Flodhästens matvanor och dess lättjefulla livsstil
Flodhästen är en av Afrikas största växtätare och har ett speciellt födosöksbeteende då de endast betar på natten. Under dagen stannar de i eller väldigt nära vattendrag eller dypölar där de är fysiskt ganska inaktiva. För att klara av att endast äta en begränsad del av dygnet måste flodhästen ha olika fysiologiska, anatomiska eller beteendebaserade anpassningar till detta. Syftet med den här litteraturstudien är att reda ut varför flodhästen endast betar på natten och hur är de anpassade till detta.
Att de endast betar på natten beror till stor del på att deras hud spricker om de vistas i solen för länge. Dessutom sparar de energi på att sköta sin termoreglering genom att bada istället för att svettas.
De är framförallt gräsätare men det har visats att de äter blad, örter, träd och buskar i större utsträckning än som tidigare har trots.
Bikeshare - Elcykel : Framtagning av dockningsstation till cykeldelningssystem
The project was carried out together with OC Off Course who manufactureand distribute mainly electric bikes.In today?s society, alternative sources of transportation becomes more andmore present and several bicycle sharing programs arises in major citiesacross the world every year.Something that doesn?t exist too much as of yet is bike sharing programsthat uses electric bikes. An electric bike is a convenient way oftransportation as well as a good way of avoiding traffic. With an electricbike you avoid having to sweat when biking over hills or when you need totravel over longer distances.The goal of this project is to develop a bike sharing station according tothe functions need to be met.This thesis Is based on Fredy Olsson´s methods principkonstruktion aswell as a couple of concept generating methods from Kenneth Österlin.From this, a number of sketches were made that later was evaluated inseveral steps in conjunction to a set of specifications. A 3D model of theselected concept was later made in CatiaV5 for a complete product..
Hästens välfärdsproblem relaterade till utfodring
Hästen har länge varit ett användbart och uppskattat djur av människan. Ända sedan domesticeringen för 6000 år sedan har hästen använts till krig, som draghjälp och för nöje. Hästen började sin utveckling som en mindre bladätande fyrtåad häst till dagens större entåade gräsätande häst. Denna utveckling var nödvändig för hästens överlevnad med anledning av ökad konkurrens av betet och förändrat klimat.
Dagens hästhållning skiljer sig från den miljö hästen levde i som vild.
Svenska kyrkan i kris : Sambandet mellan demografi och Svenska kyrkans medlemsandel
Our aim in this work has been to redesign ModernFamilies and make a user-friendly interface for people with aphasia. The focus has been to identify general issues they might face while using different technology and applications, in order to find better alternative design for ModernFamilies, with a focus on usability. To approach this issue, we used a qualitative method. Our study includes several interviews and observations preformed in conjunction with the AGNES project (AGeing in a NEtworked Society) and speech therapists. Aphasia requires simple design that in the same time gives them support to understand and use technology and different applications.
Testdriven utveckling (TDD) ? En metod för att minska underhållskostnader i mjukvaruprojekt?
The maintenance phase within software projects is typically very expensive in terms of resources. The activities of this phase are largely focused around some form of modification of program code. This leads one to consider if there are alternative methods of code production that results in code that allows for less costly modifications. This thesis has its basis in a subset of those concepts which research has shown to provide more flexible code. Once this subset is established, connections are made between the concepts within the subset and claims of benefits provided by the use of Test Driven Development (TDD) methodology.
The effect of domestication on insect resistance in cotton : bioassays with the insect herbivores Spodoptera littoralis and Agriotes spp.
A plant's defensive ability against herbivore attack can be influenced by many different factors, one of them being domestication. During human selection to improve the yield of plants, the resistance against herbivore attack can have been lowered, due to a trade-off for use of resources between these traits in the plants.
In this thesis I investigated the effect of domestication on resistance against herbivorous insects in cotton plants. I used different varieties and species of wild and domesticated cotton in three different experiments. A feeding assay was conducted, the mortality, development
time and pupal weight of larvae of the Egyptian cotton leaf worm Spodoptera littoralis was studied. In a second experiment the preference of the root-feeding beetle Agriotes spp.
Gemensam struktur för den kommunala ekonomistyrningen
Municipalities must establish budget annually but they are free to decide how the governance should be designed, this can lead to lack of consistency and measurability within and between municipalities. The purpose of this thesis was to present a proposal for a unified and more measurable financial structure of a municipality where this was lacking. In our theory we describe the issues of traditional management control and we introduce an alternative control with non-financial ratios included, called the Balanced Scorecard. In the empirical data it is investigated how the governance of a municipality could be designed, according to the respondents. In the analysis the information gathered to reach the answers to what are considered to be useful governance in municipality, are examined. In the conclusion, we design Balanced Scorecards with both financial and non-financial ratios to the councils of the municipality..
Hantering av parasitproblematik på naturbetesmark
Värdet av att beta naturbetesmark är stort, både för den biologiska mångfalden men även för bevarandet av öppna kulturlandskap med stora rekreations- och kulturhistoriska värden. Då naturbeten är permanenta beten måste parasitsmitta av inälvsparasiter på betet förebyggas för att inte bli ett problem. Problem som kan orsakas av parasitangrepp är framför allt försämrad tillväxt hos djuren men även klinisk sjukdom såsom t.ex. diarré eller blodbrist. Förstagångsbetande individer är särskilt känsliga för parasitangrepp och måste därför skyddas från parasitsmitta i möjligaste mån.
Fossilfria godstransporter : En undersökning av alternativ till diesel som drivmedel för lastbilar
Our modern society is in many ways built with and dependent on fossil fuels, which are used for energy production as well as for transporting humans and goods. Without the oil, many of the things we take for granted would not be possible. During the last century, the use of oil has increased steadily and will probably keep increasing as the world population and the economic well-being for many people increase. Since the oil is a finite resource, we will have to find other fuels that can replace it if we want to keep the same rate of development in the future as the availability of petrol fuels will decrease with rising prices as a result. Furthermore, fossil fuels have the disadvantage that they produce harmful emissions when combusted and thus affect the climate and air quality locally and globally.

Digital doggy bag : iPhone applikation som tar med dina mat- och dryckupplevelser
In this project an iPhone application for storing food and drink experiences was developed with focus on an easy interaction design. The already existing market of similar applications were studied and evaluated to extract their positive and negative features. Interviews with experts within the food and drink business where made in the pre study to get a good perception of how to divide and categorize the sections in the application. To optimize the usability, workshops with potential users with different technical experiences where continuously held during the development of the design.During the development two variants of development environments where evaluated. The final result of the application was developed in the environment that made the best impression and seemed to be the best alternative.The resulting product has a thought out design meant to be easy to understand, even for the first time users.
Simulering av filtrerade skärmfärger
This report present a working model for simulation of what happens to colors displayed on screens when they are observed through optical filters. The results of the model can be used to visually, on one screen, simulate another screen with an applied optical filter. The model can also produce CIE color difference values for the simulated screen colors. The model is data driven and requires spectral measurements for at least the screen to be simulated and the physical filters that will be used. The model is divided into three separate modules or steps where each of the modules can be easily replaced by alternative implementations or solutions.
Den bristfälliga implementeringen av LSS en studie av maktaspekten i mötet mellan socialtjänsten och människor med psykiska funktionshinder
In this study, the aim is to show how the social services fails to implement a specific rights law (LSS) wich is supposed to have the function of protecting the wellfare and provide specific rights to people with severe mental disabilities. By applying chritical theory on this case the aim is to provide an alternative answer on why it is possible for the social services to ignore these peoples rights.By revealing the power structures in the encounter between the system and a person with mental dissablilities, I conclude that people with mental disabilities does not fit in when it comes the social sevices way of implementing the law and further more that a private person is extreamly exposed to the systems arbitrariness..
Förekomst av penicillinkänslighet hos blododlingsisolat av Staphylococcus aureus
Staphylococcus aureus is the most clinically important Staphylococcus species and is associated with high mortality in patients with positive blood cultures. S. aureus bacteria may cause a variety of disease manifestations ranging from minor skin infections to life-threatening conditions such as pneumonia, meningitis, osteomyelitis, endocarditis, toxic shock syndrome (TSS) and sepsis. This microorganism belonging to the gram positive cocci may also be part of the normal flora. In Sweden, penicillinase-stable penicillins are the primary alternatives to treat S.
Konstruktion av efterbehandlare
The purpose of this report is to examine various roof structures that can operate in a warehouse with large spans. The building that is examined in the report is currently under construction, and the roof construction has already been selected. The selected roof system will therefore be compared with some other structures and materials that have been possible. The report will evaluate three different frame materials, two insulating barriers and two overlaying materials. Another important part in major construction projects is the roof safety.
