Implementation av ett digitalt vågfilter på en SIC-struktur

When implementing syncronous filters with global clock nets, a substantial amount of energy is consumed in the clock net. Hence, it is interesting to reduce the size of the clock net, which in turn will reduce the total energy consumption. One way to acheive this, is to create a SIC (Structured Interfacing of Computational elements) since such a structure can be created without a global clock net. Our results show that a fifth order wavedigital filter with a sample rate of at least 10M samples/sec may be achieved.

Utvärdering av den biologiska reningen av processavloppsvattnet vid GE Healthcare i Uppsala

GE Healthcare operates in Uppsala (Sweden) and develops systems, equipments and medium to purify medical substances. Discussions with the local authority concerning planed far-reaching changes and upgrades of the biological process techniques for sewage management, aroused the question about revising the terms of permit for the activity. Therefore it seemed necessary to evaluate a newly installed biological process technique, which is the background of this thesis. The evaluated biological treatment process was built in 2003 and consists of a biological reactor filled with moving bed carriers with a high surface area for biological growth. At the time of the project the biological wastewater treatment plant consisted of a flow equalization facility and two following parallel biological processes; a biological reactor with moving bed carriers and a tower trickling filter.The aim of this thesis was to survey the function of the biological reactor with respect to the reduction of organic matter.

Effects of treatment with PiNO (Pulsed Inhaled Nitric-Oxide) on the metabolism in colic horses undergoing abdominal surgery.

The main objective of this research was to study how increased arterial oxygenation by the use of Pulsed Inhaled Nitric-Oxide (PiNO) influenced the metabolic and cardiovascular parameters on horses undergoing acute abdominal surgery because of colic. The parameters blood lactate, blood glucose, pH and heart rate were evaluated before and during anesthesia and closely after recovery. The study showed that blood lactate concentrations decreased significantly during anaesthesia in horses treated with PiNO compared to non-treated horses. It was also seen that the lactate concentration decreased most in horses with the highest levels before PiNO treatment. Since enhanced oxygen extraction ratio was evident in the PiNO group, improved oxygen delivery to the tissue may be a possible explanation for the improved situation.

Dubbelkönighet hos mört : normalt eller miljöinducerat?

A number of chemical agents, and their degradation products, have been recognized as having estrogenic activity on animals. On fish they interfere with endogenous estrogen and in many cases mimic its activity, thus increase estrogenic reponse, with elevated levels of vitellogenin. Hence they are called Endocrine Disrupting Chemicals, EDCs. Vitellogenin levels is often used as a biomarker of exposure to estrogenic pollutants. Wastewater from sewage treatment works contains chemicals known as EDCs, and there are evidence of roach (Rutilus rutilus) living in recipients of such wastewater having traits of both gender, i.e. oocytes in male gonads (intersex) on histological examination. This study was done on roach living in Lake Funbosjön Uppland, Sweden.

Utomhusgym, några fördelar? : En studie om affekter vid styrketräning inomhus respektive utomhus

PurposeThe aim of the study was to examine the affects perceived by young people aged 18-19 years old after resistance training outdoors versus resistance training indoor. The aim of the study was also to examine if the rate of perceived exertion was affected by whether the resistance training took place outdoors or indoors. What immediate affects are perceived in conjunction with resistance training outdoors and indoors in people aged 18-19 years?What immediate affects are perceived after resistance training outdoors compared to equivalent resistance training indoor in people aged 18-19 years?What perceived exertion level can be seen in conjunction with resistance training outdoors compared to equivalent resistance training indoors in people aged 18-19 years?How does exercise habit correlate with affects and exertion in conjunction with resistance training? Method22 pupils in a secondary school conducted two resistance training sessions, one outdoors and one indoor. A questionnaire about their mood and exercise habits was answered before and immediately after the training session. Rate of perceived exertion rate was also included in the questionnaire the participants received after the workout.

Vallfoder till slaktgrisar : effekter på tillväxt och social beteende vid utfodring

The aims with the project were to investigate how forage consumption affect production and pigs behaviour around the feeding. This degree project was designed to follow 48 growing/finishing Hampshire*Yorkshire pigs, from 30-110 kg live weight, fed diets with or without 20 % forage inclusion. The pigs were divided in three groups due to dietary treatment. In the first group the pigs were fed 20 % of the energy in the feed ration by long grass/clover silage (LE) and the remaining 80 % by a cereal concentrate. Group two was fed chopped grass/clover silage mixed with cereal concentrate (HE) in the same amounts as LE.

Dutch Disease and Tourism - The Case of Thailand

Tourism is often being viewed as one of the worlds largest sectors and a great contribution to growth and development. There is a large motivation amongst developing countries to promote themselves as a tourist destination, since they expect the tourism to generate economic growth. The government of Thailand has been promoting tourism since 1960, and the number of foreign visitors has increased from 100 000 back then to 13.5 million in 2006. The purpose of this paper was to investigate weather the increasing tourism industry in Thailand has pulled resources away from other sectors of the economy towards the tourism sector, and in that way harming Thailand?s international competitiveness and causing deindustrialization.

Fysiologi och beteende hos golden retriever i hemmiljö och under en testsituation

To fit into our society the dogs of today need a good mentality. To investigate their mentalitydifferent behavior tests have been developed. The tests are useful tools in the selection ofbreeding animals as well as for working and companion dogs. To counter the demand for atest that could be suited for all kind of dogs, regardless of their future function, the mentalitytest Beteende- och personlighetsbeskrivning hund (BPH) was developed. BPH consists ofseven subtests that expose dogs to various situations that can be found in everyday life, suchas meeting an unfamiliar person, sudden noises and suddenly appearing objects.The aim of this study was to find out if there are differences in physiological values betweenindividuals, validate the behavior observations during BPH and get aware of how the dogsexperience the situation.

Artificiell Insemination (AI) hos hund : en sammanställning över användandet av seminering inom hundaveln i Sverige under åren 1995-2004

The use of artificial insemination (A.I.) as an alternative to normal mating in dog breeding in Sweden are controlled by regulations from the Swedish Board of Agriculture and by ethical rules assigned by the Swedish Kennel Club. Only veterinarians, who have a specific certificate and are specially trained and educated, are allowed to perform inseminations in dogs. Each artificial insemination must be documented and reported to the Swedish Kennel Club (SKK) which, on the behalf of the Swedish Board of Agriculture, yearly presents statistics concerning the use of A.I. in Sweden. The objective of this study was to illustrate the use of artificial insemination in dog breeding in Sweden for the last decade, using the yearly reports from the Kennel Club during the period of 1995 to 2004.

Förekomst av meticillinresistenta Staphylococcus spp. på kirurgiskt behandlade hundar

Surgical site infections are a recurrent problem in veterinary medicine. A 2-5 % infection rate in clean surgery has been reported. During the last years the increase in methicillin resistant staphylococci has also taken its toll on veterinary medicine, demanding a stricter hygiene and antibiotic regime. The 2008 outbreak of methicillin resistant Staphylococcus aureus (MRSA) at the University animal hospital, Swedish University of Agriculture indicated that that the MRSA problem was now a real, possibly zoonotic problem.Since the first dog, in Sweden, was diagnosed as a carrier of methicillin resistant Staphylococcus pseudintermedius (MRSP) in a study in 2006, the infection rate by this bacterium has increased. In 2009 (January 1st - December 2nd) the National Veterinary Institute (SVA) has identified 58 samples as MRSP positive.

Större och mindre växtätares samexistens : Möjlig interaktion och effekt på lokal biodiversitet

The purpose of this report was to investigate to which extent local presence of large herbivore mammals (Alces alces, Cervus elaphus, Capreolus capreolus, Dama dama and Sus scrofa) covaries with small rodents (Myodes glaerolus, Apodemus flavicollis and Apodemus sylvaticus? The hypothesis was that high abundance of wild ungulates would inhibit the density of small forest rodents. The data was collected during field work within FoMA (Environmental Monitoring Assessment)/SLU (Swedish University of Agricultural Science). The Ungulate dropping inventory and rodent trappings, which is the base in this report, where performed 2012 ? 2014 in Gnesta/Nyköping municipalities (G/N) with a relatively high density of wild ungulates and Vetlanda/Växjö municipalities (V/V) with relatively lower wild ungulate density.
