The thesis addresses the instabilities in stock markets in the USA. There are many factors that may increase the price volatility, or even cause a panic. During these turbulent times investors can seek shelter in investment safe havens that allow protecting their portfolio against significant financial losses. The focus is put on identifying the situations where it is appropriate to use the safe havens and how to properly time all transactions. Historical insight, events study and investigating economic cycles are the integral part of the work.

It has long been known that companies can finance themselves with the help of equity or debt. Since Modigliani and Miller’s theories of capital structure and its impact on performance, several studies have continued to investigate the phenomenon of capital structure. Using previous research on capital structure as well as the irrelevance theory, trade-off theory and pecking order theory, researchers are constantly examining how capital structure affects companies, what affects the capital structure, and which financing is best suited for their specific company.This study intends to investigate how the capital structure is affected by companies’ profitability, growth, and economical cycle fluctuations in Sweden. The study examines Swedish companies listed on the Nasdaq Main Market Stockholm in the branch of industry, raw materials and real estate. The study sample consists of 109 companies that are examined over a ten-year period between 2010-2019. The study conducts regression analyzes of key ratios’ debt / equity ratios as a dependent variable, as well as ROE, ROA, profit margin, turnover growth, employment growth and GDP gaps as independent variables.The study concludes that cyclical fluctuations affect companies’ capital structure in the branch of industry. However, it could not be ensured that cyclical fluctuations affect companies in the raw materials industry or the real estate industry. The study measured that ROA correlates negatively with the capital structure of the branch of industry, as well as the real estate industry. Significance for the variable profitability measured with ROA could not be demonstrated. The variable ROE was only significant for the real estate, industry and positively correlated with the debt-equity ratio. Profit margin was significant and positively correlated for the branch of industry, and it was also identified that the profit margin was significant for the real estate industry, but the results were negligible. The same negligence was discovered for the significant variable for sales growth for the raw materials industry, while no significance was achieved for the branch of industry and the real estate industry. Finally, the variable employment growth was only significant for the real estate industry, where a positive correlation was shown with the debt-equity ratio. / Det är länge känt att företag kan finansiera sig med hjälp av eget kapital eller belåning.  Sedan Modigliani och Miller teorier om kapitalstruktur och dess påverkan på resultatet har flertal studier fortsatt undersökt fenomenet kapitalstruktur. Med hjälp av tidigare forskning om irrelevansteorin, trade-off teorin och pecking order teorin undersöker forskarna ständigt om hur kapitalstruktur påverkar företagen, vad som påverkar kapitalstrukturen, samt vilken finansieringsmetod som är bäst lämpad för sitt specifika företag.Denna studie avser att undersöka hur kapitalstrukturen påverkas av företagens lönsamhet, tillväxt, samt konjunktursvängningarna i Sverige. Studien undersöker svenska företag noterade på Nasdaq Main Market Stockholm i branscherna industri, råvaror och fastighet. Studiens urval består av 109 företag som undersöks under en tioårsperiod mellan 2010-2019. Studien genomför regressionsanalyser på nyckeltalen skuldsättningsgrad som beroende variabel, samt ROE, ROA, vinstmarginal, omsättningstillväxt, anställningstillväxt och BNP-gap som oberoende variabler.Studien kommer fram till att konjunktursvängningar påverkar företagens kapitalstruktur i industribranschen. Det kunde inte säkerställas att konjunktursvängningar påverkar företag i råvarubranschen eller fastighetsbranschen. Studien uppmätte att ROA korrelerar negativt med industri- och fastighetsbranschens kapitalstruktur. Det kunde inte uppvisas signifikans för lönsamhetsvariablerna för ROA. ROE var enbart signifikant för fastighetsbranschen och korrelerade positivt med skuldsättningsgraden. Vinstmarginal var signifikant och positiv korrelerade för industribranschen, det identifierades även att vinstmarginalen var signifikant för fastighetsbranschen, men resultat var försumbart. Samma försumbarhet upptäcktes för den signifikanta tillväxtvariabeln för omsättningstillväxt för råvarubranschen, medan det inte uppnåddes signifikans för industribranschen och fastighetsbranschen. Slutligen var tillväxtvariabeln för anställningstillväxt enbart signifikant för fastighetsbranschen där det uppvisades en positiv korrelation med skuldsättningsgraden.

Batteries based on lithium-sulfur technology have the potential to increase the amount of stored energy in comparison with current lithium-ion systems while maintaining the same weight. Achieving this goal is possible due to the high theoretical energy density of sulfur, which exceeds the values of other materials used in batteries. However, these batteries suffer from several failing, which still hinder the practical use. The use of amorphous sulfur instead of its crystalline form might lead to increasing of durability and charge efficiency. Inverse vulcanization of sulfur seems to be the perspective method for the preparation of polymer sulfur because it prevents its recrystallization and stabilizes amorphous sulfur. The aim of this thesis is the preparation and study of properties of materials made of inverse vulcanized sulfur.

This doctoral thesis deals with synthesis and characterisation of electroactive electrode materials for li-ion batteries and accumulators. The work is divided into two main parts. One deals with LiFePO4 based cathode composite electroactive material and in the second is described the synthesis and utilization of monoclinic TiO2(B) as an anode for li-ion cell. The main aim of the work is to relate the synthesis procedure and structural properties of both materials to its electrochemical preformance.

Hoy en día, las MYPES tienen un rol muy importante en todas las sociedades del mundo debido a su enorme potencial para desarrollarse, sin embargo, este sector presenta algunas limitaciones estructurales que limitan su sostenibilidad reduciendo su tasa de supervivencia. Esta situación las obliga a ser más flexibles y adaptarse rápida y eficientemente a los cambios del mercado. En este sentido, la presente investigación tiene como propósito analizar y demostrar la importancia de mantener los niveles de servicios óptimos dentro de una MYPE comercializadora de superalimentos que terceriza su proceso de producción, con el fin de evitar impactos económicos negativos que se encuentren vinculados a su proceso logístico. De la misma manera, se presenta una propuesta de mejora considerando los componentes de Gestión por Proceso y Políticas de Inventarios, las cuales son desarrolladas mediante las herramientas de BPM (Business Process Management), pronóstico de la demanda, stocks de seguridad e inventarios cíclicos. La aplicación integrada de estas herramientas permitirá incrementar la eficiencia de los procesos y el nivel de servicio evitando problemas como la entrega de pedidos incompletos, las cancelaciones por falta de stock y fallas en los productos; por ende, las pérdidas de ventas y pago de penalidades por incumplimiento. / Nowadays, MSEs play a very important role in all societies around the world due to their enormous potential for development; however, this sector has some structural limitations that limit its sustainability and reduce its survival rate. This situation forces them to be more flexible and to adapt quickly and efficiently to market changes. In this sense, the purpose of this research is to analyze and demonstrate the importance of maintaining optimal service levels within a superfood marketing MSE that outsources its production process, in order to avoid negative economic impacts that are linked to its logistics process. In the same way, an improvement proposal is presented considering the components of Process Management and Inventory Policies, which are developed through the tools of BPM (Business Process Management), demand forecasting, safety stocks and cyclic inventories. The integrated application of these tools will increase the efficiency of the processes and the level of service, avoiding problems such as the delivery of incomplete orders, cancellations due to lack of stock and product failures; therefore, the loss of sales and payment of penalties for noncompliance. / Trabajo de Suficiencia Profesional

This thesis investigates the emergence and establishment of an early public monitoring system of the Swedish economy prior to the First World War. The study relies on a careful examination of the source materials with the view to map why and how the monitoring of the Swedish economy emerged, who demanded it, how the public supervision of the economy was organised and administrated and the results of the efforts. The common driving force was an increasing political interest in Sweden and elsewhere over the labour issue towards the end of the nineteenth century. In fact, the establishment of the monitoring system of the Swedish economy was largely the result of a broader international statistical respons to the labour question by the end of that century. The emergence of a public monitoring of the economy was driven by a general need for measuring the effect of industrialisation on the labour market, especially the growing problems with episodes of involuntary unemployment in the industrialised countries towards the end of the century. The thesis is divided in two parts with a total of ten chapters. It is written within a traditional narrative structure, that is, the beginning, the middle and the end. The first part examines the emergence of the surveillance of the labour market and consists of three chapters according to the narrative structure covering the period 1893-1913. The second part consists of three chapters that investigate the establishment of a monthly economic survey of the Swedish economy between 1910 and 1914, structured in the same way as the part one. The establishment of this early public monitoring of the Swedish economy should be regarded as a forerunner of the National Institute of Economic Research (Konjunkturinstitutet) 1937.
