Människor har att tacka fotosyntesen för sin existens. Fotosyntesen sker inuti bladen hos högt stående växter, alger, samt hos vissa mikroorganismer (t ex gröna svavelbakterier, cyanobakterier, etc). Fotosyntesens första steg involverar uppfångandet av ljus och överförandet av dess energi till något som kallas reaktionscentrat. Processen involverar en molekyl som kallas (bakterie)klorofyll. Där fiThe purpose of this study is two-fold: first to validate previous findings, that showed that the central atom in (bacterio)chlorophyll changes ligand coordination number upon being cooled at a certain rate (in certain solvents), and to resolve the Qx and Qy bands from the total absorption spectrum. We studied bacteriochlorophyll A (BChl A), bacteriochlorophyll C (BChl C), and chlorophyll A (Chl A)

Demands for socialization understood as the collective, democratically governed ownership of essential goods, are growing louder in Germany’s energy sector. This thesis critically examines how German labor unions and environmental NGOs articulate the concept of socialization within the energy sector, using Antonio Gramsci’s cultural hegemony and Nancy Fraser’s progressive neoliberalism as theoreti

With ongoing strains and disparities in the healthcare system, Generative AI applications are increasingly viewed as promising tools to alleviate pressure in this sector.

Varför kriminaliseras och stigmatiseras vissa droger, när andra förblir både socialt och juridiskt accepterade, trots liknande skadeverkningar? Denna fråga utgör en central utgångspunkt i den svenska drogdebatten, där alkohol är en laglig substans med stark kulturell acceptans, medan narkotika juridiskt definieras som förbjudna ämnen med skadliga eller beroendeframkallande effekter. Syftet med den

Bakgrund: På HVB (Hem för Vård eller Boende) hem bor individer i varierande åldrar med problematik såsom missbruk och psykiatriska diagnoser, där brist på struktur och meningsfull vardag ofta utgör ett hinder för utveckling.
