Development of reference test specimens for the standardisation of active thermography with flash excitation

Abstract In this paper, results of a project concerning the development of a testing standard for active thermography with flash excitation are presented. In addition to the standardisation of the appropriate selection of equipment and procedures for testing and data analysis, the standard will describe suitable reference test specimens. These test specimens can be used for the qualification of the equipment as well as for the validation of the method including data processing concerning different areas of application

Factors Associated with Bone Level Alterations at Implants with Inner-Cone Connection and Platform Switching

Purpose.This retrospective cohort study evaluated factors for peri-implant bone level changes (ΔIBL) associated with an implant type with inner-cone implant-abutment connection, rough neck surface, and platform switching (AT). Materials and Methods. All AT placed at the Department of Prosthodontics of the University of Bern between January 2004 and December 2005 were included in this study. All implants were examined by single radiographs using the parallel technique taken at surgery (T0) and obtained at least 6 months after surgery (T1). Possible influencing factors were analysed first using t-test (normal distribution) or the nonparametric Wilcoxon test (not normal distribution), and then a mixed model q variance analysis was performed. Results. 43 patients were treated with 109 implants. Five implants in 2 patients failed (survival rate: 95.4%).Mean ΔIBL in group 1 (T1: 6–12 months after surgery) was −0.65 ± 0.82mm and −0.69 ± 0.82mm in group 2 (T1: >12 months after surgery)

Demographic, clinical and antibody characteristics of patients with digital ulcers in systemic sclerosis: data from the DUO Registry

OBJECTIVES: The Digital Ulcers Outcome (DUO) Registry was designed to describe the clinical and antibody characteristics, disease course and outcomes of patients with digital ulcers associated with systemic sclerosis (SSc). METHODS: The DUO Registry is a European, prospective, multicentre, observational, registry of SSc patients with ongoing digital ulcer disease, irrespective of treatment regimen. Data collected included demographics, SSc duration, SSc subset, internal organ manifestations, autoantibodies, previous and ongoing interventions and complications related to digital ulcers. RESULTS: Up to 19 November 2010 a total of 2439 patients had enrolled into the registry. Most were classified as either limited cutaneous SSc (lcSSc; 52.2%) or diffuse cutaneous SSc (dcSSc; 36.9%). Digital ulcers developed earlier in patients with dcSSc compared with lcSSc. Almost all patients (95.7%) tested positive for antinuclear antibodies, 45.2% for anti-scleroderma-70 and 43.6% for anticentromere antibodies (ACA). The first digital ulcer in the anti-scleroderma-70-positive patient cohort occurred approximately 5 years earlier than the ACA-positive patient group. CONCLUSIONS: This study provides data from a large cohort of SSc patients with a history of digital ulcers. The early occurrence and high frequency of digital ulcer complications are especially seen in patients with dcSSc and/or anti-scleroderma-70 antibodies

Longing for future living : Housing for tomorrow, based on yesterday

In this thesis, done in 2024 at the bachelor program Interior Architecture & Furniture Design, I give a proposal for an alternative future scenario for the cooperative housing organization HSB’s former headquarters at Fleminggatan 41, Kungsholmen, Stockholm. The office, built in 1939 by and for HSB, has after 84 years been passed on to a new owner and user, where the fate of the building is still unclear. I believe that the building should be of great historical value to HSB, especially since HSB’s former director Sven Wallander himself was the architect behind the building. In this work, I explore and propose future uses for the property under HSB’s ownership, and the possibility of going from office to residential through interior design. During the process of analyzing the building’s form and layout, the building turns out to be better suited for collective living with large, shared spaces, rather than private homes. For this reason, the work continues with inspiration from Sven Markelius’ collective housing on John Ericssons gata 6, also on Kungsholmen in Stockholm, which is also built during the same period as the head office (1935). In addition to historical functionalist references such as S. Markelius collective house and S. Wallander’s work for HSB’s history, The design proposal is also based on contemporary work by Andreas Martin-Löf, an architect who I believe has a strong connection to the functionalist ideology and aesthetics, and who has therefore been a great inspiration to the project in an effort to bring the ideas of functionalism further into the housing of the future. The result of the design proposal is a collective house with 75 identical residences of 29 square meters each, accommodating the most private room functions, designed according to the diversity of the households. The target group of this collective house is the social and child-free households of 1-2 persons who also have an interest in the collective lifestyle, and hope for the future. The residences are equipped with, among other things, bathtubs, oak parquet and window boards in swedish green marble, which is in line with the materials and functions associated with the functionalist era of HSB. On the ground floor of the house are the collective house’s common areas where spatial functions that can be shared with other residents take place. These areas include a laundry room with sewing machines and ironing boards, a mini spa, a home theater, a multifunctional living room and office, and a large kitchen for communal cooking and meetings, all of which are designed to meet the different needs and wishes of today’s households. With multiple shared spaces and functions, less is needed in the private home, which is both economically and ecologically sustainable. The aim of this work has been to create a modern interpretation of functionalism that reflects both historical and contemporary aesthetics, by creating a future oriented living environment.   Longing for tomorrow living.
