An experimental technique with which to measure the fracture stress of fused curd grains, submerged in ultrafiltered milk permeate, has been developed and applied to curd grains of rennet-induced skim milk at pH 6.40 during the first 25 min of fusion. Effects of applied compressive stress within the range of 25-50 Pa, syneresis time, fusion time and tension loading rate were investigated. Fracture
Water-soluble hemicelluloses were extracted from spruce chips by heat-fractionation using microwave treatment. A screening of conditions (pH, temperature and residence time) was performed for the extraction of O-acetyl-galactoglucomannan (AcGGM). The yield and the average molecular weight of the extracted mannan were analysed using HPLC, size-exclusion chromatography (SEC) and mass-spectrometry. T
Field studies were conducted during three years to determine the vertical (height level) and horizontal (distance from stand edge) distribution of flying Neodiprion sertifer (Geoffroy) males in a non-outbreak population. Sticky traps baited with synthetic female pheromone (25, 35, 75-diprionyl acetate) were used in a mature stand of Scots pine (Pinus sylvestris L.) in Central Europe (southern Bohe
First meiotic division in females and males of Yponomeuta evonyrnellus (L.), Y. cagnagellus (Hiibner). Y. rnalinellus Zeller, Y. padellus (L), Y. rorellus (Hiibner) and Y. gigas Rebel was studied in the light microscope. In the heterogametic females the sex chromosomes were found to be associated in a sex chromosome trivalent. The sex chromosome trivalent, written AA
During whey powder production, the feed is subjected to several heat treatments which can cause lactosylation of proteins. In this study, lactosylation of whey proteins was evaluated in spray-dried powders before and after storage by varying the native protein fraction as well as the serum protein/lactose ratio in the powders. The lactosylation of native α-lactalbumin and β-lactoglobulin in the po
This thesis investigates the role of interior design elements, especially artwork, in way-searchers’ wayfinding and orientation in hospital environments. The thesis considers the way-searcher’s background and the impact of cultural belonging, occupation, memories, aesthetic preferences, and language, and the influence that such factors might have on the perception of the hospital environment and i
A phenomenological model for simulating photoplethys-mogram (PPG) during paroxysmal atrial fibrillation (AF) is proposed. A PPG pulse is modeled by combining a lognormal and two Gaussian waveforms. Continuous PPG signals are produced by placing and connecting individual pulses according to the RR interval pattern extracted from annotated ECG signals. This paper presents a practical application of
This paper will approach the topic “What does heritage change?” by looking at the perspectives and experiences of a special category of heritage-makers, namely so-called “transmitters of intangible cultural heritage” (feiwuzhi wenhua yichan chuancheng ren) in China. It will explore the processes of heritagization and will ask whether, and what, heritage status changes when it comes to these indivi
Iron is a one of the critical elements in our life, being the most common element on earth, forming most of the inner and outer earth’s core. In our bodies iron is required in small amounts for biological processes to be performed. It is recommended to eat food containing iron to avoid common health problems such as anemia. A slight increase or decrease in iron levels above or below normal in liviFriedreich’s ataxia (FRDA) is an autosomal recessive neurodegenerative disease caused by defeciency in frataxin, a highly conserved protein central to iron homeostasis in mirochondria. The function of frataxin is related to its capability to bind, store and deliver iron to different biochemical process such as iron-sulfur cluster assembly and heme biosynthesis. Most FRDA pateints have extended GAA
The efforts to develop a dopamine cell replacement therapy for Parkinson's disease have spanned over more than three decades. Based on almost 10 years of transplantation studies in animal models, the first patients receiving grafts of fetal-derived dopamine neuroblasts were operated in Lund in 1987. Over the following two decades, a total of 18 patients were transplanted and followed closely by ou
While research on the design of heterogeneous concurrent systems has a long and rich history, a unified design methodology and tool support has not emerged so far, and thus the creation of such systems remains a difficult, time-consuming and error-prone process. The absence of principled support for system evaluation and optimization at high abstraction levels makes the quality of the resulting im
Introduction Sweden, as many other high-income countries, has adopted guidelines to offer induction of labour at 41+0 gestational weeks to decrease the risk for perinatal death. As more than 20% of the pregnant population reach this gestational age, and along with other contributing factors, induction rates have increased up to 30% in many countries. Both women and care providers have raised the q
Flowing water impacts bridges over rivers primarily in two ways: (1) hydrodynamic forces that directly impact the structure and (2) scouring at piers and abutments, including contraction scour. The design prin-ciples for bridges in Sweden, including both impacting forces and local scour, are relatively simplistic. The purpose of this paper is to examine the impact of extreme river flows on bridges
Purpose: This study aims to explore the experiences of care, psychosocial support, and psychosocial wellbeing among patients treated for COVID-19 in intensive care 12 to 18 months after discharge. Methods: This study used a qualitative approach with a descriptive design. Semi-structured interviews were performed with 20 adult patients treated for COVID-19 12 to 18 months after being discharged fro
By connecting an uncertain present to a potential future, predictions and other forms of projected futures construct meaningful contexts on which actors can lean when seeking to act in the face of uncertainty. This article outlines the background and careers of many, and often contradicting, futures that informed the collective work to define and represent Covid-19 in Sweden during the first half
Background The colonisation of Australia led to a lot of suffering and sorrow for an uncountable amount of Indigenous people. Due to the forced change of lifestyle and diet during and after the colonisation, conditions like obesity and type 2 diabetes became commonly occurring. Still today there is a higher burden of these conditions, but also of depression and anxiety, in this group of people. Fu
The purpose of this study is to examine types of challenges during the implementation of BPM regarding the set and use of performance indicators from a theoretical and practical perspective. Consequently, this thesis generates an understanding by illuminating reasons behind the previously found challenges. Hereby, this case study has followed a qualitative, abductive research strategy. The used pr
