Licht: snel en toch traag

Licht: snel en toch traag

Licht … snel? 300 000 km/s lijkt waanzinnig snel, maar eigenlijk is dat niet zo. Computers van vandaag rekenen bijzonder snel en voeren enkele miljarden berekeningen uit per seconde. Dat wil zeggen dat computers meer dan 1 berekening uitvoeren per nanoseconde. Hoe ver propageert licht op die tijdsschaal? 30 cm! 0 10 20 30 De lichtsnelheid meten op een tafel met de methode van Foucault De opstelling van Foucault is een ingenieus ontworpen afbeeldingssysteem dat een puntbron afbeeldt op een detector (camera). Het licht wordt eerst naar een snel roterende spiegel gestuurd en wordt daar gereflecteerd. Op een zekere afstand L staat een spiegel die het licht opnieuw richting snel roterende spiegel stuurt en vervolgens dezelfde weg terug volgt. Tenslotte wordt het licht afgeleid naar een detector. Wanneer de roterende spiegel snel genoeg roteert, verschuift de afbeelding. Uit de verschuiving, de afstand L en de rotatiesnelheid van de spiegel kan de lichtsnelheid berekend worden. Δx Roterende Spiegel w De snelheid van het licht wordt gedefinieerd als c = 299792,458 km/s en is een basisgro...

Objectives To describe the dairy production and marketing systems in Jimma and to identify constraints for dairy marketing and development in the area Milk Production and Marketing system in Jimma Town, South-western Ethiopia Tadele Tolosa1, Mulugeta Tefera1, Yosef Deneke1, Abebaw Gashaw1, Karlien Supré2 and Sarne De Vliegher2 1Jimma University, College of Agriculture and Veterinary Medicine, Department of Microbiology and Veterinary Public Health, P. O. Box 307, Jimma, Ethiopia 2Faculty of Veterinary Medicine, University of Ghent, Department of Reproduction, Obstetrics and Herd Health, Merelbeke, Belgium Materials and Methods Jimma is found in Oromia Regional State, located at 352 km south west of the capital, Addis Ababa. A total of 47 smallholder dairy farmers and 51 dairy milk retailers were interviewed using pre- structured questionnaires. The questionnaire captured household demography; cattle herd sizes and composition, milk outlets and milk production aspects for smallholder dairy farmers. The data collected in the study was stored in Microsoft Excel and descriptive statistics was employed to summarize the data. Conclusions Dairy production is the domain of men rather than women. Most of the producers run dairy production as supplementary income. Farmers use natural mating for breeding purpose and use of artificial insemination is farmers’ quest. Milk reaches to the consumers by indirect routes resulting in a quality reduction and increase i...

. 4. Result: 78 woody species were recorded in the fragments. The most frequent species were Croton macrostachyus Hochst. ex Delile and Syzygium guineense DC. occurring in 50 and 44 % of the plots respectively. Dominance of Croton macrostachyus indicates high level of forest disturbance. Six plant communities were identified from the Indicator Species Analysis (ISA), i.e. Croton macrostachyus, Albzia schimperiana, Albizia gummifera, Syzygium-Olea welwitischii, Prunus-Polyscias and Schefflera-Rhus. Diversity indices for each community given in table 1. From NMS two main groups were identified: (i) the Croton, Albzia schimperiana and Albizia gummifera communities in the semi-forest coffee plantations at Geruke and Fetche and (ii) the Syzygium-Olea welwitischii, Prunus-Polyscias and Schefflera-Rhus communities in the forest and semi-forest coffee in the continuous forest at Gera (Fig 1a&b). Management intensity and distance from Jimma explained the major differences in species composition in the two groups (Fig.2). 3. METHODOLOGY: 91 sample plots of 20 m x 20 m were laid in coffee forest fragments in Geruke, Feche and Gera, (Jima Zone) with different size and varying level of coffee management practices. Data on vegetation, edaphic and anthropogenic disturbances were collected from each plots. Indicator species analysis was used to determine the optimal number of groups in the cluster analysis. Diversity indices were calculated for each community. NMDS was used t...

V/BOTANICAL DIVERSITY OF POTENTIAL FORAGE PLANTS IN RANGE AND FARMING SYSTEMS OF GILGEL GIBE CATCHMENT/JIMMA ZONE: A total of 135 forage plant species comprising of 58 families were identified. Asteraceae, Fabaceae and Poaceae are the major forage plant families of the region comprising 31% the forage plant species (P<0.05). Herbaceous plants consist of 61% of total collections and widely grown in open areas, cultivated lands and water banks. Brachiaria, Cynodon, Sporobolus, Pennisetum and Setaria are abundant genera of grasses in road sides and grazing areas whereas the wetland regions are densely colonized by Cyperaceae species The farmers’ traditional measures against pasture shortage was more to rent grazingland and purchase roughages and concentrates, than reducing stock, which is a more used strategy in medium highlands, and might thus also contribute to the higher incidence of cattle deaths in lower altitude regions .These preliminary results suggest that not only browsing herbivores, but also grazers on tannin-rich vegetation can have adaptive mechanisms to tannins. Chemical analysis of the IFTS is a first step in evaluating their nutritional value, but data on digestibility and conservation strategies have to be added. Yet, the nutrient concentrations already suggest that IFTS have a clear potential for being used as feed resources that can maintain normal ruminal function. Plant species identification is a first step in evaluating potential fodder plants, but da...
Remediation of environmental pollution in Jimma town, Ethiopia, caused by wastewater discharge through development of low cost onsite treatment systems

Remediation of environmental pollution in Jimma town, Ethiopia, caused by wastewater discharge through development of low cost onsite treatment systems

This is PhD work done in the context of the IUC-JU project. Contacts: PhD: alemayehu.haddis@ju.edu.et; a_had12@yahoo.com supervisor: Bart.VanderBruggen@cit.kuleuven.be; Ilse.smets@cit.kuleuven.be Alemayehu Haddis Promoters: Bart Van der Bruggen, Ilse Smets: KU leuven, Belgium Introduction Waste water treatment in developing countries should be simple, affordable and effective. Current conventional technologies for wastewater treatment, such as activated sludge and tertiary nutrient removal are too costly to provide a satisfactory solution for the increasing wastewater problems in developing regions. This research is designed to analyze and quantify the extent of pollution loading on the Awetu – Boye- Gilgel Gibe river basin and develop small scale cost effective and efficient method of waste water treatment system in Ethiopia that foster sustainable use of water resources. Constructed wetlands seem to be a promising solution to point sources of pollution and this project will assess remediation possibilities by experimenting SSFCWs and SSF as potential technologies. Objectives Make baseline survey and map point sources of pollution along the Awetu-Kito drainage basin in Jimma Town Quantify and characterize Jimma University wastewater Evaluate existing wastewater treatment systems in Jimma and Ethiopia Develop and test the efficiency of Subsurface Flow Constructed Wetlands (SFCWs) and Slow Sand Filters (SSFs) Modeling and optimization for the removal of BOD, N...

Janssens2 1Department of Animal Science, Jimma University, Jimma, Ethiopia; 2Laboratory of Animal Nutrition, Ghent University, Merelbeke, Belgium; 3Department of Reproduction, Obstetrics and Herd Health, Ghent University, Merelbeke, Belgium Discussion Material and Methods Results and Discussion Introduction References Milk production was on average low (Table 1) Fat and protein content of the milk was less than that reported by Fekadu and Michalak, 1988; Zinash et al., 1988) for crossbred cows around Holeta and Addis Ababa The SCC ranged from 142 to 3154 per µl on a farm basis. Prevalence of subclinical mastitis based on SCC was 71.15% Plasma Cu concentrations were on average below the threshold for deficiency (Table 2). Kincaid (1999) indicated that marginal deficiency of plasma copper is 0.7 to 0.9µ/ml and it is considered adequate when the level is 0.9 to 1.1 A positive correlation was found between SCC and milk production (r = 0.782). Plasma Cu and geometric SCC average per farm were negatively correlated (r = -0.691). This suggests that Cu deficiency increased the susceptibility of dairy cattle for mastitis k -Mastitis is a serious disease of dairy animals causing great economic losses due to reduction in milk yield, as well as lowering its nutritive value (Allore, 1993). - In Ethiopia, bovine mastitis is one of the most frequently encountered diseases of dairy cows (Le...
