Microbial growth in coal slurries can be detected if surfactant is present in the samples by analysing the protein concentration after disintegration of the cells. Without surfactant present in the samples, the proteins are readily adsorbed on the coal surfaces. A suitable surfactant is sodium dodecyl sulphate at 0.5 to 1% of the sample volume
The objective was to explore the meaning of the phenomenon of problem solving in midwifery when the midwife is faced with a critical situation in the absence of an obstetrician or any physician. A qualitative method was used and critical incidents from delivery wards and/or antenatal clinics in the south of Sweden were narrated by midwives and transcribed verbatim. The interwievs were then analyse
We present a semi-empirical equation for prediction of the strengths of those N III lines that are generated by the Bowen mechanism and observed in spectra of symbiotic stars. The equation assumes that the Bowen mechanism is the only source populating the 3d state in N III, and comparisons with observations of the 3s-3p and 3p-3d transitions serve as a test of this assumption. In an ongoing study
In a 24-year sub-sample taken from a 42-year period of study (1950-1991), hip fracture incidence was analysed from a defined catchment area within one hospital. During this time, 8,256 hip fractures occurred in a generated risk population of 1,915,571 person-years. Crude incidence increased three-fold in women and five-fold in men. In men, the age-specific increase was twice as large as the age dr
OBJECTIVES: To study the background and the working and socio-economic conditions, and the prevalence of some sexually transmitted diseases (STDs), among street and sex club female Latvian prostitutes. STUDY DESIGN: Structured in-depth interviews, as well as clinical examination and laboratory tests for gonorrhea, syphilis, bacterial vaginosis, trichomoniasis, ectoparasites and HIV-infections. RES
Patients receiving oral anticoagulant treatment have abnormally low levels of functional vitamin K-dependent coagulation proteins and consequently a clear risk of hemorrhagic complications. The incidence of hemorrhages has been reported to be around 0.6-0.7% per month at a therapeutic International Normalized Ratio (INR) and the incidence of major hemorrhagic events is substantial. Therefore, the
The nigrostriatal dopamine (DA) system has an essential role in the selection and control of movement sequences, and its degeneration causes the characteristic motor symptoms of Parkinson's disease. Parkinsonian motor symptoms are alleviated by l-DOPA, but this treatment induces motor fluctuations and dyskinesias (abnormal involuntary movements). Clinical and experimental findings indicate that th
The purpose of this study was to investigate those parts of the care of hospitalized children that their parents perform, the nursing tasks the parents themselves felt they could manage and whether parents' and staff members' opinions coincided. A questionnaire was given to parents of children between one week and five years of age who were hospitalized at a pediatric surgical department during a
An algal-bacterial consortium was tested for the treatment from a coke factory. A Chlorella vulgaris strain and a phenol-degrading Alcaligenes sp. were first isolated from the wastewater treatment plant to serve as inocula in the subsequent biodegradation tests. Batch tests were then conducted with samples from the real wastewater or using a synthetic wastewater containing 325 mg phenol/l and 500
We present a functional limit theorem for the empirical level-crossing behaviour of a stationary Gaussian process. This leads to the well-known Slepian model process for a Gaussian process after an upcrossing of a prescribed level as a weak limit in C-space for an empirically defined finite set of functions.We also stress the importance of choosing a suitable topology by giving some natural exampl
BACKGROUND AND PURPOSE: It is unclear whether stroke in patients with spontaneous dissection of the cervical internal carotid artery (ICAD) is due to thromboembolism or impaired hemodynamics. This study investigated the mechanism of stroke in ICAD by examining brain imaging and cerebrovascular findings of such patients. METHODS: We retrospectively evaluated the prospectively collected brain CT, MR
An experimental model is presented that allows qualitative as well as quantitative studies of the soft tissue response to implant materials used in reconstructive surgery. Plugs of non-alloyed titanium and polymers (Teflon, Delrin) were inserted into the abdominal wall of rats, with a portion of the plug penetrating through the peritoneum into the abdominal cavity. The tissue reaction was evaluate

The dynamics of visible-to-ultraviolet upconversion in YAlO3: 1% Er3+ crystal has been investigated using the time-resolved laser spectroscopy when the sample was excited into the S-4(3/2) multiplets. It is found that the upconverted luminescence is produced by energy-transfer upconversion or by excited-state absorption depending on the excitation wavelength. The dependence of upconverted luminesc
A hidden Markov regime is a Markov process that governs the time or space dependent distributions of an observed stochastic process. Recursive algorithms can be used to estimate parameters in mixed distributions governed by a Markov regime. Here we derive a recursive algorithm for estimation of parameters in a Markov-modulated Poisson process also called a Cox point process. By this we mean a doub
The portal appearance of enteral alpha-ketoglutarate (AKG) and the effect of enteral or parenteral AKG on portal net appearance of glucose, short-chain fatty acids, alanine, aspartate, glutamate, glutamine, proline and insulin were investigated in three growing pigs. During the experimental samplings the pigs were fed hourly with a standard feed mix with 5% glucose (control), 5% AKG (enteral) or n
The intracellular signal cascade transducing muscarinic-receptor-stimulation to gene expression was investigated in human neuroblastoma SH-SY5Y cells. Naive and ethanol-exposed SH-SU5Y cells were stimulated with carbachol (CCh) and inositol 1,4-5-trisphosphate (IP3), 1,2-diacylglycerol (DAG), and c-fos mRNA levels were analyzed using a radioreceptor assay (IP3) thin-layer chromatography (DAG) and
