A simple and compact slot antenna with a very wide tuning range is proposed. A 25 mm (roughly equal to λH/8, where λH corresponds to the highest frequency of the tuning range) open slot is etched at the edge of the ground. To achieve the tunability, only two lumped elements, namely, a PIN diode and a varactor diode are used in the structure. By switching the PIN diode placed at the open end of the

Aim: To study self-esteem in clinical sample of obese children and adolescents. Methods: Obese children and adolescents aged 8-19 years (n = 107, mean age 13.2 years, mean BMI 32.5 [range 22.3-50.6], mean BMI z-score 3.22 [range 2.19-4.79]; 50 boys and 57 girls) were referred for treatment of primary obesity. Self-esteem was measured with a validated psychological test with five subscales: physica

The objective was to investigate prevalence, estimate risk factors, and antenatal suspicion of abnormally invasive placenta (AIP) associated with laparotomy in women in the Nordic countries.

A DCIP survey with different timing settings, electrode arrays, cable spreads and waveforms (50\% and 100\% duty cycle waveform) were carried out over the Liikavaara deposit in northern Sweden. All the measured data were inverted using AarhusInv. Measured data with 100\% duty cycle waveform, which is much faster than the conventional 50\% duty cycle waveform, present significant improvements in th

Observations and modeling studies indicate that enhanced vegetation activities over highlatitudes under an elevated CO2 concentration accelerate surface warming by reducing thesurface albedo. In this study, we suggest that vegetation-atmosphere-sea ice interactions overhigh latitudes can induce an additional amplification of Arctic warming. Our hypothesis is testedby a series of coupled vegetation

Popular Abstract in Swedish Luftburna partiklar från transportsektorn och energiproduktion kan ge upphov till negativa hälsoeffekter hos människor och påverka det globala klimatet. Partiklarnas kemiska och fysikaliska egenskaper förändras när de åldras i atmosfären och ny partikelmassa kan bildas från ämnen som tidigare var i gasfas. Det övergripande syftet med den här avhandlingen är att öka kunsEmissions from anthropogenic combustion sources, such as light duty vehicles and small scale biomass combustion, contribute significantly to ambient aerosol particle concentrations both on local and global scales. These emissions have controlling impacts on public health and global climate. The overall aim of this thesis was to investigate how atmospheric transformation and combustion conditions a

Vardagligt tal är i all sin enkelhet en mycket komplicerad process. Lyssnandet likaså. Att över huvudtaget hinna höra och förstå ord som forsar ur någons mun, är ett mindre under. Till synes enkla självklarheter i språket är resultatet av avancerade tolkningar, bedömningar och beslut. Här har mätningar av hjärnaktiviteten under lyssnandet visat sig rymma flera förklaringar till hur pratet når fram
