- OBJECTIVE: To evaluate the effects of a stress management intervention among 24 female patients on sick leave due to work-related psychological complaints. METHODS: The study design was quasi-experimental. All participants received a standard individual treatment for stress at a company healthcare unit. Half of the sample was also enrolled in a group intervention aimed at coping with psychological/somatic symptoms of stress. Data were collected before and after treatment and at 6- and 12-month follow-ups, through questionnaires and blood sampling. Rates of return to work were assessed for up to 5 years. RESULTS: Levels of depression decreased in both conditions and these improvements were maintained at follow-up. The experimental condition was superior in alleviating burnout, as measured with the Karolinska Exhaustion Scale. Paradoxically, these improvements were accompanied by significant increases in levels of glycated haemoglobin in both groups. At 5-year follow-up 40% of participants in both conditions had returned to work. CONCLUSION: The stress management intervention seems to have beneficial effects on self-rated symptoms, but is comparable to treatment as usual with respect to rates of return to work. More studies are needed to investigate the impact of this intervention on physiological parameters.

Journal article (peer-reviewed)abstract
- Well-crystallized flower-shaped cupric oxide (CuO) nanostructures composed of thin leaves have been synthesized by simple low-temperature chemical bath method and used to fabricate pH sensor. We examined the effect of the pH on the growth of the CuO nanostructures, by changing the pH of the precursor solutions different morphologies of the CuO nanostructures were obtained. CuO nanoflowers have recently become important as a material that provides an effective surface for electrochemical activities with enhanced sensing characteristics. The proposed sensor exhibited a linear electrochemical response within a wide pH range of (2-11). The experimental results (time response, electrochemical activity, reproducibility, absorption spectra, and XRD) indicate that the CuO nanoflowers can be used in pH sensor applications with enhanced properties.

Book chapter (other academic/artistic)abstract
- Embracing digitality is to a large degree a question of competence of critically understanding a branch of technologies, their use, usefulness and direct and indirect cultural repercussions. It is fair to claim that both quantitatively and qualitatively, there is more archaeological and archaeologically relevant information than before and new copious possibilities to use and reuse, analyse and reanalyse this information. A vital aspect in the process is to maintain a critical sensitivity to the limits of both large and narrow categories and an understanding of their consequences to archaeological information work and the conduct of archaeology. This is a task of all archaeological information workers from field archaeologists to geographic information system specialists, curators and information managers, and obviously, especially those who are engaged in educating and training future generations of professionals.

Journal article (peer-reviewed)abstract
- The Internet of Things (IoT) is a rapidly growing trend within many domains, such as automotive, avionics, automation, energy, and health. IoT architecture is the system of numerous elements, including sensors, protocols, actuators, cloud services, and layers. IoT architecture plays an important role to provide desired services. Nowadays, tens of IoT architectures are provided by the research community. Many challenges have been identified by the research community, including interoperability, security and privacy, reliability, energy constraints, scalability, and lack of common standards. However, to provide suitable IoT architecture, the importance and priority of requirements in different scenarios may vary, and requirement analysis should be regarded. To this end, this paper presents a systematic mapping survey to give a review of IoT architecture and provide a structured overview of research trends. Moreover, a technical taxonomy is presented for these challenges according to reviewed studies. This classification model can be used as a guideline for future works.

Journal article (peer-reviewed)abstract
- The 2004 H8 Testbeam setup is used as a test ground of various aspects of the ATLASdetector. The H8 study program focuses on sub-detector and trigger system performance in combined and standalone mode, as well as offline reconstruction and analysis, but leaves also space for specialized studies and experimental setups. In a dedicated setup,a BIS type Monitored Drift Tube chamber was placed in front of the Liquid ArgonCalorimeter and was attached to its support structure. The aim of this project is to perform positioning measurements of the Liquid Argon Calorimeter electrodes using the trackinformation from the BIS muon chamber. Moreover, the goal is to study the performance of the chamber in positron and muon beams at different beam incident angles. Last but not least, we investigate the correlation between the position of the cluster barycenter in the Liquid Argon and the reconstructed track in the BIS chamber.

Stereotactic body radiotherapy in non-small cell lung cancer
- 2009
-
Doctoral thesis (other academic/artistic)abstract
- Patients with stage I non small cell lung cancer (NSCLC) are potentially curable. Eradication of the primary tumour is a prerequisite for cure with surgery as standard treatment. A large part of NSCLC patients, in parallel to their cancer, also suffer from other smoke related diseases like chronic obstructive pulmonary disease (COPD) and cardio vascular diseases (CVD). In about 15 % of the patients with stage I NSCLC these coexisting diseases confer inoperability. With conventionally fractionated radiotherapy (CFRT) local tumour control is obtained in less than 50% of stage I NSCLC patients. This is related to limitations in permissive dose mainly due to risk of unacceptable toxicity in surrounding normal lung parenchyma. With stereotactic body radiotherapy (SBRT) doses high enough to sterilize the tumour, without excessive toxicity in normal tissue, can be delivered. The aim of this doctoral thesis and the underlying papers has mainly been to collect clinical evidence for a role of SBRT in the treatment of NSCLC. In the thesis, outcome and toxicity were analyzed in a retrospective and a prospective study on stage I NSCLC in altogether 195 patients treated with SBRT. COPD or CVD was the main reason for inoperability among the patients. The total radiation doses given had a median peripheral biologic effective dose (BED10) of 113 Gy and a central dose of 211Gy. Median follow up was 3 years. Local tumour control rate was 88% in the retrospective (ret.) and 92% in the prospective (pro.) study. Only 5% (pro.) and 7% (ret.) of the patients experienced regional failure. During follow up, distant metastases were recorded in 16% (pro.) and 25% (ret.) of the patients. Overall survival at 3-years was 52% (ret.) and 60% (pro.) but lung cancer specific survival was 66% (ret.) and 88% (pro.), a difference that likely is explained by death due to co-morbidity. To further develop SBRT a better understanding of the risk of toxicity is needed. This is especially important in patients with COPD who already have an impaired lung capacity. On the whole, toxicity after SBRT was mild and in 59% (ret.) and 21% (pro.) of the patients no side-effects were recorded. Objective lung function measured as forced expiratory volume in 1 second (FEV1%) did not decrease more than what is expected in a non-irradiated patient cohort, during the follow-up period. Clinically important toxicity was seen in 10% (ret.) and 30% (pro.) where dyspnoea and thoracic pain were most common. No significant difference was seen between COPD and CVD patients. Notable is that COPD patients with the poorest lung function tolerated SBRT to the same extent as other patients. In SBRT of lung tumours no established relationship between dose-volume parameters and the incidence of clinical radiation pneumonitis (RP2+) has been shown which is contradictory to the situation with conventionally fractionated radiotherapy (CFRT). Dose-volume-histogram (DVH) and toxicity data from the prospective study was used for normal tissue complication probability (NTCP) modelling. DVH data was corrected to 2 Gy/fraction using the universal survival curve (USC) model as well as the LQ model with á/â of 3 Gy and 20 Gy. In SBRT of lung tumours NTCP modelling with USC used for fractionation correction, resulted in a more serial architecture of functional subunits in the lung than what is seen after CFRT. In conclusion, SBRT for early stage lung cancer provides local control rates similar to what is obtained with surgery. SBRT is also well tolerated with only limited side-effects even in patients with markedly decreased pulmonary function. The calculated risk of pneumonitis, using the models in this study, depended relatively more on the volume with the highest doses than what is seen after CFRT. Overall survival is favourable compared to other nonsurgical treatments and lung cancer specific survival is excellent and with these results it is reasonable to conclude that SBRT should be offered to medically inoperable patients with stage I NSCLC.
