Molecular testing of raspberry plants infected with tomato black ring virus
Nematode-transmitted plant viruses (such as nepoviruses) cause great economically losses in commercially important plants such as tomatoes, grapevines and raspberries all over the world. To avoid spread of the viruses the interest in mapping the viruses has increased. One of the important nepoviruses infecting European red raspberries (Rubus idaeus) is Tomato black ring virus (TBRV). TBRV has earlier been confirmed in raspberry samples from Belarus by ELISA and the aim of this bachelor degree project was to confirm these results by amplifying, cloning and sequencing the coat protein (CP) gene of the virus. In total eight viral cDNA samples, from two different raspberry samples, were amplified and sequenced.
Optimisation of a method for isolation of Clostridium difficile from faeces
Clostridium difficile is a pathogen for both humans and animals and is often associated with antibiotic-associated diarrhea. Recently, several human cases of C. difficile-infection with increased mortality and morbidity have been reported. In studies performed in different countries C. difficile has been found in meat.
Hållbarhetsstrategier: Är det ett hinder att vara mindre? ? En studie kring motiv bakom implementering av hållbarhetsstrategier i mindre svenska företag inom hudvårdsbranschen
Problem: Small companies dominate the skin care industry, and they also face moredifficulties, constraints and resistance in strategy implementation and sustainabilitywork than other operators. Still, the trend of sustainability strategies increasesignificantly precisely in this industry.Purpose: The purpose of the study is to contribute knowledge to the field ofsustainability strategies and motives for the implementation of them in smallercompanies who engage with skin care, in Sweden.Framing of a question: Why do some smaller Swedish companies in the skin careindustry choose to implement sustainability strategies in their business?Literature: The literature functions as a framework for the study and is considered toidentify the possible reasons why small companies choose to implement sustainabilitystrategies or not. The literature is collected before the empirical data.Method: This paper is constructed by a qualitative method approach. The empiricaldata were collected through interviews, by telephone, personal meetings and email,which were then transcribed and the interpreted by a model, which the authors havecreated.Conclusion: Smaller companies are often met by larger resistance and an until up tothe present slowly emerging industry with vague rules and controls as well as ancomparative knowledge of what is good and what is not.
Parasite detection in extensively hold Gotland ponies
Horses are herbivores that spend almost all day grazing. While grazing they are infected by different endoparasites through ingestion of infective eggs or larvae on pasture. The most significant equine endoparasites in Sweden are the equine roundworm Parascaris equorum, small (Cyathostominae) and large strongyles (Strongylus spp), the tapeworm Anoplocephala perfoliata and the pinworm Oxyuris equi. For many years have horses been dewormed on regularly basis, which has resulted in the development of resistance to many anthelmintic classes. Because of the problems with resistance it is since 2007 necessary to have a prescription on anthelmintics and faecal sampling is also recommended.
Djup icke vändande bearbetning i sockerbetsodling :
A field experiment was carried out in 2006 to investigate the effects of deep rotary cultivation on sugarbeet growth. The background to the experiment was a 2005 study showing potentially higher yield, higher cleanness and higher sugar content when primary tillage was carried out to 35 cm depth with a rotary cultivator.
On four field sites in Skåne (L:a Isie, Ädelholm, Stävie and Vragerup), five different
treatments were compared: mouldboard ploughing in the autumn to 20 cm; mouldboard
ploughing in the autumn to 20 cm + rotary cultivation in the spring to 35 cm; rotary
cultivation in the autumn to 35 cm; rotary cultivation in the spring to 35 cm; and mouldboard ploughing in the spring to 20 cm.
The rotary cultivator used in the treatments is manufactured by a Dutch company, Imants. The implement cultivates the soil with spade tines fitted on arms that are mounted on a horizontal rotating PTO-driven axle.
Beet plants were inspected and yield determined in the experiment, and three soil parameters were examined: penetration resistance, water infiltration and infiltration of blue dye. Root shape was also examined.
The site at Stävie was not harvested due to poor beet establishment. At the other sites, the highest yield was found when the soil was rotary-cultivated in the autumn.
Kloning av möjlig promotorsekvens uppströms kloritdismutas i Ideonella dechloratans.
Perchlorate and chlorate are naturally occurring in the atmosphere, from here it sediments into groundwater and soil. The pollution is increased by discharges of perchlorate and chlorate from agriculture and paper mills. Bacteria capable of reducing perchlorate and chlorate to chloride and oxygen can be used to get rid of these contaminants. However an anaerobic environment needs to be sustained in order for this reaction to be used. For this reduction to work in an aerobic environment as well, a greater knowledge of the reducing enzymes, regulating factors and their corresponding genes is needed.

Koppar på drift
In my project, Cups on the run, I have studied the relationship between ceramic utility objects and different environments, when moving them off the table. My background as a potter has been the starting point. From there, I wanted to see if I could expand my craft to the space beyond. With the cup, which for most people has a clear function and a relation to us human, in repetitive structure I explored the spatiality and architecture in various environments. Life fascinates me through how everything is made up of tiny parts that together create the tangible and intangible.
Prevalence of subclinical mastitis and udder pathogens in small holder dairy farms in Mapepe, Batoka and Choma areas in Zambia
Subclinical mastitis (SCM) is a well-known problem in the dairy sector, where it causes severe economic losses mainly due to reduced milk production. This is a problem not only in the western world but also in developing countries. Surveys from different developing countries have shown a SCM prevalence of 52.4 ? 88.6 % at cow level and 26.7 ? 63.2 % at quarter-level. To combat mastitis is important to optimize the milk production of the cow.
Missuppfattningar inom genetiken: En litteraturstudie om hur missuppfattningar inom genetiken hos h?gstadie- och gymnasieelever kan motverkas
In schools, misconceptions about genetics can arise due to several factors, and the consequences of
these misunderstandings can be significant. Lack of education can play a central role in the spread of
misinformation about genetics. When teachers lack sufficient knowledge or do not have access to
up-to-date resources, they risk inadvertently conveying inaccuracies to students. Additionally, students
own preconceived notions and misinterpretations can be reinforced through interaction with their
peers, creating a vicious cycle of misinformation.
In this study, various misconceptions within genetics education have been identified and analyzed,
while different strategies to prevent these misconceptions have been examined. The study revealed that
the two most common misconceptions are the confusion between "genes" and "DNA" and the
simplified perception of genetic determinism.
Medkämpe i arbetarklassens stora befrielsekamp : Föreställningar om klass, kön och skötsamhet i tidningen Arbetets Kvinnor 1927-1931
This is a study of the trade union journal for female blue collar women in Sweden, Arbetets Kvinnor, between 1927 and 1931. The purpose is to examine how a female trade union activist's constructs collective identity by those notions of social class, sex, and moral values that are articulated in the journal. The main theoretical basis is Alberto Melucci's analysis where he argues that a collective identity in social movements is made in an interaction between individuals, where the action possibilities and limits are defined. Another purpose is how the female blue collar worker's resistance and/or adaption to the male hegemonic trade union and the bourgeoisie hegemonic society are presented. The essay shows how the collective identity is made of both historical and contemporary images of the working class women as workers and trade union activists.
Arvets betydelse för mjölkkors beteende :
It becomes more important to consider different behaviour traits in the selection for dairy cows to be suitable in the production systems of today. The purpose of this investigation was to study the genetic background to behavioural traits and the heritabilities for temperament, rank order, aggressiveness, feeding behaviour and for learning behaviour. Moreover, the genetic correlations to other traits were studied. To be included in a breeding programme a trait needs to have enough genetic variation, a moderate to high heritability or to be correlated to another measurable trait. Behaviour is a quantitative trait affected by many genes and the environment.
Motsättningar i det harmoniska samhällets gryning: En studie av sambandet mellan rule of law och rättmätigt motstånd i Folkrepubliken Kina
År 1999 infördes principen om rule of law i Folkrepubliken Kinas konstitution - lagen skulle styra landet. De år av vanstyre som nådde sin kulmen under kulturrevolutionen hade åsidosatt lag och ordning och hade lett till att Folkrepubliken Kina vid tiden för Deng Xiaopings maktövertagande i slutet av 1970-talet stod utan ett rättssystem. Vid sidan om den ekonomiska reform som skulle öppna upp landet för världen gjordes därför enorma insatser för att etablera ett fungerande rättssystem. De kinesiska medborgarna fick många nya lagstadgade rättigheter, men på många håll runt om på den vidsträckta kinesiska landsbygden tillämpades lagarna inte till fullo av lokala styren som skaffade sig förmåner genom att inte tillämpa alla rättigheter. Bland de människor som inte fick ta del av rättigheterna formades rättmätigt motstånd ("rightful resistance") - motstånd med stöd av lag - som riktades mot illojala kadrar på lokal nivå.Sedan dess har rättmätigt motstånd ökat och är en aktuell fråga i dagens Kina.

Occurrence of Verotoxin-encoding phages in mussels grown downstream the sewage treatment plant in Lysekil
The purpose of this study was to investigate the occurrence of Verotoxin-encoding bacteriophages in mussels, cultured downstream the sewage treatment plant in Lysekil.Mussels were collected in three growing areas from April 2008 to March 2009. Real-time PCR was performed for detection of vtx1 and vtx2 genes and enrichment of bacteriophages on non Verotoxin-producing Escherichia coli O157: H7 was carried out. All samples in real-time PCR analysis were negative; no presence of Verotoxin-encoding phages was shown. No plaque was formed on blood agar base plates, indicating that no bacteriophages had been taken up by E. coli bacteriaThe levels of Verotoxin-encoding phages and E.coli outside the sewage treatment plant in Lysekil were not high enough to be able to form VTEC in mussels, indicating that the faecal contamination was low.
