Chemical and sensory analyses of juice, cider and vinegar produced from different apple cultivars

The interest for locally produced food is increasing due to consumer concern about the environment, distrust of industrial foods and a demand for high quality products. Apple is the predominant fruit crop in Sweden, and by processing apples into cider and vinegar, these products could significantly contribute to the development of the market of local foods.In this study different yeast types and different bacterial cultures were evaluated for their suitability in cider and vinegar production from cloudy apple juice. Ten apple cultivars (Aroma, Baldwin, Belle de Boskoop, Bramley, Cortland, Gravensteiner, Ingrid-Marie, Jonathan, Rubinola and Spartan) were also evaluated for their suitability for production of juice, cider and vinegar. Chemical analyses including total soluble solids, titratable acidity and total phenols were performed on the products along with sensorial evaluation by taste panels.The yeast strains were shown to have an effect on fermentation rate and the resulting content of total phenols in ciders fermented from cloudy apple juice. Dry commercial starter strains gave a higher appreciated cider compared to cider that was spontaneously fermented, and the ale yeast Safale S-04 was concluded to be the most suited for fermentation of cloudy apple juice.For vinegar production, the bacterial culture had an effect on TSS, but not on any other chemical or taste characteristics.

Erfarenhet, föränderlighet och arv Gottfrid Adlerz. Om människans ursprung och striden om kulturvärdena

The purpose with this essay is to analyze Adlerz writing within the context of the fiery debate in the 1880?s between the liberal so called ?cultural radical? members of the student organization called Verdandi, and the conservative, uniform oskarian culture named after the Swedish king of the period. I have applied a version of Quentin Skinner?s method, which focuses on the context of a specific writing in order to find out the authors intention, the effect the author hoped to achieve. My questions regard certain themes I discovered in the text and, more importantly, the relationship between these themes and the surrounding debate.

Hästavmaskningsmedels påverkan på miljö och välfärd

Healthy, natural pastures is very valuable for biodiversity in the form of both plants and animals. An efficient use of pastures helps to preserve biodiversity, but grazing animals needs to be de-wormed to keep them healthy and to prevent harmful parasites spread on the pasture. The awareness about the environmental impact of the frequent use of deworming agents is low among the public. Some people are unaware that the absorption in horses of anthelmintics is incomplete, which make the circumstances about enviromental effect important to investigate further. The scientific evidence in this area is limited and more studies and trials are needed to deepen the knowledge about the effects of anthelmintics in the environment.

Miljöcertifierade kommersiella byggnader : Undersökning av ekonomisk ansvarsfördelning mellan hyresgäst och fastighetsägare

The Swedish commercial real estate market is in the current situation globally affected and is actively interacting with the rental and capital markets through international tenants and investors who are setting new demands on the property owners. The European Union has set new requirements as well in purpose of reducing humanity?s negative effect on the climate and therefore the international real estate market has introduced Green Building-certificates in order to decrease the real estate industry?s environmental impact.Certificated buildings with low energy consumption are a more common sight in Sweden these days. The development, however, could go even faster if there was not certain difficulties between property owners and tenants. Previous research has revealed that tenants do not always have knowledge about, or may have access to the economic benefits that a green building can provide.

Att skilja på sak och person - Hur ökad personifiering i media kan leda till bättre politisk kunskap hos mottagarna

Mass media is becoming more and more personalized and despite common ideas it could actually be a good thing. Instead of affecting the actual content of news coverage it might only have an effect on the way in which news are presented. Famous politicians more regularly become symbols and synonyms for their parties or for the government and are being used to create interest in the beginning of articles.Those are the results from a content analysis of the newspaper coverage of the Swedish parliamentary election in 1976 and 2006 in which the scientist categorized each article in one of four ideal types, counted quotes and analyzed whether personal names were interchangeable with party names without affecting the content. All three methods showing that it is the presentation, not the content, which has been personalized.At the same time, psychology-science tells us about the human brains associative learning processes, where memorizing becomes far more efficient when the information can be connected to an already known person. Increased personalization of news might therefore increase the political knowledge of the receivers..

Att färdas i symbios : ett gång -och cykelstråk anpassat efter trafikanternas rörelsemönster och behov

The aim of this paper is to examine the layout of public spaces and its effect on human behavior with focus on the relation between pedestrians and cyclists movement patterns in a specific path. The study emanates from the security aspect of pedestrians and cyclists, and builds upon previous theories and empirical studies about perception, security, information design, environmental psychology and behavior. The result shows that individual behavior and movement pattern differs with age, purpose, physical- and other conditions, and layout of the surroundings. A design proposal for improved layout of a path and a node between different oncoming paths has been developed to aid the users? needs, where a separation of walkways and bike lanes forms zones of security for the purpose of better orientation and a better flow between the users..

Privata säkerhetsföretag - Våldet som handelsvara

This essay tries, in different levels, to explain and create a deeper understanding for the phenomena ?private security companies?. By using Mary Kaldors theory about new wars, I will come to the conclusion that the insecurity that these wars create is an important part in understanding the emergence of a security need that these private security companies can provide. Later I investigate and explain howthe neoliberal privatization policy that is spreading through the world today has laid ground for development of the private security industry. When I have answered these questions I analyze how the private security companies can affect the state, war and peace both positively and negatively.
