The S1 split signal of photosystem II; a tyrosine-manganese coupled interaction

Detailed optical and EPR analyses of states induced in dark-adapted PS II membranes by cryogenic illumination permit characterization and quantification of all pigment derived donors and acceptors, as well as optically silent (in the visible, near infrared) species which are EPR active. Near complete turnover formation of QA- is seen in all centers, but with variable efficiency, depending on the d

The S0 state of the water oxidizing complex in photosystem II : pH dependence of the EPR split signal induction and mechanistic implications

Water oxidation in photosystem II is catalyzed by the CaMn4 cluster. The electrons extracted from the CaMn4 cluster are transferred to P680+ via the redox-active tyrosine residue D1-Tyr161 (YZ). The oxidation of YZ is coupled to a deprotonation creating the neutral radical YZ•. Light-induced oxidation of YZ is possible down to extreme temperatures. This can be observed as a split EPR signal from Y

The Streets are Talking to Me : Affective Fragments in Sisi’s Egypt

This sophisticated book presents new theoretical and analytical insights into the momentous events in the Arab world that began in 2011 and, more importantly, into life and politics in the aftermath of these events. Focusing on the qualities of the sensory world, Maria Frederika Malmström explores the dramatic differences after the Egyptian revolution and their implications for society—the lack of

Concentration of citrus fruit juices in membrane pouches with solar energy Part 1 : How solar drying setup and juice pretreatment determine the drying flux

The aim of this study was to investigate how solar drying setup and choice of juice pretreatment determine the drying flux in a fruit juice concentration process called solar assisted pervaporation. With this process, hygienic membrane pouches and solar energy are used to concentrate and preserve fruit juices. In this study, the feasibility of concentrating citrus (tangerine) juice into marmalade

Pragmatism i dansk sakrätt – särskilt om panträttsliga aspekter

Trots att nordisk rätt i stor utsträckning präglas av en funktionalistiskt inställning så skiljer sig uppfattningen om hur frågeställningar inom den dynamiska sakrätten ska lösas länderna emellan. I artikeln åskådliggörs hur det svenska förhållningssättet präglas av lagstadgade regler, medan det i Danmark finns en mjukare och tämligen pragmatiskt attityd med utrymme för mer nyanserade lösningar. F

Säkerhetsutbildningar och säkerhetskulturarbete vid forskningsanläggningar med strålningsrisker och många tillfälliga internationella användare – ett fortsättningsprojekt

Det övergripande syftet med detta projekt har varit att ge ett konkret underlag somkan användas som stöd för att utveckla välfungerande kortare säkerhetsutbildningar i säkerhetskritiska verksamheter.Utgångspunkten har varit forskningsanläggningarna MAX IV och EuropeanSpallation Source (ESS) där forskare, dvs användare, från hela världen vistas tillfälligt för att genomföra experiment. Användarna k

Nomenclature and semantic descriptions of ulcerative and inflammatory lesions seen in Crohn’s disease in small bowel capsule endoscopy : An international Delphi consensus statement

Background: In the medical literature, the nomenclature and descriptions (ND) of small bowel (SB) ulcerative and inflammatory (U-I) lesions in capsule endoscopy (CE) are scarce and inconsistent. Inter-observer variability in interpreting these findings remains a major limitation in the assessment of the severity of mucosal lesions, which can impact negatively on clinical care, training and researc

Protecting OpenFlow using Intel SGX

OpenFlow flow tables in Open vSwitch contain valuable information about installed flows, priorities, packet actions and routing policies. Their importance is emphasised when collocated tenants compete for the limited entries available to install flow rules. OpenFlow flow tables are a security asset that requires confidentiality and integrity guarantees. However, commodity software switch implement

International classification of abdominal wall planes (ICAP) to describe mesh insertion for ventral hernia repair

Background: Nomenclature for mesh insertion during ventral hernia repair is inconsistent and confusing. Several terms, including ‘inlay’, ‘sublay’ and ‘underlay’, can refer to the same anatomical planes in the indexed literature. This frustrates comparisons of surgical practice and may invalidate meta-analyses comparing surgical outcomes. The aim of this study was to establish an international cla

Ocean acidification increases iodine accumulation in kelp-based coastal food webs

Kelp are main iodine accumulators in the ocean, and their growth and photosynthesis are likely to benefit from elevated seawater CO2 levels due to ocean acidification. However, there are currently no data on the effects of ocean acidification on iodine metabolism in kelp. As key primary producers in coastal ecosystems worldwide, any change in their iodine metabolism caused by climate change will p

Self-Service Business Analytics and the Path to Insights : Integrating Resources for Generating Insights

The nature of today’s business demands that Business Analytics (BA) extends to an operational level to better support employees in their decision-making. This is noticeable from the constant requests for new reports and changes in old ones at different employee levels. As a result, BA specialists or other power-users in functional departments are “bombarded” by these requests, and it becomes more

Empowered or Protected? : The ‘problem’ of complainants’ rights in Danish and Norwegian preparatory works on criminal procedure

In the mid-2000s, Danish and Norwegian criminal procedural law underwent legislative amendments to strengthen the rights of complainants in cases of sexual violence and other cases of serious violations. While in Norway complainants were afforded participatory rights and stronger legal representation in court, this was largely not the case in Denmark. The aim of this chapter is to identify how the

Studying the “Pelagius and Johannes” collection of Sayings of the Desert Fathers : Steps towards a new edition of the Latin reception

The sayings of the Desert Fathers had an important role in the monastic education and were very widespread. Originally written down in Greek, they were soon translated into all the main languages in the medieval Europe, and underwent transformations as they were copied. The sayings were organized in different ways, mainly alphabetically or according to themes, and as they were copied the repertoir
