Attention is drawn to some of the limitations of conventional plume theory, some differences between axi-symmetric and line plumes, and some rationalisation which is possible in correlating data for the flow from wide vertical openings. The paper is more a summary and a series of notes than a lengthy exercise in the subject.
This paper argues for the need to further develop an understanding of tourist experiences that more aggressively transcends traditional disciplinary boundaries, and that simultaneously re-centers tourist experiences as integral aspects of daily life. In order to do this, the text begins by problematizing the concept of the tourist. Whose experiences are we talking about, and in what ways do issues
Adherence to lifestyle modification and pharmacological treatment is of great importance in order to achieve maximum benefits of preventive measures after a cardiac event. Unfortunately, patients are neither adopting adequate lifestyle changes nor do they adhere to prescribed medication. Consequently, implementation of CHD guidelines is less than optimal in clinical practice. The general aim of th
OBJECTIVE: To determine whether the combined use of Lerner's morphologic score and color Doppler ultrasound examination results in better discrimination of benign and malignant adnexal masses than the use of Lerner's score alone or Doppler variables alone. DESIGN: One hundred and seventy-three consecutive women with a pelvic mass judged clinically to be of adnexal origin underwent preoperative ult
The Mn-derived electron paramagnetic resonance (EPR) multiline signal from the S0 state of the water-oxidizing complex is observable only in the presence methanol. In the present study, we have characterized the effect of methanol on the EPR signals from the S0 and S2 states as well as on the EPR Signal IIslow originating from the TyrosineDox radical. The amplitudes of the S0 and S2 multiline sign
The initial oxidation of Rh(100) has been studied using high resolution core level spectroscopy, low energy electron diffraction, surface x-ray diffraction, scanning tunneling microscopy, and density functional theory. We report a structural study of an oxygen induced structure displaying a c(8x2) periodicity at an oxygen pressure above 10(-5) mbar and using a sample temperature of 700 K. Our expe
BACKGROUND AND AIMS: Helicobacter pylori is the major causative agent in peptic ulcer disease and is strongly implicated in the development of gastric cancer. It has also been linked, less strongly, to cardiovascular disease. The mechanisms by which certain Strains of H pylon induce platelet aggregation through interactions with platelet glycoprotein 1b have been previously described. METHODS: In
An option of increasing the luminosity of the Large Hadron Collider (LHC) at CERN to 1035 cm-2 s-1 has been envisaged to extend the physics reach of the machine. An efficient tracking down to a few centimetres from the interaction point will be required to exploit the physics potential of the upgraded LHC. As a consequence, the semiconductor detectors close to the interaction region will receive s
Using laser-Doppler flowmetry during ventriculocisternal perfusion with inulin-[14C]carboxylic acid, choroid plexus blood flow (CPBF) and CSF production were measured simultaneously in rats during periods of 3 h. Blood flow and CSF production decreased only slightly during control experiments. The effect of vasoactive intestinal polypeptide (VIP) was studied at different concentrations of the pept
A well-known effect of increasing age is the gradual reduction of muscle function, and thus of performance in the activity of daily living. Recent research has shown that, even among the very elderly, exercise can improve not only strength and endurance, but also balance and mobility, thus reducing the risk of falls. The possibility of counteracting some of the age-related muscle changes has also
Problemen med alkali-kiselsyrareaktioner i Sverige ('AKRIS') är nya och började uppträda då ett cement med högre alkalihalt ersatte det tidigare lågalkalicementet som använts i södra Skåne, där betonggrus normalt innehåller alkalireaktiva korn av opalflinta och opalsandsten.Bara på 'fuktiga inomhuskonsruktioner', som har haft en speciell fukthistoria, har pop-outs uppkommit.
A comparison between the effect of low molecular weight heparin (LMWH) and unfragmented heparin (UH) on induction of osteoporosis was made in 60 rats treated with either UH (2 IU/g bw), LMWH in 2 doses (2 XaI U/g or 0.4 XaI U/g) or placebo (saline) for 34 days. Studied variables were: bone mineral mass in femora; fragility of humera; zinc and calcium levels in serum and bone ash and albumin in pla
Altered renal function is an essential component of the pathophysiological process in preeclampsia. The kidneys play a significant part in the turnover of most low molecular weight substances such as creatinine, urate and cystatin C. The present work was undertaken to investigate if the serum levels of these components are altered in characteristic ways in preeclampsia, and can be used to assist i
