The 6Li(n,α) reaction cross-section is commonly used as a reference cross section. However, it is only considered a neutron standard up to 1MeV. For higher energies, there are discrepancies of several per cents between recent measurements and evaluated data files. In order to extend and establish 6Li(n,α) as a neutron standard above 1MeV these discrepancies must be resolved. Our measurement at the
Despite the efforts to reduce its water consumption, the food industry still requires large amounts of water. Membrane processes have established themselves in the food industry at the beginning of the water loop for preparation of the intake water and at the end water loop for recovery and final treatment of the water. The focus of this paper is on two application studies related to water recover
We discuss a new scenario for the formation of intermediate mass black holes (IMBHs) in dense star clusters. In this scenario, IMBHs are formed as a result of dynamical interactions of hard binaries containing a stellar-mass black hole (BH), with other stars and binaries. We discuss the necessary conditions to initiate the process of intermediate mass BH formation and the influence of an IMBH on t
Background: Myofibroblasts, proposed as being derived from circulating fibrocytes, are considered to be important cells in thickening of the basement membrane in patients with asthma. We have studied the correlation of tissue fibrocyte levels to basement membrane thickness and the presence of fibrocytes in bronchoalveolar lavage fluid (BALF) in steroid-naive patients with mild asthma and controls.
BACKGROUND: The value of CT at the time of diagnosis for patients with cutaneous head and neck melanoma clinically asymptomatic for metastatic disease is unclear. METHODS: A retrospective medical chart review was performed on 198 consecutive patients identified with primary T1b-T4b head and neck melanoma clinically asymptomatic for metastatic disease referred for sentinel lymph node biopsy proceduBACKGROUND: The value of CT at the time of diagnosis for patients with cutaneous head and neck melanoma clinically asymptomatic for metastatic disease is unclear.METHODS: A retrospective medical chart review was performed on 198 consecutive patients identified with primary T1b-T4b head and neck melanoma clinically asymptomatic for metastatic disease referred for sentinel lymph node biopsy procedur
This essay discusses the development of swords in the southern region of Sweden, Skåne. It attempts to locate the areas in Europe where the swords were first made and, in doing so, trace the communication routes by which people traveled. The essay deals with a period of a few hundred years, from the late eighth century to sometime around 1300. In that sense, it is therefore also a time study trac
A capacitive biosensor with polyclonal antibodies raised against human serum albumin (HSA) immobilized on a gold transducer has been developed for continuous measurement of HSA in the μM-range. A mathematical model has been refined to describe integral HSA-binding curves assuming that (i) binding is essentially irreversible under the conditions used, (ii) the signal is scaled as the number of non-
This Master’s Thesis is the result of the collaboration between The Technical Faculty of Lund University and TÜV NORD Sweden AB. Focus has been directed towards the nuclear industry where this thesis is one of several other Master’s Theses regarding the dynamic modeling of a swing check valve. It is necessary for the nuclear industry to be able to model flow transients which involve the dynamic b
The Taranta1 project, a collaboration between the MAX IV Institute1 and Square Kilometre Array (SKAO)2 within the Tango3 Collaboration, presents a web-based, no-code approach for creating graphical interfaces dedicated to monitoring and controlling Tango-based systems. Through an active development phase and close collaboration with the community, the software has seen the introduction of advanced
Dopaminergic (DA) neurons derived from human pluripotent stem cells (hPSCs) represent a renewable and available source of cells useful for understanding development, developing disease models, and stem-cell therapies for Parkinson's disease (PD). To assess the utility of stem cell cultures as an in vitro model system of human DA neurogenesis, we performed high-throughput transcriptional profiling
BACKGROUND: Post-traumatic syringomyelia (PTS) affects patients with chronic spinal cord injury (SCI) and is characterized by progressive deterioration of neurological symptoms. To improve surgical treatment, we studied the therapeutic effects of neuroepithelial-like stem cells (NESCs) derived from induced pluripotent stem cells (iPSCs) in a rat model of PTS. To facilitate clinical translation, we
The study presents a multi-proxy archive from hypersaline coastal Lake Chokrak in eastern Crimea, a steppe region which is particularly susceptible to moisture fluctuations. XRF, organic carbon and nitrogen, and palynological analyses are used to reconstruct the evolution of the lake and landscape development around it and to provide information about the driving forces behind those changes, such
This thesis consists of five papers concerned with the modeling of stochastic signals, as well as deterministic signals in stochastic noise, exhibiting different kinds of structure. This structure is manifested as the existence of finite-dimensional parameterizations, and/or in the geometry of the signals' spectral representations. The two first papers of the thesis, Papers A and B, consider the m
