Ett klimat i förändring är något som påverkar oss alla. För staden och dess invånare innebär det bland annat mer nederbörd och en ökad risk för översvämningar. Det är därför viktigt att arbeta med klimatanpassningsåtgärder.Tanken med den här broschyren är att visa vilka lösningar som naturen kan bidra med. Den fokuserar på ett redan bebyggt område; Sofielund i Malmö. Innehållet bygger på intervjue

The paper analyses dwell time delays for commuter trains in Stockholm and Tokyo. In both cities, small dwell time delays of at most five minutes make up around 90% of the total delays. Therefore, it is valuable to understand and deal with these disturbances. To this end, we use high resolution data on dwell times and passenger counts from both countries over the last several years. We find that thThe paper analyses dwell time delays for commuter trains in Stockholm andTokyo. In both cities, small dwell time delays of at most five minutes makeup around 90% of the total delays.

A 9-year-old boy sustained a Salter-Harris Type IV fracture in the proximal tibia. the injury resulted in a progressive valgus deformity, detected already after 3 months by roentgen stereophotogrammetry. After temporary stapling medially, the growth rate increased laterally and the deformity was corrected. Unilateral stapling is an alternative procedure for correcting angular deformity following a

Growth during adolescence was analyzed in 40 children with slipped capital femoral epiphysis using the Infancy Childhood Puberty growth model. the advantage of this model is that reference values for height can be adjusted for the individual age at pubertal maturation. In both sexes an above average height was found before the onset of the pubertal growth spurt. However, the pubertal gain in heigh

Five hundred thirty-two cases of slipped capital femoral epiphysis (physiolysis colli femoris - PCF) treated at three orthopedic departments in southern Sweden between 1910 and 1982 were used for epidemiologic studies. Three hundred twenty-five cases came from a well-defined area and were used for incidence analyses. During the whole period of investigation, the disease was more common in men than

The present experiment was performed to determine whether different types of grafted central cholinergic neurons are able to form synaptic contacts with host hippocampal neurons. Grafts from the septal-diagonal band area, which contain the neurons that normally innervate the hippocampal formation, were compared to those from the nucleus basalis magnocellularis region (NBM), the striatum, the ponto

En serie av arbeten och installationer som producerades i förhållande till Gemäldegallerie i Berlins konstsamling för den 8 Berlin Biennalen - verken handlade om porträtt som föreställer en okänd person och som är utförda av okända konstnärer

Differential scanning calorimetry was the method to investigate the thermostability of chymotrypsin. The transition temperature decreased by approx. 30°C when the dry enzyme became highly hydrated. High degree of hydration corresponded to extensive conformational changes during protein denaturation, reflected by large enthalpy values. Sorbitol, lyophilized together with the enzyme, caused the dest

In order to evaluate whether there are differences with regard to functionality in starch gel modification between 1‐and 2‐monoglycerides, the gelatinisation of potato starch in the presence of monolaurin, monopalmitin and monoolein has been examined. When the temperature was increased by 1°C/min from 20°C to 80°C there was a significant difference in gel volume between samples containing 1‐monola

The reaction kinetics of αchymotrypsin (EC 3.4.21.1.) catalyzed esterification of N-protected phenylalanine with ethanol were studied. The enzyme was deposited on Chromosorb and reactions were performed mainly in water-saturated mixtures of ethyl acetate and heptane, but also other media were used, such as mixtures of ethyl acetate and acetonitrile. The hydrophobicity of the substrate was varied b

For another year, high-quality research studies from around the world transformed the annual ERS International Congress into a vivid platform to discuss trending research topics, to produce new research questions and to further push the boundaries of respiratory medicine and science. This article reviews only some of the high-quality research studies on asthma, chronic obstructive pulmonary diseas
