We review the history of floristic studies of the parish of Stenbrohult, southern Sweden, where Carl Linnaeus was born in 1707 and spent his summers until 1728. Unfortunately, Carl Linnaeus never made a list of the wild vascular plants at his birthplace, although he mentioned at least 64 species from the parish of Stenbrohult in various manuscripts and books. However, he said that Stenbrohult was
OBJECTIVE—This study examines whether autonomic nerve autoantibodies (ANabs) are associated with development of autonomic neuropathy using a prospective study design. RESEARCH DESIGN AND METHODS—A group of type 1 diabetic patients were followed prospectively with regard to autonomic nerve function on four occasions. At the third examination, 41 patients were tested for ANabs (complement-fixing au
The main concern of this thesis is to experimentally investigate the turbulent flow and heat transfer in a ribbed channel. Such flows are encountered in many engineering applications, e.g., gas turbine cooling. In order to highlight the physical mechanism of flow separation, only one wall of the channel is fitted with periodic ribs. The inter-rib spacing is set such that the reattachment is allowe
Objective: To determine the nature and extent of undersupply and the economic consequences of oversupply of medication among non-adherent patients. Methods: This study used copies of repeat prescriptions (=multiple dispensations), collected during 1 week in 2002 at 16 Swedish community pharmacies. For patients with a refill adherence below 80%, treatment gaps were defined as the number of days the
Objectives: In this work we studied the temporal evolution of changes in the electrocardiogram (ECG) as a consequence of the induced ischemia during prolonged coronary angioplasty, comparing the time course of indexes reflecting depolarization and those reflecting repolarization. Methods: We considered both local (measured at specific points of the ECG) and global (obtained from the Karhunen-Loeve
The AURKA oncogene is associated with abnormal chromosome segregation and aneuploidy and predisposition to cancer. Amplification of AURKA has been detected at higher frequency in tumors from BRCA1 and BRCA2 mutation carriers than in sporadic breast tumors, suggesting that overexpression of AURKA and inactivation of BRCA1 and BRCA2 cooperate during tumor development and progression. The F31I polymo
Volatiles from Ips duplicatus male hindgut extracts and aeration samples of spruce logs colonized by the virgin males were analyzed by coupled gas chromatography-mass spectrometry (GC-MS), coupled gas chromatography-electroantennographic detection (GC-EAD), and field trapping bioassays in Inner Mongolia, China. GC-MS analyses showed that males from nuptial chambers (for reproduction) produced hind
A miniaturized on-column digestion system constructed for the sequential analysis of semi-purified protein analytes is presented. By utilizing fused silica capillary (diameter 150 mu m) packed with a zone of trypsin-modified Eupergit C beads and a second zone of reversed-phase C18 material, a linear column set-up was constructed. The protein analytes (pmol amounts) were first digested in the 600 n
Six pigs were used to study whether the collection of shed blood by means of surgical compresses instead of suction traumatizes such blood. In an in vivo part of the study, the whole blood volume of the pigs was retransfused after treatment with citrated compresses, and in an in vitro part the blood was treated extensively with compresses and analyzed. All animals survived, with a minor fall in he
The charged particle production in ultra-relativistic nucleus-nucleus collisions in the energy range 4-200 A GeV has been studied. Two different experimental techniques have been utilized: nuclear emulsions and Multi-Step Avalanche Chambers. Four large Multi-Step Avalanche Chambers with optical read-out were included in the experiment WA93 and were used to reconstruct the tracks and determine the
This paper investigates the use of data-adaptive spectral estimation techniques for blood velocity estimation in medical ultrasound. Current commercial systems are based on the averaged periodogram, which requires a large observation window to give sufficient spectral resolution. Herein, we propose a novel data-adaptive method to form the blood velocity spectral estimate. The method is evaluated u
Methods of VUV electron beam ion trap (EBIT) spectroscopy are applied to the study of Pm-like tungsten (W13+). These data show that theory appears well capable of dealing with these multi-electron (61) ions, at least for high ionization stages. A comparison of other spectroscopic methods applied to the study of other ions of the Pm I sequence is also given, and finally a search for the Pm-like W l
OBJECTIVE - we sought to study the frequency of P-cell-specific autoantibody markers in women with gestational diabetes mellitus (GDM) and to follow these women to estimate the risk of later development of type I diabetes. RESEARCH DESIGN AND METHODS - Of 385 pregnant women with GDM during 1995-2005 in the district of Lund, 24 (6%) women were found positive for at least one of the following: islet
A novel insertion device for electron storage rings, called the MAX-Wiggler [Nucl. Instr. and Meth. A 467-468 (2001) 118], has been constructed at MAX-lab. The MAX-Wiggler is a cold bore superconducting wiggler magnet with 47,3.5 T poles and a period length of 61 mm. It is designed for the production of X-rays at the 1.5 GeV electron storage ring MAX-II [Nucl. Instr. and Meth. A 343 (1994) 644] at
