Problem med röda hamburgare efter tillagning : bakgrund och möjliga lösningar

Persistent pink in beef patties and hamburgers is a problem in the meat industry that has been known for a few decades. It is a costly problem as it can give rejections of food by consumers. Studies around the world have tried to solve the problem but it still remains a mystery. There are many different theories of what is causing the red colour. Some of the most likly theories are reducing hemocromes, high microbiological loads, contamination of nitrite or organic/non organic substanses, DFD meat etc.

Förekomst av leukocyter i råsperma hos semingaltar :

Detection of leukocytes in semen from boars is part of the routine control of semen quality. Leukocytes in semen can cause damage to spermatozoa that leads to impaired fertilization. In the artificial insemination (AI) industry there are standard routines for the quality control of the boars and of the neat semen before use. Since 2001, Quality Genetics has not done the leukocyte examination on semen samples from boars which are used for the production of pigs for slaughter. The purpose of this study was to investigate the occurrence of leukocytes in semen from AI-boars. The questions addressed were whether there are boars that have leukocytes in their semen and how frequently it occurs and, moreover, if there are differences between breeds, or even between individuals whose semen was checked before use in AI-dose production compared to those which were not. The study included a total of 135 AI-boars, of which 67 were Hampshire, 35 Yorkshire and 33 Landrace, all belonging to Quality Genetics AI-station in Hållsta.

Att göra stad. Om demokrati och deltagande i det offentliga rummet

Malmö has often been described as a segregated city, with relatively low democratic participation and high poverty and alienation. Behind this kind of statements we often find a material reality, with unequal distribution of assets and potentials that needs to be taken into consideration for political action. At the same time this categorisation of people into different groups can take stigmatising effects and result in increased inequality.I find the theoretical basis for my thesis in Lefebvre?s writings on ?the right to the city?, that shortly means that all inhabitants of a city have the right to take active part in the constantly ongoing process of producing and reproducing the city ? on all levels, from a hands-on everyday life level to a more abstract political level.With an interdisciplinary approach, where the right to the city is discussed in relation to citizenship, presence, representation and public space, I try to understand the connections between democracy, participation, justice and equality. These discussions are then applied to examples from Malmö; both publically initiated projects and individual physical markings in the city.

Fire impact in the wood quality and a fertilization experiment in Eucalyptus plantations in Guangxi, southern China

Chinas government has a multifunctional program for a more sustainable forestry since 2000. This six key forest programs goal is to develop a more sustainable forest sector but also take environment consideration. The state forest administration in China has decided to create 5.8 million hectare of fast growing and high yield forest. Eucalyptus has showed to have good properties for pulp and timber production and therefore Eucalyptus plantations are under development in costal areas in southern China. By adding extra nutrients, growth can be enhanced in Eucalyptus plantations.

Effects of brown bear (Ursus arctos) odour on the patch choice and behaviour of different ungulate species

The return of large predators to regions where they were previously extirpated has created a need for knowledge about their effect on prey species, not only their lethal but also their behavioural or risk effects. In this study the behavioural risk effects of brown bear (Ursus arctos) were tested on fallow deer (Dama dama), roe deer (Capreolus capreolus), red deer (Cervus elaphus), moose (Alces alces) and wild boar (Sus scrofa). This was done by using patches of fur to simulate the presence of the novel predator (brown bear), a novel nonpredator (reindeer (Rangifer tarandus) and no fur as control. These three treatments were then compared. The response variables measured were increased vigilance, decreased feeding time and change in patch use.

Riskfaktorer för förlossningsdepression samt förebyggande åtgärder ? En litteraturbaserad studie

Introduction: Approximately one in eight women suffer from postpartum depression, which can affect them for a period of weeks or even years. Postpartum depression does not only affect the mother, it also has a negative influence on the rest of the family. Postpartum depression can also lead to negative consequences for the development of the infant. It is an illness that is still considered a taboo, a fact that makes it hard to identify among women who are affected. Aim: The aim of the study was to examine cases where there is a connection between social economic status (SES) and the presence of postpartum depression.

Habitat preference and dispersal of a sandassociated beetle, Apalus bimaculatus

Species that have a high degree of specialization and poor dispersal ability can be more prone to extinction than more generalist species and good dispersers. How these species traits affect the viability of populations is dependent on landscape factors,such as isolation and connectivity. Additionally, interactions between species (e.g. symbiosis), and how these interactions vary spatially and temporally can have a large impact on populations. When the range and habitat areas of a species continuously decrease, management strategies are often needed if the species shall be able to survive.

Ergonomi ur ett hälsoperspektiv - En studie genomförd på en processindustri i södra Sverige

Syftet med detta arbete är att undersöka ergonomins och hälsans förutsättningar på en processindustri i Sverige samt att ta fram förslag på förbättringar och ett träningsprogram för personalen på industrin. För att minska risken för belastningsskador är det viktigt att individen arbetar med ergonomiska arbetsställningar. Om arbetsgivaren förser arbetstagaren med så goda förutsättningar som möjligt att tillämpa ergonomiska arbetsställningar samt erbjuda friskvård kan kostnaderna för sjukfrånvaro sänkas betydligt. Metoder som använts är kortare observationer följt av de ergonomiska uträkningarna OWAS och RULA. En interventionsgrupp inom produktionen fick besvara en enkät, som även fylldes i av en kontrollgrupp som bestod av administrationspersonal (kontorspersonal).

Reproductive physiology of the female cat

The cat is one of our most common pets. Understanding the reproductive physiology of the queen is important, not only for the knowledge of our domestic cats but also for wild undomesticated feline species, many of which have been reported endangered. Understanding the mechanisms behind the estrous cycle, ovulation and pregnancy is also important for handling the feral cat populations that are a problem in several countries. The purpose of this literature study is to look into the hormonal patterns of the reproductive physiology of the female cat, with focus on ovulation, pregnancy and pseudo-pregnancy, and from this information determine in which fields more research would be needed. The female cat is seasonally polyestrous in Sweden, meaning that she can have several estrous cycles during the breeding season but goes through a long period of reproductive dormancy during the darker months of the year. The queen is considered an induced ovulator, with copulation triggering the release of luteinizing hormone (LH) from the pituitary gland needed for ovulation.

Differentiering och framgångsfaktorer på en ständigt växande marknad : Undersökning av bemanningsbranschen

Today it is mandatory for every college or university student to pay a union fee to their student?s union. The fee is mandatory and is a payment for writing examinations, receiving grades. The fees purpose is also intended to secure the education quality and student influence. In the presence of the abolishment of the union fee the Swedish student?s unions stand before an uprising competition between themselves and most likely a decrease in membership.

Bacterial contamination of eggshells in deep litter floor systemsand conventional cages in Jordan

This study was carried out in Jordan with the purpose to investigate the bacterial microflora of egg shells from cage systems and from deep litter floor systems. Another aim wasto get a general impression of the hygiene, at farm level, of egg production in Jordan andthe factors affecting it.Eggs from two cage systems and three floor systems were analyzed, regarding bacterialcontamination of the egg shells. Egg samples were taken from the storage room, the eggcradle in the cage system and from the nest and floor in the floor system. To get a generalimpression of the hygiene at the farms, swab tests and air tests were performed. Swab testswere performed with a sterile cotton swab at the same units as the eggs were sampled andair tests were performed by opening petri dishes where the hens were staying.

Vattenkvalitén i Fredstorpsbäcken - dikad bäck på fastigheten Rämningstorp i Skara kommun :

The estate of Rämningstorp in the region of Västergötland in southern Sweden is administered by the holding trust company Skogssällskapet i Skövde. In 1999 measures were taken by Skogssällskapet to drain the stream Fredstorpsbäcken as a means to increase the forest productivity of the surrounding lands, which are situated on the estate of Rämningstorp. Almost immediately after the drainage, the streamwater turned turbid and a landowner downstream reported the issue to the county administrative board of the region. The aim of this thesis was firstly to analyse the suspended matter that appeared during summer/autumn and secondly to explain why it came to be. Initial hypotheses for the explanation to the greyish turbid water were that it was either 1) a chemical/biochemical precipitate, or 2) an bacterial/algal blooming.

Den abstrakta tråkigheten : villkor och möjligheter, utifrån ungas perspektiv, att relevansgöra digitala medier som en resurs för lärande i skolan

Children and teenagers of today have grown up with digital media. According to Olle Findahl's report "The Swedes and the Internet" (2009), adults as well as children are online more and more. Our experience is that at many workplaces as good as everyone use computers and everyone is expected to have digital skills. However at most schools the reality is far from this. According to Findahl's report from 2009, 99 percent of all pupils (in Sweden) have access to computers and Internet, yet it is rare that they get school assignments where the use of Internet is acquired (Findahl 2009).The purpose of our paper is to understand how digital media can be used as a resource for learning, through the perspective of young people.
