The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.

Jällaskolans upper secondary School is situated on a big farm just outside Uppsala. The School is focused on agriculture, forestry, gardening, animal care and science. Jällaskolans staff has whished for a school garden for educational purpose where students can practice their gardening skills and learn more about plants. But most important, a specially adapted outside environment such as a garden, would be a great advantage for the students with special needs. This garden could even be an asset for other visiting school classes in the region.

Particular to the cat among our pets is its´ unique nutritional needs and metabolism. The cat cannot produce some nutrients by themselves and must get them through their diet. This means that the cat quickly can suffer from various diseases unless the nutritional needs are covered. In those cases where man is completely in control of the cat?s diet, the right knowledge is crucial for the cat?s wellbeing.

Pyometra is a common and life threatening disease of intact bitches. The disease is caused by a hormonal influence on the uterus in combination with a bacterial infection. The most common treatment is ovariohysterectomy, but several medical options are available to maintain fertility or avoid surgery and anaesthesia. Drugs that can be used for medical treatment are for example progesterone-receptor antagonists, prostaglandins and dopamine agonist. The present study focused on treatment with the progesterone-receptor antagonistaglepristone in combination with antimicrobial therapy.

Obesity is the most common nutritional disorder, and is defined as an accumulation of excessive amounts of adipose tissue in the body. Obesity is a condition where an animal exceeds its optimum body weight by more than 10-25%. Risk factors associated with obesity may include breed, age, castration or high energy intake relative to energy consumption. The consequences of obesity are believed to be metabolic and hormonal changes, as well as cardiovascular and respiratory diseases, orthopedic problems, tumors and premature death. Prevention and early detection of obesity leads to better health care.

Mindre än en timmes solsken på vår planet innehåller mer energi än hela världens energiförbrukning på ett helt år. Ett vanligt villatak i Sverige tar på ett år emot flera gånger mer energi än vad dess behov är. Potentialen för solenergi är mycket stor. Samtidigt använder samhället idag stora mängder energi och det mesta av energin kommer från icke-förnyelsebara källor. Sverige har visserligen en hög andel förnyelsebar energi jämfört med andra länder men ändå är mer än hälften av energin som vi använder icke förnyelsebar.Syftet med den här rapporten är att utveckla ett mer hållbart samhälle genom att använda solenergi.

Investment aid is a part of the Rural Area Programme, which contains support to Swedish agriculture and the countryside. There is a new programme every seventh year and SLU (Swedish University of Agriculture) has the mission to perform the evaluation of the previous programme, which lasted between 2000 -2006. The investment aid's aim is to support investments that, among other things, support the adaptation or conversion to more environmentally friendly production methods, improves the product quality, develops new or complementing activities, and improves the environment and the animal- and working environment. The question is if it's only money that matters for these kinds of investments to be done and what has happened with the money that was paid? This thesis investigates how the investment aid has affected the receivers.

Haemonchus contortus is the most important bloodsucking gastrointestinal nematode in small ruminants worldwide. It is often controlled by anthelmintics. Even though other methods to control are available, the most efficient way to treat an animal with clinically manifested haemonchosis is to use one of the available broad spectrum anthelmintics: benzimidazoles (BZ), macrocyclic lactones (ML) or imidothiazoles-tetrahydropyromidines or the narrow spectrum drugs salisylanilides or nitrophenols. Anthelmintic resistance (AR) against all groups of anthelmintics in nematode parasites has been reported from many countries, and even multiple AR has been observed. In this study I have investigated the resistance levels to all major classes of broad spectrum anthelmintics in a naturally infected flock of sheep of Red Maasai sheep (RM), Dorper sheep (D) and their offsprings on a research farm in Kenya.

As the world´s population increases and people's living conditions are improving, larger areas are needed for houses as well as food production. This means that new areas are exploited and that people, livestock, blood sucking insects and wild animals are forced to live close together. In combination with the global warming, leading to extreme weather such as floods and storms, this allows both new and old pathogens to emerge. The number of "emerging infectious diseases", EIDs, has increased in recent years and many of them have their origin in poor, tropical countries. Moçambique is therefore considered to be a high risk area for EIDs. Schmallenberg virus, SBV, was discovered in 2011 as an "emerging infectious disease" in dairy cows in Germany.

In the dairy production it is necessary to be able to sort cows. Dairy cows are sorted for many different reasons i.e. regrouping into production strings or for treatments i.e. inseminations, pregnancy and health checks, vaccinations or hoof trimmings. One labour saving way of conducting sorting is by using an automatic sort gate.

Cryptosporidium parvum is a protozoan parasite causing diarrhoea in many different animal species including cattle and man. It is an important enteric pathogen in neonatal calves and it is the second most common pathogen found in diarrhoeic calves in Sweden. Subclinically infected adult cattle have, in international studies, been shown to shed a low number of oocysts in faeces and this has been recognised as a potential source of infection for new-born calves. The detection methods used for diagnostic purposes are based on microscopic investigation of faecal smears. These methods have a fairly low sensitivity and samples from subclinically infected cattle have to be concentrated before analysis.

The agricultural sector has historically seen stable prices and a relatively constant demand for its products. Companies within the sector have generally had few loans and large sums of money tied in assets. The profitability of the companies has on the other hand been low. Together these circumstances have determined the creditors? demands on the companies within the sector and have formed the rules and regulations that exist today.

Healthy calves are the foundation in order to run a profitable diary production. Being healthy as calf results in a better start in life and good growth is expected to follow. Within dairy production it becomes more common to rear calves in groups and feed them by an automatic milk feeder. The milk feeder enables for the calves in greater extent to ingest milk or milk replacer several times per day and they are also able to perform natural behaviors in greater extent. Group rearing of calves puts higher demands on the animal keepers to localize individual calves in the group pen, showing signs of illness.

This project is a contribution in the debate of sustainable city planning. The conceptual ideas in this project can be used on many places and are here applyed on the center of Nacka, outside of Stockholm. The essay is based on an entry in the competition Europan 9, advertised by Europan in collaboration with the municipality of Nacka. The theme of the competition is ?sustainable city and public space?. The discussion of the sustainable city is a very wide subject which needs to be narrowed to suite the context of Nacka.
