- A vertical temperature stratification normally exists in rooms during the heat-ing season in cold climates. An expression of the gradient in apartments heated by hydronic radiator heating systems with exhaust ventilation has ear-lier been developed assuming a dependency of the outdoor temperature. The expression was used by a public real estate owner when re-calculating meas-ured indoor temperature at 2.1 m above floor to 1.2 m above floor represent-ing the occupancy zone and used for individual metering and billing of space heating cost. To validate the suggested expression temperature measurements have been made at four heights in living rooms in apartments built in the 70’s. The heights includes 0.0, 0.1, 1.1 and 1.7 m above floor. The theoreti-cal expression has been compared to the full-scale measurements and in general the expression overestimates the vertical temperature gradient. The measured gradients are generally very low. The thermal comfort in the aspect of vertical temperature gradient is good for the studied period.

- Background: Few studies have investigated the health-related quality of life (HRQOL) in patients with melanoma in-transit metastases (ITM). The aim was to investigate the association between tumor burden and HRQOL, including disparities pertaining to sex and age, in treatment-naïve patients with ITM. Methods: Functional Assessment of Cancer Therapy-Melanoma (FACT-M) questionnaire was used to assess HRQOL Pairwise comparisons using t-tests between clinical cutoffs are presented and multiple linear regression analysis showing the unique associations of gender, age, number of tumors, tumor size, presence of lymph node metastases, and tumor localization. Results: A total of 95 patients, 47% females and 53% males (median age 72 years) were included between 2012 and 2021. Women scored significantly lower on emotional well-being (p = 0.038) and lower on FACT-M (p = 0.058). Patients who had ≥10 tumors scored significantly lower on FACT-M (p = 0.015), emotional- and functional well-being (p = 0.04, p = 0.004, respectively), melanoma scale (p = 0.005), and FACT-G (p = 0.027). There was no significant difference in HRQOL depending on age, size of tumors, localization, or presence of lymph node metastases. Conclusion: For patients with melanoma ITMs, the female sex and higher tumor burden (i.e., number of tumors) were significantly correlated with lower HRQOL. However, these findings do not fully explain HRQOL for this patient population, and future research should consider the possibility that there are specific questions for patients with ITM where current instruments might fail to measure their discomfort to the full extent.

Installation av Light Rail i Uppsala : GIS-baserad kollektivtrafikmodell
- 2000
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Rapporten redovisar resultaten från en förstudie vars huvudsyften är att, med stöd av GIS, planera en installation av ett kollektivtrafiksystem med applikation på en befintlig urban yta.- Dimensionera kollektivtrafiksystemet utifrån bebyggelsemönster och trafikgenerering.- Utveckla koncept för fordon (uttryckta som kravspecifikationer) och infrastruktur, som möjliggöreffektiv och attraktiv linjedragning och trafikföring i förhållande till bebyggelsestrukturerna.

Konferensbidrag (refereegranskat)abstract
- To calibrate methods for condition assessment of prestressed concrete (PC) bridges, tests were carried out on a 55 year old five-span bridge with a length of 121 m in Kiruna in northern Sweden. Both non-destructive and destructive full-scale tests were performed. This paper presents results regarding methods for assessment of the structural capacity of concrete bridges.
