Cleaning process of abattoir wastewater with focus on bacterial pathogens

This study was conducted at the City Abattoir in Kampala, Uganda to evaluate the cleaning process, with focus on bacterial pathogens, in a pilot scale integrated bioprocess. This consisted of four steps: anaerobic sequencing batch reactors; aerobic/anoxic sequencing batch reactors; a high performance temperature controlled methanogenesis digester and a constructed wetland. The objective was to determine if this type of cleaning process could be used to clean wastewater from abattoirs in a satisfactory way. The indicator organisms for faecal contamination, Escherichia coli and Enterococcus spp. were used to investigate in what numbers bacteria could be found in the untreated wastewater and how much that was reduced in the different steps of the cleaning process. The water was analysed for Salmonella to see if human pathogens could be found and could survive the different steps of the treatment process.

Compost and its effects on soilborne plant pathogens

Certain microbial residents from composts are known to possess the ability to suppress soilborne plant pathogens. Trichoderma spp. and Gliocladium spp. are commonly found in composts and are perhaps the most wellknown hyperparasites of fungal pathogens, which may also be naturally present in compost. Trials have many times proven them to be effective against plant diseases caused by soilborne pathogens such as Pythium spp., Phytophthora spp.

Effektmätning i pump

The interest for power and energy measurement has greatly raised with todays increasing electricity prices and enviromental awareness. In the search for energy efficient solutions, the measurements are more complex due to increasing of non linear components. Harmonics and non sinusoidal voltages put high demands on sampling and filtering. Meanwhile, the price must be controlled so the customer still will find it interesting to invest in smaller plants. ITT W&WW asks for a robust, heat resistant power meter with compact dimensions to allow mounting inside the casing of a pump.

Löslighet och metylering av kvicksilver i en förorenad sjö (Ala-Lombolo) i Kiruna kommun :

Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. Our understanding of factors involved in the production of MeHg is very important for making a reliable risk assessment. The purposes of this study were to investigate the different factors that control the solubility of Hg and the production of MeHg in a contaminated lake sediment. The lake Ala-Lombolo, Kiruna municipality, is well-known to be contaminated by mercury from different sources. Sediment cores were sampled at three different locations (N, SW and SE) in the lake and divided in three different layers; 0-5, 5-10 and 10-15 cm.

Är silver en effektiv antimikrobiell substans? : En litteraturstudie om silver vid brännskadevård samt mot kateterinfektion. Vilken indikation är effektivast?

För att språket ska fungera normalt krävs ett samspel mellan uttrycksförmåga och förståelse av språk. Afasi är en språkstörning som kommer sig av en skada i de delar av hjärnan som påverkar språket. Att få afasi kan innebära en stor omställning i livet och ofta uppstår ett behov av anpassning av kommunikationen både för personen som fått afasi och personer i dess omgivning. Detta inkluderar även den vårdpersonal som arbetar nära personen med afasi. För att nå förståelse och kunna ge vård och omsorg av god kvalitet, måste tillräcklig kunskap om afasi finnas hos vårdpersonalen.

The bioavailability of soluble oxalates in stir-fried silver beet leaves

The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.

Vanliga helminter hos hund, katt och häst i Sverige : artbeskrivning och laboratoriediagnostik

This report includes common helminths, symtoms, routes of infection, diagnostic laboratory techniques and prophylactic methods to prevent infection. We have pointed out where there is a risk of zoonotic transmission and how to avoid contamination and infection. We have restricted the number of species to the most common helminths. Some of these helminths do not naturally occur in Sweden (yet) but are nevertheless of current interest when we travel across borders with our horses, dogs and cats. The diagnostic part of our report tells about different techniques to find an occurance of helminths in samples of faeces, blood, urine or saliva from a horse, dog or cat. We also write about some recommendations on treating parasitic infections and the development of anthelmintic resistant helminths that originates from incorrect use of anthelmintic drugs .

Att tala är silver men tiga är guld : En studie om journalisters syn på yttrandefrihet i irakiska Kurdistan

Tidigare forskning har visat att mediesituationen i Kurdistan är komplex och att medierna är politiserade. Syftet med denna studie är att belysa journalisters syn på deras yttrandefrihet i Kurdistan. Studien fokuserar på verksamma journalisters tankar kring yttrandefrihet, relationen med makthavare och tillgången till information.Kvalitativa forskningsintervjuer har tillämpats, med åtta yrkesverksamma kurdiska journalister bosatta i Kurdistan.Slutsatsen visar en komplexitet som är svår att synliggöra om man inte har förkunskaper i kurdisk politik och historia. Ramarna för yttrandefrihet skiljde sig helt från ramar som vi i västvärlden är vana vid. De åtta journalister som deltog i min studie hade varierande åsikter om yttrandefrihet..

Biological control of Fusarium wilt on tomatoes : use of Bacillus subtilis and interactions with the earthworm Pontoscolex corethrurus in a Kenyan highland soil

It is important to investigate the potential of biological control measures in agricul-ture, especially where economic issues restrict the use of expensive inputs or when there are environmental concerns about toxicity of agrochemicals. The bacterium Bacillus subtilis has proved promising as a biocontrol agent (BCA) in suppressing various plant diseases and it has also been shown to promote plant growth in certain cases. During this study, the effect of B. subtilis on Fusarium wilt (caused by the fungus Fusarium oxysporum) on tomatoes, as well as its effect on the earthworm species Pontoscolex corethrurus was investigated. Furthermore, the combined ef-fect of the BCA with P.
