The hash economic conditions in Zimbabwe, marred with perpetual cash cri- sis, little to no foreign direct investments (FDI's), high unemployment rates, absence of the Central Bank roles and local currency has piqued my interests to study the long-run relationship of capital market indices and macroeco- nomic variables, in such conditions. The literature review analysed dierent research work that were done in health economics about the same subject but with dierent variable matrix structure and methods. Most of the stud- ies conrmed the short/ long-run relationship between capital market indices and macroeconomic variables. An ARDL method was employed on the subject matter, and interesting re- sults were obtained that are at variance with most of the existing empirical results in the literature. For example, most of the studies conrmed a signi- cant relationship between the exchange rate, interest rate and stock index but this research showed otherwise. Moreover, this work lled the existing gap in the literature on the relationship between the mining index and macroeco- nomics variables. Furthermore, it has been noted that consumer price index and exchange rates have a negative long-run relationship with the mining index. A way for further research of this nature in countries with the same or similar economic conditions as of Zimbabwe has been set in motion and needed for an abstract conclusions on the variations noted by this work.

Electrical power systems are vulnerable to contingencies due to the possibility of fault or damage. When a serious fault (which cannot be removed immediately) occurs in the power system, the fault needs to be isolated, and the remaining system should be reconfigured to make efficient use of available energy. Reconfiguring the system by making an island can be one of the strategies to continue the energy supply using the remaining generation capacity. By analyzing the effect of contingencies on power systems in terms of voltage support, reliability and stability, survivability of the system can be predicted. A survivability index of the system can be developed based on voltage support, reliability and the stability index with predefined weight given to each performance criterion. These weights may vary for different system conditions. The purpose of this research work is to develop a survivability index for shipboard power system and rank reconfiguration choices based on the developed index.

Bakgrund: Den tandrengörande trädpinnen Miswak tillverkas av Salvadora Persica träd och används i många länder i Afrika samt Asien. Sverige är idag ett multikulturellt samhälle där andel Miswakanvändare kan vara stor. Tandborstning med tandborste och fluortandkräm är en effektiv samt vanlig metod för tandrengöring i Sverige. Syfte: syftet med studien var att jämföra den plackreducerande effekten mellan Miswak och manuell tandborste med fluortandkräm. Metod: Studien var en klinisk crossover-prövning med Within-Subjects design som pågick under två veckor, där samma individer i en grupp medverkade i två olika behandlingar. Deltagare till studien valdes ut genom användning av enstegsklusterurval och de var första år tandhygieniststudenter som studerar på Hälsohögskolan, Jönköping University. Data insamlades i form av plackindex i procent genom användning av modifierat Plaque Control Record (PCR) enligt O' Leary/ Drake/ Naylor. Resultat: Plackindex på både individnivå och gruppnivå vid Miswakanvändning var mindre jämfört med tandborstanvändning. Användningsfrekvens med Miswak var också mindre än tandborsten under studieperioden. Det fanns ingen statistisk signifikant skillnad på plackreducering mellan manuell tandborste med fluortandkräm och Miswak. Slutsats: Miswak reducerade större plackmängden procentuellt under studieperioden jämfört med manuell tandborste med fluortandkräm men inga statistiska signifikanta skillnader kunde påvisas.
