Solceller – en miljövänlig energikälla? Miljöförstöring i form av växthusgasutsläpp är en gigantisk utmaning som mänskligheten står inför och vi måste agera NU! Solceller innebär en fantastisk möjlighet att utvinna stora mängder “ren” energi från solen. Men hur miljövänliga är egentligen solceller och är det ett effektivt alternativ i Sverige? Varje timme träffas Jorden av tillräckligt mycket eClimate change is one of the greatest environmental challenges at the present time and is currently an issue affecting the entire global population. Alternative renewable energy sources are vital to be able to deal with this challenge. Solar energy is one of the most promising renewable energy sources and is therefore also one of the fastest growing industries in this field. However, solar energy

Jus cogens norms and obligations erga omnes are concepts within international law that are often used to reinforce legal claims. This thesis aims to assess to what extent invoking these concepts, along with their reinforcing capabilities, is justified in specific cases. In order to achieve this, the thesis first gives an overview of the theoretical debate surrounding the concepts of jus cogens no

Shared micro-mobility services are increasingly embraced by cities around the world in recent years. Their benefits over other transportation modes in certain frames encourage traffic/urban planners, public authorities to establish such systems in urban areas. However, planning the placement, size and operation of such beneficial micro-mobility mode is a vital issue that concerns designers. Severa

The growing interdependence and interconnectedness of the global community set the pace and frame for the evolution of foreign policy. Diplomacy formerly being the reserve of international communication has consequently been forced to change and branch out. This essay attempts to view these changes and their context at the example of US foreign policy in Pacific Asia. Both hard power translating i

The accumulation of empirical evidence that outward-oriented developing countries have generally performed better than inward-oriented ones in terms of growth, industrialisation, job creation and other macroeconomic indicators provides an essential lesson for both policy-makers and development economists worldwide. The acknowledged importance of trade and non-traditional exports for development an

Background and Purpose-The proportion of immigrants has increased in Sweden markedly during the last decades, as in many other Western countries. Incidence of stroke has increased during this period. However, it is primarily unknown whether incidence of stroke and stroke subtypes in Sweden is related to country of birth. Methods-Incidence of first-ever stroke was followed during 10 years in a coho

Palaeomagnetic data are used to study the configurations of continents during the Proterozoic. Applying stringent reliability criteria, the positions of the continents at 12 times in the 2.45- to 1.00-Ga period have been constructed. The continents lie predominantly in low to intermediate latitudes. The sedimentological indicators of palaeoclimate are generally consistent with the palaeomagnetic l

Since its composition two centuries ago in 1824, Beethoven’s Ninth Symphony (Ode to Joy) has been heralded the world over not only as a great work of art, but also as a symbol of political importance. In Germany, it was lionised as the embodiment of a national spirit, first during the Franco-Prussian war, then as a prize of the Nazi repertoire; in Rhodesia, it became the national anthem of a far-r

The widely accepted “Milankovitch theory” explains insolation-induced waxing and waning of the ice sheets and their effect on the global climate on orbital timescales. In the past half century, however, the theory has often come under scrutiny, especially regarding its “100-ka problem.” Another drawback, but the one that has received less attention, is the “monsoon problem,” which pertains to the

Shelterbelts (or windbreaks) can effectively improve the microclimate and soil conditions of adjacent farmland and thus increase crop yield. However, the individual contribution of these two factors to yield changes is still unclear since the short-term effect from the microclimate and the accumulated effect from the soil jointly affect crop yield. The latter (soil effect) is supposed to remain af

Ending the use of unabated coal power is a key climate change mitigation measure. However, we do not know how fast it is feasible to phase-out coal on the global scale. Historical experience of individual countries indicates feasible coal phase-out rates, but can these be upscaled to the global level and accelerated by deliberate action? To answer this question, we analyse 72 national coal power p

BACKGROUND: Post-traumatic syringomyelia (PTS) affects patients with chronic spinal cord injury (SCI) and is characterized by progressive deterioration of neurological symptoms. To improve surgical treatment, we studied the therapeutic effects of neuroepithelial-like stem cells (NESCs) derived from induced pluripotent stem cells (iPSCs) in a rat model of PTS. To facilitate clinical translation, we

The regional loess stratigraphy in the Vojvodina region, in the southeastern Carpathian Basin, has often been successfully correlated to the global palaeoclimate. This is a quasi-continuous sedimentary record that provides detailed environmental reconstruction during the last four glacial/interglacial cycles. In this study, we present a standardized loess stratigraphy and illustrate how it correla

INTRODUCTION: Reporting of sex and gender analysis in medical research has been shown to improve quality of the science and ensures findings are applicable to women and men. There is conflicting evidence on whether efforts by funding agencies and medical journals to encourage reporting of sex and gender analysis has resulted in tangible improvements. This study mapped the inclusion of sex and gend
