Vanvårdens inverkan på nötkreaturs välfärd och hälsa
Farmers are required to make sure that cattles basic needs are met, but still every year cases of neglect occur where the farmer has not complied within the animal welfare law and regulations. The aim of this study was to investigate how cattle are affected physically and behaviourally by neglect in the form of underfeeding, starvation and lack of sanitation, which animals are most vulnerable to the impact and what prospects they have to recover. The study was conducted as a literature study and the results show that these types of neglect have a large impact on the cattle welfare. Underfeeding and starvation causes physical changes leading to reduced milk production, reduced muscle mass, impaired immune function, poor reproductive performance and changes in rumen microflora leading to decreased number of microbes and pH change. Physical changes due to the lack of sanitation consist of increased vulnerability to hoof diseases and mastitis, burns, and increased sensitivity to temperature.
Functional Cuts
Our everyday life is becoming more active and the activities we perform influence the way we dress. Due to an increase in activities undertaken in an urban environment, demands are changing and the need for active wear that meets the new demands follow suit. The four characters represented in the research can be seen as a reflection of the functional features needed, including base layer, mid layer/insulation and shell.Despite the increase in activities, most of our clothes are still constructed on static dummies or drafted on a table in 2D and the main developments within the active sportswear field is driven by material innovation. By creating garments on a body in movement, my aim is to develop new functions and expression in active sportswear through construction.Construction methods in active sportswear are examined and understood through observations and reconstructions and constitute the foundation of a study of movement for a design recovery.The movement and features required for leading an active urban life sets the direction of the development of new func- tional garments. A series of trial and error sessions and draping fabric on a live model in movement created the prototypes used in functionality tests to establish their feasibility.
Effekt av sönderdelningsgrad och planteringsdjup på uppkomsten från rhizom av Tussilago farfara :
Tussilago farfara, coltsfoot, is a troublesome perennial weed with deep lying rhizome, which can vegetatively generate new plants. The mechanical control of coltsfoot that is used today, "starvation", which consists of several cultivations of the soil, which fragmentises the rhizome. This results in production of new shoots, which leads to depletion of nutrient resources; as long the new plant is not allowed to establish. However, very little research has been done to investigate how the starving technique affects the regenerative ability of coltsfoot. The purpose of this experiment with coltsfoot was to investigate how fragmentation and burial depths affect the time of emergence, number of emerged shoots per rhizome fragment, number of shoots per node, and if the germination ability within nodes changes during the experiment.
Intensiv lästräning
Det övergripande syftet med vår studie är att undersöka hur intensiv lästräning under en sexveckorsperiod kan påverka ordavkodningsförmågan samt ta del av elevernas upplevelser av det arbetet. Våra frågeställningar är: I vilken utsträckning utvecklas elevernas ordavkodningsförmåga under sexveckors intensiv lästräning? Hur upplever eleverna det intensiva tidsbegränsade insatserna? Vilka tendenser kan vi se beroende på om eleverna genomför intensiv lästräning individuellt eller i liten grupp? I vilken utsträckning utvecklas de elever som också låg under TIL:s gränsvärde, men som inte genomförde intensiv lästräning? Mycket av tankarna inom intensiv lästräning återfinns inom den sociokulturella teorin där inlärning sker i samspel med någon annan, samt inom elevens proximala utvecklingszon. Vår studie har både kvalitativ och kvantitativ forskningsansats, eftersom vi har genomfört halvstrukturerade elevintervjuer samt tagit del av testresultat. Resultatet visar efter genomgången intensiv lästräning att samtliga elever ökat sin ordavkodningsförmåga samt stärkt sin självkänsla som läsare.
Hur bör unga hundar av storvuxna raser utfodras?
The dog is unique in the way that the adult weight can vary 100 folds between the different breeds. Despite this, most of the breeds reach adult size before two years of age. For the large-breed dogs this means a very rapid growth when some of them can have a weight gain of up to 150 times their birth weight. The most rapid growth occurs when the puppies are between three to six months old and that kind of rapid growth during such a short period of time makes these large-breed puppies very sensitive to deficits and excesses of energy, nutrients and minerals. Some examples can be excess of energy, excess or deficit of minerals such as calcium and phosphorus or deficits of protein.
The rapid growth can also make the large-breed puppies predisposed to some diseases affecting the skeletal and joints.
Fosforavskiljning i reaktiva filter vid småskalig avloppsrening
An excessive input of nutrients to lakes and other water bodies has created a problem with eutrophication in Sweden. Untreated, or partially treated, domestic sewage is a major source for discharge of phosphorus (P), which is the nutrient most frequently responsible for eutrophication of most fresh waters and the Baltic Sea. The waste water can be cleaned by filter materials, which have a high P-retention ability and which after saturation may be used as fertilizers. Four potentially suitable filter materials were tested in batch- and column experiments in this study. In the batch experiments, the following materials were shaken with waste water in time series ranging from 5 seconds to 60 minutes: coarse (1-4 mm) and fine (0-2 mm) Polonite® (heated bedrock from Poland); Filtralite® (light expanded clay aggregates with limestone added before burning); water cooled blast furnace slag (BF-slag) and BF-slag mixed with 10% burned limestone.
Utveckling av en beräkningsmodell för biogasproduktion
A growing interest for the climate and the environment has led to an increased interest forenvironmentally friendly and renewable energy sources, such as biogas. Planning new biogasplants requires a decision basis including facts about approximate amounts of biogas possibleto produce at the plant. The purpose of this thesis is to develop a model that calculates theapproximate biogas and digestate production from a planned or existing biogas plant.Developing the model required a literature review and studies of calculations concerningbiogas and digestate production performed by WSP Sweden AB. As a complement to themodel development, facts about substrates for biogas production were compiled through aliterature review. In addition the methane potential from selected materials was determined bybatch experiments.
Upplevd kvalitet i kundservice : En kvalitativ undersökning på en prisfokuserad marknad
SammanfattningSyftet med denna uppsats är att skapa djupare förståelse för kvalitetsbegreppet i en tjänsteleverantörs kundservice. Uppsatsen utreder även hur kvalitetsbegreppet skiljer sig åt beroende på varför kunden kontaktar kundservice. På grund av tjänsters abstrakta natur blir kvalitet i dessa sammanhang svårt att definiera. När tjänsten dessutom är av homogen karaktär, som exempelvis för en elleverantör, hamnar fokus ofta på pris. Detta kan bero på att det är det enklaste sättet att differentiera sig från konkurrenters erbjudande, speciellt när kvalitetsbegreppet är abstrakt.

Är kolrika jordar en källa till fosforläckage? : en sammanställning av data från 130 åkerjordar
Phosphorus (P) is an essential nutrient but a surplus could lead to eutrophication. Furthermore,
the minerals used to produce the mineral phosphate is a non renewable resource.
There are in other words several reasons to reduce the leakage of P and the agriculture is one important area to attend. The aim of this work has been to investigate if carbon-rich arable soils content contain more P than arable soils with low carbon content. Moreover it has been calculated if the carbon-rich soils could pose a risk of P leakage by comparing their delivery of P with the plant uptake. The work has consisted of compiling the results from former gathered and analysed soil samples of 130 Swedish arable soils.
The fractions of P considered are water soluble P (Pw), ammonium lactate-extractable P (P-AL), hydrochloric acid-soluble P (P-HCl), organic ammonium lactate-extractable P (Porg-AL) and inorganic ammonium lactate-extractable P (Porg-HCl).
