Exception Handling in Recipe-Based Batch Control
The focus of this thesis is exception handling in recipe-based batch control. Exception handling is a critical element for achieving long-term success in batch production. It is reported to constitute 40-60 percent of the batch control design and implementation effort. Correct handling of exceptions is a key element in process safety, consistent product quality, and production cost minimization. T
Assessing the carbon balance of circumpolar Arctic tundra using remote sensing and process modeling
This paper reviews the current status of using remote sensing and process-based modeling approaches to assess the contemporary and future circumpolar carbon balance of Arctic tundra, including the exchange of both carbon dioxide and methane with the atmosphere. Analyses based on remote sensing approaches that use a 20-year data record of satellite data indicate that tundra is greening in the Arcti

Endovascular AAA exclusion: will stents with hooks and barbs prevent stent-graft migration?
PURPOSE: To investigate if stents with hooks and barbs will improve stent-graft fixation in the abdominal aorta. METHODS: Sixteen- to 24-mm-diameter Dacron grafts were deployed inside cadaveric aortas. The grafts were anchored by stents as in endovascular abdominal aortic aneurysm repair. One hundred thirty-seven stent-graft deployments were carried out with modified self-expanding Z-stents with (
ECG-based detection of body position changes in ischemia monitoring
The purpose of this gaper is to analyze and detect changes in body position (BPC) during electrocardiogram (ECG) recording. These changes are often manifested as shifts in the, electrical axis and may be misclassified as ischemic changes during. ambulatory monitoring. We investigate two ECG signal processing methods for detecting BPCs. Different schemes for feature extraction are used (spatial and
Bone mineral density assessed by quantitative ultrasound and dual energy X-ray absorptiometry. Normative data in Malmo, Sweden
We measured bone mineral density (BMD) in 128 men and 143 women, aged 22-90, by dual energy X-ray absorptiometry (DEXA) and quantitative ultrasound (QUS). We found reduced bone mineral density in relation to age as measured both by DEXA and QUS. There was a correlation between 0.28 and 0.52 in men and between 0.53 and 0.77 in women when comparing DEXA and QUS measurements. When including only pers
Low recurrence rate after deep calf-vein thrombosis with 6 weeks of oral anticoagulation
OBJECTIVES: To evaluate the recurrence rate after deep calf-vein thrombosis treated with 6 weeks of oral anticoagulation. DESIGN AND SUBJECTS: A 2 year follow-up of 126 consecutive patients admitted to the Department of Internal Medicine with venographically verified deep calf-vein thrombosis. RESULTS: One hundred and twenty-six patients were treated with warfarin for 6 weeks, 18 of them having ha

Comparison of the electronic structure of PPV and its derivative DIOXA-PPV
Electronic structure of two conjugated polymers, PPV and its derivative DIOXA-PPV, are studied by quantum-chemistry methods. Good agreement between the calculations and available experimental data validates the applied methods and enables us to draw conclusions about properties of excitons and polarons in these polymers. In particular, simultaneous use of different correlation plots in atomic site
Physical workload on neck and upper limb using two CAD applications.
The aim was to evaluate (1) the physical workload on neck and upper limb in computer-aided design (CAD) work; (2) the impact of two applications (PROFESSIONAL-CADAM and PRO/Engineering) and (3) two input devices (computer mouse and keyboard), as well as (4) sitting and standing work positions. Fifteen CAD operators were interviewed and examined physically. For nine subjects, the physical workload
Growth, morbidity and mortality after chickenpox infection in young children in Guinea-Bissau
OBJECTIVE: To examine whether chickenpox in children below 2 years of age is associated with post-infection changes in growth, morbidity or mortality. METHODS: An outbreak of chickenpox was investigated in Guinea-Bissau. An examination, interview and anthropometry were performed 6 months after the epidemic for a group of children and matched controls whose weight had been measured at the time of t
Improved prandial glucose control with lower risk of hypoglycemia with nateglinide than with glibenclamide in patients with maturity-onset diabetes of the young type 3
OBJECTIVE - To study the effect of the short-acting insulin secretagogue nateglinide in patients with maturity-onset diabetes of the young type 3 (MODY3), which is characterized by a defective insulin response to glucose and hypersensitivity to sulfonylureas. RESEARCH DESIGN AND METHODS - We compared the acute effect of nateglinide, glibenclamide, and placebo on prandial plasma glucose and serum i
A Symmetrization-Desymmetrization Procedure for Uniformly Good Approximation of Expectations Involving Arbitrary Sums of Generalized U-Statistics
Transient electromagnetic wave propagation in transverse periodic media
In this paper, a time-domain technique is used to analyze the wave propagation of electromagnetic pulses in media that are periodic in one spatial direction, perpendicular to the direction of propagation. The wave equation is reduced to a system of one-dimensional first order time dependent hyperbolic equations by a Fourier expansion in the transverse spatial direction and by utilizing a wave spli
Endothelial dysfunction after repeated Chlamydia pneumoniae infection in apolipoprotein E-knockout mice
BACKGROUND: Arterial relaxation is largely regulated by endothelial nitric oxide (NO). Its diminished activity has been associated with incipient atherosclerosis. We investigated the endothelium-dependent relaxation of aorta in apolipoprotein E-knockout (apoE-KO) mice exposed to single or repeated Chlamydia pneumoniae inoculation. METHODS AND RESULTS: Forty-eight apoE-KO mice, 8 weeks old, were in
The interaction of peakons and antipeakons
In this note we discuss some aspects of the peakon-antipeakon interaction for the Camassa-Holm equation.
Intermediate phases observed during decomposition of LiBH4
Lithium tetrahydridoboranate is among the materials with the highest hydrogen content and has great potential as a possible H-2-storage material, although, the release and uptake of H-2 is not fully understood. In this work, LiBH4 was studied by in situ synchrotron radiation powder X-ray diffraction (PXD) and solid state CP/MAS NNIR both at variable temperatures. This study revealed two new phases
Asbestos and cancer: An overview of current trends in Europe
This review assesses the contribution of occupational asbestos exposure to the occurrence of mesothelioma and lung cancer in Europe. Available information on national asbestos consumption, proportions of the population exposed, and exposure levels is summarized. Population-based studies from various European regions on occupational asbestos exposure, mesothelioma, and lung cancer are reviewed. Asb
