The homogeneous charge compression ignition ( HCCI) combustion engine principle lacks direct ignition timing control, instead the auto-ignition depends on the operating condition. Since auto-ignition of a homogeneous mixture is very sensitive to operating conditions, fast combustion phasing control is necessary for reliable operation. For this paper, a six-cylinder heavy-duty HCCI engine was contr

Pore formation and pore closure in poly(D,L-lactide-co-glycolide)-based drug delivery systems are two important processes as they control the release of the encapsulated drug. The phenomenon pore closure was investigated by studying the effects of the pH and the temperature of the release medium, and the properties of the polymer. Poly(D,L-lactide-co-glycolide) (PLG) films were subjected to a pore

We report on multiblock copolymers consisting of highly sulfonated hydrophilic poly(arylene sulfone) (SPAS) blocks combined with hydrophobic poly(arylene ether sulfone) (PAES) blocks. Dithiol-terminated precursor blocks of sulfonated poly(arylene thioether sulfone) (SPATS) were first prepared via polycondensations involving a novel tetrasulfonated dichlorotetraphenyldisulfone monomer, followed by

The relation between supraphysiologic circulating testosterone levels and prostatic diseases is unclear and difficult to study in men. Animal models may be advantageous. Based on a pilot study, testosterone enantate 50 mg (n=12) or 25 mg (n=12) was administered to guinea-pigs intramuscularly every 3 weeks, for either 7 or 14 months. The histopathology of the prostate was described. Epithelial hype

Ectomycorrhizae are formed by mutualistic interactions between fungi and the roots of woody plants. During symbiosis the two organisms exchange carbon and nutrients in a specific tissue that is formed at the contact between a compatible fungus and plant. There is considerable variation in the degree of host specificity among species and strains of ectomycorrhizal fungi. In this study, we have for

The electron structure of several highly charged ions, belonging to the Mg, Ne, Mn, Fe, Co, Ga and Ge isoelectronic sequences, has been experimentally studied by means of two techniques, beam-foil spectroscopy, BFS, and the spectroscopy of laser-produced plasmas, LPP. The investigations were carried out at Lund University, LU, in 1989-90 and at the China Institute of Atomic Energy, CIAE, Beijing,

Esterification of p-hydroxybenzoic acid, a very weak estrogenic compound, with the daucane alcohol jaeschkeanadiol (1b) leads to a spectacular magnification of the estrogenic activity. To identify the structural elements responsible for this effect, the terpenoid core of jaeschkeanadiol p-hydroxybenzoate (ferutinin, 1a) was modified, capitalizing on the presence of two functionalities, the monoacy

Research at the division of Packaging Logistics, Lund University, has been performed in numerous areas, ranging from organisational learning and sustainability to process integration and service development. One of these is the new and complex research area of traceability. When it comes to food scandals, from the mad cow disease at the end of the 90s to the more recent incident where glass has b

Objective. To determine the prevalence of diabetes and impaired glucose tolerance after gestational diabetes mellitus in relation to different categories of glucose tolerance during pregnancy. Design. Prospective study. Setting. Four delivery departments and three hospitals in southern Sweden took part in recruitment and follow-up. Population. Women undergoing a 75 g oral glucose tolerance test du

The purpose of this paper was to, from a user perspective examine and describe how the cares of people with learning disabilities in two care residences fulfil stated quality objectives. Another purpose was also to examine if the quality tool, Quest, was useful when evaluating Swedish conditions. The result shows the conditions were good for performing high quality care, but there are certain need

The purpose of this thesis was to study how well the MRD-model (Mould Resistance Design) co-using the hygrothermal calculation software WUFI Pro 6 can predict mould growth in roof structures within long periods of time. The study was done on eleven roof structures situated at Malmberget within Gällivare Municipality between the years of 1961 – 2012 in WUFI Pro 6 (the structures were built around 1

Climate hazards are increasing globally both in their intensity and frequency, requiring more integrated approaches that also strengthen national leadership over disaster management. Mobilizing resources ex-ante has been demonstrated as an effective way of reducing the impacts of hazards on livelihoods and protecting development gains, while social protection (SP) has also been demonstrating capac

Thesis purpose: The purpose of this study is to understand what impact social media influencers have on consumers' online behaviour. We further aim to understand the interrelationship between social media influencers and online impulse buying behaviour. Methodology: This study has utilised a qualitative methodology based on a social constructionist philosophical position. The study has adopte

Cosmetic innovations are about finding high performing creative solutions that deliver into the consumer trends. The consumer trend within the cosmetic industry is currently driving a growing demand for more clean, natural skin care products with sustainable credentials. Enhanced delivery to and interaction with the skin can be achieved through knowledge-based design and characterization of delive

Den 1 juli 2021 blev det straffbart att låta barn bevittna brott mellan närstående. Brottet fick rubriceringen ”barnfridsbrott” och återfinns i 4 kap. 3 § BrB. Kriminaliseringen av att låta barn bevittna brott mellan närstående bemöttes av positiv respons från de flesta remissinstanserna. Trots att barnfridslagen välkomnades med öppna armar fanns en viss oro för hur lagens utformning skulle fungerOn the first of July, 2021, it became a crime in Sweden to allow children to witness crimes between relatives. The crime is called ”barnfridsbrott” and exists in Chapter 4, Section 3 in the Swedish Criminal Code. The criminalization of allowing children to witness crimes between relatives was met with a positive response from most of the consultation bodies. Although it was welcomed with open arms

This paper addresses the currently existing research gap regarding the lack of a clear definition and categorisation of lifestyle entrepreneurs. The primary objective is to examine the different core dimensions of lifestyle entrepreneurs and develop a comprehensive concept on their basis. This study adopted an abductive approach to explore the understanding of lifestyle entrepreneurs. By utilising

In this study, Dissolved Organic Matter (DOM) quality was analysed through its optical properties. Samples from the estuarine waters of the Beagle Channel and oceanic ones of the Burdwood Bank were examined in order to understand how DOM quality was changing. The focus of the study was to determine whether the environmental variables or the microbial community were the main driver in DOM compositi
