Laminar burning velocities of methylcyclohexane + air flames were determined using the heat flux method at atmospheric pressure and initial temperatures of 298–400 K. The measurements were performed on two experimental setups at Lund University and Samara National Research University. Our results obtained at the same initial temperatures are in good agreement. Consistency of the measurements perfo
Doktorsavhandling i Gamla testamentets exegetik. I avhandlingen kartläggs vilka tolkningsstrategier som är tongivande i modern kommentarlitteratur av Psaltarens s.k. 'förbannelsepsalmer,' dvs. bibeltexter som vanligen utelämnas i modernt gudstjänstliv av innehållsliga skäl då de uttrycker den bedjandes önskan om hämnd och/eller våld gentemot fiender. En översikt av den exegetiska diskursen, så som
Purpose: One of the main limitations of absorption‐based x‐ray imaging of biomedical specimen is the weak soft‐tissue contrast. This limitation can be addressed by phase‐sensitive imaging methods facilitating considerably improved density resolution. During the last decades various approaches have been investigated ‐ amongst them grating‐based interferometric methods with laboratory x‐ray sources.
Background: Swedish Emergency Departments (EDs) see 2.6 million visits annually. Sweden has a strong tradition of health care databases, but information on patients’ pathways to the ED is not documented in any registry. The aim of this study was to provide a national overview of pathways, degree of medical acuteness according to triage, chief complaints, and hospital admission rates for adult pati
The recent introduction of entry inhibitors in the clinic as components of antiretroviral treatment has heightened the interest in coreceptor use of human immunodeficiency virus type 1 (HIV-1). Viruses using CCR5 as coreceptor (R5 viruses) are generally present over the entire course of infection whereas viruses using the CXCR4 coreceptor (R5X4/X4 viruses) emerge in about 50% of infected individua
Background: Thiopentone elimination has been described using Michaelis-Menten pharmacokinetics in adults after prolonged infusion or overdose, but there are few reports of elimination in neonates. Methods: Time-concentration profiles for neonates (n=37) given single-dose thiopentone were examined using both first-order (constant clearance) and mixed-order (Michaelis-Menten) elimination processes u
Paper 1The problem in which a flexible structure interacts with an acoustic fluid is analysed by use of the finite element method. With increasing complexity of the geometry and when increasing the frequency limit is of interest, the number of degrees of freedom needed to describe the system becomes very large. To reduce the coupled system, modal analysis is performed in the structural and in the
A fedbatch process shows exponential growth under ideal conditions. To obtain good substrate concentration control it is necessary that the regulator can track an exponentially growing feed demand, and standard PI-control has to be supplemented with an estimated basic dosage to get reasonable control. However, an exponentially growing concentration error is impossible to avoid. An I-term could be
Popular Abstract in Swedish Nanoteknik och nanotrådar omnämns ofta media idag, men vad är egentligen en nanotråd, och vad kan den användas till? Dagens datorer, lysdioder och solceller är till stor del beroende av halvledare. En halvledare är ett kristallint material där man enkelt kan ändra ledningsförmågan. Man kan dels bestämma ledningsförmågan när materialet tillverkas genom att tillföra ytterThis thesis investigates novel electrical nanowire characterization tools and devices. Conventional characterization methods, long available to bulk semiconductor samples, have been adapted and transferred to the nanowire geometry. The first part of the thesis describes the development of Hall effect measurements, an entirely new characterization tool for nanowires. It is shown that Hall effect me
Dominant policy approaches have failed to generate action at anywhere near the rate, scale or depth needed to avert climate change and environmental disaster. In particular, they fail to address the need for a fundamental cultural transformation, which involves a collective shift in mindsets (values, beliefs, worldviews and associated inner human capacities). Whilst scholars and practitioners are
Molecularly imprinted polymers (MIPs) have now become one of the most remarkable materials in the field of molecular recognition. Although many efforts have been made to study the process and mechanism of molecular imprinting, it has not been possible to monitor the interactions between the template and the growing polymer chains under real-time experimental conditions. The behavior of the templat
Levinson (2003) provides evidence that distinct cultures display distinct spatial references that, as a consequence, impacts the linguistic encoding of spatial notions. This linguistic variation has fostered the interest of understanding the spatial domains responsible for the linguistic encoding of spatial information. According to Levinson and Wilkins (2006, p. 2), these domains consist in: the
3D bioprinting has the potential to provide a unified framework for the manufacturing of tissue models for biomedical research, including drug discovery, disease modeling, and regenerative medicine. However, it remains challenging to 3D print replicas of human tissues that have accurate cell types, cellular densities, extracellular matrix compositions, and that can be assayed in a minimally invasi
Background: Abiraterone acetate (AA) is an androgen biosynthesis inhibitor shown to prolong life in patients with castration-resistant prostate cancer (CRPC) already treated with chemotherapy. AA treatment results in dramatic declines in prostate-specific antigen (PSA) in some patients and no declines in others, suggesting the presence of molecular determinants of sensitivity in tumors. Objective:
Background and purpose — Obesity has been associated with inferior outcomes after laminectomy due to central lumbar spinal stenosis (CLSS); we evaluated whether this occurs in surgery on national bases. Patients and methods — We retrieved pre-and 1-year postoperative data from the National Swedish Quality Registry for Spine Surgery regarding patients aged ≥ 50 with laminectomy due to CLSS in 2005–
