Individuell tillväxt och substratval hos en lokalt differentierad population av Asellus aquaticus

Local differentiation may occur during a short period of time and is part of the formation of new species. The isopod Asellus aquaticus is an example of a species in which local adaptation has occurred during a short period of time. An establishment of stonewort (Chara spp.) vegetation in Lake Tåkern (in the 2000) resulted in two different Asellus ecotypes; a lighter pigmented, smaller one that lives among stoneworts grazing periphytic algae, and a darker, larger ecotype that feeds on decaying leaves in reed (Phragmites australis vegetation. The purpose of this study was to examine whether there are differences in growth between ecotypes, depending on whether the food was periphytic algae or leaves, and to study the choice of substrates between the two food types. For the study, animals from both habitats were brought in from Lake Tåkern to the laboratory.

Uppfödning av okastrerade hangrisar - ett alternativ till obedövad kirurgisk kastrering av smågris

Pigs kept for meatproduction are often surgically castrated to prevent aggression and boartainted meat. Castration without analgesia and anesthesia is painful and causes a lot of stress to the pig. There are alternatives such as to surgically castrate the male pigs with analgesia and/or with anesthesia, immunocastrate or keep them as intact males. In Sweden the most common practice is to surgically castrate the pigs before they are seven days old. The impact on the pig is that the incision causes pain and stress, which may lead to changes in behaviour, reduced appetite, reduced growth and a higher risk of infections.

Strategier mot urban sprawl i svenska städer : En fallstudie av åtta svenska kommuners arbete

Urban sprawl är ett problem i hela världen. Ekonomi, hälsa, miljö och jordbruksmark är några saker som stadsutbredningen har effekter på (Habibi, 2011). I USA började problemen med urban sprawl efter andra världskriget när möjligheter till billiga bolån skapades. Detta gjorde att fler människor hade möjlighet att flytta till enfamiljshus i förorterna och användandet av bil som transportmedel ökade (Duany, 2010). Stadsutbredningen i Sverige startade efter andra världskriget då bilismen ökade även här.

EAS-tagg med fuktsensor : Design och utvärdering av EAS-alarmteknologi för fuktdetektering

Electronic article surveillance (EAS) is widely used in shops and libraries together with an RF-tag attached to the goods or books in order to prevent shoplifting. By implementing the addition of a moisture sensor to the RF-tag, other functions become possible, including the ability to use as an alarm with regards to frozen goods, which have been shipped but which have melted and have, subsequently, refrozen. In- relation to care for the elderly, one time-consuming step involves checking whether there is the necessity for a change of diaper and this can, instead, be based on an RF-tag with an EAS-system alarm. A preliminary investigation was made using the moisture sensors, which involved how the resistance changes when liquid and/or heat is applied. A simulation of the LCCR circuit (RF-tag with the sensor) was conducted in order to determine how the resonance frequency changes for different resistances levels.

EN HANDLEDNING I DESIGN- OCH STRUKTURUTVECKLINGSFASEN AV EN WEBBPLATS : Med fokusering på användbarhet

There are a huge number of books and articles written in the field of usability and about the art of giving the user the opportunity to find the information he is trying to reach while browsing the website. The writers of these books are handling guidelines that are recommended to be followed, as well as describing their own views, ideas and theories of the subject. We found an interest to research the different possibilities, if any, to develop a website optimal for the user from a usability point of view. Another thing we noticed was that a need of a substantial guidance existed in website development aimed for recently started companies.New theories and rules regarding usability, which are seen as superior to the old ones and therefore replaces them, is not created that often. This is different from other IT related subjects.

Health added-value food : the Swedish retail market

Diet and lifestyle are closely interrelated and believed to have a significant influence on four major public diseases - cardiovascular disease, cancer, hypertension and obesity, but also affects functional deficiencies like gluten- and lactose intolerance. Health added-value foods are thought to reduce health-related risks or delay the onset of these major diseases. Therefore, interest among scientists, researchers and the public in general has been growing remarkably over the last decade regarding these special foods. The Swedish market seems to be a good target for health added-values food. However, as there are many risks and cost factors involved for companies to enter the market or invest in R&D, it is important to take a step back and analyze the current market situation.

Samverkan- gemensamma mål med omsorgstagaren i fokus : En kvalitativ studie om samverkan mellan biståndshandläggare och enhetschefer i äldreomsorgen

Animal welfare is of increasing concern in present society. In commercial pig farming, animal welfare problems are common. One of the causes for these problems is the barren environment in which pigs are housed, which can cause oral manipulation of pen mates. Providing straw might be one solution to this problem. Another solution could be reached through genetic selection.
