- AIM: To evaluate the effects of acupuncture in patients with keratoconjunctivitis sicca (KCS).MATERIAL AND METHODS: Twenty-five patients (20 women, five men) with KCS were randomly assigned to an acupuncture treatment group or a control group. The effects of acupuncture were evaluated by a questionnaire on symptoms, visual analogue scale recordings, registration of drop frequency, and dry eye tests. Ten acupuncture sessions were given. Follow-up was carried out after 2-3 weeks and again after a mean period of 8 months.RESULTS: Patients receiving acupuncture felt better at the first follow-up compared with the control group (p = 0.036). However, no statistical significance could be found concerning any change, or difference, in the total number of subjective symptoms, dosage frequency or, as indicated by the dry eye tests, tear quality, tear secretion and ocular surface disease.CONCLUSION: The results indicate that acupuncture has subjective beneficial effects in patients with KCS and could therefore be tried as a complement to ordinary treatment.

Miljöbedömning och miljöbeskrivning i väg- och järnvägsprojekt : Vägledning
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Denna vägledning förmedlar Trafikverkets syn på hur de båda processerna miljöbedömning och miljöbeskrivning bör tillämpas i planläggning och projektering av väg- och järnvägsprojekt, med utgångspunkt från lagkrav, praxis och Trafikverkets erfarenheter. Den tar även upp innehållet i de båda dokumenten miljökonsekvensbeskrivning och miljöbeskrivning som kommer ut av de båda processerna. Vägledningen syftar till att bidra till integrering av miljöaspekter i planläggning och projektering av vägar och järnvägar samt till en god kvalitet på genomförande och redovisning. Den syftar även till att miljöbedömningar och miljöbeskrivningar ska genomföras på ett likartat sätt i hela Trafikverket och få en jämn kvalitet. Vägledningen riktar sig främst till Trafikverkets konsulter och egna miljöspecialister som gör miljöbedömningar och miljöbeskrivningar i Trafikverkets väg- och järnvägsprojekt. Vägledningen ersätter Trafikverkets Handbok om metodik för miljökonsekvensbeskrivning för vägar och järnvägar (Trafikverket 2011:090). Den ersätter också texter om MKB och miljöbeskrivning i Trafikverkets Rapport planläggning av vägar och järnvägar. Vägledningen innehåller bland annat:relevant lagstiftning och målbeskrivning om hur miljö integreras samt miljöbedömningens roll och moment i planläggningens olika skedensamråd, samrådsunderlag, utredning om betydande miljöpåverkan och miljökonsekvensbeskrivningens (MKB) innehåll Trafikverkets syn på hantering av miljöaspekter, behov av att koppla dessa till miljöintressen för vilka konsekvenser beskrivs

- Tree biotechnology will soon reach a mature state where it will influence the overall supply of fiber, energy and wood products. We are now ready to make the transition from identifying candidate genes, controlling important biological processes, to discovering the detailed molecular function of these genes on a broader, more holistic, systems biology level. In this paper, a strategy is outlined for informative data generation and integrated modeling of systematic changes in transcript, protein and metabolite profiles measured from hybrid aspen samples. The aim is to study characteristics of common changes in relation to genotype-specific perturbations affecting the lignin biosynthesis and growth. We show that a considerable part of the systematic effects in the system can be tracked across all platforms and that the approach has a high potential value in functional characterization of candidate genes.

Establishment of Photosynthesis through Chloroplast Development Is Controlled by Two Distinct Regulatory Phases

Tidskriftsartikel (refereegranskat)abstract
- Chloroplasts develop from undifferentiated proplastids present in meristematic tissue. Thus, chloroplast biogenesis is closely connected to leaf development, which restricts our ability to study the process of chloroplast biogenesis per se. As a consequence, we know relatively little about the regulatory mechanisms behind the establishment of the photosynthetic reactions and how the activities of the two genomes involved are coordinated during chloroplast development. We developed a single cell-based experimental system from Arabidopsis (Arabidopsis thaliana) with high temporal resolution allowing for investigations of the transition from proplastids to functional chloroplasts. Using this unique cell line, we could show that the establishment of photosynthesis is dependent on a regulatory mechanism involving two distinct phases. The first phase is triggered by rapid light-induced changes in gene expression and the metabolome. The second phase is dependent on the activation of the chloroplast and generates massive changes in the nuclear gene expression required for the transition to photosynthetically functional chloroplasts. The second phase also is associated with a spatial transition of the chloroplasts from clusters around the nucleus to the final position at the cell cortex. Thus, the establishment of photosynthesis is a two-phase process with a clear checkpoint associated with the second regulatory phase allowing coordination of the activities of the nuclear and plastid genomes.

- In Swedish sawmills, about 70% of the total costs can be derived from raw-material costs. Hence, it is very important for sawmills to obtain the highest possible yield. The green target size is an important parameter that affects the yield. The nominal size, sawing allowance, shrinkage allowance and planer allowance add up to the green target size that is needed when sawing lumber. We have, in this work, studied whether it is possible to adaptively control the green target size by measuring log density and annual ring width with an X-ray Log Scanner online. Our hypothesis was that density and growth speed will affect how much every single piece of lumber will shrink.The results show that both density and annual ring width are rather weak variables for prediction of lumber shrinkage. The variable "distance to pith", i.e., where in the log cross-section a piece of lumber has been cut, has proved to be a significant variable for prediction of lumber shrinkage. The results show that the yield can be considerably improved by adapting the green target size to how far from the pith every piece of lumber is cut.

Flexibilitetens gränser : Förändring och friktion i arbetsliv och familj
- 2004
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- THE TERM FLEXIBILITY has come to be a symbol for a number of grand hopes. An increased flexibility is seen as a key issue for modern organisations and is assumed to pave the way for a more gender equal and family friendly working life. The aim of the thesis has been to confront a number of assumptions about the “flexibilization” of working life with quantitative data from the Swedish labour market. An important goal has been to discuss the effects of flexibility on gender segregation in work and family life. The study focuses on three branches with different gender composition of the work force: manufacturing, health care and finance. The main data consists of a questionnaire that was sent to a representative sample of employees in the three branches (n=1.836) and another that was sent to their workplaces (n=625). Addional data comes from interviews with representatives of labour unions and employer organisations, and reviews of collective agreements and of- ficial statistics. The results provide a picture of flexibility in working life that differs from the one depicted in the ongoing debate, both regarding the strategies of organisations and the significance of flexibility to employees. The debate has focused on expanding employers’ room to manoeuvre, especially the possibilities to hire and fire personnel according to shifts in demand. The thesis shows, however, that efforts to create flexibility within the existing work force, through for instance overtime and work rotation, are equally important as the numerical flexibility obtained through termination of personnel, temporary jobs and sub-contracting. The results also challenge the idea that labour market regulation constitutes a decisive obstacle for flexibility. Workplaces that regard regulation as a problem do not adapt staffing to demand any less than others do and in all three branches competence issues pose a greater problem. The analyses point to a somewhat ambiguous relationship between gender and flexibility. Women have less employeroriented flexible work hours than men, which could be a result of their greater responsibility for home and children, but despite this responsibility they have less of a possibility to set their own working hours. This is explained by the fact that influence over work hours is an organisational perk associated with a high position and an adaptation to employer needs, rather than a right for the employee. Demands on time from the family in the form of children or a greater responsibility for housework do not affect the possibilities for flexible work schedules. The thesis also gives cause to question the idea that flexible work hours make it easier to combine paid work and family. Flexibility does not seem to lessen the conflict between these two spheres, nor does it lead to a more egalitarian division of housework. Functional flexibility in the form of work rotation and other forms of varying work tasks leads to job enrichment, but also to an intensification of work This kind of flexibility is not more common among men than women and there is no gender difference regarding its effects on work.

Introducing e-Gov : history, definitions, and issues
- 2005
-
Ingår i: Communications of the Association for Information Systems. - 1529-3181. ; 15, s. 39-
-
Tidskriftsartikel (refereegranskat)abstract
- The e-Gov field (also called Electronic Government, Digital Government, Electronic Governance, and similar names) emerged in the late 1990´s. Since then it spurred several scientific conferences and journals. Because the field grew considerably in size, both its contents and position with respect to other research fields and disciplines need to be explained and discussed. What is e-Gov? What is e-Gov research? What does it mean for the field of Information Systems? This paper briefly sketches the short e-Gov history and current status, and discusses the content of the field as it appears in current research. We conclude with a discussion of e-Gov as a research field of interest both as a new application area for IS theories and methods and as a source of new insight.
