Lomundal BK, Steinsbekk A
International Journal of Chronic Obstructive Pulmonary Disease , 2012, DOI: http://dx.doi.org/10.2147/COPD.S27352
Abstract: r follow-up of a one-year self-management program for patients with COPD Original Research (3330) Total Article Views Authors: Lomundal BK, Steinsbekk A Published Date February 2012 Volume 2012:7 Pages 87 - 93 DOI: http://dx.doi.org/10.2147/COPD.S27352 Received: 15 October 2011 Accepted: 19 December 2011 Published: 09 February 2012 Borghild K Lomundal1,2, Aslak Steinsbekk1,2 1Department of Public Health and General Practice, Norwegian University of Science and Technology (NTNU), Trondheim, Norway; 2St Olavs Hospital, Trondheim, Norway Objective: Investigate long-term effects 4 years after the end of a 1-year self-management program (SMP) with 30 hours of education and 16 hours of physical activity in patients with chronic obstructive pulmonary disease (COPD). Methods: Prospective observational outcome study. SMP focused on improving disease related self-care skills. Main outcome measures were health-related quality of life, HRQoL, (St Georges Respiratory Questionnaire, SGRQ total) and exercise capacity (6-minute walk test, 6MWT). Results: Thirty patients participated, 47% women. Baseline mean age was 67 years and mean pre-bronchodilator FEV1 (forced expiratory volume in 1 second) percentage predicted was 41.3. HRQoL showed a statistical significant improvement during the 1-year intervention. Four years after the end of the program SGRQ total was similar to baseline value, 1.4 points (95% CI: –3.6 to 6.3, P = 0.580). Also 6MWT was similar to baseline value at the same test point, –10 m (95% CI: –27 to 8, P = 0.262), and 63% reported having continued to exercise regularly a minimum of three times per week during the follow-up period. Conclusion: The participants in a 1-year self-management program with additional training had maintained their pre-intervention level of HRQoL and exercise capacity 4 years after the end of the program. Two out of three participants had continued to exercise regularly.

From Local Conflicts to Global Terrorism: Can Refugees and Regional Security Problems Jeopardise the Renewal of Kenya?
BK Chacha
African Journal of International Affairs , 2004,
Abstract: Over the last decade or so the African continent has continued to experience political changes of monumental proportions. Monumental not only because of the drastic restructuring of social and economic and political spaces, but also because of the introduction of new forms of politics and political actors. These changes were driven a great deal by the developments in the global system, in particular, the demise of the Soviet Union as a nation and super power, the triumph of the market, and more importantly, the end of the Cold War. In relation to these changes, the African continent has equally been characterised by a succession of large-scale refugee movements, internal population displacements and mass repatriation movements. In a number of countries – Angola, Burundi, Liberia, the Democratic Republic of the Congo (DRC), Rwanda, Sierra Leone and Somalia, for example, large proportions of the population have been uprooted, forced to abandon their homes by communal and ethnic conflict, persecution and violence. Most of these refugees have ended up in Kenya with a number of arms or religious fundamental ideologies. The process has witnessed an influx of arms in Kenya, helping fuel intra-ethnic and inter-border conflicts. Kenya has witnessed massive devastating terrorist attacks beginning with the bombings of the US Embassy and now Kenya has become an easy prey and target for terrorist activities. The reasons for this trend have been a concern for academics around the globe. A close look at intra-state conflicts in East Africa reveals a common pattern, for example: rebellion against central authority; inter-communal ethnic or religious conflicts; sporadic short lived conflicts related to resource around livestock; and generalised violence which is banditry-related. This study is a historical investigation of the development of local conflicts, informal militia and security measures during the transition to political pluralism in Kenya between 1992-2002, and tries to establish some links that may have connected or caused the country to be a target of international terrorism.
Amylase activity of a yellow pigmented bacterium isolated from cassava waste
BK Saliu
African Journal of Biotechnology , 2009,
Abstract: This study investigated the amylase activity of a yellow pigmented bacterium isolated from cassava wastes obtained from a dumpsite near a gari processing factory in Ibadan, Nigeria. Isolate was grown in nutrient broth containing 1% starch and then centrifuged at 5,000 rpm. Amylase activity was assayed using the DNSA method for the detection of reducing sugar. Best enzyme activity was recorded at 30oC and pH 7.5. The amylase was found to be stable after exposure to temperatures between 20 and 40oC and pH 6.0 to 9.0, outside which there was a decline in activity. The ability of the isolate to produce amylase explains its colonization of a cassava waste dumpsite. Conditions of activity and stability also agree with the growth condition of the isolate.
Dehalogenation and decolorization of wheat strawbased bleachery effluents by Penicillium camemberti
BK Taseli
African Journal of Biotechnology , 2007,
Abstract: This paper examined the capability of Penicillium camemberti to dechlorinate and decolorize wheat straw-based pulping and bleaching effluents. In batch tests, the highest removals for CEH (Chlorination-Extraction-Hypochlorite) bleaching sequence [65% organic halides (AOX) 84% color] were obtained with 2 g/l acetate concentration in 10 days under non-shaking conditions. Experiments in shaking flasks containing Tween 80 produced 60% AOX, 79% color removals in 10 days. This removal efficiency was also in accord with gas chromatography analysis indicating drastic reductions at low molecular weight adsorbable organic halogen compounds.

African Journal of Biotechnology , 2008,
Abstract: This paper examined the ability of Penicillium camemberti to degrade hemp-based pulp and paper plant bleachery effluents in batch and up-flow column reactor studies. In batch tests, the highest removals for acid-line effluents (67% AOX (adsorbable organic halogens), 44% TOC 8 total organic carbon), 97% color) were obtained with 2 g/l acetate concentration in 10 days. Acid-line and alkali-line composite effluent was also fed to a column reactor with of 17 mg/l. AOX concentration. In column studies, the highest removals (57% AOX, 67% TOC, and 74% color) and (57% AOX, 48% TOC and 73% color) were obtained with 0.5 and 0.2 g/l feed acetate concentration in 20 days, respectively. Gas chromatography analysis indicated drastic reductions at low molecular weight adsorbable organic halogen compounds.
Effects of computers on creativity of art students
BK Dogbe
Journal of Science and Technology (Ghana) , 2004,
Abstract: This study was made to investigate the effects of the use of computers by the Art students of the Kwame Nkrumah University of Science and Technology (KNUST) in Kumasi on their creativity in art productions. A total of 200 art students of the fourth year were involved in the study. The instrument consisted of a 20-item Likert scale questionnaire designed and validated by the researcher to elicit the desired responses from the students. The elements of creativity that were investigated included among others, the computer's ability or otherwise to surpass humans in creative art productions in terms of speed, flexibility, versatility, precision, capacity, efficiency and aesthetics. The responses of the questionnaires were coded. The mean and Standard deviations of the responses were calculated. The responses were later correlated through the use of the Pearson correlation formula. Computer was used in processing all data. The results showed varied intercorrelation. The views of the respondents showed a positive stance, which the researcher believes, arose out of enough experience or exposure to computers and their potentials. Based on these results a conclusion was made. Journal of Science and Technology Vol.24(2) 2004:84-91

Groundwater quality in the Wassa West District of the Western Region of Ghana
BK Kortatsi
West African Journal of Applied Ecology , 2007,
Abstract: Reconnaissance hydrochemical survey of 56 wells was conducted in the Wassa West District with the objective of providing baseline data for the establishment of groundwater quality monitoring stations. The data acquired is used in this paper to assess the quality of groundwater in the District. Groundwaters are mainly mildly aggressive with pH values in the range 4.5–6.9. However, a few of the boreholes show strong acidic character (pH range 3.7–4.0). The conductivity values are in the range 37–780 mS cm-1 with a mean 246.4 mS cm-1 suggesting the groundwaters are generally fresh and have short residence time. The groundwaters are moderately hard to very hard with only 40% of the samples representing soft waters. Groundwater quality is excellent with respect to major ions (Ca2+, Mg2+, Na+, HCO3 -, SO4 2-, Cl-) as they fall below their respective WHO guideline limits for water potability. Uncharacteristic of mining areas, trace metals loading of the groundwaters are generally low. All except aluminum, arsenic, barium, iron, manganese, mercury and nickel have concentrations well below the WHO guideline limits for water potability. Aluminum (0.0–2.5 mg l-1), iron (0.0–18.3 mg l-1) and manganese (0.0–2.41 mg l-1) are higher than WHO guideline limits of 0.2 mg l-1, 0.3 mg l-1 and 0.5 mg l-1 in more than 20%, 40% and 25% of the wells, respectively, and, therefore, pose significant aesthetic quality problems to groundwater quality. Mercury concentration exceeds the WHO guideline limit of 0.001 mg l-1 in all the wells during the rainy season and, thus, poses the greatest physiological threat for groundwater usage for drinking purposes in the District. Arsenic and barium exceeded the WHO guideline limit in less than 5% of the wells. Aesthetic problems can be eliminated using iron removal plants or aerators. These will induce the co-precipitation of trace metals with ferric oxyhydroxide. Limiting mercury usage in mining will curtail physiological problems.
