Nearly one third of the global food is wasted. Microbial spoilage is a major factor in food waste, and it can happen at any point along the supply chain. Greenhouse grown English long cucumbers, one of the most important vegetable crops grown in Europe, were studied for weight changes and the presence of microbiological populations during the shelf life in this project. The main methods used in th

This project tested the potential of plant based milk powders to function as an animal-based milk powder by testing them on multiple characteristics. The powders were produced using spray drying techniques, obtained using formulations differentiating in protein amount, ratio of maltodextrin:sucrose and two different protein sources. The different ratios were 100% sucrose; 100% maltodextrin; 50% ma

For centuries, people have appreciated the taste of wild mushrooms which can be found in nature throughout the European continent and the Fennoscandian peninsula. This is especially so for those of the order of Cantharellales, where you find the Golden Chanterelle among others. Today the commercial aspect of mushroom harvesting has resulted in regulations and guidelines set out by the Nordic Counc

Electrification of the automotive industry calls for high performing electric engines. Since the use of iron from primary sources in the production of engine cores has a high environmental impact, it would be beneficial if they could be made mostly from recycled materials. Soft magnetic composites used as cores in electric engines have lower mechanical strength compared to the alternatives. This i

Popular Abstract in English The word “combustion” describes a number of physical and chemical processes, whose common characteristic is an interaction between fuel and oxygen and their subsequent transformation into products, such as CO2 and water. Even though the process is often described as a single chemical reaction between fuel and oxygen, in reality, their chemical transformation requires maThe laminar burning velocity and the flame structure are common targets for combustion studies aimed at detailed kinetic model development. In the present work, fuels relevant to hydrogen combustion were considered. The laminar burning velocity of rich and lean hydrogen flames was studied experimentally and numerically, including its pressure dependence in rich mixtures and temperature dependence

Context Approximately 10% of women with invasive epithelial ovarian cancer (EOC) carry deleterious germline mutations in BRCA1 or BRCA2. A recent article suggested that BRCA2-related EOC was associated with an improved prognosis, but the effect of BRCA1 remains unclear. Objective To characterize the survival of BRCA carriers with EOC compared with noncarriers and to determine whether BRCA1 and BRC

Physical inactivity has been identified as the fourth leading risk factor for global mortality and healthcare systems play a major role in increasing physical activity among the population. Physical activity on prescription (PAP) is a non-pharmacological method used in Swedish healthcare to prevent and treat disease. Primary health care is the first level of care, in a strong position to work for

Wireless adhoc networks transmit information from a source to a destination via multiple hops in order to save energy and, thus, increase the lifetime of battery-operated nodes. The energy savings can be especially significant in cooperative transmission schemes, where several nodes cooperate during one hop to forward the information to the next node along a route to the destination. Finding the b

Background: The Epidermal Growth Factor Receptor (EGFR) activated Extracellular-signal Regulated Kinase (ERK) pathway is a critical cell signalling pathway that relays the signal for a cell to proliferate from the plasma membrane to the nucleus. Deregulation of the EGFR/ERK pathway due to alterations affecting the expression or function of a number of pathway components has long been associated wi

To identify prognostic factors after hepatocellular carcinoma (HCC) recurrence after liver transplantation (LT). We retrospectively reviewed the combined experience at Toronto General Hospital and Hospital Vall d'Hebron managing HCC recurrence after LT (n = 121) between 2000 and 2012. We analyzed prognostic factors by uni- and multi-variate analysis. Median follow-up from LT was 29.5 (range 2-129.

Är en sur vattenmiljö dålig för bakterier? Bakterier finns överallt på vår planet och är bland annat viktiga för nerbrytningsprocesser i naturen. De bakterier som klassificeras som heterotrofa livnär sig genom att bryta ner döda växt-och djurdelar och omvandla detta till energi. I sjöar och vattendrag utgör dessa bakterier en central del, då de kan utnyttja resurser som är otillgängliga för andraAbstract The environmental pH is an important factor affecting bacterial physiology and function as well as community composition in soil and marine ecosystems. However, studies of the effect of pH on bacterial function in limnic systems have been scarce. Considering studies in soil where it has been conclusively confirmed that bacterial growth rates (μ) are considerably lower in a low pH environ

Atmospheric aerosols are of great importance climatically due in part to their ability to scatter and absorb solar radiation. However, their influence in our changing climate holds the greatest uncertainty of all atmospheric components. With this in mind, there remains a necessity for advancement in monitoring and measurement techniques. The aim of this investigation is to consider the current mea

One of the essential engineer’s jobs is to achieve the most economical technical solutions. Weight optimization is important since it provides a structure that can carry the applied loads in addition to fulfilling the structural requirements. In this project, a Matlab-algorithm has been developed to find the optimum design of steel portal frames according to “Eurocode 3: Design of steel structures

The primary rule of absolute duty to prosecute is stated in 20:6 RB. This means that the prosecutor is obliged to engage prosecution when there is sufficient evidence for a conviction. The possibility of waiver of prosecution is stated in 20:7 RB and is an exception from the absolute duty of prosecution. The prosecutor can decide to waive prosecution for minor offense not resulting in any other pe

In the automotive industry, it is common that the customers provide the suppliers with the necessary packing material needed for delivery of the goods. The reason for this is that it makes the handling and unpacking of incoming goods at the customer easy, but it also makes sure that the quality of the packing material is high, and that the transportation damages of the goods are minimised. It shou

The starting point and reoccurring theme of this work is the accommodation of the effective judicial protection of individuals in the European Union system of review of validity of its acts. The discussion of this issue was intense during the decade before the adoption of the Lisbon Treaty due to the Court of Justice’s judgments in the two famous cases Unión de Pequeños Agricultores and Jégo-Quéré

Z39.50 is a standard protocol designed to create an interface between diverse computer databases for diverse information needs. Since it has to be adjustable it is also complex and demands a certain degree of expertise when being set. However, the aim of this paper is not to make a theoretical description but to examine certain conditions in practice. From the perspective of Swedish research libra

The theoretical focus in this master is information retrieval (IR), and especially the part of IR that includes interactivity. This research is by some researchers called IIR. Our principal aim was to examine if search engines on the WWW are taking advantage of research results from IIR research. A way to do this is to look at the application of special features, in this case query expansion (QE)

Corporal punishment of children is a widespread practice across the world. The implications of such violence consist of both physical and mental injuries and children are very vulnerable to such treatment. The Convention on the Rights of the Child was put into place, by States from all across the world, for the purpose of granting children a better protection in society. Today, all but two States

The realisation of the inner market meant that all border controls between the Member States of the European Community were to disappear, so that the four freedoms, workers, capital, services and goods, could cross the borders without problems. But in order to keep the security in a Community with no borders, the external border controls had to be strengthened. This was necessary to keep out drugs
