When the metabolic activity of bacteria is exploited by the food and biotechnology industries, freeze-drying is commonly used to produce concentrated bacterial cultures with enhanced storage stability. The freeze-drying tolerance of the probiotic strain Lactobacillus reuteri and the biocontrol agent Pseudomonas chlororaphis has been characterized in this work. Lb. reuteri was found to have higher

The MBA case method of how to use cases steam from Harvard and has almost become a norm for what the case method represents concerning the purpose, form and content. However, the Lund University School of Economics and Management (LUSEM) way of using cases differs from the MBA Case Method in several important aspects. This paper discusses the potential merits of using an alternative approach (LUSE

It is often assumed that a main function of gestures is to compensate for expressive difficulties. This predicts that gestures should mainly occur with disfluent speech. However, surprisingly little is known about the relationship between gestures and fluent vs. disfluent speech. This study investigates the putative ompensatory role of gesture by examining competent speakers’ and language learners

The purpose of this bachelor thesis is to study how the social workers understand the sexual exposure adolescents become subject to make themselves subject to on the Internet, as a social problem or a transformation of a sexual behavior. Two methods were used in this study; both a questionnaire and deep interviews with four social workers. The main result of the study shows that social workers, ac

This is a study about the relationships between stress tolerance and ill health in the workplace. Thirty-two police officers in Lund, Hörby and Helsingborg were investigated in the study: 25 male and 4 female officers, 9 police inspectors, 15 event - controlled police, officers 1 near police officer, 4 external command police officers, 2 internal command officers were tested. Stress tolerance was

End-of-life management of cars in Europe is regulated by a common legislative framework since 2000, when the Directive 2000/53/EC on end-of-life vehicles (ELVs) was adopted. The objectives of this legislation are: prevention of waste from ELVs through design improvements, and facilitating better recycling and treatment of ELVs by improving environmental performance of treatment facilities and atta

The final purpose of this project is to create a platform that leads to the improvement of the braking feeling by the users of heavy vehicles. The complexity of the problem lays on the different constraints: geometrical and functional, and as well on the interaction with a human operator. The task is to design a new electronic brake pedal, with the possibility to change the relationship between fo

The use of area-based approaches in urban regeneration is widely accepted in the European community. As these projects are based on the context of the focal area, there is no one-size-fits-all solution on how to design and implement those. The Eco-city Augustenborg project is an environmentally-led urban regeneration project initiated in Malmö in 1998. Today, fifteen years after the project was in

I svensk rätt gäller som utgångpunkt att medicinska och psykiatriska åtgärder inte får ges utan att patienten har samtyckt till dem. Undantag från denna huvudregel finns, till exempel när tvångsvård ges med stöd av lagen om psykiatrisk tvångsvård (LPT). En utgångspunkt är dock att patienter inom svensk sjukvård ges självbestämmanderätt. I vilken grad minderåriga patienter ska erkännas självbestämIn Swedish law, an important main rule is that medical and psychiatric measures cannot be given without consent from the patient. There are exceptions from this rule, f.ex. when treatment is given involuntary under the Act on Compulsory Psychiatric Care (LPT). But as a main rule, patients in Swedish health care have the right to self-determination. To which degree children shall be given the righ

The objectives of the present study were to estimate long-term risks of osteoporotic fractures. The incidence of hip, distal forearm, proximal humerus and vertebral fracture were obtained from patient records in Malmo, Sweden. Vertebral fractures were confined to those coming to clinical attention, either as an inpatient or an outpatient case. Patient records were examined to exclude individuals w

Glioblastoma multiforme is the most common and aggressive malignant brain tumor in humans, and the prognosis is very poor despite conventional therapy. Immunotherapy represents a novel treatment approach, but the effect is often weakened by release of immune-suppressive molecules such as prostaglandins. In the current study, we investigated the effect of immunotherapy with irradiated interferon-γ

Current theoretical attempts to understand the reversible formation of stable microtubules and virus shells are generally based on shape-specific building blocks or monomers, where the local curvature of the resulting structure is explicitly built-in via the monomer geometry. Here we demonstrate that even simple ellipsoidal colloids can reversibly self-assemble into regular tubular structures when

Dinophysis norvegica is a commonly occurring dinoflagellate species and a producer of diarrhetic shellfish poisons. Natural samples were collected from Trondheim fjord, Norway, to analyse nutrient (O, C, N, P) and toxin (dinophysitoxins [DXTs], okadaic acid [OA], pectenotoxins [PTXs]) content in D. norvegica cells. Nutrient and toxin analyses were also carried out on cells grown under nutrient-suf

The productivity of agricultural and forest ecosystems in regions at higher latitudes is to a large extent governed by low temperature and moisture conditions. Environmental conditions are acting both above- and below-ground and regulating carbon fluxes and evapotranspiration. However, the understanding of various feedbacks between vegetation and environmental conditions is still unclear. In this

Background: For many years there has been a debate as to which is the method of choice in treating patients with esophageal perforation. The literature consists mainly of small case series. Strategies for aiding patients struck with this disease is changing as new and less traumatic treatment options are developing. We studied a relatively large consecutive material of esophageal perforations in a

Complementary measures for the assessment of patient thermoregulatory state, such as subjective judgement scales, might be of considerable importance in field rescue scenarios where objective measures such as body core temperature, skin temperature, and oxygen consumption are difficult to obtain. The objective of this study was to evaluate, in healthy subjects, the reliability of the Cold Discomfo

Modern industrial robots are traditionally programmed to follow desired trajectories, with the only feedback coming from the internal position/angle sensors in the joints. The robots are in general very accurate in tracking the desired motion, and they have become indispensable in many applications, such as spot welding and painting in the automotive industry. In more complex tasks, such as physic

BACKGROUND AND PURPOSE: Distal radius fractures are most often treated nonoperatively, but sometimes they are treated surgically when deemed unstable. Based on the literature, a consensus protocol for treatment has been developed in southern Sweden to aid clinicians in their decision making. We evaluated the results of this protocol prospectively using a validated outcome instrument (DASH) in a la

This paper presents a novel method for the analysis of heart rate variability (HRV) during exercise stress testing enhanced with respiratory information. The instantaneous frequency and power of the low frequency (LF) and high frequency (HF) bands of the HRV are estimated by parametric decomposition of the instantaneous autocorrelation function (ACF) as a sum of damped sinusoids. The instantaneous
