Photosynthesis in light which is so weak that excitation rates are comparable to the decay rates of S-states is modelled. It is found that oxygen evolution rate varies in a non-linear way with Photosystem II excitation rate in this region, but asymptotically approaches a linear relationship (with a slope of one oxygen molecule per four excitations) as excitation rate increases. The asymptote gives

Dramatic swings in the North Atlantic oscillation (NAO) during the 1990s motivated the authors to build a statistical model of NAO impacts on hydropower production and energy markets in Scandinavia. Variation in the NAO index is shown to explain 55% of the variance of streamflow in Norway and up to 30% of the variance in Norway's hydropower output. It is also possible to identify the influence of

In the study of economic-geographic structures, the shifting focus from the national state to the city and its region has highlighted the lack of reliable interurban data sets. The abundance of usable data sets on international structures and ?ows has no counterpart when studying interurban relations, which makes it hard to draw any extensive conclusions regarding the structure of world city netwo

Advancing on preliminary research, the aim of this work was to further study how partial air dehydration applied to fruit pieces before freezing, alone or in combination with osmo-dehydration, could improve not only quality of strawberry slices used in yogurt preparation but also yogurt characteristics. Raw (NT), air-dehydrated (D), and osmo-air-dehydrated (OD) strawberry slices (cv. Tethis) were

Much attention is now being paid to health and nutrition claims for foods. There are already many food products on the market with claims appealing to consumers about health effects beyond provision of basic nutrients. One important basis for claims is the increasingly documented effect of dietary components on body functions. There are three main reasons for assessing the scientific substantiatio

The results of primary hip replacements are good. However, dealing with a loose prosthesis has been problematic, especially when major bone deficiencies are encountered. These problems appear to have been solved by the introduction of the Slooff-Ling method of using morselized and impacted allograft chips. The clinical results are excellent in the hands of the innovators. However, it remains confu

Objective: To develop evidence-based recommendations for the management of systemic glucocorticoid ( GC) therapy in rheumatic diseases. Methods: The multidisciplinary guideline development group from 11 European countries, Canada and the USA consisted of 15 rheumatologists, 1 internist, 1 rheumatologist-epidemiologist, 1 health professional, 1 patient and 1 research fellow. The Delphi method was u

Popular Abstract in Swedish Den moderna tekniken att operera förslitna höftleder infördes av John Charnley i England på 1960-talet. Lårbenshuvudet ersattes med en metallkula på ett skaft och ledhålan på bäckenbenet med en skålformad plastkomponent. Bägge komponenterna sattes fast med en härdande plast, s.k. bencement. I början uppstod komplikationer med infektioner eller brott i själva protesen. DThis thesis focuses on the healing and remodeling of the morselized and impacted bone allograft, commonly used in revision of loosened hip prostheses with osteolysis. The influence on remodeling by the impaction procedure per se was analyzed, as well as the effects of endogenous bone graft proteins, and an exogenously applied growth factor (OP-1). A bone chamber model in rats was used, with the in

Phenotypic plasticity may enable organisms to optimize their phenotypes in environments that are heterogeneous over time or space. For example, inducible defenses are favored for prey populations faced with variable predation risk. We studied the impact of brook trout (Salvelinus fontinalis) on the development of defensive morphological characters in larvae of the mayfly, Drunella coloradensis, bo

Applying the concept of virtual history, it is possible to reconcile the Soviet history of East Prussia with what came before not only by writing history in a conciliatory and objective manner, but also by presenting the past as one. With this I mean that it is possible to transcend the time dimension and to supersede the notion of history as a chain of events. History need not be written in books

In this thesis, the idea of Knowledge Management (KM) and the planning of the introduction of what is called a “KM approach” in the European Parliament (EP) is studied. The first purpose is to analyze how existing KM thoughts can be supplemented by insights from a subset of democratic theory (e-democracy), by placing focus on the elected representative and his or her information needs. Five “democ

This thesis answers the question whether opt-outs cause Danish political actors to lose Political Capital at the EU-level. In order to do this, Political Capital Theory is developed to fit a European Union context. The theory is then applied to data gathered from Danish political actors and other actors with great experience from the EU. From this, within the premises set by this thesis, it is pos

Mergers and acquisitions on the Swedish market 1997-2009 have created value of approximately 3.5 percent on average measured as abnormal returns. The results are statistically significant. No significance was found for the explanatory regressions and thus we can not find any guidance for managers of when it is preferable to engage in M&A transactions.

International trade has been put forth by the EU as Africa’s most significant opportunity for economic development. Yet, challenges for African exports to the EU persist. This bachelor’s thesis explores the challenges faced by small businesses importing African products in Malmö and Lund, Sweden. It does so through interviews with stakeholders involved in the import process: owners of shops import

This thesis focuses on the issue of abortion rights in the Philippines, a country which maintains one of the strictest abortion laws globally, prohibiting abortion under all circumstances without exceptions. Despite severe penalties, unsafe abortions remain widespread, resulting in approximately 1.1 million induced abortions and around 1,000 maternal deaths annually. The interaction between the Ph

Sexually reproducing species tend to have reproductive barriers between them that prevent hybrid offspring from being formed. Drosophila melanogaster and D. simulans are two closely related species that can form sterile hybrids. In addition to their post-zygotic barriers, which cause the hybrid sterility, some behavioral pre-zygotic barriers also exist. These include different preferences for cour

Syftet med denna studie är att analysera om aktieoptioner till ledningen påverkar deras risktagande, genom att använda aktiekursvolatilitet som ett mått på detta risktagande. Studien syftar till att undersöka detta inom kontexten av europeiska företag. Studien utgår från en deduktiv ansats, där hypoteser formuleras baserat på agentteorin och stewardshipteorin och testas kvantitativt genom regressi
