This study investigated the longitudinal impact of methods for the drying off of cows with and without dry cow therapy (DCT) on the microbiota and resistome profile in colostrum and milk samples from cows. Three groups of healthy dairy cows (n = 24) with different antibiotic treatments during DCT were studied. Colostrum and milk samples from Month 0 (M0), 2 (M2), 4 (M4) and 6 (M6) were analysed us

High-sensitivity cardiac troponin assays have become the gold standard for diagnosing acute and chronic myocardial injury. The detection of troponin levels beyond the 99th percentile is included in the fourth universal definition of myocardial infarction, specifically recommending the use of sex-specific thresholds. Measurable concentrations below the proposed diagnostic thresholds have been shown

A strategy for control of substrate feed rate in fed-batch fermentations is presented. The main idea is to make pulses in the feed rate and to evaluate the response in the dissolved oxygen signal. This gives an indirect measurement of the substrate demand that is used for feedback control of the feed rate. Experimental data is used to develop a model of a fermentation process. The model is used to

This paper presents an investigation concerning the introduction of Extreme Programming (XP) in software development organisations. More specifically the concept of using a decision support method known as the Analytical Hierarchy Process (AHP) is evaluated by a group of students and a group of developers and the outcome is compared to experiences from an XP case study. The results provide an indi

This thesis investigation examines how understandings of risk are constructed in decisions of foreign investments in infrastructure projects in low and middle income countries, using the sustainability Impact Accelerator at the International Council of Swedish industry as a case study. Drawing on constructivist theory and risk management frameworks, it combines a qualitative document analysis of I

Denna studie har som syfte att undersöka hur Generation Y, en demografisk grupp som kännetecknas av miljöomtanke, teknologianvändning och resande betraktar den avancerade och multisensoriska kommunikationsformen Virtual Reality (VR) ur ett perspektiv av resande och hållbarhet. Målet är att förstå vilka faktorer som påverkar Generation Y att acceptera och använda VR för resande, samt att undersöka The purpose of this study is to examine how Generation Y, a cohort characterized by environmental care, technology utilization, and traveling, perceives the advanced mode of multisensory communication Virtual Reality (VR) from a perspective of traveling and environmental sustainability. The aim is to understand what important factors and drivers exist for Generation Y to accept and use VR-travelin

Fallskydd och multiplaner i Lomma släpper ut mikroplaster i Höje å! Ungefär var tionde lekplats i Lomma har en gummibaserad yta som släpper ifrån sig mikroplast. Vid en noggrannare undersökning av en skolgård upptäcktes att mikroplaster därifrån hamnat i ett närliggande vattendrag, Höje å, via dagvattenrören. Mikroplaster är ett problem som fått allt större uppmärksamhet den senaste tiden. FiskarMicroplastics have detrimental effects in marine, fresh water and terrestrial environments and is a pollution of growing concern worldwide. Microplastics originates from many different sources, e.g. from rubber granulates used in artificial turfs. In a recent study, artificial turfs (football fields) were identified as the second largest source of microplastics in Sweden (tyre wear being the large

The world as we know it today has evolved to be a very connected space, where not only ICT’s (information & communication technologies) have made it easy to interact with individuals around the globe at any time, but also developments in air travel allow to reach ever more distant destinations. Many go as far as describing the world as shrinking or small; it seems that at least it feels smalle

This essay had tested for the significant influence of USD index and Euro index on Gold market traded in Dollar and Euro. The results show that the mean return of Gold in both markets is affected by the USD index as well as Euro index. However the variance in each market is only significantly affected by the currency that the market is being traded. Applying APGARCH shows that Gold market variance

Attractive interactions between like-charged aggregates (macromolecules, colloidal particles, or micelles) in solution due to electrostatic correlation effects are revisited. The associated phenomenon of phase separation in a colloidal solution of highly charged particles is directly observed in Monte Carlo simulations. We start with a simple, yet instructive, description of polarization effects i

In this paper the machinery of Hybrid Logic and the logic of public announcements are merged. In order to bring the two logics together properly the underlying hybrid logic has been changed such that nominals only partially denote states. The hybrid logic contains nominals, satisfaction operators, the downarrow binder as well as the global modality. Following this, an axiom system for the Hybrid P

Biochemical signaling is mediated by complexes between macromolecular receptors and their ligands, with the duration of the signal being directly related to the lifetime of the ligand-receptor complex. In the field of drug design, the recognition that drug efficacy in vivo depends on the lifetime of the drug-protein complex has spawned the concept of designing drugs with particular binding kinetic

Among the numerous point vapor sources, microsecond-pulsed spark ablation at atmospheric pressure is a versatile and environmentally friendly method for producing ultrapure inorganic nanoparticles ranging from singlets having sizes smaller than 1 nm to larger agglomerated structures. Due to its fast quenching and extremely high supersaturation, coagulational growth already begins at the atomic sca

One of the most promising and critical application of vehicular ad hoc networks (VANETs) is improvement of the road traffic safety. Currently there is a growing belief that putting an 802.11-like radio into road vehicles could help the drivers to travel more safely. Although research in this field is in preliminary stage, some simple implementations are quite promising; to the best of our knowledg

Purpose - Aims to present general concepts and framework for increasing the flexibility in robotic arc welding with respect to use of sensors and small series production. Design/methodology/approach - Presents a conceptual model with a framework that integrates existing tools and needed developments and research to increase the usefulness of sensors in robotic arc welding. The conceptual model is

This paper addresses the problems associated with ambitious greenhouse gas (GHG) emission cut-off targets set for cities in recent years. Even though many cities have adopted an active approach to sustainability issues and climate change mitigation, they often lack appropriate and effective tools for achieving the cut-off targets. The primary purpose of this paper is to demonstrate the utilisation
