Orsaker till kolik hos häst
The aim of this work was to investigate possible risk factors for colic in horses, and to describe what horse owners can do to prevent this condition.
The gastrointestinal system of the horse is constructed for continuous high fibre consumption for a period up to eighteen hours a day. Under those conditions, the continuous flow of digesta stimulates gut motility so that the intestines move constantly. When the diet is changed rapidly and the horse is being fed high rations of concentrates each day, the risk of getting colic is higher compared to when consuming less concentrates and giving the horse a stable diet.
Lack or absence of access to water and restricted allowance to move freely every day increases the risk of colic. Changed management practices and decreased activity contributes to increased risks, as well as other critical risk factors such as breed, season and age combined with rapidly changed management.
More knowledge and education is required of the horse owners about feed requirements in the horse, management routines and rapidly changed activity..

Cultivation of Chlorella vulgaris in nutrient solution from greenhouse tomato production : a possibility to reduce nutrient levels and produce commercially interesting metabolites
The idea of using algae in different areas and exploring its possibilities is nothing new. Already in the early 1950s microalgae was explored as a possible food resource because of its high protein content. Lately there has been an increased interest in its potential for industrial use. Wastewater treatment is a possible use of algae since the algae grow well on the nutrients present in the water. This offers the possibility to grow algae for nutrient reduction and use the biomass for energy or animal feed since many alga species has a good nutritional value.
Approximately 800-1000 m3 water is applied per 1000 m2 of greenhouse area during one season in a tomato production.
Effekter av befintliga och eventuella framtida läkemedelsbehandlingar på morbiditet och mortalitet hos patienter med hjärtsvikt.
Background: Heart failure is a multidimensional phenomenon with high mortality. Heart failure is treated with angiotensin converting enzyme (ACE) - inhibitors or angiotensin receptor blockers (ARBs) that counteract neurohormonal stimuli that occur in heart failure, as well as providing vessel dilatation, which reduces symptoms and the need for hospitalization and increases survival. Despite this, only about 50% of heart failure patients survive 6 years after diagnosis with drug therapy, and as heart failure is increasing globally, due to improved care and treatment and increasing life expectancy of the population, there is a great need for new drugs such as LCZ696 that acts by dual inhibition of the renin - angiotensin - aldosterone system and neprilysin inhibition.Objective: The aim of this literature study was to evaluate the efficacy of current treatment and possible future treatments on mortality and morbidity in heart failure patients.Results: The examined articles show that treatment with ACE inhibitors in patients with symptomatic heart failure reduces the risk of total mortality by 16% over 3.5 years, reduces all-cause mortality or hospitalization due to heart failure with NNT (number needed to treat) = 10.4 over 3.5 years and increases median survival by 9.2 months over 12.1 years in patients with asymptomatic heart failure. Treatments with high-dose ACE inhibitors reduce mortality and hospitalization because of cardiovascular causes and hospitalizations from any cause by NNT = 30 over 3 years. Beta-blockers reduce sudden death and total mortality and cardiac death or non - fatal myocardial infarction with NNT = 38 and NNT = 23, respectively, over 12 months.
Kalvens beteende i olika uppfödningssystem :
The purpose of this literature review was to investigate how the rearing systems influence the behaviour of dairy calves. Calves are social animals that form groups within the herd where play and social licking between calves are important social activities. Suckling is a complex behaviour and essential for the calf's survival. In the modern rearing systems the calf is usually separated from its mother soon after birth. Calves are then kept in individual pens, group pens or, more rarely, with a foster cow.
The effect of rapeseed oil and palm oil supplement and milking frequency on milk yield and milk fat quality
Milk fat is an important feature in many different milk products and other foodstuffs and it is often crucial for the dairy plants that the milk fat is stable for different manufacturing processes. Lipolysis is the enzymatic degradation of fat and is the one of the causes for an elevated amount of free fatty acids (FFA) in milk. Further, the change in fatty acid (FA) composition in milk can affect the stability of the product and also the manufacturing process. Both internal and external factors, at farm level or at the dairy plants can affect both FA composition and content of FFA. Milking frequency (MF=number of milkings per cow and day) and the composition of feed are two examples of factors generally performed at farm level.
The objective of the present study was to evaluate how FA composition of milk and amount of FFA are influenced by two different ingredients supplemented to concentrate.
Utfodring i finmaskiga hönät : hästens ättid och skötarens arbetsmiljö
Horses are by nature herbivores, specialized on grass, and graze during the main part of the day. The horse has neither changed this basic behaviour nor the function of gastro-intestinal tract, when the horse was domesticated by man. A horse on pasture has an even production of saliva and gastric acids. The buffering effect of the saliva makes the pH in the stomach above four throughout most of the day. With abnormal long breaks of eating, the pH may decrease, causing an increased risk of gastric ulcer.
The effect of social rank on milking and feeding behaviour in automatic milking system for dairy cows
Today automatic milking systems (AMS) are growing in popularity. In these systems the cows are loose and have to get to the robot and the feed on their own. The cows ranking in this system affect their welfare. In this study data from seven years in an AMS was used and analysed. The aim was to investigate how ranking could affect the behaviour of the cows at milking and at feeding.
Motivation : en kvalitativ studie om elevers motivation i lärarledda lärandesituationer
Syftet med studien är att få en ökad kunskap om vad som motiverar elever i årskurs fem i lärarledda lärandesituationer. Valet att utföra studien i årskurs fem beror på att vi under vår studietid har mött elever i denna årskurs och har ställt oss undrande till vad det är som motiverar dem. Motivation är ett begrepp som har genomsyrat lärarutbildningen och på grund av detta ville vi veta mer om hur eleverna uppfattar begreppet. Flera teoretiker menar att elevers motivation till lärande kan påverkas av såväl inre som yttre faktorer samt diverse behov. Jenner (2004) anser att det även finns en tredje faktor där eleverna tycks pendla mellan faktorerna.
Tjänligt vatten i kranen - Membranteknik gör det möjligt : En utredning av pilotförsök i Glemmingebro
Nanofiltration is a proper way of preparation of drinking water. The process has a lot in common with reverse osmosis where a semipermeable membrane is used to separate a pure water flow from the remaining water. A pilot plant was used to ensure that nanofiltration is a suitable technology for a specific waterworks station in Glemmingebro, Ystad. The purpose was also to find out if a pH-adjustment is needed for feed water in a possible full scale plant. In this case nanofiltration is used mainly to remove sulphate and calcium since the raw water contains concentrations of these substances which exceed the limits for potable water. It is important to receive a high recovery (RC), otherwise the deliviery of water won?t be high enough.
Equine metabolic syndrome
Obese horses with insulin resistance are often also afflicted with laminitis. Horses with these symptoms are given the diagnosis equine metabolic syndrome (EMS). Signs of insulin resistance are excessive accumulation of adipose tissue on the neck, around the withers and on the dorsal area of the hindquarters. Insulin resistance means that the function of insulin is defective and does not stimulate glucose uptake by the cells in the body in the correct way. This will result in an increased insulin release.

Feedback eller feed forward. En fallstudie om feedback i matematik; hur den används och upplevs i en studieverkstad på Komvux.
Bedömning är en central del av lärares och elevers vardag och i den svenska skolan
tillämpas mål- och kriterierelaterad bedömning. Om bedömningen kan leda till mer än
bara ett betyg, och vägleda eleverna i deras sökande efter kunskap, sägs bedömningen
ha ett formativt syfte. En förutsättning för detta är effektiv feedback som kan hjälpa
eleven att jämföra sin prestation med kriterierna och själv engagera sig i handlingar som
leder till ökad kunskap. Syftet med detta arbete är, att som fallstudie, undersöka hur
feedback ges, upplevs och används i en studieverkstad i matematik på komvux.
Resultatet av observationerna visar att vanligt förekommande feedback var att lärarna
preciserade vad de studerande skulle förbättra eller att de gav beröm. Intervjuerna visar
att den feedback som ges uppfattas positivt av de studerande och de använder den
antingen för att korrigera fel eller som något som peppar och uppmuntrar dem.
Utvärdering av en beslutsåterkopplad kanalestimator för tredje generationens mobiltelefonisystem
This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).
Tungmetaller i metabolismen hos värphöns och slaktkycklingar
Mussel meal is a potential source of protein, with a good composition of amino acids, for laying hens and broiler chickens, and may replace the use of fish meal in organic poultry production. Lead and cadmium are heavy metals which occur in the environment and can be accumulated in mussels. When poultry are exposed to heavy metals, the metals are absorbed in the small intestine and distributed in the body in the form of ions, complexes or bound to proteins. In poultry, lead accumulates in bone tissue, liver and kidneys, while cadmium accumulates in liver and kidneys. Generally very low concentrations of these heavy metals occur in muscles of broilers which have been exposed to feed contaminated with cadmium or lead.
