We investigate whether it is possible that viable microbes could have been transported to the Earth from planets in extra-solar systems by means of natural vehicles such as ejecta expelled by comets or asteroid impacts on such planets. The probabilities of close encounters with other solar systems are taken into account as well as the limitations of bacterial survival times inside ejecta in space,
The concept of disaster risk reduction has gained more and more attention since the end of the 20th century due to the exponential increased loss of human lives and material losses, without any evidence of increased number of hazardous events. Instead of just managing disastrous events, a greater emphasis has been put on prevention efforts; an understanding of underlying drivers and vulnerabilitie

One of the defining features of the post-Cold War era is the growth of international migration in all areas of the world, especially in Europe, where the lift of the Iron Curtain created needs and opportunities as far as immigrants are concerned. Although a beneficial process in itself, the growth of migration to Europe was frequently a cause of various forms of conflict, which in the social scien
Vätgas är en energikälla som har en energidensitet (per massa) tre gånger så stor som naturgas. Detta gör så att vätgas är en huvudkandidat för morgondagens bränsle. Ett av de viktigaste forskningsområderna för vätgas innefattar produktion av vätgas eftersom det finns en stor mängd metoder för vätgasproduktion. Återvinnbar vätgas kan potentiellt produceras med vattenelektrolys, som undersöks i detHydrogen gas is an energy source that has an energy density (per mass) that is three times as large than the energy density of natural gas. This qualifies hydrogen gas as a prime candidate for the fuel of tomorrow. One of the main research areas for hydrogen include the production of it as there are a vast amount of methods of hydrogen production. Renewable hydrogen can potentially be produced thr
Det utbredda tiggeriet i Europa öppnar upp för många frågor. I Sverige är regleringarna kring tiggeri relativt oklara. Efter min tolkning av gällande rätt visas att tiggeriet inte är förbjudet och inte heller tillståndspliktigt enligt ordningslagen. Dock finns det vissa möjligheter att genom lokala ordningsföreskrifter belägga det aktiva tiggeriet med tillståndsplikt med hänsyn till att det stör dThe widespread panhandling taking place in Europe opens for many questions. In Sweden, the regulations regarding panhandling is diffuse. According to my interpretation panhandling is not forbidden nor a subject to permission under ordningslagen. However, there are some possibilities to prohibit the active panhandling through local regulations with the means that it disturbs the public order. Prohi
In recent years, several men in Sweden have been acquitted of different sexual offences because the courts deemed that it could have occurred in their sleep. According to a leading expert, several of the Swedish acquitting cases are based on incorrect or irrelevant arguments and reasoning regarding sexsomnia. Therefore, it is important to gain a deeper understanding of how sexsomnia manifests with
Denna framställning behandlar ämnet surrogatmoderskap. Surrogatmoderskap innebär att en kvinna genomgår en graviditet för ett barnlöst pars räkning, vilka benämns ”det beställande paret”. När barnet föds överlämnas det till det beställande paret som således blir barnets sociala föräldrar. Genetisk sett kan barnet vara helt och hållet det beställande parets eget eller kan surrogatmodern även ha bidThe theme of this essay is surrogate motherhood. This is the practice whereby one woman carries a child for another woman. The other woman and her partner are called the commissioning couple. When the surrogate mother has given birth, the child is handed over to the commissioning couple. The commissioning couple may be the genetic parents of the child, or the surrogate mother may have contributed
Second homes, or summer cottages, are widely spread all over Finland. It is estimated that half of the country´s population have an access to one or several second homes. The phenomenon constitutes a remarkable part of how Finns spend their leisure time. Whereas traditional way of life attracts middle aged and retired urban dwellers to return to their roots, increasing number of second home users
Olovligt tillgängliggörande av upphovsrättsligt skyddat material genom fildelning är ett av vår tids mest debatterade ämnen. Teknikens utveckling har gjort det möjligt för enskilda personer att snabbt och kostnadsfritt tillgodogöra sig perfekta kopior av musik och film. Detta resulterar i att kompensation uteblir för upphovsmän och deras rättighetshavare.
