The water crisis in Gaborone : investigating the underlying factors resulting in the ‘failure’ of the Gaborone Dam, Botswana

Torka är mycket vanligt i Botswana. I huvudstaden Gaborone har Gaboronedammen klassats som ett misslyckande eftersom vattennivån har sjunkit till under sex procent av den potentiella volymen under 2014. Det finns inte någon officiell enighet om vad som har orsakat denna extrema volymminskning. Vattenbrist kan ha negativa konsekvenser för ett lands ekonomi, utveckling och till och med för den natioBotswana is an arid country endemic to drought. The major water supply in the capital Gaborone, the Gaborone Reservoir, has received a failed status early this year due to diminishing water levels which have fallen below six percent of the total potential volume in 2014. However, there seems to be no official consensus as to what has caused this extreme decrease in volume. Water scarcity can have

Carbonatites at the Alnö Complex, Sweden and along the East African Rift : a literature review

Carbonatite is an unusual type of rock that, for a long time, were not accepted for what they really are. This group of rocks is now considered to be of igneous origin and is classified after its content of carbonate minerals. If it exceed 50% the rock will be named a carbonatite. This group of rocks can be found all over the world and two of these places, which this review will focus on, are the

Idylliska landsbygden och stora stygga staden - En jämförande studie av medierapportering kring sociala problem på landsbygden och i tätort

The aim of this study was to examine how social problems are described and constructed in the printed press from two different regions in the south of Sweden; the rural municipality of Svalöv and the densely populated city Malmö. The study was based on news articles from the printed newspaper with the biggest daily circulation, from the respective areas. Articles relating to a predetermined array

Theory and numerics of phase field models for solidification of binary alloys

The phase field method emerged as a tool to solve free boundary problems with a sharp interface. In previous methods, this involved the computationally inefficient and complicated tracking of a moving interface. The phase field method overcomes this limitation by introducing an auxiliary variable called the order parameter which varies continuously over the whole domain and takes on finite values

Fish on drugs - an experimental study of crucian carp exposed to fluoxetine and a natural predator

Organismer i våra sjöar och hav måste ständigt kämpa för sin överlevnad i en miljö fylld av olika stressande faktorer, inte minst till följd av mänsklig påverkan. I en laboratoriestudie har jag undersökt hur den vanliga sötvattensfisken ruda (Carassius carassius) störs av två olika faktorer som misstänks påverka fiskars välmående – exponering för en anti-depressiv medicin (fluoxetin) och risken föOrganisms in the aquatic environment face the challenge of exposure to environmental pollution by a multitude of pharmaceuticals. However, the potential for disruptive effects in non-target aquatic organism remains poorly understood. Fluoxetine is one of the most commonly prescribed psychoactive drugs and it has been shown to bioaccumulate in fish, and potentially affects a broad suite of importan

Heme degradation pathway controls inflammation in model of mouse prostatitis

Dödliga gasen kolmonoxid – behandling mot prostatacancer? Kolmonoxid är för de flesta människor känd som en gas som kan orsaka förgiftning och snabbt leda till döden. Små doser av kolmonoxid har dock upptäckts kunna motverka inflammation. Många forskare är övertygade om att kolmonoxid inom en snar framtid skulle kunna användas som läkemedel mot bland annat kronisk tarminflammation. Ett hopp har oAcute or chronic inflammation in the prostate is implicated in pathogenesis of benign prostate hyperplasia (BPH) as well as development of prostatic intraepithelial neoplasia (PIN) and prostate cancer (PCa). Chronic prostatitis (inflammation in the prostate) is associated with high morbidity and negatively impacts life quality. Macrophages are critical regulators of inflammatory processes and are

Complexity Reduction in the CORDIC Algorithm by using MUXes

Nowadays, the CORDIC algorithm plays an important role to deal with the non-linear functions in hardware. In this thesis, a novel methodology is described to reduce the complexity in an unrolled CORDIC architecture, which gives higher speed, lesser area, and lower power consumption. That is, MUXes are used to replace adder stages. Five different unrolled CORDIC architectures have been implemented

Svensk fastighetsreglering - reglernas syfte och användning

Fastighetsbildningslagen (FBL) antogs 1970 och ersatte ett tiotal lagar gällande fastighetsbildningsåtgärder. Bestämmelserna kom nu att samlas och bli mer översiktliga. Ett nytt fastighetsbildningsinstitut som instiftades var fastighetsreglering. Detta institut skulle ersätta ägoutbytena som fanns i den äldre lagstiftningen. Tanken med ägoutbyte var att kunna utföra ömsesidiga byten av relativt smThe Swedish real estate law was adopted in 1970 and replacing the many existing laws regarding real estate measures. This lead to a better overview. A new real estate institute was about to take shape, which was to replace the old institute of change of land areas. The new institute, property reformation institute, was to be similar to the old one with the aim of exchanging small areas of land bet
