The dissolved air flotation process is used in water and wastewater treatment. Among many parameters the fluid dynamics determine the capacity of the process. The contact zone is assumed to be important for the removal function, as it is believed to be the location for the aggregation of bubbles and flocs. This paper presents an experimental study on the flow structure in a contact zone of a DAF p

This article presents an overview of the literature on speech tempo and the topics dealt with. Tempo is not one of the more frequently explored areas of speech research, and any possible consequences of tempo variation for other phonetic phenomena have all too often been taken for granted. Unfortunately, this field is complicated by pitfalls of definition and hazards of numerical treatment. A gla

The purpose of this paper is to study the transfer of knowledge between preparedness activities and emergency response at the municipal level to improve emergency response. Design/methodology/approach - A case study was carried out in the municipality of Ljungby using prewritten questions to analyse the collected empirical material. This material consisted of both municipality documents and interv

Species of the Lactobacillus acidophilus complex are generally considered to constitute most of the vaginal Lactobacillus flora, but the flora varies between studies. However, this may be due to difficulties in identifying the closely related species within the L. acidophilus complex by using traditional methods and to variations in the vaginal status of the participants. Two hundred two isolates

BACKGROUND: Genome-wide association studies (GWAS) identified variants at 19p13.1 and ZNF365 (10q21.2) as risk factors for breast cancer among BRCA1 and BRCA2 mutation carriers, respectively. We explored associations with ovarian cancer and with breast cancer by tumor histopathology for these variants in mutation carriers from the Consortium of Investigators of Modifiers of BRCA1/2 (CIMBA). METHO

This dissertation is a collection of seven papers in which a number of questions are investigated regarding verbs that take a sentential complement as their direct object. These verbs are considered from different perspectives, namely from the perspective of the propositional attitude they express, or from the perspective of the syntactic construction they select, or from the point of view of the

During development primary afferents grow into and establish neuronal connections in the spinal cord, thereby forming the basis for how we perceive sensory information and control our movements. In the somatosensory system, myriads of primary afferents, conveying information from different body locations and sensory modalities, get organized in the dorsal horn of the spinal cord so that spinal mul

Visible-UV fluorescence emission of gas-phase hydrogen sulfide, H(2)S, has been studied at the S 2p edge with synchrotron radiation excitation. Dispersed fluorescence measurements in the wavelength range 300-900 nm were taken at several photon energies corresponding to the excitations of the S 2p electrons to the unoccupied molecular and Rydberg orbitals. The spectra reveal fluorescence from the H

In the present article we give a general three-dimensional formalism for scattering in two half spaces, one of which contains a bounded inhomogeneity. Our formalism consists of an extension of the transition matrix method which has been given by Waterman, a method which applies equally well to acoustic, electromagnetic, and elastic scattering. The formalism is here developed in detail for the case
