Seven Campylobacter jejuni strains were characterised by a lectin typing assay. The typing system was based on a quartz crystal microbalance technique (QCM) with four commercially available lectins (wheat germ agglutinin, Maackia amurensis lectin, Lens culinaris agglutinin, and Concanavalin A), which were chosen for their differing carbohydrate specificities. Initially, the gold surfaces of the qu
Nonlinear optical effects can be used for spectral broadening, which the basis of the field of post-compression of laser pulses. When the intensity of light becomes high enough the refractive index becomes intensity dependent, and as the intensity often varies both with position and time so does the refractive index. The consequence of the position dependence is self focusing, an often unfavorable
27 maj 2025 13:00 till 17:00 | Föreläsning, Konsert Välkommen till en eftermiddag som utmanar traditionella ledarskapsmodeller och tar dig in i ett mer kreativt, insiktsfullt och dynamiskt universum. Här skärskådar vi vad verkligt ledarskap innebär – bortom manualer och standardiserade metoder – och utforskar hur konst, kultur och forskning formar framtidens ledare. Eventet hålls på engelska.

Title: Identification and suggestions of emerging technologies for a smart warehouse Authors: Xinchuan Li, Monish Ashok Kumar Background description: The warehouse is a crucial point and one of the most vital logistics and supply chain management links. Warehouses are built to smooth the supply chain and can be divided into different classifications. The importance of warehouses has increased a lo
Mild reductive catalytic depolymerization (MRCD) of lignin offers a sustainable route to produce functionalized aromatic compounds. However, the economic viability is hindered by the need for expensive palladium (Pd) catalysts and the limited exploration of continuous flow reactors (CFRs), which are essential to achieve an adequate production scale. This study examines the impact of partial replac
Popular Abstract in Swedish p-tert-Butylfenol-formaldehydharts (PTBP-F-R) är ett bindemedel som används i vissa limmer och målarfärger. Det har använts sedan 1950-talet och redan från denna tid finns rapporter om allergier. PTBP-F-R ingår i den internationella standardserien av kontaktallergen. Råvaror för framställning av hartset är p-tert-butylfenol och formaldehyd. Det färdiga hartset består avp-tert-Butylphenol-formaldehyde resin (PTBP-F-R) is used as a binder in many adhesive formulations and it consists of a complex mixture of substances, most of which are unknown. The resin has been reported to cause allergic contact dermatitis since the 1950s. The aim of the study was to investigate allergens in p-tert-butylphenol-formaldehyde resin (PTBP-F-R) and to isolate and identify sensitizer
BACKGROUND: Family history is an important risk factor for deep venous thrombosis. However, few studies have determined the importance of family history of pulmonary embolism (PE). OBJECTIVE: This nationwide study aimed to determine the familial risks of fatal and hospitalized PE. METHODS: The Swedish Multi-Generation Register for subjects aged 0 to 76years old born since 1932 were linked to t
Environmental research infrastructures are often built on a large number of distributed observational or experimental sites, run by hundreds of scientists and technicians, financially supported and administrated by a large number of institutions. It becomes very important to acknowledge the data sources and their providers. There is also a strong need for common data citation tracking systems that
Discussion and debate regarding decision-making that is 'in the best interest of the child' and that also considers the child's voice in these decisions have increased in recent years. A study was undertaken to identify everyday situations in medical and nursing care in which children had been allowed to have a voice or been denied the right. Twenty-six hospitalized children, ages 6 to 17 years, a
Differential absorption lidar (DIAL) measurements are usually made on single compounds by alternately switching the wavelength between on and off a resonance line. The selection of more than two wavelengths is a mathematical necessity for simultaneous measurement of multiple species or for resolving interference effects between a compound of interest and a background gas such as water vapour or ca
A coupled lake-catchment model was developed to examine the controls on lake-level changes in currently overflowing lakes during Holocene. The lake energy-balance is simulated as the one-dimensional vertical heat transfer by eddy diffusion and convective mixing. The accumulation and ablation of lake ice, and snow cover on the ice, is simulated thermodynamically. The lake water-balance is given by
A correlation spectroscopy (COSPEC) based on a multi-wavelength fiber laser is first proposed for the detection of gas concentration. The lasing wavelengths are selected to match several characteristic absorption peaks of the gas under test, and the gas concentration is easily measured by correlating it with the reference gas. The present method is immune from the instability of the light source a
Results are reported for thermophoretic deposition of soot particles on resistivity sensors as a monitoring technique for diesel exhaust particles with the potential of improved detection limit and sensitivity. Soot with similar characteristics as from diesel exhausts was generated by a propane flame and diluted in stages. The soot in a gas flow at 240–270C∘ was collected on an interdigitated elec
Near field Inverse Synthetic Aperture Radar Cross Section (RCS) measurements are used in this study to obtain geometrically correct images of objects placed on a turntable. The images of the targets are processed using a method common in the compressive sensing field, Basis Pursuit Denoise. A near field model based on isotropic point scatterers is set up. The target model is naturally sparse and t
Knowledge on the absorption rate of CO2 in absorption systems is essential for accurate equipment design. This work is focused on determining the rate of absorption for novel absorption systems using a wetted wall column. This is a widely used method for determining the absorption flux of carbon dioxide in amine solutions. Two absorption systems were investigated, namely aqueous solutions of monoe
The purpose of this paper is to briefly discuss the rationale for using Student Response Systems (SRS) and to share our experience of using this teaching technology in a training session. Our experiences support existing pedagogical research and show that SRS can be used to transform traditionally passive lecture-based classes into stimulating, active learning environments. Students demonstrate be
