Dwell Time Delays for Commuter Trains in Stockholm and Tokyo
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.

Stapling for tibial-growth deformity : A case report on roentgen stereophotogrammetric analysis
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 of children with physiolysis of the hip
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
Epidemiology of slipped capital femoral epiphysis in southern Sweden
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
Synaptic connections formed by grafts of different types of cholinergic neurons in the host hippocampus
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

Calorimetric studies on solid α-chymotrypsin preparations in air and in organic solvents
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
Starch Complexing by Enzymatically Prepared 2‐Monoglycerides Compared to Effects by 1‐lsomers
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
Reaction kinetics of immobilized α chymotrypsin in organic media 2. Effects of substrate partition
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
Research highlights from the 2017 ERS International Congress : airway diseases in focus
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
Amelioration of spatial memory impairment by intrahippocampal grafts of mixed septal and raphe tissue in rats with combined cholinergic and serotonergic denervation of the forebrain
Previous studies in the rat have shown that a serotonergic depletion greatly potentiates the learning and memory impairments produced by pharmacological or lesion-induced cholinergic blockade in the forebrain. The impairment produced by combined serotonergic-cholinergic lesions is reminiscent of that seen in memory-impaired aged rats. In the present experiment, we investigated whether grafts of ch

Klimatförändringen, ekosystem och arter
Den pågående klimatförändringen påverkar redan jordens arter och ekosystem på land, i sjöar, vid kusterna och i haven. Den påverkar enskilda arters utbredning och beteende, vilket i sin tur leder till förändringar i den biologiska mångfalden. Även om andra hot mot den biologiska mångfalden hittills dominerat, kommer effekterna på arter och ekosystem att öka med tilltagande klimatförändring med svå
Impact of Excess Lead Iodide on the Recombination Kinetics in Metal Halide Perovskites
Fundmental comprehension of light-induced processes in perovskites are still scarce. One active debate surrounds the influence of excess lead iodide (PbI2) on device performance, as well as optoelectronic properties, where both beneficial and detrimental traits have been reported. Here, we study its impact on charge carrier recombination kinetics by simultaneously acquiring the photoluminescence q
Modulation of the measuring range of a radioimmunoassay using an organic water two phase system
A commercially available radioimmunoassay (RIA) kit was used to study the effects of organic solvents on antigen-antibody interactions. The RIA analysis was carried out in aqueous-organic two phase systems. After exposure to hydrophobic organic solvents the antibodies retained full binding capacity, while less hydrophobic solvents caused partial inactivation of the antibodies. A practical analysis
Effects of subzero temperatures on the kinetics of protease catalyzed dipeptide synthesis in organic media
A depeptide synthesis was drastically influenced by the reaction temperature, in the range from −30° to 25°C. This article shows the kinetic reasons of this effect. α‐Chymotrypsin was immobilized on celite and used in four different water‐miscible solvents containing small amounts of water‐miscible solvents containing small amounts of water. The reaction studied was the aminolysis of N‐acetyl‐L‐ph
