Infiltration capacity was measured with a double ring infiltrometer at 50 locations in two drainage basins in southern Zimbabwe. The infiltration capacity was tested against various factors recorded at each location to find relevant factors to use for mapping purposes. The factors recorded were land use, biotope, bedrock, landform, siteposition, ground cover, slope, aspect, organic content and tex
This is the result of a field study performed during July -September 1990 in Bakel, eastern Senegal. The village Bakel is in a semi-arid region with low agricultural productivity as a result of drought, degraded soils and excessive rainwater runoff. The thesis presents environmental conditions of the region and the water harvesting techniques introduced by a Swedish funded reforestation project. A
The purpose of the investigation was to explain the genesis of transverse ridges in the south Bolmen area, western Småland, south Sweden. A geomorphological map was made of an area with 39 transverse moraine ridges and a sedimentological study was carried out in one of them. The ridges were interpreted to be made out of mass movement till which was deposited supraglacially in troughs of a stagnant
The river of Bråån is heavely polluted by nutrient leakage from arable land. The aim of this study is to propose measures designed to reduce nutrient transport within the dranaige basin (165 km2). Leaking areas of the arable land were located and measures were suggested where they would be most effective. The west part of the basin tends to leak more through the soil profile as a result of very in
Climate and vegetation growth of an area are interrelated processes; both take place on small to global scales. However, climate change and variability impacts on vegetation in most places in the world including Tanzania is of great concern since vegetation supports many socio-economic sectors, and plays a crucial role in atmospheric greenhouse gas moderation. This study aims at investigating the
An objective method for calculating shelter effect of shelter belts - The projekt describes a method for objective classification of shelter effect for natural shelter belts. lt is aimed at producing a number of diagrams from which the shelter effect of a natural shelter, with a photographically determined porosity, can be predicted. Measurements of shelterbelt porosity has been made by analyzing
Popular science: Public transport plays an important role in enabling people to move from one place to another. The provision of information related to public transportation enables travelers to pre-plan their journeys and even save time that would have been spent asking around or looking for this information from other sources. The city of Nairobi has a population of about four million people, mo
As product life cycles continue to shorten, the importance of having an efficient innovation and product development process becomes increasingly important for any company operating in a competitive market. The company’s development process model, from the very first product planning phase in which a suitable portfolio of projects is created and maintained via the intermediary phases until the pro
It is well-known that the classical Poisson kernel for the unit disc $\D$ in the complex plane is naturally associated to the Laplacian. In this paper we establish a similar relationship between the kernel $$ P_2(z)=\frac{1}{2}\frac{(1-\lvert z\rvert^2)^3}{\lvert 1-z\rvert^4}, \quad z\in\D,$$ and a certain second order differential operator $D_2(z,\partial)$. The analysis of this relationship depe
The background to this thesis is the fact that high temperature during transport and storage, degrade the glucose of peritoneal dialysis fluid (PD-fluid), into a toxic substance. Research at Gambro has shown that exposure to high temperatures can destroy the PD-fluid in just a few hours, requiring months to repair. With this knowledge it became important to monitor the temperature, and evaluate wh
We investigate subalgebras of finite codimension in. In earlier work we have introduced a way of describing such subalgebras in terms of their so called (subalgebra) spectrum and a set of conditions for subalgebra membership that can be expressed by evaluating polynomials and their derivatives in points of the spectrum only. In this paper we focus on subalgebras with a single element in their spec
There is an increasing body of evidence, based on well-controlled clinical trials and long-term follow-up, that liposuction can result in significant objective and subjective benefit to patients who have long-term chronic primary or secondary lymphedema with long-term results. There are, however, different views on the immediate, short-, and long-term benefits of liposuction for treating lymphedem
