Microalgae reactors, commonly known as photobioreactors, have become increasingly popular as an alternative for wastewater treatment. These systems reduce pollutants and remove nutrients such as nitrogen and phosphorous compounds from wastewater utilizing microalgae and bacteria. The biomass produced in the reactors can potentially be used to produce biofuels and decrease some of the energy demands of the process. Wastewater treating photobioreactors are a relatively new technology and many aspects of their microbiology need further study. This thesis presents a broad overview of the algal and bacterial communities present in these systems by looking at the most important species, metabolic pathways and growth dynamics of both algae and bacteria. The experiments presented in this thesis were conducted using municipal wastewater from the Västerås wastewater treatment plant. The wastewater was inoculated with algae from Lake Mälaren and compared to non-inoculated reactors. Overall, the inoculated reactors demonstrated better algal growth than those that were not inoculated. The tested systems also removed much of the ammonium and phosphorous present in the wastewater. The dominant algae in the tested systems belonged to the genera Scenedesmus, Desmodesmus and Chlorella. In addition to algae, the systems contained a large number of bacteria, mostly from the phyla Proteobacteria and Bacteroidetes. The algal photobioreactors contained a lower abundance of genes related to nitrogen metabolism, virulence and antibiotic resistance compared to the initial wastewater, showing that a shift in the bacterial community had occurred. The bacteria found in the systems were shown to be involved in synthesis of vitamins essential for algae growth such as vitamin B12, suggesting cooperation between the bacteria and algae. / I takt med att världens befolkning ökar, så produceras dagligen allt mer avfall. Detta kan orsaka stora problem för miljön. När det byggs nya system för vattenrening behöver vi även ta hänsyn till kravet att minska energiåtgången. Dagens vattenreningssystem har vissa tillkortakommanden när det gäller reningsnivåer och energianvändning. Ett alternativ till dagens system, kan vara fotobioreaktorer, dvs. vattenrening med hjälp av mikroalger. Dessa system använder mikroalger och bakterier för att rena vattnet från föroreningar, kväve och fosfor. Vattenrening med fotobioreaktorer är en relativt ny teknik. Flera aspekter gällande biologin i dessa system har ännu inte studerats i detalj. Den här avhandlingen presenterar en översikt av de alger och bakterier som är aktiva i fotobioreaktorer. Andra viktiga aspekter som tillväxt, arter samt vattenreningsförmåga har också studerats. Ett antal försök genomfördes där alger från Mälaren tillsattes i vatten från Västerås kommunala vattenreningsanläggning. Storleken på försöken varierade mellan 250 ml och 20 liter. Det visade sig att algerna hade en bra tillväxt samt att mängden ammonium och fosfor minskade i vattnet under försöksperioden. De alger som tillväxte mest i studien tillhörde Scenedesmus, Desmodesmus och Chlorella. Förutom alger tillväxte även ett stort antal bakterier från grupperna Proteobacteria and Bacteroidetes. Dessa bakterier visade sig syntetisera viktiga vitaminer, t.ex. vitamin B12, som algerna normalt inte kan syntetisera själva. Sammanfattningsvis, så presenterar denna avhandling viktig information gällande alger och bakterier i en fotobioreaktor. Informationen kan vara ett viktigt bidrag till framtida utveckling av storskaliga fotobioreaktorer för vattenrening.

Thesis (MFamMed)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: Introduction: Diabetes is the most prevalent endocrinology problem encountered in primary care practice. If recent trends showing a dramatic increase in prevalence (believed to be a consequence of a decline in physical activity and excessive caloric intake) continue, then the condition will soon affect nearly 20 million people in the U.S a reflection of the global trend. Effective management requires care that is thoughtful and meticulous, incorporating intensive patient education. Euglycemic control, with the level of glycosylated haemoglobin (HbA1c) kept below 7.0mmol/L, has emerged as a major treatment objective because of its association with a marked reduction in the risk for micro vascular complications. The primary physician is in the unique position to provide comprehensive care to the diabetic patient. Setting: The aim of this study is to evaluate the profile of complications arising due to diabetes mellitus among adult diabetics attending internal medicine outpatient department and family medicine/primary care outpatient department in the Dora Nginza hospital, PE hospital complex. Method: The study is a descriptive retrospective study in which names of patients were collated from clinic records of both clinics, files sought at the records department covering the period between Jan 2007 and Jan 2008 inclusive. Prevalence of statistical variables was generated using frequency tables, bar graphs, cross tabulations and chi square test. Results: Hyperglycemia was the major complication which predominantly was associated with high haemoglobin A1c (HbA1c) levels. However, some hyperglycaemic cases were also found to be associated with normal HbA1c. Complications were found to be more in type 2 diabetics. Patients with hypertension, obesity, smoking and alcohol use were observed to have a higher risk of developing diabetic complications. The findings on retinopathy in this study was inconclusive in view of the fact that patients sent for fundoscopy did not return with documented results from the sister hospital PE provincial hospital. Family Medicine outpatient department overall did better in patient care compared to the Internal Medicine outpatient department. Conclusion: The challenge for the primary care physician is to design a therapeutic program that is safe practical and acceptable to the patient. The ultimate goal of therapy is the prevention of micro vascular and macro vascular complications, consequence of diabetes that makes the condition a major risk factor for cardiovascular disease, stroke, visual impairment, renal failure, impotence, peripheral neuropathy, limb loss and ultimately death. These can be averted through appropriate education of both hospital staff, patients and their care givers. The recommendations made are based on the findings of the study. / AFRIKAANSE OPSOMMING: Nie beskikbaar.

Objective. Measuring adherence levels and assessing the impact on adherence to ART (antiretroviral treatment) of the factors: disclosure to partner, partner support, other support and length of time between diagnosis and ART commencement, in a state-run ART clinic at Mitchells Plain Community Health centre. Design. A retrospective case control study was conducted and the information was obtained by means of a file audit. Methods. Every 5th file was selected for the study and 199 participants were chosen based on the inclusion and exclusion criteria. Adherence for each patient was measured using a formula documented in a published study. For the comparison group 82 cases (non-adherent patients) were matched for age and gender with 82 adherent controls. Results. The mean adherence for the initial group of 199 participants was 80.1%. Disclosure to a partner and partner support were not found to significantly affect adherence. The time between HIV diagnosis and ART commencement was also not found to make a statistically significant difference to adherence. There appeared to be an association, though not statistically significant, between other support (not from the partner) and >95% adherence (p= 0.0579). Conclusion. It can be concluded that adherence is probably influenced by a wide variety of factors. More qualitative studies or larger samples are recommended to better assess the impact of partner support and acceptance of HIV on adherence. Approaches to partner disclosure prior to commencing ART should be reviewed. The mean adherence level of 80.1% is an indication that more work is urgently needed to improve adherence levels in state-run clinics in South Africa.
