Almens vara eller icke vara : om almsjukan och resistens
En frisk alm lever i fyra till femhundra år. Men smittas almen av den förödande almsjukan så kan trädet dö tillföljd av sjukdomen inom några månader. Almsjukan är en vissnesjukdom som orsakas av de två sporsäcksvamparna Ophiostoma ulmi och Ophiostoma novo ? ulmi. Sjukdomen sprids av almsplintborren eller via rotkontakt.
Från väpnad oppositionsgrupp till politiskt parti- En komparativ studie om transformeringen och institutionaliseringen av RENAMO, FRELIMO och SWAPO i Moçambique och Namibia
This thesis explores and compares the former armed opposition groups; Mozambique National Resistance (RENAMO), Front for the Liberation of Mozambique (FRELIMO) and South West Africa People's Organization (SWAPO) transformation processes into political parties. The first question addressed is; What factors determines the ability of these armed opposition groups to transform into political parties after armed conflict? The question is addressed through four structural and organizational factors; international involvement, the organizations ideology and identity, their ability to change inter-elite relationships and their ability to change collective incentive strategies. The second question addressed is if the transformations process can affect the parties? degree of institutionalization? The degree of institutionalization is examined through the party's adaptility, complexity, autonomy and coherence.
Prion infection of ovine cell culture with a natural Swedish scrapie isolate from 1986
Scrapie is an infectious neurologic disease in sheep caused by prions, corresponding to transmissible spongiform encephalopathies (TSEs) in other species. The prion is presumably constituted of PrPSc, the misfolded form of the normal endogenous prion protein, PrPC, which is found in practically all cells in the body. PrPSc can induce a conformational change in PrPC and misfold it as an imprint of itself; this is how prions amplify and spread. The process of conformational change is poorly understood and there might exist intermediate forms between PrPC and PrPSc. Bioassay using mice has traditionally been the golden standard in prion studies but is limited by cost and time.
Detection of mutations in dihydropteroate synthase (dhps) and dihydrofolate reductase (dhfr) in Plasmodium falciparum in eastern Sudan
ABSTRACT: Commercial swab transport systems are used for collection and transporting of fecal and other microbiological samples. This system must maintain viability and contribute to survival of microorganisms during transport to the laboratory. Four swab transport systems have been compared, eSwab, ?- Transwab and fecalSwab, all three with flocked swabs, and Copan Venturi Transystem with rayon swabs. The study followed the recommendations from the Clinical Laboratory Standard Institute; document M40-A for recovery of Samonella, Shigella, Yersinia and Neisseria gonorrhoeae after storage for 0, 6, 24, 48 and 72 h at room- (22-25°C) and refrigerated (2-8ºC) temperature.
ACL-rupturer hos fotbollstjejer ? riskfaktorer och prevention
Non-contact anterior cruciate ligament (ACL) injuries is a serius and traumatic injury to the knee that is common in female soccer players and often force the player to quit or lower the level of activity because of lost stability in the knee or from fear to suffer a new injury. Female soccerplayers have a higher risk than their male counterparts to get an ACL rupture and especially adolescent females have a high risk. The most common causes to a non-contact ACL rupture is side-cutting manuvers and landing after jumping. Every other player with an ACL rupture develops osteoarthritis within 10-15 years from the time of injuryResults: The higher risk for females to incur a ACL rupture is due to smaller intercondylar notch, they?re in the follicular or ovulatory phase of their menstrual cycle, increased knee laxity, dominance in the quadriceps muscles, flexion in hip and valgus movement in the knee.
Utökning av mätområdet för turbinverkningsgraden på avgasturbo
The Goal with this Master of Science thesis is to expand the possible turbine efficiencymeasurements on an exhaust turbocharger. It was done as a part of the CICERO competencecentre. To feed the turbine with air a special flow rig has been used. Instead of loading theturbine by just restricting the compressor flow a docking system for an electrical dynamometer isdesigned to use the dynamometer as an additional loading source. By using an electricaldynamometer as loading device for the turbine, measurements are not depending on compressorperformance.A large part of the work consists in designing accessories for the dynamometer.
Resistens mot ivermektin : vad vet vi idag?
Hypotyreoidism är en vanlig endokrin sjukdom hos hundar. Den orsakar nedsatt livskvalitet i form av utbredda symptom från flera olika organsystem och sjukdomen kräver livslång medicinering. En orsak till hypotyreoidism är Canine Lymphocytic Thyroiditis (CLT), en autoimmun sjukdom som står för ett stort antal av sjukdomsfallen hos hund. Mycket talar för att utvecklandet av sjukdomen har en ärftlighetskomponent eftersom den uppträder i mycket hög frekvens inom vissa raser medan det är en tämligen ovanlig åkomma inom andra raser. Studier av hundpopulationer har visat på en genetisk koppling mellan CLT och gener för Dog Leukocyte Antigen II (DLA II) hos vissa raser.
Effect of Bacillus mediated priming on different natural genetic variants of Arabidopsis thaliana
In two feeding experiments Bacillus induced priming of plant defense was tested for its effect against the generalist insect pest Spodoptera littoralis. The main hypothesis for the study was that Bacillus induced priming would enable the plant Arabidopsis thaliana to defend itself
better against this insect herbivore since this priming seems to involve jasmonic acid, known to be important for plant defense to insects. A secondary objective of the study was to examine if any differences in a primed defense capability could be seen between different natural genetic variants (ecotypes) of A. thaliana reflecting habitat differences in pest pressure.
The methods used for plant cultivation and Bacillus inoculation were aimed at reflecting conditions that can be expected in an agricultural cropping system. This meant that all plants were cultivated in soil, and the feeding experiments were conducted with the plants growing intact in the soil system.
Kortare sintid ? hur påverkar det kons mjölkavkastning, metabolism, hälsa, hull och vikt?
A shorter dry period length has in studies abroad showed some positive effects among high yielding dairy cows. Among other things it has been suggested that the periparturient metabolic stress becomes lower, that the fertility is improved and dry off becomes gentler for the udder, due to a lower milk yield. The milk yield is generally reduced during the first period after calving, especially among primiparous cows. The aim of this master thesis was to investigate how Swedish cows were affected by a shortened dry period, regarding milk yield, metabolism, health, body condition and body weight from two months before calving to some weeks after calving. Also plasma concentration of lactose during the period before calving was determined.
Bäst i klassen? : - En studie av hållbarhetsredovisningar i statligt ägda bolag
Due to the globalization and the changes in the market, companies have now realized the importance of a strong brand. This has led to the phenomena outsourcing. The relation between the branding consultant and his or her client has changed. Earlier the consultants worked as a single unit and were given a task to independently accomplish the assignment. Today there has to be co-operation between the two parties.
Grund plöjning med Kvernelands Ecomat och Ecomat Seeder : resultat från undersökningar genomförda år 2005
The Kverneland Ecomat and The Ecomat Seeder has been tested in three different field
studies. All the studies were conducted on soils with different clay content during 2005 in Säby outside Uppsala.
In one of the trial spring ploughing with the Ecomat and spring ploughing and seeding with
Ecomat Seeder were compared with conventional autumn mouldboard ploughing and spring
mouldboard ploughing to conventional depth (22-23 cm). In this study the quality of the
seedbed, the number of emerged plants and weeds, the pentration resistance and the yield
were examined.
Shallow spring ploughing (10 cm) with the Kverneland Ecomat has shown to be a good
alternative to conventional autumn ploughing when growing spring crops. During the season
2005 tilling with the Ecomat resulted in a higher yield than conventional ploughing. In 2002-2005 the average yield for shallow spring ploughing was 4 percent higher than after
conventional autumn mouldboard ploughing and 10 percent higher than after spring mouldboard ploughing to conventional depth (22-23 cm).
In the other two studies, ploughing to different depth in the autumn with the Ecomat was
compared with conventional mouldboard ploughing and stubble discing.
Kvantfysiken och den nya myten? : En studie av Fritjof Capras och Danah Zohars böcker om kvantandlighet
This study is about quantum physics and the role it can play in a religious perspective. I intend to examine how moderna physics may be related and understood as New age and Myths. My material consists of two books in the new age genre: "The Tao of Physics" by Fritjof Capra and "The Quantum Self" by Danah Zohar. My first two question to these books are which 1) religious and 2) scientific content they have. My other questions are too 3) investigate and demonstrate how these books are new age and 4) to exanine how the books can function as myths and adopt mythical features.
Animal welfare in Ethiopia : transport to and handling of cattle at markets in Addis Abeba and Ambo
Stressful routines for animal handling can reduce immune function and productivity of animals. If stakeholders are handling animals aversively, animals will show increased
expressions of fear for humans and higher stress levels which lead to the compromise of animals? welfare. In Ethiopia, there are no legislations to protect animals from suffering or discomfort. The main objective of this study was therefore to analyse welfare of cattle on animal markets in Ethiopia and map out supply chains of animals to these markets.
Hybridlärkens tillväxt i Snogeholm : hur påverkas produktionen i blandbestånd jämfört med trädslagsrena bestånd?
The hybrid larch (Larix x eurolepis Henry) is a fast growing tree species and was introduced in Sweden for about 50 years ago. The high growth and expected resistance to diseases are probably the main reasons of introducing the tree species into the Swedish forests.
The purpose of this thesis was to document the production of hybrid larch planted in the Snogeholm landscape laboratory and to compare the production in the pure hybrid larch stand with the mixture together with pedunculate oak (Quercus robur).
The data collection in Snogeholm since the establishment has been carried out by the Swedish University of Agricultural Science (SLU). The fieldwork for the thesis was carried out in 3 stands, containing hybrid larch, pedunculate oak and a mixture of hybrid larch and pedunculate oak, in order to be able to compare the total stand production of the areas.
The results show that the total production of hybrid larch in the mixed stand only is 35 % compared with the total production of hybrid larch in the pure stand. Therefore, the hypothesis that the total production of hybrid larch is equal to the planted mixture with pedunculate oak was rejected.
The other hypothesis that the total production of a 2 hectare large stand containing a mixture of hybrid larch and pedunculate oak would be greater than the total production of two pure stands of 1 hectare containing hybrid larch and oak each was also rejected. In the studied case the total production was 45 % greater if hybrid larch and pedunculate oak was planted in pure stands.
The results from the case-study only indicate that the total production of hybrid larch and oak under the investigated conditions can be higher when planting the two species in pure stands compared with a mixture of the two species.
Från könlös och avsexualiserad till sexuell och kåt : En intersektionell studie om sexualitet och funktionshinderskap utifrån ett cripteoretiskt perspektiv
Denna studie baseras på kvalitativa semistrukturerade djupintervjuer med personer med olika fysiska funktionsnedsättningar om deras upplevelser och erfarenheter om funktionsnedsättningar, sexualitet och genusgörande. Kategorin funktionsförmåga är i många diskurser omarkerade. I det icke uttalade om kroppars olika förmågor förväntas och blir en funktionsfungerande kropp norm. Min studie grundar sig på ett teoretiskt samarbete där Robert McRuer?s cripteori utgör referenspunkten.
