Popular Abstract in Swedish I denna avhandling presenteras tre studier som fokuserar på human serviceorganisationer, klientarbete, arbetstillfredsställelse och arbetsmiljö. Det övergripande syftet med denna avhandling var att med särskilt fokus på grad av direkt klientarbete och tillfredsställelse i arbetet undersöka arbetssituationen i olika typer av human serviceorganisationer. I den första stuIn this thesis, three empirical studies investigating human service organizations pertaining to client work, work satisfaction, and the work environment are presented. The general aim of this thesis was to investigate working conditions in human service organizations with particular consideration and emphasis on the extent of human service workers´ client work and their perceived level of job sati
This study is aimed at investigating and describing the different procedures of foreign language learners of Italian when they infer the meaning of unknown words in a written authentic text. Vocabulary is a crucial component in the learning process of a foreign language and many studies show that lexical inferencing is one of the most important strategies when foreign language learners encounter u
This work concerns two-dimensional numerical simulations of the flow and temperature fields inside smooth and ribbed bend (turn) parts of a U-duct with relevance for internal tip cooling of gas turbine blades. The ribs are placed internally on the outermost bend surface. The renormalization group (RNG) k-epsilon turbulence model was used to solve the momentum and energy equations inside the bend (
As part of systematic endeavor to Islamize the society, Iranian Islamic government has bestowed efforts to create gender-segregated public urban spaces. The gender segregation was formally enforced in public places such as schools, sport halls, swimming pools, transportation facilities, etc. in last three decades. The most recent effort of the government includes “women-only parks”, claimed to be
Systematic knowledge of entrepreneurship has evolved since the 1980s. In this study we will pay particular attention to the „knowledge producers‟ who have shaped the field over time but also to the „knowledge users‟ who have employed the core works in entrepreneurship in order to develop our knowledge of the phenomenon of entrepreneurship. A unique database consisting of all references in twelve „
Purpose of this paper This paper examines the use of unique identities (through RFID technology, bar codes, and “human-readable” labels) on packages and load carriers in Swedish manufacturing industries. The purpose is to investigate drivers behind the adoption, and the perceived improvements and visions for the coming 2-5 years. It also covers the use of different methods for reading the identiti
In a study on the problems of censorship and interpretation from 1984, (Censorship and Interpretation; The Conditions of Reading and Writing in Early Modern England), Annabel Patterson states that British authors of the seventeenth century often used the shelter of ambiguity as a protection from the threat of censorship. But as the text had to be understood by the intended readers, Patterson argue
A new technology has emerged the last decade, based on a new group of materials; Soft Magnetic Composites (SMC), instead of laminated steel that facilitates production of products with more integrated, smaller, lighter, less costly and highly efficient electromagnetic machines. The application of this technology is a change of paradigm regarding integrated design and energy efficiency. This articl
Identification of novel biomarkers for early diagnosis, prognosis, and treatment decision will be instrumental for improving disease outcome for patients suffering from complex diseases, such as cancer and autoimmune disorders. Within personalized medicine, the use of circulating biomarkers will allow clinicians to tailor medical treatment based on individual characteristics of each patient, using
Popular Abstract in Swedish Experimentella data från kollisioner mellan guldjoner vid hög energi har analyserat inom ramen för experimentet PHENIX, som finns vid en av kollisionspunkterna vid ''the Relativistic Heavy-Ion Collider'' på ''Brookhaven National Laboratory'', New York (USA). Kollisioner med tunga joner, så som guld, används i försök till att återskapa de förhållanden som fanns i univerThe properties of the basic building blocks of nuclear matter, the quarks, and their interactions are not known in detail, largely because observations are complicated by the confinement of quarks in composite particles. New insights can be gained from the study of nuclear matter in a deconfined phase, like the form of matter that the Universe consited of early in its evolution according to the Bi
Prostacyclin is the major arachidonic acid metabolite of the vascular endothelium and is produced mainly via the cyclooxygenase-2 pathway. By acting on the prostacyclin (IP) receptor on platelets and vascular smooth muscle cells, prostacyclin exerts vasodilatory and antiaggregative/antiadhesive effects. Previous studies have shown that prostacyclin production increases after brain trauma, but the
The properties of gas-borne aggregates are important in nano-technology and for potential health effects. Gold aggregates from three generators (one commercial and one custom built spark discharge generator and one high-temperature furnace) have been characterized. The aggregate surface areas were determined using five approaches - based on aggregation theory and/or measured aggregate properties.
Photosynthetic organisms need protection against excessive light. By using non-photochemical quenching, where the excess light is converted into heat, the organism can survive at higher light intensities. This process is partly initiated by the formation of zeaxanthin, which is achieved by the de-epoxidation of violaxanthin and antheraxanthin to zeaxanthin. This reaction is catalyzed by violaxanth
Running an internal combustion engine with diluted methane/air mixtures has a potential of reducing emissions and increasing efficiency. However, diluted mixtures need high ignition energy in a sufficiently large volume, which is difficult to accomplish. Increasing the spark duration has shown to be a promising way of delivering more energy into the diluted charge, but this requires a more sophist
I denna artikel analyseras möteskulturer och mötesstrider mellan olika professionella i ungdomsvården, samt det starka engagemang som ägnas åt dessa möten. Artikeln bygger på en studie av ett samverkansprojekt i ungdomsvården där ett antal samordnare anställdes. Det visade sig att dessa efter hand kom att upprätthålla en administrativ hållning gentemot varandra, vilket satte det direkt arbetet med
Certain species of the fungal genus Trichoderma are potent mycoparasites and are used for biological control of fungal diseases on agricultural crops. In Trichoderma, whole-genome sequencing reveal between 20 and 36 different genes encoding chitinases, hydrolytic enzymes that are involved in the mycoparasitic attack. Sequences of Trichoderma chitinase genes chi18-5, chi18-13, chi18-15 and chi18-17
Large seeds are assumed to have higher probability of successful recruitment than small seeds. This is because larger seeds give rise to larger seedlings and larger seedlings better withstand environmental hazards like deep shade and drought. Biotic and abiotic limitations to seedling growth and survival, and conversely availability of safe sites for recruitment, vary along environmental gradients
By catalyzing hydrolysis of cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP), cyclic nucleotide phosphodiesterases are critical regulators of their intracellular concentrations and their biological effects. As these intracellular second messengers control many cellular homeostatic processes, dysregulation of their signals and signaling pathways initiate or modulate p
