femur and tibia in rabbits. After 10 weeks the femora were subjecte
Wear in forming tools and contact problems between sheet-metal and tool-material are common problems in manufacturing industries and sheet-metal-parts production. In this paper recent tool material experiences are presented. Quantitative determination of wear has been performed using micro hardness indentions made on the tool surface prior to pressings and thereafter measured. Wear tests are perfo
With a method relying on measurements of water vapour flow from a specimen and on measurements of distribution of relative humidity in the specimen at steady state conditions, it is possible to calculate the moisture permeability. Its dependence on relative humidity is presented.
Growing number of ISO 14001 certifications worldwide creates new possibilities for organizations to benefits from the global recognition of the standard. One of them is unequivocally the use of ISO14001 certificate as one of conditions for supply chain cooperation. Such situation pulls many enterprises into implementation of the systems for the bare reason of fulfilling the requirement, abreast to
Omdöme ”Teckenspråkiga döva” är en rik avhandling. Den innehåller spännande och djuplodande empiriskt material. Fredäng täcker samtidigt in ett stort fält från individnivå med familj och skola till lokalföreningar och riksorganisation och till hur samhället ställer sig i olika frågor. Det är sannolikt att de sociala typer som Päivi Fredäng tar upp, om hur döva ser på sig själva och sin dövhet l
Under början av förra seklet skedde en formlig reception av tysk processrätt genom Ernst Kallenbergs verk Svensk Civilprocessrätt i två band. Således kom läran om processföremålet genom 1942 års processreform att läggas till grund för utformningen av den svenska rättegångsbalken (RB). Läran om processföremålet innebär att saken är den omtvistade rättigheten i det bakom-liggande rättsförhållande soAt the turn of the last century, a formal reception of German procedural law took place through Ernst Kallenberg’s work ’Svensk Civilprocessrätt’ in two volumes. Thereby, the German doctrine on the essence of the claim formed the basis for the Swedish Code of Procedure, rättegångsbalken (RB), through the procedural reform of 1942. The doctrine on the essence of the claim holds that the matter cont
Many factors influence the language environment in preschool, for example, the language background and competence of the teachers, children's ages, language proficiency levels and language backgrounds, the access to play and learning materials and the composition of preschool groups. There is a lack of knowledge on how various aspects of the interactive language environment in preschool relate to
BACKGROUND: Group 5 allergens, such as Phl p 5 of timothy grass, are major contributors to grass pollen allergy. Antibody 212597 specific for this allergen was recently isolated by single cell sequencing of bone marrow B cells of a grass pollen-allergic subject. This antibody, although subjected only to a low level of hypermutation resulting in six amino acid substitution across the heavy and ligh

This thesis describes a method for concluding attributes of a star (including ages, temperatures, chemical element abundances) from its spectra. The method was developed by the 4MOST (4-metre Multi-Object Spectroscopic Telescope) consortium. How the model outputs stellar attributes by receiving spectra is too complicated to be included in one thesis, so only introductions of numerical methods whic
The ABBI (Audio Bracelet for Blind Interaction) device is designed for visually impaired and blind children to wear on the wrist and produce sound based on the movement of the arm through space. The primary func- tion is to inform a child (or adult) about his/her own movements to aid spatial cognition rehabilitation. How- ever, the device could also be worn by friends and family and be used to inf
This thesis, which is based on four original papers, deals with human dendritic cells (DCs) in immunity and allergy. DCs play a key role in the regulation of immune responses by acting as the sentinels of the immune system, specialized in the uptake of a diverse range of antigens. These cells migrate to local lymph nodes and become highly efficient in inducing T cell proliferation, thus inducing a
We present an educational math game, including a teachable agent and an off-task conversation module in the form of a social chat. A recent study [1] indicates that the added off-task conversation module can i) improve students' game experience, ii) improve learning outcomes, and iii) engage learners in voluntary on-domain chat
The purpose of this paper has been to show how NMR diffusometry can be used to convey information about structure and dynamics of complex fluids. The information can be obtained without the need to invoke complicated models. In fact, simple reasoning pertaining to how a molecule may diffuse through the studied systems allows one to chose between different conceivable solution structures and to obt
Husserlian phenomenological theory is offered as an integrated and integrating for an understanding of management decision making and related issues in work and organizational sciences. The aspects of meaning, meaning constitution, subjective processes, and perspectives, mutual understanding of each other´s perspective, individuals as horizons of possible worlds are central to this conception, mak
The purpose of this paper is to discuss how theories of social and intellectual development of scientific fields can be used to analyze LIS, and especially its relationship to other research areas and the library and information field of practice. Scientific fields can be seen as reputational work organizations, where degrees of task uncertainty and mutual dependency control the coordination and d
