The Swedish Case Study, Fire Safety Design for a Multitenant Business Occupancy
The report presents a sample design of a multi-storey building with respect to the fire safety. Three design strategies are examined, a standard solution according to the requirements, a fire safety engineering design without a sprinkler system and finally a fire safety engineering solution with a sprinkler system. Both occupant safety and structural safety have been considered in the design for t
Epidemiology of hand injuries in a middle-sized city in southern Sweden: a retrospective comparison of 1989 and 1997.
Virologic versus cytologic triage of women with equivocal pap smears: A meta-analysis of the accuracy to detect high-grade intraepithelial neoplasia
Background: The appropriate management of women with minor cytologic lesions in their cervix is unclear. We performed a meta-analysis to assess the accuracy of human papillomavirus (HPV) DNA testing as an alternative to repeat cytology in women who had equivocal results on a previous Pap smear. Methods: Data were extracted from articles published between 1992 and 2002 that contained results of vir
Identification of a mitochondrial external NADPH dehydrogenase by overexpression in transgenic Nicotiana sylvestris
The plant respiratory chain contains a complex setup of non-energy conserving NAD(P)H dehydrogenases, the physiological consequences of which are highly unclear. An expression construct for the potato (Solanum tuberosum L., cv. Desiree) ndb1 gene, a homologue of bacterial and fungal type II NAD(P)H dehydrogenases, was introduced into Nicotiana sylvestris. Transgenic lines with high transcript and

Mechanisms behind the faceting of catanionic vesicles by polycations: Chain crystallization and segregation
Vesicles composed of an anionic and a cationic surfactant, with a net negative charge, associate strongly with a hydrophobically modified polycation (LM200) and with an unmodified polycation with higher charge density (JR400), forming viscoelastic gel-like structures. Calorimetric results show that in these gels, LM200 induces a rise of the chain melting temperature (T-m) of the vesicles, whereas
Hepatitis C superinfection in hepatitis C virus (HCV)-infected patients transplanted with an HCV-infected kidney
Hepatitis C virus (HCV) genotypes, determined by polymerase chain reaction with type-specific primers, were studied in 5 already HCV-infected patients receiving kidneys from HCV-infected cadaver donors. Three patients were investigated retrospectively using stored pre- and posttransplantation sera and followed 18-28 months after transplantation. Two recipients with HCV genotype 2b infection had re

Protective clothing in hot environments
The high level of protection required by personal protective clothing (PPC) severely impedes heat exchange by sweat evaporation. As a result work associated with wearing PPC, particularly in hot environments, implies considerable physiological strain and may render workers exhausted in a short time. Recent development of algorithms for describing the heat transfer, accounting for pumping and wind
Vertical high-mobility wrap-gated InAs nanowire transistor
In this letter, the authors demonstrate a vertical wrap-gated field-effect transistor based on InAs nanowires [Proc. DRC, 2005, p. 157]. The nanowires have a diameter of 80 nm and are grown using selective epitaxy; a matrix of typically 10 x 10 vertically standing wires is used as channel in the transistor. The authors measure current saturation at V-ds = 0.15 V (V-g = 0 V), and a high mobility, c

Pipeline break detection using pressure transient monitoring
Sudden pipe breaks occur in water transmission pipelines and distribution mains. The consequences of these breaks can be very expensive because of the service interruption, the cost of repair, and damage to surrounding property and infrastructure. The costs associated with the pipeline breaks can be reduced by minimizing the break detection and location time. This paper presents a new continuous m
Soil microbial community structure in relation to vegetation management on former agricultural land
Agricultural overproduction has led the European Union to encourage long-term abandonment of agricultural land. To enhance the transition of agricultural land to natural grasslands or forests different management practices in relation to vegetation can be used. The aim of this study was to understand the interactions between plant and associated soil microbial communities during the succession of
Stories of Achievements - Narrative Features of Organizational Performance
Stories of achievements is a study concerning uses of the notion of organizational performance. It shows the variety of meanings given the notion in dictionaries, management literature, sports, and performance indicators; it also explores how such meanings are constructed and how they are attached to this notion in new contexts, such as in the activity reports of public libraries. Examining uses
Effects of estradiol and medroxyprogesterone acetate on morphology, proliferation and apoptosis of human breast tissue in organ cultures
Background: Human breast tissue undergoes phases of proliferation, differentiation and regression regulated by changes of the levels of circulating sex hormones during the menstrual cycle or aging. Ovarian hormones also likely play a key role in the etiology and biology of breast cancer. Reports concerning the proliferative effects of steroid hormones on the normal epithelium of human breast have

The Swedish Knee Arthroplasty Register 1975-1997: an update with special emphasis on 41,223 knees operated on in 1988-1997
From 1975, when the Swedish Knee Arthroplasty Register (SKAR) started, until the end of 1997, 57,533 primary arthroplasties and revisions have been registered. Recently, the register underwent a comprehensive validation and update regarding revisions. We now report on general demographic and epidemiological data for the whole period and on the survivorship of arthroplasties performed in Sweden dur
Developmental phenotypic plasticity in embryos during incubation
Bird embryos depend on the attendance of parents to provide the optimal temperature for development. When parents cannot incubate optimally, the embryos need to adjust rates of growth and modes of development to compensate. I review data on the plasticity of embryo growth in birds, and relate this to mode of incubation, climate, nest insulation, and the continuum between precocial and altricial sp
