A reaction system consisting of terephthalic acid, NaOH, inorganic Mn(II) or Mn(III) salt, and salicylidene alkylimine resulted in dinuclear manganese complexes (salpn)(2)Mn-2(mu-phth)(CH3OH)(2) (1, salpn = N,N'-1,3-propylene-bis(salicylideneiminato); phth = terephthalate dianion), (salen)(2)Mn-2(mu-phth)(CH3OH)(2) (2, salen = N,N'-ethylene-bis(salicylideneiminato)), (salen)(2)Mn-2(mu-phth)(CH3OH)
In vitro, expanded neurospheres exhibit multipotent properties and can differentiate into neurons, astrocytes and oligodendrocytes. In vivo, cells from neurospheres derived from mouse fetal forebrain have previously been reported to predominantly differentiate into glial cells, and not into neurons. Here we isolated stem/progenitor cells from E13.5 lateral ganglionic eminence (LGE), medial ganglio
Fire functional traits (postfire resprouting and seeding) are considered to be adaptations for persisting in fire-prone environments. Although ecological and evolutionary consequences of sprouting have been extensively discussed, within-species genetic variability and structure are unknown. Here we report levels and distribution patterns of genetic polymorphisms in postfire stands of the predomina
This study focusses on the urban infrastructure for water supply in Roman Pompeii. The water distribution network of lead pipes was constructed inside the city walls, at the time when the city was connected to an aqueduct. Life for the Pompeiians changed considerably when aqueduct water started running continuously in street fountains all around the city. The study is based on previous research an
Keynote paper The point of departure for this lecture lies in the insight that tourism research is uniquely positioned at the juncture of applied and scholarly research. Drawing upon work I have conducted in the realms tourism and leisure study, the lecture strives to problematize the practice of ethnography as a method and raise questions concerning the opportunity research in the fields of tour
Respiration in animals, plants and many bacteria is dependent on heme A, which functions as a prosthetic group in a-type cytochromes (terminal energy-transducing oxidases in the electron transport chain that reduce molecular oxygen to water). Heme A synthase catalyses a chemically very demanding reaction, the conversion of one specific methyl side-group of heme O to a formyl group of heme A. This
Aims/hypothesis: Genome-wide association studies (GWAS) have identified more than 65 genetic loci associated with risk of type 2 diabetes. However, the contribution of distorted parental transmission of alleles to risk of type 2 diabetes has been mostly unexplored. Our goal was therefore to search for parent-of-origin effects (POE) among type 2 diabetes loci in families. Methods: Families from the
The major histocompatibility complex (MHC) is a membrane protein group of central importance in the immune system. It is divided into two main classes, class I and class II. The MHCs are highly polymorphic which is believed to be indication of trans-species polymorphism (TSP). There is TSP when an allele is maintained in two species through a speciation event. The songbirds that I study here belon
This report deals with lime modification of clay till. Lime modification means that the compaction properties of the soil are improved by the addition of lime. The report consists of three main parts: 1) Description of the geotechnical properties of clay till and how lime modification affects the properties; 2) Description of the implementation of lime modification and the tests conducted at a con
Although most microplastics (<5 mm in length or diameter, depending on shape) are not visible they can be found everywhere in the environment. The effects can be devastating and much greater than what has been proven so far, as there is a lack of knowledge about the impact, spread and extent of microplastics. The Swedish EPA published a report in June 2017 which reveals a number of major microplas

Depth data and bathymetry maps are used to analyze their association with tides, winds, currents and wave conditions in the port of Talara, at the coast of northern Peru. The objective is to investigate the processes that influence the sediment transport in the port. The sedimentation affects the saltwater pumps for fire fighting, obstructing them from delivering water since their operational wate
The idea of energy efficient, healthy buildings has existed since 1970s. However, a one-dimensional approach for many housing issues does not assure sustainability. Therefore, near the end of the 20th century, the built environment became a focus of attention within the environmental movement with wider focus on building certification schemes and sustainability issues such as interrelationships be
Personuppgifter och användarinformation har länge använts av företag som en grund för att kunna optimera och utveckla tjänster. I takt med internets explosionsartade framväxt har dock denna användning kommit att få ett större kommersiellt värde än någonsin tidigare. Detta på grund av att teknikens utveckling har medfört att allt större delar av vår vardag sker i anslutning till en internetuppkoppl
Malaria is a global health issue affecting hundreds of millions of people worldwide and accounts for as much as 405 000 deaths annually. Preventative actions are taken but are seemingly not enough to eradicate the spread. Targeting underlying molecular mechanisms behind the host-seeking behavior of the principal malaria vector Anopheles gambiae, would offer a new approach in the development of an
Att jag intresserar mig för stranden som plats för mitt examensarbete är kanske inte så konstigt. Som vågsurfare har jag tillbringat mycket tid på stranden och ute bland vågorna. Genom surfingen har jag upplevt många olika kuststräckor och vågor på jorden, men just stranden och surfingen i Sverige har fångat mitt intresse. Här är årstidernas förändringar och havets stormar de största utmaningarna,It is not that surprising that I chose the beach as the subject of my thesis. As a surfer, I have spent a lot of time on the beach and among the waves. Through surfing I have experienced a wide variety of coastlines around the world, but the beaches of Sweden have peaked my interest. The changing of the seasons and the ocean´s storms are the biggest challenges here for a surfer, not the size of th
It’s been 34 years ago now since the iron curtain has parted the European continent and its inhabitants in an East and a West. The analysed area for the following thesis on the border between northern Austria and southern Czechia gives a case example of a region, that is still suffering from an era, where one sky-direction has been erased from people’s everyday living and thinking – leaving the bo
