The primary purpose of this work was to study and analyze the MSB's training with respect to building fire protection and propose changes in training. The area studied is operational aspects of building fire protection, ie how this protection affects the ability to implement effective response from fire service organizations. The main conclusions were that the training must distinguish between new

The objective of the present work was to create a basis for further development on training for part-time firefighters. An important prerequisite of this work was that to the general public a firefighter is a firefighter and operations are expected to be conducted in the same manner, with similar efficiency and with good result, regardless of the type of resources arriving at the scene of an accid

This report summarizes the work in practically determining how frequently used aerosol- and propane containers are affected at fire exposure from flammable liquids. The tested aerosol- and propane containers were chosen due to common appearance in ordinary grocery- and hardware stores. The tested aerosol containers had a volume range between 15- 400 ml and the propane containers were filled with 0

The purpose of this work was to experimentally examine the importance of safety devices (pressure valve and melting fuse) on propane bottles for consumer use (5 – 6 kg propane). The bottles tested included construction types based on composite (PK5, two different types), aluminum (PA6), and steel (P6). Bottles were tested with and without safety devices. The tests were made as a comparative study.

Positive pressure ventilation (PPV) has been used by the fire service for a number of years as a procedure to remove smoke and hot gases from a building on fire. PPV is a procedure where air is pushed into a building exposed to fire with the help of fans, consequently pushing hot air and smoke out of the building. This paper summarizes a large number of studies on PPV, draws conclusions from these

There is a great need to quantify the efficient use of resources during fire fighting operations. When addressing this problem, the focus should be on the results of such operations. This paper describes a number of approaches for quantifying fire fighting operations. Also, it identifies and discusses a number of aspects that has to be considered during such work, including inherent complexity, m

Caveolae are abundant adipocyte surface domains involved in insulin signaling, membrane trafficking and lipid homeostasis. Transcriptional control mechanisms for caveolins and cavins, the building blocks of caveolae, are thus arguably important for adipocyte biology and studies in this area may give insight into insulin resistance and diabetes. Here we addressed the hypothesis that one of the less

Positive pressure ventilation was investigated. Forty-three experiments were performed on the first, second, and third floors of a three-storey brick building with wooden trusses. The objectives of the experiments were to investigate the effects of distance between fan and inlet, size and numbers of outlets, and volume of building on vent flow rates when using positive pressure ventilation. Four d

Context: De novo brain tumors developing after treatment of pituitary/sellar lesions have been reported, but it is unknown whether this is linked to any of the treatment modalities. Objective: To study the occurrence of malignant brain tumors and meningiomas in a large cohort of patients treated for pituitary/sellar lesions, with special emphasis on the role of radiotherapy (RT). Patients and Meth

This paper presents datasets that enable historical longitudinal studies of micro-level geographic factors in a rural setting. These types of datasets are new, as historical demography studies have generally failed to properly include the micro-level geographic factors. Our datasets describe the geography over five Swedish rural parishes, and by linking them to a longitudinal demographic database,
