Generalized frequency division multiplexing (GFDM) is a new digital multicarrier concept. The GFDM modulation technique is extremely attractive for applications in a fragmented spectrum, as it provides the flexibility to choose a pulse shape and thus allows reduction of the out-of-band leakage of opportunistic cognitive radio signals into incumbent frequency space. However, this degree of freedom

Laminar burning velocities of syngas/air premixed flames, varying with H-2/CO ratio (from 5/95 to 75/25) and N-2 or CO2 dilution rate (from 0% to 60%), were accurately measured using a Teflon coated Heat Flux burner and OH-PLIF based Bunsen flame method. Experiments were carried out at atmospheric pressure and room temperature, with fuel/air equivalence ratios ranging from fuel-lean to fuel-rich.

Popular Abstract in Swedish Diabetes är en av de vanligaste folksjukdomarna och tusentals diagnostiseras med sjukdomen varje år. Det finns två typer av diabetes, typ 1 och typ 2. I typ 1 förstörs de insulin producerande β-cellerna som finns i de Langerhanska öarna av kroppens immunförsvar. β-cellerna har till uppgift att reglera blodsockernivåerna. Avsaknaden av egen insulinproduktion leder till dDiabetes affects enormous amounts of patients. In type 1 diabetes the insulin producing β cells in the islet of Langerhans are destroyed by the immune system. The β cells, which are located in the pancreas, regulate blood glucose levels. The lack of insulin production requires administration of insulin. This is accomplished by insulin injections. Even though the treatment methods have been improve

Terahertz spectroscopy is employed for the noncontact measurement of transversal mobility in InP nanowires, wherein photonic effects (waveguiding of excitation beam and propagation of terahertz beam in a complex gradient environment) were successfully deconvoluted. Monte Carlo calculations accounting for electron localization and heavy doping were used to determine electron momentum relaxation tim

The intense competition between places means that new and more differentiated marketing strategies are becoming increasingly important in order to attract visitors and other target groups. In order to be seen, gain positive media attention and put the place on the map many cities try to develop marketing concepts based on experiences, among other things. One such strategy used by many places is to

Background: The aim was to describe the feeding-and stooling patterns of infants with colic and evaluate the influence of minimal acupuncture. Methods: A prospective, randomized, controlled, blind clinical study was conducted at a private acupuncture clinic in Sweden. 90 otherwise healthy 2-8 weeks old infants, born after gestational week 36, fulfilling the criteria for infantile colic and not med

In this study we explored how men diagnosed with prostate cancer experienced their sexuality from a lifeworld perspective. One essential meaning was identified: "having the elixir of life stolen." This essential meaning had four constituents: "something that no longer exists," "the threat to manhood," "intimacy," and "staged manhood." The lifeworld for these men comprised the dynamic interaction b

We report the development of a high-level bacterial expression system for the Alzheimer's disease-associated amyloid beta-peptide (A beta), together with a scaleable and inexpensive purification procedure. A beta(1-40) and A beta(1-42) coding sequences together with added ATG codons were cloned directly into a Pet vector to facilitate production of Met-A beta(1-40) and Met-A beta(1-42), referred t

This paper describes how focus group interviews were used in a project on developing research support services. The object of the interviews was to understand the everyday lives of researchers and the obstacles they experience in their research process. Advantages and challenges of the method are discussed, e.g. the benefits of the interaction and the free form that the method allows for and the c

The aim of this pilot study was to assess the association between perceived environmental barriers and perceived participation in everyday life situations encountered by people with late effects of polio. A sample of 45 persons with clinically verified late effects of polio answered the Swedish versions of the Impact on Participation and Autonomy Questionnaire (IPA-S) and the Craig Hospital Invent

Carex digitata and Melica nutans are forest understorey herbs with wide European distributions and their northern range margins in Fennoscandia. The species have closely similar habitat requirements, occur in small populations in old forest stands on base-rich to neutral soils and have restricted dispersal abilities at the present day. This study investigates the structure of allozyme variation (1

The measurement of glycated hemoglobin is central in the monitoring of glycemic control in patients with diabetes. There are at least 30 different laboratory assays commercially available to measure the proportion of HbA1c in blood. In 1995 the IFCC established a Working Group (IFCC WG-HbA1c) to achieve international standardization of HbA1c measurement. The main achievements can be summarized as

Early erythroblasts from patients with refractory anemia (RA) and RA with ringed sideroblasts (RARS) show constitutive mitochondrial release of cytochrome c. Moreover, mature erythroblasts in RARS, but not in RA, display aberrant accumulation of mitochondrial ferritin (MtF). We analyzed cytochrome c release, MtF expression, and gene expression during erythrold differentiation in bone marrow cells

The ribosomal protein S19 (RPS19) is located in the small (40S) subunit and is one of 79 ribosomal proteins. The gene encoding RPS19 is mutated in approximately 25% of patients with Diamond-Blackfan anemia, which is a rare congenital erythroblastopenia. Affected individuals present with decreased numbers or the absence of erythroid precursors in the bone marrow, and associated malformations of var

During the past 20 yr, aquatic microbiologists have reported 2 strong patterns which initially appear contradictory. In pelagic systems, bacterial growth and biomass is well correlated with the growth and biomass of primary producers. However, bacterial respiration often exceeds net primary production, which suggests that bacteria are subsidized by external inputs of organic matter. We hypothesize

Background. Respiratory tract infections (RTI) in children is the most common cause of prescription of antibiotics. It is important to describe and analyse non-medical factors in order to develop more rational use of antibiotics. Objectives. To compare families with high and low concern about infectious illness with regard to social variables, perception of infection proneness and beliefs in antib

A detailed experimental investigation has been made of the pyrolysis-the first step in biomass combustion-of single birchwood particles. In addition to mass spectrometric and gravimetric analysis, the pyrolysis volatiles were characterized by different optical techniques. Absorption measurements showed a nearly featureless absorption in the ultraviolet spectral region with a continuously stronger
