In the study of economic-geographic structures, the shifting focus from the national state to the city and its region has highlighted the lack of reliable interurban data sets. The abundance of usable data sets on international structures and ?ows has no counterpart when studying interurban relations, which makes it hard to draw any extensive conclusions regarding the structure of world city netwo

OBJECTIVE: Despite a change of fetal physiologic and biochemical functions with gestational age, stationary umbilical cord acid-base reference values are used as measures of obstetric care quality. The aim of this study was to assess the risk of low Apgar score relative to low pH when using stationary versus gestational age-adjusted reference values. METHODS: Umbilical artery pH was determined in

Popular Abstract in Swedish De flesta primärar hjärntumörer utgår ifrån astrocyter, oligodendrocyter och ependymala celler, som är hjärnvävnadens egna celler. Cirka hälften av dessa tumörer ingår i en grupp där tumörtypen heter gliom. Glioblastoma multiforme (GBM) är den mest elakartade tumören inom denna grupp och också den vanligast förekommande.Trots stora forskningssatsningar är behandlingsstrGlioblastoma multiforme (GBM) is the most malignant and also the most common form of brain tumour in humans. The overall aim of this thesis was to investigate morphological and diagnostics features in human GBM that may be of importance for prognosis and treatment. Immunohistochemically stained tissue sections have been microscopically analysed regarding immuno-reactive cells, cell proliferation,

This review summarizes and discusses the use of central health registers in studies of causes of congenital malformations. The review is illustrated using data from the Swedish Medical Birth Register with adjacent registers and gives examples of different methods to identify environmental exposures. The review stresses the usefulness of this approach but also the inherent problems of which the res

Reduction of the model platinum(IV) complexes cis-[PtCl4(NH3)(2)] (1), trans-[PtCl4(NH3)(2)] (2). trans-[PtCl2(en)(2)](2+) (3), trans-[PtBr2(NH3)(4)](2+) (4), [PtCl6](2-) (5), and [PtBr6](2-) (6) with L-ascorbic acid (H(2)Asc) in 1.0 M aqueous medium at 25 degreesC in the region 1.75 less than or equal to pH less than or equal to 7.20 has been investigated using stopped-flow spectrophotometry. The

The metallation of tetrapyrroles is believed to proceed via a sitting-atop (SAT) complex, in which some of the pyrrole nitrogen atoms are protonated and the metal ion resides above the ring plane. No crystal structure of such a complex has been presented, but NMR and EXAFS (extended X-ray absorption fine structure) data has been reported for Cu2+ in acetonitrile, which have been interpreted as the

Four wastewater samples of different treatment qualities; untreated, alarm, alert and normal, from a Swedish chen-ti-thermo-mechanical pulp mill and pure water were investigated using an amperometric bioelectronic tongue in a batch cell. The aim was to explore enzymatically modified screen-printed amperometric sensors for the discrimination of wastewater quality and to counteract the inherent drif

In this paper, we consider fundamental limitations for DOA estimation with arbitrary lossless antennas or antenna arrays inserted inside a sphere. Spherical vector modes and their associated equivalent circuits and Q factor approximations are employed as a general framework for the analysis. The classical broadband matching theory by Fano is extended to a general multiport S-parameter model of the

We show the implications of the commonly observed age-related decline in aboveground productivity of forests, and hence forest age structure, on the carbon dynamics of European forests in response to historical changes in environmental conditions. Size-dependent carbon allocation in trees to counteract increasing hydraulic resistance with, tree height has been hypothesized to be responsible for th

Chemiluminescent emission from OH*, CH* and C2* radicals and its dependence on the equivalence ratio is being investigated in the current study. The aim of this project is to use the results for combustion control on marine vessels and safety checks. The study was conducted in collaboration with Kockumation, a leading company in developing control systems for running boilers and steam turbines on

Implementing anammox based processes in the mainstream at municipal wastewater treatment plants is challenging and requires carefully constructed control strategies in order to be successful. A method to measure the specific anammox activity (SAA) was further developed and implemented in the mainstream anammox pilot plant at Sjölunda Wastewater Treatment Plant. The developed method was found to be

This paper examines the relationship between Big Data and two financial assets. This is achieved through replication of the portfolio method proposed by Preis, Moat and Stanley (2013) which examines and tests the relationship between search engine query volumes and financial markets. Collecting data from 98 different search terms, this paper extends the study by applying the strategy to two new fi

The aim of this master thesis has been to develop a Blocking device that makes sure that a Spring parking brake is not unintentionally activated after a manual release. There is also a need for developing a new Piston indicator that should give two signals depending on if the Spring parking brake is active or inactive. Both are supposed to fit with a completely new generation of Spring parking bra

Populärvetenskaplig sammanfattning: Kartläggning av långbensgroda på Öland Amfibier världen över har minskat kraftigt sedan1970-talet. Orsakerna är många men flera är okända. Fem av tretton amfibier i Sverige är hotade och åtgärder genomförs för att öka arters populationer. Biogeografisk uppföljning är ett nationellt program för uppföljning av amfibier som kan upptäcka förändringar i en arts popAs a result of e.g. habitat loss and diseases, a global decline of amphibians is a fact. In order to prevent further declines and to improve the conservation status for amphibians in Europe, the member states have to report the status for amphibians every sixth year to EU. In Sweden, the County Administrative Board in Scania is responsible for coordinating the biogeographic monitoring of amphibian

Many Latin American economies benefited greatly from increasing international trade and an unprecedented commodity boom in the dawn of the 21st century. At the same time the region successfully reduced the prevailing income inequality, apparently without compromising economic growth. These events seem to challenge the common belief of economists, who proclaim the mutual exclusiveness of growth pro
