Laser-induced Rayleigh scattering is commonly employed for two-dimensional temperature measurements and offers benefits such as high accuracy, easily interpreted data and low experimental complexity. Yet the approach suffers from an interference often referred to as stray light, an umbrella term used for all spurious light being detected. As Rayleigh scattering is an elastic scattering phenomenon,
Allochthonous arthropods can sustain a local food web on seemingly barren land, but are nevertheless often neglected in studies of community assembly. In the present study, we investigated primary food web assembly on nunataks (ice-free areas) in a retreating glacier in Iceland. Nunataks enable studies that take into account both the temporal factor of the assembly and the influx of allochthonous
Microchip-based free flow acoustophoresis (FFA) in combination with two-dimensional cell prefocusing enables concurrent multiple target outlet fractionation of leukocytes into subpopulations (lymphocytes, monocytes, and granulocytes); we report on this method here. We also observed significantly increased accuracy in size-based fractionation of microbeads as compared to previously presented FFA mu
Fjärilen utvecklas genom en process som kallas metamorfos. Termen används också för att beskriva allmän omvandling eller förändring. En ny fas där något lämnas kvar. Jacob Kirkegaard - Metamorfos (2021) Metamorfors är ett soundtrack som använder ljudinspelningar av fjärilsvingar kombinerat med namn på utdöda fjärilsarter, viskade på latin. Ljudinspelningarna av fjärilsvingar spelades in i Lund i s

Men's violence against women is a major global problem. Pornography often depicts humiliation and violence against women. Moreover, it becomes problematic to work for an equal society when children have free access to pornography online. Therefore, the aim of the study is to investigate how employees in Swedish healthcare and aid organizations perceive the relationship between online pornograp
Denna uppsats undersöker ifall marknadsföringsmetoden Pay What You Want (PWYW) har en starkare positiv påverkan på en konsuments attityd gentemot en produkt i förhållande till gratisprover (FREE). Detta undersöktes på studenter i Lunds Universitet med ett implicit test, SC-IAT. Medan FREE ger bort produkten utan extra kostnad tillåter PWYW konsumenten friheten att köpa en produkt till vilket pris
A generic protocol for the creation of material-mediated self-assembled patterns of streptavidin, defined solely by patterns of gold and SiO2, is presented. Protein-adsorption resistance of selected regions was obtained by material-specific adsorption of thiol-modified poly(ethylene)glycol (thiol-PEG) on gold followed by adsorption of poly-L-lysine (PLL) modified PEG (PLL-g-PEG) on SiO2. Selective
OBJECTIVE: The study was designed to investigate the prevalence of celiac disease (CD) among 2.5-year-old children in a Swedish urban population with a high incidence of CD.MATERIAL AND METHODS: Six hundred ninety apparently healthy children, born in the 12-month period of July 1992 through June 1993, were screened for immunoglobulin A (IgA) antigliadin antibodies and IgA antiendomysium antibodies
Cyclic chiral lactide is the monomer chemical for polymerization of high molecular weight polylactic acid (PLA). The synthesis of cyclic l-lactide starts from poly-condensation of l-lactic acid to a low molecular weight prepolymer and then depolymerized to cyclic l-lactide. Lignocellulose biomass is the most promising carbohydrate feedstock for lactic acid production, but the synthesis of cyclic l
Optical wireless networks realized by means of gigabit optical wireless communication (OWC) systems are becoming, in a variety of applications, an important alternative, or a complementary solution, to their fiber-based counterparts. However, performance of the OWC systems can be considerably degraded in periods of unfavorable weather conditions, such as heavy fog, which temporarily reduce the eff
Fetal hemoglobin (HbF) has been developed into an important alternative protein for oxygen therapeutics. Such applications require extensive amounts of proteins, which only can be achieved via recombinant means. However, the expression of vertebrate hemoglobins in heterologous hosts is far from trivial. There are several issues that need to be dealt with. These include, among others, the solubilit
Critical raw materials (CRM) are extensively used in tools for metal cutting, such as in cemented carbide tools (cobalt and tungsten), because they provide desired characteristics of high fracture toughness and wear resistance. Both academia and industry are examining CRM-free material alternatives, such as tools based on polycrystalline diamond (PCD) or ceramic materials. These materials are gene
Background: Uveal melanoma is the most common primary intraocular malignancy in adults. Despite successful control of the primary tumor, metastatic disease will ultimately develop in approximately 50% of patients, with the liver being the most common site for metastases. The median survival for patients with liver metastases is between 6 and 12 months, and no treatment has in randomized trials eve
Background: Knowledge regarding the health-related quality of life (HRQoL) of children with celiac disease remains limited and inconclusive. We investigated the HRQoL of three groups of 12-year-olds with: i) undetected celiac disease ii) clinically diagnosed celiac disease, and iii) without celiac disease. Methods: A school-based cross-sectional multicenter screening study invited 18 325 children,
Protein aggregation can lead to major disturbances of cellular processes and is associated with several diseases. We report kinetic and equilibrium data by ThT fluorescence and enzyme-linked immunosorbent assay of sufficient quality and reproducibility to form a basis for mechanistic understanding of amyloid beta-peptide (A beta) fibril formation. Starting from monomeric peptide in a pure buffer s
The purpose of this essay is to examine how Nepal has implemented article 28 of the UN Convention on the Rights of the Child (CRC). The essay focuses on subdivision 1(a) in the article which establishes that all States Parties shall make primary education compulsory and free to all children within their country. Through the ratification of the CRC the Government of Nepal is under the obligation to
The main goal of this thesis is to initiate a set of experiments on high-order harmonic generation (HHG) in hollow core waveguides and to verify a higher conversion efficiency of HHG in waveguides compared to classical HHG schemes. High harmonics are in this context electromagnetic waves generated by focusing laser light into a dilute noble gas. The frequency of the thereby generated waves is q t
