The effect of pula devaluation on non-mining export sector in Botswana

This dissertation investigates the effects of exchange rate devaluation on non-mining exports in Botswana over the period 1984-2012 and the exchange rate pass-through effect to consumer prices. The economy of Botswana is significantly dependent on mineral exports, particularly the diamond. The dominance and over-reliance on diamond exports in the economy has led to low levels of economic diversification. Bank of Botswana has over the years devalued the pula, in attempt to stimulate growth of non-mining export industries and to enhance non-mining export competitiveness. However, raising export competitiveness this way may be inflationary and have no significant effect on non-mining exports. The study investigates the existence of cointegration between real effective exchange rate and the non-mining exports using the Johansen method of cointegration. The vector error correction model is used, to examine the short-run dynamics of the model. The results suggest that a positive long-run relationship exists between real effective exchange rate and Botswana’s non-mining exports. The results of the exchange rate pass-through suggest that nominal exchange rate has a short term relationship with consumer prices in Botswana. However this relationship does not hold over the long run

Ibuprofen, paracetamol and tilidine; their role in post tonsillectomy pain at Dr George Mukhari Hospital

Thesis (M Med(Otorhinolaryngology)) -- University of Limpopo, 2011.Background: Tonsillectomy is one of the commonest operations performed by ENT surgeons. Pain, haemorrhage, delayed feeding and resumption of normal activities are common morbidities. Different groups of analgesics are used to reduce these morbidities. Objective: We examined the effectiveness of the use of three analgesics, some in combinations in reducing these morbidities. The primary outcome measures were pain, resumption of normal diet, resumption of normal physical activities and secondary haemorrhage. The secondary outcome was comparison of pain profile of children and adults. Methods: A prospective randomized double blind controlled study. Subjects were recruited and randomized into three study groups; group A (Paracetamol & Ibuprofen), group B (Ibuprofen) and group C (Paracetamol, Ibuprofen & Tilidine). A diathermy dissection technique was used on all patients in removing tonsils. Pain was measured using a patient morbidity scoring form (PMS) as well as the Smiley scale. The care givers for children and adult patients recorded all other events. Results: Sixty five patients were recruited, 30 were in group A, 20 in group B and 15 in group C. There were 36 females and 29 males. The youngest patient was 4 years of age and the oldest was 38 years. The mean number of days prior to resuming normal daily activities for groups A, B and C was 9.27, 10.60 and 7.67 respectively. Group C patients started their daily activities earlier than those in group B (p≤0.05). The average number of days to stop analgesic use was 12.3, 13.3 and 10.6 for groups A, B and C respectively. Patients in group C stopped using analgesics earlier than group B patients (p≤0.05). There was no statistically significant difference in PMS scores, resumption of normal diet, post-tonsillectomy haemorrhage as well as pain profiles of adults and children. Conclusion: Paracetamol-ibuprofen-tilidine combination appears to be more effective than either paracetamol-ibuprofen combination or ibuprofen in the first two weeks in the treatment of post tonsillectomy pain (p>0.05), however, further studies will have to be carried out to confirm this. Patients treated with a paracetamol-ibuprofen-tilidine combination appear to stop medication and return to their normal daily activities much earlier (p ≤ 0.05). Minor haemorrhage from the use of ibuprofen following tonsillectomy was not a cause for concern

Characterization of Phase and Emulsion Behavior, Surfactant Retention, and Oil Recovery for Novel Alcohol Ethoxycarboxylate Surfactants

This semi-annual technical progress report describes work performed at Clark Atlanta University under DOE Grant No. DE-FG26-97FT97278 during the period October 01, 1997 to April 01, 1998 which covers the first six months of the project. During this reporting period, laboratory space to set up the surfactant characterization measurement system in the Research Science Center was made available. A Ph.D. student in Chemistry was identified and is supported as a Graduate Research Assistant in this project. Her contribution towards this project will form her Ph.D. thesis. The test matrix to perform salinity and temperature scans was established. Supply requests to obtain refined hydrocarbon, surfactant, and crude were processed and supplies obtained. A temperature bath with a control unit to perform temperature scans was obtained on loan from Federal Energy Technology Center, Morgantown, WV. The setting up of the temperature control unit, and associated chiller with water circulation lines is in progress. Tests were conducted on several hybrid surfactants to identify the best surfactants for future experimental work that yield almost equal volumes of top, middle, and bottom phases when mixed with oil and water. The student reviewed the current literature in the subject area, and modeling efforts that were established in previous studies to predict electrical conductivities and inversion phenomena. These activities resulted in one published conference paper, and one student poster paper during this reporting period

Trachoma in the Democratic Republic of the Congo: Results of 46 Baseline Prevalence Surveys Conducted with the Global Trachoma Mapping Project.

PURPOSE: Trachoma was suspected to be endemic in parts of the Democratic Republic of the Congo (DRC). We aimed to estimate prevalences of trachomatous inflammation-follicular (TF), trichiasis, and water and sanitation (WASH) indicators in suspected-endemic Health Zones. METHODS: A population-based prevalence survey was undertaken in each of 46 Health Zones across nine provinces of DRC, using Global Trachoma Mapping Project methods. A two-stage cluster random sampling design was used in each Health Zone, whereby 25 villages (clusters) and 30 households per cluster were sampled. Consenting eligible participants (children aged 1-9 years and adults aged ≥15 years) were examined for trachoma by GTMP-certified graders; households were assessed for access to WASH. RESULTS: A total of 32,758 households were surveyed, and 141,853 participants (98.2% of those enumerated) were examined for trachoma. Health Zone-level TF prevalence in 1-9-year-olds ranged from 1.9-41.6%. Among people aged ≥15 years, trichiasis prevalences ranged from 0.02-5.1% (95% CI 3.3-6.8). TF prevalence in 1-9-year-olds was ≥5% in 30 Health Zones, while trichiasis prevalence was ≥0.2% in 37 Health Zones. CONCLUSION: Trachoma is a public health problem in 39 of 46 Health Zones surveyed. To meet elimination targets, 37 Health Zones require expanded trichiasis surgery services while 30 health zones require antibiotics, facial cleanliness and environmental improvement interventions. Survey data suggest that trachoma is widespread: further surveys are warranted
