Popular Abstract in Swedish Jonstråleanalys är ett fält inom tillämpad fysik vars utövare sysselsätter sig med bestrålning av olika föremål med joniserande strålning från partikelacceleratorer. Fysiker och kemister observerade i början av nittonhundratalet att joniserande strålning såsom alfapartiklar från radioaktiva källor ger upphov till olika sorters strålning när den växelverkar med materiThe overall goal of this thesis is to test new detector technologies and data acquisition systems, for use in Ion Beam Analysis IBA. This is intended to complement the existing setup, which is routinely used at Lund Ion beam Analysis Facility LIBAF. Proton induced X-ray emission is a well-known method for trace element analysis of heavier elements, but trace element analysis of elements below alum

The borderless world is providing new opportunities for conducting business, both within Europe and between continents. Sustainable competition will be harder to attain and competition will become fiercer, day-by-day. The Austrian school of strategy emphasizes change, continuous innovation, and entrepreneurial discovery as sources of supernormal profits. An important assumption is that these super

Popular Abstract in Swedish Hur kan man skapa en tredimensionell modell av ett objekt eller en plats från tvådimensionella bilder? Det är den centrala frågan i den här avhandlingen och en viktig fråga i datorseende generellt. Normalt delar man upp problemet i en serie basproblem. Ett basproblem kan till exempel vara att skatta kamerans rörelse mellan två bilder eller kamerapositionen för en ny bilThis thesis is concerned with the geometrical parts of computer vision, or more precisely, with the three-dimensional geometry. The overall aim is to extract geometric information from a set of images. Most methods for estimating the geometry of multiple views rely on the existence of robust solvers for a set of basic problems. Such a basic problem can be estimating the relative orientation of two

We report on a quantum dots-in-a-well infrared photodetector (DWELL QDIP) grown by metal organic vapor phase epitaxy. The DWELL QDIP consisted of ten stacked InAs/In0.15Ga0.85As/GaAs QD layers embedded between n-doped contact layers. The density of the QDs was about 9 x 1010 cm-2 per QD layer. The energy level structure of the DWELL was revealed by optical measurements of interband transitions, an

Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive malignancy. Here we show that shotgun and targeted protein sequencing can be used to identify potential prognostic biomarkers in formalin-fixed paraffin-embedded specimens from 9 patients with PDAC with "short" survival (< 12 months) and 10 patients with "long" survival ( > 45 months) undergoing surgical resection. A total of 24 and 14

Resilience is a debated concept with numerous definitions. If focusing on describing a community under stress of a particular disruptive event, its more traditional etymological meaning of ability to spring back after deformation, or its more applied meaning of ability to cope with and recover from the event, are sufficient. However, if focusing on building and maintaining resilient communities ov

To increase the understanding of wind turbine noise on sleep, human physiological reactions need to be studied in a controlled laboratory setting. The paper presents an outdoor-indoor noise level difference as a function of frequency, applicable to creating wind turbine indoor sounds with the outdoor sounds as input. For this, a combination of measurement data and modeling results has been used. T

The chitosan and gelatine are commonly used biopolymers for the tissue engineering applications. In the previous methods for the cryogels synthesis, multistep preparation methods using toxic cross-linking agents such as glutaraldehyde are reported. Here, we present a two-step preparation method of gelatin macroporous cryogels and one-step preparation method of chitosan or gelatin cryogels. The phy

To address global sustainability challenges, major investments are required in sustainable businesses that deliver triple bottom line results. Although interest in sustainable businesses is on the rise, these businesses are not yet widespread. Venture capital investment has a key role to play in the development of sustainable start-ups. The research area of 'sustainable' venture capital is still e

BACKGROUND: Refractory neuropathic inguinodynia following inguinal herniorrhaphy is a common and debilitating complication. This prospective study evaluated long-term outcomes associated with laparoscopic retroperitoneal triple neurectomy.METHODS: Sixty-two consecutive patients (51 male; mean age, 47); all failing pain management; prior reoperation in 35, prior neurectomy in 26; average follow-up

The design of antennas for compact multiple-input multiple-output (MIMO) terminals is a challenging feat, due to the space constraint and the physical structure of the terminal. The space constraint forces the antennas to be closely spaced, which degrades MIMO performance due to high signal correlation and low antenna efficiency. Moreover, the terminals are equipped with ground planes which furthe

The purpose of this paper is to introduce the concept coworkers’ communicative responsibility taking and to test which factors might influence coworkers’ tendency to take communicative responsibility. The study is split into two phases where on exploratory phase consisted of an exploratory factor analysis on 2244 with the aim to find specific latent factors to test in the confirmatory phase. The c

The amyloid β-protein (Aβ) is believed to play a central role in Alzheimer’s disease (AD) pathogenesis and there is great interest in understanding the process of Aβ aggregation, its underlying mechanism and the species generated during aggregation and their biological activity. Although Aβ has been studied for more than 30 years, analysis of its aggregation has been hampered by structural and che

Abstract: Two new salicylaldiminato-copper(II) complexes, [Cu(L1)2] (1) and [Cu(L2)2] (2) (where HL1= 4 -tert-Butyl-2-[(thiophen-2-ylmethylimino)-methyl]-phenol and HL2= 2 , 4 -Di-tert-butyl-6-[(thiophen-2-ylmethylimino)-methyl]-phenol), endowed with a pendant thiophenyl moiety, were synthesized and characterized using standard spectroscopic techniques (FT-IR, UV-Vis, MS) and elemental analysis.
