Correlation Between Firefighting Operation and Fire Area: Analysis of Statistics

The aim of this study is to investigate whether current statistics can quantify the benefits of fire brigades. A detailed investigation by the London Fire Brigade of most fires in the greater London area has been underway since 1994. The present study concerns 307 fires in non-residential buildings between 1994 and 1997. Times to detection, to arrival of the fire brigade, and to extinguishment of

Screening for heterocyclic amines in chicken cooked in various ways.

Chicken cooked under well-controlled conditions and commercial chicken products were screened for heterocyclic amines (HAs). Chicken samples were boiled, deep-fried, pan-fried, oven-roasted, cooked in an unglazed clay pot or in a roasting bag in the oven, and oven broiled. 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx), 2-amino-3,4,8-trimethylimidazo[4,5-f]quinoxaline (4,8-DiMeIQx), 2-amino

Bone mineral density in athletes during and after career: a comparison between loaded and unloaded skeletal regions

Bone mineral density (BMD) was measured in the upper part of the skull, the femoral neck, and the total body by dual energy X-ray absorptiometry in 56 male and 33 female active athletes, 18-40 years of age, together with 64 male ex-weight lifters, 35-79 years of age. The active athletes were compared with 41 male and 54 female controls, the ex-weight lifters with 133 male controls. The purpose of

Characterization of women with a history of recurrent vulvovaginal candidosis.

Background. To characterize history, signs, and symptoms in women with a history of recurrent vulvovaginal candidosis (RVVC) and who had consulted with symptoms generally associated with the condition. Methods. Eighty-three women with a history consistent with RVVC were interviewed regarding 32 parameters and 10 signs found at the clinical examination were noted. Candida cultures were made from t

Gas6 and protein S. Vitamin K-dependent ligands for the Axl receptor tyrosine kinase subfamily.

Gas6 and protein S are two homologous secreted proteins that depend on vitamin K for their execution of a range of biological functions. A discrete subset of these functions is mediated through their binding to and activation of the receptor tyrosine kinases Axl, Sky and Mer. Furthermore, a hallmark of the Gas6-Axl system is the unique ability of Gas6 and protein S to tether their non receptor-bin

Mutated alleles of the rod and cone Na-Ca+K-exchanger genes in patients with retinal diseases

PURPOSE. To study the possible involvement of the rod (SLC24A1) and cone (SLC24A2) Na-Ca+K exchanger (NCKX) genes in retinal diseases. METHODS. DNA was collected from unrelated patients with retinal disease, mainly from North America. A human genomic library was screened with the cone NCKX cDNA, and hybridizing clones were sequenced to determine the genomic organization of the SLC24A2 gene. The si

Amble FR, Lindberg SOH, McCaffrey TV, Runer T. Mucociliary function and endothelins 1, 2, and 3. Otolaryngol Head Neck Surg 1993;109:634-45.

Endothelins are recently discovered peptides that cause vasoconstriction and bronchoconstriction. The significance to the mucociliary system of endothelins (ET) 1, 2 and 3 in upper as well as lower airways has not yet been clarified. Effects of these active peptides were investigated, combining both in vitro and in vivo rabbit models of mucociliary activity from the maxillary sinus and the trachea

On the shape and duration of FM clicks

The stochastic behavior of FM-clicks in an unmodulated carrier plus noise is studied in terms of the conditional behavior of stationary Gaussian processes after level crossings. By a systematic use of thc Slepian model processes it is shown that the normalized shape of a positive FM-click approaches a certain rational function with simple random coefficients as the carrier-to-noise ratio tends to

Suboptimal dynamic programming with error bounds

This paper presents a method to relax Dynamic Programming. The methodmakes it possible to findsuboptimal solutions with known error bounds to hard problems.The bounds are chosen by the user, who can then effectively trade-offbetween solution time and accuracy. Several examples from differentdomains where the method is highly useful are presented.

Lack of HIN-1 methylation in BRCAl-linked and "BRCA1-like" breast tumors

We recently identified a candidate tumor suppressor gene, HIN-1, that is silenced due to methylation in the majority of sporadic breast carcinomas and is localized to 5q33-qter, an area frequently lost in BRCA1 tumors and thought to harbor a BRCA1 modifier gene. To establish whether germ-line mutations in HIN-1 may influence breast cancer risk, we sequenced the HIN-1 coding region in 10 familial b

Some ecophysiological and historical approaches to species richness and calcicole/calcifuge behaviour - Contribution to a debate

Species richness in vascular plants was related to the plants' calcifuge or calcicole behaviour using documentation from forests and open-land vegetation at about one thousand sites in the southern parts of Sweden. It is concluded that vegetation of strongly acid soils (pH-KCl < 4.5) have fewer vascular plant species than comparable vegetation of other soils, whereas there are no consistent differ

Islet antibodies and remaining beta-cell function 8 years after diagnosis of diabetes in young adults: a prospective follow-up of the nationwide Diabetes Incidence Study in Sweden.

Objectives. To establish the prevalence of remaining beta-cell function 8 years after diagnosis of diabetes in young adults and relate the findings to islet antibodies at diagnosis and 8 years later. Design. Population-based cohort study. Setting. Nationwide from all Departments of Medicine and Endocrinology in Sweden. Subjects. A total of 312 young (15-34 years old) adults diagnosed with diabe

Artikeln diskuterar den senmedeltida myntningen i Lund med anledning av en arkeologisk undersökning utförd av Kulturen i kv. Myntet, Lund. I kvarteret har det senmedeltida myntverket varit lokaliserat. I undersökningen påträffades rikliga mängder med deglar efter metallhantverk.

Alternative techniques in trochanteric hip fracture surgery. Clinical and biomechanical studies on the Medoff sliding plate and the Twin hook.

Popular Abstract in Swedish Nya operationsmetoder för trokantära höftfrakturer – klinisk och biomekanisk utvärdering av Medoff´s glidplatta och Twin hook Akademisk avhandling av Ola Olsson Sammanfattning på svenska Benskörhet är en folksjukdom som bidrar till uppkomst av en rad typfrakturer. Till dessa hör höftfrakturer, som utgör ett folkhälsoproblem och en stor utmaning för samhällets sjuvårdsIn allowing compression along the femoral shaft (uniaxial dynamization) and optional compression along the femoral neck (biaxial dynamization), the Medoff sliding plate (MSP) represents a new principle in the fixation of trochanteric hip fractures. The Twin hook with 2 apical hooks was designed as an alternative to the lag screw. In 3 prospective consecutive case series and 1 prospective randomize

Periarticular bone mineral content in rheumatoid arthritis and arthrosis of the hip. Dual photon X-ray absorptiometry in 53 cases

The bone mineral content (BMC) was determined by dual photon X-ray absorptiometry prior to hip replacement in 22 patients with rheumatoid arthritis and 31 with arthrosis. Compared with the arthrosis patients, the rheumatoids had approximately 20 percent lower bone mineral content in the proximal femur, the lumbar spine, and in the innominate bone superior to the acetabulum.
