Background: Testosterone is the most important androgenic hormone in the male. Aging is closely associated with reduction of serum testosterone which can lead to reduced muscle mass, muscle strength, bone density, and depression. These symptoms may be counteracted by administration of testosterone. Objective: The purpose of this study was to examine the effects of hormone replacement in men with age-related testosterone deficiency. Method: We performed a systematic review using Randomised Controlled Trials (RCT).

We have conducted a case study on Trelleborg AB to examine how entrepreneurial the company is. We used a model called "entrepreneurial orientation (EO) with five dimensions that should be considered when striving to be entrepreneurial. The goal of being entrepreneurial in this thesis is achieving organic growth. The contingency of the case company determines the generalizability of the finding..

Topping is a precommercial thinning (PCT) method where secondary stems are cut higher above the ground compared to conventional PCT. The secondary stems continue to live for a period and are supposed to compete with the main stems and promote their quality.The objective of the study was to compare the effect of PCT on height and diameter growth between topping and conventional PCT. The study also analysed the relationship between height and diameter growth and the number of stems after PCT.Nine topped stands and six conventional precommercially thinned stands were visited between February 28th and March 5. One sample plot per hectare was laid out in the investigated stands. In every sample plot the number of stems was counted and five main stems were measured for height, height growth since PCT, diameter and diameter growth since PCT.The results showed significantly higher effect on height growth after topping as compared to conventional PCT but no significant difference in the effect of diameter growth between topping and conventional PCT.

Common wisdom dictates that because payment of dividends decreases funds available for investment, a high payout ratio is to be associated with low earnings growth. This notion has been challenged in recent years by empirical research that has found a positive relationship between payout ratio and future earnings growth, both on the aggregated market level and the company level in different countries. This study investigated the aforementioned relationship on the Swedish market by statistically analyzing future earnings growth as a function of payout ratio on a large sample of publicly listed companies over the period 1980 to 2011. The results are in line with those found in previous research and indicate that companies with high dividend payout ratio tend to experience strong future earnings growth. The results are robust to the presence of mean reversion, the use of an alternative accounting measure of earnings, non-symmetrical earnings growth cycles and alternative practices for dealing with outliers..

ABSTRACTA defect implantation process is the major reason for unexplained infertility. Estrogen andprogesterone are steroid hormones preparing the endometrium for implantation. They mediatetheir effect through their receptors: estrogen receptor alpha and beta and progesteronereceptor A and B, respectively. Leukemia inhibitory factor (LIF), which is also important forimplantation, mediates its effect through LIF receptor and the coreceptor, gp130, and is downregulated by suppressors of cytokine signaling 1. The aim of the study was to compare thelevels of the steroid hormone receptors and LIF related factors in the endometrium of twogroups of women with the diagnosis unexplained infertility: one that became pregnant afterassisted reproduction and one that did not become pregnant.

Purpose: The purpose of this thesis is to study the causal relationship between bank sector development and economic growth in four Nordic countries (Sweden, Finland, Denmark and Norway).Method: Our thesis is based on a quantitative method. The study consists of a compilation and analysis of key financial indicators that represent economic growth and bank sector development. A Granger causality test has been conducted on the time series in order to measure the causal link between economic growth and bank sector development.Theoretical framework: The study is based on the theory of endogenous growth and the causal relationship between bank sector development and economic growth also known as the demand following and supply leading hypothesis. Results: The results of the four countries are ambiguous. Except for Denmark, that follows the supply leading hypothesis, the remaining countries do not show a unanimous result..

The purpose of this review was to study the cow eye physiology, focusing on how it registers light, and to see how light affects the cow?s milk yield. It has been showed in studies that more hours of light per day (16 hours of light a day) as opposed to about 9-12 hours of light a day, increases milk yield for dairy cows. This review contains suggestions on how this is connected with the physiology of the eye. Vision is an important sense for many mammals, and is used to check out the animals surroundings. Sensor cells in the eyeball help in turning photons from the light into signals to the brain.

The aim ofthis study was to examine how economic growth affects the level of democracy inauthoritarian states. Some of these states have experienced high economicgrowth. However, one can discuss how it affects the country?s democratization-process.For that reason this study was needed to contribute to a clarification of howeconomic growth can affect authoritarian rule and democratization. This wasdone through an examination of the development in China.

Recent years there has been discussed how the critical situation in the housing market threatens the Stockholm region's growth. The thesis objective is to examine whether there is a scientific link between the lack of housing supply and growth. The thesis also intends to identify solutions for increased housing construction, for instance by examining the conditions for a greater regional perspective and influence on the region's housing supply. The thesis empirical study is based on semi-structured interviews with representatives from the Government, municipalities and the housing industry.In Sweden, research on the relationship between housing shortages and growth has not been conducted to that extent it can be said to exist scientific evidence regarding the growth threat. However, in Britain and the U.S, empirical studies show that a lack of housing supply has hindered growth through negative impact on countries' gross domestic product.

As well as other politic fields, the cultural politics adapt to changes in society. The development in society has brought attention to the interaction between the cultural field and the economic field. One of the main goals within Swedish Cultural Policies today is the development of cultural and creative economics. Politicians and researchers claim that culture can be a significant part in economic growth in cities and making a place attractive to live in.I became interested in the discussion around the cultural experience as a factor of economic growth when I participated in a seminar at Karlstad CCC during Kulturparlamentet 2012. When I then started working at the music festival Putte i Parken during the spring of 2013 I thought about making this study.The main aim is to investigate in which way Putte i Parken can be a factor of growth and a factor of making Karlstad an attractive place to live in by analyzing documents, reports and literature in a qualitative way of working.

The purpose of this study is to make a close and critical scrutiny of the EU Lisbon Strategy and the assumption of `sustainable growth´. A basic question is to clarify what is meant by `sustainability´ in the economic and the environmental dimension respectively, and also, to analyse the meaning of `sustainable growth´. Secondly, I try to investigate the relationship between the economical and environmental dimensions of the strategy. Are the goals of the dimensions compatible and mutually supporting or are they conflicting? By illuminating these issues the study moves towards a final set of questions: What are the arguments that encourage or counteract the Lisbon assumption of `sustainable growth´? Is the European Union approaching `sustainable growth´ looking at different economical and ecological indicators? What are the prospects for the Lisbon Strategy as a way towards global `sustainable development´?.

Development of morphs within European whitefish (Coregonus lavaretus), might be considered as a beginning of a sympatric speciation process. Unpublished data suggests that presence of the keystone piscivore northern pike (Esox lucius) is the main driver of sympatric divergence in European whitefish (Coregonus lavaretus). Using introduced whitefish populations as controlled experiments, it is possible to determine when different characters diverge in the speciation process. In this study, I analysed age and growth within European whitefish populations of different age to assess if these characters change over time in absence of pike. With using otoliths from whitefish populations of different age, I was possible to determine individual age, and by measuring the length of the fish, growth was calculated.

Many sources point to the same conclusion; throughout the history the research sphere, mass media, governmental industry policies and public life in common have not paid the same attention to medium-sized companies as to small, new or large companies in Sweden. Yet, there are some researchers claiming the need for the medium-sized companies to grow, becoming tomorrow?s Swedish new large companies. Hence, the need for understanding the specific growth conditions of the medium-sized companies are definitely clear. This study aims firstly to identify whether there are specific requirements and obstacles for growth in connection to being a medium-sized company.

Immunisering mot gonadotropin-releasing hormone (GnRH) har visat sig vara effektivt mot att hämma galtlukt på griskött och oönskat aggressivt beteende bland hangrisar. I ett samhälle där vi sätter allt högre krav på våra produktionsdjurs välfärd är efterfrågan på metoder som inte innebär smärta eller lidande för djuren stor. Det finns dessutom positiva produktionsrelaterade effekter med immunokastrering gentemot klassisk kirurgisk kastrering, såsom ökad tillväxtpotential. Faktorer som dessa talar för immunokastrering, men samtidigt finns många svårigheter med att vaccinera mot något kroppseget och således bryta kroppens tolernas mot självt. Den här litteraturstudien behandlar svårigheterna med att rikta ett vaccin mot ett endogent hormon, vad som har lett fram till dagens upptäckter och de eventuella problem som kan uppstå i framtiden.
