Multiple Antenna Terminals in Realistic Environments - A Composite Channel Modeling Approach

Popular Abstract in Swedish Mobiltelefonanvändandet förändrades radikalt för några år sedan när de nya grafiska ”touchmobilerna” lanserades och mobilt internet blev inte bara tillgängligt utan också enkelt och använbart för alla. Idag är en ”smart-phone” i det närmaste obligatorisk i handen på såväl vuxna som ungdomar och kraven på datatakt och åtkomst är höga och ökar när allt fler samtidigt anväFor evaluation of specific antenna arrangements in wireless communication systems we need physical channel models that take into account also the directional domain of the propagation channel. In this thesis we investigate, validate and propose a practical approach to wireless channel modeling and, particularly, to mobile communication systems. For this we make the assumption that the channel can

Beyond the Catchwords : Adjustment and Community Response to Participatory Development in Post-Suharto Indonesia

Popular Abstract in Swedish Folkligt deltagande är något av en paroll i dagens utvecklingstänkande. När människor deltar i beslutsfattande och samhällsplanering på lokal nivå blir resultatet bättre och mer anpassat till lokala behov, särskilt i jämförelse med expertorienterade och centraliserade utvecklingsstrategier. Samtidigt kräver detta att folk i allmänhet vill delta och de har ett intresse aThe emphasis on people-centred development is distinctive in today’s development discourse. This is noticeable in catchwords like democratic decentralisation, participation, and empowerment, which are highly esteemed among NGOs, donors, and policymakers in recipient countries. The benefits of participatory approaches are several. When people influence the process of development, policies and pro

Investigation of Type 2 Diabetes Risk Alleles Support CDKN2A/B, CDKAL1, and TCF7L2 As Susceptibility Genes in a Han Chinese Cohort

Background: Recent genome-wide association studies (GWASs) have reported several genetic variants to be reproducibly associated with type 2 diabetes. Additional variants have also been detected from a metaanalysis of three GWASs, performed in populations of European ancestry. In the present study, we evaluated the influence of 17 genetic variants from 15 candidate loci, identified in type 2 diabet

Factors Associated With Maternal-Reported Actions to Prevent Type 1 Diabetes in the First Year of the TEDDY Study

OBJECTIVEMothers of children at risk for type 1 diabetes report engaging in preventive behaviors. The purpose of this study is to further document these actions in an international, longitudinal sample and examine variables that predict whether mothers engage in these behaviors.RESEARCH DESIGN AND METHODSThis study examined an international sample (from Finland, Germany, Sweden, and the U.S.) from

Gastrointestinal motility and the role of gonadotropin-releasing hormone (GnRH)

Popular Abstract in Swedish Könshormon påverkar tarmrörelser Många av kroppens funktioner styrs av hormoner. Att hormoner som vi i första hand förknippar med fortplantning också skulle kunna spela en avgörande roll för tarmfunktion är dock en relativt ny upptäckt. Få saker är så viktigt för en människas välbefinnande som en välfungerande magtarmkanal. De flesta av oss tänker inte på att frukostfrThis thesis explores the relation between gonadotropin-releasing hormone (GnRH) and gastrointestinal symptoms and dysmotility. In primary Sjögren’s syndrome (pSS), a patient group with high levels of GnRH antibodies, associations between objective signs and symptoms of autonomic dysfunction (AD), impaired gastric emptying (IGE), and inflammatory and serological features were studied. Forty-three

Effects of nutrients and fish on periphyton and plant biomass across a European latitudinal gradient

Replicated, factorial mesocosm experiments were conducted across Europe to study the effects of nutrient enrichment and fish density on macrophytes and on periphyton chlorophyll a (chl-a) with regard to latitude. Periphyton chl-a densities and plant decline were significantly related to nutrient loading in all countries. Fish effects were significant in a few sites only, mostly because of their co

Syrgas eller Sobril? Om prioriteringar och val i livets slutskede

Texten fokuserar några valsituationer efter besked om obotlig cancer. Sådant som: Vem ska vi berätta för? Acceptera behandling som kemoterapi eller ej? Ta livet av sig eller ta kampen? Döva sina känslor med medicin eller sträva på med hjälpmedel som syrgas och rullator?

On the coupling of intermolecular polarization and repulsion through pseudo-potentials

To improve the accuracy and transferability of molecular mechanics force fields, one needs a simple physical description of intermolecular polarization based on quantum chemistry. Ideally, in the quantum-chemical description, each molecule is treated separately and the interactions with other molecules are included as a perturbation. We propose a simple formulation of this perturbation, viz. to mo

Risk Conferred by HLA-DR and DQ for Type 1 Diabetes in 0-35-Year Age Group in Sweden

HLA DR4-DQ8 and DR3-DQ2 haplotypes account for 89% of newly diagnosed cases of type 1 diabetes (T1D) in Sweden. The presence of a single copy of DQ6 confers protection. The aim of the present study is to evaluate whether the risk conferred by high risk HLA DR and DQ to T1D is similar in all regions of Sweden and see whether there are any significant regional differences. The subjects comprised 799

För ett bättre Lunds universitet nu

Kollektivt författad skrivelse, "För ett bättre Lunds universitet nu", om villkoren för unga forskare vid LU, publicerad i LUM nr 7/2015, s. 34 under rubriken "Ta vara på unga forskares kapacitet!".

Monitoring Arthritis - Biochemical, Metodological and Clinical Aspects

Arthritides are musculoskeletal diseases, which predominantly affect the joints e.g. osteoarthritis (OA) and rheumatoid arthritis (RA). Modern treatment strategies include early detection and careful monitoring of the disease course. Close monitoring is also the basis for individualized treatment. Monitoring should be done using methods reflecting different aspects of the disease to get a broad pe

The view from below - a management system case study from a meaning-based view of organization

This paper reports on a case study, which investigated energy management and environmental management at a large-scale research facility. The author used the perspective of the managed personnel rather than the management, the entity or the management system. The focus of the research was on interpretation of work, particularly how employees' perceptions of priorities were affected by management i

Expression of Luteinizing Hormone Receptor in the Gastrointestinal Tract in Patients with and without Dysmotility.

Leuprolide is a gonadotropin-releasing hormone (GnRH) analog which has been shown to reduce symptoms in patients with irritable bowel syndrome (IBS) and chronic intestinal pseudo-obstruction (CIPO). The mechanism is not known, but one hypothesis is through down-modulation of luteinizing hormone (LH) secretion, a hormone whith antagonistic effect on gastrointestinal motility. However, presence of L

Differences and similarities in enzymes from the neopullulanase subfamily isolated from thermophilic species

Six glycoside hydrolase (GH) family 13 members, classified under the polyspecific neopullulanase subfamily GH13_20 (also termed cyclomaltodextrinase) were analysed. They originate from thermophilic bacterial strains (Anoxybacillus flavithermus, Laceyella sacchari, and Geobacillus thermoleovorans) or from environmental DNA, collected after in situ enrichments in Icelandic hot springs. The genes wer

Obesity attenuates gender differences in cardiovascular mortality

Background: To estimate cardiovascular disease (CVD) mortality in relation to obesity and gender. Methods: Data from 11 prospective cohorts from four European countries including 23 629 men and 21 965 women, aged 24 to 99 years, with a median follow-up of 7.9 years were analyzed. Hazards ratios (HR) for CVD mortality in relation to baseline body mass index (BMI), waist circumference (WC), waist-to

Serine/arginine-rich protein 30c activates human papillomavirus type 16 L1 mRNA expression via a bimodal mechanism

Two splice sites on the human papillomavirus type 16 (HPV-16) genome are used exclusively by the late capsid protein L1 mRNAs: SD3632 and SA5639. These splice sites are suppressed in mitotic cells. This study showed that serine/arginine-rich protein 30c (SRp30c), also named SFRS9, activated both SD3632 and SA5639 and induced production of L1 mRNA. Activation of HPV-16 L1 mRNA splicing by SRp30c re
